BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shower device having a plurality of spouts and allowing a user to experience a variety of shower experiences.

0002

2. Description of the Related Art A conventional device as shown in FIG. 4 is known.

Reference numeral 1 denotes a connection port for connecting piping from a water heater. 2 is a hand shower solenoid valve, and 3 is a hand shower spout. 4 is an overhead shower solenoid valve, and 5 is an overhead shower spout. 6 is a solenoid valve for hot water, and 7 is a spout for hot water. 8 is a solenoid valve for a spray shower, and 9 is a spray shower spout. Reference numeral 10 is an operating unit that instructs hot water to be discharged from each of the showers 3, 5, 7, and 9, and 11 is a controller that controls the operation of each electromagnetic valve 2, 4, 6, and 8 according to instructions from the operating unit 10.

[0004] Using the operating unit 10, a shower is selected and an instruction is given. When a spray shower is instructed, the controller 11 receives a signal from the operating unit 10 and opens the spray shower electromagnetic valve 8 to discharge hot water from the spray shower spout 9 and use the shower.

[0005]

[Problem to be Solved by the Invention] However, with the above configuration, when switching to a spray shower while hot water is being used in a hand shower, etc., the flow rate is extremely reduced, the water heater goes out, and the water turns to water. Because of this, only water can be used in spray showers. Therefore, it is not accurate in achieving customer satisfaction.

The present invention solves the above problems and provides a comfortable shower device.

[0007]

[Means for Solving the Problems] The present invention provides a waterway branched off via a branch pipe to one of the waterways led to a plurality of water outlets, and a solenoid valve for spray shower is installed in one of the branched waterways. In addition to providing a spray-like shower spout at the tip,
A hot water sprinkling nozzle is provided on the other side of the branch waterway via a hot water sprinkling solenoid valve, and the hot water sprinkling solenoid valve is connected to a temperature sensor that detects the temperature of the fluid flowing in the spray shower waterway and a flow rate sensor that detects the flow rate. and other solenoid valves.

[0008]

[Operation] When the temperature sensor detects the set temperature, the spray shower solenoid valve opens, and the hot water sprinkling solenoid valve is gradually driven in the closing direction. By doing so, hot water is gradually discharged from the spray shower spout as a hot water spray shower. At that time, a flow rate sensor checks the flow rate of hot water, and if the flow rate falls below the ignition flow rate of the water heater, the solenoid valve for sprinkling hot water is driven in the opening direction to prevent the water heater from extinguishing. By doing so, you can experience a stable hot water spray shower.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. Note that parts that are the same as those in the conventional example are given the same drawing numbers to simplify the explanation.

In FIGS. 1 and 2, 12 is a shower device according to the present invention, and 13 is a water heater that supplies hot water to the shower device 12. 14 is a nozzle for sprinkling hot water;
15 is a solenoid valve for sprinkling hot water. 16 is a switch for a normal spray shower, and 17 is a switch for a hot water spray shower. 18 is a temperature sensor, and 19 is a flow rate sensor. The hot water sprinkling nozzle 14 and the spray shower spout 9 are branched via a T-shaped branch pipe, and the spray shower spout 9 is provided in the upper waterway via a solenoid valve 8, and the solenoid valve 15 is provided in the lower waterway. A nozzle 14 for dispensing hot water is provided through the nozzle 14.

Next, the operation will be explained with reference to FIG. When the hot water spray shower switch 17 is turned on, the electromagnetic valve 15 for sprinkling hot water opens, and the hot water heated by the water heater 13 is guided into the shower device 12 through the connection port 1 and discharged from the nozzle 14 for sprinkling hot water.

When the temperature sensor 18 detects the set temperature (in this embodiment, set at 70° C.), the spray shower solenoid valve 8 opens, and the hot water sprinkling solenoid valve 15 is gradually driven in the closing direction. By doing so, hot water is gradually discharged from the spray shower spout 9 as a hot water spray shower. At that time, the flow rate sensor 19 checks the hot water supply flow rate, and if the flow rate falls below the ignition flow rate of the water heater 13 (in this embodiment, it is set to 31/min), the solenoid valve 15 for sprinkling hot water is driven in the opening direction to supply hot water. It is controlled so that the fire in the vessel does not go out. By doing so, you can experience a stable hot water spray shower.

[0013] Moreover, when the hot water is discharged in the form of a spray, it feels very pleasant and warms the body well. Furthermore, since the particles of the hot water are fine, there is no risk of getting burned even when spraying hot water, and the room temperature in the bathroom rises, creating a sauna effect. In addition, compared to dry saunas, wet saunas place less strain on the heart, even for the elderly and physically weak, and can provide a comfortable sauna experience at home.

Next, the hot water spray shower switch 17 is turned to O.
When the shower is turned off or switched to another shower, the solenoid valve 15 for sprinkling hot water is fully opened and the solenoid valve 8 for spray shower is closed. By doing so, the spray shower stops water and the water nozzle 14
More hot water. Then, the temperature sensor 18 checks the hot water temperature, and the hot water is drained until the hot water temperature drops to the set temperature (in this embodiment, set at 43° C.), and then the water is stopped or the shower is switched to another type. Therefore, even if you use other showers, you can safely use it without being exposed to hot water.

Although not described in detail in this embodiment, the temperature of the supplied hot water can be adjusted and changed automatically or manually using the water heater 13 or a mixing part (not shown) built into the shower device 12. It is something.

[0016]

As described above, according to the shower device of the present invention, the following effects can be obtained. (1) Spray shower While using a hot water spray shower from the spout, the flow rate sensor checks the flow rate of hot water, and if the flow rate falls below the ignition flow rate of the water heater, the solenoid valve for sprinkling hot water is gradually driven in the opening direction to supply hot water. Even if you use a spray shower, the water heater will not go out, so you can experience a stable hot water spray shower. (2) When the hot water spray shower ends and you switch to another shower, the solenoid valve for sprinkling hot water is fully opened and the solenoid valve for spray shower is closed. By doing so, the water from the spray shower will stop and hot water will be discharged from the hot water nozzle. A temperature sensor checks the temperature of the hot water coming out and drains the water until the temperature drops to a low temperature, so you don't have to worry about getting burned even if you switch to another shower.
