[0035] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] At present, the commonly used household air conditioner duct units are installed inside the ceiling, making it difficult to clean the inside of the air conditioner duct unit. Especially when there is residual water in the water tray of the air conditioner duct unit, it is the most serious source of pollution inside the air conditioner compared to other parts such as cabinet units and split units. When the air conditioner is used for a long time, various microorganisms such as bacteria and molds will breed in the water remaining in the water tray and on the surface of the water tray, and even form jelly-shaped impurities that block the water pump used to drain the water from the water tray. When the water in the water tray cannot be discharged for a long time, when the air conditioner is started again, it will form a strange smell and blow out, polluting the indoor air and affecting the health of users.

[0037] In the related art, an air duct unit with a built-in sterilization function adds an antibacterial agent to the water receiving tray and is integrally formed, and the water receiving tray with the antibacterial agent added is installed inside the air duct unit. However, in the related art, the sterilization of microorganisms is limited to the water receiving tray itself. Once a large amount of dust and water accumulate in the water receiving tray, the microbial breeding area will separate from the surface of the water receiving tray and will grow in the dust layer or water. As a result, the antibacterial water receiving tray cannot solve the bacterial and mildew problems in the dust layer and water layer, and there are sterilization dead corners, and effective sterilization cannot be achieved. As a result, when the air conditioner is started again, there will still be odor blowing out, polluting the indoor air.

[0038] Based on this, the embodiment of the present application provides an air conditioner, in which a sterilization module is arranged between the evaporator and the fan to improve the sterilization coverage. Figure 1 As shown, the air conditioner 10 comprises:

[0039] A main housing 101, on which a return air port 102 and an air outlet 103 are provided, and the return air port 102 and the air outlet 103 are connected to form an air duct path 104;

[0040] A fan assembly 105 disposed in the air duct path 104;

[0041] A water storage assembly 106 is disposed in the main housing 101, and the water storage assembly 106 is located at the air outlet end of the fan assembly 105;

[0042] An evaporator 107 is disposed in the main housing 101, and the evaporator 107 is located above the water storage assembly 106;

[0043] A sterilization module 108 is disposed in the main housing 101 , and the sterilization module 108 is located between the fan assembly 105 and the evaporator 107 .

[0044] In the embodiments of the present application, the sterilization module refers to a device or component that can generate sterilization ions.

[0045] In the present application, refer to Figure 1 As shown, when the sterilization module 108 is started, the sterilization ions released by the sterilization module 108 can diffuse from the inside of the air conditioner main shell 101 to the outside of the air conditioner main shell 101, including diffusing along the air duct path 104 toward the air outlet 103, and diffusing along the air duct path 104 toward the return air outlet 102.

[0046] In the present application, refer to Figure 1 As shown, the sterilization module 108 is disposed above the water storage component 106 , and the water storage component 106 is located at the air outlet end of the fan component 105 .

[0047] The embodiment of the present application arranges a sterilization module between the fan assembly and the evaporator, which are prone to dust, mold, and fungus accumulation, so that the water storage assembly, fan assembly, evaporator and other components can be sterilized during sterilization. The location setting of the sterilization module improves the sterilization coverage range.

[0048] In some embodiments of this application, see Figure 2 As shown, there is a height difference between the first area 109 and the second area 110 of the water storage assembly 106 . The first area 109 has a water storage space 117 , and the sterilization module 108 is located directly above the first area 109 .

[0049] In the present application, refer to Figure 2 As shown, the height of the first area 109 of the water storage component 106 is less than the height of the second area 110. When water accumulates in the water storage component 106, due to the height difference, the accumulated water will flow from the second area 110 to the water holding space 117 of the first area 109. At this time, the remaining accumulated water is gathered in the water holding space 117. The sterilization module 108 is set directly above the first area 109, including being set directly above the water holding space 117, so that the accumulated water in the first area 109 can be fully sterilized during sterilization, thereby improving the sterilization efficiency.

[0050] In some embodiments of this application, see Figure 3 As shown, the fan assembly 105 includes a plurality of wind wheels, and the sterilization module 108 is located between at least one group of wind wheels among the plurality of wind wheels, and has the same spacing as that between two wind wheels in a group of wind wheels.

[0051] In the present application examples, see Figure 3 As shown, when the air conditioner is provided with a plurality of parallel wind wheels, one or more sterilization modules 108 can be arranged at the outer edge of any wind wheel or at the corresponding center position between two adjacent wind wheels. This not only reasonably utilizes the sufficient installation space between the plurality of parallel wind wheels and avoids conflicts between the installation of one or more sterilization modules 108 and the installation of other components, but also, during sterilization, the sterilization ions generated by the sterilization module can fully cover and sterilize the water storage component under the sterilization module. In addition, the sterilization module is located in the middle of the parallel wind wheels and in the air duct. During sterilization, the sterilization ions generated by the sterilization module can fully diffuse along the direction of the wind wheel and along the direction of the evaporator, thereby improving the coverage of sterilization.

[0052] In some embodiments of this application, see Figure 3As shown, the fan assembly 105 includes one or more wind wheels, and the distance between the sterilization module 108 and the outer edge of the one or more wind wheels is less than the preset distance. A certain distance is maintained between the sterilization module 108 and the outer edge of the one or more wind wheels, which not only reasonably utilizes the sufficient installation space on the outer edges of the multiple wind wheels, but also makes the position of the sterilization module 108 close to the outer edge of one or more wind wheels and close to the wind wheel body, so that during sterilization, the sterilization ions generated by the sterilization module can be quickly and fully diffused along the direction of the wind wheel and along the evaporator, thereby improving the sterilization coverage.

[0053] In the present application examples, see Figure 3 As shown, when the air conditioner is provided with a plurality of parallel wind wheels, one or more sterilization modules 108 can be arranged on the outer edge of any wind wheel, and the distance between the one or more sterilization modules 108 and the outer edge of the one or more wind wheels is less than the preset distance, which not only reasonably utilizes the sufficient installation space between the plurality of parallel wind wheels and avoids the conflict between the installation of one or more sterilization modules 108 and the installation of other components, but also, during sterilization, the sterilization ions generated by the sterilization module can fully cover and sterilize the water storage component under the sterilization module; in addition, the sterilization module is at the outer edge of the wind wheel and close to the wind wheel body, and during sterilization, the sterilization ions generated by the sterilization module can quickly diffuse along the direction of the wind wheel and along the direction of the evaporator to improve the coverage of sterilization.

[0054] In the present application examples, see Figure 3 As shown, when sterilization is performed, the sterilization ions released by the sterilization module 208 can diffuse from the inside of the air conditioner main shell 101 to the outside of the air conditioner main shell 101, including diffusing along the air duct path 104 toward the air outlet 103, and diffusing along the air duct path 104 toward the return air outlet 102.

[0055] In some embodiments of this application, see Figure 4 As shown, the sterilization module 108 includes:

[0056] Positive and negative electrodes 111, the positive and negative electrodes 111 are used to generate bactericidal ions;

[0057] The high-voltage package assembly 112 is connected to the positive and negative electrode components 111 and is used to provide high-voltage electrical energy to the positive and negative electrode components 111 .

[0058] It should be noted that, refer to Figure 4 and Figure 5Shown, high-voltage package assembly 112 provides negative high voltage to produce electric field between the corona electrode and the collector of positive and negative electrode parts 111, seed electrons obtain energy from electric field, collide with neutral particles and make it ionize to produce free electrons and positive ions, and produce negative ions by adsorption process, thereby produce sterilizing ion cluster (comprising positive ions, negative ions, neutral particles).Like this, utilizing the ionization and adsorption process of corona discharge, sterilizing ions can be produced.

[0059] In some embodiments of this application, see Figure 4 As shown, the sterilization module 108 also includes:

[0060] The diffusion cover 113 is provided with an opening 114 of the sterilization module 108 . When the sterilization module 108 is started, the sterilization ions are released from the opening 114 of the sterilization module.

[0061] In the present application, refer to Figure 1 and Figure 4 As shown, based on the corona discharge principle, negative ions capable of sterilization are generated between the electrodes of the positive and negative electrode members 111, and the negative ions are released through the openings 114 provided on the diffusion cover 113. The released sterilizing ions can diffuse into the air duct path 104 and / or the water flow path 118, and cover the surfaces of all parts of the air duct path 104 and / or the water flow path 118, as well as the accumulated water in the water storage assembly 106, so as to sterilize the air duct path 104 and / or the water flow path 118. The position setting of the sterilization module improves the sterilization coverage range.

[0062] In some embodiments of this application, see Figure 4 As shown, the high voltage package assembly 112 includes:

[0063] A power supply 115, the power supply 115 is used to provide electrical energy to the positive and negative electrode members 111;

[0064] The pulse storm module 116 is used to generate a high-voltage pulse electric field. The positive and negative electrodes 111 generate sterilizing ions under the action of the high-voltage pulse electric field.

[0065] In the present application, refer to Figure 4 and Figure 5As shown, the power supply 115 is used to provide negative high voltage, and the pulse storm module 116 is used to generate a high-voltage pulse electric field between the corona electrode and the collector of the positive and negative electrode members 111. The process of the pulse storm module 116 generating sterilizing ions based on the corona discharge principle includes: ionization process: seed electrons obtain energy from the electric field, collide with neutral particles to ionize them to generate free electrons and positive ions, and the newly generated electrons will ionize neutral molecules after obtaining enough energy to generate more electrons and positive ions to form an electron avalanche; adsorption process: the free electrons generated by ionization are adsorbed by negatively charged gases to form negative ions. The negatively charged gases in the air are mainly oxygen, so the electrons are mainly combined with oxygen molecules to form negative oxygen ions; compound process :The recombination process mainly occurs in the ionization zone, where positive ions recombine with electrons or negative ions to form neutral molecules. The rate constant of the recombination reaction is related to the electron energy. The higher the energy, the more difficult it is to recombine; Secondary electron emission process: Corona discharge is a self-sustaining discharge and does not require an external ionization source, so secondary electrons must occur. It is generally believed that the secondary electron emission of corona discharge is mainly caused by photoionization and positive ion bombardment of the cathode surface, and there is also the possibility of field-induced emission; Migration motion process: The directional motion of charged particles under the inter-electrode electric field; Diffusion motion process: The free diffusion process of charged particles; Spatial charge distribution: The movement of charged particles in the discharge area produces a changing spatial charge field, which affects the distribution of the entire inter-electrode electric field.

[0066] Exemplarily, the blowing distance of the ion wind directly blown by the pulse storm may be 0.5 to 1 m.

[0067] In some embodiments of the present application, refer to Figure 2 As shown, the first area 109 and the second area 110 of the water storage assembly 106 have a height difference, the first area 109 has a water storage space 117 , and the first area 109 is within the coverage area of ​​the bactericidal ions released by the diffusion cover 113 .

[0068] The water storage component may be a water receiving tray of an air conditioner, and the water storage space 117 may also be referred to as a water accumulation area of ​​the water receiving tray.

[0069] In the present application, refer to Figure 2 As shown, the sterilization module 108 is arranged directly above the water holding space 117 of the water storage component 106, and an opening 114 is arranged on the diffusion cover 113 of the sterilization module 108. The direction of the opening 114 is toward the water holding space 117 of the water storage component 106, so that when the sterilization module 108 is started to release sterilization ions, it can ensure that the water holding space 117 can be completely covered by the sterilization ions released by the diffusion cover 113, thereby improving the sterilization effectiveness.

[0070] In some embodiments of this application, see Figure 1 As shown, the air conditioner 10 also includes:

[0071] The return air port 102 and the air outlet 103 on the main housing 101 are connected to form an air duct path 104;

[0072] The water storage assembly 106 can receive the condensed water on the evaporator 107 and store the condensed water. The path of the condensed water from the evaporator 107 to the water storage assembly 106 forms a water flow path 118;

[0073] The sterilization module 108 is used to sterilize the air duct path 104 and the water flow path 118 .

[0074] In the present application, refer to Figure 1 As shown, the sterilization module 108 is disposed above the water storage assembly 106 , and is located in a vacant position between components of the water flow path 118 and components of the air duct path 104 .

[0075] It should be understood that reference Figure 1 As shown, the sterilization module 108 is arranged at the intersection of the air duct path 104 and the water flow path 118. On this basis, the sterilization module 108 is arranged directly above the water storage space 117 of the water storage component 106 and is located at a reasonable position between the evaporator 107 and the fan component 105.

[0076] In the present application, refer to Figure 1 As shown, the air conditioner is also provided with a fan assembly 105, which is used to introduce outdoor air from the return air port 102 into the air duct path 104 and then discharge it into the room from the air outlet 103. When the sterilization module 108 is turned on, the fan assembly accelerates the air circulation speed in the air duct path 104, so that the sterilization ions generated by the sterilization module 108 can quickly diffuse through the air duct path 104 to the inside of the air duct machine of the air conditioner, thereby achieving effective sterilization of various equipment in the air duct path 104 and the water flow path 118.

[0077] In some embodiments of the present application, refer to Figure 2 As shown, the air conditioner 10 also includes:

[0078] The water pump 119 is used to drain the water storage assembly 106 .

[0079] In the present application, refer to Figure 1 As shown, the water pump 119 is used to drain the water in the water storage space 117 of the water storage assembly 106 to effectively reduce the water accumulation inside the air conditioner.

[0080] In the embodiment of the present application, a sterilization module is arranged between the evaporator and the fan, and during sterilization, the water storage component, the fan component, the evaporator and other components can be sterilized, and the location of the sterilization module improves the coverage of sterilization. In this way, by arranging the sterilization module at the intersection center of the wind circuit (corresponding to the aforementioned wind duct path) and the water circuit (corresponding to the aforementioned water flow path) that are prone to dust accumulation, mold and fungus growth inside the air duct machine of the air conditioner, the location advantage of the sterilization module is maximized. The sterilization module generates a sterilizing ion group based on the principle of corona discharge. The ion wind of the pulse storm formed by the sterilizing ion group blows directly to the water receiving area below the evaporator component of the water circuit, and can quickly spread to the surface of all objects in the wind circuit (corresponding to the surface of the aforementioned components), thereby improving the coverage of sterilization.
