Therefore, a refrigeration evaporator assembly is proposed to address the above problems. Utility Model Content

[0014] The present invention relates to a refrigeration evaporator assembly. During long-term use, the refrigeration evaporator may develop frost and ice due to its low surface temperature.

[0023] 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.

[0024] like Figure 1-4 As shown, a refrigeration evaporator assembly includes a base 1; an evaporator body 11 is installed on one side inside the base 1; a blower housing 12 is fixedly connected to one side outside the base 1; a first servo motor 13 is installed inside the blower housing 12; a fan blade 14 is fixedly connected to the output end of the first servo motor 13; a ventilation slot 16 is formed inside the base 1 near the fan blade 14; a heating element 15 is installed on the top of the ventilation slot 16 on the inner side of the base 1; the heating element 15 communicates with the ventilation slot 16; during operation, the evaporator body 11 is installed on the inner side of the base 1 near the blower housing 12, at which time the first servo motor 13 inside the blower housing 12 starts to work, driving the fan blade 14 to rotate, generating airflow, which passes through the ventilation slot 16. The airflow flows towards the evaporator body 11, carrying away heat from the surface of the evaporator body 11 and increasing the cooling effect of the evaporator body 11. When frost appears on the surface of the evaporator body 11, the heating element 15 starts to work and generate heat. Since the heating element 15 is connected to the ventilation slot 16, the airflow generated by the rotation of the fan blade 14 will be heated by the heating element 15, achieving the effect of defrosting the surface of the evaporator body 11 with hot air. During long-term use, the refrigeration evaporator may frost and ice due to its low surface temperature. If the frost is too thick, it will hinder airflow, reduce heat exchange efficiency, and result in poor cooling effect. Therefore, when frost appears on the surface of the evaporator body 11, simply turning on the heating element 15 can achieve the defrosting effect, reducing the impact of thick frost on the cooling effect.

[0025] like Figure 1-4As shown, two sets of baffle plates 2 are slidably connected inside the ventilation slot 16; the baffle plates 2 have threaded grooves 23 inside; a bidirectional screw 22 is threaded inside the threaded grooves 23; a second servo motor 21 is fixedly connected to the top of the outer side of the base 1; the output end of the second servo motor 21 is fixedly connected to the bidirectional screw 22; during normal use, the baffle plates 2 are located inside the ventilation slot 16 on both sides away from the blower housing 12. When it is necessary to defrost the surface of the base 1, the second servo motor 21 is driven to start rotating, which rotates the bidirectional screw 22, causing the two sets of baffle plates 2 to move closer to each other and block the air outlet in the middle of the base 1. The flowing air is heated by the heating element 15 and then blown towards the evaporator body 11. By blocking the air outlet in the middle of the base 1, the airflow generated by the fan blades 14 when rotating is heated by the heating element 15 and blown towards the evaporator body 11, which greatly increases the efficiency of defrosting the surface of the evaporator body 11 and further reduces the impact of thick frost on the cooling effect of the evaporator body 11.

[0026] like Figure 1-2 As shown in Figure 4, a guide plate 3 is provided on the inner side of the base 1; the guide plate 3 is located at the bottom of the evaporator body 11; a guide groove 31 is provided inside the base 1 near the guide plate 3; a drain pipe body 32 is fixedly connected to the outer side of the base 1 near the guide groove 31; the drain pipe body 32 is connected to the guide groove 31; during operation, when defrosting the surface of the evaporator body 11, water stains will be generated due to the melting of frost. When these water droplets fall above the guide plate 3 at the bottom of the base 1, they will flow into the guide groove 31 and be discharged into the base 1 through the drain pipe body 32. Some water stains will appear during the defrosting process. If these water stains are not cleaned in time, they may cause the evaporator body 11 to freeze rapidly during operation. Therefore, the combination of the guide plate 3 and the guide groove 31 discharges the water stains generated by the melting of frost into the base 1, reducing the possibility of the water stains freezing again inside the base 1.

[0027] like Figure 2-3 As shown, a limiting groove 4 is provided on the top inner side of the wind deflector 2; a limiting strip 41 is fixedly connected to the bottom of the wind deflector 2; the limiting strip 41 slides inside the limiting groove 4; during operation, when the two sets of wind deflectors 2 approach each other inside the ventilation slot 16, the limiting strip 41 at the top of one set of wind deflectors 2 slides into the limiting groove 4 at the top of the other set of wind deflectors 2, thereby further improving the stability of the connection between the two sets of wind deflectors 2 by the limiting strip 41 sliding into the limiting groove 4.

[0028] like Figure 2-3As shown, the wind deflector 2 has a sliding groove 5 at the end away from the threaded groove 23; a sliding rod 51 is slidably connected inside the sliding groove 5; during operation, when the wind deflector 2 slides up and down inside the ventilation slot 16, the sliding groove 5 inside the wind deflector 2 also slides outside the sliding rod 51, making the wind deflector 2 more stable during the sliding process. During the sliding process of the wind deflector 2, the stability of the wind deflector 2 during the sliding process is further improved by the cooperation between the sliding groove 5 and the sliding rod 51.

[0029] like Figure 1 , 4 As shown, a support plate 6 is fixedly connected to the middle of the inner side of the base 1; the support plate 6 is located at the bottom of the evaporator body 11; during operation, the support plate 6 is installed on the top of the evaporator body 11 to support the evaporator body 11. Through the support of the support plate 6 on the bottom of the evaporator body 11, the evaporator body 11 remains stable during long-term use, reducing the possibility of deformation at the connection with the base 1.

[0030] like Figure 4 As shown, the blower housing 12 has a dust filter hole 7 on the side away from the evaporator body 11. When the first servo motor 13 drives the fan blade 14 to start working, the dust filter hole 7 filters the air, reducing the possibility of dust in the air being sucked in by the first servo motor 13.

[0031] Working principle: The evaporator body 11 is installed inside the base 1 near the blower housing 12. The first servo motor 13 inside the blower housing 12 then starts working, driving the fan blades 14 to rotate and generate airflow. This airflow flows through the ventilation slots 16 to the evaporator body 11, carrying away heat from the surface of the evaporator body 11 and increasing its cooling effect. When frost appears on the surface of the evaporator body 11, the heating element 15 starts working to generate heat. Because the heating element 15 is connected to the ventilation slots 16, the airflow generated by the rotating fan blades 14 is heated by the heating element 15, achieving the effect of defrosting the surface of the evaporator body 11 with hot air. During long-term use, the refrigeration evaporator will experience frost due to its low surface temperature. The possibility of frost and ice formation exists. Excessive frost can obstruct airflow, reduce heat exchange efficiency, and result in poor cooling. Therefore, when frost appears on the surface of the evaporator body 11, simply opening the heating element 15 will achieve defrosting, reducing the impact of thick frost on cooling performance. During normal use, the baffles 2 are located inside the ventilation slot 16, away from the blower housing 12 on both sides. When defrosting of the base 1 surface is required, the second servo motor 21 is driven to rotate, rotating the bidirectional screw 22, causing the two sets of baffles 2 to move closer together, blocking the air outlet in the middle of the base 1. This allows the flowing air to be heated by the heating element 15 before being blown towards the evaporator body 11. By blocking the air outlet in the middle of the base 1, the airflow generated by the rotating fan blades 14 is forced to pass through... The heating element 15 blows heat towards the evaporator body 11, greatly increasing the efficiency of defrosting the surface of the evaporator body 11 and further reducing the impact of thick frost on the cooling effect of the evaporator body 11. During defrosting, the melting of frost produces water stains. These water droplets fall onto the guide plate 3 at the bottom of the base 1 and flow into the guide channel 31, then drain out of the base 1 through the drain pipe 32. Some water stains will appear during the defrosting process. If these water stains are not cleaned in time, they may cause the evaporator body 11 to freeze rapidly during operation. Therefore, the combination of the guide plate 3 and the guide channel 31 drains the water stains generated by the melting frost into the base 1, reducing the risk of water stains freezing again inside the base 1. To improve the stability of the connection between the two sets of baffles 2, when they approach each other inside the ventilation slot 16, the limiting strip 41 at the top of one set of baffles 2 slides into the limiting groove 4 at the top of the other set of baffles 2. This sliding of the limiting strip 41 into the limiting groove 4 further enhances the stability of the connection. When the baffles 2 slide up and down inside the ventilation slot 16, the sliding groove 5 inside the baffles 2 also slides outside the sliding rod 51, making the baffles 2 more stable during sliding. The cooperation between the sliding groove 5 and the sliding rod 51 further improves the stability of the baffles 2 during sliding. The support plate 6 is installed on top of the evaporator body 11 to support it, and also supports the bottom of the evaporator body 11.This ensures the stability of the evaporator body 11 during long-term use, reducing the possibility of deformation at the connection with the base 1. When the first servo motor 13 drives the fan blades 14 to start working, the dust filter 7 filters the air, reducing the possibility of dust in the air being sucked into the first servo motor 13.
