[0024] See also Figure 1-6 The utility model provides a technical solution: a water chiller which is convenient for pipeline maintenance and flushing, comprising a body 1 and a maintenance device 5, a fan 2 is installed above the body 1, a water inlet pipe 3 and a water outlet pipe 4 are respectively installed on one side surface of the body 1, and the maintenance device 5 is arranged on the surface of the water inlet pipe 3.

[0025] The specific configuration and functions of the maintenance device 5 and the cleaning component 57 will be described in detail below.

[0026] Specifically, the maintenance device 5 includes an auxiliary pipe 51, which is arranged at one end of the water inlet pipe 3. A filter 58 is installed on the inner wall of the auxiliary pipe 51. A plug 52 is fixedly connected to the end of the auxiliary pipe 51 close to the water inlet pipe 3. The plug 52 is plugged into the inner wall of the water inlet pipe 3. A fixed sleeve 59 is fixedly connected to the surface of the plug 52. Three blocks 513 are fixedly connected to the inner wall of the fixed sleeve 59. A connecting ring 55 is fixedly connected to the surface of the water inlet pipe 3. A card groove is provided on the surface of the connecting ring 55. A cleaning component 57 is installed on the surface of the filter 58.

[0027] In this embodiment: the fixing sleeve 59 can be sleeved in the connecting ring 55, and the block 513 can be inserted into the groove on the surface of the connecting ring 55. Then, the fixing sleeve 59 is rotated, and the block 513 abuts against the inner wall of the groove, and the auxiliary pipe 51 can be installed. The auxiliary pipe 51 cooperates with the filter element 58 to filter the liquid input into the water inlet pipe 3 and intercept impurities in the auxiliary pipe 51. When maintaining the pipeline later, it is only necessary to disassemble the auxiliary pipe 51 for flushing, so as to avoid a large amount of stains entering the internal pipeline of the chiller, which will cause the problem of trouble in subsequent flushing.

[0028] Specifically, a support ring 54 is fixedly connected to the inside of the water inlet pipe 3 , and a sealing gasket 53 is fixedly connected to one end of the plug 52 .

[0029] In this embodiment: when the plug 52 is inserted into the water inlet pipe 3, the plug 52 can drive the sealing gasket 53 to be squeezed on the support ring 54, thereby sealing. At the same time, when the sealing gasket 53 is squeezed, the stability of the card block 513 in the card slot can also be improved.

[0030] Specifically, the interior of the fixed sleeve 59 is slidably connected with a push ring 510, and one side surface of the push ring 510 is fixedly connected with three insertion rods 512. One end of the insertion rod 512 passes through the fixed sleeve 59. The surface of the connecting ring 55 is fixedly connected with a convex ring 56. The surface of the convex ring 56 is provided with three circular holes for the insertion of the insertion rods 512. The push ring 510 drives the insertion rods 512 to be inserted into the circular holes on the surface of the convex ring 56, which can realize the positioning of the whole and improve the stability effect.

[0031] Specifically, the inner wall of the fixing sleeve 59 is sleeved with a spring 511 , and two ends of the spring 511 are fixedly connected to the push ring 510 and the inner wall of the fixing sleeve 59 , respectively.

[0032] In this embodiment, the spring 511 can push the push ring 510 and the insertion rod 512 to reset, thereby improving the stability of the insertion rod 512 inserted in the circular hole on the surface of the convex ring 56.

[0033] Specifically, the cleaning assembly 57 includes a cylindrical rod 571, which is arranged on the inner wall of the auxiliary tube 51. One end of the auxiliary tube 51 is fixedly connected with a screw 574, which is plugged into the inner wall of the filter element 58. The surface of the cylindrical rod 571 is rotatably connected with two support frames 572, and the corresponding sides of the two support frames 572 are fixedly connected with a scraper 573. The support frame 572 is rotated on the surface of the cylindrical rod 571, and the support frame 572 can drive the scraper 573 to rotate, thereby facilitating subsequent flushing and cleaning.

[0034] Specifically, a nut 575 is threadedly connected to the surface of the screw rod 574 .

[0035] In this embodiment, the nut 575 on the screw rod 574 is rotated. When the nut 575 abuts against the surface of the filter element 58, the cylindrical rod 571 can be positioned to facilitate subsequent disassembly.

[0036] Working principle: by setting the maintenance device 5 and the cleaning component 57, when the equipment is taking in water through the water inlet pipe 3, the auxiliary pipe 51 cooperates with the filter element 58 to filter the water and intercept some impurities. When the pipes in the equipment need to be flushed after long-term use, it is only necessary to remove the auxiliary pipe 51, push the push ring 510 and the insertion rod 512 to the side away from the water inlet pipe 3, the spring 511 is stressed, and the insertion rod 512 is moved out of the circular hole on the surface of the convex ring 56, and then the fixing sleeve 59 is rotated, and the fixing sleeve 59 drives the block 513 to rotate, and the block 513 loses the restraint on the groove on the surface of the connecting ring 55, and then the auxiliary pipe 51 is pulled to the side away from the water inlet pipe 3, and the fixing sleeve 59 and the block 513 are moved out of the connecting ring 55, and the auxiliary pipe can be removed. 51 is disassembled. When the auxiliary pipe 51 is disassembled for flushing, the support frame 572 can be rotated on the cylindrical rod 571, and the support frame 572 drives the two scrapers 573 to scrape off the dirt on the inner wall of the auxiliary pipe 51, so as to facilitate subsequent flushing. By setting the maintenance device 5, it is convenient to reduce the entry of stains into the internal pipeline of the equipment. When flushing the pipeline, only one end needs to be disassembled and flushed, which can effectively reduce the existing chiller. When used for a long time, a large amount of impurities are easily attached to the inside of the pipeline, and regular flushing is required. However, when flushing, a cleaning agent needs to be added to the liquid, starting from one end of the pipeline and gradually flushing to the other end, which leads to troublesome operation, poor flushing effect at the bend of the pipeline, and relatively large waste water problem, thereby improving the overall usability of the equipment.
