The specific embodiment
Below Shuo Ming the embodiment of the invention comprises the content that is used to address the above problem.
One embodiment of the present of invention below are described with reference to the accompanying drawings.
Among Fig. 1, Fig. 2, the 1st, refrigerator body, the 2nd, refrigerating chamber, the 3rd, refrigerating-chamber door.The 4th, vegetable compartment, the 5th, the door of vegetable compartment 4,4a are for the sealing that improves vegetable compartment 4, cool off and the vegetable container that disposes indirectly, and 4b is a housing.The 6th, contain the refrigerating chamber blower fan of deodorant or antiseptic, the 7th, the refrigerating chamber cooler.The 8th, refrigerating chamber, the 9th, refrigerating chamber door, the 10th, contain the refrigerating chamber blower fan of deodorant or antiseptic, the 11st, the refrigerating chamber cooler, the 12nd, constitute the compressor of the freeze cycle of refrigerator.
In the present embodiment, deodorant that contains in blower fan or antiseptic can be to adopt same substance to have two kinds of functions simultaneously, also can adopt different material performance deodorizing or antibacterial functions separately respectively.Below these material compositions are called deodorizing antibiotic (antibacterial and deodouring) agent.
In order to improve the ease for operation of refrigerating chamber 8, be divided into refrigerating chamber 8a and refrigerating chamber 8b, configuration contains the refrigerating chamber blower fan 10 and the refrigerating chamber cooler 11 of deodorizing antibiotic material overleaf.Refrigerating chamber 8a and refrigerating chamber 8b communicate with the space that refrigerating chamber blower fan 10 and refrigerating chamber cooler 11 are housed by passage.Cooler 7 and 11 and compressor 12, the pipeline by ANALYSIS OF COOLANT FLOW connects and composes freeze cycle.The cooling machine of present embodiment is refrigerating chamber 2, vegetable compartment 4, the refrigerating chamber of supplying with in the refrigerator body 1 by blower fan 6,10 through the cooled air of freeze cycle of above-mentioned cooler 7,11 and compressor 12 compositions 8.
Contain the refrigerating chamber blower fan 6 of deodorizing antibiotic material by driving, the air of each storeroom 2,4 is sucked by refrigerating chamber cooler 7, after 7 coolings of refrigerating chamber cooler, turns back to each storeroom 2,4, and to cooling off in each storeroom 2,4.Therefore, the air in each storeroom 2,4 all is circulation in storeroom 2,4.Because therefore the refrigerating chamber blower fan 6 that contains the deodorizing antibiotic material, has the function that can carry out deodorizing antibiotic to the foul smell of each storeroom 2,4 effectively in the place that the cold air of each storeroom 2,4 is concentrated.
Equally, drive the refrigerating chamber blower fan 10 that contains the deodorizing antibiotic material, the air of each storeroom 8a, 8b is frozen chamber cooler 11 and sucks, and after 11 coolings of refrigerating chamber cooler, turns back to each storeroom 8a, 8b, and to cooling off in each storeroom 8a, 8b.Therefore, the air in each storeroom 8a, 8b all is to circulate in storeroom 8a, 8b.Owing to contain the place that the cold air of refrigerating chamber blower fan 10 in each storeroom 8a, 8b of deodorizing antibiotic material is concentrated, therefore, have the function that to carry out deodorizing antibiotic to the foul smell in each storeroom 8a, 8b effectively.
Here, the blower fan 6 and 10 of the cold air that contains the deodorizing antibiotic material of just can circulating further describes with Fig. 3.The alar part material of blower fan is by plastics, and for example PP (polypropylene) 13 constitutes, and in order to keep rigidity, adds for example material of glass fibre 14 and so on.Contain after the deodorizing antibiotic material 15, adopt injection molding method to be processed into the wing of blower fan.
As the method that in PP, adds glass fibre and add the deodorizing antibiotic material, for example, can earlier the PP that does not contain glass fibre be dissolved, add and mix the deodorizing antibiotic material, then, in the PP that contains the deodorizing antibiotic material that forms, mix and add glass fibre.
Deodorizing antibiotic material 15 contains a large amount of plant polyphenols, for example, the composition that extracts from green tea is fixed in the pottery, and adjusts to the particle below 3 microns.
Plants such as green tea contain can be antibiotic or the material of deodorizing, and great majority have water-soluble or easily and water-soluble characteristic.Therefore, in the high environment of washiness, humidity, exist the composition of antibiotic or deodorizing easily to be dissolved in the water and make the impaired problem of efficient.So,, can adopt the pottery that contains mentioned component in order to address this problem.Even wash this structure, possibility antibiotic or that deodorizing becomes to distribute is also low, can its performance of long term maintenance.
This deodorizing antibiotic material 15 contains a large amount of polyphenol, and there are many OH bases in the surface, therefore, be adsorbed on especially easily on the glass fibre 14 on possess hydrophilic property surface, thus more even mixing in plastics.In addition, as shown in Figure 3, glass fibre 14 is communicated to inside from the surface of finished product easily, therefore, even the deodorizing antibiotic material 15 that accumulates in glass fibre 14 surfaces in finished product inside, also can effectively be brought into play deodorizing, antibacterial ability.For this reason, deodorizing, antibiotic ability increase, and can its performance of long term maintenance.Its result reduces operation and manufacturing cost.
The hydrophilic surface of glass and the OH of polyphenol base are easily by the intermolecular attraction combination.In addition, because glass fibre is long, whole fiber can not all be included in the resin, and a part is exposing surface easily.Therefore, combined fiberglass and polyphenol are the deodorizing antibiotic material of main body easily, and be added in the resin, a part that is adsorbed with the glass fibre of deodorizing antibiotic material is exposed finished surface, the foul smell composition enters from the gap that forms between glass fibre and the resin, like this, can effectively utilize the deodorizing antibiotic material of resin inside on apparent.
Deodorizing mechanism is described here.The deodoring materials of being made up of polyphenol has a large amount of OH bases shown in above-mentioned, for example, can following chemical reaction take place with the principal component methyl mercaptan that vegetables rot to produce stink, carries out deodorizing.
Equally, following chemical reaction can take place in the rotten smelly principal component ammonia of fish or meat, carries out deodorizing.
In addition, be in low temperature in the refrigerator, open and close refrigerator doors often, the place of placement nearly all is in the kitchen, and therefore, circulating cold air blower fan surface is stained with oil film easily, and Soft flocks etc. are adsorbed on this oil film, pile up the phenomenon of foul gradually from the top of the wing.The present invention can make the oil film of adhesion decompose because above-mentioned polyphenol can and decompose with the organic matter chemically reactive again, prevents the foul accumulation.
But, only from above-mentioned formation, contain in the blower fan can deodorizing or the material composition of decomposing organic matter be limited, the amount that can decompose is also limited.
In addition, as previously mentioned, polyphenol contains a large amount of OH bases, can with foul smell or organic matter chemically reactive, carry out deodorizing, decomposition, when contacting with moisture again, make regeneration OH base become possibility.The regenerative response of the product that forms with methyl mercaptan generation chemical reaction can be represented by the formula.
In addition, the regenerative response of the product that forms with ammonia generation chemical reaction can be represented by the formula.
Therefore, in refrigerator, there is the moisture that produces from food in a large number, thereby, make regeneration become possibility.
But in the foregoing description, blower fan is the downstream that is placed in cooler.After if blower fan is iced covering, can not contact with the foul smell composition, the phenomenon that deodoriging properties descends can be envisioned.Therefore, have not owing to freeze to cause deodoriging properties decline to carry out research, its result is described with Fig. 4 about the blower fan surface.
Fig. 4 does not have to become the repertory at water source and be provided with the humidification means in refrigerator when carrying out humidification in refrigerator, foul smell becomes the time dependent curve of component.Naturally the decay of methyl mercaptan in the 16 expression refrigerators, the situation when 17 expression refrigerators are in drying, the situation of change during 18 expression humidification refrigerators.As can be seen from Figure 4, the occasion 18 during humidification can improve deodoriging properties.
This situation is thought because methyl mercaptan absorbs moisture, has improved deodoriging properties on apparent.Think as reason, the moisture of blower fan surface absorption be not resemble the water-sprinkling a lot, all frostings on cooler of the most of moisture in the refrigerator, the moisture of the frosting of only failing could arrive blower fan, therefore, the moisture that is adsorbed on the blower fan is less relatively.In addition, the steam that reaches in the cold air of blower fan becomes fine water droplet dewfall on the blower fan surface, and these water adsorption can be used for the regeneration of polyphenol on the blower fan surface, and therefore, the blower fan surface can not iced in large area to be covered.
Also have, consider, the necessary moisture and insufficient of regenerating owing to the most of moisture frosting on cooler in the refrigerator, frosting on the fusing cooler, when carrying out Defrost operation, the steam of the moisture after the fusing can be adsorbed on the blower fan surface, fully carries out the regeneration of deodorizing capability.Like this, repeated regeneration can recover performance antibiotic, deodorizing, and can its performance of long term maintenance, carries out antibiotic, deodorizing in the refrigerator.
Below, with the suitable scope of table 1 explanation polyphenol addition.It is generally acknowledged that the polyphenol addition is many more, deodoriging properties is good more, and still, this can reduce the intensity of plastics, therefore thinks to have the scope that is fit to.The result of study that changes green tea composition addition is as shown in table 1, adds 20% when above, and intensity decline is inappropriate as the blower fan of cooling device.Also have, too much improve addition, will increase cost.Therefore, carried out the research of deodoriging properties and addition.Show with the comparative studies result of the deodorizing sheet of well-known polyacrylic resin type, when the mentioned component content in the green tea 5% when above, can surpass existing deodorising product.According to above result of study, think the green tea composition addition more than 5% and 20% below be suitable.
The OK range of table 1 polyphenol addition
| The addition of deodorant (%) | 1 | 5 | 10 | 15 | 20 | 25 | 30 |
| Intensity | ○ | ○ | ○ | ○ | ○ | × | × |

According to the above embodiments, can suppress the increase of circulating cold air resistance, and improve deodorizing, anti-microbial property.Give pressure fan with deodorizing, antibiotic function, so, carry out deodorizing, antibiotic parts itself can gather foul smell, make the antibiotic possibility that becomes of efficient deodorizing.Also have, the material that plant is contained also can improve the grade of goods as deodorizing, antibiotic composition.In addition, constitute the material of blower fan, can bring into play the deodorizing of fan part inside, the effect of anti-biotic material effectively owing to contain glass.
Compositions such as tea powder, tea extraction, tea phenol, tea saponin have good antibacterial property, as contain in the plant can be antibiotic composition known, and, have very high security.Therefore, can possess the wholesomeness and the security of cooling device simultaneously.
Also have, the mechanism that the absorption odorous substance carries out deodorizing is with chemical reaction decompose odor composition, therefore, can not store up the foul smell composition at deodorisation process.Therefore, deodorizing is infallible, can its performance of long term maintenance, and can use for a long time.
The present invention also adopts cheap structure, utilizes the moisture in the cold air to make the regeneration of deodorizing antibiotic ability, like this, obtains carrying out a large amount of foul smell the refrigerator of deodorizing.
As mentioned above, the present invention can provide the cooling device that cooling effectiveness improves.
The cooling device that can carry out deodorizing or antibacterial action for a long time can also be provided.
