Abstract

PURPOSE:To obtain circulation wind similar to natural wind by disposing a plurality of circulators in which a direction of reverse wind is altered by switching an electric circuit at positions sufficiently separated from each other in a room, and combining controllers for controlling to form not only wind of one direction but also the reverse wind at a suitable time. CONSTITUTION:A motor 3 is supported by motor support members 4A, 4B in cylindrical cases 2A, 2B. A fan 5 is coupled directly to a motor shaft. An upper cover 6, a controller 7 and a remote control signal transceiver 8 are disposed. The cases 2A, 2B are formed in a structure which can be rotated to a support base, and rotating direction and angle are controlled by an auxiliary motor 13. Not only wind of one direction but also reverse wind can be formed, and wind P of a solid line and wind Q of a broken line are formed at a suitable time. A stream line of a predetermined direction can be switched to that of a reverse action. The winds P and Q have variations in a time base manner. An operation can be simplified and finely controlled by reading indoor conditions such as a temperature distribution, etc., and automatically operating an apparatus.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circulation device for effectively circulating room air.

[0002]

2. Description of the Related Art Circulators are usually used to move air in a room to eliminate uneven temperature distribution or to obtain coolness due to wind. Air conditioners are extremely important for improving habitability, but air conditioners alone are not as comfortable as the natural wind outside. This is because the wind does not change even if it simply circulates in one direction. In addition, there was a circulation device that was combined with a conventional air conditioner,
Even if there was an effect of eliminating the temperature difference due to wind in only one direction, we could not obtain the sensation effect of changing wind. A conventional fan can change the blowing direction, but even if multiple fans are used, the blowing directions are not related and a smooth circulating flow does not occur in the room.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to provide a circulation device which can be obtained with a feeling close to that of natural wind.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a plurality of circulation devices, each of which has a blowing direction that can be changed by switching an electric circuit, are arranged in a room at positions sufficiently separated from each other, so that not only one direction air flow The circulation device is a combination of controllers for controlling the opposite wind to be formed at appropriate times.

[0005]

Function: Not only one direction wind but also the opposite direction wind can be formed and the signal is controlled so as to change with respect to the time axis.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an arrangement example of the circulation devices 1 and 2, and FIG. 2 shows an exploded perspective view. The motor 3 is supported by the motor support members 4A and 4B in the cylindrical cases 2A and 2B. The fan 5 is directly connected to the motor shaft. Reference numeral 6 denotes an upper cover on which a control unit 7 and a remote control signal transmission / reception unit 8 are arranged. The wind direction plate 9, the purification filter 10, and the rear cover 11 are assembled to the cylindrical cases 2A and 2B. Reference numeral 12 is a support base, and the cylindrical cases 2A and 2B are structured so as to be rotatable with respect to the support base. The rotation direction and angle are controlled by the auxiliary motor 13. FIG. 3 shows a plan view of an example of installation of the circulation devices 1 and 13.
Indicates an air conditioner. In the circulation device of the present invention, not only one direction wind but also the opposite direction wind can be formed, and the solid line wind P and the broken line wind Q are formed at appropriate times. It can also be expressed as switching from a streamline in a certain direction to a streamline with an opposite action.

4 and 5 show examples of control. The horizontal direction means the change of the time axis, and the vertical directions (P) (Q) mean the solid line wind P and the broken line wind Q, respectively. The lengths of (P) and (Q) are changed along the time axis. FIG. 5 shows an example in which changes in (P) and (Q) are gentler than in FIG. The rhythm is cool in the airflow changes in the summer and cold in the winter, so it is desirable to be fast in the summer and slow in the winter.

In FIG. 6, even if the air volume is the same (P), there are two levels of strong and weak changes.

FIG. 7 shows an example in which changes in the number of revolutions are not stepwise but are connected by gentle changes. The change in the number of revolutions is related to the change in the air volume, and by causing such a change, it is possible to control the air flow in the room more closely to the change in the wind caused by the natural wind outside.
Regarding the length of (P) (Q), the change in air volume, and the rhythm of (P) (Q) switching, a method of putting it in a pattern in the memory of the microprocessor and taking it out with the selection button,
Alternatively, it is possible to read the indoor condition with a sensor and give an appropriate change from the indoor condition. The indoor conditions may include indoor and outdoor temperatures, temperature differences, and the degree of air pollution. There are many patterns to avoid monotonous rhythm, but it is also effective to use random number table change as a rhythm forming factor.

FIG. 8 shows a specific example of the motor 3 control circuit.
Reference numeral 10 indicates a bidirectional control element. The speed of the motor can be adjusted by controlling the signal between b and c. The remote control signal transmission / reception unit 8 can be wirelessly controlled by an infrared light signal.
The optical signal is coded exclusively for the device to prevent accidental movement of other devices. Even if the two circulation devices 1 and 2 are installed in a diagonal corner of a room or the like, it is possible to smoothly circulate the air without causing mutual blows of air.

By reading the indoor condition such as the temperature distribution by the sensor and automatically operating the device, the operation can be simplified and finely controlled. Further, by linking with the control of the air conditioner, more comfortable control of the occupants can be achieved.

Although one set of installation examples has been described for the sake of simplicity, a plurality of sets may be provided if the indoor air is controlled in a timely manner so that the user can feel the air in a manner close to the natural shape. I don't care. A plurality of installations can be considered depending on the size of the room and the shape of the room such as an L shape. Although it is described as an example of floor installation, it is not limited to this in consideration of the effective circulation of the entire room, and it has flexibility including the positional vertical relationship such as floor and wall. Although an example of controlling a plurality of units by controlling the remote controller has been described, it is also possible to provide a schedule control function to each circulation device to obtain smooth circulation.

The change in the blowing direction is not limited to the method of moving the main body, but can be achieved by moving the wind direction plate. Further, the type of fan and the shape of the main body of the circulation device are not limited to the through-flow fan type of the illustrated example, and may be an axial flow type or the like.

INDUSTRIAL APPLICABILITY According to the present invention, the blowing direction can be changed by switching the electric circuit, so that not only the wind in one direction but also the wind in the opposite direction,
In addition, by operating multiple circulation devices that are combined with a controller that controls them so that they can be formed in a timely manner by changing them with respect to the time axis, by operating them by arranging them in positions that are sufficiently separated You can get a feeling similar to the natural breeze, which gives you a feeling of comfort that is not possible with. Regarding the change pattern of signal control, the user can select the operation contents by selecting the button. In addition, indoor conditions, that is, indoor and outdoor temperature, temperature difference,
The change can be selected according to the number of people and the degree of air pollution.
