In some embodiments, in order to perform pre-washing of the clothes, the clothes pre-washing device 100 may include a controller (not shown) (for example, a server, a processor, a microcontroller, a Computer Processing Unit (CPU), or any other computing device). The controller may be configured to operate the clothes pre-washing device 100 based on one or more actions performed by the user to pre-wash the clothes. Examples of a type of clothes that can be prewashed using the clothes pre-washing device 100 may be, but are not limited to baby clothes, kitchen cleaning clothes, handkerchief, socks, tie's, undergarments, or any other similar other small clothing item.

[0020] As depicted via the present FIG. 1, the clothes pre-washing device 100 may be a compact size and space saving device. In other words, the clothes pre-washing device 100 may be designed to be easily positioned on a top of a common front load washing machine or seamlessly fit into a washroom or any other place within a home environment taking up a minimal space. Further, as depicted via FIG. 1, the clothes pre-washing device 100 may include a top lid 102, a washing tank (not shown), an outer casing 104 configured to cover the washing tank, an interactive interface 106, and a feeding tray 108. The top lid 102 may be coupled to the washing tank. In particular, the top lid 102 may be configured to cover or uncover the washing tank. In other words, the top lid 102 may be opened and closed by the user to uncover or cover the washing tank, respectively, as and when required by the user. The user may open the top lid 102 to access the washing tank. For example, the user may open the top lid 102 for adding the clothes to the washing tank.

[0021] Further, the top lid 102 may include at least one ultraviolet-C light, such that the ultraviolet-C light may be directed towards the washing tank. In an embodiment, the at least one ultraviolet-C light may be configured to prevent accumulation of the micro-organisms on the clothes within the washing tank. In other words, the at least one ultraviolet-C light may prevent accumulation of the micro-organisms during pre-washing and storing the clothes in the washing tank of the clothes pre-washing device 100. In particular, the clothes when exposed to the at least one ultraviolet-C light may get sterilized by killing the micro-organisms, such as harmful molds, bacteria, virus, and any other similar micro-organism, from the clothes during the pre-washing and the storing, due to germicidal properties of the at least one ultraviolet-C light.

[0035] Referring now to FIG. 5 an exploded view 500 of the clothes pre-washing device 100 is illustrated, in accordance with some embodiments of the present disclosure. FIG. 5 is explained in conjunction with FIGS. 1, 2, 3, and 4. The clothes pre-washing device 100 may include the washing tank 202. It should be noted that the washing tank 202 may be of a pre-defined capacity (e.g., 20 milliliters). As already explained in FIG. 3, the plurality of equally spaced protrusions (e.g., the protrusion 208) may be made at the pre-defined distance (e.g., 2 centimeters). In an embodiment, each of the plurality of equally spaced protrusions may be present at each inner side wall of the washing tank 202. In an embodiment, each of the plurality of equally spaced protrusions may be configured to effectively distribute the ultrasonic waves of higher ultrasonic frequency level in the cleaning solution. It should be noted that the ultrasonic waves may be generated of a pre-defined ultrasonic frequency level to operate the clothes pre-washing device 100 at the pre-defined ultrasonic frequency level based on a selected washing mode of the delicate washing mode, the normal washing mode, and the strong washing mode.

[0036] Further, the washing tank 202 may include the set of ultrasonic sensors present at the periphery of the washing tank 202. The set of ultrasonic sensors may be integrated with the ultrasonic transducer. For example, suppose a set of ten ultrasonic sensors (e.g., an ultrasonic sensor 502) may be coupled to the washing tank 202. For example, two ultrasonic sensors may be present on a front wall of the washing tank 202, two ultrasonic sensors on a back wall of the washing tank 202, two ultrasonic sensors on a bottom wall of the washing tank 202. Further, two ultrasonic sensor may be present on each side wall of the washing tank 202. It should be noted that each of the set of ten ultrasonic sensors may be present on an outer surface of the washing tank 202 and may be covered via the outer casing 104. Further, each of the set of ten ultrasonic sensors may include an ultrasonic transducer 504. In other words, a set of ten ultrasonic sensors may be integrated with a corresponding ultrasonic transducer of a set of ten ultrasonic transducers (e.g., the ultrasonic transducer 504) and are present on the periphery of the washing tank 202.

[0037] The set of ten ultrasonic sensors may be configured for generating the ultrasonic waves to create the cavitation bubbles in the cleaning solution. In particular, each of the set of ten ultrasonic sensors in conjunction with the corresponding ultrasonic transducer may be configured to generate ultrasonic waves which are sound waves with high frequency, in the cleaning solution. In other words, each of the set of ten ultrasonic sensors may be configured to generate ultrasonic vibration in the cleaning solution through mechanical energy coming from the corresponding ultrasonic transducer. Further, the set of ten ultrasonic sensors may be positioned in a way that ensures the clothes within the washing tank 202 are exposed to the ultrasonic waves from multiple directions and no blind spots areas are left within the washing tank 202 during the cleaning process. In an embodiment, the ultrasonic transducer 504 may be a piezoelectric ultrasonic transducer which converts electric energy into mechanical energy. The main advantage of using the piezoelectric ultrasonic transducer is their energy efficiency. This is due to direct conversion of the electrical energy into the mechanical energy, predominantly through lead zirconate titanate (PZT) or barium titanate materials. Energy loss from this conversion is minimal. Thus, around 95% of power generated using an ultrasonic generator (not shown) may be utilized for the cleaning process due to the direct conversion, resulting in an overall efficiency of the piezoelectric ultrasonic transducer approximately to 70% in any ultrasonic cleaning device.

[0038] In an embodiment, the ultrasonic generator may be coupled to the washing tank 202. Further, the ultrasonic generator may be configured to convert electric power into electrical signals to activate each of the set of ten ultrasonic transducers for generating the ultrasonic waves. In an embodiment, for effectively cleaning clothes (e.g., baby clothes), the ultrasonic generator may be configured to energize each of the set of ten ultrasonic transducers to generate the ultrasonic waves of higher ultrasonic frequency level (e.g., ranging between 60 kilohertz (kHz)-80 kHz). This may generate smaller cavitation bubbles for milder oscillations and implosions, effectively removing microscopic particles of the stains or the dirt, without causing damage to the clothes. As will be appreciated each of the set of ten ultrasonic sensors and the ultrasonic generator may be covered via the outer casing 104.

[0039] It should be noted that the cleaning solution may be nothing but a mixture of the fabric cleaning product and water. The mixture not only affects stains removal but also alters properties of the cleaning solution such as vapor pressure, surface tension, density, and viscosity, all of which influence vibration propagation and formation of cavitation bubbles during the cleaning process. Higher vapor pressure facilitates formation of the cavitation bubbles with less power input yet results in reduced energy absorption and release. In addition, elevated surface tension demands more energy for formation of the cavitation bubbles but enables greater energy storage within the cavitation bubbles. Further, circuit boards 506 (also referred to as electronic control boards) may be coupled to the washing tank 202. As already known to the person skilled in art, the circuit boards 506 may act as a central control unit that is configured for operating the washing tank 202.

[0040] Further the washing tank 202 may include the at least one inlet port. By way of an example, as depicted via the present FIG. 5, the at least one inlet port may correspond to a set of four inlet ports. The set of four inlet ports may include a pair of inlet ports 508 and a pair of inlet ports 510. The pair of inlet ports 508 may be present on a top edge of the back wall. In addition, the pair of inlet ports 510 be present on a bottom edge of the front wall. In an embodiment, each of the set of four inlet ports may receive water from a water inlet port (same as the water inlet port 302) of the clothes pre-washing device 100. Further, each of the set of four inlet ports may be controlled via the one or more pumps of the set of pumps. The set of pumps are configured for recirculating the cleaning solution within the washing tank 202 via the pumping technique. In an embodiment, the set of pumps may correspond to a set of two pumps (e.g., an exemplary pump 512). The pair of inlet ports 508 may be controlled via one pump of the set of two pumps and the pair of inlet ports 510 may be controlled via another pump of the set of two pumps. One pump near the pair of inlet ports 508 and the another pump near the pair of inlet ports 510 may recirculate the cleaning solution within the washing tank 202 to impart cycling wave effect for effective distribution of the ultrasonic waves and in turn to ensure maximum exposure of the cavitation bubbles to the clothes. As will be appreciated, each of the set of two pumps may be covered via the outer casing 104 of the clothes pre-washing device 100.

[0041] Further, the washing tank 202 may include the outlet port 204. The outlet port 204 may be coupled to the pipe. Further, the pipe outlet may be connected to a drainage port (same as the drainage port 304) present on the left side opposite the water inlet port. It should be noted that the drainage port may be present on the bottom edge of the back portion of the clothes pre-washing device 100.

Further, an outlet of the flexible pipe may be connected to the drain area to dispose of at least one of the residual particles or the cleaning solution.

[0042] Further, the washing tank 202 may include a heating system 514. The heating system 514 may be for heating the cleaning solution to a pre-defined temperature level based on the selected washing mode and the selected hygiene mode. As will be appreciated, a temperature of the cleaning solution significantly influences amount and intensity of the cavitation bubbles by altering properties of the cleaning solution. Increase in the temperature raises vapor pressure while reducing surface tension, viscosity, and density, fostering increased cavitation bubbles activity. Moreover, higher temperature enhances chemical activity, facilitating more efficient removal of the stains, dirt, and the micro-organisms from the clothes like those soiled with pee, poop, food, vomit, etc. Further, higher temperature improves mass transport that further aids in dispersing and dissolving dirt particles, enhancing overall cleaning process. In addition, a ventilation fan 516 may be coupled to the washing tank 202. The ventilation fan 516 may be configured for assisting in dissipation of heat generated during the cleaning process, preventing overheating, and ensuring optimal performance and longevity of the clothes pre-washing device 100.

[0043] Referring now to FIG. 6, a cross-sectional side view 600 of the washing tank 202 is illustrated, in accordance with some embodiments of the present disclosure. FIG. 6 is explained in conjunction with FIGS. 1, 2, 3, 4, and 5. The cross-section side view 600 depicts a side view of the clothes pre-washing device 100.

As depicted via the cross-sectional view 600, each ultrasonic sensor may be configured for generating the ultrasonic waves of the pre-defined ultrasonic frequency level (i.e., of higher frequency). The ultrasonic waves may be generated to create cavitation bubbles (e.g., an exemplary cavitation bubble 604). The created cavitation bubbles may be smaller in size to easily remove the stains and the dirt from the clothes. Further, the small cavitation bubbles may be configured to implode on the clothes for removing the stains and dirt particles present on the clothes.

[0044] Further, the set of pumps associated may be associated with each of the at least one inlet port. As already explained in FIG. 5, each of a pair of inlet ports (i.e., the pair of inlet ports 508 and the pair of inlet ports 510) may be associated with a pump (e.g., the exemplary pump 512) of the set of two pumps. The pump may be configured to control each of the pair of inlet ports. Further, each pump may circulate the cleaning solution within the washing tank 202 as depicted via single arrows and circular arrows. The cleaning solution may be recirculated to effectively distribute the cavitation bubbles within the washing tank 202 to tackle blind spots. On completing the cleaning process, the outlet port 204 may be configured to drain out at least one of the residual particles and the cleaning solution through the pipe (e.g., an exemplary pipe 606). Further, the pipe outlet of the exemplary pipe 606 may be connected to the drainage port 304. The drainage port 304 may be further connected to the flexible pipe and the outlet of the flexible pipe may be connected to the drain area.

In some embodiments, these options on, off, start, pause may be the visual indication itself and will get illuminated upon selection.

[0055] Referring now to FIG. 8, a method 800 of operating the clothes pre-washing device 100 is depicted via a flowchart, in accordance with some embodiments of the present disclosure. FIG. 8 is explained in conjunction with FIGS. 1, 2, 3, 4, 5, 6, and 7. At step 802, a user selection corresponding to one or more actions may be received. The one or more actions may be associated with the clothes pre-washing device 100. In an embodiment, the one or more actions may include powering the clothes pre-washing device 100, selecting a washing mode, selecting a hygiene mode, selecting an ultraviolet storage mode, and selecting one of a start option or a pause option for the clothes pre-washing device. In an embodiment, the washing mode may include one of a delicate washing mode, a normal washing mode, and a strong washing mode. Further, the hygiene mode may include one of an antibacterial hygiene mode, an odor removal hygiene mode, and a deep sanitization hygiene mode. With reference to FIG. 7, the user may perform the one or more actions via the set of buttons 306 present on the interactive display. To perform the one or more actions, initially, the user of the clothes pre-washing device 100 may place the clothes for pre-washing in the washing tank 202 by opening the top lid 102 of the clothes pre-washing device 100. Further, after placing the clothes, the user may close the top lid 102 to cover the washing tank 202.

[0056] Upon placing the clothes in the washing tank 202 the user may add at least one of the fabric cleaning product, the fabric softening product, or the fabric sanitizing product in the feeding tray 108 in a corresponding section of the set of sections. By way of an example, consider a scenario, where the user may want to pre-wash his infant clothes to remove stains of vomit, poop, etc., and kill any micro-organisms present on the clothes to disinfect the clothes for next use. In this scenario, once the user places the clothes within the washing tank 202, the user may turn on the clothes pre-washing device 100 using the power button 702 upon connecting the power cord to the power port. Further, based on a type of the stains, the user may select an appropriate washing mode, e.g., the normal washing mode using the wash mode button 704. In addition, for disinfecting the clothes, the user may select an appropriate hygiene mode, e.g., the antibacterial hygiene mode using the hygiene mode button 706. Further, the user may turn off the ultraviolet storage mode using the UV storage button 708 as he might not be interested in storing the clothes within the washing tank 202 after the cleaning process. Lastly, the user may start the cleaning process using the cycle button 710.

[0057] Further, upon receiving the user selection, each of the at least one inlet port may be configured to dispense a pre-defined amount of water as per the selected washing mode. In addition to dispensing the pre-defined amount of water, one or more inlet ports of the at least one inlet port may dispense the fabric cleaning product along with the pre-defined amount water to obtain the cleaning solution. The obtained cleaning solution may reach the pre-defined temperature level based on the selected washing mode and the selected hygiene mode. In continuation to the above example, for the normal washing mode, the range of the pre-defined temperature level of the cleaning solution may be between 30 to 35 degrees, and the range of the pre-defined ultrasonic frequency level may be between 40 to 45 kHz.

[0058] Further, in response to receiving the user selection, at step 804 a cleaning process may be initiated. To initiate the cleaning process, at step 806, ultrasonic waves may be generated in the cleaning solution. The ultrasonic waves may be generated to create cavitation bubbles in the cleaning solution within the washing tank 202. As will be appreciated, the ultrasonic waves may be generated by the ultrasonic transducer using each of the set of ultrasonic sensors. This has been already explained in FIG. 5. It should be noted that the ultrasonic waves may be generated of the pre-defined ultrasonic frequency level based on the selected washing mode. It should be noted that each of the selected washing mode and the selected hygiene mode may be configured to operate for the pre-defined amount of washing mode cycle time and the pre-defined amount of hygiene mode cycle time.

[0059] In addition to generation of the ultrasonic waves, at step 808, the cleaning solution may be recirculated within the washing tank 202 via the pumping technique. It should be noted that the cleaning solution may be circulated via the set of pumps. Further, at step 810, a completion of the cleaning process may be detected. Upon detecting the completing of the cleaning process, at step 812, at least one of residual particles or the cleaning solution may be drained. In an embodiment, the at least one of residual particles or the cleaning solution may be drained via the outlet port 204.

[0060] Further, after draining the residual particles and the cleaning solution, a pre-defined amount clean water may be dispensed based on the selected washing mode via each of the at least one inlet port. In some embodiments, in addition to the pre-defined amount of clean water, the fabric softening product and the fabric sanitizing product may be dispensed via the one or more inlet ports based on user requirement. Further, a mixture of the pre-defined amount of clean water including the fabric softening product and the fabric sanitizing product may be dispensed. Further, the ultraviolet-C light integrated on the top lid 102 of the washing tank 202 may be enabled for killing micro-organisms based on the selected hygiene mode.

[0061] As will also be appreciated, some of the above-described techniques may take the form of computer or controller implemented processes and apparatuses for practicing those processes.
