Description

[Detailed description of the invention] This invention divides the inside of the refrigerator with a partition wall to form multiple storage compartments, and one storage compartment is dried by directly circulating air cooled by a cooler using an electric blower. The present invention provides a refrigerator in which one storage compartment is provided, and the other storage compartment is maintained at an appropriate cooling temperature for storing vegetables, etc., which do not like to be dried.

Next, embodiments of the present invention will be described in detail based on the drawings.

1 is a refrigerator body formed by filling a heat insulating material 4 between an inner box 2 and an outer box 3, and the inside of the refrigerator is divided into three independent storage chambers 7, 8, and 9 by heat insulating partition walls 5 and 6. are doing.

The partition walls 5 and 6 may be molded integrally with the inner box 2.

A cooler 10 constitutes a refrigerant cycle and is housed in a cold air passage 11 within the partition wall 5.

The air cooled by the cooler 10 is directly circulated by a rear electric blower 12 through a cold air duct 13 to the storage chambers 7 and 8 to maintain the storage chamber 7 at freezing temperature and the storage chamber 8 at refrigeration temperature.

The temperature of the storage chamber 8 is maintained within a predetermined temperature range by a damper device 14 that detects the upper limit of the temperature of the storage chamber 8 and blocks cold air discharge from the duct 13.

A partition wall between the storage room 9 and the storage room 9 is formed by a heat-conducting plate 18 made of aluminum or the like, and the other surrounding areas are insulated by a heat-insulating partition wall 6 to allow air circulation. The empty space 15 is made adjacent.

This space 15 communicates with a cold air introduction path 16 into which a portion of the cold air in the cold air duct 13 is introduced, and a discharge path 17 through which the air in the space 15 is discharged to the storage chamber 8.

The storage room 9 is configured to control the flow of cold air introduced into the space 15.
A temperature detection device 19 detects the temperature inside the space 1 of the cold air introduction path 16 when this device 19 detects a predetermined upper limit temperature.
A temperature control device is provided, consisting of a damper device 20 closing the opening to 5.

The present invention is constructed as described above, so that the air cooled by the cooler is forcedly circulated directly to the storage chambers 7 and 8 to maintain it in a dry state.

On the other hand, the storage chamber 9 is cooled by the cold air introduced into the space 15 through the cold air introduction path 16, which cools the partition wall 18 of the heat conducting plate.

Since cold air to be cooled by the cooler 10 is not directly introduced into the storage chamber 9, the air in the storage chamber 9 is not dehumidified by the cooler 10.

Even if moisture in the storage chamber 9 is adsorbed to the thermally conductive plate 18 by cooling the thermally conductive plate 18 and condensation or frost occurs, the refrigeration cycle including the cooler 10 and the electric blower 12 cannot be operated.
When the operation of the storage chamber 7 is stopped by the temperature detection device of the storage chamber 7, or when the damper device 20 is closed and the intake of cold air is stopped, dew or frost on the heat conducting plate 18 is detected depending on the temperature of the storage chamber. Because of the evaporation, the storage chamber 9 can maintain an appropriate humidity and is suitable as a refrigerating chamber for foods that require an appropriate humidity, such as vegetables.

Furthermore, by providing doors that can be opened and closed independently in the front of each of the storage compartments 7, 8 and 9, it is possible to prevent a significant temperature rise in each compartment due to the opening and closing of the door of one of the compartments.

Moreover, each storage room 7, 8, 9. are insulated from each other, and the space 15 is also insulated from the storage rooms 7 and 8 other than the storage room 9, and the cold air in the cold air duct 15 is directly discharged into the space 15, so that each room is insulated from the other. Accurate temperature control is possible without being affected by temperature.

Conventional structures in which a vegetable storage container is installed in a refrigerator require a complicated structure with a gasket to ensure a sufficient seal with the lid of the container to prevent the inside of the container from drying out. On the other hand, the present invention does not require this and is superior in that it can maintain an appropriate temperature.
