Description

  The present invention is a method for producing malodorous substances and odorous substances contained in the air by causing a chemical reaction by oxidation-reduction reaction between the odorous components and germs contained in the air and the germs and odors generated in the air conditioning equipment having a structure surrounded by a side plate on the outer periphery. The present invention relates to a disinfecting and deodorizing apparatus.

  Up to now, photocatalysts and ozone deodorizers have been installed in the middle part of the duct that circulates indoor air and the air (gas) inlet. However, the air (gas) that passes through many devices again generates odors from the inside of the duct due to the generation of fungi such as molds that are generated in the duct again. And other germs are brought into the room.

  Installation of photocatalysts and ozone deodorizers at the gas inlets would be expensive equipment if arranged as described above.

  For example, in Japanese Patent Application No. 10-277612, a photocatalyst / ozone deodorizer was installed at the air (gas) inlet, but maintenance (cleaning / cleaning / disinfecting) is required in the inside of the equipment and duct. Was difficult.

  However, by attaching to the indoor air (gas) discharge port, the circulation type air conditioner and the outside air intake type air conditioner can be sterilized and deodorized at the room / air (gas) discharge port.

  The filter uses the thing used by the gazette of Japanese Patent Application No. 7-248384, and obtains the effect which performs antibacterial, disinfection, deodorizing, and air cleaning.

  It is possible to provide a photocatalytic filter unit capable of reliably sterilizing bacteria contained in the air that has passed through the air conditioner, and an air conditioner using the photocatalyst filter unit.

This is a method that can be prevented at the end of air conditioning by installing it at the outlet of air conditioning equipment (air conditioner, air conditioning air conditioner, etc.) in each room.
A photocatalytic filter that can reliably sterilize malodors, existing malodors, bacteria, and bacterial odors contained in the air that has passed through the existing air conditioner and new air conditioner (with the outer periphery surrounded by a side plate), and It is an object of the present invention to provide a photocatalytic filter capable of reliably sterilizing bad odors, existing bad odors, bacteria, and bacterial odors contained in the air just before the space where fresh air is required.

  In addition, by installing a sterilization / deodorization device to prevent at the end of the air conditioning, it can be placed in a spot and can be provided at a low cost.

  In existing air conditioners and new air conditioners that are currently installed and operated, devices such as photocatalysts and ozone deodorizers are installed in the air introduction part and air blowing part, but while being sent into the space where fresh air is needed For some reason (bad odor from appliances, bad odor due to bacteria, etc.), the air odor was once again called odor, existing bad odor, bacteria, and bacterial odor in the air conditioner. A photocatalytic filter unit that can reliably sterilize malodors, existing malodors, bacteria, and bacterial odors contained in the air that has passed through existing air conditioning equipment and new air conditioners (with the outer periphery surrounded by side plates); And the air-conditioning unit using this is suppressed by a photocatalytic filter unit that can surely sterilize malodors, existing malodors, bacteria, and bacterial odors contained in the air just before the space that requires fresh air.

  A photocatalytic filter is disposed at the air inlet and the air discharge path / exhaust, and an ultraviolet lamp (black lamp) having a high sterilizing ability capable of deodorizing bad odors by the photocatalytic action is installed in front of the filter. As a result, it is sterilized and deodorized by being irradiated with ultraviolet rays, so the air that has passed through the photocatalytic filter unit is discharged as cleaning air from which dust, malodorous substances, and bacteria have been effectively removed. It will be.

  Inside the air inlet and the air outlet path / exhaust, the outer periphery is surrounded by a side plate so that it can be freely attached to and removed from the air conditioning equipment. A photocatalytic filter that removes malodorous substances. It is a filter that removes coarse dust contained in the air and is placed in the air inlet and air exhaust passage. A photocatalytic filter having an ultraviolet lamp (black lamp) that captures a substance, decomposes the malodorous substance in response to light, and irradiates ultraviolet light toward the photocatalytic filter that captures fine bacteria in the air. Install the unit.

  By linking with existing / new air conditioning systems (blowers, cooling / heating equipment, relays / solenoid valves / magnet connections to air conditioners), the room where the air is to be purified can be appropriately reduced at the spot.

  The figure which shows the outline | summary of the photocatalyst disinfection and deodorizing apparatus which is 1st Embodiment of this invention.
