Description
Technical field
The present invention relates to a kind of electric heater parts, particularly relate to a kind of insulating support of electric heater heating coil.
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 partion (metp) 9 in the described frame 1, dividing plate 9 is divided into two parts with the inner space of frame 1.The two ends of described dividing plate 9 are formed with respectively protrudes arm 11, and insert respectively in the through hole on side plate 4 and the side plate 6 at the two ends of protruding arm 11.Described dividing plate 9 is supported on about intermediate altitude of side plate 4 and side plate 6.
The above and below of described dividing plate 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 dividing plate 9 isolate mutually respectively, is electrically connected thereby avoid forming between heat coil 13 and the dividing plate 9.Described insulating support 15 connects and is stuck on the dividing plate 9 by the groove on the dividing plate 9, and stretch out from the upper surface of dividing plate 9 on its top, and stretch out from the lower surface of dividing plate 9 its underpart, and the part that insulating support 15 stretches out the upper and lower surface of dividing plate 9 is symmetrical.
Fig. 3 shows the structure of above-mentioned insulating support 15.As shown in Figure 3, the coil insulation support is symmetry about in the of 15, the position, both sides that the central part that the both sides, middle part are respectively equipped with a groove 16, top and bottom is respectively equipped with a straight elongated slot 17, top and bottom form respectively a spigot surface 19 that tilts to the middle part ', close on a coil stationary groove 19 of spigot surface 19 ' locate to be provided with respectively on the face of the left and right sides.
The degree of depth of described straight elongated slot 17 is about 1/4th of heat coil insulating support 15 length, and its bottom is respectively equipped with a coil stationary groove 18, and coil stationary groove 18 is in sustained height with pairing coil stationary groove 19.
Support effect to 15 pairs of heat coils 13 of above-mentioned heat coil insulating support is illustrated below: (because the heat coil insulating support is symmetrical 15 about, only the situation of its first half being illustrated here)
After being stuck in heat coil insulating support 15 on the dividing plate 9, lead 13a, 13b, the 13c with three adjacent in the heat coil 13 circle coils is pressed into respectively in the coil stationary groove 19 on left side coil stationary groove 19, coil stationary groove 18 and right side by the direction of arrow shown in Figure 3.Lead 13a, 13b, the 13c of three adjacent circle coils just are fixed on pairing coil stationary groove and have suffered in the heat coil 13.According to actual conditions, several such heat coil insulating supports 15 can be installed on the dividing plate 9 simultaneously, heat coil 13 is carried out the multiple spot support, whole heat coil 13 is electrically contacted with dividing plate 9 disengagings fully.
But above-mentioned heat coil insulating support 15 has following shortcoming:
Lead 13a, 13b, the 13c of three adjacent circle coils insert respectively in the coil stationary groove 18 and the process in the coil stationary groove 19 corresponding on the heat coil insulating support 15 in heat coil 13, bigger elastic deformation can take place in heat coil, not only make and insert the task difficulty increasing, and cause sometimes the insecure phenomenon of the support of heat coil.
Summary of the invention
Technical problem to be solved by this invention is, overcome the shortcoming of existing insulating support of electric heater heating coil, provide a kind of simple in structure, easy to operate just, heat coil does not produce deformation, heat coil is provided the insulating support of electric heater heating coil of reliable support in the operating process.
In order to solve the problems of the technologies described above, the technical scheme that insulating support of electric heater heating coil of the present invention adopts is: the rack body of heat coil insulating support is the square dielectric panel of a block length, the left and right sides face central part of rack body is formed with one respectively and is used for location notch, and the effect of location notch is that the heat coil insulating support is fixed on the dividing plate of electric heater; Described rack body is symmetrical structure up and down, is formed with several coils on its upper and lower end face respectively and inserts mouth, inserts mouthful position at each coil and is formed with an insertion groove that extends to the rack body middle part respectively; At least one side of described insertion groove forms the inclined plane, makes insertion groove form shape wide outside and narrow inside; Bottom one side of described insertion groove is formed with a holddown groove respectively.
The direction of described holddown groove is vertical substantially with the direction of insertion groove, and the length of holddown groove should be greater than the diameter of lead in the heat coil.
Describedly between each holddown groove end of rack body top or bottom, be equal to or slightly greater than the pitch of heat coil apart from N.
Described spacing between each coil insertion mouth of rack body top or bottom is less than the pitch of heat coil.
The incline direction on the inclined plane of described each insertion groove should be in the hand of spiral unanimity of heat coil.
The invention has the beneficial effects as follows: simple in structure, heat coil is fixed to heat coil does not produce deformation substantially in the operating process on the heat coil insulating support, greatly reduce task difficulty, be convenient to operation, save man-hour, improve reliability.
