Description

Technical Field

[0001] This utility model relates to the field of home appliance technology, specifically to an air outlet grille assembly and a home appliance with an air outlet grille. Background Technology

[0002] In existing electrical products such as baseboard heaters, the display module and motherboard module are usually installed on different components. This makes pre-installation of the connecting cables between the display module and the motherboard inconvenient. Typically, the motherboard is assembled on the inner wall of the entire unit first, then the connecting cables for all components except the display module are connected. Next, the connecting cables for the assembled display module are connected to the motherboard, and finally, the display module is assembled onto the entire unit. This is extremely inconvenient for production and installation. Furthermore, the motherboard's early installation order means that subsequent disassembly and repair require disassembling the unit much later to access the motherboard, which is very inconvenient and impacts production and assembly efficiency. Utility Model Content

[0003] In view of this, the present invention provides an air outlet grille assembly and a household appliance with an air outlet grille to solve the problems in the prior art where the display module and the motherboard module of the household appliance are installed on different components, which is inconvenient for pre-installation of the connection wires between the display module and the motherboard module. In addition, the motherboard is installed earlier, and subsequent disassembly and maintenance requires disassembling to a later stage to inspect the motherboard, which is very inconvenient and affects the production and assembly efficiency.

[0004] In a first aspect, this utility model provides an air outlet grille assembly, comprising:

[0005] Air vent grille;

[0006] The display module is installed on the air vent grille;

[0007] The motherboard module is detachably mounted on the air vent grille, and the motherboard module is located on the side of the display module away from the air vent grille.

[0008] Beneficial Effects: By mounting both the display module and motherboard module on the air vent grille, pre-installation of the connecting cables between the two modules is convenient. This pre-assembled component also improves production assembly efficiency. Furthermore, since the air vent grille is typically installed last and removed first, subsequent disassembly and maintenance only requires removing the grille to access the motherboard, making motherboard maintenance more convenient in the overall assembly sequence. Moreover, because the motherboard module is located outside the display module, it can be accessed directly without disassembling the display module, making motherboard maintenance more convenient and efficient. Therefore, this solves the problems of existing home appliances where the display module and motherboard module are installed on separate components, making pre-installation of the connecting cables inconvenient, and requiring the motherboard to be installed earlier in the assembly sequence, resulting in significant inconvenience and reduced production assembly efficiency.

[0009] In one alternative implementation, the motherboard module includes:

[0010] Motherboard;

[0011] The motherboard bracket is detachably mounted on the air vent grille, and the motherboard is detachably mounted on the side of the motherboard bracket away from the air vent grille.

[0012] Beneficial effects: The designed motherboard bracket allows for assembly where the motherboard bracket is first installed on the air outlet grille, followed by the motherboard itself. Alternatively, the assembled motherboard bracket and motherboard can be installed together on the air outlet grille. This not only improves production and assembly efficiency but also avoids the inconvenience of directly mounting the motherboard on the air outlet grille, as well as the high requirements for the corresponding mounting structure, processing difficulties, and molding challenges associated with directly mounting the motherboard on the grille. Furthermore, by detachably mounting and fixing the motherboard to the side of the motherboard bracket furthest from the air outlet grille, the motherboard is positioned on the outside of the bracket, making it easier to inspect and maintain, and facilitating disassembly and assembly.

[0013] In one alternative implementation, the motherboard bracket includes:

[0014] Support body;

[0015] The grille assembly structure and the main board mounting structure are set on opposite sides of the main body of the bracket;

[0016] The grille assembly structure is fixed to the air outlet grille, and the main board mounting structure is fixed to the main board by screws and / or snap-fit ​​connections.

[0017] Beneficial effects: The motherboard bracket is fixed to the motherboard and the air vent grille by screws and / or clips, which not only ensures a reliable and stable connection but also facilitates disassembly and assembly.

[0018] In one alternative implementation, the motherboard mounting structure includes:

[0019] The motherboard mounting slot is formed on the side of the bracket body away from the air outlet grille, and the motherboard is embedded in the motherboard mounting slot.

[0020] The motherboard is fixed in the motherboard mounting slot by the first screw connection and / or the first snap fastener.

[0021] Beneficial effects: The motherboard mounting slot can accommodate and limit the motherboard. During assembly, the motherboard is first inserted into the motherboard mounting slot at a set angle. When the first "click" sound is heard, the motherboard is pre-fixed. Then, a screw is driven between the first screw connection and the motherboard to complete the final fixation of the motherboard. The first snap can pre-fix the position of the motherboard to prevent it from moving and facilitate subsequent screwing operations. The first screw connection can fix the position of the motherboard, making it securely and stably fixed on the motherboard bracket.

[0022] In one optional embodiment, there are two first screw connectors and two first latches, with the two first screw connectors symmetrically distributed relative to the first diagonal of the motherboard and the two first latches symmetrically distributed relative to the second diagonal of the motherboard.

[0023] Beneficial effects: The two first clips and two first screws are designed to be diagonally distributed, which can effectively ensure the motherboard is under balanced force and avoid the problem of the motherboard being unstable and loose due to unbalanced force.

[0024] In one alternative embodiment, the grille assembly structure includes:

[0025] The second screw connection part is provided on the side of the bracket body near the air outlet grille. The air outlet grille is provided with a corresponding second screw mating connection part. The second screw connection part and the second screw mating connection part are connected by screws.

[0026] The guide section and the air outlet grille are respectively provided with guide mating parts. The guide section and the guide mating parts are positioned and mated to position the bracket body at the assembly position corresponding to the second screw connection part and the second screw mating connection part.

[0027] Beneficial effects: The motherboard bracket and the air vent grille are connected by screws, which is a reliable and stable connection. Furthermore, the positioning and cooperation of the guide part and the guide mating part can pre-position the bracket body during assembly, so that the bracket body can be quickly and accurately positioned at the assembly position corresponding to the second screw connection part and the second screw mating connection part, thereby improving assembly efficiency.

[0028] In one alternative embodiment, the guide portion includes a guide post, the guide post comprising:

[0029] The guide section and the limiting section have a smaller outer diameter than the limiting section, and a positioning step surface is formed between the guide section and the limiting section.

[0030] The guide mating part includes a guide rib, a guide groove is formed inside the guide rib, the guide section is adapted to be inserted and positioned into the guide groove, and the positioning step surface is adapted to abut and limit the end face of the guide rib.

[0031] Beneficial effects: The guide post is suitable for insertion into the guide rib to form a positioning. Furthermore, by adopting the design of guide sections and limiting sections with different outer diameters, the guide post can form a positioning step surface between the guide section and the limiting section. This positioning step surface can abut against and limit the end face of the guide rib when the guide post is inserted into the guide rib, thereby forming a positioning and ensuring that the insertion depth of the guide part is appropriate. In turn, it can effectively ensure that the second screw connection part and the second screw mating connection part make contact and fit, which is convenient for screw driving.

[0032] In one alternative implementation, the display module includes:

[0033] The display control panel is mounted on the air vent grille, and the display control panel is detachably mounted and fixed in the display control panel mounting area.

[0034] The air vent grille has a motherboard mounting area, which at least partially covers the display control board mounting area;

[0035] The motherboard module is detachably mounted and fixed in the motherboard mounting area, and is located on the side of the display control board away from the air vent grille.

[0036] Beneficial effects: By covering at least part of the display control board mounting area with the motherboard mounting area and placing the motherboard module on the outside of the display control board, the overall structure can be made more compact, reducing the area occupied by the display control board and motherboard module on the air vent grille and improving space utilization.

[0037] In one optional embodiment, the display control board mounting area is provided with a third screw connection and / or a second snap fastener, and the display control board is fixed in the display control board mounting area by the third screw connection and / or the second snap fastener.

[0038] In one alternative embodiment, two third screw connectors and two second clips are provided;

[0039] The two third screw connectors and the two second clips are arranged in a quadrilateral shape, and the two third screw connectors and the two second clips are arranged opposite each other at the four corners of the quadrilateral.

[0040] Beneficial effects: The two third screw connections and the two second clips are arranged in a quadrilateral shape, and are positioned opposite each other at the four corners of the quadrilateral. This forms a balanced four-corner support system, which effectively ensures the balance of forces on the display control board and prevents the display control board from becoming unstable or loose due to unbalanced forces, thus improving the stability of the display control board.

[0041] In one alternative implementation, the display module includes:

[0042] The display panel has a display area on the air vent grille, and the display panel is snapped and fixed to the display area.

[0043] Beneficial effects: The display panel is fixed to the display area of ​​the air vent grille by snap-fit, forming a screwless fixation that is convenient for disassembly and assembly.

[0044] Secondly, this utility model also provides a household appliance, including:

[0045] The casing is equipped with an air outlet;

[0068] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0069] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0070] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0071] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0072] In existing electrical products such as baseboards, the display module and motherboard module are usually fixed on different components, making it inconvenient to pre-install the connection cables between the display module and the motherboard module. Generally, the motherboard needs to be assembled on the previously installed components first, then the connection cables other than the display module need to be connected first, then the connection cables of the assembled display module need to be connected to the motherboard, and finally the display module is installed on the whole machine. This is very inconvenient for production and installation. Moreover, the motherboard is installed earlier, which means that subsequent disassembly and maintenance requires disassembling the machine much later to inspect the motherboard, which is very inconvenient and affects production and assembly efficiency.

[0073] Specifically, in the related technology, the baseboard heater uses screws and clips to mount the mainboard onto the back cover. Since the baseboard back cover assembly is installed at the front of the unit, subsequent disassembly and repair require reaching very far back to inspect the mainboard, resulting in low production efficiency. Furthermore, the heavy mainboard shifts the unit's center of gravity towards the rear, leading to poor stability, high safety risks, and difficulty passing inclined platform tests.

[0074] The following is combined with Figures 1 to 11 The following describes embodiments of the present invention.

[0075] According to embodiments of the present invention, on the one hand, in conjunction with Figures 1 to 10 As shown, this utility model provides an air outlet grille assembly 10, including: an air outlet grille 11, a display module 12, and a main board module 13. The display module 12 is mounted on the air outlet grille 11; the main board module 13 is detachably mounted on the air outlet grille 11, and the main board module 13 is located on the side of the display module 12 away from the air outlet grille 11.

[0076] In the above embodiments, by mounting both the display module 12 and the motherboard module 13 on the air outlet grille 11, it is not only convenient to pre-install the connection lines between the display module and the motherboard module, but also to improve production assembly efficiency. Furthermore, since the air outlet grille 11 is generally installed last and removed first, subsequent disassembly and maintenance only requires removing the air outlet grille 11 to inspect the motherboard 131, making the overall assembly sequence more convenient for motherboard 131 maintenance. Moreover, since the motherboard module 13 is located outside the display module 12, maintenance of the motherboard 131 can be performed directly without disassembling the display module 12, making motherboard 131 maintenance more convenient and faster. Therefore, this solves the problems in the prior art where the motherboard 131 and the display control board 121 are mounted on different components, making pre-installation of the connection lines between the display module and the motherboard module inconvenient, and the motherboard 131 being installed earlier, requiring subsequent disassembly and maintenance to be performed much later, which is very inconvenient and affects production assembly efficiency.

[0077] Specifically, the display module 12 is detachably mounted on the air outlet grille 11, facilitating its installation and removal. Both the display module 12 and the mainboard module 13 are fixed to the air outlet grille 11 via screws and / or snap-fit ​​connections. Furthermore, the mainboard module 13 is located outside the display module 12, allowing for direct removal of the air outlet grille assembly 10 for maintenance and repair without disassembling the display module 12, thus enhancing the convenience of maintenance and repair of the mainboard 131.

[0078] It should be noted that in this embodiment, the air outlet grille assembly 10 is applied to household appliances with air outlet grilles, including but not limited to air purifiers, air conditioners, humidifiers, and baseboard heaters. Preferably, the air outlet grille assembly 10 is applied to a baseboard heater, and the air outlet grille assembly 10 is installed at the air outlet on the top of the baseboard heater. The main board module 13 is located below the air outlet grille 11 and the display module 12. The main board module 13 is the main control system of the entire machine.

[0079] In some embodiments, combined with Figure 2 , Figure 3 as well as Figures 5 to 11 As shown, the motherboard module 13 includes a motherboard 131 and a motherboard bracket 132. The motherboard bracket 132 is detachably mounted and fixed on the air outlet grille 11, and the motherboard 131 is detachably mounted and fixed on the side of the motherboard bracket 132 away from the air outlet grille 11.

[0080] In the above embodiments, by using the motherboard bracket 132, during assembly, the motherboard bracket 132 can be installed on the air outlet grille 11 first, and then the motherboard 131 can be installed on the motherboard bracket 132. Alternatively, the assembled motherboard bracket 132 and motherboard 131 can be installed together on the air outlet grille 11. This not only improves production assembly efficiency but also avoids the problems of inconvenient disassembly and assembly caused by directly installing the motherboard 131 on the air outlet grille 11, as well as the high requirements for the corresponding installation structure on the air outlet grille 11, inconvenient processing, and difficult molding. Furthermore, by detachably installing and fixing the motherboard 131 on the side of the motherboard bracket 132 away from the air outlet grille 11, the motherboard 131 is located on the outside of the motherboard bracket 132, making it easier to inspect and maintain, and also facilitating disassembly and assembly.

[0081] In some embodiments, the motherboard bracket 132 includes a bracket body 1321, a grille assembly structure, and a motherboard mounting structure. The grille assembly structure and the motherboard mounting structure are disposed on opposite sides of the bracket body 1321. The grille assembly structure is fixed to the air outlet grille 11, and the motherboard mounting structure is fixed to the motherboard 131 by screw connection and / or snap-fit ​​connection.

[0082] In the above embodiments, the motherboard bracket 132 is fixed to the motherboard 131 and the air vent grille 11 by screw connection and / or snap-fit, which not only ensures a reliable and stable connection but also facilitates disassembly and assembly.

[0083] In some embodiments, combined with Figure 2 , Figure 3 , Figure 5 , Figure 7 and Figure 8 As shown, the motherboard mounting structure includes a motherboard mounting slot 1322, a first screw connection 1323 and / or a first snap fastener 1324. The motherboard mounting slot 1322 is formed on the side of the bracket body 1321 away from the air outlet grille 11. The motherboard 131 is embedded in the motherboard mounting slot 1322. The motherboard 131 is fixed in the motherboard mounting slot 1322 by the first screw connection 1323 and / or the first snap fastener 1324.

[0084] Preferably, there are two first screw connecting parts 1323 and two first buckles 1324. The two first screw connecting parts 1323 are symmetrically distributed with respect to the first diagonal of the motherboard 131, and the two first buckles 1324 are symmetrically distributed with respect to the second diagonal of the motherboard 131.

[0085] In the above embodiment, the motherboard mounting slot 1322 can accommodate and limit the motherboard 131. During assembly, the motherboard 131 is first inserted into the motherboard mounting slot 1322 at a set angle. After hearing the "click" sound of the first latch 1324, the motherboard 131 is pre-fixed. Then, a screw is driven between the first screw connection part 1323 and the motherboard 131 to complete the final fixation of the motherboard 131. The first latch 1324 can pre-fix the position of the motherboard 131 to prevent the motherboard 131 from moving and facilitate the subsequent screw driving operation. The first screw connection part 1323 can fix the position of the motherboard 131, making it securely and stably fixed on the motherboard bracket 132. Furthermore, the two first latches 1324 and the two first screw connection parts 1323 are designed to be diagonally distributed, which can effectively ensure the force balance of the motherboard 131 and avoid the problem of unstable position and easy loosening of the motherboard 131 due to unbalanced force.

[0086] Specifically, the motherboard mounting slot 1322 is a recessed structure located on the back of the motherboard bracket 132, and the inner circumferential shape and dimensions of the motherboard mounting slot 1322 match the outer circumferential shape and dimensions of the motherboard 131. The first screw connection part 1323 is a screw hole or bolt post.

[0087] Preferably, the motherboard mounting slot 1322 has multiple supporting ribs spaced circumferentially inside, and the motherboard 131 is supported and positioned on the supporting ribs. The supporting ribs can provide good support for the motherboard 131 and also avoid the problem of the motherboard 131 being too close to the bottom of the motherboard mounting slot 1322, making it inconvenient to remove.

[0088] In some embodiments, combined with Figure 2 , Figure 3 , Figures 6 to 9 As shown, the grille assembly structure includes a second screw connection portion 1325, which is disposed on the side of the support body 1321 near the air outlet grille 11. A corresponding second screw mating connection portion 111 is provided on the air outlet grille 11. The second screw connection portion 1325 and the second screw mating connection portion 111 are connected by screws. The grille assembly structure also includes a guide portion 1326, and a corresponding guide mating portion 112 is provided on the air outlet grille 11. The guide portion 1326 and the guide mating portion 112 are positioned together to position the support body 1321 at the assembly positions corresponding to the second screw connection portion 1325 and the second screw mating connection portion 111.

[0089] In the above embodiment, the motherboard bracket 132 and the air vent grille 11 are connected by screws, which is a reliable and stable connection. Furthermore, through the positioning and cooperation of the guide part 1326 and the guide mating part 112, the position of the bracket body 1321 can be pre-positioned during assembly, so that the bracket body 1321 can be quickly and accurately positioned at the assembly position corresponding to the second screw connection part 1325 and the second screw mating connection part 111, thereby improving assembly efficiency.

[0090] In some embodiments, such as Figure 3 and Figure 6 As shown, the guide part 1326 includes a guide post, which includes a guide section 13261 and a limiting section 13262. The outer diameter of the guide section 13261 is smaller than the outer diameter of the limiting section 13262. A positioning step surface 13260 is formed between the guide section 13261 and the limiting section 13262. The guide mating part 112 includes a guide rib, in which a guide groove is formed. The guide section 13261 is adapted to be inserted and positioned into the guide groove, and the positioning step surface 13260 is adapted to abut against and limit the end face of the guide rib.

[0091] In the above embodiment, the guide post is adapted to be inserted into the guide rib to form a positioning. By adopting the design of guide sections 13261 and limiting sections 13262 with different outer diameters, the guide post can form a positioning step surface 13260 between the guide section 13261 and the limiting section 13262. The positioning step surface 13260 can abut against and limit the end face of the guide rib when the guide post is inserted into the guide rib, thereby forming a positioning and ensuring that the insertion depth of the guide part 1326 is appropriate. In this way, it can effectively ensure that the second screw connection part 1325 and the second screw mating connection part 111 are in contact and mating, which is convenient for screwing.

[0092] Preferably, in this embodiment, the guide post is a non-circular post, and the guide post is a triangular or polygonal columnar structure. By adopting a non-circular post design, the guide post not only serves as a guide and positioning tool, but also prevents mistaken identity. It also avoids the problem of the motherboard bracket 132 rotating and shifting during assembly, which would cause inconvenience in assembly. More preferably, in this embodiment, the guide post is a hollow rectangular post.

[0093] Furthermore, multiple reinforcing ribs are spaced around the guide section 13261 to increase its structural strength. The positioning step surface 13260 is a plane perpendicularly connected between the guide section 13261 and the limiting section 13262, allowing the positioning step surface 13260 to form surface-to-surface contact with the end face of the guide rib, resulting in better positioning.

[0094] Furthermore, such as Figure 6As shown, there are four second screw connecting parts 1325, which are distributed at the four corners of the main board bracket 132, forming a balanced four-corner support system. Each second screw connecting part 1325 is either a screw hole or a bolt post. Preferably, the second screw connecting part 1325 is a bolt post. Four second screw mating connecting parts 111 are also provided, each being a bolt post integrally formed on the air outlet grille 11. The design of both the second screw connecting parts 1325 and the second screw mating connecting parts 111 as bolt posts allows the main board 131 to be suspended below the air outlet grille 11, and provides a predetermined gap between the main board bracket 132 and the air outlet grille 11 to facilitate the installation of the display control board 121.

[0095] Alternatively, in other alternative embodiments, the second screw connection portion 1325 includes a partially outwardly protruding molded structure of the motherboard bracket 132 and a screw hole formed on the molded structure. At least one of the second screw connection portion 1325 and the second screw mating connection portion 111 has a set extension length so that the motherboard bracket 132 is supported and fixed at a set interval position below the air vent grille 11 to avoid interference with the display control board 121.

[0096] In some embodiments, the display module 12 includes a display control board 121, an air vent grille 11 having a display control board mounting area 110, and the display control board 121 being detachably mounted and fixed in the display control board mounting area 110; the air vent grille 11 having a motherboard mounting area, the motherboard mounting area at least partially covering the display control board mounting area 110; and a motherboard module 13 being detachably mounted and fixed in the motherboard mounting area and located on the side of the display control board 121 away from the air vent grille 11.

[0097] In the above embodiments, by covering at least part of the display control board mounting area 110 with the motherboard mounting area and setting the motherboard module 13 on the outside of the display control board 121, the overall structure can be made more compact, reducing the area occupied by the display control board 121 and the motherboard module 13 on the air vent grille 11 and improving space utilization.

[0098] Specifically, the size of the display control board 121 is smaller than that of the main board bracket 132. After the main board bracket 132 is installed on the air outlet grille 11, there is a set gap between it and the air outlet grille 11. The display control board 121 is located within this gap, which can make full use of the idle space and improve space utilization. The second screw connection part 1325 and the second screw mating connection part 111 can support and fix the main board bracket 132 at the installation position at a set gap from the air outlet grille 11. The second screw connection part 1325, the second screw mating connection part 111, the main board bracket 132, and the air outlet grille 11 form an installation space that can accommodate the display control board 121. The display control board 121 and the main board module 13 are stacked on the air outlet grille 11, which makes the space layout more reasonable and occupies less area.

[0099] In some embodiments, such as Figure 2 and Figure 3 As shown, the display control board mounting area 110 is provided with a third screw connection part 113 and / or a second buckle 114, and the display control board 121 is fixed to the display control board mounting area 110 by the third screw connection part 113 and / or the second buckle 114.

[0100] Preferably, there are two third screw connecting parts 113 and two second buckles 114; the two third screw connecting parts 113 and the two second buckles 114 are arranged in a quadrilateral shape, and the two third screw connecting parts 113 and the two second buckles 114 are arranged opposite each other at the four corner positions of the quadrilateral.
