Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner with a remote control device.

[0002]

2. Description of the Related Art Conventionally, an air conditioner that can be remotely operated by using a remote control device has been widely used without directly touching an operation unit provided on the front surface of the air conditioner. These remotely operated air conditioners and the like have a receiving unit for infrared rays and the like, and are controlled to reliably receive electromagnetic waves such as infrared rays transmitted from the transmitting unit of the remote control device and perform a designated operation. When the receiving section of the air conditioner receives a signal from the remote control device, the sounding section such as a buzzer responds to the transmitting side of the reception. However,
Since the volume of the buzzer and the like cannot be switched between daytime and nighttime, there is a problem that the buzzer sound at night is too loud and causes noise and annoyance.

[0003]

DISCLOSURE OF THE INVENTION The present invention solves the noise problem of the buzzer sound of the conventional air conditioner described above, and the volume of the sounding part of the buzzer or the like from the air conditioner at the time of remote control operation is adjusted between daytime and night. It is to provide something that can be switched.

[0004]

In order to solve the above-mentioned problems, the present invention provides a control unit for receiving a signal from a remote controller,
A sounding unit that notifies the reception, a drive resistance that limits the drive current of this sounding unit, a switching unit that switches this drive resistance, a memory that stores preset time zone data, and a count of the time of day. A timer for performing, a comparing unit for comparing the time information of the timer with the reception time received by the input unit, and a CPU for controlling the input unit, the switching unit, the memory, the timer, and the comparing unit are provided. The drive resistance of the switching unit is switched according to the result of the comparison of the switching unit.

[0005]

Since the air conditioner according to the present invention is configured as described above, when a signal is input from the remote controller,
The CPU inputs the time information of the timer, compares the input time information with the time zone data stored in the memory, and if the result of the comparison corresponds to the night time zone, the switching unit drives the drive resistor. , Which reduces the drive current for driving the sounding body, thereby reducing the volume emitted from the sounding body. If the input time information corresponds to a daytime time zone, the switching unit may be switched to a daytime drive resistor to increase the drive current flowing to the sounding body and increase the volume. Can be done.

Embodiments of the air conditioner according to the present invention will be described in detail below with reference to the drawings. In the embodiment shown in FIG. 1, 1 is a control and switching block, and 2 is an announcing unit that sounds a buzzer or the like. A remote controller 3 sends a signal to the control and switching block. Reference numeral 4 is a first resistor that limits a drive current for driving the buzzer, and 5 is a second resistor having a resistance value different from that of the first resistor. 6 is a buzzer, and 7 is an input unit for inputting a signal from a remote controller. The CPU 8 inputs the time information of the timer. A switching unit 9 switches the volume of the buzzer between day and night. Reference numeral 10 is a memory for storing time zone data to be set, and 11 is a timer for counting the time of day and managing the time. Reference numeral 12 is a comparison unit for comparing the time data input from the remote controller with the time zone data stored in advance in the memory.

In the above structure, when a signal from the remote controller is input to the input unit 7, the CPU 8 inputs the current time from the timer, and the input time data and the time zone data stored in the memory 10 in advance. In comparison, if the current time belongs to the night time zone, the switching unit 9 switches the drive resistance to the resistance 4 side, thereby reducing the volume of the buzzer 6. If the input time information belongs to the daytime zone, the drive resistance is switched to the daytime resistance 5 side, thereby increasing the volume of the buzzer.

In the embodiment of FIG. 2, reference numeral 21 is a control and switching block, and 22 is an announcing section for sounding a buzzer or the like.
A remote controller 23 sends a signal to the control and switching block. Reference numeral 24 is a first resistor that limits a drive current for driving the buzzer, and 25 is a second resistor having a resistance value different from that of the first resistor. Reference numeral 26 is a buzzer, and 27 is an input unit for inputting a signal from a remote controller. The CPU 28 inputs the time information of the timer. A switching unit 29 switches the volume of the buzzer between day and night. Reference numeral 30 is a memory for storing time zone data to be set, and 31 is a comparison unit for comparing time data input from the remote controller with time zone data stored in advance in the memory. With the above configuration, the memory 30 stores time zone setting data that divides the time zone of the day into daytime and nighttime in advance.
Remember. When sending a control signal from the remote controller 23,
The transmitted time data is superimposed on the signal, the transmitted time data is compared with the time zone setting data stored in the memory by the comparison unit 31, and the switching unit 29 is used by the switching unit 29 according to the comparison result. , 25, and when the transmitted time belongs to the time zone of night, the buzzer 26 is driven by the resistance on the night side, and the volume of the buzzer is made smaller than that in the daytime. If the transmitted time belongs to the daytime zone, the drive resistance is switched to the daytime side, thereby increasing the volume of the buzzer.

[0009]

As described above, according to the air conditioner of the present invention, the volume from the air conditioner can be switched between the daytime and the nighttime when the remote control is operated. It is possible to make an air conditioner with low noise without causing annoying noise and noise.
