Abstract

The utility model relates to an electric heating apparatus of a period-heat cooking container. The electric heating apparatus of a period-heat cooking container is composed of a heat generation disc, an electrothermal tube (wire), a bimetallic thermostat which can be adjusted, a base, etc. The heat generation disc forms a cuboid shape, or a cylinder shape, or an inverse conical bench shape. The shape of the heat generation disc can be the same as the shapes of other cooking containers. The utility model has the advantages of simple structure and long service life. The heating surface of a cooking container is large and homogeneous, and can be separated. The electric heating apparatus of a period-heat cooking container is suitable for the electrical heating for a pot, a cup, a rice box, etc.

Description

Electric heating apparatus of period-heat cooking container

The utility model belongs to the heater of cooking utensil, relates to a kind of electric heater unit of all hot type cooking-vessels, is applicable to the electric heating of cooking-vessels such as pot, cup, lunch box.

Existing electrically heated cooking utensil generally is to connect one in the bottom of cooking-vessel (as pot body, cup, box body etc.) to be contained in the heating wire (pipe) under the heat-generating disc by heat-generating disc, the heater that base etc. constitute.Because heat-generating disc only contact with cooking-vessel bottom, the cooking-vessel inequality of being heated, food easily turns to be yellow and burns in the container; Heat-generating disc power is big, and volume is little, and when heat-generating disc and container bottom loose contact, heat passes less than container, and heat-generating disc usually burns because of overheated; The cooking utensil that cooking-vessel and electric heater unit are fixedly connected, the cleaning of container is used inconvenient, is prone to phenomenons such as electric leakage.

The purpose of the utility model is intended to overcome above-mentioned the deficiencies in the prior art, provides that a kind of electric heater unit and cooking-vessel are separable, the cooking-vessel heating surface is big and the electric heater unit of uniform all hot type cooking-vessels.

Technical solution of the present utility model is a kind of electric heater unit of all hot type cooking-vessels, the heat-generating disc that electric heating pipe box or groove are arranged by the bottom, being arranged in electric heating pipe box or groove and two ends has the electrothermal tube of power connection (silk), the base that connects with heat-generating disc constitutes, and its feature part is that the inner surface configuration of heat-generating disc 1 is a spill.

Can also be in series with a scalable bimetal temperature control device 5 on the electrothermal tube in the utility model technical solution (silk) 3, a projection 6 is arranged at heat-generating disc 1 bottom, and the sampling end of scalable bimetal temperature control device 5 (thermometric end) contacts or socket with projection 6.

Spill heat-generating disc 1 described in the utility model technical solution is cylinder, rounding stage body or other pots bodily form, the cup shape of upper end open.

Spill heat-generating disc 1 described in the utility model technical solution can also be cuboid, square or other lunch box body shape of upper end open.

Compared with prior art, the utlity model has following characteristics:

(1) adopt the spill heat-generating disc, the overall dimension of heat-generating disc and cooking-vessel (pot body, cup, box body etc.) matches, and contact-making surface is big, and heat-conducting efficiency improves greatly, and cooking-vessel has a narrow range of temperature everywhere, is heated evenly, and the difficult jaundice of food is burnt in the container;

(2) use scalable bimetal leaf temperature controller, heating-up temperature is adjustable, and this thermostat contacts with projection heat-generating disc under, and the accurate also scalable of temperature control can not damaged heat-generating disc because of overheated, improves the useful life of heat-generating disc greatly;

(3) because heat-transfer area is big, temperature is adjustable, make the empty burning-tolerant of cooking-vessel, also can be used for the baking of food, make the not only available aluminium of material of making cooking-vessel, materials such as available stainless steel, devitrified glass, boccaro also;

(4) cooking-vessel and heater are separable, the use of container, more convenient, the safety of cleaning.

Fig. 1 is the utility model embodiment 1 sectional structure schematic diagram;

Fig. 2 is the utility model embodiment 2 sectional structure schematic diagrames;

Fig. 3 is the utility model embodiment 3 sectional structure schematic diagrames.

Among the figure: 1-heat-generating disc, 2-electric heating pipe box or groove, 3-electrothermal tube (silk), 4-base, 5-scalable bimetal temperature control device, 6-projection, 7-pot cover, 9-screw, 10-cup, 11-box body, 12-lid, 8-pot body.

Below by embodiment the utility model is further described:

Embodiment 1: referring to Fig. 1.A kind of all hot type electricity chafing dish are made up of aluminum pot and electric heater unit.Aluminum pot is made of pot cover 7 and reverse frustoconic pot body 8; Electric heater unit is by the reverse frustoconic heat-generating disc 1 that can match with pot body 8, the electric heating pipe box (or groove) 2 of heat-generating disc 1 bottom, there is the electrothermal tube 3 of power connection at the two ends that are positioned at electric heating pipe box 2, is fixed on the bakelite base 4 of heat-generating disc 1 bottom with screw 9, the scalable bimetal temperature control device 5(that is supported on base 4 sidewalls is with commercially available consistent) etc. formation, one projection 6 is arranged at heat-generating disc 1 bottom, the sampling end of scalable bimetal temperature control device 5 and projection 6 sockets (or contact).

During use, will add thermal material and put into pot body 8, and cover pot cover 7, energized can heat, because a heat-generating disc 1 and pot body 8 shapes are coincide, pot body 8 heating surfaces are big and even.Regulate bimetal temperature control device 5 may command heating-up temperatures.

Embodiment 2: referring to Fig. 2.A kind of week hot electric cup, comprise cylindrical aluminium cup 10 and electric heater unit, heat-generating disc 1 inner surface configuration of electric heater unit is consistent with cup 10 shapes to be cylindrical, both can overlap and merge good contact, other structures are equal to embodiment 1, slightly.

Embodiment 3: referring to Fig. 3.A kind of week thermoelectric lunch box, form by lunch box and electric heater unit.Lunch box is made of rectangle stainless steel box body 11 and lid; The inner surface configuration of the heat-generating disc 1 of electric heater unit is the rectangular shape that can coincide with box body 11, the base 4 built-in heat-preservation cotton that are placed with, and other are with embodiment 1, slightly.

The utility model is not limited to the foregoing description, and the utility model content is described all can be implemented.
