The specific embodiment

Describe embodiments of the invention below in detail, the example of said embodiment is shown in the drawings, and wherein identical from start to finish or similar label is represented identical or similar elements or the element with identical or similar functions.Be exemplary through the embodiment that is described with reference to the drawings below, only be used to explain the present invention, and can not be interpreted as limitation of the present invention.

In description of the invention; Term " interior ", " outward ", " on ", the orientation of indication such as D score or position relation be for based on orientation shown in the drawings or position relation; Only be for the ease of describing the present invention rather than requiring the present invention therefore can not be interpreted as limitation of the present invention with specific azimuth configuration and operation.

Following with reference to a kind of refrigerator of figure 1-Fig. 7 description according to the embodiment of the invention.

As shown in Figure 1, according to the refrigerator of the embodiment of the invention, comprise casing 1, chamber door 2 and vacuum extractor 3.Wherein, casing 1 front side is opened wide, and chamber door 2 is used to open and close the front side of casing 1.

Vacuum extractor 3 is installed in the chamber door 2, and comprises vavuum pump 31 and coupled pumping mouth 32.Pumping mouth 32 extends from the front side of chamber door 2 and exposes chamber door, be used for outside vacuum equipment for example the suction nozzle of vacuum box or vacuum bag cooperate, so that vacuum equipment is vacuumized.The control mode of vacuum extractor 3 has changed the control mode that presses down pumping mouth of conventional refrigerator vacuum extractor for drawing the mode of pumping mouth outward.

Like Fig. 2, Fig. 3 and shown in Figure 5, in one embodiment of the invention, vacuum extractor 3 further comprises fixed head 33.Fixed head 33 is installed in the chamber door 2, and vavuum pump 31 and pumping mouth 32 and other annexes for example tube connector etc. are installed on the fixed head 33, and like this, fixed head 33 becomes an independently installing plate assembly with vavuum pump 31 with pumping mouth and other enclosure group, is convenient to installation and removal.

Shown in Fig. 4-7, in another embodiment of the present invention, vacuum extractor 3 also further comprises embedded box 34.Embedded box 34 is embedded in the chamber door 2; Fixed head 33 is fixed in the embedded box 34; And vavuum pump 31 and pumping mouth 32 and other annexes are installed in the front side of fixed head 33, and the installing plate assembly is inserted into the embedded box 34 and fixing from the rear side of chamber door 2, makes pumping mouth 32 to extend towards the front side of chamber door 2.Alternatively, when chamber door 2 is installed with embedded box 34 predetermined fixed on the door shell body of chamber door 2, foaming together then is embedded in embedded box 34 in the foaming layer in the chamber door 2, saves the space.In an example of the present invention, on embedded box 34, be provided with threading hole 51, the lead that this threading hole 61 is used to supply to connect vavuum pump 31 and external control circuit passes through.Alternatively, this threading hole 51 is positioned at the below of embedded box 34.

Thus, the installing plate assembly is installed in the embedded box 34, and connects external control circuit through the lead that passes threading hole 51, and connects the switch of different gears so that the time that control vacuumizes.

In another embodiment of the present invention, like Fig. 2-shown in Figure 5, vacuum extractor 3 also further comprises panel 35.Wherein, the position corresponding to embedded box 34 on chamber door 2 is provided with opening 21, panel 35 these openings 21 of sealing.On panel 35, be provided with pumping mouth outlet 61, pumping mouth outlet 61 is corresponding with the position of pumping mouth 32, and pumping mouth 32 passes pumping mouth and exports 61 and extend from chamber door 2 front sides and be exposed to the chamber door outside.Like this, make the process that vacuumizes can accomplish in the outside of chamber door 2, simple and easy to do.

In some of them example of the present invention, between fixed head 33, vavuum pump 31 and embedded box 34, adopt the mounting means of sealed, thermally insulated processing, as shown in Figure 4.

Briefly introduce the course of work of refrigerator according to the present invention when vacuumizing below with reference to Fig. 1-Fig. 7.

Like Fig. 1 and shown in Figure 5, for example suction nozzle and the pumping mouth 32 of vacuum box or vacuum bag fit and compress and get final product with the vacuum equipment of outside when vacuumizing.And vacuumize to need only when finishing vacuum box or vacuum bag are removed from pumping mouth 32, vavuum pump 31 can quit work.

Further, refrigerator according to the present invention has been simplified the process that vacuumizes, and has reduced the used parts of pumped vacuum systems, and the probability that therefore breaks down reduces greatly, has improved reliability, and has reduced the maintenance cost in later stage.
