Description

Technical Field

[0001] This invention belongs to the field of air conditioner technology, specifically relating to an indoor air conditioner unit and an air conditioner. Background Technology

[0002] The connecting rod of the air deflector drive mechanism in the air conditioner is held by bearing pads installed inside the drive box. That is, the bearing pads are clamped on both sides of the connecting rod, ensuring smooth and reliable operation within the connecting rod's stroke. Because two bearing pads are used, located on the top and bottom sides of the connecting rod, the drive box is relatively large in the vertical direction. Due to the limited space in the air conditioner's indoor unit, this structure significantly restricts the layout of the drive box. Furthermore, the large size of the drive box results in lower production efficiency and higher costs. Summary of the Invention

[0003] Therefore, the present invention provides an indoor air conditioner unit and an air conditioner that can reduce the volume of the drive box for driving the air guide plate, thereby reducing the size of the indoor air conditioner unit.

[0004] On one hand, the present invention provides an indoor air conditioner unit, including a housing, an air outlet, and an air guide plate. The inner diameter of the air conditioner also includes a driving device for moving the air guide plate. The driving device includes an arc-shaped component, which is fixedly connected to the air guide plate. The arc-shaped component rotates around a preset center to drive the air guide plate to open or close the air outlet. An arc-shaped groove is provided on the arc-shaped component, which extends along the length of the arc-shaped component. The driving device includes a limiting component, which includes a support component disposed within the arc-shaped groove. The centerline of the bottom of the arc-shaped groove is an arc, and the preset center is the center of the arc.

[0006] In some embodiments, the side plate is provided with a mounting hole, the limiting rod is disposed in the mounting hole, and a vibration damping element is disposed between the outer peripheral surface of the limiting rod and the inner wall of the mounting hole.

[0007] In some embodiments, the outer peripheral surface of the limiting rod is provided with an anti-rotation surface, the mounting hole is provided with a limiting surface opposite to the anti-rotation surface, and the damping member is a spring disposed between the anti-rotation surface and the limiting surface.

[0008] In some embodiments, an arc-shaped groove is provided on each of the left and right sides of the arc-shaped component, and there are at least four sets of limiting components, with two sets on each of the left and right sides of the arc-shaped component and arranged symmetrically; the two sets of limiting components on any side of the arc-shaped component are respectively a first limiting component and a second limiting component, and the first limiting component is disposed between the air guide plate and the second limiting component.

[0010] In some embodiments, the vertical plane passing through the two sets of first limiting components is plane m, and the center of gravity of the air guide plate and the arc-shaped component as a whole is located on the side of plane m away from the second limiting components.

[0011] In some embodiments, the support member includes a support rod and a rolling element sleeved around the outer periphery of the support rod.

[0012] In some embodiments, the driving device includes an arc-shaped rack disposed on the arc-shaped member and a gear meshing with the arc-shaped rack, the arc-shaped rack being disposed on the side of the arc-shaped member facing the center.

[0013] The present invention also provides an air conditioner, including the aforementioned indoor unit.

[0014] The present application has only one support component, which is located in the arc groove of the arc-shaped component of the drive air guide plate (the prior art is located on the upper and lower outer sides of the arc-shaped component, and two bearing pads are provided to support the arc-shaped component, which has a large volume in the vertical direction). It is not necessary to set support structures on both the inner and outer sides of the arc-shaped component, thus reducing the volume of the drive device (volume in the vertical direction).

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0036] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0037] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0038] See also Figure 1-16 As shown, the present invention provides an indoor air conditioner unit, including a housing 1, wherein the housing 1 is provided with an air outlet 101, the air outlet 101 is provided with an air guide plate 2, and the inner diameter of the air conditioner also includes a driving device for driving the air guide plate 2 to move. The driving device includes an arc-shaped component 3, the arc-shaped component 3 is fixedly connected to the air guide plate 2, and the arc-shaped component 3 can rotate around a preset center to drive the air guide plate 2 to open or close the air outlet 101. An arc-shaped groove 301 is provided on the arc-shaped component 3, the arc-shaped groove 301 extends along the length direction of the arc-shaped component 3. The driving device includes a limiting component, the limiting component includes a support member 4 disposed in the arc-shaped groove 301. The center line of the bottom of the arc-shaped groove 301 is an arc, and the preset center is the center of the arc.

[0039] This application uses a support member 4 installed within an arc-shaped groove 301. The centerline of the bottom of the arc-shaped groove 301 is an arc, and its center is a preset center. This ensures that when the arc-shaped component 3 drives the air guide plate 2 to rotate around the preset center, the support member 4 remains within the arc-shaped groove 301 to support the arc-shaped component 3, maintaining its smooth rotation and thus ensuring the smooth operation of the air guide plate 2. Since the support member 4 is installed within the arc-shaped groove 301 of the arc-shaped component 3 driving the air guide plate 2, compared to the prior art where the support structure is clamped on both sides of the connecting rod (the component driving the air guide plate 2), the support member 4 installed within the arc-shaped groove 301 in this application is smaller in size, occupies less space, and consequently, the indoor unit of the air conditioner can also be smaller, improving production efficiency, reducing costs, and occupying less indoor space. In existing technologies, when the support structure is clamped on both sides of the connecting rod, if the gap between the support structure and the connecting rod is small, jamming or jamming can easily occur. If the gap between the support structure and the connecting rod is large, the support effect of the support structure on the connecting rod is weak, and the air guide plate 2 is prone to shaking when it moves. Due to manufacturing tolerances, deformation of the shell 1, etc., it is difficult to maintain a stable gap between the support structure and the connecting rod. In this application, the support member 4 is set in the arc-shaped groove 301, with fewer interoperating parts. The arc-shaped groove 301 is a complete part, and the fitting precision between the support member 4 and the arc-shaped groove 301 is high, which can effectively maintain the support stability of the support member 4 on the arc-shaped part 3, thereby making the air guide plate 2 run smoothly and steadily.

[0040] Furthermore, the arc-shaped component 3 and the air guide plate 2 are fixed together by a pin, and there is no relative displacement between the two.

[0041] Preferred, such as Figure 5 , Figure 14 and Figure 16 As shown, the driving device includes a side plate, the opening of the arc-shaped groove 301 faces the side plate, and the driving device also includes a limiting rod 5 connected to the support rod 401, the limiting rod 5 being connected to the side plate.

[0042] Furthermore, the indoor unit of the air conditioner includes a drive box, and the side panel is one side wall of the drive box.

[0043] The movement of the arc-shaped component 3 is driven by a motor 903, which is housed within a drive box. The drive box is fixed to the side panel of the indoor unit using three screws 904. A limiting rod 5 is installed, connected to the side panel. Since the opening of the arc-shaped groove 301 faces the side panel, the limiting rod 5 needs to be positioned in the left-right direction of the arc-shaped groove 301. This results in a smaller vertical dimension of the indoor unit, improving the user experience.

[0044] Preferred, such as Figure 8 As shown, a mounting hole 6 is provided on the side plate, the limiting rod 5 is disposed in the mounting hole 6, and a vibration damping element is provided between the outer peripheral surface of the limiting rod 5 and the inner wall of the mounting hole 6.

[0045] The limiting rod 5 is installed inside the mounting hole 6, and a vibration damping component is installed between it and the inner wall of the mounting hole 6. This allows the support member 4 to not only provide support when the arc-shaped member 3 rotates, but also to dampen vibrations, reducing the shaking and noise during the movement of the air guide plate 2. Furthermore, when the air guide plate 2 is in operation, the airflow will impact the air guide plate 2, causing it to vibrate and generate noise. By installing the vibration damping component, the vibration and noise generated by the air guide plate 2 when guiding airflow are effectively reduced.

[0046] The limiting rod 5 can move axially along the mounting hole 6 within the mounting hole 6, so that when the indoor unit of the air conditioner is deformed due to temperature, external force, etc., the limiting rod 5 can remain stable within the mounting hole 6, which improves the stability of the limiting component setting, and helps to improve the stability and accuracy of the fit between the support 4 and the arc groove 301, thereby improving the stability and low noise of the air guide plate 2 operation.

[0047] Preferred, such as Figure 6-15 As shown, the outer circumferential surface of the limiting rod 5 is provided with an anti-rotation surface 501, and the mounting hole 6 is provided with a limiting surface 601 opposite to the anti-rotation surface 501. The damping element is a spring 7 disposed between the anti-rotation surface 501 and the limiting surface 601.

[0048] By setting an anti-rotation surface 501 and placing the spring 7 between the anti-rotation surface 501 and the limiting surface 601, on the one hand, the spring 7 can better dampen vibration; on the other hand, the limiting rod 5 does not rotate in the mounting hole 6, avoiding the noise and vibration generated by the rotation of the limiting rod 5, thereby making the air guide plate 2 run stably and with low noise.

[0049] Since the spring 7 is positioned between the anti-rotation surface 501 and the limiting surface 601, the spring 7 can not only dampen the limiting rod 5 in its own axial direction, but also, due to the gap between the anti-rotation surface 501 and the limiting surface 601, the spring 7 can be further compressed. This allows the limiting rod 5 to rotate at a small angle relative to the mounting hole 6 in the circumferential direction. In other words, the spring 7 can exert a force on the limiting rod 5 in the circumferential direction of the mounting hole 6, thus damping and buffering the limiting rod 5 in the circumferential direction. In this way, the arc-shaped part 3 and the air guide plate 2 are further damped.

[0050] Furthermore, the mounting hole 6 is a rectangular hole, and one side of the rectangular hole is the limiting surface 601; the cross-section of the limiting rod 5 is rectangular, and similarly, the surface on the limiting rod 5 opposite to the limiting surface 601 is the turning surface 501; due to the action of the spring 7, the inner wall surface of the mounting hole 6 opposite to the limiting surface 601 fits against one surface on the limiting rod 5; a gap of 0.5-1mm is formed between the other two sets of surfaces; thus, the jamming and shaking of the arc-shaped part 3 during operation are effectively reduced, and the operating noise is reduced.

[0051] Preferred, such as Figure 12-15 As shown, an arc-shaped groove 301 is provided on each of the left and right sides of the arc-shaped component 3. There are at least four sets of limiting components, with two sets on each of the left and right sides of the arc-shaped component 3 and arranged symmetrically. The two sets of limiting components on any side of the arc-shaped component 3 are the first limiting component 801 and the second limiting component 802, respectively. The first limiting component 801 is disposed between the air guide plate 2 and the second limiting component 802.

[0052] By setting at least four sets of limiting components, distributed on the left and right sides of the arc-shaped component 3 (in this application, "left and right" refers to the spatial orientation when facing the indoor unit of the air conditioner, and does not limit the specific structural arrangement), more balanced support for the arc-shaped component 3 is achieved. The first limiting component 801 is set between the second limiting component 802 and the air guide plate 2, so that the first limiting component 801 and the second limiting component 802 are distributed along the circle where the arc-shaped groove 301 is located. On the one hand, the two sets of limiting components provide better support for the movement of the arc-shaped component 3, making the movement of the arc-shaped component 3 stable; on the other hand, the setting of two limiting components does not occupy additional external space compared to the setting of individual limiting components, which is conducive to maintaining the miniaturization of the indoor unit of the air conditioner.

[0053] Furthermore, when the air guide plate 2 completely closes the air outlet 101, the first limiting component 801 is located at the end of the arc groove 301 near the air guide plate 2. When the air guide plate 2 completely opens the air outlet 101, the second limiting component 802 is located at the end of the arc groove 301 away from the air guide plate 2. In this way, the distance between the first limiting component 801 and the second limiting component 802 reaches its maximum. Considering the torque formed by the gravity of the air guide plate 2 itself, the greater the distance between the first limiting component 801 and the second limiting component 802, the better the stability of the support of the two limiting components for the air guide plate 2.

[0054] Preferred, such as Figure 6-10 As shown, the first limiting component 801 includes a limiting rod 5, which is a first limiting rod 5, and a mounting hole 6 for accommodating the first limiting rod 5 is a first mounting hole 6; the second limiting component 802 includes a limiting rod 5, which is a second limiting rod 5, and a mounting hole 6 for accommodating the second limiting rod 5 is a second mounting hole 6; the anti-rotation surface 501 of the first limiting rod 5 faces the center of the circle, and the anti-rotation surface 501 of the second limiting rod 5 faces away from the center of the circle.

[0055] like Figure 6 and Figure 9 As shown, considering the torque generated by the gravity of the air guide plate 2, the air guide plate 2 is downward. The first limiting rod 5, which is closer to the air guide plate 2, is subjected to pressure from the arc groove 301 towards the center, while the second limiting rod 5, which is farther from the air guide plate 2, is subjected to pressure from the arc groove 301 away from the center. Thus, by making the anti-rotation surface 501 of the first limiting rod 5 face the center and the anti-rotation surface 501 of the second limiting rod 5 away from the center, the spring 7 (first spring 7) in the first mounting hole 6 is subjected to the compressive force of the torque generated by the gravity of the air guide plate 2, and the spring 7 (second spring 7) in the second mounting hole 6 is also subjected to the compressive force of the torque generated by the gravity of the air guide plate 2. The clever arrangement of the two springs 7 dampens the vibration of the air guide plate 2, effectively improving the smoothness and noise reduction of the air guide plate 2. It is not necessary to set vibration damping parts around the entire perimeter of the mounting hole 6, which is beneficial to reducing the diameter of the mounting hole 6 and thus reducing the size of the air conditioner indoor unit.

[0056] Preferably, the vertical plane passing through the two sets of first limiting components 801 is plane m, and the center of gravity of the air guide plate 2 and the arc-shaped component 3 as a whole is located on the side of plane m away from the second limiting component 802.

[0057] By positioning the center of gravity of the air guide plate 2 and the arc-shaped component 3 as a whole on the side of plane m away from the second limiting component 802, the force direction of the first limiting component 801 and the second limiting component 802 remains unchanged, which helps to improve the stability of the arc-shaped component 3 and the air guide plate 2 during operation, and correspondingly, also helps to reduce noise.

[0058] Preferred, such as Figure 5 and Figure 16 As shown, the support member 4 includes a support rod 401 and a rolling element 402 sleeved on the outer periphery of the support rod 401.

[0059] The support member 4 includes a support rod 401 and a rolling element 402 sleeved around the outer periphery of the support rod 401. This ensures that when the arc-shaped member 3 rotates relative to the support member 4, rolling friction occurs between the arc-shaped member 3 and the support member 4, which helps reduce the rotational resistance of the arc-shaped member 3 and improves the smoothness and stability of its rotation. The support rod 401 does not protrude beyond the rolling element 402, preventing the support rod 401 from contacting the bottom of the arc-shaped groove 301.

[0060] The rolling element 402 functions as a bearing. The rolling element 402 is in clearance fit with the two side walls of the arc-shaped groove 301 within the groove. Specifically, the rolling element 402 of the first limiting assembly 801 contacts the outer side wall of the arc-shaped groove 301 (of the two side walls of the arc-shaped groove 301, the side wall furthest from the center is the outer side wall, facing the center; the corresponding other side wall is the inner side wall, facing away from the center) and forms a gap of approximately 0.2-0.5 mm with the inner side wall of the arc-shaped groove 301. Similarly, the rolling element 402 of the second limiting assembly 802 forms a gap of approximately 0.2-0.5 mm with the outer side wall of the arc-shaped groove 301 and contacts the inner side wall of the arc-shaped groove 301.

[0061] Preferred, such as Figure 3 , Figure 5 and Figure 6 As shown, the driving device includes an arc-shaped rack 902 disposed on the arc-shaped member 3 and a gear 901 meshing with the arc-shaped rack 902. The arc-shaped rack 902 is disposed on the side of the arc-shaped member 3 facing the center.

[0062] By setting a rack and gear 901, the gear 901 drives the rack to rotate the arc-shaped component 3. The rotation process is smooth. Since the arc-shaped rack 902 is set on the side of the arc-shaped component 3 facing the center, it is equivalent to the gear 901 being wrapped by the arc-shaped component 3, which helps to reduce the size of the drive device. The gear 901 is driven by a hydraulic motor 903.

[0063] The drive box consists of a box body, a drive cover 907, motor 903 fixing screws 904, and motor 903 wiring clips 905. The drive assembly includes the drive box, motor 903, gear 901, arc-shaped component 3 and arc-shaped rack 902 fixed on the arc-shaped component 3, support rod 401, limit rod 5 and spring 7.

[0064] The motor 903 is mounted on the drive box by fixing screws 904. The drive box is equipped with a wiring clip 905 to facilitate the wiring of the motor 903. The motor 903 is connected to the drive gear 901 and drives the drive gear 901 to rotate.

[0065] Furthermore, the arc-shaped component 3 is also disposed within the drive box. The inner side of the drive cover 907 has raised ribs 906, forming an arc-shaped groove between two ribs 906. The arc-shaped component 3 is disposed within this groove, which provides initial positioning. However, in operation, the groove does not limit the arc-shaped component 3. The drive cover 907 also has through holes for assembling the support rod 401, the limiting rod 5, the rolling element 402, and the spring 7.

[0066] The present invention also provides an air conditioner, including the aforementioned indoor unit; when the air conditioner is working, the air guide plate of the indoor unit operates smoothly with low noise, resulting in a good user experience.

[0067] It will be readily understood by those skilled in the art that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0068] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention. The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
