[Detailed Description of the Invention] This invention automatically adjusts the temperature setting level of electrical equipment equipped with temperature regulators such as air conditioners so that the amount of electricity consumed by electrical equipment used indoors falls within a preset amount of electricity. The present invention relates to a control device that performs control.

Among electrical devices that use indoor wiring, air conditioners such as air conditioners are used for long periods of time and consume a large amount of electricity.However, if the amount of current contracted with the power company is small, it is recommended to use the above air conditioners. Naturally, there is less room for other electrical equipment to be used, and the number of times the breaker installed based on the contracted current amount is tripped increases, causing the inconvenience of cutting off all electrical equipment in the house each time. Therefore, a device was needed to prevent this inconvenience from occurring.

Additionally, the demand for energy conservation has created a need for devices that reduce the amount of electricity consumed by air conditioners compared to their normal usage.

This invention was made to solve the above-mentioned need. A control unit is provided in the indoor wiring, and the control unit compares a preset value with the total electricity consumption of the operating equipment to determine the set value. When the temperature exceeds this level, the temperature in the room when the air conditioner is in use is compared with the set temperature of the temperature regulator of the air conditioner, and the set temperature level of the temperature regulator is moved in the direction that reduces the amount of electricity consumed. be.

The present invention will be explained below using illustrated embodiments.

In Figure 1, 1 is an integrated wattmeter, 2 is a breaker, 13 is indoor wiring, and 4 is air conditioning equipment L1 connected to this indoor wiring.
A control unit that controls the operating state of ~Ln, 5
is a current transformer that detects the current consumption of indoor wiring, and its output is input to the control unit.

R1 to Rn are switch box parts that receive control signals from the control unit 4 and control the temperature level of the temperature regulator to be moved according to the state of the air conditioner.

The switch boxes R1 to Rn respond one by one with different frequency signals, and each frequency signal becomes an address signal for each of the switch boxes R1 to Rn.

Next, the configuration of the control unit 4 will be explained with reference to FIG.

7 is a predetermined current setting device for setting a predetermined current value in advance;
is the current value from this predetermined current setting device 7 and the above indoor wiring 3
A level comparator that detects the current consumption of the current transformer 5 and generates an output when the current value from the current transformer 5 is larger; 8 is the output terminal of the level comparator 6; 9 is a step counter, and 10 is a clock pulse generator for the step counter 9, which starts oscillation at the output of the level comparator 6.

The step counter 9 is connected to the output terminal 8 of the level comparator 6.
and the clock pulse generator 10 as an input signal, and therefore, when there is an output from the level comparator 6, that is, when the detected current value is more than the predetermined current value, the clock pulse generator 10 clock Counting starts with a pulse, and the counting method is such that the contents of the step counter 9 advance from the initial [OO...0] by one each time a clock pulse is input [100...0], (010... O〕
.

The count advances as [001...0].

12 takes the output terminal 8 of the level comparator 6 as an input signal, and after the output signal of the level comparator 6 is generated, the air conditioner L1 to Ln
When the level of the current consumption detected by the current transformer 5 becomes smaller than the predetermined current value due to the decrease in the amount of electricity consumed, and the output of the level comparator 6 disappears, that is, the output of the level comparator 6 becomes 2.
This is a delay circuit such as a mono-multi-by-break circuit that operates when the value state changes from 1 to 0, and its output signal serves as the reset power for the step counter 9.

f1 to fn are oscillators that serve as address signals for switch boxes R1 to Rn that control the operating states of air conditioners L1 to Ln, with each oscillation output as one input, and the pulse output of the clock pulse generator 10 as the other. It is connected to the terminal game-1-A, ~A11, which serves as the terminal input.

B1 to Bn are AND gates, and step counter 9
With the individual output lines of A as inputs at one end, the AND gate A
, ~An are input to the other end.

Therefore, as an example, the step counter 9 is [100...
0] and there is a pulse output from the clock pulse generator 10, the frequency fl will be generated at the output of the AND gate B.

The frequency f2 is generated in the output of the AND gate B2 when the step counter 9 is [010...O] and there is a pulse output from the clock pulse generator 10.

Reference numeral 13 denotes an OR gate, which receives the outputs of the AND gates B1 to Bn, and its output is fed to the indoor wiring 3 via a coupling transformer 14.

To explain the operation of the control unit 4 having the above configuration, the current consumption flowing through the indoor wiring 3 is detected by the current transformer 5, and the predetermined current value is set by the current consumption value and the predetermined current value setting device 7. is compared with the current consumption value by the level comparator 6, and when the current consumption value is the same, an output signal is generated in the level comparator 6, the clock pulse generator 10 is started to operate with the output signal, and the clock pulse generator 10 is started with this pulse output. Switch box R1~
The frequencies of the oscillators f1 to fn, which are address signals for each of Rn, are set as fl in the first step, f2 in the second step, etc.
The step counter 9 is activated to generate signals in sequence as shown in .

On the other hand, on each device side, the switch boxes R1 to Rn that receive this address frequency signal operate to reduce the amount of electricity consumed by the air conditioners L1 to Ln connected to each switch box R1 to R. By continuing the counting operation of the step counter 9 until the current consumption of the indoor wiring 3 becomes equal to or less than a predetermined current value, it is intended to reduce the amount of electricity consumed by the air conditioner.

Next, the configuration of the switch boxes R1 to Rn that control the air conditioners L1 to Ln will be explained with reference to FIG.

15 is a coupling transformer that takes out the address frequency signal from the indoor wiring 3, 16 is a tuning circuit and switch box R1
It is tuned only to the address frequency f10).

17 is an amplifier for amplifying the tuning signal of the tuning circuit 16; 18;
is a relay operated by the output of the amplifier 17.

Reference numeral 19 denotes an opening/closing section of IJI/-18, which is inserted into the output of the temperature setting circuit section 20 of the temperature adjustment circuit of the air conditioner L1.

21 is a temperature detection element such as a thermistor that detects the indoor temperature, and 22 is a temperature sensor that uses the output of the temperature detection element 21 manually.
The electric conversion circuit 23 is a temperature comparator for cooling, and one input terminal inputs an electric signal of the room temperature, and the other input terminal inputs an electric signal from the temperature setting circuit section 20 of the temperature regulator of the air conditioner L1. /- is input via the opening/closing section 19, and a signal is output when the room temperature is higher than the temperature setting circuit section 20 of the humidity regulator.

24 is a temperature difference level comparator for cooling, 25 is a temperature difference level regulator for cooling, and the temperature difference level comparator 24 for cooling uses the output of the temperature difference level regulator 25 for cooling as one input, and performs a temperature comparison for cooling. When the temperature difference level of the cooling temperature difference level regulator 25 is higher than the output of the cooling temperature comparator 23, a signal is output.

26 is a temperature comparator for heating, and the connection of the input terminal to the comparator 23 for cooling is reversed, so that the output of the temperature setting circuit section 20 of the air conditioner is higher than the output of the temperature-electrical conversion circuit 22 for room temperature. Outputs a signal if it is a dog.

27 is a heating temperature difference level comparator, 28 is a heating temperature difference level regulator, and the heating temperature difference level comparator 27 uses the output of the heating temperature difference level regulator 28 as one input, and performs heating temperature comparison. The output of the device 26 is used as the other human power, and when the former is stronger than the latter, it outputs a signal.

29 and 30 are switches that operate in conjunction with the cooling/heating selector switch in the air conditioner L1, 31 is a control line that controls the temperature setting of the temperature adjustment setting circuit section 20 of the air conditioner to increase the set temperature, and 32 is a control line Similarly, this is a control line that controls to lower the set temperature. During cooling, the output terminal of the cooling temperature difference level comparator 24 and the set temperature increase control line 31 are connected via the changeover switch 29, and during heating, the heating temperature difference level comparator 24 is connected to the set temperature increase control line 31. The output end of the level comparator 27 and the set hot water temperature lowering control line 32 are connected via a changeover switch 30.

To explain the operation of the switch box R1 configured as above, when the current consumption of the indoor wiring exceeds a predetermined current value, the control unit 4 sequentially sends the switch box R1
-Rn address frequency signals f1 to fn are fed to indoor wiring, and in the switch box R1 described here, the address frequency signal f1 is selectively tuned by a tuning circuit 16 via a coupling transformer 15, and amplified by an amplifier 17. The width relay 18 is operated and the relay opening/closing part 19 is closed.

Here, a case where the air conditioner L1 is performing cooling operation will be described as an example.

The indoor temperature is A℃, the set temperature of the temperature setting circuit section 20 of the air conditioner is B'C1, and the temperature difference level regulator 25 for cooling is C'C.
Then, the output of the cooling temperature comparator 23 has A'C>B.
When 'C, output signals A'C to B'C are generated.

Furthermore, the output of the cooling temperature difference level comparator 24 is 0°C>
C°C-(AoC-B 'C) only when A°C-BoC
produces an output signal of

This output signal of 0°C-(AoC-B°C) is sent via the changeover switch 29 to the temperature setting increase control line 31 to change the set temperature of the temperature adjustment setting circuit section 20 of the air conditioner to this CoC-(
It operates to raise the output signal valve of A'C-B'C).

To give a concrete numerical example, if the indoor temperature is A°C -21°C, the set temperature of the air conditioner B'C is 20°C, and the temperature difference of the cooling temperature difference level regulator 25 is C°C -5°C, then CoC- (A
'C-B℃)=5℃-(21℃-20℃)-4℃, therefore, set the humidity of the temperature adjustment setting circuit section 20 of the air conditioner to 4℃.
℃ increase, i.e. B'C two 20℃ + 4℃ = 24℃
By controlling the air conditioner L1, the operation of the air conditioner L1 can be controlled, and as a result, the amount of electricity consumed by the air conditioner L1 can be reduced.

Similarly, in the case of heating operation, the heating temperature difference level regulator 2
If the temperature difference level of 8 is D'C, when B℃>A℃, an output signal of BoC-A℃ is generated at the output of the heating temperature comparator 26, and an output signal of BoC-A℃ is generated at the output of the heating temperature difference level comparator 27. is D
D'C-(B ℃-A only when ℃＞(B ℃-A℃)
'C) is generated, and this output signal is passed through the changeover switch 30 to the set temperature lowering control line 32 to generate the output signal D'.
In addition to the output signal of C-(B'C-A'C), it operates to lower the set temperature of the temperature adjustment setting circuit section 20, and as a result, the operation of the air conditioner L1 is controlled and the amount of electricity consumed is reduced. can be done.

Through the above operations, it is possible to sequentially control the operation of the air conditioners R1 to Rn until the current consumption falls within a predetermined current value.

In addition, in the explanation in the figure, when the current consumption exceeds a predetermined current value, the control unit 4 feeds the address frequency signal f1 to the indoor wiring as the first step, and switches the switch box R that receives this address frequency signal f1.
1 was explained as an example, but the AND gate array A in FIG.
It goes without saying that other address frequency signals f2 to fn can be fed to the indoor wiring as a first step by changing the connections between the outputs of 1 to An and the AND gate arrays B1 to Bn.

The same applies to the second and subsequent steps. Although different frequencies such as f, j, f2, etc. have been described as address frequency signals, it is needless to say that a code string of 2 brigadier generals may be used as an address.

Furthermore, although the case has been described in which indoor wiring is shared as a transmission line, it goes without saying that a dedicated line may be used as the transmission line.

Note that the switch box described above is connected to the power supply of the air conditioning equipment, and does not operate when the air conditioning equipment is not operating.

As described above, in order to keep the electricity consumption of air conditioning equipment that uses indoor wiring within a predetermined value, this invention monitors the electricity consumption in the control unit, and when it exceeds a predetermined value, it sends a control signal to the switch box on the air conditioning equipment side. Since the temperature level of the temperature regulator is controlled in a direction that reduces the amount of electricity consumed, it is extremely effective in terms of energy conservation.
