Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a dryer equipped with a blower fan and a heater and used for multiple purposes such as drying hair and body after bathing or swimming, drying hands after washing, or drying indoors.

[Conventional technology]

With this type of dryer, for example, when drying hair and when drying hands, there is a large difference in the height of the item to be dried, and even when drying hair, there are differences in height between people. There is a type of dryer in which the main body of the dryer can be moved up and down. Conventionally, in such dryers, the dryer body is connected to a weight that is approximately the same weight as the dryer body using a wire, and the wire is hung from a fixed pulley to suspend the dryer body and the weight. It can be moved easily up and down, and
The dryer body was designed to stop when the machine stopped, allowing the dryer body to be positioned at any desired height.

[Problem to be solved by the invention]

However, since it requires a weight that is almost the same as the weight of the dryer itself, the overall weight of the dryer is heavy, and the dryer itself is therefore large. However, unless you have a very large house, you may feel reluctant to install it. In addition, the power cord leading to the dryer body is exposed as a curled cord, which not only looks unsightly, but also often causes problems when the power cord gets caught. Additionally, although the dryer itself can be moved up and down, the direction of air blowing is fixed diagonally downward, making it inconvenient to use. The present invention was developed in view of these points, and aims to be small and lightweight, the height and direction can be easily changed depending on the dry area, and the power cord etc. can be easily changed. To provide a dryer that is not exposed and has a good appearance.

[Means to solve the problem]

The dryer according to the present invention includes: an upper frame containing a spring-type balancer; a lower frame containing an automatic power cord winding device; a hollow guide rod connecting the upper frame and the lower frame; It is connected to a wire led out from the balancer and inserted into the inside of the guide rod, and connected to a power cord led out from the automatic winding device and inserted into the inside of the guide rod, so that it can freely slide up and down on the guide rod. The first feature is that the dryer body is attached to the dryer body, and the dryer body is rotatable up and down,
The second feature is that the dryer is provided with a switching means that detects the downward state and enables a non-contact detection means disposed within the dryer main body to turn the dryer main body on and off. [Function] According to the first feature of the present invention, since the weight of the dryer main body is balanced by the spring force of the spring type balancer, it is possible to balance the weight of the dryer main body with a weight that is almost the same as the weight of the dryer main body. It is smaller and lighter than when used,
Furthermore, the wire connecting the balancer and the dryer body is inserted into the guide rod to which the dryer body is attached so that it can slide up and down, and the power cord is also led out from the automatic winding device and inserted into the guide rod. Therefore, these wires and power cords are not exposed.According to the second feature, the vertical orientation can be changed arbitrarily, and the hands can be easily adjusted after washing. When the dryer is placed in the downward position for drying, a non-contact detection means turns the dryer on and off, so there is no need to operate the switch with wet hands. [Embodiment] The present invention will be described in detail below based on the illustrated embodiment. This dryer is constructed of a dryer main body 1, a movable frame 2, and a frame 3. As shown in FIG. 5, the dryer main body 1 has a motor M and a pair of shafts respectively housed in the housing 10 formed as a pair of upper and lower parts.

The upper frame 31 incorporates a pair of spring-type balancers 35, 35, and the lower frame 32 incorporates an automatic power cord winding device 36. The movable frame 2 is attached to the guide rods 33 of the frame body 3 so as to be slidable up and down, and the dryer main body 1 is attached to the movable frame 2 so that it can be rotated up and down. a pair of pipe parts 21.21, a pair of handle bars 22, 22 installed between the upper and lower ends of both pipe parts 21.21, and a pair of handle bars 22, 22 installed between the vertical center parts of both pipe parts 21.21. It consists of a supporting plate 23,
As shown in FIG. 4, a linear ball bearing 24 consisting of a retainer and a large number of balls is disposed between the inner surface of the pipe portion 21 and the guide rod 33 for smooth vertical sliding. 25 in the figure is a linear ball bearing 24
Screw onto the end of the pipe section 21 with a nut for positioning and fixing. The end of the support plate 23 in the movable frame 2 enters the inside of the guide rod 33 through a slit 34 formed on the back side of the guide rod 33 and extending over the entire length in the vertical direction. is derived from a spring type balancer 35 disposed within 31 and a booley 37.
The tip of the wire 41 passed through is connected to the support plate 23 within the guide rod 33. In addition, a power cord 42 led out from an automatic winding device 36 arranged in the lower frame 32 and passed through a pulley 38 is passed from the inside of the guide rod 33 to the outside through a protective strip 26 fixed to the support plate 23. It is brought out as follows. The protective tube 26 is made of a wear-resistant material such as polyacetal resin. The dryer main body 1 includes a receiving plate 27 that protrudes from a supporting plate 23 of the movable frame 2 and has a circular opening.
By holding it between the side surface of the housing 10 and a plate 45 screwed to this side surface, it can be freely rotated up and down with respect to the movable frame 2, and the guide rod 33
The power cord 42 pulled out from the plate 4

Reference numeral 46 in FIG. 6 denotes a ball that is biased by a spring 47 whose one end is brought into contact with the receiving plate 27 and click-engages with a hole in a perforated steel plate 48 attached to the inner surface of the plate 45. Gives a click feeling at multiple locations when the machine body 1 moves up and down. The range of vertical rotation of the dryer body 1 is restricted by upper and lower handle bars 22,22. However, in this dryer, the upper frame 31 of the frame body 3
and the lower frame 32 are fixed to a wall and placed in a washroom or the like,
If you move the movable frame 2 up and down by holding the upper handle bar 22 or the lower handle 1ft22 of the movable frame 2, the dryer main body 1 will also move up and down, and at this time, the movable frame 2 and the dryer main body 1 The spring type balancer 35 to which the wire 4l is connected has a spring force equal to the sum of the weights of the movable frame 2 and the dryer main body 1, so that the dryer main body 1 can be easily moved up and down. It is something that can be done, and it also stops when it stops. In addition, 38.39 in Figure 1
are the upper and lower stoppers, respectively. In addition, in FIG. 1, the dryer main body 1 has the air outlet facing the front on the upper part of the frame 3.
, the dryer body l with the air outlet facing downward at the bottom of the frame 3.
, the dryer main body 1 attached to the frame 3
There is only one. In this dryer, not only the wire 4l, but also the dryer body l
Since the power cord 42 leading to the main body 1 of the dryer also passes through the guide rod 33 for guiding the vertical movement of the dryer body 1, the appearance is not deteriorated due to exposure of these parts, and the appearance is good. Since the power cord 42 is fed out and wound up by the spring-type automatic winding device 36 in response to the vertical movement of the dryer main body 1, the power cord 42 is not exposed, and there is no slack. The power cord 42 does not obstruct the vertical movement of the dryer main body 1. Furthermore, since the dryer main body 1 here not only moves up and down, but also can rotate up and down with respect to the movable frame 2, the convex portions 5 provided on both sides of the housing 10
The air blowing direction can be changed up or down by pinching and rotating the dryer body 1, and the dryer main body 1 can be set at a height according to the height of the user and the area to be dried. The user can freely select between blow-down blowing hot air from above (a in Figure 9) and blow-up blowing hot air diagonally upward (portion in Figure 9). ing. C in Figure 9 shows a state in which the dryer main body 1 is set at the lowest level and the air outlet is directed downward, that is, a state for drying hands. In this case, operate the switch with wet hands. In order to avoid this, the dryer body 1 is turned on and off by a non-contact switch S such as an infrared switch or an ultrasonic switch instead of being turned on and off manually. That is, a limit switch LS is attached to the lower surface side of the circuit board 17 in the dryer main body 1, and a protrusion 29 is provided protruding from the lower handle bar 22, so that when the dryer main body 1 is oriented downward, the protrusion 29 switches the limit switch LS through the hole 49 on the bottom side of the housing 10, so that the motor M and the heater H are turned on and off by the non-contact type switch S instead of the manual switch. Therefore, you can dry your hands by simply extending your hand below the air outlet, and there is no risk of electric shock when operating a switch with wet hands. Since the non-contact type switch S is turned on and off only when the dryer is turned towards the dryer, when the dryer body 1 is approached to dry hair etc., it is suddenly turned on and warm air is blown onto the face. There is no way that such a situation could arise. FIG. 8 shows a block circuit diagram. 60 in the figure is a power supply circuit;
61 is a control circuit mounted on the circuit board 17, 62 is a display and switch circuit equipped with a manual switch, 63 is a sensor circuit equipped with a non-contact switch S, 64 is a heater circuit, and 65 is a motor circuit.

【Effect of the invention】

As described above, in the present invention, in order to make the vertical movement of the dryer body easier, the dryer body is connected to a wire derived from a spring-type balancer, and the weight of the dryer body is balanced by the spring force of the balancer. In order to
It is smaller and lighter than when using a weight that is approximately the same weight as the dryer itself, so it can be used comfortably at home, and the wire allows the dryer body to slide up and down. The power cord leading to the dryer body is also led out from the automatic winding device placed in the lower frame and inserted into the guide rod, so these wires and power cords In this respect, it has a good appearance, and there is no chance of the power cord getting caught. According to the second feature, the vertical orientation can be changed arbitrarily, and when the hands are placed in a downward position, which is used for drying hands after washing,
In order to turn the dryer body on and off using non-contact detection means,
This eliminates the need to operate switches with wet hands.
In addition to improving operability, since the non-contact detection means will not turn on and off when the device is oriented in a different direction, there will be no discomfort caused by hot air suddenly being blown onto the face.
