[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.
[0023] Please see Figure 1-7 In this embodiment of the utility model, a kitchen sink combining a single-sink and a double-sink configuration includes a sink body 1 and a dividing cutting board 2. The sink body 1 includes a sink main body 11, with edge ribs 12 on its sides and longitudinal ribs 17 in its middle. The dividing cutting board 2, when inserted into the longitudinal ribs 17, divides the sink main body 11 into a double-sink structure. A transverse rib 15, supporting the dividing cutting board 2, is also provided on the upper part of the sink main body 11. When the cutting board is inserted into a slot, it becomes a double-sink structure; when the cutting board is removed, it becomes a single-sink structure, allowing for easy switching. A front baffle 13 is provided at the front of the sink main body 11, a rear baffle 14 is provided at the rear of the sink main body 11, and a drainage hole 18 is provided at the bottom of the sink main body 11.
[0024] This application ensures that the sink size matches the cabinet size, with the sink supporting the weight of the cabinet. The marble countertop only needs to be aligned parallel to both ends of the sink to complete the installation; there is no need to worry about the marble countertop being too thin.
[0025] Make a 10mm raised fold at both ends of the sink. Cut a 2mm wide and 10mm deep slit along the edge of the marble. Fit the slit over the edge of the sink to complete the installation.
[0026] The entire sink includes 10mm folded edges at both ends, surface sealing welding, and polishing, making the entire sink surface a 10mm deep water basin, ensuring that the entire marble countertop will not leak.
[0027] The overall dimensions of the sink are identical to those of the cabinet. During installation, the sink rests on top of the cabinet, and the weight is borne by the cabinet side panels; the marble countertop does not bear the weight of the sink. Therefore, the marble countertop will not experience breakage or deformation due to the sink.
[0028] The installer doesn't need to cut holes in the sink; they can simply align the square marble with the edge of the sink to complete the installation.
[0029] When replacing the sink, adjust the cabinet feet down by 10mm so that the two ends of the sink are separated from the marble groove, then you can pull out the entire cabinet along with the sink for replacement.
[0030] The dividing cutting board 2 includes a cutting board body 21. The four sides of the cutting board body 21 are provided with concave structures that cooperate with the convex ribs. Rubber rings 22 are installed on both sides of the four sides of the cutting board body 21 located in the concave structures. Locking tongue components 23 are installed at two adjacent corners of the cutting board body 21. The longitudinal convex rib 17 has a notch 16 that cooperates with the locking tongue component 23.
[0031] The locking tongue assembly 23 includes a housing 231, with a locking tongue 233 movably mounted on the lower part of the housing 231. A spring 232 is provided between the locking tongue 233 and the housing 231. A lever 234 is rotatably mounted on the upper part of the housing 231, and the bottom of the lever 234 moves the locking tongue 233. A handle 237 is rotatably mounted on the top of the lever 234. The lever 234 and the housing 231 are connected by a first pin 235, and the lever 234 and the handle 237 are connected by a second pin 236. The specially designed cutting board has three grooves at both ends; the grooves on both sides are used to fix rubber rings, and the groove in the middle is used to insert the protruding rib of the sink. Two locking tongue assemblies 23 are installed on the upper part of the cutting board, and there are two handles on the top surface. Lifting the handles can loosen the locking tongue assembly 23. When the cutting board is in use, lifting the handles can be used to dry dishcloths.
[0032] The working principle of this utility model is as follows: After the dividing cutting board 2 is inserted into the longitudinal rib 17, it divides the main body of the sink 11 into a double-slot structure. The upper part of the main body of the sink 11 is also provided with a transverse rib 15 to support the dividing cutting board 2. When the cutting board is inserted into the slot, it is a double-slot structure. When the cutting board is pulled out, it becomes a single-slot structure, which can be switched at will. Two locking tongue components 23 are installed on the upper part of the cutting board, and there are two handles on the top surface. The locking tongue components 23 can be released by moving the handles. When the cutting board is in use, it can be used to dry dishcloths by moving the handles.
