Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to timer-activated operation of an air conditioner.

Conventional technology The timer activation methods for conventional air conditioners can be roughly divided into two: ``operation start time setting method,'' which starts the operation at a set time, and ``operation start time setting method,'' which starts the operation at a preset time so that the room temperature reaches the set temperature at the set time. Setting method”
It can be divided into

Among these, in the "set room temperature arrival time setting method", it is necessary to operate the air conditioner in advance before the specified set room temperature arrival time, but depending on the room where the air conditioner is installed or the purpose. There was no control to change the air volume of the indoor blower of the air conditioner.

Problems that the invention attempts to solve: Therefore, use a turn-on timer in the bedroom and set the time (=
If you set the air conditioner's timer so that the room temperature reaches the set temperature at the time you wake up, the air conditioner will start operating at the normal airflow rate of the indoor fan before the time you wake up, which can cause problems such as waking up due to noise and problems such as waking up when you are in the living room. When using a timer, the air conditioner will operate at the normal indoor fan air volume even though no one is in the room before the set time, which means that the air conditioner will operate inefficiently. Therefore, some kind of response was desired.

Means for Solving the Problems In view of the above problems, input the purpose of the room used, such as living room, bedroom, etc., into the main body of the air conditioner using some method (the input method is omitted as it is not the gist of the present invention). ) The air volume (=noise) of the indoor fan during preliminary operation, which is performed before the set room temperature is reached, is changed based on the intended use of the room.

Effect As mentioned above, if the room is used in accordance with the intended use of the room, for example, if it is a bedroom, the air conditioner is operated at a low noise and small air volume, so that the user is not woken up by the noise of the air conditioner before the set room temperature is reached. You can get a good night's sleep without worrying about it. Also, if you are in the living room, if you input the time when you start using it into the air conditioner as the time when the set room temperature is reached, there will be no one in the living room until the set room temperature is reached. Since the noise generated by the indoor blower of the air conditioner during pre-operation can be ignored, it only needs to be louder than the normal operating noise, and the blower air volume can be increased accordingly, resulting in more efficient operation. bring about.

Embodiment The type of room being used is input as the living room/bedroom classification using the remote control device of the air conditioner. However, since this input method is not the gist of the present invention, input using an operation switch or other methods may be used.

If this input information is for the living room, the air volume of the indoor blower of the air conditioner that is running in advance until the set room temperature setting time is increased to the maximum, and the operating state is the most energy efficient although the noise is loud. .

In addition, in the bedroom, the air volume of the blower is minimized to minimize the noise from the indoor blower of the air conditioner that is running before the set room temperature time so as not to disturb a good night's sleep. Furthermore, when the set time has elapsed, the indoor blower air volume is returned to normal control.

Effects of the invention If the device is used in a bedroom, the temperature should be comfortable when you wake up, and it should be as quiet as possible while you are sleeping. However, once you wake up and get active, you won't be bothered by the noise normally generated by the air conditioner, and on the other hand, the general theory is that if your energy efficiency is good, a little noise won't bother you. Therefore, according to the present invention, the noise from the air conditioner is low enough not to disturb a good night's sleep during the pre-operation until the time when the set room temperature is reached, and when waking up, the room temperature is kept at the set temperature by the pre-operation before the time when the set room temperature is reached. Since the device reaches the set time, it is possible to promise a refreshing wake up, and since the blower returns to normal control after the set time is reached, it has the effect of improving the energy effect in the active state after the set time (waking up). It is. In addition, in the case of a living room, no one is in the room until the time when the room is started to be used. Also, it is a general idea that the set room temperature should be reached at the time of starting use. Therefore, according to the present invention, during preliminary operation until the time when the set room temperature is reached, the air volume of the indoor blower of the air conditioner is adjusted to make noise that can only be tolerated under the condition that no one is present, so that the efficiency of the equipment can be maximized. Increase to the maximum. As a result, the energy efficiency during operation is maximized, and as shown in FIGS. 1 and 2, the time required for the room temperature to reach the set temperature is minimized, and the energy expended during pre-operation is minimized. However, after the set time, that is, when a person starts using the room, the noise becomes normal, so the user can perceive it as having the same noise level as the conventional control.

[Brief explanation of drawings]

Figures 1 and 2 are time charts showing the time it takes for the room temperature to reach the set temperature due to the difference in air volume between the indoor side blowers of the air conditioner, Figure 3 is a flow chart showing the control details of the present invention, and Figure 4 is a flow chart showing the control details of the present invention. The figure is a schematic control block diagram of the present invention.

Claims (1)

[Claims] 1. In a timer activation method in which a pre-operation is performed before the set time so that the room temperature reaches the set temperature at the set time, the air conditioner is activated during the pre-operation before the set time depending on the purpose of the room in which the air conditioner is installed. A timer start operation control method for an air conditioner that changes the air volume of the indoor side blower of the machine.
