[0005] Since the ice making chamber 12 is cooled below freezing by the operation of the refrigeration system, a part of the ice making water injected and supplied into the chamber starts to freeze in layers on the inner wall surface of the ice making chamber 12. In addition, the non-freezing water is formed in the return hole 2
It falls from 3,23 and is collected in the ice making water tank 14.
This ice making operation proceeds, and complete ice cube 28
Is generated (see FIG. 6A), this is detected by an appropriate detecting means, and an ice making completion signal is output to stop the ice making operation. Next, a deicing operation is started, and a hot gas is supplied to the evaporator 13 by switching the valve body to heat the entire ice making chamber, thereby melting the ice formed between the inner wall surface of the ice making small chamber 12 and the ice cube 28. At a required timing, the water tray 16 tilts to open the lower opening of the ice making chamber 12 (see FIG. 6B), and the inner wall of the ice making chamber 12 and the ice cube 28 are continuously supplied by hot gas. Is gradually melted. As a result, the ice cubes 28 fall from the ice making chamber 12 under their own weight, slide down the water tray 16 diagonally downward, and are stored in an ice storage (not shown).

In the water tray structure of the automatic ice maker, ice cubes 28 are discharged from the ice maker 10 in a short time during the deicing operation. A slight gap is provided, and the ice layer 28 having a required thickness is provided in this gap.
A configuration is adopted in which each ice cube 28 is connected by forming a. In other words, the ice making compartment 1
When the frozen surface of the ice cubes 2 and the ice cubes 28 melts, the weight of all the ice cubes 28 connected to each other acts in a direction in which the ice cubes are separated from the ice making chamber 10, thereby promoting deicing. .
By the way, in a configuration in which a gap is provided between the lower end of the ice making chamber 10 and the surface of the water tray 16 to form the ice layer 28a, the ice layer 28a freezes firmly on the surface of the water tray when the ice making is completed. I have. Moreover, since the water tray 16 itself is made of a highly rigid material, the water
6 causes the frozen surface between the ice layer 28a and the water tray 16 to peel off at a time, and the water tray 16 and its tilting mechanism are separated.
(Actuator, etc.) is overloaded and ice cube 2
8 also had a problem that it could not be taken out in good condition.

[0007] Therefore, as shown in FIG. 4, a peeling resin formed of a flexible material having a property that ice blocks hardly adhere to the surface of the flat plate portion 19 forming the water tray 16. The plate 30 is provided to reduce the peeling force between the ice layer 28a and the water tray 16 during the deicing operation. The resin plate 30 is fixed to the surface of the water dish only in the vicinity of the edge, and the other portions are in contact with the surface of the water dish. As a result, the ice layer 28a and the resin plate 30 do not freeze firmly, and when the water tray 16 is tilted, the resin plate 30 bends and gradually separates from the ice layer 28a. It is possible to prevent an excessive load from being applied to the tilting mechanism or chipping of the ice cube 28.

Since the resin plate 30 is configured to be able to bend with respect to the water tray 16, the resin plate 30 is jetted and supplied from the fountain hole 21 between the resin plate 30 and the water tray 16. Ice and unfreezed water may enter and freeze. When the temperature of the tap water is high as in summer, the temperature of the ice making water supplied to the ice making chamber 12 is relatively high, so that the temperature between the resin plate 30 and the water tray 16 is early in the next ice making operation. The ice that has been frozen is melted, but the ice remains without being melted when the temperature of the ice making water drops, such as in winter. When the ice making operation and the deicing operation are repeated in this state, the ice gradually grows, and the resin plate 30 is lifted off the surface of the water dish.

That is, when the water tray 16 is brought to the ice making position, as shown in FIG. 6A, the gap between the partition plate 11 provided in the ice making chamber 10 and the resin plate 30 becomes narrower. When the resin plate 30 contacts the partition plate 11, a thin portion of the ice layer 28a or a portion where the ice layer 28a is not formed at all is generated. In this case, the thin ice layer 28a is melted at an early stage of the deicing operation, and the ice layer 2a is melted.
A group of ice cubes connected by the ice layer 28a are formed separately at a portion where there is no 8a (see FIG. 6B). Therefore, the divided ice cubes are separately discharged with a required time difference as the deicing operation proceeds according to the weight (see FIG. 6C), and are generated in the ice making chamber 10. It takes time to release all the ice cubes 28
There was a problem that Nissan's ice making capacity decreased. In the ice maker, the completion of the deicing operation is controlled by detecting a rise in the temperature of the ice making chamber 10 caused by the discharge of the ice cubes 28 from the ice making chamber 10. If the ice cubes are discharged unevenly, the degree of temperature rise differs depending on the release state, and there is a disadvantage that the detection of the completion of deicing becomes uncertain.

[0010] Furthermore, if the ice removal operation becomes unnecessarily long due to the uneven release of ice cubes, the ice cubes whose release is delayed are excessively thawed and become deformed ice or become thin and uneven in size. Difficulties are pointed out. When the ice frozen between the resin plate 30 and the water tray 16 grows large by repeating the ice making operation and the deicing operation, the resin plate 30 is moved to the ice making chamber 1.
There is also a problem that the lower end of the second member 2 is strongly hit and may be damaged.

Next, the operation of the water tray structure of the automatic ice maker according to the embodiment will be described below. When the ice making operation of the automatic ice making machine is started, the ice making water in the ice making water tank 14 is pumped to each water supply pipe 18, and as shown in FIG. The ice is supplied to the ice making chamber 12 through the hole 38. Since the ice making chamber 12 is cooled by the refrigerant supplied from the refrigeration system to the evaporator 13, the ice making water comes into contact with the inner wall of the ice making chamber 12 and is gradually cooled. It returns to the ice making water tank 14 through the return hole 23.

As the ice making operation proceeds, the ice making compartment 12
A part of the ice making water starts to freeze on the inner wall surface of the inside, and finally solid ice cubes 28 are generated. At this time, the resin plate 3
In the area where the ice making chamber 10 is closed from below in FIG. 2, only the leg 36 of the resin plate 32 is in contact with the surface of the water tray 16. Hardly penetrates between the two 32 and 16 and stays. Further, since the thermal conductivity of the resin plate 32 is small, it is difficult for the low temperature from the ice making chamber 10 to be transmitted to the lower end of the leg portion 36, and furthermore, the uniced water that did not freeze in the ice making chamber 12 during the ice making operation. Is circulated in the groove 34 and heat is exchanged by contacting the inner wall surface (the leg 36) for a long time (the low temperature of the leg 36 is taken away by the non-freezing water). The freezing temperature can be suppressed.

It is assumed that the leg 36 of the resin plate 32 and the water plate 1
Even if the ice making water penetrates between the water and the water, the contact area between the leg 36 and the water tray 16 is small, so that the ice is melted by the ice making water at the beginning of the ice making operation. That is, a uniform gap is secured between the lower end of the ice making chamber 12 and the surface of the resin plate 32, and an ice layer 28a is formed in the gap, and all the ice cubes 28 generated in the ice making chamber 10 Interconnected. In addition, the resin plate 32 has a property of easily separating ice blocks.
(The property that ice blocks do not easily adhere).
8a can be prevented from being firmly frozen on the surface of the resin plate 32.

When the ice cubes 28 are completely formed as described above, the temperature of the ice making chamber 10 drops. This is detected by an appropriate detecting means, and the ice making operation is stopped to complete the ice making. When the ice making is completed, hot gas is supplied to the evaporator 13 by switching of the refrigeration system valve, and the ice making chamber 1 is turned on.
Heat 0. The tilting mechanism is activated at an appropriate timing, and the water tray 16 starts tilting clockwise around the support shaft 17. At this time, the resin plate 32 bends with the tilting of the water tray 16 and is gradually peeled off from the lower end side in the tilting direction with respect to the ice layer 28a. As a result, no excessive load is applied to the tilting mechanism, and the ice cube 28 does not break.

When the hot gas is circulated and supplied to the evaporator 13, the frozen surface of each ice making chamber 12 and the ice cube 28 is melted. At this time, the ice cubes 28 are connected to each other by an ice layer 28a formed at a lower end thereof with a constant thickness, and all the ice cubes 28 are separated from the ice making chamber 12 at a time, so that the ice cubes can be quickly removed. It can be dropped and discharged from the ice making chamber 12. Then, the detecting means detects a rise in temperature due to the release of the ice cubes 28 from the ice making chamber 10, and turns the water tray 16 counterclockwise to close the ice making chamber 12 from below.

Thus, in the water dish structure according to the embodiment,
Since ice for pushing the resin plate 32 upward is not formed on the lower surface of the resin plate 32 for reducing the peeling force between the ice layer 28a and the water tray 16 during the deicing operation, the lower end of the ice making chamber 12 and the resin A uniform gap with the surface of the plate 32 can be secured. Therefore, all the ice cubes 28 formed in the ice making chamber 10 are connected to each other by the ice layer 28a formed in the gap, and all the ice cubes 28 fall and discharge at one time during the deicing operation, thereby shortening the deicing time. And the ability to make Nissan ice will be improved. In addition, ice cubes 28 having a uniform shape and size can be obtained. Furthermore, since the non-freezing water comes into contact with the leg portions 36 defining the groove 34 and deprives the low temperature, the ice that pushes the resin plate 32 is generated by suppressing the freezing temperature of the leg portions 36. Can be reliably prevented.

FIG. 3 shows a water tray structure of an automatic ice maker according to another embodiment of the present invention. The water tray 16 is formed on the water tray 16 based on the configuration of the above-described embodiment. The separation distance between the fountain hole 21 and the return hole 23 is set to be large. That is, for the fountain hole 21 formed at a position substantially corresponding to the center of each ice making chamber 12, the return hole 23 is formed at a position adjacent to the leg portion 36 defining the groove 34 of the resin plate 32. I have. As a result, the fountain hole 2
The ice making water injected from 1 and the non-freezing water flowing into the groove 34 through the through hole 38 of the resin plate 32 interfere with each other to prevent the flow rate of the non-freezing water from decreasing. I have.
Therefore, the non-iced water quickly flows through the inside of the groove 34 and returns to the ice making water tank 14 through the return hole 23, thereby suppressing the uniced water from entering between the leg portion 36 and the water tray 16. However, the formation of ice that pushes the resin plate 32 upward can be further prevented. Also in this alternative embodiment, it is possible to shorten the deicing time, improve the Nissan ice making capacity, and manufacture ice cubes 28 having a uniform shape and size. As shown in FIG. 3, a position where the return hole 23 is formed is preferably a position closer to the leg 36 than a position immediately below the through hole 38 in the resin plate 32. That is, since the non-icing water flowing into the groove 34 from the through hole 38 flows along the inner wall surface of the groove, the water can be quickly returned to the ice making water tank 14 through the return hole 23 near the leg 36. .

As described above, according to the water tray structure of the automatic ice maker according to the present invention, a groove is formed on the lower surface of the plate member, and only the leg that defines the groove contacts the surface of the water tray. With this configuration, ice that pushes the plate material upward is hardly formed on the lower surface of the plate material. In other words, a required gap can be reliably defined between the lower end of the ice making chamber and the surface of the plate material, and all ice cubes can be connected by the ice layer created in the gap. Thereby, all the ice cubes can be discharged at once, and the ice removing operation can be performed in a short time to improve the Nissan ice making capacity. Further, there is an advantage that the completion of deicing can be accurately detected to prevent generation of deformed ice, and that high-quality ice cubes with uniform dimensions can be efficiently manufactured. Furthermore, by increasing the separation distance between the fountain hole and the return hole, it is possible to prevent uniced water flowing into the groove through the plate material through hole from interfering with ice making water injected through the fountain hole. To return to the ice making water tank quickly through the return hole, which further reduces the generation of ice that pushes up the plate material by smoothly flowing uniced water without stagnation in the groove. obtain.
