Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to a household appliance. BACKGROUND

[0002] During use, the electric heater is likely to be used in a humid environment, and water can easily enter the interior of the electric heater through the gaps of the shell of the electric heater, thereby causing short circuit or damage of the live components (such as circuit boards, fans, heating bodies, etc.), seriously affecting the service life of the electric heater, and even causing fire or electric shock accidents. SUMMARY

[0003] Therefore, the present application provides a household appliance to solve the problem of poor waterproof effect of the electric heater.

[0004] The present application provides a household appliance, comprising:

[0005] a shell;

[0006] an air outlet grille mounted on the shell, the air outlet grille being 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 an assembly hole;

[0007] a display module, comprising a display panel mounted on the outer side of the air outlet grille, and a display plate provided on the inner side of the air outlet grille corresponding to the electrical component mounting area; the display plate at least partially penetrates the assembly hole;

[0008] a sealing structure is sealingly arranged 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 sealingly arranging the sealing structure between the display panel and the air outlet grille, and arranging the sealing structure around the outer periphery of the electrical component mounting area, the external water flow can be effectively blocked from penetrating into the electrical component mounting area along the joint between the display panel and the grille. The external water flow is blocked by the sealing structure outside the electrical component mounting area, and cannot directly contact or flow to the assembly hole of the internal electrical component mounting area, thereby isolating the path of the external water flow invading the display plate and other electronic components, 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.

[0010] In an alternative embodiment, the air outlet grille comprises 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 comprises a flow-blocking surrounding edge, which is arranged around the outer periphery of the electrical component mounting area and protrudes from the side wall surface of the mounting portion away from the shell.

[0012] Beneficial effects: Since the flow-blocking surrounding edge is arranged around the outer circumferential side of the electrical component mounting area and protrudes from the mounting portion to the side wall of the housing, the height of the external water flow entering the electrical component mounting area is raised, and a waterproof barrier is formed around the outer periphery of the electrical component mounting area.

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

[0014] Beneficial effects: By mounting the display panel in the mounting groove, the assembly precision of the display panel is improved by the arrangement of the mounting groove, and effective circumferential limiting support is provided for the display panel, preventing displacement of the display panel under external force, thereby avoiding damage to the sealing interface between the display panel and the flow-blocking surrounding edge due to displacement, and ensuring long-term reliability of the sealing structure. Moreover, since the flow-blocking surrounding edge abuts against the display panel, effective linear sealing or surface sealing is formed at the contact surface between the flow-blocking surrounding edge and the display panel, ensuring that the external water flow is strictly isolated outside the electrical component mounting area and cannot invade the internal assembly hole and the display panel area, thereby achieving waterproof protection of the display panel and other electronic components in a compact and reliable structure.

[0015] In an optional embodiment, the sealing structure further comprises:

[0016] a sealing gasket, which is embedded in the mounting groove and arranged around the outer periphery of the flow-blocking surrounding edge.

[0017] Beneficial effects: By arranging the sealing gasket to fill the assembly gap between the outer circumferential side of the flow-blocking surrounding edge and the groove wall of the mounting groove, the external water flow flowing along the edge of the display panel into the interior of the mounting groove is effectively blocked; and since the sealing gasket is arranged around the outer periphery of the flow-blocking surrounding edge, even if a small amount of external water flow passes through the sealing gasket, it will be limited to the outer circumferential side of the flow-blocking surrounding edge and cannot penetrate into the electrical component mounting area inside the flow-blocking surrounding edge, further improving the waterproof level.

[0018] In an 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 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 the projection of the first hole in the vertical direction.

[0019] Beneficial effects: by setting the first hole, the accumulated water on the air outlet grille can be drained; 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, which can ensure that the drainage path of the water accumulated on the air outlet grille is completely located outside the display panel; the projection of the sealing structure in the vertical direction does not overlap with the projection of the first hole in the vertical direction, which effectively prevents the sealing structure from blocking the drainage channel and ensures the smoothness of drainage.

[0020] In an optional embodiment, a buckle is arranged on the display panel, and the buckle is connected with the first hole.

[0021] Beneficial effects: by directly connecting the buckle on the display panel with the first hole, reliable installation and fixation of the display panel are achieved; and since the buckle is connected with the first hole, no additional penetrating installation hole needs to be arranged on the installation part, which fundamentally avoids the water seepage path caused by the additional installation hole, thereby maximizing the overall waterproof sealing performance.

[0022] In an optional embodiment, a mainboard module is further included, which is arranged in the shell and includes:

[0023] A mainboard support is installed on the air outlet grille.

[0024] A mainboard is installed on the side of the mainboard support away from the air outlet grille.

[0025] Beneficial effects: by installing the mainboard on the side of the mainboard support away from the air outlet grille, the falling path of the water flowing from the air outlet grille is blocked, thereby ensuring that the water cannot directly drip onto the mainboard and providing direct waterproof protection for the mainboard.

[0026] In an optional embodiment, a gradually downward inclined water guide slope is arranged on the top wall of the side of the mainboard support close to the air outlet grille.

[0027] In an optional embodiment, a water collecting groove is arranged on the top wall of the side of the mainboard support close to the air outlet grille, and a drainage opening is arranged on one side of the water collecting groove.

[0028] The groove bottom of the water collecting groove gradually inclines downward to form a water guide slope towards the direction close to the drainage opening.

[0029] Beneficial effects: By setting a water collection tank on the side of the mainboard bracket close to the air outlet grille, the water collection tank first intercepts and collects the water flowing down from the air outlet grille to prevent the water from falling directly onto the mainboard below the mainboard bracket; and the setting of the diversion slope makes the water accumulated in the water collection tank automatically converge to the drain outlet and be directly discharged from the drain outlet, eliminating the risk of water accumulation in the water collection tank; through the dual effects of the water collection tank and the diversion slope, the range of water flow is limited to the mainboard bracket, ensuring that the water flow has zero contact with the mainboard and other core electronic components throughout the process, effectively improving the waterproof performance of household appliances.

[0030] In an optional embodiment, a second hole is provided at the bottom of the shell, and the second hole is used for drainage.

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

[0032] In an optional embodiment, the household appliance is an electric heater. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application.

In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0053] ​In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0054] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0055] The following combination Figures 1 to 9 , describing embodiments of the present invention.

[0056] According to an embodiment of the present invention, Figures 1 to 9 As shown, the present invention provides a household appliance, comprising a housing 1, an air outlet grille 2, a display module, and a sealing structure. The air outlet grille 2 is mounted on the housing 1 and is provided with an air outlet. The air outlet grille 2 is provided with an electrical component mounting area 21, and the electrical component mounting area 21 is provided with an assembly hole 22. The display module includes a display panel 31 mounted on the outside of the air outlet grille 2, and a display board 32 disposed on the inside of the air outlet grille 2 corresponding to the electrical component mounting area 21. The assembly hole 22 is at least large enough for a pressure control spring between the display board 32 and the display panel 31 to pass through. The sealing structure is sealed between the display panel 31 and the air outlet 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 the center of the electrical component mounting area 21. The outer side of the air outlet grille refers to the side of the air outlet grille facing away from the interior of the housing 1; the inner side of the air outlet grille 2 refers to the side of the air outlet grille 2 facing the interior of the housing 1.

[0057] In the above embodiment, 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. This effectively prevents external water from penetrating 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 electrical component mounting area 21. This prevents external water from invading 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 embodiment, the electrical component installation area 21 is an area on the air outlet grille 2 that is opposite to the display panel 32 .

[0059] In a specific embodiment, the display panel 32 integrates the pressing control spring, the display screen, the remote control sensing piece, and the electronic components such as the capacitor, the resistor, and the inductor; and the display panel 31 contains the control button and the transparent window. The assembly hole 22 includes the connecting hole 221, the clearance hole 222, the display port 223, and the through hole 224: wherein the pressing control spring passes through the connecting hole 221 to link with the control button on the display panel 31, realizing the physical key feedback; the display screen projects the displayed information data to the transparent window of the display panel 31 through the display port 223, ensuring that the user can clearly read the data; the capacitor, the resistor, and the inductor correspond to one clearance hole 222 respectively when installed, avoiding the structural interference between the capacitor, the resistor, and the inductor and the air outlet grille 2 through the space avoidance of the clearance hole 222; the remote control sensing piece is aligned with the through hole 224, which can form a signal channel to ensure that the instructions of the external remote controller and other devices can be sensed and received by the remote control sensing piece, in addition to avoiding the structural interference between the remote control sensing piece and the air outlet grille 2 through the space avoidance when the display panel 32 is installed.

[0060] Specifically, the connecting hole 221 can be configured as a circular hole, which is adapted to the shape of the pressing control spring; the clearance hole 222 can be configured as a square hole, which is adapted to the shape of the capacitor, the resistor, and the inductor; the display port 223 can be configured as a square port, which is adapted to the shape of the display screen; and the through hole 224 can be configured as a square hole, which is adapted to the shape of the remote control sensing piece.

[0061] It should be noted that in the present embodiment, the household appliance includes but is not limited to the air purifier, the air conditioner, the humidifier, and the electric heater. Preferably, the household appliance is the electric heater. As shown in Figure 2 The inside of the electric heater can include the humidifying assembly 6, the heating body assembly 7, and the circuit board assembly. The circuit board assembly includes the mainboard module 5 and the display panel 32. Since the mainboard module 5 and the display panel 32 are both located in the closed space formed inside the shell 1, it is necessary to avoid the water flow from the upper part of the shell 1 from invading the inside of the shell 1 and contacting the key electrical components such as the mainboard module 5 and the display panel 32.

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

[0063] In one embodiment, in combination with 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 flow-blocking edge 41, which is arranged around the outer peripheral side of the electrical component mounting area 21 and protrudes from the side wall of the mounting portion 23 away from the shell 1.

[0064] In the above embodiment, because the flow-blocking edge 41 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, it increases the height at which external water flows into the electrical component mounting area 21, forming a waterproof barrier around the 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 intrude into the internal assembly holes 22 and the display panel 32 area, thus 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 wall surface on one side of the mounting portion 23 away from the housing 1, and the flange is arranged around the outer periphery of the assembly hole 22. Even if external water flows into the inner side of the flow-blocking edge 41, the flange can effectively prevent the water from flowing further toward the assembly hole 22, thereby isolating the possibility of water flowing through the assembly hole 22 and invading the internal display panel 32 and other electronic components, further enhancing the waterproof performance.

[0066] In a specific embodiment, both the mounting portion 23 and the grille portion 24 extend along the length direction of the housing 1 . Two groups of grille portions 24 are provided, and the two groups of grille portions 24 are respectively arranged on both sides of the mounting portion 23 along the length direction.

[0067] In one embodiment, Figure 5 As shown, the mounting portion 23 includes a mounting groove 231, which is formed by recessing the mounting portion 23 toward one side of the housing. The display panel 31 is mounted within 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. This abutment between the flow-blocking edge 41 and the display panel 31 creates an effective line seal or surface seal at the interface between the flow-blocking edge 41 and the display panel 31, ensuring that external water flow is strictly isolated to the periphery of the electrical component mounting area 21 and prevented from invading the internal assembly holes 22 and the display panel 32 area. This compact and reliable structure provides waterproof protection for electronic components such as the display panel 32.

[0068] In the above embodiment, by installing the display panel 31 in the installation groove 231, the installation 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 being displaced under external force, thereby avoiding damage to the sealing interface between the display panel 31 and the flow-blocking surrounding edge 41 caused by displacement, and ensuring the long-term reliability of the sealing structure.

[0069] In one embodiment, as shown in Figure 1 , the sealing structure further includes a sealing gasket 42, which is embedded in the installation groove 231 and arranged around the outer periphery of the flow-blocking surrounding edge 41.

[0070] In the above embodiment, by filling the assembly gap between the flow-blocking surrounding edge 41 and the groove wall of the installation groove 231 with the sealing gasket 42, external water flow is effectively blocked from flowing into the interior of the installation groove 231 along the edge of the display panel 31; and since the sealing gasket 42 is arranged around the outer periphery of the flow-blocking surrounding edge 41, even if a small amount of external water flow passes through the sealing gasket 42, it will be limited to the outer periphery side of the flow-blocking surrounding edge 41 and cannot penetrate into the electrical component mounting area 21 inside the flow-blocking surrounding edge 41, further improving the waterproof level.

[0071] Preferably, a gap is provided between the flow-blocking surrounding edge 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 limited in the buffer area due to the buffer space provided by the buffer area, avoiding the risk of water flow penetrating into the inside of the flow-blocking surrounding edge 41 due to direct extrusion by the outer side wall of the flow-blocking surrounding edge 41 and the sealing gasket 42.

[0072] Preferably, the outer side of the sealing gasket 42 tightly abuts against the side wall of the installation groove 231, and the top end of the sealing gasket 42 tightly abuts against the bottom surface of the display panel 31.

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

[0074] In one embodiment, as shown in Figure 1 , Figure 4 and Figure 5 , the first hole 232 is provided on the mounting portion 23, and the projection of the display panel 32 in the vertical direction does not overlap 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 the projection of the first hole 232 in the vertical direction.

[0075] In the above embodiment, by arranging the first hole 232, the accumulated water on the air outlet grille 2 can be drained; the projection of the display panel 32 in the vertical direction does not overlap the projection of the first hole 232 in the vertical direction, which can ensure that the water drainage path of the water accumulated on the air outlet grille 2 is completely located at the periphery of the display panel 32; the projection of the sealing structure in the vertical direction does not overlap 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 the drainage.

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

[0077] In the above embodiment, the buckle 311 on the display panel 31 directly connects with the first hole 232, which realizes reliable installation and fixation of the display panel 31; and since the buckle 311 connects with the first hole 232, there is no need to additionally arrange a penetrating installation hole on the installation part, which fundamentally avoids the water seepage path caused by the additional installation hole, thereby maximizing the overall waterproof sealing performance.

[0078] In the above embodiment, the display panel 31 is fixed on the installation part 23 of the air outlet grille 2 by the connection mode, which forms a screw-free fixation and facilitates disassembly and assembly.

[0079] Preferably, the display panel 31 is a strip-shaped panel, and at least two buckles 311 are arranged on both sides of the display panel 31 along the length direction; at least two buckle holes are correspondingly arranged on the installation groove 231, and the at least two buckles 311 are connected with the at least two buckle holes one by one. The cooperation of the at least two buckles 311 and the at least two buckle holes on the air outlet grille 2 can further improve the fixation effect of the display panel 31.

[0080] Preferably, the buckle hole can be used as the first hole 232. After the first hole 232 connects with the buckle 311, there is a gap, and water can flow into the inside of the shell 1 from the gap.

[0081] Specifically, the display panel 32 is fixed on the air outlet grille 2 by a screw or other fastener.

[0082] In one embodiment, as shown in Figures 6 to 9 The household appliance further comprises a mainboard module 5, which is arranged in the shell 1 and comprises a mainboard support 51 and a mainboard 52; the mainboard support 51 is installed on the air outlet grille 2; and the mainboard 52 is installed on the side of the mainboard support 51 away from the air outlet grille 2.

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

[0084] Preferably, the main board support 51 is located between the main board 52 and the display panel 32, and the main board 52 and the display panel 32 are spaced apart while changing the flow path of the water flowing from the air outlet grille 2, thereby avoiding electromagnetic interference between the two.

[0085] Preferably, the size of the display panel 32 is smaller than the size of the main board support 51, and the main board support 51 has a spacing space between the main board support 51 and the air outlet grille 2 after being installed on the air outlet grille 2, and the display panel 32 is located in the spacing space, which can fully utilize the space and improve the space utilization.

[0086] Preferably, the first hole 232 is located on the outer circumferential side of the display panel 32, and the spatial layout fundamentally ensures that the water flow discharged from the first hole 232 is completely located outside the display panel 32, thereby isolating 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 main board support 51 comprises a groove structure formed on the side of the main board support 51 away from the air outlet grille 2, and the main board 52 is embedded and installed in the groove structure, so that the main board support 51 can completely separate the main board 52 from the air outlet grille 2, effectively isolating any possibility of water flowing from the air outlet grille 2 dripping onto the main board 52.

[0088] Specifically, the main board 52 is arranged in the groove structure on the side of the main board support 51 away from the air outlet grille 2.

[0089] Specifically, the main board 52 is fixed in the groove structure on the side of the main board support 51 away from the air outlet grille 2 by screws or other fasteners.

[0090] Preferably, at least two supporting ribs are arranged in the groove structure on the side of the main board support 51 away from the air outlet grille 2, and the main board 52 is supported and positioned on the supporting ribs. The supporting ribs can not only provide good support for the main board 52, but also avoid the problem of the main board 52 being difficult to remove from the groove bottom of the groove structure on the side of the main board support 51 away from the air outlet grille 2.

[0091] In some embodiments, the main board support 51 and the air outlet grille 2 are connected by screws or other fasteners.

[0092] It should be noted that in the embodiment, the air outlet grille 2 is located at the top of the shell 1, the air outlet is arranged on the air outlet grille 2, the display panel 32 and the mainboard module 5 are located inside the shell 1, the mainboard module 5 is the main control system of the whole machine, and the mainboard module 5 is located below the display panel 32. While realizing waterproof protection of the mainboard 52, the gravity center of the whole machine can be optimized, so that the relatively heavy mainboard module 5 is arranged at the lower position of the whole machine, the gravity center of the whole machine is lowered as a whole, and the stability of the whole machine is improved.

[0093] In one embodiment, in combination with Figures 6 to 9 As shown in the figure, the air outlet is arranged on the air outlet grille 2; the top wall of the mainboard support 51 close to one side of the air outlet grille 2 is provided with a gradually downward inclined flow guide slope 513. After the water droplets flowing down from the air outlet grille fall on the top wall of the mainboard support 51 close to one side of the air outlet grille 2, the water droplets flow down along the inclined flow guide slope 513 and then fall on the bottom wall of the shell 1, and finally flow out of the shell 1 from the second hole 11 in the bottom wall of the shell 1.

[0094] Further, the top wall of the mainboard support 51 close to one side of the air outlet grille 2 is provided with a water collecting groove 511, and one side of the water collecting groove 511 is provided with a water outlet 512; towards the direction close to the water outlet 512, the groove bottom of the water collecting groove 511 is gradually inclined to form the flow guide slope 513.

[0095] Further, by arranging the water collecting groove 511 on the side of the mainboard support 51 close to the air outlet grille 2, the water collecting groove 511 first intercepts and collects the water flowing down from the air outlet grille 2, so as to avoid the water flowing directly to the mainboard 52 below the mainboard support 51; and the arrangement of the flow guide slope 513 enables the water accumulated in the water collecting groove 511 to automatically converge to the water outlet 512 and be directly discharged from the water outlet 512, thereby eliminating the risk of water stagnation in the water collecting groove 511; through the double action of the water collecting groove 511 and the flow guide slope 513, the water flow range is limited in the mainboard support 51, so as to ensure that the water flow is in zero contact with the core electronic components such as the mainboard 52 throughout the whole process, and the waterproof performance of the household appliance is effectively improved.

[0096] In one embodiment, as Figure 3 As shown in the figure, the bottom of the shell 1 is provided with a second hole 11, and the second hole 11 is used for water drainage.

[0097] In the above embodiment, by arranging the second hole 11 in the bottom of the shell 1, the water flowing down from the air outlet grille 2 and the water collecting groove 511 converges to the bottom of the shell 1 and is completely discharged outside the machine through the second hole 11, so as to avoid the accumulation of water flow inside the shell 1.

[0098] Preferably, as Figure 2As shown, the mainboard module 5 is arranged in a spaced manner between the bottom wall of the shell 1, effectively preventing the water accumulated at the bottom of the shell 1 from rising to contact the mainboard module 5, thereby completely avoiding the risk of damage to the mainboard 52 due to immersion in the accumulated water at the bottom of the shell 1.

[0099] Preferably, at least two second holes 11 are arranged at the bottom of the shell 1, and the at least two second holes 11 are arranged in a distributed manner along the width direction and the length direction thereof, ensuring that no matter where the accumulated water is generated or gathered at the bottom of the shell 1, the adjacent second hole 11 can be found, thereby achieving rapid and comprehensive drainage of the accumulated water in the shell 1.

[0100] In one embodiment, the household appliance is an electric heater.

[0101] It should be noted that in the present embodiment, the household appliance includes but is not limited to an air purifier, an air conditioner, a humidifier, and an electric heater. Preferably, the household appliance is an electric heater.

[0102] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the appended claims.
