Based on the setting of refrigerator inside and outside air pressure balance component 100, before the unlatching of refrigerator door 21, by being connected to inner container of icebox
It can be to avoid pressure difference be generated inside and outside refrigerator, so that user be facilitated to open refrigerator door 21 with the external world.
More specifically, refering to what is shown in Fig. 3, refrigerator also has the probe unit 23 for detection user location and is connected to
The control unit (not shown) of probe unit 23, specifically in the present embodiment, before probe unit 23 is set to door body 21
Side, probe unit 23, which can be infrared detection head or camera etc., can detect the mobile element of user.
In the specific application process, when probe unit 23 detects user close to refrigerator, control unit can be according to spy
The signal control electromagnet 14 of survey is powered to open valve 13.It can so be opened inside and outside forward horizontal stand refrigerator in refrigerator door 21
Air pressure.
In general, valve 13 involved in the present invention needs to re-close after unlatching, it specifically can be in the following manner
To realize: mode one, by the energization period of control unit pre-given electromagnetic iron 14, after electromagnet 14 opens a period of time
Power themselves down, to realize re-closing for valve 13；Mode two: the sensor that setting induction door body 21 is closed on refrigerator,
When sensor sensing is to user's closing refrigerator door body 21, i.e., by the control unit control power-off of electromagnet 14 to realize valve 13
It re-closes；Mode three incudes whether user leaves refrigerator by probe unit 23, when sensing that user leaves refrigerator, i.e., logical
The control unit control power-off of electromagnet 14 is crossed to realize re-closing for valve 13.
Refrigerator inside and outside air pressure balance component 100 involved in the present invention will respectively be preferably implemented structure below to make further
It is described in detail.
With reference to shown in Fig. 1, Fig. 2, in the present embodiment, tracheae 12, which has, is connected to extraneous external port 121, and valve 13 is set
It is placed at 121 position of external port with closure or openness external port 121.
Specifically, the external port 121 in the present embodiment is obliquely installed upwards, and balanced component 100, which has, is set to external port
The shaft 130 overturn at 121 upper edge positions for valve 13.Refering to what is shown in Fig. 1, valve 13 exists when electromagnet 14 powers off
External port 121 is closed under self gravity, to avoid the convection current of refrigerator inner air and outer air；Refering to what is shown in Fig. 2, when electromagnet 14 is logical
When electric, the magnetic force that electromagnet 14 is applied to valve 13 overcomes 13 gravity of valve so that valve 13 130 is flipped open around the shaft, thus
It realizes and is connected to the external world via tracheae 12 inside inner container of icebox, and then achieve the purpose that balance refrigerator inner and outer air pressure.
In another unshowned embodiment of the present invention, balanced component 100, which has, drives valve 13 to be closed to external port 121
Elastic component, i.e. valve 13 closed in external port 121 by means of the elastic force of elastic component, when electromagnet 14 is powered, electromagnet
14 magnetic force for being applied to valve 13 can overcome the elastic component to the elastic force of valve 13, to realize the unlatching of valve 13.
Certainly, as a kind of optimal embodiment of the invention, in the illustrated embodiment, valve 13 also connects flexible
Part (not shown), the elastic component can preferably be such that valve 13 is sealed in external port 121, when electromagnet 14 being avoided to power off
Valve 13 generates unnecessary shaking.
In the present embodiment, balanced component 100 also has with inner container of icebox connection inner container of icebox interior liquid is discharged
The drainpipe 10 of water, the tracheae 12 in the present invention also have inner port 122 for being connected to inside inner container of icebox.Specifically,
Inner port 122 is connected to the side wall of drainpipe 10 and is connected to being formed inside drainpipe 10.Tracheae 12 i.e. in the present embodiment is
