Referring to fig. 1 to 5, an air-conditioning indoor unit 100 according to an embodiment of the present invention is described, where the air-conditioning indoor unit 100 is to be understood in a broad sense, that is, the air-conditioning indoor unit 100 may be a wall-hanging type air-conditioning indoor unit, a cabinet type air-conditioning indoor unit, etc., and the embodiment of the present invention is described with reference to a wall-hanging type air-conditioning indoor unit.

Referring to fig. 1 and 2, the indoor unit 100 of air conditioner of the embodiment of the present invention includes a body, the body has a casing 110, an evaporator 120, a wind wheel 130 and a plasma device are disposed in the casing 110, an air outlet 111 is disposed on the casing 110, wherein the wind wheel 130 is a cross flow wind wheel, the evaporator 120 surrounds the outside of the wind wheel 130, one side of the evaporator 120 close to the air outlet 111 is an open port, and the wind wheel 130 corresponds to the air outlet 111.

Referring to fig. 1, an air duct 112 is disposed inside the casing 110 between the evaporator 120 and the air outlet 111, the air duct 112 extends from the evaporator 120 to the air outlet 111, the plasma device is mounted on the air duct 112, the plasma device can be understood as a plasma generator, the plasma generator obtains plasma by using a discharge principle, the electrode 200 at least includes two conductive electrodes, in the embodiment, a connecting line between the electrodes 200 is disposed parallel to the air outlet 111, a connecting line between the two electrodes 200 is understood as a connecting line perpendicular to the two electrodes 200, and a connecting line between the electrodes 200 and the air outlet 111 are parallel to each other, which can be understood as a connecting line between the electrodes 200 and a plane of the air outlet 111 along a length direction. In operation, the electrode 200 is energized to generate a discharge phenomenon to form a plasma. Fig. 1 only shows the structure of the electrode 200, and the drawing does not show the specific structure of the plasma device, and the specific structure and principle of the plasma device are available to those skilled in the art and will not be described herein again.

Referring to fig. 1, the electrode 200 is disposed toward the inner side of the machine body, i.e., the electrode 200 is disposed toward the inside of the indoor unit 100. It can be understood that the plasma device generates plasma by discharging the electrode 200, and the plasma contains positive ions, negative ions and active substances, wherein the active substances include atomic oxygen, excited oxygen, hydroxyl radical OH, ozone O₃And the plasma is in an ionic state, namely, the plasma has positive ions and negative ions, the positive ions and the negative ions form ion wind due to flowing, under the action of the ion wind, the positive ions, the negative ions and active substances can be diffused towards the wind wheel 130 and the evaporator 120, so that bacteria attached to the surfaces of the wind wheel 130, the evaporator 120, the air duct 112 and other components can be killed by the plasma, and the connecting line of the electrode 200 is parallel to the air outlet 111, so that the positive ions or the negative ions cannot pass through adjacent electrodes when the plasma is transmitted to the inside of the air conditioner body, the neutralization quantity of the positive ions and the negative ions can be effectively reduced, the diffusion distance of the positive ions and the negative ions is further, the bacteria in the air conditioner indoor unit 100 can be effectively killed, the sterilization efficiency is improved, and the bacteria breeding is effectively avoided. Meanwhile, the electrode 200 faces the inside, so that the plasma is reduced from flowing away from the air outlet 111 to the outside of the indoor unit 100 of the air conditioner, the utilization rate of the plasma is improved, the sterilization efficiency is improved, and the sterilization effect is good.

It is easy to understand that the principle of plasma sterilization is that positive ions and negative ions are accumulated on the surface of bacteria, which causes electroporation of the bacterial membrane and cytoplasm overflow; moreover, the positive ions and the negative ions can generate energy to kill bacteria when being neutralized on the surfaces of the bacteria; meanwhile, the active substance has strong oxidizing property, and can oxidize cell membranes when contacting with bacteria, so that the cell membranes are inactivated, and the aim of sterilization is fulfilled. Therefore, the plasma is used for sterilizing the interior of the air-conditioning indoor unit 100, so that the bacteria breeding can be effectively inhibited, the air supply quality of the air-conditioning indoor unit 100 can be improved, and the health guarantee can be provided for users.

Referring to fig. 1, in some embodiments, the plasma device generates plasma by using corona discharge, specifically, the plasma generates discharge by using a tip discharge principle, the tip discharge belongs to one type of corona discharge, in embodiments, an electrode 200 of the plasma device includes a positive electrode 210 and a negative electrode 220, both the positive electrode 210 and the negative electrode 220 are tip electrodes and are arranged toward the wind wheel 130, tips of the positive electrode 210 and the negative electrode 220 are tips, the positive electrode 210 is connected to a positive electrode of a high voltage power supply, the negative electrode 220 is connected to a negative electrode of the high voltage power supply, and the positive electrode 210 and the negative electrode 220 are separated by a certain distance.

According to the principle of point discharge, under the action of a strong electric field, the points of the positive electrode 210 and the negative electrode 220 have a dense equipotential surface, and the electric field intensity increases sharply, so that the air near the points is ionized to generate gas discharge. It can be understood that the tip effect is more pronounced the sharper the tip of the electrode, since the sharper the tip, the greater the curvature, the higher the surface charge density, and the stronger the field strength in the vicinity thereof, under the same charge amount of the electrode 200 and its surrounding environment.

When the air conditioner indoor unit 100 works, enough direct current high voltage is applied to the positive electrode 210 and the negative electrode 220, positive and negative charges in air molecules between the positive electrode 210 and the negative electrode are subjected to strong electric field forces in opposite directions to generate air ionization, positive ions are formed at the tip of the positive electrode 210 after the air ionization, negative ions are formed at the tip of the negative electrode 220 to generate plasma, and because the tips of the positive electrode 210 and the negative electrode 220 face the direction of the wind wheel 130, ions generated by the discharge of the positive electrode and the negative electrode move towards the direction far away from the tip to form ion wind, the positive ions, the negative ions and active substances can be diffused towards the direction of the wind wheel 130 under the action of the ion wind, so that the plasma can be fully diffused to the positions of the wind wheel 130, the evaporator 120 and the like, the interior of the air conditioner indoor.

In the embodiment, the adopted high-voltage power supply is a direct-current power supply, the working voltage range is 3kV to 10kV, and the voltage requirement of the positive electrode 210 and the negative electrode 220 for point discharge can be met.

Referring to fig. 1, in some embodiments, the positive electrode 210 and the negative electrode 220 are disposed in parallel along the length direction of the air duct 112, and a connection line between the positive electrode 210 and the negative electrode 220 is parallel to the air outlet 111, which can be understood that a distance between the positive electrode 210 and the air outlet 111 is equal to a distance between the negative electrode 220 and the air outlet 111, so that positive ions and negative ions generated by the positive electrode 210 and the negative electrode 220 during point discharge can propagate toward the same direction, and during propagation, the positive ions do not pass through the negative electrode 220, and meanwhile, the negative ions do not pass through the positive electrode 210, so that the neutralization number of the positive ions and the negative ions can be effectively reduced, the propagation distance of plasma is further increased, and the sterilization of the inside of the air conditioning.

Referring to fig. 2 to 5, in some embodiments, the plasma device generates plasma by using a dielectric barrier discharge (dbd) method, and it can be understood from the principle of dbd discharge that dbd discharge is a non-equilibrium gas discharge in which an insulating dielectric is inserted into a discharge space.

Referring to fig. 2 and 3, in the embodiment, the electrode 200 includes a first electrode body 230 and a second electrode body 240, a discharge space is formed between the first electrode body 230 and the second electrode body 240, a first insulator 260 is inserted into the discharge space, the first electrode body 230 and the second electrode body 240 are both metal meshes, the first electrode body 230 is located above the first insulator 260, the second electrode body 240 is located below the second electrode body 240, and the coverage area of the first electrode body 230 and the second electrode body 240 is smaller than that of the first insulator 260, which is understood as the coverage area refers to the area of the opposite surfaces of the electrode bodies and the first insulator 260.

As shown in fig. 3, the coverage area of the first electrode body 230 is the lower surface area, the coverage area of the second electrode body 240 is the upper surface area, and the coverage area of the first insulator 260 is large enough to completely block between the two electrode bodies, so that the two electrode bodies cannot be directly opposite to each other, thereby satisfying the requirement of dielectric barrier discharge. The area of the lower surface of the first electrode body 230 and the area of the upper surface of the second electrode body 240 may be the same or different, and it is specifically required to satisfy that the coverage area of at least one electrode body is smaller than the coverage area of the first insulator 260, for example, the coverage area of the first electrode body 230 may be larger than the coverage area of the first insulator 260, and the coverage area of the second electrode body 240 may be smaller than the coverage area of the first insulator 260.

As shown in fig. 2, the first electrode body 230 and the second electrode body 240 are made of metal mesh structures, so that a large discharge area can be divided into a plurality of smaller discharge areas, which is beneficial to forming stable discharge, and meanwhile, the generated plasma can be spread through the metal mesh, so that the plasma is spread more uniformly and more efficiently.

The first electrode body 230 and the second electrode body 240 are respectively connected to a high voltage power supply, and the high voltage power supply can be a high voltage ac power supply or a high voltage pulse power supply, for example, the first electrode body 230 is connected to a high voltage end of the high voltage ac power supply, and the second electrode body 240 is connected to a low voltage end or grounded. When a sufficiently high alternating voltage is applied between the two electrode bodies, the gas between the two electrode bodies is broken down to generate dielectric barrier discharge, plasma is generated between the two electrode bodies, and the plasma flows out from the gap between the two electrode bodies. The working voltage range of the high-voltage power supply is 3kV to 10 kV.

Referring to fig. 2, in the embodiment, the first electrode body 230 and the second electrode body 240 are disposed in parallel, and a connecting line between the first electrode body 230 and the second electrode body 240 is parallel to the air outlet 111. As shown in fig. 2, the connecting line between the first electrode body 230 and the second electrode body 240 is along the vertical direction, and the plane of the air outlet 111 is along the vertical direction, it can be understood that the connecting line of the two electrode bodies is parallel to the plane of the air outlet 111. Because the first electrode body 230 and the second electrode body 240 are both metal meshes, generated plasma can flow out from the surfaces of the two electrode bodies to form ion wind and can be diffused towards the wind wheel 130, so that the inside of the air-conditioning indoor unit 100 can be effectively sterilized, and during the diffusion, the neutralization quantity of positive ions and negative ions can be effectively reduced, so that the propagation distance of the plasma is longer, and the sterilization of the inside of the air-conditioning indoor unit 100 is more effective.

Of course, the orientations of the first electrode body 230 and the second electrode body 240 can be adjusted according to actual requirements, for example, the upper surface of the first electrode body 230 can face the direction of the wind wheel 130, and the lower surface of the second electrode body 240 can face the direction of the wind tunnel 112.

It should be noted that the first electrode body 230 and the second electrode body 240 are not limited to the metal meshes shown in the above embodiments, and may be plate bodies, or one of the electrode bodies may be a metal mesh, and the other electrode body may be a plate body, and both the metal mesh and the plate body may be a plane, an arc surface, or a cylindrical structure. The first insulator 260 may be made of quartz, ceramic or teflon, and has better insulating property, uniform material, and is favorable for stable discharge.

Referring to fig. 4, in an embodiment, the difference from the embodiment shown in fig. 3 is that the insulating medium includes a first insulator 260 and a second insulator 270, wherein the first insulator 260 is interposed between the first electrode body 230 and the second electrode body 240, the second insulator 270 is located at the other side of the second electrode body 240, that is, the second electrode body 240 is located between the first insulator 260 and the second insulator 270, and the coverage areas of the first electrode body 230 and the second electrode body 240 are both smaller than the coverage areas of the first insulator 260 and the second insulator 270.

Because high voltage is applied between the first electrode body 230 and the second electrode body 240 in the working process, during assembly, the lower surface of the second insulator 270 can be fixedly installed toward the air duct 112, and the upper surface of the first electrode body 230 faces the wind wheel 130, so that the second insulator 270 can insulate the electrodes from the air duct 112, and the safety and the stability are effectively improved.

Referring to fig. 5, in an embodiment, the electrode 200 includes a first electrode body 230, a second electrode body 240, and a third electrode body 250, and the insulating medium includes a first insulator 260 and a second insulator 270, wherein the first electrode body 230, the second electrode body 240, and the third electrode body 250 are sequentially stacked from top to bottom, the first insulator 260 is located between the first electrode body 230 and the second electrode body 240, and the second insulator 270 is located between the second electrode body 240 and the third electrode body 250, different from the embodiment shown in fig. 3. In this embodiment, the connecting line of the first electrode body 230, the second electrode body 240 and the third electrode body 250 is parallel to the air outlet 111, the first electrode body 230 and the third electrode body 250 are connected to the high voltage end, and the second electrode body 240 is grounded, so that dielectric barrier discharge can be generated between the first electrode body 230 and the second electrode body 240 and between the second electrode body 240 and the third electrode body 250, more plasma can be generated, the efficiency is higher, and the sterilization effect is better.

Referring to fig. 6 to 10, a control method according to an embodiment of the present invention is described, and the control method is applied to the indoor unit 100 of an air conditioner according to an embodiment of the present invention, for controlling the generation of plasma and sterilizing the inside of the indoor unit 100 of an air conditioner. The control method of the air conditioner indoor unit of the embodiment can be executed by the control device 300 of the embodiment of the present invention.

Referring to fig. 6, the control method of the embodiment includes, but is not limited to, the following steps:

step S100: when the air-conditioning indoor unit 100 is in a stop state, the plasma device is controlled to be turned on to generate plasma, and the inside of the air-conditioning indoor unit 100 is sterilized by the plasma.

The operation stop state of the indoor unit 100 of the air conditioner can be understood as that the indoor unit 100 of the air conditioner stops a normal operation mode, but is still in a power supply state, so that normal power supply of the plasma device can be ensured, when the indoor unit 100 of the air conditioner stops operation, devices such as the wind wheel 130 and the evaporator 120 inside the indoor unit of the air conditioner stop operation, after the wind wheel 130 stops working, the inside air does not flow, at this time, the plasma device can be controlled to be started, and the plasma device generates plasma through the discharge of the electrode 200, and sterilization is performed by using the plasma.

Taking the embodiment shown in fig. 1 as an example for explanation, because the positive electrode 210 and the negative electrode 220 in the air duct 112 both face the direction of the wind wheel 130, and no air flow exists in the air duct 112 in a stopped state, the positive electrode 210 and the negative electrode 220 generate plasma through point discharge, and because the connecting line between the positive electrode 210 and the negative electrode 220 is parallel to the air outlet 111, under the action of the ion wind, the positive ions, the negative ions and the active substances can be diffused toward the direction of the wind wheel 130, and during the diffusion, the neutralization quantity of the positive ions and the negative ions can be effectively reduced, so that the plasma propagation distance is farther, the sterilization inside the air-conditioning indoor unit 100 is more effective, and the plasma can be concentrated inside, so that the plasma concentration is maintained at a higher concentration level, so that the plasma can effectively kill bacteria on the surfaces of devices such as the wind wheel 130, the evaporator 120, and the, effectively avoiding the bacteria breeding inside the indoor unit 100 of the air conditioner.

In some embodiments, before the plasma device is turned on, the inside of the air conditioning indoor unit 100 may be dried, and since the surface of the evaporator 120 may be attached with water vapor in the working modes of refrigeration, dehumidification and the like of the air conditioning indoor unit 100, the inside may be dried before plasma sterilization, which can reduce the protective effect of the water film on bacteria and effectively improve the sterilization effect.

Referring to fig. 7, the control method of the embodiment includes, but is not limited to, the following steps:

step S110: when the air-conditioning indoor unit 100 is in a stop operation state, controlling to operate a self-cleaning mode or a high-temperature mode, and drying the inside of the air-conditioning indoor unit 100;

step S120: after the drying is finished, the plasma device is controlled to be started to generate plasma, and the inside of the air conditioner indoor unit 100 is sterilized by the plasma.

The self-cleaning mode and the high-temperature mode are working modes of the air-conditioning indoor unit 100, the self-cleaning mode is to remove dust and water vapor on the surface of the evaporator 120 by using refrigeration, defrosting and high-temperature drying modes, the high-temperature mode is to directly remove water vapor by using heating and drying modes, and the specific working principles of the self-cleaning mode and the high-temperature mode are easily obtained by those skilled in the art and are not described again.

The air-conditioning indoor unit 100 can effectively remove internal water vapor by operating the self-cleaning module or the high-temperature module to achieve the drying purpose, so that the moisture on the surface of bacteria is reduced, the bacteria are killed by using the plasma after the drying is finished, the contact between ions and active substances and the surface of the bacteria is facilitated, the sterilization effect is effectively improved, and the sterilization efficiency is higher.

It should be noted that the plasma device may be automatically controlled to be turned on when the air-conditioning indoor unit 100 stops operating, or may be turned on according to a control command, where the control command may be a command for controlling the plasma device to be turned on, or may be a sterilization mode turning-on command. Of course, when the sterilization mode is started by the control command, it is necessary to satisfy that the indoor unit 100 of the air conditioner is in the operation stop state, and therefore, when the control is performed according to the sterilization module start command, the operation state of the indoor unit 100 of the air conditioner may be determined first.

Referring to fig. 8, in particular, in some embodiments, the control method includes, but is not limited to, the following steps:

step S200: receiving a sterilization mode starting instruction, and judging the working state of the indoor unit 100 of the air conditioner;

if the indoor air conditioner 100 is in the running state, starting a plasma device after the indoor air conditioner 100 stops running;

if the air-conditioning indoor unit 100 is in the stopped state, the plasma device is directly turned on.

Of course, steps S110 and S120 in the embodiment shown in fig. 7 may be performed before the plasma apparatus is turned on. For example, in the embodiment, a sterilization mode button may be set on the remote controller, and the sterilization mode opening instruction is sent out by the remote controller.

In some embodiments, the air-conditioning indoor unit 100 may also start the plasma device in a timed manner, specifically, the plasma device is started or stopped by using a timing module of the air-conditioning indoor unit 100, and the timing module may set the start time and the stop time of the plasma device, for example, the timing module sets a first set time, and after the air-conditioning indoor unit 100 stops operating, the plasma device is automatically started; for another example, the second set time is set by the timing module, and the plasma device is automatically turned off after the second set time passes.

Referring to fig. 9, in detail, the control method of the embodiment includes, but is not limited to, the following steps:

step S300: the operation of the indoor unit 100 of the air conditioner is stopped, and after a first set time, a plasma device is started;

In an embodiment, the first set time may be 30 minutes, 60 minutes, etc., and the second set time may be 60 minutes, 120 minutes, 150 minutes, etc., and the set time may be manually input through the timer module.

In some embodiments, when the plasma device is operated, the air deflector (not shown in the drawings) at the position of closing the air outlet 111 may be controlled, so as to reduce the diffusion of the plasma toward the outside of the indoor air conditioning unit 100 along the air outlet 111, so that the plasma may be concentrated inside, and thus the plasma concentration may be maintained at a higher concentration level, which effectively improves the sterilization effect and prevents bacteria from breeding inside the indoor air conditioning unit 100.

Referring to fig. 10, the control method of the embodiment includes the steps of:
