Description

  The present invention relates to an air purifier capable of purifying air and cleaning of a filter of an air purifier with a humidifying function capable of humidifying while purifying air.

  In general air purifiers and air purifiers with a humidifying function, a combination of a pre-filter that separates coarse dust and dust in the air and a dust collection filter that separates fine dust and fungi as air cleaning means in use. This prefilter removes and protects the dust collection filter in advance so that the dust collection filter does not impair the dust collection effect against fine dust and dirt. Therefore, it is necessary to clean regularly. An automated version of this cleaning work has also been devised.

  For example, an automatic cleaning unit is known in which a cleaning unit that cleans the prefilter reciprocates while sweeping the surface of the prefilter to remove coarse dust and dust (see, for example, Patent Document 1).

  The automatic cleaning means will be described below with reference to FIGS. 9 (a) and 9 (b). FIG. 9A is a schematic front view showing the configuration of a conventional automatic cleaning means, and FIG. 9B is a schematic sectional view showing the configuration of the automatic cleaning means.

  As shown in FIG. 9A, the automatic cleaning means includes a cleaning case 103 having a rotating brush 102 for cleaning the pre-filter 101, a rotating means 104 for rotating the rotating brush 102, and a cleaning case including the rotating means 104. A driving means 105 for reciprocating the 103 up and down is provided.

  Further, as shown in FIG. 9B, the rotating brush 102 includes a shaft member 106 extending in the left-right direction and a fluff portion 107 provided on the surface of the shaft member 106, and the shaft member 106 is a cleaning case 103. It is pivotally supported by the shaft. Further, since the rotating means 104 and the shaft member 106 are connected, the shaft member 106 is rotated by the operation of the rotating means 104. Further, the rotating brush 102 is configured to have such a length that the fluff portion 107 slides on the entire left and right direction of the pre-filter 4 by its rotation.

  Next, the operation will be described.

  When the rotating means 104 is operated, the shaft member 106 rotates, and the fluff 107 provided on the shaft member 106 slides on the surface of the prefilter 4. Rough dust and dust adhering to the pre-filter 4 due to this sliding are scraped from the pre-filter 4 for cleaning. Then, by operating the driving means 20 together with the operation of the rotating means 104, the cleaning case 103 reciprocates up and down the surface of the prefilter 4 to clean the entire prefilter 4.

JP 2008-029912 A

  However, the conventional method has a configuration in which the fluff portion 107 slides on all the left and right surfaces of the prefilter 4 both when moving upward and when moving downward. And the load of the driving means 20 for moving the cleaning case 103 provided with the fluff 107 becomes large. Therefore, the power consumption required for the automatic cleaning operation is increased, and the large and expensive driving means 20 having a large generated torque is required.

  SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, reduces the power consumption required for automatic cleaning operation, and uses an automatic filter cleaning device that can use a small and inexpensive driving means, and an air cleaning device using the same. It is another object of the present invention to provide an air cleaning device with a humidifying function.

  In order to solve the above problems, the problem-solving means in the present invention includes a plurality of cleaning means in which the automatic cleaning means cleans a part of the prefilter, and switching means for sequentially switching the plurality of cleaning means to contact the prefilter. The purpose is achieved by reducing the load on the driving means due to the friction between the prefilter and the brush.

  According to the present invention, the automatic cleaning means has a plurality of cleaning means for cleaning a part of the prefilter, and includes a switching means for sequentially switching the plurality of cleaning means to contact the prefilter. Since the area in contact with the prefilter can be reduced and the friction load can be reduced, the power consumption for automatic cleaning can be reduced, and the effect that a small and inexpensive driving means can be used can be obtained.

  The air purifying apparatus according to the present invention has a configuration in which the automatic cleaning means includes a plurality of cleaning means for cleaning a part of the filter, and includes a switching means for sequentially switching the plurality of cleaning means to contact the filter.

  By adopting such a configuration, the cleaning range of the filter can be shared by a plurality of cleaning means, and the entire surface of the filter can be cleaned by sequentially switching the cleaning means by the switching means. The per-filter contact area can be reduced.

  Therefore, since the frictional force acting between the cleaning means and the filter can be reduced, the driving load on the driving means for driving the cleaning means is reduced, the power consumption for automatic cleaning is reduced, and the torque is small and the size is small. Thus, it is possible to provide an effect that it is possible to provide an air cleaning device that uses inexpensive and inexpensive driving means.

  In addition, the switching unit may automatically switch the cleaning unit automatically by changing the operation direction of the filter cleaning by the automatic cleaning unit. Here, the operation direction of the filter cleaning indicates a direction in which the cleaning unit moves when the filter is cleaned by the operation of the automatic cleaning unit. For example, the vertical direction or the horizontal direction with respect to the filter is shown.

  By adopting such a configuration, other power for operating the switching means can be made unnecessary, so that the configuration of the main body can be simplified.

The first cleaning means and the second cleaning means are provided on the side surfaces of the rotation member, and the first cleaning means and the second cleaning means are at a predetermined angle with respect to the rotation direction of the rotation member. It is good also as a structure arranged. Here, when the pre-filter surface to clean is made into the whole, the remaining part means the remaining part except the part cleaned by the 1st cleaning means from the whole.

  By adopting such a configuration, the rotation member rotates due to the frictional force between the prefilter and the first cleaning means or the second cleaning means due to the change in the operation direction of the automatic cleaning means, and the cleaning that has been in contact with the rotating force has occurred. The other cleaning means, not the means, comes into contact with the prefilter. Therefore, since the cleaning means that comes into contact with the prefilter is automatically changed, there is no need to provide an electric motor or the like as power means for operating the switching means, and the configuration of the main body can be simplified.

  The rotating member may be arranged so as to be detachable from the automatic cleaning means.

  By setting it as such a structure, a user can remove the cleaning member from an automatic cleaning means, and can clean the coarse dust and dust which remained in the cleaning member.

  In addition, the air passes through the main body case having the suction port and the air outlet opened, the air cleaning means having a filter provided in the main body case for removing coarse dust and dust, the air inlet, the air cleaning means, and the air outlet in this order. It is good also as a structure provided with the air cleaning path | route, the ventilation means to ventilate to an air cleaning path | route, and the filter cleaning apparatus in any one of Claims 1-4.

  By adopting such a configuration, it is possible to remove and clean coarse dust and dust from the air in the room, and dust and dust accumulate on the filter due to the use for a predetermined period, and the air cleaning performance deteriorates. In addition, it is possible to provide an air cleaning device that can recover the air cleaning performance by the effect of the filter cleaning device.

  Moreover, it is good also as a structure provided with the humidification means in the air purification path | route of the air purifying apparatus of Claim 5.

  By setting it as such a structure, the air purifier with a humidification function which humidifies with air purification can be provided.

As shown in FIG. 2, an air cleaning means 5 having a pre-filter 4 for removing coarse dust and dust is erected inside the main body case 1, and the above-described suction port 2, air cleaning means 5, and air outlet 3 are provided. The air purification path 6 through which air can pass in this order is formed.

  The air cleaning means 5 is provided with a prefilter 4 on the upstream side of the air cleaning path 6, and on the upstream side of the prefilter 4, as shown in FIG. 3, coarse dust and dust adhering to the prefilter 4. An automatic cleaning means 7 for automatically cleaning is provided. Returning to FIG. 2, the air blowing means 8 that forms the air cleaning path 6 is disposed on the rear side of the air cleaning means 5, and external air is taken into the body case 1 and passes through the air cleaning means 5. And can be discharged from the outlet 3 to the outside of the main body case 1.

  By adopting the above configuration, the air taken into the main body case 1 by the air blowing means 8 is filtered and purified by the air cleaning means 5, and the cleaned air is discharged from the air outlet 3 to the outside of the main body case 1. Can do. Thereby, the air of object space can be cleaned. Then, when a predetermined operation time has passed and the pre-filter 4 is closed due to adhesion of coarse dust and dust, and the air volume blown by the blowing means 8 is reduced, the control for operating the automatic cleaning means 7 is performed. Operate. Since the automatic cleaning means 7 removes coarse dust and dust from the pre-filter 4, the air volume blown by the air blowing means 8 is restored.

  The air cleaning means 5 includes, for example, a substantially flat plate prefilter 4 formed by knitting resin fibers in a lattice shape, and a substantially rectangular parallelepiped dust collection filter 9 formed by bending a filter medium into a bellows shape. And a deodorizing filter 10 in which an adsorbent such as activated carbon is attached to a resin net.

The order in which the air taken into the main body case 1 passes through the dust collection filter 9 and the deodorizing filter 10 may be any.

  As the air blowing means 8, for example, a sirocco fan, a turbo fan, a propeller fan, or a cross flow fan that is rotationally driven by an electric motor driven by a direct current or an alternating current is raised. A sirocco fan can take high static pressure even at a low speed, a turbo fan has higher fan efficiency than a others, a propeller fan can take a large air volume even at a low speed, and a cross-flow fan produces a blown airflow. Since the width can be increased, an optimal method may be selected depending on the case.

  Next, the configuration of the automatic cleaning means 7 will be described with reference to FIGS. 4 and 5. FIG. 4 is a schematic perspective view showing the configuration of the rotating member, and FIG. 5 is a schematic perspective view showing the configuration of the cleaning arm.

  As shown in FIG. 4, the first cleaning means 11 for cleaning a part of the pre-filter 4 and the second cleaning means 12 for cleaning the remaining part of the pre-filter 4 are provided in the rotating member 13, and as shown in FIG. The rotating member 13 is rotatably supported by the rotating member frame 14. Returning to FIG. 4, the rotating member 13 is formed in a substantially bowl shape, and the first cleaning means 11 and the second cleaning means 12 are provided on the side surface in the longitudinal direction. The shape of the rotating member 13 may be a substantially cylindrical shape or a substantially semi-cylindrical shape.

  The lengths of the first cleaning means 11 and the second cleaning means 12 (referring to the length in the same direction as the longitudinal direction of the rotating member) are the first cleaning means indicated by the arrow 15 in FIG. 11 and the length of the second cleaning means 12 indicated by the arrow 16 are arranged at predetermined lengths such that the sum of the length of the second cleaning means 12 indicated by the arrow 16 is equal to or greater than the length of the rotating member 13 indicated by the arrow 17. ing. However, the lengths of the first cleaning means 11 and the second cleaning means 12 are arranged to be shorter than the length in the longitudinal direction of the rotating member 13.

  Here, as the first cleaning means 11 and the second cleaning means 12, for example, a multi-brush brush member molded from a resin material or a metal material, a sponge member formed by porous molding of a resin material, or a rubber member molded into a plate shape Etc.

  As shown in FIG. 5, the rotating member frame 14 is detachably disposed with respect to a cleaning arm 18 that moves on the surface of the prefilter 4 in the vertical direction.

  Although the cleaning arm 18 returns to FIG. 3, when the automatic cleaning operation is not in operation, the cleaning arm 18 is stationary at a stationary position 19 provided above the prefilter 4 of the main body case 1 (broken line portion). A driving means 20 constituted by an electric motor or a combination gear is disposed in the main body case 1, and the cleaning arm 18 can be moved in the vertical direction of the pre-filter 4.

  In addition, a dust box 21 as a storage means for storing the coarse dust and dust removed from the prefilter 4 is detachably provided at the lower part of the main body case 1.

  Next, the configuration of the switching unit 22 that switches the cleaning unit that contacts the pre-filter 4 by rotating the rotating member 13 between the first cleaning unit 11 and the second cleaning unit 12 will be described with reference to FIG. To do. FIG. 6 is a side sectional view showing the configuration of the rotating member 13.

  The switching means 22 includes a first cleaning means 11 and a second cleaning means 12 arranged at a predetermined angle with respect to the rotation direction of the rotating member 13 indicated by an arrow 23 in FIG. A plurality of protrusions 24 are formed as stoppers that define the rotation angle of the rotating member 13 by contacting the rotating member frame 14.

  The first cleaning means 11 and the second cleaning means 12 are such that when the cleaning arm 18 moves in the forward path, the first cleaning means 11 contacts the prefilter 4 and when the cleaning arm 18 moves in the backward path, the second cleaning means 12 4 is arranged at an angle contacting 4. The angle shown here is an angle formed by the first cleaning unit 11 and the second cleaning unit 12 around the rotation axis of the rotating member 13.

  Hereinafter, the operation will be described with reference to FIGS. 3, 7A and 7B. FIG. 7A is a schematic cross-sectional view showing the operation of the rotating member 13 when the moving direction of the cleaning arm 18 is changed from below to above, and FIG. 7B is the direction of movement of the cleaning arm 18 from above to below. It is a schematic sectional drawing which shows operation | movement of the rotating member 13 at the time of a change.

  When the automatic cleaning operation starts, as shown in FIG. 3, the cleaning arm 18 starts to move downward from the stationary position 19 by the action of the driving means 20, and the first cleaning provided in the rotating member 13 included in the cleaning arm 18. The means 11 moves from the upper end to the lower end of the pre-filter 4 while sliding a part of the pre-filter 4, and removes the coarse dust and dust adhering to the surface of the pre-filter 4 from the pre-filter 4. The coarse dust and dust removed from the prefilter 4 fall into a dust box 21 provided below the main body and stored. Then, when the first cleaning means 11 reaches the lower end of the pre-filter 4, the traveling direction of the cleaning arm 18 is reversed by the action of the driving means 20, and starts to move upward. A path from the stationary position 19 to the lower end of the pre-filter 4 is defined as a forward path.

  At this time, as shown in FIG. 7A, the rotating member 13 pivotally supported on the rotating member frame 14 of the cleaning arm 18 has a frictional force between the first cleaning means 11 and the prefilter 4. Rotate in the direction indicated by arrow 25. And the protrusion part 24 as a stopper formed in the rotation member 13 contacts the rotation member frame 14, and the rotation member 13 does not rotate any more. At this time, since the first cleaning means 11 and the second cleaning means 12 are arranged at a predetermined angle, the rotation of the rotating member 13 is performed at a position where the second cleaning means 12 is just in contact with the prefilter 4. It will stop.

  When the cleaning arm 18 starts to move upward, the second cleaning means 12 that is in contact with the prefilter 4 slides on the remaining portion of the prefilter 4, that is, the portion that the first cleaning means 11 is not cleaning. It moves from the lower side of the pre-filter 4 to the upper side, reaches the stationary position 19 while removing the coarse dust and dust adhering to the surface of the pre-filter 4 and stops still. A path from the lower end of the prefilter 4 to the stationary position 19 is defined as a return path. The coarse dust and dust removed from the prefilter 4 fall into the dust box 21 and are stored.

  When the air cleaning operation for a predetermined time elapses, the automatic cleaning means starts operating again, and the cleaning arm 18 starts to move downward. At this time, as shown in FIG. 7B, the rotating member 13 rotates in the direction indicated by the arrow 26 by the frictional force acting between the second cleaning means 12 and the pre-filter 4. And the protrusion part 24 as a stopper formed in the rotation member 13 contacts the rotation member frame 14, and the rotation member 13 does not rotate any more. At this time, since the first cleaning means 11 and the second cleaning means 12 are arranged at a predetermined angle, the rotation of the rotating member 13 stops at the position where the first cleaning means 11 just contacts the prefilter 4. become. In the same manner as described above, the cleaning arm 18 moves from the upper side to the lower side of the prefilter 4 so that the prefilter 4 can be cleaned.

  Here, when the pre-filter 4 is cleaned from the upper side to the lower side by the automatic cleaning means, the conventional brush rotates as the cleaning means rotates and slides on the surface of the pre-filter 4 to cause coarse dust and dust. Was to be removed. The rotating brush 102 moves while cleaning the entire surface of the prefilter 4 from above to below. Therefore, since the entire surface of the pre-filter 4 is cleaned at a time, the contact area between the rotary brush 102 and the pre-filter 4 is large, and the frictional resistance applied to the rotary brush 102 increases. The driving load applied to the driving means 105 to be moved was large.

  As described above, the present invention assigns the area to be cleaned of the prefilter 4 to the first cleaning means 11 and the second cleaning means 12, that is, a part of the prefilter 4 in the forward path (the right half in FIG. 3). The remaining part of the pre-filter 4 on the return path, that is, the portion not cleaned on the forward path (the left half in FIG. 3) is cleaned, so that the area where the cleaning means and the pre-filter 4 come into contact can be reduced. . Therefore, since the frictional resistance with the pre-filter 4 per cleaning means is less than that of the conventional method, the load on the driving means 20 for moving the cleaning arm 18 can be reduced.

  Therefore, power consumption for automatic cleaning can be reduced, and a small and inexpensive driving means with a small torque can be used.

  The automatic cleaning means 7 has a switching means for switching between the first cleaning means 11 for cleaning on the forward path and the second cleaning means 12 for cleaning on the return path. As described above, the switching means is an operation for cleaning the prefilter 4. A structure that can be automatically and sequentially switched with a change in direction, that is, when the traveling direction of the cleaning arm 18 is switched, the rotating member 13 is rotated by friction between the first cleaning means 11 and the second cleaning means 12 and the prefilter 4. Since the switching action is performed, no other power unit is required for switching the cleaning unit, and the configuration of the main body can be simplified.

  With the above-described configuration and operational effects, the air purifying apparatus according to Embodiment 1 of the present invention can achieve the intended purpose.

  In this embodiment, the case where there are two cleaning units has been described. However, three or more cleaning units may be provided, and a plurality of cleaning units are sequentially switched by the switching unit as described above. The same effect can be obtained.
