Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste treatment device suitable for treating waste odors such as used disposable diapers and kitchen garbage, and more particularly to a odor emitted from such wastes. The present invention relates to a filth treatment device for temporarily storing filth in a room while preventing the above.

[0002]

2. Description of the Related Art A conventional waste treatment device of interest to the present invention is described, for example, in Japanese Patent Laid-Open No. 1-226601. The waste treatment device described here uses a flexible tube in order to wrap the waste in a sealed state. This tube is drawn out from a cassette having a specific structure and twisted every time dirt is received, so that a malodor is prevented from being emitted to the outside. When the filth is sequentially accommodated in such a tube, the filth becomes a form like intestine-stuffed sausage and is discarded together with the tube.

[0003]

However, in the above-mentioned waste treatment apparatus, since the tube for enclosing the waste is fed out, a cassette having a specific structure must be used. There is a problem that the cost of the product is relatively high. In addition, such cassettes are often only available through specific channels of sale, and thus encounter difficulties with availability.

Therefore, an object of the present invention is to provide a waste treatment device which can be used with a consumable item which is very easily available.

[0005]

In the waste treatment device according to the present invention, a flexible bag is used to store the waste. In order to enable the use of such a flexible bag, the waste treatment device according to the present invention has the following configuration.

That is, the waste disposal device according to the present invention has a container having an opening at the top, a lid for closing the opening, and a flexible bag arranged in the container with the opening opened. A fixing mechanism that detachably fixes the peripheral edge portion of the container, and a diaphragm mechanism that is operated by an operation from outside the container so as to selectively squeeze a part of the bag from the periphery below the fixing mechanism.

[0007]

According to the present invention, a flexible bag for wrapping filth is arranged in the container, and the peripheral portion of the opening is detachably fixed by the fixing mechanism with the opening opened. And
The squeezing mechanism selectively squeezes a part of the bag from the surroundings under the fixing mechanism and the opening of the container is closed by the lid to prevent the odors from the waste contained in the bag from being emitted to the outside. To be

As described above, the filth disposal device according to the present invention is designed to squeeze a part of the bag by the squeezing mechanism below the fixing mechanism and keep the opening of the container closed by a lid, which is normally used in a room. Placed in. Then, when a new filth is put in the bag, it is operated in the following procedure. That is, first, the lid is opened, and in that state, the dirt is placed in the area surrounded by the peripheral portion of the opening of the bag fixed by the fixing mechanism. Next, the lid is closed, and in this state, the squeezing mechanism is first operated to open by an operation from outside the container. As a result, the dirt placed in the area surrounded by the peripheral portion of the opening of the bag falls into the bag.
Then, similarly, the squeezing mechanism is operated to close by an operation from the outside of the container. In this way, a series of operations during normal use of the waste treatment device is completed.

When the bag is filled with filth, first, the fixing of the peripheral portion of the opening of the bag by the fixing mechanism is released, then the opening of the bag is closed by wrapping it with an adhesive tape, and then the bag is closed.
The squeezing mechanism may be operated so as to be opened, and then the dirt may be taken out from the container together with the bag.

On the other hand, when a new bag is mounted in the container, the squeezing mechanism is opened, the bag is put in the container, and the opening of the bag is opened, while the peripheral portion of the bag is fixed by the fixing mechanism. Just fix it. When no dirt is stored in the bag, the squeezing mechanism does not have to be closed and may be left open.

[0011]

As described above, according to the present invention, it is possible to continue to use the waste treatment device only by using a flexible bag as a consumable item. For such a bag,
Since a bag made of polyethylene, polypropylene or the like, which is widely marketed as a garbage bag, can be used as it is, the cost of consumables can be extremely reduced, it is economical, and it is easily available.

In addition, since the squeezing mechanism can be operated from the outside of the container when the waste treatment device is in use, it is possible to operate the squeezing mechanism from the outside with the opening of the container closed with the lid. it can. Therefore, as described above, even when trying to put new dirt into the bag, the space inside the bag does not directly communicate with the outside of the container, so it is released from the dirt inside the bag. It is possible to minimize the leakage of the odor that is generated outside the container.

The fixing mechanism provided in the waste treatment device according to the present invention can be easily realized, for example, by combining a pair of ring-shaped members that sandwich the peripheral edge of the opening of the bag from both sides of the bag.

Further, the squeezing mechanism preferably comprises a plurality of vertical shafts arranged around the bag and rotatable about respective axes, and arms fixed to the vertical shafts and extending in the horizontal direction. , A rotation synchronizing means for synchronizing the rotations of the plurality of vertical shafts with each other, and a rotation driving means for rotating at least one vertical shaft in both the forward and reverse directions. The above-mentioned rotation synchronizing means preferably comprises a pulley fixed on each vertical shaft and an endless belt wound around the pulleys in sequence. With such a configuration of the diaphragm mechanism, the structure thereof can be simplified, and the space can be saved. As the rotation driving means provided in the diaphragm mechanism, a forward / reverse rotatable motor operated by a switch outside the container is used, or a handle fixed to at least one vertical shaft and pulled out of the container is used. be able to.

In the present invention, if the container has a double structure of an outer container and an inner container and a device for measuring the weight applied to the inner container is provided between the outer container and the inner container, the bag will be filth. It is easy to determine when the bag has been replaced, that is, when to replace the bag.

Further, in the present invention, when the deodorizer is provided on the surface facing the lower side of the lid, a foul odor that may leak from the bag even if the throttling mechanism is closed is further leaked from the container. It is possible to prevent it from coming out and leak from the bag when the squeezing mechanism is opened with the lid closed,
It is possible to prevent the malodor remaining in the container from leaking to the outside when the lid is opened.
