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, and figure 3 is according to the utility model discloses a schematic cross-sectional view of the drain pipe of an embodiment. Referring to fig. 1 to 3, a drain pipe 40 for a refrigerator of the present invention includes a pipe body portion 41 and a sleeve 42.

Fig. 4 is a schematic structural view of a sleeve according to an embodiment of the present invention, fig. 5 is a schematic cross-sectional view of the sleeve according to an embodiment of the present invention, and fig. 6 is a schematic enlarged view of a portion C in fig. 3. The tube portion 41 is used for communicating a drain outlet of the refrigerator with an evaporation pan of the refrigerator, so that water discharged from the drain outlet of the refrigerator flows along the tube portion 41 toward the evaporation pan of the refrigerator. The sleeve 42 is sleeved with the end of the tube body 41, which is used for communicating with the evaporation pan, and the sleeve 42 has an open end 421 for allowing water to flow therein, a closed end 422 disposed opposite to the open end 421, a first section 423 overlapping with the tube body 41 in the radial direction, and a second section 424 connected between the first section 423 and the closed end 422, a slit 425 is opened on a circumferential side wall of the second section 424, and the slit 425 is configured to allow water flowing into the sleeve 42 to flow out through the slit 425 and prevent outside air from flowing into the sleeve 42 through the slit 425.

The utility model discloses a drain pipe 40 for refrigerator includes body 41 and cup joints at the terminal sleeve 42 of body 41, and sleeve 42 includes opens end 421, blind end 422, first district 423 and second district 424, and first district 423 radially overlaps with body 41, and from this, the water that flows into body 41 from the refrigerator outlet can flow to sleeve 42's second district 424, has increased the cooperation area between sleeve 42 and the body 41 to avoid the fluid to reveal.

Further, a slot 425 is formed in a circumferential side wall of the second section 424, and the slot 425 can allow water flowing into the sleeve 42 to flow out through the slot 425 and prevent external air from flowing in through the slot 425. Specifically, when the water in the second section 424 is high, the water flows out through the slot 425 under the action of gravity and is discharged into the evaporating dish of the refrigerator; when there is less water in the second section 424, the water collects under its surface tension at the slot 425 to form a water film, thereby preventing outside air from entering the drain pipe 40. It can be seen that the utility model discloses a design simple structure's sleeve 42 very much on drain pipe 40, realized drain pipe 40's self-sealing under the prerequisite that does not influence drain pipe 40's drainage function, gained unexpected technological effect.

It will be appreciated that the surface tension of the water will only act to form a film of water if the width of the slot 425 is limited to a certain small range. If the width of the slot 425 is too large, a water film may not be formed at all at the slot 425. However, if the width of the slot 425 is too small, the water in the sleeve 42 is difficult to flow out of the slot 425, or the flow rate is slow, so that the condensed water is easily accumulated at the drain port of the refrigerator using the drain pipe 40 to cause an ice blockage phenomenon. Thus, the width of the slot 425 has certain dimensional limitations.

Specifically, the width of the slot 425 may be anywhere from 0.8mm to 1.4mm, with best results. For example, the width of the slot 425 may be 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, or 1.4mm.

In some embodiments, the slot 425 is an arc-shaped slot extending along the circumferential direction of the sleeve 42, so that the length of the slot 425 can be properly extended under the condition that the width of the slot 425 is limited, so as to discharge water more smoothly, and further avoid the ice blockage phenomenon of the refrigerator water outlet using the water discharge pipe 40.

In some embodiments, slot 425 is adjacent the end face of closed end 422 to form an overhanging flap 426 at closed end 422. That is, a portion of the edge of the tab 426 is connected to the second segment 424 and another portion of the edge is spaced from the second segment 424 by the slot 425. In other words, the portion of the suspension 426 located inside the other portion of the edge thereof has a certain deformation space on both sides in the axial direction to facilitate elastic deformation of the suspension 426.

Further, the thickness of the suspension 426 is configured to allow elastic deformation of the suspension 426 in a direction away from the slot 425 when water flows through the body portion 41. That is, under the impact or squeezing action of the water flow, the suspension 426 can elastically deform to a certain extent, so that the width of the slot 425 is increased, which is beneficial to the drainage of the condensed water in the drainage pipe 40. When no water flows through the pipe body 41, the acting force applied to the suspension 426 is smaller than the elastic deformation restoring force, the suspension 426 restores the deformation, the width size of the slot 425 restores, and a small amount of water remained around the suspension forms a water film at the slot 425, so that the automatic sealing effect is achieved.

It will be appreciated that the suspension 426 is elastically deformable by the impact or squeezing of water only if its thickness is within a certain range. If the thickness of the suspension 426 is too large, a large force is required to deform the suspension 426, and the water flow effect is not enough to deform the suspension 426 at all; if the thickness of the suspension 426 is too small, the suspension 426 has too small a structural strength and is easily broken during deformation, i.e., deformation recovery. Therefore, the thickness of the suspension 426 has a certain limit.

Specifically, the thickness of the suspension 426 may be anywhere from 0.8 to 1.4mm, with the best results. For example, the thickness of the suspension 426 may be 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, or 1.4mm.

Further, the length of the slot 425 may also affect the elastic deformation of the suspension 426. If the length of the slot 425 is too short, the suspension 426 is not easily deformed if the suspended portion that can be elastically deformed is too small. However, if the length of the slot 425 is too long, the suspension 426 has too large suspended portion capable of generating elastic deformation, and the portion of the suspension 426 connected to the second segment 424 is smaller, the connection strength of the suspension 426 is smaller, and the suspension 426 is easily unable to recover deformation or even break during the elastic deformation.

For this reason, in some embodiments, the central angle of the slot 425 may be any angle in the range of 260 ° to 280 °, which is most effective. For example, slots 425 may correspond to a central angle of 260 °, 262 °, 264 °, 266 °, 268 °, 270 °, 272 °, 274 °, 276 °, 278 °, or 280 °.

It will also be appreciated that the water within the sleeve 42 will generally flow along the bottom or lower portion of the sleeve 42, and will only contact the upper or top portion of the sleeve 42 when the volume of water is greater. To this end, in some embodiments, the present invention provides a slot 425 through a lower portion of the second section 424. Therefore, when a small amount of condensed water is contained in the sleeve 42, the condensed water can easily cover all sections of the slot 425 under the action of the surface tension of the condensed water, a relatively complete water film is formed, and the sealing effect is improved.

In some embodiments, the slot 425 extends from a first location point 4241 on the second segment 424 to a second location point 4242 on the second segment 424, the first location point 4241 and the second location point 4242 being at the same height. That is, the slits 425 are symmetrical about a vertical plane passing through the axial center of the sleeve 42 to more uniformly discharge the condensed water.

It should be noted that in alternative embodiments, the slots 425 may have other suitable shapes or other suitable arrangements.

In some embodiments, the sleeve 42 is sleeved outside the end of the body portion 41. The first section 423 is formed with an axially extending positioning groove 4231, the body portion 41 is formed with an axially extending bar-shaped positioning rib 411, and the bar-shaped positioning rib 411 is inserted into the positioning groove 4231 to limit the position of the sleeve 42 relative to the body portion 41 in the circumferential direction of the drain pipe 40. That is, the engagement of the strip-shaped positioning ribs 411 and the positioning grooves 4231 can restrict the degree of freedom of the sleeve 42 in the circumferential direction, preventing the sleeve 42 from rotating relative to the tube body portion 41.

It will be appreciated that when the drain pipe 40 is assembled to the refrigerator, a part of the body portion 41 thereof is located in the foaming layer of the refrigerator, and the position thereof is not easily changed. The sleeve 42 is assembled to the body portion 41 after other parts of the refrigerator are assembled, and thus, the assembly problem of the drain pipe 40 is the assembly problem between the body portion 41 and the sleeve 42. Therefore, the utility model discloses a constant head tank 4231 and bar location muscle 411 fix a position sleeve 42, from this, grasp its position, orientation etc. more easily when assembling sleeve 42, need not artifical the correction, are applicable to very much the little space installation.

Further, the relative positions of the positioning groove 4231 and the slot 425 are set such that the slot 425 is located at the lower portion of the sleeve 42 after the sleeve 42 is sleeved on the pipe body portion 41. That is, the slot 425 can be indirectly positioned by the positioning between the positioning groove 4231 and the strip-shaped positioning rib 411, and the slot 425 is ensured to be positioned at the lower part of the circumferential side wall of the second section 424, so that the outflow of condensed water is facilitated, and the water film sealing at the slot 425 is facilitated.

In some embodiments, the first section 423 further defines at least one locking groove 4232, the body portion 41 defines at least one locking buckle 412, and the at least one locking buckle 412 is locked into the at least one locking groove 4232 along the axial direction of the drain pipe 40, so as to limit the position of the sleeve 42 relative to the body portion 41 in the circumferential direction and the axial direction. That is, the sleeve 42 and the body portion 41 are also limited by the engagement of the snap groove 4232 and the catch 412, and the relative position of the sleeve 42 and the body portion 41 can be limited in the circumferential direction and the axial direction by the snap groove 4232 and the catch 412, so that the sleeve 42 is prevented from falling off from the body portion 41.

When the drain pipe 40 is installed, the sleeve 42 can be installed on the pipe body portion 41 only by matching the clamping groove 4232 with the buckle 412, complex installation operation is not needed, the assembly process of the drain pipe 40 is simplified, and the assembly efficiency is improved. Moreover, before the card slot 4232 and the buckle 412 are matched, the sleeve 42 can be pre-positioned through the matching of the strip-shaped positioning rib 411 and the positioning groove 4231, so that the card slot 4232 and the buckle 412 can be aligned and matched quickly, and the assembly efficiency is further improved.

Further, the number of the snap grooves 4232 and the number of the snaps 412 are both two. The two locking grooves 4232 are respectively located at two circumferential sides of the positioning groove 4231. Accordingly, two snaps 412 are respectively located at both circumferential sides of the bar-shaped positioning rib 411.

In some embodiments, the sleeve 42 is a rubber sleeve made of a rubber material. Rubber has good elastic deformation and deformation restorability, and thus is very suitable as a material of the sleeve 42.

In alternative embodiments, the sleeve 42 may also be made of resin or other suitable material.
