The present invention relates to a structure of a wall-mounting base plate in a warm air drying device according to a technology for installing the warm air drying device.

[Conventional technology]

The hot air drying device and the wall mounting structure that have been conventionally used are generally those in which a screw is fastened and fixed to the wall from a mounting rib protruding laterally of the machine casing. Regarding the mounting part on the wall surface, in order to improve the appearance from the front, there are many cases where the mounting structure of the warm air drying device is configured at a part hidden in the back surface of the machine casing, and it is directly connected to the electrical wiring wired in the wall. It is configured to be connected.

[Issue to solve the problem]

Therefore, in this type of hot air drying device in which the wall mounting structure is hidden behind the machine casing, the installation site of the electrical air wiring is difficult to understand because the installation site cannot be seen when installing it, and the position is determined by groping. In addition to the poor workability, there is a problem that water droplets enter the warm air drying apparatus main body from the wall mounting portion through the electric wiring and get wet in the internal apparatus.

The present invention has been made in view of the above problems, and improves the work of connecting electrical wiring, and the wall surface of a hot air drying device in which water droplets from the hot air drying device body do not propagate to the supply side. It is intended to provide a structure for a mounting base plate.

[Means for Solving the Problems]

In order to achieve the above object, the structure of the wall-mounting base plate in the warm air drying device according to the present invention is to detect the hand held over the hot air outlet by the sensor and drive the fan and the heater to position the hand. In a hot-air drying device that discharges warm air to a base, a base plate having a hooking end that engages with a hooking structure formed on the back surface of the machine casing of the main body is a cover for a wall mounting means and an embedded electric wiring box for electric wiring. The main point is to construct a plate.

The base plate is formed by bending a bent edge along the bottom surface of the machine casing of the drying device main body below the hooking end projecting on the plate surface, and tightening between the bent edge and the machine casing with a screw or the like. A fixing means for attaching the electric wiring processing hole is provided, and an electric wiring processing hole is formed near the upper side of the bent edge at a level position corresponding to the inner wall of the bottom surface side of the electric wiring box. A bulging portion for a wire guide is formed on the side, and an upper edge of the electric wiring processing hole is formed so as to hang down to a position inside the portion where the bulging portion is formed.

[Action]

According to the above configuration, the wall surface mounting structure is also used as the cover plate of the electric wiring box embedded in the mounting surface, and is configured on the back surface of the apparatus main body housing toward the latching end of the base plate fixedly mounted on the front surface thereof. The locking structure can be locked and locked.

Similarly, when introducing and connecting the electrical wiring that has been led out to the electrical wiring box into the machine casing, the axial position of the electrical wiring that is regulated by the upper edge of the electrical wiring processing hole of the base plate is below the axial position of the bulging portion. Since the electric wire is pushed down to, the electric wire is formed in a downwardly bent portion before it enters the main body of the hot air drying device and is wired in the upward inclination direction, so that the water flowing through the electric wire flows from the bent portion in the wiring direction. The water does not flow into and the water does not enter the warm air dryer body or the electric wiring box.
