Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a refrigerator for preserving food that requires constant temperature.

Conventional technology In conventional refrigerators, the blower that stirs and blows cold air from the cooler to cool the storage compartment is installed on the windward side of the cooler.
Alternatively, it was installed parallel to the cooler on the leeward side.

An example of the conventional refrigerator mentioned above will be described below with reference to the drawings. In FIG. 4, reference numeral 1 denotes the main body of the refrigerator, which has a storage chamber 2 inside.
A cooler 3 is attached to the back wall of the storage chamber 2. 4 is a blower arranged on the leeward side of the cooler 3. A fan ring 5 is located on the outer periphery of the first blower 4 and is attached to the back wall of the storage chamber 2. 6 is a duct panel with an opening 6a at the top;
It has an opening 6b at the bottom and is located in front of the cooler 3, blower 4, and fan ring 5 to form an air path. Further, a compressor 7 and a condenser 8 are attached to the top surface of the main body 1, and together with the cooler 3, constitute a well-known cooling system.

The operation of the refrigerator configured as described above will be explained below.

First, when the compressor 7 is operated, the temperature of the cooler 3 decreases. As the blower 4 rotates, the air within the storage chamber 2 circulates as shown by the arrow. In the air path formed by the duct 6, air passes through the cooler 3, is cooled, and is discharged from the opening 6a to cool the food placed in the storage chamber 2.

Problems to be solved by the invention However, in the above configuration, the storage compartment 2
However, as it grows larger and more food is stored,
Since the air inside the storage room 2 circulates in only one direction, the air cooled by the cooler 3 and discharged from the opening above the duct exchanges heat with the food above the storage room 2, increasing its temperature. Since heat exchange is carried out with the food located below the storage chamber 2, there is a problem in that the temperature difference between the food located above the storage chamber 2 and the food located below the storage chamber 2 becomes large (3 to 6 degrees).

Therefore, the present invention aims to reduce the temperature difference between foods in a storage room.

Means for Solving the Problems The technical means of the present invention for solving the above-mentioned problems is to blow air into the storage room from an opening at the bottom of the storage room and to blow the air cooled by the cooler into the upper part of the storage room. It has a first blower that discharges air from the opening into the storage chamber, and a second blower that discharges air from below the storage chamber upward along one side of the storage chamber. The structure is such that the direction of air flow and the direction of air flow by the second blower are perpendicular to each other.

Effect The effect of this technical means is as follows.

In other words, convection occurs in a direction perpendicular to the flow of air cooled by the first blower attached to the main body and the second blower. Due to this convection in the right angle direction, the high temperature air in the lower part of the storage chamber is lifted up to the top of the main body and mixed with the air circulated by the first blower on the back of the main body, thereby suppressing the upper air from getting too cold. Moreover, since the cooled air from above flows downward through circulation by the second blower, it is mixed with the high temperature air after heat exchange from below.

Embodiment Hereinafter, an embodiment of the present invention will be described based on FIGS. 1 to 3. Components having the same structure as the conventional example are designated by the same reference numerals, and detailed description thereof will be omitted.

In the figure, 9 is a box body with a circular suction port 9 on the side.
a, and a discharge port 9b on the top surface. Further, the surface in contact with the storage chamber 2 is an open surface, and is attached with screws 12 so as to be in contact with the side and bottom surfaces of the storage chamber 2. A second blower 10 is attached to a bracket 11 with screws 13. Bracket 11
is attached to the box body 9 with screws 12 after the second blower 10 is attached. The second blower 10 is installed so that the direction of air flow is perpendicular to the direction of air flow caused by the first blower 4 above and below the storage chamber 2 .

The operation of the refrigerator configured as described above will be explained below.

When the second blower 10 rotates, air is sucked in through the circular suction port 9a on the side surface of the box body 9, and air is discharged along the side surface of the storage chamber 2 through the discharge port 9b on the top surface of the box body 9, as indicated by the arrow d. Generate the air flow shown. This air circulation flows in a direction perpendicular to the air circulation shown by arrow c which passes through the cooler 3 and is discharged from the fan ring 5 through the opening 6a of the duct plate 6, which is caused by the rotation of the first blower 4. This c
The high-temperature air that has exchanged heat with the food through the air circulation in the d-direction is lifted to the upper part of the low-temperature storage chamber and mixed therewith, thereby increasing the air temperature in the upper part. In addition, since the air in the upper part is flowed downward by the air circulation in the c direction, it is mixed with the higher temperature air in the lower part, and the higher temperature air in the lower part is cooled, and the temperature difference between the upper air and the lower air becomes smaller. As a result, the temperature difference between foods becomes smaller.

Effects of the invention The present invention consists of a first blower that blows air into the storage room from an opening at the bottom of the storage room and blows the air cooled by the cooler into the storage room from an opening at the top of the storage room; and a second blower that blows the air upward along one side of the storage chamber,
Since the upper and lower parts of the storage chamber are configured so that the direction of air flow by the first blower and the direction of air flow by the second blower are perpendicular to each other, the food in the upper part of the storage room and the food in the lower part of the storage room are separated. Temperature differences can be reduced. Moreover, since the air flow is not made faster to improve air circulation, food can be dried in the same way as conventional methods.
