Description

A new type of heating plate

technical field

The utility model relates to the field of electric heating, in particular to a novel heating plate.

Background technique

Existing heating plates on the market include electric furnaces, electric tea stoves, electric cooking pots, etc. These traditional heating plates are generally divided into two types: one is a pressure tube heating plate, and the other is a wire laying heating plate. The pressure tube heating plate is composed of a heating tube and a metal shell, and most of the shells are made of aluminum alloy or cast iron plate. This pressure tube heating plate directly presses the heating tube into the shell plate, and the internal temperature is very high when it is working, and the heating tube will fall off or break after the product is turned on and off many times, which will affect its service life. Another type of wire-laid heating plate is a structure in which heat-insulating insulating powder is pressed into a cast iron plate, the heating wire is spread inside, and then covered with heat-insulating clothing. The internal temperature of this product is lower than that of the previous pressure tube heating plate and the life is better, but relatively speaking, the structure is complex, the process is numerous, the process is complicated, the product production cycle is long, the energy consumption is high, the moisture discharge temperature is high, and the heat utilization rate is high. Low, high manufacturing and labor costs, and long-term storage of heat insulation powder will easily absorb moisture and cause the product to fail the withstand voltage test.

Utility model content

The technical problem to be solved by the embodiment of the utility model is to provide a new heating plate with high efficiency and high reliability.

The new heating plate includes a cast iron plate, a heat pipe, and a heat insulating powder layer. The upper surface of the cast iron plate is provided with a groove for placing the heat pipe, and the upper surface of the cast iron plate is sprayed with a coating layer. The upper surface of the cast iron plate is provided with a spiral groove with the center point of the cast iron plate as a circle, the heating pipe is a spiral heating pipe, and the spiral heating pipe is engaged in the spiral In the groove, one of the lead posts is arranged on the first spiral groove near the center of the cast iron plate blank, and the other lead post is arranged in the outermost spiral groove.

The flattened thickness of the cast iron plate blank is 14-15mm, and the cast iron plate blank is made of gray cast iron with a thickness of 2.6-2.8mm.

The upper surface of the cast iron plate blank is in the shape of a corrugated thread, and the depth of the groove is 5mm, which is used to closely cooperate with the heating pipe.

The heating tube is made of copper-plated iron tube with a diameter of 6.6 mm. The heating element in the heating tube is composed of a spiral heating wire wound by iron-chromium-aluminum alloy wire. The middle of the heating tube is filled with medium-high temperature magnesium oxide Insulation materials.

The coating layer is a nano inorganic ceramic coating with a thickness of 25-50um.

The heat insulation layer is a composite material layer composed of quartz sand and kaolin materials, with a thickness of 2-4mm.

Implementation of the utility model embodiment has the following beneficial effects:

The embodiment of the utility model is a new type of heating plate, which is structurally equipped with a cast iron plate blank, a heating pipe and a heat insulating powder layer, so that the heating body has double protection. Such a new heating plate simplifies the production process, reduces the process of high temperature sintering and bottom pressing and delamination, shortens the production cycle time by 40%, reduces the production workers by about 60% under the same output, and reduces production consumption And labor costs, the total cost decreased by about 7%. In terms of performance, the product solves the problem of failing the pressure test caused by long-term storage in humid weather due to moisture absorption. At the same time, the direct heat transfer efficiency of the plate surface is higher, and the boiling time is also improved, which is about 1 minute faster than the traditional heating plate. . The change in structure prolongs the service life of the product by 30%. Nano-inorganic ceramic coating is used on the surface, which greatly increases the anti-corrosion, anti-rust and high temperature resistance of the product. In the working state, the heating element in the heating plate uses the iron-chromium-aluminum alloy resistance wire with good heating performance and low cost. After being energized, it directly acts on the cast iron plate blank of the heating plate through the heating tube, and the heat transfer efficiency is higher. Cast iron The plate blank is made of gray cast iron with a thickness of 2.6 - 2.8 mm, which is not easy to deform and crack under high temperature. The surface layer has a wavy thread shape, which increases the heating area and better transfers heat to the pot. The inner layer of the disk has a heat insulation layer to keep heat, so that the heat energy can be better stored in the disk, reducing the loss of heat energy and having better energy consumption efficiency.
