Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an air guide mechanism and an air outlet device. Background Art

[0002] With the development of air conditioners, most mobile air conditioners are designed with top air outlet. The air outlet components of existing mobile air conditioner products on the market are non-rotatable structures. Instead, air is supplied through an air guide structure. The air guide structure drives the shaft to rotate through a stepper motor, thereby achieving directional air supply within a certain range of angles and the effect of closing or opening the air outlet.

[0003] Because most portable air conditioners feature a single, single-plate air guide, air flowing from the air outlet along the guide tends to flow to the sides of the airflow, reducing the front-end airflow and, consequently, the airflow distance. Furthermore, by swinging the guide within a certain range of angles, the airflow remains constant, resulting in uneven cooling and a poor user experience.

[0004] There is an existing wind guide structure, which includes a wind guide plate and a wind shield, the wind shield is connected to the wind guide plate, and the wind guide plate and the wind shield surround and define an air outlet; wherein the air outlet defines the air supply direction, and the wind shield is arranged on the side relative to the air supply direction. The arrangement of the wind shield can make the side of the air outlet closed, so that when the air flow is supplied, the air flow will not diverge toward the side of the air supply direction, but will concentrate the air flow at the end of the air outlet for supplying air, thereby increasing the air supply airflow at the end of the air outlet and thus increasing the air supply distance. However, this air guide mechanism can only supply air forward and cannot discharge air from the top, and the swing angle is small, the air supply range is small, and the temperature drop is uneven.

[0005] Another type of duct assembly uses a drive assembly to rotate a disc, thereby moving the air outlet. This allows the outlet to rotate along a predetermined circular path, thereby controlling the airflow direction. This allows for more flexible adjustment, meeting the airflow direction requirements of different scenarios and users, improving device functionality and user comfort. However, this duct assembly only changes the horizontal direction of airflow and cannot deliver air upwards, effectively blowing directly onto the body. This results in uneven cooling and a poor user experience. Utility Model Content

[0006] The first purpose of the utility model is to provide an air guide mechanism that can achieve the change of air volume, control the air supply distance, and improve the comfort of users.

[0007] The second object of the present utility model is to provide an air outlet device using the above-mentioned air guide mechanism.

[0008] In order to achieve the above-mentioned first purpose, the utility model provides an air guide mechanism, comprising: a protective cover, the protective cover is columnar, a protective cover air inlet and a protective cover air outlet are opened on the peripheral wall of the protective cover, the protective cover air outlet comprises a first air outlet portion and a second air outlet portion arranged along the circumference of the protective cover; a first air guide assembly, the first air guide assembly comprises a first air guide plate and a first driving member, the first driving member can drive the first air guide plate to swing along the circumference of the protective cover between a first closed position and a first open position, in the first closed position, the first air guide plate covers the first air outlet portion, and in the first open position, the first air guide plate covers the first air outlet portion. position, the first air guide plate opens the first air outlet; the second air guide assembly, the second air guide assembly includes a second air guide plate and a second driving member, the second driving member can drive the second air guide plate to swing along the circumference of the protective cover between the second closed position and the second open position, in the second closed position, the second air guide plate covers the second air outlet, and in the second open position, the second air guide plate opens the second air outlet; the first air guide plate and the second air guide plate both extend along the length direction of the protective cover and are arranged along the circumference of the protective cover, and the air outlet of the air guide mechanism is surrounded by the first air guide plate and the second air guide plate.

[0009] As can be seen from the above solution, by providing the first and second air guide plates, the size and direction of the air outlet can be flexibly adjusted by adjusting the relative position of the first and second air guide plates, thereby achieving changes in air volume, controlling the air supply distance, and improving user comfort. In addition, compared to the single air guide plate of the prior art, by providing a protective cover to block the airflow from both ends of the air guide plate, the airflow will not diverge to the side in the air supply direction, but will be concentrated towards the end of the air outlet of the air guide mechanism for air supply. At the same time, the air outlet of the air guide mechanism formed by the two air guide plates has the effect of gathering wind, which can increase the air supply distance.

[0010] In a preferred embodiment, each of the first and second air deflectors includes a plate body and a connecting portion. The plate body has an arcuate cross-section. The connecting portion is located near an end of the plate body and extends radially outward from an inner peripheral wall of the plate body. A mounting portion is provided at one end of the connecting portion distal from the plate body, and the mounting portion engages with a drive shaft of a corresponding drive member. The connecting portion of the first and second air deflectors is disposed at respective ends of the protective cover in a longitudinal direction.

[0011] As can be seen, the curved plate body enables the air deflector to rotate more smoothly within the protective cover, and the connection portion is provided on the end wall of the plate body to avoid obstruction of airflow. Furthermore, the connection portions of the two air deflectors are respectively provided at the two ends of the protective cover in the longitudinal direction, which can prevent interference between the two connection portions during rotation. Furthermore, the two driving members can be respectively provided at the two ends of the protective cover, facilitating the independent control of the two air deflectors.

[0012] A further solution is that the connecting portion is fan-shaped, and the connecting portion has a first radius edge and a second radius edge; the plate body has a first plate edge and a second plate edge, and the first plate edge and the second plate edge are respectively arranged on both sides of the width direction of the plate body; the first radius edge extends from the mounting portion to the first plate edge, and the second radius edge extends from the mounting portion to the second plate edge.

[0013] It can be seen that the fan-shaped connecting portion can improve the stability of the connection between the connecting portion and the plate body, making it easier for the connecting portion to transmit the driving force to the plate body.

[0014] A preferred solution is that an axial hole is provided on the end wall of the protective cover, and the mounting portion extends outward from the surface of the connecting portion along the length direction of the protective cover, and the drive shaft corresponding to the mounting portion rotates in cooperation with the axial hole, and a mating protrusion is provided on the outer peripheral wall of the drive shaft; a first limiting protrusion and a second limiting protrusion arranged at intervals are provided on the outer surface of the end wall of the protective cover near the axial hole, and the mating protrusion is located between the first limiting protrusion and the second limiting protrusion to limit the rotation angle of the corresponding drive shaft.

[0015] It can be seen that by cooperating with the mating protrusion on the drive shaft and the two limiting protrusions on the protective cover, the rotation angle of the air guide plate can be limited to prevent the air guide plate from rotating excessively and causing obstruction of the air flow or inability to close the air outlet of the air guide mechanism.

[0016] A preferred solution is that the gaps between the plate body of the first air guide plate and the plate body of the second air guide plate and the protective cover are both in the range of 1 mm to 3 mm.

[0017] It can be seen from this that the gap between the main body of the air guide plate and the protective cover should be reasonably designed to ensure the smooth movement of the air guide plate.

[0018] A preferred solution is that the peripheral wall of the protective cover includes a first guide wall and a second guide wall arranged at intervals along the circumference of the protective cover; the top edge of the first guide wall and the top edge of the second guide wall form an air outlet of the protective cover; the bottom edge of the first guide wall and the bottom edge of the second guide wall form an air inlet of the protective cover.

[0019] A further solution is that the protective cover also includes an air outlet grille arranged at the air outlet of the protective cover, and the air outlet grille is arc-shaped; the air outlet grille, the first guide wall and the second guide wall are arranged circumferentially, the first air guide plate and the second air guide plate are arranged circumferentially, and the protective cover, the first air guide plate and the second air guide plate are arranged coaxially.

[0020] As can be seen, the air deflectors of existing portable air conditioners are usually installed on the outside of the air conditioner, in a position accessible to human hands. They are easily damaged by children's frequent manual rotation, posing a certain safety hazard. However, the present invention provides an air outlet grille at the air outlet of the protective cover to prevent external forces from damaging the air deflector and prevent hands from reaching into the air duct, thereby improving product safety. The integrated appearance is more aesthetically pleasing than traditional air deflectors.

[0021] A further solution is that the central angle corresponding to the first air deflector is equal to the central angle corresponding to the first guide wall; and / or the central angle corresponding to the second air deflector is equal to the central angle corresponding to the second guide wall.

[0022] A further solution is that the sum of the central angles corresponding to the first air guide plate and the second air guide plate is α, the central angle corresponding to the air outlet grille is β, and α and β satisfy the following relationship: 90°<β≤α<180°.

[0023] It can be seen that it is possible to close and open the air outlet and achieve the best air supply effect. In addition, when the β angle is less than or equal to 90°, it is impossible to ensure a good top air outlet or front air outlet effect; when the α angle is greater than or equal to 180°, the front air outlet mode will cause the air guide plate to block the air outlet to a certain extent.

[0024] A preferred solution is that a slide rail is provided on the inner wall of the protective cover, the slide rail is provided on the end wall of the protective cover, and at least one of the first air guide plate and the second air guide plate is in sliding cooperation with the slide rail.

[0025] A further solution is that a first guide portion is provided at the end of the first air guide plate, the first guide portion protrudes outward from the end wall of the first air guide plate, and the first guide portion is slidably connected to the corresponding slide rail; and / or a second guide portion is provided at the end of the second air guide plate, the second guide portion protrudes outward from the end wall of the second air guide plate, and the second guide portion is slidably connected to the corresponding slide rail.

[0026] It can be seen that by providing the guide portion, the contact area between the air guide plate and the protective cover is reduced, thereby reducing the friction between the two, ensuring the smoothness of the air guide plate's rotation process, and preventing excessive friction from generating noise.

[0027] A further solution is that at least one end of the first air guide plate is provided with two or more first guide portions, and the first guide portions located at the same end of the first air guide plate are arranged at intervals along the width direction of the first air guide plate; and / or at least one end of the second air guide plate is provided with two or more second guide portions, and the second guide portions located at the same end of the second air guide plate are arranged at intervals along the width direction of the second air guide plate.

[0028] It can be seen that the provision of multiple guide parts can ensure the stability of the connection between the air guide plate and the protective cover.

[0029] A preferred solution is that the number of slide rails is more than two, and at least one slide rail is provided at both ends of the protective cover in the length direction. The two ends of the first air guide plate are respectively slidably connected to the corresponding slide rails, and the two ends of the second air guide plate are respectively slidably connected to the corresponding slide rails.

[0030] It can be seen that the slide rails are respectively provided at both ends of the protective cover, which can achieve stable support for both ends of the air guide plate, thereby ensuring the smooth rotation of the air guide plate.

[0031] A preferred solution is that in the front air outlet mode, the first air guide plate is in the first open position and the second air guide plate is in the second closed position; and / or in the top air outlet mode, the first air guide plate is in the first closed position and the second air guide plate is in the second open position; and / or in the full air outlet mode, the first air guide plate is in the first open position and the second air guide plate is in the second open position.

[0032] It can be seen that by switching the position of each air guide plate, various air outlet modes can be achieved, thereby meeting the different needs of users and improving user comfort.

[0033] A preferred solution is that, in the wind sweeping mode, the first wind guide plate and the second wind guide plate swing synchronously and the relative position therebetween remains unchanged.

[0034] To achieve the second purpose mentioned above, the present invention provides an air outlet device, comprising a housing, a fan and the above-mentioned air guide mechanism, wherein the fan is located in the housing and the air guide mechanism is arranged at the air outlet of the housing.

[0059] See also Figures 1 to 3 The air outlet device of this embodiment is a mobile air conditioner, which includes a shell 1, a fan 2, a volute 3 and an air guide mechanism 4. The fan 2 and the volute 3 are located in the shell 1, and the air guide mechanism 4 is arranged at the air outlet 11 of the shell 1.

[0060] See also Figures 2 to 8The air guide mechanism 4 includes a protective cover 5, a first air guide component 6 and a second air guide component 7.

[0061] The protective cover 5 is cylindrical, and its cross-section is defined by a major arc and a chord. A protective cover air inlet 51 and a protective cover air outlet 52 are defined on the peripheral wall of the protective cover 5. The peripheral wall of the protective cover 5 includes a first guide wall 53 and a second guide wall 54 spaced apart along the circumference of the protective cover 5. The top edge 531 of the first guide wall 53 and the top edge 541 of the second guide wall 54 define the protective cover air outlet 52, while the bottom edge 532 of the first guide wall 53 and the bottom edge 542 of the second guide wall 54 define the protective cover air inlet 51. The protective cover air inlet 51 is sealedly connected to the air outlet 31 of the volute 3. The protective cover 5 also includes an arc-shaped air outlet grille 55 disposed at the protective cover air outlet 52. The air outlet grille 55, the first guide wall 53, and the second guide wall 54 are arranged co-circumferentially and are integrally formed.

[0062] The shield air outlet 52 includes a first air outlet portion 521 and a second air outlet portion 522 arranged along the circumference of the shield 5. The first air guide assembly 6 includes a first air guide plate 61 and a first driving member 62. The first driving member 62 can drive the first air guide plate 61 to swing along the circumference of the shield 5 between a first closed position and a first open position. In the first closed position, the first air guide plate 61 covers the first air outlet portion 521. In the first open position, the first air guide plate 61 opens the first air outlet portion 521.

[0063] The second air guide assembly 7 includes a second air guide plate 71 and a second driving member 72. The second driving member 72 can drive the second air guide plate 71 to swing along the circumference of the protective cover 5 between a second closed position and a second open position. In the second closed position, the second air guide plate 71 covers the second air outlet 522. In the second open position, the second air guide plate 71 opens the second air outlet 522. The first driving member 62 and the second driving member 72 are both motors.

[0064] The first air guide plate 61 and the second air guide plate 71 both extend along the length direction of the protective cover 5 and are arranged along the circumference of the protective cover 5 . The air outlet 41 of the air guide mechanism 4 is surrounded by the first air guide plate 61 and the second air guide plate 71 .

[0065] The first air guide plate 61 and the second air guide plate 71 both include a plate body 81 and a connecting portion 82. The cross-section of the plate body 81 is arc-shaped. The connecting portion 82 is close to the end of the plate body 81 and extends outward from the inner circumferential wall of the plate body 81 along the radial direction of the plate body 81. An installation portion 83 is provided at one end of the connecting portion 82 away from the plate body 81, and the installation portion 83 cooperates with the drive shaft 91 of the corresponding drive member.

[0066] The plate body 81 of the first air guide plate 61 and the plate body 81 of the second air guide plate 71 are arranged on the same circumference, and the protective cover 5, the first air guide plate 61 and the second air guide plate 71 are arranged on the same axis. Figure 9 and Figure 10 As shown, the gap H between the plate body 81 of the first air guide plate 61 and the plate body 81 of the second air guide plate 71 and the protective cover 5 is in the range of 1 mm to 3 mm. By properly designing the gap between the plate body 81 of the air guide plate and the protective cover 5, the smooth movement of the air guide plate is ensured.

[0067] The connecting portion 82 of the first air deflector 61 and the connecting portion 82 of the second air deflector 71 are respectively disposed at opposite ends of the lengthwise direction of the protective cover 5. Both connecting portions 82 are fan-shaped, each having a first radial edge 821 and a second radial edge 822. Each plate body 81 has a first plate edge 811 and a second plate edge 812, which are respectively disposed on opposite sides of the plate body 81 in the widthwise direction. The first radial edge 821 extends from the outer peripheral wall of the mounting portion 83 to the first plate edge 811, and the second radial edge 822 extends from the outer peripheral wall of the mounting portion 83 to the second plate edge 812. The fan-shaped connecting portion 82 improves the stability of the connection between the connecting portion 82 and the plate body 81, facilitating the transmission of driving force from the connecting portion 82 to the plate body 81.

[0068] An axial hole 56 is formed on the end wall 50 of the protective cover 5. A mounting portion 83 extends outward from the surface of the connecting portion 82 along the length of the protective cover 5. A drive shaft 91 corresponding to the mounting portion 83 is rotatably engaged with the axial hole 56. A mating protrusion 92 is provided on the outer peripheral wall of the drive shaft 91. A first limiting protrusion 57 and a second limiting protrusion 58 are provided on the outer surface of the end wall 50 of the protective cover 5 near the axial hole 56. The mating protrusion 92 is located between the first limiting protrusion 57 and the second limiting protrusion 58 to limit the rotation angle of the corresponding drive shaft 91. The mating protrusion 92 on the drive shaft 91 cooperates with the two limiting protrusions on the protective cover 5 to limit the rotation angle of the air deflector, thereby preventing the air deflector from rotating excessively and causing airflow obstruction or failure to close the air outlet of the air guide mechanism 4.

[0069] The central angle corresponding to the first air deflector 61 is equal to the central angle corresponding to the first guide wall 53, and the central angle corresponding to the second air deflector 71 is equal to the central angle corresponding to the second guide wall 54. Thus, when the first air deflector 61 is in the closed position, the first air deflector 61 overlaps with the first guide wall 53, and when the second air deflector 71 is in the closed position, the second air deflector 71 overlaps with the second guide wall 54.

[0070] See also Figure 11 and Figure 12The sum of the central angles of the first air guide plate 61 and the second air guide plate 71 is α, and the central angle of the air outlet grille 55 is β. α and β satisfy the following relationship: 90°<β≤α<180°. In this way, the air outlet can be closed and opened and the best air supply effect can be achieved. Figure 13 As shown, when the central angle β of the air outlet grille 55 is less than or equal to 90°, it is impossible to ensure a good top air outlet or front air outlet effect, such as Figure 14 As shown, when the sum of the central angles corresponding to the first air guide plate 61 and the second air guide plate 71 is greater than or equal to 180°, the air guide plates will block the air outlet to a certain extent in the front air outlet mode.

[0071] Two slide rails 59 are provided on the inner wall of the protective cover 5. The two slide rails 59 are respectively provided on the end walls 50 at both ends of the longitudinal direction of the protective cover 5.

[0072] On the upper side, both ends of the first air guide plate 61 are slidably connected to the two slide rails 59 respectively, and both ends of the second air guide plate 71 are slidably connected to the two slide rails 59 respectively.

[0073] Both ends of the plate body 81 of the first air deflector 61 are provided with first guide portions 611. The first guide portions 611 protrude outward from the end wall of the first air deflector 61 and are slidably connected to the corresponding slide rails 59. Both ends of the second air deflector 71 are provided with second guide portions 711. The second guide portions 711 protrude outward from the end wall of the second air deflector 71 and are slidably connected to the corresponding slide rails 59. The provision of the guide portions reduces the contact area between the air deflector and the protective cover 5, thereby reducing friction between the two, ensuring smooth rotation of the air deflector and preventing noise caused by excessive friction.

[0074] Two or more first guide portions 611 are provided at both ends of the first air guide plate 61, and the first guide portions 611 located at the same end of the first air guide plate 61 are spaced apart along the width direction of the first air guide plate 61. Two or more second guide portions 711 are provided at both ends of the second air guide plate 71, and the second guide portions 711 located at the same end of the second air guide plate 71 are spaced apart along the width direction of the second air guide plate 71. The provision of multiple guide portions can ensure the stability of the connection between the air guide plate and the protective cover 5. The first guide portion 611 and the second guide portion 711 are both clearance-matched with the slide rail 59, and the clearance is within the range of 0.5 mm to 1 mm. In addition, in order to further reduce the friction between the first air guide plate 61 and the second air guide plate 71 and the slide rail 59, the ends of the first guide portion 611 and the second guide portion 711 can be configured to be spherical crown-shaped, or rollers can be installed on each guide portion.

[0075] See also Figures 15 to 18The mobile air conditioner of this embodiment has a front air outlet mode, a top air outlet mode, a full air outlet mode and a sweeping air outlet mode. Figure 15 As shown, in the front air outlet mode, the first driving member 62 drives the first air guide plate 61 to swing to the first open position, and the second driving member 72 drives the second air guide plate 71 to swing to the second closed position. Figure 16 As shown, in the top air outlet mode, the first driving member 62 drives the first air guide plate 61 to swing to the first closed position, and the second driving member 72 drives the second air guide plate 71 to swing to the second open position. Figure 17 As shown, in the full air outlet mode, the first driving member 62 drives the first air guide plate 61 to swing to the first open position, and the second driving member 72 drives the second air guide plate 71 to swing to the second open position. In the sweeping mode, the first driving member 62 drives the first air guide plate 61 to swing, and the second driving member 72 drives the second air guide plate 71 to swing. The first air guide plate 61 and the second air guide plate 71 swing synchronously and the relative position between the two remains unchanged. Figure 18 As shown, when the mobile air conditioner is turned off, the first air guide plate 61 is in the first closed position, and the second air guide plate 71 is in the second closed position. The first air guide plate 61 and the second air guide plate 71 are connected and cover the entire shield air outlet 52. By switching the positions of the air guide plates, various air outlet modes can be achieved, thereby meeting the different needs of users and improving user comfort.

[0076] As can be seen from the above, by providing the first and second air guide plates, the size and direction of the air outlet can be flexibly adjusted by adjusting the relative position of the first and second air guide plates, thereby achieving changes in air volume, controlling the air supply distance, and improving user comfort. In addition, compared to the single air guide plate of the prior art, the provision of a protective cover blocks the airflow from both ends of the air guide plate. The airflow does not diverge toward the side of the air supply direction, but is instead concentrated toward the end of the air outlet of the air guide mechanism for air supply. At the same time, the air outlet of the air guide mechanism formed by the two air guide plates has the effect of gathering wind, which can increase the air supply distance.

[0077] Finally, it should be emphasized that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
