Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a heater that can be used for both convection and reflection heating by having a removable reflector plate.

[Conventional technology]

Convection type heaters are unique in that they are placed in the center of the room and emit heat rays to the surrounding area, warming the indoor air and collecting warmth, but they are sometimes placed near the walls of the room, and in such cases This causes the walls to heat up. For this reason, a removable reflector is installed to reflect the heat rays directed toward the wall toward the center of the room. Publication No. 57-24411, Utility Model Application No. 59
-See Publication No. 4912.

[Problem that the invention aims to solve] By the way, conventional removable reflectors are compatible with specific heaters, and if the heater was manufactured in a different year or by a different manufacturer, it may not be possible to use a reflector obtained as an optional cutter. It disappeared and was not easy to use.

[Means to solve problems]

This idea proposes a structure that allows extremely large tolerances in the dimensions of the mounting part when attaching the separately sold reflector frame to a convection heater, and houses the heat generating part inside the heater frame. In a heater in which a guard is arranged around the heater frame, and a reflector frame is attached to the heater frame or the guard with a pair of locking plates, at least one of the locking plates is attached to the heater frame or the guard. A locking plate fulcrum that rotatably holds the plate on the reflector frame; a movable plate that is screwed onto a screw loosely fitted into a mounting hole of the reflector frame and moves when the screw rotates; and a movable plate that engages with the movable plate. A driving piece of the locking plate is provided so that the locking plate, which rotates via the driving piece as the screw rotates, locks on the heater frame or the guard and fixes the reflector frame. This is what I did.

[Effect]

The heater of this invention is of the commonly used convection type, and the heating part is housed inside the heater frame.
Heat is radiated from the heat generating part to the surroundings. This heat radiation is carried out all around the heater, and as a result, if the heater is installed close to a wall, the temperature of the nearby wall will become high, which is extremely dangerous. As a countermeasure for this, a removable reflector frame is attached to the heater for safe use, but the locking plate that connects the reflector frame and the heater in this invention is attached to the reflector frame. The locking plate is rotatable about the provided locking plate fulcrum, and the locking plate is rotated by operating the driving piece of the locking plate.

On the other hand, the movable plate is screwed into the screw that loosely fits into the mounting hole of the reflector frame, and when the screw is rotated, the positional relationship with the loosely fitted mounting hole does not change, and the movable plate stops its own rotation. to move back and forth along the thread. Since the movable plate and the driving piece of the locking plate are engaged with each other, when the movable plate is moved by the rotating screw, the driving piece of the locking plate is operated, and the tip of the locking plate moves a large distance. At this time, the pair of locking plates clamp the heater frame and the guard, thereby fixing the reflector frame to the heater frame.

〔Example〕

This invention will be explained with reference to the embodiment shown in the figure. 1 is a heat generating part housed inside the heater frame 5; 2 is a guard disposed around the heat radiating part of the heater frame 5;
Reference numeral 4 designates a pair of locking plates for attaching the reflector frame 3 to the heater frame 5 or the guard 2. 7 is a locking plate fulcrum that is the center of rotation of the locking plate 4 formed on the reflector frame 3; the locking plate fulcrum 7 in the embodiment is a U-shaped mounting plate installed inside the reflector frame 3; A hole drilled at the corner of No. 10 and a locking plate protrusion 4b that fits into the hole.
It consists of

9 is a screw loosely fitted into the mounting hole 3a formed in the reflector frame 3; (8) is a movable plate screwed together with the screw 9;
When the screw 9 is rotated, since the screw 9 and the mounting hole 3a are loosely fitted, the screw 9 rotates freely and the positional relationship between the screw 9 and the reflector frame 3 does not change. Further, the movable plate 8 screwed together with the screw 9 can be moved back and forth along the thread by rotating the screw 9 while the movable plate 8 is stopped rotating. 4a is a driving piece of the locking plate 4 that rotates around the locking plate fulcrum 7, 7a is an engagement hole drilled in the movable plate 8, and the tip of the driving piece 4a is fitted into the engagement hole 7a. When the movable plate 8 moves back and forth, the driving piece 4a is moved through the engagement hole 7a, and the locking plate 4 is rotated.

6 is a locking piece at the tip of the locking plate 4 that locks with the heater frame 5 or the guard 2, and when the heater frame 5 and the reflector frame 3 are positioned at a constant interval and the screw 9 is turned The pair of locking plates 4 can be rotated to narrow the gap, and a part of the guard 2 and the heater frame 5 can be clamped and fixed between the tip locking pieces 6.

In addition, although the drawing of the embodiment shows a structure in which both of the pair of locking plates 4 rotate together, one of the locking plates 4
Even with a structure in which the locking plate 4 is fixed and only the other locking plate 4 is rotated, the reflector frame 3 can be fixed to the heater frame 5.

〔effect〕

As described above, in this invention, the tip locking part 6 of the locking plate 4 can be moved largely by the rotation of the screw 9, so that the reflector frame 3 can be attached to the heater frame 5 as in the conventional product. Rather than sticking to a specific position,
An arbitrary clamping position can be selected using the tip locking part 6, and even if the manufacturing year or manufacturer of the heater differs, the heater can be securely secured, making it extremely easy to use. .
