Abstract

A three-door refrigerator with food unfreezing function is characterized in that the refrigerator is in a three-room structure, one of the rooms can be a temperature-changeable unfreezing room, a circulated fan is arranged in the unfreezing room, and an unfreezing room temperature control system is independently arranged, an unfreezing evaporator branch circuit which is controlled by a magnetic valve and can be independently connected and disconnected is arranged, a defroster heater is assembled on the unfreezing evaporator, the unfreezing room temperature control system controls the work timeof the unfreezing evaporator and the defroster heater, the unfreezing temperature of 5-10 DEG in the unfreezing room is obtained, and the circulated fan in the unfreezing room keeps a running work state. The three-door refrigerator supplies proper unfreezing environment in the rooms of the refrigerator, is used for unfreezing frozen meat, shortens unfreezing time, and guarantees the fresh degreeof meat.

Description

The three-door refrigerator that has the food defrosting function

Technical field

The utility model relates to refrigerator, a kind of refrigerator with the function of thawing of more specifically saying so.

Background technology

Chinese eating habit is fresh, heavy mouthfeel, but the defreezing method that in the family chilled meat is used is mainly based on " thawing naturally or defreezing by microwave oven in the normal temperature air " at present, these thawing modes are because thawing time is long, perhaps temperature raises rapidly, causes the meat water loss serious, and the back meat product that thaws like this loses original freshness, defrost result is not good, the mouthfeel variation.The final mass quality of chilled meat not only depends on Refrigeration Technique itself, equally also depend on deforst technique, therefore need provide a kind of suitable temperature environment, make in the course of defrosting ice crystal in the meat be melted into water and absorbed by meat, thereby return to the fresh state before freezing, the fresh and mouthfeel before the reduction meat product is freezing.But present refrigerator does not have the function of the temperature environment that provides such.

The utility model content

The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of three-door refrigerator that has the food defrosting function is provided, indoorly between refrigerator provide the suitable environment that thaws, comprise be provided with environment temperature 5～10 ℃, be provided with wind speed≤1m/s gentle breeze, be provided with and can keep the nondecreasing humidity of surrounding air moisture in the course of defrosting, be used for the frozen meat processing of thawing, shorten thawing time, guarantee the freshness of meat product.

The utility model technical solution problem adopts following technical scheme:

The utility model has the three-door refrigerator of food defrosting function, is made of the refrigerant-cycle systems of each chamber and supporting setting, and its design feature is:

It is three cell structures that refrigerator is set, but one of them chamber is the defrosting room of alternating temperature, in described defrosting room circulating fan is set, and the defrosting room temperature control system independently is set;

Setting by solenoid control can independent break-make the evaporimeter branch road that thaws, on the described evaporimeter that thaws, be equipped with defrosting heater;

In the course of defrosting: the defrosting room temperature control system is controlled the working time of thaw evaporimeter and defrosting heater, obtains 5～10 ℃ of the interior thaw points of defrosting room, and keeping the interior circulating fan of defrosting room is the running duty.

Design feature of the present utility model also is:

In described three cell structures, be provided with the middle part between the chamber be defrosting room, the chamber is a refrigerating chamber between the top, the chamber is a refrigerating chamber between the bottom.

At described refrigerant-cycle systems, evaporator assemblies is set, described evaporator assemblies is three evaporimeter branch roads being selected conducting by magnetic valve, be respectively: the branch road A that constitutes by capillary A and defrosting room evaporator series, the branch road B that constitutes by capillary B, refrigerator evaporator and freezer evaporator series connection, and the branch road C that constitutes by capillary C and freezer evaporator series connection.

But the defrosting room of the utility model setting alternating temperature, in the course of defrosting, the heat cycles work of the refrigeration of the evaporimeter that thaws and defrosting heater, keeping the temperature of defrosting room is 5～10 ℃, cooperates the gentle breeze circulation to finish course of defrosting, thawing time is 1h～4h.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

The homogeneity of 1, thawing, the inside and outside of meat thaws synchronously in course of defrosting, and different parts has a narrow range of temperature;

2, thaw point is accurate and suitable;

3, the speed of thawing is 2～3 times of nature thawing time, and the back juice loss rate of thawing is little;

4, thaw when afterwards meat does not use for a long time, defrosting room will be adjusted storage temperature automatically and preserve.

Description of drawings

Fig. 1 is the utility model profile schematic diagram.

Fig. 2 is the utility model refrigerant system configurations schematic diagram.

Number in the figure: 14 refrigerating chambers, 12 temperature-changing chambers, 13 refrigerating chambers, 1 capillary A, 2 temperature-changing chamber evaporimeters, 3 capillary B, 4 refrigerator evaporators, 5 capillary C, 6 freezer evaporators, 7 reservoirs, 8 compressors, 9 condensers, 10 filters, 11 magnetic valves.

Below pass through the specific embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.

The specific embodiment

Referring to Fig. 1, in the present embodiment, it is three cell structures that refrigerator is set, but one of them chamber is the defrosting room of alternating temperature, and circulating fan is set in defrosting room, and the defrosting room temperature control system independently is set, circulating fan wind speed setting≤1m/s;

Setting by solenoid control can independent break-make the evaporimeter branch road that thaws, specifically adopt evaporator fin, on the evaporimeter that thaws, be equipped with defrosting heater, the power that defrosting heater is set is at 100～200W;

In the course of defrosting: the defrosting room temperature control system is controlled the working time of thaw evaporimeter and defrosting heater, obtains 5～10 ℃ of the interior thaw points of defrosting room, and keeping the interior circulating fan of defrosting room is the running duty, and thawing time is 1h～4h.

As shown in Figure 1, in three cell structures, the temperature-changing chamber 12 that is positioned at the middle part is set is defrosting room, the chamber is a refrigerating chamber 14 between the top, and the chamber is a refrigerating chamber 13 between the bottom.

Referring to Fig. 2, press the outlet of refrigerant flow direction from compressor 8, constitute refrigerant-cycle systems through condenser 9, filter 10, evaporator assemblies, reservoir 7 to the inlet of compressor 8 successively;

As shown in Figure 2, at refrigerant-cycle systems, evaporator assemblies is set, evaporator assemblies is three evaporimeter branch roads being selected conducting by magnetic valve 11, be respectively: the branch road A that constitutes by 2 series connection of capillary A 1 and defrosting room evaporimeter, the branch road B that constitutes by capillary B 3, refrigerator evaporator 4 and freezer evaporator 6 series connection, and the branch road C that constitutes by capillary C 5 and freezer evaporator 6 series connection.
