Description

[Detailed Description of the Invention] [Technical Field] This invention relates to an air conditioner with an air purifying function for use in places 6 that emit cigarette smoke and various other odors (unpleasant odors), such as ordinary homes and offices. It is.

[Background technology]

As equipment to improve the environment in living rooms, air conditioners are generally used to improve the temperature, and air purifiers are used to reduce air pollution. In particular, the latter is becoming increasingly popular in ordinary households, as seen in recent years with the right to quit smoking.

When installing these devices in a living room in a general household, for example, a 6 to 8 tatami room, conventionally each had to be installed separately, and from an electrical construction perspective, it was necessary to insert the cord cap into each separate outlet. Not only is this extremely troublesome, the installation work is doubled, but it also spoils the aesthetics (interior). Furthermore, these devices are often used in a wall-mounted form in order to use a large floor space. In this case as well, to install the two devices separately,
Mounting metal fittings, nails, etc. must be added unnecessarily. In addition, there is a lack of uniformity in terms of design, with two similar devices (having the common function of circulating indoor air to improve the living space environment).
It is not aesthetically pleasing to have separate walls on the wall.

Furthermore, as mentioned above, in order to smoothly circulate indoor air, the discharge and suction ports of these two devices (
It is desirable to have a common outlet (or at least a discharge port) or to place them close together so that the air flows of each device do not cancel each other out.

On the other hand, if we compare the characteristics of these two types of ventilation systems, (a) The air conditioner has a relatively large amount of air, and the ventilation resistance is mainly caused by the heat exchanger, and its value is relatively small. Therefore, it is desirable that the blower be able to generate a larger amount of air than the static pressure.

(3) (B) Contrary to the above, since air purifiers mainly consist of air filters, the ventilation resistance is relatively large, and air conditioners do not need to be very large in terms of circulating air volume. For this reason, it is desirable that the blower be of a type that can maintain a large amount of static pressure with a moderate amount of air.

In any case, it is not very desirable to separately install two similar devices in a small living room. It is desirable to incorporate functions and share installation work, electrical work, ventilation mechanisms, etc.

[Purpose of the invention]

This invention has an air purifying function and a heating/cooling function, and compared to installing two devices each having these functions separately, this invention reduces the number of parts, simplifies installation work, improves circulation efficiency,
The purpose of the present invention is to provide an air conditioner with an air purifying function that saves space and improves the appearance.

[Disclosure of the invention]

The air conditioner with an air purifying function of the present invention includes a motor pump, an air purifying filter, and a heat exchanger for heating or cooling the air, in the air passage of a housing having a suction (4) inlet and an outlet. It houses the vessels.

Embodiment An embodiment of the present invention is shown in FIGS. 1 to 7. In the figure, ■ is the housing, with 2111 at the bottom of the front.
The suction ports 2 and 3 of i1 are arranged side by side, and one wide discharge port 4 is formed in the upper part of the front surface. Inside the housing 1, a partition wall 5 provided between both suction ports 2.
Two ventilation passages 6, 7 (FIG. 3) are formed, and these ventilation passages 6, 7 communicate at the upper part and share the discharge port 4. Fans 8 and 9 are provided above each of the air passages 6 and 7, respectively, and these fans 8 and 9 are respectively attached to output shafts protruding from both sides of one motor 10. A filter 18 is provided in one of the air passages 6, and a heat exchanger 11 is provided in the other air passage 7, facing the suction ports 2 and 3, respectively.

The filter 18 generally has a particle size of 1
Particulate matter with a size of 0 μ or more, and has the ability to remove (5) cigarette smoke, etc.

Filters for dust removal and deodorization may be provided in layers.

The heat exchanger 11 is of a heat pump type or the like, and the heat pump main body including the compressor is not shown.

A damper 12 is provided in the air passage 7 on the side of the heat exchanger 11, and is located on the back side of the heat exchanger 11 and serves as an air passage switching means. The damper 12 is rotatably mounted around a support shaft 13 at the lower end. The damper 12 is connected to a switching motor 14, and the motor 14 is controlled by a switch SW that is opened and closed by a sensor 15.

(Fig. 5). In addition, the switching motor 14
An electromagnetic solenoid may be used instead.

The sensor 15 consists of a smoke/gas sensor that detects contaminated air. FIG. 5 shows the entire electrical circuit. 17 is an AC power source. Switches sw, sw', sw.

is a manual type, and the switch SW is provided on the front of the housing 1. The switches sw and sw' are opened and closed in conjunction with each other.

Operation (6) In FIG. 3, FIG. 6A, and FIG. 7(A), both the air cleaning function and the heating/cooling air conditioner 0 are working, and the damper 12 is closed. Indoor air is supplied through both intake ports 2,
It is sucked in from 3. The air flowing in from each suction port 2.3 is purified by a filter 18 or heat exchanged by a heat exchanger 11, and then merged and discharged into the room from a discharge port 4.

In FIGS. 4, 6(B), and 7(B), only the air cleaning function is operating, and the damper 12 is open. In this case, air flows in only from the suction port 2 on the side of the filter 18 and is discharged from the discharge port 4.

The damper 12 is opened and closed by the motor 1 based on the signal from the sensor 15.
It will be held in 4. That is, when the indoor air becomes polluted due to cigarette smoke, etc., the sensor 15 detects it and the damper 12
closes.

The reason for operating the damper 12 in this manner is as follows. Generally, the filter 18 is capable of removing fine particles, and it is desirable to use a blower that has relatively large ventilation resistance (pressure (7) loss) and generates large static pressure. The heat exchanger 11 used for heating and cooling has lower ventilation resistance than the filter 18. However, in order to quickly perform heating or cooling, it is desirable to have a large amount of air flow.

From these points of view, when the indoor air is not very polluted, the heating and cooling function is mainly used, and when the indoor air becomes polluted, the air purification function is put into operation.

It operates in this way, but since both the means for obtaining air purification function and the means for obtaining air conditioning are incorporated into one housing 1, it is possible to install two separate devices with each function. Compared to the previous version, parts can be shared, fewer parts are required, and the installation work (installation work, electrical work, etc.) is only needed for one unit, making it easier to perform. Also, one housing]
, so if you install it, you can create a living room that is aesthetically pleasing from an interior perspective.

In addition, since two types of air circulation functions are installed in one housing 1, uniformity is created in the indoor air circulation (8), and indoor air circulation is performed efficiently and comfortable. Environmental conditions are easier to maintain.

Moreover, since the outlet 4 for the air passing through the filter 18 and the air passing through the heat exchanger 11 are common, both types of air are mixed inside the machine and exit, resulting in comfortable air conditioning. (If the two are provided separately, the air coming out of each outlet will be mixed indoors, so in the case of heating, for example, the air from the filter will be cold air, making it impossible to obtain comfortable heating.) Since the two functional means are integrated into one housing 1, there are some common parts, so the overall volume of the device can be made compact, and it can be used as widely as possible even in a small room. Further, by providing a switching means for both functions, the function of the device can be effectively exhibited according to the environmental condition of the room at that time, and a comfortable environment can be maintained efficiently. Moreover, since the switching means (damper 12) is automatically activated by the sensor 15, a comfortable living environment can be realized efficiently and without any hassle.
