Description

Technical Field

[0001] The invention relates to the technical field of ceramic basins, and in particular to a ceramic basin assembly with rear drainage. Background Art

[0002] Most of the ceramic basins used in the industry now have round holes in the bottom of the basin to install drainers. The drain pipes connected to the drainers are either straight or tilted, which takes up a lot of space in the cabinet, and the appearance of the basin is not beautiful enough. The flip-top drainer is easy to "get stuck" when the lid is flipped to drain water, and most of them do not have a basket filtering function, and cannot filter hair and other debris, which easily causes the sewer pipe to be blocked.

[0003] Nowadays, most ceramic basins are equipped with overflow holes, overflow channels, overflow rings, etc. For basins made of ceramic materials, overflow holes are usually left when the basin is made, which affects the aesthetics of the basin and is prone to sanitary dead corners and blockage of the overflow channel.

[0004] In addition, the water storage height of the existing water basin is fixed and cannot be adjusted. During use, the water basin without overflow holes may overflow and be unable to drain due to various factors, causing trouble for users in daily use.

[0035] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0036] See also Figures 1 to 3 The present invention provides a ceramic basin assembly with rear drainage, including a basin body 100 and a drain 200;

[0037] The basin body 100 includes a table top 101 and a water reservoir 102. The table top 101 is provided with a mounting hole 103 for mounting the drain 200. The side wall of the water reservoir 102 is provided with a drain port 104.

[0038] The drain 200 is communicated with the drain port 104, and comprises a main pipe 1, a presser assembly 2 connected to the main pipe 1, and an overflow drain assembly 3 sleeved in the main pipe 1; the overflow drain assembly 3 comprises a spring member 31 connected to the presser assembly 2, a water sealing member 32 driven by the spring member 31, and an overflow pipe 33 arranged outside the spring member 31;

[0039] The diameter of the overflow pipe 33 is smaller than that of the main pipe 1 . The overflow pipe 33 divides the inner channel of the main pipe 1 into a sewer channel 4 and an overflow channel 5 . The water sealing member 32 can be driven to open or close the sewer channel 4 . The overflow channel 5 is connected to the drain outlet 104 .

[0040] Specifically, the drain 200 is installed in the installation hole 103, and the user can drain water without touching the dirty water. The drain port 104 is located on the side wall of the water reservoir 102, and the drain 200 is placed behind the ceramic basin, thereby releasing the storage space of the cabinet; and the drain port 104 is hidden, so that the basin body 100 has good aesthetics. The basin body 100 has no dead corners, and the drain port 104 and the basin body 100 are easy to clean, which solves the problem that dirt such as mud and sand are easily deposited at the connection between the existing drain 200 and the basin body 100, and reduces the breeding of bacteria and the generation of odor.

[0041] The drain 200 is arranged in cooperation with the basin body 100. The drain 200 includes a main pipe 1 for drainage. The presser assembly 2 is installed on the main pipe 1. The presser assembly 2 is connected to the overflow drain assembly 3. Pressing the movable part of the presser assembly 2 can drive the overflow drain assembly 3 to move, specifically by driving the spring member 31 to move, and drive the water sealing member 32 to move, so as to open or close the drain channel 4. In order to integrate the overflow function into the drain 200 and solve the problem that the basin body 100 in the prior art still needs to be provided with an overflow pipe, the overflow pipe 33 is sleeved in the main pipe 1, and the overflow pipe 33 can separate the channel of the main pipe 1 into a drain channel 4 and an overflow channel 5. When the water sealing member 32 blocks the drain channel 4, the water in the basin body 100 enters the overflow pipe 33 through the drain port 104, and the water storage height is controlled by the overflow height of the overflow pipe 33. When the water level in the water reservoir 102 is higher than the overflow height of the overflow pipe 33, the water is discharged from the overflow channel 5. When the water sealing member 32 is opened, the drain channel 4 is opened, so that the water is drained smoothly. When the drain 200 needs to be thoroughly cleaned, the movable part of the presser assembly 2 and the overflow drain assembly 3 can be taken out as a whole for cleaning, and the cleaning effect is good.

[0042] See also Figure 2 In order to further save the storage space in the cabinet and facilitate installation, the drain port 104 is on the rear wall of the basin 100, and the inner bottom surface of the water reservoir 102 is inclined toward the drain port 104, so that the sewage can be fully discharged, the water reservoir 102 and the drain port 104 are kept dry, and the growth of bacteria is reduced. In order to facilitate the installation of the drain 200, a fixing rib 105 and a mounting platform 106 are provided on the rear outer wall of the basin 100, and a transverse assembly hole 107 is provided on the fixing rib 105.

Among them, the first water inlet pipe 331 is arranged on the side wall of the overflow pipe 33, and the overflow pipe 33 is integrally formed with the main pipeline 1, or the first water inlet pipe 331 is sealed and connected with the insertion port 11. The water sealing member 32 abuts against the inner pipe wall of the overflow pipe 33, dividing the overflow pipe 33 into an upper half and a lower half. The lower half of the overflow pipe 33 is a water discharge channel 4, and the overflow channel 5 includes the upper half of the overflow pipe 33 and the interlayer between the overflow pipe 33 and the main pipeline 1. The water discharger 200 of this structure has a simple structure and is easy to install.

Specifically, by rotating the direction of the adjusting pipe 333, the clamp block 337 slides in the clamp ring 335 and slides into the adjusting guide groove 336 at a corresponding position, and the water storage height is determined by the length of the adjusting guide groove 336. Wherein, the length of the adjusting guide groove 336 is determined according to the existing common basin depth, thereby improving the versatility of the drain 200.

[0047] Furthermore, in order to adapt to the requirements of different installation lengths of the water drain 200, a mounting tube 6 is also sleeved in the main pipe 1, and the presser assembly 2 is connected to the mounting tube 6; the mounting tube 6 can be extended and retracted relative to the main pipe 1, and the mounting tube 6 and the main pipe 1 are connected by a locking assembly 7.
