Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly relates to an air conditioner and an installation method thereof. Background Art

[0002] With the increasing improvement of people's living standards, air conditioners have become an indispensable household appliance. At present, air conditioners are usually provided with rotatable air deflector plates, and a driving box is used to drive the air deflector plates to rotate so as to direct the air flow blown out by the air conditioner, thereby realizing the function of adjusting the air direction. The current driving boxes are generally divided into two installation methods: internal and external (relative to the middle frame). If the driving box is arranged outside the middle frame, it occupies a large space and affects the aesthetics of the air conditioner. If the driving box is arranged inside the middle frame, it is difficult to disassemble and assemble, and it is not convenient for maintenance and servicing. Summary of the Invention

[0003] The problem solved by the present invention is how to simplify the disassembly and assembly process, improve the disassembly and assembly efficiency, and facilitate maintenance and servicing when the driving box is installed inside.

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

[0005] In a first aspect, the present invention provides an air conditioner, including a middle frame and a driving box. The middle frame includes a connecting plate and a limiting plate. One end of the connecting plate is connected to the limiting plate, and the other end is provided with a reinforcing rib. The reinforcing rib extends to be provided with a stop portion. An assembly cavity is formed between the stop portion and the limiting plate. The limiting plate is provided with a through hole, and the through hole communicates with the assembly cavity. The driving box includes a box body, an elastic member, and a transmission rod. The elastic member is installed in the box body and is connected to the transmission rod. The transmission rod is slidably matched with the box body and partially extends out of the box body. The gap between the stop portion and the limiting plate is smaller than the projection length of the driving box in the axial direction of the transmission rod. The limiting plate is used to overcome the elastic force of the elastic member and press the transmission rod into the box body when the box body moves relative to the stop portion. The elastic member is used to drive the transmission rod to reset and pass through the through hole when the box body moves to the assembly cavity. Compared with the prior art, since the air conditioner provided by the present invention adopts the stop portion and the limiting plate that jointly form the assembly cavity and the elastic member connected to the transmission rod, the disassembly and assembly process can be simplified, the disassembly and assembly efficiency can be improved, and the maintenance and servicing are facilitated when the driving box is installed inside.

[0006] Further, the box body is provided with an abutting wall and an installation wall oppositely. The abutting wall abuts against the limiting plate. The abutting wall is provided with an opening hole, and the opening hole is aligned with the through hole. The transmission rod passes through the opening hole. The installation wall is spaced from the stop portion. The limiting plate can stop and limit the abutting wall to assist in fixing the relative position of the box body and the middle frame and prevent the box body from displacing relative to the middle frame. A space margin is left between the installation wall and the stop portion to facilitate the installation and disassembly of the driving box.

[0007] Further, the installation wall is provided with a guiding inclined surface which is inclined with respect to the abutting wall and is used for slidingly cooperating with the stopping portion so that the limiting plate overcomes the elastic force of the elastic member and continuously presses the transmission rod into the box body. The guiding inclined surface can play a guiding role, facilitating the user to install the box body into the assembly cavity, achieving the effect of labor saving and further improving the installation efficiency.

[0008] Further, the driving box further includes a driving motor and a transmission assembly. The transmission assembly is installed in the box body. The input end of the transmission assembly is connected to the driving motor, and the output end of the transmission assembly is connected to the transmission rod. The elastic member is connected between the transmission assembly and the transmission rod. The transmission rod can overcome the elastic force of the elastic member and slide relative to the transmission assembly under the action of an external force, and can also slide back relative to the transmission assembly under the elastic force of the elastic member. The transmission assembly can drive the transmission rod to rotate when the transmission rod slides to any position relative to the transmission assembly, ensuring the stability of the transmission process.

[0009] Further, the transmission assembly includes a driving gear, a first transmission gear, a second transmission gear and a driven gear. The driving gear, the first transmission gear, the second transmission gear and the driven gear are all rotatably installed in the box body. The output shaft of the driving motor is connected to the driving gear. The driving gear meshes with the first transmission gear. The first transmission gear is sleeved outside the second transmission gear and cooperates with the second transmission gear. The second transmission gear meshes with the driven gear. The driven gear is connected to the transmission rod through the elastic member. The driving motor is used to drive the driving gear to rotate, and the driving gear can drive the transmission rod to rotate through the first transmission gear, the second transmission gear and the driven gear in sequence, thereby driving the air guiding plate to rotate.

[0010] Further, the driven gear is provided with a fitting hole, and the transmission rod is slidably fitted with the fitting hole. A limiting ring is provided on the peripheral surface of the transmission rod. The elastic member is sleeved outside the transmission rod. One end of the elastic member abuts against the limiting ring, and the other end abuts against the driven gear. The elastic member is always in a compressed state and can apply an elastic force to the limiting ring so that the entire transmission rod has a tendency to slide out of the fitting hole.

[0011] Further, the middle frame further includes an end plate which is connected to the connecting plate and is spaced from the limiting plate. The end plate is provided with a relief opening. The box body is installed on the end plate and partially passes through the relief opening. The box body needs to partially pass through the relief opening during the installation process. The end plate is used to fix the position of the box body to prevent the box body from shaking in the assembly cavity and ensure the stability of the box body installation.

[0012] Furthermore, the middle frame further comprises a panel, which is connected to the edge of the end plate and is arranged on the side of the end plate away from the limiting plate, the panel is connected to the connecting plate, the panel, the connecting plate and the end plate together form a receiving cavity, and the receiving cavity is connected to the clearance opening. The driving motor is arranged in the receiving cavity, the box body part is arranged through the clearance opening, and is arranged in the receiving cavity and the assembly cavity at the same time, so as to realize the internalization of the entire driving box, reduce the occupied space, and improve the aesthetics of the air conditioner.

[0013] Furthermore, the middle frame also includes an extension plate, which is connected between the stopper and the limit plate, and is disposed below the box body, and is used to support the box body, so as to fix the position of the box body, prevent the box body from shaking in the assembly cavity, and further ensure the stability of the box body installation.

[0014] In a second aspect, the present invention provides an air conditioner installation method, which is applied to the above-mentioned air conditioner, and the air conditioner installation method comprises: extending the box body into the middle frame along the first direction until the transmission rod abuts against the limit plate; moving the box body relative to the stopper along the second direction so that the limit plate overcomes the elastic force of the elastic member and presses the transmission rod into the box body until the box body moves to the assembly cavity, and the transmission rod is reset under the action of the elastic member and passes through the through hole, wherein the second direction is perpendicular to the first direction. The air conditioner installation method can simplify the disassembly and assembly process when the drive box is built-in, improve the disassembly and assembly efficiency, and facilitate maintenance and maintenance.

Specific embodiments

[0024] To make the above - mentioned objects, features, and advantages of the present invention more obvious and understandable, the following detailed description will be given to the specific embodiments of the present invention with reference to the accompanying drawings.

[0025] Please refer to Figures 1 to 7 , the embodiment of the present invention provides an air conditioner 100 for regulating the indoor temperature. It can simplify the disassembly and assembly process when the driving box 130 is built - in, improve the disassembly and assembly efficiency, and facilitate maintenance and servicing.

[0026] It should be noted that the air conditioner 100 is a wall - mounted air conditioner, which is hung on the wall and can blow hot air or cold air into the room to achieve the functions of heating or cooling.

[0027] The air conditioner 100 includes a middle frame 110, a side cover plate 120, a driving box 130, a wind deflector (not shown in the figure), a fan (not shown in the figure), and a heat exchanger (not shown in the figure). Among them, the driving box 130, the wind deflector, the fan, and the heat exchanger are all installed in the middle frame 110. The fan is used to generate negative pressure to drive the air flow and form an outlet air flow, and the heat exchanger is used to exchange heat with the outlet air flow so that the outlet air flow has the function of heating or cooling. Specifically, the driving box 130 is connected to the wind deflector, and the driving box 130 is used to drive the wind deflector to rotate. The wind deflector is used to guide the outlet air flow to achieve the function of adjusting the wind direction. The side cover plate 120 covers the side of the middle frame 110 and is detachably connected to the middle frame 110 to achieve the shielding and protection of the driving box 130 and improve the aesthetics of the air conditioner 100.

[0028] The middle frame 110 includes a connecting plate 111 and a limiting plate 112. The connecting plate 111 is connected to the limiting plate 112. One end of the connecting plate 111 is connected to the limiting plate 112, and a reinforcing rib 1111 is provided at the other end. The reinforcing rib 1111 is spaced from the limiting plate 112. A stop portion 1112 extends from the reinforcing rib 1111. An assembly cavity 140 is formed between the stop portion 1112 and the limiting plate 112 for installing the drive box 130. Specifically, the air guiding plate is rotatably installed on the side of the limiting plate 112 away from the assembly cavity 140. The limiting plate 112 is provided with a through hole 1121 that communicates with the assembly cavity 140. The drive box 130 installed in the assembly cavity 140 can pass through the through hole 1121 and is connected to the air guiding plate to realize the function of driving the air guiding plate to rotate.

[0029] The drive box 130 includes a box body 131, an elastic member 132, and a transmission rod 133. The elastic member 132 is installed in the box body 131 and is connected to the transmission rod 133. The transmission rod 133 is slidably engaged with the box body 131 and partially extends out of the box body 131. The transmission rod 133 can overcome the elastic force of the elastic member 132 under an external force and retract into the box body 131, and the transmission rod 133 can also reset and extend out of the box body 131 under the elastic force of the elastic member 132.

[0030] Further, the gap between the stop portion 1112 and the limiting plate 112 is smaller than the projected length of the drive box 130 in the axial direction of the transmission rod 133, and the gap between the stop portion 1112 and the limiting plate 112 is greater than or equal to the projected length of the box body 131 in the axial direction of the transmission rod 133. That is, during the installation of the drive box 130, it is necessary to press the transmission rod 133 into the box body 131 against the elastic force of the elastic member 132 to ensure that the box body 131 can be inserted into the assembly cavity 140. Specifically, the limiting plate 112 is used to overcome the elastic force of the elastic member 132 and press the transmission rod 133 into the box body 131 when the box body 131 moves relative to the stop portion 1112, so that the projected length of the entire drive box 130 in the axial direction of the transmission rod 133 is reduced, facilitating the insertion of the box body 131 into the assembly cavity 140; the elastic member 132 is used to drive the transmission rod 133 to reset and pass through the through hole 1121 when the box body 131 moves to the assembly cavity 140. At this time, the transmission rod 133 is no longer under the pressing force of the limiting plate 112, and the projected length of the entire drive box 130 in the axial direction of the transmission rod 133 returns to the original length.

[0031] During the installation of the drive box 130, first, use an external force to overcome the elastic force of the elastic member 132 and press the transmission rod 133 into the box body 131, and use an external force to drive the box body 131 to move to the assembly cavity 140; when the transmission rod 133 moves to a position corresponding to the through hole 1121, the transmission rod 133 extends out of the box body 131 under the elastic force of the elastic member 132, completing the installation of the drive box 130. Similarly, during the disassembly of the drive box 130, first use an external force to press the transmission rod 133 into the box body 131 so that the transmission rod 133 exits the through hole 1121, and use an external force to drive the box body 131 to exit the assembly cavity 140; when the box body 131 completely exits, the transmission rod 133 extends out of the box body 131 under the elastic force of the elastic member 132, completing the disassembly of the drive box 130. In this way, when the drive box 130 is installed, the drive box 130 is arranged between the stop portion 1112 and the limiting plate 112 to realize the function of the drive box 130 being built into the middle frame 110, and the disassembly and assembly process is simple and fast, effectively improving the disassembly and assembly efficiency and facilitating the maintenance and repair of the drive box 130.

[0032] It should be noted that the box body 131 is provided with a supporting wall 1311 and a mounting wall 1312 oppositely. The supporting wall 1311 abuts against the limiting plate 112, and the limiting plate 112 can stop and limit the supporting wall 1311 to assist in fixing the relative position of the box body 131 and the middle frame 110 and prevent the box body 131 from displacing relative to the middle frame 110. The mounting wall 1312 is spaced from the stop portion 1112, that is, there is a space margin between the mounting wall 1312 and the stop portion 1112 to facilitate the installation and disassembly of the drive box 130. Specifically, the supporting wall 1311 is provided with an opening 1313, and the opening 1313 is aligned with the through hole 1121, and the transmission rod 133 is arranged through the opening 1313 to facilitate the transmission rod 133 to pass through the through hole 1121 and be connected to the air deflector.

[0033] Further, the installation wall 1312 is provided with a guiding inclined surface 1314, which is inclined with respect to the abutting wall 1311. The guiding inclined surface 1314 is used for sliding cooperation with the stopping portion 1112, so that the limiting plate 112 overcomes the elastic force of the elastic member 132 and continuously presses the transmission rod 133 into the box body 131. Specifically, during the installation process of the driving box 130, first insert the driving box 130 into the middle frame 110, so that the guiding inclined surface 1314 abuts against the stopping portion 1112, and the transmission rod 133 abuts against the limiting plate 112. Subsequently, apply an external force to the driving box 130 to push the box body 131 into the assembly cavity 140. During this process, the guiding inclined surface 1314 slides relative to the stopping portion 1112, and the transmission rod 133 is compressed into the box body 131 until the box body 131 is assembled in place, and the transmission rod 133 extends out of the through hole 1121 under the elastic force of the elastic member 132. In this way, during the movement of the box body 131, the guiding inclined surface 1314 can play a guiding role, facilitating the user to install the box body 131 into the assembly cavity 140, achieving the effect of labor saving and further improving the installation efficiency.

[0034] In this embodiment, the installation wall 1312 is further provided with a first back surface 1315 and a second back surface 1316. The first back surface 1315 and the second back surface 1316 are arranged in parallel at intervals and are both parallel to the abutting wall 1311. The guiding inclined surface 1314 is connected between the first back surface 1315 and the second back surface 1316 and is inclined with respect to the first back surface 1315 and the second back surface 1316. Specifically, during the installation process of the driving box 130, the first back surface 1315, the guiding inclined surface 1314, and the second back surface 1316 enter the assembly cavity 140 in sequence, and the guiding inclined surface 1314 slides in cooperation with the stopping portion 1112. After the installation of the driving box 130 is completed, the first back surface 1315, the guiding inclined surface 1314, and the second back surface 1316 are all arranged at intervals with the stopping portion 1112 to leave a space margin for easy disassembly.

[0035] It should be noted that the driving box 130 further includes a driving motor 134 and a transmission assembly 135. The driving motor 134 is installed outside the box body 131, and the transmission assembly 135 is installed inside the box body 131. The input end of the transmission assembly 135 is connected to the driving motor 134, and the output end of the transmission assembly 135 is connected to the transmission rod 133. The driving motor 134 can drive the transmission rod 133 to rotate through the transmission assembly 135, thereby driving the air deflector to rotate, and further realizing the function of adjusting the air direction of the air conditioner 100. Specifically, the elastic member 132 is connected between the transmission assembly 135 and the transmission rod 133. The transmission rod 133 can overcome the elastic force of the elastic member 132 and slide relative to the transmission assembly 135 under the action of an external force. The transmission rod 133 can also slide back relative to the transmission assembly 135 under the elastic force of the elastic member 132. The transmission assembly 135 can drive the transmission rod 133 to rotate when the transmission rod 133 slides to any position relative to the transmission assembly 135, so as to ensure the stability of the transmission process.

[0036] The transmission assembly 135 includes a driving gear 1351, a first transmission gear 1352, a second transmission gear 1353, and a driven gear 1354. The driving gear 1351, the first transmission gear 1352, the second transmission gear 1353, and the driven gear 1354 are all rotatably installed inside the box body 131. The output shaft of the driving motor 134 is connected to the driving gear 1351, and the driving motor 134 is used to drive the driving gear 1351 to rotate. The driving gear 1351 meshes with the first transmission gear 1352. The first transmission gear 1352 is sleeved outside the second transmission gear 1353 and cooperates with the second transmission gear 1353. The driving gear 1351 can drive the second transmission gear 1353 to rotate through the first transmission gear 1352. The second transmission gear 1353 meshes with the driven gear 1354. The driven gear 1354 is connected to the transmission rod 133 through the elastic member 132. The second transmission gear 1353 can drive the transmission rod 133 to rotate through the driven gear 1354, thereby driving the air deflector to rotate.

[0037] In this embodiment, the driven gear 1354 is provided with a mating hole 1355. The transmission rod 133 is slidably mated with the mating hole 1355. The driven gear 1354 and the transmission rod 133 are coaxially arranged, and the transmission rod 133 can slide axially relative to the mating hole 1355. A limiting ring 1331 is arranged on the peripheral surface of the transmission rod 133. The elastic member 132 is sleeved outside the transmission rod 133. One end of the elastic member 132 abuts against the limiting ring 1331, and the other end abuts against the driven gear 1354. The elastic member 132 is always in a compressed state. The elastic member 132 can exert an elastic force on the limiting ring 1331 so that the entire transmission rod 133 has a tendency to slide out of the mating hole 1355. Specifically, the outer diameter of the limiting ring 1331 is larger than the aperture of the opening 1313 on the abutting wall 1311. The abutting wall 1311 can stop the limiting ring 1331 to prevent the limiting ring 1331 from protruding out of the opening 1313, thereby preventing the transmission rod 133 from disengaging from the mating hole 1355 and ensuring the stability of the cooperation between the driven gear 1354 and the transmission rod 133.

[0038] Further, the mating hole 1355 is provided with an anti-rotation inner wall 1356, and the transmission rod 133 is provided with an abutting surface 1332. The anti-rotation inner wall 1356 and the abutting surface 1332 cooperate to prevent the transmission rod 133 from rotating relative to the mating hole 1355 and ensure the stability of the driven gear 1354 driving the transmission rod 133 to rotate.

[0039] In this embodiment, the cross-section of the mating hole 1355 is hexagonal, and the shape of the transmission rod 133 matches the shape of the mating hole 1355 to ensure the stability of the transmission process. However, this is not limited thereto. In other embodiments, the cross-section of the mating hole 1355 can be rectangular or semi-circular, and the shapes of the mating hole 1355 and the transmission rod 133 are not specifically limited.

[0040] It should be noted that the middle frame 110 further includes an end plate 113, a surrounding plate 114, and an extension plate 115. The end plate 113 is connected to the connection plate 111 and is spaced from the limiting plate 112. The end plate 113 is provided with a relief opening 1131. The box body 131 is installed on the end plate 113 and partially passes through the relief opening 1131, that is, the box body 131 needs to partially pass through the relief opening 1131 during the installation process. The end plate 113 is used to fix the position of the box body 131 to prevent the box body 131 from shaking in the assembly cavity 140 and ensure the stability of the installation of the box body 131.

[0041] In this embodiment, the box body 131 and the end plate 113 are connected by screws. However, this is not limited thereto. In other embodiments, the box body 131 can be snap-connected to the end plate 113 or riveted to the end plate 113, and the connection method between the box body 131 and the end plate 113 is not specifically limited.

[0042] Furthermore, the enclosure 114 is connected to the edge of the end plate 113 and is arranged on a side of the end plate 113 away from the limit plate 112. The enclosure 114 is connected to the connecting plate 111 (one end of the enclosure 114 is connected to one end of the connecting plate 111, and the other end of the enclosure 114 is connected to the stop portion 1112 of the reinforcing rib 1111 arranged on the connecting plate 111). The enclosure 114, the connecting plate 111 and the end plate 113 together form a accommodating cavity 150. The accommodating cavity 150 is connected to the make way port 1131. The driving motor 134 is arranged in the accommodating cavity 150. The box body 131 is partially arranged through the make way port 1131, and is simultaneously arranged in the accommodating cavity 150 and the assembly cavity 140, so as to realize the built-in of the entire driving box 130, reduce the occupied space, and improve the aesthetics of the air conditioner 100. Specifically, the side cover plate 120 is disposed outside the accommodating cavity 150 and is detachably connected to the end plate 113 . The side cover plate 120 is used to shield and protect the driving box 130 and improve the aesthetics of the air conditioner 100 .

[0043] Preferably, the extension plate 115 is connected between the stop portion 1112 and the limiting plate 112, and is connected to the enclosure 114. The extension plate 115 is arranged below the box body 131. The stop portion 1112, the extension plate 115 and the limiting plate 112 together form an assembly cavity 140. The extension plate 115 is used to support the box body 131 to fix the position of the box body 131 and prevent the box body 131 from shaking in the assembly cavity 140, thereby further ensuring the stability of the installation of the box body 131.

[0044] In this embodiment, the connecting plate 111, the limiting plate 112, the end plate 113, the surrounding plate 114 and the extension plate 115 are integrally formed to improve the connection strength, but it is not limited to this. In other embodiments, the connecting plate 111, the limiting plate 112, the end plate 113, the surrounding plate 114 and the extension plate 115 can also be arranged separately and connected together by bonding or snapping. The connection method of the connecting plate 111, the limiting plate 112, the end plate 113, the surrounding plate 114 and the extension plate 115 is not specifically limited.

[0045] The embodiment of the present invention further provides an installation method of an air conditioner 100, which is applied to the above-mentioned air conditioner 100. The installation method of the air conditioner 100 includes:

[0046] Step S110 : Extend the box body 131 into the middle frame 110 along the first direction until the transmission rod 133 abuts against the limiting plate 112 .

[0047] It should be noted that in step S110 , the side cover 120 is first removed from the end plate 113 to expose the clearance opening 1131 on the end plate 113 , and then the box body 131 is inserted into the clearance opening 1131 along the first direction until the transmission rod 133 abuts against the limit plate 112 .

[0048] Step S120: Move the box body 131 relative to the stopper 1112 in the second direction, so that the limiting plate 112 overcomes the elastic force of the elastic member 132 and presses the transmission rod 133 into the box body 131 until the box body 131 moves to the assembly cavity 140. The transmission rod 133 is reset under the action of the elastic member 132 and passes through the through hole 1121, where the second direction is perpendicular to the first direction.

[0049] It should be noted that in step S120, first move the box body 131 relative to the stopper 1112 in the second direction. During this process, the guiding inclined surface 1314 of the mounting wall 1312 slides relative to the stopper 1112, so that the limiting plate 112 overcomes the elastic force of the elastic member 132 and continuously presses the transmission rod 133 into the box body 131; when the box body 131 is assembled in place, the box body 131 is simultaneously disposed in the accommodation cavity 150 and the assembly cavity 140. At this time, the abutting wall 1311 abuts against the limiting plate 112, and the through hole 1313 of the abutting wall 1311 is aligned with the through hole 1121 of the limiting plate 112. The limiting plate 112 no longer applies a holding force to the transmission rod 133, and the transmission rod 133 passes through the through hole 1121 under the elastic force of the elastic member 132; then use screws to connect the box body 131 to the end plate 113 to realize the fixing function of the box body 131; finally, install the side cover plate 120 on the end plate 113 to shield and protect the drive box 130, and complete the installation of the drive box 130.

[0050] In the air conditioner 100 according to the embodiment of the present invention, the middle frame 110 includes a connecting plate 111 and a limiting plate 112. One end of the connecting plate 111 is connected to the limiting plate 112, and a reinforcing rib 1111 is provided at the other end. A stop portion 1112 extends from the reinforcing rib 1111. An assembly cavity 140 is formed between the stop portion 1112 and the limiting plate 112. The limiting plate 112 is provided with a through hole 1121, and the through hole 1121 communicates with the assembly cavity 140. The driving box 130 includes a box body 131, an elastic member 132, and a transmission rod 133. The elastic member 132 is installed in the box body 131 and is connected to the transmission rod 133. The transmission rod 133 is slidably matched with the box body 131 and partially extends out of the box body 131. The gap between the stop portion 1112 and the limiting plate 112 is smaller than the projection length of the driving box 130 in the axial direction of the transmission rod 133. The limiting plate 112 is configured to press the transmission rod 133 into the box body 131 by overcoming the elastic force of the elastic member 132 when the box body 131 moves relative to the stop portion 1112. The elastic member 132 is configured to drive the transmission rod 133 to reset and pass through the through hole 1121 when the box body 131 moves to the assembly cavity 140. Compared with the prior art, since the air conditioner 100 provided by the present invention adopts the stop portion 1112 and the limiting plate 112 that jointly form the assembly cavity 140 and the elastic member 132 connected to the transmission rod 133, the disassembly and assembly process can be simplified, the disassembly and assembly efficiency can be improved, and maintenance and servicing are facilitated when the driving box 130 is built-in. The installation method of the air conditioner 100 has simple steps and high installation efficiency.

[0051] 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 protection scope of the present invention should be defined by the scope of the claims.
