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] Air conditioners typically contain filters to purify the air. Currently, with increasing demands for a healthy quality of life, the cleaning of air conditioner filters has become a pressing issue. If air conditioner filters are not cleaned regularly, they accumulate a large amount of dust and bacteria. This not only affects the air conditioner's efficiency and increases energy consumption, but may also negatively impact human health, such as causing respiratory illnesses.

[0004] Existing technologies include a method where a drive roller rotates the filter screen to clean it with a brush. However, since the drive roller moves the filter screen through friction, the filter screen can slip, preventing thorough cleaning. 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 conditioner indoor unit in which at least one of the driving roller and the driven roller is made of rubber, avoiding excessive compression and damage to the filter. Simultaneously, the high friction of the rubber material allows for better movement of the filter. Furthermore, the driving roller and the driven roller mesh with each other through a first gear segment and a second gear segment, ensuring synchronous rotation between them. This further ensures that both sides of the filter can be clamped and synchronously driven by the driving roller and the driven roller, ensuring that the cleaning brush can effectively clean the filter, achieving efficient and stable cleaning results, while extending the filter's lifespan and improving the performance and reliability of the air conditioner indoor unit.

[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 disposed inside the housing;

[0010] An indoor fan is disposed inside the housing; the indoor fan causes airflow to enter the housing through the air conditioner inlet, and after heat exchange via the indoor heat exchanger, it is introduced into the room;

[0011] A filter module, disposed within the housing, comprises:

[0012] The first steering rod is located at one end of the air conditioning inlet;

[0013] The second steering rod is located at the end of the air conditioning inlet that is furthest from the first steering rod;

[0014] The filter screen is ring-shaped and fitted with the first steering rod and the second steering rod;

[0015] Cleaning module, the cleaning module includes:

[0016] Active roller;

[0017] The driven roller and the driving roller hold the filter screen;

[0018] A first drive assembly drives the active roller to rotate;

[0019] A cleaning brush is positioned below the filter and is used to contact the filter.

[0020] Wherein, at least one of the driving roller and the driven roller is made of rubber;

[0021] The driving roller is provided with a first gear segment shaped like a gear; the driven roller is provided with a second gear segment shaped like a gear, and the first gear segment and the second gear segment mesh with each other.

[0022] In this technical solution, a first drive component drives the active roller to rotate. The active roller and the driven roller clamp the filter screen, thus rotating the filter screen. At least one of the active roller and the driven roller is made of rubber, which avoids excessive compression and damage to the filter screen. Furthermore, the high friction of rubber allows for better movement of the filter screen. In addition, the active roller and the driven roller mesh with each other through a first gear segment and a second gear segment, ensuring synchronous rotation between them. This further ensures that both sides of the filter screen are clamped and driven synchronously by the active roller and the driven roller, ensuring that the cleaning brush can effectively clean the filter screen, achieving efficient and stable cleaning results. This also extends the filter screen's lifespan and improves the performance and reliability of the air conditioner's indoor unit.

[0023] In some embodiments of this application, the first gear segment and the second gear segment clamp the filter screen.

[0024] In the technical solution, the active roller and the driven roller mesh with each other through the first gear segment and the second gear segment, which ensures that the active roller and the driven roller rotate synchronously. Furthermore, the shape of the first gear segment and the second gear segment can increase the friction between them and the filter screen, ensuring that the filter screen maintains stable operation throughout the cleaning process.

[0025] In some embodiments of this application, the first gear segment and the second gear segment are located away from the filter screen.

[0026] In this technical solution, the driving roller and the driven roller mesh with each other through a first gear segment and a second gear segment, ensuring synchronous rotation between them. The portions of the driving roller and the driven roller that hold the filter screen are normal cylindrical shapes to prevent damage to the filter screen and to extend its lifespan.

[0027] In some embodiments of this application, the first driving component includes a first driving member, which is used to drive the active roller to rotate.

[0028] In the technical solution, the first drive component includes a first drive element, which can provide stable power to the cleaning module, ensuring that the active roller can rotate at a set speed and direction, thereby driving the filter screen to move.

[0029] In some embodiments of this application, the first drive assembly further includes a first gear and a drive gear, wherein the first gear is fixedly connected to one end of the drive roller; the drive gear is fixed to the output shaft of the first drive member; and the drive gear meshes with the first gear.

[0030] In this technical solution, gear transmission has high transmission efficiency, which reduces power loss during transmission and ensures that the power of the first driving component can effectively act on the drive roller. Furthermore, the gear meshing structure is relatively compact, allowing the first driving component to be positioned below the drive roller, saving space in the front-to-back direction of the air conditioner. This facilitates a more rational layout of internal components, enabling the entire cleaning module to operate efficiently within a limited space. This, in turn, improves the overall performance of the air conditioning filtration system and maintains the filter in a good filtration and cleaning state.

[0031] In some embodiments of this application, the cleaning module further includes:

[0032] A toothed comb, wherein the toothed comb is disposed inside the housing;

[0033] The second drive component is used to drive the cleaning brush to rotate and contact the comb.

[0034] In this technical solution, the cleaning brush interacts with the comb as it rotates. The comb removes dust, hair, and other impurities adhering to the brush, preventing it from losing its cleaning effectiveness due to build-up of impurities. This effectively solves the problem of declining cleaning efficiency caused by self-contamination after prolonged use of traditional cleaning brushes, maintaining the efficient operation of the air conditioner indoor unit's filtration system.

[0035] In some embodiments of this application, the second drive component further includes a second gear connected to one end of the cleaning brush; the second gear meshes with the first gear.

[0036] In this technical solution, the first driving component drives the drive gear to rotate, and the rotation of the cleaning brush is achieved through the meshing of the second gear with the drive gear. A single first driving component can achieve the rotation of both the filter and the cleaning brush, saving costs.

[0037] In some embodiments of this application, the second driving component includes a second driving member, which is used to drive the cleaning brush to rotate.

[0038] In this technical solution, the second drive component in the second drive assembly can independently drive the cleaning brush to rotate, providing a power source for the coordinated action between the cleaning brush and the comb. The cleaning brush only rotates when needed. This ensures that the cleaning brush rotates at a predetermined speed and direction, making the combing action between it and the comb stable and reliable. A stable power supply guarantees the continuous cleaning effect of the cleaning brush during the filter cleaning process, preventing situations where insufficient or unstable power causes the cleaning brush to malfunction or produce poor cleaning results. This maintains the normal operation of the air conditioner indoor unit's filtration system, ensuring that the indoor air meets the expected purification standards after filtration, and improving the overall performance and reliability of the air conditioner indoor unit.

[0039] In some embodiments of this application, a dust collection box is further provided inside the housing, and the dust collection box is located below the cleaning brush.

[0040] In the technical solution, the dust collection box can effectively collect the dust and impurities brushed off by the cleaning brush, preventing dust from falling into the housing and affecting the internal components of the air conditioner, or preventing dust from falling back into the indoor environment, thus keeping the indoor air clean.

[0041] In addition, this application also provides an air conditioner indoor unit, which includes:

[0042] The casing has an air conditioning inlet at the top;

[0043] An indoor heat exchanger is disposed inside the housing;

[0044] An indoor fan is disposed inside the housing; the indoor fan causes airflow to enter the housing through the air conditioner inlet, and after heat exchange via the indoor heat exchanger, it is introduced into the room;

[0045] A filter module, disposed within the housing, comprises:

[0046] The first steering rod is located at one end of the air conditioning inlet;

[0047] The second steering rod is located at the end of the air conditioning inlet that is furthest from the first steering rod;

[0048] The filter screen is ring-shaped and fitted with the first steering rod and the second steering rod;

[0049] Cleaning module, the cleaning module includes:

[0050] The drive roller is gear-shaped;

[0051] The driven roller is gear-shaped, and the driven roller meshes with the driving roller to clamp the filter screen;

[0052] A first drive assembly drives the active roller to rotate;

[0053] A cleaning brush is positioned below the filter and is used to contact the filter.

[0054] At least one of the driving roller and the driven roller is made of rubber.

[0055] In this technical solution, a first drive component drives the active roller to rotate. The active roller and the driven roller clamp the filter screen, thus rotating the filter screen. At least one of the active roller and the driven roller is made of rubber, which avoids excessive compression and damage to the filter screen. Furthermore, the high friction of rubber allows for better movement of the filter screen. In addition, the active roller and the driven roller mesh with each other through a first gear segment and a second gear segment, ensuring synchronous rotation between them. This further ensures that both sides of the filter screen are clamped and driven synchronously by the active roller and the driven roller, ensuring that the cleaning brush can effectively clean the filter screen, achieving efficient and stable cleaning results. This also extends the filter screen's lifespan and improves the performance and reliability of the air conditioner's indoor unit.

[0074] In this application, the indoor unit of the air conditioner includes a casing, an indoor heat exchanger, and an indoor fan. The indoor heat exchanger and the indoor fan are disposed inside the casing. Indoor air enters the casing and comes into contact with the indoor heat exchanger. After heat exchange between the indoor heat exchanger and the air, the heat-exchanged air is output to the room under the action of the indoor fan, thereby achieving the regulation of the indoor temperature.

[0075] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0076] Please refer to all the accompanying drawings. In one illustrative embodiment of the indoor unit of the air conditioner of this utility model, the indoor unit includes: the indoor unit includes a housing 100, and an air conditioning air inlet is provided on the top of the housing 100 for air to pass through and enter the housing 100.

[0077] In some embodiments, the indoor unit of the air conditioner includes an indoor heat exchanger disposed inside the housing 100. The indoor heat exchanger is a key component for heat exchange in the air conditioning system. In cooling mode, refrigerant evaporates within the heat exchanger, absorbing heat from the surrounding air.

[0078] In some embodiments, the indoor unit of the air conditioner includes an indoor fan disposed inside the housing 100; the indoor fan causes airflow to enter the housing 100 through the air conditioner air inlet, and after heat exchange by the indoor heat exchanger, it is output to the room.

[0079] In some embodiments, the indoor unit of the air conditioner includes a filter module disposed within the housing 100. The filter module of the air conditioner is mainly used to purify the air entering the air conditioner and intercept impurities such as dust, pollen, and hair in the air, playing an important role in the normal operation of the air conditioner and the improvement of indoor air quality.

[0080] In some embodiments, the filter module includes a first steering rod 201, a second steering rod 202, and a filter screen 200. The first steering rod 201 is disposed within the housing 100 and located at one end of the air conditioning inlet. The second steering rod 202 is disposed within the housing 100 and located at the end of the air conditioning inlet away from the first steering rod 201. The filter screen 200 is annular and is fitted with the first steering rod 201 and the second steering rod 202. The first steering rod 201 and the second steering rod 202 located at both ends of the air conditioning inlet together provide support for the filter screen 200. The first steering rod 201 and the second steering rod 202 pull the two ends of the filter screen 200, allowing the annular filter screen 200 to be stretched and opened, maintaining a relatively flat and stable filtration plane, preventing the filter screen 200 from collapsing, wrinkling, or other phenomena, ensuring that air can pass through all parts of the filter screen 200 without obstruction, and maintaining a stable and efficient filtration effect.

[0081] In some embodiments, the indoor unit of the air conditioner includes a cleaning module disposed within the housing 100. The cleaning module is used to clean the filter 200. The cleaning module has multiple technical benefits, including improving cleaning efficiency, extending the lifespan of the filter 200, and improving air quality. It also maintains air conditioning performance, enhances user experience, and promotes environmental protection and energy conservation. These effects collectively bring users a more comfortable, healthy, and convenient air conditioning experience.

[0082] In some embodiments, the cleaning module includes an active roller 600, a driven roller 700, and a first drive assembly, wherein the driven roller 700 and the active roller 600 clamp the filter screen 200; and the first drive assembly drives the active roller 600 to rotate.

[0083] In some embodiments, the cleaning module further includes a cleaning brush 300, which is disposed below the filter 200 and is used to contact the filter 200.

[0084] In some embodiments, the driving roller 600 is provided with a first gear segment 601 in the shape of a gear; the driven roller 700 is provided with a second gear segment 701 in the shape of a gear, and the first gear segment 601 and the second gear segment 701 mesh with each other.

[0085] In some embodiments, the drive roller 600 is made of rubber. Alternatively, the driven roller 700 is made of rubber. Alternatively, both the drive roller 600 and the driven roller 700 are made of rubber.

[0086] Through the above scheme, the first drive component drives the active roller 600 to rotate, and the active roller 600 and the driven roller 700 clamp the filter screen 200, thereby driving the filter screen 200 to rotate. At least one of the active roller 600 and the driven roller 700 is made of rubber, which avoids excessive compression and damage to the filter screen 200. At the same time, the rubber material has a large friction, which can better drive the filter screen 200 to move. In addition, the active roller 600 and the driven roller 700 mesh with each other through the first gear segment 601 and the second gear segment 701, ensuring that the active roller 600 and the driven roller 700 rotate synchronously. This further ensures that both sides of the filter screen 200 can be clamped by the active roller 600 and the driven roller 700 and driven synchronously, ensuring that the cleaning brush 300 can clean the filter screen 200, achieving efficient and stable cleaning effect, while extending the service life of the filter screen 200 and improving the performance and reliability of the air conditioner indoor unit.

[0087] In some embodiments, the drive roller 600 is located below the filter screen 200. The driven roller 700 is located in the middle of the annular filter screen 200, that is, the driven roller 700 is located between the first steering rod 201 and the second steering rod 202. The drive roller 600 and the driven roller 700 clamp the lower half of the filter screen 200, and the rotation of the filter screen 200 is achieved by friction through the rotation of the drive roller 600.

[0088] In some embodiments, the first gear segment 601 and the second gear segment 701 clamp the filter screen 200. The driving roller 600 and the driven roller 700 mesh with each other through the first gear segment 601 and the second gear segment 701, ensuring synchronous rotation between the driving roller 600 and the driven roller 700. Furthermore, the shape of the first gear segment 601 and the second gear segment 701 can increase the friction with the filter screen 200, ensuring that the filter screen 200 maintains stable operation throughout the cleaning process.

[0089] In some embodiments, a first gear segment 601 is located on the driving roller 600 and at its center. A second gear segment 701 is located on the driven roller 700 and at its center. The driving roller 600 and the driven roller 700 mesh with the filter screen 200. The gear segment being located in the center ensures that the filter screen 200 is subjected to uniform force during clamping, preventing damage.

[0090] In some embodiments, the first gear segment 601 and the second gear segment 701 are located away from the filter screen 200. That is, the first gear segment 601 and the second gear segment 701 do not contact the filter screen 200. The driving roller 600 and the driven roller 700 mesh with each other through the first gear segment 601 and the second gear segment 701, ensuring synchronous rotation between the driving roller 600 and the driven roller 700. The portions of the driving roller 600 and the driven roller 700 that hold the filter screen 200 are normally cylindrical, preventing damage to the filter screen 200 and improving its lifespan.

[0091] In some embodiments, there are two first gear segments 601 on the driving roller 600, located at both ends of the driving roller 600. There are two second gear segments 701 on the driven roller 700, located at both ends of the driven roller 700. The filter screen 200 is located between the two first gear segments 601 of the driving roller 600 and between the two second gear segments 701 of the driven roller 700. This design ensures that the driving roller 600 and the driven roller 700 can rotate synchronously and in opposite directions. It also prevents the filter screen 200 from being clamped at the meshing point of the first gear segments 601 and the second gear segments 701, thus preventing the filter screen 200 from being crushed.

[0092] In some embodiments, the first drive assembly includes a first drive member 800, which drives the active roller 600 to rotate. The first drive assembly, including the first drive member 800, can provide stable power to the cleaning module, ensuring that the active roller 600 can rotate at a set speed and direction, thereby driving the filter 200 to move.

[0093] In some embodiments, the first drive assembly further includes a first gear 110 and a drive gear 900. The first gear 110 is fixedly connected to one end of the drive roller 600; the drive gear 900 is fixed to the output shaft of the first drive member 800; and the drive gear 900 meshes with the first gear 110. Gear transmission has high transmission efficiency, which can reduce power loss during transmission and ensure that the power of the first drive member 800 can effectively act on the drive roller 600. Furthermore, the gear meshing structure is relatively compact, and the first drive member 800 can be positioned below the drive roller 600, saving space in the front-to-back direction of the air conditioner. This facilitates the rational layout of various components inside the air conditioner, enabling the entire cleaning module to operate efficiently within a limited space, thereby improving the overall performance of the air conditioning filtration system and maintaining the filter 200 in a good filtration and cleaning state.

[0094] In some embodiments, the cleaning module further includes a comb 400 and a second drive assembly, the comb 400 being disposed inside the housing 100. The second drive assembly is used to drive the cleaning brush 300 to rotate and contact the comb 400. The cleaning brush 300 interacts with the comb 400 when it rotates. The comb 400 can comb away dust, hair, and other impurities adhering to the cleaning brush 300, preventing the cleaning brush 300 from losing its cleaning effect due to the accumulation of impurities. This effectively solves the problem of decreased cleaning efficiency of traditional cleaning brushes 300 due to their own contamination after prolonged use, maintaining the efficient operation of the air conditioning indoor unit's filtration system.

[0095] In some embodiments, the second drive assembly further includes a second gear 120 connected to one end of the cleaning brush 300; the second gear 120 meshes with the first gear 110. The first drive member 800 drives the drive gear 900 to rotate, and the rotation of the cleaning brush 300 is achieved through the meshing of the second gear 120 with the drive gear 900. A single first drive member 800 can achieve the rotation of both the filter 200 and the cleaning brush 300, saving costs. Furthermore, the meshing of the second gear 120 with the first gear 110 ensures that the rotation direction of the cleaning brush 300 is opposite to the rotation direction of the filter 200, thereby improving the cleaning force.

[0096] In some embodiments, the cleaning brush 300 is a cylindrical brush to ensure that the filter 200 can be cleaned while it is constantly rotating.

[0097] In some embodiments, the second gear 120 meshes with the drive gear 900. The drive gear 900 drives the cleaning brush 300 to rotate. The direct meshing of the second gear 120 and the drive gear 900 constitutes a single-stage transmission, improving transmission efficiency.

[0098] In some embodiments, when the second gear 120 meshes with the drive gear 900, if the first gear 110 and the second gear 120 are the same size, then the pitch circle diameter of the first gear 110 and the outer diameter of the drive roller 600 are ensured to be different. If the pitch circle diameter of the first gear 110 and the outer diameter of the drive roller 600 are the same, then the pitch circle diameters of the first gear 110 and the second gear 120 are ensured to be different. This ensures that a differential speed is formed between the cleaning brush 300 and the filter screen 200, ensuring that the cleaning brush 300 can clean the filter screen 200.

[0099] In some embodiments, the second drive assembly includes a second drive member for driving the cleaning brush 300 to rotate. The second drive member can independently drive the cleaning brush 300 to rotate, providing a power source for the interaction between the cleaning brush 300 and the comb 400. It only drives the cleaning brush 300 to rotate when needed. This ensures that the cleaning brush 300 can rotate at a predetermined speed and direction, making its combing action with the comb 400 stable and reliable. A stable power supply guarantees the continuous cleaning effect of the cleaning brush 300 during the filter 200 cleaning process, avoiding situations where the cleaning brush 300 cannot work properly or the cleaning effect is poor due to insufficient or unstable power. This maintains the normal operation of the air conditioner indoor unit's filtration system, ensuring that the indoor air meets the expected purification standards after being filtered by the filter 200, and improving the overall performance and reliability of the air conditioner indoor unit.

[0100] In some embodiments, the driven roller 700 is the first steering rod 201. That is, the driven roller 700 replaces the first steering rod 201. It can also be understood that the driven roller 700 and the first steering rod 201 are integrally formed into a structural component.

[0101] In some embodiments, a dust collection box 500 is also provided inside the housing 100, located below the cleaning brush 300. The dust collection box 500 can effectively collect the dust and impurities brushed off by the cleaning brush 300, preventing dust from falling into the housing 100 and affecting the internal components of the air conditioner, or preventing dust from falling back into the indoor environment, thus maintaining clean indoor air.

[0102] In addition, this application also provides an air conditioner indoor unit, which includes a housing 100, and an air conditioner air inlet is provided on the top of the housing 100 for air to pass through and enter the housing 100.

[0103] In some embodiments, the indoor unit of the air conditioner includes an indoor heat exchanger disposed inside the housing 100. The indoor heat exchanger is a key component for heat exchange in the air conditioning system. In cooling mode, refrigerant evaporates within the heat exchanger, absorbing heat from the surrounding air.

[0104] In some embodiments, the indoor unit of the air conditioner includes an indoor fan disposed inside the housing 100; the indoor fan causes airflow to enter the housing 100 through the air conditioner air inlet, and after heat exchange by the indoor heat exchanger, it is output to the room.

[0105] In some embodiments, the indoor unit of the air conditioner includes a filter module disposed within the housing 100. The filter module of the air conditioner is mainly used to purify the air entering the air conditioner and intercept impurities such as dust, pollen, and hair in the air, playing an important role in the normal operation of the air conditioner and the improvement of indoor air quality.

[0106] In some embodiments, the filter module includes a first steering rod 201, a second steering rod 202, and a filter screen 200. The first steering rod 201 is disposed within the housing 100 and located at one end of the air conditioning inlet. The second steering rod 202 is disposed within the housing 100 and located at the end of the air conditioning inlet away from the first steering rod 201. The filter screen 200 is annular and is fitted with the first steering rod 201 and the second steering rod 202. The first steering rod 201 and the second steering rod 202 located at both ends of the air conditioning inlet together provide support for the filter screen 200. The first steering rod 201 and the second steering rod 202 pull the two ends of the filter screen 200, allowing the annular filter screen 200 to be stretched and opened, maintaining a relatively flat and stable filtration plane, preventing the filter screen 200 from collapsing, wrinkling, or other phenomena, ensuring that air can pass through all parts of the filter screen 200 without obstruction, and maintaining a stable and efficient filtration effect.

[0107] In some embodiments, the indoor unit of the air conditioner includes a cleaning module disposed within the housing 100. The cleaning module is used to clean the filter 200. The cleaning module has multiple technical benefits, including improving cleaning efficiency, extending the lifespan of the filter 200, and improving air quality. It also maintains air conditioning performance, enhances user experience, and promotes environmental protection and energy conservation. These effects collectively bring users a more comfortable, healthy, and convenient air conditioning experience.

[0108] In some embodiments, the cleaning module includes an active roller 600, a driven roller 700, and a first drive assembly. The active roller 600 is gear-shaped, and the driven roller 700 is gear-shaped. The driven roller 700 and the active roller 600 clamp the filter screen 200. The first drive assembly drives the active roller 600 to rotate.

[0109] In some embodiments, the cleaning module further includes a cleaning brush 300, which is disposed below the filter 200 and is used to contact the filter 200.

[0110] In some embodiments, the driving roller 600 is provided with a first gear segment 601 in the shape of a gear; the driven roller 700 is provided with a second gear segment 701 in the shape of a gear, and the first gear segment 601 and the second gear segment 701 mesh with each other.

[0111] In some embodiments, the drive roller 600 is made of rubber. Alternatively, the driven roller 700 is made of rubber. Alternatively, both the drive roller 600 and the driven roller 700 are made of rubber.

[0112] Through the above scheme, the first drive component drives the active roller 600 to rotate, and the active roller 600 and the driven roller 700 clamp the filter screen 200, thereby driving the filter screen 200 to rotate. At least one of the active roller 600 and the driven roller 700 is made of rubber, which avoids excessive compression and damage to the filter screen 200. At the same time, the rubber material has a large friction, which can better drive the filter screen 200 to move. In addition, the active roller 600 and the driven roller 700 mesh with each other through the first gear segment 601 and the second gear segment 701, ensuring that the active roller 600 and the driven roller 700 rotate synchronously. This further ensures that both sides of the filter screen 200 can be clamped by the active roller 600 and the driven roller 700 and driven synchronously, ensuring that the cleaning brush 300 can clean the filter screen 200, achieving efficient and stable cleaning effect, while extending the service life of the filter screen 200 and improving the performance and reliability of the air conditioner indoor unit.
