Abstract
The invention relates to an electromagnetic heating ceramic container with a built-in high-frequency electromagnetic signal inductor. According to the electromagnetic heating ceramic container with the built-in high-frequency electromagnetic signal inductor, a round iron sheet or a round stainless steel sheet is embedded at the bottom of the ceramic container to form an internal embedded layer and thus to form a sandwich plate-like structure at the bottom of the ceramic container, which comprises an upper layer, a middle layer and a lower layer; the upper and the lower layers of the bottom of the ceramic container are made of common ceramic materials, and the middle layer is the embedded iron sheet or stainless steel sheet. The diameter of the round iron sheet or the round stainless steel sheet is more than or equal to 10 cm and less than or equal to 85% of the diameter of the bottom of the ceramic container. The ceramic container made by the method provided by the invention is simple in fabrication process, low in cost and convenient to transport. The ceramic container is corrosion-proof and easy to clean, can be directly placed on and heated by an induction cooker without the risk of cracking, and can replace the commonly-used glass beakers and water bathes in laboratories as well as soup cookers in daily life.
Description
Technical field
The present invention relates to a kind of pottery, is the pottery that a kind of built-in high-frequency electromagnetic signal inductor can be used Electromagnetic Heating specifically.
Background technology
China is one of several time-honored ancient civilized countries in the world, and many major contributions have been made in the progress and development of human society.Obtained achievement on ceramic technology and art especially has special significance.Utilize ceramic bowl that potter's clay burns paper as sacrificial offerings, alms bowl, cylinder etc. as our articles for daily use, corrosion-resistant, cost is low, and manufacture craft is simple, is every indispensability, deeply is subjected to liking of broad masses.But along with popularization and the extensive use of electromagnetic oven, common Household ceramic bowl also has its limitation, and it can not be placed directly in heating or insulation on the electromagnetic oven, and this brings many inconvenience to the user.
But glassware has good corrosion resistance and the heating property under the certain condition, in the chemical classes laboratory, people often adopt the beaker of the middle-size and small-size capacity of being made by glass to be used for the heating of liquid by alcolhol burner, bring great convenience for various chemical research, the method is historical by the use in more than 200 years so far.Yet glass beaker also has great topical type.One, in order to prevent the explosion of beaker heating process, it is as far as possible thin that wall of cup must be made, and reaches the purpose that is heated evenly, and has contradiction between the Bao Yuda, and the beaker capacity is larger, uses and cleaning process is easier breaks.Its two, alcohol is inflammable dangerous material, simultaneously, all kinds of chemical laboratories store various combustible and explosive articles, alcolhol burner just becomes the potential dangerous matter sources in laboratory naturally, not general in the reality have the event of breaking alcolhol burner initiation fire and blast to occur.
Electromagnetic oven is the electrical heated appliance that utilizes electromagnetic inductive heating principle to make.Partly formed by high-frequency induction heating coil (being magnet exciting coil), RF power conversion equipment, controller and ferromagnetic material the bottom of a pan cooker etc.During use, pass into alternating current in the heater coil, just produce an alternating magnetic field around the coil, the magnetic line of force of alternating magnetic field is most of by metallic object, produces a large amount of eddy current in metallic object, thereby produces heat.The conventional ceramic vessel do not satisfy the condition that produces eddy current, heat so can not be placed on the electromagnetic oven.Inventing a kind of pottery is transform as can be with the large volumetric apparatus of electromagnetic oven heating, and replacing whole or part substitute beaker can solve jumbo needs, can avoid using again alcolhol burner, has great importance and the practical value of reality.
Summary of the invention
The pottery that the purpose of this invention is to provide a kind of available Electromagnetic Heating of built-in high-frequency electromagnetic signal inductor, this pottery can directly place on the electromagnetic oven and heat.
The technical scheme that adopts for achieving the above object is: a kind of pottery of available Electromagnetic Heating of built-in high-frequency electromagnetic signal inductor, rounded, can add a cover or not add a cover, the pottery that it is characterized in that the available Electromagnetic Heating of described built-in high-frequency electromagnetic signal inductor, embed round iron plate or stainless steel substrates in its bottom embedding formula, form an inner embeding layer, make the pottery bottom form the upper strata, the middle level, lower floor is totally three layers sandwich plank frame, the upper strata of pottery bottom, lower floor is common ceramic material, iron plate or the stainless steel substrates of middle level for embedding.
Described round iron plate or stainless steel substrates, its diameter more than or equal to 10 centimetres, be less than or equal to 85% of pottery base diameter.
Behind high-temperature firing, the two-layer up and down of pottery bottom becomes the body of combining closely with iron plate or stainless steel substrates, the iron plate that its bottom embedding formula embeds or stainless steel substrates are by the upper and lower ceramic material parcel of pottery bottom, and be isolated with extraneous air, has antioxidation.
The operation principle of the pottery of the available Electromagnetic Heating of a kind of built-in high-frequency electromagnetic signal inductor of the present invention is: the high-frequency electromagnetic signal that the inside embeding layer of pottery bottom is used for the inductive electromagnetic stove produces eddy current.Pottery is placed on the electromagnetic oven, electromagnetic oven energising work post consumption electric energy, and generation frequency electromagnetic waves, the iron plate of frequency electromagnetic waves inner embedding at the bottom of bowl or stainless steel substrates produce eddy current (around the electric current of circle circulation), eddy current flow crosses iron plate or stainless steel substrates will consume electric energy, and produces heat.Total conversion process of energy is: electric energy-magnetic field energy-electric energy-heat energy.
The pottery of the available Electromagnetic Heating of the built-in high-frequency electromagnetic signal inductor that employing the inventive method is made, manufacture craft is simple, and cost is low, should not break essence, is convenient to transportation; Pottery is corrosion-resistant, easy cleaning; Can directly place on the electromagnetic oven and heat, through Repeat-heating experiment, reach that 500 potteries are intact not to ftracture; Baoshang cooker etc. in the widely used glass beaker in alternative laboratory, water-bath and the daily life.
Description of drawings
Fig. 1 is the pottery longitudinal sectional drawing of the available Electromagnetic Heating of built-in high-frequency electromagnetic signal inductor.
The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, the 1st, the sidewall of pottery; The 2nd, the upper strata of pottery bottom; The 3rd, the middle level of pottery bottom is made by round iron plate or stainless steel substrates; The 4th, the lower floor of pottery bottom.
When pottery embryo processed, embed iron plate or stainless steel substrates (3) in advance embedding formula of the bottom of vessel, form an inner embeding layer, the lower floor (4) of the upper strata (2) of pottery bottom and ceramic bowl bottom is common ceramic material, makes the ceramic bowl bottom have three layers.The pottery embryo of pottery in upper strata, bottom (2), middle level (3) and the lower floor (4) of ceramic bowl, forms a bowl end of combining closely behind high temperature sintering.
During use, pottery is placed on the electromagnetic oven, can select as required power suitable between 80～1800W, the reactant that needs are heated heats.
