Abstract
A fixing structure of a heater coil includes a fixing plate fixing the coil heater, a supporting component supporting the coil head-out part to prevent the coil lead-out part from sagging. This invention designs an insulation-supporting component to support the lead-out part to prevent it from sagging and increase the insulation of the heater coil.
Description
Technical field
The present invention relates to a kind of fixed structure of heater coil.
Background technology
As shown in Figure 1, existing coil type heater is by heater case 10, fixed disk 20, a plurality of insulators 30, heater coil 40, heater button 50 compositions such as grade.The both sides of heater housing 10 are respectively equipped with fluid input port 11 and fluid discharge outlet 12; In order to divide the inner space of heater case 10 equally, fixed disk 20 is installed in heater case 10 inside; A plurality of insulators 30 are fixed on the fixed disk 20 and keep certain interval with the inside of heater case 10; Heater coil 40 parts are supported in above-mentioned insulator 30, add the fluid that heat flow; Heater button 50 is connected with heater coil 40, to control its energising.
One side of above-mentioned heater case 50 is equipped with 3 buttons, from top to bottom called after the 1st heater button 51, the 2 heater buttons 52, the 3 heater buttons 53.
Above-mentioned heater case 10 inside are equipped with 2 heater coil 40, general called after the 1st heater coil 41 and the 2nd heater coil 42.
If a plurality of insulators 30 that are installed in heater case 10 inside are divided equally when fluid input port 11 sides and fluid outlet 12 sides, be supported in the 1st heater coil 41 of fluid input port 11 side insulators, one side is connected in the 1st heater button 51, and opposite side is connected in the 2nd heater button 52.The 2nd heater coil 42, one sides that are supported in fluid discharge outlet 12 side insulators 32 are connected in the 1st heater button 51, and opposite side is connected in the 3rd heater button 53.
The top lead division 42a that the part of the 2nd heater coil 42 that is connected with above-mentioned fluid discharge outlet 12 side insulators 32 upsides with the 1st heater button 51 is called heater coil 42 here; The bottom lead division 42b that the part of the 2nd heater coil 42 that is connected with fluid discharge outlet 12 side insulators 32 downsides with the 3rd heater button 53 is called heater coil 42.
In order to insulate, the heater coil 42 upper and lower lead division 42a being supported in above-mentioned fluid discharge outlet 12 side insulators 32 are wound with some ceramic rods on the 42b.
The course of work of existing coil type heater with said structure is as follows.
When air enters cavity by fluid input port 11, when power supply and the 1st heater button 51 were connected, above-mentioned the 1st heater coil 41 that is connected in the 1st heater button 51 and the 2nd heater button 52 began heating; Meanwhile, also begin heating with the 2nd heater coil 42 that the 1st heater button 51 is connected with the 3rd heater button 53.
Therefore, enter heater coil 41,42 heating that the air of cavity is generated heat, from fluid discharge outlet 12, discharge then.
In existing coil type heater, in order to insulate, the upper and lower lead division 42a of the 2nd heater coil 42 is wound with ceramic rod on the 42b.Because of the deadweight of ceramic rod increases the weight of each lead division, so on each lead division, sagging takes place.
Particularly, bottom lead division 42b's is sagging even more serious compared with top lead division 42a.This is because the sagging of bottom lead division 42b alleviated the sagging of top lead division 42a to a certain extent, so the sagging amplitude of top lead division 42a is less, and the sagging amplitude of bottom lead division is bigger.
The thermal expansion that causes because of the heating of heater coil 42 more increases the weight of above-mentioned each lead division 42a, and 42b's is sagging.
Therefore, the bottom lead division 42b of the 2nd heater coil 42 contacts with heater case 10, makes that the insulating properties of the 2nd heater coil 42 is destroyed.
Summary of the invention
In order to overcome the above-mentioned shortcoming that existing winding heater exists, the invention provides a kind of fixed structure of heater coil, it is provided with lead division that an insulating support member supports heater coil preventing the sagging of lead division, and improves and improve the insulating properties of heater coil.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of fixed structure of heater coil is characterized in that comprising the fixed disk that is fixed on the coil type heater, supports the support component of heater coil lead division, to prevent the sagging of heater coil lead division.
The fixed structure of aforesaid heater coil, wherein support component is by the body part that is fixed on fixed disk, for body part being fixed on the holddown groove that fixed disk forms in the body part both sides, be positioned at the vertical top of body part, support the support slot of described heater coil top lead division, be positioned at the vertical below of body part, support the bracing ring of heater coil bottom lead division and form.
The fixed structure of aforesaid heater coil, wherein an end of support component coil is fixed on the fixed disk, and another section is fixed on described heater coil bottom lead division, forms lead.
The fixed structure of aforesaid heater coil, wherein support component is made by insulating material.
