Description

[Detailed Description of the Invention] The present invention relates to a two-can, two-channel type bathtub with hot water supply that is equipped with a hot water heat exchanger and a bath heat exchanger independently.

In this type of bathtub, which the present applicant has already proposed in Publication of Utility Model Publication No. 53-40339, as shown in FIG. A knob 3, a gas valve knob 4, a shower knob 5 and a faucet knob 6 are arranged in a concentrated manner at the rear of the upper surface, and a shower joint 7 and a faucet joint 8 are interposed on the outside of the shower knob 5 and faucet knob 6, respectively. A shower 9 and a faucet 10 are connected, and a hot water supply piping connection port 11 is provided in the middle part so that hot water supply piping (not shown) can be connected to a desired location. When using the shower 9 and the faucet 10 separately in this type of bathtub, it is necessary to turn both the shower knob 5 and the faucet knob 6 to open and close both hot water baths. Further, as mentioned above, the shower joint 7, the faucet joint 8, and the hot water supply pipe connection port 11 are provided near the shower knob 5 and the faucet knob 6, resulting in extremely poor operability.

The present invention provides a bathtub with hot water supply that eliminates the drawbacks of conventional products and improves operability.

In order to achieve the above objectives, this invention
A hot water valve with a mechanism for switching hot water supply to the shower or faucet is connected to the hot water heater downstream of the water heater heat exchanger, and a window hole is provided in the front of the operation panel placed on the front upper part of the housing. , a knob for the hot water heater is disposed on the upper surface of the operation panel, and a switching lever for the hot water valve is provided protruding from the window hole, and the switching lever opens the hot water heater after switching between the shower and the faucet. This provides a bath kettle with hot water supply.

An example of implementing the present invention will be described below with reference to the accompanying drawings.

FIG. 2 is a perspective view showing an embodiment of the present invention, and in FIG. 2, parts given the same reference numerals as those in FIG. 1 indicate constituent elements that perform the same functions. In Fig. 2, 1 is a housing, 2 is an operation plate placed on the front upper part of the housing 1, and a hot water supply knob 13 is located at the front center of the upper surface of the operation plate 2, and a central part is located at the rear. Hot water adjustment knob 3 on the left, gas valve knob 4 on the right
are mounted on the operating shafts of the hot water heater, hot water regulator, and gas valve (not shown except for the hot water heater). Further, a shower 9 is connected to the front left side of the operation panel 2 via a shower joint 7, and a faucet 10 is connected to the upper surface of the operation panel 2 behind the gas valve knob 4 via a faucet joint 8. There is. Reference numeral 11 denotes a hot water supply piping connection port provided on the upper rear surface of the housing 1, and a hot water supply pipe (not shown) is connected to this to supply hot water to a desired location outside the bathroom. 12
is a bulge that is integrally formed in the center of the front surface of the operation panel 2 and also serves as a shower hanger, and a switching lever 21d, which will be described later, is inserted through a window hole 12a formed approximately in the center of the bulge 12. is installed protrudingly.

Next, Fig. 3 shows a cross-sectional view of a switching mechanism of a hot water valve which is an essential part of the present invention and which is integrated with the hot water supply valve to switch hot water supply to the shower or faucet, and Fig. 4 shows a partial cross-sectional view of the hot water supply valve of the hot water valve as seen from the direction of arrow A in Fig. 3. In these figures, 14 is a hot water valve, 14a is a valve housing, 15 is a hot water valve inlet connected downstream of the hot water heat exchanger,
Reference numeral 16 denotes a faucet side outlet connected to the faucet joint 8, 17 denotes a shower side outlet connected to the shower joint 7, 16a and 17a denote valve seats, 18 denotes a switching spindle, and 19 denotes a valve body fixed to the spindle 18. The valve body 19 is biased by a spring 20 in a direction in which it is pressed against the valve seat 16a. This bias causes the valve body 19 to come into contact with the spindle 18 protruding from the valve case 14a, and the cam plate 2 is pressed against the spindle 18.
1 is pivotally supported by a shaft 21a, and two cam recesses 21b, 21c are formed on the cam plate 21, and the distances between the cam recesses 21b, 21c and the shaft 21a are made different. When a switching lever 21d protruding from the cam plate is tilted downward, for example as shown in FIG. 3, the tip of the spindle 18 abuts against the cam recess 21c, causing the valve body 19 to abut against the valve seat 17a against the spring 20, closing the shower side outlet 17 leading to the shower 9 via the shower joint 7. Conversely, when the switching lever 20d is tilted upward,
The tip of the spindle 18 abuts against the cam recess 21b, and the pressure of the spring 20 causes the valve body 19 to abut against the valve seat 16a, closing the faucet side outlet 16 leading to the faucet 10 via the faucet joint 8. In addition, a hot water supply faucet 24 holding a valve body 23 is screwed into the valve case 14a.
3 is placed opposite the opening end of the hot water inlet 15, and the hot water heater 2
By opening the door 4, hot water can be dispensed from the shower 9 or faucet 10 selected as described above.

As described above, in the present invention, the switching lever 21d is provided protruding from the window hole 12a formed on the front surface of the operating panel 2, the switching lever 21d is operated to switch, and is disposed in front of the upper surface of the operating panel 2. Hot water tap knob 13
can be opened to selectively switch hot water supply to the shower 9 or faucet 10. Further, since there are no joints that would interfere with operation near the switching lever 21d and the hot water tap knob 13, the operability is extremely excellent and no erroneous operation occurs. Especially when washing your hair in the bathroom,
This is effective because hot water can be supplied without any erroneous operation when the shower 9 or faucet 10 is operated by hand.
