Description

Technical Field

[0001] This utility model relates to a toilet and its flushing water supply device, and more particularly to a flush toilet and its flushing water supply device. Background Technology

[0002] The water tank of the toilet is higher than the ceramic body. The water stored in the tank has higher potential energy, which can meet the flushing requirements after being released. For example, the ceramic tank is connected to the upper rear of the ceramic body, or the tank is hung high on the wall, or the tank is installed in a cabinet and then embedded in the wall. Of course, the tank will require more installation space.

[0003] To save installation space, designers considered installing the tank within the ceramic body. However, this reduced tank height directly eliminates the advantage of flushing water potential energy, failing to meet flushing requirements. Therefore, a water pump is needed to increase the flushing water's energy. However, due to the inherent gaps in the ceramic body, the tank's volume is limited. To achieve effective flushing with a smaller water volume, the pump's power must be increased. Consequently, the current structure with the tank installed within the ceramic body results in a high-powered pump, leading to higher manufacturing and energy costs for the toilet. Utility Model Content

[0004] This utility model provides a toilet and its flushing water supply device, which overcomes the shortcomings of the prior art. The technical solution adopted by this utility model to solve its technical problem is as follows:

[0005] The toilet includes a ceramic body and a flushing water supply device. The front of the upper surface of the ceramic body is recessed to form a toilet bowl, and the rear of the upper surface of the ceramic body is recessed to form a cavity. The flushing water supply device includes a water tank and a water pump. The water tank is located within the cavity. When the water pump is activated, it pumps water from the water tank into the toilet bowl to flush it. The flushing water supply device also includes a secondary water tank, which is located at the bottom of the ceramic body and surrounds the outside of the toilet bowl. The height of the secondary water tank is less than the height of the main water tank. The inlet of the secondary water tank is connected to the outlet at the bottom of the main water tank via a first pipe, and the outlet of the secondary water tank is connected to the inlet of the water pump via a second pipe. The outlet of the water pump is connected to the ceramic body via a third pipe.

[0006] In a preferred embodiment: the top of the auxiliary water tank is provided with an air hole, the air hole is connected to an exhaust pipe, the upper end of the exhaust pipe extends upward and is higher than the overflow water level of the water tank, and the auxiliary water tank is a closed structure except for its inlet, outlet and air hole.

[0007] In a preferred embodiment: the middle part of the pipe is an upwardly convex arched structure, and the arched structure is provided with a drain hole. The height of the drain hole is higher than the upper surface of the ceramic body or the overflow water level of the toilet bowl.

[0008] In a preferred embodiment: an overflow outlet is provided on the upper edge of the rear side wall of the toilet bowl; an overflow guide channel is provided on the upper edge of the side wall of the water tank facing the toilet bowl; the overflow guide channel is attached to the overflow outlet; and a hanging plate is provided on the upper edge of the side wall of the water tank away from the toilet bowl; the hanging plate is attached to the ceramic body.

[0009] In a preferred embodiment: the auxiliary water tank is U-shaped with its opening facing the water tank and has an arc surface that fits the outer wall of the toilet bowl; the ceramic body is provided with a vortex flushing channel around the upper part of the toilet bowl, the pipe is connected to the vortex flushing channel, and the toilet is a washdown toilet.

[0010] The toilet flushing water supply device includes a water tank and a water pump for pumping water from the water tank into the toilet bowl of the ceramic body. It also includes an auxiliary water tank, the height of which is less than that of the water tank. The inlet of the auxiliary water tank is connected to the outlet at the bottom of the water tank through a pipe one. The outlet of the auxiliary water tank is connected to the inlet of the water pump through a pipe two. The outlet of the water pump is connected to a pipe three. The outlet end of the pipe three is used to connect to the ceramic body.

[0011] In a preferred embodiment: the top of the auxiliary water tank is provided with an air hole, the air hole is connected to an exhaust pipe, the upper end of the exhaust pipe extends upward and is higher than the overflow water level of the water tank, and the auxiliary water tank is a closed structure except for its inlet, outlet and exhaust hole.

[0012] In a preferred embodiment: a buckle is provided on the upper end of the side wall of the water tank, and the upper end of the exhaust pipe is fastened to the buckle.

[0013] In a preferred embodiment: the middle part of the pipe is an upwardly convex arched structure, and the arched structure is provided with a drain hole, the height of which is higher than the upper surface of the ceramic body or the overflow water level of the toilet bowl.

[0014] In a preferred embodiment: the arched structure of the middle part of the pipe extends toward the water tank and is provided with an extension end; the drain hole is located at the bottom of the extension end and directly above the water tank; and the bottom wall of the extension end is provided with a water-blocking rib inside the drain hole.

[0015] Compared with the prior art, this technical solution has the following advantages:

[0016] 1. The water tank, auxiliary water tank, and water pump are connected in sequence. After the water pump is started, it can draw water from the water tank and auxiliary water tank into the ceramic body to flush the toilet bowl, thereby increasing the flushing water volume of the toilet. Therefore, a low-power model of water pump can be selected to save manufacturing and operating costs. At the same time, the auxiliary water tank is small in height, and the space between the toilet bowl and the water tank at the bottom of the ceramic body effectively maintains the compactness of the toilet structure.

[0017] 2. The top of the auxiliary water tank is equipped with an air vent. During the water replenishment process, the internal gas can be discharged through the air vent to ensure that the auxiliary water tank is full of water.

[0018] 3. The middle part of pipe three arches upwards, so that the drain hole is higher than the upper surface of the ceramic body or the overflow water level of the toilet bowl. After the water pump stops working, air can enter pipe three through the drain hole, preventing the siphon phenomenon in pipe three from causing water in the water tank and auxiliary water tank to be automatically sucked into the ceramic body. At the same time, it can also prevent the sewage level in the toilet bowl from rising and backflowing into pipe three after the toilet is blocked, thus preventing the siphon phenomenon.

[0019] 4. The water tank is directly suspended from the ceramic body through an overflow channel and a hanging plate, resulting in a simple structure.

[0020] 5. The auxiliary water tank is made by blow molding, which can flexibly design its shape according to the internal space of the ceramic body, so as to better fit the toilet bowl and maximize the use of the extra space inside the ceramic body.

[0021] 6. The drain hole is positioned directly above the water tank at the extension end. When the water pump is working, a very small amount of water is discharged back into the water tank through the drain hole to avoid water waste. The baffle rib can also prevent water from flowing to other positions along the surface of the pipe. Attached Figure Description

[0032] Please refer to Figures 1 to 9 The toilet includes a ceramic body 10 and a flushing water supply device 20. A bowl 12 is recessed at the front of the upper surface of the ceramic body 10, and a cavity 14 is recessed at the rear of the upper surface. The flushing water supply device 20 includes a water tank 21 and a water pump 22. The water tank 21 is disposed within the cavity 14. When the water pump 22 is activated, it pumps water from the water tank 21 into the bowl 12 to flush the bowl. The flushing water supply device 20 also includes a secondary water tank 23, which is disposed at the bottom of the ceramic body 10 and surrounds the outer side of the bowl 12. In other words, the secondary water tank 23 is disposed around the bowl 12 of the ceramic body 10. The height of the secondary water tank 23 is less than the height of the water tank 21. In this embodiment, the top of the secondary water tank 23 rests against the outer wall of the bowl 12. The inlet of the auxiliary water tank 23 is connected to the outlet at the bottom of the water tank 21 via pipe 1 24, the outlet of the auxiliary water tank 23 is connected to the inlet of the water pump 22 via pipe 25, and the outlet of the water pump 22 is connected to the ceramic body 10 via pipe 3 26.

[0033] When the toilet inlet valve is opened, water automatically fills the water tank 21, first filling the auxiliary water tank 23. When the liquid level in the water tank 21 reaches the working water level, the inlet valve closes. The working water level in the tank is the liquid level when the inlet valve is closed. When the toilet is flushed, the water pump 22 is turned on, and the water pump pumps the water from the auxiliary water tank 23 and the water tank 21 into the toilet bowl 12 of the ceramic body 10. Understandably, pipes 24, 25, and 26 are used for water transmission. As long as the water flow direction can be controlled, they can be a single pipe, multiple pipes joined together, or two pipes with a transfer structure in between. For example, pipe 3 consists of two pipes connected by a silencer box or anti-siphon box; all of these can be called pipe 3.

[0034] Preferably, the auxiliary water tank 23 has an air vent at its top, which is connected to an exhaust pipe 27. The upper end of the exhaust pipe 27 extends upward and is higher than the overflow level of the water tank 21 (i.e., the water level that overflows after the water tank is full). The auxiliary water tank 23 is a sealed structure except for its inlet, outlet, and air vent. More preferably, the auxiliary water tank 23 is blow-molded.

[0035] Preferably, the upper end of the side wall of the water tank 21 is provided with a buckle 216, and the upper end of the exhaust pipe 27 is fastened to the buckle 216.

[0036] Preferably, the middle part of the pipe 26 is an upward-protruding arched structure 262. That is, following the direction of water flow, the pipe 26 first rises, passes its highest point, and then descends before connecting to the ceramic body 10. The arched structure 262 is designed to ensure that the highest point of the pipe 26 is higher than the water inlet of the ceramic body 10. Simultaneously, the arched structure 262 is provided with a drain hole 264 that communicates with the atmosphere. The height of the drain hole 264 is higher than the upper surface of the ceramic body 10 or the overflow water level of the toilet bowl 12 (i.e., the plane where water overflows after the toilet bowl is full). The drain hole 264 communicates with the atmosphere, allowing air to enter the pipe 26, thus disrupting its seal and preventing siphoning. During flushing, water flows from the pipe 26 into the ceramic body 10, with only a very small amount of water flowing out from the drain hole 264.

[0037] More preferably, the arched structure 262 in the middle section of the pipe three extends towards the water tank 21, forming an extension end 266. The drain hole 264 is located at the bottom of the extension end and directly above the water tank 21, allowing water to flow from the drain hole 264 into the water tank 21. More preferably, the bottom wall of the extension end 266 is provided with a water-blocking rib 268 inside the drain hole. The water-blocking rib 268 intercepts the water flow, preventing it from continuously spreading along the outer wall of the pipe three.

[0038] Preferably, an overflow outlet 16 is provided on the upper edge of the rear sidewall of the toilet bowl 12, and an overflow guide channel 212 is provided on the upper edge of the sidewall of the water tank 21 facing the toilet bowl. The overflow guide channel 212 is attached to the overflow outlet 16. A hanging plate 214 is provided on the upper edge of the sidewall of the water tank 21 facing away from the toilet bowl. The hanging plate is attached to the upper surface of the ceramic body 10. Alternatively, the hanging plate 214 can be attached to a step on the inner wall of the ceramic body 10, but attachment to the upper surface is preferred.

[0039] Preferably, the auxiliary water tank 23 is U-shaped, with its opening facing the water tank 21, and has an arc surface that conforms to the outer wall of the toilet bowl 12. The inlet and outlet of the auxiliary water tank are located at both ends of the U-shape.

[0040] Preferably, the ceramic body 10 is provided with a vortex flushing channel around the upper part of the toilet bowl 12, and the pipe 26 is connected to the vortex flushing channel. Therefore, the toilet is a washdown toilet.

[0041] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model patent and the contents of the specification should still fall within the scope of the present utility model.
