Description

Safety device by opening and closing the door of food waste disposer

The present invention relates to a food waste disposal device, and in particular, in the food waste disposal device which mixes food waste and fermentation agent to fermentation and composting food waste and then processes it through agitation, blowing and heating, thereby ensuring user safety. The present invention relates to a door opening / closing monitoring device and a safety device of a food waste disposal device having a function of automatically stopping its operation when the door is opened during operation of the processor.

Each household or restaurant discharges a certain amount of food waste every day. The food waste may be used as livestock feed, or may be discarded after filtering only the water mixed with the food waste through a simple strainer.

The food waste disposal method increases the amount of garbage collection, and if the garbage is not thrown away frequently, it causes odors and pollutes the surrounding air, thus necessitating the use of a food waste disposal device.

1 shows an example of the food waste processor. The input door 12 for putting food waste and the discharge door 19 for taking out the processed food waste are formed outside the main body of the food waste processor, and the treatment tank 11 for processing the food waste inside the main body. And a deodorizing device for removing the odor generated during the food waste disposal process is installed.

Inside the treatment tank 11, the stirrer 16 is rotatably mounted to mix the fermenting agent and food waste introduced from the outside, and induces the fed food waste to be composted by fermentation. The stirrer 16 is rotated under the driving force by the reduction motor device 13 which is installed outside the processing tank 11 and is composed of a reduction gear train and a motor.

On the other hand, the fan heater device comprising a suction fan 14 for sucking outside air and a heater (not shown) installed to heat the air sucked by the suction fan 14 removes the moisture in the food waste by signaling the food. Reduce trash

At this time, the deodorizing device is installed on the upper portion of the food waste treatment machine, and removes the odor generated in the fermentation process of the food waste, as well as the odor in the steam generated by the operation of the fan heater. This water vapor is again condensed in a chiller (not shown) and discharged to the outside.

In addition, the deceleration motor device, the fan heater device, etc. connected to the stirrer 16 is connected to the control panel 18 to control the microcomputer, so that the operation of the food waste processor can be controlled by a predetermined program. The control panel 18 may control the operation of the food waste treatment apparatus sequentially according to a set time by having a timer, or by receiving an input of a temperature sensor installed in a drying container according to an internal temperature condition of the treatment tank 11. It is also possible to control the operation of the food processor.

When such a food waste treatment apparatus is used at home, operations such as opening the input door and injecting food waste or opening the discharge door and exchanging fermentation agent are performed. At this time, if the stirrer inside the processing tank is operated while the door is opened, it acts as a factor that may pose a danger to the user.

The present invention has been made in view of the above-mentioned problems, and an object thereof is to provide a food waste disposal device in which a stirring device or the like does not operate while the input door or the discharge door of the food waste disposal device is open.

EXAMPLE

The present invention will be described below with reference to the accompanying drawings, preferred embodiments.

Figure 2 is a block diagram showing an example of the circuit configuration of the food waste disposal system safety device according to the present invention.

This circuit is largely comprised of the microcomputer 100, the door switch detection unit 200, the door signal processing unit 300, the switching means 400, and the driving means 500.

The door switch detecting unit 200 is composed of a door opening and closing detection means (SW 3) provided in the input door 12 of the food waste processor and a door opening and closing detection means (SW 4) provided in the discharge door (19). The door switch may be formed by attaching a magnet to one side of the door and using a reed switch sensitive to a magnetic field on the opposite side thereof, or installing a micro switch operating according to opening and closing of the door according to opening and closing of the door. It is possible to form.

These door open / close switches are switches that are closed when each door is closed. In addition, since the two switches are connected in series, when both doors are closed, the door closing signal is input to the signal processing unit 300 and the microcomputer 100 which will be described later. The microcomputer 100 may process the door close signal and use it as a condition input for determining other operation conditions.

Reference numeral 300 is a signal processor that processes a door close signal. As an example of this signal processing unit, an operational amplifier IC 1 is used, a reference voltage obtained by dividing the power partial pressure is applied to an input side of one end thereof, and a close from the door open / close detection means SW 3 and SW 4 on the other input side. It is formed by inputting a signal.

The output from the signal processor 300 is applied to the driving means 500 via the switching means 400. Since the output power from the signal processor 300 is weak, the power for directly driving the driving means 500 of the food waste cannot be controlled.

Therefore, in the present invention, the triac TP 7 is used as an embodiment to control the power thereof. The output signal is applied to a gate G which is in charge of turning on and off the first electrode T1 and the second electrode T1 of the triac TP 7. Since the triac TP 7 can control the alternating current, the triac TP 7 is suitable for use in the control of an alternating current motor used as an example of the driving means 500 in the present invention.

In one embodiment of the present invention, the microcomputer 100 enables forward and reverse control of the driving means 500. In this forward and reverse control, the microcomputer 100 receives and processes the signals from the door open / close detection means SW 3 and SW 4 described above, and sets the rotation direction and rotation period according to the respective conditions.

Therefore, in the safety device of the present invention, by controlling the other terminal of the drive means 500 on and off in accordance with the door opening and closing times from the door opening and closing detection means (SW 3, SW 4), the drive means 500 Can be blocked.

Therefore, when the door open signal is detected from the door opening and closing detection means (SW 3, SW 4), the driving of the drive means 500 is stopped, the user is protected against the risk of injury due to the rotation of the stirring blade in the agitator do.

As described above, the safety device of the food waste disposal system of the present invention detects when the input door is opened for new food waste input, or when the discharge door is opened for discharge of the processed food, thereby stopping the operation of the stirring device. To achieve.

Thus, the food waste disposal device of the present invention improves the safety of its use, thereby providing an effect particularly suitable for home use.

While the invention has been shown and described with respect to certain preferred embodiments, it will be appreciated that the invention can be modified and modified in various ways without departing from the spirit or scope of the invention as set forth in the claims below. Those skilled in the art will readily know.
