- the air filter that removes dust from the air passing through the heat exchanger 4 is composed of a filter frame 10 and a filter network 12 held by the filter frame 10, along the surface of the air filter.
- a slidable suction nozzle 14 is attached.
- the suction nozzle 14 can be smoothly moved to the left and right with a certain distance from the air filter by a pair of guide rails 16 installed at the upper and lower ends of the filter frame 10.
- One end of a suction duct 18 is connected to the suction nozzle 14, and the other end of the suction duct 18 is connected to a suction device 20.
- the suction duct 18 is formed of a duct that can be bent so as not to interfere with the movement of the suction nozzle 14. Further, an exhaust duct 22 is connected to the suction device 20 and is routed outside the room. Dust adhering to the air filter is sucked by the suction nozzle 14 and discharged to the outside through the suction duct 18, the suction device 20, and the exhaust duct 22.
- the suction nozzle 14 is set to clean the entire filter surface by switching the suction position of the suction nozzle 14 by increasing the suction force by narrowing the suction to a part.
- the suction nozzle body 24 corresponds to the entire length of the air filter.
- a long slit-like opening 26 is formed.By providing a suction hole 30 in the belt 28 that can be driven along the opening 26, suction can be performed only from a part of the opening 26, and the belt 28 is It is set so that the place to be sucked can be changed by driving. Further, since the belt 28 needs to be slid along the suction nozzle body 24, the belt 28 is guided by a belt guide 32 formed integrally with the suction nozzle body 24 by welding, adhesion, or the like, and other than the suction holes. Suppressing the occurrence of leaks at the part.

- the dust adhering to the air filter is usually dry, so that the filter device having the above-described configuration can be sufficiently cleaned.
- the air filter is cleaned by removing the dust adhering to the air filter only by the force of the wind that is sucked and sucking it out, so the cleaning performance may not be sufficient.
- the dust attached to the air filter contains a large amount of oil, and the dust adheres firmly to the air filter due to adhesion and hardening of the oil. It may not be possible to clean and remove alone.
- FIG. 5 shows an example of a suction nozzle equipped with a brush, and the brush is attached over substantially the entire length of the suction nozzle body.
- this method since there is a brush in a portion other than the sucked portion, there is a possibility that dust is swept away by the brush and dropped.
- the air filter of a general household air conditioner has a vertical part, in the suction nozzle configuration in which the brush also peels off the dust that has not been sucked, the indoor unit The body may be soiled.
- the suction nozzle according to Embodiment 1 of the present invention can be cleaned without dropping dust even in the vertical portion of the air filter, and the details will be described below.
- 6A and 6B show the suction nozzle of the filter device of the air conditioner according to the first embodiment of the present invention.
- the suction nozzle body 24 is provided with a long slit-like opening 26 corresponding to the entire length of the air filter, and a belt 28 that can be driven along the opening 26.
- the suction hole 30 is provided in the suction hole 30 so that suction is performed only from a part of the opening 26, and the belt 28 is driven to change the suction location.
- the belt 28 runs along the suction nozzle body 24, the belt 28 is guided by the belt guide 32 formed integrally with the suction arch I nozzle body 24 by welding, bonding, etc. Suction leakage is prevented from occurring in the part.
- a brush 34 as a dust separating member for separating dust adhering to the filter net 12 from the filter net 12 is fixed to the side of the suction hole 30 on the surface of the belt 28, and is sucked by driving the belt 28.
- the position of the brush 3 4 can be changed along with the hole 30.
- the drive device required for changing the suction position and the brush position is only the drive device for the belt 28, so the configuration is simple and can be realized at low cost.
- the position of the brush 34 can always be maintained.
- the brush 34 is attached to the rear of the suction hole with respect to the direction of the cleaning of the suction nozzle 14. This is for the air filter of an air conditioner installed in a general household. As an elephant! /, If there is a large amount of dust, such as an air conditioner air filter installed at a restaurant, etc. Sometimes it is better. The reason for this will be described later.
- the length of the brush 34 may be the same as the length of the suction hole 30, but the brush 34 may be shorter than the suction hole 30 in order to reliably suck dust near the upper and lower ends of the brush 34.
- the suction hole 30 may be shorter than the brush 34.
- the length of the suction hole 30 and the length of the brush 34 are designed in consideration of the strength of the suction force and the amount of dust to be removed.
- a brush such as a brushed cloth is often used as the brush 34, but the brush 34 is not limited to a bristle brush as long as it has an effect of removing dust on the air filter.
- FIG. 7A and 7B are schematic cross-sectional views of the suction nozzle 14 at the time of suction cleaning in Embodiment 1 of the present invention, and show the state of the suction nozzle 14 and the air filter while the air filter is sucked I cleaned. Show.
- the solid arrows in the figure indicate the wind of suction, the circles on the air filter indicate the dust adhering to the air filter (the dust removed by the air filter), and the white circles are sucked in such as dry dust. Black circles mean dust that is hard to be sucked in because it contains some oil.
- the white arrow indicates the direction of cleaning of the suction nozzle 14.
- the brush 34 is attached to the rear of the suction hole with respect to the direction of cleaning of the suction nozzle 14.
- FIG. 7A shows the portion with the suction hole in FIG. 6A, that is, the state of the BB cross section. Since the suction hole 30 precedes the brush 34, dry dust and the like are peeled off from the air filter by suction force and removed by suction. Dust that cannot be removed only by suction force due to oil or the like is also removed from the air filter by the brush 34 that comes after passing through the suction hole 30. Since there is a suction hole 30 on the end face of the brush 34 close to the force at which the dust forcibly removed by the brush 34 is collected, it is removed by suction when it accumulates to some extent. Therefore, even if this part is a vertical part of the air filter, dust does not fall. On the other hand, FIG.
- the belt 28 of the suction nozzle 14 is driven to change the positions of the suction hole 30 and the brush 34, and the suction nozzle 14 is driven left and right along the air filter. Clean the entire air filter with a sweeping operation that repeats the reciprocating motion as shown by the arrows in the figure.
- the cleaning method shown in Fig. 8 the dust in the air filter is removed during the forward movement, and the cleaned part is simply returned during the backward movement. Rather, the cleaning performance is improved by cleaning the dust left after the forward operation again during the backward operation, and the dust entangled with the brush 34 is peeled off from the brush 34 during the backward operation and sucked out. Therefore, it becomes possible to suppress the entanglement of dust on the brush 34, and as a result, the cleaning performance is improved.
- the suction position is switched by the drivable belt 28 provided with the suction hole 30, and the brush 34 is provided beside the suction hole 30 on the belt 28 to provide the suction hole 30.
- the brush 34 comes into contact with the air filter only in the vicinity of the position, and the dust removed by the brush 34 is immediately sucked. Therefore, it is possible to prevent the dust from falling even in a portion where the air filter is vertical, and it is possible to exhibit high cleaning performance using the brush 34 and suction together.
- FIGS. 9A and 9B are schematic cross-sectional views of the suction nozzle 14 when cleaning dust that is very difficult to be sucked.
- a brush 34 is provided behind the suction hole 30 described in FIGS. 7A and 7B. If cleaning is performed with a suction nozzle 14 of a different type, dust will move inside the brush 34 as shown in Figure 9A. It moves into the air filter surface and rubs on the surface of the air filter. In the figure, black triangles indicate dust that is very difficult to be sucked in because it contains a large amount of oil.
- the pills that come out are easily peeled off from the air filter by being rubbed by the brush 34, and the surface area is increased by becoming a pill, and the force is also in a state of being easily sucked. Since the hole 30 is in front of the brush 34, it is not sucked during the forward movement and is sucked during the backward movement. In this case, there is a risk that the suction hole 30 will be clogged with the sucked hairball because the hairball that has grown to some extent during the forward movement will grow into a larger hairball during the backward movement. Accordingly, in such a case, as shown in FIG. 9B, the brush 34 is attached in front of the suction hole 30 with respect to the cleaning progress direction of the suction nozzle 14, and the hairball grows more when sucked during the forward movement. It is good to be able to suppress.
- FIGS. 10A and 10B show the structure of the suction nozzle of the filter device of the air conditioner according to Embodiment 2 of the present invention.
- the overall configuration of the filter device is the same as that of Embodiment 1 of the present invention.
- the suction nozzle body 24A is provided with a long slit-like opening 26 corresponding to the entire length of the air filter, and the suction hole is formed in the belt 28A that can be driven along the opening 26.
- suction can be performed from only a part of the opening 26, and the suction location is changed by driving the belt 28A.
- the belt 28A follows the suction nozzle body 24A, it is guided by the belt guide 32A formed integrally with the suction nozzle body 24A by welding, adhesion, etc., and suction leakage occurs at portions other than the suction hole 30 Is suppressed.
- Two openings 26 and two suction holes 30 are provided in parallel, so that suction is performed at two locations.
- a brush 34 is fixed between the two suction arch I holes 30.
- the brush 34 is interlocked with the suction position switching mechanism.
- the brush 34 can be driven.
- the brush 34 is used as an auxiliary means for cleaning. "Dust that is easily sucked”, “Dust that is hard to be sucked”, “Dust that is very hard to be sucked"
- FIG. 11A and FIG. 11B show the state of the suction nozzle and the air filter in a sectional view while the air filter is being cleaned according to the present embodiment.
- the arrows, circles, etc. in the figure indicate the same as described above, and various dusts are present in a mixed state.
- FIG. 11A shows the portion having the suction hole 30 in FIG. 10A, that is, the state of the DD cross section. Dry dust and the like are sucked out by the suction hole 30 in front of the brush 34 and removed by suction from the air filter.
- Dust that is difficult to be sucked in by a small amount of oil or the like is peeled off from the air filter by the brush 34 that has passed through the suction hole 30, and the suction hole 30 in front of the brush 34 is sucked and removed. Dust that contains a large amount of oil and is difficult to be sucked in enters the inside of the brush 34 and is rubbed on the air filter surface to be collected in a hairball shape, and the dustball that has come out on the opposite side of the brush 34 is removed.
- the suction hole 30 behind the brush 34 is removed by suction. In this way, it is possible to cope with various kinds of dust suction cleaning.
- FIG. 11B shows the portion without the suction hole in FIG. 10A, that is, the state of the EE cross section. Since there is no suction hole 30, there is no suction force, but at the same time, there is no brush 34. The dust on the air filter is not affected at all, and even if this part is the vertical part of the air filter, the dust does not fall.
- the suction nozzle is provided with the suction holes 30 on both sides of the brush 34, thereby preventing dust from falling at the vertical portion of the air filter. Sufficient cleaning performance corresponding to various dusts can be obtained.
- FIGS. 12A and 12B show the configuration of the suction nozzle of the filter device of the air conditioner according to Embodiment 3 of the present invention.
- the overall configuration of the filter device is the same as that of Embodiment 1 of the present invention.
- the suction nozzle body 24B is provided with a long slit-shaped opening 26 corresponding to the entire length of the air filter, and the suction hole is formed in the belt 28B that can be driven along the opening 26.
- the belt 28B is guided by the belt guide 32B formed integrally with the suction nozzle body 24B to suppress the occurrence of suction leakage at portions other than the suction hole 30.
- a brush 34B is fixed to the surface of the belt 28B so as to surround the suction hole 30. By changing the position of the brush 34B together with the suction hole 30 by driving the belt 28B, the suction position switching mechanism is provided. The interlocked brush 34B is driven.
- Fig. 13A shows a cross-sectional view of the suction nozzle and air filter during cleaning!
- the solid line arrow in the figure indicates the wind of suction
- the white arrow indicates the cleaning progress direction of the suction nozzle.
- the dimension d in the figure indicates the distance between the front end of the suction hole 30 of the suction nozzle and the air filter. Since the wind from the suction hole 30 diffuses away from the suction hole 30, the wind speed decreases rapidly. Since the cleaning performance by suction depends on the suction bow I wind speed on the air filter surface, it is necessary to keep the distance between the suction hole 30 and the air filter as close as possible. Ideally, d is preferably about 0.5 mm.
- the air filter has many portions that are bent due to molding shrinkage of the filter frame 10 and the filter network 12 during processing that is not completely flat. If the air filter bends toward the suction arch I side, the front end of the suction nozzle may come into contact with dust, and if this happens at a part other than the position of the suction hole 30, the dust will be attracted or dropped. Problems occur. For this reason, d must be designed so that the front end of the suction nozzle and the air filter do not come into contact with each other even when the maximum deflection is taken into account. Since the air filter actually has a maximum deflection of lmm, d is designed to be 1.5mm at the center in the width direction of the suction nozzle.
- the suction air is considerably diffused on the surface of the air filter, and the suction force is considerably reduced.
- the deflection may be deflected to the opposite side of the suction hole 30, where d is a maximum of 2.5 mm away, and the suction force is further weakened. It is necessary to ensure proper cleaning performance. Although it is sufficient to increase the output of the suction device, it increases the size of the device and increases noise. Further, if the suction hole 30 is made smaller, the suction wind speed increases, but it takes a long time to clean the entire air filter.
- the suction hole 30 is surrounded by the brush 34B, and the brush 34B has a height of 2.5 mm or more so that it comes into contact with the air filter even when d is a maximum of 2.5 mm away.
- the brush 34B acts as a wall to suppress the diffusion of wind from the suction hole 30, and a strong suction force can be maintained even on the air filter surface.
- cleaning assistance with the brush 34B can be obtained, it is suitable for cleaning air filters that contain a large amount of oil and that are very difficult to be aspirated.
- the brush 34B is formed so as to surround the suction hole 30, it is possible to prevent the spread of suction air and to increase the wind speed over the entire air filter.
- Embodiments 1 to 3 the force using the suction position switching mechanism using the belt is used, so that the brush contacts the air filter only in the vicinity of the suction position using a different suction position switching mechanism.
- the same effect can be obtained.
- the above-described brush can be used as long as the cleaning is performed by suction, and the present invention is not limited to the suction nozzle having the suction position switching mechanism.
- the brush is not limited to a so-called bristle brush as long as it has an effect of peeling off dust on the air filter.
- the filter device of the air conditioner according to the present invention is a powerful air filter that uses both suction and a brush while preventing dust from dropping even at the vertical part of the air filter. It can be used for various types of air filters, and not only air filters for air conditioners but also air filters such as devices with cooling fans (for example, air filters for stable power supplies) It can also be applied to filter devices for cleaning.
