Abstract

PURPOSE: To preserve a dry food at low moisture without requiring any desiccant for moisture absorption by coupling an airtight container for containing dry food through a duct to a dehumidifying section comprising a small tubular container disposed at the low temperature part of a refrigerator. CONSTITUTION: A cover 3 and a hermetically sealed section 4 are disposed at an upper part on the outside of an electric refrigerator 1 and an airtight container 2 blocking moisture in the outer air is provided. A dehumidifying section 8 comprising a small tubular container having a drain outlet 9 is disposed at the low temperature part of the refrigerator 1. The dehumidifying section 8 is coupled with the airtight container 2 through ducts 7, 7'. Since the moisture of air in the container is collected to the dehumidifying section through action of the partial pressure of steam and removed through condensation or freezing, dry foods contained in the airtight container can be preserved at low humidity without requiring any desiccant for moisture absorption.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electric refrigerator with a low-humidity container, and more particularly to an electric refrigerator with a low-humidity container suitable for storing dried foods.

[Conventional technology]

Conventional drying containers store dried foods by keeping the inside of the container at low humidity by adsorbing moisture to a desiccant through a chemical reaction or the like.

In addition, the inside of a conventional electric refrigerator is kept at low humidity because moisture is adsorbed on the surface of the freezer (approximately -19°C), but the temperature of the air inside the refrigerator is kept at a low temperature of approximately 3°C. Because it drips,
Theoretically, the relative humidity of the air should be about 14%, provided that no moisture is released from other stored foods and no moisture enters through gaps such as doors. However, in reality, moisture increases due to other foods or the intrusion of outside air, resulting in a dry container with even higher humidity.

[Problems to be solved by the invention] □The above conventional technology uses a desiccant in the drying container, so if the desiccant absorbs moisture, the moisture absorbing agent needs to be replaced.
No consideration was given to the need for time and effort to replace the desiccant, and if the replacement of the desiccant was delayed, there were problems such as increased humidity in the drying container. Furthermore, since the humidity inside an electric refrigerator is relatively high due to other foods and the intrusion of outside air, there is a problem in that when dry foods are stored, it is not possible to keep them perfectly dry.

The present invention has been made to solve the problems of the prior art described above, and aims to provide an electric refrigerator with a low-humidity container that can store dried foods and the like at low humidity without using a moisture-absorbing desiccant. This is the purpose.

[Means for solving problems]

In order to achieve the above object, the structure of the electric refrigerator with a low humidity container according to the present invention is to condense or freeze water vapor in the airtight container on the inner surface of a small tubular container provided in the storage section of the electric refrigerator. The container is equipped with a low humidity container connected to a dehumidifying section for removing moisture through a conduit.

[Effect]

Installed outside or inside the electric refrigerator. An airtight container with a sealed lid that does not allow moisture from outside air to pass through, and a dehumidifying section that removes moisture by condensing or freezing the water vapor in the airtight container on the inner surface of a small tubular container installed in the low temperature part of the refrigerator.
In a low-humidity container connected by a conduit, moisture in the air inside the airtight container is collected in a dehumidifying section by the action of water vapor partial pressure. As a result, the humidity of the air inside the airtight container decreases, so when dry food is stored in the airtight container, the dry food will not absorb moisture and the dryness of the dry food can be maintained at a high level. can.

(Examples) Examples of the present invention will be described below with reference to FIGS. 1 and 2.

First, FIG. 1 is a partially sectional perspective view of an electric refrigerator with a low humidity container according to an embodiment of the present invention.

The electric refrigerator shown in FIG. 1 is provided with an airtight container 2, which is equipped with a lid 3 and a sealing part 4 and does not allow moisture in the outside air to pass through, on the upper part of the outside of the electric refrigerator 1. A dehumidifying section 8, which is a small tubular container with a drainage hole 9 at the bottom, is provided in the low temperature section 5 in contact with or in the vicinity of the dehumidifying section 8, and the dehumidifying section 8 and the airtight container 2 are connected by conduits 7 and 7'. It is equipped with a low-humidity container configured as follows.

To explain its function, the dehumidifying section 8 removes moisture by condensing or freezing the water vapor in the air in the airtight container 2. When the water melts into water due to the action of the heater during defrosting, the conduit 7 and T are connected above the dehumidifying part 8 so that the water does not flow back into the airtight container 2.
A drainage hole 9 is provided at the bottom of the drain hole.

The electric refrigerator 1 is equipped with a heat insulating material 10 to maintain a low temperature inside the refrigerator.
However, the airtight container 2 provided outside the refrigerator receives heat from the outside air and is maintained at a temperature close to that of the outside air. Therefore, the temperature difference between the air inside the dehumidifying section 8 and the airtight container 2 becomes large.
The relative humidity of the air inside the airtight container 2 is assumed to be as follows: the temperature of the dehumidifying section 8 is -119 degrees Celsius, and the temperature of the air inside the airtight container 2 is +2 degrees Celsius.
When the temperature is 5°C, it becomes about 4% as generally determined from the psychrometric diagram at atmospheric pressure.

As described above, according to this embodiment, the humidity of the air inside the airtight container 2 is collected in the dehumidifying section 8, and the relative humidity of the air is lowered, and the dry air stored inside the airtight container 2 is Since the food does not absorb moisture and the dryness of the dried food can be maintained at a high level, it is effective in preserving the dried food for a long period of time.

In addition, conventionally, when dry food is stored inside an electric refrigerator, dew forms on the surface of the dry food as soon as it is removed from the electric refrigerator during the rainy season when the outside air is humid.
Moisture absorption often occurred, but in this example, the temperature of the air inside the airtight container 2 can be adjusted to a relatively high temperature, so there is an advantage that dew does not easily form on the surface of the dried food.

According to this embodiment, since the moisture in the air inside the airtight container 2 is continuously removed by the dehumidifying section 8, there is no need for a moisture-absorbing desiccant to be placed inside the drying container (airtight container).
Therefore, there is no need to replace the desiccant, and there is no need to manage the moisture absorption state of the desiccant.

Furthermore, by storing the dried food in the airtight container 2 of this embodiment, the air inside the airtight container 2 is dry, so there is an effect that the humidity can be kept low.

Next, FIG. 2 is a partially sectional perspective view of an electric refrigerator with a low humidity container according to another embodiment of the present invention.

The electric refrigerator 11 shown in FIG. 2 has an airtight container 12 equipped with a lid 13 and a sealed part 14 inside the refrigerator, and an electric cord heater 22 is placed outside in the low temperature part 15 inside the freezer of the electric refrigerator 11. A wrapped dehumidifier 18 is provided, a drain hole 19 is provided in the lower part of the dehumidifier 18, a conduit 17,17' connected to the upper part of the dehumidifier 18 is provided, and these conduits 17.
An electric sealing valve 24 is provided in the middle of each conduit 17 and 17', and the conduit 17 and 17' are passed through the heat insulating material 21 and connected to the airtight container 12.
is connected to.

20 indicates a heat insulating material of the electric refrigerator 11.

Since the airtight container 12 is installed inside the electric refrigerator 11, its temperature is low, so the temperature of the air inside is low and the relative humidity of the air is high. However, this airtight container 1
The airtight container 12 has an outer wall made of a heat insulating material 21, and a heating means 23 using an electric heater or high temperature gas discharged from a compressor (not shown) of an electric refrigerator is provided inside the airtight container 12. The relative humidity of the air inside 12 can be lowered.

In addition, instead of the heating means 23 such as the heater described above, it is also possible to omit the heating means by using the outer wall of the airtight container as a part of the outer wall of the electric refrigerator.

By providing a blower 25 in the middle of the conduit 17 to circulate the air inside the airtight container 12, the humidity of the air inside the airtight container 12 can be reduced more quickly.

According to the embodiment shown in FIG. 2, the same effects as those previously explained in the embodiment shown in FIG. 1 are expected.

In each of the above embodiments, the airtight container is installed outside or inside the electric refrigerator, but the low humidity container according to the present invention may be provided separately from the refrigerator.

If the refrigerator and low-humidity container are sold separately, seal the entrance of the conduit with a rubber stopper, etc., and connect the airtight container that makes up the low-humidity container and the dehumidifying section inside the refrigerator through the conduit during use. All you have to do is connect it.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to provide an electric refrigerator with a low-humidity container that can store dried foods and the like at low humidity without using a moisture-absorbing desiccant.
