Description

Technical Field

[0002] As people's demand for indoor comfort becomes higher and higher, the air supply comfort of air conditioners has gradually become one of the important factors affecting market share.

[0003] Cold air blowing directly towards the human body is the primary reason that affects the comfort of air supply from air conditioners. In order to solve this problem, in related technologies, the air outlet of the air conditioner is set at the top to blow air upward to prevent the cold air from blowing directly towards the human body. However, this will result in less air volume being delivered to the area where the human body is active, causing serious losses in air volume and cooling capacity. At the same time, there is the problem of difficulty in compressing the air. When the air conditioner is in heating mode, heat cannot be well delivered to the area where the human body is active, and the energy utilization rate in the area where the human body is active is low.

[0004] Therefore, how to improve the air supply structure to provide a more comfortable comprehensive indoor air supply scene, while solving the problem of cold air not blowing on people and suppressing hot air, has become a problem that needs to be solved at present. Summary of the Invention

[0035] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions 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 embodiments described are only 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 making creative efforts should fall within the scope of protection of the present invention.

[0036] In order to solve the technical problem in the related art that the air supply structure is unreasonable and causes poor air supply comfort of the air conditioner, the present invention provides an air supply structure, an air conditioner and a control method for the air conditioner.

[0037] like Figures 1 to 4As shown, the present application provides an air supply structure, comprising: an air supply duct 1 and an air outlet 2 connected to the air supply duct 1, the air outlet 2 being arranged on the front side of the air supply structure; the air supply duct 1 has a top wall surface 10 and a rear side surface 20 arranged opposite to the air outlet 2; an air guide 3, the air guide 3 is rotatably arranged in the air supply duct 1, and the air guide 3 has a forward tilting state and a backward tilting state; the air supply structure has an upward air supply state and a downward pressure air supply state; when the air supply structure is in the upward air supply state, the air guide 3 is in a forward tilting state, and the air guide 3 is used to guide the airflow to the air outlet 2; when the air supply structure is in the downward pressure air supply state, the air guide 3 is in a backward tilting state, and the air guide 3 is used to guide the airflow to the rear side surface 20, and the rear side surface 20 is used to guide the airflow to the top wall surface 10, and the airflow flows out of the air outlet 2 along the top wall surface 10.

[0038] In this way, by utilizing the cooperation between the inner wall surface of the air supply duct 1 and the air guide 3, the rotation of the air guide 3 is controlled to make it in a forward tilted state or a backward tilted state, thereby controlling the direction of the airflow, and then controlling the air supply direction, so that the air supply structure has an upward air supply state and a downward air supply state.

[0039] like Figure 3 As shown, the air supply structure is in an upward air supply state, such as Figure 4 As shown, the air supply structure is in a downward pressure air supply state.

[0040] Optionally, the rear side surface 20 includes a protrusion protruding into the air supply duct 1. When the air guide 3 is in the backward tilted state, the air guide 3 is used to guide the airflow to the protrusion, and the airflow is concentrated at the protrusion and then turned to the top wall 10. In this way, the airflow is concentrated by the air guide at the protrusion of the rear curved surface, forming a high-pressure center at the protrusion. After converging into a concentrated airflow, it is forced to turn, guide through the top wall, and send downward along the top wall, thereby achieving downward pressure on the airflow.

[0041] Optionally, the top wall surface 10 is tilted downwardly toward the side of the air outlet 2. In this way, the top wall surface 10 is tilted downwardly, which is more conducive to the airflow being sent downward along the top wall surface.

[0042] Optionally, the included angle between the profile of the top wall surface 10 and the horizontal line is α, 2°≤α≤5°. In this way, by controlling the specific parameters of α, the air supply angle and the downward pressure effect can be more accurately controlled.

[0043] Preferably, α=3°.

[0044] Optionally, the top wall surface 10 is a curved surface; and / or the rear side surface 20 is a curved surface. In this way, the air flow converges and supplies air using the curved surface, which has a better effect, can reduce air flow loss, and make the air flow smoother.

[0045] Optionally, with the bottom of the profile of the rear side surface 20 as the origin, the vertical upward direction as the x-axis direction, and the horizontal forward direction as the y-axis direction, the profile of the rear side surface 20 satisfies the following equation: Where 0 mm ≤ x ≤ 180 mm, -93.5 ≤ a ≤ 94.5, 80 ≤ b ≤ 84, 91 ≤ c ≤ 93; or y = ax b , where 0 mm ≤ x ≤ 180 mm, 3 ≤ a ≤ 4.5, 0.5 ≤ b ≤ 0.7; or (xa) 2 +(yb) 2 =c 2 , where 0mm≤x≤180mm, 150≤a≤160, b=-0.75~0.8a, c=1.2~1.25a. Thus, further parameterized design of the rear side profile is performed. When the parameters are set within the above numerical range, the compatibility effects of "keeping the wind out of your body" and "suppressing the wind" can be better achieved.

[0046] After testing, it was found that after parameter optimization design, the air supply range of the air supply structure provided in this application can reach -50° to 30°, and the air supply distance can reach 9m, which can realize all-round long-distance air supply indoors.

[0047] Optionally, the air guide member 3 is an air guide plate 300, and the rotation centers of the plurality of air guide members 3 are on the same reference straight line. In this way, the effect of providing a plurality of air guide plates 300 is better.

[0048] Optionally, each air guide member 3 is parallel. Optionally, the angle between the air guide plate 300 and the reference line is β, β = 15(5-n) + m, where n is the number of grids of the air guide plate, and n is automatically adjusted according to settings or user-defined adjustment, n = 1 or 2 or 3 or 4 or 5, 48 ≤ m ≤ 52. In this way, the rotation angle of the air guide plate 300 can be adjusted by setting the number of grids n of the air guide plate, thereby adjusting the angle between the air guide plate 300 and the reference line to β, thereby changing the air supply direction.

[0049] Preferably, m = 50, and β = 15(5-n) + 50. When n = 1, β = 110; when n = 2, β = 95; when n = 3, β = 80; when n = 4, β = 65; and when n = 5, β = 50. Thus, when n = 1 and n = 2, the wind deflector 300 is in a forward tilted state, and when n = 3, n = 4, and n = 5, the wind deflector 300 is in a backward tilted state.

[0050] Optionally, the reference straight line is an oblique line, and a position of the oblique line close to the rear side surface 20 is higher than a position close to the air outlet 2 side.

[0051] Optionally, the air supply structure further comprises: a control unit, the control unit being configured to control the rotation of the air guide 3. In this way, the air guide 3 can be automatically controlled to rotate to a preset angle by the control unit.

[0052] Optionally, the air supply structure further includes a temperature sensor for monitoring the indoor temperature, denoted as Te. The control unit is further configured to compare the air conditioner's set temperature Ts with Te to obtain a temperature difference ΔT, and to control the rotation angle of the air guide 3 based on ΔT to control whether the air supply structure is in an upward air supply state or a downward air supply state, as well as the angle of the upward air supply or downward air supply. In this way, by controlling the rotation angle of the air guide 3 based on the temperature difference ΔT, both air supply comfort and cooling or heating performance can be achieved.

[0053] In a specific embodiment, Figure 1 and Figure 2 As shown, the air supply structure includes an air outlet frame 100 and a rear air shield 200. The rear air shield 200 is installed on the rear side of the air outlet frame 100. The front side of the air outlet frame 100 forms an air outlet 2. The wall surface of the rear air shield 200 facing the air outlet 2 is the rear side surface 20, and the inner wall surface of the top of the air outlet frame 100 is the top wall surface 10. The cross-sectional profile of the rear air shield 200 is the same as the profile of the rear side surface 20, and the cross-sectional profile of the top frame line of the air outlet frame 100 is the same as the profile of the top wall surface 10. The rear air shield 200 is made of a transparent material. In this way, the air supply structure is simple, low-cost, and highly comfortable. It delivers more cooling and heat to the human activity area, achieving the dual goals of comfort and energy saving.

[0054] In this specific embodiment, the angle α between the top frame line of the upper air outlet and the horizontal is 2°≤α≤5°; the angle β between the air guide plate and the lower frame line of the air outlet is β=15(5-n)+50, where n is the number of air guide plate grids, n=1, 2, 3, 4, 5; m is a fixed parameter, 48≤m≤52; the rear windshield plate 200-shaped line y, Where 0 mm ≤ x ≤ 180 mm, -93.5 ≤ a ≤ 94.5, 80 ≤ b ≤ 84, 91 ≤ c ≤ 93; or y = ax b , where 0 mm ≤ x ≤ 180 mm, 3 ≤ a ≤ 4.5, 0.5 ≤ b ≤ 0.7; or (xa) 2 +(yb) 2 =c 2 Where 0mm≤x≤180mm, 150≤a≤160, b=-0.75~0.8a, c=1.2~1.25a. When these parameter design relationships and spatial relationships are met, the compatibility of "keeping the wind out of people's eyes" and "pressing the airflow" can be better achieved. In this case, the air conditioning can deliver air within a range of -50° to 30° and a distance of up to 9m, achieving all-round, long-distance air delivery indoors.

[0055] The upper air outlet top frame line is the top frame line of the air outlet frame top 101 .

[0056] The lower frame line of the air outlet is parallel to the reference straight line.

[0057] The rear windshield 200 is made of a transparent material, which helps to enhance the aesthetics of the air outlet structure.

[0058] Optionally, the air supply structure of the present application is an upper air supply structure, the air outlet frame 100 is an upper air outlet frame, and the air outlet 2 is an upper air outlet.

[0059] like Figure 1 and Figure 2 As shown, multiple air guide plates 300 form an air guide assembly. This application utilizes a unique air guide assembly control method and curved surface convergent air supply technology, combined with a guiding upper air outlet top frame line. By controlling the angles of the air guide plates, the outlet airflow direction is controlled. The specific structure includes an upper air outlet frame, an air guide assembly, and a rear windshield plate 200. Airflow enters from the underside of the air outlet frame 100, flows sequentially through the underside of the air outlet frame 100, the air guide plates 300, the rear windshield plate 200, the air outlet frame 100 (including the top side), and finally flows out of the air outlet 2.

[0060] Based on the wall aggregation effect, this application provides an air supply solution that combines a curved airflow aggregation structure with a unique air guide plate orientation design, taking into account the dual goals of "not blowing people" and "pressing the air". When the upward air supply state is adopted (such as cooling mode), the air guide plate tilts forward, and the Figure 3 , the air is sent out through the air guide plate and the top curved surface, realizing the tilted upward air flow. When the downward pressure air supply state is adopted (such as heating mode), the air guide plate is tilted backward, and the air flow is tilted upward. Figure 4 The airflow is gathered at the convex point of the rear curved surface through the air guide plate and forms a high-pressure center. After converging into a concentrated airflow, it is forced to turn and is drained through the top curved surface. The airflow is sent down along the top curved surface to achieve downward pressure on the airflow.

[0061] The present application also provides an air conditioner, which includes the above-mentioned and the following air supply structures. The air supply duct 1 of the air supply structure includes a main air duct section and an air outlet duct section. The outlet of the main air duct section is connected to the inlet of the air outlet duct section, and the air guide 3 is arranged at the connection between the main air duct section and the air outlet duct section.

[0062] This application also provides a method for controlling an air conditioner, the air conditioner being the above-mentioned one, which has a cooling mode and a heating mode. The control method includes: obtaining the temperature difference between the indoor temperature and the air conditioner's set temperature; and, based on the temperature difference and in conjunction with whether the air conditioner is in cooling mode or heating mode, controlling the air supply structure to be in a downward pressure air supply state or an upward air supply state, and controlling the angle of the upward air supply or downward pressure air supply. In this way, the air supply direction and direction of the air supply structure are changed in conjunction with the temperature difference and the air conditioner's mode, further improving the comfort of the air conditioner, providing users with a wider range of air supply methods, and enhancing the user experience.

[0063] Optionally, the control method includes: controlling the air supply structure to be in a downward pressure air supply state or an upward air supply state, and the angle of the upward air supply or downward pressure air supply by adjusting the number n of grids of the air guide plate.

[0064] Alternatively, as Figure 5 As shown, the control method includes: S1, judging whether the air conditioner is in cooling mode; when the judgment is yes, the monitored indoor temperature is recorded as Te, the set temperature of the air conditioner is recorded as Ts, and ΔT1=Te-Ts; S2, judging whether the air conditioner is in up and down / single air outlet mode; when the judgment is no, executing S1; when the judgment is yes, executing S3; S3, judging whether the air conditioner is in up and down sweeping mode; when the judgment is yes, controlling the air guide plate 300 to sweep the air up and down; when the judgment is no, executing S4; S4, judging whether to set the number n of the air guide plate; when the judgment is yes, running according to user definition, when the judgment is no, executing S5; S5, judging whether ΔT1 is greater than or equal to the first preset value; when the judgment is yes, setting n=5 to achieve rapid cooling; when the judgment is no, setting the number n of the air guide plate to 2 to avoid direct blowing of cold air.

[0065] Alternatively, as Figure 6 As shown, the control method includes: S1, judging whether the air conditioner is in the heating mode; when the judgment is yes, the monitored indoor temperature is recorded as Te, the set temperature of the air conditioner is recorded as Ts, and ΔT2=Te-Ts; S2, judging whether the air conditioner is in the up and down / single air outlet mode; when the judgment is no, executing S1; when the judgment is yes, executing S3; S3, judging whether the air conditioner is in the up and down sweeping mode; when the judgment is yes, controlling the air guide plate 300 to sweep the air up and down; when the judgment is no, executing S4; S4, judging whether the number n of the air guide plate is set; when the judgment is yes, operating according to user definition, when the judgment is no, executing S5; S5, judging whether ΔT1 is greater than or equal to the second preset value; when the judgment is yes, setting n=5 to achieve rapid heating; when the judgment is no, setting the number n of the air guide plate to 4 to achieve hot air collection and downward delivery.

[0066] Optionally, the first preset value and the second preset value are both 5°C.

[0067] Optionally, the first preset value and the second preset value can be adjusted according to actual conditions to achieve precise temperature control.

[0068] Optionally, the number n of grids of the air guide plate can be set between 1 and 5 according to actual conditions.

[0069] The air conditioner control method provided in this application can realize multi-dimensional air supply control, meet different user needs and usage scenarios, and improve the user's comfort experience and energy saving experience "dual goals" such as Figure 5 and Figure 6When cooling (heating), the control strategy allows for multiple modes, including wind-avoidance mode, rapid cooling, rapid heating, hot air collection and downward delivery, and user-defined. Except for the user-defined mode, other modes automatically select a more energy-efficient or comfortable airflow mode based on detection and judgment when the user's set requirements are met, achieving the dual goals of improving user comfort and energy savings.

[0070] Optionally, the air conditioner provided in this application is an up and down distributed air supply air conditioner.

[0071] Optionally, the air supply structure provided in the present application is applied to an indoor vertical cabinet air conditioner.

[0072] Air conditioning energy consumption is an important factor in my country's total energy consumption. In order to achieve the goal of "carbon neutrality", air conditioning energy saving is one of the important research directions; and as people's demand for indoor comfort becomes higher and higher, attention to the comfort of air supply of air conditioners has gradually become one of the important factors affecting market share. Taking all factors into consideration, it is necessary to take into account energy saving and comfort, reduce the proportion of energy dissipation of enclosing structures, and improve the energy utilization rate of human activity areas.

[0073] In recent years, major manufacturers have launched a new round of competition to improve air supply comfort, such as "distributed air supply" and "windless" solutions. "Windless" solutions often avoid the "cold draft" problem by sacrificing air volume and cooling capacity. "Distributed air supply" eliminates the "cold draft" problem by placing the upper air vents overhead, but it also creates a problem where the wind cannot be pushed downward, leading to low energy utilization in areas where people move. To provide a more comfortable, integrated indoor air supply scenario and reduce energy dissipation in the building envelope, it is necessary to target the thermal flow cycles of cooling and heating, ensuring that more cooling and heat are delivered to areas where people move, without blowing cold air on people. This achieves the dual goals of "comfort" and "energy conservation."

[0074] This application, incorporating the laws of thermal flow circulation, blows cool air upward, allowing it to naturally sink to areas where people are active; and compresses hot air downward, directly delivering heat to areas where people are active. This fundamentally resolves the compatibility issues of "cold air blowing on people" and "difficulty in suppressing air flow," achieving the dual goals of "preventing cold air from blowing on people" and "suppressing hot air," thereby reducing the proportion of energy dissipated by the enclosing structure and improving energy utilization in areas where people are active.

[0075] The present application provides an innovative curved airflow aggregation air supply technology and air supply structure, which can fundamentally solve the compatibility problem of "wind blowing on people" and "difficulty in pressing the wind", that is, taking into account the goals of "cold wind not blowing on people" and "pressing hot wind", thereby achieving the purpose of reducing the proportion of energy dissipation of the enclosing structure and improving the energy utilization rate of the human activity area.

[0076] In the preferred embodiment of the present application, based on the wall aggregation effect, the air supply scheme is combined with the curved air flow aggregation structure and the unique wind guide plate orientation design to achieve the dual goals of "no wind blowing on people" and "wind pressure". When the upward air supply state is adopted (such as cooling mode), the wind guide plate is tilted forward, and the wind is Figure 3 , the air is sent out through the air guide plate and the top curved surface, realizing the tilted upward air flow. When the downward pressure air supply state is adopted (such as heating mode), the air guide plate is tilted backward, and the air flow is tilted upward. Figure 4 , the airflow is gathered at the convex point of the rear curved surface through the air guide plate, and a high-pressure center is formed. After converging into a concentrated airflow, it is forced to turn and is guided through the top curved surface. The airflow is sent down along the top curved surface to achieve downward pressure on the airflow. In addition, the parameter design of the curved airflow aggregation air supply structure and its unique air guide plate orientation directly affect the effects of "the wind does not blow on people" and "pressed wind". When the parameter design relationship and spatial relationship of this application are met, the compatibility effects of "the wind does not blow on people" and "pressed wind" can be better met. By controlling the key parameters of the air supply structure, the aggregation point of the airflow can be accurately adjusted to achieve "directional and precise air supply", so that the air supply range of the air conditioner can reach -50°~30°, and the air supply distance can reach 9m, realizing all-round long-distance air supply indoors. In addition, the application also provides an air supply scene control method strategy for the air supply structure, which can realize multi-dimensional air supply regulation, meet the needs of different users and usage scenarios, and enhance the user's comfort experience and energy-saving experience "dual goals", see for details. Figures 5 and 6 .like Figure 5 As shown in the figure, when the temperature difference between the indoor temperature and the air conditioner set temperature is large, that is, ΔT1≥5℃, the air guide plate is in the 5th grid, which is the maximum pressure air mode, achieving a rapid cooling effect in the room. When the temperature difference between the indoor temperature and the air conditioner set temperature is relatively small, that is, ΔT1<5℃, the air guide plate is in the 2nd grid, and the cold air is sent upward to avoid being blown by the cold wind. Figure 6 As shown, the specific control method of the airflow at the heating outlet is: when the temperature difference between the air conditioner set temperature and the indoor temperature is large, that is, ΔT2 ≥ 5°C, the air guide plate is in the 5th grid, which is the maximum pressure wind mode, achieving a rapid heating effect in the room. When the temperature difference between the indoor temperature and the air conditioner set temperature is relatively small, that is, ΔT2 < 5°C, the air guide plate is in the 4th grid, and the hot air is collected and sent downward to improve human comfort. When cooling (heating), after control strategy regulation, it can meet the user's needs for "wind avoidance mode, rapid cooling, rapid heating, hot air collection and downward delivery, and user customization" and other modes. Among them, in addition to customization, other modes are detected and judged. When the user's set requirements are met, a more energy-saving or comfortable air outlet method will be automatically selected to achieve the "dual goals" of improving the user's comfort experience and energy-saving experience.

[0077] In summary, the present application can meet the multiple air supply goals under cooling, heating and other special usage requirements, can realize rapid temperature rise and fall, wind avoidance mode, "directional air supply" and air outlet modes that meet various air supply scenarios, increase the user's multiple selectivity and comfort, and improve the user's comprehensive usage scenario effect experience. It can also achieve the compatibility of the two contradictory two-way indicators of "wind not blowing people" and "pressured wind", and deliver more cold and heat to the human activity area, achieving the dual goals of "comfort" and "energy saving".
