Description

Technical Field

[0001] The present application relates to the field of indoor fresh air exchange technology, for example, to a method and device for controlling a fresh air module, a fresh air module and air conditioning equipment. Background Art

[0002] As people pay more and more attention to air quality issues, users have higher and higher requirements for air quality in daily living rooms such as living rooms and bedrooms. There are many factors that lead to the decline of indoor air quality, such as formaldehyde, benzene, and ammonia air pollutants volatilized from indoor decoration materials, or the indoor air is not circulated due to the doors and windows being closed at night, which will accumulate a large amount of harmful gases such as carbon dioxide and formaldehyde. Such air quality problems will more or less affect the health of users in the room, such as inducing users to feel chest tightness, shortness of breath, dry mouth, and difficulty breathing.

[0003] One of the effective ways to solve the above air quality problems is to maintain ventilation between indoor and outdoor areas, and let fresh air from the outdoor side enter the indoor environment to increase the oxygen content of indoor air and reduce the concentration of air pollutants. In this case, the "fresh air air conditioner" product came into being. Fresh air air conditioners are based on traditional air conditioner models and add fresh air modules, fresh air ducts and other components. The fan is used to draw fresh air from the outdoor side 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 there are at least the following problems in the related art:

[0005] In the related product design, a fresh air module solution with dual functions of outdoor fresh air and indoor exhaust is also provided. The internal air cavity of the fresh air module is provided with a fixed middle partition, which can be used to separate the air cavity into an outdoor fresh air cavity and an indoor dirty air cavity, so that the outdoor fresh air can be introduced into the indoor environment through the outdoor fresh air cavity, and the indoor dirty air can be discharged to the outdoor environment through the indoor dirty air cavity. In the case of a large temperature difference between indoor and outdoor, condensation is easy to occur inside the fresh air module, causing water blowing.

[0066] The present application provides a fresh air module 1, which can be applied to air conditioning equipment such as air conditioners (such as wall-mounted air conditioners), fresh air fans, humidifiers, etc., so as to controllably realize the functions of separately introducing outdoor fresh air, separately exhausting indoor polluted air, and / or simultaneously introducing outdoor fresh air and exhausting indoor polluted air, thereby improving indoor air quality and enhancing environmental comfort.

[0067] like Figure 1 , 1aAs shown, the fresh air module 1 mainly includes components such as a module housing 10, a fresh air duct 20 and an air outlet switching unit 30. The module housing 10 is internally constructed with an air cavity that limits the airflow path, and can be used as a space for accommodating components such as an air filter element 14 and an impeller 122. Here, the module housing 10 is provided with an indoor air outlet for communicating with the indoor side, and an outdoor air outlet 114 for communicating with the outdoor side. The indoor air outlet includes an indoor air outlet and / or an indoor return air outlet 113, the indoor air outlet is used as an air outlet for the fresh air module 1 to supply air to the indoor side, and the indoor return air outlet 113 is used as an air outlet for air to flow back from the indoor side to the fresh air module 1; the outdoor air outlet 114 is used as an air outlet for the fresh air module 1 to exhaust air to the outdoor side or for the outdoor side to transport 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 exhausting indoor polluted air. The fresh air duct 20 is connected to the air cavity of the module housing 10, thereby jointly defining an outdoor fresh air introduction path and / or an indoor polluted air exhaust path. The air outlet switching unit 30 is provided on the air outlet side of the module housing 10, and is used to define the air outlet direction of at least part of the airflow flowing through the module housing 10, and the at least part of the airflow includes outdoor fresh air or indoor polluted air, and the air outlet direction includes flowing to the indoor side or the outdoor side, thereby realizing the functions of introducing outdoor fresh air and / or exhausting outdoor polluted air.

[0068] In some optional embodiments, combined with Figure 2 As shown, the air cavity of the module housing 10 includes an air inlet cavity 11 and a fan cavity 12, and the air inlet cavity 11 is connected with the fan cavity 12, and air can flow between the air inlet cavity 11 and the fan cavity 12. Among them, the air inlet cavity 11 can be used to accommodate components such as partition components and air filter elements 14, and the air inlet cavity 11 is connected with one or more of the indoor air outlet and the outdoor air outlet 114. The fan cavity 12 can be used to accommodate components such as an impeller 122, and the fan cavity 12 is connected with one or more of the indoor air outlet and the outdoor air outlet 114.

[0069] Optionally, the air inlet cavity 11 is located upstream of the wind path relative to the fan cavity 12, that is, the fan cavity 12 is located on the wind outlet side of the air inlet cavity 11, so that the flow direction of air from the air inlet cavity 11 to the fan cavity 12 is defined in the module housing 10. Alternatively, the air inlet cavity 11 is located downstream of the wind path relative to the fan cavity 12, that is, the air inlet cavity 11 is located on the wind outlet side of the fan cavity 12, so that the flow direction of air from the fan cavity 12 to the air inlet cavity 11 is defined in the module housing 10. Hereinafter, the former "the air inlet cavity 11 is located upstream of the wind path of the fan cavity 12" structure is mainly used as an example for explanation.

[0070] In some optional embodiments, the module housing 10 further includes a first air outlet duct 13, which is connected to the module housing 10 and is located at the air outlet side of the air inlet cavity 11 (fan cavity 12), and is used to construct a first indoor air outlet 51 as an air outlet path, and the air outlet airflow of the air inlet cavity 11 (fan cavity 12) can be transported to the external environment through the first air outlet duct 13. Similarly, the module housing 10 further includes a second air outlet duct, which is connected to the module housing 10 and is located at the air outlet side of the air inlet cavity 11 (fan cavity 12), and is used to construct a second indoor air outlet 52 as an air outlet path, and the air outlet airflow of the air inlet cavity 11 (fan cavity 12) can be transported to the external environment through the second air outlet duct.

[0071] In the above embodiment, the actual air supply direction can be adjusted by changing the extension direction of the first air outlet duct 13 (and the second air outlet duct) or the direction of the air outlet end of the duct. For example, in the above embodiment, the first indoor air outlet 51 is used to supply air to the front and upper direction, and the corresponding first air outlet duct 13 can be extended and formed in the front and upper direction, and its air outlet end faces the front and upper direction.

[0072] Here, the fan chamber 12 is arranged on the air outlet side of the air inlet chamber 11, and the first indoor air outlet 51 and the second indoor air outlet 52 are respectively connected to the fan chamber 12 through the fan chamber 12. In the embodiment, 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 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. When the impeller 122 rotates downward in the fan chamber 12, the air located upstream of the first indoor air outlet 51 will preferentially and concentratedly flow to the first indoor air outlet 51, as shown in FIG. Figure 4b and the air located upstream of the second indoor air outlet 52 will preferentially flow to the second indoor air outlet 52, such as Figure 4b The airflow is shown by the dashed arrows.

[0073] In some embodiments, in combination Figure 4b As shown, 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 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 airflow in the fan volute is transported to the first indoor air outlet 51 through the first volute air outlet. The second volute air outlet is provided at the bottom 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 airflow in the fan volute is transported to the second indoor air outlet 52 through the second volute air outlet.

[0074] In some embodiments, in combination Figures 3a to 3hAs shown, the air inlet chamber 11 includes a first sub-air inlet chamber 115 and a second sub-air inlet chamber 116, and the two are separated from each other. The first sub-air inlet chamber 115 and the second sub-air inlet chamber 116 respectively form a relatively independent air path. The air flowing into the air inlet chamber 11 is diverted to the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116, and continues to be transported to the fan chamber 12 along their respective air paths.

[0075] Optionally, a partition component is provided in the air inlet chamber 11 , and the partition component is used to divide the air inlet chamber 11 into a first sub-air inlet chamber 115 and a second sub-air inlet chamber 116 .

[0076] Optionally, the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116 can respectively circulate air from the same wind source. For example, the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116 are simultaneously used to transport outdoor fresh air from the outdoor side, or are simultaneously used to transport indoor polluted air from the indoor side.

[0077] Alternatively, the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116 can circulate air from different wind sources, for example, one of the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116 is used to convey outdoor fresh air from the outdoor side, and the other is used to convey indoor polluted air from the indoor side. Here, the partition component can at least be used to separate the air paths when the two sub-air inlet chambers 11 convey air from different wind sources, thereby blocking or slowing down the mixing of air in different clean states.

[0078] In some embodiments, in combination Figure 3b As shown, the partition component is movably disposed in the air inlet cavity 11 of the module housing 10, and its relative position with the air inlet cavity 11 can be controlled to adjust 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 disposes the partition component in the air inlet cavity 11, so that during the movement of the partition component, the cavity space of the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116 formed by the partition component can be changed, thereby achieving the effect of adjusting the fresh air intake and the dirty air exhaust volume.

[0079] Optionally, the partition component can adjust its relative position to the air inlet cavity 11 by rotating, sliding, etc. relative to the air inlet cavity 11.

[0080] Here, the partition component can separate the air outlet of the air inlet chamber 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 chamber 115 and the second sub-air inlet chamber 116 respectively, so as to serve as the path for the airflow of each of the two sub-air inlet chambers to be output to the fan chamber 12. In this way, during the operation of the partition component rotating, sliding, etc. relative to the air inlet chamber 11, the relative position of the partition component and the air outlet 112 of the air inlet chamber can be changed, so that the position of the separation boundary of the partition component for the first sub-air outlet and the second sub-air outlet is changed, thereby achieving the effect of changing the outdoor fresh air volume of the first sub-air inlet chamber 115 and / or the indoor polluted air volume of the second sub-air inlet chamber 116.

[0081] Specifically, in some optional embodiments, such as Figure 3b and 3d As shown, the partition component is pivotally connected to the air inlet cavity 11 , so that the partition component can rotate relative to the air inlet cavity 11 , thereby achieving the purpose of adjusting the relative position between the partition component and the air inlet cavity 11 .

[0082] In this embodiment, the partition component includes a movable partition 181 and a partition driver 182 . The partition driver 182 can drive the movable partition 181 to rotate in the air inlet chamber 11 .

[0083] Here, the movable partition 181 is pivoted in the air inlet cavity 11, and its rotation plane is parallel to the wall surface of the air outlet cavity wall. Optionally, the movable partition 181 is pivoted to another cavity wall of the air inlet cavity 11 opposite to the air outlet cavity wall, that is, the outer cavity wall 115 in the above embodiment, and the outer cavity wall is provided with a through hole for the motor shaft to penetrate. The partition driver 182 includes a partition driving motor and a motor shaft, such as Figure 3d As shown, the partition drive motor is fixed on the outer wall surface of the outer cavity wall, and its motor shaft extends into the air inlet cavity 11 through the above-mentioned through hole, and is fixedly connected to the movable partition 181, so that the partition drive motor can drive the movable partition 181 to rotate by rotating the motor.

[0084] In an embodiment, the partition drive motor is a bidirectional rotating motor type, so as to selectively drive the partition 181 to rotate in a clockwise direction or a counterclockwise direction.

[0085] In this embodiment, similar to the partition plates shown in the previous embodiments, the movable partition plate 181 and at least a portion of the cavity wall of the air inlet cavity 11 are surrounded to form a first sub-air inlet cavity 115, and are surrounded to form a second sub-air inlet cavity 116 with at least another portion of the cavity wall of the air inlet cavity 11. In this way, when the movable partition plate 181 rotates around the axial direction 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 by it can be changed.

[0086] Optionally, the air inlet chamber 11 is constructed as a cavity with an overall outer contour that is circular or approximately circular, and the rotation axis of the movable baffle 181 is set at the center of the air inlet chamber 11. In this way, the longitudinal ends of the movable baffle 181 extend to the inner circumference of the air inlet chamber 11 respectively, and can be driven by the baffle driver 182 to rotate along the circumferential direction of the air inlet chamber 11. In another option, the movable baffle 181 is a linear plate or a non-linear plate. Optionally, the non-linear plate includes a curved shape, a broken line shape, etc., or a plate body formed by splicing multiple sections of one or more straight lines, and / or one or more curved shapes.

[0087] Optionally, the partition component also includes one or more static partitions, which can cooperate with the dynamic partition 181 to jointly define the rotation area where each sub-air inlet chamber and / or the dynamic partition 181 is located.

[0088] Specifically, combined 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 chamber 11 where the outdoor air outlet 114 and the indoor return air outlet 113 are located, and is extended to the inner side of the air inlet chamber 11 to be formed; the first static partition 183 can play the role of separating the outdoor air outlet 114 and the indoor return air outlet 113, so as to limit the outdoor air outlet 114 to the spatial range of the first sub-air inlet chamber 115 and the indoor return air outlet 113 to the spatial range of the second sub-air inlet chamber 116. Another option is that the second static partition 184 is arranged on the other side wall opposite to the side wall where the first static partition 183 is located, and is also extended to the inner side of the wall of the air inlet chamber 11 to be formed; the second static partition 184 can play the role of separating the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116.

[0089] In this embodiment, the first static partition plate 183 and the second static partition plate 184 are spaced apart, and the rotation area of ​​the dynamic partition plate 181 is located in the spaced apart space.

[0090] In this way, one side of the moving baffle 181, one side of the first static baffle 183, one side of the second static baffle 184, and at least a portion of the cavity wall of the air inlet cavity 11 are collectively formed to form a first sub-air inlet cavity 115. And, the other side of the moving baffle 181, the other side of the first static baffle 183, the other side of the second static baffle 184, and at least another portion of the cavity wall of the air inlet cavity 11 are collectively formed to form a second sub-air inlet cavity 116.

[0091] Optionally, combined Figure 3cAs shown, the first static partition 183 includes a first straight plate segment 1831 and a first circular arc segment 1832. Among them, one longitudinal end of the first straight plate segment 1831 is fixedly connected to the second side wall 1112, and the fixed position is located between the outdoor air outlet 114 and the indoor return air outlet 113, and the other end extends toward the inner side of the air inlet chamber 11; one end of the first circular 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 circular arc segment 1832 is integrally extended and formed along the rotation outer circumference of the first outer plate end of the moving partition 181, and the first outer plate end of the moving partition 181 can be slidably abutted against the inner plate surface of the first circular arc segment 1832. Alternatively, the end of the first circular arc segment 1832 connected to the first straight plate segment 1831 can continue to extend along the rotation outer circumference to expand the rotation range of the first outer plate end.

[0092] Similar, combined Figure 3c As shown, the second static partition 184 includes a second straight plate segment 1841 and a second arc segment 1842. Among them, one longitudinal end of the first straight plate segment 1831 is fixedly connected to the first side wall 1111, and the other end extends toward the inner side of the air inlet cavity 11; one end of the second arc segment 1842 is fixedly connected to the extended end of the second straight plate segment 1841, and the other end is a free end. The second arc segment 1842 is integrally extended and formed along the rotational outer circumference of the second outer plate end of the moving partition 181, and the second outer plate end of the moving partition 181 can be slidably abutted against the inner plate surface of the second arc segment 1842. Alternatively, the end of the second arc segment 1842 connected to the second straight plate segment 1841 can continue to extend along the rotational outer circumference to expand the rotation 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 plate 181 is limited to the angle range corresponding to the shortest arc segment of 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 partition plate 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, and the air inlet group includes a first air inlet and a second air inlet.

[0096] Among them, the first air inlet is opened on the cavity wall corresponding to the first sub-air inlet cavity 115, which 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 above embodiment, which is opened on the second side wall 1112 of the air inlet cavity 11. The second air inlet is opened on the cavity wall corresponding to the second sub-air inlet cavity 116, which is used to introduce indoor polluted air into the second sub-air inlet cavity 116; optionally, the second air inlet is the indoor return air inlet 113 in the above embodiment, which is opened on the second side wall 1112 of the air inlet cavity 11.

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

[0098] Optionally, the air outlet group is provided in the fan chamber 12 of the fresh air module, and the first air outlet corresponds to the first sub-air inlet chamber 115, and the second air outlet corresponds to the second sub-air inlet chamber 116. When the fan chamber rotates downward, at least part of the airflow of the first sub-air inlet chamber 115 flows toward the first air outlet, and at least part of the airflow of the second sub-air inlet chamber 116 flows 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 chamber 115 to the indoor side; the second air outlet is used to discharge indoor polluted air from the second sub-air inlet chamber 116 to the outdoor side, or, to filter the indoor polluted air and output it from the second sub-air inlet chamber 116 to the indoor side.

[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 extended coverage range of the first arc segment 1832 and the second arc segment 1842 is defined as: when the movable partition 181 rotates to the 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, such as Figure 3e As shown, at least part of the cavity space of the second sub-air inlet cavity 116 corresponds to the upstream of the wind 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 wind path of the second volute air outlet, so that part of the fresh air flow of the first sub-air inlet cavity 115 will be diverted to the second volute air outlet, and then discharged to the outdoor side through the second volute air outlet, as shown in FIG. Figure 3e and part of the polluted air flow of the second sub-air inlet chamber 116 will be diverted to the first volute air outlet, such as Figure 3e The dirty air flow corresponding to the C2 area.

[0101] Therefore, compared with the fixed partition form in the previous embodiment, part of the indoor dirty air replaces part of the outdoor fresh air and is output to the indoor side, and this part of the replaced outdoor fresh air is re-exhausted to the outdoor side. Therefore, when the movable partition 181 is in the first position, the amount of outdoor fresh air output to the indoor side is reduced.

[0102] Further optionally, the extended coverage range of the first arc segment 1832 and the second arc segment 1842 is defined as: when the movable partition 181 rotates to the second position, the first position is that the first outer plate end of the movable partition 181 is located at the proximal end of the first arc segment 1832 or the second outer plate end of the movable partition 181 is located at the proximal end of the second arc segment 1842, such as Figure 3f As shown, all or most of the cavity space of the first sub-air inlet chamber 115 corresponds to the upstream of the wind path of the first volute air outlet, and all or most of the cavity space of the second sub-air inlet chamber 116 corresponds to the upstream of the wind path of the second volute air outlet, so that all or most of the fresh air flow of the first sub-air inlet chamber 115 will be diverted to the first volute air outlet, and all or most of the polluted air flow of the second sub-air inlet chamber 116 will be diverted to the second volute air outlet.

[0103] Optionally, the proximal end of the first arc segment 1832 corresponds to the first volute tongue segment, and / or the proximal end of the second arc segment 1842 corresponds to the second volute tongue segment.

[0104] Therefore, compared with the use state when the movable partition 181 is in the first position, the amount of outdoor fresh air output to the indoor side is significantly increased when the movable partition 181 is in the second position, and its diversion air supply effect is close to the fixed partition plate form in the previous embodiment.

[0105] In this way, those skilled in the art can move the movable partition 181 between the first position and the second position according to actual needs and select the actual separation air supply position to dynamically adjust the air volume output ratio of outdoor fresh air and indoor polluted air. Among them, when the movable partition 181 moves from the first position to the second position, the proportion of fresh air output through the first volute air outlet gradually increases, and the proportion of polluted air output through the second volute air outlet gradually increases. When the movable partition 181 moves from the second position to the first position, the proportion of fresh air output through the first volute air outlet gradually decreases, and the proportion of polluted air output through the second volute air outlet gradually decreases.

[0106] In some further optional embodiments not shown in the drawings, the partition component includes a movable partition and a partition driver, and the partition driver can drive the movable partition to move laterally in the air inlet chamber.

[0107] Here, the movable partition plate is arranged in the air inlet cavity in a transversely slidable manner, and its transverse moving plane 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 partition to move in a first direction or a second direction in the transverse direction. The first direction and the second direction are two opposite directions. Optionally, the first direction is to move toward the side where the third side wall is located, and the second opposite direction is to move toward the side where the fourth side wall is located.

[0109] In this embodiment, similar to the partition plate shown in the previous embodiment, the movable partition plate and at least a portion of the cavity wall of the air inlet cavity are surrounded to form a first sub-air inlet cavity, and is surrounded to form a second sub-air inlet cavity with at least another portion of the cavity wall of the air inlet cavity.

[0110] Alternatively, in order to ensure the airtightness between the two sub-inlet chambers during the horizontal movement of the movable partition, the inlet chamber can be constructed in the form of a square chamber, or the interior of the inlet chamber is in the form of a square chamber, and the vertical length of the movable partition is consistent with the vertical length of the inlet chamber. Thus, during the horizontal sliding movement of the movable partition, its longitudinal ends can always abut against the opposite side walls of the inlet chamber, reducing the air leakage gap that may be caused during the movement.

[0111] In this way, when the movable partition moves horizontally in the air inlet cavity, the cavity space of the first sub-air inlet cavity and the second sub-air inlet cavity surrounded by it can be changed. For example, when the movable partition moves toward the third side wall, the cavity space of the first sub-air inlet cavity and the corresponding first sub-air outlet have a larger diameter, and the cavity space of the second sub-air inlet cavity and the corresponding second sub-air outlet have a smaller diameter. Alternatively, when the movable partition moves toward the fourth side wall, the cavity space of the first sub-air inlet cavity and the corresponding first sub-air outlet have a smaller diameter, and the cavity space of the second sub-air inlet cavity and the corresponding second sub-air outlet have a larger diameter.

[0112] In combination with the above embodiment, an outdoor air outlet and an indoor return air outlet are spaced apart on the second side wall, wherein the outdoor air outlet is used to deliver outdoor fresh air to the first sub-air inlet chamber, and the indoor return air outlet is used to deliver indoor dirty air to the second sub-air inlet chamber. Optionally, the lateral movement range of the movable partition is limited to that one longitudinal end portion thereof corresponding to the second side wall is always located between the outdoor air outlet and the indoor return air outlet, so that the outdoor air outlet always corresponds to the first sub-air inlet chamber, and the indoor return air outlet always corresponds to the second sub-air inlet chamber.

[0113] In the above-mentioned multiple embodiments, the fresh air duct 20 is connected to the first air inlet to introduce outdoor fresh air into the first air inlet cavity 11; and the second air duct channel is connected to the second air outlet to discharge indoor polluted air to the outdoors.

[0114] Optionally, the partition form for separating the air inlet channel 1223 of the impeller 122 shown in the previous embodiment can also be applied to the partition component in this embodiment, so that the partition component can not only dynamically adjust the cavity space of the sub-air inlet chamber 11 in the air inlet chamber 11 during the activity, but also dynamically adjust the channel space change of the air inlet channel 1223 in the fan chamber 12 accordingly, so as to enhance the effect of diverting and supplying air from different sources.

[0115] In combination with the above-mentioned embodiment, the first partition plate 191 of the partition member is disposed in the air inlet channel 1223 of the impeller 122, and the second partition plate 192 of the partition member 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 with the movable partition plate 181. Figure 3g Here, the first partition plate 191 is a solution of a movable partition plate 181 that is applied to move relative to the air inlet chamber 11 in a rotational manner.

[0116] Optionally, the partition driver 182 can be driven and connected to the first partition plate 191 or the second partition plate 192, and is used to drive the first partition plate 191 to rotate relative to the fan chamber, and the second partition plate 192 to rotate relative to the air inlet chamber 11, so as to change the partition position of the first partition plate 191 relative to the air inlet channel 1223, and the partition position of the second partition plate 192 (movable partition 181) relative to the air inlet chamber 11.

[0117] In some optional embodiments, at least part of the body of the impeller driver 126 is located in the air inlet channel 1223 of the impeller 122, and accordingly, the first partition plate 191 is formed with an avoidance groove 1911 for avoiding the impeller driver 126, thereby preventing the first partition plate 191 from interfering with the impeller driver 126 during rotation. Figure 3h shown.

[0118] Here, the avoidance groove 1911 is spaced apart from the impeller driver 126, and under the premise of avoiding contact, the gap between the groove edge and the impeller driver 126 is minimized to enhance the airtight effect and reduce the mixing of airflows in the two air inlet areas within the air inlet channel 1223 through the gap.

[0119] In combination with the forms of the fresh air module 1 shown in the above embodiments, several air exchange modes of the fresh air module 1 of the present application are described below. (Outdoor fresh air is indicated by a solid arrow, and indoor polluted air is indicated by a dotted arrow)

[0120] Combination Figures 4a to 4cOptionally, the working mode of the fresh air module 1 includes a fresh air mode. The fresh air mode means that the fresh air module 1 is used to transport outdoor fresh air from the outdoor side to the indoor side. In this mode, the fresh air module 1 does not transport indoor polluted air to the outdoor side. The fresh air mode can supplement outdoor fresh air with better air quality to the indoor side, thereby improving the air quality of the indoor side.

[0121] In some embodiments, in the fresh air mode, 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 fresh air mode, the impeller 122 keeps rotating in a set rotation direction (such as the first rotation direction); the wind shield of the integrated switch part is controlled to move to the first sliding position so that the indoor return air outlet 113 is blocked, and the first air duct channel 231 and the second air duct channel 232 of the fresh air duct 20 are both connected to the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116 of the air inlet cavity 11; the wind blocking block of the air outlet switching mechanism is controlled to be in the first rotation position, so that the second air duct channel 232 is blocked from the switching air cavity, and the fan cavity 12 is connected to the first indoor air outlet 51 and the second indoor air outlet 52.

[0122] In this way, when the impeller 122 rotates, negative pressure suction is generated on the side of the air inlet chamber 11, attracting outdoor fresh air on the outdoor side to flow toward the indoor side through the first air duct channel 231 and the second air duct channel 232, and enter the air inlet chamber 11 through the outdoor air outlet 114 of the module housing 10. Figure 4a and 4c Afterwards, 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 in FIG. Figure 4b The arrows show the direction of air flow.

[0123] Combination Figures 5a to 5c Alternatively, the working mode of the fresh air module 1 includes a two-way air exchange mode. The two-way air exchange mode means that the fresh air module 1 is used to simultaneously transport outdoor fresh air from the outdoor side to the indoor side, and to transport indoor polluted air from the indoor side to the outdoor side. The two-way air exchange mode can simultaneously replenish outdoor fresh air to the indoor side and exhaust indoor polluted air from the indoor side, thereby achieving synchronous replacement of fresh air and polluted air, which can improve indoor air quality more quickly.

[0124] In some embodiments, in the two-way 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 two-way air exchange mode, the impeller 122 keeps rotating in a set rotation direction (such as a first rotation direction); the wind shield of the integrated switch unit is controlled to move to the second sliding position, so that the indoor return air port 113 is open, and the second fresh air outlet port 2321 of the second air duct channel 232 is blocked; the wind blocking block of the air outlet switching mechanism is controlled to be located at the second rotation position, so that the branch port 2322 of the second air duct channel 232 is connected to the switching air cavity, and the switching air cavity is blocked from the second indoor air outlet 52, so that the fan cavity 12 is connected to the first indoor air outlet 51 and the second air duct channel 232.

[0125] In this way, when the impeller 122 rotates, negative pressure suction is generated on the side of the air inlet chamber 11, attracting outdoor fresh air on the outdoor side and indoor polluted 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 sequentially transported to the first indoor air outlet 51 through the first air duct channel 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. Figure 5a and 5c The indoor exhaust air flow path includes indoor polluted air being transported to the second air duct channel 232 through the indoor return air port 113, the second sub-air inlet chamber 116, and the fan chamber 12 in sequence, and the indoor polluted air is finally discharged to the outdoor side through the second air duct channel 232. Figure 5b and 5c The arrows show the direction of air flow.

[0126] Combination Figures 6a to 6d Alternatively, the working mode of the fresh air module 1 includes a full return air mode. The full return air mode means that the fresh air module 1 is used to transport at least part of the outdoor polluted air from the indoor side to the outdoor side, and / or, at least part of the indoor polluted air is filtered and purified and then sent 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 situations where the outdoor ambient air quality is also poor, such as haze weather.

[0127] In some embodiments, in the full return air mode, the indoor polluted air is transported to the outdoor side via the indoor return air port 113, the air inlet chamber 11, the fan chamber 12 and the second air duct channel 232 (exhaust air duct), and / or the indoor polluted air is transported back to the indoor side via the indoor return air port 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 keeps rotating in a set rotation direction (such as the first rotation direction); the wind shield of the integrated switch part is controlled to move to the third sliding position so that the outdoor air port 114 is blocked and the indoor return air port 113 is open; the wind blocking block of the air outlet switching mechanism is controlled to be located at the first rotation position or the second rotation position.

[0128] In this way, when the impeller 122 rotates, negative pressure suction is generated on the side of the air inlet chamber 11, which attracts the indoor polluted air on the indoor side to enter the air inlet chamber 11 through the indoor return air port 113 of the module housing 10, and is divided into the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116. Figure 6a The airflow direction is shown by the arrow in the figure; wherein the indoor polluted air of the first sub-air inlet chamber 115 is filtered and purified by the air filter element 14 and then flows into the fan chamber 12, and then is sent back to the indoor environment from the first indoor air outlet 51, such as Figure 6b and 6c shown.

[0129] The indoor polluted air in the second sub-air inlet chamber 116 is filtered and purified by the air filter element 14 and then flows into the fan chamber 12, and then is transported to the switching air chamber. Here, when the air blocking block is in the first rotation position, the part of the indoor polluted air is sent back to the indoor environment from the second indoor air outlet 52. Figure 6b When the wind block is at the second rotation position, the part of the indoor dirty air is discharged from the second air duct channel 232 to the outdoor environment, such as Figure 6c and 6d shown.

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

[0131] Combination Figure 7 As shown, the method for controlling the fresh air module includes:

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

[0133] S702, when the target parameters meet the condensation formation conditions, the processor controls the partition component to rotate to reduce the fresh air volume.

[0134] The method for controlling the fresh air module provided by the embodiment of the present disclosure is adopted, and the partition component is movably arranged in the air inlet cavity. During the operation of the fresh air module, the target parameter is detected to determine whether the condensation formation conditions are met. If so, 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 volume, thereby reducing the proportion of outdoor fresh air in the mixed air of the fresh air module, and increasing the temperature of the mixed air, thereby achieving an anti-condensation effect, thereby reducing the risk of water blowing.

[0135] 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 the first temperature threshold. If the internal temperature of the fresh air module is less than or equal to the first temperature threshold, it means that the temperature is too low and the possibility of condensation is high, so the condensation degree of the condensation is determined to be about to be or has been formed. In actual application, more thresholds such as the second temperature threshold 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 disposed inside the fresh air module. Figure 1 ). In this way, the real-time temperature can be accurately detected, and the accuracy of temperature detection can be guaranteed.

[0137] Optionally, the first temperature threshold is determined by: 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 inside the fresh air module. Exemplarily, the humidity sensor is arranged inside the first air outlet duct 13. In this way, the real-time humidity can be detected more accurately, and the accuracy of humidity detection can be guaranteed.

[0138] Optionally, 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. In this way, whether the temperature reaches the dew point temperature can reflect whether condensation is easy to form, so determining the first temperature threshold according to the dew point temperature is used to judge the condensation degree of condensation, which is conducive to improving the accuracy of the condensation degree judgment.

[0139] Determining the first temperature threshold according to the dew point temperature includes: determining the first temperature threshold as the dew point temperature.

[0140] In other embodiments, determining the first temperature threshold according to the dew point temperature includes: the processor determines the first temperature threshold as the sum of the dew point temperature and the temperature correction value. The temperature correction value is a positive number. In this way, it can be determined earlier whether the current situation is prone to condensation, thereby more effectively ensuring that condensation does not occur.

[0141] In other embodiments, determining the first temperature threshold according to the dew point temperature includes: the processor determines the first temperature threshold as the difference between the dew point temperature and the temperature correction value. The temperature correction value is a negative number. In this way, it is possible to avoid adjusting the partition component when condensation has not yet formed, resulting in unnecessary sacrifice of fresh air volume.

[0142] Optionally, the first temperature threshold is determined by: determining the correspondence between the internal temperature of the fresh air module and the degree of condensation through historical data, and determining the first temperature threshold according to the correspondence. For example, the internal temperature of the fresh air module is determined each time when condensation begins to occur, and the average, median or mode of the multiple internal temperatures obtained is used as the first temperature threshold. In this way, a more accurate first temperature threshold can be determined based on historical data, which is conducive to improving the accuracy of condensation judgment and subsequent partition component control.

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

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

[0145] Optionally, the processor controls the partition component to rotate, including: the processor controls the partition driver to operate, and controls the partition to rotate a unit angle per unit time until condensation is not easily formed on the surface of the fresh air module.

[0146] Optionally, the processor controls the partition component to rotate, including: the processor controls the partition driver to operate to rotate the movable partition to a target angle.

[0147] The target angle may be directly set by the user.

[0148] In other embodiments, optionally, the method for determining the target angle includes: a processor determining the target angle according to a target parameter.

[0149] Optionally, when the target parameter is the internal temperature of 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 applications, 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 corresponding to the mapping relationship.

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

[0151] Optionally, when 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 rotation speed, which is helpful to slow down the condensation formation process.

[0152] Optionally, after the processor controls the partition component to rotate, the method for controlling the fresh air module includes: obtaining the target parameter again after the first preset time. If the condensation formation condition is still met, the processor controls the impeller to reduce the speed. In this way, it is possible to avoid unnecessary reduction in the impeller speed to affect the fresh air exchange process.

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

[0154] Optionally, when the target parameter meets the condensation formation condition, the method for controlling the fresh air module further includes: the processor controls the electric heating module to start heating. In this way, the fresh air entering the fresh air module is heated to avoid condensation caused by overcooled fresh air.

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

[0156] Combination Figure 8 As shown, the embodiment of the present disclosure provides another method for controlling a fresh air module, comprising:

[0157] S801: The processor obtains target parameters during the operation of the fresh air module.

[0158] S802: When the target parameters meet the condensation formation conditions, the processor determines an initial target angle according to the target parameters.

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

[0160] If yes, go to step S804; if no, go to step S805.

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

[0162] S805, the processor determines that the target angle is the maximum angle allowed for rotation, controls the partition driver to operate to rotate the movable partition to the target angle, and controls the impeller to reduce the rotation speed.

[0163] In actual application, there may be different situations, but due to structural limitations, the angle allowed for the movable partition to rotate is limited. Therefore, after calculating the initial target angle, the maximum angle allowed for the movable partition to rotate is used for judgment. If the allowed rotation angle is less than the initial target angle, it means that the condensation prevention cannot be achieved by simply rotating the partition. At this time, the impeller is controlled to reduce the speed to further prevent condensation.

[0164] The processor controlling the impeller to reduce the rotation speed includes: the processor calculating the difference between the initial target angle and the maximum angle allowed for rotation, and controlling the impeller to reduce the rotation speed according to the difference.

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

[0166] Combination Fig. 9 As shown, the embodiment of the present disclosure provides another method for controlling a fresh air module, comprising:

[0167] S901: The processor obtains the target fresh air volume required indoors.

[0168] S902: The processor determines a target rotation angle according to a target fresh air volume.

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

[0170] S904: The processor obtains target parameters during the operation of the fresh air module.

[0171] S905, when the target parameters meet the condensation formation conditions, the processor controls the partition component to rotate to reduce the fresh air volume.

[0172] In this way, the target rotation angle is first determined according to the target fresh air volume required indoors, and then the condensation formation is determined according to the target parameters during operation to adjust the partition components. When the target parameters have met the condensation formation conditions, it means that condensation is about to occur or has occurred. At this time, a certain amount of fresh air volume is sacrificed and anti-condensation is given priority. The indoor fresh air volume demand is met to the greatest extent while avoiding the occurrence of water blowing.

[0173] Optionally, the processor obtains the target fresh air volume required indoors, including: the processor obtains the volume of the fresh air module's action space, the indoor carbon dioxide concentration, and the outdoor carbon dioxide concentration, and determines the target fresh air volume required indoors based on 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 indoors based on 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 in indoor carbon dioxide concentration under the conditions of the current volume of the space, the indoor carbon dioxide concentration, and the outdoor carbon dioxide concentration; and determines that the fresh air volume corresponding to the change in the indoor carbon dioxide concentration when the indoor carbon dioxide concentration changes to the target carbon dioxide concentration is the target fresh air volume.

[0175] Optionally, the processor determines the target fresh air volume required indoors based on 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 in indoor carbon dioxide concentration under the conditions of the current volume of the space, the indoor carbon dioxide concentration, and the outdoor carbon dioxide concentration; and determines that the fresh air volume corresponding to the change in the indoor carbon dioxide concentration when the indoor carbon dioxide concentration changes to the target carbon dioxide concentration is the target fresh air volume.

[0176] Optionally, the processor determining the target rotation angle according to the target fresh air volume includes: the processor determining the target rotation angle according to a correspondence 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 correspondence 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 situation where the partition component is in different positions is simulated. 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 corresponding relationship between the fresh air volume and the rotation angle.

[0179] According to the corresponding relationship, the rotation angle corresponding to the target fresh air volume can be determined. If the partition component is in the initial position, the rotation angle is the target rotation angle. If the partition component is not in the initial position, the target rotation angle is adjusted according to the rotation angle and the angle between the current partition component and the initial position.

[0180] Combination Figure 3e and Figure 3f As shown, the first position is the initial position. As the movable partition plate moves from the first position to the second position, the amount of fresh air from the outdoor to the indoor increases continuously, which can reduce the indoor carbon dioxide concentration more quickly. That is, the larger the rotation angle, the greater the amount of fresh air.

[0181] When the target parameters meet the condensation formation conditions, the processor controls the partition component to rotate to reduce the fresh air volume, that is, controls the movable partition to move from the second position to the first position.

[0182] Optionally, after the processor controls the partition component according to the target rotation angle, the process further includes: 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 a first concentration threshold.
