[0032] An electric hot pot is a kitchen cooking appliance that can be used for cooking operations such as stir-frying, frying, and boiling to meet different cooking needs, making the electric hot pot one of the indispensable appliances in the kitchen. Existing electric hot pots mainly include a shell and a pot body, with a heating element and related electronic devices arranged between the shell and the pot body. Since various electronic devices are arranged between the shell and the pot body, special care needs to be taken when cleaning the electric hot pot to prevent water from entering between the shell and the pot body and contacting the electronic devices, which may cause short circuits and the like.
[0033] In order to solve the above problems, Figures 1 to 3 As shown, the present application provides an electric hot pot to prevent water from entering between the outer shell and the pot body, thereby protecting electronic components.
[0034] like Figure 1 to Figure 2 As shown, specifically, the electric hot pot includes an inner pot 10, an outer shell 20, a heating assembly 30 and a sealing assembly 40, wherein: the inner pot 10 has a first upper edge 11, the inner pot 10 is arranged in the outer shell 20, the outer shell 20 has a second upper edge 21, and the heating assembly 30 is located between the inner pot 10 and the outer shell 20; the sealing assembly 40 includes a sealing member 41 and a fixing member 42, the sealing member 41 is clamped between the first upper edge 11 and the second upper edge 21, the fixing member 42 includes a connecting edge 421 and extended edges 422 located at both ends of the connecting edge 421, and the connecting edge 421 and the two extended edges 422 surround a clamping cavity 423, the first upper edge 11, the sealing member 41 and the second upper edge 21 are at least partially located in the clamping cavity 423, and the two extended edges 422 are respectively pressed against the first upper edge 11 and the second upper edge 21.
[0035] In the electric hot pot provided by the embodiment of the utility model, the sealing member 41 is sandwiched between the first upper edge 11 and the second upper edge 21 to play a sealing role, so as to prevent water from entering between the inner pot 10 and the outer shell 20 through the gap between the first upper edge 11 and the second upper edge 21, causing the heating component 30 and other electronic devices to contact with water and cause a short circuit, etc.; the fixing member 42 is used to fix the first upper edge 11, the sealing member 41 and the second upper edge 21 to prevent the sealing member 41 from falling off, and the first upper edge 11, the sealing member 41 and the second upper edge 21 are partially located In the clamping cavity 423, the fixing part 42 wraps the edges of the first upper edge 11, the sealing part 41 and the second upper edge 21, so that the edges of the first upper edge 11, the sealing part 41 and the second upper edge 21 are not exposed, and water does not contact the edges, thereby improving the waterproof effect, protecting the heating component 30 and other electronic devices between the inner pot 10 and the outer shell 20, and facilitating the user to clean the electric hot pot, so that the grease inside and outside the electric hot pot can be cleaned by water. At the same time, the fixing part 42 can also play a decorative role, improving the aesthetics of the electric hot pot.
[0036] On the other hand, the two extended edges 422 are respectively pressed against the first upper edge 11 and the second upper edge 21, and relative pressure can be applied to the first upper edge 11 and the second upper edge 21, so that the two extended edges 422 can clamp and fix the first upper edge 11, the seal 41 and the second upper edge 21, and the first upper edge 11 and the second upper edge 21 can also clamp and fix the seal 41, thereby improving the sealing effect and the connection strength between the inner pot 10, the outer shell 20 and the sealing assembly 40, thereby ensuring the reliability of the electric hot pot.
[0037] The inner pot 10 is used to hold food, and the heating component 30 is used to heat the food in the inner pot 10. In addition, the electric hot pot can be an electric frying pan, an electric boiling pot, an electric hot pot, etc., in which the inner pot 10 and the outer shell 20 are connected, and the food in the inner pot 10 is heated by the heating component 30 between the inner pot 10 and the outer shell 20, and the embodiment of the utility model is not specifically limited here.
[0038] like Figure 1 to Figure 2 As shown, the shell 20 is made of metal material, and the thickness H3 of the shell 20 satisfies: 0.4mm≤H3≤2.0mm. The metal material can be selected from stainless steel, aluminum, alloy and other metals. Among them, the thickness H3 of the shell 20 can be any value within the range of 0.4mm≤H3≤2.0mm, such as 0.4mm, 0.41mm, 0.42mm...0.5mm, 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, 2.0mm, etc. Compared with the plastic shell, the shell 20 made of metal material can ensure the strength and high temperature resistance of the electric hot pot while making the thickness of the shell 20 thinner and lighter, thereby reducing the overall volume and weight of the electric hot pot, which is convenient for users to use and store.
[0039] like Figure 2 As shown, at least one of the extension edges 422 is provided with a curl 4221 at one end away from the connection edge 421. When both extension edges 422 are provided with curls 4221, the two curls 4221 bend and extend from the end of the extension edge 422 away from the connection edge 421 toward the first upper edge 11 and the second upper edge 21, and respectively press the first upper edge 11 and the second upper edge 21. The two curls 4221 are respectively used to apply relative pressure to the first upper edge 11 and the second upper edge 21 to clamp and fix the first upper edge 11, the sealing member 41 and the second upper edge 21, further improving the connection strength between the inner pot 10, the outer shell 20 and the sealing assembly 40; at the same time, the curl 4221 can also improve the strength of the extension edge 422 itself, improve the reliability of the fixing member 42, and prevent the fixing member 42 from falling off.
[0040] When only the extended edge 422 in contact with the first upper edge 11 is provided with the curl 4221, the curl 4221 presses against the first upper edge 11 and can apply pressure to the first upper edge 11 toward the second upper edge 21, thereby also being able to clamp and fix the first upper edge 11, the seal 41 and the second upper edge 21; similarly, when only the extended edge 422 in contact with the second upper edge 21 is provided with the curl 4221, the curl 4221 presses against the second upper edge 21 and can apply pressure to the second upper edge 21 toward the first upper edge 11, thereby also being able to clamp and fix the first upper edge 11, the seal 41 and the second upper edge 21.
[0041] Furthermore, the fixing member 42 and the curled circle 4221 of the fixing member 42 can also prevent the sharp corners and burrs on the edges of the first upper edge 11, the second upper edge 21 and the extended edge 422 from scratching the user's hands, thereby ensuring the safety of the user when using and cleaning the electric hot pot.
[0042] In another embodiment, the two extended edges 422 contact the first upper edge 11 and the second upper edge 21 respectively, but do not apply pressure to the first upper edge 11 and the second upper edge 21 , as long as the sealing member 41 does not fall off the first upper edge 11 and the second upper edge 21 .
[0043] like Figure 2 As shown, the connecting edge 421 and the extending edge 422 are integrally formed to ensure the reliability of the connection between the connecting edge 421 and the extending edge 422, simplify the processing steps, and facilitate the production and assembly of the fixing member 42. In addition, the integrally formed setting also makes the outer surface at the connection between the connecting edge 421 and the extending edge 422 a smooth surface, without sharp corners and burrs, and the user will not be scratched during use. Of course, the connecting edge 421 and the extending edge 422 can also be fixedly connected by other means such as welding, as long as the reliable connection between the two can be ensured, and the embodiment of the utility model is not specifically limited here.
[0044] Furthermore, the fixing member 42 is preferably made of aluminum or stainless steel. Aluminum is light in weight, so that the overall weight of the electric hot pot can be reduced, making it easier for users to use. Stainless steel has the characteristics of corrosion resistance, high temperature resistance and high strength, which can ensure that the fixing member 42 is not easily deformed during long-term use, thereby extending the service life. In addition, aluminum and stainless steel also have good plasticity and weldability, and are easy to be processed into various shapes, so that the connecting edge 421, the extended edge 422 and the curling 4221 on the extended edge 422 can be easily processed.
[0045] In addition, the outer surface of the fixing member 42 is polished to form a sanded surface or a mirrored surface. The outer surface of the fixing member 42 can be made into a sanded surface or a mirrored surface to further enhance the aesthetics of the electric hot pot.
[0046] like Figures 2 to 3 As shown, the sealing member 41 includes a first sealing portion 411 and a second sealing portion 412, the first sealing portion 411 is connected to the middle of the second sealing portion 412, the first sealing portion 411 is located between the bottom surface of the first upper edge 11 and the top surface of the second upper edge 21, and the second sealing portion 412 is located between the end surface of the first upper edge 11, the end surface of the second upper edge 21 and the connecting edge 421. The first sealing portion 411 is used to seal the gap between the first upper edge 11 and the second upper edge 21, and the second sealing portion 412 is used to seal the end surface of the first upper edge 11 and the end surface of the second upper edge 21, thereby achieving sealing of the first upper edge 11 and the second upper edge 21 in multiple directions, further improving the sealing effect, and preventing water from entering between the inner pot 10 and the outer shell 20 through the gap between the first upper edge 11, the sealing member 41 and the second upper edge 21.
[0047] At the same time, the second sealing portion 412 can also play a positioning role. The first sealing portion 411 is inserted between the first upper edge 11 and the second upper edge 21. When the second sealing portion 412 abuts against the end faces of the first upper edge 11 and the second upper edge 21, the seal 41 is installed in place, thereby facilitating the user to install the seal 41.
[0048] The first sealing portion 411 may be connected to the middle position of the second sealing portion 412 to form a T-shaped structure, in which case the length of the portion where the second sealing portion 412 fits with the end surface of the first upper edge 11 is equal to the length of the portion where the second sealing portion 412 fits with the end surface of the second upper edge 21. Alternatively, the first sealing portion 411 may also be connected to the middle of the second sealing portion 412 and the two sides, in which case the length of the portion where the second sealing portion 412 fits with the end surface of the first upper edge 11 is longer than the length of the portion where the second sealing portion 412 fits with the end surface of the second upper edge 21, or the length of the portion where the second sealing portion 412 fits with the end surface of the first upper edge 11 is shorter than the length of the portion where the second sealing portion 412 fits with the end surface of the second upper edge 21, as long as the second sealing portion 412 can fit with both the end surface of the first upper edge 11 and the end surface of the second upper edge 21.
[0049] like Figure 3 As shown, the first sealing portion 411 and the second sealing portion 412 are integrally formed to ensure the reliability of the connection between the first sealing portion 411 and the second sealing portion 412, simplify the processing steps, and facilitate the production and assembly of the sealing member 41. Of course, the first sealing portion 411 and the second sealing portion 412 can also be fixedly connected by welding, gluing, or other methods, as long as a reliable connection between the two can be ensured, and the embodiment of the utility model is not specifically limited here.
[0050] like Figure 3 As shown, the thickness H1 of the first sealing portion 411 and the thickness H2 of the second sealing portion 412 satisfy: H1 / H2≥1. That is, the thickness H1 of the first sealing portion 411 is equal to the thickness H2 of the second sealing portion 412, or the thickness H1 of the first sealing portion 411 is thicker than the thickness H2 of the second sealing portion 412. The thickness H1 of the first sealing portion 411 refers to the dimension of the first sealing portion 411 along the height direction of the electric hot pot, and the thickness H2 of the second sealing portion 412 refers to the dimension of the second sealing portion 412 along the radial direction of the electric hot pot. The thickness H1 of the first sealing part 411 is relatively thick and has a strong deformation ability. When the first upper edge 11 and the second upper edge 21 squeeze the first sealing part 411, the first sealing part 411 can be greatly deformed, so that the first sealing part 411 has a better sealing effect between the first upper edge 11 and the second upper edge 21; and increasing the thickness H1 of the first sealing part 411 can also increase the overall thickness of the upper edge of the electric hot pot without increasing the weight of the electric hot pot, thereby improving the user experience. The thickness H2 of the second sealing part 412 is relatively thin, so as to avoid increasing the circumference of the upper edge of the electric hot pot and facilitate storage.
[0051] Specifically, the thickness H1 of the first sealing portion 411 satisfies: 0.8mm≤H1≤6mm, wherein the thickness H1 of the first sealing portion 411 can be any value within the range of 3mm≤H1≤6mm, such as 0.8mm, 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, etc. The thickness H2 of the second sealing portion 412 satisfies: 0.6mm≤H2≤3mm, wherein the thickness H2 of the second sealing portion 412 can be any value within the range of 1mm≤H1≤3mm, such as 0.6mm, 0.8mm, 1mm, 2mm, 3mm, etc. When the thickness H1 of the first sealing portion 411 and the thickness H2 of the second sealing portion 412 meet the above dimensions, the sealing effect of the sealing member 41 on the first upper edge 11 and the second upper edge 21 and the size of the electric hot pot are more suitable, and the production and manufacturing costs are low.
[0052] Furthermore, the sealing member 41 can be configured as a silicone member or a rubber member, which ensures a sealing effect while having a low cost and is easy to produce and process.
[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0054] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
