Like the configuration shown in Japanese Patent No. 68, the ice-making surface is arranged perpendicular to the front door of the ice storage, and the ice-making part is arranged on the upper right side of the ice storage and the machine room is arranged on the upper left side. There are things to do.

Now, a configuration equivalent to the former publication is shown in FIG.
FIG. 5 and FIG. 6 and those having the same structure as the latter publication are shown in FIG. 7, FIG. 8 and FIG. Since the configuration of each part is the same in each figure, the outline of the flow-down type ice making machine will be described with reference to FIG. The ice making unit 1 has an uneven ice making surface, and a pair of ice making plates 2.2 arranged to face each other substantially vertically, a cooling pipe 3 arranged between the back surfaces of the ice making plate 2.2, and ice making water on the ice making surface. Water sprinkler 4 for sprinkling water, and ice making plate 2.2 during ice removal
The ice spray sprinkler 5 that flows ice removal water on the back surface of the water, and the unfrozen water received by the water receiving trough 6 are collected in the water storage tank 7, and the water storage tank 7
It is composed of a water circulating unit 9 which circulates and supplies water for ice making to the water sprinkler 4 for ice making through a pipe 8 by a pump P therein. In the machine room 11, a condenser unit 17 including an electric compressor 13, a condenser 14, a condenser fan 15, a capillary tube 16 and the like, which are connected in sequence by a refrigerant pipe 12 together with the cooling pipe 3 to form a refrigeration cycle, and a refrigeration cycle. Water supply having an electric equipment box 18 containing a control device for controlling the operation of the water supply system and the water supply control to the ice making unit 1, a hot gas circuit having a hot gas valve 19 additionally provided in the refrigeration cycle, and a water supply valve 21. The pipe 22 and the like are stored and arranged. The ice making unit 1 and the machine room 11 are partitioned by a heat insulating partition plate 24, and the ice making unit 1 is covered by a heat insulating cover 25 that is open only on two surfaces, a bottom surface and a rear surface.

A water storage 27 formed by a heat insulating wall
An ice outlet 28 is opened on the front side of the ice, and a door 29 for ice extraction is provided here with a door mask 30 arranged on the back thereof so as to be openable and closable, and ice i from the ice making unit 1 is stored in the ice storage unit 27A. An ice guide 32 for guiding the fall is attached. In addition, a water storage sensor 33b that detects the amount of stored water and generates detection signals related to operation of the refrigeration cycle, water supply control, and the like.

A door mask stopper 34 is attached to the upper edge.

[0005]

By the way, in the case of the structure shown in FIG. 4, looking at the accumulation state of the ice i from the ice making unit 1 in the ice storage unit 27A, as shown in the shadow diagram a, Since ice falls and accumulates with the front side, that is, the portion near the door 29 as the apex, pressure of ice from the inside of the refrigerator is applied,
There is a problem that the door 29 opens, and when the door 29 is opened, ice will spill out of the refrigerator.

In order to prevent this, measures such as provision of parts such as an ice guide 32 to drop the ice on the back side and receiving the pressure of the ice to prevent the door 29 from being pressured from the inside are taken. There is.

Considering the time of taking out the ice, the ice guide 32 has a narrow opening in the up-down direction of the ice take-out port 28, which causes a problem that the ice cannot be properly scooped when scooping the ice with a scoop or the like. At the same time, when the ice is scooped, the water storage sensor 33b is on the side wall of the product and is close to the ice outlet 28, so that there is a problem that the user is likely to damage the ice storage sensor 33b with a scoop.

Therefore, in order to prevent the ice storage sensor from being damaged,
As shown in FIG. 5, it is considered that the ice storage sensor 33C (infrared type) is located below the back surface of the ice storage 27.
As shown in FIG. 6, even when the ice storage 27 has a sufficient amount of ice storage (two-dot chain line X) to decrease to shadow Y and shadow Z, the ice storage sensor 33C does not detect insufficient ice storage. There is also a problem that it is difficult to restart ice making even though the ice is being taken out.

On the other hand, in the case of the configuration shown in FIGS. 7, 8 and 9, the ice storage state in the ice storage 27 is such that the bottom of the ice making section 1 rises as shown by the chain double-dashed line diagram M in FIG. That is, since the ice is stored in the ice storage 27 toward the right side when viewed from the front, when the door 29 is opened, the ice spills out or the door 29 opens naturally as shown in FIG. Is not resolved.

The present invention has been made in view of the above-mentioned problems, so that the ice does not spill when the door is opened, and when a front side ice is taken out, a predetermined amount of ice is quickly made to make additional ice. It is an object of the present invention to provide a downflow type ice maker designed for the above.

[0011]

The present invention provides a flow-down type ice making machine for circulating ice making water on an ice making plate which is provided with a cooling pipe and arranged substantially vertically to form ice on the ice making surface.
