Description
Technical field
The utility model relates to the electric cooker technical field, particularly a kind of direct temp sensing type electric cooker.
Background technology
Chinese patent application number: CN201210043787.0 disclosed a kind of micro electric pot for cooking rice on July 4th, 2012, comprise shell, inner bag and loam cake thereof, the inner bag setting in the enclosure, it is characterized in that, it also includes heat-conducting plate, electrothermal tube and thermal insulation layer, thermal insulation layer can be the heat conducting film of insulation, compress the chamber and be provided with on the heat-conducting plate, described thermal insulation layer wraps electrothermal tube, they are pressed in the compression chamber of heat-conducting plate together, be provided with thermal conductive surface on the heat-conducting plate, thermal conductive surface cements in the inner bag bottom by heat-conducting glue.Described inner bag bottom also is connected with temperature controller, to prevent inner bag bottom dry combustion method, and heating-up temperature that also can the Real-Time Monitoring inner bag.But because temperature controller cements in the outer bottom of inner bag by heat-conductive bonding agent, the fixed installation mode of this temperature controller, have the following disadvantages: (1) directly cements in the outer bottom of inner bag in view of temperature controller system, electric cooker uses for a long time, and heat-conductive bonding agent experiences the variation of expanding with heat and contract with cold for a long time, causes easily the heat-conductive bonding agent cementitiousness to weaken, temperature controller and the loose contact of inner bag outer bottom, cause Temperature-control Monitoring inaccurate, even because temperature controller comes off, the deficiency that electric cooker can't use; Have, although heat-conductive bonding agent has good heat conductivility, it has certain thermal resistance (being equivalent to intermediate interlayer) all the time again, therefore, temperature controller can't directly be monitored the temperature of inner bag outer bottom, and there is some difference all the time even delay in its temperature control, causes electric energy loss; And heat-conductive bonding agent is heated for a long time, affects easily the heat conductivility of heat-conductive bonding agent, causes temperature controller monitoring inner bag temperature inaccurate; (2) need a period of time in view of the solid of heat-conductive bonding agent, therefore, after necessary heat-conductive bonding agent such as grade is fully solid, temperature controller is completely fixed, just can proceed subsequent processing, this has a strong impact on its production efficiency; (3) because temperature controller is automatically reset, when the inner bag excess Temperature, so that after the temperature controller take-off, after needing the inner bag temperature to decline to a great extent, temperature controller just can reset, when cooking, when the water of inner bag is reduced to when a certain amount of, the inner bag temperature raises, the temperature controller take-off, until after declining to a great extent, temperature controller just can reset, therefore, electric cooker can not can not then boil other a pot of cooked rice again after having boiled a pot of cooked rice, must with electric cooker after cool after a while, temperature controller be resetted just can reuse, for the user increases unnecessary trouble.
The utility model content
The purpose of this utility model is to overcome the deficiency that above-mentioned prior art exists, and provides a kind of simple and reasonable for structure, installs and operate simple and easy, the direct temperature-sensitive of inner bag diapire quilt, the energy-saving electric cooker of the accuracy of Effective Raise temperature-sensitive and monitoring.
The purpose of this utility model is to realize like this.
Direct temp sensing type electric cooker, comprise inner bag and electric heating body, electric heating body is fixed on the inner bag diapire by screw assembly and is close to the inner bag diapire, it is characterized in that, also include heat transfer plate, heat transfer plate comprises and interconnects transverse slat and the side plate that is integral, consist of certain angle between transverse slat and the side plate, transverse slat is fixed on the inner bag diapire by described screw assembly and is close to the inner bag diapire, is fixed with overheat protector on the side plate, and overheat protector and electric heating body are electrically connected; This kind of electric cooker, because heat transfer plate system directly is close to the inner bag diapire, and overheat protector passes through heat transfer plate, directly temperature-sensitive and monitoring inner bag diapire temperature, consist of direct temp sensing type, both effectively improve the accuracy of temperature-sensitive and monitoring, can save electric energy again, and protected simultaneously components and parts because of the overheated infringement that causes; Have, because heat transfer plate has good thermal conductivity, and by being bent into certain angle, that is: transverse slat and side plate are installed in overheat protector on the side plate again, and both convenient the installation was convenient to again regulate (such as " manual operation ") overheat protector; More have plenty of, overheat protector is fixed on the heat transfer plate, because the non-inner bag diapire of heat transfer plate, therefore, overheat protector can be securely fixed on the heat transfer plate by perforate or welding manner, avoids bonding because of the use adhesive, and causes the deficiency that comes off easily.
