JPH081322B2 - Aroma generator built into the air conditioner - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention incorporates an fragrance generator into an air conditioner, and the fragrance generator is incorporated into an air conditioner that can be used to control the environment of a living space. It is about.

<Prior Art> Conventional air conditioners are targeted for temperature, humidity, dust concentration, CO ₂ concentration, etc. of a living space. Therefore, the removal of odors generated from tobacco, human bodies, building materials, etc. is mainly due to the filter effect of activated carbon or the effect of diluting fresh air.

Further, as an object of which an odor masking effect is aimed, a fragrance for a table and the like can be cited as an object of expecting an effect in a limited range.

<Problems to be Solved by the Invention> Among the above-mentioned conventional ones, the one using a filter such as activated carbon has a short life and the price of the filter itself is expensive.

In addition, since the method by dilution introduces a large amount of fresh air (outside air), a large amount of energy is required for cooling or heating this air.

On the other hand, the method using an aromatic agent has no problem as in the above method, but its diffusing power is weak, so that the effect can be expected only in a small room or the like, and the application range is limited.

The present invention has been proposed in view of the above points, and even in a wide space such as an office, it is possible to control the environment and create a favorable habitability with rich humanity. Is to provide.

<Means for Solving Problems> In order to solve the above problems, the present invention provides a perfume spray nozzle in the air flow passage of an air conditioner equipped with a heat exchanger and a blower, and provides the same perfume spray nozzle. The aroma generating device is characterized by comprising a liquid flavor cylinder and a pipe for supplying the liquid flavor, and a spray amount control valve provided in the pipe and controlled by a control unit.

<Operation> According to the above configuration, by opening / closing and opening the spray amount control valve via the control unit, the liquid perfume in the liquid perfume cylinder is sprayed through the pipe and the spray nozzle into the air flow passage of the air conditioner. Therefore, the sprayed fragrance is mixed with the conditioned air by the air conditioner, blown out into the air-conditioned space by the blower, and uniformly distributed in the entire space. Therefore, it is possible to efficiently mask unpleasant odors such as tobacco odors in the entire space.

<Embodiment> An embodiment of the present invention will be described above with reference to FIGS. 1 and 2.

This embodiment shows an example of installation in an office building, in which an air conditioner 3 including a heat exchanger 4, a blower 5 and the like is installed in an air conditioning machine room 2 in a building building 1.
Air from the office space 6 is passed through a duct 8 having a suction port and a damper 7 and outside air is provided with a damper 9.
After sucking through 10 and adjusting the temperature and humidity with the heat exchanger 4, the air is blown into the office space 6 through the duct 11 and the outlet 12 by the blower 5 to perform air conditioning in the space. The air conditioner 3 is designed so that the temperature inside the office space 6 is detected by a thermostat 13 and the humidity is detected by a humanity stat 14 and is controlled via a control unit 15.

A plurality of perfume spray nozzles 16 (three in this example) are installed in the air flow passage of the known air conditioner 3 configured as described above, and the perfume spray nozzles 16 are placed in the machine room 2. Aroma that supplies liquid fragrance from different kinds of liquid fragrance cylinders 17 through a pipe 18 and a spray amount control valve 19 provided in the pipe, and spray mixes the liquid fragrance into the air conditioned by the air conditioner 3. It constitutes the generator.

The spray amount control valve 19 is shown in FIG. 2 via the control unit 15 by the timer unit in the control unit 15, the thermostat 20 for detecting the air temperature at the outlet side of the heat exchanger 4, and the air volume signal from the blower 5. The opening and closing and the opening are controlled according to the operation flow shown.

In the above configuration, when the air conditioner 3 is in operation and the timer unit incorporated in the control unit 15 reaches a preset time, the spray amount control valve 19 corresponding to that time is opened. At the same time as outputting the signal, based on the heat exchanger outlet air temperature signal from the thermostat 20 and the air volume signal from the blower 5, the spray amount is calculated from the relational data set in advance as shown in FIG. The control valve 19 is adjusted to an opening degree according to On the other hand, when the control valve 19 is opened, the timer is set, and during the set time, the liquid perfume is sprayed from the spray nozzle 16 into the air conditioned by the heat exchanger 4 and mixed in the air, and the duct 11 is blown by the blower 5. Then, it is blown out into the office space 6 through the air outlet 12 to control the temperature and scent of the office space and mask the unpleasant odor.

It should be noted that the time, time, amount, and type of the fragrance to be sprayed are automatically controlled according to a pre-installed program, so, for example, in an office space, it can be divided into the start time, lunch time, and end time, which are suitable for each. It can also be used for the purpose of releasing the scent so as to stabilize and enhance the spirit.

<Effects of the Invention> As is clear from the above, according to the present invention, it is possible to control the environment even in a wide space such as an office space, so that unpleasant odors are masked and good habitability is created. It is possible to improve the efficiency of office work by stabilizing and raising the spirit of residents.

Also, because it is built into the air conditioner, it can be manufactured at low cost, and since the fragrance is sprayed and blown into the conditioned air by the air conditioner, the scent is evenly distributed throughout the office. You can

In addition, since the spray amount of the fragrance is controlled according to the air volume and the air temperature, the concentration can be kept constant, and since a plurality of fragrance cylinders of different types are provided, an appropriate fragrance can be obtained depending on the situation. Can be released.
