Abstract

A vacuum preserving cabinet comprises a vacuum pump, a storage chamber, an inlet valve, an exhaust valve, a handle, etc, wherein, the preserving cabinet adopts the storage chamber structure of multiple-layer independent sealing, a one-way exhaust valve and the vacuum pump for pumping vacuum and a pressure relay are all arranged in the cabinet, the utility model has the advantages of large storage quantity, small consumption, low cost, etc. The utility model is not only applicable to the preservation of food, but also applicable to the long time storage of books, cultural relics and archives. The utility model has nice and simple appearance and auto control of the inside vacuum, hence a vacuum preserving cabinet of new generation and wide use.

Description

The vacuum freshness retaining storage cabinet

The utility model relates to a kind of storage apparatus, relates in particular to a kind of vacuum storage cabinet.

Existing food, the preservation of article and fresh-keeping refrigerator and the refrigerator-freezer that adopts low-temperature storage more, volume is few, and storage is little, and energy consumption is big, the unit cost height, and moist in the casing, the holding time should not be too of a specified duration.Books, archives and historical relic class article phase preserve, and need constant temperature especially, constant humidity, and equipment investment is big, and retain costs is higher.Though at present on the market a kind of vacuum fresh-keeping cabinet is arranged also, it is fresh-keeping to be mainly used in foodstuff, belongs to single cabinet, and volume is few, and need manual starting vavuum pump, of non-ideal use, vavuum pump and air bleeding valve are placed on outside the casing, associative perception is poor, and external form is not attractive in appearance, as patent 97208306.8.

The purpose of this utility model is to provide a kind of the fresh-keeping of food that not only be applicable at the above deficiency of prior art, also is applicable to the permanent preservation of books, archives and historical relic article simultaneously, and internal memory is bulky, the fresh-keeping storage cabinet of multi-layer vacuum.

The purpose of this utility model is realized by following scheme:

This storage cabinet is made up of vavuum pump, apotheca, intake valve and air bleeding valve and handle etc., storage cabinet adopts the apotheca structure of the separate sealing of multilayer, all install to vacuumize within each apotheca and use one-way exhaust valve, and be connected in the vavuum pump that is installed in the bottom apotheca after with tube connector and adapter assembly each air bleeding valve being connected.

The utility model is compared with prior art, owing to adopted multilayer bookshelf-type structure, storage capacity is big, the saving energy, and cost is low, and not only be fit to food fresh keeping and deposit, and the long-term storage of suitable books, historical relic and archives; Because vavuum pump and air bleeding valve all are loaded in the storage cabinet, handsome in appearance, succinct, integral body is felt all right, and internal vacuum can control automatically, is a kind of a new generation, broad-spectrum vacuum freshness retaining cabinet.

Fig. 2 is the utility model front view;

Fig. 3 is the utility model air bleeding valve and adapter assembly cut-away view;

Fig. 4 is the utility model intake valve schematic diagram;

Fig. 5 is the utility model circuit diagram.

Below in conjunction with accompanying drawing example is described in detail.

As Fig. 1, shown in Figure 2, the utility model comprises vavuum pump 27, apotheca 28, intake valve 5 and air bleeding valve 3 and shake hands 2 etc., every layer of apotheca 28 separate sealing, all install in it and vacuumize with one-way exhaust valve 3, as shown in Figure 3, its center tap 14 passes box partition 13 back and compresses rubber sheet gasket 22 with clamp nut 11 and seal,

collar nut

19,25,

rubber sheet gasket

18,24 with on the three-way pipe 23, following outlet is tightly connected with tube connector 17, the central exit inwall of three-way pipe 23 is with spring 20, withstand the rubber spool, block the end face through hole of nut 22, nut 22 is threaded onto on the outer wall thread of three-way pipe central exit, thus the air bleeding valve 3 in the composition diagram 1.After connecting the air bleeding valve in each layer apotheca 28 3, tube connector 17 and adapter assembly be connected in the vavuum pump 27 in the apotheca that is installed in the bottom.As shown in Figure 4, handle 2 is loaded on the upper right side of glass door 1, a connecting rod 7 is fixed with pin 6 in its top, connecting rod 7 left parts are adorned a fixed cover 8, put rubber valve plate 9 in it, the elastic force that is fixed in the spring leaf 10 on the connecting rod 7 tightly is pressed on the through hole of glass 1 rubber valve plate 9, thus the intake valve 5 in the composition diagram 1.Pressure switch 29 is installed on the vavuum pump 27, inserts power supply after the motor in series in the contact of pressure switch 29 and the vavuum pump 27, as shown in Figure 5.

During work, vavuum pump 27 runnings, tube connector 17 and each rubber spool are under the effect of negative pressure, form vacuum in the adapter assembly, pull of vacuum overcomes the resistance of spring 20, drives the end face through hole that rubber valve plate 22 is opened nut 20, and the air in the apotheca 28 enters three-way pipe 23 and tube connector 17 is drawn in the vavuum pump 27 through the dentation recess of the central exit end face of three-way pipe 23 from this through hole.When the air in each apotheca was pumped to certain negative pressure, vavuum pump 27 quit work under the effect of pressure switch 29.

In the time of need getting a certain stored goods, with the connecting rod 7 on the finger pull handle 2, connecting rod 7 overcomes the elastic force of spring leaf 10, rubber valve plate 9 is opened, and air enters apotheca 28 through the through hole of glass door 1, treat that indoor vacuum reduces after, can open glass door 1, take out article, pressure switch 29 is connected circuit at this moment, and vavuum pump 27 is started working.Because the vacuum in the tube connector 17 is not got vacuum in the apotheca of article less than other, each air bleeding valve 3 in it is closed, thereby has realized the separate operation of each apotheca, non-interfering purpose.
