Because among the prior art, the air of its place indoor space constantly discharges when indoor exhaust apparatus opens, can form negative pressure state indoor, and exhaust apparatus's exhaust resistance increases under the negative pressure state, leads to indoor dirty air to be difficult to get rid of outdoor, makes the air quality of indoor environment can't effectively improve.

The invention provides the solution, and aims to avoid the occurrence of an indoor negative pressure state when the exhaust equipment is started and effectively improve the indoor air quality.

The embodiment of the invention provides an air treatment device.

Specifically, referring to fig. 1 to 3 and 7 to 9, in the present embodiment, the air processing apparatus includes a casing 100, a fresh air blower 200 disposed in the casing 100, a circulation blower 300, and a heat exchanger 600.

A fresh air duct 110 and a circulating air duct 120 which are mutually independent are formed in the shell 100, a fresh air inlet 101, a circulating air inlet 102 and an indoor air outlet 103 are arranged on the shell 100, wherein the fresh air duct 110 is communicated with the fresh air inlet 101 and the indoor air outlet 103, the circulating air duct 120 is communicated with the circulating air inlet 102 and the indoor air outlet 103, and a circulating air valve 102a is arranged at the circulating air inlet 102.

The fresh air fan 200 is arranged in the fresh air duct 110, the circulating fan 300 is arranged in the circulating air duct 120, and the fresh air duct 110 and the circulating air duct 120 are communicated or separated through the bypass valve 141.

The air treatment device has at least two modes:

in the first mode, the bypass valve 141 is closed, and the fresh air fan 200 drives outdoor fresh air to enter the fresh air duct 110 from the fresh air inlet 101 and flow to the indoor air outlet 103;

in the second mode, the bypass valve 141 is opened, the circulating air valve 102a is closed, and the circulating fan 300 drives fresh outdoor air to enter the circulating air duct 120 from the fresh air inlet 101 and flow to the indoor air outlet 103.

In this embodiment, the fresh air inlet 101 is communicated with an outdoor environment, and the circulating air inlet 102 and the indoor air outlet 103 are communicated with an indoor environment or an indoor air duct. The fresh air duct 110 and the circulating air duct 120 are independent from each other, and the fresh air fan 200 and the circulating fan 300 operate independently from each other. The fresh air duct 110 and the circulating air duct 120 are communicated or separated by the bypass valve 141, and different fresh air introducing paths can be realized by opening and closing the bypass valve 141:

when the bypass valve 141 is closed, the fresh air is introduced by turning on the fresh air fan 200, and the fresh air fan 200 drives outdoor fresh air to flow into the indoor or indoor air duct from the indoor air outlet 103 through the fresh air inlet 101 and the fresh air duct 110 in sequence, which is the first mode. In this mode, the circulating fan 300 in the circulating air duct 120 may be turned on or off, and thus, the introduction of fresh air is not affected. This first mode is applicable to that the indoor air is little negative pressure or middle negative pressure state, for example smoke ventilator is low-grade position operation or when only opening a small amount of air discharge fans, for indoor suitable amount new trend of mending to guarantee indoor outer atmospheric pressure balance.

When the bypass valve 141 is opened, the fresh air duct 110 is communicated with the circulating air duct 120, the circulating air valve 102 is closed, and outdoor fresh air is driven to flow into an indoor or indoor air duct from the indoor air outlet 103 through the fresh air inlet 101 and the circulating air duct 120 only by opening the circulating fan 300, namely, the second mode is the second mode.

Or, under the condition that the bypass valve 141 is opened, the circulating air valve 102 is closed, the fresh air fan 200 and the circulating fan 300 are simultaneously opened, after outdoor fresh air is driven to enter from the fresh air inlet 101, a part of air flow flows to the indoor air outlet 103 from the fresh air duct 110, the other part of air flow flows to the indoor air outlet 103 from the circulating air duct 120, at this time, the fresh air introducing amount is driven by the fresh air fan 200 and the circulating fan 300 together, and the third mode is the third mode of the air processing device, and is suitable for the indoor air to be in a medium negative pressure or high negative pressure state, for example, when a range hood runs in a medium/high position or a large number of exhaust fans are started or the range hood and the exhaust fans run simultaneously, a large amount of fresh air is supplemented indoors, so as to ensure the air pressure balance between the indoor and the outdoor.

It should be noted that, when fresh air is introduced by using the circulating fan 300, the circulating air valve 102a is not necessarily in a closed state, but may also be in an open state, at this time, both the circulating air inlet 102 and the bypass valve 141 are opened, the circulating fan 300 can simultaneously drive indoor air and outdoor fresh air to enter the circulating air duct 120, after the outdoor fresh air and the indoor fresh air are mixed and heat exchanged in the circulating air duct 120, the mixed air is introduced into an indoor environment from the indoor air outlet 103, temperature impact on the indoor air outlet 103 can be reduced, or when a heat exchanger is arranged in the circulating air duct 120, the mixed gas of the outdoor fresh air and the indoor fresh air can reduce temperature impact on the heat exchanger, and the energy saving effect is improved. This kind of mode can be applicable to the less condition of volume demand is mended to the new trend.

When the bypass valve 141 is closed, only the circulating fan 300 can be opened, and the fresh air fan 200 is not opened, which can be used for the situation that the air pressures in different indoor areas are different, if the range hood in the kitchen operates, and the air volume in the living room is large, the air in the living room can flow from the indoor air outlet 103 to the air pipe communicated with the kitchen through the driving action of the circulating fan 300 through the circulating air inlet 102, so that the air flow in the living room with large air volume can be supplemented into the kitchen in a negative pressure state, thereby ensuring the stability of the air pressure in the kitchen according to the air volume distributed among different indoor areas, and improving the working efficiency of the range hood.

It can be understood that the structural form of the bypass valve 141 may be determined according to actual situations, for example, the door structure, the spherical structure, or the needle structure may be a door structure, a spherical structure, or a needle structure, and different adjustment modes are provided for different structural forms, for example, the door structure may be sliding or rotational driving adjustment, for example, the spherical structure may be rotational driving adjustment, for example, the needle structure is sliding driving adjustment, and the like, and the specific adjustment effect is determined according to actual requirements for fresh air flow. The position of the bypass valve 141 can also be determined according to the actual situation, for example, the bypass valve can be disposed on the air inlet side of the circulating fan 300 and/or the fresh air fan 200, or the air outlet side of the circulating fan 300 and/or the fresh air fan 200, or the air inlet side of the circulating fan 300, the air outlet side of the fresh air fan 200, and the like, and the specific position can be determined according to the internal structural layout of the air processing device.

In practical application, functional modules such as a heat exchanger 600, a purification module, a humidification module or a dehumidification module may be disposed in the circulating air duct 120 to realize circulation of air treatment of indoor air itself. When in the second mode or the third mode, the fresh air introduced into the circulating air duct 120 by the circulating fan 400 may be processed by the functional modules and then enter the room, so as to further improve the quality of the indoor air and reduce the impact on the indoor temperature and humidity. Certainly, the functional modules may be disposed in the fresh air duct 110, so that the fresh air outside can be processed in advance in the first mode, in this embodiment, in order to simplify the structure, the purification module 800 and the heat exchanger 600 are disposed at the indoor air outlet 103 communicated with both the circulating air duct 120 and the fresh air duct 130, and in order to further improve the fresh air quality, the filter module 700 is disposed at the fresh air inlet 101, so that the fresh air outside entering the casing 100 can be filtered in any fresh air introducing mode, and the abrasion to the internal structure of the casing 100 and the air quality are reduced.

The fresh air duct 110 and the circulating air duct 120 are communicated or isolated by a bypass valve 141, so that the air processing device has at least two modes of supplementing fresh air into the room: when the bypass valve 141 is closed, fresh air can be supplied to the room only through the fresh air fan 200 and the fresh air duct 110; when the bypass valve 141 is opened, the circulating air valve 102a is closed, and fresh air can be supplied to the room through the circulating fan 300 and the circulating air duct 120. So, when air treatment facilities was using, can adopt the new trend mode of multiple difference benefit according to the demand of difference, if when smoke ventilator or air discharge fan opened, can guarantee indoor outer atmospheric pressure balance to kitchen, bathroom or other indoor regions benefit the wind, improve the room air quality.

In an embodiment of the present invention, referring to fig. 2 to 5, the bypass valve 141 is used to communicate or block the fresh air inlet 101 and the air inlet side of the circulation fan 300.

Optionally, the bypass valve 141 may be a single door body or a double door body rotatably connected to the housing 100, and the communication or blocking effect is realized by the rotation of the door body, and when the bypass valve is a single door body, one side of the single door body is hinged to the housing 100, and the other side is rotated to realize opening and closing; when the double door body is adopted, two opposite sides of the double door body are hinged to the shell 100, and one opposite side can be rotated to be connected with the fresh air inlet 101, so that a channel from the fresh air inlet 101 to the air inlet side of the circulating fan 300 is formed.

When the bypass valve 141 is closed, the fresh air fan 200 drives outdoor fresh air to sequentially flow through the fresh air inlet 101, the fresh air cavity 111 and the fresh air fan 200 and flow out of the indoor air outlet 103; when the bypass valve 141 is opened, the circulating air valve 102a is closed, when the fresh air fan 200 and the circulating fan 300 are both opened, outdoor fresh air enters the fresh air cavity 111 from the fresh air inlet 101 and then is divided into two parts, one part enters the fresh air fan 200 and flows from the fresh air duct 110 to the indoor air outlet 103, and the other part enters the circulating air cavity 121 through the bypass valve 141 and flows from the circulating air duct 120 to the indoor air outlet 103; or, only the circulating fan 300 is turned on, and outdoor fresh air enters the fresh air cavity 111 from the fresh air inlet 101, then enters the circulating air cavity 121, and flows to the indoor air outlet 103 through the circulating air duct 120.

Similarly, the indoor air outlet 104 and the circulating air inlet 102 are both communicated with the indoor environment, and when the air outlet is used, air pipes communicated with different indoor areas can be connected to the air outlet or directly communicated with the indoor environment, the indoor air outlet 104 and the circulating air inlet 102 are arranged on the same side of the shell 100, and only the area on the same side of the shell 100 is occupied to carry out pipe connection operation, the area on other sides of the shell 100 is not required to be occupied, and the occupied space of the whole structure of the air treatment device is reduced.

In order to improve the heat utilization rate, referring to fig. 2 to 10, in an embodiment of the present invention, a total heat exchanger 500 is disposed in the casing 100, and the exhaust air duct 130 and the fresh air duct 110 are intersected and penetrated through the total heat exchanger 500.

In this embodiment, by arranging the total heat exchanger 500, the exhaust air duct 130 and the fresh air duct 110 are arranged in a crossed manner, so that fresh air introduced from the outdoor can exchange heat with air discharged from the indoor in the total heat exchanger 500, heat of the discharged indoor air is recycled, temperature difference between the introduced fresh air and the indoor temperature is reduced, impact of the introduced fresh air on the heat exchanger 600 at the indoor air outlet 103 is reduced, energy loss of the heat exchanger 600 is reduced, and an energy-saving effect is achieved.

The present invention further provides an indoor air conditioning system, which includes an air pressure detecting device and an air processing device, and the specific structure of the air processing device refers to the above embodiments.

Specifically, the air pressure detection device is used for detecting air pressure detection data of the indoor space where the air processing device is located, and one or more air pressure detection devices can be arranged according to actual requirements. Specifically, when there are multiple air pressure detection devices, the air pressure detection devices can be distributed at different positions in the action space of the air treatment device. Specifically, the air pressure detection device can be arranged close to an area provided with exhaust equipment, for example, a range hood is arranged in a kitchen, and the air pressure detection device can be arranged in the kitchen; an exhaust fan is arranged in the toilet, and an air pressure detection device can also be arranged in the toilet.

When the air pressure value detected by the air pressure detection device is a negative pressure value, different negative pressure values correspond to different operation modes of the air treatment device. Specifically, the negative pressure value is defined to include a first negative pressure value or a second negative pressure value, and the first negative pressure value is smaller than the second negative pressure value.

The air treatment device comprises a first mode or a second mode corresponding to the first negative pressure value, and a third mode corresponding to the second negative pressure value:

in the second mode, the bypass valve 141 is opened, the circulating air valve 102a is closed, and the circulating fan 300 drives fresh outdoor air to enter the circulating air duct 120 from the fresh air inlet 101 and flow to the indoor air outlet 103;

in the third mode, the bypass valve 141 is opened, the circulating air valve 102a is closed, and the fresh air fan 200 and the circulating fan 300 simultaneously drive outdoor fresh air to enter from the fresh air inlet 101 and flow to the indoor air outlet 103 through the fresh air duct 110 and the circulating air duct 120;

wherein the air volume of the third mode is greater than the air volume of the first mode/the second mode.

In this embodiment, the air processing device may select a corresponding mode according to air pressure conditions in different indoor areas or in the whole indoor area, and specifically, a negative pressure device for detecting indoor air pressure may be provided indoors and may be adjusted according to a detection result of the negative pressure device. Alternatively, the negative pressure device may be an air pressure sensor.

It can be understood that the pressure conditions in different indoor areas can be different, for example, the air tightness in a living room or a bedroom is better, an exhaust fan is usually arranged in the bathroom for exhausting air, the smoke exhaust ventilator in a kitchen can exhaust smoke when in operation, or when doors among the living room, the bedroom and the bathroom are opened, the air in the living room and the bedroom can also be influenced by the effect of the exhaust fan of the bathroom, so that the difference of the gas pressure in the areas is influenced, or other exhaust devices are further arranged. Therefore, in the embodiment, the negative pressure device is arranged in the room to detect the air pressure, the negative pressure device can be arranged in each area, or one negative pressure device can be arranged in the whole indoor space, and the mode of the air treatment device is correspondingly adjusted by detecting the air pressure in the room.

In practical application, if when an exhaust fan of an indoor toilet is turned on, the exhaust air volume is small, and the indoor air pressure result detected by the negative pressure device is a first negative pressure value, in this case, the pressure state of the indoor air may be a micro negative pressure state, the air treatment device may be operated in a first mode or a second mode, so that only the fresh air fan 200 or the circulating fan 300 is used for performing a small amount of air supplement to the indoor air, the indoor air volume may be increased appropriately, and the exhaust effect of the exhaust fan is better.

If when having a plurality of bathrooms indoor, when a plurality of air discharge fans open simultaneously, the volume of airing exhaust is great, the indoor atmospheric pressure result that negative pressure device detected out is second negative pressure value, under this condition, the pressure state of room air probably is well negative pressure or high negative pressure state, then can be according to the operation of third mode with air treatment device, carry out a large amount of air supplys the wind to indoor through new trend fan 200 and circulating fan 300 simultaneously, guarantee indoor outer atmospheric pressure balance, make the ventilation effect of air discharge fan better, improve the room air quality.

According to the technical scheme, in the indoor air conditioning system, the indoor air pressure condition is detected through the negative pressure device, and the air treatment device is enabled to operate according to a corresponding mode according to the detected first negative pressure value or second negative pressure value so as to supplement air to the indoor, so that the effects of ensuring indoor and outdoor air pressure balance, ensuring ventilation effect and improving indoor air quality are achieved.

In an embodiment of the indoor air conditioning system, the air conditioning system further comprises a power detection device. The power detection device is connected with the exhaust equipment. The power detection device is used for detecting a power parameter of the exhaust equipment.

In the present embodiment, the power detection device is a current detection device. In other embodiments, the power detection device may also be a device that directly detects power, such as a universal meter. The current detection means may characterize the magnitude of the operating power of the exhaust apparatus by detecting the operating current of the exhaust apparatus.

Specifically, the detected current values of the current detection devices are different, and the corresponding operation modes of the air treatment devices are different if the operation powers of the characterized exhaust devices are different.

The detection result of the current detection device at least comprises a first current value and a second current value, and the first current value is smaller than the second current value;

the air treatment device includes a first mode or a second mode corresponding to the first electric current value, and a third mode corresponding to the second electric current value:

in the second mode, the bypass valve 141 is opened, the circulating air valve 102a is closed, and the circulating fan 300 drives outdoor fresh air to enter the circulating air duct 120 from the fresh air inlet 101 and flow to the indoor air outlet 103;

in the third mode, the bypass valve 141 is opened, the circulating air valve 101a is closed, and the fresh air fan 200 and the circulating fan 300 simultaneously drive outdoor fresh air to enter from the fresh air inlet 101 and flow to the indoor air outlet 103 through the fresh air duct 110 and the circulating air duct 120;

In this embodiment, the air processing device may select a corresponding mode according to an operation condition of the range hood in the indoor kitchen, and specifically, may adjust according to a detection result of the current detection device of the range hood.

It can be understood that the working state of the range hood can be determined according to the actual cooking condition of a user in a kitchen, for example, when cooking or cooking porridge or boiling water, the generated smoke is less, at the moment, the range hood can not be opened or a low gear is opened, the exhaust fan in the range hood runs at a lower rotating speed, the detection result represented on the current detection device is a first current value, under the condition, the pressure state of air in the kitchen can be balanced with outdoor air pressure or is in a micro-negative pressure state, the air treatment device can run according to a first mode or a second mode by only utilizing the fresh air fan 200 or the circulating fan 300 to supplement a small amount of air to the interior of the kitchen, the air quantity in the kitchen can be properly increased, and the air extraction effect of the range hood is better.

If when the cooking modes such as stir-frying, frying and the like are carried out in a kitchen, the generated smoke is large, the range hood can be opened to a middle/high gear at the moment, the exhaust fan in the range hood runs at a middle/high speed, and the detection structure represented on the current detection device is a second current value, in this case, as the range hood needs to run at a middle/high speed continuously, the range hood can have a large exhaust amount, the air pressure state in the kitchen can be easily formed into a middle negative pressure state or a high negative pressure state, at the moment, in order to ensure the suction effect of the range hood, the air treatment device runs according to a third mode, meanwhile, a large amount of air supplement is carried out on the interior of the kitchen through the fresh air fan 200 and the circulating fan 300, the balance of the air pressure inside and outside the kitchen is ensured, the smoke exhaust effect of the range hood is ensured, and the air quality of the kitchen is further improved.

In the indoor air conditioning system adopting the technical scheme, the current value of the range hood during operation is detected by the current detection device, and the air treatment device is operated according to a corresponding mode to supplement air in the kitchen according to the detected first current value or second current value, so that the effects of ensuring the balance of air pressure inside and outside the kitchen, ensuring the smoke exhaust effect of the range hood and improving the air quality in the kitchen are achieved.

Further, in the embodiment of the present invention, the air processing apparatus further includes a controller, and the exhaust fan, the fresh air fan, the circulation fan, the bypass valve, the circulation air valve, the air pressure detection device, the power detection device, and the like are all connected to the controller.

Specifically, the controller includes: a processor 1001 (e.g., CPU), memory 1002, etc. The above components are connected through wired or wireless communication. The memory 1002 may be a high-speed RAM memory or a non-volatile memory (e.g., a disk memory). The memory 1002 may alternatively be a storage device separate from the processor 1001.

The memory 1002, which is a kind of computer-readable storage medium, may include a computer program therein. In the controller, the processor 1001 may be configured to call a computer program stored in the memory 1002 and perform operations of the relevant steps of the indoor air conditioning method in the following embodiments.

The embodiment of the invention also provides an indoor air conditioning method which is applied to control the air treatment device.

Referring to fig. 11, an embodiment of an indoor air conditioning method according to the present application is provided. In this embodiment, the indoor air conditioning method includes:

step S10, acquiring air pressure detection data in the indoor space where the air processing device is located;

the air pressure detection data is parameters detected by an air pressure detection device in the indoor space where the air processing device is located. The acquired air pressure detection data may be an air pressure value, an indoor and outdoor pressure difference value, or the like. The obtained air pressure detection data can be one or more than one according to actual conditions. In order to make the air treatment device timely supplement air when the indoor space is at negative pressure, the air pressure detection data may include air pressure detection data of a position where the exhaust equipment is located (i.e., a distance from the exhaust equipment is less than a set distance).

The indoor space in which the air treatment device is located refers specifically to a limited space area in which the air treatment device is installed and which can be covered by the air conditioning action of the air treatment device.

The indoor space may be a large space (e.g., a space occupied by a kitchen area) which is completely opened, or a large space (e.g., a space formed by a connected kitchen area, a toilet area, and a living room area) which is formed by connecting a plurality of small partitioned spaces.

Step S20, when the air pressure detection data comprises negative pressure data, controlling the air treatment device to operate in a first mode, a second mode or a third mode; the negative pressure data is air pressure data of which the indoor air pressure is smaller than the outdoor air pressure;

in the first mode, the bypass valve is closed, the fresh air fan is opened, and outdoor fresh air is sent into the indoor space through the fresh air duct; in the second mode, the bypass valve is opened, the circulating fan is opened, and outdoor fresh air is delivered into the indoor space through the circulating air duct; in the third mode, the bypass valve is opened, the circulating fan is opened, the fresh air fan is opened, and outdoor fresh air is sent into the indoor space through the circulating air duct and the fresh air duct.

Specifically, when the air pressure detection data includes an indoor air pressure value, a preset outdoor air pressure value (such as standard atmospheric pressure) can be detected or acquired in real time, the indoor air pressure value and the outdoor air pressure value are compared, and if an indoor air pressure value smaller than the outdoor air pressure value exists, the air pressure detection data can be considered to include negative pressure data; if there is no indoor air pressure value smaller than the outdoor air pressure value, it is determined that the air pressure detection data does not include the negative pressure data. In addition, when the air pressure detection data includes a differential pressure value, the differential pressure is smaller than 0 when it is defined that the indoor air pressure is smaller than the outdoor air pressure, and when the air pressure detection data includes a differential pressure value smaller than 0, the air pressure detection data can be considered to include negative pressure data; otherwise, the air pressure detection data may be considered to not include negative pressure data.

Specifically, one of a first mode, a second mode and a third mode may be preset as a preset mode, and when the air pressure detection data includes negative pressure data, the air pressure detection data directly operates according to the preset mode; in addition, a target mode required by the current air treatment device to operate can be selected from the first mode, the second mode and the third mode based on the actual condition of the indoor space (such as the operating parameters (such as operating power, operating current, fan rotating speed and the like), indoor quality conditions (such as oil smoke concentration and the like) and/or air pressure detection data and the like) of exhaust equipment such as a range hood and the like, and the air treatment device can be controlled to operate in the target mode.

The operation rotating speed of the circulating fan and/or the fresh air fan when the circulating fan and/or the fresh air fan is started can be preset, and can also be determined based on the actual condition of an indoor space, for example, the rotating speed can be determined based on the actually detected parameters of the exhaust equipment such as a range hood and the like (such as operation power, operation current, fan rotating speed and the like, indoor quality conditions (such as oil smoke concentration and the like) and/or air pressure detection data and the like.

The air treatment device is used for supplying fresh air in a first mode, a second mode or a third mode, and the circulating air valve arranged at the air inlet of the circulating air duct can be opened or closed according to actual requirements.

Further, because the smoke exhaust effect influenced by negative pressure is easy to occur when the range hood in the indoor space with good tightness is opened, based on this, the indoor air conditioning method in the embodiment can be applied to the indoor space with good tightness. Before step S10, the tightness of the operating space of the air handling device may be identified, which may be obtained by analyzing the opening and closing conditions of the blocking pieces of the indoor and outdoor openings, such as doors and windows, input by the user, for example, when all doors and windows are closed, the tightness of the operating space may be considered to be good, and step S10 may be executed. In addition, the fresh air fan and/or the circulating fan of the air processing device may be controlled to operate at a set rotation speed, and the air pressure change rate of the indoor environment may be detected, and if the air pressure change rate is greater than the set threshold, it may be determined that the air flow between the space where the air processing device operates and the space outside the space where the air processing device operates is very small and the space is sealed well, then step S10 may be performed. Therefore, the indoor negative pressure state is avoided in the indoor space with better tightness, and the indoor environment quality when the exhaust equipment is opened is ensured.

Further, in the present embodiment, when the air treatment device operates in the first mode or the third mode, the circulation damper is controlled to decrease the opening degree. Specifically, the opening degree may be reduced to be smaller than the set threshold, the circulating air valve may be directly closed, or the opening degree may be reduced by a certain amount at the current opening degree. Whether the circulating air valve is opened or closed can be determined based on the current oil smoke concentration of the indoor space and the indoor and outdoor temperature difference, for example, the circulating air valve can be controlled to be opened when the oil smoke concentration is smaller than a set threshold value and the indoor and outdoor temperature is smaller than a set temperature; otherwise, the circulating air valve can be controlled to be closed.

The reduction of the opening of the circulating air valve reduces dirty air such as oil smoke and the like to participate in internal circulation, so that the dirty air such as the oil smoke and the like can be quickly exhausted outdoors by starting an exhaust fan or exhaust equipment such as a smoke exhaust ventilator and the like, and the interior of the air treatment device is prevented from being polluted; in addition, the air entering the circulating air duct is reduced, so that the indoor heat exchanger has enough heat exchange capacity to exchange heat with fresh air, and meanwhile, the fresh air quantity pumped in when the circulating fan operates is also enabled, so that the heat comfort of the indoor environment is ensured while the indoor environment is prevented from negative pressure by ensuring enough fresh air quantity to supplement air indoors.

Specifically, in this embodiment, the step of controlling the air treatment device to operate in the first mode, the second mode or the third mode includes:

step S21, in the first mode, the second mode, and the third mode, determining that the mode corresponding to the negative pressure data is a target mode; the different negative pressure data correspond to different target modes;

the target mode is one of a first mode, a second mode, and a third mode. And the fresh air volume corresponding to the first mode and the fresh air volume corresponding to the second mode are smaller than the fresh air volume corresponding to the third mode. Based on this, a target fresh air volume may be determined from the negative pressure data, and one of the first mode, the second mode, and the third mode may be determined as the target mode from the target fresh air volume.

Specifically, different target modes may be associated with different sizes and quantities of the negative pressure data and/or different detection positions corresponding to the negative pressure data. The larger the indoor and outdoor pressure difference or the larger the indoor negative pressure area corresponding to the negative pressure data is, the larger the fresh air volume corresponding to the corresponding target mode is.

In one embodiment, the negative pressure data is a pressure value, and the target mode is different when the pressure value is different. Specifically, two air pressure intervals may be divided in advance: the target mode corresponding to the first air pressure interval is a first mode or a second mode, and the target mode corresponding to the second air pressure interval is a third mode. Based on this, the air pressure interval in which the air pressure value is located can be determined, and the current target mode can be determined. For example, in a space where the air processing device acts, a kitchen is provided with a range hood, and a washroom is provided with an exhaust fan, when one of the range hood and the exhaust fan is opened, the indoor and outdoor pressure difference is small, the negative pressure data is a first air pressure value, and the first air pressure value is located in the first air pressure interval, the first mode or the second mode is taken as a target mode; when the range hood and the exhaust fan are both opened, the indoor and outdoor pressure difference is large, the negative pressure data is a second air pressure value, the second air pressure value is located in a second air pressure interval, and the third mode is used as the target mode.

In another embodiment, the air pressure detection data includes at least two air pressure values detected at different positions in the indoor space where the air processing device is located, the negative pressure data is the air pressure value smaller than the outdoor air pressure, and the step S21 includes:

step S211, acquiring the quantity of the negative pressure data and the corresponding detection position;

specifically, more than one air pressure detection device can be arranged in the indoor space, and each air pressure detection device correspondingly acquires an air pressure value. The number of the negative pressure data specifically refers to the total number of the collected air pressure values smaller than the outdoor air pressure.

For example, in the indoor space where the air processing device is located, one air pressure detection device may be disposed in a kitchen where the range hood is disposed, and the other air pressure detection device may be disposed in a toilet where the exhaust fan is disposed. Based on this, the position where the air pressure detection device corresponding to each air pressure value in the negative pressure data is located can be determined as the detection position here. Note that the number of negative pressure data is the same as the number of acquired detection positions.

Step S212, determining one of the first mode, the second mode and the third mode as a target mode according to the number and the detection position.

Different numbers and different detection positions may correspond to different target patterns.

Specifically, in this embodiment, when the number is greater than or equal to a preset threshold, it is determined that the third mode is the target mode; when the number is smaller than the preset threshold value, determining the distance between the detection position and the air treatment device, and determining one of the first mode and the second mode as the target mode according to the distance. It should be noted that, in other embodiments, when the number is smaller than the preset threshold, one of the first mode and the second mode may be selected as the target mode randomly or according to a preset mode.

The preset threshold value can be set according to actual conditions. Here, the larger the number is, the larger the air output amount corresponding to the target pattern is, and in the case where the number is the same, different distances correspond to different target air output patterns. The more negative pressure data, the more serious the indoor negative pressure condition, based on the situation, the air treatment device adopts the mode of larger fresh air volume to supplement air, so that the indoor and outdoor air pressure balance can be further effectively maintained, even the indoor can be in a micro-positive pressure state, and the indoor environment quality can be effectively improved.

Further, in this embodiment, in an open state of the exhaust fan, when the distance is greater than or equal to a set distance threshold, it is determined that the first mode is the target mode; when the distance is smaller than the set distance threshold, determining that the second mode is the target mode. When the exhaust fan is started, the indoor air exhausted from the exhaust air duct can exchange heat with the indoor air entering from the fresh air duct in the total heat exchanger. Here, when the number is the same, the longer the distance is, the higher the outlet air temperature corresponding to the target mode is. Specifically, when the exhaust fan is started, the fresh air in the second mode can be subjected to primary heat exchange by the total heat exchanger and then further subjected to further heat exchange by the indoor heat exchanger in the fresh air duct and then sent into the room, and the temperature of the fresh air entering the indoor space from the fresh air duct is higher than that of the fresh air entering the indoor space from the circulating air duct. Based on the above, when the detection position is far away from the air treatment equipment, the air carrying the heat exchange quantity blown out by the air treatment equipment is not easy to blow out of a room due to the operation of the exhaust equipment, and based on the air, the indoor space can be fed with fresh air with relatively low temperature to maintain the stability of the indoor temperature, so that the indoor environment quality can be ensured to be in a better state; and when the detection position is closer to the air treatment equipment, it shows that the air with the heat exchange amount blown out by the air treatment equipment is easier to blow out outdoors due to the operation of the exhaust equipment, and based on the air, the fresh air with higher temperature sent into the indoor space is favorable for maintaining the stability of the indoor temperature, so that the quality of the indoor environment is further improved

In addition, in other embodiments, different mode selection parameters correspond to different target modes, and based on this, the number and the distance may also be weighted and averaged according to a preset weight value to obtain a mode selection parameter, and a mode corresponding to the mode selection parameter is determined as the target mode.

And step S22, controlling the air treatment device to operate the target mode.

In this embodiment, select air treatment device's tonifying wind mode from first mode, second mode and third mode based on negative pressure data to guarantee to send into the accurate nature of the fresh air volume of indoor environment, ensure that indoor environment is under air treatment device's tonifying wind effect, indoor environment can be in the pressure-fired or with the state of outdoor atmospheric pressure equilibrium, guarantee that indoor dirty air can discharge outdoor when exhaust apparatus opens in the indoor space fast, guarantee indoor environment quality.

Further, based on the above embodiment, another embodiment of the indoor air conditioning method of the present application is also provided, and in this embodiment, the air processing device is further provided with an exhaust air duct and an exhaust fan in the exhaust air duct. In the indoor space where the air treatment device is located, besides the air treatment device, exhaust equipment such as a range hood, an exhaust fan and the like can be arranged according to actual requirements, and the exhaust equipment is equipment outside the air treatment device. The exhaust equipment can be arranged in the same area or different areas in the space according to actual requirements. For example, a kitchen is provided with a range hood, and a dining room communicated with the kitchen is provided with an air treatment device; for another example, the range hood and the air treatment device are arranged in a kitchen, and the exhaust fan is arranged in a washroom directly or indirectly communicated with the kitchen. Based on this, referring to fig. 12, before step S10, the method further includes:

step S01, detecting a state parameter of an exhaust apparatus in the indoor space; the exhaust equipment is equipment outside the air treatment device;

the state parameter specifically refers to a characteristic parameter for representing the starting and stopping of the smoke extractor. The state parameter may be detected by the power detection module. Specifically, when the detected power parameter (e.g., current value) is greater than a set threshold, the exhaust device may be considered to be turned on; when the detected power parameter (e.g., current value) is less than or equal to the set threshold, the exhaust may be deemed closed.

And step S02, when the state parameter is in an open state, controlling the exhaust fan to open, and executing the step of acquiring the air pressure detection data in the indoor space where the air processing device is located.

When the exhaust fan is started, indoor dirty air can be sent out of the room through the exhaust air duct of the air treatment device.

The operation rotation speed of the exhaust fan when being started can be a preset rotation speed, and can also be a rotation speed determined according to indoor actual conditions (such as indoor and outdoor current pressure difference, operation parameters of exhaust equipment (such as operation current and operation power), and indoor air quality parameters (such as concentration of dirty air such as oil smoke).

In this embodiment, the opening of the air exhaust fan can enable the indoor processing equipment and the exhaust equipment to exhaust in a matched mode, the air displacement is increased when the indoor air exhaust requirement is met, the outdoor efficiency of indoor foul air exhaust is accelerated, and therefore the indoor environment quality is effectively improved when the exhaust equipment operates.

Further, in this embodiment, the exhaust apparatus includes a range hood, and referring to fig. 13, the step S20 includes:

step S201, in the first mode, the second mode or the third mode, obtaining a first exhaust volume of the range hood and a second exhaust volume of the exhaust fan; the first exhaust volume is determined according to the power parameter of the range hood;

the selection of the target mode of operation of the air treatment device in the first mode, the second mode and the third mode may specifically refer to the manner mentioned in the above embodiments.

The power parameter is specifically a characteristic parameter representing the power of the range hood, and may be a detected operating current value of the range hood or a detected power value of the range hood, and the like.

The first exhaust amount is obtained as follows: acquiring a power parameter of the range hood; and determining the first exhaust amount according to the power parameter. The power parameter is specifically a characteristic parameter representing the power of the range hood, and may be a detected operating current value of the range hood or a detected power value of the range hood, and the like. The larger the power parameter is, the larger the exhaust quantity of the range hood is. The corresponding relationship between the power parameter and the first displacement may be preset, and may be a calculation relationship, a mapping relationship, or the like. And determining the exhaust gas volume corresponding to the currently acquired power parameter as a first exhaust gas volume based on the corresponding relation. Here, the exhaust volume of the range hood is evaluated through the power parameter of the range hood, so that the accuracy of the obtained exhaust volume of the range hood is ensured. It should be noted that, in other embodiments, when the state parameter is in an on state, all fans in the air processing apparatus may be controlled to stop operating, and then, the air pressure change parameter (such as an air pressure change amount, an air pressure change rate, an air pressure change curve, and the like) of the indoor environment is detected, and the first exhaust amount is determined based on the detected air pressure change parameter.

The second displacement can be obtained by obtaining the operation rotating speed of the exhaust fan and analyzing, and the larger the rotating speed of the exhaust fan is, the larger the second displacement is. For example, if the operating speed of the exhaust fan is N, the exhaust air volume P ═ a × N, where a is a preset constant.

Step S202, determining a target rotating speed of a target fan according to the first air displacement and the second air displacement; the target fan is a fan for introducing outdoor fresh air into the air processing device in the current operation mode;

specifically, the target fan in the first mode is a fresh air fan; the target fan in the second mode is a circulating fan; the target fans in the third mode are a circulating fan and a fresh air fan. When the target fan comprises the circulating fan and the fresh air fan, the target rotating speed may specifically comprise target sub-rotating speeds respectively corresponding to the two fans, specifically, both the two target sub-rotating speeds may be determined by the first air displacement and the second air displacement, or the target sub-rotating speed may be the current rotating speed of the target fan corresponding to the target sub-rotating speed, and the other target sub-rotating speed is determined according to the previous target sub-rotating speed, the first air displacement and the second air displacement.

The different first air displacement and the second air displacement correspond to different target rotating speeds of the target fan.

Specifically, in the present embodiment, the total amount of exhaust gas of the indoor space can be calculated from the first amount of exhaust gas and the second amount of exhaust gas: the first displacement + the second displacement is the total displacement. The target rotation speed here is determined based on the total exhaust gas amount. Through the collection and analysis of a large amount of data, the corresponding relation between the rotating speed of the target fan and the corresponding air output quantity can be established in advance. Specifically, the determined total displacement may be used as an air output corresponding to the circulation fan, or a sum of the determined total displacement and a set displacement may be used as an air output corresponding to the circulation fan, and the obtained air output may be substituted into the corresponding relationship to obtain a result as the target rotation speed of the target fan. When the target rotating speed comprises the sub-target rotating speeds corresponding to the circulating fan and the fresh air fan respectively, the total rotating speeds of the two fans can be determined based on the corresponding relation, and then a preset ratio or a ratio obtained based on parameters such as the opening degree of a circulating air valve or indoor temperature is further obtained to distribute the total rotating speeds to obtain the sub-target rotating speeds corresponding to the two fans respectively.

Further, the correspondence relationship may be obtained based on the current state of the circulating damper. The rotating speed and the air output have different corresponding relations when the return air valve is closed and opened, and the rotating speed and the air output have different corresponding relations when the return air valve is opened at different opening degrees. Based on the current opening degree of the return air valve, the corresponding relation is obtained based on the opening degree. The target rotation speed corresponding to the total exhaust gas amount is determined based on the acquired correspondence relationship.

And S203, controlling the target fan to operate according to the target rotating speed.

In this embodiment, combine first displacement and second displacement to confirm the rotational speed of the fan that draws the new trend in the air treatment device, can guarantee through the regulation of fan rotational speed in the air treatment device when smoke ventilator opens, can guarantee that the interior space has sufficient volume of advancing the phoenix to make the space be in constant voltage or pressure-fired state, make smoke ventilator and exhaust fan's cooperation can be fast with indoor oil smoke take out outdoors, improve smoke exhaust effect, guarantee indoor environmental quality. The exhaust volume of the range hood is acquired by combining with the power parameters of the range hood, the accuracy of the determined total exhaust volume is favorably ensured, the rotating speed of the target fan determined based on the total exhaust volume can be further ensured to enable the indoor space to be in a constant-pressure or micro-positive-pressure state, and the effect of quickly exhausting dirty air such as indoor oil smoke out of the room is further improved.

In addition, in other embodiments, when the fresh air fan and the circulating fan are started simultaneously, the fresh air fan can be operated at a fixed rotating speed when started and can also be operated at a variable rotating speed. The operation rotating speed of the fresh air fan can be a preset rotating speed or a rotating speed determined based on actually detected parameters of the range hood (such as operation power, operation current, fan rotating speed and the like), indoor oil smoke concentration, exhaust fan rotating speed and the like. Specifically, in this embodiment, a first rotation speed of the exhaust fan is obtained, and an indoor environment temperature and a set comfortable temperature are obtained; determining a temperature deviation of the indoor ambient temperature from the set comfort temperature; determining the rotation speed ratio of the exhaust fan and the fresh air fan according to the temperature deviation; according to the rotation speed ratio, the first rotation speed and the second rotation speed of the fresh air fan; the second rotational speed is less than the first rotational speed; and controlling the fresh air fan to operate at the second rotating speed. The temperature deviation specifically refers to an absolute value of a difference between two temperatures.
