Abstract

PURPOSE:To provide a control unit of an air conditioner capable of simultaneously operating or stopping the air conditioner using a general remote control switch even during the simultaneous operation control using a remote control switch by releasing the simultaneous operation by providing releasing means for releasing the simultaneous operation/stop move operation. CONSTITUTION:Release means 16a and 16b are connected to input terminals IO(a) and IO(b). In a case where a release switch 17a is closed (ON), the input level on the side of the release switch 17a of an OR gate 19a becomes a power source high level. Therefore, the output of an OR gate 19a becomes a high level despits the input level at the input terminal connected to the first switch 9. Hence, irrespective of ON/OFF of the first switch 9 of the remote control switch, the level of the input terminal IO(a) of the control means 4a is high. Therefore, the simultaneous operation/stop using a remote control switch 8 cannot be carried out. That is, the operation/stop is carried out by use of a drive switch 5a on the remote controller 2a. The same can apply to the case of the release means 16b of the second air conditioner unit 7b.

Problems to be Solved by the Invention However, with the above configuration, air conditioners with this configuration are installed in small and medium-sized buildings that have a variety of tenants, etc., and the manager of the building For example, a remote switch can be used to set the
The air conditioners will be turned on all at once at 1:30 p.m., and shut down at 8 p.m. However, if one tenant's operating hours are from 10 a.m. to 8 p.m., or if the regular holiday is different, or if the business is temporarily closed, the air conditioner may be turned on even when it is not in use. However, there was a problem in that the user had to pay extra for electricity.

In view of the above-mentioned problems, the present invention provides a control device for air conditioners that can cancel the simultaneous operation control even when the simultaneous operation is controlled by a remote switch, and start/stop the air conditioner using an ordinary remote control.

Means for Solving the Problems In order to solve the above problems, the air conditioner control device of the present invention allows the air conditioners to be started/stopped as usual by the air conditioner remote control even when the air conditioners are set to start/stop all at once using a remote switch. This device is equipped with a canceling means for canceling the simultaneous operation/stop setting of remote switches.

Effects According to the present invention, with the above-described configuration, even if the remote switch is used to set the air conditioners to operate/stop all at once, the release means can release the setting. As a result, the air conditioners can be started/stopped individually using the remote control as usual, and by setting the release setting in advance, the air conditioner can be removed from simultaneous operation/stop control using the remote switch. In addition, the user of the air conditioner can arbitrarily control the air conditioners by operating/stopping them all at once, or operate them with a remote control when the air conditioners are not under control, using the release means.

Embodiment Hereinafter, a control device for an air conditioner according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows the configuration of the release means of the air conditioner control device of the present invention. FIG. 2 is a control configuration diagram of the air conditioner of the present invention. Portions that are the same as those in the conventional example are designated by the same numbers, and detailed description thereof will be omitted.

・Connected to. The configuration of the release means of this embodiment will be explained based on FIG.

FIG. 1 is a block diagram of the release means of the first air conditioning unit 7a, where 17a is a release switch connected to the power supply vDD, one is connected to the pull-down resistor 18 &, and the pull-down resistor 18a is grounded.

19a is a two-man powered OR gate, one input terminal is connected to the connection point between the release switch 17a and the pull-down resistor 18a, the other input terminal is connected to the first switch 9 of the remote switch 8, and the output terminal is The release means 1 and 6b on the second air conditioner unit 7b, which are connected to the input terminal 0(a) of the remote control control means 4a, have a similar configuration.

The operation of the air conditioner control device configured as described above will be explained below.

In the first air conditioner unit 7a, the operation of each part except for the release means 16a is the same as that of the conventional example, so a description thereof will be omitted.

First, when the release switch 17a on the remote control 2a is not turned on (OFF), the input level on the switch side of the OR gate 19a becomes L level because the input is pulled down by the pull-down resistor 18a, and the OR gate 19
As for the output of a, the input level of the connected input terminal of the first switch 9 is directly outputted to the output terminal.

That is, when the release switch 17a is OFF, the input terminal of the control means 4a! . The input level input to (a) is the same as in the conventional example when the first switch 9 is OFF.
When it is ON, it is H level, ONI, and when it is ON, it is L level. Therefore, by using the first switch 9, simultaneous operation/stopping can be performed from a distance.

Next, when the release switch 17a is turned on (ON), the input level of the OR gate 19a on the release switch 17a side becomes the power supply "H" level. Therefore, the output of the OR gate 19a becomes H level regardless of the input level of the input terminal connected to the first switch 9. ) input level ranges between H levels, and simultaneous operation/stopping using the remote switch 9 is not possible. That is, it is operated/stopped using the operation switch 6a on the remote controller 2a. The same applies to the release means 16b of the second air conditioner unit 7b.

As described above, according to this embodiment, the remote control 2a.

2b, . . . Above are canceling means 17a, 17b for canceling simultaneous operation/stopping of air conditioners by the remote switch 9.

By providing . . . , the release means 17a, 17b, old and
・You can start/stop the air conditioner individually with the remote control as usual, and if you set it to cancel in advance, you can remove that air conditioner from simultaneous start/stop control using a remote switch, so as mentioned in the problem with the conventional example. -The time period for simultaneous operation control is to start at 7:30 a.m. every morning and stop at 8 p.m.
A tenant's air conditioner is used from 10 a.m. to 8 p.m.
Even if the office is temporarily closed, you can turn on the release switch and set it to release, so that the air conditioners of unoccupied tenants will not be operated all at once. The practical effect is extremely large, since the user does not have to pay for electricity.

In this embodiment, the canceling means is configured as a circuit using an OR gate, but it goes without saying that the same effect can be obtained even if the control means is a microcomputer and configured as a program.

Effects of the Invention As described above, the present invention is capable of operating/stopping multiple air conditioners at the same time from a distance, or operating an air conditioner with a remote control, which is provided separately from a remote controller that remotely operates an air conditioner. By providing a release means on the remote control of each air conditioner to cancel the simultaneous operation/stop of the air conditioners even when the remote switch is set to start/stop individually, each air conditioner can be controlled by the remote switch. Since the user of the air conditioner can arbitrarily remove the simultaneous operation/stop control as needed, it is possible to control the operation of a wide range of air conditioners without waste.
