Detailed Description

The utility model discloses at first provide a drain pipe for refrigerator, figure 1 is according to the utility model discloses a schematic structure chart of a drain pipe for refrigerator of embodiment, figure 2 is according to the utility model discloses a schematic structure of a drain pipe for refrigerator of embodiment decomposes the view. Referring to fig. 1 and 2, the drain pipe 40 includes a main pipe body 41 for communicating with a drain port of the refrigerator, a connection pipe body 42 connected to the main pipe body 41 and extending in a bent state, and a locking member 43 for locking the main pipe body 41 and the connection pipe body 42. The main pipe body 41 and the connection pipe body 42 are limited by the plugging structure, and the plugging structure is configured to limit the relative position of the connection pipe body 42 and the main pipe body 41 in the circumferential direction of the main pipe body 41, that is, the plugging structure is used to limit the matching freedom degree of the main pipe body 41 and the connection pipe body 42 in the circumferential direction, and the connection pipe body 42 is prevented from rotating relative to the main pipe body 41.

The utility model discloses a drain pipe 40 for refrigerator is including being responsible for body 41 and connecting tube body 42, accomplishes the back at the refrigerator foaming for be in the foaming in situ with being responsible for body 41 of refrigerator outlet intercommunication usually, its position and state all can not change usually. The connection pipe body 42 is generally connected to the main pipe body 41 after the foaming of the refrigerator, and thus, the assembly problem of the drain pipe 40 is mainly the assembly between the connection pipe body 42 and the main pipe body 41.

Therefore, the utility model discloses it is spacing to be responsible for body 41 and connecting tube body 42 through the grafting structure, can be through the grafting structure on the circumference of being responsible for body 41 limit connecting tube body 42 and the relative position who is responsible for body 41, from this, grasp its position more easily when assembly connecting tube body 42, the orientation etc. need not artifical the correction, treat that connecting tube body 42 assembles to being responsible for behind the body 41 reuse retaining member 43 with the two locking connection can effectively connect body 43 and drop from being responsible for the body, be applicable to very much the little space installation.

Specifically, the locking member 43 is preferably a locking band, a binding band, or the like, which is simple in structure, and very convenient in locking operation, and is suitable for small space operation.

In some embodiments, the plugging structure comprises a cylindrical positioning member 441 and a first recess 442 for cooperating with the cylindrical positioning member 441. The cylindrical positioning member 441 protrudes and extends along the radial direction of the drainage pipe 40, and the first groove 442 is opened with a notch facing the axial direction of the drainage pipe 40, so that the cylindrical positioning member 441 can be inserted into the first groove 442 along the axial direction of the drainage pipe 40.

Since the cylindrical positioning element 441 protrudes and extends radially outward, it is obvious that an operator can easily find the relative position between the first groove 442 and the cylindrical positioning element 441 to insert the connecting tube 42 into the main tube 41, the operation is very easy, and the position and the orientation of the connecting tube 42 are both limited, so as to achieve the initial positioning of the connecting tube 42.

Further, the two first sidewalls 445 defining the first groove 442 are two first circular arc-shaped sections located on the same circumference. Therefore, after the connecting pipe 42 is inserted into the main pipe 41, the two first sidewalls 445 can be tightly attached to the wall of the main pipe 41, so that not only can the assembly effect be further enhanced, but also a certain reinforcing and sealing effect can be achieved, and the leakage of condensed water can be prevented.

In some embodiments, the plugging structure further comprises a strip-shaped positioning rib 443 and a second groove 444 for cooperating with the strip-shaped positioning rib 443. The bar-shaped positioning rib 443 extends along the axial direction of the drain pipe 40, and the second groove 444 is opened with a notch facing the axial direction of the drain pipe 40, so that the bar-shaped positioning rib 443 is inserted into the second groove 444 along the axial direction of the drain pipe 40. Because the strip-shaped positioning rib 443 and the second groove 444 both extend along the axial direction of the drain pipe 40, the matching of the strip-shaped positioning rib 443 and the second groove 444 can also have a certain limiting effect on the position and the orientation of the connecting pipe body 42, and the positioning of the connecting pipe body 42 in the circumferential direction is realized.

Further, the two second side walls 446 defining the second groove 444 are two second circular arc-shaped sections located on the same circumference. Therefore, after the connecting pipe 42 is inserted into the main pipe 41, the two second side walls 446 can be tightly attached to the pipe wall of the main pipe 41, so that the assembling effect can be further enhanced, a certain reinforcing and sealing effect can be achieved, and the leakage of condensed water is prevented.

In some embodiments, the elongated positioning ribs 443 are generally elongated, strip-shaped structures having a relatively small width in the circumferential direction of the drain pipe 40. The outer diameter of the cylindrical positioning member 441 is larger than the width of the strip-shaped positioning rib 443, and the widths of the first groove 442 and the second groove 444 are respectively matched with the outer diameter of the cylindrical positioning member 441 and the width of the strip-shaped positioning rib 443. That is, the width of the first groove 442 is greater than the width of the second groove 444. Note that the width here refers to a dimension in the circumferential direction of the drain pipe.

The utility model discloses a grafting structure includes two sets of cooperation mechanisms, and one set is cylindrical positioning element 441 and first recess 442's location fit, and another set is bar location muscle 443 and second recess 444's location fit. The cylindrical positioning member 441 has a larger size, and the strip-shaped positioning rib 442 has a smaller width, that is, the fitting between the cylindrical positioning member 441 and the first groove 442 is equivalent to roughly pre-positioning the connecting tube 42, and the fitting between the strip-shaped positioning rib 443 and the second groove 444 is equivalent to finely positioning after the pre-positioning. The fitting efficiency and the fitting effect of the connecting pipe body 42 can be effectively improved by the cooperation of the pre-positioning and the fine positioning.

Furthermore, the two first circular arc-shaped sections and the two second circular arc-shaped sections are located on the same circumference, and the central angle corresponding to the first circular arc-shaped sections is larger than the central angle corresponding to the second circular arc-shaped sections. That is, the width of the first sidewall 445 in the circumferential direction is larger than the width of the second sidewall 446 in the circumferential direction.

Since the outer diameter of the cylindrical positioning member 441 is greater than the width of the strip-shaped positioning rib 443, the width of the first sidewall 445 for limiting the cylindrical positioning member 441 in the circumferential direction is greater, so as to enhance the structural strength of the first sidewall 445 and prevent the first sidewall 445 from being deformed or broken by force. The strip-shaped positioning ribs 43 are elongated ribs, so that the requirement for limiting the strip-shaped positioning ribs 43 can be met only by the narrow second side walls 446.

In some embodiments, the cylindrical positioning member 441, the positioning rib 443, the first recess 442 and the second recess 444 are positioned and sized such that the cylindrical positioning member 441 and the first recess 442 are engaged with the second recess 444 before the positioning rib 443 is engaged with the second recess 444 when the main tube body 41 and the connecting tube body 42 are assembled. That is, when the main pipe body 41 and the connecting pipe body 42 are assembled, the cylindrical positioning rib 441 is first brought into contact with the first groove 442 and inserted into the first groove 442, and then the bar-shaped positioning rib 443 is brought into contact with the second groove 444 and inserted into the second groove 444. That is, the connecting pipe body 42 is roughly pre-positioned and then finely positioned, which is very advantageous for the assembly of the connecting pipe body 42 and improves the assembly efficiency of the drain pipe 40.

In some embodiments, one of the end sections of the connecting tube 42 is sleeved outside the end section of the main tube 41 to increase the mating surface therebetween and enhance the sealing performance therebetween. Further, a cylindrical positioning member 441 and a bar-shaped positioning rib 443 are formed on the outer tube wall of the main tube 41. Both the two first side walls 445 for defining the first groove 442 and the two second side walls 446 for defining the second groove 444 extend axially outward of the connecting pipe body 42 from the connecting end portion of the connecting pipe body 42 for connection with the main pipe body 41.

In other embodiments, the cylindrical positioning member 441 and the strip-shaped positioning ribs 443 may be formed on the outer pipe wall of the connecting pipe body 42, and accordingly, the first side wall 445 and the second side wall 446 may each extend from the end portion of the main pipe body 41 to the axially outer side of the main pipe body 41.

In some embodiments, the ends of the cylindrical positioning member 441 are flush with the ends of the strip-shaped positioning ribs 443. The two first side walls 445 defining the first groove 442 have a length in the axial direction of the connecting pipe body 42 larger than the two second side walls 446 defining the second groove 444 in the axial direction of the connecting pipe body 42 so that the first side walls 445 first contact the cylindrical positioning member 441 and then the second side walls 446 contact the strip-shaped positioning ribs 443 during the assembly of the connecting pipe body 42 to the main pipe body 41, thereby satisfying the purpose of roughly pre-positioning the connecting pipe body 42 and then finely positioning it.

In some embodiments, the connection pipe 42 is bent and extended downward from the main pipe 41 from front to rear to form a downward drain port at the extended end of the main pipe 41, thereby facilitating the formation of a water seal between the drain port and the evaporation pan of the refrigerator.

Further, the cylindrical positioning member 441 is disposed on the outer wall of the side portion of the main pipe body 41, and the strip-shaped positioning ribs 443 are disposed on the outer wall of the top portion of the main pipe body 41, so that on one hand, an operator can assemble the connecting pipe body 42 conveniently, and on the other hand, the downward orientation of the drainage port of the connecting pipe body 42 can be ensured.

In some embodiments, the main tube 41 is a hard tube and the connecting tube 42 is a flexible tube. It should be noted that the term hose does not merely mean that the hose is flexible, and for ease of understanding, a hose is defined herein as a tube that can be bent or stretched or compressed to some extent along its length without failing. "to some extent" means that the connecting tube body 42 can be deformed at least as described above.

Specifically, the connection pipe body 42 may be specifically a heat-resistant rubber pipe or a resin pipe. In particular, it may be a corrugated tube, and the material of the corrugated tube may be heat-resistant polyethylene (i.e. PE corrugated tube), or even a metal material with high plasticity, so as to ensure that the corrugated tube will not deform and age due to high temperature when working in the environment in the compressor chamber.
