When storing the lid after completion of washing or bathing in the bathtub 1 after filling with hot water, the lid of the bathtub 1 is opened by folding the lid plate 2 using the folding groove 6 as shown in FIG. And storage of the lid.

In this embodiment, one end of the cover plate 2 is fixed to the upper edge wet edge 7 of the bathtub 1, so that the hose of the inflow line 13 does not need to be removed after washing is completed. It is very convenient because it does not take up the available space and get in the way.

FIG. 3 shows a second embodiment of the cleaning tub lid relating to the hose. In the second embodiment, a supply passage 11a for detergent and a supply passage 11b for washing water are separately formed inside the cover plate 2, and a common ejection portion 12 is provided at the tip side of the supply passages 11a and 11b. (Of course, the ejection part 12 is connected to each supply passage 11a,
It can be provided separately at the tip of 11b. ). In the supply passages 11a and 11b located in the vicinity of the ejection part 12, check valves 18a and 18b as on-off valves are provided in a state buried in the cover plate 2. A detergent-side base passage communicating with the detergent supply passage 11a is connected to the detergent supply source 5 through an inflow conduit 13a such as a hose, and is connected to the detergent water supply passage 11b. Similarly, the end side passage 13

FIGS. 4 and 5 show a third embodiment of the cleaning tub lid according to the present invention. The difference between the third embodiment and the above-mentioned embodiments is that the cover plate 2 of the bathtub 1 is formed in a sheet-like body, and is wound up and stored by a winding shaft 20 provided at one end of the bathtub 1. It was done. The base end of the sheet-shaped cover plate 2 is fixed to a take-up shaft 20, and the forward / reverse rotation of the take-up shaft 20 allows the cover plate 2 to be pulled out to the upper surface of the bathtub opening and to the take-up shaft 20 side. Can be taken up and stored freely.

As the rotation drive source of the winding shaft 20, for example, a full dance or a coil spring is used, and when the cover plate 2 is pulled out, it is pulled out against the restoring force of the full dance or the restoring force due to the torsional rotation of the coil spring. By fastening the engaging hole 21 provided on the tip side of the cover plate 2 to the hook 22 on the bathtub 1 side, the cover plate 2 can be closed in a tight state, and when the cover plate 2 is opened. When the engaging hole 21 is removed from the hook 22, the cover plate 2 can be automatically wound up and stored by the winding shaft 20 by the full rotation or the restoring rotational force of the coil spring.

A supply passage 11 for the detergent and the washing water is formed inside the cover plate 2 of the sheet-like body in the same manner as in the first embodiment, and a jet portion 12 is provided at the tip end of the supply passage 11. Supply passage
The base side passage of 11 is a three-way valve through an inflow line 13 such as a hose.
Connected to 14.

In the third embodiment, the inflow conduit 13 such as a hose needs to be removed when the lid 2 is stored because the lid plate 2 is wound around the winding shaft 20 and stored. As compared with the conventional apparatus of FIG. 6, the hose can shorten the supply passage 11 and the removed hose 13 is not so bulky, so that the hose can be leaned against a narrow dead space between the bathtub 1 and the bathroom wall. So you can hardly get in the way.

The present invention is not limited to the above embodiment,
Various embodiments may be employed. For example, the cover plate 2 is a bathtub 1
May be configured so as to be removable with respect to. In this case, the supply passages 11, 11a, 1 formed inside the cover plate 2
The hoses 13, 13a and 13b for connection between 1b and the detergent supply source 5 or the washing water supply source are removed when the cover plate 2 is removed or after the bathtub 1 is completely washed. Since the supply passage is formed in the plate 2, the length of the hose can be shortened accordingly, the removed hose does not become bulky, and the removed hose takes up an effective space in the bathroom and becomes an obstacle. It is rare.

Further, in the second embodiment, the detergent supply passage 11a is provided.
Although the check valves 18a and 18b are provided in the supply passage 11b for the washing water, the check valve 18b on the washing water side can be omitted.
Further, the check valve does not necessarily need to be provided near the ejection section 12, but can be provided at an arbitrary position in the supply passage. However, as in the present embodiment, if the cleaning agent is provided in the vicinity of the ejection portion 12, the amount of the detergent that flows out after the completion of the washing and is wasted can be reduced, and the detergent can be further saved. The check valve may, of course, be provided in the supply passage 11 shown in the first embodiment.

Further, in the embodiment, the on-off valve is constituted by the check valve,
As long as it has a function of opening and closing the flow path, it can be configured using any other valve such as a solenoid valve.

[Effect of the invention]

In the present invention, a supply passage for supplying detergent and cleaning water is provided in the cover plate of the bathtub, and a jetting portion is provided at the tip thereof, so that a hose is directly used from the supply source of detergent and cleaning water to the jetting portion. The length of the hose can be reduced by the amount of the supply passage provided in the lid plate as compared with the conventional example in which the hose is removed, even if the hose is removed and leaned against the bathroom. The hose is not bulky and can be stored, for example, by utilizing the narrow dead space between the bathtub and the bathroom wall, so that the bulky hose does not take up the effective space in the bathroom and obstruct it as in the conventional case. Further, in a configuration in which a plurality of supply passages for the detergent and the washing water are provided at intervals, and a jetting portion is provided at the tip of each supply passage, the detergent and the washing water are provided from a plurality of different positions in the width direction of the lid plate. Can be uniformly sprayed onto the inner surface of the bathtub, and one supply passage is formed with one blowout portion at the tip end thereof.
Since a plurality of ejection parts are not provided on one supply passage), the detergent and the washing water can be ejected from each ejection part vigorously, and the effect of washing the bathtub can be sufficiently enhanced.

Further, since the washing tub lid of the present invention is formed of a single piece, it is possible to form a supply passage for the detergent and washing water in the lid plate by a continuous hole passage from the inlet to the outlet. As described above, by forming the supply passages by the hole passages, a hand gap for inserting the passage forming pipe into the inside of the cover plate is not required, so that the manufacturing workability of the washing tub cover can be improved and the cost can be reduced.

Furthermore, in the configuration in which the supply passage for the detergent and the supply passage for the washing water are separately provided inside the lid plate, after the bath tub is washed by using the detergent, when the detergent or the like on the inner surface of the bath tub is washed by the washing water. Since the washing water is not supplied to the supply passage for the detergent, the detergent remains in the supply passage for the detergent as it is and is effectively used for washing with the next detergent. Detergent can be saved, and significant cost savings can be achieved.

Further, in a configuration in which the tip of the supply passage for the detergent and the supply passage for the washing water are merged, and a common ejection portion for the detergent and the washing water is provided at the junction, each supply passage is provided. Therefore, the number of ejection parts can be reduced as compared with the case where an ejection part is provided, so that the configuration can be simplified and the cost can be reduced. Even in the case where the ejection part is shared in this manner, the on-off valve is provided in the detergent supply passage, so that the detergent remaining in the detergent supply passage during washing with the washing water can be prevented from flowing out, and the detergent can be prevented. Can be effectively used without waste.
In addition, since the on-off valve is installed buried in the lid plate,
This is convenient because it does not hinder the handling of the cover plate.
