Patent application number | Description | Published |
20080217323 | HEATING DEVICE - A heating device having an improved heat resistance structure is provided. The heating device may include a heating element that generates heat, and an elastic conductive part that applies electricity to the heating element. A connector may be provided between the elastic conductive part and the heating element to preclude direct contact between the heating element and the elastic conductive part. The heating element may be fixed to one side of the connector, and the elastic conductive part may be fixed to the other side of the connector to allow current applied from the elastic conductive part to flow to the heating element. | 09-11-2008 |
20090230122 | HEATER HOLDER AND ELECTRIC HOB INCLUDING THE SAME - Provided are a heater holder and an electric hob including the heater holder. Both end portions of a tube heater are supported by the heater holder having predetermined elasticity. Therefore, food can be cooked more rapidly, and the tube heater can be easily installed. Furthermore, damages caused by heat generated from the tube heater can be minimized. | 09-17-2009 |
20090242547 | COOKER AND METHOD FOR CONTROLLING THE SAME - A cooker and a method for controlling the cooker are provided. The cooker may include a heating source configured to generate heat, a detection sensor configured to detect a temperature of the heating source, and a controller configured to compare a current temperature of the heating source detected by the detection sensor with at least one control reference temperature so as to control an on/off operation of the heating source. Until the current temperature of the heating source reaches the control reference temperature, the controller controls the heating source to be kept in an on-state, and when the current temperature of the heating source exceeds the control reference temperature, the controller controls the heating source to be repeatedly turned on and off for a predetermined period of time or a predetermined number of times. | 10-01-2009 |
20100018961 | COOKING APPARATUS - Provided are a cooking apparatus and a method for controlling the same. The cooking apparatus senses the size of a cooking vessel, or more specifically, the undersurface area of the cooking vessel, and selectively operates heaters accordingly. Therefore, food can be more efficiently cooked. | 01-28-2010 |
20100044367 | INDUCTION HEATING DEVICE - An induction heating device includes a main body, an induction coil provided in the main body and forming an electromagnetic field, and an induction coil driving circuit unit positioned in the main body to be physically and thermally separated from the induction coil. | 02-25-2010 |
20100193502 | ELECTRIC HEATER - Disclosed is the electric heater including a base, and a heating unit having a plurality of unit heating elements disposed on a plate surface of the base and at least one of heating connection portions configured to heat and conductively connecting the unit heating elements to each other and non-heating connection portions configured not to heat and conductively connecting the unit heating elements to each other, thereby preventing a thermal stress concentration, thus to prevent damage to the heating unit and to enhance its output. | 08-05-2010 |
20110017721 | Filament Supporter and Tube Heater, Electric Hob Having the Same - The present invention relates to a filament supporter and a tube heater having the same. In the present invention, the contact between a tube and a filament is prevented by the filament supporter. Accordingly, according to the present invention, there is an advantage in that the filament is efficiently prevented from being contacted to the tube. | 01-27-2011 |
20110017722 | Heater Supporter and Electric Hob Including the Same - Provided are a heater supporter and an electric hob including the heater supporter. A tube heater is supported by the heater supporter, and at least a portion of the heater supporter is formed of a ceramic containing material. Therefore, food can be cooked more rapidly, and the tube heater can be easily installed. Furthermore, damages caused by heat generated from the tube heater can be minimized. | 01-27-2011 |
20120103971 | COOKING APPLIANCE AND A CONTROL METHOD THEREOF - Provided are a cooking appliance and a control method thereof. A cooking appliance according to an embodiment of the present invention comprises a top plate on which a cooking container is placed, a plurality of winding parts including a plurality of coils horizontally arranged under the top plate, a plurality of relay parts including a plurality of relays that each connected to the plurality of coils, and an inverter part for applying a voltage of high frequency to the plurality of winding parts. | 05-03-2012 |
20120132645 | INDUCTION HEATER - The present invention comprises a grill unit which is heated by induction current. The grill unit comprises a grill which is heated by induction current, and a supporting unit is placed below the grill to store foreign matter falling from the grill. In addition, the grill unit is fixed to a heater main body by being coupled. The supporting unit comprises a coupling unit which is formed to be coupled with the heater main body. Additionally, the heater main body comprises a seat portion at one side, which is coupled to the coupling unit. | 05-31-2012 |
