Description

Wall-mounted air conditioner indoor unit

Technical Field

The invention relates to an air conditioner, in particular to a wall-mounted air conditioner indoor unit.

Background technique

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.

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.

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 a very complex structure of this type of wall-mounted indoor unit of the air conditioner, a relatively large volume, and a large operating noise.

Summary of the invention

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.

A further object of the present invention is to improve heat exchange efficiency and reduce operating noise.

Another 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.

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

A casing, comprising an air inlet and an air outlet extending in a transverse direction of the casing, wherein two independent air guide plates are arranged side by side in a transverse direction at the air outlet, each of the air guide plates is configured to pivot around its own rotation axis in a controlled manner to adjust the opening and closing state and/or the air outlet direction of an air outlet area corresponding to the air guide plate of the air outlet, and the rotation axes of the two air guide plates extend obliquely upward from the two transverse ends of the casing to the middle of the casing, respectively, so that the projections of the rotation axes of the two air guide plates in a vertical plane perpendicular to the front-rear direction form an inverted V-shape that gradually tilts upward from the two transverse ends of the casing to the middle of the casing; and

Two independent cross-flow fans are arranged side by side in the horizontal direction in the casing, and each of the cross-flow fans is configured to rotate around its own rotating axis in a controlled manner. The rotating axes of the two cross-flow fans extend forward and obliquely from the two lateral ends of the casing to the middle of the casing, so that the projections of the rotating axes of the two cross-flow fans in the horizontal plane form a V-shape that gradually inclines forward from the two lateral ends of the casing to the middle of the casing.

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

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 third heat exchange section is a V-shaped heat exchange section that extends from the two lateral ends of the casing to the middle thereof gradually away from the outer side of the cross-flow fan or a curved heat exchange section that convexly bends and extends gradually away from the outer side of the cross-flow fan.

Optionally, the third heat exchange section is located in front of the two cross-flow fans, and includes two heat exchange sub-sections that extend gradually forward from the two lateral ends of the casing toward the middle thereof, and the inclination angles of the two heat exchange sub-sections are respectively consistent with the inclination angles of the rotating shafts of the two cross-flow fans.

Optionally, the first heat exchange section is located at the rear side or the upper rear side of the cross flow blower, and the first heat exchange section is a planar heat exchange section to form a triangular space between the first heat exchange section and the two cross flow blowers.

Optionally, each of the air guide plates is an elongated plate extending along the direction of its rotation axis, and the two air guide plates form a V-shape with the tip facing upward;

Each of the air guide plates is a flat plate extending obliquely upward from its rear edge to its front edge, or each of the air guide plates is a curved plate extending upward from its rear edge to its front edge along a downward or upward convex arc.

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.

Optionally, the two air guide plates are further arranged so that when the two air guide plates are in a state of closing the air outlet, the front side edges of the two air guide plates are adjacent to the bottom edge of the front panel and have the same shape; and/or

The front panel includes two vertically placed and symmetrically arranged plates, each of which extends obliquely forward from its first end located at the transverse end of the housing to its second end located in the middle of the housing;

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

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.

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.

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

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 between the guide plate and 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 heat-exchanged airflow flowing out of the air outlet and then being sent to the room.

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.

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.

At the same time, the rotating shafts of the two air guide plates are specially designed to extend upward and obliquely from the two lateral sides of the casing to the middle of the casing. As a result, the distance between each air guide plate and the air outlet can gradually increase from the middle to both sides. That is, the simple design of the position relationship of the two air guide plates breaks through the limitation of the traditional straight guiding method of the air guide plates in the prior art on the air supply range of the indoor unit, increases the air supply angle of the swing blades and the air guide plates, and expands the air supply range of the indoor unit.

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, and the third heat exchange section of the three-stage evaporator located in the front side of the cross-flow fan is specially designed to be a V-shaped heat exchange section that extends from the lateral ends of the casing to the middle of the casing and gradually inclines away from the outside direction of the cross-flow fan, or a curved heat exchange section that gradually convexes and bends and extends toward the outside direction. Therefore, while ensuring the simplicity of the structure, the length of the third heat exchange section is increased, 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.

Furthermore, the first heat exchange section is a plane heat exchange section, and a roughly triangular space can be formed between the first heat exchange section and the two cross-flow fans, 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 wall-mounted air conditioner indoor unit.

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 multiple effects of aesthetics and increased air supply volume at the same time by simply designing the front panel into a V-shape.

Based on the following detailed description of specific embodiments of the present invention in conjunction with the accompanying drawings, those skilled in the art will become more aware of the above and other objects, advantages and features of the present invention.

Detailed ways

The present invention provides a wall-mounted air-conditioning indoor unit. FIG1 is a schematic structural diagram of a wall-mounted air-conditioning indoor unit according to an embodiment of the present invention. FIG2 is a schematic front view of a wall-mounted air-conditioning indoor unit according to an embodiment of the present invention. FIG3 is a schematic structural decomposition diagram of a wall-mounted air-conditioning indoor unit according to an embodiment of the present invention. FIG4 is a schematic sectional view of a wall-mounted air-conditioning indoor unit taken along a horizontal plane according to an embodiment of the present invention.

Referring to Fig. 1 to Fig. 4, the wall-mounted air conditioner indoor unit 1 of the present invention comprises a housing 10, which is used to constitute the outer shell of the wall-mounted air conditioner indoor unit 1. The housing 10 has an air inlet 11 for introducing indoor air and an air outlet 12 extending in the transverse direction of the housing 10 and used to supply air to the room, and 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 in a controlled manner 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. Specifically, one of the air guide plates 131 can 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 can 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.

In particular, the rotation axes of the two air guide plates extend obliquely upward from the two lateral ends of the casing 10 to the middle of the casing 10, respectively, so that the projections of the rotation axes of the two air guide plates in the vertical plane perpendicular to the front-rear direction form an inverted V-shape that gradually tilts upward from the lateral ends of the casing 10 to the middle thereof. That is to say, the rotation axis of one of the air guide plates 131 extends obliquely upward from one lateral end of the casing 10 to the middle of the casing 10, and the rotation axis of the other air guide plate 132 extends obliquely upward from the other lateral end of the casing 10 to the middle of the casing 10, so that the rotation axes of the two air guide plates form a roughly inverted V-shaped structure. As a result, the distance between each air guide plate and the air outlet 12 can be gradually increased from the middle to both sides, that is, the simple design of the arrangement of the two air guide plates breaks through the limitation of the air supply range of the indoor unit by the traditional straight-direction guiding method of the air guide plates in the prior art, increases the air supply wide angle of the swing blades and the air guide plates in the lateral direction, and expands the air supply range of the indoor unit.

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 forward from the 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 gradually tilted forward from the transverse ends of the housing 10 to the middle thereof, that is, the two cross-flow fans 21 and 22 form a V-shape gradually tilted forward from the transverse ends of the housing 10 to the middle thereof. Specifically, the rotating shaft 211 of the cross-flow fan 21 can extend forward from one of the transverse ends of the housing 10 to the middle thereof, and the rotating shaft 221 of the cross-flow fan 22 can extend forward from the other transverse end of the housing 10 to the middle thereof.

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.

In some embodiments of the present invention, each air guide plate is a slender plate extending along the direction of its rotation axis, and the two air guide plates form a V-shape with the tip facing upward. In other words, the air guide plates 131 and 132 are both slender plates extending gradually upward from one lateral end of the housing 10 to the middle of the housing 10, so that the air guide plates 131 and 132 form a substantially V-shaped structure with the tip facing upward, thereby expanding the air supply angle of the air outlet 12 in the lateral direction.

Furthermore, each air guide plate is a flat plate extending upwardly from its rear edge to its front edge, so as to reduce the resistance of airflow passing through it and increase the air supply speed. Alternatively, each air guide plate is a curved plate extending upwardly along a downwardly convex arc from its rear edge to its front edge, so as to guide the airflow to flow toward the front and lower side of the housing 10 and prevent the airflow from blowing directly downward. In other embodiments, each air guide plate can also be a curved plate extending upwardly along an upwardly convex arc from its rear edge to its front edge.

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 respectively disposed on the lateral outer sides of the crossflow fan 21 and the crossflow fan 22, 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.

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.

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.

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.

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.

In some embodiments of the present invention, the wall-mounted air conditioner indoor unit 1 further includes an evaporator 30, which is used to perform heat exchange with the air flow passing through it, thereby generating a heat exchange air flow with a higher temperature (when heating) or a lower temperature (when cooling). FIG. 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 and 22, and includes a first heat exchange section 31, a second heat exchange section 32 and a third heat exchange section 33 connected in sequence from back to front. In particular, the third heat exchange section 33 is a V-shaped heat exchange section extending from the lateral ends of the housing 10 to the middle thereof gradually in an inclined direction away from the outer side of the cross-flow fans 21 and 22, or a curved heat exchange section extending convexly and curvedly in a direction away from the outer side of the cross-flow fans 21 and 22. It should be noted that the outer direction mentioned here means the direction away from the side where the two cross-flow fans 21 and 22 are located, and accordingly, the direction toward the side where the two cross-flow fans 21 and 22 are located is the inner direction opposite to the outer direction.

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 is specially designed to be a V-shaped heat exchange section that extends from the lateral ends of the casing 10 to the middle of the casing 10 and gradually extends away from the outside direction of the cross-flow fans 21 and 22, or a curved heat exchange section that gradually convexes and bends and extends in the outside direction. Therefore, on the basis of ensuring the simplicity of the structure, the length of the third heat exchange section 33 is increased, thereby 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.

When the third heat exchange section 33 is located at different sides of the cross flow fans 21 and 22, its outer directions away from the cross flow fans 21 and 22 are also different. In some embodiments of the present invention, the third heat exchange section 33 is located at the front side of the two cross flow fans 21 and 22. At this time, the outer direction of the third heat exchange section 33 away from the cross flow fans 21 and 22 can be the forward direction, and the third heat exchange section 33 extends from the lateral ends of the housing 10 to the middle thereof and gradually tilts forward. Specifically, the third heat exchange section 33 may include two heat exchange sub-sections 331 extending from the lateral ends of the housing 10 to the middle thereof and gradually tilts forward, and the inclination angles of the two 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, a uniform gap can be formed between the two heat exchange sub-sections 331 and the two cross-flow fans 21, 22 to ensure stable air supply and minimize the space occupied by the evaporator 30 and the cross-flow fans 21, 22 to reduce the volume of the wall-mounted air-conditioning indoor unit 1, making it more in line with the development trend of miniaturization.

In some embodiments of the present invention, the first heat exchange section 31 is located at the rear side or the rear upper side of the crossflow fans 21 and 22, and the first heat exchange section 31 is a plane heat exchange section, so as to form a triangular space between the first heat exchange section 31 and the two crossflow fans 21 and 22, thereby increasing the size of the gap between the first heat exchange section 31 and the two crossflow fans 21 and 22, which is conducive to the rapid permeation of air through the evaporator 30, reducing the resistance of air flow in the casing 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.

Further, the second heat exchange section 32 may be above or above the crossflow fans 21, 22, and the second heat exchange section 32 may be a plane heat exchange section. The inner angle between the first heat exchange section 31 and the second heat exchange section 32 toward the crossflow fans 21, 22, and the inner angle between the second heat exchange section 32 and the third heat exchange section 33 toward the crossflow fans 21, 22 are both smaller than a straight angle, thereby forming a state of half-wrapping the crossflow fans 21, 22 to obtain a better heat exchange effect. Further, 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.

In some embodiments of the present invention, the housing 10 further includes a front panel 14 for forming the front portion thereof. 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 gradually tilting forward from the lateral ends of the housing 10 to the middle of the housing 10. Thus, 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.

In some embodiments of the present invention, the two air guide plates 131, 132 are further configured so that when the two air guide plates 131, 132 are both in a state of closing the air outlet 12, the front side edges of the two air guide plates 131, 132 are adjacent to the bottom edge 144 of the front panel 14, and the shapes are consistent. Specifically, the bottom edge 144 on the left side of the front panel 14 can be adjacent to the front side edge 131a of the air guide plate 131, and the shapes are consistent, that is, the front side edge 131a of the air guide plate 131 also extends from one of the lateral ends of the housing 10 to the middle thereof gradually forward and tilted. The bottom edge 144 on the right side of the front panel 14 can be adjacent to the front side edge 132a of the air guide plate 132, and the shapes are consistent, that is, the front side edge 132a of the air guide plate 132 also extends from the other lateral end of the housing 10 to the middle thereof gradually forward and tilted.

Furthermore, the rear edge 131 b of the air guide plate 131 and the rear edge 132 b of the air guide plate 132 are both adjacent to the edge of the V-shaped blocking plate 15 and have the same shape.

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.

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.

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.

Fig. 6 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 thereof, 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 volume of the wall-mounted air conditioner indoor unit 1, and further increasing its air supply volume.

Since dust is easily accumulated at the top air inlet, the present application further sets a dustproof mechanism 112 above the air inlet 11. FIG7 is a schematic cross-sectional view of a dustproof mechanism according to an embodiment of the present invention, and the straight arrow in FIG7 is the direction of airflow. A plurality of curved or bent air guide channels 1121 are formed inside the dustproof mechanism 112, and 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, and the first end port 1121a of each air guide channel 1221 faces obliquely downward, thereby preventing dust from falling into the air guide channel 1121, thereby avoiding dust accumulation and other problems at the air inlet 11, and reducing the burden of the filter device at the air inlet 11.

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.

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 mold opening costs and mold opening difficulty, the air outlet 12 may still be maintained as a uniform strip-shaped air outlet extending in the transverse direction. The housing 10 further includes a V-shaped blocking plate 15 disposed at the lower end of the front panel 14 to prevent the inlet air flow from mixing with the outlet air flow.

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.

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.

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.

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 .

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.

In other embodiments, the guide plate 41 may also be movably disposed at the bottom of the casing 10, in which case the size of the drainage gap 43 formed between the guide plate 41 and the bottom of the casing 10 is adjustable. FIG8 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 as to adjust the position of the guide plate 41 relative to the casing 10 by adjusting the position of the swing arm 44 relative to the support frame 42, thereby adjusting the size of the drainage 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.

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.

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.

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.

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 .

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

The fresh air device 52 is disposed in the casing 10 and has a fresh air duct connecting the outdoor environment and the internal space of the casing 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.

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.

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.
