Description

Technical Field

[0001] This utility model relates to an integrated anti-siphon protection device for the water circuit of a bidet. Background Technology

[0002] A water-pressure-controlled, extendable or retractable spray bar is installed in the hinge of the toilet seat. After defecation or urination, turning on the water supply valve causes the spray bar to extend against the spring force, and the nozzle at the front of the spray bar sprays water onto the private parts of the body to wash away feces or urine adhering to the skin. To address the possibility of the spray bar becoming contaminated or water flowing back into the drinking water network, a one-way valve or vacuum breaker needs to be installed on the water line upstream of the spray bar. However, when the drinking water network is shut off, a strong negative pressure suction force is generated in the network, and sewage or waste may still siphon back into the drinking water network through the spray bar, jeopardizing the hygiene and safety of the public drinking water network.

[0003] To address this, an early German invention patent, DE2534662(A1), disclosed a bidet device for a shower unit equipped with a single spray bar. This device utilizes a jet relay coupler connected to the upstream water path of the spray bar. This coupler consists of a spray connector connected to the drinking water pipe near the upstream control valve and a receiving connector 5 connected to the downstream receiving connector for the high-pressure water jet. Because the spray connector 4 and the receiving connector 5 are separated by a free space, if the drinking water supply is interrupted and negative pressure is generated, the water in the spray bar will absolutely not be able to siphon back to the spray connector 4 and then flow back into the drinking water network. However, in German patent DE2534662(A1), the spray connector 4 and the receiving connector 5 lack a protective cover to prevent water splashes and mist. Therefore, water droplets or mist generated by the high-speed water jet from the spray connector 4 to the receiving connector 5, if accumulated and adhered to the receiving end face of the spray connector 4, will affect the water pressure collected by the receiving connector 5, thus affecting the spray pressure of the spray bar.

[0004] Furthermore, the German utility model patent DE202006013209(U1) discloses a sitz bath with a partial spray device for the toilet seat. It still uses a single spray bar, with the upper part 18 of the backflow interruptor 3's outer shell acting as a support. The spray connector 13 and the receiving connector 14 are installed facing each other on the two side walls of the upper part 18 of the outer shell and separated by the free space inside the upper part 18 of the outer shell. Although it covers the water mist and splashes, it does not affect the function. However, the large volume of the upper part 18 will affect the low-profile appearance space design of the rear shell of the single-cooling cover. In addition, the spray connector 13 and the receiving connector 14 are installed separately on the upper part 18 of the outer shell as a module, which is not conducive to the miniaturization design of the jet relay coupler. Moreover, for sitz bath toilet seats that require dual spray bars for buttock washing or hot and cold water, multiple jet relay couplers need to be installed separately. Utility Model Content

[0005] This invention provides an integrated anti-siphon protection device for the water circuit of a bidet, which can effectively solve the above-mentioned problems.

[0006] This utility model is implemented as follows: An integrated anti-siphon protection device for the water circuit of a bidet includes: The container includes a bottom shell and a cover that interlock with each other; At least one jet coupler is installed in a container. The jet coupler has an inlet connector on the upstream side, an outlet connector on the downstream side, and a hollow section between the inlet connector and the outlet connector. The inlet connector has a pressure-gathering tube coaxially connected to the inlet connector. A jet hole is provided at the front end of the pressure-gathering tube. The outlet connector has a pressure-relief tube coaxially connected to the outlet connector. A receiving hole coaxially opposite to the jet hole is provided at the rear end of the pressure-relief tube. After the supplied water is pressurized by the pressure-gathering tube on the upstream side, a smooth water column is ejected from the jet hole. The smooth water column passes through the hollow section and enters the receiving hole on the downstream side. After being depressurized by the pressure-relief tube, it flows out from the outlet connector.

[0007] As a further improvement, a baffle is provided in the hollowed-out part in the direction of the smooth water jet ejection. A through hole is provided in the baffle, which is coaxial with the spray hole and the receiving hole. The smooth water jet is ejected into the receiving hole through the through hole.

[0008] As a further improvement, at least one first semicircular portion is provided on the rear side wall of the bottom shell, and a first semicircular portion is provided on the rear side wall of the cover to conformally engage with the first semicircular portion on the bottom shell. The water inlet connector is placed inside the first semicircular portion on the bottom shell. When the cover rotates to engage with the bottom shell, the first semicircular portion on the cover engages with the first semicircular portion on the bottom shell to fix the water inlet connector.

[0009] As a further improvement, at least one second semicircular portion is provided on the front side wall of the bottom shell, which is opposite to the first semicircular portion on the bottom shell. A second semicircular portion is provided on the front side wall of the cover, which conforms to the second semicircular portion on the bottom shell. The water outlet connector is placed inside the second semicircular portion on the bottom shell. When the cover is rotated to fasten the bottom shell, the second semicircular portion on the cover and the second semicircular portion on the bottom shell are fastened to fix the water outlet connector, thereby fixing the jet coupler inside the container.

[0010] As a further improvement, the bottom shell and the cover are connected by several flexible straps.

[0011] As a further improvement, a spring piece is provided in the middle of the outer wall of the end of the shell cover away from the soft band, and a slot is provided in the spring piece.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Reference Figures 1-3 , Figure 5 As shown, an integrated anti-siphon protection device for the water circuit of a bidet includes a collection box 20. The collection box 20 includes a bottom shell 21 and a cover 22 that are interlocked with each other, and also includes at least one jet coupler 10 that is fastened inside the collection box 20. In this embodiment, there are two jet couplers 10. Each jet coupler 10 has an inlet connector 11 located on the upstream side, an outlet connector 12 located on the downstream side, and an outlet connector 13 located on the inlet connector 11 and the outlet connector 14. The hollow portion 13 between the water outlet connectors 12 and the water inlet connector 11 contains a pressure-gathering pipe 111 coaxially connected to the water inlet connector 11. A jetting hole 112 is located at the front end of the pressure-gathering pipe 111. A pressure-relief pipe 121 coaxially connected to the water outlet connector 12 is located inside the water outlet connector 12. A receiving hole 122 coaxially opposite to the jetting hole 112 is located at the rear end of the pressure-relief pipe 121. The water inlet connector 11 is connected to the drinking water pipe network, and the drinking water supplied by the pipe network is amplified by the pressure-gathering pipe 111 on the upstream side. After pressure is applied, a smooth water jet is ejected from the spray hole 112. This smooth water jet passes through the perforated part 13 and enters the receiving hole 122 on the downstream side. After pressure reduction by the pressure relief pipe 121, it flows out through the water outlet connector 12. The water outlet connector 12 connects to the posterior wash spray rod and the feminine wash spray rod in the spray gun 30 to supply water to the posterior wash spray rod and the feminine wash spray rod. Two jet couplers 10 with perforated free jet channels in the middle are fastened in the housing 20. The exposed water inlet connector 11 and water outlet connector 12 are not included. By intermittently utilizing the pressure build-up and pressure release of the supplied water, the working water pressure of the downstream spray bar can be rebuilt, ensuring the stable operation of the spray bar. The hollowed-out part 13 on the upstream and downstream sides of the water inlet of the two spray bars provides space to block siphon backflow and ensure the safety of drinking water. Furthermore, this utility model has a simple structure, is quick to assemble, and is small in size and low in height. Its application benefits from the flattened design of the rear shell hinge seat of the bidet toilet cover, which makes the appearance of the bidet toilet cover more concise and beautiful.

[0025] The structure of each component of this utility model will be described below.

[0026] Reference Figures 1-2 , Figure 4 As shown, a baffle 14 is provided in the hollowed-out part 13 perpendicular to the direction of the smooth water column ejection. A through hole 141 is provided in the baffle 14, which is coaxially opposite to the spray hole 112 and the receiving hole 122. The smooth water column is ejected into the receiving hole 122 through the through hole 141. The jet coupler 10 forms a free flow channel in the hollowed-out part 13. The through hole 141 in the baffle 14 in the hollowed-out part 13 is used to shape the straight water column ejected from the spray hole 112. The water column of the upstream spray hole 112 is shaped by drilling through the through hole 141 and enters the receiving hole 122. Thus, the water pressure required for the operation of the water spray bar is re-established in the pressure relief pipe 121 and the water outlet connector 12 connected to the receiving hole 122. In this way, the possibility of sewage water flowing back to the upstream water supply side can be eliminated.

[0027] Reference Figures 1-2 As shown, at least one first semicircular portion 26 is provided on the rear side wall of the bottom shell 21, and a first semicircular portion 26 is provided on the rear side wall of the cover 22 to engage with the first semicircular portion 26 on the bottom shell 21. The water inlet connector 11 is placed on the first semicircular portion 26 of the bottom shell 21. When the cover 22 rotates to engage with the bottom shell 21, the first semicircular portion 26 on the cover 22 engages with the first semicircular portion 26 on the bottom shell 21, limiting the water inlet connector 11. There are two first semicircular portions 26 on both the bottom shell 21 and the cover 22, used to house two jet couplers 10. At least one second semicircular portion 27 is provided on the front side wall of the bottom shell 21. A second semicircular portion 27 is provided on the front side wall of the cover 22, which engages with the second semicircular portion 27 on the bottom shell 21. The water outlet connector 12 is placed on the second semicircular portion 27 of the bottom shell 21. When the cover 22 is rotated to engage with the bottom shell 21, the second semicircular portion 27 on the cover 22 engages with the second semicircular portion 27 on the bottom shell 21 to limit the water outlet connector 12. There are two second semicircular portions 27 on the bottom shell 21 and two second semicircular portions 27 on the cover 22, which are used to fix two jet couplers 10 in the container 20.

[0028] Reference Figures 1-2 As shown, the bottom shell 21 and the cover 22 are connected by several soft straps 23. In this embodiment, there are two soft straps 23. A spring piece 24 is provided in the middle of the outer wall of the cover 22 away from the soft straps 23. A slot 241 is provided in the spring piece 24. A protrusion 25 is provided in the middle of the outer wall of the bottom shell 21 away from the soft straps 23. When the cover 22 is rotated to fasten the bottom shell 21, the lower edge of the protrusion 25 presses against the bottom wall of the slot 241 to fix the cover 22 and the bottom shell 21. Due to the flexible material properties of the soft straps 23, it is easy for the bottom shell 21 and the cover 22 to be rotated and fastened. The protrusion 25 and the slot 241 limit and fix it, which facilitates opening and closing, and effectively prevents the jet coupler 10 from slipping and falling out of the container 20.

[0029] Reference Figures 1-2 , Figures 4-5 As shown, the top of the cover 22 has a concave arched plate 22.1, and the bottom of the bottom shell 21 has an inclined plate 28 that slopes from back to front. A drain hole 29 is provided at the bottom of the front side wall of the bottom shell 21. When the high-speed water jet is sprayed from the spray hole 112 on the upstream side of the jet coupler 10, water mist or a little splash will be generated at the orifice. The water mist or splash is blocked on the side of the hollow part 13 facing the spray hole 112 to prevent the receiving hole 122 from receiving the water jet from the spray hole 112 due to water splash or water mist. The water splash will fall onto the inclined plate 28 at the bottom of the box, or splash and adhere to the inner surface of the cover and accumulate. It is then guided by the arched plate 22.1 to the inclined plate 28, and then the residual water of the splash is collected and automatically flows to the drain hole 29 provided on the lower part of the bottom shell 21 under the guidance of the inclined plate 28 to be discharged, so as to prevent the accumulation of water mist or splash and thus affect the water supply to the spray gun 30.

[0030] The working principle and specific implementation steps of this utility model are explained in detail below.

[0031] Reference Figures 1-3 , Figure 5 As shown, the container 20 and the spray gun 30 are installed on the rear bottom plate 40 of the toilet seat. The two water lines are connected from the upstream side of the drinking water pipe network through two exposed water inlet connectors 11 on the container 20. The water inlet ends of the two spray rods on the spray gun 30 are connected to the two exposed water outlet connectors 12 on the container 20 through hoses 50. The drinking water supply is pressurized by the pressure-gathering pipe 111 on the upstream side and ejected from the spray hole 112 as a high-pressure water column. The high-pressure water column passes through the through hole 141 on the partition 14 and enters the receiving hole 122 on the downstream side. After being depressurized by the pressure relief pipe 121, it flows out through the water outlet connector 12 and is sprayed out by the two spray rods on the spray gun 30 to spray and wash the private parts of the human body. The upstream and downstream sides of the two spray rods are connected by a jet coupler 10 in the container 20 to prevent the water from the spray rods from being siphoned back to the tap water pipe network.

[0032] When the jet coupler 10 is working, the water mist, water droplets or water spray generated in the container 20 are poured out through the drain hole 29 in front of the container. The residual water discharged falls into the water receiving groove 41 and accumulates, and is discharged into the ceramic toilet bowl through the drain ditch 42.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
