Description
Technical Field
The invention relates to the technical field of air conditioning, in particular to a vertical air conditioner indoor unit.
Background
The relatively large cold air density tends to sink and the relatively small hot air density tends to rise. Therefore, the air conditioner needs to blow more cold air upwards as much as possible during refrigeration and hot air towards the ground as much as possible during heating, so that the cold air or the hot air can be diffused more uniformly in the indoor space, and the refrigerating and heating speeds are higher.
The existing vertical air conditioner indoor unit is usually provided with a forward air outlet, and air-guiding structures such as an air deflector and a swing blade are utilized to guide the air outlet direction of the air flow of the air supply to realize upward blowing or downward blowing. However, the current air guiding structures have limited air guiding angles, and can only supply air obliquely upwards or downwards, so that cold air or hot air is difficult to reach a roof or floor area, and the refrigerating or heating effect is affected.
Disclosure of Invention
It is an object of the present invention to provide a floor air conditioner indoor unit that overcomes or at least partially solves the above-mentioned problems.
The invention aims to strengthen the upper blowing and lower blowing effects of an indoor unit of a vertical air conditioner.
A further object of the present invention is to facilitate the switching between the up-blowing mode and the down-blowing mode of the indoor unit of the vertical air conditioner.
In particular, the invention provides a vertical air conditioner indoor unit, which comprises a casing provided with an air outlet and a wind scooper ring which is sleeved on the periphery of the casing in a vertically translational manner and is spaced from the periphery of the casing, wherein the wind scooper ring comprises:
The cover ring body is provided with an opening opposite to the air outlet;
The upper guide plate is rotatably arranged at the upper half part of the opening, and defines an upper channel which is opened upwards with the outer peripheral surface of the shell, and the distance between the upper guide plate and the outer peripheral surface of the shell can be adjusted through rotation; and
The lower guide plate is rotatably arranged at the lower half part of the opening, and defines a lower channel which is opened downwards with the outer peripheral surface of the shell, and the space between the lower guide plate and the outer peripheral surface of the shell can be adjusted through rotation;
The air guide cover ring is configured to: the upper channel is communicated with the air outlet, so that the air flow discharged from the air outlet flows upwards along the peripheral surface of the shell; or the lower channel is communicated with the air outlet, so that the air supply air flows downwards along the peripheral surface of the shell.
Optionally, the shroud ring is configured such that when in its up-blowing position, the upper baffle is translatable upwardly away from the lower baffle to allow the supply air flow exiting the outlet to blow directly from the space between the upper and lower baffles.
Optionally, the shroud ring is configured such that when in its down-blowing position, the lower baffle is translatable downwardly away from the upper baffle to allow the supply air flow exiting the outlet to blow directly from the space between the upper and lower baffles.
Optionally, the rotation axis of the upper baffle is adjacent to its bottom end and extends in a horizontal direction, and the rotation axis of the lower baffle is adjacent to its top end and extends in a horizontal direction.
Optionally, the upper deflector comprises an upper deflector main body section extending up and down and an upper deflector bending section bending and extending from the lower end of the upper deflector main body section towards the outer peripheral surface of the casing; the lower guide plate comprises a lower guide plate main body section extending up and down and a lower guide plate bending section bending and extending from the upper end of the lower guide plate main body section towards the outer peripheral surface of the shell.
Optionally, at least one motor is installed on the casing, and a gear is installed on the motor; and the inner side of the air guide cover ring is provided with at least one rack extending along the up-down direction, and each rack is meshed with one gear, so that when the motor drives the gear to rotate, the rack translates up and down to drive the air guide cover ring to translate up and down.
Optionally, the number of the motors, the gears and the racks is two, and the two motors are respectively arranged on two lateral sides of the casing.
Optionally, the air outlet is arranged on the front side of the casing; the two lateral sides of the inner wall of the air guide cover ring are respectively provided with a vertically extending wind shielding strip for blocking the air flow of the air supply to flow backwards; and each wind shielding strip is provided with a rack.
Optionally, an air guiding swing blade for guiding the air flow upwards or downwards is installed at the air outlet.
Optionally, the air outlet is in a strip shape with the length direction along the horizontal direction.
In the vertical air conditioner indoor unit, the air guide cover ring is sleeved on the periphery of the casing and comprises a cover ring body, an upper guide plate and a lower guide plate. The upper guide plate and the outer peripheral surface of the shell define an upward open upper channel, the lower guide plate and the outer peripheral surface of the shell define a downward open lower channel, and the vertical air conditioner indoor unit can have an upward blowing mode and a downward blowing mode by moving the shroud body up and down. For example, when the air conditioner is refrigerating, the air guide cover ring can be moved to an upward blowing position in which the upper channel is communicated with the air outlet, so that the air flow discharged from the air outlet flows upwards along the outer peripheral surface of the casing, and after the cold air in the casing is blown out from the air outlet, the cold air is blocked by the upper guide plate and cannot be directly blown out horizontally, but is blown out upwards along the outer peripheral surface of the casing. Similarly, when the air conditioner heats, the air guide cover ring can be moved to a downward blowing position in which the lower channel is communicated with the air outlet, so that the air supply air flows downwards along the outer peripheral surface of the shell, and the hot air flows downwards along the outer peripheral surface of the shell.
Because the air flow of the air supply clings to the outer peripheral surface of the shell to flow upwards or downwards, the wall attaching effect is formed, the air flow can smoothly reach the roof or the ground along the outer peripheral surface of the shell, the refrigerating or heating effect of the indoor unit of the vertical air conditioner is better, and meanwhile, the discomfort of a human body caused by blowing cold air or hot air can be avoided. The structure of the air guide cover ring is very ingenious and practical, and the appearance of the vertical air conditioner indoor unit is very unique and beautiful.
Further, the indoor unit of the vertical air conditioner can adjust the distance between the upper guide plate and the lower guide plate and the outer peripheral surface of the shell by rotating the upper guide plate and the lower guide plate, so that the air outlet flow, the air outlet speed and the air outlet angle range are changed.
Further, the indoor unit of the vertical air conditioner also has a maximum blowing mode. That is, when the air guide cover ring is at the upper blowing position, the upper guide plate can translate upwards to be far away from the lower guide plate, so that the air flow discharged from the air outlet is allowed to be directly blown out from the interval between the upper guide plate and the lower guide plate, and the air flow is blown out more smoothly, so that the large air volume air outlet is realized.
Further, in the vertical air conditioner indoor unit, the air guide swing blades for guiding the air flow upwards or downwards are arranged at the air outlet, so that the direction change of the air flow is more gentle when the air flow is blown out from the air outlet and then turns upwards or downwards, and the wind loss and noise are reduced.
The above, as well as additional objectives, advantages, and features of the present invention will become apparent to those skilled in the art from the following detailed description of a specific embodiment of the present invention when read in conjunction with the accompanying drawings.

Detailed Description
Hereinafter, a floor air conditioner indoor unit according to an embodiment of the present invention will be described with reference to fig. 1 to 10. Where the terms "front", "rear", "upper", "lower", "top", "bottom", "inner", "outer", "transverse", etc., refer to an orientation or positional relationship based on that shown in the drawings, this is merely for convenience in describing the invention and to simplify the description, and does not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the invention. The flow direction of the supply air flow is shown by arrows.
The embodiment of the invention provides a vertical air conditioner indoor unit which is used for adjusting indoor air, such as refrigeration/heating, dehumidification, fresh air introduction and the like.
Fig. 1 is a schematic view illustrating a structure of a floor air conditioner indoor unit in a down-blowing mode according to an embodiment of the present invention; fig. 2 is a schematic cross-sectional view of the indoor unit of the stand air conditioner shown in fig. 1; FIG. 3 is an enlarged view of the N-N cross-section of FIG. 2; FIG. 4 is an enlarged view at A of FIG. 2; fig. 5 is a schematic view of the indoor unit of the vertical air conditioner shown in fig. 1 when switching to the up-blowing mode.
As shown in fig. 1 to 6, the indoor unit of a floor air conditioner according to an embodiment of the present invention may generally include a cabinet 10 and a cover ring 20. An air outlet 12 is provided in the casing 10 for discharging the air flow of the air supply in the casing 10 into the room. The air flow can be cold air produced by the indoor unit of the vertical air conditioner in a refrigerating mode, hot air produced by the indoor unit of the vertical air conditioner in a heating mode, or fresh air introduced in a fresh air mode, and the like. The air outlet 12 may be provided in a front upper region of the cabinet 10, referring to fig. 1.
The air guide cover ring 20 is vertically and translatably sleeved on the outer periphery of the casing 10, and is spaced from the outer periphery of the casing 10 to allow air flow to pass through. The air guide shroud 20 includes a shroud body 26, an upper baffle 27, and a lower baffle 28. The shroud body 26 has an opening 261 opposite the air outlet 12. The upper baffle 27 is rotatably installed at an upper half of the opening 261, and defines an upper passage 273 opened upward with the outer circumferential surface of the cabinet 10, and is rotatably adjustable in its distance from the outer circumferential surface of the cabinet 10. The lower baffle 28 is rotatably installed at the lower half of the opening 261, and defines a lower passage 283 opened downward with the outer circumferential surface of the casing 10, and is rotatably adjustable in its distance from the outer circumferential surface of the casing 10.
The cowl ring 20 is configured to: an upward blowing position in which the upper duct 273 communicates with the air outlet 12 so that the air flow discharged from the air outlet 12 flows upward along the outer peripheral surface of the casing 10; or to a down-blowing position where the lower passage 283 communicates with the air outlet 12 so that the supply air flow flows downward along the outer circumferential surface of the casing 10. The space between the cover ring 20 and the outer peripheral surface of the cabinet 10 is formed with an air guide passage 21 to allow a part of the supply air flow to flow upward or downward along the outer peripheral surface of the cabinet 10 under the guide of the air guide passage 21.
The vertical air conditioner indoor unit of the embodiment of the invention has an up-blowing mode and a down-blowing mode, and the up-blowing mode and the down-blowing mode can be switched by moving the air guide cover ring 20 up and down. For example, when the air conditioner is cooled, the air guide cover ring 20 may be moved to an upward blowing position in which the upper duct 273 communicates with the air outlet 12, so that the air flow discharged from the air outlet 12 flows upward along the outer peripheral surface of the casing 10, and after the cold air in the casing 10 is blown out from the air outlet 12, the cold air is blocked by the upper baffle 27 and cannot be directly blown out horizontally, but is blown out upward along the outer peripheral surface of the casing 10. Similarly, when the air conditioner heats, the air guide cover ring 20 is moved to a down-blowing position in which the lower passage 283 communicates with the air outlet 12 so that the air flow flows downward along the outer peripheral surface of the casing 10, and the hot air flows downward along the outer peripheral surface of the casing 10.
Because the air flow of the air supply is tightly attached to the outer peripheral surface of the shell 10 to form a wall attaching effect, the air flow can smoothly reach the roof or the ground along the outer peripheral surface of the shell 10, so that the refrigerating or heating effect of the indoor unit of the vertical air conditioner is better, and meanwhile, the discomfort of a human body caused by blowing cold air or hot air can be avoided. The structure of the air guide cover ring 20 is very ingenious and practical, and the appearance of the indoor unit of the vertical air conditioner is very unique and attractive.
In addition, the indoor unit of the vertical air conditioner according to the embodiment of the invention can adjust the distance between the upper deflector 27 and the lower deflector 28 and the outer circumferential surface of the casing 10 by rotating them, thereby changing the air outlet flow, the air outlet speed and the air outlet angle range.
For example, as shown in fig. 2 and 4, the rotation axis x1 of the upper baffle 27 may be adjacent to the bottom end thereof and extend in the horizontal direction, and the rotation axis x2 of the lower baffle 28 may be adjacent to the top end thereof and extend in the horizontal direction. As shown in fig. 2, the lower baffle 28 may be rotated to move its lower end away from the casing 10, so that the area of the opening 261 of the lower channel 283 is larger, and the air outlet flow rate is larger, and the air outlet angle range is larger.
The upper baffle 27 and the lower baffle 28 may also be configured to rotate to a closed position in which both lateral edges thereof are in close contact with both lateral edges of the opening 261 to close the opening 261. When the vertical air conditioner indoor unit is shut down, the upper guide plate 27 and the lower guide plate 28 can be adjusted to the closed positions, so that the three parts form a complete annular structure, and the appearance of the vertical air conditioner indoor unit is more complete.
As shown in fig. 4, the upper baffle 27 includes an upper baffle main body section 271 extending up and down and an upper baffle bent section 272 bent and extending from a lower end of the upper baffle main body section 271 toward an outer peripheral surface of the casing 10 to constitute an upper passage 273 opened upward together with the outer peripheral surface of the casing 10. The lower baffle 28 includes a lower baffle body section 281 extending up and down and a lower baffle bending section 282 bending-extending from an upper end of the lower baffle body section 281 toward an outer circumferential surface of the casing 10 to constitute a lower passage 283 opening downward together with the outer circumferential surface of the casing 10. Further, the upper baffle bending section 272 and the lower baffle bending section 282 may each be arcuate to reduce airflow losses.
Fig. 7 is a schematic view illustrating the indoor unit of the vertical air conditioner shown in fig. 1 when switching to the maximum blowing mode; fig. 8 is a schematic cross-sectional view of the indoor unit of the stand air conditioner shown in fig. 7.
In some embodiments, the floor air conditioner indoor unit has a maximum blowing mode. Specifically, the shroud ring 20 is configured such that when it is in the up-blowing position, the upper baffle 27 is translatable upwardly away from the lower baffle 28, thereby allowing the supply air flow discharged from the air outlet 12 to be blown directly from the space between the upper and lower baffles 27, 28, see fig. 7 and 8. The air flow blowing-out process is smoother because the air flow is not interfered by the upper guide plate 27 and the lower guide plate 28, and the large air volume air outlet can be realized. Therefore, the embodiment of the invention can realize vertical upward air supply to enable the air to directly reach the roof, vertical downward air supply to enable the air flow to directly reach the ground, and the invention can also realize forward large-air-volume air supply like a conventional air conditioner, has diversified air supply modes and meets different requirements of users.
It will be appreciated that the lower baffle 28 may also be configured to translate up and down to achieve a maximum air out mode. Specifically, the shroud ring 20 is configured such that when in its down-blowing position, the lower baffle 28 is translatable downwardly away from the upper baffle 27, thereby allowing the supply air flow discharged from the outlet 12 to blow directly from the space between the upper and lower baffles 27, 28.
Fig. 9 is a schematic exploded view of the indoor unit of the stand air conditioner shown in fig. 1, and fig. 10 is an enlarged view at B of fig. 9.
As shown in fig. 9 and 10, the air outlet 12 is preferably elongated in the horizontal direction in the longitudinal direction. In this way, the lateral span of the air outlet 12 can be made larger, so that the lateral span of the contact surface between the air flow and the outer peripheral surface of the casing 10 is made larger, the air flow is more favorably attached to the outer peripheral surface of the casing 10, and the attaching effect is better.
As shown in fig. 9 and 10, a rack and pinion mechanism may be utilized to drive the translation of the cowl ring 20 up and down. Specifically, at least one motor 70 is installed on the casing 10, a gear 80 is installed on the motor 70, at least one rack 251 extending in the up-down direction is provided on the inner side of the air guiding cover ring 20, and each rack 251 is meshed with one gear 80, so that when the motor 70 drives the gear 80 to rotate, the rack 251 translates up and down to drive the air guiding cover ring 20 to translate up and down. Specifically, the number of the motors 70, the gears 80 and the racks 251 is two, and the two motors 70 are respectively installed at both lateral sides of the casing 10, so that the air guide cover ring 20 translates up and down more smoothly.
As shown in fig. 9 and 10, the air outlet 12 may be opened at the front side of the casing 10, so that the two lateral sides of the inner wall of the air guiding cover ring 20 are respectively provided with vertically extending wind shielding strips 25 for blocking the air flow of the air supply to flow backward, so that the air flow of the air supply only flows upward or downward along the outer peripheral surface of the front side part of the casing 10, and the air force is prevented from being influenced by the excessive dispersion of the air flow of the air supply. And, one rack 251 is formed on each weather strip 25. Namely, the rack 251 is arranged just by the wind shielding strip 25, and the structure is more ingenious.
The air guiding cover ring 20, the upper air guiding plate 27 and the lower air guiding plate 28 are connected to form a complete ring. In addition, the air guide cover ring 20, the upper air guide plate 27 and the lower air guide plate 28 may be connected in a semi-annular shape, so that the air guide cover ring can surround the circumferential section of the casing 10 where the air outlet 12 is formed, without completely surrounding the casing 10.
As shown in fig. 1 to 10, a wind guide swing blade 60 for guiding the supply air upward or downward may be installed at the air outlet 12. In this way, when the vertical air conditioner indoor unit operates in the upward blowing mode, the air guide swing blade 60 can be utilized to guide the air flow of the air supply upwards; in the down-blowing mode, the air-guiding swing blades 60 may be used to guide the air flow downward, so that the direction of the air flow is changed more gradually when the air flow is blown out from the air outlet 12 and then turned upward or downward, and the wind loss and noise are reduced. The wind-guiding swing blade 60 may be mounted on the frame 61, and the frame 61 is directly mounted on the air outlet 12.
