Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a low-speed rotary clothes dryer for quickly drying laundry and the like.

<Prior art> Conventional rotary clothes dryers using electric motors are dangerous because the clothes drying rod continues to rotate even when a child gets caught in the clothes drying rod and excessive external force is applied to the clothes drying rod. However, there was also the drawback that the transmission part between the electric motor and the clothes rack could break down.

<Purpose> Therefore, the present invention aims to make the clothes drying rod automatically stop when an excessive external force is applied to it, making it safe, and making the transmission part between the electric motor and the clothes drying rod less likely to malfunction. Another object of the present invention is to provide a rotary clothes dryer that maintains its friction transmission function even after long-term use.

<Means for solving the problem> The means for solving the problem according to the present invention are shown in Figs. 1 to 4.
As shown in the figure, it is equipped with a column 1 with a stand, a concentrator 2 attached to the column 1, and a clothes rod 3 attached to the concentrator 2, and a part of the column 1 houses an electric motor and the motor. A transmission outer peripheral surface 6a is installed on the interlocking portion 5b of the rotating shaft 5 of the electric motor.
is fitted into the interlocking hole 6b of the truncated cone-shaped friction transmission body 6, and the friction transmission body 6 and the focusing plate 2 are in a state where friction transmission is possible so as to rotate together, and the transmission is made to the center of the conical plate 2. A friction transmission hole 2a is formed in which the inner peripheral surface 2a is in the shape of a truncated cone, and the transmission hole 2a and the transmission outer peripheral surface 6a are removably fitted to each other so that a constant value (the laundry hung on the laundry rod 3 is The following frictional transmission is possible (rotating force), and even if the electric motor rotates when a force exceeding this certain value is applied to the clothesline 3 and the stacking board 2, the clothesline 3 and the stacking board 2 The second side is configured to stop.

<Function> In the above-mentioned means for solving the problem, since the laundry dries quickly when fresh, dry air is supplied around it, the low-speed electric motor is driven to speed up drying. Then, the rotating shaft 5 of the electric motor
The rotational force of the friction transmission body 6 is transmitted to the friction transmission body 6 through the interlocking hole 6b, and the rotational force of the friction transmission body 6 is transmitted to the friction transmission body 6 through the surface friction between the transmission outer peripheral surface 6a and the transmission hole 2a of the convergence plate 2. 2, the laundry is transmitted to the clothes drying rod 3, and the laundry rotates at a low speed.

If a child or the like gets caught on the clothes rod 3 during this rotation, the resistance will be between the transmission outer peripheral surface 6a and the transmission hole 2.
Since it exceeds the frictional transmission force that exists between a and a, the focusing disk 2 stops rotating even if the frictional transmission body 6 rotates, so it is safe and there is no failure of the transmission part.

<Example> An example of the present invention will be described below with reference to FIGS. 1 to 6. Fig. 1 is a partially cutaway side view of the main part of a clothes dryer in an embodiment of the present invention, Fig. 2 is a cross-sectional plan view of the main part, Fig. 3 is a plan view, and Fig. 4 is a cross-sectional plan view of the main part.
The figure is also a side view.

As shown in the figure, the clothes dryer of the present invention includes a support 1 with a four-legged stand formed of a circular pipe,
A plastic concentrator 2 attached to the pillar 1
and a plurality of clothes drying rods 3 which are rotatable in the vertical direction (Y direction) and are attached radially to the concentrating board 2.

An electric motor with a speed reducer is installed in a cylindrical motor housing 4 with a lid attached to the upper end of the pillar 1, and the electric motor is connected to a power cord 6 (or a battery), and the rotation shaft 5 of the electric motor D
A D-shaped interlocking hole 6 of a plastic friction transmission body 6 whose transmission outer peripheral surface 6a is a truncated cone is attached to the interlocking portion 5b having a shaped cross section.
b are fitted, and the friction transmission body 6 and the focusing plate 2 are frictionally transmitted so as to rotate together, and a friction transmission hole 2a having a truncated conical inner peripheral surface 2a is formed in the center of the focusing plate 2. has been done. The transmission hole 2a and the transmission outer circumferential surface 6a are capable of frictional transmission below a certain value (the force that rotates the laundry hung on the clothesline 3 at low speed), and the force exceeding this certain value is applied to the clothesline. Even if the electric motor rotates when acting on the clothesline rod 3 and the bundling board 2 side, the washing rod 3 and the bundling board 2 side are configured to stop. Reference numeral 7 indicates electrical wiring within the pillar 1, and reference numeral 8 indicates a detachable power cord.

Next, to explain how it works, laundry dries faster when fresh, dry air is supplied around it.
When drying is needed quickly, the low-speed electric motor is activated. Then, the rotational force of the rotating shaft 5 of the electric motor is transmitted to the friction transmission body 6 via the D-shaped interlocking hole 6b, and the transmission outer peripheral surface 6a and the transmission hole 2 of the focusing plate 2
The rotational force of the friction transmission body 6 is transmitted to the collecting plate 2, that is, the clothes drying rod 3, through the surface friction between the washing machine and the washing machine, and the laundry rotates at a low speed.

If a child or the like gets caught on the clothes rod 3 during this rotation, the resistance will be between the transmission outer peripheral surface 6a and the transmission hole 2.
Since it exceeds the frictional transmission force existing between a and a, the focusing disk 2 stops rotating even if the frictional transmission body 6 rotates, so it is safe and there is no failure of the transmission part.

Although not shown, a frictional resistance increasing material may be interposed between the transmission outer peripheral surface 6a and the transmission hole 2a and fixed to the transmission outer peripheral surface 6a or the transmission hole 2a.

It should be noted that the present invention is not limited to the above embodiments, and it goes without saying that many modifications and changes can be made to the above embodiments within the scope of the present invention.

<Effects of the invention> As is clear from the above explanation, according to the invention, laundry dries quickly when fresh, dry air is supplied around it, so when drying is desired, the low-speed electric motor is driven. Then, the rotational force of the rotating shaft of the electric motor is transmitted to the friction transmission body through the interlocking hole, and the friction transmission body is transmitted through the surface friction between the truncated conical transmission outer peripheral surface and the truncated conical transmission hole of the focusing plate. The rotational force is transmitted to the collection plate, ie, the clothesline, and the laundry rotates at a low speed.

Therefore, in the present invention, when a child or the like gets caught in the clothesline while it is rotating, the resistance is
This exceeds the frictional transmission force existing between the truncated conical transmission outer circumferential surface and the truncated conical transmission hole, so even if the friction transmission body rotates, the focusing disk stops rotating, making it safe and the structure of the transmission part simple. There are almost no failures, and even if the truncated conical transmission outer peripheral surface and the truncated conical transmission hole become worn out due to long-term use, since they are truncated conical, the degree of engagement between them will only deepen.
There is an excellent effect when the function of friction transmission is maintained.
