Description
Technical Field
[0001] The utility model relates to the technical field of kitchen and bathroom, in particular to a rear telescopic drainer. Background Art
[0002] For the installation of the drainer, it is mostly directly installed directly below the sink. The space directly below the sink is divided in the middle, making it difficult to form a complete storage space under the sink. For example, it is difficult to design and build storage compartments, and it is difficult to store larger items. Moreover, due to the uneven arrangement of the drain pipes, it is also inconvenient to take and place items. Therefore, the utility model provides a rear-mounted drainer that can be telescopically adjusted in size to solve the above technical problems. Summary of the Utility Model
[0003] In order to solve the above technical problems, the utility model proposes a rear-mounted and telescopically adjustable drainer structure.
[0004] A rear telescopic drainer includes a drainer main body, an adjusting pipe, and a drainage component. Specifically,
[0005] The drainer main body includes a drain cup body, and a side drain joint is provided at the peripheral part of the bottom end of the drain cup body.
[0006] One end of the adjusting pipe is an inlet joint, and the other end is an outlet joint. The inlet joint and the side drain joint of the drain cup body are inserted into each other, and a telescopic limit member is provided at the insertion position for relatively fixing the inlet joint and the side drain joint. The distance between the outlet joint and the drain cup body is adjusted by loosening the telescopic limit member, so that the outlet joint can be adjusted to be close to or fit against the wall surface under the sink, minimizing the occupation of the middle space under the sink as much as possible.
[0007] One end of the drainage component is a water passing joint, and the other end is a drainage end. The water passing joint and the outlet joint of the adjusting pipe are inserted into each other and relatively fixed.
[0008] For the drainer provided by the utility model, the drainer main body adopts a side drainage structure. At the same time, a telescopic adjustable structure is combined with the adjusting pipe. During installation, the outlet of the drainer main body can be adjusted to be close to or fit against the wall surface under the sink, and then the drainage component is connected, so as to minimize the occupation of the middle space under the sink as much as possible. For the middle space and the front space under the sink, on the one hand, it is convenient to design and arrange a storage rack or a storage compartment under the sink. On the other hand, larger items can also be stored under the sink. At the same time, it is not easy for the items to interfere with the drain pipes when taking and placing.
[0009] Preferably, among the water inlet joint and the water outlet joint, the outer tube is sleeved on the outside, and the inner tube is sleeved on the inside. The telescopic limiting member includes an annular locking cover and a limiting sealing ring. The annular locking cover and the limiting sealing ring are sequentially sleeved on the outside of the inner tube. One end of the annular locking cover away from the end opening of the inner tube is a reduced opening, and the cross section of the limiting sealing ring is triangular, and the tip faces the end opening of the inner tube. The inner circle of the end opening of the outer tube is chamfered to form an inclined surface. The inner tube is inserted into the outer tube, and the annular locking cover and the end of the outer tube are tightened by threads. The limiting sealing ring enters the gap between the inclined surface and the outer wall of the inner tube through the extrusion of the annular locking cover, and tightly adheres to the inclined surface and the outer wall of the inner tube through extrusion deformation, so as to form a locking effect and a sealing effect.
[0010] Preferably, to prevent the inner tube from being completely pulled out of the outer tube when adjusting the length, a convex ring is provided on the circumference of the part of the inner tube inserted into the outer tube. The outer diameter of the convex ring is larger than the inner diameter of the limiting sealing ring. After the limiting sealing ring is elastically expanded, it passes through the convex ring and is sleeved on the inner tube. When the inner tube is pulled out, the convex ring is blocked by the limiting sealing ring, and the limiting sealing ring is blocked by the inner wall of the reduced opening of the annular locking cover.
[0011] Preferably, the side drain joint is an inner tube, and the convex ring is provided on the circumference of the end of the side drain joint.
[0012] Preferably, an upward water inlet branch pipe is provided in the middle of the adjusting pipe. The water inlet branch pipe is connected to an overflow cover through a connecting pipe and can be installed at the overflow hole of the sink to prevent the water in the sink from entering the storage space at the bottom of the sink through the overflow hole.
[0013] Preferably, the drainage assembly includes a connecting pipe and a drainage pipe. One end of the connecting pipe is the water passing joint, and the other end is the lower drainage joint. The top end of the drainage pipe is relatively fixedly docked with the lower drainage joint, and the bottom end is the drainage end.
[0014] Preferably, there is also a telescopic limiting member between the water passing joint and the water outlet joint, so that the distance from the drainage pipe to the main body of the drainer can also be adjusted, and the use of the entire drainer is more flexible.
[0015] Preferably, the connecting pipe is in a T shape and has two water passing joints, which are respectively docked with a group of the main body of the drainer and the adjusting pipe, and can be applied to the scenario with two sinks.
[0016] Preferably, to prevent water backflow or water impact between the opposite two water passing joints, a one-way valve is provided in the connecting pipe or the adjusting pipe, and a partition plate is provided at the water inlet of the lower drainage joint. The partition plate separates the communication space between the two water passing joints.
[0017] Preferably, in order to reduce the impact on the drainage speed, the partition plate is inclined with respect to the axis between the two water connection joints, or the partition plate is an arc-shaped plate or an S-shaped plate.
[0018] As can be seen from the above description of the present invention, the present invention has the following beneficial effects:
[0019] For the drainer provided by the present invention, the drainer body adopts a side drainage structure. At the same time, a telescopic and adjustable structure is combined with the adjusting pipe. During installation, the water outlet of the drainer body can be adjusted so that it can be close to or fit the wall surface under the sink, and then the drainage assembly is connected, thereby minimizing the occupation of the middle space under the sink as much as possible. For the middle space and the front space under the sink, on the one hand, it is convenient to design and arrange a storage rack or storage partition under the sink. On the other hand, larger-sized objects can also be stored under the sink, and at the same time, it is not easy for the taking and placing of objects to interfere with the drain pipe;
[0020] The telescopic limiting member includes an annular locking cover and a limiting sealing ring, which has a simple structure and not only has a locking effect but also a sealing effect;
[0021] By providing a convex ring, it is possible to prevent the inlet joint and the outlet joint from detaching when adjusting the length;
[0022] The connecting pipe is in a T shape and has two water connection joints, which can be applied to the scenario with two sinks;
[0023] A one-way valve is provided in the connecting pipe or the adjusting pipe, and a partition is provided at the water inlet of the lower drain joint to prevent water backflow or water counterflow between the opposite water connection joints;

One end of the annular locking cover 4 with an open end away from the inner tube is a reduced opening 41, and the cross-section of the limiting sealing ring 5 is triangular, and the tip faces the open end of the inner tube. The inner ring of the end opening of the outer tube is chamfered to form an inclined surface. The inner tube is inserted into the outer tube, and the annular locking cover 4 and the end of the outer tube are screwed tightly through threads. The limiting sealing ring 5 enters the gap between the inclined surface and the outer wall of the inner tube through the extrusion of the annular locking cover 4, and is tightly attached to the inclined surface and the outer wall of the inner tube through extrusion deformation, so as to form a locking effect and a sealing effect.
