Because the radius of the fixing foot 71 is not greater than the radius of the embedded groove 31, the sink 200 can be lifted out of the cabinet body 100, achieving disassembly. The installation and disassembly process is simple, the structure is stable after installation, and no glue is needed for fixing, effectively improving environmental protection and prolonging service life, saving cost, and further improving practicality and applicability.

[0047] Embodiment 2

[0048] This embodiment is based on embodiment 1, and the engaging groove bottom 321 of the sink 200 is described in detail. Figures 1-4

[0049] One end of the groove bottom 4 is provided with a drain hole 41 penetrating through the groove bottom 4. Along the left-right direction x, the thickness of the groove bottom 4 gradually decreases from the side away from the drain hole 41 to the side close to the drain hole 41.

[0050] It should be noted that one end of the groove bottom 4 is provided with a drain hole 41 penetrating through the engaging groove bottom 321. The drain hole 41 can be connected to a drain pipe. Usually, the drain hole 41 is provided with internal threads or external threads. The drain pipe can be directly connected to the drain hole 41. Along the left-right direction x, the thickness of the groove bottom 4 gradually decreases from the side away from the drain hole 41 to the side close to the drain hole 41. When in use, the water flow quickly flows out of the drain pipe, which is not easy to cause water flow congestion, and improves the practicality.

[0051] The groove bottom 4 is also provided with a mounting groove 42. The mounting groove 42 is recessed downward from the groove bottom 4. Along the up-down direction z, the mounting groove 42 overlaps with the drain hole 41. The mounting groove 42 is embeddedly connected with the dirt-separating and water-draining basket 43.

[0052] ​It should be noted that along the up-down direction z, the installation groove 42 overlaps the drain hole 41, and along the left-right direction x, the top of the installation groove 42 is flush with the groove bottom 4, which does not affect the speed of water flowing out of the drain hole 41. The installation groove 42 is embeddedly connected with the dirt separation and water draining basket 43. The edge of the installation groove 42 is provided with a semicircular notch, which facilitates the taking of the dirt separation and water draining basket 43. The dirt separation and water draining basket 43 is provided with a plurality of hole positions, which can effectively filter out impurities in the used water, avoid the blockage of the drain pipe caused by too many impurities flowing into the drain pipe, and further improve the convenience of using the cabinet.

[0053] Embodiment 3

[0054] This embodiment is based on embodiment 2, and the sink 200 is described in detail with reference to Figures 1-4 The rear tank wall 52 is provided with a waterfall type water outlet 8 penetrating through the rear tank wall 52, and the waterfall type water outlet 8 is connected with a waterfall type water outlet device.

[0055] It should be noted that the waterfall type water outlet 8 includes a plurality of water outlets. Under the action of water pressure in the water pipe, water flows out of the holes to form a waterfall type water flow extending along the left-right direction x after the waterfall type water outlet device is opened, effectively improving the functionality of the sink 200.

[0056] It should be noted that the waterfall type water outlet device can be any existing device, and the present embodiment does not make specific limitations. The waterfall type water outlet device mainly utilizes the gravity, pressure of water flow and special design of the water outlet to make the water flow out in the form of a waterfall, thereby providing a wide, uniform and soft water flow. This design not only improves the convenience and comfort of water use, but also increases the aesthetics and practicality of the sink 200; the waterfall type water outlet device is usually connected to the water supply system of the sink 200. When the faucet is opened, the water flow is introduced into the device; in the device, the water flow is distributed to a plurality of water outlets, which can ensure that the water flow flows out in a uniform manner. When the water flow flows out of the water outlet, it will flow down along the wall surface or a special water outlet plate of the sink 200 due to the action of gravity, forming a waterfall type water flow; the waterfall type water outlet device usually collects the water flow to the bottom or a specific collection area of the sink 200, and then discharges it into the drainage system. In this process, the water flow can remove dirt and residues on the surface of the sink 200, playing a cleaning role.

[0057] The extension groove side 61 is provided with a mounting table 611 recessed towards the rear tank wall 52 on the side away from the waterfall type water outlet 8. The mounting table 611 is provided with a rotary faucet 9, a cup washer 10 and a switch 91, and the rotary faucet 9, the switch 91 and the cup washer 10 are detachably connected with the mounting table 611.

[0058] It should be noted that the installation table 611 recessed to the rear groove wall 52 on the side of the extension groove side 61 away from the waterfall water outlet 8 effectively saves the accommodation space required for installing the cabinet, further improves the practicability, and the rotating faucet 9, the cup washer 10 and the switch 91 can improve the functionality of the sink 200, effectively improving the user experience.

[0059] It should be noted that the rotating faucet 9 and the switch 91 are connected, and the switch 91 is also connected to the waterfall water outlet device, which can control the water outlet mode of the sink 200, effectively improving the functionality.

[0060] It should be noted that the cup washer 10 can be a press-type cup washer 10. The press-type cup washer 10 mainly utilizes the pressure of water and the special design of the water outlet to generate high-pressure water flow through the pressing action, so as to realize the cleaning of the cup. When in use, the cup to be cleaned is inverted and placed on the water outlet of the cup washer 10, and the pressing part of the cup washer 10 is pressed lightly with the hand. At this time, the piston in the cup washer 10 will be subjected to pressure, pushing the water flow through the water outlet. When the water flow is subjected to pressure, it will be sprayed from the water outlet in the form of high pressure, covering the inner wall of the entire cup. The high-pressure water flow can wash away the stains and residues on the inner wall of the cup, achieving the cleaning effect.

[0061] It should be noted that the cup washer 10 can be any existing one, for example, an ARROW high-pressure cup washer 10 model such as AE5990NC, which is suitable for sinks 200, milk tea, coffee commercial bar counters and other places, has the function of automatically washing cups, is convenient and fast, and is one of MEJUE high-pressure cup washers 10, HIGOLD press-type cup washers 10 and MOHAO high-pressure cup washers 10.
