[specific embodiment]
With reference to figure 2 and Fig. 3, the vacuum crisper of one embodiment of the present invention comprises that 1 comprises a lid 2 and a box body 3.Lid 2 can be processed by plastic material with box body 3, for example ABS; Also for example inorganic case hardened glass can be processed by other materials that can resist box body external and internal pressure difference.One end of lid 2 is provided with the vacuum-packed release gear 4 that discharges vacuum crisper 1; Other end setting is set up the vacuum-packed draw-out device 5 of vacuum crisper 1; Lid 2 links together through the bayonet unit that is separately positioned on its both sides with box body 3, follow-up will the detailed description in detail of structure of these devices 5,6,7.Central part at lid 2 also is provided with a depression 7; One grip 8 is pivotally connected on the lid 2 through hinge; Handle 8 can be housed under non-working condition in the depression 7, under running condition, turns to the position perpendicular to lid 2, and person easy to use carries vacuum crisper 1 on hand.
With reference to figure 4, an end of lid 2 has a depression 20, in depression 20, locating dowel pin 200 is set, and release gear 4 is housed in the depression 20.This release gear 4 comprises a charge valve, a support spring 44 and a fixed block 45.Charge valve comprises that 41, one of valve bodies can be inserted into the spool 42 in the valve body 41, and the cantilever 43 that can partly be inserted in the spool 42, and wherein the position of spool 42 is corresponding with the opening (not shown) of the filling channel of depression in 20.Support spring 44 is a bracing or strutting arrangement in the present invention, and it plays the function of switching device, and its position is arranged on the below of cantilever 43.Fixed block 45 is a registration device in the present invention, and its effect is that charge valve is positioned in the depression 20.Fixed block 45 is provided with the knock hole 450 that matches with the locating dowel pin 200 that caves in 20, and with cantilever 43 on manoeuvre portion 43 corresponding through holes 452.When charge valve be positioned piece 45 be fixed on the depression 20 in the time, support spring 44 is compressed and is against the below of cantilever 43, this moment manoeuvre portion 43 extend fixed block 45 by 452 of through holes.Because support spring 44 acts on the bearing force on the cantilever 43, the part that cantilever 43 is inserted in the spool 42 applies downward application force to spool, thereby makes the opening of spool 42 sealing filling channels.If will remove the vacuum seal of vacuum crisper 1; The operator applies downward pressure can for manoeuvre portion 430; Thereby the part that cantilever 43 is inserted in the spool 42 is upturned, and removes the sealing of the opening of 42 pairs of filling channels of spool, makes extraneous air enter into vacuum crisper 2.
With reference to figure 4 and Fig. 5, the other end of lid 2 has a depression 22, and locating dowel pin 220 and bleed-off passage 222 are set in depression 22, and draw-out device 5 is housed in the depression 22.This draw-out device 5 comprises 51, one extraction valves of a joint, and a fixed block 54.Its center tap 51 is the suction nozzles that can be used with other joints.Extraction valve comprises with bleed-off passage 222 corresponding valve bodies 52 and is inserted into the spool 53 in the valve body 52.Fixed block 54 is a registration device in the present invention, and its effect is that charge valve is positioned in the depression 22.Fixed block 54 is provided with the knock hole 540 that matches with 202 the locating dowel pin 220 of caving in.
With reference to figure 6, spool 53 is ducted bodies of being processed by the plastic material of softness, and it has hollow bulb 530 and deformable part 532.Bleed-off passage 222 raises up in depression 22, and it has centre gangway 224 and extraction opening 226, and wherein the section shape of extraction opening 226 is inverted tapered opening substantially.With reference to figure 7, after the evacuation of vacuum crisper finished, extraneous air was directed in the hollow bulb 530 of spool 53 automatically.About this automatically imported method, in the Chinese invention patent application of " vacuum fresh-keeping system and control method thereof " detailed description is arranged in another part denomination of invention of the applicant, repeat no more at this.At this moment; Owing to have air pressure difference towards a side of hollow bulb 530 and between a side of the centre gangway 224 of bleed-off passage 220 in deformable part 532; Thereby on deformable part 532, produce the pressure along direction A, this pressure makes deformable part 532 deform, thereby makes the deformable part 532 and the tapered opening of extraction opening 226 fit tightly each other together; Realization is to the sealing of bleed-off passage 222, and then realization is to the vacuum seal of vacuum crisper 1.In the present invention, the tapered opening of extraction opening 226 has increased the area of contact of deformable part 532 with extraction opening 226 greatly, is very beneficial for keeping for a long time the vacuum seal of vacuum crisper 1.
With reference to figure 4, bayonet unit 6 is arranged on the both sides of vacuum crisper again, and it comprises spanner 61 and hook part 62.Spanner 61 is pivotally connected on the side of box body 3 through hinge 64, and hook part 62 is pivotally connected on the spanner 61 through pin 63, and the end of hook part 62 can be detained on the side that is held in depression 7.During use, can make hook part 62 open vacuum seal box 1 from lid 2 disengagings thereby outwards pull spanner 61; Thereby pull spanner 61 and hook part 62 button is held on the side of depression 7 lid 2 and box body 3 are linked together to pressing down.
With reference to figure 8, vacuum crisper 1 of the present invention is set in the household electrical appliance, for example in the reefer of domestic refrigerator or refrigerator.For the ease of vacuum crisper 1 is controlled, on the inside face 90 of the casing 9 of reefer, control panel 92 is set, can be provided with on this control panel 92 vacuum crisper 1 release the button with vacuum crisper 1 abnormal work the time alarm button.Certainly, the position of control panel 92 also can be according to user's needs adjustment, and for example the control panel with household electrical appliance is arranged on the door of household electrical appliance.In view of the above, the food in the vacuum crisper 1 of reefer is in the storage condition of not only low temperature but also hypoxemia, low bacterium, can preserve the longer time.
The convenience of vacuum crisper of the present invention is: the gas filled device 4 on the vacuum crisper 1 can independently be controlled, and removes the vacuum seal of vacuum crisper 1 when the operator can independently be chosen in and need through operating portion 430; And the pressure that the air extractor on the vacuum crisper 15 utilizes the inside and outside air pressure difference of box body to produce is realized the automatic seal to vacuum box, need not to worry that the effect generation vibration displacement owing to external force makes the sealing of vacuum crisper loss of vacuum.
It is pointed out that above description only is one embodiment of the present invention, those of ordinary skill in the art is with reference on the basis of above embodiment, the reasonable adjustment of the present invention being made not paying creative work.For example; Be to realize switching function in this embodiment to gas filled device 4 through cantilever 43 and cooperating of support spring 44; Also can for example shell fragment or knob replace support spring 44 to serve as switching device with other elements; Again for example, gas filled device 4 all is arranged on the lid 2 with release gear 5 in this embodiment, also can be as required their position adjustment be fallen on the box body 3; As long as these adjustment can realize goal of the invention of the present invention, these reasonable adjustment all should be within the protection domain of claim of the present invention.
