Description

  The present invention relates generally to a toilet device, and more particularly, to a drainage socket for draining a wall for draining toilet waste to the wall side, and a toilet device having the drainage socket.

  In recent years, there has been an increasing demand for downsizing of toilet devices. In this case, it is important to maintain drainage performance. The drainage performance depends on the siphon force, which is the force to flow filth, and the shape of the flow path, which is the ease of filth flow. Since the siphon phenomenon uses the difference in potential energy between the water storage position and the water discharge position, the height h that is the difference in height in the Z direction of the drainage channel 210 of the toilet shown in FIG. The height of the drainage channel 210 inlet opening upper end and the drainage channel lower end) determines the siphoning force. The greater the height h, the greater the siphon power. On the other hand, in order to reduce the size of the toilet device 200, it is necessary to reduce the total length L in the X direction from the wall surface W to the distal end 203 of the toilet 202, which is currently about 800 mm. Here, FIG. 8A is a cross-sectional view of the conventional wall drainage toilet device 200 described in FIG.

  For wall drainage, a drainage socket 220 that can be attached to and detached from the drainage channel 210 is used. The drain socket 220 has a support part 222 and connection parts 224 and 226. Since the height J from the floor surface FL to the center line of the drainage pipe D provided on the wall surface W varies in the range of 100 mm to 155 mm, the support portion 222 is configured to have a variable height in the Z direction. The outlet end of the toilet drainage channel 210 is inserted into the connecting part 224, and the connecting part 226 is inserted into the inlet end of the drainage pipe D. The filth is drained from the toilet 202 to the drainage pipe D through the drainage channel 210 and the connecting portions 224 and 226. At this time, the drain socket 220 converts the direction in which filth flows by 90 ° in the drain channel 225. In the drain socket 220, it is necessary to reduce the length A ′ in the X direction from the wall surface W of the drain socket 220 shown in FIG. Here, FIG. 8B is an enlarged cross-sectional view of the drain socket 220 of FIG. 8A described in FIG.

There exists patent document 2 as another prior art.
Japanese Patent Laying-Open No. 2005-48407 (FIGS. 11, 28, and 29) JP-A-8-260551

Patent Document 1 discloses a flow path whose bottom point is the lower end 227 of the outlet of the connection portion 226 in FIG. However, when the height J increases, the amount of insertion of the outlet end portion of the drainage channel 210 into the connection portion 224 increases. As a result, the end face 212 of the outlet end of the drainage channel 210, the distance _{J 1} between the drain passage 225 directly below the end surface 212 is reduced. If the distance J ₁ is less dirt it is hardly rotated 90 °, as a result, flowability is decreased. Patent Document 1 proposes to provide an extended portion 228 with an R in FIG. 28 and FIG. 29 and a lowest point 229 protruding from the lower end 227 of the connecting portion 226. Accordingly, the distance J ₁ is flowability is improved to increase. However, since the publication does not examine in detail the shape of the flow path 225 including the expansion part 228, the drainage performance is not necessarily sufficient, and in particular, the shape of the flow path 225 suitable for making the toilet device 200 small. The setting method becomes a problem.

  Therefore, an object of the present invention is to provide a toilet device that maintains drainage performance.

  The toilet device according to one aspect of the present invention includes a first connection portion into which an outlet end portion of a drainage channel of a toilet bowl is inserted, and an inlet end portion of a drainage pipe provided on a wall surface, so that the first connection is made. And a drainage channel provided between the first connection portion and the second connection portion and projecting downward from the second connection portion. And a drain socket having the outlet, and is determined by a distance between a position closest to the wall surface of the lower end of the outlet of the second connection portion and a position closest to the wall surface of the lower end of the outlet end portion, The minimum cross-sectional area of the drainage channel is made larger than the cross-sectional area of the outlet end portion of the drainage channel. In such a toilet device, the minimum cross-sectional area of the drainage channel is made larger than the cross-sectional area of the outlet end of the drainage channel, so that the ease of flow is improved.

  The outlet end has a diameter of 53 mm to 60 mm, and the distance is preferably 62 mm or more. In this case, it was confirmed that the residue and clogging of filth were improved.

  The drainage channel has a spherical projecting portion having a center eccentric to the wall surface side from the center line of the outlet end of the drainage channel, the drain pipe has an inner diameter of 75 mm, and the wall surface The distance A ′ between the center of the outlet end and the center line is 65 mm to 115 mm, and the amount of eccentricity E in the direction perpendicular to the wall surface at the center of the overhang is preferably 10 mm to 18 mm. Due to the eccentricity, the direction of the filth is directed to the drain outlet side to facilitate movement of the filth. By setting the distance A 'to be 65 mm or more, a space for the filth to rotate by 90 [deg.] Is secured and the flowability is secured. By setting the distance A 'to 115 mm or less, the toilet device can be reduced in size. Moreover, by setting the amount of eccentricity E to 1 mm or more, the direction of the filth is directed to the drain outlet side to facilitate the movement of the filth. By setting the amount of eccentricity E to 18 mm or less, the angle from the deepest part of the drainage flow path to the second connection part is abruptly prevented so that filth stays in the overhanging part, thereby ensuring the ease of flow.

  Further, a length H in a direction perpendicular to the floor surface at which the outlet end portion of the drainage channel is inserted into the first connection portion is 20 mm to 60 mm, and the first end from the outlet end portion of the drainage channel is The distance B in the direction perpendicular to the floor surface from the lower end of the outlet of the connecting portion 2 to the plane parallel to the floor surface is preferably 50 mm to 90 mm. By setting the distance H to 64 mm or more, a siphon force is secured and a seal failure is prevented. By setting the distance H to 90 mm or less, the outlet end portion 14 a of the drain trap pipe 14 is prevented from always contacting the drainage accumulated in the drainage channel 66. Further, by setting the distance B to 90 mm or less, the siphon force is secured and clogging of filth is prevented. By setting the distance B to 50 mm or more, it is possible to prevent the outlet end of the drainage channel from always contacting the drainage accumulated in the drainage channel.

  An angle D formed by a straight line connecting the deepest portion of the drainage channel and a position closest to the wall surface at the lower end of the outlet of the second connection portion and a plane parallel to the floor surface is 1 ° to 25 °. The distance A ′ between the wall surface and the center line of the outlet end is preferably 65 mm to 115 mm. By setting the angle D to 1 ° or more, a space for the filth to rotate by 90 ° is secured, and the flowability is secured. By setting the angle D to 25 ° or less, the depth of the overhanging portion is increased and the filth is prevented from staying in the overhanging portion, and the ease of flow of the filth is ensured. By setting the distance A 'to be 65 mm or more, a space for the filth to rotate by 90 [deg.] Is secured and the flowability is secured. By setting the distance A 'to 115 mm or less, the toilet device can be reduced in size.

  The drain socket includes a drain socket body having the first connection portion, the second connection portion, and the drain passage, and a support portion that is disposed on the floor surface and supports the drain socket body. And a height adjusting means for adjusting the height of the drain socket body so that the inlet end portion of the drain pipe and the second connection portion have substantially the same height. In such a variable drainage socket, the above-mentioned problem occurs when the height of the drainage pipe is high, and therefore the present invention is particularly effective.

  A drainage socket according to one aspect of the present invention is provided on a wall of a drainage pipe having an inner diameter of 53 mm to 60 mm and an inlet end of a drainage pipe having an inner diameter of 75 mm. A second connecting portion that is insertable and opens in a direction perpendicular to the first connecting portion; and provided between the first connecting portion and the second connecting portion; A drain socket body having a drain channel extending downward, a support section disposed on the floor surface and supporting the drain socket body, the inlet end of the drain pipe, and the second connection section, A drainage socket having a height adjusting means for adjusting the height of the drainage socket body so that the drainage socket main body has substantially the same height, wherein the drainage channel is more than the center line of the outlet end of the drainage channel. Spherical bulge having a center eccentric to the wall surface side And the amount of eccentricity in the direction perpendicular to the end surface at the center of the projecting portion is 10 mm to 18 mm, and the end surface of the second connection portion on the first connection portion side and the first connection portion The distance in the direction perpendicular to the end face with respect to the center line is 65 mm to 115 mm. Such a drain socket facilitates the movement of the filth by causing the direction of the filth to be directed toward the drain port due to eccentricity. By setting the distance A 'to be 65 mm or more, a space for the filth to rotate by 90 [deg.] Is secured and the flowability is secured. By setting the distance A 'to 115 mm or less, the toilet device can be reduced in size. Further, by setting the amount of eccentricity E to 1 mm or more, the waste water is retained and the movement of the filth is facilitated. By setting the amount of eccentricity E to 18 mm or less, the angle from the deepest part of the drainage flow path to the second connection part is abruptly prevented so that filth stays in the overhanging part, thereby ensuring the ease of flow.

  An angle D formed by a straight line connecting the deepest portion of the drainage channel and a position closest to the wall surface of the lower end of the outlet of the second connection portion and a plane parallel to the end surface of the first connection portion is It is preferably 10 ° to 25 °. By setting the angle D to be 10 ° or more, a space for the filth to rotate by 90 ° is secured to ensure the ease of flow. By setting the angle D to 25 ° or less, the depth of the overhanging portion is increased and the filth is prevented from staying in the overhanging portion, and the ease of flow of the filth is ensured. The distance (B + H) in the direction perpendicular to the end surface from the end surface on the drainage channel side of the first connection portion to the plane parallel to the end surface through the lower end of the outlet of the second connection portion is 70 mm to 150 mm. It is preferable that the outlet end portion of the drainage channel can be inserted into the first connection portion by a distance H of 20 mm to 60 mm in a direction perpendicular to the end face. Siphon power and ease of flow can be ensured under these numerical conditions.

  Further objects and other features of the present invention will become apparent from the preferred embodiments described below with reference to the accompanying drawings.

  ADVANTAGE OF THE INVENTION According to this invention, the toilet device which maintained the drainage performance in a wall drain socket can be provided.

  Hereinafter, a toilet apparatus 100 according to an embodiment of the present invention will be described with reference to FIG. Here, FIG. 1 is a block diagram of the toilet device 100. The toilet device 100 includes a toilet 1, a cleaning unit 50 that cleans the toilet 1, and a drain socket 60.

  The toilet bowl 1 is a flush toilet bowl, and as shown in FIG. 1, covers a toilet main body 2 having a bowl portion 12 for receiving filth inside, a toilet seat (not shown) disposed on the main body 2, and the toilet seat. And a local cleaning device disposed in the upper rear part of the main body 2. In the toilet device 100, the length L in the X direction from the wall surface W and the distal end 3 of the main body 2 farthest from the wall surface W of the toilet device 1 is 750 mm or less, which is smaller than the conventional 800 mm. In order to achieve such a small toilet device 100, a drain socket 60 described later is particularly effective. Furthermore, for the downsizing, the height N of the seating surface of the toilet 1 is preferably 370 mm to 390 mm. When the height N is 370 mm or less, there is a risk that the user will receive water splash, and when the height N is higher than 390 mm, ease of use and downsizing are hindered.

  The cleaning unit 50 performs rim cleaning (or bowl cleaning), toilet bowl cleaning, and stored water supply. In the rim cleaning, the rim 13 that is the edge of the bowl portion 12 is cleaned. In toilet bowl cleaning, the bottom of the rim 13 of the bowl portion 12 is washed, and the filth and stored water in the bowl portion 12 are drained from the drainage pipe D using a siphon phenomenon. The stored water supply supplies the bowl 12 with stored water that prevents odors from sewage from flowing into the toilet bowl.

  The cleaning unit 50 includes a water supply system, a rim cleaning / reserved water supply system, a toilet cleaning system, and a control unit 40.

  The water supply system is directly connected to a water pipe that supplies cleaning water, and switches water supply to the toilet cleaning system and water supply to the rim cleaning / reserved water supply system via a switching valve 28.

  The rim cleaning / reserved water supply system discharges cleaning water from the rim port 18 by water supply pressure to perform rim cleaning and stored water supply. The rim cleaning / reserved water supply system uses a path (rim water supply path 18a) that does not pass through the pump 34, which is different from a water path (cleaning water pipe line 33b) that passes through the pump 34 described later.

  The toilet cleaning system performs toilet cleaning by generating a siphon phenomenon by the pump 34. The toilet flushing system includes a drain trap pipe (drainage path) 14, a jet port 16, a tank 32, and a pump 34.

  The drain trap pipe 14 has an S shape that descends from the bottom of the bowl part 12 and extends downward, and is a part where a siphon phenomenon occurs. The outlet end portion 14 a of the drain trap pipe 14 is inserted into the drain socket 60. The jet port 16 ejects water and supplies stored water necessary to generate a siphon phenomenon. The jet port 16 is formed at the bottom of the bowl portion 12 and discharges a large volume of water toward the inlet of the drain trap pipe 14.

  The tank 32 stores water necessary for the occurrence of the siphon phenomenon. The tank 32 of this embodiment has an internal volume of 3 liters or less (about 2.5 liters to 3 liters). The pump 34 pressurizes the water stored in the tank 32 and discharges it from the jet port 16. The pump 34 is disposed below the full water position L6 of the tank 32, and water is supplied to the pump 34 when the tank 32 is full. The outlet of the pump 34 is connected to the jet port 16 at the bottom of the bowl portion 12 through a washing water pipe 34b.

  The full water position L6 in the tank 32 can be set higher than the stored water position L7 in the bowl portion 12. In the present embodiment, the height from the floor surface FL of the accumulated water position L7 is 120 mm to 125 mm. If the height of the reservoir position L7 from the floor surface FL is lower than 120 mm, it takes time for the siphon, and if it is higher than 125 mm, the user may receive a change.

  The cleaning unit 50 employs a siphon-zette type that forcibly causes a siphon phenomenon by ejecting water from the jet port 16 in the toilet cleaning. In order to cause siphon phenomenon by using a pump 34 that can supply cleaning water with a large flow rate of 60 liters / minute to 120 liters / minute by increasing the diameter of the jet port 16, a drain trap pipe 14 is provided. The siphon phenomenon can be generated immediately after filling up quickly. In addition to this, when the siphon is blown out, the water is continuously supplied so that the upper end of the drain trap pipe 14 does not flow in from the upper end of the drain trap pipe 14 at the end of the siphon phenomenon. The amount of air is reduced to reduce noise when the siphon is out.

  The cleaning unit 50 includes the tank 32, and the size of the tank 32 is reduced to the same size as that of the tankless type by suppressing the capacity of the tank 32 to about 3 liters or less. The present inventors have discovered that 5.5 liters of water is required for cleaning the toilet 1, and that the minimum amount of water that causes siphoning is 3 liters. Also, 2.5 liters of water used for rim cleaning can maintain the cleaning effect even when the water pressure is low. For this reason, the water in the tank 32 is not used for the rim cleaning by separating the rim water supply path 18a which is the path of the rim cleaning / pumped water supply system from the cleaning water pipe 33b which is the path using the pump 34. did. As a result, the tank 32 does not need to store water for rim cleaning / reservoir supply, and its capacity is set to a capacity for storing only cleaning water for toilet cleaning, that is, a capacity of 3 liters required for siphoning. Can do. By reducing the capacity of the tank 32, the toilet device 100 can be downsized. Note that the amount of water to be stored in the tank 32 is less than 3 liters (for example, 2.5 liters), thereby further reducing the size of the toilet device 100, and simultaneously supplying water to the tank 32 when cleaning the toilet bowl. 3 liters may be secured. Thus, the siphon-jet type toilet device 100 using the pump 34 is suitable for downsizing.

  The control unit 40 includes a CPU that controls the operation of each unit based on information input to an operation unit (not shown) and information stored in a memory (not shown).

  The drain socket 60 communicates the outlet end portion of the drain trap pipe 14 of the toilet 1 with the inlet end portion of the drain pipe D provided on the wall surface W, and converts the direction in which filth flows by 90 ° in the drain channel 66. It has a function. The drain socket 60 includes a drain socket body 61, a support portion 70, and a height adjusting unit 76.

As shown in FIGS. 2A and 2B, the height of the drain socket body 61 can be adjusted by a height adjusting means 76 described later. Here, FIG. 2A shows a drain socket whose height is adjusted to 120 mm when the height J from the floor surface FL to the center line D ₂ of the inlet end D ₁ of the drain pipe D is 120 mm. 60 states are shown. FIG. 2B shows a state of the drain socket 60 whose height is adjusted in accordance with the height J of 155 mm.

  The height J is designed to take any of the reference heights of 100 mm, 120 mm, 148 mm, and 155 mm within the range of 100 mm to 155 mm. However, there are variations of several millimeters due to construction errors at each reference height. The drainage socket 60 can correspond to a height J in the range of 120 mm to 155 mm by the height adjusting means 76 of the present embodiment. The height adjustment may not necessarily correspond to all of 100 mm to 155 mm, and may correspond to 100 to 120 mm.

Figure 2 (a) Comparing FIG. 2 (b), the can from the floor surface FL to the center line D ₂ height enters the interior of the drain trap pipe 14 is deeper drainage socket body 61 in the case of 155mm Understood. As the drain trap pipe 14 enters the interior of the drain socket body 61 deeper, the drain passage in the drain socket body 61 becomes narrower and the ease of flow decreases. In other words, if the predetermined drainage performance is secured when the upper limit height J of height adjustment is 155 mm, the predetermined drainage performance is secured when the height J is 120 mm. For this reason, below, the structure for ensuring drainage performance when height J is 155 mm is examined. As described above, the case where the height J is 155 mm due to construction errors may be referred to as the height J of 150 mm or more in the present application.

  As shown in FIG. 3, the drain socket body 61 includes connecting portions 62 and 64 and a drain passage 65. The drain socket body 61 is made of vinyl chloride or other resin. Thus, in this embodiment, the drain socket 60 is a resin socket separate from the drain trap pipe 14, but it does not prevent the drain socket 60 from being an earthenware socket integrated with the drain trap pipe 14.

  The connecting portion (first connecting portion) 62 has an annular shape, and the outlet end portion 14 a of the drain trap pipe 14 of the toilet 1 is inserted into the connecting portion 62. An inflow port 63 that opens in the Z direction is formed in the connection portion 62 inside the ring. The Z direction is a vertical direction parallel to the wall surface W and perpendicular to the floor surface F. The diameter F of the outlet end portion 14a is set to 53 mm to 60 mm. The JIS standard requires a diameter of 50.8 mm for the diameter F, so it is set to 53 mm or more with a margin. This is because if the diameter F is larger than 60 mm, the diameter of the inlet 63 of the connecting portion 62 must be increased, and the start-up of the siphon phenomenon of the drain socket 60 is delayed, and the residue of dirt is generated.

  The length H in the X direction in which the outlet end portion 14a of the drain trap pipe 14 is inserted into the connection portion 62 (the insertion length of the pottery portion into the drain socket) is 20 mm to 60 mm. The X direction is a direction perpendicular to the wall surface W and parallel to the floor surface FL. By setting the distance H to 20 mm or more, a siphon force is secured and a seal failure is prevented. By setting the distance H to 60 mm or less, the outlet end portion 14 a of the drain trap pipe 14 is prevented from always contacting the drainage accumulated in the drainage channel 66.

The outer end surface 64a of the connecting portion 64, the distance A between the center line _{M 1} of the outlet end 14a of the inlet port 63 or the drain trap pipe 14 of the connecting portion 62 is set to 100mm to 150 mm. Distance between the end face 64b or wall W and the center line _{M 1} inside the connecting portion 64 A 'is set to 65mm to 115 mm. By setting the distance A to 100 mm or more, or setting the distance A ′ to 65 mm or more, a space for the filth to rotate by 90 ° is ensured to ensure ease of flow. By setting the distance A to 150 mm or less and the distance A ′ to 115 mm or less, the toilet device 100 can be reduced in size.

Connection (second connection portion) 64 has an annular shape, is inserted into the inlet end D ₁ of the drain pipe D which is provided on the wall surface W. In the connection portion 64, an outlet 65 that opens in the X direction is formed inside the ring. Diameter of the inlet end _{D 1} of the drain pipe D, in the present embodiment, it is 75 mm. The distance G is wastewater and an outlet 65 located closest to the wall surface W of the lower end 65a of the (end) 65a ₁ and closest to the wall surface W of the lower end 14b of the outlet end portion 14a (end portion) 14b ₁ of the connecting portion 64 The minimum cross-sectional area of the channel 66 is determined. The distance G is desirably set larger than the diameter F.

  As shown in FIG. 4, FIG. 28 and FIG. 29 of Patent Document 1 also have a drainage channel inner diameter F1 and a drainage channel diameter G1 smaller than the drainage channel inner diameter F1, and are smaller than the conduit cross-sectional area of the drainage channel inner diameter F1. There may be an area (diaphragm). If the throttle part is further present after the siphon phenomenon is induced in the drainage channel, the throttle part becomes a pressure loss, and there is a possibility that the drainage is accumulated and the discharge performance is lowered.

  On the other hand, since the minimum cross-sectional area of the drainage channel 66 is made larger than the cross-sectional area of the outlet end portion 14a of the drain trap pipe 14, the ease of flow is improved. In this embodiment, the distance D is set to 62 mm or more. It was confirmed that the residue and clogging of filth were improved under these conditions.

The drainage channel 66 is provided between the connection parts 62 and 66 and projects downward from the connection part 66. Such overhang, it is possible to ensure a long distance J ₁ shown in FIG. 8 (a) as described in Patent Document 1.

Drain passage 66, the center O eccentric to the wall surface W side than the center line M ₁ of the outlet end 14a of the drain trap pipe 14 has on the center line M ₂ a, spherical around the center O An overhang 67 is provided. If there is no eccentricity, the area P as shown in FIG. 5 becomes large, and it becomes difficult to direct the direction of the filth toward the drain outlet side, and the discharge performance is lowered. Due to the eccentricity, the direction of the filth can be directed toward the drain outlet, and the movement of the filth can be facilitated.

It is defined by the distance between the center line _{M 1} and _{M 2,} the eccentric amount E of the center of the projecting portion 67 is set to 1mm to 18 mm. By setting the amount of eccentricity E to 1 mm or more, the direction of the filth can be directed to the drain port side to facilitate the movement of the filth, but in order to effectively guide the filth to the drain port side, there is 10 mm or more. It is desirable. Moreover, sharp closest position angle leading to (end) 65a ₁ to the wall surface W of the lower end 65a of the outlet 65 of the connecting portion 64 from the deepest 67a of the drainage channel 66 by setting the amount of eccentricity E below 18mm Therefore, it is possible to prevent the filth from staying in the overhanging portion and to ensure the ease of flow.

  The distance B in the X direction from the outlet end portion 14a of the drain trap pipe 14 through the lower end 65a of the outlet 65 of the connecting portion 64 to the plane V parallel to the floor surface FL is set to 50 mm to 90 mm. The plane V is the same as the water surface of the drainage accumulated in the overhanging portion 67 of the drainage channel 66. By setting the distance B to 90 mm or less, siphon force is secured and clogging of filth is prevented. By setting the distance B to be equal to or greater than 50 mm, it is possible to prevent the drainage accumulated in the overhanging portion 67 of the drainage channel 66 from constantly contacting.

  As a result, the distance (B + H) in the Z direction (direction perpendicular to the end face 62a) from the end face 62a on the drain trap pipe 14 side of the connecting portion 62 to the plane V is 70 mm to 150 mm. Siphon power and ease of flow can be ensured under these numerical conditions.

Angle D between the straight line Q and the plane V connecting the deepest portion 67a positions the (end) 65a ₁ of the projecting portion 67 of the drainage passage 66 is set to 1 ° to 25 °. By setting the angle D to 1 ° or more, a space for the filth to rotate by 90 ° is secured, and the flowability is secured. By setting the angle D to 25 ° or less, the depth of the overhanging portion is increased and the filth is prevented from staying in the overhanging portion, and the ease of flow of the filth is ensured. In this way, the distance from the wall surface W to the deepest portion 67a is shortened as much as possible to ensure drainage performance.

The depth C of the deepest portion 67a is set to 30 mm or less, particularly 10 mm to 25 mm. The defined depth C over 10mm is to secure the distance J _1. The depth C of 30 mm or less is determined from the angle D and the distance A ′.

FIG. 6A is a cross-sectional view of the drain socket 60, and FIG. 6B is a perspective view of the drain socket 60. As shown in FIGS. 6A and 6B, the support portion 70 is placed on the floor surface FL and the rod member 72 that is fixed to the drain socket body 62 and supports the drain socket body 61 at one end. Pedestal 74. The height adjusting means 76 has a screw portion 73 formed on the outer surface from the center to the other end of the rod member 72 and a screw hole 75 formed as a through hole in the base 74 and engaged with the screw portion 73 of the rod member 72. . The height adjusting means 76 rotates the threaded portion 73 of the rod member 72 together with the drain socket body 61 so that the center line of the outlet 65 from the floor surface FL becomes the center line D ₂ of the inlet end D ₁ of the drain pipe D. as match, i.e., the inlet end portion D ₁ and the connecting portion 64 are adjusted nearly the height of the drainage socket body 61 at the same height. As described above, the height adjusting means 76 of the present embodiment can adjust the height of the drain socket body 61 in the range where the height J is 120 mm to 155 mm. The present invention is particularly effective with such a drain socket 60 having a variable height. However, the drain socket 60 may be dedicated to a height of 155 mm even if the height is not variable.

  Hereinafter, the operation of the toilet device 100 will be described with reference to FIGS. 7 (a) to 7 (h). Here, FIG. 7A to FIG. 7H are cross-sectional views for explaining the operation of the toilet device 100.

  First, the control unit 40 receives the operation of the toilet cleaning switch of the operation unit by the user, and performs the front rim cleaning by switching the switching valve 28 to the rim side. Specifically, tap water passes through the switching valve 28 and is discharged from the rim port 18 through the rim water supply path 18a. The water discharged from the rim port 18 descends while turning in the bowl portion 12 and cleans the inner wall surface of the bowl portion 12. The rim cleaning is performed through the rim water supply path 18a not through the pump 34. Washing of the rim 13 of the bowl portion 12 is sufficient even when the water pressure is weak, so that it is not necessary to pressurize and discharge the water in the tank 32 by the pump 34. For this reason, since the water in the tank 32 does not decrease, it is not necessary to supply water to the tank 32 after that, and it is possible to immediately shift to toilet cleaning and the subsequent supply of stored water.

  After the front rim cleaning, the control unit 40 switches the switching valve 28 to the tank side to start water supply to the tank 32 and controls the pump 34 to perform toilet flushing. Specifically, in the standby state of FIG. 7A, the water stored in the tank 32 flows into the pump 34 and is pressurized. The water pressurized by the pump 34 is discharged from the jet port 16 through the washing water conduit 33b. The washing water discharged from the jet port 16 flows into the drain trap pipe 14 and fills the drain trap pipe 14 to cause a siphon phenomenon. This state is shown in FIG. Thereby, the accumulated water and filth in the bowl portion 12 are sucked into the drain trap pipe 14 and discharged from the drain pipe D. Even if the drain socket 60 is downsized, the drain performance equivalent to the conventional one is maintained. Next, as shown in FIG. 7C, air is sucked from the entrance of the drain trap pipe 14 to trigger the end of the siphon phenomenon.

  In toilet cleaning, the pump 34 rotates at high speed so that a large volume of water is discharged from the jet port 16 at low speed. As a result, the siphon phenomenon can be quickly generated and the accumulated water and filth can be quickly discharged. Moreover, since the siphon phenomenon occurs quickly, the amount of wasted water is reduced. Further, since the jet flow continues as shown in FIG. 7D even after the siphon phenomenon is cut off, the amount of air sucked when the siphon is cut off is small and the sound is quiet. Subsequently, as shown in FIG. 7E, the floating system material is discharged, and as shown in FIG. 7F, the discharging operation ends with the gradual decrease of the jet flow. Thereafter, the control unit 40 stops the pump 34 and finishes toilet cleaning. However, the control part 40 maintains the water supply to a tank. The control unit 40 supplies water to the tank 32 together with the start of toilet cleaning, and can supply the stored water at an early stage.

  Next, the control unit 40 switches the switching valve 28 to the rim side and starts rear rim cleaning. As shown in FIG. 7 (g), the water seal is almost completed by the return of the jet flow. The transition of the accumulated water rises by the second water discharge from the rim water discharge port 18, and the standby state shown in FIG. Thereafter, the switching valve 28 is switched to the tank side again to supply water to the tank. The stored water supply may be performed through the path 34b using a pump.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to these embodiment, A various deformation | transformation and change are possible within the range of the summary. For example, the cleaning method of the present embodiment is a siphon jet type using a pump, but a low tank type siphon jet type or siphon blow type not using a pump may be used. As a method of starting the siphon action of the tank-fed toilet, if the throttle is configured on the ceramic part or the socket side of the trap part in the above embodiment, the washing water stays in that part and the upstream side fills up early and the siphon phenomenon Can be caused. The aperture portion is disclosed in Patent Document 2.
