[0002] The kitchen sink is one of the indispensable equipment in the kitchen, which undertakes the functions of cleaning tableware, washing food materials, and draining and garbage disposal, and provides many conveniences for users.

[0003] The existing kitchen sink mainly develops around the transverse direction of the sink, that is, the user mainly uses the space in the transverse direction (left and right direction) of the sink for operation, and the application of the longitudinal direction (front and back direction) of the sink is mainly to place the knife rack, chopping board and small cleaning articles at the rear position in the longitudinal direction of the sink, and install the faucet, so that the space in the longitudinal direction of the sink is not reasonably utilized, resulting in crowded operation space in the transverse direction of the sink. For example, when there is more than one dish for each meal, after processing one dish, the dish is placed at the edge of the sink in the transverse direction, which occupies the space in the transverse direction of the sink and reduces the operation space for processing the next dish, causing inconvenience to the user, or the dish is moved away from the sink, such as placed on the countertop, which may cause the dish to drip water onto the countertop, and requires a large space on the countertop. CONTENT OF THE UTILITY MODEL

[0004] The purpose of the embodiment of the application is to provide a sink to solve the technical problem that the sink in the prior art mainly uses the space in the transverse direction of the sink for operation, resulting in crowded operation space in the transverse direction of the sink.

[0005] To achieve the above purpose, the technical solution adopted by the application is to provide a sink, comprising:

[0011] Optionally, the first guide structure is a sliding groove or a guide rod.

[0012] Optionally, the inner walls of the trough body on both sides opposite to each other along the first horizontal direction are provided with a second guide structure, the length of the second guide structure extends along the second horizontal direction, and the opposite ends of the shelf along the first horizontal direction are respectively slidably engaged with the second guide structures on the opposite sides of the trough body along the first horizontal direction along the second horizontal direction.

[0013] Optionally, the second guide structure is a sliding groove or a guide rod.

[0014] Optionally, two layers of second guide structures are provided on inner walls on two opposite sides of the trough body along the first horizontal direction, and the two layers of second guide structures are spaced apart in the vertical direction.

[0015] Optionally, the shelf is arranged below the drain plate in a vertical direction.

[0016] Optionally, the first horizontal direction is the longitudinal direction of the trough body, and the second horizontal direction is the transverse direction of the trough body.

[0017] Optionally, when the size of the trough body along the first horizontal direction is equal to the size of the trough body along the second horizontal direction, the drain plate and the shelf can be stacked up and down in the trough body along the first horizontal direction or the second horizontal direction.

Water droplets from the dishes can flow into the sink body through the small holes in the drain plate, thereby preventing the countertop from being soiled. The size of the drain plate in the first horizontal direction is smaller than the size of the sink body in the first horizontal direction, and the size of the shelf in the second horizontal direction is smaller than the size of the sink body in the second horizontal direction. Therefore, the position of the drain plate in the first horizontal direction Y and the position of the shelf in the second horizontal direction can be adjusted by sliding the drain plate and the shelf, thereby avoiding interference with user operations.
