Description

Technical Field

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

[0002] As people's living standards improve, the requirements for the refinement of the appearance and the comfort of air supply of air conditioners are getting higher and higher. The traditional air guide plate of an air conditioner mainly realizes wind diversion by rotating around an axis. Since the rotating shaft is set inside the air conditioner, the rotation angle of the air guide plate is limited, resulting in a small air guide angle. In addition, in order to avoid interference between the casing and the air guide plate, a certain gap is often required at the air outlet to provide rotation space, generally 10mm to 20mm, which makes it easy for dust to enter the air conditioner through the gap, and also reduces the refinement of the air conditioner appearance. An existing push-out air guide mechanism uses a rocker arm to push the air guide plate out of the air outlet, and then uses a motor set at the end of the rocker arm to rotate the air guide plate to change the angle of the air guide plate. However, the motor of this air guide mechanism protrudes from the air outlet, which is not only unsightly, but also the motor wire needs to move around the push rod, which is easy to break during long-term operation and has poor reliability.

[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0039] The present application provides an air guide mechanism for an air conditioner. For example, see Figure 1 , Figure 1 This is a schematic diagram of the structure of the air conditioner provided in the embodiment of the present application. Figure 2 for Figure 1 The air conditioner 10 is shown in a cross-sectional view in a first state. The air conditioner 10 includes an air guide mechanism 100 and a housing 200. The housing 200 is provided with an air outlet 210, and the air guide mechanism 100 is mounted on the housing 200 at the air outlet 210. It should be noted that the air conditioner 10 also includes at least an evaporator, a cross-flow fan, an indoor fan, and an electronic control unit disposed within the housing 200, which will not be described in detail here.

[0040] The air deflector mechanism 100 includes an air deflector 110, a first transmission rod 120, a second transmission rod 130, and a drive assembly 140. The air deflector 110 includes an air deflector body 113, and a first connecting portion 111 and a second connecting portion 112 disposed at opposite ends of the air deflector body 113 in a width direction. The first transmission rod 120 is rotatably connected to the second connecting portion 112, and the second transmission rod 130 is rotatably connected to the first connecting portion 111. The drive assembly 140 is mounted on the housing 200 and includes a first drive device 141 and a second drive device 142. The first drive device 141 drives the first transmission rod 120 to rotate relative to the housing 200, and the second drive device 142 drives the second transmission rod 130 to rotate relative to the housing 200, thereby extending the air deflector body 113 or closing the air outlet 210 of the air conditioner.

[0041] The air outlet 210 is a strip-shaped air outlet, and the air guide plate 110 corresponds to the shape of the air outlet 210. The air guide plate body 113 includes a first surface facing the housing 200, and the first connecting portion 111 and the second connecting portion 112 are protruded from the first surface.

[0042] It can be understood that the driving component 140 drives the first transmission rod 120 to rotate relative to the shell 200 to drive the first connecting part 111 to move, thereby causing one end of the air guide plate body 113 in the width direction to move toward or away from the air outlet 210; and drives the second transmission rod 130 to rotate relative to the shell 200 to drive the first connecting part 111 to move, thereby causing the other end of the air guide plate body 113 in the width direction to move toward or away from the air outlet 210; in this way, by respectively adjusting the positions of the two ends of the air guide plate 110 in the width direction, the air guide angle of the air guide plate 110 can be changed to enable the air conditioner 10 to discharge air in different directions in the room.

[0043] For example, see Figure 2 When the air conditioner 10 is in a first state, such as a shutdown state, the first transmission rod 120 rotates to a first relative position of the shell 200, and the second transmission rod 130 rotates to a second relative position of the shell 200, the first connecting portion 111 and the second connecting portion 112 are both retracted into the shell 200, and the air guide plate body 113 moves to the first position, thereby closing the air outlet 210 of the air conditioner to prevent dust from entering.

[0044] For example, see Figure 3-Figure 4 , Figure 3 for Figure 1 The cross-sectional view of the air conditioner in the second state is shown. Figure 4 for Figure 1The cross-sectional view of the air conditioner 10 in the third state is shown. When the air conditioner 10 is in the second state, such as the heating state, the first transmission rod 120 rotates to the third relative position relative to the housing 200, and the second transmission rod 130 rotates to the fourth relative position relative to the housing 200. The first connecting portion 111 and the second connecting portion 112 extend outside the housing 200, and the air deflector body 113 moves to the second position. The air deflector body 113 extends from the top of the air outlet 210 toward the bottom of the air outlet 210 to guide the air downward, so that the air conditioner 10 can discharge air downward. When the air conditioner 10 is in the third state, such as the cooling state, the first transmission rod 120 rotates to the fifth relative position of the housing 200, and the second transmission rod 130 rotates to the sixth relative position of the housing 200. The first connecting portion 111 and the second connecting portion 112 extend outside the housing 200, and the air deflector body 113 moves to the third position. The air deflector body 113 extends from the bottom of the air outlet 210 toward the top of the air outlet 210 to guide the air diagonally upward, so that the air conditioner 10 can discharge air forward. Because cold air has a high density and hot air has a low density, the air conditioner discharges air upward in the cooling state, and the cold air descends from a high altitude, which can quickly lower the room temperature to achieve a cooling effect. In the heating state, the air conditioner discharges air downward, which can quickly allow the user to feel the increase in the ambient temperature, thereby improving the user experience.

[0045] The air guide mechanism 100 of the air conditioner provided in the embodiment of the present application drives the two ends of the air guide plate body 113 in the width direction via a first transmission rod 120 and a second transmission rod 130, respectively. Furthermore, a drive assembly 140 disposed within the air conditioner housing 200 drives the first transmission rod 120 and the second transmission rod 130 to rotate, thereby coordinating the extension of the air guide plate 110 and the adjustment of the air guide direction. On the one hand, the drive assembly 140 is fixed within the air conditioner housing 200, and does not need to extend out of the air outlet, and the wires do not need to follow the movement, thus being less susceptible to damage and having a longer service life. On the other hand, because the rotation center of the air guide plate 110 is outside the housing 200, there is no need to leave a gap at the air outlet for the air guide plate to rotate, which can improve the refinement of the air conditioner's appearance.

[0046] For further information, see Figure 5 , Figure 5A schematic diagram of the partial structure of the air conditioner provided in an embodiment of the present application. The housing 200 of the air conditioner 10 includes a mounting wall 220, and the mounting wall 220 includes a first portion 221 and a second portion 222, wherein the first portion 221 and the second portion 222 are respectively located on opposite sides of the height direction of the air outlet 210; the first transmission rod 120 is configured to be rotatable relative to the first portion 221, and is used to rotate the second connection portion 112 closer to or away from the air outlet 210; the second transmission rod 130 is configured to be rotatable relative to the second portion 222, and is used to rotate the first connection portion 111 closer to or away from the air outlet 210. It should be noted that connecting the first transmission rod 120 and the second transmission rod 130 to positions on both sides of the air outlet 210 on the housing 200 is conducive to flexible flipping of the air guide plate 110.

[0047] Exemplarily, the first portion 221 is located above the air outlet 210, and the second portion 222 is located below the air outlet 210. The housing 200 further includes a front panel 230 and a bottom plate 240 below. Preferably, the first transmission rod 120 is positioned on the first portion 221 near the panel 230, and the first transmission rod 120 is positioned on the second portion 222 near the bottom plate 240. This increases the distance that the first and second transmission rods 120, 130 can extend from the air outlet 210 during rotation, thereby increasing the air guide range of the air guide plate 110. Furthermore, the first and second transmission rods 120, 130 can be positioned closer to the air outlet 210 to increase the rotation angle and minimize interference with the housing 200.

[0048] In some embodiments, the first transmission rod 120 includes a first link and a second link that are bent and connected, the first link being configured to rotate relative to the housing 200, the second link being rotatably connected to the second connecting portion 112, and the first and second links being sandwiched to form a first notch facing the air guide plate body 113; and / or the second transmission rod 130 includes a third and fourth link that are bent and connected, the third link being configured to rotate relative to the housing 200, the fourth link being rotatably connected to the first connecting portion, and the third and fourth links being sandwiched to form a second notch facing the air guide plate body 113. In this manner, the angular range over which the first and second transmission rods 120 and 130 interfere with the housing 200 during rotation can be reduced, thereby increasing the angular range over which the first and second transmission rods 120 and 130 can rotate, thereby increasing the air guide range of the air guide plate 110.

[0049] In some other embodiments, the first transmission rod 120 and / or the second transmission rod 130 are arc-shaped rods and form a notch facing the air guide plate body 113. In this way, the same effect as the above embodiment can be achieved.

[0050] For example, Figure 3As shown, the first transmission rod 120 includes a first connecting rod 121 and a second connecting rod 122 that are bent and connected. The first connecting rod 121 is configured to rotate relative to the shell 200, and the second connecting rod 122 is rotatably connected to the second connecting portion 112. The first connecting rod 121 and the second connecting rod 122 are clamped to form a first notch facing the air guide plate body 113; the second transmission rod 130 is an arc-shaped rod and forms a notch facing the air guide plate body 113.

[0051] In some embodiments, in order to avoid interference between the first transmission rod 120 and the second transmission rod 130, the first connection part 111 and the second connection part 112 can be staggered in the width direction of the air deflector body 113, so that the first transmission rod 120 and the second transmission rod 130 are staggered in the width direction of the air deflector body 113, and do not affect each other when the two rotate.

[0052] In some embodiments, the first drive device 141 includes a first output shaft (not shown), to which the first transmission rod 120 is fixedly connected. The second drive device 142 includes a second output shaft (not shown), to which the second transmission rod 130 is fixedly connected. The first drive device 141 and the second drive device 142 may be motors or other drive devices.

[0053] It can be understood that the first drive device 141 and the second drive device 142 are mounted on the housing 200, for example, on the mounting wall 220. The extension direction of the first output shaft and the second output shaft is parallel to the length direction of the air deflector body 113, so that the air deflector body 113 is transmitted through the first transmission rod 120 and the second transmission rod 130 to adjust the wind guide angle of the air deflector 110. Preferably, the first transmission rod 120 includes a first connecting end (not shown) suitable for connecting to the first output shaft, and the second transmission rod 130 includes a second connecting end (not shown) suitable for connecting to the second output shaft. The first connecting end and the second connecting end are staggered in the width direction of the air deflector body 113, so that the first transmission rod 120 and the second transmission rod 130 are completely staggered in the width direction of the air deflector body 110, and do not affect each other when the two rotate.

[0054] In some embodiments, see Figure 6 , Figure 6Schematic diagram of the structure of the air guide mechanism provided in an embodiment of the present application. The first connecting portion 111 and the second connecting portion 112 are arranged at one end of the air guide body 113 in the length direction, and the third connecting portion 114 is also provided at the other end of the air guide body 113 in the length direction; the air guide mechanism 100 also includes a third transmission rod 150, which is rotatably connected to the third connecting portion 114 and is configured to rotate relative to the housing 200. Preferably, the third connecting portion 114 and the second connecting portion 112 are symmetrically arranged at both ends of the air guide body 113. It can be understood that transmission rods are provided at both ends of the air guide body 113 for transmission to ensure smooth movement of the air guide body 113.

[0055] In some embodiments, a fourth connection portion may be further provided at the other end of the air deflector body 113 in the longitudinal direction, and the air deflector mechanism 100 may further include a fourth transmission rod rotatably connected to the fourth connection portion and configured to rotate relative to the housing 200. Preferably, the fourth connection portion and the first connection portion 111 are symmetrically disposed at both ends of the air deflector body 113.

[0056] The drive assembly 140 drives the first transmission rod 120, the second transmission rod 130, and the third transmission rod 150 to rotate relative to the housing. Exemplarily, the drive assembly 140 further includes a third drive device 143, which includes a third output shaft, to which the third transmission rod 150 is fixedly connected. Optionally, the housing 200 of the air conditioner 10 includes a first sidewall and a second sidewall that are opposed in the longitudinal direction, with the third drive device 143 mounted on the first sidewall and the first drive device 141 and the second drive device 142 mounted on the second sidewall.

[0057] The air guide mechanism 100 of the air conditioner provided in the embodiment of the present application drives the two ends of the air guide plate body 113 in the width direction via a first transmission rod 120 and a second transmission rod 130, respectively. Furthermore, a drive assembly 140 disposed within the air conditioner housing 200 drives the first transmission rod 120 and the second transmission rod 130 to rotate, thereby coordinating the extension of the air guide plate 110 and the adjustment of the air guide direction. On the one hand, the drive assembly 140 is fixed within the air conditioner housing 200, and does not need to extend out of the air outlet, and the wires do not need to follow the movement, thus being less susceptible to damage and having a longer service life. On the other hand, because the rotation center of the air guide plate 110 is outside the housing 200, there is no need to leave a gap at the air outlet for the air guide plate to rotate, which can improve the refinement of the air conditioner's appearance.

[0058] The embodiment of the present application also provides the above-mentioned air conditioner 10, which can be a wall-mounted air conditioner. The air conditioner 10 has the above-mentioned air guide mechanism 100. The air guide mechanism 100 has a simple structure and is not easy to damage, so that the air conditioner 10 has better quality. In addition, the rotation center of the air guide plate 110 is outside the shell 200, and there is no need to leave a gap at the air outlet 210 of the air conditioner 10 for the air guide plate to rotate, which improves the refinement of the appearance of the air conditioner 10.

[0059] The above is a detailed introduction to the air guide mechanism and air conditioner of the air conditioner provided in the embodiment of the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea; at the same time, for technical personnel in this field, based on the ideas of the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
