The adjacent ice making recesses 4 are provided on the opening side of the ice making recesses 4 of the ice block frame 2.
In the ice tray with the groove-shaped flow passage 2 connecting the doshi, when a predetermined amount or more of water is poured into one ice making recess 4, the water is distributed to all the ice making recesses 4 constituting the ice making tray through the flow passage 2. It If left in this state in a subzero atmosphere for a sufficient time, the water will freeze. This process is called ice making.
After all the water is frozen, that is, when the ice tray is turned over and a twisting force is applied after the ice making is completed, the twisting force causes the ice in the portion of the running water channel 2 having a small cross-sectional area to be crushed, and at the same time, the ice tray is deformed and iced. A gap is created between the ice tray and the ice tray, and when the ice tray and the ice are completely separated, the ice falls.

The cross-sectional area of ice formed in the running water channel 2 is changed. Therefore, the ice formed in the flowing water channel 2 has a portion having a cross-sectional area smaller than the surrounding area, and when a twisting force is applied, stress concentrates on this portion. That is, the ice at the stress concentration point is crushed with a twisting force smaller than the surroundings. Therefore, the ice in the flowing water channel portion can be crushed with a twisting force smaller than that of the conventional ice tray, and the ice blocks can be individually taken out, so that the ice removal becomes easy.

Flow channel 2 configured in this way
The ice made in (1) has a cross-sectional area smaller than the surrounding area at the deepest part of the slope of the bottom of the flowing water channel 2, and is crushed by a smaller twisting force. Further, if the shape of the ice making concave portion 4 including the flowing water channel is widened from the lower part to the upper part, it is possible to mechanically move the ice including the ice in the flowing water channel part upward and separate it from the ice making tray. The obstacles can be reduced and the mechanical deicing resistance can be reduced. Therefore, the ice can be smoothly moved downward when the ice tray is turned upside down.

I am letting you. For this reason, the ice formed in the running water channel 2 at the time of ice making has a portion having a smaller cross-sectional area than the surrounding area, and when a twisting force is applied, stress concentrates on this portion. That is, the ice at the stress concentration point is crushed with a twisting force smaller than the surroundings. Therefore,
Ice can be crushed with a twisting force smaller than that of a conventional ice tray and each ice block can be individually taken out, so that ice removal becomes easy.

より容易にできる。Further, as shown in FIG. 4, in addition to changing the width of the flowing water channel 2, the cross-sectional shape of the flowing water channel 2 is increased from the lower part to the upper part, for example, the angles of θ 1 and θ 2 (when θ 1 = θ 2 You can spread it. The ice made in the running water channel 2 configured in this way has a cross-sectional area smaller than the surrounding area at the narrowest part of the bottom of the running water channel 2, and is crushed by a smaller twisting force. Further, if the shape of the ice making concave portion 4 including the flowing water channel is widened from the lower part to the upper part, it is possible to mechanically move the ice including the ice in the flowing water channel part upward and separate it from the ice making tray. There is no obstacle. Therefore, the ice can be smoothly moved downward when the ice tray is turned upside down. At this time, the ice in the ice tray falls due to gravity unless it is attached to the ice tray, so that only a force for separating the ice tray and the ice is required to remove the ice. In particular, when the ice tray is made of polypropylene or polyethylene as the material, it is easy to separate the ice and it is not necessary to crush the ice in the portion of the running water channel 2. The ice in the ice making recesses 4 may drop while being connected to the ice in the water flow channel 2, and the impact of the fall may destroy the ice in the water flow channel 2. However, even if the ice is connected in the ice storage box, it is not a big problem. In addition, ice removal can be performed more easily than before.
