The degree of the swing can be adjusted by changing the fixing strength of the brackets 41 and 42.

As shown in FIG. 3, the diameter of the hole 31 is not changed without disassembling the components of the ice making unit 40, such as the screw 29 provided so as to penetrate the pressing head 20 sideways. It is large enough to be inserted into the part 31.
A heat insulating material 23 is provided between the ice storage bottom surface portion 21 and the ice making machine room ceiling portion 22. A guide member 24 is provided to prevent the heat insulating material from leaking from the hole 31 when foaming the heat insulating material 23 between the ice storage bottom surface portion 21 and the ice making machine room ceiling portion 22. Here, the ice storage bottom surface portion 21, the ice making machine room ceiling surface 22, and the guide member 24 constitute a partition wall portion.

On the other hand, a projecting portion 32 projecting downward is provided at the lower end of the cylindrical portion 24a so as to be flush with the ice machine room ceiling portion 22, and between the projecting portion 32 and the second flange portion 24c. A recess 24e is formed. Here, the protrusion part 32 and the hollow 24e comprise a draining part.

A cover member 25 that connects the pressing head 20 and the guide member 24 and closes the hole 31 is provided inside the ice storage 12. The cover member 25 includes a cylindrical portion 25a and a cylindrical portion 25b that is provided below the cylindrical portion 25a and has a diameter larger than the diameter of the cylindrical portion 25a. An inner flange 25a1 that extends horizontally inward is provided at the upper end of the cylindrical portion 25a. An outer flange 25b1 extending outward is provided near the center of the outer surface of the cylindrical portion 25b. At the lower end of the cylindrical portion 25b, four claw portions 33 each having an inclined surface extending obliquely upward and a horizontal surface extending inward from the upper end of the inclined surface are provided at equal intervals in the circumferential direction (FIG. 5 described later). reference).
The cylindrical portion 25 b of the cover member 25 is inserted into the cylindrical portion 24 a of the guide member 24, and the claw portion 33 is engaged with the first flange portion 24 b of the guide member 24.

An annular plate-shaped retaining ring 28 is fitted on the outer peripheral surface of the pressing head 20 on the screw 29. An O-ring 26 that is a first seal member is fitted into the outer peripheral surface of the pressing head 20 on the retaining ring 28. Thereby, the O-ring 26 seals between the outer peripheral surface of the pressing head 20 and the cylindrical portion 25 a of the cover member 25.
In the cover member 25, an O-ring 27, which is a second seal member, is fitted between the claw portion 33 and the outer flange 25 b 1 on the outer peripheral surface of the cylindrical portion 25 b of the cover member 25. Thereby, the space between the first flange portion 24b and the outer flange 25b1 and the space between the cylindrical portion 24a of the guide member 24 and the cylindrical portion 25b of the cover member 25 are sealed.

Next, a method for engaging the cover member 25 with the guide member 24 will be described.
A retaining ring 28 is inserted into the outer peripheral surface of the pressing head 20 above the screw 29, and an O-ring 26 is inserted into the outer peripheral surface of the pressing head 20 above the retaining ring 28. Next, in the cover member 25, the O-ring 27 is attached to the outer peripheral surface of the cylindrical portion 25b between the claw portion 33 and the outer flange 25b1. Thereafter, the cylindrical portion 25 b is inserted into the cylindrical portion 24 a of the guide member 24 from the inside of the ice storage 12.

  Next, a mechanism in which the cover member 25 engages with the guide member 24 will be described. FIG. 4 is a plan view when the guide member 24 is viewed from above, and FIG. 5 is a plan view when the cover member 25 is viewed from below. Of the first flange portion 24b, four claw insertion portions 35 that are notched at equal intervals in the circumferential direction are provided in a portion inside the cylindrical portion 24a. On the other hand, the positions of the four claw portions 33 provided at the lower end of the cylindrical portion 25b of the cover member 25 match the position of the claw insertion portion 35 shown in FIG. For this reason, the claw part 33 can be inserted into the claw insertion part 35, whereby the cylindrical part 25 b of the cover member 25 can be inserted into the hole 34 of the guide member 24. After the cylindrical portion 25 is inserted into the hole 34, the claw portion 33 is engaged with the first flange portion 24b by rotating the cover member 25 left or right. As a result, the cover member 25 cannot be lifted upward, and the cover member 25 is engaged with the guide member 24.

Next, the operation of the auger type ice making machine according to this embodiment will be described.
As shown in FIG. 1, when a refrigeration circuit (not shown) is operated, ice is made on the inner peripheral surface of the refrigeration casing 13, and this ice is transferred upward while scraping off an auger (not shown) provided in the refrigeration casing 13. . The scraped ice passes through a compression passage (not shown) provided inside the pressing head 20 to become stick-shaped ice. When the bar-shaped ice is pressed against the cutter 14, the ice 15 has an appropriate length and is stored in the ice storage 12. As the amount of ice 15 in the ice storage 12 increases, the mountain of ice 15 activates the ice storage detector 16 and the ice making operation is stopped.
The user can use the ice 15 stored in the ice storage 12 by opening the door 18 and scooping the ice 15 from the take-out port 17 with a scoop or the like.

However, during the ice making operation, not all of the ice making water becomes ice, and a part of the ice making water is sent into the ice storage 12 as water. Moreover, a part of the ice 15 stored in the ice storage 12 may melt and become water. Such water flows down the gap between the ice 15 and accumulates on the ice storage bottom surface portion 21.
As shown in FIG. 3, the water accumulated on the ice storage bottom surface portion 21 flows into the ice making machine chamber 11 through the hole portion 31, wets the geared motor 19, a refrigeration circuit (not shown), etc., and causes electric leakage and the like. There is a fear. However, since the space between the outer peripheral surface of the pressing head 20 and the cover member 25 is sealed by the O-ring 26, water is prevented from flowing into the ice making machine chamber 11 through this space. Further, since the space between the cover member 25 and the guide member 24 is sealed by the O-ring 27, water is prevented from flowing into the ice making machine chamber 11 through this space. Therefore, the water accumulated in the ice storage 12 is prevented from flowing into the ice making machine room 11 through the hole 31.

Further, since each component such as the pressing head 20, the cover member 25, and the guide member 24 has a dimensional tolerance, the mounting position of each component is shifted, and the sealing function by the O-rings 26 and 27 becomes insufficient, and ice storage is performed. There is a possibility that the effect of preventing water leakage from the storage 12 to the ice making machine room 11 is lowered.
Therefore, for example, as shown in FIG. 6A, a clearance 50 that is a space between the inner flange 25a1 of the cover member 25 and the retaining ring 28 is appropriately provided. Then, when the position of the pressing head 20 is relatively shifted upward due to the dimensional tolerance of each component, the clearance 50 becomes small. Conversely, when the position of the pressing head 20 is shifted downward, the clearance 50 increases. That is, by securing the clearance 50, the sealing function of the O-ring 26 can be maintained. The same applies to the O-ring 27. In this way, it is possible to cope with the vertical displacement based on the dimensional tolerance of each component.
On the other hand, the horizontal displacement can be dealt with by a configuration in which the lower part of the ice making unit 40 is fixed by brackets 41 and 42 as shown in FIG. That is, the horizontal displacement is absorbed by the pressing head 20 swaying in the horizontal direction according to the fixing strength of the brackets 41 and 42. As a result, the sealing function of the O-rings 26 and 27 can be maintained.

Furthermore, even if the water in the ice storage 12 does not flow into the ice making machine room 11, condensation occurs in the cylindrical part 24a of the cover member 25 or the guide member 24, and this condensation is transmitted to the ice making machine room ceiling part 22 to any position. , And the geared motor 19 and the refrigeration circuit may be wetted to cause electric leakage.
However, as shown in FIG. 7, since the drainage portion 32 is provided at the lower end of the cylindrical portion 24a, the condensation 30 flowing down the cylindrical portion 24a does not flow in the direction indicated by the arrow B. It flows down in the direction of arrow A and falls onto the freezing casing 13. For this reason, dew condensation is prevented from falling on the geared motor 19. As shown in FIG. 2, the dew condensation 30 that has fallen on the refrigeration casing 13 is collected and drained in a drain pan 43 provided under the ice making unit 40. This prevents the refrigeration circuit or the like directly provided on the bottom surface 11a of the ice making machine room 11 from getting wet.

As described above, the O-ring 26 prevents the water in the ice storage 12 from flowing into the ice making machine chamber 11 from between the pressing head 20 and the cover member 25, and the O-ring 27 prevents the cover member 25 and the guide member from flowing. 24, the water in the ice storage 12 is prevented from flowing into the ice making machine room 11, and therefore, water leakage from the ice storage 12 to the ice making machine room 11 can be prevented.
Further, by providing a draining portion 32 at the lower end of the guide member 24 fitted in the hole portion 31 that communicates between the ice storage 12 and the ice making machine chamber 11, even if the condensation 30 generated in the guide member 24 flows down. The dew condensation 30 is not transmitted to the ice making machine room ceiling 22 but falls onto the freezing casing 13 and is stored and drained in the drain pan 43 provided below the ice making unit 40. It can prevent the refrigeration circuit from getting wet.

  In addition, although the draining part was comprised by forming the groove-shaped hollow 24e between the protrusion part 32 and the 2nd flange part 24c, the shape of a hollow is not limited to groove shape. As shown in FIG. 8, the same effect can be obtained even when the draining portion is formed so that the shape of the recess becomes a step upward from the lower end 51 a of the protruding portion 51.
