[0001] The present invention relates to the technical field of air conditioning, and in particular to a water-discharging and air-sweeping blade and an air conditioner. Background Art

[0002] In order to increase the air outlet area, the current air conditioner cabinet has a fake air outlet position. When the blades here are hit to the rightmost, a large amount of condensation water will be generated and slide down, gathering and dripping at the beak of the air duct. Under the action of cold wind, the air conditioner is blown out, affecting the user experience. Summary of the invention

[0003] The problem solved by the invention is how to prevent condensed water on the fan blades from dripping.

[0004] To solve the above problems, the present invention adopts the following technical solutions.

[0005] A water-draining wind-sweeping blade comprises a blade body and a mounting structure. The mounting structure is arranged on the blade body and is used to be connected to a fan blade crossbeam. The blade body is also provided with a water-guiding rib, which is located above the mounting structure and is obliquely arranged on the surface of the blade body to drain condensed water on the blade body to an adjacent fan blade crossbeam below.

[0006] The drainage and wind-sweeping blade provided by the present invention has a water-guiding rib on the blade body, and the water-guiding rib is arranged above the mounting structure. In actual operation, the condensed water on the blade body can be drained to the fan blade cross beam through the water-guiding rib, and the water is drained through the fan blade cross beam, so as to prevent the condensed water on the blade body from gathering at the mounting structure and dripping from the mounting structure, thereby preventing the condensed water on the blade body from being blown out of the air conditioner under the action of cold wind. Compared with the prior art, the drainage and wind-sweeping blade provided by the present invention can drain the condensed water on the blade body to the fan blade cross beam through the water-guiding rib, so as to prevent the condensed water from dripping directly on the mounting structure of the blade body, thereby preventing the air conditioner from being blown out under the action of cold wind, and improving the experience of the air conditioner.

[0007] Furthermore, the blade body has an inner side edge and an outer side edge opposite to each other, the mounting structure is arranged close to the inner side edge, and the water guide rib is protruded from at least one side surface of the blade body and extends from the outer side edge to the inner side edge.

[0008] The drainage and wind-sweeping blade provided by the present invention has a water-guiding rib protruding on the blade body and extending from the outer edge to the inner edge, so that the water-guiding rib can block and drain condensed water on the entire blade body, preventing condensed water from flowing to the installation structure below the water-guiding rib, thereby ensuring the effect of water blocking and drainage.

[0009] Furthermore, the water guide rib is obliquely arranged on the surface of the blade body, and the height of one end of the water guide rib close to the outer side relative to the adjacent mounting structure below is greater than the height of one end of the water guide rib close to the inner side relative to the adjacent mounting structure below.

[0010] The drainage and wind sweeping blade provided by the present invention has the water guide ribs inclinedly arranged, and the outer side height is greater than the inner side height, so that the water guide ribs drain from the outside to the inside, which facilitates the drainage of condensed water to the inner fan blade beam and prevents the condensed water from dripping directly from the outside.

[0011] Furthermore, the angle between the water guiding rib and the inner side edge is 40°-80°.

[0012] The drainage and wind sweeping blade provided by the present invention sets the angle between the water guide rib and the inner side edge so that the inclination angle of the water guide rib is appropriate, ensuring that condensed water is drained to the fan blade beam at an appropriate speed and avoiding the accumulation of condensed water on the water guide rib.

[0013] Furthermore, the water guiding rib comprises a plurality of water retaining sections, the plurality of water retaining sections are connected in sequence, and the slopes of two adjacent water retaining sections relative to the inner side edge are different.

[0014] The drainage and wind sweeping blade provided by the present invention divides the water guide rib into a plurality of water retaining sections, and the inclinations of two adjacent water retaining sections are different, so that different water retaining sections can adapt to different surface structures of the blade body and can collect condensed water on the blade body to the maximum extent.

[0015] Furthermore, the slopes of the multiple water retaining sections distributed in sequence along the inner side toward the outer side of the water guiding rib gradually increase or decrease relative to the inner side.

[0016] The drainage and wind sweeping blade provided by the present invention has multiple water retaining sections with increasing or decreasing slopes, so that the drainage speed of the water retaining section increases, the drainage is accelerated, and the accumulation of condensed water on the water retaining section is avoided. At the same time, the water retaining sections with increasing or decreasing slopes can make the transition of condensed water on adjacent water retaining sections smoother, thereby improving the drainage effect.

[0017] Furthermore, the plurality of water retaining sections include a starting section, a middle section and an end section connected in sequence, the starting section extends to the inner side, the end section extends to the outer side, and the slopes of the starting section, the middle section and the end section are all different.

[0018] The drainage and wind sweeping blade provided by the present invention divides the water retaining section into a starting section, a middle section and an end section with different inclinations, so that each section can adapt to different surface structures of the blade body, thereby improving the drainage effect.

[0019] Furthermore, there are multiple water-guiding ribs, each of which includes a starting section and an end section connected in sequence, one end of each starting section is connected to the inner edge, one end of each end section is connected to the outer edge, and the slopes of two adjacent starting sections are different, while the slopes of two adjacent end sections are the same, and the ends of multiple starting sections close to the inner edge are connected to each other.

When one of the water-guiding ribs overflows, the water-guiding ribs below can play a bearing role, and at the same time gather together in one place, which can conveniently gather the condensed water and finally drain it to the fan blade beam.

[0021] Furthermore, the water guide rib has an upper surface and a lower surface relative to each other, the upper surface is farther away from the mounting structure than the lower surface, and the upper surface is inclined on the surface of the blade body and forms a drainage groove with the surface of the blade body for draining condensed water.

[0022] The drainage and wind sweeping blade provided by the present invention has an upper surface of a water guide rib arranged obliquely and forms a drainage groove with the surface of the blade body, so that condensed water can be collected in the drainage groove for drainage, thereby improving the drainage effect.

[0023] Furthermore, the water-guiding rib also has a relative inner surface and an outer surface, the inner surface is arranged on the surface of the blade body, the outer surface is away from the blade body relative to the inner surface, and an arc-shaped transition surface is arranged between the outer surface and the lower surface to ensure a smooth transition between the outer surface and the lower surface.

[0024] The drainage and wind sweeping blade provided by the present invention has an arc-shaped transition surface between the outer surface and the lower surface of the water guide rib, so that the outer surface and the lower surface have a smooth transition, the airflow direction near the water guide rib is optimized, and the water guide rib is prevented from affecting the wind outlet effect.

DETAILED DESCRIPTION

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0043] First embodiment

[0044] See also Figure 1 and Figure 2 The present embodiment provides a drainage and sweeping blade 100, which can drain the generated condensed water to the blade beam 300, avoiding dripping from the mounting structure 130 of the drainage and sweeping blade 100 and being blown out of the air conditioner 10, thereby improving the experience of the air conditioner 10.

[0045] The drainage and wind-sweeping blade 100 provided in this embodiment includes a blade body 110 and a mounting structure 130. The mounting structure 130 is arranged on the blade body 110 and is used to be connected to the fan blade cross beam 300. The blade body 110 is also provided with a water guide rib 150. The water guide rib 150 is located above the mounting structure 130 and is used to drain the condensed water on the blade body 110 to the adjacent fan blade cross beam 300 below.

[0046] In this embodiment, a plurality of drainage and wind sweeping blades 100 are mounted on the fan blade cross beam 300, and a plurality of mounting structures 130 are arranged on each drainage and wind sweeping blade 100 in the vertical direction, and a water guide rib 150 is arranged above the mounting structure 130. Specifically, the mounting structure 130 is arranged at the wind duct beak structure of the fan blade cross beam 300, and can rotate relative to the fan blade cross beam 300, and its connection structure is consistent with the conventional fan blade cross beam 300. Of course, in other preferred embodiments, a water guide rib 150 can be arranged above one or two mounting structures 130 on each blade body 110, and the number of the water guide rib 150 is not specifically limited here.

[0047] It should be noted that the water guide rib 150 in this embodiment is integrally arranged on the blade body 110, and the outflow end of the water guide rib 150 is located above the surface of the fan blade beam 300. The condensed water on the fan blade body can be directly dripped onto the fan blade beam 300 after being drained by the water guide rib 150, thereby preventing the condensed water from flowing to the mounting structure 130 and dripping directly downward through the mounting structure 130 and the air duct hawkbill structure.

[0048] It should also be noted that the directional words such as above and below mentioned in this embodiment refer to the relative position relationship in the working state after assembly is completed, wherein the water guide rib 150 is located above the mounting structure 130, which means that the water guide rib 150 is located above the mounting structure 130 in the vertical direction after assembly is completed.

[0049] The drainage and wind sweeping blade 100 provided in this embodiment is provided with a water guide rib 150 on the blade body 110, and the water guide rib 150 is provided above the mounting structure 130. In actual operation, the condensed water on the blade body 110 can be drained to the fan blade cross beam 300 through the water guide rib 150. At the same time, a water collecting trough 310 is provided on the fan blade cross beam 300, and the water collecting trough 310 is connected to the inner wall of the air duct housing. The condensed water gathers in the water collecting trough 310, and is drained through the water collecting trough 310 on the fan blade cross beam 300, so as to prevent the condensed water on the blade body 110 from gathering at the mounting structure 130 and dripping from the mounting structure 130, thereby preventing the condensed water on the blade body 110 from being blown out of the air conditioner under the action of cold wind.

[0050] In this embodiment, the mounting structure 130 includes a mounting shaft. A mounting groove is provided on the blade body 110. The mounting shaft is disposed in the mounting groove and rotatably assembled on the fan blade cross beam 300. The blade body 110 is rotated by the mounting shaft.

[0051] See also Figure 3 and Figure 4 The blade body 110 has an inner side edge 111 and an outer side edge 113 relative to each other, the mounting structure 130 is arranged near the inner side edge 111, and the water guide rib 150 is convexly arranged on at least one side surface of the blade body 110, and extends from the outer side edge 113 to the inner side edge 111. Specifically, the inner side edge 111 and the outer side edge 113 are arranged in the vertical direction, the inner side edge 111 is the side edge of the blade body 110 close to the fan blade cross beam 300, and the outer side edge 113 is the side edge close to the external space, the mounting groove is provided on the inner side edge 111, and the mounting shaft is arranged near the inner side edge 111. At the same time, the water guide rib 150 is convexly arranged on the blade body 110, and extends from the outer side edge 113 to the inner side edge 111, so that the water guide rib 150 can block and drain the condensed water on the entire blade body 110, and prevent the condensed water from flowing to the mounting structure 130 below the water guide rib 150, thereby ensuring the effect of water blocking and drainage.

[0052] It is worth noting that in this embodiment, both sides of the blade body 110 are provided with water guide ribs 150, and this embodiment is described by taking one side as an example. In other preferred embodiments of the present invention, water guide ribs 150 may be provided only on one side of the blade body 110, and the water guide ribs 150 above two adjacent mounting structures 130 in the vertical direction may be provided on opposite surfaces, so that the water guide ribs 150 above multiple mounting structures 130 on the same blade body 110 can be arranged in an alternating manner, which can also achieve the function of guiding water on both sides.

[0053] In this embodiment, the water guide 150 is arranged obliquely on the surface of the blade body 110, and the height of one end of the water guide 150 close to the outer side 113 relative to the lower adjacent mounting structure 130 is greater than the height of one end of the water guide 150 close to the inner side 111 relative to the lower adjacent mounting structure 130. The water guide 150 is arranged obliquely, and the outer side height is greater than the inner side height, so that the water guide 150 drains from the outside to the inside, which facilitates draining condensed water to the inner fan blade beam 300, and prevents condensed water from dripping directly from the outside.

[0054] It should be noted that in this embodiment, the overall structure of the water-guiding rib 150 is a straight rib, and its surface curve structure is the same as that of the blade, so that the water-guiding rib 150 can be closely arranged on the surface of the blade body 110 .

[0055] In this embodiment, the angle between the water guide rib 150 and the inner side edge 111 is 40°-80°. Specifically, the angle between the water guide rib 150 and the inner side edge 111 is 60°, that is, the angle between the water guide rib 150 and the horizontal direction is 30°, which ensures the water diversion effect while preventing the water guide rib 150 from being too long in the vertical direction, thereby increasing the manufacturing difficulty. The angle between the water guide rib 150 and the inner side edge 111 is set so that the inclination angle of the water guide rib 150 is appropriate, ensuring that the condensed water is diverted to the fan blade cross beam 300 at an appropriate speed, and preventing the condensed water from gathering on the water guide rib 150.

[0056] To sum up, the drainage and wind-sweeping blade 100 provided in this embodiment can drain the condensed water on the blade body 110 to the fan blade beam 300 and drain the water through the fan blade beam 300 by setting a water guide rib 150 above the mounting structure 130, thereby preventing the condensed water from gathering at the mounting structure 130, and preventing the condensed water from dripping through the mounting structure 130 and the air duct beak structure and being blown out of the air outlet, thereby improving the experience of the air conditioner 10.

[0057] Second embodiment

[0058] See also Figure 5This embodiment provides a drainage and wind sweeping blade 100, whose basic structure, principle and technical effects are the same as those of the first embodiment.

[0059] The drainage and wind-sweeping blade 100 provided in this embodiment includes a blade body 110 and a mounting structure 130. The mounting structure 130 is arranged on the blade body 110 and is used to be connected to the fan blade cross beam 300. The blade body 110 is also provided with a water guide rib 150. The water guide rib 150 is located above the mounting structure 130 and is used to drain the condensed water on the blade body 110 to the fan blade cross beam 300.

[0060] In this embodiment, the water guide 150 includes a plurality of water retaining sections 151, which are connected in sequence, and the slopes of two adjacent water retaining sections 151 are different. The water guide 150 is divided into a plurality of water retaining sections 151, and the slopes of two adjacent water retaining sections 151 are different, so that different water retaining sections 151 can adapt to different surface structures of the blade body 110, and can collect condensed water on the blade body 110 to the maximum extent.

[0061] It should be noted that the slope mentioned in this embodiment refers to the slope of the water retaining section 151 relative to the inner side 111, that is, the slope of the water retaining section 151 relative to the vertical direction.

[0062] In this embodiment, the slopes of the multiple water retaining sections 151 gradually increase or decrease from the inner side edge 111 to the outer side edge 113. Specifically, the slopes of the multiple water retaining sections 151 gradually decrease from the inner side edge 111 to the outer side edge 113, so that the water guide ribs 150 formed by the multiple water retaining sections 151 are approximately in a curved structure, so that the drainage speed of the water retaining sections 151 increases gradually, the drainage is accelerated, and the condensed water is prevented from gathering on the water retaining sections 151. At the same time, the water retaining sections 151 with increasing slopes can make the transition of the condensed water on the adjacent water retaining sections 151 smoother, thereby improving the drainage effect.

[0063] In summary, the drainage and wind sweeping blade 100 provided in this embodiment can drain the condensed water on the blade body 110 to the blade cross beam 300 , and has a good drainage effect, thereby preventing the condensed water from gathering on the water guide rib 150 .

[0066] The drainage and wind sweeping blade 100 provided in this embodiment includes a blade body 110 and a mounting structure 130.

The water guide rib 150 is located above the mounting structure 130 and is used to guide the condensed water on the blade body 110 to the fan blade cross beam 300. The water guide rib 150 includes a plurality of water retaining sections 151, and the plurality of water retaining sections 151 are connected in sequence, and the inclinations of two adjacent water retaining sections 151 are different.

[0067] In this embodiment, the plurality of water retaining sections 151 include a starting section 153, a middle section 155 and a terminal section 157 connected in sequence, the starting section 153 extends to the inner side edge 111, the terminal section 157 extends to the outer side edge 113, and the starting section 153, the middle section 155 and the terminal section 157 have different slopes. The water retaining section 151 is divided into the starting section 153, the middle section 155 and the terminal section 157 with different slopes, so that each section can adapt to different surface structures of the blade body 110, thereby improving the drainage effect.

[0068] Specifically, the middle parts of the two side surfaces of the blade body 110 are in a convex state, and the middle part has a preliminary function of gathering condensed water. The middle section 155 is located in the middle of the blade body 110, so that the middle section 155 can receive most of the condensed water. Since the amount of condensed water gathered in the middle and edge of the blade body 110 is different, the flow rate and gathering speed of the condensed water are different. The condensed water can be better received through the starting section 153, the middle section 155 and the end section 157 with different slopes.

[0084] In this embodiment, a water collecting trough 310 is also provided on the fan blade cross beam 300, and the water collecting trough 310 corresponds to the water outlet side of the water guide rib 150, and the water guide rib 150 is also used to drain the condensed water on the blade body 110 to the water collecting trough 310. Specifically, the water collecting trough 310 is connected to the inner wall of the air conditioning housing 200, so that the condensed water in the water collecting trough 310 can be left along the inner wall of the air conditioning body to prevent water droplets from dripping and blowing out. By providing the water collecting trough 310 on the fan blade cross beam 300, the condensed water on the blade body 110 is collected by the water collecting trough 310, which improves the water collection effect, and prevents the condensed water from gathering on the fan blade cross beam 300 and dripping into the inside of the air conditioner 10, affecting the safety of the air conditioner 10.

[0085] In this embodiment, a plurality of drainage and wind sweeping blades 100 are mounted on the fan blade cross beam 300 , and a plurality of mounting structures 130 are arranged on each drainage and wind sweeping blade 100 in the vertical direction, and a water guide rib 150 is arranged above the uppermost mounting structure 130 .

[0086] It should be noted that in this embodiment, the water guide rib 150 is arranged above the uppermost mounting structure 130, and multiple blade bodies 110 are vertically arranged at the air outlet of the air-conditioning housing 200. The uppermost blade body 110 is above the air outlet, which is a false air outlet position. Therefore, condensation is most likely to occur at the uppermost blade body 110. By setting the water guide rib 150 above the uppermost mounting structure 130, the condensed water generated on the blade body 110 can be drained to the water collecting trough 310 on the fan blade beam 300 to prevent water droplets from dripping and being blown out.
