Abstract

The invention discloses a fresh air air conditioner PM2.5 purification automatic cleaning device, comprising an air passage arranged between a return air inlet and an air outlet of an indoor unit of an air conditioner or an air purifier and an air valve device arranged in the air passage, wherein the wind shield of the air valve device is an air purification integrated module (1). The device can be directly connected to the air outlet or air inlet of an indoor unit of an existing air conditioner by a hose, and can purify indoor air while heating or cooling. Since the fresh air outlet is sealed and placed on the air inlet surface of the heat exchanger of the indoor unit of the air conditioner, the problem of reducing the indoor circulating air volume of the air conditioner is increased. When the air needs to be purified, the purification mode can be turned on. The problem of increasing the wind resistance and reducing the circulating air volume due to the installation of the purification module is overcome. The air is purified while heating and cooling, and the heating and cooling capacity is basically not affected. When strong and rapid heating and cooling are performed, the purification module is closed, and the indoor air is temporarily not purified. There is no wind resistance, but since the fresh air is sent to the air inlet surface of the heat exchanger, the entire circulating air volume is increased due to the entry of the fresh air, and the fresh air volume is about 20% of the design air volume of the indoor unit of the air conditioner.

When the air valve device is closed, the air circulation wind must pass through the purification module A and the purification module B to achieve the purpose of purifying the air.

When the air valve device is opened, there is a gap between the upper side wall of the purification module A and the inner wall of the air passage, and there is a gap between the lower side wall of the purification module B and the inner wall of the air passage; the driving device is a controllable motor. At this time, there is no wind resistance to the air circulation wind, so the air volume increases.

Specifically, the fresh air air conditioner PM2.5 purification automatic cleaning device includes the air outlet A facing the air inlet surface of the heat exchanger of the air conditioner, the air valve device arranged in the air passage, and the damper of the air valve device. The wind panel is an air purification integrated module.

In the present invention, the air purification integrated module is used as the windshield of the air valve device. When the air needs to be purified, the purification mode is started, that is, the air purification integrated module used as the windshield is driven by the driving device to close the air passage, and the air The purification integrated module is blocked in the air passage. The general air purification integrated module is mainly composed of high-efficiency filters, activated carbon layers, nano-photocatalytic nets, or other purification devices. Air can circulate through the air purification integrated module. At this time, the air is in the Driven by the fan, it flows through the air purification integrated module to complete the high-efficiency filtration of air. When the temperature is extremely high or extremely low, rapid cooling or heating is required. At this time, the powerful cooling and heating mode is turned on. At this time, the air purification integrated module as a windshield will be driven by the driving device. The air passage is opened. At this time, the air purification integrated module is completely parallel to the air passage on the path of the air passage. The air passes quickly under the urging of the fan, the wind resistance is reduced, and the air volume is increased. It can be completed in a short time Cooling and heating, at this time, the heating and cooling efficiency and air outlet speed are about 20% higher than before the device is not added, and the heating and cooling capacity is increased by about 20%, because when the fresh air device is connected, the fresh air directly enters the heat exchanger of the air conditioner the air intake side.

In the above working mode, the purification function cannot be performed during rapid cooling and heating. In order to solve this problem, the present invention also includes a fresh air device with the air outlet B facing the air inlet surface of the heat exchanger of the air conditioner.

Generally, the number of air inlets B is 2, one is connected to the outdoor, and the other is connected to the indoor. The air that is connected to the room is introduced into the room, and the fresh air that is connected to the outside is introduced from the outside.

On the basis of the above-mentioned device, a fresh air device is also added. The air outlet B is the air outlet of the fresh air passage, and the air outlet sends fresh air into the room. After the fresh air device cooperates with the above-mentioned device, the above-mentioned shortcomings can be avoided. Air outlet B can introduce indoor air and outdoor air at the same time or separately. Air inlet B and air outlet B are respectively equipped with controllable air valves for opening and closing. In fresh air supply mode, air inlet B is opened to introduce fresh air. Due to the presence of fresh air motor The fresh air is driven and introduced, and the outlet of the fresh air is directly on the air intake surface of the heat exchanger. Therefore, the air supply volume of the entire air conditioner is basically unchanged or higher than the original one. When the purification mode is turned off, the air supply volume and cooling and heating efficiency are larger than the original equipment, and the heating and cooling capacity is higher. Therefore, after adding the fresh air device, the purification mode and the cooling and heating mode can coexist. The fresh air device and the air passage coexist separately, but the outlet air of the fresh air device must be sealed and enter the air inlet surface of the heat exchanger to increase the circulating air volume of the air conditioner.

For the present invention, there are two design methods of the air purification integrated module, that is, the design method when the number of the air purification integrated module is 1 or the design method when the number of the air purification integrated module is 2, wherein, when the number is 1 The first design method has lower cost and lighter weight, and is suitable for air-conditioning equipment with a smaller power, while the second design method with a number of 2 is more suitable for air-conditioning equipment with a larger air volume.

The specific structures of the two designs are now described in detail.

When the number of air purification integrated modules is 1, one end of the air purification integrated module is connected to the inner wall of the air passage through a hinge, a flap or a rotating shaft, and the other end of the air purification integrated module is connected to the output shaft of the driving device.

When the air valve device is opened, the upper side wall of the air purification integrated module is attached to the inner wall of the air passage or the upper side wall of the air purification integrated module is parallel to the inner wall of the air passage; when the air valve device is closed, the air purification integrated module The upper side wall gradually moves away from the inner wall of the air passage until the lower side wall of the integrated air purification module touches the inner wall of the air passage.

When the air valve device is closed, the crosspiece of the air purification integrated module is on the path of the air passage, at this time, the air can flow through the air purification integrated module, and the air outlet speed at this time is small, but the air can be filtered efficiently. When the air valve device is opened, there is no obstruction in the air passage, the air can flow directly through, and the air outlet speed is very high, which is suitable for the time when rapid cooling and heating are required.

Generally, the air passage is a hollow rectangular pipe, and one end of the air purification integrated module is connected to the upper inner wall of the air passage through a hinge, a flap or a rotating shaft, and the output shaft of the driving device drives the air purification integrated module to rotate around the hinge or the hinge. Or turn the axis for movement.

When the number of air purification integrated modules is 2, the air purification integrated module is divided into purification module A and purification module B, and the drive device is divided into drive device A and drive device B. One end of purification module A and one end of purification module B are connected through a hinge The other end of the purification module A is connected with the output shaft of the driving device A, and the other end of the purification module B is connected with the output shaft of the driving device B.

When the air valve device is opened, the lower side wall of the purification module A and the upper side wall 101 of the purification module B are attached to each other; when the damper device is closed, the lower side wall of the purification module A is separated from the upper side wall 101 of the purification module B, The upper side wall 101 of the purification module A moves toward the inner wall of the air passage until it touches the inner wall of the air passage, and the lower side wall of the purification module B moves toward the inner wall of the air passage until it touches the inner wall of the air passage. Module A and purification module B form a V-shape or a pocket shape.

When the air valve device is opened, there is a gap between the upper side wall 101 of the purification module A and the inner wall of the air passage, and there is a gap between the lower side wall of the purification module B and the inner wall of the air passage.

The driving device is a controllable motor.

The purification part and fresh air device are suitable for air duct machines, ceiling machines, cassette machines, fan coil units, air cabinets, household machines, and commercial machines. The fan of the fresh air device can also be made into a full heat exchanger, or it can be a single fan. There is a bottomless dust sweeping cavity in the air passage, and the opening direction of the dust sweeping cavity faces the air inlet surface of the air purification integrated module. The dust sweeping cavity is provided with 2 ports, and air valves are installed in the 2 ports , A dust sweeping device is arranged in the dust sweeping cavity. One of the ports is connected to the dust removal channel, and a fan is arranged in the dust removal channel, and the other port is connected to the air outlet B of the fresh air device, and a valve is arranged in the dust removal channel. The dust-sweeping cavity is connected with a dust-removing channel, and the dust-removing channel is provided with a fan, and the dust-sweeping cavity is provided with a dust cleaning device. The wind passing surface of the air purification integrated module is cleaned by the dust cleaning device, so that the wind passing surface is automatically cleaned. The dust removal channel and the fan form the dust removal flow channel, so that the dust is discharged. The air outlet B communicates with the dust sweeping cavity. Existing air conditioners or air purifiers with a purification layer have a single fixed structure for their purification layer. When the indoor air reaches the purpose of being purified, the heating or cooling of the air conditioner needs to continue, and the indoor wind needs to be further circulated. At this time, the purification Layer, the air resistance generated by the circulating wind, wastes electric power. The present invention sets the air purification layer as a damper. When purification is required, the purification layer is driven by a controllable motor to close the circulation air channel, and the circulation air passes through the purification layer. , the circulating air is purified. When the indoor air reaches cleanliness, the purification layer is driven by a controllable motor to open the circulating air duct, and the circulating air passes through the gap formed between the purification layer and the wall of the circulating air duct, and the purification layer will not cause any wind resistance to the circulating air. To achieve the purpose of energy saving, the existing air purifiers or indoor air conditioners with purification devices have a single purification method, and cannot selectively purify indoor air and outdoor fresh air according to needs, which wastes a lot of energy. The present invention uses a controllable motor , and the purification layer is set as a damper, so that the same purification layer can purify both indoor air and outdoor fresh air. When the indoor air purification reaches the set value, or when the air conditioner indoor unit needs strong cooling and heating, it can also be selected Only the outdoor fresh air is purified, so that the indoor unit of the air conditioner does not increase the power of the fan, and it can also achieve fresh air purification and indoor air purification, and has no effect on the heating and cooling of the air conditioner. The indoor clean air is no longer purified, which achieves the purpose of saving energy and reducing equipment costs, and realizes ventilation without opening windows, and the indoor air is always clean and comfortable.

The advantage of the present invention is that the device can be directly connected with the air outlet or air inlet of the existing air conditioning equipment and indoor unit with a hose, and can purify the indoor air while heating or cooling, because the fresh air outlet is sealed and placed inside the air conditioner The air inlet surface of the heat exchanger increases the problem of reduced circulating air volume in the air-conditioning room. When the air needs to be purified, the purification mode can be turned on. It overcomes the problem of adding a purification module to increase the wind resistance and reduce the circulating air volume. While heating and cooling, it purifies the air at the same time, which basically has no effect on the heating and cooling capacity. When the heating and cooling are strong and fast, the purification module is closed, and the indoor air is not purified temporarily, and there is no wind resistance. But because the fresh air is sent to the air inlet side of the heat exchanger, the whole circulating air volume is increased due to the fresh air entering. The fresh air volume is about 20% of the designed air volume of the indoor unit of the air conditioner. Therefore, the heating and cooling capacity is also increased by 20% compared with the original design. Left and right, heating and cooling are faster than the original design. When the indoor temperature is adjusted to a certain temperature range, in order to keep the indoor temperature basically unchanged, the air conditioner can purify the indoor air while heating and cooling. It can also purify the indoor during the spring and autumn transitional seasons Air, no cooling and heating, no restrictions on air conditioning, no breeding of bacteria.

When the air valve device is opened, the upper side wall 101 of the air purification integrated module 1 is parallel to the inner wall of the air passage, and there is a gap between the air purification integrated module 1 and the inner wall of the air passage; when the air valve device is closed, the air purification integrated module 1 The upper side wall 101 of the upper side wall 101 gradually moves away from the inner wall of the air passage until the lower side wall 102 of the air purification integrated module 1 touches the inner wall of the air passage. At this time, the crosspiece of the air purification integrated module 1 is in the air passage and closes the air passage. When the air valve device is opened, the air circulation wind passes through the gap between the integrated air purification module 1 and the inner wall of the air passage, and the integrated air purification module 1 does not generate wind resistance at this time. When the above damper device is closed, since the air purification integrated module 1 crosspieces on the air passage, at this time, the air circulation wind must pass through the air purification integrated module 1, so as to achieve the purpose of purifying the air.

When the number of air purification integrated modules 1 is 2, the air purification integrated module 1 is divided into purification module A11 and purification module B12, the drive device 2 is divided into drive device A21 and drive device B22, one end of the purification module A11 and the purification module B12 One end is connected by a hinge, a flap or a rotating shaft, the other end of the purification module A11 is connected with the output shaft of the driving device A21, and the other end of the purification module B12 is connected with the output shaft of the driving device B22.

When the air valve device was opened, the lower side wall of the purification module A11 and the upper side wall 101 of the purification module B12 were attached to each other; when the damper device was closed, the lower side wall 102 of the purification module A11 and the upper side wall 101 of the purification module B12 Separated, the upper side wall 101 of the purification module A11 moves toward the inner wall of the air passage until it touches the inner wall of the air passage, and the lower side wall of the purification module B12 moves toward the inner wall of the air passage until it touches the inner wall of the air passage. The time purification module A11 and the purification module B12 form a V-shape or a pocket shape or a polygon. When the air valve device is opened, no wind resistance is generated. When the air valve device is closed, the air circulation wind must pass through the purification module A11 and the purification module B12 to achieve the purpose of purifying the air.

When the air valve device is opened, there is a gap between the upper side wall 101 of the purification module A11 and the inner wall of the air passage, and there is a gap between the lower side wall of the purification module B12 and the inner wall of the air passage; the driving device is a controllable motor. At this time, there is no wind resistance to the air circulation wind, so the air volume increases.

Specifically, the PM2.5 purification and automatic cleaning device of the fresh air air conditioner includes the air outlet A13 facing the air passage on the air inlet surface of the heat exchanger of the air conditioner and the damper device arranged in the air passage, and the windshield of the damper device The board is an air purification integrated module 1 .

In the present invention, the air purification integrated module 1 is used as the windshield of the air valve device, and when the air needs to be purified, the purification mode is started, that is, the air purification integrated module 1 as the windshield is driven by the driving device to close the air passage The air purification integrated module 1 is blocked in the air passage. The general air purification integrated module 1 is mainly composed of high-efficiency filter screens, activated carbon layers, nano-photocatalytic nets or other purification devices. Air can circulate through the air purification integrated module 1. At this time, the air flows through the air purification integrated module 1 under the urging of the fan to complete the high-efficiency filtration of the air. When the temperature is extremely high or the temperature is extremely low, fast and powerful cooling or heating is required. At this time, the powerful cooling and heating mode is turned on. At this time, the air purification integrated module 1 as the windshield Driven to open the air passage, the air purification integrated module 1 is completely parallel to the air passage on the path of the air passage, the air passes through quickly under the urging of the fan, and the air purification integrated module does not generate any wind resistance The increase in air volume can complete cooling and heating in a short period of time. Because the fresh air device directly seals the input and output air, the heating and cooling efficiency and air output at this time are about 20% higher than before the increase of the device.

When in use, it can be realized by directly installing the device at the air inlet or air outlet of the existing air conditioner. In addition, a separate remote control commands the movement state of the air purification integrated module 1, which can realize the conversion between the purification mode of the air conditioner and the powerful cooling and heating mode, and also realizes that the air conditioner is cooling while purifying the air. And purify the indoor air. The invention breaks the disadvantages of the traditional single refrigeration and heating, and does not need to change the internal structure of the original air conditioner while increasing the air purification mode. The cost only needs to pay for the device, and you can enjoy the function of purifying the air all year round without purchasing additional air-conditioning equipment.

In addition, compared with the existing air conditioner with a purification module, the existing purification module is a fixed structure and cannot be set in motion. Therefore, the fan power of the existing air conditioner with a purification module is very large and the noise is large, which is not conducive to popularization. However, the air conditioner assembled by the present invention has the same function as the former, and has low cost and light weight, and can also be applied to existing air conditioners in use.

For the present invention, there are two design methods of the air purification integrated module 1, namely, the design method when the number of the air purification integrated module 1 is 1 or the design method when the number of the air purification integrated module 1 is 2, wherein the number When the number is 1, the cost is lower and the weight is lighter, and it is suitable for various types of air-conditioning equipment with low power, while the second design method of 2 is more suitable for air-conditioning equipment with high power.

The specific structure of the first design is now described in detail.

When the number of air purification integrated modules 1 is 1, one end of the air purification integrated module 1 is connected to the inner wall of the air passage through a hinge or flap or a rotating shaft, and the other end of the air purification integrated module 1 is connected to the output shaft of the driving device.

Until the lower side wall of the air purification integrated module 1 touches the inner wall of the air channel.

When the air valve device is closed, the air purification integrated module 1 crosspiece is on the path of the air passage. At this time, the air can flow through the air purification integrated module 1. At this time, the air output is small, but it can filter the air efficiently. . When the air valve device is opened, there is no obstacle in the air passage, the air can flow directly, and the air outlet speed is very high, which is suitable for the time when strong cooling and heating are required. The upper side wall 101 of the air purification integrated module 1 always faces the air inlet surface, that is, when the air inlet enters through the air inlet A, the upper side wall 101 of the air purification integrated module 1 faces the air inlet, and when the air outlet passes through the air inlet When A blows out, the upper side wall 101 of the air purification integrated module 1 faces away from the air inlet. This design can prevent the dust attached to the upper side wall 101 of the integrated air purification module 1 from re-entering the room when the purification module is opened.

The general air passage is a hollow rectangular pipe, and one end of the air purification integrated module 1 is connected to the inner wall of the air passage through a hinge, a flap or a rotating shaft, and the output shaft of the driving device drives the air purification integrated module 1 around the hinge or the hinge. Or turn the axis for movement.

The air purification integrated module 1 itself can be made into an S-shaped structure or other shapes, which can increase its contact area with the wind.

The driving device is a controllable motor.

In the above working mode, the purification function cannot be performed during rapid cooling and heating. In order to solve this problem, the present invention also includes a fresh air device with the air outlet B facing the air inlet surface of the heat exchanger of the air conditioner. The fresh air device includes a fresh air channel 6. At least one air inlet B62 is provided on the fresh air passage, and a fresh air motor 61 and a high-efficiency filter 64 are arranged in the fresh air passage 6; both the air inlet B62 and the air outlet B are provided with controllable air valves. The air outlet B is the air outlet of the fresh air channel. On the basis of the above-mentioned device, a fresh air device is added. After the fresh air device cooperates with the above-mentioned device, the above-mentioned shortcomings can be avoided. When it is working, the number of air inlets B62 is 2, and one air inlet B62 introduces Outdoor fresh air, one air inlet B62 introduces indoor fresh air, and the air inlet B62 and the air outlet B are respectively equipped with controllable air valves for opening and closing processing. In the fresh air supply mode, the air inlet B62 is opened to introduce fresh air. Fresh air, therefore, the air supply volume of the entire air conditioner is basically the same or higher than the original one, and the purification mode can still be activated under this condition. When the purification mode is turned on, the air supply volume is larger and the cooling and heating efficiency is higher. Therefore, after adding the fresh air device, the purification mode and the cooling and heating mode can coexist. The air passage of the fresh air device and the air passing passage exist separately in the device, and can also be welded into an integral structure. Generally, the number of air inlets B is 2, one is connected to the outdoor, and the other is connected to the indoor. The air that is connected to the room is introduced into the room, and the fresh air that is connected to the outside is introduced from the outside.

For better cooling and heating, the preferred air outlet B is located between the air inlet surface of the air conditioner internal unit heat exchanger 8 and the air outlet surface of the air conditioner fan 7, and the air outlet B is parallel to the air outlet surface of the air conditioner fan 7. In this way, the air volume and wind speed can be superimposed to increase the wind passing efficiency.

Example 2

As shown in Figure 3, Figure 4 and Figure 5.

The difference between this embodiment and Embodiment 1 is: the number of air purification integrated modules 1 is 2, when the number of air purification integrated modules 1 is 2, the air purification integrated module 1 is divided into purification module A11 and purification module B12, the driving device 2. Divided into driving device A21 and driving device B22, one end of the purification module A11 and one end of the purification module B12 are connected by hinges, flaps or rotating shafts, the other end of the purification module A11 is connected with the output shaft of the driving device A21, and the purification module B12 The other end is connected with the output shaft of the drive unit B22.

When the air valve device is opened, the lower side wall of the purification module A11 and the upper side wall 101 of the purification module B12 are attached to each other; when the damper device is closed, the lower side wall of the purification module A11 is separated from the upper side wall 101 of the purification module B12, The upper side wall 101 of the purification module A11 moves toward the inner wall of the air passage until it touches the inner wall of the air passage, and the lower side wall of the purification module B12 moves toward the inner wall of the air passage until it touches the inner wall of the air passage. The module A11 and the purification module B12 form a V shape. Preferably, the V-shaped opening formed by the purification module A11 and the purification module B12 faces the air inlet surface. That is, when the air inlet enters by the air inlet A5, then as shown in Figure 4, the V-shaped opening that the purification module A11 and the purification module B12 constitute faces the air inlet A5, if, when the air outlet is blown out by the air inlet A5, the purification The opening of the V-shaped structure formed by the module A11 and the purification module B12 faces away from the air inlet A5. This design can prevent the dust attached to the opening surface of the V-shaped structure from entering the room again when filtering.

After the purification module A11 and the purification module B12 form a V shape, the air passage area of the filter structure can be increased, so the filter effect can be greatly improved.

When the air valve device is opened, there is a gap between the upper side wall 101 of the purification module A11 and the inner wall of the air passage, and there is a gap between the lower side wall of the purification module B12 and the inner wall of the air passage.

The driving device is a controllable motor.

The air purification integrated module 1 itself can be made into an S-shaped structure, that is, the purification module A11 and the purification module B12 can be made into an S-shaped structure, which can further increase their contact area with the wind.

In the above working mode, the purification function cannot be performed during rapid cooling and heating. In order to solve this problem, the present invention also includes a fresh air device with the air outlet B facing the air inlet surface of the heat exchanger of the air conditioner. The fresh air device includes a fresh air channel 6. An air inlet B62 is arranged on the fresh air channel, and a fresh air motor 61 and a high-efficiency filter 64 are arranged in the fresh air channel 6 . The air outlet B is the air outlet of the fresh air channel. The fresh air device is added on the basis of the above device. After the fresh air device cooperates with the above device, the above shortcomings can be avoided. In the fresh air supply mode, the air inlet B62 is opened to introduce fresh air. Due to the existence of the fresh air motor and Outdoor fresh air is introduced, so the air supply volume of the entire air conditioner is basically unchanged or higher than the original one. At the same time, the purification mode can still be activated under this adjustment. When the purification mode is turned on, the air supply volume is larger and the cooling and heating efficiency is higher. Therefore, after adding the fresh air device, the purification mode and the cooling and heating mode can coexist. The air passage of the fresh air device and the air passing passage exist separately in the device, and can also be welded into an integral structure.

For better cooling and heating, the air outlet B is located between the air inlet surface of the air conditioner internal unit heat exchanger 8 and the air outlet surface of the air conditioner fan 7, and the air outlet A is located on the air inlet surface of the air conditioner fan 7. In this way, the air volume and wind speed can be superimposed to increase the wind passing efficiency.

Based on the implementation of embodiment 1 and embodiment 2, the superior performance of the present invention is now described in conjunction with Fig. 6:

As shown in Figure 6, the comparison table of experimental parameters in Figure 6, in Figure 6, Experiment 1 is: the existing air conditioner A has no air purification function, and its air output is 1360 cubic meters per hour when the fan power is 110W.

Experiment 2 is: Example 1 adds an air purification integrated module and a fresh air device on the basis of the existing air conditioner A. When the number of the air purification integrated module 1 is 1, the fresh air air conditioner PM2.5 purification automatic cleaning device, compared with the existing There is an air conditioner A, which adds an air purification function. Although, in the powerful heating and cooling mode, the air output is 1600 cubic meters/h, but in the air purification mode, the air output is 1400 cubic meters/h. Therefore, the two modes can be switched at will, and the selectivity is very high. If the air conditioner is kept in the purification mode, there will be a waste of energy, because the indoor air will always remain at a higher level after a certain purification time. High quality condition. The air volume is increased by about 20%.

Experiment 3 is: on the basis of the existing air conditioner A, embodiment 1 increases the fresh air air conditioner PM2.5 purification automatic cleaning device when the number of air purification integrated modules 1 is 2. Compared with the existing air conditioner A, the air For the purification function, although the air output is 1,600 cubic meters/h in the powerful heating and cooling mode, the air output is 1,360 cubic meters/h in the air purification mode. Therefore, the two modes can be switched at will, and the selectivity is very high. If the air conditioner is kept in the purification mode, there will be a waste of energy, because the indoor air will always remain at a higher level after a certain purification time. High quality condition. And embodiment 1 is compared with embodiment 2, and its purifying effect is obviously that the purifying effect of embodiment 2 is better.

Experiment 4 is the existing air conditioner B with purification function. The purification structure in the existing air conditioner B with purification function is a device fixed in the air passage, so the air conditioner is always in the forced purification mode when it is working. In the cooling and heating mode, compared with the previous three experiments, the air output is 760 cubic meters per hour under the same fan, and the air output will remain at this level permanently, unless the power of the fan is increased, the air output can be increased , so that its air volume is at the same level as the previous three experiments, and at the same time, its purification effect is also at a general level.

Generally speaking, the design of the present invention can reach the unattainable technical effect of existing air conditioners. Complete the purpose of saving energy, saving and meeting market demand.

The most important feature of the present invention is that: the air outlet of the fresh air device and the air outlet of the air conditioner fan are not on the same air duct, and the wind resistance produced by the high-efficiency filter is supplemented by the air volume of the fresh air device. A bottomless dust-sweeping cavity 1111 is arranged in the air-passing passage, and the opening direction of the dust-sweeping cavity faces the air inlet surface of the air purification integrated module. A dust sweeping device 1112 is arranged in the dust sweeping cavity. The wind passing surface of the air purification integrated module is cleaned by the dust cleaning device, so that the wind passing surface is automatically cleaned. The dust removal channel and the fan form a dust removal flow channel to discharge or collect dust. The air outlet B of the fresh air device communicates with the dust sweeping cavity, and a valve is arranged in the dust removal channel. When the fresh air in the air outlet B passes through the dust-sweeping cavity and then passes through the air purification integrated module, no matter what state the air purification integrated module is in, the fresh air in this embodiment is in a purified state.

Preferably, there are two through holes in the dust sweeping cavity, one of which is a fresh air connection hole, the valve of the fresh air device is arranged in the fresh air connection hole, and the fresh air device is a commonly used air supply device. The other through hole is a dust removal connection hole, and the dust removal flow channel communicates with the dust removal connection hole. The dust removal channel is a commonly used exhaust device or fire smoke exhaust device. A valve is installed in the dust removal pipe hole.

As described above, the present invention can be well realized.
