Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a room temperature setting method during automatic timer operation in a controller such as a hot air heater.

2. Description of the Related Art A conventional hot-air heater having a 1-hour operation function that sets a start time and automatically starts the operation at the start time, and then stops the operation after 1 hour The set room temperature during the one-hour operation when the operation started was based on the set room temperature before the timer operation.

Problems to be Solved by the Invention Generally, the timer 1 hour operation is used for good morning timer in the early winter season (for example, at a predetermined time before the user gets up, generally 1 hour before the heater is started to heat the room. If the user forgets to wake up, the heating operation is stopped in 1 hour.), And the room temperature is set high so that the room can be sufficiently warmed in the early morning 1 hour operation. However, if the set room temperature is extremely low, the equipment will stop operating before the room is completely warmed up. In particular, when the room temperature rises sufficiently during use on the previous night, the set room temperature is often set lower and used, which is a factor causing the above-mentioned inconvenience.

If the set temperature is too high, the continuous maximum output will be obtained during the 1-hour operation of the timer, which is not preferable in terms of energy saving.

In view of the above problems, the present invention provides a control device such as a warm air heater capable of selecting means for fixing the indoor temperature setting to an appropriate temperature when the timer is operated for a predetermined time.

Means for Solving the Problems In order to solve the above problems, the control device such as the hot air heater according to the present invention presets the indoor temperature setting during the predetermined time operation by the timer, the timer operation set temperature storage means. And a timer operation set temperature mode switching means for enabling selection of the timer operation set temperature storage means and the set temperature storage means before selection of operation for a predetermined time by the timer.

Operation According to the present invention, the indoor temperature setting during the timer operation can be selected by switching between the indoor temperature setting in the normal operation mode and the indoor temperature setting during the timer operation by the above-described configuration.
That is, if the timer operation setting temperature mode is not switched, the temperature control during the normal operation is executed, and the timer operation setting temperature mode is switched, so that the room temperature can be set to an appropriate room temperature as desired.

Embodiment One embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 is an indoor temperature detecting means, and an indoor temperature detection signal is obtained by converting an analog signal from a temperature sensor such as a thermistor 2 and a signal from a D / A converter 3 into a binary code by a comparator 4. Is read by the microcomputer 5.

The microcomputer 5 shown here is a so-called one-chip microcomputer having a CPU, a ROM, a RAM, and an input / output unit. Reference numeral 6 is a KEY signal generator, which is a KEY switch 7a of the room temperature setting means 7 and a "timer" / "normal" operation mode switching means 8

When the SCAN output (for example, 0) of the microcomputer 5 becomes the HI output when the KEY switch 7a of the room temperature setting means is pressed, the resistance R1 and the KEY switch 7 are changed from V _S.
a, current flows to the inverter IC1 through the diode D1,
As a result, the LO signal is input to the KEY input (for example, 0) of the microcomputer 5 and the microcomputer 5 becomes KE.
It is judged that the Y switch has been pressed once, and the room temperature setting is set to 1ST.

When N output (eg, 1) becomes HI output, a “timer” / “normal” operation mode switching signal is input to the KEY input (eg, 1) and the microcomputer switches from “timer” to “normal”.
Or switch the operation mode from "normal" to "timer". Similarly, pressing the KEY switch 9a once advances the start time setting by 1 STEP (for example, 1 minute). Next, if there is the short-circuit wire 10a, when the SCAN output (for example, 3) becomes the HI output, the LO signal is input to the KEY input (for example, 3) and the microcomputer 5 judges that it is the timer operation set temperature mode switching signal, As the room temperature setting during the timer 1 hour operation, the timer 1 hour operation is performed at the timer operation set temperature that is already set in the ROM of the microcomputer. 11 is an LED display circuit, and a large number of L
The ED12 displays the set temperature, room temperature, start time, etc. Reference numeral 13 is an electromagnetic valve drive circuit, 14 is a proportional valve drive circuit, 15 is an igniter drive circuit, and 16 is a fan motor drive circuit, which are driven by sequence control signals from the microcomputer 5, respectively.

Next, FIG. 2 shows a block diagram. Inside the microcomputer 5, a set temperature storage means 5a for storing signals from the indoor temperature setting means 7, a timer operation set temperature storage means 5b for storing preset indoor temperature settings, and a "timer"
/ "Normal" operation mode switching means 8 for determining the signal from the "timer" / "normal" operation mode determining means 5c, start time setting means 9 for setting the start time storing means 5d for storing the time set by the signal Temperature deviation calculation means 5e for calculating the temperature deviation between the temperature and the room temperature, heating output control means 5f for outputting an output signal according to the temperature deviation, sequence control means 5g for controlling the sequence according to the set operation mode of the equipment, timer operation Each means of timer operation 1 hour counting means 5h which counts hourly operation time 1 hour and outputs a signal is provided.

Next, the operation of the above embodiment will be described with reference to the flowchart of FIG.

Indoor temperature detection means 1 when the appliance is operating "normally"
The temperature deviation between the indoor temperature detection signal by the indoor temperature detection means and the signal set by the indoor temperature setting means 7 and stored in the set temperature storage means 5a is obtained by the temperature deviation calculation means 5e, and the heating output signal according to the temperature deviation is controlled by the heating output control. It is output from the means 5f to the proportional valve drive circuit 14 and the fan motor drive circuit 16. "Timer"
/ When the switching signal is input to the microcomputer 5 by the "normal" operation mode switching means 8, the "timer" / "normal" operation mode determination means 5c determines that the timer operation mode is selected and the sequence control means 5g stops the operation of the instrument. To do.
Then, when the starting time is set by the starting time setting means 9, the starting time is stored in the starting time storage means 5d. When the start time comes, the control signal from the sequence control means 5g is output to the solenoid valve drive circuit 13, the proportional valve drive circuit 14, the igniter drive circuit 15, and the fan motor drive circuit 16 to start the operation of the appliance. At this time, if the short-circuit line 10 of the timer operation set temperature mode switching means 10 is present, the operation is performed at the set temperature stored in the timer operation set temperature storage means 5b, and if the short-circuit line 10a is not present, the temperature stored in the set temperature storage means 5a is set.
