CN2395651Y - Multifunctional cast-iron electric heating pot - Google Patents

Abstract

The utility model discloses a multifunctional cast-iron electric heating pot, mainly composed of a pot body, a casing connected to the bottom of the pot body and an electronic heat control device. The utility model has the improvement that the circumference of a heating element 5 connected to the bottom of the pot body 3 through welding points is filled and wrapped with a sealed heat conduction layer 6; because the heating element 5 is always and firmly attached on the bottom of the pot body 3 tightly by the welding points, the phenomena that the original connecting piece is heated to expansion and deformation to cause the heating element to be disengaged from the bottom of the pot body to result in that the heat amount of the heating element is too high, and the heat can not be radiated to burn the heating element is eliminated; thermal efficiency is enhanced, and heat loss is reduced; the average service life of the electric heating pot is more than 5500 hours by testing.

Description

Multi-functional Electric heating cast iron pot

The utility model relates to the kitchen cooker, is specifically related to the Electric heating cast iron pot that family and restaurant use.

It is big that Electric heating cast iron pot has amount of stored heat, and temperature retention time is long, and the cooking food mouthfeel is good and durable in use and advantage such as ferro element needs can effectively be provided for human body, just widely-used in society from the eighties initial stage.The structure of its casting iron pan heating is that electrothermal tube is fixed on bottom of pot body by bolt with little pressing plate of metal or bulk metal pallet.It exists not enough: when the electrothermal tube heating work, bolt, pressing plate or the distortion of pallet expanded by heating of electrothermal tube of being connected is loosening, makes electrothermal tube produce the flexural buckling distortion, can not fit tightly on surface, the bottom of a pan, influenced the heat transmission of electrothermal tube, increased thermal losses bottom of pot body; It is not tight to fit owing to the electrothermal tube distortion and the bottom of a pan are surperficial again simultaneously, has caused the electrothermal tube temperature too high, and heat can not get timely heat radiation, easily the electric furnace heating wire of electrothermal tube is burnt, and has influenced the service life of electric food warmer, and common service life is on average about 1100 hours.

The purpose of this utility model is to provide a kind of raising thermal efficiency, reduces the multi-functional Electric heating cast iron pot of thermal losses and long service life.

The technical solution of the utility model be achieved in that this casting iron pan mainly by the pot body and be connected in its bottom shell and electric heating control device constitute; Its improvements are: be connected in by pad around the electrothermal tube of bottom of pot body, filling is enclosed with the sealing heat-conducting layer.

When implementing technique scheme, different according to two kinds of metal material thermal coefficient of expansions of pot body and electrothermal tube, break for preventing to be welded to connect the position stretcher strain of being heated, be preferably in the electrothermal tube inboard that is connected in bottom of pot body and be provided with pad.

Because bottom of pot body electrothermal tube of the present utility model connects by pad, when the electrothermal tube heating work, pad fits tightly electrothermal tube at bottom of pot body all the time securely, in time heat is transmitted to a pot body; Improved the thermal efficiency, reduced thermal losses, eliminated original connector and broken away from bottom of pot body, caused the electrothermal tube heat too high, can not in time dispel the heat and the phenomenon of burning because of expanded by heating distortion makes electrothermal tube.After tested: service life is on average more than 5500 hours.

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.

Fig. 1 has the front view of cut-away section for the utility model;

Fig. 2 is removal shell 2 and heat-insulation layer 4 among Fig. 1, seals the A-A of heat-conducting layer 6 to cutaway view.

Fig. 1-shown in Figure 2.Being connected in 3 groups of annular electrothermal tubes 5 that vary in size of cast iron pot body 3 bottoms, is by the inboard of brazing contact 8 at every group of electrothermal tube 5, links to each other with pot body 3 bottoms intermittently.Reach the outside between every group of electrothermal tube 5, filling is enclosed with the sealing heat-conducting layer 6 that the cast iron powder constitutes.Shell 2 bottoms are connected with pot body 3 bottoms.Be filled with heat-insulation layer 4 between pot body 3 cylindricals and the shell 2.2 leads 9 that are connected in 3 electrothermal tubes 5 join with electric heating control device 7 circuits that are connected in shell 2 bottoms respectively.

The utility model in use, the temperature of by the switch of operation electric heating control device 7, can realize stewing rice respectively, boiling congee is controlled outage automatically.In addition, also have frying in shallow oil, the cooking function of various food such as explode, rinse, fry, iron.Part 1 is a pot cover.

Claims (1)

1. Electric heating cast iron pot mainly is made of pot body and the shell and the electric heating control device that are connected in its bottom; It is characterized in that: at the electrothermal tube (5) that is connected in a pot body (3) bottom by pad (8) on every side, filling is enclosed with sealing heat-conducting layer (6).
