Abstract

PURPOSE: To extremely improve handling quality and to assure the cost effective execution of a garbage treatment by providing the machine with a control circuit which drives a pulverizing mechanism by the driving power of a motor to pulverize garbage and automatically stops a motor operating circuit upon judging of the end of the pulverizing. CONSTITUTION: The garbage is thrown in a treating chamber and a switch circuit 55 is turned on to operate a water pouring valve opening/closing circuit 54, by which a faucet, etc., are opened to continuously pour the city water. The motor operating circuit 53 is simultaneously operated to start the motor 10. The pulverizing mechanism is driven by the driving power of the motor 10 to grind the garbage. At this time, the load current of the motor 10 is made lower with the progression of the pulverizing treatment. The load current is taken via a current reading circuit 52 into a main body control circuit 60 and is compared with a regulated value. The motor operating circuit 53 and the water pouring valve opening/closing circuit 54 are turned off if the load current is below the regulated value. As a result, the handling quality is extremely improved and the cost effective garbage treatment is executed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage treating machine for crushing garbage (kitchen garbage) generated during cooking by a crushing mechanism attached to a sink.

[0002]

2. Description of the Related Art A conventional kitchen waste disposal machine has a rotary blade, which is rotatably mounted on the upper part of a rotary plate having a large number of discharge holes, and a fixed blade having a kerf on its outer periphery, which is fixed to the tip of the rotary blade. It is common to crush the garbage between the blades.

This crushed kitchen waste is discharged from the discharge port together with water (generally tap water) injected into the sink during operation.

Incidentally, as an apparatus of this kind, the actual construction of Shokai 62-83541
The examples are those described in Japanese Patent Publication.

[0005]

However, in this type of garbage processing machine, since the entrance of the garbage processing machine is partitioned by the rubber bellows, it is not possible to visually judge whether or not the processing of the garbage has been completed, and therefore the crushing noise is not detected. I had to open the and turn off the motor power switch manually. According to this, it is necessary to rely on the intuition of a person to turn the power supply “ON-OFF”, and it may be stopped before the end of the process, or may be operated for a while after the end of the process and then stopped. There is a difference.

Therefore, if the processing is stopped before the processing is finished, there is a problem that untreated kitchen waste remains in the processing chamber, causing an offensive odor, and if the motor is running for a while after the processing is finished, the motor becomes empty. In addition to operating, tap water that is injected in synchronism with it is wasted and is uneconomical in some cases.

The present invention has been made in view of the above-mentioned circumstances of the prior art, and its purpose is to detect the completion of crushing in the garbage treatment of the motor and automatically stop the motor and preferably water injection. The purpose is to provide a garbage disposal machine that makes it possible.

[0008]

A feature of the present invention is that a kitchen and a water input port, a crushing mechanism driven by a motor power, and a kitchen attached to a sink provided with a crushed kitchen and a water discharge port. In the processing machine, there is a garbage processing machine equipped with a control circuit that automatically stops the motor operating circuit when it judges the end of crushing.

[0009]

[Operation] In such a garbage disposal machine, the rotary blade mounted on the rotary plate directly connected to the motor is rotated with the tip of the rotary blade facing outward due to the centrifugal force of the weight of the rotary blade. The kitchen waste caught on is crushed by this rotary blade.

When the end of crushing of the garbage processing machine is detected, the power of the motor is automatically cut off.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 1 and FIG. 2 are overall structural views, in which 1 is a sink such as a sink, and a drain port 2 in the sink 1 has a flange 3, packing 4, flange rings 5, 5 ', and a mounting plate 6. , A screw 7 and the like, and is fixed by a connecting portion V of a garbage processing machine, and a crushing mechanism portion X is provided below the connecting portion V.
Is composed of the following parts.

That is, 8 is a casing and 9 is a processing chamber 2.
5, a drain casing 9 includes a drain casing 9, an garbage outlet 91 provided in the drain casing 9 and an outlet 92 for water 92, 10 is a motor, and 14 is fixed to a rotary shaft 12 of the motor 10 via a shaft sealing device 13. The rotary plate 14 has a large number of drain holes 20. Reference numeral 15 is a rotary blade that is swaged by a pin 16 and is rotatably attached to the rotary plate 14, and a rotary blade and a kerf 17 for crushing the material to be processed by rotation are the rotary plate 14
A fixed blade 18 fixed to the drain casing 9 is provided so as to surround the outer periphery of the motor 10, and a control board 50 is installed below the motor 10.

FIG. 3 is a block diagram of a circuit configuration of a control circuit of the kitchen garbage processing machine. The main body control circuit 60 driven by the power supply circuit 51 includes a motor current reading circuit 52 and a motor operating circuit 5.
3. The water injection valve opening / closing circuit 54 and the switch circuit 55 are controlled.

Next, the operation will be described with reference to FIG.
First, the kitchen waste is put into the processing chamber 25 before operation.

When the switch circuit 55 is turned "ON", the water injection valve opening / closing circuit 54 operates to open the water faucet or the like to continuously inject tap water, and the motor operating circuit 53 operates to start the motor 10. .

When the motor 10 rotates, the kitchen waste is crushed between the tip of the rotary blade 15 and the fixed blade 18, and the finely comminuted kitchen waste 91 is the discharge hole 20 of the rotary plate 14 and the fixed blade together with the injected water 92. The liquid is discharged from the discharge port 11 via the 18 cut grooves.

At this time, the load current of the motor 10 changes so as to decrease as the grinding process proceeds, as shown in FIG.

This load current is taken into the main body control circuit 60 via the current reading circuit 52, and a prescribed value (eg, FIG.
(Current at point P) in (1).

If it is less than the specified value, the motor driving circuit 5
3 and the water injection valve opening / closing circuit 54 are turned off.

As another method, a specified value (for example,
After the operation is continued for a certain time T ₁ from the time point (point Q in FIG. 4), it is turned “OFF”.

As yet another method, the current fetch of the motor 10 is the same as that of the above-mentioned embodiment, but the motor is changed by comparing the rate of change of current (for example, di in FIG. 4) with a prescribed rate of change. It is also possible to control the operation circuit 53 and the water injection valve opening / closing circuit 54.

As a result, the kitchen processing machine can be automatically stopped at the same time when the kitchen processing is completed.

Further, this load change is measured by the motor 1 as shown in FIG.
By detecting the change in the rotation speed of 0, control can be performed in the same way.

In the embodiment, both the motor and the water faucet are controlled, but it goes without saying that the water faucet may be manually operated to control only the motor.

[0026]

As described above, according to the present invention, the end of the garbage processing is automatically determined and the operation is stopped, so that the handleability is greatly improved and the economical garbage processing can be performed.
