[Detailed Description of the Invention] Industrial Application Field The present invention enables an air conditioner and a blower device such as an electric fan provided independently from the air conditioner to be operated in parallel in the same room. The present invention relates to air conditioners, blowers, and their operation control devices.

2. Description of the Related Art In general, systems are widely known in which an air conditioner is installed indoors to cool or heat the room to obtain an air conditioning effect.

Also, JP-A-61-52530, JP-A-61-5
As disclosed in Japanese Patent No. 2531, there is also known control that detects conditions such as humidity or air pollution during air conditioning and drives a humidifier or ventilation fan to improve comfort.

Problems to be Solved by the Invention However, in the former type of general air conditioning system, since the temperature of the entire room is controlled, the load on the air conditioner is large, and power consumption is large. This power consumption increases as the difference between the indoor set temperature and the current temperature increases.

Further, although the latter control can improve the comfort of air conditioning, it cannot reduce power consumption.

In view of the above-mentioned conventional problems, the present invention aims to provide an operation control device that can achieve the following objects.

Further, the other means is a remote control device that outputs an operating signal such as an infrared ray, an air conditioner whose operation is controlled by the signal from the remote control device, and an air conditioner that is installed independently of the air conditioner. and a blower device whose operation is controlled by a signal from the remote control device, the remote control device being set to a first operation mode in which an operation signal for the air conditioner is output; It is composed of a second operation mode that outputs a parallel operation signal of the air blower, and a selection output means that selects and outputs the first operation mode and the second operation mode.

Still other means includes an air conditioner equipped with a compressor, a heat exchanger, a blower, etc., a blower means installed indoors and operated independently of the blower of the air conditioner, and an air conditioner equipped with the air conditioner. a first signal receiving section provided in the air blower, a second signal receiving section provided in the air blowing means, and a remote control device that outputs an operation control signal such as an infrared beam to each of the first and second signal receiving sections. a first operation mode storage means storing a first operation mode in which only the air conditioner is operated, and the air conditioner and the blower are operated in parallel; a second operation mode storage means for storing a second operation mode; a selection means for selecting one of the first and second operation mode signals; and a first and second operation mode signal selected by the selection means. an output means for outputting one of the operation mode signals to the first and second signal receiving sections, and further outputting the air to the first signal receiving section in response to a signal from the remote control device. A first operating means for controlling the operation of the harmonizer is provided, and a second operating means for controlling the operation of the air blowing means in response to a second operating mode signal from the remote control device, the second signal receiving section being provided with a first operating means for controlling the operation of the harmonizer.

By using such a means, the operation control device can optionally add the feeling of cold air generated by the airflow to the air conditioning action of the air conditioner, making it possible to reduce power consumption and to maintain a uniform ambient temperature around the human body. It is possible to prevent the phenomenon of insensitivity to the feeling of cooling caused by air conditioning, that is, the curling phenomenon.

In addition, by adding a room temperature sensing function to the blower itself, it is possible to reduce the blowing capacity according to the indoor temperature, that is, once the cooling effect has progressed to a certain extent, thereby reducing the discomfort caused by excessive cooling. It can be prevented.

Next, an example of a specific configuration of the circuit shown in FIG. 2 will be explained with reference to FIG. Here, a case will be described in which the air conditioner is mainly controlled by a microcomputer, and the indoor load is temperature. moreover,
Since the circuit configurations of the remote control device 3 and the electric fan 2 may be well-known configurations, their explanations will be omitted. And Figure 1,
Components that are the same as those in FIG. 2 are given the same reference numerals and explanations will be omitted.

In the figure, reference numeral 10 denotes a microcomputer, which is equipped with an operation signal determining means 1e and a control means 1 shown in FIG. 2. 11 is a thermistor that detects room temperature;
This corresponds to the indoor load detection means 1f shown in the figure. Reference numeral 12 denotes a room temperature setting resistor for setting the room temperature, which corresponds to the set load storage means 1g in FIG.

It has speed change taps for "high speed (H),""medium speed (M)," and "low speed (L)," and is switched and operated by relays 18, 19, and 20. Further, the operation of the compressor 15 is controlled by a relay 21. Each of the relays 14b, 1B, 19
・2o and 21 are transistors 22, 23, 24, and 2 connected to each port of the microcomputer 1o, respectively.
The energization is controlled by 5 and 26. 27 is the power supply, 28
indicates a power switch.

It goes without saying that the room temperature setting and determination function or the set load correction function is not limited to the configuration shown in FIG. 3, and can be realized by program processing of a microcomputer.

Next, the operation of the system configuration described above, including FIG. 4, will be explained. Here, for convenience of explanation, the first operation mode and the case where the first operation mode changes to the second operation mode will be described.

First, the first operation mode will be explained.

The operation switch is turned on and the air conditioner (indoor unit)
1 is operated, the thermistor 11 detects the room temperature t as shown in step 1 of FIG. 4, and the comparator 13
is the indoor temperature t and the temperature t set by the room temperature setting resistor 12.
1 and continue the comparison. This operation corresponds to steps 2 and 4 in FIG. At the same time as this operation, the microcomputer 10 (operation signal judgment means 1e)
), in step 3 of FIG.
Since this is the operating mode, the indoor temperature is maintained at the set value t1 by the operations shown in steps 4 to 6.

The above operations are the basic control contents of a normal air conditioner alone, but various functional operations may be added between steps 1 to 6 as necessary.

Next, in the above operation, the remote control device 3 controls the second
When the operation mode signal is output, the microcomputer 10 moves from step 3 in FIG. 4 to step 7. That is, in response to the second operation mode signal, the operation output means 2f of the electric fan 2 outputs a signal that allows the electric fan 2 to operate to the first signal receiving section 1c of the air conditioner 1 (step 7). Then, as shown in step 8 of FIG. 4, after confirming the output of the operating signal determining means 16 of the microcomputer 1o, the microcomputer 10 operates the transistor 22 to adjust the set temperature t1 and the correction value α. The setting value is changed to the added setting value t2 (step 9).

Then, the process moves to step 10, the electric fan 2 is operated, and the cooling operation is controlled until the condition of step 11 is satisfied.

Ko (7)? The JJ operation is controlled by microcombi, -ta 1.
This is done by operating the relay 21 by the operation of the transistor 26 based on the zero signal, and causing the compressor 15 to operate intermittently.

By the above operation, the cooling effect of the airflow is added to the human body, a cold air effect can be obtained, and the room temperature is adjusted to the set value t.
2.

Here, if the power to the electric fan 2 is not turned on during the second operation mode, or if the electric fan 2 is no longer operated due to the power to the electric fan 2 being turned off during the second operation mode, etc. Since step 7 described above is not executed, the set temperature t1 is not changed. As a result, the original first operation mode continues in the room, and it is possible to prevent the room temperature from rising and causing discomfort.

Next, another embodiment of the present invention will be described based on FIG. 5.

The embodiment shown in FIG. 5 relates to the electric fan 2.
Further effects can be expected if used in the control of the previous embodiment.

That is, the electric fan 2 of this embodiment is the electric fan 2 of FIG.
In addition to the configuration, an indoor temperature detection means 2g detects the indoor temperature at the initial stage of operation, and a target value is set by subtracting a correction value of a predetermined value (for example, 2°C) from the detected value of this indoor temperature detection means 2g. temperature setting means 2h, and a speed change means 2 that reduces the rotational speed of the electric fan 2 when the detected value by the indoor temperature detection means 2g reaches a target value of the temperature setting means 2h.
1 is provided with output means 2j for outputting a deceleration signal to 1.

In FIG. 5, the driving means 2 corresponds to the motor section 2b in FIG. 1, and the blowing means 21 corresponds to the fan section 2o in FIG.

Control of the electric fan 2 having such a configuration is applied when the room has been cooled to a certain extent by the air conditioner.

Therefore, this electric fan 2 is preferably used when cooling is suddenly started from the second operation mode.

In the above embodiments, the case where a fan is used as the air blowing means or the air blowing device is explained, but the air blowing means or the air blowing device may be, for example, a circulator or
In addition to local air conditioners that have been developed in recent years, there are also air blowing means that produce a cold air effect on the human body through airflow,
Any blower device will do.

In addition, the indoor load detection of the air conditioner is not limited to room temperature, but may also detect refrigerant pressure, temperature, etc. in the refrigeration cycle, and convert it to room temperature by taking into account operating time and the like.

Furthermore, the air conditioner is not limited to a separate type, but may be an integrated type air conditioner, which is relatively difficult to increase in capacity.

Further, if necessary, the air blowing means or the air blowing device may be provided with a blowing direction variable means or an intermittent blowing means, thereby preventing the air-conditioned feeling of the negative layer from becoming distorted.

Effects of the Invention As is clear from the above embodiments, the present invention provides a cooling effect not only by temperature but also by airflow. Not only does it not make you feel like you are curled up, it improves your comfort, and because the four air currents create a cooling effect, you can set the room temperature of the air conditioner higher, which reduces power consumption accordingly. is measured. In addition, the cooling effect of this airflow causes less heat shock when leaving a room that is being cooled (and provides an excellent air-conditioning effect).

In addition, the operation control device allows you to operate only the air conditioner,
Since the air conditioner and the blower (air blower) can be selectively operated in parallel, control with excellent operability can be achieved.

Furthermore, when the air conditioner and the blower (air blower) are operated in parallel, the room temperature setting value of the air conditioner automatically slides, thereby preventing discomfort and wasteful power consumption due to excessive cooling.

In addition, when the air conditioner and the blower (air blower) are in parallel operation mode, if the blower (air blower) is not operating, the room temperature setting value will not slide, causing the room temperature to rise and cause discomfort. Never.
