Description

TECHNICAL FIELD

[0001] The present application relates to the air conditioning technical field, and more particularly, to a self-cleaning device, an air conditioner having the same, a cleaning method and an electronic device. BACKGROUND

[0002] The air conditioner produces condensate water during operation. The condensate water is collected through a waterway (water pan) and then discharged to the outside through a drain pipe.

[0003] With the extension of the use time, the water pan is in a humid and warm environment for a long time. In this environment, the bacteria and mold in the water pan multiply, which affects the indoor air quality. On the other hand, the existence of these microorganisms also secretes a kind of mucus, which is like an adhesive. This mucus will stick together with dust, particles and other substances to form sticky sediment and adhere to the surface of the water pan, thereby affecting the normal use of the air conditioner. This phenomenon is called biological slime in the industry.

[0004] In the prior art, the cleaning methods for the biological slime in the water pan of the air conditioner include contact type antibiosis and precipitation type antibiosis.

[0005] For the cleaning method of contact type antibiosis, the surface material of the water pan is subjected to antibacterial treatment. However, the effect of this antibacterial treatment is limited, especially when the surface of the water pan after antibacterial treatment is covered with pollutants, it cannot play its normal role.

[0006] For the cleaning method of precipitation type antibiosis, the main mechanism is to make the antibacterial substances precipitate and play a role through the condensate water remaining in the water pan. However, the speed of this cleaning method is not controllable, the effect is difficult to last, and it cannot play a normal role in the case of long-term use.

[0007] In summary, the existing technology mainly includes the above two methods to solve the biological slime, but both of the above two methods have certain defects, which leads to the fact that there is no way to effectively remove the biological slime in the water pan in the existing technology.

DETAILED DESCRIPTION

[0089] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0090] An air conditioner produces condensate water during operation. The produced condensate water is collected through a water channel (water pan) and then discharged to the outdoor through a drain pipe.

[0091] With the extension of the use time, the water pan is in a humid and warm environment for a long time. In this environment, the bacteria and molds in the water pan multiply, which affects the indoor air quality on one hand and the existence of these microorganisms also secretes a kind of mucus, which is like an adhesive. This mucus will stick together with dust, particles and other substances to form sticky sediment and adhere to the surface of the water pan, thereby affecting the normal use of the air conditioner. This phenomenon is called biological slime in the industry.

[0092] In the prior art, the cleaning method for the biological slime in the water pan of the air conditioner includes contact type antibiosis and precipitation type antibiosis.

[0093] For the contact type antibacterial cleaning method, the water receiving plate surface material is subjected to antibacterial treatment, but the effect of such antibacterial treatment is limited, especially when the water receiving plate surface after antibacterial treatment is covered by pollutants, the water receiving plate surface cannot play its normal role.

[0094] For the precipitation type antibacterial cleaning method, the main mechanism is to make the antibacterial substances precipitate and play a role through the residual condensed water in the water receiving plate, but the speed of such cleaning method is not controllable, the effect is difficult to last, and there is no way to play a normal role in a long time use.

[0095] In summary, the existing technology mainly includes the above two ways to solve biological slime, but the above two solutions have certain defects, which further leads to the fact that there is no way to effectively remove the biological slime in the water receiving plate in the existing technology.

[0096] Therefore, the purpose of the present application is to provide a self-cleaning device, an air conditioner having the same, a cleaning method and an electronic device for the above problems.

[0097] Firstly, the present application provides a self-cleaning device, comprising: a water receiving plate 1 for collecting condensed water, the water receiving plate 1 having a water inlet end and a water outlet end, along the direction from the water inlet end to the water outlet end, the water receiving plate 1 gradually inclines downward;

[0098] cleaning the heat exchanger 3, the cleaning heat exchanger 3 is arranged above the water inlet end of the water receiving plate 1;

[0099] an electrolysis module 2 installed on the water receiving plate 1 and located at the water inlet end, so as to obtain active bactericidal substances by electrolyzing the condensed water generated by the cleaning heat exchanger 3, so that the active bactericidal substances flow from the water inlet end to the water outlet end in the water receiving plate 1, so as to decompose the biological slime in the water receiving plate 1.

[0100] Specifically, as shown in Figures 1 to 7 The self-cleaning device provided by the present application includes a water receiving plate 1 for collecting condensed water, the water receiving plate 1 has a water inlet end and a water outlet end, along the direction from the water inlet end to the water outlet end, the water receiving plate 1 gradually inclines downward, so that the collected condensed water can flow from the water inlet end to the water outlet end, wherein the cleaning heat exchanger 3 is arranged above the water inlet end, and the electrolysis module 2 is arranged at the water inlet end, so that after the cleaning heat exchanger 3 generates the condensed water, the condensed water can directly fall into the water inlet end and be decomposed by the electrolysis module 2, and active bactericidal substances are obtained, so as to decompose the biological slime in the water receiving plate 1. The electrolysis module 2 is arranged at the water inlet end, so that the condensed water flowing out of the cleaning heat exchanger 3 can be electrolyzed in the first time, so that the active bactericidal substances obtained after electrolysis can decompose the biological slime in the water receiving plate 1.

[0101] In the technical scheme provided in the application, the self-cleaning device is provided with the cleaning heat exchanger 3 above the water inlet end of the water receiving tray 1 and the electrolysis module 2 at the water inlet end, so that the biological slime in the water channel of the air conditioner can be effectively decomposed and cleaned, and the efficiency of decomposing the biological slime is maximized.

[0102] Specifically, the cleaning heat exchanger 3 is arranged above the water inlet end of the water receiving tray 1, and its main task is to preferentially generate condensate water under certain conditions when the air conditioner is running. Since the position is close to the high position of the water receiving tray 1, the generated condensate water can quickly flow into the water receiving tray 1, and the electrolysis module 2 is located at the water inlet end, so that the flowing condensate water can be immediately subjected to electrolysis treatment to generate active bactericidal substances. These active bactericidal substances will then flow along the inclined surface of the water receiving tray 1 to the entire area of the water receiving tray 1, effectively decomposing the biological slime in the water channel, thereby achieving the effect of deep cleaning.

[0103] The arrangement of the electrolysis module 2 at the water inlet end can ensure that the condensate water is decomposed as soon as it enters the water receiving tray 1, thereby avoiding the loss of active bactericidal substances during the transmission process, improving the bactericidal efficiency, and at the same time, the active bactericidal substances flowing along the inclined surface of the water receiving tray 1 can cover a wider area, ensuring the overall cleaning of the water receiving tray 1 and avoiding the generation of cleaning dead angles.

[0104] Further, the cleaning heat exchanger 3 and the main heat exchanger 18 of the air conditioner indoor unit are arranged to be on-off, so that when the water receiving tray 1 needs to be cleaned, the flow of the condensate water into the cleaning heat exchanger 3 or the main heat exchanger 18 is controlled, so that the cleaning heat exchanger 3 generates condensate water.

[0105] Specifically, the cleaning heat exchanger 3 and the main heat exchanger 18 of the air conditioner indoor unit are arranged to be on-off, so that when the water receiving tray 1 needs to be cleaned, the flow of the condensate water into the cleaning heat exchanger 3 or the main heat exchanger 18 is controlled, so that the cleaning heat exchanger 3 generates condensate water.

[0106] The on-off design between the cleaning heat exchanger 3 and the main heat exchanger 18 of the air conditioner indoor unit in the application provides a flexible and efficient control mechanism for the self-cleaning of the water receiving tray 1, and targeted cleaning can be performed.

[0107] By controlling the refrigerant flow between the cleaning heat exchanger 3 and the main heat exchanger 18, it can be ensured that the cleaning heat exchanger 3 generates condensate water only when the water receiving tray 1 needs to be cleaned. This way avoids the waste of resources and ensures the perfect match between the generation of condensate water and the cleaning demand, thereby improving the cleaning efficiency and the utilization rate of condensate water.

[0108] The technical scheme of the present application can adjust the refrigerant flow entering the cleaning heat exchanger 3 according to the pollution degree of the water receiving tray 1, thereby avoiding unnecessary energy consumption; the cleanable connection between the cleaning heat exchanger 3 and the main heat exchanger 18 enables the cleaning work of the water receiving tray 1 to be performed independently, without relying on the overall operation of the air conditioner, which not only prolongs the service life of the cleaning heat exchanger 3, but also reduces the air conditioner maintenance and repair requirements caused by biological slime accumulation, thereby reducing the user's maintenance cost and operation complexity.

[0109] Further, the cleaning heat exchanger 3 comprises a first fin 6;

[0110] The first heat exchange pipeline 7 arranged in the first fin 6, the inlet end of the first heat exchange pipeline 7 is communicated with one end of the second heat exchange pipeline 5 in the main heat exchanger 18 which is relatively close to the refrigerant water inlet, and the outlet end of the first heat exchange pipeline 7 is communicated with one end of the second heat exchange pipeline 5 which is relatively close to the refrigerant water outlet through the second conversion component 9, so that when biological slime needs to be decomposed, the flow of refrigerant water in the second heat exchange pipeline 5 and the first heat exchange pipeline 7 is adjusted through the first conversion component 8 and the second conversion component 9, so that the cleaning heat exchanger 3 generates condensate water for electrolysis of the electrolysis module 2.

[0111] Specifically, the cleaning heat exchanger 3 comprises a first fin 6, a first heat exchange pipeline 7 arranged in the first fin 6, and a second heat exchange pipeline 5 arranged in the main heat exchanger 18, the inlet end of the first heat exchange pipeline 7 is communicated with one end of the second heat exchange pipeline 5 which is relatively close to the refrigerant water inlet, so as to deliver refrigerant water into the second heat exchange pipeline 5 through the refrigerant water inlet, and the outlet end of the first heat exchange pipeline 7 is communicated with one end of the second heat exchange pipeline 5 which is relatively close to the refrigerant water outlet through the second conversion component 9, when biological slime in the water receiving tray 1 needs to be decomposed, the flow of refrigerant water flowing into the first heat exchange pipeline 7 and the second heat exchange pipeline 5 and the flow of refrigerant water flowing out of the first heat exchange pipeline 7 and the second heat exchange pipeline 5 can be adjusted by controlling the opening degree of the first conversion component 8 and the second conversion component 9, and the flow of condensate water generated by the cleaning heat exchanger 3 can be indirectly controlled through this control mode, thereby the amount of active sterilization substances generated by the electrolysis module 2 when electrolyzing the condensate water can be controlled.

[0112] In the present application, the cleaning heat exchanger 3 and the main heat exchanger 18 are adjusted and controlled through the first conversion component 8 and the second conversion component 9, thereby realizing the distribution of the refrigerant water flow and the precise control of the generation amount of condensate water and active sterilization substances;

[0113] By adjusting the opening degree of the first conversion component 8 and the second conversion component 9, the amount of refrigerant water flowing into the first heat exchange pipeline 7 of the cleaning heat exchanger 3 and the second heat exchange pipeline 5 of the main heat exchanger 18 can be accurately controlled. The fine adjustment of the flow rate can ensure that the amount of condensed water generated matches the degree of pollution of the water pan 1, avoiding the problems of insufficient cleaning or excessive cleaning, and significantly improving the efficiency of the self-cleaning process.

[0114] The dynamic adjustment of the refrigerant water flow rate enables the cleaning heat exchanger 3 and the main heat exchanger 18 to effectively allocate refrigerant resources according to actual needs.

[0115] Further, the second heat exchange pipeline 5 includes a water inlet pipeline 501, an intermediate pipeline 502, and a water outlet pipeline 503; wherein:

[0116] The first conversion component 8 has a first inlet, two first outlets, the first inlet is in communication with the water outlet end of the water inlet pipeline 501, the two first outlets are respectively in communication with the inlet end of the intermediate pipeline 502 and the inlet end of the first heat exchange pipeline 7 of the first heat exchange pipeline 7; and / or,

[0117] The second conversion component 9 has a second inlet, two second outlets, the second inlet is in communication with the outlet end of the intermediate pipeline 502, the two second outlets are respectively in communication with the outlet end of the first heat exchange pipeline 7 and the inlet end of the water outlet pipeline 503.

[0118] Specifically, in the technical solution of the present application, the second heat exchange pipeline 5 is subdivided into a water inlet pipeline 501, an intermediate pipeline 502, and a water outlet pipeline 503, and the first conversion component 8 and the second conversion component 9 are designed with multiple ports to achieve fine control of the flow direction and flow rate of the refrigerant water, wherein the first conversion component 8 and the second conversion component 9 are both three-way valves.

[0119] Through the first conversion component 8 and the second conversion component 9, the refrigerant water flow rate into the first heat exchange pipeline 7 (part of the cleaning heat exchanger 3) and the second heat exchange pipeline 5 (part of the main heat exchanger 18) can be flexibly adjusted according to the degree of pollution of the water pan 1 and the cleaning demand. When the water pan 1 needs to be deeply cleaned, the refrigerant water flow rate flowing to the cleaning heat exchanger 3 can be increased to generate more condensed water for the electrolysis module 2 to process; on the contrary, when the cleaning demand is low, the flow rate can be reduced, thereby achieving efficient use of resources.

[0120] Through the dynamic adjustment of the first conversion component 8 and the second conversion component 9 to the refrigerant water flow rate, the stability of the air conditioning system operation can be maintained while ensuring the cleaning effect. This design avoids the impact of the cleaning process on the air conditioning refrigeration or heating function, ensures the comfort experience of users during the cleaning process, and also improves the overall operating efficiency of the system.

[0121] Further, the first heat exchange pipeline 7 includes:

[0122] a plurality of first sub-pipes 701 extending along a first direction and arranged along a second direction, the first direction being perpendicular to the second direction, the first direction being the arrangement direction of the cleaning heat exchanger 3 and the main heat exchanger 18;

[0123] a plurality of first connecting pipes 702, two ports of each of the plurality of first connecting pipes 702 being in communication with ports of two adjacent first sub-pipes 701.

[0124] Specifically, in the present application, the first heat exchange pipe 7 includes a plurality of first sub-pipes 701 and a plurality of first connecting pipes 702, the plurality of first sub-pipes 701 extending along a first direction perpendicular to the arrangement direction of the cleaning heat exchanger 3 and the main heat exchanger 18, thereby increasing the contact area of the refrigerant water and the air and improving the heat exchange efficiency, which means that the heat exchange effect can be achieved more quickly during the generation of the condensate water, the formation of the condensate water is accelerated, and the efficiency of the cleaning process is improved. The first connecting pipes 702 connect adjacent first sub-pipes 701, ensuring that the refrigerant water can be uniformly distributed in the entire first heat exchange pipe 7, avoiding local accumulation or uneven flow of the refrigerant water in the pipe, ensuring stable generation of the condensate water, and improving the overall performance of the cleaning heat exchanger 3.

[0125] Further, the intermediate pipe 502 includes: a plurality of second sub-pipes 5021 extending along a first direction and arranged along a second direction, the first direction being perpendicular to the second direction, the first direction being the arrangement direction of the cleaning heat exchanger 3 and the main heat exchanger 18;

[0126] a plurality of second connecting pipes 5022, two ports of each of the plurality of second connecting pipes 5022 being in communication with ports of two adjacent second sub-pipes 5021.

[0127] Specifically, in the present application, the intermediate pipe 502 comprises a plurality of second branch pipes 5021 extending in a first direction perpendicular to the arrangement direction of the cleaning heat exchanger 3 and the main heat exchanger 18, and a plurality of second connecting pipes 5022 connecting adjacent second branch pipes 5021, which can ensure more uniform distribution of the refrigerant water between the cleaning heat exchanger 3 and the main heat exchanger 18, thereby improving the uniformity and efficiency of heat exchange. This means that both the cleaning heat exchanger 3 and the main heat exchanger 18 can obtain sufficient refrigerant water to achieve efficient heat exchange, ensuring the performance of the air conditioner in cleaning and normal operation modes. The refrigerant water can flow smoothly throughout the intermediate pipe 502 through the second connecting pipes 5022, avoiding local retention and promoting rapid generation of condensate water. This design ensures that when cleaning is needed, the cleaning heat exchanger 3 can quickly reach the optimal condensate water production rate, improving the efficiency of the electrolysis module 2 in decomposing biological slime. The design of the second branch pipes 5021 and the second connecting pipes 5022, through the uniform distribution and smooth flow of refrigerant water, reduces pressure fluctuations and local overheating within the system, enhancing the stability and reliability of the system.

[0128] Further, the self-cleaning device further comprises:

[0129] a detection module installed in the water pan 1 to detect the real-time temperature of the first fin 6 and a first temperature difference between the real-time temperature and the dew point temperature;

[0130] a control module connected with the detection module and the electrolysis module 2 to control the operating parameters of the electrolysis module 2 according to the first temperature difference;

[0131] wherein the operating parameters include operating voltage and electrolysis time.

[0132] Specifically, the detection module is installed in the water pan 1 to monitor the temperature of the first fin 6 in real time. The first temperature difference between the temperature and the dew point temperature reflects the generation conditions of the condensate water. This real-time monitoring capability enables the system to dynamically adjust the cleaning strategy according to environmental changes, improving the accuracy and efficiency of cleaning. The control module is connected with the detection module and the electrolysis module 2, and can automatically adjust the operating parameters of the electrolysis module 2, such as operating voltage and electrolysis time, according to the first temperature difference, so that when the condensate water generation rate changes, the electrolysis module 2 can quickly adjust its operating state to maintain the stability of the active bactericidal substance generation amount, ensuring that the cleaning effect is not affected by environmental temperature fluctuations.

[0133] By dynamically adjusting the operating parameters of the electrolysis module 2, the condensed water can be more efficiently utilized. When the condensed water generation rate is low, the operating voltage is increased or the electrolysis time is prolonged to ensure sufficient generation of active sterilization substances; when the condensed water generation rate is high, the operating voltage can be appropriately reduced or the electrolysis time can be shortened to reduce energy consumption, thereby optimizing energy utilization.

[0134] Further, the self-cleaning device further comprises a condensed water channel 10 provided on the water pan 1, wherein the water inlet of the condensed water channel 10 is in communication with the collection port at the first fin 6 of the heat exchanger 3.

[0135] A drain port 11 is provided on the condensed water channel 10 to drain the condensed water on the condensed water channel 10 to the outside of the air conditioner indoor unit.

[0136] The electrolysis module 2 is provided at the water inlet of the condensed water channel 10.

[0137] Specifically, please refer to Figure 2 and Figure 3 The water pan further comprises a condensed water channel provided on the water pan 1, wherein the water inlet of the condensed water channel 10 is in communication with the collection port at the first fin 6, and a drain port 11 is further provided on the condensed water channel 10 to drain the condensed water on the condensed water channel 10 to the outside of the air conditioner indoor unit, and the electrolysis module 2 is provided at the water inlet of the condensed water channel 10.

[0138] In use, the condensed water generated on the first fin 6 of the air conditioner indoor unit flows into the water inlet of the condensed water channel 10 through the collection port, and then flows into the condensed water channel 10 through the water inlet, and is drained out through the drain port 11 of the condensed water channel. In the process of the condensed water entering the water inlet of the condensed water channel 10 through the collection port, the electrolysis module 2 electrolyzes the condensed water to generate active sterilization substances, which can react with the biological slime in the water pan 1. After the reaction, the product formed is discharged from the drain port 11 of the condensed water channel 10 and then discharged from the drain port 11.

[0139] Further, the condensed water channel 10 comprises a first condensed water flow channel 101 provided on the water pan 1, wherein the first condensed water flow channel 101 has a third inlet and a third outlet, and the distance between the first condensed water flow channel 101 and the bottom surface of the water pan 1 gradually decreases along the extension direction from the third inlet to the third outlet.

[0140] The second condensed water flow channel 102 is provided on the water pan 1, wherein the second condensed water flow channel 102 has a fourth inlet and a fourth outlet, and the distance between the second condensed water flow channel 102 and the bottom surface of the water pan 1 gradually decreases along the extension direction from the fourth inlet to the fourth outlet.

[0141] The third and fourth outlets are both connected to the drainage outlet 11, and the third and fourth inlets are both connected to the collection outlet.

[0142] Specifically, such as Figure 2 As shown, the condensate channel 10 includes a first condensate flow channel 101 disposed on the drip tray 1. The first condensate flow channel 101 has a third inlet and a third outlet. The distance between the first condensate flow channel 101 and the bottom surface of the drip tray 1 gradually decreases along the extension direction from the third inlet to the third outlet. That is, the first condensate flow channel 101 is inclined relative to a first plane, wherein the first plane is parallel to the ground and perpendicular to the plane of the wall (the wall where the air conditioner is installed). Figure 5 As shown, the first condensate flow channel 101 is inclined relative to the first plane. Figure 5 The included angle is the angle A formed between the first condensate flow channel 101 and the horizontal plane. The size of the included angle A can be set according to the actual situation. Figure 5 For the purpose of illustrating that the first condensate flow channel 101 is inclined relative to the first plane, similarly, the second condensate flow channel 102 is also inclined relative to the first plane. This arrangement allows the active bactericidal substance formed after electrolysis by the electrolysis module 2 at the inlet of the condensate flow channel 10 to flow automatically and clean the biological slime on the first condensate flow channel 101. The condensate flow channel also includes a second condensate flow channel 102, which is located on the water receiving tray 1. The second condensate flow channel 102 has a fourth inlet and a fourth outlet. The second condensate flow channel 102 extends from the fourth inlet to the first... The distance between the extension direction of the four outlets and the bottom surface of the water receiving tray 1 gradually decreases. The third and fourth outlets are connected to the drain outlet 11, and the third and fourth inlets are connected to the collection port. The condensate flowing out of the collection port enters the first condensate flow channel 101 and the second condensate flow channel 102 respectively, and flows into the corresponding third and fourth outlets respectively, and then flows out from the drain outlet 11. With the configuration of this application, the active bactericidal substances generated by the electrolysis module 2 in the electrolysis of condensate can automatically flow into the drain outlet 11 after reacting with the biological slime, and then be discharged from the drain outlet 11.

[0143] Furthermore, the condensate channel 10 includes:

[0144] The third condensate flow channel 12 is provided on the water receiving pan 1, and the third condensate flow channel 12 has a fifth inlet and a fifth outlet;

[0145] The minimum distance between the fifth inlet and the bottom surface of the water receiving tray 1 is the first distance, and the minimum distance between the fifth outlet and the bottom surface of the water receiving tray 1 is the second distance. The first distance is greater than the second distance.

[0146] Specifically, as shown in Figure 3 the condensed water channel further comprises a third condensed water flow channel 12 arranged on the water pan 1, as shown in Figure 3 the third condensed water flow channel 12 has a fifth inlet and a fifth outlet, wherein the fifth inlet is in communication with the collection port, and the fifth outlet is in communication with the drain port 11;

[0147] The third condensed water flow channel 12 comprises a first flow channel, a second flow channel and a third flow channel connected in sequence. The first flow channel, the second flow channel and the third flow channel are all arranged inclined along the flow direction of the condensed water, that is, the height between the third condensed water flow channel 12 and the bottom surface of the water pan 1 gradually decreases along the flow direction of the condensed water (the first flow channel, the second flow channel and the third flow channel are all arranged inclined relative to the first plane, the vertical distance between the outlet end of the first flow channel and the first plane is greater than the vertical distance between the outlet end of the second flow channel and the first plane, which is greater than the vertical distance between the outlet end of the third flow channel and the first plane), facilitating the flow of condensed water. In use, the condensation on the first fin 6 enters the fifth inlet from the collection port, and then enters the first flow channel from the fifth inlet, and then flows through the second flow channel and the third flow channel in sequence, and then enters the fifth outlet, and then flows out from the drain port 11. The distance between the fifth inlet and the bottom surface of the water pan 1 is a first distance, and the distance between the third outlet and the bottom surface of the water pan 1 is a second distance, and the first distance is greater than the second distance, which can ensure that the condensed water in the third condensed water flow channel 12 can flow from the fifth inlet to the fifth outlet, so that the active sterilization substance generated by electrolysis of the electrolysis module 2 can also decompose the biological slime in the water pan 1 during the flow, and the product after decomposition can flow into the fifth outlet along the third condensed water flow channel 12 and then flow out from the drain port 11.

[0148] Further, the detection module comprises: a pollutant sensor for detecting the concentration of pollutants in the air entering the water pan 1 from the air inlet of the air conditioner indoor unit shell; and / or,

[0149] a temperature and humidity sensor for detecting the temperature and humidity of the air entering the water pan 1 from the air inlet of the air conditioner indoor unit shell.

[0150] Specifically, as shown in Figure 4 the detection module comprises a pollutant sensor and a temperature and humidity sensor arranged at the air inlet of the air conditioner indoor unit shell. The pollutant sensor can detect the concentration of pollutants in the air entering the water pan from the air inlet in real time, and the temperature and humidity sensor can detect the temperature and humidity of the air entering the water pan from the air inlet in real time.

[0151] The pollutant sensor detects the concentration of pollutants in the air entering the water tray 1 in real time, and the temperature and humidity sensor detects the temperature and humidity in the air. This allows the system to determine the degree of pollution in the water tray 1 based on real-time changes in the indoor environment. It can also monitor the concentration of pollutants and the temperature and humidity of the indoor air in real time, ensuring that the electrolysis module 2 is activated in time to clean when the air conditions are poor, reducing the accumulation of biological slime, reducing the growth of bacteria and mold, and providing users with a healthier and cleaner indoor environment.

[0152] This application also provides an air conditioner, including an indoor unit and a self-cleaning device as described in any of the above claims, wherein the self-cleaning device is disposed inside the indoor unit.

[0153] Specifically, this application also provides an air conditioner, including an indoor unit and a self-cleaning device disposed in the indoor unit.

[0154] Furthermore, the indoor unit of the air conditioner includes a shell body 13, an air inlet is provided on the shell body 13, and a main air guide plate 19 and a cleaning air guide plate 20 are rotatably provided on the air inlet and arranged in a predetermined direction. The cleaning heat exchanger 3 is disposed inside the shell body 13 and is correspondingly arranged with the cleaning air guide plate 20. The main heat exchanger 18 is disposed inside the shell body 13 and is correspondingly arranged with the main air guide plate 19.

[0155] Specifically, such as Figure 6 As shown, the indoor unit of the air conditioner includes a housing 13, on which an air inlet is provided. A main air guide vane 19 and a cleaning air guide vane 20 are rotatably disposed at the air inlet. The main air guide vane 19 and the cleaning air guide vane 20 are arranged along... Figure 6 The air conditioner is arranged along its length. The cleaning heat exchanger 3 is located inside the shell body 13 and is positioned corresponding to the cleaning air guide plate 20. The main heat exchanger 18 is located inside the shell body 13 and is positioned corresponding to the main air guide plate 19.

[0156] This application embodiment also provides a method for cleaning an air conditioner, applicable to the aforementioned air conditioner, and the method for cleaning the air conditioner includes:

[0157] S1. Obtain the degree of contamination of the air conditioner's drip tray 1 to determine whether the air conditioner's drip tray 1 needs to be cleaned.

[0158] S2. When it is determined that the water tray 1 needs to be cleaned, the main air deflector 19 of the air conditioner is closed, the cleaning air deflector 20 of the air conditioner is opened, and the air outlet deflector 15 at the air outlet of the air conditioner is opened. The opening degree of the first conversion component 8 and the second conversion component 9 in the self-cleaning device is controlled so that the refrigerant flows from the refrigerant water inlet into the first heat exchange pipe 7 of the cleaning heat exchanger 3 of the air conditioner, so that the cleaning heat exchanger 3 produces condensate water, and the condensate water is electrolyzed by the electrolysis module 2 to produce active bactericidal substances to decompose the biological slime in the water tray 1.

[0159] Specifically, as shown in Figure 8 The application further provides a cleaning method of the air conditioner, which is suitable for the air conditioner described above, and the cleaning method of the air conditioner comprises the following steps of:

[0160] After determining that the air conditioner is powered on and running, in response to a cleaning instruction issued by a user, the pollution degree of the water receiving tray 1 inside the air conditioner is obtained after receiving the cleaning instruction, and it is determined whether the water receiving tray 1 in the air conditioner needs to be cleaned according to the pollution degree. When it is determined that the water receiving tray 1 does not need to be cleaned, first display information is generated and sent to the electronic device, so that the electronic device can present the first display information, wherein the first display information is used to prompt the user that the water receiving tray 1 is currently clean and does not need to be cleaned by the user, so as to avoid the user's doubt about whether the function of the air conditioner is normally running.

[0161] Further, after the step of determining to clean the water receiving tray 1, the following steps are included:

[0162] The fan 16 of the air conditioner is controlled to run at a first wind speed, and the compressor is controlled to run at a first frequency under a first preset condition for a first preset time length, so that condensation is generated on the first fins 6 of the heat exchanger 3, and condensate water is obtained and flows into the water receiving tray 1.

[0163] The first preset condition is that the temperature of the first fins 6 is less than a first temperature, and the first temperature is the dew point temperature corresponding to the indoor air.

[0164] Specifically, after the step of determining that the water receiving tray 1 needs to be cleaned, the current wind speed of the fan 16 of the air conditioner is adjusted to the first wind speed, the current frequency of the compressor is set to the first frequency, and the first preset condition is run for the first preset time length, so that condensation is generated on the first fins 6 of the heat exchanger 3, and condensate water is obtained and flows into the water receiving tray 1. The first preset condition is that the temperature of the first fins 6 is less than a first temperature, and the first temperature is the dew point temperature corresponding to the indoor air.

[0165] In the present application, after determining that the water receiving tray 1 needs to be cleaned, the wind speed of the fan 16 is adjusted to the first wind speed, the frequency of the compressor is set to the first frequency, and the first preset condition (i.e. the temperature of the first fins 6 is lower than the dew point temperature of the indoor air) is run. This series of operations can ensure that condensate water is generated on the cleaning heat exchanger 3 efficiently.

[0166] By setting the first wind speed and the first frequency, the air conditioner can run with lower energy consumption while meeting the cleaning demand. Compared with continuous high-intensity operation, this strategy can effectively reduce energy waste and reduce operating costs.

[0167] Since the first preset condition is set as the temperature of the first fin 6 being lower than the dew point, this condition can ensure that the condensed water is preferentially generated on the cleaning heat exchanger 3, thereby more effectively utilizing the electrolysis module 2 for cleaning. This method of directional generation of condensed water improves the cleaning efficiency and effect, and ensures the cleanliness and hygiene of the water pan 1.

[0168] Further, the step of obtaining the pollution degree of the water pan 1 of the air conditioner comprises:

[0169] obtaining the historical cleaning duration of the air conditioner, the historical cleaning duration being the cumulative running duration when the water pan 1 of the air conditioner is last cleaned;

[0170] detecting the indoor air quality to obtain the average concentration of pollutants in the indoor air within the historical cleaning duration, the pollutants at least including one or more of formaldehyde, ammonia, VOC, and PM2.5;

[0171] determining the pollution degree according to the historical cleaning duration and the average concentration;

[0172] Further, the step of determining the pollution degree according to the historical cleaning duration and the average concentration comprises:

[0173] when the historical cleaning duration is greater than or equal to a first preset threshold value, and the average concentration is greater than or equal to a first concentration threshold value, it is determined that the pollution degree of the water pan 1 has reached a degree that requires cleaning of the water pan 1.

[0174] Specifically, the historical cleaning duration of the air conditioner is obtained, and it is determined whether the air conditioner needs to be self-cleaned according to the historical cleaning duration, wherein the historical cleaning duration is the cumulative running duration when the water pan 1 of the air conditioner is last self-cleaned, and the historical cleaning duration can be determined by the running duration of the motor of the air conditioner. At the same time, the average concentration of pollutants in the indoor air within the historical cleaning duration is also calculated, and the pollution degree of the water pan 1 is determined according to the historical cleaning duration and the average concentration. When the historical cleaning duration is less than a first preset threshold value, and the average concentration is greater than a first concentration threshold value, it is indicated that the air conditioner has been running for a long time, and the pollution degree of the water pan has reached a degree that requires cleaning. Therefore, the water pan needs to be cleaned, and if cleaning is not performed in time, it will affect the health use of the user.

[0175] Further, the step of decomposing the biological slime in the water pan 1 comprises:

[0176] the cumulative running duration of the electrolysis module 2 is recorded, and when the cumulative running duration reaches a first preset duration, the electrolysis module 2 is turned off to allow the water pan 1 to stand still;

[0177] after the water pan 1 stands still for the first preset duration, the drain opening 11 of the water pan 1 is controlled to be opened to drain the condensed water in the water pan 1.

[0178] The cleaning air deflector 20, the main air deflector 19 and the air outlet air deflector 15 are controlled to be opened, the opening degree of the first conversion component 8 and the second conversion component 9 is controlled, so that the refrigerant flows into the second heat exchange pipeline 5 of the main heat exchanger 18 of the air conditioner from the refrigerant water inlet, the fan 16 is controlled to operate at the second wind speed, the compressor is controlled to operate at the second frequency, and the air conditioner operates under the second preset condition, and the operation time of the fan 16 and the compressor is accumulated to reach the second operation time length, so as to dry the condensed water in the water receiving tray 1 in the air conditioner.

[0179] The second preset condition is that the temperature of the second fin 4 of the air conditioner is greater than the second temperature.

[0180] Specifically, the accumulated operation time length of the electrolysis module 2 from starting to the present is recorded. Once the time length reaches the preset first preset time length, the system automatically closes the electrolysis module 2 and stops the generation of the active sterilization substance. The setting of the time length is based on experimental data to ensure that the biological slime is fully decomposed, while avoiding resource waste caused by excessive electrolysis. After the electrolysis module 2 is closed, the water receiving tray 1 enters a resting state and no longer performs any heat exchange or electrolysis operation, so as to give the active sterilization substance sufficient time to fully react with the biological slime. The first preset time length of the resting state is also determined based on experiments to ensure that the decomposition reaction is completed. After the resting state ends, the drain outlet 11 of the water receiving tray 1 is controlled to be opened, and the residual condensed water in the water receiving tray 1 is drained. The control during the drainage process ensures that the condensed water is completely removed, avoiding recontamination caused by residual moisture.

[0181] The cleaning air deflector 20, the main air deflector 19 and the air outlet air deflector 15 are controlled to be opened, the opening degree of the first conversion component 8 and the second conversion component 9 is controlled, so that the refrigerant flows into the second heat exchange pipeline 5 of the main heat exchanger 18, and efficient heat exchange is realized.

[0182] The fan 16 is controlled to operate at the second wind speed, and the compressor is controlled to operate at the second frequency. The second preset condition is set as the temperature of the second fin 4 of the air conditioner being greater than the second temperature. The setting of the condition ensures that the main heat exchanger 18 can generate sufficient heat for drying the water receiving tray 1.

[0183] The fan 16 and the compressor continue to operate until the accumulated operation time reaches the second preset time length. The time length is determined according to the size of the water receiving tray 1, the accumulated amount of biological slime and environmental temperature and humidity, etc., to ensure that the water receiving tray 1 is completely dried, avoiding the overgrowth of microorganisms caused by excessive humidity.

[0184] Through the accumulated operation time length control of the electrolysis module 2 and the resting process of the water receiving tray 1, the complete decomposition of the biological slime is ensured, and the thoroughness of cleaning is improved.

[0185] The combination of the standing and drying processes not only decomposes the biological slime, but also completely removes the residual moisture, avoids secondary pollution, and enhances the hygiene of the air conditioner.

[0186] In the electrolysis process, unnecessary resource consumption is avoided by precisely controlling the running time of the electrolysis module 2, and in the drying process, the distribution of the refrigerant water is optimized by adjusting the opening of the first conversion component 8 and the second conversion component 9, the heat exchange efficiency is improved, and the energy consumption is reduced.

[0187] Further, the method further comprises: when the historical cleaning duration is greater than the second preset threshold and less than the first preset threshold, and the average concentration is greater than the second concentration threshold and less than the first concentration threshold;

[0188] The cleaning guide vane 20 is controlled to be opened, the main guide vane 19 is controlled to be opened, the air outlet guide vane 15 is controlled to be opened, both first outlets of the first conversion component 8 are controlled to be at the first opening, so that the water inlet pipe 501 of the second heat exchange pipe 5 is in communication with the second heat exchange pipe 5 and the first heat exchange pipe 7 respectively, both second outlets of the second conversion component 9 are controlled to be at the second opening, so that the first heat exchange pipe 7 and the second heat exchange pipe 5 are in communication with the water outlet pipe 503 of the second heat exchange pipe 5 respectively, and the fan 16 is controlled to operate at the third wind speed, the compressor is controlled to operate at the third frequency, and the air conditioner operates under the third preset condition for a third preset duration, so that the second fin 4 and the first fin 6 generate condensation, and the condensed water is collected in the water pan 1.

[0189] The third preset condition is that the temperature of the first fin 6 is less than the first temperature, and the temperature of the second fin 4 is greater than the first temperature.

[0190] Specifically, when it is judged that the cleaning demand of the water pan 1 is in a medium state, i.e., the historical cleaning duration is greater than the second preset threshold and less than the first preset threshold, and the average concentration is greater than the second concentration threshold and less than the first concentration threshold, first, the cleaning guide vane 20, the main guide vane 19 and the air outlet guide vane 15 are controlled to be opened, so as to ensure that the air inside the air conditioner can circulate, and to create conditions for the generation of condensed water and drying.

[0191] Both first outlets of the first conversion component 8 are controlled to be at the first opening, so that the water inlet pipe 501 is in communication with the second heat exchange pipe 5 and the first heat exchange pipe 7 respectively, thereby realizing the distribution of the refrigerant water between the main heat exchanger 18 and the cleaning heat exchanger 3. This distribution mode in combination with the adjustment of the three-way valve can control the refrigerant water to flow through the cleaning heat exchanger 3 more, promote the generation of condensation on the second fin 4 and the first fin 6, and at the same time ensure that the refrigeration or heating function of the air conditioner is not significantly affected.

[0192] The two second outlets of the second switching component 9 are controlled to be at the second opening degree, so as to ensure that the first heat exchange pipeline 7 and the second heat exchange pipeline 5 are respectively communicated with the water outlet pipeline 503 of the second heat exchange pipeline 5, and the flow direction of the refrigerant water is further controlled, so as to ensure that the condensed water can be effectively utilized.

[0193] The fan 16 is controlled to operate at the third wind speed, the compressor is controlled to operate at the third frequency, and the third preset condition is that the temperature of the first fin 6 is less than the first temperature and the temperature of the second fin 4 is greater than the first temperature. The setting of the operation parameters, in combination with the heat exchange effect of the cleaning heat exchanger 3 and the main heat exchanger 18, can promote the generation of condensed water of the cleaning heat exchanger 3 while meeting the basic function of the air conditioner, thereby realizing the self-cleaning of the water pan 1.

[0194] By adjusting the opening degrees of the first switching component 8 and the second switching component 9, the refrigerant water resources are reasonably distributed, so that the condensed water meets the cleaning demand while not affecting the basic function of the air conditioner, and the resource utilization efficiency is improved.

[0195] Under the third preset condition of the air conditioner, the comfort of the indoor environment is ensured, and the generation of condensed water of the cleaning heat exchanger 3 is promoted, so that the cleaning and the basic function of the air conditioner are realized at the same time, and the overall performance of the equipment is improved.

[0196] The embodiment automatically adjusts the cleaning strategy according to the historical cleaning time length and the average concentration, can flexibly adjust the cleaning frequency and intensity under different use conditions, and adapts to different user and environmental requirements.

[0197] Further, after the step of obtaining the internal condensed water flowing to the water pan 1, the following steps are included:

[0198] The cumulative operation time length of the electrolysis module 2 is recorded, and when the cumulative operation time length reaches a third preset time length, the electrolysis module 2 is turned off, so that the water pan 1 is at rest;

[0199] After the water pan 1 is at rest for a third preset time length, the drain port 11 of the water pan 1 is controlled to be opened to drain the condensed water in the water pan 1;

[0200] The cleaning air deflector 20 is controlled to be opened, the main air deflector 19 is controlled to be opened, and the air outlet air deflector 15 is controlled to be opened, the opening degrees of the first switching component 8 and the second switching component 9 are controlled, so that the refrigerant flows into the second heat exchange pipeline 5 of the main heat exchanger 18 of the air conditioner from the refrigerant water inlet, the fan 16 is controlled to operate at the second wind speed, the compressor is controlled to operate at the second frequency, and the air conditioner is controlled to operate under the second preset condition, and the cumulative operation time of the fan 16 and the compressor reaches a second operation time length, so as to dry the condensed water of the water pan 1 in the air conditioner.

[0201] The second preset condition is that the temperature of the second fin 4 of the air conditioner is greater than a second temperature.

[0202] Specifically, the cumulative running time of the electrolysis module 2 is recorded while the water receiving tray 1 starts to receive the condensed water. When the cumulative running time reaches a third preset time length, the system automatically turns off the electrolysis module 2 and stops the electrolysis process. The setting of this time length is based on the comprehensive consideration of the processing effect of the electrolysis module 2 on the condensed water and the time required for the decomposition of the biological slime in the water receiving tray 1, ensuring the sufficiency and effectiveness of the cleaning process.

[0203] After the electrolysis module 2 is turned off, the water receiving tray 1 enters a resting state, and the resting time is set as the third preset time length. The purpose of the resting process is to allow the active sterilization substance to have sufficient time to react with the biological slime in the water receiving tray 1, ensuring that the biological slime is thoroughly decomposed and improving the cleaning effect.

[0204] After the resting process is completed, the drain port 11 of the water receiving tray 1 is controlled to open, and the condensed water in the water receiving tray 1 is drained. The draining process ensures that there is no water left in the water receiving tray 1, avoiding the growth of subsequent microorganisms and maintaining the dry state of the water receiving tray 1.

[0205] After the draining is completed, the cleaning air deflector 20, the main air deflector 19, and the air outlet air deflector 15 are controlled to open, ensuring the air circulation inside the air conditioner. The opening degree of the first conversion component 8 and the second conversion component 9 is controlled to adjust the flow direction of the refrigerant, so that the refrigerant flows from the refrigerant water inlet into the second heat pipe 5 of the main heat exchanger 18 of the air conditioner.
