[0030] 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.

[0031] 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.

[0032] The air conditioner 100 of this utility model is described below with reference to the accompanying drawings.

[0033] 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 and a ventilation and heat exchange component 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 outlet 16 of the air conditioner 100 is formed on the first side wall 1a and / or the front wall surface 13 of the housing 1. The air inlet 17 of the air conditioner 100 includes a side air inlet 172 formed on the second side wall 1b and a rear air inlet 173 formed on the rear wall surface 14 of the housing 1. The ventilation and heat exchange component 2 is disposed inside the housing 1 and is used to draw in airflow from the air inlet 17, exchange heat with the airflow, and then send the airflow out from the air outlet 16.

[0034] The air conditioner 100 of this utility model embodiment can be used at a corner 200, with the second side wall 1b and the rear wall 14 close to the wall; the air conditioner 100 of this utility model embodiment can also be used close to the wall, with the second side wall 1b close to the wall, or the rear wall 14 close to the wall.

[0035] When used in a corner 200, the rear wall 14 can be set towards the rear wall 201, and the second side wall 1b can be set towards the side wall 202. In this case, the housing 1 has a larger area for the air inlet 17, which can increase the air volume. The dotted line with arrows in the figure indicates the direction of airflow. Furthermore, the air outlet 16 is far away from the rear wall 201 and / or far away from the side wall 202, which makes it less likely to form a short circuit problem and reduces air volume loss.

[0036] Optionally, such as Figure 2As shown, the right wall 12 of the housing 1 is the first side wall 1a, the left wall 11 of the housing 1 is the second side wall 1b, a side air inlet 172 is formed on the left wall 11, and an air outlet 16 is formed on the right wall 12 and / or the front wall 13. At this time, the left wall 11 of the air conditioner 100 can be set close to the corner 200, and the air conditioner 100 can take in air through the front wall 13 and the left wall 11.

[0037] Alternatively, the left wall 11 of the housing 1 is a first side wall 1a, the right wall 12 of the housing 1 is a second side wall 1b, a side air inlet 172 is formed on the right wall 12, and an air outlet 16 is formed on the left wall 11 and / or the front wall 13. In this case, the right wall 12 of the air conditioner 100 can be set close to the corner 200, and the air conditioner 100 can take in air through the front wall 13 and the right wall 12.

[0038] One of the left wall surface 11 and the right wall surface 12 of the housing 1 is designated as the first side wall 1a, and the other is designated as the second side wall 1b. This can be selected according to actual needs to expand the application range of the air conditioner 100. For example, when the right wall of a user's living room is filled with large appliances, while the left wall has sufficient space, an air conditioner 100 with the left wall surface 11 designated as the second side wall 1b can be selected and placed at the corner 200 of the left wall 202. The placement of the air conditioner 100 is relatively simple.

[0039] The ventilation and heat exchange component 2 is used to provide airflow. The ventilation and heat exchange component 2 draws in airflow from the air inlet 17 and then sends the airflow out from the air outlet 16. The ventilation and heat exchange component 2 also exchanges heat on the airflow and sends the heat-exchanged airflow out from the air outlet 16 to regulate the indoor temperature.

[0040] According to the embodiment of the present utility model, when the air conditioner 100 is used in a corner 200, the rear wall is set towards the rear wall 201 and the second side wall 1b is set towards the side wall 202. At this time, the housing 1 has a larger area for the air inlet 17, which can increase the air intake volume. Furthermore, the air outlet 16 is far away from the rear wall 201 and / or far away from the side wall 202, which makes it less likely to form a short circuit problem of return air and can reduce air volume loss.

[0041] In some embodiments of this utility model, such as Figure 3 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 173 is formed on the inclined wall portion 141.

[0042] By setting the inclined wall portion 141, which is set at an angle to the second side wall 1b, and the rear air inlet 173 is set on the inclined wall portion 141, when the rear wall surface 14 is set against the wall, the rear air inlet 173 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 schematic direction of airflow, which is conducive to increasing the air intake volume of the rear air inlet 173.

[0043] In some embodiments of this utility model, such as Figure 3 As shown, the second sidewall 1b is formed as a plane, and the angle between the inclined wall portion 141 and the second sidewall 1b is an obtuse angle.

[0044] The inclined wall portion 141 extends obliquely from front to back relative to the second side wall 1b, which forms a plane extending in a straight line from front to back. The angle between the inclined wall portion 141 and the second side wall 1b is an obtuse angle. The smaller the inclination angle of the inclined wall portion 141 relative to the second side wall 1b, the better the space utilization of the arrangement position and the smaller the space occupied by the air conditioner 100. Moreover, compared to the acute angle formed between the inclined wall portion 141 and the second side wall 1b, the obtuse angle between the inclined wall portion 141 and the second side wall 1b can improve the arrangement stability of the air conditioner 100.

[0045] In some embodiments of this utility model, such as Figure 3 As shown, the rear wall surface 14 includes a flat portion 142, which is connected to the side of the inclined wall portion 141 near the first side wall 1a. The included angle between the flat portion 142 and the inclined wall portion 141 is a first included angle C, which is an obtuse angle.

[0046] The inclined wall portion 141 extends obliquely relative to the flat portion 142 in a direction from back to front. The flat portion 142 is formed as a plane extending in a straight line in the left and right direction. The angle between the inclined wall portion 141 and the flat portion 142 is an obtuse angle. The inclination angle of the inclined wall portion 141 relative to the flat portion 142 is small. While increasing the air intake volume of the rear air inlet 173 on the inclined wall portion 141, it can improve the space utilization rate of the air conditioner 100 in the arrangement space, which is conducive to reducing the space occupied by the air conditioner 100.

[0047] In some embodiments of this utility model, such as Figure 3 As shown, the supplementary angle of the first included angle C is the first supplementary angle A, which is an acute angle and greater than 5°.

[0048] It is understandable that the first supplementary angle A is the supplementary angle of the first included angle C. The sum of the angles of the first supplementary angle A and the first included angle C is 180°. Since the first supplementary angle A is an acute angle and greater than 5°, the first included angle C is an obtuse angle and less than 175°.

[0049] When the first supplementary angle A is too small, the inclined wall portion 141 approaches a plane parallel to the left and right directions, and the gap between the rear air inlet 173 on the inclined wall portion 141 and the rear wall 201 is too small, resulting in poor air intake effect of the rear air inlet 173. Therefore, when the first supplementary angle A is greater than 5°, the gap between the air conditioner 100 and the wall can be increased, which is beneficial to airflow and helps to increase the air intake volume of the rear air inlet 173.

[0050] In some embodiments of this utility model, such as Figure 4 As shown, the ventilation and heat exchange component 2 includes a heat exchange component 22, which includes a heat exchanger 221. The heat exchanger 221 includes a rear extension 2212 extending from the side air inlet 172 toward the rear air inlet 173. The angle between the extension direction of the end of the rear extension 2212 away from the side air inlet 172 and the planar portion 142 is a second angle D, which is an obtuse angle.

[0051] The heat exchanger 221 is used to exchange heat with the airflow flowing in from the air inlet 17. The rear extension 2212 of the heat exchanger 221 is located near the side air inlet 172 and the rear air inlet 173. This simplifies the arrangement of the heat exchanger 221 and improves the heat exchange efficiency of the heat exchanger 221 for the airflow.

[0052] The angle between the extension direction of the end of the rear extension 2212 and the planar portion 142 is represented by the degree of inclination of the end of the rear extension 2212 relative to the planar portion 142. By limiting the second angle D to an obtuse angle, the degree of inclination of the rear extension 2212 portion of the heat exchanger 221 relative to the planar portion 142 is smaller, and the space extending along the planar portion 142 is larger, which is beneficial to increasing the volume of the heat exchanger 221, thereby improving the heat exchange efficiency of the airflow.

[0053] In some embodiments of this utility model, such as Figure 4 As shown, the supplementary angle of the first included angle C is the first supplementary angle A, and the supplementary angle of the second included angle D is the second supplementary angle B. The second supplementary angle B is less than or equal to 85°, the second supplementary angle B is greater than or equal to the first supplementary angle A, and the first supplementary angle A is greater than 5°.

[0054] When the first supplementary angle A is too small, the inclined wall portion 141 approaches a plane parallel to the left and right directions, and the gap between the rear air inlet 173 on the inclined wall portion 141 and the rear wall 201 is too small, resulting in poor air intake effect of the rear air inlet 173. Therefore, when the first supplementary angle A is greater than 5°, the gap between the air conditioner 100 and the wall can be increased, which is beneficial to airflow and helps to increase the air intake volume of the rear air inlet 173.

[0055] The second supplementary angle B is the supplement of the second included angle B. The sum of the angles of the second supplementary angle B and the second included angle D is 180°. If the second supplementary angle B is less than or equal to 85°, then the second included angle D is an obtuse angle and greater than or equal to 95°.

[0056] When the second supplementary angle B is smaller than the first supplementary angle A, the rear extension 2212 of the heat exchanger 221 is positioned close to the rear air inlet 173 on the inclined wall 141. The distance between the heat exchanger 221 and the rear air inlet 173 is too close, which will not only increase the wind resistance at the rear air inlet 173 and affect the air intake of the rear air inlet 173, but also affect the heat exchange effect of the heat exchanger 221.

[0057] Therefore, in some embodiments of this utility model, the second supplementary angle B is limited to be greater than or equal to the first supplementary angle A, which can increase the air volume of the rear air inlet 173 and improve the heat exchange effect of the heat exchanger 221 on the air intake of the rear air inlet 173.

[0058] In some embodiments of this utility model, such as Figure 3 As shown, the end of the inclined wall portion 141 near the second side wall 1b is connected to the rear end of the second side wall 1b.

[0059] The inclined wall 141 is not separated from the second side wall 1b, which allows the rear air inlet 173 and the side air inlet 172 to be arranged in a concentrated manner, which is conducive to the concentrated arrangement of the air inlet filter and the heat exchange components 22 at the air inlet.

[0060] In some embodiments of this utility model, such as Figure 3 and Figure 5 As shown, the ventilation and heat exchange component 2 includes a heat exchange component 22 and a fan component 21. The heat exchange component 22 is positioned relative to the fan component 21 near the air inlet 17. The fan component 21 includes a vertically oriented cross-flow impeller 211. The rear air inlet 173 is positioned in the left-right direction relative to the central axis of the cross-flow impeller 211 near the second side wall 1b.

[0061] A cross-flow fan 211 provides airflow, and a heat exchange component 22 transfers heat to the airflow to regulate the indoor temperature. The heat exchange component 22 is positioned relative to the fan component 21 near the air inlet 17. The rear air inlet 173 is positioned in the left-right direction relative to the central axis of the cross-flow fan 211 near the second sidewall 1b, and the air outlet 16 is positioned in the left-right direction relative to the central axis of the cross-flow fan 211 near the first sidewall 1a. The concentrated arrangement of the heat exchange component 22 relative to the fan component 21 on the side near the second sidewall 1b facilitates the centralized arrangement of the heat exchange component 22 and improves the heat exchange efficiency of the airflow.

[0062] In some embodiments of this utility model, such as Figure 5 and Figure 6As 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 its width. This 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.

[0063] like Figure 2 , Figure 5 and Figure 6 As shown, the air outlet 16 is located at the intersection of the first side wall 1a and the front wall 13 of the housing 1. When used in a corner 200, the air outlet 16 is positioned away from the corner 200. The air outlet 16 can generate airflow in both the side and front directions. The dotted lines with arrows in the figure indicate the direction of airflow. Compared to solutions with only front or side airflow, the air supply angle of the air conditioner 100 is larger, which can improve the air supply effect. Furthermore, the air inlet 17 formed on the second side wall 1b and the rear wall 14 of the housing 1 is far from the air outlet 16, which reduces the risk of backflow short circuits. The housing 1 also has a larger area for the air inlet 17, increasing the air volume.

[0064] In some embodiments of this utility model, such as Figure 4 As shown, the air inlet 17 includes a forward air inlet 171 formed on the front wall surface 13. The forward air inlet 171 is disposed in the left-right direction relative to the central axis of the cross-flow impeller 211 and close to the second side wall 1b. The ventilation and heat exchange component 2 includes a heat exchange component 22, which includes a heat exchanger 221. The heat exchanger 221 includes a front extension 2211 extending from the side air inlet 172 toward the forward air inlet 171.

[0065] The air conditioner 100 can draw air not only through the air inlet 17 on the second side wall 1b and the air inlet 17 on the rear wall 14, but also through the air inlet 17 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.

[0066] The front air vent 171 is positioned close to the second side wall 1b relative to the central axis of the cross-flow fan 211 in the left-right direction. The front air vent 171 is positioned far away from the air outlet 16 in the left-right direction. This reduces the situation where the air outlet of the air conditioner 100 flows directly back to the air conditioner 100 from the front air vent 171, reduces the front return air phenomenon, and reduces the air volume loss of the air conditioner 100.

[0067] The front extension 2211 of the heat exchanger 221 extends toward the rear side of the air inlet 171, which can improve the heat exchange efficiency of the airflow flowing into the air conditioner 100 from the air inlet 171. In some embodiments, such as Figure 4As shown, the heat exchanger 221 includes a front extension 2211 and a rear extension 2212. The front extension 2211 extends from the side air inlet 172 toward the front air inlet 171, and the rear extension 2212 extends from the side air inlet 172 toward the rear air inlet 173. The heat exchanger 221 can meet the heat exchange requirements of the airflow at the front air inlet 171, the side air inlet 172 and the rear air inlet 173, thereby improving the heat exchange efficiency.

[0068] In some embodiments of this utility model, such as Figure 2 As shown, the air conditioner 100 is adapted to be installed 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 first side wall 1a. 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.

[0069] 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.

[0070] 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.

[0071] like Figure 3 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.

[0072] like Figure 2 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.

[0073] 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.

[0074] like Figure 5As 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.
