Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0032] Please refer to Figures 1 to 4 The utility model provides a refrigeration structure with an anti-deformation pipeline, comprising a freezing cylinder 1, a compressor 2, a heat exchanger 3, a refrigeration cycle pipeline 4 and a heat exchange cycle pipeline 5; the compressor 2 is provided with a condensation outlet 21, a condensation inlet 22, a heat exchange inlet 23 and a heat exchange outlet 24;

[0033] The refrigeration cycle pipeline 4 includes a capillary tube 41, a condensing pipe 42, and a return pipe 43 that are connected in sequence; the capillary tube 41 is connected to the condensing outlet 21; the return pipe 43 includes a first vertical pipe section 431, a first curved pipe section 432, a horizontal section 433, a second curved pipe section 434, a third curved pipe section 435, and a second vertical pipe section 436 that are connected in sequence; the first vertical pipe section 431 is connected to the condensing pipe 42, and the second vertical pipe section 436 is connected to the condensing inlet 22; the condensing pipe 42 is arranged around the outer circumference of the freezing cylinder 1;

[0034] The heat exchange circulation pipeline 5 includes a cold source input pipe 51 and an exhaust pipe 52; one end of the cold source input pipe 51 is connected to the heat exchange inlet 23, and the other end of the cold source input pipe 51 is connected to the heat source input end of the heat exchanger 3, and the cold source input pipe 51 is provided with an expansion valve 511; the exhaust pipe 52 includes a first straight pipe section 521, a connecting pipe section 522, a second straight pipe section 523, a spiral section 524 and a third straight pipe section 525 connected in sequence; the first straight pipe section 521 is connected to the heat exchange outlet 24, and the third straight pipe section 525 is connected to the cold source output end of the heat exchanger 3.

[0035] The refrigeration structure incorporates a return air duct 43 within the refrigeration cycle 4 and an exhaust duct 52 within the heat exchange cycle 5. Each duct features multiple curved sections, forming a flexure-resistant structure. Due to the curved structures, the return air duct 43 and exhaust duct 52 can withstand tensile forces and undergo a certain degree of deformation in the event of vibration during transportation, collision, or dropping during handling, thereby absorbing the effects of vibration and preventing damage to the return air duct 43 and exhaust duct 52.

[0036] The refrigeration principle of the freezing cylinder 1, the compressor 2 and the heat exchanger 3 can refer to the existing ice cream machine.

[0037] Specifically, the first curved pipe section 432 is bent forward, the second curved pipe section 434 is a U-shaped curved pipe, and the third curved pipe section 435 is bent downward.

[0038] In a specific embodiment of the present invention, the first curved pipe section 432 is a forward-curving curved pipe, the second curved pipe section 434 is a U-shaped curved pipe, and the third curved pipe section 435 is a downward-curving curved pipe. The return air pipe 43 is integrally formed. The condensate enters the first vertical pipe section 431 from the condenser pipe 42, and then connects the first vertical pipe section 431 with the horizontal section 433 through the first curved pipe section 432, allowing the condensate to enter the horizontal section 433 from the first vertical pipe section 431. The condensate then connects through the second curved pipe section 434 and the third curved pipe section 435, changing direction so that the horizontal section 433 connects with the second vertical pipe section 436, allowing the condensate to enter the compressor 2.

[0039] Specifically, the connecting pipe section 522 is a U-shaped elbow pipe, and the spiral section 524 is formed by winding the pipe one circle or more, and is in a spiral shape.

[0040] In a specific embodiment of the present invention, the connecting pipe section 522 is a U-shaped bend, which changes the direction of the pipeline, allowing the first straight pipe section 521 and the second straight pipe section 523 to connect through the connecting pipe section 522. The spiral section 524 is a spiral pipeline formed by winding the pipeline once, and the spiral section 524 connects the second straight pipe section 523 and the third straight pipe section 525. This structure can withstand tensile forces.

[0041] Optionally, a bracket 6 is further included, wherein the bracket 6 includes a front support frame 61, a horizontal plate 62, a first support plate 63 and a second support plate 64;

[0042] The upper end of the front support frame 61 is detachably connected to the front end of the horizontal plate 62, and the lower end of the front support frame 61 is detachably connected to the bottom of the external shell; the upper end of the first support plate 63 is detachably connected to the rear end of the horizontal plate 62, and the lower end of the first support plate 63 is detachably connected to the bottom of the external shell; the lower end of the second support plate 64 is connected to the top surface of the horizontal plate 62; the upper end of the second support plate 64 is detachably connected to the top of the external shell;

[0043] The first support plate 63 is provided with a first accommodating cavity, and the heat exchanger 3 is arranged in the first accommodating cavity; the second support plate 64 is provided with a second accommodating cavity, and the second accommodating cavity is used to install the control module of the ice cream machine;

[0044] The outer periphery of the freezing cylinder 1 is provided with a protective shell 11, and the freezing cylinder 1 can be detachably mounted on the horizontal plate 62 through the protective shell 11; the compressor 2 is arranged below the horizontal plate 62; the horizontal plate 62 is provided with a connecting notch 620, and the capillary tube 41 and the return air pipe 43 respectively pass through the connecting notch 620 and are connected to the compressor 2.

[0045] By adopting the above structure, the assembly layout of the bracket 6 is optimized while reducing the number of brackets, and the space is reasonably utilized, so that the installation position of components such as the freezing cylinder 1, the compressor 2 and the heat exchanger 3 is more compact. Moreover, the freezing cylinder 1, the compressor 2 and the heat exchanger 3 are fixed by the bracket 6, which makes them more solid and stable, thereby improving the overall vibration resistance and collision resistance of the refrigeration structure and improving the stability of the refrigeration structure.

[0046] Preferably, the first support plate 63 is provided with a through hole 630 , and a fan 7 is provided on a side of the through hole 630 close to the compressor 2 .

[0047] The fan 7 plays the role of auxiliary heat dissipation. It drives the airflow by rotating the fan blades, draws the air around the compressor 2, and generates airflow, so that the airflow passes through the heat exchanger 3 and is then discharged out of the box. The heat naturally transferred to the surrounding air by the compressor 2 can be quickly carried away by the wind, thereby improving the efficiency of the air flow in carrying away heat and improving the heat dissipation effect of the compressor 2.

[0048] Optionally, the compressor 2 is arranged vertically so that the cylinder center line of the compressor 2 is perpendicular to the horizontal plane.

[0049] In one embodiment of the present invention, compressor 2 is a vertical compressor. With this structure, the centerline of the compressor cylinder is perpendicular to the ground, improving space utilization within the ice cream machine, reducing the width of the machine, and shrinking the overall dimensions of the ice cream machine, thereby reducing the countertop space occupied.

[0050] The utility model also provides an ice cream machine, which adopts the refrigeration structure with the anti-deformation pipeline as mentioned above.

[0051] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific embodiments of the present invention without inventive effort, and such equivalent variations or substitutions are encompassed within the scope of the claims of this application.
