Technical Field

Detailed Implementation

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] The following is for reference. Figures 1-14 This invention describes an air conditioner 100 according to an embodiment of the present invention.

[0032] Reference Figures 1-4 According to an embodiment of the present invention, the air conditioner 100 includes an air conditioner body 10. The air conditioner body 10 extends horizontally in the length direction and vertically in the height direction. The air conditioner body 10 has an air duct 10a and an air outlet 10b. The air outlet 10b is located at the lower front part of the air conditioner body 10 and communicates with the air duct 10a. Cold air or hot air in the air duct 10a can flow out through the air outlet 10b to achieve a cooling or heating effect.

[0033] The air conditioner 100 also includes a first air guide assembly 20, which includes a first air guide plate 21 that is movable between a first position where the air outlet 10b is closed and a second position where the air outlet 10b is open.

[0034] Specifically, when the air conditioner 100 is turned off, the first air guide vane 21 can be moved to the first position of closing the air outlet 10b to reduce the probability of dust and other pollutants entering the air duct 10a from the air outlet 10b. When the air conditioner 100 is turned on, the first air guide vane 21 can be moved to the second position of opening the air outlet 10b, so that the airflow in the air duct 10a flows out of the air outlet 10b at a faster speed to achieve rapid cooling or heating.

[0035] Among them, reference Figure 3 and Figure 4 The air conditioner body 10 also includes a front panel 12, a baffle 13, and an air outlet grille 14. The baffle 13 extends from front to back, and the front end of the baffle 13 is connected to the lower end of the front panel 12. The air outlet grille 14 is located below the baffle 13 and between the front panel 12 and the air outlet 10b. The air outlet grille 14 helps to define the air outlet channel 15, which is connected to the air duct 10a. For example, the air outlet grille 14 can define the first air outlet channel 151.

[0036] Since the baffle 13 extends from front to back and its front end is connected to the lower end of the front panel 12, and the air outlet grille 14 is located below the baffle 13, the extension direction of the first air outlet channel 151 is also from front to back. When a part of the airflow in the air duct 10a flows through the first air outlet channel 151, it can flow along the extension direction of the baffle 13, thereby forming a sky curtain air outlet effect, which can bring a better user experience.

[0037] According to the embodiment of the present utility model, the air conditioner 100 provides an air outlet grille 14 below the baffle 13. The air outlet grille 14 can define a first air outlet channel 151 that communicates with the air duct 10a. This can add an additional air outlet area on the basis of the original air outlet 10b. Furthermore, since the air outlet grille 14 is located between the front panel 12 and the air outlet 10b, that is, the first air outlet channel 151 is located above the air duct 10a, the expansion angle of the air duct 10a can be increased, thereby achieving a larger range of air outlet.

[0038] Reference Figure 2 and Figure 4 In some embodiments, the air outlet grille 14 and the baffle 13 are integrally formed. This configuration can increase the connection reliability between the air outlet grille 14 and the baffle 13, thereby improving the durability of the air outlet grille 14. On the other hand, the integral forming process can realize the automated production of the air outlet grille 14 and the baffle 13, enabling the mass and rapid production of the air outlet grille 14 and the baffle 13, improving production efficiency and reducing production costs.

[0039] For example, the air vent grille 14 can also be used as a decorative element by hot stamping or changing different colors to enhance the aesthetics of the air conditioner 100.

[0040] Reference Figure 5 In some embodiments, the air outlet 10b is the first air outlet of the air conditioner 100, and the first air guide plate 21 has a plurality of first air dissipation holes 21a. The air outlet grille 14 is the second air outlet 10c of the air conditioner 100.

[0041] In a plane perpendicular to the length of the air conditioner body 10, the projected length of the first air guide plate 21 is L1, and the projected length of the second air outlet 10c is L2. The ratio of L1 to L2 is greater than or equal to 3. For example, the ratio of L1 to L2 can be 3, 3.5, 4, etc.

[0042] It should be noted that "the projection length L1 of the first air guide plate 21 in the plane" refers to the dimension of the projection of the first air guide plate 21 in the plane along its extension direction. Specifically, if the projection of the first air guide plate 21 in the plane is a straight line, then L1 is the distance between the two ends of the straight line; if the projection of the first air guide plate 21 in the plane is a curve, then L1 is the extension length of the curve; if the projection of the first air guide plate 21 in the plane is a combination of a straight line and a curve, then L1 is the sum of the distance between the two ends of the straight line and the extension length of the curve. "The projection length L2 of the second air outlet 10c in the plane" refers to the dimension of the projection of the second air outlet 10c in the plane along its extension direction.

[0043] Since the first air guide plate 21 is used to open and close the air outlet 10b, the projected length L1 of the first air guide plate 21 in the plane is positively correlated with the area of ​​the air outlet 10b, and the projected length of the second air outlet 10c in the plane is positively correlated with the area of ​​the second air outlet 10c.

[0044] Therefore, by limiting the ratio of L1 to L2 to be greater than or equal to 3, on the one hand, it can ensure the air volume of the air outlet 10b when the first air guide plate 21 is in the open air outlet 10b, so as to quickly adjust the indoor temperature. On the other hand, it can ensure the windless air outlet effect when the first air guide plate 21 is in the closed air outlet 10b and the air conditioner 100 is in the windless mode. It can also prevent users from observing a large opening, improve the aesthetics of the air conditioner 100, and bring a better visual experience to users.

[0045] Reference Figures 1-4 In some examples, the air outlet grille 14 includes a plurality of grille strips 141, which are spaced apart in the height direction of the air conditioning body 10. The grille strips 141 extend from back to front and in the length direction along the length direction of the air conditioning body 10. A first air outlet channel 151 is defined between two adjacent grille strips 141.

[0046] In the above technical solution, by setting the air outlet grille 14 to include multiple grille bars 141, the first air outlet channel 151 can be defined by each grille bar 141. The grille bars 141 extend from back to front, and the grille bars 141 can guide the airflow to gradually flow forward, thereby forming a canopy wind effect and improving the comfort of the airflow.

[0047] Furthermore, since the grille strips 141 extend from back to front, the first air outlet channel 151 defined between two adjacent grille strips 141 also extends from back to front. This adds a controllable air outlet area above the end of the air duct 10a, thereby increasing the width of the air outlet end of the air duct 10a. The air outlet 10b is located at the lower front part of the air conditioner body 10 and can outlet air diagonally downwards. Therefore, by combining the first air outlet channel 151 and the air outlet 10b, on the one hand, the air outlet angle can be increased in the height direction of the air conditioner 100 to achieve a wider air outlet range, and on the other hand, the width of the air duct 10a can be widened to enhance the size of the air outlet.

[0048] Reference Figure 3 and Figure 4 In some embodiments, the first air guide plate 21 has a plurality of first air diffusers 21a. The flow area of ​​the first air outlet channel 151 is larger than the flow area of ​​the first air diffusers 21a.

[0049] By setting the flow area of ​​the first air outlet channel 151 to be larger than the flow area of ​​the first air diffuser 21a, the flow resistance of the airflow can be reduced in the windless mode, allowing more airflow to flow out from the first air outlet channel 151, thereby ensuring the air volume of the air conditioner 100 in the windless mode.

[0050] Reference Figure 1 and Figure 2 In some examples, the first air outlet duct 151 is provided with a plurality of first partition ribs 1511, which are arranged at intervals along the length of the grille bar 141 to divide the first air outlet duct 151 into a plurality of first sub-ducts 151a.

[0051] Multiple first dividing ribs 1511 are arranged at intervals along the length of the grille bar 141. On the one hand, the first air outlet channel 151 can be divided into multiple first sub-channels 151a, thereby refining the airflow in the first air outlet channel 151 and dispersing the concentrated airflow into multiple small airflows, which enhances the air outlet effect in the windless mode. On the other hand, it can improve the structural strength of the air outlet grille 14, thereby improving the deformation resistance of the air outlet grille 14.

[0052] The flow area of ​​the first sub-channel 151a is larger than that of the first diffuser hole 21a. This arrangement increases the airflow rate of the first sub-channel 151a, thereby ensuring the airflow of the second outlet section 10c.

[0053] Reference Figure 2In some specific examples, the multiple first partition ribs 1511 in the first air outlet duct 151 are divided into two symmetrically arranged first partition rib groups 1511a, and the axis of symmetry is the center line of the air conditioner body 10 extending in the vertical direction. Any two first partition ribs 1511 in the two first partition rib groups 1511a extend at an angle away from each other in the length direction of the air conditioner body 10.

[0054] Specifically, the plurality of first partition bars 1511 are divided into a first partition bar group 1511a located on the left and a first partition bar group 1511a located on the right. The plurality of first partition bars 1511 in the first partition bar group 1511a located on the left gradually extend to the left, and the plurality of first partition bars 1511 in the first partition bar group 1511a located on the right gradually extend to the right.

[0055] In the above technical solution, by setting any two first partition ribs 1511 corresponding to the positions in the two first partition rib groups 1511a to extend obliquely away from each other in the length direction of the air conditioning body 10, the airflow can be dispersed out of the second air outlet 10c, thereby achieving a larger range of air outlet effect in the length direction of the air conditioning body 10.

[0056] Reference Figure 3 and Figure 4 , Figure 7 and Figure 8 In some specific examples, each grid strip 141 extends upwards gradually from back to front.

[0057] In the above technical solution, by setting each grille bar 141 to gradually extend upward from back to front, the first air outlet channel 151 that gradually extends upward from back to front can be defined by two adjacent grille bars 141. This can guide the airflow in the first air outlet channel 151, so that the airflow can gradually flow out upward, thereby forming the air outlet effect of the sky curtain wind, bringing a better user experience.

[0058] Reference Figure 8 In some specific examples, the dimension M of the grille strip 141 in the front-to-back direction is 10mm-40mm, for example, M can be 10mm, 12mm, 15mm, 30mm, 40mm, etc.

[0059] The “dimension of grille strip 141 in the front-to-back direction” here refers to the distance between the two ends of the projection of grille strip 141 on a plane perpendicular to the length direction of the air conditioner body 10.

[0060] If M is greater than 40mm, a longer portion of the grille bar 141 will be located within the air duct 10a, which will significantly obstruct the airflow from the air duct 10a to the air outlet 10b, thus affecting the airflow volume of the air outlet 10b. If M is less than 10mm, the grille bar 141 will have a smaller guiding effect on the airflow within the air duct 10a, meaning that less airflow will enter the first air outlet channel 151 through the guidance of the grille bar 141, resulting in a smaller airflow volume exiting the first air outlet channel 151.

[0061] Therefore, in the above technical solution, by setting the size of the grille bar 141 in the front-to-back direction to 10mm-40mm, on the one hand, the influence on the airflow to the air outlet 10b can be reduced, and on the other hand, a part of the airflow in the air duct 10a can be guided to the first air outlet channel 151 to ensure the air volume of the first air outlet channel 151.

[0062] Reference Figure 8 In some embodiments, the first air outlet duct 151 includes a first rear extension 1513 and a first front extension 1512. The first rear extension 1513 extends upward gradually from rear to front, and the first front extension 1512 extends upward gradually from rear to front. The rear end of the first front extension 1512 is connected to the front end of the first rear extension 1513.

[0063] In other words, both the first rear extension section 1513 and the first front extension section 1512 extend upwards gradually from back to front, thereby forming a first air outlet channel 151 that extends upwards gradually from back to front, so that the airflow in the first air outlet channel 151 can flow out upwards at an angle, forming the air outlet effect of the sky curtain wind.

[0064] In this design, the flow area of ​​the first rear extension section 1513 gradually decreases from rear to front, while the flow area of ​​the first front extension section 1512 gradually increases from rear to front. This configuration creates a Venturi effect, thereby increasing the airflow velocity within the first air outlet channel 151 and allowing the airflow exiting the first air outlet channel 151 to diffuse at a greater angle.

[0065] For example, the projection of the first rear extension 1513 onto a plane perpendicular to the length direction of the air conditioner body 10 is set at a1, where a1 < 30°. The projection of the first front extension 1512 onto a plane perpendicular to the length direction of the air conditioner body 10 is set at a2, where a2 < 30°.

[0066] If a1 is too large, it will cause vortices and reduce flow velocity stability; if a2 is too large, it may weaken the airflow separation effect, thus affecting the air outlet performance. In the above technical solution, by limiting a1 and a2 to meet the above range, vortices can be reduced, the airflow separation effect can be guaranteed, and thus the air outlet performance can be guaranteed.

[0067] Reference Figure 8 and Figure 9 In some specific embodiments, in the height direction of the air conditioner body 10, the rear end dimension b1 of the first rear extension 1513 is equal to the front end dimension b2 of the first front extension 1512. This setting ensures that the airflow flowing into the first air outlet duct 151 is consistent with the airflow flowing out of the first air outlet duct 151.

[0068] Reference Figure 8 and Figure 10 In some embodiments, the angle c1 between the extension direction of the first rear extension 1513 and the plane perpendicular to the height direction of the air conditioner body 10 is greater than the angle c2 between the extension direction of the first front extension 1512 and the plane perpendicular to the height direction of the air conditioner body 10.

[0069] Therefore, by setting c1 to be greater than c2, that is, by setting the flow area of ​​the first air outlet channel 151 to decrease first and then increase from back to front, the flow velocity of the airflow into the first air outlet channel 151 can be appropriately increased. When the airflow flows into the first front extension section 1512, the airflow velocity will gradually decrease again. This can increase the airflow in the first air outlet channel 151 without increasing the flow velocity of the airflow out of the first air outlet channel 151, so as to ensure the air outlet effect in the windless mode.

[0070] Reference Figure 8 In some examples, among the multiple grille bars 141, the bottommost grille bar 141 is the first grille bar 1411. In the front-back direction, the front end of the first grille bar 1411 does not extend beyond the front ends of the other grille bars 141. When the first air guide plate 21 is in the first position, the first air guide plate 21 covers the front end of the first grille bar 1411, and the first air guide plate 21 is flush with the front panel 12.

[0071] In the above technical solution, by setting the front end of the first grille strip 1411 to not exceed the front ends of the other grille strips 141 in the front-back direction, the first air guide plate 21 can be avoided. When the first air guide plate 21 closes the air outlet 10b, the first air guide plate 21 can cover the front end of the bottommost first grille strip 1411, thus preventing the first grille strip 1411 from colliding with the first air guide plate 21. By setting the first air guide plate 21 to be flush with the front panel 12 when the first air guide plate 21 is in the first position, the aesthetics of the air conditioner 100 can be increased, providing users with a good visual experience.

[0072] Reference Figure 9In some examples, among the multiple grille bars 141, the uppermost grille bar 141 is the second grille bar 1412, the baffle 13 and / or the front panel 12, and a second air outlet channel 152 communicating with the air duct 10a is defined between the second grille bar 1412.

[0073] With this configuration, the second air outlet channel 152 can be defined by the baffle 13 and / or the front panel 12 and the second grille strip 1412. This not only reduces the number of grille strips 141, but also shortens the distance between the first air guide plate 21 and the front panel 12, so that the appearance of the air conditioner 100 will not have a large opening, thus improving the aesthetics of the air conditioner 100.

[0074] In some specific examples, the baffle 13 gradually slopes downwards from front to back. This arrangement allows the baffle 13 to guide the airflow gradually upwards, thereby creating a canopy-like airflow effect. Especially when the air conditioner 100 is cooling, it can achieve the settling of the cold air from the canopy, preventing the cold air from blowing directly on the user and providing a better user experience.

[0075] In addition, since the front end of the baffle 13 is connected to the lower end of the front panel 12, when the air conditioner 100 is cooling, a portion of the cold air flowing out from the second air outlet 152 can be evenly applied to the front panel 12, making the overall temperature of the front panel 12 more uniform and preventing condensation from occurring on the front panel 12 due to uneven temperature.

[0076] Reference Figure 3 and Figure 4 In some embodiments, the first air guide plate 21 has a plurality of first air diffusers 21a. The flow area of ​​the second air outlet channel 152 is larger than the flow area of ​​the first air diffusers 21a.

[0077] By setting the flow area of ​​the second air outlet duct 152 to be larger than that of the first air diffuser 21a, the flow resistance of the airflow can be reduced in the windless mode, allowing more airflow to flow out from the second air outlet duct 152, thereby ensuring the air volume of the air conditioner 100 in the windless mode.

[0078] Reference Figure 1 and Figure 2 In some specific embodiments, the second air outlet channel 152 is provided with a plurality of second partition ribs 1521, which are arranged at intervals along the length of the air outlet grille 14 to divide the second air outlet channel 152 into a plurality of second sub-channels 152a.

[0079] Multiple second dividing ribs 1521 are arranged at intervals along the length of the air outlet grille 14. On the one hand, the second air outlet channel 152 can be divided into multiple second sub-channels 152a, which can play a certain role in dispersing the airflow and breaking down the concentrated airflow into multiple small airflows, thus enhancing the air outlet effect in the windless mode. On the other hand, it can improve the structural strength of the air outlet grille 14, thereby improving the deformation resistance of the air outlet grille 14 and the reliability of the connection between the air outlet grille 14 and the baffle 13.

[0080] The flow area of ​​the second sub-channel 152a is larger than that of the first diffuser hole 21a. This arrangement increases the airflow rate of the second sub-channel 152a, thereby ensuring the airflow of the second outlet section 10c.

[0081] Reference Figure 2 In some specific embodiments, the multiple second partition ribs 1521 in the second air outlet duct 152 are divided into two symmetrically arranged second partition rib groups 1521a, and the axis of symmetry is the center line of the air conditioner body 10 extending in the vertical direction. Any two second partition ribs 1521 in the two second partition rib groups 1521a that correspond to each other extend at an angle away from each other in the length direction of the air conditioner body 10.

[0082] Specifically, the plurality of second partition bars 1521 are divided into a second partition bar group 1521a located on the left and a second partition bar group 1521a located on the right. The plurality of second partition bars 1521 in the second partition bar group 1521a located on the left gradually extend to the left, and the plurality of second partition bars 1521 in the second partition bar group 1521a located on the right gradually extend to the right.

[0083] In the above technical solution, by setting any two second partition ribs 1521 corresponding to the positions in the two second partition rib groups 1521a to extend obliquely away from each other in the length direction of the air conditioning body 10, the airflow can be dispersed out of the second air outlet 10c, thereby achieving a larger range of air outlet effect in the length direction of the air conditioning body 10.

[0084] Reference Figure 8 and Figure 9 In some specific examples, in the height direction of the air conditioner body 10, the dimensions of the front end of the first air outlet duct 151, the dimensions of the rear end of the first air outlet duct 151, the dimensions of the front end of the second air outlet duct 152, and the dimensions of the rear end of the second air outlet duct 152 are equal.

[0085] It should be noted that "the dimensions of the front end of the first air outlet duct 151" refers to the front end dimensions of the first front extension section 1512, that is... Figure 9In the text b2, "the rear dimension of the first air outlet duct 151" refers to the rear dimension of the first rear extension section 1513, that is... Figure 9 In the text b1, "the dimension of the front end of the second air outlet duct 152" refers to the front end dimension of the second front extension section 1522, that is... Figure 9 In the text b4, "the rear end dimension of the second air outlet duct 152" refers to the rear end dimension of the second rear extension section 1523, that is... Figure 9 b3 in the middle.

[0086] This configuration ensures that the air intake and exhaust volume of the first air outlet channel 151 are consistent, and that the air intake and exhaust volume of the second air outlet channel 152 are consistent. It also helps to achieve uniform air output from the first air outlet channel 151 and the second air outlet channel 152.

[0087] Reference Figure 8 In some embodiments, the second air outlet duct 152 includes a second rear extension 1523 and a second front extension 1522. The second rear extension 1523 extends upward gradually from rear to front, and the second front extension 1522 extends upward gradually from rear to front. The rear end of the second front extension 1522 is connected to the front end of the second rear extension 1523.

[0088] In other words, both the second rear extension section 1523 and the second front extension section 1522 extend upwards gradually from back to front, thereby forming a second air outlet channel 152 that extends upwards gradually from back to front. This allows the airflow in the second air outlet channel 152 to flow out upwards at an angle, creating a canopy-like air outlet effect.

[0089] In this design, the flow area of ​​the second rear extension section 1523 gradually decreases from rear to front, while the flow area of ​​the second front extension section 1522 gradually increases from rear to front. This configuration creates a Venturi effect, thereby increasing the airflow velocity within the second air outlet duct 152 and allowing the airflow exiting the second air outlet duct 152 to diffuse at a greater angle.

[0090] For example, the projection of the second rear extension 1523 onto a plane perpendicular to the length direction of the air conditioner body 10 is set at a3, where a3 < 30°. The projection of the second front extension 1522 onto a plane perpendicular to the length direction of the air conditioner body 10 is set at a4, where a4 < 30°.

[0091] If a3 is too large, it will cause vortices and reduce flow velocity stability; if a4 is too large, it may weaken the airflow separation effect, thus affecting the air outlet performance. In the above technical solution, by limiting a3 and a4 to meet the above range, vortices can be reduced, the airflow separation effect can be guaranteed, and thus the air outlet performance can be guaranteed.

[0092] Reference Figure 8 and Figure 9 In some specific embodiments, in the height direction of the air conditioner body 10, the rear end dimension b3 of the second rear extension 1523 is equal to the front end dimension b4 of the second front extension 1522. This arrangement ensures that the airflow flowing into the second air outlet duct 152 is consistent with the airflow flowing out of the second air outlet duct 152.

[0093] Reference Figure 8 and Figure 10 In some embodiments, the angle c3 between the extension direction of the second rear extension 1523 and the plane perpendicular to the height direction of the air conditioner body 10 is greater than the angle c4 between the extension direction of the second front extension 1522 and the plane perpendicular to the height direction of the air conditioner body 10.

[0094] Therefore, by setting c3 to be greater than c4, that is, by setting the flow area of ​​the second air outlet channel 152 to decrease first and then increase from back to front, the flow velocity of the airflow into the second air outlet channel 152 can be appropriately increased. When the airflow flows into the second front extension section 1522, the airflow velocity will gradually decrease again. This can increase the airflow in the second air outlet channel 152, but will not increase the flow velocity of the airflow out of the second air outlet channel 152, so as to ensure the air outlet effect in the windless mode.

[0095] Reference 8- Figure 10 In some examples, when the first air guide plate 21 is in the first position, the front end of the second grille strip 1412 is located between the top of the first air guide plate 21 and the bottom of the front panel 12. This makes the appearance of the air conditioner 100 relatively flat when the first air guide plate 21 is in the first position, which helps to improve the aesthetics of the air conditioner 100.

[0096] Reference Figure 11 and Figure 12 In some examples, the air duct 10a has a first air duct wall 101 and a second air duct wall 102 disposed opposite to each other, the first air duct wall 101 being located above the second air duct wall 102, and the first air duct wall 101 being provided with a volute tongue 11.

[0097] The second grille bar 1412 extends upwards gradually from back to front, with its rear end lower than the lowest point of the first air duct wall 101. This guides the airflow within the air duct 10a, allowing a portion of the airflow to flow into the second air outlet channel 152 and then flow upwards along the extension direction of the second air outlet channel 152.

[0098] In the above technical solution, by setting the rear end of the second grille bar 1412 to be lower than the lowest point of the first air duct wall 101, part of the airflow in the air duct 10a can be guided into the second air outlet channel 152. Since the second grille bar 1412 gradually extends upward from back to front, the airflow can act on the front panel 12 after flowing out from the second air outlet channel 152, so that the overall temperature of the front panel 12 is more uniform, which can avoid the problem of condensation on the front panel 12 due to its own temperature difference.

[0099] Continue to refer to Figure 11 and Figure 12 In some specific examples, the distance H between the rear end of the second grille bar 1412 and the lowest point of the first air duct wall 101 in the height direction of the air conditioning body 10 is less than 10mm. For example, H can be 1mm, 2mm, 3mm, 7mm, 9mm, etc.

[0100] If H is greater than or equal to 10mm, that is, the distance between the rear end of the second grille bar 1412 and the lowest point of the first air duct wall 101 in the height direction of the air conditioner body 10 is too large, then too much of the second grille bar 1412 extends into the air duct 10a. Although it can guide some of the airflow in the air duct 10a to the second air outlet 152, it will greatly obstruct the airflow to the first air outlet 151, and may even cause insufficient airflow at the air outlet 10b.

[0101] Therefore, in the above technical solution, by setting the distance between the rear end of the second grille strip 1412 and the lowest point of the first air duct wall 101 in the height direction of the air conditioning body 10 to less than 10mm, on the one hand, a portion of the airflow in the air duct 10a can be guided to flow to the second air outlet duct 152, thereby solving the condensation problem of the front panel 12, and on the other hand, the impact on the airflow to the air outlet 10b can be reduced, so that there is sufficient airflow at the air outlet 10b.

[0102] Reference Figure 12 In some embodiments, the baffle 13 extends upward gradually from back to front, and the baffle 13 constitutes at least a part of the first air duct wall 101, the lowest point of the first air duct wall 101 being located between the baffle 13 and the volute tongue 11.

[0103] With this configuration, the first air duct wall 101 can be extended by using the baffle 13, thereby extending the length of the air duct 10a, and can guide the airflow in part of the air duct 10a, so that the airflow can flow into the second air outlet duct 152 along the extension direction of the baffle 13.

[0104] Reference Figure 12In some embodiments, the air duct 10a has a first air duct wall 101 and a second air duct wall 102 disposed opposite to each other, the first air duct wall 101 being located above the second air duct wall 102 and having a volute tongue 11 thereon.

[0105] The first air duct wall 101 includes a first wall body 1011 and a baffle 13. The first wall body 1011 extends downwards gradually from back to front, and the baffle 13 extends upwards gradually from back to front. The rear end of the baffle 13 is connected to the first wall body 1011. In a plane perpendicular to the length direction of the air conditioning body 10, the angle between the projection of the baffle 13 and the extended projection line of the first wall body 1011 is greater than or equal to 10°. For example, the angle between the projection of the baffle 13 and the extended projection line of the first wall body 1011 can be 10°, 11°, 13°, 19°, etc.

[0106] If the angle between the projection of the baffle 13 and the extended projection line of the first wall body 1011 is less than 10°, that is, the transition between the first wall body 1011 and the baffle 13 is relatively smooth, when the airflow in the air duct 10a flows near the first wall body 1011, this will result in only a small amount of airflow flowing to the second air outlet duct 152, thereby affecting the amount of airflow flowing out from the second air outlet duct 152.

[0107] Therefore, by limiting the plane to the length direction of the air conditioner body 10, the angle between the projection of the baffle 13 and the extension line of the projection of the first wall body 1011 needs to be set to be greater than or equal to 10°. This allows the first wall body 1011 to guide part of the airflow in the air duct 10a to the baffle 13, and ensures that part of the airflow can flow into the second air outlet duct 152 along the extension direction of the baffle 13.

[0108] Reference Figure 12 and Figure 13 In some specific embodiments, the baffle 13 includes a first plate portion 131, a second plate portion 132 and a third plate portion 133 arranged from back to front, and the first plate portion 131, the second plate portion 132 and the third plate portion 133 all extend upward gradually from back to front.

[0109] In the plane perpendicular to the length direction of the air conditioner body 10, the angle k1 between the projection of the first plate portion 131 and the extended projection line of the first wall body 1011 is 10°-30°, the angle k2 between the projection of the second plate portion 132 and the extended projection line of the first wall body 1011 is 40°-60°, and the angle k3 between the projection of the third plate portion 133 and the extended projection line of the first wall body 1011 is 30°-50°.

[0110] For example, in a plane perpendicular to the length direction of the air conditioner body 10, the angle k1 between the projection of the first plate portion 131 and the extended projection line of the first wall body 1011 is 10°, 15°, 19°, 25°, 30°, etc.; the angle k2 between the projection of the second plate portion 132 and the extended projection line of the first wall body 1011 is 40°, 45°, 50°, 55°, 60°, etc.; and the angle k3 between the projection of the third plate portion 133 and the extended projection line of the first wall body 1011 is 30°, 35°, 40°, 45°, 50°, etc.

[0111] With this configuration, on the one hand, the first wall body 1011 can guide part of the airflow inside the air duct 10a to the baffle 13, and flow into the second air outlet channel 152 along the extension direction of the baffle 13, ensuring that there is enough airflow from the air duct 10a into the second air outlet channel 152. On the other hand, the first plate portion 131, the second plate portion 132 and the third plate portion 133 can be used to make the airflow inside the second air outlet channel 152 flow upward at an angle, thereby increasing the air outlet angle of the air conditioner 100 in the height direction.

[0112] Continue to refer to Figure 12 and Figure 13 In some embodiments, the lower end of the front panel 12 has a flange 121, which extends downwards gradually from front to back and is connected to the baffle 13. In a plane perpendicular to the length direction of the air conditioner body 10, the angle k4 between the projection of the flange 121 and the extended projection line of the first wall body 1011 is 20°-40°. For example, k4 can be 20°, 21°, 25°, 35°, 40°, etc.

[0113] In the above technical solution, by setting the flange 121 of the front panel 12 to gradually slope downward from front to back and connecting the flange 121 to the baffle 13, the flange 121 can be inserted into the second air outlet duct 152, making the front panel 12 of the air conditioner 100 look more beautiful and providing users with a good visual experience; by setting the angle between the projection of the flange 121 and the projection extension line of the first wall body 1011 to 20°-40°, the airflow in the second air outlet duct 152 can be guided to flow upward at an angle, thereby improving the comfort of the airflow.

[0114] Reference Figures 11-14 In a further embodiment, the air conditioner 100 also includes a second air guide assembly 30, which includes a second air guide plate 31, which is movably disposed within the air duct 10a.

[0115] By driving the second air guide plate 31 to move, the extension direction of the second air guide plate 31 can be changed, thereby adjusting the air outlet direction and the airflow ratio to the air outlet 10b, the first air outlet channel 151 and the second air outlet channel 152, so as to achieve multi-level air outlet to meet different usage needs.

[0116] Reference Figure 7 In some examples, the second air guide plate 31 has a non-perforated structure. When the air conditioner 100 is working, the second air guide plate 31 can be controlled to move within the air duct 10a, thereby adjusting the ratio of airflow in the air duct 10a to the air outlet 10b, the first air outlet channel 151, and the second air outlet channel 152.

[0117] For example, when the second air guide plate 31 is moved to the point where its extension direction is consistent with the airflow direction in the air duct 10a, or when its extension direction forms a small angle with the airflow direction in the air duct 10a, the airflow in the air duct 10a experiences less resistance from the second air guide plate 31 and can flow directly to the air outlet 10b, and partly to the first air outlet channel 151 and the second air outlet channel 152.

[0118] For example, when the second air guide plate 31 moves to the point where the extension direction of the second air guide plate 31 forms a large angle with the airflow direction in the air duct 10a, the second air guide plate 31 will obstruct the airflow in the air duct 10a, thereby causing a small portion of the airflow to flow to the air outlet 10b, and most of the airflow to flow to the first air outlet channel 151 and the second air outlet channel 152.

[0119] Reference Figure 5 and Figure 6 , Figure 11 and Figure 14 In other examples, the first air guide plate 21 has a plurality of first air diffusers 21a. The second air guide plate 31 has a plurality of second air diffusers 31a.

[0120] When the air conditioner 100 is working, the second air guide plate 31 can be controlled to move within the air duct 10a, thereby adjusting the ratio of airflow in the air duct 10a to the air outlet 10b, the first air outlet channel 151, and the second air outlet channel 152. However, during the process of adjusting the airflow, since the second air guide plate 31 has multiple second air diffusers 31a, in the embodiment where the first air guide plate 21 has multiple first air diffusers 21a, in the windless mode, the second air guide plate 31 can also cooperate with the first air guide plate 21 to achieve windless airflow.

[0121] For example, in the windless mode, when the air conditioner 100 is cooling, the second air guide plate 31 moves to a position where the extension direction of the second air guide plate 31 forms a large angle with the airflow direction in the air duct 10a. When the airflow passes through the second air guide plate 31, the multiple second air diffusers 31a initially disperse the airflow, that is, initially reduce the airflow velocity. When the airflow passes through the first air guide plate 21, the multiple first air diffusers 21a further disperse the airflow and reduce the airflow velocity again, thereby achieving a windless airflow effect at the air outlet 10b.

[0122] In the above technical solution, by setting the second air guide plate 31 to a non-perforated structure, the ratio of airflow to the air outlet 10b, the first air outlet channel 151 and the second air outlet channel 152 can be adjusted; by setting the second air guide plate 31 to have multiple second air diffusers 31a, on the one hand, the ratio of airflow to the air outlet 10b and the second air outlet can be adjusted, and on the other hand, the airflow to the air outlet 10b can be initially dispersed to reduce the flow rate, thereby assisting the first air guide plate 21 in achieving a windless air outlet effect at the air outlet 10b.

[0123] In some optional embodiments, the first air guide plate 21 is provided with a plurality of first air dissipation holes 21a. The windless mode has a first stage and a second stage. In the first stage, the second air guide plate 31 gradually extends forward from top to bottom so that the second air guide plate 31 is close to the first air guide plate 21. In the second stage, the second air guide plate 31 gradually extends forward from bottom to top so that the second air guide plate 31 is close to the second air outlet 10c.

[0124] Specifically, when the air conditioner 100 is cooling, the user can control the air conditioner 100 to enter the windless mode according to the user's needs. In the first stage of the windless mode, since the indoor temperature is high, the second air guide plate 31 can be moved to the point where the extension direction of the second air guide plate 31 is consistent with the airflow direction in the air duct 10a, or moved to the point where the extension direction of the second air guide plate 31 forms a small angle with the airflow direction in the air duct 10a. At this time, the airflow in the air duct 10a is subject to less resistance from the second air guide plate 31.

[0125] At this stage, the first air guide plate 21 is in the closed air outlet 10b state. The first air guide plate 21 has a large resistance to airflow, and less airflow passes through per unit time. On the other hand, the air outlet grille 14 has a small resistance to airflow, so more airflow passes through per unit time. It blows out obliquely upward along the extension direction of the air outlet channel 15, which can achieve rapid cooling of the room. While ensuring a large air volume and sufficient cooling capacity, it can also meet the comfort requirements of a windless feeling.

[0126] In the second stage of the windless mode, since the indoor temperature has already dropped to a certain range, too much airflow would make the user too cold. Therefore, the second air guide plate 31 can be controlled to extend at a large angle to the airflow direction within the duct 10a. For example, the extension direction of the second air guide plate 31 can be made almost perpendicular to the airflow direction within the duct 10a. At this time, the resistance of the second air guide plate 31 to the airflow within the duct 10a increases rapidly, and less airflow passes through the second diffuser hole 31a. As a result, very little airflow passes through the multiple first diffuser holes 21a on the first air guide plate 21 and the second air outlet 10c. That is, under the condition of outputting a certain amount of cooling to maintain the indoor temperature, the comfort of the windless mode can be increased, bringing a good user experience.

[0127] When the air conditioner is heating at 100 degrees Celsius, the control mechanism of the windless mode is similar, so it will not be described in detail here.

[0128] By setting the windless mode to have a first stage and a second stage, the air conditioner 100 can quickly adjust the indoor temperature in the first stage of the windless mode. After the indoor temperature is within a suitable range, the air conditioner 100 can switch to the second stage of the windless mode, which can reduce the air volume of the air conditioner 100. This ensures the user's experience while maintaining cooling or heating.

[0129] For example, the windless mode can also be divided into more stages, controlling the state of the second air guide plate 31 according to different stages, thereby achieving multi-dimensional control. For instance, the second air guide plate 31 can be controlled to move continuously or intermittently to adjust the air outlet 10b and the air outlet section 10c's airflow direction and volume.

[0130] Reference Figure 5 and Figure 6 In some embodiments, the air conditioner 100 also includes a temperature detection element (not shown in the figure), which is used to detect the ambient temperature of the air conditioner 100. When the temperature detection element detects that the ambient temperature of the air conditioner 100 is within a preset temperature range, the air conditioner 100 controls the second air guide plate 31 to move to a state that gradually extends forward from bottom to top.

[0131] Specifically, when the air conditioner 100 is cooling, in the first stage of the windless mode, if the temperature sensor detects that the ambient temperature of the air conditioner 100 is higher than the maximum value of the preset temperature range, the second air guide plate 31 is controlled to maintain a state of gradually extending forward from top to bottom, so that the second air guide plate 31 is close to the first air guide plate 21 to achieve rapid cooling; if the temperature sensor detects that the ambient temperature of the air conditioner 100 is within the preset temperature range, the second air guide plate 31 is controlled to move to a state of gradually extending forward from bottom to top, that is, the air conditioner 100 enters the second stage of the windless mode, so that the ambient temperature of the air conditioner 100 is maintained within a certain temperature range.

[0132] In the above technical solution, by setting the air conditioner 100 to include a temperature detection element, the ambient temperature of the air conditioner 100 can be detected by the temperature detection element, and the detected temperature can be compared with a preset temperature range, thereby controlling the air conditioner 100 to be in the first or second stage of the windless mode, so that the ambient temperature is within a suitable temperature range, bringing a good user experience.

[0133] Reference Figure 7 and Figure 10 In a further embodiment, the air conditioner 100 also includes a sway assembly 40, which includes a plurality of sway blades 41 that are swayably disposed within the air duct 10a and are located upstream of the second air guide plate 31 in the airflow direction.

[0134] In the above technical solution, by oscillatingly arranging multiple oscillating blades 41 within the air duct 10a, the airflow distribution within the air duct 10a can be changed. For example, the airflow within the air duct 10a can be made to flow evenly, thereby allowing the airflow to flow out evenly from the air outlet 10b, the first air outlet channel 151, or the second air outlet channel 152. On the other hand, the air outlet direction can be adjusted, thereby achieving directional or non-directional air delivery.

[0135] For example, when the air conditioner 100 is in a windless mode, the first air guide plate 21 closes the air outlet 10b, and multiple sway blades 41 swing within the air duct 10a, so that the airflow from the air duct 10a can spread to the air outlet 10b, the first air outlet channel 151, or the second air outlet channel 152 in a wider range in the left and right directions.

[0136] Reference Figure 7 and Figure 10 In some specific embodiments, the air duct 10a has a first air duct wall 101 and a second air duct wall 102 disposed opposite to each other, and a volute tongue 11 is provided on the first air duct wall 101. The louver assembly 40 is disposed on the first air duct wall 101 or the second air duct wall 102, and the second air guide assembly 30 is disposed on the first air duct wall 101 or the second air duct wall 102.

[0137] For example, the sway blade assembly 40 and the second air guide assembly 30 are both disposed on the first air duct wall 101, and the sway blade assembly 40 is located upstream of the second air guide assembly 30 in the airflow direction.

[0138] For example, both the sway vane assembly 40 and the second air guide assembly 30 are disposed on the second air duct wall 102, and the sway vane assembly 40 is located upstream of the second air guide assembly 30 in the airflow direction.
