Description

Technical Field

[0001] The invention relates to a flushing system of a single pressure barrel and a toilet. Background Art

[0002] Among domestic and foreign sanitary ware products, existing pressure flush toilets currently basically adopt the form of double pressure barrels, that is, a pressure barrel is placed on each side of the siphon tube at the water tank position on the rear side of the ceramic seat body. In order to be able to place such a pressure barrel, the width of the matching ceramic seat body needs to be made relatively wide. The upper and lower widths are not much different in appearance, and it looks very bulky, resulting in many restrictions on the appearance design of the ceramic seat body, and it is impossible to make a beautiful toilet that meets market demand.

[0003] In addition, the design of two pressure barrels occupies a large space at the rear of the ceramic due to the water inlet valve and flush valve. This is fine for floor-standing toilets, but for wall-mounted toilets that have height requirements for ceramics: there are many difficulties in production and assembly, resulting in very low efficiency, and for terminal bathrooms, when wall-mounted toilets are installed, it is very inconvenient to connect water and electricity, especially for the solution of concealed installation of water and electricity behind the toilet. Because the space is too small, the operating space for the angle valve switch is very small, and it is very inconvenient during later maintenance, and the wall may need to be broken, which brings great trouble and living costs to consumers. Summary of the invention

[0004] In order to solve the above technical problems, the object of the present invention is to provide a flushing system and a toilet with a single pressure barrel.

[0005] The present invention is achieved through the following technical solutions:

[0007] In the embodiment of the present invention, a pressure stabilizing valve is provided between the water inlet end of the water inlet valve assembly and the water inlet hose.

[0008] In an embodiment of the present invention, the water inlet valve group further includes a vacuum breaker.

[0009] In the embodiment of the present invention, the first water outlet group further includes a first solenoid valve, and the first solenoid valve is arranged between the first water outlet end of the water inlet valve group and the first water outlet pipe.

[0030] Referring to the drawings of the specification, a flushing system for a single pressure barrel includes: a water inlet valve group 20, the water inlet end of the water inlet valve group is connected to a water source via a water inlet hose 11, the water source referred to here can be municipal water, which is normally connected to the angle valve of the cavity; a first water outlet group 30, the first water outlet group includes a first nozzle 31 and a first water outlet pipe 32 connected, the water inlet end of the first water outlet pipe can be connected to the first water outlet end of the water inlet valve group, the water outlet end of the first water outlet pipe can be connected to the water inlet end of the first nozzle, in normal use, the first nozzle is an upper water outlet, and spiral water is formed in the seat body; a pressure barrel 40, the water inlet end of the pressure barrel is connected to the second water outlet end of the water inlet valve group; a second water outlet group 50, the second water outlet group includes a second nozzle 51 and a second water outlet pipe 52 connected, the water inlet end of the second water outlet pipe can be connected to the water outlet end of the pressure barrel, and the water outlet end of the second water outlet pipe can be connected to the water inlet end of the second nozzle. In one use, the first water outlet end of the water inlet valve group is for horizontal water outlet, and the second water outlet end of the water inlet valve group is for vertical water outlet.

[0031] Preferably, a pressure stabilizing valve 10 is provided between the water inlet end of the water inlet valve group and the water inlet hose. The water inlet valve group also includes a vacuum breaker 21. Of course, the water inlet valve group also includes a main component: a water inlet valve.

[0032] Furthermore, the first water outlet group further comprises a first electromagnetic valve 33, which is arranged between the first water outlet end of the water inlet valve group and the first water outlet pipe.

The second water outlet end of the water inlet valve group is located at the lower end of the water inlet valve group.

[0034] The present invention also discloses another technical feature:

[0035] A toilet comprises the above-mentioned single pressure barrel flushing system.

[0036] The seat body 60 is also included. A siphon tube 61 is arranged in the middle of the rear side of the seat body. Installation spaces 62 are formed in the seat body on both sides of the siphon tube. The pressure barrel is arranged in any installation space.

[0037] Preferably, an upper water spray port 63 is also provided on the upper side of the seat body, the first nozzle can be connected with the upper water outlet to form a spiral water flushing, and a lower water spray port that can be matched with the siphon is also provided on the lower side of the seat body, the second nozzle can be connected with the lower water spray port to form a straight water flushing to discharge the dirt from the siphon; the upper water spray port is located on the seat body on the side where the pressure barrel is installed, and the second water outlet can be connected with the lower water spray port after passing through the installation space on the other side. In other words, the pressure barrel and the upper water spray port are located on the same side of the seat body, and the water inlet end of the second water outlet pipe is connected with the pressure barrel on one side of the seat body, and then goes around the installation space on the other side of the seat body and is connected with the lower water spray port, and the second solenoid valve can also be set in the installation space on the other side, and the lower water spray port 64 is located in the middle of the seat body, facing the siphon, which is consistent with the prior art and will not be elaborated in detail here. At the same time, the water inlet hose can be connected to water from the installation space on the other side of the seat body and then flow to the installation space on one side of the seat body. Because the installation space on the other side of the seat body is less utilized, it is easy to operate.

[0038] The present invention innovatively designs a single pressure barrel flushing system, which has only one single tank, plus two solenoid valves, and no other water tanks; one pressure barrel is only used to spray under the toilet to produce siphon, and the first nozzle is cleaned by tap water, and two solenoid valves are used to control the opening at different times. This ensures that the system cost is reduced as much as possible, while ensuring a strong toilet flushing force and full recovery of the toilet water seal; and the single pressure barrel is smaller, which is more suitable for promotion and application to wall-mounted toilets, and the angle valve is more convenient to be concealed behind the ceramic; the ceramic does not need to be modified, and can be directly replaced with a single tank system for installation.

[0039] The present invention specifically states: a pressure flushing system with a single pressure barrel, comprising a single-tank pressure barrel, a water inlet valve group with a vacuum breaker, a pressure regulating valve, a first water outlet group, and a second water outlet group; the single-tank pressure barrel is fixedly installed in the installation space at the bottom of any one side of the ceramic; the water inlet valve group with a vacuum breaker is the only water inlet channel of the system, and has an anti-siphon function that meets national standards; the pressure regulating valve is installed at the front end of the water inlet valve group to control the water pressure entering the system within a set range; the first water outlet group comprises a first solenoid valve, a first nozzle and a first water outlet pipe in the middle, the front end of the first solenoid valve is connected to the first water outlet end of the water inlet valve group, and the rear end of the first solenoid valve is connected to the first nozzle through the first water outlet pipe; the second water outlet group comprises a second solenoid valve, a second nozzle and a second water outlet pipe, the front end of the second solenoid valve is connected to the water outlet end of the pressure barrel, and the rear end of the second solenoid valve is connected to the second nozzle. The main features of the matching toilet are: the toilet is a water tankless ceramic toilet, which is not much different from an ordinary smart toilet in appearance; the toilet has a siphon, as well as an upper water spray outlet and a lower water spray outlet; the toilet can be a floor-standing siphon toilet or a wall-mounted siphon toilet, especially a wall-mounted siphon toilet is more advantageous in matching with the main body system, and can effectively utilize a single pressure barrel to occupy a small installation space.

[0040] In the present invention, water from a single pressure barrel is only supplied to the lower outlet of the toilet; the upper outlet is directly derived from the impact of tap water; the water inlet valve group with a vacuum breaker is the total water inlet, ensuring that the system meets the overall requirements of national standard anti-siphonage; the pressure-stabilizing valve installed in front of the water inlet valve group not only ensures that the force of the lower jet water outlet is sufficient but also that the high pressure does not cause noise, but the water flow of the first water outlet pipe also passes through the pressure-stabilizing valve, ensuring that the upper outlet will not splash due to the high water pressure of tap water; two solenoid valves control the upper and lower water outlets respectively, and the upper and lower water outlet times are controlled by programming the circuit board inside the cover plate; ensuring that any ceramic water seal is fully restored, meeting the stable requirements of mass production.

[0041] The above description shows and describes the preferred embodiments of the present invention. As mentioned above, it should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the invention concept described herein through the above teachings or the technology or knowledge of the relevant field.
