Description

  The present invention relates to a deodorizing apparatus.

  Patent Document 1 listed below describes a deodorizing apparatus that adsorbs an odor component (odor substance) by a deodorizing means and performs deodorization. In the deodorizing apparatus described in Patent Document 1, the deodorizing performance of the deodorizing means is recovered by simultaneously heating the entire deodorizing means.

By attaching a predetermined catalyst to the deodorizing means, the deodorizing performance of the deodorizing means can be recovered. That is, when the deodorizing means is heated, the odorous substance is oxidatively decomposed by the catalyst.
Even if an oxidative decomposition catalyst is attached to the deodorizing means, a part of the odorous substance is detached from the deodorizing means while the deodorizing means is heated to a temperature effective for oxidative decomposition. For this reason, the odorous substance is re-released in the room, and for example, an unpleasant odor may be generated from the deodorizing apparatus immediately after the deodorizing apparatus is operated.

  Patent Document 2 listed below describes a deodorizing apparatus including a decomposition unit on the downstream side of an adsorption unit.

Embodiment 1 FIG.
1 is a perspective view showing an appearance of a deodorizing apparatus according to Embodiment 1 of the present invention. FIG. 2 is a perspective view showing the inside of the deodorizing apparatus according to Embodiment 1 of the present invention. FIG. 3 is a longitudinal sectional view showing the deodorizing apparatus according to Embodiment 1 of the present invention.

  1 to 3, reference numeral 1 denotes a main body case (main body) of the deodorizing apparatus. The main body case 1 has a rectangular parallelepiped box shape. The body case 1 is made of resin or the like. The main body case 1 includes a front cover 2 and a back cover 3. FIG. 2 shows a state where the front cover 2 is removed from the main body case 1.

The main body case 1 is formed with a suction port 4, an air outlet 5, and a ventilation path 6.
The suction port 4 is for taking outside air into the body case 1. The suction port 4 includes an opening formed on the side surface of the main body case 1. The main body case 1 communicates with (in communication with) the outside through the suction port 4. For example, the suction port 4 is provided in the lower part of the front cover 2 and the lower part of the back cover 3. In the present embodiment, as the suction port 4, a plurality of openings are arranged vertically at the lower part of the front cover 2 and the lower part of the rear cover 3, and the shape thereof is a rectangle having a length in the width direction of the main body case 1. It is in the shape. The suction port 4 shown in the figure is an example, and the arrangement, shape, and number of the suction ports 4 are appropriately set depending on the design reason of the deodorization apparatus.

  The blower outlet 5 is for discharging the air inside the main body case 1 to the outside. The air outlet 5 includes an opening formed in the main body case 1. The main body case 1 communicates with (in communication with) the outside through the air outlet 5. For example, the air outlet 5 is provided on the upper surface of the main body case 1. Also about the blower outlet 5, the arrangement | positioning, a shape, and a number are suitably set by the design reason of a deodorizing apparatus.

  The ventilation path 6 is an air passage formed inside the main body case 1. The ventilation path 6 connects the suction inlet 4 and the blower outlet 5 (connects without interrupting | blocking). In the present embodiment, the ventilation path 6 is formed in the entire interior of the main body case 1. Also about the ventilation path 6, the path | route and shape are suitably set by the design reason of a deodorizing apparatus.

  The body case 1 is provided with an air blowing means 7, a deodorizing means 8, a heating means 9, and a control means (not shown).

  The air blowing means 7 is for generating an air flow inside the main body case 1. The air blowing means 7 is provided in the ventilation path 6 and is disposed in the vicinity of the air outlet 5, for example. In the present embodiment, since the air outlet 5 is formed on the upper surface of the main body case 1, the air blowing means 7 is arranged at the upper part of the main body case 1 (just below the air outlet 5). When the air blowing means 7 is driven, an air flow is generated inside the main body case 1. That is, air is taken into the inside of the main body case 1 (ventilation path 6) from the suction port 4. The air taken into the inside of the main body case 1 (the ventilation path 6) flows upward between the front cover 2 and the back cover 3 and passes through the ventilation path 6. The air that has passed through the ventilation path 6 is discharged from the air outlet 5.

  The blowing means 7 shown in the figure is an example. The air blowing means 7 may be arranged either horizontally or vertically with respect to the installation surface of the deodorizing device (main body case 1). The configuration and arrangement of the air blowing means 7 are appropriately set depending on the design reason of the deodorizing device.

  The deodorizing means 8 is for deodorizing by adsorbing odor components (odorous substances) in the air when the air passes through. The deodorizing means 8 is provided in the ventilation path 6. The deodorizing means 8 has, for example, a circular shape whose outer shape has a predetermined thickness. The deodorizing means 8 is formed so that air can pass through. For example, the deodorizing means 8 is formed of a honeycomb, fin, mesh, or plate material. A predetermined material that adsorbs odorous components such as activated carbon and zeolite is attached to the deodorizing means 8. The deodorizing means 8 is attached with a predetermined catalyst having an oxidative decomposition action of odor components by heating.

  The deodorizing means 8 is arranged over almost the entire area in the cross-sectional direction of the ventilation path 6 (substantially the entire direction orthogonal to the direction of air flow) so that as much air as possible passes through. In this Embodiment, the deodorizing means 8 is arrange | positioned in parallel with respect to the installation surface where the deodorizing apparatus (main body case 1) touches the ground between the front cover 2 and the back cover 3. That is, the deodorizing means 8 is horizontally disposed in a portion of the ventilation path 6 where air flows upward with respect to the installation surface of the deodorizing device (main body case 1). Here, the horizontal direction of the deodorizing means 8 means that the air passing through the ventilation path 6 can be arranged so as to pass through the deodorizing means 8. A plurality of deodorizing means 8 may be arranged in the air flow direction in accordance with the deodorizing performance required for the deodorizing apparatus and the size of the deodorizing apparatus.

The deodorizing means 8 is driven by a driving means (not shown) such as a motor. In the present embodiment, the deodorizing means 8 is rotated in one direction (or both directions) around the central axis (facing the vertical direction) by being driven by the driving means.
The distance between the deodorizing means 8 and the ventilation path 6 should just provide the minimum space for the deodorizing means 8 to drive, for example, the distance of the edge part of the deodorizing means 8 and the wall surface of the ventilation path 6 facing it. Is 1 cm or less. If the distance between the deodorizing means 8 and the ventilation path 6 is too large, the odor component does not pass through the deodorizing means 8 during the deodorizing operation, resulting in a decrease in the deodorizing effect.

  The heating means 9 is for heating the deodorizing means 8. The heating means 9 heats the deodorizing means 8 to restore the deodorizing performance of the deodorizing means 8. The heating means 9 is provided in the ventilation path 6. The heating means 9 is disposed on the downstream side of the deodorizing means 8. In the present embodiment, since the deodorizing means 8 is disposed in a portion where air flows upward, the heating means 9 is disposed above the deodorizing means 8.

The lower surface of the heating unit 9 faces a part of the upper surface of the deodorizing unit 8. For this reason, a minute heating space is formed between the deodorizing means 8 (the upper surface thereof) and the heating means 9 (the lower surface thereof). It is good also as a structure which surrounds this heating space with a heat insulating material etc. and improves heat retention. The heating means 9 is formed so that air can pass through. For example, the heating means 9 is formed of a honeycomb, fin, mesh, or plate material. The shape for allowing air to pass therethrough does not need to be matched between the deodorizing means 8 and the heating means 9.
In addition, it is preferable that the spatial distance between the deodorizing means 8 and the heating means 9 is 1 cm or less. This is because the deodorizing means 8 can be driven, and it is preferable that the space is a minimum space for transmitting the heat of the heating means 9 to the deodorizing means 8 with as little loss as possible.

  The heating means 9 includes, for example, a predetermined heating element and a base material to which a predetermined oxidative decomposition catalyst is attached. A heat generating body and a base material are provided integrally. The heating element includes an element that generates heat when energized. The oxidative decomposition catalyst provided on the base material is activated when it reaches a predetermined temperature, and oxidatively decomposes odorous components (odorous substances). The base material holding the oxidative decomposition catalyst is made of a material whose thermal conductivity is higher than that of the deodorizing means 8, for example. The thermal conductivity of the substrate is preferably 10 W / (m · k) or more. If the substrate is made of a predetermined metal, it is easy to obtain a desired thermal conductivity. However, it is not necessary to limit the material of the base material to metal.

  FIG. 4 is a diagram showing an arrangement relationship between the deodorizing means and the heating means. For example, the heating means 9 overlaps a part of the deodorizing means 8 when viewed from the ventilation direction of the ventilation path 6 (the direction in which air flows in the ventilation path 6 when the blowing means 7 is driven). FIG. 4 shows a facing example of the deodorizing means 8 and the heating means 9. FIG. 4 corresponds to a view of the deodorizing means 8 and the heating means 9 (heating area thereof) arranged in the main body case 1 as viewed from above.

  FIG. 4A shows a basic arrangement example of the deodorizing means 8 and the heating means 9. In the example shown in FIG. 4A, the heating means 9 has a fan shape whose outer shape has a predetermined thickness. For example, the heating means 9 is formed so that the central angle is about 90 °, and the arc portion is along the outer peripheral portion of the deodorizing means 8. That is, the heating means 9 is opposed to a quarter region of the deodorizing means 8.

  FIG. 4B shows a case where the heating means 9 has a quadrangular shape having a predetermined thickness. One apex of the heating means 9 is arranged at the center position of the circle of the deodorizing means 8. Even in such a case, the heating means 9 is opposed to a quarter region of the deodorizing means 8. The arrangement of the heating means 9 may be limited depending on the shape of the ventilation path 6 and the fixing method of the heating means 9. The arrangement shown in FIG. 4B can be an effective means when the arrangement of the heating means 9 is restricted by such a design reason.

  FIG. 4C shows a case where the deodorizing means 8 has a quadrangular shape having a predetermined thickness, and the heating means 9 has the same shape as FIG. 4B. Even in such a case, the heating means 9 is opposed to a quarter region of the deodorizing means 8. In some cases, the deodorizing means 8 cannot be driven by a design reason or the like, and the heating means 9 must be driven by the driving means. The arrangement shown in FIG. 4C can be an effective means in the case of such a restriction.

  4A to 4C show a case where the heating unit 9 faces a quarter of the area of the deodorizing unit 8. However, this opposing region is appropriately set according to the adsorption performance of the deodorizing means 8 and the oxidative decomposition performance of the deodorizing means 8 and the heating means 9.

  The shape and arrangement of the deodorizing means 8 and the heating means 9 are not limited to the above. However, the deodorizing means 8 is configured to allow at least air to pass through, and needs to include a base material that adsorbs odor components (odor substances). The heating means 9 needs to be arranged at the downstream side at least with respect to the flow direction of the air flowing through the ventilation path 6 of the deodorizing means 8. Further, the heating means 9 is configured to allow air to pass through, and needs to include a base material to which an oxidative decomposition catalyst is attached.

  The control means includes a control board provided inside the main body case 1. A control means is arrange | positioned outside the ventilation path 6, for example. The control means controls various operations in the deodorizing apparatus. The control unit is connected to the suction port 4, the blowout port 5, the blower unit 7, the deodorizing unit 8, and the heating unit 9 through wiring (not shown).

  The control unit controls the blowing unit 7 to generate an air flow in the ventilation path 6. Further, the control means controls the heating means 9 to raise the temperature of the heating means 9 and maintain a predetermined heating state.

  The control means drives the deodorizing means 8 by controlling the driving means. For example, when the deodorizing means 8 and the heating means 9 are arranged as shown in FIG. 4A, the control means controls the driving means to rotate the deodorizing means 8 about its central axis. Thereby, the opposing position with respect to the deodorizing means 8 of the heating means 9 can be changed.

  On the other hand, when the deodorizing means 8 has a shape as shown in FIG. 4C, the deodorizing means 8 is fixed to the main body case 1 or the like. In such a case, the driving unit drives the heating unit 9. The control means controls the drive means to move the heating means 9 above the deodorizing means 8 and change the position of the heating means 9 facing the deodorizing means 8. The deodorizing means 8 and the heating means 9 should just be comprised so that the relative positional relationship can be changed.

  In the operation of removing the odor component adsorbed on the deodorizing means 8, the control means closes at least one of the suction port 4 and the outlet 5, or operates the deodorizing device to remove the odor component in the deodorizing means 8. In the operation | movement which cleans room air through the air of the containing room | chamber, the suction inlet 4 and the blower outlet 5 can be opened, and it can block | close when operation | movement is completed.

Next, operation | movement of the deodorizing apparatus which has the said structure is demonstrated.
When a switch (not shown) or the like provided on the main body case 1 is operated, the control means drives the air blowing means 7. When the air blowing means 7 starts operation, indoor air is taken into the main body case 1 from the suction port 4. The air that has passed through the suction port 4 passes through the ventilation path 6 and then returned to the room from the blowout port 5. The air passes through the deodorizing means 8 when passing through the ventilation path 6. For this reason, the odor component (odor substance) contained in the air is adsorbed by the deodorizing means 8 and removed from the air. On the other hand, the deodorizing performance of the deodorizing means 8 gradually decreases in accordance with the removal of odorous components from the indoor air.

Thereafter, the deodorizing apparatus performs a recovery operation for recovering the deodorizing performance of the deodorizing means 8 at a predetermined timing. The recovery operation is controlled by the control means.
When the control unit starts the recovery operation, first, based on a predetermined heating control program, the control unit raises the temperature of the heating unit 9 to a predetermined temperature necessary for oxidative decomposition of the odorous substance. For example, the control unit determines whether or not the heating unit 9 has reached a target temperature based on a detection result of a temperature detection unit (not shown) provided in the heating unit 9. Alternatively, the control unit determines whether or not the heating unit 9 has reached a target temperature based on the time during which the heating unit 9 is heated. For example, the control means determines that the heating means 9 has reached the target temperature when the heating time of the heating means 9 reaches a predetermined time. The predetermined time is set in advance based on a temperature raising program (Δ ° C./min×min) for the heating means 9.

  When the heating means 9 reaches a predetermined temperature, the control means continues the heating state for a predetermined time. The heating temperature (temperature kept constant) and the heating time at this time are set to a temperature and a time necessary for desorbing the odorous substance from the deodorizing means 8 and oxidatively decomposing with the heating means 9.

  When the heating unit 9 generates heat, heat from the heating unit 9 propagates through the heating space and is transmitted to the deodorizing unit 8. Thereby, the deodorizing means 8 heats up. When the deodorizing means 8 is heated and reaches a predetermined temperature, the odorous substance adsorbed on the deodorizing means 8 is desorbed and is oxidatively decomposed by the oxidative decomposition catalyst supported on the surface of the heating means 9. The odorous substance rides on the rising air stream warmed by the heating means 9, passes through the heating space between the deodorizing means 8 and the heating means 9, and reaches the heating means 9. The odorous substance that has reached the heating means 9 is oxidatively decomposed by an oxidative decomposition catalyst provided in the heating means 9.

While the heating means 9 is generating heat, the air blowing means 7 is basically stopped. Even if the blowing means 7 is stopped, the odorous substance desorbed from the deodorizing means 8 rides on the ascending current and reaches the heating means 9, so that the deodorizing performance recovery operation of the deodorizing means 8 can be performed. On the other hand, if the concentration of the odorous substance is very high, or if due to design reasons, sufficient oxidative decomposition performance cannot be achieved by passing air once through the heating means 9, the heating means 9 is generating heat. The air blowing means 7 may be driven (during the recovery operation).
Since the odor component desorbed from the deodorizing means 8 can be repeatedly circulated to the heating means 9 by closing the suction port 4 and the air outlet 5 by the control means, the recovery rate of the deodorizing means 8 is improved.

  In such a case, for example, the main body case 1 is provided with closing means (not shown) for closing the inlet 4 and the outlet 5. The closing means is controlled to be opened and closed by, for example, a control means. When the recovery operation is started and the heating unit 9 generates heat, the control unit closes the suction port 4 and the outlet 5 by the closing unit. Further, when the control unit causes the heating unit 9 to generate heat and closes the suction port 4 and the blowout port 5 by the closing unit, the control unit drives the blower unit 7 to circulate the air in the main body case 1 (ventilation path 6).

When the heating state is continued for a predetermined time, the control means ends the heating control program. Thereafter (for example, when the heating means 9 cools to a predetermined temperature), the control means controls the drive means to rotate the deodorizing means 8 by a predetermined angle (90 ° in the example shown in FIG. 4). Thereby, the area | region where the deodorizing performance recovered | restored by implementation of the said heating control program among the deodorizing means 8 is arrange | positioned in the position where the heating means 9 is not arrange | positioned upwards. Further, in the deodorizing means 8, the region where the most time has elapsed since the recovery processing of the deodorizing performance is performed is arranged immediately below the heating means 9.
Thus, one recovery operation is completed.

As described above, the recovery operation is performed at a predetermined timing.
The timing for performing the recovery operation may be, for example, when the daily deodorizing operation is finished. In such a case, the deodorizing performance can be recovered in one day for a quarter region of the deodorizing means 8. On the next day, the recovery process similar to the above is performed on the area adjacent to the area where the deodorizing performance was recovered on the previous day. With such a configuration in which the one-time operation is repeated, the deodorizing performance of the entire deodorizing means 8 can be recovered in 4 days. With such a configuration, power consumption per day for performing the recovery operation can be suppressed as compared with a configuration in which the heating unit 9 is completely opposed to the entire surface of the deodorizing unit 8.

  It is also possible to perform a plurality of recovery operations on the same day (for example, after the daily deodorizing operation is completed), and to recover the deodorizing performance of the entire deodorizing means 8 in one day. This is effective when it is necessary to give priority to the recovery of deodorizing performance.

  In addition, the timing of performing the recovery operation is when the accumulated time since the start of the operation of the deodorizing device (cumulative time when the deodorizing operation is performed) exceeds a predetermined time or when the previous recovery operation is performed. It may be the case where the accumulated time from exceeds a predetermined time.

  The content of the recovery operation is determined based on various conditions such as the deodorizing performance of the deodorizing means 8 (adsorption performance for adsorbing odorous substances) and the presence or absence of catalyst attachment to the deodorizing means 8. For example, the deodorizing performance of the deodorizing means 8 is recovered before the amount of odorous substances adsorbed on the deodorizing means 8 exceeds a predetermined allowable amount.

  If it is a deodorizing apparatus which has the said structure, it can suppress that an odor substance is re-released indoors. That is, since the heating means 9 is arranged on the downstream side of the deodorizing means 8, the odorous substance desorbed from the deodorizing means 8 reaches the heating means 9 on the ascending current, and the heating means 9 (oxidative decomposition catalyst). Is oxidatively decomposed.

  In the thing of the said patent document 2, before a decomposition | disassembly part reaches predetermined | prescribed temperature, there exists a possibility that an adsorption | suction part may be heated. In such a case, the odor substance desorbed from the adsorption part passes through the decomposition part without being decomposed. For this reason, an odorous substance will be re-released indoors immediately after operating a deodorizing apparatus.

  In the deodorizing apparatus according to the present invention, a heating means 9 integrally configured with a heating element and a base material attached with a catalyst for oxidative decomposition is disposed above the deodorizing means 8, and the deodorizing means 8 is heated by the heating means 9. To do. For this reason, the base material of the heating means 9 is directly transmitted with heat from the heating element, and reaches a desired temperature in a short time (faster than the deodorizing means 8). Before the odorous substance is desorbed from the deodorizing means 8, the oxidative decomposition catalyst provided in the heating means 9 can be sufficiently activated. In particular, when the base material of the heating means 9 is made of a material (for example, metal) whose thermal conductivity is higher than that of the deodorizing means 8 (base material), the temperature of the deodorizing means 8 is It can prevent rising in a short time, and can raise the base material of the heating means 9 to desired temperature at an early stage.

  In addition, if the distance between the deodorizing unit 8 and the heating unit 9 is appropriately adjusted, heat transfer from the heating unit 9 to the deodorizing unit 8 can be suppressed.

  If it is a deodorizing apparatus of the said structure, the decomposition | disassembly efficiency of the odorous substance adsorbed | sucked to the deodorizing means 8 can be improved. The initial deodorizing performance of the deodorizing means 8, that is, the one-pass removal rate can be maintained over a long period of time. As a result, it is possible to prevent the odorous substance from being released again into the room immediately after the deodorizing apparatus is operated. For this reason, an unpleasant odor does not generate | occur | produce from a deodorizing apparatus. Moreover, after suppressing power consumption, the deodorizing performance of the entire deodorizing means 8 can be recovered, and convenience can be improved.

  In the deodorizing apparatus, the deodorizing means 8, the heating means 9, and the air blowing means 7 are arranged in order with respect to the ventilation direction. That is, the deodorizing means 8, the heating means 9, and the air blowing means 7 are arranged in parallel with the installation surface of the main body case 1 in this order from below. For this reason, even if the air blowing means 7 is not operated, the odorous substance desorbed from the deodorizing means 8 moves upward by the ascending air current, so that it can be reliably oxidatively decomposed by the heating means 9. Further, when the air blowing means 7 is operated, since the odorous substance can be in a circulating state in which the odorous substance is repeatedly contacted with the oxidative decomposition catalyst, the total time for the odorous substance and the catalyst to be in contact can be increased, and the decomposition efficiency thereof Can be improved.

  When an oxidative decomposition catalyst that is activated in a low temperature region is attached to the deodorizing means 8 (than the oxidative decomposition catalyst attached to the heating means 9), the deodorizing means 8 promotes the oxidative decomposition reaction of odorous substances that are easily decomposed. Can be made. In such a case, the heating means 9 can specially perform decomposition processing of odor substances that are difficult to decompose, and the time required for the recovery operation can be shortened. In particular, when the air blowing means 7 is operated, the time required for the recovery operation can be further shortened, and power consumption can be suppressed.

  When the base material of the heating means 9 is made of a metal having a high thermal conductivity, the temperature distribution during heating can be made uniform. For this reason, it can prevent that the dispersion | variation in decomposition | disassembly performance arises with the position (for example, distance from a heat generating body) of a base material.

Moreover, in the said deodorizing apparatus, the heating means 9 is made to oppose only a part of deodorizing means 8. FIG. For this reason, the heating means 9 can be reduced in size and power consumption can be suppressed.
Further, the heating means 9 is arranged on the downstream side of the deodorizing means 8. For this reason, even when the user replaces the dust removing means (not shown) disposed inside the main body case 1 from the suction port 4 side, the user's hand is not likely to touch the heating means 9.

Embodiment 2. FIG.
FIG. 5 is a longitudinal sectional view showing a deodorizing apparatus according to Embodiment 2 of the present invention.
In the deodorizing apparatus in the present embodiment, the configuration of the heating means 9 is different from that in the first embodiment. The function of the heating unit 9 and the configuration and operation other than the heating unit 9 are the same as those in the first embodiment.

  As shown in FIG. 5, the heating means 9 includes a heat source 10 having a predetermined heat generator, and a base material 11 to which a predetermined oxidative decomposition catalyst is attached. The heat source 10 and the base material 11 are integrally provided.

  The base material 11 is provided in the ventilation path 6. The base material 11 is disposed on the downstream side, that is, above the deodorizing means 8. The lower surface of the base material 11 faces a part of the upper surface of the deodorizing means 8. A minute heating space is formed between the deodorizing means 8 (the upper surface thereof) and the substrate 11 (the lower surface thereof). The base material 11 is formed so that air can pass through.

  The heat source 10 is provided outside the ventilation path 6. That is, the heat source 10 is not disposed in the ventilation path 6. With such a configuration, the heat retaining property of the heat source 10 can be improved, and the power consumption during the recovery operation can be suppressed. By covering the heat source 10 with a heat insulating material, the heat retaining property can be further enhanced.

  With this configuration, the heat source 10 can be arranged at a position away from the deodorizing means 8. The deodorizing means 8 is heated by the heat transmitted through both the base material 11 and the heating space. For this reason, before the odor substance is desorbed from the deodorizing means 8, the oxidative decomposition catalyst provided in the heating means 9 can be sufficiently activated. In addition, with such a configuration, it is possible to protect the wiring connected between the heating means 9 and the control means.

  If the heat source 10 is disposed outside the ventilation path 6, the heat source 10 can be configured by a non-breathable structure. Even if such a configuration is adopted, there is no possibility of causing pressure loss in the ventilation path 6. Even if the heat source 10 has a breathable structure, the heat release amount can be reduced by disposing the heat source 10 outside the ventilation path 6 and the heating efficiency can be improved.

Embodiment 3 FIG.
6 is a longitudinal sectional view showing a deodorizing apparatus according to Embodiment 3 of the present invention.
In the deodorizing apparatus in the present embodiment, the shape (path) of the ventilation path 6, the arrangement of the suction port 4, the deodorizing means 8, and the heating means 9 are different from those in the first or second embodiment. Other configurations and operations are the same as those in the first or second embodiment.

  The suction port 4 is formed on one side surface of the main body case 1. In the present embodiment, the suction port 4 is formed in the lower part of the front cover 2.

  The ventilation path 6 is formed in L shape, for example. The air passage 12 on the upstream side of the air passage 6 is formed in the horizontal direction from the suction port 4 inside the main body case 1. The air passage 13 on the downstream side of the air passage 6 is formed in the vertical direction from the air outlet 5 inside the main body case 1. That is, when the blowing means 7 is driven, the air taken in from the suction port 4 first proceeds in the horizontal direction in the air passage 12. When the air passes through the air passage 12, the air flow direction is changed and the air travels upward in the air passage 13. The air that has passed through the air passage 13 is discharged from the air outlet 5.

  The deodorizing means 8 is provided in the upstream air passage 12 in the ventilation passage 6. The deodorizing means 8 is arranged perpendicularly to the ventilation direction of the air passage 12. In this Embodiment, the deodorizing means 8 is arrange | positioned in the air path 12 perpendicular | vertical with respect to the installation surface of a deodorizing apparatus (main body case 1).

  The heating means 9 includes a heat source 10 having a predetermined heating element, and a base material 11 to which a predetermined oxidative decomposition catalyst is attached. The heat source 10 and the base material 11 are integrated. The base material 11 is provided in the air flow path 13 on the downstream side of the air flow path 6. The base material 11 (heating means 9) is disposed perpendicular to the ventilation direction of the air passage 13. In this Embodiment, the base material 11 is arrange | positioned in the air path 13 in parallel with respect to the installation surface of a deodorizing apparatus (main body case 1). The heat source 10 is provided outside the ventilation path 6. That is, the heat source 10 is not disposed in the ventilation path 6. The heating means 9 may have the configuration shown in the first embodiment.

  The heating means 9 is not opposed to the deodorizing means 8 and is disposed at a position away from the deodorizing means 8. In the deodorizing apparatus having such a configuration, for example, the blowing unit 7 is driven while the heating unit 9 is generating heat (during the recovery operation). For this reason, the main body case 1 is provided with closing means (not shown) for closing the suction port 4 and the air outlet 5. The closing means is controlled to be opened and closed by the control means, for example. When the recovery operation is started and the heating unit 9 generates heat, the control unit closes the suction port 4 and the outlet 5 by the closing unit. Further, when the control unit causes the heating unit 9 to generate heat and closes the suction port 4 and the blowout port 5 by the closing unit, the control unit drives the blower unit 7 to circulate the air in the main body case 1 (ventilation path 6).

  Since the heating means 9 is disposed at a position away from the deodorizing means 8, the amount of heat propagation per unit time can be reduced. For this reason, the temperature of the deodorizing means 8 does not rise in a short time, and the oxidative decomposition catalyst provided in the heating means 9 can be sufficiently activated before the odorous substance is desorbed from the deodorizing means 8. .

  Moreover, since the deodorizing means 8 is arranged perpendicular to the installation surface, the installation surface can be made smaller and the deodorization apparatus itself can be downsized. Even users who cannot secure a large space for the deodorizing device can be used, and convenience is improved.

In the deodorizing apparatus shown in FIG. 6, the same effect as described above can be obtained regardless of whether the heating means 9 is arranged parallel or perpendicular to the installation surface.
When the heating means 9 is arranged in parallel to the deodorizing means 8, the heating means 9 has, for example, a cross-sectional area (area in a direction orthogonal to the ventilation direction) in the ventilation path 6 as in the present embodiment. The deodorizing means 8 is disposed in a portion smaller than the cross-sectional area of the portion. With this configuration, the deodorizing device can be downsized.

  The structure shown in Embodiments 1 to 3 can be applied to an air purifier or an air conditioner having a deodorizing function. In addition, for example, the present invention can be applied to an apparatus for the purpose of deodorizing water or garbage.
