Description
Technical field
The present invention relates to a kind of Miniature electric rice cooker, is especially a kind of Miniature electric rice cooker of modified node method, with easy to use, avoids a pot deficiency for body infiltration.
Background technology
Chinese Patent Application No. CN200910130641.8 discloses a kind of boiling used on automobile on September 29th, 2010, heat-preservation electric rice cooker, mainly contain pot caping, pot lid, food steamer, pot housing, heat-insulating lamp LED1, cook lamp LED2, insulation temperature controller composition, heat-generating disc directly contacts with pot inner bag, in the middle of heat-generating disc, install Kick type butterfly shaped dual metal sheet temperature controller assembly, assembly is connected with control circuit board.Heat-generating disc described in this structure directly contacts with pot inner bag, is actually pot inner bag and is bearing on heat-generating disc, and when automobile travels on up-and-down road, pot inner bag slightly can be beated on heat-generating disc, causes the heat losses of last point of heat-generating disc; In addition, because temperature controller is arranged on heat-generating disc, pot inner bag is slightly beated and also can be left temperature controller, causes temperature controller response lag.
In order to overcome the problems referred to above, heat-generating disc and temperature controller are bonded in bottom pot inner bag respectively by heat-conductive bonding agent by some enterprises, this kind of structure solved the problem really at the use initial stage, but still have the following disadvantages: (1) in view of heat-generating disc (electric heating body) be directly cement in bottom inner bag, electric cooker Long-Time Service, heat-conductive bonding agent experiences change of expanding with heat and contract with cold for a long time, heat-conductive bonding agent cementitiousness is easily caused to weaken, loose contact bottom heat-generating disc and inner bag, affect the efficiency of heating surface, even because heat-generating disc comes off, the deficiency that electric cooker cannot use; Further, although heat-conductive bonding agent has good heat conductivility, it has certain resistance (being equivalent to intermediate interlayer) all the time, therefore, arranges the heat-conductive bonding agent of this intermediate interlayer, can affect its efficiency of heating surface all the time between bottom heat-generating disc and inner bag; And heat-conductive bonding agent is heated for a long time, easily affect the heat conductivility of heat-conductive bonding agent, cause the efficiency of heating surface constantly to decline, the more electric energy of loss; (2) in view of the solid of heat-conductive bonding agent needs a period of time, therefore, after heat-conductive bonding agent must be waited completely solid, heat-generating disc is completely fixed, and just can proceed subsequent processing, and this has a strong impact on its production efficiency, is especially not suitable for some enterprises that output demand is large.
In view of above-mentioned deficiency, a kind of electric cooker of my design, by advance at inner bag bottom welding screw rod, and by calandria as in a heat-conducting plate, heat-conducting plate again corresponding screw rod is provided with perforate, and screw rod is connected with nut through after perforate, and heat-conducting plate is pressed on bottom inner bag by nut; Meanwhile, also offer screw in screw rod bottom surface, be connected with screw through behind the bottom of a pan with screw, the unification of inner bag, calandria is fixed on the bottom of a pan, thus overcomes above all deficiencies.
But the electric cooker of such scheme, still has the following disadvantages: screw rod is directly welded on inner bag diapire by (1), easily because welding excessively, causing inner bag diapire to damage, even scrapping; Further, inner bag welds with screw rod, its firmness often affects by welding procedure, so technological requirement is higher; (2) inner bag welds with screw rod, means that inner bag is fixedly connected with heater block system, and during use, inner bag can not take out separately, when being especially cleaning, need whole electric cooker to pick up cleaning of making a return journey, both inconvenient, also easily enter the bottom of a pan because of water, affect electric component, and cause damage; Even because user is careless, whole electric cooker is fallen in the water, causes whole electric cooker to scrap.
Summary of the invention
The object of the invention is to the deficiency overcoming the existence of above-mentioned prior art, and provide a kind of simple and reasonable for structure, inner bag can take out separately use, and when avoiding cleaning, pot body easily seeps water and causes damage, and the efficiency of heating surface is high, install easy Miniature electric rice cooker.
The object of the present invention is achieved like this:
