Abstract

The utility model relates to a refrigerator with a defrosting preserving room. The utility model is characterized in that the refrigerator is internally and independently provided with a defrosting preserving room which forms a cold wind circulating passage with an evaporator respectively through a wind inlet passage and a wind returning passage; a wind inlet and a wind returning port are respectively provided with a wind door; the defrosting preserving room is internally and independently provided with a heater and a temperature controller; the back of the heater is provided with a hot wind circulating fan; the hot wind forms internal circulation in the defrosting preserving room through a wind passage branch which is shortly connected between the wind inlet and the wind returning port. The utility model can defrost the frozen meat in a way of low temperature, mini wind and heating. After the deforsting, the meat still can be stored and preserved in refreshing temperature, so that the utility model can reduce the defrosting time and ensure the freshness degree of the meat.

Description

The refrigerator that has the fresh-keeping chamber that thaws

Technical field:

The utility model relates to the setting of refrigerator inside structure, more specifically says so to have the refrigerator of the fresh-keeping chamber that thaws.

Background technology:

At present, the defreezing method for the meat product by the refrigerator stored frozen comprises: place in the refrigerating chamber and thaw, be directly exposed to that air thaws naturally, water quickens to thaw.But these thawing modes have different shortcomings respectively, and wherein, the thawing rate that thaws in the refrigerating chamber is very slow, and thawing time is longer; The air thawing thawing time is long, and food is easily dry and contaminated, and it is inhomogeneous to thaw, and juice loss is big; Water thawing easily causes nutriment to run off and microbial contamination.Lose original freshness after these thawing modes thaw meat product, defrost result is not good.

Summary of the invention:

The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of refrigerator that has the fresh-keeping chamber that thaws is provided, the mode that adopts low temperature, gentle breeze and heating is to the frozen meat processing of thawing, thaw finish after meat still can remain in the preservation temperature and store, shorten thawing time, and guarantee the freshness of meat product.

The technical scheme that the utility model technical solution problem is adopted is:

Design feature of the present utility model is the independent fresh-keeping chamber that thaws that is provided with in refrigerator, and the fresh-keeping chamber that thaws is respectively by air inlet duct and air-return duct and evaporimeter formation cold wind circulation canal, and air inlet and return air inlet position are respectively arranged with air door; In the fresh-keeping chamber that thaws, heater and temperature controller independently are set, the heater back is provided with the hot air circulation fan, and hot blast forms interior circulation by the air channel branch road of short circuit between air inlet and return air inlet in the fresh-keeping chamber that thaws.

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

1, the fresh-keeping chamber that thaws in the utility model has concurrently and thaws and air-cooled fresh-keeping function.

2, the thaw realization of function of the utility model is at indoor formation circulating air, keep meat internal and external temperature basically identical in course of defrosting, quickened effectively the to thaw speed and the uniformity of thawing, thawing rate is 2～3 times that nature thaws, the back juice loss that thaws is few.

3, the utility model is by the requirement of thaw point, in finishing the storage temperature that still is kept at-7 ℃/0 ℃ after thawing, because the meat jelly node is-1～-5 ℃, ℃ therefore-7/0 ℃ temperature range is called as " single solution for diverse problems state ", the optimum state of promptly thawing, this temperature has effectively been avoided bacteria breed, prolongs storage life.

Number in the figure: 1 thaw fresh-keeping chamber, 2 air inlet ducts, 3 air-return ducts, 4 evaporimeters, 5 heaters, 6 hot air circulation fans, 7 air channel branch roads, 8 cold wind shutters, 9 cold wind return air doors.

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

The specific embodiment:

Referring to Fig. 1, Fig. 2 and Fig. 3, present embodiment is the independent fresh-keeping chamber 1 that thaws that is provided with in refrigerator, the fresh-keeping chamber 1 that thaws forms the cold wind circulation canal by air inlet duct 2 and air-return duct 3 with evaporimeter 4 respectively, air inlet and return air inlet position are respectively arranged with air door, comprise cold wind shutter 8 and cold wind return air door 9; In the fresh-keeping chamber that thaws, heating system independently is set, comprise heater 5 and temperature controller are set, heater 5 backs are provided with hot air circulation fan 6, and hot blast circulates in forming by the air channel branch road 7 of short circuit between air inlet and return air inlet in the fresh-keeping chamber 1 that thaws.

Shown in Figure 4, open cold wind shutter 8 and cold wind return air door 9, close air channel branch road 7 with cold wind return air door 9 simultaneously, stop the work of heater system, the fresh-keeping chamber 1 that thaws forms the cold wind circulation by air inlet duct 2, air-return duct 3 with evaporimeter 4, and chamber between 1 one-tenth refrigeration of fresh-keeping chamber thaws.

Shown in Figure 5, close cold wind shutter 8 and cold wind return air door 9, simultaneously air channel branch road 7 is also opened because of the change of the state of cold wind return air door 9, subsequently, heating system is devoted oneself to work, and hot blast forms inner loop by air channel branch road 7 in the fresh-keeping chamber 1 that thaws, the fresh-keeping chamber 1 that thaws the thawing room chamber.

Finish thaw after, the control refrigerating state is to keep thawing fresh-keeping chamber in-7 ℃/0 ℃ temperature range.

In concrete the enforcement,, can in the fresh-keeping chamber that thaws, place the soaking metallic plate in order to improve equal thermal effect.
