[0033] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present application.

[0034] The present application provides an air conditioner oxygen production control method, which is applied to the air conditioner. Figure 1 The air conditioner 10 comprises: an oxygen production module 101, an external circulation module 102 and an internal circulation module 103. The oxygen production module 101 has an oxygen production function; the external circulation module 102 is used to introduce outdoor air, purify the outdoor air and discharge it into the room; the internal circulation module 103 is used to purify and dehumidify the indoor air.

[0035] Exemplarily, in some embodiments, the oxygen production module 101 includes a filter (for performing secondary filtration on the air input from the air inlet), an air intake silencer, an air compressor, a molecular sieve and its control valve, a pressure regulating valve, an exhaust silencer and other components.

[0036] like Figure 2 As shown, the oxygen production module 101 may include an air inlet, an oxygen outlet, and a nitrogen outlet. The air inlet on the oxygen production module 101 is connected to the air inlet of the external circulation module 102 and the air inlet of the internal circulation module 103 through a pipeline and a valve, respectively, the oxygen outlet on the oxygen production module 101 is connected to the room through a pipeline, and the nitrogen outlet on the oxygen production module is connected to the outside through a pipeline.

[0037] Exemplarily, the oxygen production module can be implemented based on PSA oxygen production technology. The basic principle of PSA oxygen production technology is to use the difference in adsorption performance of nitrogen and oxygen in the air on zeolite molecular sieve (Zeolite Molecular Sieve, ZMS) due to different pressures to selectively adsorb and separate nitrogen and oxygen, that is, to adsorb nitrogen and other impurities to produce oxygen.

[0038] In practical applications, the oxygen production module can be installed in any type of air conditioner, such as a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner, or a ceiling air conditioner. The cabinet air conditioner includes an upper air duct component and a lower air duct component. According to the internal structural characteristics of some cabinet air conditioners, the oxygen production module can be installed in the lower air duct component.

[0039] Based on the above air conditioner, the embodiment of the present application provides an air conditioner oxygen production control method. Figure 3 FIG. 1 is a first flow chart of the oxygen production control method for an air conditioner in an embodiment of the present application. Figure 3 As shown, the method may specifically include:

[0040] Step 301: Collect outdoor environmental humidity;

[0041] In practical applications, the outdoor humidity value H is obtained through the outdoor humidity sensor 外 , according to H 外 Size selection of oxygen production module air inlet path, such as H 外 <H e1 (H e1 is the first humidity threshold), select the first air inlet path between the external circulation air inlet and the air inlet of the oxygen production module as the air inlet path of the oxygen production module; 外 ≥H e1 , select the second air inlet path between the internal circulation air inlet and the air inlet of the oxygen production module as the air inlet path of the oxygen production module.

[0042] Exemplarily, the air inlet on the oxygen production module 101 is connected to the air inlet of the external circulation module 102 and the air inlet of the internal circulation module 103 through a pipe and a valve. In practical applications, the switching of the air inlet path of the oxygen production module can be controlled by a valve.

[0043] Here, it is determined whether the outdoor environment humidity is less than the first humidity threshold value. If yes, step 302 is executed; if no, step 304 is executed.

[0044] It should be noted that the embodiment of the present application selects the air inlet path of the oxygen production module according to the outdoor environmental humidity. It can be understood that the oxygen production module preferentially selects the air inlet of the external circulation module, and the oxygen production module has a higher oxygen production efficiency when choosing to take in air from the outside.

[0045] Step 302: When the outdoor environment humidity is less than a first humidity threshold, the air inlet of the oxygen production module is controlled to be connected with the air inlet of the external circulation module to form a first air inlet path of the oxygen production module;

[0046] Step 303: start the oxygen production module to introduce air from the first air inlet path to perform oxygen production operation;

[0047] Here, before starting the oxygen production module, the external circulation module is also started. The external circulation module has an air purification function. When the external circulation module is working, the outdoor air is purified and then sent to the indoor and the air inlet of the oxygen production module. It can be understood that the purification submodule of the external circulation module is set in the first air inlet path.

[0048] In some embodiments, the external circulation module also has a dehumidification function. When the external circulation module is working, the outdoor air is dehumidified before being sent to the indoor and the air inlet of the oxygen production module. It can be understood that a dehumidification submodule of the external circulation module is provided in the first air inlet path. It should be noted that when the humidity of the outdoor air is high, the dehumidification effect of the external circulation module is poor. Therefore, the external circulation module may not have a dehumidification function.

[0049] In practical applications, after executing step 303, the outdoor environment humidity judgment operation may continue to be performed. If the external environment humidity is greater than or equal to the first humidity threshold, the oxygen production module switches the air inlet path from the first air inlet path to the second air inlet path during operation.

[0050] Step 304: When the outdoor environment humidity is greater than or equal to the first humidity threshold, the air inlet of the oxygen production module is controlled to be connected with the air inlet of the internal circulation module to form a second air inlet path of the oxygen production module;

[0051] Step 305: Start the oxygen production module and introduce air from the second air inlet path to perform oxygen production operation.

[0052] Here, before starting the oxygen production module, the internal circulation module is also started. The internal circulation module has air purification and dehumidification functions. When the internal circulation module is working, the indoor air is purified and dehumidified before being sent to the air inlet of the oxygen production module. It can be understood that the purification submodule and dehumidification submodule of the internal circulation module are arranged in the first air inlet path.

[0053] It should be noted that the external circulation module and the internal circulation module can be independently provided with respective purification submodules and dehumidification submodules.

[0054] The external circulation module and the internal circulation module can share the purification submodule to purify the outdoor air and indoor air respectively, or they can share the dehumidification submodule to purify the outdoor air and indoor air respectively. Exemplarily, the purification submodule can be a single high efficiency air filter (High efficiency particulate air filter, HEPA) net, or it can be composed of a HEPA net and other types of purification submodules (such as an activated carbon net, a dust collector), etc., to achieve the first-level purification of the air input to the oxygen production module; the dehumidification submodule can include a desiccant to achieve the first-level dehumidification of the air input to the oxygen production module; the PTC heating module is used to heat the air in the air duct cavity, increase the dew point, and accelerate dehumidification; the air duct cavity is also equipped with a humidity sensor to monitor the humidity of the outdoor fresh air before entering the air duct cavity.

[0055] In practical applications, after executing step 305, the outdoor environment humidity judgment operation may continue to be performed. If the outdoor environment humidity is less than the first humidity threshold, the oxygen production module switches the air inlet path from the second air inlet path to the first air inlet path during operation.

[0056] In some embodiments, the oxygen production module includes a dehumidification submodule and / or a purification submodule, which respectively perform secondary dehumidification and secondary purification on the air entering the oxygen production module, and then input the dehumidified and purified air into the molecular sieve of the oxygen production module. Exemplarily, the dehumidification submodule includes a desiccant, and the purification submodule includes an activated carbon net or an integrator.

[0057] By adopting the above technical solution, the oxygen production module and the internal and external circulation modules in the air conditioner are jointly controlled, the air inlet path is flexibly selected, the humidity of the air entering the oxygen production module is reduced, the oxygen production effect of the oxygen production module is ensured, and the service life is extended.

[0058] In order to better reflect the purpose of this application, further examples are given based on the above embodiments of this application. Figure 4 As shown, the method specifically includes:

[0059] Step 401: Collect outdoor environmental humidity;

[0060] Here, it is determined whether the outdoor environment humidity is less than the first humidity threshold value. If yes, step 402 is executed; if no, step 403 is executed.

[0061] Step 402: When the outdoor environment humidity is less than a first humidity threshold, the air inlet of the oxygen production module is controlled to be connected with the air inlet of the external circulation module to form a first air inlet path of the oxygen production module;

[0062] Step 403: When the outdoor environment humidity is greater than or equal to the first humidity threshold, the air inlet of the oxygen production module is controlled to be connected with the air inlet of the internal circulation module to form a second air inlet path of the oxygen production module;

[0063] Step 404: Obtain working state parameters of the centrifugal fan;

[0064] Step 405: the working state parameter indicates that the centrifugal fan is in a shutdown state, and the shutdown time is greater than or equal to the first time threshold, and the centrifugal fan and the heating module are started;

[0065] Step 406: After the heating module heats for a second time threshold, the heating module is turned off to discharge the trapped air in the air duct of the air conditioner;

[0066] When the centrifugal fan is in the shutdown state for a long time, the air in the air duct of the air conditioner will be stagnant, and the humidity of this part of the stagnant air is relatively high. Therefore, the air in the air duct is heated by the heating module to accelerate the air discharge speed and ensure that the air introduced during oxygen production is purified fresh air with appropriate humidity.

[0067] Here, steps 404 to 406 can be understood as oxygen production pretreatment operations performed before starting the oxygen production module. By performing the pretreatment operation, it is possible to prevent the air trapped in the air duct from entering the oxygen production module and affecting the oxygen production life and oxygen production effect.

[0068] Exemplarily, in other embodiments, before starting the oxygen production module, the method further includes: determining that the centrifugal fan is in a shutdown state and the shutdown time is less than a first time threshold, or the centrifugal fan is in a working state, and controlling the external circulation module to operate for a third time threshold;

[0069] Alternatively, it is determined that the centrifugal fan is in a shutdown state and the shutdown time is less than the first time threshold, or the centrifugal fan is in an operating state, and the internal circulation module is controlled to operate for a fourth time threshold.

[0070] Here, the third time threshold and the fourth time threshold may be equal or unequal.

[0071] That is to say, when the centrifugal fan is in a short-term shutdown state or working state, before starting the oxygen production module to start continuous oxygen production, the internal circulation module or the external circulation module (depending on the selected air inlet path) is allowed to run for a period of time, and the air is purified and dehumidified by the purification and dehumidification functions of the internal and external circulation modules, and then input into the oxygen production module to ensure the quality of the air input into the oxygen production module.

[0072] Step 407: Start the oxygen production module to introduce air from the selected first air inlet path or the second air inlet path to perform oxygen production operation.

[0073] In some embodiments, the oxygen production module includes a dehumidification submodule and / or a purification submodule, which respectively perform secondary dehumidification and secondary purification on the air entering the oxygen production module, and then input the dehumidified and purified air into the molecular sieve of the oxygen production module. Exemplarily, the dehumidification submodule includes a desiccant, and the purification submodule includes an activated carbon net or an integrator.

[0074] By adopting the above technical solution, the oxygen production module and the internal and external circulation modules in the air conditioner are jointly controlled, the air inlet path is flexibly selected, the humidity of the air entering the oxygen production module is reduced, the oxygen production effect of the oxygen production module is ensured, and the service life is extended.

[0075] In order to better reflect the purpose of this application, further examples are given based on the above embodiments of this application. Figure 5 As shown, the method specifically includes:

[0076] Step 501: Collect outdoor environmental humidity;

[0077] Step 502: When the outdoor environment humidity is greater than or equal to the first humidity threshold, the air inlet of the oxygen production module is controlled to be connected with the air inlet of the internal circulation module to form a second air inlet path of the oxygen production module;

[0078] Exemplarily, in some embodiments, before starting the oxygen production module, the method further includes: obtaining a working state parameter of the centrifugal fan; the working state parameter indicates that the centrifugal fan is in a shutdown state, and the shutdown time is greater than or equal to a first time threshold, and the centrifugal fan and the heating module are started; after the heating module is heated for a second time threshold, the heating module is turned off to discharge the stagnant air in the air duct of the air conditioner.

[0079] Exemplarily, in other embodiments, before starting the oxygen production module, the method further includes: determining that the centrifugal fan is in a shutdown state and the shutdown time is less than a first time threshold, or the centrifugal fan is in a working state, and controlling the external circulation module to operate for a third time threshold;

[0080] Alternatively, it is determined that the centrifugal fan is in a shutdown state and the shutdown time is less than the first time threshold, or the centrifugal fan is in an operating state, and the internal circulation module is controlled to operate for a fourth time threshold.

[0081] Here, the third time threshold and the fourth time threshold may be equal or unequal.

[0082] Step 503: Collect indoor environmental humidity;

[0083] Step 504: Determine whether the indoor humidity is less than the first humidity threshold. If not, execute step 505; if yes, execute step 506;

[0084] Step 505: When the indoor environmental humidity is greater than or equal to the first humidity threshold, the internal circulation module is controlled to perform a dehumidification operation, and the external circulation module is controlled to be in a closed state;

[0085] Here, when the indoor environmental humidity is greater than or equal to the first humidity threshold, the process returns to step 503 to continue monitoring the indoor environmental humidity until it is determined that the latest collected indoor environmental humidity is less than the first humidity threshold, and step 506 is executed.

[0086] Step 506: until the indoor environmental humidity is less than the first humidity threshold, control the internal circulation module to stop performing the dehumidification operation;

[0087] That is to say, when the outdoor environment humidity is high, the air inlet path of the oxygen production module is switched from the first air inlet path to the second air inlet path. Since the internal circulation module has a dehumidification function and the indoor air humidity is low, the oxygen production module can introduce indoor air for oxygen production.

[0088] It can be understood that when the indoor environmental humidity is greater than or equal to the first humidity threshold, the process returns to step 503 to continue the dehumidification operation.

[0089] Here, step 503 to step 506 can be understood as an oxygen production pretreatment operation performed before starting the oxygen production module, and the air humidity is reduced by performing the pretreatment operation.

[0090] Exemplarily, in some embodiments, before starting the oxygen production module and introducing air from the second air inlet path to perform the oxygen production operation, the method also includes: controlling the internal circulation module to perform an air purification operation; collecting the indoor environment particle matter index; when the indoor environment particle matter index is less than the first index threshold, controlling the internal circulation module to stop performing the purification operation.

[0091] It can be understood that when the indoor environment particle index is greater than or equal to the first index threshold, the internal circulation module is controlled to continue to perform the purification operation until the indoor environment particle index is less than the first index threshold.

[0092] Here, the first index threshold value can be set according to the upper limit value of the particle index allowed by the molecular sieve in the oxygen production module, so as to ensure that the air entering the molecular sieve will not affect the adsorption capacity of the molecular sieve.

[0093] Here, it can also be understood as the oxygen production pretreatment operation performed before starting the oxygen production module. By performing the pretreatment operation, the air particulate matter index is reduced and the air quality is improved.

[0094] Step 507: Start the oxygen production module and introduce air from the second air inlet path to perform oxygen production operation.

[0095] In some embodiments, the oxygen production module includes a dehumidification submodule and / or a purification submodule, which respectively perform secondary dehumidification and secondary purification on the air entering the oxygen production module, and then input the dehumidified and purified air into the molecular sieve of the oxygen production module. Exemplarily, the dehumidification submodule includes a desiccant, and the purification submodule includes an activated carbon net or an integrator.

[0096] By adopting the above technical solution, the oxygen production module and the internal and external circulation modules in the air conditioner are jointly controlled, the air inlet path is flexibly selected, the humidity of the air entering the oxygen production module is reduced, the oxygen production effect of the oxygen production module is ensured, and the service life is extended.

[0097] In order to better reflect the purpose of this application, further examples are given based on the above embodiments of this application. Figure 6 As shown, the method specifically includes:

[0098] Step 601: Collect outdoor environmental humidity;

[0099] Step 602: When the outdoor environment humidity is greater than or equal to the first humidity threshold, the air inlet of the oxygen production module is controlled to be connected with the air inlet of the internal circulation module to form a second air inlet path of the oxygen production module;

[0100] Here, when the outdoor environment humidity is less than the first humidity threshold, the air inlet of the oxygen production module is controlled to be connected with the air inlet of the external circulation module to form a first air inlet path of the oxygen production module.

[0101] For example, H 外 <H e1 , continue to use the first air inlet path to maintain oxygen production; H 外 ≥H e1 , oxygen production is suspended, the internal circulation air inlet is selected as the air inlet path of the oxygen production module, and the oxygen production pretreatment work before the oxygen production module is re-executed.

[0102] Step 603: Start the oxygen production module to introduce air from the second air inlet path to perform oxygen production operation;

[0103] Step 604: Collect indoor environmental humidity;

[0104] Step 605: When the indoor environmental humidity is less than the first humidity threshold and greater than the second humidity threshold, and the outdoor environmental humidity is less than the third humidity threshold, the air inlet path of the oxygen production module is switched from the second air inlet path to the first air inlet path;

[0105] Here, the first humidity threshold is greater than the second humidity threshold, and the second humidity threshold is greater than or equal to the third humidity threshold.

[0106] It should be noted that the indoor environment humidity and outdoor environment humidity are collected in real time at this time. When the oxygen production module uses the second air inlet path to introduce air, it can also judge whether it is necessary to switch the oxygen production module from the second air inlet path to the first air inlet path according to the current indoor environment humidity and outdoor environment humidity. That is, when the outdoor environment humidity is less than the third humidity threshold, the switch is performed; otherwise, the second air inlet path is continued to be used without switching.

[0107] Similarly, when the oxygen production module uses the first air inlet path to introduce air, it can continue to determine whether it is necessary to switch the oxygen production module from the first air inlet path to the second air inlet path according to the current outdoor ambient humidity.

[0108] Step 606: When the indoor environment humidity is less than the first humidity threshold and greater than the second humidity threshold, and the outdoor environment humidity is greater than or equal to the third humidity threshold, the internal circulation module is controlled to perform a dehumidification operation.

[0109] In some embodiments, when the indoor environmental humidity is less than a second humidity threshold, the internal circulation module is controlled to stop the dehumidification operation.

[0110] For example, in (H e1 -△h1) <H 内 <H e1 When H 外 <(H e1 -△h2), switch to the first air inlet path to maintain oxygen production; at (H e1 -△h1) <H 内 <H e1 When H 外 ≥(H e1 -△h2), continue to use the second air inlet path to maintain oxygen production, while the dehumidification function of the internal circulation module is turned off until H 内 <(H e1 -△h1) and then stop dehumidification. The above △h2≥△h1. Here, H e1 Equivalent to the first humidity threshold, (H e1 -△h1) is equivalent to the second humidity threshold, (H e1 -△h2) is equivalent to the third humidity threshold.

[0111] In some embodiments, the oxygen production module includes a dehumidification submodule and / or a purification submodule, which respectively perform secondary dehumidification and secondary purification on the air entering the oxygen production module, and then input the dehumidified and purified air into the molecular sieve of the oxygen production module. Exemplarily, the dehumidification submodule includes a desiccant, and the purification submodule includes an activated carbon net or an integrator.

[0112] By adopting the above technical solution, by further setting the switching conditions of the air inlet path, the accuracy of the air inlet path switching control can be improved, and excessive loss caused by frequent switching can be avoided. The oxygen production module and the internal and external circulation modules in the air conditioner are jointly controlled to flexibly select the air inlet path, reduce the humidity of the air entering the oxygen production module, ensure the oxygen production effect of the oxygen production module, and extend the service life.

[0113] In order to implement the method of the embodiment of the present application, the embodiment of the present application also provides an air conditioner oxygen production control device, which is applied to the air conditioner. The air conditioner includes: an oxygen production module, an external circulation module and an internal circulation module; Figure 7 As shown, the device 70 includes:

[0114] A collection unit 701 is used to collect outdoor environmental humidity;

[0115] The control unit 702 is used to control the air inlet of the oxygen production module to be connected with the air inlet of the external circulation module to form a first air inlet path of the oxygen production module when the outdoor environment humidity is less than the first humidity threshold; the processing unit 703 is used to start the oxygen production module and introduce air from the first air inlet path to perform the oxygen production operation;

[0116] or,

[0117] The control unit 702 is used to control the air inlet of the oxygen production module to be connected with the air inlet of the internal circulation module to form a second air inlet path of the oxygen production module when the outdoor environment humidity is greater than or equal to the first humidity threshold;
