A mounting support protrusion protrudes inward to support the mounting.
An anti-lifting protrusion 11 is provided on the inner surface of the instrument body 1 above the mounting support protrusion to abut against the upper part of the ridge 8 of the waste container 4 to prevent the waste container 4 from rising. A vertical passage 1 having a width wider in the circumferential direction than the anti-lifting protrusion 11 on the ridge 8
2, and then insert the waste container 4 into the device main body 1 by aligning the vertical passage 12 with the anti-lifting protrusion 11, and then rotate the waste container 4 in the circumferential direction so that the flange 8 of the waste container 4 The upper end is located below the lower end surface 11a of the lifting prevention protrusion 11, and even if a lifting force is applied to the garbage container 4 by the water in the trap, the protrusion 8 comes into contact with the lifting prevention protrusion 11. A configuration has been considered and proposed to prevent the garbage container 4 from floating up, but in such a configuration, although the flange 8 of the garbage container 4 is cut out in the circumferential direction to form the vertical passage 12, this vertical passage is At 12, the thickness of the garbage container 4 becomes thinner,
The strength of the vertical passage 12 portion is weakened, and if another object collides with this portion or stress concentration occurs, cracks a etc. easily occur and deform, and the vertical passage 12 rises up and meets the prevention protrusion 11. Garbage container 4
When the garbage container 4 is pulled upward, the deformed portion b collides with the lower surface 11a of the anti-lifting protrusion 11, causing a problem that it becomes difficult to remove the garbage container 4.

[Purpose of the invention] The present invention was created in view of the above problems, and its purpose is to reliably prevent garbage containers from floating up, while also preventing garbage from rising in the vertical passage. To provide a drainage device from which a garbage container can be easily removed even if the container becomes thin and deforms at this location.

[Disclosure of the invention] The drainage device of the present invention has a trap tube 3 erected upwardly inside the periphery of the drain port 2 at the bottom of a cylindrical device body 1, and is inserted into the device body 1 in a freely removable manner. A drainage hole 6 is formed in the peripheral wall 5 of the bottomed cylindrical garbage container 4, and a trap tube 3 is formed downward from the bottom of the garbage container 4.
A trap outer cylinder 7 having a larger diameter than that of the trap is hung down, a projecting edge 8 protruding outward is formed on the outer periphery of the upper opening edge of the garbage container 4, and the projecting edge 8 is mounted on the inner periphery of the upper opening edge of the instrument body 1. A mounting support protrusion 10 to be supported is made to protrude inwardly, and the upper part of the ridge 8 of the waste container 4 is brought into contact with the inner surface of the instrument main body 1 above this mounting support protrusion 10, so that the waste container 4
Lifting prevention protrusion 11 that prevents lifting of
This lifting prevention protrusion 11 protrudes inward.
An inclined surface S whose thickness becomes thinner toward the lower end is formed on the inner surface of the container, and the lower part of the inclined surface S is gently connected to the inner surface of the device main body 1, and the ridge 8 of the garbage container 4 is provided with a circumferential direction from the anti-lifting protrusion 11. A vertical passage 12 with a wide width is formed in the container body 1, and the flange 8 of the waste container 4 inserted into the device body 1 is placed on the mounting support protrusion 10, and the flange 8 is positioned below the lifting prevention protrusion 11. ,
The trap 13 is formed between the trap tube 3 and the trap outer tube 7 by positioning the lower edge of the trap outer tube 7 below the upper edge of the trap tube 3. By configuring this, the above objective has been achieved. That is, a projecting edge 8 protruding outward on the outer periphery of the upper opening edge of the garbage container 4
By forming an anti-lifting protrusion 11 inwardly protruding from the inner surface of the device main body 1 to abut against the upper part of the flange 8 of the waste container 4 to prevent the waste container 4 from rising. Even if the garbage container 4 is lifted by the water and a force is applied, the lifting prevention protrusion 11 can reliably prevent the garbage container 4 from floating, and thus the garbage container 4 can be prevented from floating. By making the garbage container 4 lightweight, for example, made of synthetic resin, the cost can be reduced compared to one made of stainless steel.In addition, the slope S is formed by forming an inclined surface S on the inner surface of the anti-lifting protrusion 11, the thickness of which becomes thinner toward the lower end. By arranging the lower part of the garbage container 4 loosely along the inner surface of the device body 1, when the garbage container 4 is pulled upward and taken out, the vertical edge 8 formed on the rim 8 of the garbage container 4 over a wide width in the circumferential direction is formed. The thickness of the passage 12 is reduced, and even if a crack or deformation occurs in this part, the deformed part of the inclined surface S, which is flush with the inner surface of the instrument main body 1, will be smoothly guided. This allows the garbage container 4 to be easily taken out.

Embodiments of the present invention will be described in detail below based on the drawings.

Drainage device A is composed of a cylindrical device body 1 and a garbage container 4 which is inserted into the device body 1 in a freely removable manner. At the top of the instrument body 1 is a tsuba 15.
is formed so that it can be mounted and supported on the receiving stage part of the sink 16. A drain port 2 is formed at the bottom of the device main body 1, and a hose connection port 14 is formed below the drain port 2 to connect a drain hose (not shown) to drain water. A trap cylinder 3 is installed upwardly at the peripheral edge of the drain port 2. Further, a side inlet 17 is formed in the side wall of the appliance main body 1, and drainage from a small sink formed next to the sink 16 is allowed to flow into this side inlet 17 via a drainage hose. It is designed to allow drainage. This side inlet 1
7 may not be formed.

A large number of drainage holes 6 are formed in the peripheral wall 5 of a bottomed cylindrical garbage container 4 which is inserted into the device main body 1 in a freely removable manner. The bottom part 9 of the waste container 4 does not have a drainage hole 6, and is small so as to prevent waste from being mixed with wastewater and discharged. A trap outer cylinder 7 having a larger diameter than the trap cylinder 3 is suspended downward from the bottom part 9 of the garbage container 4. A projecting edge 8 that projects outward is formed on the outer periphery of the upper opening edge of the garbage container 4. A mounting support protrusion 10 for mounting and supporting the projecting edge 8 is projected inward from the inner periphery of the upper opening edge of the instrument main body 1. On the inner surface of the instrument main body 1 above the mounting support projection 10, a lifting prevention projection 11 is projected inward to abut against the upper part of the flange 8 of the garbage container 4 to prevent the garbage container 4 from lifting up. and the rim 8 of the garbage container 4
A vertical passage 12 having a width wider in the circumferential direction than the anti-lifting protrusion 11 is formed in the vertical passage 12 of the flange 8 of the waste container 4 inserted into the device main body 1.
2 through the anti-lifting protrusion 11, the protrusion 8 is placed on the mounting support protrusion 10, the waste container 4 is supported in a suspended state inside the device main body 1, and the waste container 4 is rotated left and right. Then, the upper edge of the projecting edge 8 is brought into contact with the lower edge of the lifting prevention protrusion 11, and the garbage container 4 is held in a state where the lifting of the garbage container 4 is prevented.
The installation of the device onto the main body 1 of the device is completed. In such a case, the trap outer cylinder 7 is located outside the trap cylinder 3, the lower edge of the trap outer cylinder 7 is located below the upper edge of the trap cylinder 3, and the trap 13 is located between the trap cylinder 3 and the trap outer cylinder 7. is formed.

The appliance body 1 and the garbage container 4 are molded products made of synthetic resin, and by making the garbage container 4 of metal such as stainless steel, manufacturing problems and cost disadvantages can be avoided, and the weight and cost can be reduced. It's down. Further, the anti-lifting protrusion 11 has a stop 18 integrated therewith hanging down about the vertical height of the protrusion 8, so that the garbage container 4 can be secured to the main body 1 of the appliance.
When rotated relative to the garbage container 4, one end edge of the vertical passage 12 of the projecting edge 8 comes into contact with the abutment 18, so that the rotational position of the garbage container 4 can be determined. And a mounting support protrusion 1 formed on the instrument body 1
0, a notch 19 is formed below the anti-lifting protrusion 11 and the abutment 18 formed on the instrument body 1 over an area longer than the total length of these in the circumferential direction. 1
By forming 9, it is possible to easily separate (cut out) the upper and lower molds (not shown) of the mold for molding the instrument body 1, and the instrument body 1 is made of synthetic resin. This also reduces molding problems caused by manufacturing. Such a mounting support protrusion 10 and lifting prevention protrusion 11
The positioning member 23 for the waste container 4 having the contact 18 is integrated by screwing a male thread 25 formed on its outer periphery into a female thread 26 on the upper part of the main body member 24. In this way, the device main body 1
The ease of molding is also improved by separating the body member 24 and the positioning member 23.

The garbage container 4 is provided with a handle 22 so as to be able to stand up and rotate, so that the garbage container 4 can be taken out from the instrument body 1 by holding the handle 22. Further, a perforated plate 27 is removably attached to the upper opening of the drainage device A attached to the sink 16.

In the above configuration, the present invention forms an inclined surface S on the inner surface of the anti-lifting protrusion 11, the thickness of which becomes thinner toward the lower end, and the lower part of the inclined surface S is connected to the instrument main body.
By connecting the lower part of the slope S to the inner surface of the device main body 1 in this way, when the garbage container 4 is pulled upward and taken out, the garbage container 4 is The thickness of the vertical passage 12 formed in the flange 3 over a wide width in the circumferential direction is thinner, and even if a crack or deformation occurs in this area, it will remain flush with the inner surface of the instrument body 1. The deformed portion is smoothly guided by the inclined surface S, which makes it easy to take out the garbage container 4.

[Effects of the invention] In summary, the present invention forms an outwardly protruding rim on the outer periphery of the upper opening edge of the garbage container, and abuts the upper part of the rim of the garbage container on the inner surface of the device body to raise the garbage container. Since the anti-floating protrusion protrudes inward to prevent floating, even if a flotation force is applied to the garbage container by the water built into the trap, the anti-floating protrusion will surely prevent the garbage container from floating. Since it is possible to prevent the garbage container from floating in this way, it is possible to make the garbage container lightweight, for example, made of synthetic resin, reducing the cost compared to stainless steel. Since the lower part of the slope is gently connected to the inner surface of the main body of the device, the projecting edge of the garbage container has a wide width in the circumferential direction. The thickness of the vertical passageway is thinner, and even if cracks or deformation occur in this area, the deformation area will be smooth on the sloped surface that is flush with the inner surface of the device body. There is an advantage that the waste container can be easily removed by being guided.
