Of course, both the positive electrode 83 and the negative electrode 84 are connected to the controller 70, the supply of power is controlled, and eventually the operation of the sterilizer 80 as a whole is controlled.

Hereinafter, the operation of the ice maker with the sterilization device configured as described above and its operation mode will be described in detail.

Referring to the normal ice-making operation of the ice maker according to the present invention, first, the water supply pipe 42 is connected to the water pipe 41, the drain pipe 60 is connected to the drain and installed, then turn on the power (ON) controller 70 When the compressor 22, the condenser 24 and the condenser fan 26 of the refrigeration cycle device 20 are controlled and operated, the water supply control valve 44 of the water supply device 40 is opened to supply water. , The water supplied through the water supply pipe 42 flows evenly in the support plate 35 and falls down through the water supply hole 36 to be stored in the water storage tank 34.

When the ice making water is sufficiently stored in the reservoir 34, the controller 70 shuts off the water supply control valve 44 to stop the water supply and simultaneously operates the pump 54 of the ice making water supply device 50. The ice-making water in 34 is sent to the spray nozzle 58, and the spray nozzle 58 injects the ice-making water into the ice-making frame 31. As shown in FIG.

When the injection of the ice-making water by the spray nozzle 58 is continued, ice-making is started from the inside of the ice-making frame 31, and after the ice-making, that is, ice-making is completed, the controller 70 of the ice-making water supply apparatus 50 At the same time as the operation of the pump 54 is stopped, hot gas is supplied to the evaporator 28 through a bypass line (not shown) directly connected to the evaporator 28 from the compressor 22 of the refrigerating cycle apparatus 20.

At the same time, when water is supplied to the upper portion of the support plate 35 by opening the water supply control valve 42 of the water supply pipe 42, the water flows into the reservoir 34 while melting ice iced on the support plate 35. At this time, by operating the pump 54 once or twice to apply ice to the ice making frame 31 through the injection nozzle 58, the remaining ice in the ice making frame 31 can be removed.

The ice removed or dropped from the ice making frame 31 as described above slides along the inclined grill 32, passes through the discharge door 33, and is stored in the ice storage chamber 16, and the water is stored in the reservoir 34.

Of course, after that, the water supply control valve 44 is again blocked by the controller 70 to stop the supply of water, and the refrigerant gas is condensed in the condenser 24 and supplied to the evaporator 28 while the pump 54 is operated to store the water tank. The ice-making water of 34 is sprayed into the ice-making frame 31 by the spray nozzle 58 to repeat ice-making.

In particular, according to one feature of the present invention, the sterilizing apparatus 80 may be used to sterilize the ice making water or clean the ice maker as a whole.

That is, in the normal ice making operation, the controller 70 applies power to each of the electrodes 83 and 84 of the sterilization device 80 to sterilize water containing silver ions through electrolysis of the water supplied from the water supply pipe 42. Create Here, the water supplied from the water supply pipe 42 is introduced into the body 82 through the inlet port 81, so that silver ions are generated by electrolysis by the respective electrodes 83 and 84 formed of silver. The generated silver ions are included in the ice making water to disinfect the ice making water. In this case, of course, water may be supplied through the water supply pipe 42 to be used as ice making water.

Meanwhile, the ice maker may be sterilized and cleaned by using the controller 70 automatically or by operating the controller 70 after using the ice maker for a predetermined time or when desired by the user.

In more detail, after a certain period of time or when the user wants to clean the ice maker completely, the controller 70 automatically or by operating the controller 70 to first stop the operation of the ice-making water supply device 50. In order to stop the ice making operation in the ice making room 30, all the ice of the ice making room 30 and the ice storage room 16 is removed or taken out (S100).

When all the ice in the ice maker is removed, water is supplied to the ice making chamber 30 and the ice storage chamber 16 through the water supply pipe 42 of the water supply device 40 to wash the ice making chamber 30 and the ice storage chamber 16. (S102).

When the washing is completed, the water supply pipe 42 of the water supply device 40 is blocked, and the opening and closing valve 64 of the drain pipe 60 is opened to discharge the washing water to the outside of the ice maker through the drain hole 62 (S104).

After draining the washing water completely, the drain hole 62 is closed by using the opening and closing valve 64 of the drain pipe 60, and the opening and closing valve 86 provided in the inlet port 81 of the sterilization device 80 and At the same time by operating the sterilization device 80, the sterilizing water is supplied to the ice making room 30 and the ice storage room 16 to clean and sterilize for a predetermined time (S106).

After the cleaning and sterilization of the ice making chamber 30 and the ice storage chamber 16 are completed, the operation of the sterilizing device 80 is stopped, the closing valve 86 is closed, and the opening and closing valve 64 of the drain pipe 60 is opened. By discharging the waste water after cleaning and sterilization through the drain hole 62 (S108).

When the discharge of the waste water is completed, both the water supply control valve 42 of the water supply device 40 and the opening / closing valve 86 of the sterilization device 80 are opened to rinse the rinsing water into the ice making room 32 and the ice storage room 16. The supply is finally rinsed in the ice making chamber 30 and the ice storage chamber 16 (S110).

Thereafter, the water supply control valve 42 of the water supply device 40 and the control valve 86 of the sterilization device 80 are all closed, and then the open / close valve 64 of the drain pipe 60 is discharged to disinfect the rinsing water. And to complete the cleaning (S112).

Optionally, according to another embodiment of the present invention, the rinsing step S110 and the sterilization and cleaning completion step S112 may be performed simultaneously. That is, in the state in which the discharge of the waste water is completed (S108), both the water supply control valve 42 and the open / close valve 86 of the sterilization device 80 are opened to open the ice making room 32 and the ice storage room. The rinsing water is supplied to (16) to finally rinse the ice making chamber 30 and the ice storage chamber 16, and at the same time, the opening and closing valve 64 of the drain pipe 60 is discharged to discharge the rinsing water to complete sterilization and cleaning. You can do it.

Of course, when the cleaning is completed, it is possible to perform ice making by keeping the ice maker in the normal state as described above.

As a result of experiments on sterilization after cleaning the ice maker using the sterilizer as described above, when the bacteria were cultured and measured in the ice-water storage tank of the ice-making room without the sterilizer operated, 20,000 bacteria / ml Was detected, but after the sterilization device was operated to mix the sterilized water containing silver ions, after 10 minutes, 4 mice / ml were detected, and the sterilizer was operated to mix the sterilized water containing silver ions. 2 minutes / ml were detected after the passage of minutes, but, of course, no E. coli and S. coli were detected at each measurement.

As can be seen from the above table, in the ice maker according to the present invention, the general bacteria generated or parasitic in the ice-making water reservoir have been markedly reduced or almost all sterilized by the sterilized water containing silver ions.

Therefore, ice makers, in particular, can be cleaned by completely sterilizing the ice-making water reservoir in which the most propagation or maintenance of bacteria and foreign substances can always be supplied with hygienic and safe ice-making water.

While a preferred embodiment according to the present invention has been described above, it will be understood by those skilled in the art that various modifications and changes can be made without departing from the scope of the appended claims.
