Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further illustrated。Wherein the accompanying drawing in accompanying drawing 1-6 is labeled as: 1, drawer, 2 drawer upper covers, and 311, upper latch notch, 312, lower bayonet socket, 61, upper buckle, 62, lower buckle, 4, hole, 51, interface；321, top edge, 322, lower limb；33, self sealss bar, 34, opening, 42, relief valve, 52, vacuum valve joint；34, vacuum bag coordinates mouth；7, vacuum pump, 8, vacuum tube。
For solving the Problems existing of prior art, this utility model provides a kind of vacuum freshness retaining refrigerator, and this refrigerator adopts vacuum bag to seal。This vacuum freshness retaining refrigerator has pumped vacuum systems, drawer 1, vacuum bag, control device；Wherein pumped vacuum systems has vacuum pump 7, vacuum valve and vacuum line 8；Drawer 1 has the interface 51 being connected with the vacuum valve joint 52 on vacuum valve and vacuum bag；Vacuum bag has opening, relief valve 42 and vacuum valve joint 52；The vacuum valve joint 52 of vacuum bag coordinates with the interface 51 on drawer, and vacuum valve joint 52 can be affixed on the interface 51 of drawer 1, it is also possible to takes off from the interface 51 of drawer 1；During use, the vacuum valve joint 52 of vacuum bag is affixed on the interface 51 of drawer 1, and when drawer 1 is pulled to behind the position in refrigerator, the interface 51 on the vacuum valve joint 52 of vacuum bag, drawer 1 is connected with the vacuum valve of pumped vacuum systems；Vacuum valve is attached to valve on vacuum line 8, bag vacuum is connected with vacuum pump 7 by vacuum valve and realizes。
Preferred vacuum valve is positioned at rear wall, and the vacuum valve joint 52 of described vacuum bag is positioned at vacuum bag rear portion, and described interface 51 is positioned at the rear portion of drawer 1, and described vacuum valve is positioned at rear wall；When drawer 1 is pulled to the position in refrigerator, the vacuum valve joint 52 at vacuum bag rear portion, drawer 1 rear portion interface 51 be connected with the vacuum valve being positioned at rear wall。
Another kind of scheme is that vacuum valve is positioned at refrigerator sidewall, and the vacuum valve joint 52 of described vacuum bag is positioned at vacuum bag side, and described interface 51 is positioned at the side of drawer 1, and described vacuum valve is positioned at refrigerator sidewall；When drawer 1 is pulled to the position in refrigerator, the vacuum valve joint 52 of vacuum bag side, drawer 1 side interface 51 be connected with the vacuum valve being positioned at refrigerator sidewall。
In detection vacuum bag, the pressure transducer of pressure also passes through to stretch into the pressure detecting in vacuum bag vacuum bag from the interface 51 of the vacuum valve joint 52 of vacuum bag, drawer 1。
The sealing of vacuum bag has three kinds of schemes: the first, the front opening of vacuum bag is combined with drawer 1 front opening, by the sealing strip on drawer 1, vacuum bag is sealed: the drawer 1 shown in vacuum bag as shown in Figure 4 and Fig. 2, the surrounding coordinating mouth 34 of vacuum bag is combined with the top edge 321 of the upper cover 2 of drawer 1 and the lower limb 322 of drawer 1, utilizes top edge 321, closing of lower limb 322 to be sealed by the opening 34 of vacuum bag。
The second, drawer 1 front portion has hold down gag, drawer 1 as indicated with 1, and vacuum bag front portion is compressed and seals by the upper latch notch 311 of drawer 1 front portion, lower bayonet socket 312。Upper buckle 61, lower buckle 62 in Fig. 1 can add strong pressure and location for hold down gag。
The third, vacuum bag opening itself has sealing device。Vacuum bag as shown in Figure 3 is with self sealss bar。Three kinds of modes are respectively arranged with advantage, repeat no more here。
Vacuum bag has relief valve 42。Relief valve 42 can expose from the hole 4 of drawer 1 front portion, is easy to open relief valve 42, after relief valve 42 is opened, and the air pressure balance inside and outside vacuum bag, then open vacuum bag and be easy for。
Vacuum freshness retaining refrigerator of the present utility model has triggering device, the startup triggering device makes vacuum pump 7 start, may be arranged such that the first, after drawer 1 is pulled to the correct position in refrigerator, triggering device starts: the second, after drawer 1 is pulled to the correct position in refrigerator, when refrigerator doors is closed, trigger device and start；The third, drawer 1 is pulled to the correct position in refrigerator, actuation button, triggers device and starts。These three mode is respectively arranged with advantage, repeats no more here。
Vacuum pump 7 starts, and whether the pressure that the pressure detecting numerical value recorded by pressure transducer is used to judge in vacuum bag is in default scope, until in pressure reach, vacuum pump stops。Pressure is not in preset range, and vacuum pump works。
Whether the force value in vacuum bag is effective in order to the sealing judging vacuum bag。According to the change within the unit interval of the force value in vacuum bag, whether vacuum pump works judges whether vacuum bag seals effective。Whether effectively all show on the display floater of refrigerator, especially invalid when sealing, namely should point out during gas leakage。Have and judge the whether effective judgment means of vacuum bag sealing and the whether effective device of prompting vacuum bag sealing。
Exhausting after the vacuum bag of vacuum places a period of time, somewhat leak because of air and vacuum reduces, the force value of pressure detecting is not in preset range, then vacuum pump starts until pressure reaches after in preset range, and vacuum pump stops。
Vacuum freshness retaining refrigerator of the present utility model, adopts vacuum bag as Dewar vessel, and vacuum bag is combined with drawer and makes evacuation and keep vacuum all to become easy；The material of vacuum bag is flexible, it is easy to evacuation also easily keeps sealing；Load after food can previously extruded exclusive segment air, the gas that therefore evacuation extracts is less, energy-conservation；Food in vacuum bag and vacuum bag are close to, and conduction heat exchange is also carried out；Vacuum bag is hardly damaged at low temperatures, even if damaging, it is also easy to change, and the cost simultaneously changed is little。So vacuum freshness retaining refrigerator of the present utility model overcomes the defect of prior art, food fresh keeping can be realized better。
