技术领域Technical field
本公开涉及马桶技术领域，特别涉及一种具有双冲洗水路的马桶冲水结构。The present disclosure relates to the field of toilet technology, and in particular to a toilet flushing structure having a double flushing waterway.
背景技术Background technique
相关技术的马桶冲水结构大致分为两种。在一种马桶冲水结构中，马桶本体内设有单一水路，水在边缘通道的入口端处才分流成两股，一股进入边缘通道，对便池内壁面进行洗刷，另一股向下进入喷射通道，对便池底部的喷射口进行喷射。在另一种马桶冲水结构中，马桶本体内设有双水路，一路水路接通边缘通道，一路水路接通喷射通道。马桶本体内的两路水路相互独立地进行供水冲洗。The toilet flushing structure of the related art is roughly classified into two types. In a toilet flushing structure, a single water passage is provided in the toilet body, and water is split into two strands at the inlet end of the edge passage, one enters the edge passage, scrubs the inner wall surface of the toilet bowl, and the other enters downward. The injection passage sprays the injection port at the bottom of the bowl. In another type of toilet flushing structure, a double waterway is provided in the toilet body, and one waterway connects to the edge passage, and one waterway connects the injection passage. The two waterways in the toilet body are independently supplied with water for washing.
不论是单一水路还是双水路，基于马桶本体结构以及水流流动原理，在每个工作循环之前，冲洗水路内均会充满空气。这些空气在整个冲水过程中起到很大的阻碍作用，降低了水的势能，特别是存在喷射通道内的这些空气较不容易排出。对于双水路而言，喷射通道内的空气在冲洗过程中一般是一部分逆着水流方向从马桶本体的水路进水口排出，另一部分在水流的带动下顺着水流方向从便池底部的喷射口排出。由于空气排出速度较慢，导致喷射虹吸形成较慢，从而增加了冲洗用水量。Whether it is a single waterway or a double waterway, based on the toilet body structure and the principle of water flow, the flushing waterway is filled with air before each working cycle. These airs greatly hinder the entire flushing process, reducing the potential energy of the water, especially if the air present in the jet channel is less likely to be discharged. For the double waterway, the air in the injection channel is generally discharged from the water inlet of the toilet body in the direction of the water flow during the flushing process, and the other part is discharged from the injection port at the bottom of the toilet bowl in the direction of the water flow by the water flow. . Due to the slower air discharge rate, the jet siphon formation is slower, which increases the flushing water consumption.

参考图1-图4，在一些实施例中，本公开具有双冲洗水路的马桶冲水结构包括：马桶本体10、水箱20和冲水阀30。水箱20设于马桶本体10的后部，冲水阀30设于水箱20内。Referring to FIGS. 1-4, in some embodiments, a toilet flushing structure having a dual flush waterway of the present disclosure includes a toilet body 10, a water tank 20, and a flush valve 30. The water tank 20 is provided at the rear of the toilet body 10, and the flush valve 30 is provided in the water tank 20.
该马桶冲水结构还包括：边缘通道11、喷射通道12和排污通道13。边缘通道11设于马桶本体10的便池上部，用于对便池内壁面14的洗刷过程进行供水。喷射通道12用于对便池底部喷射口15的喷射过程进行供水。排污通道13与便池底部连通。The toilet flushing structure further includes an edge passage 11, an injection passage 12, and a sewage passage 13. The edge channel 11 is provided in the upper portion of the bowl of the toilet body 10 for supplying water to the washing process of the inner wall surface 14 of the bowl. The injection passage 12 is for supplying water to the injection process of the bowl bottom injection port 15. The drain passage 13 communicates with the bottom of the bowl.
马桶本体10内设有与水箱20接通的水道，该水道中设置有隔层40。隔层40将马桶本体10内的水道分隔成上层水道16和下层水道17。上层水道16与边缘通道11的入口端111接通，下层水道17与喷射通道12的入口端121接通。隔层40的前端设有连通边缘通道11的入口端111和喷射通道12的入口端121的连通口18。A water passage connected to the water tank 20 is provided in the toilet body 10, and a partition 40 is disposed in the water passage. The compartment 40 divides the water channel in the toilet body 10 into an upper water channel 16 and a lower water channel 17. The upper water channel 16 is connected to the inlet end 111 of the edge channel 11, and the lower water channel 17 is connected to the inlet end 121 of the injection channel 12. The front end of the partition 40 is provided with a communication port 18 that communicates the inlet end 111 of the edge passage 11 and the inlet end 121 of the injection passage 12.
在一些实施例中，冲水阀30具有两个出水口。该两个出水口分别是设置在冲水阀30底部侧壁的侧出水口31和设置在冲水阀底端的底出水口32。侧出水口31与上层水道的入口端161接通，底出水口32与下层水道的入口端171接通。这样，冲洗水从冲水阀30开始分流成两路，然后分别经上层水道16和下层水道17相互独立地流至边缘通道11和喷射通道12，使得两股水流互不干涉，从而减小水的势能损失。In some embodiments, the flush valve 30 has two water outlets. The two water outlets are a side water outlet 31 provided at the bottom side wall of the flush valve 30 and a bottom water outlet 32 provided at the bottom end of the flush valve. The side water outlet 31 is connected to the inlet end 161 of the upper water channel, and the bottom water outlet 32 is connected to the inlet end 171 of the lower water channel. Thus, the flushing water is branched into two paths from the flush valve 30, and then flows to the edge passage 11 and the injection passage 12 independently of each other through the upper water channel 16 and the lower water channel 17, respectively, so that the two water flows do not interfere with each other, thereby reducing water. The loss of potential energy.
在一些实施例中，冲水阀30密封地固设在水箱20内的安装孔21上。马桶本体10内的水道通过该安装孔21与水箱20接通。隔层40的后部对应安装孔21的位置设有下安装孔41。冲水阀30的底部穿设于安装孔21和下安装孔41，并与安装孔21和下安装孔41的尺寸相适配。侧出水口31位于安装孔21和下安装孔41之间的冲水阀 30底部侧壁上，底出水口32位于下安装孔41的下方。In some embodiments, the flush valve 30 is sealingly secured to the mounting aperture 21 in the water tank 20. The water passage in the toilet body 10 is connected to the water tank 20 through the mounting hole 21. The lower portion of the partition 40 is provided with a lower mounting hole 41 at a position corresponding to the mounting hole 21. The bottom of the flush valve 30 is bored in the mounting hole 21 and the lower mounting hole 41, and is adapted to the size of the mounting hole 21 and the lower mounting hole 41. The side water outlet 31 is located on the bottom side wall of the flush valve 30 between the mounting hole 21 and the lower mounting hole 41, and the bottom water outlet 32 is located below the lower mounting hole 41.
在一些实施例中，隔层40包括由后往前渐向下倾斜的倾斜段42。这里的前向可参考图2，即为从水箱到便池的方向。倾斜段42的最低点421的位置低于边缘通道的入口端111的位置。冲洗时，在倾斜段42的作用下，下层水道17的冲洗水被倾斜段42强行下压以尽量使得水流贴着喷射通道12的底壁流进，从而迫使喷射通道12内的空气在水的挤压下更快、更多地从连通口18向上排至边缘通道11中，加快了喷射通道12的虹吸形成。并且，由于倾斜段42的最低点421的位置低于边缘通道的入口端111位置，因此，喷射通道12内被困的空气能够向上经过连通口18，顺利地从边缘通道的入口端111进入边缘通道11，并最终沿边缘通道11的出水孔处排出。这样，喷射通道12中的空气能够快速有效地排出，从而减少了空气对水流势能的影响，有利于喷射虹吸的提早形成，并减小冲洗用水量。In some embodiments, the barrier layer 40 includes a sloped section 42 that slopes downwardly from the back to the front. The forward direction here can be referred to FIG. 2, which is the direction from the water tank to the toilet bowl. The position of the lowest point 421 of the inclined section 42 is lower than the position of the inlet end 111 of the edge channel. During rinsing, under the action of the inclined section 42, the flushing water of the lower water channel 17 is forcibly pressed by the inclined section 42 to flow the water as far as possible against the bottom wall of the injection passage 12, thereby forcing the air in the injection passage 12 to be in the water. The squeezing is performed faster and more upwardly from the communication port 18 into the edge passage 11, accelerating the siphon formation of the injection passage 12. Also, since the position of the lowest point 421 of the inclined section 42 is lower than the position of the inlet end 111 of the edge passage, the trapped air in the injection passage 12 can pass upward through the communication port 18, smoothly entering the edge from the inlet end 111 of the edge passage. The passage 11 is finally discharged along the water outlet of the edge passage 11. In this way, the air in the injection passage 12 can be quickly and efficiently discharged, thereby reducing the influence of the air on the potential energy of the water, facilitating the early formation of the jet siphon, and reducing the amount of flushing water.
在一些实施例中，隔层40还包括由倾斜段42的最低点421向上延伸的上升段422。上升段422与马桶本体10壁面之间形成连通口18。上升段422由下往上逐渐往前倾斜，以使得连通口18由下往上的横截面积渐变小，这种上升段422的设置和连通口18所形成的锥度更有利于喷射通道12内被困空气的排出。容易理解的，在其他一些可选的实施例中，也可以是直接在隔层40的前端开设一上下贯通的孔(未图示)，该孔形成所述连通口18。In some embodiments, the barrier layer 40 further includes a rising section 422 that extends upward from the lowest point 421 of the angled section 42. A communication port 18 is formed between the rising section 422 and the wall surface of the toilet body 10. The rising section 422 is gradually inclined forward from the bottom to the top, so that the cross-sectional area of the communication port 18 from the bottom to the top is gradually reduced, and the setting of the rising section 422 and the taper formed by the communication port 18 are more favorable for the injection passage 12. The escape of trapped air. It is easy to understand that in some other alternative embodiments, a vertically penetrating hole (not shown) may be formed directly at the front end of the spacer 40, and the hole forms the communication port 18.
在冲洗时，冲水阀30打开。一部分水从冲水阀30的侧出水口31流出，另一部分水从冲水阀30的底出水口32流出。侧出水口31流出的水沿着上层水道16流至边缘通道11中以对便池内壁面进行洗刷，底出水口32流出的水沿着下层水道17流至喷射通道12中以便从便池底部的喷射口15进行喷射，从而使得排污管13形成虹吸。在这个过程中，底出水口32流出的水受到隔层40的倾斜段42的引流作用，被压迫而流向喷射通道12的底部，且尽量贴着喷射通道12的底壁流动，从而迫使喷射通道12内的空气在水的挤压下更快、更多地从连通口18向上排至边缘通道11中，进而进一步加快喷射通道12的虹吸形成。此外，通过设置侧出水口31和底出水口32的大小比例可控制流入上层水道16和下层水道17的水量。At the time of flushing, the flush valve 30 is opened. A part of the water flows out from the side water outlet 31 of the flush valve 30, and the other part of the water flows out from the bottom water outlet 32 of the flush valve 30. The water flowing out of the side water outlet 31 flows along the upper water channel 16 to the edge channel 11 to wash the inner wall surface of the bowl, and the water flowing out of the bottom water outlet 32 flows along the lower water channel 17 to the injection channel 12 so as to be from the bottom of the bowl. The injection port 15 performs injection so that the drain pipe 13 forms a siphon. During this process, the water flowing out of the bottom outlet 32 is drained by the inclined section 42 of the partition 40, pressed to flow to the bottom of the injection passage 12, and flows as close as possible to the bottom wall of the injection passage 12, thereby forcing the injection passage. The air in the 12 is discharged faster and more from the communication port 18 into the edge passage 11 under the squeeze of water, thereby further accelerating the siphon formation of the injection passage 12. Further, the amount of water flowing into the upper water channel 16 and the lower water channel 17 can be controlled by setting the size ratio of the side water outlet 31 and the bottom water outlet 32.
在本公开的一些实施例中，在马桶本体10内的水道中设置隔层40，并通过隔层40将马桶本体内的水道分隔形成上层水道16和下层水道17。隔层40的前端设有连通边缘通道11和喷射通道12的入口端的连通口18，通过该连通口18可使得喷射通道12中的空气在冲水过程中向上经由连通口18排至边缘通道11，并从边缘通道11 排到外界，从而能够尽快地排出喷射通道12内的空气，使得喷射通道12尽快形成虹吸现象，进而提高冲洗性能，节约冲洗用水。In some embodiments of the present disclosure, a barrier 40 is provided in the water channel within the toilet body 10, and the waterways within the toilet body are separated by the barrier 40 to form the upper water channel 16 and the lower water channel 17. The front end of the partition 40 is provided with a communication port 18 that communicates the edge passage 11 and the inlet end of the injection passage 12, through which the air in the injection passage 12 can be discharged upward through the communication port 18 to the edge passage 11 during flushing. And discharging from the edge passage 11 to the outside, so that the air in the injection passage 12 can be discharged as soon as possible, so that the injection passage 12 forms a siphon phenomenon as soon as possible, thereby improving the flushing performance and saving the flushing water.
