Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub device.

0002

[Prior Art] Conventionally, it has been possible to simultaneously perform a blow operation in which bath water is jetted into the bathtub body and a discharge blow operation (massage blow operation) in which bath water is discharged from above the water surface into the bathtub body. As a bathtub device, for example,
There is one described in Utility Model Application Publication No. Hei 2-130639.

[0003] Such a bathtub device has a bathwater circulation flow path consisting of a water suction pipe and a water supply pipe interposed between the bathtub body and the circulation pump, so that bathwater can be spouted into the bathtub body, and A base end of a water discharge pipe whose distal end outlet is located above the interior of the bathtub body is connected to the water supply pipe via a switching valve.

[0004] In this way, by operating the switching valve, one or both of the blowing operation and the discharge blowing operation can be performed.

[0005]

[Problems to be Solved by the Invention] However, in the case of the bathtub device described above, if the switching valve is operated during blowing operation, the amount and pressure of the hot water jetted change, and the blowing sensation for the bather changes. There is a problem in that it gives a feeling of discomfort to bathers who are enjoying bathing.

In addition, since the bath water discharged from the outlet is used by circulating the bath water inside the bathtub body through the water suction piping and water discharge piping using a circulation pump, it is difficult to remove the bath water that has become dirty due to long-term use. There is also the problem that if hot water is discharged from the outlet and directly hits the bather's face, the bather will feel uncomfortable.

[0007]

[Means for Solving the Problems] Therefore, in the present invention, a bath water circulation flow path consisting of a water suction pipe and a water supply pipe is interposed between the bathtub body and the blow circulation pump, and In a bathtub device that can spout bath water, the water absorption piping is
The base end of the water discharge pipe whose tip discharge port is located above the water level in the bathtub body is connected for communication, a circulation pump for discharge blowing is attached to the water discharge pipe, and a filter is attached to the water discharge pipe, It is an object of the present invention to provide a bathtub device characterized in that bath water filtered by the filter is discharged from a distal end outlet.

The present invention is also characterized by the following configuration.

[0009] A drain pipe is connected to a portion of the water discharging piping located between the discharge blow circulation pump and the filter via the first three-way valve, and a portion of the water discharging piping located downstream of the filter mounting position In addition, one end of the filtration system is connected to the water pipe.
The other end of the backwash piping is connected through a second three-way valve,
By the combination of the switching directions of the first three-way valve and the second three-way valve,
The following operations have been made possible.

[0010] ■Blow operation that squirts bath water into the bathtub body.

■Discharge blow operation in which bath water is discharged from the tip discharge port.

(2) Filtration operation in which bath water is filtered by a filter during blowing operation.

■ Simultaneous operation of blow operation and discharge blow operation.

[0014] ■ Backwash operation in which the filter is washed by flowing bath water back into the filter.

[0015] One end of a fume piping is connected to the bottom of the bathtub body, and a compressor is attached to the fume piping, so that air can be blown out from the bottom of the bathtub body.

[0016] An oxygen enrichment membrane device is attached to the fumarole piping, so that air whose oxygen content has been increased by the oxygen enrichment membrane device can be blown out from the bottom of the bathtub body.

[0017] The pump driving motor of at least one of the blow circulation pump and the discharge blow circulation pump can be controlled by an inverter.

[0018]

[Operation] Blow operation that squirts bath water into the bathtub body is
By operating the blow circulation pump, bath water in the bathtub body can be sucked through the water suction piping and can be jetted into the bathtub body through the water supply piping.

In addition, in the discharge blow operation in which bath water is discharged from the tip discharge port, by operating the discharge blow circulation pump, the bath water inside the bathtub body is sucked through the water suction pipe, and at the same time, the bath water is sucked into the bath water from the tip discharge port through the water discharge pipe. The liquid can be discharged into the bathtub body, for example, toward the shoulders of the bather (so-called shoulder blow).

[0020] At this time, the blow operation and discharge blow operation are
Since a dedicated circulation pump is used for each bath, the blow feeling can be kept constant even when the operation is changed, and bathers who are enjoying blow bathing will not feel uncomfortable.

[0021] A filter is attached to the water spouting pipe, and even during long-term use, clear bath water filtered by the filter is always discharged from the tip outlet, so that the water is directly sprayed onto the bather's face, etc. Even in the case of contact, it is possible to prevent the bather from feeling uncomfortable and provide a comfortable bathing experience.

[0022] A drain pipe is connected to a portion of the water discharging piping located between the discharge blow circulation pump and the filter via the first three-way valve, and a portion of the water discharging piping located downstream of the filter mounting position In addition, one end of the filtration system is connected to the water pipe.
The other end of the backwash piping is connected through a second three-way valve,
By combining the switching directions of the first three-way valve and the second three-way valve, in addition to the blow operation, discharge blow operation, and filtration operation described above, a backwash operation is performed in which bath water flows back into the filter to clean the filter. This backwashing operation allows the filter to function properly and reliably filters the bath water.
It is possible to provide a comfortable blow bath with always clear water discharge.

[0023] One end of the fume piping is connected to the bottom of the bathtub body, and a compressor is attached to the fume piping so that air can be blown out from the bottom of the bathtub body, in addition to the blow operation and discharge blow operation described above. The bather can also perform a steam operation, and the bather can select and use each operation according to his/her preference.

[0024] At this time, by attaching an oxygen enrichment membrane device to the fumarole piping and making it possible to blow out air with increased oxygen content from the bottom of the bathtub body by the oxygen enrichment membrane device,
It can enhance the refreshing effect of bathers, such as recovering from fatigue and relieving stress.

[0025] By making the pump drive motor of at least one of the blow circulation pump and the discharge blow circulation pump controllable by an inverter, the rotation speed of the pump can be smoothly changed, and the discharge pressure and discharge of bath water can be adjusted. The amount can be changed steplessly to provide bathers with varying blowouts.
