[Industrial application field]

The present invention relates to a blower using a ceiling fan or the like for home or business use.

【0002】

[Conventional technology]

In recent years, the indoor thermal environment is required to be more comfortable, and in the convection heating and cooling system, the temperature difference between the upper and lower sides of the room has become a problem as an unpleasant factor.

【0003】

In order to deal with this problem, convection cooling has been considerably improved by changing the wind direction, but on the other hand, the wind itself for improvement becomes an unpleasant factor during heating, and the temperature difference between the upper and lower sides of the air conditioner alone. There is a limit to how small it can be. Therefore, it has been attempted to make the temperature distribution in the room uniform by using a ceiling fan or the like in combination and rotating the blades in the reverse direction. Here, the reason why the blades are rotated in the reverse direction is to forcibly send the cold air on the lower side to the ceiling side and push down the warm air staying on the upper part so that the air can be agitated efficiently.

[Problems to be Solved by the Invention]

However, such a ceiling fan is operated manually by a person, and if you forget to operate it during heating, it will be an unpleasant indoor environment with a difference in temperature between the top and bottom, so you have to raise the set temperature because your feet are cold. The operation situation is contrary to energy saving. Also, if you are operating during heating and then stop heating, if you forget to stop the ceiling fan, you will naturally waste energy. Further, in the case of continuous operation, the operation is performed more than necessary for the purpose of improving the temperature difference between the upper and lower sides, resulting in unnecessary operation. As described above, there is a problem that the temperature distribution in the room cannot be made uniform efficiently and the efficiency is poor in terms of energy consumption.

【0005】

An object of the present invention is to provide a blower device in which the temperature distribution in a room can be efficiently made uniform and the efficiency is improved in terms of energy consumption in consideration of the conventional problems.

[Means for solving problems]

According to the present invention, a ventilation means provided in a room, a first room temperature detecting means for detecting the room temperature in the upper part of the room, a second room temperature detecting means for detecting the room temperature below the upper part of the room, and the first room temperature detecting means thereof. A blower device including a room temperature comparison means for comparing the room temperature detected by the second room temperature detecting means, and a control means for changing the operating state of the blower means according to the comparison result.

【0007】

[Action]

In the present invention, the first room temperature detecting means detects the room temperature in the upper part of the room, the second room temperature detecting means detects the room temperature below the upper part of the room, and the room temperature comparing means compares the detected room temperatures and compares them. Depending on the result, the control means changes the operating state of the blower means.

【0008】

[Example]

Hereinafter, the present invention will be described with reference to the drawings showing examples thereof.

【0009】

FIG. 1 is a configuration diagram of a blower using a ceiling fan according to an embodiment of the present invention. That is, a blower using a ceiling fan 1 and an air conditioner 5 for heating and cooling are provided in the room. The blower includes a ceiling fan 1 attached to the center of the ceiling in the room, a control device 2 for controlling the operation stop of the ceiling fan 1, a room temperature detecting means 3 for detecting the room temperature in the lower part of the room, and the vicinity of the ceiling. The upper room temperature detecting means 4 for detecting the room temperature of the air conditioner, the room temperature comparing means 7 for comparing the room temperatures detected by the room temperature detecting means 3 and the upper room temperature detecting means 4, and the control device for a signal indicating the operating state of the air conditioner 5. It is composed of a control signal line 6 to be sent to 2. Here, the room temperature comparison means 7 outputs the room temperature comparison result to the control device 2. Further, the room temperature in the lower part of the room may be detected by using the room temperature detecting means 3'built in the air conditioner 5 instead of the room temperature detecting means 3 (the connection in that case is indicated by a chain line).

【0010】

FIG. 2 is a flowchart showing an example of the processing flow of the control device 2 of the above embodiment.

【0011】

Next, the operation of the above embodiment will be described with reference to FIG.

【0012】

First, when the air conditioner 5 is heated and the operation is started, the heating operation signal is sent to the control device 2 through the control signal line 6. At the same time, the room temperature data (Td) detected by the room temperature detecting means 3'(here, an example in which the room temperature detecting means 3'built in the air conditioner 5 is used without using the room temperature detecting means 3 installed separately). Is input to the room temperature comparison means 7.

【0013】

Next, the control device 2 determines whether it is in the heating mode or the cooling mode (step S1), and if it is in the heating mode as a result, sends a measurement start signal to the upper room temperature detecting means 4 (step S2), and then the room temperature comparing means 7 sends a measurement start signal. Receive the upper room temperature data (Tu) (step S3). The room temperature comparison means 7 compares the two received room temperatures (step S4), and outputs the comparison result to the control device 2. If the comparison result (Tu-Td) is 2 or less, the controller 2 sends a stop signal to the ceiling fan 1 (step S7) (however, the ceiling fan 1 is not operating now, so it remains stopped). ..

【0014】

In this way, the measurement and reception of the room temperature data (Td) and the upper room temperature data (Tu) are repeated until the comparison result (Tu-Td) exceeds 2. When the comparison result (Tu-Td) exceeds 2, the control device 2 transmits a reverse rotation operation signal to the ceiling fan 1 (step S5). Once the ceiling fan 1 starts operation and operates for a certain period of time, the measurement and reception of room temperature data (Td) and upper room temperature data (Tu) are started, and the comparison result (Tu-Td) of the control device 2 becomes 2 or less. The ceiling fan 1 is operated as it is until it becomes, and when the comparison result (Tu-Td) becomes 2 or less, a stop signal is sent to the ceiling fan 1 (step S7) to stop the ceiling fan 1.

【0015】

After that, when the heating operation of the air conditioner 5 is stopped, the control device 2 receives the stop signal of the air conditioner 5 via the control signal line 6. At this time, if the comparison result (Tu-Td) is 2 or less, the above processing is terminated, and if the comparison result (Tu-Td) exceeds 2, a stop signal is sent to the ceiling fan 1 after it becomes 2 or less. Make a call and end the above process.

【0016】

On the other hand, when the air conditioner 5 is cooled and the cooling operation signal is input to the control device 2 via the control signal line 6, the cooling mode is processed (step S8), and the control device 2 goes to the ceiling fan 1. Sends a forward rotation operation signal. Here, the reason why the ceiling fan 1 is rotated in the forward direction during cooling is that the temperature difference between the upper and lower sides is generally small during cooling and the wind gives comfort.

【0017】

As described above, by controlling the operation of the ceiling fan 1 according to the detected vertical temperature difference in the room, the ceiling fan 1 can be efficiently automatically operated and energy saving can be achieved so that the vertical temperature distribution is not formed in the room. ..

【0018】

Furthermore, by receiving the operation signal during cooling or heating of the air conditioner 5, the ceiling fan 1 is efficiently automatically operated, causing discomfort due to the temperature difference between the upper and lower parts of the room due to forgetting to operate, and forgetting to stop. Waste of energy is eliminated, and a comfortable indoor thermal environment can be created simply by turning the air conditioner on and off.

【0019】

In the above embodiment, the upper room temperature detecting means 4 which is the first room temperature detecting means is arranged near the ceiling, but the present invention is not limited to this, and any other place as long as the room temperature can be detected in a place where the room temperature is high. There may be. Further, the room temperature detecting means 3'or 3, which is the second room temperature detecting means, is not limited to the arrangement location as long as it is below the first room temperature detecting means. Required upper and lower temperature difference in the room may be put them at room temperature detecting means so as to detect the.

【0020】

Further, in the above embodiment, the control device 2 which is a control means is configured to operate / stop the ceiling fan 1 according to the comparison result of the room temperature only at the time of heating, but the present invention is not limited to this and also at the time of cooling. Similarly, it may be configured to start and stop. In that case, the rotation direction of the ceiling fan 1 may remain forward.

【0021】

Further, in the above embodiment, the ceiling fan 1 which is a blowing means is controlled by operating / stopping according to the comparison result of the room temperature, but the present invention is not limited to this, and is continuous or stepwise depending on the comparison result of the room temperature. The ventilation capacity may be changed by changing the number of rotations.

【0022】

Further, in the above embodiment, the ventilation means is arranged on the ceiling, but the present invention is not limited to this, and of course, it may be arranged in another place as long as the temperature distribution in the room can be made uniform.

【0023】

Further, in the above embodiment, the operation signal is directly input from the air conditioner 5 by using the control signal line 6 as the operation state detection means of the air conditioner 5, but the operation state of the air conditioner 5 is not limited to this. If it can be detected, for example, it may be configured by detecting whether the change in room temperature is upward or downward to detect the state of cooling or heating operation.

【0024】

Further, in the above embodiment, the control device 2 and the room temperature comparison means 7 are configured by dedicated hardware, but the same functions may be configured by software using a computer.

【0025】
