Description

Technical Field

[0001] This utility model relates to the field of home appliance technology, specifically to household appliances. Background Technology

[0002] During use, electric heaters may be used in humid environments, where water can easily enter the heater through gaps in the heater casing. This can cause short circuits or damage to electrical components (such as circuit boards, fans, and heating elements), severely affecting the lifespan of the heater and even causing safety accidents such as fires or electric shocks. Utility Model Content

[0003] In view of this, the present invention provides a household appliance to solve the problem of poor waterproof performance in electric heaters.

[0004] This utility model provides a household appliance, including:

[0005] case;

[0006] An air outlet grille is installed on the housing, and the air outlet grille is provided with an air outlet; the air outlet grille is provided with an electrical component mounting area, and the electrical component mounting area is provided with assembly holes;

[0007] The display module includes a display panel mounted on the outside of the air outlet grille, and a display plate disposed on the inside of the air outlet grille corresponding to the electrical component mounting area; the display plate at least partially passes through the mounting hole;

[0008] A sealing structure is provided between the display panel and the air outlet grille, and is arranged around the outer periphery of the electrical component mounting area.

[0009] Beneficial effects: By sealing the display panel and the air vent grille with a sealing structure that surrounds the outer periphery of the electrical component mounting area, external water flow can be effectively prevented from seeping into the electrical component mounting area along the joint between the display panel and the grille. External water flow is blocked by the sealing structure at the periphery of the electrical component mounting area, preventing it from directly contacting or flowing into the assembly holes of the internal electrical component mounting area. This isolates the path for external water flow to intrude into the display panel and other electronic components, significantly improving the waterproof protection level of household appliances, ensuring the safe and stable operation of internal electrical components, and enhancing the reliability and service life of household appliances.

[0010] In one optional embodiment, the air outlet grille includes a mounting portion and a grille portion, and the electrical component mounting area is located on one side of the mounting portion;

[0011] The sealing structure includes a flow-blocking edge that surrounds the outer periphery of the electrical component mounting area and protrudes from the side wall of the mounting portion away from the housing.

[0012] Beneficial effects: Since the flow-blocking edge is set around the outer periphery of the electrical component mounting area and protrudes from the side wall away from the housing of the mounting part, the height of external water flow entering the electrical component mounting area is increased, forming a waterproof barrier around the outer periphery of the electrical component mounting area.

[0013] In one optional embodiment, the mounting part includes a mounting groove, and the display panel is mounted in the mounting groove; the flow-blocking edge protrudes from the bottom of the mounting groove and abuts against the display panel.

[0014] Beneficial effects: By mounting the display panel within the mounting slot, the slot improves the assembly precision of the display panel and provides effective circumferential limiting support, preventing displacement of the display panel under external forces. This avoids damage to the sealing interface between the display panel and the baffle edge due to displacement, ensuring the long-term reliability of the sealing structure. Furthermore, the abutting fit between the baffle edge and the display panel forms an effective line seal or surface seal at their contact surface, ensuring that external water flow is strictly isolated outside the electrical component mounting area and cannot penetrate the internal mounting holes and display panel area. This compact and reliable structure achieves waterproof protection for the display panel and other electronic components.

[0015] In one optional embodiment, the sealing structure further includes:

[0016] A sealing gasket, which is embedded in the mounting groove and surrounds the outer periphery of the flow deflector.

[0017] Beneficial effects: By setting a sealing gasket to fill the assembly gap between the outer periphery of the flow barrier and the wall of the mounting groove between the display panel and the mounting groove, external water flow is effectively prevented from flowing into the mounting groove along the edge of the display panel; and since the sealing gasket is set around the outer periphery of the flow barrier, even if a small amount of external water flows through the sealing gasket, it will be restricted to the outer periphery of the flow barrier and will not be able to penetrate into the electrical component installation area inside the flow barrier, further improving the waterproof level.

[0018] In one optional embodiment, the mounting portion is provided with a first hole, and the projection of the display panel in the vertical direction does not overlap with the projection of the first hole in the vertical direction; and / or, the projection of the sealing structure in the vertical direction does not overlap with the projection of the first hole in the vertical direction.

[0019] Beneficial effects: By setting the first hole, water accumulated on the air outlet grille can be drained; and the vertical projection of the display panel does not overlap with the vertical projection of the first hole, ensuring that the drainage path of the water on the air outlet grille is completely located outside the display panel; the vertical projection of the sealing structure does not overlap with the vertical projection of the first hole, effectively preventing the sealing structure from blocking the drainage channel and ensuring smooth drainage.

[0020] In one alternative embodiment, the display panel is provided with a buckle that engages with the first hole.

[0021] Beneficial effects: The display panel is reliably installed and fixed by directly engaging the buckle on the display panel with the first hole; and since the buckle engages with the first hole, there is no need to open additional penetrating mounting holes on the mounting part, which fundamentally avoids the water seepage path that may be caused by adding mounting holes, thereby maximizing the overall waterproof and sealing performance.

[0022] In an optional embodiment, the system further includes a motherboard module disposed within the housing, comprising:

[0023] The motherboard bracket is mounted on the air outlet grille;

[0024] The motherboard is mounted on the side of the motherboard bracket away from the air outlet grille.

[0025] Beneficial effect: By mounting the motherboard on the side of the motherboard bracket away from the air vent grille, the path of water flowing down from the air vent grille is blocked, thus ensuring that water cannot drip directly onto the motherboard and providing direct waterproof protection for the motherboard.

[0026] In one alternative embodiment, the top wall of the motherboard bracket near the air outlet grille is provided with a gradually downward sloping guide surface.

[0027] In one optional embodiment, the top wall of the motherboard bracket near the air outlet grille is provided with a water collection trough, and a drain outlet is provided on one side of the water collection trough.

[0028] The bottom of the water collection tank gradually slopes downwards towards the direction of the drain outlet to form a guide slope.

[0029] Beneficial effects: By setting a water collection trough on the side of the motherboard bracket near the air vent grille, the trough first intercepts and collects water flowing down from the air vent grille, preventing water from falling directly onto the motherboard below the motherboard bracket. Furthermore, the design of the guide slope allows the water accumulated in the trough to automatically converge towards the drain outlet and be discharged directly from the drain outlet, eliminating the risk of water stagnation in the trough. Through the dual effect of the water collection trough and the guide slope, the water flow is confined to the motherboard bracket, ensuring zero contact between the water flow and core electronic components such as the motherboard throughout the entire process, effectively improving the waterproof performance of household appliances.

[0030] In one alternative embodiment, the bottom of the housing is provided with a second hole for drainage.

[0031] Beneficial effect: By setting a second hole at the bottom of the housing, the water flowing down from the air outlet grille and water collection tank is gathered at the bottom of the housing and completely discharged outside the machine through the second hole, avoiding the accumulation of water inside the housing.

[0032] In one alternative implementation, the household appliance is an electric heater. Attached Figure Description

[0051] 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.

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.

[0053] 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.

[0054] 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.

[0055] The following is combined Figures 1 to 9 The following describes embodiments of the present invention.

[0056] According to the embodiments of this utility model, in conjunction with Figures 1 to 9 As shown, this utility model provides a household appliance, including a housing 1, an air vent grille 2, a display module, and a sealing structure. The air vent grille 2 is mounted on the housing 1 and has an air outlet. The air vent grille 2 has an electrical component mounting area 21, and the electrical component mounting area 21 has mounting holes 22. The display module includes a display panel 31 mounted on the outside of the air vent grille 2 and a display plate 32 corresponding to the electrical component mounting area 21 and located on the inside of the air vent grille 2. The mounting holes 22 allow at least a pressing control spring between the display plate 32 and the display panel 31 to pass through. The sealing structure is sealed between the display panel 31 and the air vent grille 2 and surrounds the outer periphery of the electrical component mounting area 21. The outer periphery of the electrical component mounting area 21 is the outer edge of the electrical component mounting area 21 away from its center. The outside of the air vent grille refers to the side of the air vent grille away from the inside of the housing 1; the inside of the air vent grille 2 refers to the side of the air vent grille 2 facing the inside of the housing 1.

[0057] In the above embodiment, by sealing the display panel 31 and the air vent grille 2 with a sealing structure that surrounds the outer periphery of the electrical component mounting area 21, external water flow can be effectively blocked from penetrating into the electrical component mounting area 21 along the joint between the display panel 31 and the grille. External water flow is blocked by the sealing structure at the periphery of the electrical component mounting area 21, preventing it from directly contacting or flowing into the assembly holes 22 of the internal electrical component mounting area 21. This isolates the path for external water flow to invade electronic components such as the display panel 32, significantly improving the waterproof protection level of the household appliance, ensuring the safe and stable operation of the internal electrical components, and enhancing the reliability and service life of the household appliance.

[0058] In a specific implementation, the electrical component mounting area 21 is the area on the air outlet grille 2 that is opposite to the display panel 32.

[0059] In a specific implementation, the display panel 32 integrates a press control spring, a display screen, a remote control sensor, and electronic components such as capacitors, resistors, and inductors; the display panel 31 includes control buttons and a transparent window. The mounting hole 22 includes a connecting hole 221, a clearance hole 222, a display port 223, and a through hole 224. A pressing control spring passes through the connecting hole 221 and is linked to the control button on the display panel 31 to achieve physical button feedback. The display screen projects the displayed information data onto the transparent window of the display panel 31 through the display port 223, ensuring that the user can clearly read the data. Each capacitor, resistor, and inductor corresponds to a clearance hole 222 during installation. The clearance holes 222 allow for spatial clearance, preventing structural interference between the capacitors, resistors, inductors, and the air vent grille 2 during installation on the display panel 32. The remote control sensor is aligned with the through hole 224. The through hole 224 not only allows for spatial clearance, preventing structural interference between the remote control sensor and the air vent grille 2 during installation on the display panel 32, but also forms a signal channel, ensuring that commands from external remote controls and other devices can be sensed and received by the remote control sensor.

[0060] Specifically, the connecting hole 221 can be constructed as a circular hole to match the shape of the pressing control spring; the clearance hole 222 can be constructed as a square hole to match the shape of components such as capacitors, resistors, and inductors; the display port 223 can be constructed as a square port to match the shape of the display screen; and the through hole 224 can be constructed as a square hole to match the shape of the remote control sensor.

[0061] It should be noted that, in this embodiment, household appliances include, but are not limited to, air purifiers, air conditioners, humidifiers, and electric heaters. Preferably, the household appliance is an electric heater. Figure 2 As shown, the interior of the electric heater may include a humidification component 6, a heating element component 7, and a circuit board assembly. The circuit board assembly includes a main board module 5 and a display board 32. Since both the main board module 5 and the display board 32 are located within an enclosed space formed inside the housing 1, it is necessary to prevent water from flowing from above the housing 1 from entering the interior of the housing 1 and contacting critical electrical components such as the main board module 5 and the display board 32.

[0062] In this application, since a sealing structure is provided between the display panel 31 and the air outlet grille 2, and the sealing structure is arranged around the outer periphery of the electrical component mounting area 21, the external water flow is blocked by the sealing structure at the periphery of the electrical component mounting area 21, and cannot directly contact or flow into the assembly hole 22 of the internal electrical component mounting area 21, thereby blocking the path of external water flow into electronic components such as the display panel 32, thus improving the waterproof level of the circuit board assembly area, thereby effectively improving the waterproof level of the entire electric heater.

[0063] In one embodiment, combined Figure 1, Figure 4 as well as Figure 5 As shown, the air outlet grille 2 includes a mounting portion 23 and a grille portion 24, and the electrical component mounting area 21 is located on one side of the mounting portion 23; the sealing structure includes a baffle 41, which surrounds the outer periphery of the electrical component mounting area 21 and protrudes from the side wall of the mounting portion 23 away from the housing 1.

[0064] In the above embodiment, since the flow-blocking surround 41 is disposed around the outer periphery of the electrical component mounting area 21 and protrudes from the side wall of the mounting portion 23 away from the housing 1, the height at which external water flows into the electrical component mounting area 21 is increased, forming a waterproof barrier around the outer periphery of the electrical component mounting area 21. This ensures that external water flows are isolated outside the electrical component mounting area 21 and cannot penetrate the internal mounting holes 22 and the display panel 32 area, achieving waterproof protection for electronic components such as the display panel 32 with a compact and reliable structure.

[0065] Preferably, a flange is provided on the side wall of the mounting part 23 away from the housing 1. The flange is arranged around the outer periphery of the mounting hole 22. Even if external water flows into the inner side of the baffle 41, the flange can effectively block the water from flowing further into the mounting hole 22, thereby isolating the possibility of water flowing into the internal display panel 32 and other electronic components through the mounting hole 22, and further enhancing the waterproof performance.

[0066] In a specific embodiment, both the mounting part 23 and the grille part 24 extend along the length direction of the housing 1. The grille part 24 is provided in two sets, and the two sets of grille parts 24 are respectively arranged on both sides of the mounting part 23 along the length direction.

[0067] In one embodiment, such as Figure 5 As shown, the mounting part 23 includes a mounting groove 231, which is recessed into the housing side. The display panel 31 is mounted in the mounting groove 231. The flow-blocking edge 41 protrudes from the bottom of the mounting groove 231 and abuts against the display panel 31. Due to the abutting fit between the flow-blocking edge 41 and the display panel 31, an effective line seal or surface seal is formed at the contact surface between the flow-blocking edge 41 and the display panel 31, ensuring that external water flow is strictly isolated from the periphery of the electrical component mounting area 21 and cannot invade the internal mounting holes 22 and the display panel 32 area. This achieves waterproof protection for electronic components such as the display panel 32 with a compact and reliable structure.

[0068] In the above embodiment, by installing the display panel 31 in the mounting groove 231, the mounting groove 231 improves the assembly accuracy of the display panel 31 and provides effective circumferential limiting support for the display panel 31, preventing the display panel 31 from shifting under external force, thereby avoiding damage to the sealing interface between the display panel 31 and the baffle 41 caused by displacement, and ensuring the long-term reliability of the sealing structure.

[0069] In one embodiment, such as Figure 1 As shown, the sealing structure also includes a sealing gasket 42, which is embedded in the mounting groove 231 and surrounds the outer periphery of the flow barrier 41.

[0070] In the above embodiment, by setting a sealing gasket 42 to fill the assembly gap between the baffle 41 and the wall of the mounting groove 231, external water flow is effectively prevented from flowing into the mounting groove 231 along the edge of the display panel 31; and since the sealing gasket 42 is arranged around the outer periphery of the baffle 41, even if a small amount of external water flows through the sealing gasket 42, it will be restricted to the outer periphery of the baffle 41 and cannot penetrate into the electrical component mounting area 21 inside the baffle 41, thus further improving the waterproof level.

[0071] Preferably, a gap is provided between the flow barrier 41 and the sealing gasket 42 as a buffer area. When external water flow accidentally passes through the sealing gasket 42, the water flow will be restricted within the buffer area because the buffer area provides a buffer space for the water flow. This avoids the water flow being directly squeezed by the outer wall of the flow barrier 41 and the sealing gasket 42, thereby eliminating the risk of it seeping into the inner side of the flow barrier 41.

[0072] Preferably, the outer side of the sealing gasket 42 is in close contact with the side wall of the mounting groove 231, and the top of the sealing gasket 42 is in close contact with the bottom surface of the display panel 31.

[0073] Specifically, the sealing gasket 42 is a sponge strip.

[0074] In one embodiment, combined Figure 1 , Figure 4 as well as Figure 5 As shown, the mounting part 23 is provided with a first hole 232, and the projection of the display panel 32 in the vertical direction does not overlap with the projection of the first hole 232 in the vertical direction; and / or, the projection of the sealing structure in the vertical direction does not overlap with the projection of the first hole 232 in the vertical direction.

[0075] In the above embodiment, by providing the first hole 232, the water accumulated on the air outlet grille 2 can be drained; the projection of the display panel 32 in the vertical direction does not overlap with the projection of the first hole 232 in the vertical direction, which can ensure that the drainage path of the water on the air outlet grille 2 is completely located outside the display panel 32; the projection of the sealing structure in the vertical direction does not overlap with the projection of the first hole 232 in the vertical direction, which effectively prevents the sealing structure from blocking the drainage channel and ensures the smoothness of drainage.

[0076] In one embodiment, such as Figure 1 As shown, the display panel 31 is provided with a buckle 311, which is engaged with the first hole 232.

[0077] In the above embodiment, the display panel 31 is reliably installed and fixed by directly engaging the buckle 311 on the display panel 31 with the first hole 232; and since the buckle 311 engages with the first hole 232, there is no need to open additional penetrating mounting holes on the mounting part, which fundamentally avoids the water seepage path that may be caused by adding mounting holes, thereby maximizing the overall waterproof sealing performance.

[0078] In the above embodiment, the display panel 31 is fixed to the mounting part 23 of the air outlet grille 2 by snap-fit, forming a screwless fixation, which is convenient for disassembly and assembly.

[0079] Preferably, the display panel 31 is a strip-shaped panel, and at least two clips 311 are provided at intervals on both sides of the display panel 31 along its length; at least two locking holes are correspondingly provided on the mounting groove 231, and the at least two clips 311 are engaged with the at least two locking holes in a one-to-one manner. The engagement of the at least two clips 311 and the at least two locking holes on the air vent grille 2 can further improve the fixing effect of the display panel 31.

[0080] Preferably, the locking hole can serve as the first hole 232. After the first hole 232 is engaged with the buckle 311, there is a gap, allowing water to flow into the interior of the housing 1 through the gap.

[0081] Specifically, the display panel 32 is fixed to the air vent grille 2 by fasteners such as screws.

[0082] In one embodiment, combined Figures 6 to 9 As shown, the household appliance also includes a mainboard module 5, which is disposed inside the housing 1 and includes a mainboard bracket 51 and a mainboard 52; the mainboard bracket 51 is mounted on the air outlet grille 2; the mainboard 52 is mounted on the side of the mainboard bracket 51 away from the air outlet grille 2.

[0083] In the above embodiment, by installing the motherboard 52 on the side of the motherboard bracket 51 away from the air outlet grille 2, the flow path of the water flowing down from the air outlet grille 2 is changed, thereby ensuring that the water cannot drip directly onto the motherboard 52, providing direct waterproof protection for the motherboard 52.

[0084] Preferably, the motherboard bracket 51 is located between the motherboard 52 and the display panel 32. While changing the flow path of the water flowing down from the air outlet grille 2, it also spaces the motherboard 52 and the display panel 32 apart to avoid electromagnetic interference between them.

[0085] Preferably, the size of the display panel 32 is smaller than the size of the motherboard bracket 51. After the motherboard bracket 51 is installed on the air outlet grille 2, there is a gap between it and the air outlet grille 2. The display panel 32 is located in this gap, which can make full use of the space and improve the space utilization rate.

[0086] Preferably, the first hole 232 is located on the outer periphery of the display panel 32. The spatial arrangement fundamentally ensures that the water flow discharged from the first hole 232 is completely outside the display panel 32, thereby preventing any possibility of the water flow discharged from the first hole 232 dripping onto the surface of the display panel 32.

[0087] In some embodiments, the motherboard bracket 51 includes a groove structure formed on the side of the motherboard bracket 51 opposite to the air outlet grille 2. The motherboard 52 is embedded in the groove structure, ensuring that the motherboard bracket 51 can completely separate the motherboard 52 from the air outlet grille 2, effectively preventing any possibility of water droplets flowing down from the air outlet grille 2 falling onto the motherboard 52.

[0088] Specifically, the motherboard 52 is located in a recessed structure on the side of the motherboard bracket 51 opposite to the air outlet grille 2.

[0089] Specifically, the motherboard 52 is fixed to the motherboard bracket 51 in a groove structure on the side opposite to the air outlet grille 2 by fasteners such as screws.

[0090] Preferably, at least two supporting ribs are provided in the groove structure on the side of the motherboard bracket 51 opposite to the air outlet grille 2, and the motherboard 52 is supported and positioned on the supporting ribs. The supporting ribs can provide good support for the motherboard 52 on the one hand, and on the other hand, avoid the problem that the motherboard 52 is inconvenient to remove from the groove structure on the side of the motherboard bracket 51 opposite to the air outlet grille 2.

[0091] In some embodiments, the motherboard bracket 51 and the air vent grille 2 are connected by fasteners such as screws.

[0092] It should be noted that in this embodiment, the air outlet grille 2 is located at the top of the housing 1, the air outlet is set on the air outlet grille 2, the display panel 32 and the main board module 5 are both located inside the housing 1, the main board module 5 is the main control system of the whole machine, the main board module 5 is located below the display panel 32, while realizing waterproof protection for the main board 52, it can optimize the center of gravity of the whole machine, so that the heavier main board module 5 is placed in a lower position of the whole machine, so that the center of gravity of the whole machine is lowered and the stability of the whole machine is improved.

[0093] In one embodiment, combined Figures 6 to 9 As shown, the air outlet is set on the air outlet grille 2; the top wall of the main board bracket 51 near the air outlet grille 2 is provided with a gradually downward inclined guide slope 513. Water droplets flowing down from the air outlet grille fall on the top wall of the main board bracket 51 near the air outlet grille 2, and then flow down along the inclined guide slope 513 and drip onto the bottom wall of the housing 1, and finally flow out of the housing 1 from the second hole 11 on the bottom wall of the housing 1.

[0094] Furthermore, a water collection trough 511 is provided on the top wall of the main board bracket 51 near the air outlet grille 2, and a drain outlet 512 is provided on one side of the water collection trough 511; towards the drain outlet 512, the bottom of the water collection trough 511 gradually slopes downward to form a guide slope 513.

[0095] Furthermore, by setting a water collection trough 511 on the side of the motherboard bracket 51 near the air outlet grille 2, the water collection trough 511 first intercepts and collects the water flowing down from the air outlet grille 2, preventing the water from falling directly onto the motherboard 52 below the motherboard bracket 51; and the setting of the guide slope 513 allows the water accumulated in the water collection trough 511 to automatically converge to the drain outlet 512 and be directly discharged from the drain outlet 512, eliminating the risk of water stagnation in the water collection trough 511; through the dual action of the water collection trough 511 and the guide slope 513, the water flow range is restricted within the motherboard bracket 51, ensuring that the water flow has zero contact with the motherboard 52 and other core electronic components throughout the entire process, effectively improving the waterproof performance of household appliances.

[0096] In one embodiment, such as Figure 3 As shown, the bottom of the housing 1 is provided with a second hole 11, which is used for drainage.

[0097] In the above embodiment, by providing a second hole 11 at the bottom of the housing 1, the water flowing down from the air outlet grille 2 and the water collection tank 511 is gathered at the bottom of the housing 1 and completely discharged outside the machine through the second hole 11, thus avoiding the accumulation of water inside the housing 1.

[0098] Preferably, such as Figure 2As shown, the motherboard module 5 and the bottom wall of the housing 1 are kept at a distance, which effectively prevents water that may accumulate at the bottom of the housing 1 from rising and contacting the motherboard module 5, thereby completely avoiding the risk of the motherboard 52 being damaged by water immersion at the bottom of the housing 1.

[0099] Preferably, at least two second holes 11 are provided at the bottom of the housing 1. The at least two second holes 11 are distributed along their width and length directions to ensure that no matter where the water is generated or collected at the bottom of the housing 1, the nearest second hole 11 can be found, thereby achieving rapid and comprehensive drainage of the water inside the housing 1.
