Description

Technical Field

[0001] This utility model relates to the field of electromagnetic cooking stove technology, and more specifically, to a floor-mounted cooking stove with zoned control. Background Technology

[0002] Currently used electromagnetic wok cookers work by generating an alternating magnetic field through an electromagnetic coil. When a pot made of magnetic material is placed in this alternating magnetic field, the bottom surface of the pot cuts through the alternating magnetic lines of force, generating alternating eddy currents at the bottom of the pot. These eddy currents cause the metal atoms at the bottom of the pot to move at high speeds and randomly, thus generating heat energy and heating the food inside the pot. However, the resistance and magnetic reluctance of the electromagnetic coil and magnetic strip on the electromagnetic coil differ significantly between room temperature and high temperature. As the temperature increases, the resistance and magnetic reluctance increase, leading to a gradual increase in losses in the electromagnetic coil and magnetic strip. This also causes the temperature of the electromagnetic coil and magnetic strip to rise, resulting in a decrease in the thermal efficiency of the electromagnetic coil as the temperature increases.

[0003] In existing technologies, electromagnetic coils are often installed at the bottom of the pot base. Electromagnetic coils at the bottom of the pot can only heat the bottom area, resulting in poor heating effect in the upper part of the pot and causing serious waste of resources. Furthermore, since electromagnetic coils are often installed at the bottom of the pot base, the heat is concentrated in this area, which causes the electromagnetic coil at the bottom of the pot base to have a reduced thermal efficiency due to the increased temperature, resulting in a decrease in the heating efficiency of the pot body through the electromagnetic coil.

[0023] Example

[0024] This utility model provides a zone-controlled floor stove, such as... Figures 1-5As shown, the system includes a support platform 2, which is cylindrical in shape and has an installation chamber. The top of the support platform 2 has a circular opening that communicates with the installation chamber. A pot body 5 is installed inside the installation chamber, with its outer edge overlapping the top of the support platform 2. A support structure adapted to the pot body 5 is installed inside the installation chamber. A second induction coil 8 is installed at the bottom of the support structure, heating the bottom of the pot body 5. A first induction coil 7 is arranged around the outer wall of the support structure, heating the upper-middle area of ​​the outer side of the pot body 5. A control panel 9, a PLC controller (existing technology), is located on the outer wall of the support platform 2. Both the first induction coil 7 and the second induction coil 8 are electrically connected to the control panel 9. With the above structure, the operator can control the first induction coil 7 or the second induction coil 8 to be turned on independently via the control panel 9, or to turn on the first induction coil 7 and the second induction coil 8 simultaneously. This avoids the problem of heat concentration in the bottom area of ​​the pot base, which would cause the electromagnetic coil located at the bottom of the pot base to reduce its thermal efficiency due to increased temperature, thus reducing the heating efficiency of the pot body 5 through the electromagnetic coil. Furthermore, the second induction coil 8 can heat the upper middle area of ​​the pot body 5, improving the thermal energy utilization rate of the above structure during use.

[0025] In some technical solutions of this utility model, the support structure includes a limiting ring 6, a fixed base 15, and several arc-shaped connecting members 10. The fixed base 15 is disc-shaped, with a hollow area to enhance heat dissipation. The arc-shaped connecting members 10 have a "U"-shaped cross-section, which strengthens their structural strength. Several connecting members 10 are arranged around the side wall of the fixed base 15, with a total of 6 connecting members 10. The free ends of all connecting members 10 are connected to the limiting ring 6, and the second induction coil 8 is mounted on the fixed base 15. The cage-like structure formed by the above structure can match the shape of the pot body 5, better transferring the heat energy generated by the first induction coil 7 and the second induction coil 8 to the pot body 5, thus improving the efficiency of heat energy utilization.

[0026] The limiting ring 6, the fixed base 15, and several arc-shaped connectors 10 are all made of high-temperature resistant plastic.

[0027] In some technical solutions of this utility model, mounting grooves 16 are provided on the side walls of the fixed base 15 and several arc-shaped connectors 10. The mounting groove 16 is the C-shaped area of ​​the connector 10, and the magnetic poles adapted to the first induction coil 7 and the second induction coil 8 can be installed in the mounting groove 16, which saves space. The mounting groove 16 can also be a hollow area of ​​the fixed base 15.

[0028] In some technical solutions of this utility model, a retaining ring 14 that abuts against the limiting ring 6 is installed on the inner wall of the installation chamber. This facilitates the quick installation of the support structure in the installation chamber, prevents the support structure from swaying freely in the installation chamber, and allows the outer edge of the pot body 5 to overlap with the limiting ring 6, which can reduce the relative distance between the support structure and the pot body 5, and better transfer the heat energy generated by the first induction coil 7 and the second induction coil 8 to the pot body 5, thereby improving the efficiency of heat energy utilization.

[0029] In some technical solutions of this utility model, a tabletop 1 is installed on the support platform 2. This facilitates the placement of items when using the above-mentioned stove structure, providing convenience for users to cook food using the stove.

[0030] In some technical solutions of this utility model, a smoke exhaust structure for smoke exhaust is installed on the support platform 2.

[0031] In some technical solutions of this utility model, the smoke exhaust structure includes an installation ring 4 installed on the support platform 2, a smoke exhaust chamber 12 is opened in the installation ring 4, and a plurality of smoke holes 13 are arranged around the inner side wall of the installation ring 4. An exhaust device 11 is provided on the support platform 2, and a pipe 17 communicating with the smoke exhaust chamber 12 is provided on the input end of the exhaust device 11.

[0032] The smoke exhaust structure can exhaust the smoke generated during cooking from the top of the support platform 2, preventing the smoke from obstructing the user's view while cooking and improving the user experience.

[0033] The working principle of the exhaust structure is as follows: When cooking food, the exhaust device 11 is activated first. The exhaust device 11 generates negative pressure in the exhaust chamber 12. The smoke generated by cooking food enters the exhaust chamber 12 from the inner wall of the mounting ring 4, which is surrounded by several smoke holes 13. Then, it is guided by the exhaust device 11 to the exhaust duct to the outside.

[0034] In some technical solutions of this utility model, the bottom of the support platform 2 is provided with several support legs 3. The number of support legs 3 is 3, which can raise the horizontal height of the support platform 2 and facilitate the placement and transportation of the support platform 2 in the later stage.

[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
