Description

The utility model relates to household devices for storing vegetables, fruits and other agricultural products that maintain the storage temperature in the internal volume year-round (in the temperature range from -40 to + 40 ° C of outdoor air), and is intended for operation in unheated rooms, mainly in glazed rooms balconies and loggias of apartment buildings.

A device is known - a refrigerator for storing vegetables and fruits in urban-type apartments, operating year-round. This device is equipped with a refrigeration device, a heating element and forced ventilation means. (USSR Author's Certificate No. 1237877).

The disadvantages of this device are:

- design complexity;

- various temperature conditions in the volumes of the working chamber,

separated by a curtain;

- fire hazard due to the location of the pipe in the bottom under the heating element.

The prototype of the proposed device is a device for storing agricultural products, made in the form of a chamber having a bottom, a lid and multilayer insulated walls. This device comprises a camera, in the upper part of which there is a means for cooling the camera, and in the lower part, a heating device. A refrigerant (dry ice or ice from salt solutions) or a refrigeration unit was used as a means for cooling the chamber. In the summer, the camera operates as a refrigeration device, and in the winter, as a thermal container and provides a constant preset storage temperature (Description of the invention to the patent of the Russian Federation No. 20111331).

The disadvantages of this device are:

- the fact that, when used as a means for cooling the refrigerant, there is a need for constant monitoring of the flow of refrigerant and its regular addition.

- the fact that, when used as a means for cooling a refrigeration unit, the refrigeration unit is located inside the chamber on a height-adjustable hanging top shelf, which complicates the design of the refrigeration unit and makes it difficult to remove excess heat generated during operation of the refrigeration machine.

- the fact that the means for cooling the camera is located on the hanging upper shelf inside the camera, which leads to the loss of usable space of the camera.

- the fact that the heating device, made in the form of a stand, in which the heating elements are located inside the camera, which leads to the loss of usable space of the camera.

The operation of devices designed to store fruits and vegetables on balconies and loggias implies their transport to the place of operation through narrow doorways of balcony doors. This circumstance introduces restrictions on the dimensions of devices with a rigid body structure. The purpose of the utility model is to create a simple to manufacture, economical, safe and easy to maintain and repair household appliance for year-round storage of vegetables, fruits and other agricultural products, operated in glazed balconies and loggias of urban apartments, with dimensions that do not depend on the size of the doorways of the premises.

To solve this problem, a device is proposed comprising a camera, means for cooling the camera, a heating device, a temperature controller, a ventilation system, and shelves. The camera body is made prefabricated, consisting of heat-insulated walls and the bottom, interconnected in any way that allows you to perform the assembly-disassembly operation repeatedly, while maintaining the tightness of the camera and sufficient thermal insulation at the junctions of the components. The dimensions of the components allow them to be carried individually through the doorways of the premises. One of the walls serves as a chamber door. As a means for cooling, a refrigeration machine is used, which is built into one of the walls of the housing so that the heat absorber of the refrigeration machine is located on the inner side of the wall (directed towards the inside of the chamber), and the heat dissipator and other elements of the refrigeration machine are located on the outside of the same wall. The heat absorber may be part of the inner surface of the wall. A wall with a refrigeration machine built into it is a single refrigeration unit. The heating device is a heating panel, which is mounted on the inside (bottom of the chamber) of the bottom and is equipped with means for automatically disconnecting from the power source when the temperature rises above the set value, which excludes fire or smoldering of objects that have fallen on its surface. The heating device may be part of the inner surface of the bottom.

The proposed device has the following advantages:

1. Ease of maintenance.

2. Maximum use of the internal volume of the camera.

3. Lack of high qualification requirements during assembly.

4. The ability to repeatedly assemble, disassemble, transport from place to place, bring the device into the room in parts, with subsequent assembly at the place of use, which allows the manufacture of devices with cases of various configurations, the dimensions of which do not depend on the dimensions of the doorways of the premises.

5. The simplicity of the design and the absence of movable joints between the parts of the refrigeration machine due to the placement of all its elements on one wall of the housing.

6. High maintainability, low cost of repair, the possibility in the event of a breakdown of quick replacement or repair of the damaged part, and not the entire device.

7. Profitability due to the low power of the chiller, designed only for cooling the chamber without freezing food.

The device is illustrated in the drawing.

Figure 1 shows the device, a General view. Figure 2 shows the placement of the heat sink and shelves. Figure 3 shows the placement of the heat diffuser and the heating device. Figure 4 shows the placement of the temperature controller.

The device comprises a camera body, consisting of insulated walls 1 (four side and top) and bottom 2. One wall is made in the form of a door 3. A heat absorber 4 is placed on the inside of one of the walls (for example, top), and a diffuser is fixed on the outside 5. The evaporator and condenser of the compression refrigeration unit or the radiator of cold and the heat radiator of a thermoelectric refrigeration unit can serve as a heat absorber and heat dissipator. A heating device 6, made in the form of a heating panel, is fixed on the inner surface of the bottom. On the back wall there is a thermostat 7. Inside the chamber there are shelves 8.

The operation of the device is to maintain a constant year-round storage temperature of agricultural products in the internal volume of the chamber by turning on the heating device in the cold season, or turning on the chiller in the warm season, or completely shutting down both the chiller and the heating device.

In the cold season, at subzero temperatures not allowed for food storage, only a heating device works. In the warm season, the heating device turns off and only the chiller operates, maintaining the desired temperature for storing food in the chamber. In the autumn and spring periods of the year, when the ambient temperature is close to the storage temperature of the products, both elements are switched off. Control over the operation of the refrigeration machine and heating device is carried out automatically by a temperature regulator. When the temperature of the heating device reaches the safety threshold (the temperature above which further heating becomes unsafe), the own safety device of the heating device is activated and disconnects it from the power source.
