Abstract
The utility model discloses a freezer with both an air cooling structure and a direct cooling structure. The freezer is characterized in that in the freezer, a blow-up evaporator is arranged on the front side of an inner container rear panel, a flat-plate-shaped cavity is formed between the blow-up evaporator and the inner container rear panel, two lateral edges of the flat-plate-shaped cavity are sealed to form a vertical air channel, an air channel inlet of the vertical air channel is located in the top portion of an inner container, air channel outlets are all horizontal through grooves which are formed in the blow-up evaporator at intervals, and a circular fan is arranged at the position of the air channel inlet so that air inside the freezer can flow in a forcing circulating mode through the vertical air channel. The freezer with both the air cooling structure and the direct cooling structure can not only satisfy quick and high-efficiency refrigeration of air cooling, but also complete heat exchange in a direct cooling mode without the need of forcing the air to flow, and an inverter compressor is arranged in a matching mode so as to realize high-efficiency refrigeration and achieve the purpose of saving energy.
Description
Technical field
The utility model relates to refrigerator and cooled and freezes case, a kind of heat exchange structure that relates to the refrigerator household freezer of more specifically saying so.
Background technology
At present, heat exchange has dual mode in the freezer compartment of refrigerator:
The one, air-cooled form, heat exchanger is evaporator fin, promotes air by blower fan and crosses the surface of evaporator fin at the air channel back warp, finishes heat exchange.The air channel of this situation is except export and import, and other parts are closed state.Heat in the refrigerating chamber is taken away by evaporimeter after relying on flow air to bring the air channel into, in this form, complicated air channel mechanism has taken certain volume, specifically arranging the efficiency influence of air channel is very big, blower fan works without cessation, and the heat-exchange system cost that is made of air channel, evaporator fin and blower fan is very high.
The 2nd, direct-cooled form, heat exchanger is fiber tube evaporimeter or the inflation evaporimeter in the box liner space; Or be close to the tube-in-sheet evaporator of inner bladder outer wall.This form does not have the forced air flow of blower fan, food by heat radiation and slowly cross-ventilation finish the exchange of heat between food and evaporimeter.Heat exchanging process is slow, and efficient is low.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of household freezer of holding concurrently air-cooled and direct-cooled structure is provided, can forced air flow realize fast-refrigerating by air-cooled heat exchange, can maintain in direct-cooled mode again under the required temperature conditions, simple in structure in the hope of obtaining, cost is low, can fast-refrigerating, resultant effect that result of use is good.
The utility model adopts following technical scheme for the technical solution problem:
The hold concurrently design feature of household freezer of air-cooled and direct-cooled structure of the utility model is: be provided with freezer drawer household freezer in, the front side that is positioned at the inner bag backboard arranges the inflation evaporimeter, between described inflation evaporimeter and inner bag backboard, form the tabular cavity, described tabular cavity forms a vertical air channel at dual-side for sealing, the air channel entrance in described vertical air channel is positioned at the inner bag top, the wind pass-out mouth in described vertical air channel is the horizontal groove in each road that is disposed on the described inflation evaporimeter, in porch, described air channel one circulating fan is set, the air in the household freezer is flowed by vertical air channel formation forced circulation.
The hold concurrently design feature of household freezer of air-cooled and direct-cooled structure of the utility model also is:
Described circulating fan is to start work when the difference of freezing the temperature inside the box and design temperature surpasses setting value.
The horizontal groove in described each road is separately positioned on position between the adjacent freezer drawer.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model is when circulating fan is devoted oneself to work, and forced air flow realizes the Rapid Thermal exchange, the efficient height, can realize fast-refrigerating;
2, the inflation evaporimeter exposes in household freezer in the utility model, and the inflation evaporimeter itself is the direct-cooled system of a cover, and under the situation that only needs holding temperature, circulating fan does not need to devote oneself to work, and the system works pattern is rationally effective;
3, it is low, more energy-conservation than air cooling system that the utility model is simple in structure, cost is compared air cooling system.
Description of drawings
Fig. 1 is the utility model structural representation;
Number in the figure: 1 household freezer; 2 circulating fans; 3 inflation evaporimeters; 4 vertical air channels; 5 horizontal grooves; 6 inner bag backboards.
The specific embodiment
Referring to Fig. 1, the household freezer air-cooled and direct-cooled structure of holding concurrently in the present embodiment is in household freezer 1, the front side that is positioned at inner bag backboard 6 arranges a slice inflation evaporimeter 3, between inflation evaporimeter 3 and inner bag backboard 6, form the tabular cavity, the tabular cavity forms a vertical air channel 4 at dual-side for sealing, the air channel entrance in vertical air channel is positioned at the inner bag top, the ducting outlet in vertical air channel is the horizontal groove 5 in each road that is disposed on the inflation evaporimeter 3, one circulating fan 2 is set in the porch, air channel, make the force air in the household freezer enter vertical air channel by the air channel entrance, and on the inflation evaporimeter, blowing out in as the horizontal groove 5 in each road of ducting outlet, form forced flow.
In concrete the enforcement, for the air-flow that makes ducting outlet is unobstructed, the horizontal groove 5 in each road should be to be separately positioned on position between the adjacent refrigerator drawer, flows in order to form between adjacent refrigerator drawer.
Circulating fan 2 is to start work when the difference of freezing the temperature inside the box and design temperature surpasses setting value, to realize fast-refrigerating; When the difference of freezing the temperature inside the box and design temperature is lower than setting value, close down circulating fan, the state of temperature of the direct-cooled system held refrigerating chamber that is constituted by the inflation evaporimeter.
The utility model can satisfy air-cooled fast, efficient cooling, also can finish heat exchange with direct-cooled mode under without the forced air flow situation, be equipped with frequency-changeable compressor and realize highly effective refrigeration, and reach energy-conservation target.
