Abstract
A fridge-freezer equipped with a deodorizing unit which has a filter including photocatalyst and a light emitting unit including an LED as a light source mounted on a substrate. The fridge-freezer is designed to solve problems posed by conventional fridge-freezers. One of the problems is that in the case of using a glass-tube type lamp such as a black light or a cold cathode tube as the light source, the light source becomes large in size which requires a large space for installation. This does not allow the deodorizing unit to be installed in the compartments in the refrigerator. Another problem is that the deodorizing unit was not designed to be safe for food in case that part of the deodorizing unit is damaged to give harmful damage to food.
Description
Technical field
The present invention relates to the freezing and refrigeration technology, particularly in refrigerator, be provided with and implement the refrigerating and cold storage refrigerator that the odor removal of usefulness is handled in deodorizing.
Background technology
The schematic side elevation that Figure 28 is used by critical piece in the disclosed a kind of refrigerating and cold storage refrigerator of TOHKEMY 2000-249460 communique for expression.The schematic cross sectional view that Figure 29 uses for its optics catalytic module of expression, the schematic cross sectional view that Figure 30 uses for ice-making compartment in this refrigerating and cold storage refrigerator of expression.In the accompanying drawings, what reference number 1 was represented is the refrigerating and cold storage refrigerator main body, reference number 2 expression be arranged on ice-making compartment this body interior place, that be box shape, and have ice making with ice cube manufacturing department 3, and has the ice cube preservation portion 4 that the ice that ice cube manufacturing department 3 is produced implements to store usefulness in the bottom at the ice-making compartment internal upper part.At ice cube manufacturing department 3 places the ice cube with the recess that can make water maintenance reservation shape is set also and makes vessel 5, ice cube preservation portion 4 also be provided with can receive make by ice cube that the ice cube produced at vessel 5 places is used, on the ice cube preservation portion 6 of side opening, and also be provided with optics catalytic module 7 at the upper side position place that ice cube is made vessel 5.
Optics catalytic module 7 can be as shown in figure 29, in the surface of light exposure tube 7a by such as gelling (ゾ Le ゲ) method and particulate suspension or the like, lid be covered be transparent or semitransparent, such as titanium (TiO
2) or the like photochemical catalyst 7b.In order to effectively utilize ultraviolet ray, preferably adopt such as black light lamp or the like as the light exposure tube 7a in the optics catalytic module 7 as illumination beam.
Another kind of form can be as shown in figure 30, is provided with minute surface or metal as light-reflecting components 8 at the medial surface place of ice cube manufacturing department 3.Can also implement metal coating handles, so that can be by the mode of light-reflecting components 8 is set, reverberation in the light beam that will be launched by optics catalytic module 7 is focused to optics catalytic module 7 places, to increase the exposure to photochemical catalyst, further promotes the decomposition reaction of its enforcement.
Figure 31 shows by the part among the disclosed embodiment of Japanese kokai publication hei 9-61042 communique, the form of the composition of promptly representing defrosting glass tubular type thermal source, wherein reference number 28 expressions is glass tube, and what reference number 29 was represented is filament wire, and what reference number 30 was represented is deodorizing coating.This thermal source is used for that cooler is implemented defrosting and handles as shown in the figure, so be installed in the place, bottom of cooler.
Formerly the refrigerating and cold storage refrigerator in the technology as mentioned above, be what to adopt such as the glass tubular type bulb of black light lamp and cold-cathode tube or the like as light source, can be subjected to being provided with the restriction in space because light source is bigger, can not be so have again in other indoor problem that odor removal is set of refrigerating and cold storage refrigerator.
And, owing to light source is made of glass tube, so, also need after installing and being provided with, implement make its processing that can not be subjected to the stress effect to handle in order to prevent that it from breaking.Particularly for the occasion that adopts fluorescent lamp as light source, because portion is using mercury within it, mercury can appear at around the food when imagination is broken, so can produce unaccommodated problem when using refrigerating and cold storage refrigerator.
And what input voltage adopted mostly is the alternating voltage of 100 volts (V), so when anomaly appears in the refrigerating and cold storage refrigerator that adopts HC or the like substituted type cold-producing medium, will produce huge problem.
And, owing to be coated with deodorant at defrosting glass tubular type thermal source place, so this thermal source can not be set in the wind path.
And, for as technology formerly, it is installed in the form of the composition that ice cube is made place, vessel top, if breaking appears in the glass tubular type bulb, glass fragment may be sneaked into to ice cube, so also have the big problem that may have influence on health.
And when the way that photocatalyst coating is being formed on the member that the ice making locular wall uses, also having described coating operation needs time and drying time etc., thus the problem that activity time is prolonged.
Summary of the invention
The present invention is exactly the invention that addresses the above problem usefulness, purpose of the present invention just provides a kind of refrigerating and cold storage refrigerator that can address the above problem, and the present invention can also make deodorizing assembly lightness, the miniaturization of adopting photochemical catalyst, can eliminate simultaneously with the deodorizing assembly use when being arranged in the refrigerating and cold storage refrigerator at food location about place the problem that may occur, but also provide such as the cheap member of optics catalytic module or the like.
Refrigerating and cold storage refrigerator of the present invention can be provided with odor removal, and described odor removal can be by the filter that photochemical catalyst or photochemical catalyst and sorbing material are mixed, and disposes the light emitting devices that ultraviolet light emitting diode (LED) can take place and constitute.
And refrigerating and cold storage refrigerator of the present invention can also have filter and light emitting devices, and carries the odor removal that is integral formation by preset distance.
And refrigerating and cold storage refrigerator of the present invention can also constitute one with odor removal and air door assembly, and carries at refrigerating chamber.
And, refrigerating and cold storage refrigerator of the present invention, light emitting devices is crossed ultraviolet transparent shell by transmissive and is covered with.
And, refrigerating and cold storage refrigerator of the present invention, transparent shell has water-drip-proof structure.
And refrigerating and cold storage refrigerator of the present invention, transparent shell are crossed ultraviolet materials at transmissive and are had lens section.
And, refrigerating and cold storage refrigerator of the present invention, light emitting devices is provided with reflection part at light emitting diode (LED) location about place.
And refrigerating and cold storage refrigerator of the present invention is arranged on the temperature province that keeps different more than two at least with light emitting devices, and keeps within the special-purpose wind path of cold air of more than one blast regulator.
