Description

Technical Field

[0001] This invention relates to the field of air treatment technology, and in particular to an air treatment device, an indoor air conditioning unit, and an air conditioner. Background Technology

[0002] As living standards improve, people are paying more and more attention to the comfort of their living environment, making air purification devices increasingly popular. Traditional air handling units mostly use consumable filters for adsorption, which have limited adsorption capacity and require regular replacement, resulting in high operating costs. Some air handling units with regenerative functions have emerged on the market, capable of desorbing pollutants through heating. However, the heating elements in these units are often poorly installed, affecting air intake efficiency and volume, and their sealing cannot be guaranteed, leading to safety concerns. Summary of the Invention

[0003] The main objective of this invention is to propose an air handling device that addresses the problems of traditional air handling devices having low adsorption capacity, requiring regular replacement, and incurring high operating costs; while air handling devices with regenerative functions suffer from reduced air intake efficiency and volume, and the inability to guarantee the sealing of the heating element, leading to low safety.

[0004] To achieve the above objectives, the present invention provides an air handling apparatus comprising:

[0005] The casing is equipped with air ducts;

[0006] A purification module, disposed in the air duct, is used to adsorb pollutants and desorb them under the action of hot air; and

[0007] A hot air generating component is disposed in the housing and is independent of the air duct. The hot air generating component is used to deliver hot air to the purification module.

[0008] Preferably, the housing is further provided with a fresh air intake duct, which is used to connect the outdoor environment with the air intake end of the duct. The hot air generating component is independent of the fresh air intake duct, but is connected to the fresh air intake duct.

[0009] Preferably, the air handling device further includes an exhaust switching door movably installed in the housing, the exhaust switching door being used to connect or disconnect the fresh air intake duct from the duct.

[0010] Preferably, the hot air generating assembly includes an outer cover, a blower, and a heating element. The blower and the heating element are both installed inside the outer cover. The outer cover is provided with a guide port. The blower is used to deliver air to the heating element, and the guide port is used to guide the hot air heated by the heating element to a preset position.

[0011] Preferably, the blower is positioned below the heating element, and the inner wall of the outer cover is provided with a guide surface, which is used to guide the air delivered by the blower to the heating element.

[0012] Preferably, the heating element is any one or more of a PTC heating element, a carbon tube heating element, and a pure ceramic heating element.

[0013] Preferably, the purification module includes a filter body and a regenerating catalyst or molecular sieve disposed on the filter body.

[0014] Preferably, the air handling device further includes a duct component disposed on the housing, the duct component having a main duct, the housing also having an air inlet and an air outlet, the air inlet, the duct, the main duct and the air outlet being sequentially connected, the air handling device further includes an air inlet switch door and an air outlet switch door, the air inlet switch door being openable and closable at the air inlet, the air outlet switch door being openable and closable at the air outlet, and the housing also having an exhaust duct for connecting the air outlet end of the main duct to the outdoor environment.

[0015] The present invention also proposes an indoor air conditioning unit, including the air handling device described above.

[0016] The present invention also proposes an air conditioner, including an outdoor unit and an indoor unit as described above, wherein the outdoor unit is connected to the indoor unit via a refrigerant pipe.

[0017] The technical solution of this invention utilizes a purification module and a hot air generating component. The purification module adsorbs pollutants to purify the air. When pollutants accumulate to a certain level, the hot air generating component delivers hot air to the purification module, which desorbs the pollutants under the action of the hot air, enabling the purification module to achieve regenerative adsorption. Compared to traditional air handling devices that use consumable filters for adsorption, the air handling device of this invention has a larger adsorption capacity and does not require regular replacement, effectively reducing operating costs. Furthermore, since the hot air generating component is installed independently outside the air duct, it avoids occupying the air inlet or internal space of the air duct, ensuring that air intake efficiency and volume are not affected. Simultaneously, because the hot air generating component is installed independently outside the air duct rather than inside it, a more complete sealing structure can be implemented for the heating element of the hot air generating component, improving the overall safety of the hot air generating component.

[0031] The present invention proposes an air handling device 100.

[0032] Please refer to Figure 1 and Figure 3 In one embodiment of the present invention, the air handling device 100 includes a housing 10, a purification module 30, and a hot air generating assembly 20. The housing 10 is provided with an air duct 11; the purification module 30 is disposed in the air duct 11, and the purification module 30 is used to adsorb pollutants and desorb the pollutants under the action of hot air; the hot air generating assembly 20 is disposed in the housing 10 and is independent of the air duct 11, and the hot air generating assembly 20 is used to supply hot air to the purification module 30.

[0033] Specifically, the housing 10 forms the main support structure of the air handling unit 100, and the purification module 30 and the hot air generating assembly 20 are both mounted on the housing 10. The purification module 30 is disposed within the air duct 11. When air carrying pollutants (such as benzene, aldehydes, nonanal, and other large molecular particles) passes through the air duct 11, the purification module 30 adsorbs the pollutants in the air, thereby purifying the air. The hot air generating assembly 20 is disposed independently outside the air duct 11, for example, as... Figure 3As shown, the hot air generating component 20 is independently located on the outer side of the air duct 11. The hot air generating component 20 is connected to the air duct 11 through a connecting channel, and the hot air generating component 20 does not occupy the air inlet or internal space of the air duct 11. The hot air generated by the hot air generating component 20 can enter the air duct 11 through the connecting channel and act on the purification module 30. The purification module 30 can desorb pollutants under the action of hot air, thereby enabling the purification module 30 to achieve regeneration adsorption function.

[0034] The technical solution of this invention, by setting up a purification module 30 and a hot air generating component 20, achieves air purification by adsorbing pollutants through the purification module 30. When pollutants accumulate to a certain level, hot air is supplied to the purification module 30 through the hot air generating component 20. Under the action of the hot air, the purification module 30 desorbs the pollutants, enabling the purification module 30 to achieve a regenerative adsorption function. Compared with traditional air handling devices that use consumable filters for adsorption, the air handling device 100 of this invention has a larger adsorption capacity and does not require regular replacement, effectively reducing operating costs. In addition, since the hot air generating component 20 is set independently outside the air duct 11, it avoids occupying the air inlet or internal space of the air duct, ensuring that the air intake efficiency and air volume are not affected. At the same time, since the hot air generating component 20 is set independently outside the air duct 11 rather than inside the air duct, a more complete sealing structure can be made for the heating element 23 of the hot air generating component 20, improving the overall safety of the hot air generating component 20.

[0035] Furthermore, such as Figure 6 As shown, the housing 10 is also provided with a fresh air intake duct 12, which is used to connect the outdoor environment with the air intake end of the duct 11. The hot air generating component 20 is independent of the fresh air intake duct 12, and the hot air generating component 20 is connected to the fresh air intake duct 12.

[0036] Specifically, please combine Figure 1 and Figure 6The housing 10 is equipped with a vertically extending fresh air duct 80, inside which a fresh air intake channel 12 is formed. One end of the fresh air duct 80 is connected to the outdoor atmosphere, and the side of the fresh air duct 80 has a connecting port for connecting to the air inlet end of the air duct 11. When the air handling unit 100 is in fresh air mode, outdoor fresh air enters the air duct 11 through the fresh air intake channel 12, and after being purified by the purification module 30, the clean fresh air is delivered indoors to provide clean fresh air for users. In addition, when users need to heat the air, the hot air generator 20 is turned on. The hot air generated by the hot air generator 20 mixes with the fresh air in the fresh air intake channel 12 and is then blown into the room together, thereby making the fresh air with a lower outdoor temperature warmer and more comfortable, effectively improving the user experience.

[0037] Furthermore, the air handling unit 100 also includes an exhaust switching door 40 movably installed on the housing 10. The exhaust switching door 40 is used to connect or disconnect the fresh air intake duct 12 from the duct 11. Specifically, the exhaust switching door 40 can be used to open or close the connection port on the fresh air duct 80. The exhaust switching door 40 has a first position and a second position. When it is necessary to activate the fresh air mode, the exhaust switching door 40 is switched to the first position (e.g., ...). Figure 6 As shown), at this time, the fresh air intake duct 12 is connected to the duct 11, allowing outdoor fresh air to enter the duct 11 through the fresh air intake duct 12 and then enter the room through the main duct 51. When it is necessary to turn off the fresh air mode, the exhaust switching door 40 can be switched to the second position to isolate the fresh air intake duct 12 from the duct 11, preventing fresh air from entering the room. Furthermore, when it is necessary for the air handling unit 100 to exhaust air to the outside, the exhaust switching door 40 can also be switched to the second position (e.g., Figure 4 As shown), so that the internal circulating air in the air handling unit 100 is discharged to the outside through a specific exhaust duct 13.

[0038] There are various ways to movably install the exhaust switching door 40 and the housing 10, including but not limited to rotational connection and sliding connection, as long as the exhaust switching door 40 can freely switch between the first position and the second position. Optionally, in this embodiment, the exhaust switching door 40 is rotatably installed on the housing 10 via a vertically extending rotating shaft. One end of the rotating shaft is connected to a driving component, which drives the rotating shaft to rotate, thereby allowing the exhaust switching door 40 to switch between the first position and the second position. This configuration has a simple overall structure and is easy to control. The driving component includes, but is not limited to, a motor and a rotary cylinder. Of course, in other embodiments, the driving component can also be a push-pull rod or a linkage mechanism to drive the exhaust switching door 40 to switch between the first position and the second position. Alternatively, in other embodiments, the exhaust switching door 40 and the housing 10 form a sliding connection structure through the cooperation of a slide rail and a slide groove, and a power component drives the switching door 40 to slide between the first position and the second position.

[0039] Further, please refer to Figure 2 The hot air generating assembly 20 includes an outer cover 21, a blower 22, and a heating element 23. Both the blower 22 and the heating element 23 are installed inside the outer cover 21. The outer cover 21 has a guide port 201. The blower 22 supplies air to the heating element 23, and the guide port 201 directs the hot air heated by the heating element 23 to a preset position. Specifically, an installation cavity is formed inside the outer cover 21, and both the blower 22 and the heating element 23 are disposed within this cavity. The outer cover 21 provides excellent protection for both the blower 22 and the heating element 23, and the heating element 23 is sealed within the outer cover 21, ensuring its safe operation. The outer cover 21 can be made of high-temperature resistant plastic, and the blower 22 can be a blower. The blower 22 blows cold air to the heating element 23. After the cold air comes into contact with the heating element 23, it quickly heats up to form hot air. The hot air is then transported to a preset position through the guide port 201. For example, the hot air can be transported to the fresh air intake duct 12 or the duct 11 through the guide port 201.

[0040] Furthermore, the blower 22 is positioned below the heating element 23, and the inner wall of the outer casing 21 is provided with a guide surface, which is used to guide the air delivered by the blower 22 to the heating element 23. Specifically, as shown... Figure 2As shown, the outer cover 21 extends vertically, and a first mounting cavity and a second mounting cavity are provided inside the outer cover 21 along the vertical direction. The sides of the first mounting cavity and the second mounting cavity are connected to form an air supply channel. The blower 22 is installed in the second mounting cavity, and the air outlet of the blower 22 faces the air supply channel. The heating element 23 is disposed in the first mounting cavity. The inner wall of the outer cover 21 is provided with a guide surface corresponding to the air supply channel, and the outer cover 21 is provided with a guide port 201 corresponding to the heating element 23. The overall structure is compact and occupies little space. The blower 22 transports air along the air supply channel. The air in the air supply channel is guided to the heating element 23 through the guide surface. After being heated by the heating element 23, it is output through the guide port 201. The guide surface and the guide port 201 can play a good guiding role for the air.

[0041] The heating element 23 can employ various heating methods, including but not limited to electric heating wire heating and infrared radiation heating, as long as they can provide a temperature rise for the gas flowing through the heating element 23. Optionally, the heating element 23 can be any one or more of a PTC heating element, a carbon tube heating element, and a pure ceramic heating element. Optionally, using a PTC heating element provides higher temperature controllability, ensuring constant temperature and safe operation.

[0042] Furthermore, the purification module 30 includes a filter body and a regeneration catalyst disposed on the filter body. When air flows through the purification module 30, pollutants in the air can be adsorbed and filtered through the filter body (such as a filter screen). When it is necessary to desorb pollutants, the hot air generating component 20 starts working, delivering hot air to the purification module 30. The regeneration catalyst on the filter body is heated and undergoes thermal catalysis, thereby enabling the pollutants adsorbed on the filter body in the previous stage to desorb. In another embodiment, the purification module 30 includes a filter body and a molecular sieve disposed on the filter body. For example, the molecular sieve can be loaded onto the filter body (such as a metal mesh or ceramic fiber mesh) to form a filter screen with a stable structure and excellent filtration performance.

[0043] Based on the above embodiments, please combine with Figure 1 , Figure 3 and Figure 5 Furthermore, the air handling device 100 also includes a duct component 50 disposed on the housing 10. The duct component 50 is provided with a main air duct 51. The housing 10 is also provided with an air inlet and an air outlet. The air inlet, the air duct 11, the main air duct 51 and the air outlet are connected in sequence. The air handling device 100 also includes an air inlet switch door 60 and an air outlet switch door 70. The air inlet switch door 60 is openable and closable at the air inlet. The air outlet switch door 70 is openable and closable at the air outlet. The housing 10 is also provided with an exhaust duct 13 for connecting the air outlet end of the main air duct 51 to the outdoor environment.

[0044] Specifically, the duct component 50 includes a duct housing and a fan housed within the duct housing. The fan can be a turbine fan. A main duct 51 is formed within the duct housing. The air inlet side of the main duct 51 is connected to and communicates with the air outlet side of the duct 11, and the air outlet side of the main duct 51 corresponds to the air outlet. Air enters the duct 11 through the air inlet, is purified by the purification module 30 of the duct 11, and the purified air is drawn into the main duct 51 by the fan, and finally delivered to the room from the air outlet. During use, the air inlet switch 60 and the air outlet switch 70 can be opened or closed according to different functional modes to achieve different functional modes.

[0045] The following combination Figures 3 to 6 Several functional modes of the air handling device 100 in this embodiment will be described in detail. For ease of understanding, the up, down, left, right, front, and rear directions of the air handling device 100 are marked in the figures, but this does not constitute a specific limitation on the air handling device 100. Figures 3 to 6 The bold arrows in the text indicate the direction of airflow.

[0046] like Figure 3 The diagram illustrates the airflow direction of the air handling unit 100 in purification mode. When the air handling unit 100 is in purification mode, the air inlet switch 60 opens the air inlet, the air outlet switch 70 opens the air outlet, and the exhaust switch 40 switches to the second position to isolate the fresh air intake duct 12 from the duct 11. Indoor air enters the duct 11 through the air inlet, and the purification module 30 adsorbs pollutants (such as benzene, aldehydes, nonanal, and other large molecular particles). The purified air enters the main air duct 51 and is blown into the room through the air outlet by the fan, thus achieving the air purification function.

[0047] like Figure 4 and Figure 5 The diagram illustrates the airflow direction of the air handling unit 100 in desorption mode. When the air handling unit 100 is in desorption mode, the air inlet switch 60 opens the air inlet, the air outlet switch 70 closes the air outlet, and the exhaust switch 40 switches to the second position to isolate the fresh air inlet duct 12 from the duct 11. The hot air generating component 20 starts working, and the internal circulating air carrying the high-temperature gas delivered by the hot air generating component 20 enters the purification module 30. After being thermally catalyzed, the regeneration catalyst in the purification module 30 begins to desorb the pollutants adsorbed on the filter body in the previous stage. The pollutants then enter the exhaust duct 13 through the main air duct 51 and are finally discharged outdoors through the exhaust duct 13, realizing the purification and regeneration function of the purification module 30. Furthermore, the pollutants are discharged outdoors, avoiding secondary pollution of indoor air. Figure 5As shown, optionally, the exhaust duct 13 is connected to the fresh air duct 80, and pollutants enter the fresh air duct 80 through the exhaust duct 13 and are then discharged to the outside. In this way, by setting up a single fresh air duct 80, both fresh air intake and exhaust functions can be achieved.

[0048] like Figure 6 The diagram illustrates the airflow direction of the air handling unit 100 in fresh air mode. When the air handling unit 100 is in fresh air mode, the air inlet switch 60 closes the air inlet, the air outlet switch 70 opens the air outlet, and the exhaust switch 40 switches to the first position to connect the fresh air inlet duct 12 with the air duct 11. Fresh outdoor air enters the air duct 11 through the fresh air inlet duct 12, is purified and adsorbed by the purification module 30, and then enters the main air duct 51. Under the action of the fan, it is delivered to the air outlet and blown into the room to provide users with clean and comfortable fresh air. In addition, in cold winters, the hot air generator 20 can be turned on. The hot air generated by the hot air generator 20 mixes with the fresh air in the fresh air inlet duct 12 before entering the air duct 11 and the main air duct 51 in sequence, and finally being delivered out of the air outlet, providing users with clean, warm, and comfortable purified air, thereby effectively avoiding the problem of a large temperature difference between the fresh air and the indoor temperature in winter.

[0049] This invention also proposes an air conditioner indoor unit, which includes a main body and an air handling unit 100 installed on the main body. The specific structure of the air handling unit 100 is as described in the above embodiments. Since this air conditioner indoor unit adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
