[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water inlet cover for a bubble generating bath, and more particularly to a cover shape suitable for preventing hot water from jumping out.

[0002]

2. Description of the Related Art The following is a detailed description of what has heretofore been found in JP-A-6-304219. In the air bubble generator integrated with a bathtub disclosed in Japanese Patent Application Laid-Open No. 6-304219, a bathwater inlet, a bathwater outlet, an air inlet, and a circulation pump are integrally formed in a hole formed in a bathtub side wall. The pump unit is inserted and fixed. The bathwater outlet is located above the bathwater inlet so that air bubbles are not sucked into the bathwater inlet, and the inlet cover attached to the bathwater inlet also serves as the outlet cover. It has become. A bath water suction hole is opened at the lower front of the suction port cover,
Bath water flowing into the pump chamber of the circulation pump from the bath water suction hole formed in the suction port cover is pressurized, and is configured to be jetted into the bath tub from the bath hot water outlet through the discharge path.

[0003]

As described above, in the conventional bathtub-integrated bubble generator, the bathwater inlet is located below the bathwater outlet, so that the water level of the bathwater is set at the bathwater inlet. When the apparatus was operated at a higher temperature and lower than the bath water jet, the bath water jet was spouted from the bath water jet onto the surface of the bath water, and water was sometimes splashed. Further, when the temperature of the bath water is high, there is a danger of burns and the like due to the splash of water. In order to solve the above problems, a water level sensor or the like is provided to regulate the operation at a low water level.However, the size of the device is increased due to an additional sensor element or a control circuit, or the cost is increased. Had the problem of becoming dull.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a hot water suction apparatus capable of preventing splashing by a simple method without increasing the size and cost of the apparatus itself. To provide a mouth cover.

[0005]

Means for Solving the Problems and Action / Effect To achieve the above object, the invention according to claim 1 is to integrally form a bath water inlet, a bath water outlet, an air inlet, and a circulation pump. A bath water inlet cover attached to an air bubble generator that is directly attached to a mounting hole formed in a side wall of the bath tub and ejects a jet of air bubbles into the bath tub. A rectifying plate is provided for restricting the flow of bath water into the bath water inlet when it is below the jet port. In this way, a rectifying plate is provided on the back of the cover to restrict the flow of hot water into the hot water inlet, so when the bath water level is lower than the rectifying plate, the circulating pump cannot sufficiently suck the hot water and the hot water is sucked. The inflow of bath water into the mouth is restricted, so that the bath water can be prevented from jumping out of the bath water spout.

According to a second aspect of the present invention, the straightening plate is formed at a position corresponding to the periphery of the bath water inlet to approximately the same height as the bath water outlet, and near the bath water outlet. It is notched. For this reason, it is possible to prevent the bath water from jumping out of the bath water jet port without increasing the size of the bath water inlet cover more than necessary.

Further, according to a third aspect of the present invention, when the cover is fitted to the hot water inlet, the hot water inlet, the hot water outlet, the air inlet, and the circulation pump are integrated. When the bath water level is lower than the bath water outlet between the pump unit and the pump unit, the flow of the bath water into the bath water inlet is restricted, and the bath water level is In the case of being above the outlet, a cut-out portion provided near the bath hot water outlet forms a bath hot water inflow path to the bath hot water inlet. The hot water flowing into the hot water inlet of the circulating pump unit can be more reliably blocked from the gap between the current plate and the pump unit, and the hot water can be more reliably prevented from being spouted out of the bath water. Can be.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a bath water inlet cover 2 having a current plate 1 according to the present invention and a mounting method thereof, FIG. 2 is a front view of the bath water inlet cover, and FIG. 3 is a direction shown in FIG. FIG. 4 is a perspective view showing a method of inserting the pump unit.

A circulating pump fixing case 9 for inserting and fixing the circulating pump unit 6 from the inner side of the bathtub is provided in an opening 8 formed in the side wall of the bathtub 7. 10, a slip sheet 11, and a fixing nut 12.

A substantially cylindrical circulating pump unit 6 integrally formed with a hot water inlet 5, a hot water jet 4, an air inlet 13, and a circulating pump is provided in the circulating pump fixing case 9 from the inner side of the bathtub. The air suction formed at the upper end of the pump portion of the circulation pump unit is fixed by inserting the grooves formed on the outer periphery of the circulation pump into the protrusions 16 formed on the inner surface of the circulation pump fixed case via the holes 14 and 15. The port 13 is pressed into contact with the air suction path of the circulating pump fixed case via the cylindrical packing 17 to form an air suction path.

A soft hose 19 such as a vinyl hose is connected to the air suction port 18 of the circulating pump fixed case, and the other end of the soft hose is an air suction formed integrally with a switch and a silencer disposed on the flange surface of the bathtub. Connected to the mouth.

Bath water sucked from a bath water inlet 5 formed at a substantially central portion of a front surface of a substantially cylindrical circulating pump unit is centrifugally pressurized by rotation of an impeller 20 located at a rear portion of the suction port, and is supplied to an upper part of the pump chamber. It is ejected from the ejection nozzle 22 on the front surface of the provided volute portion 21.

An air suction passage 13 is formed above and behind the jet nozzle 22, and is configured to mix air into bath water by an ejector effect to generate a bubble jet. Reference numeral 23 denotes a movable throat for changing the direction of the bubble jet.

The bath water inlet cover 2 is formed so as to cover a portion of the circulating pump unit located on the inner surface of the bath tub, and has a filter 3 inserted into and fixed to the bath water inlet and a locking claw 24 around the bath water outlet. Fit and lock and attach.

On the back surface of the bath water inlet cover 2, a rectifying plate 1 is provided in a cylindrical shape having a cut-out upper portion at a portion corresponding to the periphery of the bath water inlet 5 when the cover is attached. The hot water outlet 4 is formed so as to be located.

The height of the current plate 1 is set so as to abut the front surface of the circulation pump unit 6 when the cover is mounted. Therefore, when the cover is mounted, the hot water flowing into the bath hot water inlet is notched in the current plate 1. It will be limited to the part that was.

Next, the operation of the current plate 1 on the bath water will be described. 2 and 3, when the bathtub water level is equal to or higher than the height of the bath water outlet 4, the bath water flows into the bath water inlet 5 from the cutout portion of the rectifying plate 1 to generate a normal bubble jet. However, since the bath water jet port 4 is in the bath water, no water splash is generated by the jet.

When the bathtub water level is higher than the bathwater inlet 5 of the circulating pump unit 6 and lower than the bathwater outlet 4, the flow path of the bathwater into the bathwater inlet 5 is restricted and shut off by the rectifying plate 1. Therefore, the circulating pump cannot sufficiently suck in the bath water, and the circulating pump idles, so that the bath water does not squirt and splashing by the jet can be prevented.

When the bathtub water level is lower than the bathwater inlet 5 of the circulation pump unit 6, the circulation pump cannot suck the bathwater and does not blow out the bathwater.

As described above, no matter where the bathtub water level is at all, there is no need to worry about splashing water, and accidents such as burns can be prevented.

FIGS. 5 and 6 show another embodiment. In the embodiment shown in FIG. 5, the current plate 1 is provided on the pump unit 6 side, and the bath water inlet cover 2 is mounted. At this time, the current plate 1 provided on the pump unit 6 side and the back surface of the bath water inlet cover 2 are in contact with each other to form a bath flow path similar to that of the above-described embodiment.

In the embodiment shown in FIG. 6, a current plate 1 is provided on each of the bath water inlet cover 2 and the pump unit 6 side.
The inflow path is formed by abutting them.
