Description

  The present invention relates to a mechanism for sending air.

  In general, in an air purifier, when increasing the amount of air blown from the air outlet, it is preferable to increase the opening area of the air outlet to lower the wind speed or to make the air flow to be blown uniform. If comprised in this way, it will become possible to reduce a user's discomfort and to suppress the rise of the dust by disturbance of an airflow. On the other hand, in the first prior art described in, for example, Patent Document 1, in order to reduce the thickness of the air cleaner, the fan and the filter are vertically connected, and the wind direction is bent vertically in the air passage connecting them. Is adopted.

Is adopted. Moreover, in the 3rd prior art described in patent document 3, while combining the photocatalyst filter provided in the suction inlet and the deodorizing agent provided in the blower outlet in a deodorizing filter, from a suction mouth to a blower outlet. A configuration is adopted in which air is blown from a large opening area by changing the wind direction vertically.

As shown in this figure, the air cleaner includes a casing 1, a blower unit 6, an air cleaning device 8, a suction rear panel 9, a wind direction control plate 10, and the like. The casing 1 constitutes the outline of the air purifier and is formed thin in the front-rear direction, and includes a front panel 2, a rear panel 3, left and right side panels (not shown), a suction port 4, and The blower outlet 5 is provided. The casing 1 accommodates a blower unit 6, an air cleaning device 8, a wind direction control plate 10, and the like, and an upstream space 1A and a downstream space 1B are formed as described later.

  The front panel 2 constitutes the front portion of the casing 1 and is formed, for example, on a flat plate or the like, and extends in the vertical direction and the horizontal direction of the air cleaner. In the following description, the front-rear direction of the air cleaner is defined as the left-right direction in FIG. 1, and the left-right direction of the air cleaner is defined as the direction perpendicular to the paper surface of FIG. The front panel 2 is disposed so as to be inclined in the front-rear direction so that the upper end portion is located behind the lower end portion. Further, the vertical direction of the air purifier coincides with the vertical direction in FIG.

  The back panel 3 constitutes the back surface portion (rear surface portion) of the casing 1 and is formed, for example, on a flat plate or the like, and extends in the vertical direction and the horizontal direction of the air cleaner. The back panel 3 is disposed to face the back side of the front panel 2, and an upstream space 1 </ b> A and a downstream space 1 </ b> B that are spaces in the casing 1 are formed between the front panel 2 and the back panel 3. Has been. Moreover, the site | part which faces the blower outlet 5 among the back panels 3 comprises 3 A of blower outlet facing parts. In the present embodiment, the case where the front panel 2 and the back panel 3 are formed of flat plates has been exemplified. However, in the present invention, these panels 2 and 3 are not necessarily formed flat.

  The suction port 4 is an opening for sucking air into the upstream space 1 </ b> A of the casing 1, and opens, for example, on the lower side of the front panel 2. On the other hand, the blower outlet 5 is an opening for blowing the air sucked into the casing 1 to the outside from the downstream space 1 </ b> B. For example, the blower outlet 5 opens to the upper side of the front panel 2 and is above the suction inlet 4. Are separated. The opening area of the outlet 5 is set larger than the opening area of the suction port 4. FIG. 1 illustrates a case where the suction port 4 is provided at the lower end portion of the front panel 2 and the air outlet 5 is provided at the upper end portion of the front panel 2. FIG. 1 illustrates the case where there are one suction port 4 and one outlet 5, but in the present invention, at least one of the suction port 4 and the outlet 5 is constituted by two or more openings. May be.

  The blower unit 6 is provided between the inlet 4 and the outlet 5 in the casing 1. That is, the blower unit 6 is disposed above the suction port 4 and below the air outlet 5 and the air outlet facing portion 3A of the rear panel 3. The blower unit 6 is disposed in contact with the front panel 2 and the back panel 3 of the casing 1. With this arrangement, the space in the casing 1 is divided into an upstream space 1 </ b> A that communicates with the suction port 4 and a downstream space 1 </ b> B that communicates with the air outlet 5.

  The blower unit 6 sucks air from the upstream space 1A located on the suction port 4 side, and sends this air to the downstream space 1B located on the blower outlet 5 side. More specifically, the blower unit 6 is configured to send out air sucked from the lower suction port 4 toward the upper blower outlet facing portion 3 </ b> A in a state of being arranged below the blower outlet 5. Yes. The blower unit 6 includes an electric fan 7 that sucks and feeds air, and is connected to a power source and a control circuit (not shown). This control circuit is good also as a structure which operates the ventilation unit 6 based on the output of the sensor which detects the cleanliness of air.

  The air cleaning device 8 purifies the air sucked into the blower unit 6 from the suction port 4 side, and is provided between the suction port 4 and the blower unit 6 in the casing 1. The air cleaning device 8 is attached to the upstream side of the fan 7 and is arranged so as not to disturb the flow of air sucked into the fan 7. The air cleaning device 8 includes a discharge electrode 8A for applying a high voltage, two ground electrodes 8B arranged opposite to each other, and a power source (not shown) for applying a high voltage to the discharge electrode 8A. And. The discharge electrode 8A is disposed between two grounded ground electrodes 8B and faces the ground electrodes 8B. In the following description, the discharge electrode 8A and the ground electrode 8B may be referred to as electrodes 8A and 8B.

  When the air cleaning device 8 is operated, if a high voltage is applied between the discharge electrode 8A and the ground electrode 8B by the power source, active oxygen such as ozone is generated between these electrodes 8A and 8B, or a high electric field (high potential difference) is generated. ) Is formed. These active oxygen and high electric field have a function of cleaning air passing between the electrodes 8A and 8B. This action includes the action of inactivating microorganisms such as viruses, fungi, and molds contained in the air to suppress the growth of the microorganisms, the action of collecting the microorganisms, and the action of denaturing the proteins that are allergens. , At least one of the actions of adsorbing and decomposing molecules that become odors is included. Of these functions, what is realized can be selected according to the configuration of the electrodes 8A and 8B, the setting of the power source, and the like. Moreover, if the filter which filters air with the air purifying device 8 is used together, the efficiency which removes microorganisms, fine dust, etc. from air can be improved.

  The air cleaning device 8 has a characteristic that, as the wind speed of the air passing between the electrodes 8A and 8B is lower, the cleaning ability is higher and the pressure loss when the air passes is lower. For this reason, the discharge electrode 8A and the ground electrode 8B are preferably formed in as large an area as possible. In the air cleaning device 8 illustrated in FIG. 1, the longer the ground electrode 8B is in the air flow direction, the larger and more uniform the discharge space between the electrodes 8A and 8B is, and the air is efficiently cleaned. Is done. For this reason, it is preferable to form the ground electrode 8B as long as possible. In this case, if the length direction of the ground electrode 8B is set parallel to the air flow direction, it is possible to suppress the air flow from being disturbed by the ground electrode 8B.

  A suction rear panel 9 is provided on the upstream side of the air cleaning device 8. The suction back panel 9 is formed of, for example, a plate material whose cross section is curved in a J shape or a U shape, and extends in the left-right direction of the air cleaner. The suction back panel 9 is disposed so as to cover the suction port 4 from the rear and to cover the suction side of the blower unit 6 (upstream side of the air cleaning device 8) from below. Thus, the upstream space 1A of the casing 1 is formed as a space surrounded by the front panel 2 (suction port 4), the upstream part of the blower unit 6 (air cleaning device 8), and the suction back panel 9. Yes. And the suction back panel 9 changes the flow direction of the air sucked into the rear upstream space 1A from the suction port 4 upward, and guides the air from the suction port 4 toward the air cleaning device 8. It is configured.

  The air direction control plate 10 corresponds to the air direction control mechanism of the present embodiment, and a plurality of air direction control plates 10 are provided in the air outlet facing portion 3A of the back panel 3 in the casing 1 and are arranged on the downstream side of the air blowing unit 6. The plurality of wind direction control plates 10 guide the air flow sent out from the blower unit 6 toward the air outlet 5 and disperse the air flow throughout the air outlet 5. More specifically, each wind direction control plate 10 is formed of, for example, an elongated plate whose cross section is curved in a J-shape or U-shape, and flows in the left-right direction of the air cleaner, that is, the air flow sent out from the blower unit. It extends in a direction orthogonal to the direction.

  The air direction control plates 10 are arranged in parallel to each other at intervals in the flow direction of the air sent out from the blower unit 6, that is, in the vertical direction of the back panel 3 in FIG. 1, and are distributed over the entire air outlet facing portion 3A. Has been. And each wind direction control board 10 protrudes toward the blower outlet 5 from the blower outlet facing part 3A, and is arrange | positioned so that the concave curved surface which appears in cross-sectional shape may be in the state where it was depressed with respect to the ventilation unit 6. . The total number of the wind direction control plates 10, the position and size of each wind direction control plate 10, and the inclination angle of each wind direction control plate 10 with respect to the back panel 3 are such that the air flow blown out from each part of the blowout port 5 is uniform. Is preferably set so as to be perpendicular to. A specific example of this setting will be described in the second embodiment.

  The air cleaner according to the present embodiment has the above-described configuration, and the operation thereof will be described next. First, at the time of operation of the air cleaner, when the air blowing unit 6 (fan 7) is operated, air is sucked into the upstream space 1A from the suction port 4. This air is introduced between the electrodes 8A and 8B of the air cleaning device 8 by being guided by the suction back panel 9. Then, after being cleaned by passing between these electrodes 8A, 8B, the air is sent from the blower unit 6 to the downstream space 1B via the fan 7.

  At this time, the air sent out from the blower unit 6 is blown to each wind direction control plate 10 provided on the air outlet facing portion 3A of the back panel 3. The air is guided to the plurality of wind direction control plates 10 to change the flow direction of the air toward the air outlet 5 and form an air flow that is uniformly dispersed throughout the air outlet 5. In this state, the air is blown out of the casing 1 from the air outlet 5.

  Thus, in this Embodiment, it is set as the structure which provides the some air direction control board 10 in 3 A of blower outlet facing parts of the back panel 3, and sends air toward the blower facing part 3A by the ventilation unit 6. FIG. As a result, the air direction control plate 10 distributes the air sent out from the blower unit 6 to the entire outlet 5 by the plurality of air direction control plates 10, and changes the air flow direction by the individual air direction control plates 10. Can be changed towards. Therefore, the air flow in which the air volume and the air speed are made uniform can be stably blown out from the entire outlet 5. In particular, since the plurality of wind direction control plates 10 arranged at different positions in the air flow direction are each extended in a direction orthogonal to the air flow direction, the function of each wind direction control plate 10 is Can be exerted stably.

  Moreover, in the present embodiment, since the wind direction control plate 10 that is a plurality of elongated plate members is used as the wind direction control mechanism, the structure of the wind direction control mechanism can be simplified and cost reduction can be promoted. In the present embodiment, a plurality of wind direction control plates 10 are illustrated, but the present invention is not limited to this, and the wind direction control mechanism is an arbitrary one having a function of changing the direction of the wind in the entire air outlet facing portion 3A. It can be constituted by a member.

  Moreover, since the said effect is acquired by the wind direction control board 10, in this Embodiment, the casing 1 is formed thinly in the front-back direction, and the suction inlet 4 and the suction back surface are formed toward the upper side from the lower part side of an air cleaner. It is set as the structure which arrange | positions the panel 9, the air purifying device 8, the ventilation unit 6, the blower outlet 5, and the wind direction control board 10 in order. Thereby, a thin air cleaner with a small installation floor area and good space efficiency can be realized. Moreover, by stabilizing the air flow with the wind direction control plate 10, the opening area of the outlet 5 can be increased, and the pressure loss can be suppressed to improve the operation efficiency.

  Moreover, in this Embodiment, since the suction inlet 4 and the blower outlet 5 are opened to the front panel 2 of the casing 1, when installing an air cleaner indoors, for example, the back panel 3 fits the wall of a house. Can wear. Thereby, an air cleaner can be brought close to the corner of a room and an indoor space can be used effectively. Further, indoor air can be efficiently cleaned in a wide space existing on the front side of the air cleaner.

  Further, the air blowing direction by the blower unit 6 is inclined with respect to the extending direction of the back panel 3 in the vertical direction as indicated by arrows in FIG. The inclination angle in the air blowing direction is set in advance so that the air sent from the air blowing unit 6 hits the air outlet facing portion 3A of the rear panel 3, that is, each air direction control plate 10. Thereby, in this Embodiment, the air sent out from the ventilation unit 6 can be reliably applied to each wind direction control board 10, and the function of the wind direction control board 10 can be exhibited stably.

  Here, if the angle formed by the air sent from the blower unit 6 and the surface of the air outlet facing portion 3A is defined as the air blowing angle, the air sent out faces the air outlet as the air blowing angle increases and becomes closer to a right angle. Since the direction is changed so as to be reflected by hitting the part 3A, the pressure loss is increased at this time, and the blowing efficiency is lowered. On the other hand, when the air blowing angle is small, the delivered air hits a part of the nearest air direction control plate 10 among the air direction control plates 10, and this air changes its direction in a state where the air volume and the air speed are large, and the air outlet Reach 5 As a result, the air blown out from the outlet 5 tends to have a non-uniform wind speed distribution.

  Therefore, the configuration of each wind direction control plate 10 is preferably designed appropriately based on parameters such as the wind speed distribution, the wind direction distribution, and the air volume of air sent from the blower unit 6, for example. More specifically, for example, the number of wind direction control plates 10 arranged on the air outlet facing portion 3A of the rear panel 3, the distance between the air direction control plates 10, the shape of the individual air direction control plates 10, and the air outlet facing portion 3A. The projecting dimensions and the like are appropriately set based on the parameters. FIG. 1 shows an example of such a setting, and does not limit the present invention.

  Moreover, in this invention, you may mount the actuator which can change the ventilation angle when, for example, it blows toward the wind direction control board 10 from the ventilation unit 6. FIG. This actuator, for example, appropriately changes the air blowing angle according to the air velocity distribution, the air volume, etc. of the air blown from the air blowing unit 6, and the air velocity distribution of the air blown out from the air outlet 5 is uniform regardless of the air volume. You may control so that it may become. Thereby, this state can be stably maintained irrespective of an air volume, making the air which blows off from the blower outlet 5 uniform.

  On the other hand, in this Embodiment, as shown in FIG. 1, the case where the suction inlet 4 was arrange | positioned at the lower end part of the casing 1 was illustrated. In this case, for example, a leg portion or the like that supports the lower end portion of the casing 1 in a state of floating from the floor may be provided, and an air flow path may be secured between the lower end portion of the casing 1 and the floor surface. Moreover, in this invention, although the suction inlet 4 may be arrange | positioned in the back part (back panel 3 etc.) of the casing 1, it is set as the structure which inclines the back part of the casing 1 with respect to the wall surface of a house. It is preferable to secure an air flow path between the back surface portion and the wall surface. Thus, if it is set as the structure which uses the inclination of the leg part of the casing 1, and a back part, since pressure loss will reduce when air is sucked in from the suction inlet 4, air can be sucked in efficiently.

  Moreover, in this Embodiment, since the opening area of the blower outlet 5 is set larger than the opening area of the suction inlet 4, the following effects can be acquired. First, according to this setting, the wind speed of the air blown out from the blowout port 5 (blowing wind speed) can be made slower than the wind speed of the air sucked from the suction port 4 (suction wind speed). Thereby, for example, even when the air blowing amount of the air purifier is set to be large, the blown wind speed can be reduced, so that discomfort caused by high-speed wind hitting the user can be suppressed.

  Moreover, pressure loss can be suppressed by lowering the blowing wind speed, thereby reducing noise during blowing and improving blowing efficiency. Furthermore, the visibility of the blower outlet 5 can be improved and the merchantability of an air cleaner can be improved. And even when the opening area of the blower outlet 5 is increased in this way, a uniform air flow can be generated in the entire blower outlet 5 by using the wind direction control plate 10 as described above.

  Moreover, in order to improve the comfort at the time of ventilation, it is preferable to control the blowing air speed by changing the blowing air speed according to, for example, the indoor temperature, humidity, user setting, and the like. Further, for example, the user's comfort can be improved by changing the blowing wind speed like a natural wind. To give a specific example, the wind speed is changed in a cycle in which a long cycle and a short cycle are superposed, or a so-called 1 / f fluctuation of the wind velocity is generated, thereby blowing a comfortable and natural wind to the user. be able to.

  Further, in the present embodiment, the air cleaning device 8 is arranged on the upstream side of the fan 7, and the electrode plates constituting the discharge electrode 8A and the ground electrode 8B are arranged in parallel to the air flow. Thereby, the disturbance of the airflow resulting from the air purification device 8 and the increase in pressure loss can be suppressed. Further, since the air is purified on the upstream side of the fan 7, the occurrence of mold or the like in the fan 7 can be suppressed.

Embodiment 2. FIG.
Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 2 is a perspective view showing a specific configuration example of the wind direction control plate in Embodiment 2 of the present invention, and FIG. 3 is a cross-sectional view of the wind direction control plate shown in FIG. In this specification, the flow direction of air (wind) sent out from the blower unit 6 is expressed as “wind direction”. As described in the first embodiment, the total number of wind direction control plates 10, the position and size of each wind direction control plate 10, and the inclination angle of each wind direction control plate 10 with respect to the back panel 3 blow out from each part of the outlet 5. It is preferable to set so that the air flow is uniform and perpendicular to the air outlet 5. In this embodiment, a specific example of such setting will be exemplified. 2 and 3, a description will be given by taking a flat wind direction control plate 20 as an example instead of the curved wind direction control plate 10 described in the first embodiment.

  A plurality of wind direction control plates 20 are provided on the air outlet facing portion 3A of the back panel 3 in substantially the same manner as in the first embodiment. As shown in FIG. 2, each wind direction control plate 20 is formed of, for example, an elongated rectangular plate material having a long side and a short side. And one long side (base end part) of the long sides of the two sides of the wind direction control plate 20 is fixed to the air outlet facing portion 3A of the back panel 3, and the other long side (tip end portion) faces the air outlet. It is separated from the part 3A. Thereby, the front-end | tip part side of each wind direction control board 20 protrudes so that it may stand | start with respect to 3 A of blower outlet facing parts of the back panel 3. As shown in FIG. In addition, the inclination angle θ of each wind direction control plate 20 is set so as to face the flow of air sent out from the blower unit 6. Here, the inclination angle θ is an angle formed by the air outlet facing portion 3A of the rear panel 3 and the wind direction control plate 20 as described above.

  Further, the short side length L and the inclination angle θ of each wind direction control plate 20 may be set to different dimensions for each individual wind direction control plate 20, as shown in FIG. If a specific example is given, the length L of the short side which is the length from the base end part of the wind direction control board 20 to the front-end | tip part will be formed so that the wind direction control board 20 which is separated from the ventilation unit 6 may become large. . In addition, the inclination angle θ is formed so as to be smaller as the wind direction control plate 20 is farther away from the blower unit 6. Thus, at a position close to the blower unit 6, that is, at a position where the wind speed and the amount of wind received from the blower unit 6 are large, the short side of the wind direction control plate 20 is shortened compared to the position away from the blower unit 6. The inclination angle θ can be increased. Accordingly, it is possible to suppress the wind speed and air volume of the wind that hits the wind direction control plate 20 and changes its direction toward the air outlet 5.

  On the other hand, at a position away from the blower unit 6, that is, at a position where the wind speed and volume of the wind received from the blower unit 6 are small, the short side of the wind direction control plate 20 can be lengthened and the inclination angle θ can be reduced. As a result, it is possible to ensure the maximum wind speed and air volume of the wind that hits the wind direction control plate 20 and changes its direction toward the outlet 5. Therefore, the wind speed and the amount of wind reaching the outlet 5 can be made uniform from a position close to the blower unit 6 to a position away from the blower unit 6 by changing the direction against the individual wind direction control plates 20.

  Next, with reference to FIG. 4, the structure of the wind direction control board 10 by the said Embodiment 1 is demonstrated concretely. FIG. 4 is a cross-sectional view illustrating the length of the short side and the radius of curvature of the wind direction control plate according to the first embodiment. As shown in this figure, the wind direction control plate 10 is formed such that a fracture surface parallel to the short side has a curved shape, and is disposed in a concave shape with respect to the blower unit 6. Moreover, one long side (base end part) of the two long sides of the wind direction control plate 10 is fixed to the air outlet facing part 3A of the back panel 3, and the other long side (front end part) faces the air outlet. It is separated from the part 3A.

  Thereby, the front-end | tip part side of each wind direction control board 10 protrudes so that it may stand | start with respect to 3 A of blower outlet facing parts of the back panel 3. As shown in FIG. Further, the radius of curvature r and the length L ′ of the short side of the concave curved surface of each wind direction control plate 10 are formed to be larger as the wind direction control plate 10 is farther away from the blower unit 6. Here, the short side length L ′ of the wind direction control plate 10 is the distance from the base end portion to the tip end portion of the wind direction control plate 10 in the sectional view shown in FIG. This corresponds to the dimension measured along the line.

  The same effect as that of the wind direction control plate 20 can be obtained by the wind direction control plate 10 configured as described above. That is, at a position close to the blower unit 6, it is possible to suppress the wind speed and the air volume of the wind that hits the wind direction control plate 10 and changes its direction toward the blower outlet 5. Further, at a position away from the blower unit 6, the wind speed and the air volume of the wind that strikes the wind direction control plate 10 and changes its direction toward the outlet 5 can be ensured to the maximum. Accordingly, in the first embodiment, the wind speed and the amount of wind reaching the outlet 5 are made uniform from a position close to the blower unit 6 to a position away from the blower unit 6 by changing the direction against the individual wind direction control plates 10. can do.

Embodiment 3 FIG.
Next, a third embodiment of the present invention will be described with reference to FIG. FIG. 5 is a perspective view showing a specific configuration example of the wind direction control plate in Embodiment 3 of the present invention. As shown in this figure, the air purifier according to the present embodiment includes a plurality of wind direction control plates 31 between the left and right side panels 30 constituting the side part of the casing 1. These wind direction control plates 31 are made of, for example, a flat plate material whose width in the left-right direction is smaller than the interval between the side panels 30. Each wind direction control plate 31 is configured in the same manner as the above-described wind direction control plate 20 except for the width dimension.

  Each wind direction control plate 31 is divided into a plurality of wind direction control plate groups 32 and 33 having different distances from the blower unit 6. The first wind direction control plate group 32 is composed of, for example, three wind direction control plates 31, and these wind direction control plates 31 are along a straight line X <b> 1 orthogonal to the flow direction of the air sent from the blower unit 6. The positions, that is, the positions where the distances from the blower unit 6 are equal to each other are fixed, and a gap S is provided between each wind direction control plate 31. On the other hand, the second wind direction control plate group 33 is composed of, for example, three wind direction control plates 31. These wind direction control plates 31 are arranged along a straight line X2 parallel to the straight line X1, and each of the wind direction control plates 31 is arranged. A gap is provided between 31. The second wind direction control plate group 33 is provided at a position away from the first wind direction control plate group 32 with respect to the blower unit 6.

These wind direction control plates 40, 41 are used for the air sent out from the blower unit 6. They are arranged at different positions in the flow direction.

  Specifically, one wind direction control plate 40 is configured in the same manner as the wind direction control plate 10 described in the first embodiment, for example, and is fixed to the air outlet facing portion 3A of the back panel 3. On the other hand, the other wind direction control plate 41 has the same shape as the wind direction control plate 10, but is disposed on the upstream side of the wind direction control plate 40 as viewed from the blower unit 6. The other air direction control plate 41 is fixed to the side panel 30 at both left and right ends, and is provided on the air outlet facing portion 3 </ b> A via the side panel 30. The other wind direction control plate 41 is supported by the side panel 30 at a position floating from the air outlet facing portion 3A, and a gap S 'is formed between the air direction control plate 41 and the air outlet facing portion 3A. Yes. Due to this gap S ′, the air direction control plates 40 and 41 are arranged so as not to overlap each other when viewed from the air blowing unit 6.

  In the present embodiment configured as described above, it is possible to obtain substantially the same operational effects as those of the third embodiment. That is, the air sent out from the blower unit 6 strikes the wind direction control plate 41 and also strikes the wind direction control plate 40 via the gap S ′. Therefore, air can be applied to the plurality of wind direction control plates 40 and 41 regardless of the shape of the wind direction control plates 40 and 41, and the wind reaching the outlet 5 after hitting the individual wind direction control plates 40 and 41. The air speed and the air volume can be made uniform from a position close to the air blowing unit 6 to a position away from the air blowing unit 6.

  In the fourth embodiment, the case where the two wind direction control plates 40 and 41 are provided is illustrated. However, the present invention is not limited to this, and three or more wind direction control plates may be provided. In this case, what is necessary is just to comprise so that the separation distance from 3 A of blower outlet facing parts of the back panel 3 may differ for every wind direction control board, for example.

Embodiment 5. FIG.
Next, a fifth embodiment of the present invention will be described with reference to FIGS. FIG. 7 is a perspective view showing a part of the air cleaner in Embodiment 4 of the present invention, and FIG. 8 is a cross-sectional view of the wind direction control plate shown in FIG. FIG. 7 shows only two of the wind direction control plates shown in FIG. As shown in these drawings, the air cleaner according to the present embodiment includes, for example, three wind direction control plates 50, 51, 52.

  The wind direction control plates 50, 51, 52 have substantially the same shape as the wind direction control plate 10 described in the first embodiment, and the left and right ends are fixed to the side panel 30 with the side panel 30 interposed therebetween. It is provided in the blower outlet facing portion 3A. Further, at least the wind direction control plates 50 and 51 are supported by the side panel 30 at a position floating from the air outlet facing portion 3A, and a gap is formed between the air direction control plates 50 and 51 and the air outlet facing portion 3A. Has been. This gap is set to become smaller as the distance from the blower unit 6 increases. In addition, each air direction control plate 50, 51, 52 is fixed in contact with the air outlet 5. In other words, the lengths of the short sides of the wind direction control plates 50, 51, 52 are formed so as to increase with distance from the blower unit 6, as in the first embodiment.

  In the present embodiment configured as described above, substantially the same operational effects as those of the fourth embodiment can be obtained. In addition, in the present embodiment, the air direction control plates 50 and 51 are provided at positions where they come into contact with the air outlet 5 in a state of floating from the air outlet facing portion 3A. In addition to hitting the wind direction control plates 50 and 51, it can also hit the wind direction control plate 52 via a gap between the wind direction control plates 50 and 51 and the air outlet facing portion 3A.

  Moreover, since the wind direction control plates 50, 51, and 52 are fixed in contact with the air outlet 5, for example, the air hitting the wind direction control plates 50, 51, and 52 is short compared to the first embodiment. The air outlet 5 can be reached only by moving the distance. As a result, it is possible to make the air velocity and the air volume of the air uniform from a position close to the blower unit 6 to a position away from the air while suppressing disturbance of the air blown out from the blowout port 5.

Embodiment 6 FIG.
Next, a sixth embodiment of the present invention will be described with reference to FIG. 9 and FIG. FIG. 9 is a longitudinal sectional view showing an air cleaner according to Embodiment 6 of the present invention. FIG. 10 is an enlarged cross-sectional view schematically showing the wind direction control plate, the light source, etc. in FIG. As shown in these drawings, the air purifier according to the present embodiment includes a photocatalyst 60 provided on each wind direction control plate 10 and a light source 61.

  For example, the photocatalyst 60 is provided as a film on the surface side of the airflow direction control plate 10 facing the blower unit 6 and has a function of purifying air by receiving light irradiation. More specifically, the photocatalyst 60 generates inactive species such as radicals under light irradiation, thereby inactivating microorganisms in contact with the surface of the wind direction control plate 10, decomposing organic matter, oxidizing nitric oxide, and the like. Execute. As a result, air can be cleaned by the photocatalyst 60.

  The light source 61 irradiates the photocatalyst 60 of each wind direction control plate 10 with light to activate the photocatalyst 60. The light source 61 is disposed in the downstream space 1 B of the casing 1, that is, in the downstream space 1 B of the casing 1. The photocatalyst 60 and the light source 61 constitute an auxiliary cleaning device in the present embodiment. Accordingly, as in the present embodiment, the photocatalyst 60 is installed or applied on the surface of the wind direction control plate 10, or the wind direction control plate 10 is formed using a material containing the photocatalyst 60, so that a single photocatalyst filter or the like can be obtained. An auxiliary cleaning device can be added to the downstream side of the blower unit 6 without being installed. Thereby, the air purification capability can be enhanced without complicating the structure of the air cleaner.

  Further, by configuring the auxiliary cleaning device with the photocatalyst 60 and the light source 61, the pressure loss of the air cleaning device 8 can be made larger than the pressure loss of the auxiliary cleaning device. Thereby, since the pressure loss at the suction port 4 side becomes relatively small, air can be sucked in efficiently. Further, in the present embodiment, as shown in FIG. 10, the position and size of each wind direction control plate 10 are set so that the individual wind direction control plates 10 do not overlap each other when viewed from the light source 61. Thereby, since the light irradiated from the light source 61 can be efficiently irradiated to the entire wind direction control plate 10, that is, the entire photocatalyst 60, the light of the light source 61 can be effectively used, The air purification capability of the photocatalyst 60 can be maximized.

  Moreover, according to this Embodiment, it can comprise so that the light of the light source 61 may be reflected in each wind direction control board 10, and may leak outside from the blower outlet 5. FIG. Thereby, for example, the user can be notified that the air cleaner is in operation, and the design of the air cleaner can be improved. If the light from the light source 61 contains harmful ultraviolet rays or the like, for example, a material such as a phosphor that absorbs ultraviolet rays and reflects visible light is mixed in the photocatalyst 60 to avoid leakage of ultraviolet rays to the outside. can do. In this case, it is preferable to appropriately set the position of the light source 61 so that the light from the light source 61 does not leak directly to the outside. Further, as the photocatalyst 60, there is a photocatalyst that exhibits a catalytic function with visible light, and therefore a light source having an appropriate wavelength may be used depending on the material of the photocatalyst 60.

  In the present invention, the color of the light source 61 may be changed based on various parameters. Examples of parameters include the operating state of the blower unit 6 (for example, wind speed, air volume, etc.), detection results of pollutants by a pollutant sensor (not shown), temperature and humidity, time, presence of people around the air cleaner, etc. Is mentioned. Moreover, it is good also as a structure which changes the color of the light source 61 by a user setting. According to this configuration, the operating state of the air cleaner can be notified to the user by the color of the light source 61, and the merchantability can be enhanced by the color effect. In particular, since the air purifier according to Embodiments 1 to 6 has a large opening area of the air outlet 5, the light emission state of the light source 61 is highly visible even at a position relatively far from the air purifier. The influence on the design is also great. Therefore, if it is set as the structure which changes the color of the light source 61, the alerting effect to a user and the effect effect of a color can be exhibited notably using the big blower outlet 5. FIG.

Embodiment 7 FIG.
Next, a seventh embodiment of the present invention will be described with reference to FIG. 11 and FIG. FIG. 11 is a longitudinal sectional view showing a state in which the air cleaner is normally operated in Embodiment 7 of the present invention. FIG. 12 is a longitudinal sectional view showing a state in which the air cleaner in FIG. As shown in these drawings, the air purifier according to the present embodiment is configured in substantially the same manner as the air purifier described in the first embodiment, but the blower unit 70 capable of changing the assembly state; And a wind direction control plate 71 constituting a wind direction control mechanism.

  As in the first embodiment, the blower unit 70 is mounted with the fan 7 and the air purifying device 8, but the blower unit 70 has two normal assembly states and reverse assembly states with respect to the casing 1. It can be assembled in the assembled state. Here, the normal assembly state is an assembly state in which the air blowing unit 70 blows air from the suction port 4 toward the air outlet 5 as in the first embodiment (see FIG. 11). On the other hand, the reversely assembled state is an assembled state in which air is blown in the reverse direction from the outlet 5 toward the inlet 4 as shown in FIG.

  If an example of the structure which can change an assembly state in this way is given, the ventilation unit 70 is rotatably supported by the side panel of the casing 1 via the support shaft which is not shown in figure. The user can easily change the assembled state of the blower unit 70 between the normal assembled state and the reversely assembled state by rotating the blower unit 70 around the support shaft.

  When the air cleaner is operated in a normal assembly state (normal operation), the air sucked into the blower unit 70 from the suction port 4 passes through the air cleaning device 8 and the fan 7 to the wind direction control plate 71 in order. To reach. The direction of the air is changed by the wind direction control plate 71 and blows out from the air outlet 5 to the outside. On the other hand, when the air purifier is operated in the reverse orientation (backward operation), the air flowing into the casing 1 from the blowout port 5 is changed in direction by the wind direction control plate 71 and sucked into the blower unit 70. It is. This air is sent out from the blower unit 70 via the air cleaning device 8 and the fan 7 in order, guided to the suction back panel 9 and blown out from the back outlet 73. In addition, the back surface outlet 73 is provided in the lower end part of the back panel 3, for example.

  According to this Embodiment comprised in this way, according to the use environment etc. of an air cleaner, the air blower outlet can be properly used between the front blower outlet 5 and the back blower outlet 73. FIG. That is, for example, at the time when pollen is scattered, the air outlet 5 of the air cleaner assembled in the reverse assembly state is arranged facing out of the window, and the air cleaner is operated in the reverse wind in this state. After the outside air containing pollen is cleaned, it can be taken into the room through the rear outlet 73. Therefore, the air outlet of the air purifier can be changed according to the use, and the change operation can be performed without changing the rotation direction of the fan 7 or performing a large-scale switching operation. It can be done easily just by changing. For this reason, according to this Embodiment, in addition to the effect similar to the said Embodiment 1, a user's convenience can be improved.

  In addition, in the said Embodiment 7, although the case where the assembly | attachment state of the ventilation unit 70 was changed was illustrated, this invention changes the position, direction, etc. of the suction back panel 9 and the wind direction control board 71 in addition to this. It is good also as a structure. Moreover, it is preferable to adjust appropriately the position and direction of the wind direction control board 71 so that smooth ventilation becomes possible irrespective of a wind direction.

  In the first to seventh embodiments, the individual configurations are illustrated, but the present invention is not limited to these individual configurations. That is, in the present invention, for example, a single air cleaner may be realized by combining a plurality of configurations that can be combined among the first to seventh embodiments.
