During the long-term operation of the air conditioner, the dust in the air is mixed with bacteria, and the long-term humid environment inside the air conditioner makes it easy for a large number of bacteria to breed inside the air conditioner. Due to their characteristics, the cross-flow fan blades and evaporator parts are one of the hardest hit areas for the growth and retention of dust and bacteria. During the use of the air conditioner, these dust and bacteria may be diffused into the room along with the gas blown out by the cross-flow fan blades, reducing the health of the air conditioner.

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] In order to solve the problem in the prior art that the cleaning process of the evaporator component of the air conditioner is complicated and leads to low cleaning efficiency, the present invention provides an air conditioner indoor unit, an air conditioner and an air conditioner control method.

[0033] Please refer to Figures 1 to 7As shown, one aspect of the present invention provides an air-conditioning indoor unit, including an evaporator 20 and a cross-flow fan blade 21, and also includes a cleaning component 10, the cleaning component 10 is rotatably arranged between the evaporator 20 and the cross-flow fan blade 21, and the cleaning component 10 includes a first cleaning component 11 and a second cleaning component 12; wherein the first cleaning component 11 is movably in contact with the evaporator 20 and the cross-flow fan blade 21 respectively to clean the dust on the evaporator 20 and the cross-flow fan blade 21, and the second cleaning component 12 is respectively arranged toward the evaporator 20 and the cross-flow fan blade 21 to spray cleaning liquid to the evaporator 20 and the cross-flow fan blade 21 respectively.

[0034] According to one aspect of the technical solution of the present invention, by separately setting the first cleaning component 11 and the second cleaning component 12, it is possible to realize multi-level cleaning of the key air outlet components of the air conditioner indoor unit in sequence, thereby improving the stability of the operation of the air blades and the evaporator 20 of the air conditioner indoor unit, and greatly improving the air outlet quality. In addition, by using the first cleaning component 11 and the second cleaning component 12 in coordination, the evaporator 20 and the crossflow fan blade 21 of the air conditioner can be automatically cleaned and cleaned, reducing the need for manual maintenance, and improving the cleaning efficiency and the thoroughness of cleaning. Thus, the problem of low cleaning efficiency caused by the cumbersome process of cleaning the evaporator 20 components of the air conditioner in the prior art is solved. At the same time, the cleaning component 10 is rotatably arranged between the evaporator 20 and the crossflow fan blade 21, which means that it can cover most of the surfaces of these components, including those areas that are usually difficult to access, thereby ensuring the comprehensiveness of cleaning.

[0035] like Figures 5 to 7 As shown, the cleaning assembly 10 also includes a cleaning pipe 13, which is rotatably mounted on the angle frame 201 of the evaporator 20, and the first cleaning component 11 and the second cleaning component 12 are respectively arranged on the cleaning pipe 13; wherein the second cleaning component 12 includes a plurality of groups of nozzles 120 arranged at intervals along the circumferential direction of the cleaning pipe 13, and each group of nozzles 120 includes a plurality of nozzles 120 arranged at intervals along the extension direction of the cleaning pipe 13, for spraying cleaning liquid. Through the above arrangement, during the cleaning process, the cleaning pipe 13 can rotate to drive the plurality of groups of nozzles 120 thereon to dynamically spray the evaporator 20 and the crossflow fan blade 21 from different angles and orientations, thereby achieving a more comprehensive cleaning effect, reducing cleaning dead angles, and reducing the need for manual intervention. In addition, the distribution design of the nozzles 120 can ensure that the cleaning liquid is evenly covered on the surface of the evaporator 20 and the crossflow fan blade 21, avoiding the problem of insufficient or excessive local cleaning, and improving the cleaning efficiency and cleanliness.

[0036] Specifically, the first cleaning component 11 includes a plurality of extension members 110, and the plurality of extension members 110 are arranged at intervals along the circumferential direction of the cleaning pipe member 13. The plurality of extension members 110 are arranged one-to-one correspondingly to the plurality of groups of nozzles 120. One side of the plurality of extension members 110 is rotatably connected to the cleaning pipe member 13 through a rotating shaft 111 and covers a corresponding group of nozzles 120. The other side of the plurality of extension members 110 is provided with a brush 112 for contacting the evaporator 20 and the cross-flow fan blade 21 respectively.

[0037] Through the above arrangement, during the cleaning process, when the rotation speed of the cleaning pipe 13 gradually increases, under the action of centrifugal force, the multiple extensions 110 can rotate along the rotating shaft 111 to gradually open, so that when the multiple extensions 110 are opened to the preset position, the brushes 112 on the extensions 110 can effectively contact and clean the inner side of the evaporator 20 and the cross-flow fan blades 21. In addition, at this time, the multiple groups of nozzles 120 located under the multiple extensions 110 are exposed, and further, by supplying cleaning liquid into the cleaning pipe 13, the cleaning liquid can be sprayed 360 degrees to the evaporator 20 and the cross-flow fan blades 21 under the rotation of the cleaning component, and under the action of the brushes 112 on the multiple extensions 110, the air conditioner indoor unit is deeply cleaned, thereby improving the comprehensiveness and efficiency of cleaning. At the same time, the extension piece 110 covers the nozzle 120 in the closed state, which can prevent the cleaning liquid from escaping before reaching the cleaning surface, and prevent dust from blocking the nozzle 120, thereby ensuring the effective use of the cleaning liquid, reducing resource waste, and avoiding the impact of the cleaning liquid on non-cleaning areas.

[0038] In this embodiment, each extension member 110 is an arc plate structure, and the inner wall surfaces of the plurality of extension members 110 are respectively in contact with the outer wall surface of the cleaning pipe 13. In this way, the extension member 110 of the arc plate structure can flexibly adapt to the shape changes of the evaporator 20 and the cross flow fan blade 21 when it is unfolded and rotated, and can achieve effective contact and cleaning regardless of whether it is a flat surface or a curved surface, thereby enhancing the adaptability and flexibility of the cleaning component. It also helps to guide the spray direction of the cleaning liquid, ensuring that the sprayed cleaning liquid can act more directly on the area that needs to be cleaned, thereby improving the utilization rate and cleaning effect of the cleaning liquid. At the same time, it can better adapt to the cleaning pipe 13 to adapt to the spatial layout inside the air conditioner, making the overall structure of the cleaning component 10 more compact, which is conducive to saving valuable space inside the air conditioner and providing convenience for the arrangement of other components. Combined with the automatic rotation function of the cleaning component 10, the extension member 110 of the arc plate structure can perform all-round cleaning of the evaporator 20 and the cross flow fan blade 21 without manual intervention, thereby improving the automation level and maintenance efficiency of the indoor unit of the air conditioner.

[0039] like Figure 7As shown, the cleaning assembly 10 also includes a plurality of elastic members 14, and the plurality of elastic members 14 are respectively arranged in one-to-one correspondence with the plurality of extension members 110, one end of the elastic member 14 is connected to the extension member 110, and the other end of the elastic member 14 is connected to the cleaning pipe 13, so that the extension member 110 is movably arranged relative to the cleaning pipe 13. The above arrangement enables the extension member 110 to more flexibly adapt to the curved surface of the evaporator 20 and the crossflow fan blade 21 when the cleaning pipe 13 rotates, and even if it encounters protrusions or depressions on the surface, the brush 112 can maintain good contact, thereby improving the comprehensiveness and efficiency of cleaning. In addition, after the cleaning is completed, the cleaning pipe 13 gradually reduces the rotation speed, so that the extension member 110 is gradually closed under the pulling force of the elastic member 14 until it fits with the outer peripheral wall of the cleaning pipe 13 to return to the initial state.

[0040] In this embodiment, the elastic member 14 is a tension spring or other elastic member made of silicone rubber material. Other elastic structures can also be selected according to usage requirements and actual working conditions, as long as it can provide a restoring force to return to the original position after cleaning is completed.

[0041] like Figure 5 As shown, the air conditioner indoor unit further includes a supply component 30, which is connected to the cleaning component 10 to provide cleaning liquid to the second cleaning component 12. In this way, the cleaning liquid can be automatically delivered to the second cleaning component 12 without manual intervention, thereby realizing the automation of the cleaning process, simplifying the maintenance process, and improving the cleaning efficiency. The pressure and flow of the cleaning liquid are ensured, so that the nozzle 120 can effectively spray the cleaning liquid, thereby enhancing the cleaning effect, especially in the removal of stubborn stains.

[0042] Specifically, the supply assembly 30 includes a connector 31 and a connecting pipe 32; the connector 31 is provided with a mounting ear 310, which is used to connect to the angle bracket 201 of the evaporator 20, and one end of the cleaning pipe 13 is rotatably connected to the connector 31; one end of the connecting pipe 32 is connected to the cleaning pipe 13 through the connector 31, and the other end of the connecting pipe 32 is connected to an external device to supply cleaning liquid into the cleaning pipe 13. In the above arrangement, the mounting ear 310 on the connector 31 is connected to the angle bracket 201 of the evaporator 20, which provides a firm positioning of the cleaning assembly 10, ensures the stability and accuracy of the cleaning assembly 10 during the cleaning process, and avoids the reduction of the cleaning effect due to position offset. The rotatable connection between the cleaning pipe 13 and the connector 31 allows the cleaning pipe 13 to rotate freely during the cleaning process, enhances the flexibility of the cleaning assembly 10, and can clean the evaporator 20 and the crossflow fan blade 21 in all directions, thereby improving the comprehensiveness and effect of cleaning.

[0043] Preferably, the water source supplied to the second cleaning component 12 can be selected as condensed water from an air conditioner.

[0044] like Figure 4 As shown, the cleaning assembly 10 also includes a driving component 15, which is arranged on the angle bracket 201 of the evaporator 20, and one end of the cleaning pipe 13 is provided with a mounting recess 130, and the output shaft of the driving component 15 extends into the mounting recess 130 to be connected with the cleaning pipe 13 to drive the cleaning pipe 13 to rotate. In this embodiment, the driving component 15 is a stepper motor. In this way, the cleaning process can be optimized by accurately controlling the rotation speed and angle of the cleaning pipe 13 through the driving component 15, and the cleaning strength and range can be adjusted according to different pollution levels, so as to improve the efficiency and effect of cleaning. In addition, the driving component 15 is installed on the angle bracket 201 of the evaporator 20, and the space of the angle bracket 201 is used for arrangement, which avoids the need for additional space, helps to optimize the internal structure layout of the air conditioner indoor unit, and makes it more compact.

[0045] In this embodiment, the indoor unit of the air conditioner further includes a detection unit, which is arranged between the evaporator 20 and the crossflow blades 21, so as to detect the contamination degree of the evaporator 20 and the crossflow blades 21 respectively. Through the above arrangement, the detection unit can monitor the contamination degree of the evaporator 20 and the crossflow blades 21 in real time, and automatically judge when it is necessary to start the cleaning component 10 for cleaning through the set contamination threshold, thereby realizing intelligent maintenance management, reducing the frequency of manual inspection and maintenance, and improving maintenance efficiency. Moreover, based on the contamination degree information provided by the detection unit, the air conditioner can accurately control the start-up and cleaning intensity of the cleaning component 10, avoiding the problem of over-cleaning or under-cleaning, ensuring the cleaning effect, saving the use of cleaning fluid, and reducing maintenance costs.

[0046] According to another aspect of the present invention, an air conditioner is provided, comprising an air conditioner indoor unit and an air conditioner outdoor unit, wherein the air conditioner indoor unit is the air conditioner indoor unit mentioned above.

[0047] On the other hand, the technical solution of the present invention is applied, and the indoor unit of the air conditioner is integrated with a cleaning component 10, which can automatically clean the evaporator 20 and the crossflow fan blades 21, which can not only improve the cleaning efficiency and reduce the maintenance cycle, but also ensure the cleanliness of the air conditioner, extend the service life of the equipment, and improve the air quality and health. In addition, since the detection unit in the indoor unit of the air conditioner can monitor the pollution level and work in conjunction with the cleaning component 10, the air conditioner can achieve intelligent control and automatically adjust the cleaning mode according to the real-time changes in the pollution level without manual intervention, thereby improving the user experience. At the same time, the automation and intelligent control of the cleaning component 10 can reduce unnecessary energy consumption, such as reducing the use of cleaning fluid when the pollution level is low, which plays a positive role in energy saving and environmental protection. At the same time, efficient cleaning reduces the increase in energy consumption of the air conditioner due to dust accumulation, further improving the energy efficiency ratio.

[0048] According to another aspect of the present invention, there is provided an air conditioner control method, which is applicable to the air conditioner mentioned above, and the control method comprises: setting a first pollution level threshold and a second pollution level threshold; obtaining the actual pollution level of the evaporator 20 and the crossflow fan blades 21 detected by the detection unit; comparing the actual pollution level with the first pollution level threshold and the second pollution level threshold, respectively, so as to control the first cleaning component 11 and / or the second cleaning component 12 to clean the dust on the evaporator 20 and the crossflow fan blades 21 according to the comparison result; wherein the first pollution level threshold is less than the second pollution level threshold.

[0049] According to another aspect of the technical solution of the present invention, by setting two different pollution thresholds, the air conditioner can take cleaning measures of different degrees according to the actual pollution level. The first pollution threshold is used to trigger a lighter cleaning mode, such as starting only the first cleaning component 11 (physical cleaning), while the second pollution threshold is used to trigger a more thorough cleaning mode, including using the first cleaning component 11 (physical cleaning) and the second cleaning component 12 (spraying cleaning liquid) to achieve deep cleaning. In this way, unnecessary energy consumption is reduced, thereby optimizing resource utilization and improving economic benefits. At the same time, the need for manual maintenance by users is reduced, and the convenience of use is improved. Users do not need to worry about the timing and operation of air conditioner cleaning.

[0050] Specifically, when the actual pollution level is greater than or equal to the first pollution level threshold and less than the second pollution level threshold, the first cleaning component 11 is controlled to clean the evaporator 20 and the crossflow fan blades 21 respectively. In this way, when the pollution level is low, only the first cleaning component 11 is used for cleaning, which avoids the waste of cleaning liquid, while also reducing unnecessary energy consumption and improving resource utilization efficiency. It also enables precise control of the timing and intensity of cleaning, avoiding the problem of over-cleaning or under-cleaning, and ensuring that the cleanliness inside the air conditioner is always maintained in an ideal state.

[0051] Specifically, when the actual pollution level is greater than or equal to the second pollution level threshold, the first cleaning component 11 and the second cleaning component 12 are controlled to clean the evaporator 20 and the crossflow fan blades 21 respectively. In this way, when the second pollution level threshold is reached, it usually means that the dust and dirt on the evaporator 20 and the crossflow fan blades 21 are seriously accumulated. At this time, the first cleaning component 11 and the second cleaning component 12 can be used at the same time to achieve deep cleaning of the evaporator 20 and the crossflow fan blades 21, completely remove stubborn dirt, and ensure the cleanliness of the air conditioner. Through intelligent control, the deep cleaning mode is started only when necessary, which can reduce unnecessary energy consumption and the use of cleaning fluid, meet the requirements of energy saving and environmental protection, and thus improve the convenience of using the air conditioner.

[0052] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0053] The air conditioner indoor unit includes an evaporator 20 and a cross-flow fan blade 21, and also includes a cleaning component 10. The cleaning component 10 is rotatably arranged between the evaporator 20 and the cross-flow fan blade 21, and the cleaning component 10 includes a first cleaning component 11 and a second cleaning component 12; wherein the first cleaning component 11 is movably in contact with the evaporator 20 and the cross-flow fan blade 21 to clean the dust on the evaporator 20 and the cross-flow fan blade 21, and the second cleaning component 12 is arranged toward the evaporator 20 and the cross-flow fan blade 21 to spray cleaning liquid to the evaporator 20 and the cross-flow fan blade 21. In this way, by separately arranging the first cleaning component 11 and the second cleaning component 12, multi-level cleaning of the key air outlet components of the air conditioner indoor unit can be achieved in sequence, thereby improving the stability of the operation of the air conditioner indoor unit fan blade and the evaporator 20, and greatly improving the air outlet quality. Furthermore, by using the first cleaning component 11 and the second cleaning component 12 in coordination, the evaporator 20 and the crossflow blades 21 of the air conditioner can be automatically cleaned and cleaned, reducing the need for manual maintenance and improving the cleaning efficiency and thoroughness of cleaning. This solves the problem of low cleaning efficiency caused by the cumbersome process of cleaning the evaporator 20 of the air conditioner in the prior art. At the same time, the cleaning component 10 is rotatably arranged between the evaporator 20 and the crossflow blades 21, which means that it can cover most of the surfaces of these components, including those areas that are usually difficult to access, thereby ensuring comprehensive cleaning.
