Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an air guide plate movement mechanism, an upper air outlet structure, and an air conditioning unit. Background Technology

[0002] In existing air conditioning units with both top and bottom air outlets, the top air outlet has the following three air outlet methods:

[0003] The first type: The air outlet is located at the top of the cabinet air conditioner, with the air outlet facing upwards. The air outlet sweeps and guides the air through a guide vane structure. In this design, the sweeping angle is 90° < δ1 < 180° in the vertical plane. The airflow from the air outlet cannot blow downwards, which cannot meet the requirement of rapid cooling of the human body by blowing cold air downwards.

[0004] The second type: The air outlet is located at the top of the cabinet air conditioner, with the front of the air outlet facing forward. An air guide plate structure is set inside the air outlet to guide the air. In this solution, the air sweeping angle is 90°≤δ2<180° in the vertical plane, and the airflow from the top air outlet cannot blow downwards.

[0005] The third type: The top surface of the cabinet air conditioner is made into a slope, with the air outlet tilted upwards. The air guide plate is located outside the air outlet for guiding and sweeping the air. The sweeping angle of this design is 30° < δ3 < 180° in the vertical plane. This design has a large sweeping angle, and the upper air outlet can both compress and expel air, and also expel air upwards to avoid cold air blowing on people. However, the air guide plate is exposed in this design, which affects the appearance.

[0006] The applicant has discovered at least the following technical problems with the existing technology: In the above three solutions, the air outlet is guided or closed by an air guide plate. The air guide plate located inside the upper air outlet has a limited air guiding angle and cannot achieve downward airflow. The exposed air guide plate with a large air guiding angle affects the appearance of the air conditioner unit. In standby mode, small particles such as dust from the outside will accumulate on the outer surface of the air guide plate. When the air guide plate is opened, the small particles on the surface of the air guide plate will enter the air duct, which can easily contaminate the air conditioner. When the air conditioner is off, if an object is placed above the air outlet, the air guide plate will open after the air conditioner is turned on, and the object will fall into the air duct, which may damage the fan blades. Utility Model Content

[0053] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0056] This utility model provides a guide vane movement mechanism, an upper air outlet structure, and an air conditioning unit, which satisfies the function of the upper air outlet of the air conditioner blowing air downwards and realizes multi-angle air supply.

[0057] The following is combined with Figure 1-Figure 1 The technical solution provided by this utility model will be described in more detail.

[0058] Example 1:

[0059] See Figures 1-4 As shown, the air guide plate movement mechanism provided by this utility model includes an air guide plate 1, a first guide rail 21, a second guide rail 22, and a reversing mechanism located within the air outlet 200. The first guide rail 21 and the second guide rail 22 are connected and located on the side wall of the air outlet 200. The reversing mechanism is driven by the air guide plate 1 and is used to drive the air guide plate 1 to switch between the first guide rail 21 and the second guide rail 22. When the air guide plate 1 moves within the first guide rail 21, it can completely close or open the air outlet 200. When the air guide plate 1 moves within the second guide rail 22, it guides the airflow from the air outlet 200 downwards.

[0060] For details, see Figure 4 As shown, the second guide rail 22 is connected to the first guide rail 21 at the position facing the air outlet 200.

[0061] To ensure smooth movement, a slider is provided on the side of the air guide plate 1, and the slider is slidably connected to the first guide rail 21 or the second guide rail 22.

[0062] The air guide plate movement mechanism provided in this embodiment is located inside the air outlet 200, and its structure is not exposed to prevent interference between the air guide plate movement mechanism and external objects. When the air guide plate 1 moves within the first guide rail 21, it can completely close or open the air outlet 200 and achieve horizontal airflow. When the air conditioner is in standby mode, the air guide plate 1 completely closes the air outlet 200, isolating the air duct of the air conditioner from the outside and preventing external objects from entering the air conditioner. When the reversing mechanism drives the air guide plate 1 into the second guide rail 22, the air guide plate 1 moves within the second guide rail 22, which can guide the airflow of the air outlet 200 downward, satisfying the function of the air outlet 200 of the air conditioner blowing downward and realizing multi-angle air supply.

[0063] As an optional implementation, see Figure 3 and Figure 4 As shown, the first guide rail 21 is vertically arranged, one end of the second guide rail 22 is connected to the first guide rail 21, and the other end of the second guide rail 22 is offset from bottom to top towards the air duct. The second guide rail 22 is an arc-shaped guide rail or a straight guide rail.

[0064] The air guide plate movement mechanism in this embodiment also includes a drive mechanism, which is used to drive the air guide plate 1 to move along the first guide rail 21 or the second guide rail 22.

[0065] With this configuration, when the air guide plate 1 is located within the first guide rail 21, the drive mechanism drives the air guide plate 1 to move vertically, thereby fully opening, fully closing, or partially opening the air outlet 200. Figure 1 and Figure 2 As shown. When the air guide plate 1 is located inside the second guide rail 22, the drive mechanism drives the air guide plate 1 to move along the second guide rail 22. When the air guide plate 1 moves to the upper limit position of the second guide rail 22, it is used to guide the airflow downward out of the air outlet 200.

[0066] As an optional implementation, see Figure 3 and Figure 4 As shown, the second guide rail 22 is an arc-shaped guide rail. When the air guide plate 1 is inside the second guide rail 22, the air guide plate 1 is an arc-shaped plate that matches the second guide rail 22, and the outer surface of the air guide plate 1 forms a downward air pressure arc surface 101. The first guide rail 21 is a straight guide rail. When the air guide plate 1 is inside the first guide rail 21, the air guide plate 1 is a straight plate that matches the first guide rail 21.

[0067] Specifically, the air guide plate 1 is a flexible structure that can deform when moving along the second guide rail 22, presenting an arc-shaped plate structure. When the air guide plate 1 moves along the first guide rail 21, the air guide plate 1 presents a straight plate shape.

[0068] Specifically, the air guide plate 1 is injection molded from soft rubber. Slider blocks are provided on both sides of the air guide plate 1. The sliders are embedded in the first guide rail 21 or the second guide rail 22 and move along the corresponding trajectory, thereby realizing the closing of the air guide plate 1 and the function of guiding and compressing air.

[0069] See Figure 11 As shown, when the air guide plate 1 moves to the upper limit position of the second guide rail 22, the outer surface of the air guide plate 1 forms a downward air pressure arc surface 101, which is used to guide the airflow downward out of the air outlet 200.

[0070] This embodiment provides a specific implementation of a reversing mechanism; see [link to details]. Figures 5-10 , Figure 13 As shown, the reversing mechanism in this embodiment includes a reversing drive device and a reversing gear 32, wherein the reversing gear 32 is fixedly connected to the air guide plate 1. (See attached image) Figure 13 As shown, the reversing gear 32 is provided with a first through groove 321 and a second through groove 322; the reversing drive device is driven to connect with the reversing gear 32 and is used to drive the reversing gear 32 to rotate; the reversing gear 32 can rotate to the position where the first through groove 321 is connected to the first guide rail 21, thereby switching the air guide plate 1 to the first guide rail 21, see [reference]. Figure 11 and Figure 12 As shown, the reversing gear 32 can rotate to the position where the second through slot 322 is connected to the second guide rail 22, thereby switching the air guide plate 1 to the second guide rail 22.

[0071] The aforementioned reversing drive device is a drive motor. A drive gear 31 is installed at the output end of the reversing drive device. The drive gear 31 meshes with a reversing gear 32. The reversing drive device drives the reversing gear 32 to rotate. Since the reversing gear 32 is fixedly connected to the air guide plate 1, the air guide plate 1 rotates. When the second through slot 322 is connected to the second guide rail 22, the air guide plate 1 moves along the second guide rail 22 until it reaches the upper limit position of the second guide rail 22. The downward pressure arc surface 101 of the air guide plate 1 guides the airflow downwards. When the air guide plate 1 rotates until the first through slot 321 is connected to the first guide rail 21, the air guide plate 1 moves along the first guide rail 21 under the drive of the drive mechanism. The vertical lifting and lowering of the air guide plate 1 can fully or partially open the air outlet 200, or fully close the air outlet 200, to achieve horizontal airflow.

[0072] As an optional implementation, see Figure 13 As shown, the first through groove 321 and the second through groove 322 both penetrate the corresponding outer edge of the reversing gear 32. The shape of the first through groove 321 matches the shape of the first guide rail 21, and the shape of the second through groove 322 matches the shape of the second guide rail 22.

[0073] With this setting, such as Figure 12As shown, when the first through slot 321 is connected to the first guide rail 21, the two work together to limit the movement of the air guide plate 1 along the first guide rail 21 under the drive of the drive mechanism; when the second through slot 322 is connected to the second guide rail 22, the two work together to limit the movement of the air guide plate 1 along the second guide rail 22 under the drive of the drive mechanism.

[0074] As an optional implementation, see Figure 12 As shown, the air guide plate movement mechanism also includes a baffle 4, which is rotatably configured. The baffle 4 can abut against the air guide plate 1 in the second guide rail 22 and form a downward air pressure structure. The downward air pressure structure guides the air in the air duct to the air outlet 200 and blows the air downward along the outer surface of the air guide plate 1.

[0075] See Figure 12 As shown, in this embodiment, when the air guide plate 1 moves along the second guide rail 22 to the upper limit position, the baffle 4 is in a vertical state. At this time, the baffle 4 guides the air duct vertically upward. After the air reaches the air outlet 200, it is blown downward under the guidance of the downward pressure air arc surface 101 of the air guide plate 1, so as to realize multi-angle air supply.

[0076] Correspondingly, when the baffle 4 is located within the first guide rail 21, the baffle 4 is in a horizontal state to prevent the baffle 4 from affecting the airflow from the air outlet 200.

[0077] This embodiment provides a specific implementation of a reversing mechanism that simultaneously enables the rotation of the air guide plate 1 and the baffle 4.

[0078] See Figures 5-10 , Figure 13 As shown, the reversing mechanism includes a reversing drive device, a driven gear 33, and a reversing gear 32. Specifically, the output end of the reversing drive device is connected to the driven gear 33 and the reversing gear 32. The output end of the reversing drive device is fixed with a drive gear 31, which meshes with both the driven gear 33 and the reversing gear 32. The reversing gear 32 is fixedly connected to the air guide plate 1, and the driven gear 33 is fixedly connected to the baffle 4. The reversing drive device can drive the driven gear 33 and the reversing gear 32 to rotate simultaneously. When the air guide plate 1 moves to the upper limit position within the second guide rail 22, the baffle 4 is in a vertical state, and the upper end of the baffle 4 abuts against the upper end of the air guide plate 1, thereby forming a downward pressure air structure.

[0079] The reversing gear 32 is provided with a first through groove 321 and a second through groove 322; the reversing gear 32 can rotate to the position where the first through groove 321 is in communication with the first guide rail 21, thereby switching the air guide plate 1 to the first guide rail 21, see [reference]. Figure 11 and Figure 12As shown, the reversing gear 32 can rotate to the position where the second through slot 322 is connected to the second guide rail 22, thereby switching the air guide plate 1 to the second guide rail 22.

[0080] For the reversing mechanism in this embodiment, see [link / reference]. Figures 5-10 As shown, the reversing drive device can simultaneously drive the driven gear 33 and the reversing gear 32 to rotate. That is, when the reversing drive device is activated, it can realize the simultaneous rotation of the baffle 4 and the air guide plate 1. When the air guide plate 1 moves to the upper limit position of the second guide rail 22, the baffle 4 is in a vertical state, and the upper end of the baffle 4 abuts against the upper end of the air guide plate 1, thereby forming a downward air pressure structure, thus realizing multi-angle air delivery.

[0081] Specifically, guided by the downward pressure structure, the sweeping angle of the air guide plate 1 increases from [90°, 180°] to (30°, 180°) to meet different usage requirements. The downward pressure effect of the air guide plate 1 is as follows: Figure 11 As shown.

[0082] As an optional implementation, see Figure 11 and Figure 14 As shown, the air guide plate movement mechanism also includes a drive mechanism. The drive mechanism includes a housing 51, a moving drive device 52 located inside the housing 51, a rack 53, and a connecting rod 54. The housing 51 and the rack 53 are both vertically arranged. The output end of the moving drive device 52 is connected to the rack 53 for transmission. The two ends of the connecting rod 54 are rotatably connected to the rack 53 and the air guide plate 1, respectively. The drive mechanism is used to drive the air guide plate 1 to move along the first guide rail 21 or the second guide rail 22.

[0083] In this embodiment, the mobile drive device 52 can be a motor. A gear is fixed to the output end of the mobile drive device 52, and the gear meshes with the rack on the rack rod 53, thereby achieving vertical movement of the rack rod 53. When the air guide plate 1 is located within the first guide rail 21, the air guide plate 1 moves vertically; when the air guide plate 1 is located within the second guide rail 22, the air guide plate 1 moves along the second guide rail 22. Figure 11 As shown.

[0084] Among them, the connecting rod 54 movably connects the rack rod 53 and the air guide plate 1, which plays a role in motion buffering and changing the direction of force.

[0085] As an optional implementation, the travel stroke S of the rack 53 and the travel stroke S1 of the air guide plate 1 on the second guide rail 22 must satisfy: S1≤S≤L, where L is the width of the air outlet 200.

[0086] The rotation angle of the reversing gear 32 controls the function of the air guide plate 1. The reversing wheel and the straight track are set as the origin. When the air guide plate 1 needs to perform the air compression function, the reversing gear 32 rotates by an angle α1. The second through groove 322 on the reversing gear 32 connects to the second track. The air guide plate 1 slides along the second track, and the corresponding baffle 4 rotates by an angle α2, forming a downward air compression structure with the air guide plate 1.

[0087] As an optional implementation, in order to satisfy the closing and air guiding functions of the air guide plate 1, the length H and width B2 of the air guide plate 1 must satisfy: H = L + C, B2 = B1 + 2m - 2γ; where L is the height of the air outlet 200, B1 is the width of the air outlet 200, C is the length of the connection section between the air guide plate 1 and the drive mechanism, m is the depth of the first guide rail 21 and the second guide rail 22, and γ is the assembly gap value between the air guide plate 1 and the first guide rail 21, or between the air guide plate 1 and the second guide rail 22.

[0088] Example 2:

[0089] This embodiment provides an upper air outlet structure, including the above-mentioned air guide plate movement mechanism, and the air outlet 200 is an upper air outlet 200.

[0090] For the 100-type floor-standing air conditioner, the upper air outlet 200 should be as large as possible in height and width to achieve a larger air volume and reduce wind resistance. However, considering the appearance and structural layout, the size of the upper air outlet 200 should not be too large, as an excessively large outlet 200 will result in a poor appearance.

[0091] In this embodiment, see Figure 1 As shown, the width B1 of the upper air outlet 200 and the width A of the cabinet unit 100 must satisfy: B1≤A-2n, where n is the distance between the side edge of the upper air outlet 200 and the side wall of the cabinet unit 100.

[0092] The height dimension L of the upper air outlet 200 can have a wider range than the height dimension. To ensure the aesthetic appearance, the height dimension L and the width dimension B1 of the upper air outlet 200 are generally designed according to the golden ratio: L / B1≈0.618 or B1 / L≈0.618, and L is generally between 250 and 150 mm.

[0093] Example 3:

[0094] This embodiment provides an air conditioner cabinet unit 100, including the above-described top air outlet structure.

[0095] The air conditioner unit 100 in this embodiment has the following operating modes:

[0096] 1. Standby state: When the air conditioner is in standby state, the control module controls the drive mechanism to return to the origin position. At this time, the rack rod 53 is in the upper working position and the air guide plate 1 is in the closed state.

[0097] 2. Flat air blowing mode: When the air conditioner is started, the drive mechanism rotates, and the rack and pinion 53 drives the air guide plate 1 to move downward by L strokes. The air guide plate 1 is in the lower limit working position, and the upper air outlet 200 is in a fully open state. The air guide plate 1 inside the air duct is opened at the maximum angle. At this time, the airflow from the upper air outlet 200 blows straight out to the outside, with a long air delivery distance.

[0098] 3. Top air outlet mode: When the air conditioner is switched to top air outlet mode, the air guide plate 1 is in the lower limit working position, the top air outlet 200 is in a fully open state, the air guide plate 1 is opened at an angle β, at this time the airflow of the top air outlet 200 blows upward through the air guide plate 1 to avoid cold air blowing on people.

[0099] 4. Downward Air Outlet Mode: When the air conditioner switches to downward air outlet mode, the air guide plate 1 moves to the lower working limit. The reversing drive device causes the drive gear 31 to rotate by angle α0, the reversing gear 32 to rotate by angle α1, and the baffle 4 to rotate by angle α2, switching to the second track. Afterward, the drive mechanism drives the air guide plate 1 to move upward along the second track. The air guide plate 1 inside the air duct opens to its maximum angle, and the airflow from the upper air outlet 200 blows downward along the air guide plate 1, achieving a compressed air outlet effect.
