Description

[Technical Field]

[0001] [Cross-Citation of Related Applications] This application is based on and claims priority from a Chinese patent application having Chinese patent application number 202110611186.4 and filing date June 1, 2021, the entire contents of which are hereby incorporated by reference into this application.

[0002] The present invention relates to the field of air conditioners, and more particularly to wall-mounted air conditioners. [Background technology]

[0003] In the related art, the air intake of a wall-mounted air conditioner is located at its top, and in order to meet the requirement of suction from the top, the wall-mounted air conditioner must be located at a relatively large distance from the ceiling wall of the room, which results in low indoor space utilization and makes the indoor space appear more cramped. In addition, the wall-mounted air conditioner of the related art has the disadvantage of low heat exchange efficiency. Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention aims to solve at least one of the technical problems of the related art to some extent. To this end, an embodiment of the present invention proposes a wall-mounted air conditioner. [Means for solving the problem]

[0005] A wall-mounted air conditioner according to an embodiment of the present invention includes a casing, electrical control components, and a heat exchanger, wherein an air duct is arranged within the casing, the air duct has an intake port and an outlet port, the air duct includes an intake segment and an outlet segment connected to each other, at least a portion of the intake port is located on the front side of the casing, an installation space is formed between the front panel of the casing and the air duct, the installation space is located in front of and below the internal space of the casing, the heat exchanger is provided within the air duct, and the electrical control components are provided within the installation space.

[0006] By positioning at least a portion of the air inlet of the wall-mounted air conditioner according to the present invention on the front side of the casing, it is possible to allow ambient air (intake) to enter the air duct from approximately the front side of the casing. For example, the ambient air (intake) may enter the air duct from directly in front of the casing, from the upper front side of the casing, or from the lower front side of the casing. Furthermore, the ambient air may enter the air duct from at least two directions selected from the directly in front, the upper front, and the lower front side of the casing.

[0007] In other words, ambient air does not need to enter the air duct from directly above the casing. This significantly reduces or eliminates the distance between the wall-mounted air conditioner and the ceiling or wall of the room, improving the utilization rate of the indoor space and effectively reducing or eliminating the feeling of crampedness in the indoor space, especially in low-height rooms.

[0008] Therefore, the wall-mounted air conditioner according to the embodiment of the present invention has very low requirements for installation space, and the installation space only needs to be large enough to accommodate the wall-mounted air conditioner; there is no need to ensure an intake space above the wall-mounted air conditioner, which can expand the range of application of wall-mounted air conditioners.

[0009] In some embodiments, the portion located in front of the air inlet is inclined obliquely upward from the vertical plane toward the wall surface (which can be understood as the mounting surface). In this way, when the user is standing on the floor in a room, the user cannot see the inside of the casing (wall-mounted air conditioner) from the air inlet, and the internal structure of the casing (wall-mounted air conditioner) is not exposed to the user, thereby improving the visual comfort of the user.

[0010] Furthermore, when suction is performed from the top, the space at the top is often limited and relatively narrow, limiting the suction volume. In the technical solution of the present application, at least a portion of the suction port is located at the front of the casing, so that air entering the air duct through the suction port can flow directly into the heat exchanger and fully exchange heat with the heat exchanger. In other words, the suction volume of the wall-mounted air conditioner is not limited by the narrow space at the top, and by suctioning from the front of the casing, the suction volume can be effectively increased, and the flow rate of air flowing through the heat exchanger can be significantly increased, greatly improving the heat exchange efficiency of the heat exchanger.

[0011] In this application, at least a portion of the air inlet is located on the front surface of the casing, eliminating the need to provide a generally inverted-V-shaped heat exchanger below the air inlet, and eliminating the need to provide a water tray at the lower end of the generally inverted-V-shaped heat exchanger with a width greater than the width of the generally inverted-V-shaped heat exchanger, since the water tray will block the flow of air to the heat exchanger and prevent substantial heat exchange between the heat exchanger and the air. Because at least a portion of the air inlet is located on the front surface of the casing, the water tray will not block the flow of air to the heat exchanger, and the water tray will not pass through the airflow path to the heat exchanger, thereby significantly improving the heat exchange efficiency of the heat exchanger. Optionally, the water tray is provided below the heat exchanger.

[0012] Therefore, the wall-mounted air conditioner according to the embodiment of the present invention has the advantages of being easy to install, improving the utilization rate of indoor space, wide application range, and high heat exchange efficiency.

[0013] In addition, the wall-mounted air conditioner provided by the present invention has an installation space located at the front and bottom of the interior space of the casing. The electrical control components are installed in this installation space, so that the installation of the electrical control components does not occupy the longitudinal space of the main body, shortening the length of the main body and improving the space utilization and integration of the wall-mounted air conditioner, resulting in a more compact and rational structure of the wall-mounted air conditioner. Furthermore, the installation of the electrical control components does not occupy the effective suction surface of the heat exchanger or sacrifice the heat exchange efficiency of the heat exchanger, thereby improving the performance of the wall-mounted air conditioner. Furthermore, because the installation space is located behind the front panel of the casing, users do not need to remove the entire casing when wiring, assembling / removing, testing, or repairing the electrical control components; they only need to remove the front panel, which greatly increases the convenience of testing and repair and improves operational comfort.

[0014] As a result, the wall-mounted air conditioner provided by the embodiment of the present invention has the advantages of high space utilization rate inside the machine body, compact structure, short length, and convenient test and repair.

[0015] In some embodiments, the intake port is provided in the front panel, the intake segment extends horizontally or diagonally forward from the outlet segment, a portion of the outlet segment adjacent to the outlet port extends downward and forward from the remainder of the outlet segment, and the mounting space is formed between the intake segment, the outlet segment, and the front panel.

[0016] In some embodiments, the airway wall of the suction segment includes a first suction plate and a second suction plate, and the airway wall of the discharge segment includes a first discharge plate and a second discharge plate, and the second suction plate, the second discharge plate, and the front plate define the mounting space between them.

[0017] In some embodiments, the second suction plate includes a recess forming a water receiving channel for receiving condensed water from the heat exchanger.

[0018] In some embodiments, the water receiving groove is located on one side of the recess and the mounting space is located on the other side of the recess.

[0019] In some embodiments, the wall-mounted air conditioner further includes a thermal insulation layer positioned between the electrical control component and the air duct.

[0020] In some embodiments, the electrical control components include a protective housing including a box body and a box cover, the box body and box cover connected to define a sealed fire chamber, and electrical elements located within the fire chamber.

[0021] In some embodiments, the electrical elements include a main board and components, the main board being parallel to the bottom plate of the box body and spaced apart from the bottom plate, and the components being attached to a surface of the main board facing away from the bottom plate.

[0022] In some embodiments, the front plate is an arc-shaped plate that protrudes forward and includes an upper plate portion and a lower plate portion, the air outlet is provided in the upper plate portion, the mounting space is located rearward of the lower plate portion, the bottom plate is provided at an angle, and the lower end of the bottom plate is located rearward of the upper end of the bottom plate.

[0023] In some embodiments, the components include a first set of components and a second set of components, wherein a height of the first set of components is greater than a preset value, a height of the second set of components is less than or equal to the preset value, and a position of the second set of components is higher than a position of the first set of components.

[0024] In some embodiments, the angle between the centerline of the suction segment and the centerline of the outlet segment is greater than or equal to 10 degrees and less than or equal to 85 degrees.

[0025] Additional features and advantages of the present invention will be set forth in part in the description that follows, and in part will be obvious from the description, or may be learned by practice of the present invention. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0027] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings, examples of which are illustrated in the accompanying drawings. The following description of the preferred embodiments is for illustrative purposes only and should not be construed as limiting the present invention.

[0028] The present invention is based on the inventor's discovery and recognition of the following facts and problems.

[0029] In the related art, as shown in Figure 4, the air intake port of a wall-mounted air conditioner 1' is located at the top, and the distance between the top of the wall-mounted air conditioner 1' and the indoor ceiling wall 3 must be large to form an intake space, so the wall-mounted air conditioner 1' cannot be installed in close contact with the indoor ceiling wall 3. The heat exchanger 10' of the wall-mounted air conditioner 1 is installed around the cross-flow fan wheel 20'. Specifically, the approximately inverted V-shaped first section 11' of the heat exchanger 10' is located above the cross-flow fan wheel 20', and the second section 12' of the heat exchanger 10' is located in front of the cross-flow fan wheel 20'.

[0030] A water tray 30 is provided below the lower rear end 111' of the first section 11'. The water tray 30' faces the lower rear end 111' of the first section 11' in the vertical direction, and is located between the lower rear end 111' of the first section 11' and the cross-flow fan wheel 20'. The inventors recognized that if the lower rear end 111' of the first section 11' is blocked by the water tray 30', the lower rear end 111' of the first section 11' will not substantially exchange heat with the air, resulting in waste and reducing heat exchange efficiency.

[0031] An intake duct 50' is defined between the second section 12' and the front panel 40' of the wall-mounted air conditioner 1'. However, the inventors recognized that because most of the space in the front-to-rear direction of the wall-mounted air conditioner 1' is occupied by the heat exchanger 10', cross-flow fan wheel 20', and scroll casing 60', the intake duct 50' is relatively narrow, i.e., the flow rate of air flowing through the intake duct 50' is small, and therefore the heat exchange efficiency of the second section 12' is low.

[0032] The inventors also discovered that in related art, electrical control components of wall-mounted air conditioners are mounted on the longitudinal sides (e.g., the left and / or right sides) of the air conditioner body. Typically, there are two approaches: one in which the electrical control components and the duct system, such as the distributor, are located on the same side, and the other in which the electrical control components and the duct system, such as the distributor, are mounted on two longitudinal sides of the body. However, in both approaches, the electrical control components occupy space in the longitudinal direction of the air conditioner body, lengthening the body. If the length of the air conditioner body remains the same, locating the electrical control components and the ducts on the same side compresses the duct space, increasing the risk of friction or collision with the ducts. If the electrical control components are mounted on the longitudinal sides of the heat exchanger, they may occupy the heat exchanger's effective suction surface, sacrificing the heat exchange efficiency of the heat exchanger. Furthermore, if the electrical control components are mounted on the longitudinal sides of the air conditioner body, the casing must be removed for repair or removal, making repairs more difficult.

[0033] A wall-mounted air conditioner 1 according to an embodiment of the present invention will be described below with reference to Figures 1 to 3. As shown in Figure 1, the wall-mounted air conditioner 1 includes a casing 10, a heat exchanger 20, an air duct 30, and an electric control component 90. Here, the air duct 30 is provided within the casing 10, and the heat exchanger 20 is located within the air duct 30. The air duct 30 has an air inlet 311 and an air outlet 312, and includes an air inlet segment 313 and an air outlet segment 314 that are connected to each other. Here, the air inlet 311 is located in the air inlet segment 313, and the air outlet 312 is located in the air outlet segment 314.

[0034] At least a portion of the suction port 311 is located on the front surface 11 of the casing 10. The front surface 11 of the casing 10 is a surface that can be seen when the casing 10 is line-of-sight horizontally behind the casing 10, i.e., a surface of the casing 10 that can be seen when the casing 10 is line-of-sight horizontally behind the casing 10 is the front surface 11 of the casing 10. For example, when an observer's eyes are located at approximately the same horizontal height as the casing 10 and the observer is located in front of the casing 10, a surface of the casing 10 that the observer can see is the front surface 11 of the casing 10.

[0035] The front-to-back direction is indicated by arrow A in Figure 1, and the up-down direction is indicated by arrow B in Figure 1. For example, wall-mounted air conditioner 1 can be mounted on wall surface 2. The direction horizontally away from wall surface 2 is the true direction, and the direction horizontally away from wall surface 2 is the true rear direction.

[0036] An installation space 50 is formed between the front panel 111 of the casing 10 and the air duct 30. The electrical control components 90 are provided in the installation space 50. The installation space 50 is located at the front and bottom of the interior space of the casing 10, i.e., the electrical control components 90 are installed at the front and bottom of the interior space of the casing 10.

[0037] By positioning at least a portion of the air inlet of the wall-mounted air conditioner according to the present invention on the front side of the casing, it is possible to allow ambient air (intake) to enter the air duct from approximately the front side of the casing. For example, the ambient air (intake) may enter the air duct from directly in front of the casing, from the upper front side of the casing, or from the lower front side of the casing. Furthermore, the ambient air may enter the air duct from at least two directions selected from the directly in front, the upper front, and the lower front side of the casing.

[0038] In other words, ambient air does not need to enter the air duct from directly above the casing. This significantly reduces or eliminates the distance between the wall-mounted air conditioner and the ceiling or wall of the room, improving the utilization rate of the indoor space and effectively reducing or eliminating the feeling of crampedness in the indoor space, especially in low-height rooms.

[0039] Therefore, the wall-mounted air conditioner according to the embodiment of the present invention has very low requirements for installation space, and the installation space only needs to be large enough to accommodate the wall-mounted air conditioner; there is no need to ensure an intake space above the wall-mounted air conditioner, which can expand the range of application of wall-mounted air conditioners.

[0040] In some embodiments, the portion located in front of the air inlet 311 is inclined obliquely upward relative to the vertical plane toward the wall surface 2 (which can be understood as the mounting surface). In this way, when the user is standing on the floor in a room, the user cannot see the inside of the casing 10 (wall-mounted air conditioner 1) from the air inlet 311, and the internal structure of the casing 10 (wall-mounted air conditioner 1) is not exposed to the user, thereby improving the visual comfort of the user.

[0041] Furthermore, when suction is performed from the top, the space at the top is often limited and relatively narrow, limiting the suction volume. In the technical solution of the present application, at least a portion of the suction port is located at the front of the casing, so that air entering the air duct through the suction port can flow directly into the heat exchanger and fully exchange heat with the heat exchanger. In other words, the suction volume of the wall-mounted air conditioner is not limited by the narrow space at the top, and by suctioning from the front of the casing, the suction volume can be effectively increased, the air flow rate through the heat exchanger can be significantly increased, and the heat exchange efficiency of the heat exchanger can be greatly improved.

[0042] In this application, at least a portion of the air inlet is located on the front surface of the casing, eliminating the need to provide a generally inverted-V-shaped heat exchanger below the air inlet, and eliminating the need to provide a water tray at the lower end of the generally inverted-V-shaped heat exchanger with a width greater than the width of the generally inverted-V-shaped heat exchanger, since the water tray will block the flow of air to the heat exchanger and prevent substantial heat exchange between the heat exchanger and the air. Because at least a portion of the air inlet is located on the front surface of the casing, the water tray will not block the flow of air to the heat exchanger, and the water tray will not pass through the airflow path to the heat exchanger, thereby significantly improving the heat exchange efficiency of the heat exchanger. Optionally, the water tray is provided below the heat exchanger.

[0043] Therefore, the wall-mounted air conditioner according to the embodiment of the present invention has the advantages of being easy to install, improving the utilization rate of indoor space, wide application range, and high heat exchange efficiency.

[0044] In addition, the wall-mounted air conditioner provided in accordance with the present invention has an installation space located at the front and bottom of the interior space of the casing. The electrical control components are installed in this installation space, eliminating the need to occupy longitudinal space in the main body, shortening the length of the main body and improving the space utilization and integration of the wall-mounted air conditioner, resulting in a more compact and streamlined structure. Furthermore, the installation of the electrical control components does not occupy the effective intake surface of the heat exchanger or sacrifice the heat exchange efficiency of the heat exchanger, thereby improving the performance of the wall-mounted air conditioner. Furthermore, because the installation space is located behind the front panel of the casing, users do not need to remove the entire casing when wiring, assembling / removing, testing, or repairing the electrical control components; they only need to remove the front panel, significantly increasing the convenience of testing and repair and improving operational comfort.

[0045] As a result, the wall-mounted air conditioner provided by the embodiment of the present invention has the advantages of high space utilization rate inside the machine body, compact structure, short length, and convenient test and repair.

[0046] Specific embodiments provided by the present invention will be described in detail below in conjunction with Figures 1 and 2. In some embodiments, a wall-mounted air conditioner 1 can be mounted on a wall surface 2 in a room.

[0047] 1 and 2, the wall-mounted air conditioner 1 includes a casing 10, a heat exchanger 20, an air duct 30 provided within the casing 10, a fan wheel 40 provided in the air duct 30, and an electric control component 90. The casing 10 includes a front panel 111, and an air intake 311 is provided in the front panel 111. The electric control component 90 is mounted in a mounting space 50 formed between the front panel 111 of the casing 10 and the air duct 30.

[0048] In some embodiments, when the casing 10 is attached to the wall surface 2, the distance between the top surface of the casing 10 and the ceiling wall 3 of the room is 20 centimeters or less. In other words, the minimum vertical distance between the casing 10 and the ceiling wall 3 of the room is 20 centimeters or less. This can further improve the utilization rate of the indoor space.

[0049] Alternatively, the distance between the top surface of the casing 10 and the ceiling wall 3 of the room is 15 centimeters or less. Alternatively, the distance between the top surface of the casing 10 and the ceiling wall 3 of the room is 10 centimeters or less. Alternatively, the distance between the top surface of the casing 10 and the ceiling wall 3 of the room is 8 centimeters or less. Alternatively, the distance between the top surface of the casing 10 and the ceiling wall 3 of the room is 5 centimeters or less. Alternatively, the top surface of the casing 10 is in contact with the ceiling wall 3 of the room, i.e., the distance between the top surface of the casing 10 and the ceiling wall 3 of the room is equal to 0 centimeters. This can further improve the utilization rate of the indoor space.

[0050] The air duct 30 includes an intake segment 313 and an outlet segment 314 connected to each other, the intake segment 313 defining an intake passage 3136, and the outlet segment 314 defining an outlet passage 3143. The intake port 311 of the air duct 30 is located at one end of the intake passage 3136, and the outlet port 312 of the air duct 30 is located at one end of the outlet passage 3143. The heat exchanger 20 is located in the intake passage 3136 and is provided at the intake port 311, facing the intake port 311 to exchange heat with the air entering the intake passage 3136 from the intake port 311.

[0051] A part of fan wheel 40 is located in suction passage 3136, and the other part of fan wheel 40 is located in discharge passage 3143. Fan wheel 40 generates a blowing wind force so that air enters suction passage 3136 from suction port 311, passes through fan wheel 40, enters discharge passage 3143, and is finally discharged from the discharge port. By providing fan wheel 40 in air passage 30, the flow rate and flow speed of air flowing through heat exchanger 20 can be improved, further improving the heat exchange efficiency between heat exchanger 20 and wall-mounted air conditioner 1.

[0052] As shown in FIG. 1, the suction segment 313 extends diagonally forward and upward from the outlet segment 314 ; in other words, the suction segment 313 extends diagonally forward and upward from its connection with the outlet segment 314 .

[0053] In other optional embodiments, the suction segment 313 may further extend horizontally forward from the point where it connects to the outlet segment 314, or the suction segment 313 may further extend downward and forward from the point where it connects to the outlet segment 314. Preferably, in some embodiments, the suction segment 313 extends diagonally upward and forward from the point where it connects to the outlet segment 314, so as to make the structure of the wall-mounted air conditioner 1 more rational.

[0054] The portion of the blow-out segment 314 adjacent to the blow-out outlet 312 extends downward and forward from the remaining portion of the blow-out segment 314, in other words, the blow-out segment 314 includes a portion adjacent to the blow-out outlet 312 and a remaining portion other than this portion, and the portion of the blow-out segment 314 adjacent to the blow-out outlet 312 extends downward and forward from the point where it is connected to the remaining portion. The blow-out outlet 312 is provided in the lower part of the casing 10.

[0055] By setting the suction segment 313 and the discharge segment 314 as described above, the air passage 30 is configured in a generally V-shape that opens forward, and the suction segment 313 is located above a portion of the discharge segment 313 that is adjacent to the discharge port 312. An installation space 50 is defined between the suction segment 313, the discharge segment 314, and the front panel 111. The electrical control component 90 is mounted in the installation space 50, which is located in front of and below the internal space of the casing 10. In other optional embodiments, the installation space 50 located in front of and below the internal space of the casing 10 may be formed in other shapes, and is not limited to these shapes in the present application.

[0056] 1 and 2 , in some embodiments, the front panel 111 is an arc-shaped panel that protrudes forward, and includes an upper panel portion 1111 and a lower panel portion 1112. The upper panel portion 1111 is an upper portion of the front panel 111, and the lower panel portion 1112 is a lower portion of the front panel 111, and the upper panel portion 1111 is located above the lower panel portion 1112. The air outlet 312 is provided in the upper panel portion 1111, and the mounting space 50 is located behind the lower panel portion 1112, and the mounting space 50 is located below the air inlet 312.

[0057] Furthermore, the air passage wall of the suction segment 313 includes a first suction plate 3131 and a second suction plate 3132, which together define an suction passage 3136. The air passage wall of the blow-out segment 314 includes a first blow-out plate 3141 and a second blow-out plate 3142, which together define an outlet passage 3143. For example, the first blow-out plate 3141 has a worm tongue structure, and the second blow-out plate 3142 has a worm wheel structure.

[0058] The mounting space 50 is defined between the second suction plate 3132, the second discharge plate 3142, and the front plate 111. Specifically, as shown in Figures 1 and 2, the mounting space 50 is defined between a side surface 31321 of the second suction plate 3132 that faces away from the suction passage 3136, a side surface 31421 of the second discharge plate 3142 that faces away from the discharge passage 3143, and the rear surface 1110 of the front plate 111.

[0059] Optionally, the first suction plate 3131 and the first blowing plate 3141 are connected to form an integral first wall, and the second suction plate 3132 and the second blowing plate 3142 are connected to form an integral second wall, and the mounting space 50 is defined by the second wall and the front plate 111.

[0060] 1 and 2, the heat exchanger 20 is fitted into the suction port of the suction segment 313, the upper end of the heat exchanger 20 is fitted into the first suction plate 3131, and a first seal structure (not shown) is provided between the upper end and the first suction plate 3131, and the lower end of the heat exchanger 20 is fitted into the second suction plate 3132, and a second seal structure (not shown) is provided between the lower end and the second suction plate 3132. The first seal structure and the second seal structure are used to seal so as to prevent air that has not undergone heat exchange through the heat exchanger 20 from entering the suction passage 3136 through a gap between the heat exchanger 20 and the first suction plate 3131 or a gap between the heat exchanger 20 and the second suction plate 3132 and affecting the cooling effect of the air conditioner. Optionally, the first seal structure and the second seal structure are sealing foams.

[0061] 1 and 2 , the second suction plate 3132 includes a recess 3133 that forms a water receiving groove 3134 for receiving condensed water from the heat exchanger 20, which generates condensed water during heat exchange. To prevent the condensed water from flowing into the discharge passage 3143 and flowing out of the discharge port 312, the second suction plate 3132 includes a recess 3133 that forms a water receiving groove 3134 for receiving condensed water from the heat exchanger 20. The water receiving groove 3134 is located on one side of the recess 3133, closer to the suction passage 3136, and the mounting space 50 is located on the other side of the recess. For example, the recess 3133 may be formed by a portion of the second suction plate 3132 being recessed in a direction away from the suction passage 3136, and the recess 3133 may be seen as a portion of the second suction plate 3132 protruding into the mounting space 50. The mounting space 50 is located on the opposite side of the recess 3133 from the water receiving groove 3134. The recess 3133 forms a water receiving groove 3134, so the recess 3133 can also be called a water receiving tray.

[0062] In the embodiment shown in Figures 1 and 2, the opening of the water receiving groove 3134 faces upward, the water receiving groove 3134 has a certain depth in the vertical direction, the water receiving groove 3134 is located behind the lower end of the heat exchanger 20, i.e., behind the second seal structure, and the water receiving groove 3134 is also located below the heat exchanger 20 in order to effectively receive condensed water from the heat exchanger 20.

[0063] Furthermore, a portion of the first suction plate 3131 is recessed outward to form an avoidance groove 3135, which is located behind the upper end of the heat exchanger 20, i.e., behind the first seal structure. The avoidance groove 3135 avoids condensed water generated during heat exchange by the heat exchanger 20, and prevents the condensed water from flowing along the first suction plate 3131 into the blow-out segment 314. Optionally, a portion of the first suction plate 3131 adjacent to the blow-out segment 314 is recessed outward to form the avoidance groove 3135. For example, the avoidance groove 3135 may be formed by a portion of the second suction plate 3132 being recessed in a direction away from the suction passage 3136, and the avoidance groove 3135 may be seen as being formed by a portion of the second suction plate 3132 protruding outward.

[0064] Furthermore, in some embodiments, the wall-mounted air conditioner 1 further includes a thermal insulation layer 70 located between the electric control component 90 and the air duct 30. In the embodiment shown in Figures 1 and 2, the thermal insulation layer 70 is located between the second wall and the electric control component 90, that is, the thermal insulation layer 70 is located between the electric control component 90 and the second suction plate 3132, and between the electric control component 90 and the second outlet plate 3142. The provision of the thermal insulation layer 70 provides an anti-condensation effect and can prevent the occurrence of dangerous electric control safety accidents.

[0065] As shown in FIGS. 1 and 2, in some embodiments, the electrical control component 90 includes a protective housing 91 and an electrical element 92. The protective housing 91 includes a box body 911 and a box cover 912. The box body 911 and the box cover 912 are connected to define a sealed fire chamber. The electrical element 92 is located within the fire chamber. This configuration improves the protection capability of the electrical control component 90, prevents the electrical element 92 from malfunctioning and catching fire, and improves the safety factor of the wall-mounted air conditioner 1. Furthermore, the electrical control component 90 can be removed independently, greatly increasing the convenience of testing and repair.

[0066] The electrical element 92 includes a main board 921 and components 922. The main board 921 is parallel to the bottom plate 913 of the box body 911 and has a gap therebetween, and the components 922 are attached to a surface of the main board 913 that faces away from the bottom plate 913. Optionally, the gap between the main board 921 and the bottom plate 913 is 4 mm-15 mm.

[0067] Furthermore, to fit into the mounting space 50, as shown in Figures 1 and 2, the bottom plate 913 of the box body 911 is tilted so that the lower end of the bottom plate 913 is positioned behind the upper end of the bottom plate 913. This configuration makes the structure of the wall-mounted air conditioner 1 more rational. Here, there is a certain angle θ5 between the bottom plate 913 and the vertical direction, and the angle θ5 is between 0 and 90 degrees. A preferred value for θ5 is between 30 and 60 degrees, which allows the mounting of the electrical control component 90 to be more compatible with the angle of the front plate 111 and the shape of the mounting space 50, making the structure of the wall-mounted air conditioner 1 more rational.

[0068] 1 and 2, the width of the lower part of the fire chamber of the protective housing 91 is greater than the width of the upper part. Furthermore, the components 922 include a first set of components and a second set of components. Here, the height of the first set of components is greater than a predetermined value, the height of the second set of components is equal to or less than a predetermined value, and the positions of the second set of components are higher than the positions of the first set of components. That is, the components 922 include some components 922 (the first set of components) that are relatively tall and some components 922 (the second set of components) that are relatively short. In some embodiments, the electrical control component 90 is configured such that the first set of components, which are relatively tall, are mounted below the second set of components, which are relatively short, thereby making the structure of the electrical control component 90 more rational.

[0069] In addition, to further improve the efficiency of inspecting the electrical control components, an inspection hatch is provided on the lower plate portion 1112 of the front plate 111, and the inspection hatch is covered with an inspection cover that is detachably connected to the front plate 111. When it is necessary to inspect the electrical control components 90, the inspection cover is removed from the front plate 111 to expose the inspection hatch, and an inspector can inspect the electrical control components 90 through the inspection hatch, eliminating the need to remove the entire front plate 111 and making the inspection process more convenient and quick.

[0070] In some embodiments, a water tub 60 with its opening facing upward is provided on the rear surface of the first suction plate 3131 and / or the first blow-out plate 3141, where the water tub 60 is provided at an angle and communicates with the water receiving groove 3134. The water tub 60 is used to collect condensed water formed on the rear surface of the first suction plate 3131 and / or the first blow-out plate 3141. The water in the water tub 60 collects in the water receiving groove 3134 and is then discharged together. "The water tub 60 is provided at an angle" means that the water tub 60 is provided at an angle in its longitudinal direction.

[0071] 1 and 2, the water tank 60 is provided on the rear surface of the first wall, and further, in order to better receive condensed water, the water tank 60 is provided at the rearmost part of the rear surface of the first wall.

[0072] As an example, the water tub 60 is disposed at an angle extending in the longitudinal direction of the wall-mounted air conditioner 1, and the water receiving groove 3134 is similarly disposed at an angle extending in the longitudinal direction of the wall-mounted air conditioner 1, with the inclination direction of the water receiving groove 3134 being the same as the inclination direction of the water tub 60. The longitudinal direction of the wall-mounted air conditioner 1 may coincide with the longitudinal direction of the air duct 30. The longitudinal direction of the air duct 30 is indicated by arrow C in Figure 3. The lower end of the water tub 60 is connected to the lower end of the water receiving groove 3134 so that water in the water tub 60 collects in the water receiving groove 3134, and the lower end of the water receiving groove 3134 communicates with a drain outlet provided in the wall-mounted air conditioner 1 so that water in the water tub 60 and the water receiving groove 3134 is discharged from the drain outlet.

[0073] 1 and 2, the first blowing plate 3141 includes a first flat plate portion 3144 adjacent to the blowing outlet 312, and the second blowing plate 3142 includes a second flat plate portion 3145 adjacent to the blowing outlet 312. The projected inner surfaces of the first flat plate portion 3144 and the second flat plate portion 3145 are both straight lines.

[0074] As shown in FIGS. 1 and 2, in a vertical plane perpendicular to the longitudinal direction of the air duct 30, the first angle θ1 between the second flat plate portion 3145 and the center line of the blow-out segment 314 is greater than 0 degrees and equal to or less than 30 degrees.

[0075] If the air flow rate in the outlet passage 3143 (the amount of air discharged from the outlet passage 3143) can be ensured, then by reducing the space occupied by the outlet passage 3143, sufficient installation space will be available in the installation space 50, and components (electrical control components 90) that would normally be installed on the longitudinal sides of the air duct 30 (for example, the left and / or right sides) can be installed within the installation space 50. This effectively reduces the length of the wall-mounted air conditioner 1, further reducing the difficulty of installing the wall-mounted air conditioner 1 and the space required for installation. The left-right direction is indicated by arrow E in Figure 3.

[0076] Alternatively, the first angle θ1 is 1 degree or more and 25 degrees or less. Alternatively, the first angle θ1 is 2 degrees or more and 20 degrees or less. Alternatively, the first angle θ1 is 3 degrees or more and 10 degrees or less. Not only is the air flow rate in the outlet passage 3143 further improved, but the volume of the mounting space 50 is increased, further improving the heating and cooling effect of the wall-mounted air conditioner 1. This allows the length of the wall-mounted air conditioner 1 to be further reduced, and the difficulty of mounting the wall-mounted air conditioner 1 and the space required for mounting can be further reduced.

[0077] Optionally, the first angle θ1 may be, for example, but not limited to, 1 degree, 2 degrees, 3 degrees, 4 degrees, 5 degrees, 6 degrees, 7 degrees, 8 degrees, 9 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, or 30 degrees.

[0078] The second angle θ2 between the first flat plate portion 3144 and the second flat plate portion 3145 is equal to or greater than 5 degrees and equal to or less than 45 degrees. If the air flow rate in the outlet passage 3143 (the amount of air discharged from the outlet passage 3143) can be ensured, then by reducing the space occupied by the outlet passage 314, there is sufficient installation space in the installation space 50, and components (electrical control components 90) that are originally installed on the longitudinal sides of the air duct 30 (for example, the left side and / or right side) can be installed in the installation space 50. This effectively reduces the length of the wall-mounted air conditioner 1, further reducing the difficulty of installing the wall-mounted air conditioner 1 and the space required for installation.

[0079] Alternatively, the second angle θ2 is greater than or equal to 10 degrees and less than or equal to 40 degrees. Alternatively, the second angle θ2 is greater than or equal to 10 degrees and less than or equal to 30 degrees. Alternatively, the second angle θ2 is greater than or equal to 10 degrees and less than or equal to 20 degrees. Not only is the air flow rate in the outlet passage 3143 further improved, but the volume of the mounting space 50 is increased, further improving the heating and cooling effect of the wall-mounted air conditioner 1. This allows the length of the wall-mounted air conditioner 1 to be further reduced, and the difficulty of mounting the wall-mounted air conditioner 1 and the space required for mounting the wall-mounted air conditioner 1 to be further reduced.

[0080] Optionally, the second angle θ2 may be, for example, but not limited to, 5 degrees, 10 degrees, 11 degrees, 12 degrees, 13 degrees, 14 degrees, 15 degrees, 16 degrees, 17 degrees, 18 degrees, 19 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, or 45 degrees.

[0081] 1 and 2, in a vertical plane perpendicular to the longitudinal direction of air duct 30, a third angle θ3 between center line L1 of suction segment 313 and center line L2 of outlet segment 314 is 10 degrees or more and 85 degrees or less. By avoiding large changes in the flow direction of air in air duct 30, the air flow resistance is reduced and the air flows gently in air duct 30, further improving the heating and cooling effect of wall-mounted air conditioner 1.

[0082] Alternatively, the third angle θ3 is between 20 degrees and 80 degrees. Alternatively, the third angle θ3 is between 40 degrees and 75 degrees. Alternatively, the third angle θ3 is between 60 degrees and 75 degrees. Alternatively, the third angle θ3 is between 70 degrees and 75 degrees. This allows the air to flow gently within the air duct 30, further improving the heating and cooling effect of the wall-mounted air conditioner 1.

[0083] Optionally, the third angle θ3 may be, for example, but not limited to, 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, 71 degrees, 72 degrees, 73 degrees, 74 degrees, 75 degrees, 76 degrees, 77 degrees, 78 degrees, 79 degrees, 80 degrees, or 85 degrees.

[0084] 1 and 2, in a vertical plane perpendicular to the longitudinal direction of air duct 30, a fourth angle θ4 between center line L2 of air outlet segment 314 and the vertically upward direction is equal to or greater than 120 degrees and equal to or less than 155 degrees. Air coming out of air outlet passage 3143 flows downward and forward, meaning that wall-mounted air conditioner 1 can discharge cool air (hot air) downward and forward, further improving the cooling and heating effect of wall-mounted air conditioner 1. The vertically upward direction is indicated by the upward arrow of arrow B in FIG. 1.

[0085] Alternatively, the fourth angle θ4 is between 130 degrees and 150 degrees, or between 140 degrees and 145 degrees. This further optimizes the flow direction of the cool air (hot air) discharged from the wall-mounted air conditioner 1, thereby improving the cooling and heating effect of the wall-mounted air conditioner 1.

[0086] Optionally, the fourth angle θ4 may be, for example, but not limited to, 120 degrees, 125 degrees, 130 degrees, 135 degrees, 140 degrees, 141 degrees, 142 degrees, 143 degrees, 144 degrees, 145 degrees, 150 degrees, or 155 degrees.

[0087] As described above, the wall-mounted air conditioner 1 provided according to the embodiment of the present invention has an installation space 50 located at the front and bottom of the interior space of the casing 10, and the electrical control components 90 are installed within this installation space 50. Compared to conventional wall-mounted air conditioners, in which the electrical control components are installed on the longitudinal sides of the air conditioner body, the installation of the electrical control components 90 in the embodiment of the present invention does not occupy space in the longitudinal direction of the air conditioner body. Therefore, for the same width and height, the wall-mounted air conditioner 1 provided according to the embodiment of the present invention has a shorter body length and a more compact structure. Maintaining the length of the air conditioner body allows for reduced noise.

[0088] Furthermore, the mounting space is located behind the front plate of the casing, so that when users wire, assemble / remove, test or repair electrical control components, they do not need to remove the entire casing, but only the front plate, which greatly increases the convenience of testing and repair and improves operational comfort.
