The conventional definition of a floor drain is a drainage fixture that is connected to the ground with a drainage system. Of course, since the upper part of the floor drain is developed, the washing unit provided above the ground can also drain through the floor drain to the drainage system. Therefore, the floor drain is widely used in areas such as a toilet, a kitchen, and a balcony of a residential building. With the improvement of living standard of people, the washrooms of the residences are usually obviously divided into wet areas (namely the washrooms) and dry areas (namely normal activity places), the ground of the dry areas is usually cleaned by using a mop, and no ground water needs to be discharged to a drainage system; therefore, the floor drain arranged in the dry area only plays a role of connecting the washing machine or the hand washing basin for drainage actually; similarly, the floor of the kitchen of the current residential home is usually cleaned by using a mop, and no floor water needs to be discharged to a drainage system; thus, the floor drain arranged in the kitchen only actually plays a role of connecting the vegetable washing basin for draining.
The floor drain used by the residents has the four characteristics of quick drainage, odor prevention, blockage prevention and easy cleaning. The existing various floor drains directly use the drain pipe to drain to the ground or the floor drain when receiving the drainage of the clothes washing machine, the hand washing basin or the vegetable washing basin; because the upper part of the floor drain is open, water stains, solid matters and sediments generated in the using process can easily enter the floor drain after the floor drain is used for a period of time; the hand washing basin is easy to generate hair and fiber matters, the vegetable washing basin is easy to generate grease and food residues, and the dirt is often accumulated at the bottom of the floor drain and on the pipe wall of the floor drain, so that the floor drain drains slowly and emits peculiar smell outwards; due to the special structure of the floor drain, the floor drain is difficult to clean and even can cause blockage. A wall cabinet and a cupboard are arranged above the local floor drain, so that floor drain cleaning and blockage disposal become more difficult problems.
