Description

  The present invention relates to a deodorizing device.

  2. Description of the Related Art A deodorizing device is known which is attached to an air outlet of an air conditioner installed in a room of a house or in a vehicle. This type of deodorizing device is attached to, for example, a fin provided at an air outlet of an air conditioner. Then, the air blown out from the air conditioner passes through the deodorizing device, so that the air is deodorized and the fragrance is sprayed on the air (for example, see Patent Document 1).

  For deodorization by a conventional deodorizing device, for example, a material such as activated carbon that adsorbs odor components contained in the air, or a paste-like material containing a component that chemically reacts with the odor components is used. However, after adsorbing a certain amount of odor components or chemically reacting with a certain amount of odor components, the above-mentioned materials cannot remove odor components in the air. Therefore, in order to continuously deodorize the air, it is necessary to periodically replace the deodorizing device.

  On the other hand, the photocatalyst decomposes odor components in the air when exposed to light. In addition, unlike activated carbon, which adsorbs the causative substance, the effect is maintained only by irradiating light. Therefore, by using a photocatalyst in the deodorizing device, it is possible to continuously remove odor components.

JP-A-2006-131946

  A deodorizer using a photocatalyst can permanently deodorize air by washing dust accumulated on the surface of the photocatalyst with running water or the like. However, in a deodorizing device provided with a light source for illuminating the photocatalyst, when the photocatalyst is washed with tap water or the like, it is necessary to remove the deodorizing device itself from the air conditioner and disassemble the photocatalyst and the light source.

  The present invention has been made under the above circumstances, and an object of the present invention is to provide a deodorizing device capable of easily cleaning a photocatalyst.

  In order to solve the above problems, a deodorizing device according to the present embodiment is provided at a blowout port or a suction port of a blower, a casing provided with a passage through which air from the blowout port or air to the suction port is provided, and a casing. A sheet to which a photocatalyst is added, a light source for illuminating the sheet, which is provided in the casing, and a support for detachably supporting the casing and the sheet, which are detachably attached to the outlet or the suction port.

  Hereinafter, the present embodiment will be described with reference to the drawings. In the description, an XYZ coordinate system including an X-axis, a Y-axis, and a Z-axis orthogonal to each other is appropriately used.

  FIG. 1 is a perspective view of a deodorizing device 10 according to the present embodiment. The deodorizing device 10 is a device that decomposes a substance harmful to the human body and a substance causing odor using a photocatalyst. As shown in FIG. 1, the deodorizing device 10 includes a blowing unit 20 and a deodorizing unit 30 attached to the blowing unit 20.

  FIG. 2 is a perspective view of the blower unit 20. The blower unit 20 is a unit having a fan rotated by, for example, a motor. As shown in FIG. 2, the blower unit 20 includes a housing 21 having an air outlet 21a formed therein, and a motor and a fan disposed inside the housing 21.

  The housing 21 is a hollow member having a substantially square shape, and has an outlet 21a formed on the surface (the surface on the −Y side) communicating with the internal space. The outlet 21a is composed of a plurality of slits whose longitudinal direction is in the X-axis direction. Further, although not shown in FIG. 2, an air inlet configured substantially in the same manner as the air outlet 21 a is provided on the rear surface (the surface on the + Y side) of the housing 21.

  On the −Y side surface of the housing 21, a pair of projecting portions 21 b projecting toward the −Y side is formed so as to sandwich the outlet 21 a. An extension 21c extending in the + Y direction is formed at the lower end of the housing 21. The lower surface of the extension 21c is a flat surface parallel to the XY plane. The housing 21 is self-supported by the extension 21c in a state of being tilted about 20 degrees with respect to the XZ plane.

  In the blower unit 20 configured as described above, when electric power is externally supplied to the motor housed in the housing 21, the blower fan housed inside the housing 21 rotates. As a result, air is blown out from the outlet 21a of the housing 21.

  FIG. 3 is a perspective view of the deodorizing unit 30. The deodorizing unit 30 is a unit that removes odor components contained in the air blown out from the blowing unit 20. FIG. 4 is a developed perspective view of the deodorizing unit 30. As shown in FIG. 4, the deodorizing unit 30 has a rectangular frame 40 whose longitudinal direction is the X-axis direction, and a deodorizing mechanism 50 mounted on the frame 40.

  The frame 40 is made of a resin such as plastic, for example, and has three openings 40a. The opening 40a is an opening that penetrates the frame 40 in the Y-axis direction with the longitudinal direction as the X-axis direction. The opening 40a functions as an air passage. At both ends in the X-axis direction of the frame 40, a pair of concave portions 40b whose longitudinal direction is the Z-axis direction is formed. The pair of recesses 40b communicates with the three openings 40a via rectangular slits 40d whose longitudinal direction is the Y-axis direction. Further, a rectangular notch 40c communicating with the concave portion 40b is formed on each side surface of the frame 40 in the X-axis direction.

  FIG. 5 is a diagram showing an AA cross section of the frame 40 in FIG. As shown in FIG. 5, the concave portion 40b and the slit 40d are formed from the −Y side surface of the frame 40 to the vicinity of the + Y side surface. The size of the concave portion 40b and the slit 40d in the Y-axis direction are equal. The notch 40c is formed from the −Y side surface of the frame 40 to the + Y side surface. The size of the notch 40c in the Y-axis direction is about half the size of the recess 40b and the slit 40d in the Y-axis direction.

  In the frame 40, the inside of the partition 40f located between the outer periphery 40e on the + Z side and the -Z side of the opening 40a and the opening 40a is hollow. The substrate 42 is accommodated inside the two outer peripheral portions 40e and the two partition portions 40f.

  FIG. 6 is a perspective view of the substrate 42. As shown in FIG. 6, it is shaped into a rectangle whose longitudinal direction is the X-axis direction. The board 42 is, for example, a rigid wiring board formed by impregnating glass fiber with an epoxy resin. A circuit pattern is formed on the surface of the substrate 42, and a light emitting diode 42a is mounted. On the substrate 42, three light emitting diodes 42a are arranged on one surface at equal intervals in the X-axis direction. The light-emitting diode 42 a is a square plate-shaped LED chip, and emits blue light including ultraviolet light in a direction orthogonal to the substrate 42.

  As shown in FIG. 5, a light emitting diode 42a is mounted on only one surface of a substrate 42 housed in an outer peripheral portion 40e of the frame 40. The light-emitting diodes 42a are mounted on both sides of the substrate 42 accommodated in the partition 40f.

  As shown in FIG. 4, a rectangular opening 40g whose longitudinal direction is the X-axis direction is formed in the outer peripheral portion 40e and the partition wall portion 40f of the frame 40. As shown in FIG. 5, the light emitting diode 42a of the substrate 42 housed inside the outer peripheral portion 40e and the partition 40f is exposed from the opening 40g of the outer peripheral portion 40e and the partition 40f.

  FIG. 7 is a developed perspective view of the deodorizing mechanism 50. As shown in FIG. 7, the deodorizing mechanism 50 has a pair of connecting mechanisms 60 and three deodorizing panels 70.

  Each of the pair of connection mechanisms 60 includes a rectangular plate-shaped support member 61 whose longitudinal direction is the Z-axis direction, and a clamper 62. The support member 61 is a member made of a resin such as plastic, for example. On one surface of the support member 61, a convex portion 61a projecting in the X-axis direction is formed, and on the other surface, three grooves 61b having a longitudinal direction in the Y-axis direction are formed. The grooves 61b are arranged at equal intervals in the Z-axis direction, and are formed from the outer edge on the + Y side of the support member 61 to the vicinity of the outer edge on the -Y side.

  The clamper 62 has an arm 63 and a gripping member 64 that rotates about an axis S1 parallel to the X axis with respect to the arm 63.

  The arm 63 is made of a resin such as plastic, and is a rectangular parallelepiped member whose longitudinal direction is the Y-axis direction. On the upper surface of the arm 63, a pair of hinge portions 63a protruding toward the holding member 64 is provided. The −Y side end of the arm 63 is fixed to a protrusion 61 a formed on the support member 61.

  The gripping member 64 is made of a resin such as plastic similarly to the arm 63, and is a member slightly shorter in length than the arm 63. At the center of the holding member 64, a hinge portion 64a protruding toward the arm 63 is provided. The hinge portion 64a of the gripping member 64 is attached to the hinge portion 63a so as to be rotatable about the axis S1 with the hinge portion 64a being disposed between the pair of hinge portions 63a of the arm 63. The gripping member 64 is urged by a spring (not shown) so that the + Y side end of the gripping member 64 contacts the + Y side end of the arm 63. For this reason, the protrusion 21 b provided on the blower unit 20 can be held between the gripping member 64 of the clamper 62 and the end of the arm 63.

  The clamper 62 can be operated by, for example, pressing the −Y side end of the gripping member 64 against the arm 63 so as to approach the arm 63 to open the clamper 62, and releasing the pressed gripping member 64 to close the clamper 62.

  FIG. 8 is a developed perspective view of the deodorizing panel 70. The deodorizing panel 70 is a member whose longitudinal direction is the X-axis direction. The deodorizing panel 70 includes a deodorizing sheet 72 and a pair of frames 71 that support the deodorizing sheet 72 from both sides.

  The deodorizing sheet 72 is a rectangular sheet made of woven glass fiber, for example, and having a longitudinal direction as the X-axis direction. Titanium oxide as a photocatalyst is added to the glass fiber. As the photocatalyst, in addition to titanium oxide, for example, metal oxides such as tin oxide, zinc oxide, tungsten trioxide, strontium titanate, iron oxide, and bismuth oxide can be used.

  The frame 71 is a rectangular member slightly larger in size than the deodorizing sheet 72. The frame 71 has a thickness of about 0.5 mm and is made of, for example, a resin such as plastic. The frame 71 has three rectangular openings arranged in the X-axis direction. In the frame 71, most of the region is an opening.

  The above-described deodorizing sheet 72 and a pair of frames 71 are integrated by fixing the frames 71 with the deodorizing sheet 72 sandwiched between the frames 71. In the deodorizing panel 70 including the deodorizing sheet 72 and the pair of frames 71, most of the deodorizing sheet 72 is exposed from the opening of the frame 71.

  As can be seen from FIG. 7, the pair of connection mechanisms 60 and the three deodorizing panels 70 configured as described above are arranged such that both ends in the X-axis direction of the deodorizing panel 70 are provided on the support member 61 of the connection mechanism 60. By fitting into the groove 61b. The end of the deodorizing panel 70 fitted to the support member 61 is adhered to the support member 61 by, for example, an adhesive. Thereby, the pair of connection mechanisms 60 and the three deodorizing panels 70 are integrated, and the deodorizing mechanism 50 shown in FIG. 4 is assembled. The deodorizing mechanism 50 is detachably mounted on the frame 40.

  Specifically, as can be seen with reference to FIG. 4, the deodorizing mechanism 50 is mounted on the frame 40 by inserting the support member 61 of the connection mechanism 60 into the recess 40 b of the frame 40 from the −Y side of the frame 40. can do. When the support member 61 is inserted into the concave portion 40b of the frame 40, the convex portion 61a of the support member 61 fits into the notch 42c of the frame 40, and each of the deodorizing panels 70 is inserted into the slit 40d. Thereby, the deodorizing mechanism 50 is mounted on the frame 40 as shown in FIG. The deodorizing mechanism 50 attached to the frame 40 can be removed from the frame 40 by pulling out in the −Y axis direction.

  FIG. 9 is a diagram showing an AA cross section of the deodorizing unit 30 in FIG. When the deodorizing mechanism 50 is mounted on the frame 40, the deodorizing panel 70 is stored in the opening 40a of the frame 40. In this state, the deodorizing panel 70 faces the light emitting diodes 42a mounted on the board 42. Therefore, when power is supplied from the outside to the light emitting diode 42a mounted on the substrate 42, the light emitting diode 42a emits light and the deodorizing panel 70 is illuminated by the light emitting diode 42a.

  As shown in FIG. 1, the deodorizing unit 30 configured as described above is mounted on the blowing unit 20 by sandwiching the protrusion 21 b provided on the blowing unit 20 with the clamper 62 of the deodorizing unit 30. be able to. Further, by opening the clamper 62 of the deodorizing unit 30, the deodorizing unit 30 can be removed from the blower unit 20.

  Next, the operation of the deodorizing device 10 configured as described above will be described. In the deodorizing device 10, when power is supplied to the blowing unit 20 and the deodorizing unit 30, the blowing unit 20 is activated and air is supplied from the blowing unit 20 to the deodorizing unit 30. The air supplied to the deodorizing unit 30 is discharged to the outside through the opening 40a of the deodorizing unit 30. Light is emitted from the light emitting diodes 42 a of the deodorizing unit 30 toward the deodorizing panel 70.

  Substances harmful to the human body and substances that cause odor contained in the air flowing through the opening 40a of the deodorizing unit 30 are in contact with the deodorizing sheet 72 while the air flows along the deodorizing sheet 72 constituting the deodorizing panel 70. Decomposed by the photochemical reaction between them. In addition, pathogenic bacteria and viruses contained in the air are also inactivated by active oxygen generated by the photochemical reaction. Thus, deodorization and sterilization of air are performed.

  When the deodorizing device 10 operates for a long time, foreign substances such as dust adhere to the surface of the deodorizing sheet 72 constituting the deodorizing panel 70. If foreign matter adheres to the surface of the deodorizing sheet 72, sufficient contact between the deodorizing sheet 72 and air is impeded, and the deodorizing effect of the deodorizing sheet 72 is reduced. In such a case, the deodorizing mechanism 50 having the deodorizing panel 70 is removed from the frame 40 constituting the deodorizing unit 30, and the deodorizing mechanism 50 is washed with running water or the like. As a result, foreign substances and the like are removed from the surface of the deodorizing sheet 72, and the deodorizing effect of the deodorizing sheet 72 is restored.

  As described above, in the deodorizing apparatus 10 according to the present embodiment, the light emitting diode 42a is mounted, and the frame 40 that accommodates components that are vulnerable to moisture, such as the substrate 42, on the surface of which the electric circuit is formed; It is possible to easily separate the deodorizing mechanism 50 composed of parts that are not affected by moisture, such as the sheet 72. Therefore, only parts that are not affected by moisture can be easily washed using running water such as tap water.

  Further, in the deodorizing device 10 according to the present embodiment, the blowing unit 20 and the deodorizing unit 30 can be separated. Therefore, the operation for removing the deodorizing mechanism 50 from the frame 40 constituting the deodorizing unit 30 can be easily performed.

In this case, the protrusion 21b may be provided near the suction port of the blower unit 20.

  In the above embodiment, the deodorizing device 10 is driven by power supplied from, for example, an external power supply. However, the present invention is not limited thereto, and the deodorizing device 10 may be driven by a battery. Further, the battery and the AC power supply may be used together to drive the deodorizing device 10. In this case, the battery is preferably a rechargeable secondary battery.

  In the above embodiment, the deodorizing unit 30 constituting the deodorizing device 10 is detachably attached to the blower unit 20 using the clamper 62. However, the invention is not limited thereto, and the deodorizing unit 30 may be attached to the blower unit 20 or the like using a mechanism instead of the clamper 62.
