Description

[Detailed description of the invention] This invention connects a water supply hose to a blow-out nozzle that is arranged toward the contraction part connected to the hot water chamber of the jet pump.
In a shower device in which a shower pipe equipped with a shower head is connected to a condenser section, and the lower end of a hot water sampling pipe connected to a bathtub is suspended into hot water in a bathtub, the shower pipe and the water supply pipe are connected with a control valve. This invention relates to a hot water temperature adjustment mechanism for a shower device characterized in that it is connected by a bypass pipe equipped with a jet pump, and allows a user to extremely easily adjust the temperature of hot water in a shower device using a jet pump.

Hereinafter, the present invention will be explained based on the drawings of the embodiments.

FIG. 1 is a perspective view showing an embodiment of the shower device of the present invention;
FIG. 2 is a sectional view showing the structure of the jet pump.

In the figure, 1 is a bathtub, 2 is a bathtub, and both are connected by an upper circulation pipe 3 and a lower circulation pipe 4.

5 is a jet pump with a large diameter water chamber 5a as shown in FIG.
A blow-off nozzle 5b is inserted into the inner space of the water chamber 5a, and its tip is arranged toward a narrow diameter contraction part 5c connected to the hot water chamber part 5a.

A shower vibro is connected to the contraction part 5c, and a water supply pipe 8 guided from a serpentine lower part of the water supply is connected to the blow-off nozzle 5b.

Furthermore, a hot water sampling pipe 9 is connected to the hot water chamber 5a.
A hot water stop cover 10 is connected to the lower end of the .

The hot water stop cover 10 is attached to the side wall of the bathtub 1 near the hot water outlet of the upper circulation pipe 3, as shown in FIG.

Reference numeral 11 denotes a bypass pipe that connects the water supply pipe 8 and the shower vibro, and a control valve 12 is installed in the middle of the bypass pipe.

Now, when the tap water snake lower is opened and tap water is spouted from the blow-off nozzle 5b, it flows into the shower vibro through the condenser section 5c, but the pressure inside the hot water chamber section 5a decreases, so water is discharged from the hot water sampling pipe 9. Suction up the hot water in bathtub 1.

Since the lower end of the hot water sampling pipe 9 is located near the hot water outlet of the upper circulation pipe 3, the high temperature hot water boiled in the bath pot 2 is blown up, and the tap water spouted from the blowing nozzle 5b is The mixed current flows through the shower vibro, and the shower head 13 installed at the tip of the shower vibro also ejects water.

Here, by operating the control valve 12 of the bypass pipe 11 to adjust its opening degree, the pressure of the tap water spouted from the blow-off nozzle 5b and the amount of hot water blown up from the hot water sampling pipe 9 can be adjusted. The temperature of the hot water spouted from the shower head 13 can be adjusted.

Note that the structure of the jet pump 5 is not limited to that shown in FIG. 2.

As shown in FIG. 3, the bypass pipe 11 may be provided in the middle of the water supply pipe 8, or as shown in FIG. 4, the bypass pipe 11 may be buried in the body of the jet pump 5.

Furthermore, as shown in FIG. 5, a thermostat 6a may be attached to the shower vibro, and the thermostat 6a may be connected to a control valve 12 to automatically control the temperature of hot water passing through the shower vibro.

As mentioned above, the water temperature adjustment mechanism of the shower device of this invention is as follows.
The water supply pipe connected to the jet nozzle of the jet pump and the shower pipe connected to the condenser section are connected by a bypass pipe equipped with a control valve, so by operating the control valve, water is sprayed from the shower head. You can adjust the temperature of the hot water.

Since the control valve 12 is exposed to the outside of the jet pump 5,
It can be easily adjusted by the user.
