[0041] Embodiment 1
[0042] In order to solve the problem in the prior art that the condensed water recovery device generates noise when collecting condensed water, thereby affecting the user experience, the utility model provides a condensed water recovery device for collecting condensed water.
[0043] like Figures 1 to 8 As shown, the condensate recovery device includes a housing 10 and a slow flow assembly, the housing 10 has a liquid inlet 110, the slow flow assembly includes a drainage boss 20 and a water retaining rib 30, the drainage boss 20 is arranged on the inner wall surface of the housing 10 and protrudes toward the inside of the housing 10, the drainage boss 20 has a guide surface 210 arranged on the outer edge of the liquid inlet 110, the water retaining rib 30 is arranged inside the housing 10, and at least a portion of the water retaining rib 30 is opposite to the liquid inlet 110 and is arranged at a distance.
[0044] Specifically, the condensate recovery device of the present application adopts a drainage boss 20 and a water retaining rib 30 to be set at the liquid inlet 110, so that when the water flow of the condensate entering the liquid inlet 110 is small, the condensate can flow under the guidance of the guide surface 210 of the drainage boss 20, avoiding the condensate from directly dripping to the bottom of the box 10 and causing a ticking sound; when the water flow of the condensate entering the liquid inlet 110 is large, the condensate will contact the water retaining rib 30 and flow toward the bottom of the box 10 under the guidance of the water retaining rib 30, avoiding the condensate from directly impacting the bottom of the box 10 and causing a large noise. The present application effectively solves the problem of noise generated by the box 10 in the prior art when collecting condensate through the coordinated use of the drainage boss 20 and the water retaining rib 30, thereby improving the comfort of users.
[0045] Furthermore, the liquid inlet 110 is disposed on an end of the side plate of the housing 10 close to the top cover, so that the condensed water flowing through the liquid inlet 110 flows to the bottom of the housing 10 under the action of gravity.
[0046] Furthermore, the guide surface 210 is arranged along the outer edge of the liquid inlet 110 , so that when the flow rate of the condensed water is low, the condensed water falls on the guide surface 210 of the drainage boss 20 , thereby achieving the movement of the condensed water along the guide surface 210 .
[0047] In this embodiment, the drainage boss 20 and the liquid inlet 110 are arranged on the same side plate of the box body 10, the bottom of the drainage boss 20 is connected to the bottom surface of the box body 10, and the top of the drainage boss 20 has a guide surface 210. The condensed water flows along the drainage boss 20 to the bottom of the box body 10 to avoid the noise of dripping condensed water.
[0048] like Figures 1 to 8As shown, the water retaining rib 30 is arranged on the bottom surface of the box body 10 and extends toward the top of the box body 10. The water retaining rib 30 includes a baffle 310 and a guide plate 320. The baffle 310 is spaced apart from the liquid inlet 110. The baffle 310 has a baffle surface arranged toward the liquid inlet 110. Along the opening direction of the liquid inlet 110, the projection of the liquid inlet 110 is located inside the area of the baffle surface. The guide plate 320 is arranged on one side of the baffle 310 facing the liquid inlet 110 and extends toward one side of the liquid inlet 110. The guide plate 320 cooperates with the baffle 310 to form a T-shaped structure.
[0049] Specifically, the baffle 310 is used to contact the condensed water flowing from the liquid inlet 110 to the inside of the box 10, so that the condensed water flows toward the bottom of the box 10 along the drainage surface formed by the baffle 310 and the drainage plate 320, avoiding the condensed water directly impacting the bottom of the box 10 and causing noise problems.
[0050] Furthermore, a liquid-passing gap is formed between the baffle plate 310 and the liquid inlet 110 , and the guide plate 320 and the guide boss 20 are both arranged inside the liquid-passing gap, thereby providing a flow path for the flow of condensed water.
[0051] Among them, one end of the guide plate 320 is connected to the baffle 310, and the other end of the guide plate 320 is abutted against the guide boss 20, so that the guide plate 320 and the guide boss 20 can both achieve the drainage effect, and drainage can be performed regardless of the flow rate of condensed water to avoid noise.
[0052] Furthermore, the height of the guide plate 320 is smaller than the distance between the liquid inlet 110 and the bottom surface of the box body 10, so as to avoid the problem that the guide plate 320 blocks the flow of condensed water when the water flow of the condensed water is large.
[0053] In this embodiment, the baffle 310 contacts the condensed water that needs to flow from the liquid inlet 110 to the housing 10, and the drain plate 320 needs to avoid the condensed water at the liquid inlet 110, so the height of the baffle 310 is greater than the height of the drain plate 320, and the height difference between the baffle 310 and the drain plate 320 is H, 14mm≤H≤15mm, preferably 15mm. The diameter of the liquid inlet 110 is D, 6mm≤D≤7mm, preferably 7mm. Along the height direction of the housing 10, the minimum distance between the liquid inlet 110 and the top of the baffle 310 is h, 6mm≤h≤7mm, preferably 7mm.
[0054] It should be noted that when the sizes of the baffle 310 , the guide plate 320 and the liquid inlet 110 meet the above ranges, the noise reduction effect is the best.
[0055] Furthermore, the distance S between the baffle 310 and the wall surface where the liquid inlet 110 is located is 14 mm ≤ S ≤ 15 mm, preferably 15 mm. When the distance S between the baffle 310 and the wall surface where the liquid inlet 110 is located satisfies 14 mm ≤ S ≤ 15 mm, it is conducive to achieving that the condensed water can contact the baffle 310 and flow along the drainage surface formed by the baffle 310 and the drainage plate 320.
[0056] Furthermore, along the direction perpendicular to the opening direction of the liquid inlet 110, the length of the baffle 310 is T, 14 mm ≤ T ≤ 15 mm, preferably 15 mm. When the width of the baffle 310 satisfies 14 mm ≤ T ≤ 15 mm, the liquid flowing from the liquid inlet 110 to the inside of the box 10 can all contact with the baffle 310, thereby achieving a drainage effect.
[0057] In this embodiment, the water retaining rib 30 also includes a support plate 330, which is arranged on the side of the baffle 310 away from the guide plate 320, wherein the support plate 330 is used to support the baffle 310 to improve the installation stability of the baffle 310 and avoid the baffle 310 from being easily deformed under the impact of condensed water.
[0058] Among them, the support plate 330 extends in the direction away from the guide plate 320. Along the height direction of the box body 10, the projections of the baffle 310, the guide plate 320 and the support plate 330 are in a cross structure. In order to improve the stability of the support of the baffle 310, the support plate 330 is located in the middle area of the baffle 310 along the second direction. At the same time, in order to improve the drainage effect, the guide plate 320 is also arranged in the middle area of the baffle 310 along the second direction.
[0059] It should be noted that the first direction is the X direction shown in the figure, and the second direction is the Y direction not shown in the figure.
[0060] Embodiment 2
[0061] The utility model provides a heat exchange device, such as Figures 1 to 11 As shown, the heat exchange equipment includes the condensate recovery device, the evaporator and the drainage box 50 in Example 1. The housing 10 of the condensate recovery device has a liquid outlet 120. The drainage box 50 is arranged on the top of the evaporator. The drainage box 50 has a water separation chamber 501 and a water inlet and a water outlet connected to the water separation chamber 501. The water inlet is connected to the liquid outlet 120, and the water outlet is used to supply liquid to the top of the evaporator.
[0062] Specifically, the water diversion chamber 501 of the drainage box 50 is used to divert the liquid so as to achieve uniform flow of the liquid inside the drainage box 50 to the condenser 40 .
[0063] Furthermore, the drainage box 50 includes a box body 520 and a cover body 510, wherein the cover body 510 has a water inlet, and the cover body 510 and the box body 520 are connected to form a water diversion chamber 501, and a water outlet is provided on the plate section of the box body 520 opposite to the cover body 510. The box body 520 and the cover body 510 are sealed to form a sealed water diversion chamber 501 to prevent the occurrence of condensed water seepage.
[0064] Furthermore, the plate section of the box body 520 opposite to the cover body 510 also has an annular convex rib structure 60, which is arranged along the periphery of the water outlet, so that an annular water-dividing cavity 501 is formed between the convex rib structure 60 and the inner wall surface of the box body 520. The annular water-dividing cavity 501 is arranged around the periphery of the water outlet, which is conducive to uniformly injecting condensed water into the water outlet.
[0065] Furthermore, the convex rib structure 60 includes four rib plate segments connected end to end in sequence, and a group of relative rib plate segments extending along the length direction of the drainage box 50 are provided with guide notches 610. By setting the guide notches 610 on the convex rib structure 60, the condensed water can flow toward the water outlet at the position of the guide notches 610.
[0066] In this embodiment, since the height of the guide notch 610 is smaller than the height of the rib structure 60 , when the condensed water inside the water diversion cavity 501 reaches a certain height, the condensed water will overflow from the guide notch 610 to the water outlet to achieve water discharge.
[0067] like Figures 1 to 11 As shown, a plurality of guide notches 610 are provided on each rib plate segment, and the plurality of guide notches 610 are arranged at intervals along the length direction of the drainage box 50 .
[0068] Preferably, the guide notches 610 on the two rib structures 60 are staggered to improve the uniformity of the flow of condensed water toward the water outlet.
[0069] In this embodiment, the distance between the guide notch 610 and the plate section opposite to the cover body 510 is L, 3mm≤L≤5mm, preferably 5mm, that is, when the depth of the condensed water inside the water diversion chamber 501 exceeds 5mm, the condensed water will overflow from the guide notch 610 to the water outlet. Along the length direction of the drainage box 50, the length of the guide notch 610 is K, 8mm≤L≤10mm, preferably 10mm. When the length of the guide notch 610 satisfies 8mm≤L≤10mm, it is beneficial to improve the circulation efficiency of the condensed water. The distance between the plate section opposite to the box body 520 and the cover body 510 and the cover body 510 is W, 8mm≤L≤10mm, preferably 8mm, so as to achieve that the height of the box body 520 is not less than the height of the rib structure 60.
[0070] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:
[0071] The condensate recovery device of the present application adopts a drainage boss 20 and a water retaining rib 30 to be set at the liquid inlet 110, so that when the water flow of the condensate entering the liquid inlet 110 is small, the condensate can flow under the guidance of the guide surface 210 of the drainage boss 20, avoiding the condensate from directly dripping to the bottom of the box 10 and causing a ticking sound; when the water flow of the condensate entering the liquid inlet 110 is large, the condensate will contact the water retaining rib 30 and flow toward the bottom of the box 10 under the guidance of the water retaining rib 30, avoiding the condensate from directly impacting the bottom of the box 10 and causing a large noise. The present application effectively solves the problem of noise generated by the box 10 in the prior art when collecting condensate through the coordinated use of the drainage boss 20 and the water retaining rib 30, thereby improving the comfort of users.
