Specific implementation mode
To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below
In conjunction with specific implementation mode, the utility model is expanded on further.
Referring to Fig. 1, the utility model provides a kind of technical solution：A kind of refrigerator automatic pressure-reducing device, including it is automatic
Decompressor shell 1 and automatic pressure-reducing device chamber body 2 form, and the automatic pressure-reducing device shell 1 includes box cover 11 and box body 12；
The box cover 11 includes lid 111 and link 112；The box body 12 includes admission line 121, box body inner cover 122 and the box body back of the body
Plate 123 forms；The automatic pressure-reducing device chamber body 2 is 21 structure of movable closing door；1 box cover 11 of the automatic pressure-reducing device shell
It is connect by manner with box body 12；The automatic pressure-reducing device is inserted in groove built in refrigerator box body by box cover 11
Link 112 is by bolt lock on refrigerator box body, and automatic pressure-reducing device chamber body 2 is in automatic pressure-reducing device shell 1, this practicality
New device construction is simpler, and cost is relatively low, reasonable for structure, and service life is long, easy to operate, by automatic pressure-reducing device to cold
Cabinet external and internal pressure is adjusted, and refrigerator external and internal pressure is allowed to reach balance, ensures that next time opens the door and is easy and reduces door body fluid sealant
Item, which is damaged and reduced in chamber body, coagulates the frost reduction cleaning solidifying white time.
Specific implementation mode：In progress in use, staff first checks the utility model, checks whether and deposit
In defect, it can not just carry out using if there is defect, need that maintenance personal is notified to repair at this time, if do not deposited
It can be carried out using if problem；The inside and outside pressure of refrigerator is in equilibrium state when normal state refrigerator normal operation
Internal cold air is moved by case, as see arrows 17 in fig 3 direction, but because the refrigerator of admission line 121 is in closing
State, so cannot flow out to outside refrigerator box body；Freezer door body open state, it is cold because entering many hot-airs when enabling
In-cabinet temperature is basic as ambient temperature.Pressure is also in parallel state with the external world；Door body closed state, in refrigerator there are
Hot-air by refrigeration system because being influenced temperature dramatic decrease, and therefore, air can be compressed in refrigerator.It is extraneous after air compression
Air direction as shown in Fig. 4 arrows flows into.At this moment, because of pressure difference relationship, the refrigerator of admission line 121 is in open state,
In this way, extraneous air can be flowed by the refrigerator of admission line 121 in refrigerator, until pressure is in equilibrium state.By with
Upper action, refrigerator internal pressure can form equilibrium state with extraneous, and therefore, enabling is easier, and reduces door body sealing joint strip damage
Frost reduction cleaning is coagulated in bad and reduction chamber body coagulates the white time.
