Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a range hood switch, a range hood panel and a range hood. Background Art

[0002] In the field of electrical switches, the upper and lower covers of switches are important parts to ensure the normal operation of electrical switches. However, the traditional design of switch lower covers often has problems such as insufficient sealing performance, poor structural stability, and difficulty in assembly and maintenance. Especially in environments with a lot of oil smoke, such as the range hood switch used in the kitchen, its sealing performance is particularly important to prevent the oil smoke from corroding the inside of the switch and affecting its service life and performance.

[0003] In addition, existing switch box designs often ignore the connection stability and assembly efficiency between the switch upper cover and the lower cover. Traditional connection methods may require the use of screws or other fasteners, which not only increases the complexity of assembly, but may also affect the overall stability of the switch box due to loosening or falling off.

[0004] In the field of range hoods, oil smoke erosion on switches is a common problem. Grease and impurities in the oil smoke easily adhere to the surface of the switch, which in turn affects the normal operation of the switch and even causes safety hazards. Therefore, it is very important to design a range hood switch that can effectively prevent oil smoke erosion.

[0005] At the same time, with the development of science and technology, users have higher and higher requirements for the aesthetics of electrical appliances. Traditional switch box designs often ignore this point, and the appearance is monotonous and lacks aesthetics. Utility Model Content

[0044] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0045] The terms "a", "an", "the", and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "comprising" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.

[0046] like Figures 1 to 4 As shown, a range hood switch of the embodiment of the utility model comprises: a switch upper cover 1, a switch lower cover 2, a switch display board 3 and a sealing ring 4; the switch lower cover 2 is clamped with the switch upper cover 1, and a mounting cavity is formed between the switch upper cover 1 and the switch lower cover 2; the switch display board (3) is installed in the mounting cavity; the switch lower cover 2 comprises a box body 21 with an opening at one end and a sealing groove surrounding the opening; two annular partition walls 22 are extended from the edge of the opening of the switch lower cover 2 in a direction away from the bottom of the box body 21, and a sealing groove is formed between the two annular partition walls 22; a sealing ring 4 is arranged in the sealing groove; the switch lower cover 2 is clamped with the switch upper cover 1, and a mounting cavity is formed between the switch upper cover 1 and the box body 21; the switch display board 3 is installed in the mounting cavity. When the range hood switch is installed on the range hood, the installation part of the range hood (i.e., the oil-proof edge of the lining plate 5) is installed in the sealing groove and abuts against the sealing ring.

[0047] When in use, the sealing ring 4 is installed in the sealing groove to prevent oil from entering the box body 21, thereby extending the service life of the switch assembly. During assembly, the lining plate 5 is pressed on the outer partition wall 22, and the oil-proof edge of the lining plate 5 is pressed on the sealing ring 4. The assembled box body 21 has a neater and more beautiful appearance. This not only improves the overall texture of the product, but also enhances the user experience.

[0048] Specifically, when the switch lower cover 2 is in use, its opening faces forward. Therefore, the box body 21 is in the shape of a rectangular parallelepiped, having four sides, upper, lower, left and right, and a rear, and the front is an open structure. Among them, the rear is a rectangle, and the upper, lower, left and right four sides are designed as planes perpendicular to the rear. This design makes the box more three-dimensional and dynamic visually, and also enhances the structural strength of the box, so that it can better resist deformation and damage when subjected to external forces.

[0049] Arc transitions are designed at the four corners of the box body 21 to make the appearance of the box body 21 more rounded, which not only improves the aesthetics of the box body 21, but also reduces possible collisions and damages during transportation and storage.

[0050] The two annular partition walls 22 are respectively an inner partition wall 221 and an outer partition wall 222 .

[0051] The inner isolation wall 221 extends outward from the edge of the opening of the box body 21 along the side of the box body 21. The inner isolation wall 221 and the side of the box body 21 are on the same plane and form a whole.

[0052] The outer partition wall 222 is composed of a connecting wall 2221 and an extension wall 2222. The connecting wall 2221 is formed by extending from the bottom of the inner partition wall 221, i.e., the edge of the opening of the box body 21, to the outside away from the box body 21. The plane where the connecting wall 2221 is located is parallel to the back of the box body 21. One end of the connecting wall 2221 away from the inner partition wall 221 extends in a direction away from the back of the box body 21 to form an extension wall 2222. The extension wall 2222 is parallel to the inner partition wall 221. The sealing groove is formed by the connecting wall 2221 as the bottom and the inner partition wall 221 and the extension wall 2222 as the wall surfaces on both sides.

[0053] Here, the thicknesses of the connecting wall 2221, the extending wall 2222, the inner isolation wall 221 and the box body 21 are all the same. This structure brings the following benefits:

[0054] Simplified production process: When the thickness of the connecting wall 2221, the extension wall 2222, the inner isolation wall 221 and the box body 21 are the same, it is not necessary to frequently adjust the production equipment or process parameters during the manufacturing process, which greatly simplifies the production process, improves production efficiency and reduces production costs.

[0055] Enhanced structural consistency: The design of uniform thickness makes the various parts of the box body 21 more consistent in structure and strength. This helps to ensure that when the box body 21 is subjected to external forces or pressures, each part can evenly disperse and resist these forces, thereby improving the overall stability and durability of the box body 21.

[0056] Improved sealing performance: Since the connecting wall 2221, the extension wall 2222, the inner isolation wall 221 and the box body 21 have the same thickness, the joints between them are tighter, reducing potential gaps or holes. This helps to enhance the sealing performance of the box body 21, prevent external impurities or contaminants from entering the box body 21, and protect the quality and safety of the items in the box body 21.

[0057] Enhanced aesthetics: The design of uniform thickness makes the appearance of the box body 21 more neat and uniform, and enhances the overall aesthetics of the box body 21. This design conforms to modern aesthetic trends and improves the market competitiveness of the product.

[0058] In a preferred embodiment, it also includes a wire outlet hole 23; the wire outlet hole 23 is arranged on the switch upper cover 1 or the switch lower cover 2 or between the switch upper cover 1 and the switch lower cover 2, and is used to insert the switch wire. One end of the switch wire is connected to the switch display board 3, and the other end is connected to the electric control component of the range hood.

[0059] The following takes the example of the wire outlet hole 23 being set on the switch lower cover 2 as an example for detailed description. Specifically, a slot is set on the isolation wall 22; after the switch upper cover 1 and the switch lower cover 2 are buckled together, the wire outlet hole 23 is formed at the slot. The wire outlet hole 23 is set below the box body 21. The below here refers to the below of the box body 21 after the range hood is installed in place.

[0060] When the wire outlet hole 23 is arranged on the switch upper cover 1, it is basically the same as when the wire outlet hole 23 is arranged on the switch lower cover 2, and will not be described in detail here.

[0061] The wire outlet hole 23 is arranged between the switch upper cover 1 and the switch lower cover 2, which is the sum of the above two solutions and will not be described in detail here.

[0062] The design of the outlet hole 23 allows the power line or other connecting lines to be directly led out from the bottom of the switch lower cover 2, which is convenient for wiring and installation, while preventing the cables from being exposed to the outside and affecting the overall appearance and safety of the switch. In addition, the outlet hole 23 is designed near the lower side of the box body 21 to prevent oil drops from entering the switch along the switch line, causing damage to the switch.

[0063] The size of the outlet hole 23 is adapted to the switch line. Specifically, the outlet hole 23 is designed with a small opening, and the size of the outlet hole 23 is compressed to only the size of the switch line, and then sealed with sealant. This brings the following benefits:

[0064] 1. Improve safety: The small opening design can reduce the chance of external factors such as oil smoke, dust, moisture and other impurities entering the box body 21. This design can fit the switch line tightly and prevent foreign substances from entering through the outlet hole 23, thereby reducing the potential risk of electrical failure or short circuit.

[0065] 2. Enhanced sealing: Since the size of the outlet hole 23 is adapted to the switch wire, when the switch wire passes through the outlet hole 23, the gap between the hole and the wire is very small, which helps to improve the sealing performance of the box body 21. This sealing can prevent harmful gases such as smoke, liquids or dust from entering the box body 21 through the outlet hole 23, protecting the electronic components and equipment in the box body 21 from damage.

[0066] 3. Convenient installation and maintenance: The size of the outlet hole 23 is adapted to the switch line, which means that no additional adjustment or adaptation work is required when installing the switch line. This simplifies the installation process and improves installation efficiency. At the same time, when the switch line needs to be maintained or replaced, the adapted outlet hole 23 can also provide convenience, making the operation simpler and faster.

[0067] 4. Improve structural strength: Through the small opening design, the size of the outlet hole 23 is only suitable for the switch line; that is, the material removed by the opening is small, which has little effect on the structural strength of the box body 21, thereby improving the strength of the box body 21.

[0068] 5. Improve overall aesthetics: The design of the adapted outlet hole 23 makes the appearance of the box body 21 more neat and beautiful. There are no holes that are too large or too small, and the appearance of the box body 21 is more unified and coordinated, which improves the overall aesthetics.

[0069] In another preferred embodiment, the depth of the groove is lower than the bottom of the sealing groove. This design can maintain the sealing performance of the sealing ring 4 and allow the switch line to pass smoothly.

[0070] The switch cover 1 is provided with a snap-fit ​​protrusion 6, and the box body 21 is provided with a snap-fit ​​groove 7; the switch cover 1 is snap-fitted into the snap-fit ​​groove 7 through the snap-fit ​​protrusion 6 and connected to the box body 21; an installation cavity is formed between the switch cover 1 and the box body 21.

[0071] The shape of the switch upper cover 1 is substantially the same as the structure of the box body 21 of the switch lower cover 2, and will not be described in detail herein.

[0072] There are two clamping grooves 7 arranged on the box body 21, respectively on the inner wall of the left and right sides of the box body 21. At the same time, there are also two clamping protrusions 6, arranged on the outer wall of the left and right sides of the switch cover 1.

[0073] The above scheme design brings the following benefits:

[0074] Fast and stable assembly: Through the adaptive snap-fit ​​design of the snap-fit ​​protrusion 6 and the snap-fit ​​groove 7, the connection between the switch cover 1 and the box body 21 is fast and stable. This design avoids the use of complex fasteners or screws, thereby simplifying the assembly process and improving assembly efficiency.

[0075] Enhanced structural stability: The design of the snap-fit ​​protrusion 6 and the snap-fit ​​groove 7 forms a firm connection between the switch cover 1 and the box body 21. This connection can effectively resist external pressure and vibration, enhance the overall structural stability of the switch box, and prevent problems caused by loosening or falling off.

[0076] Easy maintenance and replacement: Due to the snap-on design, when the switch cover 1 needs to be maintained or replaced, the switch cover 1 can be easily removed from the box body 21 by simply releasing the snap-on connection. This greatly simplifies the maintenance and replacement process and reduces maintenance costs.

[0077] Improved aesthetics: The design of the snap-fit ​​protrusion 6 and the snap-fit ​​groove 7 makes the connection between the switch cover 1 and the box body 21 more concealed and aesthetically pleasing. This design avoids the use of visible fasteners or screws, making the appearance of the switch box more neat and uniform.

[0078] Strong adaptability: The design of the snap-fit ​​protrusion 6 and the snap-fit ​​groove 7 has a certain adaptability, and can adapt to switch covers 1 and box bodies 21 of different sizes and shapes. This provides greater flexibility for the design of the switch box and meets the needs of different application scenarios.
