[0004] In some exemplary embodiments, both the first mating surface and the second mating surface are inclined surfaces, and both inclined surfaces slope downwards and forwards.

[0005] In some exemplary embodiments, the inclination angle A of the inclined plane tilting from top to bottom and forward satisfies: 10 degrees ≤ A ≤ 80 degrees.

[0006] In some exemplary embodiments, the upper part of the rear side of the first air guide plate is smoothly connected to the upper end of the first mating surface, and the front end of the upper side of the second air guide plate is smoothly connected to the upper end of the second mating surface.

[0015] The technical solution provided in this application embodiment has a first air outlet at the lower part of the front sidewall of the unit and a second air outlet at the front part of the lower sidewall of the unit.

The first mating surface and the second mating surface are opposite each other, and the projection of the first mating surface in the horizontal direction and the projection of the second mating surface in the horizontal direction at least partially overlap. This makes it less likely for dust to enter the interior of the machine through the gap between the front end face of the second air guide plate and the lower part of the rear side of the first air guide plate. Moreover, when the user observes the machine from bottom to top, the interior of the machine will not be visible through the gap between the front end face of the second air guide plate and the lower part of the rear side of the first air guide plate.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0021] The air conditioner indoor unit provided in this application embodiment, such as Figure 1 , Figure 2 and Figure 4As shown, it includes: a body 100, the lower part of its front sidewall has a first air outlet 110, the front part of its lower sidewall has a second air outlet 120, the lower part of the first air outlet 110 and the front part of the second air outlet 120 are connected; a first air guide plate 200, the first air guide plate 200 is swayably disposed at the first air outlet 110, the lower part of the rear side of the first air guide plate 200 includes a first mating surface 210; and a second air guide plate 300, the second air guide plate 300 is located at the lower rear side of the first air guide plate 200 and is swayably disposed at the second air outlet 120, the front end surface of the second air guide plate 300 includes a second mating surface 310. Based on the first air guide plate 200 being located in the first position and the second air guide plate 300 being located in the second position, the first air guide plate 200 closes the first air outlet 110 and the second air guide plate 300 closes the second air outlet 120. At this time, the first mating surface 210 and the second mating surface 310 are opposite to each other, and the projection of the first mating surface 210 in the horizontal direction and the projection of the second mating surface 310 in the horizontal direction at least partially overlap.

[0022] The lower part of the front sidewall of the unit 100 has a first air outlet 110, and the front part of the lower sidewall of the unit 100 has a second air outlet 120. The lower part of the first air outlet 110 and the front part of the second air outlet 120 are connected. A first air guide plate 200 is swayably disposed at the first air outlet 110, and a second air guide plate 300 is located at the lower rear side of the first air guide plate 200 and is swayably disposed at the second air outlet 120. This design guides the airflow from the first air outlet 110 through the first air guide plate 200 and guides the airflow from the second air outlet 120 through the second air guide plate 300. This results in a larger airflow range for the unit 100 and faster indoor cooling. Furthermore, the lower rear side of the first air guide plate 200 includes a first mating surface 210, and the front of the second air guide plate 300... The end face includes a second mating surface 310. When the first air guide plate 200 is in the first position and the second air guide plate 300 is in the second position, the first air guide plate 200 closes the first air outlet 110 and the second air guide plate 300 closes the second air outlet 120. At this time, the first mating surface 210 and the second mating surface 310 are opposite each other. The projection of the first mating surface 210 in the horizontal direction and the projection of the second mating surface 310 in the horizontal direction at least partially overlap. In this way, dust is less likely to enter the interior of the body 100 through the gap between the front end face of the second air guide plate 300 and the lower part of the rear side of the first air guide plate 200. Moreover, when the user observes the body 100 from bottom to top, the interior of the body 100 will not be seen through the gap between the front end face of the second air guide plate 300 and the lower part of the rear side of the first air guide plate 200.

[0023] In some examples, such as Figure 1 , Figure 2 and Figure 4As shown, both the first mating surface 210 and the second mating surface 310 are inclined surfaces, and both inclined surfaces slope downwards and forwards. When the first air guide plate 200 opens the first air outlet 110 (not shown in the figure, e.g., the upper end of the first air guide plate 200 swings backwards and the lower end of the first air guide plate 200 swings forwards), the cold air inside the body 100, blowing from the upper end of the first air guide plate 200 along the rear side of the first air guide plate 200 towards the front and downwards at the first air outlet 110, will turn at the smooth transition connection between the rear end and the first mating surface 210 and blow towards the front and downwards along the first mating surface 210. For example... Figure 3 As shown, the second air guide plate 300 opens the second air outlet 120 (such as the rear end of the second air guide plate 300 swinging upward and the front end of the second air guide plate 300 swinging downward). The cold air inside the unit 100 is blown forward from the rear end of the second air guide plate 300 at the second air outlet 120 along the upper side and the lower side of the second air guide plate 300, and finally blown into the room. Because the second mating surface 310 is an inclined surface sloping from top to bottom and forward, due to the Coanda effect, the cold air inside the body 100, as it is blown forward from the rear end of the second air guide plate 300 along the upper side of the second air guide plate 300 at the second air outlet 120, will turn at the front end of the second air guide plate 300 and blow forward and downward along the second mating surface 310. This will reduce or even eliminate the warm air recirculation zone 340 at the front end of the second air guide plate 300 (if the front end of the second air guide plate 300 is a vertical surface arranged in the up and down direction, the warm air recirculation zone 340 formed at the front end of the second air guide plate 300 will be the largest, and condensation will easily occur at the front end of the second air guide plate 300). Therefore, condensation is less likely to occur at the front end of the second air guide plate 300.

[0024] In some embodiments, such as Figure 2 As shown, the inclination angle A of the inclined plane tilting from top to bottom and forward satisfies: 10 degrees ≤ A ≤ 80 degrees. This can be achieved by setting the inclination angle A to 10 degrees; or by setting the inclination angle A to 45 degrees; or by setting the inclination angle A to 80 degrees, etc. All of these can achieve the purpose of this application, and their intent does not depart from the design concept of this utility model. Therefore, they will not be elaborated further and should all fall within the protection scope of this application.

[0025] Alternatively, the first mating surface 210 can be configured as a curved surface that is concave forward or convex backward; or the second mating surface 310 can be configured as a curved surface that is convex forward; or both the first mating surface 210 and the second mating surface 310 can be configured as curved surfaces, etc. All of the above can achieve the purpose of this application, and their purpose has not deviated from the design concept of this utility model. They will not be elaborated here, and all should fall within the protection scope of this application.

[0026] In some examples, such as Figure 2 and Figure 4 As shown, the rear side of the first air guide plate 200 also includes a main rear end 220, which is located above the first mating surface 210. The lower end of the main rear end 220 is smoothly connected to the upper end of the first mating surface 210. When the first air guide plate 200 (such as when the lower end of the first air guide plate 200 swings forward) opens the first air outlet 110, the cold air inside the body 100 is more likely to be turned at the position where the main rear end 220 and the first mating surface 210 are smoothly connected and blown forward and downward along the first mating surface 210. The front end of the upper side of the second air guide plate 300 is smoothly connected to the upper end of the second mating surface 310. In this way, when the cold air inside the body 100 is blown forward from the rear end of the second air guide plate 300 at the second air outlet 120 along the upper side of the second air guide plate 300, it is easier for the front end of the second air guide plate 300 to turn and blow forward and downward along the second mating surface 310. The front end of the second air guide plate 300 is less prone to condensation.

[0027] In some examples, such as Figure 1 and Figure 2 As shown, the lower part of the rear side of the first air guide plate 200 also includes a first extension surface 230. The first extension surface 230 is located below the first mating surface 210. The upper end of the first extension surface 230 smoothly transitions to the lower end of the first mating surface 210. The lower end of the first extension surface 230 is lower than the lower side of the second air guide plate 300 and smoothly transitions to the rear end of the lower end surface of the first air guide plate 200. With this design, when the user observes the indoor unit of the air conditioner from front to back, the first air guide plate 200 completely covers the second air guide plate 300, making the second air guide plate 300 invisible and thus making the indoor unit of the air conditioner more aesthetically pleasing.

[0028] In some embodiments, such as Figure 2 As shown, the height B of the first extension surface 230 satisfies: 1mm ≤ C ≤ 5mm. The height B of the first extension surface 230 can be set to 1mm; or it can be set to 3mm; or it can be set to 5mm, etc.; all of the above can achieve the purpose of this application, and their intent does not depart from the design concept of this utility model, and will not be elaborated further here, all of which should fall within the protection scope of this application.

[0029] In some embodiments, such as Figure 2As shown, the distance C between the lower end of the first extension surface 230 and the lower side surface of the second air guide plate 300 satisfies: 0 < C ≤ 3 mm. This distance C can be set to 1 mm; or it can be set to 2 mm; or it can be set to 3 mm, etc. All of these can achieve the purpose of this application, and their intent does not depart from the design concept of this utility model. Therefore, they will not be elaborated further and should all fall within the protection scope of this application.

[0030] In some examples, such as Figure 2 and Figure 3 As shown, the front end face of the second air guide plate 300 also includes a second extension surface 320. The second extension surface 320 is located below the second mating surface 310 and opposite to the first extension surface 230. The upper end of the second extension surface 320 is smoothly connected to the lower end of the second mating surface 310, and the lower end of the second extension surface 320 is smoothly connected to the front end of the lower side of the second air guide plate 300. Both the first extension surface 230 and the second extension surface 320 are straight surfaces arranged in the vertical direction. This way, when a user observes the machine body 100 from below, they will not be able to see the interior of the machine body 100 through the gap between the front end face of the second air guide plate 300 and the lower part of the rear side of the first air guide plate 200. Dust is also less likely to enter the interior of the machine body 100 through the gap between the front end face of the second air guide plate 300 and the lower part of the rear side of the first air guide plate 200.

[0031] In some embodiments, such as Figure 4 As shown, the minimum distance 'a' between the lower part of the rear side of the first air guide plate 200 and the front end face of the second air guide plate 300 satisfies: 0 < a ≤ 4 mm. This distance can be 1 mm; 2 mm; 3 mm; or 4 mm, etc. All of these can achieve the purpose of this application, and their intent does not depart from the design concept of this utility model. Therefore, they will not be elaborated further here, and all should fall within the protection scope of this application.

[0032] In some examples, such as Figure 1 , Figure 2 and Figure 4As shown, a first hinge seat 240 is provided on the upper part of the rear side of the first air guide plate 200. The first hinge seat 240 is hinged to the body 100, so that the first air guide plate 200 can be swayed and positioned at the first air outlet 110. The first hinge seat 240 includes two symmetrically arranged in the left-right direction.

[0033] In some examples, such as Figures 1 to 4 As shown, a second hinge seat 330 is provided at the front of the upper side of the second air guide plate 300. The second hinge seat 330 is hinged to the body 100, so that the second air guide plate 300 can be swayed and positioned at the second air outlet 120. The second hinge seat 330 includes two symmetrically arranged in the left-right direction.

[0034] In some embodiments, such as Figure 1 As shown, the indoor unit of the air conditioner is a wall-mounted unit.

[0035] The air conditioner provided in this application embodiment (not shown in the figure) includes the indoor unit of the air conditioner described in any of the above embodiments.

[0036] This air conditioner possesses all the advantages of the indoor unit provided in any of the above embodiments, which will not be elaborated further here.

[0037] In summary, the technical solution provided by this application embodiment has a first air outlet at the lower part of the front sidewall of the unit and a second air outlet at the front part of the lower sidewall of the unit. The lower part of the first air outlet and the front part of the second air outlet are connected. A first air guide plate is swayably disposed at the first air outlet, and a second air guide plate is located at the lower rear side of the first air guide plate and swayably disposed at the second air outlet. This solution guides the airflow from the first air outlet through the first air guide plate and guides the airflow from the second air outlet through the second air guide plate. This results in a larger airflow range for the unit and faster indoor cooling. Furthermore, the lower rear side of the first air guide plate includes a first mating... The front end face of the second air guide plate includes a second mating surface. When the first air guide plate is in the first position and the second air guide plate is in the second position, the first air guide plate closes the first air outlet and the second air guide plate closes the second air outlet. The first mating surface and the second mating surface are opposite each other, and the projection of the first mating surface in the horizontal direction and the projection of the second mating surface in the horizontal direction at least partially overlap. This makes it less likely for dust to enter the interior of the machine through the gap between the front end face of the second air guide plate and the lower part of the rear side of the first air guide plate. Moreover, when the user observes the machine from bottom to top, the interior of the machine will not be visible through the gap between the front end face of the second air guide plate and the lower part of the rear side of the first air guide plate.
