Description

The invention relates to a lined drain channel according to the preamble of Claim 1. Such a drain channel is for example known from EP 1630309 and EP 2808457. KR 20100000160 U discloses an open type drain trench installed on a floor of a bathroom, which trench has a drain path and a drain trap coupled to an arbitrary position of the drain path. A drain cover provided with holes covers the drain trap while not the drain path leading to the drain trap. Support protrusions forming upright walls are provided on both sides of the drain path along its complete length. In for instance a shower space or a bathroom it is usual to tile the floor with tiles. A collecting tray is here arranged in the floor so that water falling on the floor, for instance from a shower head, can be discharged in an outlet pipe. It is known to use an elongate shower drain as collecting tray. The advantage of an elongate shower drain is that an inclining surface, which is flat and can be lined with large tiles in simple manner, can be arranged adjacently. Often placed in the longate shower drain is a stainless steel grating, through which the shower drain is clearly visible. In such an elongate shower drain hairs and dirt will stick to the underside of the grating, particularly to the adjusting feet of the grating. This is difficult to clean, and thereby less hygienic. It is however a trend to conversely make the drain element less visible in the covered floor, such as a tiled floor. It is known for this purpose to place a so-called tile grating in an elongate shower drain. This is an element which is lined with a tile, and largely covers the inflow opening of the shower drain and leaves only small inflow gaps. A drawback of such a tile grating is that it is difficult to remove when the shower drain has to be inspected and cleaned. The use of a smaller collecting tray in combination with relatively large tiles is difficult, since the large tiles have to be cut into many pieces for the purpose of providing a good downward incline toward the collecting tray. This is because it is necessary in the case of a smaller collecting tray to provide various inclining surfaces, each having a downward inclining direction toward the smaller collecting tray. In addition, it is known in for instance sports facilities to provide a recess, which forms a discharge channel, in the cement floor. Arranged in the bottom of this recess is a drain which protrudes with the upper edges above the bottom surface of the cement floor so that, when the bottom surface is tiled, the upper surface of the tiles connects to the upper edges of the drain. In such a construction the drain is in fact arranged in the same way as in a normal tiled floor. The drawback of this construction is that the discharge channel must be formed in the floor during the work, while the drain is manufactured in the factory. A good seal between the discharge channel and drain is hereby difficult, and it is difficult to provide a correct incline in the discharge channel so that collected water is discharged to the drain properly. In addition, the drawback of such a construction is that the width of the discharge channel is relatively great because a drain with standard dimensions must be arranged in the recess and a good seal must also be provided. Further known are shaped metal drain strips which are provided in a central part with an opening which connects to an outlet pipe. It is essential precisely in the case of such metal drain strips that, from a design viewpoint, the metal drain strips remain visible. It is therefore usual when installing these drain strips to make the upper edges of the strips flush with the upper surface of the surrounding floor. In these drain strips the roughness of the metal surface, the so-called R-value, is low compared to the roughness of tiles. This can cause a user to slip when he or she steps from the surrounding floor onto the metal drain strip. It is now an object of the invention to reduce or even obviate the above stated drawbacks. This object is achieved with a lined drain channel according to claim 1. Because the elongate bottom surface is at a first end side arranged on an upper edge of the collecting tray, one whole is obtained, this forming the drain channel. Since the drain channel is manufactured in the factory, the discharge channel and the collecting tray can be adapted to each other in simple manner, whereby a good seal, a correct incline in the discharge channel and a good discharge of water can be ensured. Now that the drain channel itself is provided with a discharge channel at least one plate-like lining element, such as a tile, is arranged herein on the bottom surface. The at least one plate-like lining element will hereby simply lie at the correct incline, without special attention having to be paid thereto during the work. The chance of leakage will further decrease owing to the discharge channel. Even when the at least one plate-like lining
