Description

Technical Field

[0001] The utility model relates to a combined knob and an electric ceramic stove using the knob, belonging to the technical field of electrical appliances. Background Art

[0002] At present, household appliances on the market, such as electric ceramic stoves, use knobs, timers and thermostats together. Since the knobs are in direct contact with the thermostats and timers, and the thermostats are high-temperature parts, the knobs must be made of waterproof and high-temperature resistant materials. In the current industry, knobs are usually made of fireproof PP or nylon materials, but the surface treatment performance of these two materials is not good, whether it is the surface gloss or the performance of other post-processing processes. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a combined knob and an electric ceramic stove using the knob. The knob has good surface treatment performance while being resistant to high temperatures, and can solve the deficiencies of the prior art.

[0004] The technical solution of the utility model is: a combined knob, including an inner insert and an outer insert, the inner insert is injection molded by high temperature resistant material, and has a connection structure that cooperates with high temperature parts, the outer insert is injection molded by material with good surface post-treatment performance, and is embedded outside the inner insert and fixedly connected with the inner insert.

[0005] Furthermore, the embedded part is injection molded by PP material, and the embedded part is injection molded by ABS material.

[0006] Furthermore, the inner embedded part and the outer embedded part are fixed by adhesive bonding.

[0007] Furthermore, the outer insert is cylindrical or truncated cone-shaped, and has an anti-slip structure on the outer peripheral wall.

[0008] An electric ceramic stove comprises a body with a built-in heating component, a temperature controller and a timer are installed on the body, and the temperature controller comprises the above-mentioned combined knob, and the operating rod of the temperature controller passes through the timer and is connected to the connection structure of the knob embedded part.

[0009] Furthermore, handles are provided on both sides of the body.

[0010] Further, the main body comprises a middle shell bracket and a middle shell. The middle shell is a frame-like structure with two ends open and is surrounded by sheet metal. The middle shell bracket is welded and fixed to the inner side of the middle shell.

[0011] By implementing the utility model, the knob includes an inner insert and an outer insert which are fixedly connected inside and outside. The inner insert is injection molded from high temperature resistant material and can be directly connected to high temperature parts. The outer insert is injection molded from material with good surface post-processing performance and can undergo subsequent spraying, electroplating and other post-processing processes. The knob has better appearance quality while meeting the high temperature resistance performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] As shown in the figure: an inner insert 1; an outer insert 2; a protrusion 3; a heating component 5; a body 6; a thermostat 7; a timer 8; a handle 9; a middle shell bracket 10; a middle shell 11; a heat sink 12; an anti-slip support foot 13; and a microcrystalline glass 14. DETAILED DESCRIPTION

[0016] Embodiments of the present utility model: Figures 1 to 3 As shown, a combined knob includes an inner insert 1 and an outer insert 2. The inner insert 1 is injection molded by a high temperature resistant material, such as fireproof PP in the present application, and has an inner end with a connection structure that matches a high temperature part, and an outer end with a non-circular protrusion 3; the outer insert 2 is injection molded by a material with good surface post-treatment performance, such as ABS in the present application, and has a concave cavity for embedding the inner insert 1. After the inner insert 1 is installed in the concave cavity of the outer insert 2, the inner end is exposed to the outside. The inner insert 1 and the outer insert 2 are fixed by gluing. Since the inner insert 1 has a non-circular protrusion 3, on the one hand, the gluing area is increased, and on the other hand, it plays a role in limiting and preventing relative rotation, so that the connection between the two is more firm.

[0017] As a preferred embodiment, the outer insert 2 is cylindrical or truncated cone-shaped, which is convenient for rotation operation, and the outer peripheral wall is convex and concave, which has an anti-slip effect.

[0018] An electric ceramic stove comprises a body 6 with a heating component 5 therein, the heating component 5 is a heating ring, a thermostat 7 and a timer 8 are mounted on the body 6, wherein the timer 8 is plugged into a joystick of the thermostat 7, a connection structure arranged on an inner insert 1 is a D-shaped hole matched with the joystick, a knob is connected to the joystick of the thermostat 7 through the D-shaped hole of the inner insert 1, so as to realize the rotation operation of the timer 8 and the thermostat 7, an outer insert 2 is not directly in contact with the timer 8 and the thermostat 7, ABS injection molding is adopted, and other post-processing processes such as spraying and electroplating can be performed later, so that the knob has better appearance quality while meeting the high temperature resistance performance.

[0019] As a preferred embodiment, handles 9 are provided on both sides of the body 6 to facilitate the transportation of the electric ceramic stove.

[0020] As a preferred embodiment, the main body 6 includes a middle shell bracket 10 and a middle shell 11. The middle shell 11 is a frame-shaped structure with open ends and is surrounded by sheet metal. The middle shell bracket 10 is fixed to the inner side of the middle shell 11 using seamless welding technology, thereby making the product more reliable. The 9 hands are installed on both sides and the inner side of the middle shell 11 to fix the middle shell bracket 10. The microcrystalline glass 14 is embedded in the upper end of the middle shell 11, and the lower end of the middle shell 11 is installed with a matching heat sink 12 for easy assembly. Anti-slip support feet 13 are provided at the four corners on the back of the heat sink 12, which has an anti-slip support effect.
