Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to an air conditioner, for example, a heater and a cooler, and particularly, an operation reservation that is automatically activated after a period of one day or two days has passed is easy and reliable. The present invention relates to a control device for an air conditioner.

(Prior Art) In the case of an air conditioner currently used, for example, a heater,
Especially for business use, many of them are designed to automatically restart operation the next morning when the operation is stopped at the end of the day's work, and a reservation called a good morning timer by a microcomputer It is common to have a device that can easily adjust the reserved time to be automatically activated by a timer.

(Problems to be solved by the invention) As described above, the reason why the good morning timer is required is that the negative side heat storage load exists in buildings, factories, etc. when heating is stopped for a long time. This is because the heat storage load on the negative side becomes large, and the effect of heating does not immediately increase when operation starts, so heating operation must be started earlier than when attending work or starting work.

In particular, at the end of the weekend and after consecutive holidays, it goes without saying that this tendency is large, and in order to require a long reservation time, the good morning timer is indispensable and such a preheating operation is necessary. It is a known fact as described in "New Edition Air Conditioning Handbook (January 20, 1972, 10th edition, Maruzen Co., Ltd., Chapter 3, Air Conditioning Load, Appendix, Heat Storage Load, page 79)".

By the way, since the conventional timer referred to as the good morning timer described above is designed to be digitally displayed on the display unit for both time display and room temperature display, it may be used as a clock, so it may be used for 24 hours or 12 hours. Even though it is possible to reserve time for automatic driving at a predetermined time the next morning after stopping the operation at night after the work ends, it is a structure that makes the time cycle, so a full day off, early morning on the day after the consecutive holidays It is not possible to make a time reservation at the time, and as a result, it is inconvenient for the maintenance staff to take measures such as going to work early in the morning when such special operation is required.

Thus, the present invention has been made in view of the disadvantages of the conventional ones, and in an air conditioner having a reservation timer typified by a digital display time adjustment method by such a microcomputer, Reserving time for automatic driving by simple operation, not by day, but by adding 1 day, 2
By making it possible to set the time for day addition, it is possible to achieve rational and fully unmanned automatic start-up control, and to promote the spread of devices with high operating economy.

(Combined) switch (2), timer mode switch (3) and operation stop switch (5) respectively provided therebelow, and display changeover switch (6) provided on the left side of time setting switch (2) are close to each other. Further, a clock indicator light (11), a time adjusting lamp (12) and a timer adjusting lamp (13) are provided side by side in a line.

On the other hand, in the control panel (1), there is provided a control system consisting of the element circuits (14) to (19) shown in block form in FIG. 1, and these element circuits (14) to (19) are It is formed by a control device equipped with a processing unit (CPU), a microprocessor (MPU), and each memory (RAM) (ROM),
The respective switches, the respective indicator lights, etc., which have been described above, are in contact with each other.

When the reservation timer (14) receives the time setting signal from the time setting signal generating means (18), it is possible to set a reservation time for issuing an air conditioning operation signal for outputting an operation command to the burner and fan of the heater, In addition, a lighting command can be output to the reserved time display lamp (8) at the same time as this setting, and it also has a function as a clock by performing timekeeping with a cycle of 24 hours.

The 1-day addition timer (15) is a timer that measures the time of 24 hours from the time when the operation command is sent, and outputs a lighting signal to the 1-day addition indicator lamp (9) while the operation command is sent. At the same time, even if the reservation time is set in the reservation timer (14), a prohibition command is output so that the air conditioning operation signal is not output, and at the same time the reservation time indicator lamp (8) is output.
Also, the lighting command for is operated to prohibit the output.

On the other hand, the 2-day addition timer (16) has a function equivalent to that of the 1-day addition timer (15), and measures 48 hours from the time when the operation command is sent, and 2 hours during that time.
A lighting signal is output to the day addition indicator light (10), a prohibition command is output to the reservation timer (14) so that the air conditioning operation signal is not output, and at the same time, a lighting command is also output to the reservation time indicator light (8). Operates to ban.

Next, the reservation canceling means (17) outputs a cancel signal that is appropriately output by a timer or the like when the heater starts and enters stable operation, and the cancel signal output from a timer mode switch (3) described later. It operates so as to receive one of the fourth command signals belonging to the same type, and outputs a signal for canceling the already set reservation time to the reservation timer (14).

Further, the time setting signal generating means (18) has an input terminal connected to the signal output terminal of the time setting switch (1) and an output terminal connected to each input terminal of the digital display section (4) and the reservation timer (14). Receiving a setting signal from the switch (2), outputting a signal indicating the reserved time to the digital display section (4), and generating the setting signal so that the output terminal does not output the signal only for a predetermined short time. It is formed so that it can be retained internally.

The timer mode switch (3) generates a pulse signal each time the switch is lightly pressed and sends the pulse signal to the mode switching means (19). The mode switching means (19) first receives the first command signal each time the pulse signal is received, and then the second command signal.
The fourth command signal is formed so as to be repeatedly transmitted in the order described, and the first command signal is sent to the time setting signal generating means (18) so that the time setting signal held by the means (18) is retained. It functions as a relay signal to be input to the reservation timer (14).

On the other hand, the second command signal is an operation signal to be transmitted to the timer (15) in order to time the day addition timer (15), and in the present example, at the same time, the reserved time indicator lamp (8).
A signal for turning off the light is output.

Next, the third command signal is an operation signal transmitted to the two-day addition timer (16) in order to operate the two-day addition timer (16), and in this example, the one-day addition timer (15) is simultaneously sent.
It also outputs a signal to turn off.

Next, the fourth command signal is a command signal for setting the reservation time, timing operation related to the setting, and canceling all the lighting display, that is, activating the reservation canceling means (17), and A command signal for canceling the third command signal is output to the 1-day addition timer (15), the 2-day addition timer (16), the reservation cancellation means (17) and the time setting signal generation means (18), respectively. ing.

In addition, in FIG. 1 and FIG. 3, the display changeover switch (6)
Displays the digital display (4) with a clock every time it is lightly pressed, and displays the first display for turning on the clock indicator lamp (11) and the digital display (4) with flicker for time adjustment, and also performs time adjustment. Second display for turning on the lamp (12), third display for displaying time on the digital display (4) for timer adjustment and turning on the timer adjusting lamp (13), and extinguishing each lamp (11) to (13) The digital display (4) is switched to the temperature display and the fourth display is repeated in order. Therefore, it is set every time the touch switch (2A) is pressed after setting the state of the fourth display. The temperature can be changed by 1 ° C on the rising side, and every time the touch switch (2B) is pressed, the temperature is lowered by 1 ° C.
In this case, the left side of the digital display unit (4) displays the set temperature and the right side displays the current temperature inside the room.

On the other hand, by setting the state of the 3rd display and pressing the touch switch (2A), the time unit of the time can be advanced by 1 hour and the time unit of the reservation timer (14) can be set. By pressing the touch switch (2B), the minute unit of time can be increased by 1 minute and the same minute unit can be set.

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

When it becomes late at night when the heating operation of the day ends, the operation is stopped by pressing the operation stop switch (5).

The circuit configuration is such that the reserved time cannot be set unless the operation switch (5) is used to stop the operation, thereby avoiding an erroneous stop operation.

Then, the display changeover switch (6) is operated in step (S ₁ ) to turn on the timer adjusting lamp (13), and at the same time, the digital display section (4) is changed over to the timer adjusting lamp (4). "12" and "00" are displayed as non-setting status.

After confirming this state, operate both switches (2A) and (2B) of the time setting switch (2), for example, "7""30"
(Note: indicates blank), that is, set at 7:30 am.

Thus, "7" and "30" are displayed on the digital display section (4), while the time setting signal is output to the time setting signal generating means (18).

Next, in step (S ₂ ), the timer mode switch (3) is operated, but the first operation from the current state corresponds to the transmission of the first command signal, and in that state, the reserved time indicator lamp (8) The reservation time is set by turning on the light and inputting the time setting signal to the reservation timer (14). By leaving it as it is, step (S ₃ ) is reached and the time measurement of the reservation timer (14) is started. Then, at 7:30 the next morning, the heating operation is automatically performed and the reservation timer (14) is automatically reset (step (S ₄ )).

On the other hand, when the timer mode switch (3) is further operated at the second or third time in step (S ₂ ),
In the second time, the process proceeds to step (S ₅ ), the 1-day addition timer (15) is activated, the 1-day addition indicator light (9) is turned on instead, and the timer (15) starts counting ( Step (S ₆ )
And, 24 hours reservation timer (14) timed is further applied for by moving to step (S ₃₎ with the passage, the Reservation Timer morning two days later, the heating operation in 7:30 is automatically performed ( automatic reset of 14) is made (step (S _4)).

On the other hand, if the operation is performed up to the third operation, the steps (S ₇ ) and (S ₈ ) are sequentially performed, the 2-day addition timer (16) operates in place of the 1-day addition timer (15), and The two-day addition indicator light (10) lights up, and the heating operation is started at 7:30 am on the next day after two days by the timer (16) and the reservation timer (14). Reservation timer (14)
Automatic reset of is made (step (S _4)).

If the timer mode switch (3) is used to perform the fourth operation, which is one addition to the above three operations, the reservation timer (1
The time setting in 4) is canceled and the status is returned to the state where the initial reservation time has not been set.

In this way, one switch can easily set the automatic operation by the timer the next day, two days later, and three days later, and the time setting can be canceled without fail by the sequential repetitive operation. There is no inconvenience such as incorrect setting of the reserved time.

In the example explained above, only the reserved time indicator light (8) lights when the reserved time is set for the next day, and only the 1-day addition indicator light (9) is set for the next two days every other day. Two
Only the two-day addition indicator light (10) is configured to light up when the next day after the day after the date is set, but the function of each timer (14), (15), (16) If the reservation time is set by making a slight modification, the reservation time indicator light (8) lights up, and the 1-day addition indicator light (9) or the 2-day addition indicator light (10) is added to this. Can be turned on at the same time. For example, if the next day after the next day is set as the target day, the first 24 hours is the 2 day addition indicator light (10) and the next 24 hours is 1 day. Addition indicator light (9)
It is of course possible to adopt a switching lighting system in which the lights are switched and lighted in order, and then the reservation indicator light (8) is also lighted, and such a modification is also included in the scope of the present invention. .

(Effect of the Invention) As described in detail above, the present invention can be used as a watch.
The 24-hour reservation timer (14) is added to the 1-day addition timer (1
5) You can easily make time reservations two or three days after adding one day or two days by combining the two-day addition timer (16), so you can reliably and easily make automatic driving reservations after holidays and consecutive holidays. Can be set to.

Furthermore, every time the timer mode switch (3) is pressed, it is possible to set the automatic driving and cancellation of the automatic driving reservations by the timer on the next day, 2 days, 3 days later in sequence, and it is possible to control the type of these reservations. Since the three display lights (8), (9), (10) on the panel (1) display different states, reservations can be easily set by repeated operations in sequence, and In addition, the reservation status at that time is indicated by the indicator lights (8), (9),
The display of (10) makes it easy to confirm, and as a result, the operational effect of reliably eliminating an error in the reservation operation of the timer mode switch (3) is achieved.

In addition, in the case of the operation of changing the time reservation or after the operation started at the reserved time, the reservation canceling means (1
According to 7), the setting of the reserved time is always cancelled, so that it is possible to provide a highly reliable device without any inconvenience such as unnecessary repeated automatic driving, or failure to reach driving when necessary.
