[0028] The following is a reference appendix. Figure 1 and attached Figure 2 An air conditioner 100 according to some embodiments of the present invention is described.

[0029] According to the embodiment of the present utility model, the air conditioner 100, such as Figure 1 As shown, the air conditioner 100 includes: a housing 1, a fan assembly 3, and a heat exchanger 2. The length direction of the housing 1 is vertical. One of the left wall surface 11 and the right wall surface 12 of the housing 1 is a first side wall 1a, and the other is a second side wall 1b. The fan assembly 3 is disposed inside the housing 1 and includes a cross-flow impeller 31 with its axis vertically oriented. The heat exchanger 2 is disposed inside the housing 1 and is located on the side of the cross-flow impeller 31 near the second side wall 1b. The heat exchanger 2 includes a rear extension 21 and a front extension 22. The front extension 22 is located in front of the rear extension 21. The rear extension 21 extends from the position of the heat exchanger 2 near the second side wall 1b toward the rear of the cross-flow impeller 31, and the front extension 22 extends from the position of the heat exchanger 2 near the second side wall 1b toward the front of the cross-flow impeller 31.

[0030] When the left wall 11 of the shell 1 is the first side wall 1a, and the right wall 12 of the shell 1 is the second side wall 1b, the cross-flow impeller 31 is positioned to the left of the heat exchanger 2, and both the front extension 22 and the rear extension 21 of the heat exchanger 2 extend from right to left; Figure 1 As shown, when the right wall 12 of the shell 1 is the first side wall 1a and the left wall 11 of the shell 1 is the second side wall 1b, the cross-flow impeller 31 is set to the right relative to the heat exchanger 2, and the front extension 22 and the rear extension 21 of the heat exchanger 2 both extend from left to right.

[0031] The cross-flow fan 31 provides airflow, drawing air in from the inlet 15 and expelling it from the outlet 16. The cross-flow fan 31 is located between the front end portion 22a and the rear end portion 21a in the front-to-back direction. The front extension 22 of the heat exchanger 2 gradually extends forward of the cross-flow fan 31, and the rear extension 21 gradually extends backward of the cross-flow fan 31. Specifically, the rear extension 21 of the heat exchanger 2 refers to the portion of the heat exchanger 2 near the second sidewall 1b extending to the rear of the cross-flow fan 31, and the front extension 22 of the heat exchanger 2 refers to the portion of the heat exchanger 2 near the second sidewall 1b extending to the front of the cross-flow fan 31. For example, as... Figure 1As shown, the heat exchanger 2 can be a single piece, with a curved shape. A portion of the heat exchanger 2 extends along the second sidewall 1b toward the first sidewall 1a towards the front of the cross-flow impeller 31, and another portion extends along the second sidewall 1b toward the first sidewall 1a towards the rear of the cross-flow impeller 31. Alternatively, the heat exchanger 2 can be a split structure, with a front extension 22 and a rear extension 21 spaced apart. The front extension 22 extends along the second sidewall 1b toward the first sidewall 1a towards the front of the cross-flow impeller 31, and the rear extension 21 extends along the second sidewall 1b toward the first sidewall 1a towards the rear of the cross-flow impeller 31.

[0032] With the heat exchanger 2 arranged in this way, the heat exchange area is large and the heat exchange efficiency is high; and the cross-flow fan 31 is located on the opening side of the heat exchanger 2 and arranged on the left and right sides of the heat exchanger 2, which makes full use of the space in the left and right directions and helps to reduce the size of the shell 1 in the front and back directions.

[0033] According to the embodiment of the present utility model, the air conditioner 100 has a large heat exchange area and high heat exchange efficiency due to the arrangement of the heat exchanger 2; and the cross-flow fan 31 is located on the opening side of the heat exchanger 2 and arranged on the left and right sides with the heat exchanger 2, which makes full use of the space in the left and right directions and helps to reduce the size of the shell 1 in the front and back directions.

[0034] In some embodiments of this utility model, such as Figure 1 As shown, the end of the front extension 22 that is away from the second sidewall 1b is the front end portion 22a, which is located on the side of the left-right dividing plane S of the cross-flow impeller 31 that is close to the first sidewall 1a in the left-right direction.

[0035] The cross-flow fan 31 has a left-right dividing plane S that passes through its axis and extends in the front-back direction. The heat exchanger 2 is positioned relative to the cross-flow fan 31 near the second sidewall 1b, while the front extension 22 extends towards the first sidewall 1a, with its front end 22a positioned relative to the left-right dividing plane S of the cross-flow fan 31 near the first sidewall 1a. Thus, the front extension 22 extends in the left-right direction, covering at least half of the cross-flow fan 31. The relatively long length of the front extension 22 results in a larger heat exchange area and higher heat exchange efficiency. When airflow enters the air conditioner 100 from the front, the airflow flows towards the front extension 22 and then towards the cross-flow fan 31. The relatively long length of the front extension 22 in the left-right direction further enhances heat exchange efficiency.

[0036] In some embodiments of this utility model, such as Figure 1As shown, the end of the rear extension 21 that is away from the second sidewall 1b is the rear end 21a. On the cross-section of the cross-flow impeller 31, the line M connecting the front end 22a and the rear end 21a passes through the cross-flow impeller 31 to divide the cross-flow impeller 31 into two parts, and the ratio of the areas of the two parts is 3 / 7 to 7 / 3.

[0037] The line M connecting the front end 22a and the rear end 21a passes through the cross-flow impeller 31. The line M connecting the front end 22a and the rear end 21a divides the cross-flow impeller 31 into two parts. The two parts are separated by the line M connecting the front end 22a and the rear end 21a. One part is set relatively close to the heat exchanger 2, and the other part is set relatively far away from the heat exchanger 2. The area ratio of these two parts is 3 / 7 to 7 / 3.

[0038] It is understandable that the rear extension 21 of heat exchanger 2 extends to the rear of the cross-flow fan 31, and the front extension 22 of heat exchanger 2 extends to the front of the cross-flow fan 31. When the area ratio of the two parts is small, the space occupied by heat exchanger 2 in the front-rear direction of cross-flow fan 31 is smaller, which facilitates the arrangement of heat exchanger 2 and cross-flow fan 31 and helps to reduce the size of air conditioner 100 in the front-rear direction. When the area ratio is large, it means that the extension length of the front extension 22 and / or the rear extension 21 of heat exchanger 2 in the left-right direction is longer, the heat exchange area is increased, and the heat exchange efficiency is improved. The extension length of the front extension 22 and / or the rear extension 21 of heat exchanger 2 can be changed according to actual use needs.

[0039] By limiting the area ratio of these two parts to 3 / 7 to 7 / 3, the area ratio of these two parts will not be too small, so that the length of the front extension 22 and / or the rear extension 21 in the left and right directions is sufficient for heat exchange; and the area ratio of these two parts will not be too large, so that the front extension 22 and the rear extension 21 will not be overextended in the left and right directions, resulting in wasted space, thereby helping to reduce the size of the air conditioner 100 in the front and back directions.

[0040] Alternatively, the area ratio of the two parts can be 4 / 7, 4 / 6, 5 / 5, 5 / 4, 6 / 4, etc.

[0041] In some embodiments of this utility model, such as Figure 1 As shown, the end of the front extension 22 away from the second sidewall 1b is the front end portion 22a, which is located on the side of the left and right dividing plane N of the front wall surface 13 of the housing 1, close to the first sidewall 1a.

[0042] The heat exchanger 2 is positioned close to the second sidewall 1b relative to the cross-flow fan 31, and the front extension 22 extends through the left-right dividing plane N of the front wall surface 13. The left-right dividing plane N of the front wall surface 13 refers to the plane that passes through the center line of the front wall surface 13 in the left-right direction and extends in the front-back direction. Therefore, the front extension 22 has a relatively long extension length in the left-right direction, resulting in a larger heat exchange area and higher heat exchange efficiency. When airflow flows into the air conditioner 100 from the front, the airflow flows through the front extension 22 and then towards the cross-flow fan 31. The relatively long extension length of the front extension 22 in the left-right direction further enhances the heat exchange efficiency.

[0043] In some embodiments of this utility model, such as Figure 1 As shown, the angle D between the extension line G1 of the front extension 22 in the direction from the second sidewall 1b to the first sidewall 1a and the reference line G2 extending in the left-right direction is 0°-45°; and / or, the distance L1 between the front extension 22 and the front wall surface 13 of the housing 1 is 20-80mm.

[0044] When the angle D between the extension line G1 of the front extension 22 in the direction from the second sidewall 1b to the first sidewall 1a and the reference line G2 extending in the left-right direction is too large, the space occupied by the front extension 22 in the front-rear direction will be too large, which will lead to an increase in the front-rear dimension of the housing 1. Therefore, setting the angle D between the extension line G1 of the front extension 22 in the direction from the second sidewall 1b to the first sidewall 1a and the reference line G2 extending in the left-right direction to 0°-45° is optimal, which is beneficial to reducing the front-rear dimension of the housing 1.

[0045] Optionally, the angle D between the extension line G1 of the front extension 22 in the direction from the second side wall 1b to the first side wall 1a and the reference line G2 extending in the left-right direction can be 10°, 15°, 25°, 30°, 42°, etc.

[0046] The distance L1 between the front extension 22 and the front wall surface 13 is 20-80mm. The smaller distance between the front extension 22 and the front wall surface 13 allows the heat exchanger 2 to make full use of the internal space of the shell 1, which is beneficial to increasing the heat exchange area of ​​the heat exchanger 2 and improving the heat exchange efficiency. However, if the distance between the front extension 22 and the front wall surface 13 is too small, the heat exchanger 2 is prone to thermal influence on the front wall surface 13, and the heat exchanger 2 is easily damaged when the air conditioner 100 is subjected to vibration.

[0047] Therefore, setting the distance L1 between the front extension 22 and the front wall 13 to 20mm-80mm is optimal. This allows for full utilization of the internal space of the housing 1, a larger heat exchange area for the heat exchanger 2, and a reduction in the thermal impact on the front wall 13.

[0048] Optionally, the distance L1 between the front extension 22 and the front wall surface 13 can be 25mm, 30mm, 40mm, 50mm, 70mm, etc.

[0049] The angle D between the extension line G1 of the front extension 22 extending from the second sidewall 1b to the first sidewall 1a and the reference line G2 extending in the left-right direction is 0°-45°, and the distance L1 between the front extension 22 and the front wall surface 13 is 20-80mm. This allows the front extension 22 to fully utilize the space within the housing 1, increasing the heat exchange area of ​​the heat exchanger 2 and improving heat exchange efficiency.

[0050] In some embodiments of this utility model, such as Figure 2 As shown, the air inlet 15 of the air conditioner 100 includes a front air inlet 153 formed on the front wall surface 13 of the housing 1. The front air inlet 153 is disposed in the left-right direction relative to the first side wall 1a and close to the second side wall 1b.

[0051] An air inlet 153 is provided on the front wall surface 13, and the distance between the air inlet 153 and the second side wall 1b is smaller than the distance between the air inlet 153 and the first side wall 1a. The air inlet 153 is relatively close to the second side wall 1b.

[0052] By placing the front air inlet 153 close to the second side wall 1b, the clustering between the front air inlet 153 and the heat exchanger 2 can be shortened, thereby shortening the airflow path and improving heat exchange efficiency.

[0053] In some embodiments of this utility model, the front extension 22 has a relatively long extension length in the left and right direction. By providing a front air inlet 153 on the front wall surface 13, the airflow flows to the front extension 22 and then to the cross-flow fan 31. The front extension 22 has a relatively long extension length in the left and right direction, which allows the airflow to fully exchange heat with the front extension 22, which is beneficial to improving the heat exchange efficiency.

[0054] In some embodiments of this utility model, such as Figure 2 As shown, the front wall surface 13 also has an air outlet 16, which is located on the side of the front air inlet 153 near the first side wall 1a; the dimension of the air outlet 16 in the left-right direction is less than or equal to the dimension of the front air inlet 153 in the left-right direction; and / or the ratio of the dimension of the front air inlet 153 in the left-right direction to the dimension of the air outlet 16 in the left-right direction is 0.8-2; and / or the ratio of the dimension L2 of the front air inlet 153 in the left-right direction to the dimension L3 of the front wall surface 13 in the left-right direction is 0.4-0.6.

[0055] The front wall 13 also has an air outlet 16. The front air inlet 153 is located near the second side wall 1b. The air outlet 16 is located on the side of the front air inlet 153 that is close to the first side wall 1a. The air outlet 16 is located relatively far away from the front air inlet 153, which can reduce the situation where the air flows directly back to the front air inlet 153 and improve the air outlet reliability of the air conditioner 100.

[0056] The size of the air outlet 16 in the left-right direction is less than or equal to the size of the front air outlet 153 in the left-right direction. The larger size of the front air outlet 153 can increase the air intake of the air conditioner.

[0057] The ratio of the left-right dimension of the front air vent 153 to the left-right dimension of the air outlet 16 is 0.8-2. The left-right dimension of the front air vent 153 can be larger than the left-right dimension of the air outlet 16, thus increasing the air intake volume of the air conditioner. Optionally, the ratio of the left-right dimension of the front air vent 153 to the left-right dimension of the air outlet 16 can be 1.2, 1.5, 1.6, 1.8, 1.9, etc.

[0058] The size of the front air vent 153 in the left-right direction can also be less than or equal to the size of the air outlet 16 in the left-right direction, thereby increasing the size of the air outlet 16 and improving airflow smoothness. Optionally, the ratio of the size of the front air vent 153 in the left-right direction to the size of the air outlet 16 in the left-right direction is 0.85, 0.88, 0.9, 0.95, 1, etc.

[0059] The ratio of the left-right dimension L2 of the front air vent 153 to the left-right dimension L3 of the front wall surface 13 is 0.4-0.6. The front air vent 153 has a larger dimension on the front wall surface 13, which can increase the air intake volume of the air conditioner 100. Furthermore, the front air vent 153 has a smaller dimension on the front wall surface 13, and the distance between the front air vent 153 and the air outlet 16 is sufficient to reduce the situation where the exhaust air flows directly back to the front air vent 153, thereby improving the air outlet reliability of the air conditioner 100.

[0060] Optionally, the ratio of the dimension L2 of the front air vent 153 in the left-right direction to the dimension L3 of the front wall surface 13 in the left-right direction can be 0.45, 0.46, 0.5, 0.55, 0.58, etc.

[0061] In some embodiments of this utility model, such as Figure 2 As shown, the air conditioner 100 also includes an air inlet grille 71 and a filter 72. The air inlet grille 71 is detachably mounted on the front air inlet 153, and the filter 72 is detachably mounted inside the housing 1 and / or on the mounting bracket of the heat exchanger 2. The filter 72 is located on the side of the heat exchanger 2 away from the cross-flow impeller 31, and the filter 72 is adapted to be installed and removed through the front air inlet 153.

[0062] The air intake grille 71 is installed in the front air vent 153, which can prevent users from directly putting their hands into the front air vent 153, and can improve the overall appearance of the front wall 13 while reducing the impact on the air intake of the air conditioner 100.

[0063] A filter screen 72 is installed inside the housing 1. The filter screen 72 is detachably installed inside the housing 1 and / or on the mounting bracket of the heat exchanger 2. The filter screen 72 is located on the side of the heat exchanger 2 away from the cross-flow impeller 31. The airflow flowing in from the inlet 153 will be filtered by the filter screen 72 before flowing to the heat exchanger 2, which can reduce the contact of dust and other pollutants with the heat exchanger 2 and improve the working reliability of the heat exchanger 2.

[0064] The filter 72 is suitable for installation and removal through the front air inlet 153. The front air inlet 153 is relatively large, which facilitates the installation and removal of the filter 72.

[0065] In some embodiments of the present invention, the rear wall surface 14 of the air conditioner 100 includes a rear wall portion 141, which is connected to the second side wall 1b and located obliquely behind the second side wall 1b. At least one of the second side wall 1b and the rear wall portion 141 is provided with an air inlet 15 of the air conditioner 100.

[0066] An air inlet 15 is provided on the second side wall 1b, or an air inlet 15 is provided on the rear wall 141. The housing 1 has a larger area for the air inlet 17, which can increase the air intake.

[0067] When both the second side wall 1b and the rear wall 141 are provided with air inlets 15, the air conditioner 100 can draw air from two directions, resulting in a larger air intake area, higher air intake efficiency, and increased air volume.

[0068] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the rear wall portion 141 extends obliquely rearward from the second side wall 1b toward the direction close to the first side wall 1a. That is, the rear wall portion 141 extends obliquely from front to back relative to the second side wall 1b in the direction from the second side wall 1b to the first side wall 1a, and the air inlet 15 of the air conditioner 100 includes a rear air inlet 152 formed on the rear wall portion 141.

[0069] The rear wall portion 141 extends obliquely from front to back in the direction from the second side wall 1b to the first side wall 1a. In this way, when the rear side of the air conditioner 100 is placed close to a wall or other structure, a space is created between the rear wall portion 141 and these structures, allowing airflow. A rear air inlet 152 is provided on the rear wall portion 141 to increase the air intake volume of the air conditioner 100.

[0070] In some embodiments of this utility model, such as Figure 2As shown, the included angle C between the rear wall portion 141 and the second side wall 1b is 115°-176°; or, as... Figure 1 As shown, the angle B between the rear wall portion 141 and the baseline G2 extending in the left-right direction is 10°-65°.

[0071] The angle C between the rear wall portion 141 and the second side wall 1b is an obtuse angle. The second side wall 1b can extend in the front-rear direction or in a direction with a certain angle of inclination to the front-rear direction. The obtuse angle C between the rear wall portion 141 and the second side wall 1b allows for a smooth transition between them. A larger angle C between the rear wall portion 141 and the second side wall 1b increases the internal space of the housing 1, while a smaller angle C increases the external space of the rear wall portion 141, which is beneficial for airflow. The angle C between the rear wall portion 141 and the second side wall 1b can be selected according to actual needs.

[0072] Optionally, the included angle C between the rear wall portion 141 and the second side wall 1b can be 120°, 145°, 150°, 160°, 170°, etc.

[0073] Alternatively, the angle B between the rear wall portion 141 and the reference line G2 extending in the left-right direction is 10°-65°. When the angle B between the rear wall portion 141 and the reference line G2 extending in the left-right direction is large, the external space of the rear wall portion 141 can be increased, which is beneficial to airflow. When the angle B between the rear wall portion 141 and the reference line G2 extending in the left-right direction is small, the internal space of the housing 1 can be increased. The angle C between the rear wall portion 141 and the second side wall 1b can be selected according to actual needs.

[0074] Optionally, the angle B between the rear wall portion 141 and the reference line G2 extending in the left-right direction can be 20°, 45°, 30°, 50°, 60°, etc.

[0075] In some embodiments of this utility model, such as Figure 2 As shown, the front wall surface 13 of the housing 1 has an air outlet 16, which is located in the left-right direction relative to the second side wall 1b and close to the first side wall 1a. The air conditioner 100 includes an air guide device 73 located at the air outlet 16.

[0076] The front wall 13 of the housing 1 has an air outlet 16, which can increase the air supply range of the air conditioner 100 in the left and right directions. The air outlet 16 is set closer to the first side wall 1a than the second side wall 1b in the left and right directions. The air outlet 16 is set further away from the heat exchanger 2 than the cross-flow fan 31 in the left and right directions, thereby shortening the distance from the cross-flow fan 31 to the air outlet 16, shortening the airflow path, and improving the air supply efficiency.

[0077] The air conditioner 100 includes an air guide device 73 disposed at the air outlet 16. The air guide device 73 can guide the airflow, thereby increasing the airflow coverage of the air conditioner 100 and improving the air delivery effect.

[0078] In some embodiments of this utility model, such as Figure 2 As shown, the fan component 3 also includes a cross-flow volute 32, which includes a first air duct wall 321 and a second air duct wall 322. An air duct 33 is formed between the first air duct wall 321 and the second air duct wall 322. The cross-flow impeller 31 is located at the entrance of the air duct 33. The first air duct wall 321 and the second air duct wall 322 extend forward from the periphery of the cross-flow impeller 31 to the front wall surface 13, and extend to the left and right edges of the air outlet 16, respectively.

[0079] A duct 33 is formed between the first duct wall 321 and the second duct wall 322. A cross-flow fan 31 is located at the entrance of the duct 33. The cross-flow fan 31 drives the heat-exchanged airflow from the entrance of the duct 33 to the outlet of the duct 33. The outlet of the duct 33 extends to the air outlet 16 on the front wall surface 13, and the airflow flows out from the air outlet 16.

[0080] The first air duct wall 321 and the second air duct wall 322 define the air outlet duct. The first air duct wall 321 and the second air duct wall 322 extend forward from the periphery of the cross-flow impeller 31 to the front wall surface 13, and extend to the left and right edges of the air outlet 16, respectively. The airflow can flow stably from the cross-flow impeller 31 to the air outlet 16 along the air duct. The first air duct wall 321 and the second air duct wall 322 have a good guiding effect on the airflow, which can reduce the generation of turbulence and improve the flow stability of the airflow.

[0081] In some embodiments of this utility model, such as Figure 2 As shown, there is a receiving space 19 between the cross-flow volute 32 and the rear wall surface 14 of the air conditioner 100, and the air conditioner 100 includes pipes and / or wires disposed in the receiving space 19.

[0082] In some embodiments of this utility model, an air conditioner 100 has a receiving space 19 formed between the cross-flow volute 32 and the rear wall surface 14 of the air conditioner 100. The receiving space 19 is used to receive pipes and / or wires, thereby reducing the occupation of the front space of the cross-flow impeller 31 by the pipes and / or wires of the air conditioner 100, thereby reducing the impact on the arrangement of the cross-flow volute 32, which is beneficial to improving the air outlet stability of the air conditioner 100.

[0083] In some embodiments of this utility model, the air inlet 15 of the air conditioner 100 includes a front air inlet 153 formed on the front wall surface 13 of the housing 1. By arranging the pipes and / or wires of the air conditioner 100 within the accommodating space 19, the occupancy of the front space of the cross-flow fan 31 can be reduced, thereby reducing the impact on the front air intake and improving the air intake volume of the air conditioner 100.

[0084] In some embodiments of this utility model, such as Figure 2 As shown, the end of the rear extension 21 that is away from the second sidewall 1b is the rear end portion 21a. The rear end portion 21a is positioned rearward relative to the rear end of the flow-through volute 32 or flush with the rear end of the flow-through volute 32 in the front-back direction.

[0085] The rear end of the cross-flow volute 32 is provided with a receiving space 19, and the rear end 21a of the rear extension 21 can be arranged rearward relative to the rear end of the cross-flow volute 32. The rear end of the cross-flow volute 32 has space for the rear extension 21 to be arranged, thereby increasing the heat exchange area of ​​the heat exchanger 2 without increasing the front-to-back dimension of the housing 1.

[0086] Alternatively, the rear end 21a can be flush with the rear end of the cross-flow volute 32, and the rear side of the rear end 21a can also provide space for the arrangement of pipes and / or wires of the air conditioner 100, which facilitates the arrangement of the internal structure of the housing 1.

[0087] In some embodiments of this utility model, such as Figure 2 As shown, the air conditioner 100 is suitable for installation within the home furnishing component 200. The home furnishing component 200 forms a receiving space for accommodating the air conditioner 100, thereby enhancing the overall integrity of the air conditioner 100 and the home furnishing component 200.

[0088] In some embodiments of the present invention, the first sidewall 1a and / or the second sidewall 1b are adapted to fit against the furniture piece 200, and the front wall surface 13 of the air conditioner 100 is adapted to be flush with the surface of the furniture piece 200.

[0089] The home furnishing component 200 has a receiving space for accommodating the air conditioner 100. The first sidewall 1a and / or the second sidewall 1b of the air conditioner 100 are adapted to fit against the home furnishing component 200, and the front wall surface 13 of the air conditioner 100 matches the surface of the home furnishing component 200. This allows the air conditioner 100 to be installed in a concealed manner, improving the overall integrity of the air conditioner 100 and the home furnishing component 200.

[0090] Since the first sidewall 1a and / or the second sidewall 1b are adapted to fit against the furniture component 200, in some embodiments of this utility model, neither air inlets 15 nor air outlets 16 are provided on the first sidewall 1a and the second sidewall 1b. This effectively prevents airflow from blowing into the furniture component 200, protecting the safety and integrity of the items inside the furniture component 200, reducing the risk of damage to the furniture component 200 and deterioration of items caused by wind damage, and extending the service life of the furniture component 200 and the items stored inside. At the same time, it also avoids airflow turbulence caused by airflow entering the furniture component 200 and then reflecting back into the indoor space, improving the stability and orderliness of indoor air circulation, and further enhancing the comfort and stability of the overall indoor temperature environment.

[0091] Since the air conditioner 100 is suitable for installation inside the home furnishing 200, and the front wall surface 13 of the air conditioner 100 is suitable for being flush with the surface of the home furnishing 200, in some embodiments of this utility model, the air inlet 15 of the air conditioner 100 is located on the front wall surface 13, and the air outlet 16 is also located on the front wall surface 13. The air inlet and outlet of the air conditioner 100 will not be blocked, which is beneficial to the air inlet and outlet of the air conditioner 100.

[0092] The following is a reference appendix. Figure 3 -Appendix Figure 8 Air conditioner 100 according to other embodiments of the present invention.

[0093] like Figure 3 and Figure 4 As shown, the air conditioner 100 includes a housing 1 and a heat exchanger 2. The length direction of the housing 1 is vertical. One of the left wall surface 11 and the right wall surface 12 of the housing 1 is a first side wall 1a, and the other is a second side wall 1b. The air inlet 15 of the air conditioner 100 includes a rear air inlet 152 formed on the rear wall surface 14 of the housing 1 and a side air inlet 151 formed on the second side wall 1b. The rear air inlet 152 is disposed in the left-right direction relative to the first side wall 1a and close to the second side wall 1b. The heat exchanger 2 is disposed inside the housing 1 and includes a rear extension 21 that extends gradually from the second side wall 1b to the first side wall 1a toward the rear wall surface 14, and a front extension 22 that extends gradually from the second side wall 1b to the first side wall 1a toward the front wall surface 13.

[0094] The rear extension 21 of the heat exchanger 2 extends from the second side wall 1b toward the first side wall 1a toward the rear wall surface 14, and the rear extension 21 can exchange heat with the airflow flowing into the side air inlet 151 and the rear air inlet 152; the front extension 22 of the heat exchanger 2 extends from the second side wall 1b toward the first side wall 1a toward the front wall surface 13, and the front extension 22 can exchange heat with the airflow flowing into the side air inlet 151. The airflow entering the air conditioner 100 from the multiple air inlets 15 can quickly exchange heat with the heat exchanger 2, which can improve the heat exchange efficiency of the air conditioner 100.

[0095] For example, the air inlet 15 further includes a front air inlet 153 formed on the front wall surface 13 of the housing 1. For instance, the front air inlet 153 is disposed in the left-right direction relative to the first side wall 1a and close to the second side wall 1b. In this case, the air conditioner 100 includes a front air inlet 153, a rear air inlet 152, and a side air inlet 151, allowing air to enter from three directions, thus increasing the air intake volume. Optionally, as... Figure 4 As shown, the left wall 11 of the housing 1 can be the second side wall 1b, and the right wall 12 can be the first side wall 1a. The air conditioner 100 can be introduced through the left, rear and front sides. The dotted lines with arrows in the figure indicate the airflow direction. Alternatively, the right wall 12 of the housing 1 can be the second side wall 1b, and the left wall 11 can be the first side wall 1a. The air conditioner 100 can be introduced through the right, rear and front sides.

[0096] Heat exchanger 2 is disposed inside housing 1. Heat exchanger 2 is used to exchange heat with the airflow flowing in from air inlet 15. Air conditioner 100 delivers heat-exchanged airflow into the room to regulate the indoor temperature. The rear extension 21 of heat exchanger 2 extends from the second side wall 1b toward the first side wall 1a toward the rear wall surface 14. The rear extension 21 can exchange heat with the airflow flowing in from the side air inlet 151 and the rear air inlet 152. The front extension 22 of heat exchanger 2 extends from the second side wall 1b toward the first side wall 1a toward the front wall surface 13. The front extension 22 can exchange heat with the airflow flowing in from the side air inlet 151 and the front air inlet 153. Airflow entering air conditioner 100 from multiple air inlets 15 can quickly exchange heat with heat exchanger 2, which can improve the heat exchange efficiency of air conditioner 100.

[0097] According to the embodiment of the present utility model, the air conditioner 100 has a heat exchanger 2 arranged corresponding to the position of the air inlet 15 on the housing 1. The heat exchanger 2 has a rear extension 21 extending rearward along the side and a front extension 22 extending forward along the side. The heat exchanger 2 has a large heat exchange area, and the airflow entering the air conditioner 100 from the multiple air inlets 15 can quickly exchange heat with the heat exchanger 2, which can improve the heat exchange efficiency of the air conditioner 100 for airflow.

[0098] In some embodiments of this utility model, such as Figure 5As shown, the end of the rear extension 21 that is away from the second sidewall 1b is the rear end 21a, and the end of the front extension 22 that is away from the second sidewall 1b is the front end 22a. The housing 1 is also provided with a fan component 3. The fan component 3 includes a vertically oriented cross-flow impeller 31. The cross-flow impeller 31 is located between the front end 22a and the rear end 21a in the front-to-back direction, and in the left-to-right direction, a portion of the cross-flow impeller 31 is located on the side of the line M connecting the front end 22a and the rear end 21a that is closer to the second sidewall 1b.

[0099] The cross-flow fan 31 provides airflow, drawing air in from the outlet 16 and expelling it from the outlet 16. The cross-flow fan 31 is located between the front end 22a and the rear end 21a in the front-rear direction. The rear extension 21 of the heat exchanger 2 extends to the rear of the cross-flow fan 31, and the front extension 22 of the heat exchanger 2 extends to the front of the cross-flow fan 31. The line M connecting the front end 22a and the rear end 21a passes through the cross-flow fan 31. The rear extension 21 and / or the front extension 22 of the heat exchanger 2 have a large extension dimension in the left-right direction, resulting in a large heat exchange area for the heat exchanger 2 and improved heat exchange efficiency for the airflow.

[0100] In some embodiments of this utility model, such as Figure 5 As shown, the axis of the cross-flow impeller 31 in the left-right direction is located on the side of the line M connecting the front end 22a and the rear end 21a, close to the first sidewall 1a.

[0101] The line M connecting the front end 22a and the rear end 21a passes through the cross-flow impeller 31, but the extension dimensions of the rear extension 21 and the front extension 22 of the heat exchanger 2 in the left-right direction will not exceed the axis of the cross-flow impeller 31. The side of the axis of the cross-flow impeller 31 closest to the first sidewall 1a is the airflow outlet side. Therefore, the extension dimensions of the rear extension 21 and the front extension 22 of the heat exchanger 2 in the left-right direction only need not exceed the axis of the cross-flow impeller 31. While meeting the airflow heat exchange requirements, it can also reduce the superposition of the dimensions of the heat exchanger 2 and the cross-flow impeller 31 in the front-back direction, save manufacturing costs, and help save space in the front-back direction, thus reducing the volume of the air conditioner 100.

[0102] In some embodiments of this utility model, such as Figure 4 As shown, the included angle A between the rear extension 21 and the front extension 22 is 25°-60°.

[0103] When the angle between the rear extension and the front extension is too small, the size of the heat exchanger in the front-to-back direction is too small, the air-facing heat exchange area of ​​the heat exchanger is reduced, and the heat exchange efficiency of the heat exchanger is low. When the angle between the rear extension and the front extension is too large, the size of the heat exchanger in the front-to-back direction is too large, which increases the space occupied in the front-to-back direction, and the heat exchanger tends to be a flat plate structure extending in the front-to-back direction, which increases the air intake resistance and is not conducive to the air intake of the air conditioner.

[0104] Therefore, in some embodiments of this utility model, the included angle A between the rear extension 21 and the front extension 22 is limited to 25°-60°, which can reduce air intake resistance, improve air intake effect, increase heat exchange efficiency, and help save space in the front and rear directions, thus reducing the volume of the air conditioner 100.

[0105] In some embodiments of this utility model, such as Figure 6 As shown, an electric auxiliary heater 4 is provided between the heat exchanger 2 and the cross-flow fan 31.

[0106] When the air conditioner 100 heats the room, the electric auxiliary heater 4 and the heat exchanger 2 work together to heat the airflow, which can improve the airflow heat exchange efficiency and speed up the adjustment of the indoor temperature.

[0107] In some embodiments of this utility model, the electric auxiliary heater 4 is a PTC (Positive Temperature Coefficient) electric auxiliary heater, which consists of one or more PTC thermistors.

[0108] PTC thermistors work by decreasing their resistance as the ambient temperature drops, thus increasing their heat output. They automatically adjust their heat output based on changes in room temperature and airflow, effectively regulating the room temperature for rapid and powerful heating.

[0109] In some embodiments of this utility model, such as Figure 7 As shown, the intersection of the first sidewall 1a and the front wall 13 of the casing 1 is the air outlet corner 17, as... Figure 6 As shown, the air outlet 16 of the air conditioner 100 is formed at the air outlet corner 17. The fan component 3 also includes a cross-flow volute 32. The cross-flow impeller 31 is fitted at the inlet 32a of the cross-flow volute. The cross-flow volute 32 extends from the inlet 32a of the cross-flow volute to the outlet 32b of the cross-flow volute in a direction close to the air outlet 16.

[0110] When the air conditioner 100 is used in the corner 200, the air outlet corner 17 is arranged away from the corner 200. The air outlet 16 located in the air outlet corner 17 can generate airflow in both the side and front directions. Compared with the scheme of only front airflow or only side airflow, the air supply angle of the air conditioner 100 is larger, which can improve the air supply effect.

[0111] The cross-flow impeller 31 provides flowing airflow, and the cross-flow volute 32 smoothly guides the airflow generated by the cross-flow impeller 31 from the inlet 32a of the cross-flow volute to the outlet 32b of the cross-flow volute, thus delivering the airflow from the air conditioner 100. The cross-flow volute 32 extends from the cross-flow impeller 31 toward the air outlet 16, and the outlet 32b of the cross-flow volute is located on the side of the cross-flow impeller 31 near the first sidewall 1a. The cross-flow impeller 31 is inclined in the left-right direction along the front-back direction, which helps to save space in the front-back direction.

[0112] In some embodiments of this utility model, such as Figure 5 As shown, the dimension of the housing 1 in the front-to-back direction is the thickness of the air conditioner 100, and the dimension of the housing 1 in the left-to-right direction is the width of the air conditioner 100. The thickness of the air conditioner 100 is less than the width of the air conditioner 100.

[0113] It can save space in the front and rear directions, which helps to reduce the size of the whole machine in the front and rear directions and reduce the footprint in the front and rear directions.

[0114] It is worth noting that the length of the housing 1 in the vertical direction is less than or equal to the height of the air conditioner 100, and the width of the air conditioner 100 is less than the length of the housing 1.

[0115] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the end of the rear extension 21 that is away from the second sidewall 1b is the rear end portion 21a, which is located on the side of the rear air inlet 152 near the first sidewall 1a in the left-right direction; the end of the front extension 22 that is away from the second sidewall 1b is the front end portion 22a, which is located on the side of the front air inlet 153 near the first sidewall 1a in the left-right direction.

[0116] The rear extension 21 extends gradually from the second sidewall 1b to the first sidewall 1a toward the rear wall surface 14. The rear end 21a of the rear extension 21, which is furthest from the second sidewall 1b, is closer to the first sidewall 1a relative to the rear air inlet 152. The air intake of the rear air inlet 152 first passes through the heat exchanger 2 and then flows to the cross-flow fan 31. The front extension 22 extends gradually from the second sidewall 1b to the first sidewall 1a toward the front wall surface 13. The front end 22a of the front extension 22, which is furthest from the second sidewall 1b, is closer to the first sidewall 1a relative to the front air inlet 153. The air intake of the front air inlet 153 first passes through the heat exchanger 2 and then flows to the cross-flow fan 31.

[0117] The heat exchanger 2 increases the length of the front extension 22 and the rear extension 21 in the left and right directions to increase the heat exchange area and improve the heat exchange efficiency of the airflow.

[0118] In some embodiments of this utility model, such as Figure 8 As shown, the heat exchanger 2 includes a bend 23, and one end of the rear extension 21 near the second sidewall 1b is connected to one end of the front extension 22 near the second sidewall 1b via the bend 23.

[0119] The front extension 22 and the rear extension 21 are connected by the bend 23. The connection between the front extension 22 and the rear extension 21 is smooth, which can reduce the space occupied by the heat exchanger 2, which is beneficial to the arrangement of the heat exchanger 2, and also helps to reduce the air inlet resistance and improve the air inlet effect.

[0120] In some embodiments of this utility model, such as Figure 4 As shown, a filter element 5 is provided between the heat exchanger 2 and the second side wall 1b.

[0121] By setting the filter element 5, the incoming air from the side air inlet 151 can be filtered, improving the cleanliness of the incoming air, preventing external pollutants from entering the air conditioner 100, and improving the cleanliness and operational stability of the air conditioner 100.

[0122] In some embodiments of this utility model, such as Figure 8 As shown, the left-right distance L between heat exchanger 2 and the second sidewall 1b is greater than 16mm.

[0123] A filter element 5 is provided between the heat exchanger 2 and the second side wall 1b. When the left and right distance L between the heat exchanger 2 and the second side wall 1b is too small, the space available for the filter element 5 is small, and the arrangement of the filter element 5 is difficult.

[0124] Therefore, in some embodiments of this utility model, the left-right distance L between the heat exchanger 2 and the second side wall 1b is limited to more than 16mm, which facilitates the arrangement of the filter element 5 and also helps to reduce the air intake resistance and improve the air intake effect.

[0125] In some embodiments of this utility model, such as Figure 5 As shown, the air conditioner 100 is adapted to be located at a corner 200, which is defined by a rear wall 201 and a side wall 202. The rear wall surface 14 is disposed near the rear wall 201 relative to the front wall surface 13, and the second side wall 1b is disposed near the side wall 202 relative to the air outlet corner 17. At least a portion of at least one of the rear wall surface 14 and the front wall surface 13 is a flat plate structure, adapted to be arranged parallel to the rear wall 201.

[0126] At least a portion of the rear wall 14 is a flat plate structure, which facilitates the arrangement of the air conditioner 100 parallel to the rear wall 201, making it easier to place the air conditioner 100 and reducing the space occupied.

[0127] At least a portion of the front wall 13 is a flat plate structure, and the air conditioner 100 is arranged parallel to the rear wall 201, which can increase the air supply angle of the air conditioner 100 and improve the air supply effect.

[0128] In some embodiments of this utility model, such as Figure 4 As shown, the air conditioner 100 also includes an air guide component 6 disposed at the air outlet 16. The air guide component 6 can guide the airflow at the air outlet 16 and improve the air outlet effect of the air conditioner 100.

[0129] like Figure 4 As shown, the air guide component 6 closes the air outlet 16, and the air conditioner 100 does not blow air; or, the air conditioner 100 blows air through the micro-holes on the air guide component 6, and the air conditioner 100 achieves windless air delivery, and the air conditioner 100 delivers air to the front and right at the same time.

[0130] like Figure 5 As shown, the air guide component 6 opens the air outlet 16, and the air conditioner 100 outputs air normally. The air conditioner 100 simultaneously sends air forward and to the right, and the air delivery angle of the air conditioner 100 is relatively large.

[0131] like Figure 6 As shown, the air guide component 6 opens the air outlet 16 and directs the airflow to the right, so the air conditioner 100 mainly supplies air to the right. When the air conditioner 100 is used in a corner 200, the air conditioner 100 supplies air to the right side and sends it along the wall, which can quickly deliver it to a farther place in the room, quickly reduce the indoor temperature difference, and improve the efficiency of regulating indoor temperature.

[0132] like Figure 8 As shown, the air guide component 6 opens the air outlet 16 and directs the airflow forward, so the air conditioner 100 mainly blows air forward. When the air conditioner 100 is used in a corner 200, the air supplied by the air conditioner 100 is directly delivered to the center of the room or blown directly on the user, which can quickly regulate the user's body temperature.

[0133] In some embodiments of this utility model, the air guiding component 6 includes one or more air guiding plates. When there are multiple air guiding plates, the multiple air guiding plates are independently controlled to form different air delivery angles, which can improve the air delivery effect of the air conditioner 100.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0135] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
