Description

Technical Field

[0001] This utility model relates to a household appliance, and more particularly to an electric stove panel and its control switch structure. Background Technology

[0002] Electric stoves are common household appliances, available in electromagnetic and resistance types. Traditional resistance heating products have a relatively simple design, using a heating wire and a mechanical knob for control. However, during use, heat dissipates more from the periphery, while the heat concentrates in the center, easily leading to localized overheating. These products generally lack temperature indicators or precise temperature settings to reduce production costs. There are also safety concerns, which can shorten their lifespan.

The furnace body is embedded above the base and has a heating part that is higher than the top surface of the panel. A protective ring is sleeved on the outside of the heating part. The heating part is provided with evenly spaced positioning blocks and heating wires surrounding the positioning blocks. The heating wires are arranged continuously along a wavy path. A switch assembly is provided on the top surface of the panel or the side of the base. The switch assembly includes at least a display and a switch controller. The heating wires have a spiral structure.

[0005] The base can be square or circular.

[0009] The positioning block has an arc-shaped structure, and the notches between adjacent positioning blocks are arranged facing each other.

[0010] The positioning blocks are arranged at the same center, and the diameter of the positioning blocks increases sequentially from the inside to the outside.

[0019] Figure 5 This is a schematic diagram of the structure of Embodiment 3 of this utility model. Detailed Implementation

[0020] Example 1: As Figures 1-3 As shown, an electric furnace panel and its control switch structure include a base 1, a panel 2, and a furnace body 3. The furnace body 3 is embedded above the base 1 and has a heating element 4 that is higher than the top surface of the panel 2. A protective ring 5 is fitted around the heating element 4. The heating element 4 keeps the heating point relatively far away from the electronic circuit, improving service life, reducing the failure rate, and ensuring safety to a certain extent. Simultaneously, the protective ring 5 serves as heat insulation, reducing heat loss around the heating point. The heating element 4 contains evenly spaced positioning blocks 6 and heating wires 7 surrounding the positioning blocks 6, with the heating wires 7 arranged continuously along a wavy path. The layout of the positioning blocks 6 resembles a wireless network icon and is symmetrically designed to facilitate the encirclement of a single heating wire 7. This arrangement of the heating wires 7 securely binds them between the positioning blocks 6. Furthermore, the even arrangement of the heating wires 7 promotes uniform heat dissipation. The continuous arrangement of the heating wires 7 further contributes to the stability and reliability of the heating circuit, reducing the likelihood of localized overheating, melting, or other issues affecting operation. The top surface of the panel 2 is equipped with a switch assembly, which includes at least a display 8 and a switch controller 9. The heating wire 7 has a spiral structure. Compared with the direct control circuit of the switch in traditional products, various modules are integrated into the switch controller 9 here, and the display 8 displays the temperature or other important parameters in real time.

[0021] The base 1 has a square structure, which resembles the appearance of an induction cooker, making it simple and aesthetically pleasing. Its overall height is also relatively small compared to other embodiments. The protective ring 5 has several evenly distributed ventilation holes 10. These holes are designed to prevent localized overheating and also allow for effective temperature control via the switch. The switch assembly also includes a mounting bracket 11, which has a box-shaped structure and is integrally molded from ceramic material. The bracket 11 is designed for easy installation and provides some insulation, dirt protection, and dust prevention.

[0022] The switch controller 9 includes a knob and a circuit board. If it is a push-button switch, it should have functions such as press to turn on, press again to turn off, and press and hold for 3 seconds for timing. This is only a supplement to other switch types. The mounting bracket 11 has a round hole 12 corresponding to the knob, a square hole 13 corresponding to the display 8, and an oval straight hole 14 for installation and connection. The circuit structure of the switch controller 9 is a mature technology and can utilize a circuit similar to that of an induction cooker. The difference is that a knob is still used here, which will not be elaborated or limited in detail here. It should be noted that a knob has better operational stability than multi-point touch screen control. Here, the round hole 12 is for the knob to pass through for installation, the square hole 13 is for the display 8 to expose key information, and the oval straight hole 14 is an oval hole with smooth middle and elliptical ends, which facilitates position adjustment and installation.

[0023] The positioning block 6 has an arc-shaped structure, with the notches of adjacent positioning blocks 6 facing each other. The shape of the positioning block 6 facilitates the arrangement of the heating wire 7 along the arc, reducing unnecessary bends. The positioning blocks 6 are arranged concentrically, with their diameters increasing from the inside out. This concentric arrangement effectively saves space, optimizes the design, and ensures full heating and utilization. The heating section 4 also has a circular deflector block in the center, which, unlike the other positioning blocks 6, is located at the center and has a significant change in direction. This circular block also serves as the core support for the pot body, and its strength meets design requirements, ensuring long-term use. The panel 2 is made of glass or ceramic material, heat-set at high temperatures, providing high-temperature resistance and insulation to meet design requirements. The circuit board has at least one temperature control module for adjusting the temperature range. In this embodiment, it can be designed so that the temperature does not jump at 2200W, drops to 1000W below 2200W, and rises to the adjusted temperature below 1000W. This ensures the temperature remains within the set range. It should be noted that temperature signals can be transmitted through temperature sensors, and adjustment commands can be issued based on step changes. This is a mature technology, and will not be elaborated or limited here.

[0024] Example 2: As Figure 4As shown, unlike Embodiment 1, the furnace body 3 is entirely situated on the panel 2, while the height of the protective ring 5 is greater than the height of the furnace body 3. The protective ring 5 covers the sides of the furnace body 3, and a support strip 15 is provided at the top of the protective ring 5. Visually, it occupies less countertop space, provides sufficient heat and electrical separation, and meets the individual needs of some users.

[0025] Example 3: As Figure 5 As shown, unlike embodiments 1 and 2, the base 1 has a switch assembly on its side. This side placement further reduces oil splattering and prevents obstruction of vision during food preparation.
