Detailed Description

Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.

When the air conditioner is used, the indoor is usually in a closed state, and when no person is in the indoor, the oxygen content in the indoor is about 20%, and when the number of persons in the indoor is increased, the carbon dioxide concentration in the indoor is increased, and the oxygen content is gradually reduced. Wherein when the indoor oxygen content is reduced to below 19.6%, the oxygen content will affect the health of human body. When the oxygen concentration is reduced to 19.5% -12%, judgment of a person is deteriorated, respiration pulse is accelerated, fatigue and harmony are deteriorated, and when the indoor oxygen concentration is 10% -12%, the person stays indoors for a few minutes and suffers from respiratory obstruction, poor circulation, extreme fatigue and incapacity. On the other hand, increasing the oxygen concentration within a certain range can make people feel more comfortable, for example, when the oxygen concentration is 21% -23.5%, people feel pleasant, and when the oxygen concentration is too high, people are caused to be drunk by oxygen.

Based on the above, in order to maintain the indoor oxygen concentration at a proper concentration to create a comfortable and healthy indoor environment for the user, and to solve the problems that the introduced fresh air affects the indoor temperature and the increase of the indoor oxygen concentration is limited when the introduced outdoor fresh air is used for oxygenation, the embodiments of the present invention provide an air conditioner, an oxygenation module, and a control method of the air conditioner.

The air conditioner in the embodiment can be a common household air conditioner, an air duct air conditioner and the like, the operation mode and principle of the air duct air conditioner are the same as those of the common household air conditioner, and the air duct air conditioner is mainly taken as an example for explanation.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Fig. 1 is a schematic view of an air conditioner, the basic structure of which can be understood in conjunction with fig. 1, in which the air conditioner performs a cooling/heating cycle of the air conditioner by using a compressor, a condenser (outdoor heat exchanger), an expansion valve, and an evaporator (indoor heat exchanger). Wherein the refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies a refrigerant to the air that has been conditioned and heat-exchanged.

The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

The expansion valve expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigerating effect by heat exchange with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.

The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.

An air conditioner according to some embodiments of the present application includes an air conditioner indoor unit installed in an indoor space. The indoor unit, i.e., the indoor unit, is connected to an outdoor unit, i.e., the outdoor unit, installed in an outdoor space through a pipe. The outdoor unit of the air conditioner may be provided with a compressor, an outdoor heat exchanger, an outdoor fan, an expander, and the like for a refrigeration cycle, and the indoor unit of the air conditioner may be provided with an indoor heat exchanger and an indoor fan.

An air conditioner according to an embodiment of the present invention is described below with reference to fig. 2. Fig. 2 is a block diagram of an air conditioner according to an embodiment of the present invention. As shown in fig. 2, the air conditioner 10 includes an indoor unit 1, an outdoor unit 2, an oxygen concentration sensor 3, an oxygen increasing module 4, and a controller 5.

The oxygen concentration sensor 3 is disposed in the indoor unit 1, and for example, the oxygen concentration sensor 3 may be disposed inside the indoor unit 1 or on a casing of the indoor unit 1 to directly contact with indoor air so as to detect the indoor oxygen concentration.

In some embodiments, the outdoor unit 2 and the oxygenation module 4 according to the embodiments of the present invention may be described with reference to fig. 3, fig. 3 is a schematic view of an outdoor unit according to an embodiment of the present invention, and arrows in fig. 2 indicate air flowing directions.

Specifically, as shown in fig. 3, the oxygen increasing module 4 is disposed on an air inlet side of the outdoor unit 2, and is configured to enrich oxygen flowing through the air and deliver the enriched oxygen to an air outlet of the indoor unit 1. The air inlet side of the outdoor unit 2 is provided with an air inlet, the oxygen increasing module 4 can be set to be in a shape matched with the size and the shape of the air inlet, so that the oxygen increasing module 4 is just arranged at the air inlet, air in an outdoor environment flows into the outdoor unit 2 only after flowing through the oxygen increasing module 4 from the air inlet, the oxygen increasing module 4 can be ensured to be fully contacted with the flowing air, oxygen in the air can be enriched as much as possible, and the oxygen increasing rate of the oxygen increasing module 4 can be ensured.

Further, when the oxygen increasing module 4 is in operation, when air flows through the oxygen increasing module 4, the oxygen increasing module 4 separates oxygen in the air, and discharges other gas components such as nitrogen in the air from the air outlet side of the outdoor unit 2.

In some embodiments, as shown in fig. 2, the controller 5 is connected to the oxygen concentration sensor 3 and the oxygen increasing module 4, and specifically, the controller 4 can receive the indoor oxygen concentration detected by the oxygen concentration sensor 3 in real time and control the operating state of the oxygen increasing module 4 according to the indoor oxygen concentration.

The controller 4 may be a Processor with data Processing and analyzing functions, such as a Central Processing Unit (CPU) in an air conditioner, and the like, and the controller 4 may include a time monitoring Unit, a determining Unit, a control Unit, and the like for Processing and analyzing data.

Specifically, the controller 5 is configured to: receiving the indoor oxygen concentration and acquiring the current operation time point of the compressor.

The indoor oxygen concentration detected by the oxygen concentration sensor 3 can be directly obtained, and the indoor oxygen concentration is an important factor influencing the health and comfort of a user, so that the indoor oxygen concentration can be used as a reference condition to ensure the effect of the oxygen increasing module 4 on enriching oxygen flowing through the air.

The current operating time point is understood to be the current operating time point of the compressor of the air conditioner 10, for example, the current operating time point of the compressor is determined to be 8 hours, 5 minutes, 12 hours, 35 minutes, 14 hours, 17 hours, 20 minutes, and the like. It will be appreciated that the oxygen concentration in the outdoor air is constantly changing during the day, for example, at 14-18 hours the oxygen concentration in the outdoor air is at a higher level and the oxygen concentration in the outdoor air is lower for the remaining time period, wherein the time periods corresponding to the oxygen concentrations in the different outdoor environments may be stored by the memory unit in the controller 4. Based on this, when controlling the operation state of the oxygen increasing module 4, the current operation time point of the air conditioner 10 may be used as a reference condition to ensure the effect of the oxygen increasing module 4 enriching the oxygen flowing through the air.

In some embodiments, the on-off state of the oxygenation module 4 is controlled according to the indoor oxygen concentration.

It can be known from the above that, when the indoor oxygen concentration is too low, the health and even the life safety of human body will be affected, and when the indoor oxygen concentration is too high, the "drunk oxygen" phenomenon will occur. Therefore, when the indoor oxygen concentration is low, the indoor oxygen concentration needs to be increased to meet the requirements of health and comfort of users, after the controller 5 controls the oxygen increasing module 4 to be started and operated, the oxygen increasing module 4 enriches oxygen in air flowing through, and transmits the enriched oxygen to the air outlet of the indoor unit 1 to increase the indoor oxygen concentration. When the indoor oxygen concentration is in a proper range or the indoor oxygen concentration is higher, the indoor oxygen concentration does not need to be further improved, the controller 5 controls the oxygen increasing module 4 not to be started or stopped to operate, the dynamic state of the indoor oxygen concentration is maintained in a proper range, a fresh oxygen-enriched environment is provided for a human body, and the health of a user is facilitated, and the comfort of the user is improved.

And, in other embodiments, the operating mode of the oxygen increasing module 4 is controlled according to the current operating time point when the oxygen increasing module 4 is operated, wherein the oxygen increasing module 4 has different oxygen increasing rates in different operating modes.

Specifically, controlling the operation mode of the oxygen increasing module 4 may include controlling the oxygen increasing rate when the oxygen increasing module 4 operates. The principle of oxygen enrichment of the oxygenation module 4 is as follows: when the oxygen increasing module 4 is powered on, the oxygen increasing module 4 separates oxygen from air flowing through, and discharges other gas components such as nitrogen from the air outlet side of the outdoor unit 2. The amount of air flowing in between the air inlet side units of the outdoor unit 2 is constant, and if the oxygen concentration in the outdoor air is constant all the time, the oxygen amount in the air flowing through the oxygen increasing module 4 separated in unit time, namely the oxygen increasing rate, is constant when the oxygen increasing module works.

As can be seen from the above embodiments, the oxygen concentration in the outdoor air differs depending on the current operating point at which the air conditioner 10 is operating. Based on this, for the same oxygen increasing module 4, when the oxygen increasing module 4 is powered on to work, if a working state is always maintained, if the current operation time point is a time period in which the oxygen concentration in the outdoor air is at a high level in a day, the oxygen increasing rate when the oxygen increasing module 4 works is relatively high, and if the current operation time point is a time period in which the oxygen concentration in the outdoor air is at a normal level in a day, the oxygen increasing rate when the oxygen increasing module 4 works is lower than the oxygen increasing rate when the oxygen concentration in the outdoor air is at a high level. Therefore, in order to control the oxygen increasing module 4 to maintain a stable oxygen enrichment efficiency, the working mode of the oxygen increasing module 4 can be controlled according to the current running time point, so as to ensure that the indoor oxygen concentration can be reasonably and stably increased.

According to the air conditioner 10 provided by the embodiment of the invention, the indoor oxygen concentration can be monitored in real time by arranging the oxygen concentration sensor 3 in the indoor unit 1. And set up oxygenation module 4 in the air inlet side of off-premises station 2, when indoor oxygen concentration is lower, controller 5 can control oxygenation module 4 and open to carry the oxygen of oxygenation module 4 enrichment to indoor, and then effectively promote indoor oxygen concentration, and when indoor oxygen concentration is higher, controller 5 can control oxygenation module 4 stop working, thereby realize the dynamic adjustment to indoor oxygen concentration. And, when oxygenation module 4 moves, controller 5 can also control the different mode of operation of oxygenation module 4 according to the change of outdoor different time quantum atmospheric oxygen content, through adopting the oxygenation scheme of time quantum, multi-mode, can realize carrying out accurate and high-efficient oxygenation for indoor environment space to can build a comfortable indoor environment for the human body, can not influence indoor temperature, satisfy the healthy demand of human body and guarantee human comfort level.

In addition, the oxygen increasing module 4 of the present embodiment may be applied to the air conditioner 10, or the oxygen increasing module 4 may be combined with other products that need to be subjected to oxygen increasing control, or the oxygen increasing module 4 may be set as a single general product, and in terms of commerce, when the oxygen increasing module 4 is set as a general product, the product may be completely and independently sold and advertised, and has a wide application range and a high commercial value.

In some embodiments of the present invention, the controller 5, when controlling the operation mode of the oxygen increasing module 4 according to the current operation time point, is configured to determine whether the current operation time point is within a preset time period.

Wherein, the whole day time can be divided into a time period with low oxygen concentration and a time period with high oxygen concentration according to the change of the oxygen concentration in the outdoor air in the day. Specifically, the oxygen concentration in the outdoor air at 14 hours-18 hours is at a higher level, and the oxygen concentration in the outdoor air is lower in the remaining period, based on which the preset period may be set to 14 hours-18 hours.

In some embodiments, if the current operation time point is within a preset time period, the oxygenation module is controlled to operate in a first working mode.

When the air conditioner 10 operates in a preset time period, the oxygen concentration in the outdoor air is at a higher level, and when the oxygen increasing module 4 works in the preset time period, the oxygen enriching rate of the oxygen increasing module 4 should be controlled to be properly reduced, so that the situation that the oxygen concentration in the indoor air is rapidly increased and even exceeds the comfort level of the human body due to the fact that the oxygen increasing module 4 is excessively enriched and oxygen is transmitted to the air outlet of the indoor unit 1 is avoided.

In other embodiments, if the current operation time point is not within the preset time period, the oxygen increasing module is controlled to operate in the second operation mode, wherein the oxygen enrichment rate of the oxygen increasing module in the second operation mode is greater than the oxygen enrichment rate in the first operation mode.

If the current operating time point of the air conditioner 10 is not 14 hours-18 hours, the oxygen concentration in the outdoor air is low, and if the indoor oxygen concentration is low, the oxygen increasing module 4 needs to be controlled to work to increase the indoor oxygen concentration, the oxygen enriching rate of the oxygen increasing module 4 in the working process in the time period needs to be controlled to be properly increased compared with the oxygen enriching rate in the working process in the preset time period, so that the indoor oxygen concentration can be effectively increased to an appropriate oxygen concentration range, and a fresh oxygen-enriched environment is provided for a human body.

When the current operation time point is in the higher preset time period of the oxygen concentration in the outdoor environment, the oxygen increasing module 4 is controlled to operate the first working mode with the lower oxygen enrichment rate, and when the current operation time point is not in the higher preset time period of the oxygen concentration in the outdoor environment, the oxygen increasing module 4 is controlled to operate the second working mode with the higher oxygen enrichment rate, the indoor oxygen concentration can be controlled to be increased, the condition that the indoor oxygen concentration is increased too fast is avoided, the control is more reasonable, and the intelligent control is realized.

In some embodiments of the present invention, the controller 5, when controlling the on-off state of the oxygen increasing module 4 according to the indoor oxygen concentration, is configured to control the oxygen increasing module 4 to start if the indoor oxygen concentration is lower than the first oxygen concentration threshold.

Wherein, the first oxygen concentration threshold value can be set according to the requirement of the oxygen concentration which can ensure the health requirement of the human body. As can be seen from the above embodiments, when the indoor oxygen concentration drops below 19.6%, the human body may feel uncomfortable, and therefore, the first oxygen concentration threshold may be set to be greater than 19.6%, for example, the first oxygen concentration threshold may be set to 19.8% or 20% or 20.2% or 20.4%, for example, the first oxygen concentration threshold may be set to 20%, the indoor oxygen concentration may be set to the first oxygen concentration threshold, and in the case that the indoor oxygen concentration is lower than the first oxygen concentration threshold, the oxygen increasing module 4 may be controlled to be activated to deliver the oxygen enriched in the air flowing through the indoor unit 1 to the air outlet.

In other embodiments, if the indoor oxygen concentration continuously satisfies the preset oxygen concentration threshold condition within the preset time period, the oxygen increasing module 4 is controlled to stop working, wherein the lower limit value of the oxygen concentration of the preset oxygen concentration threshold condition is greater than the first oxygen concentration threshold.

The preset oxygen concentration threshold value can be set according to the requirement of oxygen concentration capable of creating an indoor living environment on the basis of ensuring the requirement of human health. As can be seen from the above embodiments, when the indoor oxygen concentration is 21% to 23.5%, a pleasant feeling is brought to the human body, and based on the above, in order to provide a fresh oxygen-rich environment to the human body, the lower limit of the preset oxygen concentration threshold may be set to an oxygen concentration value that can satisfy the human body nutrition demand and bring a pleasant feeling to the human body, for example, the lower limit of the preset oxygen concentration threshold may be set to 21% or 21.5% or 22% or 22.5%. However, in order to provide a fresh oxygen-rich environment for a human body, based on the above, the upper limit of the preset oxygen concentration threshold may be an oxygen concentration value that can meet the requirement of human body for nutrition and bring pleasure to the human body, and that does not cause human body "drunk oxygen", for example, the upper limit of the preset oxygen concentration threshold may be set to 22% or 22.5% or 23% or 23.5%, and the lower limit and the upper limit of the preset oxygen concentration threshold in the above embodiments are only used as references, and are not limited herein.

Further, the first oxygen concentration threshold is set only for ensuring the health requirement of the human body, and the preset oxygen concentration threshold is set in consideration of the pleasure feeling of the human body, that is, the mental requirement of the human body is satisfied on the basis of ensuring the basic health of the human body, so the lower limit value of the oxygen concentration required for setting the preset oxygen concentration threshold is greater than the first oxygen concentration threshold, for example, the lower limit value of the preset oxygen concentration threshold may be set to 21%, and the upper limit value of the preset oxygen concentration threshold may be set to 23.5%, that is, when the indoor oxygen concentration is increased and stabilized within the range of the preset oxygen concentration threshold, the indoor oxygen concentration is considered to have reached the appropriate concentration.

Furthermore, the indoor oxygen concentration is increased due to the indoor oxygen increasing after the oxygen increasing module 4 is started, but when a large number of people are in the indoor environment, if it is detected that the indoor oxygen concentration just reaches the lower limit value of the preset oxygen concentration threshold value, the oxygen increasing module 4 is controlled to stop working, and the indoor oxygen concentration may be reduced in a short time. Or, when the indoor oxygen distribution is not uniform, if it is detected that the indoor oxygen concentration is within the range of the preset oxygen concentration threshold, the detection may be inaccurate, and at this time, the control of the oxygen increasing module 4 stops working, which may cause the indoor oxygen concentration not to meet the preset oxygen concentration threshold condition actually.

Above circumstances all probably leads to indoor oxygenation effect unsatisfactory and influence health or user experience to and, if indoor oxygen concentration is unstable or detect indoor oxygen concentration inaccurate, then can lead to controller 5 to need frequently to control oxygenation module 4 to open and stop, increase controller 5's control burden, and oxygenation module 4 frequently opens and stops can influence the life-span of oxygenation module 4, lead to the device damage in the oxygenation module 4 easily. Therefore, a preset time period may be set according to the oxygen enrichment rate of the oxygen module 4 or under a laboratory condition, specifically, the preset time period should satisfy that it is detected that the indoor oxygen concentration has reached the lower limit value of the preset oxygen concentration threshold and within the preset time period, the indoor oxygen concentration has stabilized and does not exceed the range of the preset oxygen concentration threshold, for example, the preset time period may be set to 2min, or 3min, or 4min, or 5min, and the like, which may also occur if the preset time period is set to a short time, and if the preset time period is set to a long time period, the indoor oxygen concentration may exceed the range of the preset oxygen concentration threshold, which is not beneficial to human health, and therefore, the preset time period may be set to 3 min. When the indoor oxygen concentration is detected to continuously meet the preset oxygen concentration threshold condition within 3min, the oxygen increasing module 4 is controlled to stop working, so that the indoor oxygen increasing effect can be ensured, and the comfortable living requirement of a human body can be met.

In some embodiments of the present invention, the oxygen increasing module 3 according to the embodiments of the present invention may be described with reference to fig. 3 to 5, wherein fig. 4 is a schematic view of the oxygen increasing module according to one embodiment of the present invention, fig. 5 is a schematic view of the oxygen increasing module according to another embodiment of the present invention, wherein the controller 5 is not shown in fig. 4 and 5, and an arrow in fig. 5 indicates an air flow direction.

As shown in fig. 4, the oxygen increasing module 4 includes a housing 41, an oxygen increasing device 42, an air pumping device 43 and an air pipe 44.

Specifically, as shown in fig. 5, the housing 41 has an oxygen increasing inlet a and an oxygen increasing outlet B. Air in the outdoor environment flows into the oxygenation module 2 through the oxygenation air inlet A and then flows out of the oxygenation air outlet B to enter the outdoor unit 2. As shown in fig. 3, the aeration air inlet a is close to the air inlet on the air inlet side of the outdoor unit 2.

As shown in fig. 5, an oxygen increasing device 42 is disposed in the housing 41 for enriching oxygen flowing through the air. As shown in fig. 3, the casing 41 may be configured to have a shape corresponding to the size and shape of the air inlet of the outdoor unit 2, so that the casing 41 is just disposed at the air inlet, and when the fan of the outdoor unit 2 operates, the air in the outdoor environment can only flow into the outdoor unit 2 from the oxygen increasing air inlet a, which can ensure that the oxygen increasing device 42 can fully contact with the air flowing through, can enrich oxygen therein as much as possible, and ensure the oxygen enriching rate of the oxygen increasing device 42.

As shown in fig. 4 or fig. 5, the air pumping device 43 is disposed in the housing 41, and an air inlet of the air pumping device 43 is connected to the oxygen increasing device 42 for pumping out oxygen enriched in the oxygen increasing device 42 when being activated. Wherein, the air pumping device 43 is connected with the controller 5, and the controller 5 can control the running state of the air pumping device 43 according to the indoor oxygen concentration. For example, the controller 5 determines that indoor oxygen increasing is required according to the indoor oxygen concentration, and sends a control signal to control the pumping device 43 to start so as to pump the oxygen enriched by the oxygen increasing device 42 out and deliver the oxygen to the indoor, or the controller 5 determines that indoor oxygen increasing is not required according to the indoor oxygen concentration, and does not control the pumping device 43 to start or sends a control signal to control the pumping device 43 to stop running.

As shown in fig. 4 or fig. 5, a first end of the air pipe 44 is connected to an air outlet of the air pumping device 43, a second end of the air pipe 44 is connected to the indoor unit 1, when the air pumping device 43 operates, oxygen enriched in the oxygen increasing device 42 is pumped out and is conveyed to an air outlet of the indoor unit 1 through the air pipe 44, and the enriched oxygen is diffused into an indoor environment along with the outlet air of the indoor unit 1 to increase the indoor oxygen concentration.

In some embodiments of the present invention, the oxygen increasing device 2 according to the embodiments of the present invention may be described with reference to fig. 4 to 7, fig. 6 is a block diagram of the oxygen increasing device according to one embodiment of the present invention, and fig. 7 is a schematic view of the oxygen increasing device according to one embodiment of the present invention, wherein the shutter mechanism 422, the shutter P, and the shutter driving unit Q are not shown in fig. 7.

As shown in fig. 6, the oxygen increasing device 42 includes an oxygen-rich membrane group 421 and a baffle mechanism 422.

The oxygen-enriched membrane group 421 is used for enriching oxygen in the air flowing through. The oxygen enrichment module 421 can be composed of N oxygen enrichment membranes, N is equal to or greater than 1, wherein the number of the oxygen enrichment membranes in the oxygen enrichment membrane module 421 can be set according to needs or under laboratory conditions, for example, the value of N can be 1, 3, 4, 5, etc., for example, N can be set equal to 3. When the number of the oxygen-enriched membrane is more, the oxygen-enriched module 421 has a high oxygen-enriched rate, when the number of the oxygen-enriched membrane is less, the oxygen-enriched module 421 has a low oxygen-enriched rate, specifically, when the indoor oxygen content is low, the oxygen-enriched membrane 421 has a low oxygen-enriched rate, the number of the oxygen-enriched membrane is not set to be small, and when the oxygen-enriched module 4 works, when it is detected that the indoor oxygen concentration just reaches the lower limit value of the preset oxygen concentration threshold value and does not exceed the range of the preset oxygen concentration threshold value within the preset time, the number of the oxygen-enriched membrane structures is not set to be large.

More specifically, the oxygen-rich membrane structures may allow oxygen to pass through but not other gas components such as nitrogen, and each oxygen-rich membrane structure is further provided with a certain storage space for storing the enriched oxygen. It can be understood that, when the oxygen increasing module 4 does not work, the oxygen increasing module 421 can also enrich oxygen, that is, as long as there is air flowing through the oxygen increasing module 421, the oxygen increasing module 421 can enrich oxygen. However, since the cavity for storing oxygen in the oxygen enrichment membrane structure is limited, when the oxygen increasing module 4 does not work, the oxygen concentration in the cavity of the oxygen enrichment membrane structure gradually increases along with the time extension, and when the oxygen concentration in the cavity increases to a certain degree, a pressure difference is formed outside the cavity, so that the oxygen enrichment capacity of the oxygen enrichment module 421 can be inhibited to a certain degree.

Furthermore, the pumping rate of the pumping device 43 during operation can be kept unchanged, so that oxygen enriched by the oxygen enriching device 42 can be delivered to the indoor environment in time, and the phenomenon that oxygen enrichment is inhibited due to too high internal pressure of the cavity of the oxygen-enriched membrane structure caused by more high-concentration oxygen in the cavity is prevented.

In some embodiments, the shutter mechanism 422 includes a shutter P and a shutter driving unit Q. The baffle plate P is movably arranged at the oxygen increasing air inlet A and is used for not shielding or partially shielding the oxygen increasing air inlet A. Specifically, when baffle P partially shelters from oxygenation air inlet A, can reduce oxygenation air inlet A's area in other words, and also can shelter from partly oxygen boosting module 421 when sheltering from oxygenation air inlet A to reduce the area of contact of oxygen boosting module 421 and the air that flows through, and then can reduce the speed of oxygen boosting module 421 enrichment oxygen to a certain extent.

In addition, after the contact area between the oxygen enrichment module 421 and the air flowing through is reduced, the usable area of the oxygen enrichment membrane structure can be reduced, and the service life of the oxygen enrichment membrane structure can be prolonged.

And, when the baffle P does not block the oxygen-enriched air inlet a, the oxygen-enriched membrane structure in the oxygen-enriched module 421 can fully contact with the air flowing through, and the oxygen-enriched module 421 has the maximum oxygen-enriched rate. Wherein, the position where the baffle P does not shield the oxygen-increasing air inlet A can be set as the initial position of the baffle P.

The baffle driving unit Q is used for providing acting force for driving the baffle P to move relative to the oxygen increasing air inlet A. Specifically, the barrier driving unit Q is connected to the controller 5 and is operable to provide a driving force in response to a driving signal to drive the barrier P to move.

Specifically, when the controller 5 determines that the oxygen enrichment rate of the oxygen enrichment module 421 needs to be reduced, the driving signal can be sent to the baffle driving unit Q to drive the baffle P to move relative to the oxygen enrichment air inlet a, so as to partially shield the oxygen enrichment air inlet a, thereby reducing the area of the oxygen enrichment air inlet a and reducing the oxygen enrichment rate of the oxygen enrichment module 421.

When the controller 5 determines that the oxygen enrichment module 421 needs to maintain the maximum oxygen enrichment rate, the driving signal can be sent to the baffle driving unit Q to drive the baffle P to move relative to the oxygen enrichment air inlet a until the oxygen enrichment air inlet a is not shielded, so as to increase the area of the oxygen enrichment air inlet a, and the oxygen enrichment membrane structure in the oxygen enrichment module 421 can be in full contact with the air flowing through. Or, when the controller 5 determines that the baffle P is already at the maximum area of the oxygenation air inlet a, the controller does not send a driving signal to the baffle driving unit Q.

In some embodiments of the present invention, the controller 5 is further configured to control the damper driving unit Q to drive the damper P to move to the first position partially blocking the oxygen increasing inlet a when the current operation time point of the compressor is between a preset time period, for example, between 14 hours and 18 hours, so that the oxygen increasing module 4 is in the first operation mode.

The working state of the oxygen increasing module 4 is only influenced by the oxygen concentration in the outdoor air, and the control baffle P is raised to partially shield the oxygen increasing air inlet a and the oxygen increasing air outlet B, mainly to appropriately limit the oxygen enriching rate of the oxygen-enriched membrane group 421 when the oxygen concentration in the outdoor air is high. When the air conditioner 10 is operated in the preset time period, if the indoor oxygen concentration needs to be increased, considering the oxygen enrichment capability of the oxygen enrichment module 4, the oxygen enrichment rate of the oxygen enrichment module 4 needs to be controlled to be properly reduced.

Based on the above, the state of the baffle P when partially shielding the oxygen increasing air inlet A can be set as a first working mode. When the oxygen increasing module 4 is opened and oxygen is enriched in a first working state, the baffle P at the air inlet rises to shield part of the oxygen increasing air inlet A and the oxygen increasing air outlet B, so that the oxygen increasing speed of the oxygen increasing module 4 can be properly reduced, the use of an oxygen-enriched membrane structure is reduced, and the service life of the oxygen-enriched membrane structure is prolonged.

Or, in other embodiments, when the current operating time point is not within the preset time period, the baffle driving unit Q is controlled to drive the baffle P to move to the second position where the oxygen increasing inlet a is not blocked, so that the oxygen increasing module 4 is in the second working state.

When the current operation time point is not in the preset time period, the oxygen concentration in the outdoor air is low, and the oxygen enrichment module 4 needs to be controlled to keep the maximum oxygen enrichment rate considering the oxygen enrichment capacity of the oxygen enrichment module 4. Therefore, the state of the baffle P when the oxygen increasing air inlet A is not shielded can be set to be the second working mode. When the oxygen increasing module 4 enriches oxygen in the second oxygen generating state, the baffle P descends to the initial position, the cross sections of the oxygen increasing air inlet A and the oxygen increasing air outlet at the air inlet are the largest, and the oxygen increasing module 4 enriches oxygen with the highest efficiency.

In some embodiments of the present invention, as shown in fig. 7, the baffle P includes a front baffle P1 and a rear baffle P2, the front baffle P1 is disposed on a side of the oxygen enrichment membrane group 421 close to the oxygen enrichment inlet a, and the rear baffle P2 is disposed on a side of the oxygen enrichment membrane group 421 far away from the oxygen enrichment inlet a.

Preceding baffle P1 and backplate P2 are used for not sheltering from or partly sheltering from oxygenation air inlet A and oxygenation gas outlet B respectively, specifically, can set up the height of preceding baffle P1 and backplate P2 as required to when baffle P1 and backplate P2 sheltered from oxygenation air inlet A and oxygenation gas outlet B before the control, can not shelter from oxygenation air inlet A by a large scale, avoid influencing the holistic operation of air conditioner 10, can effectively adjust the speed of oxygen enrichment membrane group 421 enrichment oxygen again. For example, the heights of the front baffle P1 and the rear baffle P2 can be set to be heights capable of shielding 1/3 oxygen inlet a and oxygen outlet B, so as to effectively adjust the oxygen enrichment rate of the oxygen enrichment membrane group 421.

In other embodiments, the barrier driving unit Q includes a driving lever Q1 and a motor Q2, and the front barrier P1 and the rear barrier P2 are provided on the driving lever Q1. As shown in fig. 7, the driving rod Q1 can be disposed at the bottom of the oxygen-enriched membrane group 421, and the two ends of the driving rod Q1 extend out a certain distance relative to the length direction of the oxygen-enriched membrane group 421, the front baffle P1 and the rear baffle P2 are disposed at the two ends of the driving rod Q1 respectively, the front baffle P1 is just located between the oxygen-enriched air inlet a and the oxygen-enriched membrane group 421, and the rear baffle P2 is just located between the oxygen-enriched air outlet B and the oxygen-enriched membrane group 421 for shielding the oxygen-enriched air inlet a and the oxygen-enriched air outlet B, and the driving rod Q1 drives the front baffle P1 and the rear baffle P2 to move simultaneously when operating, so as to effectively adjust the oxygen-enriched rate of the oxygen-enriched membrane group 421.

Further, the motor Q2 drives the front baffle P1 and the rear baffle P2 to ascend through the driving rod Q1 to a first position partially blocking the oxygen-enriched air inlet a, wherein since the above-mentioned contents have described the scheme of setting the heights of the front baffle P1 and the rear baffle P2, based on the above, since the heights of the front baffle P1 and the rear baffle P2 are limited, the first position can be set to be a position where the front baffle P1 and the rear baffle P2 ascend to the maximum height, even if the front baffle P1 and the rear baffle P2 ascend to the maximum height at this time, the oxygen-enriched air inlet a and the oxygen-enriched air outlet B can be only partially blocked, and the effective adjustment of the oxygen-enriched rate of the oxygen-enriched membrane group 421 can be realized.

Alternatively, the motor Q2 drives the front and rear shutters P1 and P2 to a second position not to block the oxygen-enriched air inlet a through the driving rod Q1. As can be seen from the above embodiment, when the current operation time point is within the preset time period, the controller 5 controls the barrier driving unit Q to drive the barrier P to move to the first position partially blocking the oxygen-enriched air inlet a, and when the preset time period is a time period in which the oxygen concentration in the outdoor air is higher in one day, such as 14 hours-18, the preset time period is shorter than 24 hours in the whole day, that is, in most cases, the barrier P is controlled not to block the oxygen-enriched air inlet a, that is, the barrier P is located at the second position for a long time, so that the second position can be set as the initial position of the barrier P, and frequent starting of the barrier driving unit Q is avoided.

In some implementations of the invention, as shown in fig. 5, the oxygenation module 4 further comprises a first air purification unit 45 and a second air purification unit 46.

The first air purifying unit 45 is disposed at the oxygen-increasing air inlet a of the housing, for example, the first air purifying unit can be disposed inside the housing 41 and completely cover the oxygen-increasing air inlet a for purifying the inlet air. The first air purifying unit 45 may be an air filtering net for filtering the air entering the oxygen increasing module 4, so as to prevent the dust from entering the oxygen increasing device 42 and being adsorbed on the surface of the oxygen-rich membrane structure to affect the oxygen-rich performance thereof.

The second air purifying unit 46 is disposed at the oxygen increasing air outlet B of the housing, for example, may be disposed inside the housing 41 and completely cover the oxygen increasing air outlet B for purifying the discharged air. The second air purifying unit 46 may also be an air filtering net for filtering the air discharged from the oxygen increasing module 4 to prevent dust from entering the outdoor unit 2 or the indoor unit 1, so as to keep the indoor air clean.

In addition, the first air cleaning unit 45 and the second air cleaning unit 46 may be provided in a detachable structure, and may be periodically cleaned and replaced. It can be understood that after the oxygen increasing module 4 is used for a long time, the air filter screen may be blocked, air cannot smoothly enter the oxygen increasing module 4, or the oxygen increasing efficiency of the oxygen increasing module 4 is greatly reduced, so that the air filter screen needs to be cleaned or replaced regularly. For example, a replacement or cleaning cycle of 1 year may be set.

When the technical scheme is adopted, the installed oxygen increasing modules are basically a set of independent devices, corresponding silencing devices need to be configured, the structure is complex, and the oxygen generating precision is difficult to accurately control.

Based on this, in some embodiments, the oxygen increasing module 4 of the present invention is provided with a sound attenuation layer body on the inner side of the housing 41, and the sound attenuation layer body is provided with a concave pit. Specifically, the silencing layer can be made of silencing material, the pits can effectively absorb noise generated during operation of the air pumping device 43 and the like, and the pits are uniformly distributed on other surfaces except the oxygen increasing air inlet A and the oxygen increasing air outlet B inside the shell 41 and used for reducing noise generated during operation of the oxygen increasing module 4.

In some embodiments of the present invention, an oxygen increasing module 4 is further provided, and in particular, the oxygen increasing module 4 according to the embodiments of the present invention may be described with reference to fig. 4 to 7. As shown in fig. 4, the oxygen increasing module 4 includes a housing 41, an oxygen increasing device 42, an air pumping device 43 and an air pipeline 44.

As shown in fig. 5, an oxygen increasing device 42 is disposed in the housing 41 for enriching oxygen flowing through the air. As shown in fig. 3, the casing 41 may be configured to have a shape corresponding to the size and shape of the air inlet of the outdoor unit 2, so that the casing 41 is just disposed at the air inlet, and when the fan of the outdoor unit 2 operates, the air in the outdoor environment can only flow into the outdoor unit 2 from the oxygen increasing air inlet a, which can ensure that the oxygen increasing device 42 can fully contact with the flowing air, can enrich oxygen therein as much as possible, and can ensure the oxygen increasing rate of the oxygen increasing device 42.

As shown in fig. 5, 6 and 7, the oxygen increasing device 42 includes an oxygen-enriched membrane group 421, a baffle P and a baffle driving unit Q.

The baffle plate P is movably arranged at the oxygen increasing air inlet A and is used for not shielding or partially shielding the oxygen increasing air inlet A. Specifically, when baffle P partially shelters from oxygenation air inlet A, can reduce oxygenation air inlet A's area in other words, and also can shelter from partly oxygen boosting module 421 when sheltering from oxygenation air inlet A to reduce the area of contact of oxygen boosting module 421 and the air that flows through, and then can reduce the speed of oxygen boosting module 421 enrichment oxygen to a certain extent.

The baffle driving unit Q is used for providing acting force for driving the baffle P to move relative to the oxygen increasing air inlet A. Specifically, the barrier driving unit Q is connected to the controller 5, and is operable to provide a driving force in response to a driving signal to drive the barrier P to move.

Specifically, when determining that the oxygen enrichment rate of the oxygen enrichment module 421 needs to be reduced, the baffle driving unit Q can move relative to the oxygen inlet a through the driving baffle P to partially shield the oxygen inlet a, so as to reduce the area of the oxygen inlet a and reduce the oxygen enrichment rate of the oxygen enrichment module 421. When confirming that oxygen enrichment module 421 is required to keep the maximum oxygen enrichment rate, baffle drive unit Q can move relative to oxygenation air inlet A through drive baffle P until not sheltering from oxygenation air inlet A, advances the area of increase oxygenation air inlet A, and the oxygen-enriched membrane structure in oxygen enrichment module 421 can fully contact with the air of flowing through.

According to the oxygen increasing module 4 provided by the embodiment of the invention, by arranging the baffle P and the baffle driving unit Q, the baffle driving unit Q can drive the baffle P to not shield or partially shield the oxygen increasing air inlet A so as to adaptively adjust the oxygen increasing rate of the oxygen-enriched membrane group 421, that is, the oxygen increasing module 4 of the embodiment can operate in different working modes based on actual needs, and can realize accurate and efficient oxygen increase for an indoor environment space, thereby creating a comfortable indoor environment for a human body, not affecting the indoor temperature, meeting the health requirements of the human body and ensuring the comfort of the human body.

In some embodiments of the present invention, as shown in fig. 7, the baffle P includes a front baffle P1 and a rear baffle P2, the front baffle P1 is disposed on a side of the oxygen enrichment membrane group 421 close to the oxygen enrichment inlet a, and the rear baffle P2 is disposed on a side of the oxygen enrichment membrane group 421 far from the oxygen enrichment inlet a.

The first air purifying unit 45 is disposed at the oxygen increasing air inlet a of the housing, for example, may be disposed inside the housing 41 and completely cover the oxygen increasing air inlet a for purifying the inlet air. The first air purifying unit 45 may be an air filtering net for filtering the air entering the oxygen increasing module 4, so as to prevent the dust from entering the oxygen increasing device 42 and being adsorbed on the surface of the oxygen-rich membrane structure to affect the oxygen-rich performance thereof.

Based on this, in some embodiments, the oxygen increasing module 4 of the present embodiment is provided with a sound attenuation layer body on the inner side of the housing 41, and the sound attenuation layer body has a concave pit. Specifically, the silencing layer can be made of silencing material, the pits can effectively absorb noise generated during operation of the air pumping device 43 and the like, and the pits are uniformly distributed on other surfaces except the oxygen increasing air inlet A and the oxygen increasing air outlet B inside the shell 41 and used for reducing noise generated during operation of the oxygen increasing module 4.

In some embodiments of the present invention, a control method of an air conditioner is also provided, the control method is used for the air conditioner 10 of the above first aspect embodiment, wherein the air conditioner 10 includes an indoor unit 1 and an outdoor unit 2, and an air inlet side of the outdoor unit 2 is provided with an oxygen increasing module 4 for delivering enriched oxygen to an air outlet of the indoor unit. Specifically, the air conditioner 10 according to the embodiment of the present invention can be understood by referring to fig. 2 and 3 and the related contents, which are not described herein again.

As shown in fig. 8, which is a flowchart illustrating a control method of an air conditioner according to an embodiment of the present invention, the control method of the air conditioner includes steps S1-S3, as follows.

And S1, acquiring indoor oxygen concentration information and acquiring the current operating time point of the air conditioner compressor.

The indoor oxygen concentration detected by the oxygen concentration sensor can be directly obtained, and the indoor oxygen concentration is an important factor influencing the health and the comfort of a user, so that the indoor oxygen concentration can be used as a reference condition to ensure the effect of the oxygen increasing module on enriching oxygen flowing through the air.

The current operating time point may be understood as an operating time point of a day in which the air conditioner is currently operating. It will be appreciated that the oxygen concentration in the outdoor air is constantly changing during the day, for example, the oxygen concentration in the outdoor air at 14 hours-18 hours is at a higher level, and the oxygen concentration in the outdoor air is lower during the rest of the time, and therefore, the current operating time point of the air conditioner can be used as a reference condition when controlling the operating state of the oxygen increasing module, so as to ensure the effect of the oxygen increasing module in enriching the oxygen passing through the air.

And S2, controlling the starting and stopping states of the oxygenation module according to the indoor oxygen concentration information.

It can be understood that the height of the indoor oxygen concentration can be determined according to the indoor oxygen concentration information, wherein when the indoor oxygen concentration is too low, the human health and even the life safety of the human body can be affected, and when the indoor oxygen concentration is too high, the phenomenon of 'drunk oxygen' can be caused to occur. Therefore, when the indoor oxygen concentration is low, the indoor oxygen concentration needs to be increased to meet the requirements of health and comfort of users, after the oxygen increasing module is controlled to be started and operated, the oxygen increasing module enriches oxygen flowing through the air and transmits the enriched oxygen to the air outlet of the indoor unit to increase the indoor oxygen concentration. When the indoor oxygen concentration is in a proper range or the indoor oxygen concentration is higher, the indoor oxygen concentration does not need to be further improved, the oxygen increasing module is controlled not to be started or stopped to operate, the dynamic state of the indoor oxygen concentration is maintained in a proper range, a fresh oxygen-enriched environment is provided for a human body, and the health of a user is facilitated, and the comfort of the user is improved.

And S3, controlling the working mode of the oxygen increasing module according to the current running time point when the oxygen increasing module runs, wherein the oxygen increasing module has different oxygen increasing rates in different working modes.

Specifically, the controlling of the operation mode of the oxygen increasing module may include controlling an oxygen increasing rate when the oxygen increasing module operates. The oxygen enriching module enriches oxygen according to the following principle: when the oxygen increasing module is powered on to work, the oxygen increasing module can separate oxygen in air flowing through and discharge other gas components such as nitrogen in the air from the air outlet side of the outdoor unit. The amount of air flowing into the outdoor unit between the air inlet side units of the outdoor unit is unchanged, and if the oxygen concentration in the outdoor air is always unchanged, the oxygen amount, namely the oxygen increasing rate, in the air flowing through the oxygen increasing module separated in unit time is unchanged when the oxygen increasing module works.

As can be seen from the above embodiments, the oxygen concentration in the outdoor air is different depending on the current operating point at which the air conditioner is operated. Based on this, for the same oxygenation module, if the oxygenation module is powered on to work, and always keeps a working state, if the current operation time point is a time period in which the oxygen concentration in the outdoor air is at a high level in a day, the oxygenation rate of the oxygenation module is higher, and if the current operation time point is a time period in which the oxygen concentration in the outdoor air is at a normal level in a day, the oxygenation rate of the oxygenation module 4 is lower than the oxygen enrichment rate of the oxygenation module when the oxygen concentration in the outdoor air is at a high level. Therefore, in order to control the oxygen increasing module to always keep a stable oxygen enriching efficiency, the working mode of the oxygen increasing module can be controlled according to the previous running time point so as to ensure that the indoor oxygen concentration can be reasonably and stably improved.

According to the control method of the air conditioner provided by the embodiment of the invention, the oxygen increasing module is arranged on the air inlet side, so that the running state of the oxygen increasing module can be controlled in real time according to the indoor oxygen concentration and the current running time point, wherein when the indoor oxygen concentration is low, the controller can control the oxygen increasing module to be started so as to convey oxygen enriched by the oxygen increasing module to the indoor, the indoor oxygen concentration is effectively improved, and when the indoor oxygen concentration is high, the controller can control the oxygen increasing module to stop running, so that the dynamic adjustment of the indoor oxygen concentration is realized. And when the oxygenation module operates, the oxygenation module is controlled to operate different working modes according to the change of atmospheric oxygen content in different outdoor time periods, and by adopting a time-division and multi-mode oxygenation scheme, the indoor environment space can be accurately and efficiently oxygenated, so that a comfortable indoor environment can be created for a human body, the indoor temperature cannot be influenced, the human body health requirement is met, and the comfort level of the human body is guaranteed.

In some embodiments of the present invention, as shown in fig. 9, which is a flowchart illustrating a control method of an air conditioner according to another embodiment of the present invention, wherein the operation mode of the oxygen increasing module is controlled according to the current operation time point, that is, the above step S3 may include steps S31-S33.

And S31, judging whether the current operation time point is in the preset time period.

The oxygen concentration in the outdoor air is in a higher level, and the oxygen concentration in the outdoor air in the rest time period is lower. Specifically, the 14 th-18 time period is set to 14 th-18 th.

And S32, if the current operation time point is in the preset time period, controlling the oxygenation module to operate in the first working mode.

When the air conditioner operates in a preset time period, the oxygen concentration in the outdoor air is at a higher level, and when the oxygen increasing module works in the preset time period, such as 14 hours to 18 hours, the oxygen enriching rate of the oxygen increasing module is controlled to be properly reduced, so that the situation that the oxygen concentration in the indoor air is rapidly increased and even exceeds the comfort degree of a human body due to the fact that the oxygen increasing module is excessively enriched and is transmitted to the air outlet of the indoor machine is avoided.

And S33, if the current operation time point is not in the preset time period, controlling the oxygen increasing module to operate in a second working mode, wherein the oxygen enrichment rate of the oxygen increasing module in the second working mode is greater than the oxygen enrichment rate in the first working mode.

If the current operation time point of the air conditioner is not in a preset time period such as 14 hours to 18 hours, the oxygen concentration in the outdoor air is low, if the indoor oxygen concentration is low, the oxygen increasing module needs to be controlled to work to increase the indoor oxygen concentration, the oxygen enriching rate of the oxygen increasing module in the working process in the time period needs to be controlled to be properly increased compared with the oxygen enriching rate in the working process in the preset time period, so that the indoor oxygen concentration can be effectively increased to an appropriate oxygen concentration range, and a fresh oxygen-enriched environment is provided for a human body.

When the current operation time point is in the higher preset time quantum of oxygen concentration in the outdoor environment, control oxygenation module operation oxygen enrichment rate than lower first mode of operation to and when the current operation time point is not in the higher preset time quantum of oxygen concentration in the outdoor environment, control oxygenation module operation oxygen enrichment rate than higher second mode of operation, can control indoor oxygen concentration and promote, also be so as to cause the too fast condition of indoor oxygen concentration promotion, make control more reasonable, and more intelligent.

In an embodiment of the present invention, as shown in fig. 10, the method for controlling an air conditioner according to another embodiment of the present invention, wherein the start-stop state of the oxygen increasing module is controlled according to the indoor oxygen concentration information, that is, the step S2 specifically includes steps S21 and S22.

And S21, if the indoor oxygen concentration is lower than the first oxygen concentration threshold value, controlling the oxygenation module to start.

Wherein, the first oxygen concentration threshold value can be set according to the requirement of the oxygen concentration which can ensure the health requirement of the human body. As can be seen from the above embodiments, when the indoor oxygen concentration drops below 19.6%, the human body may feel uncomfortable, and therefore, the first oxygen concentration threshold may be set to be greater than 19.6%, for example, the first oxygen concentration threshold may be set to 19.8% or 20% or 20.2% or 20.4%, for example, the first oxygen concentration threshold may be set to 20%, the indoor oxygen concentration may be set to the first oxygen concentration threshold, and in the case that the indoor oxygen concentration is lower than the first oxygen concentration threshold, the oxygen increasing module may be controlled to be activated to deliver the oxygen enriched in the air flowing through the indoor unit to the outlet of the indoor unit.

S22, if the indoor oxygen concentration continuously meets the preset oxygen concentration threshold condition within the preset time, controlling the oxygen increasing module to stop working, wherein the lower limit value of the oxygen concentration of the preset oxygen concentration threshold condition is larger than the first oxygen concentration threshold.

The preset oxygen concentration threshold value can be set according to the requirement of oxygen concentration capable of creating an indoor living environment on the basis of ensuring the requirement of human health. As can be seen from the above embodiments, when the indoor oxygen concentration is 21% to 23.5%, a pleasant feeling is brought to the human body, and based on the above, in order to provide a fresh oxygen-rich environment to the human body, the lower limit of the preset oxygen concentration threshold may be set to an oxygen concentration value that can satisfy the demand of human body for nutrition and bring a pleasant feeling to the human body, for example, the lower limit of the preset oxygen concentration threshold may be set to 21% or 21.5% or 22% or 22.5%. However, in order to provide a fresh oxygen-rich environment for a human body, based on the above, the upper limit of the preset oxygen concentration threshold may be an oxygen concentration value that can meet the requirement of human body for nutrition and bring pleasure to the human body, and that does not cause human body "drunk oxygen", for example, the upper limit of the preset oxygen concentration threshold may be set to 22% or 22.5% or 23% or 23.5%, and the lower limit and the upper limit of the preset oxygen concentration threshold in the above embodiments are only used as references, and are not limited herein.

Furthermore, the indoor oxygen concentration is increased due to the fact that the oxygen increasing module performs indoor oxygen increasing after being started, but when a large number of people exist in the indoor environment, if the fact that the indoor oxygen concentration just reaches the lower limit value of the preset oxygen concentration threshold value is detected, the oxygen increasing module is controlled to stop working, and the indoor oxygen concentration may be reduced in a short time. Or, when the indoor oxygen distribution is not uniform, if it is detected that the indoor oxygen concentration is within the range of the preset oxygen concentration threshold, the detection may be inaccurate, and at this time, the control of the oxygen increasing module stops working, which may cause the indoor oxygen concentration not to meet the preset oxygen concentration threshold condition actually.

Above circumstances all probably leads to the unsatisfactory influence of indoor oxygenation effect and health or user experience to, if indoor oxygen concentration is unstable or detect indoor oxygen concentration inaccurate, then can lead to frequently controlling oxygenation module and opening and stop, increase the control burden, and oxygenation module frequently opens and stops the life-span that can influence the oxygenation module, lead to the device in the oxygenation module to damage easily. Therefore, a preset time period can be set according to the oxygen enrichment rate of the oxygen enrichment module or under laboratory conditions, specifically, the preset time period should meet the condition that the indoor oxygen concentration is detected to just reach the lower limit value of the preset oxygen concentration threshold and within the preset time period, the indoor oxygen concentration is already stable and cannot exceed the range of the preset oxygen concentration threshold, for example, the preset time period can be set to be 2min or 3min or 4min or 5min or the like, if the preset time period is set to be a short time, the above situation can also occur, if the preset time period is set to be a long time, the indoor oxygen concentration may be caused to exceed the range of the preset oxygen concentration threshold, and the human health is not facilitated, so the preset time period can be set to be 3 min. When the indoor oxygen concentration is detected to continuously meet the preset oxygen concentration threshold condition within 3min, the oxygen increasing module is controlled to stop working, so that the indoor oxygen increasing effect can be ensured, and the comfortable living requirement of a human body can be met.

In some embodiments of the present invention, the oxygen enrichment module 4 comprises an oxygen enrichment membrane group 421 and a baffle mechanism 422, wherein the oxygen enrichment membrane group 421 is used for enriching oxygen flowing through the air. The baffle mechanism 422 includes a baffle P and a baffle driving unit Q, wherein the baffle driving unit Q provides an acting force for driving the baffle P to move relative to the oxygen-enriched air inlet a, so that the baffle P does not shield or partially shields the oxygen-enriched air inlet a. Specifically, the oxygen-enriched membrane group 421 and the baffle mechanism 422 according to the embodiment of the present invention can be understood with reference to fig. 4 to fig. 7 and related contents in the above embodiments, which are not described herein again.

In some embodiments, as shown in fig. 11, the method for controlling an air conditioner according to another embodiment of the present invention, wherein the operating mode of the oxygen increasing module is controlled according to the current operating time point, that is, the step S3 may specifically include step S321 or step S331.

S321, when the current operation time point is within a preset time period, controlling the baffle driving unit to drive the baffle to move to a first position partially covering the oxygen increasing air inlet, so that the oxygen increasing module is in a first working mode.

The working state of the oxygen increasing module is only influenced by the oxygen concentration in the outdoor air, and the baffle is controlled to ascend to partially shield the oxygen increasing air inlet and the oxygen increasing air outlet, so that the oxygen enriching speed of the oxygen enriching membrane group is properly limited when the oxygen concentration in the outdoor air is high. And the preset time period is a time period with higher oxygen concentration in outdoor air in a day, such as 14 hours-18 hours, when the air conditioner operates in the preset time period, if the indoor oxygen concentration needs to be increased, the oxygen enrichment capacity of the oxygen enrichment module is considered, and at this time, the oxygen enrichment rate of the oxygen enrichment module needs to be controlled to be properly reduced.

Based on the above, the state of the baffle plate partially blocking the oxygen increasing air inlet can be set as a first working mode. When the oxygenation module is opened and oxygen is enriched in a first working state, the baffle at the air inlet rises to shield part of the oxygenation air inlet and the oxygenation air outlet, so that the oxygen enrichment rate of the oxygenation module can be properly reduced, the use of an oxygen enrichment membrane structure is reduced, and the service life of the oxygen enrichment membrane structure is prolonged.

And S331, when the current operation time point is not in the preset time period, controlling the baffle driving unit to drive the baffle to move to a second position where the oxygen increasing air inlet is not shielded, so that the oxygen increasing module is in a second working state.

When the current running time point is not in the preset time period, the oxygen concentration in the outdoor air is low, and the oxygen increasing module needs to be controlled to keep the maximum oxygen rate enrichment considering the oxygen enriching capacity of the oxygen increasing module. Therefore, the state that the baffle does not shield the oxygen increasing air inlet can be set as the second working mode. When the oxygenation module enriches oxygen in a second oxygen generation state, the baffle falls to the initial position, the cross sections of the oxygenation air inlet and the oxygenation air outlet at the air inlet are the largest, and the oxygen enrichment efficiency of the oxygenation module is the highest.

In some embodiments, as shown in fig. 12, a method for controlling an air conditioner according to another embodiment of the present invention, wherein the method for controlling an air conditioner may include steps S101 to S109, as follows.

And S102, judging whether the indoor oxygen concentration is lower than the first oxygen concentration threshold value, if the judgment result is yes, executing the step S103, and if the judgment result is no, executing the step S104.

And S103, the oxygenation module is not started.

And S104, judging whether the current operation time point is in a preset time period, if so, executing the step S105, and if not, executing the step S106.

S105, the oxygen increasing module operates in a first working mode, wherein when the oxygen increasing module is in the first working mode, the baffle at the air inlet rises to shield part of the oxygen increasing air inlet and the oxygen increasing air outlet, the oxygen enrichment rate of the oxygen increasing module can be properly reduced, the use of an oxygen enrichment membrane structure is reduced, and the service life of the oxygen enrichment membrane structure is prolonged.

S106, the oxygen increasing module operates in a second working mode, wherein when the oxygen increasing module is in the second working mode, the baffle plate descends to the initial position, the cross sections of the oxygen increasing air inlet and the oxygen increasing air outlet at the air inlet are the largest, and the oxygen increasing module has the highest oxygen enriching efficiency.

S107, judging whether the indoor oxygen concentration continuously meets the preset oxygen concentration threshold condition within the preset time length, if the judgment result is yes, executing the step S108, and if the judgment result is no, returning to execute the step S104.

And S108, stopping the oxygen increasing module.

S109, after 5min interval, repeating the steps S101-S108 again.
