Description

A bottom-draining anti-drying floor drain

Technical Field

The utility model relates to the field of construction, in particular to a bottom-draining anti-drying floor drain for building drainage.

Background Art

The floor drain is an important drainage device for the bathroom and kitchen floor in a building. When the building drainage pipe is drained, the airflow in the pipe will produce pressure fluctuations. If there is no obstruction, the harmful exhaust gas in the pipe can easily overflow into the room through the drainage device. In order to prevent these harmful exhaust gases from entering the room, a water seal device with a certain water level depth must be set between the sanitary ware, floor drain, etc. and the drainage branch pipe. For example, patent publication number: 203878722U discloses an anti-drying and anti-overflowing floor drain, in which an anti-drying float and an anti-overflowing float are respectively set in its water seal assembly. That is, it ensures the normal drainage function of the floor drain, and can automatically close the floor drain drainage channel when the floor drain is not drained, prevent the water seal from evaporating and drying, and prevent the water seal from being lost due to negative pressure suction, and can also prevent positive pressure splashing and overflow of sewage from the floor drain. However, when the drainage flow rate is large, the vortex water flow formed in the water inlet will suck the anti-drying float downward and seal the mouth of the water seal cylinder, resulting in poor drainage. In addition, the design structure is complex and the drainage resistance is large.

Utility Model Content

The utility model aims to provide a bottom-draining anti-drying floor drain, which can prevent the water seal from evaporating and drying up while ensuring smooth drainage.

In order to achieve the above purpose, the utility model adopts the following technical solutions:

A bottom-drainage anti-drying floor drain comprises a floor drain body, a bottom drainage interface, and an upper water inlet, wherein the bottom drainage interface is below the floor drain body, the upper water inlet is above the floor drain body, and the periphery of the upper water inlet is installed on the ground through a panel, and further comprises a stainless steel grate, a panel, a filter basket, a sunken drainage trough, and a water seal assembly; the water seal assembly comprises an outer core, an inner core, a float, and a water stop valve, the water seal assembly is inserted into the floor drain body, the sunken drainage trough is provided with an upper end of the floor drain body, the panel is placed on the upper end of the sunken drainage trough, a filter basket is placed inside the panel, the filter basket is embedded in the sunken drainage trough, a stainless steel grate is installed on the upper end of the filter basket, an outer core is placed on the lower end of the filter basket, an inner core is installed inside the outer core, a float is placed below the water inlet of the inner core, and a water stop valve is installed on the lower end of the float and the inner core.

Preferably, the top surface of the upper water inlet is slightly lower than the large surface of the panel, and the panel is lower than the ground, so as to facilitate the flow of water into the floor drain on the ground.

Preferably, the lower end of the sunken drainage trough is inserted into the floor drain body, and the upper end skirt is placed at the mouth of the floor drain body.

Preferably, the float is made of lightweight plastic or lightweight rubber material and has a hollow structure and can float on water.

Preferably, the diameter of the water inlet of the inner core is about one third of the diameter of the float, the size of the lower end of the inner core is larger than the diameter of the float, and the water-passing gap between the float and the inner wall of the inner core is not less than 8 mm.

Preferably, the outer core and the inner core are assembled by snap-fitting, the inner core is inserted into the outer core, and the inner core and the outer core are concentric.

Preferably, a water stop valve is installed at the lower end of the inner core. The water stop valve is a double-opening semicircular structure. The bottom end of the water stop valve is installed on a steering shaft. The steering shaft is fixed on both sides of the inner core. A compression spring is installed on the steering shaft to control the switch of the water stop valve.

Preferably, the water outlet hole of the outer core is located in the upper half of the outer core, and the bottom end of the water outlet hole is flush with the bottom end of the one-third point when the float floats up to the mouth.

Compared with the prior art, the beneficial effects of the utility model are as follows:

The utility model discloses a bottom-draining anti-drying floor drain. When draining water, the water pressure causes the float to sink and the water stop valve to open, thereby ensuring the normal drainage function of the floor drain. When there is no drainage, the water stop valve is closed and the float floats up to seal the inner core opening, thereby preventing the water seal from evaporating and drying up and preventing the water seal from being lost due to negative pressure suction. It can also prevent positive pressure splashing and overflow of sewage from the floor drain. It ensures that the water seal of the floor drain always maintains a safe depth and avoids the occurrence of odor from the floor drain.

The utility model discloses a bottom-draining anti-drying floor drain. When draining water, water impacts the float 603, the float 603 sinks, the gravity of the water increases, the valve on the water stop valve 604 rotates downward, the valve opens, and the water flows into the outer core 601. With the increase of water, the excess water overflows from the water outlet 606 of the outer core 601 and flows into the outlet pipe 8. When the water in the outer core 601 does not exceed the lower mouth of the water outlet 606, the water in the outer core 603 closes the valve on the water stop valve 604. At this time, the float 603 floats up and seals the mouth of the inner core 602, so that the water can be prevented from evaporating and drying up and the water seal loss caused by negative pressure suction can be prevented. It can also prevent positive pressure splashing and overflow of sewage from the floor drain. A filter basket 3 is placed on the inner side of the panel 2. The filter basket 3 can filter impurities contained in the water, prevent hair and other debris from being stuck around the float 603, so that the float 603 cannot play a sealing role. The filter basket 3 has a certain depth and is convenient to be taken out and cleaned. Multiple protections ensure that the water seal of the floor drain always maintains a safe depth, avoiding the occurrence of odor from the floor drain.
