Sterilizer for autonomous robotic cleaner

Abstract

A sterilizer for an autonomous robotic cleaner is revealed. An ultraviolet (UV) sterilizer is disposed on a top surface of an autonomous robotic cleaner. When the autonomous robotic cleaner is moved for cleaning the floor, consumers can activate the UV sterilizer by remote control to perform sterilization of indoor environments according to their needs. Thus a clean and hygienic environment is achieved. A person or pet in area to be cleaned is detected in a real time manner by a thermal sensor module so that the UV sterilizer is turned off immediately to protect the person or pet from injuries caused by exposure to UV light.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(5) Refer to FIG. 1, FIG. 2 and FIG. 3, a sterilizer for an autonomous robotic cleaner according to the present invention is an ultraviolet (UV) sterilizer 2 disposed on a top surface 11 of a main body of an autonomous robotic cleaner 1. The UV sterilizer 2 is composed of a suction mount 21, a control module 22, a power supply module 23, an ultraviolet (UV) generator 24, and a thermal sensor module 25.

(6) The suction mount 21 consists of a mount 211 and at least one suction cup 212. In the embodiment shown in FIG. 2 and FIG. 3, three suction cups 212 are arranged at the bottom of the mount 211 so that the mount 211 is mounted and fixed on the top surface 11 of the main body of the autonomous robotic cleaner 1 by the suction cups 212 attached to the top surface 11 of the main body. The control module 22, the power supply module 23, the UV generator 24, and the thermal sensor module 25 are all disposed on the suction mount 21.

(7) The control module 22 is electrically connected to the power supply module 23, the UV generator 24, and the thermal sensor module 25 while the power supply module 23 supplies power to the control module 22, the UV generator 24, and the thermal sensor module 25. The control module 22 is operated to drive the UV generator 24 to produce UV light for sterilization of indoor spaces.

(8) The thermal sensor module 25 is used for detecting whether there is a person or animal in a space to be cleaned and sending messages related to detection results to the control module 22. Under the condition that the UV generator 24 emits UV light for sterilization and disinfection, the control module 22 checks whether there is a person or animal in the space to be cleaned according to the messages from the thermal sensor module 25. When the control module 22 checks that there is no person or animal in the space to be cleaned, the UV generator 24 keeps current state under control of the control module 22. Once the control module 22 checks that there is a person or animal in the space to be cleaned, the control module 22 controls the UV generator 24 to stop working.

(9) In a preferred embodiment, the UV sterilizer 2 further includes a display module 26 which is electrically connected to the control module 22 and the power supply module 23. The power supply module 23 provides power to the display module 26 while the control module 22 includes a power usage monitor unit 221 which is used for detecting power usage of the power supply module 23 and sending detected values of the power usage to the display module 26 to be displayed.

(10) In a preferred embodiment, the control module 22 further includes a time setting unit 222 which is used to set on and off time of the UV generator 24 and the set on and off time of the UV generator 24 is shown on the display module 26. Users can set on and off time of the UV generator 24 by the control module 22 and the time being set is displayed on the display module 26. For example, the user can set the time the UV generator 24 will be activated and inactivated such as one day in each month, one day in each week, or a moment in each day. When the time being set is coming and the control module 22 checks that there is no person or animal in the space to be cleaned according to detection results from the thermal sensor module 25, the control module 22 of the UV sterilizer 2 activates the UV generator 24 to emit UV light for disinfection and sterilization of the space to be cleaned.

(11) In a preferred embodiment, the UV sterilizer 2 further includes a wireless network communication module 27 which is fixed on the suction mount 21 and electrically connected to the control module 22 and the power supply module 23. The power supply module 23 supplies power to the wireless network communication module 27 which receives signals from an intelligent electronic device (IED) 3 with network connection capabilities and sends the signals to the control module 22. Thus users can remotely control the UV sterilizer 2 to turn on or turn off the UV generator 24 for UV sterilization by operating and executing a software program of the TED 3. It should be noted that the UV generator 24 only starts to emit UV light for sterilization when the thermal sensor module 25 sends detection results to the control module 22 and the control module 22 checks that there is no person in the space to be cleaned according to the detection results received. The intelligent electronic device (IED) 3 with network connection capabilities can be a wireless communication device such as a mobile phone, a tablet, a computer, etc.

(12) Once receiving a signal for activating the UV generator 24 from the intelligent electronic device (IED) 3 with network connection capabilities, the wireless network communication module 27 sends the signal to the control module 22 and the UV generator 24 produces UV light for sterilization after the control module 22 checking that there is no person in the space to be cleaned according to the signal received.

(13) Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details, and representative devices shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalent.
