Abstract

PROBLEM TO BE SOLVED: To wash a large object and to use remaining hot water in a bathtub by providing a recessed part at the bottom of the bathtub and rotatably connecting a mixing blade to the axis body of a driving device at the rear side of the recessed part whose cap is freely attachable and detachable. SOLUTION: The cap 15 is additionally provided in the state of being freely attachable and detachable at the recessed part 13 at the bottom 12 of the bathtub 10 opening its top face and formed by side walls of its four sides and the bottom 12. At the time of normal bathing, it is used as a bathtub in the state of covering the recessed part 13 with the cap 15. This cap 15 is necessitated to make a flat bottom 12 without a recess/projection for the safety of a bathing person. The driving device 16 is installed on the rear side of the part 13 and the axis body 16a of this driving device 16 penetrates the bottom of the part 13. A rotary blade 14 is pivotally fitted to the axis body 16a and rotated by being pivotally fitted to the axis body 16a of the driving device 16 penetrating the bottom. At the time of using as a washing tank, the cap 15 is removed while keeping the remaining hot water as it is and the blades 14 are rotate- driven to wash a large matter, such as a carpet, blanket, etc., to reduce labor and to improve economy.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a bathtub having a washing function.

[0002]

2. Description of the Related Art Conventionally, in a bathtub installed and used in a bathroom of a general house or the like, the remaining hot water after use is pumped and transferred to a washing tub of a washing machine, and is effectively used for washing clothes and the like. Have been. Such reuse of the remaining hot water in the bathtub is very significant in terms of energy saving and economic efficiency in home life.

[0003]

However, when using the remaining hot water in the bathtub, the remaining hot water must be transported to the washing machine many times using a bucket or the like unless a special pump or the like is used. For housewives, etc.
There was a problem that it often required considerable hard work. On the other hand, in recent years, large-capacity washing machines have also been developed, and it is possible to wash some rugs and blankets that are large and bulky. Is difficult to wash.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to solve these problems and to provide a rug or a rug, in addition to small-sized objects. An object of the present invention is to provide a bathtub having a washing machine function capable of washing large items such as blankets and using the remaining hot water in the bathtub as it is, reducing labor and improving economic efficiency. .

A bath tub according to the present invention is a bath tub having an upper surface opened and formed by four side walls and a bottom, wherein the bottom is provided with a recess, and the recess is provided with stirring. The wing is rotatably connected to a shaft of a driving device provided on the back side of the recess, and a lid is detachably provided in the recess.

[0006] The material and molding of the bathtub are the same as those of the conventional FRP.
, Stainless steel or the like can be used, and the concave portion can be formed at the same time and provided integrally.

[0007] The recess is preferably provided at the bottom of the bathtub at a location where the hot water agitation efficiency is highest, that is, substantially at the center. In addition, when used as a normal bathtub, a lid is provided on the upper surface of the concave portion, which is necessary for providing a flat bottom without unevenness for the safety of bathers.

[0008] The stirring blade is rotatably mounted on a shaft of a driving device penetrating through the bottom of the recess.
The drive device for rotating the stirring blades may be mounted on a low-speed motor capable of obtaining a predetermined number of rotations, or a shaft body in which a conventional AC motor is reduced to a predetermined number of rotations by a reduction mechanism.

[0009] It is necessary that the through-hole of the shaft body of the concave portion be reliably waterproofed by a sealing mechanism. This waterproofing of the shaft body can be realized by a conventional technique.

[0010] The operation of the drive device when used as a washing machine can be easily performed by providing an ON / OFFC switch separately in the bathroom. Automatic operation can be performed by connecting to a timer. It is also possible to

[0011]

In the bathtub of the present invention, the bathtub has an upper surface opened and is formed by four side walls and a bottom portion.
A recess is provided in the bottom, and a stirring blade is rotatably connected to a shaft of a driving device provided on the back side of the recess, and a lid is detachably provided in the recess. So, for normal bathing, use the concave part as a bathtub with the lid covered with a lid, when using as a washing tub, leave the remaining hot water in the bathtub as it is, remove the lid,
By rotating and driving the stirring blade, large items such as rugs and blankets can be washed, labor can be reduced, and economy can be improved.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective sectional view showing an example of the bathtub of the present invention. In FIG. 1, a bathtub 1 of the present embodiment is shown.
The reference numeral 0 denotes an open upper surface, which is formed by four side walls 11 and a bottom 12. Almost at the center of the bottom 12,
A recess 13 is provided, and a stirring blade 14 is rotatably connected to a driving device 15 provided on the back side of the recess 13 in the recess 13. That is, the concave portion 13 is provided at a location where the stirring efficiency of hot water is the best at the bottom of the bathtub, that is, at a substantially central portion in consideration of the shape of the bottom portion 12 of the bathtub 10.

Further, in the recess 13 of the bottom portion 12, a lid 15 is separately provided detachably.
When used as a normal bathtub, the lid 15 is necessary for forming a flat bottom 12 without unevenness for the safety of bathers. The lid 15 is fitted into a fitting groove 13 a having an L-shaped cross section at the periphery of the recess 13.
2 so as to be fitted almost flush with the upper surface thereof.

As the material of the bathtub 10, conventional FRP, stainless steel or the like can be used. In this embodiment,
The bathtub 10 is formed by simultaneously forming the concave portion 13 integrally using FRP.

A driving device 16 is provided behind the recess 13, and a shaft 16 a of the driving device 16 is
Of the rotating blade 14
Is attached to the shaft. The drive device 16 is rotatably mounted on a shaft 16a penetrating the bottom. The penetrating portion of the shaft 16a of the concave portion 13 is reliably waterproofed by the seal mechanism 16b.

A driving device 16 for rotating the stirring blade 14 includes:
A low-speed motor capable of obtaining a predetermined number of rotations or a conventional AC motor whose speed is reduced to a predetermined number of rotations by a reduction mechanism is preferably used.

Driving device 1 when used as a washing machine
