Filter cleaning and possess its conditioner
Technical field
Conditioners such as the air conditioner that the present invention relates to clean the clearing apparatus of the filter that airborne dust is removed and carried this clearing apparatus, humidifier, dehumidifier, air cleaning machine, warm-air drier.
Background technology
In the past, as this air conditioner, shown in patent documentation 1, known have the dust box that possesses the brush that dust is removed is contacted with filter and dispose, by filter is moved with the device of the whole dedusting of filter.In addition, shown in patent documentation 2, also known have be provided with can be with the movably suction nozzle that sucks attached to the dust on the filter, intake line is set on this suction nozzle and possesses the attraction exhaust apparatus that is attached to intake line and the dust that sucks filter for installation to the discharge duct of outdoor exhaust.
Patent documentation 1: the spy opens the 2005-188808 communique
Patent documentation 2: the spy opens the 2004-283703 communique
Summary of the invention
But, in above-mentioned patent documentation 1 described air conditioner, owing to just will wipe off attached to the dust on the filter by brush, so might be attached to again on the filter attached to the dust on the brush, in addition, also produced the problem that dust must have been abandoned when in the dust box, having accumulated dust.
On the other hand, in patent documentation 2 described filter for installations, owing to be not that brush will be removed attached to the dust on the filter, but the mode of removing by the attraction of air, so the possibility that does not have the damage filter or in clearing apparatus, accumulate dust.But, in this filter for installation, owing to making the suction inlet contact that is formed on the suction nozzle on filter surfaces, suck dust, if enlarge the scope that sucks dust so increase the area of suction inlet, then attraction dies down, the bigger attraction exhaust apparatus of air requirement for the reduction that prevents efficiency of dust collection, otherwise, improve attraction if reduce the area of suction inlet, then produce the time-consuming problem of the whole filter of cleaning.
So, in the present invention, purpose provide a kind of attraction exhaust apparatus that actual air volume is not bigger when adopting mode dust is removed by fluids such as air, can once carry out filter in a big way dedusting filter cleaning and be equipped with the conditioner of this clearing apparatus.
Relevant filter cleaning of the present invention, it is the filter cleaning that cleans the filter that airborne dust is removed, it is characterized in that, possess that have can be with the dedusting box of filter to the slit of guided inside, with the air miscarriage life structure that in this dedusting box, produces air stream, above-mentioned dedusting mechanism forms more longways in the mode that passes across filter, above-mentioned air miscarriage life structure is by the distolateral air entry of the length direction one that is formed on above-mentioned dedusting box, with to be connected another distolateral and attract the attraction mechanism of air to constitute, distolateral towards another distolateral generation air stream by above-mentioned air miscarriage life structure from the length direction one of above-mentioned dedusting box, will remove attached to the dust on the filter that directs into from above-mentioned slit in the dedusting box by this air stream.
In addition, it is characterized in that above-mentioned dedusting box-like becomes half point and cuts shape, the dedusting box that this half point cuts shape clips filter and is configured in its table back of the body both sides respectively, will be formed on gap between the dedusting box that above-mentioned half point cuts shape as the slit of guiding filter.
According to said structure, to remove attached to the dust on the filter owing to filter is housed in the space that surrounds by two boxes, in this limited space that ventilates, so do not need as attraction mouth mode in the past, to suck air from bigger suction inlet.Thereby as the mechanism that ventilates, the bigger structure of air requirement is not installed and can not maximized.
And then, can easily accelerate the flow velocity of air, can will blow expeditiously attached to the dust on the filter by this air stream and fly to remove.Here, half point cut shape the dedusting box if its opening surface to box to each other can be involutory the landform achievement passable, do not need to form identical shape.
As the air miscarriage life structure that in above-mentioned box, produces air and ventilate, can use and for example possess fan, air is taken into the structure that is taken into mouthful and discharges from fan the liberation port of air in this fan, be connected on the box by this being taken into mouth and liberation port, air circulation is passed in the box.
In addition, as other air miscarriage life structures, also can use air delivering mechanism that air is sent or the air that attracts air to attract mechanism.In the case, by on box, forming blow vent, air is circulated between blow vent and air delivering mechanism or air attraction mechanism.But,, preferably use air to attract mechanism from the viewpoint that dust can not disperse towards periphery from the gap of box and box.
The sectional area of air flow circuit is more little, can make the flow velocity of flow air in air flow circuit become big more.That is, as the dedusting box, even the area of the opening surface that half point cuts is identical, the structure that slenderly forms can make the flow velocity of flow air in air flow circuit become big more.In other words, if the sectional area of air flow circuit is less,, also less to the influence of the flow velocity of flow air in air flow circuit even then make the length of air flow circuit elongated.
Thereby, if dedusting box air flow circuit sectional area is less, form more longways even then pass across filter, also can easily produce flow velocity air stream faster.Particularly, if attract the attraction mechanism of air at the filter cross-directional one distolateral formation air entry of box, in another distolateral connection, then can in whole air flow circuit, produce flow velocity air stream faster, can will remove expeditiously thus attached to the dust on the filter in the air flow circuit.
Above-mentioned filter cleaning also can be provided with the travel mechanism that on the direction with respect to the length direction quadrature of dedusting box filter is relatively moved.Thus, can automatically clean whole filter.Travel mechanism both can make filter move with respect to fixing dedusting box, and the dedusting box is moved with respect to fixing filter.
The slit of dedusting box or the gap thickness than filter are big, more travel mechanism are successfully moved, and opposite, air flow in the box from the gap, and the flow velocity of the air that circulates in air flow circuit reduces.Otherwise if make the slit or the gap smaller of dedusting box, then when making travel mechanism's action, the open end contact of box makes attached to the dust on the filter and disperses towards periphery on the dust of filter surfaces.
So, in the present invention, it is roughly the same with the width of dedusting box that a plurality of cross ribs, this cross rib that filter possesses prominent shape vertically equally spaced dispose, form the interval that makes between cross rib along filter, above-mentioned slit-shaped become that the cross rib of above-mentioned filter can pass through the interval, make travel mechanism's action and make cross rib be positioned at the position that the slit of dedusting box is stopped up.
According to said structure, two boxes separate gap that cross rib can pass through and arranged opposite.That is, because box disposes under the state that leaves from filter surfaces, so even make travel mechanism's action, box can not contact on filter surfaces yet and dust is dispersed.
In addition, be positioned between the open end of two boxes, can enough cross ribs be stopped up by the slit or the gap of dedusting box by making cross rib.Like this, can and be clipped in the box body that cross rib between it forms tubular by two boxes, by make the attraction mechanism action under this state, the flow velocity that can not make the air that flows through air flow circuit reduces and cleans the partition that is surrounded by cross rib expeditiously.
If the cleaning of a partition finishes, then will attract mechanism to stop, as long as make filter move interval between cross rib, just adjacent partition can being accommodated in the box body, so, by the repetition aforesaid operations, can carry out the cleaning of filter according to partition.That is,, just can dust be dispersed and scavenge filter only by travel mechanism is moved off and on.
In addition, the another kind of structure of dispersing as the dust that prevents filter surfaces, filter part timesharing that also can be in cleaning enters into air flow circuit, travel mechanism is stopped, make dedusting box contact on filter and form air flow circuit, after the cleaning of filter part finishes, under the state that the dedusting box that is configured in the filter surfaces side that is attached with dust is left from filter, make travel mechanism's action, the filter of not cleaning is partly entered in the air flow circuit.
Particularly, for example if be configured such that on the basis that itself and the distance of filter can change at the dedusting box that the half point that will be configured in the filter surfaces side cuts shape, the active force by spring supports so that its always from filter leave, that the active force that overcomes spring by solenoid etc. during at filter cleaning is connected on the filter box is just passable.
In addition, also can on the surface of above-mentioned filter, longitudinally form the cross rib of the prominent shape of multiple row, above-mentioned dedusting box possesses in inside and is formed with the guiding walls that longitudinally forms on the box main body of air flow circuit and the vertical both ends at this box main body, form, make the longitudinal length of this guiding walls longer than the inside dimension of adjacent cross rib.
In said structure, on vertical both ends of the box main body of dedusting box, form guiding walls, form and make the length longitudinally of guiding walls longer, so in being guided the space that wall clips, always have cross rib than the inside dimension of adjacent cross rib.That is, can in the filter guide path that the slit that utilizes the dedusting box or gap are passed through as filter, this slit or gap be stopped up, come limit air turnover therefrom by cross rib with the prominent shape in cross section.More particularly, the dedusting box preferably is configured to, and makes the length at vertical both ends of box main body parallel with the length direction of cross rib.
Thus, can be suppressed at the reduction of the flow velocity of the air that circulates in the space that surrounds by the box main body of dedusting box, can will blow expeditiously attached to the dust on the filter that is contained in the dedusting box by this air stream and fly to remove.
As relevant filter cleaning of the present invention, also can constitute, except said structure, also in the dedusting box, possess along the cleaning brush of its length direction configuration, make above-mentioned filter edge relatively mobile on one side with the direction of the length direction quadrature of dedusting box, make above-mentioned cleaning brush rotation on one side and the lip-deep dust attached to filter is broken away from, and remove from the dedusting box by the dust that above-mentioned air miscarriage life structure will float.
According to said structure, owing to make the filter edge relatively mobile on one side with respect to the direction of the length direction quadrature of dedusting box, make cleaning brush rotation driving on one side and the lip-deep dust attached to filter is broken away from, and will break away from the dust that floats by air miscarriage life structure and use the air that produces by air miscarriage life structure to flow to discharge to the outside, so also can it be floated and remove even adhere to lip-deep stubbornness dirty of filter from the dedusting box.
In addition,, also can possess the motor that rotation drives cleaning brush, make cleaning brush rotation driving and the lip-deep dust attached to filter is broken away from by motor as filter cleaning.
At this moment, the direction of rotation of cleaning brush can be set as follows.That is, the control motor is so that the direction of rotation of cleaning brush is a certain orientation.Such control is certain orientation owing to making the direction of rotation of motor, so become simple control.In addition, the direction of rotation of Ci Shi cleaning brush is preferably to rotating with respect to the opposed direction of past filter moving or that return.In addition, cleaning brush in coming and going of filter is moving the rotation drive ratio is returned when moving the time rotation driving easier will the removing of situation attached to the lip-deep dust of filter.
In addition, motor also can be set at, and the rotor-position when making it corresponding to its voltage starting decides the direction of rotation of motor, and the direction of rotation that makes cleaning brush is direction arbitrarily.
According to said structure and since the direction of rotation of motor during according to voltage starting rotor-position and forward or reverse, so direction of rotation changes with 1/2 probability.Therefore, compare to the situation that a direction is rotated, cleaning brush also only rotates to a direction with motor, dust ground, front and back on filter moves back and forth, and can prevent that on long terms dust from accumulating on the end of filter.
And then, also can be to the motor SECO, so that its direction of rotation is by positive rotation and contrary constituting of rotating.By said structure, the complexity though control can become slightly can prevent reliably that dust from accumulating on the end of filter.
Cleaning brush is not particularly limited its shape, but can illustration have the structure that is configured in the multi-disc elastic scraper on every side of rotating shaft with helical form.According to this structure, can not injure filter by the multi-disc elastic scraper, can reliably the dust on the filter surfaces be removed.
In addition, be formed on the extend axially setting of another distolateral elastic scraper of rotating shaft along rotating shaft, this extension portion of setting be configured in rotating shaft bearing portion around.According to this structure, the air that can prevent to contain the dust that is attracted invades the bearing portion from the end of scraper plate.
More than Shuo Ming filter cleaning is possessing suction inlet and blow-off outlet and is being clipped between it and in the conditioner of the filter that airborne dust is removed, conditioner is maximized and the additional filter cleaning function by carrying.Conditioner is not particularly limited so long as to possess the structure of filter that airborne dust is removed just passable, for example can enumerate air conditioner, humidifier, dehumidifier, air cleaning machine, warm-air drier etc.
In addition, carry under the situation in conditioner will possessing the filter cleaning that makes the travel mechanism that filter longitudinally moves back and forth, if filter in the past, then owing in order to prevent warpage or fluctuation, to keep conformality and need to a certain degree rigidity, so when filter moves, have to filter is exposed to outside the machine of conditioner, has produced the problem of infringement outward appearance.
So, in the present invention, possess a plurality of cross ribs that filter surfaces are divided into the prominent shape of a plurality of partitions, this cross rib is along vertically equally spaced configuration of filter, it is roughly the same with the width of box to form the interval that makes between this cross rib, two boxes separate the gap arranged opposite that cross rib can pass through, make travel mechanism's action and cross rib is positioned between the open end of two boxes, by two boxes and be clipped in the box body that cross rib between it forms tubular, the clearing apparatus of the structure that will will remove attached to the dust on the filter according to the partition that is housed in this box body carries in conditioner, filter can longitudinally be formed agley, be provided with the filter retainer mechanism that keeps making travel mechanism when action that the filter that is along the longitudinal movement is bent into U font roughly.
According to said structure, even reduce filter intensity and filter is longitudinally formed longitudinally flexiblely, also can keep sufficient conformality by a plurality of cross ribs that are formed on the filter, be housed in the conditioner so can make the filter bending that is along the longitudinal movement, play the effect that can not damage outward appearance.
More than, according to the present invention, owing to make and possess that have can be with the dedusting box of filter to the slit of guided inside, structure with the air miscarriage life structure that in this dedusting box, produces air stream, perhaps making the dedusting box that the half point that inside is formed with air flow circuit cuts shape is configured to make its opening surface opposed each other, the structure of configuration air cleaner in the gap between the dust box (slit), ventilate in the dedusting box and will remove attached to the dust on the above-mentioned filter, so the mechanism that actual air volume is bigger accelerates the speed that is passed to the air in the stream as the mechanism that ventilates, and can fly to remove with blowing expeditiously attached to the dust on the filter thus.

In the above-described embodiment, filter being along the longitudinal movement, but replacing it, also can be the mode that dedusting box and cleaning brush are moved with respect to filter.
[the 4th embodiment]
Based on Figure 19 the 4th embodiment of the present invention is described.In the present embodiment, it is characterized in that controlling the rotation of the electro-motor of the cleaning brush rotation driving that makes in the 3rd embodiment, other structures and the 3rd embodiment are same.
Figure 19 (a), Figure 19 (b), Figure 19 (c) are the synoptic diagrams of filter cleaning of the control method of the different electro-motor of the difference of expression in the present embodiment.In Figure 19 (a), the control part 50 that electro-motor 47 is subjected to be made of microcomputer is controlled, so that the direction of rotation of cleaning brush 41 is a certain orientation.
Such control is certain orientation owing to making the direction of rotation of electro-motor 47, so become simple control.The direction of rotation of the cleaning brush 41 of this moment is driven to rotating with the opposed direction of the moving direction of filter 4 when past the moving of filter 4.For example, shown in Fig. 5 (a), when the A direction moved, the direction of rotation of cleaning brush 41 was driven to rotating with the opposed B direction of A direction, will remove attached to the lip-deep dust of filter 4 easily at filter 4.
In Figure 19 (b), electro-motor is set at the direction of rotation of the rotor-position decision motor when making it according to its voltage starting.Cleaning brush 41 is uncertain to which direction rotation.Usually, in electro-motor 47, the direction of rotation when starting in order to make is that certain orientation is provided with the lockable mechanism (diagram is omitted) of controlling the rotor-position when stopping.This lockable mechanism takes off the formations such as electromagnetic core that are located at freely on the rotor (diagram is omitted) by card, but this lockable mechanism is abandoned as known.So the stop position of rotor becomes uncertain, when restarting, according to the position of its rotor that stops, the direction of rotation of electro-motor 47 is a forward or reverse.
Thereby the cleaning brush 41 that is attached on the electro-motor 47 changes direction of rotation with 1/2 probability.If carry out the control of such electro-motor 47; direction of rotation at motor is a direction; and cleaning brush 41 is also under the situation of a direction rotation; dust might accumulate on the end of filter 4; but because direction of rotation is with 1/2 probability variation; so dust moves back and forth before and after becoming on filter, on long terms, can prevent that dust from accumulating on the end of filter 4.
In Figure 19 (c), carry out SECO by 50 pairs of electro-motors of control part 47, so that its direction of rotation constituting by positive rotation and contrary rotation.In control part 50, for example clean running and in making 10 times of the opposite or cleaning running of direction of rotation for 1 time, make direction of rotation become rightabout control 1 time.
In said structure, the SECO by electro-motor 47 makes control become complicated slightly, but dust can always not accumulate on the end of filter 4 for certain situation as direction of rotation, can reliably the dust on the filter 4 be removed.
In addition, the suction inlet 2 that dedusting box 10,11 spreads all over the left and right sides forms more longways along left and right directions, but also can be to set up reinforcement feature 48 in the centre position of box 10,11 as shown in Figure 16 and the structure reinforced.In the case, run on the reinforcement feature 48 and produce abnormal sound for the elastic scraper 41b that prevents cleaning brush 41 wipes, also can elastic scraper 41b axially on middle body cut away and form recess 49, can avoid reinforcement feature 48 when rotated.
