Description

[Detailed description of the invention] The present invention relates to a mounting structure for a humidifier heating element, and in particular, a mounting structure for a humidifier heating element that can prevent the humidifier heating element attached to the humidifier from rotating and preventing vertical movement. Regarding.

Conventionally, in this type of humidifier heating element mounting structure, after the humidifier heating element is attached to the humidifier, the humidifier heating element rotates or moves up and down, causing the humidifier heating element and water tank to interact. There are disadvantages in that sufficient watertightness cannot be ensured at the joint portion of the humidifier, and there is a risk of electrical leakage due to contact between the humidifier heating element and the non-heating element metal part.

The purpose of the present invention is to provide a mounting structure for a humidifier heating element that eliminates the above-mentioned drawbacks. A humidifier heating element is provided with an upper cut-and-raised piece for support and a lower cut-and-raised piece for pipe support having a pipe guide groove, and guided and supported by the upper cut-and-raised piece for pipe support and the lower cut-and-raised piece for pipe support. This is achieved by providing the heating element mounting plate with a pipe fitting for fixing the heat generating element.

Embodiments of the present invention will be described below with reference to the drawings.

1 and 2, reference numeral 1 is a heating element mounting plate attached to the humidifier main body 2, and reference numeral 3 is a water tank installed to the humidifier main body 2.

An upper cut-and-raised piece 4 for supporting a pipe is formed in the upper part of the heating element mounting plate 1 and is cut and raised in a substantially square shape. A rectangular pipe guide hole 5 is provided in the upper cut-and-raised piece 4 for supporting the pipe.

A lower cut-and-raised piece 6 for supporting a pipe is formed in the lower part of the heating element mounting plate 1 and is cut and raised in a substantially square shape. A substantially U-shaped pipe guide groove 7 is provided in the lower cut-and-raised piece 6 for supporting the pipe.

The rising edge 5a of the pipe guide hole 5 and the rising edge 7a of the pipe guide groove 7 have the same rising dimension A from the surface of the heating element mounting plate 1, as shown in FIG.

Further, a pipe mounting fitting 8 is attached and fixed at a position below the pipe supporting lower cut-and-raised piece 6 at the lower part of the heating element mounting plate 1.

The pipe mounting bracket 8 includes a pipe fixing part 9 that fixes a heat generating pipe of a humidifier heating element, which will be described later, and a pipe fixing part 9 having a curvature approximately equal to that of the heat generating pipe, a mounting part 10 fixed to the heat generating element mounting plate 1, and the mounting part thereof. 10 and a convex dowel 12 provided inside the pipe fixing part 9.

In the pipe mounting bracket 8, the pipe fixing part 9 is fastened to the heating element mounting plate 1 by a set screw 13, and the rotation stopper part 11 is engaged with the rotation prevention hole 14 provided at the lower end of the heating element mounting plate 1. It is attached and fixed to the heating element mounting plate 1 so as not to move.

Reference numeral 15 denotes a humidifier heating element attached to the heating element mounting plate 1. The heating element 15 has an insulating paper 17 of a predetermined width wrapped around a heating pipe 16, and a heating wire 18 around the outer periphery of the insulating paper 17. The heating wire 18 is formed by wrapping the protective paper 19 around the outer periphery of the heating wire 18, and wrapping the presser wire 20 around the protective paper. It is connected to a pair of terminal metal wires 21, 21 to be fixed, and lead wires 23, 23 are connected to the pair of terminal metal wires 21 by crimp terminals 22, 22, respectively.

To attach the humidifier heating element 15 to the heating element mounting plate 1, insert the upper end of the heating pipe 16 of the humidifier heating element 15 into the pipe guide hole 5 of the upper cut-and-raise piece 4 for pipe support, and then The lower end of the pipe 16 is fitted into the pipe guide groove 7 of the lower cut-and-raised piece 6 for pipe support, and the pipe fixing part 9 is inserted into the lower end of the heat generating pipe 16.
The humidifier heating element 15 is attached and fixed to the heating element mounting plate 1 by tightening the mounting portion 10 to the heating element mounting plate 1 with the setscrew 13. At this time, the convex dowel 12 of the pipe fixing part 9 of the pipe fitting 8 engages with the recess 24 provided at the lower end of the heat generating pipe 16,
Further, the rotation prevention portion 11 engages with the rotation prevention hole 14 of the heating element mounting plate 1.

The upper end of the heat generating pipe 16 of the humidifier heat generating element 15, which is attached and fixed to the heat generating element mounting plate 1 in this way, is connected to the steam pipe 26 via the connecting pipe 25, and the lower end of the heat generating pipe 16 is approximately It is connected to the water tank 2 via a V-shaped elbow pipe 27.

In this embodiment, the pipe guide hole 5 of the pipe supporting upper cut-and-raised piece 4 is made into a rectangular shape so that the upper end of the heat generating pipe 16 can be inserted and moved up and down within the pipe guide hole 5.
The heat generating pipe 16 may be held in the pipe guide hole 5 itself by making it circular to match the shape of the heat generating pipe 16 and to have a slight spring effect when the heat generating pipe 16 is inserted. .

Further, a spring is applied to the entire pipe fitting 8 so that the pipe fixing portion 9 of the pipe fitting 8 clamps the heat generating pipe 16 when the pipe fitting 8 is fixed to the heating element mounting plate 1 with the set screw 13. It may be configured to provide an effect.

As explained above, the mounting structure of the humidifier heating element of the present invention includes a heating element mounting plate attached to the humidifier, and an upper cutout for pipe support having a pipe guide hole formed in the upper part of the heating element mounting plate. a raised piece, a lower cut-and-raised piece for supporting a pipe having a pipe guide groove formed at the lower part of the heating element mounting plate, an upper cut-and-raised piece for supporting the pipe provided on the heating element mounting plate, and a pipe-supporting piece for supporting the pipe; It is formed from a pipe fitting for fixing a humidifier heating element guided and supported by a lower cut-and-raised piece. Therefore, the parts near the heat generating part of the humidifier heating element are
To minimize contact with the heating element mounting plate, make line contact at the inner circumferential surface of the pipe guide hole of the upper cut-and-raised piece for pipe support and the inner circumferential surface of the pipe guide groove of the lower cut-and-raised piece for pipe support. This has the effect that the humidifier heating element efficiently generates heat by suppressing heat conduction from the pipe supporting upper cut-and-raised piece and the pipe-supporting lower cut-and-raised piece as much as possible.

In addition, the heat generating pipe of the humidifier heating element, which is guided and supported by the upper cut-and-raised piece for supporting the pipe and the lower cut-and-raised piece for supporting the pipe, is fixed by the pipe mounting bracket provided on the heat-generating element mounting plate. Since the humidifier heating element is prevented from rotating and moving up and down after being attached to the heating element mounting plate, it is possible to ensure a reliable and good mounting state of the humidifier heating element.
