Description

Detailed Description of the Invention [Industrial Application Field] The present invention is a hot air dryer that detects a hand held at a predetermined position using a sensor and drives a fan and heater to discharge warm air to the hand position. The present invention relates to a wall mounting structure for a hot air drying device related to device installation technology.

[Conventional technology]

Conventionally used hot air drying apparatuses are generally attached to a wall using a hanging structure formed on the synthetic resin type machine casing itself.

[Problem to be solved by the invention]

However, in this type of hot air dryer, the electric motor and hot air device installed inside the machine casing are extremely heavy, so after installation, the installation posture of the internal devices, especially the electric motor, may be distorted, or the hot air dryer itself may not be properly installed. There were problems such as tilting the aircraft and damaging the machine casing.

The present invention was devised in view of the above-mentioned problems, and an object of the present invention is to provide a wall mounting structure for a hot-air drying device in which the main body of the device is attached so that no load is applied to the internal device of the synthetic resin-type machine casing. It is something to do.

[Means to solve the problem]

In order to achieve the above object, the wall mounting structure of the hot air drying device according to the present invention uses a sensor to detect a hand held over a hot air outlet, and drives a fan and a heater to blow hot air to the hand position. In a hot air drying device that discharges a At the same time, a through hole is formed at a position facing the locking structure on the back surface of the machine casing, and the locking end of the base plate is connected to the machine casing. The gist is that the mount bracket is inserted through the through hole and latched to the latching structure of the mount bracket.

Further, the above base plate can be implemented in the same manner even if it has a structure of directly hanging onto the case of the electric motor.

[Effect]

According to the above-mentioned wall mounting structure, by directly latching and fixing the electric motor with a large load to the base plate, built-in parts with a relatively large load such as a blower and a heater that are fixed to the electric motor can be directly fixed to the wall. This eliminates unnecessary loads on the machine casing. Therefore, even if the machine housing is made of synthetic resin, it will not be deformed or damaged due to concentration of gravity.

At the rear end of the motor 14, a mount bracket 20 made of a substantially rectangular metal plate with a rectangular latching hole 21 bored at its upper end is inserted through the front end of the motor 14. The mount bracket 20 is fixed with a plurality of fixing screws 22, and the mount bracket 20 has a rectangular through hole 23 extending in the vertical direction that is continuous with the through hole 21 for locking, and is bent to form a flat mounting surface 24. At the same time, through holes 26, 26, .
・Thread and tighten the mounting screws 27, 27, etc. inserted from the mount bracket) 20, and fix the blower case 16 via the electric motor 14, the machine casing of the electric motor 14, and the plurality of support arms 28. The hot air fan unit 4 and all the structures fixed to the hot air fan unit 4 are integrated.

The back plate portion 1a of the machine casing 1, to which the mounting bracket 20 is attached to the inner surface, has the four through holes 26, 26...
A recessed step 29 is formed with the inner side recessed toward the front side, and a recessed step 29 is located below the upper edge 31 of the recessed step 29 on the central axis.
A locking end insertion hole 30 of substantially the same shape is bored at a position corresponding to the locking hole 21 of the mount bracket 20, and a pair of holes extending downward are formed along both sides of the insertion hole 30. The guide ribs 32 and 32 form protrusions that are continuous with the widened guide ribs 34 and 34, respectively, via narrow, V-shaped guide ribs 33 and 33 formed in the middle thereof. Further, a groove 35 extending laterally is formed at the lower edge of the recessed step 29, a circular hole 36 for introducing power supply wiring is bored at one end of the groove 35, and a circular hole 36 for introducing power supply wiring is formed at one end of the groove 35. A counterfeit banknote 37 is configured to open a similar circular hole, and a bispout 38 is provided on the lower surface of the side wall of the groove 35 for screwing together mounting screws 41 and 41 from a base plate 40, which will be described later.
．． 38 are bored at predetermined intervals.

The base play) 40 is a JIS standard electrical wiring box 39 used as a general indoor electrical wiring member.
This plate also serves as a cover plate, and is made by bending a flat metal plate, and has multiple mounting screw insertion holes 43. in the four corners and at desired positions.
At the center of the top of the wall mounting plate section 42 in which 43... is drilled,
It constitutes a latching end 44 for latching the latching through hole 21 of the mount bracket 20 bent upward, and also constitutes a bent edge 45 whose lower end is bent forward. A bisport 38 configured on the lower surface of the machine casing 1
．． 38 and corresponding through hole 46.46 for insertion of the mounting screw 41
It is perforated. Reference numeral 47 denotes an electrical wiring processing hole formed at a position corresponding to the groove 35 of the machine casing 1. On both sides of the processing hole 47, there are bulges 4 bent along the groove 35.
8.48 is formed to form a holder for electrical wiring when the base plate 40 is attached to a wall surface.

In addition, at the upper edge of the hooking hole 21 of the mount bracket 20, a member having a U-shaped cross section indicated by the reference numeral 49 is a vibration-proofing rubber made of base rubber, soft synthetic resin, or the like.

When installing the hot air dryer with the above configuration on a wall, the fifth
As shown in the figure, after the base plate 40 is positioned in front of the electrical wiring box 39 and fixed to the wall surface using appropriate mounting screws, the main body of the device is fixed to the base plate 40. At this time, the base plate 40 is The electrical wiring processing hole 47 is fixedly installed between the lower inner walls of the electrical wiring box 39 with a gap G through which the wiring can be inserted. The main body of the hot air drying device is connected from the electrical wiring box 39 to the electrical wiring processing hole 4.

After inserting into the machine case 1 through a circular hole 36 drilled in the back of the machine case 1 and connecting with the terminal block 10, the remaining wiring length is placed inside the electrical wiring box 39 and installed. Mark the position and attach the hooking end 4 of the base plate 40.
4, and then slide it down while pressing it against the base plate 40. This sliding down movement causes the latch end 44 to move towards the narrow guide rib 33.33.
Positioning is performed in the lateral direction along both guide ribs 32.
．． 32, where it falls into the insertion hole 30. A mount bracket 2 is provided inside this insertion hole 30.
Since the through-hole 21 for locking 0 is located, the locking end 44 naturally engages with the edge of the through-hole 21 for locking, and at the same time, at the bottom of the machine housing 1, the through-hole of the bent edge 45 is located. Since the holes 46 and 46 and the screw ports 38 and 38 are made to correspond,
Fasten the fixing screws 41 and 41 from the transparent L46 to the bisports 38, 38 to complete the wall installation.

In the above embodiment, a mount bracket 20 having a through hole 21 for locking is fixed to the electric motor 14, but the through hole 21 for locking may be formed directly on the case of the electric motor 14. Needless to say, the same effect can also be achieved.
