Description

Technical Field

[0001] The utility model relates to the technical field of drainage devices, in particular to a floor drain core and a dual-purpose floor drain. Background Art

[0002] The laundry floor drain is a channel for washing machine drainage. When the washing machine is working, it will produce a lot of washing waste water, which is discharged into the floor drain through the drain pipe of the washing machine, and then enters the sewer system through the floor drain, ensuring that the waste water can be discharged smoothly and preventing water from accumulating on the ground or around the washing machine.

[0003] Nowadays, washing machine drainage and floor drainage are usually integrated in the market, which simplifies the drainage system and reduces the complexity of installation. Users no longer need to install drainage pipes for washing machines separately, thus saving installation time and cost. However, washing machines will produce a lot of foam during the washing process. If these foams cannot be quickly carried away by the water flow, they may cause the foam to overflow into the floor drain. After the foam overflows the ground, it will adhere to the ground, corners and other areas, forming stains that are difficult to remove. These stains not only affect the appearance, but are also difficult to completely remove with conventional cleaning methods. Users need to clean the overflowing foam additionally, which increases the difficulty and frequency of cleaning work. Utility Model Content

[0004] In view of the problems existing in the above-mentioned prior art, the utility model provides a floor drain core and a dual-purpose floor drain, which can effectively solve the problems existing in the above-mentioned prior art.

[0005] The technical solution of the utility model is:

[0006] According to one aspect of the utility model, a first water inlet is provided at the upper end of the floor drain core, and at least one second water inlet is provided on the side wall of the floor drain core. The second water inlet is flippably provided with a first sealing plate for preventing discharge from overflowing from the interior of the floor drain core. When the first sealing plate is flipped toward the interior of the floor drain core, the second water inlet opens.

[0007] Further, it comprises the floor drain core as claimed in claim 1, wherein a floor drain body is sleeved on the outside of the floor drain core, a water passage cavity is formed between the floor drain core and the floor drain body, and the second water inlet is used to communicate with the water passage cavity; when the second water inlet is opened, the floor drain core and the floor drain body form a second channel;

[0008] It also includes a connecting pipe, one end of which is connected to the first water inlet, and the other end of which is exposed outside the floor drain body, and the connecting pipe and the floor drain core form a first channel;

[0009] A connecting piece is fixedly arranged at the upper end of the floor drain core, and the connecting pipe is detachably fixedly arranged at the floor drain core through the connecting piece; a filter plate and a floor drain cover are fixedly arranged in sequence from bottom to top at the upper end of the floor drain body.

[0010] Furthermore, the number of the first sealing plates is at least two, and the two first sealing plates are both arranged on the inner side of the floor drain core.

[0011] Furthermore, the floor drain core is provided with a mounting hole, the upper end of the first sealing plate is hinged to the floor drain core through a pin shaft cooperating with the mounting hole, and the first sealing plate is fixed with a counterweight block for rotating the first sealing plate toward the second water inlet.

[0012] Furthermore, the floor drain core is provided with a make way groove, and when the first sealing plate and the floor drain core are closed, the lower end of the first sealing plate fits into the make way groove.

[0013] Furthermore, the first sealing plate is provided with at least one counterweight block extending toward the inside of the floor drain core.

[0014] Furthermore, a second sealing plate is hingedly provided at one end of the floor drain core exposed from the floor drain body; a baffle is provided extending downwardly at the hinged joint between the side wall of the floor drain core and the second sealing plate.

[0015] Furthermore, the baffle is provided with an arc-shaped groove toward the second sealing plate.

[0016] Furthermore, an arc-shaped protrusion is fixedly provided on the inner side of the floor drain core near the outlet, and the arc-shaped protrusion is in a triangular shape with a sharp corner facing upward.

[0017] By adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0018] Firstly, by flipping the first sealing plate, the discharge in the floor drain core is prevented from overflowing from the inside of the floor drain core; even if the laundry machine generates a large amount of foam during the washing process, the foam can be effectively prevented from overflowing onto the ground, thereby keeping the laundry area clean and dry. Moreover, the first channel and the second channel can be opened at the same time, so that the discharge from the laundry machine and the sewage on the ground can be discharged at the same time.

[0019] Secondly, during the installation of the floor drain, the baffle provides guidance and positioning, so that the floor drain core can be accurately placed in the predetermined position. In this way, even if there is a certain deviation in the installation position of the floor drain during the installation process, the baffle can also play a correction role to prevent the floor drain core from tilting or misalignment. Secondly, the existence of the baffle will not interfere with the normal opening and closing of the second sealing plate. If the floor drain is installed crookedly, the setting of the baffle can prevent the opening and closing of the second sealing plate from being interfered with.

[0020] Third, an arc-shaped protrusion is fixed on the inner side of the floor drain core near the outlet, and the arc-shaped protrusion is in the shape of a triangle with a sharp angle pointing upward. When sewage flows into the floor drain core, the arc-shaped protrusion can divert the sewage so that the sewage can be more evenly distributed around the outlet of the floor drain core, and the drainage efficiency is improved.
