Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to an air conditioner. Background Art

[0002] The air outlet structure of the existing air conditioner is simple. Generally, a rotatable wind shield is set at the air outlet to meet the needs of air supply when the air conditioner is working and shielding the air outlet when not working. In order to realize the cooling and windless function of the air conditioner, usually, an air hole is set on the wind shield. When the cooling and windless function is turned on, the wind shield blocks the air outlet, and the air conditioner supplies air through the air hole. However, because the wind shield is tightly connected to the edge of the air outlet, the air flow inside the air conditioner is prone to oscillation due to changes in air pressure, and then it is easy to produce surging and abnormal sound phenomena, which aggravates the noise generated by the air conditioner.

[0048] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0049] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0050] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0051] At present, in order to realize the cooling and windless function of the air conditioner, usually, an air hole is provided on the wind shield. When the cooling and windless function is turned on, the wind shield blocks the air outlet, and the air conditioner supplies air through the air holes. However, since the wind shield is tightly connected to the edge of the air outlet, no air can leak. Or, due to factors such as processing errors, a tiny gap is left between the wind shield and the edge of the air outlet, and very little air leaks. In the process of the air conditioner supplying air through the air holes, the air flow inside the air conditioner is prone to oscillation due to the sudden change of air pressure, and then it is easy to produce surging and abnormal sound phenomenon, which aggravates the noise generated by the air conditioner.

[0052] In view of the above problems, the utility model provides an air conditioner.

[0053] See also Figures 1 to 5In an embodiment of the utility model, the air conditioner includes a housing 10, a windshield 20 and a driving member 40. The housing 10 is provided with an air outlet 114. The windshield 20 extends in the up-down direction of the housing 10. The windshield 20 is rotatably arranged at the air outlet 114 and has a plurality of air holes 21. The driving member 40 is arranged at the housing 10 and is transmission-connected with the windshield 20 so that the windshield 20 rotates to open or cover the air outlet 114. The inner wall of the air outlet 114 is provided with at least A supporting rib 115. When the wind shield 20 blocks the air outlet 114, the wind shield 20 abuts against the supporting rib 115, and a first wind gap 27 is formed between one end of the wind shield 20 close to the inner wall of the air outlet 114 and the inner wall of the air outlet 114. In this way, a proper amount of airflow can leak out through the first wind gap 27, so as to achieve the effect of balancing the air duct pressure of the air conditioner in a windless state, thereby helping to reduce the possibility of surging noise in the air duct and improving the user's windless experience.

[0054] The air holes 21 provided on the wind shield 20 are of a microporous structure to prevent the air holes 21 from being too large and reducing the windless effect. The air holes 21 are staggered on the wind shield 20 to fully utilize the opening area of ​​the wind shield 20. While ensuring the structural stability of the wind shield 20, the air flow is evenly dispersed. Combined with the microporous design of the air holes 21, the air conditioner has a better windless function.

[0055] When the air outlet 114 is opened, the end of the wind shield 20 close to the inner wall of the air outlet 114 is roughly parallel to the air supply direction, ensuring the stable blowing of the airflow with a large air volume; when the air outlet 114 is closed, because the support rib 115 is arranged on the closing path of the wind shield 20, it is ensured that the end of the wind shield 20 close to the inner wall of the air outlet 114 is in direct contact with the support rib 115, rather than directly abutting against the inner wall of the air outlet 114, thereby reliably ensuring that when the air outlet 114 is covered, a first air gap 27 can be formed between the end of the wind shield 20 close to the inner wall of the air outlet 114 and the inner wall of the air outlet 114, so that part of the duct cold air can be blown out through the first air gap 27, effectively balancing the internal and external air pressures, reducing the occurrence of turbulence, and reducing the noise generated by the collision of the airflow with the wind shield 20 and the housing 10, thereby reducing the noise generated by the air conditioner. Among them, the support rib 115 can be convexly arranged on the inner wall of the air outlet 114. Of course, in other embodiments, the supporting ribs 115 can be disposed on the wind shield 20 while ensuring the normal use of the wind shield 20 .

[0056] In the technical solution of the present utility model, by arranging support ribs 115 on the inner wall of the air outlet 114, when the wind shield 20 blocks the air outlet 114, the wind shield 20 rests on the support ribs 115 and cannot be tightly overlapped on the inner wall of the air outlet 114, so as to form a first wind gap 27 between one end of the wind shield 20 close to the inner wall of the air outlet 114 and the inner wall of the air outlet 114. Furthermore, when the air conditioner turns on the windless function, a part of the airflow is blown out from the vents 21 on the wind shield 20 to meet the user's demand for windless feeling, and the other part of the airflow leaks out through the first wind gap 27, which reliably balances the internal air duct pressure, reduces the possibility of surging noise in the air duct, reduces the noise generated by the air conditioner, and helps to improve the user's experience.

[0057] See also Figures 6 to 7 In an embodiment of the utility model, in the vertical direction of the air conditioner, a plurality of support ribs 115 are arranged at intervals. It can be understood that since the wind shield 20 extends in the up-down direction of the air conditioner and can reliably block the air outlet 114, the support ribs 115 can be arranged in the up-down direction of the shell 10, and a plurality of support ribs 115 are arranged at intervals. Each support rib 115 can be abutted against one end of the wind shield 20 close to the inner wall of the air outlet 114. In this way, the first wind gaps 27 arranged in the up-down direction of the shell 10 help to disperse the airflow, balance the air pressure in the air duct, improve the noise reduction efficiency, and ensure the user's windless experience.

[0058] When the air conditioner turns on the windless function, the wind shield 20 closes the air outlet 114 and allows the internal air flow to blow outward through the vent 21. Since a first wind gap 27 is left between the end of the wind shield 20 close to the inner wall of the air outlet 114 and the inner wall of the air outlet 114, the cold air in the air duct will leak out from the first wind gap 27 in an appropriate amount to balance the air pressure in the air duct and reduce or eliminate the hidden danger of surging and abnormal noise in the air duct. Since the cold air will sink, in an embodiment of the utility model, the supporting ribs 115 extend from bottom to top and tilt outward, wherein the supporting ribs 115 are upward from bottom to top and in a direction away from the inner cavity of the shell 10, and can guide the cold air leaking through the first wind gap 27 upward. With this arrangement, the cold air can be transported to a farther distance after being blown out, which helps to improve the cooling and heat exchange effect.

[0059] Furthermore, if Figure 8As shown, the inclination angle of the support rib 115 is a, 10°≤a≤60°, that is, the angle a between the support rib 115 and the horizontal plane satisfies 10°≤a≤60°. When the angle is too small, that is, a<10°, because the support rib 115 is approximately parallel to the horizontal plane, the air supply direction of the cold air remains basically unchanged, and the cold air cannot be delivered to a farther distance. When the angle is too large, that is, a is greater than 60°, the diffusion of the cold air is easily blocked due to environmental factors such as the floor height and the structure of the air conditioner itself, which is not conducive to improving the heat exchange effect. Therefore, the specific value of the inclination angle of the support rib 115 can be 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, etc., but according to experiments, limiting the inclination angle of the support rib 115 to between 10° and 60° can make the air conditioner have higher refrigeration and heat exchange performance.

[0060] Optionally, compared with the air leakage gap between the end of the wind shield 20 close to the inner wall of the air outlet 114 and the inner wall of the air outlet 114 due to assembly errors and processing errors, the air leakage gap is generally not more than 0.5mm, the air leakage is very little, the air pressure balancing effect is poor, and the noise is high. In an embodiment of the utility model, the spacing s of the first air gap 27 satisfies: 2mm≤s≤4mm; that is, by utilizing the setting of the supporting rib plate, the inner wall of the air outlet 114 and the end of the wind shield 20 close to the inner wall of the air outlet 114 are separated, so as to achieve the purpose of appropriate air leakage to balance the air pressure in the air duct, thereby reducing the possibility of the air conditioner generating noise.

[0061] Among them, when the spacing of the first air gap 27 is less than 2mm, due to the small spacing, the effect of smooth airflow is poor, it is easy to increase noise, and affect the user's comfort; when the spacing of the first air gap 27 is greater than 4mm, due to the large spacing, under the condition of large air volume, there is more air leakage, which is easy to reduce the user's windless experience. Therefore, the specific value of the spacing of the first air gap 27 can be s, which can be specifically 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, etc., but according to experiments, it can be obtained that the gap of the first air gap 27 is limited to between 2mm and 4mm, which can have a better low noise effect and a better windless air outlet effect, improving the user's experience.

[0062] See also Figures 4 to 5In the embodiment of the utility model, the inner wall of the air outlet 114 is provided with an avoidance step 113a, and the support ribs 115 are provided on the avoidance step 113a. Such a configuration not only ensures that the windshield 20 is overlapped on the avoidance step 113a through the support ribs 115, but also facilitates the use of the avoidance step 113a to form an avoidance space, thereby reducing the risk of interference between the windshield 20 and the housing 10 and improving the rotation reliability of the windshield 20. Of course, in other embodiments, the inner wall of the air outlet 114 is not provided with the avoidance step 113a.

[0063] See also Figures 9 to 15 In an embodiment of the utility model, a plurality of windshield plates 20 are provided, and one of the windshield plates 20 is connected to the driving member 40, and each windshield plate 20 is connected to each other by a connecting rod 30. In this way, the windshield plates 20 are driven by a single driving member 40 and synchronously linked by the connecting rod 30, which helps to simplify the structure and reduce the number of driving members 40 and related components. At the same time, it ensures the synchronous rotation of each windshield plate 20 and improves the driving efficiency.

[0064] Due to the connection of the connecting rod 30 and the abutment between the wind shield 20 and the inner wall of the air outlet 114, because the wind shields 20 are arranged at intervals on the connecting rod 30, when two adjacent wind shields 20 are driven to rotate and approach each other, compared with the close fit between the two adjacent wind shields 20, in an embodiment of the utility model, when the wind shield 20 blocks the air outlet 114, a second wind gap 28 is formed between the two adjacent wind shields 20, so that part of the air flow can be blown out through the second wind gap 28, further balancing the internal and external air pressure, reducing or eliminating the hidden danger of surging noise in the air duct, and improving the noise reduction effect of the air conditioner.

[0065] Among them, the spacing of the second air gap 28 is consistent with the spacing of the first air gap 27, that is, the spacing of the second air gap 28 is greater than or equal to 2 mm and less than or equal to 4 mm, ensuring that the air conditioner has better low noise and better windless air outlet effect.

[0066] Specifically, the windshield 20 is provided with a first connecting shaft 22, and the connecting rod 30 is provided with a first connecting slot 31 that is engaged with the first connecting shaft 22, that is, the engagement between the first connecting shaft 22 and the first connecting slot 31 improves the connection convenience and connection strength between the windshield 20 and the connecting rod 30. Fig.11 and Fig.12As shown, the connecting rod 30 includes a rod body and a claw arranged on the rod body, and two claws are symmetrically arranged and enclosed with the rod body to form a first connecting groove 31. When the first connecting shaft 22 is pressed into the first connecting groove 31, the deformable characteristics of the connecting rod 30 are utilized, which not only facilitates the assembly between the wind shield 20 and the connecting rod 30, but also ensures a stable connection between the wind shield 20 and the connecting rod 30; the number of the first connecting grooves 31 is set corresponding to the number of wind shields 20, ensuring that one connecting rod 30 is connected to multiple wind shields 20 at the same time.

[0067] Furthermore, the bottom wall of the first connecting slot 31 is provided with an auxiliary notch 32, which thins the rod body, facilitates the deformation of the claw, improves the assembly convenience of the windshield 20 and the connecting rod 30, and can also extend the service life of the connecting rod 30. However, in other embodiments, structural members that can connect the windshields 20 without affecting the rotation of the windshields 20 are also applicable to the utility model.

[0068] In order to ensure efficient driving of each windshield plate 20, in the embodiment of the present utility model, as shown in FIG. Fig. 9 As shown, two connecting rods 30 are provided in the length direction of the wind shield 20 , and the two connecting rods 30 are arranged at intervals along the up and down directions of the shell 10 , and are respectively arranged close to the two ends of the wind shield 20 , so as to improve the rotation stability and rotation synchronization of each wind shield 20 .

[0069] See also Fig. 9 and Fig.13 In an embodiment of the utility model, at least one support rod 116 is further provided on the shell 10. The support rod 116 is arranged away from the connecting rod 30 and is rotatably connected to the wind shield 20. This can further improve the rotation stability and rotation synchronization of each wind shield 20.

[0070] Among them, the support rod 116 is arranged near the middle area of ​​the wind shield 20 to stabilize the middle area of ​​the wind shield 20, cooperates with the setting of the connecting rod 30 to strengthen the connection between the wind shields 20, and cooperates with the setting of the support rod 116 connecting the shell 10 to strengthen the assembly strength of each wind shield 20 on the shell 10.

[0071] Specifically, the wind shield 20 is provided with a second connecting shaft 23, and the support rod 116 is provided with a second connecting groove 116b which is engaged with the second connecting shaft 23, wherein the support rod 116 includes a rod body and a fastener 116a provided on the rod body, and a second connecting groove 116b is formed between the fastener 116a and the rod body. When the second connecting shaft 23 is pressed into the second connecting groove 116b, the deformable characteristics of the fastener 116a are utilized to facilitate the assembly between the wind shield 20 and the support rod 116, and to ensure a stable connection between the wind shield 20 and the support rod 116; the number of the second connecting grooves 116b is set corresponding to the number of wind shields 20, ensuring that one support rod 116 is connected to multiple wind shields 20 at the same time.

[0072] Furthermore, a portion of the support rod 116 provided with the fastener 116 a protrudes toward the windshield 20 , so as to facilitate the connection between the support rod 116 and the windshield 20 while avoiding interference.

[0073] See also Fig.15 In an embodiment of the utility model, a mounting groove 24 is provided on the side wall of the wind shield 20 facing the support rod 116, and the second connecting shaft 23 is provided in the mounting groove 24. In this way, the support rod 116 is connected to the wind shield 20 and partially embedded in the wind shield 20, thereby reducing the space occupied by this position.

[0074] In addition, the axes of the first connecting shaft 22 and the second connecting shaft 23 do not overlap, which can improve the connection stability and rotation reliability of the wind shield 20 to a certain extent.

[0075] See also Figure 1 , Figure 3 and Figure 7 The housing 10 includes an upper panel 12, a lower panel 13, a top cover 14, an air outlet frame 11, a chassis 15 and a back plate 16. The air outlet frame 11 is arranged between the upper panel 12 and the back plate 16, and is located above the lower panel 13. The back plate 16 is provided with an air inlet 16a. An evaporator 18 and an air duct component 17 are arranged in the housing 10. In this way, the air flow enters the housing 10 from the air inlet 16a, is processed by the evaporator 18, and is blown to the air outlet 114 of the air outlet frame 11 through the action of the air duct component 17. The air flow flowing to the air outlet 114 is blown outward through the air vent 21, the first air gap 27 and the second air gap 28, so that the air conditioner achieves a low-noise, windless air outlet effect.

[0076] In the embodiment of the utility model, the air outlet frame 11 includes a base 112, a top plate 111, and two side plates 113 arranged between the base 112 and the top plate 111, the wind shield 20 is rotatably connected between the base 112 and the top plate 111, at least one of the two side plates 113 is formed with the air outlet 114, and the supporting rib 115 is provided to ensure that when the wind shield 20 blocks the air outlet 114, one end of the wind shield 20 close to the inner wall of the air outlet 114 abuts against the supporting rib The support ribs 115 ensure that when the windless function is turned on, a first air gap 27 is always left between the wind shield 20 and the inner wall of the air outlet 114, and a second air gap 28 is always left between two adjacent wind shields 20. In addition to the cold air blown out through the vents 21, the rest of the cold air can be blown out through the first air gap 27 and the second air gap 28. With the upward guiding effect of the support ribs 115, the cold air can be transported to a farther distance, improving the heat exchange effect and reducing noise, thereby improving the user's comfort. When both side panels 113 are formed with air outlets 114, the air conditioner is configured as a double-flow air conditioner.

[0077] Specifically, the driving member 40 is fixed on the top plate 111, and a first driving shaft 25 is provided at one end of the windshield 20, and the first driving shaft 25 passes through the top plate 111 and is transmission-connected to the driving member 40, and a second driving shaft 26 is provided at the other end to be plugged and matched with the base 112. It can be understood that the driving member 40 is configured as a motor, and the top plate 111 is provided with a first shaft hole 111a and a motor mounting hole 111b, wherein the first shaft hole 111a is opened corresponding to the windshield 20 and is provided for the first driving shaft 25 to pass through, ensuring that a first driving shaft 25 passes through the top plate 111 and the driving member 40. The first drive shaft 25 is connected to the top plate 111 through transmission connection, and the remaining first drive shaft 25 passes through the top plate 111 and is limited to the top plate 111, which helps to constrain the position of each wind shield 20 on the top plate 111 and provide assistance for the reliable rotation of the subsequent wind shield 20; the motor mounting hole 111b is used to assist in fixing the driving member 40 through fasteners to ensure the reliable assembly of the driving member 40 on the top plate 111; the base 112 is provided with a second shaft hole 112a aligned with the first shaft hole 111a, so that the second drive shaft 26 of the wind shield 20 is inserted into the second shaft hole 112a, ensuring that the wind shield 20 can rotate relative to the air outlet frame 11.

[0078] In addition, since the motor surface is prone to carry current, in the embodiment of the present utility model, Figures 9 to 10 As shown, the first driving shaft 25 and the driving member 40 are connected via an anti-electricity shaft 41, wherein the first driving shaft 25 is provided with a mounting shaft hole 251 for inserting the anti-electricity shaft 41, which can not only ensure that the motor drives the wind shield 20, but also effectively prevent the current from being conducted from the motor to the wind shield 20, thereby reducing damage to other components in the air conditioner and preventing the surface of the wind shield 20 from absorbing a large amount of dust and affecting the air supply effect.
