DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub system in which a circulating hot bath apparatus is integrated with a bathtub.

[0002]

2. Description of the Related Art Circulating hot water baths are known which circulate warm water in a bath tub to purify and reinforce minerals, and also heat the bath to an appropriate temperature and return it to the inside of the bath tub. This product generally has a built-in filtration tank that stacks a normal filter and a mineral ore particle layer, removes trash such as hair in warm water with a normal filter, and reinforces minerals in warm water with a mineral ore particle layer. Each of these devices is housed in a compact case so that it can be attached to an existing bathtub.

[0003] The case is installed here when there is an installation space on the extension line of the bathtub rim portion, and when there is no installation space, it is installed in the washing place. In any case, a dangerous substance that requires attention in terms of a relatively large electric shock or the like is installed as a hindrance in a bathroom in a limited space and in a water place where a person is naked. Therefore, the diameter is reduced toward the bottom made of molded products such as glass fiber reinforced unsaturated polyester resin (FRP) and acrylic artificial marble, and has a peripheral rim at the upper end, and a cosmetic apron on the surface facing the washing place. In the vertical type bathtub, in the dead space below the rim, the devices housed in the case and the hot water inlet / outlet pipe are arranged so that no obstacles need to be present in the bathroom. It is commercially available. That is, as shown in FIG. 18, a suction port 3 and a discharge port 4 are arranged on one short side 2 side of the bathtub 1, and pipes 3a and 4a for communication between the devices are extended behind the apron 5. Each of the devices 9 in the case is flattened in a space below the rim 7 on the other short side 6 side, and the slide bracket 8 is assembled.

[0004] The maintenance staff removed the apron 5,
The slide bracket 8 is drawn out.

[0005]

In the circulating hot bath apparatus, the filter described above becomes clogged with prolonged use, and mucoadhesion due to dirt occurs on the surface of the ore grain layer, Although regular cleaning and replacement are required, such frequent maintenance is introduced in the conventional technology. In this case, the apron 5 is removed, the slide bracket 8 is pulled out, and the reverse operation is performed. This is extremely inconvenient because the housewife has to do it under difficult tasks.

SUMMARY OF THE INVENTION The present invention has been made in view of such problems of the prior art, and has as its object to remove the maintenance of a filter and a mineral ore layer by removing an apron, removing a bathtub rim. It is an object of the present invention to provide a bathtub system in which a circulating warm bath apparatus that can be drawn out without drawing out each device in the space and the reverse work is integrated with the bathtub.

[0007]

In order to achieve the above object, a bathtub system in which a circulating hot bath apparatus according to the present invention is integrated with a bathtub is provided with a suction port and a discharge port on one short side of the bathtub. And the rim surface on the one short side in a state where the components of the hot bath apparatus except for the filtration tank are assembled to the slide bracket provided on the other short side, and the filtration tank is separated from the respective apparatuses of the hot bath apparatus. The opening / closing lid is vertically installed so that the suction port, the discharge port, each device, and the hot water inlet / outlet pipe communicating between the filtration tank extend behind the apron.

[0008] The filtration tank is preferably separated into a filter tank and an ore grain tank. It is preferable that the filtration tank is disposed in the suction system.

[0009]

[Action] The maintenance of the filtration tank can be done without removing the apron through the detachment of the opening / closing lid, which looks into the rim surface of the bathtub (actually a makeup lid is placed on the top), without having to pull out the slide bracket. obtain. At this time, if the filter and the mineral ore particle layer are separated and independent from each other, it is possible to suitably maintain both of the different maintenance periods and reduce the tank diameter, which is advantageous in design.

Further, if the filtration tank is arranged in the suction system, a strong lock at the time of closing the lid is not required due to the suction action of the opening / closing lid due to the negative pressure in the tank, and it is easy to handle.

[0011]

1 to 5 show an embodiment of the present invention.
It will be described based on. 1 and 2 show a mode in which a filter tank 10 in which a filter and a mineral ore layer are integrated on the short side 2 side and an opening / closing lid 11 is viewed on a rim 14 surface (actually, a decorative lid 41 arranged on the upper side). And the other devices such as the pump 12 and the heater 13 are assembled to the slide bracket 8 on the short side 6 side, and these devices, the filtration tank 10, the suction port 3, and the discharge port The suction system piping 3a and the discharge system 4a that communicate between the four are shown to extend behind the apron 5 (the washing area is opposite to that in FIG. 18).

This basic specification is shown in FIG.
Is disposed downstream of the pump 12, so that the pressure system is disposed, and the filtration tank 10 has an internal pressure. Therefore, the opening / closing lid 11 must be of a type that is securely locked by screwing or the like. There is. As shown in FIG. 4, the filtration tank 10 is separated into a filter tank 10a and a mineral ore tank 10b, and both of them are provided on the rim 14 on the short side 2 side.
If the decorative lids 41 and 11 are installed in a manner in which the decorative lids 1 and 11 can be seen (as described above, there is an advantage that the filters and the mineral ore with different maintenance periods can be separately maintained. The basic specifications in this case are shown in FIG.
Is shown in

[0013]

Next, an embodiment of a so-called suction system in which a filtration tank is arranged upstream of a pump will be described with reference to FIGS. In the circulation type hot water bath, only Japanese Patent Application Laid-Open No. 6-208647 of the applicant assigns the filtration tank in the suction system.

This type of suction system has a special advantage.
The present applicant has proposed an advantageous filtration tank in Japanese Patent Application No. 7-232388. That is, as shown in FIG. 6, an inlet 17 and an outlet 18 are provided at the bottom of the filtration tank 10, and the pump 12 is connected to the outlet 18 side to form a suction system. The tank 10 is fitted with a removable tubular filter 21 having an ore grain layer 19 on the inner side and a filter layer 20 on the outer side, and hot water to be treated enters through the inlet 17 as shown by the arrow. After passing through the through-hole portion 22 a of the top plate 22 through the orifice layer 19 and the ore layer 19, it passes through the outlet 18 through the center through tube 23 and reaches the pump 12.

As shown in FIGS. 7 and 8, a foldable handle 16 for lifting the cylindrical filter is attached to the top plate 22, and the top plate 22 is provided with a lower central through cylindrical body. The ore grain layer 19 and the like can be suspended and taken out as being detachably assembled in the vertical direction with the ore 23. The sealing material 24 is attached around the opening / closing lid 11 so as to be in contact with the opening / closing lid 11, but (since the filtration tank 10 is a suction system, no special fixing means is required for the opening / closing lid 11,
If only the peripheral edge seal is secured, the opening / closing lid 11 will naturally adsorb to the tank opening due to the internal negative pressure. ), Mounting hole 2 in the center
5 is bored, and a vertically extending shaft 27 is loosely inserted through the bottom of the knob 26. A ring-shaped packing material 28 made of rubber is tightly fitted to the shaft 27. A locking piece 29 is attached to the lower end of the shaft 27 to prevent the knob 26 from being disengaged.

The ring-shaped packing material 28 controls ventilation and air shielding. That is, in FIG. 9, the ring-shaped packing material 28 tightly fitted to the shaft 27 is sucked by the negative pressure in the tank and is sucked on the peripheral edge of the mounting hole 25 to block air (a). Also,
When the knob 26 is picked up, the ring-shaped packing material 28
Is also lifted, and a ventilation path is formed in the suction surface to ventilate (b).

In spite of the suction system, the maintenance opening / closing lid 11 can be opened simply by picking up the knob 26, and the air shielding required for closing the lid can be realized by merely placing the lid. The maintenance work is remarkably simple compared to the above-mentioned firm lock and the pressing system which has to release this lock.

The applicant of the present invention has also proposed, in Japanese Patent Application No. 8-5732, an improved solution to the inconvenience of shutting off the water channel when the pump of the filtration tank is stopped. That is, as shown in FIG.
Is pierced. Due to this, when the pump 12 restarts and sucks water in the central through-tube 23 and tries to idle, the hot water in the filtration tank 10 does not pass through the upper end of the central through-tube 23, It flows into the outlet 18 through the small through-hole 30.

Thus, even if the space 31 not filled with water is formed, the pump 12 does not run idle when it is restarted. That is, warm water in the filtration tank 10 is supplied as so-called priming water from the small through-holes 30 to the space after the remaining stored water in the central through-tube 23 is sucked. In practice, the pump 12 operates almost normally by priming from the small through-holes 30 while gradually taking in residual air in the space 31.

On the other hand, warm water is sucked up from the inlet 17 into the filtration tank 10 which increases the degree of negative pressure by the suction, and the space 31 which is not filled with water gradually disappears.
Note that, under normal conditions, the main circulation flow path of the hot water is maintained through the upper end of the central through-tube 23, and the necessary contact with the filter medium is ensured. If the pressing system introduced in FIGS. 1 to 5 is changed to a suction system, the operation of the opening / closing lid looking into the bathtub rim surface can be further facilitated.

An embodiment in which a suction tank and a filtration tank are separated will be described below with reference to FIGS. 11 is an overhead view of the entire bathroom, FIGS. 12 and 13 are overhead views of the bathtub, and FIG. 14 is a piping diagram. In the figure, the filter tank 10a,
The mineral ore tank 10b is obtained by slightly improving the filter and the tank 10 of the mineral ore grain layer integrated type shown in FIGS.

That is, the filter tank 10a is arranged as shown in FIG.
As shown in the figure, the blinded filter unit lid 39

An inner body 47 formed by sandwiching the filter layer 20 between the unit cover 39 and the filter holder 43 is inserted into a filter unit case 45 tightly fitted to the outlet 18 and then accommodated therein. . The lid lock 46, which is spring-biased outward on the upper surface of the filter unit lid 39 and can be inserted into a slit provided in the filter unit case 45, is attached to the filter unit lid 39 in this embodiment. By pulling up through the handle 16 (not shown), the filter unit case 45 can be stirred.

After the lifting, the lid lock 46 is retracted to release the integration with the filter unit case 45, the inner body 47 is pulled out of the case 45, and the exposed filter 2 is removed.
Groom zero. In the figure, reference numeral 48 denotes a check valve for preventing a situation in which hot water sucked from the suction port 3 flows backward from the suction port 3, which is preferably disposed at a communication hole with the inlet 17 secured at the bottom of the case 45.

As shown in FIG. 16, the mineral ore tank 10b has a blind ore unit cover 49 (top plate 2).
A center core 51 having a petal cross section (corresponding to the center penetrating tubular body 23, only the upper end of the petal slightly protrudes) is provided with a slit 52 for draining water through a hanging set screw 50 at the center. Secured and suspended, while the center core 5
