[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filth disposal apparatus suitable for treating odor-emitting dirt such as used disposable diapers and garbage, and more particularly to an odor release from such filth. The present invention relates to a waste disposal apparatus for temporarily storing waste in a room while preventing waste.

[0002]

2. Description of the Related Art A conventional waste disposal apparatus which is of interest to the present invention is described in, for example, Japanese Patent Application Laid-Open No. Hei 1-2226601. The waste disposal apparatus described here uses a flexible tube to wrap the waste in a sealed state. The tube is fed from a cassette having a specific structure, and is twisted each time waste is received, thereby preventing a bad smell from being released to the outside. When filth is sequentially stored in such a tube, the filth takes the form of intestinal sausage and is discarded together with the tube.

[0003]

However, in the above-mentioned waste disposal apparatus, a cassette having a specific structure must be used in order to draw out a tube for wrapping the waste. There is a problem that the cost of goods is relatively high. Also, such cassettes are often only available through a particular sales channel, and thus encounter the problem of inaccessibility.

It is therefore an object of the present invention to provide a waste disposal apparatus which can be used with consumables which are extremely easily available.

[0005]

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

That is, in the waste disposal apparatus according to the present invention, there is provided a container having an upper opening, a lid for closing the opening, and a flexible bag disposed in the container with the opening thereof opened.

[0007]

According to the present invention, a flexible bag for wrapping filth is disposed in the container, and the peripheral portion of the opening is detachably fixed by the fixing mechanism with the opening opened. And
Since the stench from the contained waste in the bag is prevented emitted to the outside, below the fixing mechanism is closed by Rutotomoni down around either et part throttle mechanism of the bag, the opening of the container lid .

In the waste disposal apparatus according to the present invention, as described above, a part of the bag is squeezed by the squeezing mechanism below the fixing mechanism, and the opening of the container is closed by a lid. To be placed. Then, when newly putting waste into the bag, the operation is performed in the following procedure. That is, first, the lid is opened, and in this state, dirt is placed in a region surrounded by the periphery 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 periphery of the opening of the bag falls into the bag.
Thereafter, the squeezing mechanism is operated to be closed by an operation from outside the container. Thus, a series of operations during normal use of the waste disposal apparatus is completed.

When the bag is filled with dirt, first, the fixing of the peripheral portion of the opening of the bag by the fixing mechanism is released, and then the opening of the bag is closed by winding it with an adhesive tape or the like.
After operating the squeezing mechanism to open, the waste may be taken out of 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, and the peripheral portion is opened by the fixing mechanism. Just fix it. When no waste is stored in the bag, the squeezing mechanism does not need to be closed and may remain open.

[0011]

As described above, according to the present invention, the waste disposal apparatus can be continuously used only by using a flexible bag as a consumable. As such a bag,
Since a widely available bag made of polyethylene or polypropylene can be used as it is as a garbage bag, the cost of consumables can be extremely reduced, and it is economical and easily available.

Further, in the use state of the waste disposal apparatus, the squeezing mechanism can be operated by operation from outside the container. Therefore, it is possible to operate the squeezing mechanism from the outside while the opening of the container is closed with the lid. it can. Therefore, as described above, even when trying to put new filth into the bag, the space in the bag does not directly communicate with the outside of the container, so that the waste from the bag is released. It is possible to minimize the leakage of the bad odor to the outside of the container.

[0013] The fixing mechanism provided in the waste disposal apparatus according to the present invention can be easily realized by, for example, a combination of a pair of ring-shaped members sandwiching the peripheral edge of the opening of the bag from both sides of the bag.

The squeezing mechanism preferably includes a plurality of vertical shafts distributed around the bag and rotatable around respective axes, and arms fixed to the respective vertical shafts and extending horizontally. , A rotation synchronization means for synchronizing the rotations of the plurality of vertical shafts with each other, and a rotation drive means for rotating at least one vertical shaft in both forward and reverse directions. The above-mentioned rotation synchronizing means preferably includes a pulley fixed on each vertical shaft and an endless belt sequentially wound around the pulley. With such a configuration of the aperture mechanism, the structure can be simplified and the space can be saved. And, as the rotation driving means provided in the squeezing 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 if a device for measuring the weight applied to the inner container is provided between the outer container and the inner container, the bag becomes dirty. , That is, it is easy to determine the bag replacement time.

Further, in the present invention, if a deodorizer is provided on the surface facing the lower side of the lid, an odor which may leak from the bag even though the squeezing mechanism is closed further leaks from the container. While the lid is closed, it leaks out of the bag when the squeezing mechanism opens,
The odor remaining in the container can be prevented from leaking to the outside when the lid is opened.

The other is formed by a fixing ring 11 having an inverted U-shaped cross section. As can be seen, for example, by comparing FIGS. 1 and 4 with each other, the fixing ring 11 is rotatably attached to a bracket 12 provided on the outer container 5 via a pivot pin 13. Therefore, as shown in FIG. 4, the peripheral edge 8 of the opening of the bag 7 is
When the fixing ring 11 is fitted to the ring-shaped edge 10 as shown in FIG. 1 after being turned around, the peripheral portion 8 of the bag 7 is sandwiched between the ring-shaped edge 10 and the fixing ring 11. Is fixed.

The diaphragm mechanism 14 is operated so that the diaphragm around or we part of the bag 7 in the lower locking mechanism 9 is mainly disposed in the space between the outer container 5 and container (6). The squeezing mechanism 14 comprises a plurality of, in this example four, vertical shafts 15, 16, 17 and 18 rotatably arranged around each axis, distributed around the bag 7. These vertical shafts 15 to 18 are arranged between the outer container 5 and the inner container 6 and at the corners of the outer container 5 having a rectangular column shape. 8 and 9, illustration of the inner container 6 and the like is omitted.

Arms 19, 20, 21 and 22 extending in the horizontal direction are fixed to each of the vertical shafts 15 to 18. As can be seen from FIGS. 8 and 9, the arms 19 to 22 have different heights from each other so that their operations are not interfered with each other.
Each of the arms 19 to 22 has an arc-shaped portion having a circumferential angle of 90 degrees, and in the state shown in FIG. 9, these arc-shaped portions form one circle.

The plurality of vertical shafts 15 to 18 are rotated in synchronization with each other. Therefore, the vertical shaft 15-1
8 have pulleys 23, 24, 25 and 2 respectively.
6 is fixed, and the endless belt 27 is sequentially wound around these pulleys 23 to 26. These pulleys 23-2
The endless belt 6 and the endless belt 27 are arranged near the bottom surface of the outer container 5.

At least one of the vertical shafts 15 to 18 described above, for example, the vertical shaft 17
, It is rotated in both forward and reverse directions. The motor 28 is arranged, for example, in a base 29 formed on the bottom of the outer container 5. The above-described forward / reverse rotation of the motor 28
It is operated by a forward rotation switch 30 and a reverse rotation switch 31 provided outside, that is, on the upper surface of the lid 4 well shown in FIG. Each of the switches 30 and 31 is constituted by, for example, a push button switch. When the forward rotation switch 30 is pressed, the motor 28 is rotated forward by a predetermined rotation angle and then stopped. On the other hand, when the reverse switch 31 is pressed, the motor 28 is reversed by a predetermined rotation angle and then stopped.

The lid 4 is rotatably attached to the outer container 5 by a hinge 32. The lid 4 is provided with a concave portion 33 for hanging a finger, so that the lid 4 can be conveniently opened.

A deodorizer 34 is provided on a surface of the lid 4 facing downward. As the deodorizer 34, for example, a deodorizer such as activated carbon that adsorbs an odor, a deodorizer that decomposes an odor with a catalyst, and a deodorant that masks an odor with an aroma can be used.

The inner container 6 is held by the plurality of compression springs 35 with respect to the outer container 5. Then, a weight measuring device 36 for measuring the weight applied to the inner container 6 as a displacement of the inner container 6 with respect to the outer container 5 is arranged on the bottom surface of the outer container 5. The weight measured by the weight measuring device 36 is displayed by an indicator 37 provided on the upper surface of the lid 4 as shown in FIG. This indicator 3
Numeral 7 displays the weight in a bar graph, for example.

Such a waste disposal apparatus 1 is used as follows. First, at the start of use, the bag 7 is mounted. Therefore, as shown in FIG. 4, the lid 4 is opened, and the fixing ring 11 is set up. Further, in the aperture mechanism 14, as shown in FIG. 9, the arms 19 to 22 cooperate to form an open state forming one large circle. Then, the bag 7 is put into the inner container 6, and the peripheral edge 8 of the opening is folded around the ring-shaped edge 10. In this state, the fixing ring 11 is tilted down and fitted to the ring-shaped edge 10.

In the above state, the waste disposal apparatus 1 is ready for use. However, the lid 4 is preferably closed and the squeezing mechanism 1 is kept until the waste disposal becomes necessary.
4 is closed and waits. The normal rotation switch 30 is pressed to bring the aperture mechanism 14 into a closed state. As a result, the motor 20 is rotated forward, whereby the vertical shaft 17 is rotated forward. In response to this, the endless belt 27 moves in its longitudinal direction, as indicated by arrows in FIG. 9, and the other vertical shafts 15, 16 and 18 are rotated in synchronization with the vertical shaft 17 and the arm 19 to 22 are each rotated clockwise. Since each of the arms 19 to 22 has an arc-shaped portion, a part of the bag 7 located inside the arm is
It can be squeezed smoothly. The arms 19 to 22 finally have the form shown in FIG.

When waste to be treated by the waste treatment apparatus 1 is generated, the lid 4 is first opened, and the waste 38 is removed by the peripheral portion 8 of the opened opening of the bag 7 as shown in FIG. Placed in the enclosed area.

Next, more preferably, the lid 4 is closed as quickly as possible, and this time, the reverse switch 31 is pressed. As a result, the endless belt 27 moves in the longitudinal direction to rotate the vertical shafts 15 to 18 synchronously and reversely, and the arms 19 to 22 respectively move as shown by arrows in FIG. Rotated counterclockwise. As a result of this rotation, the arm 19
To 22 realize an open state as shown in FIG. Therefore, the filth 38 falls into the bag 7 as shown in FIG. Next, the forward rotation switch 30 is pressed again, whereby the arms 19 to 22 are closed as shown in FIG. This state is shown in FIG. In the state shown in FIG. 3, the apparatus waits until the next waste is generated. In the state of FIG. 3, the deodorizer 34 removes odor remaining or leaking below the lid 4.

When the operation method as described above is repeated and the bag 7 is filled with the waste 38, the state can be known by the indicator 37. And filth 3
When the user wants to discard 8 together with the bag 7, as shown in FIG. 5, the lid 4 is first opened, and then the fixing ring 11 is brought up. Thereby, the peripheral part 8 of the opening of the bag 7 is detached from the ring-shaped edge part 10, and the vicinity of the opening of the bag 7 is
For example, it is bound by winding an adhesive tape 39. Instead of the adhesive tape 39, a string or the like may be used, or the peripheral edge portion 8 of the opening of the bag 7 may be tied. Further, if a heat sealing device is provided, heat sealing may be performed. Thereafter, the reverse switch 31 is pressed to bring the arms 19 to 22 into the state shown in FIG. 9, and the waste 38 is taken out of the container 3 together with the bag 7 as shown in FIG.

Subsequently, as described above, a new bag 7 is mounted in the container 3 and is ready for the next use.

In the description of the operation of the waste disposal apparatus 1 described above, the operator operates the normal rotation switch 30 and the reverse rotation switch 31 to rotate the motor 28 in a desired direction according to each situation. For example, a microcomputer or the like may be incorporated so that the rotation of the motor 28 is controlled in conjunction with the opening / closing operation of the lid 4.

On the other hand, in the waste disposal apparatus 1, a configuration that does not require a power source at all may be adopted in consideration of safety. An example of such a configuration is shown in FIGS.
This will be described with reference to FIG.
