Description

Technical Field

[0001] The utility model belongs to the technical field of drainage floor drains and relates to an ultra-thin floor drain for same-layer drainage. Background Art

[0002] The floor drain is an important interface connecting the drainage pipe system and the indoor floor. It is an important component of the drainage system in a house. Its performance directly affects the quality of indoor air and is very important for odor control in the bathroom.

[0003] The types of floor drains in the prior art mainly include two types: water-free floor drains and self-contained water-sealed floor drains. Among them, water-free floor drains require a separate water seal. For the same-floor drainage area with no drop plate or slight drop plate, it is necessary to consider the setting of a floor drain trap at the riser. Generally, a drainage collector is used, which is costly and occupies a large space. Self-contained water-sealed floor drains are currently relatively thick, and the slope of the floor drain drainage pipe requires a relatively large installation space. A relatively large drop plate height or building surface layer needs to be set to meet the installation requirements of the floor drain. Moreover, for areas where the floor drain is not used frequently, the water seal is easy to dry up, causing odor to overflow into the room.

[0004] For the same-layer drainage area without a drop plate or a slightly drop plate, the above two types of floor drain structures are obviously not applicable. Therefore, an ultra-thin floor drain that can achieve same-layer drainage without a drop plate or a slightly drop plate is urgently needed in this field. Utility Model Content

[0005] In view of the problems existing in the prior art, the utility model provides an ultra-thin floor drain with same-layer drainage. Through effective structural design, water sealing and drainage are integrated into one, thereby realizing an ultra-thin design of the floor drain.

[0006] The utility model is realized as follows: an ultra-thin floor drain with same-floor drainage comprises a shell; a water inlet chamber, a water seal chamber, a water collection chamber, and a drainage chamber are sequentially provided inside the shell; a first water through hole is provided at the top of the water inlet chamber, and a second water through hole is provided at the bottom; the water seal chamber is communicated with the second water through hole, a third water through hole is provided at the top of the water seal chamber; the water collection chamber is communicated with the third water through hole, a fourth water through hole is provided at the bottom of the water collection chamber; the drainage chamber is communicated with the fourth water through hole, and a drainage pipe communicating with the outside is provided at the bottom of the drainage chamber;

[0007] The horizontal plane height of the second water hole is lower than that of the third water hole; the horizontal plane height of the third water hole is higher than that of the fourth water hole;

[0008] An automatically closing anti-odor plate is provided at the fourth water hole in the drainage cavity.

[0009] As one of the preferred embodiments, the shell has a square cross-section.

[0010] As one of the preferred embodiments, the cross section of the shell is circular.

[0011] As one of the preferred embodiments, the automatically closing anti-odor plate is hingedly connected to the drainage chamber.

[0012] The working mode of the utility model is as follows:

[0013] This floor drain is pre-buried in the building surface. Water from the ground flows into the water inlet chamber through the first water hole, while accumulated water flows into the water seal chamber through the second water hole. When the water level in the two chambers reaches the third water hole, it overflows into the water collection chamber through the third water hole. When the water in the water collection chamber reaches a certain height, it pushes the automatic closing anti-odor plate to flow into the drainage chamber through the fourth water hole, and finally out through the drain pipe. When there is no water in the water collection chamber or the water volume is low, the automatic closing anti-odor plate remains closed, effectively blocking the odor in the drainage riser.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] The utility model realizes the water seal by providing a water seal cavity and water holes of different heights, eliminating the need for a separate water seal structure and water trap. The floor drain can achieve the same-level drainage without lowering the floor, eliminating the need for a separate floor drain water seal, and truly realizing the principle of self-drainage in the home.

[0021] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0022] The structure of the present utility model is described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 and Figure 4As shown, a same-floor drainage ultra-thin floor drain includes a cylindrical shell 1 with a height of 60 mm. The shell 1 is provided with a water inlet chamber 2, a water seal chamber 3, a water collection chamber 4, and a drainage chamber 5 in sequence. The water inlet chamber 2 is provided with a first water hole 11 at the top and a second water hole 21 at the bottom. The water seal chamber 3 is connected to the second water hole 21, and a third water hole 31 is provided at the top of the water seal chamber 3. The third water hole 31 is 50 mm above the bottom surface. The water collection chamber 4 is connected to the third water hole 31, and a fourth water hole 41 is provided at the bottom of the water collection chamber 4. The drainage chamber 5 is connected to the fourth water hole 41, and a drainage pipe 6 connected to the outside is provided at the bottom of the drainage chamber 5.

[0024] The horizontal height of the second water hole 21 is lower than that of the third water hole 31 ; the horizontal height of the third water hole 31 is higher than that of the fourth water hole 41 ;

[0025] An automatically closing anti-odor plate 51 is provided at the fourth water hole 41 in the drainage chamber 5 .

[0026] Preferably, further, the automatically closing anti-odor plate 51 is hingedly connected to the drainage chamber 5 .

[0027] It should be noted that the housing 1 may also be designed to be square.

[0028] The working principle of this utility model:

[0029] This floor drain is primarily pre-buried in the building's surface layer. Groundwater flows through the first water hole 11 into the water inlet chamber 2, then through the second water hole 21 into the water seal chamber 3. When the water level in the water seal chamber 3 reaches the lower edge of the third water hole 31, the accumulated water flows into the water collection chamber 4, achieving the required 50mm water seal height. When the drainage in the water collection chamber 4 reaches a certain height, the automatically closing odor-proof plate 51 is pushed, allowing the drainage to flow into the drainage chamber 5 and out. When the water in the water collection chamber 4 is empty or low in water, the automatically closing odor-proof plate 51 remains closed, effectively blocking odors from the drainage riser.

[0030] The same-floor drainage ultra-thin floor drain provided in this embodiment not only meets the water seal height requirement of 50mm, but also minimizes the installation space (minimum installation space 60mm). It can be installed in the building surface layer without lowering the board.

[0031] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent will not depart from the scope of the technical solution of the present invention.
