Detailed Implementation

[0041] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0043] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0044] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0045] In existing air conditioners, micro-hole air outlets and various air diffusion functions have been introduced to avoid the air conditioner venting directly onto the human body; however, the micro-hole air outlet solution has a greater obstruction effect on airflow; when guiding air through a flexible air guide plate, the material requirements of the air guide plate are high, and it is impossible to achieve precise control of the amount of material deformation; when dispersing air through air diffusion components, the adjustment structure is designed to be more complex in order to obtain more air diffusion angles.

[0046] This invention creatively provides an air guiding device for an air conditioner. The air conditioner includes a housing with an air outlet. The air guiding device is disposed at the air outlet and includes an air guide plate. A channel group is formed inside the air guide plate. The channel group includes multiple channels, which form a fluid oscillation structure. Alternatively, the air guiding device includes an air guide plate and an oscillator. The oscillator is disposed on the air guide plate and has multiple channels, which form a fluid oscillation structure. This invention has no moving parts and a simple structure, solving the problems of complex structure and significant air obstruction in existing air guiding devices.

[0047] Example 1

[0048] <Air guiding device>

[0049] As shown in Figure 1 to Figure 4b As shown, this embodiment provides an air guiding device for an air conditioner. The air conditioner includes an indoor unit 5 and an outdoor unit. The indoor unit 5 includes a housing 51, which has an air outlet and a return air outlet. A return air duct is formed inside the housing 51 between the air outlet and the return air outlet. An indoor heat exchanger 52 and a fan 53 are installed inside the return air duct. Under the action of the fan 53, indoor air enters the return air duct through the return air outlet and exchanges heat with the indoor heat exchanger 52. The air guiding device is installed at the air outlet and includes an air guide plate 1. The air guide plate 1 can be controlled to rotate. A channel group is formed inside or on the surface of the air guide plate 1. The channel group includes multiple channels, and the multiple channels form a fluid oscillation structure 3.

[0050] With no moving parts and a simple structure, it solves the problems of complex structure and significant air obstruction in existing air guiding devices. It can divide the air, with one part passing along the surface of the air guide plate 1 and the other part passing along the fluid oscillation structure 3 to form an oscillating airflow. It has the advantages of self-excited oscillation and self-excited maintenance, which can avoid air blowing directly on the human body, improve comfort, and solve the problems of existing air conditioners blowing air directly on the human body and having a small air delivery range.

[0051] To address the issue of poor airflow guidance when there are too few fluid oscillation structures 3, this embodiment proposes that multiple fluid oscillation structures 3 be provided, arranged sequentially and at intervals along the length of the air guide plate 1, and that multiple channels of each fluid oscillation structure 3 extend along the width of the air guide plate 1; the multiple fluid oscillation structures 3 have the same structure or two adjacent fluid oscillation structures 3 have different structures; the spacing of the multiple fluid oscillation structures 3 along the length of the air guide plate 1 or the spacing along the width of the air guide plate 1 can be the same or different, and by adjusting the spacing of the multiple fluid oscillation structures 3 along the length of the air guide plate 1 or the spacing along the width of the air guide plate 1, the oscillating airflow of the fluid oscillation structures 3 can have different phases; when the structures of the multiple fluid oscillation structures 3 are different, the oscillating airflow can have different oscillation frequencies.

[0052] like Figure 2a , Figure 3a and Figure 3b As shown, in response to the problem that the oscillation effect is not obvious due to the unreasonable design of the fluid oscillation structure 3, this embodiment proposes that multiple channels include an air inlet channel 31, a main channel 32 and an air outlet channel 33 arranged in sequence. The air inlet channel 31 connects the air inlet side of the air guide plate 1 with the main channel 32, and the air outlet channel 33 connects the main channel 32 with the air outlet side of the air guide plate 1.

[0053] An air inlet constriction structure 341 is formed at the connection between the air inlet channel 31 and the main channel 32, and an air outlet constriction structure 342 is formed at the connection between the air outlet channel 33 and the main channel 32; the average flow area of ​​the air inlet channel 31 and the average flow area of ​​the air outlet channel 33 are both smaller than the average flow area of ​​the main channel 32.

[0054] Furthermore, the main channel 32 includes a first wall surface 321 and a second wall surface 322; the multiple channels also include a first feedback channel 351 and a second feedback channel 352, which are arranged side by side on both sides of the main channel 32, with the first feedback channel 351 on the same side as the first wall surface 321 and the second feedback channel 352 on the same side as the second wall surface 322; the two ends of the first feedback channel 351 are respectively connected to the air inlet channel 31 and the air outlet channel 33, and the two ends of the second feedback channel 352 are respectively connected to the air inlet channel 31 and the air outlet channel 33.

[0055] The air in the main channel 32 has a first state of moving towards the first wall 321 and a second state of moving towards the second wall 322; a portion of the air flowing through the main channel 32 can re-enter the main channel 32 through the first feedback channel 351 or the second feedback channel 352, so that the air flowing through the main channel 32 moves alternately between the first state and the second state.

[0056] Specifically, when air enters the fluid oscillation structure 3 from the air inlet channel 31, it flows against one side wall of the main channel 32. Upon reaching the end of the main channel 32, part of the air flows out from the air outlet channel 33, while the other part flows back to the main channel 32 along the first feedback channel 351 and acts on the mainstream air within the main channel 32, creating a large recirculation zone between the mainstream air and the other side wall of the main channel 32. When the tributary air flowing along the first feedback channel 351 has sufficient pressure to overcome the wall adsorption, the mainstream air is pushed against the other side wall of the main channel 32 and adheres to it. Therefore, the mainstream air moves back and forth between the two side walls of the main channel 32. In this way, the jet adheres back and forth to the two side walls of the main channel 32, generating a periodically oscillating jet at the outlet, which is then discharged through the air outlet channel 33.

[0057] To address the problem that current air guiding devices cannot achieve directional air delivery, resulting in a narrow range of application, this embodiment proposes that the air guiding device also includes a baffle 4, which is disposed on the air inlet side of the air guiding plate 1 and can open or close the air inlet end of the air inlet channel 31.

[0058] When a gentle breeze is needed, the baffle 4 opens the air inlet end of the air inlet channel 31; part of the air is discharged through the outer contour surface of the air guide plate 1, and part of the air is discharged through the fluid oscillation structure 3.

[0059] When the air guide device is needed to achieve directional air supply, the baffle 4 closes the air inlet end of the air inlet duct; the air is discharged through the air guide plate 1.

[0060] Figure 5a and Figure 5b The images show simulated air velocity cloud maps of the air discharged from the air guide device through the fluid oscillation structure 3 at different times. It can be seen that the direction of the oscillating airflow changes, and the outlet velocity is greater than the inlet velocity. The airflow sweep angle is large and the range is wide.

[0061] Air Conditioning

[0062] like Figures 6 to 7b As shown, this embodiment also proposes an air conditioner, including an indoor unit 5, which includes an indoor unit 5 and an outdoor unit. The indoor unit 5 includes a housing 51 and an air guide device for air conditioning as described in any of the above embodiments; the housing 51 has an air outlet, and the air guide device is disposed at the air outlet.

[0063] Example 2

[0064] Unlike Example 1, as Figure 2bAs shown, to address the problem of insignificant oscillation effect caused by unreasonable design of the fluid oscillation structure 3, this embodiment further proposes that the multiple channels also include a first vibration channel 361 and a second vibration channel 362, which are arranged side by side on both sides of the air inlet constriction structure 341. The first vibration channel 361 is connected to the air inlet channel 31 and the main channel 32 through the air inlet constriction structure 341, and the second vibration channel 362 is connected to the air inlet channel 31 and the main channel 32 through the air inlet constriction structure 341. A portion of the air discharged from the air inlet channel 31 enters the main channel 32 and is deflected towards one side wall of the main channel 32, thereby causing pressure fluctuations in the air in the first vibration channel 361 and the air in the second vibration channel 362, causing the air in the main channel 32 to deflect. By utilizing the first vibration channel 361 and the second vibration channel 362 on both sides of the main channel 32, pressure fluctuations are generated when the jet adheres to the wall, thereby driving the air in the main channel 32 to deflect.

[0065] Example 3

[0066] Unlike Example 1, as Figure 2c As shown, in response to the problem that the oscillation effect is not obvious due to the unreasonable design of the fluid oscillation structure 3, this embodiment proposes that there are two air inlet channels 31, which are arranged side by side on both sides of the main channel 32; the two streams of air enter the main channel 32 through the two air inlet channels 31 respectively and merge, and are discharged through the air outlet channel 33; after the two jets of the two air inlet channels 31 undergo a complex coupling and mixing process in the main channel 32, they form an oscillating jet at the air outlet end of the air outlet channel 33.

[0067] Example 4

[0068] <Air guiding device>

[0069] Unlike Embodiment 1, the air guide plate 1 has a first position, a second position, and a third position in its rotation direction;

[0070] When the air guide plate 1 is in the first position, a portion of the air from the air outlet is discharged through the upper wall of the outer contour of the air guide plate 1, and the other portion of the air from the air outlet is discharged through the fluid oscillation structure 3.

[0071] When the air guide plate 1 is in the second position, a portion of the air from the air outlet is discharged through the lower wall surface of the outer contour of the air guide plate 1, and the other portion of the air from the air outlet is discharged through the fluid oscillation structure 3.

[0072] When the air guide plate 1 is in the third position, the first part of the air from the air outlet is discharged through the upper wall of the outer contour of the air guide plate 1, the second part of the air from the air outlet is discharged through the fluid oscillation structure 3, and the third part of the air from the air outlet is discharged through the lower wall of the outer contour of the air guide plate 1.

[0073] Air Conditioning

[0074] This embodiment also proposes an air conditioner, including an indoor unit 5, which includes an indoor unit 5 and an outdoor unit. The indoor unit 5 includes a housing 51 and the air guide device for the air conditioner described above. The housing 51 has an air outlet, and the air guide device is disposed at the air outlet.

[0075] The air conditioner has a cooling mode and a heating mode. When the air guide plate 1 is in the first position, the air conditioner can operate in cooling mode; when the air guide plate 1 is in the second position, the air conditioner can operate in heating mode.

[0076] It can achieve autonomous air sweeping (without moving parts), increasing the dynamic air supply range of the air conditioner; the outlet jet has a large flow rate, and the oscillating air outlet can enhance the mixing effect between airflows, which is more conducive to rapid temperature conduction, achieving rapid cooling and heating effects, and solving the problem that the air sweeping function of existing air conditioners requires moving parts, resulting in complex structure and long cooling and heating time.

[0077] Example 5

[0078] Unlike Embodiment 1, the air guiding device includes an air guiding plate 1 and an oscillator 2. The oscillator 2 is disposed on the air guiding plate 1 and has multiple channels, which form a fluid oscillation structure 3.

[0079] Example 6

[0080] Unlike Embodiment 1, the air guiding device also includes a flexible curtain, which can be rolled up and installed on the air inlet side of the air guiding plate 1 and can open or close the air inlet end of the air inlet channel 31.

[0081] When a gentle breeze is needed, the flexible curtain opens the air inlet end of the air inlet channel 31; part of the air is discharged through the outer contour surface of the air guide plate 1, and part of the air is discharged through the fluid oscillation structure 3.

[0082] When a directional airflow device is needed, the flexible curtain closes the air inlet end of the air inlet duct; the air is then discharged through the air guide plate 1.

[0083] Exemplary embodiments of the present disclosure have been specifically shown and described above. It should be understood that the present disclosure is not limited to the detailed structures, arrangements, or implementation methods described herein; the fluid oscillation structure in Embodiment 1 is preferably a Coanda swept oscillator structure, the fluid oscillation structure in Embodiment 2 is preferably a Coanda swept oscillator structure without feedback channels, and the fluid oscillation structure in Embodiment 3 is preferably a jet-coupled oscillator structure; rather, the present disclosure is intended to cover various modifications and equivalent arrangements contained within the spirit and scope of the appended claims.
