Description

The present invention relates to a drain drain groove member used when drain water from hot water supply equipment such as an apartment house is drained to an outdoor floor surface of a common corridor.

Examples of the conventional drainage drain member include a drainage drain member used when draining drain water from an outside unit of an air conditioner as described in Patent Document 1 below. The drain drainage channel member includes a water passage member having a drainage channel extending in the longitudinal direction for draining drain water, and a lid member that covers the drainage channel from above, and is horizontally formed on both side walls of the drainage channel. The lid member having both edges inserted into the groove is slidable in the longitudinal direction with respect to the water-passing member so that the lid member can be attached and detached (see, for example, FIG. And FIG. 5).

Japanese Patent No. 4818684

Usually, more drain water is discharged from the hot water supply equipment than the outside unit of the air conditioner. For example, when bath heating, dish washing, etc. are performed at the same time, a relatively large amount of drain water of about 30 mL/min is discharged from the hot water supply facility.

Since the amount of drain water discharged from the outside unit of the air conditioner is smaller than that of the hot water supply equipment, it is basically difficult to handle a large amount of drain water. For example, in winter, when the outside air temperature decreases at night, the drain water remaining in the drain tube that connects the hot water supply equipment and the drain drain groove member freezes. Then, when the temperature rises during the daytime, the frozen drain water gradually melts from the hot water supply equipment side, and finally the tip portion melts, so that a large water pressure is applied to the drain water flowing into the drain drain groove member. As a result, water pressure acts from the inside of the drain drain groove member in the up-down direction and the width direction, so that a gap is easily formed between both edge portions of the lid member and the groove portion of the water passage member, and the drain water is drained from the gap. May leak out.

Therefore, an object of the present invention is to improve the watertightness of a drain drainage channel member including a water passage member having a drainage channel and a detachable lid member that covers the drainage channel and to store a large amount of drain water. It is to be applicable even when draining.

The characteristic configuration of the drain drainage channel member of the present invention is a drain drainage including a water passage member having a drainage channel extending in the longitudinal direction for draining drain water, and a detachable lid member that covers the drainage channel. In the groove member, the water passage member has a longitudinal groove extending in the longitudinal direction outside the drainage channel, and ribs projecting inward of the longitudinal groove and extending in the longitudinal direction are provided on both side walls of the longitudinal groove. The two ribs are elastically deformable so that the distance between them is separated by applying a predetermined load from the vertical direction, and the lid member projects downward and extends in the longitudinal direction. Has a portion on the back surface, the ridge portion has a small diameter portion and a large diameter portion on the base end side and the tip end side, respectively, when the ridge portion is accommodated in the vertical groove, The two ribs are in contact with a step formed by the small diameter portion and the large diameter portion ,
A gap is provided between at least one of the side wall and the bottom surface of the vertical groove and the large diameter portion .

[Action and effect]
According to this configuration, since the double seal is formed by the contact between the step portion of the protruding portion of the lid member and the two ribs of the water passage member, the water tightness between the lid member and the water passage member is formed. The nature is enhanced. In other words, even if the drain water should leak over the rib provided on the side wall of the vertical groove near the drainage channel, the leakage of the drain water should be prevented by the seal of the other rib. You can
In addition, even if a large amount of drain water that is under a large water pressure flows into the drainage channel and water pressure acts from the inside of the drain drain groove member in either the vertical direction or the width direction, the step of the ridge portion The degree of contact between the rib and the two ribs of the water passage member is further strengthened. That is, with respect to the pressure in the vertical direction, the degree of close contact between the lateral surface of the step and the rib becomes strong, and with respect to the pressure in the width direction, the degree of close contact between the vertical surface of the step and the rib becomes strong. Therefore, the watertightness between the lid member and the water passage member is further enhanced, and the drain water can be reliably prevented from leaking.
On the other hand, when removing the lid member from the water-passing member, if the worker pulls out the lid member with a force of a predetermined load or more, the ribs are elastically deformed and separated from each other, and the rib having a large diameter portion has two ribs. The lid member can be removed because it becomes possible to pass through between them.
Further, according to this configuration, even if the drain water should leak over the rib provided on the side wall of the vertical groove that is close to the drainage channel, the leaked drain water will leak into the vertical groove. Can be drained through the gap .

The characteristic configuration of the drain drainage channel member of the present invention is a drain drainage including a water passage member having a drainage channel extending in the longitudinal direction for draining drain water, and a detachable lid member that covers the drainage channel. In the groove member, the water passage member has a longitudinal groove extending in the longitudinal direction outside the drainage channel, and ribs projecting inward of the longitudinal groove and extending in the longitudinal direction are provided on both side walls of the longitudinal groove.
