Description

TECHNICAL FIELD

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

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

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

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

[0005] In the related product design, there is also a fresh air module scheme with outdoor fresh air and indoor exhaust air dual functions. The fresh air module is internally divided into an air inlet cavity and a fan cavity. The air inlet cavity is divided into two sub-cavities by a partition plate, and the two sub-cavities can be used to respectively deliver outdoor fresh air and indoor polluted air to the fan cavity. A impeller and two air outlet paths are arranged in the fan cavity. The impeller can drive the airflow to flow and make the outdoor fresh air and the indoor polluted air flow to different air outlet paths. However, it is found that in actual use, a lot of outdoor fresh air and indoor polluted air are mixed in the fan cavity, which affects the shunt air supply effect of the fresh air module.

[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.

[0114] 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, humidifiers and the like, 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, etc. controllably, so as to improve indoor air quality, improve environmental comfort, etc.

[0115] As Figure 1 And 1aAs shown, the fresh air module 1 mainly includes 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, a fan 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 includes 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 including outdoor fresh air or indoor dirty air, the air outlet flow direction including flowing 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.

[0116] In some optional embodiments, in combination with Figure 2 、 2a and 2b, 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 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.

[0117] Optionally, the air inlet cavity 11 is upstream of the fan cavity 12 in the air flow path, i.e. 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, i.e. 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.

[0118] In some embodiments, in combination with Figures 3a to 3eAs 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, the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116 form a relatively independent air path respectively, 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 conveyed along the respective air path to the fan cavity 12. 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.

[0119] 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 used to convey outdoor fresh air from the outdoor side at the same time, or are used to convey indoor dirty air from the indoor side at the same time. 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 to convey outdoor fresh air from the outdoor side, and the other is used to convey indoor dirty air from the indoor side. Here, the separation component can at least be used to separate the air path when the two sub-air inlet cavities 11 convey air from different air sources, and to block or slow down the mixing of air with different cleanliness states.

[0120] Optionally, the overall outer contour of the air inlet cavity 11 is a flat cavity structure, which comprises an outer cavity wall 1115, an air outlet cavity wall 1116, a first side wall 1111, a second side wall 1112, a third side wall 1113 and a fourth side wall 1114, as shown in Figure 3a and 3b . Among them, the wall surfaces of the outer cavity wall 1115 and the air outlet cavity wall 1116 are parallel and spaced apart, the first side wall 1111, the second side wall 1112, the third side wall 1113 and the fourth side wall 1114 are respectively arranged on the outer circumferential side of the spacing space between the outer cavity wall 1115 and the air outlet cavity wall 1116, and the outer cavity wall 1115, the air outlet cavity wall 1116, the first side wall 1111, the second side wall 1112, the third side wall 1113 and the fourth side wall 1114 together form the aforementioned air inlet cavity 11. Here, the transverse two sides (long sides) of each side wall of the first side wall 1111, the second side wall 1112, the third side wall 1113 and the fourth side wall 1114 are respectively connected with the corresponding side of the outer cavity wall 1115 and the air outlet cavity wall 1116, and the longitudinal two sides (short sides) are respectively connected with the short sides of the adjacent other side walls.

[0121] In the embodiment, the first side wall 1111 and the second side wall 1112 are arranged oppositely, and the third side wall 1113 and the fourth side wall 1114 are arranged oppositely. For example, in combination with Figure 2b and 3bAs shown, the first side wall 1111 is arranged at the top position of the air inlet cavity 11 and is configured as the top surface of the air inlet cavity 11; the second side wall 1112 is arranged at the bottom position of the air inlet cavity 11 and is configured as the bottom surface of the air inlet cavity 11; the third side wall 1113 is arranged at the front position of the air inlet cavity 11 and is configured as the front surface of the air inlet cavity 11; and the fourth side wall 1114 is arranged at the rear position of the air inlet cavity 11 and is configured as the back surface of the air inlet cavity 11. In this example, the outer cavity wall 1115 is the left surface of the air inlet cavity 11, and the air outlet cavity wall 1116 is the right surface of the air inlet cavity 11.

[0122] Optionally, one or more of the first side wall 1111, the second side wall 1112, the third side wall 1113, and the fourth side wall 1114 is a straight plate surface, for example Figure 3a and 3b The third side wall 1113 and the fourth side wall 1114 shown in FIG. 11C are both in the form of straight plate surfaces. Yet another option is that one or more of the first side wall 1111, the second side wall 1112, the third side wall 1113, and the fourth side wall 1114 is a non-straight plate surface, for example Figure 2b and 3b The plate surfaces of the first side wall 1111 and the second side wall 1112 shown in FIG. 11B are in the form of plate surfaces composed of multiple straight surface portions and / or arc surface portions.

[0123] In this embodiment, the partial side walls are designed in the form of non-straight plate surfaces, which can achieve the effect of closer cooperation between the air inlet cavity 11 and other components of the fresh air module 1, so as to reduce the number of air leakage gaps and reduce the air path resistance. For example, the arc surface portion of the first side wall 1111 is adapted to the volute curve of the fan cavity 12, so that it is more closely connected with the corresponding position of the fan cavity 12 and has better air tightness.

[0124] In some optional embodiments, the first side wall 1111, the second side wall 1112, the third side wall 1113, the fourth side wall 1114, and the outer cavity wall 1115 are in an integrated structure, thereby reducing the existence of air leakage gaps and improving the sealing performance of the air inlet cavity 11.

[0125] In an embodiment, in combination with Figure 3c As shown, the air inlet cavity air outlet 112 is formed in the air outlet cavity wall 1116, and the air inlet cavity 11 is in communication with the fan cavity 12 through the air inlet cavity air outlet 112. In this embodiment, the air inlet cavity air outlet 112 should at least cover the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116, so that the air flowing through the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116 can flow to the fan cavity 12 through the air inlet cavity air outlet 112.

[0126] Optionally, the air inlet cavity air outlet 112 is configured in a regular shape such as a circle, an ellipse, a square, a trapezoid, or other irregular shapes. Here, the specific shape and size of the air outlet of the air inlet cavity 112 can be set according to actual needs, and the present application does not limit this.

[0127] Further optionally, the air inlet cavity air outlet 112 is provided with an air outlet grille, which can not only intercept large-volume sundries such as stones, paper balls, lint, etc., but also has a protective effect, so that the user's fingers will not be mistakenly inserted into the fan cavity 12 when replacing the air filter element 14, preventing being cut by the impeller 122 blade 1222.

[0128] Illustratively, the air outlet grille includes one or more circumferential grille bars and one or more radial grille bars. Among them, the plurality of circumferential grille bars are coaxially arranged and gradually increase in radius, and the plurality of circumferential grille bars are arranged on the same plane along the radial direction from inside to outside, and the plane is the plane where the air inlet cavity air outlet 112 is located. In addition, one end of each radial grille bar is connected to the central axis of the air inlet cavity air outlet 112, and the other end extends radially outward, and the plurality of radial grille bars are arranged at the air inlet cavity air outlet 112 in a radial pattern and intersect with the circumferential grille bars. In this way, the circumferential grille bars and the radial grille bars are staggered and arranged to achieve the function of interception and filtration.

[0129] In some optional embodiments, in combination with Figure 3a and 3b As shown, the partition component includes a partition plate 15 arranged inside the air inlet cavity 11 and extending from one side wall to the opposite side wall of the air inlet cavity 11. Optionally, the plate body of the partition plate 15 extends longitudinally from the first side wall 1111 to the second side wall 1112, that is, the longitudinal top end of the partition plate 15 is connected to the first side wall 1111, and the longitudinal bottom end is connected to the second side wall 1112; At the same time, the plate body of the partition plate 15 extends transversely from the outer cavity wall 1115 to the air outlet cavity wall 1116. Thus, the air inlet cavity 11 is divided into two air inlet sub-zones arranged in space front and back, that is, the first air inlet sub-cavity 115 and the second air inlet sub-cavity 116 mentioned above.

[0130] Illustratively, in combination with Figure 3c and 3dAs shown, the first sub-inlet air cavity 115 is located in the front space area of the inlet air cavity 11, which is formed by the third side wall 1113, the front side of the partition plate 15, and the part of the outer cavity wall 1115, the outlet air cavity wall 1116, the first side wall 1111 and the second side wall 1112 near the front side. The second sub-inlet air cavity 116 is located in the rear space area of the inlet air cavity 11, which is formed by the fourth side wall 1114, the back side of the partition plate 15, and the part of the outer cavity wall 1115, the outlet air cavity wall 1116, the first side wall 1111 and the second side wall 1112 near the rear side.

[0131] In an embodiment, the plate body extends transversely to the outlet air cavity wall 1116, which separates the outlet air port 112 of the inlet air cavity into a first sub-outlet air port and a second sub-outlet air port. The first sub-inlet air cavity 115 is in communication with the first sub-outlet air port, and the second sub-inlet air cavity 116 is in communication with the second sub-outlet air port.

[0132] Optionally, from the perspective of the longitudinal section of the partition plate 15, the plate body line shape of the partition plate 15 is configured as a straight line shape, a curved line shape, a broken line shape, or the like, or is formed by one or more straight line shapes and / or one or more curved line shapes. Here, the plate body line shape of the partition plate 15 can be adjusted according to factors such as the cavity volume distribution and air resistance in the inlet air cavity 11. For example, in the case where the cavity volume of the first sub-inlet air cavity 115 needs to be greater than that of the second sub-inlet air cavity 116, the partition plate 15 can be configured as a curved or broken line shape with the plate surface protruding towards the second sub-inlet air cavity 116, so as to increase the actual space allocated to the first sub-inlet air cavity 115. Alternatively, in the case where the cavity volumes of the first sub-inlet air cavity 115 and the second sub-inlet air cavity 116 need to be approximately equal, the partition plate 15 can be configured as a straight line shape and arranged at the center line position of the inlet air cavity 11, so as to achieve equal distribution of space to the two sub-inlet air cavities 11.

[0133] In an embodiment, the cavity volume of the first sub-inlet air cavity 115 is greater than or equal to that of the second sub-inlet air cavity 116, so that in the bidirectional air exchange mode, the outdoor fresh air volume delivered to the indoor side via the first sub-inlet air cavity 115 is greater than the outdoor polluted air volume delivered to the outdoor side via the second sub-inlet air cavity 116, thereby achieving a positive pressure air supply effect.

[0134] In yet some optional embodiments, the fresh air module 1 further comprises an air filter 14, which can be used to filter and purify the air flowing through the fresh air module 1, so as to reduce the content of dust, PM2.5 and other air pollutants in the air.

[0135] Optionally, the air filter 14 is arranged in one of the inlet air cavity 11 and the fan cavity 12. For example, in combination with the above-mentioned embodiment, the air filter 14 is arranged in the second sub-inlet air cavity 116. Figure 4 、 4aAs shown in Figs. 4a and 4b, the air filter 14 is arranged in the air inlet cavity 11, which can adsorb and intercept air pollutants when the air flows through the air inlet cavity 11. In this way, the air quality can be effectively improved, and the problem of fan impeller 122 abrasion caused by large particles such as sand entering the fan cavity 12 can be reduced. In the embodiment, the air filter 14 is arranged close to the air outlet cavity wall 1116 of the air inlet cavity 11, so as to better fit and cover the air outlet 112 of the air inlet cavity, so that most of the air flowing to the air outlet 112 of the air inlet cavity can pass through the air filter 14 for purification and filtration.

[0136] The air filter 14 itself has a limitation of adsorption saturation. After the fresh air module 1 is used for a long time, the air filter 14 gradually reaches the upper limit of its adsorption capacity, and at this time, the air filter 14 needs to be cleaned and replaced in time. In this embodiment, the air filter 14 is detachably arranged in the fresh air module 1, so that the user can operate the air filter 14 by himself / herself when needed. Alternatively, the air filter 14 can be pulled out of the air inlet cavity 11, and the user can pull out the air filter 14 in a dirty state from the fresh air cavity, or push the air filter 14 in a brand-new state into the fresh air cavity.

[0137] Alternatively, the air filter 14 can be moved into / out of the air inlet cavity 11 through the socket 117 provided on the outer side wall of the air inlet cavity 11. In combination with the foregoing embodiments, the outer side wall in which the socket 117 can be provided is one of the outer cavity wall 1115, the first side wall 1111, the second side wall 1112, the third side wall 1113 and the fourth side wall 1114 of the air inlet cavity 11. In combination with the foregoing embodiments, the socket 117 can be provided on the outer side wall of the air inlet cavity 11, and the air filter 14 can be moved into / out of the air inlet cavity 11 through the socket 117. Figure 4b As shown in Fig. 4c, the socket 117 is provided on the third side wall 1113 of the air inlet cavity 11, and the third side wall 1113 is the side wall of the air inlet cavity 11 close to the front side and facing the user, so that the socket 117 is located to make the user more convenient to pull out the air filter 14. In this embodiment, the shape and size of the socket 117 are adapted to the cross-sectional shape and size of the air filter 14.

[0138] In the foregoing embodiments, the plate body of the partition plate 15 extends transversely from the outer cavity wall 1115 to the air outlet cavity wall 1116, so that the air filter 14 inserted into the air inlet cavity 11 also covers the path in the transverse direction of the plate body. In order to avoid the structural interference between the partition plate 15 and the air filter 14, the socket 118 for pulling out the air filter 14 is further provided on the partition plate 15 in this embodiment, so that the partition plate 15 avoids the air filter 14 by using the socket 118, and the two are arranged in the air inlet cavity 11 without affecting each other, as shown in Fig. 4d. Figure 4c

[0139] ​Optionally, the vertical height of the slot 118 is greater than or equal to the vertical length of the air filter element 14, and / or the axial width of the slot 118 is greater than or equal to the lateral length of the air filter element 14. In this way, the slot 118 can be guaranteed not to block the air from moving in and out.

[0140] In some optional embodiments, the slot 118 is a side surface of the corresponding air outlet cavity wall 1116 of the partition plate 15, which is recessed in the axial direction of the air inlet cavity 11, as shown in Figure 4c The slot 118 is approximately U-shaped. In embodiments, the slot type of the slot 118 is adapted to the cross-sectional shape of the air filter element 14 to reduce the air leakage gap formed between the edge of the slot 118 and the air filter element 14. For example, the cross-sectional shape of the air filter element 14 is rectangular, and the slot type of the slot 118 is also configured in the form of a rectangular groove.

[0141] Optionally, the slot depth of the slot 118 is less than or equal to 1 / 2 of the axial length of the partition plate 15. For example, the slot depth of the slot 118 is set to 1 / 3, 1 / 4, etc. of the axial length of the partition plate 15. Here, the slot size can be made not too large to affect the structural strength of the partition plate 15, and at the same time, since the air inside the air filter element 14 is free to flow and has no spatial separation effect, limiting the slot depth of the slot 118 can also reduce the adverse effect of the air filter element 14 on the spatial separation effect of the air inlet cavity 11. For example, the slot depth of the slot 118 is l, and the axial length of the partition plate 15 is L, which needs to meet the size design requirement of l≤L / 2.

[0142] In some embodiments, the air outlet cavity wall 1116 of the air inlet cavity 11 is provided with a partition rib 16, which is protruded from the wall surface of the air outlet cavity wall 1116 towards the outer cavity wall 1115, and can be cooperated with the partition plate 15 to jointly form the slot 118, as shown in Figure 4d .

[0143] In combination with Figure 4c and 4d , the slot 118 opened in the partition plate 15 corresponds to the lateral side and the longitudinal two sides of the air filter element 14, and the partition rib 16 corresponds to the other lateral side of the air filter element 14. In this way, the partition rib 16 can substantially enhance the close-fitting of the air filter element 14 and the side of the air outlet cavity wall 1116, reduce the air leakage gap, and further improve the spatial separation effect of the air inlet cavity 11.

[0144] In an embodiment, the partition rib 16 is in line with the linear shape of the partition plate 15, and the positions coincide in the axial direction. In this way, this part of the air flow path of the "partition plate 15-partition rib 16" does not form an additional protrusion, and the flow path is smooth and smooth, avoiding the influence of wind resistance on the air. For example, the linear shape of the extension of the partition plate 15 adopts a straight line shape, and the partition rib 16 is also adaptively configured as a straight line convex rib form; or, the linear shape of the extension of the partition plate 15 adopts an arc line shape, and the partition rib 16 is adaptively configured as an arc line convex rib form.

[0145] In still some optional embodiments, the insertion slot 118 is a channel structure hollowed and formed along the thickness direction of the partition plate 15. Here, the insertion slot 118 is opened in the middle part of the partition plate 15 or the part close to the air outlet cavity wall 1116, and is formed through along the thickness direction of the partition plate 15.

[0146] In the present embodiment, the insertion slot 118 includes a first slot edge, a second slot edge, a third slot edge, and a fourth slot edge. The first slot edge is located at a position close to the first side wall 1111, the second slot edge is located at a position close to the second side wall 1112, the third slot edge is located at a position close to the outer cavity wall 1115, and the fourth slot edge is located at a position close to the air outlet cavity wall 1116. The four slot edges collectively enclose the insertion slot 118 for inserting the air filter element 14. Compared with the form of the insertion slot 118 collectively enclosed by the partition plate 15 and the partition rib 16 in the previous embodiment, the present embodiment does not need to provide the partition rib 16 on the air outlet cavity wall 1116, simplifying the structure of the air inlet cavity 11.

[0147] In some embodiments, an elastic sealing member is provided on the inner side periphery of the insertion slot 118, which can be used to block the assembly gap between the insertion slot 118 and the air filter element 14, so as to reduce the air leakage amount of the assembly gap. Optionally, the elastic sealing member is provided on at least one inner periphery of the insertion slot 118. For example, for the insertion slot 118 in the form of a U-shaped slot, the elastic sealing member can be provided on any one of the slot edges of the U-shaped slot, and / or on the edge of the partition rib 16 corresponding to the air filter element 14. Figure 4c For the insertion slot 118 in the form of a U-shaped slot, the elastic sealing member can be provided on any one of the slot edges of the U-shaped slot, and / or on the edge of the partition rib 16 corresponding to the air filter element 14.

[0148] Optionally, the elastic sealing member can be of a rubber strip, wool strip, or the like type. Moreover, the elastic sealing member can be fixedly connected with the inner side periphery of the insertion slot 118 by means of gluing, clamping, or the like.

[0149] In still some optional embodiments, in order to make the air filter element 14 more smoothly move in / out of the air inlet cavity 11, the present application provides a slide assembly in the air inlet cavity 11 for defining the pulling track of the air filter element 14, which can be used to define the movement path of the air filter element 14 relative to the air inlet cavity 11.

[0150] Optionally, the slide assembly comprises a first rail 171 and a second rail 172, and the spacing of both the first rail 171 and the second rail 172 is configured as the pulling space of the air filter 14. In this regard, Figure 3c and 4d As shown in , the first rail 171 is arranged on the air outlet cavity wall 1116 and is formed in extension along the pulling direction, and the first rail 171 is located on the upper side of the air inlet cavity air outlet 112 and is used for limiting above the air filter 14. The second rail 172 is arranged on the air outlet cavity wall 1116 and is formed in extension parallel to the first rail 171, and the second rail 172 is located on the lower side of the air inlet cavity air outlet 112 and is used for limiting below the air filter 14. The first rail 171 and the second rail 172 are arranged in parallel, and through the cooperation of the first rail 171 and the second rail 172, the air filter 14 can be pulled and moved along the straight line trajectory defined by the two rails.

[0151] Figure 4d As shown in , the first rail 171 is a first guide plate strip protruding from the air outlet cavity wall 1116 towards the outer cavity wall 1115, and the first guide plate strip extends longitudinally from the third side wall 1113 to the fourth side wall 1114, that is, extends from the front side of the air inlet cavity 11 to the back side position. Similarly, the second rail 172 is also a second guide plate strip protruding from the air outlet cavity wall 1116 towards the outer cavity wall 1115, and the second guide plate strip is also formed in extension longitudinally from the third side wall 1113 to the fourth side wall 1114. After the air filter 14 is inserted into the air inlet cavity 11 from the socket 117 of the third side wall 1113, the top surface of the air filter 14 abuts against the lower surface of the first guide plate strip, and the bottom surface abuts against the upper surface of the second guide plate strip, which can reduce the occurrence of dislocation of the air filter 14.

[0152] In the foregoing embodiments, optionally, the type of the air filter 14 includes but is not limited to a primary filter, a high-efficiency filter, an activated carbon filter, and the like. Those skilled in the art can select a suitable filter type according to actual purification needs, and the present application does not limit this.

[0153] In still some optional embodiments, in order to further improve the space separation effect of the air inlet cavity 11, a filter separation strip 141 is arranged inside the air filter 14, and the filter separation strip 141 separates the filter into two filter parts corresponding to two air inlet sub-zones (air inlet cavities 11). Here, the filter separation strip 141 can block the flow of air between the two filter parts, as shown in Figure 4a .

[0154] Here, the overall outer contour of the filter separation strip 141 is in the form of a flat plate strip, which extends laterally along the side of the air filter 14 close to the separation plate 15 to the side close to the separation rib 16, and extends longitudinally along the top surface of the air filter 14 to the bottom surface position.

[0155] In combination Figure 4a As shown, the filter core partition strip 141 divides the air filter core 14 into a first filter core portion 142 and a second filter core portion 143. The first filter core portion 142 is located on the side corresponding to the first sub-air inlet cavity 115 and is used to filter and purify the air flowing through the first sub-air inlet cavity 115. The second filter core portion 143 is located on the side corresponding to the second sub-air inlet cavity 116 and is used to filter and purify the air flowing through the second sub-air inlet cavity 116. Due to the partitioning effect of the filter core partition strip 141, the air flowing through the first filter core portion 142 cannot flow to the second filter core portion 143, and vice versa, thereby avoiding the mixing of the air of the two sub-air inlet cavities 11 in the air filter core 14.

[0156] Optionally, the filter core partition strip 141 is consistent with the linear shape of the partition plate 15 and is located at the same position in the axial direction. In this way, the air flow path formed by the partition plate 15, the filter core partition strip 141, and the partition rib 16 does not form an additional protrusion, the flow path is smooth, and the air flow resistance is effectively reduced. For example, the linear shape of the extension of the partition plate 15 is a straight line, and the filter core partition strip 141 is also configured in the form of a straight line. Alternatively, the linear shape of the extension of the partition plate 15 is an arc, and the filter core partition strip 141 is also configured in the form of an arc. Here, the thicknesses of the partition plate 15, the filter core partition strip 141, and the partition rib 16 are substantially the same to ensure the smoothness of the air flow path plane.

[0157] In some other optional embodiments, the fan cavity 12 comprises a fan volute 121 and an impeller 122. The impeller 122 is rotatably arranged inside the fan volute 121 and is used to rotate to generate driving air flow through the module housing 10. In this embodiment, the impeller 122 can at least drive the air to flow from the air inlet cavity 11 to the fan cavity 12. Figures 5 to 5e In an embodiment, the fan volute 121 is configured in a detachable split structure, as shown in FIG. 12, which comprises a first volute portion 1211 and a second volute portion 1212. The detachable design can facilitate the impeller 122 to be loaded into / removed from the fan volute 121, and facilitate the assembly and maintenance of the fan volute 121. Here, the first volute portion 1211 is located on the side close to the air inlet cavity 11, and the second volute portion 1212 is located on the side of the air inlet cavity 11. The two portions are combined to form the fan volute 121. Optionally, the first volute portion 1211 and the second volute portion 1212 can be fixed by clamping, screwing, riveting, etc., which has the advantages of firm connection and quick disassembly and assembly.

[0158] Figure 5c

[0159] ​​The fan volute 121 has a volute air inlet 123, which is used to communicate with the air outlet 112 of the air inlet chamber 11, so that the air enters the fan volute 121 through the air outlet 112 of the air inlet chamber and the volute air inlet 123 in sequence. In this embodiment, the volute air inlet 123 is formed on the first volute portion 1211, and the shape and size of the volute air inlet 123 are matched with the air outlet 112 of the air inlet chamber. For example, the air outlet of the air inlet chamber 11 is a circular air port, and the volute air inlet 123 is also configured in the form of a circular air port.

[0160] Optionally, the first volute portion 1211 and the air outlet chamber wall 1116 are integrated into one structure, that is, the first volute portion 1211 and the air outlet chamber wall 1116 are respectively two side surfaces of the same housing, the first volute portion 1211 corresponds to one side of the impeller 122, and the air outlet chamber wall 1116 corresponds to one side of the air filter element 14. Moreover, the air outlet 112 of the air inlet chamber wall 1116 and the volute air inlet 123 of the first volute portion 1211 are also integrated into one air port. In this way, the number of components of the module housing 10 can be reduced, and the overall structure is simplified.

[0161] In some embodiments, in combination Figure 6 As shown, the impeller 122 includes a hub 1221 and a plurality of blades 1222. The hub 1221 is configured in the form of a ring structure, and the inner space thereof is used as an air inlet channel 1223 of the impeller 122, which is formed in the axial direction of the impeller 122. The number of hubs 1221 is two, and they are coaxially and spaced apart. The space between the two hubs 1221 is used to accommodate the plurality of blades 1222. Here, each blade 1222 is configured in the form of a strip-shaped sheet structure, and one end thereof is fixed to one of the hubs 1221, and the other end is fixedly connected to the other hub 1221. From the projection direction of the axis of the hub 1221, each blade 1222 is arranged at equal intervals along the outer peripheral line of the hub 1221, and is arranged obliquely relative to the outer peripheral line of the hub 1221, so that the air entering the air inlet channel in the axial direction of the impeller 122 is driven by the blades 1222 to diffuse outward in the radial direction, and then enters the housing space of the fan volute 121.

[0162] In the embodiment, the plurality of blades 1222 are uniformly arranged along the outer peripheral line to jointly form the air inlet channel 1223.

[0163] Optionally, the impeller 122 has a first rotation direction or a second rotation direction, and the first rotation direction is opposite to the second rotation direction. From the axial direction of the air inlet chamber 11 to the fan chamber 12, the first rotation direction is the clockwise direction of the airflow, and the second rotation direction is the counterclockwise direction of the airflow.

[0164] In some optional embodiments, the fresh air module further comprises a impeller driver 126, which is in driving connection with the impeller 122, for driving the impeller 122 to rotate in the fan cavity 12.

[0165] In some optional embodiments, the module housing 10 is provided with a first indoor air outlet 51 and / or a second indoor air outlet 52. The first indoor air outlet 51 and the second indoor air outlet 52 can be used to send air to different directions respectively, so as to achieve multi-angle and wide-range air sending effect.

[0166] Optionally, the first indoor air outlet 51 is used to send air to one of the front side, the back side, the top side, the bottom side, the left side or the right side of the fresh air module 1, and the second indoor air outlet 52 is used to send air to another of the front side, the back side, the top side, the bottom side, the left side or the right side of the fresh air module 1. Figure 5 And 5a In the embodiment shown, the first indoor air outlet 51 is used to send air to the front-up direction, and the second indoor air outlet 52 is used to send air to the down-front direction.

[0167] In some optional embodiments, the module housing 10 further comprises a first air outlet duct 13, which is connected to the module housing 10 and located at the air outlet side of the air inlet cavity 11 (the fan cavity 12), for constructing the 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, which is connected to the module housing 10 and located at the air outlet side of the air inlet cavity 11 (the fan cavity 12), for constructing the 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.

[0168] In the above embodiments, 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, the actual air sending direction can be adjusted. For example, in the above embodiment, the first indoor air outlet 51 is used to send air to the front-up direction, and the corresponding first air outlet duct 13 can be extended and formed towards the front-up direction, and the duct air outlet end thereof is oriented towards the front-up direction.

[0169] 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 communicated with the fan cavity 12 through the fan cavity 12. In the embodiment, the first indoor air outlet 51 and the second indoor air outlet 52 are respectively communicated with the outer peripheral shell wall of the fan volute 121, wherein the first indoor air outlet is communicated with the top position of the outer peripheral shell wall, and the second indoor air outlet 52 is communicated with the bottom position of the outer peripheral shell wall. In the fan cavity 12, the impeller 122 rotates downward, and the air located upstream of the rotation direction of the first indoor air outlet 51 will preferentially and concentratedly flow to the first indoor air outlet 51, as shown by the solid arrow airflow in Figure 7 , and the air located upstream of the rotation direction of the second indoor air outlet 52 will preferentially and concentratedly flow to the second indoor air outlet 52, as shown by the dashed arrow airflow in Figure 7 .

[0170] In some embodiments, as shown in Figure 5b and 5c , the fan volute 121 is provided with a first volute air outlet 124 and a second volute air outlet 125. The first volute air outlet 124 is provided at the top position of the outer peripheral shell wall of the fan volute 121, and is used to communicate the fan volute 121 and the first indoor air outlet 51, so that at least part of the airflow in the fan volute 121 is transported to the first indoor air outlet 51 through the first volute air outlet 124. The second volute air outlet 125 is provided at the bottom position of the outer peripheral shell wall of the fan volute 121, and is used to communicate the fan volute 121 and the second indoor air outlet 52, so that at least part of the airflow in the fan volute 121 is transported to the second indoor air outlet 52 through the second volute air outlet 125.

[0171] In the first rotation direction of the impeller 122 shown in Figure 7 , the first indoor air outlet 51 is arranged corresponding to the first sub-air inlet cavity 115 and located in the middle and lower reaches of the rotation flow direction of the impeller 122, that is, the airflow flowing into the fan volute 121 from the first sub-air inlet cavity 115 is located in the middle and upper reaches of the first indoor air outlet 51, so that the airflow flowing through the first sub-air inlet cavity 115 will flow to the first indoor air outlet 51, and most of the airflow will be sent out through the first indoor air outlet 51. Similarly, the second indoor air outlet 52 is arranged corresponding to the second sub-air inlet cavity 116 and located in the middle and lower reaches of the rotation flow direction of the impeller 122, that is, the airflow flowing into the fan volute 121 from the second sub-air inlet cavity 116 is located in the middle and upper reaches of the second indoor air outlet 52, so that the airflow flowing through the second sub-air inlet cavity 116 will flow to the second indoor air outlet 52, and most of the airflow will be sent out through the second indoor air outlet 52.

[0172] In the embodiment, the first volute air outlet 124 comprises a first outer extension segment 1241 away from the volute axis and a first volute tongue segment 1242 close to the volute axis, the first outer extension segment 1241 and the first volute tongue segment 1242 are oppositely spaced, and the spacing space between the two is used as an air flow channel, as shown in Figure 5d Similarly, the second volute air outlet 125 comprises a second outer extension segment 1251 away from the volute axis and a second volute tongue segment 1252 close to the volute axis, the second outer extension segment 1251 and the second volute tongue segment 1252 are oppositely spaced, and the spacing space between the two is used as an air flow channel, as shown in Figure 5e Optionally, the first sub-air inlet cavity 115 delivers air flow to the fan cavity 12 mainly in the range of the second volute tongue segment 1252 to the first volute tongue segment 1242 in the first rotation direction, as shown in the A range area in Figure 8 Similarly, the second sub-air inlet cavity 116 delivers air flow to the fan cavity 12 mainly in the range of the first volute tongue segment 1242 to the second volute tongue segment 1252 in the first rotation direction, as shown in the B range area in Figure 8 Similarly, the second sub-air inlet cavity 116 delivers air flow to the fan cavity 12 mainly in the range of the first volute tongue segment 1242 to the second volute tongue segment 1252 in the first rotation direction, as shown in the B range area in

[0173] To achieve the division of the two air delivery coverage areas mentioned above, correspondingly, in the axial projection of the partition plate 15 relative to the direction of the fan volute 121, the longitudinal first end (longitudinal top end) of the partition plate 15 extends to the shell wall close to the first volute tongue segment 1242, and the longitudinal second end (longitudinal bottom end) extends to the shell wall close to the second volute tongue segment 1252, as shown in Figure 8 .

[0174] In the embodiment, the plate body of the partition plate 15 extends in a curve, and the curve direction corresponds to the air outlet direction of the first volute air outlet 124 and the second volute air outlet 125, so as to reduce the air resistance during the air flow through the plate surface of the partition plate 15 and reduce the wind pressure loss.

[0175] As shown in Figure 3e , the partition plate 15 comprises a first arc plate segment 151, a second arc plate segment 152, and an intermediate arc plate segment 153. In the axial projection of the partition plate 15 relative to the direction of the fan volute 121, the upper end of the first arc plate segment 151 extends to the shell wall close to the first volute tongue segment 1242, and the lower end extends to the axial direction of the fan volute 121 along the curve of the first volute tongue segment 1242 of the fan volute 121. And, also in the axial projection of the partition plate 15 relative to the direction of the fan volute 121, the lower end of the second arc plate segment 152 extends to the shell wall close to the second volute tongue segment 1252, and the upper end extends to the axial direction of the fan volute 121 along the curve of the second volute tongue segment 1252 of the fan volute 121. The two ends of the intermediate arc plate segment 153 are respectively connected to the extension ends of the first arc plate segment 151 and the second arc plate segment 152 towards the axis, i.e. the lower end of the first arc plate segment 151 and the upper end of the second arc plate segment 152.

[0176] In the present embodiment, in combination with Figure 8 As shown, the extension direction of the first arc plate segment 151 is adapted to the first volute tongue segment 1242, and the extension direction of the second arc plate segment 152 is adapted to the second volute tongue segment 1252, so that the airflow is more smooth in the process of flowing through the air inlet cavity 11, the fan cavity 12 and finally being divided into the first volute air outlet 124 and the second volute air outlet 125, and the resistance influence caused by the cavity wall on the airflow flow is reduced.

[0177] Optionally, the extension curve of the first arc segment can be a curve track with the same curvature as the first volute tongue segment 1242, or a curve track with an acute angle included angle with the curve of the first volute tongue segment 1242. Similarly, the extension curve of the second arc segment can be a curve track with the same curvature as the second volute tongue segment 1252, or a curve track with an acute angle included angle with the curve of the second volute tongue segment 1252. In addition, the curve track of the first arc plate segment 151 and the second arc plate segment 152 respectively has a tendency to bend and extend towards the axis of the fan volute 121, rather than necessarily pointing to the axis.

[0178] Optionally, the first arc plate segment 151, the second arc plate segment 152 and the intermediate arc plate segment 153 adopt an integrated structure, so that there is no air leakage gap between the plate segments of the partition plate 15, and the sealing performance of the air inlet cavity 11 is improved.

[0179] It should be understood that the extension direction of the partition plate 15 and the setting position of the longitudinal two end points in the present embodiment are mainly set according to factors such as the opening position of the two indoor air outlets and the rotation direction of the impeller 122. For example, in the embodiment, the two indoor air outlets are respectively located at the upper and lower sides of the fan cavity 12, so the partition plate 15 also extends vertically as a whole. When the arrangement position of the indoor air outlet is changed, such as front and rear air outlets, the extension direction of the partition plate 15 also needs to be adaptively adjusted. Therefore, based on the technical concept disclosed in the present application, other deformation adjustment schemes of the indoor air outlet opening position and the form of the partition plate 15 according to the actual air supply needs should also be covered within the protection scope of the present application.

[0180] In some other embodiments not shown in the drawings, the partition member comprises a first partition portion and / or a second partition portion.

[0181] The first partition portion is arranged in the air inlet passage 1223, and is used to divide the air inlet passage 1223 into a first air inlet region and a second air inlet region. The airflow in the first air inlet region is inclined to flow to the first volute air outlet 124, and the airflow in the second air inlet region is inclined to flow to the second volute air outlet 125.

[0182] The embodiment is provided with a separation component in the air inlet channel 1223 of the impeller 122 of the fan cavity 12, which can play a role in spatially separating the air inlet channel 1223, separating the air inlet channel 1223 into two air inlet areas, effectively reducing the mixing of air flow between the two air inlet areas, so that the air in each part of the two air inlet areas can be more biased to the corresponding air outlet for air outlet, thereby enhancing the shunt air supply effect of the fresh air module 1.

[0183] Optionally, the first separation part includes a first separation plate, the plate body of which extends longitudinally from the blade 1222 on one side of the axis of the impeller 122 to the blade 1222 on the other side of the axis, and the longitudinal ends of the first separation plate are spaced apart from the inner edges of the corresponding blades 1222. In this way, not only can the air leakage gap between the longitudinal ends of the first separation plate and the inner edges of the blades 1222 be reduced, but the mixing of air flow between the first air inlet area and the second air inlet area can also be reduced, and at the same time, the first separation plate and the impeller 122 can be prevented from interfering with each other, causing the first separation plate to collide with and deform the blades 1222.

[0184] In the embodiment, the air inlet channel 1223 is formed in the axial direction of the impeller 122, so the air entering the air inlet channel 1223 is also swirled and divided into the air outlet side by the blades 1222 in the entire axial direction. Correspondingly, the plate body of the first separation plate is formed in the axial direction of the impeller 122 from the air inlet side of the air inlet channel 1223, so as to cover the axial extension range of the air inlet channel 1223, thereby improving the separation effect of the internal space of the air inlet channel 1223.

[0185] Optionally, the first separation plate is a straight line plate or a non-straight line plate. Further, the non-straight line plate includes a curved shape, a broken line shape, or the like, or is formed by one or more straight line segments and / or one or more curved line segments.

[0186] In some embodiments, the second separation part is arranged in the air inlet cavity 11 and can separate the air inlet cavity 11 into a first sub-air inlet cavity 115 and a second sub-air inlet cavity 116. Optionally, the first sub-air inlet cavity 115 corresponds to the first air inlet area, so that the air flow of the first sub-air inlet cavity 115 flows to the first air inlet area, and the second sub-air inlet cavity 116 corresponds to the second air inlet area, so that the air flow of the second sub-air inlet cavity 116 flows to the second air inlet area. In this way, through the cooperation of the second separation part and the first separation part, the fresh air flow and the dirty air flow can maintain the separated state of the air flow path during the flow through the air inlet cavity and the fan cavity, thereby improving the shunt air supply effect.

[0187] In the embodiment, the second separation part includes a second separation plate, the plate body of which is formed in the longitudinal direction from one side cavity wall to the other side cavity wall of the air inlet cavity 11. Optionally, the second separation plate is a separation plate as shown in the foregoing embodiment. Figures 3a to 3e ​

[0188] Alternatively, the second partition plate is consistent with the extension track of the plate body of the first partition plate, so as to ensure the consistency and smoothness of the partition surface formed by the second partition plate and the first partition plate. Here, the second partition plate has the same or different extension length as the plate body of the first partition plate. For example, when the cavity space of the air inlet cavity 11 is larger than the caliber of the air inlet passage 1223, the extension length of the plate body of the first partition plate is smaller than that of the second partition plate. In this case, the first partition plate is consistent with the partial plate body extension track of the second partition plate.

[0189] In some embodiments, the second partition plate and the first partition plate are integrally formed, which can effectively ensure the stability of the connection between the two partition plates and prevent additional air leakage gaps from being formed between the two partition plates.

[0190] In some embodiments, the fresh air module further includes an air outlet group, which includes a first air outlet and a second air outlet. Here, 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 air inlet area, and the second air outlet corresponds to the second air inlet area. Under the partitioning effect of the second partition plate and the rotation of the fan cavity, the airflow of the first air inlet area is deflected to flow to the first air outlet, and the airflow of the second air inlet area is deflected to flow to the second air outlet. Alternatively, the first air outlet is the first volute air outlet 124 in the foregoing embodiments, and the second air outlet is the second volute air outlet 125.

[0191] In some alternative embodiments, at least part of the body of the impeller driver 126 is located in the air inlet passage 1223 of the impeller 122. Accordingly, the first partition plate is formed with a recess for avoiding the impeller driver 126, so as to avoid positional interference between the first partition plate and the impeller driver 126 during rotation.

[0192] Here, the recess is arranged in a spaced manner with 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 of the two air inlet areas in the air inlet passage 1223 through the gap.

[0193] In some alternative embodiments, in combination with Figure 9 As shown, the module shell 10 has an outdoor air inlet 114 which communicates the air inlet cavity 11 and the outdoor side. Specifically, the outdoor air inlet 114 is communicated with at least one of the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116, so that the outdoor fresh air in the outdoor side environment can be introduced into at least one of the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116.

[0194] Here, the number of sub-inlet air cavities 11 connected by the outdoor air inlet 114 is dynamically adjusted according to the working state of the fresh air module 1, for example, in the full fresh air mode, the outdoor air inlet 114 simultaneously connects the first sub-inlet air cavity 115 and the second sub-inlet air cavity 116; in the bidirectional air exchange mode, the outdoor air inlet 114 is only connected to one of the first sub-inlet air cavity 115 and the second sub-inlet air cavity 116, and the other is not connected.

[0195] Optionally, the outdoor air inlet 114 is arranged on the cavity wall of the inlet air cavity 11 adjacent to the first sub-inlet air cavity 115 and the second sub-inlet air cavity 116, so as to adjust the switching of multiple connection forms. For example, the outdoor air inlet 114 can be arranged on the outer cavity wall 1115, the first side wall 1111 or the second side wall 1112. Here, the common point of the outer cavity wall 1115, the first side wall 1111 or the second side wall 1112 is that each side wall has at least part of the wall surface located adjacent to one side of the first sub-inlet air cavity 115, and at least another part of the wall surface is located adjacent to one side of the second sub-inlet air cavity 116. For example, in combination with Figure 9 As shown, the outdoor air inlet is arranged on the second side wall 1112 of the inlet air cavity 11 and located adjacent to the first sub-inlet air cavity 115. In this embodiment, the fresh air mode is in the bidirectional air exchange mode, and the outdoor air inlet 114 is connected to the first sub-inlet air cavity 115 and not connected to the second sub-inlet air cavity 116.

[0196] Optionally, the shape of the outdoor air inlet 114 is circular, rectangular, square, etc., which is not limited in the present application.

[0197] In still other optional embodiments, in combination with Figure 10 As shown, the module housing 10 has an indoor return air inlet 113 connected to the inlet air cavity 11 and the indoor side. Specifically, the indoor return air inlet 113 is connected to at least one of the first sub-inlet air cavity 115 and the second sub-inlet air cavity 116, so that the indoor dirty air in the indoor side environment can be introduced into at least one of the first sub-inlet air cavity 115 and the second sub-inlet air cavity 116.

[0198] Here, the number of sub-inlet air cavities 11 connected by the indoor return air inlet 113 is dynamically adjusted according to the working state of the fresh air module 1, for example, in the bidirectional air exchange mode, the indoor return air inlet 113 is only connected to one of the first sub-inlet air cavity 115 and the second sub-inlet air cavity 116, and the other is not connected; in the full return air mode, the indoor return air inlet 113 simultaneously connects the first sub-inlet air cavity 115 and the second sub-inlet air cavity 116.

[0199] Optionally, the indoor return air outlet 113 is formed on the cavity wall of the air inlet cavity 11 adjacent to the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116, so as to be adjusted in switching with the plurality of communication modes. For example, the indoor return air outlet 113 can be formed on the outer cavity wall 1115, the first side wall 1111 or the second side wall 1112, wherein the common point of the outer cavity wall 1115, the first side wall 1111 or the second side wall 1112 is that each side wall has at least part of the wall surface located adjacent to one side of the first sub-air inlet cavity 115, and at least another part of the wall surface located adjacent to one side of the second sub-air inlet cavity 116. For example, as shown in FIG. 1, the indoor return air outlet 113 is formed on the second side wall 1112 of the air inlet cavity 11, and located adjacent to the second sub-air inlet cavity 116. In this embodiment, the fresh air mode is in the bidirectional air exchange mode, and the indoor return air outlet 113 is in communication with the second sub-air inlet cavity 116, and not in communication with the first sub-air inlet cavity 115. Figure 11 For example, as shown in FIG. 1, the indoor return air outlet 113 is formed on the second side wall 1112 of the air inlet cavity 11, and located adjacent to the second sub-air inlet cavity 116. In this embodiment, the fresh air mode is in the bidirectional air exchange mode, and the indoor return air outlet 113 is in communication with the second sub-air inlet cavity 116, and not in communication with the first sub-air inlet cavity 115.

[0200] Optionally, the shape of the indoor return air outlet 113 is circular, rectangular, square, etc., which is not limited in the present application.

[0201] In some optional embodiments, the fresh air module 1 further comprises a return air switch part, which is arranged at the indoor return air outlet 113, and is used to controllably close or open the indoor return air outlet 113. Optionally, the return air switch part is configured to at least close the indoor return air outlet 113 in the full fresh air mode, so that the indoor dirty air on the indoor side is not introduced into the air inlet cavity 11; and open the indoor return air outlet 113 in the bidirectional air exchange mode, so that the indoor dirty air on the indoor side flows into the air inlet cavity 11 through the indoor return air outlet 113 under the driving of the negative pressure air force of the impeller 122.

[0202] Here, the return air switch part comprises a return air baffle and a first driver, and the return air baffle is in driving connection with the first driver, so that the return air baffle is driven to close or open the indoor return air outlet 113.

[0203] Optionally, the return air baffle is slidably arranged at the indoor return air port 113 relative to the second side wall 1112, one side edge of the return air baffle is provided with a first rack, the first rack is longitudinally extended along the side edge; the first driver includes a first driving motor and a first gear, the first gear is sleeved on the driving shaft of the first driving motor and is arranged in meshing with the first rack. In this way, by controlling the first driving motor to rotate bidirectionally, the return air baffle is driven by the cooperation of the first gear and the first rack to move towards the direction close to the indoor return air port 113 or to move towards the direction away from the indoor return air port 113. When moving towards the direction close to the indoor return air port 113, the return air baffle can cover the indoor return air port 113 to close the indoor return air port 113; and when moving towards the direction away from the indoor return air port 113, the return air baffle is away from the position covering the indoor return air port 113 to open the indoor return air port 113.

[0204] Further optionally, the return air baffle is pivotally connected to one side edge of the indoor return air port 113, the first driver includes a first driving motor and a pivot shaft, the return air baffle is arranged on the pivot shaft. In this way, by controlling the first driving motor to drive the return air baffle to perform a flipping action, the return air baffle can close or open the indoor return air port 113.

[0205] In an optional embodiment, the outdoor air port 114 and the indoor return air port 113 are both arranged on the second side wall 1112 of the air inlet cavity 11 and are respectively located on two sides of the partition plate 15, wherein the outdoor air port 114 is located on the side of the partition plate 15 corresponding to the first sub-air inlet cavity 115, and the indoor return air port 113 is located on the side of the partition plate 15 corresponding to the second sub-air inlet cavity 116, as shown in Figure 11

[0206] In some optional embodiments, as shown in Figure 12 In the embodiment, the fresh air pipe 20 has a first air pipe passage 231 and a second air pipe passage 232 which are separately arranged and are used for respectively introducing outdoor fresh air from the outdoor side to the outdoor air port 114 of the module housing 10.

[0207] Exemplarily, as shown in

[0208] Figure 13 ​​As shown, the duct body 21 is internally provided with a duct partition plate 213, which is formed in extension along the longitudinal direction of the duct body 21, and separates the duct body 21 into two relatively independent duct body 21 passages, including a first duct body passage 211 and a second duct body passage 212. Similarly, the pipe joint 22 is internally provided with a joint partition plate 223, which is formed in extension along the pipe route of the pipe joint 22, specifically from the end of the pipe joint 22 connected to the duct body 21 to the end of the pipe joint 22 connected to the outdoor air inlet 114, and separates the pipe joint 22 into two relatively independent joint passages, including a first joint passage 221 and a second joint passage 222. At the same time, the joint partition plate 223 corresponds to the position of the duct partition plate 213, so that the first duct body passage 211 and the first joint passage 221 jointly form a first duct passage 231, and the second duct body passage 212 and the second joint passage 222 jointly form a second duct passage 232. Optionally, the outdoor air inlet 114 of the module housing 10 is also provided with a partition piece, which can be used to divide the outdoor air inlet 114 into independent air inlet paths corresponding to the two joint passages of the pipe joint 22.

[0209] Optionally, the duct partition plate 213 separates the duct body 21 into two passages with the same cross-sectional area, for example, the cross section of the duct body 21 is circular, and in the cross-sectional view, the duct partition plate 213 is formed in extension along a radial line of the duct body 21, as shown. Figure 13a In this embodiment, the two duct body 21 passages can achieve equal air volume delivery for air supply, for example, in the bidirectional air exchange mode, the two duct body 21 passages deliver outdoor fresh air and indoor dirty air respectively, and the outdoor fresh air induction volume is substantially the same as the indoor dirty air exhaust volume, ensuring the stability of indoor air pressure during the operation of the fresh air module 1.

[0210] Alternatively, the duct partition plate 213 separates the duct body 21 into two passages with different cross-sectional areas, for example, the cross section of the duct body 21 is circular, and in the cross-sectional view, the duct partition plate 213 is formed in extension along a straight line at an angle with the radial line of the duct body 21, as shown. Figure 13b Alternatively, the duct partition plate 213 is a non-straight plate, such as an arc-shaped plate, a broken line-shaped plate, etc., which can also achieve unequal separation of the space of the duct body 21. In this embodiment, the two duct body 21 passages can achieve unequal air volume delivery for air supply, for example, in the bidirectional air exchange mode, the cross-sectional area of the first duct body passage 211 is larger than that of the second duct body passage 212, so that the outdoor fresh air induction volume corresponding to the first duct body passage 211 is larger than the indoor dirty air exhaust volume corresponding to the second duct body passage 212, which can achieve positive pressure air supply effect for the indoor side environment.

[0211] In some other embodiments, the indoor end of the first duct channel 231 is defined as the first fresh air outlet 2311, and the indoor end of the second duct channel 232 is divided into the second fresh air outlet 2321 and the branch outlet 2322.

[0212] The first fresh air outlet 2311 and the second fresh air outlet 2321 are connected to the outdoor air outlet 114 of the module housing 10, so that the outdoor fresh air from the first fresh air outlet 2311 and the second air duct channel 232 flows to the outdoor air outlet 114 through the second fresh air outlet 2321.

[0213] Furthermore, the branch port 2322 connects the indoor air outlet and the air outlet side of the air inlet chamber 11. It can be used to direct at least a portion of the air output from the air outlet side of the air inlet chamber 11 to the second duct channel 232 via the branch port 2322, thereby discharging this portion of air to the outdoor side. In conjunction with the previous embodiment, since the fan chamber 12 is located on the air outlet side of the air inlet chamber 11, the branch port 2322 connects the volute air outlet of the fan chamber 12 and the indoor air outlet of the module housing 10. Thus, the air output from the volute air outlet can flow to one or both of the indoor air outlet and the branch port 2322. Figure 15 As shown, the branch port 2322 is located near the lower part of the module housing 10. Therefore, in order to save on the length of the pipe material, the branch port 2322 is connected between the second volute air outlet 125 of the fan cavity 12 and the second indoor air outlet 52 of the module housing 10.

[0214] exist Figure 14 and 14a In the illustrated embodiment, the first fresh air outlet 2311, the second fresh air outlet 2321, and the branch outlet 2322 are installed on the pipe joint 22 of the fresh air duct 20.

[0215] In some optional embodiments, the fresh air module 1 further includes a duct switch unit disposed at the location of the second fresh air outlet 2321. The duct switch unit is used to controllably open or close the second fresh air outlet 2321. Optionally, the duct switch unit is configured to open the second fresh air outlet 2321 at least in the fresh air mode, so that the second duct passage 232 is connected to the outdoor air outlet 114, allowing outdoor fresh air to flow into the air inlet chamber 11; and to close the second fresh air outlet 2321 in the bidirectional ventilation mode, so that the second duct passage 232 is blocked from the outdoor air outlet 114.

[0216] Here, the duct switch includes a duct baffle and a second actuator. The duct baffle is driven to be connected to the second actuator, so that the duct baffle is driven to close or open the second fresh air outlet 2321.

[0217] Optionally, the air duct baffle is slidably arranged at the second fresh air outlet air duct opening 2321 relative to the second side wall 1112, one side edge of the air duct baffle is provided with a second rack, the second rack is formed in extension along the longitudinal direction of the side edge; the second driver includes a second driving motor and a second gear, the second gear is sleeved on the driving shaft of the second driving motor and is arranged in meshing with the second rack. In this way, by controlling the bidirectional rotation of the second driving motor, the air duct baffle is driven by the cooperation of the second gear and the second rack to move towards the direction close to the second fresh air outlet air duct opening 2321 or to move away from the direction of the second fresh air outlet air duct opening 2321. When moving towards the direction close to the second fresh air outlet air duct opening 2321, the air duct baffle can cover the indoor return air opening 113 to close the second fresh air outlet air duct opening 2321; and when moving away from the direction of the second fresh air outlet air duct opening 2321, the air duct baffle is away from the position covering the second fresh air outlet air duct opening 2321 to open the second fresh air outlet air duct opening 2321.

[0218] Further optionally, the air duct baffle is pivotally connected to one side edge of the second fresh air outlet air duct opening 2321, the second driver includes a second driving motor and a pivot shaft, and the air duct baffle is arranged on the pivot shaft. In this way, by controlling the second driving motor to drive the air duct baffle to perform a flipping action, the air duct baffle can close or open the second fresh air outlet air duct opening 2321.

[0219] In the foregoing Figure 11 In the embodiment shown, since the outdoor air inlet opening 114 (second fresh air outlet air duct opening) and the indoor return air opening 113 are both arranged on the second side wall 1112 of the air inlet cavity 11 and are arranged adjacent to each other, in this embodiment, the outdoor air inlet opening 114 (second fresh air outlet air duct opening) and the indoor return air opening 113 can share the same switching component, and the switching of the respective closed / open states of the second fresh air outlet air duct opening and the indoor return air opening 113 is realized simultaneously by using the same switching component, which can effectively simplify the number of switching components and the complexity of the module structure.

[0220] Specifically, in combination with Figure 16 and 16a As shown, the fresh air module 1 further includes an integrated switch 40 arranged on the second side wall 1112 where the outdoor air inlet opening 114 and the indoor return air opening 113 are located, and configured to at least open the second fresh air outlet air duct opening 2321 and close the indoor return air opening 113 in the full fresh air mode, and close the second fresh air outlet air duct opening 2321 and open the indoor return air opening 113 in the bidirectional air exchange mode.

[0221] In combination with Figure 16As shown, the integrated switch part 40 comprises a baffle plate 41 and an integrated driver. The baffle plate 41 is slidably arranged on the second side wall 1112 of the air inlet cavity 11. The integrated driver is drivingly connected with the baffle plate 41, and is configured to at least drive the baffle plate 41 to move between a first sliding position and a second sliding position. When the baffle plate 41 is located at the first sliding position, the baffle plate 41 opens the first fresh air outlet port 2311 and the second fresh air outlet port 2321, and blocks the indoor return air port 113, as shown in Figure 17a ; and when the baffle plate 41 is located at the second sliding position, the baffle plate 41 blocks the second fresh air outlet port 2321, and opens the indoor return air port 113 and the first fresh air outlet port 2311, as shown in Figure 17b . Here, the first sliding position is located at a position of the second side wall 1112 close to the second sub-air inlet cavity 116, and the second sliding position is located at a position of the second side wall 1112 close to the first sub-air inlet cavity 115.

[0222] Optionally, one side edge (or side surface) of the baffle plate 41 is provided with a baffle rack 42 extending along the longitudinal direction of the side edge. The integrated driver comprises an integrated driving motor 43 and an integrated gear 44, the integrated gear 44 is sleeved on the driving shaft of the integrated driving motor 43 and is arranged in meshing with the baffle rack 42. In this way, by controlling the bidirectional rotation of the integrated driving motor 43, the baffle plate 41 is driven to move to the first sliding position or the second sliding position by the cooperation of the integrated gear 44 and the baffle rack 42.

[0223] In some other optional embodiments, the integrated driver is further configured to move close to or away from a third sliding position. When the baffle plate 41 is located at the third sliding position, the baffle plate 41 completely blocks the outdoor air port 114, so that the first air duct passage 231 and the second air duct passage 232 are both in a blocked state with the air inlet cavity 11, and the indoor return air port 113 is in an open state, as shown in Figure 17c .

[0224] In Figure 17c , the third sliding position is located on the other side of the second sliding position away from the first sliding position. When the baffle plate 41 is located at the third sliding position, outdoor fresh air cannot be introduced into the air inlet cavity 11, and only indoor air is transported to the air inlet cavity 11 through the indoor return air port 113.

[0225] In some optional embodiments, the partition plate 15 is of a split structure, which comprises a first partition plate 154 and a second partition plate 155 connected along the longitudinal direction of the plate body, as shown in Figures 17a to 17cOptionally, the first partition plate 154 is composed of the first arc plate segment 151 and the intermediate arc plate segment 153 in the previous embodiment, and the second partition plate 155 is composed of the second arc plate segment 152; or, the first partition plate 154 is composed of the first arc plate segment 151, and the second partition plate 155 is composed of the second arc plate segment 152 and the intermediate arc plate segment 153.

[0226] Here, the first partition plate 154 is fixed in the air inlet cavity 11. The second partition plate 155 is arranged on the air baffle 41 of the integrated switch part 40, and the second partition plate 155 can slide synchronously with the air baffle 41. In the present embodiment, the bottom end of the second partition plate 155 is fixed on the side of the air baffle 41 facing the air inlet cavity 11. Optionally, the second partition plate 155 is in an integral structure with the air baffle 41, or the bottom end of the second partition plate 155 is fixed on the corresponding side of the air baffle 41 by means of gluing, welding, etc.

[0227] Specifically, when the air baffle 41 moves to the first sliding position, the first partition plate 154 and the second partition plate 155 are staggered, and the second partition plate 155 moves into the cavity space of the second sub-air inlet cavity 116, so that the area originally separated and shielded by the second partition plate 155 is opened, and thus the fresh air pipe 20 is in communication with the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116, and outdoor fresh air can flow to the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116 at the same time. When the air baffle 41 moves to the second sliding position, the first partition plate 154 and the second partition plate 155 are connected, and the first partition plate 154 and the second partition plate 155 simultaneously play the role of separating the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116, so that the fresh air pipe 20 is only in communication with the first sub-air inlet cavity 115 through the outdoor air port 114, and the fresh air pipe 20 is blocked from the second sub-air inlet cavity 116.

[0228] When the air baffle 41 moves to the third sliding position, the first partition plate 154 and the second partition plate 155 are staggered, and the second partition plate 155 moves into the cavity space of the first sub-air inlet cavity 115, so that the area originally separated and shielded by the second partition plate 155 is opened, and thus the indoor air return port 113 is in communication with the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116, and indoor air can flow to the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116 at the same time.

[0229] In some optional embodiments, the air inlet switch part 10 is combined with the air outlet switch part 30. Figures 18 to 18b As shown in FIGS. 22, the fresh air module 1 further comprises an air outlet switching part 30 (air outlet switching mechanism) arranged at the communication position of the branch pipe port 2322, the second indoor air outlet 52, and the air outlet side of the air inlet cavity 11. The air outlet switching part 30 can be used to switch controllably, so that the air outlet side of the air inlet cavity 11 is in communication with one of the branch pipe port 2322 and the second indoor air outlet 52, and the other is blocked.

[0230] In conjunction with the previous embodiment, the fan cavity 12 is located on the air outlet side of the air inlet cavity 11, and the second indoor air outlet 52 is connected to the fan cavity 12. Therefore, in this embodiment, the air outlet switching unit 30 is configured to switch between at least a 100% fresh air state and a bidirectional air exchange state; wherein, in the 100% fresh air state, the air path between the fan cavity 12 and the second indoor air outlet 52 is connected, while the air path between the fan cavity 12 and the branch pipe 2322 is blocked; in the bidirectional air exchange state, the air path between the fan cavity 12 and the branch pipe 2322 is connected, while the air path between the fan cavity 12 and the second indoor air outlet 52 is blocked.

[0231] Combination Figure 18b As shown, the air outlet switching unit 30 includes a switching housing 31 and an air plug assembly.

[0232] The internal structure of the switching housing 31 includes a switching air chamber, a switching air inlet 311, a first switching air outlet 312, and a second switching air outlet 313 communicating with the switching air chamber. The switching housing 31 is installed on the fan volute 121, with the switching air inlet 311 connected to the second volute air outlet 125 of the fan volute 121. The first switching air outlet 312 is connected to the branch pipe 2322 of the second duct channel 232. The second switching air outlet 313 can be used as the "second indoor air outlet 52" mentioned above.

[0233] Optionally, the airlock assembly includes an airlock block 32 and an airlock motor 33, such as Figure 19 As shown. The air block 32 is rotatably disposed within the switching air chamber; the air block motor 33 is driven and connected to the air block 32, and is configured to at least drive the air block 32 to move between a first rotational position and a second rotational position. The first rotational position corresponds to a 100% fresh air state. When the air block 32 is in the first rotational position, it blocks the first switching air outlet 312 (branch pipe 2322), so that the switching air inlet 311 is only connected to the second switching air inlet 311 (second indoor air outlet 52), as shown. Figure 20a As shown. The second rotation position corresponds to the bidirectional ventilation state. When the air block 32 is in the second rotation position, it blocks the second switching air outlet 313 (second indoor air outlet 52), so that the switching air inlet 311 is only connected to the first switching air inlet 311 (branch pipe 2322), as shown. Figure 20b As shown.

[0234] In some alternative embodiments, the switching air inlet 311, the first switching air outlet 312, and the second switching air outlet 313 are arranged at intervals on the switching housing 31 along the outer periphery of the rotation axis of the air block 32. For example, combined with Figure 20a and 20bAs shown, the switching air inlet 311 is located at the upper side of the rotation axis, the first switching air outlet 312 is located at the right side of the rotation axis, and the second switching air outlet 313 is located at the lower left side of the rotation axis. In this way, the air block 32 can be switched among the multiple set rotation positions during rotation around the outer circumferential direction of the rotation axis.

[0235] Optionally, the switching housing 31 comprises a circular cavity 314, and the outer circumferential surface of the circular cavity 314 has arc-shaped openings corresponding to the switching air inlet 311, the first switching air outlet 312, and the second switching air outlet 313, respectively.

[0236] In combination Figure 18a and 21a As shown, the air block 32 comprises a central rotation shaft 321 and an air block baffle 322. The central rotation shaft 321 is coaxially arranged at the center of the circular cavity 314 and is drivingly connected with the air block motor 33 arranged at an axial outer side of the switching housing 31. The air block baffle 322 is fixedly connected with the central rotation shaft 321, so that the air block motor 33 can drive the central rotation shaft 321 to rotate the air block baffle 322 in the circular cavity 314.

[0237] Optionally, the air block baffle 322 comprises an arc-shaped plate member 3221 and a support plate 3222. The arc-shaped plate member 3221 is formed along the circumferential line of the circular cavity 314, and the curvature of the arc-shaped plate member 3221 is greater than or equal to the curvature of each arc-shaped opening, so as to block any arc-shaped opening during rotation. The support plate 3222 is used to connect the central rotation shaft 321 and the air block baffle 322, and is configured as a sector-shaped piece with the plate surface extending radially from the central rotation shaft 321. The outer extension circular arc edge of the support plate 3222 is fixedly connected with the air block baffle 322, and the center of the circular arc is fixedly connected with the central rotation shaft 321, as shown. Figure 19a

[0238] In some optional embodiments, the number of support plates 3222 is one, which is fixed to one end of the central rotation shaft 321, such as the left end or the right end of the central rotation shaft 321. A single support plate 3222 can effectively reduce the overall weight of the air block baffle 322, thereby reducing the operating power consumption of the air block motor 33. In yet other optional embodiments, the number of support plates 3222 is two, which are symmetrically fixed to both ends of the central rotation shaft 321. In this embodiment, the two support plates 3222 can provide support to the axial two side edges of the arc-shaped plate member 3221, preventing the air block baffle 322 from being deflected under the action of wind pressure, and ensuring the air blocking effect of the air block baffle 322 in the switching air chamber.

[0239] Optionally, the motor housing of the air block motor 33 is provided with a fixed lug plate 331, and the fixed lug plate 331 is provided with a threaded hole, as shown. Figure 19b ​As shown; the outer wall of the circular cavity 314 is provided with a fixing seat 315, as shown. Figure 21 The air block motor 33 is assembled in the circular cavity 314 through the fixing lug plate 331 and the fixing seat 315.

[0240] In yet some alternative embodiments, the second air duct passage 232 can be replaced by another separate exhaust air duct, that is, the first air duct passage 231 is used as the fresh air duct 20 alone for conveying outdoor fresh air to the indoor side; the exhaust air duct is used to replace the second air duct passage 232, which can be used at least for discharging indoor exhaust air to the outdoor side. Here, the exhaust air duct has an indoor port on the indoor side and an outdoor port on the outdoor side, wherein the indoor port is communicated with the first switching outlet of the air outlet switching mechanism. After the indoor exhaust air enters the module housing 10 from the indoor return air port 113, it successively passes through the air inlet cavity 11, the fan cavity 12, and the switching air cavity, and then flows to the exhaust air duct, and finally is discharged to the outdoor side through the exhaust air duct.

[0241] In embodiments, the exhaust air duct and the indoor air outlet are arranged at a certain distance apart, and accordingly, in combination with Figure 18a As shown, the switching air cavity further comprises an outwardly extending cavity, which extends from the circular cavity 314 to the side of the exhaust air duct (the second air duct passage 232) to communicate the circular cavity 314 and the indoor port (the branch port 2322) of the exhaust air duct (the second air duct passage 232). The extension distance of the outwardly extending cavity is adapted to the interval distance of the exhaust air duct relative to the indoor air outlet.

[0242] The foregoing embodiments show that the partition plate 15 is fixed in the internal space of the air inlet cavity 11, and the relative position of the partition plate 15 and the air inlet cavity 11 is unchangeable, which makes the cavity space of the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116 also basically fixed. This limits the application range of the fresh air module and cannot meet the functional enhancement requirements of users, for example, in the case where the air quality difference between indoor and outdoor environments is not large, but the temperature difference is large, some users may wish to appropriately reduce the input of outdoor fresh air to reduce the disturbance of outdoor fresh air to indoor temperature. In view of the above situation, in yet some alternative embodiments, the partition component arranged in the fresh air module 1 is designed in a movable form, so that the partition component can move relative to the internal cavity of the module housing 10, and in the moving process, the cavity space of the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116, thereby achieving the effect of changing the outdoor fresh air volume conveyed by the first sub-air inlet cavity 115 and / or the indoor exhaust air volume conveyed by the second sub-air inlet cavity 116.

[0243] In some embodiments, the partition component is movably arranged in the air inlet cavity 11 of the module housing 10, and can be controlled to adjust the relative position with the air inlet cavity 11 to change the cavity space of the first and second sub-air inlet cavities 115 and 116. In the embodiment of the present disclosure, the fresh air module 1 movably arranges the partition component in the air inlet cavity 11, so that during the movement of the partition component, the cavity space of the first and second sub-air inlet cavities 115 and 116 formed by the partition component can be changed, thereby achieving the effect of adjusting the fresh air inlet volume and the dirty air outlet volume.

[0244] Optionally, the partition component is in the form of rotation, sliding or the like relative to the air inlet cavity 11 to adjust the relative position with the air inlet cavity 11.

[0245] Here, the air inlet cavity outlet 112 is provided on the air outlet cavity wall 1116, and the partition component can divide the air inlet cavity outlet 112 into a first sub-outlet and a second sub-outlet, which correspond to the first and second sub-air inlet cavities 115 and 116, respectively, as the airflow output path of the two sub-air inlet cavities to the fan cavity 12. In this way, during the rotation, sliding or the like movement of the partition component relative to the air inlet cavity 11, the relative position of the partition component with the air inlet cavity outlet 112 can be changed, so that the partitioning boundary position of the first and second sub-outlets by the partition component is changed, thereby achieving the effect of changing 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.

[0246] Specifically, in some optional embodiments, in combination with Figures 22a to 22c 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 to adjust the relative position with the air inlet cavity 11. In this embodiment, the partition 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.

[0247] 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 1116. Optionally, 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 1116, i.e., the outer cavity wall 115 in the foregoing embodiment, and a through hole is provided 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 22d 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.

[0248] In an embodiment, the partition driving motor is a bidirectional rotation motor type, so as to selectively drive the movable partition 181 to rotate in a clockwise direction or an anticlockwise direction.

[0249] In the present embodiment, similar to the partition shown in the foregoing embodiments, the movable partition 181 and at least one part of the cavity wall of the air inlet cavity 11 form a first sub-air inlet cavity 115, and at least another part of the cavity wall of the air inlet cavity 11 form a second sub-air inlet cavity 116. In this way, when the movable partition 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 by the movable partition 181 can be changed.

[0250] In an optional embodiment, the longitudinal two ends of the movable partition 181 respectively extend to the two side walls of the corresponding air inlet cavity 11, such as the first side wall 1111 and the second side wall 1112 of the air inlet cavity 11 in the present embodiment, where the longitudinal two ends of the movable partition 181 are respectively defined as a first outer plate end and a second outer plate end. In addition, the transverse two side edges of the movable partition 181 respectively extend to the two side walls of the corresponding air inlet cavity 11, such as the air outlet cavity wall 1116 and the outer cavity wall 1115 of the air inlet cavity 11 in the present embodiment. Here, the longitudinal two ends and the transverse two side edges of the movable partition 181 are spaced apart from the respective corresponding side walls to leave a gap for rotation, so as to avoid the rotation of the movable partition 181 being hindered by the side walls of the air inlet cavity 11.

[0251] In combination with the foregoing embodiments, the second side wall 1112 is spaced apart to form the outdoor air inlet 114 and the indoor return air inlet 113, wherein the outdoor air inlet 114 is used to deliver outdoor fresh air to the first sub-air inlet cavity 115, and the indoor return air inlet 113 is used to deliver indoor dirty air to the second sub-air inlet cavity 116. Optionally, the rotation range of the movable partition 181 is limited to the longitudinal one end of the movable partition 181 corresponding to the second side wall 1112 being located between the outdoor air inlet 114 and the indoor return air inlet 113 at all times, so that the outdoor air inlet 114 always corresponds to the first sub-air inlet cavity 115, and the indoor return air inlet 113 always corresponds to the second sub-air inlet cavity 116.

[0252] Optionally, the air inlet cavity 11 is configured in the form of a cavity with a whole outer contour in a circular or approximately circular shape, 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 in the circumferential direction of the air inlet cavity 11.

[0253] Further optionally, the movable partition 181 is a straight line plate or a non-straight line plate. Optionally, the non-straight line 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.

[0254] In some alternative embodiments, the partition component further comprises one or more static partitions, which can cooperate with the dynamic partition 181 to jointly define the sub-inlet air cavities and / or the rotation region of the dynamic partition 181.

[0255] Specifically, in combination with Figure 22c as shown, the partition component comprises 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 inlet air cavity 11 where the outdoor air inlet 114 and the indoor return air outlet 113 are located, such as the second side wall 1112 in Figure 22c , and is extended towards the inner side of the inlet air 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 define the outdoor air inlet 114 within the spatial range of the first sub-inlet air cavity 115 and the indoor return air outlet 113 within the spatial range of the second sub-inlet air cavity 116. Alternatively, the second static partition 184 is arranged on the side wall opposite to the side wall where the first static partition 183 is arranged, such as the first side wall 1111 in Figure 22c , and is also extended towards the inner side of the wall of the inlet air cavity 11; the second static partition 184 can serve to separate the first sub-inlet air cavity 115 and the second sub-inlet air cavity 116.

[0256] In the present embodiment, the first static partition 183 and the second static partition 184 are arranged in a space therebetween, and the rotation region of the dynamic partition 181 is located in the space.

[0257] In this way, one side of the dynamic partition 181, one side of the first static partition 183, one side of the second static partition 184, and at least a part of the wall of the inlet air cavity 11 jointly define the first sub-inlet air cavity 115; here, the at least a part of the wall of the inlet air cavity 11 can comprise the outer wall 1115, the outlet air cavity wall 1116, the first side wall 1111, the second side wall 1112, and the fourth side wall 1114. In addition, the other side of the dynamic partition 181, the other side of the first static partition 183, the other side of the second static partition 184, and at least another part of the wall of the inlet air cavity 11 jointly define the second sub-inlet air cavity 116; here, the at least another part of the wall of the inlet air cavity 11 can comprise the outer wall, the outlet air cavity wall 1116, the first side wall 1111, the second side wall 1112, and the third side wall 1113.

[0258] Optionally, in combination with Figure 22cAs 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 its 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.

[0259] Similarly, combination Figure 22c 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 rotation range of the second outer plate end.

[0260] Optionally, the arc lengths of the first arc segment 1832 and the second arc segment 1842 are approximately equal.

[0261] 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.

[0262] In some embodiments, the fresh air module further includes an air inlet group, which includes a first air inlet and a second air inlet.

[0263] 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.

[0264] 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.

[0265] 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 rotates 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 filtered from the second sub-air inlet cavity 116 to the indoor side.

[0266] Optionally, the first air outlet is a first volute air outlet 124, and the second air outlet is a second volute air outlet 125.

[0267] 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 a first position, the first position is a position where 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 124, 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 125, so that part of the fresh air flow of the first sub-air inlet cavity 115 is diverted to the second volute air outlet 125, and then output to the outdoor side through the second volute air outlet 125, as shown in FIG. 18B. Figure 22e Optionally, the first air outlet is a first volute air outlet 124, and the second air outlet is a second volute air outlet 125. Figure 22e Optionally, the first air outlet is a first volute air outlet 124, and the second air outlet is a second volute air outlet 125. Figure 22e Optionally, the first air outlet is a first volute air outlet 124, and the second air outlet is a second volute air outlet 125.

[0268] 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, and the part of the outdoor fresh air replaced is discharged to the outdoor side again, so that the amount of the outdoor fresh air output to the indoor side by the movable partition plate 181 in the first position is reduced.

[0269] 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. 18. Figure 22f As shown in FIG. 17, 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 124, 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 125, 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 124, 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 125.

[0270] Optionally, the proximal end of the first circular arc segment 1832 corresponds to the first volute tongue segment 1242, and / or the proximal end of the second circular arc segment 1842 corresponds to the second volute tongue segment 1252.

[0271] 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 air distribution effect of diversion is close to the fixed partition plate form in the foregoing embodiments.

[0272] 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 distribution position according to actual needs, so as to dynamically adjust the output proportion 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 124 gradually increases, and the proportion of the dirty air output through the second volute air outlet 125 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 124 gradually decreases, and the proportion of the dirty air output through the second volute air outlet 125 gradually decreases.

[0273] In the above embodiments, the air filter element 14 of the fresh air module 1 is in a strip shape and arranged in the air inlet cavity 11, and covers at least one of the first air inlet and the second air inlet, so as to filter and purify the air flow input through the first air inlet and / or the second air inlet.

[0274] In Figure 22bIn this embodiment, the air filter 14 is arranged at a position close to the second side wall 1112 of the air inlet cavity 11, so as to cover the outdoor air inlet 114 as the first air inlet and the indoor return air inlet 113 as the second air inlet.

[0275] In some other optional embodiments not shown in the drawings, the partition component comprises a movable partition and a partition driver, which can drive the movable partition to move laterally in the air inlet cavity.

[0276] Here, the movable partition is arranged to slide laterally in the air inlet cavity, and the lateral movement plane of the movable partition is parallel to the wall surface of the air outlet cavity wall. Optionally, one end of the movable partition is provided with a partition driving rack extending laterally, and the partition driver comprises a partition driving motor and a partition driving gear, which are engaged with each other, so that the partition driving motor can drive the movable partition to move reciprocatingly along the longitudinal direction of the partition driving rack. Here, the longitudinal direction of the partition driving rack is parallel to the longitudinal direction of the first side wall and the second side wall.

[0277] In the embodiments, the partition driving motor is a bidirectional rotation motor type, so as to selectively drive the movable partition to move in a first direction or a second direction laterally. Here, the first direction and the second direction are two opposite directions. Optionally, 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.

[0278] In the embodiments, similar to the partition shown in the foregoing embodiments, the movable partition and at least 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 form a second sub-air inlet cavity.

[0279] In addition, in order to ensure the air tightness between the two sub-air inlet cavities during the lateral movement of the movable partition, the air inlet cavity can be configured in the form of a square cavity, or 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. Thus, during the lateral 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, so as to reduce the air leakage gap that may be caused during the movement.

[0280] In this way, when the movable partition moves laterally in the air inlet cavity, the cavity space of the first sub-air inlet cavity and the second sub-air inlet cavity surrounded by the movable partition can be changed. For example, when the movable partition moves towards the third side wall, the cavity space of the first sub-air inlet cavity and the caliber of the corresponding first sub-air outlet increase, and the cavity space of the second sub-air inlet cavity and the caliber of the corresponding second sub-air outlet decrease. Alternatively, when the movable partition moves towards the fourth side wall, the cavity space of the first sub-air inlet cavity and the caliber of the corresponding first sub-air outlet decrease, and the cavity space of the second sub-air inlet cavity and the caliber of the corresponding second sub-air outlet increase.

[0281] In combination with the foregoing embodiments, the second side wall is provided with outdoor air inlets and indoor return air inlets at intervals, wherein the outdoor air inlets are used to deliver outdoor fresh air to the first sub-air inlet cavity, and the indoor return air inlets are used to deliver indoor dirty air to the second sub-air inlet cavity. Optionally, the transverse movement range of the movable partition is limited to a position corresponding to the longitudinal end of the second side wall, so that the outdoor air inlets are always corresponding to the first sub-air inlet cavity, and the indoor return air inlets are always corresponding to the second sub-air inlet cavity.

[0282] In the above-mentioned embodiments, the fresh air pipe 20 is connected to the first air inlet for introducing outdoor fresh air into the first air inlet cavity 11, and the second air pipe channel is connected to the second air outlet for discharging indoor dirty air to the outdoor side.

[0283] Optionally, the form of the partition shown in the foregoing embodiments for separating the air inlet channel 1223 of the impeller 122 can also be applied to the separation component in this embodiment, so that the separation component not only dynamically adjusts the sub-air inlet cavity space in the air inlet cavity 11 during movement, but also dynamically adjusts the channel space of the air inlet channel 1223 in the fan cavity 12, thereby enhancing the effect of distributing air from different sources.

[0284] In combination with the foregoing embodiments, the first partition plate 191 of the separation component is arranged in the air inlet channel 1223 of the impeller 122, and the second partition plate 192 of the separation component is the movable partition 181 in this embodiment. The first partition plate 191 is fixed to the movable partition 181 and can move together with the movable partition 181, as shown in Figure 22g Here, the first partition plate 191 is applied to the movable partition 181 scheme that moves in a rotating manner relative to the air inlet cavity 11.

[0285] Optionally, the partition driver 182 can be drivingly connected 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 air inlet cavity 11, so as to change the separation position of the first partition plate 191 relative to the air inlet channel 1223 and the separation position of the second partition plate 192 (movable partition 181) relative to the air inlet cavity 11.

[0286] 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 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 22h

[0287] ​Here, the avoidance groove 1911 is spaced apart from the impeller driver 126, and the gap between the groove edge and the impeller driver 126 is minimized to improve the air tightness effect and reduce the mixing of air flows in the two air inlet areas in the air inlet channel 1223 via the gap.

[0288] The following describes several air exchange modes of the fresh air module 1 in the form of the fresh air module 1 shown in the foregoing embodiments. (The outdoor fresh air is indicated by solid arrows, and the indoor polluted air is indicated by dashed arrows.)

[0289] Optionally, the working modes of the fresh air module 1 include a full fresh air mode. The full fresh air mode refers to the fresh air module 1 used for conveying outdoor fresh air from the outdoor side to the indoor side. In this mode, the fresh air module 1 does not convey indoor polluted air to the outdoor side. The full fresh air mode can supplement the outdoor fresh air with good air quality to the indoor side, thereby improving the air quality of the indoor side.

[0290] In some embodiments, in the full fresh air mode, the outdoor fresh air is conveyed to the indoor side via the fresh air pipe 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 rotation direction (such as the first rotation direction); the baffle 41 of the control integrated switch part 40 is moved to the first sliding position to block the indoor return air outlet 113, and the first air pipe passage 231 and the second air pipe passage 232 of the fresh air pipe 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 air block 32 of the air outlet switching mechanism is located at the first rotating position, so that the second air pipe passage 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.

[0291] In this way, the impeller 122 rotates to generate a negative pressure suction force on the air inlet cavity 11 side, attracting the outdoor fresh air on the outdoor side to flow to the indoor side through the first air pipe passage 231 and the second air pipe passage 232, and entering the air inlet cavity 11 through the outdoor air outlet 114 of the module shell 10, as shown by the arrow in Figure 23a and 23c The outdoor fresh air then flows from the air inlet cavity 11 to 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 23b .

[0292] Yet another optional working mode of the fresh air module 1 is a bidirectional air exchange mode. The bidirectional air exchange mode refers to the fresh air module 1 being used to simultaneously transport outdoor fresh air from the outdoor side to the indoor side and transport 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 synchronous replacement of fresh air and polluted air and improving indoor air quality more quickly.

[0293] In some embodiments, in the bidirectional air exchange mode, it is divided into an outdoor fresh air flow path and an indoor exhaust air flow path. Specifically, in the bidirectional air exchange mode, the impeller 122 is kept rotating in a set rotational direction (such as the first rotational direction); the baffle 41 of the integrated switch part 40 is controlled to move to the second sliding position to make the indoor return air outlet 113 open, and the second fresh air outlet pipe opening 2321 of the second air pipe passage 232 is blocked; the wind blocking block 32 of the air outlet switching mechanism is controlled to be located at the second rotating position, so that the branch pipe opening 2322 of the second air pipe 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 pipe passage 232.

[0294] In this way, the impeller 122 generates a negative pressure suction force on the side of the air inlet chamber 11 when rotating, 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 transported to the first indoor air outlet 51 in sequence through the first air pipe passage 231, the first sub-air inlet chamber 115, and the fan chamber 12, and the outdoor fresh air is sent into the indoor side environment through the first indoor air outlet 51, as shown by the arrow in FIG. 11. Figure 24a and 24c The indoor exhaust air flow path includes that the indoor polluted air is transported to the second air pipe passage 232 in sequence through the indoor return air outlet 113, the second sub-air inlet chamber 116, and the fan chamber 12, and the indoor polluted air is finally exhausted to the outdoor side through the second air pipe passage 232, as shown by the arrow in FIG. 12. Figure 24b and 24c

[0295] Yet another optional working mode of the fresh air module 1 is a full return air mode. The full return air mode refers to the fresh air module 1 being used to transport at least part of outdoor polluted air from the indoor side to the outdoor side, and / or filter and purify at least part of indoor polluted air and then send it back to the indoor side. In this mode, the fresh air module 1 does not transport outdoor fresh air to the indoor side. This mode can be applied to the case where the outdoor side environment air quality is also poor, such as smog weather.

[0296] ​In some embodiments, in the full return air mode, the indoor dirty air is delivered to the outdoor side via the indoor return air opening 113, the air inlet cavity 11, the fan cavity 12 and the second air duct passage 232 (dirty air duct), and / or the indoor dirty air is sent back to the indoor side via the indoor return air opening 113, the air inlet cavity 11, the fan cavity 12 and the first indoor air outlet 51. Specifically, in the full return air mode, the impeller 122 keeps rotating in a set rotational direction (e.g., the first rotational direction); the baffle 41 of the control integrated switch part 40 is moved to the third sliding position so that the outdoor air opening 114 is blocked and the indoor return air opening 113 is open; and the wind blocking block 32 of the air outlet switching mechanism is located in the first rotational position or the second rotational position.

[0297] 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 the indoor dirty air on the indoor side to enter the air inlet cavity 11 via the indoor return air opening 113 of the module housing 10 and is divided into two parts, one part flows into the first sub-air inlet cavity 115 and the other part flows into the second sub-air inlet cavity 116, as shown by the arrows in Figure 25a 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 the indoor dirty air on the indoor side to enter the air inlet cavity 11 via the indoor return air opening 113 of the module housing 10 and is divided into two parts, one part flows into the first sub-air inlet cavity 115 and the other part flows into the second sub-air inlet cavity 116, as shown by the arrows in Figure 25b and 25c .

[0298] 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 14, and then is delivered to the switching air cavity. Here, when the wind blocking block 32 is located in the first rotational 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 25b When the wind blocking block 32 is located in the second rotational position, the part of the indoor dirty air is discharged to the outdoor side environment from the second air duct passage 232, as shown in Figure 25c and 25d .

[0299] In some alternative embodiments, the present application also provides an air conditioner 6, which comprises an air conditioner body and a fresh air module 1 as in any of the preceding embodiments, as shown in Figure 26 and 26a .

[0300] Optionally, in combination with Figure 26 and 26a , the air conditioner 6 is a wall-mounted air conditioner. The air conditioner body comprises an indoor unit housing 61 and a heat exchange assembly and the fresh air module 1 arranged inside the indoor unit housing 61. Optionally, the heat exchange assembly is arranged in the middle and one side space of the indoor unit housing 61, and the fresh air module 1 is arranged in the other side space of the indoor unit housing 61.

[0301] Here, the heat exchange assembly includes an indoor heat exchange air duct, an indoor heat exchanger 62 and an indoor fan. The indoor heat exchange air duct has a heat exchange return air port and a heat exchange air outlet port. The indoor heat exchanger 62 and the indoor fan are arranged in the indoor heat exchange air duct, wherein the indoor heat exchanger 62 is used to exchange heat with the return air flow flowing through the indoor heat exchanger 62 air duct. The indoor fan is used to rotate to generate air power to drive the air flow to flow through the indoor heat exchange air duct.

[0302] At the same time, the indoor unit shell 61 is also provided with a first shell air outlet port 611, a second shell air outlet port 612 and a shell return air port 613. Among them, the first indoor air outlet port 51 of the fresh air module 1 corresponds to the position of the first shell air outlet port 611 and communicates with each other, and the second indoor air outlet port 52 corresponds to the position of the second shell air outlet port 612 and communicates with each other, so that the outdoor fresh air (or filtered indoor air) flowing through the fresh air module 1 can be sent into the indoor environment through the first shell air outlet port 611 and the second shell air outlet port 612. And the indoor return air port 113 of the fresh air module 1 corresponds to the position of the shell return air port 613 and communicates with each other, so that the indoor dirty air can flow into the fresh air module 1 through the shell return air port 613.

[0303] The above description and drawings sufficiently show the embodiments of the present disclosure to enable a person skilled in the art to practice them. Other embodiments can include structural and other changes. The embodiments only represent possible variations. Unless explicitly required, individual components and functions are optional, and the order of operations can be changed.
