Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more specifically, to an air deflector mounting structure and a wall-mounted air conditioner. Background Technology

[0002] Existing wall-mounted air conditioners all have air deflectors, which are used to open and close the air outlets and guide the airflow. However, the pivot of existing air deflectors is often located inside the air conditioner, connected to the air guide plate via a connecting arm. This type of air deflector installation structure has poor stability, and in some cases, the structure cannot meet the user's airflow guidance needs. Summary of the Invention

[0003] The problem addressed in this application is how to improve the stability of the air deflector installation structure and better meet users' air deflection needs.

[0004] To address the aforementioned issues, in a first aspect, this application provides an air deflector mounting structure for use in wall-mounted air conditioners. The air deflector mounting structure includes a middle frame, an air deflector, and a drive mechanism. The middle frame forms an air outlet, and two mutually spaced mating grooves are provided on the front side of the middle frame. The air deflector includes a door panel, and two mutually spaced mating parts are provided on the door panel. The two mating parts are respectively embedded in the two mating grooves and can rotate relative to the mating grooves, and the rotation axes of the two mating parts are collinear. The drive mechanism is located inside the middle frame and is connected to the mating parts for transmission, so as to drive the air deflector to rotate relative to the middle frame to open or close the air outlet.

[0005] In this embodiment, by setting the rotational engagement position of the air guide damper and the middle frame on the front side rather than the inner side of the middle frame, the air guide damper is prevented from extending into the middle frame via a connecting arm to connect with it. This reduces the rotational lever arm, making the air guide damper easier to rotate, and also allows for a wider range of tilt angle adjustment, better meeting the user's needs. Furthermore, by embedding the mating part of the air guide damper into the mating groove and allowing it to rotate relative to the groove, the stability of the air guide damper is improved.

[0006] In an optional embodiment, the inner wall surface of the mating groove is an inner cylindrical surface, and the mating part has an outer cylindrical surface adapted to the mating groove. Since the mating groove and the mating part are in a rotational fit relationship, setting the inner wall surface of the mating groove as an inner cylindrical surface and setting the surface of the mating part as an outer cylindrical surface adapted to the inner wall surface of the mating groove can better achieve smooth rotation of the air guide damper and also ensure the stability of the rotational fit.

[0007] In an optional embodiment, an opening is provided at one end of the mating grooves adjacent to each other, and the orientation of the opening is consistent with the rotation axis of the mating part. The drive mechanism is connected to the mating part through the opening. Optionally, the rotation axis of the output end of the drive mechanism is collinear with the rotation axis of the mating part. Considering that the two mating grooves are spaced apart, the drive mechanism is connected to the mating part through an opening at one end of the two mating grooves adjacent to each other. This method is more convenient for the arrangement of the drive mechanism and can also achieve a concealed installation of the drive mechanism.

[0008] In an optional embodiment, the mating part is cylindrical, with one axial end facing and communicating with the opening. The air guide damper also includes a connector, one end of which is connected to the interior of the mating part, and the other end extends from the end of the mating part and extends into the inner side of the middle frame through the opening to be driven by the drive mechanism. In this embodiment, by setting the mating part to be cylindrical and providing one end of the connector to be connected to the interior of the mating part and the other end to extend into the inner side of the middle frame to be driven by the drive mechanism, the stability of the connection between the mating part and the drive mechanism can be ensured.

[0009] In an optional embodiment, the connector has a pusher portion extending radially along the mating portion. The mating portion is provided with a bayonet, which is a through hole penetrating the inner and outer sides of the mating portion, and the pusher portion extends out from the bayonet. By providing the pusher portion and the bayonet, the assembler can adjust the axial position of the connector in the mating portion by pushing and pulling the pusher portion, thereby connecting or disconnecting the connector from the drive mechanism, thus realizing the installation and removal of the air deflector.

[0010] In an optional embodiment, the connector includes a connecting portion extending axially along the mating portion, extending from a hole at the end of the mating portion, and the cross-section of the connecting portion is non-circular and adapted to the shape of the hole. By setting the cross-section of the connecting portion to be non-circular, the connector and the mating portion can rotate synchronously, and when the drive mechanism drives the connecting portion of the connector to rotate, the air deflector also rotates accordingly.

[0011] In an optional embodiment, the mating part includes a fixing part and a cover. The fixing part is connected to the door panel, and the cover is detachably connected to the fixing part, so that together with the fixing part, they enclose the cavity of the mating part. By setting the mating part as a detachably connected fixing part and cover, the internal cavity of the mating part can be opened, making it easier to install the connector.

[0012] In an optional embodiment, the cover is detachably connected to the fixing part by a snap-fit ​​structure.

[0013] In an optional embodiment, the air deflector is rotatably connected to the upper side of the air outlet. By placing the air deflector on the upper side of the air outlet, the air deflector opens the air outlet by swinging upward and closes the air outlet by swinging downward; moreover, the upward and downward swinging amplitude of the air deflector can significantly adjust the air outlet direction, especially during heating, the free end of the air deflector can swing downward to a lower position, thereby guiding the hot airflow downward to achieve better heating.

[0014] Secondly, this application provides a wall-mounted air conditioner, including the air guide damper installation structure of any of the foregoing embodiments. Attached Figure Description

Detailed Implementation

[0022] In current wall-mounted air conditioners, a rotatable air deflector is often installed on the middle frame to open or close the air outlet and to adjust the airflow direction to some extent. The air deflector disclosed in related technologies extends deep into the air conditioner via a connecting arm and is rotatably connected to the middle frame. This air deflector installation structure has several drawbacks: the lever arm is relatively long, making rotation difficult and resulting in poor overall structural stability; the connecting arm extends into the air conditioner's interior, occupying internal space; and because the rotation axis is too close to the air conditioner's interior, the air deflector's rotation range is limited, and the adjustable angle of the door panel is relatively small, sometimes failing to meet the user's airflow needs.

[0023] To address at least one deficiency of the aforementioned air deflector mounting structures, this application provides an air deflector mounting structure and a wall-mounted air conditioner using this structure. By rotatably connecting the air deflector to the mating groove on the front side of the middle frame, the entire air deflector mounting structure achieves better stability and better meets the user's airflow requirements.

[0024] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, specific embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] Figure 1 This is a schematic diagram of a wall-mounted air conditioner 010 in the air outlet 110 closed state in one embodiment of this application; Figure 2 This is a schematic diagram of a wall-mounted air conditioner 010 in the air outlet 110 open state in one embodiment of this application; Figure 3 This is a schematic diagram of the middle frame 100 of a wall-mounted air conditioner 010 in one embodiment of this application. Figures 1 to 3 As shown, the wall-mounted air conditioner 010 provided in this application embodiment includes a middle frame 100, an air guide damper 200, and a drive mechanism (not shown in the figure). The middle frame 100, the air guide damper 200, and the drive mechanism constitute the air guide damper mounting structure provided in this application embodiment. An air outlet 110 is formed at the lower position of the middle frame 100, and the upper edge of the air outlet 110 extends to the front side of the middle frame 100. The air guide damper 200 and the drive mechanism are disposed inside the middle frame 100. The drive mechanism is used to drive the air guide damper 200 to rotate relative to the middle frame 100 to open or close the air outlet 110. Furthermore, the rotation angle of the air guide damper 200 can adjust the direction of airflow. The drive mechanism can be fixedly connected to the middle frame 100 or fixedly connected to the air conditioner base (not shown in the figure). It should be understood that the wall-mounted air conditioner 010 also includes other necessary components, such as heat exchange components, fan components, etc. In addition, the wall-mounted air conditioner 010 provided in this application embodiment also includes a housing wrapped around the outermost part of the air conditioner, the housing including, Figure 1 and Figure 2 Panel 101 is shown in the image.

[0026] like Figures 1 to 3 As shown, the front ends of the middle frame 100 are provided with two mutually spaced mating grooves 120. The air guide damper 200 includes a door panel 210, on which two mutually spaced mating parts 220 are provided. The two mating parts 220 are respectively embedded in the two mating grooves 120 and can rotate relative to the mating grooves 120, and the rotation axes of the two mating parts 220 are collinear. The drive mechanism is drivenly connected to the mating parts 220 in the mating grooves 120 to drive the air guide damper 200 to rotate relative to the middle frame 100, thereby opening or closing the air outlet 110. In this embodiment, the number of drive mechanisms corresponds to the number of mating parts 220, which is also two; in other optional embodiments, only one drive mechanism can be drivenly connected to one of the mating parts 220 to achieve the rotation of the air guide damper 200.

[0027] In this embodiment, by setting the rotational engagement position between the air guide damper 200 and the middle frame 100 on the front side rather than the inner side of the middle frame 100, the air guide damper 200 can avoid extending into the middle frame 100 through the connecting arm to connect with the middle frame 100. This reduces the rotational lever arm, making the rotation of the air guide damper 200 easier, and also allows for a larger tilt angle adjustment range, better meeting the user's needs. Furthermore, by embedding the mating part 220 of the air guide damper 200 into the mating groove 120 and allowing it to rotate relative to the mating groove 120, the stability of the air guide damper 200 is improved.

[0028] In this embodiment, the air guide damper 200 is rotatably connected to the front side of the middle frame 100 and located above the air outlet 110. By positioning the air guide damper 200 above the air outlet 110, the air guide damper 200 can open the air outlet 110 by swinging upward and close the air outlet 110 by swinging downward. Moreover, the upward and downward swing amplitude of the air guide damper 200 can significantly adjust the air outlet direction. Especially during heating, the free end of the air guide damper 200 can swing downward to a lower position, thereby guiding the hot airflow downward to the air conditioner for better heating.

[0029] In this embodiment, two mating grooves 120 are respectively disposed at the left and right ends of the middle frame 100 in the horizontal direction, and the ends of the two mating grooves 120 that are far apart from each other are open. In other optional embodiments, the mating grooves 120 may also have a certain distance from the two ends of the middle frame 100. In addition, in other embodiments, the air outlet 110 may be disposed at a higher position on the middle frame 100 as needed (relative to this embodiment); the air guide damper 200 may also be rotatably connected to the lower side of the air outlet 110. If the air guide damper 200 is disposed on the lower side of the air outlet 110, the airflow can be guided upward by the rotation of the air guide damper 200, so that the cold air can blow upward under the cooling condition, which optimizes the cooling effect and improves the user experience.

[0030] In this embodiment, the inner wall surface of the mating groove 120 is an inner cylindrical surface, and the mating part 220 has an outer cylindrical surface adapted to the mating groove 120. Since the mating groove 120 and the mating part 220 are in a rotational fit relationship, setting the inner wall surface of the mating groove 120 as an inner cylindrical surface and setting the surface of the mating part 220 as an outer cylindrical surface adapted to the inner wall surface of the mating groove 120 can better achieve smooth rotation of the air guide damper 200 and also ensure the stability of the rotational fit.

[0031] like Figure 3 As shown, each of the mating grooves 120 has an opening 121 at one of its adjacent ends, and the orientation of the opening 121 is aligned with the rotation axis of the mating part 220. The output end of the drive mechanism is connected to the mating part 220 via the opening 121. It should be understood that in this embodiment, the drive mechanism is connected to the mating part 220 via the opening 121, specifically meaning that the drive mechanism or the mating part 220 is connected to the drive mechanism via a component that passes through the opening 121. In this embodiment, the rotation axis of the output end of the drive mechanism is collinear with the rotation axis of the mating part 220, and the output ends of the two drive mechanisms are respectively oriented towards opposite ends. Considering that the two mating grooves 120 are spaced apart at the two ends of the front side of the middle frame 100 in the lateral direction, the drive mechanism is connected to the mating part 220 via the opening 121 at one of its adjacent ends. This method facilitates the arrangement of the drive mechanism and also allows for the concealment of the drive mechanism. In alternative embodiments, if the two mating grooves 120 are not located at the two ends of the middle frame 100, but are spaced apart from the two ends of the middle frame 100, then the output end of the drive mechanism can also be connected to the mating part 220 from the ends of the two mating grooves 120 that are far apart from each other.

[0032] Figure 4 This is a schematic diagram of the air guide damper 200 in one embodiment of this application; Figure 5 This is an exploded view of the air guide damper 200 in one embodiment of this application. Figure 4 and Figure 5As shown in this embodiment, the door panel 210 is a plate with a certain curvature, comprising two opposing long sides and two opposing short sides. The overall size of the door panel 210 is adapted to the air outlet 110. Two mating parts 220 are disposed at both ends of one of the long sides. In this embodiment, the mating part 220 is cylindrical, with one axial end facing the opening 121. The air guide door 200 also includes a connector 230, one end of which is connected to the mating part 220, and the other end extends from the end of the mating part 220 and extends into the inner side of the middle frame 100 through the opening 121 to be connected to the drive mechanism. In this embodiment, by setting the mating part 220 to be cylindrical and setting one end of the connector 230 to be connected to the inside of the mating part 220 and the other end to extend into the inner side of the middle frame 100 to be connected to the drive mechanism, the stability of the connection between the mating part 220 and the drive mechanism can be ensured.

[0033] Figure 6 for Figure 5 A magnified view of a section VI in the middle. (See image below.) Figure 6 As shown, the connector 230 includes a pusher portion 231 extending radially along the mating portion 220 and a connecting portion 232 extending axially. The pusher portion 231 is used to mate with the mating portion 220, and the connecting portion 232 is columnar and can pass through a hole 223 at the end of the mating portion 220 and through the opening 121 to be connected to the drive mechanism inside the middle frame 100. The mating portion 220 is provided with a bayonet 221, which is a through hole penetrating the inner and outer sides of the mating portion 220, and the pusher portion 231 extends out from the bayonet 221. By providing the pusher portion 231 and the bayonet 221, the assembler can adjust the position of the connector 230 in the axial direction of the mating portion 220 by pushing and pulling the pusher portion 231, thereby connecting or disconnecting the connector 230 from the drive mechanism, thus realizing the installation and removal of the air deflector 200. Optionally, the bayonet 221 can be a strip-shaped through hole that extends along the axial direction of the mating part 220, so that the pusher part 231 has sufficient room to move.

[0034] In this embodiment, the cross-section of the connecting portion 232 is non-circular and is adapted to the shape of the hole 223. By setting the cross-section of the connecting portion 232 to be non-circular, the connecting member 230 and the mating portion 220 can rotate synchronously. When the driving mechanism drives the connecting portion 232 of the connecting member 230 to rotate, the air guide damper 200 also rotates accordingly. Specifically, the cross-sections of the connecting portion 232 and the hole 223 can be polygonal or elliptical.

[0035] Furthermore, in this embodiment, the mating part 220 includes a fixing part 222 and a cover 224. The fixing part 222 is connected to the door panel 210 and can be integrally formed with the door panel 210. The cover 224 is detachably connected to the fixing part 222 to form the cavity of the mating part 220 together with the fixing part 222. By setting the mating part 220 as a detachably connected fixing part 222 and cover 224, the internal cavity of the mating part 220 can be opened, making it easier to install the connector 230. Specifically, in this embodiment, the cover 224 forms part of the side wall of the mating part 220 and is generally arc-shaped, with a snap-fit ​​221 provided on the cover 224. In other optional embodiments, the cover 224 can be located at the end of the mating part 220, forming the end plate of the mating part 220; the snap-fit ​​221 can also be provided on the fixing part 222. Optionally, in this embodiment, the two mating parts 220 and the two connectors 230 are symmetrically arranged. The edge of the door panel 210 between the two mating parts 220 should be able to avoid the protrusion between the two mating grooves 120 on the middle frame 100 during the rotation of the air guide door 200.

[0036] In this embodiment, the cover 224 is detachably connected to the fixing part 222 by the snap-fit ​​structure 225 to improve the convenience of loading and unloading.

[0037] In this embodiment, the drive mechanism may optionally include a stepper motor and a transmission assembly, with the stepper motor connected to the connection portion 232 of the connector 230 via the transmission assembly. The specific form of the drive mechanism can be configured with reference to existing drive mechanisms, and will not be elaborated further here.

[0038] In summary, in the air guide damper installation structure provided in this application embodiment, by setting the rotational engagement position between the air guide damper 200 and the middle frame 100 on the front side rather than the inner side of the middle frame 100, the air guide damper 200 can avoid extending into the middle frame 100 through the connecting arm to connect with the middle frame 100. This reduces the rotational lever arm, making the rotation of the air guide damper 200 easier, and also allows for a larger tilt angle adjustment range, better meeting the user's needs. Furthermore, by embedding the mating part 220 of the air guide damper 200 into the mating groove 120 and allowing it to rotate relative to the mating groove 120, the stability of the air guide damper 200 is improved.

[0039] The wall-mounted air conditioner 010 provided in this application embodiment includes the above-mentioned air guide door installation structure, and therefore also has corresponding beneficial effects.

[0040] While this application discloses the above information, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of this application; therefore, the scope of protection of this application shall be determined by the scope defined in the claims.
