Title of Invention: Intaglio Induction Cooker

[1] Technical field

[2] The present invention relates to an induction cooker, and more particularly to a concave disk type induction cooker.

[3] Background Art

[4] Induction cooker is a cooker that uses the principle of electromagnetic induction to heat food. It is mainly composed of the casing part and the wire boring plate set inside the casing. When the pot is placed on the induction cooker casing, the wire 圏The alternating magnetic field generated after energization, the pot cutting the alternating magnetic field lines, will produce alternating current in the bottom metal part, the alternating current causes the metal molecules of the pot to move at high speed and irregularly, and the molecules collide with each other and generate heat by friction. It can be used for cooking. Since the heat source of the induction cooker comes from the bottom of the cooker instead of the induction cooker itself, its thermal efficiency is much higher than that of traditional cookware, and it has the advantages of no open flame, smokeless dust, harmless gas, good safety, etc. It is more and more popular among consumers.

[5] At present, there is a type of concave induction cooker different from the flat type. The heating panel above the seat body has a downward concave shape, and the concave inlet is provided with a bearing capacity for supporting the cookware. The induction cooker is suitable for the traditional The bottom part is a circular arc convex pot. When the pot is placed on the induction cooker, the bottom can be placed in the concave inlet, and the side wall is supported by the support position, so that the pot can be stably placed on the induction cooker, currently China Most of the households use the traditional pots with such circular arcs, and the pots are more convenient for cooking, which is in line with Chinese cooking habits. Therefore, the concave-plate induction cooker has more in the Chinese market. Great promotion value.

[6] As mentioned above, the heating efficiency of the induction cooker depends on the effective area affected by the magnetic field generated by the wire pan of the induction cooker at the bottom of the cooker. For the concave induction cooker on the present surface, the wire is mostly flat. Laying under the concave inlet, or around the concave entrance, the wire-and-concave structure; unlike the flat-plate induction cooker, the concave-type induction cooker uses the flat wire-type arrangement, due to the shape of the wire-shaped disk If the bottom of the pot is not adapted, the heat generation area of the pot will be small, the thermal efficiency will be greatly reduced, the electric energy will not be effectively utilized, the power consumption is large and the cooking effect is poor, and there is no competitive advantage in the market; Induction cooker with setting mode needs to take into account the position of the coil and the position of the bearing capacity of the pot placed on the concave inlet. In order to improve the thermal efficiency, the load-bearing position of the current product is set lower, or the arc is used. In the case of surface contact, the effective diameter of the coil disk is generally greater than the distance of the bearing capacity, that is, the bearing capacity is located within the effective area of the coil disk. Such a setting is generally considered to be the most reasonable in the industry. However, the concave disk type induction cooker of this type is constructed. At work, the bottom of the pot is radiated by the coil disk, and the support position is located at the hottest part of the bottom of the pot. Usually, the temperature at the bottom of the cooking pot is higher than 500 °C, so the load-bearing position of the bottom of the pot needs to be firm and durable. Impact, good load-bearing strength, and also need to meet the requirements of normal use under high temperature conditions, so that the material requirements are high during manufacturing, the process is difficult, the product cost is greatly increased, and the use effect is poor, and the service life is short. Compared with the flat-plate induction cooker, there is no better market competitive advantage.

[7] Summary of the invention

[8] An object of the present invention is to provide a concave disk type induction cooker which has high heating efficiency and can reduce material requirements, has a reasonable structure, a good use effect, and a long service life.

[9] The technical solution adopted by the present invention to solve the technical problem thereof is:

[10] a concave disk type induction cooker comprising a casing, wherein the casing is provided with a concave inlet, and a wire boring disk is arranged below the concave inlet inside the casing, and the concave inlet is a circular opening adapted to the bottom of the cookware. The wire reel is wound around the concave inlet to be arranged to match the shape of the bottom of the pot, and the concave position of the pot is provided on the concave inlet, and the height position of the weight of the pot is not lower than the line The plate is from the top of the top four.

[11] The beneficial effects of the invention are: The installation structure of the wire reel of the invention is reasonable, and the heating area of the pot placed on the concave inlet is ensured, so that the use effect is good, the efficiency is high, and the usage requirements of the people are satisfied, and the same The weight-bearing position of the pot set provided by the invention is disposed outside the heat-generating effective area, so that the material which is resistant to high temperature and impact resistance is saved even at the same time without affecting the heating area, so that the cost is greatly reduced and the service life is long, thereby greatly increasing the product. Market competitiveness.
