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 unwound from a cassette having a specific structure, twisted every time dirt is received, and 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, a tube having a specific structure has to be used in order to feed the tube enclosing the waste. Therefore, when using this waste treatment device,
There is a problem that the cost of consumables 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 treatment apparatus according to the present invention has a housing having an opening at the top, a lid for opening and closing the opening, and a flexible bag arranged in the housing with the opening open. A fixing mechanism that detachably fixes the peripheral portion of the opening and a closing mechanism that is operated below the fixing mechanism to selectively close a part of the bag are provided.

The above-described closing mechanism includes a pair of sandwiching members that are movably held in the lateral direction on both sides of the bag, and a pair of rotatably held on both sides of the bag.
A pair of drive shafts, a pair of pinions that are rotated integrally with each of the pair of drive shafts, and a rack having teeth that mesh with each pinion to synchronously cause the respective rotations of the pair of pinions. , An operating member operated from outside the housing to apply an external driving force to any part on the motion transmission path from the rack to each drive shaft, and a pair of sandwiching members close to the bag. And a bendable connecting link for transmitting the rotation of each drive shaft to each sandwiching member so as to operate in synchronization with each other so as to be separated from each other.

[0008]

According to the present invention, a flexible bag for wrapping dirt is arranged in the housing. In that state, the peripheral portion of the opening of the bag is fixed by the fixing mechanism, and the opening of the bag is opened. Then, in order to prevent the bad smell from the waste contained in the bag from being emitted to the outside, the opening of the housing is closed by the lid, and at the position below the fixing mechanism, a pair of sandwiching members provided for the closing mechanism. The bag is closed by sandwiching the bag from both sides.

As described above, the waste treatment apparatus according to the present invention is usually placed indoors with the closing mechanism closing a part of the bag and the housing opening closed with the lid. . 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 that state, the operation member operable from the outside of the housing is operated. As a result, the pair of drive shafts and the pair of pinions operate while being linked by the rack.
The rotation of the pair of drive shafts is applied to the pair of pinching members via the connecting link, and the pair of pinching members is operated to separate from the bag. As a result, the bag is opened and the dirt, which had been placed in the area surrounded by the perimeter of the bag opening as described above, falls into the bag. Then the drive shaft is rotated in the opposite direction,
The pair of pinching members are moved closer to the bag to bring the bag back closed. 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, and then the opening of the bag is closed by wrapping it with an adhesive tape, and then the bag is closed.
The pair of sandwiching members may be moved in a direction away from the bag, and then the dirt may be taken out from the housing together with the bag.

On the other hand, when a new bag is mounted in the housing, the pair of sandwiching members are separated from each other, the bag is inserted into the housing, and the opening of the bag is opened, while the peripheral portion of the bag is opened. May be fixed by a fixing mechanism.

[0013]

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, and it is economical and easily available.

Further, when the waste treatment device is in use, the pair of sandwiching members included in the closing mechanism can be operated by an operation given to the operating member from outside the housing, so that the opening of the housing is closed by the lid. The pair of sandwiching members can be operated even when they are held. 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 housing, and therefore is discharged from the dirt inside the bag. It is possible to minimize the leakage of a bad smell to the outside of the housing.

Further, in the waste treatment apparatus according to the present invention, the pair of sandwiching members that directly act on the bag so as to selectively close the bag can be brought close to each other so as to come into contact with each other. The bag closed by the member can maintain a good sealed state.

Further, since the bending member is used to transmit the rotation of the drive shaft to each of the sandwiching members, the space required for operating the sandwiching members can be relatively small, and therefore the sewage disposal apparatus is large. Will not be invited.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 to 7 are for explaining a waste treatment device 1 according to an embodiment of the present invention. Here, FIG. 1 to FIG. 4 are all front views showing a vertical cross section of the waste treatment device 1, but the cut surface shown in FIG. 1 and FIG. 2 and the cut surface shown in FIG. 3 and FIG. Are different from each other. The former cut surface is located closer to the front side of the waste treatment device 1 than the latter cut surface. 1 and 2 show different states, and the state shown in FIG. 3 corresponds to the state shown in FIG. 1, and the state shown in FIG. 4 corresponds to the state shown in FIG. .

As shown in FIGS. 3 and 4, the waste treatment device 1 includes a housing 3 having an opening 2 on the upper side.
The housing 3 has a container shape as a whole and can be separated into an upper portion 4 and a lower portion 5. The upper part 4 and the lower part 5 are combined as airtightly as possible. Further, the opening 2 is openably and closably closed by a lid 7 rotatably supported by a shaft 6.

In the housing 3, a flexible bag 8 which is widely sold as a garbage bag is arranged. The bag 8 is shown in FIG.
Also, as shown in FIG. 4, with the opening opened, the peripheral edge portion 9 of the opening is detachably fixed by the fixing mechanism 10. The fixing mechanism 10 includes the opening 2 in this embodiment.
A combination of a ring-shaped edge portion 11 formed on the periphery of the ring-shaped member and a ring-shaped member 12 detachably fitted to the ring-shaped edge portion 11 is provided. Therefore, the peripheral portion 9 of the opening of the bag 8
When the ring-shaped member 12 is placed on the ring-shaped edge portion 11 and then the ring-shaped member 12 is fitted to the outer periphery of the ring-shaped edge portion 11, the peripheral edge portion 9 becomes the ring-shaped edge portion 11 and the ring-shaped member 12.
It is sandwiched and fixed by.

Below the fixing mechanism 10 there is arranged a closing mechanism 13 which is operated to selectively close a part of the bag 8. As shown in FIG. 3, the closing mechanism 13 includes a pair of sandwiching members 14 and 15 for sandwiching the bag 8 from both sides and closing the bag 8. These sandwiching members 14 and 1
As shown in FIG. 4, the 5 can be separated from the bag 8, that is, can be separated from each other. The main part of the mechanism for imparting motion to the sandwiching members 14 and 15 is shown in FIGS. 1 and 2. In addition, in FIG.
And 15 are shown in plan view.

The clamping members 14 and 15 and the mechanism for imparting movement to the clamping members 14 and 15 are held by a frame 16 which is best shown in FIGS. As shown in FIG. 5, the frames 16 are located on both sides of the sandwiching members 14 and 15, respectively. These frames 16 are mounted along the inner surface of the upper portion 4 of the housing 3. In addition, each frame 1
Since the shape of 6 and its associated structure are substantially symmetrical to each other, the following description will be given in connection with one frame 16 shown in FIGS. 1 and 2, and to avoid redundant description, FIG. Then, the same reference numerals are given to corresponding portions.

The sandwiching members 14 and 15 each have an elongated rod shape, and the guide pin 1 is provided at both ends thereof.
7 and 18 are provided. The guide pins 17 and 18 are received in guide slots 19 and 20 provided in the frame 16 so as to extend laterally. Thereby, the sandwiching members 14 and 15
Are held movably in the lateral direction on both sides of the bag 8.

A pair of drive shafts 21 and 22 are rotatably held by the frame 16 on both sides of the bag 8. Each end of each of the drive shafts 21 and 22 penetrates the frame 16, and on the outside of the frame 16, a pair of pinions 23 and 24 respectively,
It is mounted so as to rotate integrally with the drive shafts 21 and 22.

Since the rotations of the pair of pinions 23 and 24 are synchronously generated, the rack 25
Are arranged outside the frame 16. In rack 25,
Guide slots 26 and 27 are provided in which guide pins 28 and 29 provided on the frame 16 are received, respectively. As a result, the rack 25 can be translated in the lateral direction within a predetermined range. The rack 25 is provided with teeth 30 that mesh with the pinion 23 from above and teeth 31 that mesh with the pinion 24 from below. Therefore, the drive shaft 21 and the pinion 23 and the drive shaft 22
The pinion 24 and the pinion 24 are interlocked with each other via a rack 25 so as to rotate in opposite directions. A compression spring 32 is preferably arranged between the rack 25 and the frame 16, and the rack 25 is preferably biased so as to always move to the right as shown in FIG.

When an external driving force is applied to any part on the motion transmission path from the rack 25 to each of the drive shafts 21 and 22, these elements are operated in synchronization. In order to give this driving force, the operation lever 33 is fixed to one end of the drive shaft 21 in this embodiment. As shown in FIG. 6, the operating lever 33 is located outside the housing 3 and can be operated from outside the housing 3.

As an operating member for applying the driving force as described above, instead of the operating lever 33, for example,
An operation knob fixed to the rack 25 may be adopted. The operation knob is exposed to the outside of the housing 3, and the rack 2 can be moved by moving the operation knob in the lateral direction.
5 is moved laterally.

According to the rotation of the pair of drive shafts 21 and 22 in the opposite directions, the pair of sandwiching members 14 and 15 approach and separate from the bag 8 in synchronization with each other. In order to achieve such an operation, the drive shafts 21 and 22 and the sandwiching members 14 and 15 are connected by bendable connecting links 34 and 35, respectively. The connecting links 34 and 35 are more specifically the drive shaft 2
Arms 36 and 37 extending integrally from 1 and 22;
Arms 38 and 39 integrally extending from the pinching members 14 and 15, and arms 36 and 37 and arm 3
Pins 40 and 41 for rotatably connecting 8 and 39 are provided, respectively.

In such a structure, the closing mechanism 13 operates as follows. First, in FIGS. 1 and 3, a state in which a part of the bag 8 is closed is realized. In this state,
The pair of pinching members 14 and 15 are close to each other,
The bag 8 is closed by sandwiching the bag 8 from both sides of the bag 8.

On the other hand, in the state shown in FIGS. 2 and 4,
The bag 8 is open. To change from the state shown in FIGS. 1 and 3 to the state shown in FIGS. 2 and 4, the operation lever 33 is rotated counterclockwise.
As a result, the following operations simultaneously proceed.

First, the drive shaft 21 rotates counterclockwise in FIGS. 1 to 4, and the connecting link 34 bends in an inverted V shape as shown in FIG. As a result, the sandwiching member 14 is guided by the elongated guide hole 19 and moves leftward.

On the other hand, when the drive shaft 21 rotates counterclockwise, the pinion 23 rotates in the same direction and the rack 25 moves leftward. At this time, the compression spring 32
It is shrunk against its elasticity. The leftward movement of the rack 25 causes the pinion 24 to rotate in the clockwise direction, and accordingly, the drive shaft 22 to rotate in the clockwise direction. As a result, the connecting link 35 is bent in an inverted V shape as shown in FIG. 4, and the sandwiching member 15 is moved rightward along the elongated guide hole 20.

In this manner, the pair of sandwiching members 14 and 15 are separated from the bag 8 and the bag 8 can be opened.

In this embodiment, the operation lever 33 described above is used.
When the force for rotating the gear in the counterclockwise direction is removed, the compression spring 32 acts to automatically return to the state shown in FIGS. 1 and 3. That is, the elastic force of the compression spring 32 moves the rack 25 to the right, thereby rotating the pinion 23 clockwise and the pinion 24 counterclockwise. Therefore, the drive shaft 21 is rotated clockwise, the connecting link 34 is linearly extended, and the sandwiching member 14 moves to the right. On the other hand, drive shaft 2
2 rotates counterclockwise, the link 35 extends linearly, and the pinching member 15 moves to the right. As a result, the bag 8 is again sandwiched by the pair of sandwiching members 14 and 15 from both sides.

As described above, when the rack 25 is biased so as to always move to the right, the bag 8 may be inadvertently left in an open state as shown in FIGS. 2 and 3. As well as disappearing, it is possible to more reliably maintain the closed state of the bag 8. The compression spring 23 can be replaced by an element capable of performing an equivalent function, and such an element is not on the rack 25 but on the motion transmission path from the rack 25 to each of the pinching members 14 and 15. It can also be provided in connection with either part. If the advantage provided by such a compression spring 32 is not desired, the operation of the closing mechanism 13 may be achieved by rotating the operating lever 33, both without reciprocating the compression spring 32.

FIG. 7 is an enlarged sectional view showing a pair of sandwiching members 14 and 15 which are in close proximity to each other. As shown in FIG. 7, the sandwiching members 14 and 15 include
Preferably, concave-convex surfaces 42 and 53 that are fitted to each other are formed. Thereby, the pair of sandwiching members 14
When 15 and 15 sandwich the bag 8, this makes it possible to improve the tightness of the closed bag 8. In order to further enhance the hermeticity, it is effective to configure at least the surfaces of the sandwiching members 14 and 15 with an elastic body such as rubber.

Next, a method of using the waste treatment device 1 will be described. First, at the start of use, the bag 8 is mounted in the housing 3. Therefore, the lid 7 is opened and the operation lever 33 is operated to
As shown in FIG. 4, the pair of pinching members 14 and 15 are brought apart from each other, and the bag 8 is extended to reach into the lower portion 5 of the housing 3. On the other hand, the peripheral edge portion 9 of the opening of the bag 8 is positioned above the ring-shaped edge portion 11, and the operation of the operation lever 33 is released at this stage. Thereby, the pair of sandwiching members 14 and 15
Close to each other and close the middle part of the bag 8. Next, bag 8
A peripheral edge portion 9 of the bag 8 is placed above the ring-shaped edge portion 11, the ring-shaped member 12 is fitted therein, and the peripheral edge portion 9 of the bag 8 is fixed.

In the above-mentioned state, the waste treatment apparatus 1 is in a usable state, and the lid 7 is preferably closed until the necessity of treating the waste arises.

When a waste material to be treated by the waste treatment apparatus 1 is produced, the lid 7 is first opened, and the waste material 44 is moved by the peripheral edge portion 9 of the opened opening of the bag 8 as shown in FIG. It is placed in the enclosed area. The lid 7 is then closed as quickly as possible, after which the operating lever 33
Is rotated. This causes the pair of pinching members 14 and 15 to be separated from each other, as shown in FIGS.
Falls towards the bottom of the. In this way, immediately after dropping the dirt 44, the operation on the operation lever 33 is released. As a result, as shown in FIGS. 1 and 3, the bag 8 is closed again, and the process waits until the next dirt is generated.

When the bag 8 is filled with the dirt 44 by repeating the above-mentioned operation procedure, the dirt 44
Are discarded together with the bag 8. In this case, first the lid 7 is opened and then the ring-shaped member 12 is removed. Then, the peripheral edge portion 9 of the opening of the bag 8 is bound by, for example, winding an adhesive tape. After that, the operation lever 33
The bag 8 is taken out from the housing 3 while rotating the and holding the pair of sandwiching members 14 and 15 in a state of being separated from each other. At this time, the upper part 4 of the housing 3 is moved to the lower part 5
Alternatively, the bag 8 containing the dirt 44 may be transported to a predetermined place while being received by the lower portion 5.
