(10) Dispenser with an Integral Control Switch for Discharging Water and Ice on Refrigerator

(11) FIG. 2 illustrates a side cross-sectional view of the configuration of an exemplary dispenser installed on a refrigeration equipment in accordance with an embodiment of the present disclosure. FIG. 3 illustrates an exemplary dispenser structure with an integral lever hingedly coupled through a shaft in accordance with an embodiment of the present disclosure. FIG. 4 illustrates a structural view of the exemplary dispenser for refrigeration equipment in accordance with an embodiment of the present disclosure.

(12) Referring FIG. 2, a dispenser is installed on the exterior side of the front door of the refrigeration equipment (not explicitly shown). The dispenser is operable to dispense water from a water purifier and ice from an ice maker in the refrigeration equipment, e.g., when the front door is closed. A cavity is formed in the main body 202 of the dispenser and directs to the inner side of the door. In the cavity, an ice discharge port 204, an ice guide 206, a water discharge port 208, an integral lever 210, a first and a second switches 212, 216, a first and a second restoring members 214, 218 may be installed. An ice maker may, for example, be disposed on the inner side of a door of the refrigeration equipment.

(13) The ice discharge port 204 is disposed on one side (e.g., inside the cavity) of the main body 202 and is capable of discharging ice produced in the refrigeration equipment to the outside. The ice discharge port 204 may include the ice guide 206 installed at the tip (or the end) which is a protruding member that extends from the main body of the ice guide 206.

(14) The water discharge port 208 may be installed on the other side (e.g., outside the cavity) of the main body 202 for discharging water from the water purifier that is disposed inside the refrigeration equipment (not shown).

(15) As shown in FIGS. 3 and 4, an assembling hole 206a may be formed at the lower end of the ice guide 206 which is rounded and protrudes downward in this example. A shaft 207 is inserted into the assembling hole 206a for hingedly couple the integral lever 210 to the ice guide 206. In this example, a middle portion of the integral lever 210 is hingedly coupled with the assembling hole 206a of the ice guide 206 so it can pivot vertically. In FIG. 3, reference numeral 211 represents a through hole on the integral lever 210 for ice to fall through when it comes from the ice guide 206.

(16) In this embodiment, one end (e.g., the upper end) of the integral lever 210 can pivot in the vertical direction through the hinge coupling and is configured as a water discharge button 210a for discharging water. The other end (e.g., the lower end) is configured as an ice discharge button 210b for discharging ice.

(17) The water discharge button 210a includes the first switch 212 and the first restoring member 214 that are disposed on the back side of the ice guide 206. The first switch 212 can detect an external pressure applied thereto (e.g., by a user) and generate a signal instructing to open the water discharge port 208. The first restoring member 214 can automatically restore the integral lever 210 to the relaxed state when the external pressure is released. For instance, the first restoring member 214 may include a spring structure.

(18) Similarly, the ice discharge button 210b includes the second switch 216 and the second restoring member 218 disposed on the back side of the wall surface inside the cavity. The second switch 216 can detect an external pressure applied thereto (e.g., by a user) and generate a signal instructing to open the ice discharge port 204. The second restoring member 218 restores automatically the position of the integral lever 210 to the relaxed state when the external pressure is released. The second restoring member 218 may be, for example, a spring structure.

(19) Herein, the first switch 212 and the first restoring member 214 may be collective referred to as a water discharge sensing element; and the second switch 216 and the second restoring member 218 may be collectively referred to as an ice discharge sensing element.

(20) In this example, the integral lever 210 interlocks with the first and second switches 212, 216. The first and second restoring members 214, 218 may be coupled to the main body 202 of the dispenser. For instance, the assembly process can be as follows.

(21) (1) Providing the main body 202 of the dispenser having the ice discharge port 204 and the water discharge port 208 formed therein;

(22) (2) Assembling the ice guide 206 at the end (tip portion) of the ice discharge port 204;

(23) (3) Assembling the switch and the spring structure to the predetermined location of one side of the ice guide 206 and to the predetermined location of one side of the main body 202 of the dispenser respectively; and

(24) (4) Coupling the integral lever 210 to the protruding lower end of the ice guide 206 by using a hinge.

(25) As a result, when a user presses the water discharge button 210a interlocked with the first switch 212 disposed on the back side of one end of the integral lever 210, water can be discharged to the outside of the refrigeration equipment through the water discharge port 208. Upon the user releasing the water discharge button 210a, the position of the integral lever 210 is restored automatically to the original position by the first restoring member 214, and then water dispensing is stopped.

(26) Similarly, upon a user pressing the ice discharge button 210b interlocked with the second switch 216 disposed on the back side of the other end of the integral lever 210, the user may dispense ice from the refrigeration equipment through the ice discharge port 204 and the ice guide 206. When the user releases the ice discharge button 210b, the position of the integral lever 210 is restored automatically to the original position by the second restoring member 218. At the same time, ice discharging from the ice discharge port 204 is stopped.

(27) FIG. 5 is a block diagram of circuitry coupled to an exemplary dispenser on a refrigeration equipment in accordance an embodiment of the present disclosure. The circuitry may include a first sensing unit 502, a second sensing unit 504, a first opening and closing execution unit 508, and a second opening and closing execution unit 510.

(28) Referring to FIG. 5, the first sensing unit 502 may correspond to, for example, the first switch 212 shown in FIG. 2, and operate to send a signal to the control unit 506 upon receiving a user instruction for dispensing water. Based on the signal, the control unit 506 controls the water discharge port 208 to open. Similar, when receiving a user instruction to stop dispensing water, the first sensing unit 502 can send a corresponding signal to the control unit 506.

(29) Similarly, the second sensing unit 504 may correspond to, for example, the second switch 216 shown in FIG. 2. Upon receiving a user instruction to dispense ice, the sensing unit 504 may operate to send a signal to the control unit 506 for opening the ice discharge port 204. Upon receiving a user instruction to stop dispensing ice, the second sensing unit 504 sends a corresponding signal to the control unit 506.

(30) The control unit 506 may be, for example, a microprocessor configured to control the operations of the refrigeration equipment. The control unit 506 is capable of generating a command for opening the water discharge port 208 and transmitting the command to the first opening and closing execution unit 508. When the first sensing unit 502 senses a release of the external pressure, the control unit is capable of generating a command for closing the water discharge port 208 and transmitting the command to the first opening and closing execution unit 508.

(31) Similarly, the control unit 506 can receive a sensed pressing signal from the second sensing unit 504 and accordingly generate an opening command to open the ice discharge port 204 and transmits the opening command to the second opening and closing execution unit 510. The control unit can receive a sensed release signal from the second sensing unit 504 and generate a closing command to close the ice discharge port 204 and transmits the closing command to the second opening and closing execution unit 510.

(32) The first opening and closing execution unit 508 may have multiple components, e.g., including a solenoid valve and a driving circuit. When an opening command is transmitted from the control unit 506, the first opening and closing execution unit 508 may operate to open the water discharge port 208. When a closing command is transmitted from the control unit 506, the first opening and closing execution unit 508 may operate to close the water discharge port 208.

(33) Similarly, the second opening and closing execution unit 510 may have multiple components, e.g., including a solenoid valve and a driving circuit. When an opening command is transmitted from the control unit 506, the second opening and closing execution unit 510 may operate to open the ice discharge port 204. When a closing command is transmitted from the control unit 506, the second opening and closing execution unit 510 may operate to close the ice discharge port 204.

(34) Hereinafter, an exemplary process for controlling operation of the dispenser will be described in detail with reference to the dispenser structure and the apparatus of operation control for refrigeration equipment having the configuration as described above in accordance with an embodiment of the present invention.

(35) FIG. 6 is a flow chart showing an exemplary process for controlling operation of a dispenser on a refrigeration equipment in accordance with the invention.

(36) Referring to FIG. 6, at 602, the control unit 506 monitors whether the water discharge button 210a or the ice discharge button 210b is pressed. The water discharge button 210a corresponds to one end of an integral lever 210 coupled pivotally to the ice guide 206 assembled at the tip of an ice discharge port 204, as described in greater detail above. The ice discharge button 210b is on the other end of the integral lever 210.

(37) To this end, when the water discharge button 210a is pressed, the first switch 212 generates a sensing signal of pressing to open the water discharge port 208 and transmits the sensing signal to the control unit 506. When the pressing of the ice discharge button 201b is sensed, the second switch 216 generates a sensing signal of pressing to open the ice discharge port 204 and transmits the sensing signal to the control unit 506.

(38) In other words, when the discharge button is pressed at 604, the control unit 506 determines whether the water discharge button 210a or the ice discharge button 210b is pressed, at 606 and 608.

(39) If it is determine the water discharge button 210a is pressed, the control unit 506 generates an opening command for discharging water and transmits the command to the first opening and closing execution unit 508. Consequently, the water discharge port 208 is opened by the first opening and closing execution unit 508. As a result, water is discharged from the refrigerator to the outside, at 610.

(40) At 612, the control unit 506 determines whether a sensing signal of releasing of pressing of the water discharge button 210a is input from the first switch 212. When the sensing signal of releasing is received, the control unit 506 generates a closing command to stop discharging water and transmits the command to the first opening and closing execution unit 508. As a result, the water discharge port 208 is closed by the first opening and closing execution unit 508. As a result, water dispensing is stopped. At the same time the position of the integral lever 210 is restored automatically by the first restoring member 214 at 614. In other words, the water discharge port 208 is opened to allow water to be discharged to the outside only when the water discharge button 210a is pressed.

(41) On the other hand, if it is determined at 608 that the pressing is for the ice discharge button 210b, the control unit 506 generates an opening command for discharging ice and transmits the command to the second opening and closing execution unit 510. As a result, the ice discharge port 204 is opened by the second opening and closing execution unit 510. As a result, ice is discharged to the outside of the refrigerator at 616.

(42) At 618, the control unit 506 determines whether a sensing signal of releasing of the ice discharge button 210b is input from the second switch 216. If yes, the control unit 506 generates a closing command to stop discharging ice and transmits the command to the second opening and closing execution unit 510. As a result, the ice discharge port 204 is closed by the second opening and closing execution unit 510. Thereby, ice discharging is stopped and the position of the integral lever 210 is restored automatically by the second restoring member 218 at operation 620. In other words, the ice discharge port 204 is opened to allow ice to be discharged to the outside only when the ice discharge button 210b is pressed.

(43) Although certain preferred embodiments and methods have been disclosed herein, it will be apparent from the foregoing disclosure to those skilled in the art that variations and modifications of such embodiments and methods may be made without departing from the spirit and scope of the invention. It is intended that the invention shall be limited only to the extent required by the appended claims and the rules and principles of applicable law.
