[0048] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] Embodiments of the present invention are described in detail below. 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 be used to explain the present invention, but should not be construed as limiting the present invention.

[0050] like Figure 1 and Figure 2 As shown, an exemplary embodiment of the present invention provides an air conditioner, wherein the air conditioner of the present invention comprises an oxygen enrichment component 1 and a pressure regulating member 2, wherein the oxygen enrichment component 1 comprises a shell 11, a condensation chamber 12 and a hollow tubular fiber membrane group 13 arranged in the shell 11.

[0051] The shell 11 is a hollow structure, and the shape of the shell 11 may include but is not limited to a cuboid, a cylinder or an ellipsoid. The shell 11 is provided with an air inlet 111 for air to enter, and the shell 11 is provided with at least a first outlet 112, a second outlet 113 and a third outlet 114.

[0052] Among them, a primary filter unit 3 and a gas processing unit 4 are arranged in the upstream pipeline of the air inlet 111. The primary filter unit 3 is used to preliminarily filter the air entering the condensation chamber 12. In some embodiments, the primary filter unit 3 may include but is not limited to a primary air filter element, and a humidity sensor 5 may also be arranged in the upstream pipeline of the primary air filter element to monitor the humidity in the air entering the housing 11. The gas processing unit 4 is arranged on the pipeline between the primary filter unit 3 and the air inlet 111, and the gas processing unit 4 is used to compress the filtered air, and the gas processing unit 4 may include but is not limited to a compressor or a compression pump.

[0053] The first outlet 112 is arranged below the condensation chamber 12 for the condensed water to flow out; the second outlet 113 is connected to the indoor room and is arranged below the hollow tubular fiber membrane group 13 for guiding oxygen to the indoor room; the third outlet 114 is connected to the outdoor room and is arranged on the side of the hollow tubular fiber membrane group 13 for guiding nitrogen to the outdoor room.

[0054] Along the flow direction of the air, the condensation chamber 12 is arranged upstream of the shell 11, and the condensation chamber 12 is connected to the air inlet 111. When the compressed hot air enters the condensation chamber 12, since the temperature in the condensation chamber 12 is lower than the temperature of the hot air, the moisture in the air is condensed and condensed water is precipitated, and the condensed water can be discharged to the outside of the oxygen enrichment component 1 through the first outlet 112. It should be noted that a control valve 6 is provided in the downstream pipeline of the first outlet 112, and the control valve 6 can be controlled manually or automatically, wherein the automatic control process of the control valve 6 can be controlled by the control system in the air conditioner.

[0055] The hollow tubular fiber membrane group 13 is located downstream of the condensation chamber 12. Along the flow direction of the air, both ends of the hollow tubular fiber membrane group 13 are fixedly connected to the inner wall of the shell 11 through a fixing ring or a fixing sheet. Among them, one end of the hollow tubular fiber membrane group 13 facing the air inlet 111 is connected to the condensation chamber and / or extends into the condensation chamber 12 by a predetermined distance, so that the air passing through the condensation chamber 12 enters the hollow tubular fiber membrane group 13.

[0056] In some embodiments, the hollow tubular fiber membrane group 13 includes a plurality of hollow tubular fiber membranes 131 arranged in an array. The plurality of hollow tubular fiber membranes 131 may be arranged in a rectangular array or in a circular array.

[0057] Wherein, a pressure regulating member 2 is provided in the downstream pipeline of the third outlet 114. The pressure regulating member 2 is used to adjust the pressure in the oxygen-enriched component 1, specifically, the pressure regulating member 2 is used to adjust the pressure in the shell 11. In some examples, the pressure regulating member 2 may include but is not limited to a back pressure valve. Wherein, when the opening of the back pressure valve is adjusted to the maximum, at this time, there is no pressure on the end side of the third outlet 114, and air can enter from the air inlet end of the hollow tubular fiber membrane group 13 and flow out from the other side of the hollow tubular fiber membrane group 13. When the opening of the back pressure valve is less than the maximum opening, the gas flow in the downstream pipeline of the third outlet 114 is reduced, so that the pressure in the shell 11 increases, and the oxygen in the air overflows from the multiple hollow tubular fiber membranes 131, and oxygen-enriched air is formed. The oxygen-enriched air flows out from the second outlet 113 and is transported to the room, thereby increasing the oxygen concentration of the indoor air. The nitrogen in the air directly moves along the extension direction of the hollow tubular fiber membrane 131 until it is discharged from the third outlet 114 and finally guided to the outside after passing through the back pressure valve.

[0058] In order to obtain the flow rate of oxygen-enriched air in the second outlet 113, a flow sensor 7 is provided in the downstream pipeline of the second outlet 113. In some embodiments, an oxygen concentration sensor 8 may be provided in the pipeline downstream of the flow sensor 7, and the oxygen concentration sensor 8 is used to monitor the oxygen concentration in the oxygen-enriched air, so that indoor personnel can monitor and control the indoor oxygen concentration.

[0059] It should be noted that the pipes between the various components in this example are all connecting pipes.

[0060] In the air conditioner of this embodiment, the filtered air is transported to the gas processing unit 4 and compressed into hot air by the gas processing unit 4. Then, the hot air enters the condensation chamber 12. Since the temperature in the condensation chamber 12 is lower than the temperature of the hot air, the moisture in the hot air is precipitated and forms condensed water, wherein the condensed water can be guided to the outside. The condensed air enters the hollow tubular fiber membrane 131. Under the regulating action of the pressure regulating member 2, the oxygen in the air is separated and processed by controlling the pressure in the oxygen-enriched component 1. Finally, nitrogen is transported to the outside through the third outlet 114, and oxygen is transported to the room through the second outlet 113, thereby increasing the oxygen content of the indoor air, realizing the indoor oxygen concentration regulation and the discharge of condensed water, realizing the self-cleaning process of the air conditioner, eliminating the influence of condensed water on the oxygen concentration regulation, and improving the experience of the air conditioner.

[0061] Since the air conditioner of the present invention only needs the cooperation of the hollow tubular fiber membrane 131 and the back pressure valve to realize the process of indoor oxygenation and condensed water discharge, the energy consumption of the air conditioner is effectively reduced. At the same time, the structure for oxygen concentration adjustment and condensed water discharge in the air conditioner is simple and compact, and can be integrated into the air conditioner or other household appliances (such as purifiers or cold fans, etc.), or can be directly installed in the user's room to achieve the same effect.

[0062] It should be noted that the condensed water in the condensation chamber can be discharged to the outside through the first outlet 112, or can also be discharged to the outside through the third outlet 114. The process of discharging the condensed water to the outside through the third outlet 114 is described in the embodiment of the following air conditioning condensed water treatment method.

[0063] like Figure 3 As shown, an exemplary embodiment of the present invention provides an air conditioning condensate water treatment method, the air conditioning condensate water treatment method comprising the following steps:

[0064] Step S100: Control the opening of the pressure regulating member to a preset range to separate oxygen and nitrogen in the air passing through the oxygen enrichment component, wherein oxygen is input into the room through the second outlet and nitrogen is discharged to the outside through the third outlet.

[0065] Step S200: obtaining the flow rate of oxygen in the second outlet.

[0066] Step S300: selectively performing condensed water removal processing on the oxygen enrichment component according to the relationship between the flow rate and a preset flow rate threshold range.

[0067] Reference Figure 3 Combined with Figure 1 and Figure 2 As shown, in step S100, the pressure regulating member 2 may include but is not limited to a back pressure valve. Wherein, when the opening of the back pressure valve is adjusted to the maximum, there is no pressure on the end side of the third outlet 114, and air can enter from the air inlet end of the hollow tubular fiber membrane group 13 and flow out from the other end of the hollow tubular fiber membrane group 13. When the opening of the back pressure valve is less than the maximum opening, at this time, the gas flow in the downstream pipeline of the third outlet 114 is reduced, so that the pressure in the shell 11 increases, and the oxygen in the air overflows from the multiple hollow tubular fiber membranes 131, thereby separating the oxygen and nitrogen in the air. Oxygen flows out from the second outlet 113 and is transported to the room to increase the oxygen concentration of the indoor air. The nitrogen in the air moves directly along the extension direction of the hollow tubular fiber membrane group 13 until it flows out from the third outlet 114, and is finally guided to the outside after passing through the back pressure valve.

[0068] In some embodiments, the opening of the pressure regulating member 2 can be controlled to a preset range so that the preset pressure range is maintained in the oxygen-enriched component 1, thereby separating the oxygen and nitrogen in the air passing through the oxygen-enriched component 1. The preset range of the pressure regulating member 2 can be controlled according to the required pressure in the oxygen-enriched component 1, and the preset pressure range in the oxygen-enriched component 1 is 0.1Mpa to 0.8Mpa. Specifically, a pressure gauge (not shown in the figure) can be provided on the shell 11. The pressure gauge instantly displays the pressure feedback in the shell 11, thereby adjusting and controlling the opening of the pressure regulating member 2. It should be noted that within the preset pressure range in the oxygen-enriched component 1, as the internal pressure increases, the oxygen concentration in the oxygen-enriched component 1 can be adjusted from 23% to 43%.

[0069] In step S200, the flow rate of oxygen in the second outlet 113 can be obtained by the flow sensor 7 provided in the downstream pipeline of the second outlet 113. At the same time, an oxygen concentration sensor 8 can be provided in the downstream pipeline of the flow sensor 7 to monitor the concentration of oxygen in the second outlet by using the oxygen concentration sensor 8, so as to facilitate indoor personnel to monitor and control the oxygen concentration in the indoor air.

[0070] In step S300, after the flow rate of oxygen in the second outlet 113 is obtained, the flow rate of oxygen is compared with the preset flow rate threshold range. When the flow rate of oxygen is within the preset flow rate threshold range or is greater than the upper limit of the preset flow rate threshold range, it indicates that the content of condensed water in the condensation chamber 12 is small, and it is not necessary to perform condensed water removal processing on 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 condensation chamber 12 is large, and the condensation chamber has affected the separation of oxygen in the air. At this time, it is necessary to perform condensed water removal processing on the oxygen enrichment component 1.

[0071] In this embodiment, through the cooperation of the pressure regulating component 2 and the oxygen enrichment component 1, the oxygen concentration content of the indoor air is adjusted while the condensed water in the condensation chamber is effectively removed, thereby eliminating the influence of the condensed water on the regulation of the oxygen concentration and improving the air conditioning experience.

[0072] In some embodiments, the flow rate of oxygen in the second outlet 113 is defined as XL / min. The preset flow rate threshold range is AL / min to BL / min, wherein 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 can be set to 1 L / min.

[0073] As oxygen is continuously produced in the hollow tubular fiber membrane group 13, the amount of condensed water in the condensation chamber 12 continues to increase, and the condensed water gradually fills the condensation chamber 12 and the partial structure of the hollow tubular fiber membrane group 13 facing the air inlet 111, causing the oxygen concentration from the second outlet 113 to continue to decrease until the oxygen flow rate XL / min<ALmin.

[0074] In the step of selectively performing condensed water removal processing on the oxygen enrichment component 1 according to the relationship between the flow rate and the preset flow rate threshold range, when the flow rate is less than the lower limit of the preset flow rate threshold range, that is, XL / min<1L / min, the oxygen enrichment component 1 is firstly subjected to a first processing for a first preset time to remove part of the condensed water in the oxygen enrichment component 1, for example, the condensed water in the condensation chamber 12 of the oxygen enrichment component 1 is firstly removed. The first preset time can be flexibly set according to the structure or capacity of the condensation chamber 12, for example, the first preset time can be 10S or 20S, or the first preset time can also be other values.

[0075] Then, after the first preset time, the oxygen enrichment component 1 is subjected to a second treatment and operated for a second preset time to remove the remaining condensed water in the oxygen enrichment component 1. For example, in the second treatment stage, part of the condensed water stored in the hollow tubular fiber membrane group 13 is removed. The second preset time can be flexibly set according to the structure or arrangement of the hollow tubular fiber membrane group 13, for example, the second preset time can be 20S or 30S, or the second preset time can also be other values.

[0076] In this embodiment, through the first treatment and the second treatment, the condensed water in the oxygen enrichment component 1 is completely removed, the influence of the condensed water on the oxygen concentration condition is eliminated, and the air conditioning experience is improved.

[0077] Reference Figure 4 As shown, in some embodiments, the operation of performing a first treatment for a first preset time on the oxygen enrichment component 1 includes:

[0078] The pressure regulating member 2 (ie, the back pressure valve) is closed or the opening of the pressure regulating member 2 is maintained, and the first outlet 112 is connected, that is, the control valve 6 is opened, so that all the condensed water in the condensation chamber 12 is drained to the outside.

[0079] Among them, after closing the pressure regulating component 2, the gas processing unit 4 is maintained to continue to operate, so that the pressure in the condensation chamber 12 increases. As the hot air continues to flow into the condensation chamber 12, the hot air can carry the condensed water in the condensation chamber 12 and be discharged from the first outlet 112.

[0080] When the opening of the pressure regulating member 2 is maintained, the first outlet 112 is opened, and the hot air flowing into the condensation chamber 12 can also carry the condensed water in the condensation chamber 12 and flow out from the first outlet 112. Different from the method of closing the pressure regulating member 2, the pressure in this method (i.e. maintaining the opening of the pressure regulating member 2) is lower than the pressure in the method of closing the pressure regulating member 2. However, both of the above methods can guide the condensed water in the condensation chamber 12 to the outside, thereby reducing the influence of the condensed water on the oxygen concentration regulation.

[0081] Reference Figure 4 As shown, in some embodiments, the operation of performing the second treatment on the oxygen-enriching component 2 includes:

[0082] The first outlet 112 is cut off, that is, the control valve 6 is closed, and the opening of the pressure regulating member 2 is adjusted to the maximum, so that the preset conditions are met in the hollow tubular fiber membrane group 13 to drain the condensed water in the hollow tubular fiber membrane group 13 from the third outlet 114 to the outside.

[0083] In one example, the preset condition is: along the airflow movement direction in the hollow tubular fiber membrane group 13, the upstream pressure and downstream pressure of the condensed water in the hollow tubular fiber membrane group 13 satisfy the following formula:

[0084] F 上 >F 下 +F 0 , where F 0 It is the resistance of the membrane fibers in the hollow tubular fiber membrane group 13 to the condensed water along the airflow moving direction.

[0085] Among them, refer to Figure 5 As shown, in some embodiments, the hollow tubular fiber membrane group 13 includes a plurality of hollow tubular fiber membranes 131 arranged in an array. Therefore, the upstream pressure F of the condensed water in the hollow tubular fiber membrane group 13 is 上 is the input pressure P of the airflow in the hollow tubular fiber membrane 131 in The product of the cross-sectional area S of the hollow tubular fiber membrane 131. The downstream pressure F of the condensed water in the hollow tubular fiber membrane group 13 下 is the output pressure P of the airflow in the hollow tubular fiber membrane 131 out The product of P and the cross-sectional area S of the hollow tubular fiber membrane 131. That is: in *S>P out *S+F0.

[0086] That is to say, the pressure of the condensed water upstream of the hollow tubular fiber membrane group 13 is greater than the pressure of the condensed water downstream of the hollow tubular fiber membrane group 13 and the resistance of the condensed water to move in the hollow tubular fiber membrane 131. At this time, the condensation chamber 12 is in an empty state, and the first outlet 112 is in a closed state after closing the control valve 6. At this time, the gas processing unit 4 is maintained to continue to operate, and the opening of the pressure regulating member 2 is adjusted to the maximum, so that the pressure in the hollow tubular fiber membrane group 13 is rapidly reduced along the gas flow direction. As the hot air is continuously transported into the condensation chamber 13, due to the effect of pressure, the condensed water in the hollow tubular fiber membrane 131 moves along the direction of gas flow, and is finally discharged from the third outlet 114, and is discharged to the outside through the back pressure valve.

[0087] When all the condensed water in the condensation chamber 12 and the hollow tubular fiber membrane group 13 is drained, the oxygen enrichment component 1 resumes the oxygen production process, thereby increasing the oxygen concentration in the indoor air. During the oxygen production process, until the oxygen flow rate XL / min is less than 1L / min, the air conditioner control system controls and enters the condensation chamber removal treatment stage again.

[0088] In this embodiment, the pressure in the shell 11 is adjusted by the pressure regulating member 2 so that the condensed water in the hollow tubular fiber membrane group 13 is discharged to the outside, eliminating the influence of the condensed water on the hollow tubular fiber membrane 131 and improving the oxygen production efficiency of the hollow tubular fiber membrane 131.

[0089] Reference Figure 6As shown, in some embodiments, before step S100, the air conditioning condensate water treatment method of the present invention further includes the following steps:

[0090] Step S10: performing primary filtration on the air through a primary filtration unit.

[0091] Step S20: compressing the filtered air through the gas processing unit.

[0092] Step S30: inputting the compressed air into the oxygen enrichment component.

[0093] In step S10, a primary air filter element (i.e., a primary filter unit 3) may be provided in the upstream pipeline of the air inlet 111 to preliminarily filter the air. In order to facilitate monitoring of the humidity of the air entering the oxygen enrichment component 1, a humidity sensor 5 may also be provided in the upstream pipeline of the primary filter unit 3.

[0094] In step S20, a gas processing unit 4 may be provided on the pipeline between the primary filter unit 3 and the air inlet 111. The gas processing unit 4 is used to compress the filtered air. The gas processing unit 4 may include but is not limited to a compressor or a compression pump.

[0095] In step S30 , the temperature of the compressed air will increase and form hot air. At the same time, the hot air can be transported to the condensation chamber 12 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 impurities in the air and prevent the impurities in the air from clogging the membrane fibers in the hollow tubular fiber membrane 131. The filtered air is then compressed to form compressed hot air to facilitate the subsequent condensation process in the condensation chamber 12. While removing moisture from the air, the effect of condensed water on the oxygen concentration adjustment is reduced, so as to effectively ensure and increase the service life of the air conditioner.

[0097] like Figure 7 As shown, an exemplary embodiment of the present invention provides an air conditioner 10. 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, which is at least used to implement the air conditioning condensed water treatment method in the above embodiment.
