Description

[Detailed description of the invention] This invention allows the air conditioner to be operated by hand using wireless signals transmitted from a transmitter. This invention relates to an improvement to an air conditioner that can control the temperature of the room by detecting the temperature of the room around the machine, converting it into a wireless signal, and transmitting it.

As shown in the figure, this type of air conditioner has a transmitter 1 that converts various operations into wireless signals and transmits them, and an air conditioner that has the function of receiving signals from this transmitter 1 and controlling various operations. The transmitter 1 includes a built-in temperature sensing element 7 such as a thermistor for each operation switch and a bonnet 8 for setting the room temperature.

Next, details of the temperature control function within the transmitter will be explained with reference to the block diagram of FIG.

3 is a battery for the power source for the transmitter 1.

Reference numeral 4 denotes a timer circuit, which is configured to close its contact 5 periodically, for example, every 3 minutes for 1 second.

9 is a temperature detection circuit consisting of a thermistor 7, etc.; 6 is a room temperature output from the temperature detection circuit 9; and a volume 8 for setting the room temperature.
This is a comparison circuit that compares the set temperature with the set temperature set in .

10 is a signal transmitting circuit indicating that the room temperature is higher than the set temperature, 11 is a signal transmitting circuit indicating that the room temperature is below the set temperature, and the comparison circuit 6 selects either the transmitting circuit 10 or 11. and is transmitted from the transmitting element 12 only while the contact 5 is closed.

The situation is shown in FIG. 3, where one of the signals is transmitted every 3 minutes for 1 second.

In addition, the configuration of the receiver side (air conditioner main body) is as shown in the block diagram of FIG. 4, as shown in the block diagram of FIG. 14 and is identified by various signals.

The switch 15 is activated by the temperature control output from the reception and discrimination circuit 14.
The operation of the compressor 20 is controlled by driving and opening/closing the contacts 16 thereof.

In the air conditioner configured in this manner, the following problems occur from the viewpoint of usability.

That is, when the set temperature is changed by operating the temperature setting volume, the user must wait up to three minutes until the next temperature control signal arrives before the user can see the result.

In other words, if the air conditioner is too cold, even if you raise the set temperature, the compressor will stop operating until the next temperature control signal is sent, which can take up to three minutes.

This invention is intended to eliminate the following disadvantages with a simple structure, and one embodiment thereof will be described.

In FIG. 2, 13 is a switch provided in parallel with the contact 5 of the timer circuit 4, and is configured so that the user can close the contact at any time.

Then, by pressing the switch 13, the timer circuit 4
Temperature control signals can be sent to the air conditioner main body at any time, regardless of the timing of transmission.

Therefore, according to this invention, if the compressor operation is to be stopped due to excessive cold, a control signal can be immediately transmitted, making it possible to provide coordinated and comfortable cooling.
