Description

[Detailed Description of the Invention] The present invention relates to an improvement of a drainage trap for draining general miscellaneous water, and is intended to eliminate clogging in the trap.

Traditional bowl-shaped traps must be cleaned from time to time because foreign objects can accumulate inside the trap, causing blockages and resulting in poor ice flow.

The present invention is intended to eliminate the above-mentioned drawbacks, and one embodiment will be described in detail below with reference to FIGS. 1 and 2.

In the figure, reference numeral 1 denotes a trap body case which is fixed to a floor 2 etc. with a locking fitting 3.

4 is a sealant and 5 is a screen.

Inside the drain trap body case 1, there is a drain guide member 6.
The upper end of this drainage guide member 6 is fixed to the inner wall of the drain trap main body case 1, and has a mouthpiece hanging down at the lower end, and this mouthpiece is connected to the drainage inlet side (in the drawing, the upper side ) is opened and water can be stored in the bowl-shaped odor prevention lid 7.
It is inserted into the tank from above so that it is slightly below the surface of the collected water.

The odor rise prevention M7 is fixed by a fixing bolt 10 to an end of a rotating shaft 9 of an electric motor 8 disposed below.

Reference numeral 11 denotes a motor fixing metal fitting, which is fixed to the case 1 by a locking metal fitting 12, and the electric motor 8 is installed in the lower part of the main body case 1.

13 is an oil seal, and 14 is a drain pipe connection port.

To explain the action of the trap configured as above,
Sewage drained onto the floor 2 etc. passes through the screen 5, passes through the drainage guide member 6, and enters the odor rise prevention lid 7.

Normally, the odor rise prevention lid 7 is stopped, and the sewage that has entered here overflows and is drained to the drain pipe connection port 14.

Incidentally, when dirt accumulates in the odor rise prevention lid 7 and the drainage capacity decreases, the electric motor 8 is rotated to rotate the odor rise prevention lid 7.

When the odor rise prevention lid 7 rotates, the dirt and water inside the odor rise prevention lid 7 are blown away in the radial direction by the centrifugal force, and the odor rise prevention lid 7 is cleaned and drain guide member 6
The end of the trap is also washed with high-speed running water and once again performs its intended function as a trap.

FIG. 2 shows an embodiment in which a drain trap is attached to a kitchen waste disposal machine. Reference numeral 15 is a hopper of the kitchen waste disposal machine, and the upper end is attached to a sink 16 with a locking fitting 17.

Reference numeral 18 denotes a rotating disk fixed to the electric motor 8 and rotating shaft 9 with fixing bolts 10. A plurality of rotary teeth 19 for processing kitchen waste are provided on the outer circumference of the rotating disk, and a plurality of rotating teeth 19 for processing kitchen waste are provided on the inner circumferential surface of the hopper 15 facing thereto. is provided with vertical groove-shaped fixed teeth 20 around the entire circumference, and rotary teeth 19
A slight gap 21 is formed between the fixed tooth 20 and the fixed tooth 20.

7 is a drainage guide member that extends slightly downward into the odor rise prevention lid 7 fixed to the rotating shaft 9 below the rotating disk 18, and the other end is connected to the fixed teeth 20 and the lower hopper 15.

22 is connected to the hopper 15 and the electric motor 8 through a casing.

23 is a scattering plate fixed to the rotating shaft 9.

Next, the operation of the kitchen waste disposal machine configured as described above will be explained.

When the electric motor 8 is operated and kitchen waste is supplied to water from the inlet 24, the kitchen waste is blown away by centrifugal force to the outer periphery of the rotary teeth 19 in the radial direction, and is ground between the rotary teeth 19 and the fixed teeth 20 to become a pulverized solution. The lid 7 prevents odor from rising through the drainage guide member 6.
The entered kitchen waste solution is blown away in the radial direction by the centrifugal force of the odor rise prevention cover 7 rotating at the same speed as the rotating shaft 9, passes through the casing 22, reaches the drain pipe connection port 14, and is discharged into the sewage.

On the other hand, when the electric motor 8 is stopped, the kitchen waste is
Since the gap 21 between the rotary teeth 19 and the fixed teeth 20 is small even when the garbage is poured in from the above, kitchen waste is retained above the rotary teeth 19, and other general waste water passes through the gap 21 and is removed from the odor rise prevention lid 7. However, since the centrifugal force does not work while the odor is stopped, it overflows the odor rise prevention lid 7, flows into the casing 22, and is drained into the drain pipe connection port 14.

As explained above, in the present invention, by rotating the odor rise prevention lid 7, the foreign matter adhering to the inside of the trap can be shaken off by centrifugal force, and the inside of the trap can be washed.

Furthermore, when combined with equipment such as a kitchen waste disposal machine, it has the remarkable effect of being able to achieve the purpose at low cost.
