[0033] The following is a further detailed description of the implementation of the present application in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application but cannot be used to limit the scope of the present application.

[0034] The various specific technical features and embodiments described in the specific implementation methods can be combined in any suitable manner without contradiction. For example, different implementation methods can be formed by combining different specific technical features / embodiments. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features / embodiments in this application are no longer described separately. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. The application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] It should be noted that, in the present application, down refers to the direction toward the ground, and up refers to the direction opposite to down. The first direction, the second direction and the third direction form a three-dimensional vertical coordinate system that is perpendicular to each other.

[0036] See also Figures 1 to 4In a first aspect, an embodiment of the present application provides a shell assembly 100 of a fresh air device 1000, including a shell 10 and a partition 20. The shell 10 includes a shell body 11. The shell body 11 has a bottom plate 111 and a plurality of side panels 112. The plurality of side panels 112 are all arranged on the same side in the thickness direction of the bottom plate 111. The partition 20 is arranged in the shell body 11. The partition 20 defines a heat exchange chamber 10a and a fan chamber 10b in the space in the shell body 10. The shell body 11 and the partition 20 are both integrally formed structures.

[0037] The heat exchange chamber 10a is used to place the heat exchange core 200, which is used to perform heat exchange between the indoor airflow and the outdoor airflow. The fan chamber 10b is used to place the fan assembly, which is used to drive the indoor airflow and / or the outdoor airflow to flow.

[0038] For example, see Figure 1 , the heat exchange core 200 extends along the second direction, the fan chamber 10b is located on one side of the heat exchange chamber 10a along the second direction, and the space in the housing 10 is divided by the partition 20 to limit the flow direction of the airflow in the housing 10. The fan chamber 10b and the heat exchange core 200 are roughly T-shaped, so that the air flow in the housing 10 is smoother, achieving the effects of large air volume, low energy consumption and quietness.

[0039] For example, see Figure 2 A plurality of side panels 112 are disposed on one side of the chassis 111 along the third direction to define a space for accommodating the partition 20 , and at least a portion of the partition 20 is connected to the housing 10 , thereby enhancing the connection stability between the housing 10 and the partition 20 .

[0040] The shell assembly 100 provided in the embodiment of the present application, the shell 11 and the partition 20 are all integrally formed structures. The shell 11 and the partition 20 can reduce the use of seals and fasteners, improve the sealing and structural stability of both the shell 11 and the partition 20, and enhance the reliability of the fresh air device 1000; it also reduces the assembly steps of both the shell 11 and the partition 20, thereby reducing the error rate and improving production efficiency.

[0041] A second aspect of the embodiments of the present application provides a fresh air device 1000, comprising a housing assembly 100 and a heat exchange core 200 in any one of the embodiments of the present application, wherein the heat exchange core 200 is disposed in a heat exchange cavity 10a.

[0042] The heat exchange core 200 is used to exchange heat between indoor airflow and outdoor airflow, which can improve heat exchange efficiency and reduce energy consumption. For example, the outdoor airflow with a higher temperature and the indoor airflow with a lower temperature exchange heat in the heat exchange core 200, and the indoor airflow can absorb the heat in the outdoor airflow, and send the comfortable outdoor airflow into the room, changing the temperature and / or humidity of the indoor environment and improving the user experience.

[0043] The fresh air device 1000 provided in the embodiment of the present application, the heat exchange chamber 10a provides a space for accommodating the heat exchange core 200, and the shell 11 and the partition 20 are both integrally formed structures, which facilitates the assembly of the heat exchange core 200 into the placement space 10c, reduces the difficulty of assembly, improves the assembly efficiency of the fresh air device 1000, and also improves the assembly quality of the fresh air device 1000.

[0044] The fresh air device 1000 provided in the embodiment of the present application can be installed on the ceiling or the ceiling panel. The ceiling panel can separate the indoor space into the ceiling space and the living space. Users carry out their daily lives in the living space, and the ceiling space is not only used to beautify the interior decoration, but also to install other equipment. In one embodiment, the fresh air device 1000 is arranged in the ceiling space. In this way, the fresh air device 1000 is hidden in the ceiling space, avoiding the user from directly observing the entire fresh air device 1000, thereby improving the visual aesthetics. It can be understood that the indoor space includes but is not limited to balconies, bathrooms, kitchens, etc., and can be a large-sized house, a small-sized house, or other types of production or living environments.

[0045] When the fresh air device 1000 provided in the embodiment of the present application is mounted on a ceiling or a ceiling plate, the third direction is consistent with the up-down direction. Taking the case that the housing 10 is roughly hexahedral as an example, the third direction may be the thickness direction of the chassis 111. Taking the case that the fresh air device 1000 is mounted in a ceiling space as an example, the thickness direction of the chassis 111 is along the up-down direction, which facilitates the assembly of the fresh air device 1000 into the ceiling space.

[0046] In some embodiments, the housing 10 includes a cover plate, and the three side plates 112 are sequentially connected along the circumference of the bottom plate 111 , and the cover plate connects two opposite side plates 112 .

[0047] For example, see Figure 2 , the three side panels 112 and the bottom plate 111 jointly define a placement space 10c, wherein the two opposite side panels 112 define an assembly port 10d, and the cover plate connects the two opposite side panels 112 to shield the assembly port 10d. In this way, on the one hand, the parts of the fresh air device 1000, such as the partition 20, can first enter the placement space 10c through the assembly port 10d, thereby reducing the error rate and improving the assembly efficiency. On the other hand, the cover plate shields the assembly port 10d, which can prevent foreign debris from easily entering the placement space 10c and causing damage to the parts. The parts are hidden in the placement space 10c, and the outer shell 10 has a better aesthetic appearance.

[0048] In some embodiments, the housing 10 includes a cover 12, which is disposed on a side of the side plate 112 away from the bottom plate 111. Figure 3The placement space 10c is formed with an opening 10d1 along the third direction, and the cover body 12 covers the opening 10d1. In this way, the outer shell 10 is relatively closed as a whole, which can effectively prevent external water and / or impurities from entering the placement space 10c to cause damage to components, thereby improving the safety of the fresh air equipment 1000.

[0049] For example, the fresh air device 1000 is set on the ceiling, and the opening 10d1 faces downward, and the operator needs to work below the fresh air device 1000. The second opening 10d1 of the cover body 12 prevents the parts of the fresh air device 1000 from loosening and falling out through the opening 10d1 during assembly, thereby reducing safety risks.

[0050] For some examples, see Figure 1 and Figure 4 The housing assembly 100 includes a first fastener 30 and a fan housing 40 located in the housing 11, and the first fastener 30 is penetrated to the fan housing 40 and the chassis 111 along the thickness direction of the chassis 111. In other words, the first fastener 30 is penetrated to the fan housing 40 and the chassis 111 along the third direction. Exemplarily, during the assembly process, the first fastener 30 can be penetrated to the fan housing 40 and the chassis 111 from top to bottom, which is simple to operate and improves assembly efficiency.

[0051] The first fastener 30 includes, but is not limited to, a screw and the like.

[0052] The fan housing 40 plays a role of guiding air. In one embodiment, the fan housing 40 can be a volute.

[0053] In some embodiments, the housing assembly 100 includes a bracket 50, which is located in the housing 11 and connected to the chassis 111. The fan housing 40 is formed with a support foot 41, which is supported by the bracket 50. The first fastener 30 is penetrated to the support foot 41 and the bracket 50 along the thickness direction of the chassis 111. The bracket 50 can enhance the stability of the fan housing 40. For example, please refer to Figure 4 , taking the plane perpendicular to the third direction as the projection plane, the projection of the support foot 41 is located outside the projection of the fan casing 40. In this way, the visual effect is good, which facilitates the first fastener 30 to fix the fan casing 40 and the bracket 50, thereby improving the assembly efficiency.

[0054] In one embodiment, the bracket 50 may be a sheet metal part with low cost and high structural strength.

[0055] For some examples, see Figure 1There are three side panels 112, and the two side panels 112 opposite to each other along the first direction are respectively the first side panel 1121 and the second side panel 1122. The first side panel 1121 is formed with an air supply port 1121a and a return air port 1121b, and the second side panel 1122 is formed with an air exhaust port 1122a and a fresh air port 1122b. The return air port 1121b and the fresh air port 1122b are respectively located on both sides of the heat exchange chamber 10a along the first direction, and the air supply port 1121a and the air exhaust port 1122a are respectively located on both sides of the fan chamber 10b along the first direction.

[0056] The fresh air inlet 1122b is used to introduce outdoor airflow into the housing 10, and the return air inlet 1121b is used to introduce indoor airflow into the housing 10. The air supply outlet 1121a is used to discharge the outdoor airflow in the housing 10 out of the housing 10. The exhaust air outlet 1122a is used to discharge the indoor airflow in the housing 10 out of the housing 10. Exemplarily, the outdoor airflow enters the room through the fresh air inlet 1122b, the heat exchange chamber 10a and the air supply outlet 1121a in sequence; the indoor airflow is discharged to the outside through the return air inlet 1121b, the heat exchange chamber 10a and the exhaust air outlet 1122a in sequence. The outdoor airflow and the indoor airflow realize heat exchange at the heat exchange core 200.

[0057] For example, see Figure 1 , the fresh air inlet 1122b and the return air inlet 1121b are located on both sides of the heat exchange chamber 10a along the first direction, and the air supply inlet 1121a and the exhaust air inlet 1122a are located on both sides of the fan chamber 10b along the first direction. On the one hand, it is convenient for the return air inlet 1121b, the air supply inlet 1121a, the fresh air inlet 1122b and the exhaust air inlet 1122a to be externally connected to the air duct, avoiding interference between the air duct and the ceiling plate and the ceiling, and also avoiding the problem of over-size caused by forming the above-mentioned air inlets on more than two side walls of the housing 10; on the other hand, the indoor airflow and the outdoor airflow flow smoothly in the housing 10, which can reduce eddy currents.

[0058] For some examples, see Figure 2 and Figure 3 The partition 20 includes a partition plate 21 and a receiving frame 22. The receiving frame 22 is formed with a receiving chamber 22a which opens in a direction away from the bottom plate 111. The receiving chamber 22a is used to receive the heat exchange core 200. The partition plate 21 connects the receiving frame 22 and one of the side plates 112. In this way, the heat exchange core 200 enters and exits the receiving chamber 22a through the opening, which is convenient for operation.

[0059] Taking the installation of the fresh air device 1000 on the ceiling as an example, at this time, the opening of the storage bin 22a faces downward, which is convenient for operators to disassemble and assemble the heat exchange core 200 and to inspect and repair the heat exchange core 200.

[0060] For example, see Figure 2The partition plate 21 connects the containing frame 22 and the first side plate 1121, that is, the partition plate 21 connects the surrounding part of the return air port 1121b. On the one hand, the indoor air flow can flow along the surface of the partition plate 21, and the partition plate 21 plays a guiding role, which can reduce the resistance of the indoor air flow and reduce noise. On the other hand, the stability of the containing frame 22 can be improved, thereby enhancing the stability of the heat exchange core 200.

[0061] In some embodiments, the partition 20 includes an isolation plate 23 , which is located on a side of the receiving frame 22 away from the isolation plate 21 , and the isolation plate 23 connects the other side plate 112 and the receiving frame 22 .

[0062] For example, see Figure 2 and Figure 3 The isolation plate 23 connects the containing frame 22 and the second side plate 1122, that is, the isolation plate 23 connects the surrounding area of ​​the fresh air outlet 1122b. On the one hand, the outdoor air flow can flow along the surface of the isolation plate 23, and the isolation plate 23 plays a guiding role, which can reduce the resistance of the outdoor air flow and reduce noise. On the other hand, the stability of the containing frame 22 can be improved, thereby enhancing the stability of the heat exchange core 200.

[0063] For some examples, see Figure 2 The receiving frame 22 includes a support seat 221 and two frames 222, the frames 222 are formed with vents 222a, the support seat 221 is arranged on the chassis 111, and the two frames 222 are connected to the two opposite sides of the support seat 221 to jointly define the receiving chamber 22a. The support seat 221 is used to enhance the connection stability of the frames 222. The airflow can enter the receiving chamber 22a through the vents 222a, so that the indoor airflow and the outdoor airflow can flow to the heat exchange core 200 through the vents 222a to achieve heat exchange.

[0064] Taking the heat exchange core 200 as an example, which is roughly hexahedral, for example, please refer to Figure 2 and Figure 3 The two frames 222 are connected to the opposite sides of the support base 221 along the first direction, and the two frames 222 form an angle with the bottom plate 111, that is, the heat exchange core 200 is tilted relative to the bottom plate 111. In this way, the contact area between the heat exchange core 200 and the airflow can be increased, and the heat exchange efficiency of the fresh air device 1000 can be improved.
