[0002] With the prosperous development of the country and the progress of science and technology, the quality of people's life has been gradually improved, and the application of air conditioners has become more and more common. At the same time, the development of industry has caused certain damage to the environment on which people depend for survival, and there are more and more dust particles in the air. In addition, seasonal catkins, pollen, etc. will also cause troubles to people. In order to prevent these dust particles, catkins, pollen, etc. from entering the home, people usually close the doors and windows when going out, but long-term closure will cause the home to be stuffy and the air to be not fresh. In addition, users also close the doors and windows when using the air conditioner at home. After running for a long time like this, the carbon dioxide concentration in the indoor space will become higher and higher, and the oxygen content will become lower and lower, and users will also feel stuffy and the air is not fresh.

[0003] Therefore, some families will choose to install a fresh air machine or an air conditioner with a fresh air module to introduce fresh air from the outside into the indoor space through the fresh air machine or the fresh air module of the air conditioner, so as to improve the air quality of the indoor space. However, the current fresh air machines or the fresh air modules of air conditioners usually only have the function of introducing fresh air, and the functions are relatively single.

[0004] Correspondingly, the field needs a new technical solution to solve the above problems. Summary of the Utility Model

[0005] The utility model aims to solve the above technical problems, that is, to solve the problem that the functions of the fresh air module of the existing fresh air machine or air conditioner are relatively single.

[0006] In a first aspect, the utility model provides a fresh air module, which includes a housing and a fan arranged in the housing. A fresh air inlet and a fresh air outlet are arranged on the housing.

[0012] In the preferred technical solution of the above fresh air module, the fresh air module further includes a power member. The power member is connected to the blocking member. The power member is configured to be able to drive the blocking member to move so as to block the fresh air inlet or the air return opening.

[0013] In the preferred technical solution of the above fresh air module, the power member is a driving motor. The blocking member is a baffle plate and a connecting portion arranged on the baffle plate. The connecting portion is connected to the power output end of the driving motor.

[0014] In the preferred technical solution of the above fresh air module, the fresh air module further includes an air duct assembly. The air duct assembly includes a fresh air duct and an air cap. The first end of the fresh air duct is connected to the fresh air inlet. The second end of the fresh air duct extends to the outside of the room. The air cap is arranged at the second end of the fresh air duct.

[0015] In the technical solution of the present utility model, a fresh air inlet, a fresh air outlet and an air return opening are arranged on the housing of the fresh air module. The fresh air inlet communicates with the outside of the room. Both the fresh air outlet and the air return opening communicate with the indoor space. The fresh air inlet and the air return opening are arranged on the air inlet side of the fan. The fresh air outlet is arranged on the air outlet side of the fan. In this way, under the action of the fan, fresh air in the outside can be introduced into the housing through the fresh air inlet, and then sent into the indoor space through the fresh air outlet to improve the air quality of the indoor space. Also, the air in the indoor space can be introduced into the housing through the air return opening, and then sent back into the indoor space through the fresh air outlet to strengthen the circulation of the indoor air.

When the air in the indoor space enters the housing, the purification device can purify this air to purify the indoor air while promoting air circulation and better improve the comfort level.

[0017] Further, the fresh air module further includes a blocking member movably disposed inside the housing. The fresh air inlet or the air return opening can be blocked by this blocking member. In this way, when fresh air needs to be introduced, the blocking member is moved away to allow fresh outdoor air to enter the indoor space through the fresh air inlet and the fresh air outlet in sequence to improve the indoor air quality. When fresh air is not needed, the blocking member is moved to the fresh air inlet to block the fresh air inlet, so that the air in the indoor space enters the housing through the air return opening and then is sent back to the indoor space through the fresh air outlet to enhance the indoor air circulation and improve the comfort level.

[0018] In a second aspect, the present utility model further provides an air conditioner, which includes the fresh air module described in any of the foregoing solutions.

[0029] The preferred implementation manners of the present utility model will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model. It should be noted that although the fresh air module is set on a cabinet air conditioner as an example in this embodiment, it can obviously also be set on other types of air conditioners such as wall-mounted air conditioners and central air conditioners or fresh air equipment (such as fresh air fans, etc.).

[0030] It should be noted that in the description of the present utility model, the terms indicating directions or positional relationships such as "upper", "lower", "inner", "outer", "right", etc. are based on the directions or positional relationships shown in the drawings. This is only for convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0031] In addition, it should also be noted that in the description of the present application, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0032] The current fresh air modules of fresh air machines or air conditioners usually only have the function of introducing fresh air, and the function is relatively single. Therefore, by additionally providing a return air outlet on the air inlet side of the fan in the fresh air module of this application, the fresh air module can have the function of enhancing indoor air circulation in addition to the function of introducing fresh air, effectively improving the user experience.

[0033] The following will Figures 1 to 6 describe the possible implementation manners of the fresh air module of the present utility model.

[0034] As Figure 1 、 Figure 2 、 Figure 4 shown, the indoor unit is configured with a fresh air module. The fresh air module includes a housing 1 and a fan. The fan is a centrifugal fan 2. A fresh air inlet 121 and a fresh air outlet 111 are provided on the housing 1. The fresh air inlet 121 is generally circular and is located on the air inlet side of the centrifugal fan 2, and it communicates with the outside. The fresh air outlet 111 is located on the air outlet side of the centrifugal fan 2, and it communicates with the indoor space. In this way, under the action of the centrifugal fan 2, outdoor fresh air enters the housing 1 through the fresh air inlet 121 and then is sent into the indoor space through the fresh air outlet 111, so as to achieve the purpose of improving the air quality of the indoor space. A return air outlet 122 is also provided on the housing 1. The return air outlet 122 communicates with the indoor space and is located on the air inlet side of the centrifugal fan 2. In this way, the air in the indoor space can also enter the housing 1 through the return air outlet 122 under the action of the centrifugal fan 2 and then be sent back to the indoor space through the fresh air outlet 111, promoting the circulation and flow of indoor air. That is to say, the present utility model makes the fresh air module have both fresh air function and circulation function by additionally providing a return air outlet 122 on the air inlet side of the fan, which can not only meet people's demand for fresh air but also improve the comfort, effectively improving the user experience.

[0035] It should be noted that the fan can also be other types of fans such as axial flow fans, cross-flow fans, mixed (oblique) flow fans, etc. The specific type is not limited in this application as long as it can introduce fresh air or the air in the indoor space into the housing 1 and send it out from the fresh air outlet 111.

[0036] As Figures 1 to 4As shown, the floor-standing air conditioner includes an indoor unit (not shown), and the indoor unit (not shown) includes a casing (not shown), a heat exchanger (not shown) and an indoor fan (not shown) provided in the casing. An air inlet (not shown) and an air outlet (not shown) are provided on the casing, and an air duct is formed between the air inlet and the air outlet. Under the action of the indoor fan, the air in the indoor space enters the air duct through the air inlet, exchanges heat with the heat exchanger and then returns to the indoor space. The fresh air module of the present utility model is arranged in the indoor unit, and its housing 1 includes a first housing 11 and a second housing 12, and both the first housing 11 and the second housing 12 are generally in a cover-like structure. The first housing 11 is buckled on the inner wall of the casing, and a blower chamber is formed by enclosing with it. A centrifugal blower 2 is arranged in the blower chamber. A communication structure 112 is provided at the bottom of the first housing 11 (that is, the side surface of the first housing 11 facing the second housing 12), and the communication structure 112 is generally a circular grille, and the circular grille is aligned with the air inlet of the centrifugal blower 2 so as not to affect the air guiding ability of the centrifugal blower 2. The second housing 12 is buckled on the outer side of the bottom of the first housing 11 by means of screwing and clamping, and an air inlet chamber communicating with the blower chamber is formed by enclosing between the two. A fresh air outlet 111 is provided on the first housing 11, and a fresh air duct 3 is provided on the first housing 11 at a position corresponding to the fresh air outlet 111. The fresh air duct 3 is arranged in the casing, and an indoor outlet (not shown) is provided on the casing, and the fresh air duct 3 communicates with the indoor outlet. A fresh air inlet 121 and a return air outlet 122 are both provided at the bottom of the second housing 12 (that is, the side surface of the second housing 12 opposite to the bottom of the first housing 11), and the fresh air inlet 121 and the return air outlet 122 and the communication structure 112 are respectively arranged on two opposite side surfaces of the second housing 12 and the first housing 11, and through holes are formed in the casing at corresponding positions, and the fresh air inlet 121 and the return air outlet 122 respectively communicate with the corresponding through holes. The fresh air module of the present utility model further includes a purification device 4, and the purification device 4 is arranged in the air inlet chamber by means of clamping, screwing, etc., and the air entering the air inlet chamber can be purified by the purification device 4, such as dust removal and sterilization.

[0037] Through such an arrangement, when the centrifugal blower 2 is running, after the fresh air enters the air inlet chamber through the fresh air inlet 121, the fresh air is purified by the purification device 4 and then enters the indoor space through the communication structure 112, the fresh air outlet 111, the fresh air duct 3 and the indoor outlet on the casing, so as to avoid secondary pollution to the indoor space caused by dust, bacteria, etc. carried in the fresh air and better improve the indoor air quality; after the air in the indoor space enters the air inlet chamber, the indoor air is purified by the purification device 4 and then enters the indoor space through the communication structure 112, the fresh air outlet 111, the fresh air duct 3 and the indoor outlet on the casing. In this way, it can not only promote the indoor air circulation, but also purify the indoor air, thus better improving the comfort level.

[0038] It should be noted that the purification device 4 may not be arranged in the air inlet chamber, but in other possible positions such as the fan chamber or the fresh air duct 3, as long as it can purify the air flowing through the housing 1. The purification device 4 may be a HEPA filter module, an IFD dust removal module, an electrostatic dust removal module, a negative ion module or other possible modules. In this embodiment, the specific type of the purification device 4 is not limited, as long as it can purify the air flowing through the housing 1.

[0039] It should be noted that the housing 1 may also be arranged in other ways. For example, a relatively closed accommodation space is formed in the housing 1, and the purification device 4 and the centrifugal fan 2 are arranged in this accommodation space along the air flow direction. The fresh air inlet 121, the fresh air outlet 111 and the return air inlet 122 are all arranged on the housing 1. The fresh air inlet 121 and the return air inlet 122 are located on the air inlet side of the centrifugal fan 2, and the fresh air outlet 111 is located on the air outlet side of the centrifugal fan 2. Of course, the housing 1 may also be arranged in other possible ways. On the premise of not deviating from the basic principle of the present invention, those skilled in the art can flexibly select the specific setting form of the housing 1 according to the specific application scenario, as long as it can accommodate the centrifugal fan 2 and the purification device 4 and realize the fresh air function and the circulation function of the fresh air module.

[0040] As Figures 1 to 6 shown, the fresh air module further includes a blocking member 5 and a power member. The blocking member 5 includes a blocking member body 51 and a connecting portion 52. The blocking member body 51 is generally circular, and the connecting portion 52 is generally a handle extending from the blocking member 5. A connecting hole is provided at the end of the connecting portion 52. The housing 1 further includes a mounting plate 13, which is arranged on the outer side of the bottom of the second housing 12 by means of screwing and clamping. The mounting plate 13 is correspondingly formed with a first opening 131 and a second opening 132 at positions corresponding to the fresh air inlet 121 and the return air inlet 122. The sizes of the first opening 131 and the second opening 132 are generally equivalent to the sizes of the fresh air inlet 121 and the return air inlet 122. When the blocking member 5 blocks the fresh air inlet 121 and the return air inlet 122, the first opening 131 and the second opening 132 are also blocked at the same time. A flat mounting space is formed between the mounting plate 13 and the bottom of the second housing 12, and the blocking member 5 is arranged in this mounting space, so that the blocking member 5 is isolated from other components in the air inlet chamber such as the purification device 4, avoiding mutual influence.

[0041] The outer surface of the mounting plate 13 is provided with two mounting posts 133, and each mounting post 133 is respectively provided with a mounting hole 1331. The power component can be a driving motor 6, and two lugs 61 extend outward from the driving motor 6, and each of the two lugs 61 is respectively provided with a screw hole 611. Align the two lugs 61 of the driving motor 6 with the two mounting posts 133 respectively, and fasteners (such as screws or bolts, etc.) pass through the screw holes 611 and are connected to the mounting holes 1331, so that the driving motor 6 is installed on the housing 1. Three limiting ribs 134 are arranged on the outer side of the mounting post 133, and the three limiting ribs 134 are distributed along the circumferential direction of the mounting post 133. One side of each limiting rib 134 facing the mounting post 133 is set as an inclined surface, so as to guide the lug 61 to the position where the mounting post 133 is located during installation, and at the same time can limit the outward movement of the lug 61, making it more convenient for subsequent fastening and fixing. A through hole (not shown) is also provided on the mounting plate 13, and the shape of the through hole is roughly similar to the shape of the power output end of the driving motor 6 and is located between the two mounting posts 133. The power output end of the driving motor 6 passes through the through hole and is connected to the connection hole on the connecting portion 52, so that the connection between the power component and the blocking component 5 is realized, and the blocking component body 51 can be driven by the driving motor 6 to move between the fresh air inlet 121 and the return air outlet 122. A receiving position is formed in the installation space, and the receiving position is roughly in a peach shape. The blocking component 5 is arranged in the receiving position. When the blocking component body 51 blocks the return air outlet 122, the blocking component 5 is roughly in contact with the upper side edge of the receiving position. When the blocking component body 51 blocks the fresh air inlet 121, the blocking component 5 is roughly in contact with the lower side edge of the receiving position, so that the blocking component 5 can be limited within a certain area.

[0042] Through the above setting method, when fresh air needs to be introduced, the blocking component body 51 is moved from the fresh air inlet 121 to the return air outlet 122 and blocks the return air outlet 122. In this way, under the action of the centrifugal fan 2, the outdoor fresh air can enter the indoor space in sequence through the first opening 131, the fresh air inlet 121, the purification device 4, the fresh air outlet 111 and the fresh air duct 3, so as to achieve the purpose of improving the indoor air quality; when fresh air is not needed, the blocking component 5 is moved from the return air outlet 122 to the fresh air inlet 121 and blocks the fresh air inlet 121. In this way, under the action of the centrifugal fan 2, the air in the indoor space can return to the indoor space in sequence through the second opening 132, the return air outlet 122, the purification device 4, the fresh air outlet 111 and the fresh air duct 3, so as to achieve the purpose of purifying the indoor air, enhancing the indoor air circulation and improving the comfort.

[0043] It should be noted that the power component can also be other possible power components such as an air pump or a hydraulic pump, as long as it can drive the blocking component 5 to move and block the fresh air inlet 121 or the return air outlet 122. Of course, the fresh air module of the present application may not include a power component, but rely on the user to manually move the blocking component 5.

[0044] It should be noted that the blocking component 5 can also be set in other possible shapes such as square, rectangular, oval, polygonal, irregular, etc., as long as it can block the fresh air inlet 121 and the return air outlet 122. Obviously, the blocking component 5 can also not be provided.

[0045] It should be noted that the housing 1 may not include the mounting plate 13. In this case, the drive motor 6 can be directly installed on the outer side of the bottom of the second housing 12, and the blocking component 5 can be installed on the inner side of the bottom of the second housing 12.

[0046] As Figures 4 to 6 shown and in the orientation Figure 4 shown, the return air outlet 122 includes two regions. One region is a circular region 1221, which is arranged above the fresh air inlet 121 and is opposite to the second opening 132 on the mounting plate 13. Its size is approximately the same as that of the second opening 132 and is approximately equivalent to the fresh air inlet 121. In this way, as long as the size of the blocking component 5 is set to be approximately the same as that of the fresh air inlet 121, the need to block the fresh air inlet 121 or the return air outlet 122 can be met. A radial grille is provided at the circular region 1221, and through this grille, sundries in the indoor space can be blocked from entering the air inlet chamber. The other region is a long strip region 1222, which is formed by an array of 8 square holes and is arranged on the right side of the fresh air inlet 121 and the circular region 1221. When the centrifugal fan 2 is running and the fresh air inlet 121 is blocked, the air in the indoor space can enter the air inlet chamber through both the circular region 1221 and the long strip region 1222 at the same time. When fresh air needs to be introduced, the blocking component 5 is used to block the circular region 1221, and the fresh air is introduced into the air inlet chamber through the fresh air inlet 121. At this time, a small amount of indoor air will also enter the air inlet chamber through the long strip region 1222. This part of the indoor air is less and will not affect the introduction of fresh air. At the same time, it can also purify the indoor air. In this way, the introduction of fresh air and the circulation of indoor air can be separated from each other and do not interfere with each other, so that fresh air can be introduced better and the circulation of indoor air can be promoted.

[0047] It should be noted that the circular area 1221 can also be set into other possible shapes such as a rectangle, an ellipse, a triangle, etc. Of course, the long strip area 1222 can also be formed by an array of square holes with a smaller number such as 7, 6, 5, etc., or a larger number such as 9, 10, 11, etc. Of course, the long strip area 1222 can also be formed by an array of holes with other possible shapes such as multiple circular holes, rectangular holes, and irregular holes. Of course, the air return opening 122 can also only include the circular area 1221 and not include the long strip area 1222. Obviously, the air return opening 122 can also not be arranged at a position close to the fresh air inlet 121, that is, the air return opening 122 can also not be arranged at the bottom of the second housing 12, but on other sides of the second housing 12. Without departing from the basic principle of the present application, those skilled in the art can flexibly select the specific setting method and specific setting position of the air return opening 122 according to the specific application scenario, as long as the indoor air can enter the air inlet chamber through the air return opening 122, promote the indoor air circulation, and purify the air.

[0048] As Figure 1 , Figure 2 and Figure 6 shown, the mounting plate 13 extends outwardly with an air duct interface 135 at a position corresponding to the first opening 131. The air duct interface 135 is generally a cylindrical structure, and four positioning posts 1351 are provided on its outer wall. The fresh air module further includes an air duct assembly 7. The air duct assembly 7 includes a fresh air duct 71 and an air cap 72. The fresh air duct 71 is generally a threaded hose, and its first end is connected to the fresh air inlet 121 and the second end extends to the outside of the room. A connector 711 is provided at the first end of the fresh air duct 71, and four L-shaped through holes (not shown) that are respectively matched with the positioning posts 1351 are provided on the connector 711. During installation, after the first end of the connector 711 is inserted into the air duct interface 135, the positioning posts 1351 can be made to cooperate with the L-shaped through holes by screwing, so as to realize the connection between the connector 711 and the air duct interface 135, that is, to realize the connection between the fresh air duct 71 and the fresh air inlet 121, which is convenient and reliable, and thus can ensure the introduction of fresh air. The air cap 72 is provided at the second end of the fresh air duct 71. The air cap 72 is generally a tubular structure, with a closed upper part and gratings provided on the lower part and the end surface respectively. In this way, a sufficient amount of fresh air can enter the fresh air duct 71 through the gratings and then enter the indoor space. The closed design of the upper part of the air cap 72 and the gratings provided on the lower part and the cross section can also prevent rainwater, outdoor sundries (such as catkins, leaves, etc.) from entering the fresh air duct 71 and then entering the fresh air module. Of course, the through holes on the connector 711 that are matched with the positioning posts 1351 can also be other possible shapes such as circular and curved. Obviously, the connector 711 can also be connected to the air duct interface 135 by screwing, plugging, etc. Of course, the air duct assembly 7 can also only include the fresh air duct 71 and not include the air cap 72.

[0049] In summary, in the preferred technical solution of the present utility model, by providing an air return port 122 and a fresh air inlet 121 on the air inlet side of the fan, the fresh air module can have both fresh air function and circulation function, which can not only meet people's demand for fresh air, but also improve comfort, effectively enhancing the user experience. Through the setting of the purification device 4, it can avoid secondary pollution of the indoor space caused by dust, bacteria, etc. entrained in the fresh air when introducing fresh air, and purify the indoor air while promoting indoor air circulation, thus being able to better improve the indoor air quality and enhance comfort. Through the setting of the blocking member 5 and the power member, the blocking member 5 can be used to block the air return port 122 and the fresh air inlet 121 as needed, so that the introduction of fresh air and the indoor air circulation can be separated from each other without interference, better introducing fresh air and promoting indoor air circulation.

[0050] In addition, the present utility model also provides an air conditioner, which includes the fresh air module described in any of the foregoing solutions.

[0051] It should be noted that this air conditioner has all the technical effects of the foregoing fresh air module and will not be elaborated herein.

[0052] Of course, the above-mentioned replaceable embodiments can be used in cross-combination with each other, and the replaceable embodiments and the preferred embodiments can also be used in cross-combination, so as to combine new embodiments to be applicable to more specific application scenarios.

[0053] In addition, those skilled in the art can understand that although some of the embodiments described herein include certain features included in other embodiments rather than other features, the combination of the features of different embodiments means that it is within the scope of the present utility model and forms different embodiments.
