いという欠点があった。In the above-mentioned ice making machine, the ice making water supplied from the ice making water tank to the water receiving tray through the supply pipe is placed at a position corresponding to each ice making chamber of the ice making body at the bottom of the water receiving tray. Water is supplied to each ice making chamber through the through hole. In this case, in order to form transparent and high-quality ice blocks in all the ice making chambers, it is necessary to uniformly distribute and supply the ice making water to each ice making chamber. However, since ice making water is supplied to the water receiving tray through a supply pipe provided at a predetermined position, and the ice making water is sprayed directly from the through hole to the ice making chamber, the supply pipe is initially provided in the ice making operation. Although a large amount of ice-making water is sprinkled and supplied to the ice-making chamber in the position close to, the ice-making chamber in a position apart from the supply pipe may not be sufficiently sprinkled and supplied. As a result, there is a drawback that defective ice is formed due to lack of ice making water, or white turbid ice mixed with air is generated due to insufficient flow of water, so that a transparent and good quality ice block cannot be obtained.

However, any of the methods has a drawback that the structure is complicated and the cost is high. Further, in the method (1), there is a problem that the ice thickness cannot be obtained because the ice thickness changes due to variations in the shape of the tank and the mounting position of the detection switch. The method of (1) has a problem that a certain amount of ice cubes cannot be formed due to the influence of changes in the outside temperature. In addition, the method (1) has a drawback in that the mechanism is complicated and thus is likely to fail.

As compared with the ice making water, the amount of the ice making water that returns to the ice making water tank 34 through the ice making body 28 is reduced and reduced, so that the ice making water is gradually stored in the water tray 30 and the water level rises. This is utilized to detect the completion of ice making. That is, the water tray 30
The float switch 52 is arranged in the above, and the float 52a of the switch 52 is configured to move up and down according to the change in the water level of the ice making water supplied from the ice making water tank 34 to the water tray 30. Then, when the float 52a rises to a predetermined position (when ice cubes are formed in the ice making chamber 26a), the switch 52
Is set to detect that the ice making water is stored at a predetermined water level in the water tray 30 and stop the ice making operation and switch to the deicing operation. According to this method, the structure is extremely simple, and the completion of ice making can be accurately detected without being affected by the outside air temperature and the like. Further, when ice cubes drop off from the ice making cell 26 by the deicing operation, the water receiving tray 30
The ice making water stored in the ice making chamber 26a again passes through the through hole 50a of the current plate 50 and the slit 46a of the recess 46.
Since the water level of the ice making water in the water receiving tray 30 lowers, the completion of the deicing operation is detected by lowering the float 52a at this time.

氷水が凍結して氷層が形成される。Next, the operation of the water sprinkling structure according to the embodiment will be described. The ice making water in the ice making water tank 34 is supplied to the water receiving tray 30 via the pump motor 38 and the supply pipe 40. The ice-making water supplied to the water receiving tray 30 flows over the entire upper surface of the current plate 50 placed on the inner bottom surface of the water receiving tray 30, and flows into the center of the corresponding recess 46 from each through hole 50a. In this case, since the through hole 50a is set smaller than the opening size of the recess 46 as described above,
It is possible to suppress the change in the amount of ice-making water depending on the arrangement position of the supply pipe 40 at the initial stage of the ice-making operation to a low level, and to flow a uniform amount of ice-making water into all the recesses 46. Then, as shown in FIG. 1, the ice-making water is dropped onto the bottom surface of the recess 46 and then flows in four directions along the bottom surface and is sprayed from the four slits 46a toward the four inner wall surfaces of the ice-making cell 26 at a substantially right angle. Then, each wall is flowed down uniformly. The ice making water that has flowed while being in contact with the inner wall surface of each ice making cell 26 and being cooled is returned to the ice making water tank 34 through the through hole 42 a of the chute 42 and is again provided for circulation. While the circulation of the ice making water is repeated, as shown in FIG. 5, the ice making water is frozen on the inner wall surface of each ice making chamber 26a to form an ice layer.

Is supplied to all the ice making chambers 2 in the ice making body 28.
It is possible to supply a substantially uniform amount of ice-making water to 6a. Moreover, since each slit 46a of the concave portion 46 faces each wall surface that defines the ice making chamber 26a, the ice making water flows down evenly on each wall surface, and deficient ice is formed due to lack of ice making water, or the water flow. Due to the shortage, transparent and good quality ice cubes are formed without producing cloudy ice mixed with air.

給を停止して製氷運転を完了する。As the ice making operation progresses and an ice layer grows on each wall surface of the ice making chamber 26a, as shown in FIG. 5, the opening area of the ice making chamber 26a becomes small and the amount of ice making water flowing down is reduced. Less. On the other hand, since a fixed amount of ice making water is supplied from the ice making water tank 34 to the water tray 30,
Ice-making water is gradually stored in the water receiving tray 30, and the float 52a of the float switch 52 rises as the water level rises. When the ice level of the ice making water in the water tray 30 exceeds a required level due to the formation of complete ice cubes in the ice making chamber 26a, the floats 52a actuate the float switch 52 to form ice cubes. Detect that. When the ice making completion is detected by the float switch 52, the circulation supply of the ice making water is stopped to complete the ice making operation.

る。Next, the refrigerant circulation system valve is switched to supply hot gas to the evaporation pipe 32 to heat the ice making cell 26, thereby accelerating the melting of the icing surface between the inner wall surface of each ice making chamber 26a and the ice cubes. Let When this deicing operation progresses and the icing surface between the inner wall surface of each ice making chamber 26a and the ice cubes melts, the ice cubes are separated from the ice making chamber 26a by their own weight and slide off the chute 42 to the ice storage chamber 22. Is released. Further, when ice cubes drop from the ice making cell 26, the ice making water stored in the water receiving tray 30 flows into the ice making chamber 26a through the through hole 50a of the straightening vane 50 and the slit 46a of the recess 46, so that the water receiving tray The water level of the ice making water in 30 falls. Therefore, the float 52a of the float switch 52 descends and the switch 52a
Is activated and the deicing operation is completed, and the operation shifts to the ice making operation again.

廉に抑えることができるものである。As described above, in the water sprinkling structure of the embodiment, the recesses 46 corresponding to the ice making cells 26 formed in the water tray 30 are formed.
In addition, slits 46a corresponding to the four wall surfaces that define the ice making chamber 26a are formed, and the current plate 50 is provided with through holes 50a at positions corresponding to the recesses 46, respectively.
The ice making water is uniformly sprayed and supplied to the four wall surfaces of the ice making chamber 26a. As a result, good ice cubes are formed in all the ice making chambers 26a, and it is possible to prevent formation of cloudy ice or defective ice. Further, when ice cubes are formed in the ice making chamber 26a, a change in the water level of the ice making water supplied from the ice making water tank 34 to the water tray 30 and stored therein is detected to detect the completion of ice making. Therefore, it is possible to detect the completion of ice making with high accuracy without being affected by the operating conditions such as the outside air temperature, and it is possible to always manufacture ice cubes with a constant quality. Moreover, since the structure is extremely simple, the manufacturing cost can be kept low.
