Referring to fig. 1-7, the disclosed embodiments provide a drainage structure including a drainage plate 1, a drainage groove 2, and a flow guide 3. The drainage plate 1 is used for being connected with an air outlet 5 of the air duct 4, and the drainage plate 1 is obliquely arranged; the current collection groove 2 with drainage plate 1 is connected, water conservancy diversion piece 3 set up in on the drainage plate 1, be used for with condensate water drainage on the drainage plate 1 extremely in the current collection groove 2. In a use state, the drainage groove 2 is horizontally arranged, and the upper surface of the drainage plate 1 is obliquely arranged relative to the horizontal plane. Specifically, one side that air outlet 5 was kept away from to drainage plate 1 is the downward sloping, for the direction that is located the comdenstion water on drainage plate 1 and provides the water conservancy diversion for the comdenstion water has the effort that flows to current collection groove 2 under the effect of gravity.

In the in-service use process, drainage plate 1 is used for accepting the comdenstion water, and water conservancy diversion piece 3 then plays the effect of gathering and water conservancy diversion to the comdenstion water to flow the comdenstion water to the mass flow groove 2 along the direction of water conservancy diversion piece 3 in, realize the collection effect to the comdenstion water, avoid the comdenstion water to drip subaerially, lead to surface ponding.

Specifically, the top of collecting tank 2 is the opening setting, and drainage plate 1 and open-ended end connection, during comdenstion water accessible opening on the drainage plate 1 flows to collecting tank 2, collecting tank 2 played the function of saving to the comdenstion water. Meanwhile, the arrangement form of the flow collecting groove 2 is not limited by the application, for example, the bottom surface of the inner wall of the flow collecting groove 2 can be arranged in parallel with the horizontal plane, so that the flow collecting groove 2 can collect the condensed water, and the condensed water in the flow collecting groove 2 cannot move under the action that the gravity cannot be applied to the inclined plane. Meanwhile, an included angle can be formed between the bottom surface of the inner wall of the flow collecting groove 2 and the horizontal plane, and the condensed water in the flow collecting groove 2 has a movement trend through the arrangement of the included angle. Alternatively, the water collecting tank 2 in the present application is mainly used for collecting the condensed water. While in other uses, those skilled in the art may configure the header tank 2 in different forms depending on the needs and purposes.

Further, the inner wall of the side wall of the drainage groove 2 far away from the drainage plate 1 is an arc surface. Through the arrangement of the cambered surface, the cleaning in the later period is facilitated.

Further, the drainage plate 1 comprises a first part 6 and a second part 7 which are connected with each other, the first part 6 and the second part 7 are both triangular, and in a plane perpendicular to the extending direction of the collecting groove 2, the included angle between the upper surface of the first part 6 and the horizontal plane is A, and A satisfies: a is more than 0 degree and less than or equal to 5 degrees. Thereby through contained angle A's setting with drainage plate 1 in the use can with form an angle of inclination between the horizontal plane, be convenient for be located the flow of condensation on the drainage plate 1. Specifically, the angle of the inclination angle a of the first portion 6 is not easily too large, and when the angle is too large, the structural building material is affected, so that the thickness of the drainage plate 1 connected with other components is also increased correspondingly, the thickness of the drainage plate 1 is too thick, the material is wasted, the cost is increased, and the drainage plate 1 is not easily connected with other components.

Further, the upper surface of the second portion 7 has an included angle B in a cross section parallel to the extending direction of the chute 2 and perpendicular to the horizontal plane, where B satisfies: b is more than 0 degree and less than or equal to 20 degrees. When the second part 7 is in use, the side edge of the second part 7 at the right side of the second part 7 in the extending direction of the collecting tank 2 inclines towards the side edge at the left side of the second part 7, and the inclined angle is B. The first part 6 and the second part 7 are spliced to form the complete drainage plate 1, and the condensation on the right side of the second part 7 can flow towards the left side of the second part 7 by means of gravity through the arrangement of the included angle B and can flow along the extending direction of the flow guide member 3.

Specifically, be located the nearly horizontally direction of water conservancy diversion spare 3 on the second part 7 extends and arranges, through the mode of setting up of water conservancy diversion spare 3, can play the effect of interception to the condensation, avoids the condensation to be blown out, leads to the collection groove 2 can't collect the condensation.

Further, the length of the side of the first part 6 for connecting with the air outlet 5 is the same as that of the air outlet 5, and the length of the side of the second part 7 for connecting with the collecting groove 2 is the same as that of the collecting groove 2; therefore, condensation generated at the air outlet 5 can flow to the flow collecting groove 2 through the flow guiding plate 1, and the situation that the condensed water drips everywhere is avoided.

Specifically, the included angle of the first portion 6 is the difference between the inclination angles of the drainage plate 1 on both sides in the width direction, and the included angle of the second portion 7 is the difference between the inclination angles of the drainage plate 1 on both sides in the length direction. Therefore, in order to ensure the integrity of the flow guide plate 1, the first and second portions 6 and 7 may be optionally arranged at the same inclination angle on both sides of the flow guide plate 1 in the width direction.

Optionally, the first portion 6 and the second portion 7 are both right triangles, and the first portion 6 and the second portion 7 are spliced with each other to form a rectangle. The edges of the rectangle can realize the stable connection between one of the two ends and other parts, and the other end can be stably connected with the edges of the flow collecting groove 2, so that all the condensed water on the drainage plate 1 can flow into the flow collecting groove 2 to be collected and stored. And through the arrangement of the right triangle, when the second part 7 is inclined, the condensed water can be guided to the direction of one of the corners of the right triangle, so that the condensed water can be collected in a concentrated manner. Likewise, the first portion 6 and the second portion 7 may also take other shape configurations.

Further, the width of the diversion member 3 gradually decreases in the direction close to the flow collecting groove 2, and the diversion member 3 is arranged from wide to narrow, so that the diversion member 3 above is wide in width, the contact area between the diversion member 3 and the condensate water is large, the flowing speed of the condensate water is high, and the drainage effect is improved. Meanwhile, the width of the flow guide piece 3 positioned above is wide, the quantity of received condensed water is large, the adsorption effect on the condensed water is high, and condensed water of small water drops is conveniently condensed into large water drops.

In particular, in order to ensure the drainage effect of the flow guide 3 on the condensate, the flow guide 3 is linear, so that the condensate can flow along the guide direction of the flow guide 3. Simultaneously, because the condensation initial stage volume is few, easily condenses into the difficult landing of drop of water under the effect of water surface tension, can reduce the surface tension effect of water through setting up of water conservancy diversion piece 3, in time collects the condensation that produces to ponding groove.

Optionally, the flow guide member 3 may also be a hydrophobic layer, and the hydrophobic layer is disposed on the drainage plate 1, so as to reduce the surface tension of water on the drainage plate 1, and achieve the flowability of condensed water on the drainage plate 1.

Optionally, the diversion part 3 can also be a siphon device, and the condensate water on the drainage plate 1 is drained to the water collecting tank through the siphon device, so that the drainage effect on the condensate water is realized. The flow guiding member 3 may be disposed in other manners known in the art to reduce the surface tension of the condensed water, so as to further promote the condensed water on the flow guiding plate 1 to flow into the collecting groove 2, which is not listed here.

Furthermore, the flow guide pieces 3 are arranged in a plurality, and each flow guide piece 3 is radially distributed on the drainage plate 1 in the center. Through the radial distribution in center for all there is the setting of water conservancy diversion piece 3 in the arbitrary position on the length direction of drainage plate 1, thereby can realize the interception effect to the comdenstion water, avoid the comdenstion water to be blown out and low fall subaerial. Meanwhile, each flow guide piece 3 is set to be in the shape, so that condensed water is guided to the same position of the flow collecting groove 2 by the flow guide pieces 3, the condensed water is convenient to assemble to form large water drops, and the stability of the condensed water in the flow collecting groove 2 is guaranteed.

In particular, the arrangement of the flow-guiding members 3 on the flow-guiding plate 1 should not be too dense, which increases the water resistance when the flow-guiding members 3 are arranged too densely on the flow-guiding plate 1. The number of flow guides 3 is thus set depending on the area of the flow guide plate 1. For example, the area of the drainage plate 1 provided by the present application is 30cm²In time, the number of the flow guide parts 3 is 4. In actual use, those skilled in the art can make reference to the data provided in the present application.

Further, the number of the flow guide plates 1 is two or more, and the second portion 7 of each flow guide plate 1 is connected to the flow collecting groove 2. At this time, optionally, the length of the whole formed by splicing the drainage plates 1 is the same as that of the water collecting tank, so as to ensure that the condensed water on each drainage plate 1 can flow into the water collecting tank 2. And this application does not do the restriction to the form that sets up of each drainage plate 1, and in the in-service use process, each drainage plate 1 can all arrange in proper order towards same direction, and each drainage plate 1 also can arrange towards different directions simultaneously. For example, when two drainage plates 1 are provided, the length of the whole formed by splicing the two drainage plates 1 is the same as that of the collecting groove 2. Meanwhile, the two drainage plates 1 can be symmetrically arranged, that is, the two drainage plates 1 are arranged towards different directions; the two drainage plates 1 may also be symmetrically disposed, that is, the two drainage plates 1 are arranged facing the same direction.

Further, the drainage port 8 is arranged on the collecting tank 2, so that condensed water in the collecting tank 2 can be conveniently drained through the drainage port 8, and the condition that the condensed water is accumulated in the collecting tank 2 for a long time to cause the collecting tank 2 to be full of the condensed water and overflow is avoided.

In particular, the drainage openings 8 are provided in the side wall of the drainage groove 2 to which the drainage plate 1 is connected. The drainage port 8 is formed in the direction of the flow collecting groove 2 towards the drainage plate 1, so that the opening direction of the drainage port 8 is opposite to the water flow direction of the condensed water, and cold leakage is avoided; or the case where wind blows toward the drain port 8 to cause abnormal noise.

Alternatively, the drainage opening 8 is located in the center of the central radial formed by the flow guides 3. Through setting up the position at the center with drainage port 8 for the position that the collection groove 2 was intake is close to the position that collection groove 2 was gone out water, is convenient for the discharge of the interior condensate water of collection groove 2.

In particular, the drainage ports 8 are provided in two or more. In actual use, the number of drainage ports 8 corresponding to the drainage plate 1 can be selected according to the number and arrangement of the drainage plates 1.

Specifically, the upper and lower positions of the drainage port 8 on the corresponding side wall of the collecting groove 2 are not limited in the present application. For example, the bottom of the drainage opening 8 may be parallel to the bottom of the collecting trough 2, and the collecting trough 2 may provide a transition for the condensed water, so that the condensed water may flow out of the collecting trough 2 through the drainage opening 8 after entering the collecting trough 2. Likewise, the bottom of the drainage opening 8 can also be located above the bottom of the collecting trough 2, so that a height difference is formed between the bottom of the drainage opening 8 and the bottom of the collecting trough 2, the collecting trough 2 can store the condensed water by the height difference, and when the condensed water in the collecting trough 2 is accumulated to a certain height, that is, the height of the upper surface of the condensed water in the collecting trough 2 exceeds the height of the bottom of the drainage opening 8, the condensed water in the collecting trough 2 can be drained out of the collecting trough 2 through the drainage opening 8.

Further, the cross-sectional area of the drainage port 8 in the axial direction thereof is greater than or equal to 1.5mm²Due to the surface tension of water, the area of the opening of the drainage port 8 is too small, which causes condensation to form a film at the drainage port 8, thereby blocking drainage.

Specifically, the cross-section of the discharge port 8 in the axial direction thereof is rectangular, circular, or the like. In order to facilitate the stable outflow of the condensed water from the header tank 2, the cross section of the drain port 8 in the axial direction thereof is preferably regular, such as circular, square or rectangular. Meanwhile, the shapes of triangle, star and the like can be selected according to other requirements.

Further, the distance between the side wall of the collecting groove 2 far away from the air outlet 5 and the air outlet 5 is greater than or equal to 20 mm. The cold air blown out from the air duct 4 has the acting force of a vortex street after coming out from the air outlet 5, so that the cold air firstly has a parabolic motion track and then starts to move horizontally, and the drainage structure can collect the condensate water which moves horizontally by limiting the distance between the flow collecting groove 2 and the air outlet 5, thereby being convenient for collecting the condensate water.

Further, the height of the side wall of the flow collecting groove 2 close to the air outlet 5 is less than the height of the side wall of the flow collecting groove 2 far away from the air outlet 5, and the height of the side wall of the flow collecting groove 2 far away from the air outlet 5 is less than the height of the air outlet 5. Through being close to collection groove 2 highly being less than collection groove 2 of the lateral wall of air outlet 5 and keeping away from the high setting of the lateral wall of air outlet 5 for the effect of interception can be played to the lateral wall that collection groove 2 kept away from air outlet 5, avoids the comdenstion water to directly fly through collection groove 2 after blowing off from air outlet 5, makes collection groove 2 can't play the effect of collecting the comdenstion water. Meanwhile, the height of the side wall of the air outlet 5 is smaller than that of the air outlet 5 by keeping away the flow collecting groove 2, so that the side wall of the flow collecting groove 2 is prevented from being higher than the air outlet 5, the air outlet of the air outlet 5 is shielded by the flow collecting groove 2, and the air outlet 5 generates squealing noise when air is supplied.

Further, the air conditioner also comprises a condenser, and a drainage groove 10 is communicated between the drainage groove 2 and a water pan of the condenser. The condensed water collected in the collecting groove 2 is drained to a water receiving tray of the condenser through the arrangement of the draining groove 10, and the recycling of the condensed water can be realized.
