Although the measures of the existing freezing and refrigeration refrigerator considers arranging deodorization device in the cold air channel to eliminate the stench in the circulating cold air and thereby reducing the stench, there is no air current flowing between the foods and the stench component which is heavier than the air resorts, the circulating amount of the cold air needs to be increased to increasing to reduce the stench in the refrigerator with the deodorization device arranged in the cold air circulating air duct and therefore it exists the problem that the food is accelerated to dry. The technical project of the invention is as follows, the character of the refrigerator where the cold air cooled by the cooler is forced to circulate in the refrigerating room using the cold air circulating fan and the like air feeding mechanism is that it does deodorizing machining to the resin part which contacts the food.

Description

Refrigerator

Technical field

The present invention relates to refrigerator, especially prevent to be full of the refrigerator of the foul smell that from the food of storage, produces.

Background technology

Commercially available refrigerating and cold storage refrigerator has odor removal in order to prevent to be full of the foul smell that produces from the food of storage in cold air channel.This is as described in the patent documentation 1-TOHKEMY 2003-50079 communique.

Existing refrigerating and cold storage refrigerator is as the measure of eliminating the stench in the refrigerator, thereby considered that the stench of removing in the circulate cold air by configuration odor removal in cold air channel can reduce foul smell.This is because because existing refrigerating and cold storage refrigerator can be preserved the food in each corner with the chilled air cools of this circulation, thereby can think that the air circulation in the refrigerator has arrived each corner.

But, a large amount of in store food in the refrigerator.Therefore, the main current flow of cooling blast is crossed the empty space on food top, and the air-flow that flows through between food and food etc. is few.However, why can cool off the food that is housed in the refrigerator at large, be because warm air is lighter than cold air, when the air in the empty space of having cooled off food top passes through, cold air descends naturally, and the warm air between food and the food rises naturally, thereby is cooled to each corner.On the other hand, because the odor pollutant of refrigerator nearly all is heavier than air, thereby in existing cold air endless form, even warm air rises, the foul smell composition still continues to be trapped between food and the food.

In order to address this problem, be necessary to strengthen the internal circulating load of quickening cold air, even there are a large amount of food also to allow air-flow can arrive each corner.But so, moisture is seized by near the cold air the food again, has promoted the drying of food.Though general food has all added preservative film,, also promote drying even added preservative film because of preservative film sees through moisture.

In addition, in the storeroom that has used container dark as vegetable compartment, because cold air has cooled off food equably by the outside circulation of container.Therefore, owing to there is not the cold air circulation in the container, stench does not circulate.

Therefore, as desirable store method, must come the foul smell between food and the food is carried out deodorizing with the minimum cool air circulation amount that generally turns cold and with the cold air of convection current.

Summary of the invention

The object of the present invention is to provide a kind of refrigerator that the dry of food can be suppressed with the MIN cool air circulation amount of necessity and prevent the stench in the refrigerator.

To achieve these goals, the refrigerator of the 1st scheme of the present invention is characterised in that, make in the refrigerator of the chilled cold air of the device that is cooled forced circulation in refrigerating chamber at wind pushing mechanisms such as using cool air circulation fan, the resin part with Food Contact has been carried out deodorizing processing.

In addition, the zone as refrigerating chamber 3 expressions is divided into ice-making compartment 3a, quick-frozen chamber 3b and refrigerating chamber 3c, these several indoor temperature that remain on the cryogenic temperature band respectively.Have automatic ice-making plant and storage ice container in the ice-making compartment 3a, storage ice container is made the structure that pulls out with door by pulling out drawer type door.In addition, quick-frozen chamber 3b and refrigerating chamber 3c also respectively by the peristome of whole of drawer type door sealing, make the structure of pulling out internal container by the door of pulling out refrigerator.

Particularly refrigerating chamber 3c has held three containers up and down as shown in the figure, is respectively equipped with lower floor's refrigerating chamber container 5, middle level refrigerating chamber container 6, upper strata refrigerating chamber container 7 from the lower floor to the upper strata.Though not shown, lower floor's refrigerating chamber container 5 and middle level refrigerating chamber container 6 are fixed on pulling out on the frame of refrigerating chamber door, and with the switching of this refrigerating chamber door interlock in the refrigerating chamber 3c that comes in and goes out.Upper strata refrigerating chamber container 7 is made the guide rail that can utilize on the inner box side face that is arranged at the sidewall that constitutes refrigerating chamber 3c and the structure of pulling out with respect to refrigerating chamber 3c.Have, each container 5,6,7 is the mutually different container of depth dimensions, is suitable for the different food of folding and unfolding various sizes again.

Below, illustrate by the situation in the chilled air cools refrigerating chamber 3 that generates by the cooler chamber 8 at the back that is formed at above-mentioned refrigerating chamber 3 among Fig. 2.

Label 8 is the cooler chambers that are formed at the back of refrigerating chamber 3, is provided with the cooler 9 and the cool air circulation fan 10 that constitute freeze cycle in this cooler chamber 8; This cool air circulation fan 10 is used to make the cold air forced circulation that is generated by cooler 9 self-evident by refrigerating chamber 3, but also passes through refrigerating chamber 2, vegetable compartment 4 via valve 11.

Label 12 is the isolated part assemblies that separate between refrigerating chamber 3 and the cooler chamber 8.On this isolated part assembly 12, as shown in Figure 3, be provided with and be used for and deliver to the outlet of each container portions via the cold air of cooler 9.Promptly, the cold air of being sent by cool air circulation fan 10 is sent to ice-making compartment 3a, quick-frozen chamber 3b and refrigerating chamber 3c respectively through outlet, especially the refrigerating chamber 3c of three layers refrigerating chamber container about having disposes the outlet of cold air being supplied with each refrigerating chamber container respectively.

In addition, the structure of the back side one side of this isolated part assembly 12 is, assembled cool air circulation fan 10, valve 11 etc. in advance, and is installed to the back of refrigerating chamber 3 in the mode that the front side from refrigerator main body covers cooler 9.

These containers make cold air enter into wherein structure from the top of container by the cold air outlet at the back side owing to make, thereby the air-flow that is produced in the gap of the food of stacking in container are few as shown in Figure 2.

In the present embodiment, parts and container in the above-mentioned refrigerator self have been carried out deodorizing processing processing and made it have deodorization.The cold air that is sent in the refrigerating chamber 2 is less with its cold air amount of cold air comparison that is sent to refrigerating chamber 3, and air-flow is stable generally.But, handle because parts in the refrigerator and container have been carried out deodorizing processing, thereby can expect and realize deodorization in the refrigerating chamber 2.For container, it is effective at least deodorizing processing being carried out in the inboard of preserved food products.

In addition, even in the folding and unfolding container of the refrigerating chamber 3 of the overlapping stacking of food and vegetable compartment 4, though the provision room in the folding and unfolding container is difficult to produce flowing of cold air, because having been carried out deodorizing processing, handles by container, can expect and can realize deodorization in refrigerating chamber 3, the vegetable compartment 4.

Deodorant is the material that contains zinc, silver, silica at least, the mixing composition that generates zinc oxide ion and silanol ion in the resin part that detachably cleans.In addition, having coated average grain diameter at least on the transparent resin part is the Titanium particles of 1nm～100nm.

Below, the deodorizing result of the employed deodorant of container of the present invention is described.

Fig. 5 is illustrated in and has added the deodorant that generates zinc oxide ion and silanol ion in the acrylic resin, mounting cover and make it airtight in type container, filled methyl mercaptan therein, and measured the result of the decay of the methyl mercaptan concentration in the container with stench.Label 13 is the containers that do not add deodorant, the 14th, added the container of deodorant, the 15th, the container that does not add deodorant after cleaning, the 16th, the interpolation after cleaning the container of deodorant.

According to the result who measures as can be known, the odor concentrations that added in the container 14 of deodorant reduce, by having deodorizing effect with deodorant is mixing in resin.In addition, according to the result of the recovery situation of after the container behind the deodorizing test is cleaned, measuring deodorizing capability again as can be known, the interpolation after the cleaning odor concentrations in the container 16 of deodorant reduce, recover by cleaning deodorizing capability.

In addition also as can be known, for the container that does not add deodorant, even through cleaning, the concentration of methyl mercaptan is not decay immediately also, and the effect of having added deodorant is obvious.

Fig. 6 represents from being that the container of the Titanium particles of 1nm～100nm cuts the square test film of 10cm coated average grain diameter with transparent polystyrene resin container for moulding, put in the sampling bag (テ De ラ バ Star Network) of 3L and carry out airtight, filled methyl mercaptan therein and placed after 24 hours, measured the decay of the methyl mercaptan concentration in the bag and utilized the concentration result of the dimethyl disulfide that light-catalyzed reaction generates with stench.Label 17 is residual rates of the methyl mercaptan in the sampling bag, the 18th, and the production rate with respect to theoretical value of the dimethyl disulfide that is generated when utilizing light-catalyzed reaction to decompose methyl mercaptan.

The result of test shows, with the residual rate reduction of preliminary phase than methyl mercaptan after 24 hours, thereby has realized deodorizing.This is because foul smell is adsorbed on the deodorizing coating film and further decomposes by light-catalyzed reaction.And even do not having also to generate the dimethyl disulfide as decomposition product under the state of irradiates light, hence one can see that, also can carry out light-catalyzed reaction even without light.Show also that in addition if improve temperature, the residual rate of methyl mercaptan reduces, the production rate of dimethyl disulfide improves.This is because owing to increase by the decomposition amount of light-catalyzed reaction, correspondingly adsorbance also increases.Hence one can see that, can further promote light-catalyzed reaction by heating.Therefore, use hot water to clean when cleaning the refrigerator parts, decomposition is adsorbed on odor pollutant on the deodorizing coating film, it is more effective recovering its deodorizing capability.

According to the foregoing description, has following effect.Promptly, make in the refrigerator of cold air forced circulation in refrigerating chamber of the device cooling that is cooled at wind pushing mechanisms such as using cool air circulation fan, by the resin parts with Food Contact being carried out deodorizing processing, can carry out deodorizing to the foul smell that is trapped between food and the food, under will be, can not feel peculiar smell the empty state of food storage in the refrigerator.In addition, do not allow foul smell be stuck between food and the food owing to do not need to increase cool air circulation amount, thereby, can not promote the drying of food, and can keep not having the interior space of refrigerator of peculiar smell.In addition, by the mixing composition that generates zinc oxide ion and silanol ion in the detachable resin part that cleans, wash with water and can regenerate, therefore sustainable deodorizing capability.By coated average grain diameter on the transparent resin part is the Titanium particles of 1nm～100nm, can not damage transparency and can add deodorization functions, and the photoactivation reaction can also continue deodorizing capability.

Particularly in cool air circulation amount fewer refrigerating chamber and vegetable compartment, the refrigerating chamber of dark folding and unfolding container and vegetable compartment etc. perhaps are installed have the tendency that the foul smell composition is stagnated easily, therefore if parts in the refrigerator and container are carried out the deodorizing processing, then can carry out deodorizing effectively.
