[0036] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0037] Combination Figures 1 to 4 As shown, according to a specific embodiment of the present invention, a housing assembly is provided.

[0038] Specifically, the shell assembly includes a shell 10, a middle channel 20, a fan unit 30 and a drainage tube 40. The shell 10 has a plurality of accommodating chambers, and the plurality of accommodating chambers are arranged at intervals, each accommodating chamber has an air inlet and an air outlet, and a middle channel 20 is arranged between at least two adjacent accommodating chambers among the plurality of accommodating chambers. The middle channel 20 is arranged in communication with one of the accommodating chambers, and a fan unit 30 is arranged in each accommodating chamber. The first end of the drainage tube 40 is arranged in communication with the middle channel 20. The second end of the drainage tube 40 is arranged side by side with the air outlet of one of the plurality of accommodating chambers. Among them, when the fan unit 30 located in the accommodating chamber is in operation, the external airflow enters the shell 10 from the air inlet of each accommodating chamber under the action of the fan unit 30, and then passes through the air outlet of each accommodating chamber and is discharged from the shell 10 from the second end of the drainage tube 40.

[0039] In this embodiment, by arranging a guide tube in the shell, the air supply distance of the fan unit blowing the airflow out of the shell assembly can be increased. Moreover, the guide tube is directly connected to the middle channel 20, and after the airflow flows out of the middle channel 20, it directly flows into the guide tube to realize air supply, and will not flow to other directions, ensuring that part of the air volume will not be lost. Therefore, it is possible to avoid increasing the air supply distance by increasing the speed of the fan motor to increase the air volume, and the air conditioner using the shell assembly of this structure can indirectly reduce the noise of the air conditioner. The shell assembly has a simple structure, is easy to process, and has good stability.

[0040] Specifically, Figure 2 and Figure 3As shown, the housing 10 includes a volute 11 and a volute cover 12. A plurality of accommodating cavities are provided on the first surface of the volute 11 at intervals in the vertical direction. The outlet end of the middle channel 20 is provided on the second surface of the volute 11 opposite to the first surface. The drainage tube 40 is connected to the second surface of the volute 11. The volute cover 12 is connected to the first surface of the volute 11, and the volute cover 12 and the volute 11 are enclosed to form an air inlet channel and an air outlet channel of each accommodating cavity. Such an arrangement can improve the installation stability of the drainage tube 40.

[0041] like Figure 1 As shown, the multiple accommodating chambers include a first accommodating chamber 51 and a second accommodating chamber 52. The first accommodating chamber 51 is located above the second accommodating chamber 52. The middle channel 20 is arranged between the first accommodating chamber 51 and the second accommodating chamber 52 and is connected to the second accommodating chamber 52. A first air outlet 511 is provided at the top of the first accommodating chamber 51. A second air outlet 521 is provided at the bottom of the second accommodating chamber 52, and a third air outlet 42 is formed at the second end of the drainage tube 40, and the third air outlet 42 is arranged flush with the first air outlet 511. This arrangement enables part of the airflow in the second accommodating chamber 52 to be blown out from the direction of the first air outlet 511, effectively increasing the air supply distance at the first air outlet 511 and the third air outlet 42.

[0042] Preferably, the inner wall surface of the drainage tube 40 is a smooth plane structure. Such a setting can reduce the wind resistance of the airflow and reduce the loss of air volume. Among them, the cross-section of the drainage tube 40 is polygonal, elliptical or circular. The connection between the drainage tube 40 and the middle channel 20 is a smooth plane transition setting, and the connection between the drainage tube 40 and the middle channel 20 adopts a stop seal. Such a setting can improve the sealing of the connection between the drainage tube 40 and the middle channel 20. Among them, the drainage tube 40 can adopt a setting method in which the cross-section of the internal air duct outlet end remains unchanged, which can improve the stability of the pressure at the air outlet end and ensure the air supply distance.

[0043] like Figure 2 As shown, the outer surface of the drainage tube 40 is provided with a connecting flange 41, and the drainage tube 40 is connected to the volute 11 through the connecting flange 41. Such a configuration can increase the installation stability of the drainage tube 40.

[0044] like Figure 3 and Figure 4 As shown, the housing assembly further includes a guide cover 60. The guide cover 60 is disposed in the second accommodating cavity 52, and the guide cover 60 is located at the connection between the middle channel 20 and the cavity wall of the second accommodating cavity 52, so as to guide part of the airflow in the second accommodating cavity 52 into the middle channel 20.

[0045] Further, the fan part 30 includes a first fan assembly 31 and a second fan assembly 32. The first fan assembly 31 is arranged in the first accommodating cavity 51. The second fan assembly 32 is arranged in the second accommodating cavity 52. ​​Among them, the profile of the fan blades of the first fan assembly 31 is arranged identically to the profile of the fan blades of the second fan assembly 32. The number of fan blades of the first fan assembly 31 is arranged identically to the number of fan blades of the second fan assembly 32. The axial height of the fan of the first fan assembly 31 is arranged differently from the axial height of the fan of the second fan assembly 32. The diameter of the fan of the first fan assembly 31 is arranged differently from the diameter of the fan of the second fan assembly 32. Preferably, the axial height of the fan of the first fan assembly 31 is 10 mm smaller than the axial height of the fan of the second fan assembly 32. The diameter of the fan of the first fan assembly 31 is 10 mm smaller than the diameter of the fan of the second fan assembly 32 . The number of fan blades of the first fan assembly 31 and the number of fan blades of the second fan assembly 32 are both 72.

[0046] In the prior art, the shell includes a volute cover, the volute cover has two upper and lower air inlets, the volute has two upper and lower accommodating chambers, and the accommodating chambers are arranged corresponding to the two air inlets of the volute cover. The upper accommodating chamber has an upper air outlet, and the lower accommodating chamber has a middle air outlet and a lower air outlet. Among them: the airflow of the upper air outlet and the middle air outlet is transported upward, and the airflow of the lower air outlet is transported downward. The air guide cover is assembled in the middle position of the volute, and is arranged to transitionally connect with the middle air outlet of the volute, so as to guide the airflow sucked in from the lower air inlet of the volute cover to the middle air outlet of the volute. The prior art also includes an upper fan assembly and a lower fan assembly. The upper fan assembly is installed in the upper accommodating chamber of the volute, and when the upper centrifugal fan blade is in operation, it can suck the airflow from the air inlet on the volute cover and send it to the upper air outlet. Similarly, the lower fan assembly is installed in the lower end accommodating chamber of the volute. A part of the airflow flows out from the lower air outlet under the action of the lower centrifugal fan, and the other part of the airflow flows out from the middle air outlet through the air guide cover. The volute cover, volute, air guide cover, upper fan assembly, and lower fan assembly together constitute the air duct component. In the prior art, the shell assembly also includes a windshield, and the windshield cover is arranged on the volute. The two sides of the windshield and the two sides of the volute are respectively fastened and sealed by screws. After the volute and the windshield are assembled, an internal air cavity is formed, and the airflow can flow in the internal air cavity.

[0047] The following problems exist in the shell assembly of the prior art:

[0048] Inside the air duct, the section above the middle air outlet is the upper cavity space formed by the volute and the wind shield. The high-speed airflow flowing out of the middle air outlet enters the upper space, and the cross-section through which the airflow passes suddenly increases, resulting in a slow flow rate and insufficient subsequent air supply distance. At the same time, the upper half of the volute and the upper half of the wind shield contained in the upper cavity are designed with many protruding or recessed structures due to structural functions and assembly requirements, resulting in the path of the airflow not being smooth enough, and many small vortices are easily formed in this space, causing the air volume to decay. In addition, since the cavity formed by the volute and the wind shield is relatively long, most of the airflow blown out from the middle air outlet will not only pass through the upper cavity, but also some of the airflow will flow to the left and right ends of the middle air outlet, and flow downward. This part of the air volume cannot play a role in supplying air to the whole machine, and part of the air volume will also be lost. Therefore, the structural layout of the prior art will lead to air volume loss. In order to ensure that the air volume of the whole machine meets the standard, the motor speed of the fan blade is usually increased, which leads to increased noise.

[0049] In order to solve the technical problems existing in the prior art, the present application provides a shell component with a new structure. When the shell component of the present application is adopted, the air volume and the cross-section through which the airflow flows will not suddenly increase compared with before, and the airflow velocity will not have a large mutation, so the air supply distance can be guaranteed. After the airflow flows out from the air outlet end of the middle channel 20, it directly flows into the drainage tube, and the flow path is smooth and smooth, and there will be no obvious air volume attenuation due to the obstruction of various concave and convex structures. The drainage tube structure is directly connected to the middle air outlet. After the airflow flows out from the middle air outlet, it directly flows into the drainage tube to supply air upward, and will not flow in other directions, ensuring that part of the air volume will not be lost. Therefore, the method of increasing the speed of the fan motor to increase the air volume can be avoided, and the noise is indirectly reduced.

[0050] In another embodiment of the present application, the shell assembly includes a volute cover, the volute cover includes two air inlets, one upper and one lower, and the volute has two upper and lower accommodating chambers, and the accommodating chambers are arranged corresponding to the two air inlets of the volute cover. The upper accommodating chamber has an upper air outlet, and the lower accommodating chamber has a middle air outlet and a lower air outlet. Among them: the airflow of the upper air outlet and the middle air outlet is transported upward, and the airflow of the lower air outlet is transported downward. The guide cover is arranged in the middle position of the volute and transitionally connected with the middle air outlet of the volute. In the air duct structure formed by the lower accommodating chamber, when part of the airflow is generated and sent out from the lower accommodating chamber, it first passes through the guide cover to guide the airflow to the middle channel 20. The upper fan assembly includes an upper mounting plate, a DC motor, a motor bracket, a centrifugal fan blade, a stop gasket, and a nut with a pad. The upper fan assembly is installed in the upper accommodating chamber of the volute as a whole, and the DC motor drives the fan blade to rotate after power is turned on.

[0051] The lower fan assembly includes a lower mounting plate, a DC motor, a motor bracket, a centrifugal fan blade, a rotation-stopping gasket, and a nut with a gasket; the lower fan assembly is installed as a whole in the lower accommodating chamber of the volute, and the DC motor drives the fan blade to rotate after power is turned on. The drainage tube is arranged in the upper half of the cavity space formed by the volute and the wind shield. The lower end of the drainage tube is transitionally connected with the middle air outlet of the volute, and the two adopt a bent stop at the transition port, and the two can fit together for sealing. The upper end of the drainage tube is designed as a straight tube, and the straight tube air outlet is facing upward, and the end of the air outlet is flush with the end of the upper air outlet of the volute.

[0052] Specifically, the two sides of the drainage tube can be fixed to the volute by six screws. The wind shield 13 is covered on the volute, and the two sides of the wind shield and the two sides of the volute are respectively fastened and sealed by screws. That is, a drainage tube is added to the upper half of the cavity space formed by the volute and the wind shield.

[0053] Specifically, the housing assembly includes a volute cover, which includes two air inlets, one on the upper side and one on the lower side; the air inlets are both circular, and when the air duct is working, air enters the upper and lower accommodating chambers from the two air inlets. The volute includes two accommodating chambers, one on the upper side and one on the lower side, and the upper accommodating chamber has an upper air outlet facing upward. When the air conditioner is running, the air outlet of the upper accommodating chamber faces the head of the air conditioner and is blown out from the top of the housing assembly.

[0054] The lower accommodating chamber has an upward middle air outlet (i.e., the outlet end of the middle channel 20) and a downward lower air outlet. The air volume of the middle air outlet of the lower accommodating chamber is blown upward, and the airflow is guided to the air conditioner head through the guide tube and blown out from the air conditioner head. The volute profiles of the two upper and lower accommodating chambers can be the same or different. The air guide cover is arranged in the middle position of the volute and transitionally connected with the middle air outlet of the volute. In the air duct structure formed by the lower accommodating chamber, when the airflow is generated and sent out from the lower accommodating chamber, a part of it is guided by the air guide cover and sent to the middle air outlet, and the other part of the airflow will be sent out from the lower air outlet. The upper fan assembly includes an upper mounting plate, an upper DC motor, a motor bracket, an upper centrifugal fan blade, a stop gasket, and a nut with a pad. The upper fan assembly is installed in the upper accommodating chamber of the volute as a whole. After power is turned on, the DC motor drives the fan blade to rotate. The lower fan assembly includes a lower mounting plate, a lower DC motor, a motor bracket, a lower centrifugal fan blade, a rotation-stopping gasket, and a nut with a gasket; the lower fan assembly is installed as a whole in the lower accommodating chamber of the volute, and the DC motor drives the fan blade to rotate after power is turned on. The difference between the upper centrifugal fan and the lower centrifugal fan is that the profiles of the two centrifugal fan blades are the same, wherein the profiles of the blades are wing-like, and the number of blades is seventy-two. However, the heights and diameters of the two fans are different, and the diameter of the lower centrifugal fan is 10 mm larger than that of the upper centrifugal fan, and the height is 10 mm higher than that of the upper centrifugal fan.

[0055] The drainage tube includes a transition part and a straight pipe part. The transition part contains an air inlet, and the air inlet is installed and connected opposite to the middle air outlet of the volute. A bending stop is arranged around the air inlet of the transition part, which can be connected and matched with the bending stop at the middle air outlet of the volute to play a sealing role. The two sides of the drainage tube are fixed to the two sides of the volute by screwing. The air outlet at the upper end of the drainage tube is flush with the air outlet on the volute. The wind shield 13 is covered on the volute, and the two sides of the wind shield are respectively fastened and sealed to the two sides of the volute by screws.

[0056] In the present application, the drainage tube 40 and the middle channel 20 can be integrally arranged, and the cross-sectional area of ​​the air duct of the drainage tube 40 is set differently from the cross-sectional area of ​​the air duct of the middle channel 20. Specifically, the cross-sectional area of ​​the air duct of the drainage tube 40 is set uniformly along the air outlet direction of the drainage tube 40, and the cross-sectional area of ​​the air duct of the middle channel 20 is set gradually increasing along the air outlet direction of the middle channel 20. Such an arrangement can improve the stability of air supply of the drainage tube 40.
