Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioning display device, and in particular to an air conditioning display device used in an air conditioner equipped with an adjustment device that can operate and set air conditioning physical quantities such as occupancy and humidity in multiple stages within a predetermined range. It is related to.

Generally, in an air conditioner, when trying to control the room temperature in an air-conditioned room to a desired room temperature using a temperature control device, for example, the temperature control device compares the set temperature set by the temperature adjustment device and the room temperature, and there is a difference. At times, the operation of the compressor motor is controlled to perform cooling or heating operation to keep the room temperature close to the set temperature.

The temperature adjustment device used is one that can be set in multiple stages within a predetermined temperature range.

Such temperature settings are normally selected so that the resident beach can obtain a comfortable room temperature throughout the cooling or heating season and can make detailed settings.
It is possible to operate in 1°C increments within the range of 30°C to 30°C.

However, the temperature control device requires a trial run for cooling when the room temperature is outside the specified humidity range, that is, when the room temperature is below 19°C, and a test run for heating when the room temperature is above 31°C. Therefore, it is possible to operate the test run position beyond the predetermined temperature range.

In this case, if the occupant mistakenly puts the device into the test run position during normal operation, the room temperature will not only not be kept within a comfortable temperature range, but also there is a risk of harm to health.

Furthermore, this problem also applies when a humidity control device is used to dehumidify or humidify an air-conditioned room.

The present invention has been made in view of the above-mentioned principles, and includes an adjusting means that can perform setting operations for air conditioning physical quantities such as temperature and humidity in multiple stages within a predetermined range, and an air conditioner that can be operated by setting the adjusting means. A start/stop operation means for stopping the operation, a setting display means for lighting up and displaying a set position in conjunction with the setting operation of the adjustment means, and an alarm display that lights up intermittently when the adjustment means is operated outside a predetermined range. By configuring an air conditioning display device with means, if the adjustment device is accidentally operated in an area that is harmful to health, a lamp will be lit intermittently so that this can be determined, and in history, for trial operation. Continuous operation means for continuously operating the air conditioner when the adjustment means is operated outside a predetermined range, and alarm display means for intermittently lighting and displaying in conjunction with the operation of the adjustment means outside the predetermined range. The air conditioner display device is configured to clearly indicate that it is in a trial run state.

An embodiment of the present invention will be described below when applied to a temperature control device for an air conditioner. In FIG. 1, 1 is a temperature sensor that measures the room temperature of an air-conditioned room (not shown) as an analog voltage; 2 is an amplifier that amplifies the sensor output, 3 is an A-D converter that converts the amplifier output into a digital quantity, and 4 is a BC! converter output. A BOD converter 5 converts into a D (binary coded decimal) code; 5 is a resistor 6 and 7f2 connected in series between a bus l1 to which a DC power supply (not shown) is supplied and the ground, and resistors 8 and 9; The partial voltage between each series resistor is calculated by the human power port of the microcomputer 10■,■
This temperature adjustment device is composed of a high temperature side operation switch 11 and a low temperature side operation switch 12.

The microcomputer 10 is composed of one chip or several chips of LSI (Large Scale Integrated Circuit), reads the output from the BCD converter 4 through the human power port 0, and reads the output from the BCD converter 4 through the human power port 0 and the settings specified by the temperature adjustment device 5. value (temperature), and if there is a difference, close the output switch 13, supply AC power 14 to the compressor motor ('C!M), perform cooling operation or heating operation, and set the room temperature. The function that maintains the temperature near the temperature has been cured.

15 are output ports of the microcomputer 10 ■, ■,
■、■ 4-digit binary signal [0, 0, 0, 1] to [1, 0, ■, 1] to [1] to CDI 16 evolution 10
A 4-16 decoder converts into a base number, 16 is an amplifier that amplifies each output of the 4-16 decoder 15, and 13 NPN transistors Tr1 to Tr13 are used as shown in FIG.
It consists of

DA1 to DA13 are light emitting diodes whose cathodes are connected to the collectors of each transistor, and the diodes D
A1 is for low temperature side alarm display, diode DA13 is for high temperature side alarm display, diodes DA2 to DA 1 2 are 11
They are used to display the set temperature of each stage.

The anode of each diode is connected to the collector of a PNP transistor 1γ whose emitter is connected to a bus line l2 to which DC power is supplied.

DB1 to DB13 are light emitting diodes whose cathodes are connected to the collectors of the transistors of the amplifier 16, and whose anodes are connected to the collector of the PNP l-transistor 18 whose emitter is connected to the bus line l2. used for purposes.

The base of each transistor 17 and 18 is connected to the expander 1.
9.20 are connected to the output ports (2) and (2) of the microcomputer 10, respectively.

FIG. 3 shows the control box 21 of the air conditioner, in which each operation switch 11, 12 of the temperature adjustment device 5 and the rod-shaped 2
A column temperature setting display section 22 and a room temperature display section 23 are arranged.

The temperature setting display section 22 has 13 lamps LAI to LA1.
3, each of the light emitting diodes DA1 to DA in FIG.
1 3 lights up in conjunction with the light emission.

The room temperature display section 23 has 13 lamps LB1 to LB1.
3, each of the light emitting diodes DB1 to DB in FIG.
It lights up in conjunction with the sound of 13.

Lamps LAI and LA 1 3 and LB? and LB13 are arranged at both ends of each display section with a slight distance between them.

When the operation switches 11 and 12 of the temperature adjustment device 5 are not operated, there is no signal from the input ports ■ and ■, so the microcomputer 10 outputs the pre-stored reference values [0, 1].
, 1, 1] are supplied to the 4-16 decoder 15 from output ports 0, ①, ②, ②.

As a result, the decoder 15 produces an output at the ■ terminal, and the amplifier 1
The base voltage is supplied to the transistor Tr7 of No. 6.

At this time, if the output of the output port [Yes] and ■ is set to [1, 0], the transistor 1γ is turned on by the output of the inverter 19 and 20, and the transistor 18 is cut off.
The light emitting diode DAT is made conductive through the transistors 17 and Tr7 to emit light, and the lamp LA7 at the center of the temperature setting display section 22 lights up as shown in FIG.

This corresponds to a set temperature of 25°C.

Next, when the room temperature detected by the temperature sensor 1 is 31°C or higher, the microcomputer 10 reads this as [1, ■, 0, ■] based on the human power from the human power port, This is supplied to the 4-16 coder 15 from output ports ■, ■, ■, ■.

At this time, the outputs of the output ports ■ and ■ should become [0, ■].

Therefore, the transistor 17 is cut off, the transistor 18 is conductive, and based on the output from the 0 terminal of the 4-16 decoder 15, the transistor Tr13 of the amplifier 16 has a base power, so the diode DB13 is connected to the transistor 1.
8, conduction is established via Trl3, and the lamp LB13 at the right end of the room temperature display section 23 lights up, indicating that the room temperature is 31° C. or higher.

In this way, the set temperature signal and room temperature signal are alternately supplied from the output ports ■, ■, ■, ■, and synchronized with these signals.
By alternately supplying the signals 1, 0], [0, ■] from the output ports ■ and ■ and repeating this in short cycles, the lamps LAγ and LB13 are lit almost continuously to the naked eye. It looks like it is.

Then, in the air conditioner, the microcomputer 10 detects the difference between the set temperature and the room temperature and the output switch 13 closes, so that the compressor motor (CM) rotates and performs cooling operation.

When the room temperature gradually decreases and reaches 30°C, the lamp LB13 turns off and the lamp LB12 turns on, and the room temperature display section 2
3, the lamp on the left lights up every time the room temperature drops by 1 degree Celsius.

When the room temperature drops to 25℃, the microcomputer 10
reads this as [0, ■, 1, ■] and reads the lamp LB.
7 is turned on, and when it is detected that there is no difference from the setting A, the output switch 13 is opened and the cooling operation is stopped.

When the room temperature rises by 1° C., the lamp LB8 is turned on and the cooling operation is restarted, and this is repeated thereafter, so that the room temperature is maintained near the set temperature (25° C.).

The case where the room temperature is lower than the set temperature (25° C.) and the heating operation is performed is the same as described above.

In other words, when the room temperature is below 19℃, the output ports ■, ■,
The signals from ■ and ■ become [0, 0, 0, ■], and the leftmost lamp LBI of the room temperature display section 23 lights up.

Then, when the room temperature reaches 20°C due to heating operation, the L lamp will turn on.
B2 lights up, and thereafter the lighting of the lamp shifts to the right every time the temperature rises by 1°C.

When the temperature of the room vortex reaches 25°C, the lamp LB of the room temperature display section 23 turns on.
7 and the lamp LAγ of the temperature setting display section 22 light up to notify that the room vortex has reached the set temperature, and the output switch 13 is opened to stop the heating operation.

When it is desired to change the set anchorage, each operation switch 11, 12 of the temperature adjustment device 5 is operated.

That is, to increase the set temperature, the high temperature side operation switch 11 is closed.

The microcomputer 10 increases the set temperature by 1° C. every time the switch 11 closes for 0.5 seconds.

For example, to increase the set temperature by 3℃ from 25℃, switch 1
1 should be closed for 1.5 seconds.

As a result, the set temperature signals of the output ports ■, ■, ■, ■・ change from [0, ■, 1, ■] to [1, 0, ■, 0] in order, so 4-16 The output of the decoder 15 changes in the order of ■, ■, ■, ■, and the temperature setting display section 22
The lighting shifts from the lamp LAγ to the lamp LA10 via the lamps LA8 and LA9.

Further, to lower the set temperature, the low temperature side operation switch 12 is closed.

In this case as well, the set temperature is lowered by 1° C. every time the closing time elapses between 0 and 5 seconds.

Therefore, in order to lower the set temperature from 28°C to 22°C, it is sufficient to close the switch 12 for 3 seconds.

As a result, the signal of the microcomputer 10 becomes [1, 0
, ■, 0] to [0, ■, 0, 0], and the temperature setting display section 22 turns on sequentially from the lamp LA10 to the lamp LA4.

In this way, the set temperature can be varied in 11 steps from 20° C. to 30° C., and can be displayed on the lamps LA2 to LA12 of the display section 22.

Lamps LAI and LA 1 at both ends of the temperature setting display section 22
3, the set temperature signal of the microcomputer 10 is [
0, 0, 0, 1], [1, ■, 0, ■], 4-1
It lights up when the output is supplied from the terminals (1) and (4) of the 6 decoder 15, and is turned on by adjusting the operation switches 11 and 12.

That is, if the operation switch 11 is kept pressed, the lamp LA 1 3 will finally turn on, and the microcomputer 1 will turn on.
The 0 signal is fixed at [1, ■, 0, 1].

Conversely, if the operation switch 12 is held down, the lamp LA1 lights up and the signal is fixed at [0, 0, 0, 1].

In this device, when the cooling command is issued, the temperature adjustment device 5 is operated to
0, 0, 0, ■], the microcomputer 10 causes the compressor motor (CM) to operate continuously regardless of the room temperature, so that a trial run of the air conditioner can be performed even when the room temperature is below 20°C. .

By storing the program shown in the flowchart in FIG. 4 in the microcomputer 10, the output ports 0, 5 from the output ports
Planking is performed every second so that the [1, 0] signal is not output (however, the [0, 1] signal is output), and the lamp LA1 is intermittently lit to notify that the test run is in progress.

Therefore, even if the test run position is mistakenly operated during normal cooling operation, the lamp LAI will be lit intermittently, so this can be easily determined and the room will not be excessively cooled.

Also, by creating a similar program when a heating command is issued,
By lighting the lamps LA 1 3 intermittently, the test run position can be displayed and the room can be prevented from being accidentally heated and dried.

In the above embodiment, only one lamp of each display section 22, 23 was turned on to display the set temperature and room temperature, but if the display circuit shown in FIG. Each temperature can be displayed by the number of lights lit, and many other variations are possible.

Additionally, the present invention is not limited to display devices used in vorticity control devices, but is suitable for various display devices for air conditioners, such as display devices for humidity control devices.

As described above, the present invention provides an air conditioner equipped with an adjustment device that can set and operate air conditioning physical quantities such as temperature and humidity in multiple stages within a predetermined range, with a lighting display indicating the setting position in conjunction with the operation of the adjustment device. The display device consists of a setting display lamp that indicates when the adjustment device is operated beyond a predetermined range, and an alarm display lamp that lights up intermittently to indicate when the adjustment device is operated beyond a predetermined range. When the air conditioner is operated continuously, the lamp lights up intermittently so that this can be identified, and even when the air conditioner is operated at a test run position that exceeds the predetermined range of the adjustment device, it is also operated at this position. This is a useful device that provides an air conditioning display device that is easy to use and can be expected to provide comfortable air conditioning.
