Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a garbage storage device installed in a kitchen or the like.

2. Description of the Related Art Cooking waste and the like are generally produced in kitchens, etc., and it is desired to store them in a manner that does not spoil the aesthetic appearance of the kitchen, etc., or emit bad odors.

FIG. 1 shows an example of a conventional garbage storage device. This garbage storage device has a structure in which a garbage container 2 is installed inside a kitchen furniture 1. Specifically, the garbage container 2 is fixed inside a door 3. When the door 3 is opened, an operating string 4, one end of which is fixed inside the kitchen furniture 1, pulls open the lid 5 of the garbage container 2, allowing garbage to be thrown in.

FIG. 2 shows an example of a conventional garbage storage device that prevents the odor from entering the room.
The garbage thrown in from the garbage input port 8 provided on the indoor side of the room is stored in the garbage container 10 in the garbage storage device 7 through the duct 9, and the odor generated from the garbage is forced out from the exhaust pipe 12 by the fan 11. We are trying to discharge it to the outside. Note that 13 in the figure is a sink, and 14 is a lid that can be attached to and detached from the garbage inlet 8.

Problems to be Solved by the Invention However, the former type has the advantage that it does not spoil the aesthetic appearance of the kitchen because the garbage container 2 is housed inside the kitchen furniture 1, but when the door 3 is opened, Since the lid 5 of the garbage container 2 is opened, there is a problem in that the odor of the garbage flows into the kitchen room.

Although this device is effective in not spoiling the aesthetics of the kitchen and preventing the odor of garbage from occurring indoors, it requires a long exhaust pipe 12 to be erected outdoors, which impairs the aesthetics of the outside of the house. This is undesirable because the odor will flow to neighboring houses.

The present invention has been made in consideration of the above-mentioned conventional problems, and an object of the present invention is to provide a garbage storage device that can effectively exhaust odors without impairing the aesthetic appearance of indoor or outdoor spaces.

Means for Solving the Problems The present invention includes a garbage storage section, a drain pipe that is attached to a house and has a back odor prevention section upstream, one end of which is connected to the garbage storage section, and the other end of which is connected to the back odor prevention section of the drain pipe. The exhaust pipe is connected to the downstream side of the exhaust pipe, and a fan device for forcibly suctioning air from the dust storage section and guiding it to the ventilation pipe, and the exhaust pipe is provided with a backflow prevention valve.

Function The garbage storage device of the present invention forcibly exhausts the odor inside the garbage container through the drain pipe, so that the aesthetic appearance of the kitchen is not spoiled, and the odor is not emitted into the indoor or outdoor atmosphere, resulting in a sanitary environment. The environment is not damaged. Furthermore, since the exhaust pipe is provided with a backflow prevention valve, even if backflow water occurs from the sewer, the backflow prevention valve prevents the backflow to the fan device, thereby protecting the fan device from backflow water.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 3, 4, and 5.

In the figure, 15 is a sink installed in a room such as a kitchen, and the water in the water tank 16 is drained into an outdoor sewer 19 via a drain trap 17 and a drain pipe 18 connected to the bottom of the water tank 16. It's summery. The sink 15 has a cabinet configuration, and has a door 20 on its front side, and behind the door 20 is provided a garbage container 22 whose lower part is pivoted with a hinge 21 and whose upper part is open so that it can be opened forward. There is. A fan device 23 is installed inside the sink 15 and above the waste container 22. This fan device 23 has a fan 24 as its main component,
The intake port 25 is provided corresponding to the upper opening of the waste container 22. Further, a push-type switch 26 for operating the fan 24 is provided on the front surface of the sink 15, and is controlled to be pressed by the upper edge of the door 20. In other words, when the door 20 is opened, the push switch 26 is pressed. When the door 20 is released, it is turned on, and when the door 20 is closed, it is pressed and turned off. Note that when the garbage container 22 is opened forward, the upper opening of the garbage container 22 does not come out completely, and the rear part of the opening is connected to the air intake port 2.
5 (see Figure 4). An exhaust pipe 27 is led out from the fan device 23, and this exhaust pipe 27 is connected to a drain pipe 18 on the downstream side of the drain trap 17 in the drainage system of the aquarium 16.
A check valve 28 is provided in the drain pipe 18.

The check valve 28 is constructed as shown in FIG. 5, that is, a float ball valve 30 is provided in a valve casing 29, a valve seat 31 is provided in the upper part of the valve casing 29, and a stopper 3 is provided in the lower part of the valve casing 29.
2 has been established.

In addition, when storing garbage in the garbage container 22, a polyethylene garbage bag (not shown) is attached to the garbage container 22 in advance.

In the above configuration, the water in the water tank 16 is drained into the sewer 19 through the drain trap 17 and the drain pipe 18. When storing garbage, first open the door 20.
At this time, the switch 26 is turned on, the fan device 23 is operated, and the odor emitted from the garbage in the garbage container 22 is sucked in and does not flow into the room. Next, the garbage container 22 is tilted forward and garbage is thrown into it. Even in this state, the rear part of the upper opening of the garbage container 22 faces the intake port 25, and most of the garbage odor is sucked in and does not flow into the room. The inhaled odor then passes through the drain pipe 18 to the sewer line 1.
Exhausted at 9. In the above-mentioned exhaust, the exhaust pipe 27 is connected to the downstream side of the drain trap 17, and the water sealing function of the drain trap removes the odor from the water tank 17.
Does not leak to the sides. Furthermore, since the odor is discharged into the sewer 19, it is not dissipated into the outdoor atmosphere and pollutes the atmosphere. When garbage storage is completed, garbage storage container 2
2 and closes the door 20, the switch 26 is turned off and the operation of the fan device 23 is stopped.

If the lower part of the drain pipe 18 is clogged with something and the waste water enters the exhaust pipe 27 direction, or the sewer pipe 19
When sewage flows backward, the exhaust pipe 27 is provided with a backflow prevention valve 28, so that the wastewater or sewage does not enter the fan device 23, ensuring electrical safety.

In this way, in the garbage storage device of the embodiment described above, the garbage container 22 is housed within the cabinet of the sink 15, so that the exterior appearance of the room is not spoiled. In particular, the odor generated from the garbage in the garbage storage container is forcibly discharged to the sewer using the drain pipe 18 by the fan device 23, so not only will no odor be emitted indoors when dumping garbage, but it can also be used outdoors. Odors are not released into the atmosphere and do not disturb neighbors. Furthermore, since the exhaust pipe 18 is connected to the downstream side of the drainage trap 17, no odor will be emitted to the water tank 16 side, and even if drainage or sewage flows back, it will not enter the fan device 23, making it electrically safe. It is. Such a sink 15 is always equipped with a drain pipe 18, which is advantageous in terms of construction since it is used for exhaust.

In this embodiment, the switch 26 is controlled by opening and closing the door 20.
The switch 26 may be manually operated.

Also, when the door 20 is closed, the fan device 2
3 is not working, and the inside of the cabinet is filled with odor generated from the garbage in the garbage container 22, and there is some leakage from the seams of the cabinet plate, but according to experiments, the leaked odor is The odor is hardly felt and there is no problem in practical use. FIG. 6 shows another example of the non-return valve 28 according to the present invention, which is provided with a valve plate 30' which is elastically biased upward and closed in place of the float ball valve. In response to exhaust from upstream, it is pushed downward to allow said exhaust,
This prevents backflow from downstream.

In addition, in each of the above embodiments, the drain pipe is a sink drain pipe, but it may be a bathtub, washroom, flush toilet, or other drain pipe, and therefore, the drain pipe in the present invention is not limited to that related to a sink. .

Effects of the Invention As is clear from the above embodiments, the garbage storage device of the present invention forcibly exhausts the odor inside the garbage container through the drain pipe, and does not impair the beauty of the kitchen, etc. In addition, it does not emit odors into the indoor or outdoor atmosphere, and does not impair the sanitary environment.The exhaust pipe is equipped with a backflow prevention valve, which prevents water from flowing back into the sewer, and the fan device is designed to prevent water from draining, etc. It is of great value as it cannot be damaged by
