Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

In this embodiment, as shown in FIG. 1 , a multi-purpose heating plate includes an electric heating tube 1 and a square heat conducting plate 2 .

The electric heating pipes include spiral first electric heating pipes 11 , second electric heating pipes 12 , third electric heating pipes 13 and fourth electric heating pipes 14 to evenly divide the heat conduction plate into four heating zones. When the heating plate is heating the small cooker, the small cooker only needs to be placed in any heating zone, and the electric heating tube in the corresponding heating zone will work, so as to maximize the contact area between the heating zone and the cooker, and improve the utilization rate of heat energy. The remaining electric heating tubes do not work, so as to avoid heating the area too large, and the small cooking utensils cannot be in contact with all the heating areas, wasting the generated heat. The heating plate can heat four cooking utensils at the same time, and the cooking utensils are placed in four different heating zones for heating, and the heating zones do not interfere with each other. When the heating plate heats relatively large cooking utensils, the cooking utensils can be placed on the heating plate, and all the electric heating tubes work to increase the heating power and the heating rate is fast.

As shown in FIG. 2 , the heat conduction plate 2 includes an upper plate body 21 and a lower plate body 22 that can be fastened and installed to accommodate the inner cavity of the electric heating tube. The lower plate body is provided with a heat insulating plate 221 that separates the heating area. As shown in FIG. 3 , a heating area line 211 for distinguishing heating areas is provided on the surface of the upper plate, and a pressure sensing device 222 is provided at the lower end of the heat conduction plate. The heat insulation board 221 separates each heating zone, and when only one electric heating tube is working, it prevents the generated heat from being transferred to other heating zones, which wastes heat energy. The heating zone line on the upper plate separates each heating zone. When people are heating food, they can place the cooking utensils according to the heating zone line, so that the cooking utensils can be in contact with the heating zone as much as possible to improve the utilization rate of heat energy. The pressure sensing device senses the weight of the object to be heated on the heating plate, and when the weight of the object to be heated exceeds a set value, the pressure sensing device will display an overweight message. On the one hand, the pressure sensing device prevents the object to be heated from being too heavy to crush the heating plate, on the other hand, it prevents too much heated liquid from overflowing and scalding people when boiling, or the liquid flows into the power supply to cause electrical short-circuit and burn out.

It also includes an electric heating plate base 3 carrying a heat conduction plate, and a temperature control switch 33 for sensing temperature is arranged in the electric heating plate base. The temperature control switch senses the temperature of the heating plate to prevent the electric heating tube from burning out due to the high temperature.

As shown in accompanying drawing 4, the first electric heating pipe 11, the second electric heating pipe 12, the third electric heating pipe 13 and the fourth electric heating pipe 14 are connected in parallel, the first electric heating pipe, the second electric heating pipe, the third electric heating pipe and the fourth electric heating pipe The tubes do not interfere with each other when they are heated, and they can be heated at the same time or separately.

The electric heating tube is connected in series with the LED display lamp 31 and the switch 32 on the base of the electric heating plate, the working state is displayed on the LED display lamp, and the switch controls the work of the electric heating tube.

The cross section of the electric heating tube is a circle with a diameter of 35-65 μm, and the heat insulation board is a vacuum insulation board with a thickness of 20-45 μm.

The pressure sensing device 222 includes a guide shaft (not marked in the figure) connected to the heat conduction plate, a spring (not marked in the figure) sleeved on the guide shaft, and a pressure switch 2221 arranged at the lower end of the spring. The guide shaft supports the heat conduction plate, and the spring transmits the pressure of the heat conduction plate to the pressure switch, and the pressure switch changes the on-off state according to the pressure transmitted by the spring. The pressure sensing device and the temperature control switch are connected in parallel with the electric heating tube.

The pressure switch is connected in series with the LED display lamp and the resistor arranged on the base of the electric heating plate. When the weight of the object placed on the heating plate exceeds the set value, the pressure switch is closed and the LED display light is on.

The number of guide shafts is not less than 4, and the material of the upper plate is aluminum alloy.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the present invention and not to limit them. Although the embodiments of the present invention have been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should It is understood that modifications or equivalent replacements can still be made to the technical solutions of the embodiments of the present invention, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
