Next, the operation of the water storage type ice making device according to the embodiment will be described. First, as shown in FIG. 1, the carrier 61 is pulled out from the support box 10, and a water tank 34 in which a required amount of water is supplied (full state) at another place is installed in the carrier 61.
Then, the carrier 61 is loaded into the box 10.
The rollers 72 of the carrier 61 move along the guide rails 71 and are mounted on the detection plate 73. In addition, the carrier 6
The positioning roller 77 is fitted into the front cutout portion 76a of the rail member 76 in No. 1, and the transport body 61 is stored at a fixed position. At this time, since the water storage tank 34 is full (the amount of water in the tank is larger than a predetermined value), the detection plate 73 tilts downward against the elasticity of the tension spring 75, and the weight switch Turn on the SW.
When the water storage tank 34 is stored in the support box 10, the second hose 64 is attached to the male joint 68 of the third hose 65 attached to the opening 35 of the tank 34 via the female joint 67. . Thereby, the water supply pump P
The suction port of M and the water storage tank 34 have three hoses 63,
It is connected by a water absorption hose 62 composed of 64 and 65.

In this state, when the operation switch (not shown) of the ice making machine 12 is turned on, the weight switch SW is in the on state, so that power is supplied to the ice making machine 12 side and the ice making / removing operation of the ice making machine 12 is performed. Ice driving begins. When the water supply pump PM is energized by the ice making / de-icing operation of the ice maker 12, the water in the water storage tank 34 is sucked into the pump PM via the water absorbing hose 62 and passes through the water supplying hose 52 and the supply pipe 50.

As a result, the weight switch SW is turned on as described above, and the ice machine 12 can be operated. In addition, the water storage tank 34 housed in the support box 10 has a second hose 64 of the water absorption hose 62.
The return hose 56 is communicated with the opening hose 35. When the water storage tank 34 is taken out from the support box 10, the third hose 65, which is always immersed in water and to which water stain or the like is attached, can be removed from the tank 34 and easily washed.

When the water storage tank 34 after water supply is stored in the support box 10, the operator often does not carry the carrier 61 into the correct position. For example, as shown in FIG. 6, the carrier 61 is carried over to a position where the rear end of the carrier 61 contacts the holding member 74 beyond the normal position, or as shown in FIG. Carrying in may be completed at a position before reaching. In this case, in the state shown in FIG.
Since the front end edge of the front cutout portion 76a of the rail member 76 of No. 1 is located on the front side that does not exceed the perpendicular line L passing through the center of the positioning roller 77 (see FIG. 7), the roller 77 can be operated when the operator releases his hand. The carrier 61 moves to the front side by its own weight while rotating in the direction, and the positioning roller 77 is attached to the front notch 76a.
