Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of refrigerator, particularly a kind of air-breather of refrigerator.
Background technology
Refrigerator, due to the fresh-keeping and cold storage of its excellence and freezing function, plays obligato effect in the middle of daily life, and also due to the convenience that refrigerator uses, present large small merchant comprises domestic consumer and all adopts horizontal refrigerator storage food or Retail commodity.Therefore, the door on refrigerator just seems suitable important, no matter in appearance still structurally, meanwhile, due to refrigerator store or pulling items time, all relate to the enabling of refrigerator and close the door.But all there is a problem at the general refrigerator sold in the market, that is exactly when refrigerator is when normally working, after the door of refrigerator is opened a few minutes accessing article, shut the door again, after a few minutes, think to open door difficulty suitable sometimes again, trace it to its cause, mainly because in refrigerator case be an airtight space, after entering hot-air, then by cold events, the confined space air pressure in case is diminished, occur so-called " vacuum state ", thus cause refrigerator not open the phenomenon of door.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes a kind of air-breather of refrigerator, and it effectively can prevent the state occurring vacuum in refrigerator case, and cold air in refrigerator can be avoided again by this air-breather to be occurred the phenomenon of cold draining.
The purpose of this utility model realizes by following technical proposal: a kind of ventilation unit of refrigerator, described refrigerator comprises cabinet door, it is characterized in that, described ventilation unit comprises one and is arranged on the inside of cabinet door and the breather pipe that can be communicated with inside and outside refrigerator, the outer end of described breather pipe is connected with an enclosing cover, cover the sidepiece being connected to cabinet door outside described and there is an outer vent, described outer vent being provided with outer vent only can be made from the outer block toward interior one-way ventilating.
Breather pipe in the technical program is the unique passage inside and outside the casing of connection refrigerator, it can prevent the refrigerator under normal operating conditions once opening the door and close in a few minutes behind the door, because air in airtight case itself is caught a cold after-contraction, long vacuum state is there will be in case, thus cause refrigerator to occur not opening the phenomenon of door, its principle is, when the air in refrigerator case is by after cold events, in casing, pressure differential can be produced outward, air outside case can enter in the case of refrigerator via outer vent and breather pipe, make in the case of refrigerator, outer air pressure reaches balance, thus solve the problem not easily again opened in the cabinet door short time of refrigerator.
In the ventilation unit of above-mentioned refrigerator, described enclosing cover comprises the cover body part of a ring-type and the tracheae portion of a tubulose, described tracheae portion is arranged in the outer end inner chamber of breather pipe, described outer vent is positioned at the top in tracheae portion, described block comprises the cylinder that lid is located at the cap body on outer vent and can moves up and down along outer vent, has space between described cylinder and outer vent.Tracheae portion horizontally set, and between the top in tracheae portion and the inwall of breather pipe, there is space, the weight of dependence under normal conditions itself of blocking a shot seals on the outer outer vent covered, and when the case memory, external memory of refrigerator is in pressure differential, block moves up under pressure, air can flow in the space between cylinder and outer vent, thus make the inside and outside air pressure of the case of refrigerator reach balance, cylinder is used for carrying out spacing to the stroke of block, avoiding when ventilating, there is sidesway and deviates from outer vent in block.Block in the utility model also can be a check valve.
In the ventilation unit of above-mentioned refrigerator, the sidewall of described cylinder has down card.The card that falls is used for avoiding cylinder to deviate from outer vent outward by interior, and causes ventilation unit to lose efficacy.
In the ventilation unit of above-mentioned refrigerator, described cabinet door comprises door-plate and door inner bag, described breather pipe is be folded in the bend pipe structure between door-plate and door inner bag, breather pipe comprises the rectangular transverse tube of angle and vertical tube, the top of described vertical tube is connected with one end of transverse tube, and described enclosing cover is arranged on the other end of transverse tube, and the bottom of described vertical tube is provided with an inner cap in a tubular form, described inner cap is plugged on an inner bag from lower to upper, and the upper-end part of driving of inner cap is in the bottom inner chamber of vertical tube.Breather pipe is built in cabinet door, and structure is compacter, and aesthetic property is better, and inner cap is connected on an inner bag, and be connected with the inner port of breather pipe, the outside air that breather pipe imports can import in the case of refrigerator by it, ensures the air pressure balance that the case of refrigerator is inside and outside.
In the ventilation unit of above-mentioned refrigerator, the lower surface of described inner cap is closed, and the bottom sidewall of inner cap offers passage in several.On on the bottom surface that the interior passage be arranged on the sidewall of inner cap bottom can make the air imported directly act on an inner bag, air pressure balance better effects if.
In the ventilation unit of above-mentioned refrigerator, between described door-plate and door inner bag, be filled with polychlorostyrene fat foamed plastics.Polychlorostyrene fat foamed plastics, while positioning breather pipe, can also avoid breather pipe to leak gas, thus ensures that breather pipe can not lose efficacy when balancing the inside and outside air pressure of the case of refrigerator.
Compared with prior art, the utility model has following advantage:
1, the block in this device has the effect of check valve, makes device both can not affect the performance of refrigerator, can solve again refrigerator and to occur not opening the technical problem of door;
2, this device adopts the assembly relation of several little spare and accessory parts, installs simultaneously, has easy for installation, highly versatile, be applicable to all size refrigerator when freezer door body assembled formation;
3, this device is with low cost, aesthetic in appearance.
