Detailed description of the invention
Being described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings.The embodiment described below with reference to accompanying drawing is illustrative of, it is intended to is used for explaining the present invention, and is not considered as limiting the invention.
The housing unit 100 of electric heater according to embodiments of the present invention is described below with reference to Fig. 1-Figure 11.
As Figure 1-Figure 11, the housing unit 100 of electric heater according to embodiments of the present invention, including back cover 1, fore shell 2, guard 3, reflector 4 and connector.
Specifically, fore shell 2 is connected with back cover 1 and limits installation cavity 21, fore shell 2 has the open ports 22 connected with installation cavity 21, guard 3 is located at the front side of open ports 22, the outer peripheral edge place of guard 3 is provided with the first mounting lug 32, reflector 4 is located at the rear side of open ports 22, and the outer peripheral edge place of reflector 4 is provided with the second mounting lug 44, and the first mounting lug 32 and the second mounting lug 44 are connected with fore shell 2 by connector.
In assembling process, place fore shell 2, first guard 3 is placed on fore shell 2, then reflector 4 is superimposed upon the top of fore shell 2, be fastened on fore shell 2 finally by disposable guard 3 of connector and reflector 4, then cover back cover 1.The housing unit 100 of electric heater, in assembling process, utilizes that connector is disposable to be fastened on guard 3 and reflector 4 on fore shell 2, simplifies the assembling process of housing unit 100.
The housing unit 100 of electric heater according to embodiments of the present invention, by arranging the open ports 22 connected with installation cavity 21 on fore shell 2, and the first mounting lug 32 is set in the outer peripheral edge of guard 3 and the second mounting lug 44 is set in the outer peripheral edge of reflector 4, and by connector, the first mounting lug 32 and the second mounting lug 44 are linked together with fore shell 2, thus guard 3 and reflector 4 are linked together with fore shell 2, the assembling mode of the housing unit 100 of electric heater can be simplified, improve production efficiency, and readily accessible.
In some embodiments of the invention, the portion perimeter edge of guard 3 stretches in installation cavity 21, and the first mounting lug 32 is folded between the front side wall of reflector 4 and the rear wall of fore shell 2.Thus, guard 3 both can being made to be positioned at the front side of open ports 22, and be easy to again be connected guard 3 together with reflector 4 with fore shell 2, thus simplifying assembling mode, having improved production efficiency.Alternatively, as shown in Figure 4, the first mounting lug 32 and the second mounting lug 44 are multiple and one_to_one corresponding.Thus, it is possible to the reliability increasing guard 3, being connected between reflector 4 and fore shell 2.
During assembling, place fore shell 2, first guard 3 is assembled to open ports 22 from the rear side of fore shell 2, make guard 3 be positioned on front side of fore shell 2 and the first mounting lug 32 is positioned on rear side of fore shell 2, then reflector 4 is superimposed upon the rear side of fore shell 2, first mounting lug 32, between the front side wall and the rear wall of fore shell 2 of reflector 4, is fastened on fore shell 2 finally by disposable guard 3 of connector and reflector 4, then covers back cover 1.The housing unit 100 of electric heater, in assembling process, is absent from rotary movement, is entirely top-down assembling mode, largely avoids the quality problems such as the outward appearance of product scratches, and meanwhile, also without net angle to difficulty operations such as holes, whole assembling process is simple.
