Description

  The present invention relates to a flush toilet, and particularly relates to a flush toilet with a pressure-feeding / drainage function having a high degree of freedom in construction of drainage piping.

2. Description of the Related Art Conventionally, there has been proposed a flushing device system for flush toilets in which a pressure feeding device is installed below the floor and a toilet body is installed on the floor. (For example, Patent Document 1)
JP 2002-364050 A (page 4-5, FIGS. 1 and 2)

Patent document 1 is demonstrated based on the following figure.
6 and 7 are diagrams for explaining the technology of the pressure feeding system related to a conventional faucet, FIG. 6 is a schematic side view of a conventional pressure feeding device system, and FIG. 7 is an exploded perspective view thereof.
6 and FIG. 7, the pressure feeding device system 111 includes a tank 11, a toilet bowl 12, a wall drainage flush toilet 110, an inflow pipe 27, a cylindrical portion 24, and a storage tank 25. And consist of A pump impeller 21, a cutter 22, and a motor 23 are disposed in the storage tank 25. Wastewater mixed with filth that has entered from the inlet 26 is pulverized by the cutter 22 in the storage tank 25, and pumped together with the manure accumulated at the bottom of the storage tank 25 by the pump impeller 21 from the drain pipe 28. The toilet 12 and the pressure feeding device 20 are connected at the toilet drain 43 of the drain pipe 14 and the inlet 26 of the inflow pipe 27 through which the drainage flows. The toilet 12 is placed on the toilet placing part 15, and the storage tank 25 of the pressure feeding device 20 is placed on the placing part 30. The placement unit 30 is fixed to the floor surface 40 via a fixing unit 31, and has an attachment / detachment unit 32 with the toilet bowl placement unit 15.

  Next, a description will be given based on the cleaning operation. By operating an operation unit (not shown), the wash water in the tank 11 is supplied to the toilet 12. Then, a siphon action is generated in the toilet 12 and drained from the toilet drain 43 of the drain pipe 14 toward the pressure feeding device 20. In the pressure feeding device 20, the drainage proceeds in the order of the inflow pipe 27, the cylindrical portion 24, and the storage tank 25. In the storage tank 25, the filth is crushed by the above-described cutter 22 and is pumped to the outside through the drain pipe 28.

  Next, it demonstrates based on a construction method. A placement unit 30 for placing the pressure feeding device 20 is installed in an opening on the rear side floor surface of the space where the wall drainage flush toilet 110 is installed, and the pressure feeding device 20 is placed on the placement unit 30. Then, a drainage pipe 28 serving as a path for drainage discharged from the pressure feeding device 20 is connected to the pressure feeding device 20, and the toilet drainage 43 of the wall drain type flush toilet 110 and the inlet 26 which is the drainage inlet of the pressure feeding device 20 are connected. Connect. In addition, the attachment / detachment part 32 of the mounting part 30 and the toilet bowl mounting part 15 are connected before connection. Therefore, the mounting portion 30 on which the pressure feeding device 20 is mounted is provided below the floor surface 40. Therefore, when connecting the toilet drain port 43 of the wall-drainage flush toilet 110 and the pumping apparatus 20, the pumping apparatus itself is stabilized, so that workability is greatly improved. Moreover, since the toilet 12 and the pumping apparatus 20 are connected by adjusting the two components of the mounting part 30 and the pumping apparatus 20, the flexibility of the workability in the height direction is improved. Furthermore, a toilet placing part 15 is provided at the lower part of the toilet 12. Therefore, it becomes easier to adjust the alignment of the inlet 26 of the pressure feeder 20 and the toilet drain 43 of the toilet 12 by aligning a plurality of thicknesses of the toilet placing part 15. Also, regarding the installation of the toilet bowl 12 by detaching it from the mounting portion 30, the construction position can be confirmed simultaneously with the pressure feeding device 20, so that it is not necessary to prepare for the construction for the toilet bowl 12 and the workability is improved. In addition, since there is the fixing portion 31 of the mounting portion 30 on the floor surface 40, the workability further increases without moving the mounting portion 30 itself when something is connected to the pressure feeding device 20, etc. Even when there is some vibration, it is possible to ensure the connection between the toilet 12 and the pressure feeding device 20 with certainty. Moreover, it becomes very easy to remove also at the time of removal. Further, as an effect, the placement portion 30 can be continuously formed on the floor surface 40, and the design is improved and the opening portion is not shown on the floor surface 40, so that there is no possibility that foreign matter will fall below the floor. Safety is improved. In FIG. 2, the placing portion and the toilet placing portion are joined via the attaching / detaching portion. However, if they are formed integrally in advance, it is possible to save the trouble of wearing and further improve the workability. Moreover, by changing the fixing location of the mounting part 30 in various ways, it is possible to easily connect the pressure feeding device to a toilet having various drainage cores without changing the construction method itself.

However, even in the pumping device having such an excellent effect, it is necessary to generate siphons enough to increase the toilet's washing and discharging capacity, and the toilet drain line has a long vertical portion, and the final toilet The outlet was close to the floor. When installing with a pumping device under the toilet outlet, the floor surface is opened and the pumping device is installed under the toilet. There was a problem that the connection work between the surface opening and the toilet outlet and the inlet of the pressure feeding device was also poor.
In addition, when installing the pressure feeding device behind the toilet, the installation space is necessarily long in the depth direction of the toilet space.
In addition, there is a problem in that the design is poor when a separate pumping device is installed behind the toilet bowl.

  The present invention has been made to solve such problems, and in a toilet having a function of pumping drainage with a high degree of freedom in drainage pipe handling, it improves workability and further saves space. It aims at improving design properties.

  In order to achieve the above object, a first aspect of the present invention stores a toilet bowl that discharges wastewater from a filth, a toilet outlet that discharges wastewater in the toilet, and wastewater that is discharged from the toilet outlet. In a toilet with a pressure drainage function comprising a storage tank disposed on the floor and a pump for crushing and pumping the waste water in the storage tank, the toilet outlet is connected to the upper surface of the storage tank, and the inside of the storage tank, A drain socket is provided that communicates with the toilet outlet and has a vertical portion for enhancing siphoning.

  The invention according to claim 2 is characterized in that the toilet outlet and the drain socket are hermetically connected.

  In the invention according to claim 3, the pump includes a motor unit, a pulverization chamber for pulverizing solid filth, and a pump chamber for pumping sewage wastewater. The drain socket arranged in the upper part of the pump chamber and communicated with the toilet discharge port is arranged in communication with the intake port of the crushing chamber.

  In the invention according to claim 4, in the toilet bowl, a storage part for storing the storage tank and the pump is provided at the lower part of the toilet bowl, and the storage tank and the pump stored in the storage part are concealed by a separate cover part. It is characterized by that.

  In the invention which concerns on Claim 5, the mounting part which mounts the said storage tank and the said pump was provided, and the said mounting part was fixed to the said toilet bowl, It is characterized by the above-mentioned.

According to the first aspect of the present invention, the storage tank can be disposed not in the rear of the toilet but in the lower part of the toilet discharge port by connecting the toilet discharge port from the upper surface of the storage tank. Thereby, the size of the depth side of the whole toilet bowl with a pressure drainage function can be made small.
Moreover, since a pumping apparatus can be accommodated in a toilet bowl, since a toilet bowl and a pumping apparatus become an integral structure instead of a separate structure, the designability improves.
In addition, with regard to the cleaning and discharging performance of filth from the toilet, even if the storage tank is placed on the floor by connecting a drain socket having a vertical portion inside the storage tank in communication with the toilet outlet, Since the height difference of the toilet discharge line can be sufficiently taken from the discharge port to the lower end of the vertical part of the drain socket, even when the storage tank is placed on the floor, the siphon action can be sufficiently generated, It can be discharged. Also, in the installation work of the toilet with a pressure drainage function, it is easy to assemble, pack, and transfer in the factory because of the integrated configuration in which the pressure feeder is housed inside the toilet. Furthermore, since the trouble of connecting the toilet bowl and the pressure feeding device can be saved at the site, it is only necessary to install the toilet bowl with a pressure feeding / drainage function and connect the water supply / drainage, so that the workability is greatly improved.

  In the invention according to claim 2, by connecting the toilet outlet and the drain socket in a sealed state, in the siphon phenomenon, it is possible to prevent siphon force from being weakened due to drainage leaking from the connection portion. Further, it is possible to prevent the siphon force from being weakened by entraining air in the middle of the pipeline due to the influence of the displacement of the pipeline due to the vibration caused by the flow of dirt and the like.

  In the invention which concerns on Claim 3, since the motor part is arrange | positioned at the upper part of a pump and the crushing chamber is arrange | positioned in the low position of the pump below a motor part, the position of the inlet_port | entrance of the crushing chamber connected with a drain socket Therefore, the vertical part of the drain socket can be made longer. That is, since the height difference of the toilet discharge pipe can be made longer, the siphon effect can be enhanced and the cleaning performance of the toilet can be improved.

  In the invention which concerns on Claim 4, it looks good by concealing the toilet outlet, the storage tank, and the pump with a separate cover part having a design integral with the toilet bowl part. Further, when maintaining the connecting portion of the toilet outlet and the storage tank, the storage tank and the pump, the maintenance workability is improved because the cover can be removed.

  In the invention which concerns on Claim 5, a storage tank and a pump can be mounted in a mounting part, respectively, and can be fixed to a toilet bowl. By adopting this structure, the positional relationship between the respective parts can be stably maintained. Therefore, even when a toilet with a pressure drainage function is lifted to move, an unreasonable force does not act on the connecting portion between the storage tank and the toilet outlet, and a structure without breakage or disconnection of the connecting portion can be obtained. .

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic overall cross-sectional view of a toilet with a pressure / drainage function according to the first embodiment of the present invention, and FIG. 2 is a schematic cross-sectional view of a storage tank portion of the toilet with the pressure / drainage function. As shown in FIGS. 1 and 2, the toilet discharge path 42 that continues from the bowl portion 41 has a shape that rises once and then descends so that the bowl portion 41 can be sealed with water. A toilet discharge port 43 corresponding to the lower end of the toilet discharge path 42 is connected to the storage tank 25 from the upper surface 62 of the storage tank via a connection packing 44. By adopting such a configuration, the storage tank 25 can be accommodated and disposed substantially below the toilet discharge path 42, that is, inside the toilet with a pressure drainage function.

When a cleaning operation unit (not shown) is operated, the water supply valve 53 is opened and the cleaning water is discharged from the rim water discharge port 54 and the jet water discharge port 55. In the initial stage of the cleaning operation, the cleaning water is discharged from the rim spout 54, and the bowl 41 is cleaned and the water level rises. Next, discharged water is ejected from the jet outlet 55 toward the pipe direction of the toilet discharge path 43, and the filth is discharged by the siphon action. Finally, a series of cleaning operations are completed by recovering the accumulated water in the bowl portion 41 that has been reduced by the siphon action by discharging water from the rim spouting port 54 again. Next, the wastewater discharged from the toilet outlet 43 passes through the drain socket 45 and is conveyed to the crushing chamber 48 of the pump 49. On the other hand, the sensor 52 senses that the water level of the storage tank 25 has reached a specified water level due to drainage, and is pulverized by rotating the cutter 22 by the motor 23 and is discharged from the small hole 56 to the bottom of the storage tank 25. . In the pump chamber 47 at the bottom of the pump 49, the discharged filth-related waste water is similarly rotated by the motor 23 to rotate the pump impeller 21 through the internal pressure feed pipe 57 and the pressure feed drain pipe 58 outside the storage tank 25. The sensor 52 detects that the water level has fallen below the specified water level, stops the motor 23, and completes a series of pumping and draining operations. Thus, in a toilet with a pressure-feeding / drainage function, the drainage after washing can be pumped with a pump, and a degree of freedom can be obtained in the construction and handling of the drainage pipe.
As described above in detail, the flushing and discharging ability of a toilet with a pressure-feeding / draining function is accompanied by a siphon action, and the time and strength of the siphon action greatly affect the flushing and discharging ability of the toilet bowl.
