Further, since the driving means 64 is provided at a position away from the heating unit 63, it is possible to make the driving portion 64 less susceptible to the heat generated by the heating unit 63.

Next, the front panel 10, the front outer casing 20, the rear outer casing 40, and the deodorizing portion 60, which constitute the respective portions as described above, are assembled together with other functional components as described below to constitute the air cleaner A.

First, the rear outer casing 40 is such that the opening 41 faces forward and is installed in front. The rear of the outer casing 20. At this time, the opening 44d of the blower fan 44 provided in the rear outer casing 40 is in a positional relationship with respect to the rear opening 24 formed in the partition plate 23 provided in the front outer casing 20. Further, the center of the opening of the rear opening 24 and the axis of the rotating shaft of the blower fan 44 are aligned in the front and rear.

Next, the deodorizing unit 60 inserts the frame 61 from the front opening 22 of the front outer casing 20 into the front outer casing 20, and holds the outer periphery of the casing 61 inside the front outer casing 20, thereby being attached to the front outer casing 20.

In the state in which the deodorizing unit 60 is attached to the front outer casing 20 in this manner, the rear side of the deodorizing unit 60 (the side on which the heating unit 63 is mounted) is disposed toward the rear opening 24 of the front outer casing 20, and the heating unit 63 is located. Between the deodorizing element 62 and the rear opening 24.

Here, the deodorizing element 62 and the bell mouth are formed around the opening 44d of the blower fan 44, and the partition 23 of the outer casing 20 and the rear opening 24 are formed so as not to hinder the flow of air from the deodorizing element 62 to the rear opening 24. And opposite each other across a predetermined interval D.

In this manner, since the distance between the portion of the air blower fan 44 that takes in the air and the pressure loss of the air flowing from the deodorizing element 62 is ensured, the bias of the wind speed distribution at the deodorizing element 62 is more averaged, and the deodorizing element is suppressed. The pressure loss caused by 62 can ensure the efficiency of the intake air of the blower fan 44 and can suppress the deterioration of the aerodynamic performance.

Further, the interval D is about 40 mm to 60 mm.

Further, the heating unit 63 is located at a portion of the interval D formed in this manner.

Next, a HEPA filter 12 having a size similar to that of the opening of the frame 61 is provided inside the frame 61 attached to the deodorizing portion 60 of the front outer casing 20, The front filter 13 is disposed in such a manner as to cover the front surface of the HEPA filter 12.

Further, the air cleaner A is configured by providing the front panel 10 on the front side of the front filter 13 so as to be sandwiched by the upper projection portion 28 and the lower projection portion 25 of the front outer casing 20.

Further, the HEPA filter 12 is a filter for filtering fine dust such as pollen contained in the air, feces of the ticks, fungi of molds, dust of houses, and the like.

Further, the front filter 13 is a filter for removing the large dust of the large dust contained in the air before the air is filtered by the HEPA filter, in order to maintain the effect of the HEPA filter for a long period of time.

Next, referring to Fig. 4, in the air cleaner A configured as described above, a ventilation passage R that takes in indoor air and discharges the air and deodorizes the air, and then discharges the air into the room is formed. The air passage R is described along the flow of the air taken in from the inside to explain the air clean operation state of the air cleaner A.

First, the user operates the operation unit 26 and inputs it to the control unit 47, thereby executing a predetermined program for performing the operation of the air cleaner A.

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 is formed from the surface to the back A plurality of openings in the shape of a honeycomb, and a catalyst that adsorbs odor is applied 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 from the air. Remove odor.

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. 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.

Since 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, a linear flow is generated from the front surface of the main body casing C to the rear, and the efficiency is more efficient. The wind direction is changed to face 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 the air to the deodorizing element is straight and the air vertically collides with each of the filter faces, the air flow is excellent.

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 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.

As described above, the control unit 47 is used to control the respective units using a control program including the processing steps shown below.

First, the light from the light-emitting portion 71 to the light-receiving portion 72 is angled by the angle plate 62d. In the state of being blocked (the state in which the reproduction step of the last deodorizing element is completed), the driving means 64 is driven to turn the deodorizing element 62 in a predetermined direction.

Next, when the control unit 47 detects the angle plate 62d that rotates together with the deodorizing element 62 and blocks the light from the light-emitting portion 71 to the light-receiving portion 72, the control unit 47 stops the driving means 64, and the deodorizing element 62 stops rotating.

That is, by performing the rotational driving of the deodorizing element 62, the light is blocked from the angle plate 62d located beside the turning opposite side of the deodorizing element 62 of the angle plate that blocks the light toward the light receiving portion 72 in the initial state. The light from the portion 71 to the light receiving portion 72 is in a stopped state after the deodorizing element 62 is rotated only by a predetermined angle.

Next, the control unit 47 energizes the heating unit 63 for a predetermined period of time while the deodorizing element 62 is stopped, thereby heating the portion facing the deodorizing element 62 and the heating unit 63, and restoring the deodorizing of the deodorizing element 62. performance.

Further, the control program may include a driving means for operating the position changing means of the deodorizing element for a predetermined period of time, and if the light from the light emitting portion is not blocked by the angle plate, the operation of the driving means is stopped and the predetermined operation is performed. The processing steps for the error display.

According to the above, 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 63d are sandwiched, and the new portion of the deodorizing element 62 that adsorbs a lot of odor is located at the heated unit 63 and the lid body 63d. Clamp the position and restore the deodorizing performance by heating.

Further, the angle of the opening angle θ at which the deodorizing element 62 is rotated may be the same as the opening angle of the heating portion 63f of the fan-shaped heater unit 63a or may be smaller than the opening angle. That is, adjacent angle plates and deodorizing elements The angle of the center of the member 62 may be the same as the opening angle of the heating portion 63f of the fan-shaped heater unit 63a, or may be 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 heating portion 63f, 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.

By forming the respective portions of the air cleaner A as described above, the following effects 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 portion where the deodorizing element 62 always faces the heating unit 63 is a limited portion, the interference of the heating unit 63 with the flow of the air flowing through the deodorizing element 62 can be minimized. Thereby, more air can be flowed to the deodorizing element 62, and more air can be removed from the air at one time. Stinky.

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.

In particular, the deodorizing element 62 is formed into a disk shape such that the center of the deodorizing element 62 coincides with the center of the air cleaner body in the left-right direction, since the deodorizing element 62 is disposed to rotate relative to the body, thereby maximizing By utilizing the dimensions of the body in the left-right direction, the deodorizing area of the larger deodorizing element can be ensured.

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

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, the photo sensor 70 composed of the light-emitting portion 71 and the light-receiving portion 72 is provided in a central support that is a fixed side inside the air cleaner, and the deodorizing element that is rotated by the driving means is separated by a predetermined interval. The angle plate 62d that blocks the light from the light-emitting portion 71 to the light-receiving portion 72 is arranged in a ring shape on the basis of the center of the deodorizing element. Therefore, the control unit detects whether or not the light of the light-receiving portion 72 is detected. The angle of rotation of the odorous element 62.

Thereby, since the rotation of the deodorizing element 62 can be controlled in accordance with the size of the heating unit 63 opposed to the deodorizing element 62, it is possible to appropriately respond to the timing of the heat treatment for recovering the deodorizing force of the deodorizing element 62. The heating unit 63 is opposed to the area of the deodorizing element 62 to be heat treated.

In particular, if the arrangement interval of the angle plate based on the center of the deodorizing element is set to be the same as or smaller than the opening angle of the heating plate, since the rotation of the deodorizing element can be controlled to be the same as the opening angle of the heating plate or The rotation angle is smaller than this, so that the heating plate can be evenly opposed to the deodorizing element. Thereby, the entire surface of the deodorizing element can be continuously subjected to heat treatment.

Further, the control program used by the control unit 47 first drives the light from the light-emitting portion 71 to the light-receiving portion 72 by the angle plate 62d to drive the light. The means 64 drives the deodorizing element 62 to a predetermined direction. Next, when the control unit 47 detects that the angle plate 62d that rotates together with the deodorizing element 62 blocks the light from the light emitting unit 71 to the light receiving unit 72, the control unit 47 stops the driving means 64 and stops the deodorizing element 62. Turn.

That is, by performing the rotational driving of the deodorizing element 62, the angle plate 62d located beside the turning reverse side of the deodorizing element 62 that blocks the angle plate of the light toward the light receiving portion 72 in the initial state blocks the light emitting portion. 71 light to the light receiving portion 72. Thereby, the deodorizing element 62 is in a stopped state only after being rotated by a predetermined angle.

Next, the control unit 47 energizes the heating unit 63 for a predetermined period of time while the deodorizing element 62 is stopped, thereby heating the portion facing the deodorizing element 62 and the heating unit 63, and restoring the deodorizing of the deodorizing element 62. performance.

Since the heating control of the deodorizing element 62 is performed in this manner, the portion to be heat-treated by the deodorizing element 62 can be appropriately opposed to the heating unit 63, and heated without being exposed to a portion where the heat treatment is not performed. deal with.

Further, the control program may include a case where the driving means 64 for changing the position of the deodorizing element 62 is operated for a predetermined period of time, and if the light from the light-emitting portion 71 is not blocked by the angle plate, the operation of the driving means 64 is stopped. And perform the processing steps for the given error display.

By using such a control program, the control unit 47 can recognize that the deodorizing element 62 does not operate even if the position changing means is operated, so that appropriate measures such as erroneous display or stop of operation can be performed.

Secondly, since the shape of the deodorizing element 62 is a circular plate shape, it can be made The area of rotation in which the deodorizing element 62 rotates becomes the smallest as 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.

Therefore, since more air flows through the deodorizing element 62 and flows, the amount of wind can be made large while maintaining the deodorizing force.

Next, in the deodorizing element 62, a catalyst having a decomposition function of ammonia is applied or immersed on the surface. Thereby, it is possible to constitute an air cleaner which can quickly deodorize the pet odor or the care odor at a hospital or a nursing facility or a nursing home.

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.

Next, the air blowing fan that is the air blowing means is located inside the air passage, and the deodorizing element 62 is located on the upstream side of the air blowing fan 44 in the air passage R, and the heating sheet The element 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.

Next, 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 inside 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. Further, the fan-shaped opening angle is configured such that the one-time rotation angle when the deodorizing element 62 is rotated is substantially standard.

Next, the control unit 47 incorporates a control program for driving the deodorizing element 62 by the driving means 64 which is a position changing means at a predetermined timing.

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.

Next, in the ventilation path R, the filters 12 and 13 for filtering the dust are provided. It is placed on the upstream side of the deodorizing element 62, and the front panel 10 having the gas permeable body is detachably attached to the front surface of the main body casing C. The state in which the casing is detached from the main body casing C can be A filter for filtering dust is taken out from the front of the main body casing C.

According to this configuration, since the filter for filtering dust can be detached from the front side of the main body casing C, the maintainability of the filter which is easy to adsorb dust of slightly larger dust can be improved.

Then, 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.

Next, 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, the air cleaner A which can be stably provided in the floor surface can be comprised.

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 in the front view and the area B of the front view of the suction port becomes "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.

Next, the air cleaner A constructed as described above is movable as shown in Figs. 15 to 17 .

As described in detail below, the air cleaner A of the present embodiment is constituted by various functional components such as the outer casing C and the deodorizing portion 60 provided in the 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, 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 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, and 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.

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.

Therefore, the air cleaner A can be used even in a narrow passage or place. Easy to move.

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.
