  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
As shown in FIG. 1, the blower of the present embodiment is installed with a part embedded in an opening provided in the ceiling.

  The main body 1 of the blower is a box that can be embedded in the ceiling, has a circular opening 2 on the bottom surface, and a suction port 3 that sucks air into the main body on the center side of the opening 2 and an opening 2. The blower outlet 4 which discharges air to indoor space is provided in the outer peripheral side.

  In the main body 1, a ventilation path 4 </ b> A that connects the suction port 3 and the outlet 4, and a fan motor 5 that is provided in the ventilation path 4 </ b> A and blows out air sucked from the suction port 3 from the outlet 4 and circulates room air. And an odor detector 6 for detecting the odor of the air sucked from the inlet 3 and sending a signal in accordance with the odor level, and an ion generator 7 for purifying the indoor air discharged from the outlet 4 ing.

  In addition, the opening 2 has a shutter 8 that is fully opened at the opening 2 or that leaves a fan-shaped portion and closes the remaining portion of the opening 2, and a shutter rotation unit that rotationally drives the shutter 8 at the opening 2. 9 and shutter opening / closing means 10 for adjusting the opening angle of the shutter 8.

  Further, in the main body 1, the shutter rotating means 9 and the shutter opening / closing means 10 are operated to control the opening direction and the opening angle of the opening 2, and the fan motor 5 and the ion generator 7 are operated to ionize the indoor space. The control part 11 which sends the air containing is provided.

  Here, in order to detect the odor level of only the air sucked from the current shutter opening direction, the odor detection unit 6 is in the ventilation path 4A and detects the odor of the airflow passing through the passage by the operation of the fan motor 5. In order to be able to be detected, the fan motor 5 is arranged on the suction port side at a position away from the suction port 3.

  In addition, it is important for the odor detection unit 6 to accurately determine the level of odor of the airflow passing through the passage. For this reason, the odor detection unit 6 performs deodorization by the ion generation unit 7. It arrange | positions in the position close | similar to the blower outlet 4 rather than the odor detection part 6 in the ventilation path 4A of the main body 1 so that the odor detection of the front air may be performed.

  As shown in FIG. 2, the control unit 11 determines that the odor level of the indoor space is “high” based on the signal from the odor detection unit 6 and the odor level of the indoor space is “high” when the value is greater than a predetermined value. An odor level determination means 12 for determining that the odor level of the indoor space is “low”, an angle data storage unit 13 for storing control target values of the shutter open / close angle and shutter rotation angle, Based on the signal from the odor level determination means 12, the target angle setting means 14 that reads the data in the angle data storage unit 13 and transmits it to the shutter angle control means 15, and the shutter rotation means 9 and the A shutter angle control means 15 for operating the shutter opening / closing means 10 is provided.

  In the present embodiment, a reference value of a predetermined size is provided, and based on this reference value, the determination of the odor level “low” and the determination of the odor level “high” is made, and the occurrence of odor is “none”. ”And“ Yes ”.

  In addition, the control unit 11 outputs a signal from the odor detection unit 6 in synchronization with a signal transmitted from the target angle setting unit 14 to the shutter angle control unit 15 when the odor level changes from “small” to “large”. An odor position specifying means 16 is provided for storing and storing in the angle data storage unit 13 by specifying the direction and range of odor generation based on the stored data.

  The odor position specifying means 16 captures and stores the signal from the odor detection unit 6 in synchronization with the signal transmitted from the target angle setting means 14 to the shutter angle control means 15, and stores the odor level in the current shutter opening direction. The odor data storage unit 17 stores the odor, the position where the odor is generated based on the data stored in the odor data storage unit 17, and the shutter rotation angle and the shutter opening / closing angle according to the odor generation position are set as angle data. Data analysis means 18 to be sent to the storage unit 13 is provided.

As shown in FIG. 3, the angle data storage unit 13 includes an initial operation data unit 19 that stores a shutter rotation angle θ ₀ and a shutter opening / closing angle φ ₀ when the odor level is lower than a predetermined value, and an odor level. The odor generation position search data unit 20 for storing the shutter rotation angles θ ₁ to θn and the shutter opening / closing angles φ ₁ to φn when the state is changed to a state higher than a predetermined value, and the odor generation direction is specified. An odor generation position data unit 21 for storing the shutter rotation angle θx and the shutter opening / closing angle φx is provided.

  The odor generation position data section 21 does not store the shutter opening / closing angle and shutter rotation angle data in the initial state, and after the odor position specifying means 16 specifies the odor generation direction and range, the odor generation position data section 21 is set to the odor generation position. The combined angle data is stored.

  The shutter opening / closing angle φ and the shutter rotation angle θ are defined as shown in FIG.

That is, the shutter opening / closing angle φ is an angle from the initial position φ ₀ of the shutter opening / closing means 10 to the portion where the shutter opening / closing means 10 opens the shutter, and the shutter rotation angle θ is the initial position φ of the shutter rotation means 9. The angle is from ₀ to the amount by which the shutter rotation means 9 is rotationally driven.

  In the above configuration, the target angle setting unit 14 reads the angle data stored in the angle data storage unit 13 based on the signal from the odor detection unit 6, and controls the shutter rotation angle and shutter opening / closing angle of the blower. The operation of identifying the position where the odor is generated and applying air containing ions locally in the direction of the odor in the space will be described with reference to FIG.

When the main body 1 of the blower is turned on, the target angle setting means 14 reads the data stored in the initial operation data section 19 of the angle data storage section 13 as shown in STEP 1 of FIG. Since the initial operation data section 19 stores angle data of the shutter opening / closing angle φ ₀ = 360 ° and the shutter rotation angle θ ₀ = 0 °, the target angle setting means 14 uses the shutter opening / closing angle φ ₀ = 360 °. The shutter rotation means 9 and the shutter opening / closing means 10 are driven so that the shutter rotation angle θ ₀ = 0 ° (fully opened state), and the shutter 8 is fully opened.

  Then, the control unit 11 rotates the fan motor 5 so that the air in the indoor space flows into the suction port 3, the odor level of the air passing through the suction port 3 is measured by the odor detection unit 6, and ions are generated by the ion generation unit 7. The contained air is blown out into the indoor space through the air outlet 4. Since the shutter 8 is fully opened in the initial state, air in the entire indoor space circulates.

  Here, if the source of the odor exists in the indoor space, the odor-containing air flows from the suction port 3 and reaches the odor detection unit 6. Since the odor detection unit 6 outputs a signal corresponding to the intensity of the odor, the odor level determination means 12 determines the signal, and if the signal from the odor detection unit is a predetermined value or more, the odor detection unit 6 Judge that the original appeared.

  However, in the initial state, the shutter 8 is fully opened, and air is sucked from all directions of the indoor space, so that the position where the odor is generated cannot be specified. Therefore, in this embodiment, the position where the odor is generated is specified by narrowing the shutter opening / closing angle and step-driving the shutter rotation angle, and the operation will be described below.

  As shown in STEP 2, when the odor level determination unit 12 determines that the odor level is “low” based on the signal from the odor detection unit 6, the target angle setting unit 14 performs the angle data storage unit as a normal operation. 13 reads the data stored in the initial operation data section 19.

At this time, for example, by storing the angle data of the shutter opening / closing angle φ ₀ = 360 ° and the shutter rotation angle θ ₀ = 0 ° in the initial operation data unit 19, the odor level determination unit 12 sets the odor level. When it is determined as “small”, the target angle setting means 14 reads the data stored in the initial operation data section 19 and performs an operation of circulating the air in the entire room by fully opening the shutter opening. It will be. That is, it is determined that no odor is generated in the indoor space, and the operation of deodorizing the entire room is continued.

  Next, when the odor level determination means 12 detects that the odor level has changed from “low” to “high”, it is determined that odor has occurred in the indoor space, and the process goes to STEP 3 to shift to the odor generation position search operation. move on.

  When the odor level determination means 12 determines that odor has occurred in the indoor space, as shown in STEP 3, the target angle setting means 14 is stored in n = 1 part of the odor generation position search data section 20 as shown in FIG. By reading the data (shutter opening angle φ1) and sending a signal to the shutter angle control means 15, the shutter opening / closing angle is narrowed. Thereby, the opening part of the shutter 8 becomes narrow and it becomes possible to limit the direction of the air suck | inhaled from indoor space.

  Then, after T [sec] has elapsed, as shown in STEP 4, the target angle setting means 14 reads the data stored in the next storage unit (n = 2), and the shutter opening angle φ2 does not change. The shutter opening direction is changed according to the shutter rotation angle θ2. Here, for example, the odor occurrence position search data section 20 includes a shutter opening angle φ1 = 30 °, φ2 = 30 °, φ3 = 30 °,..., Φn = 30 ° and a shutter rotation angle θ1 = 0 °, θ2. = 30 °, θ3 = 60 °,..., Θn = 330 ° is stored, so that the target angle setting means generates odors every predetermined time T [sec] in order from the data of n = 1 For example, in the above example, the position search data unit 20 is read, and the opening direction of the shutter is changed by 30 ° while maintaining the opening angle of 30 °, and step driving for one rotation is performed. This operation is called an odor generation position search operation.

  As a result, the direction of the shutter opening is rotated, and the region of the air sucked from the indoor space is changed.

  The shutter opening angle φ and the shutter rotation angle θ can be arbitrarily set.

  During the odor generation position search operation, as shown in FIG. 6, the odor data storage unit 17 reads the shutter rotation angle θ sent from the target angle setting unit 14 to the shutter angle control unit 15 to thereby open the current shutter opening. The direction and odor detection data can be linked.

  Further, since the interval at which the target angle setting unit 14 sends a signal to the shutter angle control unit 15 is set to a predetermined time T [sec], the odor data storage unit 17 causes the target angle setting unit 14 to send a signal to the shutter angle control unit 15. Incorporation of the odor value from the odor detection unit 6 is started in synchronization with the transmission timing, and stored in correspondence with the data in the shutter opening direction. That is, in synchronization with the timing at which the target angle setting unit 14 sends the next angle data signal to the shutter angle control unit 15, the odor data storage unit 17 adds the odor from the odor detection unit 6 to the next shutter opening direction data. By changing the value acquisition destination, the current odor value in the shutter opening direction can be stored. Thereby, the odor value in the current indoor air suction direction can be accumulated as data.

  As shown in STEP 5, the target angle setting means 14 sequentially reads the data stored in the odor generation position search data section 20 every predetermined time T [sec]. When the target angle setting means 14 sequentially reads the data stored in the odor occurrence position search data unit 20 and reads the data for one rotation, the odor data storage unit 17 determines that the odor data in all directions is stored, Proceed to STEP 6.

  When the odor data storage unit 17 stores data for one round corresponding to the shutter rotation angle θ, the data analysis means 18 starts analyzing each data stored in the odor data storage unit 17 as shown in STEP 6. . By rearranging the signals from the odor detection unit 6 accumulated in each shutter opening direction in the descending order, it is possible to determine in which direction the strongest odor is generated, and in the region where the odor data is the largest. The shutter opening angle and the shutter rotation angle are set as φx and θx, respectively, and stored in the odor generation position data section 21 as shown in FIG. This operation is called an odor generation position specifying operation.

  Further, for example, not only the region where the maximum value or average value of the odor data is the largest, but also data of a plurality of regions is taken up, and if it is an adjacent region, the shutter opening / closing angle is added and the shutter opening angle φx is obtained. Then, it is possible to calculate the shutter opening angle φx according to the odor generation range. As a result, when the odor source is larger than the initial shutter opening angle φ1, the shutter opening angle φ is widened according to the odor generation range, and ions are efficiently matched to the odor source size. It is possible to apply air containing air.

  When the data analysis unit 18 calculates the shutter opening / closing angle φx and the shutter rotation angle θx and stores them in the odor generation position data unit 21 of the angle data storage unit 13, the target angle setting unit 14 converts the angle data storage unit as shown in STEP7. The shutter opening / closing angle φx and the shutter rotation angle θx stored in the odor generation position data section 13 are read and sent to the shutter angle control means 15. As a result, the shutter opening direction is directed to the position where the odor is generated, and air containing ions is locally applied toward the odor in the space. This is called an odor removal operation.

  From the above, when an odor source appears in the indoor space, the direction of the air sucked from the indoor space is limited by narrowing the opening area of the shutter 8, and the odor level of the air sucked from the limited direction is accumulated. By accumulating and comparing the rotation of the opening area for one rotation, the direction of odor generation is specified, and by controlling the opening area of the shutter toward the specified direction, ions are included in the direction of odor generation. By applying air and circulating air only in the direction of the odor generation position in the indoor space, it is possible to suppress the generation of odor more efficiently than a conventional blower that circulates air in the entire room.

  Next, the operation when the odor source in the indoor space is removed by the odor removing operation will be described. As shown in STEP 8, in the odor removal operation, while the odor level determination means 12 determines that the odor level is “high” based on the signal from the odor detection unit 6, the deodorization based on the odor is not performed. The target angle setting means 14 reads the data stored in the odor generation position data section 21 of the angle data storage section 13 and directs the shutter opening direction to the odor generation position in the indoor space. to continue. When the odor level determining means 12 detects that the odor level has changed from “high” to “small”, it is determined that the deodorization of the odor of the indoor space has been completed and the process returns to STEP 1 and the target angle setting means 14 The initial operation data unit 19 of the angle data storage unit 13 is read, and the shutter opening is fully opened to return to the initial operation state and perform the operation of circulating the air in the entire room.

  As described above, when the odor is generated, the air is circulated locally toward the odor of the indoor space. When the removal of the odor is finished, the entire room is circulated. By automatically switching to the operation of circulating air, a blower capable of efficiently suppressing the source of the odor of the indoor space is obtained by automatically determining the operation mode according to the odor status of the indoor space.

  The blower according to the present invention determines the odor level of the indoor space based on the signal from the odor detection unit, and when the odor level is lower than a predetermined value and when the odor level changes to a higher state, the direction of odor generation is By identifying the odor generation position by controlling the shutter opening / closing angle and the shutter rotation angle and detecting the odor level in each direction by changing the shutter opening direction according to the specified time. The shutter opening / closing angle and the shutter rotation angle can be controlled according to the position where the odor occurs, so when the odor occurs in the indoor space, the shutter opening is squeezed and locally aligned with the position where the odor is generated. Air containing ions can be applied, and the air in the entire room is circulated to send air containing ions regardless of the position where odors are generated in the conventional indoor space. Than machine it is possible to perform the blowing operation tailored to the occurrence position of the smell, it is useful as a user-friendly air blower.
