Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioning equipment, in particular to an air conditioner indoor unit. BACKGROUND

[0002] Air conditioner refers to the air conditioner, which is a device for artificially adjusting and controlling the temperature, humidity, flow rate and other parameters of the air in the environment of a building or structure. In order to meet the needs of real life, some air conditioners have fresh air function, which can transmit outdoor air to indoor.

[0003] Air conditioners usually have filter screens that can filter and clean air. At present, with the increasing demand for healthy life quality, the cleaning problem of air conditioner filter screen has gradually been put on the agenda. If the air conditioner filter screen is not cleaned regularly, a large amount of dust and bacteria will accumulate, which not only affects the working efficiency of the air conditioner and increases energy consumption, but also may affect human health, such as causing respiratory diseases.

[0004] Therefore, the existing technology usually uses a cleaning module to clean the filter screen. The cleaning module includes a cleaning brush, which abuts against the filter screen to clean the filter screen.

[0005] However, in the prior art, the cleaning brush directly abuts against the filter screen, and the contact effect of the cleaning brush on the filter screen cannot be guaranteed during operation, resulting in poor cleaning effect. Utility model content

[0006] The utility model at least solves one of the technical problems in the related art to some extent.

[0007] Therefore, the present application aims to provide an air conditioner indoor unit. Due to the limitation of the cleaning plate, the filter screen can be ensured to contact the cleaning brush, avoiding the separation of the cleaning brush and the filter screen, so as to improve the cleaning effect of the filter screen. In addition, the cleaning plate and the cleaning brush hold the filter screen, and the clamping force can be preset, so as to improve the pressure and pressure of the cleaning brush on the filter screen, further improving the cleaning effect.

[0008] To achieve the above purpose, the utility model provides an air conditioner indoor unit, which comprises:

[0009] A shell is provided with an air conditioner air inlet at the top;

[0010] An indoor heat exchanger is arranged inside the shell;

[0011] An indoor fan is arranged inside the shell; the indoor fan makes the airflow input into the shell through the air conditioner air inlet and input into the room after heat exchange through the indoor heat exchanger;

[0012] A filter module is arranged in the shell, and the filter module comprises:

[0013] A first steering rod is arranged in the shell and located at one end of an air conditioner air inlet;

[0014] A second steering rod is arranged in the shell and located at an end of the air conditioner air inlet away from the first steering rod;

[0015] A filter screen is annular and sleeved on the first steering rod and the second steering rod;

[0016] A cleaning module is arranged in the shell; the cleaning module comprises:

[0017] A first driving assembly is used to drive the filter screen to rotate;

[0018] A cleaning brush is arranged below the filter screen;

[0019] A cleaning plate is arranged in a space formed by the filter screen, and the cleaning plate and the cleaning brush clamp the filter screen.

[0020] In the technical scheme, indoor air enters the shell through the air conditioner air inlet under the action of an indoor fan, and dust and other impurities in the air are filtered by the filter screen when passing through the air conditioner air inlet. The indoor heat exchanger and other components are protected, the indoor air quality is improved, the maintenance cost is reduced, and the service life of the equipment is prolonged. The filter screen is driven to rotate under the action of the first driving assembly, and the outer surface of the filter screen is cleaned by the cleaning brush at this time. Because the cleaning plate limits the filter screen, it can be ensured that the filter screen can be in contact with the cleaning brush, so that the cleaning brush and the filter screen are separated and cannot be cleaned, thereby improving the cleaning effect of the filter screen. The cleaning plate and the cleaning brush clamp the filter screen, and the clamping force can be preset, so as to improve the pressure and pressure of the cleaning brush on the filter screen, and further improve the cleaning effect.

[0021] In some embodiments of the application, a plane perpendicular to the axis of the first steering rod is defined as a reference plane, and the profile line of the cleaning plate close to the cleaning brush in the cross section intersected by the reference plane is a wavy line.

[0022] In the technical scheme, the wavy line shape design increases the contact area and the diversity of the contact form between the cleaning plate and the filter screen. During the rotation of the filter screen, the cleaning plate with a wavy line shape can more effectively scrape the surface of the filter screen, remove dust and dirt attached at different positions and depths, and significantly improve the thoroughness and cleaning efficiency of the filter screen compared with a flat cleaning plate. The filter screen can maintain better filtering performance, thereby ensuring that the air purification effect of the air conditioner indoor unit is stable and efficient.

[0023] In some embodiments of the present application, the included angle between the tangent line of the contact between the cleaning brush and the cleaning plate and the tangent line of the cleaning brush at the contact between the cleaning brush and the cleaning plate is α, and α is 0-30°.

[0024] In the technical solution, the angle range can ensure that the cleaning brush forms a suitable contact angle with the filter screen surface during operation. When α is within the range, the cleaning brush can ensure full contact between the bristles and the filter screen during rotation to effectively remove dust and other impurities on the filter screen, and can also avoid excessive wear of the filter screen or incomplete cleaning caused by an excessively large or small angle. Moreover, the resistance of the cleaning brush entering the bottom range of the cleaning plate is reduced at the angle.

[0025] In some embodiments of the present application, the side of the cleaning plate facing the cleaning brush is provided with a circular arc surface, and the wavy line is located on the circular arc surface, and the axis of the circular arc surface is collinear with the axis of the cleaning brush.

[0026] In the technical solution, the side of the cleaning plate facing the cleaning brush is provided with a circular arc surface, and the axis of the circular arc surface is collinear with the axis of the cleaning brush. This design makes the shape and motion trajectory of the cleaning plate and the cleaning brush highly adaptive. When the cleaning brush rotates to clean the filter screen, the circular arc surface of the cleaning plate can closely fit the motion path of the brush to form stable and uniform support and cleaning effects on the filter screen. On the one hand, it can prevent the problems of cleaning blind areas or local excessive cleaning caused by the inconsistency between the motion trajectory of the cleaning plate and the brush, and ensure that the filter screen can be effectively cleaned everywhere. On the other hand, the collinear axis design makes the force distribution between the cleaning plate and the brush more uniform during cleaning, reduces the possible wear and vibration of the components caused by uneven force, improves the overall stability and reliability of the cleaning module, helps to maintain the stable performance of the air conditioner indoor unit, and improves the user experience.

[0027] In some embodiments of the present application, the cleaning plate comprises a plurality of concave teeth, and the plurality of concave teeth are arranged in a wavy shape on the side of the cleaning plate facing the cleaning brush.

[0028] Each of the concave teeth has a reference surface facing the approaching and contacting of the bristles of the cleaning brush, and each reference line is a line from the end of the reference surface away from the cleaning brush to the axis of the cleaning brush, and the minimum included angle between each reference line and the corresponding reference surface is β, and 10°<β<80°.

[0029] In the technical scheme, the angle range enables the concave teeth to better guide the movement direction of the brush when cooperating with the brush for cleaning, enhances the cleaning strength of the brush on the filter screen, makes the cleaning effect of the cleaning brush on the filter screen more accurate and efficient, thereby improving the cleaning performance of the entire filter module, ensuring the air purification effect of the air conditioner indoor unit to be stable and efficient, and providing better air quality for the indoor. In addition, under the size condition, the resistance of the cleaning brush, the filter screen and the cleaning plate is reduced, which is beneficial to the cleaning of the filter screen by the brush and avoids being stuck or jammed.

[0030] In some embodiments of the present application, the beta of the last concave tooth from the direction of the arrival of the cleaning brush is greater than 90 degrees.

[0031] In the technical scheme, the beta of the last concave tooth from the direction of the arrival of the cleaning brush is greater than 90 degrees. Such a design has a special effect during cleaning. When the cleaning brush first contacts the filter screen at the beginning of cleaning, the larger angle of the last concave tooth can act as a “guide shovel” to more effectively shovel some larger particles or thicker accumulated impurities on the filter screen, making the subsequent cleaning work of the cleaning brush easier to perform and improving the initial cleaning effect. Moreover, during the cleaning process, the concave tooth with the larger angle helps to guide the cleaned dust and other impurities in a specific direction, preventing the impurities from flying around or re-attaching to the cleaned parts in the cleaning area. In combination with components such as the dust collection box, the impurities can be more smoothly collected, the cleaning and filtering system of the entire air conditioner indoor unit is maintained, and the working efficiency and stability of the cleaning and filtering system of the entire air conditioner indoor unit are further improved.

[0032] In some embodiments of the present application, the first driving assembly comprises:

[0033] The driving brush has a peripheral wall abutting against the filter screen.

[0034] The first driving member drives the driving brush to rotate.

[0035] In the technical scheme, the filter screen is driven to rotate through the frictional contact between the driving brush and the filter screen. This driving method is simple, direct, stable and reliable, and can ensure that the filter screen rotates in a predetermined manner and speed during cleaning, so that each part of the filter screen can orderly pass through the cleaning area between the cleaning brush and the cleaning plate, achieving comprehensive cleaning of the filter screen, ensuring that the filter screen will not affect the overall filtering performance due to incomplete local cleaning, maintaining the stable air filtering efficiency of the air conditioner indoor unit and reducing the problem of increased energy consumption caused by filter screen blockage.

[0036] In some embodiments of the present application, a abutting plate is further included, and the abutting plate and the driving brush clamp the filter screen.

[0037] In the technical scheme, the abutting plate is added and clamps the filter screen with the driving brush, which further fixes the position of the filter screen during the cleaning process, preventing the filter screen from deviating or shaking when being driven to rotate by the driving brush. The stable position of the filter screen helps to improve the accuracy and consistency of the cleaning of the filter screen by the cleaning brush and the cleaning plate, avoids the situation of uneven cleaning or incomplete cleaning caused by unstable position of the filter screen, ensures that the filter screen is always in the best cleaning state during the whole working process, and further ensures the stable and reliable air filtering quality of the air conditioner indoor unit and improves the stability and reliability of the overall operation of the equipment. Moreover, the abutting plate can ensure that the filter screen can contact the cleaning brush, ensure that the filter screen can be driven, and ensure the stability of the rotation of the filter screen.

[0038] In some embodiments of the present application, the driving brush is cylindrical.

[0039] The abutting plate is curved, and the axis of the curved abutting plate is collinear with the driving brush.

[0040] In the technical scheme, the cylindrical driving brush can drive the filter screen to rotate with relatively constant friction, reducing the problem of excessive or insufficient local force on the filter screen caused by uneven contact, thereby prolonging the service life of the filter screen. The curved abutting plate is matched with the cylindrical driving brush, can better fit the shape of the filter screen, effectively clamps the filter screen from multiple directions, further improves the stability of the filter screen during the cleaning process, ensures the uniformity and consistency of the cleaning effect, and makes the air conditioner indoor unit always maintain good air filtering performance during long-term operation.

[0041] In some embodiments of the present application, the abutting plate is connected with the cleaning plate and is integrally formed.

[0042] In the technical scheme, the connection gap and connection structure between components are reduced, the possibility of accumulation of dust and other impurities at the connection is reduced, and the problems of affecting the cleaning effect or causing component corrosion and damage due to the accumulation of impurities are avoided. The integrally formed structure also improves the strength and stability of the overall structure, which can better withstand various forces during the rotation and cleaning of the filter screen, ensures that the clamping and cleaning effect of the cleaning plate and the abutting plate on the filter screen is always stable and effective, and is conducive to maintaining the long-term stable operation of the air filtering system of the air conditioner indoor unit, reducing the problems of increased maintenance cost and prolonged equipment downtime caused by component failure or performance degradation.

[0043] In some embodiments of the present application, a dust collecting box is arranged below the cleaning brush.

[0044] In the technical scheme, the dust box is used to collect dust and dirt and other impurities falling from the filter screen during the cleaning process. Timely collection of dust can prevent it from flying again in the shell, avoid secondary pollution to the cleaned filter screen and other components, and ensure the cleanliness of the indoor air conditioner. At the same time, the existence of the dust box also facilitates regular cleaning of dust, simplifies the maintenance operation process, improves the maintenance efficiency, makes the maintenance work of the indoor air conditioner more convenient and efficient, helps to maintain the stability and reliability of the overall performance of the equipment, prolongs the service life of the equipment and improves the user experience.

[0045] In some embodiments of the present application, the cleaning module further comprises:

[0046] The tooth comb;

[0047] The second driving assembly is used to drive the cleaning brush to rotate and contact with the tooth comb.

[0048] In the technical scheme, the cleaning brush rotates and interacts with the tooth comb. The tooth comb can comb the dust and hair and other impurities attached to the cleaning brush, preventing the cleaning brush from losing its cleaning effect due to the accumulation of impurities. By driving the cleaning brush to rotate with the tooth comb through the second driving assembly, the cleaning brush can always maintain good cleaning ability during the cleaning process of the filter screen, ensuring the cleaning effect of the filter screen is stable and effective, effectively solving the problem of traditional cleaning brushes that lose cleaning efficiency after long-term use due to self-pollution, maintaining the efficient operation of the air conditioner indoor machine filter system, and ensuring the continuous improvement of indoor air quality.

[0049] In some embodiments of the present application, the second driving assembly comprises a second driving member for driving the cleaning brush to rotate.

[0050] In the technical scheme, the second driving member in the second driving assembly is used to drive the cleaning brush to rotate, providing a power source for the coordinated action of the cleaning brush and the tooth comb, ensuring that the cleaning brush can rotate at a predetermined speed and direction, and making the combing action between the cleaning brush and the tooth comb stable and reliable. Stable power supply ensures the cleaning effect of the cleaning brush during the cleaning process of the filter screen, avoiding the situation that the cleaning brush cannot work normally or the cleaning effect is poor due to insufficient or unstable power, thereby maintaining the normal operation of the air conditioner indoor machine filter system, ensuring that the indoor air filtered by the filter screen can meet the expected purification standard, and improving the overall performance and reliability of the air conditioner indoor machine.

[0051] In addition, the present application provides an indoor air conditioner, which comprises:

[0052] The shell has an air conditioner air inlet at the top;

[0053] The indoor heat exchanger is arranged inside the shell;

[0054] An indoor fan is arranged inside the shell; the indoor fan makes air flow through the air conditioner air inlet into the shell and is input to the indoor through the indoor heat exchanger after heat exchange;

[0055] A filter module is arranged in the shell, and the filter module comprises:

[0056] A first steering rod is arranged in the shell and located at one end of the air conditioner air inlet;

[0057] A second steering rod is arranged in the shell and located at one end of the air conditioner air inlet away from the first steering rod;

[0058] A filter screen is annular and sleeved on the first steering rod and the second steering rod;

[0059] A cleaning module is arranged in the shell; the cleaning module comprises:

[0061] A cleaning brush is arranged on the outer peripheral wall of the filter screen;

[0062] A cleaning plate is arranged inside the filter screen, and the cleaning plate and the cleaning brush clamp the filter screen.

[0063] In the technical scheme, indoor air enters the shell through the air conditioner air inlet under the action of the indoor fan, and dust and impurities in the air are filtered by the filter screen when passing through the air conditioner air inlet. The indoor heat exchanger and other components are protected, the indoor air quality is improved, the maintenance cost is reduced, and the service life of the equipment is prolonged. The filter screen is driven to rotate under the action of the first driving assembly, and the outer surface of the filter screen is cleaned by the cleaning brush. Because the cleaning plate limits the filter screen, the filter screen can be in contact with the cleaning brush, so that the cleaning brush and the filter screen are not separated and cannot be cleaned, thereby improving the cleaning effect of the filter screen. The cleaning plate and the cleaning brush clamp the filter screen, and the clamping force can be preset, so that the pressure and pressure of the cleaning brush on the filter screen are improved, and the cleaning effect is further improved.

[0082] The utility model will be described in detail below through exemplary embodiments. However, it should be understood that the elements, structures and features in one embodiment can also be beneficially incorporated into other embodiments without further elaboration.

[0083] In this application, the air conditioner indoor unit includes a housing, an indoor heat exchanger and an indoor fan. The indoor heat exchanger and the indoor fan are arranged in the housing. The indoor air enters the housing and contacts the indoor heat exchanger. After the indoor heat exchanger exchanges heat with the air, the indoor fan outputs the heat-exchanged air to the indoor to regulate the indoor temperature.

[0084] In the following, the embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0085] Please refer to all the drawings. In one exemplary embodiment of the utility model air conditioner indoor unit, the air conditioner indoor unit includes a housing 100, the housing 100 top is provided with air conditioner air inlet, the air conditioner air inlet is used for air passing and entering the housing 100.

[0086] In some embodiments, the air conditioner indoor unit includes an indoor heat exchanger arranged inside the housing 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.

[0087] In some embodiments, the air conditioner indoor unit includes an indoor fan arranged inside the housing 100; the indoor fan makes the airflow input into the housing 100 through the air conditioner air inlet and input into the indoor after heat exchange through the indoor heat exchanger.

[0088] In some embodiments, the air conditioner indoor unit includes a filter module arranged in the housing 100. The filter module of the air conditioner is mainly used to purify the air entering the interior of the air conditioner, intercepting dust, pollen, hair and other impurities in the air, playing an important role in the normal operation of the air conditioner and the improvement of indoor air quality.

[0089] In some embodiments, the filtering module includes a first turning rod 300, a second turning rod 400, and a filter screen 210. The first turning rod 300 is arranged in the shell 100 and located at one end of the air conditioner air inlet. The second turning rod 400 is arranged in the shell 100 and located at the end of the air conditioner air inlet away from the first turning rod 300. The filter screen 210 is annular and sleeved on the first turning rod 300 and the second turning rod 400. The first turning rod 300 and the second turning rod 400 located at both ends of the air conditioner air inlet jointly support the filter screen 210. The first turning rod 300 and the second turning rod 400 pull both ends of the filter screen 210, so that the annular filter screen 210 can be stretched straight and kept in a relatively flat and stable filtering plane, preventing the filter screen 210 from collapsing or wrinkling, and ensuring that air can pass through each part of the filter screen 210 without obstruction, thereby maintaining stable and efficient filtering effect.

[0090] In some embodiments, the air conditioner indoor unit includes a cleaning module arranged in the shell 100. The cleaning module has multiple technical effects, which can not only improve cleaning efficiency, prolong the service life of the filter screen 210, and improve air quality, but also maintain air conditioner performance, enhance user experience, and promote environmental protection and energy saving. These effects collectively bring users a more comfortable, healthy, and convenient air conditioner use experience.

[0091] In some embodiments, the cleaning module includes a first driving assembly, a cleaning brush 170, and a cleaning plate 500. The first driving assembly is used to drive the filter screen 210 to rotate. The cleaning brush 170 is arranged below the filter screen 210. The cleaning plate 500 is arranged in the space formed by the filter screen 210, and the cleaning plate 500 and the cleaning brush 170 clamp the filter screen 210.

[0092] In the above-mentioned scheme, indoor air enters the shell 100 through the air conditioner air inlet under the action of the indoor fan, and dust and other impurities in the air are filtered by the filter screen 210 when passing through the air conditioner air inlet. The indoor heat exchanger and other components are protected, and the indoor air quality is improved, reducing maintenance costs and prolonging the service life of the equipment. The filter screen 210 is driven to rotate under the action of the first driving assembly, and the outer surface of the filter screen 210 is cleaned by the cleaning brush 170 at this time. Because of the limitation of the cleaning plate 500, it can be ensured that the filter screen 210 can contact the cleaning brush 170, avoiding the separation of the cleaning brush 170 and the filter screen 210, which can improve the cleaning effect of the filter screen 210. And the cleaning plate 500 and the cleaning brush 170 clamp the filter screen 210, and the clamping force can be preset, so as to improve the pressure and pressure of the cleaning brush 170 on the filter screen 210, further improving the cleaning effect.

[0093] In some embodiments, a plane perpendicular to the axis of the first steering rod 300 is defined as a reference plane, and the profile line of the cross section of the cleaning plate 500 cut by the reference plane close to the cleaning brush 170 is a wavy line. This wavy line shape design increases the contact area and the variety of contact forms between the cleaning plate 500 and the filter screen 210. During the rotation of the filter screen 210, the wavy line shaped cleaning plate 500 can more effectively scrape the surface of the filter screen 210 to remove dust and dirt attached in different positions and depths, and can significantly improve the thoroughness and cleaning efficiency of the filter screen 210 compared with the flat cleaning plate 500, so as to keep the filter screen 210 in better filtering performance, thereby ensuring the stable and efficient air purification effect of the air conditioner indoor unit.

[0094] In some embodiments, the side wall of the cleaning plate 500 facing the cleaning brush 170 is arranged up and down in the length direction of the shell 100.

[0095] In some embodiments, the included angle between the tangent line of the cleaning brush 170 and the tangent line of the cleaning plate 500 contacting the cleaning brush 170 is α, and α = 0 ~ 30°. This angle range can ensure that the cleaning brush 170 forms a suitable contact angle with the surface of the filter screen 210 during work. When α is within this range, the cleaning brush 170 can ensure full contact between the bristles and the filter screen 210 during rotation to effectively remove dust and other impurities on the filter screen 210, and can also avoid excessive wear or incomplete cleaning of the filter screen 210 due to an excessively large or small angle. And at this angle, the resistance of the cleaning brush 170 entering the range at the bottom of the cleaning plate 500 is reduced.

[0096] In some embodiments, the side of the cleaning plate 500 facing the cleaning brush 170 is arranged as a circular arc surface, and the wavy line is located on the circular arc surface, and the axis of the circular arc surface is collinear with the axis of the cleaning brush 170. The side of the cleaning plate 500 facing the cleaning brush 170 is arranged as a circular arc surface, and the axis of the circular arc surface is collinear with the axis of the cleaning brush 170. This design makes the shape and motion trajectory of the cleaning plate 500 and the cleaning brush 170 highly adaptive. When the cleaning brush 170 rotates to clean the filter screen 210, the circular arc surface of the cleaning plate 500 can closely fit the motion path of the brush to form stable and uniform support and cleaning effect on the filter screen 210. On the one hand, it can prevent the problems of cleaning blind area or local excessive cleaning caused by the inconsistency between the cleaning plate 500 and the motion trajectory of the brush, and ensure that the filter screen 210 can be effectively cleaned everywhere; on the other hand, the collinear axis design makes the force distribution between the cleaning plate 500 and the brush more uniform during cleaning, reduces the possible component wear and vibration caused by uneven force, improves the overall stability and reliability of the cleaning module, helps to maintain the stable performance of the air conditioner indoor unit, and improves the user's experience.

[0097] In some embodiments, the cleaning plate 500 comprises a plurality of concave teeth, which are wavy on the side of the cleaning plate 500 facing the cleaning brush 170. The face of each concave tooth facing the bristles of the cleaning brush 170 is a reference face; the reference line is the line from the end of the reference face away from the cleaning brush 170 to the axis of the cleaning brush 170, and the minimum angle between each reference line and the corresponding reference face is β; 10°<β<80°. This angle range allows the concave teeth to better guide the movement direction of the bristles when cooperating with the cleaning brush, thereby enhancing the cleaning strength of the bristles on the filter screen 210, making the cleaning effect of the cleaning brush 170 on the filter screen 210 more precise and efficient, thereby improving the cleaning performance of the entire filter module and ensuring the air purification effect of the air conditioner indoor unit to be stable and efficient, thereby providing better air quality for the indoor environment. Moreover, under this size condition, the resistance of the cleaning brush 170, the filter screen 210 and the cleaning plate 500 is reduced, which is conducive to the cleaning of the filter screen 210 by the cleaning brush and avoids being stuck or jammed.

[0098] In some embodiments, the β of the last concave tooth from the direction of the arrival of the cleaning brush 170 is greater than 90°. The β of the last concave tooth from the direction of the arrival of the cleaning brush 170 is greater than 90°, which has a special effect during cleaning. When the cleaning brush 170 first contacts the filter screen 210 at the beginning of cleaning, the larger angle of the last concave tooth can act like a "guide shovel" to more effectively shovel some larger particles or thicker accumulated impurities on the filter screen 210, making the subsequent cleaning work of the cleaning brush 170 easier to perform and improving the initial cleaning effect. Moreover, during cleaning, the concave tooth with a larger angle helps to guide the cleaned dust and other impurities in a specific direction, preventing the impurities from flying around or re-attaching to the cleaned parts in the cleaning area, and cooperating with components such as the dust collecting box 190 to make it easier for the impurities to be collected, thereby maintaining the cleanliness of the air conditioner interior environment and further improving the cleaning and filtering system efficiency and stability of the entire air conditioner indoor unit.

[0099] In some embodiments, the size of the interference between the cleaning brush 170 and the concave teeth of the cleaning plate 500 is A, the tooth height of the concave teeth is B, and A≤B is ensured.
