Abstract

The utility model relates to a food preserving box belonging to the technical field of food preserving. The utility model comprises a housing, a chamber door, a food shelf, a burner and a ventilation fan. The burner is on one side of the housing, and is composed of an oval piston and a cylinder body matched with the oval piston. A snorkel I and a snorkel II are installed in the cylinder body. A venthole respectively installed at the top and the bottom of the housing is connected with the snorkel I and the snorkel II in the cylinder block. The ventilation fan is installed in the snorkel I. A cold water pipe is sheathed outside the snorkel II. The utility model becomes low pressure, less oxygen or no oxygen by burning and consuming oxygen in the box to maintain the freshness of food.

Description

Food freshness-keeping box

The utility model relates to a kind of food freshness-keeping box.

Fruit, vegetables etc. are placed the long time in air, rot easily.The extensive use refrigerator is preserved food now, prevents that it from rotting.But the refrigerator consumed power can't use in the area of short of electricity.Because the food process is freezing, cell can form the liquid ice crystal, has changed the food freshness, makes food can not keep original delicate flavour again.

The purpose of this utility model provides a kind of food freshness-keeping box, and it does not promptly need consumed power, and food is not freezing again, just reaches to prevent to rot, and keeps the purpose of original delicate flavour.

The purpose of this utility model is achieved in that

A kind of food freshness-keeping box, comprise casing, chamber door, food rack, burner and ventilation fan, wherein burner is in a side of casing, form by an ellipse garden piston and a cylinder body that is complementary with it, breather pipe I and II are housed on the cylinder body, the top of casing and bottom have respectively that breather pipe II and I link on a passage and the cylinder body, in the breather pipe I ventilation fan are housed, and the outside of breather pipe II is with cold water pipe.

There are a combustion chamber and a passage in the top of going up of the cylinder body of antistaling box, covers on the combustion chamber bimetal leaf is housed, and loam cake links to each other with the power supply of ventilation fan, central authorities are down taper, several passages that evenly distribute all around, the cylinder body center is the tourus cavity, an end of cylinder body is one and filters mouthful.

In the ellipse garden shape piston of antistaling box a cavity is arranged, be fuel chambers, have a passage to communicate with the combustion chamber, one combustion front is arranged at the fuel chambers top, and the combustion front center is a passage, and several apertures evenly distribute around the passage, wick is housed in the aperture, and piston one side has handle.

The tourus of antistaling box is packed in the ellipse garden cavity of piston cylinder, and the piston combustion face matches with cylinder body upper combustion chamber and links to each other with the breather pipe II, and the passage on piston upper vent hole and the piston cylinder matches, and links to each other with the breather pipe I, and bimetal leaf is above wick.

On the chamber door of antistaling box rubber gasket is arranged, the power supply of ventilation fan is a direct current.

Under air-tight state, utilize alcohol burning to consume oxygen and make that Main Ingredients and Appearance is gases such as nitrogen, carbon dioxide in the air.Because anoxic in the case makes food be in anticorrosion state fully, can not go bad, thereby reach the long-period freshness preserving purpose for the bacterium corruption, because the utility model without alternating current, is promptly saved power consumption, enlarged the scope of application again again, power-shortage area also can be extensive use of.

Provide embodiment of the present utility model below in conjunction with accompanying drawing:

Fig. 1 is an overall structure schematic diagram of the present utility model;

Fig. 2 is the structural representation of piston cylinder of the present utility model;

Fig. 3 is an ellipse garden of the present utility model structure of piston schematic diagram;

Fig. 4 is a combustion chamber loam cake schematic diagram;

Fig. 5 is a piston combustion face schematic diagram.

A kind of food freshness-keeping box, comprise casing 1, chamber door 2, food-shelf 4, fuel-device 7 and ventilation fan 8, wherein burner 7 is positioned at casing 1 one sides, form by ellipse garden piston 22 and the piston/cylinder 12 that is complementary with it, breather pipe I 6 and breather pipe II 10 are housed on the cylinder body 12, and a passage 11 and 5 are respectively arranged at the top of casing 1 and bottom, and passage 5 links with breather pipe I 6, passage 11 links with breather pipe II 10, and the outside of breather pipe 10 is with cold water pipe 9.

There are a combustion chamber 14 and passage 19 in the top of going up of piston/cylinder 12, on the loam cake 18 of combustion chamber 14 sheet metal 15 is housed, loam cake central authorities are down taper 16, and several passages 17 all around evenly distribute, the cylinder body center is an ellipse garden cavity 13, and an end of cylinder body is one and filters mouth 20.

In the ellipse garden shape piston 22 cavity being arranged is fuel chambers 23, has a passage 28 to be connected with fuel chambers 23, and a combustion front 27 is arranged at fuel chambers 23 tops, combustion front 27 centers are a passage 26, several apertures that evenly distribute all around are equipped with wick 25 in the aperture, piston 22 1 sides have a handle 21.

Ellipse garden piston 22 is packed in the cavity 13 of piston cylinder 12, and piston combustion face 27 coincide with combustion chamber 14 on the cylinder body, links to each other with the breather pipe II, and passage 28 on the piston 22 and the passage 19 on the piston cylinder match, and link to each other with the breather pipe I.Rubber gasket 3 is arranged on the chamber door 1, and the power supply that changes fan 8 is a direct current, and alcohol is housed in the fuel chambers.

On the chamber door of food freshness-keeping box rubber gasket is arranged.

Food is put into the utility model antistaling box, close upper chamber door 1, catch handle 21 to pull out the ellipse garden piston 22 of burner 7, light wick 25, piston 22 is advanced in the cavity 13 of cylinder body 12, wick 25 burns in combustion chamber 14.Sheet metal 15 expanded by heating of wick 25 tops, connect the power supply of ventilation fan 8, ventilation fan 8 begins to rotate, accelerate air circulation in the case, air in the casing 1 enters fully burning in the combustion chamber 14 of burner 7, remaining CO from the passage 5 of bottom in the fuel chambers 23 from piston by breather pipe I 6 and passage 19,28 ₂, N ₂Enter in the breather pipe I 10 Deng the passage 17 of gas around combustion chamber loam cake 18, after the cold water pipe cooling, enter in the case by case top passage 11, make to form few oxygen of low pressure or anaerobic state in the case, thereby reach the purpose of food fresh keeping, wick is under anaerobic state, naturally extinguish, bimetal leaf disconnects, circuit interruption, and ventilation fan quits work.

Before opening the door, pull out piston earlier, outside air mouthfuls 20 filtered and enters in the passage 19 of cylinder body after filtration, by breather pipe I 6 through the passage 5 of bottom with enter in the case, inner and outer air pressure is equated, open the door then.After finishing using, refire wick 25, push in the cylinder.

Can place activated carbon on the food-shelf, peculiar smell that distributes to assimilate food and airborne humidity.
