Abstract

A freezer, icebox and display cabinet for refrigerating or heating the articles contained in the freezer, icebox and display cabinet, comprising two structural forms, wherein one structural form is a refrigerating and heating integral body formed by two inner containers, and simultaneously has functions of refrigerating and heating. The other structural form is the single inner container which achieves the exchange of refrigerating and heating, and changes the flow direction of the refrigerant through a four-port valve.

Description

Refrigeration heating dual-purpose type refrigerator-freezer, refrigerator, showcase

Affiliated technical field

The utility model relates to the article of depositing in a kind of space that can form thermal insulation layer and carries out thermoregulator device, especially can be to refrigerator-freezer, refrigerator, the showcase of the heating such as food and drink of leaving its inside in.

Background technology

At present, known refrigerator-freezer, refrigerator, showcase mainly are made up of the object space of depositing that evaporimeter, condenser, compressor, expansion valve, thermal insulation layer form.Evaporator coil is installed in deposits in the object space (being inner bag), or closely contact, and can carry out heat exchange preferably with inner bag.Its operation principle is the refrigerant liquid vaporization in the evaporimeter, by draining into condenser after the compressor suction compression, and the heat of evaporator coil, inner bag and the article deposited brought to condenser, carry out becoming high pressure liquid refrigerant after the heat exchange with external environment, after the expansion valve throttling, form low temperature, low pressure damp steam and enter evaporimeter and begin new round circulation.Present known refrigerator-freezer, refrigerator, showcase are mainly used in to the article cooling that is put in wherein, but do not possess the function that the article that are put in are wherein heated.

Summary of the invention

In order to overcome the deficiency that existing refrigerator-freezer, refrigerator, showcase only possess this simple function of refrigeration, the utility model provides a kind of refrigerator-freezer, refrigerator, showcase, and the article that can internally put freeze or heat, to adapt to different requirements.

The beneficial effects of the utility model are can dual-use, the internal memory article are freezed or heat, especially when heating, owing to belong to heat pump-type system, generally, when the same heat of internal memory materials supply, power consumption only is equivalent to adopt the 25%-50% of electric heating heating power consumption, energy-saving effect is obvious, and simple in structure.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is the fundamental diagram of common refrigerator-freezer, refrigerator, showcase.

Fig. 2 is the fundamental diagram of first embodiment.

Fig. 3 is the fundamental diagram of second embodiment.

1. compressors among the figure, 2. evaporimeter, 3. expansion valve, 4. condenser is an inner bag by the object space of depositing that thermal insulation layer forms 5., 6. valve, 7. valve, 8. valve, 9. valve, 6-9 can be combined into one becomes a cross valve.

Embodiment

The principle that Fig. 1 represents for common refrigerator-freezer, refrigerator, showcase, a cold function of tool list.

Among the embodiment shown in Figure 2, if two inner bags, place inner bag as refrigerating part in evaporimeter, place the another inner bag as heating part condenser, two inner bags should be heat insulation good, separately door or lid are set simultaneously, and this embodiment can make device possess refrigeration simultaneously and heat two kinds of functions.

Among second embodiment shown in Figure 3, the basic structure that keeps common refrigerator-freezer, refrigerator, showcase, just increased a cross valve (manually or Electromagnetic Control all can), when valve 6, valve 7 are opened, with valve 8, when valve 9 cuts out, refrigerant flow direction is counterclockwise in the system, and be evaporimeter this moment 2,4 is condenser, and this moment, device freezed over against the internal memory article; When valve 6, valve 7 are closed, with valve 8, when valve 9 is opened, refrigerant flow direction be clockwise in the system, and this moment 2 becomes condenser by evaporimeter, and 4 become evaporimeter by condenser, and device heats over against the internal memory article at this moment.

Claims

1, a kind of refrigerator-freezer, refrigerator, showcase not only can be to the article refrigeration cool-downs of internal memory but also can be to its heat temperature raising.

2, according to claim 1, two inner bags possess refrigeration, two kinds of functions of heating simultaneously.

3, according to claim 1, single inner bag by cross valve conversion refrigerant flow direction, thereby is selected inner bag is deposited thing refrigeration or heating.
