Description

[Detailed description of the invention] This invention relates to an ice making device that is suspended and supported in a cold air forced circulation refrigerator, which improves the cooling of the ice tray, eliminates the difference in ice making time between the rear and front sides of the ice tray, and This is an attempt to shorten the ice making time.

Conventionally, it has been known, for example, as disclosed in Japanese Utility Model Application Laid-Open No. 49-69461, that the rear surface of a freezing container, that is, an ice tray, which is placed in a freezing promotion chamber of a refrigerator, is formed with an inwardly inclined surface.

However, in the above-mentioned known ice tray, the ice tray covers a part of the cold air outlet, so the cold air that should be sent by the fan blocks the outlet and cannot enter the freezing promotion chamber, resulting in cooling. The rear surface is sloped inward to eliminate defects that adversely affect performance and defeat the original purpose of the refrigeration chamber.

In contrast, in this invention, the rear surface of the ice tray that is suspended is provided with an inclined part that extends to the vicinity of the bottom of the recess of the ice tray while sloping the rear surface of the ice tray to the outside. As described below (Figure 4), the cold air is introduced upward and flows through the space surrounded by the support and the ice tray to the front, so that it is sufficiently cooled to the front of the ice tray, and ice is made between the rear and front sides. The purpose is to eliminate the time difference and shorten the ice making time.

Further, to explain other conventional examples of ice trays that are suspended and supported, Fig. 1 is a perspective view showing the shape of a conventional ice tray, and Fig. 2 is a schematic vertical cross-sectional view of a portion of a conventional ice tray installed in a refrigerator. be. The ice tray 1 has a large number of independent recesses 2, and water can be poured into the recesses 2 and frozen to form ice particles. A conventional ice making method using an ice tray will be explained with reference to FIG.
That is, the ice tray 1 is supported by flanges 5 on both sides by a support 4 fixed to the upper part of the freezer compartment 3, and is installed facing the cold air outlet 7 of the partition plate 6. Here, the cold air cooled by the cooler 8 is blown out into the freezer compartment 3 from the cold air outlet 7 by a fan motor 9 and a fan 10 installed on the upper part of the cooler 8. At this time, the cold air hitting the back of the ice tray 1 is reflected as shown by the arrow and flows downward to the ice tray 1, so that the front side of the ice tray 1 is not cooled much. For this reason, there was a drawback that the ice making time on the front side of the ice making tray 1 was longer. This invention attempts to eliminate the above drawbacks.

FIG. 3 is a perspective view showing the shape of the ice tray 11 according to this invention, and FIG. 4 is a sectional view of the ice tray installed in a refrigerator. That is, as shown in FIG. 3, the ice making tray 11 according to this invention has independent recesses 2, and a portion of the surrounding flange 5 has an inclined portion 1 extending obliquely to approximately the bottom of the recess.
It has 2. As shown in FIG. 4, the inclined portion 12 is installed in the upper part of the freezer compartment 3 by means of a support 4 so as to face the cold air outlet 7. In this case, the cold air blown out from the cold air outlet 7 is
It is introduced upward as shown by the arrow, and flows through the space surrounded by the support 4 and the ice tray 11 to the front side.
For this reason, it is sufficiently cooled to the front of the ice tray 11,
This eliminates the difference in ice making time between the rear side and the front side, and has the effect of shortening the ice making time.

As described above, this invention eliminates the drawbacks of the conventional ice making device, has a simple structure, and has great practical effects.
