Abstract

PURPOSE:To change a room temperature and improve a comfortable feeling by a method wherein a movement of a person is detected, a changing-over from a normal operation mode to 'a good night' operation mode and its reverse changing-over operation are automatically performed and in case of 'a good night' operation mode, a movement of a sleeping person showing frequent turning-over movement is directly detected. CONSTITUTION:As a person moves into a detected region A within a room, an amount of incident infra-red rays to a sensor 3 is varied, and a variation signal is outputted from the sensor 3. This variation signal is counted for a predetermined period of time and an amount of movement of a person is taken. A reference value capable of acknowledging a time near a sleeping time is set and then this reference value is compared with the counted value. With this arrangement, the time near sleeping is detected and at this time a changing- over from a normal operation mode to 'a good night' operation mode and its reversing operation are automatically carried out. A room temperature at the 'good night' operation mode is varied and a feeling of comfortable state is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a control device for an air conditioner that has a sleep mode function in addition to a normal operation mode control function for controlling the room temperature to maintain it at a set temperature. It is something.

(Prior Art) As a conventional example of a control device for an air conditioner having a sleep mode function as described above, for example, Japanese Patent Laid-Open No. 62-3
The device described in Japanese Patent No. 2239 can be mentioned. The device requires the user to turn on the Good Night Moto Switch.
By operating N, the normal operation mode is switched to the sleep mode, and thereafter, control is performed to gradually shift the room temperature from the set temperature every predetermined time period. This saves labor and improves comfort while sleeping.

(Problems to be Solved by the Invention) However, in the conventional device described above, in order to switch to the sleep mode, the user must operate the sleep mode switch every time, and each time the user wakes up,
Since it is necessary to operate a switch to cancel the sleep mode, there is a problem of poor operability.

Furthermore, in conventional devices, the amount of shift in the room temperature from the set temperature in the sleep mode is uniquely done according to a program set in the device in advance, so the amount of shift in the room temperature from the set temperature in the sleep mode is uniquely done according to the program set in the device in advance. There is also the problem that depending on how many shifts you make, you may feel uncomfortable, such as feeling too hot, and you may not necessarily be able to maintain sufficient comfort.

This invention has been made in view of the above, and its purpose is to provide a control device for an air conditioner that can improve the operability associated with switching to the sleep mode, and to provide a comfortable air conditioner during the sleep mode. An object of the present invention is to provide a control device for an air conditioner that can further improve performance.

(Means for Solving the Problems) Therefore, as shown in FIG. 1, the control device for an air conditioner according to the first aspect of the present invention provides an air conditioner that, in the normal operation mode, blows air in order to bring the indoor temperature close to the set temperature. A control device for an air conditioner, comprising an operation control means 31 that controls the operation of the conditioner, and also controls the operation in a sleep mode to bring the indoor temperature closer to a temperature deviated from the set temperature. , a sensor 3 that is sensitive to infrared rays emitted from a human body and outputs a change signal when the amount of infrared rays emitted from the human body changes, and a light condensing means 5 that makes light within a detection area S in the room enter the sensor 3. and a first counting means 41 that counts the change signal output from the sensor 3 for a predetermined time; It has a switching means 42 for switching from the normal operation mode to the sleep mode.

Further, in the control device for an air conditioner according to the second claim, in the device according to the first claim, when the count value in the first counting means 41 exceeds a second reference value, the control device for an air conditioner changes from the sleep operation mode to the normal operation mode. Switching to the driving mode is indicated by - in the switching means 42.
will do.

Further, as shown in FIG. 2, the air conditioner control device according to the third aspect controls the operation of the air conditioner to bring the indoor temperature close to the set temperature in the normal operation mode, while in the sleep operation mode. is an air conditioner control device comprising an operation control means 3I for controlling the operation so as to bring the indoor temperature close to a predetermined deviation temperature from the set temperature, and the control device is equipped with an operation control means 3I for controlling the operation so as to bring the indoor temperature close to a predetermined deviation temperature from the set temperature. A sensor 3 that senses the light and outputs a change signal when the incident amount changes, and a sensor 3 that detects light within a detection area S in the room.
a second counting means 43 for counting the change signal output from the F2 sensor 3 for a predetermined period of time;
A changing means 44 is further provided for changing the amount of deviation of the indoor temperature from the set temperature in the sleep mode based on the count value of the second counting means 43.

In this specification, the word "light" refers to electromagnetic waves with wavelengths in the range of approximately 1 nm to 1 mm, including visible light, ultraviolet rays, and infrared rays, and preferably wavelengths of 6 to 1 mm.
It shall mean infrared rays of around 15 μm.

(Function) In the control device for an air conditioner according to the first aspect, when a person exists in the detection area S indoor and the person moves, the amount of infrared rays incident on the sensor 3 changes. give birth to
Therefore, at this time, the sensor 3 outputs a change signal. In addition, since the output frequency of this change signal depends on the speed and frequency of the person's movement, that is, the amount of activity, by counting the above change signal for a predetermined period of time,
It is possible to understand a person's activity level. Since the amount of activity after going to bed is significantly lower than before going to bed, - in the above device, a first reference value that can distinguish before and after going to bed is set, and this first reference value and the above count value are set. By comparing the values, it is detected that it is time to go to sleep, and at this time the normal operation mode is automatically switched to the sleep mode.

Therefore, since there is no need for a switching operation by the user, operability is improved.

Further, in the air conditioner control device according to the second aspect, the count value of the change signal from the sensor 3 is compared with a second reference value that can identify the difference in the amount of activity before and after waking up. The system detects when you wake up, and automatically switches from normal operation mode to sleep mode at this time. Therefore, even when the user wakes up, there is no need for the user to operate the switch to return to the normal operation mode, which further improves operability.

Further, in the air conditioner control device according to the third aspect, the change signal from the sensor 3 corresponding to the movement of the person similar to that described above is counted, and the change signal from the sensor 3 corresponding to the movement of the person is counted, and the control device calculates the change signal from the sensor 3 corresponding to the movement of the person. For example, by determining from the above count value that movements such as turning over in bed become more frequent, the indoor temperature in the sleep mode is further changed. In this way, since the sleeping state is directly detected and the room temperature is changed according to the sleeping state, comfort can be improved more than before.

(Example) Next, a specific example of the control device for an air conditioner according to the present invention will be described in detail with reference to the drawings.

First, an air conditioner configured to apply the present invention will be described with reference to the refrigerant circuit diagram shown in FIG. In the figure, 11 is a compressor, and a discharge pipe 12 of this compressor 11 and a suction pipe 14 in which an accumulator 13 is installed are respectively connected to a four-way switching valve 15. An outdoor heat exchanger 16, a pressure reducing mechanism 17 consisting of a capillary duplex, and an indoor heat exchanger 18 are connected in this order to constitute a refrigerant circulation circuit.

In the air conditioner having the above configuration, the refrigerant discharged from the compressor 8!11 is transferred to the outdoor heat exchanger 1, as shown by the solid line arrow in the figure.
6 to the indoor heat exchanger 18, and the outdoor heat exchanger 1
6 as a condenser and the indoor heat exchanger 18 as an evaporator, cooling operation is performed, and the four-way selector valve 15 is switched from above to discharge refrigerant from the compressed all, as shown by the broken line arrow in the figure. is circulated from the indoor heat exchanger 18 to the outdoor heat exchanger 16, and the indoor heat exchanger 18 is converted into a condenser,
Heating operation is performed by making each outdoor heat exchanger 16 function as an evaporator.

The indoor heat exchanger 18 is installed inside an indoor unit 20 of the wall-mounted type shown in FIG. And this room [20
A human detection device 4 having a built-in sensor 3 that is sensitive to infrared rays emitted from a human body and corresponding to body temperature is disposed on the side of the suction port 21 on the front panel of the device. Further, a light condensing plate (light condensing means) 5 made of a Fresnel lens is attached to the front panel side surface of the human detection device 4, and this condensing plate 5
Through the sensor 3, light from a detection beam set for the room, which will be described later, is focused on the sensor 3.

As shown in FIG. 5, the sensor 3 is composed of a dual type pyroelectric infrared sensor having a pair of light receiving windows 3a and 3b in its light receiving section. Next, the principle of human detection operation will be explained. For the sensor 3, as shown in FIG.
a-1b, ■a-11b, and l1la-111b are set for the detection area, and the light from the left detection zones Ia, Ha, and T[la is set in multiple pairs for the left side of the sensor 3. The light from the window 3a and the right detection zones rb, nb, and mb of the multiple pairs are set so as to enter the right light receiving window 3b of the sensor 3, respectively. The sensor 3 detects a person every time there is a change in the amount of infrared rays incident on only one of the light receiving windows 3a, 3b, which corresponds to body temperature, that is, every time a person enters or leaves one of the detection zones. It is designed to output a signal. Note that when the incident amount of infrared rays changes simultaneously in both the light receiving windows 3a and 3b, that is, when the light from both of the pair of detection zones changes in the same way, the sensor 3 , 3b is electrically processed so that each detection signal from each detection element cancels each other out, and in this case, no change signal is output, which prevents sunlight, etc. This is designed to prevent malfunctions caused by external light or vibrations.

The light condensing plate 5 has the function of setting the detection zone for the detected head area, but the person detection device 4 is installed inside an indoor unit installed on the wall of an 8-tatami room, for example. 4, the two-part light condensing plate 5 is, as shown in FIG.
It is composed of a Fresnel lens with a total of six small lens sections, two rows up and down and three rows left and right. As shown in the figure, the detection area S on the floor of the 8 tatami room, excluding the area directly below the indoor unit 20, is divided into two in the front and back direction from the installation wall surface of the room [20] and three in the left and right direction. A detection line extending to each of the unit areas A to F of a total of six areas is formed by each of the above-mentioned small lens sections.More specifically, as shown in FIGS. Two pairs of detection zones (■, ■) formed by the unit area A are located across the unit area A, and two pairs of detection zones (■, ■) formed by the small lens part at the center of the lower stage cross the unit area B. The two pairs of detection zones ■ and ■ by the small lens part are the unit area C
Furthermore, each pair of detection zones (1), (2), and (2) formed by the small lens portions on the upper stage side are positioned so as to cross the unit areas D, E, and F, respectively.

As mentioned above, by forming the detection zones ■ to ■ evenly throughout the indoor detection area S,
When a person moves in the room, the person moves in and out of the non-concentration zone A change signal is output as a detection signal.Then, as the speed and frequency of a person's movement, that is, the amount of activity, increases, the frequency of entering and exiting the detection zones ① to ① increases, so that changes from the sensor 3 are detected. The frequency of signal output also increases.

FIG. 9 shows a control block diagram of the air conditioner. As shown in the figure, the operation control device 30 is provided with an air conditioning operation control section (operation control means) 31, a target temperature generation section 33 to which a storage section 32 is connected, and an operation mode determination section 34. The air conditioning operation control section 31 includes an operation switch 36 and a cooling/heating changeover switch 37 in an operation remote control 35, and a room temperature sensor 3 consisting of a thermister or the like.
8 is connected to the target temperature generator 33, and the switching position signal from the cooling/heating changeover switch 37 and the set temperature set by the room temperature setting switch 39 are inputted to the target temperature generating section 33. First, to explain the control operation in the normal operation mode, when the operation switch 36 is turned on, the air conditioning operation control section 31 controls the four-way switching valve I according to the switching position of the cooling/heating switching switch 37.
5 and the compressor 11 is activated, and the above-mentioned cooling operation or heating operation is started. In this normal operation mode, the temperature set by the room temperature setting switch 39 is output as a target temperature from the target temperature generation section 33 to the air conditioning operation control section 31, and the room temperature detected by the room temperature sensor 38 is compared with the target temperature. By automatically starting and stopping the compressor 11 according to the results, the room temperature is controlled to be maintained at the target temperature, that is, the set temperature.

Next, I will explain the control using the sleep mode.
First, the control flowchart in FIG. 10 will be explained with respect to the control in the driving mode determining section 34 having the function of switching between the normal driving mode and the sleep driving mode based on the output signal from the sensor 3. I will explain it with reference to.

When the air conditioning operation control unit 31 starts operating in the normal operation mode, the process shown in FIG. 10 is started, and first, step S
], the operation mode discrimination bit M is set to "0", which corresponds to the normal operation mode. Also, step S2
In step S3, the activity counter Nc is initially set to zero, and then in step S3, the monitoring time timer tc is started. The processes of steps 84 to S6 are repeated until the time measured by the timer tc reaches, for example, 60 minutes, as shown in step S7. Step S4 is a step of monitoring the output from the sensor 3, and as described above, the output from the sensor 3 is monitored in any one of the detection zones Every time a change signal corresponding to the coming and going of a person is output from the sensor 3, the process switches to steps S4 to 35, and in step S5 the activity counter Nc is
A process of adding 1 to , that is, a process of counting the number of occurrences of the change signal is performed. In this way, the number of occurrences of the change signal counted by the activity number counter Nc is:
As mentioned above, the value corresponds to the amount of human activity indoors. In step S6, the amount of activity after going to bed is ゛ζ compared to before going to bed.
In this step, the first reference value N1, which is determined and set as a lower limit value for the movement of a person before going to bed, is compared with the count value of the activity counter Nc. If Nc exceeds N1 and it is therefore determined that the time is before bedtime before the monitoring time of 60 minutes has elapsed, the counting process is interrupted and the process moves from step S6 to S8. After confirming that the operation mode discrimination pin l-M is 0 corresponding to the normal operation mode in step S8, the process returns to step S2, and after initializing Nc to O again, in step S3, the timer t
Reset c and restart it, and from this time again 6

and the number of activities counter N during the 60 minute monitoring period.
If the counted value at step c does not reach the above N1, the process moves to steps S7 to 39 in the second part of J, and after confirming that the operation at this point is the normal operation mode, the number of activities counter is counted in step S10. The count value at Nc is compared with a second reference value N2. This second reference value N2 is set by determining the upper limit for the movement of a person after sleeping.
2. This value is sufficiently smaller than the first reference value N1. Therefore, if the above-mentioned Nc is smaller than this N2, then in step Sll it is determined that this Nc is not zero] After that, in step 512, a switching signal to the sleep operation mode is output to the target temperature generation section 33, This causes a switch to the sleep mode. Then, in step 513, the driving mode discrimination pin l-M is set to "1" corresponding to the sleep driving mode, and the process returns to step S2, so that the monitoring process during the sleep driving is thereafter performed.

In the monitoring process during sleep driving, the process from step S2 to step S7 calculates the change signal from the sensor 3 every 60 minutes by using the activity counter N.
Perform with c. In this process, when the count value of the activity mass number counter Nc exceeds the first reference value Nl, the process moves from step S6 to 38, and furthermore, in this step S8, the driving mode discrimination pin 1-M is set to 1. Therefore, the process of step S14 is then executed, and in this step, a switching signal to the normal operation mode is output.

In other words, the count value of the activity number counter Nc is the first reference value N
When the number exceeds 1, it means that the person's movements after waking up have been detected, so the sleep mode returns to the normal mode. After outputting this switching signal, the process returns from step 514 to step Sl, and therefore, the process in the normal operation mode described above is repeated again. Furthermore, in the monitoring process during slumber driving, the count value of the activity number counter Nc is the first reference value N.
If 60 minutes have passed without reaching 1, the process moves from step S7 to step S9, and then returns to step S2 depending on the determination result of M in this step, so that the process returns to step S2 above. The process of counting the change signal from the sensor 3 every 60 minutes from 1 to step S7 is repeated.

On the other hand, during monitoring in the normal operation mode, if the count value of the activity counter Nc is a value between the first reference value N1 and the second reference value N2, the process returns from step S10 to step S2. processing is performed and operation continues in normal operating mode. Furthermore, in step Sll, it is determined whether or not the counted value of the activity number counter Nc is zero.
If no change signal corresponding to the movement of a person is output from the sensor 3 during the monitoring period of 0 minutes, it is assumed that there is no person in the room, and in this case, the absent operation mode is activated in step S]5. Outputs a switching signal to As a result, the target temperature generation unit 33 generates a temperature that is increased by, for example, 1°C from the set temperature during cooling, and by, for example, 1°C during heating.
The temperature reduced by °C is set as the target temperature and output to the air conditioning operation control section 31. In this way, you can shift the set temperature.
In addition to conserving energy, the amount of shift is suppressed to a certain extent to reduce discomfort when people return to the room. After performing the process in step S15, the change signal from the sensor 3 is monitored in step S16, and when the change signal is output, that is, it is determined that a person has returned to the room, step S17
After outputting the cancellation signal for the absent operation mode and returning to the normal operation mode, the process returns to step S2.

In response to each operation mode switching signal from the operation mode determination section 34 as described above, the target temperature generation section 33 sets the set temperature in the normal operation mode, and sets the temperature shifted by, for example, a degree C from the set temperature in the absent operation mode. is output to the air conditioning operation control section 31 as the target temperature. On the other hand, when the operation mode determining section 34 generates a switching signal to the sleep mode, the target temperature generating section 33 starts the process shown in FIG. 11, and in the process of this process, the target temperature is temporarily changed. The setting of the target temperature during the sleep operation will be described below with reference to FIG. 11 for the case during the heating operation for convenience.

First, in step 521, the target temperature Ts is set to the set temperature T.
set and outputs it to the air conditioning operation control section 31.

Therefore, the nap operation starts with an operation that maintains the indoor temperature at the set temperature Tset. Next, in step S22, after initially setting the counting pin l-i to 1, step S22 is performed.
At step 23, a holding time timer t (i), in this case since i is 1, a timer L(1) is started. A plurality of holding time timers t (i) are provided, and as will be described later, a timer corresponding to the value of 1 is selected and sequentially performs a time counting operation. Step S24 is a step for initializing the activity counter Ns to zero, and after starting the monitoring time timer ts in step S25, the output state from the sensor 3 is monitored in step S26, and the above-mentioned holding time is set in step S27. The process continues until the timer t (i) reaches its set time, or until the monitoring time timer ts reaches its set time in step S28. During this period, each time a change signal is output from the sensor 3 corresponding to the movement of a person in the room, 1 is added to the activity counter Ns in step S29, and the number of occurrences of the change signal is calculated by the activity counter Ns. I'll keep counting.

The monitoring time timer ts is set to a shorter time, for example, about 10 minutes, than the holding time timer t(i), which is set to a time of 30 minutes to 1 hour, for example, and therefore the sensor' While the output state monitoring process in step 3 continues, the monitoring time timer Ls reaches its set time, and at this time, the monitoring process in step 1- is interrupted and the process returns to step 32.
The process moves from B to S30. Step S30 is a step of comparing the counted value of the activity number counter Ns with the third reference value N3, and if Ns exceeds N3, the target temperature Ts at that point is determined in step S31.
After the temperature obtained by subtracting the corrected shift temperature ΔS from ΔS is output to the air conditioning operation control unit 31 as a new target temperature Ts, the process returns to step S24. Then, after initializing Ns to 0 again,
The monitoring time timer ts is reset and restarted (step 525), and the process of counting the change signal from the sensor 3 is repeated.

The above-mentioned third reference value N3 is set as a value that can be used to detect movements such as turning over frequently when the room temperature is too high and it becomes uncomfortable to sleep. At each short set time interval at ts, if the Ns value during that time exceeds N3, a process is performed to appropriately lower the room temperature.

On the other hand, in step S27, the holding time timer L (
When it is determined that 1) has reached the set time, the process proceeds to step S32, and the shift temperature Δ5(1) stored in the storage unit 32, in this case, since i is 1, ΔS (1) is performed one after another, and the set temperature Tse
The temperature obtained by subtracting the above △5 (1) from t is the new target temperature T.
It is output to the air conditioning operation control section 31 as s. As a result, the operation is changed to maintain the indoor temperature at a temperature lower than the set temperature by △5(1).

After making this change, 1 is added to the variable bit 1 in step S33, and then the process returns to step S23, where the holding time timer starts step 2) and the above process is repeated.

-1- The setting time in (1) for the name retention time timer is timer tO), for example, about 30 minutes, and the time is set to gradually become longer as 1 becomes larger. Furthermore, the shift temperature Δ5(i) for each time amplifier in each timer t (i) is set to a gradually larger value as i becomes larger. As a result, after starting sleep operation, timer t(1), L(2), L(3)...
As each set time elapses, Δ5 is sequentially increased from the set temperature.
(1), Δ5(2), Δ5(3), . . . stepwise room temperature control is performed. This is intended to improve energy-saving driving and sleeping comfort, but with only such predetermined change patterns,
For example, depending on the difference in the number of futons, etc., it may not always be possible to obtain sufficient comfort, so based on the detection results of the human movement by the sensor 3 described above, the room temperature is also changed based on the movement. . As a result, air conditioning operation control that can further improve comfort is performed.

Although FIG. 11 shows an example of control during heating operation, during cooling operation, the process in step S32 is performed by adding the shift temperature Δ5(j) to the set temperature Tset to obtain a new target temperature Ts. This is done by controlling the room temperature to gradually rise from the set temperature.

Although specific embodiments of this invention have been described above, the two-part embodiments do not limit this invention, and various changes can be made within the scope of this invention. For example, In the above embodiment, step 33 shown in FIG.

Further, steps S25 and S26 in FIG.

Furthermore, in the above configuration, the light from a plurality of detection zones ■ to ■ which are discretely formed in the room is incident on one sensor 3, but for example, the movement of a person in the room can be detected by multiple sensors. It is also possible to configure it so that. It is also possible to configure the sensor "3" with a sensor other than a pyroelectric infrared sensor, such as a thermoelectric sensor.

(Effects of the Invention) As shown in Part 2, the air conditioner control device according to the first claim of the present invention detects the movement of a person after going to bed, which is significantly lower than before going to bed. By this,
Switching from the normal driving mode to the sleep driving mode is automatically performed, and therefore no switching operation by the user is required, which improves operability.

Further, in the control device for an air conditioner according to the second aspect, the switching from the sleep mode to the normal mode is automatically performed by detecting the movement of the person, which changes significantly before and after waking up. Therefore, even when the user wakes up, there is no need for the user to operate the switch to return to the normal operation mode, which further improves operability.

In addition, in the air conditioner control device according to the third aspect, during the sleep mode, the movement of a sleeper who frequently turns over, for example due to excessive heat, is directly detected, and the movement of the sleeper increases. Since the room temperature is further changed in accordance with the detection results, comfort can be improved more than before.
