A first embodiment embodying the toilet apparatus 100 of the present disclosure will be described with reference to the drawings. In the following description, regarding the vertical direction, the positive direction of the Z-axis shown in FIG. 1 is the upward direction, and the negative direction of the Z-axis is the downward direction. Regarding the horizontal direction, the positive direction of the Y-axis shown in FIG. 1 is the left direction, and the negative direction of the Y-axis is the right direction. Regarding the front-rear direction, the positive direction of the X-axis shown in FIG. 1 is the forward direction, and the negative direction of the X-axis is the rearward direction. Specifically, the front-back direction, the left-right direction, and the up-down direction refer to the front-back direction, the left-right direction, and the up-down direction, respectively, when viewed from a seated person sitting on a toilet seat (not shown).

The toilet apparatus 100 is installed in a toilet room R, for example, as shown in FIG. The toilet room R is provided in a house, a vehicle, or the like. The toilet device 100 includes a toilet bowl 10, a buffer tank 11, a crushing section 12, a conveying pump 13, a drain tank 14, a water supply tank 15, a water supply pump 16, and a control section 70, as shown in FIG. The toilet bowl 10 has a toilet bowl 10A, a water guide portion 10B, and a connection member 30. As shown in FIG. The toilet bowl 10A has a bowl shape that is open upward. A discharge port 10M, which is an opening penetrating vertically, is formed at the lower end of the toilet bowl 10A. The discharge port 10M has a substantially circular shape when viewed from above (see FIG. 3).

The water guide portion 10B is provided at the rear upper end portion of the toilet bowl 10 and behind the toilet bowl 10A. One end of the water conduit 10E is connected to the rear portion of the water conduit 10B. The other end of the water conduit 10E is connected to communicate with a water supply pump 16, which will be described later. A water outlet 10F communicating with the toilet bowl 10A is formed through the front end of the water guide portion 10B. A toilet seat and a toilet lid (not shown) are attached to the toilet bowl 10 .

The connection member 30 is connected to communicate with the discharge port 10M of the toilet bowl 10A. The connecting member 30 has a substantially cylindrical shape, and is connected so that the upper end opening covers the outer peripheral surface of the discharge port 10M. The connection member 30 has a packing 30A, a flapper valve 30B, and a support member 30C, as shown in FIG. The packing 30A is made of rubber, for example, and has a cylindrical shape. One open end of the packing 30A is in contact with the outlet 10M of the toilet bowl 10A so as to communicate therewith.

The flapper valve 30B has a flat plate shape over the entire circumference. The support member 30C is generally L-shaped. A rotating shaft portion 30E is provided at a position where the long side and the short side of the supporting member 30C are connected, and the supporting member 30C is rotatably supported around the rotating shaft portion 30E. The tip of the long side extending laterally is connected to the flapper valve 30B so as to support the flapper valve 30B. One end of the extension coil spring 30G is locked to the lower end of the short side extending downwardly. The other end of the tension coil spring 30G is connected to the outer surface of the connection member 30. As shown in FIG. A lower end portion of the support member 30C on the short side is pulled by a tension coil spring 30G in a direction in which the long side is lifted upward. Thus, the flapper valve 30B closes the open lower end of the packing 30A by the pulling force of the tension coil spring 30G, thereby maintaining the closed state of the discharge port 10M. The flapper valve 30B and the packing 30A close the discharge port 10M, thereby suppressing the flow of the odor below the flapper valve 30B to the toilet room R side. The spring constant of the tension coil spring 30G, the length dimension of the long side of the support member 30C, and the length dimension of the short side of the support member 30C are determined so that the flapper valve 30B descends when a predetermined amount of flush water is stored in the toilet bowl 10A. It is set so that the discharge port 10M can be opened by pressing.

One end of the operating shaft 30D is connected to the lower end of the supporting member 30C on the side of the short side extending downwardly. The operating shaft 30D has a rod shape elongated in one direction. For example, as shown in FIG. 2, the other end of the operating shaft 30D is connected to the lower end of the lifting shaft 30H via a connecting member 30F provided below the water guide portion 10B. The pull-up shaft 30H has a rod shape elongated in one direction. An upper end portion of the lifting shaft 30H is connected to an operation portion 10C provided above the toilet bowl 10 . The operation unit 10C is, for example, a so-called lever that is gripped and rotated by the user.

When the operating portion 10C is operated, the lifting shaft 30H is pulled up, and the operating shaft 30D moves backward via the connecting member 30F. As a result, the lower end on the short side of the hanging supporting member 30C is pulled backward, the supporting member 30C and the flapper valve 30B rotate around the rotary shaft 30E, and the end on the long side of the supporting member 30C and Flapper valve 30B moves downward (see FIG. 4). Thus, the flapper valve 30B is separated from the packing 30A to open the discharge port 10M.

When the operation of the operating portion 10C is stopped, the lifting shaft 30H descends and the operating shaft 30D moves forward. Along with this, the support member 30C and the flapper valve 30B rotate around the rotary shaft 30E due to the tensile force of the tension coil spring 30G, and the end of the long side of the support member 30C and the flapper valve 30B move upward. Thus, the flapper valve 30B closes the open lower end of the packing 30A, thereby closing the discharge port 10M (see FIG. 4). Flapper valve 30B thus opens and closes outlet 10M.

An operation detection unit 10D is provided in the operation unit 10C. For example, a known microswitch or the like is used for the operation detection unit 10D. The operation detection section 10D is electrically connected to the control section 70, which will be described later. When the operation detection unit 10D detects that the operation unit 10C has been operated (i.e., rotated), it outputs an operation detection signal D to the control unit 70, and the operation detection unit 10D outputs an operation detection signal D to the control unit 70. not), the operation detection signal D is not output.

As shown in FIG. 4, the buffer tank 11 has a tubular shape with an open upper end 11A and a closed lower end 11B. The toilet bowl 10 is installed on the installation surface F. The buffer tank 11 is arranged so as to penetrate the installation surface F in the vertical direction. Specifically, the upper portion of the buffer tank 11 protrudes above the installation surface F, and the lower portion is arranged below the installation surface F. As shown in FIG. The front side of the buffer tank 11 is curved rearward from the top to the bottom. The opened upper end 11A of the buffer tank 11 is connected to the lower end opening of the connecting member 30 so as to communicate therewith. That is, the upper end 11A of the buffer tank 11 is connected to the discharge port 10M via the connecting member 30. As shown in FIG. The buffer tank 11 is provided below the flapper valve 30B. The lower end of the buffer tank 11 attached to the toilet bowl 10 is slightly downwardly inclined rearward. The rear side of the lower end portion of the buffer tank 11 is open rearward. The lower end of the buffer tank 11 may be inclined downward when attached to the toilet bowl 10, and the lower end of the buffer tank 11 before being attached to the toilet bowl 10 does not need to be inclined downward.

The pulverizing section 12 has a pulverizing cylindrical section 12E with both ends opened, a rotating shaft 12A extending in the front-rear direction, and pulverizing blades 12B connected to the rotating shaft 12A. One open end of the pulverization tube portion 12E is connected to an opening formed in the rear side of the lower end portion of the buffer tank 11 so as to communicate therewith. One end of the pulverizing tube portion 12E is an inlet 12C of the pulverizing portion 12 . The inlet 12</b>C communicates with the rear side of the side surfaces below the upper end 11</b>A of the buffer tank 11 . That is, the pulverizing unit 12 is connected to the buffer tank 11 so as to communicate with the rear side of the buffer tank 11 below the upper end 11A of the buffer tank 11 . The side surface here includes the right side surface, the left side surface, and the front side surface of the buffer tank 11 . The rotating shaft 12A is arranged coaxially with the pulverizing cylinder portion 12E.

The crushing blade 12B includes a plate portion 12F extending perpendicularly to the rotating shaft 12A and two crushing blades 12D formed by cutting and raising both ends of the plate portion 12F sandwiching the rotating shaft 12A toward the inside of the buffer tank 11. , (see FIG. 5). The tip of the crushing blade 12D (end edge on the buffer tank 11 side) protrudes into the buffer tank 11 more than one end of the crushing cylindrical portion 12E. That is, the tip portion (the edge on the buffer tank 11 side) of the crushing blade 12D of the crushing blade 12B is arranged inside the buffer tank 11 . The tip of the crushing blade 12D is located behind the discharge port 10M.

The conveying pump 13 has a conveying tube portion 13E with both ends opened, a rotating shaft 13A extending in the front-rear direction, and an impeller 13B connected to the rotating shaft 13A. One open end of the conveying tube portion 13E communicates with and is connected to the other open end of the crushing tube portion 12E. The rotating shaft 13A is arranged coaxially with the conveying tube portion 13E. The tip of the rotary shaft 13A of the conveying pump 13 and the rear end of the rotary shaft 12A of the pulverizing section 12 are coaxially connected. The rotating shaft 13A of the conveying pump 13 and the rotating shaft 12A of the crushing section 12 are coaxial. A transport opening 13C is formed in the transport tube portion 13E. A conveying path 14A is connected to the conveying port 13C. The impeller 13B has a disk 13F perpendicular to the rotating shaft 13A and a plurality of blades 13G extending radially from the rotating shaft 13A (see FIG. 5).

A motor M is arranged behind the conveying pump 13 . The tip of the drive shaft S of the motor M is connected to the rear end of the rotating shaft 13A. The motor M is electrically connected to the controller 70 (see FIG. 2). The operation of the motor M is controlled by the controller 70 . A rotational force generated by the motor M is transmitted through the drive shaft S to the rotating shafts 13A and 12A. As a result, the rotating shaft 13A, the impeller 13B, the rotating shaft 12A, and the crushing blades 12B rotate integrally. The crushing unit 12, the conveying pump 13, and the motor M are arranged below the installation surface F. As shown in FIG.

When the impeller 13B rotates, the sewage Sew stored in the buffer tank 11 (hereinafter also referred to simply as the sewage Sew) is sucked into the inlet 12C, and solids contained in the sewage Sew approach the crushing blades 12D of the crushing section 12. pulverized. The sewage Sew includes washing water, urine, feces, toilet paper, and the like. Among them, stool, toilet paper, etc. are solids contained in the sewage Sew, and wash water and urine are water contained in the sewage Sew. The pulverized solid matter is conveyed to the conveying path 14A via the crushing section 12 and the conveying port 13C of the conveying pump 13 together with water contained in the sewage Sew. Since it is not necessary to consider that the solid matter flows into the conveying path 14A without being pulverized, the inner diameter of the conveying path 14A can be reduced. In this way, the conveying pump 13 flows the solid material pulverized in the pulverizing section 12 toward the conveying port 13C and further conveys it to the downstream conveying path 14A. The rotating shaft 12A, the rotating shaft 13A, and the drive shaft S of the motor M are slightly downwardly inclined rearward when the pulverizing unit 12 is attached to the buffer tank 11 attached to the toilet bowl 10 .

As shown in FIG. 3 , the buffer tank 11 , crushing unit 12 , conveying pump 13 , and motor M are arranged inside the outer edge of the toilet bowl 10 in plan view from above. Specifically, all of the buffer tank 11, all of the pulverizing section 12, all of the conveying pump 13, and at least part of the motor M are positioned inside the outer edge of the toilet bowl 10A in plan view from above. are placed in Since the buffer tank 11 and the toilet bowl 10</b>A have such a positional relationship, sewage in the toilet bowl 10</b>A can immediately flow into the buffer tank 11 .

For example, when the operation unit 10C is operated once and the washing water for washing the toilet bowl 10A flows into the buffer tank 11, the crushing unit 12, and the conveying pump 13, the inflow port 12C of the crushing unit 12 is submerged. (see Figure 4). At this time, the inflow port 12C of the pulverizing section 12 is positioned below the water surface Ws1 of the wash water that has flowed into the buffer tank 11 (see FIG. 4). In other words, the inflow port 12C communicates with the buffer tank 11 at a position where the buffer tank 11 is submerged in a state where the buffer tank 11 stores flush water for one wash of the toilet bowl 10A. Since the sewage Sew is washing water plus sewage (urine, feces, toilet paper, etc.), the amount of sewage Sew is greater than the amount of washing water for washing the toilet bowl 10A once. Therefore, when the sewage Sew flows into the buffer tank 11, the water surface Ws2 becomes higher than the water surface Ws1 when the washing water for one wash of the toilet bowl 10A flows into the buffer tank 11. Inlet 12C is submerged deeper. That is, the inflow port 12C of the pulverizing unit 12 is positioned below the water surface Ws2 of the sewage Sew that has flowed into the buffer tank 11 (see FIG. 4).

The drain tank 14 is connected and communicated with a transfer port 13C of the transfer pump 13 via a transfer path 14A. As shown in FIGS. 1 and 3, the drain tank 14 is arranged in the toilet room R behind the toilet bowl 10 and behind the partition wall W rising behind the toilet bowl 10 . A shelf board B, for example, is arranged at the upper end of the partition wall W (see FIG. 1). The drain tank 14 is arranged within the range of the frontage dimension Fd when the toilet room R in which the toilet bowl 10 is arranged is viewed from the front of the toilet bowl 10 (see FIG. 3). The upper end T of the drain tank 14 is arranged at a position higher than the position P of the flapper valve 30B (see FIG. 2).

The water supply tank 15 stores wash water for washing the toilet bowl 10A. The water supply tank 15 is arranged behind the toilet bowl 10 and behind the partition wall W in the toilet room R. The water supply tank 15 is arranged within the range of the frontage dimension Fd when the toilet room R in which the toilet bowl 10 is arranged is viewed from the front of the toilet bowl 10 (see FIG. 3). That is, both the drain tank 14 and the water supply tank 15 are arranged within the range of the frontage dimension Fd when the toilet room R in which the toilet bowl 10 is arranged is viewed from the front of the toilet bowl 10 (see FIG. 3).

The water supply pump 16 is provided above the water supply tank 15 . The water supply pump 16 is arranged in the toilet room R behind the toilet bowl 10 and behind the partition wall W rising behind the toilet bowl 10 . The water supply pump 16 pumps up the wash water stored in the water supply tank 15 and supplies it to the toilet bowl 10A via the water conduit 10E, the water conduit 10B, and the water outlet 10F.

The control unit 70 is, for example, mainly composed of a microcomputer, and includes an arithmetic unit such as a CPU (Central Processing Unit), a memory such as a ROM (Read Only Memory) or a RAM (Random Access Memory), and an A/D converter. etc. For example, when the operation detection signal D is input once from the operation detection unit 10D, the control unit 70 has a function of rotating the motor M for a predetermined time and then stopping the operation of the motor M (Fig. 2). The control unit 70 has a function of operating the water supply pump 16 and supplying a predetermined amount of flushing water from the water supply tank 15 to the toilet bowl 10A when the operation detection signal D is input once from the operation detection unit 10D. (See Figure 2). The predetermined amount is, for example, 1 liter. This predetermined amount (1 liter) is the minimum amount of wash water for one time that is considered to be necessary for washing the waste from the toilet bowl 10A and crushing it in the crushing section 12 .

An example of the operation of the toilet device 100 will be described.

The user operates the operation section 10C once. Specifically, the user grips the operation portion 10C, twists the operation portion 10C so as to rotate it by a predetermined angle, and then releases the operation portion 10C. Then, the operation unit 10C returns to its original posture. Thus, the operation detection section 10D outputs the operation detection signal D to the control section 70 once. Based on the operation detection signal D, the control unit 70 causes the water supply pump 16 to pump up a predetermined amount of flushing water (1 liter) from the water supply tank 15 and supply it to the toilet bowl 10A.

When the user grasps the operation portion 10C and twists the operation portion 10C to rotate it by a predetermined angle, the short side of the support member 30C is pulled rearward via the pull-up shaft 30H, the connecting member 30F, and the operation shaft 30D. . As a result, the supporting member 30C and the flapper valve 30B rotate around the rotating shaft 30E, the long side end of the supporting member 30C and the flapper valve 30B move downward, and the discharge port 10M is opened. In other words, the flapper valve 30B is lowered to open the discharge port 10M at the same time as flushing water is supplied to the toilet bowl 10A or at an arbitrary timing (see FIG. 4).

Then, dirt in the toilet bowl 10A passes through the discharge port 10M and drops directly into the buffer tank 11 together with a predetermined amount of flushing water. When a predetermined amount of wash water and dirt drops into the buffer tank 11, the flapper valve 30B immediately rises to block the lower end of the packing 30A and close the discharge port 10M. Flapper valve 30B thus opens and closes outlet 10M.

Based on the input of the operation detection signal D, the control unit 70 causes the motor M to start rotating. When the motor M starts rotating, the drive shaft S of the motor M, the rotating shaft 13A, the rotating shaft 12A, the impeller 13B, and the crushing blade 12D also start rotating.

When the sewage Sew (predetermined amount of wash water and waste) flows into the buffer tank 11, the inflow port 12C of the pulverizing unit 12 communicating with the buffer tank 11 is submerged in the sewage Sew (see FIG. 4). Specifically, the upper end of the inlet 12C of the pulverizing unit 12 is positioned below the water surface Ws2 of the sewage Sew in the buffer tank 11 . Along with this, the conveying pump 13 and the motor M are also positioned below the water surface Ws2 of the sewage Sew in the buffer tank 11 .

The sewage Sew that has flowed into the buffer tank 11 is sucked into the inlet 12C of the pulverizing section 12 by the rotation of the impeller 13B and flows toward the transfer port 13C. At this time, the solid matter (filth) contained in the sewage Sew is pulverized by contact with the rotating pulverizing blade 12D, and together with the moisture (wash water and urine) contained in the sewage Sew, the pulverization unit 12, the conveying pump 13, and the It is conveyed to the drain tank 14 via the port 13C and the conveying path 14A.

After the sewage Sew in the buffer tank 11 is conveyed to the drain tank 14, the controller 70 stops the motor M from rotating. That is, the control unit 70 causes the motor M to stop rotating after being driven to rotate for a predetermined time.

According to the embodiment configured as described above, the following effects are obtained.

The toilet device 100 includes a toilet bowl 10 , a buffer tank 11 and a crushing section 12 . The toilet bowl 10 has a toilet bowl 10A having an open bottom end and a discharge port 10M, and a flapper valve 30B for opening and closing the discharge port 10M. The buffer tank 11 is provided below the flapper valve 30B. The crushing unit 12 has an inflow port 12C communicated with a rear side surface of the buffer tank 11 below the upper end 11A of the buffer tank 11 when connected to the toilet bowl 10, and crushes solids contained in the sewage Sew stored in the buffer tank 11. crush things.

According to this configuration, the buffer tank 11 is provided below the flapper valve 30B, and the pulverizing section 12 communicates with the rear side surface of the buffer tank 11 through the inflow port 12C. , and the pulverizing section 12 can be arranged closer to each other. Therefore, it is easy to make the toilet device 100 compact.

The buffer tank 11 of the toilet device 100 stores waste in the toilet bowl 10A that directly drops into the buffer tank 11 through the outlet 10M. According to this configuration, the solid matter contained in the sewage Sew passes through the discharge port 10M of the toilet bowl 10A and directly drops into the buffer tank 11, so it is possible to prevent the solid matter from accumulating on the way. . For this reason, since washing water for conveying the solid matter that remains in the middle is not required, the solid matter contained in the sewage Sew can be conveyed into the buffer tank 11 with a small amount of washing water.

The upper end 11A of the buffer tank 11 of the toilet device 100 is connected to the discharge port 10M via the connecting member 30, and the pulverizing section 12 communicates with the buffer tank 11 below the upper end 11A of the buffer tank 11. According to this configuration, since the pulverizing section 12 is connected to the buffer tank 11 below the upper end 11A of the buffer tank 11, the solids contained in the sewage Sew stored in the buffer tank 11 flow from the inlet 12C to the pulverizing section. It becomes easy to flow into 12.

The crushing unit 12 of the toilet device 100 is connected to the buffer tank 11 on the rear side. According to this configuration, the pulverizing section 12 can be brought closer to the flow path such as the conveying path 14A which tends to be provided behind the toilet bowl 10, so that the waste pulverized in the pulverizing section 12 can be easily discharged toward the flow path. .

The toilet device 100 includes a conveying pump 13 that communicates with the downstream side of the crushing section 12 and conveys the solid matter crushed in the crushing section 12 further downstream. According to this configuration, the pulverized solid matter can be transported to a desired location regardless of the height of the desired location.

The rotating shaft 12A of the crushing unit 12 of the toilet device 100 and the rotating shaft 13A of the conveying pump 13 are coaxial. According to this configuration, the toilet device 100 can be made small, and the single motor M can drive the pulverizing section 12 and the conveying pump 13 .

The toilet device 100 includes a drain tank 14 that communicates with the downstream side of the conveying pump 13, and the upper end of the drain tank 14 is positioned higher than the flapper valve 30B. According to this configuration, the position of the toilet device 100 can be easily lowered regardless of the size of the drain tank 14 . For example, when the toilet device 100 is installed in a vehicle, the drain tank 14 does not have to be installed under the floor of the vehicle, and the floor of the vehicle can be easily lowered.

The toilet apparatus 100 includes a water supply tank 15 that stores flush water for cleaning the toilet bowl 10A. 10 is arranged within the range of the frontage dimension Fd when viewed from the front. According to this configuration, the water supply tank 15 and the drainage tank 14 can be made invisible to the user, and the toilet apparatus 100 can be made smaller.

The toilet device 100 has the buffer tank 11 and the pulverizing portion 12 located inside the outer edge of the toilet bowl 10 in plan view from above. According to this configuration, the buffer tank 11 and the crushing section 12 can be arranged directly below the toilet bowl 10 , thereby shortening the flow path connecting the buffer tank 11 and the crushing section 12 . For this reason, it is possible to suppress the occurrence of a situation in which solids contained in the sewage Sew stored in the buffer tank 11 remain in this flow path and are not pulverized by the pulverizing unit 12, and pulverize the solids satisfactorily. be able to. Along with this, it is possible to smoothly discharge sewage from the toilet bowl 10A to the buffer tank 11. - 特許庁

The inflow port 12C of the toilet device 100 communicates with the buffer tank 11 at a position where the buffer tank 11 is submerged in a state in which flush water for washing the toilet bowl 10A is stored once. According to this configuration, the inflow port 12C of the crushing unit 12 is submerged every time the toilet bowl 10A is washed once. The solid matter contained in can be satisfactorily pulverized.

The crushing unit 12 of the toilet device 100 has a rotating crushing blade 12B, and the edge of the crushing blade 12B on the buffer tank 11 side is arranged inside the buffer tank 11 . According to this configuration, the solids contained in the sewage Sew in the buffer tank 11 can be easily brought into contact with the crushing blades 12B, so that the solids can be satisfactorily crushed. Furthermore, since the pulverizing blades 12B are arranged in the buffer tank 11 without interposing a flow path between the buffer tank 11 and the pulverizing section 12, the solid matter stays in the flow path and clogs the flow path. situation can be avoided.

(2) Unlike the first embodiment, the pulverizing unit may be configured to be driven when the inlet is blocked by the wash water for washing the toilet bowl. In this case, for example, when the water level sensor detects that the water surface of the sewage is positioned above the upper end of the inlet, it is conceivable to output a water level detection signal to the control unit to rotate the motor. . According to this configuration, the pulverizing section can satisfactorily pulverize the solids contained in the sewage without idling.
(3) Unlike the first embodiment, the control unit may rotate the motor after the operation detection signal is input from the operation detection unit a plurality of times. In other words, the motor may be rotationally driven to drive the pulverizing unit when the buffer tank has accumulated a plurality of times of sewage.
