By the way, foreign substances other than filth (for example, a hard lighter, a soft diaper, a handkerchief, etc.) may be mistakenly flushed to the toilet. If such foreign matter is mistakenly flushed into the toilet, the foreign matter is not completely crushed by the crushing part, and the foreign matter is caught between the crushing part and the storage tank, or the crushing part and the foreign matter are entangled. This causes a problem that the motor (drive unit) driving the unit is locked. If the motor driving the pulverizing unit is locked, the pulverizing unit cannot pulverize the dirt or the like, so that the dirt or the like cannot flow to the downstream side.
In addition, since the waste crushing apparatus has a function unit for driving the crushing unit by a motor or the like, it is necessary to periodically perform maintenance of the function unit and the like.

  Therefore, by providing an inspection port for inspecting the crushing section in the waste crushing apparatus, foreign substances in the crushing section and the storage tank can be removed, and maintenance of the functional section and the like can be performed.

Therefore, it becomes easy to insert an instrument such as a hand or a cleaning tool from the inspection port, and it is possible to improve the maintainability of the crushing unit and the like.

  Also, in the waste crushing apparatus according to one aspect of the present invention, preferably, the waste supply path has a water flow forming means for forming a flow such that washing water and waste flow from the toilet toward the buffer chamber. are doing.

Here, if the buffer chamber is provided, the buffer chamber is divided into a portion through which sewage passes and a portion through which sewage does not pass, and there is a concern that filth accumulates at the boundary. For this reason, there is a concern that the user or the inspector may feel uncomfortable if the user looks into the inspection port in a state where the waste is accumulated.
Therefore, according to this configuration, since the waste supply path has the water flow forming means for forming a flow such that the wash water and the waste flow from the toilet toward the buffer chamber, the waste water flows through the waste supply path. Each time, the buffer chamber can be washed with the water flow formed by the water flow forming means. For this reason, it is possible to suppress the accumulation of dirt in the buffer chamber, and it is possible to further suppress the accumulation of dirt from being seen when looking through the inspection port.

Further, the drive shaft 64 is connected to the crushing teeth 44 and the impeller 54 inside the crushing chamber 42 and the pressure feeding chamber 52, respectively. That is, the grinding teeth 44 and the impeller 54 are connected to the motor 62 via the drive shaft 64.

<Configuration of tank body>
Next, a tank body according to an embodiment of the present invention will be described in detail with reference to FIGS.

  FIG. 2 is a perspective view of the tank body according to one embodiment of the present invention. FIG. 3 is a top view of the tank main body according to the embodiment of the present invention. FIG. 4 is a top view of the tank main body when the tank lid according to the embodiment of the present invention is omitted. FIG. 5 is a sectional view taken along line VV in FIG. FIG. 6 is a front view of the tank body according to one embodiment of the present invention.

As shown in FIGS. 2 to 4, in the tank body TH, a storage tank 30 is provided on the left side, and a waste supply path 20 is provided on the right side. More specifically, the upstream portion of the waste supply passage 20 extends rearward from the inlet 20a side (front side), and the downstream portion of the waste supply passage 20 is located on the storage tank 30 side (left side). ) And connected to the pulverizing section 40.
The storage tank 30 and the waste supply path 20 of the tank body TH are open upward, and a tank lid 70 is provided so as to cover the opening of the tank body TH.
In the present embodiment, the tank body TH and the tank lid 70 are separate bodies, but the tank body TH and the tank lid 70 may be formed integrally.

The filth supply path 20 has a buffer chamber 22 that bulges a part of the filth supply path 20. Specifically, in the filth supply path 20, a part of the flow path is bulged in a direction different from the direction in which the downstream portion of the filth supply path 20 is bent, that is, in a direction opposite to the storage tank 30 side. A buffer chamber 22 is formed.
As described above, since the waste supply path 20 has the buffer chamber 22, the wastewater can be stored in the buffer chamber 22 when the wastewater from the crushing unit 40 flows backward. Therefore, the backflow of the sewage from the filth supply path 20 to the toilet TB side can be suppressed.

  Further, the bottom surface of the flow channel forming the buffer chamber 22 is inclined downward toward the downstream side (toward the storage tank 30) (see FIG. 5). As a result, the washing water, filth, and the like flowing into the buffer chamber 22 flow smoothly toward the downstream side (the storage tank 30 side). Therefore, it is possible to suppress the cleaning water and the dirt from remaining in the buffer chamber 22.

  In addition, an inspection port 80 for inspecting the crushing unit 40 is provided above the tank body TH. Specifically, the inspection port 80 is provided in the tank cover 70 corresponding to the upper wall surface of the waste supply passage 20 and the buffer chamber 22. That is, the inspection port 80 is provided on the waste supply passage 20 and at least in a part of the buffer chamber 22. Further, the inspection opening 80 is provided with an inspection opening cover (not shown) that covers an opening of the inspection opening 80.

Here, as shown in FIG. 5, the inspection port 80 is configured such that at least one of the crushing unit 40 and the waste supply path 20 is visible when, for example, an inspector or a user of the waste crushing apparatus 1 looks into the inspection port 80. Are located in More specifically, when the inspection port 80 is viewed from the front of the opening of the inspection port 80, that is, when the inspection port 80 is viewed from above, a part of the buffer chamber 22 and a part of the waste supply passage 20 (the buffer chamber 20). An inspection port 80 is provided at a position where the portion of the waste supply path 20 other than 22 can be seen. On the other hand, when the inspection port 80 is viewed obliquely from the front of the opening of the inspection port 80, that is, when the inspection port 80 is viewed obliquely downward from above, at least one of the pulverizing sections 40 is An inspection port 80 is provided at a position where the part can be seen.
In other words, when the inspection port 80 is viewed from the front of the opening of the inspection port 80, the crushing unit 40 is not visible, and only the waste supply path 20 is visible. An inspection port 80 is provided at a position where the pulverizing section 40 can be seen when looking into the camera. According to this configuration, it is possible to easily perform the inspection work on the crushing unit 40 and further suppress the appearance of the accumulation of dirt when looking through the inspection port 80. In addition, when the inspection port 80 is viewed from the front of the opening of the inspection port 80, the inspection port 80 is arranged so that at least one of the crushing unit 40 and the waste supply path 20 is visible. However, it is possible to prevent unnecessary parts from being seen. For this reason, it is possible to suppress a situation in which a component requiring no maintenance is operated by, for example, an inspector or a user who looks through the inspection port 80 and the waste crushing apparatus 1 malfunctions.

  Considering the workability of the inspector, such as the inspector approaching the crushing unit 40 while looking into the inspection port 80, the angle at which the crushing unit 40 can be seen through the inspection port 80 is set in front of the opening of the inspection port 80. On the other hand, the angle is preferably in the range of 30 ° to 60 °.

  Further, in the present embodiment, the configuration in which only the waste supply passage 20 is visible when the inspection port 80 is viewed from the front of the inspection port 80 is described. However, when the inspection port 80 is viewed from the front of the inspection port 80. A configuration in which a part of the crushing unit 40 can be seen from the front, or a configuration in which only a part of the crushing unit 40 and a part of the waste supply path 20 are visible when the inspection port 80 is viewed from the front of the opening of the inspection port 80 It may be.

Returning to FIG. 4, the waste supply path 20 has a convex portion 24 that forms a flow of the wash water and the waste so that the wash water and the waste flow from the toilet bowl TB toward the buffer chamber 22. The convex portion 24 protrudes from the wall surface forming the waste supply passage 20. Specifically, the convex portion 24 protrudes from the left wall surface of the upstream portion of the waste supply passage 20 toward the right side where the buffer chamber 22 is formed. In addition, the convex portion 24 is formed from the upper wall portion on the left side of the upstream portion of the waste supply passage 20 to the bottom surface (see FIG. 6).
In the present embodiment, the projection 24 functions as a water flow forming unit.

Also, as shown in FIG. 6, when the inflow port 20a of the filth supply path 20 is viewed from the front side with respect to the opening area of the inflow port 20a when the inflow port 20a of the filth supply path 20 is viewed from the front side. The projection 24 is formed such that the projected area of the projection 24 to the opening of the inflow port 20a is about 10% to 30%.
As described above, if the projected area of the convex portion 24 to the inlet 20a is 10% to 30% of the opening area of the inlet 20a, the waste from the inlet 20a via the convex portion 24 is contaminated. Since the pressure loss of the sewage flowing through the supply path 20 can be suppressed, it is more preferable from the viewpoint of maintaining the drainage performance.

<Operation and Action>
Next, an operation and an operation of the waste crushing apparatus according to the embodiment of the present invention will be described with reference to FIG.

  FIG. 7 is an explanatory diagram schematically showing the flow of sewage in the tank body according to one embodiment of the present invention.

As shown in FIG. 7, the wash water and the waste discharged from the toilet-side discharge port 4a of the toilet TB flow into the waste supply passage 20 from the inflow port 20a. Further, the washing water and the dirt flowing into the dirt supply passage 20 from the inflow port 20 a flow toward the buffer chamber 22 by the convex portion 24 in the upstream part of the dirt supply passage 20.
More specifically, the washing water and the dirt flow from the front to the rear in the upstream part of the dirt supply passage 20. When the washing water and the filth reach the convex portion 24, the flow direction is changed by the convex portion 24, and flows toward the buffer chamber 22 along the convex portion 24. The washing water and the filth flowing into the buffer chamber 22 flow toward the downstream of the filth supply path 20 as they are, and flow from the outlet 20 b to the crushing unit 40. The washing water and filth flowing into the crushing unit 40 are stirred and crushed in the crushing unit 40, and flow to the pressure feeding unit 50 via the flow path 34. At this time, the filth is crushed by the crushing unit 40 into a predetermined size, specifically, a size smaller than the discharge hole 48. Then, the washing water and filth flowing from the pulverizing unit 40 to the pumping unit 50 via the flow path 34 are pumped from the pumping unit 50 to the drain pipe 14.

  Thus, the waste crushing apparatus 1 according to one embodiment of the present invention crushes waste into a predetermined size, specifically, a size smaller than the discharge hole 48 and discharges the waste through the discharge port 32. It is possible to prevent clogging with dirt in a pipe (for example, the drain pipe 14) downstream of the storage tank 30.

  By the way, for example, a hard lighter, a soft diaper, a handkerchief, or the like may be mistakenly flown into the storage tank 30 and the crushing unit 40. If such foreign matter is erroneously flowed into the toilet bowl TB, the foreign matter cannot be completely crushed by the crushing unit 40 and is caught between the crushing unit 40 and the storage tank 30 or the crushing unit 40 and the foreign matter are entangled. For example, there is a concern that a problem may occur that the motor 62 driving the crushing unit 40 is locked. In preparation for such a case, the waste crushing apparatus 1 is provided with an inspection port 80 for checking the crushing unit 40.

  However, if the inspection port 80 is provided, when foreign substances are removed through the inspection port 80, the dirt and the like accumulated inside the tank main body TH of the waste crushing apparatus 1 can be seen from the inspection port 80, and the inspector and the user can use the waste. There is a concern that it may cause discomfort to the elderly. Here, in order to suppress the accumulation of dirt in the dirt supply path 20, it is preferable that the flow path of the dirt supply path 20 is formed to be as narrow as possible. However, if the dirt supply path 20 is narrowed, When a backflow occurs from the crushing unit 40 to the waste supply path 20, there is a problem that the wastewater flows backward from the waste supply path 20 to the toilet TB side. Further, when the inspection port 80 is provided in the waste supply path 20, if the waste supply path 20 is narrowed, the inspection port 80 is reduced accordingly, and the maintainability of the crushing unit 40 and the like is reduced. There are also concerns.

  Therefore, in the filth crushing apparatus 1 according to one embodiment of the present invention, since the filth supply path 20 has the buffer chamber 22, when the backflow of the sewage from the crushing unit 40 occurs, the Sewage can be stored. Therefore, the backflow of the sewage from the filth supply path 20 to the toilet TB side can be suppressed.

Further, the inspection port 80 is provided on the waste supply passage 20 and at least a part thereof is provided in the buffer chamber 22. That is, the inspection port 80 is provided on a flow path through which the waste is conveyed. Here, since the washing water flows together with the waste in the waste supply path 20, the waste is not easily deposited. Since the inspection port 80 is provided on the waste supply path 20, it is possible to prevent the accumulation of waste when the inspection port 80 is looked through. Therefore, for example, an inspector or a user can perform maintenance more comfortably.
Further, since the inspection port 80 is provided in at least a part of the buffer chamber 22, the inspection port 80 is formed larger than the case where the buffer chamber 22 is not provided, by the amount formed in the buffer chamber 22. can do. Therefore, it becomes easy to insert an instrument such as a hand or a cleaning tool from the inspection port 80, and the maintainability of the crushing unit 40 and the like can be improved.

Further, since the filth supply path 20 has the convex portion 24 that forms a flow such that the rinsing water and the filth flow from the toilet TB toward the buffer chamber 22, the rinsing water and the filth flowing through the filth supply path 20 are provided. Flows through the buffer chamber 22 so as to bypass the buffer chamber 22 when viewed from above. More specifically, the washing water and the dirt flowing from the toilet TB to the dirt supply passage 20 first collide with the projection 24. The washing water and the filth that collided with the convex portion 24 flow into the buffer chamber 22 along the convex portion 24 while the flow thereof is regulated by the convex portion 24. The washing water and the dirt flowing into the buffer chamber 22 circulate along the wall surface inside the buffer chamber 22 and flow toward the downstream side (outflow port 20b). Thus, the buffer chamber 22 can be washed with the water flow formed by the projections 24 each time the wastewater flows through the waste supply passage 20. Therefore, the accumulation of dirt in the buffer chamber 22 can be suppressed, and when the inspection port 80 is looked through, the accumulation of dirt can be further suppressed.
In addition, in the present embodiment, since the convex portion 24 is a water flow forming means, it is possible to suppress the accumulation of dirt in the buffer chamber 22 with a simpler configuration, and to reduce the accumulation of dirt when looking through the inspection port 80. The visibility can be further suppressed.

<Other embodiments>
Next, a configuration of a waste crusher according to another embodiment of the present invention will be described with reference to FIG.

  FIG. 8 is a top view of a tank main body according to another embodiment of the present invention. Note that the tank lid is omitted for convenience of explanation.

  As shown in FIG. 8, the tank main body TH of the waste crushing apparatus 1 according to another embodiment of the present invention includes a waste supply path 20, a storage tank 30, a crushing section 40, a pressure feeding section 50, and a driving means 60. And The filth supply path 20 is a flow path for guiding washing water and filth (for example, excrement and toilet paper) from the toilet bowl TB to the crushing unit 40. The inflow port 20a of the filth supply path 20 has a drainage (not shown). It is connected to the toilet-side discharge port 4a via a socket or the like.

In the filth supply path 20, a tangent A along the flow path wall surface of the filth supply path 20 upstream of the buffer chamber 22 and at least a part of the area of the buffer chamber 22 are formed to intersect. Specifically, a tangent line A that is located on the upstream side of the buffer chamber 22 and extends along a part of the side wall surface of the flow path of the waste supply path 20 that is continuously formed from the inflow port 20a to the buffer chamber 22 is: A waste supply passage 20 is formed so as to intersect at least a part of the area of the buffer chamber 22.
In other words, the filth supply path 20 is formed such that a virtual line parallel to the flow direction of the water flowing from the inflow port 20a to the filth supply path 20 intersects at least a part of the area of the buffer chamber 22. That is, the flow path from the inflow port 20a to the buffer chamber 22 is formed such that the washing water and the dirt passing through the inflow port 20a are directed to the buffer chamber 22.

Therefore, the washing water and the waste flowing into the waste supply passage 20 from the inflow port 20a flow toward the buffer chamber 22 in the upstream part of the waste supply passage 20. That is, the water flow that has flowed into the waste supply passage 20 from the inflow port 20a flows evenly throughout the buffer chamber 22. The washing water and the filth flowing into the buffer chamber 22 flow toward the downstream of the filth supply path 20 as they are, and flow from the outlet 20 b to the crushing unit 40.
As described above, the configuration in which the tangent line A along the flow path wall surface of the waste supply path 20 on the upstream side of the buffer chamber 22 intersects at least a part of the area of the buffer chamber 22 is a water flow forming means. Serve as a function.
In addition, also in this embodiment, the convex part 24 may be formed.

  According to the waste crushing apparatus 1 according to another embodiment of the present invention, at least one of the tangent A along the flow path wall surface of the waste supply path 20 upstream of the buffer chamber 22 and the water flow forming means is provided. Since it is configured to intersect with the region of the portion, the water flow can be more reliably directed from the inflow port 20a to the buffer chamber 22. Therefore, the accumulation of dirt in the buffer chamber 22 can be suppressed, and when the inspection port 80 is removed, the accumulation of dirt can be further suppressed.

<Modification>
The embodiments of the present invention have been described above, but the present invention is not limited to the above-described embodiments.

  For example, in the present embodiment, the configuration in which the inspection port 80 is provided in the tank lid 70 which is the upper surface of the tank body TH has been described. However, in consideration of the maintainability of the crushing unit 40, the inspection port 80 is provided in the tank body TH. It may be provided on the side of the waste supply path 20. However, considering the leakage of sewage and the like from the inspection port 80 and the storage amount of sewage in the tank body TH, the inspection port 80 is preferably provided above the filth supply path 20 of the tank body TH.

  Further, in the present embodiment, the configuration in which the projection of the projection 24 or the inflow port 20a intersects at least a part of the buffer chamber 22 is the water flow forming means. What is necessary is just to form a water flow for guiding, and for example, a concave portion or a rib may be used.

  The elements included in each of the above-described embodiments can be combined as far as technically possible, and those combinations are also included in the scope of the present invention as long as they include the features of the present invention.
