Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an improvement in a hanging dryer equipped with a plurality of arms for hanging laundry, in which the arms can be rotated.

<Prior art> A hanging dryer shaped like an umbrella frame, with multiple arms attached to the tip of a shaft that can be opened and closed freely, and laundry can be hung on the arms, has a simple structure and is inexpensive. There are few restrictions on where it can be used, and it can be used indoors on rainy days, and it can be closed and stored when not in use, making it easy to use and making it widely popular. Further, in order to enhance the drying effect, a device in which the arm portion is slowly rotated by a motor has been proposed (see, for example, Japanese Utility Model Publication No. 49-133030, Japanese Utility Model Publication No. 55-6555, etc.).

<Problems to be solved by the invention> The products described in each of the above publications have the possibility that if a foreign object hits the rotating arm or the laundry and is lifted, it will easily fall and stain the wet laundry. However, the former has a structure in which an unreasonable force is applied to the drive unit if the rotation is stopped due to contact with a foreign object, and both pose practical problems.

The present invention has been devised to address these problems and to provide a hanging rotary dryer that has a simple structure and is free from the above problems.

<Means for solving the problem> In order to achieve the above object, the hanging rotary dryer of the present invention has a plurality of arms that can be opened and closed at the lower end of the suspended main shaft, and a A hanging dryer for hanging laundry is equipped with a rotary drive unit that rotates the main shaft, a clutch plate at the lower end of the main shaft, and an arm mounting member shaped like an upside-down bottomed cylinder at the bottom. The main shaft is passed through and placed on the clutch plate, and a plurality of arms are attached to this arm attachment member.

<Function> Since the arm rotates, the air that hits the laundry hung on the arm is constantly flowing, reducing the time required for drying. Furthermore, since the arm mounting member is simply placed on the clutch plate, the arm mounting member easily slips or is lifted, which may cause excessive force to be applied to the rotational drive unit.
There is no possibility that the whole dryer will fall after being lifted up to the main shaft, and the arm mounting member will not come off from the main shaft.

<Example> Next, an illustrated embodiment will be described.

In FIG. 1, 1 is a support member shaped like a hook, 2 is a motor attached to the lower end of the support member 1, and 3 is a main shaft connected to the output shaft 2a of the motor 2 via a universal joint 4. A clutch plate 6 is fixed to the tip. The motor 2 has a built-in speed reducer with a large speed reduction ratio, and the output shaft 2a is configured to rotate at a slow speed of, for example, one rotation every 5 seconds. Reference numeral 5 denotes an arm attachment member in the shape of a bottomed cylinder turned upside down.
is held at the tip of the main shaft 3 with the
A flange portion 5b is provided at the lower end of the arm attachment member 5, and more than ten arms 7 for hanging laundry are attached to the upper surface of the flange portion 5b so as to be rotatable radially and vertically. The arm 7 is supported by the flange portion 5b and is kept in a horizontal state when opened. 8 is a clip provided at the tip of the arm 7, and 9 is a power cord for the motor 2.

The present embodiment has the above-mentioned configuration, and when used, the support member 1 is hung by hooking it on a suitable fixed object 10 such as a crossbar provided on a pillar, and the arm 7 is opened horizontally. This is laundry 11
, connect the power cord 9 to an outlet, and operate the motor 2. As a result, the main shaft 3 rotates slowly at a predetermined speed, and the laundry 11 is dried more quickly than when the main shaft 3 is fixed. Furthermore, when not in use, the arm 7 can be closed and put away as shown by the chain line in the figure, and no space is required for storage.

Further, the main shaft 3 passes through the arm mounting member 5, and since the main shaft 3 does not protrude from the lower part of the arm mounting member 5 because it is simply placed on the clutch plate 6, the arm 7 or the laundry 11 may be exposed to something. If the motor 2 gets stuck, it will not slip at this part and no excessive force will be applied to the motor 2. For example, even if an upward force is applied to the arm mounting member 5 due to a person's head touching it, the arm mounting member 5 will only be lifted, and the arm mounting member 5 may come off the main shaft 3 or reach the main shaft 3. There is no possibility that the support member 1 will come off the fixed object 10 due to being lifted and the whole dryer will fall.

The universal joint 4 is for smoothly transmitting rotation to the main shaft 3. For example, even if the support member 1 is attached to the fixed object 10 at a slight incline, the main shaft 3 will not be suspended vertically. It is now in a stable state and can be rotated without any problems.

FIG. 2 is a comparative example of the rotary dryer of the present invention and a non-rotating fixed dryer, where A shows a rotary dryer and B shows a fixed dryer. As samples, five towels each having a total dry weight of 280 g were soaked with water to give a total weight of 800 g, and the experiment was conducted indoors at a humidity of 55 to 62% and a temperature of 32 to 32.5°C. The rotation speed of the device of the present invention is 11.4 rpm. As is clear from the figure, the time required for almost complete drying is 4
It takes less than 55% of the time required for a fixed type.

Note that since the rotational speed of the output shaft 2a is slow, the motor 2 only needs to have a small output, and instead of the motor, a mechanical rotation drive unit such as a spring type can also be used. It can be used in places without power.

<Effects of the Invention> As is clear from the description of the above embodiments, the hanging rotary dryer of the present invention rotates the suspended main shaft and presses the clutch plate provided at the lower end of the main shaft. Multiple arms are attached to an arm attachment member that is shaped like an upside-down cylinder with a bottom placed on the machine.Even if it is used indoors without wind, it will still hold the laundry in the same way as when it is exposed to wind. It can be dried quickly, and when it comes into contact with a foreign object, no strain is applied to the rotary drive unit or the entire dryer or arm attachment member falls. Therefore, it is easy to create a highly practical hanging rotary dryer that has a simple structure, is easy to handle, does not take up much storage space, and does not cause wet laundry to get dirty when dropped. can be obtained.
