Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner with a remote temperature control device.

Conventionally, remote temperature control devices for these air conditioners incorporate a temperature sensing element such as a thermistor inside with a transmitter, and the receiver on the air conditioner's main body controls whether the compressor on the main body is turned on or off.
It only sent a signal indicating what to do.

In this case, it was impossible to maintain a comfortable air temperature unless the compressor ON-OFF signal was sent from the transmitter all the time or quite frequently.

Furthermore, it has been impossible to confirm whether the signals transmitted constantly, periodically, or intermittently from the transmitter are being reliably received.

This invention aims to eliminate the above-mentioned drawbacks, and includes a capacitive switch (hereinafter referred to as an "electrostatic switch") that senses the touch of a human hand inside a transmitter, a temperature setting value selection switch (hereinafter referred to as a "temperature control switch"), etc. ), and only when a person's equal capacitance body contacts the temperature control switch, the electrostatic switch sends the transmitter's transmission, and the receiving side receives the previously received temperature setting value. Only when the temperature set value received this time is different, the reception is notified by a display such as sound or light.

The present invention will be described in detail below with reference to the practical examples shown in Figs. The transmitter 1 is composed of a slide contactor 6 that is selectively supported in contact with the sliding shaft 5 between the temperature patterns 4, and a knob 7 for manually operating the slide contactor 6 to set a temperature set value. Built-in.

Reference numeral 8 denotes an electrostatic switch, and a contact 9 of a capacitive body such as a person is installed and wired on the side of the knob 7 of the slide contact 6 of the temperature control switch 2 so as to operate in conjunction with the temperature control switch 2. A transmitting antenna 11 is connected to a transmitting circuit 10 that outputs a transmitting signal that is switched by an adjustment switch 2.

12 is a main body of the air conditioner, and 13 is a receiving antenna built into the main body 12, which receives the signal transmitted from the transmitter 1.

14 is a received signal decoding digital converter;
This is to decode the signal received by 3.

Reference numeral 15 denotes a first memory, which temporarily stores the signal decoded by the received signal decoding digital converter 14, that is, the temperature setting digital value, and connects the temperature setting digital value received before this reception with the first memory 15. This is to transfer the data to the second memory 16 that is currently in use.

1γ is a first comparator, one of which is connected to the first memory 15 and second memory 16 to compare the contents of the first memory 15 and second memory 16, and the other is connected to a buzzer 18 that generates a sound, etc. Connect and output, only when the comparison results are different”
Outputting H'' signal.

19 is a temperature sensing element such as a thermistor, and 20 is an analog-to-digital converter, which converts the resistance change of the temperature sensing element 19 into a digital quantity.

21 is a second comparator, which connects the first memory 15 and the analog-to-digital converter 20, compares the temperature setting digital value of the first memory 15 and the analog-digital amount, and depending on the result, selects "L" or The "H" level is output to the other connected relay 22.

A relay contact 23 is opened and closed by the output of the second comparator 21, and is connected to the compressor 24 to perform ON-OFF control.

The operation of the air conditioner control device configured as described above will be specifically explained.

First, in the transmitter 1, the finger 25 operating the temperature control switch 2 touches the contact 9 of the knob 7, and the electrostatic switch 8 is closed.

Next, when the knob 7 is moved sideways and the temperature control switch 2 is switched to set the desired temperature, the temperature control signal after switching passes through the antenna 11 of the transmitting circuit 10 and is transmitted to the receiving antenna 1.
Received on 3rd.

The received signal is decoded and digitally converted by the analog-to-digital converter 14, temporarily stored in the first memory 15, and the previously stored temperature control signal is transferred to the second memory 16.

At this time, the first comparator 17 compares the contents of the first memory 15 and the second memory 16, and if they are different, a buzzer 18 is output.
Outputs the H" signal and generates sound, etc.

This allows the transmitter operator to know that the control device on the main body 1 has indeed received the signal when the temperature control switch 2 is switched.

In this case, it is clear that the buzzer 18 on the main body 1 emits a sound not only when the operator touches the knob 7 of the transmitter 1 but also when the temperature control switch 2 is switched.

A similar effect can also be achieved using a microcomputer based on a sequence stored program system.

That is, as shown in FIG. 3, an amplifier 14 for amplifying a received signal and a converter 20 for converting the resistance value of a sensing element 19 such as a thermistor into a digital value are input inside the air conditioner main body 12. There is a one-chip microcomputer (hereinafter referred to as microcomputer) 26. The output of the microcomputer 26 is connected to a buzzer 18 and an output device 22, and the output device 22 opens and closes contacts 23 to operate a compressor 24.

The operation using the microcomputer 26 in this case will be explained using the flowchart in FIG. 4. At the beginning of the overall program, when the received signal detection and decoding program 27 and the decoding completion determination program 28 decode the signal and the result is YES, the routine Coming out of 29.

The information that has passed through the routine 29 is continuously sent to the memory of a read/write storage device (not shown) provided in the microcomputer 26, and is compared with previously stored temperature setting information that is also held in the memory. The routine 33 is skipped when the judgment is different according to the routine 33 consisting of a program 31 to perform the process and a judgment program 32 thereof.

At this time, the contents of the memory are outputted to a buzzer or the like through a program 34 that continuously transmits them.

Further, after the program 35 is finished, a sequence instruction memory in the microcomputer 26 is written so as to continue to a compressor output control program 36 for the comparator.

As described above, in this invention, the contactor of the electrostatic switch is integrally provided with the temperature control switch of the transmitter and is interlocked with the contactor, and the set temperature and the previously set temperature memory are provided so that the temperature can be compared with each other. Since the compressor is controlled ON-OFF by comparing the set temperature and the detected temperature, a confirmation sound is emitted from the main unit only when the temperature control switch is switched, ensuring that the transmission from the transmitter is confirmed. The present invention has many advantages, such as being able to reduce the power consumption of the transmitter as much as possible.
