Description

Technical Field

[0002] In the related art, a rotatable air guide strip is usually provided at the air outlet of the indoor unit of the air conditioner. The air guide strip can change the air supply angle but will also cause air supply resistance. When the air conditioner is in the windless mode, the wind resistance caused by the air guide strip is further increased, so the air volume in the windless mode will become smaller, and the cooling effect of the air conditioner will also decrease accordingly. Although the windless mode achieves the effect of not blowing cold air directly on people, due to its small air volume and small air supply angle, it will cause a narrow air supply range and a short air supply distance, resulting in a large temperature difference between places far away from the air conditioner and places close to the air conditioner, which makes the indoor temperature uneven and the comfort level poor.

[0055] The embodiment of the present invention provides an air conditioner indoor unit. Figures 1 to 22 The air conditioner indoor unit of the present invention is described in detail.

[0056] It should be noted that the air conditioner indoor unit of the present invention can be a wall-mounted air conditioner indoor unit, a floor-standing air conditioner, etc. The following description takes a floor-standing air conditioner indoor unit as an example. According to the content disclosed in the present invention, ordinary technicians in this field can easily think of the specific structure when the air conditioner indoor unit is other types of indoor units.

[0057] In one embodiment of the present invention, Figures 1 to 11 As shown, the air conditioner indoor unit includes:

[0058] A housing 100, wherein the housing 100 is provided with an air inlet 101 and an air outlet 102, and an air duct is formed between the air inlet 101 and the air outlet 102;

[0059] An air guide frame 300 is installed on the housing 100 and is arranged corresponding to the air outlet 102. The air guide frame 300 is connected front to back to form an air guide port connected to the air duct. A plurality of air guide strips 340 are arranged in the air guide port; and

[0060] The first driving mechanism 400 is installed in the shell 100 . The first driving mechanism 400 is connected to the air guide frame 300 . The first driving mechanism 400 is used to drive the air guide frame 300 to move forward and backward along the air outlet direction so as to extend out of the air outlet 102 or move back into the air outlet 102 .

[0061] Specifically, the air conditioner indoor unit further includes a heat exchanger 700 and a fan 600, wherein the heat exchanger 700 is located between the air inlet 101 and the fan 600, and the fan 600 is used to drive air from the air inlet 101 into the air duct, and after passing through the heat exchanger 700 for heat exchange, the air is blown out from the air outlet. A volute and a volute tongue are provided between the fan 600 and the air outlet 102, and the volute and the volute tongue are arranged to form an air outlet duct, so that the air flow is concentrated to flow out from the air outlet 102, and the air outlet pressure is increased.

[0062] In this embodiment, an air guide frame 300 is provided at the air outlet 102, and a rotatable air guide strip 340 is provided in the air guide frame 300 to achieve variable air supply angle. A plurality of through holes 341 are provided on the air guide strip 340, and the through holes 341 are connected to the air duct. It can be understood that the air guide strip 340 can open the air guide port or close the air guide port. When the air guide strip 340 closes the air guide port, the air flow mainly flows out from the through holes 341 and does not blow directly to the user, thereby achieving windless air supply.

[0063] In the related art, when the air guide strip rotates from the state of opening the air guide port to the state of closing the air guide port, the air supply resistance gradually increases, and the air supply angle and range gradually decrease, until the air guide strip closes the air guide port, that is, the air conditioner is in the windless mode, the wind resistance further increases, the air volume will become very small, and the cooling effect of the air conditioner will also drop sharply. Although the windless mode achieves the effect of not blowing cold air directly on people, due to the small air volume, small air supply angle and short air supply distance, the temperature difference between the places far away from the air conditioner and the places close to the air conditioner is large, which makes the indoor temperature uneven and the comfort level poor.

[0064] The present invention proposes an air conditioner indoor unit, in which a housing 100 is provided with an air guide frame 300 and a first driving mechanism 400, the air guide frame 300 is arranged corresponding to the air outlet 102, and a plurality of air guide strips 340 are arranged in the air guide frame 300, and the air guide frame 300 is driven by the first driving mechanism 400 to move forward and backward along the air outlet direction, so that the air guide frame 300 extends out of the air outlet 102 or moves back into the air outlet 102. It can be understood that when the air conditioner is in the windless mode, the first driving mechanism 400 can push the air guide frame 300 outward, and can effectively realize the air outlet from both sides of the air guide frame 300, and the air outlet angle can reach 180 degrees, which significantly increases the air supply range, air supply distance and air outlet volume in the windless mode, thereby improving the uniformity and comfort of the indoor temperature in the windless mode. Therefore, the air conditioner indoor unit of the present invention has the advantages of large air supply angle, long air supply distance and large air outlet volume in the windless mode.

[0065] It should be noted that when the air conditioner is in the windless mode, Figure 7 As shown, the first driving mechanism 400 can push the air guide frame 300 outward. Figure 6As shown, the first driving mechanism 400 can also push the air guide frame 300 outward to increase the air supply angle and air supply range. Of course, when the air conditioner is in other air supply modes, such as Figure 3 As shown, the first driving mechanism 400 can also move the air guide frame 300 back into the air outlet 102 to avoid excessive air flow, which may cause a sudden drop in indoor temperature and waste of energy.

[0066] In this embodiment, Figure 6 As shown, when the air guide frame 300 is in a state of extending out of the air outlet 102, the air guide frame 300 is partially located in the air duct in the air outlet direction, and an air outlet channel is formed between the air guide frame 300 and the side wall of the air duct. Specifically, an air outlet channel is formed between the left side wall of the air guide frame 300 and the left side wall of the air duct, and another air outlet channel is formed between the right side wall of the air guide frame 300 and the right side wall of the air duct. The two air outlet channels are located on both sides of the air guide frame 300. In this way, when the first driving mechanism 400 drives the air guide frame 300 to be pushed outward, air can be discharged from both sides of the air guide frame 300, thereby increasing the air supply angle, air supply range and air outlet volume of the air conditioner indoor unit. Of course, in other embodiments, when the air guide frame 300 is in a state of extending out of the air outlet 102, the air guide frame 300 can also be completely located outside the air duct in the air outlet direction, and air can also be discharged from both sides of the air guide frame 300.

[0067] In this embodiment, Figures 6 to 10 As shown, the housing 100 is provided with an air outlet frame 200, the air outlet frame 200 is connected front to back to form the air outlet 102, and the air guide frame 300 is installed on the air outlet frame 200 so as to be movable back and forth. Of course, in other embodiments, the air outlet frame 200 may not be provided in the housing 100, and the air guide frame 300 is directly installed in the housing 100 so as to be movable back and forth. However, the technical solution of this embodiment can increase the strength of the housing 100 at the air outlet 102 by providing the air outlet frame 200 in the housing 100, so as to prevent the air guide frame 300 from directly damaging the housing 100 when it is frequently moved at the air outlet 102; on the other hand, it provides an installation position for the first driving mechanism 400 and other structures, so as to improve the stability of the air guide frame 300 during movement.

[0068] In this embodiment, Figures 8 to 10As shown, the air outlet frame 200 includes an upper end plate 210, a lower end plate 220, and two first side plates 230 that are oppositely arranged and connect the upper end plate 210 and the lower end plate 220, and the air guide frame 300 includes an upper end seat 310, a second end plate, and two second side plates 330 that are oppositely arranged and connect the upper end seat 310 and the lower end seat 320. When the air guide frame 300 is in a state of extending out of the air outlet 102, an air outlet channel is formed between each first side plate 230 and the corresponding second side plate 330. Specifically, an air outlet channel is formed between the first side plate 230 and the second side plate 330 located on the left side of the air guide frame 300, and another air outlet channel is formed between the first side plate 230 and the second side plate 330 located on the left side of the air guide frame 300.

[0069] Furthermore, the shape of the air guide frame 300 matches the shape of the air outlet frame 200. It can be understood that since the air guide frame 300 needs to move freely relative to the air guide frame 300, by making the shapes of the two match, on the one hand, it can be avoided that the air outlet frame 200 interferes with the air guide frame 300 during the movement of the air guide frame 300, so that the air guide frame 300 moves unsmoothly; on the other hand, it can be avoided that when the air guide frame 300 moves back into the air outlet frame 200, the gap between the two is too large, causing part of the air flow to be sent out from the air guide port, while part of it is poured into the gap to generate noise. Specifically, the cross-section of the air guide frame 300 and the air outlet frame 200 can be in the shape of a trapezoid, a fan, a quasi-trapezoidal or a quasi-fan shape, etc. The present invention does not limit the specific shapes of the air guide frame 300 and the air outlet frame 200.

[0070] In addition, the spacing between the two first side panels 230 and the spacing between the two second side panels 330 gradually increase along the air outlet direction. In other words, the air outlet 102 and the air guide port are both flared structures. In this way, on the one hand, the air guide frame 300 can be easily moved out of the air outlet frame 200, and also easily moved into the air outlet frame 200; on the other hand, when the air guide extends out of the air outlet frame 200, the air outlet gap formed on both sides of the air guide frame 300 also gradually increases along the air outlet direction, which is conducive to expanding the air supply range and increasing the air output in the windless mode.

[0071] Furthermore, if Figure 7As shown, each of the first side panels 230 includes a first side edge 231, a second side edge 232, and a first folded edge 233 connecting the first side edge 231 and the second side edge 232, the spacing between the two second side edges 232 is greater than the spacing between the two second side edges 232, each of the second side panels 330 includes a third side edge 331 and a second folded edge 332 connected to the outside of the third side edge 331, and the first folded edge 233 is used to limit the second folded edge 332 when the air guide frame 300 moves back into the air outlet frame 200. In this embodiment, the first folded edge 233 and the second folded edge 332 both extend horizontally in the left and right directions. In this way, when the air guide frame 300 extends out of the air outlet frame 200, the second folded edge 332 can guide the airflow on both sides of the air guide frame 300 to the left and right directions, avoiding direct blowing toward the front of the air conditioner, achieving windless air supply while increasing the air supply volume. When the air guide frame 300 moves back to the air outlet frame 200, the second folded edge 332 will limit the first folded edge 233. When the second folded edge 332 abuts against the first folded edge 233, the air guide frame 300 is prevented from continuing to move backward, thereby preventing the air guide frame 300 from excessive displacement due to inertial movement. In addition, when the air guide frame 300 moves back to the air outlet frame 200, the side edges and folded edges of the air guide frame 300 cooperate with the side edges and folded edges of the air outlet frame 200 to achieve a seal between the two, thereby avoiding a gap between the air guide frame 300 and the air outlet frame 200, causing part of the airflow to be sent out from the air guide port, while part of the airflow is poured into the gap to generate noise.

[0072] like Figures 8 to 10 As shown, the first driving mechanism 400 includes a first driving member 410, and the first driving member 410 is connected to the upper end seat 310; and / or, the first driving mechanism 400 includes a second driving member 420, and the second driving member 420 is connected to the lower end seat 320. In this embodiment, the upper and lower ends of the air guide frame 300 are connected with driving members to increase the driving force of the air guide frame 300 to move forward and backward, and improve the balance and stability of the air guide frame 300 to move forward and backward. Of course, in other embodiments, the driving member can be connected only to the upper end or the lower end of the air guide frame 300.

[0073] Furthermore, the upper end plate 210 is provided with an upper sliding groove 211 extending along the air outlet direction, and the upper end plate 210 is provided with an upper sliding shaft 311 connected to the first driving member 410, and the upper sliding shaft 311 is installed in the upper sliding groove 211 for forward and backward movement; and / or, the lower end plate 220 is provided with a lower sliding groove 221 extending along the air outlet direction, and the lower end seat 320 is provided with a lower sliding shaft 321 connected to the second driving member 420, and the lower sliding shaft 321 is installed in the lower sliding groove 221 for forward and backward movement. It can be understood that the first driving member 410 is arranged above the air outlet frame 200, and the second driving member 420 is arranged below the air outlet frame 200. In order to establish a connection between the first driving member 410 and the second driving member 420 and the air guide frame 300, an upper sliding groove 211 is provided on the upper end plate 210 of the air outlet frame 200, so that the upper sliding shaft 311 at the upper end of the air guide frame 300 can be slidably installed, and the upper sliding shaft 311 is passed through and connected with the first driving member 410; similarly, a lower sliding groove 221 is provided on the lower end plate 220 of the air outlet frame 200, so that the lower sliding shaft 321 at the lower end of the air guide frame 300 can be slidably installed, and the lower sliding shaft 321 is passed through and connected with the second driving member 420. The technical solution of this embodiment can enable the air guide frame 300 to move freely forward and backward, and at the same time, establish a connection between the air guide frame 300 and the air outlet frame 200, thereby improving the stability of the movement of the air guide frame 300.

[0074] For details, please refer to Fig.11 As shown, the first driving member 410 includes a first motor 411, a first gear 412 and a first rack 413, the first motor 411 is connected to the first gear 412, the first gear 412 is meshed with the first rack 413, and the first rack 413 is connected to the upper sliding shaft 311; and / or, the second driving member 420 includes a second motor, a second gear and a second rack, the second motor is connected to the second gear, the second gear is meshed with the second rack, and the second rack is connected to the upper sliding shaft 311. In the technical solution of this embodiment, the motor rotates through the gear, thereby driving the rack to move linearly, thereby pulling the sliding shaft to move forward and backward along the sliding groove, and finally driving the air guide frame 300 to move forward and backward.

[0075] Furthermore, if Figures 8 to 10 As shown, the air inlet side of the air outlet frame 200 is provided with a plurality of louvers 240, and the plurality of louvers 240 are arranged in the up-down direction. In the air outlet direction, the louvers 240 are located upstream of the air guide strip 340. It can be understood that by rotating the air guide strip 340, the air outlet direction can be adjusted left and right, and by swinging the louvers 240 up and down, the air outlet direction can be adjusted up and down. The louvers 240 can be driven manually by the user to swing up and down, or the louvers 240 can be driven automatically by the driving member to swing, and the purpose is to swing the louvers 240 to the corresponding air outlet angle according to the user's needs.

[0076] Furthermore, an air guide strip driving member 350 is further provided at the upper end and / or the lower end of the air guide frame 300. The air guide strip driving member 350 is connected to at least one air guide strip 340. The multiple air guide strips 340 are linked to each other through a connecting rod 360. The air guide strip driving member 350 is used to drive the multiple air guide strips 340 to rotate axially in the up-and-down direction. In this embodiment, the air guide strip driving member 350 is a motor. A motor is respectively installed in the upper end seat 310 and the lower end seat 320 of the air guide frame 300. The two motors are respectively connected to the two ends of one of the air guide strips 340. When the motor drives the air guide strip 340 to rotate, driven by the connecting rod 360, the other air guide strips 340 also rotate accordingly, thereby realizing the linkage of all the air guide strips 340.

[0077] In another parallel embodiment, Figures 12 to 22 As shown, the air conditioner indoor unit further includes a second driving mechanism 500, which is connected to the air guide frame 300, and the second driving mechanism 500 is used to drive the air guide frame 300 to rotate with the up and down direction of the air conditioner indoor unit as the axial direction. Specifically, the second driving mechanism 500 includes a third driving member 510, which is connected to the upper end of the air guide frame 300; and / or, the second driving mechanism 500 includes a fourth driving member 520, which is connected to the lower end of the air guide frame 300. In this embodiment, different from the previous embodiment, the third driving member 510 is installed on the top of the upper end seat 310, the upper sliding shaft 311 is installed on the top of the third driving member 510, and the upper sliding shaft 311 is connected to the first driving member 410; the fourth driving member 520 is installed on the bottom of the lower end seat 320, and the lower sliding shaft 321 is set at the bottom of the fourth driving member 520, and the lower sliding shaft 321 is connected to the second driving member 420. That is, a third driving member 510 and a fourth driving member 520 are additionally provided between the end of the air outlet frame 200 and the end of the air guide frame 300 to drive the air guide frame 300 to rotate in the up-and-down direction as the axial direction.

[0078] Specifically, if Figures 12 to 15 As shown, when the first driving mechanism 400 drives the air guide frame 300 to move back into the air outlet frame 200, the upper sliding shaft 311 and the lower sliding shaft 321 both move backward, and the second driving mechanism 500 and the air guide strip driving member 350 also move back into the air outlet frame 200; Figures 16 to 19 As shown, when the first driving mechanism 400 drives the air guide frame 300 to extend out of the air outlet frame 200, the upper sliding shaft 311 and the lower sliding shaft 321 both move forward, and the second driving mechanism 500 and the air guide strip driving member 350 also extend out of the air outlet frame 200.

[0079] It should be noted that, when the first driving mechanism 400 pushes the air guide frame 300 out of the air outlet 102, air is discharged from both sides of the air guide frame 300, wherein the air pressure of the air outlet close to the volute tongue is greater than the air pressure of the air outlet close to the volute shell. Therefore, if the air guide frame 300 does not rotate and is set at the middle position of the air outlet 102, the air outlet on both sides of the air guide frame 300 is not uniform. The technical solution of this embodiment drives the air guide frame 300 to rotate left and right after the first driving mechanism 400 pushes the air guide frame 300 out, and then drives the air guide frame 300 to rotate left and right through the second driving mechanism 500. On the one hand, it can effectively adjust the air volume on the left and right sides of the air guide frame 300, so that the air volume and air speed on both sides of the air guide frame 300 are equivalent, thereby further improving the uniformity and comfort of the indoor temperature in the windless mode; on the other hand, it can change the blowing direction of the air guide frame 300, so that the air conditioner still has a variety of blowing directions in the windless mode, increasing the diversity of blowing modes available for users to choose.

[0080] The embodiment of the present invention further provides an air conditioner, the air conditioner comprising an air conditioner outdoor unit and the aforementioned air conditioner indoor unit, the air conditioner indoor unit being connected to the air conditioner outdoor unit via a refrigerant pipe.
