(Effects of Example)
Next, the operation of the ice dispenser according to the embodiment will be described. In the ice dispenser 10, the opening 14a is always closed by the front door 30, and the elastically deformable packing 30a is interposed between the back surface of the front door 30 and the recess 14b of the ice storage 14 without any gaps. The heat insulation state of the ice storage 14 is suitably maintained. At this time, in each of the lock mechanisms 34A and 34B, the flange member 36 is inserted into the engagement hole 38a of the engagement member 38 to restrict the movement of the front door 30 in the opening direction. In the closed state of the front door 30, as shown in FIG. 2, the front end portions of the rotary shafts 52 and 62 are inserted into the insertion holes 56a and 66a of the corresponding couplings 56 and 66, and the pins 53 and 63 are The slits 56b and 66b are connected in a state of being fitted respectively.

  The ice dispenser 10 drives the motor M and rotationally drives the first coupling 56 via the first transmission means 41, 43, 44, so that the first rotating shaft 52 engaged with the first coupling 56 is obtained. , The ice delivery screw 50 is driven to rotate, and the ice block is conveyed toward the ice discharge port 28 and discharged. At the same time, the second coupling 66 is rotationally driven through the second transmission means 45, 47, 48, the second rotating shaft 62 engaged with the second coupling 66 is rotated, and the agitator 60 is rotationally driven. Ice blocks stored in the ice storage chamber 16 are agitated.

  For maintenance such as cleaning of the ice delivery screw 50 and the agitator 60, the front cover 12a is removed from the ice storage 14, and then the sliding member 36 of each lock mechanism 34A, 34B is slid in a direction to retract from the engagement hole 38a. Then, with the engagement state between the flange member 36 and the engagement member 38 being released, the opening 14a is opened by pulling the front door 30 to the near side with the pair of hinge members 32, 32 as the rotation center. . At this time, as the front door 30 is opened, the motor M, the two transmission means 41, 43, 44, 44, 47, 48 and the couplings 56, 66 disposed on the front door 30 are moved forward. The pins 53 are extracted along the slits 56b and 66b, and the front ends of the rotary shafts 52 and 62 are extracted from the insertion holes 56a and 66a. The engagement state is released.

  The front end portion of the first rotating shaft 52 in the ice delivery screw 50 is held by the first coupling 56 by being supported by the lower edge portion of the shaft hole 29 a formed in the front surface portion of the chute 29. It is left in the ice storage chamber 16 in substantially the same posture as when. Similarly, the front end portion of the second rotating shaft 62 in the agitator 60 is supported by the recessed portion 17 a of the support member 17, so that the ice storage chamber 16 has the substantially same posture as that held by the second coupling 66. Left behind. The ice delivery screw 50 slides forward to extract the rear end portion of the first rotary shaft 52 from the first rear bearing 55, and then slides backward while lifting upward to move the first rotary shaft from the shaft hole 29a. By extracting the front end portion of 52, the ice storage 14 can be taken out. On the other hand, since the agitator 60 is only placed in the recess 17a where the front end portion of the second rotation shaft 62 opens upward, the agitator 60 slides forward to move the rear end portion of the second rotation shaft 62 to the second rear end. After being extracted from the bearing 65, it can be taken out from the ice storage 14 by lifting upward.

  In this way, the ice dispenser 10 opens the front door 30 so that the connection state between the shaft portions 58 and 68 and the front end portions of the rotation shafts 52 and 62 is released without any special operation and does not contact the ice block. Therefore, the motor M and the transmission means 41, 43, 44, 45, 47, 48 that do not need to be cleaned can be retreated from the ice storage 14 while being held by the front door 30. Further, since the motor M and the like that are heavy can be held by the front door 30, the disconnection of the electric wire, the dropping of the device, and the like do not occur. On the other hand, the ice delivery screw 50 and the agitator 60 that need to be cleaned to come into contact with the ice block are separated from the couplings 56 and 66 and remain in the ice storage chamber 16 when the front door 30 is opened. Maintenance can be carried out in accordance with such maintenance. Since the opening 14a is provided on the front surface side of the ice storage 14, the maintenance such as cleaning can be easily performed on the ice storage chamber 16 and the devices such as the ice storage switch disposed in the ice storage chamber 16 without removing the ice making mechanism and other devices. Can be implemented. And since the opening part 14a exists in a low position, a maintenance operation | work can be made easy and work efficiency can be improved. Even if the ice dispenser 10 is installed, if the front cover 12a can be removed, the ice storage chamber 16 can be maintained, and therefore the ice dispenser itself can be moved without requiring a large work space for the work. It does not need.

  Next, the process of engaging the couplings 56 and 66 with the rotating shafts 52 and 62 will be described. The rear end portion of the first rotating shaft 52 is held by the first rear bearing 55, and the front end portion is supported by the shaft hole 29 a of the chute 29, whereby the ice delivery screw 50 is accommodated in the ice storage chamber 16. Further, the rear end portion of the second rotating shaft 62 is held by the second rear bearing 65, and the front end portion is supported by the hollow portion 17 a of the support member 17. Prior to closing the front door 30, the positions of the pins 53, 53 of the first rotating shaft 52 and the positions of the slits 56b, 56b of the first coupling 56 are matched using the marks 70, 70, and the second The positions of the pins 63 and 63 of the rotating shaft 62 and the positions of the slits 66 b and 66 b of the second coupling 66 are matched using the marks 70 and 70. That is, by aligning the positions of the pins 53, 53, 63, 63 and the slits 56b, 56b, 66b, 66b with the same scale of the mark 70, both the pins 53, 53, 63, 63 and the slits 56b, 56b, The angles of 66b and 66b can be adjusted. Since the front end portion of the first rotating shaft 52 is supported by the lower edge portion of the shaft hole 29a and has substantially the same posture as the engaged state with the first coupling 56, both the 52, When the front doors 30 are completely closed, the front end portions are inserted into the insertion holes 56a, and the pins 53 are connected to the slits 56b in a state of being inserted and engaged. Similarly, the front end portion of the second rotating shaft 62 is supported by the recessed portion 17a of the support member 17 and has substantially the same posture as the engaged state with the second coupling 66, so that the front door 30 is closed. When the two doors 62 and 66 are aligned and the front door 30 is completely closed, the front end portion is inserted into the insertion hole 66a, and the pins 63 are connected to the slit 66b in an inserted engagement state.

  In this way, the ice dispenser 10 can engage the rotating shafts 52 and 62 and the corresponding couplings 56 and 66 without any special operation by closing the front door 30. Can be reduced.
