[0048] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0049] Combination Figure 1-7 As shown, an embodiment of the present disclosure provides a device, including a temperature regulating device and a filter device 200, wherein the filter device 200 includes a plurality of discharge parts, and each discharge part includes a plurality of discharge electrodes 230. The discharge electrodes 230 are connected to electricity and the temperature regulating device is grounded, or the discharge electrodes 230 and the temperature regulating device are respectively connected to electricity with opposite polarities, so as to ionize the air; and when the air is ionized, the temperature of the temperature regulating device is reduced to condense water or frost for cleaning the surface of the temperature regulating device.

[0050] In this embodiment, when the discharge electrode 230 is connected to electricity and the temperature regulating device is grounded, a unipolar electric field is formed between the two; when the discharge electrode 230 and the temperature regulating device are connected to electricity of opposite polarity, a heterogeneous charge electric field is formed between the two. When air flows through a unipolar electric field or a heterogeneous charge electric field, water molecules and dust in the air become charged ions, and the charged ions move toward the temperature regulating device under the action of the electric field force. After the charged water molecules are adsorbed on the surface of the temperature regulating device, they condense quickly, and the charged dust and dirt on the surface of the temperature regulating device dissolve in the water. In addition, as the temperature of the temperature regulating device decreases, a frost layer is formed on the surface of the temperature regulating device. In this way, the condensation, dehumidification and frosting efficiency are effectively improved, which makes it easier to use water or frost to clean the surface of the temperature regulating device, while also playing a role in cleaning dust in the air, and the charged ions can also play a sterilizing role.

[0051] In this embodiment, when the temperature regulating device is powered on, water molecules condense on the surface of the temperature regulating device to form a water film, which is polarized by the electric field. A stronger electric field is formed around the water film, which absorbs more surrounding water molecules, thereby further improving the condensation efficiency.

[0052] In this embodiment, when the discharge electrode 230 is connected to the negative pole of the power supply through the ion generator, negative ions are generated. When the discharge electrode 230 is connected to the positive pole of the power supply through the ion generator, positive ions are generated. Here, the power supply polarity of the ion generator is adjusted according to the electric field requirement.

[0053] For example, Figure 2 As shown, the discharge electrode 230 is connected to the negative pole of the power supply through the ion generator and generates negative ions, and the temperature adjustment device is made of a conductive material and connected to the positive pole of the power supply. At this time, a heterogeneous electric field is formed between the discharge electrode 230 and the temperature adjustment device. When the air flows through the electric field, water molecules and dust in the air become charged negative ions, and the charged negative ions move and are adsorbed to the surface of the temperature adjustment device.

[0054] In another exemplary embodiment, the discharge electrode 230 is connected to the positive electrode of the power supply through the ion generator and generates positive ions, and the temperature adjustment device is made of a conductive material and connected to the negative electrode of the power supply. At this time, a heterogeneous electric field is formed between the discharge electrode 230 and the temperature adjustment device, and when the air flows through the electric field, the water molecules and dust in the air become charged positive ions, and the charged positive ions move and are adsorbed to the surface of the temperature adjustment device.

[0055] Another exemplary example is, Figure 3 As shown, the discharge electrode 230 is connected to the negative electrode of the power supply through the ion generator and generates negative ions, and the temperature adjustment device is made of a conductive material and is grounded. At this time, a monopolar electric field is formed between the discharge electrode 230 and the temperature adjustment device. When the air flows through the electric field, water molecules and dust in the air become charged negative ions, and the charged negative ions move and are adsorbed to the surface of the temperature adjustment device.

[0056] In another exemplary embodiment, the discharge electrode 230 is connected to the positive electrode of the power supply through the ion generator and generates positive ions, and the temperature adjustment device is made of a conductive material and is grounded. At this time, a monopolar electric field is formed between the discharge electrode 230 and the temperature adjustment device, and when the air flows through the electric field, the water molecules and dust in the air become charged positive ions, and the charged positive ions move and adsorb to the surface of the temperature adjustment device.

[0057] In some embodiments, the filter device 200 includes a filter screen and a plurality of discharge parts. The filter screen includes a first frame 210 arranged along a first direction. The plurality of discharge parts are arranged on the first frame 210 to ionize the air to generate ions; each discharge part includes a conductive part 220 arranged along a third direction and a discharge electrode 230 connected to the conductive part 220, and the distance d between adjacent discharge parts is 1 mm-100 mm.

[0058] In this embodiment, the discharge electrode 230 can ionize the air to generate positive ions or negative ions. When the air flows through the filter, the water molecules and dust in the air become charged ions, which facilitates the adsorption and collection of water molecules and dust, and can also play a role in ion sterilization.

[0059] In this embodiment, the discharge portion includes a conductive portion 220 and a discharge electrode 230.

[0075] In this embodiment, a plurality of first frames 210 are parallel to each other, each first frame 210 is provided with a plurality of discharge parts, and the discharge parts on adjacent first frames 210 correspond to each other. The spacing between adjacent first frames 210 is the same or different. Preferably, the spacing between adjacent first frames 210 is the same.

[0076] Optionally, the first frame 210 is provided with a plurality of discharge parts on one side or both sides in the third direction.

[0077] Exemplarily, three first skeletons 210 are arranged in sequence along the third direction. A plurality of discharge parts are provided on one side of the first first skeleton 210, and the conductive parts 220 of the plurality of discharge parts face the second first skeleton 210. A plurality of discharge parts are provided on both sides of the second first skeleton 210, and the conductive parts 220 of the discharge parts on one side face the first first skeleton 210, and the conductive parts 220 of the discharge parts on the other side face the third first skeleton 210. A plurality of discharge parts are provided on one side of the third first skeleton 210, and the conductive parts 220 of the plurality of discharge parts face the second first skeleton 210.

[0078] Optionally, the plurality of discharge parts on adjacent first frames 210 correspond to each other, and the conductive parts 220 of the corresponding discharge parts are connected, such as Figure 4 shown.

[0079] Optionally, the plurality of discharge portions on adjacent first frames 210 correspond to each other, and the conductive portions 220 of the corresponding discharge portions are spaced apart, such as Figure 5 shown.

[0080] Optionally, a plurality of discharge parts on the same first frame 210 are connected in series, and a plurality of discharge parts on different first frames 210 are connected in series or in parallel.

[0081] In this embodiment, the first frame 210 is provided with a wire slot, and the transmission wires of the ion generator are arranged in the wire slot. Multiple discharge parts on the same first frame 210 are connected in series through the transmission wires, and multiple discharge parts on different first frames 210 are connected in series or in parallel through the transmission wires.

[0082] Optionally, the above-mentioned device includes an air conditioner, and the above-mentioned temperature adjustment device includes a heat exchanger 110. The heat exchanger 110 is generally made of a metal material with thermal and electrical conductivity such as copper, aluminum or steel.

[0083] Alternatively, if Figure 1 As shown, the air conditioner includes a shell 100, and a heat exchanger 110 and a fan are arranged in the shell 100. In addition, the shell 100 is provided with an air inlet 101 and an air outlet 102, and the filter device 200 is arranged to cover the air inlet 101. Among them, the length direction of the air inlet 101 is the first direction, and the width direction of the air inlet 101 is the third direction. A filtering structure is provided on the side of the filter away from the heat exchanger 110, and the filtering structure includes a simple mesh filter, an activated carbon filter or a HEPA filter. A discharge electrode 230 is provided on the side of the filter facing the heat exchanger 110. When air flows through the filtering structure, it can filter part of the dust. The fine dust that is not filtered out becomes charged ions when passing through the electric field and is adsorbed to the surface of the heat exchanger 110.

[0084] In the above embodiment, the air conditioner has a self-cleaning mode, which includes a condensation stage, a frosting stage, and a defrosting stage, and in the self-cleaning mode, a monopolar electric field or a heterogeneous charge electric field is formed between the discharge electrode 230 and the heat exchanger 110. First, in the condensation stage, the air conditioner is in cooling operation and the fan is running, and air enters the housing through the filter from the air inlet 101 and blows toward the heat exchanger 110. When the air passes through the electric field, the water molecules and dust in the air become charged ions, and the charged water molecules are adsorbed to the surface of the heat exchanger 110 and condense quickly. At this time, the dirt on the surface of the heat exchanger 110 and the charged dust in the air adsorbed by it dissolve into the water. Then, in the frosting stage, the air conditioner is in cooling operation and the fan is stopped, and the water on the surface of the heat exchanger 110 is frosted. Finally, in the defrosting stage, the air conditioner runs for heating and the fan stops, at which time the frost layer melts and dirt and dust are taken away from the surface of the heat exchanger 110 by the melted water, thus completing the self-cleaning of the heat exchanger 110 and the frosting efficiency can be improved by about 40%.

[0085] For example, Figure 2As shown, the discharge electrode 230 of the filter device 200 is connected to the negative pole of the power supply and generates negative ions, and the heat exchanger 110 is connected to the positive pole of the power supply. At this time, a heterogeneous electric field is formed between the discharge electrode 230 and the heat exchanger 110. In the condensation stage, the water molecules and dust in the casing that become charged negative ions are automatically adsorbed to the surface of the heat exchanger 110 under the action of the electric field force, and at this time, the fan is turned on to help blow the charged negative ions toward the heat exchanger 110.

[0086] Another exemplary example is, Figure 3 As shown, the discharge electrode 230 of the filter device 200 is connected to the negative pole of the power supply and generates negative ions, and the heat exchanger 110 is grounded. At this time, a monopolar electric field is formed between the discharge electrode 230 and the heat exchanger 110. In this way, the grounding of the heat exchanger 110 can improve the safety performance compared to connecting the positive pole of the power supply.

[0087] The air conditioner in the above embodiment also has a dehumidification mode, in which a monopolar electric field or a heterogeneous electric field is formed between the discharge electrode 230 and the heat exchanger 110. When dehumidifying, the air conditioner is in cooling operation and the fan is running, and air enters the housing through the filter screen from the air inlet 101 and blows toward the heat exchanger 110. When the air passes through the electric field, the water molecules in the air become charged ions, and the charged water molecules are adsorbed to the surface of the heat exchanger 110 and condense quickly. In this way, the dehumidification efficiency can be increased by 20%-30%.

[0088] Optionally, the air conditioner further comprises an electrode control module, which is used to control the power supply of part or all of the discharge electrodes 230 to be greater than or equal to 1 W. Here, the electrode control module adjusts the power supply of the discharge electrode 230 by controlling the ion generating device.

[0089] Exemplarily, the power supply power of the plurality of discharge electrodes 230 may be selected to be 1 W, 1.2 W, 1.3 W, 1.5 W, 1.6 W, 1.8 W, 1.9 W, 2 W, 2.1 W, 2.2 W, 2.5 W or 3 W.

[0090] Optionally, the electrode control module is also used to control the power supply voltage of part or all of the discharge electrodes 230 to be greater than or equal to 3 kV. Here, the electrode control module adjusts the power supply voltage of the discharge electrode 230 by controlling the ion generating device.

[0091] In this embodiment, when the distance between adjacent discharge parts is the first distance, the power supply voltage of the discharge electrode 230 is controlled to be the first voltage; when the distance between adjacent discharge parts is the second distance, the power supply voltage of the discharge electrode 230 is controlled to be the second voltage, wherein the first distance is greater than the second distance, and the first voltage is greater than the second voltage. That is, the larger the distance between adjacent discharge parts, the larger the power supply voltage of the discharge electrode 230. Preferably, the distance between adjacent discharge parts on the same filter device 200 is the same, so that it is easy to control.

[0092] Exemplarily, the supply voltage of the plurality of discharge electrodes 230 may be selected to be 3 kV, 3.1 kV, 3.2 kV, 3.3 kV, 3.5 kV, 3.6 kV, 3.7 kV, 3.8 kV, 4 kV, 4.5 kV or 5 kV.
