It is what constitutes.

[0014]

According to the cleaning apparatus of the present invention, when the musical tone fluctuation cleaning mode A is selected and instructed, the musical tone signal generating means such as a compact disc player, a tape player, an audio reproducing element, a television, a radio, a cable broadcasting, etc. can generate music. -Music sounds such as river murmuring, wave sounds, and birds' voices are heard from a sounding body such as a speaker, and at the same time, the signal from the musical sound signal generating means is a musical sound such as pitch or loudness of the musical sound signal by the musical sound element extracting means. An element is extracted, and a variable power signal corresponding to the extracted musical tone element signal is output from the controller to the flow rate varying means. Therefore, the flow rate ejected from the cleaning nozzle automatically changes in response to the musical tone signal heard from the sounding body, enabling fluctuation cleaning with a sense of rhythm and comfortable cleaning with pleasure. Is.

Further, the cleaning apparatus of the present invention has the above-mentioned structure, and acts so as to automatically change the flow rate ejected from the cleaning nozzle according to the signal of the tone signal generating means.
The flow rate changing means has a structure in which a flow path that fully opens or flows a predetermined minimum flow rate or more is ensured when the current is not energized or when the maximum rated current is applied, so that the electric signal to the flow rate changing means changes at high speed in response to a change in musical tone. Even when the flow rate changes at high speed, the wash water ejected from the wash nozzle acts so as to change without interruption of the flow. Therefore, it is possible to perform fluctuation cleaning with a sense of rhythm, and to prevent a water hammer effect that shortens the life of the apparatus due to the fluctuation cleaning.

With the above-described structure of the cleaning apparatus of the present invention, the flow rate varying means is of the normally open type and is in the open state when not energized, and acts so that the flow rate is reduced only while energized. Here, even if the flow rate ejected from the cleaning nozzle can be changed rhythmically according to the signal of the tone signal generating means,
It has no meaning unless the original cleaning function is high. for that reason,
The change pattern of flow rate becomes important. For example, as for the time ratio between the time when the flow rate is fully opened and the time when the flow rate is throttled, it is desirable that the time during which a sufficient flow rate is secured is longer than the time during which the flow rate is throttled. In the cleaning device of the present invention, the flow rate varying means is energized from the controller at a pulse-like short energization time ratio in conjunction with the rhythm of the musical tone signal so that the flow rate of the cleaning water ejected from the cleaning nozzle is reduced in a pulsed manner. Act on. In other words, it works so as to realize comfortable fluctuation cleaning with a sense of rhythm and high cleaning effect with less power consumption. Further, even when abnormally high water pressure acts on the upstream side when the flow rate varying means is not energized, the flow rate varying means is a normally open type, so the abnormal high pressure causes the flow rate varying means to operate. It works by passing through and leaving the cleaning nozzle. In other words, it also acts to prevent damage to components upstream of the flow rate varying means (for example, a container such as a tank) and the flow rate varying means itself in the event of such an abnormality.

Further, according to the cleaning apparatus of the present invention, the inflow pressure of the flow rate variable valve acts on the flow rate control section and the pressure balance section of the valve body so that most of the respective working pressures cancel each other out. The force required by the electromagnetic drive unit that operates and drives the valve body is such that a slight electromagnetic force is sufficient. Therefore, by inputting a very small variable power signal from the controller to the flow rate variable valve based on the signal from the tone signal generating means, it is possible to realize a fluctuation cleaning device with high speed response and rhythm with low power consumption. It is a thing.

[0018]

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 showing an embodiment of the present invention. Water is pumped by a pump 2, passes through a water supply pipe 3, and a tank 6 equipped with a heater 4 and a temperature detector 5.
Leading to. Further, it flows from the tank 6 through the hot water supply pipe 7 to the inflow passage 12 of the flow rate variable valve 11 which is a flow rate varying means. Also,
The variable flow rate valve 11 includes a valve body 14 having an inflow path 12 and an outflow path 13, a valve body 15 provided in the valve body 14 for varying the flow rate, and a flow rate control unit 16 receiving the inflow pressure of the valve body 15. A corresponding valve seat 17, a cylinder part 19 for inwardly slidingly guiding a pressure balance part 18 that receives the inflow pressure of the valve body 15, and a flow rate control part 16 of the valve body 15 are urged in a direction away from the valve seat 17. Biasing means 20, an electromagnetic drive section 21 for exerting a force against the biasing force of the biasing section 20 in a direction to bring the valve element 15 closer to the valve seat 17, and a cylinder section 19
And a communication passage 22 that connects the outflow passage 13 to each other. Further, the electromagnetic drive unit 21 includes a fixed iron core 25 and a movable iron core 2 inside the electromagnetic coil 23 via a non-magnetic guide tube 24.
6, a yoke 27 and a yoke plate 28 are provided outside the electromagnetic coil 23. The valve element 15 and the movable iron core 26 are loosely attached.

Further, when the instruction input means 29 is instructed to select from a constant flow rate cleaning mode, a low speed beat cleaning mode, a high speed beat cleaning mode, a musical tone interlocking cleaning mode, etc., the variable power corresponding to the instruction of the instruction input means 29. Signal is controller 30
Is output to the electromagnetic drive unit 21 of the flow rate variable valve 11. For example, when the musical tone interlocking cleaning mode is instructed, the electric signal of the musical tone signal generating means 31 is heard as a sound signal from the speaker 32, which is a sounding body, and at the same time, the pitch and loudness of the musical tone signal from the musical tone signal generating means 31 or Musical sound element signals such as rhythmic elements are converted into musical sound element extraction 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 control means 11 in accordance with the musical tone element signal. Further, the method of extracting the rhythm element by the musical sound element extraction means 33 is such that a frequency filter focuses on the rhythm section of the musical tone signal, for example, the frequency band of the sound of a musical instrument such as a drum, and the current corresponding to the volume of the frequency band is extracted. Is amplified by the controller 30 and applied to the electromagnetic coil 23 of the flow rate varying means 11.

Next, a flow rate variable valve 11 which is a flow rate varying means.
Will be described in more detail. The electromagnetic drive unit 21 of the variable flow rate valve 11 is configured to move the movable iron core 2 according to the current flowing through the electromagnetic coil 23.
The power to suck 6 changes. That is, the force that pulls the valve body 15 against the force of the biasing means 20 changes according to the power signal input to the electromagnetic drive unit 21. That is, the electromagnetic drive unit 2
The flow rate can be changed by changing the current flowing to 1.
Further, when the valve body 15 is de-energized to the electromagnetic drive portion 21, the flow control portion 16 of the valve body 15 is urged by the urging means 20 to move away from the valve seat 17, and the flow passage is always opened to open the normally open valve. Is composed of. Further, the valve body 15 has a structure in which the fluid pressure from the inflow passage 12 is received by the flow rate control unit 16 and the pressure balance unit 18, and most of the working pressures of them are offset by each other. Therefore, a slight electromagnetic force of the electromagnetic drive unit 21 is sufficient to drive the valve body 15. Further, the characteristic of this valve is that a proper amount of water flows without completely closing the flow path even when it is fully closed. That is,
A current is passed through the electromagnetic drive unit 21 to control the flow rate control unit 1 of the valve body 15.
Even if the valve seat 6 fully closes the valve seat 17, it flows through a predetermined gap between the outer diameter of the pressure balance portion 18 and the inner diameter of the cylinder portion 9, and further through the communication passage 22 to the outflow passage 13.

Next, the operation of the above configuration will be described. When the user selects, for example, the musical tone fluctuation cleaning mode A by the instruction input means 29, the compact disc player
Musical sounds such as music, river murmuring, sound of waves, birds' voices, etc. from the musical sound signal generating means 31 of a tape player, an audio reproducing element, a television, a radio, a cable broadcasting, etc. are generated by a speaker 3 or the like.
2 from the musical tone signal generating means 31, the musical tone element extracting means 33 extracts musical tone elements such as pitch or loudness and rhythm element of the musical tone signal and responds to the extracted musical tone element signals. The variable power signal acts so as to be output from the controller 30 to the flow rate varying means 11. Therefore, the flow rate ejected from the cleaning nozzle 10 is
It acts so as to automatically change in response to the tone signal heard from the sounding body 32, so that fluctuation cleaning with a sense of rhythm and comfortable cleaning with fun can be performed.

When the user inputs the musical tone rhythm interlocking cleaning mode with the instruction inputting means 29, a musical tone signal is generated from the musical tone signal generating means 31 and music is heard from the sounding body 32, and at the same time, the rhythm of the music. The flow rate of the cleaning water ejected from the cleaning nozzle 10 changes in conjunction with. In the musical tone rhythm interlocking cleaning mode, the musical tone signal extracting means 33 extracts a rhythm element from the musical tone signal, and an electric output corresponding to the rhythm element signal is applied from the controller 30 to the electromagnetic coil 23 of the flow rate variable valve 11 to be energized. Caused by something. At this time, the state in which the input current applied from the controller 30 to the variable flow valve 11 changes and the state in which the wash water changes are shown in FIG. In this way, the flow rate 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. As described above, according to the sound intensity of the rhythm element that changes with time, the flow rate variable valve 11 is energized only at the moment of each signal, and the electromagnetic force generated in the electromagnetic coil 23 of the flow rate variable valve 11 causes the movable iron. Since the wick 26 acts so as to overcome the force of the means 20 for urging the valve body 15 to be drawn in, the instantaneous cleaning flow rate is reduced to the minimum flow rate. In addition, the input current from the controller 30 to the flow rate variable valve 11 stops between the pulses of the rhythm element signal, and the electromagnetic force of the electromagnetic coil 23 of the flow rate variable valve 11 disappears at that moment, so the valve body 18 is attached. The force of the urging means 20 causes it to fully open and immediately return to the maximum flow rate.

As described above, in the cleaning apparatus of this embodiment, the flow rate varying means 11 is of the normally open type and is in the open state when not energized, and acts so that the flow rate is reduced only while energized. Here, even if the flow rate ejected from the cleaning nozzle 10 can be changed rhythmically according to the signal of the musical tone signal generating means 31, it is meaningless if the original cleaning function is not high. Therefore, the change pattern of the flow rate is important. For example, as for the time ratio between the time when the flow rate is fully opened and the time when the flow rate is throttled, it is desirable that the time during which a sufficient flow rate is secured is longer than the time during which the flow rate is throttled. In the cleaning device of this embodiment, the flow rate of the cleaning water is pulsed from the cleaning nozzle 10 by the controller 30 energizing the flow rate varying means 11 at a short pulse-like energization time ratio in conjunction with the rhythm of the tone signal. Acts to be squeezed. In other words, it is possible to realize comfortable fluctuation cleaning with a sense of rhythm and high cleaning effect with less power consumption. Furthermore, if abnormally high water pressure acts on the upstream side when the flow rate varying means 11 is not energized, the flow rate varying means 11 is of the normally open type, so that the abnormal high pressure is It acts so as to pass through the variable flow rate valve 11 and exit from the cleaning nozzle 10. That is, at the time of such an abnormality, it is possible to prevent damage to components upstream of the flow rate varying means 11 (for example, the container such as the tank 6) and the flow rate varying means 11 itself.

In order to obtain the massage effect, if the flow rate varying means 11 for changing the flow rate ejected from the washing nozzle 10 in a pulsed manner is not provided as close to the washing nozzle 10 as possible, the effect will be reduced. Because, for example, tank 6
When provided upstream of the above, even if the flow rate changing means 11 changes the flow rate in a pulsed manner, the change becomes blunt due to the deformation and deformation of the container of the tank 6 and the like, and when jetted from the cleaning nozzle 10, it becomes a blunt change water flow, The massage effect is also reduced. That is, in a cleaning device for cleaning with a high massage effect, it is necessary to provide the flow rate varying means 11 in the vicinity of the cleaning nozzle 10. Therefore, it is an important point that the flow rate varying means 11 is configured to be a normally open type. Also, when performing constant flow rate cleaning without changing the flow rate, it is possible to save unnecessary power and time for energizing and opening the flow rate varying means 11.

A variable flow valve 11 which is a variable flow means.
Is the flow rate control unit 16 of the valve body 15 whose inflow pressure is from the inflow passage 12.
Also, the valve body pressure acting force due to the inflow pressure that acts on the pressure balance portion 18 is almost canceled out, and the valve is received only by the force of the biasing means 20, for example, the electromagnetic force of the electromagnetic drive portion 21 that can withstand about 100 grams. The structure capable of driving the body 15 enables lower power driving.

Here, the communication passage 22 is also important for reducing the valve body acting force of fluid pressure and for low power driving. This is because the communication passages 22 can communicate the back pressure chambers of the pressure balance unit 18 and the flow rate control unit 16, respectively, and this makes it possible to cancel the inflow pressure.

As described above, in the cleaning apparatus of this embodiment, the inflow pressure of the variable flow valve 11 acts on the flow rate control unit 16 and the pressure balance unit 18 of the valve body 15, and most of the working pressures of them are offset. Since they act so as to match each other, a small electromagnetic force may be used as the force required by the electromagnetic drive unit 21 that drives the valve body 15. 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 musical tone signal generating means 31, the fluctuation cleaning device having a high speed response and a sense of rhythm has low power consumption. Can be achieved with.

Further, the communication passage 22 also serves as one end of the structure in which the flow rate variable valve 11 ensures the minimum flow rate when the electromagnetic coil 23 is energized. That is, the electromagnetic coil 23 is energized,
When the flow rate control unit 16 of the valve body 15 closes the valve seat 17, the cleaning water from the inflow passage 12 passes through a fixed gap between the outer diameter of the pressure balance portion 18 and the inner diameter of the cylinder portion 19, and further the communication passage. It flows to the outflow path 13 and the cleaning nozzle 10 via 22. Due to the constant gap, a minimum flow rate or more can be secured. As described above, the cleaning device of the present embodiment has the musical tone signal generating means 31.
The flow rate changing means 11 operates so that the flow rate ejected from the cleaning nozzle 10 automatically changes according to the signal of
Is a structure in which a flow path that fully opens or flows at a predetermined minimum flow rate or more is secured during non-energization or maximum rated energization, whereby the electric signal to the flow rate varying means 11 changes at high speed in response to a change in musical tone, Even when changes rapidly
The cleaning water ejected from the cleaning nozzle 10 can change without interruption of the flow. In other words, the flow is not interrupted during high-speed fluctuation cleaning, so that no problematic water hammer action is exerted on the pump 2, the tank 6, and the like. Therefore, it is possible to obtain an excellent cleaning device which enables rhythmic cleaning with fluctuation and which does not have a fear of shortening the life of the device due to the water hammer effect.

[0030]

As described above, the cleaning apparatus of the present invention has the following effects. (1) By selecting and instructing the musical tone fluctuation cleaning mode by the instruction inputting means, music, river murmuring and waves are generated from the musical tone signal generating means such as a compact disc player, a tape player, an audio reproducing element, a television, a radio and a cable broadcasting. , The sound of a bird's voice, etc. is heard from a sounding body such as a speaker, and at the same time, the signal from the tone signal generating means is extracted by the tone element extracting means from the tone signal pitch or loudness elements such as loudness and rhythm elements. Then, since the changed power signal corresponding to the extracted musical tone element signal is output from the controller to the flow rate varying means, the flow rate ejected from the washing nozzle is automatically generated in correspondence with the musical tone signal heard from the sounding body. It is possible to perform fluctuation cleaning and enjoyable and comfortable cleaning with a sense of rhythm. (2) The flow rate ejected from the cleaning nozzle is automatically changed according to the signal of the musical tone signal generating means, and the cleaning water ejected from the cleaning nozzle flows when the flow rate varying means is in the non-energized state or the maximum rated energized state. Rhythmic high-speed fluctuation cleaning can be performed without being blocked, and the flow is not blocked, so it does not have a problematic water hammer effect on the pump, tank, etc., and enables fluctuation cleaning with a sense of rhythm, It is possible to obtain an excellent cleaning device that provides a more comfortable feeling than ever before and that does not worry about shortening the life of the device due to the water hammer effect. (3) Since the flow rate changing means is of the normally open type and is in the open state when not energized, and the flow rate is throttled only during energization, the pulse-like short energization time ratio is linked to the rhythm of the musical tone signal. By energizing the flow rate varying means from the controller with the controller, the flow rate of the washing water ejected from the washing nozzle can be instantaneously pulsed to provide comfortable fluctuation cleaning with a sense of rhythm and high cleaning effect with less power consumption. realizable.

Furthermore, even if abnormally high water pressure acts on the upstream side when the flow rate varying means is not energized, the flow rate varying means is of the normally open type.
The abnormal high pressure passes through the flow rate varying means and escapes from the cleaning nozzle, and at the time of such an abnormality, it is possible to prevent damage to components upstream of the flow rate varying means (for example, a container such as a tank) and the flow rate varying means itself. (4) Due to the structure in which the inflow pressure of the variable flow rate valve acts on the flow rate control unit and the pressure balance unit of the valve body, most of the working pressures of them act to cancel each other out, and the electromagnetic force that drives the valve body. The force required by the drive unit may be a small electromagnetic force, and a very small variable power signal is input from the controller to the flow rate variable valve based on the signal from the musical tone signal generating means, resulting in a high-speed response and a sense of rhythm. It is possible to realize a fluctuation cleaning device with low power consumption.
