[0038] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0039] Considering that oxygen-generating air conditioners have certain health-care effects on special groups (such as the elderly, children, and people with poor cardiopulmonary function, etc.), compared with conventional air conditioners and fresh air air conditioners, they can quickly achieve high-precision oxygen concentration control; Figure 6 The following is a schematic diagram of the change curve of indoor air oxygen content after different air conditioners have been running for different periods of time. Figure 6 As shown in the figure, different air conditioners have different oxygen contents in the indoor air after running for different periods of time. Indoor air quality adjustment requires fresh air mode. For example, when a baby defecates indoors, indoor air pollution requires fresh air ventilation. However, oxygen-generating air conditioners and fresh air air conditioners are set separately, and it is impossible to accurately adjust the indoor air quality to improve indoor comfort.

[0040] Therefore, the scheme of the present invention proposes a control method for an air conditioner, specifically a control method for a fresh air oxygen-generating air conditioner, which has a separate fresh air ventilation mode, a separate oxygen production adjustment mode and a dynamic oxygen production (i.e., fresh air + oxygen production) mode, and can quickly refresh and enrich the indoor air quality; the dynamic oxygen production is dynamically regulated according to the numerical relationship between the set oxygen content, the indoor oxygen content and the outdoor oxygen content, which can effectively improve the regulation of indoor air oxygen content parameters and freshness, and enhance indoor comfort.

[0041] According to an embodiment of the present invention, a method for controlling an air conditioner is provided. Figure 1A flow chart of an embodiment of the method of the present invention is shown. The air conditioner has an air compressor, a diverter valve, an oxygen production module, a fresh air outlet of the indoor unit and an oxygen outlet of the indoor unit; the diverter valve has a first flow path and a second flow path; the output end of the air compressor is connected to the fresh air outlet of the indoor unit through the first flow path to realize the fresh air function of the air conditioner, and is connected to the oxygen outlet of the indoor unit through the second flow path and the oxygen production module to realize the oxygen production function of the air conditioner; the scheme of the present invention provides a new type of air conditioner with fresh air and oxygen production functions, which not only has conventional cooling and heating functions, but also has a separate fresh air function, a separate oxygen production function and a dynamic oxygen production function. Therefore, in addition to the air conditioning components of a conventional air conditioner, the air conditioner also includes components related to the fresh air function and the oxygen production function. Figure 7 This is a structural diagram of a new type of fresh air oxygen-generating air conditioner indoor unit layout. Figure 7 As shown, the indoor unit of the air conditioner is designed with a fresh air outlet and an oxygen outlet. In related schemes, the power source of the fresh air air conditioner is generally the indoor fan, and the power source of the oxygen-making air conditioner is the air compressor and is located outdoors; there are problems of multiple and scattered power sources, and the energy consumption is high when both are turned on at the same time. In the scheme of the present invention, the fresh air and oxygen-making functions share a set of power equipment, namely the air compressor, so that the two functional modules of oxygen-making and fresh air are combined, the power equipment is reduced, and the overall structural size is reduced. In the scheme of the present invention, by merging the power sources of the fresh air function and the oxygen-making function, the number of components is reduced, the utilization rate of components is improved, and the energy consumption of air conditioning is reduced.

[0042] In some embodiments, the air conditioner has an indoor unit air outlet; the indoor unit fresh air outlet and / or the indoor unit oxygen outlet are both located on the side wall of the indoor unit air outlet of the air conditioner; Figure 7 As shown, preferably, the fresh air outlet and oxygen outlet of the indoor unit of the air conditioner are located on the side of the air duct, which is convenient for mixing with the air conditioning airflow and improving the comfort of air supply. In the scheme of the present invention, the specific setting positions of the indoor unit fresh air outlet and the indoor unit oxygen outlet can be flexibly set according to the convenience of use. Preferably, the indoor unit fresh air outlet circulates separately and is located at the top of the indoor unit of the air conditioner; the indoor unit oxygen outlet is located on the side of the air duct, specifically on the side of the air outlet section of the bottom shell of the indoor unit of the air conditioner, which is convenient for pipe routing. At the same time, the indoor oxygen concentration can be quickly adjusted with the help of the large air volume circulation of the indoor fan of the air conditioner.

[0043] In some embodiments, a filtering device and / or a dehumidifying device is provided at the input end of the air compressor, so that outdoor air passes through the filtering device and / or the dehumidifying device before entering the air compressor, which is beneficial to improving the cleanliness of the air finally input into the room, and can also prevent impurities and moisture in the outdoor air from damaging the air compressor, thereby helping to protect the air compressor itself.

[0044] In some embodiments, a muffler is provided between the first flow path and the fresh air outlet of the indoor unit.

[0045] Figure 8 This is a schematic diagram of the structure of a new type of fresh air oxygen air conditioner outdoor unit layout. Figure 8 As shown, the outdoor unit of the present invention is composed of a conventional air conditioner outdoor unit + the distribution area of ​​the fresh air and oxygen production module of the present invention. In the scheme of the present invention, the fresh air and oxygen production related parts include power equipment, oxygen production molecular sieve, filter device, dehumidification device, buffer oxygen storage device, diverter valve, muffler, flow control valve, environmental temperature sensor, one-way valve, fresh air pipe, etc.

[0046] like Figure 8 As shown, the air conditioner outdoor unit is designed with a high layer on the top of the conventional outdoor unit. The high layer is used for oxygen-related parts of the molecular sieve oxygen production module, including power equipment, oxygen molecular sieve, filter device, dehumidification device, buffer oxygen storage device, diverter valve, muffler, flow control valve, environmental temperature sensor, one-way valve, etc. Preferably, the power equipment is an oil-free air compressor to ensure sufficient power and clean and fresh air compressed by it. Preferably, 2 or more molecular sieves are used for oxygen molecular screening to ensure oxygen supply and concentration.

[0047] In the related schemes, the fresh air function and the oxygen production function are controlled separately, lacking dynamic synergy. However, the scheme of the present invention uses oxygen concentration detection equipment to switch between oxygen production and fresh air modes, achieving dynamic oxygen production with coordinated control and adjusting the air freshness. In the scheme of the present invention, the fresh air function and the oxygen production function are controlled by a diverter valve, which reduces the exhaust gas discharge of the air compressor, improves its work efficiency, and realizes dynamic regulation of the fresh air volume and oxygen production volume.

[0048] In some embodiments, the oxygen production module includes: a molecular sieve oxygen production tower four-way valve, a first oxygen production tower, a second oxygen production tower, and a buffer oxygen storage device; the second flow path first passes through the molecular sieve oxygen production tower four-way valve, then passes through the first oxygen production tower and the second oxygen production tower respectively, and then passes through the buffer oxygen storage device to connect to the indoor unit oxygen outlet. Preferably, a first one-way valve such as one-way valve 1 is provided between the second flow path and the molecular sieve oxygen production tower four-way valve, and a second one-way valve such as one-way valve 2 is provided at the input end of the buffer oxygen storage device to ensure the one-way flow of air and avoid waste caused by backflow.

[0049] Fig. 9 The schematic diagram is a structural diagram of a new type of fresh air oxygen-generating air conditioning component association system. Fig. 9 In the example shown, compared with the structure of related solutions, the fresh air fan is reduced and the air compressor is used directly, so the fresh air volume is larger and the indoor ventilation efficiency is improved; the diverter valve dynamically adjusts the oxygen and fresh air flow to achieve rapid indoor air renewal and oxygen concentration adjustment. Fig. 9 As shown, an oxygen concentration detector is designed on the housing of the filter device for outdoor oxygen concentration detection and for the control of relevant dynamic oxygen production schemes of the air conditioner. The temperature sensing package is located on the air compressor, mainly monitoring the temperature at the outlet of the air compressor to prevent the system temperature from being too high. Preferably, the diverter valve is an electronically controlled diverter valve, which can adjust the left and right openings according to the preset logic of the detection data, and the diverter valve has a real-time flow monitoring function, which calculates the flow on the left and right sides respectively, and feeds back to the controller in real time. Preferably, a muffler is connected in series between the diverter valve and the fresh air outlet of the indoor unit to reduce wind noise and transmission sound.

[0050] exist Fig. 9 In the example shown, the filter device and the dehumidification device are connected to the pipeline where the air compressor is located in turn; the pipeline where the air compressor is located is divided into two routes after passing through the diverter valve: one route is connected to the fresh air outlet of the indoor unit after passing through the muffler, and the other route is connected to the first valve port of the molecular sieve oxygen tower four-way valve after passing through the one-way valve 1. The second valve port of the molecular sieve oxygen tower four-way valve is connected to the first end of the one-way valve 2 after passing through the oxygen tower 2, the third valve port of the molecular sieve oxygen tower four-way valve is connected to the nitrogen exhaust port, and the fourth valve port of the molecular sieve oxygen tower four-way valve is connected to the first end of the one-way valve 2 after passing through the oxygen tower 1. The second end of the one-way valve 2 is connected to the oxygen outlet of the indoor unit after passing through the buffer oxygen storage device.

[0051] In the related schemes, the oxygen production control process lacks consideration of the oxygen content of the outdoor environment, and the indoor oxygen content regulation scheme is relatively simple, and the comfort is poor. In the scheme of the present invention, dynamic oxygen production is dynamically regulated according to the numerical relationship between the set oxygen content, indoor oxygen content and outdoor oxygen content, which can effectively improve the regulation of indoor air oxygen content parameters and freshness. In the scheme of the present invention, through the dynamic regulation of the fresh air volume and oxygen production volume, a large flow of oxygen-enriched air and a small flow of high-oxygen air are obtained, which improves the comfort of indoor oxygen content parameter regulation.

[0052] In the scheme of the present invention, Figure 1 As shown, the air conditioner control method includes: steps S110 to S140.

[0053] In step S110, after the air conditioner is started, the oxygen adjustment mode of the air conditioner is determined; the oxygen adjustment mode of the air conditioner includes: any one of a single oxygen production mode, a single fresh air mode, and a mixed oxygen production and fresh air mode.

[0054] At step S120, according to the determined oxygen regulation mode of the air conditioner, the air compressor is controlled to start, the opening and closing and the opening degree of at least one of the first flow path and the second flow path are controlled, and the oxygen production module is controlled to start in the single oxygen production mode or the oxygen production and fresh air mixed mode, so that the air conditioner runs the oxygen regulation mode of the air conditioner.

[0055] In some embodiments, in step S120, according to the oxygen adjustment mode of the air conditioner determined, the air compressor is controlled to start, the opening and closing and the opening degree of at least one of the first flow path and the second flow path are controlled, and the oxygen production module is controlled to start in the single oxygen production mode or the oxygen production and fresh air mixed mode, including any of the following start-up control situations:

[0056] The first startup control scenario: if it is determined that the oxygen adjustment mode of the air conditioner is the separate oxygen production mode, the first flow path is controlled to be closed, the second flow path is controlled to be opened and the opening degree is controlled to be the set maximum opening degree, the air compressor is controlled to start, and when the oxygen production module includes a molecular sieve oxygen production tower four-way valve, the molecular sieve oxygen production tower four-way valve is controlled to start.

[0057] The second startup control scenario: if it is determined that the oxygen adjustment mode of the air conditioner is the separate fresh air mode, the first flow path is controlled to be opened and the opening degree is the set maximum opening degree, the second flow path is controlled to be closed, and the air compressor is controlled to start.

[0058] The third startup control scenario: if it is determined that the oxygen adjustment mode of the air conditioner is the oxygen production and fresh air mixed mode, the first flow path is controlled to be opened and the opening degree is the set maximum opening degree, the second flow path is controlled to be opened and the opening degree is the set maximum opening degree, the air compressor is controlled to start, and when the oxygen production module includes a molecular sieve oxygen production tower four-way valve, the molecular sieve oxygen production tower four-way valve is controlled to start.

[0059] Fig.10 The figure is a flowchart of the start-up status of components and their control methods in different modes. Fig.10 As shown, the start-up status of the start-up components and their control methods in different modes include:

[0060] Step 1: After the air conditioner is started, the operation mode is determined, and then step 2, step 3, step 4, or step 5 is executed. Preferably, the operation mode is mainly selected by the user and does not involve active startup. Fig.10 As shown, the operating modes are divided into four categories, including conventional cooling or heating mode, oxygen production mode, fresh air mode, and fresh air + oxygen production mode. Preferably, the latter three modes can be entered by the user through autonomous selection under the condition that the conventional cooling or heating mode is started. The main function of the air conditioner is cooling and heating. Whether the user turns on the fresh air or oxygen production function can be selectively turned on by the remote control, application (Application, App), voice, etc., which is called the autonomous selection process.

[0061] Step 2: If only cooling or heating mode is entered, the air conditioner starts normally, and other components do not start.

[0062] Step 3: If the oxygen production mode is started or entered, the right side of the diverter valve is opened to the maximum and the left side is closed; the air compressor is started; the oxygen molecular sieve oxygen production tower four-way valve is started; and the oxygen production mode is entered. In this way, when the user turns on the oxygen production mode, the maximum opening is used to produce oxygen, and the set oxygen concentration can be quickly reached.

[0063] Step 4: If the fresh air mode is started or entered, the left side of the diverter valve is opened to the maximum and the right side is closed; the air compressor is started; and the fresh air mode is entered. In this way, when the user turns on the fresh air mode, the fresh air is delivered at the maximum opening, which can quickly achieve indoor air renewal.

[0064] Step 5: If the fresh air + oxygen production mode is started or entered, the dynamic oxygen production mode is entered. In this way, in the fresh air + oxygen production mode, the indoor oxygen concentration is dynamically adjusted to achieve rapid adjustment of indoor air freshness.

[0065] In the scheme of the present invention, the oxygen production function and the fresh air function are jointly applied and coordinated controlled on the air conditioner, with a reversing valve, a fresh air function, no fresh air fan, and an emergency mode. The two functional modules of oxygen production and fresh air are combined to reduce power equipment and reduce the overall structure size. At the same time, the oxygen concentration detection equipment is used to switch the oxygen production and fresh air modes to achieve coordinated control of dynamic oxygen production and adjust the air freshness.

[0066] At step S130, when the air conditioner is operated in the oxygen adjustment mode of the air conditioner, an indoor oxygen content parameter of the air conditioner is obtained, and an outdoor oxygen content parameter of the air conditioner is obtained.

[0067] At step S140, the air compressor is controlled to continue running or stop in combination with the indoor oxygen content parameter of the air conditioner, the outdoor oxygen content parameter of the air conditioner, and the set oxygen content parameter, the opening of the second flow path is controlled in the oxygen production and fresh air mixed mode, and the oxygen production module is controlled to continue running or stop in the oxygen production mode alone or the oxygen production and fresh air mixed mode, so as to adjust the oxygen content parameter and / or freshness of the indoor air of the air conditioner and improve indoor comfort.

[0068] The control scheme of a fresh air oxygen-generating air conditioner provided by the solution of the present invention is a scheme that has both fresh air and oxygen-generating functions and can dynamically adjust the fresh air volume and oxygen production volume, thereby quickly adjusting the indoor air quality. In the solution of the present invention, an air conditioner with both fresh air and oxygen-generating functions is provided, and the fresh air and oxygen-generating functions share a set of power equipment, namely, an air compressor; three operating modes can be realized, namely, a separate fresh air ventilation mode, a separate oxygen production adjustment mode, and a dynamic oxygen production (i.e., fresh air + oxygen production) mode, which can quickly refresh and enrich the indoor air quality; dynamic oxygen production is dynamically regulated according to the numerical relationship between the set oxygen content, the indoor oxygen content, and the outdoor oxygen content, which can effectively improve the adjustment of indoor air oxygen content parameters and freshness, and improve indoor comfort.

[0069] In some embodiments, step S140 combines the indoor oxygen content parameter of the air conditioner, the outdoor oxygen content parameter of the air conditioner, and the set oxygen content parameter to control the air compressor to continue running or stop, control the opening of the second flow path in the oxygen production and fresh air mixed mode, and control the oxygen production module to continue running or stop in the oxygen production mode alone or the oxygen production and fresh air mixed mode, including: the process of adjusting the oxygen content parameter in the oxygen production mode alone.

[0070] Combine the following Figure 2 The flowchart of an embodiment of the process of adjusting the oxygen content parameters in the oxygen production mode alone in the method of the present invention is shown, which further illustrates the specific process of adjusting the oxygen content parameters in the oxygen production mode alone in step S140, including: step S210 to step S230.

[0071] Step S210: If it is determined that the oxygen adjustment mode of the air conditioner is the independent oxygen production mode, it is determined whether the indoor oxygen content parameter of the air conditioner reaches the set oxygen content parameter.

[0072] Step S220: If it is determined that the indoor oxygen content parameter of the air conditioner does not reach the set oxygen content parameter, the first flow path is maintained closed, the second flow path is maintained open and the opening is the set maximum opening. If the oxygen production module includes a molecular sieve oxygen production tower four-way valve, the molecular sieve oxygen production tower four-way valve is controlled to continue to operate, and the air compressor is controlled to continue to operate.

[0073] Step S230: If it is determined that the indoor oxygen content parameter of the air conditioner has reached the set oxygen content parameter, then when the oxygen production module includes a molecular sieve oxygen production tower four-way valve, the molecular sieve oxygen production tower four-way valve is controlled to shut down, and the air compressor is controlled to shut down and the diverter valve is closed.

[0074] like Fig.10As shown, the start-up status of components in different modes and their control methods also include: in step 3, if the oxygen production mode is started or entered, the right side of the diverter valve is opened to the maximum and the left side is closed; the air compressor is started; the four-way valve of the oxygen production molecular sieve oxygen production tower is started; and the oxygen production mode is entered. As oxygen is continuously produced, the indoor oxygen concentration increases, and the set oxygen concentration and the indoor detected oxygen concentration are compared synchronously: if the indoor oxygen concentration reaches the set oxygen concentration, the oxygen production molecular tower and the air compressor are shut down, and the diverter valve is closed (that is, no air passes) to avoid excessive oxygen concentration, resulting in oxygen intoxication or other safety accidents; if it is not reached, it continues to run. In this way, when the user turns on the oxygen production mode, the maximum opening oxygen production can quickly reach the set oxygen concentration, and dynamically adjust to accurately control the indoor oxygen content parameters and improve indoor comfort.

[0075] In some embodiments, step S140 combines the indoor oxygen content parameter of the air conditioner, the outdoor oxygen content parameter of the air conditioner, and the set oxygen content parameter to control the air compressor to continue running or stop, control the opening of the second flow path in the oxygen production and fresh air mixed mode, and control the oxygen production module to continue running or stop in the oxygen production mode alone or the oxygen production and fresh air mixed mode, and also includes: a process of adjusting the oxygen content parameter in the fresh air mode alone.

[0076] Combine the following Figure 3 The flowchart of an embodiment of the process of adjusting the oxygen content parameters in the fresh air mode alone in the method of the present invention further illustrates the specific process of adjusting the oxygen content parameters in the fresh air mode alone in step S140, including: step S310 to step S330.

[0077] Step S310: If it is determined that the oxygen adjustment mode of the air conditioner is the fresh air mode alone, it is determined whether the indoor oxygen content parameter of the air conditioner reaches the set oxygen content parameter.

[0078] Step S320: If it is determined that the indoor oxygen content parameter of the air conditioner does not reach the set oxygen content parameter, the first flow path is maintained open and the opening is the set maximum opening, the second flow path is maintained closed, and the air compressor is controlled to continue to operate.

[0079] Step S330: If it is determined that the indoor oxygen content parameter of the air conditioner has reached the set oxygen content parameter, the air compressor is controlled to stop and the diverter valve is closed.

[0080] like Fig.10As shown, the start-up status of components in different modes and their control methods also include: in step 4, if the fresh air mode is started or entered, the left side of the diverter valve is opened to the maximum and the right side is closed; the air compressor is started; and the fresh air mode is entered. With the continuous introduction of fresh air for ventilation, the indoor air quality is improved, and the set oxygen concentration and the oxygen concentration detected indoors are compared synchronously: if the indoor oxygen concentration reaches the set oxygen concentration, indicating that the overall indoor air renewal is completed, the air compressor is shut down and the diverter valve is closed (that is, no air passes); if it is not reached, it continues to run. Preferably, the set oxygen concentration = outdoor oxygen concentration. In this way, when the user turns on the fresh air mode, the maximum opening fresh air delivery can quickly realize indoor air renewal, and dynamically adjust to accurately control the indoor oxygen content parameters and improve indoor comfort.

[0081] In some embodiments, in step S140, the air compressor is controlled to continue to run or stop in combination with the indoor oxygen content parameter of the air conditioner, the outdoor oxygen content parameter of the air conditioner, and the set oxygen content parameter, the opening of the second flow path is controlled in the oxygen production and fresh air mixed mode, and the oxygen production module is controlled to continue to run or stop in the oxygen production mode alone or the oxygen production and fresh air mixed mode, and further includes: if it is determined that the oxygen adjustment mode of the air conditioner is the fresh air mode alone, then after the air compressor is turned on or the air compressor continues to run: if it is determined that the indoor oxygen content parameter of the air conditioner is greater than If the outdoor oxygen content parameter of the air conditioner is determined, the air compressor is controlled to continue running until it is determined that the indoor oxygen content parameter of the air conditioner has reached the set oxygen content parameter, and the air compressor is controlled to stop and the diverter valve is closed; and / or, if it is determined that the oxygen adjustment mode of the air conditioner is the separate fresh air mode, when it is determined that the indoor oxygen content parameter of the air conditioner has reached the set oxygen content parameter, the air compressor is controlled to stop and the diverter valve is closed for a set time period; wherein the set time period is the ratio of the space size parameter of the room where the air conditioner is located to the fresh air flow parameter in the separate fresh air mode.

[0082] like Fig.10As shown, the start-up status of the components in different modes and the control method thereof also include: in step 4, in addition, if the indoor oxygen concentration is detected to be higher than the outdoor oxygen concentration during the fresh air start-up stage, the fresh air is still running, and the fresh air stop condition is still that the indoor oxygen concentration reaches the set oxygen concentration; that is, when the user uses the oxygen production function to raise the oxygen concentration, after using it for a period of time, the oxygen concentration needs to be adjusted back to the normal concentration, so as to avoid no shutdown reference value when the fresh air is running. If the indoor oxygen concentration is detected to be = the set oxygen concentration during the fresh air start-up stage, the stop time of the fresh air operation is a certain time period t, and the time period t = room space size / fresh air flow rate; wherein the room space size is input by the user when installing the air conditioner, and the fresh air flow rate is the real-time flow rate provided by the diverter. In this way, the fresh air stop time is adjusted according to the indoor oxygen concentration to achieve indoor air safety regulation and avoid oxygen intoxication or excessive oxygen concentration. Under high oxygen concentration conditions, in order to avoid oxygen intoxication or other high oxygen concentration conditions caused by the discomfort, fresh air input is required for air conditioning.

[0083] In some embodiments, step S140 combines the indoor oxygen content parameter of the air conditioner, the outdoor oxygen content parameter of the air conditioner, and the set oxygen content parameter to control the air compressor to continue running or stop, control the opening of the second flow path in the oxygen production and fresh air mixed mode, and control the oxygen production module to continue running or stop in the single oxygen production mode or the oxygen production and fresh air mixed mode, and also includes: a process of adjusting the oxygen content parameter in the oxygen production and fresh air mixed mode.

[0084] Combine the following Figure 4 The flowchart of an embodiment of the process of adjusting the oxygen content parameters in the oxygen production and fresh air mixing mode in the method of the present invention is shown, which further illustrates the specific process of adjusting the oxygen content parameters in the oxygen production and fresh air mixing mode in step S140, including: step S410 to step S460.

[0085] Step S410: If it is determined that the oxygen adjustment mode of the air conditioner is the oxygen production and fresh air mixed mode, the relationship between the set oxygen content parameter, the outdoor oxygen content parameter of the air conditioner, and the indoor oxygen content parameter of the air conditioner is determined.

[0086] Step S420: If it is determined that the outdoor oxygen content parameter of the air conditioner is greater than the indoor oxygen content parameter of the air conditioner and less than the set oxygen content parameter, the opening of the second flow path is controlled to be a first set opening, and then it is determined whether the indoor oxygen content parameter of the air conditioner is equal to the set oxygen content parameter.

[0087] Step S430, if it is determined that the indoor oxygen content parameter of the air conditioner is greater than the outdoor oxygen content parameter of the air conditioner and less than the set oxygen content parameter, the opening of the second flow path is controlled to be a second set opening, and then it is determined whether the indoor oxygen content parameter of the air conditioner is equal to the set oxygen content parameter; the upper limit of the second set opening is less than the lower limit of the first set opening.

[0088] Step S440, if it is determined that the set oxygen content parameter is greater than the outdoor oxygen content parameter of the air conditioner and less than the indoor oxygen content parameter of the air conditioner, the opening of the second flow path is controlled to be a third set opening, and then it is determined whether the indoor oxygen content parameter of the air conditioner is equal to the set oxygen content parameter; the upper limit of the third set opening is less than the lower limit of the second set opening.

[0089] Step S450, if it is determined that the indoor oxygen content parameter of the air conditioner is not equal to the set oxygen content parameter, the first flow path is maintained open and the opening is the set maximum opening, the second flow path is maintained open and the opening is the set maximum opening, and when the oxygen production module includes a molecular sieve oxygen production tower four-way valve, the molecular sieve oxygen production tower four-way valve is controlled to continue to operate, and the air compressor is controlled to continue to operate, and then return to re-determine the relationship between the set oxygen content parameter, the outdoor oxygen content parameter of the air conditioner, and the indoor oxygen content parameter of the air conditioner.

[0090] Step S460: If it is determined that the indoor oxygen content parameter of the air conditioner is equal to the set oxygen content parameter, then when the oxygen production module includes a molecular sieve oxygen production tower four-way valve, the molecular sieve oxygen production tower four-way valve is controlled to shut down, and the air compressor is controlled to shut down and the diverter valve is closed.

[0091] like Fig.10 As shown, the start-up status of components in different modes and their control methods also include: in step 5, if the fresh air + oxygen production mode is started or entered, the dynamic oxygen production mode is entered. The operation of this mode is related to the oxygen concentration, including the set oxygen concentration, indoor oxygen concentration, and outdoor oxygen concentration. It should be noted that the oxygen concentration in the general living area of ​​humans is 20.9%. Under normal circumstances, the indoor oxygen concentration is lower than the outdoor oxygen concentration due to various consumptions (such as human breathing, equipment oxygen consumption, etc.) without additional oxygen addition. Therefore, for air conditioners with oxygen production function, the set value of oxygen concentration, that is, the set oxygen concentration, is generally not less than the outdoor oxygen concentration. Therefore, the following three situations occur:

[0092] The first case: set oxygen concentration> outdoor oxygen concentration> indoor oxygen concentration; then the right opening of the diverter valve is [80%; 100%].

[0093] The second situation: set oxygen concentration>indoor oxygen concentration>outdoor oxygen concentration; right side opening of the diverter valve [60%; 80%).

[0094] The third situation: indoor oxygen concentration > set oxygen concentration > outdoor oxygen concentration; right side opening of the diverter valve [0%; 20%).

[0095] As dynamic oxygen production proceeds, indoor air quality improves, and the set oxygen concentration is compared with the oxygen concentration detected indoors: if the indoor oxygen concentration reaches the set oxygen concentration, it means that the overall indoor quality has met the set requirements, and the air compressor stops; if it does not meet the requirements, it continues to run. In this way, in the fresh air + oxygen production mode, the indoor oxygen concentration is dynamically adjusted to achieve rapid adjustment of indoor air freshness, and dynamic adjustment is performed to accurately control indoor oxygen content parameters and improve indoor comfort.

[0096] By adopting the technical solution of this embodiment, a set of air compressors is provided for the oxygen production function and the fresh air function of the air conditioner, so that the air compressor is connected to the fresh air outlet of the indoor unit through the first flow path of the diverter valve, and is connected to the oxygen production module and the indoor oxygen port through the second flow path of the diverter valve, so that the air conditioner has both the oxygen production function and the fresh air function; according to the specific operation mode of the air conditioner, such as the oxygen production mode, the fresh air mode, and the fresh air + oxygen production mode (i.e., the dynamic oxygen production mode), the corresponding components in the air compressor, the diverter valve and the oxygen production machine are controlled to start, and the opening of the diverter valve in the corresponding mode is controlled according to the indoor oxygen concentration, so as to realize the coordinated oxygen production function and the fresh air function to accurately adjust the indoor air quality; thus, by enabling the air conditioner to have both the oxygen production function and the fresh air function, the indoor air conditioning quality can be accurately adjusted to improve the indoor comfort.

[0097] According to an embodiment of the present invention, a control device for an air conditioner corresponding to the control method for an air conditioner is also provided. Figure 5 The schematic diagram of the structure of an embodiment of the device of the present invention is shown. The air conditioner has an air compressor, a diverter valve, an oxygen production module, a fresh air outlet of the indoor unit and an oxygen outlet of the indoor unit; the diverter valve has a first flow path and a second flow path; the output end of the air compressor is connected to the fresh air outlet of the indoor unit through the first flow path to realize the fresh air function of the air conditioner, and is connected to the oxygen outlet of the indoor unit through the second flow path and the oxygen production module to realize the oxygen production function of the air conditioner; the scheme of the present invention provides a new type of air conditioner with fresh air and oxygen production functions, which not only has conventional cooling and heating functions, but also has a separate fresh air function, a separate oxygen production function and a dynamic oxygen production function. Therefore, in addition to the air conditioning components of a conventional air conditioner, the air conditioner also includes components related to the fresh air function and the oxygen production function. Figure 7 This is a structural diagram of a new type of fresh air oxygen-generating air conditioner indoor unit layout. Figure 7As shown, the indoor unit of the air conditioner is designed with a fresh air outlet and an oxygen outlet. In related schemes, the power source of the fresh air air conditioner is generally the indoor fan, and the power source of the oxygen-making air conditioner is the air compressor and is located outdoors; there are problems of multiple and scattered power sources, and the energy consumption is high when both are turned on at the same time. In the scheme of the present invention, the fresh air and oxygen-making functions share a set of power equipment, namely the air compressor, so that the two functional modules of oxygen-making and fresh air are combined, the power equipment is reduced, and the overall structural size is reduced. In the scheme of the present invention, by merging the power sources of the fresh air function and the oxygen-making function, the number of components is reduced, the utilization rate of components is improved, and the energy consumption of air conditioning is reduced.

[0098] In some embodiments, the air conditioner has an indoor unit air outlet; the indoor unit fresh air outlet and / or the indoor unit oxygen outlet are both located on the side wall of the indoor unit air outlet of the air conditioner. Figure 7 As shown, preferably, the fresh air outlet and oxygen outlet of the air conditioner indoor unit are located on the side of the air duct to facilitate mixing with the air conditioning airflow and improve the air supply comfort.

[0099] In some embodiments, a filtering device and / or a dehumidifying device is provided at the input end of the air compressor, so that outdoor air passes through the filtering device and / or the dehumidifying device before entering the air compressor, which is beneficial to improving the cleanliness of the air finally input into the room, and can also prevent impurities and moisture in the outdoor air from damaging the air compressor, thereby helping to protect the air compressor itself.

[0100] In some embodiments, a muffler is provided between the first flow path and the fresh air outlet of the indoor unit.

[0101] Figure 8 This is a schematic diagram of the structure of a new type of fresh air oxygen air conditioner outdoor unit layout. Figure 8 As shown, the outdoor unit of the present invention is composed of a conventional air conditioner outdoor unit + the distribution area of ​​the fresh air and oxygen production module of the present invention. In the scheme of the present invention, the fresh air and oxygen production related parts include power equipment, oxygen production molecular sieve, filter device, dehumidification device, buffer oxygen storage device, diverter valve, muffler, flow control valve, environmental temperature sensor, one-way valve, fresh air pipe, etc.

[0102] like Figure 8 As shown, the air conditioner outdoor unit is designed with a high layer on the top of the conventional outdoor unit. The high layer is used for oxygen-related parts of the molecular sieve oxygen production module, including power equipment, oxygen molecular sieve, filter device, dehumidification device, buffer oxygen storage device, diverter valve, muffler, flow control valve, environmental temperature sensor, one-way valve, etc. Preferably, the power equipment is an oil-free air compressor to ensure sufficient power and clean and fresh air compressed by it. Preferably, 2 or more molecular sieves are used for oxygen molecular screening to ensure oxygen supply and concentration.

[0103] In the related schemes, the fresh air function and the oxygen production function are controlled separately, lacking dynamic synergy. However, the scheme of the present invention uses oxygen concentration detection equipment to switch between oxygen production and fresh air modes, achieving dynamic oxygen production with coordinated control and adjusting the air freshness. In the scheme of the present invention, the fresh air function and the oxygen production function are controlled by a diverter valve, which reduces the exhaust gas discharge of the air compressor, improves its work efficiency, and realizes dynamic regulation of the fresh air volume and oxygen production volume.

[0104] In some embodiments, the oxygen production module includes: a molecular sieve oxygen production tower four-way valve, a first oxygen production tower, a second oxygen production tower, and a buffer oxygen storage device; the second flow path first passes through the molecular sieve oxygen production tower four-way valve, then passes through the first oxygen production tower and the second oxygen production tower respectively, and then passes through the buffer oxygen storage device to connect to the indoor unit oxygen outlet. Preferably, a first one-way valve such as one-way valve 1 is provided between the second flow path and the molecular sieve oxygen production tower four-way valve, and a second one-way valve such as one-way valve 2 is provided at the input end of the buffer oxygen storage device to ensure the one-way flow of air and avoid waste caused by backflow.

[0105] Fig. 9 The schematic diagram is a structural diagram of a new type of fresh air oxygen-generating air conditioning component association system. Fig. 9 In the example shown, compared with the structure of related solutions, the fresh air fan is reduced and the air compressor is used directly, so the fresh air volume is larger and the indoor ventilation efficiency is improved; the diverter valve dynamically adjusts the oxygen and fresh air flow to achieve rapid indoor air renewal and oxygen concentration adjustment. Fig. 9 As shown, an oxygen concentration detector is designed on the housing of the filter device for outdoor oxygen concentration detection and for the control of relevant dynamic oxygen production schemes of the air conditioner. The temperature sensing package is located on the air compressor, mainly monitoring the temperature at the outlet of the air compressor to prevent the system temperature from being too high. Preferably, the diverter valve is an electronically controlled diverter valve, which can adjust the left and right openings according to the preset logic of the detection data, and the diverter valve has a real-time flow monitoring function, which calculates the flow on the left and right sides respectively, and feeds back to the controller in real time. Preferably, a muffler is connected in series between the diverter valve and the fresh air outlet of the indoor unit to reduce wind noise and transmission sound.

[0106] exist Fig. 9 In the example shown, the filter device and the dehumidification device are connected to the pipeline where the air compressor is located in turn; the pipeline where the air compressor is located is divided into two routes after passing through the diverter valve: one route is connected to the fresh air outlet of the indoor unit after passing through the muffler, and the other route is connected to the first valve port of the molecular sieve oxygen tower four-way valve after passing through the one-way valve 1. The second valve port of the molecular sieve oxygen tower four-way valve is connected to the first end of the one-way valve 2 after passing through the oxygen tower 2, the third valve port of the molecular sieve oxygen tower four-way valve is connected to the nitrogen exhaust port, and the fourth valve port of the molecular sieve oxygen tower four-way valve is connected to the first end of the one-way valve 2 after passing through the oxygen tower 1. The second end of the one-way valve 2 is connected to the oxygen outlet of the indoor unit after passing through the buffer oxygen storage device.

[0107] In the related schemes, the oxygen production control process lacks consideration of the oxygen content of the outdoor environment, and the indoor oxygen content regulation scheme is relatively simple, and the comfort is poor. In the scheme of the present invention, dynamic oxygen production is dynamically regulated according to the numerical relationship between the set oxygen content, indoor oxygen content and outdoor oxygen content, which can effectively improve the regulation of indoor air oxygen content parameters and freshness. In the scheme of the present invention, through the dynamic regulation of the fresh air volume and oxygen production volume, a large flow of oxygen-enriched air and a small flow of high-oxygen air are obtained, which improves the comfort of indoor oxygen content parameter regulation.

[0108] In the scheme of the present invention, Figure 5 As shown, the air conditioner control device includes: an acquisition unit 102 and a control unit 104.

[0109] The control unit 104 is configured to determine the oxygen adjustment mode of the air conditioner after the air conditioner is started; the oxygen adjustment mode of the air conditioner includes: a single oxygen production mode, a single fresh air mode, and any one of an oxygen production and fresh air mixed mode. The specific functions and processing of the control unit 104 refer to step S110.

[0110] The control unit 104 is further configured to control the start of the air compressor, control the opening and closing and the opening degree of at least one of the first flow path and the second flow path according to the determined oxygen adjustment mode of the air conditioner, and control the start of the oxygen production module in the single oxygen production mode or the oxygen production and fresh air mixed mode, so that the air conditioner runs the oxygen adjustment mode of the air conditioner. The specific functions and processing of the control unit 104 are also shown in step S120.

[0111] In some embodiments, the control unit 104 controls the start-up of the air compressor, controls the opening and closing and the opening degree of at least one of the first flow path and the second flow path, and controls the start-up of the oxygen production module in the oxygen production mode alone or the oxygen production and fresh air mixed mode, including any of the following start-up control situations:

[0115] Fig.10 The figure is a flowchart of the start-up status of components and their control methods in different modes. Fig.10 As shown, the start-up status of the start-up components and their control methods in different modes include:

[0116] Step 1: After the air conditioner is started, the operation mode is determined, and then step 2, step 3, step 4, or step 5 is executed. Preferably, the operation mode is mainly selected by the user and does not involve active startup. Fig.10 As shown, the operating modes are divided into four categories, including conventional cooling or heating mode, oxygen production mode, fresh air mode, and fresh air + oxygen production mode. Preferably, the latter three modes can be entered by the user through autonomous selection under the condition that the conventional cooling or heating mode is started. The main function of the air conditioner is cooling and heating. Whether the user turns on the fresh air or oxygen production function can be selectively turned on by the remote control, application (Application, App), voice, etc., which is called the autonomous selection process.

[0117] Step 2: If only the cooling or heating mode is entered, the air conditioner starts normally, and other components do not start.

[0118] Step 3: If the oxygen production mode is started or entered, the right side of the diverter valve is opened to the maximum and the left side is closed; the air compressor is started; the oxygen molecular sieve oxygen production tower four-way valve is started; and the oxygen production mode is entered. In this way, when the user turns on the oxygen production mode, the maximum opening is used to produce oxygen, and the set oxygen concentration can be quickly reached.

[0119] Step 4: If the fresh air mode is started or entered, the left side of the diverter valve is opened to the maximum and the right side is closed; the air compressor is started; and the fresh air mode is entered. In this way, when the user turns on the fresh air mode, the fresh air is delivered at the maximum opening, which can quickly achieve indoor air renewal.

[0120] Step 5: If the fresh air + oxygen production mode is started or entered, the dynamic oxygen production mode is entered. In this way, in the fresh air + oxygen production mode, the indoor oxygen concentration is dynamically adjusted to achieve rapid adjustment of indoor air freshness.

[0121] In the scheme of the present invention, the oxygen production function and the fresh air function are jointly applied and coordinated controlled on the air conditioner, with a reversing valve, a fresh air function, no fresh air fan, and an emergency mode. The two functional modules of oxygen production and fresh air are combined to reduce power equipment and reduce the overall structure size. At the same time, the oxygen concentration detection equipment is used to switch the oxygen production and fresh air modes to achieve coordinated control of dynamic oxygen production and adjust the air freshness.

[0122] The acquisition unit 102 is configured to acquire the indoor oxygen content parameter of the air conditioner and acquire the outdoor oxygen content parameter of the air conditioner when the air conditioner is running in the oxygen adjustment mode of the air conditioner. The specific functions and processing of the acquisition unit 102 refer to step S130.

[0123] The control unit 104 is further configured to control the air compressor to continue to operate or stop in combination with the indoor oxygen content parameter of the air conditioner, the outdoor oxygen content parameter of the air conditioner, and the set oxygen content parameter, control the opening of the second flow path in the oxygen production and fresh air mixed mode, and control the oxygen production module to continue to operate or stop in the single oxygen production mode or the oxygen production and fresh air mixed mode, so as to adjust the oxygen content parameter and / or freshness of the indoor air of the air conditioner and improve indoor comfort. The specific functions and processing of the control unit 104 are also shown in step S140.

[0124] The control scheme of a fresh air oxygen-generating air conditioner provided by the solution of the present invention is a scheme that has both fresh air and oxygen-generating functions and can dynamically adjust the fresh air volume and oxygen production volume, thereby quickly adjusting the indoor air quality. In the solution of the present invention, an air conditioner with both fresh air and oxygen-generating functions is provided, and the fresh air and oxygen-generating functions share a set of power equipment, namely, an air compressor; three operating modes can be realized, namely, a separate fresh air ventilation mode, a separate oxygen production adjustment mode, and a dynamic oxygen production (i.e., fresh air + oxygen production) mode, which can quickly refresh and enrich the indoor air quality; dynamic oxygen production is dynamically regulated according to the numerical relationship between the set oxygen content, the indoor oxygen content, and the outdoor oxygen content, which can effectively improve the adjustment of indoor air oxygen content parameters and freshness, and improve indoor comfort.

[0125] In some embodiments, the control unit 104 controls the air compressor to continue to run or stop, controls the opening of the second flow path in the oxygen production and fresh air mixed mode, and controls the oxygen production module to continue to run or stop in the oxygen production mode alone or in the oxygen production and fresh air mixed mode, including: the process of adjusting the oxygen content parameter in the oxygen production mode alone is as follows:

[0126] The control unit 104 is further configured to determine whether the indoor oxygen content parameter of the air conditioner reaches the set oxygen content parameter if the oxygen adjustment mode of the air conditioner is determined to be the single oxygen production mode. The specific functions and processing of the control unit 104 are also shown in step S210.

[0127] The control unit 104 is further configured to maintain the first flow path closed, maintain the second flow path open and the opening degree is the set maximum opening degree if it is determined that the indoor oxygen content parameter of the air conditioner does not reach the set oxygen content parameter, and control the molecular sieve oxygen tower four-way valve to continue to operate when the oxygen production module includes a molecular sieve oxygen tower four-way valve, and control the air compressor to continue to operate. The specific functions and processing of the control unit 104 are also shown in step S220.

[0128] The control unit 104 is further configured to, if it is determined that the indoor oxygen content parameter of the air conditioner has reached the set oxygen content parameter, control the molecular sieve oxygen tower four-way valve to shut down when the oxygen production module includes a molecular sieve oxygen tower four-way valve, and control the air compressor to shut down and close the diverter valve. The specific functions and processing of the control unit 104 are also shown in step S230.

[0129] like Fig.10 As shown, the start-up status of components in different modes and their control methods also include: in step 3, if the oxygen production mode is started or entered, the right side of the diverter valve is opened to the maximum and the left side is closed; the air compressor is started; the four-way valve of the oxygen production molecular sieve oxygen production tower is started; and the oxygen production mode is entered. As oxygen is continuously produced, the indoor oxygen concentration increases, and the set oxygen concentration and the indoor detected oxygen concentration are compared synchronously: if the indoor oxygen concentration reaches the set oxygen concentration, the oxygen production molecular tower and the air compressor are shut down, and the diverter valve is closed (that is, no air passes) to avoid excessive oxygen concentration, resulting in oxygen intoxication or other safety accidents; if it is not reached, it continues to run. In this way, when the user turns on the oxygen production mode, the maximum opening oxygen production can quickly reach the set oxygen concentration, and dynamically adjust to accurately control the indoor oxygen content parameters and improve indoor comfort.

[0130] In some embodiments, the control unit 104 controls the air compressor to continue to run or stop, controls the opening of the second flow path in the oxygen production and fresh air mixed mode, and controls the oxygen production module to continue to run or stop in the oxygen production mode alone or in the oxygen production and fresh air mixed mode, in combination with the indoor oxygen content parameter of the air conditioner, the outdoor oxygen content parameter of the air conditioner, and the set oxygen content parameter, and also includes: the process of adjusting the oxygen content parameter in the fresh air mode alone, which is as follows:

[0131] The control unit 104 is further configured to determine whether the indoor oxygen content parameter of the air conditioner reaches the set oxygen content parameter if the oxygen adjustment mode of the air conditioner is determined to be the single fresh air mode. The specific functions and processing of the control unit 104 are also shown in step S310.

[0132] The control unit 104 is further configured to maintain the first flow path open and the opening degree is the set maximum opening degree, maintain the second flow path closed, and control the air compressor to continue to operate if it is determined that the indoor oxygen content parameter of the air conditioner does not reach the set oxygen content parameter. The specific functions and processing of the control unit 104 are also shown in step S320.

[0133] The control unit 104 is further configured to control the air compressor to stop and close the diverter valve if it is determined that the indoor oxygen content parameter of the air conditioner has reached the set oxygen content parameter. The specific functions and processing of the control unit 104 are also shown in step S330.

[0134] like Fig.10 As shown, the start-up status of components in different modes and their control methods also include: in step 4, if the fresh air mode is started or entered, the left side of the diverter valve is opened to the maximum and the right side is closed; the air compressor is started; and the fresh air mode is entered. With the continuous introduction of fresh air for ventilation, the indoor air quality is improved, and the set oxygen concentration and the oxygen concentration detected indoors are compared synchronously: if the indoor oxygen concentration reaches the set oxygen concentration, indicating that the overall indoor air renewal is completed, the air compressor is shut down and the diverter valve is closed (that is, no air passes); if it is not reached, it continues to run. Preferably, the set oxygen concentration = outdoor oxygen concentration. In this way, when the user turns on the fresh air mode, the maximum opening fresh air delivery can quickly realize indoor air renewal, and dynamically adjust to accurately control the indoor oxygen content parameters and improve indoor comfort.

[0135] In some embodiments, the control unit 104 controls the air compressor to continue to run or stop, controls the opening of the second flow path in the oxygen production and fresh air mixed mode, and controls the oxygen production module to continue to run or stop in the oxygen production mode alone or in the oxygen production and fresh air mixed mode, in combination with the indoor oxygen content parameter of the air conditioner, the outdoor oxygen content parameter of the air conditioner, and the set oxygen content parameter, further comprising:

[0136] The control unit 104 is further specifically configured to, if it is determined that the oxygen adjustment mode of the air conditioner is the separate fresh air mode, then after the air compressor is turned on or the air compressor continues to run: if it is determined that the indoor oxygen content parameter of the air conditioner is greater than the outdoor oxygen content parameter of the air conditioner, control the air compressor to continue running, until it is determined that the indoor oxygen content parameter of the air conditioner has reached the set oxygen content parameter, control the air compressor to stop and close the diverter valve.

[0137] And / or, the control unit 104 is further configured to, if it is determined that the oxygen adjustment mode of the air conditioner is the separate fresh air mode, then, when it is determined that the indoor oxygen content parameter of the air conditioner has reached the set oxygen content parameter, control the air compressor to stop and close the diverter valve for a set time period; wherein the set time period is the ratio of the space size parameter of the room where the air conditioner is located to the fresh air flow parameter in the separate fresh air mode.

[0138] like Fig.10 As shown, the start-up status of components in different modes and their control methods also include: in step 4, in addition, if the indoor oxygen concentration is detected to be higher than the outdoor oxygen concentration during the fresh air start-up stage, the fresh air is still running, and the fresh air stop condition is still that the indoor oxygen concentration reaches the set oxygen concentration; if the indoor oxygen concentration is detected to be = the set oxygen concentration during the fresh air start-up stage, the stop time of the fresh air operation is a certain time period t, and the time period t = room space size / fresh air flow rate; wherein the room space size is input by the user when installing the air conditioner, and the fresh air flow rate is the real-time flow rate provided by the diverter. In this way, the fresh air stop time is adjusted according to the indoor oxygen concentration to achieve safe indoor air regulation and avoid oxygen intoxication or excessive oxygen concentration. Under high oxygen concentration conditions, in order to avoid the discomfort caused by oxygen intoxication or other high oxygen concentration conditions, fresh air input is required for air conditioning.

[0139] In some embodiments, the control unit 104 controls the air compressor to continue to run or stop, controls the opening of the second flow path in the oxygen production and fresh air mixed mode, and controls the oxygen production module to continue to run or stop in the oxygen production mode alone or in the oxygen production and fresh air mixed mode, in combination with the indoor oxygen content parameter of the air conditioner, the outdoor oxygen content parameter of the air conditioner, and the set oxygen content parameter, and further includes: the process of adjusting the oxygen content parameter in the oxygen production and fresh air mixed mode, which is specifically as follows:

[0140] The control unit 104 is further configured to determine the relationship between the set oxygen content parameter, the outdoor oxygen content parameter of the air conditioner, and the indoor oxygen content parameter of the air conditioner if the oxygen adjustment mode of the air conditioner is determined to be the oxygen production and fresh air mixed mode. The specific functions and processing of the control unit 104 are also shown in step S410.

[0141] The control unit 104 is further configured to control the opening of the second flow path to be a first set opening if it is determined that the outdoor oxygen content parameter of the air conditioner is greater than the indoor oxygen content parameter of the air conditioner and less than the set oxygen content parameter, and then determine whether the indoor oxygen content parameter of the air conditioner is equal to the set oxygen content parameter. The specific functions and processing of the control unit 104 are also shown in step S420.

[0142] The control unit 104 is further configured to control the opening of the second flow path to a second set opening if it is determined that the indoor oxygen content parameter of the air conditioner is greater than the outdoor oxygen content parameter of the air conditioner and less than the set oxygen content parameter, and then determine whether the indoor oxygen content parameter of the air conditioner is equal to the set oxygen content parameter; the upper limit of the second set opening is less than the lower limit of the first set opening. The specific functions and processing of the control unit 104 are also shown in step S430.

[0143] The control unit 104 is further configured to control the opening of the second flow path to a third set opening if it is determined that the set oxygen content parameter is greater than the outdoor oxygen content parameter of the air conditioner and less than the indoor oxygen content parameter of the air conditioner, and then determine whether the indoor oxygen content parameter of the air conditioner is equal to the set oxygen content parameter; the upper limit of the third set opening is less than the lower limit of the second set opening. The specific functions and processing of the control unit 104 are also shown in step S440.

[0144] The control unit 104 is further configured to maintain the first flow path open and the opening degree is the set maximum opening degree, maintain the second flow path open and the opening degree is the set maximum opening degree, if it is determined that the indoor oxygen content parameter of the air conditioner is not equal to the set oxygen content parameter, and control the molecular sieve oxygen tower four-way valve to continue to operate when the oxygen production module includes a molecular sieve oxygen tower four-way valve, control the air compressor to continue to operate, and then return to re-determine the size relationship between the set oxygen content parameter, the outdoor oxygen content parameter of the air conditioner, and the indoor oxygen content parameter of the air conditioner. The specific functions and processing of the control unit 104 are also shown in step S450.

[0145] The control unit 104 is further configured to, if it is determined that the indoor oxygen content parameter of the air conditioner is equal to the set oxygen content parameter, control the molecular sieve oxygen tower four-way valve to shut down when the oxygen production module includes a molecular sieve oxygen tower four-way valve, and control the air compressor to shut down and close the diverter valve. The specific functions and processing of the control unit 104 are also shown in step S460.

[0146] like Fig.10 As shown, the start-up status of components in different modes and their control methods also include: in step 5, if the fresh air + oxygen production mode is started or entered, the dynamic oxygen production mode is entered. The operation of this mode is related to the oxygen concentration, including the set oxygen concentration, indoor oxygen concentration, and outdoor oxygen concentration. It should be noted that the oxygen concentration in the general living area of ​​humans is 20.9%. Under normal circumstances, the indoor oxygen concentration is lower than the outdoor oxygen concentration due to various consumptions (such as human breathing, equipment oxygen consumption, etc.) without additional oxygen addition. Therefore, for air conditioners with oxygen production function, the set value of oxygen concentration, that is, the set oxygen concentration, is generally not less than the outdoor oxygen concentration. Therefore, the following three situations occur:

[0147] The first case: set oxygen concentration> outdoor oxygen concentration> indoor oxygen concentration; then the right opening of the diverter valve is [80%; 100%].

[0148] The second situation: set oxygen concentration>indoor oxygen concentration>outdoor oxygen concentration; right side opening of the diverter valve [60%; 80%).

[0149] The third situation: indoor oxygen concentration > set oxygen concentration > outdoor oxygen concentration; right side opening of the diverter valve [0%; 20%).

[0150] As dynamic oxygen production proceeds, indoor air quality improves, and the set oxygen concentration is compared with the oxygen concentration detected indoors: if the indoor oxygen concentration reaches the set oxygen concentration, it means that the overall indoor quality has met the set requirements, and the air compressor stops; if it does not meet the requirements, it continues to run. In this way, in the fresh air + oxygen production mode, the indoor oxygen concentration is dynamically adjusted to achieve rapid adjustment of indoor air freshness, and dynamic adjustment is performed to accurately control indoor oxygen content parameters and improve indoor comfort.
