Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an air conditioner. Background Technology

[0002] In related technologies, air conditioners with two air outlets, one on the left and one on the right, offer a wider airflow angle. However, during operation, the airflow after heat exchange is directed to the left and right sides, resulting in less airflow directly in front of the air conditioner and a poorer airflow experience for those directly in front. This leads to poorer temperature regulation in front of the air conditioner and less uniform indoor temperature. Therefore, this issue needs to be addressed. Utility Model Content

[0061] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0062] The following is for reference. Figures 1-25 This invention describes an air conditioner according to an embodiment of the present invention.

[0063] Reference Figures 1-3 According to an embodiment of the present invention, an air conditioner includes a housing assembly 10 and a heat exchange and air supply assembly 20. The housing assembly 10 includes a main housing assembly 1 and a front panel assembly 2. The front panel assembly 2 is connected to the front end of the main housing assembly 1. The housing assembly 10 has an air inlet 111, a main air duct, and two main air outlets 13. The two main air outlets 13 are located at the front end of the housing assembly 10 and are respectively located on the left and right sides of the front panel assembly 2. The main air duct connects the air inlet 111 and the main air outlets 13. The front panel assembly 2 has a secondary air outlet 251 and a secondary air duct 22. The secondary air duct 22 connects the main air duct and the secondary air outlet 251. The secondary air outlet 251 is located on the front side of the front panel assembly 2 and is disposed inside the main housing assembly 1. The heat exchange and air supply assembly 20 includes a heat exchanger assembly and an air duct assembly 201.

[0064] When the air conditioner is working, the air duct assembly 201 can drive the airflow through the air inlet 111 into the interior of the casing assembly 10 and flow toward the heat exchanger assembly. After heat exchange in the heat exchanger assembly, the airflow flows to the main air duct. The airflow after heat exchange in the main air duct can flow out to the room through the two main air outlets 13 to regulate the indoor temperature. The two main air outlets 13 can increase the air outlet area of ​​the air conditioner, which is beneficial to improve the air outlet efficiency of the air conditioner and can also make the air outlet angle of the air conditioner wider to cover more indoor areas.

[0065] The front panel assembly 2 has a secondary air outlet 251 and a secondary air duct 22, with the secondary air duct 22 connecting the main air duct and the secondary air outlet 251. This allows at least a portion of the airflow after heat exchange in the main air duct to be blown out of the secondary air outlet 251 into the room. Furthermore, since the front panel assembly 2 is located on the front side of the housing assembly 10 and the two main air outlets 13 are located on the left and right sides of the front panel assembly 2, the air blown out of the secondary air outlet 251 can be closer to the front center of the air conditioner. This can effectively regulate the temperature in front of the air conditioner, enhance the uniformity of the indoor temperature, and thus improve the user experience.

[0066] According to the embodiment of the present invention, the air conditioner includes a main housing assembly 10 and a front panel assembly 2 located at the front end of the main housing assembly 10. The housing assembly 10 has two main air outlets 13 located on the left and right sides of the front panel assembly 2, which can make the air supply angle of the air conditioner wider. A secondary air outlet 251 is formed on the front side of the front panel assembly 2, so that the secondary air outlet 251 is provided between the two main air outlets 13. This allows the air blown out by the secondary air outlet 251 to be closer to the front center of the air conditioner, thereby effectively regulating the temperature in front of the air conditioner, enhancing the uniformity of the indoor temperature, and thus improving the user experience.

[0067] Reference Figures 1-3 According to some embodiments of the present invention, the front panel assembly 2 and the main housing assembly 1 are detachably connected, which facilitates the maintenance or replacement of the front panel assembly 2 or the main housing assembly 1.

[0068] For example, one of the front panel assembly 2 and the main housing assembly 1 may be provided with a buckle, and the other of the front panel assembly 2 and the main housing assembly 1 may be provided with a slot, which can realize the detachable connection between the front panel assembly 2 and the main housing assembly 1, and can also make the connection between the front panel assembly 2 and the main housing assembly 1 simple and have strong stability; or fasteners may be sequentially inserted through the front panel assembly 2 and the main housing assembly 1, which can also realize the detachable connection between the front panel assembly 2 and the main housing assembly 1.

[0069] Reference Figures 3-6 According to some embodiments of this utility model, there are multiple secondary air outlets 251, which are arranged at intervals in the left and right direction. This can increase the air outlet area of ​​the secondary air outlets 251 of the air conditioner, so that more air can be blown out from the secondary air outlets 251 and flow towards the front center of the air conditioner, thereby enhancing the temperature regulation effect on the front of the air conditioner.

[0070] In the description of this utility model, "multiple" means two or more.

[0071] Reference Figures 3-6 According to some embodiments of this utility model, there are multiple secondary air ducts 22, which are arranged at intervals in the left-right direction. The number of secondary air ducts 22 is the same as the number of secondary air outlets 251, and each secondary air duct 22 corresponds to a secondary air outlet 251. Each secondary air duct 22 connects the corresponding secondary air outlet 251 to the main air duct. By ensuring that the number of secondary air ducts 22 is the same as the number of secondary air outlets 251, and that each secondary air duct 22 corresponds to a secondary air outlet 251, precise airflow distribution can be achieved. At least a portion of the airflow in the main air duct can be accurately delivered to the corresponding secondary air outlet 251 through each secondary air duct 22, so that each secondary air outlet 251 has a relatively independent and stable airflow blown into the room.

[0072] Reference Figures 3-6 According to some embodiments of this utility model, there are two secondary air outlets 251, which are located at the left and right ends of the front panel assembly 2, respectively. Positioning the two secondary air outlets 251 at the left and right ends of the front panel assembly 2 allows airflow to be evenly distributed from both sides of the front panel assembly 2, making the airflow from the secondary air outlets 251 closer to the front center of the air conditioner and more uniform, thus avoiding uneven airflow distribution that might result from unilateral airflow.

[0073] Reference Figures 3-6 According to some embodiments of this utility model, there are two secondary air ducts 22, located at the left and right ends of the front panel assembly 2. The secondary air duct 22 at the left end connects the corresponding secondary air outlet 251 to the main air duct, and the secondary air duct 22 at the right end connects the corresponding secondary air outlet 251 to the main air duct. The two secondary air ducts 22 are located at the left and right ends of the front panel assembly 2, respectively, and each independently connects the main air duct to the corresponding secondary air outlet 251, enabling efficient airflow transmission. This provides a direct and clear channel for airflow, allowing at least a portion of the airflow in the main air duct to flow quickly and smoothly through the secondary air duct 22 to the secondary air outlet 251, thereby improving the airflow efficiency of the secondary air outlet 251.

[0074] Reference Figures 3-6 According to some embodiments of the present invention, the secondary air duct 22 has a first sidewall 221 and a second sidewall 222 disposed opposite to each other in the left-right direction. At least one of the first sidewall 221 and the second sidewall 222 forms a guide surface 2211. The guide surface 2211 is located at the air outlet end of the secondary air duct 22 and is used to guide at least a portion of the airflow in the secondary air duct 22 toward the front of the front panel assembly 2. By providing a guide surface 2211 at the air outlet end of the secondary air duct 22, at least a portion of the airflow in the secondary air duct 22 can be guided toward the front of the front of the front panel assembly 2, so that the airflow is more concentrated and blown toward the front center of the air conditioner, avoiding the airflow from being dispersed to other unnecessary directions, thereby improving the utilization rate of the airflow and thus more effectively regulating the temperature in front of the air conditioner.

[0075] The airflow guide surface 2211 can be used to guide at least a portion of the airflow in the secondary air duct 22 toward the front of the front panel assembly 2, for example, the airflow guide surface 2211 can be used to guide a portion of the airflow in the secondary air duct 22 toward the front of the front panel assembly 2; or the airflow guide surface 2211 can be used to guide all the airflow in the secondary air duct 22 toward the front of the front panel assembly 2.

[0076] Reference Figures 3-6According to some embodiments of this utility model, in the left-right direction, the first sidewall 221 is located on the side of the second sidewall 222 away from the center of the front panel assembly 2, and the guide surface 2211 is located on the first sidewall 221. The guide surface 2211 is an arc-shaped surface that curves away from the second sidewall 222. By setting the guide surface 2211 as an arc-shaped surface, the airflow in the secondary air duct 22 can be more accurately guided to the front of the front panel assembly 2. Moreover, when the airflow passes through the arc-shaped guide surface 2211, it will gradually change its flow direction along its curvature, realizing a smooth transition from lateral flow to frontal flow in the secondary air duct 22, reducing the possibility of noise and turbulence caused by sudden changes in airflow.

[0077] Reference Figures 3-6 According to some embodiments of the present invention, the main air duct includes two main air outlet channels 12 arranged along the left and right sides. The two main air outlet channels 12 are respectively located on the left and right sides of the front panel assembly 2. The auxiliary air duct 22 located at the left end connects the main air outlet channel 12 located on the left side with the corresponding auxiliary air outlet 251, and the auxiliary air duct 22 located at the right end connects the main air outlet channel 12 located on the right side with the corresponding auxiliary air outlet 251.

[0078] Two main air outlet ducts 12 are located on the left and right sides of the front panel 24, respectively, allowing airflow to be blown out from the main air outlets 13 distributed on the left and right sides of the front panel 24. This gives the air conditioner a wide air delivery angle. A secondary air duct 22 at the left end connects the main air outlet duct 12 on the left to the corresponding secondary air outlet 251, and a secondary air duct 22 at the right end connects the main air outlet duct 12 on the right to the corresponding secondary air outlet 251. This allows the airflow in the main air outlet duct 12 on the left to flow smoothly through the secondary air duct 22 to the secondary air outlet 251 on the left, and the airflow in the main air outlet duct 12 on the right to flow smoothly through the secondary air duct 22 to the secondary air outlet 251 on the right. This achieves orderly airflow and reduces airflow resistance and the possibility of turbulence.

[0079] Reference Figures 3-6 According to some embodiments of this utility model, the main air outlet duct 12 on the left side extends inclined to the left in the direction from back to front, and the main air outlet duct 12 on the right side extends inclined to the right in the direction from back to front. The main air outlet ducts 12 on the left and right sides extend inclined in their respective directions, so that there is a certain angle between the airflow direction blown out of the main air outlet 13 and the left and right directions. This can make the air outlet angle of the main air outlet 13 wider, so that the air conditioner has a larger air outlet range and can deliver air to a larger area in front of the air conditioner.

[0080] Reference Figures 3-6According to some embodiments of the present invention, the front panel assembly 2 and the main housing assembly 1 together define two main air outlet channels 12 and two main air outlets 13. A secondary air inlet 231 is formed on the side of the front panel assembly 2 facing the main air outlet channel 12. The secondary air inlet 231 connects the corresponding main air outlet channel 12 and the secondary air duct 22. For example, the main air duct includes two main air outlet channels 12 arranged along the left and right sides. The two main air outlet channels 12 are located on the left and right sides of the front panel assembly 2, respectively. The auxiliary air inlet 231 of the main air outlet channel 12 on the left side is used to connect the main air outlet channel 12 on the left side with the auxiliary air outlet channel 22 on the left end. The auxiliary air outlet channel 22 on the left end is used to connect the auxiliary air inlet 231 of the main air outlet channel 12 on the left side with the corresponding auxiliary air outlet 251. The auxiliary air inlet 231 of the main air outlet channel 12 on the right side is used to connect the main air outlet channel 12 on the right side with the auxiliary air outlet channel 22 on the right end. The auxiliary air outlet channel 22 on the right end is used to connect the auxiliary air inlet 231 of the main air outlet channel 12 on the right side with the corresponding auxiliary air outlet 251.

[0081] A secondary air inlet 231 is formed on one side of the front panel assembly 2 facing the main air outlet duct 12. The secondary air inlet 231 connects the corresponding main air outlet duct 12 and the secondary air duct 22, so that the airflow in the main air outlet duct 12 can flow smoothly through the secondary air inlet 231 to the corresponding secondary air duct 22, and then blown to the front center of the air conditioner through the corresponding secondary air outlet 251.

[0082] Reference Figures 5-8 According to some embodiments of this utility model, a single secondary air duct 22 corresponds to a plurality of secondary air inlets 231 arranged at intervals along the vertical direction. The arrangement of multiple secondary air inlets 231 at intervals along the vertical direction can increase the air intake area of ​​the secondary air inlets 231, so that more airflow can flow into the secondary air duct 22, thereby improving the air outlet efficiency of the secondary air duct 22. It can also allow the airflow in the main air outlet duct 12 to flow into the secondary air duct 22 from the secondary air inlets 231 at different heights. In this way, when the secondary air duct 22 discharges air, the air can be delivered more evenly in the vertical direction, avoiding the situation of excessively strong or weak local airflow.

[0083] Reference Figures 7-10 According to some embodiments of the present invention, the front panel assembly 2 includes a front panel component 23 and a front air outlet frame 21. The front panel component 23 is detachably connected to the front side of the front air outlet frame 21. The front panel component 23 and the front air outlet frame 21 together define a secondary air duct 22. A secondary air inlet 231 is formed in the front air outlet frame 21, and a secondary air outlet 251 is formed in the front panel component 23. By detachably connecting the front panel component 23 to the front side of the front air outlet frame 21, it is convenient to maintain or replace the front panel component 23 or the front air outlet frame 21.

[0084] A secondary air inlet 231 is formed on the front air outlet frame 21, and a secondary air outlet 251 is formed on the front panel component 23. The front panel component 23 and the front air outlet frame 21 together define the secondary air duct 22, making the airflow smoother and reducing the resistance of the airflow during the flow process. For example, the airflow path can be: the airflow in the main air outlet duct 12 flows into the secondary air duct 22 through the secondary air inlet 231 on the front air outlet frame 21, and then blows towards the front center of the air conditioner through the secondary air outlet 251.

[0085] Reference Figures 7-10 According to some embodiments of this utility model, the left and right ends of the front panel component 23 are provided with a first buckle 232 and a second buckle 233, and the front air outlet frame 21 is provided with a first slot 211 and a second slot. The first buckle 232 is inserted downward into the first slot 211, and the second buckle 233 is inserted downward into the second slot. By engaging the first buckle 232 with the first slot 211 and the second buckle 233 with the second slot, a detachable connection between the front panel component 23 and the front air outlet frame 21 can be achieved. This also makes the connection between the front panel component 23 and the front air outlet frame 21 simple and has strong stability.

[0086] By inserting the first buckle 232 downward into the first slot 211 and the second buckle 233 downward into the second slot, the connection between the front panel component 23 and the front air outlet frame 21 can be limited in the vertical direction, reducing the possibility of relative movement between the front panel component 2 and the front air outlet frame 21 in the vertical direction.

[0087] For example, the first buckle 232 structure includes two sets of first buckles 232, which are arranged at intervals along the left and right directions of the front air outlet frame 21. Each set of buckles includes multiple first buckles 232, which are arranged at intervals along the up and down directions. The first slot 211 includes two sets of first slots 211, which are arranged at intervals along the left and right directions of the front air outlet frame 21. Each set of first slots 211 includes multiple first slots 211, which are arranged at intervals along the up and down directions. The number of first buckles 232 and first slots 211 are the same and they correspond one-to-one. The first buckle 232 is inserted downward into the first slot 211, which can further enhance the connection strength between the front panel assembly 2 and the front air outlet frame 21, and can make the force on the front panel assembly 2 and the front air outlet frame 21 more uniform in the up and down directions.

[0088] The second buckle 233 structure includes two sets of second buckles 233, which are arranged at intervals along the left and right directions of the front air outlet frame 21.

Each set of second slots includes multiple second slots, which are arranged at intervals along the up and down directions. The number of second buckles 233 and second slots are the same and they correspond one-to-one. The second buckles 233 are inserted downward into the second slots, which can further enhance the connection strength between the front panel assembly 2 and the front air outlet frame 21, and can make the force on the front panel assembly 2 and the front air outlet frame 21 more even in the up and down directions.

[0089] Reference Figures 7-10 According to some embodiments of this utility model, the first buckle 232 and the second buckle 233 are arranged at intervals in the left-right direction. The second buckle 233, located at the same end of the front panel component 23 in the left-right direction, is on the side of the first buckle 232 closer to the outer edge of the front panel component 23. The two buckles are arranged at intervals in the left-right direction, so that the front panel component 2 and the front air outlet frame 21 have at least two fixing points in the left-right direction. The second buckle 233 is located on the side of the first buckle 232 closer to the outer edge of the front panel component 23, which can make the force on the front panel component 23 more uniform in the left-right direction. For example, the first buckle 232 can bear the force in the middle area of ​​the front panel component 23 in the left-right direction, and the second buckle 233 can share the force in the outer edge of the front panel component 23. This makes the force on each part of the entire front panel component 23 more uniform when subjected to force, reducing the possibility of deformation or damage caused by excessive local force.

[0090] Reference Figure 10 and Figure 1 According to some embodiments of the present invention, the left and right ends of the front panel component 23 are formed with limiting grooves 234, and the left and right ends of the front air outlet frame 21 are formed with limiting protrusions 213. The limiting protrusions 213 are inserted forward into the limiting grooves 234. The limiting protrusions 213 can enhance the structural strength of the front air outlet frame 21 to a certain extent. By inserting the limiting protrusions 213 forward into the limiting grooves 234, the connection between the front panel component 23 and the front air outlet frame 21 can be limited in the front-rear direction, reducing the possibility of relative movement between the front panel component 2 and the front air outlet frame 21 in the front-rear direction.

[0091] Reference Figure 7 and Figure 8According to some embodiments of this utility model, a fixing post 214 is provided on the upper part of the front air outlet frame 21, and a positioning hole 235 is formed on the upper part of the front panel component 23. Fasteners are passed through the positioning hole 235 and the fixing post 214 vertically. The fixing post 214 and the positioning hole 235 can play a positioning role in the assembly between the front panel component 23 and the front air outlet frame 21, so that the assembly position between the front panel component 23 and the front air outlet frame 21 is accurate. By using fasteners passing through the positioning hole 235 and the fixing post 214, a detachable connection between the front panel component 23 and the front air outlet frame 21 can be realized, and the connection between the front panel component 23 and the front air outlet frame 21 can be simplified and has strong stability.

[0092] By using fasteners that pass through the positioning holes 235 and the fixing posts 214 vertically, the connection between the front panel component 23 and the front air outlet frame 21 can be limited in the vertical direction, reducing the possibility of relative movement between the front panel component 2 and the front air outlet frame 21 in the vertical direction.

[0093] Reference Figures 9-12 According to some embodiments of this utility model, the front panel component 23 includes a front panel 24 and a panel bracket 25. The front panel 24 is fixed to the front side of the panel bracket 25. The panel bracket 25 and the front air outlet frame 21 together define the secondary air duct 22.

[0094] The panel bracket 25 and the front air outlet frame 21 together define the secondary air duct 22. Two secondary air outlets 251 are located on the panel bracket 25 and on the left and right sides of the front panel 24, respectively, which makes the airflow smoother and reduces the resistance during the airflow process. For example, the airflow path can be: the airflow in the main air duct flows into the secondary air duct 22 through the secondary air inlet 231 on the front air outlet frame 21, and then blows towards the front center of the air conditioner through the secondary air outlets 251.

The third buckle 215 is inserted downward into the third slot. By engaging the third buckle 215 with the third slot, a detachable connection between the front air outlet frame 21 and the main housing assembly 1 can be achieved. This also simplifies the connection between the front air outlet frame 21 and the main housing assembly 1 and provides strong stability. The downward insertion of the third buckle 215 into the third slot limits the connection between the front air outlet frame 21 and the main housing assembly 1 in the vertical direction, reducing the possibility of relative movement between them.

When the switch door 14 is in the position of closing the main air outlet 13, at least a portion of the protective pads 237 are located between the switch door 14 and the reinforcing flanges 236. The reinforced flange 236 can enhance the structural strength of the front panel component 23 to a certain extent. The reinforced flange 236 is equipped with a protective pad 237. When the door 14 is in the position of closing the main air outlet 13, the protective pad 237 can play a buffering role, reducing the impact force between the door 14 and the front panel component 23. This helps to reduce the noise generated by the collision between the door 14 and the front panel component 23 when the door 14 is closed. It can also reduce the friction and wear between the door 14 and the front panel component 23 caused by frequent opening and closing of the door 14, which helps to extend the service life of the door 14 and the front panel component 23.

[0097] Additionally, when the switch door 14 is in the position where the main air outlet 13 is closed, the protective pad 237 can fill at least a portion of the gap between the switch door 14 and the front panel component 23, thereby sealing the gap between the switch door 14 and the front panel component 23 and reducing or preventing the possibility of airflow leakage from the gap between the front panel component 23 and the switch door 14.
