Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and specifically, to a fan assembly and an air outlet device. Background Art

[0002] Existing air conditioner cabinet units mostly use centrifugal fans or cross-flow fans for air supply. Since it is difficult to adjust the air supply direction of centrifugal fans and cross-flow fans in a timely manner, it is not possible to well achieve the diversification of the air supply modes of air conditioner cabinet units, and it is difficult to make the air conditioner cabinet units have good use comfort in both the cooling and heating modes.

[0003] Since the air duct profile of general air conditioners is fixed, multi-air outlet air conditioners need to take into account the air supply volume of each air outlet, resulting in a non-optimal profile when there is a single air outlet, and the air volume does not reach the maximum. For example, for an up-and-down air outlet air conditioner, the air duct profile needs to take into account the air supply volume of single up air outlet and single down air outlet, resulting in a loss of part of the air volume when there is a single up air outlet, which is lower than the air volume of an air conditioner designed for single up air outlet.

[0004] At the same time, existing axial fans generally can only supply air in one direction. For a vertical air conditioner with two-way air inlet and outlet, in the up air outlet mode and the down air outlet mode, due to the different air flow directions, only one of the fans supplies air in each mode, resulting in a small air volume. If the number of fans is increased, the cost will increase and a large space inside the air conditioner will be occupied. Summary of the Utility Model

[0005] The first object of the present utility model is to provide a fan assembly that can achieve two-way air supply and increase the air volume.

[0006] The second object of the present invention is to provide an air outlet device using the above fan assembly.

[0007] To achieve the above first object, the present utility model provides a fan assembly, which is applied to an air outlet device. The air outlet device further includes a housing, on which a first air outlet and a second air outlet are opened. The fan assembly is located between the first air outlet and the second air outlet. The fan assembly includes a fan blade and a fan blade driving member, and the fan blade driving member drives the fan blade to rotate. The fan assembly further includes a fan blade support and a support driving member. The fan blade support is rotatably connected to the housing, the support driving member is fixed on the housing, the fan blade driving member is arranged on the fan blade support, and the rotation axis of the fan blade support is perpendicular to the rotation axis of the fan blade. When the air outlet device is in the first air outlet state where the second air outlet is for air inlet and the first air outlet is for air outlet, the fan assembly supplies air towards the first air outlet. When the air outlet device is switched from the first air outlet state to the second air outlet state where the first air outlet is for air inlet and the second air outlet is for air outlet, the support driving member drives the fan blade support to flip, the fan blade support drives the fan blade to flip, and the fan assembly supplies air towards the second air outlet.

[0008] As can be seen from the above solution, when the air outlet direction needs to be reversed, the support driving member drives the air blade support to flip, so as to change the air supply direction of the fan assembly. The air blade driving member drives the air blade to rotate, realizing the conversion of the air outlet direction, thus overcoming the problem that the existing fan can only supply air unidirectionally and the air supply efficiency is low. This fan assembly can realize bidirectional air supply, increase the air volume, and at the same time solve the problem that the air supply mode of the existing up-and-down air outlet air conditioner is fixed, resulting in the failure to achieve the best energy saving and comfort experience under different working conditions.

[0009] A preferred solution is that the air blade support includes a support main body and a support rotating shaft; the support main body is in a cylindrical shape with openings at both ends. There is a support air duct inside the support main body. The support air duct penetrates the support main body along the axial direction of the support main body. The air blade is located inside the support air duct. The axial direction of the support main body is parallel to the rotating shaft of the air blade; the support rotating shaft includes a first rotating shaft section and a second rotating shaft section arranged coaxially. Both the first rotating shaft section and the second rotating shaft section protrude outward from the support main body. Both the first rotating shaft section and the second rotating shaft section are rotationally matched with the housing; the support driving member is connected to the first rotating shaft section.

[0010] Thus, it can be seen that the cylindrical support main body can achieve good guidance of the air flow. The first rotating shaft section and the second rotating shaft section are used to support the air blade support, ensuring the stable connection of the air blade support with components such as the air conditioner housing.

[0011] A further solution is that the air blade support further includes a driving member mounting seat and more than two connecting ribs. The air blade driving member is located inside the driving member mounting seat; both the driving member mounting seat and the connecting ribs are located at the first end of the support main body. Both ends of each connecting rib are respectively connected to the outer peripheral wall of the driving member mounting seat and the inner peripheral wall of the support main body. The connecting ribs are arranged at intervals along the circumferential direction of the driving member mounting seat.

[0012] Thus, it can be seen that the driving member mounting seat is fixed relative to the support main body through more than two connecting ribs. On the one hand, it can ensure the stability of the connection between the two. On the other hand, the connecting ribs of the fixing frame have a small area and will not block the air flow, ensuring the air volume.

[0013] A further solution is that an installation opening is provided at the end of the driving member mounting seat away from the air blade. A diversion cover is arranged at the installation opening. The outer surface of the diversion cover is a convex arc surface protruding in the direction away from the air blade.

[0014] Thus, it can be seen that the diversion cover can guide the air flow and avoid the air flow directly hitting the motor plane, resulting in air volume loss.

[0015] A preferred solution is that the air blade is an axial flow air blade.

[0016] Thus, it can be seen that the air supply direction of the axial flow fan assembly is easier to control and the air supply volume is also larger.

[0017] To achieve the above second objective, the present utility model provides an air outlet device, which includes a housing and the above-mentioned fan assembly. The housing is provided with a first air outlet and a second air outlet, and the fan assembly is located between the first air outlet and the second air outlet.

[0018] As can be seen from the above solution, when the air outlet device needs to blow air from the first air outlet, the blade driving member drives the blades to rotate, guiding the air flow from the second air outlet to the first air outlet; when the air outlet device needs to blow air from the second air outlet, the support driving member drives the blade support to flip, so as to change the air supply direction of the fan assembly, and the blade driving member drives the blades to rotate, guiding the air flow from the first air outlet to the second air outlet, thereby overcoming the problem that the existing fan can only supply air unidirectionally and the air supply efficiency is low. This air outlet device can realize bidirectional air supply, increase the air volume, and at the same time solve the problem that the air supply mode of the up-and-down air conditioner is fixed, resulting in the failure to achieve the best energy saving and comfort experience under different working conditions.

[0019] A preferred solution is that the air outlet device further includes a heat exchanger assembly, and the heat exchanger assembly is located between the two fan assemblies; the heat exchanger assembly includes a first heat exchanger and a second heat exchanger. In the air supply direction, the first end of the first heat exchanger is arranged close to the first end of the second heat exchanger, and the second end of the first heat exchanger is arranged far from the second end of the second heat exchanger.

[0020] It can be seen that by arranging the first heat exchanger and the second heat exchanger obliquely, the area of the heat exchanger assembly is large and the heat exchange efficiency is high.

[0021] A further solution is that the air supply direction is parallel to the vertical direction. The first end of the first heat exchanger and the first end of the second heat exchanger are both located at the bottom end of the heat exchanger assembly, and the second end of the first heat exchanger and the second end of the second heat exchanger are both located at the top end of the heat exchanger assembly.

[0022] A preferred solution is that the number of fan assemblies is more than two, and two of the fan assemblies are respectively arranged close to the first air outlet and the second air outlet; the air outlet device further includes two filter screen assemblies. The first filter screen assembly is located between the first fan assembly and the first air outlet, and the second filter screen assembly is located between the second fan assembly and the second air outlet.

[0023] It can be seen that by arranging fan assemblies at the first air outlet and the second air outlet respectively, the air intake and air output of the two air outlets are increased, and the air supply efficiency is improved.

[0024] A further solution is that the filter screen assembly includes an outer filter screen fixing frame, an inner filter screen fixing frame, a filter screen, a rotating cover, and a filter screen driving member; the outer filter screen fixing frame is installed on the housing, the inner filter screen fixing frame is located inside the outer filter screen fixing frame and fixedly connected to the outer filter screen fixing frame, and a filtering channel is formed between the outer filter screen fixing frame and the inner filter screen fixing frame; the filter screen driving member is installed on the inner filter screen fixing frame, and the rotating cover is rotatably connected to the inner filter screen fixing frame; the filter screen is annular, the rotating cover is located radially inside the filter screen, the filter screen is provided with fixing rods and active sliding rods, the fixing rods and the active sliding rods are respectively arranged on both sides of the circumference of the filter screen, and both the fixing rods and the active sliding rods extend along the radial direction of the filter screen; both ends of the fixing rods are respectively fixedly connected to the outer peripheral wall of the inner filter screen fixing frame and the inner peripheral wall of the outer filter screen fixing frame; a first sliding groove extending along the circumference of the outer filter screen fixing frame is provided on the inner peripheral wall of the outer filter screen fixing frame, the first end of the active sliding rod is fixedly connected to the rotating cover, and the second end of the active sliding rod is slidably matched with the first sliding groove; the filter screen driving member drives the rotating cover to rotate, and the rotating cover drives the active sliding rod to rotate towards the fixing rod to fold the filter screen, or drives the active sliding rod to move away from the fixing rod to unfold the filter screen.

[0025] It can be seen that when the air inlet near the filter screen assembly is in the air inlet mode, the filter screen driving member drives the rotating cover to rotate, and the rotating cover drives the active sliding rod to move away from the fixing rod to unfold the filter screen; when the air inlet near the filter screen assembly is in the air outlet mode, the filter screen driving member drives the rotating cover to rotate in the reverse direction, and the rotating cover drives the active sliding rod to rotate towards the fixing rod to fold the filter screen. Thus, the function of filtering the air flow during air inlet and avoiding the air flow during air outlet is achieved.

[0026] A further solution is that a second sliding groove extending along the circumference of the inner filter screen fixing frame is provided on the inner filter screen fixing frame; a passive sliding rod is further provided on the filter screen, and in the circumferential direction of the filter screen assembly, the passive sliding rod is located between the fixing rod and the active sliding rod; the passive sliding rod extends along the radial direction of the filter screen, and both ends of the passive sliding rod are respectively slidably matched with the first sliding groove and the second sliding groove.

[0027] It can be seen that by providing the passive sliding rod, on the one hand, the support of the filter screen in the unfolded state can be realized, avoiding damage to the filter screen caused by excessive air flow, and on the other hand, it is also convenient to fold the filter screen.

[0028] A preferred solution is that the filter screen assembly includes a filter screen fixing frame, a filter screen, and a filter screen driving assembly; the filter screen fixing frame includes a filter screen support, a driving part support, and a fixing frame connecting rib; the filter screen support is annular, the middle part of the filter screen support is a filtering channel, the driving part support is located in the middle of the filter screen support and is arranged coaxially with the filter screen support; the fixing frame connecting rib extends along the radial direction of the filter screen assembly, and both ends of the fixing frame connecting rib are respectively connected to the filter screen support and the driving part support, and a rib slide rail extending along the length direction of the fixing frame connecting rib is provided on the fixing frame connecting rib; the filter screen includes a filter screen main body, a support member, and a connecting member that are fixedly connected, the filter screen main body can cover the filtering channel, the connecting member is arranged in the middle of the filter screen main body, the first end of the support member is connected to the connecting member, and the second end of the support member is slidably connected to the rib slide rail; the filter screen driving assembly includes a filter screen driving member and a screw rod, the screw rod extends along the normal direction of the filter screen main body, the connecting member is threadedly connected to the screw rod, the filter screen driving member drives the screw rod to rotate, the screw rod drives the connecting member to move along the extending direction of the screw rod, and the connecting member drives the filter screen main body to fold or unfold.

[0029] It can be seen that when the air outlet near the filter screen assembly is in the air inlet mode, the filter screen driving member drives the screw rod to rotate, the screw rod drives the connecting member to move along the extending direction of the screw rod, and the connecting member drives the filter screen main body to unfold; when the air outlet near the filter screen assembly is in the air outlet mode, the filter screen driving member drives the screw rod to rotate in the reverse direction, the screw rod drives the connecting member to move along the extending direction of the screw rod, and the connecting member drives the filter screen main body to fold. Thus, the function of filtering the air flow during air inlet and avoiding the air flow during air outlet is realized.

[0030] A further solution is that the number of support members is two or more, and multiple support members are arranged at intervals along the circumferential direction of the filter screen support. The number of fixing frame connecting ribs is two or more, and the fixing frame connecting ribs are arranged in one-to-one correspondence with the support members.

[0031] It can be seen that by arranging multiple support members, on the one hand, the support of the filter screen in the unfolded state can be realized, avoiding damage to the filter screen caused by too large air flow. On the other hand, it is also convenient to fold the filter screen, facilitating the folding of the filter screen to the screw rod and avoiding the air flow to the greatest extent.

[0059] See [[ID=I3]] Figures 2 to 5 , the structures of the upper fan assembly 5 and the lower fan assembly 6 are the same, and both include a fan blade 51, a fan blade driving member 52, a fan blade support 53, and a support driving member (not shown). The fan blade 51 is an axial flow fan blade. The fan blade driving member 52 drives the fan blade 51 to rotate. The fan blade driving member 52 is arranged on the fan blade support 53.

The diversion cover 539 is located outside the fixing cover 538. The outer surface 5391 of the diversion cover 539 is a convex arc surface protruding in a direction away from the wind blade 51.

[0063] See Figure 2 and Figures 6 to 9 As shown in, the structures of the upper filter assembly 2 and the lower filter assembly 3 are the same, and both include a filter outer fixing frame 31, a filter inner fixing frame 32, a filter screen 33, a rotating cover 35, and a filter screen driving part 34.

Both ends of the driven slide rod 333 are slidably engaged with the first chute 311 and the second chute 321 respectively.

[0067] See Figure 10 , when the air conditioner is in the cooling mode or the dehumidifying mode, that is, when the air conditioner is in the first air outlet state where the lower air outlet 12 intakes air and the upper air outlet 11 discharges air, the filter screen driving member 34 of the lower filter screen assembly 3 drives the filter screen 33 to unfold, and at the same time, the filter screen driving member 34 of the upper filter screen assembly 2 drives the filter screen 33 to fold. The impeller driving member drives the impeller to rotate, guiding the air flow from the lower air outlet 12 to the upper air outlet 11.

[0068] See Figure 11When the air conditioner switches from the cooling mode or the dehumidifying mode to the heating mode, that is, when the air conditioner switches from the first air outlet state to the second air outlet state where the upper air inlet 11 intakes air and the lower air outlet 12 discharges air, the filter screen driving member 34 of the upper filter screen assembly 2 drives the filter screen 33 to unfold, and at the same time, the filter screen driving member 34 of the lower filter screen assembly 3 drives the filter screen 33 to fold. The support driving member drives the air blade support 53 to flip 180 degrees to change the air supply direction of the fan assembly, and the air blade driving member drives the air blade to rotate to guide the air flow from the upper air inlet 11 to the lower air outlet 12. When the air conditioner switches from the heating mode to the cooling mode, the support driving members of the upper fan assembly 5 and the lower fan assembly 6 both drive the corresponding air blade supports 53 to flip 180 degrees.

[0069] As can be seen from the above, this air conditioner can overcome the problem that the existing fan can only supply air unidirectionally with low air supply efficiency. This air outlet device can realize bidirectional air supply, increase the air volume, and at the same time solve the problem that the air supply method of the upper and lower air outlet air conditioners is fixed, resulting in the failure to achieve the best energy saving and comfort experience under different working conditions. The filter screen assembly has a simple structure and can realize filtration during air intake and avoidance during air discharge.
