[0002] As people's living standards improve, the use of air conditioners has become increasingly widespread. People's requirements for air conditioners are no longer limited to temperature control; they also have certain requirements regarding indoor air quality.

[0042] In this application, the term "exemplary" is used to mean "serving as an example, illustration, or description." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to make and use the invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the invention can be made without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0043] This application provides an exhaust device, an air conditioning fresh air control method, an apparatus, an air conditioner, and a storage medium, which will be described in detail below.

[0044] like Figure 1 As shown, Figure 1 This is a schematic diagram of an embodiment of the exhaust device in this application. The exhaust device includes: an exhaust body 1, with a buoyancy channel 10 inside; one end of the buoyancy channel 10 is provided with an outdoor air inlet 100 for communicating with the outdoor airflow, and the other end of the buoyancy channel 10 is provided with an indoor air inlet 101 for communicating with the indoor airflow; a first air pressure buoyancy member 11 is provided inside the buoyancy channel 10, the first air pressure buoyancy member 11 slides inside the buoyancy channel 10, and an exhaust channel 110 is provided inside the first air pressure buoyancy member 11; when the first air pressure buoyancy member 11 is in a first position, one end of the exhaust channel 110 is connected to the outdoor airflow, and the other end of the exhaust channel 110 is connected to the indoor airflow.

[0045] The shape and material of the exhaust body 1 are not specifically limited in this application. It is understood that the exhaust body 1 can be square, irregular in shape, etc., and the material can be rubber, stainless steel, etc.

[0046] The buoyancy channel 10 can be a straight channel, a curved channel, etc., and this application does not make specific limitations. The buoyancy channel 10 is located inside the exhaust body 1, and the two ends of the buoyancy channel 10 are respectively connected to the outside of the exhaust body 1, forming an outdoor air inlet 100 for communicating with the outdoor airflow and an indoor air inlet 101 for communicating with the indoor airflow. That is, one end of the buoyancy channel 10 is connected to the indoor airflow, and the other end of the buoyancy channel 10 is connected to the outdoor airflow.

[0047] It is understood that in some embodiments of this application, when the exhaust device is installed, the indoor air vent 101 can be directly located indoors to achieve communication with the indoor air, and the outdoor air vent 100 can be directly located outdoors to achieve communication with the outdoor air; in other embodiments of this application, the indoor air vent 101 and / or the outdoor air vent 100 can also be connected to the air duct connecting the indoors and / or the air duct connecting the outdoors, thereby achieving communication between the outdoor air vent 100 and the outdoor airflow, and between the indoor air vent 101 and the indoor airflow. The specific airflow communication method is not specifically limited in this application.

[0048] The first buoyancy component is disposed within the buoyancy channel 10 and is slidably connected to the inner wall of the buoyancy channel 10. It can be understood that the shape of the first buoyancy component corresponds to the cross-sectional shape of the buoyancy channel 10. That is, the first buoyancy component is embedded within the buoyancy channel 10 and slides back and forth within the buoyancy channel 10 to ensure the airtightness of the first buoyancy component, preventing the air (indoor air and outdoor air) on both sides of the first buoyancy component from communicating and affecting the pressure difference sensing effect of the first buoyancy component. Furthermore, it can be understood that the first buoyancy component can be made of foam, lightweight stainless steel, etc., to enhance the sensing capability of the first buoyancy component based on indoor and outdoor pressure differences and to prevent the weight of the first buoyancy component from affecting the sensing of indoor and outdoor pressure differences.

[0049] It is understood that in some embodiments of this application, an airtight sliding member, such as a sliding bearing with good airtightness, may be provided on the peripheral wall where the first buoyancy member connects to the buoyancy channel 10.

[0050] See Figure 2 In some other embodiments of this application, a flowable medium 13 for ensuring airtightness may also be provided in the buoyancy channel 10, which is used to transmit the pressure difference between indoor and outdoor environments while ensuring that indoor airflow and outdoor airflow do not flow. For example, the flowable medium 13 can be a liquid or a vacuum. It is understood that in order to store the flowable medium, the buoyancy channel 10 can be configured as a U-shape, or a second buoyancy member 12 can be provided to space the first buoyancy member. The first buoyancy member and the second buoyancy member 12 form a cavity for accommodating the flowable medium 13. It is understood that the cavity moves as the first buoyancy member and the second buoyancy member 12 move within the buoyancy channel 10.

[0051] Furthermore, the first buoyancy component has an exhaust channel 110. When the first buoyancy component is in the first position, one end of the exhaust channel 110 is connected to the outdoor airflow, and the other end of the exhaust channel 110 is connected to the indoor airflow. That is, it can be understood that the position of the first buoyancy component changes with the change of indoor and outdoor air pressure difference. For example, when the indoor pressure is relatively high, the first buoyancy component is closer to the outdoor air vent 100 in the buoyancy channel 10. When the first buoyancy component moves to the first position in the buoyancy channel 10 (i.e., when the indoor ambient air pressure - outdoor ambient air pressure > a certain pressure value), at this time, one end of the exhaust channel 110 in the first buoyancy component is connected to the outdoor airflow, and the other end of the exhaust channel 110 is connected to the indoor airflow.

[0052] It is understood that the specific implementation of the exhaust duct 110, with one end connected to the outdoor airflow and the other end connected to the indoor airflow, is not specifically limited in this application. For example:

[0053] In some embodiments of this application, the exhaust body 1 is provided with an indoor exhaust vent 1100 connecting the interior and an outdoor exhaust vent 1101 connecting the exterior on the side wall corresponding to the buoyancy channel 10. When the first buoyancy member is in the first position, one end of the exhaust channel 110 is connected to the indoor exhaust vent 1100, and the other end of the exhaust channel 110 is connected to the outdoor exhaust vent 1101. That is, the exhaust channel 110 and the indoor exhaust vent 1100 and the outdoor exhaust vent 1101 are connected by airflow. It can be understood that the indoor exhaust vent 1100 can be connected to an indoor air duct to achieve communication with indoor air, and the outdoor exhaust vent 1101 can be connected to an outdoor air duct to achieve communication with outdoor air.

[0054] In some other embodiments of this application, the exhaust body 1 is provided with an indoor exhaust vent 1100 connecting to the room on the side wall corresponding to the buoyancy channel 10, and the first buoyancy member is provided with an outdoor exhaust vent 1101 connecting the exhaust channel 110 and the outdoor air vent 100. That is, one end of the exhaust channel 110 is connected to the outdoor air vent 100, and the other end of the exhaust channel 110 is connected to the indoor exhaust vent 1100 provided on the exhaust body 1. The indoor exhaust vent 1100 can be connected to the indoor air through an indoor air duct, or connected to the indoor air vent 101 on the exhaust body 1 through an indoor air duct. It can be understood that the indoor air duct can be provided inside the exhaust body 1, or it can be provided independently of the exhaust body 1.

[0055] The above implementation provides an exhaust device in which indoor air enters the buoyancy channel 10 through the indoor air inlet 101 and outdoor air enters the buoyancy channel 10 through the outdoor air inlet 100. When the indoor pressure is greater than the outdoor pressure, the first buoyancy component slides within the buoyancy channel 10 based on the indoor-outdoor pressure difference. When the first air pressure buoyancy component 11 is in the first position, one end of the exhaust channel 110 is connected to the outdoor airflow, and the other end of the exhaust channel 110 is connected to the indoor airflow, thereby achieving indoor exhaust to reduce indoor pressure and improve user comfort.

[0056] Furthermore, based on the above implementation scheme, this application also provides an implementation scheme for an exhaust device, wherein the buoyancy channel 10 is a U-shaped channel, the buoyancy channel 10 includes a first straight channel segment 102, a second straight channel segment 103, and a channel bend segment 104 disposed between the first straight channel segment 102 and the second straight channel segment 103, thereby forming a U-shaped channel. The two ends of the buoyancy channel 10 are respectively an indoor air inlet 101 and an outdoor air inlet 100, used to connect the indoor and outdoor environments. The outdoor air inlet 100 is located at one end of the first straight channel segment 102, and the indoor... An indoor air vent 101 is located at one end of a straight section 103 of the second channel; that is, the first buoyancy member is located in the straight section 102 of the first channel corresponding to the outdoor air vent 100 of the buoyancy channel 10, and the second buoyancy member 12 is located in the straight section 103 of the second channel corresponding to the indoor air vent 101; when the first air pressure buoyancy member 11 is in the first position, the distance between the second buoyancy member 12 and the channel bend 104 of the buoyancy channel 10 is less than the distance between the first buoyancy member and the channel bend 104 of the buoyancy channel 10, that is, the indoor air pressure is greater than the outdoor air pressure.

[0057] Specifically, in the embodiments of this application, the exhaust body 1 is also U-shaped corresponding to the buoyancy channel 10, which reduces the weight of the exhaust body 1 and lowers the cost.

[0058] Specifically, the space between the first buoyancy member and the second buoyancy member 12 is filled with a flowable medium 13. In this embodiment, the flowable medium 13 is a liquid, such as water. The flowable medium 13 is disposed in the curved section 104 of the channel between the first buoyancy member and the second buoyancy member 12. By setting the flowable medium 13 to be a liquid, the indoor and outdoor airflow is prevented from flowing in the buoyancy channel 10, thereby enhancing the airtightness of the first buoyancy member and ensuring the exhaust performance of the exhaust device.

[0059] Furthermore, by setting a second buoyancy component 12 to separate the flowable medium 13 and prevent liquid evaporation, it can be understood that the second buoyancy component 12 and the first buoyancy component have the same material and structure. When the pressure difference in the room is the same, the first buoyancy component and the second buoyancy component 12 shown can be located on the same horizontal plane, that is, they are aligned in the buoyancy channel 10. At this time, the exhaust channel 110 is not connected to the indoor exhaust vent 1100 and the outdoor exhaust vent 1101.

[0060] Specifically, in the embodiments of this application, when the exhaust device is installed, the first straight section 102 and the second straight section 103 of the channel are both vertically arranged relative to the ground, and the indoor air inlet 101 and the outdoor air inlet 100 of the buoyancy channel 10 are located at one end of the exhaust body 1 that is perpendicular to the ground.

[0061] Furthermore, based on the above implementation scheme, this application also provides another implementation scheme for the exhaust device, wherein the buoyancy channel 10 is further provided with a position detection device for detecting the position information of the first air pressure buoyancy component 11 and sending the position information to the fresh air conditioner that communicates with the exhaust device.

[0062] The position detection device is used to detect the position information of the first buoyancy component. For example, in some embodiments of this application, the position detection device can be a detection circuit device located within the buoyancy channel 10 corresponding to the exhaust body 1. By detecting the pressure signal of the first buoyancy component, the detection circuit is triggered to connect, thereby detecting the position information of the first buoyancy component. In other embodiments of this application, the position detection device can also be an infrared distance detection device, which detects the position information of the first buoyancy component within the buoyancy channel 10 through the principle of infrared reflection.

[0063] Specifically, the position detection device is communicatively connected to the fresh air conditioner and is used to feed back the position information of the first buoyancy component to the fresh air conditioner so that the fresh air conditioner can detect the exhaust status of the exhaust device and adjust the fresh air supply accordingly to avoid wasting the work done by the air conditioner.

[0064] The exhaust device provided in the above implementation scheme includes at least: an exhaust body 1, wherein a buoyancy channel 10 is provided inside the exhaust body 1; one end of the buoyancy channel 10 is provided with an outdoor air outlet 100 for communicating with the outdoor airflow, and the other end of the buoyancy channel 10 is provided with an indoor air outlet 101 for communicating with the indoor airflow; a first air pressure buoyancy component 11 is provided inside the buoyancy channel 10, the first air pressure buoyancy component 11 slides within the buoyancy channel 10, and an exhaust channel 110 is provided inside the first air pressure buoyancy component 11; when the first air pressure buoyancy component 11 is in a first position, one end of the exhaust channel 110 is connected to the outdoor airflow, and the other end of the exhaust channel 110 is connected to the indoor airflow; the exhaust device is communicatively connected to a fresh air conditioning unit, and the fresh air conditioning unit obtains... The position information of the first air pressure buoyancy component 11 in the exhaust device is obtained. In actual use, indoor air enters the buoyancy channel 10 through the indoor air inlet 101, and outdoor air enters the buoyancy channel 10 through the outdoor air inlet 100. When the indoor pressure is greater than the outdoor pressure, the first buoyancy component slides in the buoyancy channel 10 based on the indoor and outdoor pressure difference. When the first air pressure buoyancy component 11 is in the first position, one end of the exhaust channel 110 is connected to the outdoor airflow, and the other end of the exhaust channel 110 is connected to the indoor airflow, so as to realize indoor exhaust to reduce the indoor pressure. Furthermore, when the fresh air air conditioner detects that the exhaust device is exhausting indoor air, it adjusts the fresh air fan in conjunction with the indoor air quality control to avoid increasing the work of the air conditioner, ensure the balance of the indoor and outdoor pressure difference, and increase user comfort.

[0065] Furthermore, based on any of the above embodiments, this application also provides an air conditioning fresh air control method, which is applied to an air conditioner, the air conditioner including a fresh air conditioner and an exhaust device as described in any of the above embodiments, see [link to relevant documentation]. Figure 3 , Figure 3 A flowchart illustrating one embodiment of the air conditioning fresh air control method provided in this application includes steps S301-S303:

[0066] S301. When the fresh air conditioner is detected to be turned on, indoor air quality parameters are obtained.

[0067] The fresh air conditioner, i.e., the air conditioner with fresh air intake function, can be understood to control the fresh air to start when the fresh air conditioner is turned on in fresh air mode, i.e., to detect the fresh air to start.

[0068] It is understood that when the fresh air system is turned on, the fresh air start-up parameters can be controlled according to the fresh air control logic of the fresh air conditioner. For example, the fresh air system may operate at a preset fan speed, or the fresh air fan may operate according to a preset speed change logic. This application does not make any specific limitations.

[0069] The indoor air quality parameters, i.e., the parameters used to determine indoor air quality, can be, for example, indoor carbon dioxide concentration, inhalable particulate matter data, formaldehyde concentration, etc., or air quality parameters obtained based on parameters corresponding to factors affecting indoor air quality, such as indoor carbon dioxide concentration, inhalable particulate matter data, formaldehyde concentration, etc. For example, obtaining indoor carbon dioxide concentration, inhalable particulate matter data, and formaldehyde concentration, and calculating the corresponding indoor air quality parameters based on indoor carbon dioxide concentration, inhalable particulate matter data, and formaldehyde concentration.

[0070] It is understood that the indoor air quality parameters can be collected and obtained by detection devices, such as carbon dioxide concentration detection devices and formaldehyde concentration detection devices, or can be calculated based on the data detected by the detection devices. This application does not make specific limitations.

[0071] S302. If the indoor air quality parameters meet the preset high-quality parameter conditions, then obtain the position information of the first buoyancy component in the exhaust device.

[0072] The preset high-quality parameter conditions correspond to preset indoor air quality parameters, and this application does not impose specific limitations, such as:

[0073] In one embodiment of this application, the indoor quality parameter is the indoor carbon dioxide concentration, and the quality parameter condition is that the indoor carbon dioxide concentration is greater than a preset carbon dioxide concentration threshold.

[0074] In another embodiment of this application, the indoor quality parameter is an indoor air quality parameter calculated based on indoor carbon dioxide concentration and inhalable particulate matter data. If the indoor air quality parameter is a score or data, the condition is that the indoor air quality parameter is greater than a preset air quality parameter threshold. If the indoor air quality parameter is a level, such as excellent, good, medium, and poor, the indoor air quality parameter meets the preset excellent parameter condition, which can be that the quality parameter is excellent or good. This application does not make specific limitations on the specific condition.

[0075] The location information, namely the ventilation information of the first buoyancy component in any of the above-mentioned ventilation devices within the buoyancy channel, can be understood to be detected by installing a position detection device within the buoyancy channel, such as a position sensor or an infrared rangefinder. After detecting the location information of the first buoyancy component, the location information is sent to the fresh air conditioner that communicates with the ventilation device, that is, the fresh air conditioner obtains the location information of the first buoyancy component in the ventilation device.

[0076] It is understood that the position information of the first buoyancy component can be detected by the position detection device after receiving the position detection command of the fresh air conditioner, and the detected position information can be sent to the fresh air conditioner; or the position detection device can detect the position information at regular intervals and send the position information carrying the detection time to the fresh air conditioner, which can directly obtain it when needed. This application does not make any specific limitations.

[0077] S303. Control the fresh air conditioner to adjust the fresh air intake according to the location information.

[0078] Specifically, after obtaining the position information of the first buoyancy component in the exhaust device, the fresh air conditioner judges the position information of the first buoyancy component. If the position information of the first buoyancy component is the first position, it means that the indoor pressure is relatively high, so the fresh air intake of the air conditioner is reduced. Otherwise, the fresh air intake of the room is adjusted and controlled according to the original fresh air intake control logic.

[0079] Wherein, the first position, that is, the first position described in any of the above-mentioned exhaust fan implementation schemes, when the first buoyancy device is in the first position, the two ends of the exhaust channel provided in the first buoyancy component are respectively connected to the indoor airflow and the outdoor airflow.

[0080] Specifically, this application does not specify the exact method by which the fresh air conditioning system adjusts the fresh air intake based on the location information, for example...

[0081] In some embodiments of this application, controlling the fresh air conditioner to adjust the fresh air intake according to the location information includes: if the location information is a preset first position, then controlling the speed of the fresh air fan of the fresh air conditioner to decrease.

[0082] In some embodiments of this application, controlling the fresh air conditioner to adjust the fresh air intake according to the location information includes: if the location information is a preset first position, then controlling the opening of the fresh air intake damper of the fresh air conditioner to reduce the fresh air intake volume.

[0083] Specifically, in some embodiments of this application, the first position includes multiple sub-positions. Different sub-positions correspond to different exhaust volumes of the exhaust device. That is, when the first buoyancy member is in different sub-positions, the exhaust channel within the first buoyancy member is connected to both the indoor airflow and the outdoor airflow to achieve indoor exhaust, but the corresponding indoor exhaust volumes are different. It can be understood that the first buoyancy member slides within the buoyancy channel, and at least the indoor exhaust port is located on the side wall of the exhaust body corresponding to the buoyancy channel, connecting the buoyancy channel and the indoor airflow. When the indoor air pressure is high, the first buoyancy member will slide to the first sub-position of the first position. At this time, one end of the exhaust channel is not completely aligned with the indoor exhaust port, but the airflow is connected. As the indoor air pressure increases, the first buoyancy member will continue to slide to different sub-positions. As a result, the cross-section of the exhaust channel that is not connected to the indoor exhaust port becomes larger, and the exhaust volume becomes larger. Therefore, different sub-positions correspond to different exhaust volumes of the exhaust device.

[0084] It is understandable that the number of sub-positions can be designed according to the actual fresh air volume control accuracy. If the accuracy requirement is high, the number of sub-positions can be designed to be more, and vice versa. For example, the number of sub-positions can be set to three: the sub-position when the exhaust duct is just connected to the indoor exhaust vent, the sub-position when the exhaust duct is half connected to the indoor exhaust vent, and the sub-position when the exhaust duct is fully connected to the indoor exhaust vent.

[0085] Based on this, see Figure 4 , Figure 4 In some other embodiments of the air conditioning fresh air control method provided in this application, a flowchart of one embodiment of the fresh air intake adjustment includes steps S401-S402:

[0086] S401. If the location information is any one of the multiple sub-locations, then look up the preset mapping table corresponding to the sub-location and the wind turbine parameters to obtain the target wind turbine parameters corresponding to the target sub-location.

[0087] The target sub-position, that is, any one of the multiple sub-positions included in the first position, is the current position of the first buoyancy component detected by the position detection device.

[0088] The preset mapping table corresponding to the sub-location and the fan parameter includes multiple sets of mapping relationships between sub-location and fan parameter. Each set of mapping relationships between location and fan parameter includes one sub-location and one fan parameter.

[0089] Specifically, after the fresh air fan obtains the position information of the first buoyancy component, if the position information is any one of the multiple sub-positions, the target sub-position is input into a preset mapping table to obtain the target fan parameters corresponding to the target sub-position.

[0090] S402. Control the operation of the fresh air fan of the fresh air conditioner according to the target fan parameters to reduce the speed of the fresh air fan of the air conditioner.

[0091] The fresh air fan, which controls the intake of fresh air, specifically refers to the fan that controls the intake of fresh air.

Furthermore, when the fresh air conditioner detects that the exhaust device is exhausting indoor air, it adjusts the fresh air fan in conjunction with the indoor air quality control to avoid increasing the work of the air conditioner, ensure the balance of the indoor and outdoor pressure difference, and increase user comfort.
