Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more specifically, to an indoor air conditioner unit, an air conditioner, and an air conditioner control method. Background Technology

[0002] Currently, with the development of the times, air conditioners that only provide cooling and heating can no longer meet customer needs; healthy air has also become an important factor for users when making choices. Split-type air conditioners are widely used due to their small footprint and ease of installation and maintenance. However, during long-term operation, dust and bacteria in the air, combined with the consistently humid environment inside the air conditioner, easily lead to the growth of large amounts of bacteria. The cross-flow fan blades and evaporator components, due to their characteristics, are among the most problematic areas for dust and bacteria growth and retention. These dust and bacteria may be dispersed into the room along with the air blown out by the cross-flow fan during air conditioner use, reducing the health benefits of the air conditioner.

[0003] However, most current solutions to this problem involve regularly cleaning the inside of the air conditioner, disassembling and cleaning the evaporator components, or simply cleaning the cross-flow fan blades. This limits the cleaning area and makes cleaning multiple components quite troublesome. Furthermore, manual disassembly and reassembly, as well as washing the fan blades directly with a brush or water from the outside, all result in tedious cleaning, difficulty for non-professionals to operate, and difficulty in achieving thorough cleaning, leading to low cleaning efficiency. Summary of the Invention

[0004] The main objective of this invention is to provide an indoor air conditioning unit, an air conditioner, and an air conditioning control method to solve the problem that the cleaning process for the evaporator components of an air conditioner is cumbersome and results in low cleaning efficiency in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, an air conditioning indoor unit is provided, including an evaporator and a cross-flow fan blade. The air conditioning indoor unit further includes a cleaning assembly rotatably disposed between the evaporator and the cross-flow fan blade. The cleaning assembly includes a first cleaning component and a second cleaning component. The first cleaning component is movably contacted with the evaporator and the cross-flow fan blade respectively to clean dust on the evaporator and the cross-flow fan blade. The second cleaning component is disposed towards the evaporator and the cross-flow fan blade respectively to spray cleaning liquid onto the evaporator and the cross-flow fan blade respectively.

[0006] Furthermore, the cleaning assembly also includes: a cleaning pipe rotatably mounted on an angled bracket of the evaporator, with a first cleaning component and a second cleaning component respectively disposed on the cleaning pipe; wherein the second cleaning component includes multiple sets of nozzles spaced apart along the circumferential direction of the cleaning pipe, each set of nozzles including multiple nozzles spaced apart along the extension direction of the cleaning pipe for spraying cleaning fluid.

[0007] Furthermore, the first cleaning component includes: multiple extension members, spaced apart along the circumferential direction of the cleaning pipe, with each extension member corresponding to a set of nozzles, one side of each extension member being rotatably connected to the cleaning pipe via a rotating shaft and covering the corresponding set of nozzles, and the other side of each extension member being provided with a brush for contacting the evaporator and the cross-flow fan blades respectively.

[0008] Furthermore, each extension component is an arc-shaped plate structure, and the inner wall surface of multiple extension components respectively mates and contacts the outer wall surface of the cleaning pipe.

[0009] Furthermore, the cleaning assembly also includes: multiple elastic members, each corresponding to a multiple extension members, with one end of the elastic member connected to the extension member and the other end of the elastic member connected to the cleaning tube, so that the extension member is movable relative to the cleaning tube.

[0010] Furthermore, the indoor unit of the air conditioner also includes a supply component connected to the cleaning component for supplying cleaning fluid to the second cleaning component.

[0011] Furthermore, the supply component includes: a connector having mounting ears for connecting to the angle bracket of the evaporator, one end of the cleaning pipe being rotatably connected to the connector; and a connecting pipe having one end connected to the cleaning pipe via the connector, and the other end connected to an external device for supplying cleaning fluid into the cleaning pipe.

[0012] Furthermore, the cleaning assembly also includes: a drive component, which is mounted on the angle bracket of the evaporator, and a mounting recess is provided at one end of the cleaning pipe. The output shaft of the drive component extends into the mounting recess to drive the cleaning pipe to rotate.

[0013] Furthermore, the indoor unit of the air conditioner also includes a detection unit, which is located between the evaporator and the cross-flow fan blades, for detecting the contamination level of the evaporator and the cross-flow fan blades respectively.

[0014] According to another aspect of the present invention, an air conditioner is provided, comprising an indoor unit and an outdoor unit, wherein the indoor unit is the aforementioned indoor unit.

[0015] According to another aspect of the present invention, an air conditioner control method is provided, applicable to the aforementioned air conditioner. The control method includes: setting a first pollution degree threshold and a second pollution degree threshold; obtaining the actual pollution degree of the evaporator and cross-flow fan blades detected by a detection unit; comparing the actual pollution degree with the first pollution degree threshold and the second pollution degree threshold respectively, so as to control a first cleaning component and / or a second cleaning component to clean the dust on the evaporator and cross-flow fan blades according to the comparison result; wherein the first pollution degree threshold is less than the second pollution degree threshold.

[0016] Furthermore, based on the comparison results, the first cleaning component and / or the second cleaning component are controlled to clean the dust on the evaporator and the cross-flow fan blades, including: when the actual contamination level is greater than or equal to the first contamination level threshold and less than the second contamination level threshold, the first cleaning component is controlled to clean the evaporator and the cross-flow fan blades respectively; and / or, when the actual contamination level is greater than or equal to the second contamination level threshold, the first cleaning component and the second cleaning component are controlled to clean the evaporator and the cross-flow fan blades respectively.

The cleaning assembly is rotatably disposed between the evaporator and the cross-flow fan, and includes a first cleaning component and a second cleaning component. The first cleaning component is movably in contact with the evaporator and the cross-flow fan to clean dust from the evaporator and the cross-flow fan, and the second cleaning component is disposed toward the evaporator and the cross-flow fan to spray cleaning fluid onto the evaporator and the cross-flow fan.

[0018] In this way, by independently setting up the first and second cleaning components, multi-level cleaning of key air outlet components of the air conditioner's indoor unit can be achieved sequentially, improving the operational stability of the indoor unit's fan blades and evaporator, and significantly enhancing airflow quality. Furthermore, the combined use of the first and second cleaning components allows for automatic cleaning of the evaporator and cross-flow fan blades, reducing the need for manual maintenance and improving cleaning efficiency and thoroughness. This solves the problem of low cleaning efficiency due to the cumbersome process of cleaning the evaporator components in existing technologies. Simultaneously, the cleaning assembly is rotatably positioned between the evaporator and cross-flow fan blades, meaning it can cover most surfaces of these components, including areas that are normally difficult to reach, thus ensuring comprehensive cleaning.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] To address the problem of low cleaning efficiency caused by the cumbersome process of cleaning the evaporator components of air conditioners in existing technologies, this invention provides an indoor air conditioner 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 indoor air conditioning unit, including an evaporator 20 and a cross-flow fan blade 21, and further including a cleaning assembly 10. The cleaning assembly 10 is rotatably disposed between the evaporator 20 and the cross-flow fan blade 21. The cleaning assembly 10 includes a first cleaning component 11 and a second cleaning component 12. The first cleaning component 11 is movably in contact with the evaporator 20 and the cross-flow fan blade 21 respectively to clean dust on the evaporator 20 and the cross-flow fan blade 21. The second cleaning component 12 is disposed toward the evaporator 20 and the cross-flow fan blade 21 respectively to spray cleaning liquid onto the evaporator 20 and the cross-flow fan blade 21 respectively.

[0034] In one aspect of the technical solution of this invention, by separately configuring the first cleaning component 11 and the second cleaning component 12, multi-level cleaning of key air outlet components of the air conditioner indoor unit can be achieved sequentially, improving the operational stability of the air conditioner indoor unit's fan blades and evaporator 20, and significantly improving the air outlet quality. Furthermore, by using the first cleaning component 11 and the second cleaning component 12 in conjunction, the evaporator 20 and cross-flow fan blades 21 of the air conditioner can be automatically cleaned, reducing the need for manual maintenance and improving cleaning efficiency and thoroughness. This solves the problem of low cleaning efficiency due to the cumbersome process of cleaning the evaporator 20 component in the prior art. Simultaneously, the cleaning component 10 is rotatably disposed between the evaporator 20 and the cross-flow fan blades 21, meaning it can cover most of the surfaces of these components, including areas that are normally difficult to access, thus ensuring comprehensive 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 bracket 201 of the evaporator 20. A first cleaning component 11 and a second cleaning component 12 are respectively disposed on the cleaning pipe 13. The second cleaning component 12 includes multiple sets of nozzles 120 spaced apart along the circumferential direction of the cleaning pipe 13. Each set of nozzles 120 includes multiple nozzles 120 spaced apart along the extension direction of the cleaning pipe 13 for spraying cleaning fluid. This arrangement allows the cleaning pipe 13 to rotate during the cleaning process, driving the multiple sets of nozzles 120 to dynamically spray the evaporator 20 and the cross-flow fan blades 21 from different angles and orientations, achieving a more comprehensive cleaning effect, reducing cleaning dead zones, and minimizing the need for manual intervention. Furthermore, the distribution design of the nozzles 120 ensures uniform coverage of the cleaning fluid on the surfaces of the evaporator 20 and the cross-flow fan blades 21, avoiding problems of insufficient or excessive cleaning in certain areas, and improving cleaning efficiency and cleanliness.

[0036] Specifically, the first cleaning component 11 includes a plurality of extension members 110, which are spaced apart along the circumferential direction of the cleaning pipe 13. The plurality of extension members 110 are arranged in a one-to-one correspondence with a plurality of sets of nozzles 120. One side of the plurality of extension members 110 is rotatably connected to the cleaning pipe 13 via a rotating shaft 111 and covers the corresponding set 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] With the above configuration, during the cleaning process, as the rotation speed of the cleaning pipe 13 gradually increases, under the action of centrifugal force, multiple extension members 110 can rotate along the rotating shaft 111 to gradually open. When the multiple extension members 110 are opened to the preset position, the brushes 112 on the extension members 110 can effectively contact and clean the inner sides of the evaporator 20 and the cross-flow fan blades 21 respectively. Furthermore, at this time, multiple sets of nozzles 120 located under the multiple extension members 110 are exposed. Further, by supplying cleaning fluid into the cleaning pipe 13, the cleaning fluid can be sprayed 360° onto the evaporator 20 and the cross-flow fan blades 21 under the rotation of the cleaning components. Under the action of the brushes 112 on the multiple extension members 110, a deep cleaning of the air conditioner indoor unit is achieved, improving the comprehensiveness and efficiency of cleaning. Meanwhile, when the extension member 110 is closed, it covers the nozzle 120, which can prevent the cleaning fluid from being lost before reaching the cleaned surface and prevent dust from clogging the nozzle 120, ensuring the effective use of the cleaning fluid, reducing resource waste, and also avoiding the impact of the cleaning fluid on non-clean areas.

[0038] In this embodiment, each extension member 110 is an arc-shaped plate structure, and the inner wall surface of multiple extension members 110 respectively mates with the outer wall surface of the cleaning pipe 13. This allows the arc-shaped plate extension members 110 to flexibly adapt to the shape changes of the evaporator 20 and the cross-flow fan blades 21 when unfolded and rotated, achieving effective contact and cleaning regardless of whether the surface is flat or curved, thus enhancing the adaptability and flexibility of the cleaning assembly. It also helps guide the spray direction of the cleaning fluid, ensuring that the sprayed cleaning fluid acts more directly on the area requiring cleaning, improving the utilization rate of the cleaning fluid and the cleaning effect. Simultaneously, it can better adapt to the cleaning pipe 13 to suit the internal spatial layout of the air conditioner, making the overall structure of the cleaning assembly 10 more compact, saving valuable space inside the air conditioner and facilitating the arrangement of other components. Combined with the automatic rotation function of the cleaning assembly 10, the arc-shaped plate extension members 110 can perform all-round cleaning of the evaporator 20 and the cross-flow fan blades 21 without manual intervention, improving the automation level and maintenance efficiency of the air conditioner indoor unit.

[0039] like Figure 7As shown, the cleaning assembly 10 also includes multiple elastic elements 14, each corresponding to a multiple extension elements 110. One end of each elastic element 14 is connected to an extension element 110, and the other end is connected to the cleaning tube 13, allowing the extension element 110 to be movably positioned relative to the cleaning tube 13. This arrangement allows the extension element 110 to more flexibly adapt to the curved surfaces of the evaporator 20 and the cross-flow fan blades 21 when the cleaning tube 13 rotates. Even when encountering surface protrusions or depressions, the brush 112 can maintain good contact, thereby improving the comprehensiveness and efficiency of cleaning. Furthermore, after cleaning, the cleaning tube 13 gradually reduces its rotation speed, causing the extension element 110 to gradually close under the tension of the elastic elements 14 until it fits against the outer peripheral wall of the cleaning tube 13, returning to its initial state.

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

[0041] like Figure 5 As shown, the indoor unit of the air conditioner also includes a supply component 30, which is connected to the cleaning component 10 to provide cleaning fluid to the second cleaning component 12. This enables automatic delivery of cleaning fluid to the second cleaning component 12 without manual intervention, automating the cleaning process, simplifying maintenance procedures, and improving cleaning efficiency. It also ensures the pressure and flow rate of the cleaning fluid, allowing the nozzle 120 to effectively spray the cleaning fluid, 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 has mounting ears 310 for connecting to the angle bracket 201 of the evaporator 20. One end of the cleaning pipe 13 is rotatably connected to the connector 31. One end of the connecting pipe 32 communicates with the cleaning pipe 13 via the connector 31, and the other end of the connecting pipe 32 is connected to external equipment for supplying cleaning fluid into the cleaning pipe 13. This configuration, with the mounting ears 310 on the connector 31 connected to the angle bracket 201 of the evaporator 20, provides a secure positioning of the cleaning assembly 10, ensuring its stability and accuracy during cleaning and preventing reduced cleaning effectiveness due to positional deviation. The rotatable connection between the cleaning pipe 13 and the connector 31 allows the cleaning pipe 13 to rotate freely during cleaning, enhancing the flexibility of the cleaning assembly 10 and enabling comprehensive cleaning of the evaporator 20 and the cross-flow fan blades 21, thus improving the thoroughness and effectiveness of the cleaning process.

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

[0044] like Figure 4 As shown, the cleaning assembly 10 also includes a drive component 15, which is mounted on the angle bracket 201 of the evaporator 20. One end of the cleaning pipe 13 has a mounting recess 130. The output shaft of the drive component 15 extends into the mounting recess 130 to drive the cleaning pipe 13, thereby driving the cleaning pipe 13 to rotate. In this embodiment, the drive component 15 is a stepper motor. Thus, by precisely controlling the rotation speed and angle of the cleaning pipe 13 through the drive component 15, the cleaning process can be optimized, and the cleaning intensity and range can be adjusted according to different levels of contamination, improving cleaning efficiency and effectiveness. Furthermore, mounting the drive component 15 on the angle bracket 201 of the evaporator 20 utilizes the space of the angle bracket 201, avoiding additional space requirements and helping to optimize the internal structural layout of the air conditioner indoor unit, making it more compact.

[0045] In this embodiment, the indoor unit of the air conditioner also includes a detection unit disposed between the evaporator 20 and the cross-flow fan 21 to detect the contamination level of the evaporator 20 and the cross-flow fan 21 respectively. Through this configuration, the detection unit can monitor the contamination level of the evaporator 20 and the cross-flow fan 21 in real time. Based on a set contamination level threshold, it automatically determines when the cleaning assembly 10 needs to be activated for cleaning, achieving intelligent maintenance management, reducing the frequency of manual inspection and maintenance, and improving maintenance efficiency. Furthermore, based on the contamination level information provided by the detection unit, the air conditioner can precisely control the activation and cleaning intensity of the cleaning assembly 10, avoiding over-cleaning or under-cleaning, ensuring cleaning effectiveness while saving on cleaning fluid usage and reducing maintenance costs.

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

[0047] In another aspect of the technical solution of this invention, the indoor unit of the air conditioner integrates a cleaning component 10, which can automatically clean the evaporator 20 and the cross-flow fan blades 21. This not only improves cleaning efficiency and reduces maintenance cycles, but also ensures the cleanliness of the air conditioner's interior, extends the equipment's lifespan, and improves air quality and health. Furthermore, because the detection unit in the indoor unit can monitor the level of contamination and work in conjunction with the cleaning component 10, the air conditioner can achieve intelligent control, automatically adjusting the cleaning mode according to real-time changes in contamination levels without manual intervention, thus improving the user experience. Simultaneously, the automated and intelligent control of the cleaning component 10 can reduce unnecessary energy consumption, such as reducing the use of cleaning fluid when the contamination level is low, playing a positive role in energy conservation and environmental protection. At the same time, efficient cleaning reduces the increase in energy consumption caused by dust accumulation in the air conditioner, further improving the energy efficiency ratio.

[0048] According to another aspect of the present invention, an air conditioner control method is provided, applicable to the air conditioner mentioned above. The control method includes: setting a first pollution degree threshold and a second pollution degree threshold; obtaining the actual pollution degree of the evaporator 20 and the cross-flow fan blade 21 detected by the detection unit; comparing the actual pollution degree with the first pollution degree threshold and the second pollution degree 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 cross-flow fan blade 21 according to the comparison result; wherein the first pollution degree threshold is less than the second pollution degree threshold.

[0049] In another aspect of the technical solution of this invention, by setting two different contamination thresholds, the air conditioner can take different degrees of cleaning measures according to the actual contamination level. The first contamination threshold is used to trigger a lighter cleaning mode, such as only activating the first cleaning component 11 (physical cleaning), while the second contamination 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 fluid) to achieve deep cleaning. This reduces unnecessary energy consumption, thereby optimizing resource utilization and improving economic efficiency. At the same time, it reduces the need for manual maintenance by users, improving ease of use, as users do not need to worry about the timing and operation of air conditioner cleaning.

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

[0051] Specifically, when the actual contamination level is greater than or equal to the second contamination threshold, the first cleaning component 11 and the second cleaning component 12 are controlled to clean the evaporator 20 and the cross-flow fan blades 21, respectively. Thus, reaching the second contamination threshold typically indicates a significant accumulation of dust and dirt on the evaporator 20 and the cross-flow fan blades 21. At this point, simultaneously using the first cleaning component 11 and the second cleaning component 12 enables deep cleaning of the evaporator 20 and the cross-flow fan blades 21, thoroughly removing stubborn dirt and ensuring the cleanliness of the air conditioner's interior. Through intelligent control, the deep cleaning mode is activated only when necessary, reducing unnecessary energy consumption and cleaning fluid usage, meeting energy-saving and environmental protection requirements, and thereby improving the convenience of air conditioner use.

[0052] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0053] The indoor unit of the air conditioner includes an evaporator 20 and a cross-flow fan 21, and also includes a cleaning assembly 10. The cleaning assembly 10 is rotatably disposed between the evaporator 20 and the cross-flow fan 21. The cleaning assembly 10 includes a first cleaning component 11 and a second cleaning component 12. The first cleaning component 11 is movably in contact with both the evaporator 20 and the cross-flow fan 21 to clean dust from them. The second cleaning component 12 is positioned towards both the evaporator 20 and the cross-flow fan 21 to spray cleaning fluid onto them. Thus, by individually configuring the first cleaning component 11 and the second cleaning component 12, multi-level cleaning of the key air outlet components of the indoor unit can be achieved sequentially, improving the operational stability of the fan blades and evaporator 20, and significantly improving the air outlet quality. Furthermore, through the coordinated use of the first cleaning component 11 and the second cleaning component 12, the evaporator 20 and cross-flow fan blades 21 of the air conditioner can be automatically cleaned and purified, reducing the need for manual maintenance and improving cleaning efficiency and thoroughness. This solves the problem of low cleaning efficiency caused by the cumbersome process of cleaning the evaporator 20 component in the prior art. Simultaneously, the cleaning component 10 is rotatably disposed between the evaporator 20 and the cross-flow fan blades 21, meaning it can cover most of the surfaces of these components, including areas that are normally difficult to reach, thus ensuring comprehensive cleaning.
