Technical field

The utility model relates to household electrical appliance technical field, relates in particular to the refrigerator of a kind of multi-functional temperature-changing chamber and application thereof.

Background technology

Present known refrigerator is made up of refrigerating chamber and refrigerating chamber basically that (three-door refrigerator has increased temperature-changing chamber, temperature range: 0～-10 ℃), residing temperature range is respectively about 10 ℃ and below-18 ℃, the purposes of two Room is respectively: refrigerating chamber is mainly used to deposit vegetable and fruit etc.; Refrigerating chamber then is mainly used to deposit quick-frozen food, meat.As everyone knows, human body temperature is about 37 ℃, and the optimum temperature of needed by human body food is also near this temperature, therefore the food (the especially used dairy produce of infant) that takes out from refrigerating chamber need be incubated, and after the freezing food materials that refrigerating chamber takes out need to thaw especially, cook again, be incubated or thaw and often need realize by electrical equipment such as micro-wave ovens this time.Yet refrigerator is in the process of refrigeration on the other hand, and condenser can distribute heat greatly, and this part heat utilizes current not obtaining, and is just distributed merely.Can learn in conjunction with the above, if can utilize the heat that distributes in the refrigerator process of refrigerastion that the food materials that take out from the freezer chamber are carried out reverse alternating temperature (be incubated or thaw), can strengthen utilization efficiency of energy so undoubtedly, and lack this design just in the prior art.

The utility model content

The purpose of this utility model provides the refrigerator of a kind of reverse temperature-changing chamber and application thereof, to strengthen the efficiency of energy utilization of refrigerator.

In order to achieve the above object, the technical solution of the utility model proposes a kind of reverse temperature-changing chamber, is applied in the double-door refrigerator, comprises casing and inner bag, also comprises heat absorption fan and air channel; Described heat absorption fan is communicated with the condenser thermovent of refrigerator; Described air channel is provided with on the sidewall of described inner bag, and inlet one end in described air channel connects described heat absorption fan, exports an end and communicates with described casing outside air.

Above-mentioned reverse temperature-changing chamber also comprises: electrical heating wire is located on the sidewall of described inner bag.

Above-mentioned reverse temperature-changing chamber also comprises: temperature sensor is located in the sidewall of described inner bag.

For above-mentioned reverse temperature-changing chamber, described refrigerator is provided with control chip, and described heat absorption fan, described electrical heating wire and described temperature sensor all are connected to the control chip of described refrigerator.

The utility model also provides a kind of refrigerator of using reverse temperature-changing chamber, comprises refrigerating chamber and refrigerating chamber, it is characterized in that, also comprises aforesaid reverse temperature-changing chamber.

Technical solutions of the utility model are outside the freezer chamber of clamshell doors refrigerator (dual system), increase to be provided with and have the reverse temperature-changing chamber that is incubated/thaws function, its heat radiation to condenser for refrigerator is used, thereby strengthened the efficiency of energy utilization of refrigerator, also further expanded the purposes of refrigerator.

Description of drawings

Fig. 1 uses the schematic rear view of the refrigerator embodiment of reverse temperature-changing chamber for the utility model.

The specific embodiment

Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.

Fig. 1 uses the schematic rear view of the refrigerator embodiment of reverse temperature-changing chamber for the utility model, and as shown in the figure, the refrigerator of present embodiment has also been set up the reverse temperature-changing chamber 13 that the utility model proposes except that refrigerating chamber 11 and refrigerating chamber 12.

Further as shown in the figure, the reverse temperature-changing chamber 13 of present embodiment comprises casing 131 and inner bag 132, also comprises heat absorption fan 133 and air channel 134.Wherein, heat absorption fan 133 is communicated with the condenser thermovent 14 of refrigerator; 134 in air channel is provided with on the sidewall of inner bag 132, and the inlet one end 1341 connection heat absorption fans 133 in air channel, exports 1342 outside airs with casing 131 of an end and communicates.In addition, the reverse temperature-changing chamber 13 of present embodiment also comprises: electrical heating wire 135 and temperature sensor, and wherein electrical heating wire 135 is located on the sidewall of inner bag 132 and can be arranged on the 134 residing same sidewalls of air channel; Temperature sensor then is located in the sidewall of inner bag 132, and for fear of the air channel 134 and the interference of electrical heating wire 135 and reflect true temperature in the temperature-changing chamber 13 more accurately, temperature sensor preferably is located in air channel 134 and the electrical heating wire 135 residing different laterals, is also not show in scheming.

At last, above-mentioned heat absorption fan 133, electrical heating wire 135 and temperature sensor all are connected to the control chip (not shown) of refrigerator, thereby can utilize the control chip of refrigerator that the temperature of reverse temperature-changing chamber 13 is accurately controlled.

Below in conjunction with the foregoing description the major function and the course of work of the reverse temperature-changing chamber of the utility model are simply set forth.

1. heat insulation function relates generally to three big assemblies: the heat absorption fan 133 and the air channel 134 of the condenser of refrigerator and reverse temperature-changing chamber 13;
