[0061] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0064] When the oxygen-generating air conditioner in the prior art generates oxygen, the oxygen generator generates oxygen at high power. Since the oxygen generation amount of the oxygen generator is much greater than the oxygen amount absorbed by the user, it leads to oxygen waste. Moreover, long-term high-power operation will also consume more energy and shorten the service life of the oxygen generator.

[0065] In order to solve the above technical problems, this embodiment proposes a control method, a control device and an oxygen-generating air conditioner. The oxygen-generating air conditioner includes an air supply mode, and the control method includes:

[0066] In air supply mode, obtain the indoor oxygen concentration of the indoor environment where the indoor unit is located;

[0067] When the indoor oxygen concentration is lower than the maximum value of the preset oxygen concentration range, the actual oxygen production power of the oxygen concentrator is determined according to the indoor oxygen concentration, the preset oxygen concentration range and the preset oxygen production power of the oxygen concentrator;

[0068] Control the oxygen generator to operate at the actual oxygen production power.

[0069] This embodiment monitors the indoor oxygen concentration of the indoor environment where the indoor unit is located, and when the indoor oxygen concentration level is low, determines the oxygen production power according to the indoor oxygen concentration, the preset oxygen concentration range and the preset oxygen production power, so that the oxygen generator can use different oxygen production powers to produce oxygen at different indoor oxygen concentration levels, thereby avoiding oxygen waste caused by excessive oxygen production and avoiding the oxygen generator from operating at a high oxygen production power for a long time, and at the same time extending the service life of the oxygen generator.

[0070] First, the execution body of the oxygen-generating air conditioner of this embodiment is briefly introduced.

[0071] The oxygen-generating air conditioner includes an indoor unit, an outdoor unit and an oxygen generator, wherein the indoor unit includes an inner casing, an air supply duct, an inner fan and an indoor heat exchanger, and the inner casing is provided with an air inlet and an air outlet, wherein, for a wall-mounted indoor unit, the air inlet is generally provided at the top of the inner casing, and the air outlet is provided at the lower side of the front of the inner casing, but the setting position of the air inlet is not limited thereto and can be flexibly designed as required. The arrangement of the inner fan, the air supply duct and the indoor heat exchanger is similar to that of the indoor unit of a conventional air conditioner, and will not be described in detail here.

[0072] The outdoor unit includes an outer casing, a compressor, an outdoor fan and an outdoor heat exchanger. The arrangement of the outer casing, the compressor, the outdoor fan and the outdoor heat exchanger is similar to that of the outdoor unit of a conventional air conditioner and will not be repeated here.

[0073] The oxygen concentrator includes components such as an air compressor, a filter element, and a molecular sieve. The specific structure of the oxygen concentrator is prior art and will not be described in detail here. The oxygen concentrator is provided with an oxygen outlet, which is connected to the air inlet and / or air outlet of the indoor unit through an oxygen delivery pipeline, so that the oxygen generated by the oxygen concentrator can be blown into the indoor environment along with the air flow blown out of the air outlet of the indoor unit. In a preferred embodiment, the oxygen outlet of the oxygen concentrator is connected to the air inlet of the indoor unit, so that the oxygen generated by the oxygen concentrator can be blown into the room after heat exchange in the indoor heat exchanger, thereby improving the comfort of the indoor environment.

[0074] The oxygen concentrator can be installed in the indoor environment where the indoor unit is located, or in the outdoor environment where the outdoor unit is located. Preferably, the oxygen concentrator is installed in the outdoor unit to reduce the impact of the noise when the oxygen concentrator is started on the users in the indoor environment. Further preferably, the oxygen concentrator is integrated with the outdoor unit to reduce the space occupied by the oxygen concentrator.

[0075] The oxygen-generating air conditioner further includes an oxygen concentration detection device, which is disposed at the indoor unit and away from the oxygen outlet of the oxygen delivery pipeline, so as to accurately detect the indoor oxygen concentration of the indoor environment in which the indoor unit is located. In one example, the oxygen outlet is connected to the air outlet through the oxygen delivery pipeline, and the oxygen concentration detection device is disposed at the air inlet.

[0076] The oxygen-generating air conditioner also includes a millimeter-wave radar detection device to detect the horizontal distance and azimuth angle of the user relative to the indoor unit, wherein the azimuth angle is the angle of the line between the user's position and the air outlet of the indoor unit relative to a plane perpendicular to the length direction of the indoor unit. Figure 6 , Figure 6The α in the figure is the azimuth angle. For a wall-mounted indoor unit, the horizontal distance is the vertical distance of the user relative to the wall on which the indoor unit is installed. For a cabinet-type air-conditioning indoor unit, the horizontal distance is the vertical distance between the user and the cabinet-type air-conditioning indoor unit. In other achievable methods, the detection of the horizontal distance and the azimuth angle can be performed using a distance sensor and an angle sensor, and is not limited to the millimeter wave radar detection device proposed in this embodiment.

[0077] The control method of this embodiment is described in detail below in conjunction with the accompanying drawings. The following implementation modes and examples may be combined with each other if there is no conflict.

[0078] This embodiment proposes a control method for an oxygen-generating air conditioner. Figure 1 The control method comprises the following steps:

[0079] S11. In air supply mode, obtain the indoor oxygen concentration of the indoor environment where the indoor unit is located.

[0080] Specifically, the oxygen-generating air conditioner can execute the air supply mode in the cooling mode, the heating mode or the dehumidification mode. The air supply mode can be executed according to the control instruction of the user, or it can be executed after the preset implementation conditions are met.

[0081] In one example, combining Figure 7 , the air supply mode is entered when the following conditions are met: the number of users in the indoor environment where the indoor unit is located is less than or equal to the preset number of users, and when the preset number of users is greater than 1, the difference between the azimuth angle of the target user and the azimuth angle of any other user in the indoor environment is less than the preset angle. The target user may be the user closest to the indoor unit, or the user farthest from the air conditioner, or the user in the middle of multiple users, which is not specifically limited here. The range of the preset number of users is, for example, greater than 1 and less than or equal to 4.

[0082] When the above conditions are met, it means that the number of users in the indoor environment is small and relatively concentrated. At this time, the oxygen-rich airflow blown out by the indoor unit can be blown accurately to the area where users gather by executing the air supply mode, while there is no need to transport oxygen-rich airflow to the area where there are no users in the indoor environment. In this way, the temperature and oxygen concentration in the user gathering area can be quickly brought to an optimal level, thereby improving the user's physical comfort.

[0083] In the air supply mode, the indoor oxygen concentration of the indoor environment where the indoor unit is located is first obtained in real time or periodically, so that it can be determined whether the indoor environment is an oxygen-rich environment or an oxygen-deficient environment based on the indoor oxygen concentration and the preset oxygen concentration range, and then different control strategies can be adopted.

[0084] S12, when the indoor oxygen concentration is lower than the maximum value of the preset oxygen concentration range, determining the actual oxygen production power of the oxygen concentrator according to the indoor oxygen concentration, the preset oxygen concentration range and the preset oxygen production power of the oxygen concentrator;

[0085] Specific, combined Figure 7 After obtaining the indoor oxygen concentration, the indoor oxygen concentration is compared with the preset oxygen concentration range. The maximum value of the preset oxygen concentration range is the optimal oxygen concentration that is most suitable for the user's body. When the indoor oxygen concentration is greater than or equal to the maximum value of the preset oxygen concentration range, it means that the current indoor environment is in an oxygen-rich environment and there is no need to start the oxygen generator to generate oxygen. When the indoor oxygen concentration is less than the maximum value of the preset oxygen concentration range, it means that the indoor environment may be in an oxygen-deficient state. At this time, the oxygen generator needs to be started to make the oxygen concentration of the indoor environment reach the optimal oxygen concentration suitable for the user's body.

[0086] However, different indoor oxygen concentration levels represent the degree of oxygen deficiency in the indoor environment. If the oxygen generator is controlled to produce oxygen at the same oxygen production power regardless of how high the indoor oxygen concentration is, then using a higher oxygen production power to produce oxygen when the indoor oxygen deficiency level is low will cause a waste of oxygen and energy. Alternatively, using a lower oxygen production power to produce oxygen when the indoor oxygen deficiency level is high will cause the indoor oxygen concentration to take a longer time to reach the optimal oxygen concentration, reducing the user experience.

[0087] Therefore, after determining that the indoor environment is in an oxygen-deficient state, this embodiment further determines the actual oxygen production power of the oxygen concentrator according to the indoor oxygen concentration, the preset oxygen concentration range and the preset oxygen production power of the oxygen concentrator, so as to adopt different oxygen production powers to produce oxygen according to different indoor oxygen concentration levels, so that the indoor environment can quickly reach the optimal oxygen concentration, avoid long-term operation of the oxygen concentrator, and extend the service life of the oxygen concentrator.

[0088] S13, controlling the oxygen generator to operate at the actual oxygen production power.

[0089] The control method of this embodiment can effectively reduce the running time of the oxygen concentrator, achieve energy saving effect, and increase the service life of the oxygen concentrator. In addition, in the air supply mode, the oxygen-enriched air flow can be blown accurately to the user's position, improving the user's physical comfort.

[0090] In an optional implementation, the preset oxygen concentration range includes a first threshold value and a second threshold value, the first threshold value> the second threshold value, the first threshold value represents the expected upper limit value of the indoor oxygen concentration, and the second threshold value represents the expected lower limit value of the indoor oxygen concentration. Figure 2 The flowchart of the present invention is to determine the actual oxygen production power of the oxygen concentrator according to the indoor oxygen concentration, the preset oxygen concentration range and the preset oxygen production power of the oxygen concentrator, including the following steps:

[0091] S21, determining a power adjustment coefficient of the oxygen concentrator according to the indoor oxygen concentration, the first threshold value, and the second threshold value;

[0092] S22. Determine the actual oxygen production power according to the product of the power adjustment coefficient and the preset oxygen production power.

[0093] Specifically, the first threshold is the maximum value of the preset oxygen concentration range, and the second threshold is the minimum value of the preset oxygen concentration range. After the power adjustment coefficient is determined, the actual power is the product of the power adjustment coefficient and the preset oxygen production power of the oxygen concentrator. The preset oxygen production power can be the power set by the user or the maximum power of the oxygen concentrator, which is not specifically limited here.

[0094] In one example, the power adjustment coefficient of the oxygen generator is determined according to the indoor oxygen concentration, the first threshold value, and the second threshold value, including: the power adjustment coefficient is a function of the indoor oxygen concentration, the first threshold value, and the second threshold value, and: the greater the indoor oxygen concentration, the smaller the power adjustment coefficient; the greater the second threshold value, the greater the power adjustment coefficient, because the greater the indoor oxygen concentration, the lighter the degree of hypoxia in the indoor environment, and at this time, only a lower oxygen production power is needed, so the power adjustment coefficient is smaller. The greater the second threshold value, the more likely the indoor environment is to be in a more severe degree of hypoxia, and therefore the higher the oxygen production power required.

[0095] And / or, the power adjustment factor satisfies the formula: Wherein: K1 is the power adjustment coefficient, Q0 is the first threshold, Q1 is the second threshold, and Q is the indoor oxygen concentration.

[0096] When the indoor oxygen concentration is less than the first threshold Q0 and greater than or equal to the second threshold Q1, it means that the degree of indoor oxygen deficiency is relatively light. At this time, K1 is a value less than 1, and the actual oxygen production power is less than the preset oxygen production power; when the indoor oxygen concentration is less than the second threshold Q0, it means that the degree of indoor oxygen deficiency is relatively heavy. At this time, K1 is a value greater than 1, and the actual oxygen production power is greater than the preset oxygen production power.

[0097] This embodiment determines different power adjustment coefficients according to the indoor oxygen concentration, the first threshold value and the second threshold value, so as to more accurately regulate the power of the oxygen concentrator, further shorten the working time of the oxygen concentrator, reduce energy consumption and extend the service life of the oxygen concentrator.

[0098] In an optional implementation, referring to Figure 3 The control method further comprises the following steps:

[0099] S31. In the air supply mode, the azimuth angle and horizontal distance of the user relative to the indoor unit are also obtained;

[0100] S32, determining the air supply distance of the indoor unit according to the azimuth angle and the horizontal distance;

[0101] S33, controlling the speed of the internal fan according to the horizontal distance, the air supply distance and the preset speed of the internal fan.

[0102] Specifically, in the long-distance air supply mode, the air supply distance of the user is determined by obtaining the azimuth angle and horizontal distance of the user relative to the indoor unit in real time or periodically. Since the azimuth angle is the angle between the line between the user's position and the air outlet of the indoor unit and the plane perpendicular to the length direction of the indoor unit, Figure 6 , Figure 6 The α in the equation is the azimuth angle. The horizontal distance is the vertical distance between the user and the wall on which the wall-mounted indoor unit is installed, or the vertical distance between the user and the indoor unit of the cabinet air conditioner. The air supply distance is the straight-line distance between the air outlet of the indoor unit and the user. Therefore, the air supply distance of the indoor unit can be determined by trigonometric functions.

[0103] After determining the air supply distance, the speed of the indoor fan is regulated according to the air supply distance so that the air blown out from the air outlet of the indoor unit can reach the user's location.

[0104] In an optional implementation, referring to Figure 4 The flow chart of the invention controls the speed of the internal fan according to the horizontal distance, the air supply distance and the preset speed of the oxygen air conditioner, including the following steps:

[0105] S41, determining a speed adjustment coefficient according to a preset speed and air supply distance;

[0106] S42, controlling the speed of the internal fan according to the speed adjustment coefficient and the horizontal distance.

[0107] Specifically, the preset speed is the speed set by the user. After determining the preset speed and the air supply distance, the speed adjustment coefficient is first determined according to the preset speed and the air supply distance. In one example, the speed adjustment coefficient is determined according to the preset speed and the air supply distance, including: the speed adjustment coefficient is a function of the preset speed and the air supply distance, and: the larger the preset speed, the larger the speed adjustment coefficient; the larger the air supply distance, the smaller the speed adjustment coefficient; and / or, the speed adjustment coefficient satisfies the formula: K2=R0 / L, wherein: K2 is the speed adjustment coefficient, R0 is the preset speed, and L is the air supply distance.

[0108] After the speed adjustment coefficient is determined, the speed of the internal fan can be determined according to the speed adjustment coefficient. In one example, the speed of the internal fan is controlled according to the speed adjustment coefficient and the horizontal distance, including: the speed of the internal fan is a function of the speed adjustment coefficient and the horizontal distance, and: the larger the speed adjustment coefficient, the larger the speed of the internal fan; the larger the horizontal distance, the larger the speed of the internal fan; and / or, the speed of the internal fan satisfies the formula: R = R min +K2·s, where: R is the speed of the internal fan, K2 is the speed adjustment coefficient, s is the horizontal distance, Rmin Minimum speed of the internal fan.

[0109] The method for determining the speed of the indoor fan in this embodiment can ensure that the oxygen-rich airflow blown out from the air outlet of the indoor unit under the power of the indoor fan can smoothly reach the user's location, thereby ensuring the oxygen concentration and air conditioning effect at the user's location.

[0110] In an optional implementation, referring to Figure 5 The control method further comprises the following steps:

[0111] S51. In air supply mode, the azimuth angle of the user relative to the indoor unit is also obtained;

[0112] S52: Control the air sweeping angle of the indoor unit according to the azimuth angle so that the airflow blows toward the target position.

[0113] Specifically, in order to ensure that the airflow can be blown to the user's location more accurately, the sweeping angle of the indoor unit needs to be regulated. In this embodiment, the sweeping angle of the indoor unit is controlled by obtaining the azimuth angle of the user relative to the indoor unit so that the airflow can be blown to the target location. The target location is related to the air conditioning mode of the oxygen-generating air conditioner, user attributes and / or user needs.

[0114] In one example, when the oxygen-generating air conditioner operates in cooling mode, the air sweeping angle of the indoor unit is adjusted so that the air flow blows above the user's head; when the oxygen-generating air conditioner operates in heating mode, the air sweeping angle of the indoor unit is adjusted so that the air flow blows toward the user's feet.

[0115] In one example, when the user is a young person, the air sweeping angle of the indoor unit is adjusted so that the airflow blows toward the user's body; when the user is an elderly person or a child, the air sweeping angle of the indoor unit is adjusted so that the airflow blows near the user's location.

[0116] In one example, the user can also directly set the target position. The user can set the target position to the feet, body, head, or above the user's head, etc. as needed, and then adjust the wind sweeping angle of the indoor unit to make the air flow blow to the target position set by the user.

[0117] In a specific implementation, combining Figure 7 In the flowchart, the azimuth angle of the user relative to the indoor unit is α. When α is greater than 0, it means that the user is on the right side of the indoor unit, the indoor unit is controlled to sweep air to the right, and the sweeping blades are rotated by an angle α; when α is less than 0, it means that the user is on the left side of the indoor unit, the indoor unit is controlled to sweep air to the left, and the sweeping blades are rotated by an angle α.

[0118] The manner of determining the fan speed and the wind sweeping angle in this embodiment is also related to the number of users in the indoor environment.

[0119] In one example, combining Figure 7 Flow chart, when there is only one user in the indoor environment, the fan speed is determined directly according to the azimuth angle and horizontal distance of the user relative to the indoor unit through the fan speed calculation formula, and the wind sweeping angle of the indoor unit is determined according to the azimuth angle of the user.

[0120] In one example, combining Figure 7 , when there are multiple users in the indoor environment, the actual azimuth angle and actual horizontal distance of each user are determined respectively, and then the fan speed is determined by the fan speed calculation formula according to the maximum horizontal distance among multiple users and the azimuth angle of the target user, and the wind sweeping angle of the indoor unit is determined according to the azimuth angle of the target user, so that the area where the airflow blows can cover all users.

[0121] In the air supply mode, this embodiment can realize that the oxygen-rich airflow is blown accurately to the user's area, so that the user's area is at an optimal oxygen concentration level and a suitable temperature level. In addition, it also reduces the operating time of the oxygen generator, reduces energy consumption, and extends its service life.

[0122] In an optional implementation, combining Figure 7 The flow chart shows that the oxygen-generating air conditioner also includes a whole-house oxygen-enriched mode, and the control method includes: in the whole-house oxygen-enriched mode, controlling the oxygen generator to start with a preset oxygen-generating power; when the indoor oxygen concentration reaches the target oxygen concentration, controlling the oxygen generator to stop.

[0123] Specifically, the oxygen-generating air conditioner can execute the whole-house oxygen-enriched mode in the cooling mode, heating mode or dehumidification mode. The whole-house oxygen-enriched mode can be executed according to the user's control instruction or after the preset implementation conditions are met.

[0124] In one example, combining Figure 7 , the whole-house oxygen enrichment mode is entered when the following conditions are met: the number of users in the indoor environment where the indoor unit is located is greater than the preset number; or, when the preset number is greater than 1, the difference between the azimuth angle of the target user and the azimuth angle of at least one of the other users is less than the preset angle. The target user may be the user closest to the indoor unit, or the user farthest from the air conditioner, or the user in the middle of multiple users, which is not specifically limited here. The range of the preset number of people is, for example, greater than 1 and less than or equal to 4.

[0125] When the above conditions are met, it means that the number of users in the indoor environment is relatively scattered, and the air outlet range of the indoor unit cannot cover all users. At this time, the whole-house oxygen enrichment mode is run to make the entire indoor environment at the target oxygen concentration with an optimal oxygen concentration. Therefore, the oxygen generator is controlled to start with a preset oxygen production power to increase the rate of increase of the indoor oxygen concentration. The preset oxygen production power can be the power set by the user or the maximum power of the oxygen generator, which is not specifically limited here.

[0126] In an optional implementation, combining Figure 7 The control method further includes: in the whole-house oxygen enrichment mode, the indoor unit is further controlled to sweep air left and right at a preset sweeping angle, the preset sweeping angle being greater than the minimum sweeping angle of the indoor unit, so as to improve the uniformity of the oxygen-enriched air flow in the indoor environment. And / or, the indoor fan of the indoor unit is controlled to run at a preset speed to further improve the uniformity of the oxygen-enriched air flow in the indoor environment. The preset speed is, for example, a speed set by the user.

[0127] In an optional implementation, referring to Figure 7 After adjusting the oxygen generator power, fan speed and sweep angle, the running time t of the oxygen generator air conditioner needs to be monitored. When the running time is greater than the set time t0, the running time is reset to zero and the number of users in the indoor environment is re-detected. Figure 7 The flowchart re-executes the subsequent process.

[0128] In general, in the air supply mode, this embodiment controls the oxygen production power of the oxygen generator by combining the indoor oxygen concentration, the preset oxygen concentration range and the preset oxygen production power, so as to realize oxygen production when the indoor oxygen content is low, and also matches different oxygen production powers according to the indoor oxygen concentration, thereby reducing oxygen waste, reducing oxygen production energy consumption, and extending the service life of the oxygen generator. In addition, by further adjusting the speed and sweeping angle of the internal fan according to the position of the user relative to the indoor unit, the oxygen-enriched airflow can be accurately blown to the user's position, ensuring that the oxygen concentration and temperature at the user's position are appropriate, and improving the user experience.
