[0002] In air-conditioning related technologies, although traditional air-conditioning systems can adjust the indoor temperature when operating in a relatively closed space, they will cause the indoor oxygen content to decrease. To address this problem, the general solution is to use fresh air air-conditioning to introduce fresh air into the room.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] In air-conditioning related technologies, although traditional air-conditioning systems can adjust the indoor temperature when operating in a relatively closed space, they will cause the indoor oxygen content to decrease. To address this problem, the general solution is to use fresh air air-conditioning to introduce fresh air into the room. However, the fan of the fresh air air-conditioning located indoors needs to run at a higher speed to obtain a good air outlet effect, resulting in greater noise indoors. In addition, if in high altitude areas, when the oxygen content of the outdoor air is low, the fresh air air-conditioning is difficult to meet the demand for increasing the indoor oxygen content.

[0053] Based on this, the following embodiments are proposed.

[0054] Embodiment 1:

[0055] like Figure 1 , 2 As shown, this embodiment provides an air conditioner, including an indoor unit 1 and an outdoor unit 2, and the air conditioner also includes:

[0056] An oxygen concentrator 3, the oxygen concentrator 3 is arranged in the outdoor unit 2;

[0057] The indoor unit 1 is provided with an oxygen inlet 6 and an air outlet 7, and the oxygen inlet 6 is connected to the air outlet 7;

[0058] The oxygen concentrator 3 is provided with an oxygen outlet 8, and the oxygen outlet 8 is connected to the oxygen inlet 6;

[0059] The oxygen generator 3 is provided with a compressor and an oxygen generator;

[0060] The compressor is designed to: output the outdoor air to the oxygen production unit, or output the outdoor air to the indoor unit 1 and discharge it indoors;

[0061] The oxygen production unit is designed to produce oxygen from the air provided by the compressor, and allow the oxygen to enter the oxygen inlet 6 through the oxygen outlet 8 and be discharged into the room through the air outlet 7 .

[0062] Preferably, the indoor unit 1 is further provided with a fresh air inlet 4 and a fresh air outlet 5, and the fresh air inlet 4 and the fresh air outlet 5 are both connected to the air outlet 7;

[0063] The oxygen generator 3 is also provided with a circulating air outlet 9, and the circulating air outlet 9 is connected to the fresh air outlet 5;

[0064] The outdoor air enters the compressor through the fresh air inlet 4 , the fresh air outlet 5 , and the circulating air outlet 9 .

[0065] In the present embodiment, an oxygen concentrator 3 is added to the outdoor unit 2. Preferably, the oxygen concentrator 3 is designed to be arranged at the top position inside the casing of the outdoor unit 2, and shares the same shell with the casing of the outdoor unit 2, so that the air conditioner as a whole is convenient to transport, and there is no need to install the oxygen concentrator 3 additionally. The outdoor unit 2 and the oxygen concentrator 3 can be installed together by simply fixing the outdoor unit 2, which is convenient to install.

[0066] The compressor on the oxygen concentrator 3 works to provide strong suction for indoor fresh air, so that outdoor air enters the room through the fresh air inlet 4 and circulates from the fresh air outlet 5 to the circulating air outlet 9 and returns to the compressor. In this process, the circulating air flow generated by the operation of the compressor enters the indoor unit 1 through the fresh air inlet 4, and part of the air flow is discharged from the air outlet 7 of the indoor unit 1, so that fresh air can be introduced into the room. The compressor on the oxygen concentrator 3 works to provide power for introducing fresh air into the room. Under this condition, the fan part of the indoor unit 1 does not need to run at a high speed to blow fresh air into the room. Even if the fan of the indoor unit 1 is not rotating, the compressor provides the power for introducing fresh air to introduce fresh air into the indoor unit 1, which can also achieve the introduction of fresh air into the room. Therefore, this design greatly reduces the fan noise of the indoor unit.

[0067] The air flow returning to the compressor is provided by the compressor to the oxygen production part for oxygen production. The oxygen production part of the oxygen generator 3 works so that the produced oxygen enters the oxygen inlet 6 from the oxygen outlet 8 and is discharged into the room from the air outlet 7. It is used when the outdoor air content is low. For example, in high-altitude areas, it is difficult to meet the indoor oxygen concentration demand by introducing fresh air. The oxygen production part of the oxygen generator 3 can work to produce oxygen, and the oxygen enters the oxygen inlet 6 from the oxygen outlet 8 and is discharged into the room from the air outlet 7, so as to effectively increase the indoor oxygen concentration. This design makes the air conditioner suitable for use in conditions where the outdoor air content is low, thereby broadening the scope of use of the air conditioner.

[0068] When the oxygen generator is not working and only fresh air needs to be introduced, the compressor can also transmit outdoor air from the oxygen outlet 8 of the oxygen generator to the oxygen inlet 6. The air enters the indoor unit 1 through the oxygen inlet 6 and is discharged into the room through the air outlet 7 of the indoor unit 1 to provide fresh air for the room.

[0069] Preferably, the fresh air inlet 4 is connected to a first fresh air duct 11 connected to the outdoors, and a second fresh air duct 12 is connected between the fresh air outlet 5 and the circulating air outlet 9 so that the two outlets are connected and the circulating air flows, and an oxygen pipeline 13 is connected between the oxygen inlet 6 and the oxygen outlet 8 so that the two outlets are connected and oxygen is delivered to the indoor unit 1.

[0070] Optionally, in an implementation of this embodiment, as Figure 2 As shown,

[0071] A filter 10 is provided in the indoor unit 1 , and the filter 10 is located on the fresh air circulation path between the fresh air inlet 4 and the fresh air outlet 5 .

[0072] In this embodiment, the fresh air inlet 4 and the fresh air outlet 5 are arranged at the air inlet of the indoor unit 1. When the compressor provides the air source for oxygen production for the oxygen production part, the filter 10 provided in the indoor unit 1 is cleverly utilized, and there is no need to add an additional filter. Compared with adding a filter to the outdoor unit 2, the filter provided in the indoor unit 1 can be cleaner because it is in the indoor environment. Therefore, the filter 10 of the indoor unit 1 can filter the air source that needs oxygen production and prevent dust from entering the interior of the oxygen generator 3.

[0073] Optionally, in an implementation of this embodiment, as Figure 3 As shown,

[0074] The oxygen production unit includes a molecular sieve group and a gas storage tank, the molecular sieve group is connected between the gas storage tank and the compressor, and the gas storage tank is connected to the oxygen outlet 8;

[0075] A second control valve and a heat exchanger are provided between the compressor and the molecular sieve group;

[0076] The second control valve is designed to control the air transmitted by the compressor to enter the molecular sieve group after entering the heat exchanger, or to enter the oxygen outlet 8.

[0077] Specifically, the molecular sieve group includes a first molecular sieve and a second molecular sieve;

[0078] A first one-way valve is provided between the first molecular sieve and the gas storage tank, a second one-way valve is provided between the second molecular sieve and the gas storage tank, and a first control valve is provided between the first molecular sieve, the second molecular sieve and the compressor;

[0079] The first control valve is designed to: control the first molecular sieve to output oxygen and control the second molecular sieve to output nitrogen, or control the first molecular sieve to output nitrogen and control the second molecular sieve to output oxygen.

[0080] In this embodiment, the oxygen production part includes at least two molecular sieves, namely the first molecular sieve and the second molecular sieve. The compressor provides air for the two molecular sieves. The first molecular sieve and the second molecular sieve are connected in parallel, so that air can enter the first molecular sieve and the second molecular sieve, so that the first molecular sieve and the second molecular sieve can perform oxygen production work alternately. The two molecular sieves perform oxygen production work alternately, 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 production part to continuously output oxygen.

[0081] like Figure 3 As shown, a first one-way valve is provided between the first molecular sieve and the gas storage tank, a second one-way valve is provided between the second molecular sieve and the gas storage tank, and a first control valve is provided between the first molecular sieve, the second molecular sieve and the compressor;

[0082] The first control valve is designed to: control the first molecular sieve to output oxygen and control the second molecular sieve to output nitrogen, or control the first molecular sieve to output nitrogen and control the second molecular sieve to output oxygen.

[0083] Preferably, the first control valve is a solenoid valve, which realizes the regulation of oxygen output and nitrogen emission of the first molecular sieve and the second molecular sieve through an electronic control program. For example, when the solenoid valve controls the first molecular sieve to output oxygen, it also controls the second molecular sieve to output nitrogen. The oxygen part enters the gas storage tank through the first one-way valve and is supplied to the indoor unit 1 when it needs to, and the nitrogen part is discharged outdoors. After that, the nitrogen separated by the first molecular sieve needs to be discharged, and the oxygen separated by the second molecular sieve also needs to be discharged. The solenoid valve controls the first molecular sieve to output nitrogen and controls the second molecular sieve to output oxygen, thereby realizing continuous oxygen output from the oxygen production unit.

[0084] like Figure 3 As shown, a second control valve and a heat exchanger are provided between the compressor and the first control valve;

[0085] The second control valve is designed to control the air delivered by the compressor to enter the heat exchanger and / or to enter the oxygen outlet 8 .

[0086] Preferably, the second control valve is a four-way valve, which has an air inlet and two air outlets, wherein the two air outlets can be switched with each other, one air outlet is connected to the heat exchanger, and the other air outlet is connected to the oxygen outlet 8. The four-way valve allows the air entering the oxygen production section from the compressor to be distributed as needed. For example, when the air conditioner does not need to perform additional oxygen production, the air entering the oxygen production section from the compressor is directly discharged from the oxygen outlet 8 through the four-way valve. When the air conditioner needs to perform additional oxygen production, the air entering the oxygen production section from the compressor enters the heat exchanger through the four-way valve. After heat exchange in the heat exchanger, the air reaches the molecular sieve treatment temperature and then enters the first molecular sieve and the second molecular sieve.

[0087] Optionally, in an implementation of this embodiment, as Figure 3 As shown,

[0088] A muffler is provided at the output end of the nitrogen, and the nitrogen discharged by the first molecular sieve and the second molecular sieve is discharged after passing through the muffler, thereby reducing the noise of nitrogen discharge.

[0089] Embodiment 2

[0090] like Figure 4-6 As shown, this embodiment provides an oxygen production control method, which is applied to the air conditioner in the first embodiment. The oxygen production control method includes:

[0091] Determine the oxygen production mode;

[0092] When the air conditioner is in normal working state, controlling the working state of the compressor and the oxygen generating unit according to the oxygen generating mode and the indoor oxygen concentration value;

[0093] The working states of the compressor and the oxygen production unit include:

[0094] A first working state in which the compressor inputs fresh air into the room and a second working state in which the compressor and the oxygen generator input oxygen into the room;

[0095] Wherein, the normal working state includes a cooling state or a heating state.

[0096] Specifically, the oxygen production mode includes an oxygen-rich mode and a forced oxygen-rich mode;

[0097] The controlling the working state of the compressor and the oxygen generator according to the oxygen production mode and the indoor oxygen concentration value comprises:

[0098] In the oxygen-enriched mode, according to whether the indoor oxygen concentration value is between the maximum preset oxygen concentration value and the minimum preset oxygen concentration value, the compressor is controlled to be in the first working state or the compressor and the oxygen generator are controlled to be in the second working state;

[0099] In the forced oxygen enrichment mode, the compressor and the oxygen generator are controlled to be in the second working state according to the relationship between the indoor oxygen concentration value and the maximum preset oxygen concentration value.

[0100] Wherein, in the oxygen-rich mode,

[0101] If the oxygen concentration value is less than or equal to the minimum preset oxygen concentration value, controlling the compressor to a first working state;

[0102] If the oxygen concentration value is greater than the minimum preset oxygen concentration value and less than the maximum preset oxygen concentration value, the compressor and the oxygen generator are controlled to be in the second working state.

[0103] In the forced oxygen-rich mode,

[0104] If the oxygen concentration value is less than the maximum preset oxygen concentration value, the compressor and the oxygen generator are controlled to be in a second working state.

[0105] In this embodiment, Figure 5 As shown, in the oxygen-rich mode, an oxygen concentration sensor is provided on the indoor unit 1 for obtaining the indoor oxygen concentration value. Preferably, the oxygen concentration sensor obtains the indoor oxygen concentration value Q once at a preset time interval, and compares Q with the maximum preset oxygen concentration value Q2 and the minimum preset oxygen concentration value Q1. If Q≥Q2, indicating that the indoor oxygen concentration reaches the upper limit requirement at this time, the oxygen generator 3 is not started, and the air conditioner is controlled to be in a normal working state, wherein the normal working state is the cooling state or the heating state of the air conditioner. If Q≤Q1, indicating that the indoor oxygen concentration is low at this time, the air conditioner is controlled to increase the fresh air working state under the normal working state. When the indoor oxygen concentration value is low, by directly introducing fresh air into the room, compared with selecting the oxygen generator 3 to generate oxygen and then input it into the room, it can not only achieve the effect of quickly improving the indoor oxygen concentration, but also reduce the utilization rate of the molecular sieve in the oxygen generator 3, and increase the service life of the molecular sieve.

[0106] If Q1<Q<Q2, it indicates that the indoor oxygen content is higher than the outdoor average oxygen content. At this time, the air conditioner is controlled to increase the oxygen production working state under the normal working state, that is, the oxygen generator 3 is started to work, and the compressor is used to provide power for air to enter the oxygen generator 3, and the four-way valve is switched to input air into the heat exchanger, the molecular sieve oxygen production is started, and the internal fan is started to transport oxygen through the oxygen outlet 8 to the oxygen inlet 6 and discharged into the room through the air outlet 7, so as to achieve the indoor oxygen enrichment level.

[0107] In this embodiment, the air conditioner switches between the fresh air working state and the oxygen production working state on the basis of the normal working state, so as to realize the rational utilization of the molecular sieve, which can not only quickly increase the indoor oxygen concentration, but also prolong the service life of the molecular sieve.

[0108] Among them, Q1=20.5%, Q2=23%.

[0109] like Figure 6 As shown, in the forced oxygen enrichment mode, an oxygen concentration sensor is provided on the indoor unit 1 to obtain the indoor oxygen concentration value. Preferably, the oxygen concentration sensor obtains the indoor oxygen concentration value Q once at a preset time interval, and compares Q with the maximum preset oxygen concentration value Q2. If Q≥Q2, it indicates that the indoor oxygen concentration reaches the upper limit requirement at this time, then the oxygen generator 3 is not started, and the air conditioner is controlled to be in a normal working state. If Q<Q2, the air conditioner is controlled to increase the oxygen production working state under the normal working state, that is, the oxygen generator 3 is started to work, and the compressor is used to provide power for air to enter the oxygen generator 3, the four-way valve is switched to input air into the heat exchanger, the molecular sieve is started to make oxygen, the internal fan is started, and the oxygen is transported through the oxygen outlet 8 to the oxygen inlet 6 and discharged to the room through the air outlet 7, so as to achieve forced oxygen enrichment in the room. The forced oxygen enrichment mode is suitable for special situations such as plateau areas, where users need to increase the indoor oxygen concentration through the oxygen generator 3 when the outdoor oxygen content is low.

[0110] Specifically, the compressor is in the first working state including:

[0111] The compressor on the oxygen concentrator 3 works to provide strong suction for indoor fresh air, so that outdoor air enters the room through the fresh air inlet 4 and circulates from the fresh air outlet 5 to the circulating air outlet 9 and returns to the compressor. In this process, the circulating air flow generated by the operation of the compressor enters the indoor unit 1 through the fresh air inlet 4, and part of the air flow is discharged from the air outlet 7 of the indoor unit 1, so that fresh air can be introduced into the room. The compressor on the oxygen concentrator 3 works to provide power for introducing fresh air into the room. Under this condition, the fan part of the indoor unit 1 does not need to run at a high speed to blow fresh air into the room. Even if the fan of the indoor unit 1 is not rotating, the compressor provides the power for introducing fresh air to introduce fresh air into the indoor unit 1, which can also achieve the introduction of fresh air into the room. Therefore, this design greatly reduces the fan noise of the indoor unit. When the oxygen generator is not working and only fresh air needs to be introduced, the compressor can also transmit outdoor air from the oxygen outlet 8 of the oxygen generator to the oxygen inlet 6. The air enters the indoor unit 1 through the oxygen inlet 6 and is discharged into the room through the air outlet 7 of the indoor unit 1 to provide fresh air for the room.

[0112] Specifically, the compressor and the oxygen production unit in the second working state include: controlling the second control valve to allow the air transmitted by the compressor to enter the heat exchanger, and then enter the first molecular sieve and the second molecular sieve after reaching a preset temperature;

[0113] The first control valve is controlled to make the first molecular sieve output oxygen and the second molecular sieve output nitrogen. The oxygen enters the storage tank through the first one-way valve, and enters the oxygen outlet 8 from the storage tank. The nitrogen is discharged outdoors through the muffler, or,

[0114] The first control valve is controlled to make the first molecular sieve output nitrogen and the second molecular sieve output oxygen. The oxygen enters the storage tank through the first one-way valve, enters the oxygen outlet 8 from the storage tank, and the nitrogen is discharged to the outside through the muffler. The working process of the oxygen production unit is as follows: the air entering the oxygen production unit from the compressor enters the heat exchanger through the four-way valve. After heat exchange in the heat exchanger, the air reaches the molecular sieve processing temperature and enters the first molecular sieve and the second molecular sieve. When the solenoid valve controls the first molecular sieve to output oxygen, it also controls the second molecular sieve to output nitrogen. The oxygen part enters the gas storage tank through the first one-way valve and is supplied to the indoor unit 1 when needed. The nitrogen part is discharged to the outside through the muffler. Thereafter, the nitrogen separated by the first molecular sieve needs to be discharged, and the oxygen separated by the second molecular sieve also needs to be discharged. The solenoid valve controls the first molecular sieve to output nitrogen and controls the second molecular sieve to output oxygen. The oxygen part enters the gas storage tank through the second one-way valve and is supplied to the indoor unit 1 when needed. The nitrogen part is discharged to the outside through the muffler, thereby realizing the continuous oxygen output of the oxygen production unit.

[0115] Embodiment 3

[0116] This embodiment provides an electronic device, including:

[0117] a memory for storing one or more computer executable instructions;

[0118] 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.

[0119] In this embodiment, the electronic device determines the oxygen production mode; when the air conditioner is in normal working state, the working state of the compressor and the oxygen production unit is controlled according to the oxygen production mode and the indoor oxygen concentration value; the working state of the compressor and the oxygen production unit includes: a first working state in which the compressor inputs fresh air into the room and a second working state in which the compressor and the oxygen production unit input oxygen into the room; in the oxygen-enriched mode, an oxygen concentration sensor is provided on the indoor unit 1 for obtaining the indoor oxygen concentration value, and the oxygen concentration sensor obtains the indoor oxygen concentration value Q once at a preset time interval, compares Q with the maximum preset oxygen concentration value Q2 and the minimum preset oxygen concentration value Q3. The preset oxygen concentration value Q1 is compared. If Q≥Q2, it indicates that the indoor oxygen concentration has reached the upper limit requirement at this time, then the oxygen generator 3 will not be started, and the air conditioner will be controlled to be in the normal working state, wherein the normal working state is the cooling state or the heating state of the air conditioner. If Q≤Q1, it indicates that the indoor oxygen concentration is low at this time, then the air conditioner will be controlled to increase the fresh air working state under the normal working state. When the indoor oxygen concentration value is low, by directly introducing fresh air into the room, compared with selecting the oxygen generator 3 to generate oxygen and then input it into the room, it can not only achieve the effect of quickly increasing the indoor oxygen concentration, but also reduce the utilization rate of the molecular sieve in the oxygen generator 3, and increase the service life of the molecular sieve.

[0120] If Q1<Q<Q2, it indicates that the indoor oxygen content is higher than the outdoor average oxygen content. At this time, the air conditioner is controlled to increase the oxygen production working state under the normal working state, that is, the oxygen generator 3 is started to work, and the compressor is used to provide power for air to enter the oxygen generator 3, and the four-way valve is switched to input air into the heat exchanger, the molecular sieve oxygen production is started, and the internal fan is started to transport oxygen through the oxygen outlet 8 to the oxygen inlet 6 and discharged into the room through the air outlet 7, so as to achieve the indoor oxygen enrichment level.

[0121] In this embodiment, the air conditioner switches between the fresh air working state and the oxygen production working state on the basis of the normal working state, so as to realize the rational utilization of the molecular sieve, which can not only quickly increase the indoor oxygen concentration, but also prolong the service life of the molecular sieve.

[0122] In the forced oxygen enrichment mode, an oxygen concentration sensor is provided on the indoor unit 1 to obtain the indoor oxygen concentration value. The oxygen concentration sensor obtains the indoor oxygen concentration value Q once at a preset time interval, and compares Q with the maximum preset oxygen concentration value Q2. If Q≥Q2, it indicates that the indoor oxygen concentration reaches the upper limit requirement at this time, then the oxygen generator 3 is not started, and the air conditioner is controlled to be in a normal working state. If Q<Q2, the air conditioner is controlled to increase the oxygen production working state under the normal working state, that is, the oxygen generator 3 is started to work, and the compressor is used to provide power for air to enter the oxygen generator 3, the four-way valve is switched to input air into the heat exchanger, the molecular sieve oxygen is started, the internal fan is started, and the oxygen is transported through the oxygen outlet 8 to the oxygen inlet 6 and discharged to the room through the air outlet 7, so as to achieve forced oxygen enrichment in the room. The forced oxygen enrichment mode is suitable for special situations such as plateau areas, where users need to increase the indoor oxygen concentration through the oxygen generator 3 when the outdoor oxygen content is low.

[0123] In summary, the ingenious conception of the air conditioner and the oxygen production control method is:

[0124] First, the compressor on the oxygen concentrator works to provide strong suction for indoor fresh air. The circulating airflow generated by the compressor enters the indoor unit from the fresh air inlet, and part of the air is discharged from the air outlet of the indoor unit to introduce fresh air into the room, or is discharged from the oxygen inlet of the oxygen concentrator to the indoor unit, and then discharged from the air outlet of the indoor unit. The compressor on the oxygen concentrator works to provide power for introducing fresh air into the room. Under this condition, the fan part of the indoor unit does not need to run at a high speed to blow fresh air into the room. Therefore, this design reduces the fan noise of the indoor unit to a large extent. The oxygen concentrator of the oxygen concentrator works to make the oxygen produced enter the oxygen inlet from the oxygen outlet and be discharged into the room from the air outlet. When the outdoor air content is low, it is difficult to meet the indoor oxygen concentration requirement by introducing fresh air. Then, the oxygen concentrator of the oxygen concentrator can work to produce oxygen to effectively increase the indoor oxygen concentration. This design makes the air conditioner suitable for use in conditions with low outdoor air content, broadening the scope of use of the air conditioner.

[0125] Second, the oxygen production section is designed to include at least two molecular sieves, and a compressor provides air for the two molecular sieves. The first molecular sieve and the second molecular sieve are connected in parallel, so that air can enter the first molecular sieve and the second molecular sieve at the same time, so that the first molecular sieve and the second molecular sieve can produce oxygen at the same time. The two molecular sieves produce oxygen at the same time, so that when one of the molecular sieves is outputting oxygen, the other molecular sieve is discharging 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 production section to continuously output oxygen.

[0126] Third, in the oxygen enrichment mode of the oxygen production control method, by comparing the oxygen concentration value with the maximum preset oxygen concentration value and the minimum preset oxygen concentration value, when the oxygen concentration value is ≤ the minimum preset oxygen concentration value, it indicates that the indoor oxygen concentration is low at this time, and the air conditioner is controlled to increase the fresh air working state under the normal working state. When the indoor oxygen concentration value is low, by directly introducing fresh air into the room, compared with selecting the oxygen generator to generate oxygen and then input it into the room, it can not only achieve the effect of rapidly increasing the indoor oxygen concentration, but also reduce the utilization rate of the molecular sieve in the oxygen generator and increase the service life of the molecular sieve. When the oxygen concentration value is between the maximum preset oxygen concentration value and the minimum preset oxygen concentration value, it indicates that the indoor oxygen content is higher than the outdoor average oxygen content. At this time, the air conditioner is controlled to increase the oxygen production working state under the normal working state to achieve the indoor oxygen enrichment degree. By switching the fresh air working state and the oxygen production working state of the air conditioner on the basis of the normal working state, the rational use of the molecular sieve is realized, which can not only achieve the rapid increase of the indoor oxygen concentration, but also extend the service life of the molecular sieve.

[0127] Fourth, the fresh air inlet and outlet are set at the air inlet of the indoor unit. When the compressor provides the air source for oxygen production to the oxygen generator, the built-in filter in the indoor unit is cleverly used without the need for additional filters. Compared with adding filters to the outdoor unit, the built-in filter of the indoor unit can be cleaner because it is in the indoor environment. Therefore, the filter of the indoor unit can filter the air source that needs oxygen production and prevent dust from entering the interior of the oxygen generator.
