Description

Technical Field

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

[0002] With the continuous improvement of people's living standards, air conditioners have become an indispensable household appliance. At present, air conditioners are generally equipped with a rotatable air guide door, which is used to guide the air flow of the air conditioner to achieve the function of adjusting the wind direction. However, the current drive motors are directly connected to the ends of the air guide doors. If the rotation axes of the drive motor and the air guide door are both set in the middle frame, then under the limiting effect of the middle frame, the rotation angle of the air guide door is small, resulting in a small air guide range of the air guide door and a poor user experience; if the rotation axes of the drive motor and the air guide door are both set outside the middle frame, the drive motor is external, which takes up a large space and affects the aesthetics of the air conditioner. Summary of the Invention

[0003] The problem solved by the present invention is how to increase the rotation angle of the air guide door when the drive motor is built-in, expand the air guide range, reduce the occupied space, improve the aesthetics, and enhance the user experience.

[0004] To solve the above problems, the technical solution of the present invention is achieved as follows:

[0005] The present invention provides an air conditioner comprising a middle frame, an air guide door, a drive motor, and a transmission assembly. The middle frame is provided with a contoured surface. The transmission assembly comprises a drive box, a driving gear, and a driven gear. The driving gear and the driven gear are in driving connection and are both rotatably mounted on the drive box. The drive motor is disposed on the inner side of the contoured surface and fixedly mounted on the drive box and connected to the driving gear. The driven gear is disposed on the outer side of the contoured surface and connected to the air guide door. Compared to the prior art, the air conditioner provided by the present invention utilizes a drive motor disposed on the inner side of the contoured surface and a driven gear disposed on the outer side of the contoured surface. Therefore, while the drive motor is internally mounted, the air guide door can have a larger rotation angle, a wider air guide range, a smaller footprint, improved aesthetics, and a better user experience.

[0006] Furthermore, the transmission assembly also includes an intermediate gear, which is disposed between the driving gear and the driven gear and meshes with both the driving gear and the driven gear. The driving gear is disposed on the inner side of the contour surface, and the intermediate gear is disposed through the contour surface. The drive motor can drive the intermediate gear to rotate via the driving gear, thereby driving the driven gear to rotate, and further driving the air guide door to rotate, thereby opening or closing the air outlet.

[0007] Furthermore, the diameter of the driving gear is greater than or equal to the diameter of the intermediate gear, and the diameter of the intermediate gear is equal to the diameter of the driven gear. The driving motor can drive the air guide door to rotate at a higher speed at a lower starting speed, thereby reducing the energy consumption of the driving motor and saving usage costs.

[0008] Furthermore, the middle frame is provided with an internal cavity, and an opening is formed on the contour surface, the opening being connected to the internal cavity, the drive motor is disposed in the internal cavity, and the drive box is disposed through the opening. The internal cavity is used to accommodate the drive motor, thereby achieving internal placement of the drive motor and reducing space occupation.

[0009] Furthermore, the drive motor is provided with an output shaft, and a transmission slot is provided in the middle of the driving gear. The output shaft extends into the transmission slot and cooperates with the transmission slot. The drive motor can drive the driving gear to rotate through the cooperation of the output shaft and the transmission slot, thereby ensuring a stable and reliable transmission process.

[0010] Furthermore, the drive box includes a box body and a box cover, which are detachably connected and together define a receiving cavity. The driving gear and the driven gear are both disposed within the receiving cavity, and the drive motor is fixedly mounted on a side of the box cover away from the box body. The output shaft of the drive motor can pass through the box cover and extend into the receiving cavity, where it engages with a transmission slot of the driving gear to enable the drive motor to drive the driving gear to rotate.

[0011] Furthermore, the air conditioner further comprises a base, which is detachably connected to the middle frame, and the drive box is fixedly mounted on the base to fix the relative position of the drive motor and the base and prevent the drive motor from being displaced relative to the base.

[0012] Furthermore, a clearance groove is formed on the outer surface of the middle frame. The clearance groove has an arc-shaped cross-section. The air guide door is disposed within the clearance groove and is rotatable relative to the clearance groove. The clearance groove allows the air guide door to rotate, thereby preventing interference between the air guide door and the middle frame.

[0013] Furthermore, the air guide door includes an air guide door body, a latch, and a socket. The latch is mounted on the air guide door body and extends into and engages with the socket. The socket is connected to a driven gear. The driven gear can drive the socket to rotate, thereby driving the latch to rotate, and then driving the air guide door body to rotate, thereby achieving the air guide function.

[0014] Furthermore, there are two drive motors and two transmission assemblies, each connected to a transmission assembly. The two transmission assemblies are positioned opposite each other at either end of the air guide door. The two drive motors operate synchronously to drive the air guide door to rotate, ensuring stable and reliable rotation of the air guide door. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] First embodiment

[0026] Please refer to Figure 1 and Figure 2 The embodiment of the present invention provides an air conditioner 100 for adjusting the air outlet direction. It can realize the built-in drive motor 140, reduce the occupied space, improve the aesthetics, and facilitate disassembly and maintenance to avoid interference.

[0027] In this embodiment, the air conditioner 100 is a wall mounted air conditioner. The air conditioner 100 is mounted on a wall and can blow hot air or cold air into the room to achieve a heating or cooling function.

[0028] The air conditioner 100 includes a middle frame 110, a base 120, an air guide door 130, a drive motor 140, a transmission assembly 150, a fan (not shown) and a heat exchanger (not shown). The base 120 is mounted on the wall, and the fan and the heat exchanger are both mounted on the base 120. The middle frame 110 is covered outside the base 120 and is detachably connected to the base 120 to shield and protect the fan and the heat exchanger. The fan is used to generate negative pressure to drive air flow to form an outlet airflow. The heat exchanger is used to exchange heat with the outlet airflow so that the outlet airflow has the function of heating or cooling.

[0029] It should be noted that the middle frame 110 is provided with a contoured surface 114, which extends along the outer contour of the middle frame 110 and is located on the side of the middle frame 110 away from the wall. The drive motor 140 is disposed on the inner side of the contoured surface 114, and the air guide door 130 is disposed on the outer side of the contoured surface 114. The drive motor 140 can drive the air guide door 130 to rotate through the transmission assembly 150. This allows the drive motor 140 to be internally mounted while ensuring the air guide door 130's driving function, reducing space usage and improving aesthetics.

[0030] Please refer to Figure 3 and Figure 4 The transmission assembly 150 includes a drive box 151, a driving gear 152 and a driven gear 153. The driving gear 152 is connected to the driven gear 153 in a transmission manner and both are rotatably mounted on the drive box 151. The driving gear 152 can drive the driven gear 153 to rotate. The drive motor 140 is fixedly mounted on the drive box 151, and the drive box 151 is fixedly mounted on the base 120 to fix the relative position of the drive motor 140 and the base 120 to prevent the drive motor 140 from being displaced relative to the base 120. The drive motor 140 is connected to the driving gear 152, and the drive motor 140 can drive the driving gear 152 to rotate. The driven gear 153 is arranged on the outside of the contour surface 114 and is connected to the air guide door 130. The driven gear 153 can drive the air guide door 130 to rotate relative to the middle frame 110 to open or close the air outlet 113. In this way, the drive motor 140 arranged on the inner side of the contour surface 114 can output power outward through the transmission assembly 150 to rotate the air guide door 130 outside the contour surface 114, thereby realizing the internalization of the drive motor 140 and ensuring the transmission effect.

[0031] It is worth noting that the transmission assembly 150 also includes an intermediate gear 154, which is rotatably mounted on the drive box 151 and disposed between the driving gear 152 and the driven gear 153. The intermediate gear 154 meshes with both the driving gear 152 and the driven gear 153, and the driving gear 152 can drive the driven gear 153 to rotate via the intermediate gear 154. Specifically, the driving gear 152 is disposed on the inner side of the contoured surface 114, the intermediate gear 154 is disposed through the contoured surface 114, and the driven gear 153 is disposed within the air guide door 130. The drive motor 140 can drive the intermediate gear 154 to rotate via the driving gear 152, thereby driving the driven gear 153 to rotate, and further driving the air guide door 130 to rotate.

[0032] In this embodiment, the diameter of the driving gear 152 is larger than that of the intermediate gear 154, and the diameter of the intermediate gear 154 is equal to that of the driven gear 153. The larger the diameter of the driving gear 152, the greater the distance between the axis of the driving gear 152 and the contoured surface 114. The drive motor 140 is connected to the axis of the driving gear 152. The greater the distance between the axis of the driving gear 152 and the contoured surface 114, the larger the area on the drive box 151 for mounting the drive motor 140. This effectively prevents interference between the drive motor 140 and the contoured surface 114, facilitating disassembly and maintenance of the drive motor 140.

[0033] Specifically, in the process of the driving gear 152 driving the driven gear 153 to rotate through the intermediate gear 154, the speed increases and the torque decreases, that is, the driving motor 140 can drive the air guide door 130 to rotate at a higher speed at a lower starting speed, thereby reducing the energy consumption of the driving motor 140 and saving usage costs.

[0034] In this embodiment, the drive motor 140 is provided with an output shaft 141. A transmission slot 1521 is defined in the middle of the driving gear 152. The output shaft 141 extends into the transmission slot 1521 and engages with the transmission slot 1521. The drive motor 140 is able to drive the driving gear 152 to rotate through the engagement of the output shaft 141 and the transmission slot 1521, thereby ensuring a stable and reliable transmission process. Specifically, the output shaft 141 is provided with a limiting surface 142, and the transmission slot 1521 is provided with a rotation-stopping wall 1522. When the output shaft 141 engages with the transmission slot 1521, the limiting surface 142 and the rotation-stopping wall 1522 are abutted against each other, thereby preventing the output shaft 141 from slipping relative to the transmission slot 1521 and improving transmission stability.

[0035] The drive box 151 includes a box body 1511 and a box cover 1512. The box body 1511 and the box cover 1512 are detachably connected and together form a receiving cavity (not shown). The driving gear 152, the intermediate gear 154 and the driven gear 153 are all arranged in the receiving cavity and are all able to rotate in the receiving cavity. The drive motor 140 is fixedly mounted on the side of the box cover 1512 away from the box body 1511. The output shaft 141 of the drive motor 140 can pass through the box cover 1512 and extend into the receiving cavity, and cooperate with the transmission groove 1521 of the driving gear 152 to realize the function of the drive motor 140 driving the driving gear 152 to rotate.

[0036] Please refer to Figure 5 and Figure 6 In this embodiment, the middle frame 110 is provided with an internal cavity 112. An opening 111 is formed on the contour surface 114. The opening 111 is connected to the internal cavity 112. The drive motor 140 is disposed in the internal cavity 112, and the drive box 151 is disposed through the opening 111. The internal cavity 112 is used to accommodate the drive motor 140, thereby realizing the internal placement of the drive motor 140 and reducing the occupied space.

[0037] It should be noted that the middle frame 110 is provided with an air outlet 113, which is arranged below the opening 111. The driving motor 140 can drive the air guide door 130 to rotate relative to the middle frame 110 through the transmission assembly 150, so that the air guide door 130 opens or closes the air outlet 113, thereby realizing the function of adjusting the blowing direction of the outlet air flow.

[0038] In this embodiment, there are two drive motors 140 and two transmission assemblies 150. Each drive motor 140 is connected to a transmission assembly 150, and the two transmission assemblies 150 are disposed opposite each other at the ends of the air guide door 130. The two drive motors 140 operate synchronously to drive the air guide door 130 to rotate, ensuring stable and reliable rotation of the air guide door 130.

[0039] It is noteworthy that the outer surface of the middle frame 110 is provided with a clearance groove 115, which has an arcuate cross-section. The air guide door 130 is partially disposed within the clearance groove 115 and is rotatable relative to the clearance groove 115. The clearance groove 115 allows the air guide door 130 to move freely, thereby facilitating rotation of the air guide door 130 and preventing interference between the air guide door 130 and the middle frame 110. Specifically, the bottom wall of the clearance groove 115 is formed as a contoured surface 114. An opening 111 is defined in the bottom wall of the clearance groove 115. The drive box 151 can pass through the opening 111 and extend into the air guide door 130, facilitating connection between the driven gear 153 and the air guide door 130.

[0040] Specifically, the air outlet 113 is arranged below the give way slot 115. When the air guide door 130 rotates downward, the air outlet 113 can be closed. When the air guide door 130 rotates upward, the air outlet 113 can be opened. The outlet air flow can be blown outward under the guiding action of the air guide door 130 to adjust the outlet direction.

[0041] The air guide door 130 includes a door body (not shown), a latch (not shown), and a socket (not shown). The latch is mounted on the door body and extends into and engages with the socket, which is connected to a driven gear 153. The driven gear 153 drives the socket to rotate, thereby driving the latch, which in turn drives the air guide door body to rotate, achieving the air guide function.

[0042] In this embodiment, the air guide door body is provided with a rotating shaft cylinder, which can rotate along the axis of the rotating shaft cylinder. A latch is installed in the rotating shaft cylinder to fix the relative position of the latch and the rotating shaft cylinder, preventing the latch from moving relative to the rotating shaft cylinder. The socket and the driven gear 153 are arranged coaxially and fixedly connected. The latch extends into the socket and engages with the socket. The drive motor 140 can drive the driven gear 153 to rotate via the driving gear 152 and the intermediate gear 154, thereby driving the socket to rotate. In turn, the entire air guide door 130 is driven by the latch and the rotating shaft cylinder to adjust the air outlet direction.

[0043] In the air conditioner 100 according to the embodiment of the present invention, the middle frame 110 is provided with a contoured surface 114. The transmission assembly 150 includes a drive box 151, a driving gear 152, and a driven gear 153. The driving gear 152 and the driven gear 153 are in driving connection and are both rotatably mounted on the drive box 151. The drive motor 140 is disposed on the inner side of the contoured surface 114 and fixedly mounted on the drive box 151 and connected to the driving gear 152. The driven gear 153 is disposed on the outer side of the contoured surface 114 and connected to the air guide door 130. Compared with the prior art, the air conditioner 100 provided by the present invention utilizes the drive motor 140 disposed on the inner side of the contoured surface 114 and the driven gear 153 disposed on the outer side of the contoured surface 114. Therefore, while the drive motor 140 is internally mounted, the rotation angle of the air guide door 130 can be increased, thereby expanding the air guide range, reducing the occupied space, improving the aesthetics, and enhancing the user experience.

[0044] Second embodiment

[0045] Please refer to Figure 7 An embodiment of the present invention provides an air conditioner 100 . Compared with the first embodiment, the difference of this embodiment is that the diameter of the driving gear 152 is equal to the diameter of the intermediate gear 154 .

[0046] In this embodiment, the diameters of the driving gear 152 , the intermediate gear 154 and the driven gear 153 are all equal to facilitate manufacturing and reduce production costs.

[0047] The beneficial effects of the air conditioner 100 according to the embodiment of the present invention are the same as those of the first embodiment, and are not described in detail here.

[0048] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
