In order to execute the cleaning process, the ice-making receptacle 30 must be removed from the cabinet before execution of the cleaning control. The controller microcomputer 101 detects the state in which the icemaker 30 is separated from the frame by the microcomputer 101 by using the water level sensor 31 as the container detecting sensor 38 of the coupling device of the ice maker 30 do.

The coupling device of the ice-making receptacle 30 is connected to the microcomputer 101 in such a manner that the container detecting sensor 38 for detecting the ice-making receptacle 30 is mounted on the frame F so that the ice- In this case, the microcom can detect the assembled state or the separated state of the ice-making receptacle 30 as the state of the sensor 38.

The temperature quality of powder ice is sensitive to the temperature of the environment in which it is used. In spring and autumn temperatures, which are 25 ° C in temperature, the surface temperature of the ice drum is raised in the cold winter and the surface temperature of the ice drum is lowered in the hot summer. Also, since the cooling temperature of the ice-making drum is related to the ice-making time and the temperature of the ice, the temperature of the ice can be controlled by adjusting the temperature of the ice-making drum

The inventive powder ice ice maker drives the ice-making drum to induce the surface temperature of Table 1 on the basis of a 1-horsepower refrigerator, thereby managing the surface temperature of the ice-making drum and managing the temperature quality of the powder ice as the temperature management.

Surface temperature of ice drum / RPM RPM Surface temperature
(° C) Allowable temperature error range
(° C) Remarks 8 -13 ± 0.5 10 -12 ± 0.5 summer 12 -11 ± 0.5 14 -10 ± 0.5 18 -9 ± 0.5 winter 20 -8 ± 0.5 Dimensions of ice drum Diameter 120 ± 5mm, Length 200 ± 5mm, Thickness 0.7 ± 0.15mm

As shown in Table 1, in order to realize the temperature quality of the powder ice by the temperature control of the ice-making drum, a speed setting knob 107 of the ice-making drum 10 was installed in the powder ice ice-maker. When the control unit microcomputer 101 refers to the speed setting knob 107 and there is a speed adjustment request signal s107, the microcomputer 101 responds to this signal to control the drive driver 21d as the motor control signal c21. Further, the drive driver 21d controls the deceleration motor 21 to drive within the range of 8-20 times / minute of the rotation speed of the ice-making drum if the motor control signal c21 is present. The motor control signal c21 is a 2-8 bit data control signal, and an example of the speed control of the ice-making drum 10 is feedback control.

In order to perform feedback control of the rotation speed of the ice-making drum 10, the speed adjustment request signal s107 is a pulse signal which is required to increase or decrease the speed. On the ice-making drum, a magnet 17 was attached so that the microcomputer detects the rotation of the ice-making drum. The hall sensor 16 which reacts with the magnet 17 is connected to the microcomputer 101 so that the microcomputer 101 detects the magnet 17 every time the ice-making drum 10 rotates, Count. The microcomputer calculates the minute rotational speed of the ice-making drum based on the detection signal, and controls the rotational speed of the ice-making drum by raising or lowering the driving speed of the deceleration motor in the stepwise manner within the set rotational speed range.

Generally, powder ice is used within 1-2 hours after ice making. However, even during this period of use, the ice that has been made into ice is melted very quickly compared to the lump ice because it has a large surface area and many air layers between the ice. In order to protect such powdery ice, a freezing chamber 108 is provided in an ice maker and powdery ice is stored in the freezing chamber, so that the use time of the powdery ice can be prolonged and the temperature quality of the powdery ice can be maintained.

For this purpose, a common drawer type cold hearth chamber or a door opening type freezer chamber 18, in which the heat flow is blocked by using a heat insulating material in the powder ice ice maker and the cooling coil is piped, was installed. The opening and closing operations of the freezing chamber 10 are applied to the freezing chamber configuration of the existing refrigerator.

The container detecting sensor 38 is installed so that the ice-making receptacle 30 is in contact with the state change, and is connected to the microcomputer so that the microcomputer 101 can read the state signal s38. The water level sensor 31 is provided so that the microcomputer 101 can detect the high level and the low level in the container in the upper probe and the lower probe and the microcomputer 101 detects that the water level in the ice- And controls the ice-making water pump 40 to be driven until the ice-making water reaches the high water level. If the water level sensor is also used as the container detecting sensor 38, the control unit 101 should be programmed so that the icemaker 30 is regarded as being removed when the water level can not be detected even by the low-level probe do.

In the microcomputer 101 of the refrigerator control unit 100, a main word I for controlling the refrigerator is programmed. The cleaning control for controlling the cleaning has been added to the main word I of the control unit 100 so that the cleaning control can be executed.

In this case, the ice layer is frozen to a thickness of about 0.7 mm on the surface of the ice-making drum, and the ice layer is cut at the cutter 15 and collected in the ice container 14. Such an ice-maker needs to be cleaned by cleaning milk, juice, and other beverages from the ice-making drum by freezing and cutting it with a cutter to provide food for the water source. .
