Description

Technical Field

[0001] The utility model relates to the technical field of evaporator structures, and specifically relates to an evaporator structure for a refrigerator. Background Art

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a household product that keeps food or other items in a constant low temperature state. Since it can be used for food preservation and storage, the refrigerator is a very common household appliance. The means for the refrigerator to preserve food is through refrigeration, so the evaporator has become a very important component during the refrigeration process;

[0003] Among them, the evaporator is a key component in the refrigeration system. Its main function is to absorb heat through the evaporation of liquid refrigerant, thereby achieving the refrigeration effect. Each type of evaporator has different structures and applications to meet different refrigeration requirements. Each evaporator needs to be equipped with multiple groups of pipes. When the pipes extend, if their positions are not stable enough, it will directly affect the service life of the pipes. Content of the Utility Model

[0004] The purpose of the utility model is to provide an evaporator structure for a refrigerator, so as to solve the problem that each evaporator needs to be equipped with multiple groups of pipes. When the pipes extend, if their positions are not stable enough, it will directly affect the service life of the pipes as mentioned in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An evaporator structure for a refrigerator, including a support bottom plate, a compressor main body, and an evaporator main board. The front end face of the evaporator main board is distributed with evaporator pipes. A fan is assembled at the right side position inside the evaporator main board. The tail end of the evaporator pipe is connected to a third pipe, and the third pipe is distributed at the back end position of the evaporator main board. A second hinge seat is assembled on one side of the back end of the evaporator main board. A connecting block is connected to the outside of the second hinge seat. A limiting ring is connected to the side of the connecting block. An extension plate is connected to the side of the limiting ring. A first hinge seat is assembled at the back end of the evaporator main board. A pressing plate is connected to the bottom of the first hinge seat, and mounting holes are opened inside the bottom of the pressing plate.

[0006] Preferably, a rotatable connection is formed between the connecting block and the second hinge seat, and a rotatable connection is formed between the first hinge seat and the pressing plate.

[0007] Preferably, bolts are assembled between the pressing plate and the evaporator main board, and the bolts are connected and assembled through the positions of the mounting holes.

[0008] Preferably, a protective pad is fixed to the back end of the limiting ring, and an adhesive connection is formed between the limiting ring and the protective pad.

[0009] Preferably, a coiled pipe is connected to the side of the compressor body. A support rod is fixed to the front end face of the coiled pipe, and a spiral thin copper pipe is connected to the tail end of the coiled pipe.

[0010] Preferably, the tail end of the spiral thin copper pipe is connected to a first pipe. The tail end of the first pipe is connected to a filter. The top of the filter is connected to a second pipe, and the second pipe communicates with one end of the evaporator pipe.

[0011] Preferably, the support rods are evenly distributed on the front end face of the coiled pipe, and an anti-corrosion coating is applied to the outer side wall of the support rods.

[0012] Preferably, a first reinforcing rod is fixed inside the support rod. A second reinforcing rod is connected between the two first reinforcing rods, and the first reinforcing rods are evenly distributed inside the support rod.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: This evaporator structure for refrigerators not only improves the limiting ability, but also improves the support stability and flow filtering ability of the evaporator at the same time;

[0014] By assembling the evaporator pipe at the front end position of the evaporator main board, and the third pipe is connected and located at the back end position of the evaporator main board. At this time, the second hinge seat is assembled at the back end position of the evaporator main board, and a rotatable design is formed after the second hinge seat is assembled with the connecting block. Therefore, after the third pipe is connected, the orientation of the limiting ring can be adjusted, so that the limiting ring can be located outside the third pipe and directly contact with the protective pad to form limiting protection. After the limiting ring is assembled, the extension plate reaches the position below the first hinge seat. At this time, after the adjusting pressure plate is turned down, the pressure plate limits and presses the extension plate, and then the position is locked by bolts at the position of the mounting hole, thereby improving the overall limiting ability;

[0015] By evenly distributing the support rods at the front end position of the coiled pipe, the coiled pipe is supported and reinforced by the support rods. An anti-corrosion coating is applied to the outer side wall of the support rods, so the anti-corrosion coating forms a certain anti-corrosion protection. At the same time, the first reinforcing rods are evenly distributed inside the support rods. Under the distribution of the first reinforcing rods and the second reinforcing rods, the service strength of the support rod is improved, so the overall support stability is improved during the working process;

[0016] After the compressor body works, it compresses the refrigerant and circulates through the coiled pipe for the first cooling. Then, after flowing through the spiral thin copper pipe in a circular manner, it is cooled for the second time. Then, it reaches the filter through the first pipe for filtering to reduce its impurity content. Immediately afterwards, it is connected to the evaporator pipe through the second pipe for subsequent circulation work, thereby improving the overall filtering ability during the working circulation.

A first hinge seat 13 is assembled at the back end of the evaporator main board 12. A pressing plate 17 is connected to the bottom of the first hinge seat 13. An installation hole is opened inside the bottom of the pressing plate 17.

[0024] A rotatable connection is formed between the connecting block 16 and the second hinge seat 15, and a rotatable connection is formed between the first hinge seat 13 and the pressing plate 17.

[0025] A bolt is assembled between the pressing plate 17 and the evaporator main board 12, and the bolt is connected and assembled through the position of the mounting hole.

[0026] A protective pad 19 is fixed to the back end of the limit ring 14, and an adhesive connection is formed between the limit ring 14 and the protective pad 19.

[0027] A coiled pipe 3 is connected to the side of the compressor main body 2. A support rod 4 is fixed to the front end face of the coiled pipe 3, and a spiral thin copper pipe 5 is connected to the tail end of the coiled pipe 3.

[0028] The tail end of the spiral thin copper pipe 5 is connected to a first pipe 6. The tail end of the first pipe 6 is connected to a filter 7. The top end of the filter 7 is connected to a second pipe 8, and the second pipe 8 communicates with one end of the evaporator pipe 11.
