Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically to a drainage base plate and its air conditioner. Background Technology

[0002] When an air conditioner outdoor unit is used outdoors, rainwater can easily seep into the unit through various gaps. Alternatively, after the heat exchanger of the outdoor unit defrosts, the water melted on the surface of the copper pipes will precipitate out in the fins and fall down to the base plate, causing various wastewaters to accumulate in the casing of the outdoor unit. Therefore, a drainage channel is usually installed on the base plate of the air conditioner outdoor unit so that the accumulated water in the base plate can be discharged to the outside by gravity.

[0003] However, existing base plates are usually made of rectangular sheet metal through stamping, and the drainage channels on the base plate are fixed in position and limited in number. Since water often drips from random locations above the outdoor unit, water droplets can be drained smoothly when they fall near the drainage channels; however, if the droplets fall far from the drainage channels, they are difficult to collect in time, which can easily cause local water accumulation on the base plate and thus affect the service life of the outdoor unit. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a drainage base plate and its air conditioner to solve the problem that the drainage channel of the air conditioner outdoor unit base plate is fixed in the existing technology, which easily leads to random water drop points and difficulty in timely collection and drainage of water.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drainage base plate, comprising:

[0007] The base plate body is equipped with a drainage outlet;

[0008] The first drainage channel includes a first water receiving part and a first drainage part connecting the first water receiving part and the drainage outlet;

[0009] The second drainage channel includes a second water inlet and a second drainage section connecting the second water inlet and the drain outlet;

[0010] The first drainage channel and the second drainage channel are located on both sides of the drainage outlet, and form the outer ring of the waterway through the drainage outlet;

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By setting up a first drainage channel and a second drainage channel on both sides of the drain outlet to form an outer ring of waterways, the water accumulated on the bottom slab can be effectively guided to the drain outlet, improving the water collection efficiency. At the same time, a third drainage channel is set up inside the outer ring of the waterways and connected to the first drainage section, so that some water that is not collected by the outer ring in time can still be further guided to the drain outlet through the third drainage channel, thereby further improving the overall drainage effect and preventing local water accumulation on the bottom slab.

[0014] Furthermore, the first water receiving part includes a first drainage slope and a second drainage slope connected together, the second drainage slope being connected to the first drainage part; wherein, the slope of the first drainage slope is greater than the slope of the second drainage slope.

[0015] Furthermore, the first drainage section includes a first drainage channel extending downward at an incline toward the drainage outlet, the first drainage channel being connected to the second drainage ramp for draining water into the drainage outlet.

[0016] Furthermore, the second water receiving part includes a connected third drainage slope and a fourth drainage slope, wherein the fourth drainage slope is connected to the second drainage part; wherein the slope of the third drainage slope is greater than the slope of the fourth drainage slope.

[0017] Furthermore, a guide step is provided at the junction of the fourth drainage slope and the second drainage section, the guide step being used to divert water in the fourth drainage slope to the second drainage section.

[0018] Furthermore, the second drainage section includes a second drainage channel extending downward at an incline toward the drainage outlet, the second drainage channel being connected to the fourth drainage ramp for draining water toward the drainage outlet.

[0019] Furthermore, the third drainage channel includes a water intake section, a converging section, and a reversing section connected in sequence, wherein the reversing section is connected to the first drainage channel; wherein, from the water intake section to the first drainage channel, the third drainage channel extends downward at an angle.

[0020] Furthermore, both the first drainage section and the second drainage section have V-shaped cross-sections.

[0021] Furthermore, the base plate body is provided with a main drainage channel, and the drainage outlet is opened on the main drainage channel. Drainage steps are provided at the joints of the first drainage section and the second drainage section with the main drainage channel. The drainage steps are used to guide the water in the first drainage section and the second drainage section to the main drainage channel.

[0036] Example 1

[0037] like Figure 1-4 As shown, this utility model embodiment proposes a drainage base plate, including a base plate body 1 with a drainage outlet 11; a first drainage channel 2, including a first water receiving part 21 and a first drainage part 22 connecting the first water receiving part 21 and the drainage outlet 11; a second drainage channel 3, including a second water receiving part 31 and a second drainage part 32 connecting the second water receiving part 31 and the drainage outlet 11; wherein, the first drainage channel 2 and the second drainage channel 3 are respectively located on both sides of the drainage outlet 11, and form a waterway outer ring through the drainage outlet 11; a third drainage channel 4 is located inside the waterway outer ring and is connected to the first drainage part 22.

[0038] In this embodiment of the invention, by setting a first drainage channel 2 and a second drainage channel 3 on both sides of the drain outlet 11 to form an outer ring of water channels, the water accumulated on the bottom plate can be effectively guided to the drain outlet 11, improving the water collection efficiency. Simultaneously, a third drainage channel 4 is set inside the outer ring of the water channels and connected to the first drainage section 22, allowing some water that is not collected by the outer ring to be further guided to the drain outlet 11 through the third drainage channel 4, thereby further improving the overall drainage effect and preventing localized water accumulation on the bottom plate. The outer ring of the water channels is mainly used to collect rainwater seeping into the gaps in the sheet metal of the air conditioner casing, or other wastewater falling near the outside; while the third drainage channel 4 inside the outer ring is mainly used to collect water falling from the heat exchanger fins of the air conditioner outdoor unit.

[0039] Specifically, such as Figure 2As shown in this embodiment of the invention, the first water receiving part 21 includes a first drainage slope 211 and a second drainage slope 212 connected together, with the second drainage slope 212 connected to the first drainage part 22; and the slope of the first drainage slope 211 is greater than the slope of the second drainage slope 212. Water can be quickly drained into the first drainage part 22 via the first drainage slope 211 and then guided to the drain outlet 11 by the first drainage part 22, thus achieving rapid drainage. The slopes of the first drainage slope 211 and the second drainage slope 212 are adapted to the amount of water accumulated at that location, ensuring a steeper slope where the water volume is high and a gentler slope where the water volume is low, thereby better facilitating drainage.

[0040] Specifically, such as Figure 2 As shown in the embodiment of this utility model, the first drainage section 22 includes a first drainage channel 221 extending downward towards the drain outlet 11. The first drainage channel 221 is connected to the second drainage slope 212 and is used to drain water into the drain outlet 11, thereby smoothly guiding the accumulated water collected in the first drainage channel 221 to the drain outlet 11 and realizing timely drainage.

[0041] Specifically, such as Figure 2 As shown in this embodiment of the invention, the second water receiving part 31 includes a connected third drainage slope 311 and a fourth drainage slope 312. The fourth drainage slope 312 is connected to the second drainage part 32 and is mainly used to collect wastewater falling from the bottom of the compressor. The slope of the third drainage slope 311 is greater than that of the fourth drainage slope 312. The third drainage slope 311 allows the accumulated water to quickly flow into the second drainage part 32 through the fourth drainage slope 312, and then the second drainage part 32 guides the accumulated water to the drain outlet 11, thereby achieving rapid drainage. The slope of the third drainage slope 311 and the fourth drainage slope 312 is adapted to the amount of water accumulated at that location, ensuring that the slope is larger where the water volume is large and smaller where the water volume is small, so as to better achieve drainage.

[0042] Specifically, such as Figure 3 As shown in this embodiment of the invention, a guide step 33 is provided at the joint between the fourth drainage slope 312 and the second drainage section 32. The guide step 33 is used to divert water from the fourth drainage slope 312 to the second drainage section 32. By providing the guide step 33, the accumulated water in the fourth drainage slope 312 can be quickly diverted to the second drainage section 32, improving drainage efficiency and avoiding stagnation, thus further ensuring smooth drainage. At the same time, providing the guide step 33 also further enhances the structural strength of the joint.

[0043] Specifically, such as Figure 2 As shown in the embodiment of this utility model, the second drainage section 32 includes a second drainage channel 321 extending downward at an incline toward the drainage outlet 11. The second drainage channel 321 is connected to the fourth drainage slope 312 and is used to drain water into the drainage outlet 11, thereby smoothly guiding the accumulated water collected in the second drainage channel 321 to the drainage outlet 11 and realizing timely drainage.

[0044] Specifically, such as Figure 2 As shown in this embodiment of the present invention, the third drainage channel 4 is positioned directly below the heat exchanger fins of the outdoor unit of the air conditioner, and is used to collect a large amount of water that falls and overflows from the fins; specifically, the third drainage channel 4 includes a water-guiding section 41, a gathering section 42, and a reverse section 43 connected in sequence, and the reverse section 43 is connected to the first drainage channel 221; wherein, the water-guiding section 41, the gathering section 42, and the reverse section 43 are all inclined downwards. Specifically, the water intake section 41, as the initial section, is located far from the main drain outlet 11 to ensure a large initial velocity of the water flow. The width of the water intake section 41 gradually increases from one end near the converging section 42 to the other, effectively collecting more accumulated water and guiding it into the converging section 42, thereby improving overall drainage efficiency. Its slope is preferably 2.5 degrees to balance flow velocity and water collection efficiency. The converging section 42, as the middle section, gradually narrows its cross-section, further concentrating the incoming water flow, thereby increasing flow velocity and improving overall drainage efficiency. Its slope is preferably 1.3 degrees. The reverse section 43, as the end section, has a reverse slope, preferably 1.4 degrees. By forming a certain reverse slope at this location, the flow velocity of the water entering the corner can be effectively reduced, avoiding turbulence caused by high-speed impact, thus ensuring the stability of the water flow at the bend and the continuity of drainage.

[0045] It is worth mentioning that the reverse section 43 can be connected to the first drainage channel 221 alone, or to the second drainage channel 321 alone, or to both the first drainage channel 221 and the second drainage channel 321 at the same time. It is adapted to the installation position of the components on the drainage base plate to ensure that the water generated by the heat exchanger fins or other components of the air conditioner outdoor unit can be effectively guided to the drain outlet 11.

[0046] Specifically, in this embodiment of the invention, both the first drainage section 22 and the second drainage section 32 have V-shaped cross-sections. By designing the first drainage section 22 and the second drainage section 32 with V-shaped cross-sections, the situation where water spreads out in the waterway and its flow velocity decreases due to surface tension, which is common with planar structures, can be effectively avoided. Conversely, the V-shaped cross-section allows water to concentrate and quickly flow into the main drainage channel 5 under the converging effect at the structural tip, thereby improving overall drainage efficiency and avoiding drainage stagnation.

[0047] Preferably, the included angle of the V-shaped cross-section is 1.8 degrees. This angle ensures smooth water collection while preventing water dispersion due to an excessively large angle or blockage due to an excessively small angle. The V-shaped cross-section can be formed in one piece or by splicing two plates, with its pointed end facing downwards. This allows water to naturally converge and flow into the downstream main drainage channel 5, achieving a more efficient drainage effect.

[0048] Specifically, such as Figure 4 As shown in this embodiment of the invention, the base plate body 1 is provided with a drainage channel, and the drainage outlet 11 is opened on the drainage channel. Drainage steps 51 are provided at the joints of the first drainage section 22 and the second drainage section 32 with the drainage channel. The drainage steps 51 are used to guide the water in the first drainage section 22 and the second drainage section 32 to the drainage channel. By providing the drainage steps 51, the accumulated water in the first drainage section 22 and the second drainage section 32 can be quickly guided to the drainage channel so that the drainage outlet 11 can drain the water, improving drainage efficiency and avoiding stagnation, further ensuring smooth drainage. At the same time, by providing the drainage steps 51, the structural strength of the joint can also be further improved.
