Description

  The present invention relates to a deodorizer using an ozone generator that deodorizes air.

  2. Description of the Related Art Conventionally, a deodorizing machine that deodorizes air existing in a closed space such as a room or a car with ozone discharged from an ozone generator has been used. As this type of deodorizer, there is known an automobile deodorizer including an ozone generator and a centrifugal fan in a housing in which an inlet and an outlet are formed (for example, see Patent Document 1). In this deodorizer for automobiles, the ozone generator is arranged upstream and in the center of the centrifugal fan, so the ozone discharged from the ozone generator and the air sucked from the suction port are efficiently mixed by the centrifugal fan. be able to.

  However, since this automobile deodorizer mixes ozone and air with a centrifugal fan, the distance from the ozone generator to the outlet must be secured in the centrifugal direction of the centrifugal fan, and a large housing is required. I was trying. If the distance from the ozone generator to the air outlet is shortened, the housing can be downsized, but if the distance from the ozone generator to the air outlet is shortened, ozone can be sufficiently mixed with air and diluted and diffused. However, there was a problem that the ozone concentration at the outlet became high.

JP-A-8-253025

  An object of this invention is to provide the deodorizer which can reduce the ozone concentration in a blower outlet even if the distance from an ozone generator to a blower outlet becomes short in view of the said problem.

  In order to solve the above problems, a deodorizer according to the present invention includes a cylindrical casing having a suction port, a blower outlet, and a blower passage connecting the suction port and the blower outlet, and an ozone generator and a blower are provided inside the casing. The fan is disposed along the axial direction of the columnar space covered with the casing, and includes a disk-shaped diffusion means for diffusing ozone released from the ozone generator, and the diffusion means generates ozone. It is arrange | positioned along the said axial direction between a container and a ventilation fan, It is characterized by the above-mentioned.

  According to the deodorizer of the present invention, since the air flowing from the suction port by the rotation of the blower fan and flowing around the outer periphery of the diffusing means generates an air flow from the center of the diffusing means toward the outer periphery, the ozone generator The released ozone can be diffused by the diffusing means, and the diffused ozone can be diluted by mixing with air flowing from the center of the diffusing means toward the outer periphery. Therefore, even if the distance from the ozone generator to the air outlet is short, the ozone concentration at the air outlet can be reduced. Further, since the diffusing means is coaxially disposed on the ozone generator and the blower fan, high-concentration ozone is not directly applied to the fan blade of the blower fan. Therefore, even if the fan blade of the blower fan is formed of a resin material. Deterioration due to ozone can be prevented.

  As shown in FIGS. 3 and 4, the housing 10 is provided with an air passage 104 that connects the first suction port 102 a and the air outlet 103 b. In the air passage 104, the dust collection filter 20 is disposed between the side panel 102 and the casing 101, and between the casing 101 and the top panel 103, the lower part inside the casing 101 moves from the upper part to the upper part. The deodorizing unit 30, the ozone generator 40, the diffusion plate 50 (diffusion means), and the blower fan 60 are arranged in this order. As shown in FIG. 3, the deodorizing unit 30, the diffusion plate 50, and the blower fan 60 are formed in a columnar space formed inside the cylindrical casing 101 (the upper side is the air passage 104 and the lower side is the substrate housing chamber 70). (Space) along the axis O. Moreover, the ozone generator 40 is arrange | positioned along the axis line O so that it may not overlap with the axial direction with respect to the heater 30b mentioned later, as shown in FIG. Further, inside the casing 101, a substrate accommodation chamber 70 in which the power supply substrate 701 and the ozonizer substrate 702 are accommodated is disposed in the lower portion of the casing 101 which is a lower portion of the air passage 104 and is partitioned from the air passage 104. . The deodorizing unit 30 includes a catalyst filter 30a that adsorbs and decomposes odor components, a heater 30b that promotes decomposition of the adsorbed odor components by heating the catalyst filter 30a, and a holder that holds the catalyst filter 30a and the heater 30b. 30c. As described above, the deodorizer 1 includes the deodorization unit 30 in the present embodiment, but the present invention is not limited to this, and may be a deodorizer that does not include the deodorization unit 30, for example.

  The second suction port 101a formed in the casing 101 is disposed below the deodorizing unit 30, and the third suction port 101b formed in the casing 101 is a position between the blower fan 60 and the deodorizing unit 30, and It is arranged below the diffusion plate 50. In the deodorizer 1, the air present in the vehicle sucked from the first suction port 102 a by the rotation of the blower fan 60 is discharged from the catalyst filter 30 a and the ozone generator 40 of the deodorization unit 30 while being discharged from the blower outlet 103 b. It has a structure in which air is deodorized by the generated ozone or ozone alone.

  The dust collection filter 20 is formed by forming a nonwoven fabric or the like into a pleated shape, and collects dust, pollen, etc. contained in the air present in the vehicle sucked from the first suction port 102a.

  The catalyst filter 30a is a honeycomb core board having air permeability formed by taking a honeycomb structure into a core part and having a plate shape. Here, the catalyst filter 30a is made of an aluminum alloy and has a metal oxide such as manganese oxide on its surface. A catalyst of a noble metal such as platinum or platinum is formed to a predetermined thickness (catalyst layer). Further, as the adsorbent, it is preferable to further add various ceramic powders that are inorganic adsorbents. The catalyst filter 30a only needs to have a structure (heating regeneration type) that can promote the decomposition of the adsorbed odor component by heating, and may be a catalyst filter having another heating regeneration structure. The heater 30b is a plate-like PTC heater that controls its own temperature by utilizing the characteristic that the electric resistance value increases as the temperature rises. The heater 30b is disposed at the center of the catalyst filter 30a, and the heat of the PTC heater is reduced to the catalyst filter 33. Then, the catalyst filter 33 is heated. The holder 30 c is formed in a cylindrical shape with an elastic resin material such as silicon rubber so as to cover the periphery of the catalyst filter 30 a and is supported by the casing 101.

  The ozone generator 40 is an ozonizer that is formed in a rectangular tube shape with an ozone-resistant resin material, and sterilizes and deodorizes air by discharging the generated ozone from the discharge port 40a. Ozone is generated by discharging the air sucked from the suction port 101a and the third suction port 101b. The ozone generator 40 is fixed to the lower surface of a diffusion plate 50 described later, and is disposed so that the ozone discharge port 40 a faces the center of the diffusion plate 50. Moreover, although the ozone generator 40 and the heater 30b are arrange | positioned along the axial direction, the ozone generator 40 is arrange | positioned in the position which does not overlap with an axial direction with respect to the heater 30b. Accordingly, since the ozone generator 40 and the heater 30b do not face each other in the axial direction, the influence of heat on the ozone generator 40 when the heater 30b generates heat (for example, expansion and contraction of the ozone generator 40) is suppressed. This prevents the ozone generator 40 from deteriorating. Furthermore, the ozone generator 40 has an electrode socket 40c formed on a side surface 40b thereof, and a second cable 702a described later is connected thereto. The electrode socket 40c is formed on the side surface 40b of the ozone generator 40, so that an insulation distance from the metal catalyst filter 30a is maintained, and discharge between the electrode socket 40c and the catalyst filter 30a is prevented.

And have. The diffusion plate 50 is formed of an ozone resistant resin material such as PC (polycarbonate) or PP (polypropylene) and a heat resistant resin material. The diffusion plate 50 functions as an ozone diffusion means for diffusing ozone emitted from the ozone generator 40 and diluting ozone. The diffusing surface 50 d of the diffusing plate 50 is set such that the diameter dimension “a” thereof is equal to the diameter dimension “b” of a boss 60 a described later included in the blower fan 60. The diffusion plate 50 is locked to the casing 101 by two first extension pieces 50a extending radially from the diffusion surface 50d. As shown in FIG. 5, the first extension piece 50 a is formed so as to be erected with respect to the diffusion surface 50 d, and the first extension piece 50 a that extends radially is locked at the tip of the casing 101. A nail 50a1 is formed. Further, as shown in FIG. 4, in the diffusion plate 50, the ozone generator 40 is fixed to the second extension piece 50 b extending radially from the diffusion surface 50 d. As shown in FIG. 5, the second extension piece 50b is formed so as to be erected with respect to the diffusion surface 50d, and a fixing claw 50b1 for fixing the ozone generator 40 is formed on the center side of the diffusion surface 50d.

Is formed.

  As shown in FIGS. 2 to 4, the blower fan 60 is an axial fan that blows air in the rotation axis direction (the direction of the axis O), and is a fan that can be installed in the casing 101. The blower fan 60 has a built-in fan motor (not shown), and has a cylindrical boss 60a connected to the rotating shaft of the fan motor and a plurality of pieces (for example, five pieces) integrally formed on the outer periphery of the boss 60a. ) Fan blade 60b, a fan motor (not shown), a boss 60a, and a fan case 60c that houses the fan blade 60b. The fan case 60c is formed of a synthetic resin in a square cylinder shape so as to surround the plurality of fan blades 60b, and the corner portion 60c1 of the fan case 60c is supported by the casing 101.

  As shown in FIG. 4, the control board 70 includes a power supply board 701 and an ozonizer board 702. The power board 701 is supplied with power from a cigar socket installed in the vehicle through a power cord 701a. The power supply board 701 supplies power to the operation unit 103a through the first cable 701b and receives an operation signal from the operation unit 103a, and supplies power to the blower fan 60 and transmits a control signal through the cable (not shown). This is a substrate that controls the driving of the blower fan 60. Further, the power supply board 701 supplies power to the heater 30b through a cable (not shown) to control the operation of the heater 30b, and supplies power to the ozonizer board 702 through a cable (not shown). The ozonizer substrate 702 is a substrate that supplies power to the ozone generator 40 through the second cable 702a.

  As shown in FIG. 3, the deodorizer 1 according to the present embodiment configured as described above has the air (arrow A) sucked from the first suction port 102 a of the side panel 102 by the rotation of the blower fan 60. Dust is removed through the dust collection filter 20 and is sucked into the second suction port 101 a and the third suction port 101 b of the casing 101. The air (arrow B) sucked from the second suction port 101a of the casing 101 was subjected to a deodorizing process in which odorous components such as ammonia and methyl mercaptan and harmful components such as formaldehyde were removed by the catalyst filter 30a of the deodorizing unit 30. Thereafter, the air is blown to the upper air passage 104. The air (arrow C) from which odor components and harmful components have been removed through the second suction port 101a of the casing 101 and the air (arrow D) sucked from the third suction port 101b of the casing 101 are the ozone generator 40. The sterilization and deodorization treatment is performed by ozone released from

  Here, the flow of air for diffusing ozone released from the ozone generator 40 by the diffusion plate 50 will be described. The air (arrow C) from which the odor components and harmful components have been removed by the rotation of the blower fan 60 and removed from the second suction port 101a and the air (arrow D) sucked from the third suction port 101b are sent to the blower fan 60. It flows on the outer periphery of the diffusing surface 50d set to a diameter dimension a equivalent to the diameter dimension b of the boss 60a.

  As a result, air (arrow C) from the second suction port 101a that has flowed around the outer periphery of the diffusion surface 50d and from which odor components and harmful components have been removed, and air that has been sucked from the third suction port 101b (arrow D) Thus, air (arrow E) that flows radially from the center of the diffusing face plate 50d toward the entire outer periphery is generated. Accordingly, the ozone released from the ozone generator 40 rides on the radially flowing air (arrow E) and is diffused radially. Since ozone is diffused radially along the diffusion plate 50, the concentration of ozone released from the ozone generator 40 immediately decreases. The ozone diffused by the diffusion plate 50 is equivalent to air (arrow C) from which the odor components and harmful components are removed by being sucked from the second suction port 101a and air (arrow D) from which the third suction port 101b is sucked. To be diluted. Thus, the air (arrow F) deodorized by the catalyst and ozone, which is sucked from the second suction port 101a and the third suction port 101b, passes through the opening 101c of the casing 101 from the outlet 103b of the top panel 103. Released into the car.

  As described above, according to the deodorizer 1 in the present embodiment, a cylindrical casing having the second suction port 101a, the blower outlet 103b, the third suction port 101b, and the blower passage 104 connecting the blower outlet 103b. 101, an ozone generator 40 and a blower fan 60 are coaxially arranged inside the casing 101, and a disc-shaped diffusion plate for diffusing ozone emitted from the ozone generator 40 50 and the diffusion plate 50 is disposed coaxially between the ozone generator 40 and the blower fan 60. The second suction port 101a and the third suction port 101b are formed over the entire circumference of the casing 101 in the circumferential direction.

  As a result, the entire outer periphery from the center of the diffusion plate 50 by the air (arrows D and F) sucked from the second suction port 101a by the rotation of the blower fan 60 and flowing in the outer peripheral side of the diffusion surface 50d in the axial direction. As a result, an air flow (arrow E) is generated, so that the ozone released from the ozone generator 40 can be immediately diffused and diluted by the diffusion plate 50 toward the entire outer periphery. Therefore, even if the distance from the ozone generator 40 to the outlet 103b is short, the ozone concentration at the outlet 103b can be reduced. Further, since the diffusion plate 50 is coaxially disposed on the ozone generator 40 and the blower fan 60, high-concentration ozone is not directly applied to the fan blade 60b of the blower fan 60. Even if it is formed of a resin material, deterioration due to ozone can be prevented.

  Moreover, according to the deodorizer 1 in this embodiment, since the ventilation fan 60 is an axial fan, the casing 101 can be reduced in size and even if the number of fan blades 60b is small as in the axial fan. The ozone released from the ozone generator 40 can be efficiently mixed with the air (arrow D) sucked from the third suction port 101b.

  Further, according to the deodorizer 1 in the present embodiment, the blower fan 60 has the cylindrical boss 60a, the fan blade 60b is integrally formed on the outer periphery of the boss 60a, and the diameter a of the diffusion surface 50d is the diameter of the boss 60a. Since the size is equal to the size, the diffusion plate 50 can be prevented from obstructing the air blowing by the blower fan 60 while keeping the ozone diffusion effect by the diffusion plate 50 good.

  In addition, according to the deodorizer 1 in the present embodiment, the catalyst filter 30a that adsorbs and decomposes the odor component at the lower portion of the ozone generator 40 and the heater 30b that heats the catalyst filter 30a and accelerates the decomposition of the odor component are coaxial. The diffusion plate 50 is made of a heat resistant resin material.

  Thereby, in addition to the deodorizing process by the ozone discharged from the ozone generator 40, the deodorizing process by the catalyst of the catalyst filter 30a is performed, so that the deodorizing performance of the deodorizer 1 can be enhanced. Moreover, since the diffusion surface 50d can insulate the heat of the heater 30b, the expansion and contraction of the blower fan 60 due to the heat of the heater 30b can be suppressed and deterioration of the blower fan 60 can be prevented.

  Furthermore, according to the deodorizer 1 in this embodiment, since the ozone generator 40 is disposed at a position that does not overlap the heater 30b in the axial direction, the ozone generator 40 expands and contracts due to the heat of the heater 30b. It can suppress and the deterioration of the ozone generator 40 can be prevented.

  In addition, in the deodorizer 1 in this embodiment, the diffusion surface 50d is formed in a disk shape having a flat surface. However, the present invention is not limited to this, and the air diffusion port 50b extends from the central portion toward the outer periphery. It may be formed in a mortar shape that is gradually bent in the direction, and can be appropriately modified to increase the diffusion efficiency of ozone.
