[0049] The sink assembly provided by the utility model can be used as a vegetable washing basin in the kitchen. The sink assembly comprises a sink body 1, a plurality of water spray modules 2, a first control valve 3, a second control valve 4 and the like.

[0050] The water tank body 1 includes a bottom plate 11 and a tank wall 12 . A plurality of mounting openings 121 are provided on the tank wall 12 for mounting the water spray module 2 .

[0051] The water spray module 2 is used to spray water into the water tank body 1 for the user to wash dishes, vegetables, etc. There are multiple water spray modules 2 spaced apart on the tank wall 12. The "multiple" referred to in the utility model refers to more than two. Preferably, a water spray module 2 is respectively installed on the tank wall 12 on the left and right sides of the water tank body 1.

[0052] The first control valve 3 is used to control the water circuit switch for supplying water to the water spray module 2, adjust the water temperature, adjust the water flow, etc. The first control valve 3 can be a conventional mechanical valve or a solenoid valve.

[0053] The first control valve 3 includes a cold water inlet 31, a hot water inlet 32 ​​and a water outlet 33. The cold water inlet 31 is used to connect to the cold water pipe 100, the hot water inlet 32 ​​is used to connect to the hot water pipe 200, and the water outlet 33 is used to connect to the water pipe 5. The first control valve 3 can control the flow of cold water and hot water to control the water circuit switch, adjust the water temperature, and adjust the water flow. Water is transported to the second control valve 4 through the water pipe 5.

[0054] The second control valve 4 is used to control the switch of each water spray module 2, for example, to open a water spray module 2 alone, or to open multiple water spray modules 2 at the same time. The second control valve 4 can be a traditional mechanical valve or a solenoid valve. The second control valve 4 has multiple gears, each of which controls a water outlet mode.

Each second water outlet 43 of the second control valve 4 is respectively connected to a water spray module 2 through a second water supply pipe 7, that is, the plurality of water spray modules 2 and the plurality of second water outlets 43 are respectively connected one-to-one through the plurality of second water supply pipes 7.

[0056] The second control valve 4 has a first gear position and a plurality of second gear positions, and correspondingly the water spray module 2 has a first water outlet mode and a second water outlet mode.

[0057] When the user selects the first gear, the first water outlet 42 is opened, the second water outlet 43 is closed, and the multiple water spray modules 2 discharge water at the same time, providing a simultaneous water discharge mode.

[0058] When the user selects a second gear, one of the second water outlets 43 is opened, and the other second water outlets 43 and the first water outlet 42 are closed, and only one water spray module 2 discharges water, providing a single-side water outlet mode.

[0059] For example, when a water spray module 2 is provided on the left and right sides of the water tank body 1, the second control valve 4 has two second gears. When the user selects one second gear, the water spray module 2 on the left side discharges water; when the user selects another second gear, the water spray module 2 on the right side discharges water.

[0060] Therefore, the sink assembly provided by the utility model utilizes the first control valve 3 to adjust the water temperature, adjust the flow rate and control the water circuit switch, and utilizes the second control valve 4 to control one or more water spray modules 2, which can realize both single-sided flushing and multi-sided flushing, enriching the flushing function of the product and improving the user experience.

[0064] In one embodiment, if Figure 5 As shown, the water spray module 2 is integrated with an overflow pipe 24 for discharging water in the water tank body 1 that is higher than the safe water level to the downpipe of the water tank body 1. The overflow pipe 24 is integrated in the water spray module 2, so there is no need to open an overflow hole and install an overflow pipe on the tank wall 12, which optimizes the appearance of the water tank body 1 and facilitates installation.

[0065] In one embodiment, if Figure 5-11 As shown, the water spray module 2 includes a module housing 21 , a water spray mechanism 22 and a water inlet pipe 23 .

[0066] The module shell 21 is connected to the tank wall 12 . The module shell 21 is provided with a shell cavity 211 opening toward the inner side of the tank body 1 .

[0067] The water spray mechanism 22 is detachably installed in the housing cavity 211 .

[0068] The water inlet pipe 23 is connected to the module housing 21 and communicates with the water inlet end of the water spraying mechanism 22 .

[0069] The first water supply pipe 6 and the second water supply pipe 7 are respectively connected to the water inlet pipe 23 .

[0075] When the user needs to store water in the water tank body 1, the plug cover covers the drain port on the bottom plate 11 of the water tank body 1. If the water level in the water tank body 1 is higher than the overflow hole 2113, the excess water will flow into the overflow pipe 24 through the overflow hole 2113, and then flow into the drain pipe of the water tank body 1 from the overflow pipe 24, and finally be discharged to the building drainage pipe.

[0076] Preferably, the water spray mechanism 22 is higher than the overflow hole 2113. That is, the water outlet of the water spray mechanism 22 is higher than the overflow hole 2113. When the water in the water tank body 1 reaches the height of the overflow hole 2113, the water outlet of the water spray mechanism 22 sprays water into the water tank body 1 at a height higher than the overflow hole 2113, and will not directly hinder the water flow toward the overflow hole 2113, which is conducive to maintaining the anti-overflow function of the water tank body 1.

The overflow hole 2113 is provided on the wall surface of the overflow cavity 2112, and the wall surface includes the bottom surface and the side surface of the overflow cavity 2112. The water inlet end of the overflow pipe 24 is connected to the overflow hole 2113, so as to communicate with the overflow cavity 2112.
