{ the 5th invention }

But, in above-mentioned known Western water closet, no matter flange part is opening flange part or closo flange part, be arranged on make in the edge side water stream channel spue the situation of wash mill of slurry from left and right sides direction under, since slurry in edge side water stream channel or the place ahead of cup-shaped portion collide generation noise and lack silence during collision.In addition, such Western water closet because in the collision of cup-shaped portion the place ahead slurry, slurry disperses and splashes down to ground, has the anxiety on adhesional wetting ground.

At this point, if Western water closet adopts the words of closo flange part, for example be arranged in the edge side water stream channel from the spue wash mill of slurry of left and right sides direction, make slurry in cup-shaped portion, do rotation easily and can guarantee the discharging performance of dirt, utilization makes the jetting orifice that is arranged at A lower side wall portion present the result of inclination, relaxing the collision of slurry in cup-shaped portion the place ahead, can be in the silence of realizing to a certain degree, prevent slurry splashing earthward.Yet, in this case, the jetting orifice must be set correctly, form the complicated of flange part structure, increased manufacturing process, in other words, caused the increase of manufacturing cost.In addition, in this Western water closet, in the closo flange part, produce slurry and Air mixing during the washing beginning,, at this time be easy to generate noise, the problem that lacks silence is also arranged because mixing water is to penetrate from a plurality of jetting orifices.So so long as adopt the closo flange part,, also can leave over this increase manufacturing cost and reduce the problem of silence even only be arranged in the edge side water stream channel from the spue wash mill of slurry of a side direction.

The 5th invention is made in view of above-mentioned actual conditions in the past, and the 5th problem that its desire solves provides a kind of Western water closet of not worrying bedewing the discharging performance optimization of ground, cup-shaped portion washability and dirt and can realizing cheap for manufacturing costization when making silence good.

The Western water closet of the 5th invention, possesses cup-shaped portion, be formed at the cup-shaped portion upper limb and have the flange part of edge side water stream channel in inside, have the Western-style closestool body of the bent portion that connects the cup-shaped portion lower end, and the slurry that can spue is given the wash mill of edge side water stream channel; The slurry that spues from this wash mill washs usefulness through edge side water stream channel for cup-shaped portion, it is characterized by:

Above-mentioned flange part forms and makes edge side water stream channel expose the shape of above-mentioned cup-shaped portion, and above-mentioned wash mill is set as slurry is spued from a direction in edge side water stream channel.

In this Western water closet, be the slurry that spues from wash mill towards edge side water stream channel.Because slurry only spues from a direction, slurry constantly imports in the edge side water stream channel with a direction and flows to cup-shaped portion gradually,, discharges by bent portion along cup-shaped portion rotation (one-sided rotation) with equidirectional again.Therefore and since slurry in edge side water stream channel or the place ahead of cup-shaped portion do not collide, do not produce noise.In addition, in this Western water closet, because opening flange part is exposed to cup-shaped portion with edge side water stream channel, slurry and Air mixing in the time of can not producing the washing beginning, because slurry carries out jetting by the opening wideer than the jetting orifice of closo flange part, do not produce noise this moment again yet.Therefore, silence is good.

In addition, in above-mentioned Western water closet,, can not bedew ground because the collision that does not produce slurry in the place ahead of cup-shaped portion does not have dispersing of slurry.And, in this Western water closet,, can guarantee the cleansing power of cup-shaped portion by strengthening the flow of water of slurry.In addition, the direction in slurry one edge is discharged on one side in cup-shaped portion rotation (one-sided rotation), and the discharging performance of dirt is also very good.

In addition, in this Western water closet, because no jetting orifice, so the simplification of the structure of flange part, manufacturing process reduces, and in other words, can realize cheap for manufacturing costization.

The Western-style closestool body of the 5th invention preferably has the next door with edge side water stream channel and rear isolation.If such structure, owing to slurry is not imported rear side, so slurry is not wasted the water-saving result height.

In addition, the Western-style closestool body of the 5th invention border that is preferably in cup-shaped portion and flange part has the section portion of formation edge side water stream channel.If such structure, because section portion positively forms edge side water stream channel, the slurry that spues from wash mill is imported the downstream easily fully, reach fully clean in the cup-shaped portion in, can obtain better dirt discharging performance again.

The upstream side that this section portion is preferably in the slurry that spues from wash mill imports cup-shaped portion and downstream with slurry, only slurry is imported cup-shaped portion in downstream.If such structure because the slurry that spues from wash mill is not to flow directly to cup-shaped portion at the upstream side of edge side water stream channel, but flows to cup-shaped portion again up to importing downstream, therefore can carry out the washing in the cup-shaped portion fully.In addition, take this to make slurry easily in cup-shaped portion, to be rotated, can improve the dirt discharging performance.In addition, owing to only slurry is imported in the cup-shaped portion, slurry is rotated, do not remain in the edge side water stream channel etc. once again, therefore can not waste slurry, and obtain high water-saving result in downstream.

{ the 6th invention }

But, in above-mentioned Western water closet in the past shown in Figure 28,, form reflection via the slurry of jet 93 ejections by upper side wall 92a to various directions from wash mill according to position and the shape of the upper side wall 92a of bent portion 92.So, at slurry by upper side wall 92a to the outfall 92b of bent portion 92 and under the unreflected situation, slurry can be subjected to bigger impedance before arriving outfall 92b.In addition, collision between the slurry of upper side wall 92a reflection also can take place.Therefore, its drainage is low, also can constitute the reason that siphonage descends.Thereby, for the decline that compensates the siphonage that forms thus is the decline that dirt is discharged ability, must use a large amount of slurries.

The 6th invention is made in view of above-mentioned actual conditions in the past, and the 6th problem that its desire solves provides a kind of Western water closet that uses a small amount of slurry can fully discharge dirt.

The Western water closet of the 6th invention possesses cup-shaped portion, connects the bent portion of this cup-shaped portion lower end, and is located at this bent portion in order to the jet along this bent portion ejection slurry, it is characterized in that:

Forming at above-mentioned bent portion will be from the slurry of the above-mentioned jet ejection reflecting surface to the outfall reflection of bent portion.

In the Western water closet of the 6th invention, form at above-mentioned bent portion that penetrate will be from the slurry of the above-mentioned jet ejection reflecting surface to the outfall reflection of bent portion.Therefore, the slurry that is reflected can not take place with the wall than reflecting surface downstream to collide and discharge from outfall, and the collision between slurry can not take place yet.By this, improve drainage, strengthened siphonage.

Reflecting surface preferably will vertically be reflected from the slurry of jet ejection.Like this, the slurry that is reflected has more increased its velocity of discharge because of the effect of gravity.Therefore, can further improve drainage, strengthen siphonage, increase the discharge ability of dirt.

In addition, the angle that forms of the center position of the reflecting surface angle that preferably will constitute perpendicular to the imaginary line of this reflecting surface with by the injection direction of the slurry of jet ejection and imaginary line and outfall is made as equal angles.If so, owing to the center position that after the primary event of slurry via reflecting surface of jet ejection, is directed to outfall, siphonage can under the state of the flow of water that keeps slurry, arrive outfall, because of can take place its high drainage forcefully.On the other hand, if not like this, owing to take place to collide several times till arriving outfall from the slurry of jet ejection, the impedance of slurry increases, and the velocity of discharge reduces greatly, forms the decline of drainage, and the decline of siphonage.

Jet preferably is arranged to the lower side wall ejection slurry along bent portion.Residual dirt is deposited on the lower side wall of bent portion along with the process of time in the retaining.Therefore, if jet then can be discharged this deposit and make it can not residue in bent portion along the lower side wall ejection slurry of bent portion, can positively discharge dirt.

Be preferably in the storage part bottom of the bent portion of guaranteeing retaining, accumulate the portion of accumulating of slurry less when being formed on the spoil disposal casting forming as far as possible, and connect the lower side wall that this accumulates portion, the injection direction of the slurry that sprays with jet extends in parallel.Constitute the Western-style closestool body of the Western water closet of the 6th invention, since complex-shaped, generally form by the spoil disposal casting forming.Under situation about being shaped like this, the portion of accumulating of accumulating that can easily the discharge slurry be used is located at the bottom, storage part of the bent portion of guaranteeing retaining.If the above-mentioned portion of accumulating accumulates slurry in large quantities, accumulate the lower side wall of the continuous bent portion of portion with this, the injection direction that then forms the slurry that sprays with jet extends not parallelly.If so, then make the deposit that is deposited on bent portion lower side wall residue in bent portion easily.In contrast, if make the portion of accumulating accumulate slurry less as far as possible, the lower side wall of bent portion can be extension abreast with the injection direction of the slurry of jet ejection.If so, then be not easy to make the deposit that is deposited on bent portion lower side wall to residue in bent portion.

As wash mill, except that slurry casees such as lower water box in the past, also can adopt with the feed pipes such as water pipe of supplying with slurry by the outside directly be connected, device that the switching by valve can spue slurry.When adopting a kind of wash mill in back, the effect of the 6th invention is bigger.In other words,, compare with the situation that preceding a kind of wash mill is connected with jet if jet is connected with a kind of wash mill in back, can be easily from the stronger slurry of the jet ejection flow of water.

{ the 7th invention }

But, about above-mentioned Western water closet in the past shown in Figure 29, the miniaturization of Western-style closestool body 91 is not inquired into, and is done to maximize easily when as a whole.Therefore, in recent years dwelling house etc., can't obtain the space to save, can't guarantee than the lavatory of large space stricturization more and make.

The 7th invention is made in view of above-mentioned actual conditions in the past, and the 7th problem that its desire solves provides a kind of Western water closet of realizing miniaturization.

{ the 5th invention }

Below, specify the 5th working of an

invention form

1,2 with reference to accompanying drawing.

(example 1)

As shown in Figure 10 and Figure 11, the Western water closet of example 1 possesses the Western-style closestool body 5 of ceramic and is located at wash mill on this Western-style closestool body 5.Toilet seat and toilet cover have been omitted in the diagram.

Western-style closestool body 5 has the excremental cup-shaped portion 1 of admittance, is formed at the opening flange part 2 of the whole upper limb of cup-shaped portion 1, and the bent portion 3 that connects cup-shaped portion 1 lower end.

In addition, the rear mounting of Western-style closestool body 5 has the not shown slurry case as a wash mill part, this slurry case with can provide the water pipe of slurry to be connected by not shown pipe arrangement.Below the slurry case, have as a wash mill part with Western-style closestool body 5 relative and flexible pipes 8 that extend to the right.

Interface at cup-shaped portion 1 and opening flange part 2 forms prominent section portion 6 to the inside, forms edge side water stream channel 4 by this section portion 6 in opening flange part 2.Edge side water stream channel 4 is exposed to cup-shaped portion 1, by the inside wall portion of opening flange part 2 and the opening 4a of cup-shaped portion 1 formation, to cup-shaped portion 1 jet cleaning water.The front end of flexible pipe 8 is positioned at edge side water stream channel 4.

Shown in Figure 12～14, the interior inclined plane 6a that the top formation of section portion 6 is tilted to the inside, and the flare inclined-plane 6b that tilts laterally.As Figure 10 and shown in Figure 12, at the slurry upstream side that spues from flexible pipe 8, inclined plane 6a forms less area in making, and flare inclined-plane 6b forms bigger area.As Figure 10 and shown in Figure 13, flow to the way in downstream at the slurry that spues from flexible pipe 8, inclined plane 6a and flare inclined-plane 6b form area about equally in making.And as Figure 10 and shown in Figure 14, in the slurry downstream that spues from flexible pipe 8, interior inclined plane 6a forms bigger area, and flare inclined-plane 6b forms less area.Then, inclined plane 6a in downstream only forms.

In addition, as shown in Figure 10 and Figure 11, Western-style closestool body 5 has the circular-arc next door 7 that edge side water stream channel 4 and rear are isolated.

In the Western water closet of structure as mentioned above, to the wash switch application of force, slurry promptly spues towards edge side water stream channel 4 by flexible pipe 8 from the slurry case by the user.At this moment, because flexible pipe 8 only is equipped with in the right side facing to Western-style closestool body 5, so the slurry that spues is imported into edge side water stream channel 4 and flows to cup-shaped portion 1 gradually with dextrorotation, rotation is discharged from via bent portion 3 with dirt then in cup-shaped portion 1.

So, in this Western water closet because flexible pipe 8 only is located at one-sided position, slurry can be in edge side water stream channel 4 or the place ahead of cup-shaped portion 1 collide, thereby can not produce noise.In addition, in this Western water closet, because opening flange part 2 makes edge side water stream channel 4 be exposed to cup-shaped portion 1, when the washing beginning, can not produce slurry and Air mixing, because slurry is to carry out jetting by the opening 4a wideer than the jetting orifice of closo flange part, can not produce noise this moment yet.Therefore, its silence is quite good.

In addition, in this Western water closet,, do not have splashing of slurry, thereby can not bedew ground because slurry can not collide in the place ahead of cup-shaped portion 1.Therefore, can not give the user with discomfort.In addition, in this Western water closet,, can guarantee the washability of cup-shaped portion 1 by strengthening the flow of water of slurry.And, because rotating (one-sided rotation) limit with a direction limit, slurry imports cup-shaped portion 1, the discharging performance of its dirt is also quite good.
