DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a bathroom device using a water pumping mixing valve for supplying hot water to mix hot water and water to obtain an appropriate temperature.

2. Description of the Related Art Conventionally, there have been hot water mixing valves for this type of bathroom equipment as shown in FIGS. 7 and 8. (For example, JP-A-61
-116187 Publication) In Fig. 7, the flow rate of hot water is adjusted by a water valve 1 provided in the water supply route and a hot water valve 2 provided in the hot water supply route, and the temperature of the mixed hot water is detected by a temperature sensor 3. . Then, the electric switching valve 4 switches the supply destination of the mixed hot water to the flusher 5 or the shower 6. water valve 1
The hot water valve 2 and the electric switching valve 4 are controlled by a controller 8 using signals from the operation panel 7 and the temperature sensor 3. The groove structure of the operation panel 7 is constructed as shown in FIG. A water switch 9 for instructing the start of hot water supply and setting the approximate temperature level, and a cold/hot water switch 10.
! Switch 11, rising switch 1 to select dome hot water
2. Down switch 13 to select lukewarm water, high flow switch 14 to select high flow rate, low flow switch 15 to select low flow rate, selector switch 16 to select hot water supply light from the flush 5 side or the shower 6 side; Switch 1 to stop hot water supply
7 constitutes an operation panel 7.

The operation of this conventional example is, for example, when you want to take a shower, you operate the cold/hot water switch 10, select the mixed water temperature with the increase switch 12 or decrease switch 13, and select the flow rate with the high flow rate switch 14 or the low flow rate switch 15. Then, use the changeover switch 16 to select the shower 6 side. If you want to use it in a flush mode, select the mixed water temperature and flow rate in the same way, and select the flush 5 side with the changeover switch 16. If you press the changeover switch 16 to switch to the shower 6 side while dispensing high-temperature hot water from the shower 5 side, if the set temperature is 45°C or higher, the electric switching valve 4 will switch the shower 6 side to the shower 5.
It is controlled so that it does not return to the side. If the set temperature is lower than 45°C, hot water continues to be dispensed from the shower 6. If, for example, the field switch 11 is pressed while hot water is being dispensed from the shower 6, it is determined that the set temperature is 45°C or higher, and the electric switching valve 4 is automatically switched to the switch 5 side.

Problems to be Solved by the Invention However, the conventional pumping water mixing valve having the above-mentioned configuration has the following problems when used in a bathroom.

(1) This hot water mixing valve is designed so that the plunger 5 can be used by swinging between the bathtub and the washing area, and the shower 6 can also be used by switching, but since it is not possible to use the bathtub and shower at the same time, for example, when taking a bath, It was inconvenient because I was thirsty and couldn't take a shower while raising the temperature of the bathtub.

(After entering the bathtub from Noi Karan 5, set the temperature to 4.
Even if the temperature was lowered to below 5°C and the shower 6 was used, the hot water remaining after the water valve 1 and the hot water valve 2 was supplied from the shower 6, which was dangerous.

(3) The temperatures often used in bathtubs and washing areas or showers are different. (For example, taking into account that the hot water in the bathtub is somewhat cooled, the temperature is 45°C in the washing area, and the temperature in the shower is 42°C.)
°C, etc.) Therefore, it was necessary to operate many switches to distinguish between the two, making it difficult to use.

The present invention solves these conventional problems, and aims to provide a bathroom device that is safe and easy to use.

Means for Solving the Problems In order to solve the above-mentioned problems, the bathroom device of the present invention includes a first water pumping mixing valve that can set hot water for supplying hot water to the bathtub, and a first pumping water mixing valve that can set hot water for supplying hot water to the shower. The second pumping water mixing valve is provided with a second pumping water mixing valve that can set a lower temperature than the pumping water mixing valve of the first pumping water mixing valve and cannot set high temperature hot water.

Effects of the present invention With the above-described configuration, the first hot water mixing valve and the second hot water mixing valve supply hot water at a temperature suitable for each hot water supply object to bathtubs and showers that require different temperature ranges, Prevents hot water from being supplied from the shower,
The aim is to improve usability by eliminating the need to frequently change the temperature setting or switch targets for firing.

Example Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, hot water heated by a water heater 18 passes through a hot water supply route 19, and water passes through a water supply route 20 to a first immersion mixing valve 22 provided for a bathtub 21, and a washing area 23 and a shower 24. The second hot water mixing valve 25 provided at The setting device 26 of the first pumped water mixing valve 22 and the setting device 27 of the second four-water wet joint valve 25 are constructed as shown in FIGS. 2 and 3. The first water pumping mixing valve 22 is for a bathtub;
A hot water switch 28 is provided since hot water is required at the hot water station. The hot water supply switch 29 starts and stops hot water supply, and hot water is supplied at a predetermined temperature, flow rate, and cumulative flow value. (For example, 45°C 118ff/min,
2001), if you want to change from this predetermined value to a different value, operate the temperature up switch 30, down switch 31, water switch 32, hot water switch 28, flow rate up switch 33, and down switch 34. The set values and current values of temperature and flow rate are displayed on the display sections 35 and a6.

For safety reasons, hot water can be turned on only after pressing both the up switch 30 and the high temperature water switch 28.

can only set the hot water temperature up to 45°C, so
The configuration is such that it is impossible to set a temperature that would be dangerous if used in the shower 24, such as hot water or hot water. Switching between the shower 24 and the washing area 23 can be performed using a changeover switch 39. The temperature and flow rate suitable for use in the shower 24 and washing area 23 are preset in the hot water switch 38. (For example, 42° C., 156/min) The main parts of the first hot water mixing valve 22 and the second water shortage mixing valve 25 are constructed as shown in FIG.

Check valves 40, 41 are provided on the hot water side path 19, the water side, and the path 20, and the hot water and water entering the valve frame 42 pass through a pressure balance valve 43 that balances the pressure, and then reach the hot water side valve 44. and reaches the water side valve 45. The hot water side valve 44 and the water side valve 45 are driven by externally provided motors 46 and 47 via reduction gears 48 and 49. 50.51 is a valve position detection means. The mixed water temperature is detected by a thermistor 52, and the mixed flow rate is detected by a flow rate sensor 5.
Detected at 3. In the case of the second pumped water mixing valve 25, the electric switching valve 54 performs switching in conjunction with the changeover switch 39. Signals from the thermistor 52, flow rate sensor 53, and setting device 25 are transmitted to the controller 55, and the controller 55 controls the motor 46.
, 47, the switching valve 54, and the display section of the setting device 25 are controlled.

In the case of the first pumped water mixing valve 22, the structure is almost the same except for the switching valve 54.

Next, the operation of this embodiment will be explained. When filling the bathtub with hot water, the setting device 26 of the first hot water mixing valve 22 is operated and the hot water supply switch 29 is pressed, and hot water is supplied under preset hot water supply conditions. (45°C1181!/m1n) When the preset cumulative flow rate is reached, the quantitative value (2001)
The water will be shut off once the water has reached this point. When using hot water in the washing station 23 or shower 24, open the second hot water mixing valve 25.
When the hot water supply switch 38 is pressed, hot water is supplied under predetermined hot water supply conditions. (42°C, 15j'/m1n)
If you want to raise the shower temperature a little, switch up switch 3.
If you press 7, you can increase the temperature by 1°C each time you press it, but 4
The temperature cannot be set above 5°C. If you enter the bathtub 21 and find that the water temperature is too low, operate the setting device 26 of the first pumped water mixing valve 22 and press the amplifier switch 30 and the high temperature water switch 2 at the same time. 'C

In addition, when setting up a bathtub 21, by placing the shower 24 facing the bathtub 21, hot water can be supplied from the first hot water mixing valve 22 and the second water pumping mixing valve 25 at the same time, so hot water can be filled quickly. It is.

In this case, if the second water pumping mixing valve 25 is also provided with a constant water stop function, the sum of both can be set to be the amount of hot water in the bathtub (200e).

If you want to stop the hot water supply manually, press the hot water supply switch 29.
．． Press 353 again to stop. The operation of the pumping water mixing valves 22 and 25 corresponding to these operations is as follows: Water is stopped by closing the hot water side valve 44 and water side valve 45, and hot water supply is started by opening both valves. It is done. The flow rate is determined by the value of the flow rate sensor 53 and the setting device 22. (25) are compared, the opening degrees of the hot water side valve 44 and the water side valve 45 are adjusted, and the temperature is determined by the thermistor 52 and the setting device 22. The values of (25) are compared,
The flow rate ratio between the hot water side valve 44 and the water side valve 45 is adjusted. The integrated flow rate is calculated by integrating the value of the flow rate sensor 53 by the controller 55, and when the integrated flow value determined by the setting device 22 is reached, the hot water side valve 4 is
4 and the water side valve 45 are closed.

Next, the effects of this embodiment will be described.

The second hot water mixing valve 25 also serves to supply hot water to the shower 24 and the washing area 23, so there is no need to install another hot water mixing valve in the washing area, which has the effect of being easy to install and providing at low cost. are doing. The washing area 23 may be accessed from the first water mixing valve 22. In the washing area, compared to the shower 24, even if high-temperature water is supplied, there is very little danger.

Since the first hot water mixing valve 22 and the second pumping water mixing valve 25 can be controlled in a hypostatic manner, hot water can be supplied by simply operating the hot water supply switch 29, 38 according to predetermined values of temperature, flow rate, and integrated flow rate. It is very easy to operate, and
It can also be displayed easily.

Since the first hot water/water mixing valve 22 has a constant current water shutoff function, when filling the bathtub with hot water, it is convenient and does not overflow, and there is no wasteful consumption of hot water.

Note that the configuration of the setting devices 28 and 27 as shown in FIGS. 5 and 6 is also conceivable.
