Description

Technical Field

[0001] The present invention belongs to the technical field of air treatment components, and particularly relates to an air treatment device and an air conditioner having the same. Background Art

[0002] In winter and summer, when the outdoor temperature is relatively high, people often work and live indoors, turn on the air conditioner in a closed room, and adjust the indoor temperature to obtain a comfortable temperature suitable for the human body. In order to keep the indoor environmental temperature stable, the indoor air conditioner is often continuously used in a closed space. As the opening time continues, pollutants such as CO2, SO2, benzene, and formaldehyde accumulated indoors cannot disperse, and the concentration will exceed the safe range, affecting the indoor air quality.

[0003] In related technologies, a fresh air system or an air purifier is configured to improve the indoor air quality. However, if a disposable filter screen is used in the existing air purifier, the filter performance needs to be discarded and replaced with a new filter screen after the filter performance deteriorates, resulting in high usage costs. For the filter screen that can be regularly disassembled, the disassembly and cleaning steps are complex, and it is easy to be assembled incorrectly or dangerously during assembly after cleaning. Summary of the Invention

[0055] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0056] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "length", "upper", "lower", "front", "rear", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0057] The air treatment device 1000 according to an embodiment of the present invention will be described below with reference to the drawings of the specification.

[0058] An air treatment device 1000 according to an embodiment of the present invention, as Figure 1 shown, includes: a housing 100, a fan 200, and an air filtration adsorption desorption purification unit 300.

[0059] Among them, as Figure 3 shown, a first air duct 141, a fan chamber 142, and a second air duct 143 that are sequentially communicated are formed in the housing 100. The first air duct 141 has a first air outlet 111, and the second air duct 143 has a second air outlet 113 and an outdoor communication port 121 (the structure of the outdoor communication port 121 can be referred to Figure 2 ), and the second air outlet 113 and the outdoor communication port 121 can be switched to be opened. That is to say, when the second air outlet 113 is opened, a passage is formed between the second air outlet 113 and the first air outlet 111; when the outdoor communication port 121 is opened, a passage can be formed between the outdoor communication port 121 and the first air outlet 111.

[0060] As Figure 3 shown, the fan 200 includes a wind wheel 210 disposed in the fan chamber 142.

[0061] The air filtration adsorption desorption purification unit 300 is disposed in the housing 100. The air filtration adsorption desorption purification unit 300 has an adsorption state and a desorption state, and the outdoor communication port 121 is opened in the desorption state.

[0062] From the above structure, it can be seen that for the air treatment device 1000 according to the embodiment of the present invention, when the air treatment device 1000 is working normally, the air treatment device 1000 can purify the indoor air, and can also perform desorption regeneration on the internally provided air filtration adsorption desorption purification unit 300 to restore the purification ability.

[0063] One of the first air outlet 111 and the second air outlet 113 of the present invention can be used as the air inlet of the indoor air, and the other can be used as the air outlet of the indoor air. The present invention takes the first air outlet 111 as the air inlet of the indoor air and the second air outlet 113 as the air outlet of the indoor air as an example to illustrate the three working states of the above-mentioned air treatment device 1000:

[0064] When the air treatment device 1000 purifies the indoor air, the second air outlet 113 is opened, the outdoor connection port 121 is closed, and the fan 200 rotates forward. Driven by the fan 200, a negative pressure is formed in the fan chamber 142. At this time, the indoor air can enter the first air duct 141 from the first air outlet 111 and be purified by the air filtration, adsorption, desorption and purification unit 300. The purified air flows into the fan chamber 142 and is discharged into the second air duct 143 along with the exhaust of the fan 200, and finally is re-discharged into the room from the second air outlet 113 on the second air duct 143, thus completing the purification of the indoor air. During the purification of the indoor air, the air filtration, adsorption, desorption and purification unit 300 is in the adsorption state. That is to say, the air treatment device 1000 has an air purification mode.

[0065] As the air filtration, adsorption, desorption and purification unit 300 works in the adsorption state for a long time and the adsorption amount gradually reaches saturation, the purification ability of the air filtration, adsorption, desorption and purification unit 300 decreases. At this time, the second air outlet 113 is closed and the outdoor connection port 121 is opened. The air filtration, adsorption, desorption and purification unit 300 is in the desorption state and performs desorption regeneration. The fan 200 rotates forward and generates sufficient driving force. The desorbed pollutants in the air filtration, adsorption, desorption and purification unit 300 can be discharged to the outside through the outdoor connection port 121, so that the air filtration, adsorption, desorption and purification unit 300 restores its filtration performance. During this process, there is no need to disassemble and wash the air filtration, adsorption, desorption and purification unit 300. The air filtration, adsorption, desorption and purification unit 300 has a long service life and excellent purification performance, which can greatly improve the user experience. That is to say, in this mode, it can be regarded as a sewage discharge mode. When the air filtration, adsorption, desorption and purification unit 300 is in the desorption state, the fan 200 drives the air flow to blow from the first air outlet 111 to the outdoor connection port 121 (for the structure of the outdoor connection port 121, see Figure 2 shown).

[0066] It can be understood that, compared with the disposable filter components in the prior art, the air filtration, adsorption, desorption and purification unit 300 of the air treatment device 1000 in this application has a long service life and low comprehensive use cost; and compared with the filter components that need to be regularly disassembled and washed in the prior art, the air filtration, adsorption, desorption and purification unit 300 in this application does not need to be disassembled and washed, and the air mixed with pollutants can be quickly discharged to the outside through the air ducts and the switching of different ventilation ports provided in the air treatment device 1000. The regeneration operation is simple and efficient.

[0067] In the description of the present invention, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features, which are used to distinguish and describe features, without order or importance.

[0068] In some embodiments of the present invention, such as Figure 3 andFigure 4 As shown, the air handling device 1000 further includes: a switching damper 400 movably arranged on the housing 100. The switching damper 400 is switchable between a first position and a second position. When in the first position, the switching damper 400 blocks between the fan chamber 142 and the outdoor communication port 121 (for the structure of the outdoor communication port 121, see Figure 2 shown), and when in the second position, the switching damper 400 blocks between the fan chamber 142 and the second air outlet 113. That is to say, by providing the switching damper 400, when the switching damper 400 is in different positions, the second air outlet 113 and the outdoor communication port 121 can be respectively blocked, so as to realize different internal flow paths of the air handling device 1000 and different working states of the air handling device 1000.

[0069] Optionally, as Figure 2 shown, there may be multiple fans 200. The multiple fans 200 are arranged side by side in the fan chamber 142 (for the structure of the fan chamber 142, see Figure 3 shown), so as to improve the drainage capacity and purification speed of the fans 200. For example, in some specific examples, there are two fans 200. In the description of the present invention, unless otherwise specified, the meaning of "multiple" is two or more.

[0070] Optionally, the fan 200 is a centrifugal fan or an axial-flow fan. As Figure 2 shown, when the fan 200 is a centrifugal fan, the multiple centrifugal fans are arranged side by side at intervals along the axis direction, which is convenient for the fan 200 to intake air.

[0071] Furthermore, in the above example, the number of the fans 200 is the same as the number of the second air outlets 113 and the number of the switching dampers 400, so as to adjust different air output volumes. And each second air duct 143 can be divided into multiple ones. There are air passing openings on the multiple second air ducts 143. The number of the air passing openings is the same as the number of the second air outlets 113. The air discharged from the air passing openings converges in the communication channel 144 as Figure 3 shown, and then is uniformly discharged to the outside through the outdoor communication port 121 (for the structure of the outdoor communication port 121, see Figure 2 shown).

[0072] Optionally, the switching damper 400 realizes position switching between the first position and the second position through a switching component. The switching component (not shown in the figure) includes a motor. The motor drives the switching damper 400 to rotate and switch positions. The switching component may further include a speed reducer. The motor drives the speed reducer to move, and the speed reducer then drives the switching damper 400 to rotate so as to switch positions.

[0073] In other examples, the switching component can also be structures such as a motor and a connecting rod. The output shaft of the motor is connected to the connecting rod, and the connecting rod is connected to the switching air damper 400 and transmits the acting force of the motor to the switching air damper 400, so that the switching air damper 400 completes the position transformation. The implementation form of the position switching of the switching air damper 400 is not specifically limited here.

[0074] In some embodiments of the present invention, as Figure 2 shown, the housing 100 includes a volute 130, as Figure 5 and Figure 6 shown, the volute 130 has an enclosing plate 131, a volute tongue 132 connected to one end of the enclosing plate 131, a first diffuser plate 133 connected to the volute tongue 132, and a second diffuser plate 134 connected to the other end of the enclosing plate 131. Between the first diffuser plate 133 and the second diffuser plate 134 is the diffuser chamber 1431 of the volute 130, and the second air outlet 113 is disposed opposite to the diffuser chamber 1431.

[0075] At this time, the second air duct 143 includes a connected diffuser chamber 1431 and an outer connection chamber 1432. The outer connection chamber 1432 is located on the side of the second diffuser plate 134 away from the diffuser chamber 1431, and the outer connection chamber 1432 communicates with the outdoor connection port 121 (for the structure of the outdoor connection port 121, see Figure 2 shown). In these examples, by setting the above diffuser chamber 1431, the space behind the exhaust end of the fan 200 can be made wider, the air volume discharged through the second air outlet 113 is large, and there is sufficient air pressure to make the air discharged farther from the second air outlet 113 or the outdoor connection port 121; in addition, there is sufficient space here to set the switching air damper 400, and setting the switching air damper 400 will not affect the smoothness of air outlet, and the overall layout is sufficiently compact.

[0076] Optionally, when the switching air damper 400 is in the first position, it abuts against the second diffuser plate 134, and the end of the switching air damper 400 away from the enclosing plate 131 is located at the edge of the second air outlet 113, so that when the switching air damper 400 is in the first position, the outdoor connection port 121 is completely closed.

[0077] In the second position, one end of the switching air damper 400 abuts against the volute tongue 132 or the first diffuser plate 133, and the end of the switching air damper 400 away from the enclosing plate 131 is located at the edge of the second air outlet 113, so that when the switching air damper 400 is in the second position, the second air outlet 113 is completely closed. The end of the switching air damper 400 away from the enclosing plate 131 is located at the edge of the second air outlet 113, which is convenient for the switching air damper 400 to rotate and switch quickly with this as the rotation center when switching positions, saving the time required for movement, and the position switching of the switching air damper 400 is fast.

[0078] Advantageously, as Figure 4As shown, a first mating platform 410 is provided at one end of the switching air damper 400 close to the volute tongue 132, and a second mating platform 1311 is provided at one end of the shroud 131 close to the second pressure expanding plate 134. When the switching air damper 400 is switched to the first position, the first mating platform 410 and the second mating platform 1311 overlap each other, the position of the switching air damper 400 is stable, the switching air damper 400 completely closes the outdoor communication port 121, and the air treatment device 1000 can efficiently complete the indoor air purification without air leakage or air escape.

[0079] Optionally, the surfaces of the first mating platform 410 and the second mating platform 1311 facing each other are formed in a stepped shape, and the two stepped surfaces of the first mating platform 410 and the second mating platform 1311 are in contact and stably overlap.

[0080] Optionally, as Figure 3 and Figure 5 shown, a guide plate 135 extends from one end of the second pressure expanding plate 134 away from the shroud 131 in a direction away from the pressure expanding chamber 1431. When in the second position, the part of the switching air damper 400 away from the shroud 131 is arranged at a relative interval with the guide plate 135. In these examples, the guide plate 135 forms a certain guiding effect on the air flowing through the outer connection cavity 1432. When the second pressure expanding plate 134 is in the second position, the second pressure expanding plate 134 and the guide plate 135 arranged at a relative interval together guide the flowing air, so that the air entering from the first air inlet 111 can be quickly guided to the outdoor communication port 121, accelerating the exhaust speed, enabling the air filtration adsorption and desorption purification unit 300 to purify the indoor air when in the adsorption state, and quickly discharging the air with pollutants to the outdoor when the air filtration adsorption and desorption purification unit 300 is in the desorption state and discharges the air with pollutants.

[0081] Optionally, as Figure 5 and Figure 6 shown, a continuation plate 140 is provided at the edge of the second air inlet 113 of the housing 100. When in the first position, one end of the surface of the switching air damper 400 close to the first pressure expanding plate 133 is connected to the inner profile line of the volute 130, and the other end abuts against the continuation plate 140. Thus, when the switching air damper 400 is switched from the second position to the first position, it has a certain rotation terminal, and the continuation plate 140 provides stable support for the switching air damper 400, effectively ensuring that the switching air damper 400 is in a stable state and does not shake when in the first position.

[0082] Optionally, the switching air damper 400 is bent toward the side away from the continuation plate 140, so that after one end of the switching air damper 400 rotates by a certain angle, the other end can rotate and adjust the position faster and more flexibly, and block in front of the second air inlet 113 or the outdoor communication port 121.

[0083] Optionally, the materials of the air ducts (the first air duct 141, the second air duct 143, and the fan chamber 142) and the impeller 210 are set as antistatic materials to prevent the attached particulate matter from desorbing.

[0084] In some embodiments of the present invention, as Figure 6 shown, the air filtration adsorption and desorption purification unit 300 includes a first adsorption and desorption unit 301. The first adsorption and desorption unit 301 constitutes the second expansion plate 134. When the switching air door 400 is in the first position, it covers the first adsorption and desorption unit 301. When the switching air door 400 is in the second position, it abuts against one end of the first adsorption and desorption unit 301 away from the enclosure 131, so that the air flow passes through the first adsorption and desorption unit 301. In these examples, by setting the first adsorption and desorption unit 301, the second expansion plate 134 can be saved, and strong limiting and support can be provided for the switching air door 400 when it is in the first position; when the first adsorption and desorption unit 301 includes a heating module 330, the flowing air can be heated and then discharged, improving the temperature of the air discharged into the room.

[0085] For example, in some specific examples, when a fresh air inlet is provided on the housing 100 to introduce external fresh air, the fresh air can be heated by the heating module 330 and then discharged into the room, reducing the impact on the room temperature when introducing fresh air from the outside.

[0086] In other examples, when the outdoor connection port 121 is connected to the room through a pipeline, when the switching air door 400 is in the second position, the air entering through the first air inlet 111 can be purified by the fan 200 passing through the first adsorption and desorption unit 301 and then discharged into the room. Combined with the subsequent second adsorption and desorption unit 302, multiple filtrations of the indoor air can be realized, improving the air purification effect.

[0087] In some embodiments of the present invention, as Figure 1 shown, the housing 100 includes: an outer housing portion 110 and an inner housing portion 120. Among them, as Figure 1 shown, the outer housing portion 110 is provided with an installation opening 112, a first air inlet 111, and a second air inlet 113. The installation opening 112 and the first air inlet 111 are located on opposite sides of the outer housing portion 110. The inner housing portion 120 is detachably installed in the outer housing portion 110 from the installation opening 112, and the fan 200 is installed on the inner housing portion 120. By providing two layers of housings, namely the inner housing portion 120 and the outer housing portion 110, the opening of the internal flow channel is simplified, facilitating processing and manufacturing, and at the same time facilitating the assembly of the fan 200 on the inner housing portion 120.

[0088] Combined with Figure 1 and Figure 2 shown, the inner housing portion 120 is provided with an outdoor connection port 121 (for the structure of the outdoor connection port 121, see Figure 2As shown, it is conducive to quickly discharging the air in the fan chamber 142 through the outdoor communication port 121 or quickly sucking the air drawn into the outdoor communication port 121 into the fan chamber 142.

[0089] Optionally, the inner shell part 120 includes the structure of the volute 130 in the foregoing embodiment. As Figure 2 shown, the inner shell part 120 further includes a volute support 122. The volute support 122 is disposed around the volute 130, thereby improving the stability and strength of the volute 130. And when the volute 130 is engaged with the outer shell part 110, the volute support 122 can define the position of the volute 130 in the outer shell part 110, and finally form a stable housing 100.

[0090] Optionally, as Figure 6 shown, the air filtration adsorption and desorption purification unit 300 includes a second adsorption and desorption unit 302 provided on the outer shell part 110. The second adsorption and desorption unit 302 can quickly filter and purify the air inhaled from the first air inlet 111, so that the air flowing into the fan chamber 142 has a high cleanliness, effectively preventing the performance of the fan 200 from decreasing. Optionally, in combination with Figure 1 and Figure 6 shown, a draw port 114 is provided on the outer shell part 110 adjacent to the first air inlet 111. At least part of the second adsorption and desorption unit 302 is slidably engaged in the draw port 114. It is convenient to assemble the second adsorption and desorption unit 302 on the outer shell part 110.

[0091] Optionally, a plurality of brackets are provided between the inner walls of the outer shell part 110 at the first air inlet 111. The top of the brackets supports the second adsorption and desorption unit 302, ensuring that the second adsorption and desorption unit 302 is stably disposed at the first air inlet 111, the second adsorption and desorption unit 302 does not shake, and the brackets do not affect the air passing performance of the first air inlet 111.

[0092] In some embodiments of the present invention, as Figure 3 、 Figure 5 and Figure 6 shown, the air filtration adsorption and desorption purification unit 300 includes: an air purification filter screen 310, a regeneration catalytic module 320, and a heating module 330. The heating module 330 is disposed adjacent to the air purification filter screen 310, and the regeneration catalytic module 320 is provided on the air purification filter screen 310. The regeneration catalytic module 320 can catalytically regenerate the air purification filter screen 310, improving the regeneration speed of the air purification filter screen 310, while the heating module 330 can heat the air purification filter screen 310 and make the pollutants on the air purification filter screen 310 reach the desorption temperature and desorb, thereby restoring the filtering performance of the air purification filter screen 310.

[0093] Optionally, the air purification filter screen 310 can be a molecular sieve filter screen. For example, the molecular sieve is loaded on a metal mesh, or for another example, the molecular sieve is loaded on a ceramic fiber filter screen, so as to form a filter screen with stable structure and excellent filtering performance. At normal temperature, the air purification filter screen 310 works normally and adsorbs pollution particles such as particulate matters, sulfides, nitrides, dust, and lint. When the air purification filter screen 310 is catalyzed by the regeneration catalytic module 320 and heated by the heating module 330, the pollutants adsorbed on the air purification filter screen 310 are desorbed.

[0094] Optionally, the heating module 330 includes a PTC module. After the PTC module is turned on, it can make the pollutants attached to the air purification filter screen 310 reach the desorption temperature or the decomposition temperature, so that Figure 7 the pollutants as shown are separated from the air purification filter screen 310, and under the action of the blower 200, they are quickly blown towards the outdoor communication port 121, avoiding polluting the indoor air. The temperature of the PTC module is controllable, the temperature is constant, and it is safe to use.

[0095] Optionally, the heating module 330 is an infrared radiation module. The infrared radiation module can quickly raise the temperature of the air purification filter screen 310 and enable the air purification filter screen 310 to be quickly regenerated.

[0096] Optionally, the heating module 330 can also be an ultraviolet lamp assembly, so as to effectively kill the bacteria attached to the air purification filter screen 310.

[0097] When the heating module 330 (PTC module, infrared radiation module, ultraviolet lamp assembly) with the heating function is adopted above, the passing air can be heated. When the air purification filter screen 310 is in a relatively clean state and the heating module 330 is turned on, although the air purification filter screen 310 is in the desorption state at this time, there will be no excessive pollutants entering the room, but the temperature of the fresh air flowing into the room can be increased. Especially when the air treatment device 1000 is used in winter and operates with the introduction of fresh air, the effect is particularly obvious.

[0098] Advantageously, the catalytic temperature of the heating module 330 is set between 70 and 80 °C to prevent local high temperature due to catalytic regeneration.

[0099] Optionally, the regeneration catalytic module 320 includes a carrier. The air purification filter screen 310 is arranged inside the carrier. The carrier is detachably arranged in the housing 1, which is convenient for assembly into the housing 100 and convenient for replacement. When the regeneration catalytic module 320 is made into a detachable part, it is convenient to replace the part damaged by heat.

[0100] Advantageously, the carrier is made of high-temperature resistant materials such as BMC (Bulk Molding Compound), heat-resistant ABS (Acrylonitrile Butadiene Styrene), heat-resistant PC (Polycarbonate), etc., effectively preventing the local overheating and deformation of the regeneration catalytic module 320. Of course, all components near the heating module 330 can be made of high-temperature resistant materials as needed, and no specific limitation is made here.

[0101] Optionally, the regeneration catalytic module 320 further includes a catalyst, such as a metal oxide catalyst, a multi-metal composite catalyst, or a noble metal catalyst, thereby greatly improving the catalytic performance of the regeneration catalytic module 320, and the above-mentioned particulate matter is convenient to be loaded on the air purification filter 310.

[0102] Next, the air conditioner 2000 according to the embodiments of the present invention will be described with reference to the accompanying drawings of the specification.

[0103] An air conditioner 2000 according to an embodiment of the present invention includes: the air treatment device 1000 of the foregoing embodiment.

[0104] In the air conditioner 2000 according to the embodiment of the present invention, when the foregoing air treatment device 1000 is in the adsorption state and is used for a long time in an indoor closed space, the indoor air can be directly purified, so that the indoor temperature is suitable and the air quality is high. The air treatment device 1000 can recover the purification function through desorption, thereby maintaining excellent purification performance for a long time and improving the user experience.

[0105] In some embodiments of the present invention, as Figure 8 shown, the air conditioner 2000 includes: a wall-mounted indoor unit 500, and the air treatment device 1000 is connected to a horizontal end of the wall-mounted indoor unit 500. Thereby, the air treatment device 1000 is integrated on the wall-mounted indoor unit 500, greatly improving the functions of the air conditioner 2000, and enabling the air conditioner 2000 to have an air purification function and a self-purification function of the air filtration adsorption desorption purification unit 300, improving the use performance of the air conditioner 2000.

[0106] In other embodiments of the present invention, as Figure 9 shown, the air conditioner 2000 includes: a floor-standing cabinet 600, and the air treatment device 1000 is connected to the top or bottom of the floor-standing cabinet 600. Making the functions of the floor-standing cabinet 600 more abundant and improving the use performance.

[0107] Optionally, in some specific examples, the operation state of the air conditioner 2000 can be controlled in cooperation with the electronic control module. For example, by reading the operation time Ti of the machine for purification, when Ti reaches the program-set T1, the air conditioner prompts to turn on the desorption mode after shutdown.

[0108] After the air conditioner 2000 stops operating, the switching damper 400 is opened to open the outdoor communication port 121 and switch to the sewage discharge mode, and the regeneration catalytic module 320 and the heating module 330 are turned on to perform regeneration catalysis on the air purification filter 310. After the particulate matter is catalytically desorbed, it is discharged outdoors through the outdoor communication port 121.

[0109] After the desorption mode is completed, the particulate matter accumulated on the air purification filter 310 is completely desorbed, and it returns to the original optimal adsorption state again, achieving the purpose of purification and regeneration.

[0110] After the desorption mode is completed, continue to exhaust air for a certain period of time to ensure that all the desorbed particulate matter is blown out to the outside of the outdoor communication port 121 and does not stay inside the housing 100.

[0111] The following describes the specific structures of the air treatment device 1000 and the air conditioner 2000 in the specific embodiments of the present invention with reference to the accompanying drawings of the specification.
