[0031] The air conditioner 100 of this utility model is described below with reference to the accompanying drawings.

[0032] According to the embodiment of the present utility model, the air conditioner 100, such as Figure 1 and Figure 2 As shown, the air conditioner 100 includes: a housing 1, an indoor heat exchanger 2, and an air duct assembly 3. The housing 1 includes a front grille 11, which includes an air inlet grille 111 and an air outlet grille 112. The indoor heat exchanger 2 is located inside the housing 1. The air inlet grille 111 is located on the air inlet side of the indoor heat exchanger 2. The air duct assembly 3 is located inside the housing 1. The air outlet grille 112 is located on the front side of the air duct assembly 3, and the air duct assembly 3 guides air towards the air outlet grille 112.

[0033] The housing 1 is the outer contour part of the air conditioner 100. The housing 1 includes a front grille 11, which is located on the front side of the housing 1. The front grille 11 includes an air inlet grille 111 and an air outlet grille 112. The air conditioner 100 can take in air through the air inlet grille 111 and can take out air through the air outlet grille 112.

[0034] The air conditioner 100 also includes an indoor heat exchanger 2 and an air duct assembly 3 disposed within the casing 1. An air inlet grille 111 is located on the air inlet side of the indoor heat exchanger 2. The airflow entering through the air inlet grille 111 exchanges heat with the indoor heat exchanger 2 to regulate the indoor temperature. The air duct assembly 3 directs airflow towards the front air outlet grille 112. The heat-exchanged airflow is guided by the air duct assembly 3 to the air outlet grille 112, thereby regulating the indoor temperature.

[0035] By providing an air intake grille 111 on the front side of the casing 1, compared to a solid front panel design, this invention adds a ventilation path at the front of the casing, utilizing the front panel of the air conditioner 100 for air intake, thereby improving the functionality of the front panel of the air conditioner 100. When air intake is provided using the air intake grille 111, and an air inlet is also provided on the top wall of the air conditioner 100, the air intake volume of the air conditioner 100 can be increased, which is beneficial to improving the heat exchange efficiency of the air conditioner 100.

[0036] Furthermore, by setting the air inlet grille 111, users can be prevented from putting their hands into the housing 1 through the air inlet grille 111, so as to facilitate the installation and subsequent maintenance of the air conditioner 100 and other operations that require contact with the air conditioner 100, which helps to reduce the impact on the internal structure of the housing 1 during operation.

[0037] By providing an air outlet grille 112 on the front side of the casing 1, the airflow is guided by the grille 112 before exiting, reducing turbulence and improving airflow stability. Furthermore, compared to an air outlet located below a solid front panel, the air outlet grille 112 provides better airflow guidance, thus improving the airflow performance of the air conditioner 100. For example, the air outlet grille 112 can guide the airflow upwards, increasing the forward airflow distance and expanding the airflow coverage, thereby improving the heat exchange efficiency of the air conditioner 100. Also for example, the air outlet grille 112 can guide the airflow downwards, pressing it down to avoid direct airflow onto the body, reducing discomfort from direct airflow. And also for example, the air outlet grille 112 can guide the airflow left and right, thereby increasing the left-right airflow coverage of the air conditioner 100.

[0038] Similarly, by setting the air outlet grille 112, users can be prevented from putting their hands into the housing 1 through the air outlet grille 112, so as to facilitate the installation and subsequent maintenance of the air conditioner 100 and other operations that require contact with the air conditioner 100, which helps to reduce the impact on the internal structure of the housing 1 during operation.

[0039] In addition, the air inlet and outlet of the front of the housing 1 are equipped with grille structures, which can improve the overall appearance of the air conditioner 100 and reduce the abruptness of setting up the air outlet grille 112 or the air inlet grille 111 separately.

[0040] According to the embodiment of the present utility model, by providing an air inlet grille 111 and an air outlet grille 112 on the front side of the housing 1, the functionality of the front panel structure of the air conditioner 100 can be improved, the air intake volume of the air conditioner 100 can be increased, and the air outlet effect of the air conditioner 100 can be improved, which is conducive to improving the ventilation and heat exchange efficiency of the air conditioner 100.

[0041] In some embodiments of this utility model, such as Figure 3 As shown, the air intake grille 111 includes a plurality of first grille bars 1111 arranged in the vertical direction, and an air intake channel 1112 is defined between adjacent first grille bars 1111. The air outlet end 1111b of the first grille bar 1111 is lower than the air inlet end 1111a of the first grille bar 1111.

[0042] The air intake grille 111 includes first grille bars 1111 spaced apart in the vertical direction. An air intake channel 1112 is defined between two adjacent first grille bars 1111, and airflow flows into the housing 1 along the air intake channel 1112. The air intake grille 111 is located on the front side of the housing 1, and airflow flows into the housing 1 from front to back through the air intake grille 1111. Therefore, the air intake end 1111a of the first grille bar 1111 is located in front of the air outlet end 1111b of the first grille bar 1111.

[0043] The air outlet end 1111b of the first grille 1111 is lower than the air inlet end 1111a of the first grille 1111. The air outlet end 1111b of the first grille 1111, located at the rear, extends downwards. From a front-to-back visual perspective, the air outlet end 1111b of the first grille 1111 blocks the rear end of the air inlet channel 1112. The air outlet end 1111b of the first grille 1111 can cover the rear structure of the first grille 1111, improving the appearance of the internal structure and enhancing the visual effect. At the same time, since the air outlet end 1111b of the first grille 1111 is lower than the air inlet end, the airflow can flow into the casing 1 more quickly after passing through the air inlet channel 1112, resulting in higher air intake efficiency and increasing the air intake volume of the air conditioner 100.

[0044] In some embodiments of this utility model, such as Figure 3 As shown, a portion of the first grille 1111 bends and extends downward and backward so that the air outlet end 1111b of the first grille 1111 is lower than the air inlet end 1111a of the first grille 1111.

[0045] The air outlet 1111b of the first grid bar 1111 is located behind the air inlet 1111a of the first grid bar 1111. A portion of the first grid bar 1111 bends and extends downward and backward, so that the air outlet 1111b of the first grid bar 1111 is lower than the air inlet 1111a of the first grid bar 1111. The downward and backward bending of a portion of the first grid bar 1111 can smoothly guide the airflow to the air outlet, which is beneficial to increasing the air intake volume.

[0046] In some embodiments of this utility model, such as Figure 3 As shown, the portion of the first grille 1111 near the air inlet end 1111a extends horizontally, while the portion of the first grille 1111 near the air outlet end 1111b bends downwards and backwards. This facilitates the rapid flow of air into the air inlet channel 1112 and allows the airflow to be quickly guided into the housing 1, thereby improving air intake efficiency.

[0047] In some embodiments of this utility model, such as Figure 3As shown, the air intake grille 111 includes a plurality of first grille bars 1111 arranged in the vertical direction. An air intake channel 1112 is defined between adjacent first grille bars 1111. The distance between the air outlet ends of the air intake channel 1112 in the vertical direction is H1, and the distance between the air inlet ends of the air intake channel 1112 in the vertical direction is H2, where H2 < H1.

[0048] The air intake grille 111 includes first grille bars 1111 spaced apart in the vertical direction. An air intake channel 1112 is defined between two adjacent first grille bars 1111. Airflow flows into the housing 1 along the air intake channel 1112. The airflow flows from the air intake end of the air intake channel 1112 to the air outlet end of the air intake channel 1112.

[0049] The vertical spacing H1 of the air outlet end of the air inlet channel 1112 is greater than the vertical spacing H2 of the air inlet end of the air inlet channel 1112. The air inlet channel 1112 has a widening shape from the air inlet end to the air outlet end, which is conducive to airflow and can improve the air intake efficiency of the air conditioner 100.

[0050] In some embodiments of this utility model, such as Figure 3 As shown, the spacing H1 between the air outlet end of the air inlet channel 1112 in the height direction and the spacing H2 between the air inlet end of the air inlet channel 1112 in the height direction satisfy: H1 > H2 > 2mm.

[0051] The air inlet channel 1112 has a height dimension greater than 2mm, which facilitates airflow into the housing 1 through the air inlet channel 1112 and can improve air intake efficiency.

[0052] In some embodiments of this utility model, such as Figure 3 As shown, the air outlet grille 112 includes a plurality of second grilles 1121 spaced apart in the vertical direction, and at least a portion of the upper surface and / or lower surface of the second grilles 1121 are formed as a first air guide surface 1121a extending obliquely forward and upward.

[0053] Airflow exits through the air outlet grille 112, which includes multiple second grilles 1121 spaced apart vertically. These second grilles guide the airflow. A first air guide surface 1121a extends forward and upward at an angle, guiding the airflow in this direction. This increases the forward air delivery distance, expands the airflow coverage, and improves the heat exchange efficiency of the air conditioner 100. Furthermore, when the air conditioner 100 is cooling, by guiding the airflow forward and upward, cold air can be transported over long distances, allowing the cold air to naturally sink from top to bottom, reducing the discomfort caused by direct cold air blowing on the body and improving the heat exchange effect.

[0054] Optionally, at least a portion of the upper surface of the second grid bar 1121 is formed as a first air guiding surface 1121a, or at least a portion of the lower surface of the second grid bar 1121 is formed as a first air guiding surface 1121a, or at least a portion of the upper surface of the second grid bar 1121 is formed as a first air guiding surface 1121a, and at least a portion of the lower surface of the second grid bar 1121 is formed as a first air guiding surface 1121a.

[0055] In some embodiments of this utility model, such as Figure 3 As shown, the entire upper surface of the second grid bar 1121 is formed as a first air guiding surface 1121a, and the portion of the lower surface of the second grid bar 1121 near the air outlet end 1121c is also formed as a first air guiding surface 1121a, while the portion of the lower surface of the second grid bar 1121 near the air inlet end 1121b extends horizontally. Both the upper and lower surfaces of the second grid bar 1121 have first air guiding surfaces 1121a, resulting in better airflow guidance.

[0056] In some embodiments of this utility model, such as Figure 3 As shown, the angle between the first air guiding surface 1121a and the horizontal plane S is a2, where 0°<a2≤30°.

[0057] When the angle between the first air guide surface 1121a and the horizontal plane S is too large, it will increase the wind resistance of the air outlet grille 112, which is not conducive to airflow. Therefore, it is optimal to design the angle a2 between the first air guide surface 1121a and the horizontal plane S to be 0°<a2≤30°, which can improve the guiding effect of airflow and help reduce the wind resistance of the air outlet grille 112.

[0058] Optionally, the angle α2 between the first air guiding surface 1121a and the horizontal plane S can be 5°, 10°, 20°, 25°, 30°, etc.

[0059] In some embodiments of this utility model, such as Figure 3 As shown, the thickness of the air inlet end 1121b of the second grille 1121 is less than the thickness of the air outlet end 1121c of the second grille 1121.

[0060] Airflow flows between two adjacent second grilles 1121. The air inlet end 1121b of the second grille 1121 is thin and the air outlet end 1121c of the second grille 1121 is thick, which is conducive to the airflow flowing into the air passage 1122 between the second grilles 1121 and helps to improve the air outlet efficiency of the air conditioner 100.

[0061] In some embodiments of this utility model, such as Figure 3As shown, an air passage 1122 is defined between two adjacent second grid bars 1121. The distance between the air inlet end of the air passage 1122 in the height direction is H3, and the distance between the air outlet end of the air passage 1122 in the height direction is H4, satisfying: H3 > H4.

[0062] The spacing H3 of the air inlet end of the air passage 1122 in the vertical direction is greater than the spacing H4 of the outlet end of the air passage 1122 in the vertical direction. The air passage 1122 has a narrowing shape from the inlet end to the outlet end. On the one hand, this can accelerate the flow of air from the air duct assembly 3 into the air passage 1122, thereby improving the air outlet efficiency. On the other hand, it can increase the air velocity flowing out of the outlet grille 112, thereby increasing the forward air delivery distance and improving the airflow coverage. In some embodiments of this utility model, the spacing H3 between the air inlet end of the air passage 1122 in the height direction and the spacing H4 between the air outlet end of the air passage 1122 in the height direction satisfy: H3 > H4 > 1.5 mm. The dimension of the air passage 1122 in the height direction is greater than 1.5 mm, which facilitates the airflow to flow out through the air outlet grille 112.

[0063] In some embodiments of this utility model, such as Figure 3 As shown, the entire upper surface of the second grid bar 1121 is formed as the first air guide surface 1121a, and the portion of the lower surface of the second grid bar 1121 near the air outlet end 1121c of the second grid bar 1121 is formed as the first air guide surface 1121a, while the portion of the lower surface of the second grid bar 1121 near the air inlet end 1121b of the second grid bar 1121 extends in the horizontal direction.

[0064] Therefore, the distance between the lower and upper surfaces of the second grid strip 1121 is smaller near the air inlet end 1121b and gradually increases towards the air outlet end 1121c. The distance between the lower and upper surfaces of the second grid strip 1121 is larger near the air outlet end 1121c and remains unchanged towards the air outlet end 1121c. An air passage 1122 is defined between two adjacent second grid strips 1121. The spacing between the air inlets of the air passage 1122 in the height direction is H3, and the spacing between the air outlets of the air passage 1122 in the height direction is H4, which satisfies the condition: H3 > H4.

[0065] The air passage 1122 narrows from the air inlet to the air outlet, then extends forward and upward at an angle, while the spacing of the air passage 1122 in the vertical direction remains unchanged. This accelerates the flow of air from the duct assembly 3 into the air passage 1122 and directs the airflow forward and upward, thereby improving the air outlet effect of the air conditioner 100.

[0066] In some embodiments of this utility model, such as Figure 3As shown, the rear end of the air intake grille 111 protrudes beyond the rear end of the air outlet grille 112.

[0067] The rear end of the air intake grille 111 is the air outlet, and the rear end of the air outlet grille 112 is the air intake. By designing the rear end of the air intake grille 111 to protrude from the rear end of the air outlet grille 112, the airflow guidance effect can be improved, making it easier for airflow to flow in from the air intake grille 111 and improving air intake efficiency.

[0068] Furthermore, the rear end of the air intake grille 111 protrudes beyond the rear end of the air outlet grille 112, which enhances the guiding effect on airflow without affecting the front appearance of the front grille 11.

[0069] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the front grille 11 also includes a transition grille 113 located between the air intake grille 111 and the air outlet grille 112, and the transition grille 113 is provided with a plurality of blind holes 1133.

[0070] A transition grille 113 is provided between the air inlet grille 111 and the air outlet grille 112, which increases the distance between the air inlet grille 111 and the air outlet grille 112. This improves the situation where the airflow flows directly back to the air inlet grille 111 after exiting the air outlet grille 112, thereby improving the heat exchange efficiency of the air conditioner 100.

[0071] Furthermore, by providing a transition grille 113 between the air intake grille 111 and the air outlet grille 112, the front grille 11 consists of the air intake grille 111, the transition grille 113, and the air outlet grille 112 from top to bottom. This allows the air intake grille 111 and the air outlet grille 112 to be connected as a whole, which can improve the overall integrity of the front grille 11 and reduce the abrupt appearance of setting the air outlet grille 112 and the air intake grille 111 separately.

[0072] The transition grille 113 is only used to increase the distance between the air intake grille 111 and the air outlet grille 112 and to improve the overall integrity. The transition grille 113 does not have the requirement of air outlet or air intake. Therefore, the transition grille 113 is provided with multiple blind holes 1133. The transition grille 113 is constructed as a solid structure, which can protect the structure behind the transition grille 113 and improve the structural stability of the front grille 11.

[0073] In some embodiments of this utility model, such as Figure 3 As shown, the transition grid 113 includes a plurality of third grid bars 1131 arranged in the vertical direction. The rear ends of two adjacent third grid bars 1131 are connected by a sealing grid 1132, thereby defining a blind hole 1133 between two adjacent third grid bars 1131.

[0074] In some embodiments of this utility model, such as Figure 3As shown, the front grille 11 consists of an air intake grille 111, a transition grille 113, and an air outlet grille 112, arranged from top to bottom. The air intake grille 111 includes multiple first grille bars 1111 arranged vertically, the transition grille 113 includes multiple third grille bars 1131 arranged vertically, and the air outlet grille 112 includes multiple second grille bars 1121 arranged vertically. The spacing between the first grille bar 1111 at the bottom of the air intake grille 111 and the third grille bar 1131 at the top of the transition grille 113 is similar to the spacing between two adjacent first grille bars 1111. Similarly, the spacing between the second grille bar 1121 at the top of the air outlet grille 112 and the third grille bar 1131 at the bottom of the transition grille 113 is similar to the spacing between two adjacent second grille bars 1121. This further enhances the overall integrity of the air intake grille 111, transition grille 113, and air outlet grille 112.

[0075] In some embodiments of this utility model, such as Figures 2-4 As shown, the transition grille 113, the air intake grille 111, and the air outlet grille 112 are integrally molded parts. This improves the overall integrity of the front grille 11, and the integral molding of the transition grille 113, air intake grille 111, and air outlet grille 112 also enhances the structural stability of the front grille 11, reduces the swaying caused by airflow impact, and helps to reduce airflow noise.

[0076] In some embodiments of this utility model, such as Figure 3 As shown, the front grille 11 is generally in the shape of an arc plate protruding forward, and the front ends of the transition grille 113, the air intake grille 111 and the air outlet grille 112 are located on the same arc surface M.

[0077] The front grille 11 is an arc-shaped panel that protrudes forward. Compared to designing the front grille 11 as a flat panel, the arc-shaped panel is more rigid, less prone to dents, and less prone to vibration, which helps to improve the structural stability of the front grille 11.

[0078] The front faces of the transition grille 113, the air inlet grille 111, and the air outlet grille 112 are located on the same arc surface M. The front faces of the transition grille 113, the air inlet grille 111, and the air outlet grille 112 do not protrude forward, which can reduce the occupation of the front space, facilitate the arrangement and installation of the air conditioner 100, and improve the overall integrity of the front grille 11.

[0079] In some embodiments of this utility model, such as Figure 2 As shown, the air conditioner 100 also includes a water tray 4 located below the indoor heat exchanger 2, and in the front-rear direction, a transition grille 113 is located in front of the water tray 4 to at least cover the water tray 4.

[0080] The drip tray 4 is used to collect the condensate dripping from the indoor heat exchanger 2. The transition grille 113 is set in front of the drip tray 4, which can protect the drip tray 4 on the rear side, reduce the influence of the external environment on the drip tray 4, and improve the working stability of the drip tray 4.

[0081] In some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, the housing 1 includes a face frame 12, and a front grille 11 is supported on the front side of the face frame 12 by a support member 114. At least the edge of the front grille 11 is spaced apart from the front surface of the face frame 12.

[0082] The support member 114 is located at the edge of the front grille 11, and the front grille 11 is supported on the front side of the face frame 12 by the support member 114. The edge of the front grille 11 is spaced apart from the front surface of the face frame 12, so that the edge of the front frame is not connected to the panel, visually presenting that the front grille 11 is floating relative to the face frame 12, thus enhancing the visual novelty of the air conditioner 100.

[0083] In some embodiments of this utility model, such as Figure 5 As shown, a recessed groove 121 is provided on the front side of the face frame 12, the side wall of the recessed groove 121 extends inward at an angle, and the edge of the front grille 11 is spaced apart from the side wall of the recessed groove 121.

[0084] In some embodiments of this utility model, such as Figure 1 and Figure 4 As shown, the air conditioner 100 also includes a display panel 6, which is located on the front side of the housing 1 and is arranged side by side with the front grille 11.

[0085] By setting a display panel 6 on the front side of the casing 1, the operating information of the air conditioner 100 or indoor temperature information can be displayed intuitively on the display panel 6, thereby improving the functionality of the air conditioner 100.

[0086] By arranging the display panel 6 and the front grille 11 side by side, compared to arranging the display panel 6 and the front grille 11 vertically, the size of the air conditioner 100 in the vertical direction can be reduced, making it easier to arrange the air conditioner 100.

[0087] In some embodiments of this utility model, such as Figure 2 As shown, the air conditioner 100 includes a fan wheel 5, which is located at the air inlet of the air duct assembly 3. The fan wheel 5 drives the external airflow into the casing 1, and after heat exchange in the indoor heat exchanger 2, it flows along the air duct assembly 3.

[0088] In some embodiments of this utility model, such as Figure 2As shown, the top of the casing 1 has an upper air inlet 14. Thus, the air conditioner 100 can not only take in air through the upper air inlet 14, but also through the front air grille 111, which can increase the air intake volume and help improve the heat exchange efficiency of the air conditioner 100.

[0089] In some embodiments of this utility model, such as Figure 7 As shown, the housing 1 includes an upper air intake grille 17 located at the top, which defines an upper air intake 14.

[0090] In some embodiments of this utility model, such as Figure 2 and Figure 7 As shown, the bottom of the housing 1 is provided with a lower air outlet 14, which is located behind the air outlet grille 112. The air conditioner 100 also includes a first air guide plate 71, which is rotatably disposed on the housing 1 to open or block the lower air outlet 14.

[0091] The air conditioner 100 can selectively discharge air through the air outlet grille 112 or through the lower air outlet 14. The lower air outlet 14 is located behind the air outlet grille 112, which can increase the air outlet range of the air conditioner 100 in both the front-to-back and vertical directions. The air outlet method can also be selected according to the operating mode of the air conditioner 100, thereby improving the heat exchange effect of the air conditioner 100. For example, when the air conditioner 100 is heating, it can directly discharge air from the lower air outlet 14, pressing the hot air downwards to improve the situation where hot air accumulates at the top and causes cold air at the bottom, thus improving the heating effect. As another example, when the air conditioner 100 is cooling, it can discharge air through the air outlet grille 112, which can increase the coverage of cold air and improve the cooling efficiency.

[0092] In some embodiments of this utility model, the first air guide plate 71 can be a solid plate, and the first air guide plate 71 has strong structural stability and is not easily deformed.

[0093] In some other embodiments of this utility model, the first air guide plate 71 may be a hollow plate, which makes the first air guide plate 71 lighter and easier to rotate, and the air guiding motion is more flexible.

[0094] In some embodiments of this utility model, such as Figure 7 As shown, the first air guide plate 71 is rotatably mounted on the housing 1 via the rotating part at the rear end. The housing 1 defines a rotation channel 16 on the rear side of the first air guide plate 71. The rotation channel 16 is used to accommodate the rotation range of the first air guide plate 71, which can reduce the motion interference between the first air guide plate 71 and the housing 1.

[0095] In some embodiments of this utility model, such as Figure 5 , Figure 8 and Figure 10As shown, the housing 1 includes a partition 15 located between the lower air outlet 14 and the front grille 11.

[0096] The lower air outlet 14 is located behind the air outlet grille 112, and the partition 15 is located in front of the lower air outlet 14, with at least a portion of the partition 15 located below the front grille 11. By providing the partition 15 between the lower air outlet 14 and the front grille 11, the lower part of the front grille 11 is supported, thereby improving the installation stability of the front grille 11.

[0097] In some embodiments of this utility model, such as Figure 7 and Figure 9 As shown, the air conditioner 100 also includes a second air guide plate 72 rotatably disposed in the housing 1, the second air guide plate 72 being rotatable to deliver air toward the lower air outlet 14 and / or the air outlet grille 112.

[0098] The second air guide plate 72 rotates to direct airflow towards the air outlet grille 112 and / or the lower air outlet 14, which can improve the smoothness of airflow and enhance the heat exchange effect of the air conditioner 100. Not limited to this, the second air guide plate 72 can also rotate to block the air outlet grille 112 as described below, effectively opening and closing the air outlet grille 112, thereby enabling the air conditioner 100 to achieve multiple air supply modes.

[0099] In some embodiments of this utility model, such as Figure 8 and Figure 9 As shown, the air conditioner 100 has a first mode in which the air outlet of the first air guide plate 71 faces downward to open the lower air outlet 14, and the second air guide plate 72 blocks the air outlet grille 112.

[0100] The first air guide plate 71 rotates downwards to open the lower air outlet 14, allowing airflow to exit from the lower air outlet 14. The second air guide plate 72 rotates to block the air outlet grille 112, preventing airflow from exiting from the air outlet grille 112. This ensures that the air conditioner 100 primarily exits air through the lower air outlet 14, guiding the airflow downwards and resulting in a larger outflow volume.

[0101] In the first mode, the air conditioner 100 is suitable for heating. The second air guide plate 72 blocks the air outlet grille 112, and the first air guide plate 71 opens the lower air outlet 14. The air outlet end of the first air guide plate 71 is opened downward to guide the airflow downward, which can push the hot air downward and effectively achieve the effect of blowing the heating airflow downward. This can greatly improve the heating temperature rise and stratification effect, and greatly improve the heating foot warmth and comfort performance.

[0102] In some embodiments of this utility model, the first mode of the air conditioner 100 is a heating and air supply mode.

[0103] In some embodiments of this utility model, such as Figure 6 and Figure 7 As shown, the air conditioner 100 has a second mode. In the second mode, the first air guide plate 71 blocks the lower air outlet 14, and the air outlet end of the second air guide plate 72 is directed toward the air outlet grille 112 to guide the air towards the air outlet grille 112.

[0104] The first air guide plate 71 blocks the lower air outlet 14, so the lower air outlet 14 does not produce air. The air outlet end of the second air guide plate 72 is directed towards the air outlet grille 112 to guide the air. The air conditioner 100 completely discharges air through the air outlet grille 112, and the airflow is sent forward, with a large air volume flowing forward.

[0105] In the second mode, the air conditioner 100 is suitable for cooling. The first air guide plate 71 blocks the lower air outlet 14 to prevent cold air from blowing directly down onto the human body, thereby improving the discomfort caused by cold air blowing directly on the body. Furthermore, the second air guide plate 72 sends the cold air forward from the air outlet grille 112, which can increase the air delivery distance of the cold air in the front-to-back direction and increase the coverage of the cold air.

[0106] In some embodiments of this utility model, the second mode of the air conditioner 100 is a cooling and air supply mode.

[0107] In some embodiments of this utility model, such as Figure 11 As shown, the second air guide plate 72 has a hollow area 721; the air conditioner 100 has a third mode. In the third mode, the air outlet end of the first air guide plate 71 is set downward, the second air guide plate 72 blocks part of the lower air outlet 14, and the second air guide plate 72 and the first air guide plate 71 are spaced apart to define the air outlet channel 73. The air outlet channel 73, the hollow area 721 and the air outlet grille 112 all emit air.

[0108] The second air guide plate 72 has a hollow area 721, through which airflow can pass through the hollow area 721 and pass through the second air guide plate 72, thereby reducing the obstruction of airflow and helping to improve the air outlet range of the air conditioner 100.

[0109] The first air guide plate 71 is set with its air outlet facing downwards, opening the lower air outlet 14 to a larger extent. The second air guide plate 72 partially blocks the lower air outlet 14, and the first air guide plate 71 and the second air guide plate 72 define an air outlet channel 73. The second air guide plate 72 opens the air outlet grille 112, and a hollow area 721 is formed on the second air guide plate 72. Therefore, air outlets are discharged from the air outlet channel 73, the hollow area 721, and the air outlet grille 112. The air outlet channel 73 and the hollow area 721 on the second air guide plate 72 basically cover the area of ​​the lower air outlet 14, thereby increasing the air outlet area of ​​the air conditioner 100.

[0110] The air conditioner 100 has three air outlets. The first air outlet blows forward from the upper side of the second air guide plate 72 through the air outlet grille 112. The second air outlet blows forward and downward along the hollow area 721 on the second air guide plate 72. The third air outlet flows out downward from the air outlet channel 73. The airflow diffuses and flows, covering a large area.

[0111] In the third mode, the air conditioner 100 can be used for both cooling and heating. The air conditioner 100 has the largest air outlet area, which can improve the coverage of the airflow, thus enabling rapid cooling or heating.

[0112] In some embodiments of this utility model, the third mode of the air conditioner 100 is a full air outlet mode.

[0113] In some embodiments of this utility model, such as Figure 11 As shown, the air duct assembly 3 includes a volute 31 to smoothly deliver airflow. The airflow near the volute 31 is larger, while the airflow further away from the volute 31 is smaller. The lower air outlet 14 is located away from the volute 31, so a loop can easily form near the first air guide plate 71 at the lower air outlet 31, resulting in condensation. Therefore, by setting a second air guide plate 72 to form an air outlet channel 73 between the second air guide plate 72 and the first air guide plate 71, the air outlet channel 73 forms a constricted shape. This increases the airflow velocity near the first air guide plate 71, allowing the airflow to flow out quickly from the air outlet channel 73 between the first air guide plate 71 and the second air guide plate 72, reducing backflow and condensation.

[0114] In some embodiments of this utility model, the air conditioner 100 may be a wall-mounted air conditioner.

[0115] Not limited to this, air conditioner 100 can also be a window unit, etc.
