Description
Technical field
The utility model relates to a kind of kitchen utensils, relates in particular to a kind of electric cooker.
Background technology
Existing electric cooker adopts aluminum liner, generally comprises shell, in the described shell stay-warm case is set, and inner bag is set in the stay-warm case, between described stay-warm case and the inner bag heater is set.In existing electric cooker structure, fixed installation heater---the heat-generating disc of cast aluminium structure in the stay-warm case, the upper surface of heat-generating disc is a sphere, and fits with the outer surface of inner bag bottom, and then heat is passed to inner bag, reaches the purpose of food in the heating kettle.
But the electro-heat equipment of existing electric cooker is the cast aluminium structure and is fixed installation, can not with the supporting use of ceramic liner.Ceramic liner influence because of factors such as the duration and degree of heating, materials in the process of firing can produce a certain amount of distortion, make the defective tightness that contacts between inner bag and the electro-heat equipment, and then cause the part dry combustion method phenomenon to occur, even can cause the heater distortion, also reduce simultaneously the thermal efficiency of electric cooker, increased power consumption.In addition, traditional heating aluminium dish heating area is little, and temperature is too concentrated, if being ceramic material, makes inner bag, slow because of the heat-transfer character of pottery itself, at the position that pottery contacts with heater localized hyperthermia will appear like this, tend to cause the explosion of pottery pot courage.Therefore, ceramic liner can not be used for traditional electric cooker.
The utility model content
At the existing problem and shortage of above-mentioned existing electric cooker, the purpose of this utility model provides a kind of electric cooker with liftable heater.
In order to achieve the above object, the utility model adopts following technical scheme:
This electric cooker comprises shell, in the described shell stay-warm case is set, inner bag is set in the stay-warm case, the heater that the cross section is a U-shaped is set between stay-warm case and inner bag, described heater inside is provided with heater, described heater bottom is fixed with screw, the bottom of described stay-warm case is provided with and the corresponding through hole of screw position, described screw passes described through hole, the part of described screw between described heater and described stay-warm case is equipped with spring, the end that described screw is positioned at described stay-warm case outside is provided with nut, and described screw and spring are fixed on described heater in the described stay-warm case, and described heater can be done the oscilaltion activity in stay-warm case.
When described heater is subjected to downward active force, described screw can move down along described through hole, at this moment spring can be compressed, thereby produce the power that described heater is upwards pushed away, the power that upwards pushes away that is subjected to when described heater equals downward power, described heater stops to move down, and when the power that makes progress that is subjected to during greater than downward power, described heater can move up.
For better heat preservation, between above-mentioned heater and the described stay-warm case heat shield is set, described heat shield is fixed on the described screw, and the described outer spring of screw that is placed on is between described heat shield and described stay-warm case.Described heat shield can move up and down together along with described heater.
Above-mentioned heater is arranged on described heater bottom, and described heater is the heating combining structure that nickel filament and mica sheet are formed.
Better for effect of heat insulation, described heat shield is circular.
Above-mentioned heater is made of aluminum usually, the thermal conductivity factor height; Above-mentioned stay-warm case is fabricated from iron usually.
Above-mentioned inner bag is generally the ceramic-like inner bag.
Owing to adopted technique scheme, compare with existing electric cooker, screw and the spring between heater and stay-warm case that the stay-warm case bottom through-hole is passed in electric cooker utilization described in the utility model support heater, heater is suspended in the stay-warm case, because the existence of screw and spring, heater is liftable heater.During use, heater can descend under the pressure effect of pottery pot courage, at this moment spring is compressed, produce power upwards, because the support force that has spring to make progress, the ceramic liner bottom fits together with heater, sealing effectiveness is better, prevent the consumption of heat effectively, thereby improve the thermal efficiency, energy savings.
Description of drawings
Fig. 1 is an electric cooker structural representation described in the utility model.
The specific embodiment
In order the utility model to be described better,, further specify technical characterictic of the present utility model and function characteristics below in conjunction with specific embodiment.
As shown in Figure 1, electric cooker described in the utility model comprises shell 1, stay-warm case 2 is set in the described shell, ceramic liner is set in the stay-warm case, it is the heater 3 and the heat shield 5 of U-shaped that the cross section is set between stay-warm case and ceramic liner, the heater 3 inner heaters 4 that are combined into by mica sheet and nickel filament that are provided with, described heater bottom is fixed with screw 6, the bottom of described stay-warm case is provided with and the corresponding through hole of screw position, the other end of screw 6 passes the through hole of described stay-warm case 2 bottoms, screw 6 is positioned at the outer end of stay-warm case and is provided with nut, and the part of screw 6 between heat shield and stay-warm case is provided with sleeve pipe 7, and sleeve pipe 7 is outside equipped with spring 8.
For avoiding the influence of high temperature, between stay-warm case 2 and heater 3, heat shield 5 is set to electric elements.This heat insulation iron plate is circular, is parastate and is installed between stay-warm case 2 and the heater 3, its role is to reduce the temperature of stay-warm case bottom, for the stay-warm case bottom electric control element is installed proper temperature environment is provided.Thereby prevent that effectively the electronic devices and components that install the stay-warm case bottom from destroying because of being subjected to temperatures involved, thereby prolong the service life of product.
Adopt the electric cooker of this design can use ceramic liner, be particularly useful for boccaro class ceramic electric cooker inner bag.
During use, heater descends under the pressure effect of pottery pot courage, and described screw moves down along described through hole, screw stretches out through hole and is exposed at the outer part increase of stay-warm case, at this moment, spring is compressed, thereby produces power upwards, because the support force that has spring to make progress, the ceramic liner bottom fits together with heater, and sealing effectiveness is better, prevents the consumption of heat effectively, thereby the raising thermal efficiency, energy savings.
The above-mentioned specific embodiment is illustrated the utility model with preferred embodiment, but the example of this visualization of just lifting for the ease of understanding should not be considered to be the restriction to the utility model scope.Equally, according to the description of the technical solution of the utility model and preferred embodiment thereof, can make various possible being equal to and change or replacement, and all these changes or replacement all should belong to the protection domain of the utility model claim.
