Description

A siphon deep water seal deodorant floor drain

Technical field

The utility model relates to a siphon type deep water seal and odor-resistant floor drain, which belongs to the technical field of floor drain.

Background technique

The floor drain is an important interface between the sewer system and the indoor floor. As an important part of the residential drainage system, its performance directly affects the quality of the indoor air, and is even important for the healthy living quality of people in the house.

At present, there are mainly kinds of building drainage floor drains such as ordinary water-sealed type, mechanical closed type and floating body valve odor-removing type. Although these kinds of drainage floor drains have their own advantages, they also have a problem at the same time, that is, the drainage speed is slow and far from the national standard. For example, when using a large-flow shower, there is often a phenomenon that water cannot be discharged in time, and it cannot meet the drainage requirements of people's daily life. If a large amount of water is leaked when the faucet or water pipe bursts, even if the floor drain is not blocked, Poor drainage of the floor drain leads to excessive water accumulation in the home, causing irreparable damage to itself and the underlying building. Some patents, such as the patents 200910263667.X and 201120201463.6, also propose to use siphon to increase the flow, but the structure is unreasonable, the actual effect of siphoning is not achieved, and the drainage speed is still slow. In addition, the ordinary water-sealed floor drain, the water seal height can not reach the national standard, and the water seal is easy to dry, the deodorant effect is not ideal.

Utility model content

The utility model overcomes the deficiencies of the prior art, completely solves the problem that the existing floor draining and discharging speed is slow, and provides a siphon type large-flow water-sealed and odor-resistant floor drain which has a simple structure and can greatly improve the drainage speed.

In order to solve the above technical problems, the technical scheme adopted by the utility model is: a siphon type deep water seal deodorant floor drain, including a floor drain main body, a water seal cover, an outer frame and an inlet water dice, and the floor drain main body is an upper open shell, a floor drain A tubular drainage chamber is arranged in the main body, the water seal cover is open downward, and is buckled above the drainage chamber, and a water seal is formed between the drain body and the drain chamber, the outer frame is disposed above the floor drain body, and the water inlet dice are mounted on the outer frame. The utility model further comprises a siphon member occupying a space of a central portion of the upper portion of the drainage chamber, wherein one end of the siphon member is connected to the inner top portion of the water seal cover, and the other end of the siphon member extends into the drainage chamber, and a circle is arranged on the inner wall of the drainage chamber. The annular choke is raised, and the annular choke is located below the siphon.

The wicking member is a solid cylinder, or a hollow cylinder, or a hollow tubular member, or a cone, or a pyramid, or a frustum, or a structure in which a lower end of the cylinder is connected to a hemisphere, or a cylinder. The lower end is connected to the structure of the curved plate, or the structure in which the lower end of the cylinder is connected to the sphere.

One end of the siphon member is directly fixed to the inner top of the water seal cover, or is connected to the inner top portion of the water seal cover through a plurality of ribs.

The water seal cover is further provided with a ring of water-sealing cover tweezers to form a double-layered tweezers.

The upper portion of the water seal covers the protrusion provided on the inner wall of the floor drain body.

The upper portion of the water seal cover is engaged with the inner wall of the floor drain body by a buckle.

A groove for inserting the drain pipe is formed between the bottom of the drain chamber and the floor drain body.

Compared with the prior art, the utility model has the following beneficial effects:

1. The siphon effect is fast and the flow rate is large. In the utility model, since the siphon member protrudes into the drainage cavity and cooperates with the annular choke boss, the water flow rapidly fills the upper part of the drainage cavity, and the siphon effect can be quickly generated. The water flow is accelerated and the flow rate is increased. Compared with the arrangement of the siphon and the annular choke in the drain chamber, the flow rate is greatly improved. In actual use, it can meet people's daily life or emergency drainage requirements.

2, anti-drying is good, the height of the water seal of the utility model reaches 50mm, in line with national standards, far exceeding the water seal height generally leaking on the market, greatly extending the water seal retention time.

3, the deodorant and insect-repellent effect is good, the utility model adopts high water seal and deodorization, and has the design of prolonging the drying time, and the deodorant and insect proof effect is good and reliable.

4, good impurity removal, the water dice in the utility model and the water seal cover tweezers, forming a double layer of tweezers, can effectively filter and collect slightly larger impurities such as hair in the sewage, and clean up after collection It is easy to ensure that the utility model and the sewer are unobstructed.

5, self-cleaning function is good, anti-blocking ability is strong, because the utility model is designed to use the siphon principle, so that it produces a large suction when draining, can effectively remove impurities mixed in the sewage, deposits, effectively prevent the floor drain blockage, has very Strong self-cleaning ability.
