It should be understood that such data may be interchanged under appropriate circumstances so as to implement the embodiments of the present disclosure described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion.

[0036] Unless otherwise specified, the term "plurality" means two or more.

[0037] In the embodiments of the present disclosure, the character " / " indicates that the objects before and after are in an "or" relationship. For example, A / B means: A or B.

[0038] The term "and / or" is a description of the associated relationship of an object and indicates that three relationships may exist. For example, A and / or B means: A or B, or, A and B these three relationships.

[0039] In combination withFigure 1 As shown in Figure 1 , an embodiment of the present disclosure provides a method for controlling a carbon dioxide removal machine, which includes:

[0040] S01, controlling the state of the air flow switch assembly according to the adsorption state of the adsorption module;

[0041] S02, controlling the operation of the heating device according to the state of the air flow switch assembly and the temperature of the adsorption module;

[0042] Wherein, the air flow switch assembly opens the first air outlet and closes the second air outlet in the first state, and closes the first air outlet and opens the second air outlet in the second state.

[0043] By using the method for controlling a carbon dioxide removal machine provided by the embodiment of the present disclosure, the state of the air flow switch assembly can be controlled according to the adsorption state of the adsorption module, so that after the adsorption module is saturated, the air flow passing through the adsorption module is directed to the outside, and the operation of the heating device is controlled to release carbon dioxide from the adsorption module under the heating effect. When the carbon dioxide concentration on the adsorption module is released, the adsorption state of the adsorption module is converted to the no-load state, and then the air flow passing through the adsorption module is switched to the inside to continue absorbing carbon dioxide in the air flow. By repeating the operation, the carbon dioxide content in the room can be fundamentally reduced, and the efficiency of removing carbon dioxide can be improved.

[0044] Optionally, controlling the state of the air flow switch assembly according to the adsorption state of the adsorption module includes: when the adsorption state of the adsorption module is the no-load state, controlling the air flow switch assembly to be in the first state; when the adsorption state of the adsorption module is the saturated state, controlling the air flow switch assembly to be in the second state. In this way, according to the no-load state of the adsorption module, the air flow switch assembly is controlled to be in the first state, that is, the air flow passing through the adsorption module is directed to the inside of the room, and the no-load adsorption module is used to adsorb carbon dioxide in the air flow, efficiently reducing the carbon dioxide content in the room. And the saturated state of the adsorption module indicates that it is full of adsorbed carbon dioxide. At this time, controlling the air flow switch assembly to be in the second state and directing the air flow passing through the adsorption module to the outside is convenient for discharging the adsorbed carbon dioxide on the adsorption module to the outside, making the adsorption module return to the no-load state, and then continuously repeating the process of absorbing carbon dioxide from the room and releasing it to the outside, which can fundamentally and efficiently reduce the carbon dioxide content in the room.

[0045] Optionally, the no-load state of the adsorption module means that the efficiency of the adsorption module releasing carbon dioxide is lower than a certain value.

[0046] Optionally, the saturated state of the adsorption module means that the efficiency of the adsorption module adsorbing carbon dioxide is higher than a certain value.

[0047] Optionally, when the adsorption state of the adsorption module is the no-load state, controlling the air flow switch assembly to be in the first state includes: after the adsorption state of the adsorption module reaches the set duration of the no-load state, controlling the air flow switch assembly to be in the first state. In this way, after the adsorption module releases carbon dioxide and reaches the no-load state, there is enough time for cooling. After cooling, the air flow switch assembly enters the first state. The cooled adsorption module can adsorb carbon dioxide in the room more efficiently and prevent the waste heat of the adsorption module from being discharged into the room, affecting the stability of the indoor temperature.

[0048] Optionally, the set duration is greater than or equal to 20 seconds and less than or equal to 40 seconds. In this way, cooling is carried out between 20 seconds and 40 seconds after the adsorption state of the adsorption module reaches the no-load state, and more sufficient cooling can be achieved.

[0049] Optionally, the set duration is 30 seconds. In this way, after the adsorption module reaches the no-load state, it is cooled for 30 seconds, which can achieve sufficient cooling and will not cause excessive cooling to discharge the air after removing carbon dioxide outdoors, better reducing the concentration of carbon dioxide in the room.

[0050] Optionally, determine the adsorption state of the adsorption module according to the change in the carbon dioxide concentration difference on both sides of the adsorption module. In this way, the adsorption state of the adsorption module can be judged more accurately, and then the state of the air flow switch assembly can be controlled more accurately, improving the control accuracy and enhancing the working efficiency of reducing the carbon dioxide concentration.

[0051] Optionally, the carbon dioxide concentration difference on both sides of the adsorption module is obtained by subtracting the carbon dioxide concentration on the leeward side of the adsorption module from the carbon dioxide concentration on the windward side of the adsorption module. In this way, the carbon dioxide concentration difference on both sides of the adsorption module can be obtained more accurately, and then the adsorption state of the adsorption module can be judged more accurately.

[0052] Optionally, when the carbon dioxide concentration difference decreases from large to small and is less than or equal to a first preset value, it is determined that the adsorption state of the adsorption module is a saturated state; when the carbon dioxide concentration difference increases from small to large and is greater than or equal to a second preset value, it is determined that the adsorption state of the adsorption module is an empty-load state. In this way, when the carbon dioxide concentration difference decreases from large to small, it indicates that the adsorption capacity of the adsorption module for carbon dioxide decreases. When the carbon dioxide concentration difference reaches less than or equal to the first preset value, it is determined that the adsorption module reaches the saturated state. At this time, the adsorption module is fully adsorbed with carbon dioxide. When the carbon dioxide concentration difference increases from small to large, it indicates that the amount of carbon dioxide released by the adsorption module is getting smaller and smaller. When the carbon dioxide concentration difference reaches greater than or equal to the second preset value, it is determined that the adsorption module reaches the empty-load state. At this time, the adsorption module can better adsorb carbon dioxide. Therefore, by the change of the carbon dioxide concentration difference on both sides of the adsorption module, it is more accurate to determine the adsorption state of the adsorption module, and it can better control the state of the air flow switch component through the adsorption state of the adsorption module, improve the control accuracy, and enhance the working efficiency of reducing the carbon dioxide concentration.

[0053] Optionally, the first preset value is greater than or equal to 0 ml / m³ and less than or equal to 80 ml / m³. In this way, within the range of 0 to 80 ml / m³ of the carbon dioxide concentration difference on both sides of the adsorption module, the decrease in the adsorption capacity of the adsorption module can be fully reflected, and it is more accurate to determine the adsorption state of the adsorption module as the saturated state at this time.

[0054] Optionally, the first preset value is 50 ml / m³. In this way, when the carbon dioxide concentration difference on both sides of the adsorption module is 50 ml / m³, it is more accurate to determine the adsorption state of the adsorption module as the saturated state at this time.

[0055] Optionally, the second preset value is less than or equal to 0 ml / m³ and greater than or equal to -80 ml / m³. Within the range of -80 to 0 ml / m³ of the carbon dioxide concentration difference on both sides of the adsorption module, the decrease in the efficiency of the adsorption module releasing carbon dioxide can be fully reflected, and it is more accurate to determine the adsorption state of the adsorption module as the empty-load state at this time.

[0056] Optionally, the second preset value is -50 ml / m³. In this way, when the carbon dioxide concentration difference on both sides of the adsorption module is -50 ml / m³, it is more accurate to determine the adsorption state of the adsorption module as the empty-load state at this time.

[0057] Optionally, the adsorption state of the adsorption module is determined according to the working duration of the adsorption module in the state of the corresponding air flow switch component. In this way, by judging the adsorption state of the adsorption module through the working duration of the adsorption module in different states of the air flow switch component, it is simpler and more reliable, and the system runs more stably.

[0058] Optionally, after the adsorption module operates for a first preset duration in the first state of the air flow switch assembly, it is determined that the adsorption module is in a saturated state. In this way, after the adsorption module operates for a certain duration in the first state of the air flow switch assembly, it indicates that the adsorption module has adsorbed a relatively large amount of carbon dioxide. At this time, determining the adsorption state of the adsorption module as a saturated state is simpler and more reliable.

[0059] Optionally, the first preset duration is greater than or equal to 3 minutes and less than or equal to 5 minutes. In this way, the existing adsorption materials can basically adsorb carbon dioxide completely within 3 to 5 minutes. The adsorption module operates for 3 to 5 minutes in the first state of the air flow switch assembly, and it is determined that the adsorption state of the adsorption module reaches the saturated state, which can accurately determine that the adsorption state of the adsorption module reaches the saturated state.

[0060] Optionally, the first preset duration is 4 minutes. In this way, the adsorption module operates for 4 minutes in the first state of the air flow switch assembly, which can fully indicate that the adsorption state of the adsorption module reaches the saturated state.

[0061] Optionally, after the adsorption module operates for a second preset duration in the second state of the air flow switch assembly, it is determined that the adsorption module is in an empty load state. In this way, generally, after the adsorption module releases carbon dioxide for more than a certain duration, it can fully indicate that the adsorption module releases a relatively large amount of carbon dioxide. At this time, determining the adsorption state of the adsorption module as an empty load state is more accurate.

[0062] Optionally, the second preset duration is greater than or equal to 1 minute and less than or equal to 2 minutes. In this way, generally, after the adsorption module releases carbon dioxide for 1 to 2 minutes, it can fully indicate that the adsorption module releases a relatively large amount of carbon dioxide. At this time, determining the adsorption state of the adsorption module as an empty load state is more accurate.

[0063] Optionally, the second preset duration is 1.5 minutes. In this way, after the adsorption module releases carbon dioxide for 1.5 minutes, it is determined that the adsorption state of the adsorption module is in an empty load state, which is more accurate and reliable.

[0064] Optionally, the operation of the heating device is controlled according to the state of the air flow switch assembly and the temperature of the adsorption module, including: when the air flow switch assembly is in the first state, controlling the heating device to stop operating; when the air flow switch assembly is in the second state, controlling the operation of the heating device according to the temperature of the adsorption module. In this way, it is determined whether the moisture absorption module needs to be heated according to the state of the air flow switch assembly, and the amount of heating of the moisture absorption module is controlled according to the temperature of the adsorption module, so that the operation of the heating device can be controlled more precisely, the adsorption module can be heated better, the heating efficiency can be improved, and further the efficiency of the adsorption module releasing carbon dioxide can be increased.

[0065] Optionally, the operation of the heating device is controlled according to the temperature of the adsorption module, including: when the temperature of the adsorption module is greater than or equal to the first temperature set value, controlling the heating device to stop operating; when the temperature of the adsorption module is less than the second temperature set value, controlling the heating device to start operating. In this way, the adsorption module can be maintained within a certain temperature range, preventing the carbon dioxide release efficiency of the adsorption module from being affected by too high or too low temperature, and thus efficiently removing carbon dioxide in the room.

[0066] Optionally, the first temperature set value is greater than or equal to 100 degrees and less than or equal to 110 degrees. In this way, when the temperature of the adsorption module exceeds 100 to 110 degrees, the carbon dioxide release of the adsorption module will be affected. After the temperature exceeds this temperature range, stopping the operation of the heating device can prevent the temperature of the adsorption module from continuing to rise, thereby increasing the amount of carbon dioxide released.

[0067] Optionally, the first temperature set value is 100 degrees. In this way, when the temperature of the adsorption module exceeds 100 degrees, the operation of the heating device stops, keeping the adsorption device at a reasonable temperature and better releasing carbon dioxide.

[0068] Optionally, the second temperature set value is greater than or equal to 85 degrees and less than or equal to 95 degrees. In this way, when the temperature of the adsorption module is lower than 85 to 95 degrees, insufficient heat will affect the release of carbon dioxide. After the temperature is lower than this temperature range, starting the heating device to heat the adsorption module can effectively improve the carbon dioxide release efficiency of the adsorption module.

[0069] Optionally, the second temperature set value is 90 degrees. In this way, when the temperature of the adsorption module is lower than 90 degrees, the efficiency of releasing carbon dioxide is relatively low. At this time, starting the heating device to heat the adsorption module can more efficiently improve the carbon dioxide release efficiency of the adsorption module.

[0070] Combined with Figure 2 As shown, the embodiments of the present disclosure provide another method for controlling a carbon dioxide removal machine. In some alternative embodiments, before controlling the state of the air flow switch assembly according to the adsorption state of the adsorption module, it further includes:

[0071] S03, obtaining the indoor carbon dioxide concentration;

[0072] S04, when the indoor carbon dioxide concentration is greater than or equal to the first concentration value, starting the carbon dioxide removal machine and judging the adsorption state of the adsorption module.

[0073] In this way, the carbon dioxide removal machine is automatically started only when the indoor carbon dioxide concentration reaches a certain value, and at the same time, the adsorption state of the adsorption module is judged, which is more intelligent and reliable.

[0074] Optionally, the first concentration value is greater than or equal to 1400 milliliters per cubic meter and less than or equal to 1600 milliliters per cubic meter. In this way, when the carbon dioxide concentration in the room exceeds 1400 to 1600 milliliters per cubic meter, it indicates that the carbon dioxide concentration in the room is relatively high and carbon dioxide removal is required. At this time, turning on the carbon dioxide removal machine can more intelligently reduce the carbon dioxide concentration in the room.

[0075] Optionally, the first concentration value is 1500 milliliters per cubic meter. In this way, when the carbon dioxide concentration in the room reaches 1500 milliliters per cubic meter, turning on the carbon dioxide removal machine can more intelligently keep the carbon dioxide concentration in the room from exceeding the standard.

[0076] In some alternative embodiments, after controlling the operation of the heating device according to the state of the air flow switch assembly and the temperature of the adsorption module, it further includes:

[0077] S05, when the carbon dioxide concentration in the room is less than the second concentration value, turn off the carbon dioxide removal machine.

[0078] In this way, when the carbon dioxide concentration in the room is lower than a certain value, the carbon dioxide removal machine is automatically turned off, which is more intelligent and reliable, and more energy-saving and environmentally friendly.

[0079] Optionally, the second concentration value is greater than or equal to 700 milliliters per cubic meter and less than or equal to 900 milliliters per cubic meter. In this way, when the carbon dioxide concentration in the room is lower than 700 to 900 milliliters per cubic meter, it indicates that the carbon dioxide concentration in the room is moderate. At this time, turning off the carbon dioxide removal machine can avoid unnecessary energy waste and is more energy-saving and environmentally friendly.

[0080] Optionally, the second concentration value is 800 milliliters per cubic meter. In this way, when the carbon dioxide concentration in the room reaches 800 milliliters per cubic meter, it indicates that the carbon dioxide concentration in the room meets the standard. At this time, turning off the carbon dioxide removal machine can avoid unnecessary energy waste and is more energy-saving and environmentally friendly.

The processor 1000 executes functional applications and data processing by running the program instructions / modules stored in the memory 1001, that is, implements the method for controlling the carbon dioxide removal machine in the above embodiments.

[0089] Combined with Figures 4 - 5As shown in the figure, an embodiment of the present disclosure provides a carbon dioxide removal machine, including: a first air outlet 500 communicating with the interior of the room, a second air outlet 600 communicating with the exterior of the room, an air flow switch assembly 200, an adsorption module 300, and a heating device 400. The air flow switch assembly 200 is configured to open the first air outlet 500 and close the second air outlet 600 in a first state, and close the first air outlet 500 and open the second air outlet 600 in a second state. It further includes: the above-mentioned device for controlling the carbon dioxide removal machine.

[0090] In some embodiments, a carbon dioxide removal machine includes: a housing 100, an air flow switch assembly 200, an adsorption module 300, and a heating device 400. The housing 100 includes a first air outlet 500 communicating with the interior of the room and a second air outlet 600 communicating with the exterior of the room; the air flow switch assembly 200 is configured to open the first air outlet 500 and close the second air outlet 600 in a first state, and close the first air outlet 500 and open the second air outlet 600 in a second state. The adsorption module 300 is disposed inside the housing 100 and is configured to adsorb carbon dioxide at normal temperature and release carbon dioxide in a heated state; the heating device 400 is disposed on one side or inside the adsorption module 300 and is configured to heat the adsorption module 300.

[0091] By using the carbon dioxide removal machine disclosed in this embodiment, the carbon dioxide in the indoor air can be adsorbed by the adsorption module 300 disposed inside the housing 100. Due to the characteristic that the adsorption module 300 adsorbs carbon dioxide at normal temperature and releases carbon dioxide in a heated state, the adsorption module 300 is intermittently heated by the heating device 400, and the carbon dioxide released by the adsorption module 300 is discharged to the outside through the second air outlet 600, effectively removing the carbon dioxide in the indoor air and improving the user experience.

[0092] Optionally, both the first air outlet 500 and the second air outlet 600 are disposed on the housing 100, and the first air outlet 500 communicates the interior of the housing 100 with the interior of the room, and the second air outlet 600 communicates the interior of the housing 100 with the exterior of the room. In this way, the air flow processed by adsorption inside the housing 100 is discharged into the room through the first air outlet 500, and the carbon dioxide released by heating the adsorption module 300 is discharged to the outside through the second air outlet 600, effectively removing the carbon dioxide in the indoor air and improving the user experience.

[0093] Optionally, the air flow switch assembly 200 includes: a first switching valve 210 and a second switching valve 220. The first switching valve 210 is disposed within the first air outlet 500; the second switching valve 220 is disposed within the second air outlet 600. In this way, by controlling the first switching valve 210 to open and the second switching valve 220 to close, the first air outlet 500 is opened and the second air outlet 600 is closed, or by controlling the first switching valve 210 to close and the second switching valve 220 to open, the first air outlet 500 is closed and the second air outlet 600 is opened, so that the air after adsorption treatment is discharged into the room through the first air outlet 500, and the carbon dioxide released by the adsorption module 300 is discharged to the outside through the second air outlet 600, effectively removing carbon dioxide in the indoor air and improving the user experience.
