[0038] In order to make the purpose, technical scheme and advantages of the present application more clear, the following will combine the specific embodiments of the present application and the corresponding drawings to clearly and completely describe the technical scheme of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0039] It is considered that the oxygen making air conditioner has certain health care effect for special groups (such as the elderly, children, and people with poor heart and lung function, etc.), and compared with the conventional air conditioner and fresh air air conditioner, the oxygen making air conditioner can quickly realize high-precision oxygen concentration control. Figure 6 It is considered that the oxygen making air conditioner has certain health care effect for special groups (such as the elderly, children, and people with poor heart and lung function, etc.), and compared with the conventional air conditioner and fresh air air conditioner, the oxygen making air conditioner can quickly realize high-precision oxygen concentration control. Figure 6 As shown in FIG. 1, the indoor air oxygen content is different after the different air conditioners are operated for different time. The indoor air quality needs to be adjusted in the fresh air mode, for example, the indoor air pollution needs to be ventilated in the fresh air mode when the baby defecates in the room. However, the oxygen making air conditioner and the fresh air air conditioner are separately arranged, and the indoor air quality cannot be accurately adjusted to improve the indoor comfort.

[0040] Therefore, the present application provides a control method of air conditioner, specifically a control method of fresh air oxygen making air conditioner, which has a separate fresh air ventilation mode, a separate oxygen making adjustment mode and a dynamic oxygen making (i.e. fresh air + oxygen making) mode, and can quickly ventilate and enrich the indoor air quality. The dynamic oxygen making is dynamically controlled according to the numerical relationship of the set oxygen content, the indoor oxygen content and the outdoor oxygen content, which can effectively adjust the indoor air oxygen content parameter and freshness, and improve the indoor comfort.

[0041] According to the embodiments of the present application, a control method of air conditioner is provided, as shown in FIG. 2. Figure 1A flowchart of an embodiment of the method of the present application is shown. The air conditioner has an air compressor, a flow divider, an oxygen generating module, an indoor unit fresh air outlet and an indoor unit oxygen outlet; the flow divider has a first flow path and a second flow path; the output end of the air compressor is connected to the indoor unit fresh air outlet through the first flow path to realize the fresh air function of the air conditioner, and is connected to the indoor unit oxygen outlet through the second flow path and the oxygen generating module to realize the oxygen generating function of the air conditioner; the scheme of the present application provides a new type of air conditioner for testing fresh air and oxygen generating functions. The air conditioner not only has conventional refrigeration and heating functions, but also has separate fresh air function, separate oxygen generating function and dynamic oxygen generating function. Therefore, in addition to the air conditioner components possessed by conventional air conditioners, the air conditioner also includes fresh air function and oxygen generating function related components. Figure 7 A structural schematic diagram of a new type of fresh air oxygen generating air conditioner indoor unit layout is shown. As shown in Figure 7 The air conditioner indoor unit is designed with a fresh air outlet and an oxygen outlet. In related schemes, the power source of the fresh air conditioner is generally an indoor fan, and the power source of the oxygen generating air conditioner is an air compressor located outdoors; there are problems of multiple power sources and dispersion, and large energy consumption during simultaneous opening. The scheme of the present application shares a set of power equipment, i.e. an air compressor, for the fresh air and oxygen generating functions. In this way, the oxygen generating and fresh air two function modules are combined, the power equipment is reduced, and the overall structure size is reduced. In the scheme of the present application, by merging the fresh air function and oxygen generating function power sources, the number of components is reduced, the utilization rate of components is improved, and the energy consumption of the air conditioner 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 located on the side wall of the indoor unit air outlet of the air conditioner; as shown in Figure 7 Preferably, the fresh air outlet and the oxygen outlet of the air conditioner indoor unit are located on the side of the air duct, which facilitates mixing with the air flow of the air conditioner and improves the comfort of the air supply. In the scheme of the present application, the specific setting position 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 is separately circulated and 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 outlet section of the bottom shell of the indoor unit of the air conditioner, which facilitates pipe running and can also take advantage of the large air volume circulation of the indoor fan of the air conditioner to quickly adjust the indoor oxygen concentration.

[0043] In some embodiments, a filtering device and / or a dehumidifying device are arranged at the input end of the air compressor, so that the outdoor air enters the air compressor after passing through the filtering device and / or the dehumidifying device. This is beneficial to improve the cleanliness of the air finally input into the room, and can also avoid damage to the air compressor caused by impurities and moisture in the outdoor air, thereby being beneficial to protecting 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 structural diagram of a new type of fresh air oxygen-generating 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 and the distribution area of ​​the fresh air and oxygen production module of the present invention. In the solution of the present invention, the components related to fresh air and oxygen production include power equipment, oxygen production molecular sieve, filter device, dehumidification device, buffer oxygen storage device, diverter valve, muffler, flow control valve, ambient temperature sensor, check valve, fresh air duct, etc.

[0046] like Figure 8 As shown, the air conditioner outdoor unit is designed with a raised floor above a conventional outdoor unit. This raised floor houses the oxygen-generating components of the molecular sieve oxygen production module, including the power unit, oxygen molecular sieve, filter, dehumidifier, buffer oxygen reservoir, diverter valve, muffler, flow control valve, ambient temperature sensor, and check valve. Preferably, the power unit is an oil-free air compressor to ensure sufficient power and clean, fresh air after compression. Preferably, two or more molecular sieve towers are used for the oxygen production to ensure a stable oxygen supply and concentration.

[0047] In related solutions, the fresh air and oxygen production functions are controlled separately, lacking dynamic synergy. However, the solution of the present invention utilizes oxygen concentration detection equipment to switch between oxygen production and fresh air modes, achieving coordinated dynamic oxygen production and regulating air freshness. In this solution, the fresh air and oxygen production functions are controlled by a diverter valve, reducing exhaust emissions from the air compressor and improving its efficiency, while also enabling dynamic regulation of fresh air and oxygen production volumes.

[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 reservoir; 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, and then passes through the buffer oxygen reservoir to connect to the oxygen outlet of the indoor unit. 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 reservoir to ensure one-way flow of air and avoid waste caused by backflow.

[0049] Figure 9 This is a structural diagram of a new type of fresh air oxygen-generating air conditioning component association system. Figure 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, which increases the fresh air volume and improves the indoor ventilation efficiency; the diverter valve dynamically adjusts the oxygen and fresh air flow to achieve rapid indoor air renewal and oxygen concentration adjustment.Figure 9 As shown, an oxygen concentration detector is designed on the filter device housing for outdoor oxygen concentration detection, for the air conditioner to control the relevant dynamic oxygen production scheme. The temperature sensing bag is located on the air compressor, mainly monitoring the temperature at the outlet of the air compressor to avoid high system temperature. Preferably, the shunt valve is an electronic type, which can adjust the left and right opening degrees according to the preset logic of the detection data, and the shunt valve has a flow real-time monitoring function, which calculates the flow on the left and right sides respectively and feeds back to the controller in real time. Preferably, an silencer is connected in series between the shunt valve and the indoor unit fresh air outlet to reduce wind noise and transmission noise.

[0050] In Figure 9 In the example shown, the filter device and the dehumidifying device are connected in sequence to the pipeline at the inlet of the air compressor; the pipeline at the outlet of the air compressor is divided into two paths after the shunt valve: one path is connected to the indoor unit fresh air outlet after the silencer, and the other path is connected to the first valve port of the molecular sieve oxygen production tower four-way valve after the one-way valve 1. The second valve port of the molecular sieve oxygen production tower four-way valve is connected to the first end of the one-way valve 2 after the oxygen production tower 2, the third valve port of the molecular sieve oxygen production tower four-way valve is connected to the nitrogen outlet, and the fourth valve port of the molecular sieve oxygen production tower four-way valve is connected to the first end of the one-way valve 2 after the oxygen production tower 1. The second end of the one-way valve 2 is connected to the indoor unit oxygen outlet after the buffer oxygen storage device.

[0051] In the related scheme, the oxygen production control process lacks consideration of the outdoor environment oxygen content, and the indoor oxygen content regulation scheme is relatively single, with poor comfort. However, the scheme of the present application dynamically regulates according to the numerical relationship of the set oxygen content, the indoor oxygen content and the outdoor oxygen content, which can effectively regulate the indoor air oxygen content parameter and the freshness. In the scheme of the present application, through dynamic regulation of the fresh air volume and the oxygen production volume, large-flow oxygen-enriched air and small-flow high-oxygen air are obtained, improving the comfort of indoor oxygen content parameter regulation.

[0052] In the scheme of the present application, as Figure 1 The control method of the air conditioner comprises steps S110 to S140.

[0053] At step S110, after the air conditioner is started, the oxygen regulation mode of the air conditioner is determined; the oxygen regulation mode of the air conditioner includes any one of the following modes: a separate oxygen production mode, a separate fresh air mode, and a mixed mode of oxygen production and fresh air.

[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 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 separate oxygen production mode or the mixed mode of oxygen production and fresh air, so that the air conditioner runs in the oxygen regulation mode of the air conditioner.

[0055] In some embodiments, in step S120, based on the determined oxygen adjustment 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 oxygen production mode alone or the oxygen production and fresh air mixed mode, including any of the following startup control situations:

[0056] The first startup control scenario: if it is determined that the oxygen adjustment mode of the air conditioner is the independent oxygen production mode, the first flow path is controlled to be closed, the second flow path is controlled to be opened and the opening is set to the maximum opening, the air compressor is controlled to start, and 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 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 is the set maximum opening, 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 is the set maximum opening, the second flow path is controlled to be opened and the opening is the set maximum opening, the air compressor is controlled to start, and 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 start.

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

[0060] Step 1: After the air conditioner is started, enter the operation mode determination, and then execute step 2 or step 3 or step 4 or step 5. Preferably, the operation mode is mainly selected by the user and does not involve active startup. Figure 10 As shown in the figure, 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 self-selection when the conventional cooling or heating mode is started. The main functions of the air conditioner are 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 self-selection process.

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

[0062] Step 3, if the oxygen generation mode is started or entered, the split valve is opened to the maximum on the right side and closed on the left side; the air compressor is started; the oxygen generation molecular sieve oxygen generation tower four-way valve is started; the oxygen generation mode is entered. In this way, in the case that the user starts the oxygen generation mode, the maximum oxygen generation is achieved, and the set oxygen concentration can be quickly reached.

[0063] Step 4, if the fresh air mode is started or entered, the split valve is opened to the maximum on the left side and closed on the right side; the air compressor is started; the fresh air mode is entered. In this way, in the case that the user starts the fresh air mode, the maximum fresh air delivery is achieved, and the indoor air can be quickly refreshed.

[0064] Step 5, if the fresh air + oxygen generation mode is started or entered, the dynamic oxygen generation mode is entered. In this way, in the fresh air + oxygen generation mode, the indoor oxygen concentration is dynamically adjusted, and the indoor air freshness is quickly adjusted.

[0065] In the scheme of the present application, the oxygen generation function and the fresh air function are combined and cooperatively controlled on the air conditioner, there is a reversing valve, a fresh air function, no fresh air fan, and an emergency mode. The oxygen generation and fresh air function modules are combined, the power equipment is reduced, the overall structure size is reduced, and the oxygen concentration detection equipment is used to switch the oxygen generation and fresh air modes, so that the dynamic oxygen generation is cooperatively controlled, and the air freshness is adjusted.

[0066] At step S130, if the air conditioner is running in the oxygen regulation mode of the air conditioner, the indoor oxygen content parameter of the air conditioner is obtained, and the outdoor oxygen content parameter of the air conditioner is obtained.

[0067] At step S140, 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 air compressor is controlled to continue running or stop, the opening degree of the second flow path is controlled in the oxygen generation and fresh air mixing mode, and the oxygen generation module is controlled to continue running or stop in the single oxygen generation mode or the oxygen generation and fresh air mixing mode, so as to realize the adjustment of the oxygen content parameter and / or the freshness of the indoor air of the air conditioner, and improve the indoor comfort.

[0068] The scheme of the application provides a fresh air oxygen making air conditioner control scheme, which has fresh air and oxygen making functions and can dynamically control the fresh air volume and oxygen making volume, thereby quickly adjusting indoor air quality. In the scheme of the application, an air conditioner having fresh air and oxygen making functions is provided, and the fresh air and oxygen making functions share a set of power equipment, i.e. an air compressor; three operation modes, i.e. a separate fresh air ventilation mode, a separate oxygen making adjustment mode and a dynamic oxygen making (i.e. fresh air + oxygen making) mode, can be realized to quickly refresh and oxygenate adjust indoor air quality; the dynamic oxygen making is dynamically controlled according to the numerical relationship of the set oxygen content, the indoor oxygen content and the outdoor oxygen content, which can effectively adjust the indoor air oxygen content parameter and freshness and improve indoor comfort.

[0069] In some embodiments, the step S140 of combining 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 degree of the second flow path in the oxygen making and fresh air mixing mode, and control the oxygen making module to continue running or stop in the separate oxygen making mode or the oxygen making and fresh air mixing mode includes a process of adjusting the oxygen content parameter in the separate oxygen making mode.

[0070] The following will be described in combination with Figure 2 The following will be described in combination with

[0071] In step S210, if it is determined that the oxygen adjustment mode of the air conditioner is the separate oxygen making mode, it is determined whether the indoor oxygen content parameter of the air conditioner reaches the set oxygen content parameter.

[0072] In 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 degree is the set maximum opening degree, the molecular sieve oxygen making tower four-way valve is controlled to continue running in the case that the oxygen making module includes the molecular sieve oxygen making tower four-way valve, and the air compressor is controlled to continue running.

[0073] In step S230, if it is determined that the indoor oxygen content parameter of the air conditioner reaches the set oxygen content parameter, the molecular sieve oxygen making tower four-way valve is controlled to stop in the case that the oxygen making module includes the molecular sieve oxygen making tower four-way valve, and the air compressor is controlled to stop and the shunt valve is closed.

[0074] As Figure 10As shown, the starting part opening state in different modes and the control method thereof further comprises: in step 3, if starting or entering the oxygen production mode, the opening degree of the right side of the flow divider valve is maximum, and the left side is closed; the air compressor is started; the oxygen production molecular sieve type oxygen production tower four-way valve is started; and the oxygen production mode is entered. With continuous oxygen production, 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 both stopped, and the flow divider valve is closed (that is, no air passes through), so as to avoid that the oxygen concentration is too high, resulting in drunken oxygen or other safety accidents; if not, continue to run. In this way, in the case that the user starts the oxygen production mode, the maximum opening degree is used for oxygen production, the set oxygen concentration can be quickly reached, and dynamic adjustment is carried out, so as to accurately control the indoor oxygen content parameter and improve the indoor comfort.

[0075] In some embodiments, in step S140, the indoor oxygen content parameter of the air conditioner, the outdoor oxygen content parameter of the air conditioner, and the set oxygen content parameter are combined to control the air compressor to continue running or stop, control the opening degree of the second flow path in the oxygen production and fresh air mixing 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 mixing mode, and the process of adjusting the oxygen content parameter in the single fresh air mode in the method of the air conditioner is further included.

[0076] The process of adjusting the oxygen content parameter in the single fresh air mode in the method of the air conditioner will be described below in combination with Figure 3 An embodiment flowchart of the process of adjusting the oxygen content parameter in the single fresh air mode in the method of the air conditioner is shown, which further illustrates the specific process of the process of adjusting the oxygen content parameter in the single fresh air mode in step S140, comprising steps S310 to S330.

[0077] In step S310, if it is determined that the oxygen regulation mode of the air conditioner obtained is the single fresh air mode, it is determined whether the indoor oxygen content parameter of the air conditioner reaches the set oxygen content parameter.

[0078] In 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 to be opened and the opening degree is maintained to be the set maximum opening degree, the second flow path is maintained to be closed, and the air compressor is controlled to continue running.

[0079] In step S330, if it is determined that the indoor oxygen content parameter of the air conditioner reaches the set oxygen content parameter, the air compressor is controlled to stop and the flow divider valve is closed.

[0080] As Figure 10As shown, the starting part opening state in different modes and the control method thereof further comprises: in step 4, if starting or entering the fresh air mode, the left side of the shunt 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 input of fresh air ventilation, the indoor air quality is improved, and the set oxygen concentration and the indoor detected oxygen concentration are compared: if the indoor oxygen concentration reaches the set oxygen concentration, it means that the indoor overall air replacement is completed, and the air compressor is stopped and the shunt valve is closed (i.e. no air passes through); if not, continue to run. Preferably, the set oxygen concentration = outdoor oxygen concentration. In this way, in the case that the user starts the fresh air mode, the maximum opening degree of fresh air delivery can quickly realize indoor air replacement and dynamic adjustment to accurately control the indoor oxygen content parameter and improve indoor comfort.

[0081] In some embodiments, the 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 degree of the second flow path in the oxygen generation and fresh air mixing mode, and control the oxygen generation module to continue running or stop in the single oxygen generation mode or the oxygen generation and fresh air mixing mode. It further comprises: if it is determined that the obtained oxygen regulation mode of the air conditioner is the single fresh air mode, then in the case that the air compressor is started 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 to run 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 shunt valve; and / or, if it is determined that the obtained oxygen regulation mode of the air conditioner is the single fresh air mode, then in the case that 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 shunt 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 single fresh air mode.

[0082] As Figure 10As shown, the starting part opening state in different modes and the control method thereof further comprises the following: in step 4, in addition, if the fresh air opening stage, it is detected that the indoor oxygen concentration is higher than the outdoor oxygen concentration, the fresh air is still running, and the fresh air stop condition is that the indoor oxygen concentration reaches the set oxygen concentration; that is, when the user uses the oxygen production function to increase the oxygen concentration, and then needs to adjust the oxygen concentration back to the normal concentration after a period of use, the function is needed to avoid the case that there is no stop reference value when the fresh air is running. If the fresh air opening stage, it is detected that the indoor oxygen concentration = the set oxygen concentration, then the stop time of the fresh air running is a certain time period t, the time period t = room space size / fresh air flow; wherein the room space size is input by the user when installing the air conditioner, and the fresh air flow is the real-time flow provided by the flow divider. In this way, the fresh air stop time is adjusted according to the indoor oxygen concentration, the indoor air safety adjustment is realized, and the drunk oxygen or high oxygen concentration condition is avoided. Under the condition of high concentration oxygen, in order to avoid the discomfort caused by drunk oxygen or other high concentration oxygen conditions, fresh air input is needed for air adjustment.

[0083] In some embodiments, in step S140, the indoor oxygen content parameter of the air conditioner, the outdoor oxygen content parameter of the air conditioner, and the set oxygen content parameter are combined to control the air compressor to continue running or stop, control the opening degree of the second flow path in the oxygen production and fresh air mixing 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 mixing mode, and the process of adjusting the oxygen content parameter in the oxygen production and fresh air mixing mode is further included.

[0084] The process of adjusting the oxygen content parameter in the oxygen production and fresh air mixing mode in the method of the present application will be described below Figure 4 An embodiment flowchart of the process of adjusting the oxygen content parameter in the oxygen production and fresh air mixing mode in the method of the present application is shown in the following figure, which further illustrates the specific process of adjusting the oxygen content parameter in the oxygen production and fresh air mixing mode in step S140, including steps S410 to S460.

[0085] In step S410, if it is determined that the obtained oxygen adjustment mode of the air conditioner is the oxygen production and fresh air mixing mode, the size relationship of 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] In 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 degree of the second flow path is controlled to be a first set opening degree, 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 at the set maximum opening, the second flow path is maintained open and the opening is at the set maximum opening, and 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, and then the process returns 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 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 be shut down, and the air compressor is controlled to be shut down and the diverter valve is closed.

[0091] like Figure 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 human living area 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 its oxygen concentration, that is, the set oxygen concentration, is generally not less than the outdoor oxygen concentration. Therefore, the following three situations arise:

[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 case: set oxygen concentration > indoor oxygen concentration > outdoor oxygen concentration; the split valve right side opening degree [60%; 80%).

[0094] The third case: indoor oxygen concentration > set oxygen concentration > outdoor oxygen concentration; the split valve right side opening degree [0%; 20%).

[0095] With the dynamic oxygen production, the indoor air quality is improved, and the set oxygen concentration and the indoor detected oxygen concentration are compared: if the indoor oxygen concentration reaches the set oxygen concentration, it means that the overall quality of the indoor reaches the set requirement, and the air compressor stops; if it does not reach, it continues to run. In this way, in the fresh air + oxygen production mode, the indoor oxygen concentration is dynamically adjusted, the indoor air freshness is quickly adjusted, and dynamic adjustment is performed to accurately control the indoor oxygen content parameter and improve the indoor comfort.

[0096] The technical scheme of the embodiment is adopted, a set of air compressors is arranged for the oxygen production function and the fresh air function of the air conditioner, the air compressor is connected to the fresh air outlet of the indoor unit after the first flow path of the split valve, and is connected to the oxygen production module and the indoor oxygen port after the second flow path of the split valve, so that the air conditioner has the oxygen production function and the fresh air function; according to the specific mode required for the air conditioner to run, such as the oxygen production mode, the fresh air mode, and the fresh air + oxygen production mode (i.e. dynamic oxygen production mode), the corresponding components in the air compressor, the split valve and the oxygen generator are controlled to start, and the opening degree of the split valve in the corresponding mode is controlled according to the indoor oxygen concentration, so as to realize accurate adjustment of the indoor air quality by the cooperative oxygen production function and fresh air function; thereby, by making the air conditioner have the oxygen production function and the fresh air function, the indoor air quality can be accurately adjusted to improve the indoor comfort.

[0097] According to the embodiment of the application, a control device of an air conditioner corresponding to the control method of the air conditioner is also provided. Referring to Figure 5 The structure schematic diagram of an embodiment of the device of the application is shown. The air conditioner has an air compressor, a split valve, an oxygen production module, a fresh air outlet of an indoor unit, and an oxygen outlet of the indoor unit; the split 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 after 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 after the second flow path and the oxygen production module to realize the oxygen production function of the air conditioner; the scheme of the application provides a novel air conditioner with fresh air and oxygen production functions. The air conditioner not only has conventional refrigeration and heating functions, but also has separate fresh air function, separate oxygen production function and dynamic oxygen production function. Therefore, in addition to the air conditioner parts possessed by conventional air conditioners, the air conditioner also includes fresh air function and oxygen production function related parts. Figure 7 It is a structure schematic diagram of a novel fresh air and oxygen production air conditioner indoor unit layout. As Figure 7As shown, the air conditioner indoor unit is designed with a fresh air outlet and an oxygen outlet. In related schemes, the power source of the fresh air conditioner is generally an indoor fan, and the power source of the oxygen generating air conditioner is an air compressor located outdoors; there are problems of multiple and dispersed power sources, and large energy consumption during simultaneous opening. The scheme of the present application shares a set of power equipment, i.e. an air compressor, for the fresh air and oxygen generating functions, so that the oxygen generating and fresh air functions are combined, the power equipment is reduced, and the overall structure size is reduced. In the scheme of the present application, by combining the power sources of the fresh air function and the oxygen generating function, the number of parts is reduced, the utilization rate of parts is improved, and the energy consumption of the air conditioner 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 located on the side wall of the indoor unit air outlet of the air conditioner. As shown in Figure 7 As shown, preferably, the air conditioner indoor unit fresh air outlet and oxygen outlet are located on the side of the air duct, which facilitates mixing with the air flow of the air conditioner and improves the comfort of the air supply.

[0099] In some embodiments, a filtering device and / or a dehumidifying device are arranged at the input end of the air compressor, so that the outdoor air enters the air compressor after passing through the filtering device and / or the dehumidifying device, which is beneficial to improve the cleanliness of the air finally input into the room and can also avoid damage to the air compressor caused by impurities and moisture in the outdoor air, thereby protecting the air compressor itself.

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

[0101] Figure 8 It is a structural schematic diagram of a new outdoor unit layout of a fresh air and oxygen generating air conditioner. As shown in Figure 8 As shown, it is composed of a conventional air conditioner outdoor unit and the fresh air and oxygen generating module distribution area of the present application. In the scheme of the present application, the fresh air and oxygen generating related parts, including power equipment, oxygen generating molecular sieve, filtering device, dehumidifying device, buffer oxygen storage device, flow dividing valve, silencer, flow control valve, environmental temperature sensing bag, one-way valve, fresh air pipe, etc.

[0102] As shown in Figure 8 The air conditioner outdoor unit is designed with an additional layer on the upper part of the conventional outdoor unit, which is used for the oxygen generating related parts of the molecular sieve type oxygen generating module, including power equipment, oxygen generating molecular sieve, filtering device, dehumidifying device, buffer oxygen storage device, flow dividing valve, silencer, flow control valve, environmental temperature sensing bag, one-way valve, etc. Preferably, the power equipment is an oil-free air compressor, which ensures sufficient power and clean and fresh air after compression. Preferably, 2 or more molecular sieves are selected for the oxygen generating molecular sieve, which ensures oxygen supply and concentration.

[0103] In the related scheme, the fresh air function and the oxygen production function are controlled separately, and the dynamic cooperation is lacking. In the scheme of the present application, the oxygen concentration detection device is used to switch the oxygen production and fresh air modes, so that the dynamic oxygen production is cooperatively controlled, and the air freshness is adjusted. In the scheme of the present application, the fresh air function and the oxygen production function are controlled by the shunt valve, the exhaust of the air compressor is reduced, the work efficiency is improved, and the dynamic regulation of the fresh air volume and the oxygen production volume is realized.

[0104] In some embodiments, the oxygen production module comprises 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 is connected to the indoor unit oxygen outlet after passing through the molecular sieve oxygen production tower four-way valve, the first oxygen production tower, the second oxygen production tower, and the buffer oxygen storage device in sequence. Preferably, a first one-way valve such as one-way valve 1 is arranged 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 arranged at the input end of the buffer oxygen storage device, so as to ensure the one-way flow of air and avoid waste caused by backflow.

[0105] Figure 9 It is a structural schematic diagram of a novel fresh air and oxygen production air conditioning component correlation system. Figure 9 Compared with the structure of the related scheme, the example shown reduces the fresh air fan, directly uses the air compressor, the fresh air volume is larger, and the indoor air exchange efficiency is improved; the shunt valve dynamically regulates the oxygen and fresh air flow, and realizes the rapid indoor air exchange and oxygen concentration regulation. Figure 9 As shown, an oxygen concentration detector is designed on the filter device housing for outdoor oxygen concentration detection, and is used for the control of the related dynamic oxygen production scheme of the air conditioner. The temperature sensing bag is located on the air compressor, and mainly monitors the temperature at the outlet of the air compressor to avoid high system temperature. Preferably, the shunt valve is an electronic type, which can adjust the opening degree of the left and right sides according to the preset logic of the detection data, and the shunt valve has a flow real-time monitoring function, which calculates the flow of the left and right sides respectively and feeds back to the controller in real time. Preferably, a silencer is connected in series between the shunt valve and the indoor unit fresh air outlet to reduce wind noise and transmission sound.

[0106] In Figure 9 In the example shown, the filter device and the dehumidification device are connected to the pipeline where the inlet of the air compressor is located in sequence; the pipeline where the outlet of the air compressor is located is divided into two paths after passing through the shunt valve: one path is connected to the indoor unit fresh air outlet after passing through the silencer, and the other path is connected to the first valve port of the molecular sieve oxygen production tower four-way valve after passing through one-way valve 1. The second valve port of the molecular sieve oxygen production tower four-way valve is connected to the first end of one-way valve 2 after passing through oxygen production tower 2, the third valve port of the molecular sieve oxygen production tower four-way valve is connected to the nitrogen outlet, and the fourth valve port of the molecular sieve oxygen production tower four-way valve is connected to the first end of one-way valve 2 after passing through oxygen production tower 1. The second end of one-way valve 2 is connected to the indoor unit oxygen outlet after passing through the buffer oxygen storage device.

[0107] In the related scheme, the oxygen production control process lacks consideration of the oxygen content of the outdoor environment, and the indoor oxygen content regulation scheme is relatively single and the comfort is poor. The scheme of the present application dynamically regulates the oxygen content according to the numerical relationship of the set oxygen content, the indoor oxygen content and the outdoor oxygen content, which can effectively regulate the indoor air oxygen content parameter and the freshness. In the scheme of the present application, through dynamic regulation of the fresh air volume and the oxygen production volume, high-flow oxygen-rich air and low-flow high-oxygen air are obtained, and the comfort of indoor oxygen content parameter regulation is improved.

[0108] In the scheme of the present application, as shown in Figure 5 The control device of the air conditioner comprises an acquisition unit 102 and a control unit 104.

[0109] The control unit 104 is configured to determine an oxygen regulation mode of the air conditioner after the air conditioner is started. The oxygen regulation mode of the air conditioner includes any one of a separate oxygen production mode, a separate fresh air mode, and a mixed mode of oxygen production and fresh air. For specific functions and processing of the control unit 104, see step S110.

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

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

[0112] The first start control situation: the control unit 104 is specifically further configured to, if the determined oxygen regulation mode of the air conditioner is the separate oxygen production mode, control the first flow path to be closed, control the second flow path to be opened and the opening degree to be a set maximum opening degree, control the air compressor to be started, and control the molecular sieve oxygen production tower four-way valve to be started in the case that the oxygen production module comprises the molecular sieve oxygen production tower four-way valve.

[0113] The second starting control case: the control unit 104 is specifically further configured to control the first flow path to be opened with a set maximum opening degree, control the second flow path to be closed, and control the air compressor to start if the determined oxygen regulation mode of the air conditioner is the single fresh air mode.

[0114] The third starting control case: the control unit 104 is specifically further configured to control the first flow path to be opened with a set maximum opening degree, control the second flow path to be opened with a set maximum opening degree, control the air compressor to start, and control the molecular sieve oxygen generator four-way valve to start if the determined oxygen regulation mode of the air conditioner is the oxygen generation and fresh air mixed mode.

[0115] Figure 10 The flowchart of the starting part opening state and its control method in different modes is shown in FIG. 1. Figure 10 As shown in FIG. 1, the starting part opening state and its control method in different modes include the following steps.

[0116] Step 1: After the air conditioner starts, the running mode is determined, and then step 2 or step 3 or step 4 or step 5 is executed. Preferably, the running mode is mainly selected by the user and does not involve active starting. As shown in FIG. 2, the running mode is divided into four categories, including the conventional refrigeration or heating mode, the oxygen generation mode, the fresh air mode, and the fresh air + oxygen generation mode. Preferably, the last three modes can be entered by the user through self-selection under the starting conditions of the conventional refrigeration or heating mode. The main function of the air conditioner is refrigeration and heating, and whether the user opens the fresh air or oxygen generation function can be selected by the user through the remote controller, the application (App), the voice, etc., which is called the self-selection process. Figure 10

[0117] Step 2: If only the refrigeration or heating mode is entered, the air conditioner is normally started, and other parts are not started.

[0118] Step 3: If the oxygen generation mode is started or entered, the right side of the flow valve is opened to the maximum, and the left side is closed; the air compressor is started; the oxygen generation molecular sieve oxygen generator four-way valve is started; and the oxygen generation mode is entered. In this way, in the case that the user opens the oxygen generation mode, the maximum opening degree oxygen generation can quickly reach the set oxygen concentration.

[0119] Step 4: If the fresh air mode is started or entered, the left side of the flow 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, in the case that the user opens the fresh air mode, the maximum opening degree fresh air delivery can quickly achieve indoor air renewal.

[0120] ​Step 5, if starting or entering fresh air + oxygen production mode, enter dynamic oxygen production mode. In this way, in the fresh air + oxygen production mode, the indoor oxygen concentration is dynamically adjusted to realize rapid adjustment of indoor air freshness.

[0121] In the scheme of the application, the oxygen production function and the fresh air function are jointly applied and cooperatively controlled on the air conditioner, there is a reversing valve, a fresh air function, no fresh air fan, and an emergency mode. The oxygen production and fresh air function modules are combined to reduce the power equipment and the overall structure size, and the oxygen concentration detection equipment is used to switch the oxygen production and fresh air mode to achieve dynamic oxygen production and cooperatively control 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 in the case that the air conditioner is running in the oxygen regulation mode of the air conditioner. The specific functions and processes of the acquisition unit 102 are described with reference to step S130.

[0123] The control unit 104 is further configured to control the air compressor to continue running or stop, control the opening degree of the second flow path in the oxygen production and fresh air mixing 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 mixing 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, to realize the adjustment of the oxygen content parameter and / or the freshness of the indoor air of the air conditioner and improve the indoor comfort. The specific functions and processes of the control unit 104 are also described with reference to step S140.

[0124] The control scheme of the fresh air and oxygen production air conditioner provided in the scheme of the application is a scheme that has both fresh air and oxygen production functions and can dynamically regulate the fresh air volume and the oxygen production volume to rapidly adjust the indoor air quality. In the scheme of the application, an air conditioner having both fresh air and oxygen production functions is provided, and the fresh air and oxygen production functions share a set of power equipment, i.e., an air compressor. Three operating modes, i.e., a single fresh air ventilation mode, a single oxygen production regulation mode, and a dynamic oxygen production (i.e., fresh air + oxygen production) mode, can be realized to rapidly refresh and oxygenate the indoor air quality. The dynamic oxygen production is dynamically regulated according to the numerical relationship among the set oxygen content, the indoor oxygen content, and the outdoor oxygen content, which can effectively adjust the indoor air oxygen content parameter and the freshness to improve the indoor comfort.

[0125] In some embodiments, the control unit 104 controls the air compressor to continue running 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 running 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, 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 a set oxygen content parameter if the oxygen adjustment mode of the air conditioner is determined to be the oxygen-only mode. The specific functions and processing of the control unit 104 are further described in step S210.

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

[0128] The control unit 104 is further configured to, if it determines that the indoor oxygen content parameter of the air conditioner has reached a set oxygen content parameter, control the molecular sieve oxygen tower four-way valve, if the oxygen production module includes a molecular sieve oxygen tower four-way valve, to shut down the 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 further described in step S230.

[0129] like Figure 10 As shown, the opening status of the starting components in different modes and the control method thereof 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 through) 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 perform dynamic adjustments 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 running 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 running 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. The process also includes: adjusting the oxygen content parameter in the fresh air mode alone, specifically as follows:

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

[0132] The control unit 104 is further configured to, if it determines that the indoor oxygen content parameter of the air conditioner has not reached the set oxygen content parameter, maintain the first flow path open at a set maximum opening, maintain the second flow path closed, and control the air compressor to continue operating. The specific functions and processing of the control unit 104 are further described 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 determines 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 Figure 10 As shown, the opening status of the starting components in different modes and the control method thereof 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. As fresh air is continuously introduced for ventilation, the indoor air quality is improved, and the set oxygen concentration and the oxygen concentration detected indoors are compared simultaneously: 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 (ie, no air passes through); 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 perform dynamic adjustment 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 running 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 running or stop in the oxygen production alone mode or the oxygen production and fresh air mixed mode, based on 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 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 Figure 10 As shown, the activation 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 activation phase, the fresh air will continue to operate, and the fresh air stop condition is still when the indoor oxygen concentration reaches the set oxygen concentration; if the indoor oxygen concentration is detected to be equal to the set oxygen concentration during the fresh air activation phase, the fresh air operation will be stopped for a certain period of time t, where t = room space size / fresh air flow rate; 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 conditioning and avoid oxygen intoxication or excessive oxygen concentration. Under high oxygen concentration conditions, fresh air input is required for air conditioning to avoid oxygen intoxication or other discomfort caused by high oxygen concentration conditions.

[0139] In some embodiments, the control unit 104, 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, controls the air compressor to continue running or stop, controls the opening degree of the second flow path in the oxygen production and fresh air mixing mode, and controls the oxygen production module to continue running or stop in the single oxygen production mode or the oxygen production and fresh air mixing mode, and further comprises a process of adjusting the oxygen content parameter in the oxygen production and fresh air mixing mode, specifically as follows:

[0140] The control unit 104 is specifically further configured to determine the size relationship of 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 it is determined that the oxygen regulation mode of the air conditioner is the oxygen production and fresh air mixing mode. The specific functions and processes of the control unit 104 are also described with reference to step S410.

[0141] The control unit 104 is specifically further configured to control the opening degree of the second flow path to be a first set opening degree 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 processes of the control unit 104 are also described with reference to step S420.

[0142] The control unit 104 is specifically further configured to control the opening degree of the second flow path to be a second set opening degree 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 degree is less than the lower limit of the first set opening degree. The specific functions and processes of the control unit 104 are also described with reference to step S430.

[0143] The control unit 104 is specifically further configured to control the opening degree of the second flow path to be a third set opening degree 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 degree is less than the lower limit of the second set opening degree. The specific functions and processes of the control unit 104 are also described with reference to step S440.

[0144] The control unit 104 is further configured to, if it is determined that the indoor oxygen content parameter of the air conditioner is not equal to the set oxygen content parameter, maintain the first flow path open and at a set maximum opening, maintain the second flow path open and at a set maximum opening, and, if the oxygen production module includes a molecular sieve oxygen production tower four-way valve, control the molecular sieve oxygen production tower four-way valve to continue operating, control the air compressor to continue operating, 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. The specific functions and processing of the control unit 104 are further described 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 the molecular sieve oxygen tower four-way valve, if the oxygen production module includes the 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 further described in step S460.

[0146] like Figure 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 human living area 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 its oxygen concentration, that is, the set oxygen concentration, is generally not less than the outdoor oxygen concentration. Therefore, the following three situations arise:

[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; the right opening of the diverter valve is [60%; 80%).

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

[0150] With the dynamic oxygen production, the indoor air quality is improved, and the set oxygen concentration and the indoor detected oxygen concentration are compared: if the indoor oxygen concentration reaches the set oxygen concentration, it is indicated that the overall quality of the indoor environment meets the set requirement, and the air compressor is stopped; if not, it continues to run. In this way, in the fresh air + oxygen production mode, the indoor oxygen concentration is dynamically adjusted, the indoor air freshness is quickly adjusted, and dynamic adjustment is performed to accurately control the indoor oxygen content parameter and improve the indoor comfort.
