Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] It should be noted that the terminology used herein is for the purpose of describing particular implementations only and is not intended to limit the exemplary implementations according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0044] Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof; the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that an article or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such an article or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the article or system that includes said element.

[0045] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0046] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0047] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0049] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components, and does not imply any sequential order; unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0050] This invention relates to the field of air conditioners, specifically to a vertical air conditioner indoor unit and an air conditioner.

[0051] Currently, people have increasingly higher requirements for the comfort of air conditioners, and their requirements for noise reduction are also increasing accordingly. Centrifugal fans have advantages such as strong air delivery capacity and long distance. However, centrifugal fans have relatively high air delivery noise, which has a certain impact on indoor users and is not conducive to user experience.

[0052] Currently, competing products offer features such as windless operation and multi-circulation airflow to achieve diversified air supply, and the air volume is also increased accordingly; however, the air supply mode of vertical air conditioners is relatively simple, which is not conducive to adapting to different indoor needs.

[0053] To improve the air supply diversity of floor-standing air conditioners, such as Figure 1-12 As shown, a vertical air conditioner indoor unit and air conditioner are proposed.

[0054] like Figure 1-5 As shown, the present invention proposes a vertical air conditioner indoor unit, including a cylindrical inner shell 3 and a cylindrical outer shell 4 sleeved outside the inner shell 3. The outer shell 4 is provided with an air outlet, the length direction of which is vertical. The inner shell 3 includes a protrusion 5, which is located inside the air outlet and divides the air outlet into a first air outlet 101 and a second air outlet 201 in the circumferential direction of the outer shell 4.

[0055] A first air guide plate A1011 is hinged to the first air outlet 101, and / or a second air guide plate A2011 is hinged to the second air outlet 201.

[0056] In actual use, the air outlet of the outer shell 4 faces the indoor activity space. By making a part of the inner shell 3 protrude at the air outlet, the air outlet is divided into two air outlets, which simplifies the structural components of the air outlet.

[0057] The air outlet is divided into a first air outlet 101 and a second air outlet 201. The arrangement of the first air guide plate A1011 and the second air guide plate A2011 can change the air outlet pattern, enabling the indoor unit to achieve both concentrated and wide-angle airflow. Specifically, as... Figure 5 As shown, when the first air guide plate A1011 rotates, a flared structure is formed between the first air guide plate A1011 and the outer wall of the inner shell 3, allowing the gas discharged from the first outlet 101 to flow over a wider range, forming a wide-angle air supply. Figure 2 As shown, when the first air guide plate A1011 rotates, reducing the expansion of the flared structure between the first air guide plate A1011 and the outer wall of the inner casing 3, or forming a structure of basically equal width (the width between the first air guide plate and the inner casing 3 is basically consistent along the direction of gas flow), or even forming a constricted structure, the gas discharged from the first outlet vent 101 is delivered to a relatively small area at a higher speed, forming concentrated air supply. Similarly, controlling the rotation of the second air guide plate A2011 achieves the same effect as the first air guide plate A1011. The rotation of the first air guide plate A1011 and the second air guide plate A2011 enables wide-angle and concentrated air supply for the vertical indoor unit, improving its applicability. That is, as... Figure 4 As shown, the first air outlet 101 and the second air outlet 201 can either provide concentrated airflow and wide-angle airflow, or both can provide wide-angle airflow simultaneously or concentrated airflow simultaneously. When both air guide vanes swing towards one side of the inner casing 3 and come into contact with the inner casing 3, the first air outlet 101 and the second air outlet 201 close to prevent external insects from entering. Because the indoor unit of the air conditioner is a vertical unit, whether it is concentrated airflow or wide-angle airflow, the air can always be delivered from high to low within a certain horizontal area of ​​the room, so that users in the airflow area can always feel the required airflow.

[0058] Preferred, such as Figure 6-12 As shown, the end of the outer casing 4 closest to the first outlet air vent 101 is the first end of the outer casing 4, and the end of the outer casing 4 closest to the second outlet air vent 201 is the second end of the outer casing 4.

[0059] A first air guide plate B1012 is also hinged to the first air outlet 101. The hinge end of the first air guide plate A1011 is close to the first end of the outer shell 4, and the hinge end of the first air guide plate B1012 is away from the first end of the outer shell 4.

[0060] And / or,

[0061] A second air guide plate B2012 is also hinged at the second air outlet 201. The hinge end of the second air guide plate A2011 is close to the second end of the outer shell 4, and the hinge end of the second air guide plate B2012 is away from the second end of the outer shell 4.

[0062] The gas discharged from the first outlet 101 is guided by the first guide vane A1011 and the first guide vane B, thereby causing the gas discharged from the first outlet 101 to flow in different directions and changing the gas flow speed. Compared with only the first guide vane A1011, the control of gas flow direction and speed is more precise.

[0063] Similarly, the second guide vane A2011 and the second guide vane B guide the gas discharged from the second outlet 201, causing the gas discharged from the second outlet 201 to flow in different directions and changing the gas flow speed. Compared with only setting the second guide vane A2011, the control of gas flow direction and speed is more precise.

[0064] The first air guide plate A1011 is hinged at one end and oscillating at the other end; similarly, the first air guide plate B1012 is hinged at one end and oscillating at the other end, with the oscillating end of the first air guide plate B1012 located between the hinged end of the first air guide plate A1011 and the inner shell 3.

[0065] The second air guide plate A2011 is hinged at one end and oscillating at the other end; the second air guide plate B2012 is hinged at one end and oscillating at the other end, and the oscillating end of the second air guide plate B2012 is located between the hinged end of the second air guide plate A2011 and the inner shell 3.

[0066] The swing end of the first air guide plate B1012 swings towards the inner housing 3 and abuts against the inner housing 3, while the swing end of the first air guide plate A1011 swings away from the inner housing 3, thus forming a first air supply channel A1101 between the first air guide plate A1011 and the first air guide plate B1012. Figure 8As shown, all the gas discharged from the first outlet vent 101 flows out through the first air supply channel A1101. Similarly, the swing end of the second guide plate B2012 swings towards the inner shell 3 and abuts against the inner shell 3, while the swing end of the second guide plate A2011 swings away from the inner shell 3, forming a second air supply channel A1102 between the second guide plate A2011 and the second guide plate B2012. All the gas discharged from the second outlet vent 201 flows out through the second air supply channel A1102. This creates a windless area between the first outlet vent 101 and the second outlet vent 201, improving the diversity of indoor air supply; moreover, air supply through the first air supply channel A1101 and the second air supply channel A1102 increases the concentration of gas and improves the effect of centralized air supply.

[0067] Of course, when the swing ends of the first air guide plate B1012 and the second air guide plate B2012 are separated from the inner shell 3, the gas discharged from the first air outlet 101 and the second air outlet 201 will be discharged through the gap between the first air guide plate B1012 and the inner shell 3. This allows the area between the first air guide plate B1012 and the second air guide plate B2012 to also be ventilated, and the gas in this area is weaker than the gas flowing out of the first air supply channel A1101 and the second air supply channel B1202. This improves the gas state in different areas of the room and further improves the applicability of the indoor unit.

[0068] Preferably, the rotation of the first air guide plate A1011 and the first air guide plate B1012 can cause the first air guide plate A1011 and the first air guide plate B1012 to at least partially overlap.

[0069] And / or,

[0070] The rotation of the second air guide plate A2011 and the second air guide plate B2012 can cause the second air guide plate A2011 and the second air guide plate B2012 to at least partially overlap.

[0071] Example 1, as Figure 6-7 As shown:

[0072] The swing end of the first air guide plate B1012 swings away from the inner shell 3, and the swing end of the first air guide plate A1011 swings towards the inner shell 3, thereby making the first air guide plate A1011 and the first air guide plate B1012 at least partially overlap. This improves the rigidity of the first air guide plate A1011 and the first air guide plate B1012 as a whole, and improves the guiding effect on the gas discharged from the first outlet vent 101. It avoids the phenomenon of vibration that is easy to occur when only one air guide plate A is set, and further reduces noise.

[0073] Similarly, the swing end of the second air guide plate B2012 swings away from the inner shell 3, while the swing end of the second air guide plate A2011 swings towards the inner shell 3, thereby causing the second air guide plate A2011 and the second air guide plate B2012 to at least partially overlap. This improves the rigidity of the second air guide plate A2011 and the second air guide plate B2012 as a whole, enhances the guiding effect on the gas discharged from the second outlet 201, avoids the vibration phenomenon that is easy to occur when only two air guide plates A are set, and further reduces noise.

[0074] When the vertical indoor unit is turned off, the swing end of the first air guide plate B1012 swings towards the inner casing 3 and abuts against the inner casing 3, and the swing end of the first air guide plate A1011 also swings towards the casing and abuts against the first air guide plate B1012, which is equivalent to closing the first air supply channel A1101. This prevents external dust, flying insects, etc. from entering the interior of the indoor unit through the first air outlet 101 when the unit is off.

[0075] Similarly, such as Figure 7 As shown, when the vertical indoor unit is turned off, the swing end of the second air guide plate B2012 swings towards the inner casing 3 and abuts against the inner casing 3, and the swing end of the second air guide plate A2011 also swings towards the casing and abuts against the second air guide plate B2012, which is equivalent to closing the second air supply channel A1102. This prevents external dust, flying insects, etc. from entering the interior of the indoor unit through the second air outlet 201 when the unit is off.

[0076] Preferably, the first air guide plate A1011 and the first air guide plate B1012 can be rotated to make the first air guide plate A1011 and the first air guide plate B1012 flush.

[0077] And / or,

[0078] The second air guide plate A2011 and the second air guide plate B2012 can rotate to make the second air guide plate A2011 and the second air guide plate B2012 flush.

[0079] Here, "aligned" means that the surface of the first air guide plate A1011 facing the inner shell 3 and the surface of the first air guide plate B1012 facing the inner shell 3 are in the same plane.

[0080] Similarly, the surface of the second air guide plate A2011 facing the inner shell 3 and the surface of the second air guide plate B2012 facing the inner shell 3 are in the same plane.

[0081] Example 2, as Figure 9-12 As shown:

[0082] The swing end of the first air guide plate B1012 swings away from the inner shell 3, and the swing end of the first air guide plate A1011 swings towards the inner shell 3, thereby making the first air guide plate A1011 and the first air guide plate B1012 flush. The first air guide plate A1011 and the first air guide plate B1012 in the flush state form a first air supply channel B1201 with the inner shell 3. Compared with the first embodiment, since the first air guide plate A1011 and the first air guide plate B1012 do not need to overlap, the air supply area of ​​the first air supply channel B1201 is larger than the flow area between the first air guide plate B1012 and the inner shell 3 in the first embodiment. In this way, while ensuring the same air supply direction, the resistance to the gas is reduced and the gas flow rate is guaranteed.

[0083] Similarly, the swing end of the second air guide plate B2012 swings away from the inner shell 3, and the swing end of the second air guide plate A2011 swings towards the inner shell 3, thereby making the second air guide plate A2011 and the second air guide plate B2012 flush. The flush second air guide plate A2011 and the second air guide plate B2012 form a second air supply channel B1202 between the inner shell 3. Compared with the first embodiment, since the second air guide plate A2011 and the second air guide plate B2012 do not need to overlap, the air supply area of ​​the second air supply channel B1202 is larger than the flow area between the second air guide plate B2012 and the inner shell 3 in the first embodiment. In this way, while ensuring the same air supply direction, the resistance to the gas is reduced, and the gas flow rate is guaranteed.

[0084] like Figure 10 and 12 As shown, when the vertical indoor unit is turned off, the swing end of the first air guide plate A1011 swings towards the inner casing 3 and abuts against the inner casing 3, which is equivalent to closing the first air supply channel B1201. This prevents external dust, flying insects, etc. from entering the interior of the indoor unit through the first air outlet 101 when the unit is off.

[0085] Similarly, the swing end of the second air guide plate A2011 swings towards the inner casing 3 and abuts against the inner casing 3, which is equivalent to closing the second air supply channel B1202. This prevents external dust, flying insects, etc. from entering the interior of the indoor unit through the second air outlet 201 when the unit is stopped.

[0086] When the first air guide plate A1011 and the first air guide plate B1012 are flush, they can either just touch or form a gap. When a gap is formed, air can flow out from within it, increasing the airflow area and improving the usability of the indoor unit. Similarly, when the second air guide plate A2011 and the second air guide plate B2012 are flush, they can either just touch or form a gap. When a gap is formed, air can flow out from within it, increasing the airflow area and improving the usability of the indoor unit.

[0087] Example 3: When the first air guide plate A1011 and the first air guide plate B1012 are flush, a gap is formed between the two air guide plates. When gas flows through the first air supply channel B1201, some gas flows out from this gap to cool or heat other areas. When the second air guide plate A2011 and the second air guide plate B2012 are flush, a gap is formed between the two air guide plates. When gas flows through the second air supply channel B1202, some gas flows out from this gap to cool or heat other areas.

[0088] Similarly, the surface of the second air guide plate A2011 facing the inner shell 3 and the surface of the second air guide plate B2012 facing the inner shell 3 are in the same plane.

[0089] Preferably, the first air guide plate B1012 is provided with a plurality of first air vents, and / or the second air guide plate B2012 is provided with a plurality of second air vents.

[0090] The first and second vents are small-diameter holes, allowing only a small amount of gas to flow through. When the gas discharged from the first outlet 101 flows through the first guide plate B1012, some of the gas passes through the first vent and is discharged. The gas velocity and flow rate through the first vent are both low, resulting in gentle airflow.

[0091] Similarly, when the gas discharged from the second outlet 201 flows through the second air guide plate B2012, some of the gas passes through the second vent and is discharged. The gas velocity and flow rate through the second vent are both relatively small, forming a gentle airflow.

[0092] This further improves the applicability of the air conditioner indoor unit.

[0093] Preferred, such as Figure 2-12 As shown, a fan assembly is provided inside the inner shell 3. The fan assembly includes a first inner air outlet 1301 and a second inner air outlet 1302. The first inner air outlet 1301 and the first outer air outlet 101 are connected through a first air outlet channel 1. The second inner air outlet 1302 and the second outer air outlet 201 are connected through a second air outlet channel 2.

[0094] In existing technology, the air outlet of the fan assembly faces directly towards the indoor activity area, and the noise generated by the fan assembly is directly transmitted into the room through the air outlet. In this application, the first inner air outlet 1301 and the second inner air outlet 1302 of the fan assembly no longer face directly into the room. Instead, they are connected to the first outer air outlet 101 and the second outer air outlet 201 through the first air outlet channel 1 and the second air outlet channel 2. This allows the gas discharged from the first inner air outlet 1301 and the second inner air outlet 1302 to first pass through the first air outlet channel 1 and the second air outlet channel 2 before being discharged into the indoor space. The noise generated when the gas is discharged from the first inner air outlet 1301 gradually weakens within the first air outlet channel 1, thereby reducing the impact of indoor unit noise on indoor users. Simultaneously, the first air outlet channel 1 rectifies the gas flow, improving the directionality of the gas flow and helping to increase the travel distance of the gas after it exits the indoor unit.

[0095] Similarly, the noise generated when the gas is discharged from the second internal air outlet 1302 gradually decreases in the second air outlet channel 2, thereby reducing the impact of the noise inside the indoor unit on the indoor users. At the same time, the second air outlet channel 2 rectifies the gas, improves the directionality of the gas flow, and helps to increase the flow distance of the gas after it is discharged from the indoor unit.

[0096] The first air outlet duct 1 and the second air outlet duct 2 constitute a noise reduction duct and a rectification duct.

[0097] Preferably, the first air outlet channel 1 and the second air outlet channel 2 are symmetrically arranged, and / or the first air outlet channel 1 and the second air outlet channel 2 are independently arranged.

[0098] The first air outlet duct 1 and the second air outlet duct 2 are symmetrically arranged, so that the distance between the first internal air outlet 1301 and the first external air outlet 101 is the same as the distance between the bracket of the second internal air outlet 1302 and the second external air outlet 201. This ensures that the air flows the same distance in both air outlet ducts, which helps to make the noise reduction and rectification effects of the two air outlet ducts the same or similar, thus improving the user experience. In addition, the symmetrical arrangement of the two air outlet ducts also balances the force on the indoor unit of the air conditioner, reducing the noise caused by asymmetry. At the same time, the symmetrical arrangement also allows the vertical air conditioner indoor unit to be installed more evenly in the room.

[0099] The first air outlet duct 1 and the second air outlet duct 2 are set independently to avoid pressure loss caused by mutual disturbance of the gas discharged from the first internal air outlet 1301 and the second internal air outlet 1302; at the same time, it also avoids noise generated by mutual disturbance of the gas.

[0100] Preferably, (no schematic diagram) the first internal air outlet 1301 and the second internal air outlet 1302 are oriented far apart from each other.

[0101] "Back-to-back arrangement" means that the flow direction of gas when it is discharged from the first internal air outlet 1301 is opposite to the flow direction of gas when it is discharged from the second internal air outlet 1302.

[0102] By arranging the first internal air outlet 1301 and the second internal air outlet 1302 back to back, the forces inside the indoor unit are balanced, which helps to reduce noise.

[0103] Preferred, such as Figure 2-12 As shown, the orientation of the first internal air outlet 1301 is opposite to the orientation of the first external air outlet 101, and / or, the orientation of the second internal air outlet 1302 is opposite to the orientation of the second external air outlet 201.

[0104] In this way, the length of the first air outlet duct 1 is extended to the maximum extent, and the noise reduction and rectification effect of the first air duct on the gas is improved.

[0105] Similarly, the length of the second air outlet duct 2 has been extended to the maximum extent, which improves the noise reduction and rectification effect of the second air duct on the gas.

[0106] Considering practical usage, the first and second outdoor air vents 101 and 201 of the vertical air conditioner indoor unit face the indoor activity area, while the first and second indoor air vents 1301 and 1302 face away from the indoor activity area. Therefore, the initial direction of noise propagating outward from the first and second indoor air vents 1301 and 1302 is also away from the indoor activity area, further reducing the impact of noise on indoor users. Simultaneously, the orientation of the first indoor air vent 1301 is opposite to that of the first outdoor air vent 101, and the orientation of the second indoor air vent 1302 is opposite to that of the second outdoor air vent 201, maximizing the length of the first and second air ducts 1 and 2, which helps improve the noise reduction effect. Moreover, this arrangement allows the first and second air ducts 1 and 2 to encircle the inner casing 3, forming a sound insulation cavity, which has a certain sound insulation effect on noise generated inside the inner casing 3. Preferably, as... Figure 1 As shown, the inner housing 3 is provided with a first volute 701 and a first centrifugal fan 601 located inside the first volute 701; a second volute 702 and a second centrifugal fan 602 located inside the second volute 702; the air outlet of the first volute 701 is the first inner air outlet 1301, and the air outlet of the second volute 702 is the second inner air outlet 1302.

[0107] The installation of the first centrifugal fan 601 and the second centrifugal fan 602 can increase the indoor air volume.

[0108] The profiles of the first volute 701 and the second volute 702 are symmetrically arranged. The first centrifugal fan 601 and the second centrifugal fan 602 are driven by two motors or by one motor. When driven by two motors, the two motors rotate in opposite directions; when driven by one motor, the motor and one of the centrifugal fans are reversed via a gear. The opposite rotation of the two centrifugal fans helps to reduce the resistance of the gas flowing out of the volute.

[0109] Preferred, such as Figure 1 As shown, the air inlet of the first centrifugal fan 601 is located at the upper part of the vertical air conditioner indoor unit, and the air inlet of the second centrifugal fan 602 is located at the lower part of the vertical air conditioner indoor unit.

[0110] The first centrifugal fan 601 has a first guide member 801 at its upper part, and the air inlet of the first centrifugal fan 601 is connected to the first guide member 801; the second centrifugal fan 602 has a second guide member 802 at its lower part, and the air inlet of the second centrifugal fan 602 is connected to the second guide member 802. This design ensures that the two air inlets do not interfere with each other to a maximum extent, which is beneficial to increasing the air intake volume.

[0111] The indoor unit has two evaporators, which are located at the air inlets of the two centrifugal fans respectively.

[0112] The indoor unit is also equipped with two air inlet grilles, which are located upstream of the Li Enger evaporator, so that the air flows through the grilles first and then through the evaporator.

[0113] The first centrifugal fan 601 and the second centrifugal fan 602 are separated, so that the airflow between the first centrifugal fan 601 and the second centrifugal fan 602 does not interfere with each other, thereby improving the flow rate and velocity of the airflow.

[0114] This invention also proposes an air conditioner, including the aforementioned vertical air conditioner indoor unit. This air conditioner features low noise, multiple air delivery modes, and a better user experience.

The above description is only a preferred embodiment of the present invention.
