Description

Technical Field

[0001] This application relates to the technical field of air conditioning equipment, and more particularly to an indoor air conditioning unit. Background Technology

[0002] An air conditioner, also known as an air conditioning unit, is a device that uses artificial means to regulate and control parameters such as temperature, humidity, and airflow within a building or structure. To meet the needs of daily life, some air conditioners have a fresh air function, which can transfer outdoor air into the room.

[0003] An air conditioner typically includes a casing with an air inlet. Inside the casing are an indoor heat exchanger and an indoor fan. An air conditioner usually contains a filter. Indoor air enters the casing through the air inlet under the action of the indoor fan and is filtered by the filter. Furthermore, some air conditioners include a cleaning module that filters the filter. This module typically has a first drive roller and a second drive roller. The two ends of the filter are wound onto the first and second drive rollers respectively, facilitating the movement of the filter and enabling the cleaning module to clean it.

[0004] However, in the existing technology, both ends of the filter screen are directly wound onto the first and second drive rollers. Therefore, when the filter screen is damaged or requires maintenance, the entire cleaning module needs to be disassembled, and the first and second filter screens need to be separated from the first and second drive rollers. This operation is complicated and cumbersome, and the cleaning module is easily damaged during disassembly. Utility Model Content

[0005] This utility model solves, to at least a certain extent, one of the technical problems in the related art.

[0006] Therefore, this application aims to provide an air conditioning indoor unit in which the filter is detachably connected to a synchronous belt. The filter moves together with the synchronous belt, allowing the filter to circulate along a specific path and switch functions at different positions. When it is necessary to disassemble, replace, or maintain the filter, the filter can be directly detached from the synchronous belt without removing the entire cleaning module. This greatly simplifies filter maintenance and management, improves filter utilization efficiency and the flexibility of the overall filtration system, and ensures good air filtration performance of the air conditioning indoor unit during long-term operation. It also helps protect components such as the indoor heat exchanger and fan, extending their service life and improving the overall performance and reliability of the air conditioning indoor unit. This solves the technical problems of complex and cumbersome operation processes and the risk of damage to the cleaning module during disassembly in existing technologies.

[0007] To achieve the above objectives, this utility model provides an indoor air conditioning unit, comprising:

[0008] The casing has an air conditioning inlet at the top;

[0009] An indoor heat exchanger is arranged inside the shell;

[0010] An indoor fan is arranged inside the shell; the indoor fan enables air flow to enter the shell through the air conditioner air inlet and to be input to the indoor environment after heat exchange through the indoor heat exchanger;

[0011] A filter module is arranged inside the shell, and the filter module comprises:

[0012] A support frame;

[0013] Two first synchronous wheels are arranged along the axial direction and rotate synchronously; the two first synchronous wheels are rotatably connected to one end of the support frame;

[0014] Two second synchronous wheels are arranged along the axial direction and rotate synchronously; the two second synchronous wheels are rotatably connected to the end of the support frame away from the first synchronous wheels;

[0015] Two synchronous belts are respectively sleeved on the corresponding first synchronous wheels and second synchronous wheels;

[0016] A filter screen, the two sides of the filter screen in the width direction are respectively detachably connected to the two synchronous belts;

[0017] A cleaning module is arranged for cleaning the filter screen.

[0018] In the technical scheme, the air conditioner air inlet at the top of the shell provides a channel for air to enter the air conditioner indoor unit, enabling indoor air to smoothly enter the subsequent processing flow. The indoor heat exchanger exchanges heat with air through refrigerant circulation in the shell, achieving refrigeration or heating effect and adjusting indoor air temperature. The indoor fan drives air flow to enter the shell from the air inlet, and then to be output to the indoor environment after heat exchange through the heat exchanger, ensuring the circulation power of air and enabling the indoor temperature to be uniformly distributed and maintained at a set state. The support frame of the filter module provides stable support for each component. The first synchronous wheel and the second synchronous wheel provide a mounting basis for the synchronous belt. The synchronous belt can rotate under the action of the first synchronous wheel and the second synchronous wheel. The filter screen is detachably connected to the synchronous belt, and the filter screen moves together with the synchronous belt, so that the filter screen can move in a specific path and realize function switching at different positions. When the filter screen needs to be detached, replaced or maintained, the filter screen and the synchronous belt can be directly detached. The cleaning module does not need to be completely removed. This greatly facilitates the maintenance and management of the filter screen, improves the use efficiency of the filter screen and the flexibility of the overall filtering system, and ensures that the air conditioner indoor unit always has good air filtering effect during long-time operation, which helps to protect the indoor heat exchanger and the fan and other components, prolongs the service life thereof, and improves the overall performance and reliability of the air conditioner indoor unit.

[0019] In some embodiments of the present application, the filter screen and the synchronous belt are connected by a Velcro.

[0020] In the technical solution, the filter screen and the synchronous belt are connected by a Velcro, which is convenient and repeatable. When the user needs to disassemble the filter screen for cleaning or replacement, he or she does not need to use professional tools, but only needs to separate the filter screen by a simple operation. When installing, the filter screen can be quickly aligned and attached, which greatly reduces the difficulty and time cost of filter screen maintenance, improves the convenience and experience of the user using the air conditioner indoor unit, and also encourages the user to regularly maintain the filter screen, thereby ensuring the good operation of the air conditioning system.

[0021] In some embodiments of the present application, the filter screen and the synchronous belt are connected by an adhesive.

[0022] In the technical solution, the filter screen and the synchronous belt are connected by an adhesive, which can provide a relatively firm connection effect. During the circulation movement of the synchronous belt driving the filter screen, the filter screen can be effectively prevented from falling off or shifting due to factors such as vibration and air flow impact, ensuring that the filter screen is always in the correct working position and ensuring the continuity and stability of the filtering work. At the same time, the adhesive connection is relatively simple and low in cost, which helps to reduce the production cost and assembly difficulty of the air conditioner indoor unit and improve the production efficiency on the premise of ensuring the reliability of the connection. When maintenance is needed, the filter screen can be directly torn off and then reattached after reapplying the adhesive.

[0023] In some embodiments of the present application, a first deflection roller is arranged between the two first synchronous wheels, and the two ends of the first deflection roller are coaxially connected to the two first synchronous wheels, respectively.

[0024] A second deflection roller is arranged between the two second synchronous wheels, and the two ends of the second deflection roller are coaxially connected to the two second synchronous wheels, respectively.

[0025] In the technical solution, the first deflection roller ensures that the two first synchronous wheels rotate synchronously, and the second deflection roller ensures that the two second synchronous wheels rotate synchronously. This ensures that the two synchronous belts have the same rotation direction and speed, avoids the occurrence of adverse phenomena such as jamming during the operation of the two synchronous belts, and ensures that the filter screen does not wrinkle.

[0026] In some embodiments of the present application, the cleaning module further comprises:

[0027] A first driving member is arranged in the housing.

[0028] A first driving gear is arranged at the end of the first driving member.

[0029] One end of the first synchronous wheel is fixedly connected with a first gear; the first driving gear is engaged with the first gear.

[0030] In the technical scheme, the first driving member serves as a power source, and the rotation speed, direction and start-stop of the first synchronous wheel can be accurately controlled through the meshing transmission of the driving gear and the first gear. Through the rotation of the first synchronous wheel, the rotation of the synchronous belt is driven, and the movement of the filter screen is realized.

[0031] In some embodiments of the present application, the cleaning module further comprises:

[0032] A cleaning brush is arranged in the shell, and the cleaning brush contacts the filter screen.

[0033] In the technical scheme, when the filter screen passes through the cleaning brush under the driving of the synchronous belt, the cleaning brush can effectively remove dust, hair, fibers and other pollutants adsorbed on the surface of the filter screen through the friction between the bristles of the cleaning brush and the surface of the filter screen. Through regular or real-time cleaning operation, the pores of the filter screen are kept unobstructed, the good air permeability and filtering efficiency of the filter screen are maintained, and problems such as reduction of air flow, reduction of air pressure and reduction of heat exchange efficiency caused by filter screen blockage are prevented, so that the air conditioner indoor unit can continuously and stably operate, a comfortable indoor air environment is provided, energy waste and equipment failure risk caused by filter screen blockage are reduced, and the energy utilization efficiency and reliability of the air conditioning system are improved.

[0034] In some embodiments of the present application, the cleaning module further comprises:

[0035] A tooth comb is arranged on the support frame.

[0036] A second driving member is arranged in the shell; the second driving member is used to drive the cleaning brush to rotate and contact the tooth comb.

[0037] In the technical scheme, the tooth comb is used to comb the cleaning brush. After the cleaning brush cleans the filter screen, the second driving member drives the cleaning brush to rotate and contact the tooth comb. The tooth comb can comb off the dust and impurities adsorbed on the cleaning brush, prevent the cleaning brush from being sticky, hard and losing elasticity due to long-term accumulation of dirt, and ensure that the cleaning performance of the cleaning brush is always consistent. This design can prolong the service life of the cleaning brush, reduce the replacement frequency of the cleaning brush, reduce the maintenance cost, and also ensure that the cleaning brush can achieve good cleaning effect every time the filter screen is cleaned, further improve the cleaning efficiency and reliability of the filter module, and ensure that the air filtering system of the air conditioner indoor unit can continuously and stably operate.

[0038] In some embodiments of the present application, the cleaning module further comprises:

[0039] A second driving gear is driven to rotate by the second driving member;

[0040] A second gear is arranged at an end of the cleaning brush and engaged with the second driving gear.

[0041] In the technical scheme, the gear transmission mode can accurately and efficiently transmit the power of the second driving member to the cleaning brush, so that the cleaning brush can rotate and contact the tooth comb, thereby achieving cleaning of the cleaning brush. Through accurate transmission control, the cleaning brush can be repeatedly rubbed on the tooth comb, thereby further improving the cleaning effect of the cleaning brush.

[0042] In some embodiments of the present application, a dust collection box is arranged in the shell and located below the cleaning brush.

[0043] In the technical scheme, the dust collection box arranged in the shell is located below the cleaning brush, which plays an important role in collecting dust. When the cleaning brush cleans the filter screen, the dust, impurities and other pollutants falling from the surface of the filter screen fall into the dust collection box under the action of gravity, avoiding the scattering and accumulation of these pollutants in the indoor unit of the air conditioner, preventing secondary pollution. The setting of the dust collection box facilitates the user to clean it regularly. The user only needs to take out the dust collection box and pour out the dust in it, without the need for complex cleaning operation on the interior of the indoor unit of the air conditioner, thereby reducing the maintenance difficulty and workload of the user. At the same time, maintaining the clean environment of the interior of the indoor unit of the air conditioner helps to reduce the erosion and damage of dust to other components, prolongs the service life of the equipment, improves the overall reliability and stability of the indoor unit of the air conditioner, and ensures its long-term stable operation, thereby providing good indoor air conditioning service for the user.

[0044] In addition, the present application also provides an indoor unit of an air conditioner, which comprises:

[0045] A shell having an air conditioner air inlet at the top thereof;

[0046] An indoor heat exchanger arranged in the shell;

[0047] An indoor fan arranged in the shell; the indoor fan enables air flow to enter the shell through the air conditioner air inlet and to be input to the indoor environment after heat exchange through the indoor heat exchanger;

[0048] A filter module arranged in the shell, the filter module comprising:

[0049] A support frame;

[0050] A first synchronous roller rotatably connected to one end of the support frame;

[0051] A second synchronous roller is rotationally connected to the support frame at an end distal from the first synchronous roller;

[0052] Two synchronous belts are disposed around the first and second synchronous rollers and are spaced apart;

[0053] A filter screen is detachably connected to the two synchronous belts at both sides in the width direction of the filter screen;

[0054] A cleaning module is used to clean the filter screen.

[0055] In the technical solution, the air conditioner air inlet at the top of the shell provides a channel for air to enter the air conditioner indoor unit, so that indoor air can smoothly enter the subsequent processing flow. The indoor heat exchanger exchanges heat with air through refrigerant circulation in the shell to achieve refrigeration or heating effect and adjust indoor air temperature. The indoor fan drives air flow to enter the shell from the air inlet, and then outputs to the indoor after heat exchange by the heat exchanger, thereby ensuring the circulation power of the air and making the indoor temperature uniformly distributed and maintained at a set state. The support frame of the filter module provides stable support for each component. The first and second synchronous rollers provide a mounting basis for the synchronous belts. The synchronous belts can rotate under the action of the first and second synchronous rollers. The filter screen is detachably connected to the synchronous belts, and the filter screen moves together with the synchronous belts, so that the filter screen can move in a specific path and realize function switching at different positions. When the filter screen needs to be detached, replaced or maintained, the filter screen and the synchronous belts can be directly detached. The cleaning module does not need to be removed as a whole. This greatly facilitates the maintenance and management of the filter screen, improves the use efficiency of the filter screen and the flexibility of the overall filtering system, and ensures that the air conditioner indoor unit always has good air filtering effect during long-time operation, which helps to protect the indoor heat exchanger and the fan and other components, prolongs the service life thereof, and improves the overall performance and reliability of the air conditioner indoor unit.

[0072] In the following, the present application will be specifically described by exemplary embodiments. However, it should be understood that the elements, structures and features in one embodiment can also be beneficially combined into other embodiments without further description.

[0073] In the present application, the air conditioner indoor unit comprises a shell, an indoor heat exchanger and an indoor fan. The indoor heat exchanger and the indoor fan are arranged in the shell. The indoor air enters the shell and contacts the indoor heat exchanger, the indoor heat exchanger exchanges heat with the air, and the heat-exchanged air is output to the indoor under the action of the indoor fan, so as to realize the adjustment of the indoor temperature.

[0074] In the following, the embodiments of the present application will be described in detail with reference to the drawings.

[0075] Please refer to all the drawings, in a schematic embodiment of the air conditioner indoor unit, the air conditioner indoor unit comprises: a shell 100, the shell 100 top is provided with air conditioner air inlet, air conditioner air inlet is used for air passing and entering the shell 100.

[0076] In some embodiments, the air conditioner indoor unit comprises an indoor heat exchanger, and the indoor heat exchanger is arranged inside the shell 100. The indoor heat exchanger is a key component for heat exchange in the air conditioning system. In the refrigeration mode, the refrigerant evaporates in the heat exchanger and absorbs the heat of the surrounding air.

[0077] In some embodiments, the air conditioner indoor unit comprises an indoor fan, and the indoor fan is arranged inside the shell 100. The indoor fan makes the airflow input into the shell 100 through the air conditioner air inlet and input into the room after heat exchange through the indoor heat exchanger.

[0078] In some embodiments, the air conditioner indoor unit comprises a filter module, and the filter module is arranged inside the shell 100. The filter module can effectively intercept solid particles such as dust, pollen, hair and fibers in the air. The filter module can prevent dust and other impurities from entering the indoor heat exchanger. If dust accumulates on the surface of the heat exchanger, the heat exchange efficiency of the heat exchanger will be reduced. Because the dust layer forms a heat insulation layer, which hinders the exchange of heat, whether in the refrigeration mode or the heating mode, the performance of the air conditioner will be affected. And the filter module can also protect the indoor fan. When impurities in the air enter the fan, it may affect the rotational balance of the fan, increase the load of the fan motor, cause the fan to wear out, produce noise, and even cause the fan to fail. The filter module can effectively reduce this risk, prolong the service life of the fan and reduce the maintenance cost of the air conditioner.

[0079] In some embodiments, the filter module comprises a support frame 200, and the support frame 200 is arranged in the shell 100 and detachably arranged at the air conditioner air inlet.

[0080] In some embodiments, the filter module comprises two first synchronous wheels 300, two second synchronous wheels 400 and two synchronous belts 500. The two first synchronous wheels 300 are arranged in the axial direction and rotate synchronously, and the two first synchronous wheels 300 are rotatably connected to one end of the support frame 200. The two second synchronous wheels 400 are arranged in the axial direction and rotate synchronously, and the two second synchronous wheels 400 are rotatably connected to the end of the support frame 200 away from the first synchronous wheels 300. The synchronous belts 500 are respectively sleeved on the corresponding first synchronous wheels 300 and second synchronous wheels 400. The rotation of the first synchronous wheels 300 or the second synchronous wheels 400 can drive the rotation of the synchronous belts 500.

[0081] In some embodiments, the filter module comprises a filter screen 800, and the two sides of the filter screen 800 in the width direction are detachably connected to the two synchronous belts 500 respectively.

[0082] In some embodiments, the air conditioner indoor unit comprises a cleaning module for cleaning the filter screen 800.

[0083] Through the above scheme, the air conditioner air inlet at the top of the shell 100 provides a channel for air to enter the air conditioner indoor unit, allowing indoor air to smoothly enter the subsequent processing flow. The indoor heat exchanger exchanges heat with the air through refrigerant circulation in the shell 100, achieving refrigeration or heating effect to regulate the indoor air temperature. The indoor fan drives the airflow to enter the shell 100 from the air inlet, and then outputs to the indoor after heat exchange by the heat exchanger, ensuring the circulation power of the air, so that the indoor temperature is uniformly distributed and maintained at a set state. The support frame 200 of the filter module provides stable support for each component. The first synchronous pulley 300 and the second synchronous pulley 400 provide a mounting basis for the synchronous belt 500. The synchronous belt 500 can rotate under the action of the first synchronous pulley and the second synchronous pulley 400. The filter screen 800 is detachably connected to the synchronous belt 500, and the filter screen 800 moves together with the synchronous belt 500, so that the filter screen 800 can move in a specific path to realize function switching at different positions. When the filter screen 800 needs to be disassembled, replaced or maintained, the filter screen 800 can be directly disassembled with the synchronous belt 500. The cleaning module does not need to be disassembled as a whole. This greatly facilitates the maintenance and management of the filter screen 800, improves the use efficiency of the filter screen 800 and the flexibility of the overall filtering system, while ensuring that the air conditioner indoor unit always has good air filtering effect during long-time operation, which helps to protect the indoor heat exchanger and fan components, prolong their service life, and improve the overall performance and reliability of the air conditioner indoor unit.

[0084] In some embodiments, the filter screen 800 and the synchronous belt 500 are connected by a nylon snap. The filter screen 800 and the synchronous belt 500 are connected by a nylon snap, which has the advantages of convenience and repeatability. When the user needs to disassemble the filter screen 800 for cleaning or replacement, he or she does not need to use professional tools, but can simply separate the filter screen 800, which can be quickly aligned and attached during installation. This greatly reduces the difficulty and time cost of maintaining the filter screen 800, improves the convenience and experience of using the air conditioner indoor unit, and also encourages users to regularly maintain the filter screen 800, thereby ensuring the good running state of the air conditioning system.

[0085] In some embodiments, the nylon snap is also known as a magic tape. It includes two fixed strips and adhesive strips that can be adhered to each other. The fixed strip is fixed on the filter screen 800, and the adhesive strip is fixed on the synchronous belt 500. Or the fixed strip is fixed on the synchronous belt 500, and the adhesive strip is fixed on the filter screen 800.

[0086] In some embodiments, the filter screen 800 is connected with the synchronous belt 500 through an adhesive. The adhesive connection between the filter screen 800 and the synchronous belt 500 can provide a more secure connection effect. During the circulation movement of the synchronous belt 500 driving the filter screen 800, it can effectively prevent the filter screen 800 from accidentally falling off or displacing due to factors such as vibration and air flow impact, ensuring that the filter screen 800 is always in the correct working position and ensuring the continuity and stability of the filtering work. At the same time, the adhesive connection is relatively simple and low in cost, which helps to reduce the production cost and assembly difficulty of the air conditioner indoor unit and improve the production efficiency on the premise of ensuring the reliability of the connection. When maintenance is needed, the filter screen 800 can be directly torn off and then re-pasted after re-gluing.

[0087] Further, the adhesive can be a glue strip. The use of the glue strip not only reduces the material cost, but also allows the operator to easily operate without special tools or skills when installing and replacing the filter screen 800. In addition, the glue strip has good flexibility and can adapt to filter screens 800 of different shapes and sizes, ensuring the uniformity and reliability of the adhesive. The glue strip also shows good aging resistance during long-term use, reducing the frequency and cost of maintenance.

[0088] In some embodiments, a first deflection roller 600 is arranged between the two first synchronous rollers 300, and the two ends of the first deflection roller 600 are coaxially connected to the two first synchronous rollers 300, respectively. The two ends of the first deflection roller 600 are coaxially connected to the two first synchronous rollers 300, respectively, to form a fixed connection between the two first synchronous rollers 300, ensuring that the two first synchronous rollers 300 can rotate synchronously. When the filter screen 800 needs to be deflected and turned when moving to the first synchronous roller 300, the first deflection roller 600 can be used for auxiliary turning to avoid damage to the filter screen 800 due to bending.

[0089] In some embodiments, the surface of the first deflection roller 600 is designed with a material having a high friction coefficient to ensure that the filter screen 800 can move stably when passing through, avoiding slipping.

[0090] In some embodiments, a second deflection roller 700 is arranged between the two second synchronous rollers 400, and the two ends of the second deflection roller 700 are coaxially connected to the two second synchronous rollers 400, respectively. The two ends of the second deflection roller 700 are coaxially connected to the two second synchronous rollers 400, respectively, to form a fixed connection between the two second synchronous rollers 400, ensuring that the two second synchronous rollers 400 can rotate synchronously. When the filter screen 800 needs to be deflected and turned when moving to the second synchronous roller 400, the second deflection roller 700 can be used for auxiliary turning to avoid damage to the filter screen 800 due to bending.

[0091] In some embodiments, the surface of the second deflection roller 700 is designed with a material having a high friction coefficient to ensure that the filter screen 800 can move stably when passing through and avoid slipping.

[0092] Through the above scheme, the first deflection roller 600 ensures that the two first synchronous wheels 300 rotate synchronously. The second deflection roller 700 ensures that the two second synchronous wheels 400 rotate synchronously.

[0103] In some embodiments, a dust collection box 170 is arranged in the shell 100, and the dust collection box 170 is located below the cleaning brush 160. The dust collection box 170 arranged in the shell 100 is located below the cleaning brush 160, which plays an important role in collecting dust. When the cleaning brush 160 cleans the filter screen 800, the dust, impurities and other pollutants falling from the surface of the filter screen 800 fall into the dust collection box 170 under the action of gravity, avoiding the scattering and accumulation of these pollutants in the air conditioner indoor unit, preventing secondary pollution. The setting of the dust collection box 170 facilitates the user to clean it regularly, and the user only needs to take out the dust collection box 170 and pour out the dust in it, without the need for complex cleaning operation in the air conditioner indoor unit, thereby reducing the maintenance difficulty and workload of the user. At the same time, maintaining the clean environment of the air conditioner indoor unit helps to reduce the erosion and damage of dust to other components, prolongs the service life of the equipment, improves the overall reliability and stability of the air conditioner indoor unit, and ensures its long-term stable operation, thereby providing good indoor air conditioning service for the user.

[0104] In some embodiments, the dust collection box 170 is detachably connected to the shell 100. The dust collection box 170 can be easily taken out to pour out the dust.

[0105] Please refer to all the drawings. In addition, the application also provides an air conditioner indoor unit, which comprises a shell 100, and an air conditioner air inlet is formed at the top of the shell 100, and the air conditioner air inlet is used for air to pass through and enter the shell 100.

[0106] In some embodiments, the air conditioner indoor unit comprises an indoor heat exchanger, which is arranged inside the shell 100. The indoor heat exchanger is a key component for heat exchange in the air conditioning system. In the cooling mode, the refrigerant evaporates in the heat exchanger and absorbs the heat of the surrounding air.

[0107] In some embodiments, the air conditioner indoor unit comprises an indoor fan, which is arranged inside the shell 100; the indoor fan makes the airflow enter the shell 100 through the air conditioner air inlet and then enters the indoor unit after being heated by the indoor heat exchanger.

[0108] In some embodiments, the air conditioner indoor unit comprises a filter module, which is arranged inside the shell 100. The filter module can effectively intercept solid particles such as dust, pollen, hair, and fibers in the air. The filter module can prevent impurities such as dust from entering the indoor heat exchanger. If dust accumulates on the surface of the heat exchanger, it will reduce the heat exchange efficiency of the heat exchanger. Because the dust layer will form an insulating layer, hindering the exchange of heat, it will affect the performance of the air conditioner in both cooling and heating modes. In addition, the filter module can also protect the indoor fan. When impurities in the air enter the fan, it may affect the rotational balance of the fan, increase the load of the fan motor, cause the fan to wear out more quickly, produce noise, and even cause the fan to malfunction. The filter module can effectively reduce this risk, prolong the service life of the fan, and reduce the maintenance cost of the air conditioner.

[0109] In some embodiments, the filter module comprises a support frame 200; the support frame 200 is detachably arranged at the air conditioner air inlet.

[0110] In some embodiments, the filter module comprises a first synchronous roller, a second synchronous roller, and two synchronous belts 500. The first synchronous roller is rotatably connected to one end of the support frame 200. The second synchronous roller is rotatably connected to the end of the support frame 200 away from the first synchronous roller. The synchronous belts 500 are wound around the first synchronous roller and the second synchronous roller, and the two synchronous belts 500 are arranged at intervals.

[0111] In some embodiments, the filter module comprises a filter screen 800, and the two sides of the filter screen 800 in the width direction are detachably connected to the two synchronous belts 500, respectively.

[0112] In some embodiments, the air conditioner indoor unit comprises a cleaning module for cleaning the filter screen 800.

[0113] Through the above scheme, the air conditioner air inlet at the top of the shell 100 provides a channel for the indoor air to enter the air conditioner indoor unit, so that the indoor air can smoothly enter the subsequent processing flow. The indoor heat exchanger exchanges heat with the air in the shell 100 through refrigerant circulation to achieve refrigeration or heating effect, and adjust the indoor air temperature. The indoor fan drives the airflow to enter the shell 100 from the air inlet, and then outputs to the indoor after heat exchange by the heat exchanger, ensuring the circulation power of the air, so that the indoor temperature is uniformly distributed and maintained at the set state. The support frame 200 of the filter module provides stable support for each component. The first synchronous roller and the second synchronous roller provide a mounting basis for the synchronous belt 500. The synchronous belt 500 can rotate under the action of the first synchronous roller and the second synchronous roller. The filter screen 800 is detachably connected to the synchronous belt 500, and the filter screen 800 moves with the synchronous belt 500, so that the filter screen 800 can move in a specific path to realize function switching at different positions. When the filter screen 800 needs to be disassembled, replaced or maintained, the filter screen 800 and the synchronous belt 500 can be directly disassembled. The cleaning module does not need to be disassembled as a whole. Greatly facilitates the maintenance and management of the filter screen 800, improves the use efficiency of the filter screen 800 and the flexibility of the overall filtering system, and at the same time ensures that the air conditioner indoor unit always has good air filtering effect during long time running, which helps to protect the indoor heat exchanger and fan and other components, prolongs the service life, and improves the overall performance and reliability of the air conditioner indoor unit.
