[0002] In related technologies, current air handling units in air conditioners can purify the airflow entering the air conditioner.

[0049] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein 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 accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0050] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0051] The following is for reference. Figures 1-22 An air handling unit 100 for an air conditioner 1000 and an air conditioner 1000 are described according to embodiments of the present invention.

[0052] like Figure 2 and Figure 3 As shown, the air handling component 100 of the air conditioner 1000 according to an embodiment of the present invention includes: an air duct assembly 10, a handling component 20, and a valve assembly 30.

[0053] See Figure 4 The air duct assembly 10 defines an air supply duct 10a. The air duct assembly 10 includes an indoor air inlet 10b and an outdoor air inlet 10c. Both the indoor air inlet 10b and the outdoor air inlet 10c are adapted to communicate with the air supply duct 10a. The air duct assembly 10 includes a fan wheel 11 disposed in the air supply duct 10a.

[0054] In other words, the air duct assembly 10 defines a first chamber structure (e.g., the housing of the air duct assembly 10 is a hollow structure), the first chamber structure defines an air supply duct 10a, and the first chamber structure has multiple openings, at least one opening is formed as an indoor air inlet 10b communicating with the indoor space, at least another opening is formed as an outdoor air inlet 10c communicating with the outdoor space, and at least another opening is formed as an outlet of the air supply duct 10a. The airflow generated by the impeller 11 disposed in the first chamber structure can be discharged from the outlet of the air supply duct 10a, and at least one of the indoor air inlet 10b and the outdoor air inlet 10c forms an inlet of the air supply duct 10a.

[0055] like Figure 10 and Figure 11As shown, the processing component 20 is located below the air duct component 10 and defines the processing air duct 20a. The processing component 20 includes a purification module 21 disposed in the processing air duct 20a. The inlet of the processing air duct 20a is connected to the outlet of the supply air duct 10a. The processing component 20 includes an indoor air outlet 20b and an outdoor air outlet 20c. Both the indoor air outlet 20b and the outdoor air outlet 20c are adapted to communicate with the processing air duct 20a. The indoor air outlet 20b is located downstream of the purification module 21.

[0056] In other words, the processing component 20 defines a second chamber structure (e.g., the housing of the processing component 20 is a hollow structure). The processing component 20 is located below the air duct component 10, so that the upper wall of the second chamber structure of the processing component 20 is at least partially open to form the inlet of the processing air duct 20a. The airflow discharged through the outlet of the air supply duct 10a can enter the second chamber structure of the processing component 20 through the inlet of the processing air duct 20a. The second chamber structure also has multiple openings, at least one of which is configured as an indoor air outlet 20b and is located downstream of the purification module 21 to ensure that the air processed by the purification module 21 can be discharged into the indoor space through the indoor air outlet 20b. At least another opening is configured as an outdoor exhaust outlet 20c. The relative position of the outdoor exhaust outlet 20c and the purification module 21 is not specifically defined.

[0057] It is understood that the air duct assembly 10 and the treatment assembly 20 can be integrated into a single unit or separate units. When both are integrated into a single unit, the integrated unit has a partition that divides the first chamber structure and the second chamber structure. The partition has an opening that forms the inlet of the treatment air duct 20a. At the same time, the indoor air inlet 10b, the indoor air outlet 20b, the outdoor air inlet 10c, and the outdoor air outlet 20c are all formed on the integrated unit. Multiple valve assemblies 30 are respectively set at the positions defined by the integrated unit for the indoor air inlet 10b, the indoor air outlet 20b, the outdoor air inlet 10c, and the outdoor air outlet 20c.

[0058] In other embodiments, the duct assembly 10 has a first housing, and the processing assembly 20 has a second housing. The first housing and the second housing are stacked vertically. The upper wall of the second housing and the lower wall of the first housing have openings that communicate with each other. The openings that communicate with each other define the inlet of the processing duct 20a. Meanwhile, the indoor air inlet 10b and the outdoor air inlet 10c are formed on the first housing, and the outdoor air outlet 20c and the indoor air outlet 20b are formed on the second housing. A portion of the valve assemblies 30 are respectively disposed on the first housing at the positions defining the indoor air inlet 10b and the outdoor air inlet 10c; another portion of the valve assemblies 30 are respectively disposed on the second housing at the positions defining the indoor air outlet 20b and the outdoor air outlet 20c.

[0059] like Figure 7 , Figure 8 and Figure 9 As shown, the valve assembly 30 is used to adjust the on / off state of the air supply duct 10a with the indoor air inlet 10b and the outdoor air inlet 10c respectively, and to handle the on / off state of the air duct 20a with the indoor air outlet 20b and the outdoor air exhaust outlet 20c respectively.

[0060] Specifically, the valve assembly 30 can be installed at the indoor air inlet 10b, the outdoor air inlet 10c, the indoor air outlet 20b, and the outdoor air outlet 20c. By controlling the opening and closing of the valve assembly 30, the airflow path within the air handling unit 100 can be controlled, thereby enabling switching between multiple purification modes.

[0061] In other words, the indoor air inlet 10b can be connected to the outdoor air outlet 20c to discharge indoor air to the outdoor space. During the process of indoor air being discharged, the exhaust airflow can be controlled to act on the purification module 21 to flush the purification module (by cooperating with other components, such as heating the airflow), so that at least some foreign objects (particulate matter) on the purification module 21 can be discharged under the action of the airflow, thereby achieving self-cleaning of the purification module 21. The indoor air inlet 10b is connected to the indoor air outlet 20b to achieve internal air circulation in the indoor space. The outdoor air inlet 10c is connected to the indoor air outlet 20b to allow fresh air to be supplied from the outdoor space to the indoor space.

[0062] It is understood that the valve assembly 30 of this embodiment is used to open and close the outdoor air inlet 10c, the indoor air inlet 10b, the indoor air outlet 20b, and the outdoor air outlet 20c. In some embodiments, the valve assembly 30 can be configured as a rotating door structure, with the door of the valve assembly 30 rotatably mounted on the opening via a pivot. The door can rotate relative to one side edge of the opening under the drive of a driving member to block or open the corresponding opening. In other embodiments, the valve assembly 30 can be constructed as a louver structure, with the door defined by multiple louvers that are spaced apart and rotatable. The valve assembly 30 is mounted on an opening. A connecting rod is mounted on one end of each louver, and a driving component is mounted on the other end. The driving component rotates one of the louvers, and the remaining louvers rotate synchronously under the influence of the connecting rod, thus opening or closing the corresponding opening. In some embodiments, the valve assembly 30 has a sliding door structure. The door is slidably mounted on the opening area. The driving component is connected to the door via a rack and pinion structure. The driving component drives the gear to move. The rack is integrally formed with the door and is used to push the door away from or towards the opening, thus opening or closing the corresponding opening.

[0063] In summary, the air handling unit 100 of the air conditioner 1000 according to the present invention provides valve assemblies 30 on the indoor air inlet 10b, the outdoor air inlet 10c, the indoor air outlet 20b, and the outdoor air outlet 20c, so that either the indoor air inlet 10b or the outdoor air inlet 10c can be connected to either the indoor air outlet 20b or the outdoor air outlet 20c. This allows the air handling unit 100 to switch between multiple purification modes, rather than being limited to the fresh air mode, thereby diversifying the purification modes of the air handling unit 100 to meet the user's needs. Furthermore, during the exhaust process, the exhaust airflow can be controlled to flush the purification module 21.

[0064] like Figure 11 and Figure 12 As shown, according to some embodiments of the present invention, the outdoor exhaust vent 20c includes at least one of a first exhaust vent 201c and a second exhaust vent 202c, wherein the first exhaust vent 201c is located upstream of the purification module 21 and the second exhaust vent 202c is located downstream of the purification module 21.

[0065] Specifically, the first exhaust vent 201c and the second exhaust vent 202c can be spaced apart in the vertical direction, so that the first exhaust vent 201c is located upstream of the purification module 21, and the airflow can be discharged through the first exhaust vent 201c without flowing through the purification module 21. The second exhaust vent 202c is located downstream of the purification module 21, that is, the airflow discharged from the second exhaust vent 202c needs to flow through the purification module 21.

[0066] Therefore, in the embodiment where the outdoor exhaust vent 20c only includes the first exhaust vent 201c, during the exhaust process, airflow can be prevented from flowing through the purification module 21. It is understood that the purification module 21 has components such as filters, or each purification module 21 is constructed as a filter of one type. By performing exhaust in this way, airflow can be prevented from flowing through the filters and other components during the exhaust process, thus avoiding impact on the filters and other components during the exhaust process. At the same time, exhaust resistance can be reduced, and the air in the indoor space can be quickly exhausted. This exhaust mode can be selected when there are odors in the room and sewage needs to be discharged. In the embodiment where the outdoor exhaust vent 20c only includes the second exhaust vent 202c, during the exhaust process, the airflow needs to flow through the purification module 21. During the exhaust process, the exhaust airflow can wash the filters and other components of the purification module 21, so that the particulate matter on the filters and other components can be discharged into the outdoor space. This can achieve self-cleaning of the air handling unit 100, and at the same time, it can extend the service life of the filters and other components, reduce the number of replacements of the filters and other components, and indirectly reduce the user's operating costs.

[0067] exist Figure 11 and Figure 12In the specific embodiment shown, the outdoor exhaust vent 20c includes a first exhaust vent 201c and a second exhaust vent 202c. The purification module 21 includes multiple layers of purification components stacked vertically. The purification module 21 divides the processing air duct 20a into an upper air duct 201a and a lower air duct 202a located on the upper and lower sides of the purification module 21. The top of the upper air duct 201a is open to communicate with the supply air duct 10a. The first exhaust vent 201c is set corresponding to the upper air duct 201a. The second exhaust vent 202c and the indoor air outlet 20b are both set corresponding to the lower air duct 202a.

[0068] Specifically, the vertically stacked multi-layer purification components may include: activated carbon filters, TVOC (Total Volatile Organic Compounds) filters, HEAP filters, ion generators, electrostatic dust collectors, ultraviolet sterilizers, formaldehyde removal filters, etc. The multi-layer purification components are all modularly designed and stacked vertically, so that users can reasonably select different purification components according to their usage needs. For example, after the interior decoration is completed and you move in, you can choose to install or replace multiple TVOC filters to effectively remove volatile substances from the indoor space. In areas with a lot of dust, when using an air conditioner, you can choose to install or replace multiple electrostatic dust collectors to effectively remove dust from the indoor space. When it is necessary to remove indoor odors, you can choose to install or replace multiple activated carbon filters to effectively eliminate odors. When it is necessary to disinfect and sterilize indoor air, you can choose to install or replace a UV sterilizer to effectively disinfect and sterilize. Alternatively, you can achieve disinfection and sterilization by setting up plasma filters or IFD (Intense Field Dielectric, which refers to a strong electric field filter that uses dielectric materials as carriers).

[0069] Among them, the first layer of the stacked multi-layer purification components contains a HEAP (multi-layer PP fiber stacked to form a dense and uniform microporous structure) filter, which initially and effectively purifies the air introduced into the indoor space and reduces the pollution to other purification components arranged downstream of the HEAP filter.

[0070] It is understood that, preferably, multiple purification components can be designed to be pull-out to fit the housing of the treatment component 20. When it is necessary to replace or select purification components, the corresponding purification component can be pulled out and installed, thereby improving the convenience of use.

[0071] Furthermore, it should be noted that in some embodiments, the purification module 21 is composed of multiple purification components, which are fixed by a frame. The frame and the housing of the processing component 20 are designed to be pull-out, so that the purification component that needs to be replaced can be taken out and replaced by pulling out the frame.

[0072] See Figure 11 and Figure 14 As shown, the housing of the processing component 20 is provided with a protrusion, and the frame or outer shell of the purification module 21 is provided with a groove that mates with the protrusion; or the housing of the processing component 20 is provided with a protrusion, and the frame or outer shell of the purification module 21 is provided with a protrusion that mates with the groove, so that the two form a pull-out fit, improving the convenience of replacement and optional installation. At the same time, a guide slope can be provided at the front end of the groove, and a limiting slot can be provided at the rear end of the groove to further improve the convenience of assembly.

[0073] It should be noted that in some embodiments, a purification module 21 is composed of multiple purification components, while in other embodiments, each purification module 21 is formed as a purification component. Thus, the corresponding purification function can be selected by directly replacing or assembling the purification module 21 or the individual purification component. The housing of multiple purification components or the frame structure of multiple purification modules 21 are consistent, which not only improves the convenience of stacking and installation, but also facilitates subsequent iteration and upgrades.

[0074] Furthermore, it should be noted that the purification module 21 divides the second chamber structure defined by the housing of the processing component 20 into two parts. The part located above the purification module 21 (i.e., the upper air duct 201a) is connected to the first exhaust port 201c, so that the air in the indoor space that does not need to be treated can be discharged to the outdoor space through the upper air duct 201a and the first exhaust port 201c, reducing exhaust resistance and improving exhaust efficiency. The part located below (i.e., the lower air duct 202a) is connected to the second exhaust port 202c, so that during the exhaust process, the airflow can be controlled to flow through the purification module 21, the lower air duct 202a, and the second exhaust port 202c in sequence before being discharged, thereby cleaning the purification module 21.

[0075] Furthermore, the housing of the processing component 20 has multiple protrusions or grooves in the vertical direction, so that the position of the purification module 21 in the height direction can be adjusted, thereby adjusting the volume of the upper air duct 201a and the lower air duct 202a, so that the volume of the upper air duct 201a and the lower air duct 202a can match the exhaust speed, avoiding the phenomenon of excessive exhaust noise during the exhaust process due to the lower thickness of the upper air duct 201a or the lower air duct 202a and the faster exhaust speed, and further improving the user experience of the air conditioner 1000.

[0076] like Figure 13As shown, according to some embodiments of the present invention, the indoor air outlet 20b includes a first air outlet 201b and a second air outlet 202b. The processing component 20 further includes a humidification module 22, which includes a wet membrane 221 disposed in the processing air duct 20a. The wet membrane 221 is located downstream of the purification module 21. The first air outlet 201b is located downstream of the purification module 21, and the second air outlet 202b is located downstream of the wet membrane 221.

[0077] Specifically, see Figure 11 and Figure 12 As shown, the indoor air outlet 20b includes a second air outlet 202b located on the side of the housing of the processing component 20 and a first air outlet 201b located on the bottom wall of the housing of the processing component 20. Both the first air outlet 201b and the second air outlet 202b are connected to the processing air duct 20a. The airflow processed by the purification module 21 can be directly discharged into the indoor space through the first air outlet 201b, or it can be further processed through the second air outlet 202b before being discharged into the indoor space.

[0078] It should be noted that the wet membrane 221 of the humidification module 22 is located upstream of the second air outlet 202b. When the air discharged into the indoor space is humidified by the humidification module 22, the airflow from the processing air duct 20a first flows through the wet membrane 221 and is humidified during the flow through the wet membrane 221. Then, it is discharged into the indoor space through the second air outlet 202b to achieve the humidification of the discharged airflow.

[0079] By placing the humidification module 22 downstream of the purification module 21, the water vapor generated by the wet film 221 during the operation of the air handling unit 100 can be prevented from wetting the purification components inside the purification module 21, thereby further improving the working stability of the air handling unit 100 and extending the service life of the purification module 21. Furthermore, by placing the second air outlet 202b downstream of the humidification module 22 and on the side, the humidification effect can be improved, and the airflow after humidification can be prevented from directly acting on the ground, causing the ground to become wet and producing water mist, thereby further improving the user experience of the air handling unit 100 and the air conditioner 1000.

[0080] like Figure 13As shown, the humidification module 22 also includes a water tank 222 and a water reservoir 223. The first air outlet 201b is located at the bottom of the processing component 20. The wet membrane 221 and the water reservoir 223 are located on opposite sides of the processing component 20. The water tank 222 extends along the outer periphery of the first air outlet 201b to avoid the first air outlet 201b. Both ends of the water tank 222 extend to the bottom of the wet membrane 221 and the water reservoir 223, respectively. The purification module 21 is located above the first air outlet 201b, or above at least a portion of the first air outlet 201b and the humidification module 22. The second air outlet 202b is arranged opposite to the wet membrane 221.

[0081] In other words, from a top-down perspective, the projections of the wet membrane 221, water tank 222, and water reservoir 223 form a "U" shape. The hollow area of ​​the U-shape is used to avoid obstructing the first air outlet 201b, ensuring the air outlet efficiency of the first air outlet 201b and preventing the water tank 222 from blocking the first air outlet 201b. At the same time, the water reservoir 223 stores water for humidification. The water tank 222 is constructed as a water flow channel between the wet membrane 221 and the water reservoir 223. The water in the water reservoir 223 can be supplied to the wet membrane 221 through the water tank 222. A water pump can be installed in the water reservoir 223 or the water tank 222 to pump water into the wet membrane 221, improving the humidification effect of the humidification module 22. A water level alarm can also be installed in the water reservoir 223 to promptly remind the user to add water when the water level in the water reservoir 223 is too low, preventing the user from noticing when the water reservoir 223 is empty and further improving the user experience.

[0082] See Figure 13 As shown, the wet membrane 221, water tank 222, and water reservoir 223 are all detachably fixed to the housing of the treatment component 20. Guide rails can be provided on the bottom walls of the wet membrane 221, water tank 222, and water reservoir 223, and corresponding guide grooves are provided on the bottom walls of the housing of the treatment component 20 to cooperate with the guide rails. This makes the water tank 222, water reservoir 223, and wet membrane 221 all designed as pull-out structures, which facilitates water filling of the water tank 223, cleaning of the water tank 222, and replacement of the wet membrane 221. At the same time, multiple strip-shaped limiting parts can be provided on the frame used to fix the wet membrane 221 to improve the stability of the wet membrane 221, thereby improving the working stability of the humidification module 22.

[0083] Furthermore, multiple upward-extending limiting plates can be provided on the bottom wall of the housing of the processing component 20. The limiting plates define a pull-out space between themselves and the side plates of the housing of the processing component 20. The water tank 223 and the water trough 222 can be slidably arranged in the pull-out space. The limiting plates can limit the position of the wet membrane 221 and the water tank 223, preventing them from shaking and improving the stability of the fit between the wet membrane 221 and the water tank 223 and the housing of the processing component 20. A limiting plate opposite to the water trough 222 can also be provided on the edge of the first air outlet 201b. The limiting plate is directly opposite to the side wall of the water trough 222 and can limit the position of the water trough 222, preventing the water trough 222 from being pushed too deep and obstructing the first air outlet 201b when the humidification module 22 is installed on the housing of the processing component 20.

[0084] like Figure 2 As shown, the air handling unit 100 further includes: a housing 42, at least one of the left and right side walls of the housing 42 having a first vent 42a, at least one of the left and right side walls of the housing 42 having a second vent 42b, the first vent 42a being higher than the second vent 42b, a third vent 42c being on the bottom wall of the housing 42, the air duct assembly 10 and the handling assembly 20 being both disposed inside the housing 42, the indoor air inlet 10b being opposite to and connected to the first vent 42a, the second air outlet 202b being opposite to and connected to the second vent 42b, and the first air outlet 201b being opposite to and connected to the third vent 42c.

[0085] Specifically, the outer casing 42 includes a rear housing 421 and a front panel 422, which define an accommodating space. The processing component 20 and the air duct component 10 are both disposed within the accommodating space. The air duct component 10 and the processing component 20 are stacked and placed within the accommodating space. The front panel 422 is connected to the rear housing 421 in front of the rear housing 421 to seal the accommodating space.

[0086] Furthermore, a first vent 42a, a second vent 42b, and a third vent 42c are provided around the periphery of the outer casing 42. The height of the first vent 42a at least partially coincides with the height of the indoor air inlet 10b, so that the first vent 42a and the indoor air inlet 10b are connected, and the indoor air inlet 10b can obtain air from the indoor space through the first vent 42a. The height of the second vent 42b at least partially coincides with the height of the second air outlet 202b. The second air outlet 202b is used to discharge airflow into the room in humidification mode, and the airflow flowing out of the corresponding second air outlet 202b can pass through the second vent 42b to be discharged into the indoor space.

[0087] The height of the first vent 42a is higher than that of the second vent 42b, dividing the indoor space into upper and lower layers according to height. The first vent 42a allows the air handling component 20 of the present invention to obtain air from the upper area of ​​the indoor space, while the second vent 42b can discharge the air processed by the air handling component 100 from the lower area of ​​the indoor space, which can promote the circulation of air in the indoor space and improve the humidification effect in humidification mode.

[0088] Furthermore, the third vent 42c corresponds to the first air outlet 201b. The first air outlet 201b is located on the bottom wall of the housing of the processing component 20, and the third vent 42c is located on the bottom wall of the outer casing 42. The two are arranged opposite each other. The airflow from the first air outlet 201b can be directly discharged into the indoor space through the third vent 42c. The third vent 42c is set close to the ground. During the process of the air handling unit 100 purifying the indoor air, indoor air is also obtained from the middle and upper area through the first vent 42a and discharged through the third vent 42c set close to the ground. This can realize the circulation of indoor air and improve the purification effect of indoor air.

[0089] It should be noted that the rear housing 421 has a top plate, side plates, back plate, and bottom plate. The first ventilation opening 42a and the second ventilation opening 42b are both formed on the side plates, and the third ventilation opening 42c is formed on the bottom plate. The first ventilation opening 42a, the second ventilation opening 42b, and the third ventilation opening 42c can all be formed as a grille structure. The grille density of the first ventilation opening 42a is greater than that of the second ventilation opening 42b and the third ventilation opening 42c. The grille densities of the second ventilation opening 42b and the third ventilation opening 42c can be the same or different. The valve assembly 30 set on the indoor air inlet 10b is opposite to the first ventilation opening 42a. The valve assembly 30 set on the first air outlet 201b is opposite to the third ventilation opening 42c. The valve assembly 30 set on the second air outlet 202b is opposite to the second ventilation opening 42b.

[0090] like Figure 4 and Figure 5 As shown, according to some embodiments of the present invention, the air duct assembly 10 includes: a centrifugal volute 12 and an air inlet frame 13. The air inlet frame 13 is disposed on at least one of the two axial sides of the centrifugal volute 12. An indoor air inlet 10b and an outdoor air inlet 10c are formed on the air inlet frame 13. The impeller 11 is a centrifugal impeller and is disposed inside the centrifugal volute 12.

[0091] It is understood that at least one of the two side panels of the rear housing 421 is provided with a first ventilation opening 42a, and the air inlet frame 13 is provided corresponding to the first ventilation opening 42a. If the left side panel of the rear housing 421 has a first ventilation opening 42a, then the centrifugal volute 12 is provided with an air inlet frame 13 on the side near the left side panel of the rear housing 421. If the right side panel of the rear housing 421 has a first ventilation opening 42a, then the centrifugal volute 12 is provided with an air inlet frame 13 on the side near the right side panel of the rear housing 421. Preferably, the left and right side panels of the rear housing 421 are provided with first ventilation openings 42a. 2a. Correspondingly, air inlet frames 13 are provided on both axial sides of the centrifugal volute 12. The side of the air inlet frame 13 away from the centrifugal volute 12 defines an indoor air inlet 10b, and the rear side of the air inlet frame 13 (the side away from the front panel 422) defines an outdoor air inlet 10c. This allows the air handling unit 100 to draw air from the indoor space through the indoor air inlet 10b located on the side of the centrifugal volute 12 when handling the air in the indoor space, and to draw air from the outdoor space through the outdoor air inlet 10c located on the rear side when handling the air entering the indoor space from the outdoor space.

[0092] It is understandable that the air conditioner 1000 is fixed in the indoor space and needs to be connected to the outdoor space through the outgoing gas pipe. Therefore, the outdoor air inlet 10c is formed on the rear side of the air inlet frame 13, and the indoor air inlet 10b is formed on the left and right sides of the air inlet frame 13. This is to facilitate the arrangement of the air handling unit 100 for the gas pipe connected to the outdoor space and to improve the aesthetics of the air conditioner 1000.

[0093] like Figure 6 As shown, the air duct assembly 10 further includes a heating element 14, which is disposed within the air inlet frame 13 and located downstream of at least one of the indoor air inlet 10b and the outdoor air inlet 10c.

[0094] Specifically, the heating element 14 can be located downstream of the indoor air inlet 10b, or downstream of the outdoor air inlet 10c, or both downstream of the indoor air inlet 10b and the outdoor air inlet 10c can be equipped with the heating element 14.

[0095] Both the indoor air inlet 10b and the indoor air outlet 20b are equipped with valve assemblies 30. The heating element 14 can be correspondingly installed after the valve assembly 30 to heat the gas entering the indoor space through the indoor air inlet 10b or the gas entering the outdoor space through the outdoor air inlet 10c. This makes the temperature of the gas entering the treatment component 20 more reasonable, avoids the temperature being too low, improves the working stability of the air handling unit 100, and improves the gas treatment effect of the purification module 21.

[0096] It is understood that the purification module 21 includes multiple vertically stacked purification components. Among these components, there are those with internal catalysts to reduce activation energy and purify the air. The activation capacity of the catalyst is closely related to temperature. By setting the heating element 14, the temperature of the gas entering the air handling unit 100 can be ensured to be more reasonable, so as to ensure that the activation capacity of the catalyst remains stable. This ensures the gas treatment effect of the purification module 21. At the same time, after the TVOC filter undergoes thermal catalysis, that is, after the heating element 14 heats the airflow passing through the TVOC filter, the particulate matter on the TVOC filter can be desorbed, thereby cleaning the purification module 21.

[0097] like Figure 2 and Figure 18 As shown, the air handling unit 100 also includes: a housing assembly 40, which has a fresh air inlet 50a and an exhaust duct 50b inside the housing assembly 40; an outdoor exhaust outlet 20c connected to the exhaust duct 50b; and both the outdoor air inlet 10c and the exhaust duct 50b connected to the fresh air inlet 50a.

[0098] Specifically, the housing assembly 40 includes at least: an outer shell 42, the outer shell 42 including: a rear housing 421 and a front panel 422, wherein the inner wall of the rear housing 421 defines an exhaust duct 50b between the housing of the air duct assembly 10 (in some embodiments of the present invention, the housing of the air duct assembly 10 may be defined by the air inlet frame 13) and the housing of the processing assembly 20, an outdoor exhaust port 20c is formed on the back panel of the housing of the processing assembly 20 to communicate with the exhaust duct 50b, an outdoor air inlet 10c is formed on the rear side of the air inlet frame 13 and communicates with the exhaust duct 50b, and a fresh air inlet 50a is formed on the rear housing 421.

[0099] Therefore, the fresh air inlet 50a, the exhaust duct 50b, and the outdoor air inlet 10c are connected to define the fresh air path. During the process of introducing outdoor air into the indoor space, the outdoor air can enter the exhaust duct 50b through the fresh air inlet 50a and then enter the outdoor air inlet 10c through the exhaust duct 50b. The outdoor exhaust outlet 20c, the exhaust duct 50b, and the fresh air inlet 50a are connected to define the exhaust path. During the process of exhausting gas into the outdoor space, the gas discharged from the outdoor exhaust outlet 20c flows into the exhaust duct 50b and is discharged through the fresh air inlet 50a.

[0100] In this way, by setting up the exhaust duct 50b and the fresh air inlet 50a, the air handling unit 100 can have multiple purification modes, including at least: fresh air mode and exhaust mode, which improves the diversification of the purification modes of the air handling unit 100, meets the user's needs, and improves the user experience.

[0101] exist Figure 18In the specific embodiment shown, the exhaust duct includes a first sub-duct 501b and a second sub-duct 502b. The housing assembly 40 includes: a cover plate 41 connected to the duct assembly 10 and defining the first sub-duct 501b between the cover plate 41 and the duct assembly 10; a fresh air inlet 50a formed on the cover plate 41 and communicating with the first sub-duct 501b; and an outdoor air inlet 10c communicating with the first sub-duct 501b. The housing 42 covers the cover plate 41, the duct assembly 10, and the processing assembly 20 and defines the second sub-duct 502b between the housing 42 and the processing assembly 20. The outdoor exhaust inlet 20c communicates with the second sub-duct 502b, and the second sub-duct 502b communicates with the first sub-duct 501b. The housing 42 has an opening to avoid the fresh air inlet 50a.

[0102] Specifically, the housing assembly 40 includes a housing 42 and a cover plate 41. The housing 42 has a accommodating space for accommodating the air duct assembly 10 and the processing assembly 20. The cover plate 41 covers the air inlet frame 13 of the air duct assembly 10, and the side wall of the cover plate 41 defines a first sub-air duct 501b between the cover plate 41 and the air inlet frame 13, so that the first sub-air duct 501b communicates with the outdoor air inlet 10c on the air inlet frame 13. A fresh air inlet 50a is provided on the cover plate 41, so that the fresh air inlet... 50a, the first sub-air duct 501b and the indoor air inlet 10b define the fresh air path. The housing of the treatment component 20 and the rear housing 421 define the second sub-air duct 502b. The second sub-air duct 502b is connected to the first sub-air duct 501b, and the outdoor exhaust outlet 20c is set opposite to the second sub-air duct 502b. The fresh air inlet 50a, the first sub-air duct 501b, the second sub-air duct 502b and the outdoor exhaust outlet 20c define the exhaust path.

[0103] like Figure 3 As shown, the cover plate 41 is fixed to the air inlet frame 13 by fasteners. The cover plate 41 has a certain thickness and is constructed as a hollow structure (i.e., the first sub-air duct 501b). The rear upper part of the rear housing 421 is designed to conform to the shape of the cover plate 41, and a clearance opening is provided on the top plate of the rear cover plate 41 to avoid the fresh air inlet 50a. The cover plate 41 defines a portion of the fresh air inlet 50a that extends out of the clearance opening, and the portion extending out of the clearance opening is connected to the gas pipeline that introduces air from the outdoor space into the indoor space; or a connecting pipe extending downward is provided on the top plate of the rear cover plate 41, and the connecting pipe is connected to the fresh air inlet 50a on the cover plate 41, and the gas pipeline that introduces air from the outdoor space into the indoor space is connected to the connecting pipe, so that the structure of the housing assembly 40 is more compact and the space occupied by the air handling unit 100 is more reasonable.

[0104] Furthermore, it is understood that the centrifugal volute 12 is positioned between the two air inlet frames 13, and the cover plate 41 is fixedly connected to the air inlet frame 13. Correspondingly, a clearance part needs to be provided in the middle area of ​​the cover plate 41 to avoid the centrifugal volute 12, so as to avoid interference between the cover plate 41 and the centrifugal volute 12 during the assembly process and improve the ease of assembly.

[0105] like Figure 5 , Figure 6 and Figure 11 As shown, in some embodiments, the valve assembly 30 includes at least one of a first switch door 31, a second switch door 32, a third switch door (not shown in the figure), and a fourth switch door 33, wherein the first switch door 31 is located at the indoor air inlet 10b and adjusts the opening and closing of the indoor air inlet 10b; the second switch door 32 is located at the outdoor air inlet 10c and adjusts the opening and closing of the outdoor air inlet 10c; the third switch door is located at the outdoor air outlet 20c and adjusts the opening and closing of the outdoor air outlet 20c; and the fourth switch door 33 is located at the indoor air outlet 20b and adjusts the opening and closing of the indoor air outlet 20b.

[0106] Specifically, each of the two air inlet frames 13 located on both sides of the centrifugal volute 12 has an indoor air inlet 10b, and each of the two indoor air inlets 10b is provided with a first switch door 31. The first switch door 31 can be constructed as any one of a sliding door structure, a rotating door structure, or a louver structure. Each of the two air inlet frames 13 has an outdoor air inlet 10c on its rear side, and each of the two outdoor air inlets 10c is provided with a second switch door 32. The second switch door 32 can also be constructed as any one of a sliding door structure, a rotating door structure, or a louver structure. The housing of the processing component 20 The back panel is provided with a first air outlet 201c and a second air outlet 202c spaced apart. At least one of the first air outlet 201c and the second air outlet 202c can be provided with a third switch door. The third switch door is preferably constructed as a louvered structure. The side panel of the housing of the processing component 20 is provided with a second air outlet 202b. The fourth switch door 33 on the second air outlet 202b is preferably constructed as a sliding door structure. The bottom plate of the housing of the processing component 20 is provided with a first air outlet 201b. The fourth switch door 33 on the first air outlet 201b is preferably constructed as a louvered structure.

[0107] Therefore, the opening and closing of the indoor air inlet 10b can be controlled by the first switch door 31, the opening and closing of the outdoor air inlet 10c can be controlled by the second switch door 32, the opening and closing of the outdoor air outlet 20c can be controlled by the third switch door, and the opening and closing of the indoor air outlet 20b can be controlled by the fourth switch door 33. This allows for reasonable control of the working states of multiple valve components 30 according to different working modes of the air handling unit 100, thereby enabling the opening and closing of the indoor air inlet 10b, the outdoor air inlet 10c, the indoor air outlet 20b, and the outdoor air outlet 20c. This makes switching between multiple purification modes of the air handling unit 100 simpler and more convenient.

[0108] Furthermore, a fifth switch door can be installed on the fresh air inlet 50a. This fifth switch door is used to control the opening and closing of the fresh air inlet 50a, and is preferably constructed as a rotating door structure. In this way, when it is necessary to close or open the fresh air inlet 50a, this can be achieved by controlling the state of the fifth switch door, further improving operational convenience.

[0109] like Figure 1 As shown, an air conditioner 1000 according to a second aspect embodiment of the present invention includes: a temperature regulating component 200 and an air handling component 100, wherein the air handling component 100 and the temperature regulating component 200 are arranged vertically, and the air handling component 100 is an air handling component 100 for the air conditioner 1000.

[0110] Specifically, the air handling unit 100 and the temperature regulating unit 200 of the air conditioner 1000 are stacked vertically. The air handling unit 100 may be located above the temperature regulating unit 200, or the temperature regulating unit 200 may be located above the air handling unit 100. The temperature regulating unit 200 is used for cooling or heating, and the air handling unit 100 is used for purification operations (removal of volatiles, removal of dust, removal of odors, etc.) and humidification operations.

[0111] According to an embodiment of the present invention, the air conditioner 1000 adopts the air handling unit 100 of the above embodiment. The air handling unit 100 has multiple purification modes, and the user can select from multiple purification modes according to the usage needs, which can improve the user experience.

[0112] It should be noted that the specific type of the air conditioner 1000 according to the embodiments of the present invention is not limited. For example, it can be a cabinet air conditioner, a wall-mounted air conditioner, or an integrated air conditioner. When the air conditioner 1000 is constructed as a cabinet air conditioner or an integrated air conditioner and is placed on the ground, the first air outlet 201b and the second air outlet 202b are arranged on the two sides of the housing of the processing component 20, and the second air outlet 202b is directly opposite the wet film 221 of the humidification module 22.

[0113] Furthermore, the air conditioner 1000 is a vertically mounted air conditioner, and the air handling unit 100 is located below the temperature regulating unit 200.

[0114] In other words, when the air conditioner 1000 of this embodiment is constructed as a vertically mounted air conditioner, the structure of the air handling unit 100 is more compact, making the vertically mounted air conditioner occupy less space. This facilitates the assembly of the vertically mounted air conditioner on the cavity and effectively reduces the weight of the vertically mounted air conditioner, thereby improving the stability of the vertically mounted air conditioner.

[0115] The following reference Figures 15-22 This invention specifically describes the various purification modes of the air handling unit 100 of the air conditioner 1000 in an embodiment of the present invention.

[0116] Air handling unit 100 includes: housing assembly 40, handling component 20 disposed within housing assembly 40, duct assembly 10, and valve assembly 30. Duct assembly 10 has a supply air duct 10a, an indoor air inlet 10b, and an outdoor air inlet 10c. Handling component 20 has a handling air duct 20a, an indoor air outlet 20b, and an outdoor air outlet 20c. Housing assembly 40 defines an exhaust air duct 50b with respect to handling component 20 and duct assembly 10. The rear housing 421 of housing assembly 40 has a first vent 42a and a second vent 42. b. The third ventilation opening 42c and the exhaust duct 50b include: a first sub-duct 501b and a second sub-duct 502b. The processing duct 20a is divided by the purification module 21 into: an upper duct 201a and a lower duct 202a.

The outdoor exhaust outlet 20c includes: a first exhaust outlet 201c connected to the upper duct 201a and a second sub-duct 502b connected to the lower duct 202a.

[0117] The valve assembly 30 is disposed on the indoor air inlet 10b, the indoor air outlet 20b, the outdoor air outlet 20c, and the outdoor air inlet 10c, so that the air handling component 100 of the present invention has at least the following purification modes:

[0118] I. Fresh Air Mode:

The first switch door 31 and the third switch door are closed. The air in the outdoor space enters the first sub-air duct 501b through the fresh air inlet 50a, and enters the supply air duct 10a through the first sub-air duct 501b and the outdoor air inlet 10c. Under the action of the impeller 11, the air enters the upper air duct 201a through the inlet of the processing air duct 20a, flows through the purification module 21, and enters the lower air duct 202a. It is then discharged into the indoor space through the first air outlet 201b and the third ventilation outlet 42c connected to the lower air duct 202a, so as to achieve the purification of the air introduced from the outdoor space and the replenishment of fresh air.

[0120] II. Internal Circulation Mode:

The air in the indoor space enters the air supply duct 10a through the first vent 42a and the indoor air inlet 10b, and under the action of the impeller 11, it enters the upper air duct 201a through the inlet of the processing air duct 20a, flows through the purification module 21, enters the lower air duct 202a, and is discharged into the indoor space through the first air outlet 201b and the third vent 42c connected to the lower air duct 202a, so as to achieve the purification of the indoor air.

[0122] III. Humidification Mode:

The air in the indoor space enters the air supply duct 10a through the first vent 42a and the indoor air inlet 10b, and under the action of the impeller 11, it enters the upper air duct 201a through the inlet of the processing air duct 20a, flows through the purification module 21, enters the lower air duct 202a, and is discharged into the indoor space through the second air outlet 202b and the second vent 42b connected to the lower air duct 202a, so as to achieve the purification and humidification of the indoor air.

[0124] IV. First Exhaust Mode:

[0125] See Figure 17 and Figure 21 As shown, in the first exhaust mode, the first switch door 31 is open, the third switch door corresponding to the first exhaust vent 201c is closed, the third switch door corresponding to the second exhaust vent 202c is open, the fifth switch door is open, and the second switch door 32 and the fourth switch door 33 are closed. The air in the indoor space enters the supply air duct 10a through the first ventilation port 42a and the indoor air inlet 10b, and under the action of the impeller 11, it enters the upper air duct 201a through the inlet of the treatment air duct 20a, flows through the purification module 21, enters the lower air duct 202a, and enters the second sub-air duct 502b of the exhaust air duct 50b through the second exhaust vent 202c connected to the lower air duct 202a. From the second sub-air duct 502b, it enters the first sub-air duct 501b, and then is discharged to the outdoor space through the fresh air inlet 50a, so as to realize the exhaust of the indoor air to the outside. At the same time, the purification module 21 can be self-cleaned by the exhaust airflow.

[0126] V. Second Exhaust Mode:

[0127] See Figure 17 and Figure 22 As shown, in the second exhaust mode, the first switch door 31 is open, the third switch door corresponding to the first exhaust vent 201c is open, the third switch door corresponding to the second exhaust vent 202c is closed, the fifth switch door is open, and the second switch door 32 and the fourth switch door 33 are closed. The air in the indoor space enters the supply air duct 10a through the first ventilation opening 42a and the indoor air inlet 10b, and under the action of the impeller 11, it enters the upper air duct 201a through the inlet of the treatment air duct 20a, enters the first sub-air duct 501b through the upper air duct 201a, and then is discharged to the outdoor space through the fresh air inlet 50a, so as to realize the exhaust of the indoor space air to the outside.

[0128] In summary, the air handling component 100 of this embodiment can select from at least the above-mentioned multiple purification modes. While achieving the common fresh air mode of purifying outdoor air before introducing it into the indoor space, it can also directly achieve internal circulation purification of indoor air and humidification simultaneously to improve the user experience. More importantly, it has two exhaust modes. In the first exhaust mode, indoor air can flow through the purification module 21 and the first sub-duct 501b connected to the fresh air inlet 50a, allowing some of the adhering substances on the filters and other components of the purification module 21 to be desorbed and discharged outdoors (e.g., particulate matter desorbed from the TVOC filter after thermal catalysis). This achieves self-cleaning of the purification module 21 and allows airflow to be discharged outdoors, avoiding secondary pollution of the indoor space, extending the service life of the purification module 21, and reducing costs. In the second exhaust mode, the airflow does not need to flow through the purification module 21 during exhaust, reducing exhaust resistance and enabling rapid air removal from the indoor space.
