Description

Water closet is washed in the closed convection current of ring entirely

Technical field

The utility model relates to a kind of water closet; Relate in particular to a kind of water cleaning closet inside that utilizes in the water tank; And utilizing external water source or tap water through a kind of water saving fixtures, promotion is washed water closet entirely from the closed convection current of ring of the water of the arrival bedpan bottom that water tank is discharged.

Background technology

Ring is all arranged above the bedpan of existing common water closet, and this ring is as the flowing water passage, and the water of discharging from water tank flows into that the flowing water aperture that spreads all over whole ring through its underpart flows into bedpan behind this ring, thereby reaches the purpose of cleaning bedpan below the ring; When cistern water-discharging, current can form certain impact to ring inside, but the current that flow out from the flowing water aperture of its underpart again are just relatively little much to the impact force of bedpan, and it is inner that the momentum of current has all acted on ring, do not act directly on the bedpan.

In order to solve above-mentioned this problem; Proposed in Chinese patent 97199869.8 and 200410075198.6 claims 1; Be provided with " interior sidewall surface of the closet upper limb of directly facing in edge and the aforementioned pelvic part (1) makes the main water of cleaning spread all over the big clean water water guide path (16) to full week of closet upper limb " and " full week or its part that makes aforementioned clean water water guide path (16) overhangs towards the interior side of pelvic part (1) " in the bedpan;

Claims, manual and accompanying drawing in conjunction with above-mentioned two parts of patents; Its described " water guide path (16) " are not a flowing water platform clearly; So Chinese patent 01810417.7 and 03819005.2 is afterwards just arranged; If but do not have flowing water platform clearly, needing from water tank, to discharge sizable current could " make the main water of cleaning spread all over the closet upper limb greatly to full week ", thereby can not reach the purpose of water saving;

" the full week of water guide path (16) " from it next; The claims, manual and the accompanying drawing that combine Chinese patent 97199869.8 and 200410075198.6 again; Explain that its described " water guide path (16) " are whole circles around the bedpan upper limb, and be not segmentation, like this under the situation of its 4th embodiment and the 5th embodiment; Two strands of current will bump and swell at the bedpan front end, also might splash outside the bedpan.

In Chinese patent 01810417.7 claim 1, proposed; Be provided with " annular recess that the rising wood of bedpan inwall and approximate horizontal ground extend " in the bedpan; And " pressure flush water feed mechanism and be configured in the bottom of annular recess and, the flushing water that makes ejection is along circle round substantially the 1st flushing water ejection mechanism in a week of bedpan internal face " along annular recess ejection pressure flush water;

Claims, manual and accompanying drawing in conjunction with said patent; So-called in said patent " annular recess " " water guide path (16) " in aforementioned two parts of patents all are " circling round substantially a week along the bedpan internal face ", and are not segmentation; Function is identical in fact; But effect is just different, adds and has disposed " pressure flush water feed mechanism ", and such cleaning performance will be fine; But need configuration special " pressure flush water feed mechanism ", cost of production will be higher like this.

In Chinese patent 03819005.2

claim

1,15, proposed, be provided with " holding the canopy portion between the knot face " in the bedpan, and " rinse water has been discharged in the canopy portion of above-mentioned urinal portion and forms the 1st water spray portion of eddy flow at flange part and dirt; Rinse water is discharged into the 2nd water spray portion in the canopy portion of above-mentioned urinal portion along the direction identical with the direction of rotation of above-mentioned eddy flow "; and " near above-mentioned the 1st water spray portion is configured in the urinal portion that fore-and-aft direction with above-mentioned urinal portion is center one side and changes to the position of deep camber from small curve, near above-mentioned the 2nd water spray portion is configured in the urinal portion of opposite side and changes to the position of small curve from deep camber ";

Claims, manual and accompanying drawing in conjunction with said patent; So-called in said patent " canopy portion " also resembles " water guide path (16) " in aforementioned two parts of patents; And " annular recess " of back in a patent is the same, all along bedpan internal face week substantially, and is not segmentation; Function is identical in fact, and just effect is different; Utilize tank water to clean equally, under the situation of identical water supply volume, obviously cleaning performance can be much better than " water guide path (16) " in aforementioned two parts of patents in " the canopy portion " of said patent, also i.e. water-saving more under same cleaning performance;

But make the eddy flow direction that forms from the water of " the 2nd water spray portion " ejection identical with the eddy flow direction that the water that sprays from " the 1st water spray portion " forms; And " near above-mentioned the 1st water spray portion is configured in the urinal portion that fore-and-aft direction with above-mentioned urinal portion is center one side and changes to the position of deep camber from small curve; near above-mentioned the 2nd water spray portion is configured in the urinal portion of opposite side and changes to the position of small curve from deep camber "; So just also need one section quite long water channel at bedpan rear portion to use as diversion; And can not only lean on one section drainage channel from the water tank outlet to the bedpan to achieve the goal; In fact this water channel is exactly the part of ring, and said patent seems have been cancelled ring and do not fully phase out in fact, has just cancelled a part of ring of bedpan leading portion; In addition, so also can increase the production difficulty of product.

In conjunction with claims, manual and the accompanying drawing of above-mentioned four parts of patents, no matter be described " water guide path (16) " or " annular recess " or " canopy portion ", their change width does not have clear and definite narration yet.

Existing common water closet generally all is only to lean on the water that from water tank, ejects that bedpan is washed; Though spray-hole is arranged at the bedpan bottom; But the water of spray-hole ejection from then on is also from water tank; Because the water tank height is limited, the water pressure of from water tank, coming out is very low, needs more relatively water just can rinse bedpan well; Also there is the part water closet fully directly to utilize press water such as tap water to wash, but hydraulic pressure is had relatively high expectations, need the above pressure of 300Kpa, otherwise also be difficult to rinse well, and have very big sound during flushing.

In order to solve above-mentioned this problem; My utility model application number be 201020537634.8,201110222824.X, 201110222811.2,201110222784.9,201110222760.3 several kinds utilize external water source such as tap water to the water saving fixtures of water closet bowl portion water spray; Water inlet, delivery port, injection boosting mouth are arranged in the said water saving fixtures; Said water inlet connects external water source such as tap water; Delivery port is water outlet in water tank, sprays the boosting mouth and connects the injection boosting hole to bowl portion.

But several kinds of water saving fixtures of said my utility model are applied to just improve water closet bath effect behind the water closet, do not solve the cleaning charge water problems of water closet bedpan inwall.

Supplementary notes:

The above-mentioned specific embodiment two has just deducted part-structure in fact with the specific embodiment three and the specific embodiment four on the basis of the specific embodiment one; Equally; On the basis of the specific embodiment five, also can deduct the specific embodiment six and the specific embodiment seven and the specific embodiment eight that part-structure draws the similar specific embodiment two and the specific embodiment three and the specific embodiment four, here repeated description no longer.

In above-mentioned several specific embodiment, " recessed " shape pilot bridge 8 is lower than the water intake end 10 of two flowing water platforms 9, also is lower than the lower end of water jet 7; Also can make " recessed " shape pilot bridge 8 roughly equal in fact, or make " recessed " shape pilot bridge 8 roughly equal, though cleaning performance can be not ideal like this with the lower end of water jet 7 with the water intake end 10 of two flowing water platforms 9; But can be too not poor yet; Always to produce easily, not shelter evil people and countenance evil practices hygiene than existing common water closet.

Drainage channel 5 also is communicated with " U " shape ring 14 on bedpan 4 tops; So just can make the production technology of the utility model the same as the production technology of the water closet of flowing water passage with the common ring that utilizes; Very simple; Because do not spread all over the flowing water aperture of whole ring on " U " shape ring 14, promptly " U " shape ring 14 is closed with respect to bedpan 4 internal upper parts, is not communicated with bedpan 4 internal upper parts again; The water that from water tank 2, emits like this; Two port ones 5 that can be simultaneously flow to " U " shape ring 14 are because the inner air of " U " shape ring 14 discharges nowhere, so current just can not get into " U " shape ring 14 inside; The potential energy of water can not consume " U " shape ring 14 internal pair production energy in the water tank, and the potential energy of water is converted into kinetic energy cleaning bedpan 4 inside through two water jets 7 of drainage channel 5 one ends; Though also can be in process of production two port ones, 5 sealings of " U " shape ring 14 reach make current not get into " U " thus shape ring 14 is inner does not produce the purposes that energy consumes; But because the particularity of Production of Ceramics; Will make production technology very complicated like this; Gypsum mold is hard to manage, and workman's troublesome poeration finally is directed at cost of production and rises;

" recessed " shape pilot bridge 8 is set in the utility model; Main purpose is in order to be that two leads described in 201110369717.X, 201110369746.6,201120451517.4, four patents such as 201120451470.1 clean the pelvic surface of sacrum below " recessed " shape pilot bridge 8 better than the application number of my utility model in early stage, makes the dirt that is cleaned mostly count dirts with other and be discharged from bedpan 4 synchronously; If do not establish " recessed " shape pilot bridge 8; Pelvic surface of sacrum below " recessed " shape pilot bridge 8 is difficult to be cleaned, and needs to beat cleaning aperture or additive method in addition and solves, and has so just increased the operation of producing and can influence attractive in appearance; Also can clean to two pelvics surface of sacrum below the lead though have few part current when the current of ejection finish nearly from water jet 7; But this moment, the blowdown process of water closet all finished, was cleaned the dirt that gets off and can not be discharged from bedpan 4, can only rest in the bedpan 4.
