Abstract
Description
Technical Field
[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to an air conditioner. Background Technology
[0002] The air outlet design of current cross-flow air conditioners uses a door opening and closing mechanism plus an air deflector. The air deflector is driven by one mechanism, while the door opening and closing requires another. In operation, the door must be opened using one mechanism, and then the air deflector must be opened using another mechanism to allow airflow to be delivered to the outside. Therefore, the air outlet structure of commonly used cross-flow air conditioners is complex, and both the door opening and closing mechanism and the air deflector require independent driving mechanisms, resulting in higher costs. Furthermore, cross-flow air conditioners on the market have a single air outlet duct, and their air outlet angle is relatively small.
[0003] Therefore, this application designs an air conditioner that does not require opening and closing the door, thereby reducing one set of drive mechanism and door opening and closing, simplifying the structure of the air conditioner, and reducing the cost of the air conditioner; in addition, this application has a single cross-flow dual air outlet channel, with a larger air outlet angle.

[0009] In one embodiment, the included angle between the two branch ducts is in the range of 90°-130°.
[0010] In one embodiment, the inner wall of the diversion duct has a step, and when the windproof assembly closes the diversion duct, the windproof plate is placed on the step.
[0011] In one embodiment, the housing has a volute tongue and a volute plate, wherein one of the diversion ducts is located in the extension direction of the volute tongue.

[0031] Currently, single-flow air conditioners on the market use a door outside the air guide plate for air outlet. Both the air guide plate and the door require a matching drive mechanism. During use, the door must be opened before the air guide plate can be opened. This type of air conditioner has a complex structure and a relatively small air outlet angle. Therefore, this application designs an air conditioner that eliminates the need for a door, reducing one drive mechanism and door, simplifying the air conditioner's structure, and lowering its cost. Furthermore, this application features a single-flow dual-air outlet channel, resulting in a wider air outlet angle.
[0032] Please refer to Figure 1 , Figure 2 and Figure 3 As shown, one embodiment of this application provides an air conditioner 100, including a housing 10, a fan 20, and a wind deflector assembly 30. The fan 20 is disposed inside the housing 10, and the wind deflector assembly 30 is rotatably disposed on the housing 10. The housing 10 forms two interconnected branch air ducts 11 and a main air duct 12 inside it, with the starting position of the main air duct 12 facing the fan 20. The wind deflector assembly includes a first wind deflector assembly 30a and a second wind deflector assembly 30b, which are respectively disposed at the ends of the two branch air ducts 11 to open and close the branch air ducts 11. When the wind deflector assembly 30 opens the branch air ducts 11, the air at the fan 20 can be sent out to the outside through the branch air ducts 11; when the wind deflector assembly 30 closes the branch air ducts 11, the air at the fan 20 cannot be sent out through the branch air ducts 11.
[0033] Specifically, the air conditioner 100 of this application includes a housing 10, a fan wheel 20, a first wind deflector assembly 30a, and a second wind deflector assembly 30b. The fan wheel 20 is disposed inside the housing 10. A main air duct 12 and two branch air ducts 11 are formed inside the housing 10. The starting position of the main air duct 12 is positioned towards the fan wheel 20 to guide the airflow from the fan wheel 20 to the two branch air ducts 11. The two branch air ducts 11 are respectively connected to the main air duct 12 and extend outward from the housing 10. The first wind deflector assembly 30a is disposed at the end of one of the branch air ducts 11, and the second wind deflector assembly 30b is disposed at the end of the other branch air duct 11. The wind deflector assembly 30 controls the opening and closing of the branch air ducts 11 to control the airflow. The wind deflector assembly 30 is rotatably disposed at the end position of the branch air duct 11, and the rotation of the wind deflector assembly 30 opens and closes the branch air duct 11. The single-flow air conditioner 100 of this application employs a single impeller 20 and forms a dual-outlet structure through a main air duct 12 and two branch air ducts 11. The dual outlets allow for a wider air outlet angle, improving the cooling or heating speed; the cooling or heating is also more uniform indoors, enhancing user comfort. Furthermore, the air outlet structure of this application, using only a baffle assembly, can replace the air deflector and door-type air outlet structures found in the market; compared to this solution, this application eliminates the need for a door. Commercial air conditioners have a door outside the air deflector, and both the door and the air deflector require independent drive structures, making the structure complex. This application also reduces the drive structure for the door, thus reducing the cost of raw materials for this component.
[0034] Please refer to Figure 3 , Figure 5 and Figure 7 As shown, in an optional embodiment, both the first wind deflector assembly 30a and the second wind deflector assembly 30b include at least two wind deflector plates 31 and a plurality of connecting rods 32. The connecting rods 32 are used to drive all the wind deflector plates 31, and the wind deflector plates 31 are rotatably disposed within the housing 10.
[0035] Specifically, in this embodiment, the first windbreak assembly 30a and the second windbreak assembly 30b have the same structure, both including two windbreak plates 31 and two connecting rods 32 spaced apart on the two windbreak plates 31. The two connecting rods 32 are respectively located at both ends of the length direction of the two windbreak plates 31, and the two windbreak plates 31 are connected by the connecting rods 32 so that the two windbreak plates 31 can rotate synchronously. The two windbreak plates 31 are laid flat and block the outlet of the diversion duct 11 to close the diversion duct 11. During the rotation of the two windbreak plates 31, the outlet of the diversion duct 11 will gradually open, at which time airflow can be delivered to the outside.
[0036] like Figure 7As shown, the wind deflector 31 includes a plate body 311 and two rotating shafts 312. The plate body 311 is a long strip, and the two rotating shafts 312 are integrally disposed at both ends of the length of the plate body 311. A rotating seat is provided at the position corresponding to the rotating shaft 312 in the housing 10, and the rotating shaft 312 is mounted on the rotating seat so that the wind deflector 31 can rotate. Understandably, a motor is also provided in the housing 10, and the motor provides power for the rotation of the wind deflector 31. The motor is connected to the rotating shaft 312 for transmission. The rotation of the motor drives one of the wind deflectors 31 to rotate, and the other wind deflector 31 is driven by the connecting rod 32 so that the two wind deflectors 31 rotate synchronously to open and close the diversion air duct 11. This application has two motors, and the two motors are respectively adapted to two wind deflector components 30 to drive the wind deflectors 31 of the two wind deflector components 30 to rotate, thereby opening and closing the diversion air duct 11. It should be noted that in this embodiment, the rotating shaft 312 is located at the center position of the plate body 311.
[0037] like Figure 6 , Figure 8 and Figure 9 As shown, in an optional embodiment, the wind deflector 31 is provided with a plurality of locking posts 313 at intervals, and the housing 10 is provided with a plurality of buckles 13, each buckle 13 having a fastening groove 131, and the locking posts 313 fastening into the fastening groove 131.
[0038] Specifically, the wind deflector 31 of this application is relatively long, and only two connecting rods 32 at both ends are used to drive the two wind deflectors 31 to move synchronously. When the two wind deflectors 31 rotate, they will vibrate, especially in the middle of the wind deflector 31, where the vibration will be more severe. Multiple locking posts 313 are arranged at intervals along the length of the wind deflector 31. Each diversion duct 11 of this application has two parallel wind deflectors 31, and the locking posts 313 on the two wind deflectors 31 are arranged facing each other. Multiple buckles 13 are provided on the housing 10. The buckles 13 are perpendicular to the length direction of the two wind deflectors 31. Each buckle 13 has two fastening grooves 131. The distance between the two fastening grooves 131 is the distance between the axes of rotation 312 of the two wind deflectors 31, so that each of the two fastening grooves 131 corresponds to one wind deflector 31, and each fastening groove 131 fastens one locking post 313, thereby reducing the degree of vibration of the two wind deflectors 31 during rotation.
[0039] like Figure 3 and Figure 4 As shown, the inner wall of the diversion duct 11 has a step 111. When the wind baffle assembly closes the diversion duct 11, the wind baffle 31 is placed on the step 111.
[0040] Specifically, the inner wall of the diversion duct 11 has a step 111, and the baffle plate 31 near the step 111 rests on the step 111. Figure 3As shown, the baffle plate 31 is in the state of closing the diversion duct 11. At this time, the baffle plate 31 rests on the step 111, which is used to position the baffle plate 31 when closing the diversion duct 11. In this embodiment, when the diversion duct 11 is opened, the baffle plate 31 rotates clockwise to disengage. As the clockwise rotation angle of the baffle plate 31 gradually increases, the gap between the two baffle plates 31 also gradually increases. The gap between the two baffle plates 31 is at its maximum when the baffle plate 31 rotates to be parallel to the side wall of the diversion duct 11. When the diversion duct 11 is closed, the baffle plate 31 rotates counterclockwise to make the gap between the two baffle plates 31 smaller and smaller, and the two baffle plates 31 are in a straight line. At this time, the baffle plate 31 closer to the step 111 rests on the step 111 to close the diversion duct 11.
[0041] like Figures 3 to 5 As shown, in an optional embodiment, both diversion ducts 11 are rectangular cylindrical ducts. Both diversion ducts 11 are rectangular cylindrical, and their cross-sectional areas are approximately the same, so that their airflow effects are approximately the same. The included angle between the two diversion ducts 11 is in the range of 90°-130°. In this embodiment, when the diversion ducts 11 are closed, the two baffles 31 are approximately perpendicular to the inner wall of the diversion ducts 11. When the two baffles 31 are rotated clockwise by approximately 45° (see...),... Figure 4 The deflector 31 points forward, causing the airflow from the split duct 11 to converge towards the center, ensuring airflow directly in front of the air conditioner 100 and solving the problem of a dead zone with no airflow at the front. The airflow design of this application solves the problem of no airflow at the front, and the large angle between the two split ducts results in a larger airflow range from the air conditioner 100.
[0042] Please refer to this again. Figure 5 As shown, in an optional embodiment, the housing 10 has a volute tongue 14 and a volute plate 15, and one of the two split air ducts 11 is disposed in the extending direction of the volute tongue. The two split air ducts 11 are a first air duct 112 and a second air duct 113, respectively. The first air duct 112 is disposed in the extending direction of the volute tongue 14, and the second air duct 113 is disposed on one side of the volute plate 15, forming an angle with the first air duct 112. The air conditioner 100 also includes a guide plate 40, which is used to control the air volume of the first air duct 112 and the second air duct 113.
[0043] Specifically, the housing 10 has a volute tongue 14 and a volute plate 15. The first air duct 112 is located in the extending direction of the volute tongue 14. Therefore, most of the air delivered from the fan will flow towards the volute tongue 14, that is, most of the air will flow towards the first air duct 112. A guide plate 40 is located at the junction of the first air duct 112 and the second air duct 113. The guide plate 40 is used to control the airflow of the second air duct 113 and the first air duct 112 to be approximately the same. A guide surface 41 is provided on the side of the guide plate 40 facing the second air duct 113. The guide surface 41 blocks part of the airflow passing through the main air duct 12 and directs the airflow to the second air duct 113, so that the airflow of the second air duct 113 is the same as the airflow of the first air duct 112.
[0044] like Figure 5 As shown, in an optional embodiment, the air conditioner 100 further includes two grille plates 50, which are respectively disposed on the outer sides of the two wind deflector assemblies 30. Specifically, the two grille plates 50 are respectively disposed at the outlet positions of the first air duct 112 and the second air duct 113, and are disposed on the outer side of the wind deflector 31. The grille placement on the outer side of the wind deflector 31 makes the temperature gradient of the air outlet of the air conditioner 100 more uniform, thereby improving indoor comfort. Understandably, in this embodiment, louver assemblies 60 are disposed in the first air duct 112 and the second air duct 113. Air enters from the grille of the housing 10, undergoes heat exchange through the evaporator 70, passes through the impeller 20, enters the main air duct 12, then enters the first air duct 112 and the second air duct 113, and is blown out from the wind deflector 31. Finally, it is discharged through the grille plate 50 on the outer side of the wind deflector 31, so that the air conditioner can discharge uniform air, thereby improving the comfort of the indoor user.
[0045] Please refer to this again. Figure 1 and Figure 2 As shown, the air conditioner 100 also includes a panel 80, which is disposed on the front side of the housing 10. The outlets of the two branch air ducts 11 are located on both sides of the panel 80. Specifically, the housing 10 includes a base plate assembly 16 and a panel support assembly 17. Inside the housing 10, an evaporator 70, a fan wheel 20, an air outlet frame 90, a louver assembly 60, etc., are also disposed, and a main air duct 12 and a connected first air duct 112 and a second air duct 113 are formed inside the housing 10. The panel 80 is disposed on the side of the panel assembly facing forward, and the outlets of the first air duct 112 and the second air duct 113 are located on both sides of the width direction of the panel 80. This application provides air outlet through the first air duct 112 and the second air duct 113 on the left and right sides, with a large air outlet angle and no dead zones in the front air outlet, resulting in uniform air outlet.
