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

FIG. 1 is a sectional view of a main part of a cleaning apparatus according to an embodiment of the present invention. Water is pumped by a pump 2 and passes through a water supply pipe 3 to a tank 6 having a heater 4 and a temperature detector 5.
Leads to. Further, the water flows from the tank 6 through the hot water supply pipe 7 to an inflow path 12 of a flow rate variable valve 11 which is a flow rate (water force) variable means. The variable flow rate valve 11 includes an inflow path 12 and an outflow path 13.
, A valve body 15 provided in the valve body 14 to vary the flow rate, a valve seat 17 corresponding to a flow control unit 16 receiving the inflow pressure of the valve body 15, and the valve body 1.
And a biasing means 20 for biasing the flow control portion 16 of the valve body 15 in a direction away from the valve seat 17, and a biasing portion thereof. The valve body 15 is moved to the valve seat 17 against the urging force of the means 20.
And a communication passage 22 that connects the cylinder portion 19 and the outflow passage 13 with each other. Further, the electromagnetic drive unit 21 includes the electromagnetic coil 2
3 is provided with a fixed iron core 25 and a movable iron core 26 via a non-magnetic guide tube 24, and a yoke 2 is provided outside the electromagnetic coil 23.
7 and a yoke plate 28 are provided. In addition, the valve element 1
5 and the movable iron core 26 are loosely attached.

When the instruction input means 29 is instructed to select from among a constant flow cleaning mode, a low-speed beat cleaning mode, a high-speed beat cleaning mode, a musical tone-linked cleaning mode, and the like, the power change corresponding to the instruction of the instruction input means 29. The signal is the controller 30
Is output to the electromagnetic drive unit 21 of the variable flow valve 11. For example, when the tone-linked washing mode is instructed, the electric signal of the tone signal generating means 31 is heard as a sound signal from the speaker 32 as a sounding body, and at the same time, the pitch, the loudness or the pitch of the tone signal from the tone signal generating means 31 is changed. A musical element signal such as a rhythm element is converted to musical element extracting means 33.
Is extracted, the musical tone element signal is further input to the controller 30, and an electric signal is output from the controller 30 to the flow rate (water force) control means 11 in accordance with the musical tone element signal. A method of extracting a rhythm element by the musical element extracting means 33 is to extract a rhythm section of a musical sound signal, for example, a frequency band of a sound of a musical instrument such as a drum by a frequency filter, and obtain a current corresponding to the volume of the frequency band. Controller 3
In this configuration, the signal is amplified by 0 and applied to the electromagnetic coil 23 of the flow rate varying means 11.

Next, the flow rate variable valve 11 which is a flow rate (water force) variable means will be described in more detail. The force for attracting the movable iron core 26 of the electromagnetic drive unit 21 of the variable flow rate valve 11 changes according to the current flowing through the electromagnetic coil 23. That is, the electromagnetic drive unit 2
1 in response to the power signal input to the
The pulling force changes against the force of 0. That is, the flow rate (water force) can be varied by changing the current flowing through the electromagnetic drive unit 21. Also, when the electromagnetic drive unit 21 is not energized, the valve body 15 is urged by the urging means 20 so that the flow control unit 16 of the valve body 15 moves away from the valve seat 17 and the flow path is always opened, so that the normally open type valve is opened. Is composed. Further, the valve element 15 has a configuration in which the fluid pressure from the inflow path 12 is received by the flow control unit 16 and the pressure balance unit 18, and most of the mutual operating pressures cancel each other. Therefore, the force required to drive the valve body 15 is only a small electromagnetic force of the electromagnetic drive unit 21.
Also, the feature of this valve is that a suitable amount of water flows without completely closing the flow path even when the valve is fully closed. That is, even when a current flows through the electromagnetic drive unit 21 and the flow control unit 16 of the valve body 15 fully closes the valve seat 17, it passes through a predetermined gap between the outer diameter of the pressure balance unit 18 and the inner diameter of the cylinder unit 9. , And further flows to the outflow path 13 via the communication path 22.

Next, the operation of the above configuration will be described. When the user selects and instructs, for example, the tone fluctuation cleaning mode A by the instruction input means 29, the compact disc player.
A musical sound such as a music, a babbling of a river, a sound of a wave, a voice of a bird, etc. is output from a musical sound signal generating means 31 such as a tape player, an audio reproducing element, a television, a radio, a cable broadcast, etc.
2 and at the same time, from the tone signal generating means 31, a tone element such as a pitch or loudness or a rhythm element of the tone signal is extracted by the tone element extracting means 33, and the signal corresponding to the extracted tone element signal is extracted. The change power signal acts so as to be output from the controller 30 to the flow rate (water force) variable means 11. Therefore, the flow rate (water force) spouted from the washing nozzle 10 automatically changes in response to the musical sound signal heard from the sounding body 32, so that a rhythmic fluctuation washing and a pleasant and comfortable washing can be performed. it can. In the description of the present embodiment, the flow rate (hydraulic) variable means
Although the variable flow rate valve 11 has been described as an example, for example, even if the variable flow rate valve 11 changes the amount of air mixed in with an air pump, the water force spouting from the washing nozzle 10 corresponds to the musical sound signal heard from the sounding body 32. It works so that it changes automatically, and it is possible to perform rhythmic fluctuation cleaning and enjoyable and comfortable cleaning.

Further, the change power signal corresponding to the musical tone element signal acts so as to be output from the controller 30 to the flow rate (hydraulic) variable means 11, and the fluctuation nozzle having a rhythmic sense can be washed out, so that it is ejected from the washing nozzle 10. Comfortable cleaning is possible even if the total flow rate is small. Thus, the cleaning nozzle 10
Can reduce the amount of heating power to make hot water by reducing the total flow rate ejected from the nozzles, and can adjust the amount of air mixed into the washing water by an air pump or the like according to the tone signal to vary the water force ejected from the washing nozzle. By doing so, comfortable cleaning can be performed even with a small flow rate, and a cleaning device with low heating power and low heating power for making the cleaning water warm can be realized.

Further, even when there is no sounding body 32 such as a speaker, the changing power signal corresponding to the tone element signal is output from the controller 30.
Is output to the flow rate (hydraulic) variable means 11, and a fluctuation cleaning with a sense of rhythm is possible, and a comfortable cleaning device can be obtained.

When the user instructs the tone rhythm-linked washing mode by the instruction input means 29, a tone signal is generated from the tone signal generating means 31, and music is heard from the sounding body 32, and at the same time, the rhythm of the music is heard. , The flow rate (water force) of the cleaning water spouted from the cleaning nozzle 10 changes. In this tone rhythm-linked washing mode, the tone signal extracting means 33 extracts a rhythm element from the tone signal and outputs an electric output corresponding to the rhythm element signal to the controller 30.
This is caused by applying an electric current to the electromagnetic coil 23 of the variable flow rate valve 11. At this time, FIG. 2 shows a state where the input current applied from the controller 30 to the variable flow rate valve 11 changes and a state where the washing water changes. As described above, the flow rate (water force) of the washing water ejected from the washing nozzle 10 changes according to the rhythm element signal that changes with time, and rhythmic stimulation can be obtained. In this manner, the variable flow valve 11 is energized only at the instant of each signal in accordance with the sound intensity of the rhythm element that changes with time, and the movable iron is generated by the electromagnetic force generated in the electromagnetic coil 23 of the variable flow valve 11. The core 26 is the valve 1
The instantaneous cleaning flow is reduced to a minimum flow since it acts to overcome and pull in the force of the means 20 for biasing 5. In addition, between the pulses of the rhythm element signal, the input current from the controller 30 to the variable flow rate valve 11 stops, and at that moment, the electromagnetic force of the electromagnetic coil 23 of the variable flow rate valve 11 also disappears. It is fully opened by the force of the biasing means 20 and acts immediately to return to the maximum flow rate.

As described above, in the cleaning apparatus of the present embodiment, the flow rate varying means 11 is a normally-open type and is in an open state when power is not supplied, and acts so as to reduce the flow rate only while power is supplied. Here, even if the flow rate spouted from the cleaning nozzle 10 can be rhythmically changed according to the signal of the musical tone signal generating means 31, it is meaningless unless the original cleaning function is high. Therefore, the change pattern of the flow rate (water force) becomes important. For example, it is desirable that the time ratio between the time when the flow rate (water force) is fully opened and the time when the flow rate is narrowed is set such that the time during which a sufficient flow rate can be secured is longer than the time during which the flow rate is narrowed. The cleaning apparatus according to the present embodiment controls the flow rate (hydraulic) variable means 11 at a short pulse-like energizing time ratio in accordance with the rhythm of a tone signal and the like.
, And acts so as to reduce the flow rate of the washing water ejected from the washing nozzle 10 in a pulsed manner. In other words, comfortable fluctuation cleaning with a rhythmic feeling and a high cleaning effect can be realized with less power consumption. Furthermore, if an abnormally high water pressure acts on the upstream side when the flow rate varying means 11 is not energized, the abnormally high pressure will not occur because the flow rate varying means 11 is a normally open type. Variable flow valve 1
1 to pass through the cleaning nozzle 10 without passing through. That is, in such an abnormal condition, the flow rate varying means 1
It is possible to prevent a component (eg, a container such as the tank 6) upstream of the device 1 or the flow rate varying means 11 itself from being damaged.

In order to obtain the massage effect, unless the flow rate changing means 11 for changing the flow rate of the jet from the cleaning nozzle 10 in a pulse manner is provided as close to the cleaning nozzle 10 as possible, the effect is reduced. Because, for example, tank 6
If the flow rate is changed in a pulsed manner by the flow rate varying means 11, the change becomes dull due to the deformation of the container of the tank 6, etc. The massage effect is also reduced. That is, in a cleaning apparatus for cleaning with a high massage effect, it is necessary to provide the flow rate varying means 11 near the cleaning nozzle 10. Therefore, it is an important point that the flow rate varying means 11 is configured as a normally open type. In addition, even in the case of performing constant flow cleaning without changing the flow rate, it is possible to save unnecessary electric power and time to open by energizing the flow rate changing unit 11.

The variable flow rate valve 11 is a variable flow rate means.
Is the flow control unit 16 of the valve body 15
The pressure acting on the valve body due to the inflow pressure is almost canceled out, and the valve is actuated only by the force of the urging means 20, for example, the electromagnetic force of the electromagnetic drive unit 21 which can withstand about 100 grams. The configuration in which the body 15 can be driven enables lower power driving.

Here, the communication passage 22 is also important for reducing the force acting on the valve body of the fluid pressure and for driving with low power. This is because the communication passage 22 can communicate the back pressure chambers of the pressure balance section 18 and the flow control section 16 with each other, thereby canceling the inflow pressure.

As described above, in the cleaning apparatus of the present embodiment, the inflow pressure of the variable flow rate valve 11 acts on the flow rate control section 16 and the pressure balance section 18 of the valve body 15, and most of the mutual action pressures cancel each other. The force required by the electromagnetic drive unit 21 for driving the valve body 15 may be a small electromagnetic force. Therefore, by inputting a very small variable power signal from the controller 30 to the flow rate variable valve 11 based on the signal from the tone signal generating means 31, it is possible to achieve a high-speed response and a rhythmic sense of the fluctuation cleaning device with low power consumption. Can be realized.

Further, the communication passage 22 also serves as one end of a configuration in which the flow variable valve 11 secures a minimum flow when the electromagnetic coil 23 is energized. That is, the electromagnetic coil 23 is energized,
When the flow control unit 16 of the valve body 15 closes the valve seat 17, the washing water from the inflow passage 12 passes through a certain gap between the outer diameter of the pressure balance unit 18 and the inner diameter of the cylinder unit 19, and further communicates with the communication passage. After that, it flows to the outflow path 13 and the cleaning nozzle 10. The fixed gap can ensure a minimum flow rate or more. As described above, the cleaning device of the present embodiment includes the tone signal generation means 31.
In addition to the function of automatically changing the flow rate ejected from the cleaning nozzle 10 in accordance with the signal of
When the power is not supplied or the maximum rated power is supplied, the flow path through which the flow rate is equal to or more than a predetermined minimum flow rate is secured, so that the electric signal to the flow rate changing means 11 changes at a high speed in response to a change in the musical tone. Even when changes rapidly,
The cleaning water spouting from the cleaning nozzle 10 can be changed without interrupting the flow. That is, the flow is not interrupted at the time of high-speed fluctuation cleaning, so that a water hammer action which causes a problem to the pump 2 and the tank 6 is not exerted. Therefore, it is possible to obtain an excellent cleaning device that enables the fluctuation cleaning with a sense of rhythm and that does not have a fear of shortening the life of the device due to the water hammer action by the fluctuation cleaning.
