Abstract

PURPOSE:To prevent a room temperature from increasing after stopping of either a cooling or a dehumidifying operation and to improve a dwelling comfortability. CONSTITUTION:When an operation switch 81 at an inputting operation part 2 is operated, motors M1 to M3 are controlled for their operations in such a manner that a room temperature detected by a thermistor 3 becomes a target temperature set by a room temperature setting switch S3 in response to any one of operating modes of a cooling, a dehumidifying or a heating set by a mode setting switch S2. When a timer switch S4 and a window releasing switch S6 are operated during a cooling operation or a dehumidifying operation, a limited time set by the timer switch S4 elapses and at the time when either the cooling operation or the dehumidifying operation is stopped, a window releasing motor M4 is driven to release the window. In this way, it is possible to prevent a rapid increasing of room temperature after stopping of the cooling operation or the dehumidifying operation and to improve a dwelling characteristic.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner capable of at least cooling.

[0002]

2. Description of the Related Art In an air conditioner, there is a risk that health may be impaired if the air conditioner is left unattended during sleep, especially when the person is asleep. Is configured. However, in such a configuration, the room temperature suddenly rises immediately when the cooling operation is stopped, so that there is a problem that when the user is not completely asleep, the cooling operation must be restarted to suppress the sleepiness. is there.

As another conventional technique for solving such a problem, when the operation mode for sleeping is set in the air conditioner, the room temperature is gradually raised and the air conditioner is stopped after the preset time has elapsed. The configuration shown in FIG. With such a configuration, it is reduced that the user's body gradually gets accustomed to a higher temperature as the room temperature rises and suddenly feels uncomfortable.

[0004]

In recent years, in order to improve the cooling and heating efficiency and to block noises, the airtightness of each room is increasing especially in an apartment house. Therefore, in the above-mentioned conventional technique, even if the temperature is sufficiently cool outdoors for sleeping, the room is closed, so that when the cooling operation is stopped, the temperature inside the room becomes considerably high.

An object of the present invention is to provide an air conditioner capable of improving habitability after the cooling operation is stopped.

[0006]

According to the present invention, in an air conditioner capable of performing at least cooling, an opening / closing means capable of opening / closing a window and the fact that the cooling operation of the air conditioner has stopped are detected. An air conditioner comprising: a driving unit that drives the opening / closing unit to open the window.

Further, according to the present invention, a temperature sensor for detecting an outdoor temperature is provided, and the driving means opens the window so that the indoor temperature becomes a comfortable temperature corresponding to the outdoor temperature detected by the temperature sensor. It is characterized by adjusting the amount.

[0008]

According to the present invention, when the cooling operation is stopped, the drive means drives the opening / closing means including a motor and an air cylinder to open the window. Further, preferably, an outdoor air temperature sensor is provided, and the degree of opening of the window is adjusted so that the indoor temperature does not drop too much in response to the outdoor air temperature detected by the outdoor air temperature sensor.

Therefore, even if the airtightness of the room is high, it is possible to prevent the temperature from rapidly increasing after the cooling operation is stopped, the habitability can be improved, and it is preferable to carry out the operation at bedtime. You can

1 is a block diagram showing the electrical construction of an air conditioner 1 according to an embodiment of the present invention, and FIG. 2 is a perspective view thereof. This air conditioner 1 includes an operation switch S of the input operation unit 2.
When 1 is operated, it is determined whether the operation mode of cooling, dehumidification or heating is set by the mode setting switch S2, and the temperature set by the temperature setting switch S3 and the room 4 detected by the thermistor 3 are detected. The compressor motor M1 and the outdoor and indoor fan motors M2 and M3 are drive-controlled in accordance with the difference from the room temperature. Thus
Cooling / dehumidifying or heating operation is performed so as to reach the desired room temperature set by the temperature setting switch S3.

Further, the input operation section 2 is provided with a timer switch S4, a sleep switch S5, and a window opening switch S6. In the control circuit 5, when the timer switch S4 is operated in the air conditioning operation state, the air conditioning operation is stopped when the time limit time has elapsed, and the timer switch S4 is operated in the state where the air conditioning operation is stopped. Then, the air conditioning operation is started when the time limit elapses. Furthermore, when the sleep switch S5 is operated, the target temperature set by the temperature setting switch S3 is increased by a predetermined temperature during the cooling operation, and is decreased by the predetermined temperature during the heating operation at every predetermined time. Update to the value. This makes it possible to prevent a sudden change in room temperature after the air conditioning operation is stopped.

Further, when the window opening switch S6 is operated during the cooling or dehumidifying operation, the control circuit 5 drives the window opening / closing motor M4 to open the window 6 when the cooling or dehumidifying operation is stopped. Introduce outside air into the room 4. That is, a gear 8 is fixed to the output shaft 7 of the window opening / closing motor M4, and the gear 8 is meshed with a rack rail 10 extending in the opening / closing direction 9 of the window 6. Therefore, by driving the window opening / closing motor M4, the window 6
Can be opened and closed.

By thus opening the window 6 after stopping the cooling or dehumidifying operation, even if the room 4 is highly airtight, it is possible to prevent a rapid rise in room temperature after the operation is stopped, and to improve the comfortability. Can be improved. In addition,
The respective switches S4 to S6 may be used in combination with each other. For example, if all the switches S4 to S6 are used together, until the time limit set by the timer switch S4,
The target temperature of the room temperature is increased by a predetermined temperature for each predetermined time, and the cooling or dehumidifying operation is stopped when the time limit time has elapsed, and the window 6 is opened.

FIG. 3 shows an air conditioner 11 according to another embodiment of the present invention.
FIG. 3 is a block diagram showing the electrical configuration of this embodiment, and this embodiment is similar to the above-mentioned embodiment, and the corresponding portions bear the same reference numerals. It should be noted that in this embodiment, the thermistor 13 is provided to detect the outside temperature. Control circuit 15
Is the outside temperature detected by this thermistor 13,
According to the difference from the room temperature detected by the thermistor 3, the opening amount when the window 6 is opened as described above is adjusted and controlled. As a result, it is possible to prevent a sudden drop in room temperature and further improve habitability.

Although the opening and closing of the window 6 is realized by using the window opening and closing motor M4, the gear 8 and the rack rail 10 in the above-described embodiment, another configuration such as an air cylinder is provided as another embodiment of the present invention. May be used. Furthermore, when opening and closing the window 6, the crime prevention function may be enhanced by interlocking the locking or unlocking operation of the key 12.

[0016]

As described above, according to the present invention, the window is opened when the cooling operation is stopped. Therefore, even in a highly airtight room, it is possible to prevent a rapid temperature rise after the cooling operation is stopped. Therefore, the habitability can be improved.
