Abstract

PURPOSE:To prevent frosting at the upper front of a dual tank type ice making plate by providing an opening on a partition above the dual tank type ice making plate to check the upper part of the dual tank type ice making plate from being moistened at the start of making ice. CONSTITUTION:An opening 14a is provided on a partition 14 above a dual tank type ice making plate 10. As a result, moisture above the dual tank type ice making plate 10 is released through the opening 14a on the partition 14 to reduce moisture being carried to the upper front 13 of the dual tank type ice making plate on a cool air from a discharge port 5b. This enables the prevention of frosting at the upper front 13 of the plate.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a refrigerator having a two-tub ice tray for producing clear ice.

Conventional technology A refrigerator with a two-tank ice tray is the NR-D32V1 electric refrigerator released by Matsushita Electric Industrial Co., Ltd. in September 1989, but when making ice, frost forms on the upper front of the two-tank ice tray. There was an issue.

A conventional example will be explained below with reference to FIGS. 4 to 7.

As shown in the figure, 1 is the main body of the refrigerator. A freezer compartment is formed into sections in the main body 1, and 3 is a cooler provided at the back of the freezer compartment. Reference numeral 4 denotes a blower provided at the back of the freezer compartment 2, which distributes cold air cooled by the cooler 3 to the duct 4. 6 is a water storage box, and 7 is an ice tray, both of which are provided in the freezer compartment 2. 1o is a two-tank type box formed by an outer box 8 having an open top surface and having a plurality of four storage parts, and an inner box 9 having an open top surface and a plurality of ice-making recesses with holes 9a formed in the bottom. It's an ice tray. Reference numeral 11 denotes a partition plate that partitions the water storage box 6, the ice tray 7, and the two-tank ice tray 10. 5 is an opening provided in the duct 5 for discharging cold air to the freezer compartment 2, 5b is an outlet provided in the duct 5 for discharging cold air to the two-tank ice tray, and 12 is an opening provided in the lower part of the freezing compartment 2. A return air passage is provided.

In the above configuration, the cold air cooled by the cooler 3 is sent to the duct 5 by the blower 4, and in the duct 5, the opening 5a,
Cold air is distributed to the discharge port 6b.

The cold air coming out of the opening 6a circulates through the freezer compartment 2 and returns to the return air path 12. Further, the cold air discharged from the discharge port 6b also circulates above the two-tank ice tray 8 and returns to the return air passage 12.

Here, the two-tank ice tray 1o will be explained. The water in the inner box 9 gradually freezes from the top surface due to the cold air circulating above the two-tub ice tray 1o, and the air contained inside is discharged into the outer box 8 through the hole 9a. Therefore, transparent ice is made in the inner box 9, while ice containing air is made in the outer box 8.

Problems to be Solved by the Invention In such a conventional refrigerator, it is necessary to cool the two-tub ice tray 10 from above. If a large amount of cold air is sent above the two-tank ice tray 1o, the outer box 8 will also become cold, and ice will form on the top surface of the inner box 9 and from the outer periphery of the outer box 8, and ice containing air will Freezing occurs inside the inner box 9 and outer box 8. Therefore,
In order to make transparent ice in the inner box 9, a two-tank ice tray 10 is required.
It is necessary to prevent the outer box 8 from being cooled by reducing the amount of cold air sent upward. However, when the amount of cold air is reduced, the upper part of the two-tank ice making tray 1o becomes humid at the start of ice making, so there is a problem that frost forms on the front upper part 13 of the two-tank ice making tray.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a refrigerator that prevents frost from forming on the front upper part of a two-tank ice tray.

Means for Solving the Problems In order to achieve the above object, the present invention has an outer box having a freezer compartment, a plurality of storage recesses with an opening at the top inside the freezer compartment, and an outer box having an opening at the top and holes at the bottom. an inner box having a plurality of ice-making recesses formed therein, a two-tub ice-making tray formed by the outer box and the inner box, and a partition plate that partitions an ice-making corner for storing the two-tub ice-making tray. , a cooler provided at the back of the freezer compartment and a blower that blows air cooled by the cooler;
It is composed of a duct for distributing the cooled air, a discharge port provided in the duct at the back of the ice making corner, and an opening formed in the partition plate above the two-tub ice making tray.

Effect of the Invention The present invention has the above-described configuration, and since an opening is provided in the partition plate above the two-tank ice making tray, the upper part of the two-tank ice making tray is prevented from becoming humid when ice making starts, and the two-tank ice making tray is prevented from becoming humid. Frost formation on the front upper part of the plate can be prevented.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 3. Note that the same components as those in the conventional example are designated by the same reference numerals, and the description of the configuration will be omitted.

14 is a partition plate that partitions the water storage box 6, the ice tray 7, and the two-tank ice tray 10. 14a is an opening of a partition plate 14 provided above the two-tank ice tray 10.

In the above configuration, at the start of ice making, the moisture above the two-tank ice tray 10 is released through the opening 14a of the partition plate 14,
Reduces the humidity above the two-tub ice tray.

As described above, according to the refrigerator of the embodiment of the present invention, since the opening 14a is provided in the partition plate 14 above the two-tank ice tray 1o, the humidity above the two-tank ice tray 1o is reduced by the opening of the partition plate 14. Moisture suspended from the portion 14b and carried to the front upper part 13 of the two-tub type ice tray by the cold air from the discharge port 6b is reduced, and frost formation can be prevented.

Effects of the Invention As is clear from the above embodiments, according to the present invention, since an opening is provided in the partition plate above the two-tank ice making tray, it is possible to prevent the upper part of the two-tank ice making tray from becoming humid when ice making starts. To provide a cold air storage that prevents frost from forming on the front upper part of a two-tank ice tray.
