Abstract

The utility model provides a micro-energy-consumption oxygen isolation box for food preservation at ambient temperature, comprising a box and a box cover. The utility model is characterized in that the bottom of the box is provided with a plurality of orifices; the central orifice is provided with a valve which can vertically move; a water pipe which is welded with the bottom of the box is arranged outside the valve; one end of the water pipe is connected with a water pump; the top surface of the box is provided with an opening hole. The box is filled up with water; then the water is pumped out, a vacuum water vapor space with low vacuum degree is formed; the oxygen-insulating preservation is realized. The utility model has the advantages that the bacteria and mildew can be inhibited; the oxidation can be prevented; the self breath and dewatering of plants can be prevented; the structure is simple; the energy can be saved.

Description

Micro-energy-consumption oxygen isolation box for food freshness at ambient temp.

The utility model relates to food freshness-keeping box.

Usually food fresh keeping adopts refrigerator, makes temperature decline in the refrigerator by freon refrigeration, utilizes low temperature to contain bacterial reproduction, thereby reaches fresh-keeping.But the employing fridge freshness retaining will expend a large amount of electric energy, and refrigerator costs an arm and a leg.

The purpose of this utility model provides a kind of little energy consumption room temperature oxygen barrier food freshness-keeping box, and it can be fresh-keeping effectively, can save energy again.

The utility model is achieved in that it is made up of case, lid.Several apertures are arranged at the bottom of the case, a valve that can move up and down are housed in a central aperture, valve have outward one with water pipe fixing at the bottom of the case.

The utility model, is taken out water filling water in the case then according to the oxygen barrier fresh keeping principle, forms a low vacuum water vapour evacuated space.At room temperature oxygen barrier is contained the breeding of bacterium, small worm, mould etc., and anti-oxidation, stops plant individual self to be breathed and dehydration, reaches fresh-keeping.

The utility model is because the oxygen barrier space is the saturated vapor space, and food can not dewater, and room temperature in addition is so food has more original flavor than freezing and refrigeration.Simultaneously simple in structure, cost is low, cheapness, and have advantage than current refrigerator energy-conservation 99%.

Below with reference to drawings and Examples, the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

Among the figure, case 1 is used for foodstuff storing, and lid 2 and seal ring 4 are used for covering tight case hole 3.Open hole 7 covers 5 and seal ring 6 on it.Several apertures 8 are arranged at the bottom of the case, in aperture of central authorities a valve that can move up and down 12 and seal ring 13 are housed.Valve have outward one with the water pipe 11 that welds mutually at the bottom of the case, an end of water pump 10 links to each other with water pipe, the other end is provided with one and stops up 9.

When antistaling box uses, earlier foodstuff storing is placed in the case, fills water then, when pouring water water pump one end is blocked with stopping up 9.When water is piled in the case, put and cover 2 and lid 5, then open obstruction, with water pump water to be taken out, the aperture 8 at the bottom of the case of the water in the case flows to water pipe 9.After treating that water exhausts, under the barometric pressure effect, valve moves up, and covers each aperture, with case sealing, covers 2 and also lid tightening seal automatically under the barometric pressure effect of lid 5 simultaneously, has so just become the oxygen barrier antistaling box.When taking out food, open port lid 5 as long as rotate, air pours in the case, opens case port lid 2 then, just can take out fresh-keeping foodstuff from hole 3.

Claims (3)

1, little energy consumption room temperature oxygen barrier food freshness-keeping box comprises case 1, lid 2, several apertures 8 is arranged on it is characterized in that at the bottom of the case, in aperture of central authorities a valve that can move up and down 12 is arranged, valve have outward one with the water pipe of fixing at the bottom of the case 11.

2, antistaling box according to claim 1 is characterized in that an open hole 7 is arranged on case 1 end face, Kong Shangyou lid 5.

3, antistaling box according to claim 1 is characterized in that an end of water pipe 11 has a water pump 10.
