Abstract

PURPOSE:To make a nozzle head thinner and enable a projected degree from a wall surface, to be diminished by setting a hook-engaging means to be an engaging projection engaged with the internal surface of the discharge port of the nozzle head. CONSTITUTION:A nozzle head 2 at the tip of a hose 3 led from an air blower 1 is contained by fitting the nozzle head 2 into a recessed section 18 formed at the air blower 1. When the nozzle head 2 is fitted into the recessed section 18, then a magnetic plate 31 is attracted by a permanent magnet 35, and an engaging projection 36 is engaged with the internal surface of a discharge port 23 through a lattice 25. Accordingly, on the nozzle head 2, a salient section is not required to be set, and so the nozzle head 2 can be made thinner, and also when the head 2 is hook-engaged with the blower 1, then the projected degree from a wall surface can be diminished.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a wall-mounted hair dryer that is used by being attached to a wall in a washroom or the like. [Prior art] In a wall-mounted 7-piece dryer, there is a 7-piece wall-mounted dryer.
A nozzle head with a discharge port is installed at the end of the hose led out from the blower, and the hot air sent out from the blower is guided to the discharge outlet [1] of the nozzle head through the hose. It will be destroyed. Here, in order to facilitate the storage of the nozzle head when not in use, there is a device in which the nozzle head can be hooked and locked to the blower, for example, in the Utility Model Publication No. 55-608.
This method is disclosed in Japanese Patent Publication No. 06 and Japanese Patent Application Laid-Open No. 61-244306. In other words, a protrusion whose tip end is a discharge port is provided protruding from one surface of the nozzle head, and a recess is formed in the blower to accommodate this protrusion, and when not in use, the protrusion is By placing it in the recess, the lower surface of the protrusion is received by the blower. [Problem to be solved by the invention] In this case, the thickness of the nozzle head increases by the amount that a protrusion must be provided on the nozzle head, and as a result, the amount of protrusion from the wall surface when hooked onto the blower. Moreover, since the ejection port of the nozzle head is located in a protruding portion called the tip end surface of the protrusion, there is a problem α in that it is not easy to use. The present invention has been developed by O: as described above,
The purpose of this is that even when the nozzle head is hooked onto the blower and stored, the amount of protrusion from the wall is small so it does not get in the way, making it easy to use! + Provides a soaked wall-mounted hair dryer. [Means for Solving the Problems] Accordingly, the present invention includes an air blower having a built-in fan and a heater, and a flexible hose that is provided at the tip of a flexible hose led out from the air blower, and is provided with a discharge port on one side. In a dryer with a nozzle head and a ratchet 9, the blower is equipped with a hooking and locking means for the nozzle head, and in a dryer, the hooking and locking means is a locking protrusion that locks on the inner surface of the discharge port of the nozzle head. It has the following characteristics. [Operation 1] According to the present invention, since the inner surface of the discharge port of the nozzle head is used to hook and lock the air blower, there is no need to provide a protrusion on the nozzle head, and the nozzle head can be made thinner by the amount of the protrusion. be able to. [Example 1] The present invention will be described in detail below based on the illustrated embodiment.

It is composed of. The blower 1 is 1 as shown in Fig. 3, rPJ6 and Fig.7.
A container body is constituted by the base housing 10 and the cover 11, and a space surrounded by the wind tunnel casing part 12 and the casing 13 in the base housing 10 is formed in the upper part of the container body. A multi-blade centrifugal type 7-an 4 rotatably driven by a motor 40 is installed in the center, and a heater block 5 is installed adjacent to the opening facing the lower surface of the vessel. Above 7
The T-ton 4 draws air from a suction port 14 formed on the side of the cover 11, shown in FIG. It is sent out to the opening on the bottom surface of the container body where the block 5 is arranged. At this time, from the green of the opening 16 in the casing 13,
An annular backflow prevention piece 17 with a diameter smaller than the inner diameter of the blade of the 77-in 4 is protruded, and the rad 2 is attached to the hose 3 and nozzle.
As shown in FIG. 3, the backflow prevention piece 17 prevents backflow toward the suction port 14 due to an increase in the pressure in the space due to pressure loss on the side. In addition, the 7-an 4 shown here has a support plate for its blade part only on the side opposite to the opening 16, and compared to the one with support plates on both sides, The vent hole 45 provided in the support plate shown in FIGS. This prevents the flow from returning to 4111 and causing turbulence. 41 in the tjS3 diagram is the motor mounting plate, 7 in the tIS6 diagram
is a circuit block, and 8 is a switch block. The light-emitting display element and the manual production section arranged on the surface of the circuit block 7 face the front of the cover 11 and constitute a fabrication display section 9. The other end of the hose 3, which has a nozzle rad 2 attached to its tip, is connected to the opening located on one side of the lower surface of the blower 1, and a nozzle is connected to the other end of the lower surface of the air blower 1. A recess 18 is provided to accommodate the spatula 2. This recess 18, which is also open on the front side of the cover 11, has a pair of upper and lower permanent magnets 35, as shown in FIGS. 4 and 5.
．． 35 is disposed on the back surface, and a pair of left and right locking protrusions 36, 36 are protruded, and furthermore, at the top of the recess 18, a 7-cut unit 81 of the micro switch 80 in the switch block 8 is provided. 3 out of 0 images located
7 is a magnetic mounting plate. As shown in FIG. 4, the nozzle head 2 attached to the tip of the hose 3 has a connection portion with the hose 3 inside a cylindrical housing 21 having a discharge port 23 formed on the side surface of the tip. The hose 3 is connected to the housing 21.
This is done via a rotating ring 24 which is rotatable relative to the rotating ring 24. Further, an opening/closing plate 26 is slidably disposed in a gap between the inner surface of the hashing 21 and the wind tunnel 22. As shown in FIGS. PttJ11 to FIG. 13, the opening/closing plate 26 integrally has click protrusions 28 with spring properties that click into a plurality of four parts 29 formed on the inner surface of the housing 21. The opening area of the discharge port 23, on which the lattice 25 is arranged, can be adjusted between the fully open state shown in FIG. 11(a) and the half-open state shown in FIG. 11(b). state, and the same figure (e
) It can be adjusted to three levels of 174 and 174 degrees. By adjusting the opening area of the discharge port 23, it is possible to reduce the amount of air and concentrate the area where the air hits. Furthermore, since the housing 21 and the wind tunnel 22 have a double h1 structure, the hand holding the rad 2 to the nozzle does not get hot. In addition, the joint between the wind tunnel 22 and the rotating ring 24,
The joint between the wind tunnel 22 and the grid 25 has a structure in which they fit into each other to prevent air from leaking. Furthermore, magnetic plates 31.31 are attached to the upper and lower positions of the surface of the nozzle rad 2 where the discharge port 23 is provided, and a pair of upper and lower magnetic plates 31.31 are also attached to the opposite surface. is installed. The magnetic plates 31, 31 located on the upper side are fixed to the housing 21 with screws 33, and the magnetic plate 31 located on the lower side is press-fitted using an undercut portion 34 formed in the housing 21, as shown in FIG. Fixed by Therefore, in this wall-mounted hair dryer, the rad 2 can be stored in the nozzle at the tip of the hose 3 led out from the blower 1 by fitting it into the recess 18 formed in the blower 1. When the seven-piece head 2 is fitted into the recess 18 in this way, as shown in FIGS.
1 is attracted, and the locking protrusion 36 locks onto the inner surface of the discharge port 23 from the opening of the lattice 25. Since the locking protrusion 36 has a tapered shape that is narrower on the tip side, it is easy to attach and detach the γ rod 2 to and from the nozzle. As described above, since the locking protrusion 3G is configured to lock on the inner surface of the discharge port 23, the Rad 2 can be hooked and locked to the nozzle even if there is no protrusion projecting from 7-2 to the nozzle. There is no need to provide a protrusion on the nozzle rad 2, and the nozzle rad 2 can be made thinner, and even when hooked onto the blower 1, it will not protrude from the wall. The amount can be kept small. In particular, in this embodiment, since the depth of the recess 18 from the rear surface of the blower 1 is increased, as is clear from FIG. It has become something that does not exist. In addition, the nozzle head 2 shown here has not only magnetic @ 31, 31 but also a pair of locking holes using the gap between the housing 21 and the wind tunnel 22 on the surface opposite to the discharge port 23. 3
9.39, by locking the locking protrusion 36 in the locking hole 39,
As shown in Figure 0, the nozzle can be hooked and locked onto the blower 1 by using both hands. You can also dry and set your hair. However, the operation of the blower 1 differs depending on the direction in which the nozzle hooks and locks the rad 2 onto the blower 1. That is, the microswitch 80 of the switch block 8 in which the seven cutout units 81 are located in the recess 18 is as follows.
It controls the power on/off, as shown in Figure 1 and #
When the nozzle radiator 2 is locked to the blower 1 in the state shown in Figure II4, the actuator 81 moves to the /X' head.
When pressed, the microswitch 80 switches as shown in FIG. 15(,), so the power is turned off.
When the power to the motor 40 and the heater block 5 is cut off and the nozzle head 2 is pulled out from the recess 18, the state shown in FIG.
), the microswitch 80 returns to its original state, and energization of the motor 40 and heater block 5 is started. On the other hand, as shown in FIGS. 9 and 10, when the nozzle rad 2 is locked to the blower 1 with the discharge port 23 exposed, the nozzle rad 2 is connected to the
Since the motor 40 and the heater block 5 are not pressed, the power supply to the motor 40 and the heater block 5 is maintained. Effect of the invention 1 As described above, in the present invention, since the inner surface of the discharge port of the nozzle head is used to hook and lock onto the blower, there is no need to provide a protrusion on the nozzle head, and the The nozzle head can be made thin, so even when the nozzle head is hooked onto an air blower and stored, the amount of protrusion from the wall is small and does not get in the way (also, the nozzle head is thin). (As a result, it is also easy to use.
