Abstract
The utility model relates to an automatic constant temp. electric heating preheater for an engine oil drain pan, which is composed of a one-way electric heating assembly and a control part. The one-way electric heating assembly which is composed of an electric heating element, an insulating sheet, an insulating chamber and a heat conducting metal sheet is fixed in a case by screws, and the shape and the size of the one-way electric heating assembly are matched with the engine oil drain pan. The control part which is composed of a temperature control element and a microswitch can automatically control the opening and the closing of the microswitch through the deformation of the temperature control element to achieve the constant temperature. The utility model has the advantages of simple structure and easy use, and solves the problem that the motor vehicle is not easy to start because the engine oil is solidified in winter.
Description
The utility model relates to a kind of automatic constant-temperature electric heater, is used for the heating of Motor Vehicle oil pan.
At present, motor vehicle are in cold winter, and because of no garage, tie in the machine oil of motor east, start very difficultly, adopt naked light to heat mostly, machine oil is melted to engine sump tank, ato unit, this method are not only inconvenient but also waste energy dangerous fire hazardous.
The purpose of this utility model is to propose a kind of suitable various rectangle oil sump engine motor oil automatic constant-temperatures and adds the thermoelectron device, thereby solves motor vehicle because of there not being the garage winter, starts the problem of difficulty.
Major technique content of the present utility model is, the hot device of this automatic constant-temperature oil pan electric heating, form by unidirectional electrical heating assembly and control section, unidirectional electrical heating assembly is by electric heating element 18, upper insulation plate 17, lower insulation plate 19, adiabatic chamber 10, thermal conductive metal plate 15 constitutes, in the middle of electric heating element is positioned at, it above it upper insulation plate, be lower insulation plate below, both sides are convection current air flue 14, the top of upper insulation plate is thermal conductive metal plate, and the following and both sides of lower insulation plate are adiabatic chamber, are connected as a single entity, be fixed in the housing 1 by fastening screw trip bolt 16, its geomery is corresponding with the rectangle oil pan; Control section is positioned at the left side of unidirectional electric heating assembly, is made up of sensitive switch 6, heat responsive element 9, control room 5, power plug 3, power supply input chamber 2; The electric heating element lead-in wire hole by adiabatic chamber left sideboard 13 enters the control room and is connected with power input plug with the sensitive switch that is installed in control room lower clapboard 4, and cooperate with heat responsive element on being installed in control room upper clapboard 8, the heating of realization automatic constant-temperature is connected with the oil pan contact by elasticity card base 14.After inserting power supply, electric heating element heats up, its heat forms folk prescription to oil pan is conducted convection heating by convection current air flue and thermal conductive metal plate, other directions are because the heat insulating function of adiabatic chamber only distributes micro-heat energy, when oil temperature is elevated to when adjusting temperature, the distortion of heat responsive element bimetallic strip generation directional curvature drives the power supply that sensitive switch cuts off heating element, stops heating; When temperature is reduced to setting valve when following, the distortion of heat responsive element bimetallic plates reduces and returns to original position, and sensitive switch its break contact under the return spring effect is connected power supply, to electric heating element energising heating, temperature is risen, and reaches the purpose of constant temperature like this.
Technique effect of the present utility model is, the hot device of this automatic constant-temperature oil pan electric heating, its structure is to adopt unidirectional electric heating assembly and control unit to constitute, have simple in structure, advantage easy to use, can directly be loaded on the oil pan of motor vehicle machine oil is added heater heat, not need motor vehicle are carried out any transformation.Keep machine oil not solidify at low temperatures, having solved cold winter motor vehicle does not have the problem that the garage starts difficulty.This device use occasion is extensive in addition, as long as there is the place of Ac all can use, and safe and reliable.
Fig. 1 is the utility model cross-sectional view;
Fig. 2 overlooks cross-sectional view for the utility model;
Fig. 3 is the utility model circuit theory diagrams.
1 housing, 2 power supplys input chamber, 3 power plugs, 4 control room lower clapboards, 5 control rooms, 6 sensitive switches, 7 control room upper clapboard footing, 8 control room upper clapboards, 9 heat responsive elements, adiabatic chambers 10,11 temperature control adjusting screw, temperature- sensitive chambers 12,13 adiabatic chamber left sideboards, 14 elasticity card bases, 15 heat conduction boards, 16 fastening screw trip bolts, 17 upper insulation plates, 18 electric heating elements, 19 lower insulation plates, 20 convection current air flues, 21 and the engine sump tank surface of contact.
Realize scheme of the present utility model as shown in the figure.
Hot device is given in this automatic constant-temperature oil pan electric heating, and the heating-up temperature setting valve is controlled at and is lower than the machine oil ignition temperature promptly below 100 ℃; Its adiabatic chamber adopts heat-resisting powder and an amount of binder to be mixed and made into, or directly in the dried housing of molding, heat conduction board adopts cast iron plate, makes less than the rectangular plate of adiabatic chamber and hole, two gardens is arranged in order to fastening with housing; Heating element is made rectangular plate shape, and the adiabatic and insulation to housing is realized with micarex high temperature resistant and insulation in the two-berth.
Heat responsive element adopts bimetallic plates, is installed on the upper clapboard in control room, and its fastening foot is a sheet metal that slotted hole is arranged, by screw on the upper clapboard in control room, but and be the center move left and right with the screw hole, in order to the control temperature value of adjusting.The control temperature difference of the hot device of this automatic constant-temperature oil pan electric heating can reach 40 ℃.
