- the fan 54 for blowing the air heat-exchanged in the room 52 into the room and the filter device 56 arranged on the upstream side of the heat exchanger 52 are accommodated, and formed from the front surface to the upper surface of the main body 50.
- air is sucked by the operation of the plurality of suction loci fans 54, and dust floating in the air is removed by a filter device 56 provided between the suction port and the heat exchanger 52.
- FIG. 2 is an overall configuration diagram of the filter device 56 of the air conditioner that is effective in the present invention.
- the filter device 56 that removes dust from the air passing through the heat exchanger 52 includes a filter frame 2, a filter network 4 held in the filter frame 2, and a filter network 4. It is equipped with a suction nozzle 6 that can slide along the surface.
- the suction nozzle 6 can be smoothly moved to the left and right with a certain distance from the filter network 4 by a pair of guide rails 8 installed at the upper and lower ends of the filter frame 2.
- One end of the suction duct 10 is connected to the suction nozzle 6 and the other end of the suction duct 10 is connected to the suction device 12.
- the suction duct 10 is formed of a duct that can be bent so as not to interfere with the movement of the suction nozzle 6.
- an exhaust duct 14 is connected to the suction device 12 and is routed outside the room. Dust adhering to the filter net 4 is sucked from the suction nozzle 6 and further discharged to the outside through the suction duct 10, the suction device 12, and the exhaust duct 14.
- the suction nozzle 6 uses a suction position switching device for cleaning the entire surface of the filter network 4 by increasing the suction force by narrowing the suction to a part and switching the position.
- FIG. 3A and 3B show the structure of the suction nozzle 6 according to Embodiment 1 of the present invention.
- the suction nozzle body 16 has a long, slit-like opening 1 corresponding to the entire length of the filter network 4. 8 and a suction hole 22 is provided in the belt 20 that can be driven along the opening 18.
- suction can be performed from only a part of the opening 18, and the place of suction by driving the belt 20 can be changed.
- the belt 20 follows the suction nozzle body 16, it is guided by a belt guide 24 formed integrally with the suction nozzle body 16 by welding, bonding, etc. Suppression leakage is prevented from occurring in parts other than 22. With such a configuration, even a small amount of air is squeezed by the small suction hole 22, the air speed of the air passing through the suction hole 22 is increased, and a strong suction force can be exhibited even with a small suction device.
- a sheet brush 26 using a thin sheet is provided on the surface of the benolet 20 as a dust separating member that separates dust adhering to the filter net 4 from the filter net 4. It is fixed to the side, and the position of the sheet brush 26 as well as the suction hole 22 can be changed by driving the belt 20. With this configuration, only the driving device for the belt 20 is required for changing the suction position and the seat brush position, so the configuration is simple and can be realized at low cost. The positional relationship of the brush 26 can always be maintained.
- the entire surface of the filter network 4 is cleaned by driving the belt 20 of the suction nozzle 6 to change the positions of the suction holes 22 and the brush 26, so that the suction nozzle 6 is connected to the filter network 4 as shown in FIG.
- the suction hole 22 and the brush 26 are reciprocated as shown by the arrows in the figure by driving left and right along.
- the suction hole 22 and the brush 26 are set to approximately 1/4 of the total length of the filter network, and the entire surface of the filter network 4 is cleaned by four reciprocating sweep operations as indicated by arrows in the figure.
- the height hi of the sheet brush 26 shown in FIG. 3B is designed by the distance from the filter network 4.
- the distance between the filter net 4 and the suction nozzle 6 is designed to be 1.5 mm at the axial center of the suction nozzle 6 so that the filter net 4 does not come into contact even if there is a deflection (maximum lmm). . Therefore, when the deflection of the filter network 4 occurs in the opposite direction to the suction nozzle 6, the suction nozzle 6 and the filter network 4 are separated by a maximum of 2.5 mm. In this state, hi is set to 5. Omm so that the sheet brush 26 can sufficiently contact the filter network 4.
- the sheet brush 26 has an L-shaped sheet, and the fixing area is increased by increasing the area of the portion that is bonded to the belt 20. If this shape is used, the portion bent into the L-shape can easily fall down to the belt 20 side, and is supported by the belt guide 24 to maintain the L-shape.
- the L shape is used to increase the bonding area, so it may be an inverted T shape or other similar shapes.
- the seat brush 26 also has a bent state depending on the driving position of the belt 20, but the sheet is very thin and the bent portion is deformed into a wave shape and can be driven without any problem.
- the bent portion of the sheet brush is not illustrated in a wavy shape. Since the benolet 20 and the sheet brush 26 are required to have flexibility in bending as well as durability against tensile strength and wear, it is preferable to use rubber or a resin film.
- resin films such as PET (polyethylene 'terephthalate) and PEN (polyethylene' naphthalate) are excellent in strength, flexibility, and durability. Due to their mechanical strength, Benoleto 20 is 75 to 100 microns. Since it can be made as thin as possible, the suction nozzle 6 itself can also be made thin to improve storage. As a result, it is possible to reduce the thickness of the indoor unit main body, which is preferable in terms of design. In terms of cost, material costs and processing costs are extremely low.
- the sheet brush 26 has a thickness of about 0.5 to 1. Omm when rubber is used because of material properties, and about 50 to 75 microns when a resin film is used.
- FIG. 5 is an enlarged view of a part of the seat brush 26 (B portion in FIG. 3A), and shows the state before and after the bonding process.
- the seat brush 26 is very simple. Can be fixed to the belt 20.
- welding thermal welding or ultrasonic welding
- extremely strong fixing can be performed as compared with fixing with an adhesive.
- FIG. 6A and FIG. 6B are structural views of a suction nozzle using a bristle brush.
- a bristle brush 28 is fixed to the surface of the belt 20 next to the suction hole 33. This bristle brush 28 is the finale Since the dust adhered to the filter net 4 is peeled off, the dust that cannot be removed from the filter net 4 by the suction force alone can be sucked and cleaned. A brushed cloth is often used for the bristle brush 28.
- the position of the bristle brush 28 is changed along with the suction hole 22 by the driving of the belt 20, and the dust brush peeled off by the bristle brush 28 is sucked from the suction hole 22 by being always present beside the suction hole 22.
- FIG. 7 is a schematic cross-sectional view of the suction nozzle when the suction nozzle 6 using the bristle brush 28 is cleaned.
- the solid arrows indicate the wind of suction, and the white arrows indicate the direction of travel when the suction nozzle 6 moves forward.
- the bristle brush 28 is attached to the rear of the suction hole with respect to the cleaning progress direction of the forward movement of the suction nozzle 6.
- the white circles indicate dust that is easily sucked, such as dry dust, and the black circles indicate dust that is strongly attracted to the filter net 4 due to oil or cigarette dust.
- the seat brush 26 used in the suction nozzle 6 solves the problems inherent to the bristle brush 28 described above, and realizes the suction nozzle 6 in which dust entanglement does not occur. .
- FIG. 8 is a schematic sectional view of the suction nozzle at the time of cleaning in the present embodiment, and shows the state of the suction nozzle 6 and the filter network 4 in the middle of cleaning the filter network 4 in a cross section. Is. The arrows and circles in FIG. 8 are the same as those in FIG. FIG. 8 shows a portion having the suction hole 22 in FIG. 3A, that is, the state of the AA cross section. Since the suction hole 22 precedes the seat brush 26, dry dust and the like are peeled off from the filter net 4 by suction force and removed by suction.
- the dust that has been peeled off is cleaned by being sucked into the suction holes 22 located nearby.
- By cleaning the surface of the filter net 4 so as to stroke the filter net 4 is cleaned while the hair is swollen, and the resistance is much smaller than that of the combed brush, and the suction nozzle 6 is driven left and right.
- the motor to be used is small in output and small in size, and is also advantageous in terms of reliability, such as the temperature rise of the motor.
- the fact that a small motor can be used has the advantage of increasing the degree of freedom in terms of the design of the indoor unit body. Since the seat brush 26 is flexible, even if the filter net 4 is deformed or bent, the sheet brush 26 is deformed accordingly and the tip of the seat brush 26 is in close contact with the filter net 4 without any gaps, so that dust is drawn. The ability to peel off is high and the cleaning performance is very good. On the other hand, due to its flexibility, dust is not pushed out to the opposite side (heat exchanger side) of the filter network 4. The force at which the dust that has been forcibly pulled off by the seat brush 26 may accumulate at the tip of the seat brush 26 is also sucked and removed when it accumulates to some extent.
- the seat brush 26 has no part where dust is entangled, and the surface is smooth, making it difficult to attach dust. Even if it adheres to the surface, it will come off as soon as it is rubbed with the filter net 4. Therefore, by using the seat brush 26, the cleaning performance can be maintained permanently, and maintenance such as cleaning of the brush is unnecessary.
- FIGS. 9A and 9B show the structure of the suction nozzle of the filter device 56 according to the second embodiment of the present invention, which is the same as that of the first embodiment described above in that a plurality of cuts are provided in the seat brush 26A. Is different.
- Fig. 9A and Fig. 9B the cut is made up to the tip force root of the seat brush 26A (surface on the side of Benoleto 20), and the shape is cut as if it was cut into a V shape. So that there is a gap.
- Fig. 10 is an enlarged view of a part of the seat brush 26A (E portion in Fig. 9A), showing the state before and after the bonding process, as shown in Fig. 10. The distance between the edges of the cuts is 2 mm, and the tip of each cut is applied with a V-shape so that the dimension of the end is 1 mm.
- the filter mesh 4 uses 40 meshes (40 filter fibers per inch).
- the distance between the fibers in the filter mesh 4 is 0.64 mm, and if the tip of the seat brush 26A is set to 0.64 mm or more, it will enter the mesh of the filter mesh 4 and get caught.
- the margin is also set to lmm. Especially the dimensions of the tip) It is preferable to design it larger than the mesh spacing of the mesh 4. If the mesh of the filter mesh 4 is fine, the force that can reduce the gap between the cuts of the sheet brush 26A is applied to the sheet brush 26A, for example, a resin film with a thickness of 75 to 100 microns. When is used, it is not preferable to make it too fine from the viewpoint of tensile strength.
- the seat brush 26A has a role of removing dust from the filter network 4. This action of peeling off dust is effective even when the sheet brush 26A is stroking the filter net 4. Further, when the seat brush 26A tries to return to its original shape by elastic force, it can be used to repel dust. Strong peeling ability can be obtained.
- FIG. 11A and FIG. 11B are schematic views showing the effect.
- FIG. 11A shows that the seat brush 26A is dragged by the filter network 4 during the cleaning, and the suction nozzle 6 moves in the direction of travel. The state is greatly deformed backward. The amount of deformation increases when large dust or dust that is strongly stuck to the filter net 4 comes into contact with the seat brush 26A. Even if dust starts to collect at the tip of the seat brush 26A, it becomes larger. When the amount of deformation exceeds a certain value, the seat brush 26A that was originally perpendicular to the surface of the belt 20 tries to return to the original (perpendicular) state by the elastic force.
- FIG. 11B shows such a state, and the dust is repelled to the suction hole side and sucked and removed by the momentum at this time.
- the power at this time is strong, so it is large, so it can be repelled by dust, dust, and dust. You can do it.
- the sheet brush 26A is provided with a plurality of cuts, the fine sheet pieces formed by the cut frequently perform this operation, so that the ability to remove dust is greatly improved as compared with the case where no cuts are made. In addition, this effect is particularly noticeable when using PET or PEN, or using a resin film with physical properties.
- the provision of a plurality of cuts in the seat brush 26A increases the flexibility of the entire seat brush. As a result, even if the filter network 4 is bent or uneven, the sheet brush 26A comes into contact with the filter according to the shape and can be cleaned to every corner.
- FIG. 12 is a simplified cross-sectional view of the suction nozzle in the present embodiment, and shows only the suction nozzle body 16, the belt 20, the suction hole 22, and the seat brush 26 A in FIG. 9A.
- the belt 20 is driven to change the position of the suction hole 22 in order to clean the entire surface of the filter net 4.
- the sheet brush 26A is provided with a plurality of fine cuts, and when passing through the bent portion of the suction nozzle 6, the sheets subdivided by the cut overlap to form a bent portion.
- it does not need to be deformed in a wave shape. Therefore, since an excessive force is not applied to the seat brush 26A, deterioration does not occur, and durability and reliability are improved.
- the cut in a V-shape the area where the seat brush 26A overlaps can be reduced as shown in Fig. 12. Therefore, the deterioration of the seat brush 26A is also reduced, which is preferable.
- the cut is inserted in a V-shaped manner up to the tip force root (surface on the belt 20 side) of the seat brush 26A so that a gap is formed.
- this is useful for attracting dust on the opposite side of the seat brush 26A to the suction hole 22.
- the seat brush 26 obstructs the wind sucked from the suction hole 22, and no suction force acts on the dust on the opposite side of the seat brush 26 with respect to the suction hole 22.
- the filter net 4 is vertical and there is dust that has passed over the seat brush 26 due to the force, the suction force does not work, so it falls and soils the indoor unit body.
- a plurality of cuts are made in the seat brush 26A and a gap is formed in each, the suction wind passes through the gap, so the seat brush 26A Dust that has passed over can be sucked and cleaned.
- FIG. 13 is a schematic diagram of the suction nozzle 6 during cleaning according to the present embodiment.
- the white arrow in the figure indicates the wind of suction, and the magnitude indicates the strength of the wind. From Fig. 13, it can be seen that the wind escapes through the gap on the opposite side of the seat brush 26A. In addition, it can be seen from FIG. 13 that the width of the cut line of the sheet brush 26A is made larger than the width of the mesh of the filter net 4 so that it is not caught by the mesh of the filter net 4.
- the seat brush 26A is reciprocated by the suction nozzle 6. Touches the entire surface of the filter network 4. Also in this case, since the suction air passes through the gap, dust on the opposite side of the seat brush 26A can also be sucked and cleaned.
- the two seat brushes 26A are arranged on one side of the suction hole 22.
- the two seat brushes 26A are attached to the suction holes 22. It may be arranged on both sides.
- the air sucked into the suction hole 22 is guided by the two sheet brushes 26A, and the two sheet brushes 26A also have an effect of preventing the diffusion of the sucked air.
- the suction air speed increases and the cleaning performance improves.
- 16A and 16B show the structure of the suction nozzle of the filter device 56 according to the third embodiment of the present invention.
- a foamed silicon brush 30 obtained by foaming silicon like a sponge is used as a belt. This is different from the first embodiment described above in that it is fixed to 20.
- the foamed silicon brush 30 is designed so that the width d2 is 5 mm and the height h2 is 5 mm.
- the width is determined in consideration of the cleaning performance and driving resistance, and also varies depending on the silicon material.
- the height of the filter network 4 and the suction nozzle 5 is designed so that it can be sufficiently contacted even at a maximum distance of 2.5 mm. However, in the case of foamed material, it is pressed against the filter network 4 and slightly compressed to become a steady state.
- FIG. 17 is a schematic cross-sectional view of the suction nozzle during cleaning in the present embodiment, and shows the state of the suction nozzle 6 and the filter network 4 in the middle of cleaning the filter network 4 in section.
- the solid line arrow in the figure indicates the wind of suction
- the white arrow indicates the direction of travel during the forward movement of the suction nozzle 6.
- the circles on the filter net 4 indicate adhering dust (dust removed by the filter net 4).
- White circles indicate dust that is easily sucked, such as dry dust
- black circles indicate dust that is difficult to be sucked in because it contains a small amount of oil
- black triangles indicate dust that is very hard to be sucked in because it contains a large amount of oil.
- the foamed silicon brush 30 is attached to the rear of the suction hole 22 with respect to the cleaning progress direction of the forward movement of the suction nozzle 6.
- FIG. 17 shows a portion having a suction hole in FIG. 16A, that is, the state of the FF cross section.
- the suction hole 22 precedes the foamed silicon brush 30, so that dry dust (white circles) and the like are removed from the filter net 4 by suction and removed by suction. Dust that is hard to be sucked in (black circles) that cannot be removed only by suction force due to oil or the like adheres to the surface of the filter network 4 while the foamed silicon brush 30 that is deformed after passing through the suction holes 22 flexibly deforms. Draw the dust off the filter net 4 while stroking the surface of the net 4. The dust that has been peeled off is cleaned by being sucked into the suction hole 22 located nearby.
- the pills that come out are easily peeled off from the filter net 4 by being rubbed with foaming material, and the pills are also in a state where the surface area increases and is easily sucked. .
- This behavior is sometimes seen when a bristle brush is used, but when foam is used as a brush, there is a tendency to become smaller pills. It won't clog.
- FIG. 18A and FIG. 18B most of the dust is sucked and removed by cleaning the forward movement of the suction nozzle 6, and the remaining dust balls that are difficult to be sucked are cleaned by the cleaning operation. It can be removed by suction, and high cleaning performance can be demonstrated against any dust.
- the pill after the forward movement is small, so it does not fall and is held by the filter net 4 and cleaned during the return operation.
- a material such as EPT ethylene propylene rubber
- silicon is used because it does not adhere to the surface even with oil-containing dust and has excellent durability against wear. Is most preferred.
- foamed materials silicon is superior in strength and can prevent damage due to friction with the filter network 4 during cleaning.
- the foam material traps dust so that it wraps around, it does not push out dust to the opposite side (heat exchanger side) of the filter network 4 like a bristle brush.
- the foam material is soft, there is almost no sound that rubs against the filter net 4 during cleaning, and noise reduction during cleaning can be achieved.
- the foamed silicon brush 30 is obtained by quadrupling the foaming rate, which has the best cleaning performance, based on an experiment for comparatively evaluating cleaning performance.
- FIGS. 20A and 20B show the structure of the suction nozzle of the filter device 56 according to the fourth exemplary embodiment of the present invention, and a sponge having a trapezoidal cross section next to the suction hole 22 is formed on the surface of the belt 20.
- a brush 32 made of a foam material such as EPT (ethylene propylene rubber) is fixed, and the position of the brush 32 together with the suction hole 22 can be changed by driving the belt 20.
- the width W of the brush 32 on the side in contact with the filter network 4 is the cleaning performance and resistance during driving.
- the height H of the brush 32 takes into account the amount of deflection of the filter network 4, and the brush 32 and the filter network 4 can be in sufficient contact with each other and are slightly compressed. The height is set so that
- the cross-sectional shape of the brush 32 in the left-right direction is not limited to a trapezoidal shape as long as it can satisfy the shape in which the length on the belt side is longer than the length on the filter net side.
- other similar shapes such as a cross-sectional shape combining a trapezoid and a rectangle, may be used.
- FIG. 21 is a schematic cross-sectional view of the suction nozzle during cleaning in the present embodiment, and shows the state of the suction nozzle 6 and the filter net 4 in the cross-section when the filter net 4 is being suction-cleaned. It is.
- the arrows, circles, etc. in the figure are the same as those in the above-described third embodiment (particularly, FIG. 17), and the description thereof is omitted.
- the operation and action of the suction nozzle 6 are the same as those in the third embodiment.
- the surface 32a on the side in contact with the filter net 4 is uneven, and the left and right drive side surfaces 32b and 32c are By smoothing, it is possible to improve especially the dust discharge property from the filter network 4 and the durability against repeated bending of the brush 32.
- FIG. 23 shows the structure of the suction nozzle of the filter device 56 according to the fifth embodiment of the present invention. Since the basic structure of the suction nozzle 6 itself is the same as that of Embodiment 4, the description thereof is omitted.
- the brush 34 is composed of a foam material 36 and a sheet material 38 provided on the side surface on the left and right drive sides.
- the foam material 36 can be reinforced, the bending durability can be improved, and the occurrence of cracks can be prevented.
- the contact resistance between the brush 34 and the filter network 4 can be reduced, and an increase in driving torque can be suppressed, and the brush 34 can be easily deformed. It is maintained and can improve the durability against repeated bending of the brush 34 in the left-right drive direction.
- the above-described seat brushes, foamed silicon brushes, and the like according to the first to fifth embodiments adopt a suction cleaning method, and other filter devices (for example, a type of cleaner that only dusts off).
- the filter device is also useful, and is not limited to the filter device described in the first to fifth embodiments.
- the filter device of the air conditioner according to the present invention can clean the entire filter network by using the suction nozzle and the combined suction and brush, so that various shapes can be used. It can be used for air filters and air filters used under various installation conditions. Therefore, it can be applied not only to the air filter of an air conditioner but also to an air filter such as a device having a cooling fan (for example, an air filter of a stabilized power supply), a filter device that automatically cleans an air filter such as a ventilation fan.
- a cooling fan for example, an air filter of a stabilized power supply
