Description
Technical field
The present invention relates to a kind of refrigerator, particularly relate to a kind of taste removal low rime ice case.
Background technology
Along with raising and the living-pattern preservation of people's living standard, refrigerator, in people live, plays the most important role.Consumer is no longer limited to preservation food to the requirement of refrigerator, and wishes that refrigerator can be good at keeping the nutrition of food, brings health.
Under the such sealed environment of refrigerator, the odor dispersion of various foods is not gone out, and accumulates in refrigerator, produces the abnormal flavour allowing people detest.
And the method tackling abnormal flavour at present mainly has two kinds.
The first is absorption method, by adding some there is adsorbing material and device reaching the target of refrigerator taste removal, but this kind of scheme on the one hand adsorbent is the most respond well in initial period taste removal, effect declines until adsorbing and saturated the most no longer playing function of odor removal always subsequently, the most automatically desorption causes secondary pollution, and on the other hand adsorbent needs to change, and cost is high and not environmentally, or need the most manually desorption, poor user experience.
The second is oxidizing process, the modes such as ionization, ozone, catalyst are used to be aoxidized by odor molecules, but owing to ice the temperature inside the box is relatively low, oxidation is not exclusively, product still has the material that part is harmful, even and if end product, element sulphur, nitrogen element conservation, remain oxysulfide, nitrogen oxides is gathered in refrigerator, has certain impact to food and human body.
Simultaneously, owing to air cooling refrigerator evaporator temperature is relatively low, cold air can a large amount of frostings thereon through vaporizer, affect cold conduction efficiency after frosting, need periodically to carry out heating defrost, after defrost, vaporizer surrounding space is in high temperature, high humidity state, at cooling cycle following closely, high humidity, high-temperature gas deliver to refrigerator everywhere, make energy consumption of refrigerator increase.
In view of this, it is necessary to existing refrigerator is improved, to solve the problems referred to above.
Summary of the invention
It is an object of the invention to provide a kind of refrigerator, there to be the problem of abnormal flavour in thoroughly solving current refrigerator, solve the problem that current refrigerator energy consumption is excessive simultaneously.
For achieving the above object, the invention provides a kind of refrigerator, including room between storing, vaporizer, cold dry air through vaporizer is introduced the intake air way of room between described storing, damp-heat air indoor between described storing is introduced the air-return duct of described vaporizer and in order to remove abnormal flavour in described refrigerator and to reduce the taste removal low frost device of frosting degree, described taste removal low frost device includes purification moisture absorption unit and the exhaust apparatus being placed in air-return duct, wherein, described purification moisture absorption unit is in order to adsorb odor molecules, hydrone and after being heated by odor molecules oxidation Decomposition, hydrone is desorbed, described exhaust apparatus is in order to by odor molecules, steam is discharged outside described refrigerator.
As a further improvement on the present invention, described purification moisture absorption unit is placed on the bottom of described air-return duct, and described purification moisture absorption unit includes inhaling taste hygroscopic material, catalysis oxidation material, to adsorb odor molecules and hydrone at low temperatures, oxidation Decomposition odor molecules be desorbed out steam under high temperature.
As a further improvement on the present invention, described refrigerator also includes the heater strip arranged near described vaporizer with described purification moisture absorption unit, described heater strip is described vaporizer and the heating of described purification moisture absorption unit, so that the frost on described vaporizer is liquefied as defrosting water, absorption is become odorless gas in the odor molecules oxidation Decomposition purified on moisture absorption unit, is desorbed the hydrone purifying the absorption of moisture absorption unit for steam simultaneously.
As a further improvement on the present invention, described refrigerator also includes being positioned at below described heater strip with the discharge outlet discharged by described defrosting water.
As a further improvement on the present invention, described exhaust apparatus includes being opened on described refrigerator back and being connected with described air-return duct fresh air outside introduces the air inlet in described air-return duct and described heater strip heats the hot and humid gas of described vaporizer generation and heats oxidation product produced by described purification moisture absorption unit and the air extractor outside the steam described refrigerator of discharge.
As a further improvement on the present invention, described air extractor is placed on the lower section of described discharge outlet, and includes the exhaustor being connected with described discharge outlet and be arranged on extraction fan or the air pump of described exhaustor one end.
As a further improvement on the present invention, described discharge outlet, described air inlet and described exhaustor are provided with unidirectional stop valve.
As a further improvement on the present invention, described purification moisture absorption unit is respectively ventilated membrane from inside to outside, can adsorb inhaling taste hygroscopic material, playing the catalysis oxidation material of catalytic action of odor molecules and hydrone.
As a further improvement on the present invention, the return air direction in the most described air-return duct of described air inlet opening in air-return duct.
The invention has the beneficial effects as follows: due in air-return duct rich in the odor molecules brought by room between each storing, hydrone, if these odor molecules directly contact cryogenic vaporizer with hydrone, vaporizer will be enriched with abnormal flavour and frost in a large number.Purification moisture absorption unit is arranged in air-return duct by the refrigerator of the present invention, is the most adsorbed before odor molecules, hydrone touch cryogenic vaporizer, can more fully realize taste removal, low frost；Then utilize defrost waste heat, can be by the odor molecules oxidation Decomposition being adsorbed onto on purification moisture absorption unit, by hydrone desorption, and by exhaust apparatus, the high humidity height hot-air that oxidation product, the steam of desorption and the vaporizer defrost after the odor molecules decomposed the most completely, oxidation produces together is discharged outside refrigerator, thus in thoroughly solving refrigerator, have the problem of abnormal flavour, reduce frosting degree.
