Description

  The present invention is a device that circulates air such as an air conditioner or an air purifier, and automatically collects dust adhering to a filter for collecting dust in the air to be circulated periodically and collects the collected dust. The present invention relates to a container to be stored, and relates to a device for removing germs contained in dust accumulated in the container.

  Japanese Patent Application Laid-Open No. 2005-283121, for example, automatically collects dust from a prefilter of an air conditioner and applies a function to prevent the propagation of germs to the collected container. Further, as an example of utilizing allyl isocyanate composed of an organic volatile component wasabi extract component as a function of suppressing the propagation of the adhering germs in the air conditioner during air conditioning operation, for example, JP-A-2004-251473 There is a number.

JP 2005-283121 A JP 2004-251473 A

  However, in the technology described in JP-A-2005-283121, an antibacterial agent is added to the resin that constitutes a container for storing dust, and the added antibacterial agent exhibits an antibacterial action by contact with various bacteria. For this reason, it is not possible to expect the effect of suppressing the propagation of various germs that inhabit the dust accumulated by the accumulation of dust. Further, when an antibacterial agent is added to the resin, there is a possibility of discoloration. In addition, although there is a light beam having a short wavelength such as ultraviolet rays or sterilization lines as a non-contact type antibacterial means, the light beam is blocked by fibrous dust or the like, and the sterilization effect cannot penetrate into the dust. Ultraviolet rays also cause the resin itself to deteriorate. In addition, the technique described in Japanese Patent Application Laid-Open No. 2004-251473 is intended to suppress the propagation of germs throughout the air conditioner. However, when the air conditioner is operating, the amount of air flow is large relative to the volatilization amount of allyl isocyanate. It is difficult to reach the allyl isocyanate concentration necessary for the treatment, and the contact time between the allyl isocyanate and the various bacteria is short, and the effect of suppressing the propagation of the various bacteria cannot be expected. In addition, when the air conditioner is shut down, the air conditioner is filled with volatile components of allyl isocyanate and expected to suppress the growth of germs attached to the air conditioner. The improvement cannot be expected. In addition, even when the amount released is adjusted so that the concentration of bacteria can be suppressed, it does not have a sealed structure as described above. There is a problem that the irritating odor of wasabi is generated from the air conditioner. In addition, when the amount of release is increased, highly volatile allyl isocyanate cannot maintain a period in which miscellaneous bacteria can be suppressed for a long time.

  An object of the present invention is to suppress the propagation of germs attached to an air conditioner. However, since the germs are very small, the residence time in the air conditioner is short, and usually adheres to dust in the air, and the dust adheres due to the charged state of the resin inside the air conditioner. Moisture in the air condenses, the inside of the air conditioner becomes highly humid, dust becomes damp, and germs grow. Therefore, it is considered that the propagation of bacteria in the entire air conditioner can be suppressed by removing bacteria in the filter that efficiently collects dust. However, in the conventional method of adding an antibacterial agent to the filter, it is possible to suppress the growth of germs that are in direct contact with the filter, but if the germs stay on the filter without contacting the filter via dust such as fibers, The bacteria on the filter cannot suppress the growth, and there is a possibility of further contaminating the inside by operating the air conditioner. In addition, since the area is large even if non-contact type germ removal agent is used for the entire dust on the filter, it is difficult to allow the germ removal agent to uniformly act over the entire space, and it adheres to the inside of the air conditioner. It is more difficult to control the propagation of all germs because the air conditioner is not sealed.

  The object of the present invention is to provide an air conditioner that solves such problems with a simple structure at low cost, always cleans the inside of the air conditioner, and can perform indoor air conditioning with clean air.

  The first feature for achieving the above object is to have a function of collecting dust adhering to the filter. The container for storing the collected dust has a sealed structure, and the container is volatile to an inorganic germ disinfectant. What is formed with a resin added with an organic / inorganic hybrid germ-free remover containing an organic germ-free remover, or in which a germ-free cassette containing the organic / inorganic hybrid germ-free agent is placed in a container .

  Sanitary hygiene by a germ removal device for simple and inexpensive removal of dust contained in the dust collected in the container that automatically collects dust attached to the filter for collecting dust in the air to circulate. It can store dust for a long time, can be easily discarded without feeling uncomfortable when it is thrown away, and it can always keep the air conditioner clean without frequent troublesome filter cleaning, The air blown from the air conditioner can always be kept clean.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a side sectional view of an air conditioner. 1 is a front grille, 2 is a blower blade, 3 is a frame on the back of the main body, 4 is a dew tray, 5 is a heat exchanger, 6 is a ventilation fan, and 7 is a pre-heater. A movable brush for collecting filter dust, 8 is a pre-filter, and 9 is a suction grille.

  FIG. 2 shows a front view of the air conditioner with the decorative grill removed, and 10 shows a dust collecting portion. 11 is an organic / inorganic composite germ removal cassette.

  FIG. 3 is an enlarged view of the dust collecting unit 10, and 13 is a dust collecting container for storing collected dust, in which an organic / inorganic composite germ removing material is kneaded.

  In FIG. 1, by operating the ventilation fan 6, air flows as indicated by white arrows, and dust in the passing air is collected by the prefilter 8. The dust collected by the pre-filter 8 is collected by the movable brush 7, collected by the dust collecting unit 10 installed on the side of the air conditioner main body shown in FIG. 2, and accumulated in the dust collecting container 13. After the accumulated dust has passed for a certain period, the dust collecting container 13 is pulled out from the air conditioner body, and the accumulated dust is thrown into a trash can or the like. Here, the accumulated dust contains many germs and molds that cannot be seen with the naked eye. If some antibacterial and mildew prevention measures are not taken, germs will grow and mold will be thrown away. This will give the user discomfort. FIG. 4 is a diagram illustrating the internal structure of the dust collecting portion. The dust collecting container 13 is kneaded with an organic-inorganic composite germ-removing material, and can kill or suppress dust germs and mold that come into contact therewith. Further, since the organic germ removing agent having volatility is gradually released from the dust collecting container 13, the germ removing material penetrates into dust that does not contact the dust collecting container 13, so that germs and molds can be killed. Furthermore, the organic germ removal agent is gradually released also from the organic / inorganic composite germ removal cassette of 11 and the dust collection container 13 is filled with the active ingredient of the germ suppression and fungus prevention, thereby killing germs and fungi contained in the dust. The inside of the dust collection container can be kept hygienic. This makes it possible to sanitize the waste in the container. Here, the organic / inorganic composite germ removal cassette 11 may have a honeycomb shape so that it can be easily released.

  In the enlarged view of the dust collecting part of FIG. 3, 12 is a dust collecting mechanism. The dust collecting mechanism 12 has a raised shape such as an etiquette brush. The dust collected by the movable brush 7 passes over the dust collection mechanism 12 installed in the dust collection unit 10, so that the dust is caught by the raising and remains in the dust collection mechanism 12, and the tip of the movable brush Will be clean. The dust collecting mechanism 12 is arranged so that the two rollers rub against each other, and the dust caught by the dust collecting mechanism 12 is collected by rotating the two dust collecting parts so as to rub against each other. , While rubbing several times, it leaves the raised surface and falls to the dust collecting part 10. Although bacteria are lurking in the falling dust, the bacteria are sterilized by the active components of the organic and inorganic composite bacteria removal cassette 11 and the dust collection container 13 which are disposed in the dust collection unit 10 and volatilized from the dust collection container 13 and hygienic. In addition, it is possible to keep dust and mold prevention effect for a long period of time due to the sustained release of active ingredients, which is a feature of organic / inorganic composite germ removal agent. There is no longer to do.

  Since the organic-inorganic composite germ-removing agent is volatile due to the inclusion of the organic disinfecting agent, the anti-bacterial and anti-fungal active ingredient can be infiltrated into the inside of the fiber by filling the dust accumulation portion.

  Here, the organic / inorganic composite germ removing agent includes those containing isothiazoline / layered silicate as a component and those containing ammonium salt / layered phosphate as a component.

  FIG. 5 shows the relationship between the addition amount of organic / inorganic composite germ removal agent and the decrease in tensile elongation properties of a test piece prepared by kneading an organic / inorganic composite germ removal agent containing isothiazoline / layered silicate into ABS resin. FIG. From this figure, assuming that the tensile elongation rate of the initial test piece to which no bacteria-removing material is added is 100, the elongation rate is reduced by 50% when 10% is added. If added more than this, the mechanical strength of the resin cannot be maintained. In addition, based on the mold prevention test method (Hello method) established by the Japan Household Appliances Fair Trade Council, the fungus was sprayed on the petri dish and the organic / inorganic composite germ removal agent was incorporated into it. As a result of confirming the antifungal effect after culturing for 7 days at a temperature of 25 ± 1 ° C, the organic bacteria removal component is volatilized, and there is a mold-inhibiting zone (halo) that does not generate mold around the test piece. Appears at 0.5% addition. Therefore, the amount of the organic / inorganic composite germ removal agent added to the resin is 0.5% to 10%, so that the germs and mold contained in the dust can be killed and the inside of the dust collecting container can be kept hygienic.
