Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning equipment, in particular to an air-conditioning outdoor unit and a drainage structure thereof. Background Art

[0002] The air conditioner will produce condensation during the heating and defrosting operations, and the condensation water is generally discharged from the drain hole at the bottom of the air conditioner outdoor unit.

[0003] The drainage hole at the bottom of the existing air conditioner outdoor unit is generally designed as a circular hole with a small inner diameter, and the water nozzle matched with the circular drainage hole is also small. If the condensed water flow is large, the drainage may not be timely, which will affect the reliability of the air conditioner operation process. When the outdoor temperature is low (such as the outdoor temperature is below zero), the water outlet of the chassis will be frozen and unable to continue to drain. In severe cases, the ice layer will thicken, and even the fan blades will collide with the ice layer and break. Summary of the invention

[0004] In order to solve the above problems, the purpose of the utility model is to provide an air-conditioning outdoor unit and a drainage structure thereof.

[0005] A drainage structure for an air conditioner outdoor unit comprises a chassis of the air conditioner outdoor unit, wherein the chassis is arranged at an inclination, a main drainage outlet is arranged at the lowest position of the chassis, and the main drainage outlet is located in a negative pressure area of ​​a fan wind field in the air conditioner outdoor unit; a plurality of auxiliary drainage outlets are also arranged on the chassis, the positions of the auxiliary drainage outlets are higher than the main drainage outlets, and the auxiliary drainage outlets are located in a positive pressure area of ​​the fan wind field in the air conditioner outdoor unit.

[0006] As a preselection, the main drain outlet is oval or waist-shaped, and its long axis is arranged parallel to the long side of the bottom plate.

DETAILED DESCRIPTION

[0031] The embodiments of the present utility model are described in detail below.

[0032] This embodiment provides a drainage structure of an outdoor unit of an air conditioner, such as Figure 1 As shown, the main parts of the air conditioner outdoor unit chassis 1 and the water outlet nozzle 2 are improved.

[0033] The chassis 1 structure of the air conditioner outdoor unit is as follows Figure 2-5 As shown, the chassis 1 is provided with two types of drain outlets, namely, a main drain outlet 101 and an auxiliary drain outlet 102. The bottom of the chassis 1 is tilted to one side as a whole. The main drain outlet 101 is arranged at the lowest position of the chassis 1, so that the accumulated water on the chassis 1 can flow to the main drain outlet 101 under the guidance of the slope of the chassis 1. The auxiliary drain outlet 102 is located above the slope relative to the main drain outlet 101, and the auxiliary drain outlet 102 is located in the positive pressure area of ​​the fan wind field in the outdoor unit of the air conditioner, so that the positive pressure of the fan can be used to cause the water on the chassis 1 to flow out from the auxiliary drain outlet 102. In other embodiments, the bottom plate has an arc slope, the main drain outlet 101 is located at the lowest end of the arc slope of the bottom plate, and the auxiliary drain outlet 102 is located at the high position of the arc slope of the chassis 1. The above-mentioned slope or arc slope is set to form a diversion to the main drain outlet 101 by using the slope of the chassis 1 itself.

[0034] Preferably, the main drain port 101 is elliptical or waist-shaped, and its long axis is arranged parallel to the long side of the chassis 1, so as to increase the opening size of the main drain port 101 as much as possible and increase the drainage volume.

[0035] Combination Figure 5As shown, the main drain port 101 protrudes toward the bottom of the base plate, and the connection 1011 between the main drain port and the base plate is transitioned by an inclined surface. This arrangement can prevent wastewater entering the main drain port 101 from accumulating at the connection between the main drain port 101 and the base plate 1, making it easier to discharge wastewater.

[0036] The structure of the water outlet 2 is as follows: Figure 6-Figure 8 As shown, the main drain port 101 is connected to the drain pipe through the water outlet 2 to drain water outward. Fig. 9 As shown, in this embodiment, the water outlet 2 and the main drain outlet 101 are detachably connected by a buckle 202 structure, which is convenient for disassembly and assembly. Specifically, the water outlet 2 includes at least one pair of buckles 202 extending upward, and the upper ends of the buckles 202 form an inverted first limit portion 2021. After the water outlet 2 is installed in place on the main drain outlet 101, the first limit portion 2021 is located above the main drain outlet 101 and abuts against the chassis 1. In this embodiment, as shown in FIG. Figure 5 and Figure 6 As shown, it includes a pair of buckles 202 symmetrically arranged along the short axis of the main drain outlet 101, and the first limiting portion 2021 at the upper end of the buckle 202 cooperates with the bottom plate 1 to limit the downward movement of the water outlet 2. The support rod of the buckle 202 is a slightly deformable material, such as a thin material. When squeezed by an external force, the pair of buckles 202 can be close to each other so that they can extend upward from the main drain outlet 101 from the bottom, and after the external force is removed, the pair of buckles 202 are reset to achieve the limitation of the first limiting portion 2021. In other embodiments, the pair of buckles 202 can also be set at other positions along the opening contour of the main drain outlet 101.

[0037] In an optional embodiment, a second limiting portion 2022 is formed on the support rod of the buckle 202, which is arranged opposite to the first limiting portion 2021. After the water outlet 2 is installed in place on the main drain outlet 101, the second limiting portion 2022 abuts against the lower end of the main drain outlet 101. The second limiting portion 2022 cooperates with the chassis 1 to limit the upward movement of the water outlet 2, thereby limiting the water outlet 2 in the up and down directions through the first limiting portion 2021 and the second limiting portion 2022. Optionally, the water outlet 2 is provided with a plurality of support platforms 203 arranged corresponding to the outer contour of the opening of the main drain outlet 101. After the water outlet 2 is installed in place on the main drain outlet 101, the support platform 203 abuts against the lower end of the main drain outlet 101. Thus, the downward direction of the water outlet 2 can also be limited by the support platform 203. For the specific positional relationship between the first limiting portion 2021, the second limiting portion 2022 and the main drain outlet 101 in this embodiment, refer to Fig.10 shown.

[0038] In addition, Figure 6 and Figure 7As shown, the water outlet 2 is also provided with a third limiting portion 204. After the water outlet 2 is installed in place, the third limiting portion 204 is closely attached to the outer side of the outer peripheral wall of the opening end of the main drain outlet 101, so as to limit the radial and circumferential positions of the water outlet 2. The positional relationship between the third limiting portion 204 and the main drain outlet 101 is specifically referred to Fig.11 Optionally, in an embodiment where a pair of buckles 202 are symmetrically arranged along the short axis of the main drain port 101 , a pair of third limiting portions 204 are symmetrically arranged along the long axis of the water outlet 2 , thereby limiting the water outlet 2 in radial and circumferential directions.

[0039] Furthermore, the water outlet 2 includes a circle of upwardly turned water retaining edge 205, and the water retaining edge 205 is located outside the support platform 203. The arrangement of the water retaining edge 205 can prevent the waste water discharged from the main drain port 101 from leaking at the connection between the water outlet 2 and the main drain port 101.

[0040] Therefore, the water supply and drainage structure can realize auxiliary drainage through the auxiliary drainage outlet 102 when the drainage function of the main drainage outlet 101 is limited, and the connection structure between the water outlet 2 and the main drainage outlet 101 is convenient and reliable.

[0041] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
