Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and particularly relates to a guide grille structure and an air conditioner. Background Art

[0002] When the current air conditioner operates in the super-low temperature environment outdoors, even if it operates at the lower limit speed of 20% of the rated speed of the commonly used fan in the market, it will cause the condensation temperature and pressure on the high-pressure side of the air conditioner to be too low. After throttling, the refrigerant pressure is even lower, and the refrigerant temperature is even lower than 0°C, resulting in easy frosting and icing of the evaporator, reducing the heat exchange area, further intensifying the frosting situation and entering a vicious cycle until the refrigerant cannot be completely evaporated into a gaseous state in the evaporator, causing liquid carry-back in the compressor return air. In severe cases, it may even cause damage to the compressor due to liquid hammer. In addition, the frosting of the evaporator will also cause problems such as attenuation of refrigeration capacity and potential leakage inside, affecting the reliability of the air conditioner.

[0003] In summary, it is necessary to absolutely avoid excessive condensation of the refrigerant in the condenser in the super-low temperature environment. However, it is difficult for the existing fan technology to achieve stepless speed regulation in the range of 0%-20%. There are problems such as difficult debugging in controlling the condensation temperature within a reasonable range through the strategy of starting and stopping the fan, potential reliability hazards due to refrigerant fluctuations, and reduced fan life.

Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0029] As Figure 4 and 6 shown, the present utility model first provides an air guiding grille structure 93. The air guiding grille structure 93 includes a frame 1. The frame 1 is square. The frame 1 includes a frame body 11 and frame columns 12 located at both ends of the frame body 11. The frame columns 12 include a first frame column 121 and a second frame column 122. The frame body 11 and the frame columns 12 have cavities.

[0030] As Figure 4 and Figure 5 shown, the air guiding grille structure 93 includes a plurality of blades 3. The blades 3 are arranged in the cavity of the frame body 11. The plurality of blades 3 are parallel to each other. The two ends of the blades 3 can be rotationally adjusted at the cooperation positions with the frame 1. The plurality of blades 3 are horizontally arranged in parallel. The adjustment angle θ ranges from horizontal to obliquely upward to 90° of completely vertical closure.

[0031] As Figure 4 and Figure 6As shown, the air guide grille structure 93 includes a first connecting rod 41. One end of the first connecting rod 41 is connected to one end of the swing blade 3, and the other end of the first connecting rod 41 is located in the cavity of the first frame column 121.

[0032] As Figure 3 and Figure 4 As shown, the air guide grille structure 93 includes a power assembly. The power assembly is arranged in the cavity of the first frame column 121. The power assembly includes a screw rod 5. One end of the screw rod 5 is connected to a motor 51. The motor 51 is a stepper motor. The other end of the screw rod 5 is connected to a limit block 52. One ends of the motor 51 and the limit block 52 are both fixed on the inner wall of the cavity of the first frame column 121. A slider 53 is also sleeved on the screw rod 5.

One end of the crank 7 is rotatably connected to the connecting rod 6, and the other end of the crank 7 is connected to the other end of the first connecting rod 41. The connecting rod 6 and the crank 7 are used to drive a plurality of the swing blades 3 to rotate synchronously and parallelly to adjust the air flow area of the air guide grille structure 93.

[0035] As Figure 2 and Figure 6 As shown, the air guide grille structure 93 includes a second connecting rod 42. One end of the second connecting rod 42 is connected to the other end of the swing blade 3, and the other end of the second connecting rod 42 is located in the cavity of the second frame column 122.

[0036] As Figure 3 and Figure 4As shown, the slider 53 includes a slider body 531 and a sliding piece 532 fixedly connected to the slider body 531. A notch 621 is formed on the sliding rod 62, and the sliding piece 532 is inserted into the notch 621. The slider 53 converts the change in the stroke position into the change in the rotation angle of the crank 7 through the sliding rod 62, thereby driving the swing blade 3 to synchronously adjust the rotation opening degree.

[0037] As Figure 1 shown, the present invention further provides an air conditioner, which includes the air guide grille structure 93 as described above.

[0038] As Figure 1 shown, the air conditioner includes an air conditioner housing 8. The frame 1 of the air guide grille structure 93 can be fixedly connected to the air conditioner housing 8, such as snap connection, riveting, screw connection, etc. The riveting can play an anti-theft role. An accommodation cavity is provided inside the air conditioner housing 8, and the air guide grille structure 93 is fixedly connected inside the accommodation cavity.

[0039] As Figure 1 shown, the air conditioner includes an outer air outlet 82, and the outer air outlet 82 is formed on one side of the air conditioner housing 8.

[0040] As Figure 1 shown, the air conditioner includes an outer circulation air duct 9, and the outer circulation air duct 9 is arranged inside the accommodation cavity. The air guide grille structure 93 is arranged in the outer circulation air duct 9 of the air conditioner and is matched with the structure of the outer circulation air duct 9.

[0041] As Figure 1 shown, the air conditioner includes a condenser 92, and the condenser 92 is located inside the accommodation cavity. The air guide grille structure 93 is arranged on one side of the condenser 92, and the air guide grille structure 93 is located between the outer air outlet 82 and the condenser 92.

[0042] As Figure 1 shown, the air conditioner includes an outer side blower 91, and the outer side blower 91 is arranged inside the accommodation cavity and is located below the condenser 92.

[0043] As Figure 1 shown, the air conditioner includes an outer air inlet 81, and the outer air inlet 81 is arranged on the air conditioner housing 8 and is located on one side of the outer side blower 91.

[0044] As Figure 1 shown, the air conditioner includes a middle partition 11, and the middle partition 11 is located inside the accommodation cavity and is arranged on the other side of the condenser 92. The middle partition 11 divides the accommodation cavity into an inner circulation air duct 10 and the outer circulation air duct 9.

[0045] As Figure 1 shown, the guide grille structure 93 is arranged between the condenser 92 and the outer air outlet 82, and controls the heat dissipation air volume of the condenser 92 by adjusting the air flow cross-sectional area. When the air-cooled energy storage air conditioner is refrigerating, the hot air dissipated by the condenser 92 can be blown obliquely upward, which conforms to the hydrodynamic design of hot air rising. To a certain extent, it avoids the hot air blown by the condenser 92 from being easily sucked in by the outer air inlet 81 and causing air return short circuit, thus playing a role in optimizing the outer circulation air duct 9.

[0046] Principle of the present utility model:

[0047] Start the motor 51 on the frame 1, drive the slider 53 screwed to the screw rod 5 to move up and down through the motor output shaft. The slide piece 532 fixed on the body of the slider 53 is located in the notch 621 opened on the slide rod 62, and then drives the connecting rod 6 to move up and down. The limit block 52 limits the maximum stroke of the movement of the slider 53. The slider 53 converts the change of the stroke position into the change of the rotation angle of the crank 7 through the slide rod 62, and then drives the swing blade 3 to synchronously adjust the rotation opening. The adjustment angle θ is 90° from horizontal to obliquely upward to completely vertically closed. Adjusting the angle θ of the swing blade 3 can control the air flow cross-sectional area. Further, in the small air volume adjustment dead zone where the outer fan 91 cannot complete the adjustment by itself, the air volume is adjusted. By adjusting the air flow cross-sectional area, the heat dissipation air volume of the condenser 92 is controlled. When the air-cooled energy storage air conditioner is refrigerating, the hot air dissipated by the condenser 92 can be blown obliquely upward, which conforms to the hydrodynamic design of hot air rising. To a certain extent, it avoids the hot air blown by the condenser 92 from being easily sucked in by the outer air inlet 81 and causing air return short circuit, thus playing a role in optimizing the outer circulation air duct 9.
