Abstract

PURPOSE:To secure a higher filtering capacity while operation in filtering can be recognized simply and clearly by turning an air control valve to a opening position while a reflux water control valve to one jet nozzle is turned to an opening position when a quick filtering mode is specified. CONSTITUTION:When a quick filtering mode is set, a sequence control shifts an air control valve 4 and one reflux water control valve 9a to an opening position while the other reflux water control valve 9b is turned to a closing position. The air control valve 6 is opened fully, the reflux water control valve 9a is turned to an interrupted opening and the reflux water control valve 9b is closed fully. There is no spouting of a jet flow from a jet nozzle 3b on the opposite side to a suction port 2. A jet flow Ja spouted from a jet nozzle 3a on the side where the suction port 2 exists reaches a side wall on the opposite side to the suction port 2 from a central part of a bath tub 1 and detours here to cause a large convection Wc extending to the suction port 2 passing the underside of the central part of the bath tub 1 by water W0 in the bath tub. Thus, contamination of the water W0 in the bath tub can be taken out of the suction port 2 efficiently to undergo a filter processing.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention involves sucking the water in the bathtub from the bathtub, mixing air into it, and injecting a jet stream for foam pine surge from the side of the bathtub into the water in the bathtub. The present invention relates to a bathtub system configured as follows.

<Prior Art> Conventionally, as a special function in a bathtub system, there is a jet mode in which a jet stream for foam pine surge mixed with air is ejected from two opposing sides of the bathtub (dorsal side 9 feet side). In this jet mode, the dorsal and leg sides can be used independently, or both can be used at the same time, allowing the bather to choose between turning them on and off using independent switches. There is.

The applicant is considering, for example, a bathtub system as shown in FIG. 4 as a bathtub system that can simultaneously filter the water in the bathtub when the jet mode is activated.

As shown in the figure, the bathtub 1 is provided with a suction port 2 on one side wall 1a of the opposing side walls 1a and 1b for guiding the water W in the bathtub to the outside. Two jets are provided on each of the wall portions 1a and lb for mixing air and bathtub return water (the supply system for these will be described later) and ejecting jet streams Ja and Jb for foamy pine surge into the bathtub water W0. Nozzles 3a and 3b are provided.

Each jet nozzle 3a, 3b has an individual air supply pipe 5
a, 5b are connected, and a common air control valve 6 is interposed between each air supply pipe 5a, 5b. The suction port 2 and the suction side of the circulation pump 8 are connected via an upstream circulation pipe 7C, and the discharge side of the circulation pump 8 and each jet nozzle 3a are connected to each other via an upstream circulation pipe 7C.
, 3b are connected via downstream circulation piping 7a, 7b, respectively, and the circulation piping 7 is constituted by the upstream circulation piping 7C and the downstream circulation piping 7a, 7b. Each downstream circulation piping? Return water control valves 9a, 9 for a, 7b, respectively
b is interposed.

Branch portion 7d of circulation piping 7 on the downstream side of circulation pump 8
An inlet of a steam/water separation tank 11 is connected to a branch pipe 10 from the tank, and a pipe 12 is connected to one outlet of the steam/water separation tank 11
The inlet of the filtration tank 15 is connected via the first three-way valve 13 and piping 14. The outlet of the filtration tank 15 is the pipe 1
6, a second three-way valve 17, and a merging pipe 18, it is connected to a merging portion 7e of an upstream circulation pipe 7C between the suction port 2 and the circulation pump 8 in the circulation pipe 7. A drain pipe 19 is connected to the first three-way valve 13, and the second three-way valve 17 and the other outlet of the steam/water separation tank 11 are connected to the pipe 2.
Connected via 0.

A plurality of air blow nozzles 21 are provided on the bottom wall IC of the bathtub 1, and these air blow nozzles 21 are connected to an air pump 24 for air blowing via a header 22 and air blow piping 23, and an air blower is connected to the air blow piping 23. A control valve 25 is interposed.

The remote control operation unit 26 includes an operation switch S1, a back jet switch S8, a foot jet switch S1, a backwash switch S4, and an air blow switch S.

, an up/down key S4 for adjusting the amount of jet water on the back side, an up/down key S1 for adjusting the amount of jet water on the foot side, an amplifier down key S8 for adjusting the amount of jet foam, an amplifier down key S for adjusting the amount of air blow foam, and a liquid crystal display panel 27. It is provided.

The sequence controller 28 controls the air control valve 6, the circulation pump 8, the return water control valves 9a and 9b, and the first and second three-way valves 13 based on various commands from the remote control operation unit 26.
．． 17, the air pump 24, and the air blow control valve 25, corresponding elements are sequentially controlled. The two-dot chain line is
Their control systems are shown.

Next, the operation of this conventional bathtub system will be explained.

When the operation switch SL is pressed, the sequence controller 2
8 is activated.

So, dorsal jet switch S! Or when the foot jet switch S is pressed, the sequence controller 2
8 performs dorsal or foot jet mode. That is, the bathtub water sucked out from the bathtub 1 flows as shown by the solid line arrow, and a part of it is purified by filtration.
This purified water mixes with air and is ejected back into the bathtub water W as a jet stream for foamy pine surge. In addition, dorsal side jet switch S2 or foot side jet switch S
, or is pressed again, the sequence controller 28
stops the circulation pump 8 and ends the jet mode.

Then, when the backwash switch S4 is pressed, the sequence controller 28 executes a backwash mode for washing the filtration tank 15. That is, the bathtub water sucked out from the bathtub 1 flows as shown by the broken line arrow, removes dirt accumulated in the filtration tank 15, regenerates the filtration tank 15, and drains the dirt-containing bathwater. Note that when the backwash switch S4 is pressed again, the sequence controller 28 stops the circulation pump 8 and ends the backwash mode.

Further, when the air blow switch S is pressed, the sequence controller 28 opens the air blow control valve 25 and drives the air pump 24, thereby controlling the air blow.
The air blow switch S is used to blow air from the nozzle 21 to the water W in the bathtub, enveloping the entire body of the bather.
, or when pressed again, stops air blow mode operation.

<Problems to be Solved by the Invention> In the conventional bathtub system described above, the bathtub water is filtered and cleaned while the jet mode is being executed, and the filtration can be performed after bathing for the next bather. It's gone.
