Description

Toilet seat

Technical Field

The utility model relates to a squatting pan technical field especially relates to a can produce strong whirl in order to wash and produce the squatting pan of blowdown effect.

Background

The existing toilet bowl or toilet bowl generally has some problems, such as poor cleaning effect or poor dirt discharge efficiency, especially on the basis of having water-saving function. Therefore, under the requirement of water saving, less fixed water amount is required to achieve better cleaning effect and sewage discharge function, and the use of cleaning water to generate rotational flow has been widely used, for example, a plurality of water nozzles are arranged above the urinal to achieve the rotational flow effect, and the water nozzles are arranged in front of or behind the urinal to increase the sewage discharge function.

Chinese patent No. ZL03819005.2 discloses a "flush toilet" which is substantially the same as the prior art, and includes a skirt portion provided in a lower half portion, a toilet bowl portion formed in front of an upper half portion, and a water guide passage and a water discharge passage formed in upper and lower portions of a rear portion. More particularly, if the sink portion is centered in the front-rear direction, the first and second water outlets are respectively provided at both sides of the center, so that a fixed amount of the washing water from the tank flows through the water guide passage, and then the washing water is branched from the two flange connecting holes, which are separated from each other in the upper and lower directions, to the first and second water outlets, and then flows into the waste receiving surface of the sink portion along the ceiling portion adjacent to the flange in a sequential manner, thereby generating a rotational flow in a specific direction to wash the waste receiving surface, particularly the drying surface thereof. In addition, a part of the washing water entering from the lower flange coupling hole is branched to the press-in washing water jet port located under the water surface, and is used for pressing the sewage in the direction of the drainage passage and discharging the washing water.

As described above, the patent document mainly discloses three washing water flows, two of which can flow into the toilet bowl from different positions of the canopy portion while moving along the canopy portion to generate a swirling flow effect, thereby achieving an effect of washing the waste receiving surface, and the third washing water flow presses the waste from below the water surface of the toilet bowl to press the waste into the drain passage.

Admittedly, the above-mentioned patent does achieve certain desired results, but still suffers from certain drawbacks, such as, for example, a second stream of washing water issuing from a second water jet, the purpose is to make up for the shortage of the first stream of washing water flowing out from the first water jet, but the path of the second stream of washing water is approximately the same as the advancing track of the first stream of washing water along the shed part before flowing out from the first water jet, and the second stream of washing water flows towards the front of the urinal and flows towards the back of the urinal after turning a turn in front, so that the purpose can be easily understood, the second stream of cleaning water must pass through a longer diversion path, which, in addition to reducing the power of the water flow and thus reducing the cleaning effect on the dirt receiving surface, also greatly delays the point in time of the outflow from the second water jet, so that the swirling effect which can be produced by the mutual convergence of the first stream of cleaning water and the second stream of cleaning water is greatly reduced. Ideally, the time of the first stream of washing water flowing out from the first water jet and the time of the second stream of washing water flowing out from the second water jet should be synchronous or at least very close to each other, so that the two streams in the same rotating direction can mutually push each other to generate a multiplication effect after being converged, and the strongest swirling effect can be achieved. However, obviously, when the first stream of washing water flows out from the first water jet and starts flowing into the toilet bowl along the shed portion to perform the washing function, the second stream of washing water is still limited to flow in the water passage of the second stream of washing water, and flows out from the second water jet when the first stream of washing water almost runs out of the whole path along the shed portion, and the flowing time of the two streams is far away, so that the better swirling effect cannot be achieved.

In addition, when the third washing water branched from the lower flange connection hole flows from the bottom opening along the water passage to the press-in washing water spray nozzle under the water surface of the toilet bowl, the flow path of the third washing water is short and flows from top to bottom at a slight inclination, so that although a good pressing effect can be generated to the dirt under the water surface and a siphon action can be generated even early, the flow time of the third washing water is too long from the time point of starting the siphon action, which may cause the siphon action to be generated, but the subsequent water supply action force is insufficient and not continuous, thereby affecting the siphon effect and being not beneficial to the discharge of the dirt. Ideally, after the siphon action of the third washing water is initiated, the first and second washing waters should be converged to each other to generate a rotational flow, and then the water is supplied in a concentrated manner within a minimum time, so that the siphon action is maintained at an optimum state, thereby achieving the best dirt discharge capacity and effect.

The following describes the specific implementation of the present invention in more detail with reference to specific embodiments:

as shown in fig. 1 to 3, the present invention provides a preferred embodiment of a toilet, wherein the toilet 1 mainly comprises:

the urinal part 10 has a bowl-shaped dirt receiving surface 11, an inner edge part 12 with an upper inner peripheral surface slightly protruding inward, and a canopy part 13 formed between the dirt receiving surface 11 and the inner edge part 12. The toilet bowl 10 of the present embodiment is formed in front of the upper part of the toilet 1, and a skirt 100 is formed in front of the lower part of the toilet 1.

A drain pipe 20 having an inlet 21 formed at one end thereof, the inlet 21 being connected to a lower portion of the stool part 10 for discharging contaminants. The sewage drain pipe 20 of the present embodiment is formed at the rear of the lower portion of the toilet bowl 1.

The inlet channel 30 has an inlet port 31 formed at one end thereof to allow washing water to flow therein, and a diverging region 32 formed at the other end of the inlet channel 30. The water inlet channel 31 of the present embodiment is formed at the rear of the upper portion of the toilet 1, and the water tank 300 is connected to the upper portion of the water inlet 31 for storing a certain amount of cleaning water, and the cleaning water can be controlled to flow into the water inlet channel 30 from the water inlet 31 connected to the lower portion.

The first water outlet channel 40, one end of which is connected to the diverging region 32 of the water inlet channel 30, can guide the cleaning water to the first water outlet 41 at the other end and then flow to the shed 13 of the urinal portion 10 to form a first water flow.

The second water outlet channel 50 has one end connected to the diverging region 32 of the water inlet channel 30, and can guide the cleaning water to the second water outlet 51 at the other end and then flow to the shed 13 of the urinal portion 10 to form a second water flow.

The injection pipe 60 has one end connected to the diverging region 32 of the inlet channel 30, and guides the cleaning water to the injection hole 61 at the other end to flow to the water surface at the bottom of the urinal portion 10 to form a third water flow. The spraying hole 61 of this embodiment is located in front of the urinal portion 10 and is aligned with the inlet 21 of the sewage drain pipe 20.

Wherein, the front and the back of the pool part 10 are taken as a central axis X, the first water outlet channel 40 and the second water outlet channel 50 are respectively positioned at two sides of the central axis X, the first water outlet 41 is positioned at the middle section between the junction position P1 of the toilet bowl 10 changing from a small curvature radius to a large curvature radius and the rear position P2 of the toilet bowl 10, and the second water outlet 51 is positioned at the middle section between the junction position P3 of the toilet bowl 10 changing from a large curvature radius to a small curvature radius and the rear position P2 of the toilet bowl 10; the second water outlet channel 50 has a turning portion 52 for guiding and turning the water flow, so that the second water flow flows from the second water outlet 51 to the shed portion 13 along the water flow direction of the shed portion 13, and the first water flow flows from the first water outlet 41 to the shed portion 13 along the water flow direction of the shed portion 13, so that the second water flow is consistent with the first water flow direction along the shed portion 13, thereby generating a swirling action.

In the embodiment, the arc distance from the first water outlet 41 to the position P1 along the canopy 13 is S1, the arc distance from the position P2 to the first water outlet 41 along the canopy 13 is S2, and S1/S2 is between 0.4 and 0.6.

In the present embodiment, as shown in fig. 3, the arc distance from the second water outlet 51 to the position P2 along the canopy 13 is S3, the arc distance from the position P3 to the second water outlet 51 along the canopy 13 is S4, and S3/S4 is between 0.2 and 0.4. As can be seen from the above, the distance between the second water outlet 51 and the position P2 appears to be shorter than the distance between the first water outlet 41 and the position P2, but since the middle of the first water outlet 40 is designed with a turning part 52, the water path length of the second water outlet 50 is actually slightly shorter than or equal to the water path length of the first water outlet 40, so that the design can ensure that the first water flow flowing out from the first water outlet 41 and the second water flow flowing out from the second water outlet 51 can keep the difference between the water outlet time of the two within 1.5 seconds.

In the present embodiment, as shown in fig. 5, the sectional area of the first water outlet 41 is larger than the sectional area of the second water outlet 51. For example, the first water outlet 41 may be configured as a circular hole having a diameter

22mm, and the second water outlet 51 can be provided with a long runway-shaped hole with a length L of 28mm and a width W of 10mm, so that the water cross-sectional area a1 of the first water outlet 41 is ensured to be larger than the water cross-sectional area a2 of the second water outlet 51, that is, the water quantity flowing out from the first water outlet 41 is larger than the water quantity flowing out from the second water outlet 51 under normal conditions.

It should be particularly emphasized that the shape of the first water outlet 41 is preferably a circular hole, but may also be a racetrack-shaped hole or a rectangular hole; the shape of the second water outlet 51 is preferably a long racetrack hole, but may be a circular hole, a rectangular hole, or the like.

In the present embodiment, in a state where the water supply amount of the water inlet passage 30 is 4.8 liters (L), the water division ratio of the first and second water outlets 41 and 51 to the injection hole 61 is about 0.6: 0.4: 3.8. that is, when the water tank 300 stores a fixed amount of washing water of 4.8L, the amount of water flowing out of the first water outlet 41 is about 0.6L, the amount of water flowing out of the second water outlet 51 is about 0.4L, and the amount of water flowing out of the injection hole 61 is about 3.8L. By the above-mentioned design of the water outlet amount, the largest amount of water can be ensured to flow out from the injection hole 61, so as to ensure that the filling of the pushed dirt and the dirt inlet amount is increased, thereby promoting the generation of sufficient siphon action to smoothly discharge the dirt from the sewage pipe 20, while the second largest amount of water flows into the urinal portion 10 from the first water outlet 41 along the longer shelf portion 13, thereby performing the cleaning action on the most dirt receiving surface 11, and the smallest amount of water flows into the urinal portion 10 from the second water outlet 51 along the shorter shelf portion 13, thereby performing the cleaning action on the remaining small dirt receiving surface 11.

In the present embodiment, as shown in FIG. 6, the bottom wall surface of the shelf part 13 is inclined from the inside toward the center of the toilet bowl part 10 by an amount t of 0 to 2.5 mm. Due to the low-slope design, the second water flow flowing out from the first water outlet 41 and the second water outlet 51 can be ensured, and the second water flow can flow along the shed portion 13 and can be uniformly dispersed downward to be discharged into the toilet bowl portion 10 for cleaning.

In the present embodiment, as shown in fig. 6 and 7, the width W1 of the canopy 13 gradually narrows from the position of the first water outlet 41 to the position near the position P1 along the water flow direction, has the same width from the position near the position P1 to the position near the position P3 along the water flow direction, gradually narrows from the position near the position P3 along the water flow direction to the position of the second water outlet 51, and gradually narrows from the position of the second water outlet 51 along the water flow direction to the position of the first water outlet 41; the width W1 of the canopy 13 at the position of the first water outlet 41 is substantially equal to the width W1 of the canopy 13 at the position of the second water outlet 51. As is apparent from the above design, the narrowing is provided to facilitate the water flow to be evenly dispersed downward and discharged into the urinal 10 for cleaning.

In the present embodiment, the width of the water channel 30 is gradually narrowed from the position of the water inlet 31 to the diversion area 32 along the water flow direction as shown in fig. 8 and 9. For example, the cross-sectional shape of inlet channel 30 is generally bowl-male, with width W2 being 102mm and height H1 being 44mm near the location of inlet 31 (section line A-A), and width W3 being 96mm and height H2 being 47mm near the location of diverter region 32 (section line B-B).

In the present embodiment, as shown in fig. 10, the width of the first water outlet channel 40 is gradually narrowed along the water flow direction; the width of the second water outlet channel is gradually narrowed along the water flow direction. For example, the first water outlet channel 40 has a generally rectangular cross-sectional shape with a width W4 near the inlet (section line C-C) of 25mm and a height H3 of 40mm, and a width W5 near the first water outlet 41 (section line D-D) of 17mm and a height H3 of 40 mm. As shown in FIG. 11, the cross-sectional shape of the second water outlet channel 50 is also substantially rectangular, with a width W6 near the inlet (section line E-E) of 22mm and a height H4 of 40mm, and a width W7 near the second water outlet 51 (section line F-F) of 15mm and a height H4 of 40 mm.

It is obvious from the above design that the narrowing of the water channels inside the water inlet channel 30, the first water outlet channel 40 and the second water outlet channel 50 is designed to increase the water speed, so that the water streams flowing out from the first water outlet and the second water outlet can generate stronger impact force on the dirt receiving surface 11 when being dispersed and discharged inside the urinal 10 along the ceiling portion, thereby improving the cleaning effect. Similarly, the inner width of the injection pipeline can also adopt a gradually narrowing design.

In the present embodiment, as shown in fig. 1 and fig. 12 to 14, a part of the side wall of the first and second

water outlet passages

40 and 50 and the side wall of the neighboring housing 13 are formed by a partition plate assembly c adhered between the bottom wall a of the first and second

water outlet passages

40 and 50 and the top wall of the seat b. The partition plate assembly c comprises a first partition plate c1 and a second partition plate c 2; the first partition plate c1 is in the shape of a long arc and is used for forming a part of side wall walls of the first water outlet channel 40 and the second water outlet channel 50, and the first water outlet 41; the second partition C2 is L-shaped, U-shaped or C-shaped, and is used to form a part of the side wall of the second water outlet channel 50 near the second water outlet 51, and forms a part of the second water outlet 51 together with the first partition C1. The design of the partition board can produce good flow guiding effect, and the independent partition board is beneficial to accurate and simple forming, and is integrally formed on the toilet bowl 1 through simple adhesion and fixation after forming.

As is clear from the above description, the toilet 1 of the present invention has the following features and can achieve the effects:

first, the toilet 1 utilizes the first water outlet channel 40 and the second water outlet channel 50 to respectively divert water from the diversion area 32 of the water inlet channel 30 in different directions, which has the advantages that: the turning part 52 is only needed to be arranged in the second water outlet channel 50 to guide and turn the water flow, so that the flow direction of the second water flow after flowing out from the second water outlet 51 and entering the shed part 13 is consistent with the first water flow, compared with the known structure, the water flow path length of the second water outlet channel 50 can be greatly shortened, and the first water flow and the second water flow almost synchronously flow out. The advantage of the synchronous outflow is that the first and second flows can move forward along the shed 13 and simultaneously uniformly disperse and flow into the urinal 10, so that they converge to form a strong rotational flow, thereby avoiding the situation that the rotational flow effect is reduced by the two flows in tandem, and therefore, the cleaning effect of the waste receiving surface 11 can be greatly improved.

Secondly, since the strong swirling flows can be formed by converging each other earlier, the strong swirling flows can interact with the third water flow flowing out from the injection holes 61 more quickly to generate a strong siphon action, and the sewage is discharged into the sewage discharge pipeline 20 from the inlet 21 strongly as air, so that a good sewage discharge effect can be achieved.

Thirdly, the toilet 1 can enhance the impact force of the water flow and the smoothness of the flow or the relief by increasing the flow speed with other fine structural designs, such as the narrowing design of the water inlet channel 30, the first water outlet channel 40, the second water outlet channel 50, and the width variation design of each position of the canopy 13, to achieve the above purpose, and further enhance the overall cleaning effect.

Fourthly, the toilet 1 utilizes the shape and width of the first outlet 40, the second outlet 50 and the injection pipe 60 to match the water flow cross-sectional area design of the first outlet 41, the second outlet 51 and the injection hole 61, so as to optimally distribute the quantitative cleaning water entering the inlet 30, and the first, the second and the third water flows can achieve the respective optimal cleaning or pollution discharge effects with relatively less water amount, without mutual involvement or involvement, thereby limiting the cleaning or pollution discharge effect of a certain area or position.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
