Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a flush toilet having a cleaning nozzle for cleaning a local area such as a toilet user with cleaning water.

(Prior Art) Conventionally, a flush toilet with a cleaning device equipped with a cleaning nozzle for cleaning a local area of a toilet user, etc., is provided by pressing a predetermined cleaning switch after toilet while the toilet user is sitting on the toilet bowl. The hot water heated to an appropriate temperature in the hot water tank is passed to the washing nozzle by the electromagnetic pump, and the hot water is ejected from the washing nozzle toward the local area.

(Problems to be Solved by the Invention) In the case of the above-described conventional flush toilet with a cleaning device, the flush water ejected when the toilet user or the like flushes the local area is warm water heated in the warm water tank.

However, some people want cold water as the wash water in the summer, and some people like hot water.Therefore, some people who want cold water lower the predetermined temperature of the wash water and reduce the power of the heater installed in the hot water tank. However, if you do not heat the cold water injected into the hot water tank, if the next person is a person who likes hot water, you will have to wait until the cold water in the hot water tank is heated to an appropriate temperature. There was a problem that it was very inconvenient. In addition, there is a means to use an instantaneous water heater to quickly turn cold water into hot water, but since the required amount of hot water jetted from the washing nozzle per unit time is large, it is necessary to warm the washing water to an appropriate temperature. Had to use a large capacity heater, and it was virtually impossible to use an instantaneous water heater.

Therefore, in the present invention, a switching valve for switching between hot water and cold water is used, and the wash water can be arbitrarily switched to hot water or cold water, and the wash water is jetted from the washing nozzle according to the taste of each person. This is a technical issue to be solved.

(Means for Solving the Problem) The technical means for solving the above-mentioned problems include a pump and a cleaning nozzle for ejecting cleaning water for cleaning the local area of the toilet user or the like while the toilet user or the like is seated. A flush toilet with a washing device equipped with a hot water jet switch that is operated when hot water heated to a required temperature in a hot water tank is jetted from the washing nozzle, and cold water that is not heated in the hot water tank is the washing nozzle. To select the hot water flow passage and the cold water flow passage leading to the washing nozzle according to the respective signals when the cold water jet switch operated when the water is jetted from the outside and the hot water jet signal and the cold water jet signal from the outside are energized Switching valve,
When an operation signal from the hot water jet switch or an operation signal from the cold water jet switch is input, the hot water jet signal or the cold water jet signal is output corresponding to each operation signal to control the switching valve. And a control means for driving the pump to eject hot water or cold water from the cleaning nozzle.

(Operation) In the flush toilet with a cleaning device having the above-described configuration, when the toilet user or the like prefers warm water as flush water, when the hot water jet switch is pressed, an operation signal from the hot water jet switch is input to the control means. The control means outputs a hot water jet signal to the switching valve to select the hot water flow path, drive the pump to jet hot water from the washing nozzle, and wash the local area such as the toilet user.

On the other hand, when the user, etc., prefers cold water as washing water, when the cold water jet switch is pressed, the operation signal from the cold water jet switch is input to the control means, so the control means jets cold water to the switching valve. A signal is output to select a cold water flow path, and a pump is driven to eject cold water from a cleaning nozzle to clean a local area such as a user.

(Embodiment) Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view of a flush toilet bowl 1 with a cleaning device.

As shown in the figure, a low tank 3 is provided at the rear of the toilet body 2.
Is provided, and tap water is supplied to the raw tank 3 via the water stopcock 4. A ball tap 5 and a float 6 are provided in the low tank 3, and when the float 6 floats to a predetermined height due to an increase in the supplied tap water, the tap water supply is stopped. At the same time, the water injected into the warm water tank 9 through the service tank 7 and the water supply hose 8 also becomes full. The hot water tank 9 is provided with a temperature sensor 10 such as a thermistor and a hot water heater 11 for heating the supplied water to make it warm water, and the supplied water is heated to a preset temperature. When the temperature sensor 10 detects that it has been heated, the hot water heater 11
The power supply to is turned off.

On the other hand, a cold water hose 13 connected to the service tank 7 and a hot water hose 14 for passing hot water from the hot water tank 9 are connected to each of the two water inlet ports 12A and 12B of the three-way valve 12, A suction port side of an electromagnetic pump 16 is connected to a water outlet port 12C of the three-way valve 12 via a hose 15. An accumulator 17 is provided on the discharge side of the electromagnetic pump 16.
The accumulator 17 is provided in order to make the spraying state of the cleaning water sprayed from the cleaning nozzle 18 connected to the outlet side of the accumulator 17 uniform. A solenoid for switching the jetting angle of the washing nozzle 18 to be suitable for local washing of a person (not shown) sitting on the toilet seat 19 or for female local washing.
20 are provided.

On the left-hand wall surface of the person seated on the toilet seat 19, there is provided an operation box 23 to which a hot water jet switch 21 and a cold water jet switch 22 which are operated when jetting hot water or cold water from the washing nozzle 18 are attached. The hot water jet switch 21 and the cold water jet switch 22 are electrically connected to a control circuit (not shown in FIG. 1) provided on the toilet body 2 side through an electric wire inserted through a conduit tube 24.

FIG. 2 is a block diagram showing a water supply path and an electric control circuit of the flush toilet bowl 1 with a cleaning device.

In FIG. 2, a control circuit 30 (not shown in FIG. 1) is shown, and the three-way valve 12, the electromagnetic pump 16, and the hot water heater 11 are connected to the output side of the control circuit 30. The temperature sensor 10, the hot water jet switch 21, and the cold water jet switch 22 are connected to the input side of the control circuit 30.

In the flush toilet 1 with a cleaning device configured as described above, when the flush water is jetted from the flush nozzle 18 while the toilet user is sitting on the toilet seat 19, if the flush water is hot water,
When the hot water jet switch 21 attached to the operation box 23 is pressed, a signal from the hot water jet switch 21 is input to the control circuit 30, so that the control circuit 30 opens the hot water passage from the hot water tank 9 to the three-way valve 12. In addition to the above control, the electromagnetic pump 16 is driven to eject hot water from the cleaning nozzle 18 for a predetermined time.

On the other hand, when the urinal prefers cold water as the wash water for the summer, when the cold water jet switch 22 is pressed, the signal from the cold water jet switch 22 is input to the control circuit 30, so the control circuit
Reference numeral 30 controls the three-way valve 12 to open the cold water passage communicating with the service tank 7 and drives the electromagnetic pump 16,
Cold water is jetted from the cleaning nozzle 18 for a predetermined time. In this way, the toilet user can eject hot water and cold water as washing water according to his / her preference.

(Effects of the Invention) According to the present invention as described above, when the toilet user or the like cleans the local portion while sitting on the flush toilet, hot water or cold water can be arbitrarily timed according to the preference of the toilet user or the like. The effect is that it can be ejected from the cleaning nozzle.
