Description

[0001] This application claims priority to Chinese Patent Application No. 202310234019.1, filed on March 10, 2023, entitled “Air Conditioner, Filtration Device, Ionization Device, Method and Device for Self-cleaning of Air Conditioner, and Storage Medium,” which is hereby incorporated by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of equipment cleaning, for example, to a control method and device for self-cleaning of an air conditioner, an air conditioner, and a computer-readable storage medium. BACKGROUND

[0003] Currently, for equipment with a temperature regulating device, such as an air conditioner with a heat exchanger, self-cleaning of the temperature regulating device is a problem that users are concerned about. For the heat exchanger, due to the variety of pollutants in the air, dirt is formed by long-term adhesion on the surface of the heat exchanger. If not cleaned in time, the heat exchange performance of the heat exchanger will decrease significantly, and even the air conditioner will frequently enter a protection state due to insufficient heat exchange performance, and cannot work normally. Therefore, the related technology provides an air conditioner that realizes self-cleaning of the heat exchanger by combining control and detection of refrigeration system parameters, including the following steps: obtaining a self-cleaning control instruction and entering a self-cleaning mode; adjusting the fan speed of the air conditioner and / or reducing the temperature of the indoor heat exchanger to make frost on the heat exchanger; and defrosting the heat exchanger after the frost is completed.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

[0005] In the process of self-cleaning of the heat exchanger, the condensation rate and the frost efficiency on the surface of the heat exchanger are slow, which further leads to insufficient frost amount, and finally leads to poor self-cleaning effect.

[0006] It should be noted that the information disclosed in the above BACKGROUND section is only used to strengthen the understanding of the background of the present application, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art. SUMMARY

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an overall description of the application, nor is it intended to determine key / important elements or delineate the scope of these embodiments, but as a prelude to the detailed description below.

[0008] The embodiments of the present disclosure provide a control method and device for self-cleaning of an air conditioner, an air conditioner, and a computer-readable storage medium, which can increase the frost amount on the surface of the heat exchanger, and is beneficial to improving the self-cleaning effect of the air conditioner.

[0009] In some embodiments, the air conditioner includes a housing; a heat exchanger disposed within the housing; and a water separation device disposed within the housing for separating water from the air onto the surface of the heat exchanger. The method includes: controlling the air conditioner to operate in a self-cleaning mode and activating the water separation device; and controlling the water separation device to close according to the fin gap of the heat exchanger when the air conditioner is operating in self-cleaning mode.

[0010] In some embodiments, the apparatus includes a processor and a memory storing program instructions, the processor being configured to execute the above-described control method for self-cleaning of an air conditioner when the program instructions are executed.

[0011] In some embodiments, the air conditioner includes: a housing; a heat exchanger disposed within the housing; a water separation device disposed within the housing for separating water from the air onto the surface of the heat exchanger; and the aforementioned control device for self-cleaning of the air conditioner disposed within the housing and electrically connected to the water separation device.

[0012] In some embodiments, the computer-readable storage medium stores program instructions that, when executed, cause the computer to perform the aforementioned control method for self-cleaning of an air conditioner.

[0013] The control method, apparatus, air conditioner, and computer-readable storage medium for self-cleaning of air conditioners provided in this disclosure can achieve the following technical effects:

[0014] In this embodiment, when the air conditioner is operating in self-cleaning mode, the operation of the water separation device can compensate for the self-cleaning mode, thereby improving the condensation and frosting efficiency of the heat exchanger. Simultaneously, by analyzing the fin gap of the heat exchanger, it can be determined whether the condensation or frosting amount meets the standard, and the water separation device can be controlled to shut down promptly when the standard is met, thus balancing the energy-saving effect of the water separation device. Under the action of the water separation device, more water molecules are adsorbed onto the surface of the heat exchanger, thereby increasing the amount of frosting on the heat exchanger surface, which is beneficial to improving the self-cleaning effect of the air conditioner.

[0048] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0049] Combination Figures 1-19 As shown, this embodiment of the present disclosure provides a device including a housing 100, a temperature regulating device 110, and a water separating device 200. The temperature regulating device 110 is disposed within the housing 100 and is used to regulate the temperature of the air. The water separating device 200 is disposed within the housing 100 and is used to separate water from the air onto the surface of the temperature regulating device 110; wherein the separated water is used to clean the temperature regulating device 110.

[0050] In this embodiment, the water separation device 200 is used to separate water from the air onto the surface of the temperature regulating device 110, causing rapid condensation on the surface of the temperature regulating device 110. This effectively improves the condensation efficiency of the temperature regulating device 110, which is beneficial for ensuring the cleaning effect of the temperature regulating device 110 in self-cleaning mode.

[0051] Optionally, the equipment includes an air conditioner, and the temperature regulating device 110 includes a heat exchanger.

[0052] In this embodiment, as Figure 1As shown, the air conditioner casing 100 is provided with an air inlet 101 and an air outlet 102. Air enters the casing 100 through the air inlet 101 and exchanges heat with the heat exchanger. The heat-exchanged air is then blown out through the air outlet 102, thereby regulating the air temperature. Furthermore, under the action of the water separation device 200, condensation can be quickly formed on the surface of the heat exchanger, and the condensed dew is then used to clean the heat exchanger.

[0053] Optionally, the water separation device 200 includes an ionization device, which comprises multiple discharge electrodes 210. The multiple discharge electrodes 210 are used to ionize air and generate ions. Water molecules and dust in the air combine with these ions and can be adsorbed onto the surface of the temperature regulating device 110. Thus, under the action of the discharge electrodes 210, when air flows through the water separation device 200, water molecules and dust in the air become charged ions.

[0054] Optionally, the discharge electrode 210 is connected to electricity and the temperature regulating device 110 is grounded, or the discharge electrode 210 and the temperature regulating device 110 are connected to electricity of opposite polarities, thereby ionizing the air; and, in the case of ionizing the air, the temperature of the temperature regulating device 110 is reduced so that water or frost for cleaning is condensed on its surface.

[0055] In this embodiment, as Figure 2 As shown, when the discharge electrode 210 is energized and the temperature control device 110 is grounded, a unipolar electric field is formed between the two. Figure 3 As shown, when the discharge electrode 210 and the temperature regulating device 110 are connected to electrodes of opposite polarity, an electric field of opposite charges is formed between them. When air flows through the single-stage electric field or the electric field of opposite charges, water molecules and dust in the air combine with ions generated by the discharge electrode 210, and the water molecules and dust become charged ions. Furthermore, the charged ions move towards the temperature regulating device 110 under the influence of the electric field force. Charged water molecules adsorbed onto the surface of the temperature regulating device 110 quickly condense, thus effectively improving condensation and dehumidification efficiency. Charged dust adsorbed onto the surface of the temperature regulating device 110 dissolves into the dew, and the accumulation of dust also increases frost formation. Additionally, the original dirt on the surface of the temperature regulating device 110 also dissolves into the dew. Then, as the temperature of the temperature regulating device 110 decreases, the water on the surface of the temperature regulating device 110 condenses into frost. At the same time, charged water molecules are also adsorbed onto the surface of the temperature regulating device 110, causing the frost layer to grow rapidly and continuously increase its density, thus also improving frost formation efficiency. This makes it easier to clean the surface of the temperature regulating device 110 with water or frost, while also cleaning dust in the air, and the charged ions can also have a bactericidal effect.

[0056] In this embodiment, when the temperature regulating device 110 is powered on, water molecules condense on the surface of the temperature regulating device 110 to form a water film, which is then polarized by the electric field. This creates a stronger electric field around the water film, attracting more water molecules and further improving the condensation efficiency.

[0057] The air conditioner features a self-cleaning mode, which includes a frosting stage and a defrosting stage, and can also include a condensation stage before the frosting stage. In this self-cleaning mode, a unipolar electric field or an opposite-charge electric field is formed between the discharge electrode 210 and the temperature control device 110. First, in the condensation stage, the air conditioner operates in cooling mode and the fan runs, causing air to be blown towards the temperature control device 110 via the water separator 200. When the air passes through the electric field, water molecules and dust in the air become charged ions, and the charged water molecules are adsorbed onto the surface of the temperature control device 110 and quickly condense. At this time, the dirt on the surface of the temperature control device 110 and the adsorbed charged dust dissolve into the dew. Next, in the frosting stage, the air conditioner operates in cooling mode and the fan stops. At this time, the dew on the surface of the temperature control device 110 condenses into frost. Surrounding water molecules can combine with the frost on the surface of the temperature control device 110, which facilitates rapid frost formation and increases the amount of frost. Finally, during the defrosting stage, the air conditioner operates in heating mode. At this time, the frost layer melts, and the dirt and dust are carried away from the surface of the temperature regulating device 110 by the melted water. In this way, the self-cleaning of the temperature regulating device 110 is completed, and the frosting efficiency can be improved by about 40% with the help of the water separation device 200.

[0058] The air conditioner also features a dehumidification mode, in which a unipolar electric field or an opposite-charge electric field is formed between the discharge electrode 210 and the temperature regulating device 110. During dehumidification, the air conditioner operates in cooling mode and the fan runs, causing air to be blown towards the temperature regulating device 110 via the water separation device 200. When the air passes through the electric field, water molecules in the air become charged ions, and these charged water molecules are adsorbed onto the surface of the temperature regulating device 110 and quickly condense. Thus, the dehumidification efficiency can be increased by 20%-30% under the action of the water separation device 200.

[0059] In the following embodiments, the electric field formed between the discharge electrode and the temperature regulation device, the movement of charged ions in the corresponding electric field, and the principle of the self-cleaning mode are all the same, and will not be repeated below.

[0060] Optionally, the ionization device further includes an ion generating device 212. The discharge electrode 210 is connected to a power source via the ion generating device 212; and, when the discharge electrode 210 is connected to the positive terminal of the power source, it generates positive ions, and when the discharge electrode 210 is connected to the negative terminal of the power source, it generates negative ions.

[0061] Optionally, the ionization device also includes an electrode control module. The electrode control module acts as a power source to supply power to some or all of the discharge electrodes 210, and the power supply is greater than or equal to 1W.

[0062] Optionally, the ionization device also includes an electrode control module. The electrode control module acts as a power source to supply power to some or all of the discharge electrodes 210, and the supply voltage is greater than or equal to 3 kV.

[0063] Optionally, the supply voltage is determined based on the distance d1 between adjacent discharge electrodes 210. The larger the distance d1 between adjacent discharge electrodes 210, the larger the supply voltage.

[0064] Optionally, the spacing d1 between adjacent discharge electrodes 210 is greater than or equal to 2 mm. Preferably, the spacing between adjacent discharge electrodes 210 is 2 mm to 100 mm.

[0065] Optionally, such as Figure 3 and Figure 5 As shown, the water separation device 200 also includes a mounting frame 230, on which a plurality of discharge electrodes 210 are disposed.

[0067] Optionally, the first frame 231 has a wire groove, and the transmission wire of the ion generator 212 is arranged in the wire groove. Furthermore, each discharge electrode 210 is connected to the transmission wire in the corresponding wire groove, so that the ion generator 212 can release negative or positive ions through the discharge electrode 210.

[0068] Optionally, the mounting frame 230 further includes a second frame 232 disposed along a second direction perpendicular to the first direction. Multiple first frames 231 and multiple second frames 232 are arranged in a grid pattern. A discharge electrode 210 is disposed at each intersection; wherein, as... Figure 4 As shown, the junction of each first frame 231 and the second frame 232 is used to set the discharge electrode 210; or, as... Figure 5 As shown, the portion of the first frame 231 located between the two second frames 232 is used to set the discharge electrode 210.

[0069] Optionally, such as Figure 6 As shown, the discharge electrode 210 is constructed in the shape of a needle tip.

[0070] Optionally, such as Figure 7As shown, the ionization device includes a plurality of discharge sections disposed on the first frame 231, and each discharge section includes a conductive section 211 disposed in a third direction and a discharge electrode 210 extending outward along one or both sides of the conductive section 211.

[0071] In this embodiment, the first frame 231 has a groove, and the transmission wires of the ion generator 212 are arranged in the groove. Furthermore, each conductive part 211 is connected to the transmission wire in the groove at the corresponding position. The ion generator 212 is electrically connected to the discharge electrode 210 through the conductive part 211, and then releases negative or positive ions through the discharge electrode 210.

[0072] Optionally, the third direction is perpendicular to the first direction.

[0073] Optionally, multiple conductive parts 211 are arranged at equal intervals. The spacing between adjacent conductive parts is d2.

[0074] In some embodiments, the device includes a housing 100, a temperature regulating device 110, and a water separation device 200. For example... Figure 8 As shown, the temperature regulating device 110 is disposed inside the housing 100 and is used to regulate the air temperature. The water separation device 200 is disposed inside the housing 100 and is used to separate water from the air. Furthermore, the distance between the water separation device 200 and the temperature regulating device 110 is x1; wherein 2mm ≤ x1 ≤ 40mm.

[0075] In this embodiment, by limiting the value of x1, the water separation effect of the water separation device 200 can be effectively improved, which is conducive to ensuring the cleaning effect of the temperature regulation device 110 in the self-cleaning mode.

[0076] Optionally, the water separation device 200 is located upstream of the temperature regulating device 110 along the airflow direction through the temperature regulating device 110.

[0077] Optionally, such as Figure 9 As shown, the distance between the water separation device 200 and the windward side surface of the temperature regulating device 110 is x11; where 2mm≤x11≤10mm.

[0078] Optionally, the water separation device 200 is located downstream of the temperature regulating device 110 along the airflow direction through the temperature regulating device 110.

[0079] Optionally, such as Figure 10 As shown, the distance between the water separation device 200 and the leeward side surface of the temperature regulating device 110 is x12; where 2mm≤x12≤13mm.

[0080] It should be noted that the airflow direction mentioned above refers to the airflow direction when the fan device 130 is rotating in the forward direction, that is, air enters from the air inlet 101 and flows out from the air outlet 102.

[0081] Optionally, the water separation device 200 includes an ionization device, which includes a plurality of discharge electrodes 210. The surface formed by the plurality of discharge electrodes 210 is called the first surface; the first surface is a plane, or a plurality of bent planes, or a curved surface; and x1 is the minimum distance between the first surface and the temperature regulating device 110.

[0082] In this embodiment, the discharge electrode 210 is disposed on the mounting frame 230. Different shapes of the mounting frame 230 result in multiple discharge electrodes 210 forming different first surfaces. For example, if the mounting frame 230 is a rectangular frame, the first surface is a plane. If the mounting frame 230 is an arc-shaped frame, the first surface is a curved surface. To make the water separation device suitable for different types of installation spaces, the specific shape of the mounting frame 230 is not limited here.

[0083] Optionally, x11 is the minimum distance between the first surface and the windward side of the temperature regulating device 110; x12 is the minimum distance between the first surface and the leeward side of the temperature regulating device 110.

[0084] In the above embodiments, within the range of x1, the values ​​of x11 and x12 are further limited for the water separation device 200 located upstream or downstream of the temperature regulation device 110, respectively, to obtain the optimal spatial position. This enhances the electric field effect between the discharge electrode 210 and the temperature regulation device 110, allowing water molecules and dust to become charged ions and be better adsorbed onto the surface of the temperature regulation device 110, thus further improving condensation and dehumidification efficiency.

[0085] In some embodiments, the device includes a housing 100, a temperature regulating device 110, and a water separation device 200. The housing 100 has a gas outlet. The temperature regulating device 110 is disposed within the housing 100 and is used to regulate the air temperature. The water separation device 200 is disposed within the housing 100 and is used to separate water from the air. The distance between the water separation device 200 and the gas outlet is x2, where 5mm ≤ x2 ≤ 80mm.

[0086] In this embodiment, by limiting the value of x2, the water separation effect of the water separation device 200 can be effectively improved, which is conducive to ensuring the cleaning effect of the temperature regulation device 110 in the self-cleaning mode.

[0087] Optionally, the gas flow port includes an air inlet 101. Along the airflow direction through the temperature regulating device 110, the air inlet 101 is located upstream of the temperature regulating device 110, and the water separation device 200 is located between the air inlet 101 and the temperature regulating device 110.

[0088] Optionally, such asFigure 9 As shown, the distance between the water separation device 200 and the air inlet 101 is x21; where 5mm≤x21≤10mm.

[0089] Optionally, the gas flow outlet includes an air outlet 102. Along the airflow direction through the temperature regulating device 110, the air outlet 102 is located downstream of the temperature regulating device 110, and the water separation device 200 is located between the air outlet 102 and the temperature regulating device 110.

[0090] Optionally, such as Figure 10 As shown, the distance between the water separation device 200 and the air outlet 102 is x22; where 5mm≤x22≤15mm.

[0091] It should be noted that the airflow direction mentioned above refers to the airflow direction when the fan device 130 is rotating in the forward direction, that is, air enters from the air inlet 101 and flows out from the air outlet 102.

[0092] Optionally, the water separation device 200 includes an ionization device, which includes a plurality of discharge electrodes 210. The surface formed by the plurality of discharge electrodes 210 is called the first surface; the first surface is a plane, or a plurality of bent planes, or a curved surface; and x2 is the minimum distance between the first surface and the gas flow port.

[0093] Optionally, x21 is the minimum distance between the first surface and the air inlet 101. x22 is the minimum distance between the first surface and the air outlet 102.

[0094] In the above embodiments, within the range of x2, the values ​​of x21 and x22 are further limited for the water separation device 200 located upstream or downstream of the temperature regulation device 110, respectively, to obtain the optimal spatial position. This enhances the electric field effect between the discharge electrode 210 and the temperature regulation device 110, allowing water molecules and dust to become charged ions and be better adsorbed onto the surface of the temperature regulation device 110, thus further improving condensation and frosting efficiency.

[0095] In some embodiments, the device includes a housing 100, a temperature regulating device 110, and a water separation device 200. The temperature regulating device 110 is disposed within the housing 100 and has a plurality of fins 111. The water separation device 200 is disposed within the housing 100 and is used to separate water from the air onto the surface of the temperature regulating device 110. Furthermore, lowering the temperature of the temperature regulating device 110 causes the water on its surface to condense into frost, and the distance between the frost layers growing on opposite sides of adjacent fins 111 is called the frost gap d6; in the case of frost formation, the difference between the fin spacing d5 and the frost gap d6 is greater than or equal to 0.4 mm.

[0096] In this embodiment, asFigure 11 As shown, the fin spacing d5 is fixed. The larger the difference between the fin spacing d5 and the frost gap d6, the thicker the frost layer. By controlling the temperature regulating device 110 and the water separation device 200, this difference is made greater than or equal to 0.4mm, which helps to ensure the cleaning effect of the temperature regulating device 110 in self-cleaning mode.

[0097] Optionally, multiple fins 111 are arranged parallel to each other and at equal intervals.

[0098] Optionally, the fin spacing d5 can range from 1mm to 2mm.

[0099] Optionally, when the relative humidity of the environment is less than 30%, the difference between the fin spacing d5 and the condensation gap d6 is greater than or equal to 0.4 mm.

[0100] Optionally, the difference between the fin spacing d5 and the frost gap d6 is greater than or equal to 1 mm.

[0101] Optionally, when the relative humidity of the environment is greater than or equal to 30%, the difference between the fin spacing d5 and the condensation gap d6 is greater than or equal to 1 mm.

[0102] Optionally, the device also includes a gap measurement module for measuring the value of the condensation gap d6. For example, the condensation gap d6 can be measured using a laser measuring device or a vision measuring device.

[0103] Optionally, the device also includes a humidity detection module for detecting the relative humidity of the environment. Based on the ambient humidity, the water separation device 200 and the temperature regulation device 110 are controlled to adjust the difference between the fin spacing d5 and the condensation gap d6, thereby ensuring the cleaning effect of the temperature regulation device 110 under different ambient humidity conditions.

[0104] In some embodiments, the device includes a housing 100, a temperature regulating device 110, and a water separation device 200. The temperature regulating device 110 is disposed within the housing 100 and has fins 111. The water separation device 200 is disposed within the housing 100 and is used to separate water from the air onto the surface of the temperature regulating device 110. Furthermore, lowering the temperature of the temperature regulating device 110 can cause the water on its surface to condense into frost; in the case of frost formation, fins 111 form frost sections; and the ratio of the distance d7 of the frost section to the fin width d8 is 0.1-1.

[0105] In this embodiment, by limiting the ratio of the frosting section to the fin width d8, the water separation effect of the water separation device 200 can be effectively improved, thereby helping to ensure the cleaning effect of the temperature regulation device 110 in the self-cleaning mode.

[0106] Optionally, such as Figure 11As shown, the temperature regulating device 110 has a windward side and a leeward side. The fin 111 includes a windward section 112, a middle section 113, and a leeward section 114. The windward section 112 is located on the windward side of the temperature regulating device 110; the leeward section 114 is connected to the windward section 112 and is located on the leeward side of the temperature regulating device 110; and the distance of the windward section 112 is equal to the distance of the leeward section 114. The two ends of the middle section 113 are connected to the windward section 112 and the leeward section 114 respectively, and are located between the windward and leeward sides of the temperature regulating device 110; and the distance of the middle section 113 is less than or equal to the distance of the windward section 112. The sum of the distances of the windward section 112, the middle section 113, and the leeward section 114 is the fin width d8. In this way, by arranging the positions and distances of the windward section 112, the middle section 113 and the leeward section 114, the fins 111 are made easier to condense and frost.

[0107] Alternatively, in the event of frost formation, due to the different positions of the three sections of fin 111, the windward section 112 is most prone to frost formation, and the frost layer gradually grows towards the leeward section 114. Therefore, the distance between the frost-forming sections formed on the windward section 112 is greater than or equal to the distance between the frost-forming sections formed on the leeward section 114.

[0108] Optionally, when the relative humidity of the environment is less than 30%, the ratio of the distance d7 of the frosting section to the fin width d8 is 0.1-1.

[0109] Optionally, the ratio of the distance d7 of the frosting section to the fin width d8 is 0.3-1.

[0110] Optionally, when the relative humidity of the environment is greater than or equal to 30%, the ratio of the distance d7 of the frosting section to the fin width d8 is 0.3-1.

[0111] Optionally, the device also includes a distance measurement module for measuring the distance d7 of the frosted section. For example, the distance d7 of the frosted section can be measured using a laser measuring device or a vision measuring device.

[0112] Through the above embodiments, the distance d7 of the frosting section and the fin width d8 are adjusted according to the ambient humidity control water separation device 200 and temperature regulation device 110, thereby ensuring the cleaning effect of temperature regulation device 110 under different ambient humidity conditions.

[0113] In some embodiments, the device includes a housing 100, a temperature regulating device 110, and a water separation device 200. The temperature regulating device 110 is disposed within the housing 100 and has fins 111. The water separation device 200 is disposed within the housing 100 and includes an ionization device comprising a plurality of adjacent discharge electrodes 210 spaced apart by a first distance. The distance between the water separation device 200 and the surface of the temperature regulating device 110 is a second distance, and the ratio between the first distance and the second distance is greater than or equal to 0.1.

[0114] In this embodiment, by limiting the ratio between the first spacing and the second spacing, the water separation effect of the water separation device 200 can be effectively improved, thereby helping to ensure the cleaning effect of the temperature regulation device 110 in the self-cleaning mode.

[0115] Optionally, the first spacing is 2mm-100mm. Here, the first spacing is d1 as mentioned above.

[0116] Optionally, the surface formed by the plurality of discharge electrodes 210 is called the first surface; the first surface is a plane, or a plurality of bent planes, or a curved surface; and the second spacing is the minimum distance between the first surface and the temperature regulating device 110. Here, the second spacing is x1 as described above.

[0117] Optionally, the second spacing is 2mm-40mm.

[0118] Optionally, the ratio between the first spacing and the second spacing is less than or equal to 10.

[0119] Optionally, the second spacing is the distance between the water separation device 200 and the windward side surface of the temperature regulating device 110. Here, the second spacing is x11 as mentioned above.

[0120] Optionally, the second spacing is the distance between the water separation device 200 and the leeward side surface of the temperature regulating device 110. Here, the second spacing is x12 as mentioned above.

[0121] The above embodiments achieve optimal spatial positioning by defining the first spacing, the second spacing, and the proportional relationship between them. This enhances the electric field effect between the discharge electrode 210 and the temperature control device 110, allowing water molecules and dust to be better adsorbed onto the surface of the temperature control device 110 after becoming charged ions, which is beneficial for further improving condensation and frosting efficiency.

[0122] In some embodiments, the device includes a housing 100, a temperature regulating device 110, and a water separating device 200. The housing 100 has an air inlet 101. The temperature regulating device 110 is disposed within the housing 100 and is used to regulate the air temperature. The water separating device 200 is disposed within the housing 100 and located at the air inlet 101, and is used to separate water from the air onto the surface of the temperature regulating device 110; wherein the separated water is used to clean the temperature regulating device 110.

[0123] In this embodiment, the water separation device 200 is located at the air inlet 101. The water separation device 200 separates water from the air onto the surface of the temperature regulating device 110, causing rapid condensation on the surface of the temperature regulating device 110. This effectively improves the condensation efficiency of the temperature regulating device 110, which is beneficial for ensuring the cleaning effect of the temperature regulating device 110 in self-cleaning mode.

[0124] Optionally, the air inlet 101 is equipped with a filter, and the water separation device 200 is installed within the filter. In this way, the water separation device 200 and the filter are used in combination.

[0125] Optionally, the filtration device includes a filter screen 120, which includes a first frame 121 arranged along a first direction; the water separation device 200 includes an ionization device, which includes a plurality of discharge electrodes 210 disposed on the first frame 121 for ionizing air to generate ions; water and dust in the air can combine with ions and be adsorbed onto the surface of the temperature regulating device 110.

[0126] Optionally, such as Figure 12 As shown, a primary filter structure 123 is provided on the side of the filter screen 120 away from the temperature regulating device 110, and a discharge electrode 210 is provided on the side of the filter screen 120 facing the temperature regulating device 110.

[0127] In this embodiment, the primary filter structure 123 includes a simple mesh filter, an activated carbon filter, or a HEPA filter. Outside air flows sequentially through the primary filter structure 123 to the electric field formed by the discharge electrode 210. The primary filter structure 123 filters out some dust. Fine dust particles that are not filtered out become charged ions when passing through the electric field and are adsorbed onto the surface of the temperature regulating device 110.

[0128] Optionally, a primary filter structure 123 is provided on the side of the filter screen 120 facing the temperature regulating device 110, and a discharge electrode 210 is provided on the side of the filter screen 120 away from the temperature regulating device 110.

[0129] In this embodiment, external air flows sequentially from the electric field formed by the discharge electrode 210 to the primary filter structure 123. When dust flows through the electric field, it becomes charged ions. Because the dust is charged, it gathers together and is thus more easily blocked and filtered by the primary filter structure 123.

[0130] Optionally, some or all of the discharge electrodes 210 are perpendicular to the filter screen 120.

[0131] Optionally, the first frame 121 has a groove, and the transmission wires of the ion generator 212 are arranged in the groove. Furthermore, each discharge electrode 210 is connected to the transmission wire in the corresponding groove, so that the ion generator 212 can release negative or positive ions through the discharge electrode 210.

[0132] Optionally, the filter 120 further includes a second frame 122. The second frame 122 is connected to the first frame 121 and is arranged along a second direction perpendicular to the first direction. The junction of the first frame 121 and the second frame 122 is used to house the discharge electrode 210, or the portion of the first frame 121 located between the two second frames 122 is used to house the discharge electrode 210.

[0133] In some embodiments, the device includes a housing 100, a temperature regulating device 110, a water separation device 200, and a fan device 130. The housing 100 has an air outlet 102. The temperature regulating device 110 is disposed within the housing 100 and is used to regulate the air temperature. Figure 10 As shown, the water separation device 200 is disposed inside the housing 100 and located between the temperature regulating device 110 and the air outlet 102, and is used to separate water from the air; the fan device 130 is disposed inside the housing 100 and is used to blow air sequentially toward the water separation device 200 and the temperature regulating device 110.

[0134] In this embodiment, the water separation device 200 is disposed between the temperature regulating device 110 and the air outlet 102. The water separation device 200 separates water from the air, and then the fan device 130 blows air sequentially towards the water separation device 200 and the temperature regulating device 110, thereby causing rapid condensation on the surface of the temperature regulating device 110. This effectively improves the condensation efficiency of the temperature regulating device 110, which is beneficial for ensuring the cleaning effect of the temperature regulating device 110 in self-cleaning mode.

[0135] Optionally, the housing 100 also has an air inlet 101; when the fan device 130 rotates in the forward direction, air is blown from the air inlet 101 to the temperature regulating device 110; when the fan device 130 rotates in the reverse direction, air is blown from the air outlet 102 to the water separation device 200 and the temperature regulating device 110 in sequence. Thus, in the self-cleaning mode, it is necessary to control the fan device 130 to rotate in the reverse direction.

[0136] Optionally, the water separation device 200 also includes a mounting frame 230, on which multiple discharge electrodes 210 are disposed. Tube sheets are provided on both sides of the temperature regulating device 110, and the two sides of the mounting frame 230 are respectively connected to the two tube sheets.

[0137] Optionally, the mounting frame 230 has clips on both sides and slots on both tube sheets, with the clips and slots fitting together so that both sides of the mounting frame 230 are respectively snapped onto the corresponding tube sheets. This snap-fit ​​structure makes the installation and disassembly of the mounting frame 230 very convenient.

[0138] In some embodiments, the device includes a housing 100, a temperature regulating device 110, and a water separating device 200. The temperature regulating device 110 is disposed within the housing 100 and is used to regulate the temperature of the air. The water separating device 200 is disposed within the housing 100 and includes an ionization device for ionizing air to generate ions; the ionization device includes a repulsive part for generating a repulsive force against the ions; and water and dust in the air, after combining with the ions, move towards the temperature regulating device 110 under the action of the repulsive force.

[0139] In this embodiment, an ionization device is used to ionize the air to generate ions. Water molecules and dust in the air combine with these ions, becoming charged ions. Furthermore, under the repulsive force of the repulsive part, the water molecules and dust rapidly move towards the temperature regulating device 110 and are then adsorbed onto its surface. Thus, the condensation and dehumidification efficiency of the temperature regulating device 110 is effectively improved by the repulsive part.

[0140] Optionally, the ionization device includes n discharge electrodes 210, which are used to ionize air to generate ions. Wherein, n ≥ 1. The discharge electrodes 210 are connected to a power source via an ion generating device 212.

[0141] Optionally, such as Figure 13 As shown, the repulsive part includes a housing 220. The housing 220 is disposed around the discharge electrode 210 and connected to a power source, and the polarity of the power source connected to the housing 220 is the same as the polarity of the power source connected to the discharge electrode 210.

[0142] For example, the discharge electrode 210 is connected to the negative terminal of the power supply to generate negative ions, and the casing 220 is also connected to the negative terminal of the power supply. Water molecules and dust in the air combine with the negative ions, becoming charged negative ions. Furthermore, under the influence of the electric field formed by the casing 220, the water molecules and dust move towards the temperature regulating device 110 due to the electric field force.

[0143] In another example, the discharge electrode 210 is connected to the positive terminal of the power supply to generate positive ions, and the casing 220 is also connected to the positive terminal of the power supply. Water molecules and dust in the air combine with the positive ions, becoming charged positive ions. Furthermore, under the influence of the electric field generated by the casing 220, the water molecules and dust move towards the temperature regulating device 110 due to the electric field force.

[0144] Optionally, the power supply connected to the housing 220 and the power supply connected to the discharge electrode 210 are the same power supply.

[0145] Optionally, the number of enclosures 220 is m, where 1 ≤ m ≤ n.

[0146] For example, if the number of housings 220 is the same as the number of discharge electrodes 210, i.e., m = n, then the installation method is that one discharge electrode 210 is set inside one housing 220, such as... Figure 14 As shown.

[0147] Another example is that if the number of housings 220 is less than the number of discharge electrodes 210, i.e., m < n, then the installation scheme is to arrange multiple discharge electrodes 210 within one housing 220. For example... Figure 15 As shown, two discharge electrodes 210 are arranged inside a housing 220, where m = 1 / 2n.

[0148] This disclosure also provides an ionization device, such as... Figure 13 As shown, the ionization device includes a discharge electrode 210 and a housing 220. The discharge electrode 210 is connected to a power source to ionize air and generate ions. The housing 220 is arranged around the discharge electrode 210 and connected to a power source, and the polarity of the power source connected to the housing 220 is the same as the polarity of the power source connected to the discharge electrode 210. Water and dust in the air can combine with the ions, and after combining, they repel each other from the housing 220.

[0149] In this embodiment, the discharge electrode 210 ionizes the air to generate ions. Water molecules and dust in the air combine with these ions, becoming charged ions. Furthermore, since the power supplies connected to the casing 220 and the discharge electrode 210 have the same polarity, the water molecules and dust repel each other under the electric field generated by the casing 220. This also reduces the amount of dust accumulating around the discharge electrode 210.

[0150] Optionally, the housing 220 is constructed in a conical or hemispherical shape, with the bottom surface facing upwards as the upper end face. The bottom diameter d3 of the housing 220 is 0.5mm-2mm.

[0151] Optionally, the housing 220 is constructed as a cylinder. The diameter of the base of the housing 220 is 10mm-20mm. The height of the housing 220 is 1mm-10mm.

[0152] Optionally, part or all of the discharge electrode 210 is located inside the housing 220.

[0153] For example, such as Figure 14As shown, when the discharge end of the discharge electrode 210 extends beyond the upper surface of the cover 220, the discharge electrode 210 is partially located inside the cover 220. With the discharge end of the discharge electrode 210 extending beyond the cover 220, the release range of the ions generated at the discharge end is wider. Given a fixed amount of ion release, it can cover a larger surface area of ​​the temperature control device, resulting in a thinner frost layer when frosting occurs.

[0154] Another example is, such as Figure 15 As shown, when the discharge end of the discharge electrode 210 is located below the upper end face of the housing 220, the discharge electrode 210 is entirely located inside the housing 220. With the discharge end of the discharge electrode 210 inside the housing 220, the release range of the ions generated at the discharge end is confined. Given a fixed amount of ion release, the surface area it can cover for the temperature control device is relatively small, resulting in a thicker frost layer when frosting occurs.

[0155] In both of the above cases, the distance d4 between the discharge end of the discharge electrode 210 and the upper end surface is 1mm-3mm. This distance setting allows the water molecules and dust that have become charged ions to have a good repulsive effect with the casing 220.

[0156] Optionally, the surface of the cover 220 has multiple small holes. The total area of ​​the multiple small holes is less than or equal to half the area of ​​the cover 220. The multiple small holes may be the same size or different sizes. In this way, by making small holes and setting an appropriate area, the obstruction of the cover 220 to the circulating air can be reduced, which is conducive to the rapid passage of water molecules and dust.

[0157] In some embodiments, such as Figure 16 As shown, the device includes a housing 100, a temperature regulating device 110, a water separating device 200, and a moving device 300. The temperature regulating device 110 is disposed within the housing 100 and is used to regulate the air temperature. The water separating device 200 is disposed within the housing 100 and is used to separate water from the air onto the surface of the temperature regulating device 110. The moving device 300 is connected to the water separating device 200 and is used to drive the water separating device 200 to move relative to the temperature regulating device 110.

[0158] In this embodiment, the relative positions of the water separation device 200 and the temperature regulation device 110 are adjusted by the driving device, thereby improving the condensation effect. This helps to ensure the cleaning effect of the temperature regulation device 110 in self-cleaning mode.

[0159] Optionally, the moving device 300 includes a first moving part. The first moving part is used to drive the water separation device 200 to move approximately relative to the temperature regulating device 110.

[0160] In this embodiment, the device includes an air conditioner, and the temperature regulating device 110 includes a heat exchanger. With continuous use of the air conditioner, the accumulation of dirt varies at different locations on the surface of the heat exchanger. Therefore, the first moving part can move the water separation device 200 to areas with severe dirt accumulation, thereby improving the condensation efficiency in that area, increasing the area or thickness of the frost layer, and thus improving the cleaning effect in that area.

[0161] Optionally, the water separation device 200 includes a mounting frame 230; the first moving part includes a first slide rail 310, a first slider 311, and a first driving part. The first slide rail 310 extends in the left-right direction toward the temperature regulating device 110; one side of the first slider 311 is connected to the mounting frame 230, and the other side is slidably connected to the first slide rail 310; and when the first slider 311 slides along the first slide rail 310, it drives the mounting frame 230 to move synchronously. The first driving part is used to drive the first slider 311 to slide along the first slide rail 310.

[0162] Optionally, the first drive unit includes a first motor and a first rack. The first motor is disposed on the first slider 311 or the mounting frame 230; the first rack is arranged along the extension direction of the first slide rail 310, and the drive shaft gear of the first motor meshes with the first rack. Thus, when the first motor starts, the drive gear moves along the first rack. At the same time, the first motor drives the first slider 311 to move synchronously, and the first slider 311 drives the mounting frame 230 to move synchronously.

[0163] For example, two first sliders 311 are provided on the first slide rail 310, and the two sides of the mounting frame 230 are respectively connected to the two first sliders 311. Furthermore, the first motor is fixed to one of the first sliders 311, thereby driving the mounting frame 230 to move left and right relative to the temperature regulating device 110.

[0164] Optionally, the moving device 300 further includes a second moving part for driving the water separation device 200 to move back and forth relative to the temperature regulating device 110.

[0165] In this embodiment, the smaller the distance between the water separation device 200 and the temperature regulating device 110, the shorter the movement distance of charged water molecules and dust, allowing them to be adsorbed onto the surface of the temperature regulating device 110 more quickly, forming a thicker frost layer, which is beneficial for cleaning dirt with strong adhesion. Conversely, the larger the distance between the water separation device 200 and the temperature regulating device 110, the greater the movement range of charged water molecules and dust, allowing them to be adsorbed onto the surface of the temperature regulating device 110 over a larger area, forming a larger frost layer, which is beneficial for cleaning dirt over a larger area. Thus, the distance between the water separation device 200 and the temperature regulating device 110 can be reasonably adjusted by the second moving part according to the dirt condition of the temperature regulating device.

[0166] Optionally, the second moving part includes a second slide rail 320, a second slider 321, and a second driving part. The second slide rail 320 extends towards the front-rear direction of the temperature regulating device 110; one side of the second slider 321 is connected to the first slide rail 310, and the other side is slidably connected to the second slide rail 320; the second driving part drives the second slider 321 to slide along the second slide rail 320. In this way, the moving device 300 can drive the water separation device 200 to move left and right via the first moving part, and can also drive the water separation device 200 to move back and forth via the second moving part.

[0167] Optionally, the second drive unit includes a second motor and a second rack. The second motor is disposed on the second slider 321; the second rack is arranged along the extending direction of the second slide rail 320, and the drive shaft gear of the second motor meshes with the second rack. Thus, when the second motor starts, the drive gear moves along the second rack. Simultaneously, the second motor drives the second slider 321 to move synchronously, the second slider 321 drives the first slide rail 310 to move synchronously, and the first slide rail 310 drives the mounting frame 230 to move synchronously.

[0168] For example, two second slide rails 320 are arranged opposite to each other, and each second slide rail 320 is provided with a second slider 321. The two ends of the first slide rail 310 are respectively connected to the two second sliders 321. Furthermore, a second motor is fixed to one of the second sliders 321, thereby driving the mounting frame 230 to move back and forth relative to the temperature regulating device 110.

[0169] Optionally, the second moving part includes a second slide rail 320, a second slider 321, and a second driving part. The second slide rail 320 extends in the front-rear direction toward the temperature regulating device 110; one side of the second slider 321 is connected to the mounting frame 230, and the other side is slidably connected to the second slide rail 320; the second driving part drives the second slider 321 to slide along the second slide rail 320. In this way, the moving device 300 can drive the water separation device 200 to move back and forth via the second moving part.

[0170] Understandably, in the above embodiments, the lengths of the first slide rail 310 and the second slide rail 320 are adjusted according to the internal space of the air conditioner. Furthermore, regardless of whether the water separation device 200 and the moving device 300 are located downstream of the temperature regulating device 110, the distance between the water separation device 200 and the temperature regulating device 110 changes synchronously during the movement of the water separation device 200 along the second slide rail 320, and the distance range is always maintained at 2mm≤x11≤10mm and 2mm≤x12≤13mm.

[0171] In some embodiments, such as Figure 17As shown, the device includes a housing 100, a temperature regulating device 110, a filter screen 120, and two water separation devices 200. The housing 100 has an air inlet 101 and an air outlet 102; the temperature regulating device 110 is disposed inside the housing 100, and the filter screen 120 is disposed at the air inlet 101; the two water separation devices 200 are disposed inside the housing 100; the first water separation device 200 is located upstream of the temperature regulating device 110 and is used to separate water from the air onto the surface of the temperature regulating device 110 and the filter screen 120; the second water separation device 200 is located downstream of the temperature regulating device 110 and is used to separate water from the air onto the surface of the temperature regulating device 110.

[0172] In this embodiment, the airflow path is: filter 120, first water separator 200, temperature control device 110, second water separator 200, and air outlet 102. When air flows through the two water separators 200, the water separators 200 can condense water from the air onto the surface of the temperature control device 110, causing rapid condensation on the surface of the temperature control device 110. This effectively improves the condensation efficiency of the temperature control device 110, which is beneficial for ensuring the cleaning effect of the temperature control device 110 in self-cleaning mode. Furthermore, when air flows through the first water separator 200, it can also condense water from the air onto the filter 120, thereby cleaning the filter 120.

[0173] Optionally, the equipment includes an air conditioner, and the temperature regulating device 110 includes a heat exchanger.

[0174] Optionally, the distance between the first water separation device 200 and the windward side surface of the temperature regulating device 110 is x11; the distance between the second water separation device 200 and the leeward side surface of the temperature regulating device 110 is x12; and x11 = x12. When there is only one water separation device 200, the ranges of x11 and x12 are as described above. In this embodiment, when there are two water separation devices 200, the ranges of their values ​​are 2mm ≤ x11 = x12 ≤ 10mm.

[0175] Optionally, the distance between the first water separation device 200 and the windward side surface of the temperature regulating device 110 is x11; the distance between the first water separation device 200 and the air inlet 101 is x21; and x11 > x21.

[0176] In this embodiment, when there is only one water separation device 200, the value ranges of x11 and x21 are as described above. In this embodiment, when there are two water separation devices 200, the value ranges of x11 and x21 are 5mm ≤ x21 < x11 ≤ 10mm. Although x11 is relatively large, the amount of water separated to the temperature regulating device 110 can be guaranteed by the airflow from the fan device 130. x21 is relatively small, which helps to ensure the amount of water separated to the filter screen 120 by reducing the power of the fan device 130.

[0177] Optionally, the device also includes two moving devices 300. The two moving devices 300 are respectively connected to the two water separation devices 200; the moving devices 300 are used to drive the corresponding water separation device 200 to move relative to the temperature regulating device 110.

[0178] In this embodiment, the structure of the moving device 300 is as described in the previous embodiment and will not be repeated. Furthermore, the moving range of the two water separation devices 200 always maintains x11 = x12 and x11 > x21.

[0179] Optionally, the water separation device 200 includes an ionization device. The ionization device includes an ion generator 212 and multiple discharge electrodes 210. The discharge electrodes 210 are used to ionize air and generate ions. Water molecules and dust in the air combine with the ions and can be adsorbed onto the surface of the temperature regulating device 110. The discharge electrodes 210 are connected to a power source via the ion generator 212; and the ions released by the two water separation devices 200 have the same polarity.

[0180] In this embodiment, when air flows through the water separation device 200, water molecules and dust in the air combine with ions to become charged ions. Furthermore, the ions released by the two water separation devices 200 have the same polarity, causing the charged ions to move towards the temperature regulating device 110, which is beneficial for adsorption. A water separation device 200 is installed upstream and downstream of the temperature regulating device 110, which can be considered as two-stage capture of water molecules and dust. When air flows through the first water separation device 200, most of the water molecules and dust in the air become charged ions, while a small portion does not and continues to move along the flow path. At this time, the portion of water molecules and dust that become charged ions is adsorbed onto the surface of the temperature regulating device 110, which is called the first capture. As the air continues to flow through the second water separation device 200, the water molecules and dust that were not initially captured become charged ions and are adsorbed onto the surface of the temperature regulating device 110, which is called the second capture. Thus, by capturing water molecules and dust twice, the condensation efficiency of the temperature regulating device 110 is effectively improved.

[0181] Optionally, both the filter 120 and the temperature regulating device 110 are made of conductive material; such as Figure 18As shown, the discharge electrodes 210 of the two water separation devices 200 are energized, and the temperature regulating device 110 and the filter screen 120 are grounded; and, in the case of air ionization, the temperature of the temperature regulating device 110 is reduced so that water or frost for cleaning is condensed on its surface; wherein, the ions generated by the first water separation device 200 are partially adsorbed onto the filter screen.

[0182] In this embodiment, when air flows through the first water separation device 200, water molecules and dust particles in the air combine with ions to become charged ions. Furthermore, since the filter screen 120 is made of conductive material and grounded, a first monopolar electric field is formed between the discharge electrode 210 and the temperature regulating device 110, and a second monopolar electric field is formed between the discharge electrode 210 and the filter screen 120. Thus, charged ions can be adsorbed onto the temperature regulating device 110 along the first monopolar electric field, thereby cleaning the temperature regulating device 110 in conjunction with the self-cleaning mode. Charged ions can also be adsorbed onto the filter screen 120 along the second monopolar electric field, which induces an electrostatic effect on the filter screen 120, thereby improving its ability to filter particulate matter, and can also cause condensation on the surface of the filter screen 120, thus cleaning dust.

[0183] Optionally, such as Figure 19 As shown, both the filter screen 120 and the temperature regulating device 110 are made of conductive material; the discharge electrodes 210 of the two water separation devices 200 are connected to the temperature regulating device 110 with opposite polarities, while the filter screen 120 and the temperature regulating device 110 are connected to the same polarity; and, in the case of air ionization, the temperature of the temperature regulating device 110 is reduced so that water or frost for cleaning condenses on its surface; wherein, the ions generated by the first water separation device 200 are partially adsorbed onto the filter screen 120.

[0184] In this embodiment, a first opposite-charge electric field is formed between the discharge electrode 210 and the temperature regulating device 110, and a second opposite-charge electric field is formed between the discharge electrode 210 and the filter screen 120. When air flows through the first water separation device 200, charged ions can be adsorbed onto the temperature regulating device 110 along the first opposite-charge electric field, or onto the filter screen 120 along the second opposite-charge electric field.

[0185] Optionally, the two water separation devices 200, the temperature control device 110, and the filter screen 120 are connected to the same power source.

[0186] Optionally, the device also includes a fan unit 130. The fan unit 130 is disposed inside the housing 100, and the number of ions adsorbed onto the filter screen 120 can be adjusted by controlling the power of the fan unit 130.

[0187] In this embodiment, after air flows through the first water separation device 200, water molecules and dust in the air combine with ions to become charged ions. Under the influence of the electric field, these charged ions have two directions of movement. When the fan device 130 is running at normal power, most of the charged ions move towards the temperature regulating device 110 due to the blowing force. When the power of the fan device 130 is reduced, the number of charged ions moving towards the filter 120 increases because the wind force is weakened while the electric field force remains unchanged, thereby increasing the condensation efficiency of the filter 120. For example, when the air conditioner is operating in the condensation stage of the self-cleaning mode, if it is necessary to clean the filter 120, the power of the fan device 130 can be reduced.

[0188] Combination Figure 20 As shown, this disclosure provides a control method for self-cleaning an air conditioner, including:

[0189] S101, the processor controls the air conditioner to run in self-cleaning mode and starts the water separation device.

[0190] S102, when the air conditioner is running in self-cleaning mode, the processor controls the shut-off of the water separation device according to the gap between the heat exchanger fins.

[0191] The control method for self-cleaning of air conditioners provided in this disclosure, when the air conditioner is operating in self-cleaning mode, can compensate for the self-cleaning mode by operating a water separation device, thereby improving the condensation efficiency and frosting efficiency of the heat exchanger. Simultaneously, by analyzing the fin gap of the heat exchanger, it can be determined whether the condensation or frosting amount meets the standard, and the water separation device can be controlled to close in time when the standard is met, thus ensuring the energy-saving effect of the water separation device. Under the action of the water separation device, more water molecules are adsorbed onto the surface of the heat exchanger, thereby increasing the amount of frosting on the surface of the heat exchanger, which is beneficial to improving the self-cleaning effect of the air conditioner.

[0192] Optionally, the processor controls the shutdown of the water separation device based on the heat exchanger fin gap, including: when the heat exchanger fin gap is less than or equal to a fin gap threshold, the processor controls the water separation device to shut down. Thus, when the heat exchanger fin gap is less than or equal to the fin gap threshold, it indicates that as condensation or frost accumulates on the heat exchanger surface, the gap between adjacent fins has decreased to below the fin gap threshold. At this point, the condensation or frost level of the heat exchanger meets the standard, therefore the water separation device is controlled to shut down promptly, thereby ensuring the energy-saving effect of the water separation device.

[0193] And / or,

[0194] Optionally, the processor controls the shutdown of the water separation device based on the heat exchanger fin gap, including: when the change in the heat exchanger fin gap is greater than or equal to a preset gap change value, the processor controls the water separation device to shut down. Thus, when the change in the heat exchanger fin gap is greater than or equal to the preset gap change value, it indicates that with the continuous accumulation of condensation or frost on the heat exchanger surface, the change in the gap between adjacent fins exceeds the preset gap change value. At this point, the condensation or frost amount of the heat exchanger meets the standard, therefore the water separation device is controlled to shut down in a timely manner, thereby ensuring the energy-saving effect of the water separation device.

[0195] Optionally, the processor obtains the fin gap threshold by determining the fin gap threshold based on the opening node of the water separation device. Thus, embodiments of this disclosure can set different fin gap thresholds for different opening nodes of the water separation device, thereby better reflecting the actual condensation or frosting effect of the heat exchanger.

[0196] Optionally, the processor determines the preset fin gap based on the activation node of the water separation device, including: when the activation node is in the condensation stage, the processor determines the fin gap threshold as a first gap threshold; or, when the activation node is in the frosting stage, the processor determines the fin gap threshold as a second gap threshold. The first gap threshold is greater than the second gap threshold. Thus, if the water separation device is activated in the condensation stage, it can be shut down when the heat exchanger condensation level meets the standard. In this case, a relatively large first gap threshold can be set as the condition for self-cleaning compliance, ensuring the condensation effect of the heat exchanger. Conversely, if the water separation device is activated in the frosting stage, it can be shut down when the heat exchanger frost level meets the standard. Considering that the volume of condensate expands after condensation into frost, causing the gap between adjacent fins to further shrink, a relatively smaller second gap threshold can be set as the condition for self-cleaning compliance, ensuring the frosting effect of the heat exchanger.

[0197] Optionally, the processor obtains the preset gap change value in the following manner: the processor determines the preset gap change value based on the heat exchanger clogging information. Thus, embodiments of this disclosure can set different preset gap change values ​​for heat exchanger clogging information, thereby better meeting the condensation or frost requirements of the heat exchanger.

[0198] Optionally, the processor determines a preset gap change value based on the heat exchanger clogging information, including: when the heat exchanger clogging information indicates severe clogging, the processor determines the preset gap change value to be a first gap change value; or, when the heat exchanger clogging information indicates slight clogging, the processor determines the preset gap change value to be a second gap change value. The first gap change value is greater than the second gap change value. Thus, when the heat exchanger is severely clogged, the amount of dust to be cleaned is large, and the corresponding requirements for condensation and frost are also higher. In this case, a relatively large first gap change value can be set as the judgment condition for self-cleaning compliance, thereby increasing the amount of condensation or frost on the heat exchanger surface to match the large amount of dust. Conversely, when the heat exchanger is slightly clogged, the amount of dust to be cleaned is small, and the corresponding requirements for condensation and frost are relatively low. Therefore, a relatively small second gap change value can be set as the judgment condition for self-cleaning compliance, controlling the water separation device to shut down earlier, thereby taking into account the energy-saving effect of the water separation device.

[0199] Combination Figure 21 As shown in the embodiments of this disclosure, another control method for self-cleaning of air conditioners is provided, including:

[0200] S201, the processor controls the air conditioner to run in self-cleaning mode and starts the water separation device.

[0201] S202, the processor determines the operating parameters of the water separation device based on environmental operating conditions and / or heat exchanger clogging information.

[0202] S203, the processor controls the water separation device to operate according to these operating parameters.

[0203] S204, when the air conditioner is running in self-cleaning mode, the processor controls the shut-off of the water separation device according to the gap between the heat exchanger fins.

[0204] The control method for self-cleaning of air conditioners provided in this disclosure addresses the problem of slow condensation rates on heat exchanger surfaces under harsh environments by controlling the operating parameters of the water separation device in conjunction with environmental condition information. Furthermore, to address the problem of insufficient frost formation on the heat exchanger surface when severe clogging occurs, the operating parameters of the water separation device can be controlled in conjunction with heat exchanger clogging information. Therefore, this disclosure can reasonably compensate for the self-cleaning mode of the air conditioner, thereby improving the condensation and frost formation efficiency of the heat exchanger and enhancing the self-cleaning effect of the air conditioner.

[0205] Optionally, the processor determines the operating parameters of the water separation device based on environmental condition information, including: determining the operating parameters of the water separation device based on humidity, including: determining the operating parameters of the water separation device as a first operating parameter when the current ambient humidity is less than a preset ambient humidity; or, determining the operating parameters of the water separation device as a second operating parameter when the current ambient humidity is greater than or equal to a preset ambient humidity. The water separation capacity corresponding to the first operating parameter is greater than the water separation capacity corresponding to the second operating parameter. Thus, when the indoor ambient humidity is low, it is not conducive to the self-cleaning condensation process of the air conditioner, which may result in slow condensation efficiency and low condensation volume on the heat exchanger surface. By setting a relatively larger first operating parameter, this embodiment of the present disclosure can appropriately enhance the water separation capacity of the water separation device to compensate more for the self-cleaning mode of the air conditioner, thereby improving the condensation efficiency and frosting efficiency of the heat exchanger. When the indoor ambient humidity is high, the self-cleaning process of the air conditioner itself can achieve better condensation and frosting effects. Therefore, this embodiment of the present disclosure sets a relatively smaller second operating parameter to appropriately reduce the operating energy consumption of the water separation device, thereby ensuring the self-cleaning effect of the air conditioner while further considering the energy-saving effect of the water separation device.

[0206] And / or,

[0207] Optionally, the processor determines the operating parameters of the water separation device based on the heat exchanger clogging information, including: determining the operating parameters of the water separation device as a third operating parameter when the heat exchanger clogging information indicates severe clogging; or determining the operating parameters of the water separation device as a fourth operating parameter when the heat exchanger clogging information indicates slight clogging. The water separation capacity corresponding to the third operating parameter is greater than that corresponding to the fourth operating parameter. Thus, when the heat exchanger is severely clogged, the amount of dust to be cleaned is greater, and the corresponding requirements for condensation and frost are also higher. By controlling the water separation device to operate with the more powerful third operating parameter, this embodiment of the present disclosure can better utilize the water separation device to more fully compensate for the self-cleaning process of the air conditioner, thereby increasing the amount of frost on the heat exchanger surface to match the larger amount of dust. When the heat exchanger is slightly clogged, the amount of dust to be cleaned is small, and the air conditioner's own self-cleaning process can achieve a better frost effect and wash away most of the dust during the defrosting stage. By controlling the water separation device to operate with a fourth operating parameter that consumes less energy, the present invention can reduce the working energy consumption of the water separation device, thereby avoiding energy waste caused by the water separation device operating at saturation, and further achieving energy-saving effects.

[0208] Optionally, the operating parameters of the water separation device include one or more of the following: power supply, voltage supply, and number of discharge electrodes. Thus, by controlling the parameters related to the discharge electrodes, the embodiments of this disclosure can precisely control the operation of the water separation device to increase the amount of frost on the heat exchanger surface, which is beneficial for improving the self-cleaning effect of the air conditioner. At the same time, it can also avoid energy waste caused by the water separation device operating at saturation, thus contributing to energy-saving effects.
