[0003] However, in existing air conditioners, the drive motor is directly installed on the back of the air outlet grille, which leads to an unstable center of gravity and increases the amount of movement during the rotation of the air drive impeller. Utility Model Content

[0004] The purpose of the utility model is to provide an air conditioner to solve the technical problem that in the existing air conditioner, the driving motor is directly installed on the back of the air outlet grille, resulting in an unstable center of gravity and an increase in the amount of movement during the rotation of the wind driving impeller.

[0005] The air conditioner provided by the utility model includes an air duct, an air outlet grille, an exhaust assembly and a pressure cover, the air duct includes an air outlet panel with an air outlet, the air outlet grille is installed at the air outlet, the air outlet grille has a rear surface facing the air duct and a front surface away from the air duct, the pressure cover is detachably connected to the front surface of the air outlet grille and together with the front surface constructs an installation cavity; the exhaust assembly includes a drive motor and a wind driving impeller driven to rotate by the drive motor, and the body of the drive motor is accommodated in the installation cavity.

[0006] By installing the drive motor on the front surface of the air outlet grille, the drive motor is located in front of the air outlet grille when the air conditioner is in use, and the installation cavity formed between the pressure cover and the front surface is used to accommodate the body of the drive motor. On the one hand, when routing the drive motor, the pressure cover can be removed and the operation can be performed from the front of the air conditioner, resulting in a large operating space and a wide field of vision. On the other hand, the center of gravity of the exhaust assembly is brought closer to the air outlet grille, thereby improving the balance and reducing the amount of movement when the drive motor is working.

[0007] After completing the wiring operation of the drive motor, the pressure cover can be assembled to the air outlet grille to cover the drive motor. On the one hand, the pressure cover can be used to limit the drive motor axially to prevent the drive motor from falling off from the front of the air outlet grille. On the other hand, it can also protect the drive motor to prevent impurities from entering the installation cavity and interfering with the normal operation of the drive motor.

[0008] Furthermore, the central portion of the air outlet grille is recessed toward the air duct to form a mounting cavity with an opening. The mounting cavity has side walls extending in the air outlet direction and a bottom wall perpendicular to the air outlet direction. The motor shaft of the drive motor extends from the bottom wall. The gland is used to cover the mounting opening. By placing the mounting cavity within the air outlet grille, the gland structure is simplified. The air outlet grille can also be used to support the drive motor, reducing vibration caused by the motor's suspension, thereby improving the operational stability of the air conditioner.

[0009] Furthermore, a first circumferential positioning structure is provided between the gland and the air outlet grille. This arrangement not only allows the gland to be pre-positioned by the first circumferential positioning structure during assembly, thereby improving assembly efficiency, but also allows the gland to be circumferentially limited after assembly, preventing rotation.

[0010] Furthermore, the first circumferential positioning structure includes a plurality of positioning blocks and a plurality of positioning slots that respectively engage with the plurality of positioning blocks in a one-to-one correspondence. One of the positioning blocks and the positioning slots is provided on the gland, and the other is provided on the air outlet grille. This method of achieving circumferential positioning of the gland by engaging the positioning blocks and the positioning slots has a simple structure and reliable positioning.

[0011] Furthermore, the air conditioner also includes a first screw, the pressure cover is provided with a first light hole, the air outlet grille is provided with a first screw hole opposite to the first light hole, and the first screw passes through the first light hole and is screwed into the first screw hole. This form of connecting the pressure cover and the air outlet grille together with the first screw is not only simple in structure, but also has a reliable connection, thereby ensuring the installation stability of the pressure cover. And / or, a limiting step is provided on the side wall of the cavity, and the pressure cover abuts against the limiting step. The setting of the above-mentioned limiting step makes it possible to limit the pressure cover along the air outlet direction when assembling the pressure cover, thereby preventing the pressure cover from being over-assembled.

[0012] Furthermore, the gland is provided with a first heat dissipation hole. By providing the first heat dissipation hole in the gland, the heat generated during the operation of the drive motor can be dissipated in time, thereby avoiding abnormalities caused by overheating of the drive motor.

[0013] Furthermore, the bottom wall of the cavity is provided with a second heat dissipation hole. This arrangement not only allows the airflow driven by the impeller to flow toward the front surface during operation of the air conditioner to enter the installation cavity through the second heat dissipation hole, thereby carrying the heat generated by the body of the drive motor to the first heat dissipation hole for discharge, thus achieving dynamic heat dissipation of the drive motor, but also, after the drive motor is shut down and the impeller stops rotating, the heat generated by the drive motor can be discharged through the second heat dissipation hole and the first heat dissipation hole, thus achieving static heat dissipation.

[0014] Furthermore, the air conditioner further includes a second screw. The air outlet grille has a second aperture formed on its edge, and the air outlet panel has a second screw hole formed on its edge opposite the second aperture. The second screw passes through the second aperture and is screwed into the second screw hole. This method of connecting the air outlet grille to the air outlet panel using the second screw not only simplifies the structure but also provides a reliable connection, thereby ensuring stable installation of the air outlet grille.

[0015] Furthermore, a second circumferential positioning structure is provided between the air outlet grille and the air outlet panel. This arrangement not only allows the air outlet grille to be pre-positioned during assembly using the second circumferential positioning structure, thereby improving assembly efficiency, but also allows the air outlet grille to be circumferentially limited after assembly to prevent rotation.

[0016] Furthermore, the second circumferential positioning structure includes a plurality of positioning posts and a plurality of positioning holes that plug and mate with the plurality of positioning posts, one of which is provided on the air outlet grille, and the other is provided on the air outlet panel. This method of circumferentially positioning the air outlet grille by plugging and mate with the positioning posts and the positioning holes is simple in structure and reliable in positioning.

[0034] By installing the drive motor 310 on the front surface 220 of the air outlet grille 200, when the air conditioner is in use, the drive motor 310 is located in front of the air outlet grille 200, and the installation cavity 230 formed between the pressure cover 400 and the front surface 220 is used to accommodate the body 311 of the drive motor 310. On the one hand, when routing the drive motor 310, the pressure cover 400 can be removed and operated from the front of the air conditioner, which provides a large operating space and a wide field of view. On the other hand, the center of gravity of the exhaust assembly 300 is closer to the air outlet grille 200, so that when the drive motor 310 is working, the balance is better and the amount of movement is reduced.
