[0042] Some embodiments of the present disclosure will be described clearly and completely below with reference to the accompanying drawings, of which it is apparent that the described embodiments are only a part of the embodiments of the present disclosure, but not all the embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present disclosure.

[0043] Unless the context clearly requires otherwise, throughout the description and the claims, the term "comprise," and variations thereof (e.g., "comprises" and "comprising"), will be construed to be inclusive in a manner consistent with the term's plain meaning, namely, "including but not limited to." In describing the description, the terms "one embodiment," "some embodiments," "exemplary embodiments," "example," "specific example" or "some examples," and the like, mean that a particular feature, structure, material, or characteristic is included in at least one embodiment or example of the disclosure, but that it can not be included in other embodiments or examples. The illustrative appearance of the foregoing terms in various places in the description are not necessarily intended to refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics can be combined in any suitable manner in one or more embodiments or examples.

[0044] Hereinafter, the terms "first", "second", etc. are used only for the purpose of description and should not be construed as indicating or implying relative importance or implying the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the embodiments of the disclosure, the meaning of "a plurality of" is two or more, unless otherwise specified.

[0045] In describing some embodiments, "coupled" and "connected," and variations thereof, can be used. The term "connected" should be interpreted broadly, for example, "connected" can be fixedly connected, or detachably connected, or integrated; can be directly connected, or connected through an intermediate medium. The term "coupled" indicates that two or more components have direct physical contact or electrical contact. The term "coupled" or "communicatively coupled" can also mean that two or more components do not have direct contact with each other, but still cooperate or interact with each other. The embodiments disclosed herein are not necessarily limited to the content herein.

[0046] "A, B, and C at least one of" has the same meaning as "at least one of A, B, or C", and includes the following combinations of A, B, and C: only A, only B, only C, a combination of A and B, a combination of A and C, a combination of B and C, and a combination of A, B, and C.

[0047] "A and / or B" includes the following three combinations: only A, only B, and a combination of A and B.

[0048] The use of “adapted to” or “configured to” herein means open and inclusive language that does not exclude devices adapted to or configured to perform additional tasks or steps.

[0049] As used herein, “about,” “approximately” or “around” includes the recited value and the average value within an acceptable range of deviation from the particular value, as determined by one of ordinary skill in the art considering the measurement in question and the error in measuring the particular quantity (i.e., the limitations of the measurement system).

[0050] As used herein, “parallel,” “perpendicular,” “equal” includes the recited condition and conditions that approximate the recited condition, the approximation being within an acceptable range of deviation, as determined by one of ordinary skill in the art considering the measurement in question and the error in measuring the particular quantity (i.e., the limitations of the measurement system). For example, “parallel” includes absolute parallel and near parallel, where near parallel can have an acceptable range of deviation of, for example, within 5°; “perpendicular” includes absolute perpendicular and near perpendicular, where near perpendicular can also have an acceptable range of deviation of, for example, within 5°. “Equal” includes absolute equality and near equality, where near equality can have an acceptable range of deviation of, for example, a difference between the two that is less than or equal to 5% of either.

[0051] In the related art, a negative oxygen water ion generating device generates negative oxygen ions by ionizing air. However, since the oxygen content in air is only 21%, only about 1 / 5 of the air can be used to generate negative oxygen ions (negative oxygen ions are a gaseous negative ion) in the ionization process, and the rest of the air generates negative ions other than negative oxygen ions. As such, the negative oxygen water ion generating device generates negative oxygen ions at a low concentration, reducing the sterilization effect of negative oxygen ions.

[0052] In addition, negative ions have a short lifespan. After being generated, if the negative ions cannot reach the surroundings of personnel activities in time, they will gradually disappear. Therefore, negative ions need to be delivered to the location where personnel are located in time.

[0053] The negative oxygen water ion generating device in the related art is usually arranged at the air outlet of an indoor unit. The flow of air conditioner air at the air outlet of the indoor unit can easily interfere with the movement of ion air. For example, some air conditioners also include a “wind avoids people” mode to avoid blowing air conditioner air to the location where the human body is located, in order to ensure the comfort of air conditioner air. In the “wind avoids people” mode, it is more difficult for negative ions to be delivered to the surroundings of the human body. As a result, a large amount of negative ions will be transmitted to the ineffective area outside the location where personnel are located, which is easy to cause waste of negative oxygen water ions, thereby reducing the air purification effect.

[0054] In addition, in the related art, the negative oxygen water ion generating device is fixedly installed, and the ion delivery direction cannot be adjusted, so that the negative oxygen water ion generating device in the related art cannot achieve the effect of blowing the ion wind toward the position of the person.

[0055] To solve the above problems, the air conditioner provided by some embodiments of the present disclosure provides oxygen to the negative oxygen water ion generating device by arranging 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 improving the concentration of negative oxygen ions generated by the negative oxygen water ion generating device, and improving the sterilization effect of the air conditioner.

[0056] The air conditioning device refers to a device capable of adjusting air. The functions of the air conditioning device include cooling or heating air, sterilizing and purifying air, and increasing oxygen concentration. Common air conditioning devices include air conditioners, purifiers, and the like.

[0057] Hereinafter, the arrangement of the negative oxygen water ion generating device in the air conditioning device will be described mainly by taking an air conditioner as an example.

[0058] As shown in FIGS. 1A and 1B, some embodiments of the present disclosure provide an air conditioner 1000. The air conditioner 1000 includes an outdoor unit 20.

[0059] In some embodiments, the outdoor unit 20 includes a compressor 201 configured to compress refrigerant to form high-pressure refrigerant by compressing low-pressure refrigerant.

[0060] In some embodiments, the outdoor unit 20 further includes a second heat exchanger 203 (outdoor heat exchanger) configured to exchange heat between outdoor air and refrigerant transmitted in the second heat exchanger 203. For example, the second 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 is condensed by emitting heat to the outdoor air through the second heat exchanger 203. The second heat exchanger 203 works as an evaporator in the heating mode of the air conditioner 1000, so that the refrigerant after pressure reduction is evaporated by absorbing heat of the outdoor air through the second heat exchanger 203.

[0061] In some embodiments, the second heat exchanger 203 includes heat exchange fins to expand the contact area between the outdoor air and the refrigerant transmitted in the second heat exchanger 203, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0062] In some embodiments, the outdoor unit 20 further comprises a third fan 204 (outdoor fan) configured to draw outdoor air into the outdoor unit 20 through an outdoor air inlet of the outdoor unit 20 and send the outdoor air, which has been heat-exchanged with the second heat exchanger 203, out of the outdoor unit 20 through an outdoor air outlet of the outdoor unit 20. The third fan 204 provides power for the flow of the outdoor air.

[0063] In some embodiments, the air conditioner 1000 further comprises an indoor unit 1, which can be connected to the outdoor unit 20 through the pipeline 70 to transmit the refrigerant.

[0064] In some embodiments, the indoor unit 1 comprises a first heat exchanger 60 (indoor heat exchanger). The first heat exchanger 60 is configured to exchange heat between indoor air and the refrigerant transmitted in the first heat exchanger 60. For example, the first heat exchanger 60 works as an evaporator in the cooling mode of the air conditioner 1000, so that the refrigerant, which has been heat-exchanged with the second heat exchanger 203, is evaporated by absorbing heat from the indoor air through the first heat exchanger 60. The first heat exchanger 60 works as a condenser in the heating mode of the air conditioner 1000, so that the refrigerant, which has been heat-exchanged with the second heat exchanger 203, is condensed by releasing heat to the indoor air through the first heat exchanger 60.

[0065] In some embodiments, the first heat exchanger 60 comprises heat exchange fins to expand the contact area between the indoor air and the refrigerant transmitted in the first heat exchanger 60, thereby improving the heat exchange efficiency between the indoor air and the refrigerant.

[0066] As shown in FIGS. 1A and 1B, the indoor unit 1 further comprises a first fan 30 configured to draw indoor air into the indoor unit 1 through a first air inlet 13 of the indoor unit 1 and send the indoor air, which has been heat-exchanged with the first heat exchanger 60, out of the indoor unit 1 through a first air outlet 11 of the indoor unit 1. The first fan 30 provides power for the flow of the indoor air.

[0067] In some embodiments, the outdoor unit 20 further comprises an expansion valve 205 connected between the second heat exchanger 203 and the first heat exchanger 60. The opening degree of the expansion valve 205 adjusts the pressure of the refrigerant flowing through the second heat exchanger 203 and the first heat exchanger 60, so as to adjust the flow rate of the refrigerant flowing between the second heat exchanger 203 and the first heat exchanger 60. The flow rate and the pressure of the refrigerant flowing between the second heat exchanger 203 and the first heat exchanger 60 will affect the heat exchange performance of the second heat exchanger 203 and the first heat exchanger 60. The expansion valve 205 can be an electronic valve. The opening degree of the expansion valve 205 is adjustable to control the flow rate and the pressure of the refrigerant flowing through the expansion valve 205.

[0068] In some embodiments, the compressor 201, the second heat exchanger 203, the expansion valve 205 and the first heat exchanger 60 connected in sequence form a refrigerant circuit in which refrigerant circulates, and the refrigerant exchanges heat with air through the second heat exchanger 203 and the first heat exchanger 60 respectively to realize the cooling mode or the heating mode of the air conditioner 1000. The four-way valve 202 is connected in the refrigerant circuit, and the four-way valve 202 is configured to switch the flow direction of the refrigerant in the refrigerant circuit to make the air conditioner 1000 execute the cooling mode or the heating mode.

[0069] In some embodiments, referring to FIG. 2A, the indoor unit 1 further includes a housing 10 including a receiving cavity to accommodate the first heat exchanger 60, the first fan 30 and the like.

[0070] In some embodiments, the indoor unit 1 further includes a first air outlet 11. For example, the first air outlet 11 is arranged on the side (e.g., the front side) of the housing 10 facing the user.

[0071] In some embodiments, the indoor unit 1 further includes a first air inlet 13. For example, the first air inlet 13 is arranged on the side (e.g., the rear side) of the housing 10 opposite to the side on which the first air outlet 11 is arranged.

[0072] Under the action of the first fan 30, indoor air flows to the first heat exchanger 60 through the first air inlet 13, and after being cooled or heated by the first heat exchanger 60, the indoor air flows out of the first air outlet 11, so as to realize the adjustment of the temperature of the indoor air.

[0073] In some embodiments, the indoor unit 1 further includes a deflector 12 arranged at the first air outlet 11. The air conditioner 1000 adjusts the flow direction of the air conditioner air blown out of the first air outlet 11 through the deflector 12.

[0074] In some embodiments, the air conditioner 1000 includes a cooling mode. In the cooling mode, the first air outlet 11 is opened, and the air conditioner 1000 cools the indoor air to reduce the temperature of the indoor environment.

[0075] In some embodiments, the air conditioner 1000 further includes a heating mode. In the heating mode, the first air outlet 11 is opened, and the air conditioner 1000 heats the indoor air to increase the temperature of the indoor environment.

[0076] It should be noted that the air blown out of the first air outlet 11 in some embodiments of the present disclosure is referred to as air conditioner air. For example, the air conditioner air includes cool air generated by the air conditioner 1000 in the cooling mode, and hot air generated by the air conditioner 1000 in the heating mode, and the like.

[0077] In some embodiments, referring to FIG. 3, the indoor unit 1 further comprises a third channel 14, which is in communication with the first air inlet 13 and the first air outlet 11. After the indoor air enters the indoor unit 1 through the first air inlet 13, the indoor air enters the indoor space 2 through the third channel 14 and the first air outlet 11. The third channel 14 is a flow channel for the air-conditioning air.

[0078] In some embodiments, the air conditioner 1000 further comprises a negative ion generating device, which is arranged in the indoor unit 1. The negative ion generating device is configured to release negative ions into the indoor space 2.

[0079] Since most particulate matters in the air are positively charged, the negative ions can combine with the positively charged particles such as bacteria, dust, and smoke in the air to make the particles negatively charged. The negatively charged particles are attracted to the positively charged particles and agglomerate and fall, thereby achieving the purpose of air purification. In addition, some particulate matters combine with negative oxygen ions to become negatively charged. Under the action of the electric field force, the negatively charged particulate matters move towards grounded objects and eventually deposit on the surfaces of the grounded objects, thereby achieving the effect of purifying the air.

[0080] In some embodiments, the negative ion generating device is arranged at the first air outlet 11, and the negative ions are blown into the indoor space 2 along with the air-conditioning air.

[0081] In some embodiments, the negative ion generating device is arranged between the first air outlet 11 and the gas flow path (i.e., the third channel 14) between the first air inlet 13, and the negative ions enter the indoor space 2 along with the airflow in the third channel 14.

[0082] In some embodiments, the negative ion generating device is a negative oxygen water ion generating device 50, which is configured to release negative oxygen ions and nano water ions into the indoor space 2.

[0083] Negative oxygen ions have a significant purifying effect on particulate matters and also have effects such as promoting blood circulation in the body and inhibiting the development of diseases. The main component of nano water ions includes hydroxyl radicals, which have sterilization and disinfection effects.

[0084] It should be noted that in some embodiments below, the ions can include negative oxygen ions, nano water ions generated by the negative oxygen water ion generating device 50 in the ionization process, and negative ions other than negative oxygen ions and nano water ions that can have a purifying effect.

[0085] In some embodiments, the air conditioner 1000 further comprises a health care mode. In the health care mode, the air conditioner 1000 has a purifying function. When the purifying function of 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.

[0086] In some embodiments, the negative oxygen water ion generating device 50 is arranged beside the first air outlet 11, that is, the negative oxygen water ion generating device 50 is not arranged in the first air outlet 11. In this way, the air conditioner 1000 can independently adjust the directions of the air conditioner air blown out from the first air outlet 11 and the ion air 3 blown out from the negative oxygen water ion generating device 50, that is, independently control the air conditioner air and the ion air 3, so that the air outlet directions of the air conditioner air and the ion air 3 do not interfere with each other.

[0087] In this way, on the one hand, the air conditioner 1000 can avoid the air conditioner air from directly blowing on a person by adjusting the air deflector 12, thereby improving the comfort of the air conditioner air. On the other hand, the air conditioner 1000 can make the ion air 3 blow to the vicinity of the person by adjusting the air outlet angle of the negative oxygen water ion generating device 50, thereby improving the health and wellness effect of the negative oxygen ions on the human body.

[0088] In addition, in some embodiments, the negative oxygen water ion generating device 50 can be independently operated when the first air outlet 11 of the indoor unit 1 is closed. For example, when the indoor temperature is appropriate, it is not necessary to start the cooling mode or the heating mode of the indoor unit 1 to adjust the temperature of the indoor air. At this time, the first air outlet 11 can be closed, and the negative oxygen water ion generating device 50 can be independently started to provide the indoor space 2 with nano water ions and negative oxygen ions to improve the indoor air quality.

[0089] In some embodiments, referring to FIG. 3, the indoor unit 1 further includes a first channel 400 (air supply duct) configured to provide air for ionization to the negative oxygen water ion generating device 50. It should be noted that the first channel 400 and the third channel 14 (i.e., the flow channel of the air conditioner air) can be independently configured.

[0090] In this way, by independently arranging the first channel 400 and the third channel 14, the negative oxygen water ion generating device 50 can still be started when the indoor unit 1 is closed, so as to deliver nano water ions and negative oxygen ions to the indoor space 2, thereby enriching the application scenarios of the negative oxygen water ion generating device 50.

[0091] In some embodiments, referring to FIGS. 3 and 4, the air inlet of the first channel 400 is located on the air inlet side of the first heat exchanger 60, that is, the air inlet of the first channel 400 communicates with the first air inlet 13. In this way, the air entering the first channel 400 is air that has not been heat-exchanged by the first heat exchanger 60, thereby being able to reduce the influence of the temperature change of the air on the ionization effect of the negative oxygen water ion generating device 50.

[0092] In some embodiments, referring to FIGS. 7-14D, the negative oxygen water ion generator 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 first heat exchanger 60 can be supplied to the emitting electrode 300 of the negative oxygen water ion generator 50 via the first channel 400.

[0093] Referring to FIG. 23, the emitting electrode 300 can be made of a carbon fiber porous rod material containing a strong water absorption factor, which can absorb moisture from the air. Under high voltage conditions, the material can ionize water into nano water ions and oxygen into negative oxygen ions.

[0094] For example, the emitting electrode 300 includes a water absorption factor and a carbon fiber bundle. The carbon fiber bundle is carbonized at high temperature after epoxy curing to form a porous carbon fiber rod structure, and one end is processed into a hemispherical emitting tip by mechanical processing. After processing, the water absorption factor is immersed into the carbon fiber bundle by ultrasonic infiltration method to make a high-efficiency water absorption electrode.

[0095] In some embodiments, referring to FIG. 11, the negative oxygen water ion generator 50 further includes a negative high-voltage power supply 600 configured to provide a negative high voltage to the emitting electrode 300 to ionize air and water.

[0096] In some embodiments, referring to FIG. 5, the indoor unit 1 further includes a second fan 500 (auxiliary fan). The second fan 500 is arranged in the first channel 400, and the second fan 500 is configured to provide gas flow power in the first channel 400 to improve the delivery distance of the ion wind 3.

[0097] In some embodiments, referring to FIG. 2B, the indoor unit 1 further includes a second sensor 4 (infrared sensor) configured to detect the position of the indoor personnel.

[0098] In some embodiments, the indoor unit 1 further comprises a controller 8, which can be a chip or a processor. For example, the processor can be a general central processing unit (CPU), a microprocessor, an application specific integrated circuit (ASIC). Alternatively, the controller 8 can 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 can be an integrated circuit (IC).

[0099] In some embodiments, the controller 8 is coupled with the second sensor 4 and the second fan 500. The controller 8 is configured to acquire position information of the person in the indoor space 2.

[0100] The distance D of the person from the first air outlet 11 is determined according to the acquired position information. It should be noted that, since the first air outlet 11 and the negative oxygen water ion generating device 50 are arranged on the front side of the indoor unit 1, the distance D here can be the distance of the person from the first air outlet 11 of the air conditioner wind, or the distance of the person from the second air outlet 140 of the ion wind.

[0101] The second fan 500 is selectively started according to the size relationship between D and the first preset distance Dt, so that the ion wind 3 blown by the negative oxygen water ion generating device 50 can reach the position where the person is located.

[0102] If it is determined that the distance D of the person from the first air outlet 11 is ≥ the first preset distance Dt, the second fan 500 is started. That is, in the case that the person is far from the first air outlet 11, the second fan 500 is started to improve the delivery distance of the ion wind 3 and ensure that the ion wind 3 can be delivered to the person.

[0103] If it is determined that the distance D of the person from the first air outlet 11 is < the first preset distance Dt, the second fan 500 is turned off. That is, in the case that the person is close to the first air outlet 11, the second fan 500 is turned off. At this time, the indoor unit 1 is made to generate a positive pressure by the power of the first fan 30, so that an airflow is also generated in the first channel 400, and the ion wind 3 is delivered to the person under the action of the airflow.

[0104] In some embodiments, the second fan 500 is a variable frequency fan. Since the rotating speed of the variable frequency fan is adjustable, the accuracy of the control of the transmission distance of the ion wind 3 can be improved.

[0105] In some embodiments, the controller 8 is further configured to:

[0106] obtain the spatial position coordinates of the personnel detected by the second sensor 4 in the indoor space 2, and calculate the distance D of the personnel from the first air outlet 11 according to the spatial position coordinates.

[0107] According to the distance D, the operating frequency of the second fan 500 is adjusted. It should be noted that 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.

[0108] The air conditioner 1000 in some embodiments of the present disclosure adjusts the start-stop and rotating frequency of the second fan 500 according to the distance D of the personnel from the first air outlet 11. In this way, not only can the ion wind 3 be blown around the human body, but also the air volume and air speed of the ion wind 3 can be within the preset range, improving the comfort of the user.

[0109] In some embodiments, referring to FIGS. 2B, 5 and 6, the outdoor unit 1 further comprises an oxygen generator 5 configured to provide oxygen to at least one of the first channel 400 or the indoor space 2.

[0110] In this way, by providing oxygen to the first channel 400 through the oxygen generator 5, the oxygen concentration in the air ionized by the negative oxygen ion generator 50 is improved, thereby the concentration of negative oxygen ions generated by the negative oxygen ion generator 50 can be improved to improve the health care effect on the human body.

[0111] In some embodiments, in the “health care mode”, the air conditioner 1000 also has an oxygen supply function. When the oxygen supply function of the health care mode is turned on, the oxygen generator 5 is turned on to provide oxygen to the first channel 400 to improve the concentration of negative oxygen ions ionized by the negative oxygen ion generator 50.

[0112] In some embodiments, in the health care mode, the purification function and the oxygen supply function of the air conditioner 1000 can be turned on at the same time. For example, the indoor unit 1 is turned on, and the air conditioner 1000 performs the cooling or heating mode according to the user's selection. Then, the user selects whether to turn on the “health care mode” according to the demand. After the user turns on the “health care mode”, the negative oxygen ion generator 50 is turned on to work and purify the air. In the “health care mode”, the user selects whether to start the oxygen supply function according to the demand. If the user selects to turn on the oxygen supply function, the oxygen generator 5 is turned on to generate oxygen and supply it to the first channel 400.

[0113] Of course, in some embodiments, the oxygen generator 5 can be turned on alone. At this time, the emission electrode 300 is powered off, the negative oxygen ion generating device 50 stops ionizing air and water, and the oxygen generated by the oxygen generator 5 is delivered to the indoor space 2 to increase the oxygen in the indoor space 2.

[0114] In some embodiments, the oxygen generator 5 is selectively turned on according to the oxygen concentration in the room.

[0115] In some embodiments, the indoor unit 1 further comprises a first sensor 6. For example, the first sensor 6 is an oxygen concentration sensor. The first sensor 6 is arranged at the first air inlet 13 and is configured to detect the oxygen concentration X at the first air inlet 13.

[0116] In some embodiments, the controller 8 is coupled with the first sensor 6 and the oxygen generator 5, and the controller 8 is further configured to:

[0117] Obtain the oxygen concentration X at the first air inlet 13 detected by the first sensor 6.

[0118] If it is determined that the oxygen concentration X < the first limit value X1, it means that the oxygen concentration in the indoor space 2 is low, and at this time the oxygen generator 5 is turned on to increase the oxygen concentration in the air. The oxygen generated by the oxygen generator 5 flows to the emission electrode 300 of the negative oxygen ion generating device 50 through the first channel 400 to increase the concentration of negative oxygen ions generated by ionization.

[0119] If it is determined that the oxygen concentration X is between the first limit value X1 and the second limit value X2, i.e. X satisfies: X1≤X < X2, it means that the oxygen concentration in the indoor space 2 is within a reasonable range, and at this time the oxygen generator 5 maintains the running state and continues to supply oxygen to the indoor space 2.

[0120] If it is determined that the oxygen concentration X ≥ the second limit value X2, it means that the oxygen concentration in the indoor space 2 is high, and at this time the oxygen generator 5 is turned off. After that, the oxygen concentration in the indoor space 2 will decrease. If it is determined that the oxygen concentration in the indoor space 2 decreases to X1≤X < X2, the oxygen generator 5 still remains in the stopped state at this time. If it is determined that the oxygen concentration in the indoor space 2 decreases to < the first limit value X1, the oxygen generator 5 is turned on again. At this time, one oxygen generation cycle is completed.

[0121] In some embodiments, referring to FIG. 5, the first channel 400 comprises a first sub-channel 410, and the air inlet of the first sub-channel 410 is located at the air inlet side of the first heat exchanger 60. The air that has not been heat-exchanged by the first heat exchanger 60 is supplied to the emission electrode 300 of the negative oxygen ion generating device 50 through the first sub-channel 410.

[0122] It can be understood that the first sub-channel 410 is independent of the third channel 14. In this way, independent control of the air conditioner wind and the ion wind 3 can be realized respectively.

[0123] In some embodiments, the second fan 500 is arranged at the air inlet of the first sub-channel 410. When the second fan 500 is turned on, the gas flow rate in the first sub-channel 410 can be increased, so as to increase the delivery distance of the ions generated by the negative oxygen water ion generator 50.

[0124] In some embodiments, the first channel 400 further comprises a second sub-channel 420, which is in communication with the oxygen outlet of the oxygen generator 5 through a pipeline. The air conditioner 1000 provides oxygen into the second sub-channel 420 through the oxygen generator 5, so as to increase the oxygen concentration around the emitting electrode 300 of the negative oxygen water ion generator 50, thereby increasing the concentration of the negative oxygen ions generated in the ionization process, and further helping to improve the oxygen therapy effect on the human body.

[0125] In some embodiments, the negative oxygen water ion generator 50 is movably connected to the shell 10. The controller 8 is further configured to adjust the rotation angle of the negative oxygen water ion generator 50 according to the three-dimensional coordinate value of the position where the person is located, so as to make the ion wind 3 blow towards the human body.

[0126] Referring to FIG. 7, the negative oxygen water ion generator 50 further comprises a rotating part 100, which is configured to adjust the ion delivery direction. The emitting electrode 300 can be arranged 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 the horizontal direction, so as to drive the emitting electrode 300 to rotate in the first plane, and adjust the delivery direction of the ions in the first plane. For example, the first plane can be the horizontal plane where the C-C line shown in FIG. 9 is located.

[0128] In some embodiments, the rotating part 100 is configured to rotate in a second plane extending in the vertical direction, so as to drive the emitting electrode 300 to rotate in the second plane, and adjust the delivery direction of the ions in the second plane. For example, the second plane can be the vertical plane where the B-B line shown in FIG. 9 is located.

[0129] In some embodiments, the rotating part 100 is configured to rotate in the first plane and the second plane at the same time, the first plane extending in the horizontal direction, and the second plane extending in the vertical direction, so as to adjust the delivery direction of the ions in the three-dimensional space.

[0130] It can be understood that when the rotating part 100 rotates in the first plane (i.e. the horizontal plane), the emitting electrode 300 is driven to rotate in the horizontal plane, so as to realize the delivery adjustment of the ions in different directions in the horizontal plane. Referring to FIG. 12, the maximum rotatable angle of the rotating part 100 in the horizontal plane is a°.

[0131] It can be understood that when the rotating part 100 rotates in the second plane (i.e. the vertical plane), the emitting electrode 300 is driven to rotate in the vertical plane, so as to realize the adjustment of the ion transport in different directions in the vertical plane. Referring to FIG. 13, the maximum rotatable angle of the rotating part 100 in the vertical plane is b°.

[0132] In some embodiments, referring to FIGS. 9 and 10, the second channel 110 (air duct) is formed in the rotating part 100. The second channel 110 includes a second air inlet 150, and the second air inlet 150 of the second channel 110 is connected with the air outlet of the first channel 400. The emitting electrode 300 is arranged in the second channel 110. In this way, the gas provided by the first channel 400 can flow into the second channel 110 and contact the emitting electrode 300. In this way, the emitting electrode 300 can maximize the ionization of air and improve the ionization effect.

[0133] In some embodiments, referring to FIGS. 10, 11, 15 and 16, the negative oxygen water ion generating device 50 further includes an electrode mounting seat 130. The electrode mounting seat 130 is arranged in the second channel 110 of the rotating part 100, and the emitting electrode 300 is arranged in the electrode mounting seat 130.

[0134] In some embodiments, the outer wall of the electrode mounting seat 130 is arranged in a spaced manner with the inner wall of the rotating part 100, so as to leave a gap for the flow of gas, so that the gas in the second channel 110 can wrap the emitting tip.

[0135] In some embodiments, the negative oxygen water ion generating device 50 further includes a plurality of connecting pieces 120 (connecting ribs), and the electrode mounting seat 130 is connected with the inner wall of the rotating part 100 through the plurality of connecting pieces 120, so as to realize the mounting of the electrode mounting seat 130 in the second channel 110.

[0136] In some embodiments, the second channel 110 further includes a second air outlet 140, and the second air outlet 140 is arranged on the side (e.g. the front side) of the rotating part 100 facing the user. The ions generated by the emitting electrode 300 flow out from the second air outlet 140.

[0137] In some embodiments, the emitting tip of the emitting electrode 300 extends out through the second air outlet 140. In this way, the ion diffusion and escape are facilitated.

[0138] In some embodiments, the gas entering the second channel 110 from the second air inlet 150 flows from the outer circumferential side of the electrode mounting seat 130 to the second air outlet 140. In this way, the gas in the second channel 110 can wrap the emitting tip of the emitting electrode 300, so as to ensure the contact area of the emitting tip with air, so as to improve the ionization effect.

[0139] It should be noted that since the emitting electrode 300 is arranged in the second channel 110, the gas flow rate in the second channel 110 will affect the ion delivery speed and the delivery distance.

[0140] In some embodiments, the second fan 500 is further configured to adjust the gas flow rate in the second channel 110. In this way, the air conditioner 1000 can control the ion delivery distance by using the second fan 500 to control the gas flow rate in the second channel 110, thereby ensuring that the ions can be delivered to the human body.

[0141] In some embodiments, the electrode mounting seat 130 is arranged opposite to the second air outlet 140, so that the emitting tip of the emitting electrode 300 is opposite to the second air outlet 140, thereby enabling the ions released by the emitting electrode 300 to flow out opposite to the second air outlet 140.

[0142] In some embodiments, the second air inlet 150 of the second channel 110 is in communication with the second air outlet 140. At this time, the gas flowing in from the second air inlet 150 can flow to the second air outlet 140. In this way, the wind energy loss in the second channel 110 can be reduced, and the long and narrow channel can accelerate the airflow, thereby helping to improve the delivery distance of the ions.

[0143] In some embodiments, the electrode mounting seat 130 includes a mounting body 135 and a mounting cavity 132. The mounting cavity 132 penetrates through the mounting body 135. In some embodiments, the emitting electrode 300 is arranged at the first end opening (such as the front side opening) of the mounting cavity 132. The first end of the emitting electrode 300 is located outside the mounting cavity 132, and the second end of the emitting electrode 300 opposite to the first end is located in the first end opening of the mounting cavity 132.

[0144] For example, the second end of the emitting electrode 300 opposite to the emitting tip is inserted into the mounting cavity 132 through the first end opening of the mounting cavity 132 to be fixed to the electrode mounting seat 130. The emitting tip (i.e., the first end) of the emitting electrode 300 protrudes from the mounting cavity 132 and is arranged opposite to the second air outlet 140. In this way, the emitting tip is in sufficient contact with the air, thereby ensuring that the ions can smoothly diffuse out.

[0145] In some embodiments, referring to FIG. 11, the negative oxygen water ion generating device 50 further includes a high-voltage wire 160. The first end of the high-voltage wire 160 is coupled with the negative high-voltage power supply 600, and the second end of the high-voltage wire 160 is coupled with the emitting electrode 300 to supply power to the emitting electrode 300.

[0146] For example, the first end of the high-voltage wire 160 is coupled with the negative high-voltage power supply 600, and the second end of the high-voltage wire 160 is inserted into the mounting cavity 132 through the second end opening (such as the rear side opening) of the mounting cavity 132 to supply power to the emitting electrode 300.

[0147] In this way, the transmitting electrode 300 and the high-voltage wire 160 are mounted to the electrode mounting seat 130 from different sides, facilitating the mounting of the transmitting electrode 300 and the high-voltage wire 160, thereby improving the assembly efficiency of the transmitting electrode 300 and the high-voltage wire 160.

[0148] In some embodiments, the high-voltage wire 160 extends into the mounting cavity 132 through the second air inlet 150 of the second passage 110. In this way, the rotating part 100 does not need to be provided with a corresponding wire hole for the high-voltage wire 160, facilitating the mounting of the high-voltage wire 160, thereby improving the assembly efficiency of the high-voltage wire 160.

[0149] In some embodiments, referring to FIGS. 10, 11 and 15, the motor mounting seat 130 further comprises a first limiting part 131 (limiting step), which is arranged on the inner wall of the mounting cavity 132.

[0150] In some embodiments, the mounting cavity 132 comprises a first sub-mounting cavity 1321, which is formed between the first limiting part 131 and the first end opening of the mounting cavity 132. The transmitting electrode 300 is arranged in the first sub-mounting cavity 1321.

[0151] In some embodiments, the mounting cavity 132 further comprises a second sub-mounting cavity 1322, which is formed between the first limiting part 131 and the second end opening of the mounting cavity 132. The high-voltage wire 160 is arranged in the second sub-mounting cavity 1322.

[0152] In some embodiments, the motor mounting seat 130 further comprises a communication part 133 (groove), which is arranged on the inner wall of the mounting cavity 132 and penetrates the first sub-mounting cavity 1321 and the second sub-mounting cavity 1322.

[0153] In this way, during assembly, the second end of the transmitting electrode 300 opposite to the transmitting tip abuts against the first limiting part 131 to be fixed in the first sub-mounting cavity 1321. The high-voltage wire 160 is inserted into the second sub-mounting cavity 1322 to be coupled with the transmitting electrode 300.

[0154] It can be understood that when the transmitting electrode 300 is inserted into the mounting cavity 132, when the transmitting electrode 300 abuts against the first limiting part 131, it indicates that the transmitting electrode 300 is inserted in place. The arrangement of the first limiting part 131 can limit the insertion distance of the transmitting electrode 300, ensuring that the depths of the transmitting electrodes 300 of different batches inserted into the mounting cavity 132 are the same.

[0155] In some embodiments, the negative oxygen water ion generating device 50 further comprises an electrically conductive carbon paste 170. A portion of the electrically conductive carbon paste 170 is filled in the second sub-mounting cavity 1322, and another portion of the electrically conductive carbon paste 170 flows into the first sub-mounting cavity 1321 through the communication part 133 to wrap the emitting electrode 300.

[0156] It should be noted that the material of the electrically conductive carbon paste 170 mainly comprises epoxy resin and carbon powder, and the carbon powder has electrical conductivity. The electrically conductive carbon paste 170 can play the roles of electrical conduction and fixation.

[0157] On the one hand, the electrically conductive carbon paste 170 can realize the coupling between the emitting electrode 300 and the high-voltage wire 160. Since the emitting electrode 300 contains water-absorbing factors inside, and after the emitting electrode 300 absorbs water, if the high-voltage wire 160 contacts the emitting electrode 300, under the condition of negative high voltage, the copper wire of the high-voltage wire 160 will lose electrons and thus electrochemical corrosion will occur. Therefore, by realizing the coupling between the emitting electrode 300 and the high-voltage wire 160 through the electrically conductive carbon paste 170, the contact between the emitting electrode 300 and the high-voltage wire 160 can be avoided, so as to avoid the electrochemical corrosion of the copper wire of the high-voltage wire 160.

[0158] On the other hand, the arrangement of the electrically conductive carbon paste 170 can also play the role of fixing the emitting electrode 300. The other portion of the electrically conductive carbon paste 170 flows into the first sub-mounting cavity 1321 through the communication part 133 to wrap the emitting electrode 300. In this way, not only the fixing effect of the emitting electrode 300 is improved, but also the electrical conductivity of the negative oxygen water ion generating device 50 is improved.

[0159] In some embodiments, the installation process of the emitting electrode 300 comprises:

[0160] The second end of the high-voltage wire 160 is exposed to the internal copper wire, for example, the length of the exposed copper wire is 5mm to 8mm.

[0161] It should be noted that if the length of the copper wire is shorter than 5mm, the connection firmness between the copper wire and the electrically conductive carbon paste 170 and the electrical conduction effect between the high-voltage wire 160 and the electrically conductive carbon paste 170 can be reduced. If the length of the copper wire is greater than 8mm, a part of the copper wire can be exposed to the electrically conductive carbon paste 170 or even the mounting cavity 132, thereby causing the risk of electric leakage and reducing the reliability of the negative oxygen water ion generating device 50.

[0162] The exposed end of the copper wire is extended into the second sub-mounting cavity 1322 from the second end of the mounting cavity 132.

[0163] A preset weight of 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, the height of the conductive carbon paste 170 exceeds the first limiting portion 131, and a part of the conductive carbon paste 170 enters the first sub-mounting cavity 1321.

[0164] The emitting electrode 300 is inserted into the first sub-mounting cavity 1321 through the first end opening of the mounting cavity 132 until the emitting electrode 300 abuts against the first limiting portion 131. In the process of insertion, the conductive carbon paste 170 is extruded by the emitting electrode 300, so that the conductive carbon paste 170 wraps the end of the emitting electrode 300 opposite to the emitting tip.

[0165] After the emitting electrode 300 is mounted into the first sub-mounting cavity 1321, the conductive carbon paste 170 is allowed to solidify for a preset time period, for example, 24 hours. At this time, the emitting electrode 300 can be tightly mounted in the mounting cavity 132.

[0166] In some embodiments, the working principle of the negative oxygen water ion generating device 50 includes that the negative high-voltage power supply 600 transmits high voltage to the conductive carbon paste 170 through the high-voltage wire 160, and then transmits the high voltage to the carbon fiber electrode of the emitting electrode 300 through the conductive carbon paste 170. The carbon fiber electrode contains a large number of water absorption factors inside, which can absorb water from the air. The carbon fiber electrode includes an infinite number of carbon fibers arranged in a preset order, and each carbon fiber end corresponds to an emitting tip. Therefore, the electrode end corresponds to a large number of emitting tips designed. The emitting tips ionize the water in the electrode and the oxygen in the air to generate nanometer water ions rich in hydroxyl radicals and high-concentration negative oxygen ions, which are discharged into the air from the second air outlet 140. Thus, the indoor space 2 is purified of pollutants such as microorganisms, particulate matter, volatile organic compounds (VOC), and the like. In this process, the oxygen generator 5 is turned on to increase the oxygen content of the indoor air.

[0167] In some embodiments, referring to FIGS. 11 and 16, the electrode mounting seat 130 further includes an air guide portion 134 (air guide surface), which is arranged on the outer wall of the end of the mounting seat body 135 facing the second air inlet 150 to play a role of air guide, thereby reducing the air flow resistance and noise at the second air inlet 150.

[0168] In some embodiments, referring to FIGS. 10 to 12, the negative oxygen water ion generating device 50 further includes a mounting portion 200, and the rotating portion 100 is mounted to the indoor unit 1 through the mounting portion 200.

[0169] It can be understood that the mounting portion 200, as a mounting carrier of the rotating portion 100, can realize the rotating connection with the rotating portion 100.

[0170] For example, referring to FIG. 7 and FIG. 17, the mounting portion 200 includes a mounting portion body 230 and at least one first fitting portion 212. The mounting portion body 230 includes a mounting space 240 configured to mount the rotating portion 100. The first fitting portion 212 is disposed on a side wall of the mounting portion body 230 that forms the mounting space 240.

[0171] For example, the at least one first fitting portion 212 includes two first fitting portions 212. The two first fitting portions 212 are respectively disposed on the inner walls of two side walls of the mounting portion body 230 that are opposite to each other.

[0172] The rotating portion 100 includes a rotating portion body 111 and at least one second fitting portion 190. The at least one second fitting portion 190 is disposed on an outer wall of the rotating portion body 111.

[0173] For example, the at least one second fitting portion 190 includes two second fitting portions 190. The two second fitting portions 190 are disposed on two sides of the outer wall of the rotating portion body 111 that are opposite to each other. The first fitting portion 212 cooperates with the corresponding second fitting portion 190 to rotatably hold the rotating portion 100 in the mounting space 240.

[0174] In some embodiments, the rotating portion 100 has a spherical shape, the two first fitting portions 212 are oppositely arranged, and the first fitting portion 212 has a concave shape that is adapted to the spherical shape of the rotating portion 100. The rotating portion 100 is disposed between the two first fitting portions 212. In this way, the mounting portion 200 can hold the rotating portion 100 and ensure rotation of the rotating portion 100.

[0175] In some embodiments, the mounting portion 200 includes two first sub-mounting portions 210 (first mounting arms) that are oppositely spaced apart, the mounting space 240 is formed between the two first sub-mounting portions 210, and the first fitting portion 212 is disposed on a side wall of the mounting space 240 toward any one of the two first sub-mounting portions 210. That is, the two first sub-mounting portions 210 are respectively provided with the first fitting portion 212 on the side opposite to each other. In this way, the mounting portion 200 holds the rotating portion 100 from opposite sides of the rotating portion 100, which can improve the reliability of the holding structure.

[0176] In some embodiments, the mounting portion 200 further includes two extension portions 211. The two extension portions 211 are respectively disposed on one end of the two first sub-mounting portions 210 close to the rotating portion 100 and extend downward. The two first fitting portions 212 are respectively disposed on the side opposite to each other of the two extension portions 211.

[0177] It should be noted that the extension part 211 has a preset volume and surface area to provide sufficient forming space for the first fitting part 212, thereby increasing the area of the first fitting part 212. In this way, it is helpful to improve the clamping reliability of the rotating part 100.

[0178] In some embodiments, the mounting part 200 further comprises a second sub-mounting part 220 (second mounting arm) connected between the two first sub-mounting parts 210. For example, the second sub-mounting part 220 is connected to the end of the two first sub-mounting parts 210 away from the rotating part 100, preventing interference with the mounting and rotation of the rotating part 100.

[0179] In some embodiments, referring to FIGS. 7 and 8, the negative oxygen water ion generating device 50 further comprises a driving part 700 configured to drive the rotating part 100 to rotate in a three-dimensional space to adjust the delivery direction of the ions.

[0180] The driving part 700 is configured to drive the rotating part 100 to rotate in at least one of the first plane or the second plane to adjust the delivery direction of the ions.

[0181] For example, in some embodiments, the driving part 700 is configured to drive the rotating part 100 to rotate in the first plane extending horizontally to adjust the delivery direction of the ions in the first plane.

[0182] In some embodiments, the driving part 700 is configured to drive the rotating part 100 to rotate in the second plane extending vertically to adjust the delivery direction of the ions in the second plane.

[0183] In some embodiments, the driving part 700 is configured to drive the rotating part 100 to rotate in the first plane and the second plane simultaneously, and the first plane extends in a transverse direction and the second plane extends in a vertical direction, to adjust the delivery direction of the ions in a three-dimensional space.

[0184] In some embodiments, referring to FIGS. 7, 8, and 10, the driving part 700 comprises 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 the first plane extending in a transverse direction.

[0185] In some embodiments, the first sub-driving part 710 is a horizontal stepping motor, and a power output shaft of the horizontal stepping motor is connected to the rotating part 100.

[0186] In some embodiments, the first sub-driving part 710 is arranged on the top of the rotating part 100. The power output shaft of the first sub-driving part 710 is opposite to the spherical center of the rotating part 100.

[0187] In some embodiments, referring to FIG. 19, the first sub-driving part 710 comprises a first sub-driving part body 715 and a power output shaft 716, which is arranged at one end (e.g. the bottom end) of the first sub-driving part body 715 close to the rotating part 100.

[0188] In some embodiments, the first sub-driving part 710 further comprises a clamping part 711 (rectangular body). For example, the clamping part 711 is arranged at one end (e.g. the bottom end) of the power output shaft 716 close to the rotating part 100.

[0189] In some embodiments, the first sub-driving part 710 further comprises a first hole 712 (first pin hole), which is arranged through the clamping part 711.

[0190] Referring to FIG. 18, the rotating part 100 further comprises a first mounting member 180. The first mounting member 180 is arranged at one end (e.g. the top end) of the rotating part body 111 opposite to the first sub-driving part 710. The first mounting member 180 cooperates with the clamping part 711 to achieve the fixed connection between the rotating part 100 and the first sub-driving part 710.

[0191] In some embodiments, the first mounting member 180 comprises a first mounting member body 183 and a second limiting part 181 (mounting hole). For example, the second limiting part 181 is a rectangular mounting hole. The second limiting part 181 is arranged in the first mounting member body 183. The shape of the second limiting part 181 is adapted to the clamping part 711 to be clamped with the clamping part 711.

[0192] In some embodiments, the clamping part 711 is processed into a rectangular body. It can be understood that arranging the clamping part 711 as a rectangular body is conducive to increasing the stability of the clamping between the clamping part 711 and the second limiting part 181.

[0193] In some embodiments, the first mounting member 180 further comprises a second hole 182 (second pin hole), which is arranged on the side wall of the first mounting member body 183 and is arranged opposite to the first hole 712.

[0194] For example, after the clamping part 711 is inserted into the second limiting part 181, a pin can be inserted through the first hole 712 and the second hole 182 to fix the clamping part 711 in the second limiting part 181, so as to achieve the fixed installation of the first sub-driving part 710 and the rotating part 100.

[0195] It can be understood that, referring to FIGS. 12 and 19, the power output shaft 716 of the first sub-driving part 710 rotates to drive the rotating part 100 to rotate in the horizontal plane.

[0196] In some embodiments, the driving part 700 further comprises a second sub-driving part 720 configured to drive the rotating part 100 to rotate in a second plane extending along the vertical direction. The second sub-driving part 720 is fixedly arranged on the mounting part 200. For example, the second sub-driving part 720 is fixedly arranged on the second sub-mounting part 220.

[0197] In some embodiments, the driving part 700 further comprises a transmission linkage assembly 730 arranged between the power output shaft of the second sub-driving part 720 and the first sub-driving part 710.

[0198] For example, the second sub-driving part 720 is a vertical stepping motor, and the power output shaft of the vertical stepping motor is connected with the transmission linkage assembly 730.

[0199] In some embodiments, the transmission linkage assembly 730 comprises a first linkage 731 and a second linkage 732, and the first linkage 731 is rotationally connected with the second linkage 732. One end of the first linkage 731 is rotationally connected with the first sub-driving part 710. One end of the second linkage 732 is fixedly connected with the power output shaft of the second sub-driving part 720.

[0200] Referring to FIG. 13, the second sub-driving part 720 rotates and drives the first sub-driving part 710 to move through the transmission action of the first linkage 731 and the second linkage 732. The first sub-driving part 710 further transmits the force to the rotating part 100, so as to realize the rotation of the rotating part 100 in the vertical plane. FIGS. 14A-14D show the rotating postures of the rotating part 100 at different angle positions.

[0201] In some embodiments, referring to FIGS. 8, 19 and 20, the first sub-driving part 710 further comprises a second mounting member 713 (second mounting seat) arranged on the side of the first sub-driving part body 715 close to the second sub-driving part 720.

[0202] In some embodiments, the second mounting member 713 comprises a second mounting member body 717 and a mounting shaft 714 arranged on the side of the second mounting member body 717 close to the second sub-driving part 720, and one end of the first linkage 731 is rotationally connected with the mounting shaft 714.

[0203] In some embodiments, the driving part 700 is located above the rotating part 100. In this way, it is convenient to access the first channel 400, the high-voltage wire 160 and the like into the rotating part 100 from the lower side of the second sub-mounting part 220.

[0204] In some embodiments of the present disclosure, the air conditioner 1000 controls the rotation of the rotating part 100 in the horizontal direction through the first sub-driving part 710, and controls the rotation of the rotating part 100 in the vertical direction through the second sub-driving part 720. The rotating part 100 can rotate in both the horizontal direction and the vertical direction at the same time, and the rotations in the two directions do not affect each other. In this way, it is helpful to improve the adjustment efficiency of the rotation angle of the rotating part 100.

[0205] In some embodiments, referring to FIGS. 2B and 2C, the negative oxygen water ion generating device 50 includes a control assembly 800. The control assembly 800 can be independently arranged and coupled to the controller 8 through a line, or can be integrated into the controller 8. The control assembly 800 includes a main control board, a micro controller unit (MCU), a first sub-control assembly 801, and a second sub-control assembly 802. The first sub-control assembly 801 is configured to control the rotation of the first sub-driving part 710, and the second sub-control assembly 802 is configured to control the rotation of the second sub-driving part 720. The control assembly 800 controls the rotation direction and angle of the rotating part 100 by controlling the rotation angles of the first sub-driving part 710 and the second sub-driving part 720.

[0206] For example, the control process of the control assembly 800 on the rotation direction and angle of the rotating part 100 includes:

[0207] The air conditioner 1000 is turned on.

[0208] The main control board determines whether the current positions of the first sub-driving part 710 and the second sub-driving part 720 are the initial state. If yes, the next step is entered. If not, the MCU will send a signal to the first sub-control assembly 801 and the second sub-control assembly 802 to adjust the first sub-driving part 710 and the second sub-driving part 720 to the initial state.

[0209] It should be noted that the initial state is, for example, the position of the second air outlet 140 of the rotating part 100 in FIG. 7 facing the front. That is, the second air outlet 140 is located at the middle position of the horizontal plane in FIG. 12, and at the middle position of the vertical plane in FIG. 13.

[0210] The main control board obtains the target position information of the ions to be delivered.

[0211] It should be noted that the target position information can be obtained by the control assembly 800 through the second sensor 4, or can be input by the user through the remote controller or the mobile terminal (which has established a connection with the air conditioner 1000). The target position information can be the position coordinates of the person in the indoor space 2, or the position information to which the rotating part 100 needs to rotate.

[0212] The main control board converts the target position information into a target position signal and transmits the target position signal to the MCU. The MCU converts the target position signal into a rotation signal of the first sub-driving part 710 and a rotation signal of the second sub-driving part 720, and transmits the rotation signal of the first sub-driving part 710 to the first sub-control assembly 801 and transmits the rotation signal of the second sub-driving part 720 to the second sub-control assembly 802, so that the first sub-control assembly 801 and the second sub-control assembly 802 control the corresponding motors to rotate by corresponding angles, respectively.

[0213] In this way, the first sub-driving part 710 drives the rotation part 100 to rotate in the horizontal direction, and the second sub-driving part 720 drives the rotation part 100 to rotate in the vertical direction, until the second air outlet 140 rotates to the target position, so that the ions can be transported to the target position.

[0214] It should be noted that the rotation angles of the first sub-driving part 710 and the second sub-driving part 720 corresponding to the target position information can be calculated by a logical algorithm.

[0215] For example, if the target position coordinates are the position coordinates of a person in the indoor space 2, the position to which the rotation part 100 needs to rotate is determined according to the position coordinates of the person in the indoor space 2, and the rotation angles of the first sub-driving part 710 and the second sub-driving part 720 are determined according to the position to which the rotation part 100 needs to rotate.

[0216] The air conditioner 1000 in some embodiments of the present disclosure acquires target position information, converts the target position information into rotation angle signals of the first sub-driving part 710 and the second sub-driving part 720 by combining a logical algorithm, and controls the first sub-driving part 710 and the second sub-driving part 720 to rotate according to the rotation signals, so as to drive the rotation part 100 to rotate to the target position. In this way, the control of the rotation part 100 is facilitated.

[0217] It can be understood that, in some embodiments of the present disclosure, the first sub-driving part 710 is a horizontal stepping motor, and the second sub-driving part 720 is a vertical stepping motor. Therefore, the reachable positions of the rotation part 100 are limited, and the reachable positions of the rotation part 100 are related to the number of steps of the horizontal stepping motor and the vertical stepping motor. After determining the position to which the rotation part 100 needs to rotate, the nearest reachable position to the position to which the rotation part 100 needs to rotate can be determined first, and then the rotation angles of the first sub-driving part 710 and the second sub-driving part 720 are determined according to the reachable position. In this way, the ions can be transported to the nearest position to the target position.

[0218] In some embodiments, in order to reduce the error between the final rotation position of the rotation part 100 and the target position, and to improve the accuracy of the final rotation position of the rotation part 100, the number of steps of the horizontal stepper motor and the vertical stepper motor in the preset rotation angle range of the first sub-driving part 710 and the second sub-driving part 720 can be increased. In this way, the number of reachable position points of the horizontal stepper motor and the vertical stepper motor is increased, and the resolution of the position points divided by the indoor space 2 in the preset rotation angle range of the rotation part 100 is improved.

[0219] For example, in the case of the maximum rotatable angle a° of the rotation part 100 in the horizontal plane (see FIG. 12), the preset rotation angle of the corresponding first sub-driving part 710 is c°.

[0220] In the case of the maximum rotatable angle b° of the rotation part 100 in the vertical plane (see FIG. 13), the preset rotation angle of the corresponding second sub-driving part 720 is d°.

[0221] Suppose the number of steps of the horizontal stepper motor and the vertical stepper motor in the preset rotation angle range is 7 steps, then a total of 49 reachable position points can be arranged in the indoor space 2. If the number of steps of the horizontal stepper motor and the vertical stepper motor in the preset angle range is increased to 10 steps, then a total of 100 reachable position points can be arranged in the indoor space 2, and the accuracy of the rotation position of the rotation part 100 is improved.

[0222] In some embodiments, the air supply pipeline part of the second channel 110 that communicates with the rotation part 100 is a flexible pipeline to adapt to the rotation of the rotation part 100.

[0223] In some embodiments, the negative oxygen water ion generating device 50 includes one of a directional delivery mode or a sweeping mode.

[0224] In the directional delivery mode, the rotation part 100 is kept at a set angle and position to deliver ions in a directional manner. In the directional delivery mode, the driving part 700 drives the rotation part 100 to rotate by a corresponding angle according to the target position information, so that the second air outlet 140 can be directed towards the target position, thereby delivering ion wind 3 to the target position.

[0225] In the sweeping mode, the rotation part 100 reciprocally rotates in a set plane to deliver ions in a sweeping manner in the set plane. The set plane includes at least one of the first plane or the second plane.

[0226] In some embodiments, the sweeping mode includes at least one of a horizontal sweeping mode, a vertical sweeping mode, or a three-dimensional (3D) sweeping mode.

[0227] In the horizontal blowing mode, the rotating part 100 reciprocates in a first plane extending in the lateral direction to deliver ions in the form of blowing in the first plane. Referring to FIG. 12, the first sub-driving part 710 drives the rotating part 100 to reciprocate in the first plane, realizing blowing of the ion wind 3 in the horizontal direction.

[0228] In the vertical blowing mode, the rotating part 100 reciprocates in a second plane extending in the vertical direction to deliver ions in the form of blowing in the second plane. Referring to FIG. 13, the second sub-driving part 720 drives the rotating part 100 to reciprocate in the second plane, realizing blowing of the ion wind 3 in the vertical direction.

[0229] In the 3D blowing mode, the rotating part 100 reciprocates in the first plane and the second plane to deliver ions to different directions in the three-dimensional space. The first sub-driving part 710 and the second sub-driving part 720 work to drive the rotating part 100 to reciprocate in the first plane and the second plane at the same time, realizing delivery of the ion wind 3 to different directions in the indoor space 2.

[0230] In some embodiments, the controller 8 is further configured to:

[0231] In the case that the indoor unit 1 is started 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 acquired. The size information of the indoor space 2 includes the size of the indoor space 2, the size of the door and window, and the position information of the door and window.

[0232] According to the acquired size information of the indoor space 2 where the indoor unit 1 is located and the installation position information of the indoor unit 1, the indoor space 2 is three-dimensionally coordinate-dotted to form a three-dimensional space matrix.

[0233] The first rotation angle A of the first sub-driving part and the second rotation angle B of the second sub-driving part corresponding to the three-dimensional coordinate point in the three-dimensional space matrix are determined, and the mapping relationship between the three-dimensional coordinate point and the first rotation angle A and the second rotation angle B is stored.

[0234] The second sensor 4 is turned on to acquire the position of the personnel in the indoor space 2 and the target three-dimensional coordinate value where the personnel is located in the indoor space 2.

[0235] According to the acquired target three-dimensional coordinate value and the stored mapping relationship between the three-dimensional coordinate point and the first rotation angle A and the second rotation angle B, the target first rotation angle and the target second rotation angle are determined, and the first sub-driving part 710 and the second sub-driving part 720 are controlled to operate according to the target first rotation angle and the target second rotation angle, so as to deliver the ion wind 3 to the target position (i.e. the target three-dimensional coordinate value where the indoor personnel is located).

[0236] Referring to FIG. 1C, when the indoor unit 1 is first powered on, the controller 8 acquires the size information of the indoor space 2 in which the indoor unit 1 is located and the installation position information of the indoor unit 1, and saves the information. The controller 8 performs three-dimensional space coordinate decomposition at a predetermined interval (for example, 0.3-1 m) to form a three-dimensional space matrix matching the indoor space 2. The three-dimensional space matrix includes at least one three-dimensional coordinate point.

[0237] The controller 8 determines the rotation range of the rotating part 100 according to the three-dimensional space matrix.

[0238] For example, the controller 8 converts any one of the at least one three-dimensional coordinate point 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 the any one of the at least one three-dimensional coordinate point and the first rotation angle A and the second rotation angle B, so as to realize ion delivery in different directions in the indoor space 2.

[0239] In this way, the rotation angles of the first sub-driving part 710 and the second sub-driving part 720 corresponding to each coordinate position in the indoor space 2 are calculated and saved in advance, which 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 use, and improves the stability of the air conditioner 1000.

[0240] In some embodiments, if the target three-dimensional coordinate value of the person exceeds the maximum turning limit of the rotating part 100, the turning angle at this time is the maximum turning angle and is saved, so that the ion wind 3 can blow to the target area as much as possible.

[0241] In some embodiments, the controller 8 is further configured to:

[0242] The indoor personnel position is acquired by the second sensor 4, and the target three-dimensional coordinate value of the person is determined according to the indoor personnel position.

[0243] According to the mapping relationship between the stored three-dimensional coordinate point and the first rotation angle A and the second rotation angle B, the target first rotation angle and the target second rotation angle corresponding to the target three-dimensional coordinate value are determined.

[0244] According to the determined target first rotation angle and target second rotation angle, the first sub-driving part 710 and the second sub-driving part 720 are controlled to operate to drive the rotating part 100 to operate to the target position, so that the negative oxygen water ion generating device 50 delivers ions to the position where the person is located, thereby improving the efficiency of delivering negative oxygen ions to the target position.

[0245] In some embodiments, the second sensor 4 is further configured to detect the number of people in the indoor space. The controller 8 is further configured to:

[0246] The number of people in the indoor space 2 and the target three-dimensional coordinate value of the location of the people are determined by the second sensor 4, and the rotation angle of the rotating part 100 is adjusted according to the movement of the location of the people, so that the negative oxygen ions can be delivered to the surrounding of the human body.

[0247] In some embodiments, the controller 8 is further configured to:

[0248] The number of people N in the indoor space 2 is detected by the second sensor 4.

[0249] If it is determined that the number of people N is greater than 1, the location coordinate M of any one of the N people in the indoor space 2 is detected by the second sensor 4, and the distance D1, D2, D3, … DN of the any one person from the first air outlet 11 is calculated.

[0250] The location coordinates of the people are arranged in order from near to far according to the distance, and then the first sub-driving part 710 and the second sub-driving part 720 are controlled to rotate, so that the ion wind 3 is blown from the location coordinate of the closest person to the location coordinate of the farthest person.

[0251] During the blowing process, if it is determined that D>Dt, the second fan 500 is turned on, and after one blowing cycle ends, the second fan 500 is turned off.

[0252] If it is determined that the number of people N is equal to 1, the location coordinate of the person in the indoor space 2 is detected by the second sensor 4. The rotation angle of the first sub-driving part 710 and the second sub-driving part 720 is determined according to the location coordinate of the person, so that the ion wind 3 is blown to the surrounding of the human body. The distance D of the person from the first air outlet 11 is calculated according to the location coordinate of the person.

[0253] During the blowing process, if it is determined that D>Dt, the second fan 500 is turned on to increase the delivery distance of the ion wind 3. After a preset time interval T2, the location coordinate of the person in the indoor space 2 is detected again by the second sensor 4. If it is determined that D≤Dt, the second fan 500 is turned off, and after a preset time interval T2, the location coordinate of the person in the indoor space 2 is detected again by the second sensor 4.

[0254] For example, after the negative oxygen water ion generating device 50 is turned on, the second sensor 4 first determines the number of people N in the current indoor space 2.

[0255] If N = 1, the second sensor 4 detects the position of the person in the indoor space 2, i.e. determines the three-dimensional coordinate value of the person (for example, the three-dimensional coordinate value of the head of the person). The controller 8 determines the rotation angle of the rotating part 100 in the horizontal and vertical directions according to the three-dimensional coordinate value and the mapping relationship, so that the ion wind 3 blows around the human body.

[0256] In addition, the controller 8 also determines the distance D of the person from the first air outlet 11 according to the position coordinate of the person detected by the second sensor 4.

[0257] If it is determined that D ≥ the first preset distance Dt, it indicates that the person is far away from the first air outlet 11 at this time, and the power provided by the first fan 30 cannot meet the demand of long-distance transportation of negative oxygen ions. At this time, the controller 8 controls to open the second fan 500, so as to provide power for the gas flow of the second channel 110 of the negative oxygen ion generating device 50, improve the blowing speed of the ion wind 3, and then the negative oxygen ions can be blown to a farther target position.

[0258] If it is determined that D < the first preset distance Dt, it indicates that the person is close to the first air outlet 11 at this time, and the power provided by the first fan 30 can meet the demand of ion transportation distance. Therefore, the second fan 500 is closed at this time.

[0259] After the interval preset time T2, the second sensor 4 detects the position coordinate of the person in the indoor space 2 again, and adjusts the transportation angle of the ion wind 3 and the opening and closing of the second fan 500 according to the updated position.

[0260] If it is determined that N > 1, the controller 8 detects the number N of persons in the indoor space 2 and the position coordinate M of any one of the N persons through the second sensor 4, and calculates the distance D1, D2, D3, … DN of the any one person from the first air outlet 11.

[0261] The controller 8 arranges the position coordinates of the N persons according to the order from near to far, and then controls the rotation angle of the rotating part 100 in the horizontal and vertical directions, controls the ion wind 3 to start blowing from the position closest to the person to the position farthest from the person, and completes a blowing cycle. The blowing time of the position where the any one person is located is T3.

[0262] During the blowing process, the controller 8 determines the distance D of the person from the first air outlet 11, and when D ≥ the first preset distance Dt, the second fan 500 is turned on, and after one cycle, the second fan 500 is turned off.

[0263] After the first round of purging, the controller 8 controls the second sensor 4 to immediately reconfirm the personnel position coordinates in the indoor space 2, and re-ranks the distance of any one person from the first air outlet 11: D1, D2, D3, …, DN.

[0264] According to the latest ranking order, the controller 8 controls the negative oxygen water ion generating device 50 to perform purging again, and timely starts the second fan 500.

[0265] It should be noted that, due to the dust reduction effect of the negative ion equipment, part of the settled dust may adhere to the wall during use of the negative ion equipment, which may cause the wall around the negative ion equipment to become black, thereby causing the “black wall phenomenon”. It can be understood that the higher the concentration of negative ions generated by the negative ion equipment, the stronger the purification ability, and the more obvious the “black wall phenomenon”.

[0266] It can be understood that the negative oxygen water ion generating device 50 releases negative oxygen ions and nanometer water ions into the air. At a position close to the emission tip of the emission electrode 300, the concentration of negative oxygen ions is high, and part of the negative oxygen ions are easily attached to the surface of the wall or the shell around the emission electrode 300, thereby causing part of the dust in the air to be attached to the wall or the shell, and causing the “black wall phenomenon”. In addition, some particulate matters combine with negative oxygen ions to become negatively charged, and the negatively charged particulate matters move to grounded objects under the action of electric field force, and finally deposit on the surface of the grounded objects. With the continuous deposition of particulate matters, the “black wall phenomenon” will occur around the emission electrode 300.

[0267] In some embodiments, referring to FIG. 2A, the shell 10 of the air conditioner 1000 includes a shell body 101. The shell 10 further includes a front side plate 102, which is arranged at a side (i.e., a front side) of the shell body 101 close to a user. The first air outlet 11 is arranged on the front side plate 102.

[0268] In some embodiments, the shell 10 further includes a panel 40, which is arranged at a side of the front side plate 102. The negative oxygen water ion generating device 50 is arranged on the panel 40. For example, the panel 40 is a plastic piece.

[0269] In some embodiments, referring to FIG. 22, the panel 40 includes a panel body 43. The panel 40 further includes an opening 41 arranged 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 communicated with the second air outlet 140 of the rotating part 100, and the emission electrode 300 extends out through the second air outlet 140 and the opening 41, so that the ions released by the emission electrode 300 flow into the indoor space 2 without obstruction, facilitating the escape and diffusion of the ions.

[0270] It should be noted that the panel 40 and the front side plate 102 can be a split structure, so as to facilitate the assembly of the panel 40 and the negative oxygen ion generating device 50.

[0271] The panel 40 and the front side plate 102 can also be an integral structure, which is beneficial to simplify the installation steps and improve the installation efficiency.

[0272] In some embodiments, the panel 40 further comprises a clearance portion 44 (such as a tapered surface), which is arranged at the circumferential edge of the panel body 43 close to the opening 41.

[0273] In some embodiments, the clearance portion 44 extends in the direction of the shell body 101 (i.e. from front to back), so as to avoid the end of the negative oxygen ion generating device 50 extending out of the panel body 43, thereby protecting the negative oxygen ion generating device 50.

[0274] In some embodiments, the inner diameter of the clearance portion 44 decreases in the direction of the shell body 101. In this way, the clearance portion 44 can provide a rotating space for the rotating portion 100, avoid blocking the diffusion of ions, and facilitate the escape and diffusion of ions.

[0275] It should be noted that although the panel 40 is not directly grounded, in the case that the air humidity is large or the air conditioner 1000 is in a cooling mode, resulting in condensation on the surface of the panel 40, since the panel 40 is in close contact with the air conditioner grounding sheet metal, the panel 40 is equivalent to a weak ground. Therefore, after a long time of use, the panel 40 will also appear a "black wall phenomenon", causing the panel 40 to be dirty.

[0276] In some embodiments of the present disclosure, the panel 40 contains 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 ion generating device 50 are repelled by the panel 40 and far away from the panel 40, thereby inhibiting the negative ions from adhering to the panel 40 and avoiding the "black wall phenomenon" caused by the positive particles in the air being adsorbed to the panel 40. On the other hand, the particles in the air that are combined with the negative oxygen ions and are negatively charged are repelled by the panel 40 and far away from the panel 40, thereby avoiding the deposition of the negatively charged particles on the panel 40 and avoiding the "black wall phenomenon" of the panel 40.

[0277] It should be noted that the panel 40 is a plastic part, and metal conductive particles are added to the plastic particles for injection molding of the panel 40, which increases the conductivity of the panel 40 without affecting the color of the panel 40.

[0278] In some embodiments, the negative high voltage power supply 600 provides a negative high voltage to the panel 40, so that a large amount of negative charges are distributed on the panel 40. When the negatively charged particles in the air approach the panel 40, the negatively charged particles are repelled by the panel 40, so that the negatively charged particles are far away from the panel 40, and thus the negatively charged particles are deposited on the panel 40.

[0279] Referring to 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 the negative ion generating device (e.g., the 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.

[0280] For example, the first negative high voltage power supply line 610 provides a negative high voltage ranging from -3000V to -6000V. The second negative high voltage power supply line 620 provides a negative high voltage ranging from -500V to -2000V.

[0281] It should be noted that if the negative high voltage of the first negative high voltage power supply line 610 is lower than -3000V, the electrolysis capability of the negative oxygen water ion generating device 50 can be reduced, resulting in a decrease in the concentration of negative oxygen ions generated by the negative oxygen water ion generating device 50, and thus a decrease in the purification capability of the negative oxygen water ion generating device 50. If the negative high voltage of the first negative high voltage power supply line 610 is higher than -6000V, the electric field intensity of the negative oxygen water ion generating device 50 can be increased, resulting in an increase in the electric shock feeling when a user touches the negative oxygen water ion generating device 50.

[0282] Similarly, if the negative high voltage of the second negative high voltage power supply line 620 is lower than -500V, the negative oxygen ions generated by the negative oxygen water ion generating device 50 and the negatively charged particles in the air can not be far away from the panel 40, and thus the effect of avoiding the occurrence of the "black wall phenomenon" can not be achieved. If the negative high voltage of the second negative high voltage power supply line 610 is higher than -2000V, the electric field intensity of the panel 40 can be increased, resulting in an increase in the electric shock feeling when a user touches the panel 40.

[0283] In some embodiments, a protection resistor is arranged at the high voltage output end of the negative high voltage power supply 600. In this way, since the designed power of the negative oxygen water ion generating device 50 is small, for example, 1W, when a person accidentally touches the emitting electrode 300 or the panel 40, the current flowing through the human body is microamperes, which does not cause adverse effects on the human body.

[0284] In some embodiments, the panel 40 further includes a terminal post 42 arranged at the side of the panel body 43 close to the shell body 101. The second negative high voltage power supply line 620 is connected to the terminal post 42 to supply negative electricity to the panel 40.

[0285] In some embodiments, referring to FIG. 2A and FIG. 2B, the indoor unit 1 further comprises a third sensor 4 (a distance sensor) 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 second preset distance, the negative high-voltage power supply 600 stops power supply.

[0286] It should be noted that the negative oxygen water ion generating device 50 and the panel 40 are electrified, and the electric quantity of the negative oxygen water ion generating device 50 and the panel 40 will not cause harm to the human body, but when the person touches the negative oxygen water ion generating device 50 and the panel 40, there will still be a slight instantaneous electric shock feeling.

[0287] In some embodiments, in order to avoid the negative oxygen water ion generating device 50 and the panel 40 causing the human body to feel an electric shock and causing the human body to be uncomfortable, the air conditioner 1000 further comprises a “debug mode”. After the installation of the air conditioner 1000 is completed, the debug personnel also needs to detect the static electricity generated by the negative oxygen water ion generating device 50 and the panel 40 in the electrified state.

[0288] The controller 8 is further configured to:

[0289] If the debug instruction is received, the password input interface is displayed on the control panel 9 or the mobile terminal.

[0290] If it is determined that the password input by the debug personnel is correct, the debug mode is entered. In the debug mode, the debug personnel can check the running state of the air conditioner 1000 in different running modes. For example, the debug personnel can check the running state of the air conditioner 1000 in the cooling mode, the heating mode or the purification mode.

[0291] In the debug mode, if it is determined that the debug personnel controls the air conditioner 1000 to start the “health care mode”, the negative oxygen water ion generating device 50 and the panel 40 are powered on, so as to facilitate the debug personnel to detect the static electricity of the negative oxygen water ion generating device 50 and the panel 40.

[0292] If the debug end instruction is received, the debug mode is closed.

[0293] For example, the air conditioner 1000 further comprises a debug button, and the debug button is arranged on the shell 10. For example, the debug button is arranged on the panel 40. It can be understood that after the debug button is started, the air conditioner 1000 starts the “debug mode”. In the “debug mode”, after the debug personnel selects to start the purification function, the air conditioner 1000 powers on the negative oxygen water ion generating device 50 and the panel 40, so as to facilitate the debug personnel to check the running state of the air conditioner 1000.

[0294] In some embodiments, in order to avoid the negative oxygen water ion generating device 50 and the panel 40 causing the human body to feel an electric shock, the controller 8 is further configured to:

[0295] In the case of turning off the debugging mode, if it is determined that the user turns on the "health and wellness mode", the third sensor 7 is turned on to obtain the distance between the user and the panel 40, and the negative oxygen water ion generating device 50 is powered.

[0296] If it is determined that the distance between the user and the panel 40 is less than the second preset distance (for example, 1 m), the negative oxygen water ion generating device 50 is powered off to avoid accidental contact by the person.

[0297] If it is determined that the distance between the user and the panel 40 is greater than or equal to the second preset distance, the power supply to the negative oxygen water ion generating device 50 is restored, and the negative oxygen water ion generating device 50 resumes operation.

[0298] It can be understood that, after debugging is completed, the indoor unit 1 detects the distance between the person and the panel 40 through the second sensor 7 in subsequent use. If it is determined that the distance between the person and the panel 40 is less than the second preset distance (for example, 1 m), the negative high-voltage power supply 600 stops power supply, that is, the negative oxygen water ion generating device 50 and the panel 40 are powered off, thereby avoiding the discomfort caused by the electric shock feeling when the user touches the emitting electrode 300 or the panel 40.

[0299] If it is determined that the distance between the person and the panel 40 is greater than or equal to the second preset distance, the negative high-voltage power supply 600 again supplies power to the negative oxygen water ion generating device 50 and the panel 40.
