Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a braking device for a dehydrator, etc., which performs one braking by bringing a brake lining provided on a brake lever into pressure contact with a brake wheel in conjunction with opening and closing of a dehydrating lid. The purpose of this is to improve the braking effect by considering the shape of the brake lining, etc., and to enable smooth opening and closing of the dehydration lid.

Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

Figure 1 shows the structure of a general dehydrator. 1 is the dehydrator main body, a dehydrator receiver 2 is housed in the main body 1, and a clothes input port 3a is provided in the upper opening of the dehydrator receiver 2. A dehydration receiver cover 3 is attached.

Further, a dewatering cup 4 having a large number of dehydrating holes 4a is housed in the dehydrating cup 2, and a dehydrating shaft 5 is fastened to the dehydrating pot 4, and a shaft 9 of an electric motor 9 is supported by a spring 10 in a cushioning manner. ' is connected to the brake wheel 6 by a bolt 7 and a nut 8, and the driving force of an electric motor 9 is transmitted to the dewatering wheel 4, causing the dewatering wheel 4 to rotate.

11 is a brake mounting plate, and this brake mounting plate 11 is formed with a through hole 11a and a recess 11c, and the shaft 9' of the electric motor 9 is inserted into the through hole 11a, and the recess 1 is inserted into the through hole 11a.
It is fastened to the electric motor 9 via 1c with a screw.

Reference numeral 12 is a pin attached to the brake mounting plate 11, which rotatably supports a brake lever 13, and this brake lever 13 has a uniformly thick brake made of a hard material such as synthetic resin, leather, or asbestos. The lining 14 is fixed so as to be in contact with the brake wheel 6, and the tension brake spring 15 is engaged between the cut and raised part 11b of the brake mounting plate 11 and the brake lever 13, so that the brake lining 14 is pressed against the brake wheel 6. The end of the flexible tube 16 is held by a holder 17, etc., and one end of the ear 18 that slides inside the flexible tube 16 is a stopper. 19 is engaged with and held by the brake lever 13, and the other end is not shown, but is connected to the hinge bin 2.
The dehydration lid 22 is attached to a hinge 21 that is rotatably supported by the dehydration lid 22.

When the dehydration lid 22 is closed, the wire 18 is pulled against the spring force of the brake spring 15, and the pressure contact between the brake wheel 6 and the brake lining 14 is released.

When the dehydration lid 22 is opened, the wire 18 is loosened and pressed against the valve 6 of the brake spring 15, and the rotation of the dehydration lever 4 is braked.

However, in the above configuration, the center C1 of the bin 12
With respect to the line connecting □ and the center C6 of the brake wheel 6,
The brake spring 15 and the wire 18 are arranged in the long direction, and the outer end of the brake lining 14 is inclined by an angle θ with respect to the line connecting the center C12 of the bin 12 and the center C6 of the brake wheel 6. , the pressure contact force to the brake wheel 6 is the set load P15 of the brake spring 15.
In other words, a component force (P14) in the middle upper line direction (ca-p14) of the brake lining 14 acts. Therefore, if you want to improve the brake spring, you should increase the set load P15 of the brake spring 15. Accordingly, it was necessary to increase the closing force of the dehydration lid 22.

As a result, the dehydration lid could not be opened and closed smoothly, which caused problems in terms of usability.

The present invention was made in order to solve the above problems, and Fig. 3 shows the normal fluky lining 14 when it is pressed, and Fig. 4 shows the flag in front of it when braking is applied and dehydration is stopped. It is something.

That is, the brake mounting plate 11' is attached to the electric motor 9 with screws or the like, and one end of a brake lever 13' having a U-shaped cross section is rotatably supported on the brake mounting plate 11' by a pin 12'. .

Reference numeral 14' denotes a brake lining made of an elastic material such as rubber. This brake lining 14' has a thin wall at one end and a thick wall at the other end, and has a shape substantially the same as the arc of the brake wheel 6'.

In addition, this brake lining 14' has a thick part that is brought into contact with the brake wheel 6' as a rule of the bottle 12' of the brake lever 13', and a thin part that is placed between the center C12' of the bottle 12' and the center of the brake wheel 6'. It is fixed to the brake lever 13' so that there is a slight gap with the brake wheel 6' on the line connecting the brake lever 13'.

Reference numeral 15' designates a brake spring that is engaged with the cut-and-raised portion 11b' of the brake mounting plate 11' and the brake lever 13', and is constantly biased in the direction of pressing the brake lever 13' into contact with the brake wheel 6'. .

Reference numeral 16' denotes a flexible tube, and the end of the flexible tube 16' is held by a holder 17', etc., and one end of a wire 18' that slides inside the flexible tube 16' is connected to the brake lever 13' by a stopper 19'. Although the other end is not shown, it is configured to interlock with a dehydration lid 22 attached to a hinge 21 rotatably supported by a hinge bin 20 as shown in FIG.

When the dehydration lid 22 is closed, the wire 18' is pulled against the spring force of the brake spring 15', and the pressure between the brake wheel 6' and the brake lining 14' is released. , wire 18'
is loosened, and the brake lining 14' is pressed against the brake wheel 61 by the spring force of the brake spring 15', and braking is applied.

In the above configuration, when dehydrating the laundry, the laundry is first washed in a washing machine or the like, and then the dehydrating lid 22 is opened and the dehydrating laundry is put into the dehydrating container 4 through the input port 3a.Then, when the dehydrating lid 22 is closed, the 18' is pulled against the spring force of the brake spring 15', releasing the brake lining 14' from the brake wheel 6. This allows the dewatering lever 4 to rotate, and when the electric motor 9 is energized, the dewatering lever 4 starts rotating. It rotates in direction B, and the water contained in the laundry flows out from the dehydration hole 4a due to centrifugal force, is received in the dehydration receiver 2, and is discharged to the outside of the main body 1.

When the dehydration is completed, the power to the electric motor 9 is cut off, and when the dehydration lid 22 is opened, the wire 18' is loosened and the brake lining 14' is pressed against the brake wheel 6' by the spring force of the brake spring 15'. However, for safety reasons in use, it is necessary to immediately stop the rotation of the dehydrating cap 4 when the dehydrating lid 22 is opened.

Therefore, in one embodiment of the present invention, the brake lining 14' is made of an elastic material such as rubber, and has a thin wall at one end and a thick wall at the other end. ' and the thin side is in contact with the brake wheel 6', so that when the dehydration lid 22 is opened and the wire 18' is loosened, the thick part will be in contact with the brake wheel 6'. They begin to press against each other and are deformed in the rotational direction B due to frictional force, and this deformation further increases the frictional force, resulting in deformation into a substantially uniform thickness state as shown in FIG.

As a result, the curling of the brake lining 14' becomes larger, a greater braking force is obtained, and the braking time is also shortened.

Also, when the spinner wheel 4 stops rotating, the frictional force between the brake lining 14' and the brake wheel 6' disappears, so the compressed brake lining 14'
The thick part of the brake lining 14' returns to its original state as shown in FIG. 3, and the thin part of the brake lining 14' and the brake wheel 6'
There is no pressure contact with the

Therefore, the pressing force exerted by the brake spring 15' can also be reduced.

Also, at the moment when the rotation stops, it is completely rolled up as shown in FIG. 4, but after the rotation stops, the center C1□'
Since the brake lining 14' comes out of pressure contact with the brake wheel 6' as shown in FIG.
The closing force, that is, the force for separating the brake lever 13' from the brake wheel 6' can also be reduced.

As described above, according to the present invention, it is possible to obtain a braking device for a dehydrator, etc., which has a simple structure, is excellent in safety, and is easy to use, such as the ability to smoothly open and close the dehydrating lid.
