Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an air conditioner having a function of automatically removing dust attached to a filter. More specifically, the removed dust can be stored for a long time, and can be easily collected. Related to air conditioners.
[0002]
[Prior art]
The air outlet of the air conditioner (indoor unit) is provided with a filter for removing dust in the air. The dust accumulates on the filter in proportion to the operation time of the air conditioner. If the amount of dust increases, the heat exchange efficiency decreases, so it is necessary to clean the filter appropriately.
[0003]
Generally, the filter is manually removed from the indoor unit housing by removing the dust from the indoor unit housing by a customer's hand, for example, and then removing the dust by hand washing.
[0004]
However, since a normal air conditioner is installed at a high place in a room, it is difficult for an elderly person or a woman to attach / detach a filter, so that there is a problem that a cleaning operation is easily avoided.
[0005]
Therefore, for example, an air conditioner with a cleaning device for automatically cleaning a filter as disclosed in Japanese Utility Model Laid-Open No. 4-33916 (Prior Art 1) and Japanese Utility Model Laid-Open No. 4-50320 (Prior Art 2) has been proposed. .
[0006]
However, the prior art 1 employs a method of rubbing off dust adhering on the filter while moving the brush in the horizontal direction along the flat filter, so that the application is limited to the flat filter. In particular, a filter of a recent air conditioner is accommodated by bending or bending the filter surface in accordance with the downsizing of the housing, and thus cannot be dealt with by the prior art 1.
[0007]
In the prior art 2, the filter is pulled out of the air conditioner by a rotating roller, and dust is attached to the filter from a suction cylinder and a suction pipe previously installed on the upper part of the outdoor unit, and the filter is removed again. In this method, the suction cylinder and the suction pipe must be separately provided outside the housing, and the design as an indoor unit is lacking.
[0008]
Further, in the method of storing dust removed from the filter, for example, as shown in JP-A-3-122422 (prior art 3), a filter is stretched between take-up cylindrical rollers. Then, there is a method of removing dust attached to the filter together with the operation of winding up the filter.
[0009]
However, in the case of the prior art 3, since the dust attached to the filter is wound up together with the filter and stored in the filter storage section, the filter is disposable and must be wound in a large amount, resulting in an increase in cost. The result was a burden on the customer. In addition, the filter housings must be provided on both sides of the housing, and the size of the entire indoor unit is increased, which is a problem against miniaturization.
[0010]

[0044]
At the time of cleaning the filter 6, it is desired that the cleaning state of the filter is not exposed to the eyes of the customer. Therefore, when the filter 6 is moved toward the second filter storage space S2 by the filter moving means 6, it is preferable that the upper and lower wind direction plates 251 provided in the air blowing section 25 be closed. In this embodiment, the filter cleaning is performed when the operation of the air conditioner 1 is stopped, and the upper and lower wind direction plates 251 are in a closed state.
[0045]
Next, the configuration inside the housing 2 will be described. In the housing 2, a heat exchanger 3, a blower 4, a dust removing section 5, and a filter 6 are arranged at predetermined positions.
[0046]
As shown in FIG. 1, the heat exchanger 3 includes a front-side heat exchanger 31 in which two heat exchanger units are vertically connected and a rear-side heat exchanger 32 including one heat exchanger unit. The front-side heat exchanger 31 and the rear-side heat exchanger 32 are fixed to the base 21 via left and right side plates 33 and 34.
[0047]
The blower 4 is composed of a cross flow fan arranged on the upstream side of the air passage 24, and is supported between the left and right side plates of the base 21, similarly to the heat exchanger 3. By driving the blower 4, air is sucked in from the air suction portions 221 formed on the front surface and the upper surface of the panel 22, the dust is removed through the filter 6, and the temperature is adjusted to a predetermined temperature in the heat exchanger 3. The air is blown from the air blowing unit 25 toward the room.
[0048]
In the vicinity of the top of the heat exchanger 3, a dust removing section 5 is arranged. As shown in FIG. 1, the dust removing unit 5 includes a box 51 for collecting dust attached to the filter 6, and a filter moving unit 56 that slides the filter 6 reciprocally is provided adjacent to the box 51. Is provided.
[0049]
The box body 51 has a top cover 511 disposed above the filter 6 and an under cover 512 disposed below the filter 6. As shown in FIG. The cover 512 is formed longer than at least the width of the filter 6.
[0050]
Both the top cover 511 and the under cover 512 are formed of a synthetic resin molded product. In a more preferred embodiment, the synthetic resin preferably contains a fungicide, an antibacterial material, or the like. According to this, generation of mold and the like can be suppressed, and a clean state can be maintained.
[0051]
Opening grooves 513 and 514 as filter insertion portions are opened at least wider than the width of the filter 6 between the facing surfaces of the top cover 511 and the under cover 512.
[0052]
The edges of the opening grooves 513 and 514 are each bent inward, and a pair of upper and lower scrapers 54 and 55 for preventing dust attached to the filter 6 from being taken out of the box body 51 are formed. ing. In this embodiment, the scrapers 54 and 55 are fixed tongue pieces, but may be movable pieces that open and close when sliding, for example.
[0053]
In this embodiment, the undercover 512 has a U-shaped cross section formed in a mortar shape downward (toward the heat exchanger 3), and has a bottom portion on which collected dust is transferred to the dust storage portion 582. Is provided.
[0054]
Brushes 52 and 53 project from the top cover 511 and the under cover 512 toward the filter 6, respectively. In the first embodiment, the brush 52 provided on the top cover 511 is formed of an inclined brush with bristles planted obliquely with respect to the filter surface, and the brush 53 provided on the undercover 512 is a brush 53. The hair consists of a straight brush implanted in a direction perpendicular to the filter surface.
[0055]
According to this, since the brush 52 is inserted along the mesh of the filter 6, an effect of scraping dust attached to the filter 6 is generated, and dust can be more reliably removed.
[0056]
The bristles of each of the brushes 52 and 53 are mainly made of synthetic resin such as nylon. However, similarly to the case of the above-described box body 51, a fungicide or an antibacterial material may be added and / or applied. May be added and / or applied.
[0057]
Further, a pressing means such as a compression spring may be provided on the bottom side of each of the brushes 52 and 53, so that each of the brushes 52 and 53 may be constantly pressed toward the filter 6. Waste dust can be more reliably captured.
[0058]
As shown in FIGS. 2 and 3, the dust feeding means 58 is composed of a screw conveyor having substantially the same length as the under cover 512, and has a rotating motor 581 for rotating the screw conveyor at one end (the left end in FIG. 2). Is provided. On the other end side (the right end in FIG. 2), a dust storage portion 582 for storing dust sent by the dust sending means 58 is provided.
[0059]
In this first embodiment, a screw conveyor system is adopted as the dust feeding means 58. As another means, as shown in FIG. 4, a belt conveyor type dust feeding means 58 is provided at the bottom of the under cover 512. The dust sending means 58 can be appropriately selected as long as dust can be reliably sent.
[0060]
The dust storage portion 582 is stored between one of the side plates (the side plate 34 in FIG. 2) of the heat exchanger 3 and the side surface 222 of the panel 22. Usually, a certain amount of extra space is provided on the side surface of the heat exchanger 3 for the purpose of protecting the cooling pipe. Therefore, by arranging the garbage storage unit 582 here, the space in the indoor unit housing 2 can be more effectively used. In addition to being usable, the volume of the dust storage section 582 can be increased.
[0061]
In this embodiment, the rotary motor 581 and the dust storage unit 582 are separately provided on the left and right sides of the screw conveyor, but may be installed at the same position on one end of the screw conveyor.
[0062]
The filter feeding means 56 is composed of a motor controlled by a control unit (not shown), and its rotating shaft 561 is provided with a driving wheel 562 for contacting the filter surface of the filter 6 and feeding the filter 6 in a predetermined direction. .
[0063]
The drive wheel 562 is made of, for example, a high friction material such as rubber. In this embodiment, the drive wheel 562 has an uneven surface on its surface to increase the gripping force on the filter 6 surface. A driven roller 57 that is paired with the drive wheel 562 is provided at a position opposite to the drive wheel 562 across the filter 6.
[0064]
As shown in FIG. 2, the rotating shaft 561 is provided with two pairs of driving wheels 562 and driven rollers 57 for each filter 6.
[0065]
Next, as shown in FIG. 5, the filter 6 is formed by integrally forming a filter surface in a lattice-like frame. In this case, the filter surface is composed of a filter surface 63 on the front end Fa and a filter end 63 on the rear end Fb. And an opening 65 through which dust on the upper surface is dropped onto the dust sending means 58 along the width direction between the filter faces 63 and 64.
[0066]
In this embodiment, the filter 6 is made of, for example, a base resin such as polypropylene, and it is more preferable to further add an antistatic material such as a conductive resin to the base resin. That is, since the filter 6 is easily charged by friction with the nylon brushes 52 and 53, the dust is prevented from being attracted by the charging. In addition, a fungicide or an antibacterial material may be further added.
[0067]
Next, an example of a procedure for cleaning the filter 6 of the air conditioner 1 according to the first embodiment will be described. First, when a filter cleaning button provided on a remote controller or the like is operated, a control unit (not shown) issues a drive command to the motor 56 to rotate the motor 56 in a direction in which the filter 6 moves in the forward direction.
[0068]
For example, with the forward rotation of the motor 56, the filter 6 starts moving in the forward direction (left direction in FIG. 1). As the filter 6 moves while passing between the brushes 52 and 53 in the box 51, dust attached to the filter 6 is wiped off. Further, as the filter 6 moves in the forward direction, the front end Fa of the filter 6 passes through the second filter guide groove 62 and the second filter housing between the upper and lower wind direction plates 251 and the left and right wind direction plates 252 of the air blowing unit 25. It is led to the space S2.
[0069]
At this time, the upper and lower wind direction plates 251 of the air blowing unit 25 are in the “closed” state, and the cleaning can be performed without exposing the filter 6 in the rotating state to the outside.
[0070]
After confirming the predetermined moving amount (for L2) in the forward direction, the control unit issues a reverse rotation command to the motor 56 to rotate the motor 56 in the reverse direction in which the filter 6 moves in the backward direction. The filter 6 sent in the backward direction is again cleaned between the upper and lower brushes 52 and 53 in the box body 51, and the rear end Fb of the filter 6 passes through the first filter guide groove 61 and is removed from the base 21. It is led to the first filter storage space S2 on the back side. The amount of movement of the filter 6 in the backward direction corresponds to the sum of the amount of movement L2 in the forward direction and the length of L1.
[0071]
At this time, a large amount of scraped dust is deposited on the upper surface side of the filter 6. However, when the opening 67 provided in the filter 6 is located immediately below the box 51, The accumulated dust falls through the opening 67 to the bottom (bottom cover 512) side of the box body 51.
[0072]
At the same time as the movement of the filter 6 is controlled, the control unit drives the dust feeding means 58 to send the dust accumulated at the bottom of the bottom cover 512 to the dust storage unit 582 provided on the side surface by the screw conveyor.
[0073]
Finally, the control unit rotates the motor 56 in the forward direction again to move the filter 6 to the initial position, and a series of filter cleaning operations ends.
[0074]
Thereby, the filter can be cleaned inside the housing 2 without pulling the filter 6 out of the housing 2. The removed dust is stored in the dust storage unit and can be stored for a long period of time. In the first embodiment, the filter cleaning has been described for one reciprocation in the forward direction and the backward direction. However, the order of movement may be reversed, and the number of reciprocations and the speed may be appropriately selected.
[0075]
Next, an air conditioner according to a second embodiment of the present invention will be described with reference to FIGS. The air conditioner 1 according to the second embodiment has the same basic configuration and functions as those of the air conditioner according to the first embodiment, and common parts are denoted by the same reference numerals, and description thereof is omitted. I do.
[0076]
The feature of the second embodiment is the position of the dust removal unit 5 for cleaning the filter 6. That is, in the second embodiment, the dust removal unit 5 is provided on the back side of the housing 2, that is, on the top of the base 21.
[0077]
Along with the arrangement of the dust removing section 5, a filter storage space S3 capable of receiving the filter 6 over substantially the entire length is secured on the base 21 side.
[0078]
The box body 51 constituting the dust removing portion 5 is formed of a combination of a top cover 511 and a bottom cover 512. In the second embodiment, one end of the top cover 511 and the bottom cover 512 (in FIG. The end side) is open to the filter storage space S3 on the back of the base 21.
[0079]
According to this, the dust scraped off in the box body 51 falls from the rear end side of the box body 51 toward the bottom of the base 21, and falls between the ventilation guide surface 212 of the base 21 and the partition plate 27. It is deposited in the formed space.
[0080]
In this embodiment, a connection port 214 to which a negative pressure suction means such as a vacuum cleaner can be connected is provided at the bottom of the filter storage space S3.
[0081]
As shown in FIG. 6, the connection port 214 is formed of a cover member that can be opened and closed at the bottom of the base 21. The connection port 214 is opened, and the suction pile 9 such as a vacuum cleaner is inserted into the connection port 214. The dust accumulated on the bottom can be easily removed. Such an embodiment is also included in the present invention.
[0082]
FIG. 7 shows a modification of the dust removing section 5. In this modified example, the dust removal section 5 is also used as the filter storage space S3. In the filter storage portion S3, the brushed fibers 54 which have been charged in advance are arranged so as to come into contact with the filter 6.
[0083]
In this modified example, the raised fibers 54 are formed by sticking a sheet-like material in which a large number of raised fibers 54 are planted on a base sheet along the filter storage space S3. The fibers may be directly implanted and formed. A brush other than the raised fibers 54 may be used, and any brush can be appropriately selected as long as it can capture dust.
[0084]
According to this, dust adhering to the filter 6 can be captured in the capturing space together with the slide of the filter 6, and the configuration can be simplified and inexpensive.
[0085]
If the connection port 214 is provided below the base 21, the connection port 214 may be opened and dust may collectively drop at the same time. Therefore, a tongue piece such as a rubber piece is provided at the opening of the connection port 214. It may be temporarily closed to prevent dust from falling.
[0086]
In each of the embodiments described above, the filter cleaning is performed when the operation is stopped. However, the filter cleaning may be performed during the operation depending on the control method. Further, the rotation operation of the filter is not limited to one reciprocation, but may be performed a plurality of times.
[0087]
