Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically to an air guide mechanism and an air conditioner including the air guide mechanism. Background Technology

[0002] The fresh air module is part of the air conditioning circulation system, mainly used to achieve the circulation, exchange, and even purification of indoor and outdoor air. Generally, the air outlet of the fresh air module is set independently of the air conditioner's hot and cold air outlets. To prevent the airflow from the fresh air module's outlet from blowing directly on people, some products add an air outlet panel to the casing. The air outlet panel has formed air outlet holes that connect with the fresh air module's air outlet pipes, etc. A grille is fixed at the opening of the air outlet. This solution has a small airflow direction adjustment effect, or the grille can be flipped up and down by a drive component, but the airflow direction adjustment range is limited and needs improvement. Summary of the Invention

[0003] To address at least one of the aforementioned technical deficiencies, the present invention provides the following technical solution:

[0004] The first aspect of this application discloses an air guiding mechanism, including an air outlet panel and an air guiding assembly. The air guiding assembly is disposed at the air outlet of the air outlet panel. The air guiding assembly includes a swing arm assembly, a driving member for driving the swing arm assembly to rotate, and a panel. The panel is disposed on the swing arm assembly to rotate synchronously relative to the air outlet. Under the support of the swing arm assembly, a portion of the panel is higher than the top opening of the air outlet, and a radially open air outlet channel is formed between this portion of the panel and the wall of the air outlet. Driven by the driving member, the portion of the panel higher than the top opening of the air outlet moves circumferentially along the air outlet, thereby forming air outlet channels with openings facing different directions with the corresponding hole walls.

[0005] In this design, the panel is supported by a swing arm assembly, making it higher than the top opening of the air outlet. This panel and the hole wall form a radially open air outlet channel, which is the outlet of the air outlet channel. The airflow entering from the bottom opening of the air outlet is blocked by the panel and flows out through the radial outlet. Driven by the rotation of the drive component, the outlet continuously forms in different directions around the air outlet, providing a wide range of airflow adjustment. This effectively avoids the airflow blowing directly on the human body, improving comfort. This air guide mechanism can be applied to the required air outlet appliances, such as air conditioners, as needed.

[0006] For the panel, it can be partially or completely exposed outside the air outlet. The driving components include drive motors, or drive motors paired with corresponding transmission mechanisms, such as transmission gear sets.

[0007] For the drive unit, it can be either directly fixed to the air outlet panel or installed on the corresponding air outlet electrical unit.

[0008] Furthermore, the swing arm assembly includes a base and a swing arm. The panel and the base are connected by an insertion joint. The swing arm is provided on the peripheral wall of the base. The axial extension of the swing arm abuts against the bottom surface of the panel to form a support. The supported plate portion is higher than the air outlet opening.

[0009] This design adds a base to facilitate docking with panels, drive components, etc., and to facilitate docking and installation with the air outlet panel. The base and panel are molded independently. The panel and base are easily connected and installed by plugging in. The base can be rotated to a predetermined angle under the support of the swing rod so that the supported plate is higher than the air outlet opening, making assembly convenient.

[0010] Furthermore, a shaft is provided at the center of the bottom surface of the panel, and the bottom end of the shaft is rotatably connected to the top end of the base by a ball. This design adds the shaft to facilitate docking with the base, such as by forming a circular groove on the top surface of the base for the ball to insert into.

[0011] Furthermore, the panel is flat and tilted at the air outlet under the support of the axial extension of the swing arm. The higher part of the panel is above the top opening of the air outlet, while the lower part is inside the air outlet cavity with its side abutting or clearance fit against the hole wall. In this design, part of the panel is outside the air outlet, and part is inside the air outlet with abutting or clearance fit against the hole wall to better allow airflow to exit from the radial outlet.

[0012] Furthermore, the swing arm includes a radial extension portion, which is connected to the base body and has an axial extension portion to facilitate support of the panel. The swing arm can be integrally formed with the base body. The radial extension portion is not limited to the radial direction of the air outlet, but also includes directions that are at an angle to the radial direction of the air outlet, etc., which can be selected as needed.

[0013] Furthermore, a carrier plate is provided inside the air outlet, the driving component is mounted on the carrier plate, the output end of the driving component is connected to the base body, and the driving component is fixed to the air outlet panel, which facilitates modularization and installation of corresponding electrical appliances.

[0014] Furthermore, the rotation center line of the panel is parallel to the axial line of the air outlet, so that during rotation, the panel body exposed outside the air outlet can better form air outlet channels with different outlet orientations with the hole wall.

[0015] The second aspect of this application discloses an air conditioner, which includes the air guiding mechanism described in any of the above claims, such as an air outlet of a fresh air module, to effectively prevent direct airflow.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. The present invention designs a novel air guiding mechanism, which drives the panel to rotate through a driving component. The panel body exposed outside the air outlet and the hole wall form a radially open air outlet channel. During the rotation, the opening faces different directions to avoid direct airflow and improve comfort. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] like Figure 1 , Figure 2 , Figure 3 As shown, in this example, the air guiding mechanism includes an air outlet panel 1 and an air guiding assembly. An air outlet 5 is formed on the left side of the air outlet panel 1, and the air guiding assembly is installed at the air outlet 5. The air guiding assembly includes a rocker arm assembly, a drive component 3 for driving the rocker arm assembly to rotate, and a panel 2.

[0027] like Figure 1 , Figure 2 As shown, panel 2 is a circular flat plate. Figure 1 , Figure 2In the state shown, panel 2 is placed at an angle. The left end plate of panel 2 (i.e., the plate at the higher position) is higher than the top opening of air outlet 5 and is exposed. An air outlet cavity is formed between the left end plate and the wall of the air outlet to guide the airflow. There is a gap of a predetermined height between the bottom surface of the left end plate and the bottom surface of the air outlet below. That is, the outlet 4 of the air outlet cavity opens radially along the air outlet. The airflow that flows in from the bottom opening of the air outlet is guided upward by the wall of the air outlet and then flows out from the outlet through the panel.

[0028] In this example, the right end of panel 2 (i.e., the lower-positioned panel) is below the top opening of air outlet 5, meaning it is inside the air outlet cavity. The side of the right end of panel 2 abuts against or maintains a predetermined gap with the wall of air outlet 5. In this state, airflow is better guided out of the outlet. In this state, the diameter of the panel is slightly smaller than the diameter of the air outlet. Of course, the entire panel can also be tilted and exposed outside the air outlet opening as needed. In this state, the diameter of the panel can be selected to be larger than the diameter of the air outlet.

[0029] In this example, a rocker arm assembly and a drive unit 3 are installed inside the air outlet 5 cavity below panel 2, and panel 2 is mounted on the rocker arm assembly. Specifically, the rocker arm assembly includes a rocker arm and a base 7. A strip-shaped carrier plate 6 is integrally formed radially at the bottom opening of the air outlet 5. The drive unit 3 is a drive motor, which is fixed to the carrier plate 6 by screws or the like. The output end of the drive motor extends from a hole formed in the carrier plate 6 and is fixed to the bottom end of the base 7 above, or a connecting shaft is installed at the output end of the drive motor and connected to the bottom end of the base through the connecting shaft. Alternatively, the output end of the drive motor can be connected to the base through a gear transmission mechanism or the like. Of course, to improve stability, the bottom end of the base 7 can be rotatably connected to the carrier plate 6 through bearings or the like. Preferably, the rotation center line of the panel is parallel to the axial line of the air outlet. The axial line of the air outlet is the axial center line of the air outlet or a line parallel to its axial center line. The rotation center line of the panel can coincide with or be parallel to the axial center line of the air outlet. During rotation, the panel exposed outside the air outlet can better form air outlet channels with different outlet orientations with the hole wall.

[0030] In this example, panel 2 and base 7 are connected by a plug-in structure, specifically by a spherical rotation connection. A shaft 8 is formed along the axial direction at the middle of the bottom surface of panel 2, and a sphere 9 is formed at the bottom end of shaft 8. A matching spherical slot is formed on the top surface of base 7. During installation, the sphere at the end of shaft is inserted into the slot, so that base and panel form a spherical rotation connection. During the plug-in connection of panel and base, the spherical rotation connection method allows panel to be tilted directly under the support of the swing rod.

[0031] As for the rocker arm, the rocker arm is installed on the periphery of the base 7, and the axial extension 82 of the rocker arm abuts against the bottom surface of the left end plate of the panel 2 to form support. The top end of the axial extension 82 of the rocker arm extends to the top opening of the air outlet 5. During the panel insertion process, the bottom surface of the left end plate of the panel is tilted directly by the axial extension of the rocker arm. The left end plate of the panel 2 is exposed outside the air outlet 5 under the support of the rocker arm. Of course, the axial extension in the axial extension part only refers to the overall upward extension along the axial direction of the air outlet.

[0032] Regarding the connection between the rocker arm and the base, the rocker arm may also include a radial extension 81, an axial extension 82 at the beginning of the radial extension 81, and a tail end of the radial extension 81 at the periphery of the base 7. This can be achieved through fitting, screwing, or the rocker arm can be directly integrally formed with the base. Of course, the radial extension in the radial extension refers only to its overall radial extension along the air outlet.

[0033] Driven by the motor, the swing arm and seat rotate, and the panel rotates synchronously. The left end plate of the panel, which is higher than the top opening of the air outlet, moves along the circumference of the air outlet, thereby forming an air outlet channel with the corresponding hole wall facing different directions. This allows the airflow to flow in different directions, effectively preventing the air from blowing directly on the human body and improving comfort.

[0034] This air guide mechanism can be installed on the required electrical appliances, such as air conditioners. When the air guide mechanism is installed on an air conditioner with a fresh air module, the air outlet panel is directly fixed to the corresponding air conditioner housing. The bottom opening of the air outlet of the air outlet panel is connected to the air outlet duct of the fresh air module, etc., to effectively prevent the airflow from blowing directly.

[0035] For fixing the air outlet panel to the air conditioner housing, such as with a snap-on fastening method, both ends of the air outlet panel are bent downwards. A positioning block 10 is formed near the bend at the first end, extending at an angle towards the bend to pre-position and guide movement. A protrusion, positioning block 3 12, is formed at the end of the bend at the tail end, serving to secure and limit the movement. L-shaped positioning blocks 2 11 are formed at intervals between positioning blocks 10 and 3 12, serving to secure and limit the movement. Of course, reinforcing plates can be formed around positioning blocks 1, 2, and 3 to improve structural strength. Slots that mate with the above-mentioned blocks are formed at corresponding positions on the air conditioner housing for snap-on assembly, improving installation efficiency.

[0036] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
