[0002] While all embedded air conditioner indoor units (such as kitchen air conditioners) generate some noise during operation, the smaller the size of the embedded air conditioner indoor unit, the greater the noise it produces. Therefore, how to better reduce the noise generated by small-sized embedded air conditioner indoor units during operation is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0003] Analysis and research have found that the smaller the size of the embedded air conditioner indoor unit, the smaller the distance between the air outlet of the fan assembly and the heat exchanger.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention 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.

[0033] The embedded air conditioner indoor unit provided in this embodiment of the invention, such as Figures 1 to 6 As shown, it includes: a main body 100, the interior of which has a first air duct 110 and a second air duct 120; a heat exchanger 200, which is disposed within the first air duct 110; and a fan assembly 300, the first air outlet 310 of the fan assembly 300 being connected to the first air duct 110, the second air outlet 350 of the fan assembly 300 being connected to the second air duct 120, and the fan assembly 300 being configured to form an airflow from the second air duct 120 through the fan assembly 300 to the first air duct 110; wherein, the first air outlet 310 is provided with a noise reduction structure 311, the noise reduction structure 311 being configured to block the airflow from blowing onto the fin noise generation area formed on the heat exchanger 200 during the operation of the fan assembly 300, so as to reduce the sound of the airflow blowing on the fins generated in the fin noise generation area during the operation of the fan assembly 300.

[0034] In this embedded air conditioner indoor unit, the first air outlet 310 is equipped with a noise reduction structure 311. During the operation of the fan assembly 300, the noise reduction structure 311 blocks the airflow from blowing towards the fin noise generation area, thereby reducing or even eliminating the sound of the airflow blowing on the fin noise generation area. Therefore, this embedded air conditioner indoor unit generates less noise during operation. The first air outlet 310 is configured as an air outlet, and the second air outlet 350 is configured as an air inlet.

[0035] In some examples, such as Figures 1 to 4 As shown, the noise improvement structure 311 is a wind deflector, which is fixed inside the first air outlet 310 and positioned opposite to the fin noise generation area. The wind deflector blocks the airflow blown from the first air outlet 310 to the fin noise generation area, reducing the air volume and speed of the airflow. This makes it less likely for the fin noise generation area to generate the sound of airflow blowing against the fins during the operation of the fan assembly 300, thus reducing the noise generated during the operation of the embedded air conditioner indoor unit. The distance J between the end wall of the first air outlet 310 and the wind deflector in the axial direction of the fan assembly 300 is generally not less than 15mm.

[0036] The windbreak rib can be a straight rib; or it can be a curved rib, which can be an arc-shaped rib or a folded rib, etc.; both of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this invention, so they will not be repeated here, and all should fall within the protection scope of this application.

[0037] In some embodiments, such as Figure 4 As shown, the width K of the wind deflector rib in the axial direction of the fan assembly 300 is not less than 6mm. This improves the blocking effect of the wind deflector rib on the airflow blowing from the first air outlet 310 to the fin noise generation area, making it less likely for the fin noise generation area to generate the sound of the airflow blowing against the fins during the operation of the fan assembly 300. Alternatively, the width of the wind deflector rib in the axial direction of the fan assembly 300 can be set to 6mm; or it can be set to 7mm; or it can be set to 8mm, etc. All of these can achieve the purpose of this application, and their intent does not depart from the design concept of this invention. Therefore, they will not be elaborated further and should all fall within the protection scope of this application.

[0038] Under the same air volume, the noise generated by the embedded air conditioner indoor unit provided in this application is reduced by approximately 2 dB.

[0039] In some exemplary embodiments, such as Figures 2 to 4As shown, the first air outlet 310 is also provided with an air guide structure 312. The air guide structure 312 is configured to guide the air jet to different positions on the side of the heat exchanger 200 facing the first air outlet 310, so as to better achieve the optimal heat exchange performance at different positions on the heat exchanger 200.

[0040] In some examples, such as Figure 1 As shown, the fan assembly 300 is arranged horizontally along its axis. The first air outlet 310 is inclined upward from one end adjacent to the heat exchanger 200 to the end away from the heat exchanger 200. The long side of the first air outlet 310 adjacent to the heat exchanger 200 is arranged horizontally, and the wide side is inclined upward from bottom to top toward the side where the heat exchanger 200 is located. The air guide structure 312 includes an air guide plate, which is inclined upward from one end adjacent to the heat exchanger 200 to the end away from the heat exchanger 200. The heat exchanger 200 is inclined downward from top to bottom toward the side where the fan assembly 300 is located.

[0041] It can be, such as Figure 2 and Figure 3 As shown, the air guide plate can be a straight plate; or it can be a curved plate, which can be an arc plate or a folded plate, etc.; all of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this invention. They will not be described in detail here, and all should fall within the protection scope of this application.

[0042] Among them, such as Figures 2 to 4 As shown, there are multiple windbreak ribs arranged sequentially in the vertical direction and separated by air guide plates. The air guide plates are connected to the windbreak ribs above and below them. The uppermost windbreak rib is connected to the upper wall of the first air outlet 310, and the lowermost windbreak rib is connected to the lower wall of the first air outlet 310, thus increasing the structural strength of the windbreak ribs.

[0043] It could be that if there is only one wind deflector, then there are two wind deflector ribs; or it could be, for example... Figures 2 to 4 As shown, if there are two wind deflectors, then there are three wind deflector ribs; or if there are three wind deflectors, then there are four wind deflector ribs, etc.; all of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this invention, so they will not be repeated here, and all should fall within the protection scope of this application.

[0044] In some embodiments, such as Figures 2 to 5 As shown, the air guide vanes include N vanes spaced vertically at intervals, where N ≥ 2. The tilt angle of the i-th air guide vane from top to bottom relative to the horizontal plane is K. i Where i is a positive integer ranging from 1 to N, the inclination angle of the lower wall of the first air outlet 310 relative to the horizontal plane is M, and A1 is the width of the end of the first air outlet 310 adjacent to the heat exchanger 200. In the vertical direction:

[0045] The vertical distance B1 between the lower end of the first air guide plate and the upper wall of the first air outlet 310 is B1 = A1 / [(N+1)*Sin(90°-K)]. i The width of the first air guide plate is C1 = B1 / Sin(K). i ), at this time i = 1;

[0046] The vertical distance B between the lower end of the i-th air guide plate and the lower end of the (i-1)-th air guide plate i =A1 / [(N+1)*Sin(90°-K)] i The width C of the i-th air guide plate i =B i / Sin(K i ), where i = 2 ~ N;

[0047] The vertical distance B between the lower end of the last air guide plate and the lower wall of the first air outlet 310 末 =A1 / [(N+1)*Sin(90°-M)].

[0048] It is possible to set B1 to 30mm-70mm and C1 to 10mm-40mm. It is possible to set B... i Set to 30mm~70mm, C i Set to 10mm~40mm; if N is 2, then B i Including B2, C i Including C2; if N is 3, then B i Including B2 and B3, C i Includes C2 and C3; if N is 3, then B i Including B2, B3, and B4, C i Includes C2, C3, and C4; it could be B. 末 Set to 30mm~70mm. Alternatively, the shortest distance C3 between adjacent air guide vanes can be set to be equal to C1.

[0049] In one embodiment, such as Figure 5 As shown, N=2, then K1=K2≈M≈A, or K1+A=90°, where A is the tilt angle of heat exchanger 200 relative to the horizontal plane.

[0050] In some exemplary embodiments, such as Figures 2 to 4 As shown, the first air outlet 310 is also provided with a reinforcing structure 313, which is designed to enhance the structural strength of the air guide structure 312, so that the air guide structure 312 is less likely to be damaged during transportation and use.

[0051] In some examples, such as Figures 2 to 4As shown, the reinforcing structure 313 is a reinforcing rib. The reinforcing rib is vertically arranged along the air outlet direction of the first air outlet 310, and the thickness Q of the reinforcing rib in the axial direction of the fan assembly 300 is not less than 2mm. In this way, the reinforcing rib can better improve the structural strength of the air guide plate.

[0052] Among them, such as Figures 2 to 4 As shown, the reinforcing ribs include multiple ribs arranged sequentially in the vertical direction and separated in the vertical direction by air guide plates. The air guide plates are connected to the upper and lower adjacent reinforcing ribs. The upper end of the uppermost reinforcing rib is connected to the upper wall of the first air outlet 310, and the lower end of the lowermost reinforcing rib is connected to the lower wall of the first air outlet 310.

[0053] It could be that if there is one wind deflector, then there are two reinforcing ribs; or it could be, as... Figures 2 to 4 As shown, if there are two wind deflectors, then there are three reinforcing ribs; or if there are three wind deflectors, then there are four reinforcing ribs, etc.; all of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this invention, so they will not be repeated here, and should all fall within the protection scope of this application.

[0054] In some exemplary embodiments, such as Figures 1 to 6 As shown, the fan assembly 300 includes: a volute body located within the second air duct 120 and having a second air outlet 350 and a third air outlet 331, the second air outlet 350 being located on the end wall of the volute body and the third air outlet 331 being located on the peripheral wall of the volute body; an air outlet frame 360 ​​having a first air outlet 310 located within the first air duct 110 and positioned at the third air outlet 331; and a fan wheel 340 (e.g., Figure 6 As shown), the impeller 340 is housed within the volute body; and the motor (as shown) Figure 6 As shown, the motor is located outside the volute body and connected to the impeller 340. The motor is configured to drive the impeller 340 to rotate.

[0055] In some examples, such as Figure 2 As shown, the volute body includes a first housing 320 at the bottom and a second housing 330 at the top. The first housing 320 and the second housing 330 are assembled together to form a second air outlet 350. The fan assembly 300 also includes a partition 400, which is located inside the main body 100 and divides the interior of the main body 100 into a first air duct 110 and a second air duct 120. The second housing 330 and the partition 400 are an integral structure. The third air outlet 331 is located between the partition 400 and the second housing 330. Compared with a technical solution where the second housing 330 and the partition 400 are separate structures, this solution can effectively improve the assembly efficiency of the fan assembly 300.

[0056] Among them, such as Figure 4 and Figure 6 As shown, along the axial direction of the volute body (i.e., the axial direction of the impeller 340), mounting plates 361 are provided at both ends of the air outlet frame 360. The mounting plates 361 are placed on the partition 400 outside the third air outlet 331 and are fixedly connected to the partition 400. Along the axial direction of the volute body: the width of the mounting plate 361 is Y, the length of the impeller 340 is G, the length L of the air outlet frame 360 ​​is set to G + (10~20) mm, and the length M of the volute body is set to G + (120~150) mm. Preferably, G can be set to 160 mm~220 mm, and the distance P between the reinforcing rib and the frame edge of the air outlet frame 360 ​​along the axial direction of the volute body is set to 40 mm~70 mm.

[0057] When the size L is relatively large, multiple sets of reinforcing ribs (not shown in the diagram) can be spaced apart along the axial direction of the volute body within the first air inlet 310. The distance between adjacent sets of reinforcing ribs is set to 60mm to 100mm, thus increasing the structural strength of the air guide plate. Figure 6 As shown, along the axial direction of the volute body, the distance between one end of the heat exchanger 200 and the wall of the third air vent 331 on the second housing 330 is E, and the distance between the other end of the heat exchanger 200 and the wall of the third air vent 331 on the second housing 330 is F. When E≠F, the noise generated in the fin noise generation area during the operation of the fan assembly 300 is louder. Therefore, E=F is preferred. H is the axial length of the heat exchanger 200 along the volute body.

[0058] The air conditioner proposed in this embodiment of the invention (not shown in the figure) includes an outdoor unit and an embedded indoor unit as described in any of the above embodiments, and the outdoor unit and the embedded indoor unit are used together.

[0059] This air conditioner possesses all the advantages of the embedded air conditioner indoor unit provided in any of the above embodiments, which will not be elaborated here.

[0060] In one embodiment, the air conditioner is configured as a kitchen air conditioner.

[0061] In summary, the embedded air conditioner indoor unit provided in this embodiment of the invention has a noise reduction structure at the first air outlet. During the operation of the fan assembly, the noise reduction structure blocks the airflow from blowing towards the fin noise generation area, thereby reducing or even eliminating the sound of the airflow blowing on the fin noise generation area. Therefore, this solution results in less noise generated during the operation of the embedded air conditioner indoor unit.
