Description

  The present invention relates to a pressure-fed toilet device, and more particularly, to a pressure-fed toilet device that crushes and pumps solid matter contained in sewage discharged from a toilet body.

Conventionally, toilets for household use have been drained using the slope of the drain pipe from the toilet to the sewage, but when installing the drain pipe from the toilet to the sewage, From the toilet to the sewage due to the burden of installation work, such as peeling the floor and digging up the ground, or because the toilet space is restricted due to the layout of the house and the location of the drain pipe, and the layout cannot be freely laid A pressure-feed toilet equipped with a pressure-feed device that pumps wastewater has been developed (see, for example, Patent Document 1).
This conventional pressure-fed toilet device includes a storage tank that stores sewage discharged from the toilet body after the cleaning water is washed from the cleaning water tank to the toilet body, and in this storage tank, a crushing device and A pumping device is provided. The crushing device once captures and crushes solid matter such as sewage and toilet paper discharged from the toilet body, and the sewage containing this crushed solid is forced to the sewage side by a pumping device consisting of a pump. It is designed to be pumped to.
Further, as described in Patent Document 1, the pulverization apparatus includes a casing formed of a screen with a hole, and this casing temporarily removes solid matter contained in sewage discharged from the toilet body. It captures and allows moisture to pass through. Further, a crushing unit including a cutter for crushing the captured solid matter is provided in the casing.
When sewage containing solid matter is discharged from the toilet and flows into the casing, the water and urine pass through the holes in the screen and accumulate in the storage tank. On the other hand, the solid matter that cannot pass through the holes in the screen is captured in the screen of the casing, and is finely pulverized by a cutter of the pulverization unit so as to be large enough to pass through the holes in the screen, and then flows into the storage tank. Furthermore, the sewage containing the pulverized solid in the storage tank is sucked by the pump, discharged to the outside of the storage tank, and flows to the sewage side.
However, in the above-described conventional pulverizer, when sewage is discharged from the toilet body to the pulverizer, liquid such as water and urine in the toilet body is discharged prior to solids such as filth and toilet paper. And solids tend to be discharged later with a small amount of liquid. For this reason, when the solid matter reaches and is captured in the casing screen, most of the sewage has already passed through the holes in the screen, and most of the solid matter remains in the screen, causing the cutter to idle. There was a problem that it was not crushed.
Therefore, in order to solve such a problem, as described in Patent Document 1, when crushing solid matter in the casing, the area of the hole of the screen is adjusted as appropriate so that moisture passing through the screen is reduced. Attempts have been made to make it easy to grind solid matter while keeping water in the screen as much as possible while limiting or supplying water from the washing water tank into the screen.

However, in the above-described conventional pressure-fed toilet device, the pulverization of the solids in the pulverization unit is performed while receiving water supplied from the washing water tank, so that the solids are scattered around during the pulverization of the pulverization unit.
Also, when the cutter pulverizes solids and the pump operates, the water level of the storage tank and pulverization part falls and reaches the height of the upper and lower ends of the cutter, and when the cutter is not completely submerged, The filth adhering to the cutter scatters around, and the scattered filth accumulates on the ceiling or wall surface in the storage tank. Such accumulation of filth in the storage tank causes a bad odor and a failure of equipment such as a cutter and a pump disposed in the tank.
Furthermore, the amount of water retained in the pulverizing unit is determined by two amounts of water: the amount of water supplied by the washing water tank to the pulverizing unit and the amount of pumping by which the pump pumps dirty water. It is likely to be greatly affected by the timing and accuracy of each pumping function. For this reason, it is not possible to sufficiently guarantee the performance of whether the solid material is always pulverized at a sufficient water level with the cutter completely submerged.
For this reason, it has been a challenge to complete the pulverization of solid matter at a sufficient water level in a state where the cutter is completely submerged, and to prevent splashing and scattering of water around the cutter.

Therefore, the present invention has been made to solve the above-described problems from the prior art, and effectively pulverizes the solids contained in the sewage discharged from the toilet body and efficiently pumps the sewage. The purpose is to provide a toilet device.

A flap valve 9 is provided in the discharge port 2a of the toilet body 2, and the flap valve 9 closes the discharge port 2a until the toilet is cleaned. Further, the flap valve 9 opens the discharge port 2a for a predetermined time according to a command from the control device 6 when the toilet body 2 is washed and the sewage in the toilet body 2 is discharged to the storage tank 10. After the sewage in the toilet body 2 is discharged, it is closed.

Further, in the charts A to H, the horizontal axis is indicated by time “t”, and the numbers attached to the time t indicate the order of the steps, and the values increase in time series order.

As shown in FIG. 3, a seating detection sensor (not shown) or the like detects the seating of the user at t1, or the user turns on a remote control switch by remote control operation or the like (see chart A), and at the same time a water supply device Water supply to the toilet bowl body 2 is started from 4 and the toilet body 2 is stored (see Chart F). At this time, the water level in the storage tank 10 is substantially an intermediate water level (see chart D), the flap valve 9 is closed (see chart E), and the electric ball valve 34 is open (see chart F).
Next, detection of seating is completed at t2, or the remote control switch is turned off (see chart A), and water supply from the water supply device 4 to the toilet body 2 is stopped at t3 (see chart F).
After the user uses the toilet, when the cleaning switch for cleaning the toilet body 2 is turned on at t4 (see Chart B), the cleaning process of the toilet body 2 starts simultaneously with the toilet body 2 from the water supply device 4 Water is supplied for washing, and the toilet body 2 is washed (see Chart F). At the same time, the crushing and pressure-feeding motor 28 is operated at t4, and rotates forward at a rotational speed of, for example, about 2500 rpm (see Chart C).

Next, at t5, the cleaning switch is turned off, and at t6, the crushing and pressure feeding motor 28 is stopped (see charts B and C). Between t4 and t6, since the pump 14 is operating with the electric ball valve 34 open, the water in the storage tank 10 is pumped to the pumping path 32, and the water level in the storage tank 10 decreases. (Refer to Chart D).
Further, the flap valve 9 is opened at t7, and the sewage in the toilet body 2 is discharged from the outlet 2a of the toilet body 2 to the pulverizing section 12 in the storage tank 10 (see Chart E). Water supply from the water supply device 4 to the toilet body 2 is stopped at t8, and the flap valve is closed at t9 (see charts E and F).
Furthermore, at the time t10, additional water supply from the crushing part water supply path 4b of the water supply device 4 to the storage tank 10 is started, and at the same time, the electric ball valve 34 is closed (see charts G and H). At t11, the crushing pressure feeding motor 28 is actuated again, and rotates forward at a rotational speed of about 2500 rpm or more, and at the same time, additional water supply from the crushing part water supply path 4b to the storage tank 10 is stopped (see charts C and G). Between t7 and t11, the water level in the storage tank 10 rises and reaches the highest position at t11 (see chart D).

Further, at t14, the crushing and pressure-feeding motor 28 accelerates again to a rotational speed of about 2500 rpm or more and rotates forward at a relatively high speed, and at the same time, water supply from the water supply device 4 to the toilet body 2 is started. Water is performed (see charts C and F). Further, at t15, the crushing and pressure feeding motor 28 stops (see chart C).
In comparison with the control mode (hereinafter referred to as “rotational control mode I”, which will be described later in detail) relating to the rotation of the crushing and pressure feeding motor 28 from t11 to t15, the pump 14 is compared at about 2500 rpm or more between t11 and t13. Rotating at a relatively high rotational speed, the sewage in the storage tank 10 is pumped, and the water level in the storage tank 10 drops from the highest position to almost the middle position (see Chart D). At the same time, the cutter 22 of the crushing unit 12 rotates at a relatively high rotational speed of about 2500 rpm or more in a submerged state, and crushes most of the solid material 11 in the crushing chamber 20.
Moreover, between t13 and t14, the impeller 26 of the pump 14 rotates forward at a relatively low speed of about 1500 to 1700 rpm, and the sewage in the storage tank 10 is gently pumped. At the same time, the water level in the storage tank 10 gradually decreases from almost the middle position (see chart D) and passes through the upper and lower end positions of the cutter 22 of the crushing section 12, but the water level is changed from the cutter upper end water level to the cutter level. The cutter 22 rotates at a relatively low number of revolutions until it completely passes to the water level at the lower end of 22 (hereinafter referred to as “cutter lower end water level”).
Furthermore, between t14 and t15, the pump 14 rotates again at a relatively high rotational speed of about 2500 rpm or more, and the sewage in the storage tank 10 is further pumped, and the water level of the storage tank 10 further decreases to t15. It becomes the lowest position (see Chart D).

Next, at t16, the flap valve 9 is opened again and the electric ball valve 34 is closed. Water supply from the water supply device 4 to the toilet body 2 is stopped at t17, and the flap valve 9 is closed at t18 (see charts E and F). At t19, additional water supply from the pulverization unit water supply path 4b of the water supply device 4 to the storage tank 10 is started again (see chart G).
Next, in order to pulverize the residual solid matter in the pulverization chamber 20 that could not be pulverized in the rotation control mode I and discharge it from the storage tank 10, the pulverization / pumping motor 28 is operated again at t20, and the pressure is about 2500 rpm or more. Simultaneously with normal rotation at the number of rotations, additional water supply from the crushing part water supply path 4b to the storage tank 10 is stopped (see charts C and G).
Between t15 and t20, the water level in the storage tank 10 rises from the lowest water level at t15 to a position substantially equal to the highest water level at t11 (see Chart D).

After t20, the crushing pressure feeding motor 28 stops at t21, operates again at t22, reversely rotates at a rotational speed of about 2500 rpm or more, stops at t23, and thereafter crushing pressure feeding motor 28 from t24 to t31. Is a control mode (hereinafter referred to as “rotation control mode II”) in which forward rotation and reverse rotation are alternately and intermittently repeated at short time intervals similarly to the operation from t20 to t23 (see chart C). By the crushing and pressure-feeding motor 28 that operates in the rotation control mode II, the impeller 26 of the pump 14 and the cutter 22 of the crushing unit 12 alternate between forward rotation and reverse rotation intermittently at short time intervals from t20 to t31. Is repeated (hereinafter referred to as “intermittent alternating operation”).
Next, in order to pulverize the residual solid matter in the pulverization chamber 20 that could not be pulverized in the rotation control mode II and discharge it from the storage tank 10, the pulverization / pumping motor 28 stopped at t31 is again activated at t32. The electric ball valve 34 is opened at the same time as it operates to rotate forward at a rotational speed of about 2500 rpm or more. At t33, the crushing and feeding motor 28 decelerates to a rotational speed of about 1500 to 1700 rpm, and rotates forward at a relatively low speed (see chart C). Further, at t34, the pulverizing and pressure-feeding motor 28 accelerates again to a rotational speed of about 2500 rpm or more and rotates forward at a relatively high speed, and at t35, the pulverizing and pressure-feeding motor 28 stops (see Chart C). That is, the crushing and pressure-feeding motor 28 from t32 to t35 rotates in the same rotation control mode as the rotation control mode I described above (hereinafter referred to as “rotation control mode III”). As a result, the solid matter remaining in the crushing chamber 20 that could not be crushed in the crushing process of the crushing unit 12 by the rotation control modes I and II before t32 is further crushed by the rotation control mode III cutter 22 from t32 to t35. Pumped with a pump 14.

Between t20 and t32, the water level in the storage tank 10 gradually decreases from t20 to t32 due to gentle pumping of the pump 14 by intermittent alternating operation from t20 to t31. From t32 to t33, the impeller 26 of the pump 14 rotates forward at a rotational speed of about 2500 rpm or more and the pump 14 is pumped in earnest, and the water level in the storage tank 10 is lowered to a substantially middle position.
From t33 to t34, the impeller 26 of the pump 14 rotates forward at a relatively low speed of about 1500 to 1700 rpm, and the pump 14 is gradually pumped, and the water level in the storage tank 10 gradually decreases. From t34 to t35 Until t32 to t33, the impeller 26 of the pump 14 rotates forward at a rotational speed of about 2500 rpm or more, and the pump 14 is fully pumped, and the water level in the storage tank 10 is at the lowest position. .

Furthermore, additional water supply from the crushing part water supply path 4b of the water supply device 4 to the storage tank 10 is started again at t36, the additional water supply is stopped at t37 (see Chart G), and the sealed water reservoir of the storage tank 10 is performed. Preparation for the next series of steps is performed.
Moreover, the water level in the storage tank 10 does not change from t35 to t36, and the water level rises to a substantially middle position from t36 to t37, and the series of steps is completed.

FIG. 4 shows a mode pattern (hereinafter referred to as “mode pattern (i)”) relating to the rotational speeds of the cutter 22 and the pump 14 in the rotation control mode I corresponding to the portion from t11 to t15 in the charts C and D shown in FIG. ) And the water level change in the storage tank 10.
Hereinafter, the operation of the cutter 22 and the pump 14 and the change in the water level in the storage tank 10 in the rotation control mode I will be described in detail with reference to FIG.
As shown in FIG. 4, the crushing operation by the cutter 22 is mainly performed from t11 to t13. The water level of the storage tank 10 is in a water level section higher than the water level at the upper end of the cutter 22 (hereinafter referred to as “grinding operation water level section”), and is a time range from t11 to less than t13 (hereinafter referred to as “grinding operation time range”). When the water level sensor 30 detects a water level higher than the cutter upper end water level, for example, the cutter 22 is completely submerged in the crushing chamber 20, and is rotated forward at a crushing rotation speed N1 of, for example, about 2500 rpm or more. The crushing operation of the object 11 is performed mainly, and the crushing is almost completed. Further, in the pulverization operation time region, the pump 14 rotates at the pulverization rotational speed N1 together with the cutter 22 and pumps it, and the water level of the storage tank 10 is lowered.
After that, when the water level of the storage tank 10 detected by the water level sensor 30 reaches the cutter upper end water level and departs from the pulverization operation water level section at t13, the cutter 22 decelerates and, for example, shifts to a rotational speed of about 1500 to 1700 rpm. Silent operation is mainly performed by rotating at a rotational speed (hereinafter referred to as “transition rotational speed”) N2 smaller than the grinding rotational speed N1. In this quiet operation, the water level detected by the water level sensor 30 in the time range from t13 to less than t14 (hereinafter referred to as “silent operation time range”) is a section in which the water level is higher than the cutter cutter lower water level and lower than the cutter upper water level (hereinafter referred to as “silent operation water level”). It is continued for as long as it is in the “section”. Further, in this quiet operation time region, the pump 14 also rotates at the transition rotational speed N2 together with the cutter 22, and the water level of the storage tank 10 gradually decreases.
Thereafter, when the water level in the storage tank 10 detected by the water level sensor 30 falls below the lower end water level of the cutter and deviates from the silent operation water level section at t14, the impeller 26 of the pump 14 accelerates again and rotates at the pumping speed N3. Then, the pumping operation of the pump 14 is mainly performed, and the sewage in the storage tank 10 is pumped to the pumping path 32. This pumping operation is performed while the water level detected by the water level sensor 30 is below the lower end water level of the cutter (hereinafter referred to as “pumping operation water level section”) in a time range from t14 to less than t15 (hereinafter referred to as “pumping operation time range”). If the water level sensor 30 detects the preset minimum water level of the storage tank 10 at t15, the pump 14 stops and drainage from the storage tank 10 is completed.

According to the above-described pressure-fed toilet apparatus 1 according to the first embodiment of the present invention, when the water level sensor 30 detects a water level higher than the cutter upper end water level, the rotation control mode I of the crushing and pressure-feed motor 28 is used. The solid material 11 is mainly pulverized by rotating at high speed while the cutter 22 is completely submerged. As a result, the solid material 11 and water are mixed well and fluidity is ensured, and the pulverized solid material 11 is renewed by the buoyancy and the pulverized surface is easily crushed. It can be carried out. Moreover, since the pulverized material splashed by the centrifugal force due to the rotation of the cutter 22 collides with the vortex water wall formed in the vicinity of the rotating cutter 22 and is absorbed, it is solid in the storage tank 10 at the time of pulverization. It is possible to prevent scattering of objects.
Further, when the water level sensor 30 detects the water level from the cutter lower end water level to the cutter upper end water level, the cutter 22 rotates at a low speed by the rotation control mode I of the crushing pressure feeding motor 28. Water splash and splash can be suppressed.
Furthermore, when the water level sensor 30 detects a water level lower than the cutter lower end water level, the impeller 26 of the pump 14 rotates at a high speed by the rotation control mode I of the crushing and pressure feeding motor 28, and the water splash by the cutter 22. Therefore, the sewage in the storage tank 10 can be effectively drained without scattering.
Moreover, according to the pressure-feed type toilet apparatus 1 of this embodiment, since the crushing part water supply path 4b is provided, even if the water level in the crushing chamber 20 becomes lower than the cutter upper end water level during the crushing operation, the crushing part water supply Additional water supply is performed from the path 4b to the pulverization unit 12, and the water level in the pulverization chamber 20 at the time of pulverization becomes higher than the cutter upper end water level. As a result, the solid material 11 can be pulverized while the cutter 22 is always submerged.
Furthermore, according to the pressure-feed type toilet device 1 of the present embodiment, the pressure-feeding suppression means such as the electric ball valve 34 suppresses the amount of sewage pumped from the pump 14 until the pulverization in the pulverization unit 12 is completed, and the storage tank In order to suppress the lowering of the water level in 10, the water level in the pulverization chamber 20 at the time of pulverization can be sufficiently secured.

Further, according to the above-described pressure-feed toilet apparatus 1 of the present embodiment, after the rotation control mode I of the crushing and pressure-feeding motor 28, when additional water is supplied to the storage tank 10 and reaches the maximum water level, the rotation control mode II The cutter 22 and the pump 14 intermittently repeat forward and reverse rotation intermittently at short time intervals, and intermittent alternating operation is performed. As a result, the intermittent alternating operation can prevent the water and solids in the crushing chamber 20 from being circulated, and can effectively apply a collision force and a shearing force to the solids to improve the crushing efficiency. Moreover, since the cutter 22 and the pump 14 are stopped in a short time after the start of the swirling of the water in the storage tank 10 after starting, the kinetic energy of the water is low, and the drainage from the pump 14 is extremely unlikely to occur. Grinding efficiency can be improved without significantly reducing the water level.
Further, according to the pressure-feed type toilet apparatus 1 of the present embodiment, the pulverization is performed in the pulverization process of the pulverization unit 12 in the rotation control modes I and II by the rotation control mode III after the rotation control mode II of the pulverization and pressure-feed motor 28. The solid matter remaining in the crushing chamber 20 that could not be removed can be reliably crushed and discharged.
Moreover, according to the pressure-feed type toilet apparatus 1 of this embodiment, the crushing completion detection device 36 can detect that the crushing of the solid material 11 by the cutter 22 of the crushing unit 12 has been completed, and the amount and quality of the solid material can be detected. Even in the case where the time required for pulverization varies depending on the conditions, the water level in the pulverization chamber 20 can be set to an appropriate water level for pulverization, or the pulverization pressure feeding motor 28 can be appropriately controlled.

In the above-described pressure-fed toilet device 1 according to the present embodiment, the rotation control mode of the crushing and pressure-feeding motor 28 has been described as a combination of the three types of rotation control modes I, II, and III shown in FIG. However, the patterns of each mode are not limited to those described above, and any pattern can be set as long as the crushing is completed and the pumping is performed at a water level higher than the cutter top water level during crushing. can do.
In the following, some typical examples of mode patterns applicable to the rotation control modes I and / or III will be described as mode patterns other than the mode pattern (i) described above.

Next, FIG. 5 shows a mode pattern (hereinafter referred to as “mode pattern (ii)”) of a first modification applicable to the rotation control modes I and / or III of the pressure-feed toilet apparatus according to the first embodiment of the present invention. 5 is a diagram similar to FIG.
As shown in FIG. 5, the mode pattern (ii) is characterized in that the pulverization speed N1 from t11 to t13 (pulverization operation time range) is larger than the pumping speed N3 from t14 to t15 (pressure feed operation time range). Other than this feature, the feature is the same as the feature of the mode pattern (i) described in FIG.
According to the mode pattern (mode pattern (ii)) of the first modification applicable to the rotation control modes I and / or III of the pressure-fed toilet device according to the first embodiment of the present invention, the cutter 22 can be used in the pulverization operation time range. Rotates at a higher speed than the mode pattern (i), so that the pulverization can be performed in a shorter time. Further, while the water level is lowered from the cutter upper end water level to the cutter lower end water level, the cutter 22 rotates at a low speed and a silent operation is performed, so that splashing and scattering of water in the storage tank 10 can be prevented.

Next, FIG. 6 shows a mode pattern (hereinafter referred to as “mode pattern (iii)”) of a second modification applicable to the rotation control modes I and / or III of the pressure-fitted toilet apparatus according to the first embodiment of the present invention. FIG. 6 is a view similar to FIG. 4 and FIG.
As shown in FIG. 6, in the mode pattern (iii), when the cutter 22 rotates at the crushing rotation speed N1 at t11 and the water level sensor 30 detects the cutter upper end water level at t13, the cutter 22 is temporarily stopped. . In the time range from t11 to less than t13 (hereinafter referred to as “turning operation time range”), solids are pulverized mainly.
After t13, until the water level sensor 30 detects the lower water level of the cutter, the cutter 22 intermittently repeats the operation of turning and stopping at intervals of Δt for a short time with the grinding rotation speed N1 as the maximum rotation speed. An operation in which turning is suppressed (hereinafter referred to as “turning suppression operation”) is performed.
In the time range from t13 to less than t14 in which the turning restraining operation is performed (hereinafter referred to as “turning restraining operation time region”), the cutter 22 turns with the pulverization rotational speed N1 as the maximum rotational speed, but makes a short turn at Δt intervals. Therefore, similar to the silent operation of the cutter 22 described with reference to FIG. 4, the operation is substantially the same as the continuous operation in which the cutter 22 rotates at a low speed.
After that, when the water level of the storage tank 10 detected by the water level sensor 30 at t14 falls below the lower end water level of the cutter and deviates from the quiet operation water level section (see FIG. 6), it is in the pumping operation water level section (see FIG. 6). The 14 impellers 26 rotate at a pumping speed N3 smaller than the grinding speed N1, the pumping operation of the pump 14 is mainly performed, and the sewage in the storage tank 10 is pumped to the pumping path 32. When the water level sensor 30 detects the preset minimum water level of the storage tank 10 at t15, the pump 14 stops and the drainage from the storage tank 10 is completed.

According to the mode pattern (mode pattern (iii)) of the second modification that can be applied to the rotation control modes I and / or III of the pressure-fed toilet device according to the first embodiment of the present invention described above, the turning suppression operation time range Thus, the cutter 22 turns with the grinding rotation speed N1 as the maximum rotation speed, but with a short time interval Δt. For this reason, like the silent operation of the cutter 22 described in FIG. 4, the operation is the same as the continuous operation in which the cutter 22 rotates at a substantially low speed, and water splashing and scattering around the cutter 22 during pulverization are suppressed. it can.
Further, while the impeller 26 of the pump 14 is also operated together with the cutter 22 during the turning restraining operation, the start and stop of the cutter 22 are repeated in the pulverization chamber 20 in a time during which no effective vortex can be generated for drainage. As a result, the circulation of water and solids in the crushing chamber 20 can also be prevented, the kinetic energy of the water during the swiveling suppression operation is low, drainage from the pump 14 is very unlikely, and the water level is not significantly reduced, The grinding efficiency can be improved.

FIG. 7 shows a mode pattern (hereinafter referred to as “mode pattern (iv)”) of a third modification applicable to the rotation control modes I and / or III of the pressure-fed toilet device according to the first embodiment of the present invention. It is a figure similar to FIGS. 4-6.
As shown in FIG. 7, in mode pattern (iv), at t11, the cutter 22 and the impeller 26 of the pump 14 rotate at the crushing rotation speed −N1, that is, reversely rotate at the crushing rotation speed N1. At this time, since the pump 14 mainly performs the pressure feeding function only during the forward rotation of the impeller 26, the pump 14 hardly performs the pressure feeding, the grinding operation by the cutter 22 is mainly performed, and the water level gradually decreases.
When the water level sensor 30 detects the cutter upper end water level at t13, after the cutter 22 and the impeller 26 are temporarily stopped, the cutter 22 and the impeller 26 are crushed at the rotation speed N1 until t14 when the water level sensor 30 detects the cutter lower end water level. A quiet operation is performed by rotating at a low speed at a lower pumping speed N2 and the sewage in the storage tank 10 is gently pumped.
After that, when the water level of the storage tank 10 detected by the water level sensor 30 falls below the cutter lower end water level at t14 and deviates from the silent operation water level section (see FIG. 7) and is in the pumping operation water level section (see FIG. 7), the pump The 14 impellers 26 rotate at a pumping speed N3 larger than the pumping speed N2, the pumping operation of the pump 14 is mainly performed, and the sewage in the storage tank 10 is pumped to the pumping path 32. When the water level sensor 30 detects the preset minimum water level of the storage tank 10 at t15, the pump 14 stops and the drainage from the storage tank 10 is completed.

  According to the mode pattern (mode pattern (iv)) of the third modification applicable to the rotation control modes I and / or III of the pressure-fed toilet device according to the first embodiment of the present invention described above, it is between t11 and less than t13. In the pulverization operation time range (see FIG. 7), almost no pumping is performed by the pump 14, the water level is not significantly lowered, and the pulverization efficiency can be improved.

FIG. 8 is a cross-sectional view similar to FIG. 2 showing a pressure-fed toilet device according to the second embodiment of the present invention. Here, in FIG. 8, the same parts as those in FIG. 2 are denoted by the same reference numerals, and description thereof will be omitted.
As shown in FIG. 8, in the pressure toilet apparatus 40 according to the second embodiment of the present invention, the cutter 22 of the crushing unit 12 and the impeller 26 of the pump 14 provided in the storage tank 10 of the solid material crushing and feeding apparatus 48. The respective rotations are independently controlled by driving the crushing motor 28a and the pressure feeding motor 28b. The driving of the crushing motor 28a and the pressure feeding motor 28b is performed by the information from the water level sensor 30 and the crushing completion detecting device 36 as in the case of the pressure feeding toilet apparatus according to the first to fourth embodiments of the present invention described above. Based on the above, it is variably controlled by the control device 6.
Also, a series of sequences of the pressure-fed toilet device 40 according to the present embodiment is the same as the sequence shown in FIG. 3 except for the mode pattern of the rotation control mode I and / or III shown in FIG. Description of the portion will be omitted, and the mode pattern of this embodiment corresponding to the mode pattern of the rotation control mode I and / or III shown in FIG. 3 will be described.

FIG. 9 shows a mode pattern (hereinafter referred to as “mode pattern (v)”) relating to the rotational speeds of the cutter 22 and the pump 14 of the pressure-fed toilet device 40 according to the second embodiment of the present invention and the water level change in the storage tank. FIG. Here, in FIG. 9, the upper graph shows the relationship between the cutter rotational speed and time, the middle graph shows the relationship between the pump rotational speed (impeller rotational speed) and time, and the lower graph shows the storage. The relationship between the water level in the tank and time is shown.
As shown in FIG. 9, in the mode pattern (v), the crushing motor 28a (see FIG. 8) rotates forward at t11, and the cutter 22 rotates at high speed at the crushing rotation speed N1, and the solid material 11 is crushed. . When the water level in the storage tank 10 detected by the water level sensor 30 at t13 reaches the cutter upper end water level and deviates from the crushing operation water level section, the cutter 22 decelerates and rotates at a crushing rotation speed N2 smaller than the crushing rotation speed N1. Then, the silent cutter operation is performed. Thereafter, when the water level of the storage tank 10 detected by the water level sensor 30 falls below the cutter lower end water level and deviates from the cutter silent operation water level section at t14, the cutter 22 stops.
On the other hand, with respect to the pump 14, the tapping motor 28b (see FIG. 8) rotates forward independently of the crushing motor 28a at t11 ′ within the pulverization operation time range from t11 to less than t13, and the impeller 26 rotates at the pumping speed N3. And the pump 14 is pumped. After that, when the water level sensor 30 detects the preset minimum water level of the storage tank 10 at t15, the pump 14 is stopped and the drainage from the storage tank 10 is completed.
As described above, according to the pressure-feed toilet apparatus 40 and the mode pattern (v) according to the second embodiment of the present invention, the crushing operation by the cutter 22 is performed based on the water level in the storage tank 10 detected by the water level sensor 30. In addition, the pumping operation by the pump 14 can be controlled independently, and the pulverization and the pumping can be performed effectively and effectively while preventing the water splashing and scattering around the cutter 22.
In addition, in this embodiment mentioned above, as shown in FIG. 8, although the form provided with the crushing part water supply path 4b and the electric ball valve 34 was demonstrated, according to the pressure-feed type toilet apparatus 40 of this embodiment, at the time of a grinding | pulverization Since the pump 14 is stopped and only the cutter 22 is driven, it is possible to suppress the lowering of the water level of the crushing unit 12, and therefore, the crushing unit water supply path 4 b and the electric ball valve 34 may be omitted.

FIG. 10 shows a mode pattern (hereinafter, referred to as “mode pattern (vi)”) of a modified example relating to the rotational speeds of the cutter and pump of the pressure-fed toilet device according to the second embodiment of the present invention and the water level change in the storage tank. It is a figure similar to FIG.
As shown in FIG. 10, in the mode pattern (vi), from t11 to t13, the crushing motor 28a (see FIG. 8) intermittently performs forward and reverse rotations at short intervals with the crushing rotation speed N1 as the maximum rotation speed. Repeatedly, the grinding operation is performed. When the water level in the storage tank 10 detected by the water level sensor 30 at t13 reaches the cutter upper end water level and deviates from the crushing operation water level section, the cutter 22 decelerates and rotates at a crushing rotation speed N2 smaller than the crushing rotation speed N1. Then, the silent cutter operation is performed. Thereafter, when the water level of the storage tank 10 detected by the water level sensor 30 falls below the cutter lower end water level and deviates from the cutter silent operation water level section at t14, the cutter 22 stops.
On the other hand, for the pump 14, the pumping motor 28b (see FIG. 8) rotates forward at the pumping speed N3 independently of the crushing motor 28a at t11 ′, and the pump 14 is pumped.
After that, when the water level sensor 30 detects the preset minimum water level of the storage tank 10 at t15, the pump 14 is stopped and the drainage from the storage tank 10 is completed.
As described above, according to the mode pattern (vi) of the modified example related to the rotational speed of the cutter and pump of the pressure-fitted toilet apparatus 40 according to the second embodiment of the present invention, the water level in the storage tank 10 detected by the water level sensor 30 Therefore, the crushing operation by the cutter 22 and the pumping operation by the pump 14 can be controlled independently, and the crushing and the pumping can be effectively performed well while preventing water splashing and splashing. Furthermore, at the time of crushing, the crushing operation in which the forward rotation and the reverse rotation are intermittently repeated at short time intervals can prevent the water and the solid matter in the crushing chamber 20 from being circulated. Effectively acting, the grinding efficiency can be improved.

  Further, the solid material pulverized by the pulverization unit 12 passes through the hole 16 of the pulverization unit 12 and is sucked and pumped and drained by the pump 14. Since the solid matter after pulverization can be reduced by such improvement in pulverization efficiency, the size of the holes 16 can be reduced. That is, since the risk of clogging of the pipe can be reduced, the pressure feed path 32 can be made thinner. By setting the size of the hole 16 to 10 to 15 mm, a flexible pipe having an inner diameter of 15 to 20 mm can be suitably used as the pressure feeding path 32.

FIG. 11: is a schematic block diagram which shows the pumping toilet apparatus 1 by the 3rd Embodiment of this invention. FIG. 12 is a partial plan sectional view showing a pressure-feed toilet apparatus according to the third embodiment of the present invention. Here, in FIG.11 and FIG.12, the same code | symbol is attached | subjected to the part same as FIG. 1, and those description is abbreviate | omitted.
As shown in FIGS. 11 and 12, the pulverization section water supply channel 4 b is disposed in the storage tank 10. The water in this crushing part water supply path 4b is additionally supplied into a water conduit 52 formed between the toilet outlet 2a and the screen 18 of the crushing part 12. Further, the water supply port 54 of the pulverization unit water supply path 4 b is arranged at the upper part of the solid material pulverization pump 8 and directed to the pulverization unit 12, and water is discharged from the water supply port 54 toward the pulverization unit 12. It is like that.

Furthermore, a flow sensor 56 that detects the amount of water supply (instantaneous flow rate and integrated flow rate) is connected to the upstream side of the water supply device 4 of the pressure-feed toilet device 51 according to the present embodiment. Based on the amount of water supplied by the flow sensor 56, the control device 6 controls the opening / closing and switching of the toilet water supply channel 4 a and the crushing unit water supply channel 4 b of the water supply device 4 and the driving of the flap valve 9. That is, based on the detection signal of the flow sensor 56, the toilet water supply amount can be made constant regardless of the water supply pressure. Further, the water level in the storage tank 10 can be converted, and the control device 6 can execute the same control as in the first embodiment of the present invention.
Further, the control device 6 can complement each other and control the water supply amount detected by the flow sensor 56 and the water level information detected by the water level sensor 30 so that each operation unit can be controlled more safely and accurately. It has become. As the flow sensor 56, an electromagnetic type, an impeller type, a float type, a Kalman type, an ultrasonic type, or the like is used.
Furthermore, the pressure-feed toilet apparatus 51 according to the present embodiment includes an electrode switch 58 that detects an abnormal water level in the storage tank 10. The electrode switch 58 is detected when the pump 14 or the water supply device 4 or the flow sensor 56 or the water level sensor 30 becomes abnormal and the water level in the storage tank 10 continues to rise and reaches a predetermined abnormal water level. It is set to be. When these abnormalities are detected, the function of the pressure-fed toilet device 1 can be safely stopped and the abnormality can be notified to the user.

Next, the contents of control executed by the control device for the pressure-fitting toilet apparatus according to the present embodiment will be described with reference to FIGS.
Charts A to I in FIG. 13 show an example of a sequence in the pressure-feed toilet apparatus 51 according to the present embodiment. In addition, in each sequence of FIG. 13, since the sequence other than the sequence related to water supply is common with the sequence of the pressure-feed toilet apparatus 1 of the first embodiment shown in FIG. 3, the description of the sequence of this common part is omitted. Only the sequence related to water supply will be described.
FIG. 14 is a schematic diagram illustrating an example of a sequence of an initial diagnosis mode in the pressure-fed toilet apparatus according to the present embodiment.
As shown in FIG. 14, when the power supply of the pressure-fitting toilet apparatus 1 is turned on at t0 as a stage before the sequence shown in FIG. 13 starts, initial diagnosis of each functional unit is started. In this initial diagnosis, the flap valve 9 is first opened and closed (see chart E), then the pump 14 is driven (see chart C), and then the toilet water supply path 4a of the water supply device 4 is opened.

Next, the flow of diagnosis of the flow sensor 56 and the water level sensor 30 in the above-described initial diagnosis mode will be described.
After the initialization operation of the water level sensor 30, the control device 6 sets the crushing part water supply path 4 b of the water supply device 4 to the water-flowing state, and the control device 6 performs the integrated flow rate (I) based on the detection signal of the flow sensor 56. ) Is controlled so as to stop water supply at the time (t04) when it reaches a predetermined value (see Chart I).
At t04, the control device 6 diagnoses whether the water level in the storage tank (D) is equal to or higher than the reference value (see chart D).
Further, at t03 to t04, the control device 6 diagnoses whether the instantaneous flow rate (J) is equal to or higher than the reference value based on the detection signal of the flow sensor 56 (see chart J).

  In the above-described initial diagnosis mode, if any diagnosis result is NG, the control device 6 safely stops the pressure-feed type toilet device 51 as a device abnormality and notifies the abnormality.

  Further, as shown in FIG. 13, when seating is detected at t1 or the remote control switch is turned on (see chart A), water supply from the water supply device 4 to the toilet body 2 is started, and the detection signal of the flow sensor 56 is displayed. When the integrated integrated flow rate (I) reaches a predetermined amount, the toilet water supply (F) is stopped (see chart F).

Next, after the user uses the toilet, the cleaning switch for cleaning the toilet body 2 is turned on at t4 (see chart B). At the same time, the cleaning process of the toilet body 2 starts, and the water supply device 4 starts. Water is supplied to the toilet body 2 for cleaning, and the inside of the toilet body 2 is cleaned (see Chart F).
Next, the flap valve 9 is opened at t7, the sewage in the toilet body 2 is discharged from the outlet 2a of the toilet body 2 to the pulverization section 12 in the storage tank 10 (see chart E), and the water level sensor 30 is in the storage tank. An increase in the water level (D) is detected (see chart D).

Next, when the integrated flow rate (I) based on the detection signal of the flow sensor 56 reaches a predetermined amount, water supply from the water supply device 4 to the toilet body 2 is stopped at t8 and the water channel of the water supply device 4 is switched, and at t10. The additional water supply to the pulverization unit 12 is started.
