Description

Technical Field

[0001] The utility model belongs to the field of drainage accessories for parallel units, in particular to a drainage device for parallel units. Background Art

[0002] As we all know, the internal coil temperature of the parallel unit is lower than the dew point temperature of the air, causing the water vapor in the air to condense into dewdrops; and the parallel unit generates a lot of condensed water during operation, which often needs to be collected through a water collection and drainage tray and then discharged externally. The State Intellectual Property Office issued an authorization announcement on January 23, 2024, with the authorization announcement number CN220379945U: "A water collection and drainage tray for an air-conditioning unit". The patent discloses a water collection and drainage tray device for an air-conditioning unit. However, when the device is in use, it relies on the gravity of the condensed water itself to drive the piston to move downward, thereby driving the sliding frame to move back and forth to automatically scrub the dust on the bottom wall of the water collection tray. However, this method does not drain the water in the drainage barrel cleanly and there will be residue, which makes the sliding frame not completely reset, resulting in poor cleaning effect, and the guide rod is long, resulting in a larger overall volume. Therefore, we designed a drainage device for a parallel unit. Utility Model Content

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] A parallel unit drainage device, such as Figure 1 , 2As shown, it includes a water collecting tray 1, the top side of the water collecting tray 1 is open, and a water outlet 2 is opened on the bottom side. A box body 3 is fixedly installed on the bottom side of the water collecting tray 1, and the box body 3 is connected with the water outlet 2. A drain port 7 is opened on the bottom side of the box body 3, which is characterized in that: a rotating shaft 4 is rotatably installed in the box body 3, one end of the rotating shaft 4 is rotatably installed on the box body 3 through a bearing, and the other end of the rotating shaft 4 is rotatably installed in a reserved hole opened in the box body 3 through a bearing and extends out of the box body 3, and a double hopper 5 is fixedly installed on the rotating shaft 4, and the double hopper 5 is symmetrically arranged on the left and right. The two sides of the housing 3 are provided with baffle rods 6, and the two ends of the baffle rods 6 are fixedly mounted on the housing 3. A reciprocating screw 8 is rotatably mounted in the water collecting tray 1 through a bearing, and the other end of the reciprocating screw 8 is rotatably mounted in the reserved hole opened on the water collecting tray 1 through a bearing, and passes through the reserved hole. The outer peripheral thread of the reciprocating screw 8 is matched with a scraper 9, and the scraper 9 can only move back and forth on the reciprocating screw 8. The rotating shaft 4 is connected to the reciprocating screw 8 through a transmission mechanism, and the transmission mechanism can make the reciprocating screw 8 always rotate in one direction. The utility model has a simple structure and an ingenious design. The left and right swing of the double-connected hopper 5 can drive the reciprocating screw 8 to always rotate in one direction, thereby driving the scraper 9 to move back and forth, scraping and cleaning the dust on the bottom wall of the water collecting tray 1, and the cleaning effect is better, and the condensed water in the water collecting tray 1 is driven to move toward the middle water outlet 2 together to achieve the purpose of cleaning. The overall volume is small, which can meet market demand and is suitable for promotion. When the condensed water falls on one side of the double-connecting hopper 5, the weight of one side of the double-connecting hopper 5 increases with the accumulation of condensed water, so that one side of the double-connecting hopper 5 is slanted and sank, and the double-connecting hopper 5 will swing to one side until one side of the double-connecting hopper 5 hits the baffle 6 on the same side and stops swinging, and the condensed water in one side of the double-connecting hopper 5 pours into the box body 3. At the same time, the other side of the double-connecting hopper 5 is located below the water outlet 2, and the other side of the double-connecting hopper 5 continues to collect water. When the other side of the double-connecting hopper 5 collects water to a certain extent, the double-connecting hopper 5 will swing to the other side, and so on. At this time, the rotating shaft 4 can be driven to rotate, thereby driving the reciprocating screw rod 8 to rotate through the transmission mechanism, and then driving the scraper 9 to move back and forth, scraping and cleaning the dust on the bottom wall of the water collecting tray 1, and driving the condensed water in the water collecting tray 1 to move toward the middle water outlet 2 together, and finally discharged from the box body 3 through the drain port 7.

[0017] Specifically, as shown in the figure, the transmission mechanism of this embodiment includes a first gear 20, the rotating shaft 4 is rotatably connected with the first gear 20 through a one-way bearing 21, the rotating shaft 4, the one-way bearing 21 and the first gear 20 are coaxially arranged, the inner periphery of the one-way bearing 21 is fixedly connected with the outer periphery of the rotating shaft 4, the outer periphery of the one-way bearing 21 is fixedly connected with the inner periphery of the first gear 20, the coaxial second gear 22 is fixedly installed on the reciprocating screw 8, and the first gear 20 is transmission-connected with the second gear 22 through several transmission gears 23. When the double-connecting hopper 5 swings to the right, the rotating shaft 4 is driven to rotate, at which time the rotating shaft 4 can drive the first gear 20 to rotate, and the first gear 20 can drive the second gear 22 to rotate forwardly through the transmission gear 23; when the double-connecting hopper 5 swings to the left, due to the action of the one-way bearing 21, the rotating shaft 4 cannot drive the first gear 20 to rotate, that is, it cannot drive the second gear 22 to rotate in the opposite direction, so that the reciprocating screw 8 can only rotate in one direction, thereby driving the scraper 9 to move back and forth on the reciprocating screw 8.

[0018] Specifically, as shown in the figure, the transmission gear 23 of this embodiment is provided with two, and the inner circumference of the transmission gear 23 is fixedly installed with a rotating shaft, and the rotating shaft is rotatably installed on the box body 3 through a bearing, and the two transmission gears 23 are meshed and matched, and one transmission gear 23 is meshed and matched with the first gear 20, and the other is meshed and matched with the second gear 22. The rotation of the first gear 20 can drive the transmission gear 23 to rotate, thereby driving the second gear 22 to rotate.

[0019] Further, as shown in the figure, a rectangular frame 40 is fixedly installed on the top of the water collecting pan 1 in this embodiment, a fixing plate 41 is placed above the rectangular frame 40, a plurality of through slots 42 are opened on the fixing plate 41, and a water seepage cloth 43 is fixed on the top side of the fixing plate 41. When water drops from the upper parallel unit fall on the water seepage cloth 43, splashing can be prevented, and the noise of water drops directly falling on the water collecting pan 1 can be reduced, and the water drops can enter the water collecting pan 1 through the through slots 42, and the rectangular frame 40 can clamp the fixing plate 41, and it is convenient to remove the fixing plate 41.

[0020] Furthermore, as shown in the figure, the scraper 9 of this embodiment is provided with a threaded hole 50, the inner thread of the threaded hole 50 is matched with the installation of the reciprocating screw 8, and the scraper 9 is provided with two through holes 51, and the through holes 51 are respectively slidably fitted with a slide bar 52, the slide bar 52 is arranged parallel to the reciprocating screw 8, and the two ends of the slide bar 52 are respectively fixedly mounted on the water collecting tray 1, and the bottom side of the scraper 9 is in sliding contact with the inner wall of the water collecting tray 1. The rotation of the reciprocating screw 8 can drive the scraper 9 to move back and forth, so that the water in the water collecting tray 1 quickly falls from the water outlet 2 into the box 3, and the slide bar 52 plays a limiting role.

[0021] Furthermore, as shown in the figure, the drain port 7 of this embodiment is connected with a switch valve 60. By opening or closing the switch valve 60, the water in the box body 3 can be discharged in a centralized manner.
