TECHNICAL FIELD The present invention relates to an air conditioner.

[Conventional technology]

Fig. 37 is an electric circuit diagram of a conventional air conditioner shown in Japanese Patent Application No. 01-56956 (hereinafter referred to as "first conventional example"), and Fig. 38 controls the operation of this conventional example. It is a flowchart.

In FIG. 37, 1 is a power switch, 2 is a thermistor or a similar temperature detector for detecting the room temperature, 3 is an A / D converter, 4 is a switch part for operating modes, and 5 is a It is a microcomputer as a cooling / heating capacity calculating means having a cooling / heating capacity setting / changing means, and has an input circuit 7, a CPU 8, a memory 9, and an output circuit 10. A switch unit 4 for setting a set temperature, an operation mode, etc., and a room temperature detected by the temperature detector 2 are input to the input circuit 7 via the A / D converter 3. The heating / cooling capacity varying device 11 changes the rotation speed of the compressor 6 by the output from the output circuit 10 to control the cooling / heating capacity.

Next, the operation of the first conventional example will be described with respect to the cooling operation.
This will be described with reference to FIG. FIG. 38 is a flow chart including the cooling / heating capacity calculation means described in the microcomputer 5. First, when the power switch 1 is turned on, this flowchart starts. Set temperature Ts in step F101
Is set. Steps F102 and F103 are the initial settings for the change mode, and in step F102 the integrated time t
Reset, and the high cooling capacity is set in step F103.
In step F104, the room temperature Tr detected by the temperature detector 2 is input, and in step F105, in the normal mode, step
At F106, the cooling capacity is calculated from the set temperature Ts and the room temperature Tr, and the operation is performed. Even if the operation mode is the change mode in step F105, the room temperature is higher than the set temperature in step F107.
If it is 1 [deg] or more higher than Th, the same operation as the normal mode is performed in step F106. This is because if the temperature is extremely higher than the set temperature, the comfort zone may not be entered. The operation mode is the change mode, and the room temperature is Th + 1 [deg].
When the temperature becomes lower, the change mode is set, and the process proceeds to step F108. In step F108, the cooling capacity is determined, and if the set cooling capacity is a high cooling capacity that is an increase of, for example, 20% of the current cooling / heating capacity, in step F109, the cooling capacity is decreased of, for example, 20% of the current cooling / heating capacity. If the cooling capacity is low, the process proceeds to step F115. In the initial stage of the change mode, the high cooling capacity is initially set in step F103, so the process proceeds to step F109. If the operating time is integrated in step F109, the room temperature Tr is higher than the low temperature set value Tl in step F110, and the operating time t is less than the constant time to in step F111, the process proceeds to step F112 to perform high cooling capacity operation, Return to step F104 to step F1 from step F104
Go to 09. The low temperature set value Tl is a temperature lower than the set temperature. Therefore, when the room temperature Tr is higher than the low temperature set value Tl and the operation time t is within a fixed time, the high cooling capacity operation is continued. When the room temperature Tr becomes equal to or lower than the low temperature set value Tl, in step F110, if the operating time t becomes longer than the certain time to, the process branches to step F111, the low cooling capacity is set in step F113, and the total is calculated in step F114. The operating time t is reset and the process returns to step F104. In this case, since the operation mode is the change mode and the room temperature is lower than Th + 1, the process proceeds to step F108, and since the low cooling capacity is set, the process proceeds to step F115. When the operating time t is integrated in step F115, the room temperature Tr is lower than the high temperature set value Th in step F116, and the operating time t is smaller than the certain time to in step F117, the process proceeds to step F118 to perform the low cooling capacity operation. , And returns to step F104. Therefore, the room temperature Tr repeatedly rises and falls between the high temperature set value Tr and the low temperature set value Tl in the vicinity of the set temperature within the constant time to.

First, the air conditioner of the second conventional example shown in the electric circuit diagram of FIG. 39 and the exploded perspective view of the wind direction deflecting device of FIG. 40 will be described.

This air conditioner attempts to vary the cooling / heating capacity by changing the rotation speed of the compressor, and controls the cooling / heating capacity so that the room temperature reaches the set temperature, so that the room temperature can be controlled to be equal to the set temperature. In FIG. 39, 1 is a power switch, 2 is a thermistor or a similar temperature detector for detecting a room temperature, 3 is an A / D converter, 4 is a switch unit for setting a set temperature, etc. Reference numeral 5 is a microcomputer equipped with a cooling / heating capacity calculating means for calculating the cooling / heating capacity according to the room temperature detected by the temperature detector 2, and has an input circuit 8, a CPU 9, a memory 10, and an output circuit 11. . The output of the switch unit 4 and the output from the temperature detector 2 are input to the input circuit 8 via the A / D converter 3. The cooling / heating capacity variable device 12 controls the rotation speed of the compressor 7 by the output from the output circuit 11. In addition, the drive circuit 17
Is rotated by the output from the output circuit 11 to rotate the right motor 19b connected to the right louver 19a, deflect the blown airflow to the center and to the right, and rotate the left motor 20b connected to the left louver 20a. The blowout airflow is deflected in the center and leftward directions, and the center motor 21b connected to the center louver 21a is rotated to control the blowout airflow to be deflected upward or horizontally and downward. Figure 40 shows the relationship between these louvers and the motor.

Next, the operation of the air conditioner of the second conventional example will be described.
The case of the cooling operation will be described with reference to the flowchart in the figure. The operation starts when the power switch 1 (Fig. 39) is turned on. At step F1, the room temperature t detected by the temperature detector 2 is input. Next, at step F2, room temperature t ≧ first
It is determined whether or not the temperature is the predetermined temperature t1, and if room temperature ≧ first predetermined temperature, the compressor 7 is controlled by the cooling / heating capacity varying device 12 in step F3.
While rotating at high speed, the right motor 19
b stops in the right rotation, left motor 20b stops in the left rotation, central motor 21b stops in the left rotation, the direction of the blown airflow is downward and concentrated to the center, room temperature t ≧ first predetermined temperature t1
If not, it is determined in step F4 whether the first predetermined temperature t1 ≧ room temperature t ≧ second predetermined temperature t2, and the first predetermined temperature t1 ≧ room temperature t ≧
If it is the second predetermined temperature t2, the compressor 7 is rotated at a middle speed by the cooling and heating capacity varying device 12 at the step F5, and the right motor 19b is stopped by the drive circuit 17 in the left rotation and the left motor 20b.
Stops by rotating right, the central motor 21b stops by rotating left,
The direction of the blown airflow is changed to the downward direction and the direction branched to the left and right, and if it is not the first predetermined temperature t1 ≧ room temperature t ≧ second predetermined temperature t2, it is determined in step F6 whether the second predetermined temperature t2 ≧ room temperature t. , T2 ≧ t, in step F7, the cooling / heating capacity variable device
The compressor 7 is rotated at a low speed by 12 and the drive circuit 17
Causes the right motor 19b to stop in the left rotation, the left motor 20b to stop in the right rotation, the central motor 21b to stop in the right rotation, and changes the direction of the blown airflow to the upward or horizontal direction branched to the left or right. Controlled as.

In this way, when the room temperature is approaching the predetermined temperature, the rotation speed of the compressor 7 is gradually reduced, and the room temperature control is performed so that the room temperature becomes equal to the predetermined temperature as shown in the control characteristic diagram of FIG. 42. At the same time as the room temperature is high and the cooling air rises, the blowout airflow is directed downward and centrally and directly to the user.As the room temperature rises, the blowout airflow is controlled not to blow directly to the user. .

Therefore, when the air conditioner is operated, in order to control the room temperature, the rotation speed of the compressor is controlled as the room temperature changes to bring the temperature closer to the set temperature. In consideration of this, the blowing airflow is blown toward the user, but since this blowing direction control is performed only at room temperature and a specified temperature, it blows toward the residential area regardless of the blowing temperature and blowing time. There is a problem that the person is uncomfortable due to the influence of the cold air flow for a long time.

Next, regarding the third conventional example, FIG. 43, FIG. 44 and FIG.

Next, regarding the operation of the third conventional example, regarding the cooling operation,
This will be described with reference to FIGS. 44 and 45. FIG. 44 is a flow chart including the heating / cooling capacity calculation means stored in the microcomputer 5 (FIG. 43). First, when the power switch 1 is turned on, the flowchart shown in FIG. 44 starts. In step F201, the set temperature Ts is set. The room temperature Ta detected by the temperature detector 2 is input in step F202, the temperature difference ΔT between the set temperature and the room temperature is calculated in step F203, the room temperature is higher than the set temperature in step F204, and the set temperature and room temperature in step F205. Temperature difference ΔT is, for example, 1 deg
If so, the cooling / heating capacity is calculated in step F211, and the compressor 7 is operated by the cooling / heating capacity varying device 12 in step F212. If the room temperature is lower than the set temperature in step F204, the process proceeds to step F210 to turn off the compressor 7 and stop the cooling operation. In step F205, the temperature difference between the set temperature and room temperature Δ
When the absolute value of T is, for example, 1 deg or less, the change mode is entered.
In step F206, the current cooling and heating capacity is used as the reference capacity, and cooling operation is performed with the capacity increased by, for example, 10%.
F207 for a certain period of time. After a certain period of time, step F2
In 08, the cooling and heating capacity is reduced by 10% from the reference capacity, for example, and the cooling operation is performed. If the absolute value of the difference between the room temperature and the set temperature is larger than 1 deg in step F205 and the room temperature is not near the set temperature, step F2
The flow branches to 11, the cooling / heating capacity is calculated, and the compressor 7 is operated by the cooling / heating capacity varying device 12 in step F212. As a result, the change mode is set only when the room temperature is near the set temperature, and the room temperature is controlled so as to change near the set temperature.

 FIG. 45 is a control characteristic diagram when the cooling operation is performed.

The horizontal axis represents time, and the vertical axis represents temperature and cooling capacity. When the operation of the air conditioner is started at time T1, the room temperature decreases toward the set temperature indicated by the broken line. Determine the cooling capacity from the difference between the set temperature and room temperature. The cooling capacity decreases as the room temperature decreases, and at time T2, the difference between the room temperature and the set temperature becomes small, and when it stabilizes with the cooling capacity, the mode changes at time T3.

Then, the cooling / heating capacity starting / stopping device 6 operates the compressor 7. If the room temperature is lower than the set temperature in step F104, the compressor 7 is turned off by the cooling / heating capacity start / stop device 6 in step F106. In this way, the cooling operation is performed so that the room temperature is maintained near the set temperature. FIG. 48 shows the control characteristic section. The temperature is too low when the air conditioner is turned off because the temperature detector has a time delay, there is an on / off control range, and once it is turned off, it cannot be restarted for a certain period of time. Feels cold, and when turned on again, the room temperature rises too much, and there is a problem that the user feels heat in the portion b in the figure.

Next, the operation of the air conditioner will be described with reference to the flowchart of FIG. 50 in the case of the cooling operation. The operation is started when the power switch 1 is turned on.
The set temperature is set in step F201, and the room temperature detected by the temperature detector 2 is input in step F202. Next, in step F203, a temperature difference ΔT is calculated from the set temperature and the room temperature, and in step F204, when the room temperature is approaching the set temperature, the cooling capacity is gradually reduced so that the room temperature is above a certain range centered on the set temperature. The cooling capacity is calculated so that when it becomes higher, the cooling capacity is increased. According to the calculated cooling capacity, in step F205, the cooling / heating capacity varying device 12

In Fig. 1b, 1 is a power switch, 2 is a thermistor or a similar device for detecting a room temperature, 3 is an A / D converter, 4 is a switch part for operating modes, etc., Reference numeral 5 denotes a microcomputer (hereinafter referred to as a microcomputer) as a cooling / heating capacity calculating means B having a cooling / heating capacity setting / changing means, and has an input circuit 8, a CPU 9, a memory 10 and an output circuit 11. The switch unit 4 for setting the set temperature, the operation mode, etc., and the room temperature detected by the first temperature detector 2 are input to the input circuit 8 via the A / D converter 3. The cooling and heating capacity variable device 12 is an output circuit 11
The rotation speed of the compressor 7 is changed by the output from the air conditioner to control the cooling / heating capacity. The above is the same as the above-mentioned conventional example. The vertical deflection louver operation calculating means for controlling the blown airflow, which is a feature of the first embodiment, will be mainly described below. Reference numeral 13 is a second temperature detector provided in an indoor heat exchanger (not shown) of the air conditioner, 14 is an A / D converter, and 15 is an upper / lower direction that changes the blowing direction of the blowing airflow by the output of the output circuit 11. This is a drive circuit for controlling a motor 16 which is a drive means C for reciprocating drive such as a servomotor to which a deflection louver 17 is attached. D is an up-and-down deflection louver operation computing means for varying the downward blowing time of the blown air flow according to the temperature of the indoor heat exchanger by the input from the second temperature detecting means, and is composed of the microcomputer 5.

Next, the operation of the first embodiment will be described with reference to FIGS. 3 and 4 by taking the cooling / heating operation as an example. FIG. 3 and FIG.
The figure is a flow chart including the cooling / heating capacity calculation means stored in the microcomputer 5. In FIG. 3, the difference from the flow chart (FIG. 38) of the conventional example is that it is provided between step F003 and step F004. Step Fsb1 that is a subroutine that is created, and the step that is a subroutine that is provided between Steps F007 and F008
It is Fsbd. Step FSb1 is an initial setting routine of step Fsb2, which sets the setting flag (= 1) and resets the integrated time of the lower blow-up and the upper blow-up, and has no relation to the operation. The cooling capacity control accompanying the room temperature control excluding step Fsb2 is the same as the above-mentioned conventional example, and performs the same operation. That is, when the power switch 1 is turned on, this flowchart starts, and as a result, the room temperature Tr rises between the high temperature set value Th and the low temperature set value Tl near the set temperature within a certain time period to,
Repeat the descent. The main feature of the present invention is step Fsb2, and FIG. 4 is a flowchart of this subroutine.

This subroutine will be described below with reference to FIG. 4 centering on the vertical deflection louver operation calculating means D. When branching to this subroutine, the setting flag is checked in step Fs01 in FIG. 4 and the flag is set. That is, when the setting is necessary, the process branches to step Fs02, and when the flag is not set, that is, when the setting is unnecessary, the process branches to step Fs06. Since the setting flag is set in the initial setting subroutine of this subroutine, the process first proceeds to step Fs02. The temperature of the indoor heat exchanger of the air conditioner in step Fs02
tf is measured, and in step Fs03, the downward blowout time shown in FIG. 6 is calculated. FIG. 6 is a characteristic diagram of the temperature of the indoor heat exchanger and the lower outlet time. As shown in the figure, when the temperature tf of the indoor heat exchanger is high, the lower outlet time is long and the temperature tf of the indoor heat exchanger is When the temperature is low, the downward blowout time is short, and therefore the downward blowout time corresponding to the temperature tf of the indoor heat exchanger at that time is calculated. Further, the upper blow-out time is calculated from the calculated lower blow-out time with a fixed cycle. In the case of the figure, the case of a cycle of 110 seconds is shown. Microcomputer 5 in step Fs04
The output of the output circuit 11 (Fig. 1b), the drive circuit 15, the motor 1
6 operates, the vertical deflection louver 17 rotates, and the blowing airflow is set to the downward blowing. In step Fs05, the setting flag is reset and the process returns to the main routine (FIG. 3). If the setting flag is not set (= 0) in step Fs01 in FIG. 4, the process proceeds to step Fs06, and if the blowing direction at that time is downward blowing, the downward blowing time is integrated in step Fs07. Then, in step Fs08, the set (step
Fs03) The bottom blowing time is compared with the cumulative time of the bottom blowing performed in step Fs07, and if not finished, the process returns to the main routine. If it is determined in step Fsg08 that the processing has ended, the process proceeds to step Fs09, and the output circuit 11 of the microcomputer 5
The drive circuit 15 and the motor 16 are operated by the output of, the vertical deflection louver 17 is rotated, and the blowing airflow is set to the upper blowing. In step Fs10, the lower blowout integrated time is reset, and the process returns to the main routine. If the blowing direction is upward, step Fs06
At step Fs11, the upper blowing time is integrated in the same manner as in the case of lower blowing, and at step Fs12, step Fs
In 03, the upper outlet time calculated from the temperature tf of the indoor heat exchanger is compared with the integrated time, and if not finished, the process returns to the main routine. In the case of the end, the setting flag is set to the setting side in step Fs13 (= 1), the upper blowout integrated time is reset in step Fs14, and the process returns to the main routine. In this way, in this subroutine, the cycle is made constant, and the operation of the lower blow-out and the operation of the upper blow-out according to the temperature of the indoor heat exchanger at that time are repeated.

FIG. 8 is a control characteristic diagram when the cooling operation is performed based on the first embodiment. The horizontal axis represents time, and the vertical axis represents the cooling capacity, room temperature, temperature of the indoor heat exchanger, and down-blowing time. When the operation mode is set to the normal mode and the operation of the air conditioner is started at time T1, the room temperature decreases toward the set temperature indicated by the broken line. Since the cooling capacity is determined from the difference between the set temperature and the room temperature, the cooling capacity decreases as the room temperature decreases, and
In addition, the difference between the room temperature and the set temperature is small, and the room temperature becomes stable along with the cooling capacity. When the change mode is set at time T3, the cooling capacity changes cyclically as shown in the figure, so the temperature of the indoor heat exchanger changes as shown in the figure due to the effects of the room temperature and the cooling capacity. As a result, the room temperature changes periodically near the set temperature. On the other hand, when the change mode is set at time T3, the lower outlet time changes as shown in the figure due to the changing temperature of the indoor heat exchanger. When the lower blowing time changes, the air flow that hits the user changes, which can be considered to change the stimulus amount of the user. It is considered that this stimulus is determined by the time the airflow hits the user and the temperature of the airflow. The longer the airflow hits the user, the greater the amount of irritation,
Also, the lower the temperature of the air flow, the greater the amount of stimulation. Sixth
The relationship between the blowout time and the temperature of the indoor heat exchanger shown in the figure is intended to equalize the amount of stimulation by this air flow. Also, the temperature of the indoor heat exchanger changes depending on the cooling capacity, and the lower outlet time changes depending on the temperature of this indoor heat exchanger,
Looking at this changing air flow from the user, this air flow change is random, and is close to the change of the natural wind. The natural breeze is said to be comfortable. Stimulation due to changes in room temperature and changes in the airflow comfortably stimulate the user's skin temperature receptors, activate physiological functions and the cerebrum, and are more comfortable and comfortable than the normal mode in which the room temperature is controlled at a constant level. It creates a good healthy environment.

Next, a second embodiment of the present invention will be described with reference to FIGS. 1b to 3, 5, 5, 7 and 9.

FIGS. 1b to 3 are the same as those of the first embodiment, and therefore these are adopted. As mentioned above, FIG.
Flowchart of the subroutine of step Fs02 in the figure, FIG. 7 is a characteristic diagram of the temperature of the indoor heat exchanger and the upper blowing time, 9th
The figure is a control characteristic diagram.

In FIG. 1b of the drawing, D2 is a vertical deflection louver operation calculating means, and the input from the second temperature detector 13 makes the downward blowing time of the blown air flow by the operation of the vertical deflection louver 17 constant, and The microcomputer 5 is a means for varying the time for which the blowing air is blown up according to the temperature. Since other configurations are the same as those in the first embodiment,
The duplicate description will be omitted.

Next, the operation of the second embodiment will be described with reference to FIGS. 3 and 5 by taking the cooling operation as an example.

3 and 5 are flowcharts including the cooling / heating capacity calculating means stored in the microcomputer 5. In FIG. 3, a conventional flowchart (FIG. 38) is shown.
The difference from step F003 and step F007 is a subroutine provided between step F003 and step F004.
And step Fs which is a subroutine provided between F008 and
b2. Step Fsb1 is the initial setting routine of step Fsb2, and sets the lower outlet time and the setting flag (=
1) The accumulated time of the lower blow-up and the upper blow-up is reset, and it has no relation to the operation. The cooling capacity control accompanying the room temperature control excluding step Fsb2 is the same as the above-mentioned conventional example, and performs the same operation. That is, when the power switch 1 is turned on, this flowchart starts, and as a result, the room temperature Tr repeatedly rises and falls between the high temperature set value Th and the low temperature set value Tl in the vicinity of the set temperature within a constant time to. The main feature of the second embodiment is step Fsb1, and FIG. 5 is a flowchart of this subroutine.

This subroutine will be described below with reference to FIG. 5 centering on the vertical deflection louver operation computing means D2. When branching to this subroutine, the setting flag is checked in step Fs01, and the flag is set. That is, when the setting is necessary, the process branches to step Fs02, and when the flag is not set, that is, when the setting is unnecessary, the process branches to step Fs06. Since the setting flag is set in the initial setting subroutine of this subroutine, the process first proceeds to step Fs02. Step Fs02
At, the temperature tf of the indoor heat exchanger of the air conditioner is measured, and at step Fs03, the upper outlet time shown in FIG. 7 is calculated. FIG. 7 is a characteristic diagram of the temperature of the indoor heat exchanger and the upper blowing time. As shown in the figure, when the temperature tf of the indoor heat exchanger is high, the upper blowing time is short and the temperature tf of the indoor heat exchanger is When the temperature is low, there is a long relationship with the upper blowing time, and the upper blowing time is calculated according to the temperature tf of the indoor heat exchanger at that time. In step Fs04 of FIG. 5, the drive circuit 15 and the motor 16 are operated by the output of the output circuit 11 of the microcomputer 5, and the vertical deflection louver 1
7 rotates, and the blowing airflow is set to the downward blowing. In step Fs05, the setting flag is reset and the process returns to the main routine. If the setting flag is not set (= 0) in step Fs01, the process proceeds to step Fs06, and if the blowing direction at that time is downward blowing, the downward blowing time is integrated in step Fs07. This lower blowing time is the initial setting subroutine,
It is preset to about 5 to 20 seconds. Step Fs
In 08, the set lower blow-out time is compared with the integrated time of the lower blow-out time performed in step Fs07, and if not finished, the process returns to the main routine. If it is determined in step Fs08 that the operation is finished, the process proceeds to step Fs09, in which the output of the output circuit 11 of the microcomputer 5 causes the drive circuit 15 and the motor 16 to operate, the up-and-down deflection louver 17 to rotate, and the blowing airflow to blow upward. Is set. In step Fs10, the lower blowout integrated time is reset, and the process returns to the main routine. If the blowing direction is upward blowing, the process branches to step Fs11 in step Fs06, and the upward blowing time is integrated as in the case of downward blowing.
Then, in step Fs03, the upper blowing time calculated from the temperature tf of the indoor heat exchanger is compared with the integrated time, and if not finished, the process returns to the main routine. In the case of the end, the setting flag is set to the setting side (= 1) in step Fs13, the upward blowing accumulated time is reset in step Fs14, and the process returns to the main routine.
In this way, in this subroutine, the operation of the upper blow-out and the preset operation of the lower blow-out according to the temperature of the indoor heat exchanger at that time are repeated.

FIG. 9 is a control characteristic diagram when the cooling operation is performed based on the second embodiment. The horizontal axis represents time, and the vertical axis represents the cooling capacity, the temperature of the indoor heat exchanger, and the upper blowing time. When the operation mode is set to the normal mode and the operation of the air conditioner is started at time T1, the room temperature decreases toward the set temperature indicated by the broken line. Since the cooling capacity is determined from the difference between the set temperature and room temperature,
The cooling capacity decreases as the room temperature decreases, and at time T2, the difference between the room temperature and the set temperature becomes small, and the cooling capacity stabilizes together with the cooling capacity. When the change mode is set at time T3, the cooling capacity changes cyclically as shown in the figure, so that the temperature of the indoor heat exchanger is affected by the room temperature and the cooling capacity and changes as shown in the figure.
As a result, the room temperature changes periodically near the set temperature.
On the other hand, when the change mode is set at time T3, the upper outlet time changes as illustrated due to the changing temperature of the indoor heat exchanger.
When the upper blowing time changes, the airflow that hits the user changes,
This can be considered that the amount of stimulation of the user is changing. It is considered that this stimulus is determined by the time the airflow hits the user and the temperature of the airflow. The longer the airflow hits the user, the greater the amount of irritation, and
The lower the temperature of the air flow, the greater the amount of stimulation. The relationship between the upper blowing time and the temperature of the indoor heat exchanger shown in FIG. 7 is intended to equalize the stimulation amount by the air flow. The change in room temperature and the change in air flow comfortably stimulate the user's skin temperature receptors, activating physiological functions and the cerebrum,
It provides a comfortable, comfortable and healthy environment compared to the normal mode in which the room temperature is constantly controlled.

In the first and second embodiments, the case where the selection switch for the normal mode and the change mode is provided has been described, but the change mode may be always entered without the selection switch.

Further, in the first and second embodiments, the case where the change mode is entered when the room temperature is in the range near the set temperature has been described, but the change mode may be entered at all times.

In the above, both the first and second embodiments have been described for cooling, but the same is true for heating, and the same effect can be obtained in all air conditioners whose cooling / heating capacity can be varied.

Next, a third embodiment of the present invention will be described with reference to FIGS. 1c and 10 to 17. FIG. 1c is an electric circuit diagram of a third embodiment of the air conditioner according to the present invention, FIG. 10 is a flow chart (1) for controlling the operation of the third embodiment, and FIG. 11 is the latter stage of the third embodiment. Flow chart (2) for controlling the operation, FIG. 12 is an operation explanatory view showing the relationship between the blowout temperature and the maximum downward blowing time, FIG. 13 is an operation characteristic diagram of the first stage of the third embodiment, FIGS. The figure which shows the experimental result of 3rd Example, FIG. 16 is a figure which shows the relationship between downward blowing time and a feeling of comfort, and FIG. 17 is a figure which shows room temperature and a feeling of temperature.

In FIG. 1c, 1 is a power switch, 2 is a first temperature detector (b) for detecting room temperature, and a temperature detector 3 is formed of a thermistor or the like.
A / D conversion device, 4 is a switch section for operating modes and the like, 5 is a microcomputer, and cooling / heating capacity calculation means (c) for determining the cooling / heating capacity by the input from the first temperature detector (b) and cold / hot air By inputting the second temperature detector (e) for detecting the blowout temperature of the above, the lower blowout time calculation means (f) (described later) for determining the lower blowout time and the room temperature change near the set temperature during the cooling and heating operation. Further, a cooling / heating capacity switching means (i) for periodically changing the high cooling / heating capacity and the low cooling / heating capacity is configured, and has an input circuit 8, a CPU 9, a memory 10 and an output circuit 11. A switch unit 4 for setting a set temperature, an operation mode, etc., and a room temperature detected by the temperature detector 2 are input to the input circuit 8 via the A / D converter 3. The cooling and heating capacity varying device 12 uses the output from the output circuit 11 to compress the compressor 7.
The heating and cooling capacity is controlled by changing the rotation speed of. Reference numeral 13 is a temperature detector that constitutes a second temperature detector (e) that detects a blowout temperature of cold air temperature provided at an outlet (not shown) of an indoor unit of the air conditioner, and 14 is a drive circuit, The reciprocating driving cycle of the vertical deflection louver (g), which is disposed at the outlet and vertically deflects the blown airflow, is constant, and the vertical deflection louver 16 moves downward according to the outlet temperature of the second temperature detector (e). Of the upper and lower deflection louvers that reciprocate the blowing direction of the blown airflow by the output from the output circuit 11 as described above. ) Servo motor 15
Is to control.

Next, the operation of the third embodiment will be described with reference to FIG. 10 and FIG. 11 by dividing the cooling operation into the high-low cooling capacity operation of the first stage operation and the vertical deflection louver operation of the second stage operation.

FIG. 10 shows the flow of the high / low cooling capacity operation of the first stage operation of the third embodiment, and FIG. 11 shows the operation control of the vertical deflection louver of the second stage operation of the third embodiment. First, the third
The high / low cooling capacity operation of the first stage operation of the embodiment will be described with reference to FIG.

First, when the power switch 1 is turned on, the flowchart shown in FIG. 10 starts. Set temperature Ts in step S1
Is set. In step S2, the first temperature detector 2 (first c
The detected room temperature Ta is input, the temperature difference ΔT between the set temperature Ts and the room temperature Ta is calculated in step S3, the room temperature is higher than the set temperature in step S4, and the operation mode becomes the normal mode in step S5. Or the temperature difference ΔT between the set temperature and the room temperature is, for example, 1 deg or more, step S11
In step S12, the cooling / heating capacity is calculated from ΔT, and the compressor is operated by the cooling / heating capacity varying device 12 in step S12. Again step
If the room temperature is lower than the set temperature in S4, the process proceeds to step S10, the compressor 7 is turned off, and the cooling operation is stopped. The above is the case of the normal mode. Next, the case where the operation mode is changed to the change mode by the switch 4 will be described. Step S5
It is determined that the change mode switch has been turned on, and the absolute value of the temperature difference ΔT between the set temperature and room temperature is, for example, 1 deg.
Change mode is entered when: In step S6, the current cooling / heating capacity is used as the reference capacity, and the high cooling operation is performed with the capacity increased by, for example, 10%, and in step S7, it is waited for a certain period of time. After a lapse of a certain period of time, in step S8, the cooling and heating capacity is reduced by, for example, 1% from the reference capacity, and low cooling operation is performed. If the absolute value of the difference between the room temperature and the set temperature is larger than, for example, 1 deg and the room temperature is near the set temperature in step S5, the process branches to step S11 to enter the room temperature control in the normal mode. As a result, the change mode is set only when the room temperature is near the set temperature, and the room temperature is controlled so as to change near the set temperature.

FIG. 13 is a control characteristic diagram when the cooling operation is performed based on this embodiment. The horizontal axis represents time, and the vertical axis represents temperature and cooling capacity. Set the operation mode to the normal mode and wait for time T1.
When the operation of the air conditioner is started, the room temperature drops toward the set temperature indicated by the broken line. Since the cooling capacity is determined from the difference between the set temperature and the room temperature, the cooling capacity decreases as the room temperature decreases, and at time T2, the difference between the room temperature and the set temperature becomes small and the cooling capacity becomes stable along with the cooling capacity. When the change mode is set at the time T3, the cooling capacity changes every fixed time t as shown in the figure, so that the room temperature periodically changes in the vicinity of the set temperature. This change in room temperature stimulates the thermoreceptor of the skin of the user, and activates the physiological function of the user and the activity level of the cerebrum, so an energy saving effect can be expected.

However, in the case where there is a downward airflow during cooling in FIG. 16, according to the experimental results of the feeling of comfort when the blowing temperature and the downward blowing time change, the feeling of comfort changes greatly depending on the blowing temperature and the downward blowing time. It can be seen that it is necessary to determine the optimum reciprocating cycle of the louver according to the blowing temperature as in the present embodiment, in order to enhance the comfort feeling by the downward blowing air current.

Next, similarly, the operation control of the vertical deflection louver (g) of the third embodiment will be described with reference to FIG. 11 centering on the downward blowing time varying means (n).

In FIG. 11 of the drawing, the operation starts when the power switch 1 is turned on. In step T1, the set temperature is input from the switch unit 4 and the room temperature is input from the temperature detector 2. In step T2, the vertical deflection louver 16 is moved downward and stopped by the rotation of the servo motor 15. In step T3, the outlet temperature is detected by the second temperature detector 13, and in step T, the maximum outlet time in the downward direction: Xsec. Is calculated according to the outlet temperature, as shown in the operation explanatory diagram of FIG. At T5, the time in that stop state is counted, and at step T6 it is determined whether the stop time of the vertical deflection louver 16 has exceeded the maximum stop time.If not, the vertical deflection is performed as at step T7. The operation of the louver 16 is continued with the louver 16 stopped, and the counting in step T5 is repeated. When the time is over, the vertical deflection louver 16 moves upward due to the rotation of the servo motor 15 in step T8 and stops. The maximum blowout time of the louver in the upward direction: (30−X) sec. Is calculated in step T9, the time in the stopped state is counted in step T10, and the stop time of the vertical deflection louver 16 is the maximum stop time in step T11. If it is not over, the operation is continued with the vertical deflection louver 16 stopped as in step T12, and the count in step T10 is repeated. When the time is exceeded, the vertical deflection louver 16 moves downward due to the rotation of the servo motor 15 in step T2 and stops, and the operation is continued.

Fig. 14 shows the relationship between the thermal sensation of a person when there is a downward airflow during cooling and when it does not (when blowing up). In this case, the relationship of human comfort in the case of () is obtained from some experiments. There is a cooling effect by the air flow compared to the case without the downflow airflow, and the comfort feeling improves as the room temperature rises, so even if the room temperature is raised compared to the case without the downflow airflow You can expect the energy saving effect because you can get the same comfort.

However, when there is a downward airflow during cooling in FIG. 16, according to the experimental results of the feeling of comfort when the blowing temperature and the downward temperature change, the feeling of comfort greatly changes depending on the blowing temperature and the downward blowing temperature. It can be seen that, in order to enhance the feeling of comfort by the downward airflow, it is rather uncomfortable unless the blowing temperature and the downward airflow time are sufficiently taken into consideration.

The above description is for cooling, but the same is true for heating, and similar effects can be obtained in all air conditioners whose cooling capacity can be varied.

Next, the fourth embodiment will be described with reference to FIGS. 18 to 22.

FIG. 18 is an electric circuit diagram of the fourth embodiment of the present invention, FIG. 19 is a diagram showing the operation of the vertical deflection louver, and FIG. The figure is a flowchart (2) for controlling the latter stage operation of the fourth embodiment, and FIG. 22 is a diagram showing the relationship between the blowout temperature and the louver reciprocating cycle.

In Figure 18, power switch, temperature detector 2, A /
The D converter 3, the switch unit 4, the microcomputer 5, the compressor 7, the cooling and heating capacity varying device 12, and the second temperature detector 13 are the same as those in the third embodiment shown in FIG. Reference numeral 14 denotes a drive circuit, which maintains a constant ratio of up-blowing and down-blowing by a vertical deflection louver (e) which is arranged at the outlet and vertically deflects the blown airflow, and blows out from the second temperature detector (g). A vertical deflection louver reciprocating drive cycle varying means (j) for varying the reciprocating drive cycle of the vertical deflection louver (e) according to the temperature is configured, and the output from the output circuit 11 changes the blowing direction of the blowing airflow. The servo motor 15 that reciprocally drives the louver 16 is controlled.

Next, the operation of the fourth embodiment will be described for the cooling operation with reference to the flowcharts of FIGS. 20 and 21.

FIG. 20 is a flow chart (1) for controlling the front stage operation of the fourth embodiment, and FIG. 21 is a flow chart (2) showing the vertical deflection louver operation control of the fourth embodiment. Fourth
The operation of the high / low cooling capacity operation, which is the first stage operation of the cooling operation of the embodiment, is the same as that of the third embodiment described with reference to the flowchart of FIG. The operating characteristics are also the same as those of the third embodiment described with reference to FIG.

Similarly, the operation control of the vertical deflection louver (e) in the latter stage operation of the fourth embodiment will be described with reference to the flowchart of FIG.

In FIG. 21 of the drawing, when it is determined that the change mode switch is turned on in step F101, the set temperature is input from the switch portion 4 and the room temperature is input from the temperature detector 2, and step F1
In 02, the up / down blowing operation ratio (for example, 2: 1) of the vertical deflection louver is set, and in step F103, the servo motor 15 rotates to cause the vertical deflection louver 16 to move downward and stop. In step F104, the outlet temperature is detected by the second temperature detector 13, and in step F105, as shown in the operation explanatory diagram of FIG. 22, the reciprocating drive operation cycle time of the vertical deflection louver 16 is Xsec. It is calculated. As shown in the figure, the reciprocating drive operation cycle time is longer as the blowout temperature is higher (the downblow time in one cycle is also longer), and the cooling effect by the airflow to the user is increased in a comfortable state. In step F106, the maximum downward blowing stop time: X / 3sec. Is calculated, and in step F107, the time in the stopped state is counted, and in step F108, the stop time of the vertical deflection louver 16 exceeds the maximum stop time. Judgment is made, and if time is not over, vertical deflection louver as in step F109
The operation of 16 continues while stopped, and the count in step F107 is repeated. When time runs out, step
Rotation of the servo motor 15 at F110 causes vertical deflection louver
16 moves upward and stops. In step F111, the maximum blowing time of the louver in the upward direction: 2X / 3sec. Is calculated,
In step F112, the time in the stopped state is counted, and in step F113, it is determined whether or not the stop time of the vertical deflection louver 16 exceeds the maximum stop time, and if the time does not exceed, as in step F114. The vertical deflection louver 16 continues to operate while stopped, and step F1
The count at 12 is repeated. When time runs out,
In step F103, the rotation of the servo motor 15 causes the vertical deflection louver 16 to move downward and stop, and the operation is continued.

The experimental results of the above operation show that the relationship between the thermal sensation of a person with and without the downward airflow during cooling is the same as in FIG. The relationship of human comfort was similar to that shown in FIG. Compared with the case where there is no downward airflow, there is a cooling effect due to the airflow, and the comfort level improves as the room temperature rises.
Energy saving effect can be expected because the same feeling of comfort can be obtained even when the room temperature is raised compared with the case where there is no downward airflow.

Next, a fifth embodiment of the present invention will be described with reference to FIGS. 1a, 2 and 23.

Step Fsb1 which is a subroutine provided between step Fsb2 and step F007 which is a subroutine provided between step F007 and step F008. Step Fsb1 is an initial setting routine of step Fsb2, which sets a setting flag (= 1) and resets the integrated time of the lower blow-up and the upper blow-out, and has no relation to the operation. The cooling capacity control that accompanies the room temperature control except step Fsb2 is exactly the same as the flow of the conventional example, and performs the same operation. That is, the power switch 1
When is turned on, this flowchart starts, and as a result, the room temperature Tr repeatedly rises and falls between the high temperature set value Th and the low temperature set value Tl near the set temperature within a predetermined time to.

The main feature of the fifth embodiment is step Fsb2,
FIG. 24 is a flowchart of this subroutine. When branching to this subroutine, the setting flag is checked in step Fs01, and the flag is set. That is, when the setting is necessary, the process branches to step Fs02, and when the flag is not set, that is, when the setting is unnecessary, the process branches to step Fs06. Since the setting flag is set in the initial setting subroutine of this subroutine, the process first proceeds to step Fs02. The outlet temperature tf of the air conditioner is measured in step Fs02, and the lower outlet time and the upper outlet time shown in FIG. 25 are calculated in step Fs03.

FIG. 25 is a control characteristic diagram of the outlet temperature tf versus the lower outlet time by the vertical deflection louver 17, as shown in the figure, when the outlet temperature tf is high, the lower outlet time is long, and when the outlet temperature tf is low, the outlet outlet tf is lower. The time is in a short relationship, and the lower outlet time is calculated according to the outlet temperature tf at that time. Further, the upper blow-out time is calculated from the calculated lower blow-out time with a fixed cycle. The case of the figure shows the case of a period of 55 s. Step F
At s04, the drive circuit 15 and the motor 16 are operated by the output of the output circuit 10 of the microcomputer 5, and the vertical deflection louver 1
7 rotates, and the blowing airflow is set to the downward blowing. Next, in step Fs05, the setting flag is reset and the process returns to the main routine.

On the other hand, if the setting flag is not set (= 0) in step Fs01, the process proceeds to step Fs06, and if the blowing direction at that time is downward blowing, the downward blowing time is integrated in step Fs07. Next, in step Fs08, the set step Fs
03 The bottom blowing time is compared with the cumulative time of the bottom blowing performed in step Fs07, and if not finished, the process returns to the main routine. If it is determined in step Fs08 that it is finished, step Fs
At 09, the drive circuit 15 and the motor 16 are operated by the output of the output circuit 10 of the microcomputer 5, and the vertical deflection louver 1
7 rotates, and the blowing airflow is set to upper blowing. Step F
In s10, the lower blowout integrated time is reset and the process returns to the main routine.

On the other hand, in step Fs06, if the blowing direction is upward blowing, branch to step Fs11, as in the case of the downward blowing, the upper blowing time is integrated, in step Fs12, step Fs03
The upper blowout time calculated from the blowout temperature tf is compared with the integrated time, and if not finished, the process returns to the main routine. In the case of the end, the setting flag is set to the setting side in step Fs13 (= 1), the upper blowout integrated time is reset in step Fs14, and the process returns to the main routine. In this way, in this subroutine, the cycle is kept constant, and the lower blow operation and the upper blow operation according to the blow temperature at that time are repeated.

FIG. 26 is a timing chart of control characteristics when the cooling operation is performed based on the fifth embodiment. The horizontal axis represents time t, and the vertical axis represents the cooling capacity, room temperature, outlet temperature, and lower outlet temperature, respectively. When the operation mode is set to the normal mode and the operation of the air conditioner is started at time T1, the room temperature decreases toward the set temperature indicated by the broken line. Since the cooling capacity is determined from the difference between the set temperature and the room temperature, the cooling capacity decreases as the room temperature decreases, and at time T2, the difference between the room temperature and the set temperature decreases, and the cooling capacity becomes stable. Time T3
When the change mode is set in (1), the cooling capacity changes periodically as shown in the figure, so the outlet temperature is affected by the room temperature and the cooling capacity and changes as shown in the figure. As a result, the room temperature changes periodically near the set temperature. On the other hand, in the change mode at time T3, the lower outlet temperature changes as illustrated due to the changing outlet temperature.

When the lower outlet temperature changes, the air flow hitting the user changes, which can be considered to change the amount of irritation of the user. It is considered that this stimulus is determined by the time the airflow hits the user and the temperature of the airflow. The longer the airflow hits the user, the larger the stimulation amount becomes, and the lower the temperature of the airflow, the larger the stimulation amount becomes. The relationship between the downward blowing time and the blowing temperature shown in FIG. 25 is intended to make the stimulation amounts by the air flow substantially equal. Further, since the outlet temperature changes depending on the cooling capacity and the lower outlet time changes depending on the outlet temperature, when the user views the changing airflow, the airflow changes are random and are close to the changes of the natural wind. The natural breeze is said to be comfortable. Stimulation due to changes in room temperature and changes in the airflow comfortably stimulate the user's skin temperature receptors, activate physiological functions and the cerebrum, and are more comfortable and comfortable than the normal mode in which the room temperature is controlled at a constant level. It creates a good healthy environment.

In the fifth embodiment, the case where the normal mode and change mode selection switches are provided has been described.
It does not matter even if there is no selection switch and the change mode is always entered.

Further, in the above embodiment, the case where the change mode is entered when the room temperature is in the vicinity of the predetermined temperature has been described, but the change mode may be always entered.

Furthermore, the case of cooling is explained above, but the same applies to the case of heating, and the same effect can be obtained in all air conditioners whose cooling and heating capacity can be varied.

Next, a sixth embodiment of the present invention will be described with reference to FIGS. 1a, 2 and 27.
This will be described with reference to FIGS. FIG. 1a is an electric circuit diagram of a certain embodiment of the air conditioner according to the present invention, and FIG.
The disassembled perspective view of the wind direction deflecting device of this air conditioner is shown.

The configuration of the sixth embodiment in FIG. 1a of the drawing is the same as that of the fifth embodiment except for the portions described below, and thus the duplicate description thereof will be omitted.

The control of the blown airflow, which is the feature of the sixth embodiment, will be described below.

In FIG. 1a of the drawings, 13 is a second temperature detector arranged at a discharge port (not shown) of an indoor unit of the air conditioner for measuring the temperature of the blown airflow, 14 is an A / D converter, 15
Is a drive circuit for controlling a motor 16 such as a servomotor to which a vertical deflection louver 17 for changing the blowing direction of the blown airflow shown in FIG. 2 is attached by the output of the output circuit 10.

Next, the operation of the sixth embodiment will be described by taking the case of the cooling operation as an example.
Description will be made with reference to FIGS. 27 and 28. 27 and 28 are flowcharts of control operation sequences including the heating / cooling capacity calculating means stored in the microcomputer 5, respectively.

In FIG. 27, steps F003 and F004 are different from the corresponding flowchart of the conventional example (FIG. 38).
Step Fsb1 which is a subroutine provided between step Fsb2 and step F007 which is a subroutine provided between step F007 and step F008. Step Fsb1 is the initial setting routine of step Fsb2, which sets the lower blowout time, sets the setting flag (= 1), and resets the integrated time of the lower blowout and the upper blowout, and is not related to the operation. Step
The cooling capacity control associated with the room temperature control except Fsb2 is exactly the same as the conventional example, and operates in the same manner. That is, when the power switch 1 is turned on, this flowchart starts, and as a result, the room temperature Tr repeatedly rises and falls between the high temperature set value Th and the low temperature set value Tl near the set temperature within a predetermined time to.

The main feature of the present invention is step Fsb1, and FIG. 28 is a flowchart of this subroutine. If you branch to this subroutine, the setting flag is checked in step Fs01, and when the flag is set, that is, when the setting is necessary, the step Fs02 is set. When the flag is not set, that is, when the setting is unnecessary, the step is set. Branch to Fs06. Since the setting flag is set in the initial setting subroutine of this subroutine, the process first proceeds to step Fs02. In step Fs02, the outlet temperature tf of the air conditioner is measured, and in step Fs03, the upper outlet time shown in FIG. 29 is detected.

FIG. 29 is a control characteristic diagram of the outlet temperature tf versus the upper outlet time by the vertical deflection louver 17, and as shown in the figure, the upper outlet time is short when the outlet temperature tf is high, and the upper outlet time is low when the outlet temperature tf is low. Since the time is long, the upper blowing time is calculated according to the blowing temperature tf at that time. In step Fs04, the output of the output circuit 10 of the microcomputer 5 causes the drive circuit 1
5. The motor 16 operates, the vertical deflection louver 17 rotates, and the blowing airflow is set to the downward blowing. Next, step Fs05
Then, the setting flag is reset and the process returns to the main routine.

On the other hand, if the setting flag is not set (= 0) in step Fs01, the process proceeds to step Fs06, and if the blowing direction at that time is downward blowing, the downward blowing time is integrated in step Fs07. This lower blowing time is the initial setting subroutine,
It is preset to about 5 to 20 seconds. Next, in step Fs08, the set lower blowout time is compared with the integrated time of the lower blowout performed in step Fs07, and if not finished, the process returns to the main routine. If it is determined in step Fs08 that the operation is finished, the process proceeds to step Fs09, in which the output of the output circuit 10 of the microcomputer 5 causes the drive circuit 15 and the motor 16 to operate, the vertical deflection louver 17 to rotate, and the blowing airflow to blow upward. Is set. In step Fs10, the lower blowout integrated time is reset, and the process returns to the main routine.

On the other hand, in step Fs06, if the blowing direction is upward blowing, branch to step Fs11, as in the case of the downward blowing, the upper blowing time is integrated, in step Fs12, step Fs03
The upper blowout time calculated from the blowout temperature tf is compared with the integrated time, and if not finished, the process returns to the main routine. In the case of the end, the setting flag is set to the setting side in step Fs13 (= 1), the upper blowout integrated time is reset in step Fs14, and the process returns to the main routine. In this way, in this subroutine, the operation of the upper blow-out according to the blow-out temperature at that time and the preset operation of the lower blow-out are repeated.

FIG. 30 is a timing chart of control characteristics when the cooling operation is performed based on the sixth embodiment. The horizontal axis is time t
And the vertical axis represents the cooling capacity, the room temperature, the blowing temperature, and the upper blowing time, respectively. Set the operation mode to normal mode and
When the operation of the air conditioner is started at T1, the room temperature drops toward the set temperature indicated by the broken line. Since the cooling capacity is determined from the difference between the set temperature and the room temperature, the cooling capacity decreases as the room temperature decreases, and at time T2, the room temperature has a small difference from the set temperature and stabilizes together with the cooling capacity. Time T3
When the change mode is set in (1), the cooling capacity changes periodically as shown in the figure, so the outlet temperature is affected by the room temperature and the cooling capacity and changes as shown in the figure. As a result, the room temperature changes periodically near the set temperature. On the other hand, when the change mode is set at time T3, the upper blowing time changes as illustrated due to the changing blowing temperature.

When the upper blowing time changes, the air flow hitting the user changes, which can be considered to change the amount of stimulation of the user. It is considered that this stimulus is determined by the time the airflow hits the user and the temperature of the airflow. The longer the airflow hits the user, the larger the stimulation amount becomes, and the lower the temperature of the airflow, the larger the stimulation amount becomes. The relationship between the upper blowing time and the blowing temperature shown in FIG. 29 is intended to make the stimulation amounts by the air flow substantially equal. Stimulation due to changes in room temperature and changes in the airflow comfortably stimulate the user's skin temperature receptors, activate physiological functions and the cerebrum, and are more comfortable and comfortable than the normal mode in which the room temperature is controlled at a constant level. It creates a good healthy environment.

In the sixth embodiment, the case where the normal mode and change mode selection switches are provided has been described.
It does not matter even if there is no selection switch and the change mode is always entered.

In the above embodiment, the case where the change mode is entered when the room temperature is in the vicinity of the set temperature is described, but the case where the change mode is always entered may be used.

Furthermore, the case of cooling is described above, but the same applies to the case of heating, and the same effect can be obtained in all air conditioners that can vary the cooling and heating capacity.

Next, a seventh embodiment of the present invention will be described with reference to FIGS.
This will be described with reference to the drawings.

FIG. 31 is an electric circuit diagram showing a seventh embodiment of the air conditioner according to the present invention, and FIG. 32 is an exploded perspective view of the wind direction deflecting device of the air conditioner.

In FIG. 31, 1 is a power switch, 2 is a thermistor or the like, which is a first temperature detector for detecting the room temperature, 3 is an A / D converter, and 4 is a switch section for operating modes and the like.

Next, the operation of the seventh embodiment will be described with reference to the cooling operation in the 32nd operation.
This will be described with reference to FIGS.

FIG. 33 is a flow chart including the heating / cooling capacity calculation means stored in the microcomputer 5, and FIG. 34 is a characteristic diagram for determining the downward blowing time of the vertical deflection louver from the temperature of the indoor heat exchanger.

First, when the power switch 1 is turned on, the flowchart shown in FIG. 33 starts. 33, the set room temperature Ts is set in step F001, the high temperature set value Th is set in step F002, and the constant temperature set value Tl is set in step F003.
The room temperature Tr is detected in step F004, the room temperature control mode is selected in step F005, and the integrated time is reset in step F006. If the change mode is not selected in step F007, the process proceeds to step F008, the cooling capacity for keeping the room temperature Tr constant at the set value Ts is calculated, and the operation is continued. The above is the case of the normal mode, which is exactly the same as the conventional case.

Next, a seventh embodiment, which is characterized in that the operation mode is changed to the change mode with the switch 4, will be described. Step F0
If the change mode is selected in 07, proceed to step F009,
If the room temperature control mode is set, the cooling and heating capacity is operated with high capacity in step F010, and the process branches to step F011. The temperature Tf of the indoor heat exchanger is detected in step F011, the downstream time of the airflow is determined from the graph of FIG. 34 in step F012, and the direction of the vertical deflection louver is controlled in step F013. The room temperature Tr is detected in step F014, the time is integrated in step F015, and the process proceeds to step F016. If the fixed time has not elapsed in step F016, step F0
If the room temperature Tr is higher than the constant temperature set value Tl in step F017, the process branches to step F011. If a certain period of time has passed in step F016 or if the room temperature Tr is lower than the constant temperature set value Tl in step F017, the process proceeds to step F018, the mode of blowout temperature control is set, and the process branches to step F006. When the blowout temperature control mode is set in step F009, the cooling and heating capacity is operated with low capacity in step F019, and the process branches to step F020. In step F020, the temperature Tf of the indoor heat exchanger is detected, and in step F021, the downflow time of the air flow is determined from the gram of FIG. 34, and in step F022,
The direction of the vertical deflection louvers is controlled. Room temperature Tr is detected in step F023, time is integrated in step F024,
Go to step F025. If the fixed time has not elapsed in step F025, the process proceeds to step F026, and in step F026, the room temperature is reached.
If Tr is lower than the high temperature set value Th, the process branches to step F020. If a certain time has elapsed in step F025 or if the room temperature Tr is higher than the high temperature set value Tl in step F026, the process proceeds to step F027, the room temperature control mode is set, and the process branches to step F006. As a result, the room temperature control and air flow stimulation modes are alternately repeated so that the room temperature fluctuates within a certain temperature range in a cycle that does not exceed a certain time, and the air flow is used according to the temperature of the indoor heat exchanger. Hit the person periodically.

FIG. 35 is a control characteristic diagram when the cooling operation is performed based on the seventh embodiment. The horizontal axis represents time, and the vertical axis represents the temperature, room temperature and cooling capacity of the indoor heat exchanger. When the operation mode is set to the normal mode and the operation of the air conditioner is started at time T1, the room temperature decreases toward the set temperature indicated by the broken line.
Since the cooling capacity is determined from the difference between the set temperature and the room temperature, the cooling capacity decreases as the room temperature decreases, and the difference between the room temperature and the set temperature becomes small at time T2, and stabilizes together with the cooling capacity. When the change mode is set at time T3, as shown in the figure, the room temperature fluctuates by repeating room temperature control and blowout temperature control within a certain temperature range.

This change in room temperature and the air flow hitting the user stimulate the skin's thermoreceptors. Therefore, it can be considered that the thermoregulatory function works to activate the physiological function of the user and the activity level of the cerebrum. Fig. 36 shows the relationship between the human thermal sensation (sensation of being hot and cold) and room temperature during cooling operation, obtained from several experiments. Compared to the case where the room temperature of A is constant, the case of B in which the room temperature and the air flow are changed has the effect of feeling cool even at the same temperature. When the room temperature and the air flow are changed, the same thermal sensation can be obtained even when the set temperature is higher than when the air flow is not changed, which is economically effective.

Although the above embodiment has described the case where the selection switch for the normal mode and the change mode is provided, the change mode may be always entered without the selection switch.

The above description is for cooling, but the same is true for heating, and the same effect can be obtained in all air conditioners whose cooling / heating capacity can be varied.

In addition, as described at the beginning of the above-mentioned embodiment, in all the above-mentioned embodiments, the air conditioner is arranged in the upper part of the room, and in this case, the down-blowing time is the time when the occupant is exposed to the wind, The time is the time when the residents are not exposed to the wind.

The present invention also includes the case where the air conditioner is installed at an arbitrary height in the room, for example, at the bottom as described above. When the time is not applied, the blowing time is set right above. Therefore, the structure can be easily considered according to the above-mentioned embodiment, and the same operation and effect as those of the above-mentioned embodiment can be obtained.

〔The invention's effect〕

As described above, according to the present invention, the room temperature is controlled by repeating the room temperature control and the outlet temperature control, and the airflow is periodically applied to the user according to the outlet temperature or the temperature of the indoor heat exchanger. Since it can stimulate the physiological function of the user and the cerebrum by giving a stimulus due to the air flow and a stimulus of room temperature fluctuation, it is more comfortable than the conventional case where the air conditioning capacity is controlled so that the room temperature becomes constant at the set temperature. It is possible to provide a comfortable environment. In addition, it is economical because the temperature can be set low when heating at the set temperature and high when cooling.
