The specific embodiment
As shown in Figure 2, the vacuum sealing system of embodiments of the present invention comprises box body 20, and wherein, an end of box body 20 is provided with air-breather 21, and the other end is provided with aspirator 22.Air-breather 21 and aspirator 22 can be check-valves.
Vacuum sealing system also has control device.This control device comprises circuit board 28 and control panel 32.Circuit board 28 is connected to switching device 25, vacuum extractor 26, vacuum measuring device 29 and control panel 32, and receives feedback signal from these devices, and sends corresponding order.Starting button 32 and alarm button 34 are attached to control panel 32.The effect of starting button 32 is starting vacuum extractors.The effect of alarm button 34 is output alarm signals when vacuum sealing system is in the abnormal operation state.In another Chinese patent application " refrigerator and control method (Elektrischer K ü hlschrank mit Vakuumfrischhaltesystemnebst Steuerungsverfahren) thereof " that proposes by applicant of the present invention with vacuum fresh-keeping system, describe the warning function of vacuum sealing system in detail, therefore saved the description that repeats.
As shown in Figure 3, the step of the control method of vacuum sealing system of the present invention is as follows: the user is the starting button on the actuation control panel 32 32 and start the process that vacuumizes at first.Control panel 28 is judged the position of switching device 25.If switching device 25 is shown in an open position, control panel 28 is given an order switching device is switched to the closed position.At last, control panel 28 is given an order and is started vacuum extractor 26, and described vacuum extractor 26 beginnings vacuumize by means of 24 pairs of box bodys 20 of suction tube.Simultaneously, vacuum measuring device 29 is measured the vacuum level in the suction tube 24 continuously and show measured value on control panel 28.If the vacuum level in the suction tube 24 does not reach the regulated value of previous setting, control panel 28 is given an order, and keeps the operation of vacuum extractor 26 whereby.After certain hour, when the vacuum level in the suction tube 24 had reached the regulated value of previous setting, control panel 28 sent the order of the operation that stops vacuum extractor 26.At last, after the operation that stops vacuum extractor 26, control panel 28 is given an order, and this order switches to open position with switching device 25 from the closed position, and extraneous air is imported suction tube 24 with certain flow velocity.Thereby, finish the process that vacuumizes.
As shown in Figure 4, box body 20 comprises base portion 204 and cover cap 202, and base portion 204 is sealed by means of cover cap 202.Air-breather 21 and aspirator 22 are attached to the two ends of cover cap 202 respectively.Jockey 23 on the cover cap 202 is connected to aspirator 22.In the present invention, after switching device 25 was switched to open position, extraneous air flowed into suction tube 24 and arrives aspirator 22 through connector 23.Because box body 20 is evacuated, therefore, between box body 20 inside and outside, have pressure differential, like this, external air pressure produces extruding on aspirator 22, and realization is to the vacuum seal of box body 20.At design aspect, this aspirator 22 is check-valves.At another Chinese patent application that proposes by applicant of the present invention " vacuum crisper and use household electrical appliance (the Vakuumfrischhaltedose und diese Vakuumfrischhaltedose verwendendeelektrische of this vacuum crisper
) " in describe the particular design of aspirator 22 in detail, thereby, save further description at this.Because the vacuum seal point of box body 20 is in the position of aspirator 22 on cover cap 202, therefore, to reveal or get loose even exist at the some place of jockey 23, air also only can reach connector 23 and suction tube 24, and does not reach box body 20.The vacuum seal of box body 20 can not be subjected to the harmful effect of the leakage of appearance on connector 23 and the suction tube 24.
Vacuum sealing system of the present invention can use individually, but also can be installed in the household electrical appliance also as annex.Especially, it can be attached on household electric refrigerator or the freezer unit.In this case, box body 20 can be used in the stored under refrigeration compartment of refrigerator.But suction tube 24 sinks are in the froth bed of the compartment of refrigerator.The connector 23 that links to each other with suction tube 24 can be attached on the inwall of stored under refrigeration compartment.The door that control panel 32 can be attached to refrigerator go up or the inwall of stored under refrigeration compartment on so that can be by user's simple operations.
Must be pointed out that the description of front only relates to one embodiment of the present invention.Those of ordinary skill in the art can adjust the present invention on the basis of considering aforesaid embodiment suitably, and does not need creationary work.For example, the switching device 25 of the embodiment among Fig. 2 of this aspect is a check-valves.Yet, also can adopt another traditional switching device to come to import extraneous air, at closed position sealing suction tube 24, as long as can realize this function at open position.And aspect the position of vacuum measuring device 29, it can for example be attached to suction tube 24 or also can be attached to box body 20, as long as can realize measuring in real time the function of variation of the vacuum level of vacuum system.These suitable adjustment still belong in the protection domain of claim of the present invention.
