Description

Technology Field

[0001] The present invention relates to a smart food waste bin for comfortable food disposal, and more specifically, to a smart food waste bin for comfortable food disposal that allows a user to dispose of food conveniently and comfortably without getting their hands wet. Background Technology

[0002] Generally, users experience inconvenience when disposing of food waste in standard trash cans located near apartments or restaurants. When placing food waste into a plastic bag for disposal, water drips out during the process.

[0003] People usually leave the house for appointments, work, or studies, and modern individuals typically dispose of food while out. However, if food gets on their hands during this process and there is no place nearby to wash them, they are forced to return home with dirty hands, making it difficult to handle food comfortably. Users attending an appointment have two options to avoid this unpleasantness: going to the meeting place with dirty hands and washing them nearby, or returning home to wash their hands before leaving. Many users typically find this situation unpleasant.

[0013] FIG. 1 is a basic operational block diagram of the present invention. Figure 2 is a photograph of the present invention FIG. 3 is an application image of the present invention Specific details for implementing the invention

[0014] The present invention relates to a smart food waste bin for comfortable food disposal, comprising a food waste bin having a sensor installed inside and composed of a body (10) and a lid (20);

[0015] It is composed of a controller; characterized by being able to know how much waste is filled inside the food waste bin without opening the lid.

[0016] In addition, the sensor is characterized by being installed on the lid.

[0017] In addition, the sensor is characterized as being an ultrasonic sensor as a distance sensing sensor.

[0018] The present invention will be described in detail with reference to the attached drawings as follows.

[0019] The present invention detects user movement using an ultrasonic sensor, transmits the amount of space in the food waste bin to an administrator terminal, and shows the availability of the food waste bin to a user terminal via an LED or display.

[0020] The present invention utilizes an ultrasonic sensor to transmit a signal to a control unit of a controller when a person stands in front of it within a certain distance. The control unit receives the signal and drives an electric stepper motor installed on a hinge between the trash can body and the lid to automatically open the trash can lid. Therefore, it is possible to know how much trash is inside the food waste bin without opening the lid. Furthermore, as the trash fills up, a plastic bag full of food is flipped over by gravity on a pole inside the trash can, and the plastic bag is sucked in by a suction motor driven by the controller or transferred to an external trash can by a conveyor belt to be disposed of.

[0021] The present invention is configured such that an ultrasonic sensor, which is a distance sensor, is installed on the upper inner part of the lid, allowing one to know how much waste is contained inside the food waste bin without opening the lid. Specifically, the control unit displays the distance value received from the sensor on a display, or the distance can be determined without opening the lid. The controller is installed in the body or the lid.

[0022] Therefore, ultrasonic sensor 1 is used to check if the distance from the user is 20 cm or less, and if it is 20 cm or less, the lid of the food waste bin opens. After processing the food waste, if the distance from the user increases, the control unit of the controller drives the door opening / closing electric stepper motor to close it automatically. When the bin is full of food, a separate plastic bag suction motor is driven to automatically suck up plastic bags and dispose of them in an external bin. Additionally, the value of the distance measured from the lid via the ultrasonic sensor is displayed on a display formed on the body, and can also be transmitted to smart devices such as a manager terminal or a smartphone serving as a user terminal to be displayed on the smartphone touch screen. By communicating via a Bluetooth module, the capacity to hold food waste can be monitored in real time. FIG. 2 is a photograph of the present invention, in which the trash can on the left is the main food waste bin, the trash can on the right is the plastic bag collection bin, and the suction motor is mounted on the right trash can.

[0023] The controller is equipped with a communication module and communicates via Bluetooth. The controller consists of an input unit for receiving sensor signals, an LED or display output unit, a transceiver unit, a comparison unit that compares the measured distance based on the sensor signal with a set value, a storage unit for storing data, and a control unit. Meanwhile, a hazardous gas detection sensor is installed inside the trash can. If hazardous gas is generated by toxic substances in food waste, the sensor transmits this information to the control unit. If the control unit detects a hazardous gas stored in the storage unit, it does not open or close the lid even if a user approaches within a certain distance; instead, an alarm mechanism activates a speaker to provide an audible alarm regarding the hazardous gas generation. Furthermore, since hazardous gases are generated through the fermentation or decomposition of food waste, causing the height inside the body to rise, if the height rises beyond a certain distance within a certain time after insertion, the control unit determines that a large amount of hazardous gases, such as ammonia, are being generated instantaneously, posing a risk of explosion near open flames such as kitchen appliances, and similarly triggers an alarm signal. In addition, by installing a conventional weight sensor at the bottom, if the height rises beyond a certain distance within a certain time after insertion and the weight changes suddenly at the same time, the control unit determines that there is a risk of explosion and can generate an alarm signal.

[0024] Therefore, the present invention has the significant effect of enabling the user to conveniently and comfortably process food without getting water on their hands.
