Description

Technical Field

[0001] This application relates to the field of air conditioning equipment technology, and in particular to a wall-mounted air conditioning indoor unit. Background Technology

[0002] An air conditioner, also known as an air conditioner, is a device that uses artificial means to regulate and control parameters such as temperature, humidity, and airflow of the air inside a building or structure.

[0003] Currently, more and more people are choosing to install air conditioners indoors to regulate the temperature of the indoor air. Wall-mounted air conditioners are one type of air conditioner. The indoor unit's fresh air module draws in fresh outdoor air through a fresh air impeller and exhausts stale indoor air to the outside through an exhaust impeller, thus replacing the indoor air with fresh air. Furthermore, the heat exchange core allows for heat exchange between the incoming fresh air and the outgoing indoor air, ensuring that the temperature of the incoming fresh air is closer to the indoor temperature. This eliminates the need to start the compressor to heat or cool the fresh air, and also prevents the fresh air from significantly affecting the indoor temperature.

[0004] In the existing technology, the fresh air module of the wall-mounted air conditioner can purify the indoor polluted air. However, when the indoor polluted air is circulated and purified, the purified indoor air is drawn into the exhaust fan impeller and discharged outdoors from the exhaust fan heat exchange outlet when it is blown into the room from the fresh air heat exchange outlet. This results in the purified air not being able to stay in the room for a long time and play its due role, thus leading to poor air purification effect. Utility Model Content

[0005] This application discloses a wall-mounted air conditioner indoor unit that ensures that the purified indoor air will not be discharged outdoors from the exhaust heat exchange outlet when it is blown into the room from the fresh air heat exchange outlet, thus ensuring the air purification effect.

[0006] To achieve the above objectives, some embodiments of this application provide a wall-mounted air conditioner indoor unit, comprising: a casing; a fresh air module disposed within the casing, the fresh air module comprising: a fresh air volute; an exhaust volute connected parallel to the fresh air volute along its axial direction; a first housing connected to the air inlet side of the fresh air volute, the first housing having a fresh air inlet cavity communicating with the air inlet of the fresh air volute, the first housing having a fresh air inlet and an indoor air inlet; a fresh air impeller disposed within the fresh air volute, the fresh air impeller being used to draw in fresh outdoor air; an exhaust impeller disposed within the exhaust volute, the shaft of the exhaust impeller and the shaft of the fresh air impeller both extending along the axial direction of the fresh air volute, the exhaust impeller being used to exhaust stale indoor air; and a drive motor connected to the fresh air impeller and the exhaust impeller respectively, to drive the fresh air impeller and the exhaust impeller to rotate. The heat exchange core housing is disposed at the air outlet of the fresh air volute. The heat exchange core housing has a heat exchange chamber, which is connected to the air outlet of the fresh air volute and the air outlet of the exhaust volute. The heat exchange core housing is provided with: an exhaust heat exchange outlet for connecting to the outdoor space to exhaust the stale air to the outside; a fresh air heat exchange outlet for connecting to the indoor space to exhaust the fresh air to the indoor space; a heat exchange core disposed in the heat exchange chamber to perform heat exchange between the stale air and the fresh air flowing through the heat exchange chamber; a purification component disposed in the fresh air inlet chamber to purify the stale air and the fresh air flowing through the fresh air inlet chamber; a fresh air valve movably disposed at the fresh air inlet to open or close the fresh air inlet; and an exhaust valve movably disposed at the exhaust heat exchange outlet to open or close the exhaust heat exchange outlet.

[0007] In related technologies, the exhaust heat exchange outlet of the heat exchange core shell is normally open. When the fresh air module operates in purification mode to purify the indoor stale air, the stale air enters the fresh air intake cavity from the indoor air inlet, is purified by the purification components, and then is discharged into the room from the fresh air heat exchange outlet under the drive of the fresh air impeller. Because the exhaust heat exchange outlet is normally open, and the exhaust impeller and the fresh air impeller rotate synchronously under the drive motor, that is, while the fresh air impeller is rotating, the exhaust impeller is also rotating. This causes the purified air to not stay indoors sufficiently after being discharged from the fresh air heat exchange outlet. Instead, it is sucked into the exhaust volute by the exhaust impeller and discharged outdoors from the exhaust heat exchange outlet, resulting in poor purification effect.

[0008] In this embodiment, when both outdoor and indoor temperatures are comfortable, and the user's primary need is to improve indoor air quality, the fresh air module operates in purification mode. In this mode, the fresh air valve closes the fresh air inlet, and the exhaust valve closes the exhaust heat exchange outlet. By circulating and purifying the indoor air through the indoor air inlet, indoor air quality is rapidly improved while maintaining a comfortable indoor temperature. When the fresh air module operates in purification mode, the drive motor rotates the fresh air impeller and the exhaust impeller. Stale air enters the fresh air intake chamber through the indoor air inlet and is purified by the purification components. The purified air is then exhausted into the room through the fresh air heat exchange outlet, driven by the fresh air impeller. At this time, because the exhaust valve closes the exhaust heat exchange outlet, the exhaust path from the exhaust inlet to the exhaust heat exchange outlet is cut off. This prevents purified air from being drawn into the exhaust path by the exhaust impeller after being exhausted from the fresh air heat exchange outlet into the room and then exhausted to the outside. This ensures that the purified air can remain in the room for a sufficient period of time, guaranteeing the purification effect. Furthermore, when the fresh air module purifies the stale air in the room, there is no need to introduce outdoor fresh air. The fresh air valve closes the fresh air outlet, preventing the fresh air impeller from simultaneously introducing both indoor stale air and outdoor fresh air, which would reduce the amount of stale air introduced. This ensures that all the power of the fresh air impeller is used to draw in stale air for purification, guaranteeing a sufficient amount of purified indoor stale air.

[0009] Furthermore, this embodiment controls the opening and closing of the fresh air inlet and the exhaust heat exchange outlet through fresh air valves and exhaust valves respectively, enabling the fresh air module to achieve fresh air mode, exhaust mode, and heat exchange mode. When the outdoor fresh air temperature is more comfortable and the user's demand is more inclined to improve the temperature, the fresh air module operates in fresh air mode. In this case, the fresh air inlet is open and the exhaust heat exchange outlet is closed, introducing a large amount of comfortable fresh air through the fresh air inlet. Since the exhaust heat exchange outlet is closed, the fresh air does not undergo heat exchange at the heat exchange core, thus allowing the fresh air to enter the room and quickly improve the indoor temperature while improving air quality. When both indoor and outdoor air quality are poor, and it is necessary to avoid introducing fresh air into the room, the fresh air module operates in exhaust mode. In this case, the fresh air inlet is closed and the exhaust heat exchange outlet is open, purifying the indoor air while expelling a large amount of poor-quality indoor air to improve indoor air quality. When the indoor air quality is poor and the temperature difference between the outdoor fresh air and the indoor temperature is large, and the user needs to introduce fresh air and expel the poor-quality indoor air, the fresh air module operates in heat exchange mode. At this time, both the fresh air inlet and the exhaust heat exchange outlet are open. Fresh air is introduced through the fresh air inlet and poor-quality indoor air is discharged through the exhaust heat exchange outlet. The fresh air and the stale indoor air exchange heat at the heat exchange core, reducing the temperature difference between the fresh air blown into the room and the indoor temperature.

[0010] In some embodiments of this application, the indoor air inlet and the fresh air inlet are arranged adjacent to each other, and the fresh air valve is movably disposed between the fresh air inlet and the indoor air inlet. The fresh air module further includes: a first driving component, which is used to drive the fresh air valve to move between the fresh air inlet and the indoor air inlet. When the fresh air valve is located at the indoor air inlet, the fresh air inlet is open.

[0011] Thus, since the indoor air inlet and the fresh air inlet are arranged adjacent to each other, when the first drive component drives the fresh air valve to switch between the fresh air inlet and the indoor air inlet, the indoor air inlet can be opened and the fresh air inlet can be closed, or the indoor air inlet can be closed and the fresh air inlet can be opened. This ensures that when a large amount of fresh air needs to be introduced into the room, the fresh air inlet is opened and all the power of the fresh air impeller is used to draw in fresh air, thus ensuring the amount of fresh air drawn in.

[0012] In some embodiments of this application, the fresh air module further includes: a guide rail extending along the arrangement direction of the fresh air inlet and the indoor air inlet; the first driving component includes: a first driving member; a gear rotatably connected to the first driving member; and a rack disposed on the fresh air valve, the fresh air valve slidingly engaging with the guide rail, and the gear meshing with the rack.

[0013] Thus, on the one hand, this gear and rack transmission method can convert the power of the first driving component into linear motion of the fresh air valve along the guide rail. The first driving component provides power to drive the gear to rotate, which in turn drives the rack to translate along the guide rail, allowing the fresh air valve to move precisely between the fresh air inlet and the indoor air inlet. On the other hand, the guide rail provides a stable track for the movement of the fresh air valve, avoiding deviation or shaking during movement, and improving the overall reliability of the fresh air module.

[0014] In some embodiments of this application, the fresh air module further includes: a second driving component, the second driving component being used to drive the exhaust valve to open or close the exhaust heat exchange outlet, the second driving component including: a second driving member; a second transmission member, the second transmission member being connected between the exhaust valve and the second driving member, the second driving member driving the second transmission member to rotate, thereby driving the exhaust valve to open or close.

[0015] Thus, the design of the second drive component enables precise control of the exhaust valve. Furthermore, the first drive component independently drives the fresh air valve, and the second drive component independently drives the exhaust valve, allowing for flexible control of their movement according to different operating modes. In addition, the independent operation of the fresh air valve and the exhaust valve by the first and second drive components prevents them from interfering with each other, ensuring their normal operation.

[0016] In some embodiments of this application, the heat exchange core outer shell further comprises: a fresh air heat exchange inlet connected to the outlet of the fresh air volute; an exhaust air heat exchange inlet connected to the outlet of the exhaust air volute; and the heat exchange core contains: a fresh air flow channel connected to the fresh air heat exchange inlet and the fresh air heat exchange outlet; and a stale air flow channel connected to the exhaust air heat exchange inlet and the exhaust air heat exchange outlet; and the fresh air flow channel and the stale air flow channel are capable of heat exchange.

[0017] Thus, the heat exchange core is internally constructed with fresh air and stale air channels. The two ends of the fresh air channel are connected to the fresh air heat exchange inlet and outlet, respectively, while the two ends of the stale air channel are connected to the exhaust heat exchange inlet and outlet, respectively. Heat exchange can occur between the two channels. The heat exchange core is placed within the heat exchange chamber of its outer shell. The fresh air and stale air channels are arranged adjacently or alternately within the heat exchange core to achieve heat transfer, but they remain independent to ensure that fresh and stale air do not mix. The thorough heat exchange between fresh and stale air within the heat exchange core improves the energy efficiency of the air conditioning system, reduces energy consumption, minimizes heat loss between indoor and outdoor air, and enhances indoor air comfort.

[0018] In some embodiments of this application, the heat exchange core housing includes: a first housing; a second housing, the second housing being fastened to the first housing along the axial direction of the fresh air volute, the exhaust heat exchange outlet, the fresh air heat exchange inlet, the fresh air heat exchange outlet and the exhaust heat exchange inlet being disposed on the second housing; and a third housing, the third housing being fastened to the side of the second housing away from the first housing along the axial direction of the fresh air volute, the first housing, the second housing and the third housing surrounding to form the heat exchange cavity; wherein, the first housing is integrally formed with the first housing, the second housing is integrally formed with the fresh air volute, and the third housing is integrally formed with the exhaust volute.

[0019] This means that the outer shell of the fresh air module is formed by integrally molding and fastening together the first outer shell with the first housing, the second outer shell with the fresh air volute, and the third outer shell with the exhaust volute. This integrates the heat exchange core with the fresh air module, improving installation efficiency and reducing installation and module costs.

[0020] In some embodiments of this application, the purification component includes a high-efficiency air filter.

[0021] Thus, high-efficiency air filters can effectively filter particulate matter in the air, such as dust, pollen, and PM2.5. When air passes through an HEPA filter, these tiny particles are trapped on the filter media surface, significantly improving indoor air quality and providing users with a cleaner and healthier breathing environment. Furthermore, HEPA filters pre-treat the air before it enters the heat exchanger. This prevents particulate matter from adhering to the surface of the heat exchanger, keeping it clean and preventing dust and other particulate matter from covering the surface and reducing its heat exchange efficiency.

[0022] In some embodiments of this application, the housing includes: a rear plate for connecting to a wall; a front plate disposed opposite to the rear plate; and a bottom plate located at the bottom of the housing. The heat exchange core housing further includes: a front wall of the heat exchange core housing disposed towards the front plate; and a bottom wall of the heat exchange core housing disposed towards the bottom plate. The fresh air heat exchange outlet includes: a front outlet disposed on the front wall of the heat exchange core housing; and a lower outlet disposed on the bottom wall of the heat exchange core housing.

[0023] Thus, the design of the front and bottom air outlets allows fresh air to flow into the indoor space from different directions, improving the uniformity of indoor air distribution and enhancing user comfort. Furthermore, when the unit is mounted on the indoor wall, the front and bottom sides are easily visible to users, providing excellent visibility and allowing them to directly observe the fresh air outlets, further improving the user experience.

[0024] In some embodiments of this application, the front wall of the heat exchange core housing is further provided with a heat exchange core disassembly port, the heat exchange core disassembly port being connected to the heat exchange cavity, and the heat exchange core being detachably installed in the heat exchange cavity through the heat exchange core disassembly port.

[0025] Thus, the heat exchanger core disassembly port is connected to the heat exchange chamber, providing a channel for the installation and disassembly of the heat exchanger core. The detachable design simplifies and facilitates the installation and disassembly of the heat exchanger core, reducing the difficulty and cost of installation and maintenance. Furthermore, the heat exchanger core disassembly port is located on the front wall of the heat exchanger core housing, allowing the heat exchanger core to be disassembled and installed along the front side of the housing. Compared to disassembly and installation on the side or top of the housing, the front side is typically used for air outlet and is usually unobstructed. This eliminates the need to reserve space specifically for heat exchanger core disassembly and installation when mounting the housing to a wall, making housing installation more convenient and ensuring that no obstructions affect the disassembly and installation of the heat exchanger core.

[0026] In some embodiments of this application, the heat exchange core housing further comprises: a rear wall of the heat exchange core housing, which faces the rear plate along the front-rear direction of the housing, and is inclined relative to the rear plate to form an accommodating space between the rear wall of the heat exchange core housing and the rear plate; the fresh air module further comprises: an exhaust pipe connector, which is connected to the exhaust heat exchange outlet and disposed within the accommodating space; and a fresh air pipe connector, which is connected to the fresh air inlet and disposed within the accommodating space.

[0027] In this way, the available space provides a reasonable and compact installation location for the fresh air duct connector and the exhaust air duct connector, making more efficient use of the space inside the wall-mounted air conditioner indoor unit. This avoids the need to reserve space specifically for the fresh air duct and exhaust air duct when connecting the casing to the wall, making the casing more compact with the wall and making it easier to install and arrange the fresh air duct and exhaust air duct. This reduces the overall volume and makes the product more compact and aesthetically pleasing. Attached Figure Description

[0053] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0054] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0055] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0057] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0058] The field of home appliance technology encompasses a wide range of product categories, including but not limited to refrigerators, washing machines, air conditioners, microwave ovens, dishwashers, and vacuum cleaners. The technological development trends for these products primarily focus on intelligentization, energy conservation and environmental protection, optimized user experience, and the application of new materials. Optimized user experience is achieved through design innovation and functional enhancement to meet consumers' demands for health, convenience, and personalization.

[0059] As an important branch of home appliances, wall-mounted air conditioner indoor units use a fresh air module to introduce fresh outdoor air into the room through a fresh air impeller and exhaust stale indoor air to the outside through an exhaust impeller, thus completing the replacement of indoor air with fresh air. Moreover, through a heat exchange core, heat can be exchanged between the fresh air entering the room and the indoor air about to be exhausted, so that the temperature of the fresh air entering the room is closer to the indoor temperature. There is no need to start the compressor to heat or cool the fresh air separately, and the fresh air can also avoid significantly affecting the indoor temperature.

[0060] In existing wall-mounted air conditioner indoor units, the fresh air impeller and exhaust impeller of the fresh air module are driven by the same motor. When the fresh air module purifies indoor air, the air that needs purification enters the fresh air casing through the indoor air inlet, is purified by the purification components, and is then exhausted into the room through the fresh air heat exchange outlet under the drive of the fresh air impeller. However, while the fresh air impeller is rotating, the exhaust impeller is rotating synchronously. The purified air that has just been exhausted into the room from the fresh air heat exchange outlet is then exhausted to the outside through the exhaust air heat exchange outlet under the action of the exhaust impeller. This results in the purified air not being able to stay indoors sufficiently and play its due role, thus significantly reducing the air purification effect.

[0061] Based on this, this application provides a wall-mounted air conditioner indoor unit that ensures that the purified indoor air, after being blown into the room from the fresh air heat exchange outlet, will not be discharged outdoors from the exhaust heat exchange outlet, thus ensuring the air purification effect.

[0062] The present technical solution will be further described below with reference to the embodiments and accompanying drawings.

[0063] Please see Figure 1 This application provides a wall-mounted air conditioner indoor unit 100, which includes a housing 1. The housing 1 houses various functional components of the wall-mounted air conditioner indoor unit 100, such as a fan and a heat exchanger. These components, in conjunction with the outdoor unit of the air conditioner, can improve the indoor air environment, including cooling, heating, and humidity control.

[0064] like Figure 2 As shown, the wall-mounted air conditioner indoor unit 100 also includes a fresh air module 2, which is installed inside the casing 1 and is used to introduce fresh air from the outside into the room.

[0065] See Figures 3 to 5 The fresh air module 2 includes a fresh air volute 21, and a fresh air impeller 24 is installed inside the fresh air volute 21. The fresh air impeller 24 is used to draw in fresh air from the outside.

[0066] The fresh air module 2 also includes an exhaust volute 22, which is connected side-by-side with the fresh air volute 21 along the axial direction of the fresh air volute 21. The exhaust volute 22 is provided with an exhaust air inlet 221, which is connected to the room. An exhaust impeller 25 is provided inside the exhaust volute 22, and the shaft of the exhaust impeller 25 and the shaft of the fresh air impeller 24 both extend along the axial direction of the fresh air volute 21. The exhaust impeller 25 is used to draw in the stale air in the room through the exhaust air inlet 221 and exhaust it to the outside.

[0067] The fresh air module 2 also includes a first housing 23, which is connected to the air inlet side of the fresh air volute 21. The first housing 23 is provided with a fresh air inlet cavity 23a, which is connected to the air inlet of the fresh air volute 21. The first housing 23 is provided with a fresh air inlet 231 and an indoor air inlet 232. Fresh air and indoor air can enter the fresh air inlet cavity 23a through the fresh air inlet 231 and the indoor air inlet 232, respectively.

[0068] The fresh air module 2 also includes a drive motor 26, which is connected to the fresh air impeller 24 and the exhaust impeller 25 respectively, so as to drive the fresh air impeller 24 and the exhaust impeller 25 to rotate synchronously.

[0069] The fresh air module 2 can draw fresh outdoor air into the room through the fresh air impeller 24 from the fresh air volute 21, and then exhaust the stale indoor air to the outside through the exhaust impeller 25, thereby changing the indoor air quality by exchanging fresh air and replacing it with fresh air.

[0070] During the process of fresh air module 2 exchanging indoor air, the airflow formed by the outdoor fresh air being introduced into the room is called fresh air, and the airflow formed by the indoor air being exhausted is called stale air.

[0071] Combination Figure 2 and Figure 12 The fresh air module 2 also includes a heat exchange core housing 27, which is located at the air outlet of the fresh air volute 21. The heat exchange core housing 27 has a heat exchange chamber 27a, which is connected to the air outlet of the fresh air volute 21 and the air outlet of the exhaust volute 22. The heat exchange core housing 27 is provided with an exhaust heat exchange outlet 271 for connecting to the outdoor space to exhaust stale air to the outside. The heat exchange core housing 27 is also provided with a fresh air heat exchange outlet 272 for connecting to the indoor space to exhaust fresh air to the indoor space.

[0072] The fresh air module 2 also includes a heat exchange core 28, which is disposed in the heat exchange chamber 27a to exchange heat between the stale air and the fresh air flowing through the heat exchange chamber 27a.

[0073] like Figure 6 and Figure 7 As shown, the fresh air module 2 also includes a purification component 29, which is disposed within the fresh air intake cavity 23a to purify the stale air and fresh air flowing through the fresh air intake cavity 23a. When indoor stale air enters the fresh air intake cavity 23a through the indoor air inlet 232, it can be purified by the purification component 29. When outdoor fresh air enters the fresh air intake cavity 23a through the fresh air inlet 231, it can be purified by the purification component 29.

[0074] See Figure 8 and Figure 9 The fresh air module 2 also includes a fresh air valve 31, which is movably disposed at the fresh air inlet 231 to open or close the fresh air inlet 231.

[0075] The fresh air module 2 also includes an exhaust valve 32, which is movably disposed at the exhaust heat exchange outlet 271 to open or close the exhaust heat exchange outlet 271.

[0076] in, Figure 7 The middle arrow indicates the direction of indoor air after it enters the fresh air intake cavity 23a from the indoor air inlet 232.

[0077] In related technologies, the exhaust heat exchange outlet 271 of the heat exchange core housing 27 is normally open. When the fresh air module 2 operates in purification mode to purify the indoor stale air, the stale air enters the fresh air inlet cavity 23a from the indoor air inlet 232, is purified by the purification component 29, and is then discharged into the room from the fresh air heat exchange outlet 272 under the drive of the fresh air impeller 24. Since the exhaust heat exchange outlet 271 is normally open, and the exhaust impeller 25 and the fresh air impeller 24 rotate synchronously under the drive of the drive motor 26, that is, while the fresh air impeller 24 is rotating, the exhaust impeller 25 is also rotating. This causes the purified air to not stay in the room sufficiently after being discharged from the fresh air heat exchange outlet 272. Instead, it is sucked into the exhaust volute 22 by the exhaust impeller 25 and discharged outdoors from the exhaust heat exchange outlet 271, resulting in poor purification effect.

[0078] In this embodiment, when both outdoor and indoor temperatures are comfortable, and the user's needs prioritize improving indoor air quality, the fresh air module 2 operates in purification mode. At this time, the fresh air valve 31 closes the fresh air inlet 231, and the exhaust valve 32 closes the exhaust heat exchange outlet 271. Through the indoor air inlet, the circulating purification of indoor air achieves rapid improvement in indoor air quality while maintaining a suitable indoor temperature. When the fresh air module 2 operates in purification mode, the drive motor 26 drives the fresh air impeller 24 and the exhaust impeller 25 to rotate. Stale air enters the fresh air inlet chamber 23a through the indoor air inlet 232 and is purified by the purification component 29. The purified air is then exhausted into the room from the fresh air heat exchange outlet 272, driven by the fresh air impeller 24. At this time, since the exhaust valve 32 closes the exhaust heat exchange outlet 271, the exhaust path from the exhaust inlet 221 to the exhaust heat exchange outlet 271 is cut off. This prevents the purified air from being drawn into the exhaust path by the exhaust impeller 25 and discharged to the outside through the exhaust heat exchange outlet 271 after being discharged into the room from the fresh air heat exchange outlet 272. This ensures that the purified air can stay in the room for a sufficient period of time after being discharged into the room, thus ensuring the purification effect.

[0079] Furthermore, when the fresh air module 2 purifies the indoor stale air, there is no need to introduce outdoor fresh air. At this time, the fresh air valve 31 closes the fresh air inlet 231, which also avoids the fresh air impeller 24 from simultaneously introducing indoor stale air and outdoor fresh air, thus preventing a reduction in the amount of stale air introduced. This ensures that all the power of the fresh air impeller 24 is used to draw in stale air for purification, thus ensuring the amount of purified indoor stale air.

[0080] In addition, by setting the fresh air valve 31 and the exhaust valve 32, the opening and closing of the fresh air inlet 231 and the exhaust heat exchange outlet 271 are controlled respectively, so that the fresh air module 2 can also realize fresh air mode, exhaust mode and heat exchange mode.

[0081] When the outdoor air temperature is more comfortable and the user's need is more focused on improving the temperature, the fresh air module 2 operates in fresh air mode. In this mode, the fresh air inlet 231 opens, and the exhaust heat exchange outlet 271 closes. A large amount of comfortable-temperature fresh air is introduced through the fresh air inlet 231. Because the exhaust heat exchange outlet 271 is closed, the fresh air does not undergo heat exchange at the heat exchange core 28. This allows the fresh air to enter the room and quickly improve indoor temperature while simultaneously improving air quality. For example, if the outdoor temperature is warmer and the indoor temperature is lower, the fresh air module 2 operates in fresh air mode to introduce warmer outdoor fresh air. Since the fresh air does not undergo heat exchange when passing through the heat exchange core 28, the warm fresh air is blown into the room, making the indoor temperature more comfortable.

[0082] When both indoor and outdoor air quality are poor, and it is necessary to avoid introducing fresh air into the room, the fresh air module 2 operates in exhaust mode. At this time, the fresh air inlet 231 is closed and the exhaust heat exchange outlet 271 is open. While purifying the indoor air, a large amount of poor-quality indoor air is discharged to improve the indoor air quality.

[0083] When indoor air quality is poor and the temperature difference between the outdoor fresh air and the indoor temperature is significant, requiring the user to introduce fresh air and expel the poor-quality indoor air, the fresh air module 2 operates in heat exchange mode. In this mode, both the fresh air inlet 231 and the exhaust heat exchange outlet 271 are open. Fresh air is introduced through the fresh air inlet 231, and poor-quality indoor air is expelled through the exhaust heat exchange outlet 271. The fresh air and the stale indoor air exchange heat at the heat exchange core 28, reducing the temperature difference between the fresh air and the indoor temperature. For example, if the outdoor temperature is very low and the indoor temperature is high, the fresh air introduced into the room exchanges heat with the indoor air at the heat exchange core 28, making the temperature of the introduced fresh air closer to the indoor temperature. This prevents a large temperature difference between the fresh air and the indoor temperature from causing a drop in indoor temperature, ensuring the user experiences comfortable fresh air.

[0084] In some embodiments, combined with Figures 9 to 11 The indoor air inlet 232 and the fresh air inlet 231 are arranged adjacent to each other, and the fresh air valve 31 is movably arranged between the fresh air inlet 231 and the indoor air inlet 232.

[0085] The fresh air module 2 also includes a first drive component 4, which is used to drive the fresh air valve 31 to move between the fresh air inlet 231 and the indoor air inlet 232. When the fresh air valve 31 is located at the indoor air inlet 232, the fresh air inlet 231 is opened.

[0086] If the indoor air inlet 232 and the fresh air inlet 231 are set separately, it means that the fresh air valve 31 can only open and close the fresh air inlet 231, while the indoor air inlet 232 is always open. If a large amount of fresh air needs to be introduced into the room at this time, the fresh air inlet 231 and the indoor air inlet 232 will open at the same time, which will cause part of the power of the fresh air impeller 24 to be used to draw in indoor air, resulting in insufficient intake of fresh air.

[0087] In this embodiment, since the indoor air inlet 232 and the fresh air inlet 231 are arranged adjacent to each other, when the first drive component 4 drives the fresh air valve 31 to switch between the fresh air inlet 231 and the indoor air inlet 232, the indoor air inlet 232 can be opened and the fresh air inlet 231 can be closed, or the indoor air inlet 232 can be closed and the fresh air inlet 231 can be opened. This ensures that when a large amount of fresh air needs to be introduced into the room, the fresh air module 2 operates in fresh air mode, the fresh air inlet 231 is open, the indoor air inlet 232 is closed, the exhaust heat exchange outlet 271 is closed, and all the power of the fresh air impeller 24 is used to draw in fresh air, ensuring the amount of fresh air drawn in.

[0088] In some embodiments, such as Figure 9 and Figure 11 As shown, the fresh air module 2 also includes a guide rail 5, which extends along the arrangement direction of the fresh air inlet 231 and the indoor air inlet 232.

[0089] The first drive assembly 4 includes a first drive member 41, a gear 42 and a rack 43. The gear 42 is rotatably connected to the first drive member 41, and the rack 43 is disposed on the fresh air valve 31. The fresh air valve 31 is slidably engaged with the guide rail 5, and the gear 42 meshes with the rack 43.

[0090] On the one hand, this gear and rack transmission method can convert the power of the first driving component 41 into linear motion of the fresh air valve 31 along the guide rail 5. The first driving component 41 (such as a motor) provides power to drive the gear 42 to rotate, which in turn drives the rack 43 to translate along the guide rail 5, allowing the fresh air valve 31 to move precisely between the fresh air inlet 231 and the indoor air inlet 232. On the other hand, the guide rail 5 provides a stable track for the movement of the fresh air valve 31, avoiding deviation or shaking during movement, and improving the overall reliability of the fresh air module 2.

[0091] For example, when it is necessary to switch between fresh air mode and purification mode, simply control the first drive component to accurately move the fresh air valve to the designated position, ensuring that the opening and closing status of the fresh air inlet or indoor air inlet meets the requirements, effectively improving the reliability and accuracy of fresh air module mode switching.

[0092] It should be noted that in fresh air mode, the fresh air inlet 231 is open, the indoor air inlet 232 is closed, and the drive motor 26 drives the fresh air impeller 24 to rotate, drawing in fresh air which is then exhausted into the room through the fresh air heat exchange outlet 272. In purification mode, the fresh air inlet 231 is closed, the indoor air inlet 232 is open, and the drive motor 26 drives the fresh air impeller 24 to rotate, drawing in stale air from the room, purifying it through the purification component 29, and then exhausting it into the room through the fresh air heat exchange outlet 272.

[0093] It should be noted that in the fresh air mode, the exhaust heat exchange outlet 271 can be closed or open. When the exhaust heat exchange outlet 271 is open, the fresh air module 2 can not only introduce fresh air, but also exhaust the indoor stale air to the outside through the exhaust impeller 25. At the same time, heat exchange can be carried out when the stale air and fresh air pass through the heat exchange core 28, reducing the temperature difference between the fresh air blown into the room and the room, and improving the comfort when the fresh air is blown out.

[0094] In some embodiments, see Figures 9 to 11 The fresh air module 2 also includes a second drive component 6, which is used to drive the exhaust valve 32 to open or close the exhaust heat exchange outlet 271.

[0095] The second drive assembly 6 includes a second drive member 61 and a second transmission member 62. The second transmission member 62 is connected between the exhaust valve 32 and the second drive member 61. The second drive member 61 drives the second transmission member 62 to rotate, thereby causing the exhaust valve 32 to open or close.

[0096] The design of the second drive component 6 enables precise control of the exhaust valve 32. For example, when exhaust needs to be stopped, controlling the second drive component 61 to close the exhaust valve 32 can effectively prevent outdoor air from flowing back into the room and ensure indoor air quality; when exhaust is needed, it can quickly and accurately open the exhaust valve 32 to promptly expel stale indoor air and ensure the normal operation of the exhaust function.

[0097] Furthermore, the first drive component 4 independently drives the fresh air valve 31, and the second drive component 6 independently drives the exhaust valve 32, enabling flexible control of the movement of the fresh air valve 31 and the exhaust valve 32 according to different operating modes. For example, in fresh air mode, the exhaust valve 32 can be opened appropriately as needed to maintain indoor and outdoor air pressure balance and avoid excessive indoor pressure due to a large influx of fresh air, which would affect the fresh air input effect; in indoor circulation mode, the exhaust valve 32 is closed to ensure that indoor air circulates and is purified within the system, fully utilizing the function of the purification component 29 to meet the air conditioning needs under different operating conditions.

[0098] In addition, the first drive component 4 independently drives the fresh air valve 31, and the second drive component 6 independently drives the exhaust valve 32, which can prevent the fresh air valve 31 and the exhaust valve 32 from affecting each other and ensure their normal operation.

[0099] It should be noted that the second driving component 61 can be a motor, and the second transmission component 62 can be a gear and rack. The gear is connected to the motor, and the rack is mounted on the exhaust valve 32, with the gear meshing with the rack. The motor drives the gear to rotate, the gear drives the rack to move, and the exhaust valve 32 moves synchronously with the rack to open or close the exhaust heat exchange outlet 271.

[0100] In some embodiments, combined with Figure 12 and Figure 13 The heat exchange core housing 27 also has a fresh air heat exchange inlet 273 and an exhaust heat exchange inlet 274. The fresh air heat exchange inlet 273 is connected to the air outlet of the fresh air volute 21, and the exhaust heat exchange inlet 274 is connected to the air outlet of the exhaust volute 22.

[0101] A fresh air flow channel 281 is formed inside the heat exchange core 28, and the fresh air flow channel 281 is connected to the fresh air heat exchange inlet 273 and the fresh air heat exchange outlet 272 respectively.

[0102] The heat exchange core 28 also forms a turbid air flow channel 282, which is connected to the exhaust heat exchange inlet 274 and the exhaust heat exchange outlet 271 respectively.

[0103] Heat exchange is possible between the fresh air flow channel 281 and the turbid air flow channel 282.

[0104] Specifically, the heat exchange core 28 internally comprises a fresh air flow channel 281 and a stale air flow channel 282. The two ends of the fresh air flow channel 281 are connected to the fresh air heat exchange inlet 273 and the fresh air heat exchange outlet 272, respectively. The two ends of the stale air flow channel 282 are connected to the exhaust air heat exchange inlet 274 and the exhaust air heat exchange outlet 271, respectively. Heat exchange can occur between the two channels. The heat exchange core 28 is placed within the heat exchange chamber 27a of the heat exchange core outer shell 27. The fresh air flow channel 281 and the stale air flow channel 282 are arranged adjacently or alternately within the heat exchange core 28 to achieve heat transfer. However, the fresh air flow channel 281 and the stale air flow channel 282 are independent of each other, ensuring that the fresh air and stale air do not mix. The fresh air and stale air undergo sufficient heat exchange within the heat exchange core 28, improving the energy efficiency of the air conditioning system, reducing energy consumption, minimizing heat loss between indoor and outdoor air, and enhancing indoor air comfort.

[0105] In some embodiments, see Figure 2 and Figure 5 The heat exchange core housing 27 includes a first housing 275, a second housing 276, and a third housing 277. The second housing 276 is fastened to the first housing 275 along the axial direction of the fresh air volute 21. An exhaust heat exchange outlet 271, a fresh air heat exchange inlet 273, a fresh air heat exchange outlet 272, and an exhaust heat exchange inlet 274 are located on the second housing 276. The third housing 277 is fastened to the side of the second housing 276 away from the first housing 275 along the axial direction of the fresh air volute 21. The first housing 275, the second housing 276, and the third housing 277 form a heat exchange cavity 27a. The first housing 275 is integrally formed with the first housing 23, the second housing 276 is integrally formed with the fresh air volute 21, and the third housing 277 is integrally formed with the exhaust volute 22.

[0106] This means that the outer shell of the fresh air module 2 is formed by integrally molding and fastening together the first outer shell 275 and the first housing 23, the second outer shell 276 and the fresh air volute 21, and the third outer shell 277 and the exhaust volute 22. This integrates the heat exchange core 28 with the fresh air module 2, improving installation efficiency and reducing installation costs.

[0107] In some embodiments, the purification component 29 includes a high-efficiency air filter, also known as a HEPA filter.

[0108] High-efficiency particulate air (HEPA) filters effectively remove particulate matter from the air, such as dust, pollen, and PM2.5. When air passes through an HEPA filter, these tiny particles are trapped on the filter media surface. For example, for fine particles like PM2.5, HEPA filters utilize multiple mechanisms such as electrostatic adsorption and sieving to achieve a removal rate of over 95%, significantly improving indoor air quality and providing users with a cleaner and healthier breathing environment. Furthermore, before the air enters the heat exchange core 28, the HEPA filter pre-treats the air. This prevents particulate matter from adhering to the surface of the heat exchange core 28, keeping it clean and preventing dust and other particulate matter from covering its surface and reducing its heat exchange efficiency.

[0109] It should be noted that high-efficiency air filters, while filtering particulate matter, can also be used in conjunction with materials that adsorb odors and harmful gases (such as activated carbon). This can remove odors from the air, such as kitchen fumes and pet odors, as well as some volatile organic compounds, such as formaldehyde and benzene emitted from building materials, further improving indoor air quality and creating a more comfortable indoor environment.

[0110] It is understood that in this embodiment, the purification component 29 can be a high-efficiency air filter, an activated carbon filter, a negative ion generator, or an electrostatic precipitator, and this embodiment does not specifically limit it.

[0111] For example, when the purification component 29 is an electrostatic precipitator, the electrostatic precipitator ionizes airborne particles, charging them, and then uses an electrostatic field to attract the charged particles onto the collection plate. It can effectively remove dust, smoke, and other particulate matter from the air, with particularly good removal efficiency for fine particles. Its advantages include no need to replace the filter; only periodic cleaning of the collection plate is required, making it suitable for use in environments with high concentrations of airborne particulate matter.

[0112] When the purification component 29 is a negative ion generator, it can release a large number of negative ions. These negative ions can combine with positive ions in the air, causing particulate matter (such as dust and pollen) to clump together into larger particles, making them easier for other filtration devices to capture or for them to settle naturally. At the same time, negative ions help improve the air environment, making the air feel fresher and potentially helping to alleviate some respiratory symptoms.

[0113] In some embodiments, such as Figure 1 As shown, the housing 1 includes a rear plate 11, which is used to connect to the wall. In this embodiment, the housing 1 is mounted on the wall by fasteners.

[0114] The housing 1 also includes a front panel 12, which is disposed opposite to the rear panel 11.

[0115] The housing 1 also includes a base plate 13, which is located at the bottom of the housing 1.

[0116] Combination Figure 1 and Figure 4 The heat exchange core housing 27 also has a heat exchange core housing front wall 278, which is disposed toward the front panel 12.

[0117] The heat exchange core housing 27 also has a heat exchange core housing bottom wall 279, which is disposed toward the base plate 13.

[0118] The fresh air heat exchange outlet 272 includes a front outlet 2721 and a lower outlet 2722. The front outlet 2721 is located on the front wall 278 of the heat exchange core housing, and the lower outlet 2722 is located on the bottom wall 279 of the heat exchange core housing.

[0119] The design of the front air outlet 2721 and the bottom air outlet 2722 allows fresh air to flow into the indoor space from different directions, improving the uniformity of indoor air distribution and enhancing user comfort. Furthermore, when the unit 1 is mounted on the indoor wall, the front and bottom sides are easily visible to the user, thus providing excellent visibility for the front air outlet 2721 and the bottom air outlet 2722, allowing the user to directly observe the fresh air outlets and further enhancing the user experience.

[0120] In some embodiments, combined with Figure 2 and Figure 12 The front wall 278 of the heat exchange core housing is also provided with a heat exchange core disassembly port 2781, which is connected to the heat exchange chamber 27a. The heat exchange core 28 can be disassembled and installed in the heat exchange chamber 27a through the heat exchange core disassembly port 2781.

[0121] The heat exchange core removal port 2781 communicates with the heat exchange chamber 27a, providing a channel for the installation and removal of the heat exchange core 28. The detachable design simplifies and facilitates the installation and removal of the heat exchange core 28, reducing the difficulty and cost of installation and maintenance. Since the heat exchange core 28 is a key component of the heat exchange system, its cleaning and maintenance are crucial to the performance of the entire indoor air conditioning unit. This design improves the maintainability of the product, ensures the long-term stable operation of the indoor air conditioning unit, and reduces the risk of failure due to blockage or damage to the heat exchange core 28. The detachable design proposed in this embodiment allows maintenance personnel or users to easily remove the heat exchange core 28 from the heat exchange core housing 27 for cleaning, maintenance, or replacement, helping to maintain the performance of the heat exchange core 28 and extend its service life. Furthermore, in this embodiment, the heat exchange core disassembly port 2781 is located on the front wall 278 of the heat exchange core housing, allowing the heat exchange core 28 to be disassembled and assembled along the front side of the housing 1. Compared to disassembly and assembly on the side or top of the housing 1, the front side of the housing 1 is usually used for air outlet and is usually not obstructed. Therefore, when the housing 1 is installed on the wall, there is no need to reserve space specifically for the disassembly and assembly of the heat exchange core 28, making the installation of the housing 1 more convenient and without any obstructions affecting the disassembly and assembly of the heat exchange core 28.

[0122] It should be noted that a sealing structure, such as a sealing ring or sealing strip, can be designed at the heat exchange core disassembly port 2781 to ensure the sealing of the disassembly port after the heat exchange core 28 is installed, prevent air leakage, improve heat exchange efficiency, and at the same time prevent dust and contaminants from entering the heat exchange chamber 27a from the disassembly port.

[0123] It should be noted that a guide structure, such as a guide rail or guide groove, can also be provided inside the heat exchange core housing 27 to guide the heat exchange core 28 to be smoothly inserted into or pulled out of the heat exchange cavity 27a, ensuring accurate docking between the heat exchange core 28 and the heat exchange cavity 27a, and improving the convenience and reliability of installation.

[0124] It should be noted that a handle can also be provided on the surface of the heat exchange core 28 facing the heat exchange core disassembly port 2781, providing a convenient operating point for disassembling the heat exchange core 28. Users or maintenance personnel can easily pull the heat exchange core 28 out of the heat exchange core housing 27 using the handle, improving product maintainability and user experience. In addition, the handle can be designed to be foldable or concealed to reduce space occupation and improve the product's aesthetics; or the handle can be made of non-slip, heat-insulating materials to improve user comfort and safety, preventing inconvenience or injury caused by slipping or excessive temperature during disassembly.

[0125] In some embodiments, such as Figure 4 and Figure 6 As shown, the heat exchange core housing 27 also has a rear wall 280 along the front-rear direction of the housing 1. Figure 4 (From left to right or from right to left) The rear wall 280 of the heat exchange core housing faces the rear plate 11. The rear wall 280 of the heat exchange core housing is inclined relative to the rear plate 11 so that a receiving space M is formed between the rear wall 280 of the heat exchange core housing and the rear plate 11.

[0126] Combination Figure 4 and Figure 6 The fresh air module 2 also includes an exhaust pipe connector 7, which is connected to the exhaust heat exchange outlet 271 and is located within the accommodating space M.

[0127] The fresh air module 2 also includes a fresh air duct connector 8, which is connected to the fresh air inlet 231 and is located within the accommodating space M.

[0128] The exhaust duct connector 7 is connected to the exhaust heat exchange outlet 271, which connects the exhaust heat exchange outlet 271 to the exhaust duct, and then exhausts the stale air to the outside through the exhaust duct. The fresh air duct connector 8 is connected to the fresh air inlet 231, which connects the fresh air inlet 231 of the first housing 23 to the fresh air duct, and then introduces fresh air from the outside into the first housing 23 through the fresh air duct.

[0129] Due to the inclined arrangement of the rear wall 280 of the heat exchange core housing, a certain accommodating space is formed between the rear wall 280 of the heat exchange core housing and the rear plate 11 of the casing 1. The opening of this accommodating space M can face downwards from the casing 1, making it easier to install the exhaust duct and fresh air duct. The accommodating space M provides a reasonable and compact installation position for the fresh air duct connector 8 and the exhaust duct connector 7, making more efficient use of the internal space of the wall-mounted air conditioner indoor unit 100. This avoids the need to reserve space specifically for the fresh air duct and exhaust duct when connecting the casing 1 to the wall, allowing the casing 1 to be more compact with the wall and making it easier to install and arrange the fresh air duct and exhaust duct, reducing the overall volume and making the product more compact and aesthetically pleasing.

[0130] It should be noted that quick-connect devices can also be designed on the fresh air duct connector 8 and the exhaust air duct connector 7 to make the connection between the pipe and the connector more convenient and faster, without the need for complicated tools or cumbersome operating steps, thereby improving the efficiency of installation and maintenance.

[0131] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
