Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a clothes dryer whose operation is automatically controlled by an electronic control device such as a microcomputer.

[Conventional technology]

First, to explain the overall structure of the clothes dryer, Fig. 4,
As shown in Figure 5, there is a door (1
A motor (27) and a rotating drum (16) which is a drying chamber rotated by the motor (27) are disposed in a body (28) having a main body (28). (16) A round bell (25) is hung between the rotating shaft of a double-winged fan (24) installed behind the rear exhaust hole via a filter (17).

In addition, an intake port (19) is provided on the back of the body (28) to take in outside air for cooling, and a drain port (29) is provided on the bottom surface for discharging moisture removed from the material to be dried.
A heater (21) is arranged in front of the rotating drum (16), and a temperature sensor (
22) to the filter (17) behind the rotating drum (16)
A temperature sensor (23
) was attached near the intake port (19).

Below the door (18) on the front side of the body (28), there is an operation panel (20) having a control switch (1) for setting the drying operation time, etc., and a progress display section (11) for displaying the progress status of the drying operation. will be established. A control device (3) using a microcomputer or the like is built into this operation panel (20), and the control device (3) is connected to a control switch (1) as shown in the control block diagram of FIG. a control setting section (4) into which a setting signal of the temperature sensor (22) is introduced;
(23), a calculation section (5) into which the output signal from the temperature measurement circuit (2) is sampled every minute, for example, and a time counting section (5) that measures the operating time.
6), based on the output signals from the storage section (7) that stores the temperature etc. introduced into the calculation section (5), the control setting section (4), the calculation section (5), and the time limit counting section (6). It is composed of a motor/heater control section (8) that controls power supply to the heater (21) and motor (27). The output signal from the control setting section (4) was also introduced into the progress display section (11). In the figure, (12) indicates a power supply section.

In this way, to perform drying operation, open the door (18), put the clothes to be dried into the rotating drum (16), and press the control switch (1) on the operation panel (20). Once the drying time and degree of drying are set, the output signal from the control switch (1) enters the motor/heater control section (8) via the control setting section (4), and the control signal from here is sent to the motor (27). ), the motor (27) is energized and rotates. As a result, at the same time that the rotating drum (16) starts rotating, the rotation of the motor (27) is transmitted to the double-winged fan (24) via the round belt (25), causing it to rotate. In addition, the motor/heater control section (8
) is also applied to the heater (21), which is energized.

Then, due to the rotation of the double-winged fan (24), the intake port (19)
) The outside air taken into the body (28) is heated by the heater (21) and turned into dry hot air, which is sent into the rotating drum (16) and hits the object to be dried. As a result, the material to be dried is heated and the hot air becomes moist warm air containing moisture evaporated from the material to be dried, and the rotary drum (1
6) through the filter (17) to the double wing fan (24) side. The humid warm air that hits the double-wing fan (24) is cooled by contacting the cold outside air taken in from the intake port (19), which removes moisture and sends it back to the heater (21) where it is removed. The collected moisture is discharged to the outside of the body (28) from the drain port (29), and this circulation is repeated to perform drying operation.

On the other hand, the time limit counting section (6) counts the operating time, and the progress display section (11) displays the operating state moment by moment based on the output signal from the control setting section (4).

Further, the temperature sensor (22) measures the exhaust temperature of the air discharged from the rotating drum (16), and the temperature sensor (23)
Now, the indoor temperature of the outside air taken in from the room outside the fuselage (28) is measured. The exhaust gas temperature and the room temperature are sampled by the temperature measuring circuit (2) every minute, for example, and the arithmetic unit (5)
) or the storage unit (7) compares and calculates both temperatures, and when the calculation result, that is, the difference between both temperatures reaches a predetermined value at a predetermined time,
It is determined that the drying of the material to be dried is completed, and the motor is turned off.
The heater control unit (8) stops energizing the heater (21) and motor (27) to end the drying operation.

By the way, this drying operation takes, for example, 220 minutes at maximum, and the amount of electricity required for this is also considerable.

However, none of the conventional clothes dryers was equipped with a means for calculating and displaying the electric power charge for this amount of electricity.

[Problem that the invention seeks to solve]

For this reason, it is difficult for users to know how much electricity is required when operating a clothes dryer. It was difficult to manage electricity usage because it was not easy to know the electricity consumption.

An object of the present invention is to solve the above-mentioned disadvantages of the conventional example, and to provide an easy-to-use clothes dryer that can easily display the electricity consumption due to the operation of the clothes dryer and know it as needed, which is useful for managing electricity usage. The aim is to provide the opportunity.

[Means for solving problems]

In order to achieve the above object, the present invention provides a clothes dryer that dries items to be dried stored in a drying chamber using hot air from an electric heater controlled by a control device. The gist of the present invention is to include means for calculating the power usage fee based on the stored operating time, and means for displaying the power usage fee.

(Operation) According to the present invention, based on the cumulative operating time stored in the storage means, the calculation means uses data stored in advance such as power consumption per unit time and electricity rate per IKW of electricity. The electricity charge will be calculated and displayed, so
You can know the power usage fee at any time if necessary 6 [Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a control block diagram showing an embodiment of the clothes dryer of the present invention. In the figure, the same components as in the conventional control block diagram shown in FIG. 6 are denoted by the same reference numerals. A detailed explanation will be omitted. Further, since the overall structure of the clothes dryer of the present invention is the same as that already explained with reference to FIGS. 4 and 5, detailed explanation will be omitted here.

In addition to the control mechanism numbers shown in FIG. 6, the present invention uses an input key (14) for inputting the electricity rate per IKW on the operation panel (20) and a numeric display for displaying the electricity rate used. A display device (13) is provided, and one of the control switches (1) is a display device for electricity usage charges. ! (13) A switch is provided to instruct the display.

Further, the motor power consumption and heater power consumption per unit time are stored in advance in the ROM of the storage unit (7) in the control device (3).

Further, a backup circuit (15) is connected to the control device (3) in addition to the power supply section (9).

Next, to explain the usage and operation, first, the door (1
8), put the clothes to be dried into the rotating drum (16), enter the drying time and degree of drying using the control switch (1) on the operation panel (20), and press the input key ( 14
) to input a numerical value indicating the electricity rate per IKW of electricity and store it in the storage unit (7). This is a big cam for electricity bills, you don't need to do it every time you drive, just set it once.
There is no need to re-enter until changes are made. Note that even if there is a power outage, this set value will not be lost due to the power supply from the bank amplifier circuit (15).

When a control signal from the motor/heater control section (8) is input to the heater (21) and motor (27), these are turned on and the drying operation starts in the same manner as in the conventional method.

To accumulate the drying operation time, as shown in the flowchart in Fig. 2, when the ON signal I] is output from the motor/heater control section (8) to the heater (21), the heater (21 ) turns on and stenopui)
, and if the 1 second flag for calculating 1 second is set (
Step port), add 1 second to the heater energization time memory (Step port). Also, when the on signal H is output from the motor/heater control unit (8) to the motor (27), the motor (27) turns on (Step 2), and the flag remains on for another 1 second. Ba(
Step E), add 1 second to the motor energization time memory (Step E). In this way, the energization time between the heater (21) and the motor (27) is limited to the time count section (6).
When it is determined that the temperature value calculated by the calculation unit (5) based on the data measured by the temperature measuring circuit (2) and outputted from the temperature measuring circuit (2) reaches a predetermined value and the drying operation end step has been entered,
From the motor/heater control section (8) to the heater (21)
Then, the output signal to the motor (27) becomes L, which is an off signal, and the power supply to the heater (21) and the motor (27) is stopped, and the operation ends. The energization time A'' to the heater (21) and the energization time B'' to the motor (27) are each stored in the storage section (7).

Next, in order to know the electricity consumption after the end of operation, as shown in the flowchart in Figure 3, when the power to the heater (21) and motor (27) is stopped and the end of operation is detected (step ), first, the electricity rate C per power IKW stored in advance in the storage unit (7) is read out to the calculation unit (5) and temporarily stored (step 1), and the R of the storage unit (7) is
The motor power consumption per unit time and the heater power consumption E, which are stored in advance in the OM, are read out to the calculation section (5) and temporarily stored therein (Sterapuri, Nu).

Next, read out the heater energization time A' (stellar pull), integrate this heater energization time A', the heater power consumption E, and the electricity charge C to obtain the heater power consumption charge A, and store this ( Also, read out the motor energization time B (Stellapuri), integrate this motor energization time B, the motor power consumption, and the electricity charge C to obtain the motor power consumption charge B, and store this. (step force). Then, the heater power consumption amount and the motor power consumption amount B are added to obtain the total power consumption amount M required for the drying operation, and this is stored in the RAM of the storage unit (7).

To know this total power consumption charge M, use the control switch (1
) to instruct the display, the control setting section (
4) reads out the power consumption charge M from the storage unit (7) and displays it on the display device! Displayed in (13).

In addition, if a power outage occurs and the power supply from the power supply unit (9) to the control device (3) is cut off, the power outage will be detected by the boat of the control device (3), and the backup circuit (15) will supply power to the control device (3). (3) to maintain the RAM by supplying power to it. Therefore, even if a power outage occurs, data on total power consumption charges will not be lost.

In the above embodiment, the power consumption charge is calculated for each operation, but even if the power supply from the power supply unit (9) is cut off, the RAM is retained by the back amplifier circuit (15). From this, it is also possible to calculate the total power consumption charge over a long period of time, such as one month or one year.

〔Effect of the invention〕

As described above, the clothes dryer of the present invention can easily calculate the power consumption required for operation, and can easily display and know this if necessary, so it is useful for managing power consumption. It is easy to use.
