Description

Technical Field

[0001] The present invention relates to the technical field related to air conditioners, and in particular to an air conditioner and a control method for the air conditioner. Background Art

[0002] With the improvement of health awareness, people have increasingly stringent requirements for indoor air quality, especially in public spaces and home environments. As an important device for regulating indoor temperature and humidity, the sterilization ability of the air conditioning system is directly related to the health and safety of users. However, the existing air conditioning sterilization technology has encountered a series of problems in practical applications. Not only is the sterilization effect limited, but there may also be a risk of secondary pollution, such as:

[0003] HEPA filter technology: HEPA filters can effectively filter tiny particles in the air, including some bacteria and viruses, but their sterilization effect is not thorough. More importantly, HEPA filters will accumulate a lot of pollutants after being used for a period of time. If they are not replaced in time, these pollutants may be released back into the air, causing secondary pollution.

[0004] UVC ultraviolet sterilization: UVC can destroy the DNA structure of microorganisms and achieve sterilization. However, UVC technology requires high cost investment, including maintenance and replacement of light sources, and its sterilization effect is limited by the intensity of the light source and the exposure time. In some cases, UVC may also produce ozone, posing a potential threat to human health.

[0005] Self-cleaning technology: The self-cleaning technology used in some air conditioners, such as 56° high-temperature cleaning, can only kill bacteria to a certain extent, but it cannot be used in cooling mode, and the cleaning effect is limited and cannot completely remove all microorganisms and pollutants.

[0006] Most existing sterilization technologies rely on physical filtration or chemical effects. In actual operation, pollutants accumulated on filters, evaporators and other components may be blown back into the room when the air conditioner is started again. Especially on the surface of HEPA filters, bacteria and viruses that are not completely captured may become new sources of pollution. This not only reduces the sterilization efficiency, but also increases the risk of secondary pollution, affecting the indoor air quality.

[0061] Embodiment 1

[0062] In order to solve the problems of low sterilization efficiency and easy secondary pollution in the air conditioner in the prior art, the present invention provides an air conditioner for adjusting indoor temperature.

[0063] like Figures 1 to 5 As shown, the air conditioner includes a casing 10, an evaporator 60, a multi-ion sterilization module 50 and a humidifier 40. The casing 10 has an air duct 120 and an air outlet 110 connected to the air duct 120. At least a portion of the evaporator 60 is arranged inside the air duct 120. The multi-ion sterilization module 50 is arranged inside the air duct 120. At least one multi-ion sterilization module 50 is arranged on the air inlet side of the evaporator 60. At least another multi-ion sterilization module 50 is arranged between the evaporator 60 and the air outlet 110. The humidifier 40 is arranged on the casing 10. The mist outlet 431 of the humidifier 40 is connected to the air duct 120 and is arranged on the air inlet side of the evaporator 60. At least a portion of the mist outlet 431 is arranged toward the multi-ion sterilization module 50.

[0064] Specifically, the air conditioner of the present application adopts a multi-ion sterilization module 50 and a humidifier 40 to be arranged inside the air duct 120, and the mist outlet 431 of one of the multi-ion sterilization modules 50 and the humidifier 40 is arranged at the front end of the evaporator 60, which can effectively improve the cleanliness and sterilization effect of the air. At the same time, the setting of the humidifier 40 can improve the dry environment indoors and enhance the user's comfort. On the other hand, in the control method, the execution of the self-cleaning mode and the sterilization mode is adjusted according to the actual downtime and real-time humidity, so that the air conditioner can intelligently select the best operation mode according to environmental changes, further improve the air quality and equipment operation efficiency, and bring users a healthier and more comfortable use experience.

[0065] Among them, the air duct 120 is used for gas flow. During the flow process, the gas will pass through the fins of the evaporator 60 located inside the air duct 120, that is, the water mist discharged from the mist outlet 431 and the various ions generated by the multi-ion sterilization module 50 including water ions, positive ions, negative ions and plasma will flow through the fins with the gas. The various ions generated by the multi-ion sterilization module 50 can sterilize the body, and the killed bacteria and dust can be fixed by freezing on the surface of the fins when flowing through the fins.

[0066] In this embodiment, the multi-ion sterilization module 50 is arranged at the front end of the evaporator 60. When the negative ions flow through the evaporator 60 with the gas, the evaporator 60 provides temperature, which is conducive to stimulating the activity of the negative ions, thereby improving the sterilization efficiency. In this application, the mist outlet 431 of the humidifier 40 is arranged at the front end of the evaporator 60. The humidifier 40 not only has the effect of assisting in providing water ions, but also can provide a humid environment to facilitate frosting and freezing of bacteria and dust at the fins of the evaporator 60, and facilitates the collection of dirt by melting, thereby improving the cleanliness of the air conditioner and the freshness of the ambient gas.

[0067] like Figures 1 to 5 As shown, the multi-ion sterilization module 50 located on the air inlet side of the evaporator 60 is arranged below the mist outlet 431 to facilitate the water mist discharged from the mist outlet 431 to contact with the multi-ion sterilization module. The water mist increases the humidity while also increasing the efficiency of water ion generation.

[0068] In this embodiment, the mist outlet 431 is disposed at the lower side of the air outlet 110 along the height direction of the housing 10 .

[0069] Specifically, the height direction of the housing 10 is Figure 1 The Z direction is shown.

[0070] In this embodiment, the multi-ion sterilization module 50 disposed between the evaporator 60 and the air outlet 110 is disposed on the housing 10 and close to the air outlet 110 to achieve sterilization treatment of the gas flowing toward the air outlet 110 .

[0071] Specifically, the air conditioner further includes a protective net structure 20, which is arranged at the air outlet 110, and the multi-ion sterilization module 50 is arranged on the side of the protective net structure 20 facing the inside of the air duct 120. The protective net structure 20 is arranged at the air outlet 110 to protect the air outlet 110, and the multi-ion sterilization module 50 is arranged on the inner side of the protective net structure 20, which is conducive to preventing the multi-ion sterilization module 50 from being exposed, so as to improve the stability of the use of the multi-ion sterilization module 50.

[0072] like Figure 3 As shown, the casing 10 has a drainage groove 130 inside. The drainage groove 130 is arranged at the lower side of the evaporator 60 . The drainage groove 130 is used to collect liquid flowing down from the fins of the evaporator 60 .

[0073] Specifically, when the air conditioner is in the self-cleaning mode, frost on the fins freezes bacteria and dust, and the frost is melted to allow the waste liquid to flow into the drain groove 130 for centralized drainage.

[0074] In this embodiment, a water receiving tank may be provided to form the water receiving tank, or a groove may be formed on the inner wall surface of the housing 10 .

[0075] like Figure 3 As shown, the air conditioner further includes a humidity sensor 70 disposed inside the housing 10. The humidity sensor 70 is disposed on one side of the air inlet end of the evaporator 60 to detect the humidity of the gas flowing to the fins. When the humidity is high enough, frost can be formed on the fins of the evaporator 60.

[0076] In this embodiment, the multi-ion sterilization component emits ions into the interior of the air duct 120, and the multi-ion sterilization component includes a mounting frame 510, a water ion generating structure, a positive ion generating structure, and a negative ion generating structure, which are used to provide water ions, positive ions, and negative ions, respectively.

[0077] like Figures 1 to 5 As shown, the mounting frame 510 is fixed on the housing 10, the water ion generating structure is arranged on the mounting frame 510, and the mist outlet 431 is arranged toward the water ion absorbing rod 530 of the water ion generating structure, which is used to generate water ions; the plasma generating structure is arranged on the mounting frame 510, which is used to generate plasma; the positive and negative ion generating structure is arranged on the mounting frame 510, which is used to generate positive ions and negative ions. The water ions, plasma, positive ions, negative ions, and mist flow with the gas inside the air duct 120 toward the air outlet 110.

[0078] The multi-ion sterilization module 50 of the present application can simultaneously generate water ions, plasma, positive ions, and negative ions to achieve sterilization and fresh gas, which is beneficial to improving the user experience.

[0079] Specifically, the positive and negative ion generating structure includes a positive ion brush 550 and a negative ion brush 540 which are arranged in a one-to-one correspondence. The positive ion brush 550 and the negative ion brush 540 are arranged at both ends of the length direction of the mounting frame 510. The negative ion brush 540 is arranged on the inner side of the positive ion brush 550, and the water ion water absorption rod 530 and the plasma needle tip 520 of the plasma generating structure are arranged in the area between the negative ion brushes 540.

[0080] The mist outlet 431 is arranged to spray toward the water ion absorbing rod 530, thereby providing auxiliary function for the water ion generating structure to generate water ions through the water mist.

[0081] In this embodiment, the water ion water absorption rods 530 are symmetrically arranged on both sides of the plasma needle tip 520, and the symmetrically arranged water ion water absorption rods 530 are beneficial to increasing the water absorption efficiency; the negative ion brushes 540 are symmetrically arranged on both sides of the plasma needle tip 520, and the positive ion brushes 550 are symmetrically arranged on both sides of the plasma needle tip 520 to achieve the corresponding arrangement of the positive ion brushes 550 and the negative ion brushes 540.

[0082] like Figure 1 and Figure 2 As shown, the air conditioner further includes a water tank 30 disposed on the casing 10 , and the water tank 30 provides a water source for the humidifier 40 .

[0083] Specifically, the humidifier 40 includes an atomizer generator 410, a duct 420 and a mist exhaust structure 430. The atomizer generator 410 is arranged on the housing 10, the atomizer generator 410 is connected to the water tank 30, one end of the duct 420 is connected to the atomizer generator 410, the mist exhaust structure 430 is arranged inside the air duct 120 and is connected to the evaporator 60, the other end of the duct 420 is connected to the mist exhaust structure 430, and the mist outlet 431 is arranged on the mist exhaust structure 430.

[0084] The water in the water tank 30 is atomized by the atomizer 410 and then flows to the mist exhaust structure 430 through the conduit 420 , and is discharged to the inside of the air duct 120 through the mist outlet 431 on the mist exhaust structure 430 .

[0085] In this embodiment, the demisting structure 430 is connected and fixed to the evaporator 60, wherein the fixed connection structure may be a card slot 432 on the demisting structure 430, and the card slot 432 is card-connected and fixed to the evaporator 60, which is easy to operate and is beneficial to improving assembly efficiency; or the demisting structure 430 and the evaporator 60 are connected by fasteners, such as bolts, and the fixed connection between the demisting structure 430 and the evaporator 60 is achieved by the fasteners, which is beneficial to improving the connection strength between the demisting structure 430 and the evaporator 60.

[0086] like Figure 3As shown, the air conditioner also includes a driving member and a cross-flow blade 80. The driving member is arranged on the casing 10, and the driving member is connected to the cross-flow blade 80. The cross-flow blade 80 is rotatably arranged inside the air duct 120. The cross-flow blade 80 is arranged between the air outlet 110 and the evaporator 60, and one of the multi-ion sterilization modules 50 is arranged between the cross-flow blade 80 and the air outlet 110.

[0087] Specifically, the cross-flow fan blades 80 provide guidance and power for the internal gas flow of the air duct 120. The two multi-ion sterilization modules 50 are respectively arranged upstream and downstream of the cross-flow fan blades 80. The cross-flow fan blades 80 have the effects of drainage and pushing flow, which is beneficial to improving the smoothness of gas circulation and the stability of the sterilization module movement.

[0088] The driving component may be a structural component of a motor or a cylinder.

[0089] Embodiment 2

[0090] This embodiment provides a control method for an air conditioner, which is applied to the air conditioner in the first embodiment. The air conditioner has a self-cleaning mode and a sterilization mode. Figure 6 As shown, the control method of the air conditioner includes:

[0091] Get the power-on command, and the air conditioner starts running;

[0092] Determine the actual downtime of the multi-ion sterilization module 50 and compare it with the preset downtime;

[0093] Obtaining the real-time humidity inside the housing 10, and comparing the real-time humidity with the preset humidity;

[0094] According to the comparison structure of the actual downtime and the real-time humidity, it is determined whether to execute the self-cleaning mode and / or the sterilization mode.

[0095] Among them, the sterilization mode and the self-cleaning mode are performed asynchronously, the sterilization mode is performed first, and then the self-cleaning mode is performed.

[0096] In this embodiment, the actual shutdown time is the time between the current startup of the air conditioner and the last shutdown of the multi-ion sterilization module 50 ; the preset humidity is the humidity at which frost can form on the fins of the evaporator 60 .

[0097] In one specific implementation of this embodiment, when the actual downtime is greater than or equal to the preset downtime and the real-time humidity is less than the preset humidity, the sterilization mode is executed, and the sterilization mode includes:

[0098] The humidifier 40 is started, and the humidifier 40 operates until the real-time humidity is not less than the preset humidity;

[0099] The multi-ion sterilization module 50 is started, and the multi-ion sterilization module 50 runs for a first preset time;

[0100] Execute self-cleaning mode.

[0101] Among them, the first preset time and the preset downtime duration can be adaptively adjusted according to needs.

[0102] In this embodiment, since the multi-ion sterilization module 50 has not been turned on for a long time, the humidifier 40 and the multi-ion sterilization module 50 are both started, and the humidifier 40 stops working after adjusting the real-time humidity to the preset humidity. The humidity at this time can frost on the fins in the self-cleaning mode.

[0103] In another specific implementation of this embodiment, when the actual downtime is greater than or equal to the preset downtime, and the real-time humidity is greater than or equal to the preset humidity,

[0104] Execute the sterilization mode, which includes:

[0105] The multi-ion sterilization module 50 is started, and the multi-ion sterilization module 50 runs for a first preset time;

[0106] Execute self-cleaning mode.

[0107] In this embodiment, since the multi-ion sterilization module 50 has not been turned on for a long time, it is necessary to start the multi-ion sterilization module 50 to sterilize for a first preset time. Since the humidity at this time is sufficient for the self-cleaning mode, there is no need to start the humidifier 40.

[0108] In another specific implementation of this embodiment, when the actual downtime is less than the preset downtime, and the real-time humidity is less than the preset humidity,

[0109] Execute the sterilization mode, which includes:

[0110] The humidifier 40 is started, and the humidifier 40 operates until the real-time humidity is not less than the preset humidity;

[0111] The multi-ion sterilization module 50 is started, and the multi-ion sterilization module 50 stops after running for a first preset time, and then starts and runs for a first preset time after stopping for a second preset time, and stops when the total running time of the multi-ion sterilization module 50 is equal to a third preset time;

[0112] Execute self-cleaning mode.

[0113] In this embodiment, the multi-ion sterilization module 50 is not turned on for a short time, so it is not necessary to execute the self-cleaning mode after the multi-ion sterilization module 50 finishes running. The self-cleaning mode can be executed when the total running time of the multi-ion sterilization module 50 reaches the preset third time.

[0114] In another specific implementation of this embodiment, when the actual downtime is less than the preset downtime, and the real-time humidity is greater than or equal to the preset humidity,

[0115] Execute the sterilization mode, which includes:

[0116] The multi-ion sterilization module 50 is started, and the multi-ion sterilization module 50 stops after running for a first preset time, and then starts and runs for a first preset time after stopping for a second preset time, and stops when the total running time of the multi-ion sterilization module 50 is equal to a third preset time;

[0117] Execute self-cleaning mode.

[0118] In this embodiment, the self-cleaning mode includes:

[0119] Execute frost on the fins of the evaporator 60 condenser;

[0120] Perform frosting melting on fins;

[0121] The process stops after the preset number of cycles, which can be 1, 2, 3, 4, 5, 6, 7, 8, etc.

[0122] Specifically, the self-cleaning mode requires frosting, so the humidity in the environment needs to reach a preset humidity before frosting can be performed when cleaning is required. After the self-cleaning mode is activated, the fins of the evaporator 60 will condense and frost to fix the bacteria and dust. After the frost melts, the bacteria and dust flow to the sump along with the liquid.

[0123] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:
