Abstract

PROBLEM TO BE SOLVED: To eliminate fear for accumulating ozone in a living room, and to eliminate fear of corroding a heat exchange fan coil by ozone by providing an ozone decomposing filter in an intake port of an air conditioning fan coil unit of the living room, and providing an ozone mixer in a blowoff port. SOLUTION: Air in a living room is introduced to an ozone decomposing filter 2 from an intake port 1 of a fan coil unit to decompose a trace quantity of ozone contained in the air. This air is blown in a heat exchange fan coil 4 by an air blower 3, and is blown off in the living room after mixing the ozone by an ozone mixer 5 arranged in a blowoff port. A cassette by filling honeycomb-shaped activated charcoal or granular activated charcoal in a shallow bottom tray having the bottom of a wire net is used as the ozone decomposing filter 2, and a ceramic or Teflon cylindrical porous filter is used as the ozone mixer 5. When using this filter, the air and the ozone are excellently mixed to uniformize the ozone concentration in the air blowing off from the fan coil unit.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing and sterilizing apparatus for a living room.

[0002]

2. Description of the Related Art Conventionally, an ozone outlet is provided at an air outlet of an air-conditioning fan coil unit in a living room, and an ozone generator is turned on and off to generate intermittent ozone, and an on / off time is timer-controlled. By,
A system for controlling the ozone concentration in a living room has been implemented.

[0003]

Ozone is an unstable substance that is naturally decomposed into oxygen by itself, but its decomposition rate depends on temperature and humidity, and its half-life varies from several hours to several tens of hours. I do. When the living room is air-conditioned, the ozone concentration in the living room is exclusively affected by the ventilation volume of the living room because the influence of temperature and humidity is small. However, the ventilation volume of the room is
It varies greatly depending on the frequency of opening and closing of the entrance door other than the ventilation by the ventilation device. Therefore, if a timer is set in the daytime when people frequently enter and leave, it is practically difficult to always keep the ozone concentration in the living room constant, such as an increase in the ozone concentration at night.

A method of controlling an ozone concentration in a living room by installing an ozone sensor in a living room and changing the on / off time of an ozone generator according to the value of the sensor is conceivable. However, this method has a problem that the cost is too high. is there. Therefore,
Development of an inexpensive device that constantly controls the ozone concentration in a living room regardless of disturbance factors such as the frequency of opening and closing the entrance door has been awaited.

SUMMARY OF THE INVENTION The present invention provides an apparatus that meets this demand, and has an ozone decomposition filter at the air inlet of a fan coil unit for air conditioning in a living room, and an ozone mixer at an outlet. A deodorizing and sterilizing apparatus for a living room, characterized in that:

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. FIG. 1 is a conceptual diagram of the present invention, in which wind directions are indicated by arrows. FIG. 2 is a cross-sectional view taken along the line AA 'of FIG. The air in the living room is guided from the air inlet 1 of the fan coil unit to the ozone decomposition filter 2 to decompose a small amount of ozone contained in the air. The air containing no ozone is blown into the heat exchange fin coil 4 by the blower 3, mixed with ozone by the ozone mixer 5 installed at the outlet, and then blown into the living room.

As the ozone decomposition filter 2, a honeycomb-shaped activated carbon or a cassette in which granular activated carbon is filled in a shallow tray with a wire mesh bottom is used. As the ozone mixer 5, a ceramic or Teflon cylindrical porous filter is used. When this filter is used, the mixing of air and ozone is improved, and the concentration of ozone in the air blown out from the fan coil unit is made uniform. The ozone generator is installed in the immediate vicinity of the fan coil unit, and supplies the generated ozone to an ozone mixer via a pipe.

[0008]

According to the present invention, in any ventilation condition of the living room, the air taken into the fan coil unit is once made ozone-free, passes through the fin coil, and then mixed with ozone. Because it is blown out into the living room, there is no fear that ozone will be accumulated in the living room. Also,
There is no fear that the heat exchange fin coil is corroded by ozone.
