Abstract
The utility model discloses a cool-escaping prevention food fresh-keeping refrigeration house which comprises a storeroom, a storeroom door, a refrigerating system and a self-control air curtain device, wherein the self-control air curtain device comprises an air curtain machine and an overtravel-limit switch; and the overtravel-limit switch is arranged on a door frame outside the storeroom door, and the air curtain machine is arranged in the storeroom and positioned above the inner side of the storeroom door. When the storeroom door is opened, cool air in the storeroom forms cool air curtains from top to bottom through the air curtain machine, so that the convection of cold air and hot air inside and outside the storeroom can be effectively prevented, and the intrusion of high temperature air outside and the escape of cool air in the storeroom can be avoided, thereby improving the refrigeration effect of the refrigeration house, reducing the load of a compressor and energy consumption, and prolonging the service life of the refrigerating system.
Description
Technical field
The utility model relates to freezer, more particularly, relates to a kind of anti-cold food fresh keeping freezer of escaping.
Background technology
Please in conjunction with Fig. 1, shown in Figure 2, at present, traditional food fresh keeping freezer 10 generally comprises storehouse 11, storehouse door 12, refrigeration system (not shown) and automatic control air curtain apparatus, the automatic control air curtain apparatus comprises air curtain 14 and travel switch 15, air curtain 14 is located at outside the storehouse 11, and being positioned at the top in storehouse door 12 outsides, travel switch is located on the outer doorframe of storehouse door 12.When storehouse door 12 is opened, travel switch 15 closures, air curtain 14 starts and utilizes the general air (being hot-air) of storehouse door 12 peripheries to form lasting downward thermal current, in order to leakage that prevents cold air in the storehouse and the intrusion of isolating hot gas outside the storehouse.But in actual use, because the temperature moment temperature difference is bigger in ambient temperature and the freezer, and what air curtain 14 formed is downward warm air curtain, in case therefore storehouse door 12 is opened the strong cold-hot air convection of easy formation, cause that cold air seriously runs off in the storehouse, and suffer the intrusion of external high temperature air, the rise and the temperature distributing disproportionation that cause temperature in the freezer, not only influenced the refrigerating effect and the fresh keeping time of preservation thing in the storehouse, but also cause the compressor moment high load capacity work of refrigeration system, shortened the service life of refrigeration system virtually, and increased electric energy loss, caused the certain economic loss to the user.
The utility model content
At the above-mentioned shortcoming that exists in the prior art, the purpose of this utility model provides a kind of anti-cold food fresh keeping freezer of escaping, this freezer can effectively prevent the inside and outside cold-hot air convection in storehouse, not only improves cold storage effect, but also prolongs the service life of refrigeration system.
For achieving the above object, the utility model adopts following technical scheme:
Should anti-escape cold food fresh keeping freezer and comprise storehouse, Ku Men, refrigeration system and automatic control air curtain apparatus, the automatic control air curtain apparatus comprises air curtain and travel switch, travel switch is located on the doorframe outdoors of storehouse, and described air curtain is located in the storehouse, and is positioned at the top of door inboard, storehouse.
Described air curtain comprises housing, motor, wind wheel and deflector, and the housing lower end is provided with air outlet, and motor links to each other with wind wheel and is located in the housing, and deflector is located at the air outlet place.
Described air curtain is tubular, centrifugal or the axial-flow type air curtain.
In technique scheme, of the present utility modelly anti-escape cold food fresh keeping freezer and comprise storehouse, Ku Men, refrigeration system and automatic control air curtain apparatus, the automatic control air curtain apparatus comprises air curtain and travel switch, travel switch is located on the doorframe outdoors of storehouse, air curtain is located in the storehouse, and is positioned at the top of door inboard, storehouse.When the storehouse door is opened, utilize cold air in the storehouse to form from top to down cool air curtain by this air curtain, can effectively prevent the inside and outside cold-hot air convection in storehouse, avoided the excessive of cold air in the intrusion of external high temperature air and the storehouse, thereby not only help improving the cold storage effect of freezer, but also alleviated the load of compressor, and reduced energy consumption, prolonged the service life of refrigeration system.

Fig. 1 is traditional freezer storehouse partial structurtes schematic diagram outdoors;
Fig. 2 is the cutaway view along A-A line among Fig. 1;
Fig. 3 is the partial structurtes schematic diagram of freezer Ku Mennei of the present utility model;
Fig. 4 is the cutaway view along A-A line among Fig. 2.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
See also Fig. 3, shown in Figure 4, it is of the present utility model that anti-to escape cold food fresh keeping freezer 20 basic identical with prior art, equally also comprise storehouse 21, storehouse door 22, refrigeration system (not shown) and automatic control air curtain apparatus, the automatic control air curtain apparatus comprises air curtain 23 and travel switch 24, travel switch 24 is located on storehouse door 22 doorframe outward, different is that this air curtain 23 is located in the storehouse 21, and is positioned at the top of storehouse door 22 inboards.This air curtain 23 comprises housing, motor, wind wheel and deflector, and the housing lower end is provided with air outlet, and motor links to each other with wind wheel and is located in the housing, and deflector is located at the air outlet place.By the driven by motor wind wheel, the cold air in the storehouse can be blown out downwards, thereby form cool air curtain.Need to prove that at this this air curtain 23 can adopt tubular, centrifugal or the axial-flow type air curtain.
When the storehouse of this freezer 20 door 22 is opened, travel switch 24 closures, start air curtain 23 and utilize the cold air formation cool air curtain from top to down storehouse in, be installed in the hot gas air curtain that freezer 10 air curtain 23 outdoors produced and compare with existing, cool air curtain in door can effectively prevent cold-hot air convection inside and outside the storehouse, better avoided the excessive of cold air in the intrusion of external high temperature air and the storehouse, thereby help not only guaranteeing that storehouse temperature is constant, improve the cold storage effect of freezer 20, prolong the fresh keeping time of chilled food, but also alleviated the load of refrigeration system compressor, reduced energy consumption, prolonged the service life of refrigeration system, also played dustproof certainly, anti-pollution, the effect of anti-mosquitos and flies; When the storehouse of freezer 20 door 22 was closed, travel switch 24 disconnected, and air curtain 23 is out-of-blast.
Need to prove that at this freezer of the present utility model prevents that escaping refrigeration technique not only is applicable to the food fresh keeping freezer, equally also is applicable to the freezer of other purposes.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
