[0001] This application relates to the field of household appliance technology, and in particular to a drain pipe installation structure and a refrigeration device. Background Technology
[0002] In refrigeration units such as refrigerators and freezers, the drain pipe is used to drain defrost water to the outside. The bottom plate of the unit has mounting holes; one end of the drain pipe is fixed to the water outlet inside the unit, and the other end extends through the mounting hole. Because the unit is filled with foaming material, a seal is usually installed between the drain pipe and the bottom plate to prevent leakage of the foaming liquid from the gap between the drain pipe and the wall of the mounting hole.
[0003] However, in actual production, the base plate is usually made of thin iron sheet or plastic sheet, which is easy to deform. When the foaming material expands rapidly through chemical reaction, it will deform the base plate, which will affect the sealing effect of the seal and cause leakage problems. Utility Model Content

[0038] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0040] This application provides a drain pipe installation structure and a cooling device 100 to improve the sealing effect of the drain pipe 2 and avoid leakage caused by the expansion of the foaming material. The following description is in conjunction with the accompanying drawings.
[0041] Please see Figure 1 and Figure 4 The drainage pipe installation structure proposed in this application includes a mounting plate 1, a drainage pipe 2, a sealing element 3, and a fastener 4. The mounting plate 1 has an inner side and an outer side that are disposed opposite to each other, and a mounting hole is provided on the mounting plate 1. The drainage pipe 2 passes through the mounting hole. The sealing element 3 is disposed on the inner side of the mounting plate 1 and surrounds the drainage pipe 2 to seal the gap between the hole wall of the mounting hole and the drainage pipe 2. The fastener 4 is disposed on the drainage pipe 2 and located on the outer side of the mounting plate 1, and the fastener 4 abuts against the mounting plate 1.
[0042] In this context, mounting plate 1 refers to a structural component used to install drain pipe 2, seal 3, etc. In practical applications, when the drain pipe mounting structure of this embodiment is used in a refrigeration unit 100, mounting plate 1 can be the housing or wall panel of the refrigeration unit 100. For ease of description, mounting plate 1 is defined as having an inner and outer side arranged opposite to each other. Mounting holes are provided for the drain pipe 2 to pass through, and their shape can be configured to fit the shape of the drain pipe 2, such as a circular hole. The mounting holes are provided through both the inner and outer sides of mounting plate 1.
[0043] The drain pipe 2 is a tubular structure used for drainage. The drain pipe 2 passes through the mounting hole, so that one end of the drain pipe 2 is located inside the mounting plate 1, and the other end is located outside the mounting plate 1. The drain pipe 2 can be a fitting in the refrigeration unit 100 used for discharging defrost water.
[0044] The seal 3 is used to seal the gap between the mounting hole and the drain pipe 2 to prevent liquid substances (such as water, foaming liquid, etc.) from leaking from the gap. Figure 2 , Figure 5 and Figure 6 As shown, in some embodiments, the sealing element 3 can be a sealing sponge, rubber, silicone, etc. The shape of the sealing element 3 can be an annular structure, and the sealing element 3 is sleeved or wrapped around the outside of the drain pipe 2 to ensure sealing of the gap.
[0045] Please see Figure 3 and Figure 4 Fastener 4 is installed on drain pipe 2 and abuts against mounting plate 1, thereby fixing drain pipe 2. At the same time, fastener 4 is located on the outside of mounting plate 1, so that when mounting plate 1 is subjected to external force from the inside, it can limit the deformation of mounting plate 1 to the outside.
[0046] In the refrigeration device 100 provided in this application, a fastener 4 is provided on one end of the drain pipe 2 located outside the mounting plate 1, and the fastener 4 abuts against the mounting plate 1. The fastener 4 fixes the drain pipe 2 and the mounting plate 1 relative to each other, thereby limiting the deformation of the mounting plate 1 and ensuring that the drain pipe 2 and the mounting plate 1 remain fixed when the foaming deformation occurs. This ensures that the contact between the seal 3 and the mounting plate 1 and the drain pipe 2 is not affected by deformation, thereby ensuring the sealing effect of the seal 3 and avoiding the problem of foam leakage.
[0047] In some embodiments, the drain pipe mounting structure further includes a flange 5, see [link to documentation]. Figure 6 The flange 5 is disposed on the drain pipe 2 and located inside the mounting plate 1, and the sealing element 3 is disposed around the flange 5. Specifically, the drain pipe 2 may include a pipe body and an interface, and the flange 5 is used to connect the pipe body and the interface.
[0048] The fastener 4 can be implemented in various ways. For example, the fastener 4 can be fixedly installed on the drain pipe 2 to fix the drain pipe 2 and prevent the mounting plate 1 from deforming and affecting the seal. Alternatively, the fastener 4 can be a movable part, for example, it can be movably disposed on the drain pipe 2 along its length. In this way, not only can the drain pipe 2 be fixed, but the position of the fastener 4 on the drain pipe 2 can also be adjusted to ensure that the fastener 4 always abuts against the mounting plate 1, improving the fixing and restraining effect. It can be understood that when the fastener 4 is a movable part, its movement on the drain pipe 2 can be unlocked or locked, so that it can be locked in a certain fixed position.
[0049] In one specific embodiment, the fastener 4 can be configured as a C-type clip, which is fixedly installed on the drain pipe 2 to secure the drain pipe 2.
[0050] In another specific embodiment, the fastener 4 is configured as a movable component. Its movement can be sliding or moving along the drain pipe 2. For example, a rack extending along the length of the drain pipe 2 can be provided on the outer wall of the drain pipe 2, and a check gear that meshes with the rack can be provided on the fastener 4, allowing the fastener 4 to engage with the outer wall of the drain pipe 2. The fastener 4 can also be configured to be rotatably fitted onto the drain pipe 2, and to be displaced along the length of the drain pipe 2 during rotation. For example, threads can be provided on the outer wall of the drain pipe 2, allowing the fastener 4 to be threadedly engaged with the outer wall of the drain pipe 2. It can be understood that the threads can be directly formed on the outer wall of the drain pipe 2, or a sleeve with external threads can be fitted onto the drain pipe 2.
[0051] Furthermore, when fastener 4 is configured for rotational mounting, it can also be achieved in the following manner: Please refer to [link / reference]. Figure 8 and Figure 9 In one embodiment, the drain pipe mounting structure further includes a guide portion and a mating portion. The guide portion is disposed on one of the fastener 4 and the drain pipe 2, and the mating portion is disposed on the other of the fastener 4 and the drain pipe 2. For example, the guide portion can be located on the fastener 4, and the mating portion can be located on the drain pipe 2; alternatively, the guide portion can be located on the drain pipe 2, and the mating portion can be located on the fastener 4. The guide portion has a guide slope 431, which is configured to gradually incline towards the mounting plate 1 along the rotation direction of the fastener 4. Figure 8 In this configuration, assuming the fastener 4 is located above the mounting plate 1, when the fastener 4 rotates counterclockwise, the guide slope 431 gradually slopes downwards along the counterclockwise direction. Thus, when the fastener 4 rotates in the same direction, the guide slope 431 engages with the mating part, allowing the mating part to move along the guide slope 431 in the opposite direction to the rotation. This pushes the guide slope 431 towards the mounting plate 1, enabling the fastener 4 to move relative to the drain pipe 2 and move closer to the mounting plate 1, thereby tightening the fastener 4 and fixing the drain pipe 2.
[0052] In one specific embodiment, the fastener 4 includes a ring body 41, with a through hole 42 at its center for the drain pipe 2 to pass through. A guide block 43 protrudes from the side of the ring body 41 opposite to the mounting plate 1. The guide block 43 is arranged circumferentially along the through hole 42, forming the guide portion. The side of the guide block 43 opposite to the mounting plate 1 is configured to gradually incline towards the mounting plate 1 along the rotation direction of the fastener 4, thereby forming the guide slope 431. (See also...) Figure 7 The drain pipe 2 has a protrusion 21, which is located on the side of the guide block 43 away from the mounting plate 1. The protrusion 21 constitutes the mating part. When the fastener 4 is rotated, the protrusion 21 engages with the guide block 43, which can push the fastener 4 to abut against the mounting plate 1, thereby fixing the drain pipe 2 and restricting the deformation of the mounting plate 1 towards the fastener 4.
[0053] Furthermore, the side of the protrusion 21 facing the guide block 43 can also be set as an inclined surface that matches the guide inclined surface 431. For example, it can be an inclined surface that gradually tilts towards the mounting plate 1 along the rotation direction, and the tilt angle of the inclined surface is the same as the tilt angle of the guide inclined surface 431. In this way, the cooperation between the protrusion 21 and the guide inclined surface 431 becomes a relative sliding between surfaces, which improves stability.
[0054] The guide portion can be one or more; correspondingly, the mating portion can also be one or more. "Multiple" refers to two, three, or more. Specifically, multiple guide blocks 43 are provided, arranged circumferentially along the through hole 42; multiple protrusions 21 are provided, and each protrusion 21 corresponds one-to-one with a guide block 43. This ensures that all parts of the ring body 41 in the circumferential direction receive a pushing force, allowing the ring body 41 to move smoothly and stably.
[0055] It is understood that the ring body 41 is generally plate-shaped, and its shape can be various, such as circular, square, polygonal, or floral, and this application does not limit it. The circumferential direction of the ring body 41 refers to the direction along the periphery of the ring body 41 or the direction around the central axis of the ring body 41. For example, for a ring body 41 with a circular configuration, the circumferential direction refers to its circumferential direction.
[0056] To facilitate the installation of the fastener 4, in one embodiment, a through groove 45 is also provided on the wall of the through hole 42, and the through groove 45 is provided through both sides of the ring body 41. The through groove 45 corresponds to the protrusion 21 so that the protrusion 21 can pass through. When installing the fastener 4, the fastener 4 can be put on the drain pipe 2, and the through groove 45 of the fastener 4 is aligned with the protrusion 21. Then, the fastener 4 is moved towards the mounting plate 1 so that the protrusion 21 can pass smoothly through the through groove 45, thereby placing the fastener 4 between the protrusion 21 and the mounting plate 1. Then, the fastener 4 is rotated so that the protrusion 21 and the through groove 45 are no longer aligned, thus preventing the fastener 4 from detaching from the drain pipe 2.
[0057] Considering that the seal 3 may be deformable, in order to facilitate the installation of the seal 3, when installing the fastener 4, a certain installation allowance can be left between the fastener 4 and the protrusion 21. The installation allowance can be a gap of less than or equal to 2mm. In this way, when the seal 3 is installed, the seal 3 will expand and deform to a certain extent, which can push the mounting plate 1 to abut against the fastener 4.
[0058] In one embodiment, the ring body 41 is further provided with a protruding rib 44 on the side opposite to the mounting plate 1, and the protruding rib 44 extends radially along the fastener 4. The protruding rib 44 can strengthen the fastener 4 and also serve as an operating point for rotating the fastener 4, making the operation of rotating the fastener 4 more convenient.
[0059] The ribs 44 can be multiple, and at least two of the multiple ribs 44 are symmetrically arranged with respect to the central axis of the ring body 41. The two ribs 44 symmetrically arranged with respect to the central axis are located on the same diameter of the ring body 41, which facilitates operation and rotation.
[0060] Furthermore, in some embodiments, not only is a through groove 45 provided on the wall of the through hole 42 for the protrusion 21 to pass through, but a rib 44 is also provided on one side of the ring body 41, with the through groove 45 corresponding to the rib 44. In this way, the rib 44 can also serve to position the through groove 45, making it easy to align the through groove 45 with the protrusion 21 when installing the fastener 4, thus helping to reduce the difficulty of installing the fastener 4.
[0061] In addition, please see Figure 1This application also proposes a refrigeration device 100, which can be a refrigerator, freezer, etc. The refrigeration device 100 may include a drain pipe mounting structure, which includes a mounting plate 1, a drain pipe 2, a sealing element 3, and a fastener 4. The specific structure of the drain pipe mounting structure is as described in the above embodiments. Since the drain pipe mounting structure of this refrigeration device 100 adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The mounting plate 1 has an inner side and an outer side arranged opposite to each other, and a mounting hole is provided on the mounting plate 1; the drain pipe 2 passes through the mounting hole; the sealing element 3 is located on the inner side of the mounting plate 1 and surrounds the drain pipe 2 to seal the gap between the hole wall of the mounting hole and the drain pipe 2; the fastener 4 is located on the drain pipe 2 and on the outer side of the mounting plate 1, and the fastener 4 abuts against the mounting plate 1. The drain pipe 2 is fixed relative to the mounting plate 1 by fastener 4, which can limit the deformation of the mounting plate 1 and ensure that the drain pipe 2 and the mounting plate 1 remain fixed when the foam deforms, thereby ensuring the sealing effect of the seal 3 and avoiding the problem of foam leakage.
