DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub device capable of discharging hot water toward a bather's shoulder or the like.

[0002]

2. Description of the Related Art Conventionally, a blow operation for blowing bath water into a bathtub body and a discharge blow operation (so-called shoulder blow operation) for discharging bathwater from above the bath surface to the inside of the bathtub body can be performed simultaneously. As a bathtub device,
For example, there is one described in Japanese Utility Model Laid-Open No. 2-30639.

[0003] In such a bathtub apparatus, a bathwater circulation flow path comprising a water absorption pipe and a water supply pipe is interposed between the bathtub body and a circulation pump so that the bathwater can be jetted into the bathtub body. The base end of the water discharge pipe whose upper end discharge port is located above the inside of the bathtub body is connected to the water supply pipe through a switching valve.

In this way, by operating the switching valve, one or both of the blow operation and the discharge blow operation can be performed.

[0005]

However, in the case of the above-mentioned bathtub apparatus, when the switching valve is operated during the blow operation, the amount and pressure of the spout of the bath water changes, and the feeling of blow of the bather changes. There is a problem that bathers enjoying bathing feel uncomfortable.

[0006] In particular, during the discharge blow operation, there is a problem that a switching valve attached to the water discharge pipe causes a pressure loss or the like, so that a sufficient discharge pressure cannot be obtained and a massage effect is low.

Further, the bath water discharged from the discharge port is used by circulating the bath water in the bathtub body through a water absorption pipe and a water discharge pipe by a circulation pump. When the hot water is discharged from the discharge port and directly hits the bather's face or the like, there is a problem that the bather is uncomfortable.

[0008]

Therefore, according to the present invention, a bath water circulation path comprising a water absorption pipe and a water supply pipe is interposed between the bathtub body and the circulation pump, so that the water absorption pipe is provided from inside the bathtub body. In the bathtub device, the hot water sucked through can be jetted into the bathtub body through the water supply pipe, and the tip of the water suction pipe is connected to the lower impeller chamber of the circulation pump composed of the multi-stage impeller type pump, and the lower impeller chamber is connected to the lower impeller chamber. Communicating and connecting the base end of the water supply pipe to enable circulation of bath water,
In addition, the tip discharge port is located above the water surface in the bathtub body, and the base end of a water discharge pipe provided with a filter in the middle thereof is connected to the upper impeller chamber of the circulating pump so as to communicate with the filter. The hot water filtered by the filter can be discharged from the tip water outlet into the bathtub body, and a switching means is interposed in the water discharge pipe on the downstream side of the filter, and the water discharge pipe and water supply pipe are connected by the filtration / backwashing pipe. It is intended to provide a bathtub device characterized by communication.

The present invention also has the following configuration.

A flow path control means is provided between the water supply pipe and the water discharge pipe. The flow path control means blows the hot water into the bathtub body through the water supply pipe, and discharges the hot water through the water discharge pipe. Simultaneous operation of discharge blow operation discharging from the outlet or any one of them can be operated independently.

[0011] The switching means is a second three-way valve, and a first three-way valve in which a drain pipe is connected to a water discharge pipe on the upstream side of the filter F is interposed to enable the filter to be backwashed. That, furthermore, form a branch pipe on the tip side of the water supply pipe,
The distal end of the branch pipe is connected to each of the side walls on the foot side and the back side of the bathtub body, and the first and second on-off valves are attached to the respective branch pipes to switch the first and second three-way valves. First
-The following operations can be performed by combining the opening and closing operations of the second on-off valve.

A blow operation in which bath water is blown into the bathtub body from at least one of the foot side and the back side.

A discharge blow operation for discharging bath water from the discharge port at the tip.

[0014] Filtration operation for filtering bath water by a filtration machine during the blow operation.

Simultaneous operation of blow operation and discharge blow operation.

A backwashing operation in which the bath water flows back through the filter to wash the filter.

[0017]

[Function] The blow operation for blowing out the bath water into the bathtub body is as follows.
By operating the circulation pump, the bath water in the bathtub main body can be sucked in through the water-absorbing pipe, and can be discharged into the bathtub main body through the water-supplying pipe.

The discharge blow operation for discharging the bath water from the tip discharge port is also performed by operating the circulation pump.
While inhaling the bath water in the bathtub through the water absorption pipe,
Discharge into the bathtub body from the tip discharge port through the water discharge pipe, for example, toward the bather's shoulder (so-called shoulder blow)
Can be done.

At this time, the circulation pump uses a multi-stage impeller type pump, and the leading end of the water absorption pipe and the base end of the water supply pipe are connected to the lower impeller chamber of the circulation pump, respectively. Since the base end of the water discharge pipe is connected and connected, the pressure of the pressurized bath water can be increased in the lower impeller chamber and the pressure of the bath water can be further increased in the upper impeller chamber. Discharge can be performed from the distal end discharge port, so that the blow feeling can be kept constant even when the operation is changed, and the bather enjoying the blow bath does not feel uncomfortable.

In addition, a sufficient massage effect to the bather's shoulder and the like by the discharge blow operation can be obtained.

In addition, even when a filter is attached to the water discharge pipe and clear bath water filtered by the filter is always discharged from the distal end discharge port even when the filter is used for a long time, the water discharge is directly performed on the face of the bather. In this case, it is possible to prevent the bather from feeling uncomfortable, and to provide a comfortable bath.

A flow path control means is provided between the water supply pipe and the water discharge pipe. The flow path control means blows the hot water into the bathtub body through the water supply pipe, and discharges the hot water through the water discharge pipe 7. Simultaneous operation of the discharge blow operation discharged from the discharge port or any one of the independent operations is enabled, and blow according to a bather's preference can be provided.

More specifically, a drain pipe is connected to a portion of the water discharge pipe located between the circulation pump and the filter through a first three-way valve, and the water discharge pipe is located downstream of the filter installation position. One side is connected to the filtration and
The other end of the backwash pipe is connected through a second three-way valve to form a branch pipe at the end of the water supply pipe, and the ends of the branch pipe are respectively connected to the foot side and the back side of the bathtub body. The first and second on-off valves are attached to each branch pipe, and the combination of the switching operation of the first and second three-way valves and the on-off operation of the first and second on-off valves allows the back side of the bathtub body to be connected. In addition to the blow operation for jetting bath water from at least one of the feet and the blow operation, the discharge blow operation and the filtration operation, a backwash operation for backflowing the bath water to the filter to wash the filter can be performed. The filter can be normally operated by the washing operation, the bath water can be surely filtered by the filter, and a comfortable blow bath can always be provided by clear water discharge.
