JPH03233237A - Air conditioner and reclamation of its deororizing filter - Google Patents

Abstract

PURPOSE:To eliminate replacement of a deodorizing filter by reclamation and reuse of one deodorizing filter, by arranging a heater adjacent to the filter and forming an exhaust port to exhaust inside air outdoors. CONSTITUTION:When deodorizing function of a deodorizing filter 7 drops down due to full absorption of odor, normal operation of an air conditioner is stopped, a blow-off flap 6 is closed to close a blow-off port and an opening/closing door 11 of an exhaust port 9 is opened. Then power is supplied to a honey cam heater 8 to raise the temperature of the filter 7 to 100 deg.C - 150 deg.C so that the odor attached to the filter 7 can be detached therefrom and filled in a ventilation circuit 5. After this, an exhaust fan 13 is driven to driven to exhaust the odor through the exhaust port 9 outdoors, whereby the filter 7 is reclaimed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an air conditioner equipped with a deodorizing function and a method for regenerating its deodorizing filter. The air conditioner consists of an underframe 1, a heat exchanger 2, a blower 4, etc., and a deodorizing filter 7 such as activated carbon is placed in front of the heat exchanger 2. However, in such a configuration, the deodorizing filter 7
Since there is a limit to the amount of odors that can be absorbed by the filter, the deodorizing function deteriorates significantly after six months to one year of use, and the deodorizing filter must be replaced with a new one to maintain the deodorizing function.In terms of cost and usability. In order to solve the above-mentioned problems, the present invention (1) has a heating device adjacent to the deodorizing filter and an exhaust system for exhausting the air inside the air conditioner to the outside. The deodorizing filter is configured with an opening, and the deodorizing filter is heated by a heating device to remove the odor, and the odor is discharged outside from the exhaust port to regenerate the deodorizing filter and return the deodorizing function of the deodorizing filter to a state close to new. It is.

action The effect of this technical means is as follows.

In other words, when the deodorizing filter absorbs odors and its deodorizing function deteriorates, the deodorizing filter can be regenerated by desorbing and desorbing the odor without having to remove it. The same filter can be used repeatedly over a long period of time.

Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings. 1st
FIG. 1 and FIG. 2 are cross-sectional views showing an air conditioner according to an embodiment of the present invention installed on a wall. FIG. 1 shows the state during air conditioning operation, and FIG. 2 shows the state when the deodorizing filter is regenerated. 1 is the underframe that constitutes the air conditioner, 2 is the heat exchanger, 3 is the suction port, 4 is the blower (cross flow fan), 5 is the ventilation circuit inside the air conditioner, 6 is the outlet flap, 7 is the porous material A deodorizing filter made of activated carbon,
These are the components of a conventional air conditioner, but in the present invention, in addition to them, a heating device 8 made of a honeycomb heater is provided in front of the deodorizing filter 7, and an exhaust port 9 that connects the ventilation circuit 5 and the outdoors is provided. The exhaust port 9 is provided with an opening/closing door 11 on a fan casing 10 surrounding the ventilation circuit, and this opening/closing door is configured to be flush with the fan casing when opened. 9 is guided to the outside through the wall 12, and an exhaust fan 13 is attached in contact with the outer wall.With the above configuration, as shown in FIG.
is closed, and the outlet flap 6 is opened to allow normal air conditioning operation. If the deodorizing function of the deodorizing filter deteriorates due to repeated indoor deodorization, the filter regeneration operation shown in Figure 2 is performed. During this operation, normal air conditioning operation is stopped. The opening/closing door 11 of the exhaust port 9 is opened.When the honeycomb heater 8 is energized and the temperature of the deodorizing filter 7 reaches 100°C to 150°C, the adsorbed odor is desorbed. 5. By operating the exhaust fan 13, this odor is exhausted outside.

After several minutes of operation, the regeneration of the deodorizing filter 7 is completed and the deodorizing function returns to its original state. Thereafter, normal air conditioning operation can be performed again in the state shown in FIG. In this example, the deodorizing filter can be an adsorption type deodorizing filter made of activated carbon such as zeolite.Furthermore, it is not an adsorption type deodorizing filter that reacts with odors using a ceramic catalyst. However, as the catalytic reaction progresses, the deodorizing function decreases.This type of filter can also be used because it is heated and regenerated in order to restore the deodorizing function.Also, to exhaust odors, an exhaust fan is installed outside the room. If the configuration is properly configured, the air can be exhausted only by the blower of the air conditioner. Effects of the Invention The present invention makes it possible to reuse the deodorizing filter, and it is easy to use because there is no need to replace the deodorizing filter. Not only is it good, but it also has great cost advantages (X).Also, it can always maintain a good deodorizing function, so it can provide a comfortable living space.
