Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air duct housing and an air conditioner. Background Art

[0002] At the air outlet of the air conditioner, it is usually necessary to set an air guide blade to adjust the air outlet direction, and the air guide blade is usually set on the fan beam. Since the air outlet has hot air / cold air passing through for a long time, condensation water is easy to form, especially on the fan beam. In the prior art, condensation water will drip freely from the fan beam, and part of the condensation water will drip into the air conditioner, affecting the safety of the air conditioner. Summary of the invention

[0003] The problem solved by the invention is how to solve the problem of condensed water dripping on the fan blade cross beam and improve the safety of the air conditioner.

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

[0005] In one aspect, the present invention provides an air duct housing, the air duct housing having an air outlet, a fan blade beam being arranged at the air outlet, the fan blade beam having an inner side surface and an outer side surface of the beam facing the inner side or the outer side of the air outlet respectively, and a water guide rib is arranged on the bottom surface of the fan blade beam, the two ends of the water guide rib respectively extend to the outer side surface of the beam and the side wall of the air duct housing, for guiding condensed water attached to the outer side surface of the beam to the side wall of the air duct housing.

[0006] The air duct housing provided by the present invention is provided with a water guide rib on the bottom surface of the fan blade cross beam, and one end of the water guide rib extends to the outer side of the cross beam of the fan blade cross beam, and the other end of the water guide rib extends to the side wall of the air duct housing. In the actual working process, due to the air outlet of the air outlet, condensed water will be formed on the fan blade cross beam and gathered to the outer side of the cross beam of the fan blade cross beam under the action of the air outlet. The condensed water gathered on the outer side of the cross beam of the fan blade cross beam can be drained to the side wall of the air duct housing through the water guide rib, and flows downward through the side wall of the air duct housing, and finally falls into the water receiving tray. Compared with the prior art, the air duct housing provided by the present invention can drain the condensed water gathered on the fan blade cross beam to the side wall of the air duct housing by setting the water guide rib, so as to prevent the condensed water from dripping directly from the fan blade cross beam to the inside of the air conditioner, thereby improving the safety of the air conditioner.

[0007] Furthermore, a height of one end of the water guide rib close to the outer side surface of the beam relative to the bottom surface is smaller than a height of one end of the water guide rib close to the side wall of the air duct housing relative to the bottom surface.

[0008] In the air duct shell provided by the present invention, the height of one end of the water diversion rib close to the side wall of the air duct shell is greater than the height of the other end close to the outer side surface of the cross beam, so that during the water diversion process, the acceleration of condensed water in the flow direction becomes greater and greater, thereby improving the drainage speed, avoiding the condensed water from staying on the water diversion rib for too long, and reducing the risk of dripping. At the same time, the end of the side wall close to the air duct shell is longer in the gravity direction, so that the transition with the air duct shell is smoother, and the accumulation of condensed water at the connection between the water diversion rib and the side wall of the air duct shell is avoided.

[0009] Furthermore, one end of the water guide rib close to the outer side surface of the beam has a drainage plane flush with the outer side surface of the beam, and the bottom side of the water guide rib is provided with a drainage slope extending to the drainage plane and the side wall of the air duct housing respectively.

[0010] In the air duct shell provided by the present invention, during the water diversion process, condensed water flows from the outer side of the beam to the diversion plane, and then quickly flows to the side wall of the air duct shell through the diversion slope. The setting of the diversion slope enables the condensed water to flow more smoothly to the side wall of the air duct shell, avoiding the phenomenon of accumulated flow and dripping, thereby ensuring the diversion effect.

[0011] Furthermore, windshield side walls are provided on both sides of the water diversion rib, the diversion slope is provided between the two windshield side walls and respectively connected to the two windshield side walls, and the angle between the windshield side wall and the bottom surface of the fan blade cross beam is between 80° and 100°.

[0012] The air duct housing provided by the present invention arranges the drainage ribs obliquely or vertically on the bottom surface, thereby ensuring the wind-blocking effect of the multiple water-guiding ribs, further preventing condensed water on the water-guiding ribs from being blown off, and ensuring the drainage effect.

[0013] Furthermore, the height of one end of the water guide rib close to the outer side surface of the beam relative to the bottom surface is 0.3-0.7 mm, and the height of one end of the water guide rib close to the side wall of the air duct shell relative to the bottom surface is 7 mm-9 mm.

[0014] Furthermore, the width of the water guide rib at one end close to the outer side surface of the beam in a direction perpendicular to the flow direction is smaller than the width of the water guide rib at one end close to the side wall of the air duct housing in a direction perpendicular to the flow direction.

[0015] In the air duct shell provided by the present invention, the width of the side wall of the water diversion rib close to the air duct shell is greater than the width close to the outer side of the beam, so that the width of the water diversion path of the water diversion rib gradually increases from the outer side of the beam to the side wall of the air duct shell, so that the condensed water tends to be dispersed during the water diversion process, thereby increasing the contact area between the condensed water and the water diversion rib, and can further prevent the condensed water from dripping during the water diversion process, thereby ensuring the water diversion effect.

[0016] Furthermore, the width of one end of the water guide rib close to the outer side surface of the beam in a direction perpendicular to the drainage direction is 0.6mm-1mm, and the width of one end of the water guide rib close to the side wall of the air duct shell in a direction perpendicular to the drainage direction is 1.8mm-2.2mm.

[0017] Furthermore, there are a plurality of water guide ribs, which are distributed in parallel and at intervals on the bottom surface of the fan blade cross beam, and each of the water guide ribs extends from the outer side surface of the cross beam to the side wall of the air duct shell.

[0018] The air duct shell provided by the present invention is provided with a plurality of water diversion ribs, and the plurality of water diversion ribs are arranged in parallel and at intervals to form a water diversion rib group. Adjacent water diversion ribs can play a role of wind blocking to prevent condensed water on the water diversion ribs from being blown off. In addition, the plurality of water diversion ribs have strong water diversion capacity and high water diversion efficiency, and can prevent condensed water on the fan blade beam from accumulating and causing dripping.

[0019] Furthermore, the plurality of water diversion ribs include a first rib, a second rib and a third rib which are sequentially arranged in parallel, the first rib is arranged close to the air outlet, and the third rib is arranged away from the air outlet.

[0020] Furthermore, a fourth rib is provided on the bottom surface of the fan blade beam, and the fourth rib is provided between the third rib and the second rib and respectively connects the outer side surface of the beam and the side wall of the air duct shell, and the height of the fourth rib relative to the bottom surface is less than the height of the second rib relative to the bottom surface.

[0021] In the air duct housing provided by the present invention, the height of the fourth rib is smaller than the height of the second rib, which can facilitate demolding of multiple water-guiding ribs during the manufacturing process.

[0022] Furthermore, a drainage hole is provided on the fan blade cross beam, and the first rib and the second rib span under the drainage hole to drain the condensed water collected in the drainage hole to the side wall of the air duct housing.

[0023] The air duct shell provided by the present invention can collect condensed water on the upper surface of the fan blade beam by opening a drainage hole, and drain it to the side wall of the air duct shell through the first rib and the second rib below, thereby ensuring that the condensed water on the fan blade beam can flow down from the side wall of the air duct shell.

[0024] Furthermore, the plurality of water guide ribs are arranged at one end of the fan blade cross beam close to the side wall of the air duct shell.

[0025] The air duct housing provided by the present invention prevents the multiple water guide ribs from affecting the air outlet through arranging the multiple water guide ribs at one end of the fan blade cross beam.

[0026] Furthermore, the bottom surface of the fan blade cross beam is also provided with a wind-shielding rib, the wind-shielding rib has a relative windward side and a leeward side, the water diversion rib is arranged on the windward side of the wind-shielding rib, and the wind-shielding rib extends to the side wall of the air duct shell.

[0027] The air duct shell provided by the present invention can further play a wind-blocking role by additionally arranging wind-blocking ribs, thereby reducing the risk of condensed water flowing on the water-guiding ribs being blown off by the wind blown out of the air outlet; at the same time, by arranging wind-blocking ribs on the windward side of multiple water-guiding ribs, it is possible to prevent condensed water on the water-guiding ribs from swirling with the scattered wind, and to reaggregate the water droplets that fall with the swirling scattered wind and guide them to the side walls of the air duct shell.

[0028] On the other hand, the present invention provides an air conditioner, including an air duct housing, the air duct housing including an air duct housing having an air outlet, a fan blade beam being arranged at the air outlet, the fan blade beam having an inner side surface and an outer side surface of the beam respectively facing the inner side or the outer side of the air outlet, and a water guide rib being arranged on the bottom surface of the fan blade beam, the two ends of the water guide rib respectively extending to the outer side surface of the beam and the side wall of the air duct housing, for guiding condensed water attached to the outer side surface of the beam to the side wall of the air duct housing.

[0029] The air conditioner provided by the present invention provides a water guide rib on the bottom side of the fan blade cross beam to guide the condensed water collected on the fan blade cross beam to the side wall of the air duct housing, thereby preventing the condensed water from dripping directly from the fan blade cross beam into the interior of the air conditioner, thereby improving the safety of the air conditioner.

DETAILED DESCRIPTION

[0039] As mentioned in the background technology, in the prior art, since condensation water is easily attached to the fan blade cross beam, the conventional means is to make the fan blade cross beam inclined toward the side wall of the air duct housing or to open a drainage hole extending to the side wall of the air duct housing, so that the condensation water can be drained to the side wall of the air duct housing. However, the inventor found through research that when the hot air / cold air continues to blow out of the air outlet, under the action of wind force, the condensation water will gather outward and eventually gather on the outer side of the cross beam of the fan blade cross beam, so the condensation water will generally drip from the outer side of the cross beam of the fan blade cross beam. The air duct housing provided by the present invention can smoothly drain the condensation water on the outer side of the cross beam of the fan blade cross beam to the side wall of the air duct housing, and prevent the condensation water from dripping from the outer side of the cross beam of the fan blade cross beam.

[0040] 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.

[0041] First embodiment

[0042] See also Figures 1 to 4 The present invention provides an air conditioning housing 100 installed on an air conditioning base 210, which can prevent condensed water on the beam from dripping into the interior of the air conditioner 200, thereby ensuring the safety of the air conditioner 200.

[0043] The air-conditioning shell 100 provided in the present embodiment has an air duct shell 110 with an air outlet, and a fan blade beam 130 is erected at the air outlet. The fan blade beam has an inner side surface and an outer side surface of the beam respectively exempting the inner side or outer side of the air outlet, and the outer side surface of the beam is farther away from the air outlet 190 than the inner side surface of the beam, and a water guide rib 150 is provided on the bottom surface of the fan blade beam 130, one end of the water guide rib 150 extends to the outer side surface of the beam, and the other end of the water guide rib 150 extends to the side wall of the air duct shell 110, which is used to guide condensed water on the outer side surface of the beam to the side wall of the air duct shell 110.

[0044] In this embodiment, the inner side of the fan blade cross beam 130 has a mounting side edge, and is fixed to the side wall of the air duct housing 110 through the mounting side edge. A water receiving tray is provided at the bottom of the air duct housing 110, and condensed water flows down through the side wall of the air duct housing 110 and finally flows into the water receiving tray. Specifically, the mounting side edge is arc-shaped, and the side wall of the air duct housing 110 is also a corresponding arc-shaped surface. Of course, the fan blade cross beam 130 here can also be directly fixed to the side wall of the air duct housing 110 through the end, and the connection structure between the fan blade cross beam 130 and the side wall of the air duct housing 110 can be adaptively improved according to different air duct housings 110.

[0045] In this embodiment, a water diversion rib 150 is provided on the bottom surface of the fan blade beam 130, and one end of the water diversion rib 150 extends to the outer side surface of the fan blade beam 130, and the other end of the water diversion rib 150 extends to the side wall of the air duct shell 110. In the actual working process, due to the air outlet of the air outlet 190, condensation water will be formed on the fan blade beam 130 and gathered to the outer side surface of the fan blade beam 130 under the action of the air outlet. The condensation water gathered on the outer side surface of the fan blade beam 130 can be drained to the side wall of the air duct shell 110 through the water diversion rib 150, and flow downward through the side wall of the air duct shell 110, and finally fall into the water receiving tray.

[0046] See also Figures 5 to 7 There are multiple water guide ribs 150, which are arranged in parallel and at intervals on the bottom surface of the fan blade cross beam 130, and each water guide rib 150 extends from the outer side of the cross beam to the side wall of the air duct housing 110. By providing multiple water guide ribs 150, and multiple water guide ribs 150 are arranged in parallel and at intervals, a group of water guide ribs 150 is formed, and adjacent water guide ribs 150 can play a role of blocking the wind, preventing the condensed water on the water guide ribs 150 from being blown off. In addition, the multiple water guide ribs 150 have strong water guide capacity and high water guide efficiency, and can prevent the condensed water on the fan blade cross beam 130 from accumulating and dripping.

[0047] In this embodiment, the plurality of water guide ribs 150 are arranged at one end of the fan blade cross beam 130 close to the side wall of the air duct housing 110. By arranging the plurality of water guide ribs 150 at one end of the fan blade cross beam 130, the plurality of water guide ribs 150 are prevented from affecting the air outlet.

[0048] In this embodiment, the fan blade beam 130 is horizontally placed outside the air outlet 190, and the angle between the setting direction of the multiple water diversion ribs 150 and the setting direction of the fan blade beam 130 is between 30° and 60°, so that the water diversion ribs 150 can directly divert water from the middle position of the fan blade beam 130 to the side wall of the air duct shell 110, thereby expanding the water diversion range.

[0049] In this embodiment, the plurality of water diversion ribs 150 are divided into different rib structures according to the different connection structures between the fan blade cross beam 130 and the side wall of the air outlet housing. Specifically, the plurality of water diversion ribs 150 include a first rib 151, a second rib 153 and a third rib 155 arranged in sequence, the first rib 151 is arranged close to the air outlet 190, the third rib 155 is arranged away from the air outlet, and the third rib 155 is the shortest in length, and the first rib 151 and the second rib 153 are the largest in size.

[0050] In this embodiment, the third rib 155 is arranged near the edge of the fan blade cross beam 130, and the arrangement of the first rib 151, the second rib 153, and the third rib 155 is limited by the specific structure of the fan blade cross beam 130. Specifically, a plurality of buckle structures for assembling the fan blade rotating shaft are sequentially arranged at intervals on the outer side of the cross beam of the fan blade cross beam 130, and the water guide rib 150 is connected to the side wall of the fan blade cross beam 130 between two adjacent buckle structures.

[0051] In this embodiment, the height of one end of each water guide rib 150 close to the outer side of the beam relative to the bottom surface is less than the height of one end close to the side wall of the air duct housing 110 relative to the bottom surface. The height of one end of each water guide rib 150 close to the side wall of the air duct housing 110 is greater than the height of one end close to the outer side of the beam, so that the acceleration of condensed water in the flow direction becomes larger and larger during the water guide process, the drainage speed is increased, and the condensed water is prevented from staying too much on the water guide rib 150, reducing the risk of dripping. At the same time, the end of the side wall close to the air duct housing 110 is longer in the gravity direction, so that the transition with the air duct housing 110 is smoother, and the condensed water is prevented from accumulating at the connection between the water guide rib 150 and the side wall of the air duct housing 110.

[0052] Each water guide rib 150 has a drainage plane 150a flush with the outer side of the beam at one end close to the outer side of the beam, and a drainage slope 150b extending to the drainage plane 150a and the side wall of the air duct housing 110 is provided at the bottom of each water guide rib 150. During the water diversion process, the condensed water flows from the outer side of the beam to the drainage plane 150a, and then quickly flows to the side wall of the air duct housing 110 through the drainage slope 150b. The setting of the drainage slope 150b allows the condensed water to flow more smoothly to the side wall of the air duct housing 110, avoiding the phenomenon of accumulated flow and dripping, and ensuring the drainage effect.

[0053] In this embodiment, both sides of each water diversion rib 150 are provided with windproof side walls 150c, the drainage slope 150b is arranged between the two windproof side walls 150c and connected to the two windproof side walls 150c respectively, and the angle between the windproof side wall 150c and the bottom surface of the fan blade cross beam 130 is between 80° and 100°. Preferably, the angle between the windproof side wall 150c on the windward side and the bottom surface of the fan blade cross beam 130 is 90 degrees, that is, the water diversion rib 150 is arranged vertically on the bottom surface. The diversion ribs are arranged obliquely or vertically on the bottom surface, which ensures the windproof effect of the multiple water diversion ribs 150, further avoids the condensed water on the water diversion ribs 150 from being blown off, and ensures the drainage effect.

[0054] In this embodiment, the height of one end of each water guide rib 150 close to the outer side of the beam relative to the bottom surface is 0.3-0.7mm, and the height of one end of each water guide rib 150 close to the side wall of the air duct housing 110 relative to the bottom surface is 7mm-9mm. Specifically, the height of one end of the first rib 151 and the second rib 153 close to the outer side of the beam relative to the bottom surface is 0.5mm, and the height of one end of the first rib 151 and the second rib 153 close to the side wall of the air duct housing 110 relative to the bottom surface is 8mm. The height of one end of the third rib 155 close to the outer side of the beam relative to the bottom surface is less than or equal to 0.5mm, and the height of one end close to the side wall of the air duct housing 110 relative to the bottom surface is less than or equal to 8mm, and the size of the third rib 155 is less than or equal to the size of the first rib 151.

[0055] The width of one end of each water guide rib 150 close to the outer side of the beam in the direction perpendicular to the drainage direction is smaller than the width of one end close to the side wall of the air duct housing 110 in the direction perpendicular to the drainage direction. The width of the water guide rib 150 close to the side wall of the air duct housing 110 is greater than the width close to the outer side of the beam, so that the width of the water guide path of the water guide rib 150 gradually increases from the outer side of the beam to the side wall of the air duct housing 110, so that the condensed water tends to disperse from enrichment during the water guide process, and the contact area between the condensed water and the water guide rib 150 is increased, which can further prevent the condensed water from dripping during the water guide process and ensure the water guide effect.

[0056] In this embodiment, the width of each water guide rib 150 at one end close to the outer side of the beam in the direction perpendicular to the drainage is 0.6mm-1mm, and the width of each water guide rib 150 at one end close to the side wall of the air duct housing 110 in the direction perpendicular to the drainage is 1.8mm-2.2mm. Specifically, the width of the first rib 151 and the second rib 153 at one end close to the outer side of the beam in the direction perpendicular to the drainage is 0.8mm, the width of the first rib 151 and the second rib 153 at one end close to the side wall of the air duct housing 110 in the direction perpendicular to the drainage is 2mm, and the width of the third rib 155 is less than or equal to the width of the first rib 151.

[0057] It should be noted that the drainage direction mentioned in this embodiment refers to the direction of the flow path of the condensed water on the water diversion rib 150. Since the water diversion has a drainage plane 150a and a drainage slope 150b, the condensed water flows vertically downward at the drainage plane 150a, and the condensed water flows obliquely downward at the drainage slope 150b. The flow direction of the condensed water forms a drainage vertical plane. The water diversion rib 150 is arranged on the bottom surface of the fan blade beam 130 along the drainage vertical plane. The width direction of the water diversion rib 150 refers to the direction perpendicular to the drainage vertical plane, that is, the horizontal width direction.

[0058] In this embodiment, a fourth rib 157 is further provided on the bottom surface of the fan blade beam 130. The fourth rib 157 is arranged between the third rib 155 and the second rib 153 and respectively connects the outer side surface of the beam and the side wall of the air duct shell 110. The height of the fourth rib 157 relative to the bottom surface is less than the height of the second rib relative to the bottom surface, which can facilitate the demolding of multiple water-guiding ribs 150 during the manufacturing process.

[0059] In this embodiment, the bottom surface of the fan blade cross beam 130 is further provided with a wind shield 170, which is arranged at an angle with the wind outlet direction and has a relative windward side and leeward side, and the plurality of water guide ribs 150 are all arranged on the leeward side of the wind shield 170, and the wind shield rib 170 extends to the side wall of the air duct housing 110. Specifically, the wind shield rib 170 is arranged on the windward side of the first rib 151. By additionally arranging the wind shield rib 170, it can further play a wind shielding role, reducing the risk of the wind blown out of the air outlet 190 blowing off the condensed water flowing on the water guide rib 150. At the same time, by arranging the wind shield rib 170 on the windward side of the plurality of water guide ribs 150, it can prevent the condensed water on the water guide rib 150 from swirling with the scattered wind, and can play a role in re-aggregating the water droplets that fall with the swirling scattered wind and guiding them to the side wall of the air duct housing 110.

[0060] Specifically, the size of the wind shield 170 is smaller than that of the water guide 150, and it is connected to the bottom surface of the fan blade cross beam 130 and the side wall of the air duct housing 110 respectively, so as to play a role of wind shielding. The wind shield 170 is arranged on the windward side of the water guide 150 closest to the air outlet 190, which can prevent the backflow phenomenon from occurring in the top corner cavity between the water guide 150, the fan blade cross beam 130 and the side wall of the air outlet housing, thereby affecting the normal flow of condensed water on the water guide 150, and prevent the scattered wind on the windward side of the water guide 150 from blowing away the condensed water and causing the condensed water to swirl. In addition, when the wind force is too strong, the wind shield 170 can also play a role in re-gathering the water droplets that are forced to swirl with the scattered wind on it, and flow to the side wall of the air duct housing 110.

[0061] In this embodiment, a drainage hole 131 is further provided on the fan blade cross beam 130, and the first rib 151 and the second rib 153 are arranged across the bottom of the drainage hole 131 to drain the condensed water collected in the drainage hole 131 to the side wall of the air duct housing 110. By providing the drainage hole 131, the condensed water on the upper surface of the fan blade cross beam 130 can be collected together and drained to the side wall of the air duct housing 110 through the first rib 151 and the second rib 153 below, ensuring that the condensed water on the fan blade cross beam 130 can flow down from the side wall of the air duct housing 110.

[0062] In summary, the air conditioner housing 100 provided in this embodiment, by providing a water guide rib 150 on the bottom side of the fan blade cross beam 130, the condensed water on the outer side of the fan blade cross beam 130 is guided to the side wall of the air duct housing 110, and flows downward through the side wall of the air duct housing 110, and finally falls into the water receiving tray, which can effectively prevent the condensed water on the fan blade cross beam 130 from directly dripping into the air conditioner 200, thereby improving the safety of the air conditioner 200. In addition, by providing a plurality of water guide ribs 150 and wind shielding ribs 170, the condensed water on the water guide rib 150 can be prevented from being blown away by the outlet wind, thereby ensuring the water guide effect and further preventing the condensed water from dripping.
