It is supported and located directly below the ice making compartment 10. During the ice-making operation, the water tray 20 is positioned horizontally to close the opening of the ice-making chamber 14, and during the ice-making operation, it is energized by an actuator (not shown) and centered around the pivot shaft 18 as shown in FIG. The opening is tilted as shown in the figure to open the opening. On the surface 20a of the water tray 20, there is an ice making compartment 1.
A fountain hole 22 and a return hole 24 corresponding to each of 4.

After being pumped through the suction pipe 34 and the discharge pipe 38 to the pressure chamber 36 by driving the pump 32, it is distributed from the pressure chamber 36 to each distribution pipe 26, and the fountain hole 2
2 and is injected and supplied to the ice making chamber 14. At this time, the ice-making chamber 14 is cooled by exchanging heat with the refrigerant circulating in the evaporator 16 during the ice-making operation, so the temperature of the ice-making water supplied into the chamber is lowered, and then The water returns to the ice-making water tank 28 from each return hole 24 and is again circulated and supplied to the ice-making chamber 14 by the pump 32. When the temperature of the ice-making water is cooled to nearly 0° C. by repeating this process, a portion of the ice-making water gradually begins to freeze from the internal top surface and inner wall surface of the ice-making chamber 14. As shown in FIG. 6, the process in which ice grows in each ice-making chamber 14 is in the order of ~ ice-making water that has not frozen (unfrozen residual water).
drops from the return hole 24 of the water tray 20 and is collected in the ice-making water tank 28.

Next, deicing operation is started, and hot gas is supplied to the evaporator 16 by switching the valve body to heat the ice making chamber 10 and melt the frozen ice between the inner wall surface of the ice making chamber 14 and the ice cubes. Then, the water tray 20 is tilted at a required timing to open the lower opening of the ice making chamber 14, and the space between the ice cube and the wall of the ice making chamber is gradually melted by the continuously supplied hot gas. The ice cubes then fall from the ice making chamber 14 under their own weight, slide diagonally downward on the water tray 20, and are stored in an ice storage (not shown).

縮させ得る決め手に欠けるのが現状である。Problems to be Solved by the Invention In the injection type automatic ice maker according to the above-mentioned mechanism, ice making water is cyclically injected into the ice making compartment 14 to gradually grow ice, so it is possible to achieve economical ice making operation. In order to achieve this, various attempts have been made to shorten the ice making time. The most common method is to increase the capacity of the refrigeration system to improve the cooling capacity of the evaporator, but this is undesirable because it inevitably increases manufacturing costs and running costs. Therefore, it is possible to improve the efficiency of cooling in the ice making chamber 14 without increasing the capacity of the refrigeration system, but at present there is no decisive factor that can effectively shorten the ice making time.

ていた。 Furthermore, in the injection type automatic ice maker, when shifting from ice making operation to ice cooling operation, the water tray 20 is forcibly tilted to open the ice making chamber 14 and ice cubes are dropped and released. This tilting of the water tray 20 is not so easy and is accompanied by various inconveniences. That is, since there is a slight gap between the lower end surface of the partition plate 12 that defines the ice-making compartment 14 and the surface 20a of the water tray 20, ice is not formed during the ice-making operation. As a result, the lower end surface of the partition plate 12 and the surface 20a of the water tray 20 are strongly frozen.
In addition, the ice cubes grown in the ice making chamber 14 are stored in the water tray 20.
It adheres almost entirely to the surface 20a. Therefore, in order to tilt and lower the water tray 20 upon completion of ice making, it is necessary to forcibly peel off the frozen portion, but for this purpose, the actuator for driving simply includes the water tray 20.
A pair of powerful torques are required to rotate the tank 28, and a large and expensive motor is required, which increases manufacturing costs. In addition, the noise generated when the water tray 20 is peeled off from the ice-making chamber 14 is large, and when the water tray 20 is peeled off, an excessive mechanical load is applied to the water tray 20, the support plate 11, the support arm 13, etc., shortening the life of the parts and causing failure. It was the cause.

めて不経済である。 In addition, as shown in FIGS. 5 and 7, the remaining part of the peeled frozen layer is attached to the surface of the tilted water tray 20. For this reason, the adhered ice 21 may block the water fountain 22, or the ice cubes that have fallen from the ice making chamber 14 may get caught in the adhered ice 21, and the ice making water may not be spouted out smoothly during the next ice making operation. Accidents have also occurred in which ice 21 is caught between the water tray 20 and the water tray 20, causing damage to the water tray 20 and the like. In order to melt the adhering ice 21 on the tilted water tray 20, water is sprinkled from the water supply pipe 40 onto the water tray 20 at the required timing, but this reduces the amount of water consumed in one ice-making operation. It means increase, which is extremely uneconomical.

The freezing of the ice-making water sprayed into the interior can be accelerated. That is, as shown in FIG. 3, the ice-making water injected into the ice-making chamber 14 is
It is cooled not only by the internal top surface and the inner wall surface of the ice making chamber 4, but also by the thermally conductive material 42 located on the surface of the water tray 20 and serving as the bottom of the ice making compartment 14. The process by which ice grows in each ice-making compartment 14 is in the following order, and ice cube production is achieved considerably faster than in conventional ice-making machines. Furthermore, during deicing operation, the ice making compartment 10 is heated by flowing hot gas into the evaporator 16, but in this case also in the present invention, the thermally conductive material 42 in contact with the ice making compartment 10 is quickly heated. , the frozen portion between the ice cubes and the water tray 20 generated by the ice making operation can be quickly melted.

広げたものである。 Furthermore, as explained from FIGS. 1 and 2,
The reason why the area where the thermally conductive material 42 is disposed on the surface of the water tray 20 extends beyond the rectangular outer frame surface of the ice making chamber 10 is as follows. That is, as described above, the lower end of the partition plate 12 in the ice-making compartment 14 is dimensioned so as to be in close contact with the thermally conductive material 42, but this may not necessarily be perfect. Therefore, partition plate 1
Ice-making water leaking from between the lower end of the ice-making chamber 10 and the thermally conductive material 42 flows into the water tray 20 at the outer frame surface of the ice-making chamber 10.
In order to prevent this from freezing, the area where the thermally conductive material 42 is disposed is extended beyond the outer frame surface of the ice making chamber 10.

のものが、各種の試験を通じて選択される。 On the outer surface of the thermally conductive material 42, a non-icing film 44 made of, for example, fluorocarbon resin represented by Teflon (registered trademark) is formed in advance. Since this anti-icing film 44 has a property that makes it difficult for ice to adhere to it, it prevents ice from forming firmly on the surface of the water tray 20 during ice-making operation, and prevents ice from forming on the surface of the water tray 20 when the water tray is tilted, as will be described later. This prevents any load from being applied to the water tray 20. It should be noted that the anti-icing film 44 made of fluorocarbon resin or the like is selected through various tests to be made of a material that is excellent in durability and moisture resistance, and also meets food hygiene standards.

水皿２０も冷却される。Effects of the Embodiment In the water tray structure of the ice making machine according to the present invention configured as described above, when ice making operation is started, the ice making water in the ice making water tank 28 is pumped through the pressure chamber 36 and the distribution pipe 26 by the pump 32. The water tray 20 is fed under pressure.
The water is sprayed from the water fountain hole 22 into the corresponding ice making chamber 14. Since the ice-making chamber 14 is cooled by the evaporator 16, the ice-making water is cooled by contacting the inner wall of the ice-making chamber 14 and the thermally conductive material 42 of the water tray 20, and then returns from the return hole 24 of the water tray 20. It flows down and returns to the ice making water tank 28. As shown in FIGS. 1 and 3, the partition plate 12 defining the ice-making compartment 14
Since the ice-making compartment 14 is in contact with the thermally conductive material 42 of the water tray 20, the water tray 20 is also cooled as the ice-making compartment 14 is cooled.

が生成されるに至る。 That is, as the ice-making water circulates between the ice-making water tank 28 and the ice-making compartment 14, the temperature of the ice-making water gradually decreases, and when the temperature reaches nearly 0°C,
As shown in FIG. 3, the inner top surface of the ice-making chamber 14,
Ice making compartment 1 located on the inner wall surface and the surface of the water tray 20
A portion of the ice-making water begins to freeze at the bottom of the heat conductive material 42. In this way, each ice making compartment 14
Freezing inside the ice gradually progresses until solid ice cubes are formed.

力は極めて弱いものである。 As shown in FIG. 2, since the thermally conductive material 42 is not formed around the fountain hole 22 and the return hole 24, there is no heat-conducting material 42 formed around both the holes 22 and 24 until the final stage when ice cubes are formed. It never freezes. Therefore, the ice-making water is smoothly injected into the ice-making chamber 14, and the formation of cloudy ice due to insufficient circulation of the ice-making water is prevented. Also, at this point, the surface 2 of the water tray 20 is
Although a freezing layer is formed on Oa, the freezing force is extremely weak because it is formed through the aforementioned anti-icing film 44.

は傾動をすることなく水平姿勢を保持している。 When the ice cubes are completely formed in this way, the temperature of the ice making chamber 10 drops, and this is detected by an appropriate detection means, and the ice making operation is stopped to complete the ice making. At the same time as ice making is completed, the hot gas valve is switched, hot gas flows into the evaporator 16, and the ice making chamber 10 is heated (start of slow ice operation). Along with this, the thermally conductive material 42 of the water tray 20 is also heated, and the water tray 2
The melting begins between the surface of the ice cube and the ice cube. Note that at the time of completion of ice making and the start of ice removal, the actuator motor is not yet energized, so the water tray 20
maintains a horizontal position without tilting.

用することが可能である。 As described above, as the water tray 20 is heated, the space between the water tray 20 and the ice cubes gradually melts, and the ice cubes begin to loosen. Also ice making room 10
The ice cubes are heated by the hot gas, and the ice between the ice cubes and the inner wall of the ice making chamber 14 begins to loosen. Then, at a predetermined timing, the actuator motor is energized to tilt the water tray 20. At this time, the water tray 20 and the ice cubes have loosened, so the water tray 20 can be lowered smoothly without any excessive load being applied to the water tray 20. Therefore, the actuator motor for rotationally biasing the water tray 20 needs to be small and inexpensive, unlike the conventional actuator motor, which requires a strong enough torque to forcibly peel off the solid ice. is possible.

Since it is in direct contact with the opening end of the water tray 20 and no ice is formed there, the peeling noise generated when tilting can be suppressed to a low level, and no excessive load is applied to the water tray 20 itself, resulting in less trouble and quiet operation. Ice making operation is achieved. Further, since no frozen pieces are formed on the surface of the water tray 20 after tilting, there is no need for the washing water that is conventionally sprayed to melt the remaining frozen pieces on the water tray.

いる。このため次の利点が得られる。Effects of the invention As explained above, according to the invention, in an automatic jet ice maker in which the lower openings of a large number of ice-making compartments are closed by a water tray in a tiltable and openable manner, the water fountain hole and the return hole on the surface of the water tray can be closed. By placing a thermally conductive material coated with a non-icing film on the surface of the area that avoids the area around the drilling site, it is configured to be able to cool and heat the water tray as well as the ice making compartment. . Therefore, the following advantages can be obtained.

It is possible to shorten ice cube generation time, increase ice making capacity, and reduce running costs.

いる。 By forming an anti-icing film on the contact surface between the ice making chamber and the water tray, the freezing force between the water tray and the ice making chamber can be reduced, and therefore the actuator that biases the water tray can be , it does not require strong torque and can be small and inexpensive. Further, when the water tray is tilted, no load is applied to the water tray, the support plate, the support arm, the ice making chamber, etc., which reduces the frequency of breakdowns and eliminates peeling noise. The anti-icing film also has a rust-preventing function for the thermally conductive material.

り、外観上変形のない良質の氷が得られる。 As the surface of the water tray is heated and the contact surface with the ice cubes melts, the water tray tilts and the ice cubes that fall and are released from the ice making compartment become smooth on each side and deformed in appearance. You can get high quality ice without any ice.
また水皿の表面に氷結部が残存しないため
に、従来の如く洗浄水を傾動した水皿に散布し
て氷結部の融解を行なう必要もなく、消費水量
の節約が図られる。 Further, since no frozen portion remains on the surface of the water tray, there is no need to spray washing water onto a tilted water tray to melt the frozen portion, as in the conventional method, and the amount of water consumed can be saved.

然に防止される。 Since no thermally conductive material is disposed around the fountain hole and the return hole, freezing does not occur around the two holes until the final stage when complete ice cubes are formed. Therefore, ice-making water is always smoothly sprayed into the ice-making chamber through the water fountain during ice-making operation, and the formation of cloudy ice due to insufficient circulation of ice-making water is prevented.
