[0035] 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 intended to explain this utility model, and should not be construed as limiting this utility model.

[0036] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0037] The air conditioner 100 of this utility model is described below with reference to the accompanying drawings.

[0038] According to the embodiment of the present utility model, the air conditioner 100, such as Figure 1 and Figure 2 As shown, the air conditioner 100 includes a housing 1, a fan assembly 2, and a heat exchange assembly 3. 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. At least a portion of the air inlet 15 of the air conditioner 100 is formed on the second side wall 1b and on the rear wall surface 14 of the housing 1. The fan assembly 2 is disposed inside the housing 1 and includes a vertically oriented cross-flow impeller 21 and a cross-flow volute 22. The cross-flow impeller 21 is fitted at the inlet 22a of the cross-flow volute. The heat exchange component 3 is disposed inside the housing 1 and includes a heat exchanger 31 located between the air inlet 15 and the fan component 2 in the airflow direction. The heat exchanger 31 includes a rear extension 311 that extends gradually toward the rear wall surface 14 from the second side wall 1b to the first side wall 1a. The end of the rear extension 311 away from the second side wall 1b is the rear end 311a, which extends to the inlet 22a of the cross-flow volute.

[0039] The left wall 11 of the housing 1 can be a second side wall 1b, and the right wall 12 can be a first side wall 1a, allowing the air conditioner 100 to intake air from the left and rear sides; alternatively, the right wall 12 of the housing 1 can be a second side wall 1b, and the left wall 11 can be a first side wall 1a, allowing the air conditioner 100 to intake air from the right and rear sides. The air inlet 15 is formed at least on the second side wall 1b and the rear wall 14, allowing the air conditioner 100 to intake air from at least two directions, thus increasing the air intake volume.

[0040] The cross-flow impeller 21 provides a flowing airflow, and the cross-flow volute 22 guides the airflow generated by the cross-flow impeller 21 smoothly from the inlet 22a of the cross-flow volute to the outlet 22b of the cross-flow volute, thus delivering the airflow from the air conditioner 100.

[0041] The heat exchange component 3 exchanges heat with the airflow flowing in from the air inlet 15, and the heat-exchanged airflow delivered from the air conditioner 100 can regulate the indoor temperature. In terms of airflow direction, the heat exchange component 3 is positioned close to the air inlet 15 relative to the fan component 2. Therefore, after the airflow entering the air conditioner 100 is heat-exchanged by the heat exchanger 31, it flows to the inlet 22a of the cross-flow volute under the action of the cross-flow impeller 21, and flows out from the outlet along the cross-flow volute 22.

[0042] In related technologies, a sealing plate is often installed between the heat exchanger and the fan components, so that the airflow that has undergone heat exchange in the heat exchanger flows directly to the cross-flow volute, preventing the airflow after heat exchange from escaping from the air conditioner and reducing air volume and heat loss.

[0043] In this embodiment of the invention, the rear extension 311 of the heat exchanger 31 extends directly to the inlet 22a of the cross-flow volute. The rear end 311a of the heat exchanger 31 extends directly to the inlet 22a of the cross-flow volute. The heat exchange airflow passing through the heat exchanger 31 flows directly into the inlet 22a of the cross-flow volute, without the need for an additional sealing plate to connect the heat exchanger 31 and the fan component 2 to prevent airflow from escaping. This reduces manufacturing costs and the overall volume of the machine body.

[0044] The extended shape of the rear extension 311 can also serve as a guide, directing the heat-exchanged airflow to the fan component 2 and improving the sluggish loss of airflow inside the air conditioner 100.

[0045] And, as Figure 3 As shown, the air conditioner 100 of this utility model can be used in the corner 200. The rear wall 14 is set towards the rear wall 201, and the second side wall 1b is set towards the side wall 202. This not only reduces the difficulty of arranging the air conditioner 100, but also provides a larger area on the housing 1 for the air inlet 15, which can increase the air volume. The dotted line with arrows in the figure indicates the direction of airflow.

[0046] According to the embodiment of the present invention, the air conditioner 100 extends the rear end 311a of the heat exchanger 31 directly to the inlet 22a of the cross-flow volute. The heat exchange airflow through the heat exchanger 31 flows directly into the inlet 22a of the cross-flow volute without the need for an additional sealing plate 5 to connect the heat exchanger 31 and the fan component 2. This reduces manufacturing costs and the overall volume of the unit, reduces the floor space, and facilitates the arrangement of the air conditioner 100.

[0047] In some embodiments of this utility model, such as Figure 3 As shown, in the horizontal cross-section of the air conditioner 100, the cross-flow volute 22 includes a first air duct wall 221 and a second air duct wall 222 spaced apart to form a cross-flow air duct 223 between the first air duct wall 221 and the second air duct wall 222. The cross-flow fan 21 is located at the inlet of the cross-flow air duct 223. The second air duct wall 222 is located near the rear wall surface 14 relative to the first air duct wall 221. The rear end 311a extends to the inlet end of the second air duct wall 222 and is sealed to the inlet end of the second air duct wall 222.

[0048] The first air duct wall 221 is positioned close to the front wall 13 relative to the second air duct wall 222, and the cross-flow volute 22 is inclined in the left and right directions along the front-back direction, which helps to save space in the front-back direction.

[0049] The second air duct wall 222 is disposed relative to the first air duct wall 221 near the rear wall surface 14. The second air duct wall 222 is located near the rear end 311a of the heat exchanger 31 relative to the first air duct wall 221, so the rear end 311a extends to the inlet end of the second air duct wall 222. The rear end 311a is sealed to the inlet end of the second air duct wall 222, and the heat exchange airflow through the heat exchanger 31 flows directly into the cross-flow air duct 223, which can reduce the escape of the heat exchanged airflow from the air conditioner 100 and reduce air volume and heat loss.

[0050] In some embodiments of this utility model, such as Figure 3 As shown, the heat exchanger 31 is located on the side of the cross-flow impeller 21 near the second sidewall 1b in the left-right direction, and the axis of the cross-flow impeller 21 is located on the side of the rear end 311a near the first sidewall 1a in the left-right direction.

[0051] The air inlet 15 of the air conditioner 100 is at least partially formed on the second side wall 1b. The heat exchanger 31 is located on the side of the cross-flow fan 21 near the second side wall 1b in the left-right direction, so that the incoming air passes through the heat exchanger 31 first and then flows to the cross-flow fan 21. The heat exchanger 31 is arranged close to the second side wall 1b as a whole, which can simplify the arrangement of the heat exchanger 31.

[0052] The rear end 311a of the heat exchanger 31 gradually extends toward the inlet end of the second air duct wall 222 in the direction from the second side wall 1b to the first side wall 1a, and the rear end 311a does not exceed the axis of the cross-flow impeller 21 in the left-right direction, which can reduce the size superposition in the front-back direction and help save space in the front-back direction.

[0053] In some embodiments of this utility model, such as Figure 3 As shown, the distance between the rear end 311a and the axis of the cross-flow wind turbine 21 in the left-right direction is a first distance L1, which is greater than half of the radius R of the cross-flow wind turbine 21.

[0054] The first distance L1 between the rear end 311a and the axis of the cross-flow impeller 21 in the left-right direction is relatively large, which can reduce the superposition of the dimensions of the rear end 311a and the cross-flow impeller 21 in the front-back direction, and help save space in the front-back direction.

[0055] In some embodiments of this utility model, such as Figure 4 As shown, the air inlet 15 of the air conditioner 100 includes a rear air inlet 152 formed on the rear wall surface 14. 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 rear end portion 311a is located in the left-right direction on the side of the rear air inlet 152 close to the first side wall 1a.

[0056] The second side wall 1b of the rear air inlet 152 is provided, and the rear end 311a is located on one side of the first side wall 1a of the rear air inlet 152. The rear end 311a extends to the side of the rear air inlet 152 in the left and right direction toward the rear wall surface 14, which can increase the left and right length of the rear extension 311. The airflow entering the air conditioner 100 from the rear air inlet 152 can also be heat exchanged through the heat exchanger 31, increasing the heat exchange area and improving the heat exchange efficiency.

[0057] In some embodiments of this utility model, such as Figure 4 As shown, the rear wall surface 14 includes an inclined wall portion 141, which is disposed close to the second side wall 1b relative to the first side wall 1a. The inclined 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. The rear air inlet 152 is formed on the inclined wall portion 141.

[0058] By setting the inclined wall portion 141, which is set at an angle to the second side wall 1b, and the rear air inlet 152 is set on the inclined wall portion 141, when the rear wall surface 14 is set against the wall, the rear air inlet 152 and the rear wall 201 can be set at an angle, which can increase the gap between the air conditioner 100 and the wall, which is conducive to airflow. The dotted line with arrows in the figure is the direction of airflow, which is conducive to increasing the air intake volume of the rear air inlet 152.

[0059] In some embodiments of this utility model, such as Figure 4 As shown, the distance between the axis of the cross-flow impeller 21 and the rear wall surface 14 of the housing 1 in the front-rear direction is the third distance L3, which is less than 1.5 times the radius R of the cross-flow impeller 21.

[0060] The distance L3 between the axis of the cross-flow impeller 21 and the rear wall 14 of the housing 1 in the front-to-back direction is less than 1.5R, which can reduce the size of the housing 1 in the front-to-back direction and reduce the footprint in the front-to-back direction.

[0061] In some embodiments of this utility model, such as Figure 4 As shown, the air inlet 15 of the air conditioner 100 also includes a forward air inlet 153 formed on the front wall surface 13 of the housing 1, and the heat exchanger 31 also includes a front extension 312 that extends gradually toward the front wall surface 13 from the second side wall 1b to the first side wall 1a. The end of the front extension 312 away from the second side wall 1b is the front end 312a, which is spaced apart from the inlet end of the first air duct wall 221 and sealed and connected by the sealing plate 5.

[0062] The air conditioner 100 can not only draw air through the air inlet 15 on the second side wall 1b and the air inlet 15 on the rear wall 14, but also through the front air inlet 153 on the front wall 13. The dotted line with arrows in the figure indicates the direction of airflow, which helps to increase the air intake of the air conditioner 100.

[0063] The heat exchanger 31 is used to exchange heat with the airflow flowing in from the air inlet 15. A portion of the front extension 312 of the heat exchanger 31 is located behind the front air inlet 153, which can improve the heat exchange efficiency of the airflow flowing into the air conditioner 100 from the front air inlet 153.

[0064] The front end 312a of the heat exchanger 31 is sealed to the inlet end of the first air duct wall 221 by a sealing plate 5, thereby separating the air intake and exhaust airflow of the air conditioner 100. This reduces the occurrence of airflow in the cross-flow duct 223 flowing directly back to the heat exchanger 31 from the inlet end of the first air duct wall 221, reducing the return air phenomenon and helping to reduce the air volume loss of the air conditioner 100; it also reduces the occurrence of airflow entering from the front air inlet 153 flowing directly into the cross-flow duct 223, which helps to improve the air outlet effect of the air conditioner 100.

[0065] In some embodiments of this utility model, such as Figure 4 As shown, the heat exchanger 31 is located on the side of the cross-flow impeller 21 near the second sidewall 1b in the left-right direction, and the axis of the cross-flow impeller 21 is located on the side of the front end 312a near the first sidewall 1a in the left-right direction.

[0066] The front end portion 312a of the heat exchanger 31 gradually extends toward the front wall surface 13 in the direction from the second side wall 1b to the first side wall 1a, and the front end portion 312a does not exceed the axis of the cross-flow duct 223 in the left-right direction. This can reduce the superposition of the dimensions of the front end portion 312a of the heat exchanger 31 and the cross-flow impeller 21 in the front-back direction, which is beneficial to saving space in the front-back direction.

[0067] In some embodiments of this utility model, such as Figure 4 As shown, the distance between the front end 312a and the axis of the cross-flow wind turbine 21 in the left and right direction is the second distance L2, which is greater than half of the radius R of the cross-flow wind turbine 21.

[0068] The second distance L2 between the front end 312a and the axis of the cross-flow impeller 21 in the left-right direction is relatively large, which can reduce the superposition of the dimensions of the front end 312a and the cross-flow impeller 21 in the front-back direction, and help save space in the front-back direction.

[0069] In some embodiments of this utility model, such as Figure 5As shown, the front air inlet 153 is positioned in the left-right direction relative to the first side wall 1a and close to the second side wall 1b, and the front end portion 312a is located in the left-right direction on the side of the front air inlet 153 close to the first side wall 1a.

[0070] The front air inlet 153 is located close to the second side wall 1b. The front air inlet 153 and the air inlet 15 on the second side wall 1b are located close to each other. The air inlets 15 are arranged in a concentrated manner, which can improve the air intake effect.

[0071] The front end portion 312a is located on the side of the front air inlet 153 near the first side wall 1a in the left-right direction. In the left-right direction, the front end portion 312a extends beyond the edge of the front air inlet 153 near the first side wall 1a, which can increase the left-right length of the front extension portion 312, increase the heat exchange area, and improve the heat exchange efficiency of the airflow flowing in from the front air inlet 153.

[0072] In some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, the intersection of the first sidewall 1a and the front wall surface 13 of the housing 1 is the air outlet corner 17. The air outlet 16 of the air conditioner 100 is formed at the air outlet corner 17. The front wall surface 13 includes a first edge 131 that defines the air outlet 16 near the side edge of the second sidewall 1b. The distance between the front end 312a and the first edge 131 in the left-right direction is a fifth distance L5, which is greater than 50mm.

[0073] When the air conditioner 100 is used in a corner 200, the air outlet corner 17 is arranged away from the corner 200. The air outlet 16 located at the air outlet corner 17 can generate airflow in both the side and front directions. Compared with airflow only from the front or only from the side, the air outlet angle of the air conditioner 100 is larger, which can improve the airflow effect. Furthermore, the side air inlet 151 formed on the second side wall 1b and the rear air inlet 152 formed on the rear wall 14 of the housing 1 are far from the air outlet 16, which reduces the risk of backflow short circuit.

[0074] The air conditioner 100 can not only draw air through the side air inlet 151 on the second side wall 1b and the rear air inlet 152 on the rear wall 14, but also through the front air inlet 153 on the front wall 13. By limiting the distance between the front end 312a and the first edge 131 in the left and right directions to be greater than 50mm, the distance between the air outlet 16 and the front air inlet 153 is increased, reducing the situation where the air outlet of the air conditioner 100 flows directly back to the air conditioner 100 from the front air inlet 153, reducing the front return air phenomenon, and helping to reduce the air volume loss of the air conditioner 100.

[0075] In some embodiments of this utility model, such as Figure 5 and Figure 6As shown, the intersection of the first sidewall 1a and the front wall 13 of the housing 1 is the air outlet corner 17. The air outlet 16 of the air conditioner 100 is formed at the air outlet corner 17. The cross-flow volute 22 extends from the inlet 22a of the cross-flow volute to the outlet 22b of the cross-flow volute in the direction close to the air outlet 16.

[0076] An air outlet 16 is provided at the intersection of the first side wall 1a and the front wall 13 of the housing 1. When the air conditioner 100 is used in the corner 200, the air outlet 16 can generate airflow in both the side and front directions, and the air supply angle of the air conditioner 100 is relatively large. In addition, the air outlet 16 is located away from the side air outlet 16 on the second side wall 1b and the rear air outlet 16 on the rear wall 14, which can reduce the phenomenon of backflow.

[0077] like Figure 5 As shown, the cross-flow volute 22 extends from the cross-flow impeller 21 toward the air outlet 16. The outlet 22b of the cross-flow volute is located on the side of the cross-flow impeller 21 near the first side wall 1a. The cross-flow impeller 21 is inclined in the front-back direction toward the left-right direction, which helps to save space in the front-back direction.

[0078] In some embodiments of this utility model, such as Figure 5 and Figure 6 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.

[0079] This saves space in the front-to-back direction, which helps to reduce the overall size of the unit in the front-to-back direction and reduce its floor space. 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.

[0080] In some embodiments of this utility model, such as Figure 3 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 14 is disposed near the rear wall 201 relative to the front wall 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 14 and the front wall 13 of the housing 1 is a flat plate structure, adapted to be arranged parallel to the rear wall 201.

[0081] 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 its space occupation. At least a portion of the front wall 13 is a flat plate structure, and the arrangement of the air conditioner 100 parallel to the rear wall 201 can increase the air supply angle of the air conditioner 100 and improve the air supply effect.

[0082] In some embodiments of this utility model, such as Figure 4 As shown, the rear wall 14 includes an inclined wall portion 141 and a flat portion 142. The flat portion 142 is formed as a plane extending in a straight line in the left-right direction. The inclined wall portion 141 extends obliquely relative to the flat portion 142 in a direction from back to front. The rear air inlet 152 is formed on the inclined wall portion 141.

[0083] By providing the flat section 142, when the air conditioner 100 is used in a corner, it is easier for the air conditioner 100 to be arranged parallel to the rear wall 201, and the air supply angle of the air conditioner 100 can be increased. Furthermore, by providing the sloping wall section 141, when the rear wall surface 14 is set against the wall, the gap between the air conditioner 100 and the wall can be increased, which is conducive to airflow and helps to increase the air intake volume of the rear air inlet 152.

[0084] In some embodiments of this utility model, such as Figure 2 As shown, the air conditioner 100 also includes an air guide component 4 disposed at the air outlet 16. The air guide component 4 can guide the airflow of the air outlet 16 and improve the air outlet effect of the air conditioner 100.

[0085] like Figure 2 As shown, the air guide component 4 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 4, 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.

[0086] like Figure 3 As shown, the air guide component 4 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.

[0087] like Figure 4 As shown, the air guide component 4 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.

[0088] like Figure 5 As shown, the air guide component 4 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 towards the front is directly delivered to the center of the room or blown directly on the user, which can quickly regulate the user's body surface temperature.

[0089] In some embodiments of this utility model, the air guiding component 4 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.
