Description

Description: TECHNICAL FIELD The present invention relates to a timer device used for controlling electric blankets, electric carpets, and the like.

(Prior Art) Conventional timer devices can be roughly classified into two types, a time setting type and a time setting type. The time setting type outputs a signal when the set time is reached, and controls the device by the signal. Further, the time setting type is for outputting a signal after measuring a set time and controlling the device by the signal.

(Problems to be solved by the invention) However, the conventional time setting type has the convenience that the device can be controlled at a desired time only by setting the desired time, while the time display for displaying the time is provided. Since there is a need to provide a device, there is a problem in design that the shape of the operation unit becomes large, and there is a problem that a manufacturing cost becomes high because a time display device is newly provided.

In addition, the time setting type has a problem that it is difficult to set the time. For example, if you try to control the device at the same time every day, you have to set the number of hours after the desired time back from the current time, which is a hassle, and it is very difficult to use. was there.

The present invention provides an inexpensive and easy-to-use timer device having a function equivalent to that of a time setting type, without the need for enlarging the shape of the operating portion.

(Means for Solving Problems) In order to solve the above problems, the present invention provides a timed timer that time-ups after a set time elapses and outputs a time-up signal at each time-up, and the timed timer. And a time limit setting section for setting the time, and resetting the time of 24 hours to the time timer when the time timer is up.
A 24-hour timer unit including a time limit setting unit, a timer output control unit that prohibits or permits transmission of the output of a time-up signal of the 24-hour timer unit, and a prohibition or permission of transmission of the output to the timer output control unit. It comprises a timer output control setting unit for setting and an output unit for starting operation by a signal output from the timer output control unit.

(Operation) According to the present invention, with the above-described configuration, the 24-hour timer section periodically outputs the time-up signal every 24 hours after the internal time-out timer has timed out. The time calculated from the current time is set to 1 in the timer.
If you set it once, you can control the device connected to this device at that time every day, and even though it is a timed timer, it will show the same function as the time setting timer after setting the time once, and the time display device is also unnecessary Therefore, the operation unit can be downsized.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

FIG. 1 is a plan view of an electric carpet equipped with a timer device according to an embodiment of the present invention, in which 1 is a carpet body,
Reference numeral 2 is a heater unit, and 3 is an operation unit.

FIG. 2 is an enlarged plan view showing the configuration of the operation unit 3 of FIG. 1, and 5 is a time period set in a timed timer described later.
Time setting UP switch that advances by time, 6 is a time setting DOWN switch that advances the time set in the time limit timer by 1 hour, and 7 is an LCD (liquid crystal display) that displays the set time
A device, 8 is a timer selection switch for selecting whether to permit or prohibit the timer operation, 9 is a mode for setting the timer time (time setting mode), a mode for normally operating (normal mode) and a mode for cutting off the power (off mode) ) Is a mode changeover switch for changing over three kinds of modes.

FIG. 3 is a block diagram showing the configuration of the main part of the timer device of the present embodiment, in which 10 is a time setting section, 11 is a time timer,
12 is a 24 time limit setting unit, 13 is a timer output control setting unit, 14 is a timer output control unit, and 15 is an output unit. The control of the operation of each of these parts is performed by the microcomputer contained in the operation part shown in FIG. 2, and the storage location of the set time is the RA
Assigned in M. The time limit setting unit 10 operates by operating the time setting UP and DOWN switches 5 and 6 shown in FIG. 2, and the timer output control setting unit 13 operates by operating the timer selection switch 8 also shown in FIG. .

In the above configuration, first, when the user uses the carpet for the first time, it is connected to a commercial power source through a conset or the like. In this state, the mode changeover switch 9 provided in the operating portion 3 of the carpet is in the "off mode", and the microcomputer of the operating portion 3 is energized, but the carpet heater is not energized.

Here, when the user wants to use the carpet, the user switches the mode selector switch 9 to the "normal mode" so that the carpet heater is energized for heating. When stopping the use of the carpet, the user switches the mode selector switch 9 to the "off mode". Then, although the microcomputer of the operation unit 3 is energized, the carpet heater is not energized and heating is not performed.

Next, control of energization of the carpet heater by the timer device will be described. In this embodiment, the timer operation is an "automatic timer" that energizes the electric carpet at the same time every day.
I will explain as.

First, the timer is set. When setting the time of the timer, the user switches the mode changeover switch 9 to the "time setting mode", and then while watching the display unit 7, the time setting UP / DOWN switches 5, 6 of the time setting unit 10 are set. Press to set how many hours after the current time of the setting operation you want to use the carpet. In this example, if the user wants to use it at 6 am the next day, and if it is 8 hours after the current time, the time setting UP / DOWN switches 5 and 6 are operated so that "8" is displayed on the display unit 7. To do.

After that, when the user switches the mode changeover switch 9 to the "normal mode", the carpet heater is energized, but when the timer selection switch 8 is pressed, the energization is stopped, whereby the energization control state by the timer device is set. Then, the timed timer 11 starts to operate, and the microcomputer operates to stop the power supply to the carpet heater based on the signal from the timer selection switch 8.

If the user does not operate the operation unit 3,
At 6 am the next day, the time limit timer 11 expires, the timer selection switch 8 is turned off, and the timer output control unit 14
Outputs a time-up signal to the output unit 15 so that the microcomputer operates so as to energize the carpet heater, and heating is performed. That is, at this time, the timer selection switch 8 is turned off, and the energization control state by the timer device is returned to the energization control state by the "normal mode", which is the same as when the mode changeover switch 9 enters the "energization mode". Then, in response to the time-up signal, the microcomputer operates the 24-time period setting unit 12 to start counting time for 24 hours from that point.

If the user wants to energize the carpet heater at the same time on the next morning after 6:00 am when the time is up, the user may press the timer selection switch 8, which causes the microcomputer to once again enter the energization control state by the timer device. To do. Therefore, when the 24 time limit setting section 12 times up at 6 am the next day, the 24 time limit setting section 12 is restarted in response to the signal, and the timer output control section 14 outputs a time up signal to the output section 15 to send a micro time signal. The computer operates so as to energize the carpet heater, and heating is performed.

If the user does not need to energize the carpet heater at the same time the next morning, the user may not press the timer selection switch 8 (selection by the microcomputer).
In this state, the user presses the timer selection switch 8 at any time to enter the energization control state by the timer device as described above. Therefore, reset the timer or use the commercial power supply. As long as you do not turn off, the setting state in the microcomputer will not change, so the operating 24-time setting unit 12 will time up at 6 am the next day,
After that, the same operation as described above is performed.

When the heating state is changed to the state where the carpet does not have to be used, the user is asked to change the mode switch 9
To switch to "off mode". In this state, the microcomputer of the operation unit 3 is energized, but the carpet heater is not energized and heating is not performed. And when in this non-heating state,
If the user switches the mode changeover switch 9 to the "normal mode" at an arbitrary time, depending on whether or not the timer selection switch 8 is pressed, it is possible to select whether or not the above-described energization control state by the timer device is set. It becomes possible.

Next, the operation control by the microcomputer will be described with reference to the operation control flowchart of FIG.

The timer selection switch 8 is used for the tact SW detection processing of S24 (step 24) and S40 (step 40) in the flowchart.
Is detected, and the timer permission flag is inverted every time it is input (ON). First, in S16, clear all ports and RAM related to timer operation, determine the mode in S17, and if "normal mode", detect the input of the timer selection switch 8 in S24, and operate the timer in S25. Determine whether is allowed. If the timer operation is not permitted, energization is performed in S26 and the loop is returned to S17. If it is permitted, energization is stopped in S27 and the set time data is set in the timer, and the timer is started in S28.

After that, the mode is determined in S30 until the time limit timer 11 times out in S29, and the "normal mode" is set.
If so, the input from the timer selection switch 8 is detected in S40, and it is determined in S31 whether or not the timer operation permission is continued. If it is continued, the energization is cut off in S39 and the time limit timer 11 is timed out in S29. The control operation of determining whether or not it is repeated is repeated. If it is determined in S29 that the time is up, the time-up signal is output in S36 to energize, and the 24-hour timer is set in the time limit timer 11 in S35.
Start the 4-hour clock. If the mode is determined in S17 and it is not the "normal mode", it is determined in S18 whether it is the "off mode", and if it is the "off mode", the power supply is cut off in S19. If it is determined in S18 that it is not in the "off mode", the power supply is cut off in S20 and it is determined in S21 whether it is the "time setting mode".
The time data input in S22 is processed. If it is determined in S21 that it is not the "time setting mode", S23 determines that it is the "abnormal mode", error processing is performed, and the control operation loop returns to the first step S16.

If the mode is determined in S30 and it is determined that the mode has been switched from the "normal mode", the timer operation is prohibited in S37, and if the mode is switched to "OFF" in S33, the power is cut off in S34 and the timed timer 11 is determined in S32. Determines if the time is up, and if it is up, the time timer 11 is set to 24 in S35.
Set the time timer. If the time is not up, the process returns to S30 and the control operation is repeated. If it is determined in S33 that it is not in the "off mode", the process returns to S20 and the control operation is performed.

If it is determined in S31 that the timer operation has not been permitted, the power is turned on in S38, and thereafter, the control operation after S32 is performed after the power is turned off in S34. When the 24-hour timer is set in the time limit timer 11 in S35 and the 24-hour re-timer is started, the timer operation is temporarily prohibited (the timer selection switch 8 is turned off) in S41. After that, the time limit timer 11 is set until a new time limit is set or the power supply is stopped.
A timed timer can be created by periodically repeating the 24-hour clock.
Not only is 11 used as a timed timer, but it is possible to control the power supply to the carpet at the same time every day without setting the function equivalent to the time setting timer by setting only once, that is, every day. .

It is obvious that the timer device of this embodiment can be used for any other device used at a certain time every day.

(Effect of the invention) According to the present invention, since the timer unit outputs the time-up signal in a 24-hour cycle, once the timer is set to the desired time, the device connected to the device at that time is operated every day. Although it is a timed timer, it can perform the same function as the time setting timer after setting the time once even though it is a timed timer, and the timer operation can be easily enabled or disabled by turning the timer selection switch ON or OFF. In addition, since the time display device is unnecessary, the operation unit can be downsized and the manufacturing cost can be reduced.
