Then, the dust-removed air flows backward, reaches the deodorizing unit 60, and passes through the opening 65a to reach the deodorizing element 62 disposed at a position facing the opening 65a. The deodorizing element 62 forms a plurality of openings in the shape of a honeycomb from the front surface to the back surface, and applies a catalyst that adsorbs odor to the surface.

Therefore, when the odor-containing air passes from the front side to the back side of the deodorizing element 62, the honeycomb-coated opening absorbs the odor contained in the air by the catalyst applied to the deodorizing element 62, and is removed from the air. Stinky.

Further, "the odor is removed from the air" is a state in which the air is completely odorless, and the odor is reduced in a state in which the odor is lower than the state before the air passes through the deodorizing element 62.

Here, by continuously operating the air cleaner A as described above, the adsorbed odor is gradually accumulated in the deodorizing element 62, and the deodorizing performance of the deodorizing element 62 is increased as the inhaled odor is increased. Gradually decreases.

Then, the air from which the dust and the odor are removed flows from the deodorizing element 62 to the rear, passes through the rear opening 24 opened by the partition 23 of the front outer casing 20, and then flows to the air blowing fan that faces the rear opening 24. 44 flows.

The air that has flowed into the blower fan 44 flows from the front side in the axial direction of the blower fan 44 to the inside of the fan opening 44d surrounded by the vane 44a, and flows in the radial direction of the blower fan 44 including the blower fan 44 and the blower fan 44. External discharge.

The air discharged from the blower fan 44 is guided to the rear casing 40 by the partition plate 45, and when the louver 46 passes through the louver 46, the air direction is aligned, and the air blower outlet 42 is directed upward from the air cleaner A from the inside of the air cleaner A. It is blown out as clean air.

In this manner, the air passage R is connected from the air intake port 11 to the rear portion of the air cleaner body in the horizontal direction, and the direction is changed to the upper portion and then to the air passage of the air outlet port 42 in the rear portion.

In other words, when the air passage R is based on the flow of the air, the filter for filtering dust such as the front filter 13 or the HEPA filter 12 is disposed on the upstream side of the deodorizing element 62 and on the downstream side of the deodorizing element 62. The formation is a curved portion that changes the flow direction of the air to a position that is curved upward. A multi-blade fan that is a blower fan 44 is located at the bent portion.

Because the multi-blade fan draws in air from the direction of the rotating shaft of the fan and discharges the taken air in the radial direction of the fan, so that the indoor air is generated from The front side of the main body casing C flows linearly toward the rear, and the wind direction can be changed more efficiently toward the air outlet 42.

Further, the front faces of the openings 44d of the deodorizing element 62, the front filter 13, the HEPA filter 12, and the blower fan 44 are disposed in a direction perpendicular to the direction of the air flowing through the air passage R.

Therefore, since the flow of air to the deodorizing element 62 is straight and the air vertically collides with the respective filter faces, it is a configuration in which the flow of air is good.

Here, the position of the opening 65a is located at the center in the lower direction of the front surface of the main body casing C, and the relationship between the projected area X of the front outer casing C and the area Y of the front surface of the opening 65a becomes Y≧0.6X.

Next, as described above, an operation (regeneration operation) for recovering the deodorizing performance of the deodorizing element 62 that degrades the deodorizing performance by adsorbing a lot of odors by performing an air cleaning operation (deodorizing operation) is described.

The control unit 47 performs the deodorizing performance recovery operation as described below at a predetermined timing, for example, when the cumulative operation time from the start of operation or the deodorizing performance recovery operation of the deodorizing element 62 that has been performed last time exceeds a predetermined time.

When the air blowing fan 44 is stopped, that is, after the air cleaner A finishes the air cleaning operation or the air cleaning operation is not performed, the control unit 47 energizes the heater unit 63a to cause the heater unit 63a to generate heat. The portion of the deodorizing element 62 that faces the heater unit 63a rises to a predetermined temperature and is heated for a predetermined period of time.

The heating temperature and heating time of the deodorizing element 62 are sufficient to remove the temperature and time of the odor adsorbed by the deodorizing element 62.

Further, since the front side of the heated portion of the deodorizing element 62 is covered by the lid body 65d which has been coated with the heat radiation rate, the rear side is covered by the heating unit 63 (heater unit 63a). Therefore, the deodorizing element 62 can be efficiently heated by the heat generated from the heater unit 63a and the heat radiated from the lid body 65d.

Further, since the deodorizing element 62 is located at a position sandwiched by the heater unit 63a and the lid 65d, heat radiated from these members is easily accumulated in the vicinity of the deodorizing element 62, and the deodorizing element 62 can be more efficient. Ground heating.

Then, as described above, when the deodorizing performance recovery operation in the portion facing the heating unit 63 is completed, the control unit 47 operates the driving means 64 for rotating the deodorizing element 62, and the deodorizing element 62 is rotated only. angle.

By this operation, the portion where the heat treatment of the deodorizing element 62 with respect to the heating unit 63 is completed is shifted with respect to the heating unit 63.

Thereby, the portion of the deodorizing element 62 whose heat treatment is completed is separated from the position where the heating unit 63 and the lid body 65d are sandwiched, and the new portion of the deodorizing element 62 that adsorbs a lot of odor is located in the heated unit 63 and the lid body. 65d clamped position.

Further, the angle at which the deodorizing element 62 is rotated may be the same as the opening angle of the fan-shaped heater unit 63a or an angle smaller than the opening angle. By setting the rotation angle in this manner, in the one rotation of the deodorizing element 62, any portion of the deodorizing element 62 is always stopped before the heater unit 63a, and is subjected to heat treatment.

Moreover, the timing of driving the deodorizing element 62 can also be performed after the heat treatment. Going up, it can also be done before the next air clean run is about to begin.

Next, the deodorizing unit 60 will be described with reference to Figs. 11 to 12 .

The deodorizing portion 60 is located at a lower portion of the central support body 65b that is located at the center of the inner portion of the opening 65a of the partition plate 65 in the deodorizing portion 60, and is opened at a predetermined opening angle by the center support body 65b. The formed fan-shaped region is covered by the substantially fan-shaped cover 65d from the back side of the intermediate partition 65.

The lid body 65d is formed of stainless steel, and is fixed to the beam portion 65c by screws or the like from the rear side (back side) of the intermediate partition plate 65. Moreover, the lid body 65d is in a state of being opposed to the heater unit 63a of the heating unit 63 to be described later, and is sized to cover the heater unit 63a.

Further, in a state in which the lid body 65d is attached as described above, the heat insulating material 66 is provided at a portion surrounded by the front surface of the lid body 65d and the beam portion 65c. Further, a cover 67 is provided on the front side of the heat insulating material 66. The cover 67 is formed of a resin, and is fixed to the beam portion 65c by screws or the like from the front side (surface side) of the intermediate partition plate 65.

When the respective portions are configured as described above, since the front surface of the lid body 65d is covered with the heat insulating material 66, when the deodorizing member 62 is heated by the heating unit 63, the heating space can be made thermally difficult by being opposed to the heating unit 63. The surface of the lid body 65d that forms the heating space is spread.

Therefore, since the temperature of the heating space can be efficiently increased, the deodorizing element 62 can be efficiently heated, and the user does not directly contact the high-temperature lid 65d, so that burns can be prevented.

Next, the air outlet 42 will be described with reference to Figs. 13 to 14 . In addition, In the drawings from Fig. 13 to Fig. 14, the lattice is generally attached to the opening portion of the air outlet 42. However, in order to explain the operation of the louver 46, the lattice is removed.

First, in the vicinity of the air outlet 42, the louver 46 is composed of the following members, a plurality of plate-shaped wind direction plates 46a, and a link mechanism 46c that connects the plurality of wind direction plates 46a and rotates the wind direction plate 46a to The predetermined angle; and a driving portion (not shown) drive the link mechanism 46c.

Further, the louver 46 is arranged such that the plurality of flap-shaped wind direction plates 46a and the opening of the air outlet 42 are arranged at a predetermined interval, and the respective wind direction plates 46a are formed on the both ends of the wind direction plate 46a. The shaft is supported by the air outlet 42.

Further, the drive unit of the drive link mechanism 46c is connected to a control unit 47, which will be described later, and is driven by a predetermined program in accordance with the state of the air cleaner, thereby changing the direction of the louver 46.

Further, the width of the wind direction plate 46a is substantially the same as the width in the front-rear direction of the air outlet 42, and the maximum width in the left-right direction is in a state in which the louver 46 is closed, that is, the state in which the wind direction plate 46a is fallen, by the adjacent The wind direction plate 46a is configured to cover the extent of the air outlet 42.

Further, the louver 46 is configured to operate the driving portion of the drive link mechanism 46c between the heat treatment of the deodorizing element 62, so that the respective wind direction plates 46a cover the air outlet 42 and are in a fallen state.

In this manner, between the heat treatment of the deodorizing element 62, the air outlet 42 is closed by the louver 46, whereby it is difficult to release the odor from the deodorizing element 62 generated during the heat treatment to the outside of the air cleaner A. Taste and so on.

In the present embodiment, the configuration in which the air outlet 42 is closed by the louver 46 provided in the air outlet 42 is described. However, a shutter such as the opening and closing air outlet 42 may be provided separately from the louver 46.

Further, not only the air outlet 42 but also a shutter or the like that opens and closes the opening of the suction port 11 is provided in the suction port 11, and when the suction port 11 is closed during the heat treatment of the deodorizing element 62, it is more difficult to apply to the air cleaner A. The odor or the like from the deodorizing element 62 generated during the heat treatment is externally released.

Next, the body casing will be described with reference to Figs. 15 to 17.

The air cleaner A of the present embodiment is composed of various functional components such as a main body casing C constituting the outer casing and a deodorizing portion 60 provided in the main body casing C.

The main body casing C is formed of a resin and is composed of a plurality of components such as the front panel 10, the front outer casing 20, and the rear outer casing 40, and the front and side planar shapes form a longitudinally rectangular outer casing shape.

Further, at the bottom of the main body casing C, four wheels 90 are provided. Two wheel systems are provided at the bottom of the front outer casing 20, two are disposed at the bottom of the rear outer casing 40, and when the main body casing C is viewed from the front side, The center of the main body casing C is symmetrical in the left-right direction, and is disposed one on each of the left and right sides.

Further, a handle 91 held by the user when moving the air cleaner A is provided on the rear side of the upper portion of the upper side of the frame 21 constituting the front outer casing 20.

The handle 91 is formed in a rod shape, and is disposed such that the central axis of the grip portion 91a is located at the center of the top surface of the body casing C and faces the left-right direction. The position of the handle 91 in the front-rear direction relative to the main body casing C is located between the heating unit 63 and the blower fan 44. Moreover, the distance of the grip portion 91a is from the floor surface The height L is configured to be in a range of 700 mm or less.

In the state in which the respective portions are arranged in this manner, the wheel 90 is configured to be rotatable at least in the longitudinal direction of the grip portion 91a.

As described above, the main body casing C is rotatably provided in the longitudinal direction of the grip portion 91a of the handle 91, so that even the large air cleaner A can be easily pushed and pulled.

In particular, since the front and rear positions of the main body casing C of the handle 91 are located between the heating unit 63 and the blower fan 44, the handle 91 is located at a substantially intermediate position of the portion where the weight density is large. As a result, when the handle 91 is gripped and the air cleaner is pushed and pulled, the air cleaner A can be moved with the position at which the weight balance can be relatively obtained as a fulcrum.

Therefore, it is possible to manufacture the air cleaner A which is easy to carry by the user.

Further, the air cleaner A of the present embodiment is configured such that the height L of the grip portion 91a of the handle 91 from the floor surface is 700 mm or less.

In this way, the average of the Japanese adult finger node (the vertical distance from the floor surface to the middle finger node in the state where the person stands on the floor surface) is about 695 mm for men and 632 mm for women. 662mm, so regardless of gender, the user does not have to bend too much to become the height of the handle 91 that is easy to grip.

Further, the depth S of the air cleaner A of the present embodiment is about 300 mm.

In this way, because the average shoulder width of a Japanese adult is about 426 mm for men, 394 mm for women, and 409 mm for the whole, it is not related to gender. When pushing the air cleaner A from the side, it is located on the shoulder of the person. Wide range.

Thereby, the air cleaner A can be easily moved even in a narrow passage or place.

Further, since the width of the corridor of the general home is about 850 mm to 900 mm, it is possible to secure a space of about 550 mm to 600 mm when the air cleaner A is placed in the corridor in the lateral direction.

Therefore, even if the air cleaner A is installed in the corridor of a general home, it is possible to secure a space in which a person or an object can pass.

Further, since the corridor width of the care facility is about 1800 mm or more, it is possible to secure a space of about 1500 mm when the air cleaner A is placed in the corridor in the lateral direction.

Therefore, even if the air cleaner A is placed in the corridor of the care facility, it is possible to ensure a space in which a person or a person can pass.

Moreover, since the wheelchair used in general is about 700 mm, even if the air cleaner A is installed in the corridor of the care facility, the wheelchairs can be misplaced.

By forming the respective portions of the air cleaner A as described above, the effects as described below can be obtained.

As described in the present embodiment, since the portion where the deodorizing element 62 always faces the heating unit 63 is a limited portion, the heating unit 63 can minimize the interference of the flow of the air flowing through the deodorizing element 62. . Thereby, more air can be caused to flow to the deodorizing element 62, and more odor can be removed from the air at one time.

Further, since the relative positional relationship between the deodorizing element 62 and the heating unit 63 can be changed, the heating unit 63 and the respective portions of the deodorizing element 62 can be surely opposed to each other and heated.

Thereby, the heating unevenness between the respective portions of the deodorizing element 62 can be made small, and the deodorizing performance of the deodorizing element 62 can be efficiently recovered.

Further, since the heating unit 63 is configured to cover the heater 63g that heats the heating unit 63f by the fan-shaped heating unit 63f and the heater casing 63b, even if the charging unit (current-carrying unit) of the heater 63g is ignited, Will be burned to the outside.

Further, in the case where the PTC heater is used for the heater 63g, the PTC heater has self-temperature controllability, and the temperature does not rise above the fixed temperature, since the temperature control from the outside is not required, and the intermittent control is not performed like a thermostat. So there is no spark or noise, but it can be used steadily.

Further, in the case of using the sheath heater, since the sheath heater is excellent in insulation, it can be used in the vicinity of the heating portion 63f made of a metal. In particular, in the case where the heating portion 63f of the sheath heater is cast, the heating portion 63f can be heated more efficiently.

Further, since the filter for filtering dust is provided on the upstream side of the deodorizing element 62 in the air passage, dust is hardly accumulated in the deodorizing element, and the risk of the dust being zoomed or ignited by the heat of the heater is reduced.

Further, since it is provided to detect the presence or absence of the detection switch for the filter for filtering the dust, the filter cannot be operated without the filter for filtering the dust. Thereby, since the dust can be prevented from adhering to the deodorizing element, the risk of the dust being zoomed or ignited by the heat of the heater is reduced.
