Description

Technical Field

[0001] The invention relates to household appliances, in particular to a wall-mounted air-conditioner indoor unit. Background Art

[0002] In order to save space, home appliances such as air conditioners are becoming increasingly miniaturized, but users have higher and higher requirements for their air supply performance, appearance and other aspects. The traditional wall-mounted air conditioner indoor unit has a single appearance, and the limitation of shape change has limited the improvement of air conditioner performance to a certain extent.

[0003] In the prior art, the wall-mounted air conditioner indoor unit usually guides the air supply from the air outlet by combining a swing blade and an air guide plate, wherein the air guide plate swings back and forth around its laterally extending rotating shaft driven by a motor, and the swing blade swings left and right around its rotating shaft, thereby adjusting the air supply direction of the air outlet in the up-down direction and left-right direction. In the prior art structure, the size of the air supply range of the air outlet depends on the air guide plate and the swing blade. However, due to the limitation of the casing structure, the swing amplitude of the air guide plate and the swing blade has a maximum limit value, so the expansion of the air supply range of the air outlet is also limited.

[0004] In addition, the indoor unit of the air conditioner achieves the purpose of cooling or heating through the heat exchange between the evaporator and the air. Generally speaking, the larger the area of ​​the evaporator, the higher the efficiency of the heat exchange. The traditional wall-mounted indoor unit of the air conditioner uses a cross-flow fan to drive the air flow, and the evaporator is half-wrapped on the outside of the cross-flow fan. It is generally believed in the prior art that the evaporator area of ​​this indoor unit using a cross-flow fan is not large enough and the heat exchange efficiency is not high. For this reason, in order to unilaterally pursue a larger evaporator area, some prior arts replace the cross-flow fan with an axial flow fan or a centrifugal fan. However, a single axial flow fan or centrifugal fan cannot meet the normal air supply volume requirements, and multiple axial flow fans or centrifugal fans need to be set up. In addition, the axial flow fan has strict requirements on the position of the air inlet. The air duct structure of the centrifugal fan is relatively complex and occupies space, resulting in the structure of this type of wall-mounted indoor unit of the air conditioner being very complex, relatively large in size, and having a large operating noise. Summary of the invention

[0005] An object of the present invention is to overcome at least one defect in the prior art and to provide a wall-mounted air conditioner indoor unit having a simple structure, capable of multi-mode dual-zone air supply and a wide air supply range.

[0006] Another object of the present invention is to improve heat exchange efficiency and induced air volume and reduce operating noise.

[0007] A further object of the present invention is to improve the appearance of a wall-mounted air conditioner indoor unit and increase its air supply volume.

[0008] In order to achieve the above object, the present invention provides a wall-mounted air conditioner indoor unit, comprising:

[0009] A housing, having an air inlet and an air outlet extending transversely along the housing, wherein two independent air guide plates are arranged side by side in the transverse direction at the air outlet, and each of the air guide plates is configured to be controlled to pivot around its own rotation axis parallel to the extension direction of the air outlet, so as to adjust the opening and closing state and / or the air outlet direction of the air outlet area corresponding to the air guide plate;

[0010] Two independent cross-flow fans are arranged side by side in the housing in a transverse direction, each of the cross-flow fans is configured to rotate around its own rotation axis in a controlled manner, and the rotation axes of the two cross-flow fans extend obliquely forward from the two transverse ends of the housing to the middle of the housing, so that the projections of the rotation axes of the two cross-flow fans in the horizontal plane form a V-shape that gradually tilts forward from the two transverse ends of the housing to the middle thereof; and

[0011] The evaporator is covered on the two cross-flow fans and includes a first heat exchange section, a second heat exchange section and a third heat exchange section which are sequentially connected from back to front, wherein the first heat exchange section is located at the rear side or the upper rear side of the two cross-flow fans, and the third heat exchange section is located at the front side of the two cross-flow fans, and the first heat exchange section and the third heat exchange section are both V-shaped heat exchange sections which gradually extend forward in an inclined manner from the lateral ends of the casing to the middle thereof, or curved heat exchange sections which gradually protrude forward and bend and extend.

[0012] Optionally, the wall-mounted air conditioner indoor unit further includes:

[0013] Two independent guide plate motors are disposed in the housing, and the rotation output shaft of each guide plate motor is connected to the rotation shaft of a corresponding one of the guide plates to drive the guide plate to pivot in a controlled manner; and

[0014] The two guide plate motors are configured to be controlled to rotate in one of three rotation modes, including synchronous rotation of the two guide plate motors, asynchronous rotation of the two guide plate motors, and any one of the guide plate motors rotates while the remaining one of the guide plate motors stops.

[0015] Optionally, the second heat exchange section is located above or above the crossflow fan, and

[0016] The second heat exchange section is a planar heat exchange section, or the second heat exchange section is a V-shaped heat exchange section extending from the two lateral ends of the casing to the middle thereof and gradually tilting toward the inner side of the cross-flow fan.

[0017] Optionally, the top edge of the first heat exchange section is adjacent to the rear edge of the second heat exchange section and has the same shape; and / or

[0018] The front side edge of the second heat exchange section is adjacent to the top edge of the third heat exchange section and has the same shape.

[0019] Optionally, the third heat exchange section includes two third heat exchange sub-sections extending gradually forward and tilted from the two lateral ends of the casing to the middle thereof, and the first heat exchange section includes two first heat exchange sub-sections extending gradually forward and tilted from the two lateral ends of the casing to the middle thereof; wherein

[0020] The inclination angles of the two first heat exchange subsections are respectively consistent with the inclination angles of the rotating shafts of the two cross-flow fans, and the inclination angles of the two third heat exchange subsections are respectively consistent with the inclination angles of the rotating shafts of the two cross-flow fans.

[0021] Optionally, the housing includes a front panel for forming a front portion thereof, and a cross section of the front panel cut along a horizontal section plane is in a V-shape that gradually tilts forward from both lateral ends of the housing toward the middle thereof.

[0022] Optionally, the front panel includes two vertically placed and symmetrically arranged plate bodies, each of which extends obliquely forward from its own first end located at the lateral end of the housing to its own second end located in the middle of the housing;

[0023] The second ends of the two plates are fixedly connected or the two plates are integrally formed; and

[0024] The adjacent part of the second ends of the two plates is located in a vertical bisecting plane extending along the front-to-back direction of the wall-mounted air conditioner indoor unit.

[0025] Optionally, the air inlet is formed at the top of the housing, and a front edge of the air inlet is adjacent to a top edge of the front panel.

[0026] Optionally, the air outlet is located at the front bottom of the housing; and

[0027] The wall-mounted air conditioner indoor unit also includes a guide plate, which is arranged at the bottom of the casing and below the air outlet, and forms a guide gap with the bottom of the casing to allow natural wind in the room that has not undergone heat exchange to flow from back to front through the guide gap, thereby mixing with the airflow after heat exchange flowing out of the air outlet and then being sent to the room.

[0028] Optionally, a longitudinal section of the guide plate cut along a vertical section plane perpendicular to the front-rear direction is in a V-shape that gradually slopes downward from the two lateral ends of the casing to the middle of the casing.

[0029] The present invention sets two independent crossflow fans and two independent air guide plates. The start / stop state, rotation speed and other parameters of each crossflow fan, as well as the swing angle, frequency, amplitude and other parameters of each air guide plate can be freely set by the user. The combination of the two realizes dual-zone air supply in multiple modes, meets the different needs of users in different areas, and improves the user experience. In addition, the rotating shafts of the two crossflow fans are specially designed to extend forward from the two lateral sides of the casing to the middle of the casing, respectively. As a result, the air outlet direction of each crossflow fan is toward the lateral outer side and front lower side of the casing, breaking through the limitation of the air supply angle of the crossflow fan in the conventional setting mode in the prior art, and expanding the air supply range of the indoor unit.

[0030] Furthermore, the present application breaks through the traditional design concept that the cross-flow fan must be replaced with other fan types in order to increase the evaporator area. On the basis of using the cross-flow fan as the driving air supply device, the evaporator structure is improved. The third heat exchange section at the front side of the cross-flow fan and the first heat exchange section at the rear side or the rear upper side of the cross-flow fan of the three-stage evaporator are specially designed to be a V-shaped heat exchange section that gradually extends forward from the lateral ends of the casing to the middle of the casing or a curved heat exchange section that gradually bulges forward and extends. Thus, on the basis of ensuring a simple structure, the length of the first heat exchange section and the third heat exchange section is increased at the same time, thereby increasing the effective heat exchange area of ​​the evaporator, thereby improving the heat exchange efficiency and the energy consumption level of the indoor unit. In addition, since the first heat exchange section is V-shaped, a roughly triangular or arched space can be formed between the first heat exchange section and the frame of the casing, increasing the size of the gap between the two, which is conducive to the rapid permeation of air through the evaporator, reducing the resistance of air flow in the casing, and reducing the operating noise of the wall-mounted air conditioner indoor unit. At the same time, the air supply volume is increased to a certain extent, thereby increasing the air supply volume of the indoor unit of the wall-mounted air conditioner.

[0031] Furthermore, the present application specially designs the front panel of the casing so that the cross section of the front panel cut along the horizontal section is in a V-shape that gradually tilts forward from the lateral ends of the casing to the middle of the casing, so that the front panel can match the layout of the two cross-flow fans and the shape of the third heat exchange section of the evaporator. In this way, not only the volume of the indoor unit of the wall-mounted air conditioner is reduced as much as possible to meet the development trend of miniaturization, but also the air supply volume is further increased, thereby greatly increasing the air supply volume of the indoor unit of the wall-mounted air conditioner. At the same time, the V-shaped front panel gives people a refreshing sense of technology and high-end feeling in appearance. It can be seen that the present invention can achieve the multiple effects of aesthetics and increased air supply volume at the same time by simply designing the front panel into a V-shape.

[0043] The present invention provides a wall-mounted air conditioner indoor unit. Figure 1 is a schematic structural diagram of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention, Figure 2 is a schematic front view of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention, Figure 3 is a schematic structural exploded view of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention, Figure 44 is a schematic cross-sectional view of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention, taken along a horizontal plane.

[0044] See also Figures 1 to 4 The wall-mounted air conditioner indoor unit 1 of the present invention includes a casing 10, which is used to constitute the outer shell of the wall-mounted air conditioner indoor unit 1. The casing 10 has an air inlet 11 for introducing indoor air and an air outlet 12 extending in the transverse direction of the casing 10 and used to supply air to the room. Two independent air guide plates 131 and 132 arranged side by side in the transverse direction are provided at the air outlet 12. Each air guide plate is configured to pivot around its own rotating shaft parallel to the extending direction of the air outlet 12 in a controlled manner, so as to adjust the opening and closing state and / or the air outlet direction of the air outlet area corresponding to the air guide plate of the air outlet 12. The rotating shafts of the two air guide plates 131 and 132 may be colinear or parallel to each other. Specifically, one of the air guide plates 131 may be located in the left area of ​​the air outlet 12 to adjust the opening and closing state and / or the air outlet direction of the left area of ​​the air outlet 12; the other air guide plate 132 may be located in the right area of ​​the air outlet 12 to adjust the opening and closing state and / or the air outlet direction of the right area of ​​the air outlet 12. The rotation axes of the air guide plates 131 and 132 are parallel to the extension direction of the air outlet 12. For example, when the air outlet 12 extends in the transverse direction of the housing 10, the rotation axes of the air guide plates 131 and 132 extend in the transverse direction. Specifically, each air guide plate is an elongated plate extending in the direction of its rotation axis. Each air guide plate is a flat plate to reduce the resistance of the air flow passing through it and increase the air supply speed. Alternatively, each air guide plate is a curved plate with a middle portion protruding and bending toward the outside of the housing 10 to guide the air flow to the front side and lower part of the housing 10 to prevent the air flow from blowing straight downward.

[0045] In particular, the wall-mounted air conditioner indoor unit 1 further includes two independent cross-flow fans 21 and 22, which are arranged side by side in the housing 10 in the transverse direction, and each cross-flow fan is configured to rotate around its own rotating shaft in a controlled manner, and the rotating shafts of the two cross-flow fans extend obliquely forward from the two transverse ends of the housing 10 to the middle of the housing 10, respectively, so that the projections of the rotating shafts of the two cross-flow fans in the horizontal plane form a V-shape that gradually tilts forward from the two transverse ends of the housing 10 to the middle thereof, that is, the two cross-flow fans 21 and 22 form a V-shape that gradually tilts forward from the two transverse ends of the housing 10 to the middle thereof. Specifically, the rotating shaft 211 of the cross-flow fan 21 can extend obliquely forward from one transverse end of the housing 10 to the middle of the housing 10, and the rotating shaft 221 of the cross-flow fan 22 can extend obliquely forward from the other transverse end of the housing 10 to the middle of the housing 10.

[0046] Since the two air guide plates are independent, the two crossflow fans are also independent. Therefore, the state of each air guide plate, as well as the pivoting angle, speed and other parameters can be freely set by the user, and the start and stop state, speed and other parameters of each crossflow fan can also be freely set by the user. The state of the air guide plate is combined with the state of the crossflow fan to realize dual-zone air supply in multiple modes, meet the different cooling and heating needs of users in different areas, and improve the user experience. In addition, the rotating shafts of the two crossflow fans 21 and 22 are specially designed to extend forward from the two lateral sides of the casing 10 to the middle of the casing 10, respectively. As a result, the air outlet direction of each crossflow fan is toward the lateral outer side of the casing 10, which breaks through the limitation of the air supply angle of the crossflow fan in the usual setting method of the prior art, and expands the air supply range of the indoor unit.

[0047] Furthermore, the wall-mounted air conditioner indoor unit 1 further includes an evaporator 30, which is used to perform heat exchange with the airflow flowing therethrough, thereby generating a heat exchange airflow with a higher temperature (during heating) or a lower temperature (during cooling). Figure 5 : is a schematic structural diagram of an evaporator according to an embodiment of the present invention. The evaporator 30 is covered on two cross-flow fans 21, 22, and includes a first heat exchange section 31, a second heat exchange section 32 and a third heat exchange section 33 which are sequentially connected from back to front. The first heat exchange section 31 is located at the rear side or the rear upper side of the two cross-flow fans 21, 22, and the third heat exchange section 33 is located at the front side of the two cross-flow fans 21, 22. The first heat exchange section 31 and the third heat exchange section 33 are both V-shaped heat exchange sections extending gradually forward from the lateral ends of the housing 10 to the middle thereof, or curved heat exchange sections extending gradually forward and protruding. In other words, the cross-sections of the first heat exchange section 31 and the third heat exchange section 33 along the horizontal section plane are both V-shaped, extending gradually forward from the lateral ends of the housing 10 to the middle thereof, or arc-shaped, extending gradually forward and protruding.

[0048] The present application breaks through the traditional design concept that the cross-flow fan must be replaced with other fan types in order to increase the evaporator area. The evaporator structure is improved on the basis of using the cross-flow fan as the driving air supply device. The third heat exchange section 33 of the three-stage evaporator located in front of the two cross-flow fans 21 and 22 and the first heat exchange section 31 located in the rear or upper rear side of the two cross-flow fans 21 and 22 are specially designed to be a V-shaped heat exchange section that gradually extends forward from the lateral ends of the casing 10 to the middle of the casing 10 or a curved heat exchange section that gradually bulges forward and extends. Therefore, on the basis of ensuring a simple structure, the lengths of the first heat exchange section 31 and the third heat exchange section 33 are increased at the same time, thereby greatly increasing the effective heat exchange area of ​​the evaporator 30, thereby improving the heat exchange efficiency and the energy consumption level of the indoor unit. In addition, since the first heat exchange section 31 is V-shaped, a roughly triangular or arched space can be formed between the first heat exchange section 31 and the frame of the housing 10, increasing the size of the gap between the two, which is conducive to the rapid permeation of air through the evaporator 30, reducing the resistance of air flow in the housing 10, and reducing the operating noise of the wall-mounted air conditioner indoor unit 1. At the same time, the air supply volume is increased to a certain extent, thereby increasing the air supply volume of the wall-mounted air conditioner indoor unit 1.

[0049] In some embodiments of the present invention, the wall-mounted air conditioner indoor unit 1 may further include two independent fan motors 71 and 72 disposed in the housing 10, and the rotation output shaft of each fan motor is connected to the rotation shaft of a corresponding crossflow fan to drive the crossflow fan to rotate in a controlled manner. Specifically, the rotation output shaft of the fan motor 71 may be connected to the rotation shaft 211 of the crossflow fan 21 to drive the crossflow fan 21 to rotate in a controlled manner. The rotation output shaft of the fan motor 72 may be connected to the rotation shaft 221 of the crossflow fan 22 to drive the crossflow fan 22 to rotate in a controlled manner. The fan motor 71 and the fan motor 72 may be disposed on the lateral outer sides of the crossflow fan 21 and the crossflow fan 22, respectively, and one end of the rotation shaft of the two crossflow fans at the end is respectively connected to the rotation output shaft of the two fan motors, and the other end of the rotation shaft of the two crossflow fans in the middle may be supported on the same bearing seat 73.

[0050] Furthermore, the two fan motors 71, 72 are configured to rotate in a controlled manner in one of three rotation modes, including synchronous rotation of the two fan motors 71, 72, asynchronous rotation of the two fan motors 71, 72, and rotation of any one of the fan motors while the remaining fan motor stops. In other words, the two crossflow fans 21, 22 can rotate synchronously at the same speed to blow out the same air volume, or can rotate asynchronously at different speeds to blow out different air volumes. Alternatively, any one of the crossflow fans rotates while the other one stops, thereby achieving the purpose of adjustable air supply in multiple modes and meeting the different needs of users in different areas.

[0051] In some embodiments of the present invention, the wall-mounted air conditioner indoor unit 1 further includes two independent guide plate motors 81 and 82 disposed in the housing 10, and the rotation output shaft of each guide plate motor is connected to the rotation shaft of a corresponding air guide plate to drive the air guide plate to pivot in a controlled manner. Specifically, the rotation shaft of one of the air guide plates 131 can be connected to the rotation output shaft of one of the guide plate motors 81 to drive the guide plate motor 81 to pivot in a controlled manner; the rotation shaft of the other air guide plate 132 can be connected to the rotation output shaft of one of the guide plate motors 82 to drive the guide plate motor 82 to pivot in a controlled manner.

[0052] Furthermore, the two guide plate motors 81 and 82 are configured to rotate in one of three rotation modes, including synchronous rotation of the two guide plate motors 81 and 82, asynchronous rotation of the two guide plate motors 81 and 82, and rotation of any one of the guide plate motors while the remaining one stops. Thus, the purpose of zoned air supply in multiple modes can be achieved, meeting the different heating and cooling needs of users in different areas.

[0053] Specifically, when the fan motor on a certain side is in operation, the air guide plate on that side is in an open state to better coordinate and adjust the air outlet direction of the area on that side of the air outlet.

[0054] In some embodiments of the present invention, the second heat exchange section 32 may be located above or above the cross-flow fans 21, 22. The second heat exchange section 32 may be a planar heat exchange section; or, the second heat exchange section 32 may be a V-shaped heat exchange section extending from the lateral ends of the casing 10 to the middle thereof and gradually tilting toward the inner side of the cross-flow fans 21, 22. It should be noted that the inner side direction mentioned here means the direction toward the side where the two cross-flow fans 21, 22 are located. For example, when the second heat exchange section 32 is located above the cross-flow fans 21, 22, the second heat exchange section 32 may extend from the lateral ends of the casing 10 to the middle thereof and gradually tilt downward.

[0055] Furthermore, the top edge of the first heat exchange section 31 is adjacent to the rear edge of the second heat exchange section 32, and the shapes are consistent. The front edge of the second heat exchange section 32 is adjacent to the top edge of the third heat exchange section 33, and the shapes are consistent. The inner angle between the first heat exchange section 31 and the second heat exchange section 32 toward the cross flow fans 21, 22, and the inner angle between the second heat exchange section 32 and the third heat exchange section 33 toward the cross flow fans 21, 22 are both smaller than the straight angle, thereby forming a state of half-wrapping the cross flow fans 21, 22 to obtain a better heat exchange effect.

[0056] In some embodiments of the present invention, the third heat exchange section 33 includes two third heat exchange sub-sections 331 extending gradually forward from the lateral ends of the housing 10 to the middle thereof, and the first heat exchange section 31 includes two first heat exchange sub-sections 311 extending gradually forward from the lateral ends of the housing 10 to the middle thereof. The inclination angles of the two first heat exchange sub-sections 311 are respectively consistent with the inclination angles of the rotating shafts of the two cross-flow fans 21 and 22, and the inclination angles of the two third heat exchange sub-sections 331 are respectively consistent with the inclination angles of the rotating shafts of the two cross-flow fans 21 and 22. Thus, uniform gaps can be formed between the two third heat exchange sub-sections 331 and the two cross-flow fans 21 and 22, and between the two first heat exchange sub-sections 311 and the two cross-flow fans 21 and 22, so as to ensure stable air supply, and minimize the space occupied by the evaporator 30 and the cross-flow fans 21 and 22, so as to reduce the volume of the wall-mounted air conditioner indoor unit 1, so as to make it more in line with the development trend of miniaturization.

[0057] In some embodiments of the present invention, the wall-mounted air conditioner indoor unit 1 may further include two independent fan motors 71 and 72 disposed in the housing 10, and the rotation output shaft of each fan motor is connected to the rotation shaft of a corresponding crossflow fan to drive the crossflow fan to rotate in a controlled manner. Specifically, the rotation output shaft of the fan motor 71 may be connected to the rotation shaft 211 of the crossflow fan 21 to drive the crossflow fan 21 to rotate in a controlled manner. The rotation output shaft of the fan motor 72 may be connected to the rotation shaft 221 of the crossflow fan 22 to drive the crossflow fan 22 to rotate in a controlled manner. The fan motor 71 and the fan motor 72 may be disposed on the lateral outer sides of the crossflow fan 21 and the crossflow fan 22, respectively, and one end of the rotation shaft of the two crossflow fans at the end is respectively connected to the rotation output shaft of the two fan motors, and the other end of the rotation shaft of the two crossflow fans in the middle may be supported on the same bearing seat 73.

[0058] Furthermore, the two fan motors 71, 72 are configured to rotate in a controlled manner in one of three rotation modes, including synchronous rotation of the two fan motors 71, 72, asynchronous rotation of the two fan motors 71, 72, and rotation of any one of the fan motors while the remaining fan motor stops. In other words, the two crossflow fans 21, 22 can rotate synchronously at the same speed to blow out the same air volume, or can rotate asynchronously at different speeds to blow out different air volumes. Alternatively, any one of the crossflow fans rotates while the other one stops, thereby achieving the purpose of adjustable air supply in multiple modes and meeting the different needs of users in different areas.

[0059] In some embodiments of the present invention, the housing 10 further includes a front panel 14 for forming its front portion. Further, the housing 10 further includes a frame 16 and a cover 17. In particular, the cross section of the front panel 14 cut along the horizontal section plane is V-shaped, gradually tilting forward from the lateral ends of the housing 10 to the middle of the housing 10. That is, the front panel 14 is roughly a V-shaped plate that gradually tilts forward from the lateral ends of the housing 10 to the middle of the housing 10. As a result, the front panel 14 can be matched with the layout of the two cross-flow fans 21 and 22 and the shape of the third heat exchange section 33. On the one hand, the volume of the wall-mounted air conditioner indoor unit 1 is reduced as much as possible, so that it conforms to the development trend of miniaturization; on the other hand, the air supply volume is further increased, thereby greatly increasing the air supply volume of the wall-mounted air conditioner indoor unit 1. At the same time, the V-shaped front panel 14 gives people a refreshing sense of technology and high-end feeling in appearance. It can be seen that the present invention can achieve multiple effects of beauty and increased air supply volume at the same time by only designing the front panel 14 into a V-shaped simple structural design.

[0060] In some embodiments of the present invention, the front panel 14 may include two vertically placed and symmetrically arranged plates 141, each of which extends obliquely forward from its own first end 141a located at the lateral end of the housing 10 to its own second end 141b located in the middle of the housing 10. In other words, the front panel 14 may be a vertically placed V-shaped plate, with the tip of the V facing the front of the housing 10.

[0061] Further, the second ends 141b of the two plates 141 are fixedly connected by gluing or other suitable means or the two plates 141 are integrally formed. The adjoining part of the second ends 141b of the two plates 141 is located in a vertical bisecting plane extending in the front-to-back direction of the wall-mounted air conditioner indoor unit 1. Specifically, the adjoining part of the second ends 141b of the two plates 141 can be a vertically extending line or surface.

[0062] In some alternative embodiments, the front panel 14 may also be a V-shaped plate placed vertically and tilted, for example, the upper end of the front panel 14 may tilt forward. In this case, the adjoining part of the second ends 141b of the two plates 141 may be a line or surface extending vertically and tilted forward at the upper end.

[0063] Figure 61 is a schematic top view of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention. In some embodiments of the present invention, the air inlet 11 may be formed at the top of the housing 10, and the front edge 111 of the air inlet 11 is adjacent to the top edge 142 of the front panel 14, so that the front edge 111 of the air inlet 11 is consistent in shape with the top edge 142 of the front panel 14. Specifically, since the front panel 14 is roughly a V-shaped plate that gradually protrudes forward from the two lateral ends to the middle, the top edge 142 of the front panel 14 and the front edge of the air inlet 11 are roughly V-shaped that gradually protrudes forward from the two lateral ends of the housing 10 to the middle, so that the front middle part of the air inlet 11 protrudes forward, increasing the area of ​​the air inlet 11, thereby increasing the air intake of the wall-mounted air conditioner indoor unit 1, and further increasing its air supply.

[0064] Since dust is easily accumulated on the top air inlet, the present application further provides a dust prevention mechanism 112 above the air inlet 11 . Figure 7 is a schematic cross-sectional view of a dustproof mechanism according to an embodiment of the present invention, Figure 7 The straight arrow in the figure indicates the direction of air flow. A plurality of curved or bent air guide channels 1121 are formed inside the dustproof mechanism 112. The first end port 1121a of each air guide channel 1121 is connected to the indoor environment, and the second end port 1121b is connected to the air inlet 11. The first end port 1121a of each air guide channel 1121 faces obliquely downward, thereby preventing dust from falling into the air guide channel 1121, thereby preventing dust from falling and accumulating at the air inlet 11, and reducing the burden on the filter device at the air inlet 11.

[0065] In some alternative embodiments, the air inlet 11 may also be formed at the rear of the casing 10. In order to ensure a normal amount of air intake, a bracket may be provided on the rear side of the casing 10 to ensure that a certain distance is maintained between the casing 10 and the wall when the wall-mounted air-conditioning indoor unit 1 is installed on the wall, thereby ensuring normal air intake.

[0066] In some embodiments of the present invention, the air outlet 12 may be located at the front bottom of the housing 10. In order to reduce the mold opening cost and difficulty, the air outlet 12 may still be maintained as a uniform strip-shaped air outlet extending laterally. The housing 10 also includes a V-shaped baffle 15 disposed at the rear side of the lower end of the front panel 14. The front bottom edge of the baffle 15 is adjacent to the bottom edge of the front panel 14 and has the same shape; the rear bottom edge of the baffle 15 is adjacent to the top edge of the air outlet 12 and has the same shape, thereby avoiding mixing of the inlet airflow and the outlet airflow.

[0067] Furthermore, under the driving action of the cross-flow fans 21 and 22, the airflow after heat exchange flows into the room through the air outlet 12. Since the airflow blows out forward and downward at the air outlet 12, a certain negative pressure will be formed near the air outlet 12. The wall-mounted air conditioner indoor unit 1 also includes a guide plate 41, which is arranged at the bottom of the casing 10 and is located below the air outlet 12, and forms a drainage gap 43 with the bottom of the casing 10, so as to allow the natural wind in the room that has not been heat exchanged to flow from back to front through the drainage gap 43 under the action of negative pressure, so as to be mixed with the airflow after heat exchange flowing out of the air outlet 12 and then sent to the room. As a result, not only the air supply volume of the wall-mounted air conditioner indoor unit 1 is increased, but also the mixed wind sent out is softer, more inclined to the normal body sensation index of the human body, and improves the user's comfort experience.

[0068] Regardless of whether the wall-mounted air conditioner indoor unit 1 is in operation or shutdown, the guide plate 41 is always outside the casing 10, and the guide plate 41 will affect the appearance of the entire wall-mounted air conditioner indoor unit 1. Therefore, the appearance design of the guide plate 41 is crucial. To this end, in some embodiments of the present invention, the guide plate 41 is specially designed so that the longitudinal section cut along the vertical section perpendicular to the front-to-back direction is V-shaped, gradually tilting downward from the lateral ends of the casing 10 to the middle of the casing 10. As a result, the entire guide plate 41 can present a V-shaped design similar to the rear wing of a sports car, which improves the texture and high-end feel of the guide plate 41, thereby enhancing the aesthetic effect of the wall-mounted air conditioner indoor unit 1.

[0069] Specifically, in some embodiments, the guide plate 41 may be an integral V-shaped plate. In other embodiments, the guide plate 41 may also be composed of two inclined planar plates fixedly connected and assembled, and the angle between the two planar plates facing the inner side of the housing is an obtuse angle.

[0070] The wall-mounted air conditioner indoor unit 1 may further include a support frame 42 , which is fixedly connected to the outer side of the bottom of the casing 10 and is used to support the guide plate 41 .

[0071] In some embodiments, the guide plate 41 may be fixedly disposed at the bottom of the housing 10 , and in this case, the drainage gap 43 formed between the guide plate 41 and the bottom of the housing 10 is fixed.

[0072] In other embodiments, the guide plate 41 may also be movably disposed at the bottom of the housing 10. In this case, the size of the drainage gap 43 formed between the guide plate 41 and the bottom of the housing 10 is adjustable. Figure 84 is a schematic structural diagram of a wall-mounted air conditioner indoor unit according to another embodiment of the present invention. In these embodiments, the wall-mounted air conditioner indoor unit 1 may also include a swing arm 44, a first end of which is pivotally connected to the support frame 42 through a driving device 45, and a second end is connected to the guide plate 41, so that the position of the guide plate 41 relative to the housing 10 can be adjusted by adjusting the position of the swing arm 44 relative to the support frame 42, thereby adjusting the size of the guide gap 43 and the air outlet direction of the air outlet 12, so as to adjust the air volume of the natural wind in the mixed wind blown out by the indoor unit, thereby adjusting the air supply temperature and air supply softness of the wall-mounted air conditioner indoor unit 1.

[0073] Specifically, the rotation of the swing arm 44 can be intelligently controlled by a remote controller. The driving device 45 can be a driving mechanism having one motor, a plurality of reduction gear sets and a plurality of auxiliary gears, or a driving mechanism having two motors, a central shaft and a plurality of auxiliary gears, or a driving mechanism having a motor and other suitable transmission components.

[0074] Furthermore, the guide plate 41 may include an upper plate 411 facing the casing 10 and a lower plate 412 away from the casing 10, the upper plate 411 is connected to the lower plate 412, and the upper plate 411 is a plastic part, and the lower plate 412 is a metal part. While ensuring the overall strength of the guide plate 41, the weight of the guide plate 41 is reduced, thereby reducing the load of the driving device 45 and ensuring that the guide plate 41 can rotate reliably, stably and smoothly.

[0075] Specifically, the upper plate 411 and the lower plate 412 can be connected by snapping. The lower surface of the upper plate 411 fits the upper surface of the lower plate 412, and the lower surface of the upper plate 411 and the upper surface of the lower plate 412 can be strengthened by gluing.

[0076] In some embodiments of the present invention, the wall-mounted air conditioner indoor unit 1 further includes a gas sensor 51 , a fresh air device 52 , a display light strip 53 and a light strip control panel 54 .

[0077] The gas sensor 51 is disposed on the housing 10 and is used to detect the concentration of carbon dioxide in the indoor environment.

[0078] The fresh air device 52 is disposed in the housing 10 and has a fresh air duct connecting the outdoor environment and the internal space of the housing 10, and is used to start operating in a controlled manner after the carbon dioxide concentration in the indoor environment reaches a preset value, so as to introduce outdoor fresh air into the room. Specifically, the preset value may be a critical value for air health. When the carbon dioxide concentration is higher than the preset value, the air environment is generally considered to be unhealthy; when the carbon dioxide concentration is lower than the preset value, the air environment is generally considered to be healthy. When the indoor carbon dioxide concentration is higher than the preset value used to characterize the health of the space, the fresh air device 52 may start operating automatically in a controlled manner to introduce fresh air into the room; when the indoor carbon dioxide concentration is lower than the preset value used to characterize the health of the space, the fresh air device 52 may stop operating automatically in a controlled manner.

[0079] The display light strip 53 is connected to the light strip control board 54, and the light strip control board 54 is connected to the gas sensor 51 to control the display light strip 53 to display corresponding colors according to the carbon dioxide concentration detected by the gas sensor 51. In other words, when the carbon dioxide concentration in the room is different, the color displayed by the display light strip 53 is also different, thereby intuitively indicating the current indoor air quality status through color.

[0080] Furthermore, the wall-mounted air conditioner indoor unit 1 further includes a support mounting plate 55, which is disposed in the housing 10 and adjacent to the rear side of the front panel 14. The gas sensor 51, the display light strip 53 and the light strip control board 54 are all mounted on the support mounting plate 55. A sensing through hole may be provided on the front panel 14, and the gas sensor 51 is opposite to the sensing through hole to detect the carbon dioxide concentration in the indoor environment through the sensing through hole. The area of ​​the front panel 14 corresponding to the front and rear of the display light strip 53 may be set to be transparent.

[0081] In some embodiments of the present invention, the wall-mounted air conditioner indoor unit 1 further includes a voice interaction system 60. Fig. 9 6 is a schematic structural block diagram of a voice interaction system according to an embodiment of the present invention. The voice interaction system 60 may include a voice receiving module 61, a voice recognition module 62, a voice center control panel 63 and a voice playback module 64. The voice receiving module 61 is used to receive voice signals input from the surrounding environment. The voice recognition module 62 is used to recognize the above voice signal in the wake-up state and generate corresponding voice instructions. The voice center control panel 63 is used to wake up the voice recognition module 62 when the above voice signal is a wake-up signal, and generate corresponding control instructions and feedback information according to the voice instructions recognized and generated by the voice recognition module 62. The voice playback module 64 is used to play the corresponding voice information according to the above control instructions and the above feedback information. The above voice signals may include not only simple voice adjustment signals such as opening, closing, cooling mode, heating mode, operating temperature, etc., but also other suitable complex voice signals such as weather forecasting and song requesting.

[0082] Specifically, the voice receiving module 61 can be a microphone arranged on the rear side of the front panel 14 , and the voice playing module 64 can be a speaker arranged on the rear side of the front panel 14 . The microphone and the speaker can both be mounted on the supporting mounting plate 55 .
