Description

Technical Field

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

[0002] At present, most wall-mounted split air conditioner indoor units are equipped with multiple inclined air inlet plates at the air inlet to prevent foreign objects from entering the interior of the air conditioner indoor unit. However, since the air inlet is in an open state for a long time, dust can easily enter the interior of the air conditioner indoor unit from the air inlet and affect the performance of the air conditioner indoor unit. Therefore, a filter is installed inside the air conditioner indoor unit to block most of the dust.

[0003] When the air conditioner is used for a period of time or idle for a period of time, dust tends to accumulate on the filter. The dust blocks the filter and reduces the air intake, which affects the cooling or heating effect of the air conditioner to a certain extent. Therefore, users need to remove the filter regularly for cleaning. However, since the indoor unit of the wall-mounted split air conditioner is high off the ground, users need to use a stool or ladder to raise it and then disassemble the indoor unit to remove the filter for cleaning. This process is more troublesome, and frequent removal of the filter for a long time will reduce the user experience. Summary of the invention

[0004] The purpose of the present invention is to provide an air conditioner indoor unit, which can intelligently control the rotation of the air inlet plate, open the air inlet when the air conditioner is running, and close the air inlet when the air conditioner stops running, so as to prevent dust from entering through the air inlet after the air conditioner is stopped, reduce the dust on the filter screen to avoid cleaning the filter screen.

[0018] In some embodiments, an extending direction of a sliding track of at least one of the sliding grooves is different from an extending direction of a sliding track of another of the sliding grooves.

[0019] In some embodiments, pivots extending in the left-right direction are respectively provided at both ends of the front side of the air inlet plate, and shaft holes rotatably connected to the pivots are respectively opened on both sides of the air inlet of the housing.

[0020] In some embodiments, two lifting assemblies are included, and the two lifting assemblies are respectively arranged at the left and right ends of the shell; sliding shafts are respectively provided at the two ends of the rear side of the air inlet plate, and the two sliding shafts correspond to the two lifting assemblies one by one.

[0048] Please refer to Figure 1 -10. Some embodiments of the present invention provide an air-conditioning indoor unit, comprising a shell 1, an air inlet plate 2 and a lifting assembly 3; an air inlet 11 is provided at the top of the shell 1; the air inlet plate 2 is arranged at the air inlet 11, the front side of the air inlet plate 2 is pivotally connected to the shell 1, the rear side of the air inlet plate 2 is provided with a sliding shaft 22 extending along the left-right direction X, and the first end of the sliding shaft 22 is convexly arranged on the outer side of one end of the air inlet plate 2; the lifting assembly 3 is arranged on the outer side of one end of the air inlet plate 2, the lifting assembly 3 includes a lifting plate 31, and a driving mechanism 32 for driving the lifting plate 31 to lift and lower along the up-down direction Z, the lifting plate 31 is provided with a sliding groove 311 extending along the front-back direction Y, and the first end of the sliding shaft 22 is slidably arranged in the sliding groove 311.

[0049] Based on the above technical solution, the lifting plate 31 is driven to rise or fall by the lifting assembly 3, so that the sliding shaft 22 can slide forward and backward in the slide groove 311 while performing the lifting movement. The lifting movement and forward and backward sliding of the sliding shaft 22 are used to convert the rotational force of the rear side of the air inlet plate 2 to rotate around the front side of the air inlet plate 2, so as to drive the air inlet plate 2 to rotate relative to the housing 1, thereby achieving the purpose of opening or covering the air inlet 11. In addition, the present invention utilizes the lifting movement of the lifting plate 31 and the forward and backward sliding of the sliding shaft 22 to drive the air inlet plate 2 to rotate, and the structure is simple and ingenious, avoiding the problems of complex structure, low transmission ratio, unstable positioning and easy shaking of the existing method of using two gears to mesh. The air conditioner indoor unit of the present invention has a stronger sense of technology, is easier to maintain, and greatly improves the user experience.

[0050] It is understandable that the present invention does not limit the specific structure of the driving mechanism 32. For example, the driving mechanism 32 can be a cylinder or a linear module or a motor-driven gear rack, etc. Any driving mechanism 32 that can drive the lifting plate 31 to perform lifting motion is within the protection scope of the present invention.

[0051] Please refer to Figure 2 -10, in some embodiments of the present invention, the driving mechanism 32 of the present invention includes a gear 321, a support plate 322 and a motor 323; the support plate 322 is formed with a rack portion 322a extending along the up-down direction Z, the rack portion 322a is engaged with the gear 321, and the top of the support plate 322 is fixedly connected to the lifting plate 31; the motor 323 is installed in the housing 1, and the power output end of the motor 323 is connected to the gear 321. The gear 321 and the rack portion 322a are engaged with each other to convert the rotational motion of the gear 321 into the up-down sliding of the support plate 322, thereby realizing the lifting motion of the lifting plate 31.

[0052] For further information, please refer to Figure 7 , 8 In some embodiments, the indoor unit of the air conditioner of the present invention further comprises an installation box 4, the installation box 4 is fixedly arranged in the housing 1, the gear 321 and the support plate 322 are arranged inside the installation box 4, the motor 323 is fixedly arranged outside the installation box 4, and the installation box 4 is provided with a through hole through which the power output end of the power supply machine 323 passes. The installation box 4 is used to prevent dust from falling on the gear 321 and the rack to ensure the transmission stability between the gear 321 and the rack part 322a. Among them, the power output end of the motor 323 is connected to the gear 321 through a transition fit after being passed through the interior of the installation box 4, for example, by a slot key fit.

[0053] Please refer to Figure 7 -10, in some embodiments, the support plate 322 is provided with a guide groove 322b extending in the up-down direction Z, and the interior of the installation box 4 is provided with a guide wheel 41 that slides in cooperation with the guide groove 322b. The sliding cooperation between the guide wheel 41 and the guide groove 322b can limit the sliding of the support plate 322 in the up-down direction Z, thereby improving the sliding stability of the support plate 322.

[0054] In some embodiments, the motor 323 is a stepper motor, which rotates a corresponding angle through a power output shaft after receiving a pulse signal, and has high control accuracy, thereby accurately controlling the rotation angle of the air inlet plate 2 and improving the stability of the air inlet plate 2 after it stops.

[0055] It should be noted that the present invention does not limit the number or specific shape of the air inlet plates 2. For example, the number of air inlet plates 2 can be one, two, or more, and the shape of the air inlet plates 2 can be a square plate, a trapezoidal plate, or a diamond plate, etc. The number or shape of the air inlet plates 2 is specifically designed according to the size and shape of the air inlet 11. In this embodiment, the air inlet plates 2 are designed as square plates according to the existing square-shaped air inlet 11.

[0056] Please refer to Figure 1 -6. In some embodiments of the present invention, in order to increase the open area of ​​the air inlet 11 when the air conditioner indoor unit is in operation and prevent foreign objects from easily entering the housing 1 from the air inlet 11, the present invention has multiple air inlet plates 2, and multiple air inlet plates 2 are sequentially arranged at the air inlet 11 along the front-to-back direction Y, and the front side of each air inlet plate 2 is pivotally connected to the housing 1; the lifting plate 31 is provided with multiple sliding grooves 311 sequentially arranged along the front-to-back direction Y, and the multiple air inlet plates 2 correspond to the multiple sliding grooves 311 one by one. Specifically, the multiple air inlet plates 2 rotate synchronously to open or close the air inlet 11. When the air inlet 11 is opened, the air inlet 11 is divided into multiple air inlet channels by the multiple air inlet plates 2, and the multiple air inlet plates 2 are used to prevent large foreign objects from entering the housing 1 from the air inlet 11.

[0057] In some embodiments, the extension direction of the sliding track of at least one of the slide slots 311 is different from the extension direction of the sliding track of the other slide slot 311. The design of the sliding tracks of the two slide slots 311 extending in different directions can make the sliding tracks of at least two air inlet plates 2 in their respective slide slots 311 different after the driving mechanism 32 drives the lifting plate 31 to rise, so that the rotation angles of at least two air inlet plates 2 are different, and the air intake volume is controlled by reasonably adjusting the inclination angle of the air inlet plate 2 to improve the cooling or heating effect of the air conditioner. In the application process, the test data can be used to determine the working state of each air inlet plate 2 at a certain opening angle state, measure and obtain the most suitable air flow and the maximum heat exchange efficiency, and reverse the lifting height of the lifting plate 31 and the extension track of each slide slot 311 in this optimal state, thereby improving the cooling or heating effect of the air conditioner.

[0058] In some embodiments of the present invention, pivots 21 extending along the left-right direction X are respectively provided at both ends of the front side of the air inlet plate 2, and shaft holes 12 rotatably connected to the pivots 21 are respectively provided on both sides of the air inlet 11 of the housing 1. In some embodiments, the pivot 21 can form an integrated structure with the air inlet plate 2, for example, by injection molding as an integral part, so as to improve the stability of the rotation between the front side of the air inlet plate 2 and the housing 1, and facilitate the assembly between the air inlet plate 2 and the shaft hole 12. In other embodiments, the pivot 21 can be detachably connected to the air inlet plate 2. Therefore, the connection relationship between the pivot 21 and the air inlet plate 2 is not limited here.

[0059] Please refer to Figure 2 ,3 In some embodiments of the present invention, the indoor air conditioner of the present invention includes two lifting assemblies 3, which are respectively arranged at the left and right ends of the housing 1; sliding shafts 22 are respectively arranged at the rear ends of the air inlet plate 2, and the two sliding shafts 22 correspond to the two lifting assemblies 3. The rear ends of the air inlet plate 2 are synchronously driven to rotate in the same direction by the two lifting assemblies 3, thereby improving the stability of the rotation of the air inlet plate 2, avoiding the shaking phenomenon caused by uneven force on one end of the air inlet plate 2, and improving the stability of the air inlet plate 2 after it stops. At the same time, the two ends of the front side of the air inlet plate 2 after it is stationary are restricted in movement or swinging by the pivot 21, and the two ends of the rear side of the air inlet plate 2 are restricted in movement or swinging in the slide groove 311 by the sliding shaft 22, so that the front and rear sides of the air inlet plate 2 are both force-limited. By limiting the movement of the front and rear sides of the air inlet plate to balance the force of the air inlet plate 2, the swinging of the rear side of the air inlet plate 2 in a stationary state is restricted, ensuring that the air inlet plate 2 is always in a stable state after rotation, preventing the rear side of the air inlet plate 2 from shaking or swinging, avoiding noise and ensuring the stability of the air intake volume.

[0060] Please refer to Figure 6 In some embodiments of the present invention, the first end of the sliding shaft 22 forms a limit enclosure 221, and the limit enclosure 221 can limit the first end of the sliding shaft 22 in the slide groove 311 to prevent the sliding shaft 22 from falling off the slide groove 311. The installation method of the sliding shaft 22 is: a sleeve with a hole is provided at the rear end of the air inlet plate 2, and the second end of the sliding shaft 22 passes through the slide groove 311 and is clamped in the sleeve.

[0061] The working process of the air conditioner indoor unit of the present invention is as follows: when the air conditioner needs to be operated, the air conditioner mainboard controls the motor 323 to drive the gear 321 to rotate clockwise by a certain angle (it is assumed here that the gear 321 rotates clockwise to drive the support plate 322 to rise), driving the lifting plate 31 to rise to a certain height, thereby causing the multiple sliding shafts 22 to rise to a certain height and slide backwards in the corresponding slide grooves 311 for a certain distance, thereby driving the rear side of each air inlet plate 2 to rotate clockwise around the front side of the air inlet plate 2, so that the air inlet 11 is opened, and the indoor hot air enters the shell 1 from the air inlet 11 to form a cold air air is delivered; when the air conditioner stops running, the air conditioner main board controls the motor 323 to drive the gear 321 to rotate counterclockwise by a certain angle, driving the lifting plate 31 to descend to a certain height, thereby causing the multiple sliding shafts 22 to descend to a certain height and slide forward a certain distance in the corresponding slide groove 311, thereby driving the rear side of each air inlet plate 2 to rotate counterclockwise around the front side of the air inlet plate 2, so that the multiple air inlet plates 2 cover the air inlet 11, so that the air inlet 11 is closed, avoiding dust from entering from the air inlet 11 after the air conditioner is stopped, reducing the dust on the filter to avoid cleaning the filter, thereby improving the user experience.

[0062] In summary, the embodiment of the present invention provides an air-conditioning indoor unit, which drives the lifting plate 31 to rise or fall through the lifting assembly 3, so that the sliding shaft 22 can slide forward and backward in the slide groove 311 while performing the lifting movement, and the lifting and backward sliding movement of the sliding shaft 22 can convert the rotational force of the rear side of the air inlet plate 2 to rotate around the front side of the air inlet plate 2, so as to drive the air inlet plate 2 to rotate relative to the housing 1, thereby achieving the purpose of opening or covering the air inlet 11. The air-conditioning indoor unit of the present invention controls the rotation of the air inlet plate 2 by intelligently controlling the rotation of the air inlet plate 2. When the air conditioner is running, the air inlet plate 2 is driven to rotate to a certain tilt angle to open the air inlet 11; when the air conditioner stops running, the air inlet plate 2 is driven to cover the air inlet 11 to close the air inlet 11, so as to prevent dust from entering from the air inlet 11 after the air conditioner is stopped, reduce the dust on the filter net to avoid cleaning the filter net, and thus improve the user experience.
