Diameter, described valve body side is provided with the first permeability cell being connected with described lower channel bottom, the mouth of pipe of described first permeability cell
Place's grafting is provided with first and breathes freely lid, and described valve body opposite side is provided with second be connected with described upper channel top and breathes freely
Pipe, at the mouth of pipe of described second permeability cell, grafting is provided with second and breathes freely lid, and described first breathes freely lid and the second permeability cell
Cover and be equipped with air-vent.
Described valve body is provided with opening at described upper channel top, and described opening part is sealed by top port lid.
In the foaming layer of the box house that described valve body is installed to refrigerator-freezer, and outside the mouth of pipe connection of described first permeability cell
Boundary, the mouth of pipe of described second permeability cell connects described refrigerator-freezer inner space.
It is arranged over positioning boss in the same side being positioned at described first permeability cell, the cabinet shell of refrigerator-freezer on described valve body
On be correspondingly arranged on the hole, location matched with described positioning boss, by described positioning boss is placed in described cabinet shell
Location positions in hole.
This utility model has the advantage that compared to existing technology
A kind of ventilating valve apparatus being applied to refrigerator-freezer that this utility model provides, can be automatically by silica-gel sphere GRAVITY CONTROL
Realizing connection and the closedown of vent valve, when forming negative pressure in refrigerator-freezer, vent valve automatically opens up, it is achieved pressure release, and because of permeability cell
The mouth of pipe relatively big, pressure release effect is obvious, and the time that freezer door is opened shortens several times；The vent valve when not forming negative pressure in refrigerator-freezer
Close, effectively prevent cold draining and steam cohesion, it is to avoid lining mouth frost.Directly insert additionally, permeability cell uses with ventilative lid
Connecing installation, assembly or disassembly is all convenient easily, it is simple to after-sales service.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the A-A sectional view of Fig. 2.
Label in figure: 1 valve body, 11 upper channels, 12 lower channels, 13 first permeability cells, 14 first breathe freely lid, and 15 second is saturating
Trachea, 16 second breathe freely lid, 17 top port lids, 18 positioning boss, 2 silica-gel spheres.
Detailed description of the invention
Elaborating embodiment of the present utility model below, the present embodiment is being front with technical solutions of the utility model
Put and implement, give detailed embodiment and concrete operating process, but protection domain of the present utility model does not limits
In following embodiment.
See Fig. 1 to Fig. 3, present embodiment discloses a kind of ventilating valve apparatus being applied to refrigerator-freezer, including valve body 1, valve body 1
Inside setting gas passage, gas passage includes upper channel 11 and lower channel 12, and upper channel 11 diameter is more than lower channel 12 diameter and shape
Become up big and down small step, in upper channel 11, be provided with silica-gel sphere 2, the diameter of silica-gel sphere 2 more than lower channel 12 diameter and
Less than the diameter of upper channel 11, valve body 1 side is provided with the first permeability cell 13 being connected with lower channel 12 bottom, the first permeability cell
At the mouth of pipe of 13, grafting is provided with first and breathes freely lid 14, and valve body 1 opposite side is provided with second be connected with upper channel 11 top
Permeability cell 15, at the mouth of pipe of the second permeability cell 15, grafting is provided with second and breathes freely lid 16, and described first breathes freely lid 14 and
Two breathe freely is equipped with air-vent in lid 16.Valve body 1 is provided with opening at upper channel 11 top, and opening part is close by top port lid 17
Envelope.
Wherein, in the foaming layer of the box house that valve body 1 is installed to refrigerator-freezer, and outside the mouth of pipe connection of the first permeability cell 13
Boundary, the second permeability cell 15 the mouth of pipe connection refrigerator-freezer inner space, arrange first breathe freely lid 14 and second breathe freely lid 16 be for
It is easy to and casing is installed.It is arranged over positioning boss 18 in the same side being positioned at the first permeability cell 13, the case of refrigerator-freezer on valve body 1
The hole, location matched with positioning boss 18 it is correspondingly arranged on, by positioning boss 18 is placed in determining of cabinet shell in body case
Position positions in hole.
When refrigerator-freezer external and internal pressure is identical, silica-gel sphere 2 falls because of gravity, upper channel 11 and lower channel 12 is isolated,
Now the first permeability cell 13 does not connects with the second permeability cell 15, and vent valve is closed, and can intercept gas circulation inside and outside refrigerator-freezer, reduce
Cold draining.When producing negative pressure i.e. air pressure inside less than external pressure in refrigerator-freezer, atmospheric pressure overcomes silica-gel sphere 2 gravity by silica-gel sphere
2 jack-up, now upper channel 11 connects with lower channel 12, and vent valve is opened, it is achieved the pressure release principle of ventilating valve apparatus, until refrigerator-freezer
When external and internal pressure is identical, door body can easily be opened.Realize pressure release owing to vent valve automatically opens up, and because of permeability cell the mouth of pipe relatively
Greatly, pressure release effect is obvious, and the time that freezer door is opened shortens several times.
These are only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality
Any amendment, equivalent and the improvement etc. made within novel spirit and principle, should be included in guarantor of the present utility model
Within the scope of protecting.
