[0032] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals indicate the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0033] The air conditioner indoor unit 100 according to the embodiment of the present invention will be described below with reference to the drawings.

[0034] Referring to Figure 1 , Figure 2 As shown, the air conditioner indoor unit 100 according to the embodiment of the present invention includes: a casing 10, an impeller 20 and a heat exchanger 30.

[0035] The housing 10 is provided with a top wall 11 and a first front wall 12. The first front wall 12 is located at the front side of the housing 10 relative to the top wall 11, and is inclined relative to the top wall 11 toward a side close to the inside of the housing 10. The angle between the first front wall 12 and the top wall 11 is an obtuse angle, and the first front wall 12 is provided with an air inlet 121. The wind wheel 20 is provided in the housing 10. The heat exchanger 30 is provided in the housing 10, and is located between the wind wheel 20 and the air inlet 121.

[0036] Specifically, the wind wheel 20 guides the airflow to enter the housing 10 from the air inlet 121, and the airflow flows through the heat exchanger 30 to complete heat exchange.

[0037] In the related art, in order to ensure air intake, the indoor unit of the air conditioner is usually separated from the ceiling by a certain distance, resulting in a waste of space.

[0038] In the embodiment of the utility model, the first front wall 12 is provided with an air inlet 121, so that the top wall 11 can be against the ceiling, and the air conditioner indoor unit 100 is close to the ceiling, avoiding waste of space. Of course, it can be understood that the ceiling is a specific example here, and the ceiling can be replaced by other surfaces of a building or the surface of other objects, wherein the other surfaces of the building or the surface of other objects are higher than the air conditioner indoor unit 100, such as a suspended ceiling.

[0039] Among them, the first front wall 12 is located on the front side of the casing 10 relative to the top wall 11. It can be understood that the air-conditioning indoor unit 100 is usually installed on a vertical wall, the direction of the air-conditioning indoor unit 100 facing the vertical wall is the rear, and the direction of the air-conditioning indoor unit 100 facing away from the vertical wall is the front. The first front wall 12 is located on the front side of the casing 10, that is, the first front wall 12 is located on the side of the casing 10 away from the vertical wall.

[0040] The first front wall 12 is inclined relative to the top wall 11 toward the side of the housing 10. Figure 1 As shown, the side relatively close to the inside of the housing 10 is the lower side, that is, the first front wall 12 is arranged to be inclined downward.

[0041] Among them, the angle between the first front wall 12 and the top wall 11 is an obtuse angle, that is, the angle between the first front wall 12 and the top wall 11 is in the range of 90° to 180° (excluding 90° or 180°), that is to say, the first front wall 12 extends obliquely downward. Compared with the solution of setting an air inlet on a vertical plane in the related technology, in the embodiment of the utility model, the first front wall 12 extends obliquely downward. When the first front wall 12 is at the same height and length as the vertical plane, the area of ​​the first front wall 12 is larger, so that an air inlet 121 with a larger area can be set, thereby increasing the air intake volume.

[0042] According to the air conditioner indoor unit 100 of the embodiment of the present utility model, by providing an air inlet 121 on the first front wall 12, the air conditioner indoor unit 100 can be abutted against the ceiling, avoiding waste of space. At the same time, the included angle between the first front wall 12 and the top wall 11 is set to be an obtuse angle, so that the area of the air inlet 121 can be set larger, and the air intake volume can be made larger.

[0043] Referring to the attached Figure 1 As shown, it can be understood that the included angle between the first front wall 12 and the top wall 11 is θ, and θ ≤ 140°.

[0044] In the above solution, the included angle θ between the first front wall 12 and the top wall 11 is θ ≤ 140°. When the air conditioner indoor unit 100 is abutted against the ceiling, there is a certain space between the first front wall 12 and the ceiling, thus ensuring the air intake volume. Compared with the solution in the related art where the first front wall is too close to the ceiling, in the embodiment of the present utility model, the included angle θ between the first front wall 12 and the top wall 11 is set to be θ ≤ 140°, and there is a certain space between the first front wall 12 and the ceiling, which improves the air intake problem.

[0045] Specifically, the included angle θ between the first front wall 12 and the top wall 11 can be 140°; or, the included angle θ between the first front wall 12 and the top wall 11 can be 139°; or, the included angle θ between the first front wall 12 and the top wall 11 can be 138°; or, the included angle θ between the first front wall 12 and the top wall 11 can be 130°; or, the included angle θ between the first front wall 12 and the top wall 11 can be 125°; or, the included angle θ between the first front wall 12 and the top wall 11 can be 120°; or, the included angle θ between the first front wall 12 and the top wall 11 can be 115°; or, the included angle θ between the first front wall 12 and the top wall 11 can be 110°; or, the included angle θ between the first front wall 12 and the top wall 11 can be 105°; or, the included angle θ between the first front wall 12 and the top wall 11 can be 100°; or, the included angle θ between the first front wall 12 and the top wall 11 can be 95°; or, the included angle θ between the first front wall 12 and the top wall 11 can be 91°.

[0046] Referring to Figure 1 、 Figure 2 As shown, it can be understood that the heat exchanger 30 includes a first part 31 close to the first front wall 12, and the first part 31 is parallel to the first front wall 12; wherein, the included angle θ between the first front wall 12 and the top wall 11 is θ ≥ 105°.

[0047] It should be noted that in the above solution, the fact that the first part 31 is parallel to the first front wall 12 does not mean that the first part 31 has to be strictly completely parallel to the first front wall 12. It can be understood that the first part 31 can have a small inclination angle relative to the first front wall 12, such as an inclination angle of 0.5°, 1°, or 1.5°, etc. Under the premise of the air conditioner indoor unit 100, the small inclination angle has no substantial impact.

[0048] In the above solution, the included angle θ between the first front wall 12 and the top wall 11 is θ≥105°. Compared with the solution in the related art where the included angle θ between the first front wall and the top wall is less than 105°, in the related art, the heat exchanger is basically vertically placed, and the top end of the heat exchanger is far from the wind wheel, resulting in the top end of the heat exchanger becoming a dead corner position of the air flow. In the embodiment of the present invention, the included angle θ between the first front wall 12 and the top wall 11 is θ≥105°, and the first part 31 is parallel to the first front wall 12. That is to say, the first part 31 is relatively gentle compared with the heat exchanger in the related art. With the same position of the wind wheel, the air flow can flow through each part of the first part 31, avoiding the problem of dead corners in the related art and improving the performance.

[0049] It should be noted that the first part 31 is parallel to the first front wall 12, and the included angle θ between the first front wall 12 and the top wall 11 is θ≤140°. Compared with the solution in the related art where the included angle θ between the first front wall and the top wall is greater than 140°, in the related art, the attitude of the first part is relatively horizontal. Simply understood, in the related art, the first part is horizontally placed, resulting in the condensed water on the first part dripping randomly. In the embodiment of the present invention, the included angle θ between the first front wall 12 and the top wall 11 is θ≤140°, making the first part 31 inclined, and the condensed water on the first part 31 drips downward along the surface of the first part 31 under the action of its own gravity, thus avoiding the situation of random dripping of condensed water in the related art and improving the internal environment of the air conditioner indoor unit 100.

[0050] Specifically, the included angle θ between the first front wall 12 and the top wall 11 is 105°; or, the included angle θ between the first front wall 12 and the top wall 11 is 110°; or, the included angle θ between the first front wall 12 and the top wall 11 is 115°; or, the included angle θ between the first front wall 12 and the top wall 11 is 120°; or, the included angle θ between the first front wall 12 and the top wall 11 is 120°; or, the included angle θ between the first front wall 12 and the top wall 11 is 125°; or, the included angle θ between the first front wall 12 and the top wall 11 is 130°; or, the included angle θ between the first front wall 12 and the top wall 11 is 135°; or, the included angle θ between the first front wall 12 and the top wall 11 is 140°.

[0051] Refer to Figure 3 、 Figure 4As shown, it can be understood that the housing 10 includes: a housing main body 13 and an air inlet grille 14.

[0052] The housing main body 13 is provided with a top wall 11 and a first front wall 12. The air inlet grille 14 is detachably arranged on the housing main body 13 and at least partially located on the first front wall 12.

[0053] In the above solution, the air inlet grille 14 is detachably arranged on the housing main body 13. During the later maintenance process, for example, when cleaning the heat exchanger 30 or replacing the electric control unit 40, it is convenient for the operator to operate, making the maintenance process more simple.

[0054] Among them, the air inlet grille 14 plays a role in preventing foreign objects from entering the air conditioner indoor unit 100. The air inlet grille 14 covers the air inlet 121. Larger foreign objects cannot pass through the air inlet grille 14 and enter the air conditioner indoor unit 100, while the air flow can pass through the air inlet grille 14 and enter the air conditioner indoor unit 100.

[0055] Specifically, the housing main body 13 is provided with a limiting groove, and the air inlet grille 14 is slidably inserted into the limiting groove. The structure is simple and the reliability is high; or, the housing main body 13 and the air inlet grille 14 are snap-connected by a buckle to improve the firmness.

[0056] More specifically, the air inlet grille 14 is fixed on the housing main body 13 by fastening screws, further improving the stability. During the later disassembly process, the fastening screws can be unscrewed using a screwdriver.

[0057] Referring to Figure 5 、 Figure 6 As shown, it can be understood that the first front wall 12 is provided with a maintenance opening 122. The air conditioner indoor unit 100 further includes an electric control unit 40. The electric control unit 40 is arranged inside the housing main body 13 and corresponds to the maintenance opening 122. The air inlet grille 14 includes: a grille part 141 and a shielding part 142. The grille part 141 corresponds to the air inlet 121, and the shielding part 142 is connected to the grille part 141. The shielding part 142 covers the maintenance opening 122.

[0058] Among them, the maintenance opening 122 is a notch provided on the first front wall 12. The operator operates on the electric control unit 40 through the maintenance opening 122, such as installing, disassembling, replacing, maintaining, and cleaning the electric control unit 40. It can be understood that the electric control unit 40 is the electric control unit of the air conditioner indoor unit 100. The electric control unit 40 is electrically connected to the components inside the air conditioner indoor unit 100 and controls them. For example, the electric control unit 40 controls the rotation of the air wheel 20.

[0059] In the above solution, the maintenance opening 122 is provided on the first front wall 12, the electronic control unit 40 is provided corresponding to the maintenance opening 122, and the air inlet grille 14 includes a shielding portion 142 covering the maintenance opening 122. That is to say, after the air inlet grille 14 is disassembled, the maintenance opening 122 and the electronic control unit 40 located within the maintenance opening 122 can be exposed in front of the operator's eyes. During the process of maintaining or replacing the electronic control unit 40, the electronic control unit 40 is always within the operator's line of sight, thus facilitating the operation of the operator.

[0060] In the related art, the maintenance opening faces upward, and the air conditioner indoor unit is usually installed at a relatively high position. If the operator wants to replace or maintain the electronic control unit, the operator can only grope bit by bit with his hands. In comparison, the solution of the embodiment of the present utility model facilitates the operation of the operator.

[0061] Referring to Figure 8 As shown, it can be understood that the first front wall 12 is provided with an open opening 123, and at least one connecting strip 1231 is provided within the open opening 123. The at least one connecting strip 1231 is arranged along the length direction of the open opening 123 and is connected to opposite ends of the open opening 123. The open opening 123 and the connecting strip 1231 together form an air inlet 121.

[0062] Among them, the open opening 123 and the connecting strip 1231 together form an air inlet 121. The connecting strip 1231 is arranged within the open opening 123, and the connecting strip 1231 is arranged along the length direction of the open opening 123. Referring to Figure 8 As shown, the length direction is the left - right direction, that is, the connecting strip 1231 extends along the left - right direction. The air inlet grille 14 corresponds to the air inlet 121. The air inlet grille 14 prevents larger foreign objects from entering the air conditioner indoor unit 100, and the air flow enters the air conditioner indoor unit 100 from outside the air conditioner outdoor unit through the air inlet grille 14 and the air inlet 121.

[0063] In the above solution, the area of the open opening 123 is relatively large, and the air inlet grille 14 is detachably arranged on the housing main body 13. It can be understood that when the air inlet grille 14 is disassembled from the housing main body 13, the open opening 123 is exposed within the operator's line of sight. The relatively large - area open opening 123 facilitates the operator to clean the interior of the air conditioner indoor unit 100, such as cleaning the heat exchanger 30. The relatively large - area open opening 123 facilitates the setting of a relatively large - area air inlet 121, and the operator can more conveniently extend the cleaning work into the interior of the air conditioner indoor unit 100.

[0064] Among them, the connecting strip 1231 is arranged along the length direction of the open opening 123, the connecting strip 1231 connects opposite ends of the open opening 123. The connecting strip 1231 makes the open opening 123 not easily deformed. At the same time, it can be understood that the connecting strip 1231 is arranged within the open opening 123, and the connecting strip 1231 supports the air inlet grille 14 to prevent the air inlet grille 14 from being recessed into the open opening 123.

[0065] Specifically, the holes on the air inlet grille 14 are relatively dense, while the area of the air inlet 121 on the main body 13 of the casing is relatively large. After removing the air inlet grille 14, the operator can insert a cleaning ball into the interior of the air conditioner indoor unit 100 to clean the heat exchanger 30.

[0066] Refer to Figure 7 As shown, it can be understood that the first front wall 12 is provided with an opening 123, and at least one connecting strip 1231 is provided in the opening 123. The at least one connecting strip 1231 is arranged along the width direction of the opening 123 and is connected to the opposite ends of the opening 123. The opening 123 and the connecting strip 1231 together form the air inlet 121.

[0067] Among them, the opening 123 and the connecting strip 1231 together form the air inlet 121. The connecting strip 1231 is arranged in the opening 123 and is arranged along the width direction of the opening 123. The air inlet grille 14 corresponds to the air inlet 121. The air inlet grille 14 prevents larger foreign objects from entering the air conditioner indoor unit 100, and the air flow enters the air conditioner indoor unit 100 from the outside of the air conditioner outdoor unit through the air inlet grille 14 and the air inlet 121.

[0068] In the above solution, the area of the opening 123 is relatively large, and the air inlet grille 14 is detachably arranged on the main body 13 of the casing. It can be understood that when the air inlet grille 14 is removed from the main body 13 of the casing, the opening 123 is exposed within the operator's sight. The relatively large area of the opening 123 facilitates the operator to clean the interior of the air conditioner indoor unit 100, such as cleaning the heat exchanger 30. The relatively large area of the opening 123 facilitates the setting of a relatively large area of the air inlet 121, and the operator can more conveniently insert the cleaning tool into the interior of the air conditioner indoor unit 100.

[0069] Among them, the connecting strip 1231 is arranged along the width direction of the opening 123, and the connecting strip 1231 connects the opposite ends of the opening 123. The connecting strip 1231 makes the opening 123 not easily deformed. At the same time, it can be understood that the connecting strip 1231 is arranged in the opening 123, and the connecting strip 1231 supports the air inlet grille 14 to prevent the air inlet grille 14 from being recessed into the opening 123.

[0070] Specifically, the holes on the air inlet grille 14 are relatively dense, while the area of the air inlet 121 on the main body 13 of the casing is relatively large. After removing the air inlet grille 14, the operator can insert a cleaning ball into the interior of the air conditioner indoor unit 100 to clean the heat exchanger 30.

[0071] Refer to Figure 9As shown, it can be understood that the first front wall 12 is provided with an opening 123. Inside the opening 123, there are multiple connecting bars 1231. At least one connecting bar 1231 is arranged along the length direction of the opening 123, and another connecting bar 1231 is arranged along the width direction and is connected to the opposite ends of the opening 123. The opening 123 and the connecting bars 1231 together form an air inlet 121.

[0072] Among them, the opening 123 and the connecting bars 1231 together form the air inlet 121. The connecting bars 1231 are arranged inside the opening 123. There are multiple connecting bars 1231. Some of the connecting bars 1231 are arranged along the width direction of the opening 123, and some of the other connecting bars 1231 are arranged along the length direction of the opening 123. The air inlet grille 14 corresponds to the air inlet 121. The air inlet grille 14 prevents larger foreign objects from entering the air conditioner indoor unit 100. The air flow enters the air conditioner indoor unit 100 from outside the air conditioner outdoor unit through the air inlet grille 14 and the air inlet 121.

[0073] In the above solution, the area of the opening 123 is relatively large, and the air inlet grille 14 is detachably arranged on the housing main body 13. It can be understood that when the air inlet grille 14 is detached from the housing main body 13, the opening 123 is exposed within the sight of the operator. The relatively large area of the opening 123 facilitates the operator to clean the interior of the air conditioner indoor unit 100, such as cleaning the heat exchanger 30. The relatively large area of the opening 123 facilitates the setting of a relatively large area of the air inlet 121, and the operator can more conveniently insert the cleaning tool into the interior of the air conditioner indoor unit 100.

[0074] Among them, there are multiple connecting bars 1231. Some of the connecting bars 1231 are arranged along the width direction of the opening 123, and some of the other connecting bars 1231 are arranged along the length direction of the opening 123. The multiple connecting bars 1231 are intertwined into a net. The connecting bars 1231 are connected to the opposite ends of the opening 123. The intertwined connecting bars 1231 make the opening 123 less likely to deform. At the same time, it can be understood that the connecting bars 1231 are arranged inside the opening 123, and the connecting bars 1231 support the air inlet grille 14 to prevent the air inlet grille 14 from recessing into the opening 123.

[0075] Specifically, the holes on the air inlet grille 14 are relatively dense, and the area of the air inlet 121 on the housing main body 13 is relatively large. After the air inlet grille 14 is detached, the operator can insert a cleaning ball into the interior of the air conditioner indoor unit 100 to clean the heat exchanger 30.

[0076] Refer to Figure 1 As shown, it can be understood that the heat exchanger 30 includes a first part 31 close to the first front wall 12, and the first part 31 is arranged close to the first front wall 12.

[0077] Among them, the first part 31 is close to the first front wall 12. That is to say, the distance between the first part 31 and the first front wall 12 is small, which facilitates the operator to use a cleaning tool for cleaning, such as a brush. The short distance makes the first part 31 close to the opening 123, and the brush does not need to extend into the opening 123 for a long distance to contact the first part 31.

[0078] Referring to Figure 9 As shown, it can be understood that the top wall 11 is provided with a first groove 111, and the first front wall 12 is provided with a second groove 124. The second groove 124 communicates with the first groove 111; the air inlet grille 14 includes a connected horizontal part 143 and an inclined part 144.
