The blower 10 is capable of adjusting the wind speed by adjusting the output of the blower motor 54a under the control of the control board 26.

<< Operation of blower 10 >>
Subsequently, the operation peculiar to the blower 10 will be described. The blower 10 can be operated by performing an operation of inputting operating conditions via the operation unit 60 or the remote controller 62. Specifically, the blower 10 inputs operating conditions such as start and stop of the blower operation, setting of the wind speed, start and stop of swinging in the left-right direction and swinging in the up-down direction via the operation unit 60 and the like. can do. The blower 10 controls the operation of the blower motor 54a, the left / right swing motor 22, the vertical swing motor, and the like based on the output signal output from the control board 26 in response to the input from the operation unit 60 and the like. In this way, the blower 10 can operate according to the input conditions input via the operation unit 60 and the like.

Here, the blower 10 can operate in a specific operation mode defined in advance in addition to the basic operation as described above. Specifically, the blower 10 has a continuous mode in which the wind is continuously blown at a constant wind speed selected by the user, a rhythm mode in which the wind is blown while switching the strength of the wind speed, and further, for example, under conditions suitable for sleeping. As an operation mode for performing operation, an operation mode called a good night mode is defined. In the good night mode, the direct wind that hits the sleeping person is weakened, and the wind is blown at a higher wind speed than the direct wind in the direction that does not hit the sleeping person directly, and the convection operation is assumed to form a convection wind in the room. It is an operation mode in which the above is performed, and may be paraphrased as a convection wind mode.

When the good night mode is selected, the blower 10 operates the up / down swing motor 40 to move the blower direction into the blower region over a predetermined angle range in the vertical direction from an angle in which the blower direction is tilted downward to an upward angle. The air is blown while changing the posture of the air blower 50 so as to reciprocate with. Specifically, in the present embodiment, the blasting unit reciprocates within a blasting range of approximately 115 degrees in the vertical direction from an angle in which the blasting region is tilted downward by approximately 15 degrees to an angle of approximately 90 degrees in the upward direction. Blow while changing the posture of 50.

Here, as shown in FIG. 3 and the like, among the above-mentioned vertical ventilation regions, the first vertical ventilation region is the ventilation region extending from an angle range of approximately 15 degrees downward (approximately -15 degrees) to approximately 15 degrees upward. UD1, the blowing region above the first vertical blowing region UD1 and extending over an angle range of approximately 90 degrees upward from a predetermined upward angle θ1, is the second vertical blowing region UD2, the first vertical blowing region and the second blowing region. The blast region over the angle range between and (a range of more than approximately +15 degrees and less than a predetermined upward angle θ1) is defined as the third vertical blast region UD3. When specified in this way, in the good night mode, the blowing direction changes depending on the path from the first upper and lower blowing area UD1 to the second upper and lower blowing area UD2 via the third upper and lower blowing area UD3 and the path in the opposite direction. The operation of the vertical swing motor 40 is controlled so as to be performed.

Further, in the good night mode, the output of the blower motor 54a is controlled so that the wind speed Y2 (Y2> Y1) in the second upper and lower blower area UD2 is higher than the wind speed Y1 in the first upper and lower blower area UD1. For example, in the good night mode, the output is controlled so that the wind speed Y1 is 1 while the wind speed Y2 is 5, or the wind speed Y1 is 4 while the wind speed Y2 is 8. The output of the blower motor 54a is controlled so that the relationship of wind speed Y2> wind speed Y1 is established, such as by performing control.

Further, when the good night mode is selected, the blower motor 54a is controlled so that the wind speed gradually fluctuates in the third upper and lower blower region UD3. Specifically, when the blower unit 50 swings from the bottom to the top, that is, the blower unit 50 starts from the first upper and lower air blower area UD1 and passes through the third upper and lower air blower area UD3 to the second upper and lower air blower area UD2. When swinging in the path leading to, the blower motor 54a is controlled so that the wind speed Y3 in the third vertical blower region UD3 gradually increases from the wind speed Y1 to the wind speed Y2. On the contrary, when the blower unit 50 swings from the top to the bottom, that is, the blower unit 50 moves from the second upper and lower air blower area UD2 through the third upper and lower air blower area UD3 to the first upper and lower air blower area. When swinging in the path leading to UD1, the blower motor 54a is controlled so that the wind speed Y3 in the third vertical blower region UD3 gradually decreases from the wind speed Y2 to the wind speed Y1.

Further, the blower 10 can set a timer by operating the operation unit 60 or the remote controller 62. Specifically, the blower 10 has an off timer function for stopping the operation after a set time has elapsed, and an on timer function for starting the operation after the set time has elapsed. The blower 10 can intuitively set a complicated timer according to the order in which the off timer function and the on timer function are set.

Specifically, when the timer is set to stop the blast when t1 hour has elapsed from the current time and to restart the blast when t2 hours have passed from the time when the blast is stopped in the state where the blast operation is performed. First sets the off timer to t1 hour, and then sets the on timer to t2 hour. In addition, when the timer is set to start the blast when t3 hours have elapsed from the current time and to stop the blast when t4 hours have passed from the start of the blast in the state where the blast operation is stopped. First, the on timer is set to t3 hours, and then the off timer is set to t4 hours. As described above, the blower 10 can intuitively set a complicated timer by setting the off timer function and the on timer function according to the scheduled operation start and operation stop order.

As described above, the blower 10 of the present embodiment has a blowing direction over a blowing range in the vertical direction including the first upper and lower blowing area UD1, the second upper and lower blowing area UD2 and the third upper and lower blowing area UD3 above the first upper and lower blowing area UD1. Can be blown while fluctuating. As a result, the blower 10 not only forms a direct wind flow toward the user as shown in FIG. 8 (a), but also agitates the air in the room as shown in FIG. 8 (b). Can form a flow of convective wind. By setting the wind speed Y2 (Y2> Y1) in the second upper and lower blast area UD2 higher than the wind speed Y1 in the first upper and lower blast area UD1, the direct wind flow is relatively weakened (reduced) and the convection wind flow is compared. Can be formed strongly. Therefore, according to the blower 10 of the present embodiment, even if it is used at bedtime, a comfortable wind such as a breeze flows through the room while suppressing the problem that the wind keeps hitting and the body gets cold, and the user. You can build an environment where you can spend your time comfortably.

Further, the blower 10 of the present embodiment has a blower motor 54a so that the wind speed fluctuates stepwise or steplessly in the third upper and lower blower region UD3 located between the first upper and lower blower region UD1 and the second upper and lower blower region UD2. Is to be controlled. Therefore, the blower 10 can suppress noise caused by a sudden change in the wind speed between the first upper and lower blower regions UD1 and the second upper and lower blower regions UD2, the generation of entrained wind, and the like.

In the present embodiment, a third upper and lower air blower area UD3 is provided between the first upper and lower air blower area UD1 and the second upper and lower air blower area UD2, and the wind speed Y3 gradually changes in the third upper and lower air blower area UD3. However, the present invention is not limited thereto. For example, the blower 10 may operate so that the wind speed Y3 in the third upper and lower blower region UD3 is constant at an intermediate value between the wind speeds Y1 and Y2. Further, the blower 10 does not have a region corresponding to the third vertical blower region UD3 (in this case, a predetermined upward angle θ1 = approximately 15 degrees upward), and has two regions, a first vertical blower region UD1 and a second vertical blower region UD2. It may consist only of. Further, in the good night mode, it is preferable that the strength can be set in a plurality of stages. For example, if it is weak, the wind speed Y1 in the first upper and lower blast region UD1 is 1, while the wind speed Y2 in the second upper and lower blast region UD2 is 5, and if it is strong, the wind speed Y1 is 4. Output control is performed so that the wind speed Y2 becomes 8. By making it possible to set the strength of the sleep mode, it is possible to respond to changes in the size of the room and the distance from the ventilation target.

It should be noted that, like the blower 10 of the present embodiment, a plurality of areas are defined in the vertical direction, and a area (first vertical blower area UD1) in which a sleeping person is assumed to exist, and other areas. When changing the ventilation conditions in the area (second vertical ventilation area UD2, third vertical ventilation area UD3), the configuration shall be such that the position of the ventilation unit 50 in the vertical direction at the start of operation in the sleep mode can be grasped. Is preferable. As a measure for grasping the position of the blower unit 50, a detection means (specifically, an IR sensor or the like) for detecting the position of the blower unit 50 in the vertical direction may be provided. In addition, the operating conditions for stopping the swinging operation in the vertical direction are satisfied, the operating conditions for stopping the ventilation by pressing the stop button, etc. are satisfied, and the operation for starting the operation in the good night mode is satisfied. The blower unit 50 may be controlled to be returned to the reference position in the vertical direction (reference position in the vertical direction) with the condition that the condition is satisfied as the start condition. The reference position in the vertical direction may be any position, but may be, for example, a predetermined position in the first vertical ventilation region UD1. With such a configuration, the expected effect can be obtained only by the user installing the blower 10 with reference to the reference position. Further, if the configuration is such that the blower returns to the reference position as described above, the blower 10 can be operated by simple operation control on the premise that the operation starts with the reference position as a reference.

Even if the blower unit 50 is returned to the vertical reference position at the timing of the end of operation as described above, the direction of the blower unit 50 is manually switched in the vertical direction, and the air is blown at the start of the next operation. It is assumed that the unit 50 exists at a position deviating from the position recognized on the control board 26 (vertical reference position). Therefore, in such a case, it is desirable that the blower 10 can eliminate the deviation between the position of the blower unit 50 recognized by the control board 26 and the actual position of the blower unit 50. Specifically, it is desirable that the blower 10 performs the operation described below at the start stage of the vertical swing operation.

That is, as shown in FIG. 9, the blower 10 first moves the blower portion 50 up and down by the amount necessary to move the blower portion 50 to the upper limit of the swing range in the vertical direction at the start stage of the swing operation in the vertical direction. The swing motor 40 is operated. Here, if, as shown in FIG. 9A, the blower portion 50 is located above the vertical reference position at the start stage of the swing operation, the blower portion 50 is located at the vertical reference position. The upper limit position of the swing range is reached earlier than when the operation is started from, and the state is stopped (see FIG. 9B). Then, as shown in FIG. 9 (c). The blower 10 moves the blower portion 50 to the lower limit position of the swing range. By performing such an operation, even if there is a deviation between the position of the blower unit 50 recognized on the control board 26 (reference position in the vertical direction) and the actual position of the blower unit 50, the blower unit 50 is the first. The above-mentioned deviation is eliminated by the operation of swinging in the vertical direction.

The blower 10 can eliminate the deviation between the position of the blower unit 50 recognized on the control board 26 (reference position in the vertical direction) and the actual position of the blower unit 50 as described above. It is also possible to eliminate the above-mentioned deviation by, for example, another method as illustrated in FIG. The method illustrated in FIG. 10 will be described in more detail. When the movable range of the blower portion 50 in the vertical direction is the range shown by the arrow in FIG. 10 (a), first, the swinging motion in the vertical direction is performed. At the start stage, as shown in FIG. 10B, as the first step, for swinging up and down so that the blower portion 50 moves in the vertical direction only at a slight angle a1 minute with respect to the allowable range of swing in the vertical direction. Operate the motor 40. After that, as shown in FIG. 10 (c), as the second step, the blower unit 50 started to operate in the vertical direction in the first step in the direction opposite to the swinging in the first step described above. The blower portion 50 is swung by an angle a2 so as to reach the lower side beyond the position. After that, as shown in FIGS. 10 (d) and 10 (e), in the same manner as in the previous step, the direction is opposite to the operation direction in the previous stage, and the blower portion 50 in the previous stage is moved up and down. The operation of swinging the blower portion 50 is repeated for angles a3 and a4 to a position exceeding the swing start position of. Even if there is a discrepancy between the position of the blower unit 50 (reference position in the vertical direction) recognized by the control board 26 and the actual position of the blower unit 50 at the start stage of swinging in the vertical direction, such an operation is performed. As the above steps are repeated, the above-mentioned deviation is eliminated. Eventually, when the swing range of the blower unit 50 reaches the upper limit of the swing allowable range (state in FIG. 10 (e)), the operation for eliminating the above-mentioned deviation is completed. If the above-mentioned deviation is eliminated by such a method, the time lag in which the blower portion 50 does not swing in the vertical direction and is stopped can be minimized in order to eliminate the deviation.

Further, in addition to the above-described configuration, the blower 10 may be provided with an ion generator 70 capable of emitting ozone together with ions. As shown in FIGS. 2 and 7, the ion generator 70 can be arranged, for example, at the lower part of the blower unit 50. The ion generator 70 may be arranged above the blower portion 50, or may be attached to the outside of the blower portion 50. The ions and ozone generated by the ion generator 70 can be diffused by the wind generated in the blower unit 50. When the ion generator 70 is provided, the ion generator 70 is stopped while the blower unit 50 is operating in the first upper and lower blower area UD1 where direct wind is generated, and the second upper and lower blower area where convection wind is generated. It is preferable to operate the ion generator 70 while the blower unit 50 is operating in the UD2 or the third upper and lower blower region UD3.

Further, as shown in FIG. 15, the blower 10 of the present embodiment is in a state where the user is sleeping in cooperation with other devices such as a so-called ceiling light 100, an air conditioner 102, and a smart speaker 104. It may be possible to estimate whether or not the control board 26 or the like is used, and automatically determine whether to operate in the sleep mode or another operation mode based on the estimation result.

Further, as described above, the support column 30 has an outer cylinder portion 32 and an inner cylinder portion 34, and the inner cylinder portion 34 is connected to the left and right swing mechanism portion 24 on the base end side, and the support column 30 is connected. In the middle of the above, it is assumed that the bearing member 36 is provided between the outer cylinder portion 32 and the bearing member 36. Therefore, in the blower 10 of the present embodiment, the stability of the support column 30 is high, and the swinging operation in the left-right direction can be smoothly performed. In the present embodiment, an example in which the support column 30 having the above-described configuration is adopted has been shown, but the present invention is not limited to this, and other configurations may be used.

Further, in the present embodiment, an example in which complicated timer settings can be intuitively performed by setting the off timer function and the on timer function according to the scheduled operation start and operation stop order. As shown, the invention is not limited to this. Specifically, for example, when setting a timer to stop the blast when t1 hours have passed from the present time and restart the blast when t2 hours have passed from the time when the blast has stopped, the off timer is set based on the present time. May be set to t1 hour and the on timer may be set to t1 + t2 hours. Further, the blower 10 may not have the off timer function and the on timer function.

≪First modification example≫
Subsequently, a first modification of the blower 10 shown in the above embodiment will be described. In the following description, the same reference numerals as those shown in the above-described embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

The blower 10 shown in the above embodiment moves the blower unit 50 up and down over the three regions of the first upper and lower blower region UD1, the second upper and lower blower region UD2, and the third upper and lower blower region UD3 while operating in the good night mode. The present invention is not limited to this, although the blowing operation is performed while swinging in the direction and adjusting the wind speed for each region. Specifically, the blower 10 of this modification performs the blowing operation only in the second upper and lower air blowing areas UD2 and the third upper and lower air blowing areas UD3 during the operation in the good night mode, and the first upper and lower air blowing areas UD1. Do not swing or blow air (wind speed Y1 = 0). By doing so, it is possible to generate convection wind that circulates in the room while preventing the wind from directly hitting the sleeping person. Therefore, if the blower 10 of the present embodiment is used at bedtime, it is possible to sleep comfortably while suppressing a decrease in body temperature and fatigue when waking up, which is a concern due to continuous wind hitting the sleeping human body. Can be formed.

In this modification, the wind speeds Y2 and Y3 in both the second upper and lower blast areas UD2 and the third upper and lower blast areas UD3 may be the same or different. Further, in the present modification, the blower 10 blows air so that the wind speed Y3 in the third upper and lower blower region UD3 gradually fluctuates between the wind speeds Y1 and Y2, as in the case of the blower 10 according to the above embodiment. It may control the motor 54a.

Further, it is preferable that the blower 10 of the first modification also has a configuration capable of grasping the position of the blower portion 50 in the vertical direction at the start of operation in the good night mode, similarly to the blower 10 of the above embodiment. As a measure for grasping the position of the blower unit 50, a sensor for detecting the position of the blower unit 50 in the vertical direction may be provided, or a vertical reference position may be provided when the swing operation in the vertical direction is stopped. It is also possible to control the return of the blower unit 50 to. When the blower 10 is configured to control the blower unit 50 to be returned to the reference position in the vertical direction, the expected effect can be obtained only by the user installing the blower 10 with reference to the reference position. Further, if the configuration is such that the blower returns to the reference position as described above, the blower 10 can be operated by simple operation control on the premise that the operation starts with the reference position as a reference.

Further, in the blower 10 of the first modification, the ion generator 70 may be arranged in the vicinity of the blower portion 50, for example.

Further, the blower 10 of the present modification cooperates with other devices such as the so-called ceiling lighting 100, the air conditioner 102, and the smart speaker 104, and determines whether or not the user is in a sleeping state. Etc., and based on the estimation result, it may be automatically determined whether to operate in the sleep mode or another operation mode.

≪Second variant example≫
Subsequently, a second modification of the blower 10 shown in the above embodiment will be described. In the following description, the same reference numerals as those shown in the above-described embodiments and the above-mentioned modifications will be given the same reference numerals, and detailed description thereof will be omitted.

The blower 10 shown in the above embodiment performs the blower operation while swinging in the vertical direction and adjusting the wind speed for each area defined in the vertical direction during the operation in the good night mode. The present invention is not limited to this. Specifically, the blower 10 of this modification is formed in the left-right direction while swinging the blower portion 50 in the left-right direction by operating the left-right swing motor 22 when the sleep mode is selected. The wind speed is adjusted for each area to be blown.

Here, as shown in FIG. 11A, in the above-mentioned left-right direction blowing region, the first left-right blowing is within a range of a predetermined angle θ2 in the left-right direction with respect to the state in which the blowing portion 50 faces the front. The blast area outside the left and right sides of the region LR1 and the first left and right blast regions LR1 is defined as the second left and right blast regions LR2 and LR2. In this case, in the good night mode, after reciprocating the path from the first left / right blast area LR1 to the second left / right blast area LR2 adjacent to one side in the left-right direction and returning to the first left / right blast area LR1. The operation of the left / right swing motor 22 is controlled so that the blowing direction fluctuates in a path reciprocating on the path leading to the second left / right blowing area LR2 on the other side in the left / right direction.

Further, in the good night mode, the output of the blower motor 54a is controlled so that the wind speed X2 (X2> X1) in the second left and right blower area LR2 is higher than the wind speed X1 in the first left and right blower area LR1.

Like the blower 10 of this modification, the blower is blown while changing the blower direction within the blower range extending in the left-right direction including the first left and right blower area LR1 and the second left and right blower area LR2 outside the left and right side. By doing so, the strength of the direct wind that hits the user can be reduced by installing and using the first left and right ventilation area LR1 so as to face the front of the user at bedtime. As a result, it is possible to reduce adverse effects such as coldness of the human body caused by continuous wind hitting the human body while sleeping and fatigue when waking up. Further, according to the blower 10 of the present modification, it is possible to form a convection air flow by blowing air to the second left and right air blow region LR2, and to construct a comfortable environment in which a comfortable wind such as a breeze flows through the room.

In this modification, in the good night mode, an example is shown in which the blower motor 54a is operated so that the wind directly flows at a low wind speed X1 even in the first left and right blower region LR1, but the present invention is limited to this. However, the operation may be performed in a state where the wind speed X1 is substantially zero, such as by stopping the energization of the blower motor 54a in the first left and right blower region LR1.

Further, in the second modification, the ventilation area in the left-right direction is classified into the first left-right air blow area LR1 on the front side and the second left-right air blow area LR2 adjacent to the outside in the left-right direction. Although an example of controlling the wind speed is shown, the present invention is not limited to this. For example, as shown in FIG. 11B, the first left and right air blower areas LR1 and the second left and right air blower areas are similarly classified into three in the vertical direction in the blower 10 shown in the above embodiment. A third left and right blower region LR3 may be provided between the LR2 and the blower motor 54a so that the wind speed X3 gradually fluctuates in the third left and right blower region LR3. Further, from the first lateral blowing region LR1, when you have made swing in a path leading to the second lateral blowing area LR2, gradually wind speed X 3 in the third lateral blowing area LR3 is towards the wind X1 to wind X2 wind Is controlled so that It may be controlled so that the wind speed gradually decreases toward X1.

It should be noted that, as in the blower 10 of the second modification, a plurality of areas are defined in the left-right direction, and a area (first left-right blower area LR1) in which a sleeping person is assumed to exist and a region thereof. When the ventilation conditions are changed in a region other than the region (second left and right ventilation region LR2), it is preferable to have a configuration in which the ventilation unit 50 at the start of operation in the sleep mode can be grasped. As a measure for grasping the position of the blower unit 50, a sensor for detecting the position of the blower unit 50 may be provided. By providing a sensor for detecting the position of the blower unit 50, the center position (reference position) of the blower unit 50 can be corrected even when the blower unit 50 is forcibly moved or stopped. In addition, the operating conditions for stopping the swinging operation in the left-right direction are satisfied, the operating conditions for stopping the ventilation by pressing the stop button, etc. are satisfied, and the operation is started in the good night mode. The blower unit 50 may be controlled to be returned to the reference position in the left-right direction (reference position in the left-right direction) with the condition that the condition is satisfied as the start condition. The reference position in the left-right direction may be any position, but may be, for example, substantially the center of an angle range capable of swinging in the left-right direction. When the blower 10 is configured to control the blower portion 50 to be returned to the reference position in the left-right direction, the expected effect can be obtained only by the user installing the blower 10 with reference to the reference position. Further, if the configuration is such that the blower returns to the reference position as described above, the blower 10 can be operated by simple operation control on the premise that the operation starts with the reference position as a reference.

Further, in the blower 10 of the second modification, the ion generator 70 may be arranged in the vicinity of the blower portion 50, for example. When the ion generator 70 is provided, the ion generator 70 is stopped while the blower unit 50 is operating in the first left and right blower region LR1 where direct wind is generated, and the second left and right where convection wind is generated. It is preferable to operate the ion generator 70 while the blower unit 50 is operating in the blower region LR2.

Further, the blower 10 of the present modification cooperates with other devices such as the so-called ceiling lighting 100, the air conditioner 102, and the smart speaker 104, and determines whether or not the user is in a sleeping state. Etc., and based on the estimation result, it may be automatically determined whether to operate in the sleep mode or another operation mode.

≪Third variant example≫
Subsequently, a third modification of the blower 10 shown in the above embodiment will be described. In the following description, the same reference numerals as those shown in the above-described embodiments and the above-mentioned modifications will be given the same reference numerals, and detailed description thereof will be omitted.

The blower 10 shown in the above embodiment performs a blower operation while swinging only in the vertical direction and adjusting the wind speed for each region defined in the vertical direction during operation in the good night mode. However, the present invention is not limited to this. Specifically, the blower 10 of this modification is made to swing in the left-right direction in addition to the up-down direction when the good night mode is selected, and the wind speed is set for each area defined in the up-down-left-right direction. Blow operation while adjusting.

Here, as shown in FIG. 12, it is defined that the region that can be swung by the blower 10 is composed of a plurality of regions in the vertical direction and the horizontal direction, respectively. Specifically, in the example shown in FIG. 12, the swingable region is divided into three regions in the vertical direction and five regions in the horizontal direction, and 15 regions as a whole are assumed. Of these regions, the region that is the central part in the left-right direction and is the lowest is the inner region I, and the region adjacent to the inner region I, that is, the region that is vertically, horizontally, and diagonally deviated from the inner region I. The region at the position is defined as the first outer region M, and the region outside the first outer region M is defined as the second outer region O. In the illustrated example, it is assumed that a person lies in the vicinity of the center of the bed 80 at bedtime, and the inner region I is the central portion in the left-right direction and the lowermost region. When each region is defined in this way, the second outer region O does not exist at a position directly adjacent to the inner region I, but only the first outer region M exists.

When the blower 10 of the third modification is operated in the good night mode, the left / right swing motor 22 and the up / down swing motor 40 are operated so that the blowing direction faces each region defined as described above. , The blower operation is performed while changing the blower strength for each area. In the good night mode, the blast intensity is controlled on the assumption that there is a sleeping person in the inner region I. Specifically, the blower 10 of the third modification performs the blow operation so that the wind speed Vi in the inner region I is lower than the wind speed Vm in the first outer region M and the wind speed Vo in the second outer region O (). Vi <Vm, Vi <Vo)). Further, the blower 10 performs the blow operation so that the wind speed Vo in the second outer region O becomes the maximum wind speed during the operation in the good night mode. The wind speed Vm in the first outer region M is a constant value between the wind speed Vi in the inner region I and the wind speed Vo in the second outer region O, or the wind speed Vm is gradually changed between the wind speeds Vi and Vo.

In the blower 10 of this modification, the blowing direction fluctuates in the vertical direction and the horizontal direction in the inner region I forming a part of the blowing region, and the first outer region M and the second outer region O outside the inner region I. Can be operated. Further, the blower 10 of this modification is operated so that the wind speed Vi in the inner region I is lower than the wind speed Vm in the first outer region M and the wind speed Vo in the second outer region O when operating in the good night mode. I do. Therefore, the blower 10 of this modification suppresses the strength of the direct wind that hits the user by installing and using the inner region I so as to face the front of the user, and the wind continues to hit the human body while sleeping. It is possible to reduce adverse effects such as coldness of the body and fatigue when waking up. Further, according to the blower 10 of the present modification, it is possible to construct a comfortable environment in which a comfortable wind flows through the room by the convection wind formed by the blown air to the first outer region M and the second outer region O.

In addition, like the blower 10 of the third modification, a plurality of regions are defined in the vertical direction and the horizontal direction, and a region (inner region I) in which a sleeping person is assumed to exist and a region thereof. When the ventilation conditions are changed in regions other than the regions (first outer region M and second outer region O), it is preferable to have a configuration in which the ventilation unit 50 at the start of operation in the sleep mode can be grasped. As a measure for grasping the position of the blower unit 50, a sensor for detecting the position of the blower unit 50 may be provided. In addition, the operating conditions for stopping the swinging operation in the left-right direction are satisfied, the operating conditions for stopping the ventilation by pressing the stop button, etc. are satisfied, and the operation is started in the good night mode. The blower unit 50 may be controlled to be returned to a predetermined reference position with a condition such as the condition being satisfied as a start condition. The reference position for returning the blower portion 50 may be any position, but for example, it is approximately the center of an angle range in which the blower portion 50 can be swung in the left-right direction, and the blower portion 50 is tilted downward by a predetermined angle. And so on. When the blower 10 is configured to be controlled to return the blower unit 50 to the reference position, the expected effect can be obtained only by the user installing the blower 10 with the reference position as a reference. Further, if the configuration is such that the blower returns to the reference position as described above, the blower 10 can be operated by simple operation control on the premise that the operation starts with the reference position as a reference.

Further, in the blower 10 of the third modification, the ion generator 70 may be arranged in the vicinity of the blower portion 50, for example. Further, when the ion generator 70 is provided, the ion generator 70 is stopped while the blower unit 50 is operating in the inner region I where the direct wind is generated, and the first outer region M where the convection wind is generated and the first outer region M. It is preferable to operate the ion generator 70 while the blower portion 50 is operating in the second outer region O.

Further, the blower 10 of the present modification cooperates with other devices such as the so-called ceiling lighting 100, the air conditioner 102, and the smart speaker 104, and determines whether or not the user is in a sleeping state. Etc., and based on the estimation result, it may be automatically determined whether to operate in the sleep mode or another operation mode.

In the following description, the same reference numerals as those shown in the above-described embodiments and the above-mentioned modifications will be given the same reference numerals, and detailed description thereof will be omitted.

Also in the blower 10 of the fourth modification, it is defined that the region where the blower portion 50 can swing is composed of a plurality of regions in the vertical direction and the horizontal direction, respectively, as in the third modification described above. When the blower 10 of the fourth modification is operated in the good night mode, the blower portion 50 is not swung in a path passing through the entire region as in the third modification, but is indicated by an arrow in FIG. As shown, the blower operation is performed while swinging the blower unit 50 so as to avoid the inner region I. By performing the operation in this way, it is possible to operate so as to generate a convective wind without generating a direct wind toward a sleeping person who is supposed to be in the inner region I. Therefore, the blower 10 of this modification is. By installing and using the inner area I so that it faces the front of the user, the strength of the direct wind that hits the user is suppressed, and the body gets cold due to the continuous wind hitting the human body while sleeping, or when waking up. It is possible to reduce adverse effects such as fatigue. Further, according to the blower 10 of the present modification, it is possible to construct a comfortable environment in which a comfortable wind flows through the room by the convection wind formed by the blown air to the first outer region M and the second outer region O.

The blower 10 shown as the fourth modification may operate the blower motor 54a under the condition that the wind speeds Vm and Vo are substantially the same in the first outer region M and the second outer region O, but the wind speed Vm , The blower motor 54a may be operated under different conditions of Vo. Specifically, as in the third modification, the wind speed Vm in the first outer region M may be constant at an intermediate value between the wind speeds Vi and Vo, or may be gradually changed between the wind speeds Vi and Vo. ..

Further, it is preferable that the blower 10 of the fourth modification also has a configuration capable of grasping the position of the blower portion 50 at the start of operation in the good night mode, similarly to the blower 10 of the third modification. As a measure for grasping the position of the blower unit 50, a sensor for position detection may be provided, or control may be performed to return the blower unit 50 to a predetermined reference position when the swing operation is stopped. .. When the blower 10 is configured to be controlled to return the blower unit 50 to the reference position, the expected effect can be obtained only by the user installing the blower 10 with the reference position as a reference. Further, if the configuration is such that the blower returns to the reference position as described above, the blower 10 can be operated by simple operation control on the premise that the operation starts with the reference position as a reference.

Further, in the blower 10 of the fourth modification, the ion generator 70 may be arranged in the vicinity of the blower portion 50, for example.

Further, the blower 10 of the present modification cooperates with other devices such as the so-called ceiling lighting 100, the air conditioner 102, and the smart speaker 104, and determines whether or not the user is in a sleeping state. Etc., and based on the estimation result, it may be automatically determined whether to operate in the sleep mode or another operation mode.

≪Fifth variant example≫

In the following description, the same reference numerals as those shown in the above-described embodiments and the above-mentioned modifications will be given the same reference numerals, and detailed description thereof will be omitted.

The blower 10 of the fifth modification is capable of adjusting the range (swing width) that the blower 50 can swing in the left-right direction to a plurality of angle ranges during operation in the good night mode. Specifically, the blower 10 of the fifth modification is as shown in FIG. The swing width in the left-right direction can be switched to an angle range of three stages of A1 degree, A2 degree, and A3 degree (for example, A1 degree = 60 degrees, A2 degree = 90 degrees, and A3 degree = 120 degrees).

In a general electric fan, the left-right swing width in the blowing direction is set to be wider than the area where the user is, and the direct wind is suppressed from continuing to hit the person. The blower 10 of this modification can suppress the continuous direct wind from hitting a person even when the fan 10 is operated in the good night mode (convection wind mode) by narrowing the swing width in the left-right direction to the area where the user is. .. As a result, it is possible to create a comfortable environment in which a comfortable wind flows through the room by generating convection wind while reducing the adverse effects such as the coldness of the human body caused by the continuous wind hitting the human body while sleeping and the fatigue when waking up. ..

Further, the blower 10 of the present modification cooperates with other devices such as the so-called ceiling lighting 100, the air conditioner 102, and the smart speaker 104, and determines whether or not the user is in a sleeping state. Etc., and based on the estimation result, it may be automatically determined whether to operate in the sleep mode or another operation mode.
The blower 10 of the fifth modification has a swing width (A1 degree = 60 degrees, A2 degrees = 90 degrees, A3 degrees = 120 degrees) of the blower portion 50 in the left-right direction and a range of motion in the vertical direction (specifically, A3 degrees = 120 degrees). The ratio of 105 °) is set so as not to be an integral multiple. This is because the blast trajectory when swinging up, down, left, and right at the same time is almost random, and the indoor air is agitated evenly.

The wind speed detection unit 64 can detect the wind speed at the arranged place. The data related to the wind speed detected by the wind speed detection unit 64 can be transmitted to the control board 26 of the blower 10. The control board 26 controls the wind speed by swinging the blower unit 50 to switch the blower direction or adjusting the output of the blower motor 54a based on the data related to the wind speed received from the wind speed detection unit 64. For example, it is preferable that the wind speed detection unit 64 detects whether or not a convection wind is generated so that the sleeping user can spend comfortably, and controls the wind speed. Further, for example, in order to efficiently circulate the air in the room, the control board 26 performs a process of determining in which direction and at what wind speed it is optimal to blow the air, and the swinging motion and the wind speed of the blowing unit 50 are determined. It may be controlled automatically. Further, the blower 10 makes it possible to detect the position where the remote controller 62, the smart speaker 104, etc. are present, estimates the place where a person is based on the position detection result, and the direct wind and the convection wind reach an appropriate place. As described above, the operation of the left / right swing motor 22, the up / down swing motor 40, the blower motor 54a, and the like may be controlled.

Further, the blower 10 of the sixth modification cooperates with other devices such as the so-called ceiling lighting 100, the air conditioner 102, and the smart speaker 104 to determine whether or not the user is sleeping. It may be estimated at 26 or the like, and it may be automatically determined whether to operate in the sleep mode or another operation mode based on the estimation result.

The feature is that the backlash is offset by applying a downward urging force to the blower portion on condition that the blower portion swings upward beyond the angle. It is good to be.

According to the above-mentioned configuration, even if the swinging direction is switched downward after the blower portion 50 swings upward beyond a predetermined angle, there is a possibility of knocking. It is possible to provide a blower 10 that can be suppressed to a minimum.

Hereinafter, the blower 10 having the configurations (1) to (5) will be described in detail with reference to the drawings.

16 and 17 show the blower 10 according to the seventh modification with the cover and the like removed so that the internal structure in the vicinity of the accommodating portion 38 can be seen. As shown in FIGS. 16 to 19, the accommodating portion 38 includes a vertical swing motor 40 and a vertical swing mechanism portion 42. The vertical swing mechanism portion 42 has a plurality of gears meshed with each other, and is capable of transmitting the power of the vertical swing motor 40 to the blower portion 50 side. Specifically, the vertical swing motor 40 has an output shaft (not shown) protruding toward the back side of the paper surface of FIG. An output gear (not shown) is provided on the output shaft of the vertical swing motor 40 so that it can rotate integrally with the output shaft.

On the other hand, as shown in FIGS. 16 and 19, the vertical swing mechanism portion 42 has a first gear 120. The first gear 120 is formed by arranging the input side gear portions 122 and the intermediate gear portions 124 having different gear ratios in the axial direction. The first gear 120 meshes with the output gear provided in the vertical swing motor 40 in the input side gear portion 122. Further, the first gear 120 meshes with the second gear 130 on the blower portion 50 side in the intermediate gear portion 124. The second gear 130 is made rotatable integrally with the blower portion 50.

Specifically, as shown in FIG. 16 and the like, the present embodiment has a rotating shaft 134 that penetrates the central portion of the second gear 130 and is provided so as to be rotatable in conjunction with the second gear 130. .. Further, as shown in FIGS. 17 and 18, the rotating shaft 134 penetrates the side wall portions 152 and 152 provided on both sides of the accommodating portion 38 and is taken out to the outside. Both ends of the rotating shaft 134 are connected to holding portions 158, 158 arranged along the side wall portions 152, 152. Further, the holding portions 158 and 158 are connected to the blower portion 50. More specifically, the holding portion 158 has a blower connecting portion 158a and a repelling member holding portion 158b. The blower connection portion 158a is a portion fixed to the back surface of the blower portion 50. In the present embodiment, the blower portion connecting portion 158a is fixed to the back surface side of the blower portion 50 by a fixing member such as a screw. As a result, the holding portion 158 and the blowing portion 50 are integrated. Therefore, as shown in FIGS. 19A and 19B, the blower 10 rotates the blower portion 50 in the vertical direction around the axial center position of the second gear 130 by rotating the second gear 130. Can be moved.

Further, as shown in FIGS. 19 and 20, in the blower 10 of the present embodiment, when the first gear 120 is rotated in the positive direction (counterclockwise direction in the illustrated state), the second gear 130 is rotated in the positive direction (illustrated). Rotate clockwise in the state). As a result, the blower portion 50 rotates upward. On the other hand, when the first gear 120 is rotated in the reverse direction (clockwise in the illustrated state), the second gear 130 is rotated in the reverse direction (counterclockwise in the illustrated state). As a result, the blower portion 50 rotates downward. In this way, the blower 10 can switch the rotation direction of the blower unit 50 in the vertical direction by switching the output direction of the rotational power by the vertical swing motor 40 and changing the rotation direction of the first gear 120. can. In the following description, unless otherwise specified, the rotation direction of the first gear 120 and the second gear 130 when the blower portion 50 rotates upward is forward or forward rotation direction, and the blower portion 50 is downward. The rotation direction of the first gear 120 and the second gear 130 when rotating toward is described as a reverse direction or a reverse rotation direction.

Further, as shown in FIGS. 16 to 20, an urging means 150 is provided on the back surface side of the blower portion 50. As shown in FIGS. 17 and 20, the urging means 150 has an elastic member 154 and a contact portion 156. As shown in FIG. 17, the urging means 150 is arranged so as to be substantially symmetrical with respect to the accommodating portion 38 on both sides (positions adjacent to the axial direction of the first gear 120 and the second gear 130). .. That is, in the urging means 150, the side wall portion 152, the elastic member 154, and the contact portion 156 are arranged on the back surface side of the blower portion 50 at predetermined intervals in the axial direction of the first gear 120 and the second gear 130. Has been done. The urging means 150 may be referred to as a backlash canceling mechanism unit.

In the embodiment shown in FIGS. 16 and 20, the elastic member 154 is configured by a thin plate spring in which a thin metal plate is bent in a substantially “dogleg” shape. Specifically, the elastic member 154 is formed by integrally forming an arc portion 154a, a first arm portion 154b, and a second arm portion 154c. The arc portion 154a is a portion formed by bending a thin metal plate into an arc shape. Further, the first arm portion 154b is a linear portion formed so as to be continuous with one end side of the arc portion 154a. The second arm portion 154c is a linear portion formed so as to be continuous with the other end side of the arc portion 154a. The elastic member 154 is cantilevered by the side wall portion 152 by inserting the first arm portion 154b into the insertion hole 158c of the holding portion 158 provided at a position adjacent to the side wall portion 152 described above. In a state where the elastic member 154 is held by the side wall portion 152, the second arm portion 154c is a free end and is exposed to the outer peripheral side of the side wall portion 152. The elastic member 154 is held in such a posture by the holding portion 158, and is rotatable together with the holding portion 158 in conjunction with the vertical swinging motion of the blower portion 50.

More specifically, the elastic member 154 is held by the holding portion 158 as shown in FIGS. 16 to 18. The holding portion 158 is provided at a position adjacent to both outer sides of the second gear 130 in the axial direction with respect to the side wall portion 152. The elastic member 154 is held by the elastic member holding portion 158b of the holding portion 158, and is rotatable in conjunction with the vertical swinging motion of the blower portion 50.

Specifically, the elastic member holding portion 158b is integrated with the blower portion connecting portion 158a connected to the blower portion 50. The elastic member holding portion 158b is arranged so as to be rotatable in the holding portion arranging portion 136 provided on the outer side in the axial direction of the rotating shaft 134 with respect to the side wall portion 152. Further, the elastic member holding portion 158b is supposed to be able to hold one end side of the elastic member 154. The elastic member holding portion 156b may be any as long as it can hold the elastic member 154, but in the present embodiment, the insertion hole 158c capable of holding the first arm portion 154b of the elastic member 154 is used. It is formed. Specifically, the insertion hole 158c inserts the first arm portion 154b so as to penetrate the peripheral surface of the elastic member holding portion 158b at a position off the center of the elastic member holding portion 158b formed in a cylindrical shape. It is a possible through hole. The elastic member 154 is held by inserting the first arm portion 154b into the insertion hole 158. Therefore, the elastic member 154 is held by the holding portion 158 in a posture in which the second arm portion 154c projects outward in the radial direction of the elastic member holding portion 158b, and is interlocked with the vertical swinging motion of the blower portion 50. Then, it is rotated together with the holding portion 158.

As shown in FIGS. 16 and 17, the contact portion 156 is provided at the tip end portion of the curved portion 136a provided so as to be curved in an arc shape in the holding portion arranging portion 136. Specifically, the curved portion 136a is curved along the outer periphery of the elastic member holding portion 158b on the radial outer side with respect to the above-mentioned elastic member holding portion 158b. The contact portion 156 is provided at the tip end portion of the curved portion 136a. As shown with hatching in FIGS. 19 and 20, when the blower portion 50 rotates around the axial center position of the second gear 130, the contact portion 156 is provided together with the blower portion 50 and the holding portion 158. It is located on the rotating orbit of the rotating elastic member 154. As shown in FIG. 20A, the contact portion 156 is located at a position away from the elastic member 154 in the region where the elevation angle of the blower portion 50 is low. Specifically, the contact portion 156 is in the positive direction of the second gear 130 with respect to the position where the elastic member 154 is present when the elevation angle of the blower portion 50 is in a region lower than a predetermined angle (not shown). In the state, it exists in a position deviated in the clockwise direction). Therefore, when the elevation angle of the blower portion 50 is lower than a predetermined angle, the contact portion 156 is located at a position away from the elastic member 154. However, the contact portion 156 is in a position where the blower portion 50 rotates upward and comes into contact with the second arm portion 154c of the elastic member 154 when the elevation angle reaches a predetermined angle of 90 degrees or less. When the blower portion 50 is rotated further upward while the abutting portion 156 is in contact with the second arm portion 154c of the elastic member 154, the elastic member 154 is compressed by the abutting portion 156 and the second The arm portion 154c is elastically deformed in a direction approaching the first arm portion 154b side. When the blower portion 50 is rotated until the elevation angle reaches approximately 90 degrees, the elastic member 154 is compressed to the maximum and is elastically deformed as shown in FIG. 20 (b).

The urging means 150 has the above-mentioned configuration. Therefore, in the urging means 150, the elastic force of the elastic member 154 is provided in a state where the blower portion 50 is tilted upward to a region equal to or higher than the position where the second arm portion 154c of the elastic member 154 abuts on the contact portion 156. Is generated, and the second gear 130 can be urged in the reverse rotation direction (the rotation direction when the blower portion 50 rotates downward). Further, as the elevation angle of the blower portion 50 approaches 90 degrees, the amount of compression of the elastic member 154 increases, and the urging force acting on the second gear 130 increases by that amount. As a result, the urging means 150 can cancel the backlash between the intermediate gear portion 124 of the first gear 120 and the second gear 130 when the elevation angle of the blower portion 50 is equal to or greater than a predetermined angle.

More specifically, if the urging means 150 does not exist, as shown in FIG. 21 (a), the tooth side surface 126a on the forward rotation direction side of the teeth 126 forming the intermediate gear portion 124 and the second side surface 126a. The intermediate gear portion 124 and the second gear 130 rotate in the forward rotation direction (directions A1 and A2 in the figure) while contacting the tooth side surface 132a on the reverse rotation direction side of the teeth 132 of the two gears 130. .. At this time, there is a gap 110 corresponding to the backlash between the tooth side surface 126b on the reverse rotation direction side of the tooth 126 forming the intermediate gear portion 124 and the tooth side surface 132b on the forward rotation direction side of the tooth 132 of the second gear 130. It is formed. With such a gap 110 formed, the blower section 50 swings until the elevation angle of the blower section 50 becomes approximately 90 degrees, and then the intermediate gear section 124 reverses to swing the blower section 50 downward. When it starts to rotate, the blower portion 50 causes knocking. That is, as shown in FIG. 21B, after the intermediate gear portion 124 starts rotating in the opposite direction (direction of arrow B1 in the drawing), the tooth side surface 126b of the intermediate gear portion 124 and the teeth of the second gear 130 At the stage of contact with the side surface 132b, the above-mentioned gap 110 is eliminated. On the other hand, a state in which a gap 112 corresponding to the backlash is formed between the tooth side surface 126a on the reverse rotation direction side of the intermediate gear portion 124 and the tooth side surface 132a on the reverse rotation direction side of the second gear 130. become. When the intermediate gear portion 124 further rotates in the reverse direction from this state, the teeth 132 of the second gear 130 are pushed and moved by the teeth 126 of the intermediate gear portion 124 as shown by the arrow B2 in FIG. 21 (b). At this time, since the gap 112 is formed at a position adjacent to the tooth 132 in the reverse rotation direction, the second gear 130 and the blower portion 50 rotate rapidly, causing knocking.

However, in the blower 10 of this modification, the urging means 150 can suppress the knocking of the blower portion 50 as described above. That is, in the blower 10 of this modification, when the blower portion 50 swings upward beyond a predetermined angle, the elastic member 154 is used as shown by the arrow F in FIG. 22 (a). The urging force acts on the second gear 130. Due to the action of this urging force, the tooth side surface 126b on the reverse rotation direction side of the tooth 126 of the intermediate gear portion 124 and the tooth side surface 132b on the forward rotation direction side of the tooth 132 of the second gear 130 are in contact with each other, while the intermediate gear portion is in contact with each other. The 124 and the second gear 130 rotate in the forward rotation direction (directions of arrows C1 and C2 in the figure). Further, when the swing direction is switched downward after the blower portion 50 exceeds a predetermined angle and rises until the elevation angle becomes approximately 90 degrees, the tooth side surfaces 126a and 132b are as shown in FIG. 22 (b). The intermediate gear portion 124 and the second gear 130 rotate in opposite directions (directions of arrows D1 and D2 in the figure) while the intermediate gear portion 124 and the second gear 130 are in contact with each other. As a result, the blower unit 50 can smoothly swing the head without causing knocking even when the swing direction is switched at a position where the elevation angle is approximately 90 degrees.

On the other hand, when the blower portion 50 exists in a region below the position where the second arm portion 154c of the elastic member 154 abuts on the contact portion 156, the elastic force is generated in the elastic member 154. Instead, the second gear 130 is in a state where it can freely rotate without receiving an urging force from the elastic member 154. Therefore, the blower unit 50 can freely rotate without receiving any load from the elastic member 154 in a state where the elevation angle is less than a predetermined angle.

As with the other modifications, the blower 10 of this modification is not limited to the above-mentioned configuration, and the configuration can be appropriately changed without departing from the spirit of the invention. For example, in the present modification, an example in which a leaf spring is used as the elastic member 154 is shown, but the present invention is not limited to this, and any person can generate an elastic force. May be. For example, as shown in FIGS. 23 (a) and 23 (b), the elastic members 155 and 157 may be formed by processing a metal wire. Specifically, the elastic members 155 and 157 include arc portions 155a and 157a corresponding to the arc portions 154a of the elastic member 154 described above, first arm portions 155b and 157b corresponding to the first arm portions 154b, and first arm portions 157b and 157b. The second arm portions 155c and 157c corresponding to the two arm portions 154c are integrally formed. If a wire rod such as the elastic members 155 and 157 is used, the elastic force can be dispersed and exerted, and further effects such as improvement of durability can be expected. Further, the vertical swing mechanism unit 42 is not limited to transmitting the driving force of the vertical swing motor 40 to the blower unit 50 by a plurality of gears meshing with each other, and the blower unit 50 by a link mechanism or other rotation transmission mechanism. Includes a structure that realizes the vertical swing motion of.

In the following description, the same reference numerals as those shown in the above-described embodiments and the above-mentioned modifications will be given the same reference numerals, and the illustration and detailed description will be omitted as appropriate.

As shown in FIG. 24, the blower 10 has a back cover 160 provided on the back side of the blower portion 50 so as to cover the accommodating portion 38. The back cover 160 has a notch 162 provided so that the accommodating portion 38 is partially exposed. The notch 162 has an upper edge portion 164 extending in the width direction of the blower portion 50. The notch 162 is formed so that there is almost no gap between the upper edge portion 164 and the outer peripheral surface 38a of the accommodating portion 38. Further, the outer peripheral surface 38a is extended to the inside of the back cover 160. As a result, even when the blower portion 50 is tilted most downward, the end portion of the outer peripheral surface 38a is not exposed to the outside through the notch 162. Since the blower 10 has such a configuration, for example, at the timing when the blower portion 50 starts to swing upward from the state where the blower portion 50 is tilted most downward, the notch 162 and the outer peripheral surface of the accommodating portion 38 are formed. It is possible to prevent a finger or the like from being accidentally pinched between the 38a and the 38a.

Further, the blower 10 has a recess 170 on the lower side of the back cover 160. The recesses 170 are provided on both sides in the width direction with respect to the accommodating portion 38. By providing such a recess 170, it is possible to prevent fingers or the like from being pinched between the back cover 160 and the accommodating portion 38 when the blower portion 50 swings upward. can.
