Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a spacer mounting structure provided in a hot air heater.

Conventional technology In the past, hot air heaters were handled because if a guard with a built-in hot air fan attached to the back of the appliance was not kept a certain distance from the wall, the temperature of the appliance would rise or the combustion performance would decrease. In addition to calling for caution in instructions, etc., considerations are being made such as increasing the spacer or stand on the back of the device to ensure a distance from the wall surface. The spacer is mainly made of wire, and has a structure in which it is screwed or hooked onto a cut-out or the like provided on the guard for the appliance or hot air fan.

Problems to be solved by the invention In the above structure, the method of screwing the spacer has problems in terms of workability and high cost, and the structure with a cut-and-raised part for hooking the spacer does not protect the user from fingers, etc. during cleaning and installation. There were some problems, such as the possibility of injury.

Means for Solving the Problems The present invention was developed in view of the above, and includes support holes and holding holes of two different shapes in the upper part of both sides of the hot air fan guard, and a movable structure in the guard. A spacer to be attached is provided with a protrusion and a convex portion corresponding to the irregularly shaped hole, and the protrusion is provided inside the convex portion.

Function Since there are no protrusions such as cut-and-raised parts on the surface, cleaning and installation are extremely safe, and the problems of workability and high cost are eliminated.

Example An embodiment of the present invention will be described with reference to the drawings.

In the figure, 1 is a hot air fan guard provided on the back of the hot air heater, and a fan (not shown) is attached inside. In addition, a fulcrum hole 1a and a holding hole 1 are provided at the top of both sides of the hot air fan guard 1.
b are provided at symmetrical positions. Reference numeral 2 denotes a spacer made of a wire rod for ensuring a distance from the wall surface, and a protrusion 2a and a protrusion 2b are provided at left-right symmetrical positions, and the protrusion 2a is provided inside the protrusion 2b.

The effect of the above configuration will be explained. Insert the tip of the spacer 2 into the fulcrum hole 1a of the hot air fan guard 1. At this time, as shown in FIGS. 2a and 2b, since a certain distance L has been set in advance between the protrusion 2a and the protrusion 2b of the spacer 2, the protrusion 2a of the inserted spacer 2 is in contact with the fulcrum hole 1a. , maintain a certain distance L. Therefore, the convex portion 2b does not come into contact with the surface of the hot air fan guard 1, and the hot air fan guard 1 is not damaged. Next, when the rotation is continued in the direction of the arrow, the protrusion 2a and the fulcrum hole 1a are aligned, and at the same time the protrusion 2b is fitted into the holding hole 1b as shown in Figure 3a and b, and the spacer 2 is attached to the hot air fan. Guard 1
Fixed.

Effects of the Invention As mentioned above, the present invention does not use screws or the like when attaching the spacer, so there is no problem of increased workability or cost.

Furthermore, since there is no protrusion such as a cut-and-raised protrusion on the surface of the guard for hooking the spacer, there is no chance of getting your fingers caught and getting injured during cleaning or installing the spacer.

Furthermore, when the spacer is attached, the convex portion provided on the spacer does not come into contact with the holding hole of the hot air fan guard, so the surface of the guard is not damaged.

Furthermore, when the convex part of the spacer is fitted into the holding hole of the guard, the spacer is securely fitted into the holding hole of the guard due to the spring back generated by the distance L between the convex part and the guard, and the spacer is firmly fitted into the holding hole of the guard. It is fixed and does not wobble.
