  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
As shown in FIG. 1, the deodorizing device 1 is installed at the upper part of the room, and has a louver 2 at the lower part of the main body case 1a. The louver 2 has a suction port 3 and an air outlet 4, and ions 5 generated inside the deodorizing device 1 are supplied to the room as described later.

  The ions 5 supplied into the room purify the indoor air and make contact with a not-shown object (for example, a odor-attached cloth or the like) to exert an effect on the object (for example, a odor-attached cloth). Deodorization) can be obtained.

  FIG. 2 shows the internal structure of the deodorizing device 1 when the louver 2 is directed downward. The deodorizing device 1 includes a filter unit 6 above the louver 2 inside the main body case 1a. The filter unit 6 houses an adsorption filter 9 inside a storage space formed by a case 7 and a lid 8. As will be described later, the adsorption filter 9 is a filter carrying an adsorbent and adsorbs and removes odor components and the like contained in the air to be treated.

  A blower 14 including a motor 12 and a fan 13 is provided inside the main body case 1 a above the filter unit 6. The broken arrows indicate the flow of the air to be processed, and the air to be processed sucked into the main body case from the suction port 3 by the action of the blowing means 14 passes through the auxiliary filter 10 and the filter unit 6 as a suction path. After passing through the auxiliary filter 10 again as a blowing path, the air is supplied from the blowing port 4 into the room. The auxiliary filter 10 is a dust collecting filter, and collects and removes dust and the like contained in the air to be processed.

  An electrostatic atomizer 11 is provided inside the deodorizer 1. The electrostatic atomizing means 11 includes a discharge electrode (not shown), a counter electrode (not shown) arranged opposite to the discharge electrode, and a high-voltage applying unit (not shown) that applies a high voltage between the discharge electrode and the counter electrode. A cooling unit (not shown) that cools the discharge electrode is provided.By cooling the discharge electrode by the cooling unit, moisture in the air is condensed on the tip of the discharge electrode, and a high voltage is applied to the condensed water to apply a negative voltage. Means for concentrating the electric charges to generate and atomize negatively charged charged fine particle water, and to obtain charged fine particle water having a disinfecting effect and a deodorizing effect corresponding to the ion 5 shown in the present embodiment. It is. The ions 5 generated by the electrostatic atomizing means 11 inside the deodorizing device 1 are supplied from the outlet 4 to the room.

  The electrical board 15 receives supply of commercial power from indoor electric wiring (not shown) to supply power to the electrostatic atomizing means 11 and the motor 12 and control the operation.

  FIG. 3 shows a fitting state between the filter unit 6 and the main body case 1a. The filter unit 6 has a projection 7 a on the side of the case 7 near the louver 2. In addition, the claw 7b provided on the side surface of the case 7 is fitted into the slit 16 opened in the partition 17 provided on the inner periphery of the main body case 1a, thereby fixing the filter unit 6.

  FIG. 4 shows a bottom view of the deodorizing device 1. The louver 2 has a suction port 3 and a blow-out port 4, and the auxiliary filter 10 having a dust collecting action can be confirmed from the openings of the suction port 3 and the blow-out port 4.

  FIG. 5 shows a component assembly diagram of the filter unit 6. The suction filter 9 in which the base material 9a is wrapped by the net 9b is housed in a frame-shaped case 7 having a large number of openings, and is similarly fixed by a frame-shaped lid 8 having a large number of openings. That is, the air to be processed can pass through the case 7, pass through the net 9 b, come into contact with the base material 9 a, and further pass through the lid 8.

  FIG. 6 shows a structure in which the adsorbent 9c is supported on the base material 9a of the adsorption filter 9. The adsorbent 9c is a granular material having a high adsorption action such as activated carbon or zeolite, and is adhered and fixed to the base material 9a with an adhesive or a resin. Since the base material 9a is a net-like member and the adsorbent 9c is supported and fixed with a space therebetween, it does not hinder the flow of the air to be treated.

  FIG. 7 shows an arrangement of the filter unit 6 inside the deodorizing device 1. As described with reference to FIG. 3, the filter unit 6 can be fixed by fitting the claw 7b into the slit 16 opened in the partition 17 provided in the inner casing of the main body case 1a.

  The plurality of pawls 7b are provided on the side surface of the filter unit 6, and each of them is fitted into the slit 16, so that the filter unit 6 can be installed at a predetermined position, and the dropout from the main body case 1a can be suppressed. . The filter unit 6 is similar to a columnar structure similar to the inner peripheral surface of the partition 17, but has a recess 7c for avoiding interference with a functional member present inside the partition 17 in the main body case 1a. ing.

  Since the area of the lower surface (louver side) is smaller than the upper surface (blower side) of the filter unit 6, the side surface of the filter unit 6 is inclined toward the lower surface. Due to its shape, the angle of change in the flow direction of the air to be treated flowing from the suction port 3 provided in the louver 2 of the deodorizing device 1 when passing through the side surface of the filter unit 6 is obtuse, so that the flow of the air to be treated is Resistance can be reduced.

  Further, by making the area of the lower surface (louver side) smaller than the upper surface (blower side) of the filter unit 6, the side surface of the filter unit 6 is inclined in the lower surface direction. When the filter unit 6 is mounted, the operator can easily grasp the side surface of the filter unit 6 and the workability is improved.

  The louver 2 is pressed and fixed to the main body case 1a by a clip having a latch structure (not shown). After the louver 2 is temporarily placed at a predetermined position on the main body case 1a, the louver 2 is pressed in the direction of the main body case 1a. By doing so, the latch structure of the clip (not shown) is fastened, and the louver 2 can be fixed to the main body case 1a. When removing the louver 2 from the main body case 1a, the latch structure of the clip (not shown) is released by pressing the louver 2 toward the main body case 1a in the same manner as when the louver 2 is mounted, and the louver 2 can be removed.

  The auxiliary filter 10 is a dust collecting filter having fine pores made of planar fibers, and removes dust and the like contained in the air to be treated by the action of physical filtration.

  FIG. 8 shows a state in which the filter unit 6 is held in a non-fitted state inside the main body case 1a, and the louver 2 and a part of the projection 7a are in contact with each other. As described above, the filter unit 6 is provided with a plurality of claws 7b on the side surface, and the substantial outer diameter of the filter unit 6 including the plurality of claws 7b is larger than the substantial inner diameter of the partition 17. . Further, the pawl 7b is provided on the side surface of the filter unit 6 so that the connection portion with the filter unit 6 is elastically deformable. Therefore, the base of the pawl 7b is reduced and deformed inward of the filter unit 6. It is also possible to hold the main body case 1a in a non-fitted state inside. Therefore, in FIG. 8, the pawl 7b is not engaged with the slit 16 of the partition part 17, but the frictional resistance of the pawl 7b and the surface of the partition part 17 and the partition caused by the restoring force of the elastic deformation of the base part of the pawl 7b The filter unit 6 is held by the reaction force of the portion 17 toward the surface.

  In the state shown in FIG. 8, since there is a gap between the filter unit 6 and the partition 17, when the deodorizing device 1 is operated in this state, the air to be treated sucked into the deodorizing device 1 causes the filter unit 6 to operate. The air may not pass through the gap between the filter unit 6 and the partition 17 and may not be able to exhibit the original air purification performance.

  Since the filter unit 6 is in a non-fitting state and is not fixed at a predetermined position in the main body case 1a, when the louver 2 is pressed and fixed in this state, the louver 2 and the projection 7a of the filter unit 6 come into contact with each other. FIG. 8 shows a state in which the louver 2 is pressed in the direction of the arrow by an operator (not shown), and the louver 2 presses the filter unit 6 in the direction of the arrow.

  A part of the auxiliary filter 10 is held between the louver 2 and the main body case 1a with a part thereof sandwiched between the partition 17 and the partition 2a.

  FIG. 9 shows an enlarged view around the pawl 7b in a state where the filter unit 6 moves from the non-fitting state to the fitting state. By pressing the louver 2 in the direction of the main body case 1a, the projection 7a of the filter unit 6 is pressed, and the filter unit 6 moves inside the partition 17 upward. The state is shown in which the pawl 7b moves upward along the inner peripheral surface of the partition portion 17 and approaches the slit 16. The cross-sectional structure of the pawl 7b is thinner at the tip portion near the slit 16 than at the portion far from the slit 16, and the cross-sectional structure of the slit 16 is wider at the entrance portion closer to the pawl 7b than at the portion farther from the pawl 7b. With such a structure, when a part of the tip of the pawl 7b starts to be fitted from below the slit 16, the pawl 7b moves upward so as to push up inside the slit 16. As a result, the filter unit 6 is also moved upward by being pulled by the pawl 7b. Therefore, as shown in FIG. 9, if the filter unit 6 is disposed to a position where a part of the pawl 7 b starts to be fitted into the slit 16, the pawl 7 b moves the filter unit 6 to a predetermined position by an upward movement. Can be fixed.

  FIG. 10 shows a state in which the filter unit 6 is engaged and fixed at a predetermined position. The pawl 7b is fitted into the slit 16, and it can be seen that the filter unit 6 has moved upward as compared with the state of FIG. When the claw 7b of the filter unit 6 is fitted into the slit 16, the louver 2 does not contact the projection 7a.

  FIG. 11 shows a state where the filter unit 6 is engaged and fixed at a predetermined position. The lid 8 of the filter unit 6 is close to an orifice 18 corresponding to a suction portion of the blowing means 14. As described above with reference to FIG. 5, the filter unit 6 includes the frame-shaped case 7 having a large number of openings and the lid 8 so as to enclose and hold the adsorption filter 9. The air to be treated sucked into 1a is sucked into the filter unit 6 from the surface of the filter unit 6 having the projection 7a and the side surface on which the pawl 7b extends, passes through the lid 8, passes through the orifice 18, It will be sucked.

  Of the plurality of protrusions 7a, the protrusion 7a closer to the partition 17 penetrates a part of the auxiliary filter 10 and is fixed. As a result, the auxiliary filter 10 is fixed at a predetermined position between the louver 2 and the filter unit 6. As shown in FIG. 7 earlier, the auxiliary filter is a dust collection filter having fine holes made of planar fibers, so that when the louver 2 is pressed and fixed to the main body case 1a, the louver is used. 2 and the filter unit 6 are compressed in the thickness direction. Since the projection 7a penetrates a part of the auxiliary filter 10 and is fixed, the auxiliary filter 10 can be prevented from moving in a plane direction or rotating.

  Further, as shown in FIG. 7 earlier, the auxiliary filter 10 is assumed to be a single planar fiber, but a part thereof is sandwiched between the partition 17 and the partition 2a as shown in FIGS. Have been. As a result, the auxiliary filter 10 covering the suction path of the suction port 3 functions as a pre-filter of the filter unit 6 and the auxiliary filter 10 covering the discharge path of the blow-out port 4 while being one continuous flat fiber. Can function separately as post filters. As a function of the post filter, an effect of suppressing dust and the like accumulated in the main body case 1a for some reason from re-scattering into the room due to the operation of the deodorizing device 1 can be expected.

  Even if the dust collected by the auxiliary filter 10 covering the suction path of the suction port 3 moves inside the auxiliary filter 10, the fiber constituting the auxiliary filter 10 is located between the partition 17 and the partition 2a. Are compressed, and the fine holes are reduced, so that dust is prevented from passing through the holes and moving to the auxiliary filter 10 covering the blowing path of the outlet 4.

  If maintenance of the filter unit 6 is necessary with the elapse of the operation time of the deodorizing device 1, after the louver 2 is detached from the main body case 1a, the root of the pawl 7b is pushed toward the center of the filter unit 6 to be deformed. Then, the engagement between the pawl 7b and the slit 16 is released, so that the filter unit 6 can be easily detached from the main body case 1a.

  FIG. 12 shows a state where the filter unit 6 is engaged with the slit 16 and fixed at a predetermined position. As described above with reference to FIG. 11, since the filter unit 6 is installed close to the orifice 18 corresponding to the suction portion of the blowing unit 14, vibration generated by the blowing unit 14 during operation of the deodorizing device 1 is generated. It may be transmitted to the filter unit 6. As shown in FIG. 12, when the filter unit 6 is engaged and fixed at a predetermined position, the plurality of protrusions 7 a do not contact the louver 2, and the vibration generated by the blower 14 is transmitted to the louver 2. Can be suppressed.

  According to such a configuration, when the filter unit 6 is mounted in the main body case 1a of the deodorizing device 1 installed at a relatively high place such as a ceiling or a wall in a room, the filter unit 6 is elastically deformed by the claws 7b. Therefore, even if the louver 2 is pressed and fixed, the filter unit 6 is moved to a predetermined position and fixed by fitting even if the inner peripheral portion of the partition portion 17 is fixed in an insufficiently fitted state.

  Also, the louver 2 is in contact with the projection 7a of the filter unit 6 only during the pressing operation. When the filter unit 6 is fitted into the slit 16, the louver 2 does not contact the projection 7a. The possibility that the vibration from the means 14 is transmitted to the planar louver 2 to generate noise can be suppressed. Since the louver 2 has a function of a decorative panel of the deodorizing device 1, it is always mounted when the deodorizing device 1 is operated. Therefore, the operation of pressing and fixing the louver 2 is always performed before the operation of the deodorizing device 1, and it can be expected that the filter unit 6 is reliably fixed at a predetermined position.

  In the present embodiment, the filter unit 6 has a deodorizing function and the auxiliary filter 10 has a dust collecting function. However, the present invention is not limited to this configuration, and the filter unit 6 itself may have a dust collecting function. Also, the auxiliary filter 10 may have a deodorizing function. Regardless of the functions of the filter unit 6 and the auxiliary filter 10, the same effect can be obtained as long as the louver 2 presses the filter unit 6 so that the filter unit 6 moves.

  According to the present embodiment, the filter unit 6 fixed in an insufficiently fitted state is pressed by the louver 2 and fixed at a predetermined position in the main body case 1a. It may be fixed at a predetermined position by pressing in the direction of 1a. In this case, even if the louver 2 is fixed, the projection 7a of the filter unit 6 does not come into contact with the louver 2, and the vibration from the blowing means 14 is transmitted to the planar louver 2 during operation of the deodorizing device 1, so that noise is generated. Can be suppressed.

  In the present embodiment, the deodorizing device 1 is installed on the ceiling of the room, and the filter unit 6 and the louver 2 are installed from below the room. However, the present invention is not limited to this installation method. And the filter unit 6 and the louver 2 may be installed from the room toward the wall surface. Similarly, by pressing the louver 2, the filter unit 6 is moved to a predetermined position and fixed by fitting. Thus, the original purification performance of the deodorizing device 1 can be obtained. It is preferable that the deodorizing device 1 is installed in the upper part of the room such as a ceiling or a wall surface near the ceiling. However, the present invention is not limited to this.

  In the present embodiment, the louver 2 is fixed to the main body case 1a by a clip having a latch structure. However, the present invention is not limited to this method, and a spring member having a winding portion at the center is provided on the louver 2. Then, the spring member in a state where the winding portion is compressed and deformed by pinching the end portion is inserted into a mounting hole opened in the main body case 1a, and the louver 2 is connected to the main body case 1a by the restoring action of the winding portion of the spring member. May be used. A similar effect can be obtained as long as the force in the direction in which the louver 2 is pressed against the main body case 1a is transmitted to the filter unit 6, and the filter unit 6 is pressed and fitted and fixed at a predetermined position.

  Since the deodorizing device according to the present invention can fix the filter unit, which is an air purifying unit, in a manner that suppresses falling while being easily detachable, it can be used as a deodorizing device widely used for deodorizing indoor air, removing bacteria, and the like. Useful.
