Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a braking device for a kitchen waste disposal machine that pulverizes kitchen waste from home kitchens, etc., and its purpose is to shorten the inertial rotation time after the equipment stops operating.

In conventional kitchen waste processing machines, after the kitchen waste has been pulverized,
Even if the motor is stopped, it continues to rotate for about 5 seconds due to the inertia of the rotating body.

In general, if a person working in the kitchen were to put their hand into the grinding chamber after the motor had stopped operating, their hand would come into contact with the rotating part in about 3 seconds, so there is a risk of injury due to the above-mentioned inertial rotation. It had a sexual nature. The present invention aims to reduce the above-mentioned conventional risks, and the present invention will be explained below based on drawings showing embodiments thereof.

In FIGS. 1 and 2, 1 is a water tank such as a sink, 2 is a kitchen waste inlet attached to the water tank 1, and a main body 4 of the kitchen waste disposal machine is fixed to the lower part via a tightening rubber 3. Reference numeral 5 denotes a crushing chamber provided inside the main body 4, and a fixed blade 6 is provided in the opening □ at the lower end of the crushing chamber 5.

Reference numeral 7 denotes a rotary blade that rotates opposite to the inner surface of the fixed blade 6, and the rotation of a motor 8 is transmitted to this rotary blade 7 via a reduction gear device 9 and a rotating shaft 10.

Reference numeral 11 denotes a spinner fixed to a rotating shaft 101. This spinner 11 has an inverted conical shape and has a large number of slits 12 on its outer circumferential surface.

Reference numeral 13 denotes a kitchen waste discharge port provided in a part of the main body 4 close to the outer circumference of the upper end of the spinner 11, through which kitchen waste discharged from the spinner 11 is discharged.

Reference numeral 14 denotes a drain port provided at the bottom of the main body 4, which is connected to the sewer via a trap 15.

Reference numeral 16 denotes a rotating arm that is always in contact with the outer periphery 17 of the cylindrical portion inside the main body 4. The rotating arm 16 is made of an elastic body and rotates simultaneously with the spinner 11.

A fixed arm 18 is fixed to a part of the main body 4 and disposed close to the inner circumferential surface of the spinner 11, and is used to scrape up kitchen waste.

A kitchen waste storage box 19 is detachably connected to the kitchen waste discharge port 13 of the main body 4 and stores the kitchen waste discharged from the kitchen waste discharge port 13.

20' is a plastic bag that is detachably attached to a kitchen waste storage box 19, and the upper opening □ of this plastic bag 20 is attached to the kitchen waste outlet 13.

The operation in the above configuration will be explained.

First, kitchen waste is introduced into the crushing chamber 5 through the kitchen waste input port 2. Then, by driving the motor 8, the rotary blade 7, the spinner 11,
The rotary arm 16 rotates at the same time, the kitchen waste is crushed by the fixed blade 6 and the rotary blade 7, and the spinner 1 is crushed by centrifugal force.
Moisture is separated from the kitchen waste pressed against 1, and the water is drained into the sewer through drainage row 4. The dehydrated kitchen waste is scraped up by the fixed arm 18 and stored in the plastic bag 20 in the kitchen waste storage box 19 through the kitchen waste discharge port 13. Next, the operation for reducing the inertial rotation time after the operation of the kitchen waste disposal machine is stopped will be explained.

First, immediately after motor 8 starts operating, rotary arm 1
6 rotates while being in elastic contact with the outer periphery 17 of the cylindrical part inside the main body 4, and when the rotation of the motor 8 exceeds a certain rotation, the rotating arm 16 is bent outward due to centrifugal force and separated from the outer periphery 17 of the cylindrical part. Rotate in the same position. When the crushing is completed and the operation of the motor 8 is stopped, the centrifugal force acting on the rotary arm 16 decreases, and when the rotational speed of the rotary arm 16 due to inertia falls below a certain level, the rotary arm 16 returns to its original state due to its own elastic force. Then, it contacts the outer periphery 17 of the cylindrical portion inside the main body 4 again. Due to the braking effect obtained by this operation, the inertial rotation time of the equipment is extremely shortened. As described above, according to the present invention, when the centrifugal force acting on the rotary arm decreases after the motor stops operating, and the rotational speed of the rotary arm due to inertia 1 becomes below a certain level, the rotary arm is activated by its own elastic force. Since it returns and makes elastic contact with the outer periphery of the main body to perform a braking action, the inertia rotation time after the equipment stops operating can be significantly shortened compared to conventional equipment, and as a result, the work after stopping the equipment is greatly reduced. In addition to ensuring safety, the inertia rotation time can be set as desired by adjusting the pressing force using elasticity or by combining the materials of the contact parts.Furthermore, the braking device of the present invention can be applied to other rotating equipment, etc. It has excellent features.
