Abstract

The utility model provides a multifunctional cold and heat insulation box which can refrigerate and heat simultaneously. A cold/heat converting chamber (2) is arranged inside a box body (1), and the upper part of the back wall of the cold/heat converting chamber is provided with a fan (13); an electric heater (14) is arranged just above the fan (13), and a baffle plate (12) is arranged for separating the fan and the electric heater from indoor space; the middle of the top surface of the baffle plate (12) and the middle of the bottom surface of the cold/heat converting chamber (2) are respectively provided with a hot blast inlet (16) and a hot blast outlet (15) which are communicated with the space behind the baffle plate (12), the cold/heat converting chamber (2) is also provided with a heating temperature controller (9). The cold/heat converting chamber (2) not only can refrigerate, but also can heat by conversion. Thus, the utility model can meet the requirement of food insulation of users in different seasons.

Description

The cold and hot incubator of using more

The utility model relates to a kind of hot and cold electric household appliance that is hidden in one of system that collects, particularly a kind of cold and hot incubators of using more.

Existing refrigerator has comparatively ideal storage space, but its function of having only refrigeration and keeping certain low-temperature condition, in different seasons, for example winter, refrigeration space relatively can be superfluous in the case, and simultaneously, People's Bank of China need carry out the space that heat is hidden to article.

The purpose of this utility model aims to provide a kind ofly cold and hotly many use incubator, satisfies the needs of people at the Various Seasonal insulating article, and a part of space of its refrigerator is set to cold and hot switch room, realizes the purpose that carry out simultaneously refrigeration and heat Tibetan.

The purpose of this utility model is achieved in that it is by casing, cold and hot switch room, refrigerating chamber and refrigerating chamber are formed, refrigeration system adopts the motor compression-type refrigeration, refrigeration modes is a direct-cooling type, at the casing internal upper part cold and hot switch room is set, fan is equipped with on its rear wall top, electric heater is housed under the fan, and there is a dividing plate that they and the cold and hot conversion interior space are separated by, crown center and middle part, cold and hot switch room bottom surface at dividing plate are respectively equipped with hot blast import and hot-blast outlet, being communicated with the space behind the dividing plate, the inner surface at the top of cold and hot switch room also is equipped with evaporimeter, heat is hidden temperature controller and electromagnetic valve circuit temperature controller.

What the utility model proposes cold and hot manyly use incubator, has realized the function of a tractor serves several purposes, is convenient for people to select needs that article are incubated in Various Seasonal.

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

Fig. 1 is the utility model structure chart.

Fig. 2 is the utility model section of structure.

Fig. 3 is the utility model schematic diagram of refrigerating.

Fig. 4 is the utility model circuit theory diagrams.

Among the figure 1; casing 2; cold and hot switch room 3; refrigerating chamber 4; refrigerating chamber 5; cold and hot switch room chamber door 6; refrigerating chamber chamber door 7; refrigerating chamber chamber door 8; 17; 18 evaporimeters 9; heat is hidden temperature controller 10; electromagnetic valve circuit temperature controller 11; rack 12; dividing plate 13; fan 14; electric heater 15; hot-blast outlet 16; hot blast import 19; condenser 20; refrigeration temperature control device 21; refrigeration switch 22; change-over switch 23; cabinet pin 24; refrigeration compressor 25; filter 26; capillary 27; three-way magnetic valve 28; unidirectional electrical magnet valve 29; liquid trap 30; overload protective device 31; PTC starter 32; lamp inside the box 33; attaching plug.

In Fig. 1, cold and hot switch room (2) is positioned at casing (1) internal upper part, in establish hot-blast outlet (15) and hot blast import (16), in refrigerating chamber (4), be provided with refrigeration switch (21) and change-over switch (22).

In Fig. 2, fan (13) is equipped with on the rear wall top of cold and hot switch room (2), be provided with electric heater (14) under the fan (13), and there is dividing plate (12) that they and the interior space are separated, be respectively equipped with the space after hot blast import (16) and hot-blast outlet (15) are communicated with dividing plate (12) at the crown center of dividing plate (12) and middle part, cold and hot switch room (2) bottom surface, the inner surface at the top of cold and hot switch room (2) also is equipped with evaporimeter (8), heat Tibetan temperature controller (9) and electromagnetic valve circuit temperature controller (10).In Fig. 3, the inlet of three-way magnetic valve (27) connects capillary (26), and an outlet connects evaporimeter (8), and another outlet connects evaporimeter (17); Unidirectional electrical magnet valve (28) is connected on the feed liquid pipeline between evaporimeter (8) and the evaporimeter (17), and this is in order to reduce the heat exchange between evaporimeter (8) and the evaporimeter (17) after cutting off when unidirectional electrical magnet valve (28).

In Fig. 4, form refrigerating system circuit by refrigeration compressor (24), refrigeration temperature control device (20), overload protective device (30), PTC starter (31), lamp inside the box (32), refrigeration switch (21) and attaching plug (33); Unidirectional electrical magnet valve (28) is in parallel with three-way magnetic valve (27) to be composed in series electromagnetic valve circuit with electromagnetic valve circuit temperature controller (10) again; Fan (13) is in parallel with electric heater (14) to be composed in series heat Tibetan circuit with heat Tibetan temperature controller (9) again; And it all is not get in touch with refrigerating system circuit respectively or relation in parallel with closure by the disconnection of change-over switch (22) that electromagnetic valve circuit and heat are hidden circuit.

The utility model operation principle: the plug that plugs in (33), refrigeration circuit is communicated with, refrigeration compressor (24) is started working, refrigerating chamber (3) and refrigerating chamber (4) refrigeration, when needs all freeze interior three spaces of casing (1), utilize change-over switch (22) that electromagnetic valve circuit is in parallel with the refrigeration system electricity; When needs are hidden cold and hot switch room (2) heat, when refrigerating chamber (3) and refrigerating chamber (4) freeze simultaneously, it is in parallel with refrigerating system circuit to utilize change-over switch (22) that heat is hidden circuit, at this moment, electric heater (14) and fan (13) are worked simultaneously, fan (13) is constantly sent the heat that electric heater (14) produces from hot-blast outlet (15), give cold and hot switch room (2) interior article heating, the gas that has carried out heat exchange flows into from hot blast import (16) again, after electric heater (14) heating, delivered in the cold and hot switch room (2) by fan (13) again, and can utilize heat to hide temperature controller (9) and regulate temperature.
