Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a refrigerator equipped with a rapid cooling chamber and a thawing chamber for thawing frozen foods.

[Prior art]

If you want to quickly cool down beverages such as soft drinks and beer,
One possible method is to cool beverages by placing them in a freezer. However, if you forget to take it out, it will cool down too much, causing ice cubes and cracking of the bottle. Frozen foods can be thawed either naturally in a refrigerator, in the open air, or by heating in a microwave oven or the like. However, the former takes too long to thaw, and the latter has drawbacks such as rapid temperature rise, resulting in uneven thawing on the surface and center, and deterioration of freshness and taste.

[Purpose of the invention]

The present invention was developed in view of the above-mentioned drawbacks, and includes a thawing chamber and a quenching chamber within the refrigerator compartment, and a shutter that allows the selection of either cold air from the cooler or air inside the refrigerator. Our goal is to provide a refrigerator with a high quality.

[Summary of the invention]

In other words, by providing a shutter between the damper river 1 for controlling the temperature of the refrigerator room and the thawing chamber, the air in the refrigerator room can be sent only to the thawing chamber during thawing, and the cold air from the cooler can be sent only to the quenching chamber during quenching. It has been made possible.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. Reference numeral 1 represents the refrigerator body, and reference numeral 2 represents the inner box, which is formed from a synthetic resin plate by vacuum forming or the like. 3 is an outer box, which is formed by bending a metal plate or the like. The spaces of the inner and outer drawing boxes 2.3 are filled with a foaming heat insulating material 4 to form a heat insulating box body. 5 is a freezing room, which is a part for making ice or storing frozen foods. 6 is a refrigerating room, which is a part where general foods, vegetables, etc. are kept cool. The freezing compartment 5 and the refrigerating compartment 6 are divided by a partition wall 7. 8 is a freezer compartment door, which is connected to the freezer compartment 5.
The front opening 5a of the front opening 5a is closed.

Reference numeral 9 denotes a refrigerator compartment door, which closes the oil level opening 6a of the refrigerator compartment G. Reference numeral 110 denotes a cooler, which is installed at the rear of the freezer compartment 5 described in +'iif. This cooler 10 forms part of a series of refrigeration cycles and serves as a cold air supply source to the freezer compartment 5 and the refrigerator compartment 6. Reference numeral 11 denotes a fan, which is located above the cooler 10 and sends cold air generated by the cooler 10 to the freezer compartment 5,
Force cold air into refrigerator compartment 6! , i can be set. ]−
1a is a drive motor for rotating this fan 11. 12 is a cold air supply passage to the refrigerator compartment 6; a cold air discharge port 12;
a is located at the center of the back of the refrigerator compartment 6. Reference numeral 13 denotes a damper thermostat that senses the room temperature inside the refrigerator compartment 6 and adjusts the amount of cold air supplied to the refrigerator compartment 6 by opening and closing a damper. Reference numeral 14 denotes a thawing chamber installed in the refrigerator compartment 6, which can be used as a low-temperature chamber because it takes in part of the cold air from the refrigerator. Since the front part is open, it can normally be used as a refrigerating room. 16 is a pressure chamber provided between the damper thermostat 13 and the thawing chamber 14 and quenching chamber 15. 17 is the opening 11 of the pressure chamber 16 that opens and closes. It is a shutter that

During thawing, the shutter 17 or the discharge port 16a to the thawing chamber
The suction D16b from the refrigerator compartment is opened, and the discharge port 16c to the quenching compartment and the cold air suction 1016d from the damper are closed. Therefore, the air that passes through the damper and is discharged into the refrigerator compartment is
A portion of the liquid is discharged from the refrigerator compartment through the suction port 16b, discharged from the discharge port 16a to the thawing chamber 14, thawed with frozen foods, etc., sucked in from the suction lower a of the partition wall 7, and returned to the cooler 10. do. During rapid cooling, the shutter opens the discharge port 16G to the rapid cooling chamber and the cold air intake port 16d from the damper,
The discharge port 16a to the thawing chamber and the suction port 16b from the refrigerator compartment are closed. Therefore, most of the cold air that has passed through the damper passes through the cold air suction port 16C from the damper and is discharged from the discharge port 16d to the quenching chamber 15 into the quenching chamber 15, rapidly cooling beverages, etc. The air is separated into air that is directly sucked into the refrigerator, and air that is circulated within the refrigerator compartment and sucked into the suction lower a of the partition wall, and then circulated back to the cooler.

Furthermore, within the pressure chamber 16, a thawing chamber 14. A blower 18 is provided that acts on both the quenching chambers 15 and the speed of thawing and quenching can be accelerated by utilizing the wind speed.

〔Effect of the invention〕

As explained above, the present invention provides the following effects by providing a shutter between the damper and the thawing/quenching chamber provided in the refrigerator compartment. During thawing, the air inside the refrigerator is circulated into the thawing chamber, so there is no rapid temperature rise, so there is no uneven thawing or loss of freshness or taste.Also, since the air inside the refrigerator is used, the temperature can be kept in the refrigerator even during thawing. Does not affect room temperature. During rapid cooling, the cold air from the cooler that has passed through the damper is circulated into the rapid cooling chamber, allowing for rapid cooling.Since the cold air is used to cool the inside of the refrigerator compartment to around 3℃, this is due to the relationship with the heat capacity of beverages, etc. There is no need to worry about freezing due to forgetting to take it out. In addition, the cold air that has circulated through the quenching chamber also circulates inside the refrigerator, so it does not affect the temperature of the refrigeration chamber even during quenching.

Furthermore, by providing a blower that acts on the compartment, thawing and rapid cooling can be promoted.
