Hereinafter, embodiments of the waste crushing apparatus disclosed in the present application will be described in detail with reference to the accompanying drawings. The present invention is not limited to the embodiments described below.

FIG. 1 is a schematic diagram showing a filth crushing apparatus according to an embodiment. As shown in FIG. 1, the filth crushing apparatus 1 according to the embodiment is connected to, for example, a toilet bowl TB, crushes the waste discharged from the toilet bowl TB, and sends it to the outside (for example, a sewer pipe). The waste crushing apparatus 1 includes a storage chamber 10, a crushing unit 20, an opening 14, a pressure feeding chamber 30, a discharge port 60, and a prevention unit 40.

The toilet bowl TB is provided with a water supply pipe 4 for supplying cleaning water to the toilet bowl TB, and a water supply valve 3 for opening and closing the water supply pipe 4. The flush water is supplied to the toilet bowl TB through the water supply pipe 4 when the water supply valve 3 is opened by the control device 70.

The toilet bowl TB is connected to the storage chamber 10 of the waste crushing apparatus 1 by the connecting pipe 100. The waste F (see FIG. 5) in the toilet bowl TB and the wash water supplied from the water supply pipe 4 flow into the storage chamber 10 via the connecting pipe 100.

The storage chamber 10 stores wash water and waste F (for example, excrement or toilet paper). The outer wall 11 of the storage chamber 10 is provided with an opening 14 for discharging the wash water and the waste F that have flowed into the storage chamber 10 to the downstream side.

The crushing unit 20 is provided in the storage chamber 10 and crushes the waste F that has flowed into the storage chamber 10. The crushing unit 20 is connected to the driving means 50 (for example, a motor). The driving unit 50 is driven by the control device 70 to rotate the crushing unit 20. The crushing unit 20 stirs the wash water and the filth F stored in the storage chamber 10 so that the filth F collides with the outer wall 11 of the storage chamber 10 and crushes the filth F. The waste F is crushed by the crushing unit 20 until it becomes smaller than the diameter of the opening 14, and when it becomes smaller than the diameter of the opening 14, it flows out of the storage chamber 10 through the opening 14.

The pressure feeding chamber 30 is provided on the downstream side of the opening 14 and pressurizes the waste F that has passed through the opening 14 and sends it to the discharge port 60. The discharge port 60 discharges the waste F to the outside of the waste crushing device 1.

As described above, in the waste material crushing apparatus 1 according to the embodiment, the waste material F is crushed into a predetermined size, specifically, a size smaller than the opening 14 and discharged from the discharge port 60, so that the waste material is discharged from the storage chamber 10. Also, it is possible to prevent the downstream piping from being clogged with dirt.

However, the storage chamber 10 may be mixed with foreign matter having a long and narrow shape, such as a hairpin or a toothpick. Even if such foreign matter could pass through the opening 14, it could not pass through the bent pipe portion, and there was a risk of causing pipe clogging.

Therefore, in the filth crushing apparatus 1 according to the embodiment, the prevention unit 40 that prevents the foreign matter mixed in the storage chamber 10 from flowing out from the storage chamber 10 is provided downstream of the opening 14 and upstream of the discharge port 60. .. As a result, it is possible to prevent the clogging of the pipe even when an elongated foreign substance is mixed.

Next, a specific configuration of the above-described waste crushing apparatus 1 will be described. First, the storage chamber 10 and the prevention unit 40 of the waste crushing apparatus 1 will be described with reference to FIGS. 2 and 3. FIG. 2 is a perspective view showing the waste crushing apparatus 1 from which the prevention unit 40 according to the embodiment is removed. Moreover, FIG. 3 is a perspective view of the waste crushing apparatus 1 according to the embodiment.

As shown in FIG. 2, the storage chamber 10 has a cylindrical outer wall 11. The outer wall 11 has a peripheral wall 12 having a wall surface in the circumferential direction of the storage chamber 10, and a bottom wall 13 (see FIG. 1) connected to the peripheral wall 12 on the lower side of the storage chamber 10. The peripheral wall 12 and the bottom wall 13 form a cylindrical storage chamber 10, and it becomes possible to store the filth F and cleaning water.

A plurality of openings 14 for discharging the filth F crushed in the storage chamber 10 to the downstream side of the storage chamber 10 are formed in the lower portion of the peripheral wall 12. Each of the openings 14 has a circular shape, but it does not have to be a perfect circle and may have an elliptical shape. By discharging only the filth F that is smaller than the diameter of the opening 14 to the downstream side of the storage chamber 10, it is possible to prevent clogging of the filth on the downstream side of the storage chamber 10.

It should be noted that the storage chamber 10 has a connecting portion 17 with the connecting pipe 100 (see FIG. 1 ). The connecting portion 17 is an opening formed from the upper portion of the peripheral wall 12 to the central portion thereof, and is closed by a lid portion 101 (see FIG. 4) described later in the use state. The plurality of openings 14 are formed below the connecting portion 17. The storage chamber 10 also has a mounting portion 18 for mounting the prevention portion 40. The mounting portion 18 has, for example, a protruding portion 18a and a screw 18b. The protruding portion 18a is a member protruding from the peripheral wall 12, and has a screw hole at its tip. The screw 18b is screwed into the screw hole of the protrusion 18a.

As shown in FIG. 3, the prevention portion 40 is formed in a plate shape and in an arc shape along the peripheral wall 12, and is attached to the attachment portion 18 so as to cover the opening 14 on the downstream side of the storage chamber 10. It is fixed to the storage chamber 10 while being separated from the peripheral wall 12. The prevention unit 40 is provided so as to cover the opening 14 in a state of being separated from the peripheral wall 12, and thus allows the foreign matter in the elongated shape to be prevented from flowing out from the storage chamber 10 while allowing the waste F to flow out from the storage chamber 10. ..

Next, a specific configuration of the waste crushing apparatus 1 will be described with reference to FIG. FIG. 4 is a sectional view showing the filth crushing apparatus 1 of the embodiment.

As shown in FIG. 4, the crushing unit 20 is provided in the vicinity of the bottom wall 13, and is formed in a circular shape when the crushing unit 20 is viewed from above the paper surface (that is, along the axial direction of the drive shaft 51). It Further, in order to drive the crushing section 20 formed in a circular shape to rotate, the crushing section 20 is connected to a driving means 50 (for example, a motor) via a drive shaft 51. The driving means 50 is provided above the storage chamber 10.

The flow path 15 on the downstream side of the opening 14 includes the peripheral wall 12 of the storage chamber 10, the outer wall (peripheral wall and bottom wall) of the pumping chamber 30, the box 2 arranged so as to surround the storage chamber 10 and the pumping chamber 30. Formed by. Specifically, the storage chamber 10 and the pressure feed chamber 30 are housed in the box body 2 in a state of being separated from the inner surface of the box body 2, and are provided between the storage chamber 10 and the pressure feed chamber 30 and the box body 2. The gap becomes the flow path 15. The flow channel 15 is a region along the peripheral wall 12 of the storage chamber 10 that is a region of the flow channel 15 and a region on the downstream side of the first region A that extends along the bottom wall of the pumping chamber 30 described below. And a second region B which is a region of the flow path 15. The bottom wall of the pumping chamber 30 and the bottom wall 13 of the storage chamber 10 are substantially parallel to each other.

The pumping chamber 30 provided on the downstream side of the opening 14, specifically, below the storage chamber 10 has an impeller 31. The impeller 31 is connected to the drive means 50 via a drive shaft 51. The pumping chamber 30 is configured such that the impeller 31 is rotated by driving the driving unit 50 and the centrifugal force can be used to pressurize the filth F and the wash water when the filth F and the washing water are sent to the discharge port 60. The bottom wall 13 of the storage chamber 10 corresponds to the upper wall of the pumping chamber 30.

Next, the flow of the cleaning water and the waste F inside the waste crushing apparatus 1 will be described with reference to FIG. FIG. 5: is a figure which shows typically the flow of the wash water and the filth F in the filth crushing apparatus 1 which concerns on embodiment.

The wash water and the waste F flow into the storage chamber 10 via the connecting pipe 100 and are stored in the storage chamber 10. After that, the drive unit 50 is driven by the control device 70 (see FIG. 1), and the crushing unit 20 and the impeller 31 connected to the drive shaft 51 rotate.

As the crushing unit 20 rotates, the wash water and the waste F stored in the storage chamber 10 are moved to the outside from the rotation center of the crushing unit 20 by the centrifugal force, and the waste F collides with the outer wall 11 and the collision occurs. It is crushed by the energy of doing. As a result, the waste F can be reduced. The filth F larger than the size of the opening 14 collides with the outer wall 11 and then moves upward, and then moves to the rotation center side of the crushing unit 20. The flow of the filth F from the rotation center side of the crushing unit 20 to the outside, then moving upward, and then returning to the center direction again is repeated until the filth F becomes smaller than the opening 14.

Further, as the crushing unit 20 rotates, a flow in the direction along the peripheral wall 12 is also formed, and the filth F moves along the peripheral wall 12 and the peripheral wall 12 when moving along the peripheral wall 12. The friction F can be used to crush the waste F.

The filth F crushed in the storage chamber 10 and smaller than the opening 14 is discharged from the opening 14 to the outside of the storage chamber 10, that is, the first region A of the flow path 15.

The waste F discharged from the opening 14 sequentially passes through the first area A and the second area B of the flow path 15 and flows into the pumping chamber 30. Specifically, when the impeller 31 inside the pumping chamber 30 is rotated by the driving means 50, a negative pressure is generated in the vicinity of the center of rotation of the impeller 31, so that the wash water and the dirt F existing in the flow path 15 are pumped. Suctioned into the chamber 30. The suctioned cleaning water and the dirt F are increased in pressure by moving from the rotation center of the impeller 31 to the outside by a centrifugal force, are pressure-fed to the discharge port 60, and are discharged to the outside of the dirt crushing apparatus 1.

By using such a crushing method using a water flow, it is not necessary to provide a crushing blade for crushing the waste F. It is possible to reduce the chance of foreign matter being caught in the crushing blade, and reduce the risk of the driving means 50 locking.

Next, the positional relationship between the opening 14 and the prevention unit 40 will be described with reference to FIG. FIG. 6 is a diagram showing a relationship between the opening 14 and the prevention unit 40 of the waste crushing apparatus 1 according to the embodiment. In FIG. 6, the right side of the outer wall 11 is the inside of the storage chamber 10 and the left side of the outer wall 11 is the outside of the storage chamber 10 when the FIG.

As shown in FIG. 6, the maximum range that can be seen from the inside of the storage chamber 10 through the opening 14 is indicated by a broken line LK. The broken line LK is a line connecting the upstream end 14a of the opening 14 and the downstream end 14b of the opening 14.

The range R surrounded by the broken line LK on the surface of the prevention unit 40 facing the peripheral wall 12 is a range in which foreign matter can flow out from the storage chamber 10. The prevention portion 40 may be formed to have a size that covers at least the range R, that is, a size that covers a range that can be seen from the inside of the storage chamber 10 through the opening 14. In the example shown in FIG. 6, the prevention portion 40 is provided up to a position farther from the center of the opening 14 than the broken line LK (a position farther in the vertical direction of the drawing), and is wider than the range R in the entire circumference of the range R. It covers the range.

Further, the prevention unit 40 is provided near the opening 14 of the outer wall 11 separately from the box body 2. When the minimum length of foreign matter that can be clogged in the flow passage 15 on the downstream side of the storage chamber 10 or the pipe (not shown) on the downstream side of the discharge port 60 is the minimum length L of the foreign matter, the prevention unit 40 causes the peripheral wall 12 It is preferable that the distance between and is shorter than the minimum foreign substance length L.

As described above, the prevention unit 40 is arranged so as to cover the range that can be seen from the inside of the storage chamber 10 through the opening 14, and the distance between the prevention unit 40 and the outer wall 11 is shorter than the minimum foreign substance length L. The preventing portion 40 arranged in this manner collides with the preventing portion 40 when the foreign matter tries to flow out from the storage chamber 10 through the opening 14, so that the foreign matter can be prevented from flowing out of the storage chamber 10.

Next, with reference to FIG. 7, the positional relationship between the opening 14 and the prevention portion 40 described above will be specifically described using mathematical expressions. FIG. 7: is a figure which shows the relationship between the opening 14 and the prevention part 40 of the waste crushing apparatus 1 which concerns on embodiment.

In FIG. 7, description will be made assuming that the foreign matter passes from the upper side to the lower side of the paper surface (that is, along the direction of gravity). FIG. 7 shows the maximum diameter a of the opening 14, the thickness b of the peripheral wall 12, the length c from the lower end of the opening 14 to the lower end of the prevention portion 40, and the distance d between the peripheral wall 12 and the prevention portion 40. There is.

The position of the prevention portion 40 is represented by the following mathematical formulas (1) and (2) using the maximum diameter a, the thickness b, the length c, the interval d, and the minimum foreign substance length L.

Formula (1) is a formula representing an angle through which a foreign substance can pass. a/b represents the maximum angle at which the foreign matter can pass through the opening 14, and c/d represents the maximum angle at which the foreign matter can pass through the flow path 15 between the peripheral wall 12 and the prevention portion 40. When the value of a/b decreases (for example, the thickness b of the peripheral wall 12 increases), the broken line LK (see FIG. 6) moves to the upper side of the drawing.

When the value of c/d further increases (for example, the distance d between the peripheral wall 12 and the prevention portion 40 increases), the broken line LK (see FIG. 6) moves downward in the drawing.

In this way, by making the maximum angle a/b that can pass through the opening 14 smaller than the maximum angle c/d that can pass through the flow path 15 between the outer wall 11 and the prevention portion 40, a/b Since the prevention part 40 is arranged on the extension line of, the foreign substance can be prevented from flowing out.

Further, the mathematical expression (2) is an expression representing the length that the foreign matter can pass through. By setting the maximum length of a straight line connecting the upstream end 14a of the opening 14 and the downstream end 14b of the opening 14 and the prevention portion 40 to be shorter than the minimum length L of foreign matter, the foreign matter is prevented from flowing out from the storage chamber 10. It can be prevented. It should be noted that although the formulas (1) and (2) have been described on the assumption that they pass from the upper side to the lower side of the paper surface, since the opening 14 is formed in a circular shape, the prevention section 40 is represented by the mathematical formulas on the entire circumference. It is provided so as to satisfy (1) and Equation (2).

Since the prevention unit 40 is provided so as to satisfy the mathematical formulas (1) and (2), the foreign matter storage chamber can be used regardless of the angle at which the foreign matter that has flowed into the opening 14 flows out. Outflow from 10 can be prevented.

In the above description of the formulas (1) and (2), it is assumed that the thickness of the foreign matter is extremely thin. However, when the assumed foreign matter is thick, The prevention unit 40 may be provided by multiplying the minimum length L of the foreign matter by a corresponding coefficient. For example, if the thickness of the assumed foreign material is small, the prevention unit 40 is provided based on the value of L×1, and if the thickness of the assumed foreign material is large, the value of L×0.7. Based on the above, the prevention unit 40 is provided.

Next, a modification in which the extending portion 16 is provided in the storage chamber 10 to prevent the foreign matter from flowing out of the storage chamber 10 will be described with reference to FIG. FIG. 8: is a figure which shows the relationship between the opening 14 and the prevention part 40 of the waste crushing apparatus 1 which concerns on a modification. Note that, in FIG. 8, when viewed in the depth direction of the paper, the right side of the peripheral wall 12 is the inside of the storage chamber 10, and the left side of the peripheral wall 12 is the outside of the storage chamber 10.

As shown in FIG. 8, the waste crushing apparatus 1 has an extending portion 16 outside the peripheral wall 12 of the storage chamber 10. The extending portion 16 extends the peripheral wall 12 of the storage chamber 10 toward the downstream side so as to surround the periphery of the downstream side of the opening 14. When the opening 14 has a circular shape, it is preferable that the extending portion 16 also has a circular shape.

A maximum range R′ that can be seen from the inside of the storage chamber 10 through the opening 14 is indicated by a broken line LK. The broken line LK is a line connecting the upstream end 14a of the opening 14 and the downstream end 14b of the opening 14. The arrangement of the prevention unit 40 is as described above.

By providing the extending portion 16, the range visible from the inside of the storage chamber 10 through the opening 14 is narrowed. That is, the range in which the opening 40 should be covered by the prevention portion 40 is narrowed. Therefore, the prevention unit 40 can be downsized, and the cost can be reduced.

If the size of the prevention portion 40 is not changed, the distance d between the peripheral wall 12 and the prevention portion 40 can be increased. By increasing the distance d between the peripheral wall 12 and the prevention unit 40, the pressure rise when the cleaning water or the waste F passes between the peripheral wall 12 and the prevention unit 40 is suppressed, and the drainage performance of the cleaning water or the waste F is reduced. Can be improved.

Next, with reference to FIG. 9, the positional relationship between the opening 14 and the extending portion 16 and the preventing portion 40 described above will be described using Equations (1) and (2). FIG. 9: is a figure which shows the relationship between the opening 14 and the prevention part 40 of the waste crushing apparatus 1 which concerns on a modification.

In FIG. 9, description will be made assuming that the foreign matter passes from the upper side to the lower side of the paper surface (that is, along the gravity direction). In FIG. 9, the maximum diameter a of the opening 14, the combined thickness b of the peripheral wall 12 and the extending portion 16, the length c from the lower end of the opening 14 to the lower end of the preventing portion 40, the extension provided on the peripheral wall 12 are shown. The distance d between the portion 16 and the prevention portion 40 is shown.

The position of the prevention portion 40 will be described using the maximum diameter a, the thickness b, the length c, the interval d, and the minimum foreign substance length L, based on Equations (1) and (2).

By providing the stretched portion 16, the thickness b is increased and the distance d is reduced as compared with the case where the stretched portion 16 is not provided. When this is applied to the mathematical expression (1), the value of a/b becomes small, and the broken line LK (see FIG. 8) moves to the upper side of the drawing.

Further, as the distance d becomes smaller, the value of c/d becomes larger, and the broken line LK (see FIG. 8) moves downward in the drawing.

As described above, by providing the extending portion 16, the relationship of the mathematical expression (1) becomes more prominent, and the foreign matter can be further prevented from flowing out from the storage chamber 10.

As described above, the waste crushing apparatus 1 according to the embodiment includes the prevention unit 40. Therefore, foreign matter mixed in the storage chamber 10 can be prevented from flowing out of the storage chamber 10, and the foreign matter is clogged in the flow path 15 downstream of the storage chamber 10 and the pipe (not shown) downstream of the discharge port 60. Can be prevented.

Particularly in recent years, the toilet bowl TB may be installed not only in the facilities for the elderly but also in the living room of a general household (for example, next to a bed), and there is a risk that the user may accidentally throw a foreign object into the toilet bowl TB. .. Further, when the toilet bowl TB is installed in the living room, the pipe diameter tends to be smaller than that in the case where the toilet TB is installed in the toilet room. Therefore, the pipe is easily clogged.

On the other hand, according to the filth crushing apparatus 1 according to the embodiment, it is possible to prevent the clogging of the pipe due to the foreign matter as described above, and therefore it is possible to eliminate the trouble that tends to occur when the toilet bowl TB is installed in the living room. It is effective in that respect.

In addition, in the above-described embodiment, the waste crushing device 1 is not limited to the toilet bowl TB for the living room, and may be connected to the normal toilet bowl TB installed in the toilet room. In addition, the waste crushing device 1 is not limited to the toilet bowl TB and may be connected to, for example, the drain port of the kitchen.

In the above-described embodiment, an example in which a plurality of openings 14 are provided has been described, but at least one opening 14 may be formed.

Further, in the above-described embodiment, an example in which the prevention unit 40 is configured by one member has been described, but the prevention unit 40 may be provided so as to cover at least the opening 14, and for example, one or It may be composed of a plurality of members corresponding to the plurality of openings 14.

Further, the mounting portion 18 (see FIG. 2) may be configured so that the distance between the prevention portion 40 and the peripheral wall 12 can be changed. As a result, the distance d can be adjusted according to the size of the foreign matter (minimum foreign matter length L) that is desired to be prevented from flowing out.

Further, in the above-described embodiment, the case where the prevention unit 40 is attachable to and detachable from the storage chamber 10 has been described, but the prevention unit 40 may be formed integrally with the storage chamber 10.

Further effects and modifications can be easily derived by those skilled in the art. Therefore, the broader aspects of the present invention are not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
