[0060] In the field of air-conditioning related technology, for example, oxygen-generating air conditioners play a huge role in high-altitude areas where oxygen is relatively thin. During the oxygen production process, the oxygen generator of the oxygen-generating air conditioner has a problem that the molecular sieve will decay the oxygen concentration as the air temperature rises and falls, resulting in low oxygen production efficiency of the oxygen-generating air conditioner.

[0061] Based on this, the following embodiments are proposed.

[0062] Embodiment 1:

[0063] like Figure 1 As shown, this embodiment provides an oxygen concentrator, comprising:

[0064] A nitrogen-oxygen separator, wherein an output end of the nitrogen-oxygen separator is connected with an oxygen pipeline and a nitrogen pipeline;

[0065] The air compressor 3 and the gas storage tank 4, and the nitrogen and oxygen separator are connected between the air compressor 3 and the gas storage tank 4;

[0066] Between the output end of the air compressor 3 and the input end of the nitrogen-oxygen separator, there is a first air flow path 301 for allowing air to flow to the nitrogen-oxygen separator via the heat exchanger 6 and a second air flow path 302 for allowing air to flow to the nitrogen-oxygen separator without passing through the heat exchanger 6;

[0067] The oxygen pipeline is connected to the input end of the gas storage tank 4, and the nitrogen pipeline is used to discharge the nitrogen to the outside of the oxygen generator.

[0068] In this embodiment, the air compressor 3 is operated to transport the ambient air to the nitrogen-oxygen separator. The nitrogen-oxygen separator is composed of a single molecular sieve or a plurality of molecular sieves. The principle of molecular sieves for separating nitrogen and oxygen in the air is a technical content well known to those skilled in the art, and will not be repeated here. The air enters the nitrogen-oxygen separator from the input end of the nitrogen-oxygen separator through the first air flow path 301 or the second air flow path 302, and is separated into nitrogen and oxygen. The oxygen part enters the gas storage tank 4 through the oxygen pipeline, and the nitrogen part is discharged separately.

[0069] like Figure 2 As shown, taking the nitrogen oxygen separator as a molecular sieve as an example for explanation, under different air temperatures, its oxygen production concentration value, it can be seen that keeping the air temperature between 0°C and 60°C can keep the nitrogen oxygen separator with a high working efficiency. By designing the first air flow path 301 and the second air flow path 302, the oxygen generator can selectively dissipate heat or keep warm the air before entering the nitrogen oxygen separator according to the heat dissipation needs of the external ambient air, so that the temperature value of the air entering the nitrogen oxygen separator reaches a temperature range suitable for the operation of the nitrogen oxygen separator, that is, between 0°C and 60°C, avoiding the problem of oxygen production concentration attenuation in the nitrogen oxygen separator as the air temperature changes, thereby effectively improving the oxygen production efficiency of the nitrogen oxygen separator, and further improving the oxygen production efficiency and oxygen production stability of the oxygen generator.

[0070] Regarding the heat exchanger 6, a heat dissipation pipeline can be provided for air circulation. A heat dissipation component is provided on the heat dissipation pipeline to exchange heat between the air in the heat dissipation pipeline and the heat dissipation component, thereby reducing the air temperature.

[0071] Optionally, in an implementation of this embodiment, as Figure 1 As shown,

[0072] The first air flow path 301 is connected in series with a first valve 5 and a heat exchanger 6 in the air flow direction;

[0073] The second air flow path 302 is connected in series with a second valve 7;

[0074] The inlet end of the second valve 7 is located upstream of the first valve 5 , and the outlet end of the second valve 7 is located downstream of the heat exchanger 6 .

[0075] In this embodiment, according to the heat dissipation requirement of the air, that is, when the air temperature is high, the controller controls the first valve 5 to open and the second valve 7 to close, so that the air passes through the heat exchanger 6. After the heat is dissipated by the heat exchanger 6, the air temperature is lowered, which is suitable for oxygen production by the nitrogen-oxygen separator.

[0076] According to the need for air insulation, that is, when the air temperature is low, the controller controls the first valve 5 to close and the second valve 7 to open, so that the air does not pass through the heat exchanger 6. The air that does not pass through the heat exchanger 6 is compressed by the air machine 3 and enters the nitrogen and oxygen separator. The characteristic of the air compressor 3 itself to compress the air to increase its temperature is utilized, so that the air with a lower temperature can be compressed and then heated to a suitable temperature to enter the nitrogen and oxygen separator, which is suitable for oxygen production by the nitrogen and oxygen separator.

[0077] By designing the first valve 5 and the heat exchanger 6 in series on the first air flow path 301 and the second valve 7 in series on the second air flow path 302, the temperature of the air entering the nitrogen oxygen separator can reach a temperature range suitable for the operation of the nitrogen oxygen separator, that is, between 0°C and 60°C, thereby avoiding the problem of oxygen concentration decay in the nitrogen oxygen separator as the air temperature changes, thereby effectively improving the oxygen production efficiency of the nitrogen oxygen separator, and further improving the oxygen production efficiency and oxygen production stability of the oxygen generator.

[0078] Optionally, in an implementation of this embodiment, as Figure 1 As shown,

[0079] The nitrogen oxygen separator comprises a first molecular sieve 1 and a second molecular sieve 2, wherein the output end of the first molecular sieve 1 is connected to a first oxygen pipeline 101 and a first nitrogen pipeline 102, and the output end of the second molecular sieve 2 is connected to a second oxygen pipeline 201 and a second nitrogen pipeline 202;

[0080] The first oxygen pipeline 101 and the second oxygen pipeline 201 are both connected to the input end of the gas tank 4; the first air flow path 301 includes a first output pipeline 3011 and a second output pipeline 3012, the first output pipeline 3011 is connected to the input end of the first molecular sieve 1, and the second output pipeline 3012 is connected to the input end of the second molecular sieve 2.

[0081] In this embodiment, the nitrogen oxygen separator includes at least two molecular sieves, namely a first molecular sieve 1 and a second molecular sieve 2. The air compressor 3 works to provide air for the two molecular sieves. The two molecular sieves are connected in parallel between the air compressor 3 and the gas storage tank 4, so that air can enter the first molecular sieve 1 and the second molecular sieve 2. Therefore, the first molecular sieve 1 and the second molecular sieve 2 can alternately produce oxygen. The two molecular sieves alternately produce oxygen, so that when one of the molecular sieves outputs oxygen, the other molecular sieve discharges nitrogen. The two molecular sieves alternately output oxygen and discharge nitrogen. Compared with the intermittent oxygen output of a single molecular sieve, the setting of the two molecular sieves enables the oxygen generator to continuously output oxygen.

[0082] Optionally, in an implementation of this embodiment, as Figure 1 As shown,

[0083] The oxygen generator further includes: a nitrogen discharge part 13;

[0084] The first nitrogen pipeline 102 and the second nitrogen pipeline 202 are both connected to the nitrogen discharge part 13;

[0085] The first nitrogen pipeline 102 is provided with a third valve 8, and the third valve 8 is used to control whether the first nitrogen pipeline 102 discharges nitrogen;

[0086] The second nitrogen pipeline 202 is provided with a fourth valve 9, and the fourth valve 9 is used to control whether the second nitrogen pipeline 202 discharges nitrogen.

[0087] The first output pipeline 3011 is provided with a fifth valve 10, and the fifth valve 10 is used to control whether the first output pipeline 3011 inputs air to the first molecular sieve 1;

[0088] The second output pipeline 3012 is provided with a sixth valve 11 , and the sixth valve 11 is used to control whether the second output pipeline 3012 inputs air to the first molecular sieve 1 .

[0089] The first oxygen pipeline 101 is provided with a seventh valve 14, and the seventh valve 14 is used to control whether the first oxygen pipeline 101 inputs oxygen to the gas storage tank 4;

[0090] The second oxygen pipeline 201 is provided with an eighth valve 15 , and the eighth valve 15 is used to control whether the second oxygen pipeline 201 inputs oxygen to the gas storage tank 4 .

[0091] In this embodiment, during the alternating oxygen production process of the two molecular sieves, the third valve 8, the fourth valve 9, the fifth valve 10, the sixth valve 11, the seventh valve 14 and the eighth valve 15 cooperate with each other. The working process of the two molecular sieves is described below by example.

[0092] First, the third valve 8, the seventh valve 14, and the sixth valve 11 are closed, and the fifth valve 10 is opened to allow air to enter the first molecular sieve 1. After a certain time or a certain amount of air is introduced, the fifth valve 10 is closed and the sixth valve 11 is opened. After the fifth valve 10 is closed, a closed space is formed in the first molecular sieve 1 to perform nitrogen and oxygen separation work for a certain period of time.

[0093] At the same time or after closing the fifth valve 10, the sixth valve 11 is opened, and the eighth valve 15 and the fourth valve 9 are closed at the same time, so that air enters the second molecular sieve 2. After a certain amount of air is introduced, the sixth valve 11 is closed and the fifth valve 10 is opened. In this way, the first molecular sieve 1 and the second molecular sieve 2 are alternately oxygenated to improve efficiency.

[0094] The first molecular sieve 1 is kept closed for a period of time to separate nitrogen and oxygen, and then the seventh valve 14 is opened to output oxygen to the gas storage tank 4 through the first oxygen pipeline 101, and the third valve 8 is opened to discharge nitrogen through the first nitrogen pipeline 102. The second molecular sieve 2 is similar, and will not be described in detail here.

[0095] Optionally, in an implementation of this embodiment, as Figure 1 As shown,

[0096] A filter 12 is provided at the input end of the air compressor 3 , and the filter 12 is used to filter the air entering the air compressor 3 .

[0097] In this embodiment, the filter 12 is used to filter the air entering the air compressor 3 to remove impurities in the air to prevent the impurities from affecting the nitrogen oxide separator.

[0098] Embodiment 2

[0099] like Figure 3-5 As shown, this embodiment provides an oxygen production control method, which is applied to the oxygen generator in the first embodiment; the oxygen production control method includes:

[0100] Obtaining a target temperature, the target temperature includes the outdoor ambient temperature outside the oxygen concentrator and / or the exhaust temperature of the air compressor 3;

[0101] According to the temperature range to which the target temperature belongs, the first air flow path is controlled to be open or the second air flow path is controlled to be open.

[0102] Specifically, Figure 4 As shown, the target temperature is the outdoor ambient temperature or the exhaust temperature of the air compressor 3;

[0103] Controlling the first air flow path to be open or the second air flow path to be open according to the temperature interval to which the target temperature belongs, including:

[0104] If the target temperature belongs to the preset low temperature range, the first air flow path is controlled to be closed and the second air flow path is controlled to be opened;

[0105] If the target temperature belongs to the preset high temperature range, the first air flow path is controlled to be open, and the second air flow path is controlled to be closed.

[0106] In this embodiment, the target temperature is taken as an example of outdoor ambient temperature. When the outdoor ambient temperature belongs to the preset low temperature range, indicating that the current outdoor ambient temperature is in a state where heat preservation is required, the first air flow path is controlled to be closed, and the second air flow path is controlled to be connected, so that the air does not pass through the heat exchanger 6, and no heat dissipation treatment is performed. The air is compressed by the air machine 3 and enters the nitrogen-oxygen separator. The characteristic of the air compressor 3 itself compressing the air to increase its temperature is used, so that the air with a lower temperature can be compressed and heated to a suitable temperature to enter the nitrogen-oxygen separator, which is suitable for the nitrogen-oxygen separator to produce oxygen. When the outdoor ambient temperature belongs to the preset high temperature range, indicating that the current outdoor ambient temperature is in a state where heat dissipation is required, the first air flow path is controlled to be connected, and the second air flow path is controlled to be closed, so that the air passes through the heat exchanger 6 for heat dissipation treatment. After the heat is dissipated, the temperature of the air is reduced, which is suitable for the nitrogen-oxygen separator to produce oxygen.

[0107] Taking the exhaust temperature of the air compressor 3 as an example, when the exhaust temperature of the air compressor 3 belongs to the preset low temperature range, which is less than 50°C, it indicates that the exhaust temperature of the current air compressor 3 is normal, and the air is compressed by the air compressor 3, and the temperature rise is relatively small, then the first air flow path is controlled to be closed, and the second air flow path is controlled to be connected, so that the air does not pass through the heat exchanger 6, and no heat dissipation treatment is performed, and the air with a lower temperature is compressed and heated to a suitable temperature to enter the nitrogen oxygen separator, which is suitable for the nitrogen oxygen separator to produce oxygen. When the exhaust temperature of the air compressor 3 belongs to the preset high temperature range, which is greater than 60°C, it indicates that the exhaust temperature of the current air compressor 3 is high, and the air is compressed by the air compressor 3, and the temperature rise is relatively large, then the first air flow path is controlled to be closed, and the second air flow path is controlled to be closed, so that the air passes through the heat exchanger 6, and heat dissipation treatment is performed. After the heat is dissipated, the temperature of the air is reduced, which is suitable for the nitrogen oxygen separator to produce oxygen.

[0108] like Figure 5 As shown, specifically, the target temperature is the outdoor ambient temperature and the exhaust temperature of the air compressor 3;

[0109] Controlling the first air flow path to be open or the second air flow path to be open according to the temperature interval to which the target temperature belongs, including:

[0110] Get the outdoor ambient temperature;

[0111] Determine whether the outdoor ambient temperature is within a preset temperature range;

[0112] If the outdoor ambient temperature is within the preset temperature range, the exhaust temperature of the air compressor 3 is obtained;

[0113] Controlling the first air flow path to be open or the second air flow path to be open according to the temperature range to which the exhaust temperature of the air compressor 3 belongs;

[0114] If the outdoor ambient temperature is outside the preset temperature range, the first air flow path is controlled to be open or the second air flow path is controlled to be open according to the temperature interval to which the outdoor ambient temperature belongs.

[0115] Controlling the first air flow path to be open or the second air flow path to be open according to the temperature interval to which the exhaust temperature of the air compressor 3 belongs includes:

[0116] If the exhaust temperature of the air compressor 3 belongs to the first preset low temperature range, the first air flow path is controlled to be closed, and the second air flow path is controlled to be open;

[0117] If the exhaust temperature of the air compressor 3 belongs to the first preset high temperature range, the first air flow path is controlled to be open, and the second air flow path is controlled to be closed.

[0118] In this embodiment, by obtaining the outdoor ambient temperature, it is determined whether the outdoor ambient temperature is within the preset temperature range. If the outdoor ambient temperature is within the preset temperature range, it indicates that when the outdoor ambient temperature is within the temperature range in which the oxygen generator can achieve efficient oxygen production, in this state, the exhaust temperature of the air compressor 3 is further obtained, and the first valve 5 is controlled to be opened and the second valve 7 is controlled to be closed according to the exhaust temperature value of the air compressor 3, so that the air passes through the heat exchanger 6, or the first valve 5 is controlled to be closed and the second valve 7 is controlled to be opened so that the air does not pass through the heat exchanger 6. If the exhaust temperature of the air compressor 3 belongs to the first preset high temperature range, the exhaust temperature of the air compressor 3 is relatively high, indicating that the air compressor 3 will heat up the air in this state. The air jumps out of the preset temperature range. Therefore, when the exhaust temperature of the air compressor 3 is high, the first valve 5 is controlled to be opened and the second valve 7 is closed, so that the air passes through the heat exchanger 6, and the air is heat-dissipated before entering the nitrogen and oxygen separator, so that the air entering the nitrogen and oxygen separator is within the preset temperature range of 0°C to 60°C. If the exhaust temperature of the air compressor 3 belongs to the first preset low temperature interval, when the exhaust temperature of the air compressor 3 is low, it indicates that the air compressor 3 will not heat the air in this state, and the air can remain within the preset temperature range when entering the nitrogen and oxygen separator. Therefore, when the exhaust temperature of the air compressor 3 is low, the first valve 5 is controlled to be closed and the second valve 7 is opened, so that the air does not pass through the heat exchanger 6.

[0119] According to the exhaust temperature of the air compressor 3, the temperature of the air entering the nitrogen-oxygen separator in the oxygen generator is further controlled, thereby further improving the oxygen production efficiency of the nitrogen-oxygen separator.

[0120] If the outdoor ambient temperature is outside the preset temperature range, the first valve 5 is directly controlled to be opened and the second valve 7 is closed according to the outdoor ambient temperature, so that the air passes through the heat exchanger 6, or the first valve 5 is controlled to be closed and the second valve 7 is opened so that the air does not pass through the heat exchanger 6. There is no need to go through the steps of obtaining and comparing the exhaust temperature of the air compressor 3.

[0121] That is, if the outdoor ambient temperature is lower than the minimum value in the preset temperature range, indicating that the current outdoor ambient temperature is in a state that requires insulation, the first air flow path is controlled to be closed and the second air flow path is controlled to be open, so that the air does not pass through the heat exchanger 6 and does not undergo heat dissipation treatment. The air is compressed by the air machine 3 and enters the nitrogen and oxygen separator. The characteristic of the air compressor 3 itself to compress the air and raise its temperature is utilized, so that the air with a lower temperature can be compressed and then heated to a suitable temperature to enter the nitrogen and oxygen separator, which is suitable for oxygen production by the nitrogen and oxygen separator.

[0122] If the outdoor ambient temperature is higher than the maximum value in the preset temperature range, indicating that the current outdoor ambient temperature is in a state where heat dissipation is required, the first air flow path is controlled to be opened and the second air flow path is controlled to be closed, so that the air passes through the heat exchanger 6 for heat dissipation treatment. After the heat is dissipated, the temperature of the air is reduced, which is suitable for oxygen production in the nitrogen oxygen separator.

[0123] Specifically, controlling the first air flow path to be closed and controlling the second air flow path to be open includes:

[0124] Control the first valve 5 to close and the second valve 7 to open so that the air does not pass through the heat exchanger 6;

[0125] Controlling the first air flow path to be turned on and controlling the second air flow path to be turned off includes:

[0126] The first valve 5 is controlled to be open and the second valve 7 is controlled to be closed, so that the air passes through the heat exchanger 6 .

[0127] Embodiment 3

[0128] like Figure 3-5 As shown, this embodiment provides an electronic device,

[0129] a memory for storing one or more computer executable instructions;

[0130] The processor is used to call and execute the computer executable instructions in the memory, so as to implement the oxygen production control method in the second embodiment.

[0131] In this embodiment, the electronic device obtains the target temperature, which includes the outdoor ambient temperature outside the oxygen generator and / or the exhaust temperature of the air compressor 3; and controls the first air flow path to be turned on or the second air flow path to be turned on according to the temperature range to which the target temperature belongs.

[0132] For example, the outdoor ambient temperature is obtained to determine whether the outdoor ambient temperature is within a preset temperature range. If the outdoor ambient temperature is within the preset temperature range, it indicates that the current external ambient temperature is within the temperature range in which the oxygen generator can achieve efficient oxygen production. In this state, the exhaust temperature of the air compressor 3 is further obtained, and the first valve 5 is controlled to be opened and the second valve 7 is controlled to be closed according to the exhaust temperature value of the air compressor 3, so that the air passes through the heat exchanger 6, or the first valve 5 is controlled to be closed and the second valve 7 is controlled to be opened so that the air does not pass through the heat exchanger 6. That is, when the exhaust temperature of the air compressor 3 is high, it indicates that the air compressor 3 will cause the air to rise in this state. temperature, so that the air jumps out of the preset temperature range. Therefore, when the exhaust temperature of the air compressor 3 is high, the first valve 5 is controlled to be opened and the second valve 7 is closed, so that the air passes through the heat exchanger 6, and the air is heat-dissipated before entering the nitrogen and oxygen separator, so that the air entering the nitrogen and oxygen separator is within the preset temperature range of 0°C to 60°C. When the exhaust temperature of the air compressor 3 is low, it indicates that the air compressor 3 will not heat the air in this state, and the air can be kept within the preset temperature range when entering the nitrogen and oxygen separator. Therefore, when the exhaust temperature of the air compressor 3 is low, the first valve 5 is controlled to be closed and the second valve 7 is controlled to be opened, so that the air does not pass through the heat exchanger 6. According to the exhaust temperature of the air compressor 3, the temperature of the air entering the nitrogen and oxygen separator in the oxygen generator is further controlled, thereby further improving the oxygen production efficiency of the nitrogen and oxygen separator.

[0133] Embodiment 4

[0134] This embodiment provides an oxygen-generating air conditioner, such as Figure 1 , 2 As shown, including:

[0135] The oxygen generator in the first embodiment is controlled by the oxygen generation control method in the second embodiment, or includes the electronic device in the third embodiment.

[0136] In this embodiment, the oxygen-generating air conditioner works through the air compressor 3 to deliver the ambient air to the nitrogen-oxygen separator. The nitrogen-oxygen separator is composed of a single molecular sieve or a plurality of molecular sieves. The principle of molecular sieves for separating nitrogen and oxygen in the air is a technical content well known to those skilled in the art, and will not be repeated here. The air enters the nitrogen-oxygen separator from the input end of the nitrogen-oxygen separator through the first air flow path 301 or the second air flow path 302, and is separated into nitrogen and oxygen. The oxygen part enters the gas storage tank 4 through the oxygen pipeline, and the nitrogen part is discharged separately.

[0137] like Figure 2As shown, taking the nitrogen oxygen separator as a molecular sieve as an example for explanation, under different air temperatures, its oxygen production concentration value, it can be seen that keeping the air temperature between 0°C and 60°C can keep the nitrogen oxygen separator with a high working efficiency. By designing the first air flow path 301 and the second air flow path 302, the oxygen generator can selectively dissipate heat or keep warm the air before entering the nitrogen oxygen separator according to the heat dissipation needs of the external ambient air, so that the temperature value of the air entering the nitrogen oxygen separator reaches a temperature range suitable for the operation of the nitrogen oxygen separator, that is, between 0°C and 60°C, avoiding the problem of oxygen production concentration attenuation in the nitrogen oxygen separator as the air temperature changes, thereby effectively improving the oxygen production efficiency of the nitrogen oxygen separator, and further improving the oxygen production efficiency and oxygen production stability of the oxygen generator.

[0138] In summary, the ingenious conception of the oxygen generator and the oxygen production control method is:

[0139] First, by designing the first air flow path and the second air flow path, the oxygen generator can selectively dissipate heat or keep warm the air before entering the nitrogen oxygen separator according to the heat dissipation needs of the external ambient air, so that the temperature of the air entering the nitrogen oxygen separator reaches a temperature range suitable for the operation of the nitrogen oxygen separator, avoiding the problem of oxygen concentration decay in the nitrogen oxygen separator as the air temperature changes, thereby effectively improving the oxygen production efficiency of the nitrogen oxygen separator, and further improving the oxygen production efficiency and oxygen production stability of the oxygen generator.

[0140] Second, by obtaining the outdoor ambient temperature, it is determined whether the outdoor ambient temperature is within the preset temperature range. If the outdoor ambient temperature is within the preset temperature range, it indicates that the current external ambient temperature is within the temperature range in which the oxygen generator can achieve efficient oxygen production. In this state, the exhaust temperature of the air compressor is further obtained, and the first valve is controlled to be opened and the second valve is controlled to be closed according to the exhaust temperature value of the air compressor, so that the air passes through the heat exchanger, or the first valve is controlled to be closed and the second valve is controlled to be opened so that the air does not pass through the heat exchanger. That is, when the exhaust temperature of the air compressor is high, it indicates that the air compressor will heat up the air in this state, so that the air jumps out of the preset temperature range. Therefore, when the exhaust temperature of the air compressor is high, the first valve is controlled to be opened and the second valve is controlled to be closed, so that the air passes through the heat exchanger, and the air is heat-dissipated before entering the nitrogen-oxygen separator, so that the air entering the nitrogen-oxygen separator is within the preset temperature range. When the exhaust temperature of the air compressor is low, it indicates that the air compressor will not heat up the air in this state, and the air can remain within the preset temperature range when entering the nitrogen-oxygen separator. Therefore, when the exhaust temperature of the air compressor is low, the first valve is controlled to be closed and the second valve is controlled to be opened so that the air does not pass through the heat exchanger. According to the exhaust temperature of the air compressor, the temperature of the air entering the nitrogen and oxygen separator in the oxygen generator is further controlled, thereby further improving the oxygen production efficiency of the nitrogen and oxygen separator.
