Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and particularly to a vertical air conditioner indoor unit and its air guiding device. Background Art

[0002] Currently, common vertical air conditioner indoor units are usually provided with vertical strip-shaped air outlets for blowing the air supply airflow into the indoor environment to adjust the indoor environmental air. Generally, vertical air conditioner indoor units use vertical vanes to guide the left and right air outlet angles or perform left and right swinging of the air. This kind of air guiding structure is widely used in the air conditioning field and lacks innovation.

[0003] In addition, although the vertical vanes change the left and right air outlet directions, when a user passes in front of the air conditioner, they will still be blown by cold or hot air and feel obvious heat or cold, and the user experience is not particularly good. Summary of the Invention

[0004] An object of the present invention is to provide an air guiding device for a vertical air conditioner indoor unit that enables the air supply airflow to avoid the human body.

[0005] A further object of the present invention is to simplify the structure of the air guiding device.

[0006] Another object of the present invention is to provide a vertical air conditioner indoor unit using the above air guiding device.

[0007] On the one hand, the present invention provides an air guiding device for a vertical air conditioner indoor unit, which is rotatably mounted around a vertical axis at the air outlet of the housing of the vertical air conditioner indoor unit to block or open the air outlet, and is used to guide the lateral air outlet direction of the air outlet when in the open position;

[0008] The air guiding device includes a plurality of air guiding cylinders. When the air guiding device is in the closed position of blocking the air outlet, the air inlet ends of the air guiding cylinders face the inside of the air outlet to allow the air guiding cylinders to guide the airflow direction.

[0009] Optionally, when the air guiding device is in the closed position, the air guiding cylinders gradually extend upwardly and obliquely from the air inlet end to the air outlet end.

[0010] Optionally, at least part of the circumferential wall of the air guiding cylinders is provided with upwardly facing notches.

[0011] Optionally, the plurality of air guiding cylinders are arranged in multiple columns, and the air guiding cylinders in each column are arranged at intervals in the vertical direction in sequence.

[0012] Optionally, the air guiding device further includes a vertical rod, which is rotatably mounted around the vertical axis on the housing, and the air guiding cylinders are formed on or fixed to the vertical rod.

[0013] Optionally, multiple air guide cylinders are arranged in three columns;

[0014] The air guide cylinders in the middle column are formed on the vertical rod, and their inner holes penetrate the vertical rod;

[0015] The other two columns of air guide cylinders are respectively located on both sides of the vertical rod and fixed to the vertical rod.

[0016] Optionally, each of the air guide cylinders located on both sides of the vertical rod respectively has a connecting arm, and the connecting arm is connected to the vertical rod.

[0017] Optionally, multiple air guide cylinders are arranged in a matrix.

[0018] On the other hand, the present invention also provides a vertical air conditioner indoor unit, which includes:

[0019] A housing that is provided with at least one air outlet; and

[0020] At least one air guide device as described in any one of the above, and each air guide device is rotatably installed at one of the air outlets around a vertical axis.

[0021] Optionally, each air outlet is matched with multiple air guide devices, and the multiple air guide devices are arranged at intervals along the width direction of the air outlet.

[0022] The air guide device of the present invention has a closed position and an open position. When in the open position, the overall air guide device guides the lateral air outlet direction, including performing lateral air swing, and the air volume is relatively large. When the air guide device is in the blocking position, the air guide cylinder guides the air flow direction. Its air outlet direction can be designed so that the air flow is guided to an angle where it does not blow on people (for example, the air guide cylinder can be tilted upward to guide the air flow forward and upward), so that the cold air / hot air avoids the human body, and the air flow is separated and dispersed by the air guide cylinder, making the air flow softer and improving the user experience.

[0023] Furthermore, in the air guide device of the present invention, the air guide cylinders in the middle column are formed on the vertical rod, and their inner holes penetrate the vertical rod. The other two columns of air guide cylinders are respectively located on both sides of the vertical rod and fixed to the vertical rod. This solution makes full use of the vertical rod, enabling more air guide cylinders, a greater density, and a stronger guiding force for the air flow.

Those of ordinary skill in the art should be able to understand the specific meanings of the above terms in the present invention according to specific circumstances.

[0034] The present invention provides a vertical air conditioner indoor unit and its air guiding device 20. Among them, the vertical air conditioner indoor unit is the indoor part of a split vertical air conditioner, which is used to adjust indoor air, such as refrigeration / heating, dehumidification, introducing fresh air, etc. The air guiding device 20 is applied to the vertical air conditioner indoor unit and is used to adjust the air outlet direction at the air outlet 12.

[0035] Figure 1 is a schematic front view of a vertical air conditioner indoor unit according to an embodiment of the present invention; Figure 2 is Figure 1 a schematic top view of the upper structure of the air outlet 12 in the shown vertical air conditioner indoor unit; Figure 3 is Figure 2 a schematic view of the shown structure when each air guiding device 20 is in the open position; Figure 4 is a schematic structural view of the air guiding device 20 according to an embodiment of the present invention; Figure 5 is Figure 4 a schematic view of another perspective of the shown air guiding device 20. Figure 4 and Figure 5 schematically show the wind direction with arrows.

[0036] As Figures 1 to 3 shown, the air guiding device 20 of the embodiment of the present invention is rotatably installed at the air outlet 12 of the housing 10 of the vertical air conditioner indoor unit around the vertical axes y1, y2, y3, so as to block or open the air outlet 12, and when in the open position, it is used to guide the lateral air outlet direction of the air outlet 12, that is, the left - right air outlet direction, for example, blowing the air flow towards the left front, right front, and directly in front. When the air guiding device 20 reciprocally rotates, left - right swinging of the air can be realized.

[0037] For example Figure 1 and Figure 2 show the state when the air guiding device 20 is in the closed position. For clear illustration, Figure 1 and Figure 2 the air guiding device 20 in Figure 3 is shown in a simplified box form to show the state when the air guiding device 20 conducts air guiding, and the air flow will flow out from the spaced - apart space between adjacent air guiding devices 20. The shape of the air guiding device 20 can match the shape of the air outlet 12. For exampleFigure 2 , since the air outlet 12 is strip-shaped, the air guiding device 20 is strip-shaped.

[0038] Please refer to Figure 2 , Figure 4 and Figure 5 , the air guiding device 20 of the embodiment of the present invention includes a plurality of air guiding cylinders 22, 23. When the air guiding device 20 is in the closed position of blocking the air outlet 12 (such as Figure 2 ), the air inlet ends A of the air guiding cylinders 22, 23 face the inside of the air outlet 12 to allow the air guiding cylinders 22, 23 to guide the air flow direction. That is, the air flow inside the housing 10 enters the inside of the air guiding cylinders 22, 23 through the air inlet ends A, and then flows outwards from the air outlet ends B.

[0039] The air guiding device 20 of the embodiment of the present invention has a closed position and an open position. When in the open position, the overall air guiding device 20 (which can be regarded as a deflector) guides the horizontal air outlet direction, including performing horizontal air swing, and the air volume is relatively large, such as Figure 3 . When the air guiding device 20 is in the blocking position, such as Figure 2 , the air guiding cylinders 22, 23 guide the air flow direction, and its air outlet direction can be designed so that the air flow is guided to an angle that does not blow on people (for example, the air guiding cylinders 22, 23 can be tilted upwards to guide the air flow forward and upwards), so that the cold air / hot air avoids the human body, and the air flow is separated and dispersed by the air guiding cylinders 22, 23, making the air flow softer and improving the user experience.

[0040] The air guiding device 20 of the embodiment of the present invention has the function of guiding air left and right. In this way, the air guiding device 20 can not only guide air left and right by rotating, but also realize upward guiding through the air guiding cylinders 22, 23, achieving a two-in-one effect. Therefore, the swing blades for guiding air up and down can be omitted, simplifying the structure of the indoor unit of the floor-standing air conditioner.

[0041] In some embodiments, as shown in Figure 4 and Figure 5 , when the air guiding device 20 is in the closed position, the air guiding cylinders 22, 23 gradually extend upwards and obliquely from the air inlet end A to the air outlet end B to guide the air flow forward and upwards, so that the cold air / hot air fully avoids the human body. The elevation angle of each air guiding cylinder 22, 23 (that is, the angle between the air guiding cylinder 22, 23 and the horizontal plane) is between 40° and 45°, so as to guide the air flow upwards at an elevation angle of 40° to 45°. Through experiments, when the elevation angle is designed between 40° and 45°, users can obtain a better air feeling experience.

[0042] Furthermore, as shown in Figure 4 and Figure 5As shown, at least part of the peripheral wall of the air guide cylinder 22 is provided with an upward notch to form a "U" - shaped structure, so that the air flow can enter the air guide cylinder 22 from above, avoiding the situation that the air flow can only enter the air guide cylinder 22 from the end of the air guide cylinder 22, resulting in too little air intake volume.

[0043] In some embodiments, a plurality of air guide cylinders 22, 23 can be arranged in multiple columns, and the arrangement direction X of each column constitutes the width direction of the air guide device 20. Each air guide cylinder 22, 23 in each column is arranged at intervals in the vertical direction in sequence. Preferably, a plurality of air guide cylinders 22, 23 are arranged in a matrix to make its appearance more regular and beautiful. Of course, in some alternative embodiments, the air guide cylinders 22, 23 in adjacent two columns can also be arranged with alternating heights, or arranged in a disordered manner.

[0044] In some embodiments, as Figure 4 and Figure 5 shown, the air guide device 20 further includes a vertical rod 21. The vertical rod 21 is rotatably mounted on the housing 10 around a vertical axis, and the air guide cylinder is formed on or fixed to the vertical rod 21. The so - called "fixed to the vertical rod 21" can be directly fixed to the vertical rod 21 or indirectly fixed to the vertical rod 21 through other structures.

[0045] For example Figure 4 and Figure 5 shown, a plurality of air guide cylinders 22, 23 can be arranged in three columns in total. Among them, the air guide cylinders 23 in the middle column are formed on the vertical rod 21, and the inner holes thereof penetrate the vertical rod 21. The other two columns of air guide cylinders 22 are respectively located on both sides of the vertical rod 21 and fixed to the vertical rod 21. For example, each air guide cylinder 22 located on both sides of the vertical rod 21 respectively has a connecting arm 225, and the connecting arm 225 is connected to the vertical rod 21. Referring to Figure 2 and Figure 5 , each air guide cylinder 22 has three connecting arms 225.

[0046] On the other hand, the present invention also provides a vertical air conditioner indoor unit. The vertical air conditioner indoor unit is the indoor part of an air - conditioning device that can use a vapor compression refrigeration cycle system or other refrigeration systems for refrigeration / heating, and the specific principle will not be elaborated here.

[0047] Generally, the vertical air conditioner indoor unit can include a housing 10 and at least one air guide device 20 as described in any of the above embodiments.

[0048] The housing 10 defines a cavity for accommodating the main structure of the vertical air conditioner indoor unit, such as an evaporator, a blower, etc. The housing 10 includes a panel 14 for constituting the appearance of the vertical air conditioner indoor unit, and also includes a skeleton (not shown) covered by the panel 14 for carrying the air - conditioning structure.

[0049] The housing 10 is provided with an air inlet (not shown, but may be provided at the rear side or both lateral sides of the housing 10) and at least one air outlet 12. Figures 1 to 3 As shown, the housing 10 may be provided with two air outlets 12. The air inlet is used to introduce indoor air, and the indoor air forms a heat exchange airflow after completing heat exchange with the evaporator in the housing 10, and then flows to the air outlet 12 under the action of the fan. The air outlet 12 is used to blow the conditioned airflow (heat exchange airflow, purified airflow or fresh airflow, etc.) in the housing 10 to the indoor environment to regulate the indoor ambient air.

[0050] Each air guiding device 20 is rotatably installed at an air outlet 12 around a vertical axis to guide the air outlet direction of the air outlet 12 .

[0051] In some embodiments, each air outlet 12 is matched with a plurality of air guide devices 20, and the plurality of air guide devices 20 are arranged at intervals along the width direction (x direction) of the air outlet 12. Figure 2 and Figure 3 As shown, each air outlet 12 is matched with three air guide devices 20. The plurality of air guide devices 20 can be rotated to a closed position, such as Figure 2 ; It can also be turned to the open position to guide the wind, such as Figure 3 For the same air outlet width, multiple air guide devices 20 are provided, which can reduce the width of each air guide device 20 and prevent the rotation of the air guide device 20 from interfering with the internal structure of the housing 10 .

[0052] In some embodiments, each connecting rod of the connecting rod mechanism can be connected to each air guide device 20, so that a plurality of air guide devices 20 can be driven to rotate in conjunction with each other by one motor.

[0053] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
