The invention provides a floor type air conditioner indoor unit.
In an embodiment of the present invention, as shown in fig. 1 to 11, the floor-type air conditioner indoor unit includes a housing 100, an ejector frame 200, a fan assembly (not shown), and a driving device 400. The casing 100 has an air inlet 110, the casing 100 is provided with an upwardly open mounting opening 120, and an air duct 130 is formed between the air inlet 110 and the mounting opening 120. The top-outlet frame 200 is mounted at the mounting opening 120 so as to be movable up and down, the lower end and the front end of the top-outlet frame 200 are opened, and a positioning shaft 210 is provided on a side wall surface of the top-outlet frame 200. A fan assembly (not shown) is installed in the air duct 130 to blow air from the air inlet 110 toward the lower port 220 of the top outlet frame 200 and from the front port 230 of the top outlet frame 200. The driving device 400 is mounted on the housing 100, the driving device 400 includes a driving member 410 and a motion conversion member 420 in transmission connection, the motion conversion member 420 is connected to the top-outlet frame 200, and the driving member 410 is used for driving the motion conversion member 420 to move along a first direction so as to drive the top-outlet frame 200 to move up and down. Wherein the first direction intersects the up-down direction.
In this embodiment, it is understood that the overall shape of the housing 100 can be selected and set according to the use requirement and design requirement. The floor type air conditioner indoor unit is generally arranged in an extending manner. The cross section of the housing 100 may be circular, elliptical, rectangular, or irregular, and is not particularly limited herein. The cross-sectional shape of the top-outlet frame 200 may be varied, such as circular, oval, rectangular, or irregular. The shape of the air inlet 110 may be circular, rectangular, elliptical, or irregular, or may be a plurality of micropores. The air inlet 110 may be an indoor air inlet 110 and/or a fresh air inlet 110. The mounting port 120 should be sized to allow the top-outlet frame 200 to pass therethrough. In order to make the air leakage preventing effect and the moving effect of the top outlet frame 200 better, the shape and size of the mounting opening 120 may be adapted to the shape and size of the top plate of the top outlet frame 200. The mounting opening 120 may be provided on the top plate of the housing 100, or may be provided at another position, so that the opening of the mounting opening 120 is only required to be upward, and the top-outlet frame 200 can be moved up and down. A heat exchanger may be disposed in the air duct 130 to blow out cold air or hot air after heat exchange.
The top-outlet frame 200 may be mounted on the housing 100, or may be mounted on other structures inside the housing 100, so long as the top-outlet frame 200 is correspondingly mounted at the mounting opening 120. The top-outlet frame 200 may be moved up and down by manual adjustment, or the top-outlet frame 200 may be driven to move up and down by the driving device 400. The top-outlet frame 200 can slide up and down through a grooved rail structure, and can also move up and down through a screw adjusting structure, a screw rod structure, a gear rack 423 structure and the like. It is understood that the top-outlet frame 200 has a thin-walled cavity structure. The front end of the top outlet frame 200 is the front end of the floor type air conditioner indoor unit that faces the user after being installed in place. The lower port 220 refers to an opening at the lower end of the top-outlet frame 200, and the front port 230 refers to an opening at the front end of the top-outlet frame 200. By having the lower and front ends of the top-outlet frame 200 open, airflow flows into the cavity of the top-outlet frame 200 from the lower port 220 of the top-outlet frame 200 and is able to flow out from the front port 230.
The housing 100 may be a single-layer shell structure, and the air duct 130 is formed in the single-layer housing 100, so that the mounting opening 120 with an upward opening is disposed on the single-layer housing 100, and the top air frame 200 may extend out of the housing 100. The top-outlet frame 200 may be disposed to extend out of the housing 100 entirely, i.e., the top-outlet frame 200 is disposed to extend out of the housing 100 during the up-and-down movement. In this way, the front port 230 of the top-outlet frame 200 is always communicated with the indoor space, and the top-outlet height and the outlet range of the top-outlet frame 200 can be adjusted by moving the top-outlet frame 200 up and down. It is also possible to have the top-outlet frame 200 move to a position protruding from the housing 100 and to a position accommodated under the mounting port 120. In this way, when it is necessary to realize the top outlet, by moving the top outlet frame 200 to a position where it protrudes from the housing 100, the airflow can be blown out from the front port 230. And when the top-outlet mode is not required, the housing 100 may block the front port 230 of the top-outlet frame 200 by moving the top-outlet to a position accommodated under the mounting port 120 so that the air flow is not blown out from the front port 230. So for the air supply mode is more diversified, simultaneously when need not use the top-outlet mode, can descend top-outlet frame 200 to in the casing 100, and then reduce the height of complete machine for the occupation space of complete machine is little.
In an embodiment, referring to fig. 3, 4, 6 and 8, the housing 100 includes a casing (not shown) and an air duct housing 150 mounted in the casing (not shown), the mounting opening 120 is located on a top surface of the air duct housing 150, the air duct housing 150 forms an air duct 130 therein, and the top air frame 200 is mounted on the air duct housing 150 in a vertically movable manner. The air inlet 110 may be disposed on the air duct housing 150 or on a housing (not shown). The air entering the air duct 130 may be ventilation air, indoor air, fresh air, or other purified air flow. A heat exchanger or the like may be provided in the duct 130. It will be appreciated that the outer shell (not shown) is adapted to the shape of the air duct housing 150. The air duct housing 150 may be integrally formed, or may be formed by splicing two sub-housings. Sufficient space for movement may be left between the top plate of the housing (not shown) and the top plate of the duct housing 150, or may be provided by a fit, or with a small gap. Then, when there is enough space between the top plate of the housing (not labeled) and the top plate of the air duct housing 150, the top air frame 200 can move up and down in the housing (not labeled), at this time, the air outlet 141 can be arranged corresponding to the front port 230 of the top air frame 200 by opening the air outlet 141 on the housing (not labeled), and the extension length of the air outlet 141 can be greater than or equal to the movement stroke of the top air frame 200, and then the air outlet height of the front port 230 can be adjusted by adjusting the up-down movement position of the top air frame 200.
Of course, an extension port may be provided on the top plate of the outer case (not shown) corresponding to the mounting port 120 of the air duct case 150, so that the top air frame 200 may extend. In this way, the air flow can be directly blown from the front port 230 of the top outlet frame 200 into the room, and the height of the housing (not shown) is reduced, so that the whole machine is smaller in size. At this time, the top air frame 200 can be extended out of the housing (not labeled) all the time, and then the height of the air outlet can be adjusted by adjusting the extending height of the top air frame 200, so that the air supply range is enlarged, and different air supply requirements of users are met. In one embodiment, the top-outlet frame 200 has a first position protruding from the mounting opening 120 and a second position hidden from the air duct housing 150, and the driving device 400 is used to drive the top-outlet frame 200 to move between the first position and the second position. In this manner, the top-air frame 200 can be hidden into the duct case 150 when the top-air mode is not required. Thereby reducing the height of the whole machine and the occupied space of the whole machine.
The fan assembly (not shown) may include only one fan, which may be an axial fan, a centrifugal fan, or a cross-flow fan. The opening position of the air inlet 110 may be adjusted according to the type of the fan used, which is not particularly limited herein. May include a wind wheel and a motor, and the wind wheel is driven by the motor to rotate, so that enough air flow is driven to enter the air duct 130 from the air inlet 110, then is blown to the lower port 220 of the top-outlet frame 200, enters the cavity of the top-outlet frame 200, and is blown out from the front port 230 of the top-outlet frame 200.
There are many connection modes between the motion conversion member 420 and the top-outlet frame 200, and only the motion of the motion conversion member 420 along the first direction needs to be converted into the motion of the top-outlet frame 200 along the up-down direction. In an embodiment, a positioning shaft 210 is disposed on a side wall surface of the top-outlet frame 200, a guiding chute 421 is disposed on the motion conversion member 420, and the positioning shaft 210 is disposed through the guiding chute 421, so that when the motion conversion member 420 moves along the first direction, the positioning shaft 210 moves along the guiding chute 421 to drive the top-outlet frame 200 to move up and down.
The positioning shafts 210 may be provided on both left and right side wall surfaces of the top-outlet frame 200, or may be provided on a rear side wall surface of the top-outlet frame 200. The driving member 410 may specifically be a driving motor or other driving member 410 capable of driving the motion converter 420 to move in the first direction. The first direction and the up-down direction can be perpendicular, and can also be set at other included angles. The first direction may be a horizontal direction, i.e., a front-back direction, a left-right direction, or a direction forming an angle with the front-back direction or the left-right direction. The extending direction of the guiding chute 421 may be the front-back direction, the left-right direction, or a certain angle with the front-back direction, the left-right direction, and the up-down direction.
The positioning shaft 210 may extend out of the guiding chute 421 or may just fit into the guiding chute 421. It will be appreciated that the diameter of the positioning shaft 210 should be sized to fit the slot width of the guiding chute 421. The guiding chute 421 is formed on the motion conversion member 420, so that the positioning shaft 210 is disposed through the guiding chute 421. The positioning shaft 210 can be made movable in the extending direction of the guide chute 421. In this way, when the driving member 410 drives the motion converter 420 to move along the first direction, the positioning shaft 210 moves in the guiding chute 421, and further drives the top-outlet frame 200 to move up and down. Through the structure of the positioning shaft 210 and the motion conversion member 420, the up-and-down movement of the top-outlet frame 200 can be realized only by arranging the positioning shaft 210 on the top-outlet frame 200, so that the structure of the top-outlet frame 200 is simpler, the overall weight of the top-outlet frame 200 is reduced, and the driving force required for driving the top-outlet frame 200 to move up and down is smaller. Meanwhile, the driving mode is simple and reliable, the driving mode is easy to realize, the required moving space is small, the whole structure is more compact, and the whole size is reduced. In other embodiments, the positioning shaft 210 may be further disposed on the motion conversion member 420 by disposing the guiding chute 421 on the top-outlet frame 200, so as to convert the motion of the motion conversion member 420 along the first direction into the movement of the top-outlet frame 200 along the up-down direction.
The floor type indoor unit of the present invention is provided with the mounting opening 120 having an upward opening on the housing 100, such that the top air frame 200 is mounted at the mounting opening 120 to be movable up and down, and the lower end and the front end of the top air frame 200 are opened, and the fan assembly (not shown) is used to blow air flow from the air inlet 110 to the lower port 220 of the top air frame 200 and from the front port 230 of the top air frame 200. So that the floor type air conditioner indoor unit has the top outlet mode and the top outlet frame 200 can be moved up and down, it is convenient to adjust the outlet height of the front port 230 of the top outlet frame 200, or it can be lowered into the housing 100 when the top outlet frame 200 is not required to be used. Therefore, the floor type air conditioner indoor unit has various air supply modes and wider air supply range.
Meanwhile, the motion conversion member 420 is connected to the top-outlet frame 200, and the driving member 410 is configured to drive the motion conversion member 420 to move along a first direction, so as to drive the top-outlet frame 200 to move up and down, where the first direction intersects with the up-down direction. So that the motion converter 420 can convert the motion in the first direction into the up-down motion of the top-outlet frame 200 when the driving member 410 drives the motion converter 420 to move in the first direction. The driving structure transfers the moving part in the up-down direction to the first direction, so that the space for the top-off air frame 200 to move in the up-down direction is reduced, the overall structure is more compact, the whole volume is further reduced, and the whole driving mode is simple in structure and convenient to realize.
In practical applications, referring to fig. 4, 5,7 and 9, the first direction is perpendicular to the up-down direction, and the guiding chute 421 is disposed at an angle to the first direction and the up-down direction. By setting the first direction to be perpendicular to the up-down direction, the first direction may be the front-back direction or the left-right direction. When the first direction is the front-rear direction, the positioning shafts 210 are provided on the left and right side wall surfaces of the top-outlet frame 200; when the first direction is the left-right direction, the positioning shaft 210 is provided on the rear sidewall surface of the top-outlet frame 200. The extending direction of the guiding chute 421 is set at an included angle to the first direction and the up-down direction. In this way, when the positioning shaft 210 moves in the guide chute 421, the movement of the motion converter 420 in the first direction can be converted into the up-down movement. The angle between the guiding chute 421 and the up-down direction is greater than 0 degrees and less than 90 degrees. Preferably 30 to 60 degrees. The angle between the guide chute 421 and the up-down direction may be 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, etc. In this way, the guide chute 421 is enabled to better convert the movement of the movement conversion member 420 in the first direction into the up-and-down movement of the top-outlet frame 200.
In an embodiment, referring to fig. 6, 8 and 10, a guiding chute 151 extending along the up-down direction is formed on a side wall of the air duct housing 150, the driving device 400 is disposed on the outer side of the air duct housing 150, the guiding chute 421 is disposed corresponding to the guiding chute 151, and the positioning shaft 210 penetrates the guiding chute 151 to connect with the guiding chute 421.
In the present embodiment, by providing the guide chute 151 extending in the up-down direction on the side wall of the duct case 150, the guide chute 151 can play a role in guiding and limiting the positioning shaft 210. Since the top outlet frame 200 is installed at the inner side of the duct case 150 such that the driving device 400 is disposed at the outer side of the duct case 150, the driving device 400 does not interfere with the movement of the positioning shaft 210. So that the positioning shaft 210 is inserted into the guiding chute 151 and then connected to the guiding chute 421. When the driving member 410 drives the motion converter 420 to move along the first direction, the positioning shaft 210 moves along the extending direction of the guiding chute 421, and the positioning shaft 210 can only move up and down in the guiding chute 151 due to the limiting function of the guiding chute 151, so as to prevent the positioning shaft 210 from deflecting, shaking, deviating from the track, and the like. The process of moving the top-out air frame 200 up and down is smoother and more accurate.
Specifically, as shown in fig. 4, 5 and 11, the positioning shaft 210 is disposed on the rear side wall surface of the top-outlet frame 200, the air duct case 150 is provided with a sliding groove 152 extending along a first direction at a position corresponding to the rear side wall surface of the top-outlet frame 200, the motion converter 420 is slidably mounted on the sliding groove 152, the first direction is consistent with the length direction of the air duct case 150, and the guide chute 421 is disposed at an angle to both the first direction and the up-down direction.
In the present embodiment, it is understood that the height direction of the air duct case 150 coincides with the up-down direction, and the length direction of the air duct case 150 coincides with the plate length direction of the top plate thereof. The first direction is the right-left direction when the first direction coincides with the longitudinal direction of the duct case 150. By providing the positioning shaft 210 on the rear side wall surface of the top-outlet frame 200, and the first direction is consistent with the longitudinal direction of the duct case 150, the path along which the motion converter 420 moves in the first direction is longer with respect to the positioning shaft 210 provided on the left and right side wall surfaces of the top-outlet frame 200, and thus the vertical movement stroke of the top-outlet frame 200 can be made longer. By providing the sliding groove 152 along the first direction on the rear sidewall surface of the top-outlet frame 200, the motion conversion member 420 may be slidably mounted in the sliding groove 152, and the sliding groove 152 may provide a sliding space for the motion conversion member 420, so that the motion conversion member 420 may move more smoothly along the first direction. Meanwhile, the motion conversion member 420 can drive the top-outlet frame 200 to move up and down only by requiring a small moving space, so that the whole driving device 400 occupies a small space and the whole structure is more compact.
In combination with the above embodiment having the sliding groove 152, further, as shown in fig. 3, 7 and 9, the driving device 400 further includes a pressing plate 430, where the pressing plate 430 is connected to the housing 100 and covers the sliding groove 152, so that the motion converter 420 is slidably mounted in the sliding groove 152 along the first direction.
In this embodiment, the pressing plate 430 may be connected to the housing 100 by means of screws, clamping, bonding, welding, etc. When the pressing plate 430 is disposed to cover the sliding groove 152, a sliding space is formed between the pressing plate 430 and the inner wall surface of the sliding groove 152, which plays a limiting role on the motion converter 420. In this way, the motion converter 420 can stably slide in the first direction within the slide groove 152.
In an embodiment, referring to fig. 4 to 11, the number of the positioning shafts 210 and the number of the guiding chute 421 are two, each positioning shaft 210 is disposed through one guiding chute 421, and the two guiding chutes 421 are disposed in parallel in the first direction. By providing two positioning shafts 210 and two guiding chutes 421, the two guiding chutes 421 are arranged side by side in the first direction. The up-and-down movement of the top-outlet frame 200 is more stable, and the stress of the single positioning shaft 210 can be reduced, and the service life of the positioning shaft 210 can be prolonged.
In an embodiment, as shown in fig. 5, 7 and 9, the motion conversion member 420 is further provided with a buffer slot 422, and the buffer slot is disposed at the lower end of the guiding chute 421 and is communicated with the guiding chute 421, and an inclination angle of the buffer slot 422 with respect to a horizontal plane is smaller than an inclination angle of the guiding chute 421 with respect to the horizontal plane, so as to drive the positioning shaft 210 to move from the buffer slot 422 to the guiding chute 421 when the driving member 410 is just started.
It is understood that a horizontal plane refers to a horizontal plane relative to the ground. When the first direction coincides with the up-down direction. The inclination angle of the guiding chute 421 with respect to the horizontal plane is 90 degrees, and the positioning shaft 210 can be buffered and guided only by making the inclination angle of the buffering chute 422 with respect to the horizontal plane smaller than 90 degrees. When the first direction and the up-down direction are disposed at an included angle, the extending direction of the guiding chute 421 should be disposed at an included angle with respect to the first direction and the up-down direction. At this time, the buffer slot 422 and the guide chute 421 should be extended toward substantially the same side, and the inclination angle of the buffer slot 422 with respect to the horizontal plane is smaller than the inclination angle of the guide chute 421 with respect to the horizontal plane. The inclination angles at this time should be all included angles smaller than 90. The buffer slot 422 may be a straight slot or an arc slot, and when the buffer slot 422 is an arc slot, the inclination angle of the buffer slot 422 with respect to the horizontal plane may be the inclination angle of the tangent line of the buffer slot 422, or the curvature of the buffer slot 422 may be smaller than the inclination angle of the guide chute 421. In order to further smoothly move the positioning shaft 210 from the buffer groove 422 into the guide chute 421, it is preferable to smoothly transition the guide chute 421 and the buffer groove 422 of the buffer groove 422.
By making the angle of inclination of the buffer tank 422 with respect to the horizontal smaller than the angle of inclination of the guide chute 421 with respect to the horizontal, the buffer tank 422 is made more gentle with respect to the guide chute 421. When the driving member 410 is just started, if the positioning shaft 210 is directly disposed on the guiding chute 421 due to insufficient driving force, the positioning shaft 210 is not easy to slide along the guiding chute 421 due to too large inclination of the guiding chute 421 with respect to the horizontal plane. Through setting up the buffer tank 422, it is more mild, then when the motor just starts, the locating shaft 210 carries out buffering and removes a period of time in the buffer tank 422, and when the motor normally moves, drive locating shaft 210 by buffer tank 422 smooth movement to direction chute 421, and then smooth removal in direction chute 421.

Of course, the guide chute 421 may also avoid extending to the position of the frame 425. Two opposite racks 423 are arranged in the gear frame 425, so that the meshing area of the gear and the racks 423 is larger, and the gear is easier to drive the racks 423 to move.
In combination with the above embodiment having the driving motor and the transmission gear 440, further, referring to fig. 4 to 9 again, the number of driving motors and the transmission gear 440 is two, each driving motor is fixedly connected with one transmission gear 440, and the two driving motors rotate synchronously.
