In addition, holding the contained above-mentioned photochemical catalyst of holding of body in above-mentioned year can contain silver, and above-mentioned irradiation means has light source, above-mentioned light source with wavelength greater than 400nm and held body as above-mentioned exciting light to above-mentioned year smaller or equal to the light of 520nm and shine.
Thus, when the non-irradiation of the running of device when stopping, light, have the antibiotic property that causes by silver, in addition, when the running of device, during the irradiation of light, can improve silver-colored antibacterial activity by light.Thus, can bring into play higher antibiotic property.And, by the restriction light wavelength, can provide not make the resinae deterioration, to human body safety and low-cost bactericidal device.
In addition, can in above-mentioned heat insulating box, be formed with a plurality of storerooms, held body and above-mentioned irradiation means in above-mentioned year and be configured in the stream of the above-mentioned cold air that storeroom is discharged, above-mentioned storeroom is included in the back segment of the initial storeroom that passes through of cold air that is generated by above-mentioned cooling body.
Thus, bactericidal device diminishes to the influence of the wind path impedance in the circulating cold air path.Therefore, can on the basis of the cycle efficieny of keeping cold air, carry out deodorizing, degerming to being positioned at from second later storeroom on the cold air flow direction of cooling body.
In addition, cold air is along with leaving from cooling body, and its temperature uprises.When producing dewfall etc. at storeroom, then be unfavorable on the visual perception, but since second later storeroom than first storeroom temperature height, so be difficult to dewfall.Therefore, second later storeroom can keep the state of visual perception's coideal, we can say to cause that the discontented possibility in market is little.
In addition, freezer of the present invention can also possess ventilation mechanism, and it will contain in the space of holding body and above-mentioned irradiation means in above-mentioned year Yu in the above-mentioned storeroom and carry out forced ventilation.

In addition, above-mentioned irradiation means had light emitting diode, and above-mentioned light emitting diode was held body and shone above-mentioned exciting light from the direction that tilts with respect to above-mentioned year.
Light emitting diode has directive property and has the narrower and small feature of illumination angle, by holding body and shine exciting light obliquely with respect to carrying like this, can not increase light emitting diode and carry degerming and the deodorizing of carrying out cold air in the less space of the distance of holding body expeditiously.
In addition, hold body and above-mentioned irradiation means in above-mentioned year and be configured in the inside of the bactericidal device that above-mentioned freezer possesses, above-mentioned freezer also has the lateral of formation from the individual path of above-mentioned circulating cold air path branches, above-mentioned bactericidal device is connected with above-mentioned lateral, possesses the intercommunicating pore that makes the cold air that flows into above-mentioned bactericidal device return above-mentioned circulating cold air path.
Like this, make the pipe special of a part of branch of the cold air of circulation by setting, can suppress the generation of wind path impedance of the main flow of circulating cold air, can not consider the wind path impedance of main flow and improve to be designed for and make cold air contact the free degree of carrying the lateral of holding body expeditiously.Consequently, the increase of wind path impedance can be suppressed, the effect of deodorizing and degerming can be improved simultaneously.
In addition, held the position that circulating direction that body is configured in above-mentioned cold air in the above-mentioned circulating cold air path changes in above-mentioned year, held body and be configured in above-mentioned year according to the mode that the part parallel with the circulating direction of the above-mentioned cold air of holding body towards above-mentioned year is contained in the normal of the big face of area.
By like this, deodorizing and bacteria-eliminating efficacy are related in the freezer in a big way, can maintain low smelly, degerming state in the freezer.
Particularly, because the variations in flow of the cold air in the position wind path of the circulating direction of changing cold air produces turbulent flow, so hold body by disposing to carry according to the parallel mode of circulating direction of normal that carries the big face of the area hold body and the cold air of holding body towards this year, can prolong cold air thus and carry the holdup time of holding the surface at this position.Thereby, can prolong and carry the photochemical catalyst hold on the body and the time of contact of cold air, consequently, can improve the bacteria-eliminating efficacy of cold air.
In addition, held body in above-mentioned year and intersect according to the normal of the big face of the area circulating direction with above-mentioned cold air, the mode that above-mentioned cold air flows along the two sides is configured.
Thus, cold air is pasting to carry and is holding the two sides of body and pass through.Therefore, can when suppressing the wind path impedance, guarantee to carry the amount of contact of holding body and cold air morely, can improve deodorizing and bacteria-eliminating efficacy.
In addition, in above-mentioned circulating cold air path, can above-mentioned cold air be circulated between above-mentioned storeroom and above-mentioned cooling body by fan, above-mentioned irradiation means cold air holding in above-mentioned year body around flow during held body to above-mentioned year and shine above-mentioned exciting light.
According to this structure, can cold air carrying hold body around flow during hold body irradiation exciting light to carrying.Thus, can carry out the degerming and the deodorizing of cold air expeditiously.In addition, can irradiation means always be lighted, and realize the long lifetime of energy-conservationization and irradiation means.

Figure 22 (a), Figure 22 (b) and Figure 22 (c) are the figure that in the expression embodiment 8 bactericidal device 200 is arranged on the example that the position is set under the situation in the pipeline.
For example, shown in Figure 22 (a), also can bactericidal device 200 be set in discharge line 129a near the position of cold air left and right sides branch at refrigerating chamber.By bactericidal device 200 is arranged on this place, by the cold air of degerming and deodorizing from about outlet 130 in refrigerating chamber 102, discharge equably.
In addition, for example, shown in Figure 22 (b), also can bactericidal device 200 be set near with the outlet in the discharge line 129a 130 at refrigerating chamber.By bactericidal device 200 is arranged on this place, thereby carry out the degerming and the deodorizing of cold air before can in refrigerating chamber 102, blowing out at the cold air of circulation in freezer 100.That is, the cold air of cleaning can be blown out in refrigerating chamber 102.
In addition, in Figure 22 (a) and Figure 22 (b) bactericidal device 200 be provided with direction be carry hold body 201 in the front and irradiation means 202 in direction inboard or in contrast, but also can not be such direction that is provided with.
For example, shown in Figure 22 (c), also can hold body 201 in the left side and the mode of irradiation means 202 on the right side is provided with bactericidal device 200 to carry.Perhaps also can carry in the left side and hold the mode of body 201 bactericidal device 200 is set on the right side with irradiation means 202.
That is, as long as bactericidal device 200 is provided with the position according to suitably decisions such as the size and dimensions of pipeline in pipeline.For example, bactericidal device 200 also can not be arranged on refrigerating chamber with in the 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, dispose bactericidal device 200.In addition, also can about two sides configuration bactericidal device 200.
More than, use Figure 22 (a)～Figure 22 (c) that the example that bactericidal device 200 is configured in the allocation position under the situation in the pipeline has been described.
At this, bactericidal device 200 so work as under the situation about being arranged in the refrigerating chamber 102, also plays the function as the illumination in the refrigerating chamber 102 owing to have the irradiation means 202 of holding body 201 irradiation exciting lights to carrying as mentioned above.
In addition, under situation about bactericidal device 200 being arranged in the pipeline, as mentioned above, has the effect that suppresses the LED substrate and carry the generation of the dewfall of holding body 201.
Therefore, be accommodated in the pipeline by a part in a plurality of light sources 132 that only bactericidal device 200 had, other part light sources are configured on the position that can shine in the refrigerating chamber 102, thereby can make bactericidal device 200 in the generation that suppresses dewfall, carry out the degerming and the deodorizing of cold air, 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 the pipeline, the mode that other light sources 132 is present in the position of irradiation in the storeroom is provided with the situation of bactericidal device 200.
Figure 23 be in a plurality of light sources 132 of expression embodiment 8 only a part be present in the figure of the example that the position is set of the bactericidal device 200 under the situation in the pipeline.
Particularly, 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 the refrigerating chamber usefulness discharge line 129a.Have to carry in the position configuration relative and hold body 201 with this two light sources 132.
In addition, be present in refrigerating chamber and be configured on the position that to shine in the refrigerating chamber 102, be provided with transparent luffer boards 209 in the inner wall section of the refrigerating chamber 102 in the front of this light source 132 with an outer light source 132 of discharge line 129a.
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 carry and hold body 201 and be configured on the position relative with the high light source of brightness 132.
Thus, can realize the long lifetime of the low light source of brightness 132, and can make based on carrying the bacteria-eliminating efficacy of holding body 201 effectively actual.
In addition,, also help to carry the rising of holding body 201 atmosphere temperature on every side, can bring into play the effect of the generation that suppresses dewfall even the low light source 132 of brightness can not fully carry out under the situation about exciting of catalyst.
Figure 24 is the figure of the structural outline of the bactericidal device 200 under the situation of central authorities of embodiment 8, the light source 132 that brightness is the high row that are configured in light source 132.In addition, bactericidal device 200 shown in Figure 24 is configured in top (with reference to Fig. 8) in the freezer 102 in the mode identical with the freezer 100 of embodiment 3.
As shown in figure 24, in the row that are made of a plurality of light sources 132, the light source 132 that brightness is high is configured in central authorities.In addition, carrying of width that will be narrower than the width of these row held body 201 and 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, hold body 201, on the basis of above-mentioned effect, can also be blown into bactericidal device 200 under the situation of cold air, will carry out degerming from both sides' cold air expeditiously from left and right sides both sides by disposing a plurality of light sources 132 like this and carrying.
In addition and since about the front of the low light source 132 of brightness do not exist to carry and hold body 201, so these light sources 132 can be brought into play the function as the illumination in the refrigerating chamber 102 better.
For example, hold under the situation that is carried with titanium oxide on the body 201 as catalyst carrying, the ultraviolet light source 132 that produces black light to be configured near the central authorities of row of light source 132.In addition, beyond the light source 132 that produces visible light being configured near the central authorities.
When using Figure 24 that above-mentioned configuration is described, produce ultraviolet light source 132 in the central configuration of these row, configuration produces the light source 132 of visible light about it.
In addition, hold body 201 position configuration the carrying of width shorter relative than the width of these row of light source 132 with producing ultraviolet light source 132.
Thus, the light source 132 of central authorities can excite to be carried holds the titanium oxide that body was held in 201 years, simultaneously, about light source 132 can play function as the illumination in the refrigerating chamber 102.
Figure 25 is the figure of the structural outline of the bactericidal device 200 under the situation of central authorities of expression light source 132 embodiment 8, that brightness is the low row that are configured in light source 132.In addition, bactericidal device 200 shown in Figure 25 is configured in the pipeline.
As shown in figure 25, in the row that are made 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 carry hold body 201 be configured in remove near this row central relative position, position on.That is, carry and hold body 201 and be configured in the position relative with the high light source of brightness 132.
Hold body 201 by disposing a plurality of light sources 132 like this and carrying, as shown in the figure, can be used in and hold the central authorities that allocation position that body 201 is installed in the screw 216 in the freezer 100 is arranged at bactericidal device 200 carrying.
That is, hold body 201, thereby on the basis of above-mentioned effect, can also balance will carry well and with few parts and hold body 201 and for example be arranged in the pipeline by disposing a plurality of light sources 132 like this and carrying.
In addition, exist two to carry and hold body 201 in Figure 25, to hold body 201 also can be any one but carry.In this case, only hold the relative light source 132 of body 201 and have high brightness and get final product with carrying.In addition, shown in also can formation figure will have two carry hold body 201 in conjunction with after the degree size carry near the central authorities of holding body 201 structure that is installed in inner-walls of duct etc. by screw 216.
In Figure 24 of above explanation etc., the direction of illumination of the exciting light of light source 132 was held body 201 approximate vertical with respect to flat year.But light source 132 also can be from holding the direction irradiation exciting light of body 201 from tilting with respect to carrying.
Figure 26 (is represented by chain-dotted line for the direction of illumination of the exciting light of embodiment 8.Identical in Figure 27 and Figure 28) hold the light source 132 under the vertical situation of body 201 and carry the allocation plan of holding body 201 with respect to carrying.
Particularly, in Figure 26, bactericidal device 200 is arranged in the pipeline that width is W.In addition, in order to make explanation clear, show a light source 132 among the figure and carry the position relation of holding body 201.
At this, the feature of light source 132 for example has as mentioned above that its projecting direction has directive property, and illumination angle is narrower and small.Therefore, as shown in figure 26, when light source 132 is held under the body 201 relative situations about being configured in the narrow and small pipeline of width with carrying, can not hold body 201 and be controlled at irradiation area all carrying.
Particularly, light source 132 only can be to the face of holding the maximum area of body 201 in flat year (below be also referred to as " interarea "), be the area illumination exciting light that carries the upper surface of holding body 201 among Figure 26 less than the regulation zone.
In addition, when the direction of illumination of keeping exciting light like this with respect to carrying when widening irradiation area under the situation hold the vertical state of body 201, can consider to increase light source 132 and carry the distance of holding body 201.But in pipeline, can not guarantee so long distance.
In addition, no matter whether in pipeline,, exciting light is reduced to the stimulation effect of catalyst owing to increase light source 132 and carry the distance of holding between the body 201.
Therefore, as shown in figure 27, according to from disposing light source 132 with respect to carrying the mode hold the direction irradiation exciting light that body 201 tilts.
Figure 27 is that direction of illumination embodiment 8, that make exciting light is with respect to carrying the light source 132 under the situation of holding body 201 inclinations and carrying the allocation plan of holding body 201.
Particularly, make the light source 132 as irradiation means, the direction of illumination that is arranged at exciting light is towards with respect to carrying the direction that the interarea of holding body 201 can not become vertical, and on this light source 132 position relative in addition with the central authorities of interarea.
Thus, no matter whether coexist mutually to be provided with light source 132 and to carry in the pipeline of width W and hold body 201, the Zone Full of interarea can both be controlled in the irradiation area with Figure 26.
In addition, the distance of carrying the right-hand member hold body 201 and light source 132 of Figure 27 is than this distance under the situation shown in Figure 26.But, light source 132 and carry the beeline of holding body 201 and situation shown in Figure 26 roughly the same, can not make to excite the effect of catalyst significantly to reduce.
In addition, improve, so improve as carrying degerming and the deodorizing effect of holding body 201 integral body owing to carry the ratio of light area in the surface area of holding body 201.
In addition, in Figure 27, the mode that is controlled at according to the Zone Full of interarea in the irradiation area of light source 132 disposes light source 132.But, light source 132 also can be set make the requirement ratio of interarea above, for example be controlled in the irradiation area more than 80%.
In addition, for example also can determine light source 132 with respect to carrying the position that is oppositely arranged of holding body 201 with the benchmark more than 40% that carries the surface area of holding body 201.
That is,, compare, hold zone wider in the surface area of body 201 and be controlled in the irradiation area and get final product carrying with the situation of as shown in figure 26 interarea vertically being shone exciting light as long as be configured to as shown in figure 27 under the situation that light source 132 is set obliquely.
In addition, in Figure 27, be illustrated, make and be controlled in the irradiation area of these light sources more than the requirement ratio of interarea but a plurality of light sources 132 also can be set about a light source 132.
For example, also can carry and hold body 201, shine exciting light respectively obliquely from two light sources 132, thereby the Zone Full of interarea is controlled in the irradiation area with respect to one.
In addition, in the present embodiment, carry and to hold body 201 and be tabular, be the rectangular shape of thin thickness.Therefore, paying close attention to as the big face of area is interarea, by interarea being shone more exciting light, realizes the raising of degerming and odor removal efficient.
But, also to consider to carry the face beyond the interarea hold body 201 sometimes, promptly carry the area of the side situation about in the exciting of photochemical catalyst, can not ignore just of face all around of holding body 201 among Figure 27.That is, also to be considered as the thicker situation of thickness of holding body 201 in flat year.
In this case, also can dispose more than one light source 132 makes interarea and each side be controlled in the irradiation area.In addition, in Figure 27, also shine under the situation of exciting light, also can dispose the light source 132 that is used for this interarea irradiation exciting light serving as the interarea that carries the lower surface of holding body 201.
In addition, in Figure 27, illustrate bactericidal device 200 is arranged on situation in the pipeline.But as long as light source 132 and to carry the relative position relation of holding body 201 be position relation shown in Figure 27, then no matter bactericidal device 200 the position is set for where, can both in narrow space, bring into play the effect of the degerming and the deodorizing of cold air expeditiously.
At this, for example, as shown in figure 27, light source 132 is positioned at the top, carries to hold body 201 and be positioned under the situation of below and have peculiar effect as described below.
That is: hold under the situation of body 201 dewfall when carrying, its water droplet can not flow into the LED substrate, can keep the reliability of bactericidal device 200.
In addition, as shown in figure 28, when light source 132 is in the below, carries and to hold body 201 and be under the situation of top and have distinctive effect as described below.
To be the direction of illumination that makes exciting light hold body 201 and tilt with respect to carrying Figure 28, and be in light source 132 down, carry hold body 201 under the situation of last upper and lower relation light source 132 and carry the allocation plan of holding body 201.
Like this, as the light source 132 of irradiation means with carry and hold body 201, be used to the free convection that the heating from light source 132 causes, can suppress to carry the generation of the dewfall of holding body 201 effectively by configuration.
(making the concrete example of the method for degerming and deodorizing effect raising)
Carry and to hold body 201, the resin that adopts the light of easy exciting light catalyst to see through as the resin of base material as mentioned above for rubbing the structure of the filtration shape that forms into the fiber entanglement that photochemical catalyst is arranged.
That is: certain ratio of carrying the exciting light of holding body 201 irradiations is held body 201 through carrying.Therefore, bactericidal device 200 also can possess the exciting light reflection hold body 201 is carried in projection, makes it hold the reflecting plate of body 201 incidents to carrying.
Thus, can improve the degerming and the deodorizing effect of 200 pairs of cold air of bactericidal device.
Figure 29 (a) and Figure 29 (b) be expression embodiment 8 reflecting plate 215 example is set and by the figure of the situation of reflecting plate 215 reflection exciting lights.
Shown in Figure 29 (a), clip to carry and hold body 201 and reflecting plate 215 is set at the opposition side of irradiation means 202.
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, shown in Figure 29 (b), see through from light source 132 irradiation and to carry plate 215 reflections that are reflected of the exciting light of holding body 201, incide once more to carry and hold body 201.
Therefore, compare, can excite expeditiously to be carried and hold the catalyst that body was held in 201 years, improve degerming and odor removal efficient with the situation that does not have reflecting plate 215.
In addition, in Figure 29 (a) and Figure 29 (b), carry and to hold the setting that adjoins each other of body 201 and reflecting plate 215.But, also can hold body 201 and separate setting carrying with reflecting plate 215.
That is, carry and to hold the interval of body 201 and reflecting plate 215, incide once more and carry the distance of holding body 201 and get final product so long as can make to see through and carry plate 215 reflections that are reflected of the exciting light of holding body 201.
As mentioned above, freezer of the present invention is possessing a plurality of light sources 132 to carrying in the irradiation means 202 of holding body 201 irradiation exciting lights.Particularly, adopt LED as light source 132.
Like this, utilize 132 pairs of a plurality of light sources to carry to hold body 201 irradiation exciting lights, for example the part of the exciting light that sends from a plurality of light sources 132 can be used for the illumination in the storeroom thus.
In addition, send exciting light, can improve the atmosphere temperature of bactericidal device 200, suppress to carry the generation of the dewfall of holding body 201 grades by a plurality of light sources 132.
Thus, can prevent mainly fault and the degerming of bactericidal device 200 and the reduction of deodorizing effect of the bactericidal device 200 that causes by dewfall.
In addition, irradiation means 202 by a plurality of light sources 132 on the same one side that is configured in a substrate, is held body 201 irradiation exciting lights to carrying.
Thus, for example can reduce the number of components of bactericidal device 200.
In addition, bactericidal device 200 also can be installed in storage the piping outside the house of a part that constitutes the circulating cold air path, in this case, in the pipeline with to compare be the place that is not vulnerable to the influence of extraneous gas in the storeroom.Therefore, by like this above-mentioned bactericidal device being installed in the pipeline, can being suppressed at the substrate that disposes LED and producing dewfall on the body with carrying to hold.
In addition, the LED substrate also can be configured in the freezer 100 as follows, that is: the only a part of light source 132 in a plurality of light sources 132 is present in storage the piping outside the house of a part that constitutes the circulating cold air path, and other light sources 132 is present on the position that can shine in the storeroom.
Thus, bactericidal device 200 can be realized simultaneously as the function of the device that carries out the degerming of the cold air in the storehouse and deodorizing with as the function of the illumination in the storehouse.
In addition, also can make a plurality of light sources 132 line up row, the brightness difference of a plurality of light sources 132, with carry hold body 201 be configured in a plurality of light sources 132 in regulation brightness more than the relative position of light source 132 on.
By formation like this, can guarantee certain degerming and deodorizing capability, and can realize the long lifetime of the light source 132 that energy-conservationization and brightness are lower.
In addition, in such structure, the above light source 132 of regulation brightness is configured near the central authorities of row, carries the narrow width of the width ratio row of holding body 201.
Thus, bactericidal device 200 constitutes symmetrical structure, by make cold air from about be blown into bactericidal device 200, can carry out good degerming of efficient and deodorizing.
In addition, also the light source 132 below the regulation brightness in a plurality of light sources 132 can be configured near the central authorities of row, carry the narrow width of the width ratio row of holding body 201.
Thus, become with about the higher light source 132 of brightness relatively dispose to carry and holds body 201, can be in the position relative, be to dispose near the central authorities of bactericidal device 200 to be used for bactericidal device 200 is installed in screw in the freezer 100 etc. with light source 132 below the regulation brightness.
In addition, also can be that a plurality of light sources 132 constitute row, the part of a plurality of light sources 132 is sent black light, other send visible light, the light source 132 that sends black light is configured near the central authorities of row, catalyst is excited by black light, carries the width hold body 201 narrow width than row, is configured in the position relative with the light source 132 that sends black light.
Thus, near the LED the central authorities can excite to be carried and hold the catalyst that body was held in 201 years, and simultaneously, other LED can play the function as the interior illumination of for example storeroom.
(embodiment 9)
Then, use Figure 30 that embodiments of the present invention 9 are described.
In addition, the basic structure of the freezer 100 of embodiment 9 is identical with the freezer 100 of embodiment 3, omits its explanation.
That is to say, the freezer 100 of embodiment 9 also with the freezer 100 of embodiment 3 similarly, in freezer 102, possess bactericidal device 200.
In bactericidal device 200, as mentioned above, held body 201 irradiation exciting lights in 202 pairs years by irradiation means, then carry the photochemical catalyst of holding body 201 and be excited.When photochemical catalyst is excited, produce the OH free radical from airborne moisture, carry out being carried the oxidation Decomposition of the foul smell composition of holding body 201 seizure and the bacteriolyze of bacterium.
Therefore, as embodiment 9, the ON and the OFF of the power supply of the irradiation that is used for exciting light, promptly relevant with the control of the ON of light source 132 and OFF technology item are described.
Figure 30 (a), Figure 30 (b) and Figure 30 (c) are the figure of the embodiment that lights control of expression light source 132.In addition, " LED " expression light source 132 in Figure 30 (a)～Figure 30 (c).

In addition, during not rotating, make light source 132 be OFF, can realize the province's electrification of bactericidal device 200 and the long lifetime of light source 132 at cooling fan 121.
In addition, under the situation that cooling fan 121 does not rotate, shown in Figure 30 (b), insulated door 107 open during also can hold body 201 irradiation exciting lights to carrying.
In freezer 100, under the situation that insulated door 107 is opened, for the extraneous gas of doing one's utmost to suppress moistening and high temperature flows in refrigerating chamber 102, cooling fan 121 is stopped.
But,, can not prevent the inflow of extraneous gas fully even cooling fan 121 is stopped.Therefore, be set under the situation in the refrigerating chamber 102, carry and hold body 201 and the LED substrate can dewfall as bactericidal device that present embodiment is shown in 200.
Therefore,, also make light source 132 be ON, it is lighted even under the situation that cooling fan 121 does not rotate.Thus, can suppress the generation of dewfall.
Particularly, only under insulated door 107 pent states and the power supply that drives usefulness when the rotation of cooling fan 121 be under the situation of OFF, the power supply of the irradiation that is used for exciting light of control irradiation means 202 is OFF, under other situations for being ON, thereby realize the control of lighting of the light source 132 shown in Figure 30 (b).
By such control, during cooling fan 121 rotation and insulated door 107 be opened during, hold body 201 irradiation exciting lights to carrying.
In addition, shown in Figure 30 (c), also can with control cold air to the windscreen of the inflow of refrigerating chamber 102, be that refrigerating chamber is synchronous with the switching of air door 125, the ON and the OFF of control light source 132.
Particularly, when the refrigerating chamber that cold air is intermittently carried out to the inflow of refrigerating chamber 102 with air door 125 when opening state, make light source 132 be ON.In addition, when refrigerating chamber with air door 125 when closing state, make light source 132 be OFF.
In addition, also can be based on the switching of the ON of cooling fan 121 and OFF and refrigerating chamber, the ON and the OFF of control light source 132 with air door 125.
Particularly, the power supply that also can be only drives usefulness in the rotation of cooling fan 121 is ON, and refrigerating chamber with air door 125 for open state during, make light source 132 be ON, making light source 132 during other is OFF.
Control lighting of light source 132 like this, also can cold air carrying hold flow around the body 201 during hold body 201 irradiation exciting lights to carrying, and can realize the long lifetime of light source 132.
More than the control of lighting of Shuo Ming various light sources 132 is undertaken by control substrate 122.
As mentioned above, freezer of the present invention, by carrying at cold air hold body 201 around flow during hold body 201 irradiation exciting lights to carrying, thereby can carry out the degerming and the deodorizing of cold air expeditiously.In addition, irradiation means 202 is always lighted, be realized the long lifetime of energy-conservationization and irradiation means 202.
In addition, it is synchronous that the ON of the power supply of the irradiation that is used for exciting light that also can be by making irradiation means 202 and the rotation of OFF and fan drive the ON and the OFF of power supply of usefulness, and cold air carrying hold body 201 around flow during hold body 201 irradiation exciting lights to carrying.
Thus, for example, under the situation in bactericidal device 200 is installed in the pipeline of a part that constitutes the circulating cold air path, only the cold air by the fan forced conveyance carrying hold body 201 around flow during, hold body 201 irradiation exciting lights to carrying.
That is, only during the degerming that can carry out cold air most effectively and deodorizing, hold body 201 irradiation exciting lights to carrying, can efficient higher and more effectively carry out the degerming and the deodorizing of cold air.
In addition, irradiation means 202, even under the situation that cooling fan 121 does not rotate, also can door be opened during hold body 201 irradiation exciting lights to carrying.
Like this, by gas externally flow into easily in the freezer 100 during promptly door be opened during hold body 201 irradiation exciting lights to carrying, can be suppressed to carry and hold body 201 and irradiation means 202 produces dewfall.
By suppressing the generation of dewfall, can realize the reliability of bactericidal device 200 and the raising of degerming and odor removal efficient.
In addition, irradiation means 202, the power supply that only is used in the irradiation of exciting light under power supply that the rotation of door closing state and cooling fan 121 drives usefulness is the situation of OFF is OFF, be ON in other cases, thus during cooling fan 121 rotation and door open during, also can hold body 201 irradiation exciting lights to carrying.
Like this, ON and OFF according to the power supply of the combination control irradiation means 202 of the switching of the ON of cooling fan 121 and OFF and door can suppress the generation of the dewfall of bactericidal device 200 thus, and can carry out the degerming and the deodorizing of cold air effectively.
In addition, freezer of the present invention also has windscreen, this windscreen can be blocked cold air outside being present in storeroom and constitute the inflow of pipeline in storeroom of the part in circulating cold air path with opening and closing, bactericidal device 200 is installed in the storeroom, irradiation means 202, the power supply that is used in the irradiation of exciting light when windscreen is out state is ON, is OFF when windscreen makes power supply when closing state, thus also can cold air carrying hold body 201 around flow during hold body 201 irradiation exciting lights to carrying.
Like this, synchronously make the power supply of irradiation means 202 become ON and OFF, only be in out state when windscreen by switching with windscreen, the cold air that flows into storeroom carry hold body 201 around flow during, hold body 201 irradiation exciting lights to carrying.
That is, can be only during the degerming that can carry out cold air most effectively and deodorizing, hold body 201 irradiation exciting lights to carrying, can efficient highland and more effectively carry out the degerming and the deodorizing of cold air more.
In addition, the device that irradiation means 202 so long as can launch comprises the light of wavelength that can the exciting light catalyst gets final product, and as mentioned above, can utilize LED to hold body 201 irradiation exciting lights to carrying.
Thus, can suppress the generation of the unwanted heat that bactericidal device 200 causes.In addition, also can reduce the consumption of the electric power that bactericidal device 200 causes.
