Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a timer operation device for an air conditioner represented by a fan convector having a timer operation function, an oil hot air heater, and the like.
[0002]
[Prior art]
Conventionally , in this type of air conditioner, in addition to the normal operation mechanism, “on” timer mode setting means for reserving the start of operation of the device, “off” timer mode setting means for reserving the stop of the operation of the device, A timer operation device having a time setting means for setting a start time and an operation stop time is provided, and these operation modes are appropriately set so that the operation period of the device can be freely set.
[0003]
In the above-described conventional air conditioner, an “on” timer operation that starts the operation of the device at the time reserved by the time setting means, an “off” timer operation that stops the operation of the device at the reserved time, and Is capable of executing a combined timer operation that starts the operation of the device at a reserved time using both of them and stops the operation at the reserved time.
[0004]
In the case of combination timer operation, if the operation start time and the operation stop time are set at the same time, the control system cannot determine whether the operation has started or stopped and the inconvenience that the operation becomes impossible. In such a case, there is a control means that disables the timer operation and displays an error on the operation unit to notify the user that there is an error in the time setting.
[0005]
[Problems to be solved by the invention]
However, in the above-described conventional device, if the same time is set as described above, it is considered an error in any operation mode, so that it is a case of “ON” timer operation or “OFF” timer operation. However, the same time cannot be set. In this case, the operation start time and the operation stop time are set at the same time in advance, so that it is not possible to properly use the “on” timer operation and the “off” timer operation, which is extremely convenient for the user. It was bad.
[0006]
The present invention is intended to eliminate the above disadvantages. When setting the timer operation time, even if the operation start time and the operation stop time are set at the same time, the “ON” timer mode or “OFF” It is an object of the present invention to provide an easy-to-use air conditioner timer operation device that improves the operability of the device by causing a predetermined timer operation to be executed without causing an error in the timer mode.
[0007]

That is, according to the present invention, “ON” timer mode setting means for reserving the operation start of the device, “OFF” timer mode setting means for reserving the operation stop of the device, and the operation start time and operation stop time are set. and a time setting unit in the operation unit, when the "oN" timer mode is set by the "oN" timer mode setting means, to start operation in the set operation start time by the time setting means "oN" timer When the “OFF” timer mode is set by the “OFF” timer mode setting means, the “OFF” timer operation that stops the operation at the operation stop time set by the time setting means, and the “ON” and “ON” oFF "when the" ON "timer mode and" oFF "timer mode is set together by both the timer mode setting means, the set operation start by the time setting means In the timer operation system of an air conditioner having an operation control means for performing a combined timer operation, respectively for stopping the operation to set the operation stop time by the time setting means starts the operation in time, the operation control means In the case of the “on” timer operation and the “off” timer operation, the predetermined timer operation is executed even when the operation start time and the operation stop time are set at the same time, and in the case of the combination timer operation unless, characterized by being configured to perform error display with the operation start time and operation stop time to disable and the timer operation is set to the same time.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a side view showing a schematic structure of a fan convector as an air conditioner to which the present invention is applied, FIG. 2 is an operation section, and FIG. 3 is an operation flowchart of the timer operation apparatus of the present invention.
[0009]
First, the configuration of the fan convector will be described with reference to FIG. 1. Reference numeral 1 denotes an outer case, an air suction port 3 having an air filter 2 attached to the front surface, and a hot air outlet 4 at a lower portion thereof. An operation unit 10 is disposed on the top plate of the outer case 1.
[0010]
Further, a heat exchanger 6 for heating is configured by meandering and disposing a finned pipe 5 for heat exchange in the center of the machine with respect to the air inlet 3. A heating on / off valve 27 (thermal valve) for controlling the flow rate of the hot water supplied to the heat exchanger 6 is attached to the upstream pipe line 26 of the finned pipe 5 constituting the heat exchanger 6. The end thereof is connected to a heating forward line (not shown) of a heat source machine that forms circulating hot water via an inlet plug 7, and hot water having a temperature higher than that of the hot water supply part of the heat source is supplied to the heat exchanger 6. On the other hand, the end of the downstream pipe line 28 of the finned pipe 5 is heated through the outlet plug 8 (disposed on the back side of the inlet plug 7). The hot water connected to the pipe line (not shown) and having finished the heat exchange is collected by the heat source unit.
[0011]
A fan motor 9 as a blower is disposed below the back side of the heat exchanger 6. During heating operation, the outside air sucked into the machine from the air suction port 3 through the air filter 2 by the fan motor 9 is heat exchanger. 6, the air is heated to a predetermined temperature and blown out of the device from the hot air outlet 4 through the air passage 24. A control board 25 for controlling the heating operation is mounted on the bottom of the machine.
[0012]
Next, the operation unit 10 of the fan convector will be described with reference to FIG. 2. In the figure, 11 is an operation switch for instructing the start and stop of the heating operation, and lights up in green during the heating operation. Reference numeral 12 denotes a wind speed switch for switching the speed of the warm air blown out of the device from the warm air outlet 4, and the corresponding wind speed lamp 18 (either automatic, strong or weak) is lit.
[0013]
Reference numeral 13 denotes an “ON” timer switch as an “ON” timer mode setting means for reserving the start of the heating operation, and reference numeral 14 denotes an “OFF” timer switch as an “OFF” timer mode setting means for reserving the stop of the heating operation. When the device is set to the “ON” timer mode by pressing the “ON” timer switch 13, the “ON” timer lamp 19 is lit, and when the “OFF” timer switch 14 is pressed, the device is set to the “OFF” timer. When the mode is set, the “OFF” timer lamp 20 is turned on. When both the “ON” timer switch 13 and the “OFF” timer switch 14 are operated, the device is set to the combination timer mode, and the “ON” timer lamp 19 and the “OFF” timer lamp 20 are turned on.
[0014]
Reference numeral 15 denotes a time changeover switch for selecting the start time and stop time of the timer operation, and 16 and 17 are time setting switches as time setting means. In order to set the timer operation, first, an “ON” time or “OFF” time is selected by the time selector switch 15. At this time, the corresponding time lamp 21 (current time, “on” time, or “off” time) is turned on. Next, the time setting switch 16 or 17 is operated to set the time corresponding to the time lamp 21 that is lit. That is, the operation start time can be set by selecting “ON” time, and the operation stop time can be set by selecting “OFF” time. When the time is set, the set time is displayed on the 7-segment display unit 23 for a predetermined time (for example, 5 seconds), and then automatically returns to the display of the set room temperature and the current room temperature again. .
[0015]
Incidentally, when the operation mode, the time-setting switch 16 and 17 are used as room temperature adjustment switch for temperature setting.
[0016]
Next, the control of the timer driving device of the present invention will be described based on the operation flowchart shown in FIG.
[0017]
The timer operation device of the present invention is controlled by a microcomputer (not shown) as operation control means mounted on the control board 25 based on the above-described switch setting for timer operation.
[0018]
When the operation switch 11 of the operation unit 10 is operated and the device enters the operation mode, the processing of the timer routine shown in FIG. 3 is periodically executed. At this point, it is assumed that the various switch settings for the timer operation have been completed.
[0019]
First, in step 30, it is determined whether the device is set to the “ON” timer mode. If it is in the “ON” timer mode, the input time is compared with the current time in step 31. If they do not match, the program processing exits this timer routine (return). When this process routine is repeatedly executed and the current time reaches the entry time, the operation start process of step 32 is executed, and the heating operation is started. Thus, in the “ON” timer mode, the heating operation is started at the operation start time set by the time setting switch 16 or 17.
[0020]
Next, if it is determined in step 30 that the device is not in the “ON” timer mode, it is determined in step 33 whether the “OFF” timer mode is set. If it is in the “OFF” timer mode, the OFF time and the current time are compared in step 34, and if both times do not match, this timer routine is exited. As a matter of course, the heating operation is performed while this processing routine is repeatedly executed. When time passes and the current time reaches the cut-off time, an operation stop process in step 35 is executed, and the heating operation is stopped. Thus, in the “off” timer mode, the heating operation is stopped at the operation stop time set by the time setting switch 16 or 17. In the processing routine of the above-mentioned “ON” timer mode and “OFF” timer mode, the comparison check of the ON time and the OFF time (check of the same time setting) is not performed at all. Therefore, even if the same time setting is made, a predetermined timer operation process (the process of step 32 or step 35) is executed.
[0021]
If it is determined in step 33 that the device is not in the “OFF” timer mode, step 36 is executed to determine whether it is in the combination timer mode. When not in the combination timer mode, that is, in the case of normal operation, this timer routine is exited as it is. If it is determined in the mode determination of step 36 that the combination timer mode is selected, the next time 37 compares the on time and the off time, and if the same time is set, it is determined that the time is set incorrectly. Step 38 is executed and an error is displayed on the operation unit 10. The display form of the error may be, for example, an E display by the 7-segment display unit 23 or a blinking display of the “ON” timer lamp and the “OFF” timer lamp.
[0022]
When the user recognizes the time setting error by the error display and resets it to a different time, the comparison determination at step 37 is “NO”, and step 39 is executed to cancel the error display.
[0023]
In the next step 40 determination process, if it is determined that the current time has reached the entry time, step 41 is executed and the heating operation is started. Thereafter, when it is determined in step 42 that the current time has reached the cut-off time, step 43 is executed and the heating operation is stopped. Thus, in the combination timer mode, the heating operation is started at the operation start time set by the time adjustment switch 16 or 17, and the heating operation is stopped at the operation stop time. However, the operation start time and the operation stop time are the same time. If set to , timer operation is not executed and an error is displayed.
[0024]
【The invention's effect】
As described above, according to the present invention, in the case of the timer operation, when the operation start time and the operation stop time are set to the same time, in the case of the “on” timer operation and the “off” timer operation, an error occurs. real and upper that can execute the respective predetermined timer operation without, for error display without performing the timer operation only if the combination timer operation, the user misconfiguring time in the case of the combination timer operation In this case, the operability at the time of setting in the case of “ON” timer operation and “OFF” timer operation is improved, and usability can be improved .
