Description of the Related Art Electric appliances having a DC device and an AC device include a local washing device for discharging washing water to a local part of a human body and washing the same, and a tableware in a container by jetting the washing water into a closed container. There is a dishwasher for washing dishes. For example, in the local cleaning device, a hot water heater for warming the flush water, a hot air heater for hot air drying, a toilet seat heater for heating a toilet seat, and the like are provided as AC devices that receive an AC. Further, the water discharge nozzle of the washing water is driven forward and backward, and the fan for blowing hot air is rotated. However, the nozzle motor and the fan motor which are the driving source do not need to be operated under an excessive load environment. Therefore, these motors are DC devices that receive DC.

[0003]

In a local cleaning apparatus having such a device configuration, a power supply circuit board for applying a direct current and an alternating current is provided in a main body of the apparatus together with a heater control board, a motor control board, and the like. However, the following problems were pointed out. First, since the number of components to be installed in the main body increases, the miniaturization, thinning, or weight reduction of the local cleaning device itself is hindered. In addition, since the area where the local cleaning device has spread is expanding, the heater and its control equipment are designed and designed according to the specifications according to the AC power supply voltage in the installation area, for example, about 100 V in Japan and about 240 V in Europe and the United States. Had to be manufactured. For this reason, it is necessary to prepare various heaters and control devices and change the specifications in accordance with the AC power source at the shipping destination, which is complicated. Furthermore, the heat generated during the conversion from AC to DC in the power supply circuit board increases the temperature of the installation location of the heater control board and the like, so measures to prevent malfunction due to heat, such as heat resistance of the electronic device itself used, It is necessary to improve the performance, install cooling equipment, change the design of equipment layout, and so on. Please note that these issues are
The present invention is not limited to the local cleaning device, but exists in other electric devices such as a dishwashing device having a DC device and an AC device.

[0004] By the way, for example, a battery-driven electric device such as a cassette tape recorder is provided with a DC conversion adapter separately from a main body so that the electric device can be used from an AC outlet of a general household. However, in these battery-driven electric devices, only DC devices such as motors need to be used, and the total applied DC power is only tens of W at most. Therefore, in an electric device such as a local cleaning device that requires several hundreds of watts of electric power (heater power) in which a direct current device and an alternating current device are mixed, a conversion adapter that suffices to perform only DC conversion cannot be applied as it is. Was.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to reduce the size and standardize the specifications of electric equipment having DC equipment and AC equipment, and to avoid problems associated with DC conversion. .

[0006]

Means for Solving the Problems and Action / Effect thereof To solve at least a part of the problems, the power supply device of the present invention is applied to an electric device in which a DC device and an AC device operating at a predetermined voltage are mixed. A power supply device for supplying electric power, the power supply device being provided separately from a connection unit connected to a commercial power supply and the electric device, and converting an alternating current of the commercial power supply input from the connection unit into a DC of the predetermined voltage. A power supply unit for supplying the AC of the commercial power supply as the AC of the predetermined voltage, and supplying the DC voltage and the AC voltage obtained by the power supply unit to the DC device and the AC device of the electric device, respectively. And a power supply line for performing the operation.

In the power supply device of the present invention having the above configuration,
DC and AC of a predetermined voltage required for operating the DC device and the AC device of the electric device are supplied from the power supply device which is configured separately from the electric device. Therefore, it is not necessary to dispose a device for obtaining the AC / DC power supply on the side of the electric device, so that the size of the electric device itself can be reduced. Also,
On the power supply side, heat is generated during DC conversion,
The influence of the heat can be prevented from being exerted on the side of the electric device which is configured separately from the power supply device. Therefore, no special measures are required on the electrical device side to prevent malfunction due to heat, so that the device configuration can be simplified and the flexibility of the device layout can be improved. In addition, since a predetermined voltage of DC or AC is applied to the DC device and the AC device of the electric device from the power supply device configured separately from the electric device through the DC and AC power supply lines, the electric device is connected to the DC device. The specifications of the AC equipment can be unified for each of the predetermined voltages.

[0008] The power supply device of the present invention having the above-described structure is as follows.
The following modes can be adopted. That is, a housing for accommodating the power supply unit may be provided, and the housing may integrally include the connection unit. With this configuration, the power supply device itself can be positioned in a state where it is connected to the commercial power supply via its housing, so that space can be saved before installing the power supply device. In addition, since the commercial power supply is generally separated from the floor surface, the power supply device can be prevented from coming into contact with water leaking to the floor, which is preferable from the viewpoint of avoiding electric leakage and the like.

Further, the power supply unit may have a function of converting an AC of the commercial power supply into an AC of the predetermined voltage. With this configuration, an AC of a predetermined voltage can be obtained regardless of a standard value of an AC voltage of a commercial power supply in an installation area of an electric device that receives power supply from the power supply device of the present invention, and the AC device can be used without any trouble. . Therefore,
The application area of the power supply device and the installation area of the electric equipment can be expanded, and the installation work of the electric equipment can be simplified.

When the power supply unit detects a leakage,
The apparatus may include a power supply cutoff unit that blocks power supply to the DC device and the AC device. By doing so, power is not carelessly supplied while the electric leakage is occurring, so that a problem due to the electric leakage can be reliably avoided. In this case, it is preferable to provide a leak notification unit such as a lamp, an LED, or an audio notification device that displays a notification when a leak is detected.
It is to be noted that the electric leakage notification means may be provided on the electric device side. Further, it is preferable to provide an energization resetting means (an energization reset switch or the like) for re-establishing the application of the electric power interrupted by the leakage detection.

[0011] The power supply cutoff unit may be configured to cut off the DC power supply and the AC power supply to the DC device and the AC device independently or synchronously. In order to do this, a switch is provided to forcibly stop power supply to DC devices and AC devices regardless of the presence or absence of leakage, and by operating this switch, DC power supply and AC power supply can be cut off independently,
What is necessary is just to comprise so that it may shut off synchronously. This way,
Power supply can be forcibly stopped at the time of installation work of electric equipment or at the time of maintenance and inspection, so that these works can be easily performed. At this time, a lamp, an LED, or the like that is turned on when power is applied along with power supply may be provided in the power supply device. In this way, the state of power application (power supply state) can be checked during the installation work of the electrical equipment, maintenance and inspection, and the like, so that these works can be performed easily.

Further, the power supply unit may have an abnormality detection cutoff unit that shuts off power supply to the DC device and the AC device when a power supply abnormality that may cause an operation abnormality of the electric device is detected. . With this configuration, power supply is not performed carelessly in a state where the power supply abnormality has occurred, so that an operation abnormality of the electric device can be avoided.

[0013] Also, a detection circuit for inputting a signal indicating an operation state of the electric device from the electric device side and detecting the operation state is provided to the power supply unit; And / or a voltage adjusting circuit for adjusting the output of the AC voltage. In this case, a detection circuit may be superimposed on the power supply line to input the signal from the electric device side and detect the operation state. With this configuration, the output of the DC voltage and / or the AC voltage is adjusted according to the detected operation state of the electric device, so that the DC device and the AC device of the electric device can be suitably operated.

Further, the power supply unit may include a zero-cross detection circuit for detecting a sign inversion of an AC voltage, and transmit a detection result to a control device of the AC device in the electric device via a signal line. . This way,
Since the control device of the AC device on the side of the electric device can recognize the frequency of the AC applied to the AC device from the zero-cross detection result, it is possible to optimize the energization timing when controlling the AC device according to the characteristics of the AC device. . For example, the control angle α during the phase control can be optimized according to the characteristics of the AC device.

Further, the power supply unit may have a conversion circuit for converting a plurality of DCs of a rated voltage. With this configuration, the DC device provided in the electric device can be variously selected according to the purpose, so that the added value of the electric device can be increased. Specifically, since various types of motors can be selected, it is possible to diversify the driving speed of the object to be driven by the motors.

[0016] Further, the housing for accommodating the power supply unit may have an opening for ventilating the inside and outside. In this case, heat generated by power supply and current conversion can be radiated from the opening to prevent heat storage inside the housing. At this time, it is preferable to provide the opening on the side surface or the bottom surface of the housing because it is easy to prevent inadvertent entry of dust and water droplets.

[0017] The connection portion may include a pair of plugs inserted into a commercial power outlet. In this case, the power supply device itself is located directly connected to the commercial power outlet, so that space can be saved. Moreover, since the commercial power outlet is generally distant from the floor, the power supply unit can be prevented from coming into contact with water leaking to the floor, which is preferable from the viewpoint of avoiding leakage.

At this time, the connecting portion is provided for ground wiring of the AC equipment, and is provided with a ground plug which enters a ground terminal of the commercial power outlet having a three-terminal structure. The terminal structure may be configured to change its protruding posture from the connection portion so as not to be an obstacle when being plugged into the commercial power outlet. For example, the ground plug may be rotatable. With this configuration, the connection portion can be directly connected to the commercial power outlet regardless of whether the commercial power outlet has a two-terminal structure assuming insertion of a pair of plugs or a three-terminal structure having a ground terminal. In other words, when the commercial power outlet has a two-terminal structure, only the pair of plugs are inserted into the commercial power outlet having the two-terminal structure in a state where the protruding posture is changed by rotating the earth plug and the like, and the connection is established. Can be connected directly to a commercial power outlet.
If the commercial power outlet has a three-terminal structure, a pair of plugs and a grounding plug can be inserted into each terminal, and the connection portion can be directly connected to the commercial power outlet. Therefore, a so-called 3P conversion plug having a ground wire is not required.

Further, a part of the earth plug is exposed to the outside when the projecting posture is changed so that the pair of plugs does not become an obstacle when being inserted into the commercial power outlet having a two-terminal structure. be able to. In this case, the ground wire can be connected to the ground plug at the portion exposed to the outside, and the ground can be taken with the ground wire.

According to another aspect of the present invention, there is provided an electric device including a DC device operating at a predetermined voltage and an AC device, wherein the DC device is connected to the AC device. A main unit in which the device is installed, and each of the power supply devices described above is provided separately from the main unit, and the power supply unit is connected to the DC device and the AC device via the power supply line. It is characterized by the following.

In the electric device of the present invention having the above configuration,
A power supply device for obtaining DC / AC of a predetermined voltage to be applied to a DC device and an AC device is separate from a main body having the DC device and the AC device. Therefore, it is not necessary to dispose a device for obtaining a power supply in the main body, and the main body, and hence the electric device itself, can be reduced in size. Further, since the power supply device and the main body are separate bodies, it is possible to prevent the influence of heat at the time of DC conversion from exerting on the main body from the power supply device. Therefore, no special measures are required on the electrical device side to prevent malfunction due to heat, and the device configuration can be simplified and the flexibility of device layout can be improved.
In addition, since a predetermined voltage of DC or AC is applied to the DC device and the AC device of the main unit from the power supply device separate from the main unit and to the DC and AC power supply lines, the main unit is connected to the DC device. The specifications of the equipment can be unified for each predetermined voltage.

The electric device may have at least one of the DC device and the AC device as a plumbing device. In such an electric device, a short circuit is likely to occur in the plumbing device. This is preferable because troubles in the case of occurrence can be reliably avoided. In addition, when the plumbing device is an AC device (specifically, a heater) for raising the temperature of water, conventionally, it is necessary to adjust the heater specification each time according to the commercial power supply voltage in the installation area. According to the present invention, the heater specifications can be unified as described above, which is preferable.

A part of the cover is a light transmitting window 29a that is colored so as to selectively transmit light from a seating sensor (see FIG. 2) for detecting a seated human body. A minimum button required for local cleaning is provided below the cover of the sleeve 22 so that even when the remote operation device 14 cannot be operated due to a battery exhaustion or the like, the sleeve 2 cannot be operated.
Local cleaning can be performed by operating the button 2.

Next, the functional components of the local cleaning device 10 of this embodiment will be described. As shown in FIG. 2, the local cleaning apparatus 10 includes a control board 30 for driving and controlling various functional components. The control board 30 includes the main body 1

In this case, the types of load devices included in the group of AC load devices 35 and the group of DC load devices 37 are determined by the basic functions and additional functions of the local cleaning device 10. The basic functions include a hot water function for preheating the water so as not to discharge the cleaning water to the local area, a drying function for drying the local area with hot air, and the cleaning nozzle 24 from the standby position in the main body section. In addition to a nozzle advancing / retreating function for advancing / retreating to a front washing position, there is a water supply function for supplying / stopping washing water via opening / closing of a washing water system pipe line. The additional functions are variously selected according to the request of the device purchaser, and include a function of heating the toilet seat, a display function of displaying an operation state of the local cleaning device, and removing an odor in the bowl portion of the toilet bowl. It has a deodorizing function. It is needless to say that the toilet seat heating function and the deodorizing function may be the basic functions.

For example, if the local cleaning device 10 has a toilet seat heating function and a display function in addition to the basic functions described above, the function realizing equipment necessary for realizing these functions is the main unit 1.
2, the function implementing devices are classified into the AC load device group 35 or the DC load device group 37, respectively. In this case, a hot water heater for hot water washing, a hot air heater for hot air drying, a toilet seat heater for toilet seat heating, a solenoid valve for pipe opening and closing, and the like are included in the AC load device group 35. The toilet seat heater is disposed on the toilet seat 18 and the others are disposed at predetermined positions in the main body. Each of the heaters divided into the AC load equipment group 35 consumes a large amount of power of several hundred W, and is connected to the power supply unit 16 via the ground line 16c in order to avoid trouble due to careless leakage. Have been.

Further, in addition to a nozzle motor for moving the nozzle forward and backward, a fan motor for blowing hot air, a seating sensor for detecting seating on a toilet seat, and a water inlet for obtaining control parameters for warming the washing water. Various sensors such as a water discharge temperature sensor and various display lamps are divided into a group of DC load devices 37, which are arranged at predetermined positions in the main body. The signals from the various sensors are input to the control circuit 32. Therefore, the above-described function realizing device such as a hot water heater or a nozzle motor corresponds to the “DC device and AC device” of the present invention. The AC load drive circuit 34 and the DC load drive circuit 36 are provided on the same substrate with drive circuits for the various load devices (function realizing devices) included in the AC load device group 35 or the DC load device group 37, respectively. The drive circuit for each load device drives and controls each load device according to a control signal from the control circuit 32.

In this embodiment, a connector (not shown) is provided at an end of the control board 30 having the above-described configuration, and the control board 30 and the power supply unit 16 are electrically connected via the connector. In addition, the control board 30 was obtained by molding the above-described circuits and the power supply lines and the like on the board with a resin together with its constituent electronic devices. Therefore, even if dew condensation occurs inside the main body 12 due to a decrease in the outside air temperature or water for cleaning enters the main body, the water is supplied to the control board 30.
Because it does not touch the circuit configuration devices and wiring in
Problems such as short circuits and malfunctions can be avoided.

Here, the driving state of the above-described load device will be described in relation to a cleaning operation, a drying operation, and the like corresponding to a button operation of the remote control device 14 and the sleeve portion 22. When a remote control device 14 or a cleaning button on the sleeve 22, for example, a bottom cleaning button, is operated, the control circuit 32 outputs a nozzle advance signal to the DC load driving circuit 36. DC load drive circuit 3
Specifically, in No. 6, the nozzle drive circuit applies a predetermined DC rated voltage to the nozzle motor and controls the normal rotation drive of the motor. Thereby, the cleaning nozzle 24 advances from the standby position in the main body to the buttocks cleaning position. In addition, it is also possible to supply water to the nozzles prior to such advance of the nozzles and to wash the area around the water discharge holes of the nozzles. When the advance of the nozzle is completed, the control circuit 32 outputs a water supply signal to the AC load drive circuit 34. In the AC load drive circuit 34, specifically, the solenoid valve drive circuit applies a predetermined AC rated voltage to the solenoid valve, and controls the solenoid valve to open the line. This allows
Cleaning water is supplied to the cleaning nozzle 24 at the cleaning position (the butt cleaning position), and the cleaning water is discharged from the discharge hole.

In this case, when the user is seated on the toilet seat 18 and the seating sensor is turned on, the control circuit 32 receives the ON signal and outputs an ON signal of the hot water heater to the AC load driving circuit 34. Have been. At this time, the control circuit 32 determines the necessary power supply to the hot water heater based on the washing water temperature from the incoming / outgoing water temperature sensor and the set hot water temperature, and determines the result together with the heater ON signal as described above.

In response to this signal, a predetermined AC rated voltage is applied to the hot water heater to control the energization of the heater. Thus, the cleaning water is warmed in advance before the cleaning nozzle 24 advances.

Thereafter, when the stop button is operated, the control circuit 32 causes the AC load drive circuit 34 (electromagnetic valve drive circuit) to operate.
The AC load drive circuit 34 (electromagnetic valve drive circuit) receives this signal and stops applying voltage to the electromagnetic valve, thereby controlling the electromagnetic valve to close the pipeline. As a result, the discharge of the cleaning water from the cleaning nozzle 24 is stopped. Next, the control circuit 32 controls the DC load driving circuit 36 (nozzle driving circuit).
And a DC load drive circuit 36 (nozzle drive circuit) applies a DC voltage to the nozzle motor to control the reverse rotation of the nozzle motor. Thus, the cleaning nozzle 24 returns from the cleaning position to the standby position in the main body.
After returning to the nozzle, water may be supplied to the nozzle to clean the area around the water discharge hole of the nozzle.

That is, at least in each of the load devices included in the DC load device group 37, the power supply circuit of the power supply unit 16 is configured according to the AC outlet voltage without changing the required rated voltage value. In addition, it is possible to perform AC power supply at a rated voltage and DC power supply at a rated voltage.

More specifically, the AC load equipment group 35
The rated voltage of the load equipment is 100 V AC, the load equipment of the DC load equipment group 37 and the rated voltage of the control circuit 32 are DC 2
4V and the AC outlet voltage (power supply voltage) is about 10
If the voltage is 0 to 110 V (frequency: 50 Hz), the first to fourth power supply circuits required to obtain an AC having a rated voltage of 100 V and a DC having a rated voltage of 24 V from the AC (about 100 to 110 V) of the AC outlet. The device and the circuit configuration are determined. On the other hand, the rating of the DC load device is as described above, and the AC outlet voltage is approximately 200 to 240V.
Then, the first voltage required to obtain a DC voltage of 24V
In addition, the constituent devices and the circuit configuration of the fourth power supply circuit are determined, and the rated voltage of the load devices of the AC load device group 35 is set to the same AC specification as the above-mentioned AC outlet voltage so that the AC of this voltage value can be obtained. Circuit configuration and the like. As a result, the specifications of the load devices included in the DC load device group 37 can be unified on the main body 12 side regardless of the AC outlet voltage. In addition, the specifications of the control board 30 for controlling these load devices, such as the DC-related circuit configuration, can be unified. Therefore, it is possible to simplify the management of the manufacturing process of the main body 12 and to unify the components, thereby providing manufacturing advantages such as a reduction in manufacturing cost and an improvement in productivity. And for AC load equipment,
It only needs to be adapted to the AC outlet voltage at the installation site. In addition, in order to unify the specifications of AC load devices and AC-related circuit configurations, a transformer for transforming the AC outlet voltage to a predetermined AC rated voltage (for example, 100 V) is installed in accordance with the AC outlet voltage at the installation location. do it. Specifically, if the rated voltage of the AC load device is 100
V, and if the installation AC outlet voltage is different from this rated voltage, a transformer may be installed. This makes it possible to unify the specifications of the AC load device and the AC-related circuit configuration and the like, thereby increasing manufacturing advantages such as reduction in manufacturing cost and improvement in productivity.

The fact that the specifications of the load devices can be unified on the side of the main body 12 in this manner also has an advantage for the power supply unit 16. In other words, the main unit 1
2 even if the existing power supply unit 16 is replaced.
Has the advantage that it can be used as is. Further, in recycling the discarded local cleaning device 10, the main body 12
Each functional device (load device) installed in the power supply unit is disassembled and collected and reused, and the power supply unit 16 has an advantage that it can be reused in units of this unit.

The power supply unit 16 for obtaining DC / AC of a rated voltage applied to each load device included in the AC load device group 35 and the DC load device group 37 is provided separately from the main body 12. For this reason, it is not necessary to incorporate a power supply voltage generating member for applying to each of the above-mentioned load devices in the main body 12 at all, so that the size of the main body 12 and thus the local cleaning device 10 is reduced. be able to. In addition, the number of members arranged inside the main body 12 is reduced, so that the main body 12 can be made thinner and lighter, and the work load at the time of installation work on the toilet and attaching / detaching work of the main body at the time of maintenance / inspection. Can be reduced.

Further, since the power supply unit 16 is separate from the main body 12, the power supply unit 1 is not required for DC conversion.
The heat generated in 6 can hardly be transmitted to the main body 12. For this reason, it is not necessary to take any special measures for preventing malfunctions due to heat with respect to the circuit components of the control board 30 disposed in the main body 12, and it is possible to simplify the device configuration and improve the degree of freedom in the device layout. it can.

Further, the above-described local cleaning apparatus 1 of the present embodiment
According to 0, there are the following advantages. Since the power leakage detection circuit and the power cutoff circuit are incorporated in the power supply unit 16, it is possible to prevent the power supply from being performed carelessly while the leakage occurs. As a result, it is possible to reliably avoid the trouble due to the electric leakage. When the leakage is detected, the leakage indicator lamp 45 is turned on to notify the occurrence of the leakage, so that it is easy to take a measure for extinguishing the leakage. After the cause of the leakage is eliminated, the power application can be restarted by operating the power return switch 47. Since the power supply switch is forcibly stopped by shutting off the circuit irrespective of the presence or absence of the leakage by the power supply stop switch 48, the work of installing the local cleaning device 10 and the maintenance and inspection work can be reliably performed in a power-off state, which is preferable. . Also, the power indicator light 46
Thus, the energized / non-energized state can be visually recognized, so that the above-described operation can be reliably performed while the power is turned off.

The unit housing 17 of the power supply unit 16 has a side opening 42 and a bottom opening 44 on the left and right side surfaces and the bottom surface.
And the inside and outside of the power supply unit 16 are ventilated through these openings. Therefore, heat generated during DC conversion or the like can be radiated from these openings to prevent heat storage inside the power supply unit 16. In addition, since these openings are provided on the side and bottom surfaces of the housing, dust and water droplets can be prevented from inadvertently entering from the openings, which is preferable. In addition, in the present embodiment, the dustproof eaves 43 inclined outward are provided in each of the side openings 42, so that the ingress of dust, water droplets, and the like can be more reliably prevented. The power supply unit 16 is capable of inserting the plug 40 and the earth plug 41 into an AC outlet having a three-terminal structure and stopping the AC outlet. Therefore, it is not necessary to take a special space for installing the power supply unit around the toilet, and the space around the toilet can be saved accordingly. In addition, since the power supply unit 16 is placed at the AC outlet position away from the floor, even if water is collected on the floor of the toilet due to cleaning of the toilet or the like, the power supply unit 1 is stored in the water.
6 can be prevented from contacting, and this is preferable from the viewpoint of avoiding leakage. The power supply unit 16 can be replaced according to the specification of the power supply voltage at the place where the local cleaning device 10 is installed. For example, the local cleaning device 10 for an area having a power supply voltage of about 100 to 110 V includes:
A power supply unit 16 having a circuit configuration necessary for obtaining an AC having a rated voltage of 100 V and a DC having a rated voltage of 24 V from this power supply voltage may be mounted. On the other hand, when the power supply voltage is about 200
The local cleaning device 10 for a region of up to 240 V has an AC having a rated voltage of 100 V and a rated voltage of 24
A power supply unit 16 having a circuit configuration necessary to obtain V DC may be mounted. For this reason, by using the power supply unit 16 according to the power supply voltage, the local cleaning device can be easily applied and installed in regions having various power supply voltages.

Power can be supplied to the load devices included in 37. Moreover, when the power supply unit 16 is connected to an AC outlet having a two-terminal structure, the grounding plug 41 is exposed to the outside.
A ground wire can be connected to a to ground the AC load equipment. Therefore, a so-called 3P conversion plug is not required for connecting to a two-terminal AC outlet having no ground terminal.

As a modified example of the ground plug 41, the ground plug 41 can be configured to be able to advance and retreat inside the unit housing 17, so that it can take an advancing and protruding posture and a retracted posture in the housing. If the housing is provided with a cutout or the like so that the tip of the earth plug 41 in the evacuation position is exposed to the outside even when the evacuation is performed, the ground can be obtained by connecting the earth wire.

In this case, the configuration in which the ground plug 41 can be rotated and retracted from the protruding position as described above can be applied not only to the local cleaning device 10 but also to various types. For example, the present invention can be applied to an alternating current (AC) driven electric device and an AC power cord connected thereto as follows. That is, an AC power cord, which is provided with a pair of plugs protruding into an AC outlet (commercial power outlet) protrudingly provided with a ground plug protruding into a ground terminal of the AC outlet having a three-terminal structure.

1b may be made to freely advance or bendable from the plug portion 71. According to the AC power cord 70, regardless of whether the AC outlet has a two-terminal structure or a three-terminal structure, power can be supplied to an electric device such as a printer, a copying machine, or a microwave oven as described above. These devices can be grounded without any trouble. Moreover, it is not necessary to use a 3P plug that is necessary when connecting these electric devices to an AC outlet having a two-terminal structure. In addition, even when an electric device such as a printer, a copying machine, and a microwave oven has an AC power cord already connected to the main body of the device, the plug structure described above can be employed instead of the AC power cord alone. The same effects can be obtained with these electric devices.

In this modification, when AC power or DC power is supplied to the AC load device or the DC load device on the side of the main body 12, respectively, the AC power supply and the DC power supply can be forcibly cut off independently. Therefore, when there is an abnormality in one of the AC load device and the DC load device, the power supply to the corresponding load device is cut off, and the replacement, maintenance, and the like of these devices can be easily performed. In addition, power supply can be stopped when there is an abnormality in the load device, so that power supply is not continued in a state where the abnormality remains. Therefore, it is possible to avoid device damage beforehand and to reduce the degree of damage. In addition, AC power supply and DC power supply can be cut off independently,

The power supply cutoff circuit is configured so that the AC power supply and the DC power supply, which have been cut off once, are synchronously restored by operating the power supply return switch 47 described above. Even in this modified example, as described above, the input means 65 can be configured as a switch operated by the user or can be configured by the control circuit 32.

In this modification, the AC power supply and the DC power supply to the AC load device and the DC load device on the side of the main body 12 can be forcibly shut off synchronously. Therefore, when there is an abnormality in one of the AC load device and the DC load device, the power supply to all the load devices is cut off, and the replacement, maintenance and inspection of these devices can be easily performed. In addition, if there is an abnormality in the load device, AC and DC power supply can be stopped synchronously, so that power supply is not continued in the state where the abnormality remains, which is useful for avoiding device damage and reducing the degree of damage. .
