Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchen and bathroom appliances technology, and in particular to a sink wall cleaning device and a sink. Background Technology
[0002] Currently, there are few solutions for flushing sanitary ware with water storage chambers on the market, such as sinks. The bottom of the sink, in particular, is prone to dirt accumulation due to its low position. The common practice is to manually rinse the bottom of the sink using a pull-out shower head, but this method is time-consuming and labor-intensive, requiring overcoming the weight of the plumb bob on the shower head hose, the limited length of the hose, and water splashing during operation. One existing technology for sinks with integrated flushing features uses several flushing holes arranged around the upper perimeter of the sink. Water from these holes flows from the sidewalls to the bottom of the sink for rinsing. However, multiple water flows interfere with each other, resulting in poor cleaning of the bottom of the sink. Furthermore, the multiple water outlets need to be fitted and sealed to the sidewalls of the sink, requiring high manufacturing precision. When the sink's dimensions change, the number and position of the water outlets also change, resulting in low versatility. Multiple water outlets also increase the probability of leakage and make repairs difficult. Utility Model Content

The water outlet connector 2 is rotated to align and snap the slot 212 and the retaining edge 203. Specifically, there are two slots 212, which are arranged opposite each other on the left and right sides of the outer side of the end of the water outlet connector 2 with the water inlet 211. There are also two retaining edges 203, which are formed by the edges of the left and right sides of the mounting hole 202. The slot 212 has a snap-fit inlet 213 at one end and a rotation limit edge 214 at the other end to prevent over-rotation.
[0047] The mounting base 1 is connected to the mounting part 208 via fasteners. The fasteners include screws 3. The mounting base 1 is provided with threaded holes 12, and the mounting part 208 is provided with connecting holes 204 corresponding to the threaded holes 12. The screws 3 pass through the connecting holes 204 from inside the water storage cavity 201 and are threadedly connected to the threaded holes 12.
[0048] The main body of the device also includes a cover plate 4, which is located in the water storage cavity 201 and connected to the installation part 208 and / or the water outlet connector 2.

A clearance gap 8 is provided between the cover plate 4 and the side wall where the installation part 208 is located, corresponding to the fan-shaped water outlet 23, so that the sanitary ware is more aesthetically pleasing. In this embodiment, the cover plate 4 is connected to the water outlet connector 2. Specifically, one side of the cover plate 4 has a locking protrusion 42, and the guide plate 22 has a locking hole 223 corresponding to the locking protrusion 42. The cover plate 4 is locked onto the guide plate 22 by the locking protrusion 42 and the guide plate 22. The cover plate 4 also has a limiting post 41 on one side, and the water outlet connector 2 has a through hole corresponding to the limiting post 41. That is, the connector body 21 has a through hole 215, the guide plate 22 has a through hole 222, and the mounting part 208 has an anti-rotation hole 205 corresponding to the limiting post 41. The limiting post 41 passes through the through hole 215, 222 and the anti-rotation hole 205 in sequence to prevent rotation, so that after the water outlet connector 2 is locked onto the mounting part 208 by rotation, the rotation of the water outlet connector 2 is restricted relative to the mounting part 208.
[0049] The fixed base 1 is also provided with an overflow chamber 13, which is provided with an overflow outlet 14 that is connected to the overflow pipe 40.

Specifically, the mounting part 208 is provided with an overflow inlet 206, which is connected to the overflow chamber 13 and the overflow gap 5. The fixed base 1 is also provided with an overflow channel 15, which is connected to the overflow outlet 14 and the overflow pipe 40 at both ends.
[0050] The main body of the device is centrally located on the side wall where the mounting part 208 is located in the horizontal direction. The maximum water outlet width of the fan-shaped outlet 23 (i.e. the maximum coverage area of the water flow on the side wall where the mounting part 208 is located in the horizontal direction) is greater than or equal to the dimension of the side wall where the mounting part 208 is located in the horizontal direction.
[0051] The sidewall of the water storage cavity 201 is provided with a groove 207, the bottom of which forms a mounting portion 208, and the water outlet connector 2 is partially accommodated within the groove 207. When the water outlet connector 2 is installed in the mounting portion 208, the connector body 21 is nearly flush with the sidewall of the mounting portion 208, and the fan-shaped water outlet 23 protrudes slightly from the sidewall, allowing the fan-shaped sheet of water to flow along the sidewall of the mounting portion 208. In other embodiments, the mounting portion 208 may also be coplanar with its sidewall, with the fan-shaped water outlet 23 inclined towards the sidewall of the mounting portion 208, allowing the fan-shaped sheet of water to flow along the sidewall of the mounting portion 208.
[0052] The installation process of this utility model for a tank wall cleaning device is as follows: First, place the fixing base 1 on the outside of the sanitary fixture, and thread the screw 3 through the connecting hole 204 from inside the water storage cavity 201 to the threaded hole 12, thus completing the installation of the fixing base 1. Then, place the water outlet connector 2 inside the water storage cavity 201, with the two slots 212 of the water outlet connector 2 facing up and down, and the fan-shaped water outlet 23 facing to the right. Then, pass the end of the water outlet connector 2 with the water inlet 211 through the mounting hole 202 and fit it onto the outside of the water outlet end of the water inlet channel 11. Figure 6 , 7 As shown, at this time along Figure 6 Rotate the water outlet connector 2 in the direction of the arrow so that the retaining edge 203 engages with the retaining groove 212 from the retaining inlet 213 until the retaining edge 203 abuts against the rotation limit edge 214, thus completing the installation of the water outlet connector 2. Figure 8 , 9 As shown, at this time, the fan-shaped water outlet 23 faces the bottom wall of the water storage cavity 201. Finally, the cover plate 4 is snapped into the guide plate 22, and the limiting post 41 of the cover plate 4 is sequentially passed through the through holes 215, 222 and the anti-rotation hole 205 of the water outlet connector 2 to prevent rotation, so that the cover plate 4 covers the water outlet connector 2 and the groove 207.
[0053] This utility model discloses a tank wall cleaning device that can rinse the side wall of the water storage cavity 201 of a sanitary ware with the mounting part 208 and the bottom wall of the water storage cavity 201. The fan-shaped water can cover a larger area and avoid the interference of multiple water streams in the prior art, significantly improving the cleaning effect of the bottom wall of the water storage cavity 201. At the same time, the modular design of the fixing base 1 and the water outlet connector 2 can be adapted to sanitary ware of different specifications, which is highly versatile and can also avoid the risk of leakage in multiple holes in the prior art.
[0054] This utility model provides a tank wall cleaning device that can rinse the bottom wall of the water storage cavity 201 and also rinse tableware and other items inside the water storage cavity 201. It also has an overflow function to prevent the water level from getting too high.
[0055] Please see Figures 1-14As shown, a water tank according to this utility model includes a tank body 20, which has a water storage cavity 201. The water storage cavity 201 is square, and at least one mounting hole 202 is provided on the side wall of the water storage cavity 201. In this embodiment, the number of mounting holes 202 is one. The aforementioned tank wall cleaning device 10 is installed in the mounting hole 202.
[0056] The bottom wall of the water storage cavity 201, at the end closest to the tank wall cleaning device 10, is vertically higher than the end furthest from the tank wall cleaning device 10, and a drain outlet is provided at the end of the bottom wall of the water storage cavity 201 furthest from the tank wall cleaning device 10. The water inlet channel 11 of the fixed base 1 is connected to the water inlet pipe 30.
[0057] This utility model provides a water tank that, when filled with water, such as... Figure 12 , 13 As shown, water flows out from the fan-shaped outlet 23 through the inlet pipe 30 and inlet channel 11, as... Figure 13 As shown, the maximum horizontal coverage area of the water flow on the side wall where the mounting hole 202 is located is greater than the maximum horizontal coverage area of the water flow on the side wall where the mounting hole 202 is located. Therefore, the water flow can cover the width of the bottom wall of the water storage cavity 201. Since the end of the bottom wall of the water storage cavity 201 closest to the tank wall cleaning device 10 is vertically higher than the end furthest from the tank wall cleaning device 10, when the water flows to the bottom wall of the water storage cavity 201, the water flow can be accelerated a second time by the use of potential energy, maintaining a certain speed from the end of the bottom wall closest to the tank wall cleaning device 10 to the end furthest from the tank wall cleaning device 10, and flowing into the drain outlet, completing the cleaning of the bottom wall of the water storage cavity 201; during overflow, as... Figure 14 As shown, the water in the water storage cavity 201 flows through the overflow gap 5 and the overflow inlet 206 into the overflow chamber 13, then flows from the overflow outlet 14 to the overflow channel 15, and then is discharged from the overflow pipe 40.
[0058] The structure and working principle of the tank wall cleaning device of this utility model are described in the preceding section and will not be repeated here.
[0059] Example 2
[0060] Please see Figure 15 As shown, the tank wall cleaning device and water tank of this utility model are different from the first embodiment in that the fixed base 1 of this embodiment is only provided with a water inlet channel 11, which is connected to the water inlet pipe 30, and no overflow channel is provided. That is, this embodiment only has the function of water inlet rinsing and does not have the function of overflow.
