Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an air conditioner with an air purifying function used in general homes, offices, and the like.

[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. Especially the latter,
Recently, as seen in the right to quit smoking, it is becoming more common in ordinary households.

When installing these devices in a room in a general household, for example, a 6 to 8 tatami room, conventionally each had to be installed separately, and from an electrical work point of view,
Each cord cap has to be plugged into a separate outlet, which is not only very cumbersome, but also requires double installation work, and 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, in order to mount the two devices separately, mounting metal fittings, nails, etc. must be unnecessarily attached. In addition, there is a lack of uniformity in terms of design, and two similar devices (which have the common function of circulating indoor air to improve the living space environment) are placed on the wall. Providing them separately is not aesthetically pleasing either.

Furthermore, as mentioned above, in order to circulate indoor air smoothly, the discharge port and suction port (at least the discharge port) of these two devices should be made common.
Alternatively, it is preferable to place them close together so that the airflows of each device do not cancel each other out.

On the other hand, when comparing 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 due to 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.

(b) Contrary to the above, since air purifiers mainly include air filters, the ventilation resistance is relatively large, and the circulating air volume does not have to be as large as that of air conditioners. 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.

The same problems as above arise when an air purifier and a circulator for circulating air in a single room are provided.

[Purpose of the invention]

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

[Disclosure of the invention]

The air conditioner with an air purifying function of this invention has two
A housing having two air ducts inside is provided, an air purifying filter is provided in one of the air ducts, and an air duct switching means is provided to selectively open and close both air ducts or to open and close either one of the air ducts. It is something.
The other air passage may be provided with a heat exchanger and used for heating and cooling, or may be used simply for air circulation without any provision.

Embodiment An embodiment of the present invention is shown in FIGS. 1 to 7. In the figure, 1 is a housing, in which two suction ports 2 and 3 are provided side by side at the lower part of the front surface, and one wide discharge port 4 is formed at the upper part of the front surface. Inside the housing 1, two air channels 6 and 7 are formed by a partition wall 5 provided between both suction ports 2 and 3.
(FIG. 3), these air passages 6 and 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 of one motor 10 that protrude on both sides. A filter 18 is installed in one air passage 6, and a heat exchanger 11 is installed in the other air passage 7, respectively.
It is located facing 3. The filter 18 is generally capable of removing airborne dust (particulate matter with a particle size of 10 μm or less, such as cigarette smoke). 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.

The heat exchanger 11 is installed in the air passage 7 on the heat exchanger 11 side.
A damper 12 is located on the back side of the
is provided. The damper 12 is attached to a support shaft 13 at the lower end.
It is mounted so that it can rotate freely. Damper 12
is connected to the switching motor 14, and the motor 1
4 is controlled by switch SW ₀ , which is opened and closed by sensor 15.
(Fig. 5). Note that an electromagnetic solenoid may be used instead of the switching motor 14.
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 ₁ are manual, and switch SW is housing 1.
It is located on the front of the Switches SW and SW' open and close in conjunction.

Operation In FIG. 3, FIG. 6A, and FIG. 7A, both the air cleaning function and the heating/cooling air conditioning function are working, and the damper 12 is closed. Indoor air is sucked in from both suction ports 2 and 3. Each suction port 2,
The air flowing in from 3 is purified by a filter 18 or heat exchanged by a heat exchanger 11, and then combined and discharged into the room from a discharge port 4.

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

The damper 12 is opened and closed by a motor 14 based on a signal from a sensor 15. In other words, if the indoor air becomes polluted due to cigarette smoke, etc., the sensor 15
is detected and the damper 12 opens.

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 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.

Although it operates in this way, 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. Moreover, since it is contained in one housing 1, when this is installed, a living room with excellent aesthetic appearance can be realized from an interior aspect. In addition, one that has two air circulation functions is
Since it is housed and installed in one housing 1, there is uniformity in indoor air circulation, efficient indoor air circulation, and a comfortable environmental condition is easily maintained. 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, thereby providing comfortable air conditioning. (If the two are installed 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 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.

FIGS. 8 and 9 show a second embodiment.
In this example, a suction port 22 is provided at the bottom of the housing 21.
One discharge port 23 is provided in the upper part of each of the discharge ports 23. A partition plate 25 is provided in the center of the housing 1, and a filter 18 is placed between the partition plate 25 and the front wall.
A heat exchanger 11 is disposed between the heat exchanger 5 and the rear wall.
The area from the bottom surface of the filter 18 to the suction port 22 is the first air passage 6-2, and the area from the bottom surface of the heat exchanger 11 to the suction port 22 is the second air passage 7-2. -2 and 7-2 are gathered at the upper surface of the filter 18 and the heat exchanger 11 and continue to the discharge port 23. A fan 26 is arranged in the collective air path portion. A damper 27 serving as an air path switching means is attached to the lower end of the partition wall 25 so as to be rotatable around a horizontal support shaft 28. 29 and 30 are damper 2
This is a stopper that engages with 7. The damper 27 is connected to a manual switching knob 28 protruding from the side surface of the housing 21. Sw is a switch for opening and closing the power supply for the motor of the fan 26.

In this configuration, when the damper 27 is set to the neutral position _A2 as shown by the solid line in Fig. 9, air is blown to the air passages 6-2 and 7-2 on both sides, performing both air purification and heating/cooling functions. is obtained. When the damper 27 is placed in the vertical position _A1 , the air passage 6 on the filter 18 side
Air is blown only to 2, and only the air purifying function can be obtained. When the damper 27 is placed in the horizontal position _A3 , air is blown only to the air passage 7-2 on the heat exchanger 11 side.
Only heating and cooling functions are available. The rest is the same as the first embodiment.

FIGS. 10 and 11 show a third embodiment. In this example, one discharge port 32 and one suction port 33 are provided on the upper and lower front surfaces of a housing 31, and a heat exchanger 11 and a filter 18 are arranged diagonally vertically in the housing 1. In this case, suction port 3
The air passage 6 has one space from 3 to the filter 18.
-3, and the space from the suction port 33 to the heat exchanger 11 passing below the filter 18 becomes another air blowing path 7-3. Both air passages 6-3 and 7-3 communicate with each other at the rear surface of the filter 18. The air passage 7-3 on the side of the heat exchanger 11 is opened and closed by a damper 35 attached to the support shaft 34 so as to be movable up and down. 36
is a fan, and 37 is an operation knob for the damper 35.

With this configuration, when the damper 35 is set to the open position _B1 , almost no air passes through the filter 18, and only the heat exchanger 11 passes through. When the damper 35 is in the closed position _B2 , air passes through the filter 18 and the heat exchanger 11 in sequence. The rest is the same as the first embodiment.

FIGS. 12 to 14 show a fourth embodiment. In this example, a discharge port 42 and a suction port 43 are provided on the upper and lower front surfaces of the housing 41, respectively, and a second suction port 44 is provided on the lower surface. Inside the housing 1, a filter 18 is provided facing the suction port 43, and a heat exchanger 11 is provided in the inner part.
Side ventilation passage 6-4 and heat exchanger 11 side ventilation passage 7-
4 are arranged in series and communicated through a communication portion 47. 45 is the main fan, 48 is the filter 18
This is a cleaning fan provided in the side air passage, and is attached to the motor 49. The second suction port 44 is arranged near the communication portion 47, and a damper 5 that selectively opens and closes the second suction port 44 and the communication portion 47 is provided.
0 is provided rotatably around a support shaft 51.
The damper 50 is connected to a switching motor 52 (FIG. 14). An electromagnetic solenoid may be used instead of the switching motor 52. Each fan 45, 48 has a motor 46, 49 and a switching motor 52.
Connected as shown. SW, SW ₁ ′, SW ₂ ′,
SW ₀ ′ is a switch. The switch SW ₀ ' of the switching motor 52 is opened and closed by a signal from the sensor 53. The switches SW ₁ ′ and SW ₂ ′ may be manual, or may be relay circuits that operate in conjunction with the operation of the sensor 53 like the switch SW ₀ ′. Sensor 53 is a temperature sensor.

With this configuration, when the damper 50 closes the second suction port 44 (solid line position),
The main fan 45 and the cleaning fan 48 operate together,
Air sucked through the suction port 43 passes through the filter 18 and the heat exchanger 11 in sequence and is discharged. When the damper 50 opens the second suction port 44 (the position indicated by the chain line), only the main fan 45 operates, and the air entering from the second suction port 44 passes through the heat exchanger 11 and reaches the discharge port 42. It is discharged from. The damper 50 is opened and closed by detecting the room temperature by a sensor 53. During cooling, when the room temperature rises, sensor 5
damper 50 so as to close the air passage 6-4 on the filter 18 side and open the second suction port 44.
Rotate. At the same time, the compressor and the like of the heat exchanger 11 are also driven. When the room temperature becomes lower than the set value, the damper 50 closes the second suction port 4.
It operates to close 4. The rest is the same as the first embodiment.

15 to 17 show a fifth embodiment. In this example, a discharge port 6 is provided on the top surface of the housing 61.
2 and a filter unit 6 on the front.
3 is provided so as to be freely drawn out, and a first suction port 64 is provided on the front surface of the filter unit 63. The filter unit 63 has the filter 1 in the first suction port 64.
8, and a second one is provided at the part that goes in and out of the housing 61 as the filter unit 63 goes in and out.
A suction port 65 is provided. A handle 66 is provided on the filter unit 63. A fan 68 is provided in the center of the housing 61, and a heat exchanger 11 is provided near the discharge port 62. In this example, the inside of the filter unit 63 is the filter 18.
The inside of the housing 61 becomes the ventilation path 7-5 on the side of the heat exchanger 11.

In this case, as shown in FIG. 17A, by pulling the filter unit 63 forward, the second suction port 65 opens, and when the fan 68 is driven, air is sucked in from the second suction port 65. It is then discharged from the discharge port 62 through the heat exchanger 11. As shown in FIG. 17B, the filter unit 63
When pushed in, the second suction port 65 is closed, and air is sucked from the first suction port 64 through the filter 18 by the drive of the fan 68, and the heat exchanger 11
It is discharged from the discharge port 62 through. In this case, both air cleaning and air conditioning by heat exchange are performed. The rest is the same as the first embodiment.

FIGS. 18 and 19 show the sixth embodiment. This example can be used as an air cleaner or a circulator. In this example, a discharge port 72 and a suction port 73 are provided at the top and bottom of the front surface of the housing 71, and the filter 18 is provided in the middle portion toward the front. 74 is Juan. At the lower edge of the filter 18, the air passage 6-6 on the filter 18 side
A damper 75 is rotatably provided to selectively open and close the air passage 7-6 that does not pass through the filter 18. The damper 75 is connected to a switching knob 76.

In this configuration, the damper 75 functions as an air purifier at the position C ₁ where it completely closes the air passage 7-6, and moves from the neutral position C ₂ to the position C ₃ where it closes the air passage 6-6 on the filter 18 side. As the filter 18 moves, the amount of wind passing through the filter 18 decreases, and the filter 18 becomes effective as a circulator.

[Effects of the Invention] The air conditioner with an air purification function of the present invention has an air purification function and an air circulation function, and reduces the number of parts compared to the case where two devices each having these functions are installed. It has the effect of simplifying installation work, improving circulation efficiency, saving space, and improving appearance.
