Description
Thereby the present invention relates to be a kind of by around vegetable compartment indirectly to vegetable box cool off can the long preservation vegetables refrigerator, the top of vegetable compartment opens wide, and with a cap covers, thereby prevents that cold air from influencing vegetables.
According to traditional habit, generally the vegetable compartment that can open and close by pulling the door open is contained in the foot of refrigerator, dress exists vegetables and the fruit in this refrigerator constantly to need to breathe between the storage life, and this breathing has increased the concentration of the ethylene gas in the vegetable compartment.
Usually, the ethylene gas scale of construction and their kinds separately that are produced by vegetables and fruit have U.S., and the gas of generations such as apple, tomato, muskmelon, Kiwi berry is more.As additive factor, also to consider the maturity of fruit, the temperature of storage area, gas ingredients and CO
2, O
2Deng content, and affact external force (being cutting force, pressure and impact) on vegetables and the fruit, these factors are had an effect with the combination of complexity usually.
When the content of ethylene gas increased, the respiration rate of vegetables and fruit increased, and the content of ethylene gas is further increased, and accelerate their ripe speed gradually.As a result, will soon occur because of chlorophyll reduces colour-darkening, the vitamin C loss, withered similar phenomenons such as (vegetables of storage and fruit are rotten), and also these phenomenons become very outstanding.Fruit became ripe situation according to following mode under, ethylene gas (for example 1ppm) just can accelerate the ripening as long as have seldom, and Once you begin becomes ripe, produces ethylene gas as chain reaction, thereby has more accelerated their maturation (finally degenerating).
As mentioned above, along with the increase of ethylene gas content, accelerated fruits and vegetables maturation and degenerate.So, recently more and more pay attention to keeping vegetables and the fresh preservation device of fruit by the content that reduces ethylene gas.
For these preservation devices, known a kind of device has adsorbent, be used for the second diluted gas in the vegetable box be adsorbed onto be placed on refrigerating chamber in and in its top vegetable box that covers roughly by a dividing plate that opens wide, or be adsorbed onto on the dividing plate.For example in the refrigerator described in the unexamined Japanese Unexamined Patent Publication No 2-71078 (1), the catalyst mix that is made of the ethylene oxide adsorbent is contained in the permeable filter, filter is placed on the place that vegetable box links to each other with refrigerating chamber.In by the disclosed refrigerator of unexamined Japanese Unexamined Patent Publication No 5-18658 (2), in the peripheral cooling air channels that constitutes of vegetable box, a permeable membrane, a heater and an ethylene gas decomposer are housed.
In above-mentioned open file (1), owing to preservation device constitutes by the ethylene gas adsorbent is mixed to be contained in the permeable filter, so price is higher.In addition, a this adsorbent ethylene adsorption gas and do not carry out oxidation, decompose and make it to be discharged into so-called purification for gas effect in the vegetable compartment to ethylene gas.Therefore, reach at this adsorbent under the situation of specified quantitative, short of adsorbent is carried out activation act, for example take out catalyst, vibration, heatable catalyst sprays hot blast or similar method, then can not reach the desired big adsorption capacity of ratio particular value.Therefore, reach after the specific adsorbance, vegetables and fruit are gone bad sooner.
In addition, in above-mentioned open file (2), for the preservation device that uses heater, it needs a permeable membrane and an ethylene gas decomposer.So, except complex structure, the cost of device itself with and upkeep cost all very high, when operation pulls the door open (promptly vegetable box is pulled out and advanced), because the collision between device, inner box and the dividing plate is easy to make device to damage.In brief, two kinds of preservation devices in the above-mentioned open file can not satisfy reliability and durability requirement.
At the initial period that holds vegetables and fruit, restriction ethylene gas content helps the long term storage to them.So, in indefinite refrigerator of the time of laying and taking out vegetables and fruit,, just can limit their and become ripe and carry out long term storage if limit ethylene gas content in the vegetable compartment for a long time.
Method for the stink of removing the refrigerator all sites, effective method comprises the ozone deodorizing method with the ozone deodorizing, the catalyst deodorizing method that carries out deodorizing later in oxidation and decompose odor with the deodorizing catalyst, the deodorizing catalyst-coated is carried out oxidation and decomposition during the Defrost heater periphery is in order to the stink of eliminating cooling period and defrosting heater deodorizing method and other similar approach.But, in any method, odor removal all is arranged in the cold air loop of refrigerating chamber, the capacity of refrigerating chamber is big, and slightly disagreeable taste arranged, and odor removal is used for removing the foul smell in the cold air that turns back in the refrigerating chamber, therefore just can not be to carrying out deodorizing with the gas in the vegetable compartment (exactly being vegetable box) of cap covers and cooling indirectly.Like this, in case draw back and close when pulling the door open, will leak the insufferable stink of seller in the vegetable box.
Stink in the vegetable box (unpleasant component) mainly is methyl mercaptan, trimethylamine etc.When resembling garlic, radish, onion, very easily generate methyl mercaptan when fresh vegetables such as leek and cabbage degenerate, and trimethylamine is comprised in the tastes such as the onion that degenerates, cabbage.Even the content of methyl mercaptan and trimethylamine is seldom, 0.001ppm for example, their taste also allows the people be difficult to stand.
The present invention be directed to that these problems make, the object of the present invention is to provide a kind of refrigerator that has preservation device, this device can not only absorption, oxidation and decomposition ethylene gas, and the foul smell that produces in energy absorption, oxidation and the decomposition box, an opening is arranged above this box, and this opening is exactly the opening of vegetable compartment.
