In addition, in above-mentioned existing structure, because the mode according to returning of cold air stopped up in wind path configures odor removal filter, sterilizing filter, so they form larger wind path impedance in the circulating path of cold air.Therefore, if will obtain the cooling performance identical with the state that there is no filter, need to improve the ability of the fan 10 for making the cold air forced circulation.
But the ability of raising fan, can cause the increase of noise, and violate energy-conservation principle, is not desirable scheme.
Summary of the invention
The present invention completes in view of the above problems, and its purpose is to provide a kind of freezer that can obtain expeditiously the effect of degerming and deodorizing.
Particularly, the object of the present invention is to provide the pressure loss in a kind of circulating path that can suppress as far as possible cold air, simultaneously at the freezer of the effect that obtains in a big way deodorizing and degerming.
In addition, the present invention also aims to provide a kind of cold air to blowing out in storehouse not smelly, the repressed clean freezer of the breeding of miscellaneous bacteria.
The inventor finds, in the temperature of storeroom, is setting when following, and in the freezer stopped at the fan that makes circulating cold air, the cold air after degerming is difficult to spread all over whole storeroom.

Then, bactericidal device 200 is described.
Figure 20 means the stereogram of the bactericidal device 200 under the state that is installed on freezer 100 of embodiment 7.
Basic structure and the function of the bactericidal device 200 of present embodiment, with using, Fig. 9 basic structure and function explanation, bactericidal device 200 embodiment 3 are identical, also possess in addition the ventilation fan 220 that carries out forced ventilation.
Then, illustrate the installation pattern of bactericidal device 200 to freezer 100.
Figure 21 (a), Figure 21 (b) and Figure 21 (c) mean the sectional view of installation pattern of the bactericidal device 200 of embodiment 7.
As shown in Figure 20, Figure 21 (a)～Figure 21 (c), in the upper end of refrigerating chamber 102, be between outlet 130, be provided with the depressed part 203 that front has mouth.Depressed part 203 is arranged at the place ahead of the step-like recess 113 that compressor 114 grades are installed.
This part, for not forming the idle space of accommodation space, by be provided for installing the depressed part 203 of bactericidal device 200 in this part, thereby can not wasted the accommodation space in refrigerating chamber 102, and bactericidal device 200 can be installed.
In addition, the substance of the installation pattern of bactericidal device 200 is with identical in embodiment 3, as used the illustrated content of Figure 10 (a).
But, in the bactericidal device 200 of present embodiment, possess ventilation fan 220.Particularly, the end edge portion at cap assembly 205 configures the ventilation fan 220 as ventilation mechanism.Ventilation fan 220 consists of the suction fan 221 of the cold air in the interior pressure importing of bactericidal device 200 refrigerating chamber 102.
About the freezer 100 of the embodiment 7 that forms as mentioned above, below its action of explanation, effect.
In addition, about the action of freeze cycle, because the action of the freezer 100 with embodiment 1 is identical, therefore the description thereof will be omitted, function and the effect thereof of bactericidal device 200 described.
The function of the bactericidal device 200 of present embodiment and effect thereof are basically identical with the function and efficacy of the bactericidal device 200 of above-mentioned embodiment 3.That is, the cold air passed through in bactericidal device 200 becomes by the clean cold air of deodorizing, degerming, via intercommunicating pore 207, in storehouse, blows out.Then mix with the cold air of discharging from outlet 130 in refrigerating chamber 102 inside, circulate in circulating path.
But the bactericidal device 200 of present embodiment, stop at cooling fan 121, under the state that cold air does not circulate in the circulating cold air path with discharge line 129a etc. at refrigerating chamber, as shown in Figure 21 (b), ventilation fan 220 actions.
Thus, by being changed by the pressure of the cold air of degerming in the cold air in refrigerating chamber 102 and bactericidal device 200.That is, to containing in the space that holds body 201 and irradiation means 202 He in storeroom, carry out forced ventilation.
In addition, by suction, fan 221 forced convertions at the interior generation cold air of refrigerating chamber 102 (circulation), the cold air that the degerming of discharging from bactericidal device 200 completes spreads all in refrigerating chamber 102.
Thus, even in the situation that cooling fan 121 stop, owing to being spread by the cold air of degerming by compulsory convection current (circulation) in refrigerating chamber 102, so refrigerating chamber 102 can be maintained to clean state.
In addition, in the above-described embodiment, ventilation fan 220 consists of the suction fan 221 of the cold air in the interior pressure importing of bactericidal device 200 refrigerating chamber 102, but the present invention is not limited to this.
For example, as shown in Figure 21 (c), ventilation fan 220 also can consist of the discharge fan 222 of the cold air in the interior pressure discharge of bactericidal device 200 refrigerating chamber 102.
Utilize this discharge fan 222, the discharge wind speed of the cold air that the degerming in bactericidal device 200 is completed increases, forced convertion (circulation) at refrigerating chamber 102 interior cold air increases, and the cold air that the degerming of discharging from bactericidal device 200 completes easily spreads all in refrigerating chamber 102.Therefore, can further improve degerming, the function of deodorizing.
Freezer of the present invention possesses: consist of heat-barrier material, form the heat insulating box of storeroom in inside; Open and close the door body of the peristome that is installed on freely heat insulating box; Air in cooling heat insulating box generates the cooling body of cold air; And between storeroom and above-mentioned cooling body the circulating cold air path of circulation cold air, there is the bactericidal device be configured in storeroom in this freezer, this bactericidal device has and holds holding body and holding to above-mentioned the irradiation means that body irradiates the exciting light of exciting light catalyst of photochemical catalyst, and bactericidal device has the ventilation mechanism of forced ventilation in storeroom and in bactericidal device.
Thus, even in the situation that freezer does not make circulating cold air, be forced to circulation due to the cold air in bunker in by deodorizing and degerming, so it is interior in a big way to make deodorizing and bacteria-eliminating efficacy relate to freezer, can in freezer, maintain low smelly, degerming state.
Like this, freezer of the present invention is not vulnerable to the anti-impact of wind path, although configure bactericidal device in storeroom, still can maintain the cycle efficieny of cold air, even and when do not carry out the circulation time of cold air in the circulating cold air path, bactericidal device self also can make circulating cold air, makes bacteria-eliminating efficacy spread all over storeroom.
Freezer of the present invention is owing to can making bacteria-eliminating efficacy spread all over storeroom, so the high-quality freezer that bacteria-eliminating efficacy is further improved can be provided.
(embodiment 8)
Then, use Figure 22～Figure 29 that embodiments of the present invention 8 are described.
In addition, the basic structure of the freezer 100 of embodiment 8 is identical with the freezer 100 of embodiment 3, and the description thereof will be omitted.
At this, in embodiment 3, as shown in Fig. 8 waits, bactericidal device 200 is arranged in refrigerating chamber 102.But, bactericidal device 200 place is set so long as get final product in the circulating cold air path, be not limited in refrigerating chamber 102.
In addition, a plurality of light sources 132 and the position relationship held between body 201 also are not limited to the position relationship shown in Fig. 9, also exist and are positioned under other position relationships and the advantageous effects caused.In addition, also exist for improving the degerming of bactericidal device 200 and the method for deodorizing effect.
Therefore, in embodiment 8, about setting position of bactericidal device 200 etc., illustrate and there is no in other embodiments illustrative concrete example.
For example, in freezer 100, also bactericidal device 200 can be arranged in the pipeline of a part that forms the circulating cold air path.Owing to being the place that is not vulnerable to the impact of extraneous gas with comparing in storeroom in pipeline, so there is the LED substrate and hold body 201 and be difficult for dewfall.
Figure 22 (a), Figure 22 (b) and Figure 22 (c) mean the figure that in embodiment 8, bactericidal device 200 is arranged on to the example of the setting position in the situation in pipeline.
For example, as shown in Figure 22 (a), also can bactericidal device 200 be set near the position of cold air left and right branch in discharge line 129a at refrigerating chamber.By bactericidal device 200 is arranged on to this place, by the cold air of degerming and deodorizing from the outlet 130 of left and right equably to the interior discharge of refrigerating chamber 102.
In addition, for example, as shown in Figure 22 (b), also can bactericidal device 200 be set near with the outlet 130 in discharge line 129a at refrigerating chamber.By bactericidal device 200 is arranged on to this place, thus can be at the cold air in freezer 100 interior circulations to degerming and the deodorizing of carrying out cold air before blowing out in refrigerating chamber 102.That is, clean cold air can be blown out in refrigerating chamber 102.
In addition, in Figure 22 (a) and Figure 22 (b) setting party of bactericidal device 200 to be hold body 201 in front and irradiation means 202 in direction inboard or in contrast, but can not be also such setting party to.
For example, as shown in Figure 22 (c), also can to hold body 201 in left side, the mode of irradiation means 202 on right side arranges bactericidal device 200.Perhaps also can hold the mode of body 201 on right side in left side with irradiation means 202 bactericidal device 200 is set.
That is, the setting position of bactericidal device 200 in pipeline needs only the suitably decisions such as size and dimension according to pipeline.For example, bactericidal device 200 also can not be arranged on refrigerating chamber with in discharge line 129a, but is configured in refrigerating chamber Returning pipe 129b.
In addition, in Figure 22 (b) and Figure 22 (c), only near the outlet 130 in left side, dispose bactericidal device 200, but also can only the outlet 130 on right side near, configure bactericidal device 200.In addition, also can two sides configure bactericidal devices 200 in left and right.
Above, use Figure 22 (a)～Figure 22 (c) that the example that bactericidal device 200 is configured in to the allocation position in the situation in pipeline has been described.
At this, bactericidal device 200 is owing to having the irradiation means 202 of to holding body 201, irradiating exciting light, so, in situation about being arranged in refrigerating chamber 102, also play as mentioned above the function as the illumination in refrigerating chamber 102.
In addition, when bactericidal device 200 is arranged in the situation in pipeline, as mentioned above, there is the effect of the generation of the dewfall that suppresses the LED substrate and hold body 201.
Therefore, by a part in a plurality of light sources 132 that only bactericidal device 200 had, be accommodated in pipeline, other part light sources are configured on the position that can irradiate in refrigerating chamber 102, thereby can make bactericidal device 200 carry out degerming and the deodorizing of cold air in the generation that suppresses dewfall, and can play the function of the illumination of refrigerating chamber 102.
Therefore, next illustrate with in a plurality of light sources 132 only a part be present in pipeline, other light sources 132 is present in the situation that the mode of irradiating the position in storeroom arranges bactericidal device 200.
Figure 23 means in a plurality of light sources 132 of embodiment 8 that a part only is present in the figure of example of the setting position of the bactericidal device 200 in the situation in pipeline.
Particularly, as shown in the sectional view on the right side of Figure 23, the LED substrate is crossed over refrigerating chamber and is existed with the inside and outside of discharge line 129a, and two light sources 132 in three light sources 132 are present in refrigerating chamber use discharge line 129a.Hold body 201 in the position configuration relative with these two light sources 132.
In addition, an outer light source 132 is configured on the position that can irradiate in refrigerating chamber 102 with discharge line 129a to be present in refrigerating chamber, in the inner wall section of the refrigerating chamber 102 in the front of this light source 132, is provided with transparent luffer boards 209.
As mentioned above, bactericidal device 200 has a plurality of light sources 132.Particularly, adopt LED as light source 132.Therefore, also can make the brightness difference of each light source 132, make to hold body 201 and be configured on the position that the light source high with brightness 132 is relative.
Thus, can realize the long lifetime of the low light source of brightness 132, and can make the bacteria-eliminating efficacy based on holding body 201 effectively actual.
In addition, even the low light source 132 of brightness in the situation that can not fully carry out exciting of catalyst, also contributes to hold the rising of the atmosphere temperature around body 201, can bring into play the effect of the generation that suppresses dewfall.
The figure that Figure 24 is embodiment 8, high light source 132 is configured in the structural outline of the bactericidal device 200 in the situation of central authorities of row of light source 132 by brightness.In addition, the bactericidal device shown in Figure 24 200 is configured in the top (with reference to Fig. 8) in freezer 102 in the identical mode of freezer 100 with embodiment 3.
As shown in figure 24, in the row that consist of a plurality of light sources 132, the light source 132 that brightness is high is configured in central authorities.The body 201 that holds of width that in addition, will be narrower than the width of these row is configured near the position relative central authorities with these row.
Thus, bactericidal device 200 forms symmetrical structure as shown in figure 24.
That is,, by configuring like this plurality of light sources 132 and holding body 201, on the basis of above-mentioned effect, can also in the situation that from the left and right both sides, bactericidal device 200 is blown into to cold air, will carry out degerming from both sides' cold air expeditiously.
These light sources 132 in addition, because not existing, the front of the low light source 132 of the brightness in left and right do not hold body 201, so can be brought into play the function as the illumination in refrigerating chamber 102 better.
For example, in the situation that hold on body 201, as catalyst, be carried with titanium oxide, the ultraviolet light source 132 that produces black light be configured near the central authorities of row of light source 132.In addition, beyond the light source 132 that produces visible ray being configured near central authorities.
While using Figure 24 that above-mentioned configuration is described, in the central configuration of these row, produce ultraviolet light source 132, produce the light source 132 of visible ray in its left and right configuration.
In addition, in the position configuration relative with producing ultraviolet light source 132 width shorter than the width of these row of light source 132 hold body 201.
Thus, the light source 132 of central authorities can excite the titanium oxide that is held body 201 and hold, and simultaneously, the light source 132 of left and right can play the function as the illumination in refrigerating chamber 102.
Figure 25 mean embodiment 8, by brightness, low light source 132 is configured in the figure of the structural outline of the bactericidal device 200 in the situation of central authorities of row of light source 132.In addition, the bactericidal device shown in Figure 25 200 is configured in pipeline.
As shown in figure 25, in the row that consist of a plurality of light sources 132, the light source 132 that brightness is low is configured in central authorities.In addition, width that will be narrower than this column width hold body 201 be configured in central authorities except these row near relative position, position on.That is, hold body 201 and be configured in the position that the light source high with brightness 132 is relative.
By configuring like this plurality of light sources 132 and holding body 201, as shown in the figure, can be used in the central authorities that the allocation position that will hold body 201 and be arranged on the screw 216 in freezer 100 is arranged at bactericidal device 200.
That is, by configuring like this plurality of light sources 132 and holding body 201, thereby on the basis of above-mentioned effect, can also balance well and will hold body 201 with a small amount of parts and for example be arranged in pipeline.
In addition, have two and hold body 201 in Figure 25, but holding body 201 can be also any one.In this case, only the light source 132 relative with holding body 201 has high brightness and gets final product.In addition, shown in also can formation figure will have two hold body 201 in conjunction with after the central authorities that hold body 201 of degree size near be arranged on the structure of inner-walls of duct etc. by screw 216.
In Figure 24 described above etc., to hold body 201 substantially vertical with respect to flat for the direction of illumination of the exciting light of light source 132.But light source 132 also can be from irradiating exciting light with respect to holding body 201 from the direction tilted.
The direction of illumination of the exciting light that Figure 26 is embodiment 8 (is meaned by chain-dotted line.In the situation that Figure 27 is with identical in Figure 28) with respect to holding the light source 132 that body 201 is vertical and the allocation plan that holds body 201.
Particularly, in Figure 26, bactericidal device 200 is arranged in the pipeline that width is W.In addition, clear in order to make to illustrate, show a light source 132 in figure and hold the position relationship of body 201.
At this, the feature of light source 132 for example has its projecting direction as mentioned above to have directive property, and illumination angle is narrower and small.Therefore, as shown in figure 26, under making light source 132 and holding the relative situation about being configured in the narrow and small pipeline of width of body 201, can not be controlled at irradiation area by all holding body 201.
Particularly, light source 132 only can be to the flat face (following also referred to as " interarea ") that holds the maximum area of body 201, be the area illumination exciting light that is less than the regulation zone that holds the upper surface of body 201 in Figure 26.
In addition, when like this in the situation that the direction of illumination that maintains exciting light when holding state that body 201 is vertical and widen irradiation area, the distance that can consider to increase light source 132 and hold body 201.But can not guarantee so long distance in pipeline.
In addition, no matter whether in pipeline, owing to increasing light source 132 and holding the distance between body 201, exciting light is reduced to the stimulation effect of catalyst.
Therefore, as shown in figure 27, the mode of irradiating exciting light according to the direction from respect to holding body 201 inclinations configures light source 132.
Figure 27 is direction of illumination embodiment 8, that make exciting light with respect to holding the light source 132 in the situation that body 201 tilts and holding the allocation plan of body 201.
Particularly, make the light source 132 as irradiation means, be arranged at the direction that the direction of illumination of exciting light can not become vertical towards the interarea with respect to holding body 201, and beyond the central authorities of this light source 132 and interarea on relative position.
Thus, no matter whether with Figure 26, coexist mutually in the pipeline of width W and be provided with light source 132 and hold body 201, the Zone Full of interarea can both be controlled in irradiation area.
In addition, the distance of the right-hand member that holds body 201 of Figure 27 and light source 132 is than this distance in the situation shown in Figure 26.But light source 132 is roughly the same with the beeline and the situation shown in Figure 26 that hold body 201, can not make to excite the effect of catalyst significantly to reduce.
In addition, due to the ratio raising of light area in the surface area that holds body 201, so improve as the degerming that holds body 201 integral body and deodorizing effect.
In addition, in Figure 27, the mode be controlled at according to the Zone Full of interarea in the irradiation area of light source 132 configures light source 132.But, light source 132 also can be set and make the requirement ratio of interarea above, for example be controlled in irradiation area more than 80%.
In addition, for example also can determine with the benchmark more than 40% of the surface area that holds body 201 that light source 132 is with respect to the position that is oppositely arranged that holds body 201.
That is, as long as be configured to as shown in figure 27 in the situation that light source 132 is set obliquely, with the situation of as shown in figure 26 interarea vertically being irradiated to exciting light, compare, by holding zone wider in the surface area of body 201, be controlled in irradiation area and get final product.
In addition, in Figure 27, about a light source 132, be illustrated, but be controlled in the irradiation area of these light sources more than the requirement ratio that a plurality of light sources 132 make interarea also can be set.
For example, also can hold body 201 with respect to one, irradiate obliquely respectively exciting light from two light sources 132, thereby the Zone Full of interarea is controlled in irradiation area.
In addition, in the present embodiment, hold body 201 for tabular, be the rectangular shape of thin thickness.Therefore, as area, large face is interarea in concern, by interarea being irradiated to more exciting light, realizes the raising of degerming and odor removal efficient.
But, sometimes also to consider to hold the face beyond the interarea of body 201, the face all around that in Figure 27, holds body 201 situation that namely area of side can not be ignored in the exciting of photochemical catalyst.That is, also to be considered as the flat thicker situation of Thickness Ratio that holds body 201.
In this case, also can configure more than one light source 132 makes interarea and each side be controlled in irradiation area.In addition, in the situation that in Figure 27, the interarea of serving as the lower surface that holds body 201 is also irradiated to exciting light, also can be configured for the light source 132 that this interarea is irradiated to exciting light.
In addition, in Figure 27, illustrate bactericidal device 200 is arranged on to the situation in pipeline.But, as long as light source 132 and the relative position relation that holds body 201 are the position relationship shown in Figure 27, no matter the setting position of bactericidal device 200, for where, can both be brought into play expeditiously the effect of degerming and the deodorizing of cold air in narrow space.
At this, for example, as shown in figure 27, light source 132 be positioned at the top, hold body 201 be positioned at the below situation under there is peculiar effect as described below.
That is: in the situation that holds body 201 dewfall, its water droplet can not flow into the LED substrate, can maintain the reliability of bactericidal device 200.
In addition, as shown in figure 28, when light source 132, in below, hold in the situation of body 201 in top and there is distinctive effect as described below.
Figure 28 is that the direction of illumination that makes exciting light tilts with respect to holding body 201, and in light source 132 under, hold body 201 in the situation that the light source 132 of upper upper and lower relation and hold the allocation plan of body 201.
Like this, by configuration, as the light source 132 of irradiation means with hold body 201, be used to the free convection that the heating from light source 132 causes, can effectively suppress to hold the generation of the dewfall of body 201.
(concrete example of the method that degerming and deodorizing effect are improved)
Hold body 201 as mentioned above for rubbing the structure of the filtration shape formed into the fiber entanglement that photochemical catalyst is arranged, the resin that adopts the light of easy exciting light catalyst to see through as the resin of base material.
That is: certain ratio that holds the exciting light that body 201 irradiates is seen through and holds body 201.Therefore, bactericidal device 200 also can possess the exciting light reflection that projection is held to body 201, makes it to the reflecting plate that holds body 201 incidents.
Thus, can improve degerming and the deodorizing effect of 200 pairs of cold air of bactericidal device.
Figure 29 (a) and Figure 29 (b) mean embodiment 8 reflecting plate 215 setting example and by the figure of the situation of reflecting plate 215 reflection exciting lights.
As shown in Figure 29 (a), clip and hold body 201, at the opposition side of irradiation means 202, reflecting plate 215 is set.
In addition, the raw material of reflecting plate 215 particularly, so long as mirror or metallic plate etc. can reflect the raw material of exciting light gets final product, are not limited to specific raw material.
Thus, as shown in Figure 29 (b), from light source 132, irradiate through the exciting light that holds body 201 and be reflected plate 215 reflections, again incide and hold body 201.
Therefore, with the situation that there is no reflecting plate 215, compare, can excite expeditiously the catalyst that is held body 201 and hold, improve degerming and odor removal efficient.
In addition, in Figure 29 (a) and Figure 29 (b), hold the setting that adjoins each other of body 201 and reflecting plate 215.But, also can separate setting with reflecting plate 215 by holding body 201.
That is, hold the interval of body 201 and reflecting plate 215 so long as can make to see through the exciting light that holds body 201 and be reflected plate 215 reflections, again incide the distance that holds body 201 and get final product.
