[0050] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts fall within the protection scope of the present invention.

[0051] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0052] As Figure 1 and Figure 2 shown, an exemplary embodiment of the present invention provides an air conditioner. The air conditioner includes an oxygen-enriched component 1 and a pressure regulating component 2. The oxygen-enriched component 1 includes a housing 11 and a plurality of hollow tubular fiber membranes 12 disposed in the housing 11. Among them, the plurality of hollow tubular fiber membranes 12 are arranged in an array in the housing 11.

[0053] Referring to Figure 1 and Figure 2 shown, the housing 11 has a hollow internal structure. The shape of the housing 11 may include but is not limited to a cuboid, a cylinder or an ellipsoid, etc. An air inlet 111 for air to enter is provided on the housing 11, and at least a first outlet 112 and a second outlet 113 are provided on the housing 11.

[0054] In one example, the air inlet 111 may be provided on the top surface of the housing 11. Among them, a primary filtration unit 3 and a gas treatment unit 4 are provided in the upstream pipeline of the air inlet 111. The primary filtration unit 3 is used for preliminarily filtering the air entering the housing 11.

[0055] In some embodiments, the primary filtration unit 3 may include but is not limited to a primary air filter element. Among them, a temperature and humidity sensor may also be provided in the upstream pipeline of the primary air filter element to facilitate monitoring the temperature and humidity of the air entering the housing 11.

[0056] The gas treatment unit 4 is arranged on the pipeline between the primary filtration unit 3 and the air inlet 111, and the gas treatment unit 4 is used to compress the filtered air. Among them, the gas treatment unit 4 may include, but is not limited to, a compressor or a compression pump, etc.

[0057] The second outlet 113 can be arranged on the bottom surface of the housing 11 and is arranged opposite to the air inlet 111. The second outlet 113 is used to guide nitrogen or condensed water to the outside. The first outlet 112 can be arranged on the side wall of the housing 11 and is used to guide the oxygen or oxygen-enriched air generated by the oxygen enrichment component into the room to adjust the oxygen concentration in the room.

[0058] Along the air flow direction, when the compressed hot air enters the housing 11 through the air inlet 111, since the temperature inside the housing 11 is lower than the temperature of the hot air, therefore, the moisture in the air will condense and condensed water will be separated out. The condensed water can be discharged to the outside of the oxygen enrichment component 1 through the second outlet 113.

[0059] A plurality of hollow tubular fiber membranes 12 are arranged in an array in the housing 11. Among them, the plurality of hollow tubular fiber membranes 12 can be arranged in a rectangular array or in a circumferential array.

[0060] The pressure regulating member 2 is arranged on the downstream pipeline of the second outlet 113. The pressure regulating member 2 is used to regulate the pressure in the oxygen enrichment component 1. Specifically, the pressure regulating member 2 is used to regulate the pressure inside the housing 11. In some examples, the pressure regulating member 2 may include, but is not limited to, a back pressure valve, etc. Among them, when the opening of the back pressure valve is adjusted to the maximum, there is no pressure at the end side of the first outlet 112, and air can enter from the air inlet end of the hollow tubular fiber membrane 12 and flow out from the other end of the hollow tubular fiber membrane 12. When the opening of the back pressure valve is less than the maximum opening, at this time, the gas flow rate in the downstream pipeline of the first outlet 112 decreases, causing the pressure inside the housing 11 to increase, and the oxygen in the air overflows from the hollow tubular fiber membrane 12 and forms oxygen-enriched air. The oxygen-enriched air flows out from the first outlet 112 and is transported into the room to adjust the oxygen concentration in the room. And the nitrogen in the air directly moves along the extension direction of the hollow tubular fiber membrane 12 until it is discharged from the second outlet 113 and is finally guided to the outside through the back pressure valve.

[0061] In order to obtain the flow rate of the oxygen-enriched air in the first outlet 112, a flow sensor 5 is arranged in the downstream pipeline of the first outlet 112. And an oxygen concentration sensor 6 can be arranged in the downstream pipeline of the flow sensor 5 to monitor the oxygen concentration in the oxygen-enriched air by using the oxygen concentration sensor 6, so as to facilitate the indoor personnel to monitor and control the indoor oxygen concentration.

[0062] Among them, the pipelines between the various components in this example are all connecting pipelines.

[0063] In the air conditioner of this embodiment, the filtered air is delivered to the gas treatment unit 4 and compressed into hot air by the gas treatment unit 4. Then, the hot air enters the housing 11 through the connecting pipe. Since the temperature in the housing 11 is lower than the temperature of the hot air, the moisture in the hot air is precipitated to form condensed water. Among them, the condensed water can be guided outdoors. And the air after condensation enters the hollow tubular fiber membrane 12. Under the adjustment of the pressure regulating member 2, by controlling the pressure in the oxygen enrichment component 1, the oxygen in the air is separated. Finally, nitrogen is delivered outdoors through the second outlet 113, and oxygen is delivered indoors through the first outlet 112, thereby increasing the oxygen content in the room, realizing the adjustment of the indoor oxygen concentration and the discharge of condensed water, and then realizing the self-cleaning process of the air conditioner, eliminating the influence of condensed water on the oxygen concentration adjustment, and improving the experience of the air conditioner.

[0064] Since only the cooperation of the hollow tubular fiber membrane 12 and the back pressure valve is required in the air conditioner of the present invention to realize the process of adjusting the indoor oxygen concentration and discharging condensed water, the energy consumption of the air conditioner is effectively reduced. At the same time, the structural composition for oxygen concentration adjustment and condensed water discharge in this air conditioner is simple, the structure is compact, and the occupied volume is small. It can be integrated into the air conditioner or other household electrical appliances, such as purifiers or cold fans. Or, it can also be directly installed in the user's room to achieve the same effect.

[0065] It should be noted that the condensed water can be discharged outdoors through the second outlet 113. Among them, the process of discharging the condensed water in the hollow tubular fiber membrane 12 outdoors is described in the embodiment of the following air conditioner condensed water treatment method.

[0066] As Figure 3 shown, an exemplary embodiment of the present invention provides an air conditioner condensed water treatment method, which includes the following steps:

[0067] Step S100: Perform a first evacuation treatment on the oxygen enrichment component to drain the condensed water in the oxygen enrichment component during the shutdown period outdoors through the second outlet.

[0068] Step S200: After the first evacuation treatment runs for a first preset time, control the oxygen enrichment component to operate in the oxygen generation mode to separate the oxygen in the air, and the oxygen is input into the room through the first outlet.

[0069] Step S300: Obtain the flow rate of oxygen in the first outlet.

[0070] Step S400: Selectively perform a first evacuation treatment on the oxygen enrichment component according to the magnitude relationship between the flow rate and the preset flow rate threshold range.

[0071] Step S500: After the oxygen generation mode ends, perform a second evacuation process on the oxygen enrichment component for a second preset time.

[0072] Refer to Figure 5 And in combination with Figure 4 As shown, during the air conditioner shutdown process, there may be condensate in the oxygen enrichment component 1. Therefore, before the air conditioner starts, the condensate in the oxygen enrichment component 1 needs to be removed to eliminate the influence of the condensate on the oxygen concentration regulation. Therefore, in step S100, before the air conditioner starts, first perform a first evacuation process on the oxygen enrichment component 1 to drain the condensate in the oxygen enrichment component 1 during the shutdown period to the outside through the second outlet 113. It should be noted that the first evacuation process can remove the condensate by using pressure. For example, the discharge of the condensate can be controlled by the opening degree of the back pressure valve (pressure regulating component). Or, the housing 11 is arranged vertically, the air inlet 111 is arranged on the top surface of the housing 11, and the second outlet 113 is arranged on the bottom surface of the housing 11 to utilize the gravity of the condensate itself and apply pressure to drain the condensate outside the oxygen enrichment component 1.

[0073] In step S200, when the first evacuation process runs for a first preset time T1, control the oxygen enrichment component 1 to run in the oxygen generation mode to separate the oxygen in the air passing through the oxygen enrichment component 1, and the separated oxygen is input into the room through the first outlet 112 to increase and adjust the oxygen concentration in the room. Among them, the first preset time T1 can be flexibly set according to the specific structure, specification size of the oxygen enrichment component 1 or the arrangement method of the hollow tubular fiber membrane 12. For example, the first preset time T1 can be 10s or 20s, etc., or the first preset time T1 can also be other values, which are not specifically limited here.

[0074] In step S300, the flow rate of the oxygen in the first outlet 112 can be obtained by the flow sensor 5 arranged in the downstream pipeline of the first outlet 112. At the same time, an oxygen concentration sensor 6 can be arranged in the downstream pipeline of the flow sensor 5 to monitor the concentration of the oxygen in the first outlet 112 by using the oxygen concentration sensor 6, which is convenient for the indoor personnel to monitor and control the oxygen concentration in the indoor air.

[0075] In step S400, after obtaining the flow rate of oxygen in the first outlet 112, the flow rate of the oxygen is compared with a preset flow rate threshold range. When the flow rate of oxygen is greater than the upper limit of the preset flow rate threshold range, it indicates that the content of condensed water in the hollow tubular fiber membrane 12 in the oxygen enrichment component 1 is small, and at this time, the first evacuation process is not required for the oxygen enrichment component 1. When the flow rate of oxygen is less than the lower limit of the preset flow rate threshold range, it indicates that the content of condensed water in the hollow tubular fiber membrane 12 in the oxygen enrichment component 1 is large, and the condensed water has affected the separation of oxygen in the air. At this time, the first evacuation process is required for the oxygen enrichment component 1. Among them, in this step, during the first evacuation process of the oxygen enrichment component 1, the first evacuation process of the oxygen enrichment component 1 can be performed for a third preset time T3. The third preset time T3 and the first preset time T1 can be the same, or the third preset time T3 and the first preset time T1 are different.

[0076] In one example, the third preset time T3 can be flexibly set according to the specific structure, specification size or arrangement mode of the hollow tubular fiber membrane 12 of the oxygen enrichment component 1. For example, the third preset time T3 can be 10 s or 20 s, etc., or the third preset time T3 can also be other values, which are not specifically limited here.

[0077] In step S500, when the indoor oxygen concentration reaches the preset concentration range, the oxygen generation mode can be stopped. The lower limit of the preset concentration range can include but is not limited to 26%, and the upper limit of the preset threshold range can include but is not limited to 30%. After the oxygen generation mode is stopped, the second evacuation process of the oxygen enrichment component 1 is performed for a second preset time T2. It should be noted that the second preset time T2 can be flexibly set according to the specific structure, specification size or arrangement mode of the hollow tubular fiber membrane 12 of the oxygen enrichment component 1. For example, the second preset time T2 can be 15 s or 25 s, etc., or the second preset time T2 can also be other values, which are not specifically limited here.

[0078] Among them, in one example, the second evacuation process can include: controlling the gas treatment unit 4 to start, adjusting the opening of the pressure regulating member 2 to the maximum, and operating for the second preset time T2 to drain all the condensed water in the oxygen enrichment component 1 to the outside, effectively preventing the oxygen generation mode of the oxygen enrichment component 1 from being affected by the condensed water in the oxygen enrichment component 1 during the next start-up, and at the same time, improving the service life of the oxygen enrichment component 1.

[0079] In this embodiment, first, a first evacuation process is performed on the oxygen-enriched component 1 to drain the condensed water in the oxygen-enriched component 1 during the shutdown period to the outside through the second outlet 113, reducing the influence of the condensed water on oxygen production in the oxygen production mode of the oxygen-enriched component 1; then, the oxygen-enriched component 1 is controlled to operate in the oxygen production mode, so that the oxygen in the air passing through the oxygen-enriched component 1 is separated and the oxygen is guided into the room; at the same time, during the oxygen production stage, according to the relationship between the oxygen flow rate and the preset flow rate threshold range, the first evacuation process is selectively performed on the oxygen-enriched component 1; finally, after the oxygen production mode ends, a second evacuation process is performed on the oxygen-enriched component 1. By implementing the above steps, while effectively removing the condensed water in the oxygen-enriched component 1, the indoor oxygen concentration can be quickly adjusted, thereby eliminating the influence of the condensed water on oxygen concentration adjustment, effectively reducing the air-conditioning energy consumption, and improving the experience of the air conditioner.

[0080] Referring to Figure 4 As shown, in order to reduce the influence of the possible condensed water in the oxygen-enriched component 1 on oxygen production when the air conditioner is turned on, after the air conditioner is turned on, a first evacuation process is first performed on the oxygen-enriched component 1. Among them, the first evacuation process may include: controlling the gas treatment unit 4 to start and adjusting the opening of the pressure regulating member 2 to the maximum, that is, adjusting the opening of the back pressure valve to the maximum, so that the hollow tubular fiber membrane 12 meets the preset conditions, thereby draining the condensed water in the oxygen-enriched component 1 during the shutdown stage to the outside, reducing the influence of the condensed water on the oxygen production mode, and ensuring and increasing the service life of the oxygen-enriched component 1.

[0081] Referring to Figure 5 As shown, in some embodiments, the preset condition is: along the air flow direction in the hollow tubular fiber membrane 12, the upstream pressure and the downstream pressure of the condensed water in the hollow tubular fiber membrane satisfy the following formula: F 上 > F 下 + F0, where F 上 is the product of the input pressure P in of the air flow in the hollow tubular fiber membrane 12 and the cross-sectional area S of the hollow tubular fiber membrane 12; F 下 is the product of the output pressure P out of the air flow in the hollow tubular fiber membrane 12 and the cross-sectional area S of the hollow tubular fiber membrane 12; F0 is the resistance of the membrane filaments in the hollow tubular fiber membrane group 12 to the condensed water along the air flow direction. That is: P in * S > P out * S + F0.

[0082] That is to say, the pressure of the condensed water upstream of the hollow tubular fiber membrane 12 is greater than the sum of the pressure of the condensed water downstream of the hollow tubular fiber membrane 12 and the resistance of the condensed water moving in the hollow tubular fiber membrane 12.

[0083] After the first evacuation process runs for the first preset time T1, control the oxygen enrichment component 1 to operate in the oxygen generation mode. In the oxygen generation mode, control the opening degree of the pressure regulating component 2 within a preset range, so that oxygen and nitrogen in the air passing through the oxygen enrichment component 1 are separated. The oxygen is transported to the indoor through the first outlet 112, facilitating the indoor personnel to regulate the oxygen concentration in the room, while the nitrogen is drained to the outdoor through the second outlet 113.

[0084] Among them, during the process of controlling the opening degree of the pressure regulating component 2 within a preset range, the opening degree of the pressure regulating valve 2 can be controlled within a preset range through manual or automatic control methods, so as to maintain a preset pressure range within the oxygen enrichment component 1. Among them, the preset range of the pressure regulating component 2 can be flexibly controlled according to the required pressure within the oxygen enrichment component 1, and the preset pressure range within the oxygen enrichment component 1 is 0.1 Mpa to 0.8 Mpa. Specifically, a pressure gauge (not shown in the figure) can be provided on the housing 11, and the pressure within the housing 11 is immediately displayed through the pressure gauge, and then the opening degree of the pressure regulating component 2 is adjusted and controlled.

[0085] It should be noted that within the preset pressure range within the oxygen enrichment component 1, as the internal pressure increases, the oxygen content flowing out from the first outlet 112 can be adjusted between 23% and 43%.

[0086] In some embodiments, define the oxygen flow rate in the first outlet 112 as XL / min. The preset flow rate threshold range is AL / min to BL / min, where AL / min is the lower limit of the preset flow rate threshold range and BL / min is the upper limit of the preset flow rate threshold range. In one example, AL / min is preferably set to 1 L / min.

[0087] In the oxygen generation mode, as oxygen continuously generates in the hollow tubular fiber membrane 12, the condensate water within the housing 11 continuously increases, and the condensate water gradually fills into some structures within the hollow tubular fiber membrane 12, causing the oxygen concentration transported from the first outlet 112 to continuously decrease until the oxygen flow rate XL / min < ALmin.

[0088] When the oxygen flow rate flowing out from the first outlet 112 is less than 1 L / min, that is, the oxygen flow rate is less than the lower limit of the preset flow rate threshold range, at this time, perform the first evacuation process on the oxygen enrichment component 1 for the third preset time T3 to completely remove the condensate water in the oxygen enrichment component 1, eliminate the influence of the condensate water on the oxygen concentration regulation, and thus improve the experience of the air conditioner.

[0089] Refer to Figure 6As shown, in some embodiments, before performing the first evacuation process on the oxygen-enriched component 1 to stress the condensed water in the oxygen-enriched component 1 to the outside through the second outlet 113 during the shutdown period, the air conditioner condensed water treatment method of the present invention further includes the following steps:

[0090] Step S10: Primarily filter the air through a primary filtration unit.

[0091] Step S20: Compress the filtered air through a gas treatment unit.

[0092] Step S30: The air after the compression outlet is input into the oxygen-enriched component.

[0093] In step S10, the air can be preliminarily filtered through the primary filtration unit 3 in the upstream pipeline of the air inlet 111. Among them, the primary filtration unit 3 can include, but is not limited to, a primary air filter element, etc. For the convenience of monitoring the temperature and humidity of the air entering the oxygen-enriched 1, a temperature and humidity sensor can also be provided on the upstream pipeline of the primary filtration unit 3.

[0094] In step S20, the filtered air can be compressed through the gas treatment unit 4 provided on the pipeline between the primary filtration unit 3 and the air inlet 111. Among them, the gas treatment unit 4 can include, but is not limited to, a compressor or a compression pump, etc.

[0095] In step S30, the temperature of the compressed air will increase to form hot air. At the same time, the hot air is transported into the oxygen-enriched component 1 through the air inlet 111 by using a compressor or a compression pump.

[0096] In this embodiment, the humidity of the air is first monitored and filtered to reduce the impurities in the air and prevent the impurities in the air from clogging the membrane filaments in the hollow tubular fiber membrane 12. Then, the filtered air is compressed to form hot air in a compressed state, which is convenient for subsequent condensation in the housing 11. While removing the moisture in the air, the influence of the condensed water on the oxygen concentration adjustment is reduced, so as to effectively ensure and extend the service life of the air conditioner.

[0097] As Figure 7 shown, an exemplary embodiment of the present invention further provides an air conditioner 10. Among them, the air conditioner 10 includes a controller 101, and the controller 101 includes a memory 1011 and a processor 1012 connected to the memory 1011. The memory 1011 is used to store a program, and the program is at least used to implement the air conditioner condensed water treatment method in the above embodiment.

[0098] The processor 1012 is used to call and execute the program stored in the memory 1011.

[0099] In the above solution, through the cooperation of the pressure regulating member 2 and the oxygen-enriched component 1, while effectively removing the condensate water in the condensation chamber, the oxygen concentration content of the indoor air is adjusted, thereby eliminating the influence of the condensate water on the adjustment of the oxygen concentration and improving the experience of the air conditioner.
