NL1033684C2 - Drain system for sanitary installation, e.g. sink, includes integral odor trap formed by water reservoir between raised bulkhead and suspended intermediate plate - Google Patents

Abstract

A surface (3) slanting at an angle discharges water towards a drainage channel, after which is a raised bulkhead that creates a permanent water reservoir in front of it. The bulkhead combines with a suspended intermediate plate extending several cm into the reservoir to form an airtight odor trap. A drainage pipe (1) follows the odor trap in this system.

Description

Patent application

Brief description: Integrated odor trap in sanitary applications. Description 1) The invention refers to sanitary ware, such as washbasins, washbasins, shower floors and similar applications.

2) Previously designed sanitary applications consist of sloping trays or 10 surfaces in the direction of a drain hole. A stench trap, often in the form of a trap, is attached under this hole.

3) With classic designs the drain is visible. The siphon is also visible in applications such as washbasins or washbasins. The location of the siphon is also for example for cleaning work in an annoying place and is not easily accessible.

4) New designs have focused in particular on covering the drain, so that the sink has a cleaner and more hygienic appearance. The drain is concealed from the eye by means of cover plates or grilles. Another finding that has already been made is the creation of a stench trap in horizontally placed discharge pipes.

5) An aim of this new application is to keep the drain out of sight.

6) A second goal is to simplify the accessibility of the odor trap, by gaining access to the system from above.

7) A further aim is to integrate the entire system with the plumbing and to manufacture it from 1 whole, so that no extra connections have to be used.

8) The above goals have been achieved with the drain system described in claim 1.

9) Other advantageous features will emerge in the remaining claims.

10) The integrated drainage system is integral with the plumbing and is located at a low part of the application where the water flows away. There is a standing partition in the drainage system, for which a permanent amount of water remains. An angled plate is placed above the bulkhead, which partially hangs in the water reservoir. Waste water flows over the partition to the drain at the bottom of the container on the wall side. The whole is closed by a cover plate, to keep the system hidden from the eye.

11) The design and operation will be further explained, referring to the attached drawings, where:

Figure 1 is a side view of a sink with integrated siphon action with a tap, drain and wall included in the drawing;

Figure 2 is a cross-sectional view of the siphon system on the side of the drainage gutter;

Figure 3 is a top view of a washbasin with integrated odor trap;

Figure 4 is a top view of the odor trap without cover plates.

1033684 2 12) Referring to the figures, Figure 1 shows an overview of an entire sink with an integrated odor trap. The tap and drain are also drawn in, but can have almost any other desired shape.

13) Figure 2 shows a detailed image of the odor trap with siphon action 5. The bottom of the sanitary application [3] slopes obliquely towards the drainage at a small angle. The water falls through a narrow opening [5] in the first part [1], where it is blocked by a raised partition [9]. The curved plate [7] divides the first reservoir into two parts and covers the space behind the plate [14], attached with a screw [8] to a horizontal edge [10].

14) By creating two separate parts of water [11] [13] with a partition wall [7] in between, a siphon effect is achieved. The water level will rise to the top of the partition [9]. By hanging the curved plate [7], which rests on an edge [10] and is properly attached to it, in the liquid, the system is sealed airtight and any stench from the drain is sealed off from where the sanitary is located.

15) Flow of the water will go through the path for a cover plate [6], the two airtightly sealed and separated reservoirs [11] and [13], over the partition [9] and finally via a low level of liquid [12] to be discharged through the drain pipe [1]. Many different forms are possible, while maintaining the principle of an integrated siphon system.

16) Creating a narrowing in the flow [17] results in a higher speed of the water at that location. Any residual dirt in the compartment [11] is washed away by the higher water flow. Manually cleaning the trap is therefore less frequently necessary.

17) The trap system is very easy to dismantle, because the plates can be removed from above. The intermediate plate is fixed to the box with two screw connections and can simply be removed from the system.

18) By covering the siphon system with a cover plate [6], no drain is visible to the user, which is a better view than with conventional drain systems. This cover plate is loose on the trap system and is easy to remove. The plate can optionally be fixed with, for example, a screw connection.

19) The integrated odor trap can be fitted in many sanitary applications and can be produced in many different shapes and sizes, whereby the drain and the trap are always invisible to the eye.

20) The tray, shown angled in Figure 1, can take other forms if desired, vary in length, width and depth or, for example, run towards the center.

21) The intermediate plate, which provides the stench trap, can also be designed differently, such as a different angle at the bend, provided there is enough room for the water to pass through the system at [11] and [13] and the long enough to ensure an airtight seal.

22) The width of the siphon system can be varied, depending on the desired application and the amount of water that must be drained per unit of time. The position of the system can also be shifted, for example on the side of a washbasin. Applications are conceivable in which the system is mounted in a corner, for example with 5 shower floors.

23) A large number of other modifications can be made within the scope of this invention.

Claims (7)

A drainage system part of a sanitary application, characterized in that in the application a surface drains water at an angle towards a drainage gutter, behind which a drainage system has been created with an upright baffle, so that a permanent reservoir of water remains in front of this baffle which, in combination with an intermediate plate which hangs a few centimeters in the reservoir, forms an airtight odor trap, behind which the discharge system changes into a discharge pipe. 2. A drainage system as claimed in claim 1, characterized in that after leaving the sanitary application there is a connection for connecting a drainage pipe and no other odor-trap valves have to be mounted. A drainage system according to claim 1, characterized in that the drainage system is simply closed off for the user's sight and can be easily dismantled. 4. A drainage system according to claim 1, characterized in that it is manufactured from a whole, on which only the intermediate plate has to be fitted, and therefore the risk of leaks is not present. 5. a drainage system according to claim 1, characterized in that by molding from one piece both optical, functional and constructional requirements are necessarily combined in 1 design 6. a drainage system according to claim 1, characterized in that it forms an inseparable part of a sanitary application and can function self-supporting on any surface, wood, stone or any other material, or self-supporting on the wall. 7. A drainage system according to claim 1, characterized in that it rinses itself clean during use due to a higher throughput speed of the water at places where narrowings are arranged. A ratio has been chosen here between the reservoir (11) and the height of the overflow baffle (9) and the depth of the immersed plate (7 = stench trap) that, despite the acceleration that arises with the associated water mass, after the water comes to a standstill sufficient water has remained in the reservoir to continue to comply with the European standard as laid down in the standard at all times; 30 EN 1253-1 2003D / page 9 Articles 8.3 and 8.4. Sanitary applications such as washbasins, washbasins, shower floors and the like, characterized in that a drainage system according to the above claims is integrated herein.
