[0017] Figure 2 is a sectional view of the cleaning sink in the embodiment of the utility model. DETAILED DESCRIPTION

[0018] The utility model will be described in further detail below in combination with the drawings.

[0019] The drainage device in the embodiment can be applied to various sink bodies, can be applied to ordinary sink bodies, and can be applied to integrated cleaning sinks capable of performing cleaning work, and when applied to cleaning sinks, the drainage and anti-clogging effects are more obvious.

[0020] As shown in Figure 1 and Figure 2 , the cleaning sink in the embodiment comprises a sink 1 and a drainage device arranged below the sink 1.

[0021] The sink 1 is a sink body structure having a water passage cavity, and the bottom of the sink 1 is provided with a drain port 11.

[0022] The drainage device comprises a drain pipe 2, a drain valve 3, and a jet flow channel 4.

[0023] The drain pipe 2 extends vertically as a whole, the drain pipe 2 is connected below the sink 1 by being butt-jointed with the water outlet, the drain valve 3 is arranged on the drain pipe 2, and the drain pipe 2 is controlled to drain and stop draining based on the opening and closing of the drain valve 3.

[0024] The jet channel is connected with the drain pipe 2, and the jet channel is connected with a water source. The jet channel can adopt a pipe body structure according to needs, and of course the jet channel can be integrally formed below the sink 1, and the structure form of the jet channel is determined according to the specific structure of the sink 1. When draining, the water source provides water with a certain water pressure for the jet channel, the pressure water is jetted into the drain pipe 2 through the jet channel, plays a siphon effect on the water in the drain pipe 2, and further strengthens the drainage speed and drainage pressure.

[0025] In addition, in order to better realize automatic opening and closing control of the jet flow channel 4, a switch valve 5 is arranged on the jet flow channel 4, the switch valve 5 can be electrically connected with other intelligent control modules on the sink 1, and then unified control work is performed, that is, when draining, the switch valve 5 is controlled to be opened, and water supply to the jet channel is realized. Specifically, the outlet of the switch valve 5 is connected with the inlet end of the jet flow channel 4, and the inlet of the switch valve 5 is connected with the water source through a water pipe.

[0026] The space below the sink 1 is usually limited, in order to ensure the length of the jet flow channel 4 and further ensure the jet water pressure of the jet water flow, the jet flow channel 4 needs to be reasonably arranged and arranged in the limited space below the sink 1. In order to facilitate the description, the jet flow channel 4 in the embodiment is divided into an upstream section 42 and a downstream section 41 along the water flow direction, wherein the upstream section 42 is away from the position connected with the drain pipe 2, and the downstream section 41 is close to the position connected with the drain pipe 2. The upstream section 42 of the jet flow channel 4 is arranged in a curved manner, and in the embodiment, the upstream section 42 of the jet flow channel 4 is in a U shape, so that the height space below the sink 1 can be fully utilized. The downstream section 41 of the jet flow channel 4 is inclined downward along the water flow direction, so that the jet pressure of the water flow from the jet flow channel into the drain pipe 2 can be further enhanced, and the siphon effect can be enhanced.
