The indoor unit of the air conditioner may be a hanging machine or a cabinet machine.
In an embodiment of the present invention, referring to fig. 1 to 3, the dust box assembly 10 includes: the box body 11, the cover body 12, the connecting piece 13 and the first resetting piece 14. The box body 11 is provided with a dust collection port 111 and a dust discharge port 112 which extend along a first direction, the cover body 12 is movably mounted on the box body 11 through the connecting piece 13, so that the cover body 12 can move to a dust collection position where the dust collection port 111 is completely opened and a dust discharge position where the dust collection port 111 is partially covered after being stressed relative to the box body 11, and the first reset piece 14 is used for driving the cover body 12 to reset from the dust discharge position to the dust collection position.
The case 11 has a length, a height and a width, and for convenience in describing the dust collecting case assembly 10, the length direction of the case 11 is a first direction, the height direction of the case 11 is a second direction, and the width direction of the case 11 is a third direction, that is, the dust collecting opening 111 on the case 11 extends along the length direction of the case 11, the length of the dust collecting opening 111 is approximately equal to the length of the case 11, and when the case 11 is mounted in the air conditioning indoor unit 100, the dust collecting opening 111 is disposed toward the filter screen 30, so that dust brushed from the filter screen 30 is conveniently collected.
The dust collection port 111 may be formed by penetrating all of one side wall of the case 11 in the longitudinal direction thereof, or may be formed by penetrating one side wall portion of the case 11 in the longitudinal direction thereof, and in view of a relatively small volume of dust brushed off the filter screen 30, the dust collection port 111 is preferably formed by penetrating one side wall portion of the case 11 in the longitudinal direction thereof. The dust collection port 111 and the dust discharge port 112 may be provided on the same side wall of the case 11, and of course, the dust collection port 111 and the dust discharge port 112 may be provided separately on two different side walls of the case 11, and the relative positions of the dust collection port 111 and the dust discharge port 112 are not particularly limited.
In addition, the case 11 may be integrally formed, or may be formed by splicing two shells, and the manner in which the case 11 is formed is not particularly limited. In the embodiment of the invention, the box 11 is formed by splicing two shells, one of the two shells is provided with a plurality of buckling tables, the other of the two shells is correspondingly provided with a plurality of buckling positions, and after the two shells are spliced, the two shells are buckled and fixed with the buckling positions at the corresponding positions through the buckling tables, so that the box 11 is convenient to disassemble and assemble, and meanwhile, the box 11 is convenient to clean, and the box 11 can be cleaned in all directions.
The cover 12 is provided in a plate shape, and is mounted on a side of the box 11 where the dust collecting opening 111 is provided, and the cover 12 is movably connected with the cover 12 through the connecting piece 13, so that the cover 12 is driven by an external force to move relative to the box 11 due to the movable connection between the cover 12 and the box 11, and the cover 12 has a dust collecting position where the dust collecting opening 111 of the box 11 is completely opened and a dust discharging position where the dust collecting opening 111 of the box 11 is partially covered. Specifically, when the cover 12 is switched between the dust collecting position and the dust discharging position, the cover 12 moves in the second direction relative to the case 11 while moving in the first direction relative to the case 11, that is, when the cover 12 moves relative to the case 11, the cover 12 has a speed in the first direction and a speed in the second direction, which causes the cover 12 to move obliquely.
In order to ensure that the cover 12 covers only the dust collecting opening 111 of the case 11 when the cover 12 is in the dust discharging position, the length of the cover 12 in the first direction may be smaller than the length of the dust collecting opening 111 in the first direction, or the width of the cover 12 in the second direction may be smaller than the width of the integration opening in the second direction. Preferably, when the cover 12 is at the dust discharging position, the position of the cover that does not cover the dust collecting opening 111 and the dust discharging opening 112 are disposed at intervals in the length direction of the dust collecting opening 111; preferably, when the cover 12 is in the dust discharging position, the position of the dust collecting opening 111 and the two ends of the dust discharging opening 112 in the length direction of the dust collecting opening 111 are not covered, so that the dust in the dust collecting opening 111 can be sucked out.
The first restoring member 14 can deform when being subjected to external force, the first restoring member 14 can recover elastic deformation when not being subjected to external force, the first restoring member 14 is arranged between the box body 11 and the cover body 12, the first restoring member 14 deforms and has a certain torsion when the cover body 12 is driven to move from a dust collecting position to a dust discharging position by external force, and the cover body 12 moves from the dust discharging position to the dust collecting position under the action of the first restoring member 14 when the external force applied to the cover body 12 is removed.
According to the technical scheme of the invention, the box body 11 of the dust collecting box assembly 10 is provided with the dust collecting opening 111 and the dust discharging opening 112 which extend along the first direction, the cover body 12 of the dust collecting box assembly 10 is movably arranged on the box body 11 through the connecting piece 13, so that the cover body 12 can move to a dust collecting position for completely opening the dust collecting opening 111 and a dust discharging position for partially sealing the dust collecting opening 111 after being stressed relative to the box body 11, and the first reset piece 14 of the dust collecting box assembly 10 is used for driving the cover body 12 to reset from the dust discharging position to the dust collecting position. When cleaning the dust in the box 11, only an external force is applied to the cover 12 to drive the cover 12 to move from the dust collecting position to the dust discharging position, at this time, only part of the dust collecting opening 111 is not covered by the cover 12, and when the dust collector is inserted into the box 11 from the dust discharging opening 112 of the box 11 and sucks the dust in the box 11, because air can only enter the box 11 from the position where the dust collecting opening 111 is not covered by the cover 12 and exit from the dust discharging opening 112 of the box 11, the dust in the box 11 flows to the dust discharging opening 112 along with the flowing air, thereby facilitating the discharge of the dust in the box 11 and further facilitating the cleaning of the dust in the box 11. Compared with the prior art, when the dust collecting box assembly 10 is used for cleaning dust, the dust collecting box assembly 10 is detached from the air conditioning indoor unit 100, and the dust collecting box assembly 10 can be cleaned without being detached from the air conditioning indoor unit 100, so that the dust collecting box assembly 10 is more convenient and simpler when cleaning dust, is convenient for the operation of a user, and is further beneficial to improving the experience of the user.
It should be noted that, to realize the movement of the cover 12 relative to the case 11, there are a plurality of connectors 13 that move the cover 12 in the first direction and also move in the second direction, as long as the connectors 13 can limit the movement of the cover 12 relative to the case 11, and the movement track of the cover 12 extends in the second direction and is inclined in one direction. In an embodiment of the invention, referring to fig. 2, the connecting member 13 is a connecting arm, one end of which is pivotally connected to the case 11, and the other end of which is pivotally connected to the cover 12. Because the cover 12 and the box 11 are separately arranged, and the cover 12 and the connecting arm are pivoted, the connecting arm can drive the cover 12 to swing together when rotating along one end pivoted with the box 11, so that the cover 12 can displace in a first direction and also can generate a position in a second direction when the box 11 rotates from a dust collecting position to a dust discharging position, and therefore, when the cover 12 rotates relative to the box 11, the cover 12 can move along the first direction and also can move along the second direction.
It should be noted that, the number of the connecting arms connecting the cover 12 and the case 11 may be one or more, preferably, a plurality of the connecting arms, one end of each connecting arm is pivotally connected to the case 11, the other end of each connecting arm is pivotally connected to the cover 12, and any two connecting arms are parallel at any time.
In another embodiment of the present invention, the connecting piece 13 may be a sliding rail and a sliding block separately provided on the cover 12 and the box 11, where the sliding rail extends along the second direction and is disposed obliquely along the first direction, and the sliding block is slidably connected with the sliding rail. Since the slider can only slide along the sliding rail, it is determined that the movement track of the cover 12 is consistent with the extending direction of the sliding rail when the cover 12 slides relative to the box 11, so that the cover 12 can move along the second direction and also move along the first direction when sliding relative to the box 11.
It should be noted that the first reset member 14 for automatically switching the cover 12 from the dust discharging position to the dust collecting position is of various kinds, for example: torsion springs, tension springs, compression springs, etc., are not specifically exemplified herein. In an embodiment of the present invention, referring to fig. 1, the first restoring member 14 is a torsion spring, and the torsion spring includes a main body portion having a spiral shape and two elastic supporting legs respectively disposed at two opposite sides of the main body portion; the inner wall surface of the box body 11 is convexly provided with a rotating shaft extending along a third direction perpendicular to the first direction and the second direction, namely, the rotating shaft extends along the width direction of the box body 11, the main body part of the torsion spring is sleeved on the rotating shaft, one elastic supporting leg of the torsion spring is used for being connected with the box body 11, and the other elastic supporting leg of the torsion spring is used for being connected with the cover body 12.
When the cover body 12 moves from the dust collecting position to the dust discharging position under the action of external force, the two elastic supporting legs of the torsion spring are deformed under the action of external force; when the cover 12 is not acted by external force, the two elastic supporting legs of the torsion spring recover the elastic deformation and drive the cover 12 to move from the dust discharging position to the dust collecting position.
In order to apply an external force to the cover 12 to drive the cover 12 to switch between the dust collecting position and the dust exhausting position, in an embodiment of the present invention, referring to fig. 1, 4 and 5, the dust collecting box assembly 10 further includes a driving assembly 15, where the driving assembly 15 is mounted on the box 11 and is capable of driving the cover 12 to move relative to the box 11 when triggered, so that the cover 12 can switch between the dust collecting position and the dust exhausting position.
Specifically, the driving member includes a driving box 151 fixedly connected with the box body 11 and a driving switch 152 installed in the driving box 151, wherein the driving box 151 is provided with a transfer channel 1511 with one end communicated with the dust exhaust port 112, the driving switch 152 is movably installed in the driving box 151, and the switch has a working position extending out of the driving box 151 and an idle position retracted into the driving box 151.
