Abstract

The utility model relates to an external electric heating water kettle with a corrugated bottom. The utility model is composed of a kettle cover, a handle, a kettle body, a heating disc, an electric heating pipe, a thermostat, a base, etc. The bottom of the kettle body and the heating disc are provided with grooves which are meshed. The contact area is large. The heat efficiency is high. When the water temperature of the kettle body achieves a certain valve, the thermostat automatically cuts off the power supply. The energy is saved.

Description

External heating electric kettle with corrugated bottom

The utility model relates to a kind of utensil to boil water, outer thermoelectric kettle at the bottom of particularly a kind of corrugated.

Existing water cooking appliance is commonly used kettle and insulating pot, and the former is made of kettle body, pot lid and handle, and the latter ties up in the former the kettle body electrothermal tube is set; When the former uses, the kettle body bottom that fills water placed on the cooking stove heat, because kettle body bottom is plane, heating surface area is little, and the thermal efficiency is low, and the time of heating up water is longer; The latter's electrothermal tube uses the easy scaliness in rear surface, electrothermal tube easy burn-out (during particularly empty the burning), and service life is shorter.

The purpose of the utility model is intended to overcome above-mentioned deficiency of the prior art, and outer thermoelectric kettle at the bottom of the big corrugated of a kind of heating surface area is provided.

Technical solution of the present utility model is: outer thermoelectric kettle at the bottom of a kind of corrugated, and by the kettle body that water draining beak is arranged, pot lid, two ends are connected in the handle on the kettle body.Electric heater unit is formed, and its feature part is:

There is equally distributed annular groove (4) bottom surface of described kettle body (1);

Described electric heater unit is evenly distributed with the heat-generating disc (5) that annular groove (6), bottom surface have electric heating pipe box or groove (7) by top, being arranged in electric heating pipe box or groove (7) and two ends has the electrothermal tube (silk) (8) of power connection, the base (10) that is fixedly connected with kettle body (1) constitutes, groove (4) and groove (6) are meshing with each other, electric heating pipe box or groove (7) be positioned at part groove (6) under.

In the utility model technical solution, can also be connected in series (unadjustable) bimetal temperature control device (11) on the described electrothermal tube (silk) (8), this bimetal temperature control device (11) is connected in the position that heat-generating disc (5) bottom center does not have groove (7), promptly do not contact the position of electrothermal tube (silk) (8), make thermostat (11) and water temperature approaching.

In the utility model technical solution, one can also be connected in series on the described electrothermal tube (silk) (8) and bimetal temperature control device (12) can be regulated, this can be regulated bimetal temperature control device (12) and be fixedly connected on base (10), and its sampling end contacts with heat-generating disc (5) or connects.Thermostat (11) and (12) can be used separately.

In the utility model technical solution, the base (10) of described heat-generating disc (5) below can be built-in with adiabator layer (13), to reduce thermal loss.

The utlity model has following characteristics:

(1) kettle body bottom surface and heat-generating disc adopt intermeshing groove, and contact area is big, and kettle body heating surface area is big, the heat utilization efficiency height, and water temperature rises rapidly;

(2) be provided with from electrothermal tube (silk) position bimetal temperature control device 11 far away, make this thermostat and water-in-kettle temperature approaching, temperature control is more accurate; Setting can be regulated bimetal temperature control device 12, and the hot water that needs temperature can be provided; And can avoid the empty burning of electric heating, electrothermal tube (silk) long service life;

(3) simple in structure, cheap, thermal efficiency height, energy-conservation obvious.

Fig. 1 is the utility model example structure schematic diagram;

Fig. 2 is kettle body 1 a bottom structure schematic diagram among Fig. 1;

Fig. 3 is heat-generating disc 5 structural representations that are equipped with electrothermal tube among Fig. 1;

Fig. 4 is the A-A cutaway view of Fig. 3.

Among the figure: 1-kettle body, the 2-pot lid, the 3-handle, the 4-groove, the 5-heat-generating disc, the 6-groove, the 7-groove, the 8-electrothermal tube, the little electrothermal tube of 9-, the 10-base, the 11-bimetal temperature control device, 12-can regulate bimetal temperature control device, the 13-adiabator layer.

Be an embodiment of the present utility model below:

Outer thermoelectric kettle at the bottom of a kind of corrugated, comprise: pot lid 2, there are water draining beak and bottom surface that the kettle body 1 of the toroidal cavity 4 at 2 intervals is arranged, be positioned at kettle body 1 below, have and groove 4 intermeshing grooves 6, heat-generating disc 5 with groove 6 position corresponding groove 7 is arranged at the bottom, place groove 7 two ends to be associated with the electrothermal tube 8 and the little electrothermal tube 9 of the serial connection of power connection, be connected in heat-generating disc 5 center bottom and be serially connected in unadjustable bimetal temperature control device 11 on the electrothermal tube, the base 10 that is fixedly connected with kettle body 1, be connected on the base 10, the sampling end contacts with heat-generating disc 5, be serially connected in the bimetal temperature control device regulated on the electrothermal tube, place the warming plate 13 in the heat-generating disc 5 below bases 10.

During use, inject water in the kettle body 1, power connection that connects with electrothermal tube and power supply UNICOM, the electrothermal tube heating is risen water temperature, when water temperature rose to a certain temperature of setting, unadjustable bimetal temperature control device 11 maybe can be regulated bimetal temperature control device 12 and can cut off the electricity supply automatically, stopped heating, when water temperature is reduced to certain value, can connect power supply automatically again.

The utility model is not limited to this embodiment, and the utility model content all can be implemented.
