Description

Technical Field

[0001] This application relates to the field of household appliance technology, specifically to an electric ceramic stove. Background Technology

[0002] With the continuous development of technology and the improvement of people's living standards, kitchen appliances have gradually become an indispensable part of modern family life. As a new type of kitchen heating equipment, the electric ceramic cooktop has been widely welcomed for its advantages such as high efficiency, energy saving, and environmental friendliness. An electric ceramic cooktop is a stove that utilizes the principle of infrared heating, generating heat through nickel-chromium wires in the cooktop plate to perform various cooking tasks.

[0003] In related technologies, the heating element of an electric ceramic cooker is typically housed within its bottom shell, with a control panel located at the top opening of the bottom shell. During operation, the heating element generates high temperatures that act on the control panel; however, this high temperature can cause thermal damage to the bottom shell. Therefore, the bottom shell is usually made of a heat-resistant material.

[0004] However, when the bottom shell is made of high-temperature resistant materials, the production cost of the bottom shell is high, and the bottom shell is prone to deformation and has a short lifespan. Utility Model Content

[0005] This application provides an electric ceramic stove that can solve the technical problems of high production cost of the bottom shell, easy deformation of the bottom shell, and short life of the bottom shell.

[0006] To solve the above-mentioned technical problems, this application provides an electric ceramic stove, comprising:

[0007] Bottom shell;

[0008] The panel and the bottom shell together form a receiving cavity;

[0009] The heating plate and the heat insulation support are both located within the receiving cavity; the heat insulation support is connected to the bottom shell; the heating plate is connected to the heat insulation support.

[0010] By setting up heat-insulating support components, which are connected to the bottom shell and the heating plate, direct contact between the heating plate and the bottom shell can be avoided, reducing the transfer of heat generated by the heating plate to the bottom shell, lowering the temperature of the bottom shell, avoiding the need for the bottom shell to be made of high-temperature resistant materials, reducing the production cost of the bottom shell, reducing the risk of bottom shell deformation, slowing down the aging rate of the bottom shell, extending the service life of the bottom shell, and optimizing the efficiency of heat transfer from the heating plate to the panel.

[0011] According to one embodiment of this application, the thermal insulation support includes a thermal insulation component and a support component;

[0012] The support member is connected to the bottom shell; the heat insulation member is sleeved on the support member and connected to the bottom shell; the heat insulation member is connected to the heating plate.

[0013] The thermal insulation support includes a thermal insulation component and a support component. The support component is connected to the bottom shell, and the thermal insulation component is sleeved on the support component and connected to the bottom shell. This allows the thermal insulation component to form a double fixation by being sleeved on the support component and connected to the bottom shell, reducing the probability of the thermal insulation component separating from the bottom shell due to vibration and improving the stability of the thermal insulation component.

[0014] According to one embodiment of this application, the thermal insulation support includes an elastic member, which is mounted on the thermal insulation member;

[0015] The elastic element abuts against the heating plate, so that the heating plate abuts against the bottom plate surface of the panel near the receiving cavity.

[0016] An elastic element is installed on the heat insulation component and abuts against the heating plate, so that the heating plate abuts against the bottom plate surface of the panel near the receiving cavity. The elastic deformation of the elastic element can absorb the stress of thermal expansion and contraction, avoiding rigid collision between the heating plate and the panel, and preventing damage to the heating plate and the panel.

[0017] According to one embodiment of this application, the heat insulation member includes a heat insulation portion, a connecting portion, and a mounting portion, wherein the mounting portion and the connecting portion are connected to the side of the heat insulation portion near the bottom shell;

[0018] The heat insulation part is sleeved on the support member, the connecting part is connected to the bottom shell, and the mounting part is used for mounting the elastic member.

[0019] The heat insulation component includes an insulation part, a connecting part, and a mounting part. The insulation part is directly fitted onto the support to form heat insulation, effectively preventing heat transfer from the heating plate to the bottom shell. The connecting part connects to the bottom shell, located on the side of the insulation part closest to the bottom shell. This facilitates connection between the connecting part and the bottom shell and ensures stable fixation of the heat insulation component to the bottom shell, preventing the insulation part from separating from the support due to vibrations and impacts of the ceramic cooker. This ensures a stable connection between the heat insulation component, the bottom shell, and the heating plate. The mounting part connects to the elastic element, ensuring the stability of the elastic element.

[0020] According to one embodiment of this application, the heat insulation portion covers the end of the support member away from the bottom shell.

[0021] The heat insulation section covers the end of the support member away from the bottom shell, which isolates the end of the support member away from the bottom shell from the heating plate. This completely prevents the high temperature of the heating plate from being transferred to the bottom shell through the support member, reducing heat loss, improving heating efficiency, and reducing the power consumption of the electric ceramic stove.

[0022] According to one embodiment of this application, the heat insulation part includes a first heat insulation sleeve and a second heat insulation sleeve, wherein the second heat insulation sleeve is connected to the side of the first heat insulation sleeve near the bottom shell;

[0023] The heating plate includes a plate body and a connecting ear disposed on the plate body, and the connecting ear is sleeved on the first heat insulation sleeve.

[0024] The outer periphery of the heat insulation part is provided with an outer stepped surface, which is located at the connection between the first heat insulation sleeve and the second heat insulation sleeve. It is used to restrict the movement of the connecting ear toward the side where the bottom shell is located, so as to limit the connecting ear to the first heat insulation sleeve.

[0025] The first heat insulation sleeve, the second heat insulation sleeve, and the outer stepped surface are provided to limit the connection ear, so that the connection ear is fitted on the first heat insulation sleeve. This prevents the heating plate from being subjected to excessive pressure that could compress the elastic element and cause the connection ear to move onto the second heat insulation sleeve. It also prevents interference between the heating plate and the structure on the bottom shell, thus avoiding damage to the heating plate and the bottom shell.

[0026] According to one embodiment of this application, the mounting part has a mounting groove, the opening of which faces the panel;

[0027] The elastic element is a spring, which is sleeved on the heat insulation part, and the end of the spring away from the panel is installed in the mounting groove.

[0028] A spring is fitted onto the heat insulation part, allowing the heat insulation part to guide the spring. The opening of the mounting groove faces the panel, and the end of the spring away from the panel is installed in the mounting groove. This allows the mounting groove to support the spring, enabling it to shorten when pressed by the heating plate and to provide a counterforce to the heating plate. This allows the heating plate to abut against the bottom plate surface of the panel near the receiving cavity. The spring is easy to install and remove, facilitating spring replacement. Furthermore, the mounting groove limits the bottom end of the spring, preventing large radial displacement of the spring in the heat insulation part and ensuring stable extension and contraction of the spring.

[0029] According to one embodiment of this application, the heat insulation part is provided with a heat insulation sleeve hole facing the bottom shell, and the heat insulation part is sleeved on the support member through the heat insulation sleeve hole;

[0030] The inner circumference of the heat insulation sleeve hole is provided with a positioning groove; the outer side wall of the support member is provided with a positioning plate;

[0031] When the heat insulation part is sleeved on the support member, the positioning plate is inserted into the positioning groove.

[0032] The positioning groove and positioning plate enable the positioning of the connecting part and the bottom shell, facilitating the connection between the connecting part and the bottom shell.

[0033] According to one embodiment of this application, the positioning plate extends along the extension direction of the support member.

[0034] The positioning plate is set along the extension direction of the support component to facilitate the positioning of the bottom shell and the heat insulation part, and the positioning plate can also strengthen the support component.

[0035] According to one embodiment of this application, the heat insulation part, the connecting part and the mounting part are integrally formed, the bottom shell is made of polypropylene, and / or the heat insulation component is made of polyphenylene sulfide.

[0036] The heat insulation part, connecting part, and mounting part are integrally molded, resulting in a small overall size of the heat insulation component, reducing the space occupied within the cavity, eliminating connection gaps and assembly clearances when separate parts are connected, reducing the risk of loosening due to vibration and thermal expansion and contraction, and ensuring the structural stability of the heat insulation component. The heat insulation component is made of polyphenylene sulfide, which has good high-temperature resistance and can effectively insulate heat. When the bottom shell is made of a high-temperature resistant material, the production cost of the bottom shell is high. The bottom shell can be made of polypropylene, which can reduce costs and the bottom shell is easy to mold. Attached Figure Description

[0060] An electric ceramic stove is a type of stove that uses infrared heating. Heat is generated by the nickel-chromium wires in the stove plate to perform various cooking tasks.

[0061] The main structure of an electric ceramic cooktop includes a bottom shell, a heating element, and a control panel. The heating element is typically housed within the bottom shell, with the control panel located at the top opening of the bottom shell. During operation, the heating element generates high temperatures that affect the control panel; however, this high temperature can cause thermal damage to the bottom shell. Therefore, the bottom shell is usually made of a heat-resistant material.

[0062] However, when the bottom shell is made of high-temperature resistant materials, the production cost of the bottom shell is high, and the bottom shell is prone to deformation and has a short lifespan.

[0063] Based on the aforementioned technical problems, the applicant has improved the structure of existing ceramic cooktops. In this embodiment, the ceramic cooktop may include a bottom shell, a panel, a heating plate, and a heat insulation support. The panel and the bottom shell together form a receiving cavity, and the heating plate and the heat insulation support are both located within the receiving cavity. The heat insulation support is connected to the bottom shell, and the heating plate is connected to the heat insulation support. This avoids direct contact between the heating plate and the bottom shell, reduces the transfer of heat generated by the heating plate to the bottom shell, lowers the temperature of the bottom shell, avoids the need for the bottom shell to be made of high-temperature resistant materials, reduces the production cost of the bottom shell, reduces the risk of bottom shell deformation, slows down the aging rate of the bottom shell, extends the service life of the bottom shell, and optimizes the efficiency of heat conduction from the heating plate to the panel.

[0064] The electric ceramic stove provided in this application will now be described with reference to the accompanying drawings and specific embodiments.

[0065] refer to Figure 1 , Figure 2 and Figure 3 This application provides an electric ceramic stove, which may include a bottom shell 1, a panel 2, a heating plate 3, and a heat insulation support 4.

[0066] Panel 2 and bottom shell 1 together form a receiving cavity 71. Heating plate 3 and heat insulation support 4 are both located within the receiving cavity 71. Heat insulation support 4 is connected to bottom shell 1. Heating plate 3 is connected to heat insulation support 4.

[0067] The electric ceramic stove provided in this embodiment of the application has a bottom shell 1 and a front panel 2, which together form a receiving cavity 71 for accommodating the heating plate 3 and the heat insulation support 4. The bottom shell 1 can be a square shell, a circular shell, or a shell of other shapes. The bottom shell 1 can be a shell with the receiving cavity 71 formed by integral molding, or it can be a shell assembled by a detachable connection of a lower shell 12 and a middle frame 13.

[0068] It should be noted that the bottom shell 1 has mounting holes 132 for mounting the panel 2. The shape of the mounting holes 132 can be any shape, such as round or square. Correspondingly, the panel 2 is adapted to the shape of the mounting holes 132, and the panel 2 covers the mounting holes 132, making the panel 2 a supporting component of the cookware. In this embodiment, the panel 2 can be a titanium crystal panel, a black crystal panel, or a ceramic panel; this embodiment does not impose any restrictions.

[0069] The electric furnace provided in this application embodiment, by setting a heat insulation support 4, which is connected to the bottom shell 1 and the heating plate 3 is connected to the heat insulation support 4, can avoid direct contact between the heating plate 3 and the bottom shell 1, reduce the transfer of heat generated by the heating plate 3 to the bottom shell 1, lower the temperature of the bottom shell 1, avoid the need for the bottom shell 1 to be made of high temperature resistant materials, reduce the production cost of the bottom shell 1, reduce the risk of deformation of the bottom shell 1, slow down the aging rate of the bottom shell 1, extend the service life of the bottom shell 1, and optimize the efficiency of heat conduction from the heating plate 3 to the panel 2.

[0070] In some embodiments, reference Figure 4 and Figure 5 The heat insulation support 4 may include a heat insulation component 41 and a support component 43. The support component 43 is connected to the bottom shell 1. The heat insulation component 41 may be fitted onto the support component 43 and is connected to the bottom shell 1. The heat insulation component 41 is connected to the heating plate 3.

[0071] The heat insulation support 4 includes a heat insulation component 41 and a support component 43. The support component 43 is connected to the bottom shell 1, and the heat insulation component 41 is sleeved on the support component 43 and connected to the bottom shell 1. This allows the heat insulation component 41 to form a double fixation by being sleeved on the support component 43 and connected to the bottom shell 1, reducing the probability of the heat insulation component separating from the bottom shell due to vibration and improving the stability of the heat insulation component.

[0072] In some embodiments, the heat insulation support 4 may further include an elastic element 42, which is mounted on the heat insulation 41. The elastic element 42 abuts against the heating plate 3, so that the heating plate 3 abuts against the bottom plate surface 21 of the panel 2 near the receiving cavity 71.

[0073] The elastic element 42 is installed on the heat insulation element 41 and abuts against the heating plate 3, so that the heating plate 3 abuts against the bottom plate surface 21 of the panel 2 near the receiving cavity 71. The elastic deformation of the elastic element 42 can absorb the stress of thermal expansion and contraction, avoid rigid collision between the heating plate 3 and the panel 2, and avoid damage to the heating plate 3 and the panel 2.

[0074] In some embodiments, reference Figure 5 and Figure 6 The heat insulation component 41 may include a heat insulation part 411, a connecting part 412, and a mounting part 413. The mounting part 413 and the connecting part 412 are connected to the side of the heat insulation part 411 near the bottom shell 1.

[0075] The heat insulation part 411 is sleeved on the support member 43, the connecting part 412 is connected to the bottom shell 1, and the mounting part 413 is used for the installation of the elastic member 42.

[0076] The heat insulation component 41 includes a heat insulation part 411, a connecting part 412, and a mounting part 413. The heat insulation part 411 is directly sleeved on the support member 43 to form heat insulation, effectively preventing the heat transfer from the heating plate 3 to the bottom shell 1 and reducing the temperature of the bottom shell 1. The connecting part 412 is provided to connect to the bottom shell 1. The connecting part 412 is connected to the side of the heat insulation part 411 near the bottom shell 1, which facilitates the connection between the connecting part 412 and the bottom shell 1 and can stably fix the heat insulation component 41 to the bottom shell 1, preventing the heat insulation part 411 from separating from the support member 43 due to vibration and impact of the electric ceramic stove, so as to ensure a stable connection between the heat insulation component 41, the bottom shell 1, and the heating plate 3. The mounting part 413 can be used to connect with the elastic member 42 to ensure the stability of the elastic member 42.

[0077] In some embodiments, the heat insulation portion 411 covers the end of the support member 43 away from the bottom shell 1, so that the heat insulation portion 411 can isolate the end of the support member 43 away from the bottom shell 1 from the heating plate 3, completely blocking the high temperature of the heating plate 3 from being transferred to the bottom shell 1 through the support member 43, reducing heat loss, improving heating efficiency, and reducing the power consumption of the electric ceramic stove.

[0078] In some embodiments, reference Figure 5 and Figure 6 The heat insulation part 411 includes a first heat insulation sleeve 4111 and a second heat insulation sleeve 4112. The second heat insulation sleeve 4112 is connected to the side of the first heat insulation sleeve 4111 near the bottom shell 1.

[0079] The heating plate 3 includes a plate body 31 and a connecting ear 32 disposed on the plate body 31. The connecting ear 32 may be disposed on the outer wall of the plate body 31.

[0080] The connecting ear 32 is fitted onto the first heat insulation sleeve 4111. The outer periphery of the heat insulation part 411 is provided with an outer stepped surface 4115, which is located at the connection between the first heat insulation sleeve 4111 and the second heat insulation sleeve 4112. It is used to restrict the movement of the connecting ear 32 toward the side where the bottom shell 1 is located, so as to limit the connecting ear 32 to the first heat insulation sleeve 4111.

[0081] A first heat insulation sleeve 4111 and a second heat insulation sleeve 4112 are provided to form an outer stepped surface 4115 at the connection between the first heat insulation sleeve 4111 and the second heat insulation sleeve 4112. The outer stepped surface 4115 can limit the connection ear 32, so that the connection ear 32 is fitted on the first heat insulation sleeve 4111, preventing the heating plate 3 from being compressed by a large pressure on the elastic element 42 and causing the connection ear 32 to move onto the second heat insulation sleeve 4112, avoiding interference between the heating plate 3 and the structure on the bottom shell 1, and avoiding damage to the heating plate 3 and the bottom shell 1.

[0082] Specifically, the outer stepped surface 4115 can face the panel 2, which can stably limit the connecting ear 32 and confine the connecting ear 32 to the first heat insulation sleeve 4111.

[0083] In some embodiments, the first heat insulation sleeve 4111 has a first outer surface located outside the first heat insulation sleeve 4111. The second heat insulation sleeve 4112 has a second outer surface located outside the second heat insulation sleeve 4112. Both the first and second outer surfaces are connected to the outer stepped surface 4115.

[0084] The area of ​​the surface enclosed by the cross-sectional contour of the first outer side is the first area, and the area of ​​the surface enclosed by the cross-sectional contour of the second outer side is the second area. The second area is larger than the first area, which makes the second heat insulation sleeve 4112 thicker than the first heat insulation sleeve 4111, thereby improving the strength of the heat insulation sleeve and enabling the heat insulation sleeve to be compatible with the connecting ear 32 of the heating plate 3.

[0085] In some embodiments, reference Figure 5 and Figure 6 The mounting part 413 has a mounting groove 4131, the opening of which faces the panel 2. The elastic element 42 is a spring, which is sleeved on the heat insulation part 411, and the end of the spring away from the panel 2 is installed in the mounting groove 4131.

[0086] A spring is fitted onto the heat insulation part 411, allowing the heat insulation part 411 to guide the spring. The opening of the mounting groove 4131 faces the panel 2, and the end of the spring away from the panel 2 is installed in the mounting groove 4131, allowing the mounting groove 4131 to support the spring. This allows the spring to shorten when pressed by the heating plate 3 and to provide a reverse force to the heating plate 3, causing the heating plate 3 to abut against the bottom plate surface 21 of the panel 2 near the receiving cavity 71. The spring is easy to install and remove, facilitating spring replacement. Furthermore, the mounting groove 4131 can limit the bottom end of the spring, preventing the spring from deviating significantly in the radial direction of the heat insulation part 411 and ensuring stable extension and contraction of the spring.

[0087] The mounting groove 4131 can be annular in shape, which can limit the end of the spring near the bottom shell 1 in all directions in the radial direction of the heat insulation part 411, improve the limiting effect, and prevent the spring from moving too much in the radial direction of the heat insulation part 411.

[0088] In some embodiments, reference Figure 8 The heat insulation part 411 is provided with a heat insulation sleeve hole 4113 that opens towards the bottom shell 1, and the heat insulation part 411 is sleeved on the support member 43 through the heat insulation sleeve hole 4113.

[0089] The inner circumference of the heat insulation sleeve hole 4113 is provided with a positioning groove 4116. The outer side wall of the support member 43 is provided with a positioning plate 431. When the heat insulation part 411 is sleeved on the support member 43, the positioning plate 431 is inserted into the positioning groove 4116.

[0090] The positioning groove 4116 and the positioning plate 431 are provided to enable the positioning of the connecting part 412 and the bottom shell 1, which facilitates the connection between the connecting part 412 and the bottom shell 1.

[0091] Specifically, the positioning plate 431 extends along the extension direction of the support member 43, which facilitates the positioning of the bottom shell 1 and the heat insulation part 411, and the positioning plate 431 can strengthen the support member 43.

[0092] In some embodiments, the heat insulation part 411, the connecting part 412, and the mounting part 413 are integrally formed. The bottom shell 1 may be made of polypropylene (PP), and / or the heat insulation part 41 may be made of polyphenylene sulfide (PPS).

[0093] The bottom shell 1 can be injection molded. Polypropylene has good injection molding properties, which facilitates the molding of the bottom shell 1. Polyphenylene sulfide has good high temperature resistance and can be connected between the bottom shell 1 and the heating plate 3 to reduce the heat transfer from the heating plate 3 to the bottom shell 1, thereby lowering the temperature of the bottom shell 1.

[0094] The heat insulation part 411, the connecting part 412, and the mounting part 413 are integrally molded, resulting in a small overall size of the heat insulation component 41. This reduces the space occupied within the receiving cavity 71, eliminates connection gaps and assembly clearances that occur when components are connected separately, reduces the risk of loosening due to vibration and thermal expansion and contraction, and ensures the structural stability of the heat insulation component 41. The heat insulation component 41 is made of polyphenylene sulfide (PPS), which has good high-temperature resistance and can effectively insulate and reduce the temperature of the bottom shell 1. If the bottom shell 1 is made of a high-temperature resistant material, the production cost of the bottom shell 1 will be high. Using polypropylene as the material for the bottom shell 1 can reduce costs, and the bottom shell 1 is easy to mold.

[0095] In some embodiments, reference Figure 8 The heat insulation sleeve hole 4113 includes a first sleeve hole 41131 and a second sleeve hole 41132. The second sleeve hole 41132 is located on the side of the first sleeve hole 41131 near the bottom shell 1, and the first sleeve hole 41131 and the second sleeve hole 41132 are connected. The end of the support member 43 near the panel 2 is located in the second sleeve hole 41132.

[0096] The heat insulation part 411 includes an inner stepped surface 4117. The inner stepped surface 4117 can face the bottom shell 1 and can be located at the end of the second sleeve hole 41132 near the bottom shell 1. The end of the support member 43 near the bottom shell 1 can be located inside the second sleeve hole 41132 and can abut against the inner stepped surface 4117, which can improve the stability of the heat insulation part 41.

[0097] The end of the support member 43 near the panel 2 can also be located inside the first sleeve hole 41131, so that the support member extends long enough into the heat insulation sleeve hole 4113, further preventing the heat insulation member 41 from falling off the support member 43 and improving the stability of the heat insulation member 41.

[0098] In some embodiments, reference Figure 6 , Figure 7 and Figure 8 The bottom shell 1 is provided with a fixing post 121. The fixing post 121 is connected to the connecting part 412. The fixing post 121 and the connecting part 412 can be detachably fixed. Specifically, the fixing post 121 is provided with a fixing hole 1211.
