Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention provides a start-up system that delays the restart of a compressor when, for example, a cooling operation mode is switched to a blower operation mode or a heating operation mode. A compressor that is driven in response to a signal, an operation mode switching means that switches between operation modes, and a switching operation by the operation mode switching means that is in a first state that requires the compressor to be stopped or a first state that requires the compressor to be stopped. a switching state determining means that outputs a standby signal only when the first state is determined, and restarts the compressor for a set time in response to the standby signal; The present invention relates to an operation control device for an air conditioner including an operation standby means for stopping the operation.

(Prior Art) As the above-mentioned operation mode switching means, the one shown in, for example, Japanese Utility Model Application Laid-Open No. 61-142248 is known. FIG. 4 is a perspective view of the conventional remote control device. In this diagram,
01 is the operation mode switching means, and the slide groove 0
2 is provided with a slide switch 03 that can be slid freely, and by sliding the slide switch 03, for example, automatic operation mode, cooling operation mode,
It is configured to switch to a predetermined operation mode such as a dry operation mode or a heating operation mode.

(Problems to be Solved by the Invention) However, in the case of the conventional example, for example, when heating operation is performed in automatic operation mode and the operation mode is switched to artificial heating operation mode, Although it performs the same heating operation, as it passes the cooling operation mode position, a standby signal is output, the compressor is stopped for the set time, and the heating operation is interrupted for the set time. However, there was a drawback that comfort was compromised.

In addition, when attempting to switch from cooling operation mode to dry operation mode and accidentally switching to heating operation mode, a standby signal is output as soon as the heating operation mode position is reached, and the same situation as described above occurs. There was a drawback that comfort was compromised.

Furthermore, even in the case of a type that operates with a push button switch instead of a slide switch as described above, if heating operation is performed in automatic operation mode, it is difficult to switch the operation mode to artificial heating operation mode. If you accidentally operate the push button switch for cooling operation mode or dry operation mode, and you press it again, a standby signal will be output due to the erroneous operation, and the comfort will be affected as described above. There was a drawback that the quality was impaired.

The present invention has been made in view of the above circumstances, and an object of the present invention is to avoid unnecessary interruptions in driving when switching driving modes and to improve comfort.

(Means for solving the problems) In order to achieve such an object, the present invention has the following features:
In the operation control device for an air conditioner described at the beginning, when the operation mode is switched by the operation mode switching means 4, the holding means 17 causes the switching state determination means 15 to make a determination after a set time has elapsed after the switching operation. Adopt the structure of being prepared.

(Function) According to the above configuration, in the switching operation by the operation mode switching means 4, for example, switching from the heating operation state in the automatic operation mode to the heating operation state in the artificial heating operation mode, or switching from the cooling operation mode to the dry operation mode Even if the compressor 12 enters the first state that requires the compressor 12 to be stopped when the compressor 12 is unexpectedly operated to the heating operation mode when switching to the heating operation mode, the compressor 12 will not return to the first state after the set time has elapsed. Unnecessary output of standby signals can be avoided as long as it is not used.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings. FIG. 1 is a block diagram showing a schematic configuration of the present invention, and FIG. 2 is a circuit block diagram of an operation control device for an air conditioner according to an embodiment of the present invention.

In these figures, reference numeral 1 denotes an infrared remote control device, which includes an operation mode switching means 4 consisting of a slide switch 2 and a slide groove 3, an operation switch 5, and a wind direction switch for changing the blowing direction of temperature-controlled air. A swing switch 6 for driving or stopping the drive motor of the control board is provided.

By sliding the slide switch 2, the operation mode switching means 4 switches between automatic operation mode (A position), cooling operation mode (C position), dry operation mode (D position), and
It is designed so that it can be switched to each heating operation mode (H position).

A command signal transmitted from the remote control device 1 is input to the indoor control section 7 provided in the air conditioner main body, and in response to the command signal, the indoor control section 7 communicates with the outdoor control section 8 and the indoor control section 7. A start signal is output to the inner driver 9.

The indoor driver 9 outputs a drive output to the indoor fan motor 10 in response to the activation signal;
It is designed to drive an indoor fan motor 10.

The outdoor side control section 8 outputs a predetermined starting signal to the outdoor side driver 11 in response to the starting signal, and in response to the starting signal, the outdoor side driver 11 controls the compressor 12 and the outdoor side fan motor. 13 and the four-way switching valve 14 respectively,
It is designed to drive them.

As shown in FIG. 1, the indoor control section 7 is equipped with a switching state determining means 15, an operation standby means 16, and a holding means 17.

The switching state determining means 15 determines whether the switching operation by the operation mode switching means 4 is a first state that requires stopping the compressor 12 or a second state that does not require stopping, and determines the first state. It is designed to output a standby signal only when the

The operation standby means 16 starts a standby timer in response to the standby signal from the switching state determining means 15, and operates the compressor 12 only for a set time (for example, 3 minutes) until the standby timer times up. It is supposed to stop restarting.

In the holding means 17, the operation mode switching means 4
When the operation mode is switched, a holding timer is started in conjunction with the switching operation,
The determination timing is delayed for a set time (for example, 5 seconds) until the holding timer times up, and the switching state determining means 15 performs the determination after the set time has elapsed.

Next, the operation of the above-mentioned indoor side control section 7 will be explained using the flowchart shown in FIG. 3.

After operation switch 5 is turned on (S1),
Determine whether the standby timer is counting, that is, whether the compressor 12 is on standby and has stopped restarting (S2), and if the standby timer is not counting, drive the compressor 12, and then: step
Did the retention timer expire after moving to S4?
That is, it is determined whether or not the time has expired.

In step S2, when it is determined that the standby timer is counting, the compressor 12
After driving (S5), the process moves to step S4.

In step S4, when it is determined that the hold timer has not exceeded, that is, when the hold timer is in operation or not in operation, the process moves to step S6, and the remote control device 1 (not shown in the figure) is activated. It is determined whether the operation mode has been switched by the operation mode switching means 4 of the remote control.

Here, if it is determined that the driving mode has not been switched, the process returns to step S2, and conversely, if it is determined that the driving mode has been switched,
The process moves to step S7, sets and starts a holding timer, and then returns to step S2.

When it is determined in step S4 that the holding timer has exceeded, that is, it has counted up after starting, the process moves to step S8, where the holding timer is cleared and reset.

After that, it is determined whether the operation mode set on the remote control device 1 matches the operation mode stored in the operation mode determination area of the memory (S9), and if they match, the step If they do not match, the process moves to step S10, and the operation mode of the remote control device 1 is moved to the operation mode determination area of the memory in place of the previously stored operation mode.

Thereafter, the switching state determining means 15 determines whether the switching operation by the operation mode switching means 4 is
A standby signal is generated only when the first state is determined, and whether the compressor 12 is in the first state that requires stopping or the second state that does not require stopping, that is, whether the compressor 12 starts or stops. is output, and the operation standby means 16
The standby timer is set and started (S12), and then the process returns to step S2.

Step S4, Step S6 for causing the switching state determining means 15 to make a determination after a set time has elapsed after the switching operation when the driving mode is switched by the driving mode switching means 4;
The holding means 17 performs the processing consisting of step S7 and step S8.

In the above embodiment, an air conditioner of the type in which the operation mode is switched by the remote control device 1 is shown, but for example, there may be a type in which the air conditioner body is provided with an operation mode changeover switch, or It can be applied to various types of air conditioners such as those used in combination, and can also be applied to those using push button switches instead of slide switches.

Further, the present invention includes, for example, an air conditioner exclusively for cooling that has a cooling operation mode and a blower operation mode, and switches the compressor 12 between a driving state and a stopped state when switching between the two operating modes, Similarly, the present invention can be applied to an air conditioner exclusively for heating, which has a heating operation mode and a blower operation mode.

(Effects of the Invention) As described above, according to the present invention, when a driving mode switching operation is performed, the holding means 17 delays the set time from that point until the switching state of the driving mode is determined. Because it has
Just passing through when switching driving modes, etc.
Even if the compressor unexpectedly enters an operating state (first state) that requires it to be stopped due to an incorrect operation, the compressor must have passed within the set time or returned to its normal operating position during the set time. Due to modifications etc.
If the first state is not reached after the set time elapses, the standby signal is not output from the operation standby means 16,
This makes it possible to avoid unnecessary interruptions in heating operations, etc., and improve comfort.
