Description

[Detailed Description of the Invention] The present invention relates to a holding device for a heating element used for room heating.

A conventional heating element holding device in a hot air heater is provided with a reflector having a parabolic cross section in the front opening of the frame, and each heating element is attached to a linear spring at the focal point of the reflector. Further, each heating element is connected and fixed to each terminal board of a terminal block made of an insulating material provided on the side plate of the reflector.

However, the heat generating element protection device in the hot air heater described above has a large number of parts and is complicated to assemble because both ends of each heat generating element are fixed with individual springs. However, the outer diameter of the quartz glass of the heating element, which is constructed by passing a heating wire through a quartz glass tube, varies widely, and there is a risk of breakage even with the slightest external force. Since different springs of the same shape must be prepared in advance, uniform retention cannot be obtained and it is difficult to achieve labor savings through mass production.

In order to solve the above-mentioned difficulties, the present invention provides elastic wires to be wound around each heating element that is mounted by passing through the side plate of the reflector and the terminal block attached to the side plate. The purpose of this is to hold each heating element quietly regardless of variations in the outer diameter of each heating element, reduce the number of component parts, facilitate assembly, and save labor through mass production. There is a hot air heater available.

Hereinafter, the present invention will be described with reference to an illustrated embodiment.

In FIGS. 1 to 4, reference numeral 1 denotes a main body frame of the hot air heater, and a reflector 2 whose cross section is in the shape of a parabolic line is provided at the front port 1a of the main body frame 1. , a plurality of blow-off holes 3 are bored approximately at the center of the reflector 2 .

Further, a blower 4 is attached to the inside of the body frame 1 located at the back of the blow-off holes 3, and the fluid from the blower 4 is blown forward through the blow-off holes 3. There is.

Furthermore, the opening 1 located in front of the blowing hole 3
A guard 5 is installed over the reflector 2 to prevent an alligator finger or the like from being accidentally inserted into the reflector 2.

Further, a pair of leg rods 6 are provided at the bottom of the main body frame 1 to prevent the main body frame 1 from falling down, and a main switch 7 is provided at the top of the main body frame 1.

On the other hand, each through hole 8 is bored in the both side plates 2a of the reflector 2 at the focal point of this reflector 2.
A heating element 9 constructed by passing a heating wire 9b through a quartz glass tube 9a is mounted therethrough.

In addition, the above-mentioned both side plates (only one side is shown in the figure) 2a
As shown in FIGS. 3 and 4, each cut and raised groove 10 is provided in the middle, and each cut and raised groove 10
A terminal block 11 made of an insulating material is detachably attached to the terminal block 11 .

Furthermore, each terminal terminal plate 12 is fixed to this terminal block 11, and each end portion 12a of each terminal terminal plate 12 is connected to the heating element 9.

In addition, each lead wire 13 is attached to each terminal board 12 mentioned above.
Each leap line 13 is connected to a power source via the main switch T.

On the other hand, each cut-and-raised locking piece 14 is provided at a position close to each corner of the side plates 2a, and each cut-and-raised locking piece 14 has each elastic wire 15. Guide groove 111 of the heating element 9 and the terminal block 11! It is provided so that it can be wrapped in a bird-like shape.

Therefore, each of the elastic wires 15 can be attached to each heating element 9 and the terminal block 11 without fixing them with mounting screws or the like.
It is designed to be fixed and held.

That is, the terminal block 11 is held by the wire 15, and each heating element 9 is quietly fixed by the wire 15 and each terminal board 12.

As described above, according to the present invention, a pair of heating elements 9 are mounted in parallel through the side plates 2 of the reflector 2 whose cross section is in the shape of a parabolic line. .

A terminal block 11 is mounted in the middle, and an elastic wire 15 is wound around each end of the terminal block 11 and the heating elements 9 in a staggered manner, and both ends of the wire 15 are attached to the side plate 2. ．． The terminal block 11 and each heating element 9 are elastically fixed and held by the only wire rod 15 because it is elastically attached to a pair of cut and raised engagement pieces 14 formed in the l. Not only is this possible, but even if there are variations in the outer diameter of the quartz glass tube 9a, it can be assembled without causing any inconvenience.
Since there is no risk of applying excessive external force, there is no risk of damage, and it has excellent effects such as being able to be fixed quietly with a uniform holding force.
