Description

Technology Field

[0001] The present invention involves developing a heating container made of glass suitable for use on an induction range and a temperature control device. By setting the cooking temperature to be appropriate for the cooking of the food ingredients when performing various cooking tasks such as brewing tea, decoction of medicinal herbs, making Sikhye, making Cheonggukjang, or boiling porridge, the invention prevents overheating and minimizes the margin of error of the set temperature. More specifically, the invention involves forming a glass container with different thicknesses for the bottom and the main wall, forming a magnetic conductive film on the bottom surface, and forming a retaining ledge on the main wall to accommodate an internal strainer. Additionally, a hole is drilled in the top plate of the induction range and a temperature sensor is installed in the hole. By allowing the temperature sensor to move up and down on the top plate, when the heating container is placed on the top plate, the temperature sensor contacts the bottom of the container and descends from the top plate to accurately detect the temperature of the food being heated in the container. Consequently, the temperature sensor is suitable for the type of food. It is configured so that the heating temperature is accurately selected to ensure proper cooking. Background Technology

[0003] An induction range is configured such that a coil is installed on the top plate where a cooking vessel is placed, and when current flows through the coil, an alternating magnetic field is formed, and this alternating magnetic field is concentrated toward the vessel with high projection, forming eddy currents in the vessel, and heat is generated due to the resistance of the eddy currents and the object being heated, thereby heating the food.

[0004] Therefore, the bowl is configured to have a magnetic resistance component, and when current is sent to the coil, a high-frequency magnetic field is generated in the coil. When the magnetic field passes through the bottom of the bowl placed on the stovetop, eddy currents are generated by the resistance component contained in the material of the bowl. The eddy currents generated at the bottom of the bowl heat up only the bowl itself, so induction heating occurs in which only the bowl becomes hot without the stovetop heating up. Consequently, the thermal efficiency is high, the heating time is short, making cooking time and electricity usage efficient. There is no risk of burns or fire to the person cooking, the stovetop remains clean, and there is no emission of harmful substances, which has the advantage of being beneficial to health.

[0005] However, since the temperature setting device is located far from the container and the sensor is indirect, there is a large margin of error, making temperature control imprecise and reducing the accuracy of cooking and heating, which results in the inconvenience of not being able to cook at the appropriate temperature for the food. The problem to be solved

[0011] A heat-resistant support member (5), which is an insulating plastic molded product, is formed such that a hole (1b) is formed through the upper and lower center of the top plate (1a) on which a glass container is placed on the top plate of the induction range, an attachment flange (5a) is formed on the outer periphery of the upper part by being molded with a heat-resistant resin on the inside of the hole, the attachment flange is attached to the inner surface of the top plate with a heat-resistant waterproof adhesive (5b), a through hole (5c) is formed in the center, and a coupling groove (5e) is formed on the inner surface of the main wall (5d) formed at the bottom of the through hole.

[0012] A bottom plate (6b) is formed on the lower part of the main wall (6a) by molding with silicone rubber, and a connecting part (6a') is formed on the lower part of the main wall and connected to the connecting groove (5e) of the heat-resistant support part (5).

[0013] A silicone rubber support (6) having a hemispherical connecting portion (6c) formed from the main wall (6a) to the center, through holes (6d) (6e) formed from the center of the hemispherical connecting portion to the bottom center, an annular expansion portion (6f) formed on the outer circumference of the upper through hole (6d), and a coupling groove (6g) formed on the upper surface with an open top.

[0014] The structure is formed as a cylindrical body (7a) that is formed from an alloy mainly composed of aluminum and iron components and is inserted into a hole (1b) of a top plate (1a), the upper surface of the cylindrical body is formed as a flat surface (7b), an annular locking part (7c) is formed on the outer circumference of the middle part of the cylindrical body, and a connecting tube (7d) with a reduced diameter is formed on the bottom surface of the annular locking part, which is inserted and fixed into the upper through hole (6d) of a silicone rubber support, the lower end of the connecting tube contacts the bottom of the silicone rubber support, and a storage part (7e) that opens downward is formed inside the cylindrical body, and a temperature sensor (7f) is stored inside, with a wire (7f') exposed to the lower half and connected to a control IC, so that the upper half of the temperature sensor protrudes a certain height above the hole (1b) of the top plate (1a) and sinks into the inside of the top plate when a glass container is loaded. Effects of the invention

[0016] The present invention, as described above, selects a glass container for the heating vessel, having a bottom thickness of 4 mm and a main wall thickness of 3 mm. Since the bottom plate and the main wall are manufactured separately and fused, a glass container with selectable bottom thickness can be produced. A magnetic conductive film is formed on the bottom surface of the glass container, allowing the magnetic field formed in the coil of an induction range to project and generate eddy currents. Since several inward protrusions are formed at a certain height on the main wall of the glass container, when a filter container is inserted into the glass container, an annular support formed on the outer periphery of the upper part of the filter container is supported, thereby enabling the filter container to be installed inside the glass container. Consequently, food to be heated can be placed in the mesh container and water poured in to heat it. When the material to be heated is placed in the glass container, a lid is attached, and the container is placed on the top surface of an induction range, the temperature sensor formed on the top surface of the induction range is pressed down by the weight of the glass container and descends below the top surface, causing the bottom surface of the glass container to come into contact with the top surface. Consequently, electricity is supplied to the coil and the heating temperature is set. When heating occurs, current flows through the coil, generating an alternating magnetic field. As this alternating magnetic field passes through the bottom of the glass container, eddy currents are generated by the resistive components contained in the magnetic conductive film, causing the glass container to heat up and resulting in induction heating where only the glass container becomes hot. Since the temperature sensor is always in contact with the bottom of the glass container and detects the heat of the container, transmitting this information to the control IC, the heating temperature of the glass container is accurately detected in real time. Once the set temperature is reached, heating is controlled according to the control system. This ensures that the object being heated inside the glass container is heated within the set temperature range, preventing overheating. Consequently, the advantage of being able to cook at an appropriate temperature suitable for cooking can be obtained.

[0017] Since the temperature sensor is in close contact with the magnetic conductive film formed on the bottom of the glass container placed on the induction cooktop, accurate temperature detection is possible, and since the temperature sensor is supported by the silicone rubber support of the heat-resistant support and moves up and down, the advantages of convenient installation and guaranteed durability can be obtained.

[0018] In addition, the glass container of the present invention is formed with a bottom thickness of 4mm, which is thicker than the main wall thickness, so it has the advantage of not easily rupturing even when heated repeatedly. Brief explanation of the drawing
