Abstract

PURPOSE:To diffuse down the air of a high temperature when an ON timer is timed up by diffusing up a louver in a heating operation in response to a set operation starting time, and regulating a room temperature to a higher temperature than a set temperature by diffusing down the louver at the time of getting up. CONSTITUTION:A temperature in a room is so set by a temperature setter 9 before sleeping as to hold a predetermined temperature, a get-up time is set by an ON timer of a time setter 10, a cooling/heating changeover switch 11 is set to heating, and a louver is so rotated based on a diffuse-up signal as to laterally diffuse the air. When it becomes the get-up time set by the setter 10, a diffuse-down signal is output as a second signal from a time discriminator 14. The diffuse-down signal is applied to a louver controller 20 to so rotate the louver as to direct the air diffusing direction to downward. In this case, the air of a high temperature near a ceiling is further heated by a heat exchanger, diffused to a floor surface in the room, and hence a user can get up without feeding cold.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An air conditioner according to the present invention will be described below with reference to the drawings. 1 is a controller 3 for controlling an air conditioner according to the first aspect of the present invention, and FIG. 2 is a flow chart showing a control sequence of the air conditioner. Since the air conditioner has the same configuration as that described in the section of the related art based on FIG. 7, the same reference numerals are given to the parts. FIG. 3 shows the configuration of the indoor unit 1 of the air conditioner. When this explanation is given first, the indoor unit 1 has an indoor heat exchanger 5 housed in an outer frame 4 and air flowing into the indoor heat exchanger 5. Room temperature sensor 6 that detects the temperature of the air, a fan 7 that rotates by a motor to let air flow into the indoor heat exchanger 5 and let out the air after heat exchange, and a motor 8 that rotates to blow out the air. The louver 2 changes the blowing direction, and the controller 3 controls the entire indoor unit 1. The compression season, the outdoor heat exchanger, etc., which are connected to the indoor heat exchanger 5 by piping to form a refrigeration cycle, are housed in an outdoor unit (not shown). The indoor heat exchanger 5 used functions as a condenser during heating and as an evaporator during cooling.

Next, the controller 3 shown in FIG. 1 will be described. The controller 3 includes a temperature setting device 9, a time setting device 10,
An operation panel 12 including a cooling / heating switch 11 and the like is connected. This operation panel 12 is to be attached to the main body of the indoor unit 1 and is attached to the wall. The temperature setter 9 allows the user to set a desired room temperature. The time setter 10 can set the time when the indoor unit 1 is operated or stopped, and is a so-called on / off timer. The cooling / heating changeover switch 11 is a switch for operating the indoor unit 1 for either cooling or heating.
The controller 3 is composed of a microcomputer and peripheral circuits. When the time is set in the time setter 10, the converter 13 is supplied with an operation command signal A, and the converter 13 is operated.
Gives the time setting signal B to the time discriminator 14. The time discriminator 14 monitors the passage of time based on the time setting signal B from the converter 13 and the time signal C output from the clock 15. The cooling / heating discriminator 16 gives a cooling / heating instruction signal D to the time discriminator 14 in response to an instruction for cooling or heating by the cooling / heating changeover switch 11. The time discriminator 14 compares the time setting signal B from the converter 13 and the time signal C from the clock 15, and when the time signal C is t hours before the time setting signal B, the heating / cooling instruction signal D indicates the heating. During the operation, the air conditioning instruction signal E, the upshift instruction signal F, and the H level signal as the upper blowing signal are output to the louver controller 20. When the cooling / heating instruction signal D indicates cooling, the upshift instruction signal F is not output, and only the air conditioning instruction signal E and the H level signal as the upper blowing signal are output. The air conditioning instruction signal E is a signal that permits the operation of the air conditioner. The shift-up instruction signal F is the temperature shifter 1
7, the temperature shifter 17 outputs a shift-up signal H higher than the temperature setting signal Ts based on the temperature set in the temperature setting device 9. This shift up signal H
Is a signal for instructing to control the room temperature by setting Ts + β higher than the temperature setting signal Ts based on the temperature set in the temperature setter 9 as shown in FIG. This signal lasts for a predetermined time t + α. The upper blowing signal is a signal in the H state as shown in FIG. 4C, and is a signal for rotating the louver 2 in order to blow the air upward. The air conditioning instruction signal E and the upshift signal H are provided to the arithmetic and control unit 18, respectively. Based on the air conditioning instruction signal E, the temperature setting signal Ts from the temperature setter 9, and the shift-up signal H from the temperature shifter 17, the arithmetic and control unit 18 determines the rotation speed of the compressor 5a and the rotation speed of the blower fan. And the number of rotations of the outdoor fan 19 is set, and the operation of the compressor 5a, the blower fan 7, and the outdoor fan 19 is instructed. Then, after the time discriminator 14 outputs the H level signal as the upper blowing signal to the air conditioning instruction signal E, the shift up instruction signal F, and the louver control signal I, when the predetermined signal t elapses, the lower blowing signal to the louver control signal I. Output an L level signal. During the cooling operation, the upper outlet signal (H level signal) remains unchanged from the start of operation, which is the same as the conventional one. This lower blow signal is an L level signal as shown in FIG. 4C, and is a signal which is given to the louver controller 18 to rotate the louver 2 so that the blow of air is directed downward.

Based on the controller 3 having such a configuration, the operation of the indoor unit 1 according to the present invention of item 1 will be described along the flow chart of FIG.

First, before going to bed, the temperature setter 9 is set to a temperature for keeping the room at a predetermined temperature, the on-timer of the time setter 10 is used to set the wake-up time, and the cooling / heating changeover switch 11 is set to heating.

In step 21, it is judged whether or not the incoming timer is set in the time setting device 10. If the incoming timer is not set, normal operation control of the indoor unit 1 is performed. If the incoming timer has been set, the routine proceeds to step 22. At this time, the converter 13 receives the operation command signal A from the time setting device 10, and gives the time discriminating device 14 a time setting signal B corresponding to the set ON timer.

In step 22, the time discriminator 14 determines based on the time setting signal B whether or not the on-timer for waking up is set. That is, if this time is between 4:00 am and 8:00 am, it is determined that the on-timer for wake-up has been set, and the process proceeds to step 23. If it is not within the above time, it is not the on-timer for wake-up. After making a determination, the routine proceeds to step 24, where the indoor unit 1 is operated based on the operating conditions set on the operation panel 12, and normal operation control is performed. In the present embodiment, the determination of the wake-up on-timer is determined based on the set time, but if a wake-up switch such as another "Good morning timer switch" is provided in advance, this determination becomes unnecessary, and the "Good morning timer" Whether or not the "switch" has been operated is determined, and if so, this control (from step 23) may be performed.

In step 23, it is judged whether or not the time signal C is 20 minutes before the time of the time setting signal B, and if it is not 20 minutes before, the elapsed time is continuously monitored, and if it is 20 minutes before, the step 25 is executed. Move on to.

In step 25, it is judged whether or not the heating operation is being performed. If the heating / cooling switching switch 11 is set to heating, the process proceeds to step 26, and if it is not the heating operation, the process proceeds to step 27 and the cooling operation is performed.

In step 26, the louver 2 is rotated based on the upper blowing signal so that the air is blown laterally as shown in FIG. 5 (a).

In step 28, the temperature is higher than the temperature setting signal Ts by 5 ° C., that is, the shift-up temperature (Ts +
5) and the room temperature signal Ta are compared by the arithmetic controller 18, and if the room temperature signal Ta is not smaller than the shift-up temperature (Ts + 5), it is determined that the room temperature has reached the shift-up temperature (Ts + 5), and the process proceeds to step 29. The arithmetic and control unit 18 stops the compressor 5a, the blower fan 7, and the outdoor fan 19. The room temperature signal Ta indicates the shift-up temperature (Ts +
If it is smaller than 5), go to Step 30.

Note that the meaning of blowing out high-temperature air by the shift-up signal H is to retain high-temperature air in the vicinity of the ceiling, raise the ceiling surface, and radiate heat from this ceiling surface to the floor, which is a sleeping room. This is because the temperature is adjusted to an appropriate temperature with almost no air blown near the surface.

At step 30, the air conditioning instruction signal E, the shift-up signal H, and the temperature setting signal Ts are given to the arithmetic and control unit 18, and the arithmetic and control unit 18 is based on these signals, the compressor 5a, the blower fan 7, and The outdoor fan 19 is driven.

As shown in FIG. 5B, the temperature distribution in the room at this time is such that the air having a relatively low temperature when the operation of the indoor unit 1 is started is blown out laterally near the ceiling, and The rising air is also blown out in the vicinity of the ceiling, and becomes lower in temperature as it approaches the floor surface.

At step 31, it is judged whether or not the wake-up time set in the time setting device 10 has come. If it is not the wake-up time, the process returns to step 28 to adjust the room temperature. If it is the wake-up time, the process proceeds to step 32.

At step 32, the second time is determined from the time discriminator 14.
A downward blowing signal as a signal is output. This downward blowing signal is given to the louver controller 20 to rotate the louver 2 so that the blowing direction of air is downward as shown in FIG. 6 (a). At this time, as shown in FIG. 6B, the high temperature air around the ceiling is further heated in the heat exchanger by the heat exchanger and blown to the floor surface, so that the user can wake up without feeling cold.

In step 33, it is judged whether or not 10 minutes have elapsed after the wake-up time. If 10 minutes have not yet elapsed, the process returns to step 28 and the indoor temperature adjustment is continued. That is, hot air blows out to the lower part of the room for 10 minutes, which makes the wake-up comfortable. After 10 minutes, step 34
Move on to.

At step 34, the output of the upshift signal H is stopped.

At step 35, it is judged if the room temperature signal Ta is larger than the temperature setting signal Ts. That is, the normal room temperature control is resumed, and if the room temperature signal Ta is smaller than the temperature setting signal Ts, the process proceeds to step 36, and if the room temperature signal Ta is not smaller than the temperature setting signal Ts, the process proceeds to step 37.

In step 36, the compressor 5a, the blower fan 7,
Then, the outdoor fan 19 is continuously driven, and the process proceeds to step 38.

In step 37, the compressor 5a, the blower fan 7, and the outdoor fan 19 are stopped because the temperature of the room has reached the temperature indicated by the room temperature signal Ta, and the process proceeds to step 38. Then, after that, the normal heating operation with the set temperature Ts and the blowout under the louver is performed.

Although not shown in the flow chart, when an operation input is made during the main control flow, the control flow is canceled and the operation is shifted to the new operation input. For example, when a stop input is input from the operation stop switch, the control flow is released at that point and the air conditioner is stopped. In this way, it is possible to create a comfortable indoor environment without feeling the cold when getting up.

[0028]

As described above, in the air conditioner of the present invention, the heating operation of the air conditioner is started by the upper blowing according to the set operation start time, and when the wake-up is started, the louver is set to the lower blowing and the set temperature is set. Since the temperature is raised by a predetermined temperature, it is possible to create a particularly comfortable indoor environment when waking up using the entrance timer.
