  The ice making mechanism 20 will be described with reference to FIGS. 8 to 11. The ice making chamber 21 formed with many ice making small chambers 21 </ b> A (see FIG. 11) opened downward, the water dish 22, and the water dish 22 from below. The ice making water tank 23 is fixed, and the water tray 22 and the ice making water tank 23 are integrally tilted. The water tray 22 is formed in a substantially rectangular shape, and support arms 27 attached to the front and rear portions of the left end of the front face are spaced apart from each other in the front-rear direction of a mounting member 26 installed horizontally on the housing 11. The water tray support bracket 28 is pivotally supported via a pivot shaft 29, and the vicinity of the right end is supported by a water tray opening / closing mechanism 24. Accordingly, the water tray 22 swings the pivot shaft 29 by rotating the water tray opening / closing mechanism 24 forward and backward to horizontally close the ice making chamber 21 from below (FIG. 8). The posture is shifted to a tilted open posture (not shown) that tilts about 30 degrees from the ice making chamber 21 as the center and opens the ice making chamber 21. On the upper surface of the water tray 22, an opening 39 for the injection hole 30 for injecting ice making water to each ice making chamber 21 </ b> A of the ice making chamber 21 is provided, and the ice making water is dropped to the ice making water tank 23. A water hole 31 is established.

  The ice making water tank 23 is formed in a bucket shape having an opening wall portion 35 surrounding the outer peripheral wall portion 32 of the water dish 22 and opening upward, and the water dish 22 is disposed below the water dish 22 using a fixing means 36. It is being fixed so that 22 may be accommodated inside. The ice making water tank 23 stores ice making water supplied from a water supply unit 25 disposed on the mounting member 26. On the left side of the front wall of the ice making water tank 23, a water feed pump 33 that pumps ice making water to the injection hole 30 provided in the water tray 22 is disposed at the deepest portion of the ice making water tank 23. Further, at the right end of the bottom wall of the ice making water tank 23, that is, the portion adjacent to the inclined lower end side (right end) of the water tray 22, as shown in FIGS. A long and narrow drainage port 37 is established. Accordingly, when the ice tray 22 is tilted by opening the water tray 22, the ice-making water stored in the ice-making water tank 23 moves toward the drainage port 37 and is discharged from the drainage port 37 to the outside of the tank. It is comprised so that.

  In the ice making machine 10 configured as described above, the ice making water stored in the ice making water tank 23 is driven by driving the water feed pump 33 while the water tray 22 is held in the closed posture during the ice making operation. The water is sprayed from the spray holes 30 of the water tray 22 to the ice making chambers 21 </ b> A of the ice making chamber 21. Then, by cooling the ice making chamber 21 with the refrigeration mechanism, the ice making water gradually freezes in the ice making small chamber 21A to form ice blocks. Here, the ice making water that has not been frozen in the ice making chamber 21 </ b> A falls on the upper surface of the water tray 22, and then falls into the ice making water tank 23 through the water passage holes 31 and is collected. When the generation of ice blocks is completed in each ice making chamber 21A, the operation moves to the deicing operation to displace the water tray 22 and the ice making water tank 23 to the open posture, and the ice blocks generated in each ice making chamber 21A are moved to the water tray. The ice-making water in the ice-making water tank 23 is discharged from the drain port 37 while being dropped and discharged onto the surface 22. A drainage basin 38 is formed on the lower surface of the ice making water tank 23, and when the ice making water tank 23 tilts together with the water tray 22, the drain pan 19 in which the open end of the drainage basin 38 is located below (FIG. 7). 8), the discharged ice-making water is collected by the drain pan 19 through the drainage basin 38 and then discharged outside the apparatus. Such an ice making machine is disclosed in Patent Document 1, for example.

A hole 46 is provided. The upper wall 43 of the water tray 42 is provided with openings 47 for the respective injection holes 46 and water holes 48 through which ice-making water flows into and out of the ice-making water tank 50.

  As shown in FIGS. 1 to 3, the ice making water tank 50 has an opening wall 51 that surrounds the outer peripheral wall 44 of the water tray 42 and is formed in a bucket shape that opens upward. Then, the water tray 42 is accommodated in an opening region surrounded by the opening wall portion 51, and is fixed to the water tray 42 from below by using fixing means 52. There is an appropriate gap between the right wall 44A located at the edge (right end) of the inclined lower end of the outer peripheral wall 44 in the open water dish 42 and the right vertical wall 51A in the opening wall 51 of the ice making water tank 50. A gap S is defined, and the ice making water accumulated on the upper surface of the water tray 42 can flow down from the right end of the upper wall 43 and be collected in the ice making water tank 50.

  At the right end of the bottom wall of the ice making water tank 50, an elongated drainage port 53 extending in the required length in the front-rear direction is provided at a portion along the right wall 44A of the water tray 42. The drain port 53 comes to the lowest position of the ice-making water tank 50 when the water tray 42 is displaced to the open posture and the ice-making water tank 50 is tilted to the lower right, and enters the ice-making water tank 50. The stored ice making water moves to the drain port 53 side and is discharged from the drain port 53 to the outside of the tank. A drainage basin 54 is formed on the lower surface of the ice making water tank 23.

  And in the ice making machine 40 of an Example, as shown in FIGS. 1-3, the water-receiving wall part 60 which covers the upper direction of the said drain outlet 53 is used for the outer peripheral wall part 44 of the water tray 42, and opening of the ice-making water tank 50. It is provided over the wall 51. The water receiving wall portion 60 is provided integrally with the opening wall portion 51 of the ice making water tank 50 and extends from the right vertical wall 51A of the opening wall portion 51 toward the right wall 44A of the outer peripheral wall portion 44 of the water tray 42. And is in contact with the right wall 44A. The water receiving wall portion 60 is formed to have a front / rear width W wider than the front / rear width H of the drain port 53. Therefore, as shown in FIG. 3, the drain port 53 is completely covered by the water receiving wall portion 60 as viewed from above.

  And the water receiving guide extended in the front-back direction by the said water receiving wall part 60, the right wall 44A in the outer peripheral wall part 44 of the water tray 42, and the right vertical wall 51A in the opening wall part 51 of the ice making water tank 50. A path 63 is formed. This water receiving guide path 63 is in the front-rear direction along the right wall 44A of the water tray 42 (the direction orthogonal to the facing direction of the right wall 44A of the outer peripheral wall 44 and the right vertical wall 51A of the opening wall 51). , Openings 63 </ b> A and 63 </ b> A communicating with the ice making water tank 50 at positions away from the drainage port 53 are provided.

  Further, as shown in FIGS. 2 and 3, a front projecting piece portion 64 extending downward is formed at the front end portion 61 facing the front opening 63 </ b> A in the water receiving wall portion 60. The front projecting piece 64 is for preventing the ice making water that has flowed down to the upper surface of the water receiving wall portion 60 and moved to the front end portion 61 from flowing into the lower surface side of the water receiving wall portion 60 from the front end portion 61. It is. Further, as shown in FIGS. 2 and 3, a rear projecting piece 65 extending downward is also formed in the rear end portion 62 facing the rear opening 63 </ b> A in the water receiving wall portion 60. The rear protrusion 64 prevents the ice-making water that has flowed down in the vicinity of the rear end 62 on the upper surface of the water receiving wall 60 from flowing from the rear end 62 to the lower surface of the water receiving wall 60. Is. Therefore, the ice making water that has flowed down from the water tray 42 to the water receiving wall portion 60 by the front projecting piece portion 64 and the rear projecting piece portion 65 wraps around the lower surface of the water receiving wall portion 60 and falls into the drain port 53. Can be prevented.

  In the ice making machine 40 according to the embodiment, during ice making operation, most of the ice making water that has fallen onto the upper surface of the water tray 42 without being frozen in the ice making chamber 21 </ b> A enters the ice making water tank 50 through the water passage 48. Fall out. Further, the ice making water that has moved rightward on the upper surface of the water tray 42 without falling from the water flow hole 48 flows down from the right wall 44A of the water tray 42. Of these, the ice-making water that has flowed down from the vicinity of the front end and the vicinity of the rear end of the right wall 44A of the water tray 42 falls into the ice-making water tank 50 as it is and is collected in the ice-making water tank 50 as shown in FIG. The

  On the other hand, the ice making water that has flowed down from above the drain outlet 53 at the right end of the water tray 42 flows down to the upper surface of the water receiving wall portion 60 as shown in FIGS. Then, the ice making water that has flowed down to the upper surface of the water receiving wall portion 60 moves forward in the water receiving guide path 63 inclined downward to the front, and from the front end portion 61 of the water receiving wall portion 60, the drain port 53. It falls into the ice making water tank 50 at a position deviated from the position and collected. Further, the ice making water received by the water receiving wall portion 60 is received by the front protruding piece portion 64 provided at the front end portion 61 of the water receiving wall portion 60 and the rear protruding piece portion 65 provided at the rear end portion 62. The ice making water does not flow into the drain port 53 without going around to the lower surface of the wall portion 60.

  The water receiving wall portion 60 is provided integrally with the opening wall portion 51 of the ice making water tank 50 and is in contact with the outer peripheral wall portion 44 of the water tray 42. When the water tank 50 is displaced and a gap is formed between the water receiving wall portion 60 and the outer peripheral wall portion 44, the ice-making water falls along the right wall 44A of the outer peripheral wall portion 44. Here, as shown in FIGS. 3 and 4, the right wall 44A of the outer peripheral wall portion 44 is located slightly shifted from the drain port 53, so that the ice-making water dropped along the right wall 44A. Does not fall directly above the drain port 53, so that the flow of ice-making water into the drain port 53 can be minimized.

Therefore, the ice making machine 40 of the embodiment has the following operational effects.
(1) The ice making flow that has flowed down from the water tray 42 onto the water receiving wall portion 60 by providing the water receiving wall portion 60 larger in size than the drainage port 53 above the drainage port 53 provided in the ice making water tank 50. Since the water is dropped to a position in front of the drain port 53, the ice making water can be prevented from flowing into the drain port 53. Therefore, the ice making water in the ice making water tank 50 is not reduced below the specified amount, and the production of ice blocks in the ice making chamber 21 is not hindered.
(2) Since the water receiving wall portion 60 is inclined downward toward the front, the ice making water does not stop on the upper surface of the water receiving wall portion 60, and the ice making water smoothly falls into the ice making water tank 50. Can be.
(3) Since the front projecting piece 64 and the rear projecting piece 65 extending downward are provided on the front end 61 and the rear end 62 of the water receiving wall 60, the front end 61 and the rear end 62 are separated from each other. It is possible to prevent the ice making water from flowing into the back side of the water receiving wall portion 60, and to prevent the ice making water from flowing into the back side of the water receiving wall portion 60 and falling to the drain port 53.
(4) The water receiving wall portion 60 is integrally formed with the ice making water tank 50, and the front edge 60A of the water receiving wall portion 60 abuts against the right wall 44A of the outer peripheral wall portion 44 of the water tray 42, so The ice-making water tank 50 mounted on the tray 42 is appropriately positioned, and rattling of the ice-making water tank 50 can be prevented. The gap S is optimally held by positioning the ice-making water tank 50 with respect to the water tray 42, and the gap S is reduced so that the ice-making water on the water tray 42 becomes the opening wall portion of the ice-making water tank 50. 51 can be prevented from spilling out of the ice making water tank 50 beyond the right vertical wall 51A.
(5) Since the water receiving wall portion 60 is in contact with the right wall 44A of the water tray 42 with a gap S defined between the right end of the water tray 42 and the opening wall portion 51 of the ice making water tank 50. The water tray 42 and the ice making water tank 50 are positioned and have improved strength and are not easily deformed. Therefore, for example, at the time of switching from the ice making operation to the deicing operation after the generation of the ice block is completed, the water tray 42 having the surface of the upper wall 43 fixed to the ice block is separated from the ice block and forcibly displaced to the open posture. In making it possible, deformation of the water tray 42 and the ice making water tank 50 can be prevented. Even when an ice block is sandwiched between the water tray 42 and the ice making chamber 21 that are displaced from the open posture to the closed posture when switching from the deicing operation to the ice making operation, the water tray 42 and the ice making water tank 50 are also inserted. Can prevent torsional deformation.

(Example of change)
(1) FIG. 5 is a side view showing a water receiving wall portion 70 according to a modified example. The water receiving wall portion 70 of this modified example is a front-rear direction along the right wall (inclined lower end side) 44A of the water tray 42 (the opposing direction of the right wall 44A of the outer peripheral wall portion 44 and the right vertical wall 51A of the opening wall portion 51). In the direction orthogonal to the front end portion 63A, the front end portion 71 is gently inclined downward from the front end portion 71 facing the front opening 63A toward the rear end portion 72 facing the rear opening 63A. Therefore, the water receiving wall portion 70, the right wall 44A of the outer peripheral wall portion 44 of the water tray 42, and the right vertical wall 51A of the opening wall portion 51 of the ice making water tank 50 extend in the front-rear direction and open in the front-rear direction. In addition, a water receiving guide path 63 that is inclined downward toward the rear is defined. As a result, the ice making water that has flowed down from above the drainage port 53 at the right end of the water tray 42 is moved back in the water receiving guide path 63 after being received by the upper surface of the water receiving wall portion 70, thereby opening the rear opening. The ice making water is dropped and collected from 63A into the ice making water tank 50, and the ice making water is prevented from flowing into the drain port 53. Further, a front projecting piece portion 73 and a rear projecting piece portion 74 extending downward from the end portions 71 and 72 are formed on the front end portion 71 and the rear end portion 72 of the water receiving wall portion 70, respectively. The ice making water is prevented from entering the back of the wall 70. Therefore, the modified example can obtain the same effect as the above-described embodiment.

(2) FIG. 6 is a side view showing a water receiving wall portion 80 according to another modification. The water receiving wall portion 80 of this other modified example is orthogonal to the front-rear direction along the right wall 44A of the water tray 42 (the opposing direction of the right wall 44A of the outer peripheral wall portion 44 and the right vertical wall 51A of the opening wall portion 51). The intermediate portion 81 in the front-rear direction is the highest, and gradually inclines downward from the intermediate portion 81 toward the front end portion 82 and the rear end portion 83. Accordingly, the water receiving wall portion 80, the right wall 44A of the outer peripheral wall portion 44 of the water tray 42, and the right vertical wall 51A of the opening wall portion 51 of the ice making water tank 50 extend in the front-rear direction and open in the front-rear direction. In addition, a water receiving guide path 63 that is inclined downward and forward is defined. As a result, the ice-making water that has flowed down from above the drainage port 53 at the right end of the water tray 42 is received by the upper surface of the water receiving wall portion 80 and then moves forward or rearward in the water receiving guide path 63 to the front side. The ice making water is prevented from flowing into the drain port 53 by being dropped and collected into the ice making water tank 50 from both the opening 63A and the rear opening 63A. Further, a front projecting piece portion 84 and a rear projecting piece portion 85 extending downward from the end portions 82 and 83 are formed at the front end portion 82 and the rear end portion 83 of the water receiving wall portion 80, respectively. Ice-making water is prevented from entering the back of the wall 80. In particular, in the water receiving wall portion 80 according to another modified example, ice making water can be dispersed and dropped from the two front and rear openings 63A and 63A to the ice making water tank 50, so that the amount of ice making water dropped for each opening 63A and 63A can be reduced. It can reduce, and it can suppress that ice-making water falls while energizing by the increase in fall amount, and flows into the drain outlet 53 side.

(3) The water receiving wall portions 60, 70, 80 are formed integrally with the right wall 44 A of the outer peripheral wall portion 44 of the water tray 42, and are formed on the right vertical wall 51 A of the opening wall portion 51 of the ice making water tank 50. You may contact | abut. Even such a water receiving wall 80 can be suitably prevented from flowing into the drainage port 53 by making it larger than the drainage port 53. Further, the ice-making water tank 50 can be suitably positioned with respect to the water tray 42.
(4) The water receiving wall portions 60, 70, and 80 are formed separately from the water tray 42 and the ice making water tank 50, and the outer peripheral wall portion 44 of the water tray 42 or the opening wall portion of the ice making water tank 50. It is good also as a form attached to 51. In this case, the water receiving wall portions 60, 70, 80 can be formed from a material different from the outer peripheral wall portion 44 of the water tray 42 and the ice making water tank 50. For example, by forming the water receiving wall portion 80 from a material having elasticity, the water receiving wall portions 60, 70, 80 and the water tray 42, the water receiving wall portions 60, 70, 80, the ice making water tank 50, It is possible to improve sealing performance by abutting elastically.
(5) The water receiving wall portions 60, 70, 80 are formed integrally with the water tray 42 or the ice making water tank 50, and the ice making water tank 50 on the side with which the water receiving wall portions 60, 70, 80 abut or By attaching an elastic member having elasticity to the water tray 42, the water receiving wall portions 60, 70, 80 may be brought into contact with the elastic member to improve the sealing performance.
(6) Only one of the front projecting piece 64 and the rear projecting piece 65 may be provided. For example, in the embodiment, the water receiving wall portion 60 is inclined downward to the front, and it is difficult for the ice-making water to circulate from the front end portion 61 to the lower surface side of the water receiving wall portion 60. Even if the projecting piece 65 is provided, it is possible to prevent the ice making water from flowing to the lower surface side of the water receiving wall 60 to some extent. Further, in the modified example shown in FIG. 5, the water receiving wall portion 70 is inclined downward to the rear, and it is difficult for the ice making water to circulate from the rear end portion 72 to the lower surface side of the water receiving wall portion 70. Providing the front projecting piece 73 only at the front end 71 can prevent ice-making water from entering the lower surface side of the water receiving wall 70 to some extent.
