Referring to Fig. 1, Fig. 2 and Fig. 3, food fresh keeping cupboard of the present utility model comprises a cupboard body 1, and a pair of 2, three at the cupboard door that is articulated on the described cupboard body 1 is fixed in shelf 3A, 3B and the 3C on the described cupboard body 1.On described shelf 3B, 3C, shelve a crisper 4A, 4B respectively, on described cupboard body 1, shelved another crisper 4C.Between the crisper 4B of crisper 4A up and centre, middle crisper 4B and below respectively have a sebific duct 5A and 5B to stretch out from the opposite face of described adjacent crisper and to be communicated with between the crisper 4C with it hard tube couple together, on described sebific duct 5A and 5B, accompany a clip 6A and a 6B.On the top of the box body 8 of crisper 4A, 4B and 4C, be equipped with rectangle or the tank foursquare, " U " shape section of a corral around the rectangle or the big fenestra of the square outside, deposited water 12 in the groove, being inserted in by its outer rim in this groove is the big capping 9 that central authorities offer pros or circular little fenestra, on its top, also offer a rectangle or foursquare, fall the tank of " π " type section, also deposited water (similar) in the groove with situation shown in Figure 3, covering is small cover 10 in this groove, and a handle 11 is arranged on it.

On shelf 3A above the described fresh-keeping cabinet, (available arbitrary method commonly used) carbon-dioxide generator 7 has been installed.As shown in Figure 4, described carbon-dioxide generator comprises a circle or square casing 13, lower clapboard 14 and upper spacer 15, deposit cooling water 20 in the upper space between the top of upper spacer 15 and housing 13, in cooling water 20, pass through a snakelike metal tube 19, intermediate space with described generator 7 of this pipe is communicated with, and upper space is then stretched out in the other end; In described intermediate space, put an inside and be contained in the chemicals such as the sodium bicarbonate that can split the carbon dioxide off under the low heating-up temperature, (Na HCO putting on the lower clapboard 14 ₃) drawer 17 that 18 top is opened wide, this drawer can freely be pulled out propelling, can make after the propelling to keep good air tightness (as utilizing common method such as magnetic strip of paper used for sealing) between housing 13 surfaces of itself and generator 7; In the lower space of described housing 16, can pack into just like a heating wire with easy access or spill the heating source of smart lamp and so on.

Thereby above-mentioned carbon dioxide food fresh keeping cupboard be utilize carbon dioxide proportion greater than the character of air can emptying, replace air among described crisper 4A, 4B and the 4C and provide and be suitable for store food and fresh-keeping this principle of environment is made.During first the use, open described clip 6A and 6B, open three small covers 10 again, output sebific duct in the outlet of carbon dioxide steel cylinder (can buy from market) of pressure reducer will be housed then lead to the fenestra in the big capping 9 on the below crisper 4C into, carbon dioxide gas is sent constantly into.Along with carbon dioxide gas below among the crisper 4C by bottom constantly charging into to the top, air is constantly extruded from fenestra, when at the combustion flame (putting a candle of lighting or a match) at fenestra mouth place when extinguishing, then be full of carbon dioxide gas among the crisper 4C of explanation below, can cover small cover 10 this moment.Rely on " π " type cross section tank that falls in the big capping 9 can keep the excellent sealing state of below crisper 4C.When in crisper 4C, being full of carbon dioxide gas, remaining in the crisper that the sebific duct 5B at top and the air in the hard connecting leg also be driven into the top basically and suffered.At last with on the clip 6B folder.The same manner is full of carbon dioxide gas with middle crisper 4B again, and folder is gone up clip 6A again.At last, be full of top crisper 4A again, cover small cover 10 respectively.

When carrying out above-mentioned inflation, also can with purchase the carbon dioxide that comes charge in advance once measured, in the container that equates (passing in and out the capsule of pipe as double headed roller) of its volume and a crisper 4A or 4B or 4C, and then once charge into wherein in the safety box, residual air is arranged also is seldom even so also can protect the top of levying in each safety box basically.

(as food hour) can be put into or take out to food from the fenestra in the big capping 9, maybe can take off big capping 9, puts into or take out the big fenestra on safety box 4A or 4B or 4C when big (as food).Because every interior gas concentration lwevel of crisper will hang down at the top in hole near the window comparatively speaking slightly, so the length difference of resting period is deposited from lower to upper and is advisable as required.

In general, only owing to leak and the diffusion when uncapping can cause the loss of a certain amount of carbon dioxide.Therefore, to replenish carbon dioxide gas in use for some time, need only the carbon dioxide gas of the amount more than 80% that maintains among every crisper 4A or 4B or the 4C, then be lower than 5%, satisfy the food fresh keeping condition with regard to touching the oxygen content that makes in this box.Through test, as being full of carbon dioxide gas in one 600 * 600 * 500 millimeters the casing, continue three minutes as opening wide 1/4th tops every day, then need to replenish the carbon dioxide gas of diffusion part after five days.As every cubic metre of carbon dioxide gas of connecting to neutral price is 0.60 yuan of calculating, then only changes expense 0.43 minute every day, (except the investment buying carbon dioxide steel cylinder expense) so, very inexpensive.

In addition, as interrupting because of the carbon dioxide gas source of goods or when having no way of to buy carbon dioxide gas, can be in the carbon-dioxide generator in the described fresh-keeping cabinet 7, put into certain thermal source (as heating wire or spill smart lamp etc.), sodium bicarbonate (the Na HCO in the drawer 17 is deposited in heating ₃), the gas that can split the carbon dioxide off is emitted after water 20 coolings from snakelike metal tube 19.In coiled pipe 19 outlets, connect a sebific duct (not shown) that accompanies clip, can directly from the fenestra of top safety box 4A, charge into, to replenish part because of sewing or spreading with it.

When above-mentioned any mode is replenished, need the small cover 10 on clip 6A, 6B and crisper 4B, the 4C is opened, quantitatively charge into the metering capsule then.Thing finishes, and clip 6A and 6B on the folder cover three small covers 10.
