As the snow ice ice maker has improved its performance and the user layer has become thicker, the ice maker has encountered a new technical problem that meets the demands of new consumers.

Specifically, the snow ice ice maker has been used as a facility for providing cold beverages such as ice water, slush beverage, and soft drink by freezing a solution containing various edible materials such as milk sugar, juice, etc. in a frozen state.

As a result, one of the newly emerging problems is to keep the cleanliness suitable for hygiene while de-icing materials containing organic substances such as milk, sugar, and juice. If the water containing a large amount of organic matter is frozen as described above, it is difficult to maintain the cleanliness of the rotating ice-making drum. Particularly, in a hot and humid environment in summer, organic matter deposited on a rotating ice drum is decomposed in a short period of time if it is used again without removing organic residue such as milk or sugar remaining in the ice maker. If these spoilage bacteria are left untouched, their seriousness and danger will be great.

8, a cleaning device 200 is further provided to clean the ice-making drum 10 on the ice-making drum 10. [ 8, the washing apparatus 200 includes a drainage drain 206 installed at the bottom of the ice container 65, a steam generator 220 installed at an upper portion of the ice making drum 10, A washing water pump 280 for supplying washing water to the steam generator 220 and a washing switch connected to the microcomputer 101 to provide the washing signal s1, (201).

8 to 12, a cleaning nozzle 221 of the cleaning apparatus 200 is installed on the spray plate 210 at an upper portion of the ice-making drum 10. As shown in FIG. The heated water and water vapor supplied from the steam generator 220 through the spray pipe 223 are sprayed onto the surface of the ice-making drum 10 rotated by the cleaning nozzle 221. The cleaning nozzles 221 are provided in a plurality of positions corresponding to the length of the ice-making drum. The installation interval is 3 to 5 cm and can be installed more densely or as rarely as required. In the embodiment, the installation interval is about 4 cm.

The ice-making receptacle 70 installed between the ice-making drum 10 and the ice container 65 can be easily separated from the cabinet during the cleaning process. The inner side frame 271 of the ice-making receptacle 70 is inserted into the groove 272 provided in the frame F to support the inside of the container and at the same time the support plate 273 is extended outside the ice- And fixed to the iron plate of the ice-maker frame (F) by the magnet (274).

To remove the ice-making receptacle 70, the magnet 274 at the end of the support plate 273 is taken out of the iron plate frame F and pulled forward. At this time, the inner frame 271 comes out of the groove 272, and thus the ice-making receptacle 70 is separated from the frame. The assembly is done in reverse order of the separation process and is very simple.

The washing water pump 280 is connected to the microcomputer 101 so as to open and close the driving current through the driving driver 280s controlled by the washing water pump control signal c2. The control signals are either a high-low signal or a byte-sized data signal.

The steam generator 220 includes a water inlet pipe 222 for receiving water from the washing water pump 280 to the heating chamber 224 and a water inlet pipe 222 for supplying water and steam heated in the heating chamber to the washing nozzle 221 And the spray tube 223 is connected. The electric heater 230 is embedded in the heating chamber 224. The electric heater 230 heats the water supplied through the water inlet pipe 222. The heated hot water or water vapor is supplied to be sprayed from the cleaning nozzle 221 through the spray pipe 223. The electric heater 230 is incorporated in the steam generator 220 together with the temperature sensor 231 connected to the microcomputer 101 and providing the temperature signal s2 to the microcomputer 101. [

The electric heater 230 receives a driving current AC through a heater switch 232 and a temperature fuse 233 which are opened and closed as a heater control signal c3 of the microcomputer 101 in order to maintain a set temperature, . Thus, the electric heater 230 maintains the set temperature range. Specifically, the microcomputer 101 detects the detected temperature of the temperature sensor 231 as the temperature signal s2 while driving the electric heater 230, and performs control for maintaining the set temperature. As an example, when the temperature exceeds 400 ° C, the heater switch 232 is controlled to be in the power off state and the heater switch 232 is controlled to be in the power on state when the temperature is lowered again. This set temperature can be used within the range of 300 to 500 占 폚. The temperature fuse 233 is connected to the electric current supply circuit of the electric heater in series, so that the temperature fuse 233 is short-circuited in the abnormal overheat state to block the drive current, thereby preventing an accident caused by overheating .

12, the washing water pump 280 is connected to the microcomputer 101 so that the driving current is opened or closed through the driving driver 280s controlled by the control signal c2. When the washing water pump 280 is driven, the washing water 281 is supplied to the heating chamber 224 along the inlet pipe 222 so that the water passing through the heating chamber flows along the inlet pipe 223 from the nozzle 221 It becomes an eruption. At this time, since the electric heater 230 is being driven, the water is heated in the heating chamber 224, and the water is ejected into the heated water and steam. The temperature of the heated water is preferably heated to 85 DEG C or higher so as to maintain the washing and sterilizing action. This temperature can be increased or decreased depending on the setting of the heater temperature.

The control of the washing water pump 280 by the microcomputer 101 can increase the cleaning efficiency of the ice-making drum 10 by controlling the intensity of driving the washing water pump. If the amount of water supplied to the heating chamber 224 is large, the water is not vaporized in the heating chamber 224 at all, so that a large amount of water is sprayed from the cleaning nozzle 221. If the amount of water to be supplied to the heating chamber 224 is moderately low and the electric heater 230 is hot at a sufficient heating temperature, all the water is converted into hot steam and hot water vapor is vigorously sprayed from the cleaning nozzle 221. By using this action, the microcomputer 101 controls the intensity of the driving current of the washing water pump 280 so that water can be sprayed from the nozzle, steam can be sprayed, or water and water vapor can be sprayed together.

Specifically, during the cleaning time of the ice-making drum 10, the water is primarily sprayed from the cleaning nozzle 221, then the water is mainly sprayed, and then the water is sprayed, Thereby maximizing the efficiency of cleaning and disinfection of the ice-making jig 10. The control of the wash water pump 280 in the above-described three stages is performed by operating time of 10 seconds each when the washing time is 30 seconds in the embodiment.

In order to prevent the cleaning process from being performed in a state where the ice-making receptacle 70 is assembled, the ice-making receptacle 70 is assembled into a structure that can be separated from the frame F. An ice-making receptacle detection switch 211 is provided on the ice-maker frame F so that the washing operation can not be performed in a state where the ice-making receptacle 70 is assembled, and the ice-maker receptacle detection signal s3 is connected to the microcomputer 101 So that the microcomputer 101 can refer to it.

The microcomputer 101 of the control unit 100 is further programmed as shown in FIG. 13 so as to execute the following washing control (II) on the main word I of the ice maker shown in FIG.

Alternatively, if the signal is a switch-on signal, the ice-maker receptacle detection switch 211 is checked again, and if the ice-maker receptacle detection signal s3 is switched on, the controller returns to the main controller I loop. On the other hand, if the ice-making receptacle detection signal s3 is switched off, the washing control II is called and executed.

The microcomputer provides the heater control signal c3 to the heater switch 232 to drive the heater 230 in the loop of the cleaning control II. And supplies the wash water pump control signal c2 to the drive driver 280s to drive the wash water pump 280. [ And the ice-making drum control signal c1 is supplied to the drive driver 90s to drive the ice-making drum 10. [ In addition, the control signal c4 is provided to the drain valve 207 of the drain drain 206 to open the drain valve 207.

In this state, the heated water and water vapor in the washing nozzle 221 are sprayed on the rotating ice drum 10 to be cleaned and sterilized, so that the water used for washing can be drained from the drain drain 206 . In this way, the cooling function is not called but the heated water and steam are sprayed on the rotating ice-making drum 10 which is rotated, and the water sprayed on the ice-making drum 10 is drained by the drain while the heat is sterilized by washing with hot water and steam. The execution time of the washing control is 20 to 60 seconds. The fastest is 20 seconds. When the washing time has elapsed, the microcomputer 101 supplies the heater control signal c3 to the heater switch 232 to stop the driving of the electric heater 230 and the washing water pump control signal c2 to the driving driver 280s, And stops the driving of the washing water pump 280 and stops the driving of the ice-making drum 10 by providing the ice-making drum control signal c1 to the driving driver 90s.

At this time, the drainage drain 206 is opened as it is to drain all remaining water. The microcomputer 10 supplies the control signal c4 to the drain valve 207 of the drain drain 206 to close the drain valve 207. [ In this process, the cleaning process is terminated and control returns to main routine (I).
