A PWM (pulse width control) converter operating with a rectangular wave and a resonant converter operating with a sine wave are used. It can be divided into two types. If a resonance circuit (resonance coil and resonance capacitor) is added to the PWM converter, it easily derives from a resonance type converter.

As features of the electrolytic type submersible pump, the external air suction pipes that do not look good, the appearance is good because there is no wiring cord, etc., low frequency noise, electromagnetic vibration noise, resonance noise of the table, etc. Because it is running low, it does not hinder sleep.

The submersible pump has a built-in air / water detector so that it will not operate (e.g., electrolysis and propeller rotation) except in water. In addition, a water purifier (for example, bamboo charcoal, charcoal, Bincho charcoal, activated carbon) or the like may be incorporated. Further, a suction port may be provided slightly above so as not to suck the precipitate, or a filter, a strainer, or the like for preventing foreign matter from entering may be provided. Then, a display for displaying and / or alarming clogging of the filter or the like may be provided. An antibacterial treatment or the like is preferably applied to the external part (for example, a casing) in order to prevent sticking of water. Since there is no wiring code or the like, the submersible pump may be shaped like a rock or a volcano to increase the effect. In addition, it is interesting to add a playfulness and blink (red and yellow) the red and yellow LEDs at the crater. Also, if a jet port is provided on the side of the submersible pump body and jets intermittently, the water plants (imitation may be used) and the like are shaken and interesting.

There are two types of underwater lamps: one in which the entire aquarium shines, one in which the illumination effect is intended, for example, a flower-like glass fiber or the like or a glass fiber buried in imitation aquatic plants, or a goldfish. There is a spotlight type that follows a moving object. It is preferable to use an LED, a fluorescent lamp, an incandescent lamp, or the like as the underwater light. If the lens (transparent resin) portion is coated with titanium oxide as a photocatalyst or the like, the wettability of the water is improved, so that the lens is less likely to be stained.

As an incidental effect, water and oxygen are activated by magnetism (leakage alternating magnetic flux), and the animals (eg, goldfish, tropical fish, turtle) in the aquarium are activated, and turbidity (floating matter, etc.) due to the faeces of the animal is generated. ) Is reduced (the transparency is maintained in the water by the precipitation of foreign matter), the hardness (calciums) in the water is reduced (the transparency is maintained in the water by the precipitation of calcium), It comes alive, the smell decreases,
The flowers (petals) in the vase have a long life. or,
Since there is no wiring code, underwater lights (for example,
The illumination effect of the device in which the seven colors flicker in order and the device that repeats bright and dark lighting) is enhanced, and the effect of the room where the water tank, the vase, etc. are installed is increased.

The excitation coil buried in the pedestal for the aquarium apparatus of this embodiment is separated from the primary side circuit section and is insulated, so that it can be freely moved within the range of the bottom surface of the aquarium. Is what is being done. The moving method is, first, AC
When the plug is inserted into the AC outlet and the origin switch of the cradle is pressed, the primary circuit excites the excitation coil and starts a magnet-like action, so that the excitation coil moves to approximately the center of the front of the water tank. The submersible pump is put in the water tank to perform adsorption (operation such that magnets are attracted to each other). And
When the submersible pump is moved to an arbitrary position (the position is defined by the user), when the setting switch is pressed, the excitation coil is locked, the excitation coil is demagnetized, and power supply to the submersible pump is started. (However, it may not be activated by the detection signal of the air / water detector.) When the submersible pump is pulled out of the water for cleaning or the like, the primary side circuit unit stops power transmission and shifts to a standby state. (The AC plug may be removed from the AC outlet for cleaning. Even in this case, the position specified value set by operating the setting switch is stored.) The submersible pump is again placed on the excitation coil whose position is specified. When placed, the submersible pump is powered. However,
In the case of misalignment, the submersible pump may not operate. Therefore, when the cleaning complete switch is pressed, the excitation coil is temporarily unlocked, and fine movement (tracking) is performed so that the proximity to the induction coil is optimized. ) Is started, the excitation coil is locked at the optimum position, and power supply to the submersible pump is started.

Although not shown, as a second embodiment, a water tank apparatus according to one embodiment equipped with the switching power supply circuit will be described. A secondary circuit including an induction coil was insulated and buried in an artificial fish that swims on its own (it is equipped with a secondary battery, a control microcomputer, a driving device such as an electric motor, a magnet, etc.), and was used as a load device. The primary side circuit including the excitation coil is insulated, and the receiving basin of the water tank, the vase, etc.
An article such as a holder supported from the side may be used. )
When the remaining charged amount of the secondary battery in which the artificial fish is built reaches a specified value or less (for example, 1 Ah) and descends to the cradle side, the proximity of the artificial fish is detected (when the artificial fish is mounted on the artificial fish). The magnet that is present is detected by a magnetic detection device such as a Hall IC.)
To start supplying the power and the like required for charging (for example, + 3V1A), and the artificial fish has the charged amount equal to or more than a specified value (for example,
6Ah) and swim again by itself, the applied voltage or power consumption to be supplied to the artificial fish and supply (energization) so that the detachment of the artificial fish is detected and the supply of power and the like necessary for charging is stopped. An induction power supply control device for controlling time was used.
The aquarium apparatus according to the present embodiment is configured such that the switching power supply circuit is provided with five sets of excitation coils and a primary circuit section (for charging a submersible pump and / or a submersible lamp and / or a submersible heater and / or an artificial fish). is there.

Although not shown, as a third embodiment, the induction power supply control device according to one embodiment equipped with the switching power supply circuit integrally insulates a secondary circuit including an induction coil to completely waterproof the secondary circuit. A primary device including an exciting coil provided in a home health device (for example, a vibrator) inside the casing (inside a casing) or a power cable terminal portion of the home health device (preferably housed in a small case or the like). The circuit is integrally insulated, buried in a house wall (for example, a shower room), and the buried portion is made of a holder type decorative cover (particularly in shape, color, size, etc.) so that the power cable terminal portion can be hooked. ). The induction power supply control device of the present embodiment is obtained by providing four sets from one set of the excitation coil and the primary side circuit unit in the switching power supply circuit.

There is a type of holder type decorative cover that can surround the embedded portion from one port to four ports.
The holder type decorative cover may be designed to have a structure in which a power cable terminal of a home health device, which is a load device, can be hooked. However, small home health devices (for example, charging a vibrator, radios) may be directly ( A home health device, which is a load device that can receive power supply from the inductive power supply control device of the present embodiment, when it is formed into a shape that also serves as a cradle (holder) so that it can move away from and connect (without a power cable or the like). Types (power consumption equipment) can be increased.

Home health appliances, which are load devices that have been completely waterproofed, include, for example, a negative ion generating atomizer, an electrolysis-type weakly acidic electrolyzed water spouting shower device (hard water is removed and washed with water close to the pH value of the skin). Then, rough skin etc. may be improved.), Bath water circulation type purification device, bubble generator, human body part washer, vibrator (blood circulation promoting device), AC magnetic therapy device, mouth washer, coffee maker, Peltier Element type electronic refrigerator, ice machine, juicer / mixer, dryer, roller ball, dryer, low-speed fan for agitation, ventilation fan, pump, small simple washing machine, hot water washing toilet seat, radio TV (information display), PHS [Simplified mobile phone, transceiver or intercom-like applications],
And household electric appliances which can be driven at low voltage.

For reference, when using household electric appliances which can be driven at a low voltage in places where water is handled, special attention should be paid to electric shock. The danger is determined by the current flowing through the human body, and the magnitude of the voltage is secondary.
However, the lower the voltage (the contact voltage applied to the human body), the smaller the current flowing in the human body (equivalent resistance: 500Ω). Therefore, the following allowable contact voltage (as per the Japan Electric Association, Low Piezoelectric Ground Fault Protection Guidelines) is preferred. .) Should be adhered to. Class 1 contact state (most of the human body is in water)
, The voltage is 2.5 V or less, in the second type contact state (the state where the human body is extremely wet) is 25 V or less, and in the third type contact state (other than the above), the voltage is 50 V or less. In addition, a material having high insulation properties (for example, ABS resin) may be used to avoid exposure of metal parts to the external part (for example, casing), or watertightness (such as insulation treatment) may be improved.

In the insulation treatment of this embodiment, the printed circuit board on which the secondary circuit is mounted and the induction coil are integrally housed in a resin case or the like, and the printed circuit board on which the primary circuit is mounted and the excitation The coil is integrated and housed in a resin case, etc., and each is made of a potting material (for example, an electric insulating material such as urethane resin, polyester resin, epoxy resin, silicone resin, an adhesive sealing material, etc .; (Including those for anti-condensation materials and anti-condensation materials).

Although not shown, in the above-mentioned details, a plurality of magnets (or a magnetic field is generated by excitation and a magnetic field is generated by demagnetization) inside a home health device or a power cable terminal of the home health device as a load device. A coil that eliminates the magnetic field may be embedded), a plurality of magnetic detectors are embedded in the holder type decorative cover, and the type and / or power supply cable of the home health equipment are determined by a magnetic detection combination signal of the magnetic detector. In the terminal unit mounting and / or home health equipment body mounting and / or supply type request can be detected,
An applied voltage (regardless of DC voltage or AC voltage, or both may be applied) supplied by a control circuit such as a microcomputer employed in the primary circuit to the load device of the secondary circuit, or power consumption and supply (energization) Time (continuous supply, intermittent supply, specified time energization,
It doesn't matter if the power goes out at the designated time. ) To control.

For example, one magnet is buried in the power cable terminal of the electrolysis-type weak acidic electrolytic water spouting shower device (magnet presence = 1, magnet absence = 0, array is 001). For example, in a power cable terminal portion of a bath water circulation type purification device, two magnets are buried in parallel (serial, diagonal, horizontal, vertical) with an interval (magnet existence = 1, magnet absence = 0, The array is 101).
For example, in the main body of the vibrator, one magnet is embedded (magnet existence = 1, magnet absence = 0, array is 100). (In the home health device main body, a coil may be used instead of a magnet. A magnetic field is generated by excitation and the magnetic field is extinguished by demagnetization, so the load device of the secondary circuit (power consumption device, home health device) It can also be used as an applied voltage to be supplied to the power supply or a request signal for a supply format of power consumption.) In this way, if the method of embedding the magnets is devised, for example, the total number of magnetic detection devices mounted on the holder type decorative cover side 3
If there are three, three types (magnet existence = 1, magnet absence = 0,
The arrangement can identify the types of the home health devices (001, 100, 101). (In the present embodiment, a total of six Hall ICs are provided.) 000 in the arrangement indicates that the home health device body or the power cable terminal of the home health device as the load device is detached from the holder type decorative cover. ,
It is not used for detecting the type of home health equipment so that it can be detected and judged as "separated".

When the sequence 001 is detected, for example,
It is preferable to control to supply 40V2A power for only 5 minutes. When the array 101 is detected, for example, + 24V3
When the power of A is supplied indefinitely and the bath water circulation type purification device judges the turbidity and sterilization state of the bath water and stops the power consumption (detection of no current in the primary circuit and / or supply form of the secondary circuit) Request) and control to shift to the standby state.
When the array 101 is detected, for example, it is preferable to control to supply + 3V1A power for one hour. As described above, if the type and the like of the home health appliances, which are load devices, can be identified, the control of the switching power supply circuit (the process of giving control pulses to the switching elements Q51 and Q52) becomes easy, and the device is a load device. The life of home health appliances (for example, a power load itself such as a motor, a secondary battery, and the like) can be improved to extend the life.

As described above, various combinations and the like have been described with respect to the preferred embodiments of the present invention. However, the present invention is not limited to the above-described embodiments, and a number of combinations are possible without departing from the spirit of the invention. Needless to say, combinations, modifications and the like can be made.
