Description

A kind of refrigerator

The utility model is a kind of refrigerator.Relate to purification in the refrigerator use and fresh-keeping.

As everyone knows, refrigerator is in the use that hoards food, because food and carry the biochemical actions such as oxidation, decomposition of dirt secretly often produces peculiar smell, foul smell, vinyl gas and bacterium etc.Foul smell and peculiar smell make hoard food spoiled, taste bad, quality descends.Vinyl gas then has the heat effect of urging to foods such as vegetables, fruit, accelerates the maturing process of food such as vegetables, fruit, is unfavorable for the fresh-keeping and long term storage of food.Bacterium then makes food be damaged to the pollution of food, and people's health directly is affected.These people are made great efforts and solve.At present people solve that above-mentioned refrigerator purifies and fresh-keeping method as follows.

Aspect degerming, mainly be that the liner material of refrigerator and structural material (gasket, handle etc.) are used antimicrobial sheet material and material, in order to suppress growing and breeding of bacterium.

Removing aspect foul smell, the peculiar smell, useful thermocatalyst places in the refrigerator on defrosting heating tube, the heating film, or side placed on it, and the method (device) of removing foul smell, peculiar smell is as Chinese patent CN1035555, CN1066118, CN2356285 etc.Have in refrigerator and to place the method and apparatus that adsorbent or adsorbent type catalyst are removed foul smell, peculiar smell, as Chinese patent CN1107385, CN2330949, CN2319735 etc.The method of also favourable photoactivation agent device deodorizing is as Chinese patent CN1035438.And with the odor removal of photochemical catalyst and absorbent-type catalyst combination, as Chinese patent CN1133203 etc.

At fresh-keeping aspect, mostly adopt the method for control refrigerator temperature (speed is cold, deep cooling etc.) device, come part to solve the fresh-keeping of food.

Though above sterilization, deodorizing, fresh-keeping method all have separately characteristics and adaptability, function singleness can not reach the deodorizing (peculiar smell) of refrigerator simultaneously with a kind of method (device), sterilization and preservation.If in refrigerator, above every kind of method (functional device) is all adopted; Certainly will make the structure composition of refrigerator complicated, cost increases, maintenance and use inconvenience.And said method can not be killed the bacterium of storage space in the refrigerator, and that can not eliminate that stock produces in the refrigerator accelerating the ripening gas ethene and reach the preservation of vegetables, fruit etc.Adopt the trial of comprehensive method though people have carried out some on the purification of refrigerator and fresh-keeping function,, simplify its structure to improve the refrigerator above-mentioned functions.Promptly adopt a kind of method or device to reach deodorant for refregerator (peculiar smell) simultaneously, sterilization, fresh-keeping purpose.For example adopt the absorbent-type catalyst, deodorizing is combined with fresh-keeping function or deodorizing combines with sterilizing function, as Chinese patent CN1128858, CN2127638 etc., but its function combination is still incomplete, can not be with deodorizing (peculiar smell), fresh-keeping (removal ethene), the combination simultaneously of the multinomial function of sterilization.Simultaneously such absorbent-type catalyst adsorptivity is stronger, catalytic decomposition poor performance, and its absorption can not regenerate with the catalytic decomposition performance, and when absorption reached that its absorption is full closes capacity, with entirely ineffective, effective life, was short.

For this reason, the purpose of this utility model is that design provides a kind of collection deodorizing (peculiar smell), sterilization, fresh-keeping multi-functional for one, effectively simple, purified fresh-keeping refrigerator that can permanent use.

What the utility model adopted is the thermocatalyst method for compositions, the thermocatalyst composition that is about to have absorption and catalytic decomposition foul smell (peculiar smell), ethene and the multinomial function of kill bacteria places on the heater of heater of interior storage space of refrigerator or air circulation loop, the heat that utilizes heater to produce makes the continuous regeneration cycle of this thermocatalyst composition, absorption, catalytic decomposition, efficient catalytic decompose foul smell (peculiar smell), ethene and the kill bacteria in space in the refrigerator, the permanent purification of refrigerator, the fresh-keeping purpose of reaching.The principal character that this thermocatalyst composition is formed is that this thermocatalyst composition contains alumino-silicate, and this alumino-silicate contains Fe, Si, Al element.This thermocatalyst composition is placed on the heater of storage space in the refrigerator or air circulation loop heater, these heaters can be: the energising back is the heater element of heating directly, as resistive heater, ceramic heating element, Electric radiant Heating Film (SC) etc.; The member that closely combines with heater element is as quartz glass tube, corrugated fin, conductive metal sheet etc.; Far away apart from heater element, not contact heating element or its member, but can effectively receive the thermal-radiating freezer component and the place of heater element and member thereof.(when not heating) this thermocatalyst composition adsorbs foul smell, peculiar smell, ethylene gas during normal temperature, and slowly with its catalytic decomposition, kill bacteria simultaneously reaches the purpose of deodorizing (peculiar smell) under the normal temperature, fresh-keeping, sterilization.Close along with this thermocatalyst composition adsorbs of prolongation of normal temperature service time is tending towards full, absorption property descends gradually, i.e. deodorizing (peculiar smell) and fresh keeping property descend (bactericidal property remains unchanged).At this moment can be by refrigerator inner heating device startup work, the heat that the heater heating produces is with this thermocatalyst composition heat temperature raising.This thermocatalyst composition after the heating recovers the absorption property of its normal temperature rapidly, promptly recover deodorizing (peculiar smell), the fresh-keeping function of its normal temperature, and this thermocatalyst composition under heated condition has efficient catalytic decompose odor (peculiar smell) very doughtily, the function of ethylene gas and kill bacteria purifies with fresh keeping property stronger.So normal temperature and heated condition constantly circulate, and will remain the efficient absorption and the efficient catalytic decomposability of thermocatalyst composition, deodorizing (peculiar smell), sterilization, fresh-keeping function that can nonvolatil maintenance refrigerator.

Purification of the present utility model (deodorizing, eliminate the unusual smell, kill bacteria) fresh-keeping refrigerator and existing similar refrigerator relatively have following tangible advantage.

1. multi-functional.The employing of a kind of method (device) has the multiple function of deodorizing (peculiar smell), fresh-keeping, sterilization simultaneously, integrates three big functions.
