Description

  The present invention relates to a ceiling fan provided with a human detection unit.

  Conventionally, this type of ceiling fan is known to save energy by detecting the presence or absence of a person in the air blowing target range by a human detection unit and controlling the operation of the motor in accordance with the detection state. (For example, refer to Patent Document 1).

JP 2010-138865 A

  In a ceiling fan having such a human detection unit, conventionally, when a human is detected by the human detection unit, the motor is operated, and when no human is detected, the motor operation is stopped after a certain period of time. Had reduced. However, in this method, it is conceivable that the accuracy is low because of the presence / absence of the person only by the person detection unit, and the operation is not desired by the user. That is, it is conceivable that the operation is stopped despite the presence of a person, and the operation and the stop are repeated unnecessarily when the person goes in and out of the room.

  Therefore, an object of the present invention is to provide a ceiling fan that can perform more appropriate operation while reducing power consumption.

  In order to achieve this object, the ceiling fan according to the present invention includes a support column that can be engaged with the ceiling, a motor that rotates around the support column, and a blade that blows air based on the rotation of the motor. A lighting unit that can be switched on / off based on a human operation, a human detection unit that detects the presence or absence of a surrounding person, a lighting state of the lighting unit, and a detection state of the human detection unit And an operation control unit that controls the operation of the motor based on the combination, thereby achieving the intended purpose.

  According to the ceiling fan according to the present invention, when the operation of the motor is determined, in addition to the detection state of the human detection unit, more appropriate operation is performed by considering the lighting state of the illumination that the user operates with intention. The effect that it is possible can be acquired.

The perspective view which shows the structure of the ceiling fan which concerns on Embodiment 1 of this invention. The block diagram which shows the structure of the ceiling fan which concerns on Embodiment 1 of this invention. State transition diagram showing control contents of ceiling fan according to Embodiment 1 of the present invention

  The ceiling fan according to the present invention is lit on the basis of a human operation, a support column that can be engaged with the ceiling, a motor that rotates around the support column, a blade that blows air based on the rotation of the motor, and the like. Control of operation of the motor based on a combination of a lighting unit that can be switched on / off, a human detection unit that detects the presence or absence of a surrounding person, and a lighting state of the lighting unit and a detection state of the human detection unit And an operation control unit.

  This makes it possible to operate the motor based on a more accurate understanding of the situation by taking into account the lighting state of the user's intentional operation in addition to the detection state of the human detection unit when determining the motor operation. Thus, it is possible to obtain an effect that more appropriate driving can be performed.

  The operation control unit includes a transition detection unit that detects a transition of a state in which a detection state of the human detection unit and a lighting state of the illumination unit are combined, a detection state of the human detection unit before the transition, and the illumination unit A state storage unit that stores a lighting state of the state, a state determination unit that determines a detection state of the human detection unit and a lighting state of the illumination unit after the transition, and a transition of the state detected by the transition detection unit And the detection state of the human detection unit before the transition stored in the state storage unit before transition and the lighting state of the illumination unit before the transition, and the human detection unit after the transition determined by the state determination unit And a motor control unit that controls the operation of the motor based on the detected state and the lighting state of the illumination unit after the transition.

  Thereby, when the transition detection unit detects the transition of the state, the operation control unit not only includes the state after the transition determined by the state determination unit but also the state before the transition stored in the state storage unit before transition. By determining the operation by the motor control unit based on the combination of the above, it is possible to change the operation in accordance with the change contents of the state, and it is possible to obtain an effect that more appropriate operation can be performed.

  In addition, when the state after the transition determined by the state determination unit is “lighting” and the detection state is “non-detection”, the motor control unit stores the state in the pre-transition state storage unit. It is also possible to employ a configuration in which at least one of the pre-transition state patterns is controlled differently from the transition from another pattern state.

  Thereby, when the lighting state is “lighting” and the detection state is “non-detection”, the motor control unit controls the operation of the motor according to the state stored in the pre-transition state storage unit, It is possible to perform an operation more suitable for the situation, and to obtain an effect that a more appropriate operation can be performed.

  In addition, the motor control unit is a case where the state after the transition is a case where the lighting state is “lighting” and the detection state is “non-detection”, and the pattern of the state before the transition is “lighting off and detection”. Or, in the case of “lit and detected”, the motor operation is stopped after a lapse of a predetermined time, and when the state pattern before the transition is “extinguished and not detected”, the motor operation before the transition is continued. It is good.

  As a result, when the lighting state is “lighting” and the detection state is “non-detection”, depending on the change in the state, there is no person being detected, When the person is not detected, the driving content can be changed, and an effect that more appropriate driving can be performed can be obtained.

  Further, the motor control unit is the case where the state after the transition determined by the state determination unit is the case where the lighting state is “off” and the detection state is “detection”, and is stored in the pre-transition state storage unit It is good also as a structure which performs control different from the case where it changes from the state of another pattern by the at least 1 pattern among the patterns of the state before the transition currently performed.

  Thereby, when the lighting state is “off” and the detection state is “detection”, the motor control unit controls the motor operation according to the state stored in the pre-transition state storage unit, It is possible to perform driving that suits the situation, and to obtain an effect that more appropriate driving can be performed.

  Further, the operation control unit includes a transition detection unit that detects a transition of a state in which a detection state of the human detection unit and a lighting state of the illumination unit are combined, a detection state of the human detection unit after the transition, and the illumination unit A state determination unit for determining the lighting state of the state, a transition of the state detected by the transition detection unit, a detection state of the human detection unit after the transition determined by the state determination unit, and the illumination unit after the transition It is good also as a structure provided with the motor control part which controls the driving | operation of the said motor based on the lighting state.

  Thereby, when the transition detection unit detects a transition of the state, the operation control unit determines the operation by the motor control unit based on the state after the transition determined by the state determination unit, and thereby responds to the current state. The effect that it can perform the more suitable driving | operation can be obtained.

  In the motor control unit, the state after the transition detection unit detects the state transition is a case where the lighting state is “lighting” and the detection state is “detection”, and the motor is in operation. It is good also as a structure which continues driving | running when it is, and starts driving | running | working when the said motor has stopped.

  This allows the motor controller to start or continue the motor operation when the lighting state is “lit” and the detection state is “detection”. In addition, it is possible to operate the motor and to obtain an effect that more appropriate operation can be performed.

  In addition, the motor control unit may be configured such that the state after the transition detection unit detects the state transition is a case where the lighting state is “off” and the detection state is “non-detection”. If it is in the middle, the motor operation may be stopped after a predetermined time has elapsed.

  As a result, when the lighting state is “off” and the detection state is “non-detection”, the motor control unit stops driving the motor after a predetermined time, thereby reducing the possibility that there is a person. Then, while stopping the operation of the motor, it is possible to prevent the motor from frequently repeating the operation and the stop due to the change of the state, and it is possible to obtain an effect that more appropriate operation can be performed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The following embodiments are examples embodying the present invention, and do not limit the technical scope of the present invention. In addition, throughout the drawings, the same portions are denoted by the same reference numerals, and the second and subsequent descriptions are omitted. Furthermore, in each drawing, the description of the details of each part not directly related to the present invention is omitted.

(Embodiment 1)
The structure of the ceiling fan body 1 according to the present embodiment will be described with reference to FIG. FIG. 1 is a perspective view showing the configuration of the ceiling fan according to the first embodiment.

  The ceiling fan main body 1 can be engaged with the ceiling by the support column 2, and is installed on the ceiling of the living room, for example, and can blow air into the living room. The ceiling fan main body 1 blows air by rotating the blade portion 4 by a motor 3 that rotates around the support column portion 2 as an axis. The person detection unit 5 detects the presence or absence of a surrounding person, and the ceiling fan body 1 controls air blowing based on the detection / non-detection of the person detected by the person detection unit 5.

  Conventionally, in such a ceiling fan, it is known to save energy by blowing air when a person is detected by the person detection unit 5 and stopping blowing after a certain time when no person is detected. ing. However, in this method, since the presence / absence of the person is determined only by the person detection unit 5, it is considered that the situation determination accuracy is low and the operation is not desired by the user.

  Therefore, in the first embodiment, the ceiling fan main body 1 controls the air blowing based on the combination with the lighting state of the lighting unit 6 as well as the detection state of the human detection unit 5. The illumination unit 6 is used as illumination in a living room and can be switched on / off by a user operation. Thereby, when the operation of the motor 3 is determined, in addition to the detection state of the human detection unit 5, the situation can be determined including the lighting state of the illumination unit 6 that the user operates with an intention. The motor 3 can be operated based on the grasp of the situation.

  Next, operation | movement of the ceiling fan main body 1 is demonstrated using FIG. FIG. 2 is a block diagram showing the configuration of the ceiling fan according to the first embodiment.

  The ceiling fan main body 1 includes an operation control unit 7 that controls the operation of the motor 3 based on the combination of the detection state of the human detection unit 5 and the lighting state of the illumination unit 6. Hereinafter, the configuration of the operation control unit 7 will be described.

  The operation control unit 7 includes a state determination unit 8, a transition detection unit 9, a pre-transition state storage unit 10, and a motor control unit 11.

  The state determination unit 8 is in any one of four state patterns that combine the two states of detection / non-detection of the human detection unit 5 and the two states of lighting / extinguishing of the illumination unit 6. Determine whether. That is, it is determined whether the state is S0 “lighting and not detected”, S1 “lighting and not detected”, S2 “lighting and detected”, or S3 “lighted and detected”. Hereinafter, unless otherwise specified in the present embodiment, the “state” is any one of patterns of four states in which the detection state of the human detection unit 5 and the lighting state of the illumination unit 6 are combined. Indicates a state. The state S0 means “lighting and not detected”, the state S1 means “lights off and not detected”, the state S2 means “lights off and detected”, and the state S3 means “lights and not detected”. It means “detection”.

  The transition detection unit 9 detects the state transition based on the detection state of the human detection unit 5 and / or the change in the lighting state of the illumination unit 6 or both.

  The pre-transition state storage unit 10 stores a state in advance so that when the transition detection unit 9 detects a state transition, the state before the transition can be referred to.

  The transition detection unit 9 detects input from the human detection unit 5 and the illumination unit 6 at any time to detect a state transition, and the state determination unit 8 redetermines the state at the timing when the transition detection unit 9 detects the transition. To do.

  When the state transition occurs, the pre-transition state storage unit 10 holds the original storage state until the operation of the motor 3 is determined in the operation control unit 7. Therefore, when the transition detection unit 9 detects a transition, the pre-transition state storage unit 10 stores the state before the transition, and the state determination unit 8 recognizes the state after the transition.

  When the state transition is detected by the transition detection unit 9, the motor control unit 11 stores the state before the transition stored in the pre-transition state storage unit 10 and the state after the transition recognized by the state determination unit 8. Based on the state, the operation of the motor 3 is selected and determined. In the first embodiment, there are four types of operations of the motor 3 determined by the motor control unit 11: “ON”, “continuation of operation”, “delay (short)”, and “delay (long)”.

  When “ON” is selected by the motor control unit 11, the operation of the motor 3 is started. Continue driving if you are already driving. When “continuation of operation” is selected, the operation state immediately before the motor 3 is continued. When “delay (short)” is selected, the motor 3 is operated for a predetermined time and then stopped. When “delay (long)” is selected, the motor 3 is operated for a predetermined time longer than the “delay (short)” time, and then stopped.

  The operation of “delay” is to continue driving for a predetermined time after the detection state of the human detection unit 5 becomes “non-detection”. This is provided to prevent the operation from being stopped or started each time a person frequently leaves or enters the room.

  In the first embodiment, when the detection state becomes “non-detection”, when the lighting state of the illumination unit 6 is “lighting” compared to the case where the lighting state is “lighting off”, the person is within a predetermined time. The delay time is long because the possibility of returning to the room is high. After the operation of the motor 3 is determined by the motor control unit 11, the storage content of the pre-transition state storage unit 10 is overwritten with the state recognized by the state determination unit 8.

  Hereinafter, a specific operation example of the ceiling fan body 1 will be described with reference to FIG. FIG. 3 is a state transition diagram showing the contents of control by the motor control unit 11 of the ceiling fan according to the first embodiment. In the state determination unit 8 and the pre-transition state storage unit 10, the state of S0 “lights off and not detected” is set as the initial state.

  When the ceiling fan main body 1 is turned on in the room where the ceiling fan main body 1 is installed, the human detection unit 5 starts to acquire a detection signal by the sensor, and the illumination unit 6 is turned on or off in accordance with a user operation. Turns off.

  From the initial state, for example, when the lighting unit 6 is in the “lighting state”, the transition detection unit 9 detects that there has been a state transition, and the state determination unit 8 determines that the state after the transition is S1 “lighting and non-detection” Is determined.

  Here, the motor control unit 11 determines the operation of the motor 3 based on the state S0 stored in the pre-transition state storage unit 10 and the state S1 determined by the state determination unit 8. That is, based on FIG. 3, A1 “continuation of operation” which is a motor operation at the time of transition from the state S0 to the state S1 is selected. The motor control unit 11 can change the operation of the motor 3 according to the content of the state transition by operating the motor 3 according to the operation content selected and determined.

  In this example, since the motor 3 is stopped before the state transition, the operation of the motor 3 continues to be stopped by selecting A1 “continuation of operation”.

  Next, when the detection state of the human detection unit 5 becomes “detection” from this state, the motor control unit 11 selects the motor operation A10 in the state change from the state S1 to the state S3 in the same flow. The operation of 3 is “ON”.

  After this, when the detection state of the human detection unit 5 becomes “non-detection” again, the motor control unit 11 similarly selects the motor operation A9 in the state change from the state S3 to the state S1. The operation of No. 3 is “delay (long)”. As a result, the motor 3 stops after operating for a predetermined time.

  Here, when the state after the transition determined by the state determination unit 8 is S1 “lighting and non-detection”, at least one pattern among the patterns of the state before the transition stored in the state storage unit 10 before the transition Therefore, the control is different from the case of transition from the state of another pattern. That is, when attention is paid to the transition to the state S1, the operation is “continuation” at the transition from the state S0, and the “delay (long)” is at the transition from the state S2 or the state S3.

  That is, in the case of the transition from the state S0 to the state S1, it is considered that the necessity of starting the operation of the motor 3 at that time is low because of a change in illumination in a state where no human is detected.

  On the other hand, since the transition from the state S2 or the state S3 is a transition when the state of detecting a person is not detected, the operation of stopping after delaying the motor 3 that has already been operated is performed. It is considered appropriate.

  As described above, even when transitioning to the same state, the appropriate operation of the motor 3 may differ depending on the state before the transition. According to the configuration of the ceiling fan main body 1 according to the first embodiment, the operation of the motor 3 can be changed depending on the state before the transition, even in the transition to the same state. I can drive.

  In addition, even when the state after the transition determined by the state determination unit 8 is S2 “extinguish and detect”, at least one pattern of the state before transition stored in the state storage unit 10 before transition The control is different from the case of transition from other pattern states. That is, “ON” is selected at the transition from the state S0 or the state S1 to the state S2, and “continuation of operation” or “delay (long)” is selected at the transition from the state S3 to the state S2. The transition from the state S3 to the state S2 corresponds to a case where the lighting changes from lighting to off in a state where a person is detected, such as a case where the user turns off the lighting during sleep. In this case, whether it is appropriate to continue or stop driving during sleep depends on the user's preference, and by setting the operation when this condition is met with a remote control etc. in advance, the desired operation It can be performed.

  In FIG. 3, the operation at the time of transition to the state S0 is the same regardless of the state before the transition. That is, in the operation control unit 7, when the transition detection unit 9 detects the state transition, the motor control unit 11 determines the state according to the state determined by the state determination unit 8. Since the state S0 is a “light-off and non-detection” state, and it is highly likely that the person is not in the room and will not return for a while, the state S0 is “delay ( Short) ", and the motor 3 stops after a predetermined time of operation. The operation at the time of transition to the state S3 is the same regardless of the state before the transition. Since the state S3 is a “lighting and detection” state and there is a high possibility that a person remains in the room, “ON” is selected, and the motor 3 starts or continues operation.

  As described above, when determining the operation of the motor 3, the motor control unit 11 does not necessarily use the state stored in the pre-transition state storage unit 10 depending on the state after the transition. In other words, when only such a case is mounted on the ceiling fan body 1, the pre-transition state storage unit 10 is not necessarily required.

  However, as described above, by determining the operation of the motor 3 according to the pre-transition state stored in the pre-transition state storage unit 10 and the post-transition state recognized by the state determination unit 8 as necessary, It is possible to grasp more various situations and operate the motor 3 according to the situations.

  The ceiling fan according to the present invention determines the operation of the motor based on the state before the transition and the state after the transition at the time of the state transition of the detection state of the human detection unit and the lighting state of the illumination unit, It is useful as a ceiling fan having an illumination part.
