  By the way, in this conventional thing, it fixes by making a nail fit to a square hole, but when some load was applied to the nail in this fixed state, there was a problem that a nail will come off from a square hole. .

  In order to solve the above-mentioned problems, in the first aspect of the present invention, the operation unit mounting bracket fixed in the main body is attached to the operation unit unit and the receiving unit. The insertion claw of the insertion unit, the insertion claw hole into which the hook claw is inserted, and the hooking claw hole are formed, and an insertion claw in which one end of the operation unit unit is positioned on the insertion claw hole and fitted into the insertion claw hole Is close to

  According to a second aspect of the present invention, the hooking claw comprises a substantially L-shaped hooking part and a hooking part base part of the base part of the hooking part, and the hooking part base part is provided with substantially the same size as the hooking claw hole. Is.

  According to the first aspect of the present invention, an insertion claw hole and a hooking claw hole into which the insertion claw and the hooking claw of the receiving unit are inserted are formed in the operation unit mounting bracket, and one end of the operation unit unit is used for the insertion claw. Since it is close to the insertion claw that is located on the hole and fitted in the insertion claw hole, if the insertion claw is subjected to some load and is bent, the insertion claw abuts against the tip of the fixed part of the operation unit. Thus, the wedge-shaped portion of the insertion claw does not come off from the insertion claw hole, and the insertion claw can be prevented from coming off.

  According to a second aspect of the present invention, the hooking claw comprises a substantially L-shaped hooking portion and a hooking portion base portion of the base portion of the hooking portion, and the hooking portion base portion is provided with substantially the same size as the hooking nail hole. Therefore, when the hooking nail is attached to the hooking nail hole, the hooking base of the hooking nail engages with the hooking nail hole, so that the hooking nail does not move in the direction away from the hooking nail hole, and the hooking nail Can be prevented from coming off.

Next, a hot air heater according to the present invention will be described with reference to an embodiment shown in the drawings.
Reference numeral 1 denotes a substantially rectangular parallelepiped hot air heater body, and an open / close shutter 3 for opening and closing a hot air outlet (not shown) is provided at the approximate center of the front panel 2 on the front, and the upper center of the front panel 2 is approximately centered. Is provided with a display unit 4 for displaying temperature such as set temperature and room temperature, time, alarm, and other information, and further on the upper right side of the front panel 2 is a signal when a remote control (not shown) is operated. A receiving sensor 5 for receiving is provided.

  Reference numeral 6 denotes an operation unit, which includes an operation unit main body 7 made of a synthetic resin and a switch unit 9 attached to the upper surface of the operation unit main body 7 and provided with various switches such as an operation switch 8. 7 are provided with fixing portions 11 in which fixing screw holes 10 are formed.

  Reference numeral 12 denotes a receiving unit unit made of a synthetic resin, and includes a substrate mounting part 13 to which a receiving board (not shown) provided with the receiving sensor 5 is attached, and a receiving part mounting part 14 provided on the upper part of the substrate mounting part 13. Thus, a substantially wedge-shaped insertion claw 15 is provided on the outer side of the hot air heater body 1 of the receiver mounting portion 14, and a substantially L-shaped hook is provided on the inner side of the hot air heater body 1. A hooking claw 18 comprising a portion 16 and a hook base 17 at the base of the hook 16 is provided.

  Reference numeral 19 denotes an operation unit mounting bracket, which is composed of a vertical surface and is fixed to the frame of the hot air heater main body 1 with screws (not shown), and the main body frame mounting surface 20 An operation unit mounting surface 21 configured to be a horizontal plane and to which the operation unit unit 6 is mounted; a display unit mounting surface 22 configured to be substantially perpendicular to the operation unit mounting surface 21 and mounting the display unit unit 4 at a substantially center; The side mounting surface 23 is formed on both ends of the portion mounting surface 21 and fixed to the frame of the hot air heater body 1 with screws (not shown). An operation fixing hole 25 for fixing the portion 6 with a screw 24 is formed, and an insertion claw hole 26 into which the insertion claw 15 of the reception unit 12 is inserted, and a reception unit at the right end portion of the operation unit mounting surface 21. Hole for hook nail into which 12 hook claws 18 are inserted 7 in which is formed.

Next, the attachment structure of the receiving part 12 of a present Example is demonstrated.
First, the operating portion mounting bracket 19 is fixed to the frame of the hot air heater body 1 with screws, and the hooking portion of the hooking claw 18 of the receiving unit 12 is inserted into the hooking claw hole 27 of the fixed operating portion mounting bracket 19. 16 with the hooking portion 16 of the hooking claw 18 hooked in the hooking claw hole 27, the insertion claw 15 of the receiving unit 12 is inserted into the insertion claw hole 26, and the receiving portion is inserted into the operation portion mounting bracket 19. 12 is fixed.

  At this time, since the insertion claw 15 has a substantially wedge-shaped tip, when the insertion claw 15 is inserted into the insertion claw hole 26, the insertion claw hole 26 abuts against the wedge-shaped part of the insertion claw 15 to push and bend the insertion claw 15. When the insertion claw 15 is inserted to a predetermined position, the insertion claw hole 26 that is in contact with the wedge-shaped portion of the insertion claw 15 is positioned at a narrow portion of the wedge-shaped neck portion and is pushed and bent into the insertion claw hole 26. When the inserted insertion claw 15 returns to the original state, the insertion claw 15 cannot be removed from the insertion claw hole 26, and the receiving unit 12 is fixed to the operation unit mounting bracket 19.

  At this time, the hooking claw 18 has a direction in which the hooking claw 18 is detached from the hooking claw hole 27 because the hooking base 17 having the same size as the hooking claw hole 27 is engaged with the hooking claw hole 27. Therefore, it is possible to prevent the hooking claw 18 from coming off.

  Then, the operating unit unit 6 is placed on the operating unit mounting surface 21 of the operating unit mounting bracket 19, and a screw 24 is inserted into the fixing screw hole 10 of the fixing unit 11 of the operating unit unit 6. The operation unit 6 is attached to the operation unit mounting bracket 19.

  At this time, the gap between the distal end of the fixed portion 11 of the operation unit 6 and the insertion claw 15 is about 0.5 mm. When the insertion claw 15 is subjected to some load and is bent and bent, the insertion claw 15 is moved to the operation unit unit. 6, the wedge-shaped portion of the insertion claw 15 does not come off from the insertion claw hole 26, thereby preventing the insertion claw 15 from coming off.

  As described above, in the structure in which the hook is fixed by fitting the claw into the square hole, and the structure in which the hook claw 18 is fixed in the hook claw hole 27, the hook base 17 of the hook claw 18 is fixed. Is approximately the same size as the hooking claw hole 27 and the hook base 17 is engaged with the hooking claw hole 27, so that the hooking claw 18 does not move in the direction away from the hooking claw hole 27 and is hooked. It is possible to prevent the nail 18 from coming off.

  In the structure in which the insertion claw 15 is fixed by fitting the insertion claw 15 in the insertion claw hole 26, when the insertion claw 15 is subjected to some load and is pushed and bent, the insertion claw 15 is fixed to the fixing portion 11 of the operation unit 6. The wedge-shaped portion of the insertion claw 15 is prevented from coming off from the insertion claw hole 26 and the insertion claw 15 can be prevented from coming off.

  Therefore, it is possible to prevent the receiving unit 12 from being detached from the operation unit mounting bracket 19 without directly attaching the receiving unit 12 to the operation unit mounting bracket 19 with screws or the like.
