Description

Technical Field

[0001] The utility model relates to the field of building drainage floor drains, in particular to a same-floor drainage floor drain with a water seal. Background Art

[0002] The drop-down, same-floor drainage system is installed within the building's caisson. Caisson structures often utilize either a full or partial drop-down design. The bathroom floor is lower than the living room floor, and drainage laterals are located on this floor. The appliance drain pipes do not penetrate the floor. A floor drain is a drainage device that connects the floor to the drainage system, removing surface water, water stains, solid matter, hair, and easily sedimented materials. A water seal is a water retention structure within the floor drain that prevents the escape of harmful gases and other pollutants. In this drop-down, same-floor drainage system, the caisson drop height is typically 350mm. After the lower screed and waterproofing are completed, the effective caisson dimension is less than 300mm. Horizontal branches are installed with a slope requirement, and floor drains are typically installed at the beginning of the drainage lateral branch. Adding a 90-degree elbow to the outlet of a conventional lower drainage floor drain results in an excessively high installation height. During installation, the upper water inlet protrudes beyond the finished decorative surface, preventing drainage.

[0003] When using a side drain with a water seal as a dry area floor drain, the water seal often fails due to evaporation due to lack of water replenishment, causing odor to return to the bathroom. If a water replenishment tee is added, the drainage branch pipe is installed too high, exceeding the finished surface of the caisson, making it impossible to drain water. Utility Model Content

[0004] In order to solve the problem that the standard floor drain with water seal in the prior art cannot be used in same-floor drainage due to structural size issues, the utility model provides a same-floor drainage floor drain with water seal.

[0005] The technical solution of the present utility model is achieved as follows:

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1: Figure 1 and Figure 2 The shown type of same-layer drainage floor drain with a water seal includes: a water seal container 1, an adjustment sleeve 2, a grate seat 3 and a grate 4. The water seal container 1 is configured as a circular or flat cavity, and a water outlet 5 is provided on the side of the cavity, a cylindrical boss 6 is provided on the top, a partition 7 is provided inside and the top end of the partition is connected to the top of the water outlet, the partition 7 divides the cavity into a water inlet cavity 11 and a water seal container cavity 12 forming a U-shaped flow channel, and an upwardly extending baffle 8 is provided on the side where the inner wall of the water outlet intersects with the water seal container cavity, the lower end surface of the partition 7 and the upper end surface of the baffle 8 form a water seal, and the bottom end of the partition forms a water channel with the water seal container cavity and the baffle; the adjustment sleeve 2 is connected to the cylindrical boss 6, the grate seat is sleeved on the adjustment sleeve, and the grate cover is on the grate seat.

[0027] like Figure 1 and Figure 3As shown, the adjustment sleeve 2 comprises an inlet sleeve 21 and an adjustment sleeve 22. The inlet sleeve has a larger diameter than the adjustment sleeve, and a curved bevel transition is formed between the upper inlet sleeve and the lower adjustment sleeve. The adjustment sleeve 2 has an externally threaded exterior, while the cylindrical boss 6 is internally threaded. The external and internal threads connect the adjustment sleeve and cylindrical boss. This connection between the adjustment sleeve and cylindrical boss stabilizes the grating when stepped on, preventing the adjustment sleeve from sinking.

[0028] like Figure 1 As shown, the cross section of the cavity is set to be oval or rectangular with rounded corners, and the water outlet 5 is set on one side of the cavity, so that the water flow is smoother. Figure 2 As shown, the bottom end of the partition 6 is a circular structure, and the top end of the baffle is set to a circular structure, which can reduce the dirt in the water seal container hanging on the partition and baffle to affect drainage.

[0029] The water seal height of 50 mm in Example 1 meets operational requirements, and the water seal depth can be increased to 80 mm as needed. The height of the adjustment sleeve can be adjusted between the adjustment sleeve and the cylindrical boss, and the height of the adjustment sleeve can also be directly adjusted to meet the on-site installation depth. While maintaining the water seal height, the water seal container cavity can be lowered to reduce the height of the water outlet, thereby reducing the space required and improving adaptability.

[0030] like Figure 2 As shown, the top of the partition 7 is set to be an arc shape, which transitions from the partition to the inner top of the cavity and extends to the water outlet 5, and is tangent to or intersects with the water outlet. The water seal depth H between the lower end face of the partition 7 and the upper end face of the baffle 8 makes it easy to achieve that the cross-sectional area between the top of the partition and the baffle is larger than the cross-sectional area of ​​the water outlet. The partition 7 is set to an arc structure to guide the water flow. No drainage dead angle will be formed at the partition 7 and the water outlet, making drainage smoother and the self-cleaning ability better.

[0031] Example 2: Figure 4 The illustrated water-sealed same-floor drainage floor drain, based on Example 1, features a side water inlet section 9 on one narrow side of the cavity. The horizontal axis of the side water inlet section is higher than the horizontal axis of the water outlet, and the bottom of the side water inlet section is higher than the bottom of the water outlet. The height difference between the side water inlet section and the water outlet can be greater than 10 mm and less than or equal to 70 mm. The height difference between the side water inlet section and the water outlet can be adjusted to meet different requirements while ensuring water sealing performance.

[0032] Example 3: Figure 5 The illustrated water-sealed same-floor drainage floor drain, based on Example 2, features a side water inlet section 9 on one wide side of the cavity. The horizontal axis of the side water inlet section is higher than the horizontal axis of the water outlet, and the bottom of the side water inlet section is higher than the bottom of the water outlet. The height difference between the side water inlet section and the water outlet can be greater than 10 mm and less than or equal to 70 mm. The height difference between the side water inlet section and the water outlet can be adjusted to meet different requirements while ensuring water sealing performance.

[0033] Example 4: Figure 6 The illustrated water-sealed same-floor drainage floor drain, based on Example 2, features side inlet sections 9 on both wide sides of the cavity. The horizontal axis of these sections is higher than the horizontal axis of the outlet, and the bottom of these sections is higher than the bottom of the outlet. The height difference between the side inlet section and the outlet can be greater than 10 mm and less than or equal to 70 mm. This height difference between the side inlet section and the outlet can be adjusted to meet various requirements while ensuring water sealing performance.

[0034] Example 5: Figure 7 The illustrated water-sealed same-floor drainage floor drain, based on Example 2, features a side water inlet section 9 on each side of the cavity. The horizontal axis of the water inlet section is higher than the horizontal axis of the water outlet, and the bottom of the water inlet section is higher than the bottom of the water outlet. The height difference between the side water inlet section and the water outlet can be greater than 10 mm and less than or equal to 70 mm to meet different requirements while ensuring water sealing performance.

[0035] The above-mentioned embodiments 1 to 5 can be processed and produced using the same mold, which improves the demand for the use of water-sealed same-layer drainage floor drains and reduces processing costs.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
