Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of indoor fresh air replacement, for example to a method and device for controlling a fresh air module, a fresh air module and an air conditioning device. BACKGROUND

[0002] With the increasing attention to air quality, users have higher and higher requirements for air quality in living rooms, bedrooms and other daily indoor environments. There are many factors that can cause the decline of indoor air quality, for example, formaldehyde, benzene and ammonia air pollutants volatilized from indoor decoration materials, or a large amount of harmful gases such as carbon dioxide and formaldehyde accumulated in the indoor environment due to closed doors and windows at night. Such air quality problems will more or less affect the health of users in the indoor environment, such as inducing users to have symptoms such as chest tightness, shortness of breath, dry mouth and throat, and difficulty breathing.

[0003] One of the effective methods to solve the above air quality problems is to maintain the ventilation between indoor and outdoor environments, and to introduce fresh outdoor air into the indoor environment to increase the oxygen content and reduce the concentration of air pollutants. In this case, the "fresh air conditioner" product emerges as the times require. The fresh air conditioner is a product that adds a fresh air module and a fresh air pipe to the traditional air conditioner, and uses a fan to suck fresh outdoor air into the indoor environment to improve the indoor air quality.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

[0005] In the related product design, there is also a fresh air module scheme with outdoor fresh air and indoor exhaust air dual functions. The internal air cavity of the fresh air module is provided with an intermediate partition plate. The intermediate partition plate can separate the air cavity into an outdoor fresh air cavity and an indoor dirty air cavity, and enable the outdoor fresh air to be introduced into the indoor environment through the outdoor fresh air cavity, and the indoor dirty air to be discharged to the outdoor environment through the indoor dirty air cavity. However, the intermediate partition plate is in the form of a fixed partition plate, and the outdoor fresh air cavity and the indoor dirty air cavity are also fixed cavity volumes. Therefore, the outdoor fresh air volume and the indoor dirty air volume of the fresh air module cannot be adjusted.

[0006] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present application, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art.

[0058] The term "corresponding" can refer to an association relationship or a binding relationship. A and B correspond to each other means that there is an association relationship or a binding relationship between A and B.

[0059] The present application provides a fresh air module 1, which can be applied to air conditioning equipment such as wall-mounted air conditioners, fresh air machines, and humidification machines, to controllably achieve the functions of separately introducing outdoor fresh air, separately discharging indoor dirty air, and / or simultaneously introducing outdoor fresh air and discharging indoor dirty air, thereby improving indoor air quality and enhancing environmental comfort.

[0060] As Figure 1 , 1aAs shown, the fresh air module 1 mainly comprises a module housing 10, a fresh air duct 20, an air outlet switching part 30 and the like. The module housing 10 is internally structured with an air cavity defining an air flow path, and can serve as a space for accommodating components such as an air filter 14, an impeller 122 and the like. Here, the module housing 10 is provided with an indoor air opening for communicating with the indoor side, and an outdoor air opening 114 for communicating with the outdoor side. The indoor air opening comprises an indoor air outlet and / or an indoor return air opening 113, the indoor air outlet being an air opening through which the fresh air module 1 sends air to the indoor side, and the indoor return air opening 113 being an air opening through which air flows from the indoor side to the fresh air module 1; the outdoor air opening 114 being an air opening through which the fresh air module 1 discharges air to the outdoor side or the outdoor side delivers fresh air to the fresh air module 1. The fresh air duct 20 extends from the indoor side to the outdoor side, and serves as a through-wall passage for introducing outdoor fresh air and / or discharging indoor dirty air, the fresh air duct 20 being in communication with the air cavity of the module housing 10, thereby jointly defining an outdoor fresh air introduction path and / or an indoor dirty air discharge path. The air outlet switching part 30 is arranged at the air outlet side of the module housing 10, and is used to define the air outlet flow direction of at least part of the air flow flowing through the module housing 10, the at least part of the air flow comprising outdoor fresh air or indoor dirty air, and the air outlet flow direction comprising a flow direction to the indoor side or the outdoor side, thereby achieving the functions of introducing outdoor fresh air and / or discharging outdoor dirty air and the like.

[0061] In some optional embodiments, in combination with Figure 2 As shown, the air cavity of the module housing 10 comprises an air inlet cavity 11 and a fan cavity 12, and the air inlet cavity 11 is in communication with the fan cavity 12, and air can flow between the air inlet cavity 11 and the fan cavity 12. The air inlet cavity 11 can be used to accommodate components such as a partition component, an air filter 14 and the like, and the air inlet cavity 11 is in communication with one or more of the indoor air opening, the outdoor air opening 114. The fan cavity 12 can be used to accommodate components such as an impeller 122 and the like, and the fan cavity 12 is in communication with one or more of the indoor air opening, the outdoor air opening 114.

[0062] Optionally, the air inlet cavity 11 is upstream of the fan cavity 12 in the air flow path, that is, the fan cavity 12 is located at the air outlet side of the air inlet cavity 11, thereby defining an air flow direction in the module housing 10 from the air inlet cavity 11 to the fan cavity 12. Alternatively, the air inlet cavity 11 is downstream of the fan cavity 12 in the air flow path, that is, the air inlet cavity 11 is located at the air outlet side of the fan cavity 12, thereby defining an air flow direction in the module housing 10 from the fan cavity 12 to the air inlet cavity 11. Hereinafter, the former structure in which the air inlet cavity 11 is upstream of the fan cavity 12 in the air flow path will be mainly taken as an example for description.

[0063] In some alternative embodiments, the module housing 10 further comprises a first air outlet duct 13 connected to the module housing 10 and located at the air outlet side of the air inlet cavity 11 (the fan cavity 12) for configuring a first indoor air outlet 51 as an air outlet path through which the air flow of the air inlet cavity 11 (the fan cavity 12) can be delivered to the external environment. Similarly, the module housing 10 further comprises a second air outlet duct connected to the module housing 10 and located at the air outlet side of the air inlet cavity 11 (the fan cavity 12) for configuring a second indoor air outlet 52 as an air outlet path through which the air flow of the air inlet cavity 11 (the fan cavity 12) can be delivered to the external environment.

[0064] In the above embodiments, the adjustment of the actual air delivery direction can be achieved by changing the extension direction of the first air outlet duct 13 (and the second air outlet duct), or the orientation of the duct air outlet end. For example, in the above embodiment where the first indoor air outlet 51 is configured to deliver air to the front-upward direction, the first air outlet duct 13 can be formed to extend in the front-upward direction, and the duct air outlet end of the first air outlet duct 13 can be oriented in the front-upward direction.

[0065] Here, the fan cavity 12 is provided at the air outlet side of the air inlet cavity 11, and the first indoor air outlet 51 and the second indoor air outlet 52 are respectively connected to the fan cavity 12 through the fan cavity 12. In embodiments, the first indoor air outlet 51 and the second indoor air outlet 52 are respectively connected to the outer peripheral shell wall of the fan volute, wherein the first indoor air outlet 51 is connected to the top position of the outer peripheral shell wall, and the second indoor air outlet 52 is connected to the bottom position of the outer peripheral shell wall. In the fan cavity 12, the impeller 122 rotates in a downward direction, and the air located upstream of the first indoor air outlet 51 in the rotation direction is preferentially concentrated to flow to the first indoor air outlet 51, as shown by the solid arrow air flow in Figure 4b , and the air located upstream of the second indoor air outlet 52 in the rotation direction is preferentially concentrated to flow to the second indoor air outlet 52, as shown by the dashed arrow air flow in Figure 4b .

[0066] In some embodiments, as shown in Figure 4b , the fan volute is provided with a first volute air outlet and a second volute air outlet. The first volute air outlet is provided at the top position of the outer peripheral shell wall of the fan volute, and is used to connect the fan volute and the first indoor air outlet 51, so that at least part of the air flow in the fan volute is delivered to the first indoor air outlet 51 through the first volute air outlet. The second volute air outlet is provided at the bottom position of the outer peripheral shell wall of the fan volute, and is used to connect the fan volute and the second indoor air outlet 52, so that at least part of the air flow in the fan volute is delivered to the second indoor air outlet 52 through the second volute air outlet.

[0067] In some embodiments, as shown in Figures 3a to 3hAs shown, the air inlet cavity 11 comprises a first sub-air inlet cavity 115 and a second sub-air inlet cavity 116, and the two are arranged separately, and the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116 respectively form a relatively independent air path. The air flowing into the air inlet cavity 11 is divided into the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116, and continues to be transported along the respective air paths to the fan cavity 12.

[0068] Optionally, the air inlet cavity 11 is provided with a separation component for separating the air inlet cavity 11 into the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116.

[0069] Optionally, the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116 can respectively flow the air from the same air source, for example, the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116 are simultaneously used for transporting outdoor fresh air from the outdoor side, or simultaneously used for transporting indoor dirty air from the indoor side.

[0070] Alternatively, the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116 can respectively flow the air from different air sources, for example, one of the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116 is used for transporting outdoor fresh air from the outdoor side, and the other is used for transporting indoor dirty air from the indoor side. Here, the separation component can at least be used to separate the air paths when the two sub-air inlet cavities 11 transport air from different air sources, and to block or slow down the mixing of air with different cleanliness states.

[0071] In some embodiments, in combination with Figure 3b As shown, the separation component is movably arranged in the air inlet cavity 11 of the module shell 10, and can be controlled to adjust the relative position with the air inlet cavity 11 to change the cavity space of the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116. In the embodiment of the present disclosure, the fresh air module 1 movably arranges the separation component in the air inlet cavity 11, so that during the movement of the separation component, the cavity space of the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116 separated by the separation component can be changed, thereby achieving the effect of adjusting the fresh air inlet amount and the dirty air exhaust amount.

[0072] Optionally, the separation component is in the form of rotation, sliding, etc. relative to the air inlet cavity 11 to realize the adjustment of the relative position of the separation component with the air inlet cavity 11.

[0073] Here, the separation component can separate the air outlet of the air inlet cavity into a first sub-air outlet and a second sub-air outlet, and the first sub-air outlet and the second sub-air outlet correspond to the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116, respectively, as the path for the airflow output from the two sub-air inlet cavities to the fan cavity 12. In this way, during the operation of the separation component relative to the air inlet cavity 11, such as rotation, sliding, etc., the relative position of the separation component and the air outlet 112 of the air inlet cavity 11 can be changed, so that the separation boundary position of the first sub-air outlet and the second sub-air outlet by the separation component is changed, and then the outdoor fresh air volume of the first sub-air inlet cavity 115 and / or the indoor dirty air volume of the second sub-air inlet cavity 116 is changed.

[0074] Specifically, in some optional embodiments, as shown in Figure 3b and 3d , the separation component is pivoted to the air inlet cavity 11, so that the separation component can rotate relative to the air inlet cavity 11, thereby achieving the purpose of adjusting the relative position of the separation component and the air inlet cavity 11.

[0075] In the embodiment, the separation component includes a movable partition plate 181 and a partition plate driver 182, and the partition plate driver 182 can drive the movable partition plate 181 to rotate in the air inlet cavity 11.

[0076] Here, the movable partition plate 181 is pivoted in the air inlet cavity 11, and the rotation plane thereof is parallel to the wall surface of the air outlet cavity wall. Alternatively, the movable partition plate 181 is pivoted to another cavity wall of the air inlet cavity 11 relative to the air outlet cavity wall, i.e., the outer cavity wall 115 in the foregoing embodiment, and a through hole is formed in the outer cavity wall for the motor shaft to pass through. The partition plate driver 182 includes a partition plate driving motor and a motor shaft, as shown in Figure 3d , the partition plate driving motor is fixed to the outer wall surface of the outer cavity wall, the motor shaft thereof extends into the air inlet cavity 11 through the through hole, and is fixedly connected with the movable partition plate 181, so that the partition plate driving motor can drive the movable partition plate 181 to rotate through the motor rotation.

[0077] In the embodiment, the partition plate driving motor is a bidirectional rotation motor type, so as to selectively drive the movable partition plate 181 to rotate in the clockwise direction or the counterclockwise direction.

[0078] In the embodiment, similar to the separation plate shown in the foregoing embodiment, the movable partition plate 181 and at least a part of the cavity wall of the air inlet cavity 11 form the first sub-air inlet cavity 115, and at least another part of the cavity wall of the air inlet cavity 11 form the second sub-air inlet cavity 116. In this way, when the movable partition plate 181 rotates around the shaft in the air inlet cavity 11, the cavity space of the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116 surrounded thereby can be changed.

[0079] Optionally, the air inlet cavity 11 is constructed as a cavity with a circular or nearly circular overall outer contour, and the rotation axis of the movable baffle 181 is located at the center of the air inlet cavity 11. Thus, the longitudinal ends of the movable baffle 181 extend to the inner circumference of the air inlet cavity 11 and can be driven by the baffle driver 182 to rotate along the circumference of the air inlet cavity 11. Alternatively, the movable baffle 181 can be a straight plate or a non-straight plate. Optionally, the non-straight plate includes curved, polygonal, or other shapes, or a plate form composed of one or more straight segments and / or one or more curved segments joined together.

[0080] Optionally, the partition component may further include one or more static partitions that may cooperate with the dynamic partition 181 to jointly define the respective sub-inlet chambers and / or the rotation area where the dynamic partition 181 is located.

[0081] Specifically, combined Figure 3c As shown, the separating components include a first static partition 183 and / or a second static partition 184. Optionally, the first static partition 183 is disposed on the side wall of the air inlet cavity 11 where the outdoor air vent 114 and the indoor return air vent 113 are located, and extends into the cavity of the air inlet cavity 11; the first static partition 183 can separate the outdoor air vent 114 and the indoor return air vent 113, so as to limit the outdoor air vent 114 to the space of the first sub-air inlet cavity 115 and the indoor return air vent 113 to the space of the second sub-air inlet cavity 116. Alternatively, the second static partition 184 is disposed on the side wall opposite to the side wall where the first static partition 183 is located, and also extends into the cavity of the air inlet cavity 11; the second static partition 184 can separate the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116.

[0082] In this embodiment, the first static partition 183 and the second static partition 184 are spaced apart, and the rotation area of ​​the moving partition 181 is located in the space between them.

[0083] Thus, one side of the moving partition 181, one side of the first stationary partition 183, one side of the second stationary partition 184, and at least a portion of the cavity wall of the air inlet cavity 11 together form a first sub-air inlet cavity 115. And, the other side of the moving partition 181, the other side of the first stationary partition 183, the other side of the second stationary partition 184, and at least another portion of the cavity wall of the air inlet cavity 11 together form a second sub-air inlet cavity 116.

[0084] Optionally, combined Figure 3cAs shown, the first static baffle 183 comprises a first straight plate segment 1831 and a first arc segment 1832. The first straight plate segment 1831 is fixedly connected with the second side wall 1112 at one longitudinal end thereof, and the fixed position is located between the outdoor air inlet 114 and the indoor air return inlet 113, and the other end extends towards the inner side of the air inlet cavity 11. One end of the first arc segment 1832 is fixedly connected with the extending end of the first straight plate segment 1831, and the other end is a free end. The first arc segment 1832 is integrally formed along the rotating outer circumferential line of the first outer plate end of the movable baffle 181, and the first outer plate end of the movable baffle 181 is slidably abutted on the inner plate surface of the first arc segment 1832. Alternatively, the end of the first arc segment 1832 connected with the first straight plate segment 1831 can be further extended along the direction of the rotating outer circumferential line to expand the rotating range of the first outer plate end.

[0085] Similarly, in combination with the above description of the first static baffle 183, Figure 3c As shown, the second static baffle 184 comprises a second straight plate segment 1841 and a second arc segment 1842. The first straight plate segment 1831 is fixedly connected with the first side wall 1111 at one longitudinal end thereof, and the other end extends towards the inner side of the air inlet cavity 11. One end of the second arc segment 1842 is fixedly connected with the extending end of the second straight plate segment 1841, and the other end is a free end. The second arc segment 1842 is integrally formed along the rotating outer circumferential line of the second outer plate end of the movable baffle 181, and the second outer plate end of the movable baffle 181 is slidably abutted on the inner plate surface of the second arc segment 1842. Alternatively, the end of the second arc segment 1842 connected with the second straight plate segment 1841 can be further extended along the direction of the rotating outer circumferential line to expand the rotating range of the second outer plate end.

[0086] Alternatively, the arc lengths of the first arc segment 1832 and the second arc segment 1842 are substantially equal.

[0087] In the present embodiment, the rotating range of the movable baffle 181 is limited to the angle range corresponding to the circular segment with the shortest arc length among the first arc segment 1832 and the second arc segment 1842. In this way, it can be ensured that the first outer plate end of the movable baffle 181 can always abut on the first arc segment 1832, and the second outer plate end of the movable baffle 181 can always abut on the second arc segment 1842 during the rotation of the movable baffle 181.

[0088] In some embodiments, the fresh air module further comprises an inlet port set, which comprises a first inlet port and a second inlet port. The first inlet port is arranged on the wall of the first sub-inlet cavity 115, and is used to introduce outdoor fresh air into the first sub-inlet cavity 115. Optionally, the first inlet port is the outdoor air inlet port 114 in the previous embodiments, which is arranged on the second side wall 1112 of the inlet cavity 11. The second inlet port is arranged on the wall of the second sub-inlet cavity 116, and is used to introduce indoor contaminated air into the second sub-inlet cavity 116. Optionally, the second inlet port is the indoor return air inlet port 113 in the previous embodiments, which is arranged on the second side wall 1112 of the inlet cavity 11.

[0089] In yet some embodiments, the fresh air module further comprises an outlet port set, which comprises a first outlet port and a second outlet port. Optionally, the outlet port set is arranged in the fan cavity 12 of the fresh air module, and the first outlet port corresponds to the first sub-inlet cavity 115, and the second outlet port corresponds to the second sub-inlet cavity 116. When the fan cavity is rotated downward, at least part of the airflow of the first sub-inlet cavity 115 is diverted to flow toward the first outlet port, and at least part of the airflow of the second sub-inlet cavity 116 is diverted to flow toward the second outlet port. In embodiments, the first outlet port is used to output outdoor fresh air from the first sub-inlet cavity 115 to the indoor side, and the second outlet port is used to output indoor contaminated air from the second sub-inlet cavity 116 to the outdoor side, or to output indoor contaminated air filtered from the second sub-inlet cavity 116 to the indoor side.

[0090] Optionally, the first outlet port is a first volute outlet port, and the second outlet port is a second volute outlet port.

[0091] Further optionally, the extension coverage of the first arc segment 1832 and the second arc segment 1842 is limited to: when the movable partition 181 is rotated to a first position, the first position is that the first outer plate end of the movable partition 181 is located at the distal end of the first arc segment 1832, or the second outer plate end of the movable partition 181 is located at the distal end of the second arc segment 1842, as shown in FIG. 18B, at least part of the cavity space of the second sub-inlet cavity 116 corresponds to the upstream of the air path of the first volute outlet port, and at least part of the cavity space of the first sub-inlet cavity 115 corresponds to the upstream of the air path of the second volute outlet port, so that part of the fresh air flow of the first sub-inlet cavity 115 is diverted to the second volute outlet port, and then discharged to the outdoor side through the second volute outlet port, as shown in FIG. 18C, the fresh air flow corresponding to the C1 region; and part of the contaminated air flow of the second sub-inlet cavity 116 is diverted to the first volute outlet port, as shown in FIG. 18D, the contaminated air flow corresponding to the C2 region. Figure 3e Figure 3e Figure 3e

[0092] ​​​Therefore, compared with the fixed partition plate form in the foregoing embodiments, part of the indoor dirty air is replaced by part of the outdoor fresh air to be output to the indoor side, the part of the outdoor fresh air replaced is discharged to the outdoor side again, and thus the amount of the outdoor fresh air output to the indoor side by the movable partition plate 181 in the first position is reduced.

[0093] Further optionally, the extension coverage of the first circular arc segment 1832 and the second circular arc segment 1842 is limited as follows: when the movable partition plate 181 is rotated to the second position, the first position is that the first outer plate end of the movable partition plate 181 is located at the proximal end of the first circular arc segment 1832 or the second outer plate end of the movable partition plate 181 is located at the proximal end of the second circular arc segment 1842, as shown in FIG. 18B. Figure 3f As shown in FIG. 18B, all or most of the cavity space of the first sub-air inlet cavity 115 corresponds to the upstream of the air path of the first volute air outlet, and all or most of the cavity space of the second sub-air inlet cavity 116 corresponds to the upstream of the air path of the second volute air outlet, so that all or most of the fresh air flow of the first sub-air inlet cavity 115 is diverted to the first volute air outlet, and all or most of the dirty air flow of the second sub-air inlet cavity 116 is diverted to the second volute air outlet.

[0094] Optionally, the proximal end of the first circular arc segment 1832 corresponds to the first volute tongue segment, and / or the proximal end of the second circular arc segment 1842 corresponds to the second volute tongue segment. Therefore, compared with the use state of the movable partition plate 181 in the first position, the amount of the outdoor fresh air output to the indoor side by the movable partition plate 181 in the second position is significantly increased, and the diversion air supply effect is close to the fixed partition plate form in the foregoing embodiments.

[0095] In this way, the person skilled in the art can move the movable partition plate 181 between the first position and the second position and select the actual partition air supply position according to actual needs, to dynamically adjust the air volume output ratio of the outdoor fresh air and the indoor dirty air. When the movable partition plate 181 moves from the first position to the second position, the proportion of the fresh air output through the first volute air outlet gradually increases, and the proportion of the dirty air output through the second volute air outlet gradually increases. When the movable partition plate 181 moves from the second position to the first position, the proportion of the fresh air output through the first volute air outlet gradually decreases, and the proportion of the dirty air output through the second volute air outlet gradually decreases.

[0096] In still some optional embodiments not shown in the drawings, the partition component includes a movable partition plate and a partition plate driver, and the partition plate driver can drive the movable partition plate to move laterally in the air inlet cavity. Here, the movable partition plate is arranged to slide laterally in the air inlet cavity, and the lateral movement plane of the movable partition plate is parallel to the wall surface of the air outlet cavity wall.

[0097] In an embodiment, the partition driving motor is a bidirectional rotating motor type, so as to selectively drive the movable partition to move along a first direction or a second direction in the transverse direction. The first direction and the second direction are two opposite directions. Alternatively, the first direction is moving towards the side where the third side wall is located, and the second direction is moving towards the side where the fourth side wall is located.

[0098] In the present embodiment, similar to the partition shown in the foregoing embodiments, the movable partition and at least one part of the cavity wall of the air inlet cavity form a first sub-air inlet cavity, and at least another part of the cavity wall of the air inlet cavity forms a second sub-air inlet cavity.

[0099] Alternatively, in order to ensure the air tightness between the two sub-air inlet cavities during the transverse movement of the movable partition, the air inlet cavity can be configured in the form of a square cavity, or in other words, the inside of the air inlet cavity is in the form of a square cavity, and the vertical length of the movable partition is consistent with the vertical length of the air inlet cavity. Therefore, during the transverse sliding movement of the movable partition, the longitudinal two ends of the movable partition can always abut against the opposite two side walls of the air inlet cavity, thereby reducing the air leakage gap that may be caused during the movement.

[0100] In this way, when the movable partition moves in the transverse direction in the air inlet cavity, the cavity space of the first sub-air inlet cavity and the second sub-air inlet cavity surrounded by the movable partition can be changed. For example, when the movable partition moves towards the third side wall, the cavity space of the first sub-air inlet cavity and the caliber of the corresponding first sub-air outlet increase, and the cavity space of the second sub-air inlet cavity and the caliber of the corresponding second sub-air outlet decrease. Alternatively, when the movable partition moves towards the fourth side wall, the cavity space of the first sub-air inlet cavity and the caliber of the corresponding first sub-air outlet decrease, and the cavity space of the second sub-air inlet cavity and the caliber of the corresponding second sub-air outlet increase.

[0101] In combination with the foregoing embodiments, the outdoor air outlet and the indoor return air outlet are spaced apart on the second side wall. The outdoor air outlet is used to deliver outdoor fresh air to the first sub-air inlet cavity, and the indoor return air outlet is used to deliver indoor dirty air to the second sub-air inlet cavity. Alternatively, the transverse movement range of the movable partition is limited to the longitudinal one end of the movable partition corresponding to the second side wall, so that the outdoor air outlet always corresponds to the first sub-air inlet cavity, and the indoor return air outlet always corresponds to the second sub-air inlet cavity.

[0102] In the above-mentioned embodiments, the fresh air pipe 20 is connected to the first air inlet, so as to introduce outdoor fresh air into the first air inlet cavity 11; and the second air pipe channel is connected to the second air outlet, so as to discharge indoor dirty air to the outdoor side.

[0103] Optionally, the baffle plate form shown in the previous embodiment for separating the air inlet channel 1223 of the impeller 122 can also be applied to the separation component in this embodiment, so that the separation component can not only dynamically adjust the space of the sub-air inlet cavity in the air inlet cavity 11 during the operation, but also dynamically adjust the channel space change of the air inlet channel 1223 in the fan cavity 12 accordingly, so as to enhance the diversion and air delivery effect of airflow from different sources.

[0104] In conjunction with the preceding embodiments, the first partition plate 191 of the separating component is disposed in the air inlet channel 1223 of the impeller 122, and the second partition plate 192 of the separating component is the movable partition plate 181 in this embodiment. The first partition plate 191 is fixed to the movable partition plate 181 and can move together with the movable partition plate 181, such as... Figure 3g As shown. Here, the first partition plate 191 is a design for a movable partition plate 181 that moves relative to the air inlet cavity 11 in a rotatable manner.

[0105] Optionally, the partition driver 182 can be driven to connect with the first partition 191 or the second partition 192 to drive the first partition 191 to rotate relative to the fan cavity and the second partition 192 to rotate relative to the air inlet cavity 11, so as to change the partition position of the first partition 191 relative to the air inlet channel 1223 and the partition position of the second partition 192 (moving partition 181) relative to the air inlet cavity 11.

[0106] In some alternative embodiments, at least a portion of the impeller driver 126 is located within the air inlet channel 1223 of the impeller 122. Correspondingly, the first partition plate 191 is formed with a clearance groove 1911 to avoid the impeller driver 126, thereby preventing positional interference between the first partition plate 191 and the impeller driver 126 during rotation. Figure 3h As shown.

[0107] Here, the clearance groove 1911 is spaced apart from the impeller driver 126, and the gap between the edge of the groove and the impeller driver 126 is minimized as much as possible while avoiding contact, so as to improve the airtightness and reduce the mixing of airflow between the two air intake areas in the air intake channel 1223 through the gap.

[0108] The following description, in conjunction with the various embodiments of the fresh air module 1 shown above, will explain several air exchange modes of the fresh air module 1 of this application. (Wherein, outdoor fresh air is indicated by solid arrows, and indoor stale air is indicated by dashed arrows.)

[0109] Combination Figures 4a to 4cOptionally, the working modes of the fresh air module 1 include a full fresh air mode. In the full fresh air mode, the fresh air module 1 is used to deliver outdoor fresh air from the outdoor side to the indoor side. In this mode, the fresh air module 1 does not deliver indoor polluted air to the outdoor side. The full fresh air mode can supplement the indoor side with outdoor fresh air of better air quality, thereby improving the air quality of the indoor side.

[0110] In some embodiments, in the full fresh air mode, the outdoor fresh air is delivered to the indoor side via the fresh air duct 20, the air inlet cavity 11, the first indoor air outlet 51 and / or the second indoor air outlet 52. Specifically, in the full fresh air mode, the impeller 122 is kept rotating in a set rotational direction (e.g., the first rotational direction); the baffle of the integrated switch control is moved to the first sliding position, so that the indoor return air outlet 113 is blocked, and the first air duct passage 231 and the second air duct passage 232 of the fresh air duct 20 are both in communication with the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116 of the air inlet cavity 11; the air block of the air outlet switching mechanism is located at the first rotating position, so that the second air duct passage 232 is blocked from the switching air cavity, and the fan cavity 12 is in communication with the first indoor air outlet 51 and the second indoor air outlet 52.

[0111] In this way, when the impeller 122 rotates, a negative pressure suction force is generated on the air inlet cavity 11 side, attracting outdoor fresh air from the outdoor side to flow to the indoor side through the first air duct passage 231 and the second air duct passage 232, and entering the air inlet cavity 11 through the outdoor air outlet 114 of the module housing 10, as shown by the arrow in Figure 4a and 4c , and then the outdoor fresh air flows from the air inlet cavity 11 into the fan cavity 12, and then from the first indoor air outlet 51 and the second indoor air outlet 52, as shown by the arrow in Figure 4b .

[0112] In combination with Figures 5a to 5c , yet another working mode of the fresh air module 1 is a bidirectional air exchange mode. In the bidirectional air exchange mode, the fresh air module 1 is used to simultaneously deliver outdoor fresh air from the outdoor side to the indoor side, and deliver indoor polluted air from the indoor side to the outdoor side. The bidirectional air exchange mode can simultaneously supplement the indoor side with outdoor fresh air and exhaust indoor polluted air from the indoor side, thereby achieving simultaneous replacement of fresh air and polluted air, and improving the indoor air quality more quickly.

[0113] In some embodiments, in the bidirectional air exchange mode, it is divided into two flow paths, an outdoor fresh air flow path and an indoor exhaust air flow path. Specifically, in the bidirectional air exchange mode, the impeller 122 rotates in a set direction (such as the first direction); the baffle of the integrated switch part is moved to the second sliding position to open the indoor return air outlet 113, and the second fresh air outlet 2321 of the second air duct passage 232 is blocked; the air block 32 of the air outlet switching mechanism is located in the second rotating position, so that the branch air outlet 2322 of the second air duct passage 232 is in communication with the switching air chamber, and the switching air chamber is blocked from the second indoor air outlet 52, so that the fan chamber 12 is in communication with the first indoor air outlet 51 and the second air duct passage 232. In this way, when the impeller 122 rotates, a negative pressure suction force is generated on the side of the air inlet chamber 11, which simultaneously attracts outdoor fresh air and indoor dirty air on the indoor side to flow into the air inlet chamber 11. Among them, the outdoor fresh air flow path is that the outdoor fresh air is sequentially transported to the first indoor air outlet 51 through the first air duct passage 231, the first sub-air inlet chamber 115, and the fan chamber 12, and the outdoor fresh air is sent into the indoor environment through the first indoor air outlet 51, as shown by the arrow in FIG. 11. Figure 5a and 5c the indoor exhaust air flow path includes that the indoor dirty air is sequentially transported to the second air duct passage 232 through the indoor return air outlet 113, the second sub-air inlet chamber 116, and the fan chamber 12, and the indoor dirty air is finally discharged to the outdoor side through the second air duct passage 232, as shown by the arrow in FIG. 12. Figure 5b and 5c

[0114] In combination with Figures 6a to 6d In another alternative, the working mode of the fresh air module 1 includes a full return air mode. The full return air mode refers to that the fresh air module 1 is used to transport at least part of the outdoor dirty air from the indoor side to the outdoor side, and / or to filter and purify at least part of the indoor dirty air and then send it back to the indoor side. In this mode, the fresh air module 1 does not transport outdoor fresh air to the indoor side. This mode can be applied to the case where the outdoor environment air quality is also poor, such as smog weather.

[0115] In some embodiments, in the full return air mode, the indoor dirty air is transported to the outdoor side through the indoor return air outlet 113, the air inlet chamber 11, the fan chamber 12, and the second air duct passage 232 (exhaust air duct), and / or the indoor dirty air is sent back to the indoor side through the indoor return air outlet 113, the air inlet chamber 11, the fan chamber 12, and the first indoor air outlet 51. Specifically, in the full return air mode, the impeller 122 rotates in a set direction (such as the first direction); the baffle of the integrated switch part is moved to the third sliding position to block the outdoor air outlet 114 and open the indoor return air outlet 113; the air block 32 of the air outlet switching mechanism is located in the first rotating position or the second rotating position.

[0116] ​In this way, when the impeller 122 rotates, a negative pressure suction force is generated on the side of the air inlet cavity 11, which attracts indoor dirty air on the indoor side to enter the air inlet cavity 11 through the indoor return air port 113 of the module shell 10 and is distributed to the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116, as shown in Figure 6a The indoor dirty air in the first sub-air inlet cavity 115 flows into the fan cavity 12 after being filtered and purified by the air filter element 14, and is then sent back to the indoor side environment from the first indoor air outlet 51, as shown in Figure 6b and 6c The indoor dirty air in the second sub-air inlet cavity 116 flows into the fan cavity 12 after being filtered and purified by the air filter element 14, and is then sent to the switching air cavity. Here, in the case where the air block is located at the first rotating position, the part of the indoor dirty air is sent back to the indoor side environment from the second indoor air outlet 52, as shown in Figure 6b In the case where the air block is located at the second rotating position, the part of the indoor dirty air is discharged to the outdoor side environment from the second air pipe passage 232, as shown in Figure 6c and 6d

[0117] Figure 7 A method for controlling a fresh air module is provided, which is applied to the fresh air module described above.

[0118] In combination with Figure 7 The method for controlling the fresh air module includes:

[0119] S701, the processor obtains a target fresh air amount required in the room.

[0120] S702, the processor determines a target rotating angle according to the target fresh air amount.

[0121] S703, the processor controls the separation component according to the target rotating angle to adjust the cavity space of the first sub-air inlet cavity and the second sub-air inlet cavity.

[0122] The method for controlling the fresh air module provided by the embodiments of the present disclosure sets the separation component in the air inlet cavity in a movable manner, determines a target rotating angle according to a target fresh air amount required in the room, and controls the separation component to adjust the cavity space of the first sub-air inlet cavity and the second sub-air inlet cavity. In this way, the first sub-air inlet cavity and the second sub-air inlet cavity can be adjusted according to the current actual demand, so as to adjust the fresh air inlet amount.

[0123] Optionally, the processor determines the target rotating angle according to the target fresh air amount, including: the processor determines the target rotating angle according to a first corresponding relationship between the fresh air amount and the rotating angle and the target fresh air amount.

[0124] ​Specifically, the fresh air module is simulated, and the partition component is simulated in different positions. The corresponding fresh air volume when the partition component is in different positions is recorded, and the corresponding relationship between the fresh air volume and the position of the partition component is established. The rotation angle is determined according to the position of the partition component and the initial position of the partition component, so as to further establish the first corresponding relationship between the fresh air volume and the rotation angle.

[0125] According to the first corresponding relationship, the rotation angle corresponding to the target fresh air volume can be determined. If the partition component is located at the initial position, the rotation angle is the target rotation angle. If the partition component is not located at the initial position, the target rotation angle is determined according to the rotation angle and the angle between the current partition component and the initial position.

[0126] As shown in Figure 3e and Figure 3f , the first position is the initial position. As the partition plate continuously moves from the first position to the second position, the fresh air volume from the outdoor to the indoor continuously increases, which can quickly reduce the carbon dioxide concentration in the indoor. That is, the greater the rotation angle, the greater the fresh air volume.

[0127] Optionally, the processor determines the target rotation angle according to the target fresh air volume, including: the processor calculates the target rotation angle according to the target fresh air volume-rotation angle formula.

[0128] The determination method of the target fresh air volume-rotation angle formula includes:

[0129]

[0130]

[0131] Wherein: q r is the target fresh air volume, unit m 3 / h; c 2m is the absolute speed of the blade outlet airflow in the vertical plane, unit m / s; β 2A is the blade outlet angle, unit °; w 2∞ is the relative speed of the blade outlet airflow, unit m / s;

[0132] As shown in Figure 8-1 , 8-2 D2, b2 and t are described.

[0133] As shown in Figure 8-1As shown, the impeller 122 includes a hub 1221 and a plurality of blades 1222. The hub 1221 is configured as an annular structure, and the inner space thereof is formed as an air inlet channel of the impeller 122, which extends axially along the impeller 122. The number of the hub 1221 is two, and the two hubs 1221 are coaxially and spaced apart, and the space between the two hubs 1221 is used to accommodate the plurality of blades 1222. Here, each blade 1222 is configured as a strip-shaped structure, and a first end thereof is fixed to one of the hubs 1221, and the other end is fixedly connected to the other hub 1221. As viewed from the projection direction of the axis of the hub 1221, each blade 1222 is arranged at equal intervals along the outer circumferential line of the hub 1221, and is arranged obliquely relative to the outer circumferential line of the hub 1221, so that the air entering the air inlet channel from the impeller 122 in the axial direction is driven by the blades 1222 to diffuse outward in the radial direction, and enters the shell space of the fan volute. In the embodiment, the plurality of blades 1222 are uniformly arranged along the outer circumferential line, and collectively surround to form the air inlet channel 1223.

[0134] In combination with Figure 8-1 and Figure 8-2 , D2 is the diameter of the impeller outlet, unit m; b2 is the blade outlet width, unit m;

[0135] The time T for the blade to rotate one blade interval is calculated as:

[0136]

[0137] Wherein, n is the current impeller speed, unit r / min; N is the total number of blades.

[0138] The blade interval that the partition component needs to rotate is calculated as:

[0139]

[0140] In combination with Figure 8-2 As shown, l is the arc length between the blade inlet and the blade outlet on the radial plane of the impeller, unit m; t is the time for the airflow to pass through the arc l, unit s.

[0141] In combination with formulas (1), (2), (3), and (4), the blade interval k that needs to be rotated is determined, unit: number. That is, the rotation angle is determined as rotating k blade intervals. If the current partition component is in the initial position, the target rotation angle is determined as the rotation angle, that is, rotating k blade intervals. If the current partition component is not in the initial position, the target rotation angle is determined according to the included angle between the current position and the initial position and the rotation angle, so that after rotating the target rotation angle, the included angle between the partition component and the initial position is the rotation angle. In this way, the accurate target rotation angle can be calculated according to the target fresh air volume and the actual parameters of the fresh air module.

[0142] Optionally, the processor controls the separation component according to the target rotation angle, including: the processor controls the baffle driver to operate to rotate the movable baffle by the target rotation angle.

[0143] Optionally, after the processor controls the separation component according to the target rotation angle, the method further includes: the processor obtains the indoor carbon dioxide concentration, and controls the impeller to increase the rotating speed in the case that the carbon dioxide concentration is greater than the first concentration threshold.

[0144] Optionally, after the processor controls the separation component according to the target rotation angle to adjust the cavity space of the first sub-inlet air cavity and the second sub-inlet air cavity, the method for controlling the fresh air module further includes: during the operation of the fresh air module, the processor obtains a target parameter. In the case that the target parameter meets a condensation formation condition, the processor controls the separation component to rotate to reduce the amount of fresh air. In the case that the target parameter meets the condensation formation condition, it indicates that condensation is about to be formed or has been formed. Controlling the separation component to rotate to reduce the amount of fresh air can reduce the proportion of outdoor fresh air in the mixed air of the fresh air module, improve the temperature of the mixed air, thereby achieving the effect of preventing condensation, and further reducing the risk of water blowing.

[0145] Optionally, the target parameter includes the internal temperature of the fresh air module. The condensation formation condition includes: the internal temperature of the fresh air module is less than or equal to a first temperature threshold. Optionally, the determination method of the first temperature threshold includes: the processor obtains the internal humidity of the fresh air module, and determines the first temperature threshold according to the internal humidity. Wherein, the processor determines the first humidity threshold according to the internal humidity, including: the processor calculates the dew point temperature according to the internal humidity, and determines the first temperature threshold according to the dew point temperature.

[0146] Optionally, the target parameter includes the outdoor environment temperature. The condensation formation condition includes: the outdoor environment temperature is less than or equal to an outdoor environment temperature threshold.

[0147] Optionally, in the case that the target parameter meets the condensation formation condition, the method for controlling the fresh air module further includes: the processor controls the impeller to reduce the rotating speed, and / or the processor controls the electric heating module to start heating. Wherein, the electric heating module is configured to electrically heat the outdoor fresh air entering the fresh air module.

[0148] In combination Figure 9 As shown in the figure, the embodiment of the present disclosure provides another method for controlling a fresh air module, including:

[0149] S901, the processor obtains the volume of the space of the fresh air module, the indoor carbon dioxide concentration, and the outdoor carbon dioxide concentration.

[0150] S902, the processor determines the target fresh air amount required in the room according to the volume of the space, the indoor carbon dioxide concentration, and the outdoor carbon dioxide concentration.

[0151] S903, the processor determines a target rotation angle according to the target fresh air volume.

[0152] S904, the processor controls the partition component according to the target rotation angle to adjust the cavity space of the first and second sub-inlet air cavities.

[0153] In this way, the required fresh air volume in the room can be accurately calculated according to the volume of the space, the indoor carbon dioxide concentration and the outdoor carbon dioxide concentration, so as to ensure the accuracy of the target rotation angle.

[0154] Optionally, the processor determines the target fresh air volume required in the room according to the volume of the space, the indoor carbon dioxide concentration and the outdoor carbon dioxide concentration, comprising: the processor obtains a target carbon dioxide concentration, and calculates the fresh air volume required to reduce the current indoor carbon dioxide concentration to the target carbon dioxide concentration according to the volume of the space, the indoor carbon dioxide concentration and the outdoor carbon dioxide concentration.

[0155] The target carbon dioxide concentration can be directly set as a default value, such as 400ppm, 500ppm, 600ppm, etc. Alternatively, it can be obtained by the user directly through the input device. In other embodiments, the target carbon dioxide concentration can also be determined according to the user identity and the number of people in the current room according to the different target carbon dioxide concentration requirements of different users.

[0156] Optionally, the processor obtains the indoor carbon dioxide concentration, comprising: the processor obtains the carbon dioxide concentration every preset time interval, and determines the value closest to the current time as the indoor carbon dioxide concentration value.

[0157] Optionally, the processor determines the target fresh air volume required in the room according to the volume of the space, the indoor carbon dioxide concentration and the outdoor carbon dioxide concentration, comprising: the processor determines the relationship between the fresh air volume and the change of the indoor carbon dioxide concentration under the condition of the volume of the current space, the indoor carbon dioxide concentration and the outdoor carbon dioxide concentration; and determines the corresponding fresh air volume when the change of the indoor carbon dioxide concentration is the target carbon dioxide concentration as the target fresh air volume.

[0158] The change of the indoor carbon dioxide concentration with time is represented as:

[0159] V V C out dt+Q P dt-(V V +V N )Cdt=V r dC;

[0160] Wherein, V V is the fresh air volume of the fresh air module in operation; C outC0is the initial concentration of carbon dioxide; t is time; Q P is the emission rate of indoor pollutants, i.e., the rate of carbon dioxide exhaled by indoor users, which can be obtained according to the number of indoor users; V N is the amount of air naturally infiltrated; V r is the volume of the space acted on by the fresh air module.

[0161] After changing and deriving the above formula, the indoor carbon dioxide concentration is obtained as follows:

[0162]

[0163] wherein C0is the initial carbon dioxide concentration, λ is the air exchange rate when the fresh air module ventilates and the air naturally infiltrates, which can be determined by an empirical formula obtained through experiments; V is the total air volume of the room; λ t is the air exchange rate when the fresh air module acts, which can also be obtained through experimental simulation.

[0164] According to the above formula, the carbon dioxide concentration can be predicted, so as to determine the fresh air volume required to reduce the carbon dioxide to the target carbon dioxide concentration, which is recorded as the target fresh air volume.

[0165] In combination with Figure 10 , the embodiment of the present disclosure provides another method for controlling a fresh air module, which comprises the following steps.

[0166] S1001, a processor obtains a target fresh air volume required in a room.

[0167] S1002, the processor determines a target rotation angle according to the target fresh air volume.

[0168] S1003, the processor determines whether the target rotation angle is less than or equal to a maximum angle allowed for rotation of a partition component.

[0169] If yes, step S1004 is performed; if no, step S1005 is performed.

[0170] S1004, the processor controls the partition component according to the target rotation angle.

[0171] Here, the processor controls the partition component according to the target rotation angle, i.e., the processor controls the operation of a baffle driver to rotate a movable baffle by the target rotation angle.

[0172] S1005, the processor controls the partition component according to the target rotation angle and controls an impeller to increase the rotation speed.

[0173] Here, the processor controls the operation of the baffle driver, i.e., the processor controls the operation of the baffle driver to rotate the movable baffle to the maximum angle allowed for rotation.

[0174] According to different actual situations, there will be different fresh air demand, but in the actual structure, the partition component can only move within a certain range. Therefore, after determining the target rotation angle, the target rotation angle is further judged. If the target rotation angle is greater than the maximum angle of the allowed rotation, the impeller speed is increased to speed up the gas exchange process, thereby increasing the speed of fresh air replacement, reducing the carbon dioxide concentration in the room in a shorter time, and further optimizing the user experience.

[0175] During this process, considering that increasing the impeller speed will inevitably increase the noise, the position of the partition component is adjusted to meet the fresh air demand, and the impeller speed is increased when the demand cannot be met.

[0176] Optionally, the processor controls the impeller to increase the speed, including: the processor determines a speed increase amount according to the target rotation angle, and controls the impeller speed to increase by the speed increase amount.

[0177] Optionally, the processor determines the speed increase amount according to the target rotation angle, including: the processor determines the difference between the target rotation angle and the maximum angle of the allowed rotation, and determines the speed increase amount according to the difference. Wherein, the processor determines the speed increase amount according to the difference, including: the processor determines that the speed increase amount is positively correlated with the difference. In actual application, different gears can be set for the speed of the impeller. Each gear corresponds to a certain range of speed increase amount, the range to which the calculated speed increase amount belongs is determined, and then the required speed gear is determined. In this way, accurate control of the speed of the impeller can be achieved.
