Description

  The present invention relates to a draining device for manually draining garbage.

Most of the weight of garbage generated in ordinary households is moisture, and even if the garbage is drained, the weight of the garbage can be considerably reduced. In addition, the efficiency of garbage truck transportation and waste incineration facilities Incineration efficiency is improved and the amount of CO ₂ generated can be reduced. For this reason, drainage of garbage is encouraged in each municipality, and on the websites etc. operated by each municipality, concrete examples such as putting garbage in a triangular corner, using a drainage net, or manually squeezing before disposal Means are introduced. However, the amount of water that can be removed by these means is known, and there is resistance to hand-drawing of garbage.

  On the other hand, as a conventional draining device for manually draining garbage, a compression type as shown in Patent Documents 1 to 3 below, a rotation type as shown in Patent Documents 4 to 6 below, and the like are known. . However, the compression-type draining device compresses the garbage in the garbage container, squeezes out the moisture, and then releases the compressive force, so that the compressed garbage is expanded, and the squeezed moisture is absorbed by the water again. Therefore, there is a problem that draining becomes insufficient. In addition, a rotary drainer is a device that rotates a container (basket) that contains garbage and centrifuges (drains) the water contained in the garbage. However, the garbage container must be rotated at high speed. If the drainage is insufficient and the high-speed rotation is possible, the mechanism for rotation becomes complicated, and there is a problem that the cost increases and the maintainability decreases.

  In addition, electric heat (air dry) garbage dryers are also commercially available for general household use. However, not only the apparatus itself is expensive, but also the running cost is high, and the bad odor generated during drying and the maintenance are difficult.

JP 2001-259594 A Japanese Patent Laid-Open No. 2003-2401 JP 2003-135909 A Japanese Utility Model Publication No. 6-8307 Utility Model Registration No. 3066128 JP 2006-8319 A

  The present invention has been made in view of the above-mentioned problems of the conventional draining device, and is capable of draining the garbage at a high level by a relatively simple mechanism that is cheaper than a garbage dryer and the like. An object of the present invention is to provide a manual draining device.

The garbage draining apparatus according to the present invention includes a draining container in which holes through which a liquid can pass are formed in a side wall and a bottom wall, an outer container that contains the draining container and rotatably supports the draining container, and the outer container An upper lid that closes an upper opening of the upper lid, a rotary shaft that vertically passes through a hole formed in the upper lid and is rotatable and axially movable with respect to the upper lid, and an upper portion of the draining container that is fixed to a lower end of the rotary shaft A garbage pushing plate that is allowed to enter the draining container through the opening, and a handle attached to the rotating shaft outside the upper lid.
In this draining device, when the rotating shaft is lowered to press the garbage pushing plate against the garbage and the rotating shaft is rotated in that state, the draining container is rotated by the friction force between the garbage pushing plate and the garbage, A rotation transmission part is formed on the outer periphery of the garbage pushing plate, and a receiving part that engages with the rotation transmission part is formed on the side wall of the draining container, and the rotation of the garbage pushing plate is transmitted to the draining container by the engagement of both parts. You can also make it.

When using this drainer, after pressing down the rotating shaft and compressing the garbage with the garbage push plate to squeeze out the moisture, even if part or all of the pushing force is released, the garbage is easily compressed. It is desirable that the water is not eliminated (when the garbage expands, the squeezed water is absorbed again). For this purpose, the draining device can have the following specific configuration.
(1) A friction member that presses the rotating shaft is installed on the upper lid, and a resistance force is applied to the axial movement of the rotating shaft by the friction member.
(2) A large number of circumferential grooves are formed around the rotation shaft, and an elastic body that fits into the circumferential grooves is provided on the upper lid. This elastic body is elastically deformed in the outer diameter direction of the rotating shaft and can escape from the circumferential groove.
(3) A male screw is formed around the rotation shaft, and an elastic body that fits into the valley of the male screw is installed on the upper lid. This elastic body is elastically deformed in the outer diameter direction of the rotating shaft and can escape from the valley of the male screw.

  In this draining device, the rotating shaft is manually pushed down, the garbage in the draining container is compressed by the garbage pushing plate to squeeze out the water in the garbage, and the rotating shaft is manually rotated simultaneously with or after this compression. The draining container is rotated with the garbage pushing plate, and the water in the garbage, particularly the water squeezed by compression, is discharged out of the draining container by centrifugal force. As the draining mechanism uses both compression and rotation, unlike conventional compression-type draining devices, the compressed and squeezed water is prevented from being absorbed again into the garbage, and the conventional rotation Unlike the type of draining device, the water that has been compressed and squeezed out is discharged by the centrifugal force of rotation, and therefore a mechanism that enables high-speed rotation is not particularly necessary. Therefore, it is possible to drain the garbage with an inexpensive and relatively simple mechanism.

Further, when the mechanisms shown in the above (1) to (3) are employed, the rotating shaft and the garbage pushing plate are stopped at appropriate positions even if a part or all of the pressing force to the rotating shaft is released. Because the compressed state of garbage can be maintained, just rotate the rotating shaft (without rotating it in the pressed state) by turning the handle, and the water squeezed by the compression is discharged out of the draining container. can do.
After draining, the upper lid is removed, the draining container is taken out from the outer container, and the garbage after draining is discarded into a plastic bag or container for disposal. Moreover, if this garbage is processed with the said garbage dryer, the running cost of a garbage dryer can be lowered | hung.

Hereinafter, with reference to FIGS. 1-8, the water draining apparatus which concerns on this invention is demonstrated concretely.
A draining device shown in FIG. 1 includes a draining container 1 for containing garbage, an outer container 2 that accommodates the draining container 1 and rotatably supports the draining container 1, and an upper lid 3 that closes an upper opening of the outer container 2. The press rotator 4 is used to drain the garbage in the draining container 1.
The draining container 1 is, for example, a plastic basket-shaped container, and has a cylindrical side wall 5 and a bottom wall 6. As shown in FIG. 2, liquid can pass through the side wall 5 and the bottom wall 6, but garbage is not collected. A number of holes 7 that are difficult to pass are formed. A cylindrical portion 8 having a relatively small diameter is integrally formed at the center of the bottom surface of the bottom wall 6, and a cylindrical body 9 having a relatively large diameter is attached concentrically with the cylindrical portion 8.

The outer container 2 is made of, for example, plastic, and includes a cylindrical side wall 11 and a bottom wall 12, and the bottom wall 12 has a number of holes 13 that are large enough to allow liquid to pass through. An upper surface of the bottom wall 12 is flat, a shaft 14 is integrally formed at the center, and stands upright. A plurality of legs 14 for floating the container main body from the bottom of the sink, for example, are integrally formed on the lower surface of the bottom wall 12. Is formed. The shaft 14 is fitted in the hole of the cylindrical portion 8 of the draining container 1 and supports the draining container 1 in a rotatable manner. The cylindrical body 9 attached to the draining container 1 is for stabilizing the rotation of the draining container 1 and for receiving a pressing force applied to the draining container 1 from the pressing rotator 4. Rotate and slide on the top surface.
The upper lid 3 is made of plastic, for example, and a cylindrical portion 15 is formed at the center thereof. A rotation shaft 17 of the pressing rotator 4 described later passes through the hole 16 of the cylindrical portion 15, and the cylindrical portion 15 functions as a bearing for rotation of the rotation shaft 17 and thrust.

The pressing rotator 4 includes a cylindrical or rod-shaped rotating shaft 17 that passes through the hole 16 so as to be rotatable and movable in the axial direction, a disk-shaped garbage pushing plate 18 fixed to the lower end of the rotating shaft 17, and a rotation It comprises a handle 19 fixed to the upper end of the shaft 17 and a knob 21 attached to the handle 19 so as to be rotatable. The garbage pushing plate 18 has an outer diameter slightly smaller than the inner diameter of the draining container 1 and can enter the draining container 1 from the upper opening of the draining container 1 (movable up and down in the draining container 1). The rotating shaft 17, the garbage pushing plate 18, the handle 19 and the knob 21 can all be made of plastic.
When the rotating shaft 17 is pushed down, the garbage pushing plate 18 descends in the draining container 1, and when the rotating shaft 17 is rotated by holding the knob 21, the garbage pushing plate 18 rotates in the draining container 1.

  When the draining device is used, the draining container 1 or the outer container 2 in a state in which the draining container 1 is accommodated is disposed, for example, at the corner of the sink, and the garbage generated in the kitchen is put into the draining container 1. When the garbage is filled in the draining container 1 or when kitchen work is finished, the upper lid 3 is put on the outer container 2 while the draining container 1 is accommodated in the outer container 2. At the same time, the garbage pushing plate 18 is set at a predetermined position. That is, for example, when the garbage is contained in the draining container 1, the garbage pushing plate 18 enters the draining container 1 as shown in FIG. In such a case, it does not enter the draining container 1 and is positioned immediately above the opening.

Subsequently, the rotary shaft 17 is pushed down (at this time, the rotary shaft 17 may be pushed down directly, or may be pushed down by holding the knob 21), whereby the garbage pushing plate 18 is pushed down in the draining container 1, and the garbage is removed. Compress and squeeze out moisture in the garbage. A part of this moisture is discharged out of the draining container 1 through the hole 7, and a part of the moisture stays in the draining container 1.
Next, when the rotary shaft 17 is rotated while holding the knob 21 while maintaining the pressing force, the draining container 1 is rotated by the friction force of the garbage pushing plate 18 and the garbage in the draining container 1, The water staying in the draining container 1 is discharged out of the draining container 1 through the hole 7 by centrifugal force, and the water in the garbage is further discharged by centrifugal force. It should be noted that the rotation process of the rotary shaft 17 (the garbage compression process) and the rotation can be performed simultaneously.

Moisture discharged from the draining container 1 through the hole 7 enters the outer container 2 and is discharged into the sink through the hole 13.
After the moisture is discharged, the upper lid 3 is removed from the outer container 2 and removed together with the pressing rotator 4, and the garbage in which the moisture in the draining container 1 is reduced is thrown away into other prepared garbage bags or garbage containers. Or this garbage can also be processed with a garbage dryer.

FIG. 3 illustrates a mechanism for rotating the draining container 1 more reliably with the rotation of the rotating shaft 17. Locking pieces 22 serving as rotation transmission portions are integrally formed at a plurality of locations on the outer periphery of the garbage pushing plate 18, and locking pieces serving as receiving portions for the locking pieces 22 are formed on the inner surface of the side wall 5 of the draining container 1. 23 is integrally formed. The locking piece 22 extends in the thickness direction of the garbage pushing plate 18 and has a length similar to the thickness. The locking piece 23 extends from the opening to the vicinity of the lower end in the depth direction of the draining container 1. .
When the garbage pushing plate 18 enters the draining container 1 in the vertical direction and rotates (see the arrow in FIG. 3), both the locking pieces 22 and 23 are engaged, and the rotation shaft 17 and the garbage pushing plate 18 rotate. Is directly transmitted to the draining container 1.

The rotation transmission part (locking piece 22) of the garbage pushing plate 18 and the receiving part (locking piece 23) of the draining container 1 are formed integrally with the garbage pushing plate 18 and the draining container 1, respectively. Instead, what is formed as a separate body may be fixed to the garbage pushing plate 18 and the draining container 1 by post-processing. Moreover, the rotation transmission part of the garbage pushing board 18 and the receiving part of the draining container 1 are not limited to said form, respectively.
As a mechanism for more reliably rotating the draining container 1 with the rotation of the rotating shaft 17, an engaging portion for the garbage, for example, a spike (projection) that bites into the garbage is formed on the lower surface of the garbage pushing plate 18. You can also keep it. By this engagement part, rotation of the garbage pushing plate 18 is more reliably transmitted to the draining container 1 through the garbage.

FIGS. 4-6 shows the other draining apparatus which concerns on this invention, especially the other form of the press rotation tool 4. FIG. In addition, in FIGS. 4-6, the same number is provided to the site | part substantially the same as the draining apparatus shown in FIG.
In the draining device shown in FIG. 4, the main difference from the draining device shown in FIG. 1 is that the male screw 24 is formed on the rotary shaft 17 of the pressing rotary tool 4 and the elasticity that fits into the valley of the male screw 24 from the left and right. The body (wire spring 25) is installed on the upper lid 3.

In the vicinity of the cylindrical body 15 on the lower surface of the upper lid 3, three support pins 26 to 28 each having a head portion are erected, and a linear spring 25 bent symmetrically is provided at the center portion and both end portions. It is hooked in the form of being wound around the support pins 26 to 28 in the vicinity. A relatively gently curved portion between the center portion and both end portions of the wire spring 25 is fitted into the valley of the male screw 24 at the left and right facing positions.
In the pressing rotator 4, when the rotary shaft 17 is rotated with the knob 21, the wire spring 25 functions as a kind of female screw, and the rotary shaft 17 and the garbage pushing plate 18 move in the axial direction. The wire spring 25 is elastically deformed in the outer diameter direction of the rotating shaft and can escape from the valley of the male screw 24.

  In the case of this draining device, the garbage in the draining container 1 can be compressed and the draining container 1 can be rotated only by rotating the knob 21. When the pressing rotary tool 4 is set and the knob 21 is rotated as shown in FIG. 4, in the initial stage, the rotating shaft 17 rotates and the garbage pushing plate 18 descends while rotating, and the garbage in the draining container 1 is removed. The draining container 1 is rotated by being pressed and compressed, and the frictional force corresponding to the pressing force is rotated, whereby the moisture in the garbage is squeezed out and discharged out of the draining container 1. As the garbage is compressed, a reaction force acts on the garbage pushing plate 18 from the garbage. The upper lid 3 can be fixed to the opening of the outer container 2 so that the upper lid 3 does not open due to the reaction force. desirable.

  As the garbage is compressed, the reaction force acting on the garbage pushing plate 18 from the garbage increases, and even if the rotating shaft 17 is rotated, the rotating shaft 17 is hardly lowered, and at the same time, the wire spring 25 is connected to the male screw 24. It is pushed by the mountain and elastically deforms (pushes and spreads) in the outer diameter direction of the rotating shaft 17. Subsequently, when the reaction force acting on the garbage pushing plate 18 exceeds a predetermined value, even if the rotary shaft 17 is rotated, the wire spring 25 escapes from the valley of the male screw 24 and passes over the adjacent mountain to the next valley. The operation of dropping is repeated, and the rotary shaft 17 and the garbage pushing plate 18 do not descend (a state where no further compression of the garbage occurs), and thereafter the rotation of the garbage pushing plate 18 and the accompanying rotation of the draining container 1 Only occurs. During this time, the garbage in the draining container 1 is subjected to a compressive force by the garbage pushing plate 18.

When the draining of the garbage is completed through these steps, the rotary shaft 17 is rotated in the reverse direction by the knob 21, the rotary shaft 17 and the garbage push plate 18 are lifted to release the garbage, and the upper lid 3 is removed. It is removed from the outer container 2 and removed together with the pressing rotator 4.
In this drainer, when the rotary shaft 17 is pushed down with a predetermined pressing force or more, the rotary shaft 17 pushes down the wire spring 25 and descends. (A mechanism similar to the draining device of FIG. 7 described later).
4-6, the cylindrical body 9 shown in FIG. 1, the rotation transmission part (locking side 22) and the receiving part (locking side 23) shown in FIG. 3 can be provided. Further, the engaging portion (spike) can be formed on the lower surface of the garbage pushing plate 18.

In FIG. 7, the other draining apparatus which concerns on this invention, especially the other form of the press rotary tool 4 are shown. In FIG. 7, the same numbers are assigned to substantially the same parts as the draining device shown in FIG.
In the pressing rotator 4 shown in FIG. 7, the difference from the pressing rotator 4 shown in FIG. 4 is that a large number of ring-shaped circumferential grooves 29 are formed at equal intervals on the outer periphery of the rotating shaft 17 instead of the male screw 24. This is only the point where the elastic body (wire spring 25) is fitted in the left and right facing positions of the circumferential groove 29.
In this draining device, when a pressing force in the axial direction is applied to the rotating shaft 17, the wire spring 25 is pressed by the ridges 31 between the circumferential grooves 29 to elastically deform (push and expand) in the outer diameter direction of the rotating shaft 17. The wire spring 25 can escape from the circumferential groove 29 when the pressing force exceeds a predetermined value. The wire spring 25 that has escaped from the circumferential groove 29 passes over the adjacent ridges 31 and falls into the next circumferential groove 29. At the same time, the rotary shaft 17 moves in the axial direction (direction of the pressing force) by a predetermined distance.

  When using this draining device, after setting the pressing rotator 4, first, the rotating shaft 17 is pushed down, the garbage in the draining device 1 is pressed and compressed by the garbage pushing plate 18, and the moisture in the garbage is removed. Squeeze out. While the rotary shaft 17 is being pushed down, the wire spring 25 is elastically deformed in the outer diameter direction, escapes from the circumferential groove 29, and repeats the operation of passing over the adjacent ridges 31 and falling into the next circumferential groove 29. Even if the pressing force of the rotating shaft 17 is released at the stage when the compression is finished, the wire spring 25 is fitted in the circumferential groove 29, so that the reaction force applied from the garbage to the garbage pushing plate 18 is the predetermined value. As long as it does not exceed, the rotating shaft 17 does not return (raise), and the compressed state of the garbage is maintained.

Subsequently, when the rotary shaft 17 is rotated with the knob 21, the garbage pushing plate 18 is rotated, and the draining container 1 is rotated by the frictional force of the garbage in the draining container 1. At this time, even if the rotating shaft 17 is not pressed downward, the garbage is in a compressed state. Therefore, by simply holding the knob 21 and rotating the rotating shaft 17, the garbage can be drained sufficiently. It should be noted that the above-described pressing of the rotating shaft 17 (compression of garbage) and the rotation of the rotating shaft 17 can be performed simultaneously.
When draining of garbage is completed, the upper lid 3 is removed from the outer container 2 and removed together with the pressing rotator 4.
Also in the draining device shown in FIG. 7, the cylindrical body 9 shown in FIG. 1, the rotation transmission part (locking side 22) and the receiving part (locking side 23) shown in FIG. 3 can be provided. Further, the engaging portion (projection) can be formed on the lower surface of the garbage pushing plate 18.

In FIG. 8, the other draining apparatus which concerns on this invention, especially the other form of the press rotary tool 4 are shown. In addition, in FIG. 8, the same number is provided to the site | part substantially the same as the draining apparatus shown in FIG.
The only difference between the pressing rotator 4 shown in FIG. 8 and the pressing rotator 4 shown in FIG. 1 is that a ring-shaped friction member 32 that presses against the rotating shaft 17 is provided on the upper lid 3.
The friction member 32 is installed around the hole 16 on the lower surface of the upper lid 3, and the rotating shaft 17 is in sliding contact with the hole 33 formed in the friction member 32, and provides resistance to the axial movement of the rotating shaft 17. ing. As the friction member 32, it is desirable to appropriately use an elastic material having a high friction coefficient with respect to the rotating shaft 17, such as rubber or soft resin.

  When using this draining device, after setting the pressing rotator 4, first, the rotating shaft 17 is pushed down, the garbage in the draining device 1 is pressed and compressed by the garbage pushing plate 18, and the moisture in the garbage is removed. Squeeze out. Even if the pressing force of the rotating shaft 17 is released at the stage when the compression is completed, the friction member 32 is pressed against the rotating shaft 17 and resists the axial movement of the rotating shaft 17, so As long as the reaction force applied to the garbage pushing plate 18 does not exceed the resistance force, the rotating shaft 17 does not return (raise) and the garbage is compressed.

Subsequently, when the rotary shaft 17 is rotated with the knob 21, the draining container 1 is rotated by the friction force between the garbage pushing plate 18 and the garbage in the draining container 1. At this time, even if the rotating shaft 17 is not pressed downward, the garbage is in a compressed state. Therefore, the garbage can be sufficiently drained by simply rotating the rotating shaft 17 with the knob 21. It should be noted that the rotary shaft 17 can be pushed down (compression of garbage) and rotated simultaneously.
When draining of garbage is completed, the upper lid 3 is removed from the outer container 2 and removed together with the pressing rotator 4.
Also in the draining device shown in FIG. 8, the cylindrical body 9 shown in FIG. 1, the rotation transmission part (locking side 22) and the receiving part (locking side 23) shown in FIG. 3 can be provided. Further, the engaging portion (projection) can be formed on the lower surface of the garbage pushing plate 18.

In FIG. 9, the other form of the draining container 1 which concerns on this invention is shown. In addition, in FIG. 9, the same number is provided to the site | part substantially the same as the draining container 1 shown in FIG.
The main difference between the draining container 1 shown in FIG. 9 and the draining container 1 shown in FIG. 1 is that the bottom wall 6 is formed on an inclined surface having a lower outer peripheral side. Thereby, the draining effect by compression and rotation becomes high.

In addition, it cannot be overemphasized that the draining apparatus which concerns on this invention is not restricted to said form. For example, it can take the following forms.
(1) The hole 7 of the draining container 1 can take an appropriate shape such as a vertically long hole like a normal monkey.
(2) A hole 13 is formed in the bottom wall 12 of the outer container 2 so that the moisture discharged from the draining container 1 is discharged into the sink, but a discharge port with a cock at an appropriate position of the outer container 2 May be provided so as not to run down.
(3) The outer container 2 may be provided with a mechanism for fixing it at a predetermined position (such as a side wall or a bottom wall) in the sink, such as a hook or a suction cup, or a handle for carrying.
