Description

Technical Field

[0001] The utility model relates to the technical field of floor drains, in particular to a heating type filtering and anti-blocking floor drain. Background Art

[0002] As an important part of the drainage system in a house, the floor drain is an important interface between the drainage pipe system and the indoor floor. The floor drain can not only filter out debris, but also prevent bacteria, harmful gases and insects in the sewer pipe from returning to the room to affect air quality and environmental hygiene.

[0003] Common odor-proof floor drains mostly use water seal technology to use the water in the water trap to prevent odor. Currently, the floor drains used in food processing workshops or kitchens in residential buildings need to filter and discharge oily wastewater containing a large amount of grease residue. However, the grease in the water easily condenses and accumulates in the water trap in the water seal area, which in turn affects the drainage speed and water seal effect of the floor drain, and even blocks the drainage pipe, resulting in the inability to discharge kitchen sewage, which is easy to breed bacteria and produce odor. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a heating type filtering and anti-blocking floor drain, which can heat the water seal area at the bottom of the floor drain to prevent the condensation of oily wastewater, achieve the effect of multiple filtration and rapid drainage, and can effectively solve the technical problems of the existing water-sealed floor drain that easily condenses and blocks the pipe when discharging oily wastewater, resulting in slow drainage speed and poor water seal deodorization effect.

[0005] In order to achieve the above technical objectives, the utility model adopts the following technical solutions:

[0006] In one technical solution of the utility model, a heating type filtering and anti-blocking floor drain is provided, comprising a floor drain shell with a hollow interior, a dirt intercepting hanging basket and a filtering water seal are arranged inside the floor drain shell, and a heating device is arranged at the bottom of the floor drain shell;

[0007] The floor drain housing comprises a filter part and a water seal part integrally connected to the bottom of the filter part, a water inlet is provided on the top of the filter part, the water inlet is covered with a filter cover plate, a water seal pipe and a drain pipe are connected to the bottom opening of the water seal part, the water seal pipe is located inside the water seal part, the drain pipe is arranged below the floor drain housing, and the heating device is fitted and sleeved on the outside of the water seal part;

[0008] A first step is provided at the top opening of the filter part, and the sewage interception hanging basket abuts against the first step; a second step is provided at the connection position of the filter part and the water seal part, and the filter water seal component includes a filter sleeve and a water seal cover, the filter sleeve is clamped at the second step, the filter sleeve abuts against the bottom of the sewage interception hanging basket, the water seal cover is sealed at the top, opened at the bottom, and covers the outer side of the upper part of the drain pipe.

[0009] By adopting the above technical scheme, after the sewage passes through the filter cover to filter out the larger debris and garbage, it flows into the sewage interception basket, and after being filtered by the sewage interception basket, it flows into the filter part, and then further filtered by the filter sleeve and flows into the water seal part below. After multiple layers of filtration, the debris in the sewage can be effectively removed, and the drainage speed can be improved. When the water level of the water seal part exceeds the water seal pipe, the sewage is discharged into the external sewage pipe through the water seal pipe and the drain pipe. After the drainage is completed, part of the sewage will remain between the water seal cover and the drain pipe to form a water seal area for water seal and odor prevention, so as to prevent the odor in the drain pipe from flowing back into the room. This scheme can heat the water seal part by arranging a heating device on the outside of the water seal part, thereby improving the fluidity of the grease-containing sewage and preventing the grease contained in the sewage from being deposited and blocked at the bottom of the water seal part, thereby improving the drainage speed and ensuring a good water seal effect.

[0010] Furthermore, a hanging portion is extended in all directions from the upper open end of the sewage interception hanging basket, the hanging portion is hung at the first step, a filter cover plate is pressed above the hanging portion, and the side walls of the sewage interception hanging basket form a water-permeable portion that is thick at the top and thin at the bottom. The bottom of the sewage interception hanging basket is watertight and forms a sealing portion. The sewage is filtered through the water-permeable portion and then enters the filter portion below.

[0011] Furthermore, the filter sleeve and the water seal cover are fixedly connected by a plurality of spaced connecting rods, which can ensure the structural strength of the filter water seal. At the same time, after being filtered by the filter sleeve, the sewage flows into the water seal part through the gaps between the connecting rods, thereby ensuring smooth drainage.

[0012] Furthermore, the filter sleeve and the water seal cover are both cylindrical and coaxially distributed, the outer diameter of the filter sleeve is larger than the outer diameter of the water seal cover, and the sealing part covers the upper opening of the filter sleeve, so as to ensure that the sewage passes through the water-permeable part of the sewage interception hanging basket and enters the filter part after being filtered, and then after being filtered by the filter sleeve, flows into the water seal part through the gap between the connecting rods, and finally is discharged through the drain pipe.

[0013] Furthermore, a plurality of first water filtering holes are provided on the filter cover plate, a plurality of second water filtering holes are provided on the water permeable portion, and a plurality of third water filtering holes are provided on the filter sleeve.

[0014] Furthermore, the distance between the top port of the drain pipe and the bottom side surface of the water seal portion is not less than 50 mm, meeting the national standard water seal height and ensuring a better water seal deodorization effect.

[0015] Furthermore, the side wall of the water seal part is cylindrical, and the distance between the inner diameter of the water seal part and the outer diameter of the water seal cover is equal to the distance between the inner diameter of the water seal cover and the outer diameter of the drain pipe, which can ensure a faster discharge speed of the water flow and a better deodorizing effect of the water seal area.

[0016] Furthermore, the bottom end of the water seal cover is located between the bottom inner side surface of the water seal portion and the top port of the drain pipe, which is conducive to forming an effective water seal area and ensuring a good drainage speed.

[0017] Furthermore, the heating device includes a casing and a hollow layer inside the casing, the inner side of the casing is in contact with the outer surface of the water seal, and heating wires are evenly distributed in the hollow layer. The heating wires are electrically connected to an external power source, and the heating wires in the hollow layer are heated by powering on, and the water seal is heated by heat conduction, thereby ensuring that the sewage containing grease will not solidify and accumulate at the bottom of the water seal, causing blockage and affecting drainage.

[0018] Furthermore, the bottom of the casing is open and is sleeved on the outside of the drain pipe, and the lower part of the casing abuts against a limiting ring, which is sleeved on the outside of the drain pipe and forms a fixed connection. The installation position of the heating device is limited by the fixed connection between the limiting ring and the drain pipe, ensuring that the casing fits on the outer surface of the water seal part, thereby ensuring a good heat conduction effect.

[0019] The utility model has the following beneficial effects:

[0020] The heated filtering and anti-blocking floor drain provided by the utility model is easy to install, has good filtering effect, fast drainage speed, low manufacturing cost, and is suitable for mass production and manufacturing. It can not only filter out large debris in sewage, but also heat oily sewage to prevent grease residues in the sewage from condensing and accumulating at the bottom of the water seal part, thereby affecting the drainage speed and water seal effect of the floor drain.
