DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage container which can be used in, for example, a toilet, a washroom, a kitchen, a hospital, etc. and into which filth can be put.

[0002]

2. Description of the Related Art Conventional garbage containers employ a container with a lid or a simple container without a lid. In such a garbage container, when an ashtray or the like is not installed near the garbage container, a cigarette or the like ignited by a poorly mannered person may be thrown into the garbage container.

Usually, garbage containers are often provided with filth storage bags such as vinyl and paper bags, and these filth storage bags are usually flammable because they are made of paper or vinyl.
When a lit butt or the like is thrown in, the butt may burn or may adhere to the container wall.

In addition, since combustibles such as paper waste are thrown into the trash container, the possibility of ignition is further increased when a butt is thrown in after the combustibles are thrown. .

In order to reduce the possibility of ignition, some trash containers have been proposed which can extinguish a cigarette butt when it is thrown. For example, a garbage container proposed in Japanese Utility Model Laid-Open No. 62-189302 will be described. A fire-extinguishing solution containing a surfactant is injected into a water-resistant bag that is broken by heat, and when fire occurs, the fire extinguishes the bag with heat. Spray the liquid and extinguish the fire automatically.
The trash container proposed in Japanese Utility Model Publication No. 8-3361 detects smoke by a smoke detector provided in the container and drives a fire extinguisher. The trash container proposed in Japanese Utility Model Laid-Open Publication No. 49-55966 is provided with a roller for crushing butts or the like of inserted cigarettes to extinguish a fire.
Furthermore, the trash container disclosed in Japanese Utility Model Publication No. 4-30162 has a fire extinguishing mechanism using a heat-sensitive device and a blocking plate made of a heat-resistant material.

[0006]

The above-mentioned conventional garbage container has a fire extinguisher when a lit cigarette butt or the like is thrown into the container. The fire was extinguished after the fire, and before the operation of each fire extinguishing device, although the inside was burned or melted by heat for a short time, damage remained. The residual heat of cigarette butts and the like can reach nearly 700 ° C., and even if the garbage container itself is made of a noncombustible resin, the damage received by the residual heat is great. In addition, when these damages are accumulated inside, an uneven surface is formed on the inner surface, so that even if the respective fire extinguishing devices try to operate, they cannot operate. Furthermore, even if it does not ignite luckily at that time, if it repeats, there is a possibility that it will eventually ignite, so it is easy to throw away hot bodies such as butts into garbage containers anyway. There was no problem.

Accordingly, the present invention is to solve such a conventional problem. The lid is automatically opened when a human body or the like approaches, and automatically closed when the human body or the like leaves after dust or the like is thrown in. If a hand holding a hot body such as a cigarette butt is lit, close the garbage container lid to prevent the hot body from being thrown in and prevent garbage from occurring. The purpose is to provide a container.

[0008]

In order to solve the above-mentioned problems, a trash container according to the present invention has a human body detecting means for detecting approach of a human body and the like, and a high temperature detecting means for detecting that a high temperature body such as a flame has approached. Means, and drive control means for driving a drive means in response to a detection signal from the human body etc. detection means or the high temperature detection means, wherein the drive control is performed while the human body etc. detection means detects the approach of a human body etc. Means for closing the lid by the drive control means when the lid is opened by the means and the high temperature detecting means detects a high temperature body such as a flame, wherein the detection signal of the human body etc. detecting means and the high temperature When both the detection signal of the detection means and the detection signal of the high temperature detection means are sent to the drive control means, the drive control means closes the lid by giving priority to the detection signal of the high temperature detection means.

With this, the lid is automatically opened when the human body or the like approaches, and automatically closed when the human body or the like leaves after the dust or the like is thrown in, and a hot body such as a lit cigarette butt is provided. When a hand or the like is approached, the lid of the garbage container is closed to prevent the introduction of a high-temperature body, thereby preventing a fire or the like from occurring.

The control means 50 keeps the closed state until the high temperature detecting means 7 does not detect the high temperature body, and can release the closed state when the high temperature detecting means 7 does not detect the high temperature body.

When the high temperature detecting means 7 detects a high temperature body such as a lit cigarette, for example, when the lid 3 is already open because somebody is already approaching the garbage container. When the detection signal from the high temperature detection means 7 reaches the control means 50, the control means 50 sets the high temperature detection means 7 in the same manner as in the case where the two detection signals are simultaneously inputted.
The driving means 4 is reversed by giving priority to the detection signal from the
Is closed. When the lid 3 is already closed when the high temperature detecting means 7 detects a high temperature body such as a cigarette, the control means 50 holds the closed state at least until the detection signal of the high temperature detecting means 7 disappears. in this way,
As long as the high temperature detecting means 7 detects a high temperature body such as a lit cigarette, the control means 50 keeps the lid 3 closed.
Hot bodies cannot be thrown into trash containers.

Next, the operation of the garbage container according to the first embodiment at the time of cleaning and inspection will be described. When an operator presses a switch 8 provided on the trash container main body 1, the control means 50 detects this and controls the drive control means 9 to drive the drive means 4 to stop the lid 3 at a fixed position, and Then, the fan 10 is stopped to stop the deodorizing means 5 from spraying the deodorant and the fragrance. This makes it easy for the operator to replace consumable parts and to perform work for collecting dust and the like.
