[0002] With the improvement of modern life quality and people's pursuit of healthy life, traditional household appliances are facing an urgent need for transformation and upgrading. Because cooking utensils made of metal or plastic release harmful substances during the heating process, affecting the quality of food and bringing health and safety risks, ceramic utensils are gradually being valued by the public. However, there are the following problems in the current application of ceramic utensils in household appliances: 1. Ceramic appliances heated by electric heating tubes have low heating temperatures and slow speeds, and poor user experience. 2. The heating temperature speed of ceramic appliances heated by electric ceramic stoves has improved, but users need to manually control it based on their operating experience, which limits most users. 3. There is a contradiction between temperature and control in the heating method of electric ceramic stoves. The high temperature platform poses a hidden danger to the safety of ordinary ceramic utensils, and the price of ceramics that can withstand high temperatures is very expensive, which limits the development of the market. The present invention uses electromagnetic heating in conjunction with the use of ceramic utensils to achieve the characteristics of health, safety, and convenience. Summary of the invention

[0003] The present invention provides a multifunctional ceramic cooking component and a control method thereof to solve the problems in the above-mentioned background technology.

The ceramic utensil is placed on the induction cooker, and the induction cooker is connected to a household power supply to provide heat for the food in the ceramic utensil for cooking. A heat insulation board is added to the traditional induction cooker, and the heat insulation board is installed between the microcrystalline board and the coil to isolate the coil and the power board from the heat transferred downward from the cooking utensil to prevent the coil or the power board from being damaged due to overheating. A magnetic conductive layer is sprayed on the bottom of the ceramic utensil, and a protective layer is laid on the bottom of the magnetic conductive layer.

DETAILED DESCRIPTION

[0013] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0014] See also Figure 1-Figure 7 The multifunctional ceramic cooking assembly shown includes an induction cooker 1 and a ceramic utensil. The ceramic utensil is placed on the induction cooker 1. The induction cooker 1 is connected to a household power source to provide heat for the food in the ceramic utensil for cooking.

[0015] The induction cooker 1 includes a microcrystalline board 11, a heat insulation board 12, a surface shell 13, a temperature sensor 14, a coil 15, a control board 16, a power board 17, a fan 18 and a bottom shell 19. The temperature sensor 14 is installed in contact with the microcrystalline board 11. The coil 15, the control board 16, the power board 17 and the fan 18 are all installed between the surface shell 13 and the bottom shell 19. The microcrystalline board 11 is provided above the surface shell 13. The microcrystalline board 11 is usually bonded to the surface shell 13. The above structure is a common structure of a traditional induction cooker. The induction cooker 1 of this embodiment is provided with a heat insulation board 12 on the basis of a traditional induction cooker. The heat insulation board 12 is installed between the microcrystalline board 11 and the coil 15. The specific installation position of the heat insulation board 12 is on the top surface of the surface shell 13 or below the bottom surface of the surface shell 13, and is used to isolate the coil 15 and the power board 17 from the heat transmitted downward from the cooking utensils to prevent the coil 15 or the power board 17 from being damaged due to overheating.

[0016] Traditional induction cookers are only suitable for metal and other utensils that have magnetic conductivity. The maximum temperature of metal utensils during cooking is generally around 200°C. The heat conducted downward by the cooking utensils will not usually damage the coils in the induction cooker. The induction cooker of the present invention is matched with ceramic utensils. Since the thermal conductivity of the ceramic material itself is slightly lower than that of metal, the temperature of the ceramic utensils during cooking can reach more than 400°C. Such a high temperature is transmitted downward to the inside of the induction cooker, which will have a serious impact on its coils or power boards, and even cause overheating and damage to the coils or power boards. Under the overall technical solution of the present invention, it is possible for an induction cooker to heat and cook ceramic utensils.

[0017] The specific forms of ceramic utensils can be varied according to needs, including Chinese medicine cooking pots, soup pots, frying pans, tea sets and other ceramic utensils. A magnetic conductive layer is sprayed on the bottom of the ceramic utensils. The magnetic conductive layer is used to solve the problem that the ceramic material is not magnetic and cannot be used for induction cooker heating. A protective layer is laid on the bottom of the magnetic conductive layer to effectively ensure that the thermal expansion coefficient of the entire ceramic utensil is consistent, so that the problem of inconsistent thermal expansion coefficients between the ceramic utensil body and the magnetic conductive layer is effectively controlled, avoiding damage to the ceramic utensil body or even rupture due to inconsistent thermal expansion coefficients. Example

[0018] See also Figure 2 The surface shell 13 of the induction cooker 1 has a mounting groove 131 , and the heat insulation board 12 is placed on the mounting groove 131 and covered on the surface shell 13 through the microcrystalline board 11 above it. Example

[0019] See also Figure 1-Figure 3 A ceramic medicine pot 2 for cooking Chinese medicine is matched on the induction cooker 1. The medicine pot 2 includes a pot body 21 and a pot cover 22. The pot cover 22 covers the top of the pot body 21. The bottom of the pot bottom 211 of the pot body 21 is sprayed with a magnetic conductive layer 212, and the bottom of the magnetic conductive layer 212 is laid with a protective layer 213. Example

[0020] See also Figure 2 , 4 5. A ceramic soup pot 3 for cooking soup is matched on the induction cooker 1. The soup pot 3 includes a pot body 31 and a pot cover 32. The pot cover 32 covers the pot body 31. The bottom of the pot bottom 311 of the pot body 31 is sprayed with a magnetic conductive layer 312, and the bottom of the magnetic conductive layer 312 is laid with a protective layer 313. Example

[0021] See also Figure 2 , 6 7. A ceramic frying pan 4 is matched on the induction cooker 1. A magnetic conductive layer 42 is sprayed on the bottom of the pan bottom 41 of the frying pan 4, and a protective layer 43 is laid on the bottom of the magnetic conductive layer 42. Example

[0022] In order to achieve the above technical effects and ensure that the ceramic ware can withstand the high temperature generated by the above technical solution, the clay raw material is selected to have a heat resistance of more than 500°C.

[0023] The control method of the multifunctional ceramic cooking component provided by the present invention is: for an induction cooker with an effective power value greater than 1000W, first heat it at 1 / 4 of the effective power for 5 seconds, then increase it to 1 / 2 of the effective power, keep it for 10 seconds, then increase it to 3 / 4 of the effective power, and then keep it for 15 seconds before increasing it to the highest effective value; for an induction cooker with an effective power value less than or equal to 1000W, first heat it at 1 / 4 of the effective power for 2-3 seconds, then increase it to 1 / 2 of the effective power, keep it for 12-13 seconds, and then increase it to the highest effective value of the effective power.

[0024] The control method provides a necessary buffer stage for the cooking utensil made of ceramic material, during which the heating power is gradually increased to alleviate the relative force of the ceramic utensil against the thermal expansion of the magnetically conductive layer, thereby ensuring the service life and safety of the ceramic utensil.
