Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioner. Background Art

[0002] At present, the housing of a wall-mounted air conditioner is provided with a front air outlet, and the wall-mounted air conditioner usually adopts a V-shaped evaporator to perform heat exchange on the airflow entering the wall-mounted air conditioner, and blows the airflow out from the front air outlet through the cross-flow fan blades. However, due to structural limitations, the volume of the V-shaped evaporator in the existing wall-mounted air conditioner is generally not too large, and the airflow thrown to the two ends of the V-shaped evaporator by the cross-flow fan blades cannot or partially perform heat exchange with the V-shaped evaporator, resulting in low heat exchange efficiency of the wall-mounted air conditioner. Summary of the invention

[0003] The problem solved by the invention is how to improve the heat exchange efficiency of a wall-mounted air conditioner.

[0004] To solve the above problems, the present invention provides an air conditioner, comprising a shell, a U-shaped heat exchanger and a centrifugal fan blade assembly arranged in the shell; a first air outlet is provided at one end of the shell in the width direction; the U-shaped heat exchanger forms an accommodating cavity, the centrifugal fan blade assembly is arranged in the accommodating cavity, and the opening of the U-shaped heat exchanger is facing away from the side of the shell where the first air outlet is provided.

[0005] In this way, a U-shaped heat exchanger is provided to increase the volume of the heat exchanger in the air conditioner, thereby increasing the heat exchange area and improving the heat exchange efficiency; at the same time, the centrifugal fan blade assembly is arranged in the accommodating cavity surrounded by the U-shaped heat exchanger to increase the amount of wind blown out by the centrifugal fan blade assembly to the U-shaped heat exchanger, thereby further improving the heat exchange effect of the air conditioner.

[0006] Optionally, the U-shaped heat exchanger includes a first bending section, a second bending section and a third bending section that are integrally formed and connected in sequence, the first air outlet corresponds to the second bending section, and a side air outlet is provided at the end of the shell in the length direction, and the side air outlet corresponds to the first bending section and / or the third bending section.

[0007] In this way, by setting the first air outlet and the side air outlet, the side end of the air conditioner can also discharge air. On the one hand, multi-directional and wide-angle air supply is realized, enriching the air outlet mode of the air conditioner, making the air outlet direction and angle of the air conditioner wider, and the air blown out by the air conditioner forms a circulating convection in the room, which improves the comfort of the air conditioner when used; on the other hand, the air outlet area of ​​the air conditioner is increased, so that the air conditioner is suitable for providing a larger air outlet to improve the heating or cooling effect of the air conditioner, thereby improving the user experience; and, setting the U-shaped heat exchanger as an integrated structure can not only reduce the number of parts and components, reduce the difficulty of disassembly and assembly of the U-shaped heat exchanger, but also enhance the structural strength of the U-shaped heat exchanger; in addition, the second bending section corresponds to the first air outlet, and the first bending section and / or the third bending section corresponds to the side air outlet, so as to ensure that the wind after heat exchange through the first bending section and / or the third bending section can be smoothly blown out from the side air outlet, and the wind after heat exchange through the second bending section can be smoothly blown out from the first air outlet.

[0008] Optionally, it also includes a guide mechanism arranged at the intersection of the wind channel between the side air outlet and the first air outlet, the guide mechanism includes a wind shield component and a guide component, the wind shield component is suitable for opening or closing the side air outlet, and the guide component is suitable for guiding the airflow flowing to the guide component to be blown out from the side air outlet and / or the first air outlet when the wind shield component opens the side air outlet.

[0009] In this way, the wind shield component of the guide mechanism is used to control the opening or closing of the side air outlet, so as to realize active air supply from the side air outlet, and then realize independent air supply, so that the multi-directional air supply of the air conditioner is selective and controllable, thereby diversifying the functions of the air conditioner, and making it convenient for users to choose one-way air outlet or multi-directional air supply according to actual needs, thereby improving user satisfaction; moreover, the guide mechanism is arranged at the intersection of the wind duct between the first air outlet and the side air outlet, instead of being arranged at the plane where the side air outlet is located, so that the guide mechanism can divert the airflow while realizing the function of controlling the opening or closing of the side air outlet, so that the airflow can be better blown out from the first air outlet and / or the side air outlet, thereby improving the air output and air outlet effect of the air conditioner.

[0010] Optionally, the wind shield assembly includes a wind shield and a motor, and the motor drives the wind shield to switch between a closed position and an open position; when the wind shield is in the closed position, the wind shield is suitable for shielding the side air outlet; when the wind shield is in the open position, the wind shield is suitable for opening the side air outlet to connect the side air outlet with the external space of the air conditioner.

[0011] In this way, by setting a wind shield and a motor to control the opening or closing of the side air outlet, not only is the structure simple and easy to implement, but it also improves the convenience of opening and closing the side air outlet of the air conditioner; at the same time, it makes the side air outlet of the air conditioner selective and controllable, enriching the air outlet mode of the air conditioner.

[0012] Optionally, the wind shield includes a connected rack portion and a wind shield portion, a gear is provided on the output shaft of the motor, and a tooth structure meshing with the gear is provided on the rack portion, and the motor drives the wind shield to perform lifting and lowering movements between the closed position and the open position.

[0013] In this way, the tooth structure on the rack part is used to mesh with the gear to achieve the lifting movement of the windshield between the closed position and the open position, which is not only easy to control but also has a simple structure and is easy to manufacture.

[0014] Optionally, the guide assembly includes a first guide plate; one end of the first guide plate is in contact with one end of the wind shield away from the motor, and the other end extends toward the side air outlet and is connected to the shell; the first guide plate is suitable for guiding the airflow flowing toward the first guide plate to be blown out from the side air outlet when the wind shield is in the open position.

[0015] In this way, the first guide plate is set to ensure that the air can be discharged smoothly when the air conditioner is discharged from the side; one end of the first guide plate is in contact with the wind shield to guide and limit the wind shield to prevent the wind shield from shaking during the lifting process, and to ensure that the wind shield is stably lifted and lowered along the edge of the first guide plate; the other end of the first guide plate is connected to the shell to ensure the stability of the first guide plate when it is fixed in the shell, and at the same time, to prevent the airflow flowing to the side air outlet when the air conditioner is discharged from the side from leaking from between the first guide plate and the shell.

[0016] Optionally, the vertical height of the first guide plate is greater than the movement stroke of the wind shield plate.

[0017] In this way, it is ensured that the wind shield can always be in contact with the first guide plate during the lifting process, and the wind shield is prevented from deflecting or shaking after being separated from the first guide plate, thereby ensuring stable lifting of the wind shield.

[0018] Optionally, the guide assembly also includes a second guide plate connected to the first guide plate; one end of the second guide plate is connected to one end of the first guide plate away from the shell, and the other end extends toward the first air outlet and is connected to the shell; the second guide plate is suitable for guiding the airflow flowing to the second guide plate to be blown out from the first air outlet.

[0019] In this way, when the wind shield is in the open position, in the airflow flowing through the guide assembly, a part of the airflow flows to the first guide plate and is blown out from the side air outlet along the first guide plate toward the side air outlet, and the other part of the airflow flows to the second guide plate and flows along the second guide plate to the first air outlet and is blown out from the first air outlet, so as to avoid the airflow directly colliding with the inner wall of the shell and generating loud noise; when the wind shield is in the closed position, the airflow flowing through the guide assembly flows along the wind shield and the second guide plate to the first air outlet and is blown out from the first air outlet, that is, the wind shield and the second guide plate guide the airflow, so as to avoid the airflow directly colliding with the inner wall of the shell and generating loud noise.

[0020] Optionally, both the wind shield and the second air guide plate are arc-shaped plate structures, and the side surfaces of the wind shield and the second air guide plate facing away from the side air outlet are located on the same arc surface.

[0021] In this way, when the wind shield is in the closed position, the airflow will not be blocked by the protrusion when flowing from the wind shield to the second guide plate, so it can be smoothly blown out from the first air outlet through the wind shield and the second guide plate in sequence, effectively reducing the airflow noise.

[0022] Optionally, the first guide plate and the second guide plate form a V-shaped plate structure, and an opening of the V-shaped plate structure faces an end of the shell away from the mounting surface.

[0023] In this way, when the side air outlet is opened, the airflow flowing to the guide assembly is split at the first guide plate and the second guide plate, so that part of the airflow passes through the first guide plate and is blown out from the side air outlet, and the other part of the airflow passes through the second guide plate and is blown out from the first air outlet; and when the first guide plate and the second guide plate form a V-shaped plate structure, the guide assembly as a whole presents a triangular structure, and the structure is more stable.

[0024] Optionally, it also includes an air guiding mechanism arranged at the first air outlet and / or the side air outlet, and the air guiding mechanism is suitable for adjusting the air outlet angle of the first air outlet and / or the side air outlet.

[0029] In this way, the first centrifugal fan blade and the second centrifugal fan blade can be controlled independently. When users located in the air supply area of ​​the first centrifugal fan blade and the second centrifugal fan blade have different requirements for the air outlet speed, users in different areas can select the rotation speed of the centrifugal fan blade in their corresponding area according to actual needs to reduce or increase the air outlet speed and air volume of the centrifugal fan blade, so that the air conditioner can adapt to the usage needs of users in different areas; the motors of the two guide mechanisms are arranged in parallel, so that the two guide mechanisms can be controlled independently. At this time, the second air outlet and the third air outlet can be opened or closed at the same time, or the second outlet One of the air outlet and the third air outlet is opened and the other is closed, which makes the multi-directional and wide-area air outlet of the air conditioner selectable and controllable, and is convenient for users to choose to open or close one or two of the second air outlet and the third air outlet according to actual needs, so as to realize the needs of one-way air supply or multi-directional air supply, thereby improving the application scope of the air conditioner; at the same time, the first air guide motor, the second air guide motor and the third air guide motor can be controlled independently, so that the first air guide structure, the second air guide structure and the third air guide structure can be controlled independently, so that users can adjust the air outlet angles at different air outlets according to actual needs.

[0040] Combination Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an air conditioner, comprising a shell 1, a U-shaped heat exchanger 2 and a centrifugal fan blade assembly 3 arranged in the shell 1; a first air outlet 11 is provided at one end of the shell 1 in the width direction; the U-shaped heat exchanger 2 forms an accommodating cavity 24, the centrifugal fan blade assembly 3 is arranged in the accommodating cavity 24, and the opening of the U-shaped heat exchanger 2 is facing away from the side of the shell 1 where the first air outlet 11 is located.

[0041] In this embodiment, a U-shaped heat exchanger 2 is provided to increase the volume of the heat exchanger in the air conditioner, thereby increasing the heat exchange area and improving the heat exchange efficiency; at the same time, the centrifugal fan blade assembly 3 is provided in the accommodating cavity 24 surrounded by the U-shaped heat exchanger 2 to increase the amount of wind blown out by the centrifugal fan blade assembly 3 onto the U-shaped heat exchanger 2, thereby further improving the heat exchange effect of the air conditioner.

[0042] Specifically, the housing 1 of the air conditioner is used to protect and arrange the U-shaped heat exchanger 2 and the centrifugal fan assembly 3 and other components therein. The two ends of the housing 1 in the width direction are the front end and the rear end of the housing 1, respectively. Figure 1 X-axis direction; the front end of the housing 1 (i.e. the housing 1 is located at Figure 1 The first air outlet 11 is provided at the end of the housing 1 in the positive direction of the X axis, so the first air outlet 11 is also the front air outlet of the housing 1, and the opposite end of the housing 1 to which the first air outlet 11 is provided is the rear end of the housing 1, so the opening of the U-shaped heat exchanger 2 faces the rear end of the housing 1. Figure 1 The end opposite to the X-axis in the middle is suitable for being directly connected to the installation surface (such as a wall) or connected through a bracket to install the air conditioner on the wall. By setting the U-shaped heat exchanger 2, the volume of the heat exchanger in the air conditioner is increased, thereby increasing the heat exchange area and improving the heat exchange efficiency; at the same time, by setting the centrifugal fan blade assembly 3 in the accommodating cavity 24 surrounded by the U-shaped heat exchanger 2, the air volume blown by the centrifugal fan blade assembly 3 to the U-shaped heat exchanger 2 is increased, thereby further improving the heat exchange effect of the air conditioner.

[0043] Optionally, combined Figure 2 As shown, the U-shaped heat exchanger 2 is an integrated structure, including a first bending section 21, a second bending section 22 and a third bending section 23 connected in sequence, the first air outlet 11 corresponds to the second bending section 22, and a side air outlet 12 is provided at the end of the shell 1 in the length direction, and the side air outlet 12 corresponds to the first bending section 21 and / or the third bending section 23.

[0044] In this embodiment, the two ends of the shell 1 in the length direction are the left end and the right end of the shell 1, wherein the length direction of the shell 1 refers to Figure 1 Y-axis direction; the left end of the housing 1 (i.e. the housing 1 is located at Figure 1The end opposite to the Y axis in the middle) and / or the right end of the housing 1 (i.e. the housing 1 is located at Figure 1 A side air outlet 12 is provided at one end of the housing 1 in the positive direction of the Y axis. That is to say, the side air outlet 12 can be provided only at the left end of the housing 1, or only at the right end of the housing 1, or at both the left and right ends of the housing 1. On the basis that the first air outlet 11 is provided at the front end of the housing 1, a side air outlet 12 is additionally provided at the left and / or right ends of the housing 1. In this way, by providing the first air outlet 11 and the side air outlet 12, the side end of the air conditioner can also discharge air. On the one hand, multi-directional and wide-angle air supply is realized, enriching the air outlet mode of the air conditioner, making the air outlet direction and angle of the air conditioner wider, and the air blown out by the air conditioner forms a circulating convection in the room, which improves the comfort of the air conditioner when in use; on the other hand, the air outlet area of ​​the air conditioner is increased, so that the air conditioner is suitable for providing a larger air outlet to improve the heating or cooling effect of the air conditioner, thereby improving the user experience. The U-shaped heat exchanger 2 is vertically arranged in the shell 1, and the opening of the U-shaped heat exchanger 2 faces the rear end of the shell 1. The U-shaped heat exchanger 2 is an integrated structure, which is bent to form a first bending section 21, a second bending section 22 and a third bending section 23, and the first bending section 21, the second bending section 22 and the third bending section 23 together form a receiving chamber 24, so as to contain the centrifugal fan blade assembly 3 and other components in the receiving chamber 24, so as to protect the centrifugal fan blade assembly 3 and other components. In this way, setting the U-shaped heat exchanger 2 as an integrated structure can not only reduce the number of parts and components, reduce the difficulty of disassembly and assembly of the U-shaped heat exchanger 2, but also enhance the structural strength of the U-shaped heat exchanger 2. In addition, the second bending section 22 corresponds to the first air outlet 11, and the first bending section 21 and / or the third bending section 23 corresponds to the side air outlet 12, so as to ensure that the wind after heat exchange through the first bending section 21 and / or the third bending section 23 can be blown out smoothly from the side air outlet 12, and the wind after heat exchange through the second bending section 22 can be blown out smoothly from the first air outlet 11.

[0045] Optionally, combined Figure 2 As shown, the centrifugal fan blade assembly 3 includes a first centrifugal fan blade 31 and a second centrifugal fan blade 32 which are arranged at intervals along the length direction of the housing 1; and the first centrifugal fan blade 31 and the second centrifugal fan blade 32 are arranged symmetrically relative to a plane perpendicular to the length direction of the housing 1. In this way, by arranging two centrifugal fan blades, the air output of the centrifugal fan blade assembly 3 can be increased, and the heat exchange effect of the U-shaped heat exchanger 2 can be improved. At the same time, the two centrifugal fan blades are symmetrically arranged to simplify the structure of the centrifugal fan blade assembly 3, which is convenient for production and manufacturing.

[0046] Furthermore, an electrical control box 33 is provided between the first centrifugal fan blade 31 and the second centrifugal fan blade 32, and the first centrifugal fan blade 31 and the second centrifugal fan blade 32 are both electrically connected to the electrical control box 33, the electrical control box 33 is located in the middle position of the shell 1, and the first centrifugal fan blade 31 and the second centrifugal fan blade 32 are symmetrically arranged relative to the electrical control box 33.

[0047] Optionally, the air conditioner also includes a guide mechanism 4 arranged at the intersection of the air duct between the side air outlet 12 and the first air outlet 11, the guide mechanism 4 includes a wind shield component 41 and a guide component 42, the wind shield component 41 is suitable for opening or closing the side air outlet 12, and the guide component 42 is suitable for guiding the airflow flowing to the guide component 42 to be blown out from the side air outlet 12 and / or the first air outlet 11 when the wind shield component 41 opens the side air outlet 12.

[0048] Different customers have different requirements for the air outlet direction of the air conditioner. For example, some customers only need to open the front air outlet (i.e., the first air outlet 11), and the side air outlet 12 of the air conditioner does not need to be opened when in use, while some customers need to open both the front air outlet and the side air outlet 12. Moreover, different customers have different requirements for the installation position of the wall-mounted air conditioner. For example, some customers need to install the left end of the air conditioner close to the left wall, and the air outlet on the left side of the air conditioner does not need to be opened when in use, while some customers need to install the right end of the air conditioner close to the right wall, and the air outlet on the right side of the air conditioner does not need to be opened when in use. However, the side air outlet 12 of the existing wall-mounted air conditioner capable of multi-directional air supply is usually opened or closed together with the front air outlet, that is, when the air conditioner is turned on, the side air outlet 12 is opened together with the front air outlet, and when the air conditioner is turned off, the side air outlet 12 is closed together with the front air outlet. This makes it impossible to choose whether to open the side air outlet 12 of the air conditioner according to actual conditions when the air conditioner is turned on, so it cannot meet the usage requirements of different customers.

[0049] In the present embodiment, the air duct corresponding to the side air outlet 12 (i.e., the air duct connected to the side air outlet 12) intersects with the air duct corresponding to the first air outlet 11 (i.e., the air duct connected to the first air outlet 11), and the air duct fork between the side air outlet 12 and the first air outlet 11 refers to the position where the two air ducts intersect, that is, the air duct fork between the second air outlet 121 (described later) and the first air outlet 11 refers to the intersection of the air duct corresponding to the second air outlet 121 and the air duct corresponding to the first air outlet 11, and the air duct fork between the third air outlet 122 (described later) and the first air outlet 11 refers to the intersection of the air duct corresponding to the third air outlet 122 and the air duct corresponding to the first air outlet 11. By arranging a guide mechanism 4 at the wind passage junction between the first air outlet 11 and the side air outlet 12, and utilizing the wind shielding component 41 of the guide mechanism 4 to control the opening or closing of the side air outlet 12, when the side air outlet 12 of the air conditioner is closed, the air flow in the shell 1 is blown out from the first air outlet 11 only; when the side air outlet 12 of the air conditioner is opened, the air flow in the shell 1 is blown out from the first air outlet 11 and the side air outlet 12 together. In this way, it is convenient for the air flow to be blown out from the side air outlet 12 and the first air outlet 11 under the guiding effect of the guide component 42, so as to realize the active air supply of the side air outlet 12, and then realize the independent air supply, so that the air conditioner The multi-directional air supply of the air conditioner is selective and controllable, thereby diversifying the functions of the air conditioner and making it convenient for users to choose one-way air outlet or multi-directional air supply according to actual needs, thereby improving user satisfaction; moreover, the guide mechanism 4 is arranged at the intersection of the wind duct between the first air outlet 11 and the side air outlet 12, rather than being arranged at the plane where the side air outlet 12 is located, so that the guide mechanism 4 can divert the airflow while controlling the opening or closing of the side air outlet 12, so that the airflow can be better blown out from the first air outlet 11 and / or the side air outlet 12, thereby improving the air output and air output effect of the air conditioner.

[0050] Optionally, combined Figures 3 to 5 As shown, the wind shield assembly 41 includes a wind shield 411 and a motor 412, and the motor 412 drives the wind shield 411 to switch between a closed position and an open position; when the wind shield 411 is in the closed position, the wind shield 411 is suitable for shielding the side air outlet 12; when the wind shield 411 is in the open position, the wind shield 411 is suitable for opening the side air outlet 12 to connect the side air outlet 12 with the external space of the air conditioner.

[0051] In this embodiment, for the wind shield 411 disposed at the wind channel fork between the side air outlet 12 and the first air outlet 11, when the wind shield 411 is in the closed position, the wind shield 411 is suitable for shielding the side air outlet 12 of the air conditioner, that is, the air outlet at the side end of the air conditioner is closed, and the air flow in the housing 1 is blown out from the first air outlet 11; when the wind shield 411 is in the open position, the wind shield 411 is suitable for opening the side air outlet 12 so that the side air outlet 12 is connected to the external space of the air conditioner, that is, the air outlet at the side end of the air conditioner is opened, and the air flow in the housing 1 is blown out from the first air outlet 11 and the side air outlet 12 together. In this way, by setting the wind shield 411 and the motor 412 to control the opening or closing of the side air outlet 12, not only the structure is simple and easy to implement; but also the convenience of opening and closing the side air outlet 12 of the air conditioner is improved; at the same time, the side air outlet of the air conditioner is made selectable and controllable, enriching the air outlet mode of the air conditioner.

[0052] Optionally, combined Figure 6 As shown, the windshield 411 includes a connected rack portion 4111 and a windshield portion 4112, a gear 4121 is provided on the output shaft of the motor 412, and a tooth structure 4113 meshing with the gear 4121 is provided on the rack portion 4111. The motor 412 drives the windshield 411 to move up and down between a closed position and an open position.

[0053] In this embodiment, the rack part 4111 and the windshield part 4112 are preferably formed in one piece, and the gear 4121 is fixed on the output shaft of the motor 412 to drive the rack part 4111 of the windshield 411; specifically, the rack part 4111 is provided with a tooth structure 4113, and the tooth structure 4113 is suitable for meshing with the gear 4121. The motor 412 drives the output shaft to rotate to drive the gear 4121 to rotate synchronously. Under the action of the meshing of the gear 4121 and the tooth structure 4113, the rack part 4111 is driven to move upward to open the side air outlet 12, or the rack part 4111 is driven to move downward to close the side air outlet 12. In this way, the tooth structure 4113 on the rack part 4111 is meshed with the gear 4121 to realize the lifting movement of the windshield 411 between the closed position and the open position, which is not only easy to control, but also has a simple structure and is easy to manufacture.

[0054] Furthermore, since the opening degree of the side air outlet 12 is different when the wind shield 411 is lifted between the closed position and the open position, the wind shield 411 has multiple open positions. In this way, the air outlet area of ​​the air conditioner at the side air outlet 12 can be controlled by adjusting the displacement of the lifting movement of the wind shield 411, thereby controlling the air volume of the side air outlet of the air conditioner, so as to further enrich the air outlet mode of the air conditioner.

[0055] Furthermore, the motor 412 is preferably a stepping motor so as to accurately control the displacement of the lifting movement of the wind shield 411 .

[0056] Furthermore, the wind shield 411 also includes a limiting portion, which is suitable for limiting the lifting and lowering displacement of the wind shield 411 so that the wind shield 411 can stably perform the lifting and lowering movement to open or close the side air outlet 12.

[0057] Optionally, combined Figures 3 to 5 As shown, the guide assembly 42 includes a first guide plate 421; one end of the first guide plate 421 is in contact with one end of the wind shield 411 away from the motor 412, and the other end extends toward the side air outlet 12 and is connected to the shell 1; the first guide plate 421 is suitable for guiding the airflow flowing toward the first guide plate 421 to be blown out from the side air outlet 12 when the wind shield 411 is in the open position.

[0058] In this embodiment, one end of the first guide plate 421 is fitted with the wind shield 411 to guide and limit the wind shield 411, prevent the wind shield 411 from shaking during the lifting process, and ensure that the wind shield 411 is stably lifted and lowered along the edge of the first guide plate 421. The other end of the first guide plate 421 is connected to the shell 1 to ensure the stability of the first guide plate 421 when it is fixed in the shell 1, and at the same time, prevent the airflow flowing to the side air outlet 12 from leaking between the first guide plate 421 and the shell 1 when the air conditioner is discharged from the side. In this way, by setting the first guide plate 421, it is ensured that the air can be discharged smoothly when the air conditioner is discharged from the side.

[0059] Optionally, combined Figure 5 As shown in FIG. 1 , the vertical height of the first guide plate 421 is greater than the movement stroke of the wind deflector 411. The vertical height of the first guide plate 421 refers to the vertical height of the first guide plate 421 at Figure 5 The dimension in the Z-axis direction, the movement stroke of the wind shield 411 refers to the lifting stroke of the wind shield 411, which is also the vertical distance when the wind shield 411 rises from the lowest position (i.e. the position when the lower end of the wind shield 411 is in contact with the shell 1) to the highest position (i.e. the position when the wind shield 411 cannot continue to rise due to structural restrictions); in this way, it is ensured that the wind shield 411 can always be in contact with the first guide plate 421 during the lifting process, preventing the wind shield 411 from deflecting or shaking after it is separated from the first guide plate 421, thereby ensuring the stable lifting and lowering of the wind shield 411.

[0060] Optionally, combined Figures 3 to 5As shown, the guide assembly 42 also includes a second guide plate 422 connected to the first guide plate 421; one end of the second guide plate 422 is connected to an end of the first guide plate 421 away from the shell 1, and the other end extends toward the first air outlet 11 and is connected to the shell 1; the second guide plate 422 is suitable for guiding the airflow flowing to the second guide plate 422 to be blown out from the first air outlet 11.

[0061] In this embodiment, the first guide plate 421 and the second guide plate 422 are located at the junction of the air passage between the first air outlet 11 and the side air outlet 12, and preferably the first guide plate 421 and the second guide plate 422 are integrally formed. When the air conditioner is running, the second guide plate 422 is suitable for guiding the airflow flowing to the second guide plate 422 to be blown out from the first air outlet 11; in this way, when the wind shield 411 is in the open position, in the airflow flowing to the guide mechanism, a part of the airflow flows to the first guide plate 421 and is blown out from the side air outlet 12 along the first guide plate 421 toward the side of the side air outlet 12, and the other part of the airflow flowing to the second guide plate 422 flows along the second guide plate 422 to the first air outlet 11 and is blown out from the first air outlet 11, so as to avoid the airflow directly colliding with the inner wall of the shell 1 and generating a large noise; when the wind shield 411 is in the closed position, the airflow flowing to the guide mechanism flows along the wind shield 411 and the second guide plate 422 to the first air outlet 11 and is blown out from the first air outlet 11, that is, the wind shield 411 and the second guide plate 422 guide the airflow, so as to avoid the airflow directly colliding with the inner wall of the shell 1 and generating a large noise.

[0062] Optionally, combined Figure 3 As shown, the wind shield 411 and the second air guide plate 422 are both arc-shaped plate structures, and the side surfaces of the wind shield 411 and the second air guide plate 422 facing away from the side air outlet 12 are located on the same arc surface. In this embodiment, the side surfaces of the wind shield 411 and the second air guide plate 422 facing away from the side air outlet 12 are both concave arc surfaces, and are located on the same concave arc surface, so that when the wind shield 411 is in the closed position, the airflow will not be hindered by the protrusion when flowing from the wind shield 411 to the second air guide plate 422, so that it can be smoothly blown out from the first air outlet 11 through the wind shield 411 and the second air guide plate 422 in sequence, effectively reducing the airflow noise.

[0063] Optionally, combined Figure 3As shown, the first guide plate 421 and the second guide plate 422 form a V-shaped plate structure, and the opening of the V-shaped plate structure faces the end of the housing 1 away from the mounting surface. In this way, when the side air outlet 12 is opened, the airflow flowing to the guide assembly 42 is split at the first guide plate 421 and the second guide plate 422, so that a part of the airflow passes through the first guide plate 421 and blows out from the side air outlet 12, and the other part of the airflow passes through the second guide plate 422 and blows out from the first air outlet 11; and when the first guide plate 421 and the second guide plate 422 form a V-shaped plate structure, the guide assembly 42 is a triangular structure as a whole, and the structure is more stable.

[0065] Furthermore, combined with Figure 2 As shown, the side air outlet 12 includes a second air outlet 121 and a third air outlet 122 which are respectively arranged at two ends of the shell 1 in the length direction.

[0066] In this embodiment, the left and right ends of the air conditioner are respectively provided with a second air outlet 121 (also the left air outlet of the housing 1) and a third air outlet 122 (also the right air outlet of the housing 1). The first bending section 21, the second bending section 22 and the third bending section 23 of the U-shaped heat exchanger 2 are respectively provided corresponding to the second air outlet 121, the first air outlet 11 and the third air outlet 122 to ensure that the wind after heat exchange through the first bending section 21 can be smoothly blown out from the second air outlet 121, the wind after heat exchange through the second bending section 22 can be smoothly blown out from the first air outlet 11, and the wind after heat exchange through the third bending section 23 can be smoothly blown out from the third air outlet 122.

[0067] Furthermore, a guide mechanism 4 is provided at the wind channel fork between the second air outlet 121 and the first air outlet 11, and at the wind channel fork between the third air outlet 122 and the first air outlet 11. For ease of description, the guide mechanisms 4 provided at the two wind channel forks are respectively referred to as a left guide mechanism and a right guide mechanism, the left guide mechanism controls the second air outlet 121 to be opened or closed, and the right guide mechanism controls the third air outlet 122 to be opened or closed. The motors 412 of the left air guide mechanism and the right air guide mechanism can be arranged in parallel or in series. When the two motors 412 are arranged in series, the left air guide mechanism and the right air guide mechanism are controlled synchronously, and the second air outlet 121 and the third air outlet 122 are opened or closed at the same time; when the two motors 412 are arranged in parallel, the left air guide mechanism and the right air guide mechanism are controlled independently, and the second air outlet 121 and the third air outlet 122 can be opened or closed at the same time, or one of the second air outlet 121 and the third air outlet 122 can be opened and the other closed.

[0068] Furthermore, the air guiding mechanism includes a first air guiding structure, a second air guiding structure 51 and a third air guiding structure 52 which are respectively arranged at the first air outlet 11, the second air outlet 121 and the third air outlet 122.

[0069] In this embodiment, the first air guide motor of the first air guide structure is suitable for driving the first air guide structure to rotate to adjust the air outlet angle of the first air outlet 11 in the up and down direction or the left and right direction; the second air guide motor of the second air guide structure 51 is suitable for driving the second air guide structure 51 to rotate to adjust the air outlet angle of the second air outlet 121 in the up and down direction or the left and right direction; the third air guide motor of the third air guide structure 52 is suitable for driving the third air guide structure 52 to rotate to adjust the air outlet angle of the third air outlet 122 in the up and down direction or the left and right direction.

[0071] In this embodiment, since the rotation of the first centrifugal fan blade 31 and the second centrifugal fan blade 32 is achieved by driving the fan motor, the first centrifugal fan blade 31 and the second centrifugal fan blade 32 are connected in parallel, which means that the fan motor driving the first centrifugal fan blade 31 to rotate and the fan motor driving the second centrifugal fan blade 32 to rotate are arranged in parallel. In this way, the first centrifugal fan blade 31 and the second centrifugal fan blade 32 can be controlled independently. When users in the air supply area of ​​the first centrifugal fan blade 31 and the second centrifugal fan blade 32 have different requirements for the air outlet speed, users in different areas can select the rotation speed of the centrifugal fan blade in their corresponding area according to actual needs to reduce or increase the air outlet speed and air volume of the centrifugal fan blade, so that the air conditioner can adapt to the usage needs of users in different areas. At the same time, the motors 412 of the two air guide mechanisms 4 located at the left and right ends of the air conditioner are preferably arranged in parallel in this embodiment, so that the multi-directional and wide-area air outlet of the air conditioner has the advantages of being selectable and controllable, and it is convenient for users to choose to open or close one or both of the second air outlet 121 and the third air outlet 122 according to actual needs, so as to realize the demand of unidirectional air supply or multi-directional air supply, thereby improving the application scope of the air conditioner. Moreover, the first air guide motor, the second air guide motor and the third air guide motor are arranged in parallel, so that the first air guide motor, the second air guide motor and the third air guide motor can be independently controlled, so that the first air guide structure, the second air guide structure 51 and the third air guide structure 5 can be independently controlled, so that the user can adjust the air outlet angles at different air outlets according to actual needs.
