In particular, the present invention provides a vertical air conditioner indoor unit, comprising:
a casing, which is provided with an air outlet; and
the air guide cover ring is sleeved on the periphery of the shell to define an air guide channel with the peripheral surface of the shell, so that the air guide cover ring is used for guiding the air supply airflow flowing out of the air outlet to flow upwards and/or downwards along the peripheral surface of the shell; and is provided with
The air guide cover ring is configured to enable the distance between at least partial sections of the air guide cover ring and the outer peripheral surface of the shell to be adjustable so as to adjust the air output of the air guide channel.
Optionally, the wind deflector cover ring comprises: a body section mounted to the enclosure; and the adjusting section is opposite to the air outlet and movably arranged on the body section along the direction close to or far away from the outer peripheral surface of the machine shell so as to adjust the distance between the adjusting section and the outer peripheral surface of the machine shell.
Optionally, the indoor unit of an upright air conditioner further includes: the first gear rack mechanism is used for driving the adjusting section to translate along the direction close to or far away from the peripheral surface of the shell; and every first gear rack mechanism includes first motor, intermeshing's first gear and first rack, first motor install in body section, first gear set up in on the first motor, first rack set up in on the regulation section.
Optionally, the body section is mounted to the chassis in an up-down translational motion; and the wind guide cover ring is provided with a partition part protruding from the inner side surface of the wind guide cover ring to the outer peripheral surface of the shell so as to partition the wind guide channel into an upper channel with an upward opening and a lower channel with a downward opening, and the wind guide cover ring is configured in such a way that: the partition part can be moved to a position above the air outlet so as to guide the air supply flow downwards by the lower channel; or the air outlet is moved to a position where the separating part is positioned below the air outlet so as to guide the air flow upwards through the upper channel.
Optionally, the upper and lower surfaces of the partition are both concave cambered surfaces.

Optionally, the air outlet is arranged on the front side of the casing; the inner walls of the two transverse sides of the body section are respectively provided with a vertically extending wind shielding strip for blocking the backward flow of the air supply airflow; and each wind shielding strip is provided with one second rack.
Optionally, the air outlet is a long strip arranged along the horizontal direction in the length direction.
Optionally, an air guide swing vane for guiding the air supply flow upwards or downwards is mounted at the air outlet.
Optionally, the air outlet is located in an upper region of the front side of the casing, and an air inlet is formed in a lower portion of the rear side of the casing; and the vertical air conditioner indoor unit also comprises a centrifugal fan and a plate-shaped heat exchanger, wherein the centrifugal fan is arranged on the front side of the air inlet, the axis of the centrifugal fan extends along the front-back direction, and the plate-shaped heat exchanger is arranged in the upper area in the shell in a manner of gradually inclining forwards from top to bottom.
In the vertical air conditioner indoor unit, the casing is externally sleeved with the air guide cover ring, and the air guide cover ring and the outer peripheral surface of the casing define an air guide channel. After being blown out from the air outlet of the machine shell, the air flow (such as cold air or hot air) in the machine shell is blocked by the air guide cover ring, and cannot be directly blown out horizontally, but is blown out upwards and/or downwards along the outer periphery of the machine shell. Because the air supply flow flows tightly against the outer peripheral surface of the casing, a wall attachment effect is formed, and the air supply flow can smoothly reach the roof or the ground along the outer peripheral surface of the casing, so that the refrigerating or heating effect of the vertical air conditioner indoor unit is better. Meanwhile, the discomfort of the human body caused by cold air or hot air blowing can be avoided.
In the indoor unit of a floor air conditioner according to the present invention, the distance between at least a part of the section of the air guide cover ring and the outer circumferential surface of the casing is adjustable. When the distance is increased, the air outlet section of the air guide channel is enlarged, air is more smoothly discharged, and the air outlet quantity is larger; when the distance is adjusted to be small, the air outlet section of the air guide channel is reduced, and the air outlet quantity is reduced.
Furthermore, in the indoor unit of the vertical air conditioner, the air guide cover ring can be installed on the casing in a vertically-sliding mode, and the partition part divides the air guide channel into an upper channel with an upward opening and a lower channel with a downward opening, so that the indoor unit of the vertical air conditioner has an upper blowing mode and a lower blowing mode for selection, and the refrigeration and heating effects are improved. For example, when the air conditioning heat needs to operate the down-blowing mode, the air guide cover ring is moved to a position where the partition is located above the air outlet, and the air flow is guided downward by the lower channel. When the air conditioning needs to run in an upward blowing mode, the air guide cover ring is moved to a position where the separation part is positioned below the air outlet, and the air supply flow is guided upwards by the upper channel, so that the air conditioning is simple in structure and convenient to adjust.
Furthermore, in the vertical air conditioner indoor unit, the upper surface and the lower surface of the partition part are both concave cambered surfaces, and the air guide swing blade for guiding the air supply flow upwards or downwards is arranged at the air outlet, so that the direction change of the air supply flow is more moderate when the air supply flow is blown out from the air outlet and then turns upwards or downwards, and the wind power loss and the noise are reduced.

When a feature "comprises or comprises" a or some of its intended features, this is not to be taken as excluding the other features and other features may be further included, unless expressly stated otherwise.
The embodiment of the invention provides an indoor unit of a vertical air conditioner, which is used for conditioning indoor air, such as refrigeration, heating, dehumidification, fresh air introduction and the like.
Fig. 1 is a schematic view showing the construction of a vertical air conditioner indoor unit according to an embodiment of the present invention; fig. 2 is a schematic sectional view of the indoor unit of the floor type air conditioner shown in fig. 1; fig. 3 is a schematic view of the indoor unit of the floor air conditioner shown in fig. 1 after the air guide cover ring translation section moves forward; fig. 4 is a schematic sectional view of the indoor unit of an upright air conditioner shown in fig. 3. The flow direction of the supply air flow is indicated by arrows in the figure.
As shown in fig. 1 to 4, the indoor unit of a floor air conditioner according to an embodiment of the present invention may generally include a casing 10 and a wind guide cover ring 20.
The casing 10 is provided with an air outlet 12 for exhausting the air flow in the casing 10 to the indoor. The air supply airflow can be cold air produced by the vertical air conditioner indoor unit in a refrigeration mode, hot air produced in a heating mode, or fresh air introduced in a fresh air mode, and the like. The casing 10 is a vertically extending pillar structure, and the air outlet 12 may be disposed in an upper region of a front side of the casing 10, and referring to fig. 2, may also be disposed at other positions of the casing 10, such as a lower middle portion of the front side or a lateral side portion.
The wind guide cover ring 20 is fitted around the outer circumference of the casing 10 to define a wind guide passage 21 with the outer circumference of the casing 10. The air guide passage 21 is used to guide the air flow flowing out from the air outlet 12 to flow upward and/or downward along the outer circumferential surface of the casing 10. Specifically, after the air flow (for example, cold air or hot air) is blown out from the air outlet 12 of the casing 10, the air flow cannot be directly blown out horizontally by the inner wall of the air guide cover ring 20, and is blown out upward and/or downward along the outer circumferential surface of the casing 10. The upward and/or downward blowing here means: the blowing air flow can be blown out only upwards, or only downwards, or both upwards and downwards. The air stream flows in close contact with the outer peripheral surface of the casing 10, forming a coanda effect, which may also be referred to as a stick effect. Under the action of the wall attachment effect, the air supply flow can smoothly reach the roof or the ground along the peripheral surface of the casing 10, so that the cooling or heating effect of the vertical air conditioner indoor unit is better. Meanwhile, the discomfort of the human body caused by cold air or hot air blowing can be avoided.
Fig. 5 is a schematic view of the indoor stand air conditioner shown in fig. 2 when switched to the down-blowing mode. Fig. 1 and 2 illustrate a case where the indoor stand air conditioner operates in the up-blowing mode, and fig. 5 illustrates a case where the indoor stand air conditioner operates in the down-blowing mode.
As shown in fig. 1 and 2, when the indoor unit of a floor air conditioner operates in the up-blowing mode, the supply air flows upward while adhering to the outer peripheral surface of the casing 10. After reaching the top end, the airflow is scattered downwards to form a shower type air supply effect. As shown in fig. 5, when the indoor unit of the floor air conditioner operates in the down-blowing mode, the air flow is downward attached to the outer periphery of the casing 10, and then flows downward to the ground and then rises upward, thereby forming a carpet type air blowing effect. The outer peripheral surface area of the casing 10 through which the air flow flows can be made to be a flat surface, so that the air flow can better adhere to the outer peripheral surface of the casing 10 to flow.
The wind deflector cover ring 20 is a complete ring, i.e. a complete ring. Furthermore, the wind deflector cover ring 20 may be semi-annular, or minor arc, or nearly linear, so as to surround the circumferential section of the casing 10 where the wind outlet 12 is provided, without completely surrounding the casing 10.
The wind deflector shroud ring is further configured to: the distance (B in fig. 2 and 4) between at least a part of the segment of the wind guide cover ring 20 and the outer circumferential surface of the casing 10 is adjustable, so as to adjust the air output of the wind guide channel 21. Specifically, after the distance B is increased, the air outlet section of the air guide channel 21 is increased, so that the air outlet is smoother and the air outlet volume is larger; when the distance B is reduced, the air outlet section of the air guide passage 21 is reduced, and the air outlet amount is reduced. According to the embodiment of the invention, the air outlet quantity is adjusted by adjusting the air guide cover ring 20, and the air outlet quantity adjusting requirements of different use working conditions or scenes are met.
The distance B between at least a part of the section of the wind deflector cover ring 20 and the outer circumferential surface of the casing 10 is adjustable, which includes two cases. Specifically, the air guide cover ring 20 is formed as a whole, and the distance between the whole (entire section) of the air guide cover ring 20 and the outer peripheral surface of the casing 10 is adjustable. Alternatively, the wind deflector cover ring 20 may include a plurality of (two or more) segments that are joined together, and a part of (one or more) segments may be movable, so that the distance B between the segment and the outer circumferential surface of the casing 10 is adjustable.
For example, as shown in fig. 1-4, the air deflection shroud ring 20 may include a body segment 201 and an adjustment segment 202. The body section 201 is mounted to the cabinet 10. The adjusting section 202 is disposed opposite to the air outlet 12 and movably mounted to the body section 201 in a direction approaching or departing from the outer peripheral surface of the casing 10 so as to adjust a distance between the adjusting section and the outer peripheral surface of the casing 10. That is, the adjusting section 202 is the aforementioned "partial section" with adjustable distance from the outer peripheral surface of the housing 10.
Specifically, as shown in fig. 2 and fig. 4, the air outlet 12 is opened at the front side of the casing 10, the adjusting section 202 is disposed in front of the air outlet 12, and the body section 201 is mounted on the body section 201 movably in the front-and-back direction. The front side of the main body section 201 has a gap, which is opposite to the air outlet 12 and is used for accommodating the adjusting section 202. The edge shape of the adjustment section 202 matches the shape of the gap of the body section 201 (e.g., both are rectangular) so as to adjust to a fitted position just "fitting" at the gap, as in fig. 1, to make the appearance of the indoor unit of the floor air conditioner more beautiful. When the air conditioner is in the off state, the adjusting section 202 can be in the engaging position.
In some embodiments, as shown in fig. 2 and 5, the body section 201 of the wind deflector shroud ring 20 can be mounted to the casing 10 to be movable in translation up and down. It will be appreciated that as the body section 201 translates up and down, the adjustment section 202 will also translate up and down with the body section 201. The air guide shroud ring 20 has a partition 23 projecting from the inner surface thereof toward the outer peripheral surface of the casing 10. The partition 23 is used to partition the air guide passage 21 into an upper passage 212 opening upward and a lower passage 214 opening downward. The wind deflector shroud ring 20 is configured to: the partition 23 can be moved to a position above the outlet 12 to guide the air flow downward from the lower channel 214, as shown in fig. 5; or moved to a position where the partition 23 is located below the outlet 12, so that the air flow is guided upward by the upper duct 212, as shown in fig. 2.
Therefore, the vertical air conditioner indoor unit has an upward blowing mode and a downward blowing mode for a system or a user to select, so that the refrigeration and heating effects are obviously improved. For example, when the air conditioning heat requires the down-blowing mode, the air guide cover ring 20 is moved to a position where the partition 23 is located above the air outlet 12, and the air flow is guided downward by the lower duct 214, as shown in fig. 5. When the air conditioner cooling needs to operate the upward blowing mode, the air guide cover ring 20 is moved to a position where the partition 23 is located below the air outlet 12, and the air flow is guided upward by the upper duct 212, as shown in fig. 2.
Of course, the hood ring 20 may be moved to a position between the upper blow mode and the lower blow mode such that a portion of the flow of supply air exiting the air outlet 12 is directed upwardly from the upper duct 212 and another portion is directed downwardly from the lower duct 214 for simultaneous upward and downward supply.
As shown in fig. 2, the upper and lower surfaces of the partition 23 may be both concave curved surfaces, so that when the blowing air flow is blown out from the outlet 12 and then turned upward or downward, the change in direction is more gradual, and wind loss and noise are reduced.
FIG. 6 is an enlarged cross-sectional view of N-N of FIG. 2; fig. 7 is a schematic exploded view of the indoor unit of a floor type air conditioner shown in fig. 1.
As shown in fig. 6 and 7, the outlet 12 may be formed in a long strip shape whose length direction is along the horizontal direction. Therefore, the transverse span of the air outlet 12 can be made larger, which is beneficial to designing the air guiding channel 21 into a flat shape with smaller width (the distance B between the air guiding cover ring 20 and the outer peripheral surface of the casing 10) and longer length (namely, the dimension of the air guiding channel 21 along the circumferential direction of the casing 10), so as to be beneficial to attaching the air flow to the outer peripheral surface of the casing 10 more, and make the attaching effect better. Moreover, the air guide cover ring 20 is closer to the casing 10, so that the vertical air conditioner indoor unit is prevented from being thicker due to the arrangement of the air guide cover ring 20, and the packaging and the appearance are prevented from being influenced. As shown in fig. 4, the ratio of the width of the air guiding channel 21 to the height of the air outlet 12 (the dimension of the air outlet 12 in the vertical direction) is further set to be 1/4 to 1/3, for example, 0.3, so as to obtain the optimal attaching effect.
Fig. 8 is an enlarged view of fig. 7 at a, and fig. 9 is an enlarged view of fig. 7 at D.
As shown in fig. 6, 7 and 9, the indoor unit of the floor air conditioner includes at least one first rack and pinion mechanism for driving the adjusting section 202 to translate in a direction approaching or departing from the outer circumferential surface of the casing 10. Each first rack-and-pinion mechanism includes a first motor 71, a first gear 81 and a first rack 26 engaged with each other, the first motor 71 is mounted on the body section 201, the first gear 81 is disposed on the first motor 71, and the first rack 26 is disposed on the adjusting section 202. When the first motor 71 drives the first gear 81 to rotate, the first rack 26 is made to translate to drive the adjusting section 202 to translate. Specifically, the number of the first rack and pinion mechanisms is preferably one, and the first motors 71 are respectively mounted on one lateral side of the body section 201 at the notch. In addition, two sliding rails 282 are respectively arranged at two lateral sides of the notch of the body section 201, two lateral ends of the adjusting section 202 respectively form a positioning protrusion 281, and each positioning protrusion 281 is slidably installed in one sliding rail 282 to guide the translational movement of the adjusting section 202. The first rack 26 may be formed on one of the positioning protrusions 281.
