Abstract

PURPOSE:To control consumption power by permitting a control means to hold DC power source, to release the action of a current holding part through an output part by means of the prescribed input of a first input part and to interrupt the DC power source when the action of a second input part impresses an AC power source on the control means for the first time. CONSTITUTION:The AC power source is impressed on a rectifier smoothing part 4 for the first time through a transformer part 3 by the action of the second input part 9, and the DC power source 1 which can be obtained by rectifying and smoothing the AC power source in the rectifier smoothing part 4 is supplied to the control means 5'. The control means 5' operates the power holding part 10 through an output part 7, holds the DC power source 1, and a system comes to a setting-waiting state by the input part 8 of a user. The control means 5' releases the action of the power holding part 10 by the prescribed input of the first input part 8 through the output part 7 and interrupts the DC power source. Thus, consumption power is cut in the control means 5', and consumption power as a heating apparatus can be controlled in a period when the user waits for the setting of the heating apparatus.

Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Application Field No. 11 relates to heating equipment controlled by a control means constituted by a microcomputer.

Conventional technology Conventionally, heating equipment controlled by the microcomputer described above first uses AC! The DC power obtained by rectifying and smoothing the AC power is supplied to the microcomputer and peripheral parts, and the user can make settings at any time.The user then makes the desired settings and starts heating. operating the equipment.

The configuration of a conventional heating device will be explained based on the block diagram of FIG. 3.

In FIG. 3, l is a commercial frequency AC power supply, and this AC power supply 1 includes a heating unit 2 consisting of a switching contact 2A such as a relay and a heating unit 2i3 connected in series. , a transformer section 3 comprising a transformer 3A and transforming the AC vL source 1 are connected in parallel. One side of the primary side and the secondary side of this transformer section 3 are connected, and a rectifier and smoother section 4 that rectifies and smoothes the output (AC voltage) of the transformer section 3 is connected to the secondary side of the transformer section 3. . The output of this rectifying and smoothing unit 4, that is, the DC power obtained by rectifying and smoothing the AC power supply 1, is connected to a microcomputer 5 that processes user settings and outputs a predetermined output, and a microcomputer 5 that processes settings etc. of the user and outputs a predetermined output. When microcomputer 5
a reset unit 6 that initializes the microcomputer 5;
The output opens and closes the opening/closing contact 2A of the heating section 2, and the LED
? Consisting of an output section 7 that turns on and off the light A, alarms with a buzzer 7B, etc., and switches 88 to 8D, each of which is connected to an input section 8 that makes desired settings for the microcomputer 5, and supplies wt power supply voltage. It is carried out.

The operation of the heating device configured as described above will be explained below.

Interact now! When the source l is applied, the voltage is transformed by the transformer 3 and the rectifier and smoother 4, and the DC power obtained by rectifying and smoothing is supplied to the microcomputer 5, the input part 8, the output part 7, and the reset part 6, and is reset. Since the section 6 initializes the microcomputer 5 when the voltage of the DC power supply is below a predetermined voltage, when the voltage becomes stable (becomes a steady voltage),
The microcomputer 5 is initialized and waits for the user's settings.

Next, when the user makes a desired setting using the input section 8, the microcomputer 5 outputs a drive signal to the output section 7 according to the setting, and two contacts close in response to the output signal from the output section 7. The heating unit 2 is driven, or a notification is given by a display buzzer 7B using an LED 7A.

Problems to be Solved by the Invention However, in the above-mentioned conventional configuration, DC power is constantly applied to the microcomputer 5 etc. during the period of waiting for the user's settings, so power is wasted during that period. For example, in a stationary (built-in) type that is semi-permanently connected to an AC power source, there is a problem in that power is constantly consumed.

The present invention solves the above problems, and aims to provide a heating device that can minimize power consumption until the user makes desired settings.

Means for Solving the Problems In order to solve the above problems, the present invention provides a transformer section connected in parallel with an AC power source together with a heating section, and a rectifying and smoothing section connected to the transformer section. The control means includes a control means connected to a first input section for setting, and an output section operated by the output of the control means, and the control means controls the output section by a predetermined input of the first input section. A heating device in which the alternating current power source is turned on and off to the heating section through A second input section and a power supply holding section operated by the output section are connected in parallel to one of the two,
When the DC power is supplied to the control means by the operation of the second input unit, after a predetermined time, the power supply holding unit is operated via the output unit to hold the DC power;
A function has been added to interrupt the DC power supply by canceling the operation of the power supply holding section via the output section after a predetermined time with a predetermined input from the first input section.

Effect With the above configuration, AC power is first applied to the rectifying and smoothing section through the transformer when the second input section operates, and the DC power obtained by rectifying and smoothing the AC power in the rectifying and smoothing section is supplied to the control means. Then, the control means operates the power supply holding section via the output section to hold the DC power, and waits for the setting by the user's first input section. Further, the control means releases the operation of the power supply holding section via the output section in response to a predetermined input from the input section of WXl, thereby cutting off the DC power supply. Therefore, while waiting for the user to set the heating device (until the user makes the desired settings), the power consumption of the control means is cut, and the power consumption of the heating device is minimized.

Example An embodiment of the present invention will be described below based on the drawings.

FIG. 1 is a block diagram of a heating device showing an embodiment of the present invention. Note that the same components as in FIG. 3 of the conventional example are given the same reference numerals, and explanations thereof will be omitted. The heating equipment shown in FIG. 1 is new in that the electric circuit between the transformer section 3 and the rectifying and smoothing section 4 includes a second input section 9 consisting of a momentary type power-on switch 9A and an output section 7 that is operated. A first power supply holding section 10 consisting of switching contacts 10A is connected in parallel, and a power supply circuit that supplies DC power from the rectification and smoothing section 4 to the microcomputer 5' which is the control means and the reset section 6 is connected in series. A second power supply holding section 11 is interposed, which includes a connected resistor 11A, a capacitor IIB, and a discharge resistor 11C. The constants of the resistor 11A and capacitor IIB of the second power supply holding section 11 become the initialization release voltage of the reset section 6 (c, the voltage at which the microcomputer 5' starts operating) after a predetermined time after the DC IC source is turned on. It is set as follows. Furthermore, when the switch 9A of the second input section 9 is pressed and the DC IEsj is supplied from the rectifying and smoothing section 4, the microcomputer 5' is supplied with the direct current IEsj via the output section 7 after a predetermined time. The DC power source is held by closing the switching contact 10A of the first power supply holding section 10, and the switching contact 10A of the first power supply holding section 10 is opened after a predetermined time by operation of the input section 8, for example, a predetermined switch 8A. A function is added to cut off the DC power supply.

Next, the operation of the heating device configured as described above will be explained.

Now, when AC power supply l is energized, transformer 3A of transformer section 3
Current flows through the primary side of. At this time, the second input section 9
Both the power-on switch 9A and the opening/closing contact 10A of the first power supply holding part 10 are open, and no current flows and no power is consumed from the secondary side of the transformer 3A. When the user presses the power-on switch 9A in this state, the transformer 3A
The secondary side and the input of the rectifying and smoothing section 6 are energized, and the current flows through the resistor 11A of the second power supply holding section 11 to the capacitor I.
Charging starts in IB. Initially, the t original voltage of the reset section 6 (output voltage of the rectifying and smoothing section 6) is below the predetermined voltage, so the microcomputer 5' is initialized by the reset section 6, and the outputs of all the output sections 7 are It remains off, and the opening/closing contact 2A and IOA remain dead. Here, if the switch 9A is released before the predetermined time set in the second power supply holding section 11 is reached, the outputs of all output sections 7 remain off, and the capacitor I of the second power supply holding section 11
The charge on IB is discharged through resistor 11A and IIC.

If the switch 9A is kept pressed for a predetermined time (key manual determination time), the power supply voltage of the reset section 6 becomes equal to or higher than the predetermined voltage, the initialization by the reset section 6 is canceled, and the microcomputer 5' starts operating. When the microcomputer 5' starts operating, it closes and holds the opening/closing contact 10A via the output section 7, and at the same time emits a key manual reception notification sound with the buzzer 7B and lights up the LED γA. therefore,
After that, the opening/closing contact 10A is connected to the microcomputer 5'.
The power supply is maintained until the current signal is output, and the user can freely set the heating and other settings, and heat can be heated via the output section 7 as necessary.

Next, when a switch in the first input section 8, for example switch 8A, is pressed for a predetermined period of time (key manual determination time), the microcomputer 5' opens the switching contact 10A via the output section 7, and the rectifying and smoothing Although the input power to the section 4 is turned off, the output voltage of the rectifying and smoothing section 4 is held for a while by the second power supply holding section 11 to be higher than the initialization release voltage of the reset section 10, so that the microcomputer 5'
operates, turns off the LED 7A and issues a notification using the buzzer 7B, and then is initialized again by the reset unit 6.

In this way, the power supply switch 9A of the second input section 9
DC power is not applied to the microcomputer 5' until is pressed, and the DC power applied to the microcomputer 5' is cut off by a predetermined input of the first input section 8, so that no direct current power is applied to the microcomputer 5'. It is possible to suppress power consumption as much as possible while waiting for the settings (until the user actually makes the desired settings and operates the heating device). Also,
Since little current flows through the switch 9A of the second input section 9 and the opening/closing contact 10A of the first power supply holding section 10, components with a small allowable current can be used.

In this embodiment, the second input section 9 and the second source holding section 10 are connected in the electric circuit of the transformer section 3 and the rectifying and smoothing section 4, but as shown in FIG. Furthermore, by connecting the AC power supply 1 and the transformer 3 into the electric circuit, it is possible to similarly suppress power consumption as much as possible while the user is waiting for the settings to be made to the heating device.

In the second embodiment shown in FIG.
Components with a large allowable current must be used for the switch 9A and the opening/closing contact 10A of the first power supply holder 10, but the power consumption in the primary coil of the transformer 3 during the setting waiting period is Since no power is consumed, power consumption can be further reduced compared to the first embodiment shown in FIG.

As described above, according to the present invention, when DC power is applied to the control means for the first time due to the operation of the second input section, the control means operates the power supply holding section via the output section. This DC power is held, and the operation of the current holding part is canceled via the output part by a predetermined input of the first input part, and the DC power is cut off. During the period, power consumption by the control means is cut,
Power consumption as a heating device can be minimized.
