And then, composition voltage application portion 133 near atomization portion 139, the nagative potential side of the voltage application portion 133 producing high-tension electricity electrically connects with atomizing electrode 135, and positive potential side electrically connects with comparative electrode 136.

Near atomization portion 139, owing to spraying, often produce electric discharge, so in atomization portion 139 front end, abrasion may be produced.Between the longer-term that freezer 100 would generally operate more than 10 years, it is therefore necessary to the surface of atomization portion 139 is carried out surface process, for example, it is preferable to use nickel plating and gold-plated or platinum plating.

Comparative electrode 136 by being such as made up of rustless steel, and, it is necessary to ensure that its long-term reliability, especially for prevent adhere to impurity, prevent dirt, preferably carry out such as platinum plating etc. surface process.

Voltage application portion 133 communicates with the control unit 146 of freezer main body, is controlled, and according to from freezer 100 or the input signal of sprayer unit 131, carries out unlatching (the ON)/stopping (OFF) of high voltage applying.

Below, for the freezer 100 of the present embodiment of said structure, its action, effect are described.

First, the action of freeze cycle is described.Freeze cycle is according to the temperature of the setting in freezer, according to the signal from control substrate (not shown), carries out action, performs cooling operating.The cryogen of the High Temperature High Pressure sprayed by the action of compressor 109, condensation liquefaction is to a certain degree being obtained by condenser (not shown), and then, cryogen pipe arrangement 112b etc. via the front scope being arranged in the side of heat insulating box 101 as freezer main body, the back side or heat insulating box 101, while preventing the condensation of heat insulating box 101, carry out condensation liquefaction, reach capillary pipeline (not shown).Thereafter, in capillary pipeline, carry out heat exchange with the suction tube (not shown) being connected compressor 109, and be depressurized, become the liquid refrigerant of low-temp low-pressure, arrive cooler 112.

Here, the liquid refrigerant of low-temp low-pressure carries out heat exchange with the cold air in each storeroom, the cryogen evaporation gasification in cooler 112.When evaporation gasification, obtain heat of gasification from surrounding, thus, in cooling chamber 110, generate the cold air for cooling down each storeroom.Use wind path 141 or throttle setting 141b(241), cold gas is branched to cold room 104, switch room 105, ice-making compartment 106, vegetable compartment 108, refrigerating chamber 107 from pressure fan 203, is cooled to respective target temperature district.Especially vegetable compartment 108, is operated by startup (ON)/stopping (OFF) of the distribution of cold air or heating unit (not shown) etc., it is possible to be adjusted between 2 DEG C to 7 DEG C, it is however generally that, most cases does not possess storehouse temperature detector unit.

With reference to Fig. 3, the flowing of the cold air circulated at each storeroom of freezer 100 is described.It is configured to: wind path 141 is passed through in the action that the cold air of each storeroom relies on pressure fan 203 to carry out, and returns cooling chamber 110.When returning the cold air come by cooler 112, carry out heat exchange, cooled, supplied to each storeroom by wind path.

First, carried out the cold air of heat exchange by cooling chamber 110, and be supplied to refrigerating chamber 107, switch room 105, ice-making compartment 106, and when throttle setting 141b opens, supply to cold room 104.It addition, passed through the cold air of throttle setting 141b, by from the wind path 141 towards vegetable compartment 108 towards wind path 141 branch in cold room 104, supply is to vegetable compartment 108.

Additionally, the cold air of each storeroom returns cooling chamber 110 again by wind path 141, by repeating this circulation, freezer is cooled to the temperature of regulation.

Here, it is circulated throughout the cold air of vegetable compartment 108, although returning cooling chamber 110 by suction inlet 126, but as shown in Figure 4, Figure 5, sprayer unit 131 is accommodated in outer housing case 127, being provided with moisture supply mouth 138 in outer housing case 127, this moisture supply mouth 138 is the peristome of the high humidity cold air for sucking vegetable compartment 108.The high humidity cold air being inhaled into is cooled down by the atomization portion 139 below dew point temperature, condensation, then nebulizes and is ejected.At this moment, during pressure fan 203 action, outer housing case 127 links with suction inlet 126, so mist is transported to cooling chamber 110 by suction inlet 126, wind path 141, supplies each storeroom to freezer 100.

It addition, inhalation mask 126a is connected with suction inlet 126, it is taken into the cold air of vegetable compartment 108 from peristome 147, by suction inlet 126, wind path 141, it is carried to cooling chamber 110.Here, in the present embodiment, outer housing case 127 is connected with inhalation mask 126a.Additionally, outer housing case 127 can be inhalation mask 126a by dual-purpose, it that case, moisture supply mouth 138 may also function as the effect of peristome 147.

In the cooling unit i.e. refrigerating chamber 107 of the front end being positioned at cooling pin 134,-15～the cold air of about-25 DEG C generated by cooler 112 by the operating of cooling system, utilize pressure fan 113 to flow, be cooled to such as 0～about-10 DEG C as the cooling pin 134 of heat conduction cooling-part.

At this moment, owing to cooling pin 134 is high conducting-heat elements, so it is cold and hot to be very easy to transmission, atomization portion 139 is also indirectly cooled to 0～about-10 DEG C via cooling pin 134.Here, the temperature of vegetable compartment 108 is 2 DEG C to 7 DEG C, and becomes the state comparing high humidity due to the evaporation from vegetable etc., if so atomization portion 139 becomes below dew point temperature, then can generate water in atomization portion 139, adhere to water droplet.

Additionally, it is not that atomization portion 139 is directly cooled down, but indirectly atomization portion 139 can be cooled down as the cooling pin 134 of heat conduction cooling-part by cooling, cooling pin 134 as heat conduction cooling-part has bigger thermal capacitance compared with atomization portion 139, it is thus possible to relax, atomization portion 139 is directly brought tremendous influence, atomization portion 139 can be cooled down, additionally, by realizing the effect of cold-storage, the dramatic temperature that can suppress atomization portion 139 changes, it is possible to realize the spraying that spray amount is stable.

Like this; comparative electrode 136 is possessed in the position relative with atomization portion 139; by having the voltage application portion 133 producing high-tension electricity potential difference between atomization portion 139 and comparative electrode 136; can stably set up the electric field near atomization portion 139; it is capable of micronized phenomenon; spray direction determines, it is possible to improve the precision of the fine mist being sprayed onto in outer housing case 127 further, using the teaching of the invention it is possible to provide the sprayer unit 131 that reliability is high.

And then, cooling pin 134 as heat conduction cooling-part is cooled down via thermal relaxation (thermalrelaxation) parts (thermal insulation barriers 152), so while atomization portion 139 is cooled down indirectly as described above by cooling pin 134, it also is able to further with the thermal insulation barriers 152 as thermal relaxation parts, indirectly cooled down by dual structure, it is possible to prevent atomization portion 139 from extremely being cooled down.

Sprayer unit 131 supplies mouth 138 from the moisture being arranged at outer housing case 127 and is taken into high humidity cold air, condenses in atomization portion 139 such that it is able to spraying.

The fine mist that atomizing electrode 135 produces is directed onto in outer housing case 127, and owing to being the least micropartical, so diffusibility is strong, fine mist also is able to be diffused into vegetable compartment 108 by moisture supply mouth 138.The fine mist of ejection, is produced by electrion, so can be with negative charge.On the other hand, in vegetable compartment 108, green green vegetable in the vegetable of in store green vegetable fruit etc. or fruit etc., these green vegetable fruit are easier to withered due to rising or during preserving transpiration.In vegetable in being stored in vegetable compartment or fruit, it will usually exist because the transpiration on the road bought or the transpiration in preserving and already at the vegetable of somewhat withered state or fruit, so with positive charge.Therefore, the mist being atomized is prone to concentrate on the surface of vegetable, thus freshness is improved.

Additionally, the fine mist of the Nano grade being attached to vegetable surface contains the ozone etc. of OH free radical and trace mostly, except having sterilization, antibacterial, degerming etc. effect, can also promote to utilize oxidation Decomposition except pesticide, and the increase of the nutrient of vitamin C content in vegetable etc. can be promoted based on antioxidation.

Here, when atomization portion 139 does not has water, separate arcing distance, the insulating barrier of cold air will not be destroyed, also will not cause electric discharge phenomena.Thus, between atomization portion 139 and comparative electrode 136, do not has electric current.This phenomenon is detected, it is possible to the high pressure of voltage application portion 133 is carried out start/stop control by the control unit 146 utilizing freezer 100.

Additionally, for the structure as above-mentioned embodiment and part that same technological thought can be suitable for, omit the description, but it is carried out by the structure at above-mentioned embodiment combines present embodiment, as long as no defect, i.e. can combination application.

Suction inlet 126 can be construed to the peristome connected with the storeroom (cold room 104, refrigerating chamber 107) being not provided with sprayer unit 131.

In present embodiment, private partition is formed by covering the outer housing case 127 of sprayer unit, and the interior space of outer housing case 127 connects with suction inlet, and cold air returns wind path 141 by this suction inlet from the vegetable compartment 108 as the storeroom possessing sprayer unit 131.

Sprayer unit 131 uses the dew generated by making moisture in air condense to spray, and is mainly made up of atomization portion 139, voltage application portion 133, cooling pin 134 as heat conduction cooling-part, outer housing case 127 is provided with moisture supply mouth 138.

Cooling pin 134 has extend to refrigerating chamber 107 side via the inside of thermal insulation barriers 152 protuberance 134a with making its front end convex.This protuberance 134a front end face and around do not possess thermal insulation barriers, become freezer indoor wall is extended to cold room 104 side by the inwall convex too of the resin forming of ABS etc..Owing to refrigerating chamber 107 is formed as the storeroom of drawer type, even if so this extension is in the case of opening door by internal accommodating container, also will not be easily seen by the user.

The flowing of the cold air circulated at each storeroom of freezer 100 is described with reference to Figure 34.The cold air of each storeroom relies on pressure fan 203 to work and by wind path 141, return cooling chamber 110.The cold air that return comes, when by cooler 112, carries out heat exchange and is cooled, be supplied to each storeroom by wind path.

First, the cold air carrying out heat exchange in cooling chamber 110 is supplied to refrigerating chamber 107, switch room 105, ice-making compartment 106, and when the throttle setting 241 possessed in flow to the discharge wind path 141a of cold room 104 from cooler 112 is opened, to cold room 104 cool-air feed.It addition, passed through the cold air of throttle setting 241, by with the discharge wind path 141a leading to vegetable compartment 108 towards wind path 141 branch in cold room 104, feed to vegetable compartment 108.

Additionally, the cold air after cooling down each storeroom is again by sucking wind path 141b, return cooling chamber 110, by this circulation is repeated, freezer is cooled to the temperature of regulation.

In vegetable compartment 108, the cold air of circulation is by as the suction inlet 126 towards the entrance sucking wind path 141b, return cooling chamber 110, but as shown in Figure 35, Figure 36, sprayer unit 131 is accommodated in the outer housing case 127 as private partition, is provided with the moisture as peristome for being taken into by the high humidity cold air of vegetable compartment 108 and supplies mouth 138 in outer housing case 127.

The high humidity cold air sucked, by the conduction of heat from cryogenic temperature district, is cooled down by the atomization portion 139 below dew point, condenses and be atomized.

Cold air as the cryogenic temperature district in the refrigerating chamber 107 to the cooling unit that cooling pin 134 cools down, the operating of cooling system is utilized to be generated by cooler 112,-15～the cold air of about-25 DEG C flowed by pressure fan 203, be cooled to such as 0～about-10 DEG C as the cooling pin 134 of heat conduction cooling-part.

Here, the temperature of vegetable compartment 108 is 2 DEG C to 7 DEG C, vegetable compartment 108 side of cooling pin 134 produces the temperature difference of more than 10 DEG C with the air of periphery, and due to from the evaporation of vegetable etc. so being to compare high humidity state, so atomization portion 139 becomes below dew point temperature, water can be generated in atomization portion 139, have water droplet to adhere to.

By voltage application portion 133, the atomization portion 139 being attached with water droplet being applied high voltage (such as 4～10kV), cause corona discharge, the water droplet of the front end of atomization portion 139 is granular, atomization by electrostatic energy.Further, due to liquid droplet charged, produced by Rayleigh division a few nm ranks with the nanoscale of electric charge or the fine mist of pico while, produce ozone and OH free radical etc..

Due to such spraying, the effect expected also can be different because of freezer distinctive use state.

Such as, it is diffused into the vegetable that the mist of vegetable compartment 108 mainly acts in freezer, while increasing the nutrient of vitamin C etc., it is also possible to expect that it has the effect preventing low temperature injury.

It addition, the bacterium that the mist diffusing to cold room 104 exists in mainly acting on freezer, its bacteria-eliminating efficacy can be expected.

So, it be necessary mistiness degree in Figure 38 by the effect in order to be expected in being apparent in storeroom, i.e. be replaced into the situation that the percent of decolourization of indigo carmine aqueous solution is indicated for mistiness degree necessary to the effect of vegetable and in order to manifest mistiness degree necessary to bacteria-eliminating efficacy to manifest it.

The ozone comprised in indigo carmine aqueous solution and mist or OH Free Radical, cause decoloring reaction, by measuring its percent of decolourization, carry out the quantification of mistiness degree.

Indigo carmine aqueous solution 10g is put into container (in present embodiment, the plastic culture dish of internal diameter 53mmm) in, container is arranged in cold room 104 and the vegetable compartment 108 measuring mistiness degree, after configuration starts 15 hours, take out container from cold room 104 and vegetable compartment 108, measured the absorbance of indigo carmine aqueous solution by ultraviolet-uisible spectrophotometer (Japan Spectroscopy Corporation's system: UV-245).

It is placed with the container of indigo carmine aqueous solution, the central part of 3 shelfs being arranged respectively in cold room 104, and place with the open state of not lid, in vegetable compartment 108, before and after accommodating container 119, left and right is distributed 6 containers, and the cassette (not shown) on the top being positioned at accommodating container 119 is respectively configured 6 containers with the open state of not lid too.Here, percent of decolourization is defined as the absorbance with blank indigo carmine aqueous solution except value obtained by the variable quantity of the absorbance of the indigo carmine aqueous solution of the blank (Blank) being configured without in freezer.

Additionally, the container of indigo carmine aqueous solution being placed with blank is also disposed in having the place of identical humiture environment with cold room 104 and vegetable compartment 108.

The percent of decolourization of cold room 104 is the meansigma methods of the measurement result of 3 containers, and the percent of decolourization of vegetable compartment 108 is the meansigma methods of the measurement result of 12 containers.

Additionally, in order to prevent indigo carmine aqueous solution from decolouring because of the reason beyond mist, preferably do one's utmost to avoid contact with light.

As shown in figure 42, manifest percent of decolourization necessary to bacteria-eliminating efficacy, bigger than manifesting for percent of decolourization necessary to the effect of vegetable, in the absorbance measurement of the indigo carmine aqueous solution in the freezer 100 of present embodiment, result is, vegetable compartment 108, cold room 104 the respective percent of decolourization numerical value than Figure 42 big, and the percent of decolourization in cold room 104 is higher than the percent of decolourization in vegetable compartment 108.

That is, the mistiness degree of cold room 104 is higher than the mistiness degree of vegetable compartment 108.

In addition, in the freezer of the vegetable compartment 108 being provided with sprayer unit 131, environment is about 5 DEG C, relative humidity is from about 70% to 90%, if being scaled absolute humidity, being then 4.77～6.14g/m3, in the freezer of cold room 104, environment is about 5 DEG C, and relative humidity is from about 10% to 20%, if being scaled absolute humidity, then it is 0.68～1.36g/m3.

The reason that the absolute humidity of vegetable compartment 108 is bigger than the absolute humidity of cold room 104 is, cause because being accommodated in the evaporation of the vegetable of vegetable compartment 108, owing to cold room 104 being typically all accommodated with packaged food, so the absolute humidity in freezer is big as vegetable compartment 108 hardly.

By above experiment it will be appreciated that in order to manifest bacteria-eliminating efficacy, need denseer with the mistiness degree manifesting low temperature injury inhibition than manifesting the nutrient increase effect as the effect for vegetable.

Therefore, in present embodiment, being formed with mist feed path, in this mist feed path, as the cold room 104 of the storeroom mainly for manifesting bacteria-eliminating efficacy, compared with the vegetable compartment 108 as the storeroom mainly for manifesting the effect for vegetable, concentration is richer.

Specifically, on the basis of the mist of ejection is full of in private partition, according to producing forced convertion in above-mentioned private partition, or by free convection, mist feed path produces change, switches to and feed to vegetable compartment 108, or feed to other storeroom.

In present embodiment, mist feed path possesses pressure fan 203, be configured to the structure by switching the mist feed path supplying mist with or without the work of pressure fan 203.

Specifically, do not had the flowing of compulsory cold air in the situation of pressure fan 203 stopping, i.e. private partition by free convection in the case of, the mist being full of in private partition feeds in vegetable compartment 108 via peristome 147.Additionally, when pressure fan 203 works, the flowing of cold air based on forced convertion is produced in private partition, owing to outer housing case 127 is connected with suction inlet 126, so mist is carried to cooling chamber 110 by suction inlet 126, wind path 141, and discharging the cold airflow of wind path 141a flowing by via cooling chamber, mist is fed into cold room 104.

That is, the cold air cooled down by vaporizer 120, by double air doors 128 control its enter, be not always cold room 102, vegetable compartment 104 path in circulate.It addition, when freezer 100 entirety is the coldest, the rotation of pressure fan 121 stops, and the circulation of cold air also stops.At this moment, cooling circulation i.e. compressor 114 also stops.

Below, the flowing of the cold air of circulation in cold room 102 represented in Figure 44 and Figure 45 is described.

The cold air cooled down by vaporizer 120, as desired by being referred to as the cold room discharge pipe 129a of wind path or pipeline, via the outlet 130 at cold room 102 upper opening, is discharged to cold room 102.Additionally, the cold air discharged from outlet 130, the mist as atomising device 200 discharge of the 1st odor removal possessed with the upstream portion of the wind path in cold room 102 is met, and is diffused into cold room 102 overall.

Comprise the cold air of the mist having passed through cold room 102, be inhaled into the recovery port 131 in cold room 102 lower openings.Then, it is inhaled into the cold air comprising mist of recovery port 131, by the 2nd odor removal possessed in the backwind tube 129b as pipeline in the downstream of cold room 102, i.e. catalyst type odor removal 135, then being ejected into vegetable compartment 104, it is overall that mist is diffused into vegetable compartment.Finally, passed through the cold air comprising mist of vegetable compartment 104, again returned to vaporizer 120.

So, the 1st odor removal is the odor removal of diffusion type based on the mist comprising OH free radical.Although the most several seconds of the life-span of OH free radical itself, extremely short, but surrounded about by mist, OH free radical is discharged while the dissipation of the mist of 6～10 minutes, can significantly extend its life-span, fill the air to storeroom after entirety at mist, fog dissipation, so each position in storeroom, deodorizing effect based on OH free radical can be played.

As shown in the embodiment, 1st odor removal is the odor removal of the diffusion type being carried out deodorization by the material diffusion making deodorizing effect high, 2nd odor removal is different deodorization mode, by utilizing the catalyst cold air to being passed through to carry out the catalyst type odor removal of deodorization.So, it is the odor removal of different modes by making the 1st odor removal and the 2nd odor removal, it is possible to different stinks is carried out deodorization.

And then, as shown in the embodiment, the upstream side of the wind path in storeroom, the odor removal of configuration diffusion type, catalyst type odor removal is possessed in downstream, thus utilize the material that the deodorizing effect spread by the odor removal of diffusion type is high (in present embodiment, it is contained within the mist of OH free radical), it also is able to carry out the deodorization of catalyst type odor removal itself, foul smell owing to being adsorbed by OH radical pair catalyst type odor removal further carries out eliminating stink, it is possible to play based on the collaborative effect possessing two odor removals.

In addition, in the present embodiment, as odor removal, possesses the atomising device carrying out spraying, but in the structure possessing the electrostatic atomization apparatus identical with present embodiment, do not possess cooling pin 534 and in the case of discharging, electrostatic atomization apparatus becomes and do not sprays the mist as liquid, and become and can produce the ozone as gas and the odor removal of anion.

But, these utilize the odor removal of ozone and anion, it it is air deodorization, be not present embodiment based on the deodorization being included liquid fine as OH free radical by mist, so the adhesive force for wall or food is the most weak, and the material discharged is gas, so the durability of its time i.e. life-span is the shortest, therefore, it can be said that be the eliminating malodours from gases device concentrated and smaller space is carried out deodorization.

It addition, in the case of not carrying out spraying and utilizing electrostatic atomization apparatus as ozone generating-device or negative ion generating device, it is possible to displacement is set to the device of other forms of ozone generating-device.In this case, need not cool down pin, certainly also without to cooling pin cooling, so the arbitrary position can certainly being arranged in freezer as the electrostatic atomization apparatus of antibiotic device, even and if in the case of possessing cooling pin, cooling pin is not used as atomizing electrode, but be also effective for the location of atomising device, in this case, may be mounted at the most arbitrary freezer inwall, in the case of being installed on thermal wall, at least can be installed on freezer inwall with high accuracy, identical atomising device can be jointly utilized with the freezer carrying out spraying.

Below, the feature structure portion to the freezer of the present invention, i.e. the catalyst type odor removal 135 maintaining catalyst as the 1st odor removal illustrate with the effect of electrostatic atomization apparatus 200, the effect as atomising device.

As the abnormal smells from the patient produced from the food being stored in cold room, main flow is the nitrogen class of the sulfur class of methanthiol etc., trimethylamine, dimethyl sulfide (dimethylsulfide), dimethyl disulfide (Dimethyldisulfide) etc., and catalyst can adsorb and remove these abnormal smells from the patients.

The catalyst type odor removal 135 keeping catalyst is arranged at the downstream of the cold room of the storeroom the highest as temperature, will adsorb in the position close to generation source from the raw substantial amounts of abnormal smells from the patient of produce that stores being in cold room, it is possible to cold air is carried out deodorization.Therefore, it is possible to prevent the substantial amounts of abnormal smells from the patient produced at cold room to be recycled to other storeroom together with cold air.

On the other hand, from the mist of electrostatic atomization apparatus 200 ejection, the OH free radical strong containing oxidability or ozone, even if only mist also is able to decompose odour component.Therefore, odour component direct oxidation is decomposed by the mist being diffused into together with cold air in the space of storeroom, it is possible to the space Direct Resolution deodorization to storeroom.

It addition, about stink, if the ozone concentration in home-use freezer reaches more than 30ppb, then people may feel that ozone abnormal smells from the patient, causes sense of discomfort, so need to control at below 30ppb ozone concentration.On the other hand, mist amount is controlled according to the mode that amount is 10～50 μm ol/L of the free radical produced with ozone simultaneously.

Additionally, the ozone produced when utilizing the spraying of electrostatic atomization apparatus 200, due to the heavier-than-air characteristic of ozone, lower side can be moved to, so the catalyst type odor removal 135 that can be effectively possessed to the position on the lower of the ratio centrage on the above-below direction of cold room flows, thus by ozone, the catalyst type odor removal 135 adsorbing stink substance is persistently carried out deodorization, so catalyst type odor removal 135 can always be to maintain the state being updated, the reduction of suppression deodorizing capability.

Figure 46 is the figure comprising catalyst and the deodoriging properties of the mist of OH free radical representing embodiment of the present invention 12.

Experimental condition is as described below, and BOX capacity is about 400L, and in BOX, temperature sets and is about 20 DEG C, and with electrostatic atomization apparatus 200, the freezer pipeline being provided with the catalyst type odor removal 135 keeping catalyst is arranged in BOX (mist+catalyst).Using initial concentration be 10ppm, put into BOX as the dimethyl disulfide (below, DMDS) of representational stink, the air quantity of the wind speed about 0.6m/s that flows in pipeline, the DMDS concentration measuring per stipulated time by GSMS, calculate DMDS survival rate.And, as comparison, for eliminating the structure (blank situation) of catalyst and electrostatic atomization apparatus 200 or being only provided with the structure (the only situation of catalyst) of the catalyst type odor removal 135 keeping catalyst, be only provided with the structure (the only situation of mist) of electrostatic atomization apparatus 200, carry out identical test.

As shown in figure 46, can confirm that following situation: relative to blank situation, the situation of a catalyst, the situation of a mist, the DMDS survival rate of catalyst+mist is minimum, deodoriging properties is good, compared with the situation of only catalyst or only mist, by combination catalyst and mist, it is possible to increase deodoriging properties.

It addition, in deodorization catalyst, it is preferred to use play the catalyst with metal-oxide of synergy by using with nanoparticle simultaneously.This is because, contacted with the metal-oxide on catalyst surface by the ozone produced with nanoparticle simultaneously, generate the free radical that activity is big, this free radical is adsorbed in deodorization catalyst or acts on the malodorous elements of neighbouring existence, thus compared with the situation using deodorization catalyst and nanoparticle respectively, it is possible to increase deodoriging properties.

So, the preferred metal-oxide of catalyst.In the present embodiment, it is the cellular activated carbon that have employed by being formed by manganese catalyst and the odor removal filter formed, but specifically, is Mn-Cu based composite oxide (manganese dioxide (MnO₂), copper oxide (CuO)), for metal, even platinum gold, silver, palladium and the titanium oxide as metal-oxide also are able to expect same effect.

Comprise the mist of OH free radical in cellular catalyst, it is possible to make the cold air containing odour component with the mist comprising OH free radical or ozone in a large number by these metal-oxides.

In addition, in present embodiment, as cellular shape, can be the catalyst of the lamellar that can be attached to the wall in such as wind path, in this case, although owing to the contact area with the cold air in wind path reduces, deodoriging properties is caused to reduce, but owing to the wind path resistance of cold air reduces, during for paying attention to saving the energy, it is effective method.

Additionally, for shape, than that described above, it is also possible to be fibrous keeping method, just can be suitable for so long as not the situation contrary with the purpose of the present invention.

It addition, in present embodiment, employ activated carbon as adsorbent, but even Na type hydrophobic zeolite (SiO₂、Al₂O₃) also be able to expect same effect.

Additionally, although the adsorbance that catalyst is originally is limited, but contacted in a large number with the catalyst formed by manganese class by the mist containing OH free radical, the effect of OH free radical can be relied on, the odour component being adsorbed in catalyst is aoxidized, decomposes, removes, therefore, it is possible to extend the life-span of catalyst such that it is able to keep deodorizing effect for a long time, more efficiently carry out deodorization, degerming.

As mentioned above, in the present embodiment, the mist comprising the OH free radical with degerming, deodorizing effect spreads in storeroom, to carrying out Direct Resolution deodorization in space, and then, the mist contact containing OH free radical has the catalyst of deodorizing effect, thus is adsorbed the odour component being attached to catalyst, deodorizing effect can be improved, effectively the air in storeroom and these both sides of cold air circulated all are carried out degerming, deodorization.

(embodiment 13)

Figure 47 is the longitudinal section of the freezer storeroom in embodiments of the present invention 13, Figure 48 is the skeleton diagram of the circulation wind path of the cold air of the freezer in embodiments of the present invention 13, Figure 49 is the enlarged drawing in the A portion of Figure 46, and Figure 50 is the figure of the sense evaluation result of the deodorization power representing the odor removal in embodiments of the present invention 13.

Additionally, for the structure as above-mentioned embodiment and part that same technological thought can be suitable for, omit the description, but it is carried out by the structure at above-mentioned embodiment combines present embodiment, as long as no defect, i.e. can combination application.

As the atomising device 200 of the atomising device producing mist, it is arranged in the private partition 140 arranged on the top of vegetable compartment 104, comprises the mist of the OH free radical produced from electrostatic atomization apparatus 200, accumulate in private partition 140 with the state of high concentration.Although private partition 140 is disposed on the space in freezer 100, but is the structure that can not preserve food, become the only accumulation structure from the mist of electrostatic atomization apparatus 200 supply.

Below, for the freezer of said structure, its action, effect are described.

As the electrostatic atomization apparatus 200 of the 1st odor removal, controlled in the way of often to accumulate the mist of high concentration to private partition 140, so there is the mist of high concentration in private partition 140 accumulation.Therefore, the cold air after cooling vegetable compartment 104, when by private partition 140, return cooling chamber 115 with the mist of the high concentration of accumulation simultaneously, but the space in cooling chamber 115 is bigger, so there will be the state that mist is thinning than private partition 140.And then, relying on cooling circulation, the cold air cooled down by vaporizer 120 is by pressure fan 121 again when each storeroom circulates, and thinning mist also circulates to cold room 102, switch room 106, ice-making compartment 105, vegetable compartment 104, refrigerating chamber 103 simultaneously.

Below, the flowing of the cold air of circulation in the cold room 102 shown in Figure 47 and Figure 48 is described.

The cold air cooled down by vaporizer 120, as desired by being referred to as the cold room discharge pipe 129a of wind path or pipeline, via the outlet 130 at cold room 102 upper opening, is discharged to cold room 102.

By mist produced by the atomising device 200 as the 1st odor removal possessed in vegetable compartment 104, by the flowing of cold air, discharge to wind path from vegetable compartment 104, via cooling chamber 115, by cold room discharge pipe 129a, thus to the overall diffusion of cold room 102 together with the cold air being circulated.

So, in the present embodiment, in the private partition 140 in the space of the upstream side as cold room 102, possesses the 1st odor removal.

Comprise the cold air of the mist having passed through cold room 102, be inhaled into the recovery port 131 in cold room 102 lower openings.Then, being inhaled into the cold air comprising mist of recovery port 131, by the 2nd odor removal possessed at the backwind tube 129b of the wind path in the downstream as cold room 102, i.e. catalyst type odor removal 135, be then exhausted from vegetable compartment 104, it is overall that mist is diffused into vegetable compartment.Finally, passed through the cold air comprising mist of vegetable compartment 104, again returned to vaporizer 120.

For deodorizing effects based on these odor removals, due to identical with embodiment 12, so detailed.

Figure 48 is to represent the figure comprising catalyst with the functional evaluation of the deodorization power of the mist of OH free radical, is to carry out, by actual freezer, the result that deodorizing test obtains.

6 kinds of food materials (sardine, dumpling, natto, Potato salad, Bulbus Allii Cepae, pickled radish) of the food materials stronger as the abnormal smells from the patient being generally held in cold room are put in the container that open hole, preserve two days in cold room, take out food materials, take the gas of the cold room after 1 day, implement functional evaluation.

By 6 stinks, evaluation judges that personnel are carried out according to 6 grades of stink explicit representations.0 represents odorless, and 1 represents the most light stink, and 2 represent the stink that can easily feel, 3 represent the stink being clearly felt that, 4 represent strong stink, and 5 represent the stink that intolerable impression is strong.

Result is for odor strength, and blank situation is 2.8, and the only situation of catalyst is 1.6, and the situation that simultaneously there is catalyst and nanoparticle is 1.0, it is possible to being identified through catalyst can be to carrying out deodorization in cold room with nanoparticle.

As mentioned above, in present embodiment 13, by depositing private partition 140 in sucking wind path 142a in vegetable compartment, the mist produced from electrostatic atomization apparatus 200 utilizes freeze cycle to be efficiently suctioned cooling chamber, therefore, can spread to each storeroom, so by the mist comprising OH free radical, it is possible to the odour component of the air in the freezer of each storeroom is carried out Direct Resolution deodorization.

In other words, by deodorization catalyst being arranged in the downstream pipeline of cold room, nanoparticle passes through deodorization catalyst, will not cut down, but can overall in cold room spread, and then, by arranging deodorization catalyst at the pipeline being easiest to produce the cold room downstream of stink, effectively abnormal smells from the patient can be adsorbed, decompose, become the structure that stink is difficult to circulate to other rooms.

And then, the odor removal of the honeycomb shape of catalyst will be kept according to having angle relative to the flowing of cold air and the mode that contacts therewith is arranged, on the basis of the contact area increasing cold air, it is possible to reduce flowing resistance.At this moment, it is preferable that odor removal is obtuse angle relative to the angle, θ of cold air.

It addition, according to the result confirmed by the experiment of the structure of present embodiment, it is known that in order to reduce flowing resistance, the scope of preferably more than 110 degree, and in order to ensure deodoriging properties, the scope of preferably less than 130 degree.

And then, comprise the mist of OH free radical, it is possible to reach catalyst by cold air, so the mist contact comprising OH free radical has the catalyst of deodorizing effect, it is thus possible to improve the effect of catalyst, effectively the air in storeroom is carried out degerming, deodorization with this two side of cold air in circulation.

Here, in present embodiment 13, although private partition 140 is arranged on vegetable compartment and sucks in wind path 142a, but be not limited to this, be disposed near vegetable compartment suction inlet (not shown) also being able to play the same role.

And then, if private partition 140 is provided with peristome towards above-mentioned storeroom, then vegetable compartment 104 can be directly fed mist, it is possible to be consumed, more preferably when preventing mist through cooling chamber 115 or discharge wind path 130.

And then, compressor 114 is operated by freeze cycle, and vaporizer 120 is cooled down, and when cold air relies on pressure fan 121 to circulate, needs to make mist fill the air in whole indoor of freezer, it is advantageous to making the mist amount produced from sprayer unit is maximum.
