Abstract

PROBLEM TO BE SOLVED: To lessen the residue in a drainage even when drain is a little and sufficiently wash bubbles out by forming the sectional shape of the drainage so as to make narrower the breadthwise width of the ditch bottom than that of the upper end opening in the upstream side and make wider the breadthwise width of the ditch bottom in the downstream side. SOLUTION: The drainage 5 is formed to have a V-shaped section in the upstream thereof so that water is hardly disconnected and the breadthwise width L of the ditch bottom of the drainage 5 is widened as it goes to the downstream. Accordingly, water does not spread widely on the ditch bottom 5C even when drain is a little in the drainage 5 in the upstream where only a relatively small quantity of drain flows in, and the contact resistance against the ditch bottom 5C is small and water continuously flows without disconnection in the midway of the stream. In the drainage in the downstream, as bubbles do not touch the side wall 5D of the drain ditch and the quantity of water increases compared with the upstream, the water stream is not disconnected. In this way, even when drain is a little, the residue in the drainage can be decreased.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a drainage structure for a bathroom.

[0002]

2. Description of the Related Art The cross-sectional shape of a groove in a drainage channel is constant from upstream to downstream, and the lateral width of the groove bottom and the lateral width of the upper end opening are formed to be substantially the same width. For example, as shown in FIG. 10, the groove width L was constant from the upper end opening to the groove bottom.

[0003]

Then, the lateral width of the groove bottom is formed wide, and when the amount of water is small,
Since the drainage spreads flat across the width of the bottom of the groove, the resistance of the bottom of the groove is effective, and the drainage is disconnected and does not flow. SUMMARY OF THE INVENTION An object of the present invention is to provide a bathroom drainage channel structure that can sufficiently remove bubbles while minimizing the remaining amount in the drainage channel even if the amount of drainage is small.

[0004]

According to a first aspect of the present invention, there is provided a drainage passage for guiding water from a washing place toward a drainage outlet, and a cross-sectional shape of the drainage passage is set to an upstream side. In the point that the width of the groove bottom is narrower than the width of the upper end opening, and on the downstream side, the width of the groove bottom is wider than the width of the upstream side. The effects are as follows.

[Operation] In other words, in the upstream drainage channel where the amount of drainage flowing is relatively small, the width is narrow at the bottom of the groove, so that even if the amount of drainage is small, the water is shallow to the bottom of the groove. Since it does not spread, the contact resistance with the groove bottom can be reduced, and water is connected and flows without being divided on the way. However, if the state in which the width of the groove bottom is narrow is maintained down to the downstream side, the bubbles that tend to concentrate on the downstream side and float and move on the water surface are more likely to adhere to the side wall of the drain groove. Therefore, in the downstream drainage channel, the width of the groove bottom is made wider than that of the upstream side so that the foam does not contact the side wall of the drainage channel.
In the downstream drainage channel, the amount of water is larger than that in the upstream side, so that the water is not divided on the way.

[Effect] Accordingly, the present invention has provided a discharge channel structure for a bathroom having a high discharge performance even for bubbles which have a small remaining amount in the drainage channel and easily accumulate near the drainage port.

[Structure] A feature of the invention according to claim 2 is that, in the feature of the invention according to claim 1, the groove bottom surface is formed on a surface inclined toward one side end in the width direction. The operation and effect are as follows.

[Effect] In other words, by inclining the groove bottom, which is in a horizontal state in a normal state, toward one side end in the width direction, water spreads shallowly to the groove bottom even if the amount of drainage is small. Since there is no problem, the contact resistance with the groove bottom can be reduced, and water is connected and flows without being divided on the way. Therefore, even if the amount of drainage is small, the remaining amount in the drainage channel can be reduced.

[Structure] According to a third aspect of the present invention, in the characteristic structure according to the first aspect of the present invention, the depth from the upper end opening to the groove bottom is set to be deeper on the downstream side. The operation and effect are as follows.

[Effects] In other words, in response to an increase in the amount of water on the downstream side, water and bubbles, etc. once guided into the drainage ditch fall outside the ditch by increasing the depth to the bottom of the ditch on the downstream side. Overflow is reduced.

[Structure] According to a fourth aspect of the present invention, in the characteristic structure according to the first aspect of the present invention, there is provided a drainage channel for guiding water from the washing place to a drainage port between the washing place and the bathtub. In addition to the above, the introduction inclined surface from the upper edge of the drainage channel on the washing side to the bottom of the groove is provided, and its operation and effects are as follows.

[Operation and effect] In other words, by forming the introduction inclined surface, when drainage flows from the washing place to the groove bottom, the angle of the bend at the upper end opening edge portion becomes gentle. The flowing water is less likely to be divided, and can be easily introduced into the drainage ditch even if the amount of water is small.

A seal is provided between the inner wall and the side wall Wa with a joint material. Despite the presence of the seal, water that has entered the waterproof tub 2 is drained from the drain port 2D, and leakage is prevented. The structure which does not leak to the floor surface F is adopted.

As shown in FIG. 2, the washing unit A
Is a washing basin waterproof pan 4 having a washing basin 4a, and a side wall Wa.
And a washing counter 3 attached and fixed to a side wall Wc disposed adjacent to the washing machine. As shown in FIGS. 1 and 7, shallow drainage channels 5 and 6 are formed on the side of the bathtub unit side and the side of the washing counter 3 in the peripheral portion of the washing pan waterproof pan 4.
Side 4A on the door unit D side facing the side on the washing counter 3 side, and side 4B facing the side on the bathtub unit side
6 are provided with deep drain grooves 4b, 4b, respectively.
As shown in FIG. 5, a sash 10 is provided to cover each of the drains 4b. As shown in FIG. 11, a wall 7A rising upward from the drainage channel 6 and a stage portion 7B extending horizontally from the upper end of the wall 7A are integrally provided on the washing counter side of the washing pan 4. The stage 7B is formed and arranged so as to be located below the washing counter 3. Between the washing counter 3 and the stage 7B, there is formed a storage space for water supply equipment for the caran 8 attached to the washing counter 3, and the storage space is provided between the stage 7B and the washing counter 3 in the vertical posture. 9 is usually fitted and covered.

A first drain port 11 is located at the intersection of the side of the bathtub unit and the side 4A of the door unit D, and a second drain port 12 is located at the intersection of the side of the bathtub unit and the side of the washing counter 3 side. The first drain port 11 drains the washing water collected from the two drain grooves 4b, 4b, and the second drain port 12 drains the washing water flowing from the two drain channels 5, 6 respectively. To do. Each drain ditch 4b, 4b and drain channel 5,
6 are provided with ramps for guiding washing water to the drain outlets 11 and 12, respectively. In particular, in the bathtub unit side drainage channel 5, as shown in FIG.
Is gentle (the inclination α is about 1 degree), and the inclination is steep on the downstream slope 5B of the flow (the inclination α is about 4 degrees). Near the middle position in the flow direction where the two ramps 5A and 5B are connected, a smooth surface that smoothly connects the two ramps 5A and 5B is formed. Ramp 5A, 5 as described above
By setting the slope α of B, even if the amount of drainage decreases, the amount of residual water in the drainage channels 5 and 6 can be reduced, and bubbles can be prevented from remaining. The two drain grooves 4b, 4b each have a constant drain slope in the flow direction, but the downstream drain groove 4b provided on the side 4A on the door unit D side is closer to the bathtub unit side. And is set to be steeper than the upstream drain groove 4b.

FIG. 9 shows the result of measurement of the amount of residual water in the drainage channel 5. According to this, a test was performed in which the inclination, that is, the inclination was in the range of 1 ° to 5 °, and as a result, data as shown in FIG. 9 was obtained. Due to the inclination: 1.0 °: Water flows from above the water to below the water, and remains slightly near the wall. 1.5 °: Water is split at one point. 2.0 °: Water is split at one point. 3.0 °: Divided, but flows down by its own weight depending on the size. 4.0 °: Divided, but flows down by its own weight depending on the size. 5.0 °: Divided at multiple locations. Water drops on the flat surface are noticeable. There are differences as described above. It was found that the remaining amount was small for the water connected and flowing, but when the slope was steep, the water was divided in the middle of the flow and the remaining amount tended to increase. However, in order to prevent the foam which tends to collect in the latter part of the drainage channel 5, especially near the second drainage port 12, it is necessary to flush out the bubbles. In this case, it is preferable that the slope is steep. Therefore, the slopes 5A and 5B in the drainage channel 5 are set as described above.

Another structure of the drainage slope α of the drainage channel 5 will be described. An intermediate ramp having an intermediate gradient between the two ramps 5A and 5B may be further provided between the upstream ramp 5A and the downstream ramp 5B of the drainage channel 5. Thereby, a fine inclination setting corresponding to a drainage tendency in which the drainage amount increases toward the downstream side is possible. Note that a plurality of the intermediate slopes may be provided, and the intermediate slope may be provided infinitely (a state in which the drainage slope is gradually increased from the upstream side toward the downstream side). Although an example of a structure in which drainage slopes are different for the drainage channels 5 and 6 has been described, the drainage grooves 4b and 4b have the same function as a structure for guiding washing water to the drainage port 11 and the like. The present invention may be applied to If the slope of the upstream slope is gentler than the slope of the downstream slope, a slope other than the above may be adopted. The drainage slope of the drainage channels 5 and 6 may be a fixed slope.

In the above case, the results of testing the inclination in the direction along the flow in the drainage channel 5 are shown, but the width of the drainage channel 5 is set as shown in FIG. I have. On the upstream side of the drainage channel 5, as shown in FIG. 10 (b), since the amount of water is small, the cross section is V-shaped and the water is hardly divided,

°) and good drainage. As shown in FIG. 6, a pattern 14 in which a substantially rhombic pattern 14A is regularly arranged is provided between the pen 10 and the washing place 4a. The pattern 14 may be formed either on the surface of the washing room 4a or on the surface of the resin washing room 4a or on the surface of the warehouse 10 by a printing method. Since the pattern 14 is provided from the washing place 4a to the pontoon 10, the presence of the pontoon 10 is not conspicuous, and the washing place 4a can be seen widely. Further, when the pattern 14A is formed in a convex shape, there is also an anti-slip effect.

[Another Embodiment] Another embodiment will be described below. The sectional shape of the drainage channel 5 may be configured as shown in FIG. In other words, in order to increase the groove bottom lateral width L toward the downstream side, a symmetrical configuration may be adopted in which the groove bottom lateral width L is widened from the center of the left and right lateral widths. On the upstream side, the narrow part of the groove width is located at the center position of the groove width, so that cleaning can be easily performed by inserting a cleaning tool. As a cross-sectional shape of the drainage channel 5, as shown in FIG. 16, the side wall 5 </ b> B on the washing station 4 a side may be formed as an introduction inclined surface 5 </ b> E inclined toward the washing station over the entire length of the drainage channel 5.
This makes it easier for the washing water from the washing place 4a to flow into the groove bottom 5C without dividing even if the amount of water is small in the part between the washing place 4a and the upper end opening of the drainage channel 5. As shown in FIG. 16, the groove bottom 5C of the drainage channel 5 may be configured to be inclined toward the bathtub side wall 5D located at one end in the width direction. Thus, it is possible to collect the washing water at the corner of the side wall 5A on the bathtub side and flow it without being divided, even if the amount of water is small, while taking the width L of the groove bottom 5C wide. As for the height of the side walls 5A and 5B of the drainage channel 5, that is, the depth of the drainage channel 5, the downstream side may be made deeper. Although various structures of the drainage channels 5 and 6 have been described above, the drainage grooves 4b and 4b have the same function as a structure for guiding washing water to the drainage port 11 and the like. The invention and the invention of another embodiment may be applied.
