Hereinafter, with reference to FIG. 1, the external appearance of the deodorizing apparatus 1 is mainly demonstrated. In this specification, unless otherwise specified, the front-rear direction is designated with the front side in FIG.

<Appearance of main body case>
As shown in FIG. 1, the deodorizing apparatus 1 includes a body case that forms an outer shell. The main body case has a box shape made of resin. Although not shown in detail, the main body case is composed of a plurality of parts such as a front panel part and a case part for storing various functional parts. Moreover, the main body case includes a control unit (not shown) that controls the operation of each unit of the deodorizing apparatus 1.

  An operation unit 26 is provided on the upper surface of the main body case. The operation unit 26 includes a plurality of operation buttons and LEDs that form a display unit. An operation board (not shown) on which operation buttons, LEDs, and the like included in the operation unit 26 are mounted is attached to the inside of the main body case. This operation board is electrically connected to the control unit described above.

  A detection means 92 is provided on the upper surface of the main body case. The detection means 92 detects the position of a person around the deodorizing apparatus 1. Furthermore, the detection means 92 transmits a signal to the control unit described above.

  The front side of the main body case is open, and a front panel that covers this is removably attached. An air inlet 11 is formed in the front panel. The air suction port 11 includes a plurality of slit-like through holes extending in the left-right direction. The air suction port 11 ensures air permeability through the front panel so that air can flow in the front-rear direction.

  The rear surface side of the main body case has a closed box shape. An opening serving as an air outlet 42 is formed on the upper surface of the main body case. Here, as the air outlet 42, a first outlet 421 and a second outlet 422 are formed.

  FIG. 2 is a YY sectional view of the deodorizing apparatus 1 shown in FIG. Hereinafter, mainly the internal structure of the deodorizing apparatus 1 will be described with reference to FIG.

<Ventilation path>
Blower means 44 is attached to the rear side of the inside of the main body case. The air blowing means 44 is a multi-blade fan (sirocco fan) to which a large number of wings having a certain width in the direction along the rotation axis are attached. That is, the blower unit 44 includes a large number of wings arranged at a certain radius from the rotation axis. A blower opening (not shown) surrounded by these wings opens forward, that is, toward the air inlet 11. In addition, a motor (not shown) that rotationally drives the air blowing means 44 is attached so that the rotation shaft is disposed forward and horizontally. The air blower 44 is rotationally driven to suck air from the air blower opening facing forward, and discharges air in the radial direction of the air blower 44 including the upper part.

  In addition, the ventilation means opening part mentioned above is located in the approximate center of a main body case in the up-down direction. The air blowing means 44 is formed so that the projected area X of the main body case in the front view and the area Y of the air blowing means opening in the front view satisfy the relationship of Y ≧ 0.6X.

  Inside the main body case, a ventilation path R extending from the air suction port 11 to the air blowout port 42 through the air blowing means 44 is formed. The ventilation path R branches to a ventilation path RA that reaches the first air outlet 421 and a ventilation path RB that reaches the second air outlet 422 on the downstream side of the air blowing means 44. The ventilation path RA is formed so as to extend linearly from the blower means 44 toward the first air outlet 421. On the other hand, the ventilation path RB is formed as a space from the opening provided in the inner wall that forms the ventilation path RA to the second air outlet 422. The ventilation path RA and the ventilation path RB are formed such that the width D of the ventilation path RA is larger than the width D ′ of the ventilation path RB.

  A louver 46 that changes the direction of the air discharged from the air outlet 42 or closes the air outlet 42 is provided in the vicinity of the air outlet 42 inside the main body case. Here, as the louver 46, a first louver 461 and a second louver 462 are provided. The first louver 461 and the second louver 462 include a plurality of plate-like wind direction plates (not shown). The first louver 461 and the second louver 462 include a link mechanism (not shown) that connects a plurality of wind direction plates and adjusts the angle of the wind direction plates. Furthermore, the louver 46 includes a drive unit (not shown) such as a motor that moves the link mechanism.

  The plurality of plate-like wind direction plates provided in the louver 46 face the opening of the air outlet 42 and are arranged side by side so as to be parallel to each other with a certain interval. Each wind direction plate is supported by the air outlet 42 by shafts (not shown) formed at both ends. The direction and the open / close state of the louver 46 are changed by the control unit controlling the operation of the drive unit according to the state of the deodorizing apparatus 1. A lattice is provided at the opening of the air outlet 42 so that the louver 46 cannot be directly touched from the outside.

  Further, a flow dividing member 91 is provided on the outer upper surface of the main body case. The flow dividing member 91 is a guide for preventing the air discharged from the first air outlet 421 and the air discharged from the second air outlet 422 from mixing. The flow dividing member 91 is supported by the second air outlet 422 by a shaft (not shown). This shaft is formed at one end of the second air outlet 422 adjacent to the first air outlet 421. The direction and the open / closed state of the flow dividing member 91 are changed by the control unit controlling the operation of the drive unit according to the state of the deodorizing apparatus 1.

<Deodorizing means>
Deodorizing means is accommodated in the main body case upstream of the air blowing means 44. The deodorizing means includes a pre-filter 13 and a HEPA (High Efficiency Particulate Air) filter 12 disposed on the downstream side thereof. The HEPA filter 12 is formed in the same size as the range where the air inlet 11 of the front panel is formed. The HEPA filter 12 is a filter for removing fine dust such as pollen, mite feces, mold spores, house dust and the like contained in the air. The pre-filter 13 is a coarse filter for removing large dust contained in the air before filtering the air with the HEPA filter 12. This is used for the purpose of maintaining the effect of the HEPA filter 12 for a long period of time.

  Further, the deodorizing means includes a deodorizing element 62 disposed on the downstream side of the HEPA filter 12. The deodorizing element 62 is formed in a disk shape that has a circular shape when viewed from the front. Further, the deodorizing element 62 is rotatably held on a shaft (not shown) provided on the partition plate 65. The deodorizing element 62 is obtained by applying or impregnating a catalyst with a binder to a honeycomb core having a plurality of openings formed in a honeycomb shape using ceramic or aluminum as a raw material. As this catalyst, for example, a catalyst having a property of adsorbing an odorous substance (particularly ammonia odor) such as a catalyst using platinum and manganese, or a catalyst having a property of oxidizing and decomposing the odorous substance by heating is used. The deodorizing element 62 formed in this way is a part that removes odor from the air by allowing the room air taken into the deodorizing apparatus 1 to pass therethrough.

<Heating means>
Further, the deodorizing means includes a heating means 63 disposed on the downstream side of the deodorizing element 62. The heating means 63 is disposed below the center of the deodorizing element 62 so as not to prevent the rotation of the deodorizing element 62. The heating means 63 includes a heater unit that locally heats the deodorizing element 62 and a case having an internal space in which the heater unit is housed. In this case, the side facing the deodorizing element 62 is opened. The heater unit is directly opposed in the vicinity of the deodorizing element 62. The heater unit is electrically connected to the control unit of the deodorizing apparatus 1 and is energized and controlled according to the state of the deodorizing apparatus 1.

  The heater unit includes a plate-like heat generating portion and a heater portion that heats the heat generating portion. The heat generating part has a fan shape in a front view. Further, a black heat-resistant coating for improving the emissivity of heat received from the heater portion is applied to the surface of the heat generating portion. That is, the heater unit receives the heat generated in the heater part by the plate-like heat generating part and radiates heat from the entire plate surface, thereby heating the opposing deodorizing element 62 with little unevenness. In addition, when the heater unit is energized for a preset time, the heater unit has a heating capability that can raise the temperature of the portion facing the deodorizing element 62 to a temperature at which the odorous substance adsorbed on the deodorizing element 62 can be oxidatively decomposed. It is set.

  Note that a PTC (Positive Temperature Coefficient) heater, which is a semiconductor ceramic mainly composed of barium titanate, is used for the heater portion in the heater unit. PTC heaters have self-temperature controllability and do not require external temperature control. For this reason, since intermittent control is not performed like a thermostat, there exists an advantage that it can be used stably, without generating a spark and noise.

  Further, the deodorizing means includes a partition plate 65 disposed on the downstream side of the HEPA filter 12 and on the upstream side of the deodorizing element 62. The middle partition plate 65 is formed with a circular opening that extends in the front-rear direction, and other than the opening is closed. The opening is provided with a radial frame to prevent the user from directly touching the deodorizing element 62 and a lid 65d described later.

  In addition, the deodorizing means includes a fan-shaped lid 65d. A fan-shaped region having a preset center angle that extends equally to the left and right, which is a region below the opening of the middle partition plate 65, is covered with a lid 65d. The lid body 65d is made of, for example, stainless steel. The lid body 65d is attached by fixing with screws or the like from the rear surface side (back surface side) of the middle partition plate 65.

  The lid 65d is disposed so as to face the heating means 63 with the deodorizing element 62 interposed therebetween. Furthermore, the lid 65d has a size capable of covering the heating means 63. That is, the heating space for heating the deodorizing element 62 is formed by the heating means 63 and the lid body 65d facing each other. The lid 65d is provided with a black heat-resistant coating for improving the thermal emissivity. Moreover, the area | region which heats the deodorizing element 62 is covered with the heat retention material so that heat may not escape. Thereby, the heating means 63 can heat the site | part which the deodorizing element 62 opposes locally efficiently.

  The deodorizing means includes a driving means 64. The driving means 64 includes a motor and a bracket that holds the motor. A gear is attached to the rotating shaft of the motor. The motor is electrically connected to the control unit of the deodorizing apparatus 1 and is energized and controlled according to the state of the deodorizing apparatus 1.

  In the driving means 64, the bracket is fixed to the partition plate 65 in a state where the motor is held by the bracket. At this time, the gear attached to the rotating shaft of the motor meshes with a gear (not shown) provided on the deodorizing element 62.

  By providing the driving means 64 as described above, the deodorizing element 62 can be rotated by driving the motor by energization control by the control unit. For this reason, the site | part facing the heating means 63 of the deodorizing element 62 can be changed. That is, the drive unit 64 has a function as a position changing unit that changes the relative positional relationship between the heating unit 63 and the deodorizing element 62.

  Further, the position where the driving means 64 is disposed is a rear surface of the middle partition plate 65 and is a region sandwiched between the opening and the corner portion of the middle partition plate 65. The position where the driving means 64 is disposed is preferably an upper position away from the heating means 63. This is because the driving unit 64 is less susceptible to the heat generated from the heating unit 63.

  Next, operation | movement of the deodorizing apparatus 1 comprised as mentioned above is demonstrated. As described above, a ventilation path R extending from the air inlet 11 to the air outlet 42 is formed in the deodorizing apparatus 1. Hereinafter, description will be made along the air flow in the ventilation path R.

<Deodorizing operation>
When the user operates the operation unit 26, the control unit executes a control program for controlling the operation of the deodorizing apparatus 1. When the operation is started, the air blowing means 44 is driven to generate a suction force for taking in the room air from the air suction port 11 into the deodorizing apparatus 1, and the room air flows into the air suction port 11. The air taken in from the air suction port 11 flows rearward, and after removing large dust with the pre-filter 13, fine dust is removed with the HEPA filter 12.

  The air from which the dust has been removed flows further rearward and reaches the deodorizing element 62. When air passes through the honeycomb-shaped opening, odorous substances contained in the air are adsorbed by the catalyst applied to the deodorizing element 62. As a result, odorous substances are removed from the air passing through the deodorizing element 62. The “state in which odor is removed from the air” includes not only a state in which the odor is completely removed from the air, but also a state in which the odorous substance is reduced as compared with the state before passing through the deodorizing element 62.

  When the deodorizing apparatus 1 is continuously operated, the adsorbed odorous substance is accumulated in the deodorizing element 62. And the deodorizing performance of the deodorizing element 62 falls as the adsorbed odor increases.

  The air from which dust and odorous substances have been removed flows further backward from the deodorizing element 62 and reaches the blowing means 44. The air that has reached the air blowing means 44 is sucked from the air blowing means opening in the axial direction of the air blowing means 44 and is discharged in the radial direction of the air blowing means 44 including the upper part.

  The air discharged from the blower 44 flows into the ventilation path RA or the ventilation path RB. The air flowing through the ventilation path RA is adjusted in air direction when passing through the first louver 461, and is discharged as clean air from the first air outlet 421 to the outside of the deodorizing apparatus 1. When the air flowing through the ventilation path RB passes through the second louver 462, the air direction is adjusted, and the air is discharged from the second outlet 421 to the outside of the deodorizing apparatus 1 as clean air.

  The detecting means 92 (see FIG. 1) automatically detects the position of the user. Further, the detection unit 92 transmits a signal including the position information of the user to the control unit. The control unit controls the louver 46 and the flow dividing member 91 based on the signal received from the detection unit 92 and adjusts the wind direction. At this time, the second louver 462 is controlled such that air is discharged from the second air outlet 422 toward the upper body of the user. In addition, air from the second outlet 422 is directed to the upper body of the user who is not the source of odor in order to prevent the odor from diffusing into the room.

  On the other hand, the first louver 461 is controlled so that air is discharged from the first air outlet 421 toward a place where there is no user. The air discharged from the first air outlet 421 is for circulating indoor air.

  As shown in FIG. 2, the path from the air blowing means 44 to the first air outlet 421 through the ventilation path RA is linear. On the other hand, the path from the blowing means 44 to the second outlet 422 via the ventilation path RB is bent. For this reason, the pressure loss in the route passing through the ventilation path RB is larger than that in the route passing through the ventilation path RA. Thereby, the air speed | velocity | rate released toward a user from the 2nd blower outlet 422 becomes small compared with the air discharge | released from the 1st blower outlet 421. FIG. This wind speed is so small that a person who is being blown by the wind does not feel discomfort such as strong wind, cold, or dryness.

  Further, as described above, the width D ′ of the ventilation path RB is formed smaller than the width D of the ventilation path RA. For this reason, the air discharged toward the user from the second air outlet 422 has a smaller air volume than the air discharged from the first air outlet 421.

  In this way, the ventilation path R is an air path that is connected horizontally from the air suction port 11 to the rear part of the deodorizing device 1 and changes the direction upward at this rear part to reach the air outlet 42. In the ventilation path R, dust filtering filters such as the prefilter 13 and the HEPA filter 12 are disposed on the upstream side of the deodorizing element 62 when the air flow is taken as a reference. A bent portion is formed on the downstream side of the deodorizing element 62, which is a position where the direction of air flow is bent upward and changed. The sirocco fan which is the ventilation means 44 is located in this bending part. The sirocco fan takes in air from the direction of the rotation axis and exhales the air taken in the radial direction. For this reason, the sirocco fan can create a straight air flow from the front to the rear of the main body case, and can efficiently change the direction of the wind toward the air outlet 42.

  Further, the pre-filter 13, the HEPA filter 12, the deodorizing element 62, and the air blowing means opening are arranged in a direction perpendicular to the direction of the air flowing through the ventilation path R. Thus, air is applied perpendicularly to each filter surface and the deodorizing element 62, and dust filtration and deodorization are efficiently performed.

<Playback operation>
Next, an operation (hereinafter also referred to as a regenerating operation) for recovering the deodorizing performance of the deodorizing element 62 that has adsorbed many odorous substances and reduced the deodorizing performance by operating the deodorizing apparatus 1 will be described.

  The control unit of the deodorizing apparatus 1 performs a reproduction operation at a preset timing. For example, when the cumulative operation time from the regeneration operation of the deodorizing element 62 that was started or last performed exceeds a preset time, the control unit performs the regeneration operation as follows. The reproduction operation is preferably performed once or more in 24 hours.

  In a state where the air blowing means 44 is stopped, that is, after the deodorizing apparatus 1 finishes the deodorizing operation or in a state where the deodorizing operation is not performed, the control unit heats the heater unit by energizing. A heater unit heats the site | part of the deodorizing element 62 which opposes, and raises it to the preset temperature. This heating is continued for a preset time.

  The heating temperature and heating time of the deodorizing element 62 at this time are sufficient temperature and time for removing the odorous substance adsorbed on the deodorizing element 62. In addition, since the heating means 63 and the deodorizing element 62 are opposed to each other through air, there is a difference between the temperature of the heating means 63 and the temperature of the deodorizing element 62. This is because the air is cooled by the air layer, and the control unit controls the temperature of the heater unit in consideration of the temperature difference.

  The length of the heating time α ′ when the temperature is raised to a preset temperature α in order to recover the deodorizing performance of the deodorizing element 62 is determined in view of the design reason of the deodorizing device 1. This design reason is, for example, the temperature of the use environment, the type of odor to be deodorized, whether or not the catalyst is attached to the deodorizing element 62, the type of catalyst, and the like. Here, the start time of the heating time α ′ is set at the start of the regeneration operation or when the temperature α is reached, and the end time of the heating time α ′ is set at the end of the regeneration operation.

  The blowing means 44 during the regenerating operation may be in a stopped state or an operating state. In order to efficiently heat the deodorizing element 62, it is preferable to stop the blowing means 44. On the other hand, it is preferable to operate the air blowing means 44 because the product generated by the oxidative decomposition of the odorous substance in the regenerating operation can be removed from the vicinity of the deodorizing element 62 and the oxidative decomposition reaction can be promoted. Therefore, it is desirable to optimize the state of the blowing means 44 during the regenerating operation, including the combined use of the stopped state and the operating state, depending on the characteristics of the odorous substance and the usage environment.

  In addition, as for the site | part to which the deodorizing element 62 is heated, the front side is covered with the cover body 65d to which the coating which improves the emissivity of heat is given, and the rear side is covered with the heater unit of the heating means 63. For this reason, the deodorizing element 62 can be efficiently heated by the heat generated from the heater unit and the heat radiated from the lid 65d. Further, the deodorizing element 62 is located in a heating space sandwiched between the heater unit and the lid body 65d. Since heat tends to stay in this heating space, the deodorizing element 62 can be heated more efficiently.

  Next, when the regeneration operation of the portion facing the heating unit 63 is completed, the control unit operates the drive unit 64 to rotate the deodorizing element 62 by a preset angle. By this operation, the part where the heat treatment of the deodorizing element 62 facing the heating means 63 is shifted in the rotation direction with respect to the heating means 63. As a result, the part of the deodorizing element 62 that has been subjected to the heat treatment is removed from the position sandwiched between the heating means 63 and the lid 65d, and the part of the deodorizing element 62 that has newly adsorbed a large amount of odorous substance is replaced with the heating means. It will be located in the heating space between 63 and the lid 65d.

  In addition, the angle which rotates the deodorizing element 62 is the same as the center angle of the fan-shaped heating means 63, or an angle smaller than this center angle is good. By setting the rotation angle in this way, any part of the deodorizing element 62 always remains in front of the heating means 63 and is subjected to heat treatment while the deodorizing element 62 rotates once. The timing for moving the deodorizing element 62 may be immediately after the heat treatment or immediately before the next deodorizing operation.

<Effect>
By configuring each part of the deodorizing apparatus 1 as described above, the following effects can be obtained.

  As described above, the deodorizing apparatus 1 in the present embodiment conveys part of the air cleaned by the deodorizing element 62 toward the user. Thereby, since the path | route from an odor generation source to a user's nose is interrupted | blocked, a user can be made to feel a deodorizing effect in a shorter time. This is because, for example, there is a clear odor generation source such as diaper exchange, and the odor contains a lot of odor components with a low sensory threshold, so even the high-performance deodorizing element 62 has an odor below the sensory threshold. This is effective in situations where there is a time lag before removal. In particular, the deodorizing effect can be realized without odor diffusion by conveying the air to a place where no odor generating source exists, such as the user's upper body.

  Further, as described above, in the present embodiment, by providing the flow dividing member 91, air having a high wind speed from the first air outlet 421 and air having a low air speed from the second air outlet 422 are mixed. That is restrained. For this reason, the wind direction is not disturbed and the odor near the odor source is not diffused into the room. Moreover, the air from the 1st blower outlet 421 is discharge | released toward the place where a user does not exist. For this reason, even if air with a large air volume and high wind speed is discharged from the first air outlet 421 due to the large air volume, the odor near the odor generating source is not diffused indoors. Furthermore, since the odor near the odor generating source can be treated with a large air volume, the deodorizing effect can be obtained in a shorter time.

  Further, as described above, in the present embodiment, the path from the air blowing means 44 to the second air outlet 422 via the ventilation path RB is bent. For this reason, the pressure loss is large in the route passing through the ventilation path RB, and the air speed of the air discharged from the second air outlet 422 toward the user is low. As a result, discomfort given to the user such as strong wind, cold, and drying can be reduced.

  As described above, in the present embodiment, when the heater unit of the heating unit 63 is energized for a preset time, the temperature of the deodorizing element 62 can be increased to a temperature at which the odorous substance can be oxidatively decomposed. The heating capacity is set. For this reason, it is possible to decompose the odor substance adsorbed on the deodorizing element 62 and to recover the deodorizing performance.

  Moreover, as above-mentioned, in this Embodiment, the relative positional relationship of the deodorizing element 62 and the heating means 63 can be changed. For this reason, when heat-treating the entire area of the deodorizing element 62, it is not necessary to arrange a large heater that faces the entire area of the deodorizing element 62. As a result, the heating means 63 can be reduced in size, and the structure can be simplified and the cost can be reduced.

  Further, since it is not necessary for the heating means 63 to cover the entire area of the deodorizing element 62, it is sufficient that the deodorizing element 62 faces the heating means 63 in a limited portion. For this reason, the flow of air hindered by the heating means 63 can be minimized. As a result, more air can be flowed to the deodorizing element 62, and more odorous substances can be removed from the air at once. In particular, in the present embodiment, since the heating means 63 is formed in a fan shape, the area covering the deodorizing element 62 can be minimized. In addition, the magnitude | size of the fan-shaped center angle is set with the one rotation angle at the time of rotating the deodorizing element 62 as a standard.

  Furthermore, since the relative positional relationship between the deodorizing element 62 and the heating means 63 can be changed, any part of the deodorizing element 62 can be heated with the heating means 63 facing each other. For this reason, the deodorizing element 62 can be heated with little unevenness and the deodorizing performance can be efficiently recovered.

  Moreover, as above-mentioned, the air suction inlet 11 is formed in the front panel. For this reason, the front surface of the main body case with a large opening is opposed to the odor generating source, and the indoor air can be sucked and deodorized more quickly. Moreover, the air outlet 42 is formed in the upper surface of a main body case. For this reason, it is difficult for clean air to flow to the odor generating source, and odor diffusion can be prevented.

  Further, as described above, the deodorizing element 62 has a disk shape. For this reason, when viewed from the rotational axis direction of the deodorizing element 62, the area of the deodorizing element 62 itself and the area of the rotation region necessary for the deodorizing element 62 to rotate are substantially the same. That is, the area of the rotation region relative to the area of the deodorizing element 62 itself can be minimized. Therefore, the arrangement | positioning area | region of the deodorizing element 62 in a main body case can be made small.

  Further, the deodorizing element 62 has a disk shape and rotates to change a portion facing the heating means 63. For this reason, the heater unit of the heating means 63 can heat many areas of the deodorizing element 62 even if the radial size of the deodorizing element 62 is the same as or smaller than the rotation radius of the deodorizing element 62. is there.

  Furthermore, since the deodorizing element 62 has a disk shape, it is possible to form an area that is as wide as possible with respect to the projected area of the main body case that has a rectangular shape in front view while realizing the above-described effects. is there. For this reason, the area | region which can deodorize can be formed more largely. Thereby, since more air can flow through the deodorizing element 62, the amount of air taken into the deodorizing apparatus 1 can be increased while maintaining the deodorizing performance.

  As described above, the deodorizing element 62 is obtained by applying or impregnating a catalyst having ammonia adsorption and oxidative decomposition functions on the surface. Thereby, while deodorizing pet odor or the care odor in a hospital, a care facility, a care field etc. quickly, the deodorizing apparatus 1 which can oxidize and decompose an odor substance efficiently by heating is realizable. In particular, in this embodiment, odor can be removed from more air in a short period of time, so it is possible to quickly deal with odor problems in places used by many people such as hospitals and care facilities. It is possible to solve.

  Further, as described above, in the ventilation path R, the deodorizing element 62 is located on the upstream side of the blowing means 44. A heating means 63 is disposed between the deodorizing element 62 and the air blowing means 44. For this reason, the space provided in order to reduce the pressure loss which arises around the deodorizing element 62 and the ventilation means opening part can be used in order to arrange | position the heating means 63. FIG. Further, since clean air flows into the air blowing means 44, odorous substances do not adhere to the air blowing means 44 and odor is not released from the air outlet 42.

  Further, as described above, the control unit executes a control program for controlling the operation of the deodorizing apparatus 1. In accordance with this control program, the driving means 64 that is the position changing means is driven at a preset timing to rotate the deodorizing element 62. Thereby, when the deodorizing element 62 is heated, the part of the deodorizing element 62 to be deodorized can be automatically opposed to the heating means 63. Further, the control program includes a processing step in which the drive unit 64 is rotated by a preset angle and then stopped, and the heating unit 63 is energized for a preset time in the stopped state. Thereby, a series of operation | movement from rotation of the deodorizing element 62 to heating can be performed automatically by a control part.

  As described above, the prefilter 13 and the HEPA filter 12 that are dust filtration filters are installed on the upstream side of the deodorizing element 62, and a front panel is detachably attached to the front surface of the main body case. For this reason, it is possible to take out the dust filtration filter forward of the main body case with the front panel removed from the main body case. Thereby, the maintainability of the dust filtration filter which a large dust tends to adhere can be improved.

  Further, as described above, the heating means 63 is disposed below the rotation center of the deodorizing element 62. Thus, the center of gravity of the deodorizing apparatus 1 can be lowered by disposing the heating unit having a certain amount of weight because it has a heater unit or the like at a low position. Thereby, the deodorizing apparatus 1 which can be installed stably on a floor surface can be comprised.

  Moreover, as above-mentioned, the ventilation means opening part is located in the approximate center of the main body case in the up-down direction. Further, the air blowing means 44 is formed so that the projected area X of the main body case in the front view and the area Y of the air blowing means opening in the front view satisfy the relationship of Y ≧ 0.6X. Thereby, the relationship in which the ventilation means 44 can take in air to the maximum with respect to the projection area of the main body case in the front view is established. As a result, it is possible to realize the deodorizing apparatus 1 that can take in more room air and flow it to the deodorizing element 62.

The base material carrying the fragrance is formed of a material such as zeolite, paper, resin, ceramic, a granular member composed of an organic compound, a piece of wood, etc., and has a breathable structure. When zeolite is used as the substrate, the amount of the fragrance component released varies depending on the humidity and temperature of the aerated air, utilizing the molecular sieve or chemical function of the zeolite. For this reason, by selecting a fragrance that is compatible with the characteristics of the individual base material, the amount of the fragrance component is increased when the humidity is high, or the fragrance component released indoors is adsorbed by the deodorizing element 62. It is possible to adopt a configuration that is not performed.

  Moreover, the odor removal component discharge | release means 93 may be provided with the device which produces | generates ozone, activated species, etc. electrically. In this case, the generating device electrically connected to the control unit of the deodorizing apparatus 1 operates to generate ozone, active species, and the like.

  Next, the operation in the second embodiment will be described. In the present embodiment, when the operation of the deodorizing apparatus 1 is started, the air that has reached the ventilation path RA through the deodorizing element 62 and the air blowing means 44 is discharged from the first air outlet 421 as in the first embodiment. . On the other hand, the air that has flowed into the ventilation path RB passes through the odor removing component discharge means 93 disposed in the vicinity of the second air outlet 422, the air direction is adjusted by the second louver 462, and the second air outlet 422. Released from.

  When the odor removing component releasing means 93 includes a base material carrying a fragrance, the air is passed through the odor removing component releasing means 93 so that the fragrance component is detached from the base material and mixed with the air. In this case, it is preferable that the air from the 2nd blower outlet 422 is discharge | released toward a user.

  When the odor removing component releasing means 93 includes a device that electrically generates ozone, active species, and the like, the generated ozone and active species are mixed with the air that has passed through the odor removing component releasing means 93. In this case, it is also preferable to transport the air discharged from the second outlet 422 to the odor generating source instead of the user. Also, the indoor space can be deodorized by releasing air toward the indoor walls, curtains, and the like.

  As described above, in this embodiment, the odor removing component releasing means 93 is provided in the ventilation path RB. When the odor removing component releasing means 93 includes a base material carrying a fragrance, the odor is masked by the fragrance component by releasing air toward the user. For this reason, the user can feel the deodorizing effect in a short time. Further, the odor removing component releasing means 93 can be configured to increase the amount of the fragrance component released when the humidity is high. This makes it possible to sufficiently mask the odor even in a high humidity state, which is generally said to increase the human odor sensory ability, such as in rainy weather. For this reason, the user can feel the deodorizing effect in a short time without being affected by the humidity state of the surrounding environment.

  In addition, when the odor removing component releasing means 93 includes a device that electrically generates ozone, active species, and the like, the odor substance can be decomposed and removed by conveying the air to the odor generating source. it can.
