Detailed Description

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following description of the present invention is provided with reference to the accompanying drawings, which are only some embodiments of the present invention, and it is obvious for a person skilled in the art to obtain other drawings without creative efforts.

As shown in fig. 1 to 4, an embodiment of the present invention provides a water tank drainage device with improved noise, which includes a water tank body 10 and a drainage valve 20 disposed in the water tank body 10, wherein the drainage valve 20 is used to open or close a drainage port 11 disposed on a bottom wall of the water tank body 10. The bottom wall of the cistern body 10 is further provided with a drainage channel 12 communicated with the drainage port 11, an outlet 121 of the drainage channel is formed on the side wall of the cistern body 10, and the drainage channel is transversely arranged, so that the overall height of the cistern body 10 can be reduced, and the low-profile design of the cistern body 10 is realized.

The tank drain further includes a sewer pipe 30, and the sewer pipe 30 communicates with the outlet 121 of the drainage passage to form a water flow path. The water in the tank body 10 flows down into the toilet (not shown) via the drainage channel 12, the sewer pipe 30 to flush the toilet.

The water tank drainage device also comprises an air supplementing channel 40, wherein the air supplementing channel 40 is communicated with the water flow path and the outside air, so that a small amount of air can be supplemented to the water flow path through the air supplementing channel 40 during drainage, the negative pressure formed by the water flow path during drainage is reduced, and the problem of high drainage noise caused by the fact that a large amount of air is sucked into the water flow path from the drainage port 11 is solved.

In this embodiment, the air supply passage 40 is formed in the water tank, and the inlet 42 of the air supply passage 40 is higher than the full water level of the water tank body 10 (the full water level is the water storage level when the water tank body 10 is not discharging water), so that the inlet 42 of the air supply passage 40 is always communicated with the outside air. Specifically, the sidewall of the outlet 121 of the water tank body 10 on which the drain passage is formed forms the sidewall of the air supply passage 40 to define the flow path of the air in the air supply passage 40, so that the structure inside the water tank body 10 is more compact, and the internal space of the water tank body 10 is saved.

In this embodiment, the outlet 41 of the aeration channel is oriented in the same direction as the outlet 121 of the drainage channel, so that the influence of the aeration air flow on the flow of the water flow can be minimized.

In this embodiment, the outlet 41 of the aeration passage is formed on the sidewall of the tank body 10 having the outlet 121 of the drain passage, and the outlet 41 of the aeration passage is located above the outlet 121 of the drain passage.

In this embodiment, the air supply passage 40 is further provided with a water replenishing connector 43, the water replenishing connector 43 is arranged at the top end of the air supply passage 40 and is arranged in parallel with the front and back of the inlet 42 of the air supply passage 40, the water replenishing connector 43 is communicated with a water inlet valve (not shown) arranged in the water tank, and water replenishing water flow from the water inlet valve replenishes water for the water seal of the toilet through the air supply passage 40, so that the structure in the water tank body 10 is more compact.

In this embodiment, an overflow pipe (not shown) is further disposed in the tank body 10, the overflow pipe is connected to the drainage channel 12, and the flow cross-sectional area of the air supply channel 40 is smaller than that of the overflow pipe. The overflow line may be provided on the drain valve 20 or may be provided independently of the drain valve 20. Preferably, in order to prevent air from being sucked into the water flow path from the overflow channel during the draining process, a control valve (not shown) for opening or closing the overflow channel may be provided, the control valve opening the overflow channel during the overflowing, i.e. the control valve is in the non-overflowing state (normal draining state) and the control valve closes the overflow channel, thereby preventing air from being sucked into the water flow path from the overflow channel during the normal draining state. The control valve can adopt a floating bucket structure or a water level sensor, when the control valve adopts the floating bucket structure, when the water level in the water tank body 10 rises to make the floating bucket float, the overflow pipeline is opened by the floating bucket, so that the water in the water tank body 10 can overflow away through the overflow pipeline, and when the water level in the water tank body 10 is at the normal water level, the floating bucket is always in the falling position and closes the overflow pipeline, thus avoiding the air from being sucked into the water flow path through the overflow pipeline.

In this embodiment, the sectional area of the inlet of the sewer pipe 30 is smaller than the sectional area of the outlet 121 of the drainage channel, so that when the drainage channel 12 drains water, the sewer pipe 30 can be filled with water flow as much as possible, and the drainage effect is better. Specifically, the sewer line 30 includes a horizontally disposed first pipe segment 31 and a turn pipe segment 32 connected to the water outlet end of the first pipe segment 31. As shown in fig. 4, the inner surface of the first pipe section 31 is tapered inward in the direction of water flow. The first tube section 31 includes a top wall, a bottom wall, a front wall and a rear wall, the inner surfaces of which are each formed with a non-linear arc 311. Of course, a non-linear arc surface may be formed only on the inner surface of the front wall or the rear wall, or a non-linear arc surface may be formed on the inner surface of the top wall and/or the bottom wall, in this embodiment. The resistance of the pipeline to water flow can be reduced by arranging the nonlinear cambered surface 311, so that the water flow velocity is larger.

As shown in fig. 2 and 3, fig. 2 is a longitudinal sectional view of the cistern drainage device when the cistern drainage device is not draining water, and fig. 3 is a longitudinal sectional view of the cistern drainage device when the cistern drainage device is draining water, during the drainage, the water in the cistern body 10 flows to the sewer pipe 30 through the drainage port 11 and the drainage channel 12, and then flows to the toilet for flushing, at the same time, because the water flow path formed by the drainage channel 12 and the sewer pipe 30 forms negative pressure, before the water level in the cistern body 10 has not dropped to the extent that air can enter the drainage port 11, the outside air enters the water flow path through the air supplement channel 40, so as to reduce the negative pressure of the water flow path, thus effectively avoiding the problem that a large amount of air is sucked into the drainage channel 12 from the drainage port 11 and causes loud noise when the water level in the cistern body 10 continues to drop to.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
