Description

Technical Field

[0001] This utility model relates to the field of evaporators, and in particular to an energy-saving and high-efficiency evaporator. Background Technology

[0002] Air conditioners and refrigerators are everyday household appliances. Air conditioners can change the indoor temperature, and refrigerators can keep food fresh by lowering the temperature. Because of these special abilities, they have entered thousands of households. However, the evaporator, as one of the most important components, absorbs the heat of the refrigerant through the evaporation process of the refrigerant to achieve the purpose of cooling. It can be understood as a heat exchanger. However, the evaporators on the market still have defects.

[0003] In modern dry evaporator products, scale will form on the water after long-term use during water circulation. Some of the scale will eventually accumulate on the filter screen at the outlet. The long-term accumulation of scale will clog the filter screen, which will slow down the water flow rate. In addition, heat will be carried away by the refrigerant in the heat transfer pipes. Some scale will adhere to the wall of the heating element, which will reduce the efficiency of heat transfer and affect the cooling effect of the evaporator. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an energy-efficient and high-efficiency evaporator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Preferably, a fixed shaft is fixedly installed between the inner walls of the cleaning box, a rotating plate is rotatably sleeved on the fixed shaft, and a torsion spring is fixedly connected between the rotating plate and the inner wall of the cleaning box.

[0009] Preferably, an outlet and an inlet are fixedly installed on the outer casing, the heat transfer pipe is connected to the outlet and inlet via a flexible hose, and a control device corresponding to the motor is fixedly installed on the outer casing.

[0018] Reference Figures 1-4An energy-efficient evaporator includes a shell 1, a mounting bracket 3 slidably mounted on the shell 1, a heat transfer pipe 2 fixedly mounted on the mounting bracket 3, refrigerant added from the inlet, the refrigerant absorbs heat from the water and vaporizes in the heat transfer pipe 2, and is discharged from the outlet and becomes refrigerant again. The refrigerant is existing technology, so the working principle will not be described in detail. A motor 5 is fixedly mounted on the shell 1, a lead screw sleeve 6 is fixedly connected to the output end of the motor 5, the lead screw sleeve 6 is mechanically matched with a reciprocating lead screw 8 through a lead screw slider, the reciprocating lead screw 8 passes through the bottom of the shell 1 and is fixedly connected to a cleaning box 12, a fixing block 7 is slidably sleeved on the reciprocating lead screw 8, the fixing block 7 is fixedly connected to the inner wall of the shell 1, a cleaning shaft 9 is rotatably mounted on the inner wall of the cleaning box 12, a cleaning scraper is fixedly mounted on the cleaning shaft 9, the cleaning shaft 9 passes through the cleaning box 12 and is fixedly connected to a gear 10, a double-sided rack 17 meshing with the gear 10 is fixedly mounted on the shell 1, and a vibration structure is mounted on the cleaning box 12.

[0019] When motor 5 is started, the lead screw sleeve 6 connected to the output end of motor 5 rotates. Under the action of the lead screw slider and the fixed block 7, the reciprocating lead screw 8 cannot rotate. Therefore, the reciprocating lead screw 8 moves up and down, and the cleaning box 12 connected to the reciprocating lead screw 8 moves up and down. The cleaning shaft 9 mounted on the cleaning box 12 moves up and down accordingly, and the gear 10 connected to the cleaning shaft 9 moves up and down. During the upward movement, when gear 10 moves to the position where it meshes with the double-sided rack 17, the movement of gear 10 will cause it to rotate counterclockwise (towards...). Figure 3 (For reference), the cleaning shaft 9 rotates counterclockwise, and the cleaning scraper on the cleaning shaft 9 rotates accordingly to scrape off the scale deposited on the filter screen 4;

[0020] The vibration structure includes a mounting plate 14, with a rotating shaft 15 rotatably mounted between the mounting plates 14. The rotating shaft 15 passes through the mounting plate 14 and is fixedly connected to a gear 16. The gear 16 meshes with a double-sided rack 17. A cam 18 is fixedly sleeved on the mounting plate 14. The cam 18 corresponds to the position of the mounting frame 3. When the cam 18 rotates, it can squeeze the mounting frame 3. A sliding groove is opened on the outer shell 1. A slider is slidably connected in the sliding groove. The slider is fixedly connected to the mounting frame 3. A spring is fixedly connected between the slider and the inner wall of the sliding groove. The spring amplifies the vibration.

[0021] During the up-and-down movement of the cleaning box 12, the mounting plate 14 connected to the cleaning box 12 moves up and down, the rotating shaft 15 moves accordingly, and the gear 16 fixedly connected to the rotating shaft 15 moves up and down. During the up-and-down reciprocating movement of the gear 16, when the gear 16 meshes with the double-sided rack 17, the gear 16 rotates, driving the rotating shaft 15 to rotate, driving the cam 18 on the rotating shaft 15 to rotate, squeezing the mounting bracket 3, the mounting bracket 3 slides, driving the sliding block to slide, the sliding block squeezes the spring, causing the spring to deform, when the cam 18 separates from the mounting bracket 3, the elastic force of the spring causes the mounting bracket 3 to return to its original position, the mounting bracket 3 vibrates when it moves back and forth continuously, driving the heat transfer pipe 2 to vibrate, shaking the scale attached to the heat transfer pipe 2 into the water, and then the water flow carries it to the filter screen 4 at the outlet.

[0022] A fixed shaft 13 is fixedly installed between the inner walls of the cleaning box 12. A rotating plate 11 is rotatably sleeved on the fixed shaft 13. A torsion spring is fixedly connected between the rotating plate 11 and the inner wall of the cleaning box 12. The torsion spring allows the rotating plate 11 to return to its original position after rotation, keeping the scale inside the cleaning box 12 and preventing water flow from opening the rotating plate 11 and allowing the scale to re-enter the outer shell 1. When the cleaning shaft 9 rotates and cleans the scale on the filter screen 4, the cleaning shaft 9 continues to rotate. When it rotates to the position of the rotating plate 11, the cleaning shaft 9 squeezes the rotating plate 11, causing the rotating plate 11 to rotate. The torsion spring deforms, and at this time, the cleaning scraper tilts downward, sending the cleaned scale into the interior of the cleaning box 12. When the cleaning shaft 9 separates from the rotating plate 11, the torsion spring returns to its original position, and the rotating plate 11 returns to its original position.

[0023] An outlet and an inlet are fixedly installed on the outer casing 1. The heat transfer pipe 2 is connected to the outlet and inlet via a flexible hose. The flexible hose ensures that the heat transfer pipe 2 is not affected by vibration. A control device corresponding to the motor 5 is fixedly installed on the outer casing 1. The control device is existing technology and can control the start and stop of the motor 5.

[0024] The rotating plate 11 is tilted, meaning that when the torsion spring is in its normal state, the rotating plate 11 is tilted and extends below the cleaning shaft 9. A baffle is fixedly installed on the cleaning box 12, and the position of the baffle corresponds to that of the rotating plate 11. The installation position of the rotating plate 11 is located on the outside of the baffle. The cleaning scraper will not contact the baffle when rotating. As the cleaning scraper moves, when the cleaning scraper rotates to the position of the rotating plate 11, the cleaning scraper squeezes the rotating plate 11, causing the rotating plate 11 to rotate. At this time, the cleaning scraper is tilted downwards, and the scale scraped off by the cleaning scraper slides into the cleaning box 12. After the cleaning scraper separates from the rotating plate 11, the torsion spring causes the rotating plate 11 to return to its original position. The rotating plate 11 and the baffle together seal the scale in the cleaning box 12. A filter hole is opened on the side wall of the cleaning box 12, which allows the interior of the cleaning box 12 to communicate with the outside. The surface of the cam 18 is covered with a protective layer, which protects the cam 18 from damage when it squeezes the mounting bracket 3.

[0025] In this invention, refrigerant is first added through the inlet, then the motor 5 is started. The lead screw sleeve 6 connected to the output end of the motor 5 rotates. Under the action of the lead screw slider and the fixed block 7, the reciprocating lead screw 8 cannot rotate. Therefore, the reciprocating lead screw 8 moves up and down, and the cleaning box 12 connected to the reciprocating lead screw 8 moves up and down. During the up and down movement of the cleaning box 12, the mounting plate 14 connected to the cleaning box 12 moves up and down, and the rotating shaft 15 moves accordingly. The gear 16 fixedly connected to the rotating shaft 15 moves up and down. During the up and down reciprocating movement of the gear 16, when the gear 16 meshes with the double-sided rack 17, the gear 16 rotates, driving the rotating shaft 15 to rotate, which in turn drives the cam 18 on the rotating shaft 15 to rotate, squeezing the mounting bracket 3. The mounting bracket 3 slides, causing the sliding block to slide. The sliding block squeezes the spring, causing the spring to deform. When the cam 18 separates from the mounting bracket 3, the spring force causes the mounting bracket 3 to return to its original position, continuously moving back and forth. When the mounting bracket 3 vibrates, it causes the heat transfer pipe 2 to vibrate, shaking off the scale adhering to the heat transfer pipe 2 into the water. The scale is then carried by the water flow to the filter screen 4 at the outlet. At the same time, the cleaning shaft 9 installed on the cleaning box 12 also moves up and down. The gear 10 connected to the cleaning shaft 9 moves up and down. During the upward movement of the gear 10, when the gear 10 moves to the position where it meshes with the double-sided rack 17, the movement of the gear 10 will cause it to rotate counterclockwise, driving the cleaning shaft 9 to rotate counterclockwise. The cleaning scraper on the cleaning shaft 9 will rotate accordingly, scraping off the scale deposited on the filter screen 4. After the cleaning shaft 9 has cleaned the scale on the filter screen 4, the cleaning shaft 9 continues to rotate. When it rotates to the position of the rotating plate 11, the cleaning shaft 9 squeezes the rotating plate 11, causing the rotating plate 11 to rotate. The torsion spring deforms, and at this time the cleaning scraper tilts downward, sending the cleaned scale into the interior of the cleaning box 12. When the cleaning shaft 9 separates from the rotating plate 11, the torsion spring returns to its original position, and the rotating plate 11 returns to its original position.
