Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to an electric cooker. Background Technology

[0002] Electric cookware, such as electric frying pans, typically has a power cord that is separate from the casing for easy storage, with the power cord socket usually located on the side wall of the casing. Because this type of socket is exposed, water can easily enter through the gap between the socket and the casing, or dust can accumulate inside the socket, making it difficult to clean and potentially causing short circuits or other hazards.

[0003] Some related technologies use sealing rings and dust caps for waterproofing and dustproofing. However, the installation structure of sealing rings and dust caps is complex, resulting in low assembly efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide an electric cooker to address the above problems, thereby simplifying its structure and improving assembly efficiency.

[0005] This utility model provides an electric cooker, including: a pot body with an assembly hole; a socket assembly disposed in the assembly hole, including a socket; and a sealing cover, the sealing cover including a sealing part and a cover part integrally connected to the sealing part, the cover part being movably integrally connected to the sealing part, the sealing part being sandwiched between the socket and the hole wall of the assembly hole, and the cover part being able to open and close to seal the assembly hole.

[0006] In the aforementioned electric cooker, the sealing part prevents external liquids and dust from entering the pot body through the gap between the socket and the mounting hole, thus preventing short circuits and other hazards. When the lid is closed, it also prevents external liquids and dust from entering the pot body and socket assembly through the mounting hole, ensuring the normal operation of the electric cooker and facilitating cleaning of the pot body. Thus, the sealing lid provides waterproofing and dustproofing. Furthermore, since the lid and sealing part are movably and integrally connected, the number of parts is reduced, the assembly process is simplified, and the lid is prevented from being lost, improving ease of use.

[0007] In one embodiment, the sealing cap further includes a connecting portion, the inner side of the sealing cap being integrally connected to the sealing portion near the outer periphery via the connecting portion, and capable of movably opening and closing the assembly hole relative to the sealing portion.

[0008] This design reduces localized deformation of the sealing part when the cover is opened, ensuring a good seal.

[0009] In one embodiment, one of the sealing portion or the wall of the mounting hole is provided with an annular groove, and the other is provided with an annular protrusion that mates with the groove.

[0010] This design ensures the stability and reliability of the connection between the two components, increases the contact area, extends the flow path of external liquids and dust into the pot body, and improves the sealing effect.

[0011] In one embodiment, the pot body includes a housing, a handle and / or a handle, the handle and / or handle being disposed in the housing, and the mounting hole being disposed in the handle or handle.

[0012] With this design, the mounting hole is located on the handle or grip, which allows the socket assembly to be separated from the heating element inside the pot. This avoids damage to the socket assembly caused by high-temperature environments, improves safety, and extends service life.

[0013] In one embodiment, the handle or grip has a mounting groove on the side away from the housing, and the cover includes a cover body. When the cover covers the mounting hole, the cover body is interference-fitted with the mounting groove.

[0014] This design ensures the stability and reliability of the sealing part when it is closed, preventing accidental opening; when the cover is compressed, it can fit tightly against the inner wall of the assembly groove, increasing the contact area and improving the sealing effect.

[0015] In one embodiment, the cover portion further includes a rib that is interference-fitted with the opening of the mounting hole.

[0016] This design improves the stability and reliability of the cover in the closed state, prevents the cover from opening accidentally, and also prevents the cover from shifting relative to the mounting hole. When the rib is compressed, it can fit tightly against the wall of the mounting hole, increasing the contact area and improving the sealing effect, thus achieving a double seal between the cover and the rib.

[0017] In one embodiment, the socket assembly further includes a cover fixed to the cooker body, the cover being fitted over the socket.

[0018] This design prevents liquids or dust from entering the socket, thus protecting it. Furthermore, the cover acts as a fire barrier, preventing external open flames from contacting the socket and causing safety hazards. It also prevents sparks from short circuits or leaks in the socket and other internal electrical components from igniting the cooker, improving safety during use.

[0019] In one embodiment, the outer side of the cover is provided with a fixing hole, the socket has a flange located outside the cover, the two sides of the flange abut against the end of the cover and the sealing part respectively, and the fixing hole is fixed to the pot body by fasteners to press the socket and the sealing part into the pot body.

[0020] This design allows the cover, socket, and sealing cap to be secured to the pot body simultaneously using fasteners, simplifying the assembly process. Furthermore, the tightening of the sealing parts improves the sealing effect.

[0021] In one embodiment, the cover is made of flame-retardant material.

[0022] With this design, the flame-retardant material can suppress electrical spark breakdown, prevent high-voltage leakage, and slow the spread of fire, thereby improving the fire resistance of the enclosure and enhancing its safety.

[0023] In one embodiment, the socket has a power terminal located inside the housing.

[0024] This design prevents fires caused by electrical sparks during plugging and unplugging of the terminals, thus improving safety. Attached Figure Description

[0038] Electric cookware, such as electric frying pans, typically has a power cord that is separate from the casing for easy storage, with the power cord socket usually located on the side wall of the casing. Because this socket is exposed, water can easily enter through the gap between the socket and the casing, or dust can accumulate inside the socket, making it difficult to clean and increasing the risk of short circuits. Some related technologies use sealing rings and dust caps for waterproofing and dustproofing, but the installation structure of these sealing rings and dust caps is complex, resulting in low assembly efficiency.

[0039] To solve the above problems, such as Figures 1 to 6 As shown, this utility model provides an electric cooker to simplify the structure and improve assembly efficiency.

[0040] like Figures 1 to 3 As shown, specifically, the electric cooker includes a pot body 10, a socket assembly 20, and a sealing cover 30, wherein: the pot body 10 is provided with an assembly hole 11; the socket assembly 20 is disposed in the assembly hole 11 and includes a socket 21; the sealing cover 30 includes a sealing part 31 and a capping part 32 integrally connected to the sealing part 31, the capping part 32 and the sealing part 31 are integrally connected movably, the sealing part 31 is sandwiched between the socket 21 and the hole wall of the assembly hole 11, and the capping part 32 can be opened and closed to seal the assembly hole 11.

[0041] In the electric cooker provided in this embodiment of the utility model, when it is necessary to connect the power cord, the cover 32 is first opened, and then the power cord is electrically connected to the socket 21 at the assembly hole 11. Since the sealing part 31 is sandwiched between the socket 21 and the hole wall of the assembly hole 11, it can prevent external liquids, dust, etc. from entering the interior of the cooker body 10 through the gap between the socket 21 and the hole wall of the assembly hole 11, thus preventing short circuits and other dangers, ensuring the normal operation of the electric cooker. After use, the power cord is first disconnected from the socket 21, and then the cover 32 is closed, so that the assembly hole 11 is sealed. At this time, it can prevent external liquids, dust, etc. from entering the cooker body 10 and the socket assembly 20 through the assembly hole 11, thus preventing short circuits and other dangers, ensuring the normal operation of the electric cooker, and also facilitating the cleaning of the cooker body 10. In this way, waterproofing and dustproofing can be achieved through the sealing cover 30. Since the cover 32 and the sealing part 31 are movably and integrally connected, the structure can be simplified, the assembly efficiency can be improved, and the cover 32 can be prevented from being lost, improving the convenience of use.

[0042] The sealing cap 30 can be made of waterproof, high-temperature resistant and elastic materials such as silicone, rubber, and thermoplastic elastomer.

[0043] like Figure 1 and Figure 3 As shown, the pot body 10 includes a shell 12, a handle 13, and a handle 14, with the handle 13 and handle 14 disposed on the shell 12. During cooking, the user can hold the handle 13, and when it is necessary to lift the entire electric pot, the user can hold the handle 13 and handle 14 with both hands respectively, ensuring safety. Of course, in other embodiments, the pot body 10 may only have one of the handles or handles, which is disposed on the shell 12, making it convenient for the user to hold either the handle or handle during cooking.

[0044] In one embodiment, the mounting hole 11 is provided in the handle 14. Specifically, refer to... Figure 1 and Figure 3 As shown, since users typically point handle 13 towards their body and handle 14 towards the external plug during cooking, the mounting hole 11 located on handle 14 shortens the distance between socket 21 and the external plug, facilitating power cord connection and preventing the power cord from interfering with user operation. Furthermore, separating the socket assembly 20 from the heating element inside the pot body 10 prevents damage to the socket assembly 20 due to high temperatures, improving safety and extending its lifespan. Simultaneously, the socket assembly 20 does not occupy internal space within the pot body 10, avoiding an increase in the overall size of the electric cooker. Specifically, the mounting hole 11 is located at the end of handle 14 furthest from the housing 12 for convenient operation. Alternatively, the mounting hole 11 can also be located on the side wall where handle 14 connects to housing 12.

[0045] Of course, in other embodiments, the mounting hole 11 may also be provided on the side wall of the housing 12 or on the handle 13. Furthermore, the relative positions of the handle 13 and the handle 14 can also be adjusted according to actual needs. The pot body 10 may only include the housing 12 and the handle 13, or only include the housing 12. This embodiment of the present invention does not impose specific limitations here.

[0046] In one embodiment, the sealing cap 30 further includes a connecting portion 33, which is integrally connected to the sealing portion 31 near the outer periphery of the sealing portion 32, and can movably open and close the mounting hole 11 relative to the sealing portion 31. The connecting portion 33 ensures that the sealing portion 32 remains integrally connected to the sealing portion 31 during opening and closing, and reduces local deformation of the sealing portion 31 when the sealing portion 32 is opened, ensuring a sealing effect. Figures 4 to 5As shown, the inner part of the cover portion 32 is integrally connected to the sealing portion 31 via the connecting portion 33 near the top outer periphery. Of course, in other embodiments, the inner part of the cover portion 32 may also be integrally connected to the sealing portion 31 via the connecting portion 33 near the bottom outer periphery, or the inner part of the cover portion 32 may be integrally connected to the sealing portion 31 via the connecting portion 33 near the side outer periphery.

[0047] like Figure 2 and Figure 5 As shown, in one embodiment, one of the sealing part 31 or the wall of the mounting hole 11 is provided with an annular groove 311, and the other is provided with an annular protrusion 111 that mates with the groove 311. The sealing part 31 and the wall of the mounting hole 11 are fixed together by the groove 311 and the protrusion 111, which ensures the stability and reliability of the connection between the two, increases the contact area, extends the flow path of external liquids, dust, etc. into the pot body 10, and improves the sealing effect. In addition, the groove 311 and the protrusion 111 can also play a role in installation positioning, which facilitates installation.

[0048] In the illustrated embodiment, the sealing portion 31 is provided with a groove 311, and the wall of the mounting hole 11 is provided with a protrusion 111. The protrusion 111 extends from the wall of the mounting hole 11 toward the housing 12. The sealing portion 31 includes a first sealing section 312, a second sealing section 313, and a third sealing section 314 surrounding the groove 311. The opening of the groove 311 is away from the side of the housing 12. Specifically, the first sealing section 312 fits against the inner peripheral wall of the protrusion 111, one end of the connecting portion 33 is connected to the top of the first sealing section 312, the second sealing section 313 is connected to the end of the first sealing section 312 away from the connecting portion 33 and fits against the end of the protrusion 111, and the third sealing section 314 is connected to the end of the second sealing section 313 away from the first sealing section 312 and fits against the outer peripheral wall of the protrusion 111. The socket 21 presses the second sealing section 313 against the end of the protrusion 111 to prevent the sealing portion 31 from accidentally coming out of the mounting hole 11.

[0049] Of course, in other embodiments, the sealing part 31 and the hole wall of the assembly hole 11 can also be fixed by other means such as snap-fit, screw connection, or adhesive. As long as the stability and reliability of the connection between the sealing cover 30 and the pot body 10 can be guaranteed, this utility model embodiment does not make specific limitations here.

[0050] like Figure 2 and Figure 5As shown, in one embodiment, when the mounting hole 11 is provided on the handle 14, the side of the handle 14 away from the housing 12 is provided with a mounting groove 141. The cover part 32 includes a cover body 321. When the cover part 32 covers the mounting hole 11, the cover body 321 and the mounting groove 141 are interference-fitted. In this way, the stability and reliability of the cover part 32 in the closed state can be ensured, and the cover part 32 can be prevented from being opened accidentally. After being squeezed, the cover body 321 can be pressed tightly against the inner wall of the mounting groove 141, increasing the contact area and improving the sealing effect. Moreover, when closing the cover part 32, it is only necessary to press the cover body 321 into the mounting groove 141, which is convenient for operation. Of course, in other embodiments, the stability and reliability of the cover part 32 in the closed state can also be achieved by other structures such as buckles, elastic elements, and fasteners. This utility model embodiment does not make specific limitations here.

[0051] In other embodiments, when the mounting hole 11 is provided on the handle 13, the mounting groove 141 is provided on the side of the handle 13 away from the housing 12. The cover portion 32 includes a cover body 321. When the cover portion 32 covers the mounting hole 11, the cover body 321 and the mounting groove 141 are interference-fitted. In this way, the stability and reliability of the cover portion 32 in the closed state can be ensured, and the cover portion 32 can be prevented from being opened accidentally. When the cover body 321 is squeezed, it can fit tightly against the inner wall of the mounting groove 141, increasing the contact area and improving the sealing effect.

[0052] like Figure 5 As shown, the cap 32 also includes a rib 322, which is interference-fitted into the opening of the mounting hole 11. The rib 322 protrudes from the side of the cap 321 facing the handle 14. This further improves the stability and reliability of the cap 32 in the closed state, prevents the cap 32 from opening accidentally, and prevents the cap 32 from shifting relative to the mounting hole 11. When compressed, the rib 322 can fit tightly against the wall of the mounting hole 11, further increasing the contact area and improving the sealing effect, achieving a double seal from the cap 321 and the rib 322.

[0053] like Figure 2 and Figure 5 As shown, the cap 32 further includes an operating part 323 located on the side of the cap 321 opposite to the handle 14. The operating part 323 can be a protrusion or a groove, and is preferably located at the end of the cap 321 away from the connecting part 33. The user can open or close the cap 32 via the operating part 323.

[0054] like Figure 2 and Figure 5As shown, the socket assembly 20 also includes a cover 22 fixed to the pot body 10, which is fitted over the socket 21. The cover 22 can further prevent liquids or dust from entering the socket 21, thereby protecting the socket 21; and the cover 22 can also act as a fire barrier, preventing external open flames from contacting the socket 21 and causing safety hazards. It also prevents electrical sparks generated by short circuits or leakage in the internal electrical components of the socket 21 from igniting the handle 14, thus improving safety. This allows the electric cooker to achieve triple protection of waterproofing, dustproofing, and fireproofing.

[0055] In one embodiment, the enclosure 22 is made of flame-retardant materials, such as flame-retardant plastics, flame-retardant alloys, or flame-retardant silicone rubber. Flame-retardant materials can suppress electrical spark breakdown, prevent high-voltage leakage, and delay the spread of fire, thereby further improving the fire-resistant effect of the enclosure 22 and enhancing its safety. Of course, in other embodiments, the enclosure 22 can also be made of other materials to achieve physical fire isolation; or, a flame-retardant material layer can be added to the surface of the enclosure 22, which is made of stainless steel, metal, or other materials, to improve its fire-resistant effect.

[0056] like Figure 2 and Figure 6 As shown, in one embodiment, the outer side of the cover 22 is provided with a fixing hole 221, and the socket 21 has a flange 211 located outside the cover 22. The two sides of the flange 211 abut against the end of the cover 22 and the sealing part 31, respectively. The fixing hole 221 is fixed to the pot body 10 by fasteners 40 such as screws, bolts, and rivets, so as to press the socket 21 and the sealing part 31 into the pot body 10. In this way, the cover 22, the socket 21 and the sealing cover 30 can be fixed to the pot body 10 at the same time by fasteners 40, simplifying the assembly process, and the sealing part 31 being pressed can also improve the sealing effect.

[0057] In the illustrated embodiment, there are two fixing holes 221, which are respectively located on both sides of the cover 22 to ensure the stability and reliability of the connection between the cover 22, the socket 21, the sealing part 31, and the pot body 10. When the fixing holes 221 are fixed to the pot body 10 by fasteners 40, the end of the cover 22 presses the flange 211 and the second sealing section 313 against the end of the protrusion 111. Alternatively, while ensuring the stability and reliability of the connection between the cover 22 and the pot body 10, the number of fixing holes 221 can also be one, three, four, or more. It is preferable that the multiple fixing holes 221 are arranged at intervals along the circumference of the cover 22.

[0058] Of course, in other embodiments, the cover 22 and the socket 21 can also be fixedly connected to the pot body 10 by fasteners 40, snaps, adhesives, etc.; or, the socket 21 can be fixedly connected to the cover 22 by fasteners 40, snaps, adhesives, etc., and then the cover 22 and the socket 21 can be fixedly connected to the pot body 10 by fasteners 40, snaps, adhesives, etc., as long as the stability and reliability of the connection between the socket assembly 20 and the pot body 10 can be guaranteed, this utility model embodiment does not make specific limitations here.

[0059] like Figure 5 As shown, the socket 21 has a power terminal 212 located inside the housing 22. The power terminal 212 is electrically connected to the electrical components inside the cooker body 10 and is also used for electrical connection to the power cord. Since the power cord is prone to generating electric sparks during insertion and removal, placing the power terminal 212 inside the housing 22 can prevent the power terminal 212 from igniting due to electric sparks during insertion and removal, thus improving safety. The power terminal 212 can be a coupling terminal, ensuring a reliable connection between the power cord and the power terminal 212 while facilitating operation; alternatively, the power terminal 212 can be a screw-type, spring-type, or other connection type terminal. This embodiment of the invention does not impose specific limitations here.

[0060] like Figure 1 As shown, the electric cooking appliance can be an electric frying pan, an electric cooking pot, an electric steamer, an electric stew pot, an electric griddle, etc., and this embodiment of the utility model does not impose specific limitations.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0062] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
