Description

Technical Field

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

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

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

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

[0005] In the related product design, there is also a solution of a fresh air module with dual functions of outdoor fresh air and indoor exhaust. The interior of the fresh air module is divided into an air inlet chamber and a fan chamber. The air inlet chamber is divided into two sub-chambers by a partition plate. The two sub-chambers can be used to transport outdoor fresh air and indoor polluted air to the fan chamber respectively; and an impeller and two air outlet paths are set in the fan chamber. The impeller can drive the air flow and make the outdoor fresh air and indoor polluted air flow to different air outlet paths respectively. However, in actual use, it is found that a lot of outdoor fresh air and indoor polluted air are still mixed in the fan chamber, affecting the diversion and air supply effect of the fresh air module.

[0113] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0114] The present application provides a fresh air module 1, which can be applied to air conditioning equipment such as air conditioners (such as wall-mounted air conditioners), fresh air fans, humidifiers, etc., so as to controllably realize the functions of separately introducing outdoor fresh air, separately exhausting indoor polluted air, and / or simultaneously introducing outdoor fresh air and exhausting indoor polluted air, thereby improving indoor air quality and enhancing environmental comfort.

[0115] like Figure 1 and 1aAs shown, the fresh air module 1 mainly includes components such as a module housing 10, a fresh air duct 20 and an air outlet switching unit 30. The module housing 10 is internally constructed with an air cavity that limits the airflow path, and can be used as a space for accommodating components such as an air filter element 14 and a fan impeller 122. Here, the module housing 10 is provided with an indoor air outlet for communicating with the indoor side, and an outdoor air outlet 114 for communicating with the outdoor side. The indoor air outlet includes an indoor air outlet and / or an indoor return air outlet 113, the indoor air outlet is used as an air outlet for the fresh air module 1 to supply air to the indoor side, and the indoor return air outlet 113 is used as an air outlet for air to flow back from the indoor side to the fresh air module 1; the outdoor air outlet 114 is used as an air outlet for the fresh air module 1 to exhaust air to the outdoor side or for the outdoor side to transport fresh air to the fresh air module 1. The fresh air duct 20 extends from the indoor side to the outdoor side, and serves as a through-wall passage for introducing outdoor fresh air and / or exhausting indoor polluted air. The fresh air duct 20 is connected to the air cavity of the module housing 10, thereby jointly defining an outdoor fresh air introduction path and / or an indoor polluted air exhaust path. The air outlet switching unit 30 is provided on the air outlet side of the module housing 10, and is used to define the air outlet direction of at least part of the airflow flowing through the module housing 10, and the at least part of the airflow includes outdoor fresh air or indoor polluted air, and the air outlet direction includes flowing to the indoor side or the outdoor side, thereby realizing the functions of introducing outdoor fresh air and / or exhausting outdoor polluted air.

[0116] In some optional embodiments, combined with Figure 2 , 2a As shown in FIG. 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 connected to 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 and an air filter element 14, and the air inlet cavity 11 is connected to one or more of an indoor air outlet and an outdoor air outlet 114. The fan cavity 12 can be used to accommodate components such as an impeller 122, and the fan cavity 12 is connected to one or more of an indoor air outlet and an outdoor air outlet 114.

[0117] Optionally, the air inlet cavity 11 is located upstream of the wind path relative to the fan cavity 12, that is, the fan cavity 12 is located on the wind outlet side of the air inlet cavity 11, so that the flow direction of air from the air inlet cavity 11 to the fan cavity 12 is defined in the module housing 10. Alternatively, the air inlet cavity 11 is located downstream of the wind path relative to the fan cavity 12, that is, the air inlet cavity 11 is located on the wind outlet side of the fan cavity 12, so that the flow direction of air from the fan cavity 12 to the air inlet cavity 11 is defined in the module housing 10. Hereinafter, the former "the air inlet cavity 11 is located upstream of the wind path of the fan cavity 12" structure is mainly used as an example for explanation.

[0118] In some embodiments, in combination Figures 3a to 3eAs shown, the air inlet chamber 11 includes a first sub-air inlet chamber 115 and a second sub-air inlet chamber 116, and the two are separated and arranged, and the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116 respectively form a relatively independent air path, and the air flowing into the air inlet chamber 11 is divided into the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116, and is continuously transported to the fan chamber 12 along the respective air paths. Optionally, a partition component is provided in the air inlet chamber 11, and the partition component is used to separate the air inlet chamber 11 into the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116.

[0119] Optionally, the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116 can circulate air from the same wind source respectively, for example, the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116 are used to convey outdoor fresh air from the outdoor side at the same time, or are used to convey indoor polluted air from the indoor side at the same time. Alternatively, the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116 can circulate air from different wind sources respectively, for example, one of the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116 is used to convey outdoor fresh air from the outdoor side, and the other is used to convey indoor polluted air from the indoor side. Here, the partition component can at least be used to separate the air paths when the two sub-air inlet chambers 11 convey air from different wind sources, so as to block or slow down the mixing of air in different clean states.

[0120] Optionally, the overall outer contour of the air inlet cavity 11 is a flat cavity structure, which includes 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 FIG. 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 from each other, 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 peripheral 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 are jointly arranged to form the aforementioned air inlet cavity 11. Here, the two lateral sides (long sides) of each 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 to the corresponding side sides of the outer cavity wall 1115 and the air outlet cavity wall 1116, and the two longitudinal sides (short sides) are respectively connected to the short sides of other adjacent side walls.

[0121] In the embodiment, the first side wall 1111 and the second side wall 1112 are arranged opposite to each other, and the third side wall 1113 and the fourth side wall 1114 are arranged opposite to each other. 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 side position of the air inlet cavity 11, and is configured as the front side surface of the air inlet cavity 11; the fourth side wall 1114 is arranged at the rear side position of the air inlet cavity 11, and is configured as the back side surface of the air inlet cavity 11. In this example, the outer cavity wall 1115 serves as the left side surface of the air inlet cavity 11, and the air outlet cavity wall 1116 serves as the right side 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 the figure are both in the form of straight panels. Alternatively, 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 are non-straight panels, for example Figure 2b and 3b The board surface of the first side wall 1111 and the second side wall 1112 shown in the figure is a board surface form composed of multiple straight surface parts and / or curved surface parts spliced ​​together.

[0123] In this embodiment, part of the side wall is designed as a non-linear plate surface, which can achieve a more closely matched effect between the air inlet chamber 11 and other components of the fresh air module 1, thereby reducing the number of air leakage gaps and reducing wind path resistance. For example, the arc surface portion of the first side wall 1111 is adapted to the volute curve of the fan chamber 12, so that it is more closely connected with the corresponding position of the fan chamber 12, and the air tightness is better.

[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 an integrated structure, thereby reducing the existence of air leakage gaps and improving the sealing of the air inlet cavity 11 .

[0125] In an embodiment, in combination Figure 3c As shown, an air inlet cavity outlet 112 is provided on the air outlet cavity wall 1116, and the air inlet cavity 11 is connected to the fan cavity 12 through the air inlet cavity outlet 112. In this embodiment, the opening position and coverage range of the air inlet cavity 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 outlet 112.

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

[0127] Alternatively, the air inlet chamber outlet 112 is provided with an air outlet grille, which can not only intercept large debris (such as stones, paper balls, hair, etc.), but also has the effect of isolation and protection, so that the user's fingers will not accidentally extend into the fan chamber 12 when replacing the air filter 14, thereby preventing the user from being cut by the impeller 122 blades 1222.

[0128] Exemplarily, the air outlet grille includes one or more circumferential grille bars and one or more radial grille bars. Among them, the multiple circumferential grille bars are coaxially arranged and the radius gradually increases. The multiple circumferential grille bars are arranged radially from the inside to the outside on the same plane, and the plane is the plane where the air outlet 112 of the air inlet chamber is located. In addition, one end of each radial grille bar is connected to the central axis of the air outlet 112 of the air inlet chamber, and the other end is extended radially outward to form. The multiple radial grille bars are radially arranged at intervals at the air outlet 112 of the air inlet chamber and intersect with the circumferential grille bars. In this way, the circumferential grille bars and the radial grille bars are staggered to jointly achieve the function of interception and filtration.

[0129] In some optional embodiments, combined with Figure 3a and 3b As shown, the partition component includes a partition plate 15, which is arranged inside the air inlet cavity 11 and extends from one side wall of the air inlet cavity 11 to another opposite side wall. 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 partitions arranged front and back in space, namely the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116 mentioned above.

[0130] Exemplary, combined Figure 3c and 3dAs shown, the first sub-air inlet chamber 115 is located in the front space area of ​​the air inlet chamber 11, and is formed by the third side wall 1113, the front side of the partition plate 15, and the outer cavity wall 1115, the air outlet cavity wall 1116, the first side wall 1111 and the second side wall 1112, each of which is close to the front side; the second sub-air inlet chamber 116 is located in the rear space area of ​​the air inlet chamber 11, and is formed by the fourth side wall 1114, the back side of the partition plate 15, and the outer cavity wall 1115, the air outlet cavity wall 1116, the first side wall 1111 and the second side wall 1112, each of which is close to the rear side.

[0131] In the embodiment, the plate body extends transversely to the air outlet cavity wall 1116, which also divides the air inlet cavity air outlet 112 into a first sub-air outlet and a second sub-air outlet. The first sub-air inlet cavity 115 is connected to the first sub-air outlet, and the second sub-air inlet cavity 116 is connected to the second sub-air outlet.

[0132] Optionally, from the perspective of the longitudinal cross-section of the partition plate 15, the plate body line shape of the partition plate 15 is constructed as a straight line, a curve, a broken line, etc., or a plate body form composed of one or more straight lines, and / or, one or more curves. Here, the plate body line shape of the partition plate 15 can be adjusted according to factors such as the cavity volume distribution and wind resistance in the air inlet chamber 11. For example, in the case where the cavity volume of the first sub-air inlet chamber 115 is required to be greater than the cavity volume of the second sub-air inlet chamber 116, the partition plate 15 can be constructed as a curve or broken line with the plate surface protruding toward the second sub-air inlet chamber 116 to increase the space actually allocated to the first sub-air inlet chamber 115. Alternatively, in the case where the cavity volumes of the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116 are required to be approximately equal, the partition plate 15 can be constructed as a straight line and set at the midline position of the air inlet chamber 11 to achieve equal distribution of the space of the two sub-air inlet chambers 11.

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

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

[0135] Optionally, the air filter element 14 is disposed in one of the air inlet chamber 11 and the fan chamber 12. Figure 4 , 4aAs shown in FIG4b, the air filter 14 is disposed in the air inlet chamber 11, and can absorb and intercept air pollutants when the air flows through the air inlet chamber 11. This can not only effectively improve the air quality, but also reduce the wear of the fan impeller 122 caused by large particles such as gravel entering the fan chamber 12. In this embodiment, the air filter 14 is arranged close to the air outlet chamber wall 1116 of the air inlet chamber 11 to better fit and cover the air outlet 112 of the air inlet chamber, so that most of the air flowing to the air outlet 112 of the air inlet chamber can pass through the air filter 14 for purification and filtration.

[0136] The air filter 14 itself has an adsorption saturation limit. After the fresh air module 1 has been used for a long time, the air filter 14 gradually reaches its upper limit of adsorption capacity. At this time, the air filter 14 needs to be cleaned and replaced in time. In this way, in this embodiment, the air filter 14 is detachably arranged in the fresh air module 1, so that the user can disassemble and assemble the air filter 14 by himself when necessary. Optionally, the air filter 14 is retractably arranged in the air inlet chamber 11, and the user can pull out the dirty air filter 14 from the fresh air chamber, or push the brand new air filter 14 into the fresh air chamber.

[0137] Optionally, a socket 117 is provided on the outer wall of the air inlet chamber 11, and the air filter element 14 can be moved into / out of the air inlet chamber 11 via the socket 117. Here, in combination with the above-mentioned embodiment, the outer wall on 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 chamber 11. Figure 4b As shown, the third side wall 1113 of the air inlet chamber 11 is provided with the socket 117, and the third side wall 1113 is the side wall of the air inlet chamber 11 close to the front side and facing the user, so the position of the socket 117 allows the user to perform the pulling operation more conveniently. In this embodiment, the shape and size of the socket 117 are adapted to the cross-sectional shape and size of the air filter element 14.

[0138] In the above embodiment, the plate body of the partition plate 15 extends horizontally from the outer cavity wall 1115 to the air outlet cavity wall 1116, so the air filter element 14 inserted into the air inlet cavity 11 is also on the horizontal covering path of the plate body. In order to avoid the structural interference between the partition plate 15 and the air filter element 14, the partition plate 15 is provided with a slot 118 for the air filter element 14 to be pulled out. The slot 118 can be used to make the partition plate 15 avoid the air filter element 14, so that the two can be arranged in the air inlet cavity 11 without interfering with each other. Figure 4c shown.

[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. This ensures that the slot 118 does not block the movement of air in / out.

[0140] In some optional embodiments, the slot 118 is formed by being recessed along the axial direction of the air inlet cavity 11 from a side surface of the partition plate 15 corresponding to the air outlet cavity wall 1116, such as Figure 4c In the embodiment, 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. Exemplarily, the cross-sectional shape of the air filter element 14 is rectangular, and accordingly, the slot 118 is also configured as a rectangular groove.

[0141] Optionally, the groove 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 groove 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 prevented from being too large to affect the structural strength of the partition plate 15 itself. At the same time, since the air inside the air filter element 14 circulates freely and has no spatial separation effect, limiting the groove 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 chamber 11. Exemplarily, the groove depth of the slot 118 is l, and the axial length of the partition plate 15 is L, then the size design requirement of l≤L / 2 needs to be met.

[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 formed by protruding from the wall surface of the air outlet cavity wall 1116 toward the side of the outer cavity wall 1115, and can be cooperated with the partition plate 15 to form a slot 118. Figure 4d shown.

[0143] Combination Figure 4c and 4d The slot 118 provided on the partition plate 15 corresponds to one lateral side and two longitudinal 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 closeness of the air filter element 14 and one side of the air outlet cavity wall 1116, reduce the air leakage gap, and further enhance the spatial separation effect of the air inlet cavity 11 body.

[0144] In the embodiment, the separation rib 16 is consistent with the linear shape of the separation plate 15, and the positions in the axial direction overlap. In this way, the air flow path of the "separation plate 15-separation rib 16" part will not form an additional protrusion, and the flow path is smooth and smooth, avoiding the impact of wind resistance on the air. Exemplarily, the extension line shape of the separation plate 15 is a straight line, and the separation rib 16 is also adaptively constructed as a straight convex rib form; or, the extension line shape of the separation plate 15 is an arc line, and the separation rib 16 is adaptively constructed as an arc line convex rib form.

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

[0146] In this embodiment, the slot 118 includes a first slot edge, a second slot edge, a third slot edge and a fourth slot edge. Among them, the first slot edge is located at a side position close to the first side wall 1111, the second slot edge is located at a side position close to the second side wall 1112, the third slot edge is located at a side position close to the outer cavity wall 1115, and the fourth slot edge is located at a side position close to the air outlet cavity wall 1116. The four slot edges are jointly arranged to form the slot 118 for inserting the air filter element 14. Compared with the form in which the partition plate 15 and the partition rib 16 are jointly arranged to form the slot 118 in the previous embodiment, the present embodiment does not need to set the partition rib 16 on the air outlet cavity wall 1116, which simplifies the structure of the air inlet cavity 11.

[0147] In some embodiments, an elastic seal is provided on the inner periphery of the slot 118, and the elastic seal can be used to block the assembly gap between the slot 118 and the air filter element 14 to reduce the amount of air leakage in the assembly gap. Optionally, the elastic seal is provided on at least one side of the inner periphery of the slot 118. For example, for Figure 4c In the illustrated slot 118 form, the elastic seal may be disposed on any slot edge 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 may be a rubber strip, a wool strip, etc. Furthermore, the elastic sealing member may be fixedly connected to the inner periphery of the slot 118 by gluing, clamping, etc.

[0149] In some other optional embodiments, in order to make the air filter 14 move in / out of the air inlet chamber 11 more smoothly, the present application uses a slide assembly in the air inlet chamber 11 to limit the pulling trajectory of the air filter 14. The slide assembly can be used to limit the movement path of the air filter 14 relative to the air inlet chamber 11.

[0150] Optionally, the slide assembly includes a first track 171 and a second track 172, and the interval between the first track 171 and the second track 172 is configured as a pull-out space for the air filter element 14. Figure 3c and 4d As shown, the first track 171 is provided on the air outlet cavity wall 1116 and is extended and formed along the pulling direction. The first track 171 is located on the upper side of the air inlet cavity outlet 112, and is used to limit the position above the air filter element 14. The second track 172 is provided on the air outlet cavity wall 1116 and is extended and formed parallel to the first track 171. The second track 172 is located on the lower side of the air inlet cavity outlet 112, and is used to limit the position below the air filter element 14. The first track 171 and the second track 172 are arranged in parallel, and through the cooperation of the first track 171 and the second track 172, the air filter element 14 can be pulled and moved along the straight track defined by the two tracks.

[0151] Exemplary, combined Figure 4d As shown, the first track 171 is a first guide strip protruding from the air outlet cavity wall 1116 toward the outer cavity wall 1115, and the first guide 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. Similarly, the second track 172 is also a second guide strip protruding from the air outlet cavity wall 1116 toward the outer cavity wall 1115, and the second guide strip is also extended longitudinally from the third side wall 1113 to the fourth side wall 1114. After the air filter element 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 element 14 abuts against the lower surface of the first guide strip, and the bottom surface abuts against the upper surface of the second guide strip, which can reduce the occurrence of the problem of movement and dislocation of the air filter element 14.

[0152] In the above embodiments, the types of the air filter element 14 include, but are not limited to, a primary filter element, a high-efficiency filter element, an activated carbon filter element, etc. Those skilled in the art can select a suitable filter element type according to actual purification requirements, and this application does not limit this.

[0153] In some other optional embodiments, in order to further enhance the spatial separation effect of the air inlet chamber 11, a filter element separation bar 141 is provided inside the air filter element 14, and the filter element separation bar 141 separates the filter element into two filter element parts corresponding to two air inlet partitions (sub-air inlet chambers 11). Here, the filter element separation bar 141 can play a role in blocking the air from flowing between the two filter element parts, such as Figure 4a shown.

[0154] Here, the overall outer contour of the filter element partition strip 141 is in the form of a flat strip, which extends horizontally from the side of the air filter element 14 close to the partition plate 15 to the side close to the partition rib 16, and vertically extends from the top surface of the air filter element 14 to the bottom surface.

[0155] Combination Figure 4a As shown, the filter element partition bar 141 divides the air filter element 14 into a first filter element part 142 and a second filter element part 143. The first filter element part 142 is located on the side corresponding to the first sub-air inlet chamber 115, and can be used to filter and purify the air flowing through the first sub-air inlet chamber 115; the second filter element part 143 is located on the side corresponding to the second sub-air inlet chamber 116, and can be used to filter and purify the air flowing through the second sub-air inlet chamber 116. Due to the separation effect of the filter element partition bar 141, the air flowing through the first filter element part 142 will not flow to the second filter element part 143, and similarly, the air flowing through the second filter element part 143 will not flow to the first filter element part 142, thereby preventing the air of the two sub-air inlet chambers 11 from mixing in the air filter element 14.

[0156] Optionally, the filter element partition strip 141 is consistent with the linear shape of the partition plate 15, and the positions in the axial direction overlap. In this way, the air flow path jointly formed by the "partition plate 15-filter element partition strip 141-partition rib 16" will not form additional protrusions, the flow path is smooth and smooth, and the air flow resistance is effectively reduced. Exemplarily, if the extension line shape of the partition plate 15 is a straight line, the filter element partition strip 141 is also constructed as a straight strip; or, if the extension line shape of the partition plate 15 is an arc line, the filter element partition strip 141 is also constructed as an arc line strip. Here, the thickness of the partition plate 15, the filter element partition strip 141 and the partition rib 16 are basically the same to ensure the smoothness of the plane of the air flow path.

[0157] In some other optional embodiments, combined with Figures 5 to 5e As shown, the fan chamber 12 includes a fan volute 121 and an impeller 122. The impeller 122 is rotatably disposed inside the fan volute 121, and is used to rotate to generate a driving wind force to drive air to flow through the module housing 10. In this embodiment, the impeller 122 can at least drive air to flow from the air inlet chamber 11 to the fan chamber 12.

[0158] In an embodiment, the fan volute 121 is constructed as a detachable split structure, such as Figure 5c As shown, it includes a first volute portion 1211 and a second volute portion 1212. The detachable design can facilitate the installation / removal of the impeller 122 into / out of the fan volute 121, and is convenient for the assembly, replacement and maintenance of the fan volute 121. Here, the first volute portion 1211 is located on the side close to the air inlet chamber 11, and the second volute portion 1212 is located on the side of the air inlet chamber 11, and the two are assembled together to form the fan volute 121. Optionally, the first volute portion 1211 and the second volute portion 1212 can be fixed by means of snap connection, screw connection, riveting, etc., which has the advantages of firm connection and quick disassembly and assembly.

[0159] The fan volute 121 has a volute air inlet 123, which is used to communicate with the air inlet cavity outlet 112 of the air inlet cavity 11, so that air enters the fan volute 121 through the air inlet cavity outlet 112 and the volute air inlet 123 in sequence. In this embodiment, the volute air inlet 123 is provided on the first volute portion 1211, and the shape and size of the volute air inlet 123 are adapted to the air inlet cavity outlet 112. Exemplarily, the shape of the outlet of the air inlet cavity 11 is a circular air outlet, and accordingly, the volute air inlet 123 is also constructed in the form of a circular air outlet.

[0160] Optionally, the first volute portion 1211 and the air outlet cavity wall 1116 are an integrated structure, that is, the first volute portion 1211 and the air outlet cavity wall 1116 are two side surfaces of the same housing, the first volute portion 1211 is a side corresponding to the impeller 122, and the air outlet cavity wall 1116 is a side corresponding to the air filter element 14. In addition, the air inlet cavity outlet 112 of the air outlet cavity wall 1116 and the volute air inlet 123 of the first volute portion 1211 are also integrated into the same air outlet. In this way, the number of components of the module housing 10 can be reduced and the overall structure can be 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 constructed as an annular structure, and its internal space is used as an air inlet channel 1223 of the impeller 122, and the air inlet channel 1223 is formed by extending along the axial direction of the impeller 122. There are two hubs 1221, which are coaxially spaced, and the space between the two hubs 1221 is used as a space for accommodating a plurality of blades 1222. Here, each blade 1222 is constructed as a strip-shaped sheet structure, a first end of which is fixed to one of the hubs 1221, and the other end is fixedly connected to the other hub 1221. From the axial projection direction of the hub 1221, each blade 1222 is arranged at equal intervals along the outer circumference of the hub 1221, and is inclined relative to the outer circumference of the hub 1221, so that after the air enters the air inlet channel axially from the impeller 122, it is driven by the blades 1222 to diffuse radially outward and enter the shell space of the fan volute 121.

[0162] In the embodiment, the plurality of blades 1222 are evenly arranged along the outer circumference and together form an 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. In the axial direction from the air inlet cavity 11 to the fan cavity 12, the first rotation direction is that the airflow flows in a clockwise direction, and the second rotation direction is that the airflow flows in a counterclockwise direction.

[0164] In some of the optional embodiments described above, the fresh air module further includes an impeller driver 126 , which is drivingly connected to the impeller 122 and is used to drive the impeller 122 to rotate in the fan chamber 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 supply air to different directions, respectively, to achieve a multi-angle and wide range air supply effect.

[0166] Optionally, the first indoor air outlet 51 is used to supply air to one of the front, rear, top, bottom, left or right sides of the fresh air module 1, and the second indoor air outlet 52 is used to supply air to another of the front, rear, top, bottom, left or right sides of the fresh air module 1. Figure 5 and 5a In the illustrated embodiment, the first indoor air outlet 51 is used to supply air in a forward and upward direction, and the second indoor air outlet 52 is used to supply air in a downward and forward direction.

[0167] In some optional embodiments, the module housing 10 further includes a first air outlet duct 13, which is connected to the module housing 10 and is located at the air outlet side of the air inlet cavity 11 (fan cavity 12), and is used to construct a first indoor air outlet 51 as an air outlet path, and the air outlet airflow of the air inlet cavity 11 (fan cavity 12) can be transported to the external environment through the first air outlet duct 13. Similarly, the module housing 10 further includes a second air outlet duct, which is connected to the module housing 10 and is located at the air outlet side of the air inlet cavity 11 (fan cavity 12), and is used to construct a second indoor air outlet 52 as an air outlet path, and the air outlet airflow of the air inlet cavity 11 (fan cavity 12) can be transported to the external environment through the second air outlet duct.

[0168] In the above embodiment, the actual air supply direction can be adjusted by changing the extension direction of the first air outlet duct 13 (and the second air outlet duct) or the direction of the air outlet end of the duct. For example, in the above embodiment, the first indoor air outlet 51 is used to supply air to the front and upper direction, and the corresponding first air outlet duct 13 can be extended and formed in the front and upper direction, and its air outlet end faces the front and upper direction.

[0169] Here, the fan chamber 12 is arranged on the air outlet side of the air inlet chamber 11, and the first indoor air outlet 51 and the second indoor air outlet 52 are respectively connected to the fan chamber 12 through the fan chamber 12. In the embodiment, the first indoor air outlet 51 and the second indoor air outlet 52 are respectively connected to the outer peripheral shell wall of the fan volute 121, wherein the first indoor air outlet is connected to the top position of the outer peripheral shell wall, and the second indoor air outlet 52 is connected to the bottom position of the outer peripheral shell wall. When the impeller 122 rotates downward in the fan chamber 12, the air located upstream of the first indoor air outlet 51 will preferentially and concentratedly flow to the first indoor air outlet 51, as shown in FIG. Figure 7 and the air located upstream of the second indoor air outlet 52 will preferentially flow to the second indoor air outlet 52, such as Figure 7 The airflow is shown by the dashed arrows.

[0170] In some embodiments, in combination Figure 5b and 5c As shown, 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 of the outer peripheral shell wall of the fan volute 121, and is used to connect 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 via the first volute air outlet 124. The second volute air outlet 125 is provided at the bottom of the outer peripheral shell wall of the fan volute 121, and is used to connect 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 via the second volute air outlet 125.

[0171] exist Figure 7 The impeller 122 shown rotates downward for the first time, and the first indoor air outlet 51 is set corresponding to the first sub-air inlet chamber 115, and is located in the middle and downstream of the rotation direction of the impeller 122, that is, the airflow from the first sub-air inlet chamber 115 to the fan volute 121 is located in the middle and upstream of the first indoor air outlet 51, so that the airflow flowing through the first sub-air inlet chamber 115 will deviate to flow toward the first indoor air outlet 51, so that most of this part of the airflow is sent out through the first indoor air outlet 51. Similarly, the second indoor air outlet 52 is set corresponding to the second sub-air inlet chamber 116, and is located in the middle and downstream of the rotation direction of the impeller 122, that is, the airflow from the second sub-air inlet chamber 116 to the fan volute 121 is located in the middle and upstream of the second indoor air outlet 52, so that the airflow flowing through the second sub-air inlet chamber 116 will deviate to flow toward the second indoor air outlet 52, so that most of this part of the airflow is sent out through the second indoor air outlet 52.

[0172] In this embodiment, the first volute air outlet 124 includes a first extension section 1241 away from the volute axis and a first volute tongue section 1242 close to the volute axis. The first extension section 1241 and the first volute tongue section 1242 are arranged relatively spaced apart, and the space between the two is used as an airflow channel. Figure 5d Similarly, the second volute air outlet 125 includes a second extension section 1251 away from the volute axis and a second volute tongue section 1252 close to the volute axis. The second extension section 1251 and the second volute tongue end are arranged opposite to each other, and the space between the two serves as an airflow channel, as shown in FIG. Figure 5e Optionally, the range of the first sub-air inlet cavity 115 conveying airflow to the fan cavity 12 is mainly the covering part of the second volute tongue segment 1252 to the first volute tongue segment 1242 in the first downward rotation direction, as shown in FIG. Figure 8 The range of the second sub-air inlet chamber 116 conveying airflow to the fan chamber 12 is mainly the covering part of the first volute tongue segment 1242 to the second volute tongue segment 1252 in the first downward rotation, such as Figure 8 The B range area is shown in FIG.

[0173] In order to realize the division of the two air delivery coverage areas mentioned above, correspondingly, in the axial projection of the partition plate 15 relative to 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 section 1242, and the longitudinal second end (longitudinal bottom end) extends to the shell wall close to the second volute tongue section 1252, as shown in FIG. Figure 8 shown.

[0174] In this embodiment, the plate body of the partition plate 15 is longitudinally extended in a curve, and the direction of the curve corresponds to the air outlet direction of the first volute air outlet 124 and the second volute air outlet 125, thereby reducing the wind resistance of air flowing through the plate surface of the partition plate 15 and reducing wind pressure loss.

[0175] Combination Figure 3e As shown, the partition plate 15 includes 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 is formed by extending along the curvature of the first volute tongue segment 1242 of the fan volute 121 toward the axis of the fan volute 121. 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 is formed by extending along the curvature of the second volute tongue segment 1252 of the fan volute 121 toward the axial direction of the fan volute 121. The two ends of the middle arc plate segment 153 are respectively connected to the first arc plate segment 151 and the extending ends of the second arc plate segment toward the axis, that is, respectively connected to the lower end of the first arc plate segment 151 and the upper end of the second arc plate segment 152 .

[0176] In this embodiment, combined 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 smoother in the process of flowing through the air inlet cavity 11, the fan cavity 12 and finally being diverted to the first volute air outlet 124 and the second volute air outlet 125, thereby reducing the resistance effect of the cavity wall on the airflow flow.

[0177] Optionally, the extension curve of the first arc segment may be a curve trajectory with the same curvature as the first volute tongue segment 1242, or a curve trajectory with an acute angle to the curve of the first volute tongue segment 1242. Similarly, the extension curve of the second arc segment may be a curve trajectory with the same curvature as the second volute tongue segment 1252, or a curve trajectory with an acute angle to the curve of the second volute tongue segment 1252. In addition, the curve trajectories of the first arc plate segment 151 and the second arc plate segment 152 each have a tendency to bend and extend toward the axis of the fan volute 121, but do not necessarily point to the axis.

[0178] Optionally, the first arc plate segment 151 , the second arc plate segment 152 and the middle arc plate segment 153 adopt an integrated structure, so that there are no air leakage gaps between the plate segments of the partition plate 15 , thereby improving the sealing performance of the air inlet chamber 11 .

[0179] It should be understood that the extension direction of the partition plate 15 and the longitudinal end point settings in this embodiment are mainly set according to the opening positions of the two indoor air outlets, the rotation direction of the impeller 122 and other factors. For example, the two indoor air outlets in the embodiment are respectively located at the upper and lower sides of the fan chamber 12, so the partition plate 15 as a whole also extends vertically. When the arrangement position of the indoor air outlet changes, such as changing to front and rear side air outlets, the extension direction of the partition plate 15 must also be adaptively adjusted. Therefore, other deformation adjustment schemes for the opening position of the indoor air outlet and the form of the partition plate 15 by those skilled in the art based on the technical concept disclosed in this application and combined with the actual air supply needs should also be covered within the protection scope of this application.

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

[0181] Among them, the first partition is arranged in the air inlet channel 1223, which is used to divide the air inlet channel 1223 into a first air inlet area and a second air inlet area. The airflow in the first air inlet area flows toward the first volute air outlet 124, and the airflow in the second air inlet area flows toward the second volute air outlet 125.

[0182] In the present embodiment, a partition component is provided in the air inlet channel 1223 of the impeller 122 of the fan chamber 12. The partition component can play a role in spatially dividing the air inlet channel 1223, thereby dividing the air inlet channel 1223 into two air inlet areas. The mixing of air flows between the two air inlet areas can be effectively reduced, so that the air in each part of the two air inlet areas can be more inclined to be discharged from the corresponding air outlet, thereby enhancing the diversion air supply effect of the fresh air module 1.

[0183] Optionally, the first partition includes a first partition 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 partition plate are spaced 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 partition plate and the inner edges of the blades 1222 be reduced, and the air flow mixing between the first air inlet area and the second air inlet area can be reduced, but also the first partition plate and the impeller 122 can be prevented from interfering with each other, resulting in the first partition plate and the blades 1222 colliding with each other, deforming and damaging.

[0184] In the embodiment, the air inlet channel 1223 is formed by extending along the axial direction of the impeller 122, so the air entering the air inlet channel 1223 is also vortex-divided to the air outlet side by the blades 1222 in the entire axial direction. Accordingly, the plate body of the first partition plate is formed by extending transversely from the air inlet side of the air inlet channel 1223 along the axial direction of the impeller 122, so as to cover the axial extension range of the air inlet channel 1223, thereby improving the partitioning effect of the internal space of the air inlet channel 1223.

[0185] Optionally, the first partition plate is a linear plate or a non-linear plate. Further, the non-linear plate includes a curved shape, a broken line shape, or a plate body formed by splicing multiple sections of one or more linear shapes and / or one or more curved shapes.

[0186] In some embodiments, the second partition is disposed in the air inlet chamber 11, and can divide the air inlet chamber 11 into a first sub-air inlet chamber 115 and a second sub-air inlet chamber 116. Furthermore, the first sub-air inlet chamber 115 corresponds to the first air inlet area, so that the airflow of the first sub-air inlet chamber 115 flows to the first air inlet area, and the second sub-air inlet chamber 116 corresponds to the second air inlet area, so that the airflow of the second sub-air inlet chamber 116 flows to the second air inlet area. In this way, through the cooperation of the second partition and the first partition, the airflow paths of the fresh air flow and the polluted air flow are kept separated during the process of flowing through the air inlet chamber and the fan chamber, thereby improving the diversion air supply effect.

[0187] In this embodiment, the second partition includes a second partition plate, the plate body of which is longitudinally extended from one side wall of the air inlet cavity 11 to the other side wall. Figures 3a to 3e The separator plate in the embodiment shown.

[0188] Alternatively, the second partition plate is consistent with the extension track of the first partition plate to ensure the consistency and smoothness of the partition surface formed by the second partition plate and the first partition plate from the air inlet chamber 11 to the fan chamber 12. Here, the extension length of the second partition plate and the first partition plate is the same or different. For example, when the cavity space of the air inlet chamber 11 is larger than the diameter of the air inlet channel 1223, the extension length 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 extension track of part of the second partition plate.

[0189] In some embodiments, the second partition plate and the first partition plate are an integrally formed structure, which can effectively ensure the stability of the connection between the two partition plates and no additional air leakage gap is formed between the two.

[0190] In some embodiments, the fresh air module further includes an air outlet group, and the air outlet group includes a first air outlet and a second air outlet. Here, the air outlet group is opened in the fan chamber 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 downward rotation of the fan chamber, the airflow in the first air inlet area flows toward the first air outlet, and the airflow in the second air inlet area flows toward the second air outlet. Optionally, the first air outlet is the first volute air outlet 124 in the previous embodiment, and the second air outlet is the second volute air outlet 125.

[0191] 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. Accordingly, the first partition plate is formed with an avoidance groove for avoiding the impeller driver 126, thereby preventing the first partition plate from interfering with the impeller driver 126 during rotation.

[0192] Here, the avoidance groove and the impeller driver 126 are spaced apart, and under the premise of avoiding contact, the gap between the groove edge and the impeller driver 126 is minimized to improve the airtight effect and reduce the mixing of airflows in the two air inlet areas in the air inlet channel 1223 through the gap.

[0193] In some optional embodiments, combined with Fig. 9 As shown, the module housing 10 has an outdoor air outlet 114 connecting the air inlet chamber 11 and the outdoor side. Specifically, the outdoor air outlet 114 is connected to at least one of the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116, so that the outdoor fresh air in the outdoor environment can be introduced into at least one of the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116.

[0194] Here, the number of sub-air inlet chambers 11 connected to the outdoor air outlet 114 is dynamically adjusted according to the working state of the fresh air module 1. For example, in the fresh air mode, the outdoor air outlet 114 is connected to the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116 at the same time. In the two-way air exchange mode, the outdoor air outlet 114 is only connected to one of the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116, and the other is not connected.

[0195] Optionally, the outdoor air vent 114 is provided 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 switchable and adjustable with various connection forms. For example, the outdoor air vent 114 can be provided on the outer cavity wall 1115, the first side wall 1111 or the second side wall 1112. Here, the outer cavity wall 1115, the first side wall 1111 or the second side wall 1112 have in common that at least part of the wall surface of each side wall is located on the side adjacent to the first sub-air inlet cavity 115, and at least another part of the wall surface is located on the side adjacent to the second sub-air inlet cavity 116. Exemplarily, in combination with Fig. 9 As shown, the outdoor air inlet is opened on the second side wall 1112 of the air inlet chamber 11, and is located on a side close to the first sub-air inlet chamber 115. In this embodiment, the fresh air mode is in the two-way air exchange mode, and the outdoor air inlet 114 is connected to the first sub-air inlet chamber 115, and is not connected to the second sub-air inlet chamber 116.

[0196] Optionally, the shape of the outdoor air outlet 114 is constructed in a circular, rectangular, square or other form, which is not limited in the present application.

[0197] In some alternative embodiments, combined with Fig.10 As shown, the module housing 10 has an indoor return air port 113 connecting the air inlet chamber 11 and the indoor side. Specifically, the indoor return air port 113 is connected to at least one of the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116, so that the indoor polluted air in the indoor side environment can be introduced into at least one of the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116.

[0198] Here, the number of sub-air inlet chambers 11 connected to the indoor return air outlet 113 is dynamically adjusted according to the working state of the fresh air module 1. For example, in the two-way air exchange mode, the indoor return air outlet 113 is only connected to one of the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116, and the other is not connected; in the full return air mode, the indoor return air outlet 113 is connected to the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116 at the same time.

[0199] Optionally, the indoor return air vent 113 is provided 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 switchable and adjustable with various connection forms. For example, the indoor return air vent 113 can be provided 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 at least part of the wall surface of each side wall is located on the side adjacent to the first sub-air inlet cavity 115, and at least another part of the wall surface is located on the side adjacent to the second sub-air inlet cavity 116. Exemplarily, in combination with Fig.11 As shown, the indoor return air vent 113 is opened on the second side wall 1112 of the air inlet chamber 11 and is located on a side close to the second sub-air inlet chamber 116. In this embodiment, the fresh air mode is in the two-way air exchange mode, and the indoor return air vent 113 is connected to the second sub-air inlet chamber 116 and is not connected to the first sub-air inlet chamber 115.

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

[0201] In some optional embodiments, the fresh air module 1 further includes a return air switch unit, which is arranged at the indoor return air outlet 113, and the return air switch unit is used to controllably close or open the indoor return air outlet 113. Optionally, the return air switch unit is configured to at least close the indoor return air outlet 113 in the fresh air mode, so that the indoor polluted air on the indoor side will not be introduced into the air inlet chamber 11 in the fresh air mode; and open the indoor return air outlet 113 in the two-way air exchange mode, so that the indoor polluted air on the indoor side flows into the air inlet chamber 11 through the indoor return air outlet 113 under the drive of the negative pressure wind force of the impeller 122.

[0202] Here, the return air switch unit includes a return air damper and a first driver. The return air damper is drivingly connected to the first driver, so that the return air damper is driven to close or open the indoor return air port 113.

[0203] Optionally, the return air baffle is slidably disposed at the indoor return air outlet 113 relative to the second side wall 1112, and a first rack is disposed on one side of the return air baffle, and the first rack is formed along the longitudinal extension of the side; the first driver includes a first drive motor and a first gear, and the first gear is sleeved on the drive shaft of the first drive motor and meshed with the first rack. In this way, by controlling the first drive motor to rotate in both directions, the return air baffle is driven by the cooperation of the first gear and the first rack to move toward the direction close to the indoor return air outlet 113 or away from the indoor return air outlet 113. When moving toward the direction close to the indoor return air outlet 113, the return air baffle can cover the indoor return air outlet 113 to close the indoor return air outlet 113; and when moving toward the direction away from the indoor return air outlet 113, the return air baffle is separated from the position of covering the indoor return air outlet 113 to open the indoor return air outlet 113.

[0204] Alternatively, the return air baffle can be pivotally connected to a side edge of the indoor return air outlet 113, and the first driver includes a first drive motor and a pivot shaft, and the return air baffle is arranged on the pivot shaft. In this way, by controlling the first drive motor to drive the return air baffle to flip, the return air baffle can close or open the indoor return air outlet 113.

[0205] In an optional embodiment, the outdoor air vent 114 and the indoor return air vent 113 are both disposed on the second side wall 1112 of the air inlet chamber 11 and are respectively located on both sides of the partition plate 15, wherein the outdoor air vent 114 is located on the side of the partition plate 15 corresponding to the first sub-air inlet chamber 115, and the indoor return air vent 113 is located on the side of the partition plate 15 corresponding to the second sub-air inlet chamber 116. Fig.11 shown.

[0206] In some other optional embodiments, combined with Fig.12 As shown, the fresh air duct 20 includes an air duct body 21 and a pipe joint 22. The air duct body 21 extends from the indoor side to the outdoor side, and the pipe joint 22 is arranged on the indoor side end of the air duct body 21, which is used to connect the air duct body 21 and the module housing 10. In this embodiment, the pipe joint 22 is used to connect the air duct body 21 and the outdoor air outlet 114 and the air outlet switching part 30.

[0207] In an embodiment, the fresh air duct 20 has a first air duct channel 231 and a second air duct channel 232 which are separated from each other and are used to connect the outdoor air outlet 114 and the outdoor side. The outdoor fresh air can be introduced from the outdoor side to the outdoor air outlet 114 of the module housing 10 by the first air duct channel 231 and the second air duct channel 232 respectively.

[0208] Exemplary, combined Fig.13As shown, a duct partition 213 is provided inside the duct body 21, and the duct partition 213 is formed by extending longitudinally along the duct body 21, and divides the duct body 21 into two relatively independent duct body 21 channels, including a first duct body channel 211 and a second duct body channel 212. Similarly, a joint partition 223 is also provided inside the pipe joint 22, and the joint partition 223 is formed by extending along the pipeline direction of the pipe joint 22, specifically extending from one end of the pipe joint 22 connected to the duct body 21 to one end connected to the outdoor air outlet 114, and divides the pipe joint 22 into two relatively independent joint channels, including a first joint channel 221 and a second joint channel 222. At the same time, the joint partition 223 corresponds to the position of the duct partition 213, so that the first duct body channel 211 and the first joint channel 221 together constitute the first duct channel 231, and the second duct body channel 212 and the second joint channel 222 together constitute the second duct channel 232. Optionally, the outdoor air outlet 114 of the module housing 10 is also provided with a partition, which can be used to divide the outdoor air outlet 114 into independent air inlet paths corresponding to the two joint channels of the pipe joint 22.

[0209] Optionally, the duct partition plate 213 divides the duct body 21 into two duct body 21 channels with the same channel cross-sectional area. For example, if the duct body 21 has a circular cross-sectional area, the duct partition plate 213 is formed by extending along a radial line of the duct body 21 in the cross-sectional view. Fig.13a As shown. In this embodiment, the two air duct bodies 21 can achieve an air supply effect of equal air volume delivery. For example, in the two-way air exchange mode, the two air duct bodies 21 can deliver outdoor fresh air and indoor polluted air respectively, and the outdoor fresh air intake volume is substantially the same as the indoor polluted air exhaust volume, thereby ensuring the stability of the indoor air pressure during the operation of the fresh air module 1.

[0210] Alternatively, the duct baffle 213 divides the duct body 21 into two duct body 21 channels with different channel cross-sectional areas. For example, if the duct body 21 has a circular cross-sectional area, the duct baffle 213 is formed by extending in a straight line direction at an angle to the radial line of the duct body 21 in the cross-sectional view. Fig.13b As shown. Alternatively, the air duct partition 213 is a non-linear partition, such as an arc-shaped plate, a folded-line plate, etc., which can also achieve unequal division of the air duct body 21 space. In this way, in this embodiment, the two air duct body 21 channels can achieve an air supply effect of unequal air volume delivery. For example, in the two-way air exchange mode, the cross-sectional area of ​​the first air duct body channel 211 is larger than the cross-sectional area of ​​the second air duct body channel 212, so that the outdoor fresh air intake volume corresponding to the first air duct body channel 211 is larger than the indoor dirty air exhaust volume corresponding to the second air duct body channel 212, so that a positive pressure air supply effect can be achieved for the indoor environment.

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

[0213] Furthermore, the branch pipe opening 2322 is connected between the indoor air outlet and the air outlet side of the air inlet chamber 11, and can be used to direct at least part of the air output from the air outlet side of the air inlet chamber 11 to flow to the second air duct channel 232 via the branch pipe opening 2322, and then discharge the part of the air to the outdoor side. In combination with the previous embodiment, the fan chamber 12 is located on the air outlet side of the air inlet chamber 11, and the branch pipe opening 2322 is connected between the volute air outlet of the fan chamber 12 and the indoor air outlet of the module housing 10, so that the air output from the volute air outlet can flow to one or both of the indoor air outlet and the branch pipe opening 2322. Fig.15 As shown, the branch pipe opening 2322 is arranged adjacent to the lower portion of the module housing 10 , and thus in order to save the length of the pipeline consumables, the branch pipe opening 2322 is connected between the second volute air outlet 125 of the fan chamber 12 and the second indoor air outlet 52 of the module housing 10 .

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

[0215] In some optional embodiments, the fresh air module 1 further includes an air duct switch unit, which is disposed at the position of the second fresh air outlet 2321, and the air duct switch unit is used to controllably open or close the second fresh air outlet 2321. Optionally, the air duct switch unit is configured to at least open the second fresh air outlet 2321 in the fresh air mode, so that the second air duct channel 232 is connected to the outdoor air outlet 114, and the outdoor fresh air can flow into the air inlet cavity 11; and close the second fresh air outlet 2321 in the two-way air exchange mode, so that the second air duct channel 232 is blocked from the outdoor air outlet 114.

[0216] Here, the air duct switch unit includes an air duct baffle and a second driver, and the air duct baffle is drivingly connected to the second driver, so that the air duct baffle is driven to close or open the second fresh air outlet 2321.

[0217] Optionally, the duct baffle is slidably disposed at the second fresh air outlet 2321 relative to the second side wall 1112, a second rack is disposed on one side of the duct baffle, and the second rack is formed along the longitudinal extension of the side; the second driver includes a second drive motor and a second gear, and the second gear is sleeved on the drive shaft of the second drive motor and meshed with the second rack. In this way, by controlling the second drive motor to rotate in both directions, the duct baffle is driven by the cooperation of the second gear and the second rack to move toward the second fresh air outlet 2321 or away from the second fresh air outlet 2321. When moving toward the second fresh air outlet pipe opening 2321, the air duct baffle can cover the indoor return air outlet 113 to close the second fresh air outlet pipe opening 2321; and when moving toward the direction away from the second fresh air outlet pipe opening 2321, the air duct baffle moves away from the position covering the second fresh air outlet pipe opening 2321 to open the second fresh air outlet pipe opening 2321.

[0218] Alternatively, the duct baffle can be pivotally connected to a side edge of the second fresh air outlet 2321, and the second driver includes a second drive motor and a pivot shaft, and the duct baffle is disposed on the pivot shaft. In this way, the duct baffle can be controlled to flip the second drive motor to close or open the second fresh air outlet 2321.

[0219] In the previous article Fig.11 In the illustrated embodiment, since the outdoor air outlet 114 (the second fresh air outlet pipe opening) and the indoor return air outlet 113 are both arranged on the second side wall 1112 of the air inlet chamber 11, and the two are arranged adjacent to each other, in this embodiment, the outdoor air outlet 114 (the second fresh air outlet pipe opening) and the indoor return air outlet 113 can share the same switch component, and the same switch component can be used to simultaneously realize the switching of the closed / open state of the second fresh air outlet pipe opening and the indoor return air outlet 113, which can effectively simplify the number of switch components and the complexity of the module structure.

[0220] Specifically, combined Fig.16 and 16a As shown, the fresh air module 1 also includes an integrated switch unit 40, which is arranged on the second side wall 1112 where the outdoor air outlet 114 and the indoor return air outlet 113 are located, and is configured to at least open the second fresh air outlet pipe port 2321 and close the indoor return air outlet 113 in the fresh air mode; and close the second fresh air outlet pipe port 2321 and open the indoor return air outlet 113 in the two-way air exchange mode.

[0221] Combination Fig.16As shown, the integrated switch unit 40 includes a windshield 41 and an integrated driver. The windshield 41 is slidably disposed on the second side wall 1112 of the air inlet chamber 11. The integrated driver is drivingly connected to the windshield 41, and is configured to at least drive the windshield 41 to move between a first sliding position and a second sliding position; when the windshield 41 is in the first sliding position, the windshield 41 opens the first fresh air outlet 2311 and the second fresh air outlet 2321, and blocks the indoor return air outlet 113, as shown in FIG. Fig.17a and the windshield 41 is in the second sliding position, the windshield 41 blocks the second fresh air outlet 2321, and open the indoor return air outlet 113 and the first fresh air outlet 2311, as Fig.17b Here, the first sliding position is located at a position of the second side wall 1112 close to the second sub-air inlet chamber 116 , and the second sliding position is located at a position of the second side wall 1112 close to the first sub-air inlet chamber 115 .

[0222] Optionally, a baffle rack 42 is provided on one side (or side) of the windshield 41, and the baffle rack 42 is formed along the longitudinal extension of the side. The integrated driver includes an integrated drive motor 43 and an integrated gear 44, and the integrated gear 44 is sleeved on the drive shaft of the integrated drive motor 43 and meshed with the baffle rack 42. In this way, by controlling the integrated drive motor 43 to rotate in both directions, the windshield 41 is driven by the cooperation of the integrated gear 44 and the baffle rack 42 to move to the first sliding position or the second sliding position.

[0223] In some other optional embodiments, the integrated drive is further configured to move closer to or away from the third sliding position. Here, when the wind shield 41 is in the third sliding position, the wind shield 41 completely blocks the outdoor air outlet 114, so that the first air duct channel 231 and the second air duct channel 232 are both in a blocked state with the air inlet cavity 11, and the indoor return air outlet 113 is in an open state. Fig.17c shown.

[0224] exist Fig.17c When the wind shield 41 is at the third sliding position, outdoor fresh air cannot be introduced into the air inlet cavity 11, and indoor air is only delivered to the air inlet cavity 11 through the indoor return air port 113.

[0225] In some optional embodiments, the partition plate 15 is a split structure, which includes a first partition plate 154 and a second partition plate 155 connected along the longitudinal direction of the plate body.

The second partition 155 is arranged on the wind shield 41 of the integrated switch unit 40, and the second partition 155 can slide synchronously with the wind shield 41. In this embodiment, the bottom end of the second partition 155 is fixed to the side surface of the wind shield 41 facing the air inlet cavity 11. Optionally, the second partition 155 and the wind shield 41 are an integrated structure, or the bottom end of the second partition 155 is fixed to the corresponding side surface of the wind shield 41 by gluing, welding, etc.

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

[0228] Furthermore, when the wind shield 41 moves to the third sliding position, the first partition 154 and the second partition 155 are staggered, and the second partition 155 moves to the cavity space of the first sub-air inlet chamber 115, so that the area originally separated and blocked by the second partition 155 is opened, so that the indoor return air outlet 113 is connected with the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116, and the indoor air can flow to the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116 at the same time.

[0229] In some other optional embodiments, combined with Figures 18 to 18b As shown in Figure 22, the fresh air module 1 also includes an air outlet switching part 30 (air outlet switching mechanism), which is arranged at the connecting position of the branch pipe opening 2322, the second indoor air outlet 52 and the air outlet side of the air inlet chamber 11. The air outlet switching part 30 can be used for controlled switching so that the air outlet side of the air inlet chamber 11 is connected to one of the branch pipe opening 2322 and the second indoor air outlet 52, and the other is blocked.

[0230] In combination with the above embodiments, the fan cavity 12 is located at the air outlet side of the air inlet cavity 11, and the second indoor air outlet 52 is connected to the fan cavity 12. In this embodiment, the air outlet switching unit 30 is configured to be switchable at least between a fresh air state and a two-way air exchange state; wherein in the fresh air state, the air path of the fan cavity 12 and the second indoor air outlet 52 is connected, and the air path of the branch pipe port 2322 is blocked; in the two-way air exchange state, the air path of the fan cavity 12 and the branch pipe port 2322 is connected, and the air path of the second indoor air outlet 52 is blocked.

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

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

[0233] Optionally, the wind blocking assembly includes a wind blocking block 32 and a wind blocking motor 33, such as Fig.19 As shown. The wind blocking block 32 is rotatably disposed in the switching air cavity; the wind blocking motor 33 is drivingly connected to the wind blocking block 32, and is configured to at least drive the wind blocking block 32 to move between a first rotation position and a second rotation position. The first rotation position corresponds to the fresh air state. When the wind blocking block 32 is in the first rotation position, it blocks the first switching air outlet 312 (branch pipe opening 2322), so that the switching air inlet 311 is only connected to the second switching air inlet 311 (second indoor air outlet 52). Fig.20a The second rotation position corresponds to the two-way air exchange state. When the wind blocking block 32 is in the second rotation position, it blocks the second switching air outlet 313 (the second indoor air outlet 52), so that the switching air inlet 311 is only connected to the first switching air inlet 311 (branch pipe port 2322). Fig.20b shown.

[0234] In some optional embodiments, the switch air inlet 311, the first switch air outlet 312 and the second switch air outlet 313 are arranged at intervals in the switch housing 31 along the circumferential direction of the rotation axis of the air blocking block 32. Fig.20a and 20bAs shown, the switch air inlet 311 is located at the upper side of the rotation axis, the first switch air outlet 312 is located at the right side of the rotation axis, and the second switch air outlet 313 is located at the lower left side of the rotation axis. In this way, the air blocking block 32 can switch between multiple set rotation positions during the process of rotating around the outer circumference of its rotation axis.

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

[0236] Combination Fig.18a and 21a As shown, the wind blocking block 32 includes a central rotating shaft 321 and a wind blocking baffle 322. The central rotating shaft 321 is coaxially arranged at the center of the circular cavity 314 and is drivingly connected to the wind blocking motor 33, which is arranged at an axial outer side of the switching housing 31. The wind blocking baffle 322 is fixedly connected to the central rotating shaft 321, so that the wind blocking motor 33 can drive the wind blocking baffle 322 to rotate in the circular cavity 314 through the central rotating shaft 321.

[0237] Optionally, the wind blocking baffle 322 includes an arc plate 3221 and a support plate 3222. The arc plate 3221 is formed by extending along the circumference of the circular cavity 314, and the arc of the arc plate 3221 is greater than or equal to the arc of each arc opening, so that any arc opening can be blocked during the rotation process. The support plate 3222 is used to connect the central shaft 321 and the wind blocking baffle 322, and is constructed as a fan-shaped sheet body whose plate surface extends radially from the central shaft 321, the arc edge of the support plate 3222 is fixedly connected to the wind blocking baffle 322, and the arc center is fixedly connected to the central shaft 321, such as Fig.19a shown.

[0238] In some optional embodiments, the number of support plates 3222 is one, which is fixed to one end of the central shaft 321, such as the left end or the right end of the central shaft 321. A single support plate 3222 can effectively reduce the overall weight of the wind blocking baffle 322, thereby reducing the operating power consumption of the wind blocking motor 33. In some other optional embodiments, the number of support plates 3222 is two, and the two are symmetrically fixed to the two ends of the central shaft 321. In this embodiment, the two support plates 3222 can provide support for the axial sides of the arc-shaped plate 3221, prevent the wind blocking baffle 322 from being deflected under the force of wind pressure, and ensure the wind blocking effect of the wind blocking baffle 322 in the switching wind cavity.

[0239] Optionally, the motor housing of the wind blocking motor 33 is provided with a fixing ear plate 331, and the fixing ear plate 331 is provided with a screw hole, such as Fig.19bThe outer wall of the circular cavity 314 is provided with a fixing seat 315, as shown Fig.21 The wind blocking motor 33 is assembled in the circular cavity 314 through the fixing ear plate 331 and the fixing seat 315 .

[0240] In some other optional embodiments, the second air duct channel 232 can be replaced by another separate sewage exhaust air duct, that is, the first air duct channel 231 is used as a fresh air duct 20 alone, which is used to transport outdoor fresh air to the indoor side; the sewage exhaust air duct replaces the second air duct channel 232, which can at least be used to discharge indoor sewage air to the outdoor side. Here, the sewage exhaust air duct has an indoor pipe port on the indoor side and an outdoor pipe port on the outdoor side, wherein the indoor pipe port is connected to the first switching outlet of the air outlet switching mechanism. After the indoor sewage air enters the module housing 10 from the indoor return air port 113, it flows to the sewage exhaust air duct after passing through the air inlet chamber 11, the fan chamber 12, and the switching air chamber in sequence, and is finally discharged to the outdoor side through the sewage exhaust air duct.

[0241] In the embodiment, the sewage exhaust duct and the indoor air outlet are arranged at a certain distance. Fig.18a As shown, the switch air cavity further includes an outer expansion cavity, which extends from the circular cavity 314 to one side of the sewage exhaust air duct (the second air duct passage 232) to connect the circular cavity 314 and the indoor pipe opening (branch pipe opening 2322) of the sewage exhaust air duct (the second air duct passage 232). The extension distance of the outer expansion cavity is adapted to the spacing distance of the sewage exhaust air duct relative to the indoor air outlet.

[0242] The partition plate 15 shown in the above embodiment is fixed in the internal space of the air inlet chamber 11, and the relative position of the partition plate 15 and the air inlet chamber 11 is immutable, which makes the cavity space of the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116 basically fixed. This limits the application scope of the fresh air module and cannot meet certain functional enhancement requirements of users. For example, when the air quality difference between the indoor and outdoor environments is not large, but the temperature difference is large, some users may want to appropriately reduce the outdoor fresh air input to reduce the disturbance effect of the outdoor fresh air on the indoor temperature. In view of the above situation, in some optional embodiments, the partition component provided in the fresh air module 1 is designed in a movable form, so that the partition component can move relative to the inner cavity of the module housing 10, and during the movement, the cavity space of the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116 is changed, thereby achieving the effect of changing the outdoor fresh air volume delivered by the first sub-air inlet chamber 115 and / or the indoor polluted air volume delivered by the second sub-air inlet chamber 116.

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

[0244] Optionally, the partition component can adjust its relative position to the air inlet cavity 11 by rotating, sliding, etc. relative to the air inlet cavity 11.

[0245] Here, the air inlet cavity outlet 112 is provided on the air outlet cavity wall 1116, and the partition component can separate the air inlet cavity outlet 112 into a first sub-outlet and a second sub-outlet, and the first sub-outlet and the second sub-outlet correspond to the first sub-inlet cavity 115 and the second sub-inlet cavity 116, respectively, so as to serve as the paths for the airflows of the two sub-inlet cavities to be output to the fan cavity 12. In this way, during the operation of the partition component rotating, sliding, etc. relative to the air inlet cavity 11, the relative position of the partition component and the air inlet cavity outlet 112 can be changed, so that the position of the separation boundary of the partition component for the first sub-outlet and the second sub-outlet is changed, thereby achieving the effect of changing the outdoor fresh air volume of the first sub-inlet cavity 115 and / or the indoor polluted air volume of the second sub-inlet cavity 116.

[0246] Specifically, in some optional embodiments, combined with Figures 22a to 22c As shown, the partition component is pivotally connected to the air inlet chamber 11, so that the partition component can rotate relative to the air inlet chamber 11, thereby achieving the purpose of adjusting its relative position with the air inlet chamber 11. In this embodiment, the partition component includes a movable partition 181 and a partition driver 182, and the partition driver 182 can drive the movable partition 181 to rotate in the air inlet chamber 11.

[0247] Here, the movable partition 181 is pivoted in the air inlet cavity 11, and its rotation plane is parallel to the wall surface of the air outlet cavity wall 1116. Optionally, the movable partition 181 is pivoted to another cavity wall of the air inlet cavity 11 relative to the air outlet cavity wall 1116, that is, the outer cavity wall 115 in the above embodiment, and the outer cavity wall is provided with a through hole for the motor shaft to penetrate. The partition driver 182 includes a partition driving motor and a motor shaft, such as Fig.22d As shown, the partition drive motor is fixed on the outer wall surface of the outer cavity wall, and its motor shaft extends into the air inlet cavity 11 through the above-mentioned through hole, and is fixedly connected to the movable partition 181, so that the partition drive motor can drive the movable partition 181 to rotate by rotating the motor.

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

[0249] In this embodiment, similar to the partition plates shown in the previous embodiments, the movable partition plate 181 and at least a portion of the cavity wall of the air inlet cavity 11 are surrounded to form a first sub-air inlet cavity 115, and are surrounded to form a second sub-air inlet cavity 116 with at least another portion of the cavity wall of the air inlet cavity 11. In this way, when the movable partition plate 181 rotates around the axial direction in the air inlet cavity 11, the cavity space of the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116 surrounded by it can be changed.

[0250] In an optional embodiment, the two longitudinal ends of the movable partition 181 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 this embodiment. Here, the two longitudinal ends of the movable partition 181 are defined as the first outer plate end and the second outer plate end. Also, the two lateral sides of the movable partition 181 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 this embodiment. Here, the two longitudinal ends and the two lateral sides of the movable partition 181 are spaced from the corresponding side walls to leave a gap for rotation, so as to avoid the side walls of the air inlet cavity 11 from hindering the rotation of the movable partition 181.

[0251] In combination with the above-mentioned embodiment, an outdoor air outlet 114 and an indoor return air outlet 113 are provided on the second side wall 1112 at intervals, wherein the outdoor air outlet 114 is used to deliver outdoor fresh air to the first sub-air inlet chamber 115, and the indoor return air outlet 113 is used to deliver indoor polluted air to the second sub-air inlet chamber 116. Optionally, the rotation range of the movable partition plate 181 is limited to that one longitudinal end portion thereof corresponding to the second side wall 1112 is always located between the outdoor air outlet 114 and the indoor return air outlet 113, so that the outdoor air outlet 114 always corresponds to the first sub-air inlet chamber 115, and the indoor return air outlet 113 always corresponds to the second sub-air inlet chamber 116.

[0252] Optionally, the air inlet chamber 11 is constructed as a cavity having a circular or approximately circular outer contour, and the rotation axis of the movable baffle 181 is arranged at the center of the air inlet chamber 11. In this way, the longitudinal ends of the movable baffle 181 extend to the inner circumference of the air inlet chamber 11 respectively, and can be driven by the baffle driver 182 to rotate along the circumferential direction of the air inlet chamber 11.

[0253] Alternatively, the movable partition plate 181 is a linear plate or a non-linear plate. Optionally, the non-linear plate includes a curved shape, a folded line shape, or a plate body formed by splicing multiple sections of one or more linear shapes and / or one or more curved shapes.

[0254] In some further optional embodiments, the partition component further includes one or more static partitions, which can cooperate with the dynamic partition 181 to jointly define the rotation area where each sub-air inlet chamber and / or the dynamic partition 181 is located.

[0255] Specifically, combined Fig.22c As shown, the partition member includes a first static partition plate 183 and / or a second static partition plate 184. Optionally, the first static partition plate 183 is arranged on the side wall of the air inlet cavity 11 where the outdoor air outlet 114 and the indoor return air outlet 113 are located. Fig.22c The second side wall 1112 in the air inlet cavity 11 is formed and extends toward the inner side of the air inlet cavity 11; the first static baffle 183 can play the role of separating the outdoor air outlet 114 and the indoor return air outlet 113, so as to limit the outdoor air outlet 114 to the space range of the first sub-air inlet cavity 115 and the indoor return air outlet 113 to the space range of the second sub-air inlet cavity 116. Alternatively, the second static baffle 184 is arranged on the other side wall opposite to the side wall where the first static baffle 183 is located, such as Fig.22c The first side wall 1111 in the middle is also extended toward the inner side of the wall of the air inlet chamber 11; the second static partition plate 184 can play the role of separating the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116.

[0256] In this embodiment, the first static partition plate 183 and the second static partition plate 184 are spaced apart, and the rotation area of ​​the dynamic partition plate 181 is located in the spaced apart space.

[0257] In this way, one side of the moving baffle 181, one side of the first static baffle 183, one side of the second static baffle 184 and at least a part of the cavity wall of the air inlet cavity 11 are jointly enclosed to form a first sub-air inlet cavity 115; here, at least a part of the cavity wall of the air inlet cavity 11 may include an outer cavity wall 1115, an air outlet cavity wall 1116, a first side wall 1111, a second side wall 1112 and a fourth side wall 1114. And, the other side of the moving baffle 181, the other side of the first static baffle 183, the other side of the second static baffle 184 and at least another part of the cavity wall of the air inlet cavity 11 are jointly enclosed to form a second sub-air inlet cavity 116; here, at least a part of the cavity wall of the air inlet cavity 11 may include an outer cavity wall, an air outlet cavity wall 1116, a first side wall 1111, a second side wall 1112 and a third side wall 1113.

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

[0259] Similar, combined Fig.22c As shown, the second static partition 184 includes a second straight plate segment 1841 and a second arc segment 1842. Among them, one longitudinal end of the first straight plate segment 1831 is fixedly connected to the first side wall 1111, and the other end extends toward the inner side of the air inlet cavity 11; one end of the second arc segment 1842 is fixedly connected to the extended end of the second straight plate segment 1841, and the other end is a free end. The second arc segment 1842 is integrally extended and formed along the rotational outer circumference of the second outer plate end of the moving partition 181, and the second outer plate end of the moving partition 181 can be slidably abutted against the inner plate surface of the second arc segment 1842. Alternatively, the end of the second arc segment 1842 connected to the second straight plate segment 1841 can continue to extend along the rotational outer circumference to expand the rotation range of the second outer plate end.

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

[0261] In this embodiment, the rotation range of the movable partition plate 181 is limited to the angle range corresponding to the shortest arc segment of the first arc segment 1832 and the second arc segment 1842. In this way, it can be ensured that the first outer plate end of the movable partition plate 181 can always abut against the first arc segment 1832, and the second outer plate end can always abut against the second arc segment 1842 during the rotation process.

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

[0265] Optionally, the air outlet group is provided in the fan chamber 12 of the fresh air module, and the first air outlet corresponds to the first sub-air inlet chamber 115, and the second air outlet corresponds to the second sub-air inlet chamber 116. When the fan chamber rotates downward, at least part of the airflow of the first sub-air inlet chamber 115 flows toward the first air outlet, and at least part of the airflow of the second sub-air inlet chamber 116 flows toward the second air outlet. In an embodiment, the first air outlet is used to output outdoor fresh air from the first sub-air inlet chamber 115 to the indoor side; the second air outlet is used to discharge indoor polluted air from the second sub-air inlet chamber 116 to the outdoor side, or, to filter the indoor polluted air and output it from the second sub-air inlet chamber 116 to the indoor side.

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

[0267] Further optionally, the extended coverage of the first arc segment 1832 and the second arc segment 1842 is defined as follows: when the movable partition 181 rotates to the first position, the first position is that the first outer plate end of the movable partition 181 is located at the distal end of the first arc segment 1832 or the second outer plate end of the movable partition 181 is located at the distal end of the second arc segment 1842, such as Fig.22e As shown, at least part of the cavity space of the second sub-air inlet cavity 116 corresponds to the upstream of the wind path of the first volute air outlet 124, and at least part of the cavity space of the first sub-air inlet cavity 115 corresponds to the upstream of the wind path of the second volute air outlet 125, so that part of the fresh air flow of the first sub-air inlet cavity 115 will be diverted to the second volute air outlet 125, and then discharged to the outdoor side through the second volute air outlet 125, as shown in FIG. Fig.22e and part of the polluted air flow of the second sub-air inlet chamber 116 will be diverted to the first volute air outlet 124, such as Fig.22e The dirty air flow corresponding to the C2 area.

[0268] Therefore, compared with the fixed partition form in the previous embodiment, part of the indoor dirty air replaces part of the outdoor fresh air and is output to the indoor side, and this part of the replaced outdoor fresh air is re-exhausted to the outdoor side. Therefore, when the movable partition 181 is in the first position, the amount of outdoor fresh air output to the indoor side is reduced.

[0269] Further optionally, the extended coverage range of the first arc segment 1832 and the second arc segment 1842 is defined as: when the movable partition 181 rotates to the second position, the first position is that the first outer plate end of the movable partition 181 is located at the proximal end of the first arc segment 1832 or the second outer plate end of the movable partition 181 is located at the proximal end of the second arc segment 1842, such as Figure 22f As shown, all or most of the cavity space of the first sub-air inlet chamber 115 corresponds to the upstream of the wind path of the first volute air outlet 124, and all or most of the cavity space of the second sub-air inlet chamber 116 corresponds to the upstream of the wind path of the second volute air outlet 125, so that all or most of the fresh air flow of the first sub-air inlet chamber 115 will be diverted to the first volute air outlet 124, and all or most of the polluted air flow of the second sub-air inlet chamber 116 will be diverted to the second volute air outlet 125.

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

[0271] Therefore, compared with the use state when the movable partition 181 is in the first position, the amount of outdoor fresh air output to the indoor side is significantly increased when the movable partition 181 is in the second position, and its diversion air supply effect is close to the fixed partition plate form in the previous embodiment.

[0272] In this way, those skilled in the art can move the movable partition 181 between the first position and the second position according to actual needs and select the actual separation air supply position to dynamically adjust the air volume output ratio of outdoor fresh air and indoor polluted air. Among them, when the movable partition 181 moves from the first position to the second position, the proportion of fresh air output through the first volute air outlet 124 gradually increases, and the proportion of polluted air output through the second volute air outlet 125 gradually increases. When the movable partition 181 moves from the second position to the first position, the proportion of fresh air output through the first volute air outlet 124 gradually decreases, and the proportion of polluted air output through the second volute air outlet 125 gradually decreases.

[0273] In the above embodiment, the air filter element 14 of the fresh air module 1 is arranged in a strip shape 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 airflow input from the first air inlet and / or the second air inlet.

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

[0275] In some further optional embodiments not shown in the drawings, the partition component includes a movable partition and a partition driver, and the partition driver can drive the movable partition to move laterally in the air inlet chamber.

[0276] Here, the movable partition can be arranged in the air inlet cavity in a lateral sliding manner, and its lateral moving plane 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 formed and extending in the lateral direction, and accordingly, the partition driver includes a partition driving motor and a partition driving gear, and the partition driving gear and the partition driving rack are meshed and matched, so that the partition driving motor can drive the movable partition to reciprocate 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 an embodiment, the partition driving motor is a bidirectional rotating motor type, so as to selectively drive the partition to move in a first direction or a second direction in the transverse direction. The first direction and the second direction are two opposite directions. Optionally, the first direction is to move toward the side where the third side wall is located, and the second opposite direction is to move toward the side where the fourth side wall is located.

[0278] In this embodiment, similar to the partition plate shown in the previous embodiment, the movable partition plate and at least a portion of the cavity wall of the air inlet cavity are surrounded to form a first sub-air inlet cavity, and is surrounded to form a second sub-air inlet cavity with at least another portion of the cavity wall of the air inlet cavity.

[0279] Alternatively, to ensure the airtightness between the two sub-inlet chambers during the horizontal movement of the movable partition, the inlet chamber can be constructed in the form of a square chamber, or the interior of the inlet chamber is in the form of a square chamber, and the vertical length of the movable partition is consistent with the vertical length of the inlet chamber. As a result, during the horizontal sliding movement of the movable partition, its longitudinal ends can always abut against the opposite side walls of the inlet chamber, reducing the air leakage gap that may be caused during the movement.

[0280] In this way, when the movable partition moves horizontally in the air inlet cavity, the cavity space of the first sub-air inlet cavity and the second sub-air inlet cavity surrounded by it can be changed. For example, when the movable partition moves toward the third side wall, the cavity space of the first sub-air inlet cavity and the corresponding first sub-air outlet have a larger diameter, and the cavity space of the second sub-air inlet cavity and the corresponding second sub-air outlet have a smaller diameter. Alternatively, when the movable partition moves toward the fourth side wall, the cavity space of the first sub-air inlet cavity and the corresponding first sub-air outlet have a smaller diameter, and the cavity space of the second sub-air inlet cavity and the corresponding second sub-air outlet have a larger diameter.

[0281] In combination with the above embodiment, an outdoor air outlet and an indoor return air outlet are spaced apart on the second side wall, wherein the outdoor air outlet is used to deliver outdoor fresh air to the first sub-inlet chamber, and the indoor return air outlet is used to deliver indoor dirty air to the second sub-inlet chamber. Optionally, the lateral movement range of the movable partition is limited to that one longitudinal end portion thereof corresponding to the second side wall is always located between the outdoor air outlet and the indoor return air outlet, so that the outdoor air outlet always corresponds to the first sub-inlet chamber, and the indoor return air outlet always corresponds to the second sub-inlet chamber.

[0282] In the above-mentioned multiple embodiments, the fresh air duct 20 is connected to the first air inlet to introduce outdoor fresh air into the first air inlet cavity 11; and the second air duct channel is connected to the second air outlet to discharge indoor polluted air to the outdoors.

[0283] Optionally, the partition form for separating the air inlet channel 1223 of the impeller 122 shown in the previous embodiment can also be applied to the partition component in this embodiment, so that the partition component can not only dynamically adjust the cavity space of the sub-air inlet chamber 11 in the air inlet chamber 11 during the activity, but also dynamically adjust the channel space change of the air inlet channel 1223 in the fan chamber 12 accordingly, so as to enhance the effect of diverting and supplying air to airflows from different sources.

[0284] In combination with the above-mentioned embodiment, the first partition plate 191 of the partition member is disposed in the air inlet channel 1223 of the impeller 122, and the second partition plate 192 of the partition member is the movable partition plate 181 in this embodiment. The first partition plate 191 is fixed on the movable partition plate 181 and can move with the movable partition plate 181. Figure 22g Here, the first partition plate 191 is a solution of a movable partition plate 181 that is applied to move relative to the air inlet chamber 11 in a rotational manner.

[0285] Optionally, the partition driver 182 can be driven and connected to the first partition plate 191 or the second partition plate 192, and is used to drive the first partition plate 191 to rotate relative to the fan chamber, and the second partition plate 192 to rotate relative to the air inlet chamber 11, so as to change the partition position of the first partition plate 191 relative to the air inlet channel 1223, and the partition position of the second partition plate 192 (movable partition 181) relative to the air inlet chamber 11.

[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 an avoidance groove 1911 for avoiding the impeller driver 126, thereby preventing the first partition plate 191 from interfering with the impeller driver 126 during rotation. Figure 22h shown.

[0287] Here, the avoidance groove 1911 is spaced apart from the impeller driver 126, and under the premise of avoiding contact, the gap between the groove edge and the impeller driver 126 is minimized to enhance the airtight effect and reduce the mixing of airflows in the two air inlet areas within the air inlet channel 1223 through the gap.

[0288] In combination with the forms of the fresh air module 1 shown in the above embodiments, several air exchange modes of the fresh air module 1 of the present application are described below. (Outdoor fresh air is indicated by a solid arrow, and indoor polluted air is indicated by a dotted arrow)

[0289] Optionally, the working mode of the fresh air module 1 includes a fresh air mode. The fresh air mode means that the fresh air module 1 is used to transport outdoor fresh air from the outdoor side to the indoor side. In this mode, the fresh air module 1 does not transport indoor polluted air to the outdoor side. The fresh air mode can supplement outdoor fresh air with better air quality to the indoor side, thereby improving the air quality of the indoor side.

[0290] In some embodiments, in the fresh air mode, outdoor fresh air is delivered to the indoor side via the fresh air duct 20, the air inlet cavity 11, the first indoor air outlet 51 and / or the second indoor air outlet 52. Specifically, in the fresh air mode, the impeller 122 keeps rotating in a set rotation direction (such as a first rotation direction); the wind shield 41 of the integrated switch unit 40 is controlled to move to the first sliding position so that the indoor return air outlet 113 is blocked, and the first air duct channel 231 and the second air duct channel 232 of the fresh air duct 20 are both connected to the first sub-air inlet cavity 115 and the second sub-air inlet cavity 116 of the air inlet cavity 11; the wind blocking block 32 of the air outlet switching mechanism is controlled to be located at the first rotation position, so that the second air duct channel 232 is blocked from the switching air cavity, and the fan cavity 12 is connected to the first indoor air outlet 51 and the second indoor air outlet 52.

[0291] In this way, when the impeller 122 rotates, negative pressure suction is generated on the side of the air inlet chamber 11, attracting outdoor fresh air on the outdoor side to flow toward the indoor side through the first air duct channel 231 and the second air duct channel 232, and enter the air inlet chamber 11 through the outdoor air outlet 114 of the module housing 10. Fig.23a and 23c Afterwards, the outdoor fresh air flows from the air inlet cavity 11 into the fan cavity 12, and then from the first indoor air outlet 51 and the second indoor air outlet 52, as shown in FIG. Figure 23b The arrows show the direction of air flow.

[0292] Alternatively, the working mode of the fresh air module 1 includes a two-way air exchange mode. The two-way air exchange mode means that the fresh air module 1 is used to simultaneously transport outdoor fresh air from the outdoor side to the indoor side, and to transport indoor polluted air from the indoor side to the outdoor side. The two-way air exchange mode can simultaneously replenish outdoor fresh air to the indoor side and exhaust indoor polluted air from the indoor side, thereby achieving synchronous replacement of fresh air and polluted air, which can improve indoor air quality more quickly.

[0293] In some embodiments, in the two-way air exchange mode, it is divided into two flow paths: an outdoor fresh air flow path and an indoor exhaust air flow path. Specifically, in the two-way air exchange mode, the impeller 122 keeps rotating in a set rotation direction (such as a first rotation direction); the wind shield 41 of the integrated switch unit 40 is controlled to move to the second sliding position, so that the indoor return air port 113 is open, and the second fresh air outlet port 2321 of the second air duct channel 232 is blocked; the wind blocking block 32 of the air outlet switching mechanism is controlled to be located at the second rotation position, so that the branch port 2322 of the second air duct channel 232 is connected to the switching air cavity, and the switching air cavity is blocked from the second indoor air outlet 52, so that the fan cavity 12 is connected to the first indoor air outlet 51 and the second air duct channel 232.

[0294] In this way, when the impeller 122 rotates, negative pressure suction is generated on the side of the air inlet chamber 11, attracting outdoor fresh air on the outdoor side and indoor polluted air on the indoor side to flow into the air inlet chamber 11 at the same time. Among them, the outdoor fresh air flow path is that the outdoor fresh air is sequentially transported to the first indoor air outlet 51 through the first air duct channel 231, the first sub-air inlet chamber 115, and the fan chamber 12, and the outdoor fresh air is sent into the indoor environment through the first indoor air outlet 51. Fig.24a and 24c The indoor exhaust air flow path includes indoor polluted air being transported to the second air duct channel 232 through the indoor return air port 113, the second sub-air inlet chamber 116, and the fan chamber 12 in sequence, and the indoor polluted air is finally discharged to the outdoor side through the second air duct channel 232. Figure 24b and 24c The arrows show the direction of air flow.

[0295] Alternatively, the working mode of the fresh air module 1 includes a full return air mode. The full return air mode means that the fresh air module 1 is used to transport at least part of the outdoor polluted air from the indoor side to the outdoor side, and / or, at least part of the indoor polluted air is filtered and purified and then sent back to the indoor side. In this mode, the fresh air module 1 does not transport outdoor fresh air to the indoor side. This mode can be applied to situations where the outdoor ambient air quality is also poor, such as haze weather.

[0296] In some embodiments, in the full return air mode, the indoor polluted air is transported to the outdoor side via the indoor return air port 113, the air inlet chamber 11, the fan chamber 12 and the second air duct channel 232 (exhaust air duct), and / or the indoor polluted air is transported back to the indoor side via the indoor return air port 113, the air inlet chamber 11, the fan chamber 12 and the first indoor air outlet 51. Specifically, in the full return air mode, the impeller 122 keeps rotating in a set rotation direction (such as the first rotation direction); the wind shield plate 41 of the integrated switch unit 40 is controlled to move to the third sliding position so that the outdoor air port 114 is blocked and the indoor return air port 113 is open; the wind blocking block 32 of the air outlet switching mechanism is controlled to be located at the first rotation position or the second rotation position.

[0297] In this way, when the impeller 122 rotates, negative pressure suction is generated on the side of the air inlet chamber 11, which attracts the indoor polluted air on the indoor side to enter the air inlet chamber 11 through the indoor return air port 113 of the module housing 10, and is divided into the first sub-air inlet chamber 115 and the second sub-air inlet chamber 116. Fig.25a The airflow direction is shown by the arrow in the figure; wherein the indoor polluted air of the first sub-air inlet chamber 115 is filtered and purified by the air filter element 14 and then flows into the fan chamber 12, and then is sent back to the indoor environment from the first indoor air outlet 51, such as Fig.25b and 25c shown.

[0298] The indoor polluted air in the second sub-air inlet chamber 116 is filtered and purified by the air filter element 14 and then flows into the fan chamber 12, and then is transported to the switching air chamber. Here, when the air blocking block 32 is in the first rotation position, the part of the indoor polluted air is sent back to the indoor environment from the second indoor air outlet 52. Fig.25b When the wind blocking block 32 is at the second rotation position, the part of the indoor dirty air is discharged from the second air duct channel 232 to the outdoor environment, such as Fig.25c and 25d shown.

[0299] In some optional embodiments, the present application also provides an air conditioner 6, including an air conditioner body and a fresh air module 1 as in any of the above embodiments, such as Fig.26 and 26a shown.

[0300] Optional, combined Fig.26 and 26a As shown, the air conditioner 6 is a wall-mounted air conditioner. The air conditioner body includes an indoor unit casing 61 and a heat exchange component and a fresh air module 1 placed inside the indoor unit casing 61. Optionally, the heat exchange component is arranged in the middle of the indoor unit casing 61 and in a space on one side thereof, and the fresh air module 1 is arranged in a space on the other side of the indoor unit casing 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. 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 perform heat exchange with the return air flow flowing through the air duct of the indoor heat exchanger 62. 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 casing 61 is also provided with a first casing air outlet 611, a second casing air outlet 612 and a casing return air outlet 613. Among them, the first indoor air outlet 51 of the fresh air module 1 corresponds to the first casing air outlet 611 and is interconnected, and the second indoor air outlet 52 corresponds to the second casing air outlet 612 and is interconnected, 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 casing air outlet 611 and the second casing air outlet 612. And, the indoor return air outlet 113 of the fresh air module 1 corresponds to the casing return air outlet 613 and is interconnected, so that the indoor polluted air can flow into the fresh air module 1 through the casing return air outlet 613.
