For example, ventilation equipment has been widely used in recent years. Ventilation equipment introduces fresh outdoor air, improving indoor air quality and enhancing user comfort.

[0003] In some air handling devices, for example, inside a housing of a ventilation device, an electrical component box for accommodating electrical components is provided.

[0004] It should be noted that the above technical background is merely for the purpose of providing a clear and complete description of the technical solutions of the present invention and to facilitate understanding by those skilled in the art. It should not be assumed that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of the present invention. Utility Model Content

[0005] Currently, the heat dissipation requirements of electrical component boxes installed inside air handling equipment are not considered, which may lead to poor heat dissipation of the electrical component box and the electrical components inside, affecting the electrical safety and performance of the electrical components and even the entire air handling equipment;

[0012] In some embodiments, the air treatment device further includes: a snap-fit portion, which is disposed in the housing and snap-fits with the electrical component box.

[0013] In some embodiments, the engaging portion contacts a partial area of the box cover of the electrical component box, and the opening is provided at a position outside the partial area on the box cover.

[0014] In some embodiments, the electrical component includes a heating element, and the heating element is disposed at a position corresponding to the opening.

In the height direction of the shell, the limiting portion is arranged between the electrical component box and the top plate of the shell, or the limiting portion is arranged between the electrical component box and the bottom plate of the shell.

[0016] In some embodiments, the limiting portion is provided at a corner portion inside the housing.

[0017] In some embodiments, the box body of the electrical component box is provided with a hole on a side away from the return air outlet.

[0018] In some embodiments, the electrical component box is connected to the side wall of the housing through a fixing component, and a gap is provided between the electrical component box and the side wall.

[0019] In some embodiments, the box body of the electrical component box has a protrusion protruding toward the outside of the box body.

[0020] In some embodiments, a plurality of openings are provided on the box cover of the electrical component box, each opening is in the shape of an elongated strip, and the baffle is provided on at least one long side of the opening.

[0021] In some embodiments, the baffle is a straight plate or a curved plate.

[0022] In some embodiments, the air handling device further includes a heat exchange core, an air supply fan, and an air exhaust fan disposed in the housing.

[0023] In some embodiments, the air supply fan is arranged near the air supply port, and the air exhaust fan is arranged near the air exhaust port.

[0024] One of the beneficial effects of the embodiment of the utility model is:

[0025] By providing an opening on the cover of the electrical component box relatively close to the return air outlet, the hot air flow caused by the heating of the electrical components in the electrical component box can be discharged through the opening and discharged to the outside of the air handling device along with the return air flow, thereby improving the heat dissipation effect of the electrical components in the electrical component box and ensuring the electrical safety and performance of the air handling device;

[0026] In addition, by providing a baffle extending toward the outside of the electrical component box at the edge of the opening on the upstream side of the airflow direction, on the one hand, it can prevent condensed water or dust and particulate matter inside the air handling equipment from entering the interior of the electrical component box and causing electrical safety problems; on the other hand, it can guide the direction of the return air flow and further improve the heat dissipation effect.

[0027] Furthermore, the opening extends along the height of the housing, and the baffle is disposed on a side of the opening proximal to the return air vent and extends away from the return air vent, thereby further preventing condensed water, dust, and particulate matter from entering the interior of the electrical component box and better directing the return airflow, thereby improving heat dissipation. Furthermore, in the height direction, regardless of whether the air handling device is installed in a forward or reverse orientation, the baffle effectively prevents condensed water, dust, and particulate matter from entering the interior of the electrical component box and better directs the return airflow, thereby improving heat dissipation.

[0028] Furthermore, the opening extends in a direction parallel to the bottom plate of the shell, and the baffle is arranged on the edge of the upper side of the opening and extends toward the bottom plate of the shell, thereby further preventing condensed water or dust and particulate matter from entering the interior of the electrical component box and better guiding the return air flow to improve the heat dissipation effect.

[0029] Furthermore, the electrical component box is arranged in the corner of the shell near the return air outlet. In this way, other components inside the air treatment equipment can be reasonably arranged. By setting the electrical component box in the area with less airflow such as the corner, the impact on the air flow inside the air treatment equipment can be reduced, the pressure loss of the whole machine can be reduced, and it is conducive to the miniaturization of the whole machine.

[0030] Furthermore, by providing the engaging portion, the use of fixing components can be reduced, making it easier to disassemble, assemble and repair the electrical component box.

[0031] Furthermore, by providing a limit portion, the electrical component box can be prevented from moving in the height direction in various installation and maintenance scenarios and during use, thereby ensuring the stability of the equipment operation.

[0032] Furthermore, the limiting portion is disposed at a corner within the housing, thereby reducing the impact on airflow and heat dissipation within the air handling device. Alternatively, for example, the limiting portion is disposed at a position corresponding to the engaging portion, where no fastening mechanism is provided. The limiting portion and the engaging portion can be used to engage and secure the electrical component box.

[0033] Furthermore, the box body of the electrical component box is provided with a hole on the side away from the return air outlet, so that the wires can be passed through and arranged conveniently. In addition, the hot air flow in the electrical component box can be discharged through the hole and discharged to the outside of the equipment along with the return air flow, thereby further improving the heat dissipation effect.

[0034] Furthermore, there is a gap between the electrical component box and the side wall that fixes the electrical component box. In this way, the space formed by the gap can accommodate the protruding parts of certain components in the electrical component box (such as circuit board fixing buckles, ends of fixing screws, etc.), and can also form a heat dissipation space to further improve the heat dissipation effect.

[0035] Furthermore, the housing of the electrical component box has a protrusion that projects outward from the housing. This creates a space that can accommodate the protruding portions of certain components within the electrical component box and also creates a heat dissipation space, further enhancing heat dissipation. This also facilitates miniaturization of the electrical component box. For example, the protrusion can be positioned away from the engaging portion.

[0036] Furthermore, a plurality of such openings are provided on the cover of the electrical component box, and the openings are in the shape of long strips, and the baffle is provided on at least one long side of the opening. In this way, the cover structure is simple, which can further improve the heat dissipation effect of the opening, and further improve the effect of the baffle in preventing condensed water, dust, particulate matter, etc. from entering the interior of the electrical component box and guiding the return air flow.

[0037] Furthermore, the baffle is straight or curved, so that it can be freely designed according to actual conditions, improving manufacturing efficiency and further improving the baffle's ability to prevent condensed water, dust, particulate matter, etc. from entering the interior of the electrical component box and to guide the return air flow.

[0054] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

[0055] An embodiment of the utility model provides an air treatment device.

[0056] In some embodiments, the air handling device is a ventilation device, such as a ventilation device having a heat exchange unit. The internal structure of the air handling device is described below using a ventilation device as an example. However, embodiments of the present invention may also be applied to other air handling devices besides ventilation devices.

[0057] Figure 1 This is a top view of an embodiment of the internal structure of the air handling equipment of the utility model. Figure 1 The internal structure of the air handling equipment is shown with the top of the air handling equipment omitted.

[0058] In the embodiment of the present utility model Figure 1 In other figures, the x direction represents the length direction of the air handling device, the y direction represents the width direction of the air handling device, and the z direction represents the height direction of the air handling device. Figure 1 As shown, the air handling device 100 includes a shell 110 and an electrical component box 120 arranged in the shell 110. The shell 110 has a side wall 111, and a fresh air inlet 113, an air supply outlet 114, a return air inlet 115 and an exhaust outlet 116 are arranged on the side wall 111 of the shell 110.

[0059] In some embodiments, the housing 110 further comprises a bottom plate 112, a top plate ( Figure 1 (not shown). Thus, the bottom plate, top plate, and side walls form a closed space within the housing 110. The space within the housing 110 includes a fresh air chamber A connected to the fresh air inlet 113, a supply air chamber B connected to the supply air outlet 114, a return air chamber C connected to the return air outlet 115, and an exhaust air chamber D connected to the exhaust outlet 116.

[0060] In some embodiments, the air treatment device 100 has an external circulation mode and an internal circulation mode.

[0061] When the air handling device 100 is in the external circulation mode, Figure 1 As shown by the dotted arrow in the figure, an air supply path is formed between the fresh air inlet 113 and the air supply outlet 114, through which the fresh air flow is introduced into the room; an exhaust path is formed between the return air inlet 115 and the exhaust outlet 116, through which the return air flow is discharged outdoors;

[0062] When the air handling device 100 is in the internal circulation mode, Figure 1 As shown by the dotted arrow in FIG, an internal circulation path is formed between the return air port 115 and the exhaust air port 114, and the indoor air flow circulates through the internal circulation path.

[0063] in addition, Figure 1 The dotted arrows in the figure schematically represent the above paths, but are not intended to limit the relevant paths.

[0064] In some embodiments, as Figure 1 As shown, the air treatment device 100 may also include a supply fan 131 and an exhaust fan 132 arranged in the shell. The supply fan 131 is used to form an air flow and introduce fresh air from the outside through the fresh air inlet 113, or introduce return air from the room through the return air inlet 115. The exhaust fan 132 is used to form an air flow and exhaust air to the outside.

[0065] In addition, if Figure 1As shown, the air supply fan 131 is arranged near the air supply port 114 , and the air exhaust fan 132 is arranged near the air exhaust port 116 .

[0066] In some embodiments, as Figure 1 As shown, the air treatment device 100 may further include a heat-insulating cavity (or inner shell) disposed inside the shell, and a partition member, such as a first partition member 161 and a second partition member 162, is disposed inside the heat-insulating cavity to isolate airflows in different paths within the shell 110. For example, the partition member (such as the first partition member 161 and the second partition member 162) may be integrally formed with the heat-insulating cavity.

[0067] For example, a wire groove may be formed on the partition member (eg, the first partition member 161 and the second partition member 162 ), or sheet metal may be embedded in the wall surface of the heat insulation cavity to fix the wire buckle.

[0068] Alternatively, the heat insulating cavity may not be provided, and sealing and heat insulation may be achieved by applying elastic or soft materials to the inner surface of the shell and the surfaces of the partition members (such as the first partition member 161 and the second partition member 162).

[0069] In some embodiments, as Figure 1 As shown, the air treatment device 100 may further include a heat exchange unit 140 disposed in the housing, for performing heat exchange on the air passing through the heat exchange unit 140 , for example, heating the air passing through the heat exchange unit 140 .

[0070] For example, the heat exchange element 140 is a heat exchange core, and the heat exchange core and the partition component together define the supply air path and the exhaust air path. The heat exchange core is formed by a plurality of stacked heat exchange elements. Adjacent heat exchange elements are respectively connected to the supply air path and the exhaust air path. When the fresh air and the indoor return air pass through the adjacent heat exchange elements, they exchange heat or moisture through heat exchange sheets (such as paper, moisture-permeable membrane, etc.).

[0071] For example, the heat exchange unit 140 is disposed in the shell through a supporting component, and the supporting component is sealed and connected to the partition component to improve the sealing performance to ensure that the air flow in the supply air path and the exhaust air path does not cross flow.

[0072] For example, the supporting component may be directly fixed to the shell, or the supporting component may be fixed by pre-embedding a sheet metal part on the partition component.

[0073] For example, the support component may be provided with a guide rail that engages with the heat exchange core, and may also be integrally formed with a filter slot to facilitate the installation of a filter near the heat exchange core.

[0074] Specifically, such as Figure 1As shown, primary filters are respectively provided on the side of the heat exchange core close to the fresh air inlet and the side close to the return air inlet. The primary filters are fixed by the filter slots on the supporting components. The structure is simple and easy to install and maintain.

[0075] like Figure 1 As shown, the air treatment device 100 further includes a filter 170 disposed on the side of the heat exchange core close to the air outlet. The filter can be any one of a PM2.5 filter, an activated carbon filter, an electrostatic dust collection filter, and a formaldehyde removal filter. The filter can be as follows: Figure 1 The air supply fan is shown to form a semi-enclosed L-shape, or a straight-line shape. Setting the filter in this way can ensure the cleanliness of the air sent into the room, and can reasonably utilize the internal space of the equipment, which is conducive to miniaturization.

[0076] like Figure 1 As shown, on the air supply path, filters are respectively provided upstream and downstream of the heat exchange core. The filters can also be integrated and provided on the upstream or downstream side of the heat exchange core to facilitate installation and maintenance.

[0077] In some embodiments, as Figure 1 As shown, the air treatment equipment 100 may also include a first air valve assembly 151, a second air valve assembly 152 and an air valve bracket 153, wherein the first air valve assembly 151 is arranged between the return air outlet 115 and the supply air outlet 114, and is used to open or close the internal circulation path, the first air valve assembly 151 has a frame, a first valve plate is provided in the frame, a first opening is formed on the frame, and a second opening is formed on the air valve bracket 153, the first valve plate can be switched between the first opening and the second opening, and is used to close or open the first opening (forming an internal circulation path) or the second opening (forming an exhaust path); in addition, the second air valve assembly 152 is arranged on the inner side of the fresh air outlet, and the second air valve assembly 152 includes a second valve plate, and the second valve plate is used to close or open the fresh air outlet 113.

[0078] like Figure 1 As shown, the first air valve assembly 151 and the second air valve assembly 152 are both driven by motors, such as DC motors, which can not only adjust the opening and closing of the air valve assembly, but also adjust the opening degree of the air valve assembly, with a high degree of automation.

[0079] In some embodiments, as Figure 1 and Figure 3As shown, the air treatment device 100 may also include a first sensor component 181 and a second sensor component 182. For example, the first sensor component 181 and the second sensor component 182 include at least two of a temperature sensor, a humidity sensor, a CO2 sensor, an odor sensor, a TVOC sensor and a PM2.5 sensor. The first sensor component 181 detects the temperature, humidity and air quality of the air on the supply path, such as the concentration of particulate matter, and the second sensor component 182 detects the temperature, humidity and air quality of the air on the exhaust path, such as the concentration of particulate matter.

[0080] The above passed Figure 1 The internal structure of the air treatment device 100 is described as an example. However, the air treatment device 100 may not include all of the above components, or may also include Figure 1 Parts not shown in FIG.

[0081] In some embodiments, the electrical component box 120 contains electrical components, which can be at least one electrical component used to control or drive components within the air treatment device 100. For example, the electrical components contained in the electrical component box 120 include but are not limited to a control circuit board. In addition, two driving parts for driving the motor in the supply fan 131 and the motor in the exhaust fan 132, respectively, can be provided on the control circuit board.

[0082] Figure 2 It is a top view of another embodiment of the internal structure of the air treatment equipment of the embodiment of the present utility model.

[0083] like Figure 2 As shown, in the air handling device 100', the first air valve assembly 151 is arranged between the return air inlet 115 and the fresh air inlet 113, and is used to open or close the internal circulation path (such as Figure 2 (As indicated by the dotted arrow), the first air valve assembly 151 has a frame, a first valve plate is provided in the frame, an opening is formed on the frame, the first valve plate is used to close or open the opening, and when the opening is opened, an internal circulation path is formed, and the internal circulation air flow passes through the heat exchange unit 140 (such as a heat exchange core) and then is sent into the room from the air supply port 114; in addition, the second air valve assembly 152 is provided outside the fresh air port, and the second air valve assembly 152 includes a second valve plate, and the second valve plate is used to close or open the fresh air port 113. In addition, as Figure 2 As shown by the dotted arrow in the figure, an air supply path is formed between the fresh air inlet 113 and the air supply outlet 114, passing through the heat exchange unit 140 (for example, a heat exchange core), and the fresh air flow is introduced into the room through the air supply path; an exhaust path is formed between the return air inlet 115 and the exhaust air outlet 116, passing through the heat exchange unit 140 (for example, a heat exchange core), and the return air flow is discharged outdoors through the exhaust path.

[0084] In addition, if Figure 2 As shown, an integrated filter 171 is provided on one side of the heat exchange unit 140 (eg, heat exchange core) close to the fresh air inlet 113 , and a primary filter 172 is provided on one side of the heat exchange unit 140 (eg, heat exchange core) close to the air supply outlet 114 .

[0085] Figure 2 For other components, please refer to Figure 1 In addition, the air treatment equipment 100' may not include all of the above components, or may also include Figure 2 Parts not shown in FIG.

[0086] Figure 3 It is a top view from another perspective of an implementation method of the internal structure of the air treatment equipment of an embodiment of the present utility model. Figure 3 The structure shown is Figure 1 For specific parts, please refer to the above Figure 1 The description is not repeated here.

[0087] like Figure 1 and Figure 3 As shown, the electrical component box 120 is disposed within the return air cavity, i.e., within the housing 110 near the return air inlet 115. Specifically, the electrical component box 120 is disposed adjacent to the return air inlet 115, for example, within the housing 110 near a corner of the return air inlet 115. This allows for a rational layout of other components within the air handling device 100. By utilizing the corner, an area with less airflow, such as the electrical component box, the impact on the airflow within the air handling device 100 can be reduced, lowering the overall pressure loss and facilitating overall miniaturization.

[0088] Figure 4 yes Figure 3 An enlarged view of part of the structure including the electrical component box.

[0089] like Figure 4 、 Figure 3 as well as Figure 1 As shown, the length direction of the electrical component box 120 is the x direction, the width direction of the electrical component box 120 is the z direction, and the thickness (height) direction of the electrical component box 120 is the y direction. The width of the electrical component box 120 is smaller than the height of the housing of the air handling device.

[0090] like Figure 4 and Figure 3As shown, the electrical component box 120 includes a box body 121 and a box cover 122. The box cover 122 is closer to the return air inlet 115 than the box body 121. For example, in the thickness (height) direction (y direction) of the electrical component box 120, the box cover 122 is closer to the return air inlet 115 than the box body 121. The back side of the box body 121 of the electrical component box 120 is opposite to the side wall 111.

[0091] like Figure 4 As shown, the box cover 122 is provided with at least one opening 123, and a baffle 124 is provided on the edge of the opening 123 on the upstream side in the airflow direction, extending toward the outside of the electrical component box. The airflow direction is the direction of the return air flow, and the upstream side in the airflow direction is the side close to the return air outlet.

[0092] In this way, the hot air flow caused by the heating of the electrical components in the electrical component box can be discharged to the outside of the electrical component box through the opening 123 and discharged along with the return air flow (combined with the return air flow). Figure 1 The heat is discharged to the outside of the air handling equipment (as shown), thereby improving the heat dissipation effect of the electrical component box and the electrical components inside it, and ensuring the electrical safety and performance of the electrical components and the entire air handling equipment; in addition, by providing a baffle 124 extending to the outside of the electrical component box at the edge of the opening 123 on the upstream side of the airflow direction (the side close to the return air outlet), on the one hand, it can prevent condensed water, dust, particulate matter, etc. inside the air handling equipment from entering the interior of the electrical component box and causing electrical safety problems, and on the other hand, it can guide the flow direction of the return air flow to further improve the heat dissipation effect.

[0093] Moreover, the heat of the return air flowing to the heat exchange core can also be exchanged with the air flow introduced from the fresh air inlet, thereby improving the heat exchange efficiency.

[0094] In some embodiments, the number of openings 123 provided on the box cover 122 may be one or more. The specific number of the openings 123 may be designed according to actual conditions, and the embodiment of the present invention is not limited thereto.

[0095] In some embodiments, the opening 123 can extend along the height direction of the shell 110 (i.e., the width direction of the electrical component box), that is, it can be set vertically; it can also extend in a direction parallel to the base plate 112 (i.e., the length direction of the electrical component box), that is, it can be set horizontally; or it can also extend in other opposite directions different from the width direction and the length direction, such as being set obliquely or curved.

[0096] In addition, the extension directions of the plurality of openings 123 may be the same or different, that is, the plurality of openings 123 may be arranged parallel to each other or not. The embodiment of the present invention does not limit the extension direction of the openings 123.

[0097] In some embodiments, the size of the opening 123 can be designed according to actual conditions, and the embodiment of the present invention does not limit the size of the opening 123 .

[0098] In some embodiments, the shape of the opening 123 can be designed according to actual conditions. For example, the opening 123 is in the shape of a strip, an arc, or a circle.

[0099] In some embodiments, a baffle 124 can be set on the edge of all openings 123 on the upstream side of the airflow direction (the side close to the return air outlet), or a baffle 124 can be set on the edge of some openings 123 on the upstream side of the airflow direction (the side close to the return air outlet).

[0100] For example, a baffle 124 is set at the edge of the upstream side of the multiple long strip openings 123 in the airflow direction. In this way, the box cover structure is simple, which can further improve the heat dissipation effect of the opening and further improve the effect of the baffle in preventing condensed water or dust and particulate matter from entering the interior of the electrical component box and guiding the flow direction of the return air flow.

[0101] In some embodiments, the baffle 124 can be a straight plate or a curved plate.

[0102] For example, the baffle 124 is a straight plate and is tilted relative to the cover 122 in a direction away from the return air outlet 115 (e.g., the positive direction of the x-axis). The angle between the baffle 124 and the cover 122 is a preset angle that is less than 90 degrees. This not only better prevents condensation, dust, and particulate matter from entering the box body, but also prevents the hot air flowing out of the opening from directly colliding with the return air flow, forming turbulent flow, thereby facilitating smooth mixing of the hot air flow and the return air flow. In some embodiments, the baffle 124 can be formed by folding the sheet metal of the cover 122.

[0103] In some embodiments, the projection of the baffle 124 may cover the entire opening 123 (see, for example, Figure 4 ), or, alternatively, a portion of the opening 123 may be covered (see, for example, Figure 2 ).

[0104] The following is an exemplary description of the structure of the opening and the baffle on the electrical component box according to the embodiment of the present invention.

[0105] Figure 5 This is a three-dimensional diagram of an embodiment of an electrical component box according to the present invention; Figure 6 yes Figure 5 A perspective view of a portion of the structure in the electrical component box shown in another perspective; Figure 7 This is a three-dimensional diagram of an implementation manner of the electrical component box according to an embodiment of the present invention from another perspective.

[0106] like Figure 5 、 Figure 6 and Figure 7 As shown, the opening 123 extends along the height direction of the housing 110 (ie, the width direction of the electrical component box 120, the z direction), that is, after the electrical box 120 is installed inside the housing 110, the opening 123 extends along the height direction of the housing 110 (combined with the width direction of the electrical component box 120, the z direction). Figure 1 and Figure 3 shown).

[0107] Combine Figures 4 to 7 As shown, baffle 124 is positioned at the edge of opening 123 upstream in the airflow direction (on the side closer to return air port 115), and baffle 124 extends away from return air port 115. This further prevents condensation, dust, and particulate matter from entering the electrical component box and better directs the return airflow, improving heat dissipation. Furthermore, in terms of height, regardless of whether the air handling unit is installed in a forward or reverse orientation, the baffle effectively prevents condensation, dust, or particulate matter from entering the electrical component box and better directs the return airflow, improving heat dissipation.

[0108] In addition, in this embodiment, the baffle is an arc-shaped plate and also covers both end edges of the long strip opening, which can further prevent condensed water, dust, particulate matter, etc. from entering the interior of the electrical component box.

[0109] In some embodiments, Figures 5 to 7 The electrical component box shown is suitable for scenarios where the air handling device 100 is installed in a forward orientation (ie, the top plate is on top and the bottom plate is on the bottom) or a reverse orientation (ie, the top plate is on the bottom and the bottom plate is on the top).

[0110] In addition, Figure 7 In the figure, the opening is not shown because it is covered by the baffle 124. Here, the baffle is a curved plate, and it can also be a straight plate arranged obliquely downward. Even if condensed water is generated, the condensed water can fall down along the baffle at a position away from the opening and will not enter the interior of the electrical component box.

[0111] Figure 8 It is a front view of another embodiment of the electrical component box of the utility model.

[0112] like Figure 8 As shown, the opening extends along the length direction (x direction) of the electrical component box 120. A baffle 124-1 is provided on the upstream edge of the opening in the airflow direction, extending away from the return air outlet. Furthermore, a baffle 124-2 is provided on the upper edge of the opening, extending toward the bottom plate of the housing. In other words, baffles are provided on both the upstream edge and the upper edge of the opening in the airflow direction.

[0113] In addition, it is assumed that after the electrical component box 120 is installed in the housing 110, the baffle 124 faces Figure 1 The bottom plate 112 of the housing 110 shown in FIG. 1 is extended.

[0114] In this way, condensed water, dust, particulate matter, etc. can be further prevented from entering the interior of the electrical component box, and the return air flow can be better guided to improve the heat dissipation effect.

[0115] In some embodiments, Figure 8 The electrical component box shown is suitable for a scenario where the air handling device 100 is installed in a forward direction (ie, the top plate is on top and the bottom plate is on the bottom).

[0116] In some embodiments, as Figure 3 and Figure 4 As shown, the air handling device 100 further includes a snap-fit portion 191 and a limiting portion 192. The snap-fit portion 191, the limiting portion 192, and the housing side wall 111 form a snap-fit area, and one end of the electrical component box 120 is snap-fitted into the snap-fit area. Figure 3 As shown, the other end of the electrical component box 120 is connected to the side wall 111 of the housing via a fixing member 125. That is, in the thickness (height) direction of the electrical component box 120, one side of the electrical component box 120 is engaged with the engaging portion 191, and the other side is connected to the side wall 111 of the housing via the fixing member 125.

[0117] In some embodiments, when the electrical component box needs to be inspected, the electrical component box 120 can be inspected from the maintenance port on the top panel or side panel of the shell. Specifically, at least one of the top panel or the side panel is provided with a maintenance port, and the maintenance port corresponds to the position of the heat exchange core, and a maintenance cover is provided at the maintenance port; when repairing the electrical component box 120, first open the maintenance cover and take out the heat exchange core. If a filter is provided near the heat exchange core, the filter can also be taken out together, and then the electrical component box can be inspected through the maintenance port. Since the hole for the wires to pass through and be arranged on the electrical component box is set on the side away from the return air outlet, close to the maintenance port, it is convenient to disassemble the wires.

[0118] Since the electrical component box is arranged at the end away from the maintenance port, the electrical component box can be taken out by simply removing the screws at the end close to the maintenance port, which is convenient for installation and removal.

[0119] For example, the engaging portion 191 is formed of foam and is integrally formed with the damper bracket 153 , and specifically may be integrally formed of foam to form a heat-insulating cavity.

[0120] In some embodiments, as Figure 4 and Figure 2Shown, the clamping portion 191 contacts the partial area of the box cover of the electrical component box 120, and the opening 123 is arranged on the position outside this partial area on the box cover. That is, the clamping portion avoids the opening and is provided with, thereby avoiding the clamping portion to block the opening, and can effectively dissipate heat.

[0121] In some embodiments, in the height direction of the housing, the limiting portion is disposed between the electrical component box 120 and the top plate of the housing, or the limiting portion 192 may also be disposed between the electrical component box 120 and the bottom plate of the housing.

[0122] In some embodiments, a limiting portion 192 may be provided between the electrical component box 120 and the top plate of the housing and between the electrical component box 120 and the bottom plate of the housing.

[0123] In addition, for example, the limiting portion 192 is a limiting block. In this way, since the height of the electrical component box is less than the height of the housing, by setting the limiting portion 192, the electrical component box can be prevented from moving in the height direction in various installation and maintenance scenarios and during use, thereby ensuring the stability of the device operation. In some embodiments, such as Figure 3 and Figure 4 As shown, the limiting portion 192 is positioned at a corner within the housing. This can reduce the impact on airflow and heat dissipation within the air handling device. Alternatively, for example, the limiting portion can be positioned corresponding to the engaging portion, without a fastening mechanism. Instead, the limiting portion can cooperate with the engaging portion to secure the electrical component box.

[0124] Thus, the engaging portion 191 and the side wall of the housing restrict the position of the electrical component box in the thickness direction of the electrical component box (i.e., the thickness of the box body and the box cover, such as the y direction);

[0125] The limiting block 192 and the bottom plate of the housing limit the position of the electrical component box in the height direction of the electrical component box (ie, the direction from the top plate to the bottom plate, such as the z direction).

[0126] Figure 9 This is a three-dimensional view from another angle of an implementation manner of the electrical component box according to an embodiment of the present invention.

[0127] For example, combined with Figures 3 to 9 As shown, the fixing component 125 is a fixing plate, and the fixing edge of the fixing plate is formed by, for example, a sheet metal flanging; a screw hole 126 is provided on the fixing plate, so that the fixing plate can be fixed to the side wall 111 by bolts, thereby fixing one side of the electrical component box 120 to the side wall 111 of the shell, and the other side is fixed by the snap-fit portion 191.

[0128] In this way, only one side needs to be provided with a fixing component, which can reduce the use of fixing components and facilitate the installation, disassembly and maintenance of the electrical component box.

[0129] Additionally, in some embodiments, Figure 4 and Figure 5 As shown, there is a gap between the electrical component box 120 and the side wall 111. Figure 9 As shown, the space formed by the gap can accommodate the parts of certain components in the electrical component box 120 that extend from the back of the box body 121 (such as circuit board fixing buckles, ends of fixing screws, etc.), such as the outer end of the fixing column 127 that accommodates the control circuit board; and the gap can also form a heat dissipation space to further improve the heat dissipation effect.

[0130] In some embodiments, as Figure 4 and Figure 5 As shown, the box body 121 of the electrical component box is provided with a hole 129 on the side 128 away from the return air port 115. The hole 129 can be used for the wire to pass through, and heat can also be dissipated through the hole 129.

[0131] In this way, the passage and arrangement of the wires are facilitated, and the hot air flow in the electrical component box can be discharged through the hole 129 and discharged to the outside of the equipment along with the return air flow, further improving the heat dissipation effect.

[0132] In addition, if Figure 4 As shown, a cable tie 193 can also be provided in the housing for fixing the wires.

[0133] In some embodiments, the box body of the electrical component box has a convex portion protruding toward the outside of the box body, and the convex portion may also be called a convex bump.

[0134] Figure 10 FIG. 1 is a schematic diagram of another embodiment of the electrical component box of the present utility model. Figure 10 As shown, a convex portion 122 - 1 protruding outward is formed on the cover of the electrical component box 120 , so that the space formed by the convex portion 122 - 1 can accommodate the protruding parts of certain components in the box body 121 , such as the capacitor on the control circuit board.

[0135] In addition, the protrusion 122 - 1 and the opening 123 are arranged at different positions on the box cover.

[0136] In this way, the space formed by the protrusion can accommodate the protruding parts of certain components in the electrical component box, such as accommodating capacitors with a certain height in the electrical component box, which is conducive to miniaturization and can also form a heat dissipation space to further improve the heat dissipation effect.

[0137] In addition, it is advantageous for miniaturization of the electrical component box. For example, the convex portion is arranged away from the position of the engaging portion.

[0138] In the above embodiment, the electrical component box is arranged in the housing of the air handling device. However, the connection terminal for connecting to the municipal power can be arranged outside the housing. In this case, a wire hole connecting the electrical component box and the connection terminal is provided on the housing.

[0139] In addition, a wire groove structure may be provided on the foam of the heat-insulating cavity, or a wire buckle may be integrally formed on the housing of the air supply fan or the exhaust fan to facilitate fixing of the connecting wires.

[0140] In the above embodiment, the air supply fan and the exhaust fan are driven by different motors, that is, two motors are provided to drive the air supply fan and the exhaust fan respectively. However, in some embodiments, a single motor may be provided to drive the air supply fan and the exhaust fan.

[0141] Figure 11 This is a top view of another embodiment of the internal structure of the air handling equipment of the utility model. Figure 11 As shown, the housing of the air handling device 100" is provided with an air supply fan 131 near the air supply port 114 and an exhaust fan 132 near the exhaust port 116, as well as a heat exchange core 140; different from the above embodiment, the air supply fan 131 and the exhaust fan 132 are driven by the same motor 194, that is, a single-motor dual-fan structure is formed. Other structures can refer to the description of the above embodiment and will not be repeated here.

[0142] According to the above embodiment, an opening is provided on the cover of the electrical component box relatively close to the return air outlet, so that the hot air flow caused by the heating of the electrical components in the electrical component box can be discharged through the opening and discharged to the outside of the air handling device along with the return air flow, thereby improving the heat dissipation effect of the electrical components in the electrical component box and ensuring the electrical safety and performance of the air handling device;

[0143] In addition, by providing a baffle extending toward the outside of the electrical component box at the edge of the opening on the upstream side of the airflow direction, on the one hand, it can prevent condensed water, dust, particulate matter, etc. inside the air handling equipment from entering the interior of the electrical component box and causing electrical safety problems. On the other hand, it can guide the direction of the return air flow and further improve the heat dissipation effect.

[0144] Furthermore, the opening extends along the width direction of the electrical component box, and the baffle is arranged on the side of the opening close to the return air outlet, and the baffle extends in the direction away from the return air outlet, thereby further preventing condensed water, dust, particulate matter, etc. from entering the interior of the electrical component box and better guiding the return air flow to improve the heat dissipation effect.

[0145] Furthermore, the opening extends along the length direction of the electrical component box, and the baffle is arranged on the edge of the upper side of the opening, and the baffle extends toward the bottom plate of the shell, thereby further preventing condensed water, dust, particulate matter, etc. from entering the interior of the electrical component box and better guiding the return air flow to improve the heat dissipation effect.

[0146] Furthermore, the electrical component box is arranged in the corner of the shell near the return air outlet. In this way, other components inside the air treatment equipment can be reasonably arranged, reducing the impact on the air flow inside the air treatment equipment. By setting the electrical component box in an area with less air flow such as the corner, the pressure loss of the whole machine can be reduced, which is conducive to the miniaturization of the whole machine.

[0147] Furthermore, by providing the engaging portion, the use of fixing components can be reduced, making it easier to disassemble, assemble and repair the electrical component box.

[0148] Furthermore, by providing a limit portion, the electrical component box can be prevented from moving in the height direction in various installation and maintenance scenarios and during use, thereby ensuring the stability of the equipment operation.

[0149] Furthermore, the limiting portion is arranged at a corner inside the shell, which can reduce the impact on the air flow and heat dissipation inside the air handling device.

[0150] Furthermore, the box body of the electrical component box is provided with a hole on the side away from the return air outlet, so that the wires can be passed through and arranged conveniently. In addition, the hot air flow in the electrical component box can be discharged through the hole and discharged to the outside of the equipment along with the return air flow, thereby further improving the heat dissipation effect.

[0151] Furthermore, there is a gap between the electrical component box and the side wall fixing the electrical component box, so that the space formed by the gap can accommodate the protruding parts of certain components in the electrical component box and can also form a heat dissipation space to further improve the heat dissipation effect.

[0152] Furthermore, the box body of the electrical component box has a convex portion protruding toward the outside of the box body, so that the space formed by the convex portion can accommodate the protruding parts of certain components in the electrical component box and can also form a heat dissipation space to further improve the heat dissipation effect.

[0153] Furthermore, a plurality of such openings are provided on the cover of the electrical component box, and the openings are in the shape of long strips, and the baffle is provided on at least one long side of the opening. In this way, the cover structure is simple, which can further improve the heat dissipation effect of the opening, and further improve the effect of the baffle in preventing condensed water, dust, particulate matter, etc. from entering the interior of the electrical component box and guiding the return air flow.

[0154] Furthermore, the baffle is straight or curved, so that it can be freely designed according to actual conditions, improving manufacturing efficiency and further improving the baffle's ability to prevent condensed water, dust, particulate matter, etc. from entering the interior of the electrical component box and to guide the return air flow.

[0155] The present invention has been described above with reference to specific embodiments. However, those skilled in the art should understand that these descriptions are merely illustrative and are not intended to limit the scope of protection of the present invention. Those skilled in the art may make various modifications and variations to the present invention based on the spirit and principles of the present invention, and such modifications and variations are also within the scope of the present invention.
