[0028] In order to solve the problem of low environmental adaptability of the new fan in the prior art, the present application provides a new fan.

[0029] As shown in Figures 1 to 3 A new fan, comprising a housing 10 and an adjusting assembly 20, the housing 10 has a fresh air channel and an exhaust air channel, the housing 10 further has a fresh air inlet 11 and a fresh air outlet 12 in communication with the fresh air channel, and an exhaust air inlet 13 and an exhaust air outlet 14 in communication with the exhaust air channel; the adjusting assembly 20 has a communication cavity and a first port 21 and a second port 22 in communication with the communication cavity, the fresh air outlet 12 and the exhaust air inlet 13 are selectively communicated with the first port 21 and the second port 22 through the communication cavity.

[0030] ​​The first port 21 and the second port 22 on the adjusting assembly 20 can be selectively matched with the fresh air outlet 12 and the exhaust air inlet 13 through the communication cavity, that is, the first port 21 can be matched with the fresh air outlet 12 and the second port 22 can be matched with the exhaust air inlet 13, at this time, the first port 21 serves as the outlet of fresh air and the second port 22 serves as the inlet of exhaust air, and the first port 21 and the second port 22 are respectively matched with the corresponding pipe network; or the first port 21 can be matched with the exhaust air inlet 13 and the second port 22 can be matched with the fresh air outlet 12, at this time, the first port 21 serves as the inlet of exhaust air and the second port 22 serves as the outlet of fresh air. In this way, the functions of the first port 21 and the second port 22 can be adaptively adjusted without changing the positions of the first port 21 and the second port 22, so that the first port 21 and the second port 22 can be matched with the optimal pipe network according to the needs, the pipe networks do not need to be arranged in cross, thereby reducing the installation complexity of the pipe and the installation cost, facilitating the construction, and improving the adaptability of the fresh air machine to the environment. In addition to the above-mentioned mode, the fresh air outlet 12 can also be communicated with the first port 21 and the second port 22 at the same time, at this time, the fresh air machine is in the positive pressure fresh air mode for the whole house, similarly, the exhaust air inlet 13 can also be communicated with the first port 21 and the second port 22 at the same time, at this time, the fresh air machine is in the negative pressure exhaust air mode for the whole house, in this way, the fresh air machine can supply fresh air or exhaust air in multiple modes, and the airflow of the whole house can be freely switched.

[0031] The fresh air machine further includes a fresh air unit 30 and an exhaust air unit 40, the fresh air unit 30 is arranged at the fresh air passage, the exhaust air unit 40 is arranged at the exhaust air passage, and the fresh air unit 30 and the exhaust air unit 40 can include a fan, a core and other components according to the needs, the part of the structure can adopt the related structure of the existing fan unit, and the embodiment will not be described again. The fresh air inlet 11 and the exhaust air outlet 14 on the shell 10 are located at the side of the shell 10 away from the fresh air outlet 12 and the exhaust air inlet 13, since the fresh air inlet 11 and the exhaust air outlet 14 are generally communicated with the outdoor, the positions of the fresh air inlet 11 and the exhaust air outlet 14 generally do not need to be changed, so the adjusting assembly 20 does not need to be arranged at this position.

[0032] In the embodiment, the communication cavity includes a first adjustment cavity 23 and a second adjustment cavity 24 which are independent of each other. Since the fresh air outlet 12 and the exhaust air inlet 13 need to correspond to the fresh air unit 30 and the exhaust air unit 40, and the positions of the fresh air unit 30 and the exhaust air unit 40 are fixed, the relationship between the fresh air outlet 12 and the exhaust air inlet 13 and each adjustment cavity is determined, i.e. the fresh air outlet 12 is in communication with the first adjustment cavity 23 and is not in communication with the second adjustment cavity 24, and the exhaust air inlet 13 is in communication with the second adjustment cavity 24 and is not in communication with the first adjustment cavity 23. The selective communication is achieved by changing the relationship between the adjustment cavity and the port, i.e. the communication relationship between the first adjustment cavity 23 and the first port 21 and the second port 22 can be adjusted, and the communication relationship between the second adjustment cavity and the first port 21 and the second port 22 can be adjusted, so as to achieve the effect that the fresh air outlet 12 is selectively in communication with the first port 21 and / or the second port 22 through the first adjustment cavity 23, and the exhaust air inlet 13 is selectively in communication with the first port 21 and / or the second port 22 through the second adjustment cavity 24.

[0033] The communication relationship between the adjustment cavity and the port in the embodiment is achieved by an adjusting member. Specifically, the adjusting assembly 20 further includes a first adjusting member 25 and a second adjusting member 26. The first adjusting member 25 is adjustably arranged in the first adjustment cavity 23, and by changing the first adjusting member 25, the fresh air outlet 12 is selectively in communication with the first port 21 and / or the second port 22. Similarly, the second adjusting member 26 is adjustably arranged in the second adjustment cavity 24, and by changing the position of the second adjusting member 26, the exhaust air inlet 13 is selectively in communication with the first port 21 and / or the second port 22.

[0034] The adjusting member in the embodiment adopts a plate-shaped structure, i.e. the first adjusting member 25 includes a first adjusting plate, and the second adjusting member 26 includes a second adjusting plate. Specifically, the first adjusting plate is arranged in the first adjustment cavity 23, and the second adjusting plate is arranged in the second adjustment cavity 24. Figure 2As shown, the first adjusting plate is movably arranged in the first adjusting cavity 23, and the moving direction of the first adjusting plate is the same as the arrangement direction of the first port 21 and the second port 22. Due to the arrangement of the first adjusting plate, the first adjusting plate can divide the first adjusting cavity 23 into a first sub-cavity and a second sub-cavity, and the first sub-cavity and the second sub-cavity are not in communication. The fresh air outlet 12, the first port 21 and the second port 22 can be located in different sub-cavities as needed. In this way, the two air ports located in the same sub-cavity are in a communication relationship. For example, the fresh air outlet 12 and the first port 21 are located in the first sub-cavity, and the second port 22 is located in the second sub-cavity. Then, the fresh air outlet 12 is in communication with the first port 21 and not in communication with the second port 22. In this way, the first port 21 realizes the outlet function of fresh air. When it is necessary to switch the communication relationship, the position of the first adjusting plate can be changed to adjust the area of the first sub-cavity and the second sub-cavity, so as to adjust the communication relationship between the fresh air outlet 12, the first sub-cavity, the second sub-cavity, the first port 21 and the second port 22, realize the change of the communication relationship between the fresh air outlet 12 and the first port 21 and / or the second port 22, and further realize the switching of different functions of the first port 21 and the second port 22.

[0035] In order to realize the switching of the communication relationship between the fresh air outlet 12 and the first port 21 and the second port 22, the first adjusting plate of the embodiment has a first position and a second position. When the first adjusting member 25 is located at the first position, the fresh air outlet 12 and the first port 21 are located in the same sub-cavity, and the second port 22 is located in the other sub-cavity. At this time, the fresh air outlet 12 is in communication with the first port 21, and the first port 21 functions as the outlet of fresh air and is connected with the fresh air pipe network. When the first adjusting member 25 is located at the second position, the fresh air outlet 12 and the second port 22 are located in the same sub-cavity, and the first port 21 is located in the other sub-cavity. At this time, the fresh air outlet 12 is in communication with the second port 22, and the second port 22 functions as the outlet of fresh air and is connected with the fresh air pipe network.

[0036] Similar to the above-mentioned first adjusting plate, as shown in FIG. 6, the second adjusting plate is movably arranged in the second adjusting cavity 24, and the moving direction of the second adjusting plate is the same as the arrangement direction of the third port 31 and the fourth port 32. Due to the arrangement of the second adjusting plate, the second adjusting plate can divide the second adjusting cavity 24 into a third sub-cavity and a fourth sub-cavity, and the third sub-cavity and the fourth sub-cavity are not in communication. The fresh air outlet 13, the third port 31 and the fourth port 32 can be located in different sub-cavities as needed. In this way, the two air ports located in the same sub-cavity are in a communication relationship. For example, the fresh air outlet 13 and the third port 31 are located in the third sub-cavity, and the fourth port 32 is located in the fourth sub-cavity. Then, the fresh air outlet 13 is in communication with the third port 31 and not in communication with the fourth port 32. In this way, the third port 31 realizes the outlet function of fresh air. When it is necessary to switch the communication relationship, the position of the second adjusting plate can be changed to adjust the area of the third sub-cavity and the fourth sub-cavity, so as to adjust the communication relationship between the fresh air outlet 13, the third sub-cavity, the fourth sub-cavity, the third port 31 and the fourth port 32, realize the change of the communication relationship between the fresh air outlet 13 and the third port 31 and / or the fourth port 32, and further realize the switching of different functions of the third port 31 and the fourth port 32. Figure 3As shown, the second adjusting plate is also movably arranged in the second adjusting cavity 24, and it also divides the second adjusting cavity 24 into a third sub-cavity and a fourth sub-cavity, and the air exhaust inlet 13, the first port 21 and the second port 22 are located in different sub-cavities as needed, so as to realize the communication between the air exhaust inlet 13 and the first port 21 and / or the second port 22. When it is needed to change the communication relationship between the air exhaust inlet 13 and the first port 21 and the second port 22, the position of the second adjusting plate is adjusted, so as to adjust the communication relationship between the air exhaust inlet 13, the third sub-cavity, the fourth sub-cavity, the first port 21 and the second port 22, thereby realizing the change of the communication relationship between the air exhaust inlet 13 and the first port 21 and / or the second port 22, and further realizing the switching of the different functions of the first port 21 and the second port 22.

[0037] Similarly, the second adjusting plate of the embodiment has a third position and a fourth position. When the second adjusting plate is located at the third position, the air exhaust inlet 13 and the second port 22 are located in the same sub-cavity, and the first port 21 is located in the other sub-cavity. At this time, the air exhaust inlet 13 communicates with the second port 22, and the second port 22 functions as an air exhaust inlet and is connected with the air exhaust pipe network. When the second adjusting plate is located at the fourth position, the air exhaust inlet 13 and the first port 21 are located in the same sub-cavity, and the second port 22 is located in the other sub-cavity. At this time, the air exhaust inlet 13 communicates with the first port 21, and the first port 21 functions as an air exhaust inlet and is connected with the air exhaust pipe network.

[0038] It should be noted that, since the fresh air and the exhaust air of the fresh air machine need to be considered as a whole, in actual use, the positions of the first adjusting plate and the second adjusting plate need to be adjusted as a whole. For example, if the first port 21 needs to be connected with the fresh air pipe network, and the second port 22 needs to be connected with the exhaust air pipe network, the first adjusting plate should be located at the first position, and at the same time, the second adjusting plate should be located at the third position. If the second port 22 needs to be connected with the fresh air pipe network, and the first port 21 needs to be connected with the exhaust air pipe network, the first adjusting plate should be located at the second position, and at the same time, the second adjusting plate should be located at the fourth position. Figure 1 、 2 In FIGS. 1 to 3, two first adjusting plates, three first adjusting plates and three second adjusting plates are respectively shown, which represent different positions of each adjusting plate, and not that multiple first adjusting plates and second adjusting plates are arranged. Of course, the first adjusting plate and the second adjusting plate can also be arranged with multiple.

[0039] Of course, the first adjusting member 25 and the second adjusting member 26 can also adopt other structural forms as required, for example, a hemispherical structure that can shield the ports, and the like. In addition to the movable arrangement, the first adjusting member 25 and the second adjusting member 26 can also be arranged in a slidable manner in the communication cavity, or arranged in a flip manner in the communication cavity, as long as the adjusting cavity can be separated and the switching between the fresh air outlet 12, the exhaust air inlet 13, and the first port 21 and the second port 22 can be realized.

[0040] In the embodiment, the fresh air outlet 12 and the exhaust air inlet 13 are located on the same side of the adjusting assembly 20 and are located on the side of the adjusting assembly 20 close to the shell 10, while the first port 21 and the second port 22 are located on the opposite side, i.e., on the side of the adjusting assembly 20 away from the shell 10. Meanwhile, the fresh air outlet 12 and the first port 21 are arranged opposite to each other, and the exhaust air inlet 13 and the second port 22 are arranged opposite to each other, and further preferably, the fresh air outlet 12 and the first port 21 are coaxially arranged, and the exhaust air inlet 13 and the second port 22 are coaxially arranged, so that the overall arrangement is more smooth and conducive to the flow of air. Of course, the arrangement between the fresh air outlet 12, the exhaust air inlet 13, the first port 21, and the second port 22 is not limited to the above-mentioned manner of the embodiment, and can be adjusted as required.

[0041] In order to adapt to the above-mentioned arrangement, the first adjusting member 25 and the second adjusting member 26 are respectively arranged in an inclined manner in the first adjusting cavity 23 and the second adjusting cavity 24, and the inclined directions of the two are opposite, the first adjusting member 25 extends in the first adjusting cavity 23 from the side of the fresh air outlet 12 to the second port 22, and the second adjusting member 26 extends in the second adjusting cavity 24 from the side of the exhaust air inlet 13 to the first port 21. In this way, when the first adjusting member 25 and the second adjusting member 26 move, the cooperation relationship between the fresh air outlet 12, the exhaust air inlet 13, and the first port 21 and the second port 22 can be changed. Of course, when the arrangement between the fresh air outlet 12, the exhaust air inlet 13, the first port 21, and the second port 22 is adjusted, the specific arrangement of the first adjusting member 25 and the second adjusting member 26 can also be adjusted as required, and can also be arranged in a parallel manner with the axis of the port.

[0042] In order to realize the automatic adjustment of the fresh air machine, the fresh air machine of the embodiment further comprises a driving mechanism, which can adopt components such as a stepping motor as needed, and can additionally cooperate with transmission components such as gears, and the driving mechanism is drivingly connected with the first adjusting piece 25 and / or the second adjusting piece 26 through the transmission components, so as to realize the automatic adjustment of the first adjusting piece 25 and the second adjusting piece 26. The number of the driving mechanism can be set as needed, which can be only one, and can be cooperated with the first adjusting piece 25 and the second adjusting piece 26, or can be multiple, and can be cooperated with the first adjusting piece 25 and the second adjusting piece 26 respectively.

[0043] The adjusting assembly 20 of the embodiment is structurally specifically composed of an outer shell 28 and a partition plate 27, wherein the outer shell 28 is connected with the shell 10, and the shape of the outer shell 28 can be set as needed. The outer shell 28 of the embodiment adopts a long strip shape, and is connected with the side surface of the flat rectangular shell 10. The length direction of the outer shell 28 is along the width direction of the shell 10, and the width direction of the outer shell 28 is along the length direction of the shell 10, and the thickness directions are consistent. In this way, the outer shell 28 is equivalent to extending a small part on the side surface of the shell 10, so as to form a communication cavity and reduce the influence on the original devices and pipelines in the shell 10. The first port 21 and the second port 22 are located at the side surface of the outer shell 28, and are located on the side surface of the outer shell 28 away from the fresh air outlet 12 and the exhaust air inlet 13. The outer shell 28 has a communication cavity, and the partition plate 27 is arranged in the outer shell 28, so as to divide the communication cavity of the outer shell 28 into two layers in the thickness direction of the fresh air machine, and form a first adjusting cavity 23 and a second adjusting cavity 24. The fresh air outlet 12 of the fresh air unit 30 and the exhaust air inlet 13 of the exhaust air unit 40 are also divided into two layers, so as to cooperate with the first adjusting cavity 23 and the second adjusting cavity 24 in the two layers. Since the first port 21 and the second port 22 need to be communicated with the first adjusting cavity 23 and the second adjusting cavity 24 without considering the adjusting pieces, the arrangement connection line between the first port 21 and the second port 22 is parallel to the partition plate 27, and the first port 21 and the second port 22 cross the partition plate 27 upward and downward, so that the upper region of the first port 21 and the second port 22 is communicated with the first adjusting cavity 23, and the lower region is communicated with the second adjusting cavity 24, so as to realize the requirement that the first port 21 and the second port 22 can be communicated with the fresh air outlet 12 and the exhaust air inlet 13 as needed. The first adjusting piece 25 and the second adjusting piece 26 are both arranged perpendicular to the partition plate 27, and the movement track lines of the two are parallel to the partition plate 27, and move along the arrangement connection line of the first port 21 and the second port 22.

[0044] Of course, the specific structure of the adjusting assembly 20 is not limited to the above-mentioned manner of the embodiment, and according to different settings of the fresh air outlet 12 and the exhaust air inlet 13, the shape of the shell 10, and other factors, the shape of the shell 28, the separation manner of the partition 27, the movement manner of the first adjusting piece 25 and the second adjusting piece 26, and the like can be adjusted as needed, as long as they are adapted to the fresh air unit 30 and the exhaust air unit 40 and can realize the switching of the functions of the first port 21 and the second port 22.

[0045] Alternatively, the connection manner between the shell 28 and the shell 10 can also be set as needed, and the two can adopt a split structure, a subsequent connection assembly manner, or an integrated molding manner.

[0046] In the embodiment, in addition to realizing different functions respectively, the first port 21 and the second port 22 can also realize the same function at the same time. Specifically, the fresh air unit 30 and the exhaust air unit 40 of the embodiment can be independently operated, that is, the fresh air unit 30 and the exhaust air unit 40 can be started and stopped as needed. At the same time, the first adjusting plate also has a fifth position, when the first adjusting plate is located at the fifth position, the fresh air outlet 12, the first port 21 and the second port 22 are located in the same sub-cavity, at this time the fresh air outlet 12 is in communication with the first port 21 and the second port 22 at the same time, and the first port 21 and the second port 22 can simultaneously function as the outlet of fresh air. Similarly, the second adjusting plate also has a sixth position, when the second adjusting plate is located at the sixth position, the exhaust air inlet 13, the first port 21 and the second port 22 are located in the same sub-cavity, at this time the exhaust air inlet 13 is in communication with the first port 21 and the second port 22 at the same time, and the first port 21 and the second port 22 can simultaneously function as the inlet of exhaust air. In this way, when the first adjusting plate is located at the fifth position, the second adjusting plate is located at the third position or the fourth position, and the fresh air unit 30 works while the exhaust air unit 40 stops, the fresh air unit 30 passes through the first port 21 and the second port 22 to fully pass in fresh air, so that the fresh air unit is in a whole house positive pressure fresh air mode; and when the second adjusting plate is located at the sixth position, the first adjusting plate is located at the first position or the second position, and the exhaust air unit 40 works while the fresh air unit 30 stops, the exhaust air unit 40 passes through the first port 21 and the second port 22 to fully exhaust air, so that the fresh air unit is in a whole house negative pressure exhaust air mode.

[0048] Specifically, the working modes in the embodiment are divided into four modes, including a left air supply mode, a right air supply mode, a positive pressure fresh air mode and a negative pressure exhaust air mode. In the left air supply mode, the first adjusting plate is located at the first position, the second adjusting plate is located at the third position, the fresh air outlet 12 is only communicated with the first port 21 through the communication cavity, and the exhaust air inlet 13 is only communicated with the second port 22 through the communication cavity. In the right air supply mode, the first adjusting plate is located at the second position, the second adjusting plate is located at the fourth position, the fresh air outlet 12 is only communicated with the second port 22 through the communication cavity, and the exhaust air inlet 13 is only communicated with the first port 21 through the communication cavity. In the above left air supply mode and right air supply mode, the fresh air unit 30 and the exhaust air unit 40 are started at the same time, and the fresh air machine is in a full heat exchange mode. In the positive pressure fresh air mode, the first adjusting plate is located at the fifth position, the second adjusting plate is located at the third position or the fourth position, and the fresh air unit 30 is started while the exhaust air unit 40 is stopped, and the fresh air outlet 12 is communicated with the first port 21 and the second port 22 through the communication cavity. In the negative pressure exhaust air mode, the second adjusting plate is located at the sixth position, the first adjusting plate is located at the first position or the second position, and the exhaust air unit 40 is started while the fresh air unit 30 is stopped, and the exhaust air inlet 13 is communicated with the first port 21 and the second port 22 through the communication cavity. Of course, the working mode can also be adjusted as needed, and only the left air supply mode and the right air supply mode can be set, or more working modes can be set as needed.

[0049] In the embodiment, the fresh air machine further comprises a damper, and dampers are arranged at the fresh air inlet 11 and the exhaust air outlet 14, and the dampers are used to open or close the fresh air inlet 11 and the exhaust air outlet 14.
