The crushed raw garbage 12 is packed in a collecting bag 11 provided at the raw garbage discharge port 19, and a temperature sensor for detecting the temperature inside the condenser 5 and the drying oven 6. 22 and the temperature sensor 27 and the water level sensor 21 in the water storage tank 10 are input to the control unit 20, and all the driving units such as the rotating basket 26, the crusher 9 and the heater 23 associated with the operation of the garbage treatment device are heated. The configuration is controlled by the control unit 20.

Next, the operation of the food waste processing apparatus configured as described above will be described with reference to the flowcharts of FIGS. 3 and 4. In addition, in FIG. 3 and FIG. 4, and are operatively connected, and are also operatively connected.

[0012] A user throws in raw garbage from an input port 1 connected to a drain port of a sink sink. At this time, the opening 2 is open, and the stirring blade 25 is positioned horizontally so as not to be entangled when the raw dust is charged. The thrown food waste is stored in the rotating basket 26 and drained at the mesh portion of the rotating basket 26, and the water flows into the water storage tank 10 through the crushing device 9 and the water storage drainage port 8.

The water used for cooking in the sink is
Water tank 1 through a drying furnace 6, a crusher 9, and a drainage port 8 for storing water
The water flows to 0, is stored, is used as cooling water for the condenser 5, and is discharged to the outside from the drain port 15 via the drain pipe 18 when the water amount is large and full. Then, the garbage is collected and the user selects the operation start or the timer operation. When the timer operation is selected, the operation start time is input, and the operation waits until the start time.

When the operation start is selected or when the timer operation start time comes, the opening 2 is closed, and when it is completely closed, the drying treatment operation is started, and at the same time when the operation is started, the water level in the water tank 10 is detected, Even if it is not the full amount, the circulation pump 16 is operated to draw up the water accumulated in the water tank 10, and the water is radiated from the jet part 17 to the heat radiating part of the condenser 5 for cooling.

Next, the heater 23 and the circulation fan 24 are operated to dry the raw garbage in the rotating basket 26, and periodically rotate the stirring blades 25 so that the raw garbage is evenly dried. The temperature in the drying furnace 6 is detected by the temperature sensor 26, and the temperature of the condenser 5 is detected by the temperature sensor 22 and is continuously input to the control unit 20.

Since the temperature in the drying furnace 6 rises as the drying operation progresses, the controller 20 controls the temperature suitable for drying (A ° C.).
When the temperature becomes, the heater 23 is turned off, and when the temperature is lower than A ° C., the heater 23 is turned on repeatedly.
Further, the temperature of the condenser 5 is such that the water contained in the garbage is evaporated to generate steam in the drying furnace 6, and as the drying operation progresses, the amount of steam increases and the temperature of the condenser 5 rises to be condensed. At the beginning, when the drying operation further progresses, the condensed steam becomes constant, and the temperature of the condenser 5 does not rise and becomes constant. As the drying operation progresses, the water content of the garbage decreases, the temperature of the condenser 5 decreases, and when the moisture of the garbage completely disappears, no steam is generated and the temperature of the condenser 5 becomes constant for a certain time. (See Figure 5).

As a result, the end of the drying process operation is judged, and the heater 23 is turned off. Then, the temperature inside the drying furnace 6 that has been heated to a high temperature is lowered, and there is no problem even if the dried garbage is discharged (it is lowered to around room temperature and put in the collection bag 11 without any problem. When the temperature is reached, the circulation fan 24 and the circulation fan 16 are stopped, the drainage device 13 is operated, the drainage valve 14 is opened, and the cooling water in the water tank 10 is discharged from the drainage port 15.

Next, the drive device 3 is operated to crush the dried raw garbage, and the rotary basket 26 is rotated 180 °, whereby the raw garbage in the rotary basket 26 is dropped to the pulverizer 9 and the pulverizer 9 is crushed. Is operated, the garbage is crushed one after another,
It is packed in a collection bag 11 provided at the garbage discharge port 19.

At this time, the drive current of the motor provided in the drive device 3 for rotationally driving the screw feeder in the crushing device 9 is detected, and the current value is determined because there is a load on the motor when crushing the garbage. It is high, and the current value decreases when there is no garbage and the load disappears. Therefore, when the current value decreases and becomes constant, the control unit 20 determines that there is no garbage, and stops the crushing device 9 to end the crushing process. (See FIG. 6). If the temperature inside the drying furnace 6 has dropped to room temperature, the drainage device 13 is turned off and the drainage valve 1
4 is closed and the opening 2 is opened to return to the operation standby state.

It should be noted that, despite the fact that the cooling water stored in the water storage tank 10 is full and a large amount of water is flowing in, or the opening 2 is closed during operation, When a sink is used and water flows from the drain port, when it is guided to the water storage tank 10 through the drain pipe 4, it overflows from the drain pipe 18 and is discharged to the outside from the drain port 15.

By these driving operations, it is possible to treat the garbage without soiling the hands.

[0022]

Since the raw garbage treating apparatus of the present invention has the above-mentioned structure, the invention of the raw garbage treating apparatus according to the first aspect of the present invention generates steam when the raw garbage drying operation is continued,
Although it is condensed into water by the condenser, it is installed in the lower part of the sink and is close to a closed state, so the air permeability is poor, and the ambient temperature of the main body may rise as the operation progresses, and the condensation efficiency may deteriorate, so the condenser By using the cooling method of cooling the heat radiating part, it is possible to condense the water vapor without lowering the condensing efficiency, and it is expected that the condenser is downsized and the cost is reduced accordingly. In addition, downsizing of the condenser can be expected to reduce the size of the food waste processing apparatus body and reduce costs.

In the invention of the garbage disposal according to claim 2, the water for cooling the heat radiating portion is newly used from the tap water by using the water once used for cooking before starting the operation. In addition, the condenser can be miniaturized and cost reduction can be expected without lowering the condensation efficiency.

Further, according to the invention of the garbage treatment apparatus in claim 3, even if a small amount of cooling water in the water tank is circulated by a pump or the like and sprayed on the heat radiating portion of the condenser, steam is generated without lowering the condensation efficiency. Can be condensed.

Further, the invention of the garbage treatment device according to claim 4 has a function of determining the end of the drying treatment operation by detecting the temperature of the condenser during the drying treatment operation and obtaining the change rate thereof. In comparison with the garbage management device that is controlled by time management, there is no waste of operating time due to excessive heating and insufficient drying of garbage due to insufficient heating.Therefore, reduction in power consumption due to reduced operating time and insufficient drying Dissatisfaction of the user due to can be eliminated.
