DETAILED DESCRIPTION
-
Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The following embodiments described with reference to the accompanying drawing are illustrative. It should be understood that the embodiments described are intended to explain the present invention, but not to limit the present invention.
-
For the air-conditioner hanging unit adopting bottom air intake and top air outlet, a three-fold arrangement will lead to a tight internal space of an air conditioner, thus resulting in a compressed air flow space, and further resulting in issues such as an increased air resistance, an increased fan workload, and a higher air-conditioner energy consumption ratio, which increases user's use costs and also affects the uniformity of cooling or heating effect.
-
An air-conditioner indoor unit according to embodiments of the present invention may be a wall-mounted indoor unit. The air-conditioner indoor unit has an air inlet 5 and an air outlet 4 located above the air inlet 5. For example, as shown in FIG. 1, the air inlet 5 may be located at a bottom side of the air-conditioner indoor unit, and the air outlet 4 may be located at a top of a front side of the air-conditioner indoor unit.
-
As shown in FIG. 1, the air-conditioner indoor unit includes an air discharge frame 1, a base 2, and an evaporator 3. The air discharge frame 1 is arranged adjacent to the air outlet 4. For example, the air discharge frame 1 may be located at a bottom side of the air outlet 4. The air discharge frame 1 may be configured as at least part of a bottom air-duct wall of the air outlet 4.
-
The evaporator 3 includes a first component 31 and a second component 32 arranged at an included angle. A junction 33 between the first component 31 and the second component 32 protrudes towards the air inlet 5. An end of the first component 31 opposite to the junction 33 abuts against the air discharge frame 1, and an end of the second component 32 opposite to the junction 33 abuts against the base 2.
-
For example, as shown in FIG. 1, the evaporator 3 may be a split structure. According to different extension directions, the evaporator 3 may be generally divided into two portions, namely the first component 31 and the second component 32. Both the first component 31 and the second component 32 may be generally flat-plate structures. The first component 31 is generally arranged obliquely along a direction from upper-front to lower-rear, and the second component 32 is generally arranged obliquely along a direction from upper-rear to lower-front. A bottom end of the first component 31 may be lapped with or abutted against a bottom end of the second component 32, and a connection position between the bottom end of the first component 31 and the bottom end of the second component 32 forms the junction 33 between the first component 31 and the second component 32. Specifically, the first component 31 and the second component 32 are generally V-shaped, and the junction 33 between the first component 31 and the second component 32 may protrude downward.
-
The air discharge frame 1 may be located above the first component 31. An upper-front end of the first component 31 may abut against a bottom side of the air discharge frame 1. The base 2 may be arranged vertically and located at a rear side of the evaporator 3. The upper-rear end of the evaporator 3 may abut against a front side surface of the base 2.
-
In the air-conditioner indoor unit according to the embodiments of the present invention, the evaporator 3 is arranged in a two-fold form, so that an internal structure of the air-conditioner indoor unit is relatively simple, an air flow path is short and direct, so that a space for air flow is relatively large, which avoids a situation where a complex structure leads to a tight internal space and affects air intake, reduces the possibility of dust accumulation, lowers the overall air resistance and the workload of a fan, and also reduces the energy consumption ratio of an air conditioner and the user's usage cost, thereby achieving the effects of improving air volume and reducing noise.
-
Secondly, since the overall structure of the evaporator 3 is simpler, the airflow may blow evenly over all parts of the evaporator 3, thus avoiding dead zones that may exist in a complex structure, and further avoiding a situation where insufficient heat exchange in certain areas of the evaporator 3 affects the overall performance of the air conditioner.
-
In some embodiments, the air-conditioner indoor unit includes a panel 6. The panel 6 is arranged opposite to the base 2, and the evaporator 3 is arranged between the panel 6 and the base 2. The panel 6 is arranged obliquely and located below the air discharge frame 1. A distance between the panel 6 and the base 2 gradually decreases in a direction from top to bottom, i.e., in an up-to down direction.
-
For example, as shown in FIG. 1, the panel 6 may be arranged at the front side of the air-conditioner indoor unit. The panel 6 and the base 2 are arranged opposite to each other in a front-rear direction. The evaporator 3 may be arranged in a space between the panel 6 and the base 2.
-
The panel 6 is generally arranged obliquely in a direction from upper-front to lower-rear. A top side of the panel 6 may be connected to a front side edge of the air discharge frame 1. Since the panel 6 is arranged obliquely, the distance between the panel 6 and the base 2 gradually decreases in a direction from top to bottom. The oblique arrangement of the panel 6 may serve an avoidance function, thus allowing more airflow discharged from the air outlet 4 to sweep downward, which may increase an air sweeping area.
-
In some embodiments, an included angle, denoted as a, formed between the panel 6 and a vertical direction ranges from 0 degree to 30 degrees. For example, as shown in FIG. 1, the included angle a may be 5 degrees, 10 degrees, 12 degrees, 15 degrees, 20 degrees, 23 degrees, 25 degrees, 28 degrees, 30 degrees, etc.
-
Thus, this not only meets the design requirement for arranging the panel 6 obliquely, but also limits the range of the overall inclination angle of the panel 6, thereby avoiding a situation where a large inclination angle of the panel 6 easily occupies the internal space of the air-conditioner indoor unit, and reserving sufficient internal space for the installation of internal components such as the evaporator 3.
-
In some embodiments, an included angle, denoted as b, between the panel 6 and the first component 31 ranges from 10 degrees to 25 degrees. For example, as shown in FIG. 1, the included angle b may specifically be 10 degrees, 15 degrees, 18 degrees, 20 degrees, 22 degrees, 25 degrees, etc. The included angle b may specifically be an included angle formed between a front side surface of the first component 31 and an outer surface of the panel 6.
-
Therefore, this may allow a sufficient air intake space to be reserved between the panel 6 and the first component 31. When the included angle b is within the above range, air may smoothly enter the first component 31 from the lower air inlet 5 at a relatively gentle angle.
-
In some embodiments, an upper limit of a spacing, denoted as m, between the panel 6 and the first component 31 ranges from 30 mm to 100 mm. For example, as shown in FIG. 1, the spacing m may be regarded as a maximum value of a distance between the panel 6 and the first component 31 in the front-rear direction. The spacing m may specifically be 30 mm, 32 mm, 35 mm, 40 mm, 45 mm, 50 mm, 55 mm, 60 mm, 65 mm, 70 mm, 75 mm, 80 mm, 85 mm, 90 mm, 95 mm, 100 mm, etc.
-
The spacing m and the included angle b described above may be arranged in combination. When the spacing m and the included angle b are within the above ranges, air may smoothly enter an air intake gap between the first component 31 and the panel 6 from the lower air inlet 5 at a relatively gentle angle. During this process, a relatively uniform airflow distribution may be formed on a surface of the first component 31, thus enabling the evaporator 3 to fully exchange heat with the air, ensuring the heat exchange efficiency of the evaporator 3, and improving the cooling or heating effect of the air conditioner.
-
In some embodiments, the first component 31 includes a first segment 311 and a second segment 312 arranged at an included angle. The first segment 311 is arranged between the second segment 312 and the air discharge frame 1. A connection portion between the first segment 311 and the second segment 312 protrudes in a direction away from the base 2.
-
For example, as shown in FIG. 2, the first component 31 may be a split structure, which includes two independent segments, namely the first segment 311 and the second segment 312. Both the first segment 311 and the second segment 312 are generally arranged obliquely in a direction from upper-front to the lower-bottom. An inclination angle of the first segment 311 is greater than an inclination angle of the second segment 312. A bottom end of the first segment 311 and a top end of the second segment 312 may be directly butted together to form the connection portion, and the formed connection portion may protrude forward.
-
Therefore, this may allow the first component 31 to have a tendency to bend inward towards an interior of the air-conditioner indoor unit, which may to some extent reduce the overall dimension of the first component 31 in the front-rear direction, thus helping to reduce the overall dimension of the air-conditioner indoor unit in the front-rear direction. Secondly, it also facilitates processing and production, and is beneficial to improving the flexibility for fine-tuning the installation angle during installation.
-
In some embodiments, an included angle, denoted as c, between the first segment 311 and the second segment 312 ranges from 140 degrees to 180 degrees. For example, as shown in FIG. 2, the included angle c may be 140 degrees, 145 degrees, 150 degrees, 155 degrees, 160 degrees, 165 degrees, 170 degrees, 175 degrees, 180 degrees, etc.
-
When the included angle c is within the above angle range, on one hand, this may allow the first component 31 formed by the first segment 311 and the second segment 312 to be relatively flat overall, which helps to simplify the overall structural complexity, and also eliminate heat exchange dead corners, thus ensuring uniform heat exchange across all parts. On the other hand, this also meets the design requirement for fine-tuning the angular bending of the first component 31.
-
In some embodiments, an included angle, denoted as d, between the first segment 311 and the panel 6 ranges from 10 degrees to 45 degrees. For example, as shown in FIG. 2, the included angle d may specifically be an included angle formed between a front side surface of the first segment 311 and a front surface of the panel 6. The included angle d may specifically be 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees, etc.
-
When the included angle d is within the above angel range, this may allow a sufficient air intake gap to be reserved between the first segment 311 and the panel 6, thereby ensuring that air may flow to the first segment 311 relatively evenly and stably, and ensuring the heat exchange efficiency and heat exchange uniformity of the first segment 311.
-
In some embodiments, an upper limit of a spacing, denoted as n, between the second component 32 and the base 2 ranges from 25 mm to 100 mm. For example, as shown in FIG. 1, the spacing n may be regarded as a maximum value of a distance between the second component 32 and the base 2 in the front-rear direction. The spacing n may specifically be 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, 55 mm, 60 mm, 65 mm, 70 mm, 75 mm, 80 mm, 85 mm, 90 mm, 95 mm, 100 mm, etc.
-
Thereby, a sufficient air intake gap between the second component 32 and the base 2 is ensured, thus fully meeting the heat exchange requirement of the air flowing from the air inlet 5 to the second component 32.
-
In some embodiments, an included angle, denoted as e, formed between the first component 31 and the second component 32 ranges 55 degrees to 90 degrees. For example, as shown in FIG. 1, the included angle e may specifically be an included angle formed between a rear wall surface of the first component 31 and a front wall surface of the second component 32. The included angle e may specifically be 55 degrees, 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees, 85 degrees, 90 degrees, etc.
-
When the included angle e is within the above range, air may smoothly enter and exit the evaporator 3 for heat exchange, which, at same time, facilitates the smooth drainage of condensate water along the evaporator 3 under gravity. The guiding effect of the evaporator 3 may reduce the risk of water leakage of the air conditioner. A water collection tray or the like for receiving condensate water may be provided at a bottom of the evaporator 3.
-
In some embodiments, an included angle, denoted as f, formed between the second component 32 and the base 2 ranges 25 degrees to 45 degrees. For example, as shown in FIG. 1, the included angle f may be an included angle formed between a rear wall surface of the second component 32 and a front vertical side wall of the base 2. The included angle f may be 25 degrees, 28 degrees, 30 degrees, 32 degrees, 35 degrees, 38 degrees, 40 degrees, 42 degrees, 45 degrees, etc.
-
The included angle f may be designed in combination with the aforementioned spacing n. When the spacing n and the included angle f are within the above ranges, air may smoothly enter the air intake gap between the second component 32 and the base 2 from the lower air inlet 5 at a relatively gentle angle. During this process, a relatively uniform airflow distribution may be formed on a surface of the second component 32, so that the evaporator 3 may fully exchange heat with the air, thus ensuring the heat exchange efficiency of the evaporator 3, and improving the cooling or heating effect of the air conditioner.
