[0032] The embodiments of the present application are described in detail below, examples of which are shown in the drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.
[0033] The indoor unit of the embodiment of the present application can be a wall-mounted indoor unit, and the indoor unit is provided with an air inlet 4 and an air outlet 3 located above the air inlet 4, for example, as shown in Figure 1 The air inlet 4 can be arranged at the bottom side of the indoor unit, and the air outlet 3 can be located at the top of the front side of the indoor unit.
[0034] As shown in Figure 1 The indoor unit includes a base 1 and an evaporator 2, and the base 1 can be arranged at the rear side of the evaporator 2, and the base 1 can be arranged vertically. The material of the base 1 can be plastic, metal, etc.
[0035] The evaporator 2 includes a first component 21 and a second component 22 arranged at an angle, and the joint 23 of the first component 21 and the second component 22 protrudes towards the air inlet 4, and the second component 22 is located between the base 1 and the first component 21, and the second component 22 abuts against the base 1.
[0036] For example, as shown in Figure 1 The evaporator 2 can be divided into two parts, and the two parts are the first component 21 and the second component 22, and the first component 21 and the second component 22 can be generally flat structures, wherein the first component 21 can be arranged inclined along the direction from front to bottom to back, and the second component 22 can be arranged inclined along the direction from back to bottom to front.
[0037] The bottom end of the first component 21 and the bottom end of the second component 22 can be overlapped or abuttingly contacted, and the connecting position of the bottom end of the first component 21 and the bottom end of the second component 22 forms the joint 23 of the two components. Specifically, the first component 21 and the second component 22 are generally V-shaped, and the joint 23 of the first component 21 and the second component 22 can protrude downward, and the air inlet 4 can be located directly below the joint 23.
[0038] As shown in Figure 1As shown, along the front-to-back direction, the first component 21 can be roughly located on the front side of the second component 22, and the base 1 can be roughly located on the rear side of the second component 22. The top end of the second component 22 can abut against the inner wall surface of the base 1, thereby ensuring the structural stability of the assembly of the second component 22.
[0039] The base 1 has a vertical surface 11 and an inclined surface 12 facing the second component 22, wherein the inclined surface 12 is located below the vertical surface 11. A portion of the inner wall surface of the base 1 can be arranged in an inclined direction from the upper rear to the lower front, and this portion of the inclined inner wall surface forms the inclined surface 12. The inclined surface 12 can be located on the rear side of the second component 22 and spaced apart from the second component 22.
[0040] The included angle a between the second component 22 and the vertical surface 11 of the base 1 is 25 to 45 degrees. Figure 1 As shown, part of the inner wall surface of the base 1 can be arranged vertically and form a vertical surface 11. The angle a can be regarded as the angle formed by the vertical surface 11 and the rear wall surface of the second component 22. The angle a can specifically be 25 degrees, 28 degrees, 30 degrees, 32 degrees, 35 degrees, 38 degrees, 40 degrees, 42 degrees, 44 degrees, 45 degrees, etc.
[0041] In some embodiments, the second component 22 and the inclined surface 12 form an angle b, and the angle b is 5 degrees to 40 degrees. Figure 1 As shown, the angle b can be the angle formed by the rear wall surface of the second component 22 and the inclined surface 12. The angle b can be 5 degrees, 7 degrees, 8 degrees, 10 degrees, 12 degrees, 15 degrees, 18 degrees, 20 degrees, 24 degrees, 25 degrees, 28 degrees, 30 degrees, 32 degrees, 35 degrees, 38 degrees, 40 degrees, etc.
[0042] In some embodiments, the lower limit of the distance h between the inclined surface 12 and the second component 22 is 8 mm to 50 mm. For example, the lower limit of the distance h can be regarded as the minimum distance between the inclined surface 12 and the second component 22 in the front-to-back direction, and the minimum distance can be 8 mm, 9 mm, 10 mm, 12 mm, 15 mm, 18 mm, 20 mm, 25 mm, 28 mm, 30 mm, 35 mm, 38 mm, 40 mm, 42 mm, 45 mm, 48 mm, 50 mm, etc.
[0043] In the indoor unit of the air conditioner of the embodiment of the present invention, the evaporator 2 is arranged in a two-fold form, so that the internal structure of the indoor unit of the air conditioner is relatively simple, the air circulation path is short and direct, and the space for air circulation is relatively large, thereby avoiding the situation where the internal space is tight due to a complex structure and the air intake is affected, reducing the possibility of dust accumulation, and also reducing the overall wind resistance and the workload of the fan, and also reducing the energy consumption ratio of the air conditioner and the user's cost of use, thereby improving the air volume and reducing noise.
[0044] Secondly, due to the simple overall structure of the evaporator 2, the air flow can uniformly blow through each part of the evaporator 2, avoiding the situation of dead angle existing when the structure is complex, and further avoiding the situation that the heat exchange of some areas of the evaporator 2 is insufficient, which affects the performance of the air conditioning unit.
[0045] In addition, by limiting the included angle a between the second component 22 and the vertical surface 11 of the base 1 within the above range, while achieving the compactness of the structural arrangement, the use needs of the air flowing into the second component 22 and the base 1 relatively uniformly and then flowing through the second component 22 for heat exchange are also met, thereby ensuring the air supply amount of the second component 22 during operation.
[0046] The included angle a within the above range can also make the overall structure of the air conditioning indoor unit more compact, occupy less space, and make the air flow in the air conditioning indoor unit more smooth, thereby improving the overall circulation effect of the air and the comfort of the user.
[0047] In some embodiments, the angle of the included angle b is smaller than the angle of the included angle a.
[0048] As shown in Figure 1 , the angle of the included angle b is overall smaller than the angle of the included angle a. Thus, the space gap between the vertical surface 11 and the second component 22 can be increased, the space gap between the inclined surface 12 and the second component 22 and the size difference of the space gap between the vertical surface 11 and the second component 22 can be reduced, thereby enabling more air to flow to the top of the second component 22, and fully ensuring the heat exchange effect of the top of the second component 22.
[0049] In some embodiments, the angle of the included angle b is 8 degrees to 35 degrees. For example, as shown in Figure 1 , the included angle b can be 8 degrees, 10 degrees, 12 degrees, 15 degrees, 18 degrees, 20 degrees, 24 degrees, 25 degrees, 28 degrees, 30 degrees, 32 degrees, 35 degrees, etc.
[0050] The included angle b within the above angle range not only achieves the compactness of the structural arrangement, but also fully meets the use needs of the air supply to the second component 22, thereby ensuring the overall heat exchange effect and efficiency of the second component 22.
[0051] In some embodiments, the vertical surface 11 and the inclined surface 12 are connected through the connecting surface 13, for example, as shown in Figure 1As shown, the connecting surface 13 can also be inclined, and the connecting surface 13 can also be arranged in an inclined manner along the rear-to-front and upper-to-lower direction. Since the inclination angle of the connecting surface 13 is relatively gentle, the distance between the connecting surface 13 and the second component 22 can be substantially constant, thereby facilitating the air flow between the connecting surface 13 and the second component 22 into the vertical surface 11 and the second component 22, further ensuring the air supply amount to the top end of the second component 22, thereby further ensuring the uniformity of heat exchange, and avoiding the problem of poor heat exchange in local areas.
[0052] In some embodiments, the lower limit value of the distance h between the inclined surface 12 and the second component 22 is 10 mm to 45 mm. For example, the minimum distance h can be 10 mm, 12 mm, 15 mm, 18 mm, 20 mm, 25 mm, 28 mm, 30 mm, 35 mm, 38 mm, 40 mm, 42 mm, 45 mm, etc.
[0053] By limiting the minimum size of the distance h, on the one hand, the distance between the base 1 and the second component 22 can be prevented from being too large, thereby ensuring the compactness of the structure arrangement, and on the other hand, the distance between the base 1 and the second component 22 can be prevented from being too small to affect the air supply amount, thereby ensuring the heat exchange effect of the second component 22.
[0054] In some embodiments, as shown in FIG. 1, Figure 1 The distance h between the inclined surface 12 and the second component 22 gradually decreases along the lower-to-upper direction, and the distance h between the top side edge of the inclined surface 12 and the second component 22 forms a lower limit value. Thus, the use requirement of supplying sufficient air to the second component 22 is fully met.
[0055] In some embodiments, the upper limit value of the distance n between the second component 22 and the base 1 is 25 mm to 100 mm. For example, as shown in FIG. 1, Figure 1 The distance n can be regarded as the maximum value of the distance between the second component 22 and the base 1 in the front-to-rear direction, and specifically can be the distance between the bottom end of the second component 22 and the inclined surface 12. The distance n can be specifically 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, 55 mm, 65 mm, 75 mm, 85 mm, 95 mm, 100 mm, etc.
[0056] Thus, the sufficient air inlet gap between the second component 22 and the base 1 is ensured, thereby fully meeting the use requirement of the air flow at the air inlet 4 to the second component 22 for heat exchange.
[0057] In some embodiments, the included angle c formed by the first component 21 and the second component 22 is 55 degrees to 90 degrees. For example, as shown in FIG. 1, Figure 1As shown, the included angle c can be specifically the included angle formed by the rear wall surface of the first component 21 and the front wall surface of the second component 22. The included angle c can be 55 degrees, 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees, 85 degrees, 90 degrees, etc.
[0058] The included angle c is within the above range, so that the air in this interval can smoothly enter and exit the evaporator 2 for heat exchange, and at the same time, the condensed water can be smoothly discharged along the evaporator 2 under the action of gravity. The drainage function of the evaporator 2 can reduce the risk of air conditioner water leakage, and the bottom of the evaporator 2 can be provided with a water receiving tray 6 or the like for receiving condensed water.
[0059] In some embodiments, the air conditioner indoor unit includes a panel 5, and the first component 21 is arranged between the panel 5 and the second component 22, for example, as shown in Figure 1 As shown, the panel 5 can be arranged on the front side of the first component 21, and the second component 22 can be arranged behind the first component 21. The panel 5 can play an external decoration role in use, ensuring the appearance.
[0060] In some embodiments, the upper limit value of the spacing m between the panel 5 and the first component 21 is 30mm to 100mm. For example, as shown in Figure 1 As shown, the spacing m can be regarded as the maximum value of the spacing of the panel 5 and the first component 21 in the front-rear direction, and the spacing m can be specifically 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 90mm, 95mm, 100mm, etc.
[0061] In some embodiments, the included angle d formed by the panel 5 and the first component 21 is 10 degrees to 25 degrees. For example, as shown in Figure 1 As shown, the included angle d can be specifically 10 degrees, 15 degrees, 18 degrees, 20 degrees, 22 degrees, 25 degrees, etc. The included angle d can be the included angle formed between the front side of the first component 21 and the outer surface of the panel 5.
[0062] The spacing m and the above-mentioned included angle d can be arranged in combination. When the spacing m and the included angle d are within the above range, the air can smoothly enter the air inlet gap between the first component 21 and the panel 5 from the lower air inlet 4 at a relatively gentle angle, and in this process, the surface of the first component 21 can form a relatively uniform air flow distribution, so that the evaporator 2 can fully exchange heat with the air, ensuring the heat exchange efficiency of the evaporator 2, thereby improving the refrigeration or heating effect of the air conditioner.
[0063] The air conditioning system of the embodiments of the present application is described below.
[0064] The air conditioning system in the embodiment of the present application comprises an air conditioning indoor unit, which can be the air conditioning indoor unit described in any of the above embodiments, and can specifically be an air conditioning hanging unit. The air conditioning system can further comprise an air conditioning outdoor unit and the like.
[0065] Although the above embodiments have been shown and described, it can be understood that the above embodiments are exemplary and cannot be understood as limiting the present application, and the changes, modifications, replacements and variations of the above embodiments made by those of ordinary skill in the art are within the protection scope of the present application.
