Description

Technical Field

[0001] This invention belongs to the field of air conditioner technology, and particularly relates to an air conditioner. Background Technology

[0002] Photocatalytic purification components include a photocatalyst, a carrier, and a light source. During the reaction, the light source excites the photocatalyst, generating high-energy electrons and holes, which react with the reactants on the catalyst surface. However, the simultaneous occurrence of hole-dominated oxidation and electron-dominated reduction reactions at the same photocatalyst contact point inevitably leads to electron-hole recombination and interference between reactions, resulting in the generation of byproducts and other adverse effects, thus reducing the actual efficiency of the photocatalytic reaction.

[0003] In related technologies, electrons are migrated through the action of current or electric field, leaving holes on the photocatalyst surface for oxidation reactions. While this improves the separation rate of electrons and holes, the migrated electrons do not undergo further conversion, and their gradual accumulation reduces the energy gradient, affecting the migration rate and resulting in only a slight increase in efficiency. Furthermore, reactions involving only holes have low rates. Therefore, the challenge lies in separating high-energy electrons and holes and enabling their rapid catalytic conversion at different sites to significantly improve the overall reaction rate.

[0004] In view of the above, this application is hereby submitted. Summary of the Invention

[0005] Compared to traditional photocatalytic modules, this application improves quantum efficiency and light energy utilization by constructing a gradient electric field and a cathode reduction region, thereby enhancing the catalytic conversion performance of gaseous pollutants.

[0079] This application discloses an air conditioner 100, with reference to... Figure 1 The air conditioner 100 includes an indoor unit.

[0080] Air conditioner 100 also includes an outdoor unit.

[0081] The outdoor unit is installed outdoors. The indoor and outdoor units are connected by pipes for refrigerant flow.

[0082] The indoor unit includes a housing 1. The housing 1 forms the outer outline of the indoor unit and houses the internal components of the indoor unit.

[0083] An air inlet 11 is formed on the housing 1. The air inlet 11 is used to allow indoor air to enter the housing 1. The air inlet 11 is provided with an air intake grille to filter the air and prevent larger impurities from entering the internal air duct 14.

[0084] An air outlet 12 is formed on the housing 1. The air outlet 12 is used to exhaust air from the housing 1. Indoor air enters the housing 1 through the air inlet 11 and is then blown out from the air outlet 12.

[0085] The air outlet 12 can extend along the length of the indoor unit, improving the aesthetics of the indoor unit of the air conditioner 100 and making the indoor unit of the air conditioner 100 more integrated. Of course, in other embodiments of this application, the positions of the air inlet 11 and the air outlet 12 can also be set in other positions, as long as the air intake and exhaust requirements can be met.

[0086] An air guide plate 13 is provided at the air outlet 12. The air guide plate 13 is movably provided at the air outlet 12 and is used to open and close the air outlet 12. When the air outlet 12 is opened by the air guide plate 13, the air guide plate 13 can also be configured to guide the heat-exchanged air discharged from the indoor unit through the air outlet 12.

[0087] The housing 1 contains multiple components that constitute a refrigeration cycle or a heating cycle.

[0088] In this application, indoor units include, but are not limited to, wall-mounted air conditioners 100, cabinet air conditioners 100, and ducted air conditioners.

[0089] This application uses a wall-mounted air conditioner 100 as an example for illustration. Other types of air conditioners 100 can have their structural positions adjusted based on the technical solutions of this application, as well as the installation of the purification component 4.

[0090] In some embodiments, the housing 1 is generally rectangular in shape.

[0091] The housing 1 includes at least an outer cover. The outer cover forms the basic frame of the air conditioner 100.

[0092] The housing 1 also includes a front panel. The front panel is mounted on the front side of the outer casing and forms the front surface of the housing 1.

[0093] It should be noted that the directions described in the text are based on the direction from which the user faces the indoor unit of air conditioner 100. Specifically, the side of the indoor unit of air conditioner 100 facing the user when in use is defined as the front side, and the opposite side is defined as the rear side. The left and right sides are distinguished by the direction from which the user faces the indoor unit of air conditioner 100. The upper and lower sides are defined by the upper and lower sides when the indoor unit of air conditioner 100 is generally working normally.

[0094] The housing 1 also includes a rear panel, which is mounted on the rear side of the outer cover for mounting the air conditioner 100 on the wall of an indoor space.

[0095] The outer casing includes a bottom surface. The bottom surface is configured to define the bottom structure of the air conditioner 100.

[0096] The outer casing includes side panels. The side panels are provided on both sides. They are located on both sides of the bottom surface along the length direction. They are used to form the sides of the air conditioner 100.

[0097] The outer casing includes a top surface. The top surface is configured to define the top appearance of the air conditioner 100.

[0098] In some embodiments, the front surface, top surface, and part of the bottom surface are integrated to facilitate a secure connection with the rear panel and side panels, forming a stable external structure of the air conditioner 100.

[0099] In some embodiments, the rear panel and part of the bottom surface are integrally formed to facilitate a secure connection with other components, forming a stable external structure of the air conditioner 100.

[0100] The indoor unit includes an indoor heat exchanger 2. The indoor heat exchanger 2 is installed inside the housing 1. The indoor heat exchanger 2 is used to exchange heat with the airflow entering the housing 1.

[0101] The indoor unit includes an indoor fan 3. The indoor fan 3 is installed inside the housing 1. The indoor fan 3 rotates to allow indoor air to enter the indoor housing 1. After exchanging heat with the indoor heat exchanger 2, the indoor air flows out of the indoor housing 1.

[0102] Reference Figure 2-3 The front panel, back panel, bottom surface, top surface, and side panels enclose and form an internal air duct 14.

[0103] In some embodiments, the indoor fan 3 is configured as a cross-flow fan.

[0104] The inner circumference of the rear panel has space for installing the indoor fan 3.

[0105] In some embodiments, the indoor heat exchanger 2 is arranged in a ring above the indoor fan 3.

[0106] The air conditioner 100 system in this application includes a compressor that can compress gaseous refrigerant at high temperature and high pressure and discharge the compressed gaseous refrigerant.

[0107] The compressor includes an intake port. Refrigerant flows into the compressor from the intake port to be compressed.

[0108] The compressor includes a discharge port. Refrigerant enters the compressor through the suction port, is compressed by the compressor, and is discharged through the discharge port.

[0109] The air conditioning system 100 includes an indoor heat exchanger 2 for exchanging heat with indoor air.

[0110] The air conditioning system 100 includes an outdoor heat exchanger for exchanging heat with outdoor air.

[0111] The air conditioning system 100 also includes a four-way valve. The first port of the four-way valve is connected to the compressor's discharge port. The second port of the four-way valve is connected to the compressor's suction port. The third port of the four-way valve is connected to the indoor heat exchanger 2. The fourth port of the four-way valve is connected to the outdoor heat exchanger.

[0112] The air conditioning system 100 also includes an electronic expansion valve. The electronic expansion valve is located between the outdoor heat exchanger and the indoor heat exchanger 2. The electronic expansion valve is used for throttling. It causes the high-temperature, high-pressure liquid refrigerant condensed in the condenser to expand into a low-pressure liquid refrigerant.

[0113] The indoor heat exchanger 2 and the outdoor heat exchanger function as either condensers or evaporators. When the indoor heat exchanger 2 functions as a condenser, the air conditioner 100 functions as a heater in heating mode. When the indoor heat exchanger 2 functions as an evaporator, the air conditioner 100 functions as a cooler in cooling mode.

[0114] The multi-split air conditioner 100 uses refrigerant flow to blow out air conditioning air that is higher than the indoor temperature, lower than the indoor temperature, or the same as the indoor temperature, in order to adjust the temperature and humidity of the indoor environment; or it uses the speed of the indoor fan 3 to adjust the air flow rate of the indoor environment.

[0115] When the air conditioner 100 is in cooling mode, the refrigerant from the compressor condenses in the outdoor heat exchanger. The condensed refrigerant then expands through the electronic expansion valve. The expanded condensate evaporates in the indoor heat exchanger 2. The evaporated refrigerant then circulates back to the compressor.

[0116] When the air conditioner is in heating mode (100), the refrigerant from the compressor flows through the indoor heat exchanger 2 and condenses. The condensed refrigerant then expands by passing through the electronic expansion valve. The expanded condensate evaporates through the outdoor heat exchanger. The evaporated refrigerant then circulates back to the compressor.

[0117] Reference Figure 3 The air conditioner 100 includes a purification component 4. The purification component 4 is installed inside the internal air duct 14. The purification component 4 can generate ions with air purification effects such as sterilization and deodorization, and the generated ions can be diffused within the internal air duct 14 or blown into the room, thereby improving the air purification effect.

[0118] In some embodiments, the purification component 4 is installed at the air outlet 12 (not shown in the figure) to blow the generated ions into the room and diffuse them.

[0119] In some embodiments, the purification component 4 is installed at the air inlet 11 (not shown in the figure) to facilitate the introduction of ions into the housing 1 of the indoor unit for purification of the interior of the indoor unit.

[0120] In some embodiments, the purification component 4 is disposed on one side of the air guide plate 13. The oscillation of the air guide plate 13 can expand the range that ions can reach.

[0121] In some embodiments, the purification component 4 is mounted on a bottom surface of the housing 11. This bottom surface forms the bottom of the indoor air duct.

[0122] Reference Figure 4 In some embodiments, the purification component 4 includes an anode component 41.

[0123] In some embodiments, the anode assembly 41 includes an anode carrier. The anode carrier is configured as a porous structure.

[0124] In some embodiments, the anode assembly 41 includes a photocatalyst. The photocatalyst is uniformly loaded on the anode carrier.

[0125] Under the action of the light source 43, the photocatalyst generates electrons and holes. Under the gradient electric field, electrons migrate to the cathode component 42 and undergo a reduction reaction with air, while holes remain on the surface of the photocatalyst, causing the holes to oxidize water and generate hydroxyl radicals to remove gaseous pollutants.

[0126] In the above, the photocatalyst can be set as ultraviolet or visible light responsive materials such as titanium oxide, cerium oxide, zinc oxide, perovskite, semiconductor quantum dots, graphene, hydroxyl oxide, and hydrotalcite.

[0127] The anode carrier can be configured as a porous structure such as honeycomb aluminum, honeycomb ceramic, porous sponge, or foam metal.

[0128] In some embodiments, the photocatalyst can be uniformly loaded onto the anode carrier by means of impregnation, fluorine coating, deposition, in-situ growth, etc.

[0129] In some embodiments, the purification component 4 includes a light source 43. The light source 43 is mounted above the anode component 41, which generates electrons and holes when illuminated.

[0130] In some embodiments, the light source 43 is disposed on an LED light panel. The light radiation area of ​​the LED light panel covers the entire area of ​​the anode assembly 41. In some embodiments, the LED light panel is configured to have an array of 1-50 ultraviolet lamp columns or visible light lamp beads.

[0131] Multiple light sources 43 are provided. The light sources 43 are positioned directly above the anode assembly 41. The emitted light vertically illuminates the surface and internal channels of the anode assembly 41.

[0132] The purification assembly 4 includes a cathode assembly 42. The cathode assembly 42 is disposed on one side of the anode assembly 41. The voltage of the cathode assembly 42 is lower than the voltage of the anode assembly 41.

[0133] In some embodiments, the cathode assembly 42 includes a cathode carrier. The cathode carrier is configured with a porous structure.

[0134] In some embodiments, the cathode assembly 42 includes a cathode catalyst. The cathode catalyst is uniformly loaded on a cathode support to catalyze the reduction reaction of electrons located on the cathode assembly 42.

[0135] In the above, the cathode catalyst can be set as transition metal oxides such as manganese oxide, cobalt oxide, iron oxide, and copper oxide, precious metal-based nanomaterials such as gold, silver, and platinum, and adsorption-type composite catalytic materials such as molecular sieves and activated carbon.

[0136] In some embodiments, the cathode support is configured as a porous structure such as honeycomb aluminum, honeycomb ceramic, porous sponge, or foamed metal. In some embodiments, the cathode catalyst can be uniformly loaded onto the support by means of impregnation, coating, deposition, in-situ growth, or other methods.

[0137] In some embodiments, the gap between the cathode assembly 42 and the anode assembly 41 is less than 10 mm.

[0138] In some embodiments, the cathode assembly 42 and the anode assembly 41 are connected in contact.

[0139] The purification assembly 4 includes a pointed electrode 44. The pointed electrode 44 is disposed inside the cathode assembly 42. (See reference...) Figure 4 The tip electrode 44 is disposed inside the channel of the cathode assembly 42. The tip electrode 44 can be configured as a metal needle tip or a carbon fiber bundle.

[0140] In some embodiments, the tip electrodes 44 are configured to be 1-50.

[0141] In some embodiments, the tip electrode 44 is disposed on the side of the cathode assembly 42 away from the anode assembly 41.

[0142] The purification component 4 includes a first electrode 45. The first electrode 45 is installed between the anode component 41 and the cathode component 42. The voltage of the first electrode 45 is higher than the voltage of the tip electrode 44, so that electrons on the first electrode 45 are continuously transferred to the tip electrode under the action of the electric field and released as negative ions on the cathode component 42 to undergo a reduction reaction with the air.

[0143] A gradually decreasing gradient electric field is formed between the anode assembly 41, the first electrode 45, the cathode assembly 42, and the tip electrode 44 to construct a transfer path for electrons from the anode assembly 41 and the cathode assembly 42, and to form a cathode reduction region at the cathode assembly 42.

[0144] In some embodiments, indoor air enters the internal air duct 14 through the air inlet 11 and undergoes an oxidation reaction with the cavities near the anode component 41. The purified indoor air then returns to the room through the air outlet 12.

[0145] In some embodiments, indoor air enters the internal air duct 14 through the air inlet 11 and undergoes a reduction reaction with electrons or negative ions near the cathode component 42. The purified indoor air then returns to the room through the air outlet 12.

[0146] In some embodiments, refer to Figure 15 A high-voltage power supply is connected between the tip electrode 44 and the first electrode 45, so that electrons on the first electrode 45 are continuously transferred to the tip electrode 44 under the action of the electric field, and are released in the cathode assembly 42 region in the form of negative ions, participating in the reduction reaction. This design can establish a gradient electric field from the cathode assembly 42 to the anode assembly 41 region, constructing an electron transfer path from the outside to the inside, maximizing the separation rate and utilization rate of electron-hole pairs.

[0147] In some embodiments, a high voltage of 1 kV-5 kV is connected between the tip electrode 44 and the first electrode 45.

[0148] In some embodiments, refer to Figure 5 The purification component 4 also includes a second electrode 46. The second electrode 46 is installed on the side of the anode component 41 away from the first electrode 45. The voltage of the second electrode 46 is higher than that of the first electrode 45, so as to establish an electric field inside the anode component 41, causing electrons in the anode component 41 to tend to move towards the first electrode 45 and holes to tend to move towards the second electrode 46.

[0149] In some embodiments, a high-voltage power supply is connected between the first electrode 45 and the second electrode 46 to establish an electric field inside the anode assembly 41, thereby enabling the effective separation and directional migration of electrons and holes generated by the anode assembly 41, wherein electrons tend to move toward the first electrode 45 and holes tend to move toward the second electrode 46.

[0150] In some embodiments, refer to Figure 15 A high voltage of 3kV-20kV is connected between the first electrode 45 and the second electrode 46. This design can establish a gradient electric field in the region from the cathode assembly 42 to the anode assembly 41, constructing a transmission path for electrons from the outside to the inside, and maximizing the separation rate and utilization rate of electron-hole pairs.

[0151] The operating principle of the purification component 4 in this application is as follows: After the anode component 41 is exposed to light, it generates electrons and holes. When the electrode is connected to a high-voltage power supply, the anode component 41 has a higher potential than the cathode component 42. Under the influence of the electric field, electrons migrate to the cathode component 42, continuously providing electrons to the tip electrode 44. Holes remain on the surface of the photocatalyst, which can oxidize water to generate hydroxyl radicals, used to remove gaseous pollutants, or directly oxidize gaseous pollutants into harmless molecules.

[0152] The pointed electrode 44 releases negative ions, and the high electron concentration around the cathode assembly 42 region makes it easy for reactants to gain electrons and be reduced. Since the cathode catalyst in the cathode assembly 42 is composed of oxygen-loving active materials, it can quickly generate superoxide radicals, which are used to remove gaseous pollutants and reduce ozone concentration.

[0153] In some embodiments, the gas within the channels of the anode assembly 41 and the cathode assembly 42 can be ionized under high voltage to generate low-temperature plasma, which is used to activate gaseous pollutant molecules and promote catalytic reactions.

[0154] In some embodiments, the light source 43 can be replaced. When the voltage applied between the first electrode 45 and the second electrode 46 is greater than the breakdown voltage of the gas, a glow discharge is generated, emitting ultraviolet light, which can be used to excite the anode assembly 41 in the first electrode 45 and the second electrode 46.

[0155] In some embodiments, the purification component 4 includes an anode component 41, a cathode component 42, a tip electrode 44, and a first electrode 45.

[0156] In some embodiments, the purification component 4 includes an anode component 41, a cathode component 42, a tip electrode 44, and a second electrode 46.

[0157] By setting a tip electrode 44 and a first electrode 45, or a tip electrode 44 and a second electrode 46, the driving electric field from the cathode assembly 42 to the anode assembly 41 can be satisfied. That is, electrons generated by the anode assembly 41 tend to move towards the cathode electrode and are transferred to the tip electrode 44 through the external circuit, and released in the form of negative ions. This also improves the separation degree of electrons and holes.

[0167] Reference Figure 7 The cathode assembly 42 is configured as a porous annular structure. The anode assembly 41 is configured as a porous disk-shaped structure, nested inside the cathode assembly 42. Annular electrodes are disposed on the outside of the anode assembly 41, and a ring array of pointed electrodes 44 is distributed throughout the cathode assembly 42. A high-voltage electric field is applied between the annular electrodes and the pointed electrodes 44, creating a pathway for electrons to travel from the inside out. Oxygen and ozone reduction reactions occur in the cathode assembly 42, while holes remain in the anode assembly 41 and undergo oxidation reactions of gaseous pollutants.

[0168] In some embodiments, the purification component 4 includes at least one anode component 41 and at least one cathode component 42. The anode component 41 and the cathode component 42 are installed alternately, and the voltage of the cathode component 42 is lower than that of the anode component 41, so that electrons move from the anode component 41 towards the cathode component 42, and holes move from the cathode component 42 towards the anode component 41.

[0169] In the above embodiment, the anode assembly 41 and the cathode assembly 42 are arranged alternately to form an array combination module. (Refer to...) Figure 8 The purification module includes a third electrode 47, a fourth electrode 48, and a fifth electrode 49. It should be noted that...

[0170] In some embodiments, the third electrode 47 is configured as an anode assembly 41, the fourth electrode 48 is configured as a cathode assembly 42, and the fifth electrode 49 is configured as an anode assembly 41. A high-voltage electric field is established between the fourth electrode 48 and both the third electrode 47 and the fifth electrode 49. The fourth electrode 48 is connected to a negative high voltage, while the third electrode 47 and the fifth electrode 49 are grounded or connected to a positive high voltage.

[0176] This application provides a purification component 4, including an anode component 41, a cathode component 42, a light source 43, and electrode elements. Positive and negative electric fields are established between the anode component 41 and the cathode component 42 using the electrode elements.

The anode component 41 and the cathode component 42 each perform their respective functions, generating a large number of active oxygen species to efficiently remove gaseous pollutants. The process does not cause the accumulation of excess electrons / holes, allowing the reaction to proceed continuously and efficiently.

[0177] Compared to traditional photocatalytic modules, this application improves quantum efficiency and light energy utilization by constructing a gradient electric field and a cathode reduction region, thereby enhancing the catalytic conversion performance of gaseous pollutants.

[0195] In some embodiments, the air conditioner 100 includes a purification device 5. The purification device 5 can be used to purify indoor air.

[0196] In some embodiments, the purification device 5 may be installed within the internal air duct 14. (See reference...) Figure 11 The airflow passes through the entire catalytic module 51.

[0197] In some embodiments, the purification device 5 may be installed at the air outlet 12.

[0198] In some embodiments, the purification device 5 may be installed at the air inlet 11.

[0199] In some embodiments, refer to Figure 11 The purification device 5 includes a catalytic module 51. The catalytic module 51 is used to decompose harmful gases into harmless or low-toxicity substances using a catalyst.

[0200] In some embodiments, the catalytic module 51 is configured as an adsorption catalytic module, a room temperature catalytic module, or a photocatalytic module.

[0201] In some embodiments, the catalytic module 51 is configured as the purification component 4 described above.

[0202] In some embodiments, the purification device 5 includes an electric field generating device 52. The electric field generating device 52 is installed on both sides of the catalytic module 51 so that the released electric field covers the entire catalytic module 51.

[0203] In some embodiments, the purification device 5 includes a dust collection module 53. The dust collection module 53 is installed below the catalyst module 51 so that dust on the catalyst module 51 falls onto the dust collection module 53.

[0204] In some embodiments, the controller 21 is configured to determine that cleaning is required when the interval between the current power-on and the last power-off exceeds a first preset time after power-on.

[0205] In some embodiments, when cleaning and purifying device 5 is in use, electric field generating device 52 is turned on, and electric field generating device 52 generates alternating current. The particles on the surface of catalytic module 51 oscillate back and forth in the electric field. The particles electrocoagulate and stick together to form polarized particle clusters, which then fall onto dust collection module 53.

[0206] This embodiment aims to address the problem that the surface of the catalytic module 51 in the purification device 5 is easily covered by particulate matter, resulting in poor long-term effectiveness. The presence of dust adhering to the surface of the catalytic module 51 is determined by acquiring the device's operating interval and the indoor particulate matter concentration, and the form of the input electric field is selected based on the determination result.

[0207] In cases where particulate matter adsorption may occur, the electric field generator 52 is turned on, causing the fine particulate matter to oscillate back and forth in the alternating electric field, moving it away from the surface of the catalyst module 51 and eventually collecting it in the dust collection assembly, thus maintaining the clean state of the surface of the catalyst module 51.

[0208] In some embodiments, after cleaning and purifying the module, after a period of time, the concentration of gaseous pollutants and particulate matter are obtained, the type of electric field generating device 52 is determined based on the particulate matter concentration, and the target electric field strength of the electric field generating device 52 is determined based on the change in the concentration of gaseous pollutants, so as to purify the air using the catalytic module 51.

[0209] In some embodiments, after cleaning the purification module, the concentration of gaseous pollutants and particulate matter are immediately obtained, the type of electric field generating device 52 is determined based on the particulate matter concentration, and the target electric field strength of the electric field generating device 52 is determined based on the change in the concentration of gaseous pollutants, so as to purify the air using the catalytic module 51.

[0210] In some embodiments, the target electric field strength of the electric field generating device 52 is determined based on the instantaneous purification efficiency of gaseous pollutants, wherein there is a linear relationship between the target electric field strength and the instantaneous purification efficiency.

[0211] The target electric field strength of the electric field generating device 52 is determined based on the instantaneous purification rate of gaseous pollutants, thereby promoting the catalytic reaction and enabling the catalytic module 51 to operate in a long-term and efficient manner.

[0212] In some embodiments, a mathematical model between the target electric field strength and the instantaneous purification efficiency is obtained by fitting a large amount of experimental data.

[0213] In some embodiments, the real-time purification efficiency of gaseous pollutants can be detected using appropriate sensors and monitoring equipment to obtain accurate purification efficiency values. The detected real-time purification efficiency is then input into a mathematical model to calculate the corresponding target electric field strength.

[0214] In the process of establishing a mathematical model, environmental conditions such as the type and concentration of pollutants, gas flow rate, temperature and humidity can be incorporated to calibrate the mathematical model of instantaneous purification efficiency and electric field strength.

[0215] In some embodiments, the controller 21 is configured to determine that the catalytic module 51 does not need to be cleaned when the interval between the current power-on and the last power-off does not exceed a first preset time after power-on, and to obtain the concentration of gaseous pollutants in the indoor air.

[0216] In some embodiments, when the concentration of gaseous pollutants exceeds a first preset concentration, the concentration at this time is recorded as the initial concentration C0, and the catalytic module 51 is run to decompose the harmful gas.

[0217] In some embodiments, the controller 21 is configured to record the current concentration of gaseous pollutants as Ct when the catalytic module 51 runs for a second preset time Δt, and obtain the instantaneous purification rate η of the gaseous pollutants.

[0218] In some embodiments, the instantaneous purification efficiency η of gaseous pollutants is:

[0219] n=(C0-Ct) / Δt

[0220] In some embodiments, the target electric field strength of the electric field generating device 52 is determined based on the instantaneous purification efficiency of the gaseous pollutants.

[0221] In some embodiments, the concentration of particulate matter in indoor air is obtained, and when the concentration of particulate matter exceeds a second preset concentration, the electric field generator 52 is controlled to input alternating current so that the electric field generator 52 generates an alternating electric field.

[0222] In some embodiments, the controller 21 is configured to control the electric field generator 52 to output direct current when the particulate matter concentration does not exceed a second preset concentration, so as to generate positive / negative potentials on the catalytic module 51 using a high-voltage electric field, thereby enhancing the catalytic oxidation and catalytic reduction performance of the catalytic module 51.

[0223] In some embodiments, during the process of the electric field generator 52 outputting DC power, when the time for outputting DC power exceeds a third preset time, the electric field generator 52 switches to input AC power for a period of time and generates an AC electric field, so as to realize the alternating operation of DC electric field and AC electric field.

[0224] In some embodiments, when the gaseous pollutant does not exceed the first preset concentration, it is determined whether the electric field generating device 52 is in the start state.

[0225] In some embodiments, if the electric field generator 52 is in the start-up state, the input power of the electric field generator 52 is adjusted to AC power, and then the electric field generator 52 and the catalytic module 51 are turned off in sequence.

[0226] In some embodiments, when the concentration of gaseous pollutants does not exceed a first preset concentration, and the electric field generating device 52 is not in the start state, the operation of the catalytic module 51 is stopped.

[0227] Reference Figure 12 This describes the self-cleaning and indoor air cleaning control logic of the purification device 5 in the embodiments of this application.

[0228] Get the time interval between the current power-on and the last power-off of the purification device 5 (S1201);

[0229] Determine whether the interval time exceeds the first preset time (S1202);

[0230] In step S1202, if the first preset time is exceeded, it is assumed that the surface of the catalytic module 51 is covered with a layer of dust, and step S1203 is executed to turn on the electric field generator 52 and connect AC power to generate an AC electric field.

[0231] After a period of time has elapsed since step S1203 was executed, step S1204 is executed.

[0232] In step S1202, if the first preset time has not been exceeded, it is considered that the surface of the catalytic module 51 does not need to be cleaned, and then step S1204 is executed to directly obtain the indoor gaseous pollutant concentration and particulate matter concentration.

[0233] The concentration of gaseous pollutants is determined to exceed the first preset concentration (S1205);

[0234] In step S1205, if the concentration exceeds the first preset concentration, then step S1206 is executed, the concentration of gaseous pollutants at this time is recorded as the initial concentration C0, and the catalytic module 51 is run.

[0235] In step S1205, if the first preset concentration is not exceeded, then step S1207 is executed to determine whether the electric field generating device 52 is in the start state.

[0236] In step S1207, if the device is in the start-up state, step S1208 is executed to adjust the input AC power of the electric field generator 52 to generate an AC electric field in order to avoid excessive charge accumulation on the surface of the catalytic module 51; then the electric field generator 52 and the catalytic module 51 are turned off in sequence (S1209).

[0237] If the system is not in the start-up state in step S1207, then step S1210 is executed to directly stop the operation of the catalytic module 51.

[0238] Reference Figure 13 This section explains the control logic of the electric field generating device 52 in the embodiments of this application.

[0239] When the concentration of gaseous pollutants exceeds the first preset concentration, the concentration at this time is recorded as the initial concentration C0, and the catalytic module 51 (S1301) is run.

[0240] When the operating time of the catalytic module 51 reaches the second preset time, the current concentration of gaseous pollutants Ct(S13O2) is recorded;

[0241] Obtain the instantaneous purification efficiency of gaseous pollutants (S1303);

[0242] The target electric field strength of the electric field generating device 52 is determined based on the immediate purification efficiency of gaseous pollutants (S1304).

[0243] Determine whether the indoor particulate matter concentration exceeds the second preset concentration (S1305);

[0244] In step S1305, if the concentration exceeds the second preset concentration, step S1306 is executed, and the electric field generating device 52 outputs an alternating electric field, causing indoor particulate matter to move away from the catalytic device and be adsorbed onto the dust collection component, thereby avoiding interference of particulate matter with the performance of the catalytic module 51 and ensuring that gaseous pollutants are completely removed from the catalytic module 51.

[0245] In S1305, if the concentration does not exceed the second preset concentration, the indoor particulate matter concentration is considered to be extremely low. Therefore, the influence of particulate matter on the catalytic module 51 can be ignored. Then, step S1307 is executed, in which a DC electric field is input, and an extreme positive / negative potential is generated on the catalytic module 51 using a high-voltage electric field. This enhances the catalytic oxidation and catalytic reduction reaction performance of the catalytic module 51 and improves the removal rate of gaseous pollutants.

[0246] If the continuous input time of the DC electric field is obtained (S1308), and it is determined whether the continuous input time exceeds the third preset time (S1309), then step S1310 is executed to switch the AC electric field of the input end time.

[0247] In the above steps, the alternating operation of DC electric field and AC electric field is used to extend the service life of catalytic module 51 in strong electric field.

[0248] In some embodiments, the air conditioner 100 includes a microbial detection device 54. The microbial detection device 54 is electrically connected to the controller 21. The microbial detection device 54 is used to detect the species and concentration of microorganisms and send the data to the controller 21.

[0249] In some embodiments, the microbial detection device 54 is disposed at the air inlet 11.

[0250] In some embodiments, the controller 21 is configured to stop the operation of the catalytic module 51, acquire the types and concentrations of microorganisms, and determine the target electric field intensity output by the electric field generator 52 based on the types of microorganisms.

[0251] In some embodiments, the controller 21 is configured to input an AC voltage or a pulse voltage into the electric field generator 52 when the microbial concentration exceeds a third preset concentration.

[0252] Reference Figure 14 This describes the control logic for microbial removal in the embodiments of this application.

[0253] Obtain the types and concentrations of indoor microorganisms (S1401);

[0254] The target electric field strength (S1402) of the input electric field is determined based on the type of microorganism.

[0255] Determine whether the concentration of microorganisms exceeds the third preset concentration (S1403);

[0256] In step S1403, if the concentration exceeds the third preset concentration, step S1404 is executed, and the electric field generating device 52 outputs an alternating electric field or a pulsed electric field. The high electric field of several kilovolts per centimeter generates a transmembrane voltage on the cell membrane, causing electroporation or electrodisintegration on the cell membrane. The cell membrane is destroyed, leading to the death of microorganisms.

[0257] This embodiment of the application can prevent the catalytic module 51 from having its reactive sites covered by particulate matter during operation. Simultaneously, the applied electric field can promote the catalytic removal reaction of gaseous pollutants, improving the efficiency and durability of air purification and saving users replacement costs. Furthermore, this purification device 5 can also eliminate microorganisms in the air, thus achieving integrated purification of particulate matter, gaseous pollutants, and microorganisms.
