[0028] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.

[0029] The air conditioner 100 of this embodiment includes a housing 1, a fan box 2, a first fan 31, and a second fan 32. The housing 1 has a chamber 11, and the housing 1 is provided with an air inlet 12 and an air outlet 13, both of which communicate with the chamber 11. The air inlet 12 is located in the length direction of the housing 1 (e.g., along the length of the housing 1). Figure 1 At least one end of the bellows (in the left-right direction shown). The bellows 2 is located inside the chamber 11. The two ends of the bellows 2 along the length of the shell 1 are the first inlet 21 and the second inlet 22, respectively. The bellows 2 is also provided with an outlet 23 that communicates with the air outlet 13. The first fan 31 and the second fan 32 are located inside the bellows 2. The first fan 31 is adjacent to the first inlet 21, and the second fan 32 is adjacent to the second inlet 22.

[0030] Specifically, such as Figures 1-4 As shown, the air inlet 12 is located at the left end of the housing 1, or at the right end of the housing 1, or at both the left and right ends of the housing 1. The air outlet 13 is located at the upper end of the housing 1, or at the lower end of the housing 1, or at both the upper and lower ends of the housing 1. The first inlet 21 is located at the left end of the bellows 2, the second inlet 22 is located at the right end of the bellows 2, and the outlet 23 is located at the front end of the bellows 2. The first inlet 21 and the second inlet 22 are connected to the air inlet 12, and the outlet 23 is connected to the air outlet 13.

[0031] The external air flow can enter the chamber 11 through the air inlet 12. Under the action of the first fan 31 and the second fan 32, the air flow in the chamber 11 enters the air bellow 2 from the first inlet 21 and the second inlet 22 at both ends of the air bellow 2 and is blown to the outlet 23 of the air bellow 2, and is discharged through the air outlet 13.

[0032] The air conditioner 100 of the embodiment of the present disclosure, by arranging the air bellow 2 in the air bellow 2, the two ends of the air bellow 2 in the length direction of the shell 1 are respectively the first inlet 21 and the second inlet 22, so that the air flow entering the chamber 11 through the air inlet 12 can enter the air bellow 2 through the first inlet 21 and the second inlet 22 at the same time, which significantly increases the air inlet amount. Since the first fan 31 is adjacent to the first inlet 21 and the second fan 32 is adjacent to the second inlet 22, the air flow in the air bellow 2 is blown to the outlet 23 faster under the action of the first fan 31 and the second fan 32, which accelerates the air flow speed, so that the air conditioner 100 has better air outlet effect while increasing the air volume, thereby improving the user experience.

[0033] In some embodiments, the air conditioner 100 further comprises a partition plate 4, the partition plate 4 divides the internal space of the air bellow 2 into a first air duct 24 and a second air duct 25 arranged at intervals in the length direction of the shell 1, the first fan 31 is arranged in the first air duct 24, the second fan 32 is arranged in the second air duct 25, and the outlet 23 comprises a first outlet 231 and a second outlet 232, the first outlet 231 is in communication with the first air duct 24 and the air outlet 13, and the second outlet 232 is in communication with the second air duct 25 and the air outlet 13.

[0034] Specifically, as shown in Figures 2-4 The partition plate 4 is arranged in the air bellow 2 and located between the first inlet 21 and the second inlet 22, the partition plate 4 divides the internal space of the air bellow 2 into a first air duct 24 and a second air duct 25 arranged at intervals in the left-right direction, the first air duct 24 is located on the left side, the second air duct 25 is located on the right side, the first outlet 231 is located on the left side, and the second outlet 232 is located on the right side. The air flow entering the first air duct 24 through the first inlet 21 is discharged through the first outlet 231 and the air outlet 13, and the air flow entering the second air duct 25 through the second inlet 22 is discharged through the second outlet 232 and the air outlet 13.

[0035] By dividing the internal space of the air bellow 2 by the partition plate 4, the air flow entering the first air duct 24 of the air bellow 2 through the first inlet 21 is independent of the air flow entering the second air duct 25 of the air bellow 2 through the second inlet 22, avoiding interference between the air flow in the first air duct 24 and the air flow in the second air duct 25, and improving the air supply effect of the first fan 31 and the second fan 32.

[0036] In some embodiments, the first air duct 24 comprises a first gradually changing section 241 and a first constant section 242 which are sequentially communicated in the length direction of the shell 1, the cross-sectional area of the first gradually changing section 241 gradually increases in the direction towards the first constant section 242, the cross-sectional area of the first constant section 242 is constant in the direction away from the first gradually changing section 241, one end of the first gradually changing section 241 away from the first constant section 242 is the first inlet 21, and the first fan 31 is arranged in the first gradually changing section 241.

[0037] Specifically, as shown in Figures 2-3 the left end of the first gradually changing section 241 is the first inlet 21, the right end of the first gradually changing section 241 is connected with the left end of the first constant section 242, the cross-sectional area of the first gradually changing section 241 gradually increases from left to right, and the cross-sectional area of the first constant section 242 is a fixed value. By arranging the first gradually changing section 241, the flow speed of the air flow entering the first air duct 24 through the first inlet 21 can be gradually reduced, so that the air flow flows smoothly to the first constant section 242. Since the cross-sectional area of the first constant section 242 is a fixed value, the air flow is prevented from being turbulent, a stable air flow in the first air duct 24 is ensured, and the efficiency of the air bellow 2 is improved.

[0038] In some embodiments, the first gradually changing section 241 is conical, and the included angle between the side edge of the cone and the bottom edge of the cone is A1, and A1 is 40°-50°. If A1 is too small, the cross-sectional area of the first gradually changing section 241 changes too much, which is easy to produce noise. Since the air flow rotates when passing through the first fan 31, when A1 is too large, the air flow still has a large rotational speed when blowing from the first gradually changing section 241 to the first constant section 242, which affects the stability of the air flow in the air bellow 2 and the boosting effect is not obvious. By limiting A1, the stability of the air flow is improved while the air flow noise is prevented from being too large.

[0039] For example, A1 is 40°, 45°, 48°, or 50°. In this embodiment, A1 is 45°.

[0040] In some embodiments, the cross section of one end of the first gradually changing section 241 adjacent to the first constant section 242 is a square.

[0041] Specifically, as shown in Figures 1-3 the cross section of the right end of the first gradually changing section 241 is a square. The square is arranged to match the shell 1, which facilitates the installation of the air bellow 2.

[0042] The size of the first constant section 242 in the front-rear direction and the size of the first constant section 242 in the up-down direction are the same, wherein Figure 3 a cross section of the air conditioner perpendicular to the front-rear direction is shown, Figure 4 a cross section of the air conditioner perpendicular to the up-down direction is shown.

[0043] In some embodiments, the first constant section 242 has a length L1 in the length direction of the shell, the first gradually changing section 241 has a length L2 in the length direction of the shell, and L2 / L1 is 0.2-0.3.

[0044] Specifically, as shown in Figure 3 the first constant section 242 has a length L1 in the left-right direction, the first gradually changing section 241 has a length L2 in the left-right direction, and when L2 / L1 is small, the length L1 of the first constant section 242 in the left-right direction is long, and the static pressure of the airflow in the first constant section 242 is low. Since the airflow needs to be pressed out of the air outlet 13 in the high static pressure state in the first constant section 242, the short air supply distance of the air conditioner 100 will be caused by the low static pressure. When L2 / L1 is large, the length L1 of the first constant section 242 in the left-right direction is short, the airflow stabilizing distance is not enough, and the air outlet uniformity is poor. By limiting the value of L2 / L1, the air supply distance of the air conditioner 100 is increased while ensuring that the air conditioner 100 provides stable and uniform airflow.

[0045] For example, L2 / L1 is 0.2, 0.25, or 0.3. In this embodiment, L2 / L1 is 0.25.

[0046] In some embodiments, the second air duct 25 includes a second gradually changing section 251 and a second constant section 252 that are sequentially communicated in the length direction of the shell 1, the cross-sectional area of the second gradually changing section 251 gradually increases in the direction towards the second constant section 252, the cross-sectional area of the second constant section 252 is constant in the direction away from the second gradually changing section 251, one end of the second gradually changing section 251 away from the second constant section 252 is the second inlet 22, and the second fan 32 is arranged in the second gradually changing section 251.

[0047] Specifically, as shown in Figures 2-3 the right end of the second gradually changing section 251 is the second inlet 22, the left end of the second gradually changing section 251 is connected to the right end of the second constant section 252, the cross-sectional area of the second gradually changing section 251 gradually increases from right to left, and the cross-sectional area of the second constant section 252 is a fixed value. By arranging the second gradually changing section 251, the airflow flowing speed entering the second air duct 25 through the second inlet 22 can be gradually reduced, so that the airflow flows smoothly to the second constant section 252. Since the cross-sectional area of the second constant section 252 is a fixed value, the airflow is prevented from being disturbed, stable airflow is formed in the second air duct 25, and the air supply uniformity of the bellow 2 is improved.

[0048] In some embodiments, the second transition section 251 is conical, and the angle between the side and the base of the cone is A1', where A1' is 40°-50°. When A1' is too small, the cross-sectional area of ​​the second transition section 251 changes too much, which can easily generate noise. Since the airflow rotates when passing through the second fan 32, when A1' is too large, the airflow still has a large rotational speed when blowing from the second transition section 251 to the second constant section 252, affecting the airflow stability inside the bellows 2 and resulting in an insignificant pressurization effect. By limiting A1', excessive airflow noise is avoided while improving airflow stability.

[0049] Optionally, A1' and A1 can be set to be the same.

[0050] For example, A1' can be 40°, 45°, 48°, or -50°. In this embodiment, it is 45°.

[0051] In some embodiments, the cross-section of the second gradient segment 251 adjacent to one end of the second constant segment 252 is square.

[0052] Specifically, such as Figures 1-3 As shown, the cross-section of the left end of the second gradient section 251 is square. The square shape can match the housing 1, which facilitates the installation of the bellows 2.

[0053] The second constant segment 252 has the same dimension in the front-to-back direction and the same dimension in the vertical direction. Figure 3 The cross-section of the air conditioner orthogonal to the front-to-back direction is shown. Figure 4 The cross-section of the air conditioner is shown in the vertical direction.

[0054] In some embodiments, the second constant segment 252 has a dimension of L1' in the length direction of the housing 1, the second gradient segment 251 has a dimension of L2' in the length direction of the housing 1, and L2' / L1' takes a value of 0.2-0.3.

[0055] Specifically, such as Figure 3 As shown, the dimension of the second constant segment 252 in the left-right direction is L1', and the dimension of the second gradual segment 251 in the left-right direction is L2'. When the L2' / L1' ratio is small, the dimension of the second constant segment 252 in the left-right direction is long, and the static pressure of the airflow within the second constant segment 252 is low. Since the airflow needs to be forced out of the air outlet 13 under high static pressure within the second constant segment 252, the low static pressure will cause the air supply distance of the air conditioner 100 to be shorter. When the L2' / L1' ratio is large, the dimension of the second constant segment 252 in the left-right direction is short, the air pressure stabilization distance is insufficient, and the uniformity of airflow is poor. By limiting the value of L2' / L1', the air supply distance of the air conditioner 100 is increased while ensuring that the air conditioner 100 provides a stable and uniform airflow.

[0056] Optionally, the size of the first constant section 242 in the left-right direction is the same as the size of the second constant section 252 in the left-right direction, and the size of the first gradual section 241 in the left-right direction is the same as the size of the second gradual section 251 in the left-right direction.

[0057] For example, L2’ / L1’ is 0.2, 0.25, 0.3. In this embodiment, L2’ / L1’ is 0.25.

[0058] In some embodiments, as shown in Figure 2 The cross section of the first inlet 21 and the second inlet 22 is circular. The left end of the first gradual section 241 is the first inlet 21, and the cross section of the first inlet 21 is circular, that is, the cross section of the left end of the first gradual section 241 is circular. The right end of the second gradual section 251 is the second inlet 22, and the cross section of the second inlet 22 is circular, that is, the cross section of the right end of the second gradual section 251 is circular. The circular arrangement makes the airflow smoother during flow, which is beneficial to guiding the uniform distribution of the airflow, thereby improving the stability of the airflow.

[0059] In some embodiments, as shown in Figure 3 In the projection plane perpendicular to the front-rear direction, the diameter of the first inlet 21 and the diameter of the second inlet 22 are L3, the size of the internal space of the bellow 2 in the height direction of the shell 1 is L4, and L3 / L4 is 0.8-0.9.

[0060] When the ratio of L3 / L4 is small, the cross-sectional area of the airflow flow path changes greatly, which is easy to produce noise; when the ratio of L3 / L4 is large, the airflow still has a large rotational speed when it blows from the first gradual section 241 to the first constant section 242 or when it blows from the second gradual section 251 to the second constant section 252, which affects the stability of the airflow in the bellow 2 and the boosting effect is not obvious; by limiting L3 / L4, the stability of the airflow is improved while avoiding excessive airflow noise.

[0061] For example, L3 / L4 is 0.8, 0.85, 0.9. In this embodiment, L3 / L4 is 0.85.

[0062] In some embodiments, the shell 1 has a front panel 14, the air outlet 13 is arranged at at least one of the upper end and the lower end of the front panel 14, and the outlet 23 is arranged at at least one of the upper end and the lower end of the front side of the bellow 2, and the outlet 23 and the air outlet 13 correspondingly communicate.

[0063] Specifically, as shown in Figure 1 and Figure 2As shown, the outlet 23 is arranged opposite to the air outlet 13. When the air outlet 13 is arranged at the upper end of the front panel 14, the outlet 23 is arranged at the upper end of the front side of the air box 2. When the air outlet 13 is arranged at the lower end of the front panel 14, the outlet 23 is arranged at the lower end of the front side of the air box 2. When the air outlet 13 is arranged at the upper end and the lower end of the front panel 14, the outlet 23 is arranged at the upper end and the lower end of the front side of the air box 2. Through the communication between the outlet 23 and the air outlet 13, the airflow in the air box 2 is facilitated to be blown out through the outlet 23 and the air outlet 13.

[0064] Optionally, the shell 1 has a back panel 15, a top panel 16 and a bottom panel 17, the back panel 15 is arranged opposite to the front panel 14 in the front-rear direction, and the top panel 16 and the bottom panel 17 are arranged opposite in the up-down direction.

[0065] In some embodiments, as shown in Figure 1 and Figure 2 As shown, the air conditioner 100 further comprises a deflector 5, which is arranged at the air outlet 13 and rotatably connected with the shell 1. The deflector 5 is arranged corresponding to the air outlet 13. When the air outlet 13 is arranged at the upper end and the lower end of the front panel 14, the deflector 5 is two, one of which is arranged at the upper end air outlet 13, and the other is arranged at the lower end air outlet 13. Through the arrangement of the deflector 5, the airflow blown out of the air outlet 13 is guided, and air supply at different angles is realized.

[0066] Optionally, the deflector 5 at the upper end and the deflector 5 at the lower end can be opened or closed separately. In other words, when the deflector 5 at the upper end and the deflector 5 at the lower end are both closed, the air conditioner 100 is in a closed state. When the deflector 5 at the upper end is opened and the deflector 5 at the lower end is closed, the upper air outlet of the air conditioner 100 is realized. When the deflector 5 at the upper end is opened and the deflector 5 at the lower end is opened, the upper air outlet and the lower air outlet of the air conditioner 100 are realized. When the deflector 5 at the upper end is closed and the deflector 5 at the lower end is opened, the lower air outlet of the air conditioner 100 is realized. Through the control of the state of the upper end deflector 5 and the lower end deflector 5, different air supply modes of the air conditioner 100 are realized, and the user experience is improved.

[0067] In the cooling mode, by opening the upper end deflector 5, the air outlet height of the air outlet 13 is higher, avoiding the direct blowing of the airflow to the human body, realizing the sky curtain air supply, and improving the user experience in the heating mode. In the heating mode, by opening the lower end deflector 5 and rotating the lower end deflector 5 to guide the airflow to flow downward, the carpet air supply is realized, and the comfort of the user in the heating mode is improved.

[0068] In some embodiments, as shown in Figure 2As shown, the first fan 31 and the second fan 32 are axial flow fans. The air conditioner 100 also includes a first bracket 61 and a second bracket 62. The first bracket 61 is located inside the air box 2 and adjacent to the first inlet 21. The first fan 31 is located on the first bracket 61. The second bracket 62 is located inside the air box 2 and adjacent to the second inlet 22. The second fan 32 is located on the second bracket 62.

[0069] The first bracket 61 installs the first fan 31 inside the first transition section 241. Since the first fan 31 is an axial flow fan and the cross-section of the first inlet 21 is circular, the first fan 31 is arranged coaxially with the circle, which facilitates the circumferential rotation of the axial flow fan to intake air and improves the air intake efficiency of the first fan 31.

[0070] The second bracket 62 installs the second fan 32 inside the second transition section 251. Since the second fan 32 is an axial flow fan and the cross-section of the second inlet 22 is circular, the second fan 32 is arranged coaxially with the circle, which facilitates the circumferential rotation of the axial flow fan to intake air and improves the air intake efficiency of the second fan 32.

[0071] By setting both the first fan 31 and the second fan 32 as axial flow fans, the external airflow only needs a 90-degree bend from entering the casing 1 to being blown out, thereby improving the airflow efficiency.

[0072] In some embodiments, the air inlet 12 includes a first air inlet 121 and a second air inlet 122. The first air inlet 121 is located at one end of the housing 1 along its length, and the second air inlet 122 is located at the other end of the housing 1 along its length. The air conditioner 100 also includes a first evaporator 71 and a second evaporator 72. The first evaporator 71 and the second evaporator 72 are located in the chamber 11. The first evaporator 71 is located between the first air inlet 121 and the first inlet 21, and the second evaporator 72 is located between the second air inlet 122 and the second inlet 22.

[0073] Specifically, such as Figures 1-4 As shown, the first air inlet 121 is located at the left end of the housing 1. By placing the first evaporator 71 between the first air inlet 121 and the first inlet 21, the external airflow enters the chamber 11 through the first air inlet 121 and exchanges heat with the first evaporator 71. The airflow after heat exchange enters the first air duct 24 through the first inlet 21, so that the first air duct 24 is in a high static pressure state. When the air guide plate 5 is opened, it is blown out through the outlet 23 and the air outlet 13 of the first air duct 24.

[0074] The second air inlet 122 is located at the right end of the housing 1. By placing the second evaporator 72 between the second air inlet 122 and the second inlet 22, the external airflow enters the chamber 11 through the second air inlet 122 and exchanges heat with the second evaporator 72. The airflow after heat exchange enters the second air duct 25 through the second inlet 22, so that the second air duct 25 is in a high static pressure state. When the air guide plate 5 is opened, it is blown out through the outlet 23 and the air outlet 13 of the second air duct 25.

[0075] Compared to the air intake method of the related technology that uses top air intake and bottom air outlet, which requires a gap to be reserved between the upper end of the air conditioner 100 and the ceiling, this embodiment sets air inlets 12 at the left and right ends of the housing 1 and air outlets 13 at the upper and lower ends of the front panel 14, so that the external airflow enters the air box 2 from the left and right ends of the housing 1 and is blown out from the front air outlet 13, which facilitates the ceiling installation of the air conditioner 100.

[0076] In other embodiments, the first evaporator 71 is disposed within the air box 2 and downstream of the first fan 31. For example, the first evaporator 71 is disposed within the first transition section 241 and to the right of the first fan 31. Alternatively, the first evaporator 71 may also be disposed adjacent to the air outlet 13 and upstream of the air outlet 13.

[0077] In some embodiments, the air inlet 12 extends through the housing 1 along the length direction of the housing 1, the chamber 11 forms a first air inlet 121 at one end of the housing 1 along the length direction of the housing 1, and forms a second air inlet 122 at the other end of the chamber 11 along the length direction of the housing 1. The air conditioner 100 also includes a first air inlet grille 81 and a second air inlet grille 82, the first air inlet grille 81 is disposed at the first air inlet 121, and the second air inlet grille 82 is disposed at the second air inlet 122.

[0078] Specifically, such as Figures 2-4 As shown, the air inlet 12 penetrates the housing 1 in a left-right direction. A first air inlet 121 is formed at the left end of the chamber 11, and a second air inlet 122 is formed at the right end of the chamber 11. This allows external airflow to enter the chamber 11 simultaneously from both the first and second air inlets 121, increasing the air intake volume. By providing a first air intake grille 81 at the first air inlet 121 and a second air intake grille 82 at the second air inlet 122, airflow into the chamber 11 is facilitated while preventing foreign objects from entering, thus improving the safety of the air conditioner 100.
