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 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, and to reflect fresh outdoor air into the indoor environment to increase the oxygen content of indoor air and reduce the concentration of air pollutants. In this case, the "fresh air conditioner" product emerges as the times require. The fresh air conditioner increases components such as a fresh air module and a fresh air duct on the basis of a 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 a fixed middle partition plate. The middle 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. In the case of large indoor and outdoor temperature difference, condensation is easily generated in the internal air cavity of the fresh air module, causing water blowing phenomenon.

[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.

[0066] 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 achieve the functions of introducing outdoor fresh air alone, discharging indoor dirty air alone, and / or introducing outdoor fresh air and discharging indoor dirty air at the same time, thereby improving indoor air quality and enhancing environmental comfort.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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 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 in Figure 4b .

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] Specifically, in some optional embodiments, as shown in Figure 3b and 3d , the separation component is pivotally connected 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.

[0082] In this 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.

[0083] Here, the movable partition plate 181 is pivotally connected to 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 pivotally connected 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.

[0084] In an 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.

[0085] In this 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.

[0086] Optionally, the air inlet cavity 11 is configured in the form of a cavity with a circular or approximately circular overall outline, and the rotation axis of the movable partition 181 is arranged at the center of the air inlet cavity 11. In this way, the longitudinal two ends of the movable partition 181 respectively extend to the inner circumferential line of the air inlet cavity 11, and can be driven by the partition driver 182 to rotate along the circumferential direction of the air inlet cavity 11. Further optionally, the movable partition 181 is a straight plate or a non-straight plate. Optionally, the non-straight plate includes a curved shape, a broken line shape, or the like, or is in the form of a plate body spliced by one or more straight lines and / or one or more curved lines.

[0087] Optionally, the partition component further includes one or more static partitions, which can cooperate with the movable partition 181 to jointly define the sub-air inlet cavities and / or the rotation area of the movable partition 181.

[0088] Specifically, in combination with the drawings, Figure 3c As shown, the partition component includes a first static partition 183 and / or a second static partition 184. Optionally, the first static partition 183 is arranged on the side wall of the air inlet cavity 11 where the outdoor air inlet 114 and the indoor return air outlet 113 are located, and is extended and formed towards the inside of the air inlet cavity 11; the first static partition 183 can serve to separate the outdoor air inlet 114 and the indoor return air outlet 113, so as to limit the outdoor air inlet 114 within the spatial range of the first sub-air inlet cavity 115 and the indoor return air outlet 113 within the spatial range of the second sub-air inlet cavity 116. Further optionally, the second static partition 184 is arranged on the other side wall opposite to the side wall where the first static partition 183 is arranged, and is also extended and formed towards the inside of the wall of the air inlet cavity 11; the second static partition 184 can serve to separate the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116.

[0089] In the present embodiment, the first static partition 183 and the second static partition 184 are arranged in a spaced manner, and the rotation area of the movable partition 181 is located in the spacing space.

[0090] In this way, one side surface of the movable partition 181, one side surface of the first static partition 183, one side surface of the second static partition 184, and at least a part of the cavity wall of the air inlet cavity 11 jointly form the first sub-air inlet cavity 115. In addition, the other side surface of the movable partition 181, the other side surface of the first static partition 183, the other side surface of the second static partition 184, and at least another part of the cavity wall of the air inlet cavity 11 jointly form the second sub-air inlet cavity 116.

[0091] Optionally, in combination with the drawings, Figure 3cAs shown, the first static partition 183 includes a first straight plate segment 1831 and a first arc segment 1832. One longitudinal end of the first straight plate segment 1831 is fixedly connected to the second sidewall 1112, and the fixed position is located between the outdoor air vent 114 and the indoor return air vent 113. 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 to the extended end of the first straight plate segment 1831, and the other end is a free end. The first arc segment 1832 extends along the rotational outer circumference of the first outer plate end of the movable partition 181, and the first outer plate end of the movable partition 181 slidably abuts against the inner plate surface of the first arc segment 1832. Alternatively, the end of the first arc segment 1832 connected to the first straight plate segment 1831 can continue to extend along the rotational outer circumference direction to expand the rotational range of the first outer plate end.

[0092] Similarly, combination Figure 3c As shown, the second static baffle 184 includes a second straight section 1841 and a second arc section 1842. One longitudinal end of the first straight section 1841 is fixedly connected to the first sidewall 1111, and the other end extends towards the inside of the air inlet cavity 11. One end of the second arc section 1842 is fixedly connected to the extended end of the second straight section 1841, and the other end is a free end. The second arc section 1842 extends along the rotational outer circumference of the second outer plate end of the movable baffle 181, and the second outer plate end of the movable baffle 181 slidably abuts against the inner plate surface of the second arc section 1842. Alternatively, the end of the second arc section 1842 that connects to the second straight section 1841 can continue to extend along the rotational outer circumference direction to expand the rotational range of the second outer plate end.

[0093] Optionally, the arc lengths of the first arc segment 1832 and the second arc segment 1842 are substantially equal.

[0094] In this embodiment, the rotation range of the movable partition 181 is limited to the angle range corresponding to the shortest arc length of the first arc segment 1832 and the second arc segment 1842. This ensures that the first outer plate end of the movable partition 181 can always abut against the first arc segment 1832 and the second outer plate end can always abut against the second arc segment 1842 during the rotation process.

[0095] In some embodiments, the fresh air module further includes an air inlet group, which includes a first air inlet and a second air inlet.

[0096] The first air inlet is arranged on the cavity wall corresponding to the first sub-air inlet cavity 115, and is used to introduce outdoor fresh air into the first sub-air inlet cavity 115. Optionally, the first air inlet is the outdoor air inlet 114 in the foregoing embodiment, which is arranged on the second side wall 1112 of the air inlet cavity 11. The second air inlet is arranged on the cavity wall corresponding to the second sub-air inlet cavity 116, and is used to introduce indoor dirty air into the second sub-air inlet cavity 116. Optionally, the second air inlet is the indoor return air inlet 113 in the foregoing embodiment, which is arranged on the second side wall 1112 of the air inlet cavity 11.

[0097] In still some embodiments, the fresh air module further comprises an air outlet group, and the air outlet group comprises a first air outlet and a second air outlet.

[0098] Optionally, the air outlet group is arranged in the fan cavity 12 of the fresh air module, and the first air outlet corresponds to the first sub-air inlet cavity 115, and the second air outlet corresponds to the second sub-air inlet cavity 116. When the fan cavity is rotated downward, at least part of the airflow of the first sub-air inlet cavity 115 is diverted to flow toward the first air outlet, and at least part of the airflow of the second sub-air inlet cavity 116 is diverted to flow toward the second air outlet. In an embodiment, the first air outlet is used to output outdoor fresh air from the first sub-air inlet cavity 115 to the indoor side, and the second air outlet is used to output indoor dirty air from the second sub-air inlet cavity 116 to the outdoor side, or to output indoor dirty air from the second sub-air inlet cavity 116 to the indoor side after filtering.

[0099] Optionally, the first air outlet is a first volute air outlet, and the second air outlet is a second volute air outlet.

[0100] Further optionally, the extension coverage of the first circular arc segment 1832 and the second circular arc segment 1842 is limited to: when the movable partition plate 181 is rotated to a first position, the first position is that the first outer plate end of the movable partition plate 181 is located at the distal end of the first circular arc segment 1832 or the second outer plate end of the movable partition plate 181 is located at the distal end of the second circular arc segment 1842, as shown in FIG. 18B, at least part of the cavity space of the second sub-air inlet cavity 116 corresponds to the upstream of the air path of the first volute air outlet, and at least part of the cavity space of the first sub-air inlet cavity 115 corresponds to the upstream of the air path of the second volute air outlet, so that part of the fresh air flow of the first sub-air inlet cavity 115 is diverted to the second volute air outlet, and then discharged to the outdoor side through the second volute air outlet, as shown in FIG. 18C, the fresh air flow corresponding to the C1 region; and part of the dirty air flow of the second sub-air inlet cavity 116 is diverted to the first volute air outlet, as shown in FIG. 18D, the dirty air flow corresponding to the C2 region. Figure 3e Figure 3e Figure 3e

[0101] ​​​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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] In 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] In this way, when the movable partition moves in the air inlet cavity in the transverse direction, 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.

[0112] 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.

[0113] 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.

[0114] Optionally, the form of the partition plate shown in the foregoing embodiments for partitioning the inlet passage 1223 of the impeller 122 can also be applied to the partition component in this embodiment, so that the partition component not only dynamically adjusts the sub-inlet cavity space in the inlet cavity 11 during operation, but also dynamically adjusts the passage space of the inlet passage 1223 in the fan cavity 12, so as to enhance the effect of distributing the airflows from different sources.

[0115] In combination with the foregoing embodiments, the first partition plate 191 of the partition component is arranged in the inlet passage 1223 of the impeller 122, and the second partition plate 192 of the partition component is the movable partition plate 181 in this embodiment. The first partition plate 191 is fixed on the movable partition plate 181 and can move together with the movable partition plate 181, as shown in Figure 3g Here, the first partition plate 191 is applied to the movable partition plate 181 scheme that moves in a rotating manner relative to the inlet cavity 11.

[0116] Optionally, the partition plate driver 182 can be in driving connection with the first partition plate 191 or the second partition plate 192, for driving the first partition plate 191 to rotate relative to the fan cavity and the second partition plate 192 to rotate relative to the inlet cavity 11, so as to change the partition position of the first partition plate 191 relative to the inlet passage 1223 and the partition position of the second partition plate 192 (movable partition plate 181) relative to the inlet cavity 11.

[0117] In some optional embodiments, at least part of the body of the impeller driver 126 is located in the inlet passage 1223 of the impeller 122, and accordingly, the first partition plate 191 is formed with a recess 1911 for avoiding the impeller driver 126, so as to avoid the first partition plate 191 from interfering with the impeller driver 126 during rotation, as shown in Figure 3h Here, the recess 1911 is arranged in spaced manner relative to the impeller driver 126, and the gap between the edge of the recess and the impeller driver 126 is minimized under the premise of avoiding contact, so as to improve the air tightness and reduce the mixing of the airflows in the two inlet regions in the inlet passage 1223 through the gap.

[0118] Here, the recess 1911 is arranged in spaced manner relative to the impeller driver 126, and the gap between the edge of the recess and the impeller driver 126 is minimized under the premise of avoiding contact, so as to improve the air tightness and reduce the mixing of the airflows in the two inlet regions in the inlet passage 1223 through the gap.

[0119] The following describes several air exchange modes of the fresh air module 1 in combination with the form of the fresh air module 1 shown in the foregoing embodiments. (Here, the outdoor fresh air is indicated by solid arrows, and the indoor dirty air is indicated by dashed arrows.)

[0120] In combination with 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.

[0121] 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.

[0122] In this way, when the impeller 122 rotates, a negative pressure suction force is generated on the side of the air inlet cavity 11, 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 . 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 .

[0123] 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.

[0124] 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 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.

[0125] In this way, when the impeller 122 rotates, a negative pressure suction force is generated on the side of the air inlet chamber 11, attracting outdoor fresh air and indoor dirty air on the indoor side to flow into the air inlet chamber 11 at the same time. Among them, the outdoor fresh air flow path is that the outdoor fresh air is transported to the first indoor air outlet 51 in sequence 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. 1B. Figure 5a and 5c In this way, when the impeller 122 rotates, a negative pressure suction force is generated on the side of the air inlet chamber 11, attracting outdoor fresh air and indoor dirty air on the indoor side to flow into the air inlet chamber 11 at the same time. Among them, the outdoor fresh air flow path is that the outdoor fresh air is transported to the first indoor air outlet 51 in sequence 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. 1B. Figure 5b and 5c In this way, when the impeller 122 rotates, a negative pressure suction force is generated on the side of the air inlet chamber 11, attracting outdoor fresh air and indoor dirty air on the indoor side to flow into the air inlet chamber 11 at the same time. Among them, the outdoor fresh air flow path is that the outdoor fresh air is transported to the first indoor air outlet 51 in sequence 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. 1B.

[0126] In combination with Figures 6a to 6d Further alternatively, 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. The fresh air module 1 does not transport outdoor fresh air to the indoor side in this mode. This mode can be applied to the case where the outdoor environment air quality is also poor, such as smog weather.

[0127] 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 of the air outlet switching mechanism is located in the first rotating position or the second rotating position.

[0128] 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 housing 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 .

[0129] 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 in 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 in 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 .

[0130] Figure 7 A method for controlling a fresh air module is provided, which is applied to the fresh air module described above.

[0131] As shown in Figure 7 , the method for controlling the fresh air module comprises the following steps.

[0132] S701, during operation of the fresh air module, a processor obtains a target parameter;

[0133] S702, in the case where the target parameter meets a condensation formation condition, the processor controls a partition component to rotate to reduce a fresh air amount.

[0134] The method for controlling the fresh air module provided by the embodiments of the present disclosure sets the partition component in the air inlet cavity in a movable manner. During operation of the fresh air module, the target parameter is detected to determine whether the condensation formation condition is met. If the condensation formation condition is met, it means that condensation is about to be formed or has been formed. The partition component is controlled to rotate to reduce the fresh air amount, thereby reducing the proportion of outdoor fresh air in the mixed air of the fresh air module and improving the temperature of the mixed air, thereby achieving the effect of preventing condensation and reducing the risk of water blowing phenomenon.

[0135] Optionally, the target parameter comprises an internal temperature of the fresh air module. The condensation formation condition comprises that the internal temperature of the fresh air module is less than or equal to a first temperature threshold. If the internal temperature of the fresh air module is less than or equal to the first temperature threshold, it indicates that the temperature is too low, and the possibility of condensation is relatively large, and thus it is determined that the condensation degree of the condensation is about to be formed or has been formed. In actual application, a second temperature threshold or more thresholds can be set to further refine the condensation degree of the condensation, so as to further improve the accuracy of the control of the partition component.

[0136] The internal temperature of the fresh air module is detected by a temperature sensor arranged in the fresh air module. For example, the temperature sensor is arranged in the first air outlet pipe 13 (in combination with the description of the temperature sensor in the first air outlet pipe 13, which will be described below). Figure 1 In this way, the real-time temperature can be accurately detected, and the accuracy of temperature detection can be ensured.

[0137] Optionally, the first temperature threshold is determined by the processor in the following manner: the processor obtains the internal humidity of the fresh air module, and determines the first temperature threshold according to the internal humidity. The internal humidity of the fresh air module is detected by a humidity sensor arranged in the fresh air module. For example, the humidity sensor is arranged in the first air outlet pipe 13. In this way, the real-time humidity can be accurately detected, and the accuracy of humidity detection can be ensured.

[0138] Optionally, the processor determines the first temperature threshold according to the internal humidity in the following manner: the processor calculates a dew point temperature according to the internal humidity, and determines the first temperature threshold according to the dew point temperature. In this way, whether the temperature reaches the dew point temperature can reflect whether the condensation is likely to be formed, and thus determining the first temperature threshold according to the dew point temperature to judge the condensation degree of the condensation is conducive to improving the accuracy of the condensation degree judgment.

[0139] In other embodiments, the first temperature threshold is determined according to the dew point temperature in the following manner: the processor determines the first temperature threshold as the sum of the dew point temperature and a temperature correction value. The temperature correction value is a positive number. In this way, the current situation that is likely to cause condensation can be determined earlier, so that the condensation can be effectively prevented.

[0140] In other embodiments, the first temperature threshold is determined according to the dew point temperature in the following manner: the processor determines the first temperature threshold as the difference between the dew point temperature and a temperature correction value. The temperature correction value is a negative number. In this way, the partition component can be adjusted before the condensation is formed, so that unnecessary sacrifice of fresh air volume can be avoided.

[0141] In other embodiments, the first temperature threshold is determined according to the dew point temperature in the following manner: the processor determines the first temperature threshold as the difference between the dew point temperature and a temperature correction value. The temperature correction value is a negative number. In this way, the partition component can be adjusted before the condensation is formed, so that unnecessary sacrifice of fresh air volume can be avoided.

[0142] Optionally, the first temperature threshold is determined by determining a correspondence between the temperature inside the fresh air module and the degree of condensation of the condensation through historical data, and determining the first temperature threshold according to the correspondence. For example, the temperature inside the fresh air module when the condensation just starts to form each time is determined, and the average, median or mode of the obtained multiple internal temperatures is taken as the first temperature threshold. In this way, a more accurate first temperature threshold can be determined according to the historical data, which is beneficial to improving the accuracy of the condensation formation condition judgment and the subsequent control of the partition component.

[0143] In other embodiments, the target parameter includes an outdoor environment temperature. The condensation formation condition includes that the outdoor environment temperature is lower than an environment temperature threshold.

[0144] In other embodiments, the target parameter includes image information inside the fresh air module. The condensation formation condition includes that the image information indicates that the condensation is generated inside the fresh air module. In this way, the real-time formation of the condensation can be determined intuitively and accurately.

[0145] Optionally, the processor controls the rotation of the partition component, including: the processor controls the operation of the baffle driver to control the baffle to rotate by a unit angle every unit time until the surface of the fresh air module is not prone to form condensation.

[0146] Optionally, the processor controls the rotation of the partition component, including: the processor controls the operation of the baffle driver to rotate the baffle by a target angle.

[0147] The target angle can be directly obtained by the user setting.

[0148] In other embodiments, the target angle is determined by the processor according to the target parameter.

[0149] Optionally, when the target parameter is the temperature inside the fresh air module, the processor determines the target angle according to the target parameter, including: the processor determines that the target angle is negatively correlated with the internal temperature. That is, the lower the internal temperature, the larger the target angle. In actual application, a mapping relationship between the temperature range of the internal temperature and the target angle can be set, and the target angle is determined according to the current internal temperature according to the mapping relationship.

[0150] Optionally, when the target parameter is the outdoor environment temperature: the processor determines that the target angle is negatively correlated with the outdoor environment temperature. That is, the lower the outdoor environment temperature, the larger the target angle. In actual application, a mapping relationship between the outdoor environment temperature and the target angle can be set, and the target angle is determined according to the outdoor environment temperature in the actual operation process according to the mapping relationship.

[0151] Optionally, in the case that the target parameter meets the dew formation condition, the method for controlling the fresh air module further comprises: the processor controls the impeller to reduce the rotating speed. In this way, the dew formation process is slowed down.

[0152] Optionally, after the processor controls the partition component to rotate, the method for controlling the fresh air module comprises: the target parameter is obtained again after a first preset time length. If the dew formation condition is still met, the processor controls the impeller to reduce the rotating speed. In this way, the unnecessary reduction of the rotating speed of the impeller does not affect the fresh air replacement process.

[0153] Optionally, the fresh air module further comprises: an electric heating module configured to electrically heat the outdoor fresh air entering the fresh air module.

[0154] Optionally, in the case that the target parameter meets the dew formation condition, the method for controlling the fresh air module further comprises: the processor controls the electric heating module to start heating. In this way, the heating of the fresh air entering the fresh air module can avoid the over-cooled fresh air from causing dew.

[0155] Optionally, after the processor controls the partition component to rotate, the method for controlling the fresh air module comprises: the target parameter is obtained again after a second preset time length. If the dew formation condition is still met, the processor controls the electric heating module to start heating.

[0156] In combination with Figure 8 The embodiments of the present disclosure provide another method for controlling a fresh air module, which comprises:

[0157] S801, a processor obtains a target parameter during the operation of a fresh air module.

[0158] S802, in the case that the target parameter meets a dew formation condition, the processor determines an initial target angle according to the target parameter.

[0159] S803, the processor determines whether the initial target angle is less than or equal to a maximum angle allowed for the rotation of a movable partition.

[0160] If yes, step S804 is performed; if no, step S805 is performed.

[0161] S804, the processor determines the target angle as the initial target angle, and controls a partition driver to operate so as to rotate the movable partition by the target angle.

[0162] S805, the processor determines the target angle as the maximum angle allowed for the rotation, controls the partition driver to operate so as to rotate the movable partition by the target angle, and controls an impeller to reduce the rotating speed.

[0163] In actual application, different situations can exist, but the angle of rotation of the movable partition is limited by the structure. Therefore, after the initial target angle is calculated, it is determined according to the maximum angle of rotation allowed by the movable partition. If the angle of rotation allowed is less than the initial target angle, it indicates that the rotation of the partition alone cannot achieve anti-condensation, and at this time the control of the impeller reduces the speed to further prevent condensation.

[0164] The processor controlling the impeller to reduce the speed includes that the processor calculates a difference between the initial target angle and the maximum angle of rotation allowed, and controls the impeller to reduce the speed according to the difference.

[0165] Specifically, the greater the difference is, the lower the speed of the impeller is. In this way, the speed of the impeller can be accurately controlled to optimize the anti-condensation effect.

[0166] In combination with Figure 9 The embodiment of the present disclosure provides another method for controlling a fresh air module, which includes the following steps.

[0167] S901, a processor obtains a target fresh air amount required in a room.

[0168] S902, the processor determines a target rotation angle according to the target fresh air amount.

[0169] S903, the processor controls a partition component according to the target rotation angle to adjust the cavity space of the first and second sub-inlet air cavities.

[0170] S904, the processor obtains a target parameter during operation of the fresh air module.

[0171] S905, in the case that the target parameter meets the condensation formation condition, the processor controls the partition component to rotate to reduce the fresh air amount.

[0172] In this way, the target rotation angle is first determined according to the target fresh air amount required in the room, and then the formation of condensation is determined according to the target parameter during operation, so as to adjust the partition component. In the case that the target parameter meets the condensation formation condition, it indicates that condensation will be generated or has been generated, and at this time the anti-condensation is given priority to at the expense of a certain fresh air amount. The indoor fresh air amount demand is met to the greatest extent while the water blowing phenomenon is avoided.

[0173] Optionally, the processor obtains the target fresh air amount required in the room, including that the processor obtains the volume of the space acted on by the fresh air module, the indoor carbon dioxide concentration, the outdoor carbon dioxide concentration, and 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.

[0174] 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, including: 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.

[0175] 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, including: 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.

[0176] Optionally, the processor determines the target rotation angle according to the target fresh air volume, including: the processor determines the target rotation angle according to the corresponding relationship between the fresh air volume and the rotation angle, and the target fresh air volume.

[0177] Optionally, the processor determines the target rotation angle according to the target fresh air volume, including: the processor determines the target rotation angle according to the corresponding relationship between the fresh air volume and the rotation angle, and the target fresh air volume.

[0178] Specifically, the fresh air module is simulated, and the condition that the partition component is in different positions is simulated. The corresponding fresh air volume when the partition component is in different positions is recorded, 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, and the corresponding relationship between the fresh air volume and the rotation angle is further established.

[0179] According to the 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.

[0180] In combination with FIGS. 1-3, Figure 3e and Figure 3f As shown, the first position is the initial position. With the continuous movement of the partition plate from the first position to the second position, the fresh air volume from the outdoor to the indoor is continuously increased, which can reduce the indoor carbon dioxide concentration faster. That is, the greater the rotation angle, the greater the fresh air volume.

[0181] In the case that the target parameter meets the condensation formation condition, the processor controls the rotation of the partition component to reduce the fresh air volume, that is, controls the partition plate to move from the second position to the first position.

[0182] Optionally, the processor controls the separation component according to the target rotation angle, and further comprising: the processor obtains the indoor carbon dioxide concentration, and controls the impeller to increase the rotation speed when the carbon dioxide concentration is greater than the first concentration threshold.
