Abstract
The utility model discloses a radiator which comprises a first metal-clad plate and a second metal-clad plate matching with the first metal. An electro-thermal sandwich plate is arranged between both plates and comprises an insulation board and electro-thermal wires winding on the insulation board; insulation cushion plates are arranged between the electro-thermal sandwich plate and the first metal-clad plate and between the electro-thermal sandwich plate and the second metal-clad plate; the second metal-clad plate is provided with a scarfing hole which is provided with an insulation base and the inside of the scarfing hole is provided with a through hole; the electro-thermo wires on the electro-thermal sandwich plates are put through the through hole on the insulation base to lead out. Because the electro-thermal wires are put through the insulation base and lead out from the internal space enclosed by the first metal-clad plate and the second metal-clad plate, the insulation base has features of good insulation and higher melting point, so the short circuit arising from the contact of the joint of leads and electro-thermal wires and the metal-clad plates can be avoided, thereby, improving the safety performance of the radiator.
Description
[technical field]
The utility model belongs to the electroheat technology field, refers in particular to a kind of electric calorifie installation that is used in household appliances.
[background technology]
The heating element that is used on the existing market in the household appliances such as electric cooker, vacuum flask, oven adopts following structure mostly: heating element includes two metal wrapper sheets that cooperatively interact, be provided with at least one electric heating central layer in the metal wrapper sheet, heating wire on described insulation board is constituted by insulation board and uniform winding for it, be provided with insulating pad between electric heating central layer and the metal wrapper sheet, heating wire is drawn by the fairlead of lead-in wire on the metal wrapper sheet and is connected with power line.Because heating wire is directly drawn by the fairlead of lead-in wire on the metal wrapper sheet, lead-in wire causes short circuit with easy the contact with the metal wrapper sheet in joint portion of heating wire, thereby reduce the security performance of heating element, cause the heating element cisco unity malfunction, even cause security incident.
[summary of the invention]
The purpose of this utility model is to overcome the existing defective of common heating element, provides a kind of security performance high heating element.
The purpose of this utility model is achieved in that a kind of heating element, the second metal wrapper sheet that includes the first metal wrapper sheet and cooperate with it, be provided with the electric heating central layer within both, described electric heating central layer is made up of insulation board and the heating wire that is wound on the described insulation board, described electric heating central layer and the described first metal wrapper sheet, be provided with insulating pad between the second metal wrapper sheet, the described second metal wrapper sheet is provided with boarding hole, described boarding hole place is provided with insulating base, be provided with through hole in the described insulating base, the heating wire on the described electric heating central layer is drawn by lead-in wire passes the through hole of described insulating base.
In the above-mentioned heating element, described insulating base is the porcelain seat.
In the above-mentioned heating element, described heating element is provided with feet.
Than common heating element, the beneficial effects of the utility model are: because heating wire is drawn from the inner space that the first metal wrapper sheet and the second metal wrapper sheet are surrounded by lead-in wire passes insulating base, insulating base has the good and higher characteristics of fusing point of insulating properties, joint portion with heating wire touches with the metal wrapper sheet and causes short circuit so can avoid going between, thus the security performance of raising heating element.
[description of drawings]
Below in conjunction with drawings and Examples the utility model is described further.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the enlarged diagram of the A part of Fig. 1.
Fig. 3 is the structural representation of porcelain seat of the present utility model.
[embodiment]
Heating element disclosed in the utility model is generally used in such as in the small household electrical appliances such as electric cooker, slow cooker, vacuum flask, extremely shown in Figure 3 in conjunction with Fig. 1, the second metal wrapper sheet 20 that this heating element includes the first metal wrapper sheet 10 and cooperates with it is provided with electric heating central layer (not illustrating among the figure) within both.The electric heating central layer is made up of insulation board and the heating wire that is wound on the insulation board, and usually, insulation board adopts micarex to make.Be provided with insulating pad (not illustrating among the figure) between the electric heating central layer and the first metal wrapper sheet 10 and the second metal wrapper sheet 20, so that heating wire does not contact with the metal wrapper sheet and causes short circuit.The second metal wrapper sheet 20 is provided with boarding hole 200, and boarding hole 200 places are provided with porcelain seat 30, are provided with through hole 300 in the porcelain seat 30, and the heating wire on the electric heating central layer is drawn by lead-in wire 40 passes the through hole 300 of porcelain seat 30, and is connected with power line 50.Because heating wire is drawn from the inner space that the first metal wrapper sheet 10 and the second metal wrapper sheet 20 are surrounded by lead-in wire 40 passes porcelain seat 30, porcelain seat 30 has the good and higher characteristics of fusing point of insulating properties, 40 touch with the metal wrapper sheet with the joint portion of heating wire and cause short circuit so can avoid going between, thus the security performance of raising heating element.
Lead-in wire 40 can be arranged with fiber sleeve 60 with the connecting portion of power line 50, and is exposed and contact with the metal wrapper sheet with the connecting portion of avoiding both, causes short circuit.
Heating element can be provided with feet 70, so that heating element is installed among electric cooker or the household appliances such as slow cooker or vacuum flask.
Claims (3)
