Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more particularly to an indoor air conditioner unit. Background Technology

[0002] Negative oxygen ions can release nano-water ions and negative oxygen ions into the air. The main component of nano-water ions is hydroxyl radicals, which have bactericidal properties. Negative oxygen ions not only purify particulate matter but also promote blood circulation and inhibit disease development.

[0003] Currently, negative ion generators are fixed in place and the direction of ion transmission cannot be adjusted. After generation, ions are blown away by the wind. On the one hand, the wind and electric fields are in opposite directions, which can cause the ions to migrate over short distances. On the other hand, negative ions have a short lifespan; if they are not delivered to the area around people in time, they will gradually disappear. A large number of ions are transported to ineffective areas, resulting in a waste of negative ion energy and reducing the air purification and health benefits.

[0004] Furthermore, to improve people's comfort when exposed to drafts, air conditioners are often set to a "wind avoids people" mode. However, the movement of negative air ions is easily affected by the air conditioning airflow. If the air conditioner is operating in "wind avoids people" mode, it becomes even more difficult for negative air ions to reach the area around the human body, thus failing to provide the benefits of healthy breathing. This creates a conflict between comfort and health, making it difficult to reconcile the two.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

A negative oxygen water ion generator is disposed on the housing and configured to ionize the air to release oxygen ions and nano-water ions into the indoor space. The negative oxygen water ion generator includes an emitting electrode and a rotating part. The emitting electrode is configured to ionize the air to release oxygen ions and nano-water ions into the indoor space. The rotating part is configured to drive the emitting electrode to rotate to adjust the ion delivery direction. The rotating part includes a second air duct, the emitting electrode is disposed in the second air duct, and a second air outlet communicating with the second air duct is disposed on the rotating part, the second air outlet being disposed beside the first air outlet.

[0008] On the other hand, an air conditioner indoor unit is provided, including a housing, a first air inlet and a first air outlet, the first air outlet being configured to blow out air conditioning air, an indoor heat exchanger being provided inside the housing and configured to exchange heat with the flowing air, the indoor unit also including a negative oxygen water ion generator, the negative oxygen water ion generator being disposed on the housing and located next to the first air outlet, the air outlet direction of the air conditioning air and the air outlet direction of the ionized air blown out by the negative oxygen water ion generator being independently adjustable, the negative oxygen water ion generator being configured with an independent air duct to provide it with air for ionization.

[0024] In related technologies, negative ion generators use air ionization to produce negative ions. However, since air contains only 21% oxygen, only about 1 / 5 of the air is used to generate negative ions (a gaseous form of negative ion) during the ionization process. The remaining air generates other types of negative ions. This results in a low concentration of negative ions produced by the negative ion generator, reducing its bactericidal effect.

[0025] Furthermore, negative ions have a short lifespan and will gradually disappear if they are not delivered to the surrounding area in a timely manner. Therefore, negative ions need to be delivered to people's locations promptly. In related technologies, negative ion generators are usually located at the air outlet of the indoor unit. The airflow at the indoor unit's outlet can easily interfere with the movement of the ion air. For example, some air conditioners include a "wind avoids people" mode to ensure comfort and prevent the airflow from blowing directly on people. In this situation, it is even more difficult for negative ions to be delivered to the area around people, and a large number of negative ions will be transported to ineffective areas outside the people's location, easily wasting negative ions and reducing the air purification effect.

[0026] Furthermore, in related technologies, negative oxygen water ion generators are installed in a fixed manner, making it impossible to adjust the direction of ion delivery. They also cannot track changes in the position of the human body to achieve the effect of blowing ion winds onto people, nor can they automatically adjust the oxygen content in the room.

[0027] To address the aforementioned issues, some embodiments of the air conditioner disclosed herein provide an oxygen generator in the outdoor unit to supply oxygen to the negative oxygen ion generator, thereby increasing the oxygen content in the air surrounding the negative oxygen ion generator and thus improving the concentration of negative oxygen ions generated by the negative oxygen ion generator, thereby enhancing the sterilization effect of the air conditioner.

[0028] The negative ion generator is positioned beside the first air outlet to prevent interference from the air conditioning airflow. The negative ion generator is rotatably connected to the indoor unit to adjust the ion delivery direction.

[0029] The air conditioner in some embodiments of this disclosure is also equipped with an infrared sensor 4 to detect the location of people in the room, thereby enabling the delivery of ionized air or oxygen to the location of the people to ensure air purification effect.

[0030] Air conditioning equipment refers to devices that can regulate air. Its functions include cooling or heating the air, sterilizing and purifying it, and increasing oxygen concentration. Common air conditioning equipment includes air conditioners and air purifiers.

[0031] The following mainly uses air conditioners as an example to explain how to set up negative oxygen water ion generators in air conditioning equipment.

[0032] like Figure 1A and Figure 1B As shown, some embodiments of this disclosure provide an air conditioner 1000. The air conditioner 1000 includes an indoor unit 1, an outdoor unit 20, and a pipe 70. The indoor unit 1 and the outdoor unit 20 are connected through the pipe 70 to transmit refrigerant.

[0033] In some embodiments, the outdoor unit 20 includes a compressor 201 configured to compress a refrigerant such that a low-pressure refrigerant is compressed to form a high-pressure refrigerant.

[0034] In some embodiments, the outdoor unit 20 further includes an outdoor heat exchanger 203 configured to exchange heat between outdoor air and refrigerant transported within the outdoor heat exchanger 203. For example, in the cooling mode of the air conditioner 1000, the outdoor heat exchanger 203 operates as a condenser, causing the refrigerant compressed by the compressor 201 to dissipate heat to the outdoor air and condense through the outdoor heat exchanger 203. In the heating mode of the air conditioner 1000, the outdoor heat exchanger 203 operates as an evaporator, causing the depressurized refrigerant to absorb heat from the outdoor air and evaporate through the outdoor heat exchanger 203.

[0035] In some embodiments, the outdoor heat exchanger 203 includes heat exchange fins to increase the contact area between outdoor air and the refrigerant transported in the outdoor heat exchanger 203, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0036] In some embodiments, the outdoor unit 20 further includes an outdoor fan 204, which is configured to draw outdoor air into the outdoor unit 20 through the outdoor air inlet and to discharge the outdoor air, after heat exchange with the outdoor heat exchanger 203, through the outdoor air outlet. The outdoor fan 204 provides power for the flow of outdoor air.

[0037] In some embodiments, the indoor unit 1 includes an indoor heat exchanger 60. The indoor heat exchanger 60 is configured to exchange heat between indoor air and refrigerant transported within it. For example, in the cooling mode of the air conditioner 1000, the indoor heat exchanger 60 operates as an evaporator, causing the refrigerant, after being cooled by the outdoor heat exchanger 203, to absorb heat from the indoor air and evaporate through the indoor heat exchanger 60. In the heating mode of the air conditioner 1000, the indoor heat exchanger 60 operates as a condenser, causing the refrigerant, after absorbing heat by the outdoor heat exchanger 203, to dissipate heat to the indoor air and condense through the indoor heat exchanger 60.

[0038] In some embodiments, the indoor heat exchanger 60 includes heat exchange fins to increase the contact area between indoor air and the refrigerant transported in the indoor heat exchanger 60, thereby improving the heat exchange efficiency between the indoor air and the refrigerant.

[0039] like Figure 1A and Figure 1BAs shown, the indoor unit 1 also includes a first fan 30, which is configured to draw indoor air into the indoor unit 1 through the first air inlet 13 and to discharge the indoor air after heat exchange with the indoor heat exchanger 60 through the first air outlet 11 of the indoor unit 1. The first fan 30 provides power for the flow of indoor air.

[0040] In some embodiments, the outdoor unit 20 further includes an expansion valve 205 connected between the outdoor heat exchanger 203 and the indoor heat exchanger 60. The opening degree of the expansion valve 205 regulates the refrigerant pressure flowing through the outdoor heat exchanger 203 and the indoor heat exchanger 60, thereby regulating the refrigerant flow rate between the two units. The flow rate and pressure of the refrigerant flowing between the outdoor heat exchanger 203 and the indoor heat exchanger 60 will affect the heat exchange performance of the two units. The expansion valve 205 may be an electronic valve. The opening degree of the expansion valve 205 is adjustable to control the flow rate and pressure of the refrigerant flowing through it.

[0041] In some embodiments, a compressor 201, an outdoor heat exchanger 203, an expansion valve 205, and an indoor heat exchanger 60 connected in sequence form a refrigerant circuit. The refrigerant circulates in the refrigerant circuit and exchanges heat with the air through the outdoor heat exchanger 203 and the indoor heat exchanger 60, respectively, to achieve either a cooling mode or a heating mode for the air conditioner 1000. A four-way valve 202 is connected to the refrigerant circuit and is configured to switch the flow direction of the refrigerant in the refrigerant circuit so that the air conditioner 1000 executes either a cooling mode or a heating mode.

[0042] In some embodiments, reference Figure 2A The indoor unit 1 also includes a housing 10, in which an installation cavity is formed for housing components such as an indoor heat exchanger 60 and a first fan 30.

[0043] In some embodiments, the indoor unit 1 further includes a first air outlet 11. For example, the first air outlet 11 is disposed on the side of the housing 10 facing the user (such as the front side).

[0044] In some embodiments, the indoor unit 1 further includes a first air inlet 13. For example, the first air inlet 13 is disposed on the side of the housing 10 opposite to the side where the first air outlet 11 is located (such as the rear side).

[0045] Under the action of the first fan 30, indoor air flows through the first air inlet 13 to the indoor heat exchanger 60. After being cooled or heated by the indoor heat exchanger 60, it flows out from the first air outlet 11, thereby achieving the function of regulating the indoor air temperature.

[0046] In some embodiments, the indoor unit 1 further includes an air guide plate 12, which is disposed at the first air outlet 11. The air conditioner 1000 adjusts the flow direction of the air conditioning air blown out from the first air outlet 11 through the air guide plate 12. It should be noted that the air blown out through the first air outlet 11 is the air conditioning air. For example, the air conditioning air includes cold air, hot air, or outdoor fresh air.

[0047] In some embodiments, the air conditioner 1000 further includes a negative ion generator disposed in the indoor unit 1. The negative ion generator is configured to release negative ions into the indoor space 2.

[0048] Since most particulate matter in the air carries a positive charge, negative ions can combine with positively charged particles such as bacteria, dust, and smoke, causing these particles to become negatively charged. The negatively charged particles attract and aggregate with the positively charged particles, eventually settling down, thus purifying the air. Additionally, some particulate matter combines with negative oxygen ions to become negatively charged. Under the influence of an electric field, these negatively charged particles move towards a grounded object and eventually deposit on its surface, thus purifying the air.

[0049] In some embodiments, the negative ion generator is located at the first air outlet 11, and the negative ions are blown into the room with the air conditioning.

[0050] In some embodiments, the negative ion generator is located on the gas flow path between the first air outlet 11 and the first air inlet 13, and the negative ions are blown into the indoor space 2 with the airflow.

[0051] In some embodiments, the negative ion generator is a negative oxygen water ion generator 50, which is configured to release negative oxygen ions and nano water ions into the indoor space 2.

[0052] Negative oxygen ions have a good purifying effect on particulate matter and also have beneficial health effects such as promoting blood circulation and inhibiting disease development. The main component of nano-water ions is hydroxyl free radicals, which have a killing effect on bacteria and viruses.

[0053] In some embodiments, the negative oxygen water ion generator 50 is located beside the first air outlet 11, that is, the negative oxygen water ion generator 50 is not located inside the first air outlet 11. The direction adjustment of the air conditioning air blown out from the first air outlet 11 and the ion wind 3 blown out from the negative oxygen water ion generator 50 is independent of each other, that is, the air conditioning air and the ion wind 3 are controlled independently.

[0054] For example, the air conditioner 1000 can achieve "wind avoidance of people" by adjusting the air guide plate 12, that is, avoid the air conditioner air blowing directly on people and improve the comfort of air blowing.

[0055] The air conditioner 1000 adjusts the air outlet angle of the negative oxygen water ion generator 50 to achieve "wind blowing" of ion wind 3, so that the ion wind 3 blows near people and fully exerts the health benefits of negative oxygen ions on the human body.

[0056] In some embodiments, the negative oxygen water ion generator 50 can operate independently when the indoor unit 1 is turned off. For example, when the indoor temperature is suitable, there is no need to turn on the indoor unit 1 to adjust the indoor air temperature. In this case, only the negative oxygen water ion generator 50 can be turned on to provide nano water ions and negative oxygen ions to the room to improve indoor air quality.

[0057] In some embodiments, reference Figure 3 The indoor unit 1 also includes a third air duct 14, which connects the first air inlet 13 and the first air outlet 11. Indoor air enters the indoor unit 1 through the first air inlet 13 and enters the indoor space 2 through the third air duct 14 and the first air outlet 11. The third air duct 14 is the air duct through which the air conditioning air flows.

[0058] In some embodiments, reference Figure 3 The indoor unit 1 also includes a first air duct 400 (such as an air supply duct), which is configured to provide ionized air to the negative oxygen water ion generator 50. It should be noted that the air conditioning airflow duct is independently configured from the first air duct 400.

[0059] By setting the first air duct 400 of the negative oxygen water ion generator 50 independently from the third air duct 14, the negative oxygen water ion generator 50 can still be turned on to blow ions into the indoor space 2 when the indoor unit 1 is turned off.

[0060] In some embodiments, reference Figure 3 and Figure 4 The air inlet of the first air duct 400 is located on the air inlet side of the indoor heat exchanger 60, so that the air entering the first air duct 400 is air that has not been heated by the indoor heat exchanger 60, thus avoiding the effect of air temperature changes on the ionization effect of the negative oxygen water ion generator 50.

[0061] In some embodiments, reference Figure 5 The indoor unit 1 also includes a second fan 500 (such as an auxiliary fan). The second fan 500 is disposed within the first air duct 400 and is configured to provide airflow power within the first air duct 400 to increase the blowing distance of the ion wind 3.

[0062] In some embodiments, reference Figure 2B The indoor unit 1 also includes an infrared sensor 4, which is configured to detect the location of people in the room.

[0063] In some embodiments, the indoor unit 1 further includes a controller 8, which is coupled to an infrared sensor 4 and a second fan 500 to obtain the location information of people in the indoor space 2.

[0064] The controller 8 can be a chip or a processor. For example, the processor can be a general-purpose central processing unit (CPU), a microprocessor, or 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).

[0065] The controller 8 determines the distance D between the person and the air outlet based on the detection information from the infrared sensor 4. It should be noted that since the first air outlet 11 and the negative oxygen water ion generator 50 are both located on the front side of the indoor unit 1, the air outlet here can be either the air outlet for air conditioning or the air outlet for ionizing air.

[0066] The second fan 500 is selectively activated based on the relationship between D and the preset distance Dt, so that the ion wind 3 blown by the negative oxygen water ion generator 50 can reach the location of the person.

[0067] If it is determined that the distance D between the person and the first air outlet 11 is greater than or equal to the preset distance Dt, that is, when the person is far from the first air outlet 11, the second fan 500 is turned on to increase the blowing distance of the ion wind 3 and ensure that the ion wind 3 can be blown to the person.

[0068] If it is determined that the distance D between the person and the first air outlet 11 is less than the preset distance Dt, that is, when the person is close to the first air outlet 11, then the second fan 500 is turned off. Relying on the power of the first fan 30, positive pressure is generated inside the indoor unit 1, which also generates a certain airflow in the first air duct 400. Ions are blown to the person under the action of this airflow.

[0069] In some embodiments, the second fan 500 is a variable frequency fan. Since the speed of the variable frequency fan is adjustable, the accuracy of controlling the transmission distance of the ion wind 3 can be improved.

[0070] In some embodiments, controller 8 is further configured to: The infrared sensor 4 detects the spatial coordinates of the person's location in the room, and calculates the distance D between the person and the first air outlet 11 based on the coordinates.

[0071] The operating frequency of the second fan 500 is automatically adjusted based on the distance D. The operating frequency of the second fan 500 is positively correlated with the distance D. That is, the larger the distance D, the higher the operating frequency of the second fan 500; the smaller the distance D, the lower the operating frequency of the second fan 500.

[0072] Based on the location coordinates of the person, the rotation angle of the negative oxygen water ion generator 50 is controlled so that the ion wind 3 blows around the person.

[0073] Based on the distance between the person and the first air outlet 11, adjust the start / stop and rotation frequency of the second fan 500. In this way, not only can the ion wind 3 be blown around the person, but the air volume and speed of the ion wind 3 are also kept within the preset range to avoid excessive wind causing discomfort to the user.

[0074] In some embodiments, reference Figure 2B , Figure 5 and Figure 6 The outdoor unit 1 also includes an oxygen generator 5, which is configured to supply oxygen to the first air duct 400.

[0075] In this way, oxygen is supplied to the first air duct 400 by the oxygen generator 5, which increases the oxygen concentration in the air ionized by the negative oxygen water ion generator 50, thereby increasing the concentration of negative oxygen ions generated by the negative oxygen water ion generator 50 and improving the health and wellness effects on the human body.

[0076] In some embodiments, the air conditioner 1000 includes a cooling mode. When the cooling mode is activated, the air conditioner 1000 cools the indoor air.

[0077] In some embodiments, the air conditioner 1000 also includes a heating mode. When the heating mode is activated, the air conditioner 1000 heats the indoor air.

[0078] In some embodiments, the air conditioner 1000 also includes a health and wellness mode. When the health and wellness mode is activated, the negative oxygen water ion generator 50 is turned on, releasing negative oxygen ions and nano-water ions into the indoor space 2.

[0079] In some embodiments, the health and wellness mode includes an oxygen supply function. When the oxygen supply function is activated, the oxygen generator 5 is turned on to provide oxygen to the first air duct 400.

[0080] In some embodiments, the oxygen generator 5 is selectively turned on based on the indoor oxygen concentration.

[0081] In some embodiments, the indoor unit 1 further includes a first sensor 6. For example, the first sensor 6 is an oxygen concentration sensor, and the oxygen concentration sensor is disposed at the first air inlet 13. The first sensor 6 is configured to detect the oxygen concentration X at the first air inlet 13.

[0082] In some embodiments, the controller 8 is coupled to the first sensor 6 and the oxygen generator 5, and the controller 8 is further configured to: Obtain the oxygen concentration X at the first air inlet 13 detected by the first sensor 6.

[0083] If the oxygen concentration X is determined to be less than the first limit X1, it means that the oxygen concentration in the room is low. At this time, the oxygen generator 5 is turned on, and the high concentration of oxygen flows through the first air duct 400 to the emitting electrode 300 of the negative oxygen water ion generator 50, thereby increasing the concentration of negative oxygen ions generated by ionization.

[0084] If the oxygen concentration X is determined to be between the first limit X1 and the second limit X2, i.e. X1≤X<X2, it means that the oxygen concentration in the room is within a reasonable range. At this time, the oxygen generator 5 will continue to operate and supply oxygen to the room.

[0085] If the oxygen concentration X is determined to be greater than or equal to the second limit X2, it indicates that the oxygen concentration in the room is at a high level within a reasonable range. In this case, the oxygen concentrator 5 will be turned off, and the oxygen concentration in the room will gradually decrease. Afterward, if the oxygen concentration in the room decreases to X1 ≤ X < X2, the oxygen concentrator 5 will remain off. If the oxygen concentration in the room decreases to less than the first limit X1, the oxygen concentrator 5 will be turned on again, completing one cycle.

[0086] In some embodiments, reference Figure 5 The first air duct 400 includes a first sub-air duct 410, the air inlet of which is located on the air inlet side of the indoor heat exchanger 60. Air that has not been heated by the indoor heat exchanger 60 is supplied to the negative oxygen water ion generator 50 through the first sub-air duct 410.

[0087] It is understandable that the first sub-air duct 410 is independent of the third air duct 14, that is, the air conditioning air duct of the indoor unit 1. In this way, the air conditioning air and the ion air 3 can be controlled independently.

[0088] In some embodiments, the second fan 500 is disposed at the air inlet of the first sub-air duct 410. When the second fan 500 is turned on, it can increase the gas flow rate in the first sub-air duct 410, thereby increasing the delivery distance of the ions generated by the negative oxygen water ion generator 50.

[0089] In some embodiments, the first air duct 400 further includes a second sub-air duct 420, which is connected to the oxygen outlet of the oxygen generator 5 via a pipe. The air conditioner 1000 supplies oxygen to the second sub-air duct 420 through the oxygen generator 5, thereby increasing the oxygen concentration around the emitting electrode 300 of the negative oxygen water ion generator 50, increasing the concentration of negative oxygen ions generated by ionization, and thus helping to improve the oxygenation effect on the human body.

[0090] In some embodiments, reference Figures 7 to 14 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 heated by the indoor heat exchanger 60 can be supplied to the emitting electrode 300 of the negative oxygen water ion generator 50 via the first sub-air duct 410.

[0091] Structural reference of the emitting electrode 300 Figure 23 The emitting electrode 300 can be made of carbon fiber porous rod material containing a strong water-absorbing factor that can absorb moisture from the air and ionize water into nano water ions under high voltage conditions.

[0092] For example, the emitting electrode 300 includes a water-absorbing factor and a carbon fiber bundle. After the epoxy resin is cured, the carbon fiber bundle is carbonized at high temperature to form a porous carbon fiber rod structure. Through mechanical processing, one end is processed into a hemispherical emitting tip. After processing, the water-absorbing factor is impregnated into the interior of the carbon fiber bundle by ultrasonic impregnation to make a high-efficiency water-absorbing electrode.

[0093] In some embodiments, reference Figure 11 The negative oxygen water ion generator 50 also includes a negative high voltage power supply 600, which is configured to provide negative high voltage to the emitting electrode 300.

[0094] In some embodiments, reference Figure 7 The negative oxygen water ion generator 50 also includes a rotating part 100, which is configured to adjust the ion delivery direction. The emitting electrode 300 may be provided on the rotating part 100 so as to rotate with the rotating part 100.

[0095] In some embodiments, the rotating part 100 is configured to rotate within a first plane extending laterally, thereby driving the emitting electrode 300 to rotate within the first plane and adjusting the ion transport direction within the first plane. For example, the first plane is a horizontal plane.

[0096] In some embodiments, the rotating part 100 is configured to rotate within a vertically extending second plane to drive the emitting electrode 300 to rotate within the second plane, thereby adjusting the ion transport direction within the second plane. For example, the second plane is a vertical plane.

[0097] In some embodiments, the rotating part 100 is configured to rotate simultaneously in a first plane and a second plane, the first plane extending in a lateral direction and the second plane extending in a vertical direction, so as to adjust the transport direction of ions in three-dimensional space.

[0098] When the rotating part 100 rotates within the first plane (i.e., the horizontal plane), it drives the emitting electrode 300 to rotate within the horizontal plane, thereby achieving adjustment of ion transport in different directions within the horizontal plane. (Refer to...) Figure 12 The maximum rotatable angle of the rotating part 100 in the horizontal plane is a°.

[0099] When the rotating part 100 rotates within the second plane (i.e., the vertical plane), it drives the emitting electrode 300 to rotate within the vertical plane, thereby achieving adjustment of ion transport in different directions within the vertical plane. (Refer to...) Figure 13 The maximum rotatable angle of the rotating part 100 in the horizontal plane is b°.

[0100] In some embodiments, a second air duct 110 (such as an air duct) is formed within the rotating part 100. The second air duct 110 includes a second air inlet 150, which communicates with the first air duct 400. An emitting electrode 300 is disposed within the second air duct 110. This arrangement allows gas supplied by the first air duct 400 to flow into the second air duct 110 and make full contact with the emitting electrode 300. Thus, the emitting electrode 300 can fully ionize the air, improving the ionization effect.

[0101] In some embodiments, reference Figure 10 , Figure 11 , Figure 15 as well as Figure 16 The negative oxygen water ion generator 50 also includes an electrode mounting base 130. The electrode mounting base 130 is disposed in the second air duct 110 of the rotating part 100, and the emitting electrode 300 is inserted into the electrode mounting base 130.

[0102] In some embodiments, the second air duct 110 further includes a second air outlet 140, which is disposed on the rotating part 100, and ions generated by the emitting electrode 300 flow out from the second air outlet 140.

[0103] In some embodiments, the emitting tip of the emitting electrode 300 extends through the second air outlet 140 to facilitate ion diffusion.

[0104] In some embodiments, the gas in the second air duct 110 flows from the outer periphery of the electrode mounting base 130 to the second air outlet 140, so that the gas in the second air duct 110 surrounds the emitting tip of the emitting electrode 300, ensuring that the emitting tip is in full contact with the air and improving the ionization effect.

[0105] The emitting electrode 300 is placed in the second air duct 110. The gas flow rate in the second air duct 110 affects the ion transport speed. The gas flow rate in the second air duct 110 is controlled by the second fan 500, thereby controlling the ion transport distance and ensuring that the ions can be transported to the human body.

[0106] In some embodiments, the negative oxygen water ion generator 50 further includes a plurality of connecting ribs 120, and the electrode mounting base 130 is connected to the inner wall of the second air duct 110 through the plurality of connecting ribs 120, so as to realize the installation of the electrode mounting base 130 within the second air duct 110. The electrode mounting base 130 is aligned with the second air outlet 140 so that the emitting tip of the emitting electrode 300 is aligned with the second air outlet 140, thereby enabling the ions released by the emitting electrode 300 to flow out directly into the second air outlet 140.

[0107] A preset distance is spaced between the electrode mounting base 130 and the inner wall of the second air duct 110. This distance serves as a gap for gas flow, allowing the gas in the second air duct 110 to envelop the emission tip.

[0108] In some embodiments, the electrode mounting base 130 includes a mounting base body 135 and a mounting cavity 132. The mounting cavity 132 extends through the mounting base body 135. The rear end of the emitting electrode 300 is inserted into the mounting cavity 132 through a first end opening (such as a front opening) to fix it to the electrode mounting base 130. The emitting tip of the emitting electrode 300 extends from the mounting cavity 132, facing the second air outlet 140, so that the emitting tip is in full contact with the air, ensuring the smooth diffusion and escape of ions.

[0109] In some embodiments, reference Figure 11 The negative oxygen water ion generator 50 also includes a high-voltage line 160, one end of which is coupled to a negative high-voltage power supply 600, and the other end of which is coupled to an emitting electrode 300. The other end of the high-voltage line 160 is inserted into the mounting cavity 132 through the second end opening of the mounting cavity 132 to supply power to the emitting electrode 300.

[0110] In this way, the transmitting electrode 300 and the high-voltage line 160 are installed on the electrode mounting base 130 from different sides, which facilitates installation.

[0111] In some embodiments, the second air inlet 150 of the second air duct 110 is directly connected to the second air outlet 140, and the gas flowing in from the second air inlet 150 flows directly to the second air outlet 140 without turning. In this way, the air loss is small, and the narrow air duct has a certain acceleration effect on the airflow, which helps to increase the ion transport distance.

[0112] In some embodiments, the high-voltage line 160 extends into the mounting cavity 132 through the second air inlet 150 of the second air duct 110. In this way, the rotating part 100 does not need to be provided with a special wire hole for the high-voltage line 160, which facilitates the installation of the high-voltage line 160.

[0113] In some embodiments, reference Figure 10 , Figure 11 as well as Figure 15 The electrode mounting base 130 also includes a limiting part 131, which (such as a limiting step) is disposed on the inner wall of the mounting cavity 132.

[0114] The mounting cavity 132 includes a first sub-mounting cavity 1321 and a second sub-mounting cavity 1322. The first sub-mounting cavity 1321 is formed between the limiting part 131 and the first end opening of the mounting cavity 132, and the second sub-mounting cavity 1322 is formed between the limiting part 131 and the second end opening of the mounting cavity 132.

[0115] The electrode mounting base 130 also includes a connecting portion 133 (such as a groove), which is disposed on the inner wall of the mounting cavity 132 and passes through the first sub-mounting cavity 1321 and the second sub-mounting cavity 1322.

[0116] The rear end of the transmitting electrode 300 abuts against the limiting part 131, and the high voltage line 160 is inserted into the second sub-mounting cavity 1322.

[0117] It is understandable that when the transmitting electrode 300 is inserted into the mounting cavity 132, the transmitting electrode 300 is considered to be inserted in place when it abuts against the limiting part 131. The limiting part 131 is provided to limit the insertion distance of the transmitting electrode 300, ensuring that the transmitting electrodes 300 from different batches are inserted into the mounting cavity 132 to the same depth.

[0118] In some embodiments, the negative oxygen water ion generator 50 further includes conductive carbon paste 170. A portion of the conductive carbon paste 170 fills the second sub-mounting cavity 1322, and another portion of the conductive carbon paste 170 flows into the first sub-mounting cavity 1321 through the connecting portion 133 to encapsulate the emitting electrode 300.

[0119] It should be noted that the conductive carbon paste 170 is mainly composed of epoxy resin and carbon powder, and is conductive. On the one hand, the conductive carbon paste 170 serves to conduct electricity and fix the electrode, achieving coupling between the emitting electrode 300 and the high-voltage line 160. The conductive carbon paste 170 also serves to fix the emitting electrode 300.

[0120] Since the emitting electrode 300 contains water-absorbing factors, if the high-voltage line 160 directly contacts the emitting electrode 300 after the emitting electrode 300 absorbs water, the copper wire of the high-voltage line 160 will lose electrons under negative high-voltage conditions, and thus undergo electrochemical corrosion. Therefore, by using conductive carbon paste 170 to achieve coupling between the emitting electrode 300 and the high-voltage line 160, direct contact between the emitting electrode 300 and the high-voltage line 160 can be avoided, thereby preventing electrochemical corrosion of the copper wire of the high-voltage line 160.

[0121] On the other hand, the conductive carbon paste 170 also serves a fixing function. Another portion of the conductive carbon paste 170 flows into the first sub-mounting cavity 1321 through the connecting part 133, which can wrap around the emitting electrode 300. This helps to further improve the conductivity of the negative oxygen water ion generator 50 and is beneficial to improving the fixing effect on the emitting electrode 300.

[0122] In some embodiments, the installation process of the emitting electrode 300 includes: One end of the high-voltage line 160 is exposed to expose the internal copper wire, for example, 5mm to 8mm.

[0123] The exposed copper wire end is inserted into the second sub-mounting cavity 1322 from the second end opening of the mounting cavity 132.

[0124] The conductive carbon paste 170 is poured into the second sub-mounting cavity 1322 from the first open end of the mounting cavity 132, so that the conductive carbon paste 170 wraps the copper wire. After the conductive carbon paste 170 is poured in, it should be above the height of the limiting part 131, and a part of the conductive carbon paste 170 enters the first sub-mounting cavity 1321.

[0125] 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 limiting part 131. During the insertion of the emitting electrode 300, the conductive carbon paste 170 is squeezed and the conductive carbon paste 170 wraps around the root of the emitting electrode 300 to enhance conductivity.

[0126] After installation, allow it to stand for a period of time, such as 24 hours, until the conductive carbon paste 170 is completely cured. At this time, the emitting electrode 300 is securely installed in the mounting cavity 132.

[0127] In some embodiments, the working principle of the negative oxygen water ion generator 50 includes: the negative high voltage power supply 600 transmits high voltage through the high voltage line 160 to the conductive carbon paste 170, and then to the carbon fiber electrode of the emitting electrode 300. The carbon fiber electrode contains a large number of water-absorbing factors and can directly absorb moisture from the air. The carbon fiber electrode is composed of countless carbon fibers arranged in sequence, and the end of each carbon fiber is equivalent to an emitting tip. Therefore, the electrode end is designed with a large number of emitting tips to ionize the water in the electrode and the oxygen in the air, generating nano water ions rich in hydroxyl radicals and high concentrations of negative oxygen ions, which are discharged into the air from the second air outlet 140 to purify pollutants such as microorganisms, particulate matter, and volatile organic compounds (VOCs) in the indoor space 2, thereby increasing the oxygen content of the indoor air.

[0128] In some embodiments, reference Figure 11 and Figure 16 The electrode mounting base 130 also includes an air guide surface 134, which is disposed on the outer wall of the end of the mounting base body 135 facing the second air inlet 150 of the second air duct 110, so as to play the role of air guiding and reduce airflow resistance and noise.

[0129] In some embodiments, the negative oxygen water ion generator 50 further includes a mounting part 200, and the rotating part 100 is mounted on the indoor unit 1 via the mounting part 200.

[0130] It is understandable that the mounting part 200 serves as the mounting carrier for the rotating part 100, enabling a rotatable connection with the rotating part 100.

[0131] For example, refer to Figure 7 and Figure 17 The mounting portion 200 includes a mounting portion body 230 and a first mating portion 212. The mounting portion body 230 includes a mounting space 240, which is configured to mount the rotating portion 100. The first mating portion 212 is provided on the side wall of the mounting portion body 230 that forms the mounting space 240. For example, the first mating portion 212 is provided on the inner wall of two opposing side walls of the mounting portion body 230.

[0132] The rotating part 100 includes a rotating part body 111 and a second mating part 190. The second mating part 190 is disposed on the outer wall of the rotating part body 111. The first mating part 212 engages with the second mating part 190 to rotatably clamp the rotating part 100 within the mounting space 240.

[0133] In some embodiments, the outer contour of the rotating part 100 is spherical, and two first mating parts 212 are provided and arranged opposite to each other. The first mating parts 212 are concave, and their concave contours are adapted to the spherical contours of the rotating part 100. In this way, it is possible to achieve clamping with the rotating part 100 while ensuring the rotation of the rotating part 100.

[0134] In some embodiments, the mounting portion 200 includes two first mounting arms 210 arranged at a distance from each other, forming a mounting space 240 between the two first mounting arms 210. A first mating portion 212 is provided on the sidewall of either of the two first mounting arms 210 facing the mounting space 240. The first mating portion 212 is provided on opposite sides of each of the two first mounting arms 210. In this way, the mounting portion 200 clamps the rotating portion 100 from opposite sides, improving the reliability of the clamping structure.

[0135] In some embodiments, the mounting portion 200 further includes two extensions 211. The two extensions 211 are respectively disposed at one end of the two first mounting arms 210 near the rotating portion 100 and extend downward. A first mating portion 212 is disposed on the side of either of the two extensions 211 near the rotating portion 100.

[0136] The extension 211 has a preset volume, providing a sufficiently large setting and forming space for the first mating part 212, increasing the area of ​​the first mating part 212, and helping to improve the clamping reliability of the rotating part 100.

[0137] In some embodiments, the mounting portion 200 further includes a second mounting arm 220 connected between the two first mounting arms 210. For example, the second mounting arm 220 is connected to the end of the two first mounting arms 210 away from the rotating portion 100 so as not to interfere with the mounting of the rotating portion 100.

[0138] In some embodiments, the negative oxygen water ion generator 50 further includes a drive unit 700, which is configured to drive the rotating unit 100 to rotate in three-dimensional space to adjust the ion delivery direction.

[0139] The drive unit 700 is configured to drive the rotating unit 100 to rotate within at least one of a first plane or a second plane to adjust the ion delivery direction. In some embodiments, the first plane is defined as a horizontal plane and the second plane as a vertical plane.

[0140] For example, the drive unit 700 is configured to drive the rotating unit 100 to rotate in a horizontally extending first plane, thereby adjusting the transport direction of ions in the first plane.

[0141] The drive unit 700 is configured to drive the rotating unit 100 to rotate in a vertically extending second plane, thereby adjusting the transport direction of ions in the second plane.

[0142] The drive unit 700 is configured to drive the rotating unit 100 to rotate simultaneously in a first plane and a second plane, the first plane extending in the lateral direction and the second plane extending in the vertical direction, so as to adjust the transport direction of ions in three-dimensional space.

[0143] In some embodiments, reference Figure 7 , Figure 8 as well as Figure 10 The drive unit 700 includes a first sub-drive unit 710, the power output shaft of which is connected to the rotating unit 100. The first sub-drive unit 710 is configured to drive the rotating unit 100 to rotate in a first plane extending in the lateral direction.

[0144] In some embodiments, the first sub-drive unit 710 is a horizontal stepper motor, and the motor shaft of the motor is connected to the rotating unit 100.

[0145] In some embodiments, a first sub-drive unit 710 is provided on the top of the rotating part 100. The power output shaft of the first sub-drive unit 710 is directly opposite the center of the sphere of the rotating part 100.

[0146] In some embodiments, reference Figure 19 The first sub-drive unit 710 includes a first sub-drive unit body 715, a power output shaft 716, and a locking part 711 (such as a rectangular body). For example, the locking part 711 is provided at one end of the power output shaft 716 and is machined into a rectangular body. The locking part 711 is provided with a first pin hole 712.

[0147] Reference Figure 18 The rotating part 100 also includes a first mounting member 180. The first mounting member 180 is disposed on the top of the rotating part body 111, and a mounting hole 181 (such as a rectangular mounting hole) is provided on the first mounting member 180. A second pin hole 182 is provided on the side wall of the mounting hole 181. The snap-fit ​​part 711 is inserted into the mounting hole 181, and the pin passes through the first pin hole 712 and the second pin hole 182 to fix the snap-fit ​​part 711 into the mounting hole 181, thereby realizing the fixed installation of the first sub-drive part 710 and the rotating part 100.

[0148] Understandably, referring to Figure 12 The power output shaft of the first sub-drive unit 710 rotates, causing the rotating unit 100 to rotate in the horizontal plane.

[0149] In some embodiments, the drive unit 700 further includes a second sub-drive unit 720, which is fixedly disposed on the mounting unit 200. For example, the second sub-drive unit 720 is fixedly disposed on the second mounting arm 220.

[0150] The drive unit 700 also includes a transmission link assembly 730, which is disposed between the power output shaft of the second sub-drive unit 720 and the first sub-drive unit 710. The second sub-drive unit 720 is configured to drive the rotating unit 100 to rotate in a second plane extending in the vertical direction.

[0151] For example, the second sub-drive unit 720 is a vertical stepper motor, and the motor shaft of the motor is connected to the transmission link assembly 730.

[0152] The transmission linkage assembly 730 includes a first link 731 and a second link 732, which are rotatably connected. One end of the first link 731 is rotatably connected to the first sub-drive unit 710. One end of the second link 732 is fixedly connected to the power output shaft of the second sub-drive unit 720.

[0153] Reference Figure 13 The second sub-drive unit 720 rotates, and through the transmission action of the first link 731 and the second link 732, it drives the first sub-drive unit 710 to move. The first sub-drive unit 710 then transmits the force to the rotating unit 100, thereby realizing the rotation of the rotating unit 100 in the vertical plane. Figure 14 The rotation posture of the rotating part 100 at various different angular positions is shown.

[0154] In some embodiments, reference Figure 8 and Figure 20 The first sub-drive unit 710 also includes a second mounting member 713, which is disposed on the side of the first sub-drive unit body 715 near the second sub-drive unit 720.

[0155] In some embodiments, the second mounting member 713 includes a second mounting member body 717 and a mounting shaft 714. The mounting shaft 714 is disposed on the side of the second mounting member body 717 near the second sub-drive portion 720, and one end of the first connecting rod 731 is rotatably connected to the mounting shaft 714.

[0156] In some embodiments, the drive unit 700 is located above the rotating unit 100, which facilitates the access of the first air duct 400, high-voltage line 160, etc. from below the second mounting arm 220 into the rotating unit 100.

[0157] In some embodiments, the rotation of the rotating part 100 in the horizontal direction is controlled by the first sub-drive unit 710, and the rotation of the rotating part 100 in the vertical direction is controlled by the second sub-drive unit 720. The two directions can be adjusted simultaneously, and the adjustments in the two directions do not affect each other, which helps to improve the adjustment efficiency.

[0158] In some embodiments, the negative oxygen water ion generator 50 includes a control component 800, which includes a main control board, a microcontroller unit (MCU), a first sub-control component 801, and a second sub-control component 802. The first sub-control component 801 controls the rotation of the first sub-drive unit 710, and the second sub-control component 802 controls the rotation of the second sub-drive unit 720. By controlling the rotation angles of the first sub-drive unit 710 and the second sub-drive unit 720, the rotation direction and angle of the rotating unit 100 are controlled.

[0159] For example, the operation of the negative oxygen water ion generator 50 includes: The equipment is powered on.

[0160] The main control board detects whether the current position of the first sub-drive unit 710 and the second sub-drive unit 720 is the initial position state. If yes, it proceeds to the next step. If no, the MCU will send a signal to the first sub-control component 801 and the second sub-control component 802 to adjust the first sub-drive unit 710 and the second sub-drive unit 720 to the initial default state.

[0161] The main control board receives the location information that the ions need to be delivered to.

[0162] The main control board transmits the position information to the MCU. The MCU converts the position signal into the rotation signal required by the first sub-drive unit 710 and the second sub-drive unit 720, and issues commands to the first sub-control component 801 and the second sub-control component 802. The first sub-control component 801 and the second sub-control component 802 control the corresponding motors to rotate by a preset angle. The first sub-drive unit 710 drives the rotating unit 100 to rotate in the horizontal direction, while the second sub-drive unit 720 drives the rotating unit 100 to rotate in the vertical direction.

[0163] Each of the above-mentioned position information directly corresponds to the rotation angle of the first sub-drive unit 710 and the second sub-drive unit 720 through a logic algorithm, until the second air outlet 140 is directly facing the target position, so as to ensure that the ions are delivered to the target position.

[0164] The control process of the rotating part 100 is simple and efficient. The external input position signal is directly converted into the rotation angle signal of the first sub-drive part 710 and the second sub-drive part 720 through a logic algorithm, and then applied to the rotating part 100.

[0165] In some embodiments, to control the accuracy of position orientation, the number of steps of the stepper motors of the first sub-drive unit 710 and the second sub-drive unit 720 within the rotation angle limit range can be appropriately increased, thereby increasing the matching points of the horizontal and vertical stepper motors and improving the resolution. For example, if both the horizontal and vertical stepper motors can be divided into 7 steps within the angle limit range, a total of 49 position points can be placed. If the number of steps of the horizontal and vertical stepper motors within the angle limit range is increased to 10 steps, a total of 100 position points can be placed, and the corresponding position accuracy will be significantly improved. Here, the horizontal stepper motor refers to the first sub-drive unit 710, and the vertical stepper motor refers to the second sub-drive unit 720.

[0166] In some embodiments, the air supply pipe connected to the rotating part 100 is a flexible pipe to accommodate the rotation of the rotating part 100.

[0167] In some embodiments, reference Figure 25 The negative oxygen water ion generator 50 includes either a directional delivery mode or a purging mode.

[0168] In directional delivery mode, the rotating part 100 is held at a set angle position to deliver ions in a directional manner. In directional delivery mode, the driving part 700 drives the rotating part 100 to rotate at a corresponding angle according to the target position information, so that the second air outlet 140 is directly facing the target position, thereby enabling the blown ion wind 3 to reach the target position directly.

[0169] In purge mode, the rotating part 100 reciprocates within a set plane to deliver ions in a purge manner within the set plane.

[0170] The purging mode includes at least one of the following: horizontal purging mode, vertical purging mode, or 3D purging mode.

[0171] In horizontal purging mode, the rotating part 100 reciprocates within a first plane extending in the lateral direction to deliver ions in a purging manner within the first plane. For example, the first sub-drive unit 710 drives the rotating part 100 to reciprocate within the first plane, such as... Figure 12 As shown, taking a horizontal plane as an example, this demonstrates how ions are swept horizontally.

[0172] In vertical purging mode, the rotating part 100 reciprocates within a second plane extending vertically to deliver ions in a purging manner within the second plane. For example, the second sub-drive unit 720 drives the rotating part 100 to reciprocate within the second plane, such as... Figure 13 As shown. Taking the second plane as the vertical plane as an example, the ion purging in the vertical direction is realized.

[0173] In 3D purging mode, the rotating part 100 reciprocates within a first plane and a second plane to deliver ions in different directions within three-dimensional space. For example, the first sub-drive unit 710 and the second sub-drive unit 720 operate simultaneously, driving the rotating part 100 to reciprocate within both the first and second planes. Taking a horizontal plane as the first plane and a vertical plane as an example, this enables the delivery of ions in different directions within the room.

[0174] In some embodiments, controller 8 is further configured to: When indoor unit 1 is turned on for the first time, the dimensions of the indoor space 2 where indoor unit 1 is located and the installation location information of indoor unit 1 are obtained. The dimensions of indoor space 2 include the dimensions of indoor space 2, the dimensions of doors and windows, and the location information of doors and windows.

[0175] Based on the collected size information of the indoor space 2 where the indoor unit 1 is located and the installation location information of the indoor unit 1, three-dimensional spatial coordinate points are laid out in the indoor space 2 to form a three-dimensional spatial matrix.

[0176] The first rotation angle value A of the first sub-drive unit and the second rotation angle value B of the second sub-drive unit of the negative oxygen water ion generator 50 corresponding to the three-dimensional coordinate points in the three-dimensional spatial matrix are determined, and the correspondence between the three-dimensional coordinate points and the first rotation angle value A and the second rotation angle value B is stored.

[0177] Activate infrared sensor 4 to obtain the number of people in indoor space 2 and the target three-dimensional spatial coordinates of the people in indoor space 2.

[0178] Based on the acquired target three-dimensional spatial coordinates and the correspondence between the stored three-dimensional coordinate points and the first rotation angle value A and the second rotation angle value B, the first rotation angle value and the second rotation angle value are determined, and the first drive unit and the second drive unit are controlled to operate according to the first rotation angle value and the second rotation angle value, so as to blow the ion wind to the target position (i.e. the target three-dimensional spatial coordinates where the indoor personnel are located).

[0179] Understandably, when the indoor unit 1 is turned on for the first time, the controller 8 obtains the size information of the indoor space 2 where the indoor unit 1 is located and the installation position information of the indoor unit 1, forming a three-dimensional spatial matrix. The controller 8 determines the rotation range of the rotating part 100 based on the three-dimensional spatial matrix.

[0180] For example, the controller 8 converts any one of the three-dimensional coordinate points in the three-dimensional spatial matrix into a first rotation angle A in the horizontal plane and a second rotation angle B in the vertical plane of the rotating part 100 based on the position of the three-dimensional spatial matrix and the indoor unit 1, and stores the mapping relationship between the any one three-dimensional coordinate point and the first rotation angle A and the second rotation angle B.

[0181] Reference Figure 1C Upon initial power-on, the controller 8 acquires and saves information such as the room dimensions and the location of the indoor unit 1. It then decomposes this information into a three-dimensional spatial coordinate system at specific dimensional intervals, forming a three-dimensional spatial matrix. Each point in the matrix corresponds to a three-dimensional spatial coordinate. Based on the relative position of these three-dimensional spatial coordinates to the air conditioner, the controller 8 converts each coordinate into horizontal and vertical rotation angles for the rotating part 100, thereby enabling ion delivery to any location within the indoor space 2.

[0182] This method pre-calculates and saves the turning angles of the first sub-drive unit 710 and the second sub-drive unit 720 corresponding to each coordinate position in the room, which greatly improves the processing speed of the controller 8 in converting three-dimensional position information into motor control signals for the negative oxygen water ion generator 50 during actual use, and improves the stability of the air conditioner 1000.

[0183] In some embodiments, the infrared sensor 4 is also configured to detect the number of people in the room.

[0184] The controller 8 determines the three-dimensional spatial coordinates of the person based on the detection information of the infrared sensor 4, retrieves the mapping value to control the rotation position of the rotating part 100, and enables the negative oxygen water ion generator 50 to deliver ions to the location of the person.

[0185] The infrared sensor 4 detects the number of people in the room and their pre-saved three-dimensional coordinates, tracks human movement, and adjusts the rotation position of the rotating part 100 to directly deliver negative oxygen ions to the area around the human body.

[0186] In some embodiments, reference Figure 1C and Figure 24 When the indoor unit 1 is turned on for the first time, the controller 8 obtains the room size and the location of the indoor unit 1, and saves this information. The controller 8 then performs three-dimensional spatial coordinate decomposition at certain size intervals (e.g., 0.3-1m) to form a three-dimensional spatial matrix that matches the actual room. Any point in the matrix corresponds to a three-dimensional spatial coordinate.

[0187] The controller 8 converts each coordinate into a mapping value of the turning angle A and B of the rotating part 100 of the negative oxygen water ion generator 50 in the horizontal and vertical directions according to the relative position relationship between the three-dimensional coordinates and the indoor unit 1. When the spatial position coordinates of the local space exceed the maximum turning limit of the rotating part 100, the maximum turning angle is used and saved, so that the ion wind 3 can blow towards the target area as much as possible.

[0188] Subsequently, when indoor unit 1 is turned on, controller 8 activates infrared sensor 4 to detect the location of people in the room and their three-dimensional spatial coordinates.

[0189] The controller 8 retrieves the previously stored horizontal and vertical motor rotation angles A and B under the three-dimensional coordinate position conditions, and controls the first sub-drive unit 710 and the second sub-drive unit 720 to operate in place, thereby quickly and efficiently blowing negative oxygen ions to the fixed coordinate position.

[0190] In some embodiments, reference Figure 26 The working process of air conditioner 1000 in "health and wellness mode" includes S301 to S310.

[0191] Understandably, when indoor unit 1 is turned on, the air conditioner outlet will perform either cooling or heating functions according to the user's selection. The user can choose to turn on "health and wellness mode" according to their needs. After it is turned on, the negative oxygen water ion generator 50 will start working.

[0192] The user selects whether to start the oxygen supply function. If the user selects to start the oxygen supply function, the first sensor 6 first detects the oxygen concentration X at the first air inlet 13.

[0193] When the oxygen concentration is lower than the first limit X1, the controller 8 turns on the oxygen generator 5. High-concentration oxygen flows into the second air duct 110 of the rotating part 100 through the first sub-air duct 410, and is ionized into negative oxygen ions by the emission electrode 300 and then sent into the room air.

[0194] When the oxygen concentration X satisfies X1≤X<X2, it means that the oxygen concentration in the room is within a reasonable range. At this time, the oxygen generator 5 will continue to operate and supply oxygen to the room.

[0195] When the oxygen concentration X≥X2, it means that the oxygen concentration in the room has reached a high value within a reasonable range. At this time, the controller 8 controls the oxygen generator 5 to be turned off. After the oxygen generator 5 is turned off, the oxygen concentration in the room will gradually decrease. When it decreases to X1≤X<X2, the oxygen generator 5 will still remain in operation. Only when it is lower than the first limit X1 will the controller 8 turn the oxygen generator 5 back on, thus completing one cycle.

[0196] In some embodiments, reference Figure 26 The working process of air conditioner 1000 under "health and wellness mode" also includes S311 to S323.

[0197] After the negative oxygen water ion generator 50 starts working, the infrared sensor 4 first determines the number of people N in the room.

[0198] When N=1, the infrared sensor 4 detects the position of the person in the room, that is, determines the three-dimensional coordinate system (the position of the head). The controller 8 calculates the rotation angle of the rotating part 100 in the horizontal and vertical directions based on the person's coordinates, so that the ion wind 3 blows around the human body.

[0199] At the same time, the controller 8 calculates the distance D between the person and the first air outlet 11 based on the personnel position coordinates detected by the infrared sensor 4. When D ≥ preset distance Dt, it means that the person is far away from the first air outlet 11. The power provided by the first fan 30 is no longer sufficient to meet the needs of long-distance ion transmission. At this time, the controller 8 controls the second fan 500 to be turned on, providing power to the second air duct 110 of the negative oxygen water ion generator 50, increasing the blowing speed of the ion wind 3, and thus enabling the negative oxygen ions to be blown to a more distant target location.

[0200] When D < preset distance Dt, it means that the personnel are close to the first air outlet 11 and the power provided by the first fan 30 is sufficient to meet the ion transport distance requirement. Therefore, the second fan 500 is turned off at this time.

[0201] At each interval T2, the infrared sensor 4 detects the location coordinates of the people in the room again, and readjusts the blowing angle of the ion wind 3 and the start of the second fan 500 based on the latest location.

[0202] When N > 1, the controller 8 uses the infrared sensor 4 to detect the number of people N in the indoor space 2 and the position coordinates M of each person, and automatically calculates the distance D1, D2, D3...DN of each person from the first air outlet 11.

[0203] The controller 8 automatically arranges the personnel positions in order of proximity from near to far, and then controls the rotation angle of the rotating part 100 in the horizontal and vertical directions, and controls the ion wind 3 to start blowing from the nearest personnel position to the farthest position. The blowing time for each position is t3, until the blowing of each personnel position is completed.

[0204] During the purging process, the controller 8 determines the distance D between the personnel and the first air outlet 11. When D ≥ the preset distance Dt, the second fan 500 is turned on. After one cycle, the second fan 500 is turned off.

[0205] After the first purging is completed, the controller 8 controls the infrared sensor 4 to immediately reconfirm the coordinates of the personnel in the indoor space 2, and rearrange the distances of each person from the first air outlet 11: D1, D2, D3...DN.

[0206] According to the latest arrangement, the controller 8 controls the negative oxygen water ion generator 50 to purge again and turns on the second fan 500 when appropriate.

[0207] It should be noted that because negative ion generators have a dust-reducing effect, some of the settled dust particles may adhere to the walls during use, potentially causing the walls around the generator to darken, resulting in the "black wall phenomenon." Understandably, the higher the concentration of negative ions produced by the generator, the stronger its purification ability, and the more pronounced the "black wall phenomenon."

[0208] Understandably, the negative oxygen ion generator 50 releases negative oxygen ions and nano-water ions into the air. Near the emitting tip of the emitting electrode 300, the concentration of negative oxygen ions is high. Some of these ions easily adhere to the surface of the wall or casing around the emitting electrode 300, causing some airborne dust particles to adhere to this surface, resulting in the "black wall phenomenon." Additionally, some particulate matter combines with negative oxygen ions to become negatively charged. Under the influence of an electric field, these negatively charged particles move towards a grounded object and eventually deposit on its surface. Over time, this accumulation of particles creates the "black wall phenomenon" around the emitting electrode 300.

[0209] In some embodiments, reference Figure 2A The housing 10 of the air conditioner 1000 includes a housing body 101 and a front panel 102. The front panel 102 is located on the side of the housing body 101 closest to the user (i.e., the front side). A first air outlet 11 is located on the front panel 102.

[0210] In some embodiments, the housing 10 further includes a panel 40 disposed on one side of the front panel 102. A negative ion generator 50 is disposed on the panel 40. For example, the panel 40 is made of plastic.

[0211] In some embodiments, reference Figure 22 The panel 40 includes a panel body 43 and an opening 41. The opening 41 is disposed on the panel body 43, and one end of the negative oxygen water ion generator 50 extends out of the opening 41. The opening 41 is connected to the second air outlet 140 of the rotating part 100. The emitting electrode 300 extends out through the second air outlet 140 and the opening 41, so that the ions released by the emitting electrode 300 flow into the indoor space 2 without obstruction, which facilitates the escape and diffusion of ions.

[0212] It should be noted that the panel 40 and the front side panel 102 can be separate structures, which facilitates the assembly of the panel 40 with the negative oxygen water ion generator 50. Alternatively, the panel 40 and the front side panel 102 can be integrally molded, which simplifies the installation process and improves installation efficiency.

[0213] In some embodiments, the panel 40 further includes a clearance portion 44 disposed at the circumferential edge of the panel body 43 near the opening 41. For example, the clearance portion 44 is a tapered surface.

[0214] In some embodiments, the avoidance portion 44 extends toward the shell body 101 (i.e., from front to back) to prevent one end of the negative oxygen water ion generator 50 from extending out of the panel body 43, thereby protecting the negative oxygen water ion generator 50 from being bumped or damaged.

[0215] In some embodiments, the inner diameter of the clearance portion 44 is reduced along the direction toward the shell body 101, thereby allowing the clearance portion 44 to make way for the rotation of the rotating portion 100, avoiding obstruction of ion diffusion, and facilitating the escape and diffusion of ions.

[0216] It should be noted that although panel 40 is not directly grounded, when the air humidity is high or the air conditioner 1000 is in cooling mode, causing condensation on the surface of panel 40, panel 40 is in close contact with the air conditioner's grounding sheet metal, so panel 40 is also equivalent to a weak ground terminal. Therefore, after long-term use, a "black wall phenomenon" will appear on panel 40, causing panel 40 to become dirty.

[0217] In some embodiments of this disclosure, panel 40 contains metallic conductive particles, and negative high-voltage power supply 600 supplies negative electricity to panel 40, making panel 40 negatively charged. On the one hand, negative oxygen ions generated by negative oxygen water ion generator 50 are repelled by panel 40 and moved away from panel 40, thereby inhibiting negative ions from adhering to panel 40 and avoiding the "black wall phenomenon". On the other hand, negatively charged particulate matter in the air that combines with negative oxygen ions is repelled by panel 40 and moved away from panel 40, thereby preventing negatively charged particulate matter from depositing on panel 40 and avoiding the "black wall phenomenon" of panel 40.

[0218] It should be noted that panel 40 is a plastic part. Metal conductive particles are added to the plastic particles that are injection molded into panel 40 to increase the conductivity of panel 40 without affecting its color.

[0219] In some embodiments, the negative high voltage power supply 600 provides negative high voltage to the panel 40, so that a large number of negative charges are distributed on the panel 40. When negatively charged particles in the air approach the panel 40, they are repelled by the panel 40, which is also negatively charged, causing the negatively charged particles to move away from the panel 40, thereby depositing the negatively charged particles onto the panel 40.

[0220] Reference Figure 21 The negative high-voltage power supply 600 includes a first negative high-voltage power supply line 610 and a second negative high-voltage power supply line 620. The first negative high-voltage power supply line 610 is configured to supply power to a negative ion generator (e.g., a negative oxygen water ion generator 50). The second negative high-voltage power supply line 620 is configured to supply power to the panel 40.

[0221] For example, the first negative high-voltage power supply line 610 provides a negative high-voltage range of -3000V to -6000V. The second negative high-voltage power supply line 620 provides a negative high-voltage range of -500V to -2000V.

[0222] In some embodiments, a protective resistor is provided at the high voltage output terminal of the negative high voltage power supply 600. The negative oxygen water ion generator 50 has a small design power of only 1W. When a person accidentally touches the emitting electrode 300 or the panel 40, the current flowing through the human body is in the microampere level, so it will not have an adverse effect on the human body.

[0223] In some embodiments, a terminal block 42 is provided on the panel 40, and a second negative high-voltage power supply line is connected to the terminal block 42 to supply negative power to the panel 40.

[0224] In some embodiments, reference Figure 2A and Figure 2B The indoor unit 1 also includes a second sensor 7 (such as a distance sensor), which is configured to detect the distance between a person and the panel 40. When the distance between the person and the panel 40 is less than a set value, the negative high-voltage power supply 600 stops supplying power.

[0225] It should be noted that since both the negative oxygen water ion generator 50 and the panel 40 are electrically charged, although the electricity generated by the negative oxygen water ion generator 50 and the panel 40 will not cause harm to the human body, there will still be a slight momentary electric shock when a person touches them.

[0226] In some embodiments, the air conditioner 1000 includes an adjustment button disposed on the housing 10. For example, the adjustment button is disposed on the panel 40. The air conditioner 1000 also includes an "adjustment mode," see reference... Figure 27 The operation process of the "debugging mode" of air conditioner 1000 includes S401 to S404.

[0227] Understandably, once the adjustment button is turned on, the air conditioner 1000 will enter "adjustment mode". In "adjustment mode", after the adjustment personnel select to turn on the purification function, the negative oxygen water ion generator 50 and the panel 40 will be powered on immediately to facilitate the adjustment personnel to check the operating status of the air conditioner 1000.

[0228] Reference Figure 27 After debugging is completed and "Debug Mode" is turned off, controller 8 is also configured to execute S405 to S407.

[0229] Understandably, when the indoor unit 1 is in use after debugging, the second sensor 7 detects the distance between the person and the panel 40. When the distance between the person and the panel 40 is less than the set value (e.g., 1m), the negative high voltage power supply 600 stops supplying power, that is, the negative oxygen water ion generator 50 and the panel 40 are de-energized, thereby avoiding the user from experiencing an electric shock discomfort when touching the emitting electrode 300 or the panel 40.

[0230] If it is determined that the distance between the person and the panel 40 is greater than the set value, the negative high voltage power supply 600 will supply power to the negative oxygen water ion generator 50 and the panel 40 again.

[0231] Some embodiments of this disclosure also provide a control method for an air conditioner 1000, which can be executed by a controller 8 or the air conditioner 1000.

[0232] In some embodiments, reference Figure 24 The method includes steps S101 to S105.

[0233] S101, upon first power-on of indoor unit 1, acquire the dimension information of the indoor space 2 where indoor unit 1 is located and the installation location information of indoor unit 1. The dimension information of indoor space 2 includes the shape and size of indoor space 2, the size of doors and windows, and the location information of doors and windows.

[0234] S102, based on the collected size information of the indoor space 2 and the installation position information of the indoor unit 1, three-dimensional spatial coordinate points are arranged in the indoor space 2 to form a three-dimensional spatial matrix. The three-dimensional spatial matrix includes at least one three-dimensional coordinate point.

[0235] S103, determine the first rotation angle value A of the first sub-drive unit and the second rotation angle value B of the second sub-drive unit of the negative oxygen water ion generator 50 corresponding to any three-dimensional coordinate point in at least one three-dimensional coordinate point in the three-dimensional space matrix, and store the correspondence between the any three-dimensional coordinate point and the first rotation angle value A and the second rotation angle value B.

[0236] S104, activate infrared sensor 4 to obtain the location of people indoors and the target three-dimensional spatial coordinates of the people indoors.

[0237] S105. Based on the acquired target three-dimensional spatial coordinates and the mapping relationship between the stored three-dimensional coordinate points and the first rotation angle value A and the second rotation angle value B, determine the target first rotation angle value and the target second rotation angle value, and control the first drive unit and the second drive unit to operate according to the target first rotation angle value and the target second rotation angle value, so as to blow the ion wind to the target position (i.e. the target three-dimensional spatial coordinates where the indoor personnel are located).

[0238] In some embodiments, reference Figure 25 The method includes steps S201 to S211.

[0239] S201, start the air conditioner 1000 and control the air conditioner 1000 to operate according to the cooling mode, heating mode or fresh air mode selected by the user, and deliver cold air, hot air or outdoor fresh air from the first air outlet 11.

[0241] S203 receives the ion wind purging mode selected by the user.

[0242] S204, if the user selects the directional delivery mode, then execute S205.

[0243] S205 allows users to adjust the rotation angles of the horizontal and vertical stepper motors according to the required position, which then act on the rotating part. The motor stops when it reaches the desired position, thus enabling directional ion delivery in a fixed direction.

[0244] S206, if the user selects the horizontal purging mode, then execute S207.

[0245] S207 controls the vertical stepper motor to be in the initial default position and controls the horizontal stepper motor to reciprocate within the range of the maximum swing angle a°, thereby realizing the sweeping of negative oxygen ions in the horizontal direction.

[0246] S208, if the user selects the vertical purge mode, then execute S209.

[0247] S209 controls the horizontal stepper motor to be in the initial default position and controls the vertical stepper motor to reciprocate within the range of the maximum swing angle b°, thereby realizing the blowing of negative oxygen ions in the vertical direction.

[0248] S210, if the user selects the 3D blowing mode, then execute S211.

[0249] S211 controls the horizontal and vertical stepper motors to reciprocate simultaneously within the range of maximum swing angles a° and b°, thereby delivering ions in different directions within the room.

[0250] In some embodiments, reference Figure 26 The method includes steps S301 to S311.

[0251] S301, start the air conditioner 1000 and control the air conditioner 1000 to operate according to the cooling mode, heating mode or fresh air mode selected by the user, and deliver cold air, hot air or outdoor fresh air from the first air outlet 11.

[0258] S308, determine if X satisfies: X≥X2. If yes, execute S309; ​​otherwise, execute S310.

[0259] S309, shut down oxygen concentrator 5. Then re-execute S305.

[0260] S310, the state of oxygen concentrator 5 remains unchanged.

[0261] S311, the number of people N in the indoor space 2 is detected by infrared sensor 4.

[0262] S312, determine if N satisfies: N > 1. If yes, execute S313; otherwise, execute S316.

[0263] S313, using infrared sensor 4 to detect the position coordinates M of any one of the N people in the indoor space 2, and calculate the distances D1, D2, D3...DN of the person from the air conditioner vent.

[0264] S314, arrange the position coordinates of the personnel in order of distance from near to far, and then control the first drive unit and the second drive unit to rotate, so that the ion wind blows from the position coordinates of the closest personnel to the position coordinates of the farthest personnel.

[0265] S315, during the purging process, if it is determined that D > Dt, then the second fan 500 is turned on, and after one purging cycle is completed, the second fan 500 is turned off.

[0266] S316 uses infrared sensor 4 to detect the location coordinates of people in indoor space 2.

[0267] S317 determines the rotation angle of the first and second drive units based on the coordinates of the personnel's location, so that the ion wind blows around the human body.

[0268] S318, calculate the distance D between the person and the first air outlet 11 based on the coordinates of the person's location.

[0269] S319, determine if D satisfies: D > Dt. If yes, execute S320; otherwise, execute S321.

[0270] S320, turn on the second fan 500 to increase the delivery distance of the ion wind.

[0271] S321, the interval is set to a preset duration T2, and S316 is executed again.

[0272] S322, shut down the second fan 500.

[0273] S323, the interval is set to a preset duration T2, and S316 is executed again.

[0274] In some embodiments, after the air conditioner 1000 is installed, it also needs to be debugged. (Refer to...) Figure 27 The method includes steps S401 to S404.

[0275] S401, if the controller 8 receives a debugging command, a password input interface will be displayed on the control panel 9 or mobile terminal.

[0276] S402, if the password entered by the commissioning personnel is confirmed to be correct, the commissioning mode is entered. In commissioning mode, the commissioning personnel can check the operating status of the air conditioner 1000 in different operating modes. For example, the commissioning personnel can check the operating status of the air conditioner 1000 in cooling mode, heating mode, or purification mode.

[0277] S403, in the debugging mode, if it is determined that the debugging personnel have turned on the "health and wellness mode", the negative oxygen water ion generator 50 and the panel 40 will be powered on so that the debugging personnel can check the static electricity of the negative oxygen water ion generator 50 and the panel 40.

[0278] S404: If a debug end command is received, debug mode will be turned off.

[0279] Continue to refer to Figure 27 If the user restarts the "Health and Wellness Mode" after debugging is completed, the method also includes S405 to S407.

[0280] S405, when the debugging mode is off, if it is determined that the user has turned on the "health and wellness mode", the second sensor 7 is turned on to obtain the distance between the user and the air conditioning panel 40, and power is supplied to the negative oxygen water ion generator 50.

[0281] S406 If it is determined that the distance between the user and the panel 40 is less than the preset distance, the power to the negative oxygen water ion generator 50 is cut off to prevent accidental contact by personnel.

[0282] S407 If it is determined that the distance between the user and the panel 40 is greater than or equal to the preset distance, the power supply to the negative oxygen water ion generator 50 is restored, and the negative oxygen water ion generator 50 restarts operation.

[0284] Those skilled in the art will understand that the scope of this invention is not limited to the specific embodiments described above, and that modifications and substitutions can be made to certain elements of the embodiments without departing from the spirit of this application. The scope of this application is limited by the appended claims.
