Description

Technical Field

[0001] The utility model relates to the technical field of air processing, in particular to an air conditioning device. Background Art

[0002] Negative oxygen water ions can release nano water ions and negative oxygen ions into the space. The main component of nano water ions is hydroxyl free radicals, which can kill bacteria. Negative oxygen ions can not only purify particulate matter, but also promote blood circulation in the body and inhibit the development of diseases.

[0003] Existing negative oxygen water ion generators use a method of directly ionizing air components. Because the air contains only 21% oxygen, only 1 / 5 of negative oxygen ions are produced during the ionization process, and the vast majority of the others are negative ions. The health-preserving effects of negative oxygen ions are limited.

[0004] In addition, the negative oxygen water ion generator adopts a fixed installation method, and the direction of ion transport cannot be adjusted. After the ions are generated, they are blown to a distant place driven by the wind field. On the one hand, the different directions of the wind field and the electric field can easily cause the ions to migrate closer; on the other hand, the life of negative ions is short. If they cannot be delivered to the surrounding areas of human activities in time, they will gradually disappear. A large number of ions are transmitted to invalid areas, resulting in a waste of negative oxygen water ions.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0053] The disclosure below provides many different embodiments or examples to realize different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplicity and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0054] In the related art, the negative oxygen water ion generator generates negative oxygen ions by ionizing air. However, since there is only 21% oxygen in the air, only about 1 / 5 of the air can be used to generate negative oxygen ions (negative oxygen ions are a type of gaseous negative ions) during the ionization process, and the remaining air generates negative ions other than negative oxygen ions. As a result, the concentration of negative oxygen ions generated by the negative oxygen water ion generator is low, which reduces the sterilization effect of negative oxygen ions.

[0055] In addition, negative ions have a short lifespan. If they cannot be delivered to the area around people in time, they will gradually disappear. Therefore, negative ions need to be delivered to the location of the person in time. The negative oxygen water ion generating device in the related art is usually arranged at the air outlet of the indoor unit. The flow of air-conditioning wind at the air outlet of the indoor unit can easily interfere with the movement of the ion wind. For example, in order to ensure the comfort of the air-conditioning wind, some air conditioners also include a "wind avoiding people" mode to avoid blowing the air-conditioning wind towards the human body. In this case, negative ions are more difficult to transport to the human body, and a large number of negative ions will be transmitted to the invalid area outside the location of the person, which can easily cause the waste of negative oxygen water ions, thereby reducing the air purification effect.

[0056] In addition, in the related art, the negative oxygen water ion generating device adopts a fixed installation method, and the direction of ion transport cannot be adjusted. The negative oxygen water ion generator cannot track the changes in the human body's position to achieve the effect of ion wind blowing on people, nor can it automatically adjust the oxygen content in the room.

[0057] In order to solve the above problems, some embodiments of the air conditioner provided by the present disclosure provide oxygen to the negative oxygen water ion generating device by setting an oxygen generator in the outdoor unit, so as to increase the oxygen content in the air around the negative oxygen water ion generator, thereby increasing the concentration of negative oxygen ions generated by the negative oxygen water ion generating device, thereby improving the sterilization effect of the air conditioner.

[0058] The negative oxygen water ion generator is arranged beside the first air outlet to prevent the air conditioning wind from interfering with the ion wind generated by the negative oxygen water ion generator. The negative oxygen water ion generator is rotatably connected to the indoor unit to adjust the ion transport direction.

[0059] The air conditioner of some embodiments of the present disclosure is also provided with an infrared sensor 4 to detect the position of indoor personnel, so that ion wind or oxygen can be delivered to the position of the personnel to ensure the air purification effect.

[0060] Air conditioning equipment refers to equipment that can regulate air. The functions of air conditioning equipment include cooling or heating the air, sterilizing and purifying the air, and increasing the oxygen concentration. Common air conditioning equipment includes air conditioners, purifiers, etc.

[0061] The following mainly takes the air conditioner as an example to explain the setting method of the negative oxygen water ion generating device in the air conditioning equipment.

[0062] like Figure 1A and Figure 1B As shown, some embodiments of the present disclosure provide an air conditioner 1000. The air conditioner 1000 includes an indoor unit 1, an outdoor unit 20, and a pipeline 70. The indoor unit 1 and the outdoor unit 20 are connected by the pipeline 70 to transmit refrigerant.

[0063] In some embodiments, the outdoor unit 20 includes a compressor 201 , which is configured to compress the refrigerant so that the low-pressure refrigerant is compressed to form a high-pressure refrigerant.

[0064] In some embodiments, the outdoor unit 20 further includes an outdoor heat exchanger 203, which is configured to perform heat exchange between outdoor air and the refrigerant transmitted in the outdoor heat exchanger 203. For example, the outdoor heat exchanger 203 works as a condenser in the cooling mode of the air conditioner 1000, so that the refrigerant compressed by the compressor 201 condenses by dissipating heat to the outdoor air through the outdoor heat exchanger 203. The outdoor heat exchanger 203 works as an evaporator in the heating mode of the air conditioner 1000, so that the decompressed refrigerant absorbs the heat of the outdoor air through the outdoor heat exchanger 203 and evaporates.

[0065] In some embodiments, the outdoor heat exchanger 203 includes heat exchange fins to expand the contact area between the outdoor air and the refrigerant transmitted in the outdoor heat exchanger 203, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0066] In some embodiments, the outdoor unit 20 further includes an outdoor fan 204, which is configured to draw outdoor air into the outdoor unit 20 through the outdoor air inlet of the outdoor unit 20, and send the outdoor air after heat exchange with the outdoor heat exchanger 203 out through the outdoor air outlet of the outdoor unit 20. The outdoor fan 204 provides power for the flow of outdoor air.

[0067] In some embodiments, the indoor unit 1 includes an indoor heat exchanger 60. The indoor heat exchanger 60 is configured to perform heat exchange between indoor air and the refrigerant transmitted in the indoor heat exchanger 60. For example, the indoor heat exchanger 60 works as an evaporator in the cooling mode of the air conditioner 1000, so that the refrigerant after heat dissipation through the outdoor heat exchanger 203 absorbs the heat of the indoor air through the indoor heat exchanger 60 and evaporates. The indoor heat exchanger 60 works as a condenser in the heating mode of the air conditioner 1000, so that the refrigerant after heat absorption through the outdoor heat exchanger 203 dissipates the heat to the indoor air through the indoor heat exchanger 60 and condenses.

[0068] In some embodiments, the indoor heat exchanger 60 includes heat exchange fins to expand the contact area between the indoor air and the refrigerant transmitted in the indoor heat exchanger 60, thereby improving the heat exchange efficiency between the indoor air and the refrigerant.

[0069] like Figure 1A and Figure 1B As shown, the indoor unit 1 further includes a first fan 30, which is configured to suck indoor air into the indoor unit 1 through a first air inlet 13 of the indoor unit 1, and send the indoor air after heat exchange with the indoor heat exchanger 60 out through a first air outlet 11 of the indoor unit 1. The first fan 30 provides power for the flow of indoor air.

[0070] In some embodiments, the outdoor unit 20 further includes an expansion valve 205, which is connected between the outdoor heat exchanger 203 and the indoor heat exchanger 60. The opening of the expansion valve 205 adjusts the pressure of the refrigerant flowing through the outdoor heat exchanger 203 and the indoor heat exchanger 60 to adjust the flow of the refrigerant flowing between the outdoor heat exchanger 203 and the indoor heat exchanger 60. The flow and pressure of the refrigerant flowing between the outdoor heat exchanger 203 and the indoor heat exchanger 60 will affect the heat exchange performance of the outdoor heat exchanger 203 and the indoor heat exchanger 60. The expansion valve 205 can be an electronic valve. The opening of the expansion valve 205 is adjustable to control the flow and pressure of the refrigerant flowing through the expansion valve 205.

[0071] In some embodiments, the compressor 201, the outdoor heat exchanger 203, the expansion valve 205 and the indoor heat exchanger 60 connected in sequence form a refrigerant circuit, in which the refrigerant circulates and exchanges heat with the air through the outdoor heat exchanger 203 and the indoor heat exchanger 60, respectively, to achieve the cooling mode or the heating mode of the air conditioner 1000. The four-way valve 202 is connected to the refrigerant circuit, and the four-way valve 202 is configured to switch the flow direction of the refrigerant in the refrigerant circuit so that the air conditioner 1000 performs the cooling mode or the heating mode.

[0072] In some embodiments, reference Figure 2A The indoor unit 1 further includes a housing 10, and a mounting cavity is formed in the housing 10 for arranging components such as an indoor heat exchanger 60 and a first fan 30.

[0073] In some embodiments, the indoor unit 1 further includes a first air outlet 11. For example, the first air outlet 11 is disposed on a side (such as the front side) of the housing 10 facing the user.

[0074] In some embodiments, the indoor unit 1 further includes a first air inlet 13. For example, the first air inlet 13 is disposed on a side (such as a rear side) of the housing 10 opposite to the side where the first air outlet 11 is located.

[0075] Under the action of the first fan 30, the indoor air flows to the indoor heat exchanger 60 through the first air inlet 13, and after being cooled or heated by the indoor heat exchanger 60, flows out from the first air outlet 11, thereby achieving the function of regulating the indoor air temperature.

[0076] In some embodiments, the indoor unit 1 further includes an air guide plate 12, which is disposed at the first air outlet 11. The air conditioner 1000 adjusts the flow direction of the air-conditioned wind blown out from the first air outlet 11 through the air guide plate 12. It should be noted that the wind blown out through the first air outlet 11 is the air-conditioned wind. For example, the air-conditioned wind includes cold wind, hot wind, or outdoor fresh air.

[0077] In some embodiments, the air conditioner 1000 further includes a negative ion generating device, which is disposed in the indoor unit 1. The negative ion generating device is configured to release negative ions into the indoor space 2.

[0078] Since most particles in the air are positively charged, negative ions can combine with positively charged particles such as bacteria, dust, and smoke in the air to make these particles negatively charged. Negatively charged particles and positively charged particles attract each other, gather together, and fall, thereby achieving the purpose of air purification. In addition, some particles combine with negative oxygen ions and become negatively charged. Under the action of the electric field force, the negatively charged particles will move toward the grounded object and eventually settle on the surface of the grounded object, thereby achieving the effect of purifying the air.

[0079] In some embodiments, the negative ion generating device is disposed at the first air outlet 11, and the negative ions are blown into the room along with the air-conditioning wind.

[0080] In some embodiments, the negative ion generating device is disposed on the gas flow path between the first air outlet 11 and the first air inlet 13 , and the negative ions are blown toward the indoor space 2 along with the air flow.

[0081] In some embodiments, the negative ion generating device is a negative oxygen water ion generating device 50 , and the negative oxygen water ion generating device 50 is configured to release negative oxygen ions and nano water ions into the indoor space 2 .

[0082] Negative oxygen ions have a good purification effect on particulate matter, and also have good health-care effects such as promoting blood circulation in the body and inhibiting the development of diseases. The main component of nano water ions is hydroxyl free radicals, which have a killing effect on bacteria and viruses.

[0083] In some embodiments, the negative oxygen water ion generator 50 is disposed beside the first air outlet 11, that is, the negative oxygen water ion generator 50 is not disposed in the first air outlet 11. The direction adjustment of the air conditioning wind blown out from the first air outlet 11 and the ion wind 3 blown out from the negative oxygen water ion generator 50 is independent of each other, that is, the air conditioning wind and the ion wind 3 are independently controlled.

[0084] For example, the air conditioner 1000 adjusts the air guide plate 12 to achieve the goal of "wind avoiding people" for the air-conditioning wind, that is, to avoid the air-conditioning wind from blowing directly on people, thereby improving the comfort of blowing.

[0085] The air conditioner 1000 adjusts the air outlet angle of the negative oxygen water ion generating device 50 to achieve the "wind blowing on people" of the ion wind 3, so that the ion wind 3 blows near people, giving full play to the health-preserving effect of negative oxygen ions on the human body.

[0086] In some embodiments, the negative oxygen water ion generator 50 can be operated independently when the indoor unit 1 is shut down. For example, when the indoor temperature is suitable, there is no need to turn on the indoor unit 1 to adjust the temperature of the indoor air. At this time, only the negative oxygen water ion generator 50 can be turned on to provide nano water ions and negative oxygen ions to the room to improve the indoor air quality.

[0087] In some embodiments, reference Figure 3 The indoor unit 1 further includes a third air duct 14, which is connected to the first air inlet 13 and the first air outlet 11. Indoor air enters the indoor unit 1 through the first air inlet 13 and enters the indoor space 2 through the third air duct 14 and the first air outlet 11. The third air duct 14 is a flow duct for air-conditioning wind.

[0088] In some embodiments, reference Figure 3 The indoor unit 1 further includes a first air duct 400 (such as an air supply duct), and the first air duct 400 is configured to provide ionized air to the negative oxygen water ion generating device 50. It should be noted that the air duct for the air conditioning wind is independently configured to the first air duct 400.

[0089] By arranging the first air duct 400 of the negative oxygen water ion generating device 50 independently from the third air duct 14 , the negative oxygen water ion generating device 50 can still be turned on to blow ions into the indoor space 2 when the indoor unit 1 is turned off.

[0090] In some embodiments, reference Figure 3 and Figure 4 The air inlet of the first air duct 400 is located on the air inlet side of the indoor heat exchanger 60, so that the air entering the first air duct 400 is air that has not been heat exchanged by the indoor heat exchanger 60, thereby avoiding the temperature change of the air affecting the ionization effect of the negative oxygen water ion generating device 50.

[0091] In some embodiments, reference Figure 5 The indoor unit 1 further includes a second fan 500 (eg, an auxiliary fan). The second fan 500 is disposed in the first air duct 400, and the second fan 500 is configured to provide gas flow power in the first air duct 400 to increase the blowing distance of the ion wind 3.

[0092] In some embodiments, reference Figure 2B The indoor unit 1 further includes an infrared sensor 4, which is configured to detect the position of indoor personnel.

[0093] In some embodiments, the indoor unit 1 further includes a controller 8 , which is coupled to the infrared sensor 4 and the second fan 500 to obtain location information of people in the indoor space 2 .

[0094] The controller 8 may be a chip or a processor. For example, the processor may be a general-purpose central processing unit (CPU), a microprocessor, or an application-specific integrated circuit (ASIC). Alternatively, the controller 8 may be a programmable device, including a complex programmable logic device (CPLD), an erasable programmable logic device (EPLD), or a field programmable gate array (FPGA). The chip may be an integrated circuit (IC).

[0095] The controller 8 determines the distance D between the person and the air outlet according to the detection information of the infrared sensor 4. It should be noted that since the first air outlet 11 and the negative oxygen water ion generating device 50 are both arranged on the front side of the indoor unit 1, the air outlet here can be an air outlet for air conditioning wind or an air outlet for ion wind.

[0096] The second fan 500 is selectively turned on according to the size relationship between D and the preset distance Dt, so that the ion wind 3 blown out by the negative oxygen water ion generating device 50 can reach the position where the personnel are located.

[0097] If it is determined that the distance D between the person and the first air outlet 11 is ≥ the preset distance Dt, that is, when the person is far away from the first air outlet 11, the second fan 500 is turned on to increase the blowing distance of the ion wind 3 to ensure that the ion wind 3 can be blown to the person.

[0098] If it is determined that the distance D between the person and the first air outlet 11 is less than the preset distance Dt, that is, when the person is relatively close to the first air outlet 11, the second fan 500 is turned off, and positive pressure is generated inside the indoor unit 1 by relying on the power of the first fan 30, so that a certain airflow is also generated in the first air duct 400, and the ions are blown to the person under the action of the airflow.

[0099] In some embodiments, the second fan 500 is a variable frequency fan. Since the rotation speed of the variable frequency fan is adjustable, the accuracy of controlling the transmission distance of the ion wind 3 can be improved.

[0100] In some embodiments, the controller 8 is further configured to:

[0101] The spatial position coordinates of the person in the room are detected by the infrared sensor 4, and the distance D between the person and the first air outlet 11 is calculated based on the coordinates.

[0102] The operating frequency of the second fan 500 is automatically adjusted according to the distance D, and the operating frequency of the second fan 500 is positively correlated with the distance D. That is, the greater the distance D, the greater the operating frequency of the second fan 500, and the smaller the distance D, the smaller the operating frequency of the second fan 500.

[0103] According to the position coordinates of the person, the rotation angle of the negative oxygen water ion generating device 50 is controlled to make the ion wind 3 blow around the human body.

[0104] The start and stop and the rotation frequency of the second fan 500 are adjusted according to the distance between the person and the first air outlet 11. In this way, not only the ion wind 3 can be blown around the human body, but also the wind volume and wind speed of the ion wind 3 can be within the preset range, avoiding excessive wind feeling and causing discomfort to the user.

[0105] In some embodiments, reference Figure 2B , Figure 5 and Figure 6 The outdoor unit 1 further includes an oxygen generator 5 , which is configured to provide oxygen to the first air duct 400 .

[0106] In this way, oxygen is provided to the first air duct 400 through the oxygen generator 5, thereby increasing the oxygen concentration in the air ionized by the negative oxygen water ion generating device 50, and then increasing the concentration of negative oxygen ions generated by the negative oxygen water ion generating device 50, so as to improve the health-care effect on the human body.

[0107] In some embodiments, the air conditioner 1000 includes a cooling mode. When the cooling mode is turned on, the air conditioner 1000 cools the indoor air.

[0108] In some embodiments, the air conditioner 1000 further includes a heating mode. When the heating mode is turned on, the air conditioner 1000 heats the indoor air.

[0109] In some embodiments, the air conditioner 1000 further includes a health care mode. When the health care mode is turned on, the negative oxygen water ion generating device 50 is turned on to release negative oxygen ions and nano water ions into the indoor space 2.

[0110] In some embodiments, the health care mode has an oxygen supply function. When the oxygen supply function is turned on, the oxygen generator 5 is turned on to provide oxygen to the first air duct 400.

[0111] In some embodiments, the oxygen concentrator 5 is selectively turned on according to the indoor oxygen concentration.

[0112] In some embodiments, the indoor unit 1 further includes a first sensor 6. For example, the first sensor 6 is an oxygen concentration sensor, and the oxygen concentration sensor is disposed at the first air inlet 13, and the first sensor 6 is configured to detect the oxygen concentration X at the first air inlet 13.

[0113] In some embodiments, the controller 8 is coupled to the first sensor 6 and the oxygen concentrator 5, and the controller 8 is further configured to:

[0114] The oxygen concentration X at the first air inlet 13 detected by the first sensor 6 is obtained.

[0115] If it is determined that the oxygen concentration X is less than the first limit value X1, it means that the oxygen concentration in the room is low. At this time, the oxygen generator 5 is turned on, and high-concentration oxygen flows through the first air duct 400 to the emission electrode 300 of the negative oxygen water ion generating device 50, thereby increasing the concentration of negative oxygen ions generated by ionization.

[0116] If it is determined that the oxygen concentration X is between the first limit value X1 and the second limit value X2, that is, X1≤X<X2, it means that the oxygen concentration in the room is within a reasonable range. At this time, the oxygen generator 5 maintains the operating state and continues to supply oxygen to the room.

[0117] If it is determined that the oxygen concentration X ≥ the second limit value X2, it means that the oxygen concentration in the room is at a high value within a reasonable range. At this time, the oxygen concentrator 5 is turned off and the oxygen concentration in the room will gradually decrease. Afterwards, if it is determined that the oxygen concentration in the room decreases to X1≤X<X2, the oxygen concentrator 5 remains turned off at this time. If it is determined that the oxygen concentration in the room decreases to less than the first limit value X1, the oxygen concentrator 5 is turned on again to complete a cycle.

[0118] In some embodiments, reference Figure 5 The first air duct 400 includes a first sub-air duct 410, and the air inlet of the first sub-air duct 410 is located at the air inlet side of the indoor heat exchanger 60. The air that has not been heat exchanged by the indoor heat exchanger 60 is supplied to the negative oxygen water ion generating device 50 through the first sub-air duct 410.

[0119] It can be understood that the first sub-air duct 410 is independent of the third air duct 14, that is, the air conditioning air duct of the indoor unit 1, so that independent control of the air conditioning wind and the ion wind 3 can be achieved.

[0120] In some embodiments, the second fan 500 is disposed at the air inlet of the first sub-air duct 410. After the second fan 500 is turned on, the gas flow rate in the first sub-air duct 410 can be increased, thereby increasing the transport distance of the ions generated by the negative oxygen water ion generating device 50.

[0121] In some embodiments, the first air duct 400 further includes a second sub-air duct 420, which is connected to the oxygen outlet of the oxygen generator 5 through a pipeline. The air conditioner 1000 provides oxygen to the second sub-air duct 420 through the oxygen generator 5, thereby increasing the oxygen concentration around the emission electrode 300 of the negative oxygen water ion generating device 50, increasing the concentration of negative oxygen ions generated by ionization, and thus helping to improve the oxygen health effect of the human body.

[0122] In some embodiments, reference Figures 7 to 14 The negative oxygen water ion generating device 50 includes an emitting electrode 300. The emitting electrode 300 is configured to release negative oxygen ions and nano water ions into the indoor space 2. The air that has not been heat exchanged by the indoor heat exchanger 60 can be supplied to the emitting electrode 300 of the negative oxygen water ion generating device 50 via the first sub-air duct 410.

[0123] The structure of the emitting electrode 300 is shown in FIG. Fig.23 The emitting electrode 300 can be made of a carbon fiber porous rod material, which contains a strong water absorption factor that can absorb water from the air and ionize water into nano water ions under high voltage conditions.

[0124] For example, the emitting electrode 300 includes a water-absorbing factor and a carbon fiber bundle. After the epoxy resin is cured, the carbon fiber bundle is carbonized at high temperature to form a porous carbon fiber rod structure, and one end is processed into a hemispherical emitting tip through mechanical processing. After the processing is completed, the water-absorbing factor is immersed into the carbon fiber bundle through ultrasonic infiltration to make a high-efficiency water-absorbing electrode.

[0125] In some embodiments, reference Fig.11 The negative oxygen water ion generating device 50 also includes a negative high voltage power supply 600 , which is configured to provide a negative high voltage to the emitting electrode 300 .

[0126] In some embodiments, reference Figure 7 The negative oxygen water ion generating device 50 further includes a rotating part 100, and the rotating part 100 is configured to adjust the ion transport direction. The emitting electrode 300 can be disposed on the rotating part 100 to rotate with the rotating part 100.

[0127] In some embodiments, the rotating part 100 is configured to rotate in a first plane extending in a transverse direction to drive the emission electrode 300 to rotate in the first plane and adjust the transport direction of ions in the first plane. For example, the first plane is a horizontal plane.

[0128] In some embodiments, the rotating part 100 is configured to rotate in a second plane extending vertically to drive the emission electrode 300 to rotate in the second plane and adjust the transport direction of ions in the second plane. For example, the second plane is a vertical plane.

[0129] In some embodiments, the rotating portion 100 is configured to rotate simultaneously in a first plane and a second plane, wherein the first plane extends in a lateral direction and the second plane extends in a vertical direction, so as to adjust the transport direction of ions in a three-dimensional space.

[0130] When the rotating part 100 rotates in the first plane (ie, the horizontal plane), it drives the emission electrode 300 to rotate in the horizontal plane, thereby realizing the transport adjustment of ions in different directions in the horizontal plane. Fig.12 , the maximum rotatable angle of the rotating part 100 in the horizontal plane is a°.

[0131] When the rotating part 100 rotates in the second plane (ie, the vertical plane), it drives the emission electrode 300 to rotate in the vertical plane, thereby realizing the transport adjustment of ions in different directions in the vertical plane. Fig.13 , the maximum rotatable angle of the rotating part 100 in the horizontal plane is b°.

[0132] In some embodiments, a second air channel 110 (such as an air channel) is formed in the rotating part 100, and the second air channel 110 includes a second air inlet 150, and the second air inlet 150 of the second air channel 110 is connected to the first air channel 400. The emitting electrode 300 is arranged in the second air channel 110. In this way, the gas provided by the first air channel 400 can flow into the second air channel 110 and fully contact the emitting electrode 300. In this way, the emitting electrode 300 can fully ionize the air and improve the ionization effect.

[0133] In some embodiments, reference Fig.10 , Fig.11 , Fig.15 as well as Fig.16 The negative oxygen water ion generating device 50 further includes an electrode mounting seat 130 . The electrode mounting seat 130 is disposed in the second air duct 110 of the rotating part 100 , and the emitting electrode 300 is inserted on the electrode mounting seat 130 .

[0134] In some embodiments, the second air duct 110 further includes a second air outlet 140 . The second air outlet 140 is disposed on the rotating portion 100 , and the ions generated by the emitting electrode 300 flow out from the second air outlet 140 .

[0135] In some embodiments, the emission tip of the emission electrode 300 extends out through the second air outlet 140 to facilitate ion diffusion and escape.

[0136] In some embodiments, the gas in the second air duct 110 flows from the outer peripheral side of the electrode mounting seat 130 to the second air outlet 140, so that the gas in the second air duct 110 wraps the emission tip of the emission electrode 300, ensuring that the emission tip is in full contact with the air and improving the ionization effect.

[0137] The emitting electrode 300 is placed in the second air duct 110. The gas flow rate in the second air duct 110 affects the ion transport speed. The gas flow rate in the second air duct 110 is controlled by the second fan 500, thereby controlling the ion transport distance and ensuring that the ions can be transported around the human body.

[0138] In some embodiments, the negative oxygen water ion generating device 50 further includes a plurality of connecting ribs 120, and the electrode mounting seat 130 is connected to the inner wall of the second air duct 110 through the plurality of connecting ribs 120 to achieve the installation of the electrode mounting seat 130 in the second air duct 110. In some embodiments,

[0139] The electrode mounting seat 130 faces the second air outlet 140 , so that the emission tip of the emission electrode 300 faces the second air outlet 140 , thereby allowing the ions released by the emission electrode 300 to flow out of the second air outlet 140 .

[0140] There is a preset distance between the electrode mounting seat 130 and the inner wall of the second air duct 110 , and the distance becomes a gap for gas circulation, so that the gas in the second air duct 110 can wrap the emission tip.

[0141] In some embodiments, the electrode mounting seat 130 includes a mounting seat body 135 and a mounting cavity 132. The mounting cavity 132 passes through the mounting seat body 135. The rear end of the emitter electrode 300 is inserted into the mounting cavity 132 through the first end opening (such as the front side opening) of the mounting cavity 132 to be fixed to the electrode mounting seat 130. The emission tip of the emitter electrode 300 extends from the mounting cavity 132 and faces the second air outlet 140, so that the emission tip is fully in contact with the air to ensure the smooth diffusion and escape of ions.

[0142] In some embodiments, reference Fig.11 The negative oxygen water ion generating device 50 further includes a high voltage line 160, one end of which is coupled to the negative high voltage power supply 600, and the other end of which is coupled to the emitting electrode 300. The other end of the high voltage line 160 is inserted into the mounting cavity 132 through the second end opening of the mounting cavity 132 to supply power to the emitting electrode 300.

[0143] In this way, the emitter electrode 300 and the high voltage line 160 are mounted to the electrode mounting base 130 from different sides, which facilitates installation.

[0144] In some embodiments, the second air inlet 150 of the second air duct 110 is directly connected to the second air outlet 140, and the gas flowing in from the second air inlet 150 flows to the second air outlet 140 without turning. In this way, the wind loss is small, and the narrow and long air duct has a certain acceleration effect on the airflow, which helps to increase the transport distance of ions.

[0145] In some embodiments, the high-voltage wire 160 extends into the installation cavity 132 through the second air inlet 150 of the second air duct 110. In this way, the rotating part 100 does not need to be provided with a special threading hole for the high-voltage wire 160, which facilitates the installation of the high-voltage wire 160.

[0146] In some embodiments, reference Fig.10 , Fig.11 as well as Fig.15 The electrode mounting seat 130 further includes a limiting portion 131 , and the limiting portion 131 (such as a limiting step) is disposed on the inner wall of the mounting cavity 132 .

[0147] The installation cavity 132 includes a first sub-installation cavity 1321 and a second sub-installation cavity 1322. The first sub-installation cavity 1321 is formed between the limiting portion 131 and the first end opening of the installation cavity 132, and the second sub-installation cavity 1322 is formed between the limiting portion 131 and the second end opening of the installation cavity 132.

[0148] The electrode mounting seat 130 further includes a connecting portion 133 (such as a groove), which is disposed on the inner wall of the mounting cavity 132 , and the connecting portion 133 passes through the first sub-mounting cavity 1321 and the second sub-mounting cavity 1322 .

[0149] The rear end of the emitting electrode 300 abuts against the limiting portion 131 , and the high-voltage wire 160 is inserted into the second sub-mounting cavity 1322 .

[0150] It is understandable that when the emitting electrode 300 is inserted into the installation cavity 132, when the emitting electrode 300 abuts against the limiting portion 131, it indicates that the emitting electrode 300 is inserted into place. The setting of the limiting portion 131 can limit the insertion distance of the emitting electrode 300, ensuring that the depths of emitting electrodes 300 of different batches inserted into the installation cavity 132 are the same.

[0151] In some embodiments, the negative oxygen water ion generating device 50 further includes a conductive carbon paste 170. A portion of the conductive carbon paste 170 is filled in the second sub-mounting cavity 1322, and another portion of the conductive carbon paste 170 flows into the first sub-mounting cavity 1321 through the connecting portion 133 to wrap the emitter electrode 300.

[0152] It should be noted that the material of the conductive carbon paste 170 mainly includes epoxy resin and carbon powder, which has conductivity. On the one hand, the setting of the conductive carbon paste 170 plays a role of conduction and fixation. The conductive carbon paste 170 realizes the coupling between the emitter electrode 300 and the high-voltage line 160, and the conductive carbon paste 170 also plays a role of fixing the emitter electrode 300.

[0153] Since the emitter electrode 300 contains a water absorption factor, after the emitter electrode 300 absorbs water, if the high-voltage line 160 directly contacts the emitter electrode 300, under negative high voltage conditions, the copper wire of the high-voltage line 160 will lose electrons and then electrochemical corrosion will occur. Therefore, the emitter electrode 300 and the high-voltage line 160 are coupled by conductive carbon paste 170, which can avoid direct contact between the emitter electrode 300 and the high-voltage line 160, thereby avoiding electrochemical corrosion of the copper wire of the high-voltage line 160.

[0154] On the other hand, the provision of the conductive carbon paste 170 can also play a fixing role, and the other part of the conductive carbon paste 170 flows into the first sub-mounting cavity 1321 through the connecting portion 133, and can wrap the emitting electrode 300. In this way, it is helpful to further improve the conductivity of the negative oxygen water ion generating device 50, and it is beneficial to improve the fixing effect on the emitting electrode 300.

[0155] In some embodiments, the installation process of the emitter electrode 300 includes:

[0156] One end of the high voltage wire 160 is exposed to expose the inner copper wire, for example, 5 mm to 8 mm.

[0157] The exposed copper wire end is extended into the second sub-mounting cavity 1322 from the second end opening of the mounting cavity 132 .

[0158] The conductive carbon paste 170 is poured into the second sub-mounting cavity 1322 from the first end opening of the mounting cavity 132 so that the conductive carbon paste 170 wraps the copper wire. After the conductive carbon paste 170 is poured in, it should be higher than the limiting portion 131 , and a part of the conductive carbon paste 170 enters the first sub-mounting cavity 1321 .

[0159] The emitter electrode 300 is inserted into the first sub-mounting cavity 1321 through the first end opening of the mounting cavity 132 until the emitter electrode 300 abuts against the limiting portion 131. During the insertion of the emitter electrode 300, the conductive carbon paste 170 is squeezed and the conductive carbon paste 170 wraps the root of the emitter electrode 300 to enhance the conductivity.

[0160] After the installation is completed, the conductive carbon paste 170 is completely cured by standing for a period of time, such as 24 hours. At this time, the emitter electrode 300 is firmly installed in the installation cavity 132 .

[0161] In some embodiments, the working principle of the negative oxygen water ion generating device 50 includes: the negative high-voltage power supply 600 transmits the high voltage to the conductive carbon slurry 170 through the high-voltage line 160, and then transmits it to the carbon fiber electrode of the emitting electrode 300. The carbon fiber electrode contains a large amount of water absorption factors and can directly absorb moisture from the air. The carbon fiber electrode is composed of countless carbon fibers arranged in sequence, and each carbon fiber end is equivalent to an emission tip. Therefore, a large number of emission tips are similarly designed at the electrode end to ionize the water in the electrode and the oxygen in the air to produce nano-water ions rich in hydroxyl free radicals and high-concentration negative oxygen ions, which are discharged into the air from the second air outlet 140 to purify the microorganisms, particulate matter, volatile organic compounds (VOCs) and other pollutants in the indoor space 2 to increase the oxygen content of the indoor air.

[0162] In some embodiments, reference Fig.11 and Fig.16 The electrode mounting seat 130 further includes an air guiding surface 134, which is disposed on an outer wall of one end of the mounting seat body 135 facing the second air inlet 150 of the second air duct 110, so as to guide the air and reduce the air flow resistance and noise.

[0163] In some embodiments, the negative oxygen water ion generating device 50 further includes a mounting portion 200 , and the rotating portion 100 is mounted on the indoor unit 1 through the mounting portion 200 .

[0164] It is understandable that the mounting portion 200 serves as a mounting carrier of the rotating portion 100 and can achieve a rotational connection with the rotating portion 100 .

[0165] For example, refer to Figure 7 and Fig.17 The mounting portion 200 includes a mounting portion body 230 and a first matching portion 212. The mounting portion body 230 includes a mounting space 240, and the mounting space 240 is configured to mount the rotating portion 100. The first matching portion 212 is disposed on a side wall of the mounting portion body 230 that forms the mounting space 240. For example, the first matching portion 212 is disposed on the inner walls of two side walls of the mounting portion body 230 that are opposite to each other.

[0166] The rotating part 100 includes a rotating part body 111 and a second matching part 190. The second matching part 190 is disposed on the outer wall of the rotating part body 111. The first matching part 212 matches with the second matching part 190 to rotatably clamp the rotating part 100 in the installation space 240.

[0167] In some embodiments, the outer contour of the rotating part 100 is spherical, two first matching parts 212 are provided and arranged oppositely, and the first matching parts 212 are concave, and the concave contour is adapted to the spherical contour of the rotating part 100. In this way, it can not only achieve clamping with the rotating part 100, but also ensure the rotation of the rotating part 100.

[0168] In some embodiments, the mounting portion 200 includes two first mounting arms 210 arranged at an interval relative to each other, a mounting space 240 is formed between the two first mounting arms 210, and a first matching portion 212 is provided on the side wall of any one of the two first mounting arms 210 facing the mounting space 240. The first matching portions 212 are respectively provided on the opposite sides of the two first mounting arms 210. In this way, the mounting portion 200 clamps the rotating portion 100 from the opposite sides of the rotating portion 100, which can improve the reliability of the clamping structure.

[0169] In some embodiments, the mounting portion 200 further includes two extension portions 211. The two extension portions 211 are respectively disposed at one end of the two first mounting arms 210 close to the rotating portion 100 and extend downward. The first matching portion 212 is disposed at one side of any one of the two extension portions 211 close to the rotating portion 100.

[0170] The extension portion 211 has a preset volume, which provides a sufficiently large setting and molding space for the first matching portion 212 , increases the area of ​​the first matching portion 212 , and helps to improve the clamping reliability of the rotating portion 100 .

[0171] In some embodiments, the mounting portion 200 further includes a second mounting arm 220 connected between the two first mounting arms 210. For example, the second mounting arm 220 is connected to one end of the two first mounting arms 210 away from the rotating portion 100 so as not to interfere with the installation of the rotating portion 100.

[0172] In some embodiments, the negative oxygen water ion generating device 50 further includes a driving unit 700, which is configured to drive the rotating unit 100 to rotate in a three-dimensional space to adjust the ion transport direction.

[0173] The driving unit 700 is configured to drive the rotating unit 100 to rotate in at least one of the first plane or the second plane to adjust the ion transport direction. In some embodiments, the first plane is set as a horizontal plane and the second plane is set as a vertical plane.

[0174] For example, the driving unit 700 is configured to drive the rotating unit 100 to rotate along a first plane extending horizontally, and adjust the transport direction of ions in the first plane.

[0175] The driving unit 700 is configured to drive the rotating unit 100 to rotate along a second plane extending vertically, and adjust the transport direction of ions in the second plane.

[0176] The driving unit 700 is configured to drive the rotating unit 100 to rotate simultaneously in a first plane and a second plane, wherein the first plane extends in a lateral direction and the second plane extends in a vertical direction, so as to adjust the transport direction of ions in a three-dimensional space.

[0177] In some embodiments, reference Figure 7 , Figure 8 as well as Fig.10 The driving part 700 includes a first sub-driving part 710, and a power output shaft of the first sub-driving part 710 is connected to the rotating part 100. The first sub-driving part 710 is configured to drive the rotating part 100 to rotate in a first plane extending in the transverse direction.

[0178] In some embodiments, the first sub-driving unit 710 is a horizontal stepping motor, and the motor shaft of the motor is connected to the rotating unit 100 .

[0179] In some embodiments, the first sub-driving unit 710 is disposed on the top of the rotating unit 100. The power output shaft of the first sub-driving unit 710 is directly opposite to the spherical center of the rotating unit 100.

[0180] In some embodiments, reference Fig.19 The first sub-driving unit 710 includes a first sub-driving unit body 715, a power output shaft 716 and a clamping portion 711 (such as a rectangular body). For example, the clamping portion 711 is disposed at one end of the power output shaft 716 and is processed into a rectangular body. A first pin hole 712 is disposed on the clamping portion 711.

[0181] Reference Fig.18 The rotating part 100 further includes a first mounting member 180. The first mounting member 180 is disposed on the top of the rotating part body 111. A mounting hole 181 (such as a rectangular mounting hole) is disposed on the first mounting member 180, and a second latch hole 182 is disposed on the side wall of the mounting hole 181. The clamping part 711 is inserted into the mounting hole 181, and the latch passes through the first latch hole 712 and the second latch hole 182 to fix the clamping part 711 to the mounting hole 181, thereby achieving fixed installation of the first sub-driving part 710 and the rotating part 100.

[0182] It is understandable that, referring to Fig.12 , the power output shaft of the first sub-driving unit 710 rotates, driving the rotating unit 100 to rotate in the horizontal plane.

[0183] In some embodiments, the driving unit 700 further includes a second sub-driving unit 720, and the second sub-driving unit 720 is fixedly disposed on the mounting unit 200. For example, the second sub-driving unit 720 is fixedly disposed on the second mounting arm 220.

[0184] The driving part 700 further includes a transmission connecting rod assembly 730, which is disposed between the power output shaft of the second sub-driving part 720 and the first sub-driving part 710. The second sub-driving part 720 is configured to drive the rotating part 100 to rotate in a second plane extending in the vertical direction.

[0185] For example, the second sub-driving unit 720 is a vertical stepping motor, and the motor shaft of the motor is connected to the transmission connecting rod assembly 730 .

[0186] The transmission connecting rod assembly 730 includes a first connecting rod 731 and a second connecting rod 732, wherein the first connecting rod 731 is rotatably connected to the second connecting rod 732. One end of the first connecting rod 731 is rotatably connected to the first sub-driving unit 710. One end of the second connecting rod 732 is fixedly connected to the power output shaft of the second sub-driving unit 720.

[0187] Reference Fig.13 The second sub-driving unit 720 rotates, and drives the first sub-driving unit 710 to move through the transmission action of the first connecting rod 731 and the second connecting rod 732. The first sub-driving unit 710 then transmits the force to the rotating unit 100, thereby realizing the rotation of the rotating unit 100 in the vertical plane. Fig.14 The rotating postures of the rotating part 100 at various different angular positions are shown.

[0188] In some embodiments, reference Figure 8 and Fig. 20 The first sub-driving unit 710 further includes a second mounting member 713 , and the second mounting member 713 is disposed on one side of the first sub-driving unit body 715 close to the second sub-driving unit 720 .

[0189] In some embodiments, the second mounting member 713 includes a second mounting member body 717 and a mounting shaft 714 . The mounting shaft 714 is disposed on one side of the second mounting member body 717 close to the second sub-driving unit 720 . One end of the first connecting rod 731 is rotatably connected to the mounting shaft 714 .

[0190] In some embodiments, the driving unit 700 is located above the rotating unit 100 , so that it is convenient to connect the first air duct 400 , the high-voltage line 160 , etc. to the rotating unit 100 from below the second mounting arm 220 .

[0191] In some embodiments, the horizontal rotation of the rotating part 100 is controlled by the first sub-driving part 710, and the vertical rotation of the rotating part 100 is controlled by the second sub-driving part 720. The two directions can be adjusted simultaneously, and the adjustments in the two directions do not affect each other, which helps to improve the adjustment efficiency.

[0192] In some embodiments, the negative oxygen water ion generating device 50 includes a control component 800, which includes a main control board, a microcontroller (MCU), a first sub-control component 801, and a second sub-control component 802. The first sub-control component 801 is used to control the rotation of the first sub-drive unit 710, and the second sub-control component 802 is used to control the rotation of the second sub-drive unit 720. By controlling the rotation angles of the first sub-drive unit 710 and the second sub-drive unit 720, the purpose of controlling the rotation direction and angle of the rotating unit 100 is achieved.

[0193] For example, the operation process of the negative oxygen water ion generating device 50 includes:

[0194] The device is turned on.

[0195] The main control board detects whether the current position of the first sub-drive unit 710 and the second sub-drive unit 720 is in the initial position state. If so, it proceeds to the next step. If not, the MCU will send a signal to the first sub-control component 801 and the second sub-control component 802 to adjust the first sub-drive unit 710 and the second sub-drive unit 720 to the initial default state.

[0196] The main control board receives information about the location to which the ions need to be delivered.

[0197] The main control board transmits the position information to the MCU, and the MCU converts the position signal into the rotation signal required by the first sub-driving unit 710 and the second sub-driving unit 720, and issues the command to the first sub-control component 801 and the second sub-control component 802, and the first sub-control component 801 and the second sub-control component 802 control the corresponding motor to rotate the corresponding preset angle. The first sub-driving unit 710 drives the rotating unit 100 to rotate in the horizontal direction, and the second sub-driving unit 720 drives the rotating unit 100 to rotate in the vertical direction.

[0198] Each of the above position information directly corresponds to the rotation angle of the first sub-driving unit 710 and the second sub-driving unit 720 through a logic algorithm until the second air outlet 140 faces the target position to ensure that ions are transported to the target position.

[0199] The control process of the rotating part 100 is simple and efficient. The external input position signal is directly converted into the rotation angle signal of the first sub-driving part 710 and the second sub-driving part 720 through a logic algorithm, and acts on the rotating part 100 at the same time.

[0200] In some embodiments, in order to control the accuracy of position orientation, the number of steps of the stepper motors of the first sub-drive unit 710 and the second sub-drive unit 720 within the rotation angle limit range can be appropriately increased, thereby increasing the matching positions of the horizontal stepper motor and the vertical stepper motor, thereby improving the resolution. For example, the horizontal stepper motor and the vertical stepper motor can be divided into 7 steps within the angle limit range, so there are a total of 49 positions. If the number of steps of the horizontal stepper motor and the vertical stepper motor within the angle limit range is increased to 10 steps, there are a total of 100 positions, and the corresponding position accuracy will be significantly improved. Here, the horizontal stepper motor refers to the first sub-drive unit 710, and the vertical stepper motor refers to the second sub-drive unit 720.

[0201] In some embodiments, the air supply pipe connected to the rotating part 100 is a flexible pipe to adapt to the rotation of the rotating part 100 .

[0202] In some embodiments, reference Fig.25 , the negative oxygen water ion generating device 50 includes one of a directional transport mode or a purge mode.

[0203] In the directional transport mode, the rotating part 100 is kept at a set angle position to directional transport ions. In the directional transport mode, the driving part 700 drives the rotating part 100 to rotate a corresponding angle according to the target position information, so that the second air outlet 140 faces the target position, and the blown ion wind 3 can directly reach the target position.

[0204] In the purge mode, the rotating portion 100 reciprocates within a set plane to transport ions in a purge manner within the set plane.

[0205] The purge mode includes at least one of a horizontal purge mode, a vertical purge mode, or a 3D purge mode.

[0206] In the horizontal sweeping mode, the rotating part 100 reciprocates in a first plane extending in the transverse direction to transport ions in the first plane in a sweeping manner. For example, the first sub-driving part 710 drives the rotating part 100 to reciprocate in the first plane. Fig.12 As shown, the first plane is a horizontal plane, for example, to achieve ion sweeping in the horizontal direction.

[0207] In the vertical sweeping mode, the rotating part 100 reciprocates in the second plane extending in the vertical direction to transport ions in the second plane in a sweeping manner. For example, the second sub-driving part 720 drives the rotating part 100 to reciprocate in the second plane. Fig.13 Taking the second plane as a vertical plane as an example, ion sweeping in the vertical direction is achieved.

[0208] In the 3D sweep mode, the rotating part 100 reciprocates in the first plane and the second plane to transport ions in different directions in the three-dimensional space. For example, the first sub-driving part 710 and the second sub-driving part 720 work simultaneously to drive the rotating part 100 to reciprocate in the first plane and the second plane at the same time. Taking the first plane as a horizontal plane and the second plane as a vertical plane as an example, ions are transported in different directions in the room.

[0209] In some embodiments, the controller 8 is further configured to:

[0210] When the indoor unit 1 is turned on for the first time, the size information of the indoor space 2 where the indoor unit 1 is located and the installation position information of the indoor unit 1 are obtained. The size information of the indoor space 2 includes the size of the indoor space 2, the size of doors and windows, and the position information of doors and windows.

[0211] According to the collected size information of the indoor space 2 where the indoor unit 1 is located and the installation position information of the indoor unit 1, three-dimensional spatial coordinate points are arranged in the indoor space 2 to form a three-dimensional spatial matrix.

[0212] Determine the first rotation angle value A of the first sub-drive unit of the negative oxygen water ion generating device 50 and the second rotation angle value B of the second sub-drive unit corresponding to the three-dimensional coordinate point in the three-dimensional space matrix, and store the correspondence between the three-dimensional coordinate point and the first rotation angle value A and the second rotation angle value B.

[0213] The infrared sensor 4 is turned on to obtain the number of people in the indoor space 2 and the target three-dimensional spatial coordinates of the people in the indoor space 2.

[0214] According to the acquired target three-dimensional spatial coordinates and the correspondence between the stored three-dimensional coordinate points and the first rotation angle value A and the second rotation angle value B, the first rotation angle value and the second rotation angle value are determined, and the first driving unit and the second driving unit are controlled to operate according to the first rotation angle value and the second rotation angle value to blow the ion wind to the target position (i.e., the target three-dimensional spatial coordinates where the indoor personnel are located).

[0215] It is understandable that when the indoor unit 1 is turned on for the first time, the controller 8 obtains the size information of the indoor space 2 where the indoor unit 1 is located and the installation position information of the indoor unit 1 to form a three-dimensional space matrix, and the controller 8 determines the rotation range of the rotating part 100 according to the three-dimensional space matrix.

[0216] For example, the controller 8 converts any one of the at least one three-dimensional coordinate points in the three-dimensional space matrix into a first rotation angle A of the rotating part 100 in the horizontal plane and a second rotation angle B in the vertical plane according to the three-dimensional space matrix and the position of the indoor unit 1, and stores the mapping relationship between any one of the three-dimensional coordinate points and the first rotation angle A and the second rotation angle B.

[0217] Reference Figure 1C When the device is turned on for the first time, the controller 8 obtains information such as the size of the room and the location of the indoor unit 1, and saves this information. Then, the three-dimensional space coordinates are decomposed according to a certain size interval to form a three-dimensional space matrix, and any point of the matrix corresponds to a three-dimensional space coordinate. The controller 8 then converts the three-dimensional space coordinate corresponding to any point into the horizontal and vertical rotation angle values ​​of the rotating part 100 according to the relative position relationship between the three-dimensional space coordinate and the air conditioner, thereby realizing ion transport to any position in the indoor space 2.

[0218] This method calculates and saves the steering angles of the first sub-drive unit 710 and the second sub-drive unit 720 corresponding to each coordinate position in the room in advance, which greatly improves the processing speed of the controller 8 in converting the three-dimensional position information into the motor control signal of the negative oxygen water ion generating device 50 during actual use, and improves the stability of the air conditioner 1000.

[0219] In some embodiments, the infrared sensor 4 is also configured to detect the number of people in the room.

[0220] The controller 8 determines the three-dimensional spatial coordinates of the person based on the detection information of the infrared sensor 4, and retrieves the mapping value to control the rotation position of the rotating part 100, so that the negative oxygen water ion generating device 50 transports ions to the position where the person is located.

[0221] The infrared sensor 4 detects the number of people in the room and the three-dimensional coordinate positions of the people that have been saved in advance, tracks human body movements, and adjusts the rotation position of the rotating part 100, so that negative oxygen ions are directly transported to the vicinity of the human body.

[0222] In some embodiments, reference Figure 1C and Fig.24 When the indoor unit 1 is turned on for the first time, the controller 8 obtains the size information of the room and the location of the indoor unit 1, and saves this information. The controller 8 decomposes the three-dimensional space coordinates according to a certain size interval (for example, 0.3-1m) to form a three-dimensional space matrix that matches the actual room. Any point of the matrix corresponds to a three-dimensional space coordinate.

[0223] The controller 8 converts each coordinate into the steering angle A and B mapping values ​​of the rotating part 100 of the negative oxygen water ion generating device 50 in the horizontal and vertical directions according to the relative position relationship between the three-dimensional coordinates and the indoor unit 1 and saves them. When the local spatial position coordinate exceeds the maximum steering limit of the rotating part 100, the steering angle at this time uses the maximum steering angle and is saved, so that the ion wind 3 can blow to the target area as much as possible.

[0224] Afterwards, when the indoor unit 1 is turned on, the controller 8 turns on the infrared sensor 4 to detect the position of the indoor person and the three-dimensional spatial coordinates of the person.

[0225] The controller 8 retrieves the horizontal and vertical motor rotation angles A and B under the three-dimensional coordinate position conditions that have been stored previously, and controls the first sub-driving unit 710 and the second sub-driving unit 720 to operate in place, thereby quickly and efficiently blowing negative oxygen ions to the fixed coordinate position.

[0226] In some embodiments, reference Fig.26 The working process of the air conditioner 1000 in the "health care mode" includes S301 to S310.

[0227] It can be understood that when the indoor unit 1 is turned on, the air outlet of the air conditioner performs cooling or heating function according to the user's choice. The user chooses to turn on the "health care mode" according to needs. After turning it on, the negative oxygen water ion generating device 50 starts working.

[0228] The user chooses whether to start the oxygen supply function. If the oxygen supply function is turned on, the first sensor 6 first detects the oxygen concentration X at the first air inlet 13 .

[0229] When the oxygen concentration is lower than the first limit value X1, the controller 8 turns on the oxygen generator 5, and high-concentration oxygen flows into the second air duct 110 of the rotating part 100 through the first sub-air duct 410, and is ionized into negative oxygen ions by the emission electrode 300 and then sent into the room air.

[0230] When the oxygen concentration X satisfies X1≤X<X2, it indicates that the oxygen concentration in the room is within a reasonable range. At this time, the oxygen generator 5 maintains the operating state unchanged and continues to supply oxygen to the room.

[0231] When the oxygen concentration X≥X2, it indicates that the oxygen concentration in the room has reached a high value within a reasonable range. At this time, the controller 8 controls to turn off the oxygen concentrator 5. After the oxygen concentrator 5 is turned off, the oxygen concentration in the room will gradually decrease. When it decreases to X1≤X<X2, the oxygen concentrator 5 will still remain in operation. Only when it is lower than the first limit value X1, the controller 8 will turn on the oxygen concentrator 5 again to complete a cycle.

[0232] In some embodiments, reference Fig.26The working process of the air conditioner 1000 in the "health care mode" also includes S311 to S323.

[0233] After the negative oxygen water ion generating device 50 is working, the infrared sensor 4 first determines the number N of people in the current room.

[0234] When N=1, the infrared sensor 4 detects the position of the person in the room, that is, determines the three-dimensional coordinate system (the position of the head) where the person is located, and the controller 8 calculates the rotation angle of the rotating part 100 in the horizontal and vertical directions according to the person's coordinates, so that the ion wind 3 blows around the human body.

[0235] At the same time, the controller 8 calculates the distance D between the person and the first air outlet 11 according to the person's position coordinates detected by the infrared sensor 4. When D≥the preset distance Dt, it means that the person is far away from the first air outlet 11 at this time, and the power provided by the first fan 30 can no longer meet the needs of long-distance ion transmission. At this time, the controller 8 controls to turn on the second fan 500 to provide power for the second air duct 110 of the negative oxygen water ion generating device 50 alone, thereby increasing the blowing speed of the ion wind 3, thereby allowing the negative oxygen ions to be blown to a farther target position.

[0236] When D is less than the preset distance Dt, it indicates that the person is relatively close to the first air outlet 11 and the power provided by the first fan 30 itself has met the requirement of the ion transport distance, so the second fan 500 is turned off at this time.

[0237] At each time interval T2, the infrared sensor 4 detects the position coordinates of the person in the room again, and readjusts the blowing angle of the ion wind 3 and the opening of the second fan 500 according to the latest position.

[0238] When N>1, the controller 8 detects the number of people N and the position coordinates M of each person in the indoor space 2 through the infrared sensor 4, and automatically calculates the distance D1, D2, D3, ... DN of each person from the first air outlet 11.

[0239] The controller 8 automatically arranges the personnel positions in order from near to far according to the distance, and then controls the rotation angle of the rotating part 100 in the horizontal and vertical directions, and controls the ion wind 3 to blow from the personnel position closest to the position farthest away. The blowing time for each position is t3, until each personnel position is blown.

[0240] During the purging process, the controller 8 determines the distance D between the person and the first air outlet 11, and when D≥preset distance Dt, the second fan 500 is turned on, and after one cycle is completed, the second fan 500 is turned off.

[0241] After the first purge is completed, the controller 8 controls the infrared sensor 4 to immediately reconfirm the position coordinates of the people in the indoor space 2, and rearrange the distance between each person and the first air outlet 11: D1, D2, D3...DN.

[0242] According to the latest arrangement order, the controller 8 controls the negative oxygen water ion generating device 50 to purge again and starts the second fan 500 in a timely manner.

[0243] It should be noted that since negative ion devices have the function of dust reduction, during the use of negative ion devices, some of the dust that settles adheres to the wall, which may make the wall around the negative ion device black, thus causing the "black wall phenomenon". It is understandable that the higher the concentration of negative ions produced by the negative ion device, the stronger the purification ability, and the more obvious the "black wall phenomenon".

[0244] It is understandable that the negative oxygen water ion generating device 50 releases negative oxygen ions and nano water ions into the air. At the position close to the emission tip of the emission electrode 300, the concentration of negative oxygen ions is high, and some negative oxygen ions are easily attached to the surface of the wall or shell around the emission electrode 300, thereby causing some dust in the adsorbed air to adhere to the wall or shell, and produce a "black wall phenomenon". In addition, some particles are negatively charged by combining with negative oxygen ions. Under the action of the electric field force, the negatively charged particles will move toward the grounded object and eventually deposit on the surface of the grounded object. Over time, the continuous deposition of particles will produce a "black wall phenomenon" around the emission electrode 300.

[0245] In some embodiments, reference Figure 2A The housing 10 of the air conditioner 1000 includes a housing body 101 and a front side plate 102. The front side plate 102 is disposed on a side (ie, the front side) of the housing body 101 close to a user. The first air outlet 11 is disposed on the front side plate 102.

[0246] In some embodiments, the housing 10 further includes a panel 40, which is disposed on one side of the front side plate 102. The negative oxygen water ion generating device 50 is disposed on the panel 40. For example, the panel 40 is a plastic part.

[0247] In some embodiments, reference Fig. 22 The panel 40 includes a panel body 43 and an opening 41, the opening 41 is provided on the panel body 43, and one end of the negative oxygen water ion generating device 50 extends out of the opening 41. The opening 41 is connected to the second air outlet 140 of the rotating part 100, and the emitting electrode 300 extends through the second air outlet 140 and the opening 41, so that the ions released by the emitting electrode 300 flow into the indoor space 2 without obstruction, which is convenient for the escape and diffusion of the ions.

[0248] It should be noted that the panel 40 and the front side panel 102 can be a split structure, which facilitates the assembly of the panel 40 and the negative oxygen water ion generating device 50. The panel 40 and the front side panel 102 can also be an integrally formed part, which is conducive to simplifying the installation steps and thus improving the installation efficiency.

[0249] In some embodiments, the panel 40 further includes an escape portion 44, which is disposed at a circumferential edge of the panel body 43 close to the opening 41. For example, the escape portion 44 is a conical surface.

[0250] In some embodiments, the avoidance portion 44 extends toward the shell body 101 (i.e., from front to back), which can prevent the one end of the negative oxygen water ion generating device 50 from extending out of the panel body 43, thereby protecting the negative oxygen water ion generating device 50 and preventing the negative oxygen water ion generating device 50 from being damaged by collision.

[0251] In some embodiments, the inner diameter of the avoidance portion 44 decreases in the direction toward the shell body 101 , so that the avoidance portion 44 can make way for the rotation of the rotating portion 100 , avoiding obstruction to the diffusion of ions and facilitating the escape and diffusion of ions.

[0252] It should be noted that although the panel 40 is not directly grounded, when the air humidity is high or the air conditioner 1000 is in cooling mode, causing condensation on the surface of the panel 40, since the panel 40 is in close contact with the grounding sheet metal of the air conditioner, the panel 40 is also equivalent to a weak ground end. Therefore, after long-term use, a "black wall phenomenon" will appear on the panel 40, causing the panel 40 to become dirty.

[0253] In some embodiments of the present disclosure, the panel 40 includes metal conductive particles, and the negative high-voltage power supply 600 supplies negative electricity to the panel 40, so that the panel 40 is negatively charged. On the one hand, the negative oxygen ions generated by the negative oxygen water ion generating device 50 are repelled by the panel 40 and move away from the panel 40, thereby inhibiting the negative ions from attaching to the panel 40 and avoiding the "black wall phenomenon". On the other hand, the negatively charged particles in the air that are combined with the negative oxygen ions are repelled by the panel 40 and move away from the panel 40, thereby avoiding the deposition of the negatively charged particles on the panel 40 and avoiding the "black wall phenomenon" on the panel 40.

[0254] It should be noted that the panel 40 is a plastic part. Metal conductive particles are added to the plastic particles of the panel 40 which are injection-molded to increase the conductivity of the panel 40 without affecting the color of the panel 40 .

[0255] In some embodiments, the negative high-voltage power supply 600 provides negative high voltage to the panel 40, so that a large amount of negative charges are distributed on the panel 40. When negatively charged particles in the air approach the panel 40, they are repelled by the panel 40, which is also negatively charged, and move away from the panel 40, so that the negatively charged particles are deposited on the panel 40.

[0256] Reference Fig.21 The negative high voltage power supply 600 includes a first negative high voltage power supply line 610 and a second negative high voltage power supply line 620. The first negative high voltage power supply line 610 is configured to supply power to a negative ion generating device (eg, a negative oxygen water ion generating device 50). The second negative high voltage power supply line 620 is configured to supply power to the panel 40.

[0257] For example, the negative high voltage provided by the first negative high voltage power supply line 610 ranges from -3000V to -6000V. The negative high voltage provided by the second negative high voltage power supply line 620 ranges from -500V to -2000V.

[0258] In some embodiments, a protective resistor is set at the high-voltage output end of the negative high-voltage power supply 600, and the design power of the negative oxygen water ion generating device 50 is relatively small, only 1w. When a person accidentally touches the transmitting electrode 300 or the panel 40, the current flowing through the human body is in the microampere level, so it will not cause adverse effects on the human body.

[0259] In some embodiments, a terminal post 42 is disposed on the panel 40 , and the second negative high-voltage power supply line is connected to the terminal post 42 to supply negative power to the panel 40 .

[0260] In some embodiments, reference Figure 2A and Figure 2B The indoor unit 1 further includes a second sensor 7 (such as a distance sensor), which is configured to detect the distance between the person and the panel 40. When the distance between the person and the panel 40 is less than a set value, the negative high-voltage power supply 600 stops supplying power.

[0261] It should be noted that since both the negative oxygen water ion generating device 50 and the panel 40 are charged, although the electric charge of the negative oxygen water ion generating device 50 and the panel 40 will not cause harm to the human body, there will still be a slight instantaneous electric shock when people touch them.

[0262] In some embodiments, the air conditioner 1000 includes a debugging button, which is disposed on the housing 10. For example, the debugging button is disposed on the panel 40. The air conditioner 1000 also includes a "debugging mode", referring to Fig. 27 , the operation process of the "debugging mode" of the air conditioner 1000 includes S401 to S404.

[0263] It is understandable that after the debugging button is turned on, the air conditioner 1000 is turned on to the "debugging mode". In the "debugging mode", after the debugger chooses to turn on the purification function, the negative oxygen water ion generating device 50 and the panel 40 are immediately powered on to facilitate the debugger to check the operating status of the air conditioner 1000.

[0264] Reference Fig. 27 When debugging is completed and the “debugging mode” is turned off, the controller 8 is further configured to execute S405 to S407.

[0265] It can be understood that after debugging is completed, when the indoor unit 1 is in use, the distance between the person and the panel 40 is detected by the second sensor 7. When the distance between the person and the panel 40 is less than the set value (for example, 1m), the negative high-voltage power supply 600 stops supplying power, that is, the negative oxygen water ion generating device 50 and the panel 40 are powered off, thereby avoiding the user from feeling uncomfortable with electric shock when touching the emitting electrode 300 or the panel 40.

[0266] If it is determined that the distance between the person and the panel 40 is greater than the set value, the negative high voltage power supply 600 supplies power to the negative oxygen water ion generating device 50 and the panel 40 again.

[0267] Some embodiments of the present disclosure also provide a control method for an air conditioner 1000 , which can be executed by the controller 8 or the air conditioner 1000 .

[0268] In some embodiments, reference Fig.24 , the method includes S101 to S105.
