Description

Technical Field

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

[0002] With technological advancements, home appliances now commonly integrate user operation modules to achieve intelligent configuration and significantly enhance the human-computer interaction experience. These modules not only make operation more convenient but also improve equipment efficiency and user satisfaction through intelligent functions. Taking washer-dryers as an example, their user operation modules have become the core component connecting users to the equipment's functions, playing a crucial role in enhancing the user experience.

[0003] However, in practical applications, to ensure user safety and extend the lifespan of internal electronic modules, the casing of the user operating module typically needs to be waterproof and dustproof. However, commonly used engineering plastics are highly hygroscopic and easily absorb water molecules from humid air during daily use or storage. When the washer-dryer is running its drying cycle, the increased temperature causes water molecules in the plastic components to evaporate and enter the sealed space inside the user operating module casing. If the plastic components are completely sealed, these water molecules will condense into small water droplets in areas with relatively lower temperatures, such as the user interface. This not only interferes with normal user operation but may also corrode internal electronic components, thus affecting the overall performance and lifespan of the equipment. Utility Model Content

[0004] One objective of this utility model is to provide an improved household appliance.

[0005] Therefore, this utility model embodiment provides a household appliance, including: a body including a heating module; a housing disposed on the body and receiving at least a portion of the heat emitted by the heating module, the housing having an outwardly opening window; a display and / or input unit located within the housing, the window exposing at least a portion of the display and / or input unit; a cover plate covering the window on the outward-facing side of the housing; and further including: an exhaust channel disposed between the cover plate and the housing, the exhaust channel being used to connect the window to the outside, the outlet of the exhaust channel being located below the highest point of the exhaust channel.

[0006] Therefore, the exhaust channel located between the cover and the housing can connect the window to the outside, allowing water vapor to escape smoothly. This effectively prevents water vapor from accumulating inside the housing, thus preventing water vapor condensation from interfering with normal operation and corroding internal electronic components, ensuring normal equipment operation and a good user experience. Furthermore, the exhaust outlet is located below the highest point of the exhaust channel, which can prevent external water from entering the housing to a certain extent, providing additional protection for the internal electronic components and further improving the reliability and stability of the equipment.

[0007] Optionally, at least a portion of the exhaust channel forms a water-tight structure between the outside and the window. This ensures that water vapor can be smoothly discharged through the exhaust channel while effectively preventing external moisture from entering the housing. This helps protect internal electronic components from external moisture interference, avoiding damage caused by moisture ingress and thus ensuring the normal operation of the equipment.

[0008] Optionally, the outlet is formed in the housing or the cover plate, and is disposed adjacent to at least one of the left and right sides of the cover plate in the horizontal direction. Thus, the outlet disposed adjacent to the side of the cover plate is more concealed, which helps to achieve a seamless and consistent appearance of the household appliance.

[0009] Optionally, the outlet is located adjacent to the lower side of the cover plate along the direction of gravity. This makes the outlet more concealed, contributing to a more integrated and consistent appearance of the household appliance. Simultaneously, under the influence of gravity, water is less likely to enter the housing through the exhaust channel, resulting in better waterproofing of the housing.

[0010] Optionally, the height difference between the highest point of the exhaust channel and the outlet is within a preset range. This prevents water outside the household appliance from rising to the highest point of the exhaust channel due to capillary action and entering the housing, thus avoiding damage to the device.

[0011] Optionally, the exhaust passage includes: a first section, one end of which is connected to the outside; and a second section, which is connected to the other end of the first section and directly or indirectly connected to the window, wherein there is a non-zero angle between the extending direction of the second section and the extending direction of the first section. Thus, the angle between the first section and the second section can create a labyrinthine structure in the exhaust passage, further enhancing the sealing effect.

[0012] Optionally, the outlet is located adjacent to at least one of the left and right sides of the cover plate along the horizontal direction, with the first section extending horizontally and the second section extending in the opposite direction of gravity. This allows for a simple and effective formation of a sealing exhaust channel.

[0013] Optionally, the length of the second segment extending in the opposite direction of gravity is within a preset range, which is related to the cross-sectional area of ​​the segment extending in the opposite direction of gravity perpendicular to the direction of gravity. Thus, a suitable combination of length and cross-sectional area can effectively prevent external water from entering the housing through the venting channel.

[0014] Optionally, the preset range is 3-20 mm. Therefore, within this range, the exhaust channel can meet the requirements for water vapor discharge while also reducing the area occupied by the exhaust channel, which helps improve the space utilization of household appliances and achieve miniaturized design.

[0015] Optionally, the exhaust channel further includes a third section connecting the second section and the window. Thus, the third section, as a connecting transition between the window and the second section, better guides water vapor into the exhaust channel, reduces flow resistance, and improves exhaust efficiency. The third section also further improves the exhaust channel structure, helping to better prevent external water from entering the exhaust channel.

[0016] Optionally, the household appliance further includes a sealing structure disposed around the window, the sealing structure contacting both the cover and the housing, the sealing structure forming at least a portion of the boundary of the exhaust channel. Thus, while ensuring the exhaust and waterproofing functions of the exhaust channel, the sealing structure's sealing properties effectively prevent external moisture and impurities from entering the housing.

[0017] Optionally, the household appliance further includes: a rib extending from the receiving housing toward the cover plate, the cover plate being supported by the rib, and the rib forming at least a portion of the boundary of the exhaust channel. Thus, the rib structure serves to support the cover plate and also as the boundary of the exhaust channel, simplifying the structure and reducing manufacturing costs.

[0018] Optionally, the housing has an edge surrounding the window for mounting the cover plate, and the exhaust channel is formed along the edge. Thus, the edge provides a platform for the exhaust channel, making the structure and layout of the housing more rational.

[0019] Optionally, a groove is formed on the edge, recessed in a direction away from the cover plate, the groove defining at least a portion of the boundary of the exhaust channel. Thus, by creating a groove, the cross-sectional area of ​​the exhaust channel can be further increased, ensuring smooth discharge of water vapor and reducing the height difference between the highest point of the required exhaust channel and the outlet, avoiding structural difficulties in meeting dimensional requirements.

[0020] Optionally, the height difference between the highest point of the exhaust channel and the outlet is calculated using the Lorentz formula. Therefore, using a scientific formula to calculate the height difference makes the exhaust channel design more scientific and rational.

[0021] Optionally, the heating module includes a drying module, with the housing disposed adjacent to the drying module. This effectively solves the problem of water vapor generation within the housing due to heat generated during the drying process, ensuring the stability and reliability of the display and / or input unit during the drying function operation.

Detailed Implementation

[0029] As mentioned in the background section, in existing household appliances, small water droplets tend to condense on areas such as the user interface where the temperature is relatively low. This not only interferes with the user's normal operation but may also corrode internal electronic components, thereby affecting the overall performance and lifespan of the device.

[0030] To solve the above-mentioned technical problems, this utility model provides a household appliance, including: a body including a heating module; a housing disposed in the body and receiving at least a portion of the heat emitted by the heating module, the housing having an outwardly opening window; a display and / or input unit located within the housing, the window exposing at least a portion of the display and / or input unit; a cover plate covering the window on the outward-facing side of the housing; and further including: an exhaust channel disposed between the cover plate and the housing, the exhaust channel connecting the window to the outside, the outlet of the exhaust channel being located below the highest point of the exhaust channel.

[0031] Therefore, the exhaust channel located between the cover and the housing can connect the window to the outside, allowing water vapor to escape smoothly. This effectively prevents water vapor from accumulating inside the housing, thus preventing water vapor condensation from interfering with normal operation and corroding internal electronic components, ensuring normal equipment operation and a good user experience. Furthermore, the exhaust outlet is located below the highest point of the exhaust channel, which can prevent external water from entering the housing to a certain extent, providing additional protection for the internal electronic components and further improving the reliability and stability of the equipment.

[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0033] Figure 1 This is a schematic diagram of a household appliance 100 according to an embodiment of the present utility model. Figure 2 yes Figure 1 A schematic diagram of the structure in region A. Figure 3 yes Figure 2 Exploded view of the structure shown. Figure 4 yes Figure 3 A magnified view of a portion of region B in the middle.

[0034] Combination Figures 1 to 4 The household appliance 100 may include: a body 10, including a heating module 101; a housing 1, disposed on the body 10 and receiving at least a portion of the heat emitted by the heating module 101, the housing 1 having an outwardly opening window 11; a display and / or input unit 2, located inside the housing 1, the window 11 exposing at least a portion of the display and / or input unit 2; a cover 3, covering the window 11 on the outward-facing side of the housing 1; and further includes: an exhaust channel 4, disposed between the cover 3 and the housing 1, the exhaust channel 4 connecting the window 11 to the outside, the outlet 41 of the exhaust channel 4 being located below the highest point 42 of the exhaust channel 4.

[0035] The household appliance 100 described in this embodiment may integrate electrical components and may operate in a humid environment. For example, the household appliance 100 may include a washing machine, washer-dryer, dryer, etc.

[0036] Specifically, refer to Figure 1 The household appliance 100 described in this embodiment may include a body 10. In some embodiments, the body 10 may include a drum 30 for holding objects to be washed and / or dried. Furthermore, the body 10 may also be provided with a detergent dispenser 20 for dispensing detergent into the drum 30. The detergent dispenser 20 may be, for example, a drawer-type dispenser.

[0037] Furthermore, the household appliance 100 may also include a heating module 101.

[0038] In some embodiments, the heating module 101 may be, for example, a drying module to enable the drying function of the household appliance 100.

[0039] In other embodiments, the heating module 101 may also be, for example, a temperature regulation module that can heat the washing water to different temperatures to achieve different washing functions.

[0040] For ease of description, in this embodiment, the width direction of the household appliance 100 is denoted as the x-direction, the depth direction as the y-direction, and the height direction as the z-direction. In this embodiment, the front and back directions refer to the y-direction and its opposite. Specifically, front or front side refers to the direction in which the household appliance 1 faces the user when in use, and rear or rear side refers to the direction in which the household appliance 1 is away from the user when in use.

[0041] In some embodiments, the roller 30 may have a forward-facing opening for a user to place or retrieve objects into the roller 30. In some embodiments, the feed box 20 may move along the y-direction toward or away from the body 10 to be pulled out or pushed back into the body 10.

[0042] Furthermore, combined with Figures 1 to 3 The household appliance 100 may also include a housing 1 and an outwardly opening window 11 disposed on the body 10. For example, the housing 1 may be disposed side by side with the feeding box 20 above the roller 30 along the x-direction. In this example, the outwardly opening window 11 can be understood as a forward-opening window 11.

[0043] In some embodiments, the housing 1 may further include a front housing 13 and a rear housing 14. The window 11 is formed in the front housing 13. The front housing 13 and the rear housing 14 are detachably connected to facilitate the assembly and disassembly of the housing 1.

[0044] Furthermore, the home appliance 1 may also include a display and / or input unit 2. The display and / or input unit 2 may include a user interface module (UIM) for displaying the setting parameters or status of the home appliance 100 and / or receiving control commands input by the user.

[0045] In some embodiments, the housing 1 is adapted to form a receiving space for accommodating the display and / or input unit 2, the display and / or input unit being located within the receiving space, and the window 11 exposing at least a portion of the display and / or input unit 2.

[0046] Further reference Figure 1 and Figure 2 The household appliance 100 may also include a cover 3 for closing the window 11. After the display and / or input unit 2 is placed in the housing 1, the cover 3 can close the window 11 to enclose the display and / or input unit 2 within the housing 1.

[0047] In some embodiments, the cover plate 3 may be made of a transparent or translucent material so that the content displayed on the display and / or input unit 2 is visible to the outside through the cover plate. For example, the cover plate 3 may be a PMMA (Polymethyl Methacrylate, also known as "acrylic" or "plexiglass") panel.

[0048] In some embodiments, the cover plate 3 may have touch interaction functionality, so that the display and / or input unit 2 can receive input signals input by the user via the touch cover plate 3. For example, at least a portion of the cover plate 3 may be a touch panel.

[0049] In some embodiments, the cover plate 3 may be provided with function keys such as knobs and buttons, so that the display and / or input unit 2 can receive input signals input by the user via the operation of the function keys. In a variation, the function keys may be located at other positions on the body 10, such as between the feeding box 20 and the cover plate 3.

[0050] Furthermore, an exhaust channel 4 is disposed between the cover plate 3 and the housing 1. The exhaust channel 4 is used to connect the window 11 to the outside to discharge the water vapor accumulated inside the housing 1.

[0051] In this embodiment, the housing 1 is positioned adjacent to the drying module forming the heating module 101. In practical applications, when the household appliance 100 performs functions such as drying, the temperature inside the housing 1 will rise, the temperature of the air inside will also rise, and the volume of the air will increase accordingly. After the pressure inside the housing 1 increases, the high-temperature air containing water vapor can escape from the exhaust channel 4, preventing water vapor from condensing into water droplets at the cover plate 3, interfering with user operation, or even corroding electronic components.

[0052] Furthermore, the outlet 41 of the exhaust passage 4 is located below the highest point 42 of the exhaust passage 4. Air in the exhaust passage 4 is discharged to the outside through the outlet 41.

[0053] As described above, the exhaust channel 4 located between the cover plate 3 and the housing 1 connects the window 11 to the outside. Water vapor can be smoothly discharged through the exhaust channel 4, effectively preventing water vapor from accumulating inside the housing 1. This prevents water vapor from condensing into small water droplets, which could interfere with normal user operation or corrode internal electronic components, ensuring normal equipment operation and a good user experience. Furthermore, the outlet 41 of the exhaust channel 4 is located below the highest point 42 of the exhaust channel 4, which can prevent external water from entering the housing 1 to a certain extent, providing additional protection for the internal electronic components and further improving the reliability and stability of the equipment.

[0054] In some embodiments, at least a portion of the exhaust passage 4 forms a water-tight structure from the outside to the window 11. The water-tight structure may be formed by at least a portion of the section between the outlet 41 of the exhaust passage 4 and the highest point 42 of the exhaust passage 4.

[0055] In practical applications, in high-humidity environments (such as laundry rooms) or when water splashes on the surface of household appliances 100, external moisture may enter window 11 through exhaust channel 4. The water-sealed structure formed by at least a portion of exhaust channel 4 can inhibit liquid water penetration through physical barriers or capillary action, protecting the display and / or input unit 2 from the risk of short circuits or corrosion.

[0056] It should be understood that the water-sealed structure is only for liquid water and has minimal blocking effect on water vapor molecules (approximately 0.0004 μm in diameter). The remaining sections of the exhaust channel 4 remain open to ensure that the internal hot and humid air can be discharged smoothly. For example, during the drying process of a washer-dryer (or dryer), internal water vapor can be discharged through the exhaust channel 4, while external splashes or condensation are effectively blocked, thus achieving "one-way dehumidification".

[0057] In some embodiments, the exhaust channel 4 may have a labyrinth structure, thereby providing a certain sealing effect and preventing foreign objects from the external environment from easily entering the housing 1 through the exhaust channel 4.

[0058] In some embodiments, the opening area of ​​the outlet 41 may be smaller than the cross-sectional area of ​​the exhaust channel 4 to further prevent foreign objects from the external environment from entering the exhaust channel 4 or even the housing 1 from the outlet 41.

[0059] In some embodiments, the outlet 41 may be formed on the housing 1 or the cover 3, and disposed adjacent to at least one of the left and right sides of the cover 3 in the horizontal direction. Thus, the outlet disposed adjacent to the side of the housing 1 or the cover 3 is more concealed, which helps to achieve the overall integrity and consistency of the appearance of the household appliance 100.

[0060] In some embodiments, the outlet 41 may also be located adjacent to the lower side of the cover plate 3 along the direction of gravity (e.g., the opposite direction of the z-direction). Thus, the outlet 41 located adjacent to the side of the cover plate 3 is more concealed, which is beneficial to achieving the overall integrity and consistency of the appearance of the household appliance 100; at the same time, under the action of gravity, water is less likely to enter the housing 1 along the exhaust channel 4, and the waterproof effect of the housing 1 is better.

[0061] In some embodiments, the height difference between the highest point 42 of the exhaust channel 4 and the outlet 41 is within a preset range. This prevents water outside the household appliance 100 from rising to the highest point 42 of the exhaust channel 4 under capillary action and entering the housing 1, thus avoiding damage to the device.

[0062] In some embodiments, the value of the height difference is related to the cross-sectional area of ​​the section of the exhaust passage 4 that has an equivalent extension length relative to the outlet 41 in the opposite direction of gravity (e.g., the z-direction) in the direction perpendicular to gravity.

[0063] In some embodiments, the height difference between the highest point 42 of the exhaust passage 4 and the outlet 41 is calculated according to the Lorentz formula.

[0064] For example, in a specific application scenario, combined with Figure 4 and Figure 5 Because the overall size of the exhaust channel 4 is relatively small, it is prone to a siphon effect on water. Therefore, the width, height, and depth of the exhaust channel 4 need to be specially designed to ensure that the rise height h of external water within the exhaust channel 4 does not exceed the total height H of the exhaust channel 4, thereby achieving a water seal. The total height H of the exhaust channel 4 can be characterized by the height difference between the highest point 42 of the exhaust channel 4 and the outlet 41.

[0065] Specifically, the Lorentz equation can be used to calculate the rise height h of water in a capillary tube:

[0066]

[0067] in, Let θ be the contact angle between the liquid and the solid, and r be the interfacial tension between the liquid and the solid surfaces. Let g be the liquid density, g be the gravitational acceleration, and R be the capillary radius.

[0068] Taking a washer-dryer as an example of household appliance 100, the liquid can be either water or detergent solution. The surface tension of the detergent solution is approximately 70 mN / m; the contact angle is approximately 30°; converting the cross-sectional area of ​​the exhaust channel 4 to its radius, it is approximately 0.87 mm; the cross-sectional area of ​​the exhaust channel 4 can be approximately calculated by multiplying its depth D and width w. Therefore, the climbing height h can be calculated to be approximately 14 mm. If the climbing height is estimated based on water, it will be even smaller. Therefore, in this case, the total height H of the exhaust channel 4 is designed to be greater than 14 mm.

[0069] In some embodiments, the depth D of the exhaust channel 4 can be taken from [1, 2] mm, depending on the wall thickness of the part and the internal space constraints; considering the space constraints in practical applications and the sealing requirements of the component, the width w of the exhaust channel 4 can be taken from [2, 10] mm.

[0070] According to the Lorentz equation above, the smaller the cross-sectional area of ​​the exhaust passage 4, the higher the required total height H, and vice versa.

[0071] In a preferred embodiment, the total height H can be taken from [3, 20] mm.

[0072] In addition, considering functions such as preventing foreign objects from entering and aesthetics, the outlet 41 can be set relatively small, such as the cross-sectional area of ​​the outlet 41 not exceeding 10mm². 2 Preferably less than 5mm 2 .

[0073] Continue to refer to Figure 5 In some embodiments, the exhaust passage 4 may include: a first section 401, one end of which is connected to the outside; and a second section 402, which is connected to the other end of the first section 401 and directly or indirectly connected to the window 11, wherein there is a non-zero angle between the extending direction of the second section 402 and the extending direction of the first section 401. Thus, the angle between the first section 401 and the second section 402 can create a labyrinth structure in the exhaust passage 4, further enhancing the sealing effect.

[0074] In some embodiments, the cross-sectional area of ​​the first segment 401 and the cross-sectional area of ​​the second segment 402 may be the same along a plane perpendicular to the respective extending directions of the first segment 401 and the second segment 402. Alternatively, the cross-sectional area of ​​the first segment 401 may be smaller than the cross-sectional area of ​​the second segment 402.

[0075] In some embodiments, the cross-sectional areas of the first segment 401 and the second segment 402 are equal along their respective extending directions.

[0076] In one variation, the cross-sectional area of ​​the second segment 402 gradually decreases from the end near the first segment 401 to the end forming the outlet 41.

[0077] In some embodiments, there is a non-zero angle between the extension direction of the second segment 402 and the extension direction of the first segment 401, such that at least the first segment 401 and the second segment 402 of the exhaust passage 4 form an L-shaped, V-shaped or other zigzag channel structure.

[0078] In some embodiments, the outlet 41 is disposed adjacent to at least one of the left and right sides of the cover plate 3 in the horizontal direction (e.g., the x-direction and its opposite direction), the first section 401 extends in the horizontal direction, and the second section 402 extends in the opposite direction of gravity. Thus, an exhaust channel 4 with a sealing function can be formed simply and effectively.

[0079] In some embodiments, the length of the second segment 402 extending in the opposite direction of gravity is within a preset range, which is related to the area of ​​the cross-section of the segment extending in the opposite direction of gravity perpendicular to the direction of gravity. The length of the second segment 402 extending in the opposite direction of gravity is the total height H of the exhaust channel, or the height difference between the highest point 42 of the exhaust channel 4 and the outlet 41. Therefore, the relationship between the length of the second segment 402 extending in the opposite direction of gravity and the area of ​​the cross-section of the segment extending in the opposite direction of gravity perpendicular to the direction of gravity can be referred to the relevant description of the Lorentz formula above. Thus, a suitable combination of length and cross-sectional area can effectively prevent external water from entering the housing 1 through the exhaust channel 4.

[0080] In some embodiments, the length of the second segment 402 extending upward along the direction of gravity is within a preset range, namely 3-20 mm. Thus, within the range of 3-20 mm, the exhaust channel 4 can meet the requirements for water vapor discharge while effectively preventing external water from entering. It also reduces the area occupied by the exhaust channel 4, which is beneficial for improving the space utilization of the household appliance 100 and achieving a miniaturized design.

[0081] In some embodiments, the exhaust channel 4 further includes a third section 403, connecting the second section 402 and the window 11. Thus, the third section 402, as a connecting transition between the window 11 and the second section 402, better guides water vapor into the exhaust channel 4, reducing flow resistance and improving exhaust efficiency. The third section 403 further improves the structure of the exhaust channel 4, helping to better prevent external water from entering the interior of the exhaust channel 4.

[0082] In some embodiments, the household appliance 100 may further include a sealing structure 5 disposed around the window 11, the sealing structure being in contact with both the cover plate 3 and the housing 1, and the sealing structure 5 forming at least a portion of the boundary of the exhaust channel 4. Thus, while ensuring the exhaust and waterproof functions of the exhaust channel 4, the sealing characteristics of the sealing structure 4 can effectively prevent external moisture and impurities from entering the interior of the housing 1.

[0083] In some embodiments, the sealing structure 5 may be adhesive to simultaneously bond the housing 1 and the cover plate 3. For example, the sealing structure 5 may be formed by dispensing adhesive, or it may be formed by a material such as double-sided adhesive tape.

[0084] In some embodiments, the household appliance 100 may further include a rib 6 extending from the housing 1 toward the cover plate 3, the cover plate 3 being supported by the rib 6, and the rib 6 forming at least a portion of the boundary of the exhaust channel 4. Thus, the rib 6 serves to support the cover plate 3 and also acts as the boundary of the exhaust channel 4, simplifying the structure and reducing manufacturing costs.

[0085] In the application scenario of forming a sealing structure 5 by dispensing adhesive, the rib 6 can also be used to enclose the dispensing area so that the sealing structure 5 formed after the adhesive solidifies is only arranged within a predetermined range, avoiding the dispensing adhesive from overflowing into a non-predetermined range (e.g., entering the exhaust channel 4) when the cover plate 3 and the housing 1 are pressed together.

[0086] In some embodiments, continue to refer to Figure 4 The rib 6 includes a surrounding section 61 arranged around the window, the surrounding section having a first end 611 and a second end 612 forming the notch. The rib may further include: a first bent section 601 extending from the first end 611 toward the window 11; a second bent section 602 connected to the end of the first bent section 601 near the window 11, the extension direction of the second bent section 602 having a non-zero angle with the extension direction of the first bent section 601, the angle being, for example, 90°; a third bent section 603 extending from the second end 612 toward the window 11; and a fourth bent section 604 connected to the end of the third bent section 603 near the window 11, the extension direction of the fourth bent section 604 having a non-zero angle with the extension direction of the third bent section 603, the angle being, for example, 90°.

[0087] Furthermore, the first bending segment 601, the second bending segment 602, the third bending segment 603, the fourth bending segment 604, the surface of the housing 1 facing the y direction, and the cover plate 3 together form the exhaust channel 4.

[0088] Furthermore, the extension direction of the first bending segment 60 is parallel to the extension direction of the third bending segment 603, and the extension direction of the second bending segment 602 is parallel to the extension direction of the fourth bending segment 604.

[0089] In some embodiments, the housing 1 has an edge 12 surrounding the window 11 for mounting the cover plate 3, and the exhaust channel 4 is formed on the edge 12. Thus, the edge 12 provides a platform for the arrangement of the exhaust channel 4, making the structure and layout of the housing 1 more rational. Furthermore, the edge 12 can also be used for bonding to the housing 3 via the sealing structure 5.

[0090] In some embodiments, a groove 121 is formed on the edge 12, recessed in a direction away from the cover plate 3, the groove 121 being used to define at least a portion of the boundary of the exhaust channel 4. Thus, by creating a groove, the cross-sectional area of ​​the exhaust channel 4 can be further increased, ensuring smooth discharge of water vapor and reducing the height difference between the highest point 42 and the outlet 41 of the required exhaust channel 4, avoiding structural difficulties in meeting dimensional requirements.

[0091] Although specific embodiments have been described above, these embodiments are not intended to limit the scope of this disclosure, even when only a single embodiment is described with respect to a particular feature. The examples of features provided in this disclosure are intended to be illustrative and not limiting, unless otherwise stated.
