Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air guide plate assembly, an air conditioner provided with the air guide plate assembly, and an air outlet method. Background Art

[0002] In real life, when people start using air conditioners, they hope to achieve rapid cooling and obvious blowing effects. After using it for a period of time, as the temperature in the room drops rapidly, the high wind speed and direct blowing of the air conditioner will cause discomfort to the human body. In order to solve the comfort problem, a sweeping structure is provided in the air conditioner. In the traditional sweeping structure design, indoor wall-mounted air conditioners generally use wind guide plates and wind sweeping blades to achieve wind sweeping and drainage to achieve the purpose of left and right wind sweeping and up and down wind sweeping. Using this method for sweeping air, on the one hand, cannot meet the different cooling needs of users at different times. On the other hand, the wind guide plate is generally a straight plate with a certain curvature, and the wind guide direction is relatively fixed, with poor flexibility.

[0003] In addition, in the general air conditioner structure, since the air guide plate has a certain thickness, under cooling conditions, when the air conditioner is running, cold air reaches the top of the air guide plate through the air outlet. At this time, the bottom of the air guide plate is still the original hot air in the room. The temperature difference between the cold and hot is large, and condensation is easily formed on the air guide plate. Summary of the invention

[0027] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0028] See also Figure 1-Figure 4 The present invention provides an air guide assembly, including a spoiler structure 1 and an air guide plate, wherein the spoiler structure 1 and the air guide plate are both rotatably connected to the air conditioner housing 2, and when the spoiler structure 1 and the air guide plate open the air outlet of the air conditioner, the spoiler structure 1 is rotated to the air outlet so that the air discharged by the air conditioner can be discharged through the spoiler pores on the spoiler structure 1. When the air conditioner is turned on, the air guide assembly is rotated out, and within a period of time, the air flow is directly blown out through the air outlet, the air volume is large, the wind feeling is strong, and a rapid cooling effect can be achieved, bringing an intuitive blowing feeling. When the room temperature drops, a strong wind feeling is not needed, and the spoiler structure 1 or the spoiler structure 1 and the air guide plate can be adjusted so that the air discharged by the air conditioner can be discharged through the spoiler pores on the spoiler structure 1. At this time, the air flow boundary layer is destroyed, the air flow form becomes a turbulent flow, the cold air flow distribution is more uniform, the air conditioner no longer has a strong blowing wind feeling, and a better room comfort effect is achieved.

[0029] As an optional implementation of the embodiment of the present invention, the air guide plate includes an upper air guide plate 3 and a lower air guide plate 4 arranged at the lower side of the upper air guide plate 3. The upper air guide plate 3 and the lower air guide plate 4 are both rotatably connected to the air conditioner housing 2. When the air guide plate closes the air outlet, a hollow cavity structure is formed inside the upper air guide plate 3 and the lower air guide plate 4, and the spoiler structure 1 is located in the hollow cavity structure. Figure 1 and Figure 2 , showing the upper air guide plate 3 and the lower air guide plate 4, see Figure 1 , showing that the air guide plate assembly closes the air outlet of the air conditioner, at this time, the spoiler structure 1 is located in the hollow cavity structure formed by the upper air guide plate 3 and the lower air guide plate 4; see Figure 2, the air guide assembly is opened, the upper air guide plate 3, the lower air guide plate 4 and the spoiler structure 1 are turned to the open position together, at this time, the spoiler structure 1 is still located in the hollow cavity structure formed by the upper air guide plate 3 and the lower air guide plate 4, and the air flow is directly blown out through the air outlet, the air volume is large, the wind feeling is strong, and a rapid cooling effect can be achieved; see Figure 3 , indicating the location of the spoiler structure 1 at the air outlet. Figure 2 Convert to Figure 3 In the position shown, the lower air guide plate 4 can remain in place, the upper air guide plate 3 rotates into the air conditioner housing 2, and the spoiler structure 1 moves to the air outlet, so that the air exhausted by the air conditioner can be discharged through the spoiler pores on the spoiler structure 1, and the cold air flow distribution is more uniform. The air conditioner no longer has a strong blowing wind feeling, and a better room comfort effect is achieved. Regarding the rotation of the upper air guide plate 3, the lower air guide plate 4 and the spoiler structure 1, different drive motors can be used to drive the three to rotate relative to the air conditioner housing 2. In addition, since a hollow cavity structure is formed inside the upper air guide plate 3 and the lower air guide plate 4, when the air conditioner blows air, the formation of condensation can be effectively prevented.

[0030] Of course, regarding the structure of the air guide plate, the upper air guide plate 3 may not be included, that is, the air guide plate assembly only includes the lower air guide plate 4 and the spoiler structure 1, thereby simplifying the structure of the air guide plate assembly.

[0031] As an optional implementation method of the embodiment of the present invention, the upper air guide plate 3 and the lower air guide plate 4 are both thin plates, the lower air guide plate 4 is an arc-shaped plate and the curvature of the lower air guide plate 4 is greater than that of the upper air guide plate 3, so that the upper air guide plate 3 can be easily retracted into the air conditioner during operation.

[0032] As an optional implementation scheme of an embodiment of the present invention, the spoiler structure 1 is a plate-like structure, that is, the spoiler structure 1 can be a plate-like structure with distributed flow-guiding micropores (spoiler pores); or, the spoiler structure 1 is formed by assembling connecting rods, that is, adjacent connecting rods are arranged at intervals to form spoiler pores.

[0033] The specific structure of the spoiler structure 1 can be as follows: Figure 3 The spoiler structure 1 includes a spoiler rod 5, which extends along the length direction of the air outlet. A plurality of spoiler rods 5 are arranged in parallel and spaced apart in sequence. The same end of all spoiler rods 5 is connected by a corresponding fixing rod structure, and the fixing rod structure is connected to the air conditioner housing 2 or the air guide plate. Figure 3 , showing that the spoiler structure 1 is located at the air outlet, the air flow in the air conditioner can be discharged through the gap between two adjacent spoiler rods 5. Of course, see Figure 3, above the top spoiler rod 5 and below the bottom spoiler rod 5, there will also be airflow passing. After the airflow flows through the spoiler structure 1, the airflow boundary layer is destroyed, effectively realizing the transformation of the airflow from laminar flow to turbulent flow. In the wake area, the airflow forms multiple vortex streets, which directly affect each other, achieving better airflow exchange, thereby forming a soft wind effect. Of course, the distribution of the spoiler rods 5 is not limited to the above structure. The spoiler rods 5 can be arranged vertically at intervals in sequence, and the spoiler rods 5 can be arc-shaped curved rods, etc. As long as the spoiler structure with "spoiler pores" is assembled by connecting rods, it is within the protection scope of the present invention. The fixed rod structure can be rotatably connected to the air conditioner housing 2, or rotatably connected to the upper air guide plate 3.

[0034] The cross-sectional shape of the spoiler rod 5 is circular, elliptical or polygonal. That is, the cross-sectional shape of the spoiler rod 5 is not limited too much, but is preferably circular.

[0035] When the cross-sectional shape of the spoiler rod 5 is circular, the diameter of the spoiler rod 5 ranges from 2.5 mm to 3.5 mm, preferably 3 mm; the ratio of the distance between the central axes of two adjacent spoiler rods 5 to the diameter of the spoiler rod 5 is not greater than 4. That is, the distance between two adjacent spoiler rods 5 can be reasonably set according to the number of spoiler rods 5 and the diameter of the spoiler rods 5. Figure 3 , indicating that the spoiler structure 1 includes five spoiler rods 5. Of course, the number of spoiler structures 1 is not limited to five, and can also be other reasonable number values. The five spoiler rods 5 can be arranged in an arc shape, and the arc radius ranges from 28mm to 33mm, preferably 31.857mm.

[0036] As an optional implementation of the embodiment of the present invention, the end of the spoiler rod 5 is inserted into the corresponding fixed rod structure and a bearing is provided between the spoiler rod 5 and the fixed rod structure. The fixed rod structure can be an integrated structure, and there is a convex portion at the end of the spoiler rod 5, and the convex portion of the spoiler rod 5 is inserted into the connecting bearing, and the connecting bearing is assembled on the fixed rod structure.

[0037] An air conditioner includes the air guide plate assembly of the present invention. The air conditioner is preferably a wall-mounted unit. When the room temperature is high and the air conditioner is just turned on, the air guide plate assembly is opened, and the air flow is blown out directly through the air outlet, so that the room temperature drops rapidly; after a certain period of time, when the room temperature drops to the required temperature, the spoiler structure 1 or the spoiler structure 1 and the air guide plate are adjusted so that the air discharged from the air conditioner can be discharged through the spoiler pores on the spoiler structure 1, so as to realize time-divided air supply.

[0038] A method for adjusting the air outlet of an air conditioner by using an air guide plate assembly includes the following contents: starting the air conditioner, when the indoor temperature does not reach a preset temperature range, the spoiler structure 1 and the air guide plate open the air outlet of the air conditioner, and the air flow is blown out directly through the air outlet, with a large air volume and a strong wind feeling, which can achieve a rapid cooling effect and bring an intuitive blowing feeling; when the indoor temperature reaches a preset temperature range, the spoiler structure 1 is actuated or the spoiler structure 1 and the air guide plate are actuated together to allow the air discharged from the air conditioner to be discharged through the spoiler pores on the spoiler structure 1. At this time, the airflow boundary layer is destroyed, the airflow flow form becomes a turbulent flow, the cold air flow distribution is more uniform, the air conditioner no longer has a strong blowing wind feeling, and a better room comfort effect is achieved.

[0039] When the air guide plate includes an upper air guide plate 3 and a lower air guide plate 4, a hollow cavity structure is formed inside the upper air guide plate 3 and the lower air guide plate 4, and the spoiler structure 1 is located in the hollow cavity structure, regarding the spoiler structure 1 and the air guide plate to open the air outlet of the air conditioner: the upper air guide plate 3, the lower air guide plate 4 and the spoiler structure 1 rotate together in the same direction to open the air outlet; and when the upper air guide plate 3 rotates into the air conditioner housing 2, the spoiler structure 1 moves to the air outlet, so that the air discharged from the air conditioner can be discharged through the spoiler pores on the spoiler structure 1. Specifically, when the air conditioner is not in operation, refer to Figure 1 , the air guide plate assembly is in a closed state, intersecting with the air conditioner housing 2 to form a closed shell. When the air conditioner starts to operate, the air guide plate assembly is rotated out of an angle of α by the motor. Within a period of time, the air flow is blown out directly through the air guide plate, with a large air volume and a strong wind feeling, which can achieve a rapid cooling effect and bring an intuitive blowing experience. Due to the special structure of the air guide plate, condensation can be prevented. When the room temperature drops, the upper air guide plate 3 rotates upward at an angle of β, hidden in the air conditioner, and the spoiler structure 1 rotates, and the angle between the spoiler structure 1 and the upper air guide plate 3 is γ degrees. Among them, the value range of α is 50 degrees to 60 degrees, preferably 55 degrees; the range of the upper air guide plate 3 rotating upward at an angle of β is 154 degrees to 156 degrees, preferably 155 degrees; the angle between the free terminal of the spoiler structure 1 and the upper air guide plate 3 is γ degrees, and the value range of γ is 85 degrees to 95 degrees, preferably 90 degrees.

[0040] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
