Description

[Detailed Description of the Invention] The present invention relates to a dry box for dry storage of seaweed, rice crackers, and other foods that dislike moisture.

Conventionally, refrigerator-freezers are used for long-term storage of these items, but in this case, the stored items are cooled to about -15 to 18 degrees Celsius, so when they are taken out of the storage, condensation forms on the surface, causing condensation. As a result, products that have been dried at low temperatures end up becoming damp.

This invention ensures long-term storage by always storing the product in a dry atmosphere in a dry box.The drying atmosphere uses air that has passed through a drying cylinder filled with a dehumidifier, and also uses refrigeration to regenerate the dehumidifier. The waste heat of the condenser installed in the refrigerator is utilized, and the illustrated embodiment will be explained.

Reference numeral 1 indicates a known refrigerator-freezer having a freezer compartment 1a and a refrigerator compartment 1b, and 2 indicates a dry box that is integrally formed with the refrigerator-freezer 1 and partitioned at its lower part.The box 2 is not necessarily formed integrally with the refrigerator 1. Instead, it may be formed separately and placed on the top of the refrigerator.

3 is a drying box filled with a dehumidifying agent such as silica gel, and the drying box 2 and the drying box 3 are connected by a drying blower 4.
They were also connected by a circulation path with two switching valves 5 and 6 interposed therebetween.

One of the switching valves 5 is a three-way valve that is installed between the dry box 2 and the drying cylinder 3, and when the switching operation is performed, the secondary side of the drying cylinder 3 is switched between the dry box 2 and the atmosphere side. The other switching valve 6 is a dry box 2 and a drying blower 4.
and the air intake side of the blower 4 is connected to the dry box 2.
and a supply pipe 9 which exchanges heat with the condenser 8 of the refrigerator-freezer 1 and utilizes the waste heat to use the outside air as dry air for regenerating the dehumidifier, and connects the supply pipe 9 to the atmosphere side. It consists of a four-way valve that can be switched open, and a blower 7 is used to take in outside air as dry air for regeneration.
The capacity is for the pressure loss of the drying cylinder 3.

In the figure, reference numeral 10 indicates an outside air intake port for the regeneration blower 7 that opens at the lower front of the refrigerator-freezer 1, 11 indicates an exhaust port that opens the drying tube 3 and the drying air supply pipe 9 to the atmosphere, and 12
indicates an opening/closing damper provided between the dry box 2 and the switching valve 6, and 13 indicates a compressor of the refrigerator-freezer 1.

In addition, drying cylinder 3, blower 4.7, condenser 8, switching valves 5, 6
These devices are installed inside the outside air intake port 10 and the exhaust port 11.

Normally, the inside of the dry box 2 in this device is connected to the drying cylinder 3 by a circulation path as shown in the system diagram of FIG. Since the condition is maintained, the items stored inside are reliably stored in a dry condition, and the fourth
As shown in the figure, the drying tube 3 is separated from the dry box 2 by switching the switching valves 5 and 6 at the appropriate time, and the dehumidifier is dried by connecting it to the dry air supply pipe 9 connected to the regeneration blower 7. The moisture absorbing property is renewed and regenerated and used again for dry storage in the dry box 2.

In this way, according to the present invention, dry air is constantly circulated through the dry box 2 using a dehumidifier to store stored items in a dry state, and drying air for regenerating the dehumidifier is taken in from the outside. This moisture-proof article has the feature that it is extremely easy to regenerate and renew the moisture-wicking property because the air is heated and dried by exchanging heat with the condenser 8 installed in the refrigerator-freezer 1 and the waste heat is used. This has the effect of facilitating long-term storage.

Claims (1)

[Scope of utility model registration request] A dry box 2 provided integrally with the refrigerator-freezer 1 or separately from the refrigerator-freezer 1 and a drying tube 3 filled with a dehumidifier are connected to each other by a circulation path via a drying blower 4 and two switching valves 5.6. At the same time, by switching the two switching valves 5.6, the communication between the drying cylinder 3 and the drying box 1 is disconnected, so that the inside of the drying cylinder 3 is connected to the regeneration blower 7 and connected to the condenser 8 of the refrigerator-freezer 1. Regeneration dry air supply pipe 9 to be replaced
A refrigerator-freezer with a dry box connected to the
