Embodiment
Explanation and embodiment are described further to the utility model below in conjunction with the accompanying drawings.
Embodiment 1
Reference picture 1, a kind of lid, including：Enclosing cover 100；Inner cap 200, is connected on the inside of the enclosing cover；Heating board 300, positionBetween the enclosing cover 100 and the inner cap 200, wherein, heating board 300 is at least partly corresponded to inner cap 200 and contacted with internalLid carries out auxiliary heating；The rib more than at least one circle protruded towards inner cap side is formed on heating board 300, rib is used to be liftedThe heating area of heating board itself.For the heating board for being compared to the plane of prior art, the rib of protrusion is increased entirelyThe entire area of heating board, then the heating area of transmission heat can also be lifted after heating board is heated.
Alternatively, inner cap 200 is removably connected with enclosing cover 100.For example, inner cap 200 can by engaging, being spirally connected, rivetingThe inner side that mode is connected to enclosing cover 100 such as connect.The connected mode of so detachable enclosing cover 100 and inner cap 200 can be easy to lidCleaning.In addition, when enclosing cover 100 or inner cap 200 are damaged, can also be easy to the replacing of enclosing cover 100 and inner cap 200.Enclosing cover 100 is optionalGround is made up of the relatively low material of the thermal conductivity factors such as plastics, when contacting enclosing cover 100 so as to user, will not be led due to enclosing cover 100Heat and be burned.Inner cap 200 is alternatively made up of the higher material of the thermal conductivity factors such as metal, so that inner cap 200 can be byThe heat of heating board 300 is transmitted to the object upper end heated in rice cooker.
Heating board 300 is that towards the spherical crown shape on the inside of enclosing cover, i.e., whole heating board 300 is a part for sphere, the heatingPlate 300 possesses the heating board 300 of certain radian except being likewise supplied with certain radian with existing compared with the heating board of existing planeEnclosing cover match outer, can also increase outside the heating surface area of itself, thus can be by corresponding heat transfer to inner cap, to reachIndirectly heat is carried out to inner cap so that after culinary art terminates, the outer surface of heated inner cap will not produce a large amount of condensed waters, also enter oneStep prevents condensed water from instilling in cooking cavity body.
Further, the rib in the present embodiment is annular rib, and annular rib 400 can be a circle, or twoCircle, three circles, the radius of above-mentioned annular rib from the center of the heating board to the heating board outer peripheral halfFootpath gradually increases, i.e., the radius closer to the outer peripheral annular rib of heating board is more than the annular rib close to heating board center,All annular ribs are surround around a central point to the week side of boss, improve overall symmetry and aesthetics.
Reference picture 2 and Fig. 3, specifically, also extend through on heating board 300 and are provided with thermometer hole 310 and steam tap hole320, form the annular rib of non-closed at thermometer hole and steam the tap hole region, i.e., above-mentioned thermometer hole 310 andThe closed path of annular rib is separated by steam tap hole 320, and reserved thermometer hole 310 is used to place detection member hereinPart, and reserved steam tap hole 320 is used to receive the steam discharged from inner cap 200.
In order to which heating board 300 is fixed on enclosing cover 100, the heating board in the present embodiment is set towards the edge of enclosing cover sideThere are some pinch plates 330, the pinch plate 330 gos deep into described so that the heating board to be fixed in the groove of the enclosing cover formationCover outside, the pinch plate 330 is plumbness when no assembling is using process；After pinch plate 330 is in confined state,At least a part for pinch plate 330 is in bending state.
In addition to more preferably being assembled, the center of heating board is provided through that hole 340 is fixedly mounted, and fastener is through admittedlyDetermine mounting hole 340 to cover so that the heating board is fixed on outside described, fastener is used cooperatively with pinch plate, heating is improvedThe fitting tight degree of plate.
Additionally, heating board is pasted with heat generating components towards the surface of enclosing cover side；Heat generating components be heating wire, heat-generating pipe orPtc heater.The method that fixed ptc heater can use double faced adhesive tape plus masking foil, the surface of whole ptc heater is wholeSurround, and the surface for making it be close to heating board.Pressing plate can also be used to fix or other fixing means, it should be appreciated that a variety ofThe method of fixed ptc heater belongs to protection domain of the present utility model.
When ptc heater adstante febre, when surface temperature is less than Curie temperature, ptc heater is heated with larger power, whenWhen the surface temperature of ptc heater reaches the Curie temperature of setting, power is drastically reduced, therefore uses ptc heater as perseveranceTemperature heating is used can be without carrying out dry combustion method protection, and not only cost is lower, and safer, more compact structure.
Embodiment 2
Reference picture 4, a kind of cooking apparatus, including：Pot 500, the top of the pot has opening；And it is described aboveLid, the lid is used at least cover the opening.Above-mentioned cooking apparatus can be electric pressure pot, electric cooker and saucepan.
Wherein inner cap 200 be opening towards the spherical crown shape on the inside of pot, the inner cap of the spherical crown shape and the heating board of spherical crown shapeRadian is consistent, and is also equipped with some ribs 210 similar with heating board on the surface of inner cap, is easy to both to carry out the biography of heat energyPass.
The direction of the rib and second rib that are arranged on heating board is in the same direction, and the purpose set in the same direction is to be easy to muscleThe assembling of bar and the second rib between the two, the part of rib protrusion is located at the cell body part of second rib formation, this kindAssembling mode, can cause the maximum utilization of the heating area of heating board, i.e., rib as described in Example 1 increases heating boardSelf-heating area, after heating area after increase is brought into close contact with inner cap, the heated enhancing efficiency of inner cap.
In actual use, even if always on, partial condensation water is also had, then set similar with heating boardAfter second annular rib, the annular rib being capable of adsorption condensing water so that inner cap is when perpendicular to cooker body, and condensed water can be slowStay, will not plunk down.
