Abstract
The present invention provides a mounting structure of a fixing plate of an insulating bracket of a heating coil of an electric heater. Two side plates of the electric heater respectively have a slot. The ends of bulging arms of the fixing plate are provided with elastic sheet which integrate the ends, and the end of the elastic sheet upwards tilts. After the ends of the bulging arms of the fixing plate are inserted in the slots on the side plates of the electric heater, the ends of the elastic sheets are pressed on the side plates of the electric heater. The length and the width of the slots are slightly larger than the length and the width of the end surfaces of the bulging arms, and thereby, the ends of the bulging arms can be easily inserted in the slots. The present invention has the advantages of simple structure, convenient work and strong reliability. Besides, the present invention does not influence hot air circulation in air channels of the electric heater.
Description
Technical field
The present invention relates to a kind of electric heater parts, particularly relate to a kind of mounting structure of heating coil insulating bracket securing board of electric heater.
Background technology
The operation principle of general electric heater is: after the energized, heat coil produces heat, takes heat to surrounding space when air flows through the electric heater heating coil.The purposes of electric heater is a lot, and having illustrated among Fig. 1 and Fig. 2 is the internal structure of electric heater that is used for clothesdrier or has the washing machine of drying machine.
As shown in Figure 1, 2, existing electric heater comprises: frame 1, heat coil 13 and insulating support 15.Described frame 1 comprises: base plate 2, the side plate 4 that forms from 2 liang of lateral buckling an angle of 90 degrees of base plate and side plate 6, the slotting door bolt 8 parallel with base plate 2 that forms from the top bending bending an angle of 90 degrees of side plate 4 and side plate 6 respectively.The effect of described slotting door bolt 8 is that electric heater is installed in drying machine one side.Be provided with metal fixed head 9 in the described frame 1, fixed head 9 is divided into two parts with the inner space of frame 1.The two ends of described fixed head 9 are formed with respectively protrudes arm 11, and insert respectively in the through hole 7 on side plate 4 and the side plate 6 at the two ends of protruding arm 11.Described fixed head 9 is supported on about intermediate altitude of side plate 4 and side plate 6.
Protrude structure that arm 11 inserts through holes 7 as shown in Figure 2: observe from the outside of side plate 4,6, the end face central authorities of through hole 7 form the face of depressing 7 to lower recess ', the bottom surface central authorities of through hole 7 form groove 7r with above-mentioned depressing on face 7 ' corresponding position.
The end that protrudes arm 11 be formed with protruding pearl 11 to upper process ', after protruding arm 11 and inserting through holes 7, described protruding pearl 11 ' just in time is by the face of depressing 7 of through hole 7 ' tightly push down.
The above and below of described fixed head 9 is respectively arranged with that several be arranged in parallel, the heat coil 13 of series connection mutually, and 13 head and the tail two ends of coil are connected with power supply terminal 14 respectively, and described power supply terminal 14 is arranged on the described side plate 6.
Described heat coil 13 by supporting with insulation, the insulating support made of heat-barrier material 15, makes heat coil 13 and fixed head 9 isolate mutually respectively, is electrically connected thereby avoid forming between heat coil 13 and the fixed head 9.Described insulating support 15 connects and is stuck on the fixed head 9 by the groove on the fixed head 9, stretch out from the upper surface of fixed head 9 on its top, stretch out from the lower surface of fixed head 9 its underpart, and the part that insulating support 15 stretches out the upper and lower surface of fixed head 9 is symmetrical.
The shortcoming of the mounting structure of above-mentioned existing heating coil insulating bracket securing board of electric heater is: complex structure, installation exercise difficulty, poor reliability.Specifically, want fixed head 9 is installed on the frame 1, the protrusion arm 11 at fixed head 9 two ends is inserted respectively in the through hole 7 on frame 1 biside plate, and make the protruding pearl 11 of protruding arm 11 ends ' by the face that is pressed into 7 of through hole 7 ' push down.Above process operation gets up very difficult.In addition, the protruding pearl 11 that will protrude arm 11 ends ' insertion through hole 7 be pressed into face 7 ' operation in, make protruding pearl 11 ' or be pressed into face 7 ' generation deformation sometimes, cause and protrude arm 11 and can not be securely fixed in the through hole 7, influence installation reliability.
In addition, side plate 4,6 inboards of frame 1 are provided with the air duct along its length direction, and the heat that heater coil 10 produces forms hot blast by the air of above-mentioned air duct.But, can influence the hot blast circulation in the above-mentioned air duct because above-mentioned through hole 7 sizes that form on the side plate 4,6 are bigger.
Summary of the invention
Technical problem to be solved by this invention is, overcome the shortcoming of the mounting structure of existing heating coil insulating bracket securing board of electric heater, a kind of simple in structure, operation convenience, good reliability are provided, do not influence the mounting structure of the heating coil insulating bracket securing board of electric heater that the hot blast in the electric heater air duct circulates.
In order to solve the problems of the technologies described above, the technical scheme that the mounting structure of heating coil insulating bracket securing board of electric heater of the present invention adopts is: be formed with slit respectively on two side plates of electric heater, the end of the protrusion arm of heating coil insulating bracket securing board of electric heater is formed with into a single integrated structure with it flexure strip, and the end of described flexure strip is upturned; Behind the slit on the end insertion electric heater side plate of the protrusion arm of described heating coil insulating bracket securing board of electric heater, the end of described flexure strip is pressed on the electric heater side plate.
The length of described slit and width length and the width than described protrusion arm distal end faces respectively are big slightly, make the end of described protrusion arm can insert described slit smoothly.
Described flexure strip is formed on position, the terminal both sides of described protrusion arm.
Described flexure strip can also be formed on the middle part of protruding the arm end.
The both sides of described protrusion arm can also be formed with several fins.
The invention has the beneficial effects as follows: simple in structure, operation convenience, good reliability, do not influence the hot blast circulation in the electric heater air duct.
Behind the slit on the end insertion electric heater side plate of the protrusion arm of described heating coil insulating bracket securing board of electric heater, the end of described flexure strip just is pressed on the electric heater side plate tightly, make heating coil insulating bracket securing board be securely fixed on the side plate of electric heater frame, installation reliability is extremely strong.
Slit on the electric heater side plate has replaced baroque through hole, and not only structure is simplified greatly, and because the aperture area of slit is very little, the influence that hot blast in the electric heater air duct is circulated is reduced to bottom line.
