Abstract

PURPOSE:To prevent a storage space from being influenced by water even when the water infiltrates into a cabinet. CONSTITUTION:A recessed groove 13 of specified depth is formed at the counter upper face 12 in line with the peripheral edge of a slotted hole formed at a counter, and a draining protrusion 15 of almost trapezoidal cross section is formed at the counter lower face in line with the peripheral edge, over the whole periphery. When water falling on the counter and getting into the recessed groove 13 is a small quantity, the water is naturally evaporated in the recessed groove 13, and even when the water is a large quantity so as to overflow out of the recessed groove 13, the water does not flow over the protrusion 15 but falls from the end part 16.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet bowl unit with a hand basin.

[0002]

2. Description of the Related Art A low tank or a water supply pipe section is provided in a cabinet formed in the rear part of a toilet bowl, and a counter hole on the upper surface of the cabinet is provided with a cut hole to which a hand-washing device is fitted.

FIG. 8 is a plan view of a toilet room equipped with a conventional toilet bowl unit with a toilet bowl. A cabinet 101 is arranged inside the toilet room 100. A hand washing device 105 having a water faucet 104 is arranged in a cut hole 103 formed in a central portion of a counter 102 which constitutes an upper surface of the cabinet 101. Spaces 106a and 106b for storing articles are defined in the left and right portions of the cabinet 101 with the hand wash device 105 interposed therebetween. The rear part of the toilet bowl 107 is brought into contact with the front surface of the cabinet 101, and the front part of the toilet bowl faces the center of the toilet room 100.

FIG. 9 is a side view of a toilet room equipped with a conventional toilet bowl unit with a toilet bowl. The cabinet 101
A water supply pipe 108 and the like connected to the water faucet 104 are stored therein. Above the water supply pipe 108 and the handwasher 105
A low tank 109 that stores the cleaning water and has an open upper side is provided below. Then, the toilet user operates the operating lever 110 on the front surface of the low tank 109 to supply the flush water to the toilet bowl 107.
The cut hole 103 (see FIG. 8) is used for the low tank 10.
9 also serves as an inspection hole.

FIGS. 10 (a) and 10 (b) show 10-10 of FIG.
10A is a sectional view taken along the line, FIG. 10A shows an example in which the peripheral edge of the hand washing device 105 is placed on the counter 102 via the packing 111, and FIG. 10B shows a step on the peripheral edge of the cut hole 103 of the counter 102. An example is shown in which the portion 112 is formed, and the peripheral edge of the hand washing device 105 is placed and fitted on the step portion 112 via the packing 111.

[0006]

In the structure described above, the packing is crimped to prevent a gap from being formed between the handwasher and the counter, but the packing is peeled off or the crimping is performed by placing the handwasher on the counter. With just that, the crimping would be insufficient and a gap would be created between the packing and water, and water might have entered the cabinet.

The water that has entered the cabinet flows to the left and right along the lower surface of the counter, and not only below the handwasher, but also in the space 106a formed for storing the articles.
There is a problem in that 106b is wet or damp.

The present invention has been made to solve the above problems, and its purpose is to prevent the storage space from being affected by water even when water enters the cabinet. is there.

[0009]

In order to solve the above problems, a toilet bowl unit with a hand basin according to claim 1 of the present invention comprises:
At the periphery of the cut hole formed in the counter, a concave groove for receiving the peripheral portion of the hand washing device was formed on the upper surface, and a convex strip for draining water was formed on the lower surface.

In the toilet bowl unit with a hand basin according to a second aspect, a concave groove for receiving the peripheral edge of the hand basin is formed on the upper surface of the cut hole formed in the counter, and a groove for draining water is formed on the lower surface. did.

A recessed groove 13 having a predetermined depth is formed on the counter 10. When the handwasher 1 is fitted into the cut hole 11 by engaging the peripheral edge portion 2 of the handwasher 1 with the recessed groove 13, The upper surface 12 and the upper surface 5 of the handwasher 1 are substantially flush with each other so that the counter 10 and the handwasher 1 have a sense of unity.

On the other hand, on the lower surface 14 of the counter 10 which is continuous with the peripheral edge, the upper end of the opening portion of the low tank 109 in which the protrusion 15 for draining water having a substantially trapezoidal cross section is widened upward along the entire circumference. It is formed so as to be located inside the edge.

The operation of the toilet bowl unit with a hand basin according to the first embodiment having the above-described structure is performed by the hand basin 1 and the counter 10.
The handwasher 1 and the counter 10 are configured as described above. Therefore, when the toilet user operates the operation lever 110 to discharge the waste in the toilet bowl 107, Even if the supplied water splashes from the handwasher 1 by splashing in the bowl-shaped portion due to hand washing or the like and flows into the concave groove 13, if the amount of water flowing into the concave groove 13 is small, the time elapses. Along with this, it is naturally evaporated and does not flow to the lower surface 14 of the counter 10.

The washing water spilling from the hand washing device 1 is recessed 13
When the amount of water is too large to enter, the water overflows from the groove 13, but even at this time
5 flow through the surface 5 and from its end 16 to the low tank 109
Dripping inward, over the ridge 15 and further counter 10
Does not flow along the lower surface 14 of the.

FIG. 2 shows a modification of the water draining portion in FIG. 1, which is the lower surface 1 of the counter 10 which is continuous with the peripheral edge of the cut hole 11.
4 has a groove 17 for draining, for example, having a substantially trapezoidal cross section, and the lower surface 14 so that its peripheral portion is located inside the upper end edge of the opening of the low tank 109 (see FIG. 1). The groove 17 is formed by shaving, and the groove 17 has substantially the same structure as the ridge. Therefore, since the same operation as that of the first embodiment is achieved, the description thereof will be omitted.

The toilet bowl unit with a hand basin of the second embodiment is also the toilet bowl 107 described in FIG. 8 and this toilet bowl 107.
