Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention provides a technique in which a bulky laundry that cannot be washed by a domestic washing machine is washed using a bathtub and can be dehydrated after washing.

[0002]

[Prior art]

 It is very difficult to wash bulky textiles such as blankets and beds in electric washing machines for general household use. Therefore, it is possible to use the bathtub as a washing tub to wash the above-mentioned bulky laundry.

[0003]

[Problems to be solved by the device]

 However, when washing in a bathtub, it is necessary to manually stir the inside of the bathtub because a means for stirring the laundry is not usually provided. Furthermore, no measures have been taken for dehydration after washing.

[0004]

[Means for Solving the Problems]

 The present invention provides a means for not only washing but also dehydration after washing using a bathtub. The features of the bathtub according to the present invention include a pump for sucking hot water from the bathtub and ejecting the hotwater into the bathtub, and a passage switching valve provided in the middle of the drain pipe connected to the drain port of the bathtub. And a connecting pipe connected to the switching valve to connect the drain pipe and the inflow side of the pump, and a water storage bag detachably attached to the hot water jet outlet provided in the bathtub. Is.

[0005]

[Action]

 When the bathtub according to the present invention is used as a washing tub, hot water or water is stored in the bathtub, and then a pump is operated to agitate the hot water sucked from the bathtub into the bathtub to stir the laundry. Do the laundry.

After the washing is finished, in order to dehydrate the laundry, the water storage bag is connected to the jet port provided in the bathtub, and the switching valve provided in the middle of the drain pipe is operated to operate the drain pipe and the pump. It is configured to communicate with the inflow side through a communication pipe. Therefore, by operating the pump, the hot water in the bathtub is sucked from the drain pipe through the connecting pipe, and then sent from the ejection port into the water storage bag. Therefore, by placing this water storage bag on the washed laundry, the weight of the water storage bag can be pressed to dehydrate the laundry.

【Example】

 FIG. 1 schematically shows the configuration of an embodiment of a bathtub A with a washing / dewatering function according to the present invention (hereinafter, referred to as "main bathtub"). Explaining the configuration of the proposed bathtub A, the bathtub 1 is provided with a pump 2 that sucks hot water from the bathtub 1 and ejects the hotwater into the bathtub 1. The outflow side of the pump 2 and the bathtub 1 are connected by a jet pipe 3. The inflow side of the pump 2 and the bath tank 1 are connected by a suction pipe 4. The ejection port 3a of the ejection pipe 3 is opened slightly above the bath inner surface 1a, while the suction port 4a of the suction pipe 4 is opened slightly below the bath inner surface 1a. A drainage pipe 6 is connected to a drainage port 5 provided on the bottom surface of the bathtub 1, and the middle of the drainage pipe 6 and the middle of the suction pipe 4 are connected by a communication pipe 7. In addition, switching valves 8 and 9 are provided at the connecting portion between the drainage pipe 6 and the connecting pipe 7 and at the connecting portion between the suction pipe 4 and the connecting pipe 7, respectively, so that the flow paths can be switched.

To wash using the bathtub A of the present invention configured as described above, as shown in FIG. 2, after hot water or water is stored in the bathtub 1, the pump 2 is operated to operate from the suction port 4a. The hot and cold water that has been sucked is ejected from the ejection port 3a into the bathtub 1 to stir the hot and cold water in the bathtub 1 to wash the laundry 10. Since the capacity of the bathtub 1 is much larger than the capacity of the washing tub of the domestic washing machine, even a very bulky item such as a blanket or a bed sheet can be easily washed. By appropriately setting the positions and the number of the jet nozzles 3a, it is possible to generate a desired water flow state such as a vortex flow. Further, it is optional to use the remaining hot water as hot water for rinsing.

After washing and rinsing by the same method as necessary, the laundry is drained. First, as shown in FIG. 3, the jet port 3a of the bathtub 1 and the water storage bag 20 are connected by a flexible hose 21, and the switching valves 8 and 8 provided on the drain pipe 6 and the suction pipe 4, respectively. 9 is operated to form a flow path in which hot and cold water in the bathtub 1 flowing out from the drainage port 5 is sucked into the pump 2 through the drainage pipe 6 and the communication pipe 7. Therefore, by operating the pump 2, the hot and cold water in the bathtub 1 is sucked into the pump 2 from the drain port 5 via the drain pipe 6, the connecting pipe 7 and the suction pipe 4, and then the jet pipe 3 and It is fed into the water storage bag 20 through the hose 21. Therefore, by placing the washed laundry 10 in a desired form on the bottom surface 1b of the bathtub 1 and placing the water storage bag 20 on it through the pressing plate 22 or the like, the water storage bag in which hot water is stored is stored. The weight of 20 causes the laundry 10 to be pressurized and dehydrated.

If the weight of the water storage bag 20 is not sufficient for draining the laundry 10 from the water in the bathtub 1 only, the water may be replenished from the faucet or the like into the bathtub 1. Since the water is fed into the water storage bag 20 through the drainage port 5, the weight of the water storage bag 20 can be increased.

The water storage bag 20 is a bag made of synthetic resin or the like, and its shape is determined according to the shape, size, etc. of the bathtub 1. Further, the pressing plate 22 for causing the weight of the water storage bag 20 to uniformly act on the laundry 10 may be integrated with the water storage bag 20.

FIG. 4 shows another embodiment of the bathtub A of the present invention. The difference from this embodiment is that the connecting pipe 7 connected to the drainage pipe 6 via the switching valve 8 also serves as the suction pipe 4 of the pump 2, and the hot and cold water in the bathtub 1 is circulated. The point is to use the drainage port 5 as a suction port when it is ejected. In this embodiment, since the flow paths are the same during washing and dehydration, it is not necessary to operate the switching valve 8 when shifting from the washing process to the dehydration process. The procedures for washing and dehydrating are the same as those in the above-mentioned embodiment, and the description thereof is omitted here.

It is to be noted that the objects to be washed and dehydrated in the bathtub of the present invention may have a three-dimensional shape such as a large plush toy, in addition to a blanket and a floor cloth. In addition, the embodiments of the present invention do not prevent appropriate modifications depending on the situation, in addition to those described above.

[0014]

[Effect of device]

 The proposed tub can be washed using the tub, and can be dehydrated after washing with a water storage bag. Therefore, it is possible to wash and dehydrate bulky laundry, which was impossible with a conventional washing machine. .
