DETAILED DESCRIPTION

[0054] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings, and "multiple" generally includes at least two, but does not exclude the inclusion of at least one.

[0056] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0057] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such a product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0058] The air outlet and wind sweeping components of the existing air conditioners are currently unable to effectively disturb the air outlet, resulting in a poor user experience. The present invention designs a new type of air guide motion mechanism by improving the structure of the air conditioner. Through structural optimization and innovation, the angle of the fan blades can be controlled to form an integrated large air guide plate structure with a compact structure and a small volume. The angle of the fan blades can also be controlled to realize a double-layer transformable combined spoiler and wind sweeping motion mechanism, which increases the turbulence of the air outlet and increases the comfort of the air duct. Through the transformation of the motion mechanism, there are different wind sweeping modes and different spoiler levels, giving users more choices. In addition, the motion superposition of the motion mechanism can enable the upper and lower low-speed wind sweeping plus left and right spoiler air supply, and the multi-dimensional spoiler air supply mode, which increases the spoiler wind feeling range, enhances the spoiler effect, and makes the wind feel more comfortable.

[0059] To further illustrate the technical solution of the present invention, Figure 1-Figure 12 As shown, the following specific embodiments are provided.

[0060] Example 1

[0061] like Figure 1-Figure 4 As shown, in this embodiment, an air conditioner is provided, the air conditioner comprising:

[0062] A housing having an air outlet;

[0063] The wind guide component includes: a wind sweeping blade component 6 and a driving component; the wind sweeping blade component 6 can be set at the air outlet so as to be flipped up and down, and the wind sweeping blade component 6 includes: an outer wind sweeping blade 23 and an inner wind sweeping blade 19 which can be flipped left and right respectively and arranged in parallel; the driving component includes: a first driving mechanism for driving the wind sweeping blade component 6 to flip up and down, and a second driving mechanism for driving the outer wind sweeping blade 23 and the inner wind sweeping blade 19 to flip left and right.

[0064] In this embodiment, the wind guide assembly is provided with two layers of sweeping blades, each layer of sweeping blades can rotate independently or simultaneously, and by adjusting the angles of the inner and outer sweeping blades, it can be deformed into an integrated large wind guide plate structure, which can be flipped up and down by using the first driving mechanism. Each sweeping blade has a compact structure and a small volume. When it is changed into an integrated wind guide plate structure, it is similar to the existing integrated wind guide plate wind guiding method; it can also form a double-layer transformable combined spoiler sweeping motion mechanism by adjusting the angles of the inner and outer sweeping blades. After the inner and outer sweeping blades are swung or fixed at a preset angle, the turbulence of the outlet air can be increased, and the comfort of the air duct can be increased. The sweeping blade can add different sweeping modes and different spoiler levels to the air conditioner through the transformation of the motion mechanism, so that users have more choices. In addition, the motion superposition of the motion mechanism can make the upper and lower low-speed sweeping air plus the left and right spoiler air supply, the multi-dimensional spoiler air supply mode, increase the spoiler wind feeling range, enhance the spoiler effect, and make the wind feel more comfortable.

[0065] It should be noted that the up-down flipping and left-right flipping in this embodiment are relative to when a person faces the front of the air conditioner, and the fan blade angle can be adjusted to multiple angles of up-down, left-right, and right-left.

[0066] In some optional modes, the driving assembly further includes a third driving mechanism 7. The third driving mechanism 7 can drive the sweeping blade assembly 6 to extend / retract to the air outlet. This mode can adjust and control the position distance between the sweeping blade assembly 6 and the air outlet, and cooperate with the sweeping blade that can be adjusted to flip left and right, further enriching the mode of controlling the turbulence degree of the air outlet of the air conditioner in different sweeping modes.

[0067] In this embodiment, the wind sweep blade assembly 6 further includes: a wind sweep plate bracket 9 arranged at the air outlet, wherein: the side of the wind sweep plate bracket 9 facing the air outlet is the inner side of the frame body, and the inner side of the frame body is installed with the inner wind sweep blade 19; the side of the wind sweep plate bracket 9 facing away from the air outlet is the outer side of the frame body, and the outer side of the frame body is installed with the outer wind sweep blade 23. That is, one wind sweep plate bracket 9 is used to fix the inner and outer wind sweep blades at the same time.

[0068] Preferably, the wind sweeping plate bracket 9 adopts a rectangular frame structure, and a plurality of blade mounting holes are provided on the inner and outer sides of the frame, wherein the plurality of blade mounting holes are evenly distributed along the two corresponding long sides of the frame. This design method is to coordinate with the long sides of the wind sweeping plate bracket 9 correspondingly arranged in the length direction of the air outlet for wind sweeping, so that the inner and outer wind sweeping blades can be flipped left and right. It should be noted that when a person faces the air outlet, the length direction of the air outlet is horizontal, and the width is vertical. At this time, the corresponding wind sweeping blade can be regarded as being arranged vertically relative to the wind sweeping plate bracket 9.

[0069] Preferably, the outer layer sweeping blades 23 and / or the inner layer sweeping blades 19 adopt a long strip plate-like structure. The side wall of the long strip plate-like structure includes a first plate surface and a second plate surface, the first plate surface is a plane, and the second plate surface is a curved surface, and the plane and the curved surface together form the side wall of the long strip plate-like structure. The curved surface is an outward convex curved surface, and the curvature of the curved surface gradually decreases along the first end to the second end of the cross section of the long strip plate-like structure. It should be noted that the first end of the cross section can be understood as the junction of the curved surface and one side of the plane. Since the curvature is variable, the first end of the cross section corresponds to the thick end of the sweeping blade (the thick end of the outer layer sweeping blade or the thick end of the inner layer sweeping blade); the second end of the cross section can be understood as the junction of the curved surface and the other side of the plane, corresponding to the thin end of the sweeping blade.

[0070] In this embodiment, the inner and outer sweeping blades that can be turned left and right can be combined to set corresponding fixed angles to achieve turbulence on the outgoing air. Preferably, the outer sweeping blade 23 has an outer first working position perpendicular to the outlet direction of the air outlet, an outer second working position with the thick end of the outer sweeping blade 23 facing the inside of the air outlet, and an outer third working position with the thick end of the outer sweeping blade 23 facing the outside of the air outlet; the inner sweeping blade 19 has an inner first working position perpendicular to the outlet direction of the air outlet, an inner second working position with the inner sweeping blade 19 facing the outside of the air outlet, and an inner third working position with the thick end of the inner sweeping blade 19 facing the inside of the air outlet.

[0071] Since the wind sweeping blade has a curved surface and a flat surface, when the outer wind sweeping blade 23 is adjusted to the outer second working position and the inner wind sweeping blade 19 is adjusted to the inner second working position, the thick end of the outer wind sweeping blade 23 and the thick end of the inner wind sweeping blade 19 are spliced ​​to form a spoiler wind sweeping blade with a shuttle-shaped cross section. That is, the spoiler wind sweeping blade has a cross section that is approximately circular when it is close to the central axis, and gradually becomes flat when it is close to the second end of the cross section.

[0072] In some optional ways, the third driving mechanism 7 includes: a gear box assembly; a driving rack, the first end of the driving rack is connected to the gear box assembly, and the second end of the driving rack is connected to the wind sweeping plate bracket 9; a lifting motor arranged in the gear box assembly and a transmission gear connecting the lifting motor and the driving rack. At this time, optionally, in this embodiment, the first driving mechanism includes: a first driving motor 10 arranged at the second end of the driving rack, and the first driving motor 10 can drive the wind sweeping plate bracket 9 to flip up and down at the air outlet.

[0073] In some optional embodiments, the wind sweep blade assembly 6 further includes: an outer layer transmission connecting rod 26 connected to the outer layer wind sweep blade 23; and an inner layer transmission connecting rod 18 connected to the inner layer wind sweep blade 19.

[0074] When the air conditioner is a wall-mounted cabinet, it can be designed to have upper and lower air outlets. In this case, the air outlets include: an upper air outlet arranged at the top of the shell and a lower air outlet arranged at the bottom of the shell; accordingly, both the upper air outlet and the lower air outlet are provided with air guide components.

[0075] In addition, the air conditioner housing in this embodiment includes: an air inlet bottom shell located at the rear of the housing, which is formed with an air inlet; a panel 3 located at the front of the housing; and an air outlet bracket 5 at the top and / or bottom.

[0076] In this embodiment, the wind sweeping component is designed as a double-layer transformable combined spoiler wind sweeping motion mechanism to increase the turbulence of the air outlet and increase the comfort of the air duct; different wind sweeping methods corresponding to different modes of the air conditioner are used to give users more choices. The air conditioner drives the wind sweeping blades to flip up and down on the wind sweeping plate bracket to sweep the air at a low speed. At the same time, the wind sweeping blades are driven independently to supply spoiler air to the left and right. The multi-dimensional spoiler air supply mode makes the wind feel more comfortable. Furthermore, the third driving mechanism 7 is used to adjust the lifting height to further increase the spoiler level, providing users with a variety of options.

[0077] Example 2

[0078] In order to achieve the above purpose, the present invention also provides another better embodiment of the air conditioner based on Example 1, wherein to ensure the turbulence effect, some driving mechanisms in this embodiment can adopt two groups and be symmetrically arranged on the left and right sides of the air guide assembly.

Figure 2 As shown in the figure, it is an air outlet diagram. The overall wall-mounted cabinet adopts the rear air intake and top and bottom air outlet mode. Figure 4As shown, it is an exploded view of the wind guide assembly, which includes: a bracket 8 that can be used as a support and decoration for the inner and outer layer wind sweeping blade driving mechanism; a wind sweeping plate bracket 9 supports the inner and outer layer wind sweeping blades to rotate; a first driving motor 10 is used to drive the wind sweeping plate assembly to flip up and down; a left driving rack 11 is provided on the left side of the wind sweeping plate bracket 9 to drive the wind guide plate assembly to lift and lower as a whole; a left transmission gear 12 provided on the left side of the wind guide plate is used to drive the left driving rack 11 on the left side of the wind sweeping plate bracket 9; a left driving lifting motor 13 drives the left transmission gear 12; a gear box assembly 14 is used as a gear Wheel and rack assembly box; gear box assembly 2 15 serves as a motor mounting plate and a gear box sealing cover; inner layer wind sweeping plate driving motor 16 serves as a driving source for inner layer wind sweeping blades 19; inner transmission crankshaft 17 serves as a transmission part for inner layer wind sweeping blades 19; inner layer transmission connecting rod 18 serves as a rotation execution connecting rod for inner layer wind sweeping blades 19; inner layer wind sweeping blades 19; right driving rack 20 of wind sweeping plate bracket 9; right driving lifting motor 21; right transmission gear 22; outer layer wind sweeping blades 23; outer layer wind sweeping driving motor 24; outer transmission crankshaft 25; outer layer transmission connecting rod 26.

[0080] Based on the above embodiment, the present invention also provides a control method for an air conditioner. The control method includes: when the air conditioner is running, the air guide assembly can be adjusted to a preset height, and then the air sweeping blade assembly can be turned on to supply air. During the air supply process, the following can be done:

[0081] The outer sweeping blades are adjusted to a direction perpendicular to the air outlet direction or to a direction parallel to the air outlet direction, or are swung left and right at a first preset swing speed;

[0082] and / or, adjusting the inner sweeping blades to a direction perpendicular to the air outlet direction of the air outlet or to a direction horizontal to the air outlet direction of the air outlet, or swinging left and right at a second preset swing speed;

[0083] And / or, the wind sweeping blade assembly is adjusted to a preset angle or swung up and down at a third preset swing speed.

[0084] Based on the above control method, in this embodiment, different spoiler and wind sweeping modes that can be combined by the air guide assembly through the movement of the motion mechanism are further provided for the air guide plate adjustment process, as follows.

[0085] Ordinary large air deflector mode: Mode 1: Fig.11 The common large air guide plate mode is shown. The common large air guide plate mode is formed by rotating the outer air sweeping blade 23 and the inner air sweeping blade 19 to a horizontal position to become a common air guide plate mode. The middle is a hollow belt. At the same time, the whole air guide plate is moved by the lifting module to Fig.11 Position, and realize up and down sweeping by rotating the up and down sweeping modules. Mode 2: Fig.12The ordinary large wind guide plate mode has a spoiler effect and a wind sweeping mode, with double-layer left and right wind sweeping plates. The outer layer is horizontally closed to compress the wind, and the inner layer is perpendicular to the outer layer. The curved surface of the inner layer wind sweeping blade 19 can play a spoiler role. In addition, the left and right wind sweeping plates are driven by a motor to swing to perform left and right spoiler sweeping.

[0086] Cylindrical spoiler mode: Figure 5 , Figure 6 , Figure 7 The cylindrical spoiler mode is realized by rotating the outer sweeping blades 23 and the inner sweeping blades 19 to form an intermediate cylinder. The effect of the cylindrical spoiler is affected by the distance between the spoiler cylinder and the air outlet. Within a certain range, the farther the cylinder is from the air outlet, the more effective it is. In addition, the cylindrical spoiler mode and the ordinary large air guide plate mode can be superimposed to expand the effect and range of the spoiler.

[0087] Double-layer wind-sweeping spoiler mode: Figure 8 , Fig. 9 , Fig.10 The double-layer spoiler mode is mainly to increase the turbulence of the airflow through the two layers of S-shaped wind sweeping plates, thereby reducing the wind feeling and improving comfort. Similarly, the double-layer wind sweeping spoiler mode and the ordinary large wind guide plate mode can be superimposed to expand the effect and range of the spoiler.

[0088] Through the transformation of the motion mechanism, there are different wind sweeping modes and different spoiler levels, giving users more choices. The motion of the motion mechanism is superimposed, with low-speed air sweeping up and down and spoiler air supply on the left and right, and multi-dimensional spoiler air supply mode, which increases the range of spoiler wind feeling, enhances the spoiler effect, and makes the wind feeling more comfortable.

[0089] The exemplary embodiments of the present disclosure are specifically shown and described above. It should be understood that the present disclosure is not limited to the detailed structures, configurations or implementations described herein; on the contrary, the present disclosure is intended to cover various modifications and equivalent configurations included in the spirit and scope of the appended claims.
