The refrigerator of the type that in this embodiment, opens and closes in addition, with the track of case in the relevant item of major part of the invention of the following stated also goes for framework that existing general passing through be installed on door and is located at.
Below just as above-mentioned the refrigerator of formation to its action, act on and describing.
In current refrigerator; Satisfy no matter round the clock and the temperature that the temperature of decision is set control, but night, and the temperature of refrigerator surrounding environment reduces; Thermic load reduces; In addition, the thermic load of taking out or producing when changing food is extremely little, so the in-cabinet temperature of refrigerator becomes and have a few cold temperature setting a little.In addition, even the existing power saving unit that uses optical sensor plays a role it if do not push the dedicated button that records " energy-saving mode " etc. wittingly through the user, can not obtain energy-saving effect.In addition; Even make wittingly under the situation that energy-saving mode plays a role the user; Because the user must carry out push-botton operation wittingly when removing this energy-saving mode, therefore forgotten to remove and design temperature still state is constant when uprising, the preservation state of food might variation.
The present invention propose a kind of need not to push dedicated button and have automatic function promptly automatically realize energy-conservation refrigerator.That is, the illuminance transducer 36 of the front through being installed on refrigerator 100 detects the illumination level around the refrigerator that the irradiation by sunshine or room lighting equipment produces.
So with detected illumination level Input Control Element, if lasting littler than the setting that is predetermined, being judged as so is night or nobody's activity, automatically the cooling performance with refrigerator switches to the energy-saving mode that reduces slightly.
And, when illumination level is bigger than setting or before can predicting the certain hour that has initial door switching, making running return normal mode.But; For the detection that will be caused by the illumination from luminous for example automobile of the moment outside the room etc. etc. forecloses; In order to prevent to recover (resetting) because of external disturbance causes energy-saving mode; Only under the situation that the illumination level of certain time is kept, just removing this function of energy-saving mode as anti-external disturbance unit setting, also is effective when realization is more energy-conservation in actual use.
So; Using illuminance transducer 36 as detecting under the situation of detecting unit of variation that refrigerator is provided with environment; Because it is dark can detecting the periphery that refrigerator is set and be bright, therefore can differentiate the person's of being to use activity possibility high daytime or night substantially.
In addition, when the kitchen that refrigerator is set etc. is when not having the space of window, owing to consider user's the activity time band and the basic interlock of irradiation of room lighting equipment, so can not realize energy-conservation more lavishly.
Thus; In user's activity time; Energy-saving mode is disengaged and is usually cooling off under the refrigerating mode, and indirect detection the situation of a switching occurs and cools off fully to being easy to, even therefore under the situation that the door switching occurs, also can keep the fresh-keeping property of food.
If compare with the refrigerator of existing manual setting energy-saving mode; So when the user does not carry out push-botton operation wittingly; Becoming higher and when still occurring door under the constant state that does not fully cool off of state and opening and closing when design temperature under the energy-saving mode that is not disengaged; Especially food temperature sharply rises because of in-cabinet temperature, and preservation state can variation.But in the present invention; In user's activity time; Energy-saving mode is disengaged and is cooling off under the refrigerating mode usually; Because indirect detection is to the situation that is easy to occur a switching and cool off fully in advance, even therefore under the situation that the door switching occurs, also can keep the fresh-keeping property of food.
In addition; Also imagination for example is positioned at window many sunshines during good place when the kitchen; Even perhaps also will carry out the situation such as irradiation of room lighting equipment during night for some reason; As detecting variation that refrigerator is provided with environment to get into the detecting unit of energy saver mode, except illuminance transducer 36, the behaviour in service detecting unit that preferred setting can the actual behaviour in service of indirect detection refrigerator.
As the behaviour in service detecting unit of behaviour in service that can this refrigerator of indirect detection, can consider: the in-cabinet temperature sensor 53 of the in-cabinet temperature checkout gear that the conduct that refrigerator doors opens and closes condition detection apparatus (door SW), detect each storeroom temperature of refrigerator detects in-cabinet temperature, detect the refrigerator design temperature the design temperature checkout gear, detect the external air temperature sensor 52 of refrigerator external air temperature.
Using refrigerator doors to open and close under the situation of condition detection apparatus (door SW) as the behaviour in service detecting unit; To open and close the testing result Input Control Element of condition detection apparatus as the door of behaviour in service detecting unit; In the certain hour that is predetermined, do not have under the situation of a switching; Be judged as nobody's activity, automatically the cooling performance with refrigerator switches to the energy-saving mode that reduces slightly.
In addition; Under the situation of in-cabinet temperature sensor 53 as the behaviour in service detecting unit of the in-cabinet temperature checkout gear that the conduct that the temperature of using each storeroom of refrigerator detects detects in-cabinet temperature; Will be as the testing result Input Control Element of the in-cabinet temperature checkout gear of behaviour in service detecting unit; Under the situation that does not rise to the in-cabinet temperature more than the certain value that is predetermined; Can detect indirectly and not get into heating installation because door opens and closes, and be judged as nobody's activity, automatically the cooling performance with refrigerator switches to the energy-saving mode that reduces slightly.
In addition; Using under the situation of in-cabinet temperature checkout gear that in-cabinet temperature is detected that detects each storeroom temperature of refrigerator as the behaviour in service detecting unit; Under the situation that does not have the temperature change more than the certain amplitude; Be judged as except nobody's activity, also be in the stable normality of the less and variations in temperature that also not have to cause because of thawing etc. of the variations in temperature of refrigerator surrounding enviroment, automatically the cooling performance with refrigerator switches to the energy-saving mode of reduction slightly.
Under the design temperature checkout gear of the design temperature that use to detect refrigerator situation as behaviour in service detecting unit that can indirect detection refrigerator behaviour in service; Be to want under the situation of design temperature for the refrigerating mode of " by force " of cold storage chamber energetically for example in user intention; Even for example when the condition that gets into energy-saving mode according to illuminance transducer 36 or force-feeling sensor 40 as first detecting unit is set up, also can realize meeting the cooling of user's intention through the control that does not get into energy-saving mode.
So use illuminance transducer 36 and behaviour in service detecting unit as detecting unit; Environment is set with behaviour in service gets into energy-saving mode through what confirm refrigerator, can provides a kind of and on reality is used, can not diminish user's ease of use and realize effective more energy-conservation refrigerator.
In addition; Except carrying out this automatic energy-saving mode, next the memory cell of the output signal through possessing storage illuminance transducer 36 and behaviour in service detecting unit is further carried out describing for the invention of the energy-saving mode of the user mode customization of each family as detecting unit.
Pass through the information during the accumulation necessarily in the memory cell 55 of the output signal of storing illuminance transducer 36 and behaviour in service detecting unit as detecting unit; Decide the economize on electricity running of a certain cover half formula, automatically suppress or the compressor 109, cooling fan 113, the temperature-compensating that stop as the electric load parts are turned round with the economize on electricity of the action of heater 56, cabinet intraoral illumination 57 etc.
Promptly; Through the detection information during memory cell 55 accumulation necessarily; According to the life pattern of this its family of information prediction, when the activity of this family of prediction for going to bed or when not existing, can carrying out the inhibition of cold inhibition or compressor revolution; Make the running of other electric load parts such as heater be suitable for this family, can further realize energy-conservation.
Particularly; Be provided with at the refrigerator that obtains by detecting unit of storage under the situation of information of environmental change; The illumination level in past, force-feeling sensor's 40 detection level (1evel) cut apart with certain time unit be stored in the memory cell; It is carried out pattern discrimination; For the time band of differentiating in one day activity time for certain hour nobody's activity,, also automatically the cooling performance of refrigerator is switched to the energy-saving mode of reduction slightly even under the illumination level of reality or force-feeling sensor's 40 detection level condition with higher.
But preferred control module possesses following debugging functions; Promptly; In that the detecting unit of environmental change is set is relevant with detecting refrigerator, get under the situation of energy-saving mode according to the differentiation of memory cell, pass through certain hour then under the illumination level of reality or force-feeling sensor's 40 detection level condition with higher; Remove energy-saving mode and return the debugging functions of normal mode; Through possessing this debugging functions,, also can keep the cooling performance of refrigerator even under the situation of the life that departs from common life pattern.
In addition, the testing result (information) of the behaviour in service detecting unit that storage can indirect detection refrigerator behaviour in service is the direct and effective means of carrying out through the life pattern of predicting this family.
Particularly; When using refrigerator doors to open and close condition detecting unit (door SW) as the behaviour in service detecting unit; To open and close the testing result Input Control Element of condition detection apparatus as the door of behaviour in service detecting unit; And it is divided into certain time unit is stored in the memory cell; For differentiate for door in one day activity time open and close do not exist or less promptly differentiate be time band less than the setting that is predetermined, automatically the cooling performance of refrigerator is switched to the energy-saving mode that reduces slightly when being in this during band time.
In addition; Likewise under the situation of in-cabinet temperature sensor 53 as the behaviour in service detecting unit of the in-cabinet temperature checkout gear that the conduct of using each storeroom temperature of detection refrigerator detects in-cabinet temperature; Detect the temperature of each storeroom by in-cabinet temperature sensor 53; To whether be cooled to and be divided into certain time unit below the set point of temperature and be stored in the memory cell; For differentiate for storeroom in one day activity time by the time of fully cooling band, automatically the cooling performance of refrigerator is switched to the energy-saving mode that reduces slightly when being in this during band time.
So, with the illumination in past, door open and close, in-cabinet temperature is cut apart with certain time unit and be stored in the memory cell, through it is carried out the running that pattern discrimination is controlled refrigerator.
As above-mentioned; When switching to the energy-saving mode of the running of economizing on electricity, automatically reduce the cooling performance of refrigerator slightly, promptly reduce the revolution of compressor; The revolution etc. that perhaps reduces cooling fan 113 reduces amount of cooling water, makes in-cabinet temperature several degrees centigrade (for example 1 ℃) that rises when carrying out slow cooling.
When carrying out this economize on electricity running, supply to the mist high concentration that will produce mist jet private space 150 by the electrostatic atomization apparatus 131 that the vegetable compartment that is set to the maximum temperature band 108 is possessed.
The vegetable compartment 108 that possesses mist jet private space 150 is cooled off through the cold air that the device 112 that is cooled cools off.The cold air of cooling vegetable compartment 108 is blowed by cooling fan 113; Arrive baffle plate 130 through discharging wind path 141; When the state that baffle plate 130 is opened, cold air is discharged the vegetable compartment of shunting in wind path 141 ways and is discharged wind path 141a from vegetable compartment outlet 143 inflow vegetable compartment 108 through associating.Flow into the peripheral circulation of the cold air of vegetable compartment 108, hypomere accommodating container 119 is cooled off at hypomere accommodating container 119.And cold air sucks wind path 142a through vegetable compartment, sucks the mist jet private space 150 that possesses in the wind path 142a via vegetable compartment and returns once more with cooling chamber 110.
Electrostatic atomization apparatus 131 is controlled as when economizing on electricity running the mist of high concentration is put aside at mist jet private space 150, and the mist savings of high concentration is in mist jet private space 150 between the economize on electricity on-stream period.Therefore, the cold air of cooling vegetable compartment 108 returns cooling chamber 110 with the mist of the high concentration of being put aside when the mist jet private space 150 simultaneously.Because the space of cooling chamber is bigger than mist jet private space 150, so mist is in thin state (state that the concentration of mist reduces).And through cool cycles, once more to each storeroom circulation time, thin mist is also simultaneously to refrigerating chamber 104, switching chamber 105, ice-making compartment 106, refrigerating chamber 107 circulations through cooling fan 113 for the cold air of device 112 coolings that are cooled.In addition, because mist jet private space 150 is provided with peristome towards above-mentioned vegetable compartment 108, therefore can directly supply with mist to vegetable compartment 108.
So; Can carry out degerming through supplying with the mist that comprises the correction compositions of worrying to rising that breeding generated such as assorted bacterium energetically because of the refrigerator in-cabinet temperature; In addition; Because it is can mist thin in the cooling chamber 110 be supplied to refrigerating chamber 104, therefore also no problem at aspects such as smell such as ozone flavor or material degradation.Thus, can supply with mist with power save mode.
At this moment, in fact the ozone concentration of refrigerating chamber 104 and vegetable compartment 108 is measured, the ozone concentration of vegetable compartment 108 on average is about 20ppb as a result, and the ozone concentration of refrigerating chamber 104 on average is about 10ppb, and it is suitable therefore being confirmed to be.And, confirm that also the ozone concentration of cooling chamber 110 on average is about 100ppb.
Ozone concentration is that 10ppb has 99% degerming rate when above, and 30ppb is that ozone is allowed threshold, in addition; Confirm and to know from the situation of the big induced damage resistive that 80ppb caused to vegetables through prior BOX test; Because the ozone concentration of refrigerating chamber 104 and vegetable compartment 108 is 10ppb to 20ppb, therefore in this embodiment 1, through the effect of mist; Refrigerating chamber 104 can obtain bacteria-eliminating efficacy, and vegetable compartment 108 can obtain bacteria-eliminating efficacy and but can not cause damage to vegetables.
And; The ozone concentration that also can know cooling chamber 110 is about 100ppb and is the ozone concentration that can obtain sufficient bacteria-eliminating efficacy; Therefore can know not only refrigerating chamber 104, vegetable compartment 108; Also by degerming fully, therefore can carry out the degerming of full chamber through the cold air of discharging wind path 141 and being discharged to refrigerating chamber 107, ice-making compartment 106, switching chamber 105.
As above; In this embodiment 1; Comprise: possess through partition wall and produce electrostatic atomization apparatus by the refrigerator main body of a plurality of storerooms of heat insulation division, in above-mentioned refrigerating chamber as the mist of the fresh-keeping composition that contains hydroxy or ozone composition; Also comprise: can detect the refrigerator behaviour in service detecting unit, according to above-mentioned detection to the output signal suppress or stop the control module of economize on electricity running of the action of refrigerator electric load parts; Under the situation of carrying out above-mentioned economize on electricity running; Through above-mentioned fresh-keeping composition generation unit above-mentioned refrigerating chamber is supplied with fresh-keeping composition; Even make under the situation that in-cabinet temperature rises in when running economize on electricity, the mist that is produced by electrostatic atomization apparatus 131 also energy efficiency is inhaled into cooling chamber through freeze cycle well, and is diffused into each storeroom from cooling chamber; Therefore can suppress the microorganisms such as mould or bacterium yeast and virus that wall, air, vegetable surface in the cabinet of each storeroom adhere to through the mist that contains hydroxy increases, and can decompose odor pollutant, keep fresh-keeping property.
In addition, in this embodiment 1, mist jet private space 150 is located at vegetable compartment sucks in the wind path 142a, but be not limited to this, also can serve the same role near being arranged on vegetable compartment suction inlet 144.
And mist jet private space 150 possesses the peristome that is communicated with above-mentioned storeroom (vegetable compartment 108), can directly supply with mist to vegetable compartment 108 thus, and mist is consumed in the time of therefore can preventing via cooling chamber 110, discharge wind path 141, thus more preferably.
And; When cooling off the state that stops because of freeze cycle; The generation that suppresses mist with mode from mist to vegetable compartment 108 that can only supply with is preferred, and this is can not caused damage by hydroxy because of the mist of high concentration because be kept at the vegetables or the fruit of vegetable compartment 108.
Maintain ozone, hydroxy etc. in the mist by electrostatic atomization apparatus 131 generations, it has strong oxidizing force.Because the part of bacterial cell memebrane protein is decomposed and bacteriolyze bacterium deactivation as a result by these ozone, free-radical oxidation in the bacterium tissue.
So; In preserving the refrigerator cabinet of food, carry out when antibiotic; Because expectation suppresses infringement of vegetables and attack bacteria only; Therefore promote finally that through destroying bacterial cell membrane the ozone of the degree that the deactivation of bacterium is promptly died or the amount of hydroxyl free radical are preferred, rather than powerfully make the ozone that bacterium dies from body or the amount of hydroxyl free radical to moment.That is to say that the deactivation of in the scope that above-mentioned fresh-keeping of vegetables property is not had influence, carrying out bacterium is effective.Therefore, the mist of generation can be in the vegetable compartment, when vegetable surface carries out antibiotic, degerming, sterilization, the harmful substance of can the oxidation Decomposition vegetable surface adhering to.
Thus; So even carry out because be in a plurality of storerooms in the higher storeroom cabinet of temperature, under the situation of economize on electricity running that possibility that microorganisms such as mould or bacterium yeast and virus that vegetable surface adheres to increase is high; Also can increase and keep the running of economizing on electricity automatically on the basis of fresh-keeping property suppressing microorganisms such as these bacterium yeast and virus; In real-world operation, can on the basis of keeping fresh-keeping property, realize more energy-conservation.
Fig. 6 is illustrated among the BOX that is envisioned for refrigerator vegetable chamber the result who confirms as the bacteria-eliminating efficacy of the coliform of the representative bacterial classification of bacterium.
Experimental condition is being set at: the about 70L of BOX capacity; Temperature is about 5 ℃ in the BOX; Relative humidity is more than the 90%R.H in the BOX, and the electrostatic atomization apparatus 131 of this embodiment 1 is located in the BOX and is made it to connect running rate running that (OFF) minute broken off in (ON)-30 in 30 minutes.In addition,, existing vegetable compartment is imagined, replaced electrostatic atomization apparatus 131 to spray mist with above-mentioned BOX condition with supersonic atomizer and carry out same test as contrast.
As shown in Figure 6ly know that in this embodiment, degerming rate less than 30% is relative therewith during with supersonic atomizer, under situation about atomizing with electrostatic atomization apparatus, having 3 days is more than 95%, and 7 days is the high antibacterial effect more than 99%.
The mould spore that sends usually stretches out mycelia and grows.Since the mycelia that sends by as the mist that produces of above-mentioned mode in the ozone or the free radical that are comprised remove, therefore mouldly no longer can extend mycelia and by deactivation (not activation), the result is mould to be suppressed growth.So use through destroy mould mycelia finally make the bacterium deactivation promptly promote to die (killing) degree ozone or hydroxyl free radical amount rather than powerfully make the amount of the ozone or the hydroxyl free radical of mould degree of dying itself to moment, can not have the mould growth of inhibition in the scope of influence thus in fresh-keeping of vegetables property to above-mentioned that kind.
Next, Fig. 7 is illustrated among the BOX that is envisioned for refrigerator vegetable chamber the result who confirms as the bacteria-eliminating efficacy of the black mould of mould representative bacterial classification.
Experimental condition is being set at: temperature is about 5 ℃ in the about 70L of BOX capacity, BOX, and relative humidity is more than the 90%R.H in the BOX, and electrostatic atomization apparatus 131 is located in the BOX.In addition,, imagine existing vegetable compartment, spend except the device behind the electrostatic atomization apparatus 131 and carry out same test as contrast.In addition, the spray mould mould number that initially swims that make to supply test is more than 1000/100LAir (air).The mensuration of bacterium number is measured with air sampling attraction method.
As shown in the figurely can confirm that the electrostatic atomization apparatus running of this embodiment was compared with collating condition after 60 minutes, can obtain 99% bacteria-eliminating efficacy, not only also have bacteria-eliminating efficacy to vegetables, cabinet inner surface but also to the bacterium that swims in the refrigerator cabinet.
Usually the protein of furcella that is present in virus surface (spike) of virus and so on the nutritional labeling that parasitizes saliva etc. is bred.As shown in the figure; The ultramicrofine mist that comprises free radical that is produced spreads in around the virus and decomposes furcella (protein); Therefore virus can not parasitize nutrient; Thereby by deactivation and suppress its breeding; So use protein through the break virus surface finally to make the amount rather than powerful of ozone or the hydroxyl free radical of the degree that viral deactivation promptly promotes to kill kill ozone or the amount of hydroxyl free radical of the degree of virus itself to moment, thus can the mould growth of inhibition in the scope that fresh-keeping of vegetables property not have as above-mentioned influences.
Next, Fig. 8 is illustrated in the result of the antiviral effect of the electrostatic atomization apparatus of confirming this embodiment 1 in the BOX test.
Experimental condition is set at: temperature is a room temperature in the about 30L of BOX capacity, BOX, and relative humidity is more than the 90%R.H in the BOX, the electrostatic atomization apparatus 131 of this embodiment 1 is located in the BOX and is made it connect the running rate that broke off in-30 minutes with 30 minutes turn round.In addition,, imagine existing vegetable compartment, spend except the device behind the electrostatic atomization apparatus 131 and carry out same test as contrast.The deactivation of virus compares with the logarithm value of 50% TCID (TCID50).The logarithm value of TCID50 small virus deactivation more is high more, if there be poor more than 2 in the LogTCID50 value, then can be described as and has significant difference.
Can confirm from this result of the test, under 2 hours situation of the electrostatic atomization apparatus that makes this embodiment 1 131 running, with respect to initial stage and contrast (empty (blank)), owing to have poor more than 2 at LogTCID50/ml, so have viral deactivation effect.
In addition, although scheme not shownly, also can obtain the bacteria-eliminating efficacy same through the staphylococcus aureus that staff inhabits in the refrigerator cabinet with coliform for stronger anti-drying.In addition, can obtain high bacteria-eliminating efficacy too to pathogens such as O-157 or MRSA, influenza viruses, therefore clearly to bacterium, mould, virus etc. on a large scale bacterial classification have high bacteria-eliminating efficacy.
Next, the appropriate value to the amount of ozone concentration in the vegetable compartment 108 and free radical uses Fig. 9 and Figure 10 to describe.Fig. 9 is the figure of the relation of expression fresh-keeping of vegetables property and ozone concentration.Represent antibacterial activity value and the sense evaluation of estimate of outward appearance under each ozone concentration.Satisfying ozone concentration is more than the 10ppb, target antibacterial activity value reach more than 2.0 (with the relative bacterium number of contrast be below 1/100).In addition, the apparent condition of vegetables is that 2.5 ozone concentrations when above of edible tolerance limit are 10~80ppb.Ozone concentration is that 10ppb receives the influence the bacterium of vegetable surface breeding when following, the corrupt state deteriorating that advances of vegetables.In addition, when preserving under the ozone concentration more than 80ppb since to the high spinach of ozone sensitivity, tomato, green onion, lettuce etc. by the ozone layer destroying cell, and produce because of leaf bleaches to wait and hinder the quality badness that causes, so be inappropriate for the preservation of vegetables.
On the other hand with regard to foul smell, in the domestic refrigerator ozone concentration be 30ppb when above because the people smells the ozone flavor and can produce unplessantness displeasure, therefore must it be controlled at below the 30ppb.
According to the above, the ozone concentration that is suitable for the vegetables preservation is 10~80ppb, under this concentration, the microbial reproduction in the vegetable compartment is had the inhibition effect, is can not bring the concentration of infringement to the tissue of vegetables on the other hand.And vegetables detect drop ozone and are harmful substance, are the organism defense reaction that activates vegetables, promote the generations such as phylloerythrin, vitamin as polyphenoils, the concentration that nutrient is expected to increase.But in the family expenses refrigerator, in order not bring the unplessantness displeasure of ozone flavor to the user, it is preferred that ozone concentration is made as below the 30ppb, so suitable ozone concentration is the scope of 10~30ppb in the domestic refrigerator.
On the other hand, the amount with the produced simultaneously free radical of ozone is controlled to be 10~50 μ mol/L.Also the same with ozone for biology, the measuring of free radical is harmful substance for a long time, but the words of trace are to activate the organism defense reaction, generate polyphenoils such as a large amount of phylloerythrin, vitamin, help strengthening the material of patience.Be the concentration that concerning microorganism, produces cytoclasis during 10~50 μ mol/L, but be the concentration that can not bring bad influence, but can expect that nutrient increases in the organism defense reaction vegetables.
Confirm that in experiment the amount of free radical is the cellular damage that will produce lettuce more than the 100 μ mol/L, makes quality badness.In addition, suppress, can confirm that the above antibacterial activity of 10 μ mol/L is more than 2.0 for microorganism.Therefore, judge that amount that we can say free radical is to be preferred about 10~50 μ mol/L from antibacterial effect, fresh-keeping of vegetables property two aspects.
In addition, result shown in Figure 10 free radical appropriate amount for calculating according to the result who confirms with the higher lettuce of sensitivity is because it is different because of the kind of vegetables to envision suitable scope; Therefore may not be restricted portion; But when domestic refrigerator is preserved, come setting range through using the result who obtains by the highest lettuce of pair cell damage sensitivity, thereby can guarantee sufficient security; Promptly antibacterial effect can either be improved, fresh-keeping of vegetables property can be guaranteed again.
So; The mist electricity in vegetable compartment 108 that is injected in the vegetable compartment 108 is attached to the vegetables of positively charged or the surface and the cabinet internal face of fruit; And invade in the fine recess of vegetables or fruit surface; Mould, bacterium, yeast and virus that interior pressure energy through fine mist will be attached to recess are peeled off, and through the oxygenolysis of ozone and free radical its oxidation Decomposition are removed.On the other hand, invade in the pore of wall, make the inner dirt in hole equally or harmful substance is floated and decompose through ozone oxidation its decomposition is removed.
In addition,, make the hydrone free radicalization in the mist, generate hydroxyl free radical, except the oxidizing force of ozone,, can improve the decomposability of microorganisms such as bacterium or mould, yeast and virus also through the oxidizing force of hydroxyl free radical through mist is applied static.Thus, though when running economize on electricity in-cabinet temperature rise, also can keep the fresh-keeping property of vegetable and fruit etc., and can realize energy-conservation.
In addition; In above-mentioned experiment; With as be that representative is illustrated in the vegetable compartment of maximum temperature band 108, but owing to tell on, even so in the storerooms such as refrigerating chamber of the temperature band lower, also can play same effect than vegetable compartment 108 at the maximum temperature band.
Next, use the control block diagram of Figure 12 to describe.

Press certain hour and take out these data, set operation mode by control module 54, compressor 109, cooling fan 113, the temperature-compensating that can automatically change as the electric load parts are set with the temperature of heater 56, each storeroom.At this; If detect to below the 5Lx through illuminance transducer 36; This state is through certain hour, and below the temperature that is cooled to stipulate, then entering suppresses the compressor revolution or prevented blowdown firing constant pitch electric operation automatically; Make as the LED39 that reports the unit and light or extinguish certain hour; Make electrostatic atomization apparatus 131 action, generate the mist that contains ozone or hydroxyl free radical, realize spatter property, degerming, deodorization through it being ejected in the storeroom (or flow out from mist jet private space 150) and it being circulated.
As above; In this embodiment, following refrigerator can be provided, promptly; Control module is controlled and is made the temperature of storeroom rise when economizing on electricity running; And electrostatic atomization apparatus is worked, supply with mist, even make under the situation of in-cabinet temperature rising because of the running of economizing on electricity from the storeroom of mist jet private space after temperature rises that stores the high concentration mist of supplying with from electrostatic atomization apparatus; Also can supply with to contain and can be suppressed at the microorganisms such as mould or bacterium yeast and virus that adhere to vegetable surface in the cabinet and increase and keep the ozone of fresh-keeping property and the mist of hydroxyl free radical, and the running of can economizing on electricity automatically.
In addition; Under the situation of the electrostatic atomization apparatus that possesses function attachment device that produces hydroxyl free radical and the mist that injection contains hydroxyl free radical; Because the durable time of hydroxyl free radical is short; Therefore it is preferred in compartment interior the function attachment device being set as far as possible, can realize antibacterial effect reliably thus.
So; More energy-conservation in order to realize; Under the time set of carrying out the running of the to economize on electricity situation that the automatic economize on electricity of length is turned round, especially because be the higher storeroom of temperature in the storeroom, so the possibility that the microorganisms such as mould or bacterium yeast and virus that in cabinet, adhere to vegetable surface increase height; But through possessing function attachment device illustrated in the embodiment 1; Can and keep the running of economizing on electricity automatically on the basis of fresh-keeping property in the increase that suppresses microorganisms such as these bacterium yeast and virus, in real-world operation, can on the basis of keeping fresh-keeping property, realize more energy-conservation.
In addition; In this embodiment; Make the electrostatic atomization apparatus running during economize on electricity running; But also can when turning round usually, also carry out the running of electrostatic atomization apparatus, when the economize on electricity running, make the time lengthening of electrostatic atomization apparatus work, perhaps the amount of ozone concentration or hydroxyl free radical is increased to greater than common concentration through the discharge ability (for example voltage or electric current) that increases electrostatic atomization apparatus.Thus, can improve degerming ability, strengthen freshness and keep, and can obtain the energy-saving effect that rises and produce because of in-cabinet temperature.
