Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a glass tube heater for removing frost adhering to a cooler, and more particularly to a mounting device thereof.

2. Description of the Related Art Conventional glass tube heaters As shown in FIG. 6, they were installed between the side plates @ and θ on both sides of the cooler (2). That is, both ends of the drip-proof cover (■) are bent at the bottom of the cooler (■), and the glass tube heater O is attached to this bent piece.
Furthermore, the side plates on both sides of the cooler ■0. Due to the problem that the invention attempts to solve, which is that the drip-proof cover 〇 is fixed to θ, it is not possible to maintain an insulating distance between the cooler ① and the live part of the glass tube heater O. The defrosting water from the cooler (2), which is connected to the lead-in line (theta) of the glass tube heater (O), may enter the live parts and cause an electrical leak. In order to solve this problem, conventional proposals have been made to install a holder for the glass tube heater made of synthetic resin, but it deforms due to the heat generated by the glass tube heater, causing the drip-proof cover to fall off and There are problems that can cause it to fall off.

The present invention is intended to solve these conventional problems, and has a structure that ensures the insulation distance of the glass tube heater, prevents water from entering the glass tube heater, and prevents the glass tube heater from falling off due to thermal deformation. The purpose is to prevent this and to facilitate the installation and removal of glass tube heaters.

Means to Solve the Problems To achieve this object, the present invention makes the holding piece that holds the insulating rubber of the glass tube heater made of synthetic resin, and has a hook having an anchor shape at the tip and a drip-proof cover. A flange is provided, and the glass tube heater is held between the claw of the holding piece of the glass tube heater and the flange that receives the drip-proof cover.

Function: The glass tube heater mounting device of the present invention can separate the cooler and the glass tube heater to ensure an insulation distance.
In addition, by fitting the drip-proof cover to the holding piece, it prevents water from entering the live parts and prevents thermal deformation due to heat generation.
This prevents the glass tube heater from falling off and facilitates installation and removal.

EXAMPLE Hereinafter, an example of the present invention will be described based on the drawings.

As shown in FIGS. 1 to 6, 1 is a cooler, and 2 is a glass tube heater, which is located at the bottom of the cooler 1.

Insulating rubber 3 is provided at both ends of the glass tube heater 2 to hold the glass tube and the heater (details of both are omitted), and lead wires 4 extend from the center. 5 is a drip-proof cover located between the glass tube heater 2 and the cooler 1. The center part of the drip-proof cover 6 is umbrella-shaped, and both ends are bent downward at a point slightly longer than the total length of the glass tube heater 2.
The ceiling is further provided with a flange-backed hole 7. 8 is a holding piece molded from synthetic resin.

The holding piece 8 has an arcuate shape 9 and has a claw 1o at the tip. This nail 1
0 has an anchor shape on the outside. Furthermore, the arc shape 9
There are seven lunges 11 between the and claws 10.

The holding piece 8 is fitted with a locking tool 12 at a position that matches the overall length of the glass tube heater 2, and the dew catcher is locked with a plate 13.

In such a configuration, when the glass tube heater 2 is inserted through the opening of the circular arc 9 of the holding piece 8, the space between 6 and 9 opens outward due to the elasticity of the synthetic resin, and the glass tube heater 2 is The glass tube heater 2 is inserted between the arcuate shapes 90 and returns to the original arcuate shape 9 due to its elasticity. Next, the claw 1o provided at the tip of the holding piece 8 is locked into the hole 7 of the drip-proof cover 5 by the elasticity of the synthetic resin (the state shown in FIG. 6).

At this time, the drip-proof cover 5 is placed on the flange 11 of the holding piece 8.

In this configuration, the glass tube heater 2 is energized to generate heat depending on the application, and is turned off depending on the application. This heat generation causes the synthetic resin holding piece 8 used to deform. arise. This is because materials that utilize the elasticity of synthetic resins are usually thermofusible materials. At this time, the flange 1 of the holder 8
1 is tilted and acts to push up the drip-proof cover 6. As a result, the hook 10 at the tip of the holding piece 8 is inserted into the flange portion 7' of the hole 7 in the drip-proof cover 6 in the shape of an anchor. By preventing deformation in this manner, the drop-off of the drip-proof cover 5 and the glass tube heater 2 is prevented.

In this way, the cooler 1, the glass tube heater 2 with insulating rubber 3 at both ends located at the bottom of the cooler 1, the dew pan 13 placed at the bottom of the glass tube heater 2, and the dew pan 13 and holding the insulating rubber 3 of the glass tube heater 2, a pair of arc-shaped holding pieces 8, and a drip-proof cover 6 formed at the tip of the holding pieces 8 and positioned above the glass tube heater 2. The glass tube is provided with a flange 11 that supports the drip-proof cover, and a claw that passes through the hole in the drip-proof cover and supports the drip-proof cover together with the flange. The structure is such that the heater is held in between.

Effects of the Invention As described above, the glass tube heater mounting device of the present invention provides the following effects.

(1) Insulation for holding the glass tube heater with an insulator is increased, and safety is improved.

(2) Water-proofing of water introduced by the lead wire of the glass tube heater can be achieved with a simple configuration.
