The accompanying drawing explanation

Fig. 1 is a schematic diagram according to the apparatus for household use of invention;

Fig. 2 is the part of the apparatus for household use of Fig. 1, and it has a particular design for removable container; With

Fig. 3 is the view of Fig. 2, but container is removed.

The specific embodiment

The embodiment hereinafter described in detail is the preferred embodiment of the present invention.

Basic conception of the present invention is, stores in a vacuum food, and wherein, vacuum is used to produce a corresponding confining force simultaneously, and it is to keep reservoir vessel necessary.In preferably fresh food being stored in to container under vacuum, wherein, container is suspended in or is pressed on a suitable holding device in side.Can realize thus a kind of in kitchen the new mode of storage food, wherein, the memory space usually do not utilized is used fully.

The system of setting forth hereinafter can be that an independent apparatus for household use or one predetermined have a part that other determine the apparatus for household use of function.Therefore described system can for example be integrated into the apparatus for household use that also forms therewith a combination in a refrigerator.

In addition, described system also can be arranged in kitchen with independent module.Therefore it can for example be fixed on below a hanging cupboard or the direct bottom as hanging cupboard.

There is a vacuum keeping system according to the apparatus for household use of invention, utilize it to lay the container that food is housed with hang.This device of operation that thus can be particularly singlehanded because each container only needs to remain on the surface of this keeping system, produces vacuum on this surface.By the vacuum keeping system also possible that, can operate contiguously this device without sight line in addition.This be because, the operation that do not need other by taking out on a surface that air in container can be drawn onto suitable container on a definite surface.Such vacuum keeping system can be installed very flexibly in addition.Wherein particularly can use almost arbitrary shape and the kitchen vessel of compactedness arbitrarily.Only need to guarantee, the surface of holding device or keeping system can be to aeroseal ground sealing kitchen utensil or container.

Now by Fig. 1, describe a concrete apparatus for household use, it has above-mentioned vacuum keeping system.Shown in solution in specially refer to a kind of vacuum suspension.By air driven pump 1, air is extracted out from vacuum tank 2.Also can be with any one other the pump that can produce desired vacuum replace air driven pump 1.

Air passes through pipeline 3 by pump 1 sucking-off from vacuum tank 2.A pressure regulator valve 4 is arranged in pipeline 3.This pressure regulator valve is surveyed the pressure in vacuum tank 2 and is offered 1 one corresponding sensor signals of pump.By a circuit 5, pressure regulator valve 4 is connected with pump 1 for this reason.Therefore form a control loop, utilize its pressure in can fine adjustment vacuum tank 2.

Also can be in vacuum tank 2 or pipeline 3 or on pressure sensor is set to replace pressure regulator valve 4, this sensor provides a corresponding pressure signal for pump 1.The valve function of pressure regulator valve 4 also can self be realized by pump 1 in this case.

Can design if necessary higher level's control device, for presetting the pressure nominal value for vacuum tank 2.Vacuum in vacuum tank 2 just is controlled in a given range of this rated value.

Apparatus for household use has a holding device 6, it its this, for example have one horizontally disposed be flat or tabular bearing 7 basically.This tabular bearing 7 can be for example the base plate of a hanging cupboard or can be also the dividing plate of a cabinet.This outer support 7 can be also inwall or the inner bottom plating of a refrigerator.This outer support 7 can be also any one outer wall of a cabinet or a kitchen apparatus.If bearing 7 is vertical, container 8 that can containing foodstuff is not just in time to be fixed on hangingly on bearing 7, but at lateral surface compressing on this bearing.Food in container 8 to be stored in is not expressed in Fig. 1.Container 8 is only usingd section at this and is illustrated as the container of peviform.They respectively have an opening 9, by this opening, food can be put in container 8.

At the downside of bearing 7 or on outside it, resilient mat 10 or a flexible coating are arranged.Resilient mat 10 or resilient coating are had larger flexible material than bearing 7 and are made by a kind of.To resilient mat 10 alternatively or additionally, can make the opening 9 of container 8 there is a resilient edge.In this case this elastic edge by a kind of elasticity of container 8 larger material make.The elastomeric material of flexible mat 10 or this container edge can be for example silicone.Also can choice for use other the elastic artificial material who is suitable for processed food or natural product.

The material of container 8 only is limited under vacuum can not produce very large distortion.But this deformation performance also is subject to the thick impact of wall of a container.Suitable material is for example: glass, plastics, metal etc.Glass and transparent plastics have extra benefit, can see well from outside the food be stored in container.Optically there is certain thickness material to have the following advantages comparatively speaking, i.e. stored food can not suffer damage due to illumination (decomposition of Vitamin C).

Mat 10 at the example Elastic of Fig. 1 has projection 11, and it is outstanding downwards from the downside of mat 10.A pumping part 12 is arranged in the centre of each projection 11.In the simplest situation, this pumping part 12 is small tubes.Each pumping part 12 is connected with vacuum tank 2 by an air intake duct 13 separately.Each pumping part 12 places that thus can be on the downside of bearing 7 or flexible mat 10 are by air intake vacuum tank 2.

The advantage of projection 11 is to operate contiguously this apparatus for household use or this vacuum keeping system without sight line.Definite saying because projection 11 can be easy to touch and feel found air-breathing position when the mobile containers 8.Alternatively, mat 10 also can for example be provided with outstanding elasticity hemisphere downwards, in its lower end, arranges each pumping part.It is to be noted, the surface of bearing 7 or flexible mat 10 is not necessarily flat, and can have different surface textures simultaneously.

Food container 8 is by atmospheric pressure p ₀and the pressure differential between the vacuum in container 8 remains on flexible mat 10 from below.This pressure differential is pressed into each container 8 in flexible mat 10 by its edge.Flexible mat 10 is therefore to the outside closed container 8 in aeroseal ground.Prerequisite is that flexible mat 10 or elastic coating and bearing 7 are consistent on geometry with the opening 9 of container.For example by the edge of this opening, determined a plane, and flexible mat 10 is also flat.By this geometry, can realize air impervious sealing.Air impervious like this sealing also can realize by the spherical structure in mat 10 or a zone this mat.Under any circumstance the geometry of mat surface is consistent with the geometry of container 8.

Vacuum in each container can be controlled by each sensor 14.Such sensor 14 typically is close to projection 11 or pumping part 12 is arranged.The existence of sensor 14 exploration vessels 8 by valve 15 of a corresponding sensor signal switch, this valve is disposed in described or each air intake duct 13.When removing container, valve 15 cuts out.When the container 8 in there is recorded by sensor 14 separately on affiliated pumping part 12, open similarly valve 15 separately.

Sensor 14 can be according to different Fundamentals of Sensors work.Can for example design infrared ray sensor or ultrasonic sensor, thereby container is surveyed.Also Sensor Design can be become to button so principle based on a machinery.The mechanically existence of exploration vessel thus.This outer sensor can be also a pressure gauge, utilizes it can learn the variation of pressure.When the pressure decreased at air-breathing position or pumping part 12 places, set out thus to derive has a container 8 on air-breathing position.Otherwise pressure can significantly not reduce.

To further set forth now according to Fig. 2 and 3, and how food container 8 can be taken off from the vacuum keeping system.In Fig. 2, container 8 is in sucking state, in the vacuum of internal tank, overcomes gravity g and it is pressed on flexible mat 10.Bearing 7 is comprised of a support plate 16 with square-section at this.Added a resilient section 17 in this square-section, it is connected with the support plate 16 flush ground of rigidity.Edge 18 has defined the support plate 16 of rigidity on the surface of bearing 7 and the boundary between elastic segments 17.Along this edge 18, the downside perpendicular to bearing 7 extends a wall, and this wall part ground forms by support plate 16 and partly forms by flexible section 17.At edge, a side of 18 is harder material (rigid mount plate 16), and at opposite side, is the elastomeric material of section 17.This elastomeric material can be for example foamed material.Support plate 16 preferably is comprised of plank or plastic plate.

Because edge 18 is positioned at projection 11 and is positioned at thus pumping part 12(, at Fig. 2 and 3, do not express) the next-door neighbour around, under the storage configuration up to specification (sucking state) of container 8, the part of this container is located immediately at the hard material below of support plate 16, and a part is positioned at flexible section 17 belows.

Due to the elasticity of the material of section 17, container 8 is overturn to the right in order to dismantle according to Fig. 3, as by as shown in arrow 19.Container 8 is pressed in the elastomeric material of section 17 easily thus.Therefore this container is turned to 18 tops, edge of rigid mount plate 16.Formed thus an air duct 20, it has reduced confining force, makes effortless being removed of container 8 energy.

Therefore above-mentioned vacuum keeping system provides a kind of possibility, that is, vacuum is both for improving the shelf-life of food, simultaneously also for fixed container.Particularly use thus individual container to become possibility.By above-mentioned control and governor motion, the user, do not need device is carried out to any hand switch on the one hand in addition.

Deposit because food container can be draped, therefore do not need placement surface, this placement surface can be used as working face or other purposes.This outer container can be loaded onto at an easy rate and take off.In set forth system, when loading onto and take off container, operated intuitively.

Because this system does not rely on the configuration of container basically, so for example also can use air-tight bottle, the Cans of opening or glass drink device as container.Native system arbitrary arrangement almost in addition, in order to hold the container of corresponding desired amt.

Utilize the native system can open-and-shut storage food and be easy to take food.First test shows in addition, and the shelf-life of fresh food is significantly improved.
