Description

Refrigerator

Technical field

The present invention relates to refrigerator.

Background technology

To keep the function of food freshness, produce anion, have anion is watered the refrigerator that drenches the function on food, be disclosed in the Japanese patent laid-open 8-145545 communique.Based on anion (is mainly O ₂ ^-) water pouring on food, can not cause bad influence, and concentration that can be extremely low suppresses under the prerequisite of the knowledge that microorganism or germ grow existing institute motion in the invention of above-mentioned communique to human body.

Figure 13 is that expression is recorded in the figure of 1 example that above-mentioned spy drives the refrigerator with anion generating device of flat 8-145545 communique.Among Figure 13,101 is that refrigerating chamber, 102 is that refrigerating chamber, 103 is that cooling chamber, 104 is that vegetable compartment, 105 is that compressor, 106 is that vaporising device, 107 is that fan (cold air pressure fan), 108 is an anion generator, the anion that is produced by anion generator 108 is by fan 107, sends into simultaneously with cold air that each is indoor.

But, because the generation of anion, electrode is the occasion of ac high voltage effect especially, can produce foul smell and cation simultaneously, and can change the color of food because of ozone, or decolouring very strong of oxidizing force of reducing freshness, especially ozone, can obviously make the quality of food reduce, therefore in order to make ozone not in the storage indoor circulation, cation acquisition electrode and ozone decomposition catalyst must be set near anion generator, constitute very complicated structure, and cost an arm and a leg.Therefore, the technology that above-mentioned spy opens flat 8-145545 communique record is to be conceived to DC voltage is added on anion generator outward, makes its unlikely generation ozone and cation.

In addition, above-mentioned spy opens in the flat 8-145545 communique, at the inside of arbitrary storeroom side configuration anion generator, is under the situation of drawer type at this storeroom, and the electric wire of retractable is connected on the power supply of anion generator.

Summary of the invention

As above-mentioned shown in Figure 13, ion generating unit 108 is arranged in the conduit of being located at courtyard portion, formation is sent into anion under each indoor situation by fan 107, make anion attached in the plastic conduit, the amount that can cause directly blowing to the anion of food (the especially greengrocery in the vegetable compartment) reduces, and causes the problems such as minimizing of degerming, antibacterial effect.Promptly, the occasion of Gou Chenging as shown in Figure 13, anion generator is arranged among vegetable compartment cooling air air-supply path far away, therefore the anion of not at all easy generation is but absorbed by plastics system passage on every side in by narrow ventilating duct, it is few to the quantity of the anion of vegetable compartment to cause spuing, and reduces degerming, antibiotic problems such as effect.Therefore, propose to be necessary to make anion generator, effectively use anion as much as possible near storeroom (especially vegetable compartment).

In addition, occasion at the inside of storeroom side configuration anion generator, though the effect of anion spray is improved, but occasion at the such drawer type storeroom of vegetable compartment, the electric wire of retractable must be connected on the anion generator, have the possibility that causes loose contact or broken string by damaged wire because make for a long time thus, in addition, also there is the problem accommodating container of vegetable compartment can not be pulled out fully washing etc.

In addition, top in airtight vegetable compartment is provided with independently anion generator and pressure fan, when flowing through the cooling air in the vegetable compartment vegetables accommodating container of main body (the constitute vegetable compartment) outside and cooling off indirectly, having the vegetable compartment that covers vegetables accommodating container top covers, because of from reserves such as vegetables institute moisture evaporated dewfall, drip to the problem on the foodstuff storing in the vegetables accommodating container.Therefore, in order to prevent dripping of above-mentioned moisture, the formation that requires realization to reach really.

In addition, as have anion and produce the anion generator of accepting electrode with electrode and cation and construct incorrectly, can produce harmful ozone, cause the variable color or the armpit look of foodstuff storings such as greengrocery, acceleration is to the problems such as injury of vegetables.Therefore require to realize producing the few anion generator of ozone.

In addition, top in airtight vegetable compartment is provided with anion generator, and the occasion of little article storing container is set on the top of the vegetables accommodating container that constitutes the vegetable compartment main body, the foodstuff storing of greengrocery in the little article storing container on upper strata contacts with anion easily, but the greengrocery foodstuff storing in the greengrocery accommodating container of little article storing container downside is then covered by the little article storing container on upper strata and can not contact anion, has and can not keep the problems such as freshness of greengrocery for a long time.Therefore, even seek a kind ofly when on the vegetables accommodating container of the main body that constitutes vegetable compartment, the formation of little article storing container being set, can realize the structure that contacts with anion equally for the greengrocery in the vegetables accommodating container of little article storing container downside.And the foodstuff storing state that pile up like a mountain can cause the convection current of air bad down in the little article storing container on upper strata, can not scatter anion equably for foodstuff storing, therefore seeks to realize having good convection current and increase the air mass flow that contains anion.

In addition; when the vegetable compartment that is positioned at vegetable compartment (constituting the vegetables accommodating container of the main body of vegetable compartment) top covers the installation anion generator; in order to protect the breakage that when foodstuff storing or people's finger contacts, causes the electrode of its anion generator; grid-like protection member is set, but can absorbs the quantity that the anion that is produced reduces anion according to the material of protection member.Therefore, as the material of above-mentioned protection member, the essential material of selecting a kind of difficult minimizing anion.

Also have, when the cold air of the storeroom cooling beyond the vegetable compartment being blown be also used as sending into of anion and use fan with fan, when the temperature degree is low outside winter, the cold air air-supply that links the running of refrigerator uses the running rate of fan low, can reduce the air output of anion, the effect that makes anion produce reduces.Therefore, propose to need that a kind of running rate that is not subjected to refrigerator influences, have anion independently and send into necessity with fan.But be provided with independently anion and send into when use fan this moment, must will occupy its required space, and the internal volume of the food storage of minimizing refrigerator, so seek a kind of structure that does not reduce its internal volume as far as possible.

In addition, carry the separate fan of the special use that anion that ion generator produced uses if when covering with the blower cover that is installed on the vegetables chamber cap, just in case the pressure fan of anion air-supply usefulness takes place unusual, even and cause being in the possibility that halted state is not also noticed, under its occasion, have the freshness that to keep foodstuff storing and the problem of damaging vegetables ahead of time.Therefore, expect that separate fan that a kind of user can easy identification sends into the special use that anion uses rotates the structure of situation.

In a word, forced ventilation is set imports the direct cold storage chamber of cooling off air and cooling off, and directly will not cool off in the air importing storeroom, from on every side indirectly the refrigerator of the indirect cold storage chamber of cooling, keep for the freshness of suitably carrying out the indoor food of indirect cold storage, have all investigation problems.

The present invention grinds wound in view of above-mentioned technical task to form, the formation of the invention of one of the application's representativeness is, the direct cold storage chamber of cooling off being provided with forced ventilation importing cooling air, and the accommodating container that disposes accommodating container and this accommodating container in storeroom covers, can cool off indirectly in the refrigerator of the indirect cold storage chamber in the above-mentioned accommodating container, setting makes the circulation pressure fan of the circulating cold air in the above-mentioned accommodating container on above-mentioned accommodating container lid, and ion generator.

Among Fig. 1,1 is refrigerator, 2 is the refrigerating chamber (cold storage room) of door open and close type, 3 are pull-out type vegetable compartment (cold storage room that greengrocery is used), and 4,5 is the pull-out type refrigerating chamber, and 6 is compressor, 7 is the fan (cold air pressure fan) of refrigerating chamber 2 and vegetable compartment 3 usefulness, 8 is the cooler of refrigerating chamber 2 and vegetable compartment 3 usefulness, and 9 is the fan (cold air pressure fan) of refrigerating chamber 4 and refrigerating chamber 5 usefulness, and 10 is the cooler of refrigerating chamber 4 and refrigerating chamber 5 usefulness.In this example, but refrigerating chamber 2 and refrigerating chamber 4 are to constitute the storeroom that forced ventilation imports the direct cooled that cools off air and cool off with refrigerating chamber 5, vegetable compartment 3 directly will not cooled off the air importing and be located at indoor vegetables accommodating container 14 (consulting Fig. 2), but form from the storeroom of the indirect cooled that cools off indirectly on every side of vegetables accommodating container 14.And, in this example, though vegetable compartment 3 is the middle levels that are configured in refrigerator, but as when taking structure described later, can dispose the position of vegetable compartment arbitrarily.

As shown in Figure 2, the vegetable compartment 3 of this example is between the diaphragm plate 11 and diaphragm plate 12 of refrigerator 1.Vegetable compartment 3 is to comprise: the telescopic vegetables accommodating container integrally formed with vegetable compartment door 13 (constituting the vegetables accommodating container of the main body of vegetable compartment) 14; Cover the vegetables chamber cap 15 above the vegetables accommodating container 14; The maintained little article storing container in ground (little article unscrambled containers) 16 can be pulled out at vegetables accommodating container 14 in the upside the inside of mounting in vegetables accommodating container 14; Be configured in the anion generator 17 above the vegetables chamber cap 15; Be configured in the independent vegetable compartment fan 18 of the vegetable compartment special use above the vegetables chamber cap 15; Be installed in above the vegetables chamber cap 15, the institutes such as blower cover 19 that cover anion generating device 17 and vegetable compartment fan 18 constitute.

Diaphragm plate 11 has the function of door with the liner of vegetable compartment door 13 of absorption refrigerating chamber 2 in a skeleton part that forms refrigerator 1, the inboard of this diaphragm plate 11 is provided with the space.Vegetables chamber cap 15 is installed in the below of diaphragm plate 11, at the inner crest face of this vegetables chamber cap 15, is equipped with anion generator 17 and vegetable compartment fan 18, and the blower cover 19 that covers anion generator 17 and vegetable compartment fan 18 is installed in the top of vegetables chamber cap 15.Promptly, in diaphragm plate 11, take in anion generator 17 and vegetable compartment fan 18 and blower cover 19 in the flat space of side compactly, and, be not to be integrally formed into telescopic vegetables accommodating container 14 with vegetable compartment door 13, but on vegetables chamber cap 15 as the fixed component of freezer 1, anion generator 17 and vegetable compartment fan 18 are installed, therefore with existing telescopic member on anion generator is installed structure compare, can live wire possibility of broken string, its line is constructed also comparatively simple.

In addition, blower cover 19 is for can be from top identification vegetable compartment fan 18, and its part is formed by transparent or semitransparent material at least, and the base plate 20 of refrigerating chamber 2 that is positioned at blower cover 19 upsides simultaneously is same with transparent or semitransparent material formation.

And above the blower cover 14, airtight by vegetables chamber cap 15 and blower cover 19, the vegetable compartment 3 that this is airtight is utilized said fans (cold air pressure fan) 7 cold air of being sent, and forms the periphery cooling from vegetables accommodating container 14.

Cover on the vegetables chamber cap 15 above the vegetables accommodating container 14, be equipped with air suction inlet 15a and outlet 15b, utilize vegetable compartment fan 18 to blow out from outlet 15b by vegetable compartment fan 18 from suction inlet 15a inhaled air (cold air), formation can be in vegetables accommodating container 14 forced circulation.And, the anion that anion generator 17 is produced is the downwind side that anion generator 17 is configured in vegetable compartment fan 18, therefore with the cold air of being sent from outlet 15b, be spray form and blown on the greengrocery that is attached to vegetables accommodating container 14 and little article storing container 16.

Promptly, in this example, anion is owing to absorbed by plastic material easily, therefore as above-mentioned prior art, be not to make anion pass through mode in the cooling air circulation pipeline of refrigerator, but the cold air that will contain anion generator 17 anion that produces blow with direct spray form and is attached on the vegetables.And forced circulation is enclosed in the cold air in the vegetable compartment, so anion can arrive each corner portion of vegetables accommodating container 14, can greatly improve the effect that anion is kept for food freshness.

As shown in Figure 3, anion generator 17 is provided in and is positioned at directly over the discharge opening 15b, and vegetable compartment fan 18 is the weather sides that are provided in anion generator 17, and in the centre position of suction inlet 15a and outlet 15b.Vegetable compartment fan 18 is in order to ensure the air quantity that contains anion, be to adopt the big propeller type fan of diameter, in the height dimension that can be accommodated in above-mentioned diaphragm plate 11 (consulting Fig. 2), the discharge side formula of vegetable compartment fan 18 is towards the below, and tilt to set to make it to have from the gradient below horizontal direction 30 degree, during according to the vegetable compartment fan 18 of this example of taking above structure and mounting position, can reach guaranteeing of abundant air quantity simultaneously, and setting in the flat narrow space.In addition, owing to be propeller type fan, therefore as described later, vegetable compartment fan 18 can be confirmed its rotation/halted state simultaneously easily.

In addition, as shown in Figure 3, the below of the vegetable compartment fan 18 of vegetables chamber cap 15 upper face sides, the dehumidifying deodorizing sheet 21 of stickup constitutes can make from the wind of vegetable compartment fan 21 is direct on this dehumidifying deodorizing sheet 21 and clashes into surgingly.Greengrocery is more for a long time in vegetables accommodating container 14 for this dehumidifying deodorizing sheet 21, can absorb moisture and maintenance that greengrocery bears, be about to moisture when Once you begin dry in the vegetables accommodating container 14 when vegetables reduce and emit the humidity that improves in the vegetables accommodating container 14, have the function that to regulate humidity in the vegetables accommodating container 14 automatically; Absorb the function of stink; And, have the water droplet that will be positioned at after the blower cover 19 inner face dewfall on anion generator 17 tops, reach the water that flows down behind the lid and suck, prevent that water droplet from dripping to the function of vegetables accommodating container 14.In addition, therefore dehumidifying deodorizing sheet 21 can adsorb the stink composition effectively owing to be moisture state.

Dehumidifying deodorizing sheet 21 is in order to absorb the water droplet that drips from blower cover 19, and the water droplet that is provided in dewfall on the inner face of anion generator 17 upper positions that can stop blower cover 19 is concentrated its position of dripping.Wherein, dewfall is at the moisture above the side taken in of the anion generator 17 of blower cover 19, be owing to make vegetables accommodating container 14 airtight when closing vegetable compartment door 13, by by said fans (cold wind pressure fan) 7 cold air of being sent, vegetables accommodating container 14 is cooled off indirectly, make temperature in the vegetables accommodating container 14 than its temperature outside height, make the water evaporates that is contained in greengrocery utilize vegetable compartment fan 18 circulation time in vegetables accommodating container 14, touch the top part of anion generator 17 of the blower cover 19 of cooling, with the moisture cooling and dewfall.

Wherein, this example as shown in Figure 3, and the 19a of courtyard portion of anion generator 17 tops of blower cover 19 is oblique towards 21 inclinations of dehumidifying deodorizing sheet, constitutes the water droplet that makes the 19a of courtyard portion dewfall, falls to the top of dehumidifying deodorizing sheet 21.In addition, in this example, though only the 19a of courtyard portion with anion generator 17 tops of blower cover 19 is oblique towards 21 inclinations of dehumidifying deodorizing sheet, but the courtyard portion of vegetable compartment fan 18 upsides of blower cover 19 tiltedly (also can be tilted) equally towards rightabout with the 19a of courtyard portion towards 21 inclinations of dehumidifying deodorizing sheet.

And among Fig. 3,19b is the transparency window member that is positioned at vegetable compartment fan 18 tops, is arranged on blower cover 19.

As previously mentioned, in this example, on the vegetable compartment 3 except vegetables accommodating container 14, the overlapping shallow little article storing container 16 of height dimension that storage usefulness such as the little vegetables of arrangement are arranged of portion on the big vegetables accommodating container 14, this little article storing container 16 is positioned at the downside of outlet 15b.Therefore, under this state, though the anion that the greengrocery in this little article storing container 16 is sent here with sneaking into circulation cold air contacts, if but do not work hard in shape at little article storing container 16, little article storing container can cover flowing of circulation cold air, therefore can make the greengroceries in the vegetables accommodating container 14 be difficult for the contact anion, and during the freshness that shortens the greengrocery in the vegetables accommodating container 14 keeps.

At this, the present embodiment form is in order to make the circulating cold air in the vegetables accommodating container 14 good, as shown in Figure 4, in the bottom surface that forms little article storing container 16 and the crest line portion inboard of side, wear a plurality of slit 16a, but the cold air of mixing circulation makes anion fall by slit 16a in view of the above, constitutes the greengrocery that can contact vegetables accommodating container 14 really.In addition, the position, shape, the quantity that are located in the slit (open-work) of little article storing container 16 can be any, if but be arranged on the downside of little article storing container 16, the most suitable for the formation in the circulating cold air path in the vegetables accommodating container 14 described later.

In addition, for obtaining the circulation of cold air in the good vegetables accommodating container 14, increase the amount of the circulating air in the vegetables accommodating container 14, promptly in order to make anion contact greengrocery in the vegetables accommodating container 14 in a large number, in this example as shown in Figure 5, the front panel of little article storing container 16 is to set it highly to be lower than the side panel or the backplate of little article storing container 16, between the front panel upper end and vegetables chamber cap 15 of little article storing container 16, the gap that air can fully circulate is set in view of the above.

As mentioned above, the slit 16a of the above-mentioned position by being located at little article storing container 16, and be located at the front panel upper end of little article storing container 16 and the gap between the vegetables chamber cap 15, make the cold air that mixes anion utilize the action of vegetables fan 18, the direction of arrow circulation of representing in as Fig. 5 in airtight vegetables accommodating container 14, constituting can the little article storing container 16 of comprehensive contact and the greengrocery of vegetables accommodating container 14.In addition, by making about 1/2 of the degree of depth (highly) 80～100mm that the front panel upper end of being located at little article storing container 16 and the clearance height size L1 between the vegetables chamber cap 15 form little article storing container 16, even when in vegetables accommodating container 14, putting into a lot of food such as greengrocery in view of the above, also can confirm the convection current of air in its unlikely obstruction vegetables accommodating container 14.And, set the front panel of little article storing container 16 and the distance between vegetables accommodating container 14 front panels is about 100～120mm at this.

But the front illustrates, because the generation of anion, the time spent of doing of giving AC high voltage for the electrode of ion generator is owing to can produce ozone (O simultaneously ³) and cation, therefore need anion passive electrode and ozone decomposition catalyst.At this, this example shows with interchange and converts direct current to, and adds negative DC voltage on the negative electrode of ion generator 17, makes it only produce anion.In addition, in case when producing corona discharge or glow discharge, oxygen molecule is given high-energy source and promoted the ozoniferous reaction of oxygen molecule,, the protective plate that is made of insulating materials is set between two electrodes of anion generator 17 therefore in order to make it not produce corona discharge or glow discharge.

That is, in this example,, between needle electrode (negative electrode) 31 and annular electrode (positive pole) 32 of anion generator 17, the projecting height be higher than two

electrodes

31,32 is set, the ring protection plate 33 that constitutes by insulating materials as Fig. 6, shown in Figure 7.In this example, the projecting height H2 of needle electrode 31 is 4.5mm, and the projecting height of annular electrode 32 is 3.0mm, and changing the height measurement ozone generating amount of protective plate 33 and the experimental result of anion generation this moment is as the table among Fig. 3.From this experimental result as can be known, when the height dimension H1 of protective plate 33 was 8～9mm, the generation of ozone can be suppressed at below 0.1～0.01 of low amount, but the slightly a spot of 6.45～20.93k of ozone generating amount/cc is not an appropriate value.On the other hand, when the height dimension H1 of protective plate 33 is 6～7mm, have sufficient anion generation, the value that the generation of ozone is scaled concentration in the vegetables accommodating container is 0.009～0.018ppm of abundant low value, can confirm as appropriate value.

In addition, in this example, when putting into vegetable compartment 3 with hand, the user of refrigerator in order to prevent to get an electric shock etc., and for the breakage that prevents anion generator 17 etc.,, as shown in Figure 8, plastic grid-like protection member 34 is set at the downside of anion generator 17.This grid-like protection member 34 forms shallow wrist shape, and its bottom surface is to form grid-like (protecting netted) at least, is made into the shape that anion can pass through.

But anion be in case when positively charged plastics etc. contacts, can reduce its amount, and therefore to be difficult for charged plastic material with selection be good to grid-like protection member 34.Fig. 9 is the experimental result that the anion of expression when changing the plastic material of grid-like protection member 34 measured number, and Figure 10 is the rerum natura table of the employed plastic material of experiment of presentation graphs 9.As Fig. 9, shown in Figure 10, the occasion of PBT (polybutyleneterephthalate), the measurement quantity of anion is many, and volume resistance power is also bigger, so this example does one's utmost to form grid-like protection member 34 in order not reduce the amount of anion with PBT.In addition, though be not used in experiment, PPS (polyphenylene sulfides) has the characteristic identical with PBT, can use as PBT equally.

In addition, as discussed previously, if will cool off storeroom is used beyond vegetable compartment or the vegetable compartment cold air blows and uses fan, when dual-purpose is sent into the fan of usefulness as anion, when the outer temperature degree (indoor temperature) in winter is low, link the running of refrigerator and the cold air air-supply of the control of turning round forms low running rate (shortening of air-supply time) with fan, therefore, the air output of anion also reduces, and can not scatter anion fully to vegetables etc., and reduce the effect that anion produces.Therefore, in this example, the fan 7 of above-mentioned refrigerating chamber 2 and vegetable compartment 3 usefulness, or the fan 9 of refrigerating chamber 4 and refrigerating chamber 5 usefulness is to form respectively, and force air is circulated, formation is provided with the formation of the vegetable compartment fan 18 that is used to send into anion, constitutes this vegetable compartment fan 18 is not linked with the running rate of refrigerator, as the fan that can independently control.

Promptly, in this example, the vegetable compartment fan 18 of anion air-supply (distribution) usefulness is not synchronous with the running of said fans 7, but drive at the appointed time with independent operation, winter and summer are that anion is spread all in the vegetables accommodating container 14 fully equally, the running of control vegetable compartment fan 18.In addition, the running of the running of anion generator 17 and vegetable compartment fan 18 is synchronous.

Perhaps, make the running of vegetable compartment fan 18 and anion generator 17, high (when outer temperature degree are high) such as summers of refrigerator running rate as shown in figure 11, running is controlled to be with said fans 7 synchronous fully, when refrigerator running rate low (when outer temperature degree hang down) such as winters, make itself and said fans 7 runnings begin synchronous entry into service, can stop the prolongation running of laggard line number minute equally in the running of fan 7, even, anion can be spread in the vegetables accommodating container 14 fully equally in refrigerator running rate low winter.

Also have, in the refrigerator of this example, make the structure of the rotation status of the easy Visual Confirmation vegetable compartment of the user that can make refrigerator fan 18.Promptly, in a single day vegetable compartment fan 18 enters in user's the eye, during structure that formation can monitor easily from the outside, when unusual, arouse attention easily, the user is relieved, therefore this example is as above-mentioned, when the blower cover 19 that is positioned at vegetable compartment fan 18 tops is provided with transparency window member 19b, form the base plate 20 of the above-mentioned refrigerating chamber 2 that is positioned at blower cover 19 upsides with transparent material, in view of the above when opening the door of refrigerating chamber 2, as shown in figure 12, the user can directly confirm the operational situation of vegetable compartment fan 18 with naked eyes.And, because vegetable compartment fan 18 is the fan of propeller type, and make vegetable compartment fan 18 lodging ground tilted configuration, therefore form the rotary state that can confirm vegetable compartment fan 18 more easily.

As described above, can be if make in advance from the structure of visual observation vegetable compartment fan 18 rotation appearance, when showing that refrigerator is sold etc., salesmans etc. illustrate that to client anion sends into the appearance of Air Blast fan (vegetable compartment fan) rotation of using easily, and just in case can find the fault place easily when breaking down.

As mentioned above, refrigerator according to this example, will be as the independently circulation pressure fan (vegetable compartment fan) that is used to make the circulating cold air that is enclosed in the vegetable compartment accommodating container of indirect cooled storeroom, be arranged on the storage chamber cap (vegetables chamber cap) that covers vegetables accommodating container top, therefore can form the convection current of air in the good vegetables accommodating container, make the surface of the food such as greengrocery in the cooled air contact of the volume vegetables accommodating container, obtain the homogenising of food temperature early, but the long term maintenance freshness.

Again, owing to anion generator is arranged on the discharge side (leeward) of independently above-mentioned vegetable compartment fan, therefore anion does not resemble in the past by in the conduit and do not cause anion to be adsorbed on the conduit etc., but the anion volume is dispersed in the vegetables accommodating container, therefore the screening effect of anion can suppress moisture and evapotranspires, and is keeping the fresh degree of greengrocery etc.

And cover in the vegetable compartment that covers vegetables accommodating container top suction inlet and outlet are set, anion generator is set directly over outlet, therefore the anion that produces directly can be expelled in the vegetables accommodating container effectively.And, make the air of vegetables accommodating container inner circulating reflux, directly suck from suction inlet and be back to the vegetable compartment fan, therefore can reduce the internal circulating load of anion, therefore anion can be dispersed on the food of greengrocery in a large number, this point has big food freshness equally and keeps effect.

In addition, in the space of the diaphragm plate member inboard that is arranged at refrigerator, configuration anion generator and vegetable compartment fan, and be arranged to make vegetables chamber fan to tilt to suck to be directed upwardly, can reduce it equally height is set even therefore have large diameter fan, but therefore can not reduce the volume of the foodstuff storing in the refrigerator, in the flat space of being located at diaphragm plate member inboard, the space wants disposition good, can dispose compactly, carries out effective utilization of refrigerator internal volume.

Also have, anion generator and vegetable compartment fan are the tops that is configured in the vegetables chamber cap that is fixed in diaphragm plate member below, but therefore compare with the structure that anion generator is installed on the drawer type member in the past, can live wire possibility of broken string, can obtain easy tie line simultaneously and construct.

And, even in the vegetables accommodating container formation of the little article storing container of configuration, can on little article storing container, form slit equally, so anion can pass through slit, can be simultaneously to the distribution of the greengrocery in vegetables accommodating container anion.Have again, between the front panel of little article storing container upper end and vegetables chamber cap, the gap that air is fully circulated is set, even so put into the food etc. of volume vegetables class etc., the convection current of still unlikely obstruction air can make the air that contains anion positively be circulated in the vegetables accommodating container.

Also have, the wind that the vegetable compartment fan is blown out is towards oblique below, but downside configuration dehumidifying (damping) deodorizing sheet at the vegetable compartment fan, this dehumidifying deodorizing sheet directly contacts the wind from the vegetable compartment fan, moisture content can absorb moisture for a long time in the wind, then emits the moisture that thin slice absorbs when forming dry wind on the contrary, therefore can control the humidity in the vegetables accommodating container just suitablely, can make its circulation by the airborne anion of unlikely minimizing, can effectively utilize anion.And can carry out the interior deodorizing of vegetables accommodating container simultaneously.

In addition, the courtyard portion at regulation position that is installed in vegetable compartment upper part of the cover blower cover is oblique towards dehumidifying deodorizing sheet inclination, dewfall is fallen on the dehumidifying deodorizing sheet at the water droplet of this inclination courtyard portion, make that water droplet is unlikely to drip from the vegetables chamber cap, and the dehumidifying deodorizing sheet can often keep moisture state, therefore can prevent drying extremely in the vegetables accommodating container, and be its amount of unlikely minimizing, therefore be not easy to reduce the internal circulating load of anion in the humidity that has more in nature of anion.

In addition, the insulation ring protection sheet that material constituted is set between the needle electrode of anion generator and annular electrode, can suppresses the generation of harmful ozone as much as possible.In addition, as needle electrode, as cathode side, make water droplet unlikely in view of the above the annular electrode that surrounds needle electrode, do not have the anxiety that causes electric pole short circuit continuously attached between the two poles of the earth with the cathode side of anion generator.

Also have, big with specific insulation, when for example the PBT material is discharged the grid-like protection member of side as the ion that is arranged on anion generator, can reduce the amount that sucts anion in a large number, and can scatter anion effectively.

Moreover, the duration of runs of anion generator and vegetable compartment fan and the cold air of the refrigerator that influenced by outer actuator temperature are blown with the running of the fan control of can turning round independently, perhaps the running rate of refrigerator low (when outer temperature degree hang down) such as winters, can begin entry into service synchronously with the running of fan with the air-supply of the cold air of refrigerator, stopping the prolongation that laggard professional etiquette fixes time in cold air air-supply with the running of fan turns round, even temperature degree low winter outside, still the anion of fully measuring can be disseminated in the vegetables accommodating container, can increase during the keeping of food freshness such as greengrocery.

And, because the user who the makes refrigerator structure of the rotary state of Visual Confirmation vegetables fan easily, therefore can give the user sense of feeling at ease, even the contingency fault also can be pinpointed the problems easily.And, in StoreFront, when the salesman carries out the explanation of commodity etc. to client,, can have the sale of convincingness owing to can see the vegetable compartment fan.

[invention effect]

According to above the present invention and since will make that the indoor circulating cold air of indirect cold storage uses between Connect the independent loops pressure fan of cold air storeroom special use, be arranged on the storage that wears outlet and suction inlet Above the chamber cap of Tibetan, therefore can form the convection current of good indirect cold storage room air, for Food surface in the cold air storeroom can make the cooling air circulation of volume indirectly, therefore can be early Obtain the homogenising of food temperature, freshness that can long term maintenance food.

In addition because anion generator is arranged on the leeward of above-mentioned circulation pressure fan, therefore negative from Son does not resemble in the past by being adsorbed in conduit etc. in the conduit, can with the anion volume intersperse among Cold storage is indoor indirectly, and the screening effect of anion can suppress moisture and evapotranspire, and keeps greengrocery etc. Fresh degree.

Also have and since the storeroom that covers top, indirect cold storage chamber cover arrange suction inlet with Outlet, anion generator be arranged on outlet directly over, therefore can be effectively will produce Anion direct connects that to be expelled to indirect cold storage indoor. And, in indirect cold storage indoor circulation The air that refluxes is to suck from suction inlet to be back to immediately in the circulation pressure fan, therefore can not reduce negative The internal circulating load of ion, anion can be dispersed on the food of greengrocery in a large number, and this point can obtain equally Big food freshness is kept effect.

In addition, in the space of being located at refrigerator diaphragm plate member inboard, the configuration anion generator And the circulation pressure fan, and the circulation pressure fan is tilted towards top suction ground setting, even tool Large diameter circulation pressure fan is arranged, still can reduce it height is set, therefore can not reduce in the refrigerator The volume that can store of food, and in the space of being located at diaphragm plate member inboard, its Space Elements Property is good, can dispose compactly, carries out effective utilization of refrigerator internal volume.

Also have, anion generator and circulation pressure fan are that configuration is fixed on diaphragm plate member below The upside of storage chamber cap, therefore with in the past can pull out member and installing the structure of anion generator Make and compare, can live wire possibility of broken string, and can obtain easy tie line and construct.

And, even above the accommodating container of indirect cold storage chamber, little article storing is held Device is configured in the formation of the downside that blows out the position of anion, owing to shape on little article storing container Become slit, can make anion pass through slit, for the accommodating container beyond the little article storing container Interior vegetables, simultaneously spreadable anion. In addition, on the front panel of little article storing container And between the storage chamber cap, even the gap that setting can make air fully circulate is therefore storage volume During the food such as greengrocery, the also convection current of unlikely obstruction air, therefore cold storage is indoor indirectly can Positively make air circulation.
