Below, with reference to accompanying drawing an embodiment of the invention are described.Fig. 1 is the profilograph of refrigerator of the present invention, be provided with refrigerating chamber (2) at topmost, be provided with a little higher than refrigerating chamber of temperature in the below of this refrigerating chamber (2) by dividing plate and remain on the vegetable compartment (3) of high humility with the inner storage space of the refrigerator main body of heat insulating box (1).Below in vegetable compartment (3) is switched temperature by heat insulation next door to divide about chamber (4) and ice making storage chamber not shown in the figures and is set up in parallel, and is provided with separately to be divided into the refrigerating chamber (5) of 2 parts up and down on foot.
The front openings portion of each storeroom is provided with special-purpose separately loose-leaf and realizes closing, simultaneously, by the refrigeration on the back side separately that is arranged on refrigerating space and reefer space with condenser (6) and freezing with condenser (7) and near the fan (8) (9) and the pipeline that are arranged on each condenser, make circulating cold air, each storeroom be cooled and control to the temperature of setting.
On the lower backside of the reefer space that the foot of refrigerator main body (1) is provided with, be formed with the space, Machine Room, and be provided with to above-mentioned refrigeration with and freezing compressor (10) with condenser (6) (7) the supply system cryogen.
In addition, in the cold air stream (12) that the vegetable compartment (3) of the diapire outside of the low temperature housing (11) that is provided with above-mentioned refrigerating chamber (2) below is communicated with, be provided with odor removal (13).Schematic configuration as shown in Figure 2, this odor removal (13) has photocatalyst module (15) and ozone decomposition catalyst (16), is used for being adsorbed on the smelly molecule that cold air contained of circulation in the path (12) and organic substance to carry out deodorizing.
In photocatalyst module (15), on the surface by matrix with porous ceramics such as aluminium oxide or silica, 2 are fixed with the titanium oxide is optical catalyst filter (17) adjacency of the photocatalyst particles of representative, between this optical catalyst filter, uprightly be provided with and form latticed sparking electrode (18) by thin plates such as etching stainless steels, simultaneously, on the windward and downwind side of above-mentioned 2 optical catalyst filters (17) (17), be respectively equipped with above-mentioned sparking electrode with the same manner form to electrode (19) (19).
(20) be power circuit, utilize high pressure generation transformer (21) between above-mentioned sparking electrode (18) and each are to electrode (19), to apply positive pulse type dc high voltage, by such structure, sparking electrode (18) and electrode (19) played a role as the discharge cell of ultraviolet ray generation usefulness, between both sides' electrode discharge taking place and producing wavelength is ultraviolet ray smaller or equal to 380nm.In addition, (22) are fan, are used to promote that the cold air in the cold air path (12) circulates and the reinforcement deodorization, but also can be provided with especially.
In above-mentioned odor removal (13), apply voltage to power circuit (20) energising and at sparking electrode (18) with between to electrode (19), thereby between electrode, discharge, the ultraviolet ray that produces shines on the optical catalyst filter (17) (17), thereby make the photochemical catalyst activation, the strong oxidation of the hydroxide free radical (free radical) by the active oxygen that produces, to decomposing, by carrying out odorlessization or low foul smellization is carried out deodorizing attached to the lip-deep foul smell composition of optical catalyst filter (17) (17) and the combination of organic compound.
In addition, carry out making the bacterial cell membrane embrittlement antibiotic in, by oxygenolysis, suppress the microorganism on optical catalyst filter (17) (17) surface, particularly have a liking for the breeding of oxygen bacterium, can decompose the dirt of removing odor removal (13) and storeroom wall surface.
If the oxidation Decomposition odorous substance, then the organic substance carbon that must have is oxidized and produce carbon dioxide.Usually we know, the vegetables of band leaf absorb oxygen by breathe air, and freshness is reduced, and still, carbon dioxide has the effect of the breathing of the vegetables that suppress above-mentioned band leaf, and freshness is kept thus.Especially, because photochemical catalyst has strong oxidation, so help to produce a large amount of carbon dioxide by oxidation Decomposition.
In addition, in utilizing the odor removal of above-mentioned photochemical catalyst (13), the deodorization that not only has the oxidation Decomposition of utilizing odorous substance, and have from generation such as fruit and make that the promptly aging hormone of food maturation is the effect that ethene decomposes, by this ethene decomposition, also can obtain to keep the effect of food freshness.
In addition, this sparking electrode (18) and when electrode (19) discharged, because produce ultraviolet ray and ozone simultaneously, so having, above-mentioned photocatalyst module (15) produces the function of active oxygen by ultraviolet ray with decomposing organic matter matter, also has simultaneously function as the ozone generating unit, react by mixing mutually, can carry out oxidation Decomposition to the foul smell composition thus and come deodorizing with ozone that generation contains the cold air of foul smell composition.
From the downwind side of this photocatalyst module (15), be provided with by the formed ozone decomposition catalyst of cellular sintered body (16) every preset distance, to decompose the residual ozone that does not directly flow down more than or equal to predetermined value with the ozone substance reaction based on manganese dioxide.In addition,, not only can utilize above-mentioned photocatalyst module (15), also can utilize the mode or the electrolysis mode of combination creeping discharge electrode and high-tension transformer as the ozone generating unit.
As mentioned above, produce ozone by the sparking electrode (18) in the odor removal (13) with to the interelectrode discharge of electrode (19) etc., the temporary transient ozonize of airborne oxygen in the storeroom, react with odorous substance (organic matter), like this, become the intermediate product of partial oxidation sometimes, but also can further be separated into carbon dioxide and water, consequently, can consume the indoor oxygen of seal storage and its concentration is reduced.
Yet in present refrigerator, the amount of the volatile materials that is used for reacting with ozone, for example ethene, ethanol, acetaldehyde etc. is less, in most of the cases, can not obtain to make the effect of the level that oxygen concentration reduces.
Therefore, by being to be provided with between photocatalyst module (15) and the ozone resolving cell (16) to contain the filter that carbon is material (23) at ozone generator, ozone that produces and carbon react and become carbon dioxide, can under the condition of basic Maintenance free, simply storeroom be formed the atmosphere of hypoxemia, high carbon dioxide thus.
Carbon such as active carbon are that the form of material has granular or crushed material etc., when considering the miniaturization and the pressure loss, be core with the cellular thing of pottery system or honeycomb metal thing preferably and active carbon etc. is fixed on the above-mentioned core.
When using with form such as granular or crushed material, can keep by in odor removal (15), retainer being set, in addition, be material by using the good carbon of adsorptivity such as active carbon, can further improve the deodoriging properties in the refrigerator.In addition, as the resolving cell of residual ozone and when using ozone decomposition catalyst (16), by active carbon is set, react with the remaining ozone that arrives ozone decomposition catalyst, make its minimizing, then can prevent to contact, further life-saving with the ozone more than or equal to required of ozone decomposition catalyst (16).
In addition, if it is first-class and integrated that carbon such as above-mentioned active carbon are that material is carried on photocatalyst module (15),, the atmosphere of hypoxemia, high carbon dioxide can be set simply then by the oxidation of ozone and active carbon.In addition, the adsorption capacity of photochemical catalyst is lower, but owing on photochemical catalyst, carry the high active carbon of adsorption capacity, thus, the odorous substance that is carried on the active carbon is decomposed owing to for example being fed to titanium oxide, so the deodoriging properties of photocatalyst module is improved.
Opposite with above-mentioned situation, also can make carbon such as active carbon is to contain photochemical catalyst in the material.Be that active carbon has higher adsorption capacity to various odorous substances, also be widely used at present as the adsorbent in the deodorant.Therefore, if in odor removal, active carbon is set further, then can further improve deodoriging properties with ozone generating apparatus and ozone resolving cell.Above-mentioned active carbon does not have capacity of decomposition for adsorbed odorous substance, if its surface is covered by odorous substance, then the absorption affinity of foul smell molecule disappears, and has also just lost deodorizing capability.
Therefore, by mixed oxidization titanium in active carbon and to the titania surface irradiation ultraviolet radiation, odorous substance is fed to titanium oxide and decomposes, and therefore can continue the ability of adsorbent.The light source of this moment be the non-direction ultraviolet that radiates from above-mentioned space discharge mechanism, perhaps utilizes ultraviolet lamp etc. also to be fine.The oxidation reaction of the photochemical catalyst by active carbon can produce the carbon dioxide of the freshness that helps keeping vegetables and fruit, helps to improve the concentration of carbon dioxide in the storage space.
In addition, replacing above-mentioned photochemical catalyst, is to add noble metal in the filter (23) of material also to be fine at carbon such as containing active carbon.As mentioned above, active carbon does not have the capacity of decomposition of odorous substance, if its surface is covered by odorous substance, then absorption affinity disappears, and has also lost deodorizing capability.Simultaneously, because the ability of absorption ozone also reduces, so its result, the growing amount of the carbon dioxide that oxidation reaction produced that is undertaken by the combination of carbon and ozone reduces.
Therefore, by will be in air seldom oxidized and noble metal, for example Mn, Fe, Co, Ni, Ag, Pt, Pd, Rh etc. that have a catalyst action be added in the filter that carbon such as containing active carbon is material, make odorous substance be fed to above-mentioned noble metal and decompose, thereby can continue the ability of adsorbent.In addition, above-mentioned noble metal also can be used as the oxidation reaction catalyst of carbon and ozone and plays a role.
In addition, relevant with the foregoing description, be to add pottery in the filter of material also to be fine at carbon such as containing active carbon with catalyst action.By in having the pottery of catalyst action, adding TiO
2, ZrO
2, SiO
2Deng oxide or their composite oxides, odorous substance is fed to pottery and decomposes, thereby can continue the ability of adsorbent, and with above-mentioned same, can play a role as the oxidation reaction catalyst of carbon and ozone.
In addition, carbon such as above-mentioned active carbon are that material passes through ozone or photochemical catalyst etc. and oxidized, and when active carbon was all consumed, in order further to produce carbon dioxide, being necessary to replenish carbon such as active carbon was material.If above-mentioned active carbon etc. is arranged to dismountable form from odor removal, commercially available activated charcoal deodorants etc. is arranged to boxlike type (cartridge type) and replaceable, and active carbon etc. is used with granular or pulverized shape, can easily carry out in special-purpose retainer, replenishing the part that consumed etc.
Below, to the ozone resolving cell or can to contain carbon to the flow direction be that other embodiments of the invention that the cold airflow of the filter of material switches describe.
Under the situation of filter deployment shown in Figure 2, the ozone that produces in ozone generating apparatus (15) is that the filter (23) of material contacts with carbon such as containing active carbon usually, owing to the oxidation reaction that continues to carry out carbon and ozone promotes that carbon is the consumption of material, contain the filter that carbon is material (23) so be necessary to change, can need to safeguard.
In addition, usually under the atmosphere of hypoxemia, high carbon dioxide, the breathing of vegetables is suppressed, but when the atmosphere overrich of carbon dioxide, vegetables can go bad sometimes on the contrary.Therefore, the carbon in the preferred filters (23) is not that material is oxidized to more than or equal to required degree, thereby produces the carbon dioxide more than or equal to required degree.
In addition, for ozone decomposition catalyst (16),, preferably on more than or equal to required degree, do not contact with ozone owing to can make the catalyst function deterioration yet.
Therefore, adopt the shown in Figure 3 of identical symbol as the parts identical with Fig. 2, in the 2nd embodiment, to contain carbon and be the filter (23) of material and ozone decomposition catalyst (16) and be arranged on wind path (12) when interior with series system, be provided with by carbon be the stream of filter (23) of material side and blocking-up this filter (23) side not by and the stream (24) of ozone decomposition catalyst (16) side that directly leads, and can to utilize the stream switch unit be that damper (25) etc. switches.
In addition, similarly, as the 3rd embodiment, as shown in Figure 4, also can be set up in parallel in wind path (12) containing filter that carbon is material (23) and ozone decomposition catalyst (16), utilize above-mentioned same damper (25), the cold airflow that the flow direction is contained filter that carbon is material (23) and ozone decomposition catalyst (16) switches.In addition, can be that the downstream of the filter (23) of material side further is provided with ozone resolving cell (16 ') at carbon this moment also.
As above-mentioned Fig. 3 and shown in Figure 4, in wind path (12), by ozone generating apparatus (15), ozone decomposition catalyst (16) being set and containing the filter that carbon is material (23), except the deodoriging properties of the ozone that utilize to produce and ozone decomposition catalyst (16), by carbon is the absorption property of material and deodoriging properties is significantly improved, and can regulate by containing the ozone amount of the filter that carbon is material (23) by enough dampers (25) simultaneously.Thus, can prevent that blocking is the consumption that material causes because of ozone oxidation, life-span of the ozone of ozone decomposition catalyst (16) is prolonged.
Damper (25) is that the detected value of the sensor etc. by detecting all gases concentration in the storeroom and temperature, humidity carries out to the ozone resolving cell (16) of said structure and the switching that contains the filter that carbon is material (23), thereby control cold air is to ozone resolving cell (16) with contain the throughput of the filter that carbon is material (23).For example, detect the amount of the carbon dioxide in the storeroom, utilizing damper (25) changing flow direction carbon by detected value is the air quantity of the filter (23) of material side, perhaps controls the ozone amount that flows to decomposition catalyst (16) with adjusting by the rotating speed that changes fan (22).
According to as mentioned above, can control the oxidation reaction of the carbon that utilizes ozone, can prevent to contain the consumption more than or equal to required carbon in the filter that carbon is material (23), the while can be controlled amount of carbon dioxide and will be adjusted to the concentration that is fit to vegetables in the storeroom.In addition,, can effectively be controlled at absorption, the decomposition reaction of the ozone decomposition catalyst (16) that depends on these values to a great extent, therefore can realize effective deodorization, and can prolong life of catalyst by detecting humidity and temperature.
Fig. 5 represents the 4th embodiment, and the symbol mark is the same.For ozone generating apparatus (15), be set up in parallel ozone decomposition catalyst (16) below in the wind path (12) in downstream and contain the filter that carbon is material (23), utilizing the stream switch unit is damper (25), can be that the stream of filter (23) side of material side switches to ozone decomposition catalyst (16) side with by carbon.
The molecular weight of ozone is 48, mean molecule quantity 27 than air is big, therefore, ozone has in air owing to difference in specific gravity and to the character of sinking, as shown in the figure, ozone decomposition catalyst (16) is set below wind path (12) and contains the filter that carbon is material (23), even fan (22) is not set so specially, ozone also can flow downward naturally and contact with catalyst (16) and filter (23) respectively, therefore can realize the miniaturization of wind path (12), and can reduce cost.
As the 5th embodiment, with above-mentioned same, as shown in Figure 6, for ozone generating apparatus (15), the ozone decomposition catalyst (16) that is set up in parallel in the downstream of wind path (12) and containing in the filter that carbon is material (23), be respectively equipped with fan (22a) (22b), utilizing the stream switch unit is damper (25), is that the cold air stream of filter (23) side of material side is controlled in switchable mode to ozone decomposition catalyst (16) side with by carbon.
According to as mentioned above, the fan (22a) of ozone decomposition catalyst (16) usefulness is when for example the concentration of the odorous substance in refrigerator (2) rises, being located at indoor gas sensor not shown in the figures detects above-mentioned concentration and exports, utilize damper (25) to open stream, increase the rotating speed of said fans (22a) simultaneously, make indoor odorous substance forcibly by and be adsorbed onto on the decomposition catalyst (16), thereby promote and the reaction of ozone, can shorten indoor deodorizing speed.
In addition, for carbon such as containing active carbon is the fan (22b) of filter (23) usefulness of material, surpass under the situation of the necessary normal concentration of fresh-keeping of vegetables at for example indoor gas concentration lwevel, preferably after this active carbon is contacted with oxidation Decomposition with ozone, this is because can to make carbon such as containing active carbon be to shorten in service life of the filter (23) of material.
For the vegetables that have suitable gas concentration lwevel separately, concentration of carbon dioxide is increased to more than or equal to desired concn, neither be good from the fresh-keeping viewpoint of vegetables self.For this reason, control the rotating speed of said fans (22b) by utilizing gas concentration lwevel in the sensing chamber such as gas sensor, utilize damper (25) to switch the cold air stream simultaneously, the contact rate of adjustable activity charcoal and ozone thus, more appropriate deodorization can be carried out, and life of catalyst can be prolonged.
For sensor, except the above-mentioned gas sensor, also can adopt temperature sensor, humidity sensor, pressure sensor etc.In addition, also can not sensor output, but control by the time of timer that said fans also can be arranged on weather side.
As other other embodiment, the running rate of control ozone generating apparatus (15) also is fine.Same as the previously described embodiments, for carbon such as ozone decomposition catalyst and active carbons is material, because must control contact rate simultaneously with ozone, so ozone decomposition catalyst (16) or when containing in one of any in the filter that carbon is material (23) by ozone, control the running rate of ozone generating apparatus (15) in the mode that can carry ozone amount necessary in each autoreaction, when both sides are blown simultaneously, for filter (16) (23) is separately carried necessary total ozone amount, need to improve running rate.
Therefore, ozone decomposition catalyst (16) and the life-span of containing the filter that carbon is material (23) can be prolonged, along with separately oxidation, decomposition reaction and control, in addition, in the time of control stream switch unit (25), make the running rate of ozone generating apparatus (15) change, can obtain efficient and appropriate deodoriging properties thus.
In addition, in the above-described embodiments, although be illustrated for the structure on the cold air path of the partitioned portion that odor removal (13) is arranged on refrigerating chamber (2) and vegetable compartment (3), but, the invention is not restricted to this, even be configured in refrigerating chamber or other storage space, also can obtain same effect.
The present invention can be used in the refrigerator of the long preservation that possesses odor removal and oxygen concentration reduction unit and seek food.
