However, since the air purifying device described in the prior art document has a deodorizing portion having an adsorbent for adsorbing an odor component in the vicinity of the air blowing port formed on the upper portion of the upper surface of the main body casing, it is necessary to take off The odor is disposed in a narrow and limited area, and it is difficult to use an absorbing material having a deodorizing performance and a large odor.

Therefore, in such a configuration, even if the indoor air is passed through the deodorizing unit, it is difficult to remove the odor greatly at a time, so that the odor of the indoor air can be reduced, and it is necessary to operate the air cleaner for a long time.

Further, since the air blowing outlet opening area is much smaller than the air suction port, the flow rate of the air flowing through the air blowing port and the deodorizing portion provided near the air blowing port is much longer than the flow rate of the air flowing near the air suction port. fast.

Therefore, in such a configuration, in a state where the adsorbent material is not sufficiently adsorbed to the odor contained in the indoor air flowing in the deodorizing portion, air is discharged from the air cleaner to the room, and the odor of the indoor air can be felt to be reduced. It is necessary to make the air cleaner run for a long time.

Further, since the heater of the heating portion that removes the odor adsorbed by the adsorbent by heating the adsorbent is fixedly disposed to the adsorbent, a portion where the heater is close to the adsorbent and a portion distant from the heater are formed.

Thereby, the portion close to the adsorbent material of the heater is capable of being removed at a high rate, so that the odor can be removed, but the portion of the adsorbent material away from the heater may not be efficiently conducted from the heat of the heater, but has no The possibility of odor is completely removed.

Moreover, even if the handle is set at a height that is easy to grip, it is feared that it is difficult to grasp a person whose average height is low.

Further, since the surface of the deodorizing portion is coated or immersed in the catalyst for adsorbing the odor, the catalyst may be peeled off from the deodorizing portion and fall inside the body due to vibration such as movement. Therefore, it is possible to release the peeling catalyst from the air outlet.

Further, in order to detachably mount the filter disposed on the upstream side of the deodorizing element, the frame is disposed in front of the body casing, but may be shaken by vibration of the movement or the like due to fluctuations in the size of the body or Get rid of.

Further, in a state in which the vibration sensor that detects the falling over is placed in the main body in order to avoid a state in which it is dangerous to fall over during operation, it is possible to detect a weak vibration in normal times.

Further, in moving the body with the casters, it may fall over due to the power cord being stepped on.

The present invention has been made in order to solve the problems as described above, and an object thereof is to provide an air cleaner which can efficiently reduce the odor of indoor air and which can efficiently perform the function of adsorbing an odor-absorbing material. Restore and make it easy to move.

In order to solve the above-described problems, the air cleaner may be configured as follows, including a main body that forms a suction port and an air outlet that opens toward the outside, and a ventilation passage that communicates the suction port with the air outlet; The system is built in the body, and introduces indoor air into the air passage from the suction port to the air outlet; the deodorizing element is disposed in the air passage, and the introduced air can pass; the heating unit locally heats the deodorizing element The position changing means changes the relative positional relationship between the heating unit and the deodorizing element; and the control means controls the energization of the air blowing means, the heating means and the position changing means; and the deodorizing element is configured to be heated by the heating means. The deodorizing function is restored; at the bottom of the body casing, there are a plurality of wheels; in the upper part of the body casing, there is a handle, and the handle has a rod-shaped grip; the grip portion of the handle is formed to be long in the left and right direction of the body casing; It is configured to be rotatable at least in the longitudinal direction of the grip portion.

When the blower fan 44 is driven after the start of the operation, the suction force that takes the indoor air into the air cleaner A from the air intake port 11 occurs, and the indoor air flows into the air intake port 11.

The air taken in from the air suction port 11 flows backward inside the air cleaner A, and before the filter 13 filters out large dust, the fine dust is filtered by the HEPA filter 12.

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, it is applied to the deodorizing element 62 through the honeycomb-shaped opening. The catalyst adsorbs the odor contained in the air and removes the odor from the air.

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 as the air cleaner A. The clean air inside is blown out.

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. Forming is to make air The flow direction is changed to a curved portion at a position bent upward. A multi-blade fan that is a blower fan 44 is located at the bent portion.

Since the multi-blade fan takes in air from the direction of the rotating shaft of the fan and discharges the taken in air in the radial direction of the fan, a linear flow is generated from the front surface of the main body casing C to the rear, and the airflow can be higher. The wind direction is efficiently changed to face the blower 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.

Thereby, since the flow of the air to the deodorizing element is straight and the air vertically collides with each of the filter faces, the air flow 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 ends 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 is raised to a predetermined temperature and 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 cover 65d which has been coated with the heat radiation rate, and the rear side is covered by the heating unit 63 (the heater unit 63a), the heating is utilized. The heat generated by the unit 63a and the heat radiated from the lid 65d can be efficiently heated by the deodorizing element 62.

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 is the same as the opening angle of the fan-shaped heater unit 63a, or is smaller than the opening angle. can. 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.

Further, the timing of driving the deodorizing element 62 may be performed immediately after the heat treatment, or may be performed immediately before the next air cleaning operation.

Next, referring to Figs. 11 to 12, the deodorizing unit 60 is located in a lower region of the center support body 65b which 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 constituted by the center support body 65b. The sector-shaped region formed by the predetermined opening angle which is enlarged by the left and right 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 increased efficiently, it is possible to The deodorizing element 62 is heated efficiently, 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 . Further, 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 state in which the lattice is removed is shown.

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 the suction port 11 is closed during the heat treatment of the deodorizing element 62, which makes it more difficult to the outside of the air cleaner A. The odor or the like from the deodorizing element 62 generated during the heat treatment is released.

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

As described in the present embodiment, the heating unit 63 can be downsized by changing the relative positional relationship between the deodorizing element 62 and the heating unit 63 that locally heats the deodorizing element 62.

The advantage of the miniaturization of the heating unit 63 is that, for example, it is not necessary to perform a heat treatment for the entire area of the deodorizing element 62, and a large heater such as the entire area of the deodorizing element 62 can be disposed, and the configuration can be simplified or reduced. Cost.

Further, since the relative positional relationship between the deodorizing element 62 and the heating unit 63 can be changed, when the entire region of the deodorizing element 62 is deodorized, the portion where the deodorizing element 62 and the heating unit 63 face each other can be changed, and heating is performed. Unit 63 does not have to cover the entire area of deodorizing element 62.

That is, since the deodorizing element 62 is always opposite to the heating unit 63 The position is a limited portion, so that the hindrance of the heating unit 63 to the flow of the air flowing through the deodorizing element 62 can be minimized. 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, the suction port 11 of the air cleaner A is formed on the front surface of the main body, and the air outlet 42 is formed on either the side surface, the top surface, or the back surface of the main body.

According to this configuration, since the suction opening 11 which is largely open can be easily opposed to the source of the odor, the odor can be absorbed more quickly, and the odor can be removed from the indoor air.

Further, since the suction port 11 is formed on either the side surface, the top surface, or the back surface of the main body, the cleaned air is hard to flow in the source of the odor, and the spread of the odor can be prevented.

Further, the deodorizing element 62 is rotatably supported by the main body casing C, and the heating unit 63 is fixed to the main body casing C so as to be close to the surface of the deodorizing element 62.

Thereby, since the heating unit 63 of the portion where the heater unit 63a generates heat does not move inside the body casing C, it is not necessary to consider the treatment of supplying the wiring for generating the heat source or the portion of the high temperature within the body casing C. A wide range of thermal countermeasures inside the body casing C caused by the change of position.

Further, since the deodorizing element 62 is rotated to change the surface facing the heating unit 63, the entire surface of the deodorizing element 62 can be uniformly opposed to the heating unit 63 by driving the deodorizing element 62 in only one direction. .

Further, since the shape of the deodorizing element 62 is a disk shape, the area of rotation in which the deodorizing element 62 is rotated can be minimized with respect to the area viewed from the direction of the rotation axis of the deodorizing element 62.

That is, the arrangement area of the deodorizing element 62 inside the main body casing C can be made small.

Further, since the deodorizing element 62 changes the surface facing the heating unit 63 by the rotation, the heater unit 63a of the heating unit 63 is the radial direction of the deodorizing element 62 as long as the shape of the deodorizing element 62 is a disk shape. The size is at least the same as, or smaller than, the radius of rotation of the deodorizing element 62, and many regions of the deodorizing element 62 can be heated.

Further, since the shape of the deodorizing element 62 is a disk shape, the circular shape can form a largest area with respect to the opening area of the body casing C which is a rectangular opening, so that the circular shape can be formed. Larger deodorizable area.

Thereby, since more air passes through the deodorizing element 62 and flows, the amount of wind can be increased while maintaining the deodorizing force.

Further, in the deodorizing element 62, a catalyst having a decomposition function of ammonia is applied or immersed on the surface. In this way, it is possible to form a clean air that can quickly deodorize the pet odor or the care odor in a hospital or nursing facility or nursing home. machine.

In particular, in the present embodiment, since the odor can be removed from a larger amount of air in a short period of time, the problem of odor such as care in a place used by many people such as a hospital or a nursing facility can be quickly solved.

Further, since the deodorizing element coats or soaks the surface of the honeycomb core plate with the catalyst for adsorbing ammonia, and performs a coating treatment for preventing the catalyst from peeling off from the surface, the catalyst is not moved or operated. The vibration is peeled off from the honeycomb core.

Therefore, it is not necessary to worry that the inside of the body casing C is contaminated by the catalyst peeled off from the honeycomb core plate.

Further, the blower fan that is the air blowing means is located inside the air passage, the deodorizing element 62 is located on the upstream side of the blower fan 44 in the air passage R, and the heating unit 63 is located between the blower fan 44 and the deodorizing element 62.

Since it is configured in this manner, a space provided for reducing the pressure loss (flow loss of air) generated around the opening 44d of the deodorizing element 62 and the blower fan 44 can be used as the arrangement position of the heating unit 63.

Further, the heating unit 63 includes a casing 63b that is open to the side opposite to the deodorizing element 62 and has a predetermined internal space, and an electric heater unit 63a that is located in the internal space of the casing 63b and radiates heat through the opening; The unit 63a is set to have a heating performance in which the opposing portion of the deodorizing element 62 is raised to a predetermined temperature when the current is applied for a predetermined period of time. Thereby, the odor adsorbed by the deodorizing element 62 can be removed.

Further, the outer casing 63b has a fan shape. Thereby, the area covering the deodorizing element 62 can be made to the minimum required. In addition, the fan-shaped opening angle The degree of rotation is set to be approximately the standard of the angle of rotation when the deodorizing element 62 is rotated.

Further, the control unit 47 incorporates a control program for driving the deodorizing element 62 at a predetermined timing to drive the driving means 64 of the position changing means.

Thereby, when the deodorizing element 62 is heated, the control unit 47 can automatically face the portion of the deodorizing element 62 to be deodorized with the heating unit 63.

Further, the control program has a processing step of driving the driving means 64 at a predetermined timing, stopping the deodorizing element only after rotating the predetermined turning angle, and energizing the heating unit for a predetermined time in the stopped state.

Thereby, the series of operations from the rotation of the deodorizing element 62 to the heating can be automatically performed by the control unit 47.

Further, the air passage R is bent upward on the downstream side of the deodorizing element 62, and the blower fan 44 is disposed in the curved portion, and the blower fan 44 is rotated about the rotation shaft extending in the horizontal direction, and is sent upward. A multi-blade fan that introduces air into the front side of the body casing C.

Since the sirocco fan takes air from the direction of the rotating shaft of the fan and discharges the taken air in the radial direction of the fan, the indoor air can be linearly from the front to the rear of the main body casing C. The flow, and the wind direction can be changed efficiently toward the blow outlet 42.

Further, the heating unit 63 is attached to the main body so as to be located below the center of rotation of the deodorizing element 62.

In this manner, the center of gravity of the air cleaner A can be lowered by arranging the heating unit having a slight weight such as the heater unit 63a at a low position. Thereby, an air cleaner which can be stably disposed on the floor surface can be constructed A.

Further, 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 A of the front outer casing C and the area B of the front side of the suction port is "B". 0.6A".

The relationship is the projected area of the front view of the main body casing C. The suction port of the opening 65a can take the maximum indoor air relationship, and can form a clean air that can take in more indoor air and flow it to the deodorizing element 62. machine.

Further, in order to avoid a state in which the air cleaner A is in a dangerous state when it is overturned during operation, the vibration sensor 47a that detects the fallover is placed on the lower side of the inside of the body together with the control unit 47, so that the vibration is shaken. The width is smaller than the case where it is disposed above the main body casing, and the possibility of detecting weak vibration in parallel is also small.

Further, the dust filter 12 and 13 are attached to the upstream side of the ventilating path R on the deodorizing element 62, and the front panel 10 which is a gas permeable casing is detachably attached to the front surface of the main body casing C, and is attached to The main body casing C is in a state in which the casing is removed, and the filter for filtering dust can be taken out in front of the main casing C. According to this configuration, since the dust filter can be detached from the front side of the main casing C, Improves the maintainability of filters that filter dust that is slightly attached to dust.

Further, the front panel 10 is provided with a recess 28a disposed on the upper portion of the front outer casing 20, a latch 10b provided on the front panel 10, and a latch provided to the front outer casing 20. The latch mechanism constituted by the lock receiving portion 25a is fixed to the front outer casing 20, and since the spring mechanism provided on the front panel 10 of the front outer casing 20 is pressed forward, there is no need to worry about the vibration caused by the movement of the size of the main body. Shake or fall off.

(About the outline of the body casing C)

Next, the outline of the main body casing C will be described with reference to Figs. 15 to 17 .

The air cleaner A 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. Four wheels 90 are provided at the bottom of the front casing 20, two are disposed at the bottom of the rear casing 40, and when the body casing C is viewed from the front side, The center of the main body casing C is symmetrical with respect to each other, and one of the left and right sides is disposed.

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

The handle 91 has a long rod-shaped grip portion 91a in the left-right direction of the main body casing C. The left and right central axes of the grip portion 91a are located at the center of the top surface of the main body casing C, and are provided with the growth side facing the left-right direction.

Further, the position of the handle 91 in the front-rear direction relative to the main body casing C is located in the front casing in such a manner as to be between the heating unit 63 and the blower fan 44. The back side of 20. Moreover, the height L of the grip portion 91a from the floor surface 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.

Furthermore, referring to Fig. 4, a concave portion recessed forward in front of the outer surface of the outer casing 20 before the lower portion of the outer handle 20 is formed. This recess is a portion of the armrest portion 27 of the main body casing C.

The armrest portion 27 is located at the right and left centers of the main body casing C, and is in a positional relationship in which the grip portion 91a of the handle 91 is vertically overlapped. Therefore, the armrest portion 27 is also positioned between the heating unit 63 and the blower fan 44 in the front-rear direction with respect to the main body casing C, like the handle 91.

Further, the upper surface of the rear outer casing 40 is configured to be lower than the upper surface of the front outer casing 20, and the armrest portion 27 is opened by the rear upper portion of the outer casing 20 which is exposed in this manner.

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, the average shoulder width of a Japanese adult is about 426 mm for men, 394 mm for women, and about 409 mm for adults. Don't worry, when you push and pull the air cleaner A from the side, it is located within the shoulder width of the person.

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.

The air cleaner A configured as described above accommodates the power cord as shown below.

Referring to Fig. 20, the upper and lower pair of hooks 50 are disposed on the back surface of the outer casing 40 after being the back surface of the main body casing C. The power supply line K is held in the main body casing C by winding the power supply line K into a pair of hooks 50 disposed above the above-described manner.

Here, if one hook is configured to be close to the other hook, when the power cord of the hook is folded and folded, the one of the hooks is brought close to the other hook, so that the wound power cord can be together. Out of the hook, but can be Expand the power cord quickly.

Further, a configuration in which the power cord is entangled with the hook will be described, but as shown in Fig. 21, the power cord reel may be disposed on the main body.

By configuring the outer body profile as described above, since the wheel is rotatably provided in the main body casing C so as to be rotatable in the longitudinal direction of the grip portion 91a of the handle 91, even the large air cleaner A can be easily pushed and pulled.

In particular, the deodorizing element 62, the heating unit 63, and the like are disposed in the front outer casing 20, and the blower fan 44 or the air outlet 42 is disposed in the rear outer casing, and the handle 91 is formed at the joint portion between the front outer casing and the rear outer casing.

Therefore, the relatively heavy large parts are disposed in a height-balanced manner on the front and rear outer casings, and the handles are formed at the joint portions thereof, whereby the weight balance position can be obtained when the handle 91 is gripped and the air cleaner is pushed and pulled. Move the air cleaner A to the fulcrum.

Further, since the air outlet 42 is disposed in the rear casing, the handle 91 does not interfere with the airflow from the air outlet 42.

Further, the armrest portion 27 is additionally provided in a portion of the main body casing C located below the handle 91.

The height of the handle 91 is set to an average value of the height of the finger of the adult of the Japanese (the vertical distance from the floor surface to the middle finger node in the state where the person stands on the floor surface), and is set so that the user does not have to be greatly bent. The height, but for people who are short, there is a difficult situation. In this case, if the armrest located below the height of the handle is used, it is easy to carry.

Further, in the main body casing C, since the position of the armrest portion 27 is located at a well-balanced position like the handle 91, the air is removed by using the armrest portion 27. In the case of the cleaner A, it is also easy to convey as in the case of using the handle 91.

Further, the upper surface of the rear outer casing 40 is configured to be lower than the upper surface of the front outer casing 20, and the armrest portion 27 is opened by the rear upper portion of the outer casing 20 which is exposed in this manner.

Therefore, since the armrest portion 27 is disposed on the outer surface of the air passage R in the front outer casing 20, the air passage R is not narrowed, and since the armrest portion 27 is not provided to the rear outer casing 40, the air outlet is not caused. The opening area of 42 is narrowed, or the air passage R inside the rear outer casing 40 is narrowed.

In other words, by providing the armrest portion 27 to the main body casing C as described above, the flow region of the air such as the air passage R or the air outlet 42 is not restricted.

Further, since the hook that wraps the power cord is disposed on the back surface of the main body casing C and the power cord is entangled, there is no fear that the power cord will be overturned due to the power cord being moved by the caster.

Moreover, it is easier to use when the power cord reel is placed on the main body instead of the hook that entangles the power cord.
