The present invention relates to an air cleaner for passing indoor air sucked into a body by a borrowing device through a deodorizing portion, thereby removing odor components in the air and deodorizing the indoor air.

In the past, there is an air cleaner comprising: a body casing; an air suction port formed in a front surface of the body casing; an air blowing outlet formed on an upper rear portion of the body casing; and a fan disposed in the body casing, And used to draw air from the air intake port and then blow out to the air outlet; the fan motor is used to drive the fan; and the dust collecting filter is disposed on the upstream side of the fan to trap dust in the inhaled air. In the vicinity of the air blowing port, the deodorizing portion is formed by attaching a catalyst to the surface of the adsorbing material for adsorbing the odor component, and the heating portion is for restoring the deodorizing function of the deodorizing portion. And heating.

The air purifier drives the fan to take indoor air into the body casing from the air suction port, and then removes the dust by the dust collecting filter, and then adsorbs to the deodorizing portion by the adsorbing material of the deodorizing portion. The odor component in the indoor air is deodorized in the indoor air.

It is necessary to operate the air cleaner 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.

Therefore, the portion close to the adsorbent of the heater is odor-removing because it can be heated at a high rate, but the portion of the adsorbent material away from the heater may not be efficiently conducted from the heat of the heater, but has an undetermined The possibility of completely removing the odor.

Therefore, in such a configuration, since the performance of adsorbing the odor of the adsorbent cannot be sufficiently restored, the deodorizing function of the air cleaner may be lowered.

The present invention has been made in order to solve the problems as described above, and an object of the invention is to provide an air cleaner which can efficiently reduce the odor of indoor air and which can efficiently and efficiently absorb the odor-absorbing material. restore.

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 open to the outside, and that has ventilation for connecting the suction port to the air outlet; Built into the body, and the indoor air is introduced 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 deodorized by heating by the heating means. restore.

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 casing 40 is attached to the rear of the front casing 20 with the opening 41 facing forward. 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.

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, an air cleaner constructed as shown above In the inside of A, a ventilation path R is taken in which indoor air is taken in, and the air is cleaned and deodorized, and then released into the room. 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 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 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 change the wind direction toward the air outlet 42 with high efficiency.

Further, the deodorizing element 62, the front filter 13, the HEPA filter 12, The front surface of the opening 44d of the blower fan 44 is 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 heating unit 63a to cause the heating unit 63a to generate heat. On the other hand, the portion facing the deodorizing element 62 with respect to the heating 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 63d which has been coated with the heat radiation rate, and the rear side is covered by the heating unit 63 (heating unit 63a), Heating single unit The heat generated by 63a and the heat radiated from the lid 63d can be heated efficiently by the deodorizing element 62.

Further, since the deodorizing element 62 is located at a position sandwiched by the heating unit 63a and the lid 63d, heat radiated from these members is easily accumulated in the vicinity of the deodorizing element 62, and can be higher for the deodorizing element 62. Heat efficiently.

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 63d 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. 63d clipped position.

Further, the angle at which the deodorizing element 62 is rotated may be the same as the opening angle of the fan-shaped heating 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 heating 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.

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 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.

Next, 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 side of 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.

Next, the deodorizing element 62 is supported to be rotatable in the body casing C, and the heating unit 63 is fixed to the body casing C so as to be close to the surface of the deodorizing element 62.

By this means, since the heating unit 63 that heats the portion of the unit cell 63a is not moved inside the body casing C, it is not necessary to consider the treatment of supplying the wiring for generating the heat source or the high temperature portion to be changed inside the body casing C. A wide range of thermal countermeasures within the body casing C caused by the 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. .

Next, since the shape of the deodorizing element 62 is a disk shape, the area of rotation in which the deodorizing element 62 is rotated 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 shape of the deodorizing element 62 is a disk shape, because A plurality of regions of the deodorizing member 62 can be heated in such a manner that the radial direction of the heating unit 63a of the heating unit 63 is at least the same as or smaller than the radius of rotation of the deodorizing element 62.

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.

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 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.

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 heating unit 63a is located in the inner space of the outer casing 63b and radiates heat through the opening; the heating unit 63a is set to a heating performance in which the opposing portion of the deodorizing element 62 is raised to a predetermined temperature when energized 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 opening angle of the sector is configured such that the rotation angle of one rotation of the deodorizing element 62 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 dust are disposed on the upstream side of the deodorizing element 62, and the front panel 10 having the gas permeable body is detachably attached to the main body casing C. In the front, in a state in which the frame is removed from the main body casing C, the filter for filtering dust can be taken out in front of the main 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, it is possible to increase the filtration of the slightly larger dust. The maintainability of the dust filter.

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 cocoa, efficiently changes the wind direction to change the wind direction efficiently toward the blower 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 heating 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 and the area B of the front view of the suction port is "B≧". 0.6A".
