Abstract

PURPOSE:To centralize food storage places, and to preserve food for a long time period by keeping the inside of a storage dry, by a method wherein a refrigerator and a storage consisting of a refrigerating cycle, a fan and a temperature controller are installed side by side. CONSTITUTION:A refrigerator 1 and a storage 11 coincide with each other in their outside dimensions, height and depth, and are connected by joint plates 35 and screws 36. The storage 11 is also provided with a refrigerating cycle consisting of a compressor 16, an evaporator 17, a condenser and a pressure reducer, and a fan 18. When cold air cooled by the evaporator 17 is sent to compartments 12, 13 and 14, the air flow rate of the fan 18 is reduced compared with conventional freezer-refrigerators having the same capacity, and the surface area of the evaporator 17 is adjusted so that the temperature difference between the surface temperature of the evaporator and each compartment temperature (10-15 deg.C) is kept within a range of 20-30 deg.C. That is, the surface temperature of the evaporator 17 is constantly maintained below 0 deg.C, and the moisture in each compartment is frosted so as to keep the inside of the compartments dry steadily. The temperature of each compartment is maintained at 10-15 deg.C by controlling the compressor 16 and the fan 18 by a temperature detector 20 installed in the upper compartment 12.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a refrigerator that has storage chambers with a plurality of temperature differences and is capable of storing a wide variety of foods at appropriate temperatures.

Conventional technology Recent refrigerators have not only diversified food materials themselves due to diversification of dietary habits, but also preservation methods have diversified, such as preserving fresh foods such as fish and meat at appropriate food storage temperatures. ing. In addition, while the size of devices is increasing due to increased storage capacity, such as when purchasing frozen foods in bulk, there is a growing desire to reduce the installation space as much as possible due to housing circumstances.

On the other hand, samples that require cooling for preservation of foods necessary for daily life are generally stored in refrigerators, and other foods are stored in food storage cabinets.

Due to this background, conventionally there were multiple storage rooms, each with its own temperature controlled cold RN, and food storage with appropriate storage shelves located here and there in the kitchen. They are set up separately.

In the example above, the storage locations for essential foods are scattered throughout the kitchen, which is inefficient and makes it unclear where essential foods are stored. .

In addition, inventory management is difficult because necessary items are not available or unnecessary items are duplicated, making it unclear or uneconomical. Furthermore, the food storage devices installed in the kitchen and the refrigerator are different in size and depth, and when installed side by side, some devices stick out, and the heights are different, making it difficult to use. In addition, there are problems such as the difference in surface material and structure, making it unsightly.

In order to solve these problems, it is necessary to consider the method of installing a refrigerator and food storage together, the dimensions of the refrigerator and food storage,
In other words, the dimensions such as height and depth are made the same. It is also possible to match the surface materials and configurations and install them together.

Problems to be Solved by the Invention However, the foods stored in food storages other than refrigerators include dried foods, instant noodles, flour, dried noodles, canned foods, ready-to-eat foods, snacks, green tea, coffee beans, There are spices, seasonings, etc., and these various miscellaneous foods have unique properties, so adding chilled foods and rhinoceros together is not a solution.

However, storage of dried food in a dry state or general storage does not yet have a cooling function, so temperature factors such as high temperatures or temperature fluctuations may accelerate the deterioration of food. There is.

As mentioned above, in the conventional example, 1. If you try to store all kinds of foods together in the same place, the unique flavor of the food will also transfer with the transfer of moisture etc., causing mutual deterioration. ing.

On the other hand, due to the high temperature and high humidity conditions in the kitchen, there are concerns about oxidation, loss of vitamin C, moisture absorption, deterioration of flavor, etc. during food storage, which are not good storage conditions for food.

The present invention solves the above-mentioned problems of the conventional example, and preserves a wide variety of frozen and refrigerated foods well, and prevents other foods from oxidation, loss of vitamin C, moisture absorption, deterioration of flavor, etc. The purpose is to preserve food for a long time.

Means for Solving the Problems In order to solve the above problems, the present invention has a plurality of storage chambers, each of which is formed of a refrigerator body whose temperature is independently controlled, and an insulated box. A dry storage room, a storage room equipped with a refrigeration cycle for cooling the dry storage room, a blower for forced ventilation, and a temperature control device, including size, depth dimension, height dimension, and surface material configuration. In addition, the storage compartments are installed on either the left side or the right side of the refrigerator, or on both sides of the refrigerator.

Function: With the above-described configuration, the refrigerator and the storage adjacent to the refrigerator are not connected in parallel. By arranging them in series, food storage areas can be consolidated. frozen.

For food storage other than cold storage such as refrigeration, air cooled by a cooler is circulated within the storage using a blower, while a temperature control device is used to maintain the temperature inside the storage at 10 to 16°C. . Moreover, the inside of the storage can be dried due to the dehumidifying effect of the cooler.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 3.

In FIG. 1, the refrigerator main body 1 has a plurality of storage compartments, and the upper part is a freezer compartment 2, with a freezer compartment 2a on the right.

This is Frozen Declaration 2b. 3 is a refrigerating room having double doors 4; 5 is a low-temperature room with a pull-out compartment. θ
The vegetable compartment has a pull-out interior. The cold room 6 and the vegetable compartment 6 have a storage capacity (not shown) for storing food.

In the refrigerator 1 having such a configuration, each storage compartment performs independent cooling/temperature ifG control (cooling device).

The temperature control device is not shown), and the set temperature is -1 for freezer compartment 2.
The temperature of the refrigerator compartment 3 is set at 8°C, the temperature of the cold room 4 is set at -3°C for partial freezing, which is particularly effective for preserving fresh fish, and the temperature of the vegetable compartment 6 is set at 8°C for preserving vegetables.
In some cases, we also store bottles.

Next, 11 is a storage main body, which has an upper chamber 12, a middle chamber 13, and a lower chamber 14. As shown in FIG. 2, the cross-sectional view of the storage 11 is divided into an upper chamber 12, a middle chamber 13, and a lower chamber 1 by a partition plate 15.
It is divided into 4. 1θ is a compressor, and 17 is an evaporator, which together with a condenser and a pressure reducer (not shown) constitute a refrigeration cycle. A blower 18 sends cold air to each room (12, 13, 14).

19 is a heater installed on the back side of the upper chamber 12 and the lower chamber 14;
o is a temperature sensor that controls quadrupling of the compressor 16 and blower 18.

Reference numeral 21 denotes a storage container provided in the middle chamber 13, which is constructed to be a substantially airtight structure with the lid body 22 fixed to the middle chamber 13i1111 as the main part, and is supported by the door body 24 so as to have front and back sides. It is movable to open and close.

The operation of the storage 11 configured in this way will be explained.

The upper chamber 12 in the food storage 11 stores food that requires drying, and is equipped with a compressor 16, an evaporator 17,
The cold air cooled by the evaporator 17 is sent to each room by a refrigeration cycle consisting of a condenser, a pressure reducer (not shown), and a blower 18. Here, the air volume (circulation volume) of the transport louse 18
compared to a frozen cold MW of the same capacity! ,'s −k,
Also, the surface area of the evaporator 1T is controlled, and the temperature difference between the surface temperature of the evaporator 17 and the temperature of each chamber (10 to 15°C) is set to 20-3.
It is set to 0 dog. In other words, the surface temperature of the evaporator 17 is always negative, causing the moisture inside the food storage to form a sheath as frost, thereby stably maintaining the dryness inside the storage. In addition, the temperature inside each room is determined by controlling the operation of the compressor 16 and the blower 18 using a temperature detector 20 installed in the upper room 12.
Maintain stable temperature between 0 and 16°C.

Furthermore, even when the ambient temperature is low, an outside temperature detector (not shown) energizes the heater 19 at a certain temperature (for example, 16° C.) or below to apply heat to each room and operate the refrigeration cycle and blower. This makes it possible to maintain stable dryness in the refrigerator even when the ambient temperature drops.

Furthermore, the middle chamber 13 has a sealed structure, so that cold air does not directly enter the storage container 21, and the inside of the storage container B; 421 is kept at high humidity due to moisture evaporated from the stored vegetables, fruits, etc. It is also possible to preserve vegetables and fruits that require certain conditions for a long period of time.

Next, each room door 30.3M, 32, 33.3 of refrigerator 1
4 and the doors 23, 24, and 25 of each room of the storage 11 are made to match the height positional relationship, surface material, and 4 composition, and the external dimensions, height dimensions, and depths of the refrigerator 1 and the storage 11. Matching dimensions.

Furthermore, as shown in FIG. 3, the refrigerator 1 and the storage 11 are interconnected by screwing them to the ceiling and bottom of the refrigerator 1 and the ceiling and bottom of the storage 11 using a connecting plate 35 and screws 36. I'm letting you do it.

With this configuration, a refrigerator having a plurality of storage chambers and a storage having a cooling function can be installed in parallel on the same plane.

Effects of the Invention As is clear from the above explanation, according to the present invention, the following effects can be obtained.

(1) By keeping the inside of the storage room dry, food oxidation, moisture absorption, and deterioration of flavor can be prevented.

(2) Even vegetables and fruits that cause low-temperature damage when stored in conventional vegetable cases can be stored favorably by keeping them at 10 to 15° C. and high humidity.

(3) By maintaining dry conditions within the storage thickness, the transfer of odors between foods is reduced, and various foods can be stored in the same place.

(4) 1o, which is said to be the ideal storage temperature for food stored at room temperature
By storing foods at temperatures of ~15°C, oxidation, loss of vitamin C, deterioration of flavor, etc. promoted by high temperature conditions are reduced, and foods can be stored in good condition for long periods of time. Also, compared to refrigeration, the medium temperature of 10 to 16°C has the advantage of having a smaller difference from room temperature and less chance of condensation occurring when taking out spoiled food.

(@ Refrigerator and storage can store foods scattered around the kitchen in the same place, making it easier to manage inventory by storing them in bulk.

(6) Refrigerators and storage units can be uniformly installed, and a device with matching surface material composition and harmonized design can be obtained.
