Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner for conditioning indoor air using a refrigeration cycle, and more particularly, to an air conditioner capable of setting an operation start time.

[0002]

2. Description of the Related Art An air conditioner (hereinafter referred to as an "air conditioner") for controlling indoor air by cooling, dehumidifying, and heating operations.
The operation start time and the operation end time can be set by a timer. For example, if an operation start time is set in advance, the room can be brought into a desired air-conditioning state before entering the room where the air conditioner is installed.

[0005] The setting of the operation start and the operation end by such a timer is generally performed by a remote control switch. For example, the operation start time and the air conditioning condition (operation mode, set temperature, etc.) are set in the remote control switch. When the operation start time is reached, the operation mode and the set temperature are output to the air conditioner together with the operation start signal.

[0004] The air conditioner starts operation based on an operation start signal from the remote controller and the like. Also, the remote control is provided with a temperature sensor that detects the indoor temperature,
In some cases, the set temperature is compared with the room temperature, and the operation is started earlier in advance so that the room is set to the set temperature at the set operation start time. Thereby, the room can be brought into a desired air-conditioning state at the set operation start time.

[0005] By the way, it is common practice to stop the air conditioner that has started operation by setting a timer by directly operating a stop switch of a remote controller. For this reason, there is a problem in that the user forgets to set the operation start time of the air conditioner by the timer, and the air conditioner continues to operate when the user goes outside for a long time.

[0006] Operating the air conditioner without anybody in the room for a long time leads to waste of energy. Also,
Recent air conditioners try to reduce the operating cost by controlling the capacity based on the indoor temperature and the set temperature, but operating the air conditioner unnecessarily leads to an increase in the operating cost.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and forgotten to set the timer operation or to operate the air conditioner for a long time. It is an object of the present invention to propose an air conditioner that prevents the air conditioner from continuing to operate unnecessarily when it does so, and saves energy and increases operating costs.

[0008]

The invention according to claim 1 is
An air conditioner driven based on an operation signal corresponding to a set operation condition to perform indoor air conditioning, wherein operation detection means for detecting whether or not the operation signal is input; and Operation detection means for detecting whether there is, and measurement means for measuring the duration of the non-detection state of the operation detection means when the operation detection means is detecting the operation state,
An operation stopping means for stopping the operation when the measurement result of the measuring means has reached a predetermined time, and a remote control means for remotely controlling the air conditioner by wireless are provided.

According to the present invention, the time since the last operation signal was detected in the operating state by the remote control means that remotely controls the apparatus by wireless is measured by the measurement means. Then, when the measurement time reaches a predetermined time set in advance, the operation is stopped by the operation stopping means.

In general air conditioners, a driving operation is performed using a remote control switch or the like. In many air conditioners, operation / stop is performed based on a signal sent from a remote control switch. . In many cases, a stop signal is transmitted from a remote control switch.

Here, when the setting or change of the operating condition for a long time is not performed, it is conceivable that no one is in the air-conditioned room. In particular, it is conceivable that the setting of the operating conditions is not changed in about several hours,
In the above, since the temperature of the outside air also changes, it is conceivable to change the set temperature, the air volume, and the wind direction.However, if no operation is performed within this time, it is considered that no one is in the room, To stop.

When the operation is started by a timer reservation or the like, it is possible to enter or leave the room after starting the air conditioning. However, if no operation is performed for one day (24 hours) or more, the room is air conditioned. Stop driving because you may have forgotten to be there.

As described above, the remote control means such as a wireless remote control switch is provided with the function of preventing forgetting to turn off, so that the air conditioning operation in the room is forgotten, or the user goes to a remote place to stop the operation. Even if a state that cannot be performed occurs, after a predetermined time elapses,
Since the operation is reliably stopped, it is possible not only to save energy, but also to suppress uneconomical effects caused by continuing air conditioning in a room where no one is present.

If the air conditioner is replaced with a remote control switch having a forget-to-turn function, the air-conditioner can easily have the forget-to-turn function at low cost.

According to a second aspect of the present invention, there is provided an air conditioner which operates based on an operation signal corresponding to a set operation condition to perform indoor air conditioning, and determines whether or not the operation signal is input. Operation detecting means for detecting the operation, operation detecting means for detecting whether or not the vehicle is in operation, and measuring the duration of the non-detection state of the operation detecting means when the operation detecting means detects the operating state. Measuring means, operation stopping means for stopping operation when the measurement result of the measuring means reaches a predetermined time, and reservation means for starting air-conditioning operation at a preset time, wherein the measuring means It operates when the operation is started based on the means.

According to the present invention, when operation is started at the time set by the reservation means, forgetting to cut off is prevented. When the operation is started with the timer reserved, there is a high possibility that no one is in the room to be air-conditioned. In particular, when the user forgets to make a timer reservation, he will not notice that the air conditioner is operating. For this reason, when a timer is reserved, when no operation related to the operation is performed even after the lapse of a predetermined time, the operation is stopped to surely prevent unnecessary air conditioning operation while saving energy. can do.

2 resets the timer every time an operation signal is input from
The air conditioner 10 is provided with a so-called “forgetting to stop turning off” function, in which a stop signal is sent to the indoor unit 12 of the air conditioner 10 to stop the operation of the air conditioner 10 when the time t measured by the timer reaches a preset set time T. I have. In addition, the time for stopping the air conditioner 10 by the cut-off prevention function may be set arbitrarily, but in the present embodiment, the set time T is set to 25 hours as an example.

The operation of this embodiment will be described below.

In the air conditioner 10, operating conditions such as an operating mode, a set temperature, a wind direction, and an air volume are set by operating the remote controller 120, and these operating conditions and the run / stop button 1 are set.
When an operation signal corresponding to the operation of 26 is transmitted from the remote controller 120, the operation is started according to the operation signal. As a result, the room in which the indoor unit 12 of the air conditioner 10 is provided is set to a desired air condition according to the operation of the remote controller 120.

The operation of the air conditioner 10 is stopped when the operation / stop button 126 of the remote controller 120 is operated during the air-conditioning operation and an operation signal for instructing a stop is input from the remote controller 120.

On the other hand, the remote controller 120 can operate the air conditioner 10 by timer reservation. In this timer reservation, when operation conditions such as an operation mode set temperature, a wind direction and an air volume are input together with the operation start time, the reservation time is stored together with these operation conditions. After that, when it is confirmed that the time reserved by the timer circuit 166 has come, an operation signal for instructing the start of operation is sent to the indoor unit 12 together with the automatically set and stored operating conditions. The indoor unit 12 of the air conditioner 10
When this operation signal is received, the operation is started under the operation conditions according to the operation signal. As a result, the room can be automatically brought into a desired air-conditioning state at a desired time.

The remote controller 120 of the air conditioner 10
Is provided with a function for preventing forgetting to cut. With reference to the flowchart shown in FIG. This flowchart is executed in parallel with the normal processing of the remote controller 120.

In this flowchart, it is confirmed whether or not the air conditioner 10 has been started in the first step 200, and when the air conditioner 10 starts operating, the flow proceeds to step 202 to reset / start the timer for preventing turning off, and Of the non-operation time t is started.

In the next step 204, the user operates the temperature setting buttons 128 A and 128 B provided on the operation unit 162 and the various operation buttons provided on the operation panel 136, and determines whether an operation signal has been input from the operation unit 162. Confirm whether or not. The fact that an operation signal is input from the operation unit 162 means that a person in the room being air-conditioned
Since it is determined that the operation signal has been operated, it is confirmed that an operation signal has been input (Yes in step 204), and the process returns to step 202 to reset / start the forgetting prevention timer again, and to reset the non-operation time t again. Start measurement.

In step 206, the air conditioner 10
Check whether or not has stopped. For example, when the previous operation signal from the operation unit 162 is a signal for stopping the operation, the operation signal is transmitted from the remote controller 120 to the indoor unit 12, and the air conditioner 10 is stopped. If the air conditioner 10 is stopped (Yes in step 206), the process proceeds to step 208, in which the timer for preventing turning off is stopped, and this flowchart ends.

When no operation signal is input from the operation unit 162 and the air conditioner 10 is not stopped (when a negative determination is made in steps 204 and 206), the process proceeds to step 210. The non-operation time t measured by the timer for preventing turning off is set to a preset time T (25 in this embodiment as an example in the present embodiment).
Time) to determine whether the non-operation time t has exceeded the set time T.

If the remote controller 120 has not been operated for a long time, the air conditioner
Is determined to be operating. In particular, it is conceivable that no operation is performed for about several hours, but if the air conditioner 10 has been operating for more than half a day (12 hours), and even more than one day, no operation is performed, It is determined that there is no one.

For this reason, when the non-operation time t exceeds the set time T and an affirmative determination is made in step 210, the process proceeds to step 212 and the indoor unit 1 of the air conditioner 10
2 outputs an operation signal instructing a stop. Air conditioner 10
When the operation signal for instructing the stop is input from the remote controller 120, the indoor unit 12 stops operating.

As described above, the air conditioner 10 is stopped when air-conditioning is continued for a predetermined time or more in a room where no one seems to be present. For this reason, for example, even if the user forgets to turn off the air conditioner 10 or forgets to set the reservation timer when leaving the room where the indoor unit 12 is installed for a long time (one day or more), When the air conditioner 10 is operated for a predetermined time (set time T), it automatically stops.

Therefore, the air conditioner 10 has been
It is possible to suppress not only waste of energy due to continuous operation of the air conditioner but also cost caused by operating the air conditioner 10.

The air conditioner 10 may be prevented from being forgotten to be turned off only when the timer is reserved. When the timer is reserved, there is a possibility that no one is in the room when the air conditioner 10 starts operating. Further, when the user forgets to make a timer reservation, he or she does not notice that the air conditioner 10 is operating, and it is highly likely that the air conditioner 10 will be operated for a long time or several days.

In this case, stopping the air conditioner 10 by the function of preventing the air conditioner 10 from being left unnecessarily can surely prevent the air conditioner 10 from continuing to be operated unnecessarily. Can be prevented from rising.

Also, the set time T for preventing forgetting to turn off
May be set arbitrarily. Further, the set time T for preventing the user from forgetting to turn off may be set separately when the operation is started by directly operating the operation / stop button 126 of the remote controller 120 and when the operation is started by timer reservation. good. For example, the set time T when the operation is started by timer reservation is set to 25 hours, and when the operation is started by directly operating the operation / stop button 126, the time is set to about half of 12 hours. good.

In this embodiment, the remote controller 120
Although the function of preventing the user from forgetting to erase is provided, the microcomputer 74 of the indoor unit 12 may have the function of preventing the user from forgetting to erase. In this case, each time an operation signal corresponding to a button operation of the operation unit 162 is input from the remote controller 120 to the receiving circuit provided on the display substrate 82, the timer for resetting to prevent turning off is reset /
Just start it.

The present embodiment shows an example of the present invention, and the present invention can be applied to all air conditioners for indoor air conditioning. Further, the set time for preventing forgetting to turn off may be arbitrarily determined according to the indoor use in which the air conditioner performs air conditioning.

[0070]

As described above, according to the present invention, when the operating conditions and the like are not set or changed during the preset time, it is determined that there is nobody in the room to be air-conditioned and the operation is stopped. As a result, the operation is not continued for a long time in a room where no one exists, meaning that energy can be saved and a rise in cost caused by operating the air conditioner can be suppressed. In particular, when the timer is reserved, the user may not be aware of the fact that the indoor air conditioning is being performed, but even in such a case, the excellent effect that the operation of the air conditioner is reliably stopped is provided. can get.
