Description

TECHNICAL FIELD

[0001] The utility model relates to a household electric furnace, especially to a pipe and disc dual-purpose electric furnace. BACKGROUND

[0002] The household electric heating furnace is a kind of household electrical appliance for heating by converting electric energy into heat energy, and is widely used in cooking, heating food, heating and other multiple scenes in family, and its main working principle is to utilize the heat generated by electric current through resistance body (such as heating wire, heating pipe or heating disc and other elements) to heat the surrounding air or food.

[0003] Among them, the electric heating furnace heated by heating pipe adopts resistance wire as heating element, and when working, the electric current passes through the resistance wire to make the resistance wire heat, and then the heated resistance wire heats the kitchenware, so that the heated kitchenware has fast heating speed and concentrated heat, thereby providing strong firepower, so that the electric heating furnace heated by heating pipe is suitable for high-temperature fast cooking, especially for dishes that need strong firepower and fast heating (such as frying, frying, frying and the like) ;

[0004] If the electric heating furnace heated by heating pipe is used to cook soup or stew dishes, the temperature difference between the bottom of the soup body and the top of the soup body is easy to be too large due to the too fast heating speed, so that the problem of uneven heating of food is easy to occur, which reduces the taste of food after cooking, especially for soup that needs long-time stewing, it is difficult to achieve ideal taste and effect;

[0005] And the electric heating furnace heated by heating disc, when heating, first makes the electric current pass through the resistance wire in the heating disc to heat the resistance wire, and then heats the disc body of the heating disc by the heated resistance wire, and finally heats the kitchenware by the heated disc body, so that the heating by heat conduction can make the heat distribution on the heating disc more uniform and stable, so that the electric heating furnace heated by the heating disc is suitable for use in cooking methods that need uniform temperature control and long-time heating (such as stewing, simmering, slow stewing and the like) ;

[0006] If the electric heating furnace heated by heating disc is used to cook food in high-temperature fast cooking mode (such as frying, frying, frying and the like), it needs a long time for preheating, especially for the heating effect of large-area heating disc, which is slow, so that the preheating time is too long, which reduces the cooking efficiency, especially when frying, the temperature rising speed of the kitchenware is too slow, which makes the food material produce too much water, so that the taste and color of the cooked food material are reduced.

[0007] So the electric heating furnace has limitations in the range of use due to different heating methods. UTILITY MODEL CONTENTS

In this way, when the staff uses the electric furnace, the heating element 5 (such as a heating pipe or a heating disc) on the electric furnace can be replaced according to different use requirements, thereby improving the use range of the electric furnace;

[0037] In this way, when the heating element connecting end 51 is connected with the electrode column 6, first, the second conductive column 723 on the second connecting piece 72 is connected with the electrode column 6, then the first connecting piece 71 is connected with the heating element connecting end 51 through the third connecting hole 715 on the first conductive piece 711, and the heating element connecting end 51 is fixed by using the fastening bolt 76, then the heating element connecting end 51 together with the first connecting piece 71 passes through the through hole 21 on the bearing plate 2 into the electric stove main body 1 and is connected with the second connecting piece 72, finally the bearing plate 2 is installed into the through groove 8 through hole 21, and the bearing plate 2 is connected with the electric stove main body 1;

[0038] When the heating element 5 is disassembled, the bearing plate 2 is first disassembled, and the bearing plate 2 is separated from the electric furnace body 1, and then the bearing plate 2 is moved to move the bearing plate 2 on the heating element connecting end 51, so that the bearing plate 2 and the through groove 8 will have a gap, so that the staff can take the first connecting piece 71 connected with the heating element connecting end 51 from the second connecting piece 72 through the gap, wherein in order to facilitate the limiting block 713 into the connecting groove 724, two guide grooves 726 matched with the limiting block 713 are formed on the groove wall of the connecting groove 724, and the guide groove 726 is communicated with the limiting groove 725;

[0039] When the first connecting piece 71 is taken off from the second connecting piece 72, the staff extrudes the limiting block 713 passing through the limiting groove 725, so that the limiting block 713 can be pressed back into the connecting groove 724, and then the staff pulls the heating element 5 to move upward, so that the elastic block 712, the limiting block 713 and the first conductive column 714 are separated from the second connecting piece 72, so that the connection of the heating element connecting end 51 and the electrode column 6 is facilitated by the connection head 7, and because the first connecting piece 71 and the second connecting piece 72 and the elastic block 712 and the limiting block 713 are made of insulating material, and the elastic insulating sleeve 75 is sleeved on the heating element connecting end 51, and one end of the elastic insulating sleeve 75 is connected with the heating element connecting end 51 and the other end is connected with the first conductive piece 711, so that the problem of electric shock during disassembly of the heating element 5 can be reduced, and the elastic insulation sleeve can ensure the fit effect of the insulation sleeve and the heating element connecting end 51 and the first conductive piece 711;
