[0002] Evaporation is the physical process of converting liquid into gas. Generally speaking, an evaporator is an object that converts liquid into gas. There are a large number of evaporators in industry, among which the evaporator used in the refrigeration system is one of them. The evaporator is a very important component in the four major components of refrigeration. The low-temperature condensed liquid passes through the evaporator and exchanges heat with the air outside, vaporizes and absorbs heat, achieving the effect of refrigeration. The evaporator is an indispensable component in the refrigeration system. After the liquid refrigerant absorbs the heat of the cooled object in the evaporator, it vaporizes into low-temperature and low-pressure gas. In the home, the evaporator is mainly used in air conditioning and refrigerator refrigeration. The existing evaporator is prone to frost on the surface after long-term operation. If frost is not removed in time, it will affect the refrigeration effect of the evaporator and increase energy consumption. Therefore, we propose an energy-saving evaporator. SUMMARY

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figs. 1-3 An energy-saving evaporator includes a housing 1, a freezing chamber 2 at the bottom of the housing 1, an evaporator 3 inside the freezing chamber 2, an mounting plate 5 fixedly installed inside the freezing chamber 2 below the evaporator 3, three fan blades 16 evenly spaced above the evaporator 3, a drive structure at the top of the inside of the freezing chamber 2, and a guide structure between the fan blades 16 and the drive structure.

[0021] Furthermore, the drive structure includes a fixed plate 6, a motor 7, a rotating rod 8, a limiting cylinder 9, and a support frame 10. The top of the interior of the freezing chamber 2 is fixedly installed on the fixed plate 6. The motor 7 is provided on one side of the fixed plate 6, and the rotating rod 8 is fixedly installed at the output end of the motor 7. The fan blade 16 is installed at the bottom end of the rotating rod 8, and the limiting cylinder 9 is sleeved on the rotating rod 8. The support frame 10 is fixedly installed on the side of the limiting cylinder 9 adjacent to the fixed plate 6, and the support frame 10 has a T-shaped structure. The support frame 10 is rotatably connected to the fixed plate 6. When too much frost is generated on the surface of the evaporator tube on the evaporator 3, the user starts the motor 7. The output end of the motor 7 drives the rotating rod 8 to rotate. The rotation of the rotating rod 8 generates wind, which melts the frost on the evaporator 3.

[0022] Furthermore, the guiding structure includes a worm 11, a worm wheel 12, a first connecting rod 13, a second connecting rod 14, and a fixed rod 15. The worm 11 is fixedly installed on the rotating rod 8 between the limiting cylinder 9 and the fan blade 16. The worm wheel 12 is rotatably installed at the bottom end of the support frame 10, and the worm wheel 12 meshes with the worm 11. The first connecting rod 13 is rotatably installed on the worm wheel 12, and the free end of the first connecting rod 13 is rotatably connected to the second connecting rod 14. The free end of the second connecting rod 14 is rotatably connected to the fixed rod 15, and the other side of the fixed rod 15 is fixedly connected to the fixed plate 6. The rotating rod 8 rotates, causing the worm 11 to rotate together. The worm 11 causes the meshing worm wheel 12 to start rotating. The limiting cylinder 9 and the support frame 10 support the worm wheel 12. The rotation of the worm wheel 12 causes the first connecting rod 13 to rotate, and the free end of the first connecting rod 13 drives the second connecting rod 14. Thus, the fan blade 16 swings back and forth while rotating.

[0023] Furthermore, the interior of the freezing chamber 2 is symmetrically equipped with limit frames 4, and the cross-section of the limit frames 4 is U-shaped. The evaporator 3 is slidably connected between the two limit frames 4.

[0024] Furthermore, multiple water tanks 18 are evenly spaced on the mounting plate 5, and the water tanks 18 are in a contracted shape. When the frost on the evaporator 3 melts into water and falls onto the mounting plate 5, the water tanks 18 on the mounting plate 5 are in a contracted shape, effectively collecting water droplets and causing them to fall into the collection frame 17, where they can be collected and recycled.

[0025] Furthermore, a collection box 17 is provided at the bottom of the interior of the freezing chamber 2.

[0026] Working principle: When excessive frost forms on the surface of the evaporator tubes on evaporator 3, the user starts motor 7. The output end of motor 7 drives the rotating rod 8 to rotate, generating airflow that melts the frost on evaporator 3. Simultaneously, the rotation of the rotating rod 8 drives the worm gear 11 to rotate, causing the meshing worm wheel 12 to rotate. The limiting cylinder 9 and the support frame 10 support the worm wheel 12. The rotation of the worm wheel 12 drives the first connecting rod 13 to rotate, and the free end of the first connecting rod 13 drives the second connecting rod 14. Thus, the fan blade 16 swings back and forth while rotating. When the frost on evaporator 3 melts into water and falls onto the mounting plate 5, the water tank 18 on the mounting plate 5 contracts, effectively collecting the water droplets and causing them to fall into the collection frame 17 for recycling. By setting up the drive structure and guide structure, the blowing area of ​​the fan blade 16 can be effectively increased, accelerating the melting rate of the frost on evaporator 3, thereby stabilizing the freezing effect of the cabinet 1.
