Description

Technical Field

[0001] This utility model relates to the field of toilet technology, and in particular to a silent flushing toilet device. Background Technology

[0002] Toilets are a common bathroom product used in people's lives. They are widely used because people can sit directly on the toilet during the toilet process, which greatly relieves leg pressure.

[0003] In order to achieve better flushing effect, existing toilet devices usually have a siphon flushing pipe installed at the bottom of the toilet bowl where it connects to or transitions to the drain pipe, that is, at the water storage area at the bottom of the toilet bowl. This siphon flushing pipe works in conjunction with the flushing pipe of the main body of the toilet bowl to achieve efficient siphon flushing.

[0004] However, in practical applications, there may be a time discrepancy between the siphon flushing pipe and the main flushing pipe of the toilet bowl during the flushing process. Alternatively, during the flushing of the main flushing pipe of the toilet bowl, there may be a water gap between the flushing water and the siphon flushing water. The siphon flushing pipe may flush out a large amount of high-pressure water in a short period of time. The siphon flushing water may generate significant noise due to the intense friction between the siphon flushing water and the air and the inner wall of the sewage pipe. This can cause noise interference to users, especially in environments that require a relatively quiet environment. Summary of the Invention

[0005] The main purpose of this utility model is to propose a silent flushing toilet device, which aims to improve the noise reduction effect of the flushing process of the toilet device.

[0006] To achieve the above objectives, this utility model proposes a silent flushing toilet device. The toilet bowl has a hollow internal structure. A water tank is located on one side of the toilet bowl, and a flushing pipe inlet is located on the other side. The water outlet of the water tank is connected to a water pump through a first pipe. The water pump is also connected to the flushing pipe inlet through a second pipe. The flushing pipe inlet is connected to the flushing pipe outlet through a flushing pipe built into the toilet bowl. The bottom of the toilet bowl is connected to a drain pipe. When the drain pipe is not flushing, it stores a water seal. The flushing water flows through the flushing pipe outlet to the bottom of the toilet bowl. The flushing water compresses the water seal water and causes a siphon discharge phenomenon due to gravity.

[0007] Preferably, the volume of the water seal is V1, the volume of the flushing water inside the toilet bowl is V2, and the volume of the toilet bowl inside the toilet bowl is V3. <V2<V3。

[0008] Preferably, the transition structure between the sewage pipe and the main body of the toilet does not have a siphon flushing pipe for flushing water towards the sewage pipe.

[0009] Preferably, the outlet of the flushing pipe is located above the waste-receiving surface of the toilet body, and the inner wall of the toilet body is provided with a stepped groove. Part of the water discharged from the outlet of the flushing pipe moves along the surface of the stepped groove, and the other part of the water flows downward along the waste-receiving surface.

[0010] Preferably, the water moving along the contaminated surface falls into the drain hole at the bottom of the toilet body to form a first water layer, and the water moving along the stepped groove falls into the drain hole at the bottom of the toilet body to form a second water layer. The first water layer and the second water layer together drive the water seal to move.

[0011] Preferably, the water tank is located in the left side space inside the toilet bowl body and extends from back to front to the front space of the toilet bowl body; the water pump is located in the right side space inside the toilet bowl body.

[0012] Preferably, the outlet of the flushing pipe is located on the inner wall of the front part of the toilet body. After some water is discharged from the outlet of the flushing pipe, it flows along the sewage receiving surface and passes through the water seal and flows directly into the sewage pipe.

[0013] Preferably, the sewage receiving surface includes a first surface that is vertically opposite to the outlet of the flushing pipe, a second surface located at the front of the toilet body, and a third surface located on the right side of the toilet body. The slope of the second surface is greater than that of the third surface, and the boundary line between the second surface and the water seal gradually approaches the sewage pipe from right to left, with the slope of the boundary line being a fixed value.

[0014] Preferably, the inner side of the toilet bowl body extends from bottom to top.

[0015] The technical solution of this utility model has the following advantages over the prior art:

[0016] This utility model's technical solution uses a water pump to transport water from the tank to the outlet above the toilet bowl. During the flushing process, the water's own gravity is used to flush the inner wall of the toilet bowl in multiple ways and collect at the bottom. The large amount of flushing water can effectively push the water seal in the sewage pipe to the end, thereby triggering a siphon effect to achieve sewage discharge. This effectively avoids the noise generated by the high-pressure water flow from the siphon flushing pipe and the intense friction between the water and the air and pipe wall, which is a common feature in existing technologies. At the same time, it ensures the cleanliness of the flush and the sewage discharge effect, achieving a significant noise reduction. Attached Figure Description

[0025] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model proposes a silent flushing toilet device.

[0028] Please see Figure 1-4In this embodiment of the silent flushing toilet device, a toilet bowl body 1 is provided at the front of the toilet device, and an installation space is provided at the rear of the toilet device for installing a corresponding water tank structure. The internal structure of the toilet bowl body 1 is hollow, with a water tank 2 provided on one side of the toilet bowl body 1 and a flushing pipe inlet 3 provided on the other side of the toilet bowl body 1. The water tank inlet 2 can be externally installed or connected to a tap water source through a pipe. The water tank outlet 204 of the water tank 2 in this utility model is connected to a water pump 5 through a first pipe 4, and the water pump 5 is also connected to the flushing pipe inlet 3 through a second pipe 6. Therefore, when the water tank 2 is filled with water, the water is pumped towards the flushing pipe inlet 3 by the suction action of the water pump 5. Finally, the water flows from the flushing pipe outlet 301 to flush the soiled surface 101 of the toilet bowl body 1, so as to clean the excrement on the soiled surface 101 and collect it to the bottom. In addition, the bottom of the toilet bowl body 1 is connected to the drain pipe 7. Since the drain pipe 7 of this utility model is an S-shaped bend, a water-storing structure is provided at a specific position of the drain pipe 7. Specifically, the corresponding water-storing structure is located at the connection position between the drain pipe 7 and the bottom of the toilet bowl. The water-storing structure stores water, which can completely seal the ventilation cross section of part of the drain pipe 7, preventing odors from leaking out from the front end of the drain pipe 7. When the drain pipe 7 is not flushing, a water seal 702 is stored inside the drain pipe 7. When the flushing water flows through the flushing pipe outlet 301 to the bottom of the toilet bowl body 1, the flushing water can squeeze the water seal 702 through gravity and cause a siphon discharge phenomenon.

[0029] In order to achieve a more efficient siphon flushing effect, existing toilet devices usually have a corresponding siphon flushing pipe installed at the transition position between the drain pipe 7 and the toilet bowl body 1. That is, during the flushing process, the flushing pipe above discharges flushing water downwards, and the flushing water also flows towards the bottom of the toilet bowl body. At the same time, the siphon flushing pipe flushes water simultaneously, using a powerful flushing process in conjunction with the flushing water to achieve the siphon effect, so as to completely discharge the excrement inside the toilet bowl. However, this flushing process, because the siphon flushing discharges a powerful water body, is extremely prone to generating a lot of flushing noise.

[0030] Preferably, at the transition position between the sewage discharge pipe 7 and the toilet body 1 in the technical solution of the present utility model, there is no corresponding siphon flushing water pipeline for flushing towards the sewage discharge pipe. Therefore, in the flushing process of this embodiment, there is no need to adopt siphon flushing to trigger the siphon phenomenon. In the actual application process, only a large amount of water needs to be discharged from the water outlet 301 of the flushing water pipeline and quickly gather at the bottom of the toilet body 1. The water seal water body 702 is pushed towards the ground sewage outlet by the self-gravity of the flushing water body, so that the flushing water body and the water seal water body flow together in the internal space of the sewage discharge pipe 7, and finally the excrement is completely discharged, and the inner wall surface of the toilet body 1 can also be flushed clean.

[0031] Preferably, the volume of the water seal water body in the technical solution of the present utility model is V1, the volume of the flushing water body inside the toilet body 1 is V2, and the volume of the toilet basin accommodation inside the toilet body 1 is V3, where V1 < V2 < V3, so as to ensure that the flushing water body will not overflow outside the toilet body 1, and the flushing water body has sufficient flow or volume, even a large amount of flushing water body, which can flush the inner wall surface of the toilet body 1 clean and reliably discharge the water seal water body 702 completely through the sewage discharge pipe 7 to the outside.

[0032] More preferably, the water outlet 301 of the flushing water pipeline in the technical solution of the present utility model is arranged above the sewage receiving surface 101 of the toilet body 1, and a step groove 102 is provided on the inner wall surface of the toilet body 1. Part of the water discharged from the water outlet 301 of the flushing water pipeline moves along the surface of the step groove 102, and the other part of the water body flows downward along the sewage receiving surface 101 to achieve a diversion effect. And the water body moving along the sewage receiving surface 101 falls into the sewage discharge hole 701 at the bottom of the toilet body 1 to form a first water layer, and the water body moving along the step groove 102 falls into the sewage discharge hole 701 at the bottom of the toilet body 1 to form a second water layer. Through the above diversion effect, the flushing water body can not only flush the sewage receiving surface of the toilet body 1 clean, but also gradually enter the bottom position of the toilet body 1, so that the weight of the flushing water body increases in two stages, and the water seal water body 702 can be reliably pushed towards the end of the sewage discharge pipe 7 by gravity to start the siphon phenomenon and discharge the excrement. [[ID=IS]]

[0033] Please refer to Figure 1 、 34. Preferably, the water tank 2 of this invention is located in the left-side space inside the toilet bowl body 1, extending from back to front to the front cavity space of the toilet bowl body 1. The flushing pipe 302, which connects the inlet 3 and outlet 301 of the flushing pipe, is located on the right side of the toilet bowl body 1, following a path from the right rear to the left front. This arrangement fully utilizes the internal space of the toilet bowl body 1. The water pump 5 is located in the right-side space inside the toilet bowl body 1. Since the water tank 2 of this invention has a relatively large overall weight when filled with water, by placing the water pump 5 on the opposite side inside the toilet bowl body 1, the weight of the water pump 5 and the water tank 2 filled with water is relatively balanced and stable on both sides, ensuring a more reasonable internal structural distribution of the toilet device and relative weight balance.

[0034] Specifically, the water tank 2 of this utility model includes a water tank shell 201 and an inlet valve assembly 202. The inlet end of the inlet valve assembly 202 extends downward through the water tank shell 201 and is fixedly connected to the water tank shell 201 by a nut 203. The inlet end of the inlet valve assembly 202 is connected to an external pipeline to supply water. In addition, the interior of the water tank shell 201 is hollow, which can easily accommodate a relatively large amount of water. The bottom of the water tank shell 201 is provided with an outlet end connected to the first pipe 4 to realize the water pumping function.

[0035] Please see Figure 5 In other embodiments of this utility model, the water outlet 3 is located on the inner wall of the front part of the toilet body 1. After some water is discharged from the water outlet 301 of the flushing pipe, it flows directly into the sewage pipe 7 along the sewage receiving surface 101 and through the water seal 702. By directly entering the sewage pipe 7, the flow path length of some water is reduced, and the water seal 702 is directly pushed to the end of the sewage pipe 7 to start the corresponding siphon phenomenon. The other part of the water is flushed clean along the sewage receiving surface 101 of the toilet body 1.

[0036] Preferably, in other embodiments of this utility model, the waste-receiving surface 101 includes a first surface 103 connected to the water outlet, a second surface 104 disposed at the front of the toilet body 1, and a third surface 105 disposed on the right side of the toilet body. The slope of the second surface 104 is greater than that of the third surface 105, and the boundary line 106 between the second surface 104 and the water seal gradually approaches the drain pipe 7 from right to left with a fixed slope. Part of the water flows directly from the water outlet 3 to the drain outlet 701 at the end of the drain pipe 7, that is, it flows downward through the first surface 103. The other part of the water is flushed along the waste-receiving surface of the toilet body 1, flows along the stepped groove 102 and along the third surface 105 and the second surface 104. Because the second surface 104 has a larger slope and the boundary line 106 gradually approaches the drain pipe 7 from right to left, the water reaching the second surface 104 is concentrated and moves towards the drain pipe 7.

[0037] Preferably, the inner side 107 of the toilet bowl body of this utility model extends from bottom to top, or the inner side 107 of the toilet bowl body is a straight surface extending upwards, without grooves, to avoid dirt accumulation and achieve convenient cleaning effect.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
