Detailed Implementation

[0032] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0033] It should be understood that terms such as “above,” “over,” “below,” and “under” used herein to indicate spatial relative position are for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms “spatial relative position” may be intended to include different orientations of the equipment in use or operation other than those shown in the figures.

[0034] One embodiment of this utility model provides a freezer that is easy to install with a drain pipe and has good sealing performance.

[0035] A freezer 100 of this embodiment, such as Figure 1 As shown, it includes an inner liner 10, a compressor compartment 20, and a drain pipe 30. The inner liner 10 is the core component of the freezer 100, which can be used to house the evaporator compartment 12, store items, and other related components.

[0036] The inner liner 10 includes a stepped section 11, which is composed of a bottom wall 111 and a side wall 112. The evaporator compartment 12 is located inside the inner liner 10, and its bottom is provided with a drain outlet 13 for draining defrost water.

[0037] The compressor compartment 20 is located outside the inner liner 10, below the step 11, and is arranged horizontally alongside the evaporator compartment 12. This horizontal arrangement design breaks through the limitation of the traditional vertical arrangement of the evaporator compartment 12 and compressor compartment 20 in the freezer 100, effectively optimizing the space utilization of the freezer 100.

[0038] To clearly illustrate the position and orientation in this embodiment, up and down are defined with reference to the direction of gravity. The horizontal freezer 100 is generally placed on a level surface with its opening facing upwards. Defrosting water in the evaporator compartment 12 flows downwards along the direction of gravity through the drain pipe 30 until it flows into the water receiving section 23 in the compressor compartment 20. The water receiving section 23 collects the water discharged from the drain pipe 30.

[0039] Figure 2 , 3 In the middle, one end of the drain pipe 30 is connected to the drain outlet 13 by a thread, and the other end extends to the compressor chamber 20 to introduce water into the water receiving part 23.

[0040] During the operation of the freezer 100, the defrosting water generated in the evaporator compartment 12 needs to be discharged through the drainage system. Leaks at any connection point may cause water to seep into the compressor compartment 20 or other areas, affecting the safety and reliability of the equipment.

[0041] The threaded connection, through the tight screwing of the drain pipe 30 and the drain outlet 13, forms a high-strength sealing interface, which can effectively fill tiny gaps and ensure that the water flows only along the predetermined path, avoiding the risk of leakage.

[0042] Furthermore, threaded connections require no complex tools; the installation and removal of the drain pipe 30 and drain outlet 13 can be completed manually or with a simple screwdriver. Compared to permanent connection methods such as welding or bonding, threaded connections significantly reduce the difficulty and time cost of production and assembly.

[0043] When maintaining the freezer 100 or replacing the drain pipe 30, operators can quickly disassemble and reinstall it, facilitating the cleaning of limescale or the repair of damaged parts. This convenience improves the maintainability of the freezer 100 and extends its service life.

[0044] Furthermore, the threaded connection provides high connection strength through mechanical interlocking, making the drain pipe 30 less prone to loosening or falling off during long-term use. During the operation of the freezer 100, it may be affected by vibration or temperature changes; traditional plug-in or snap-fit ​​connections may fail due to fatigue. However, the helical structure of the threaded connection can withstand a certain degree of external stress, ensuring the stability of the drainage system under various operating conditions.

[0045] Furthermore, as will be explained below, the combination of the threaded connection with the first mating part 132 and the second mating part 311 can accurately control the rotation angle and position of the drain pipe 30 during installation, ensuring precise alignment of the pipe direction. This not only facilitates adaptation to the internal layout of different freezer models 100, but also optimizes the guidance of water flow and improves drainage efficiency.

[0046] The threaded connection structure of this embodiment achieves improvements in several aspects, including sealing performance, ease of installation, structural stability, adjustment flexibility, compatibility with horizontal layout, and economy, significantly enhancing the reliability and practicality of the freezer 100.

[0047] like Figure 1 , 3 As shown, the step portion 11 includes a step bottom wall 111 and a step side wall 112. The step bottom wall 111 is a horizontal structure, and the step side wall 112 extends upward perpendicular to the step bottom wall 111 to form a step shape.

[0048] The compressor chamber 20 includes a top wall 21 and a side wall 22. The top wall 21 is located below the bottom wall 111 of the step. The side wall 112 of the step is facing the side wall 22 of the chamber. The drain outlet 13 is connected to the side wall 112 of the step, and the drain pipe 30 passes through the side wall 22 of the chamber.

[0049] A certain distance is maintained between the step sidewall 112 and the nacelle sidewall 22. This distance can be filled with foam material to prevent the step sidewall 112 from directly contacting the nacelle sidewall 22.

[0050] The drain pipe 30 starts from the drain outlet 13, passes through the side wall 22 of the evaporator compartment, and finally enters the compressor compartment 20. This arrangement ensures a compact layout of the evaporator compartment 12 and the compressor compartment 20 in the horizontal direction, reducing the space occupied in the height direction of the freezer 100.

[0051] Furthermore, such as Figure 4 , 5 As shown in Figures 6 and 7, the drain pipe 30 includes a first drain pipe 31, a drain pipe connector 32, and a second drain pipe 33, which are connected in sequence to form a complete drainage path.

[0052] The first drain pipe 31 is located between the side wall 112 of the step and the side wall 22 of the machine room, and one end of it is connected to the drain outlet 13 by a thread.

[0053] An opening 222 is provided on the side wall 22 of the cabin. The drain pipe connector 32 passes through the opening 222 to connect the first drain pipe 31 and the second drain pipe 33.

[0054] The second drain pipe 33 is located inside the compressor chamber 20, and its end extends above the water receiving part 23 to drain water into the water receiving part 23.

[0055] The first drain pipe 31 and the drain pipe connector 32 are connected by threads to ensure the sealing and stability of the connection.

[0056] The second drain pipe 33 is connected to the drain pipe connector 32 by a snap-fit ​​mechanism, facilitating installation and disassembly. This segmented design improves the flexibility and ease of maintenance of the drainage system.

[0057] like Figure 5 , 9 As shown, the evaporator compartment 12 is equipped with a water receiving base plate 121 for collecting defrosting water generated by the evaporator.

[0058] The water receiving plate 121 is tilted downwards at an angle of 3° to 15° to ensure that the water flows to the bottom.

[0059] The drain outlet 13 is located at the lowest point of the water receiving base plate 121, and its interior is provided with a downward-sloping drain channel 135, with the inclination angle being consistent with that of the water receiving base plate 121.

[0060] The drain outlet 13 includes a first outlet 134 and a second outlet 136. The first outlet 134 is located above the second outlet 136 and is connected to the bottom of the water receiving base plate 121.

[0061] The second outlet 136 is located outside the drain outlet 13 and is connected to the first drain pipe 31 by a thread.

[0062] The bottom of the first outlet 134 is provided with a water-receiving edge 1341, such as Figure 9 As shown, the water receiving edge 1341 extends a predetermined length (e.g., 5-30 mm) along the bottom of the water receiving base plate 121. The water receiving edge 1341 is aligned with the bottom of the water receiving base plate 121 along the predetermined length to ensure that the water flows smoothly to the drainage channel 135 and avoids leakage.

[0063] Compared to the traditional circular drain hole design, which has a point contact, this embodiment designs the first outlet 134 as an irregularly shaped hole with a certain length for the water receiving edge 1341, ensuring that more defrosting water flows smoothly into the drain channel 135.

[0064] like Figure 6 and 7 As shown, the second outlet 136 is provided with a first docking part 132, such as Figure 6 and 8 As shown, the first drain pipe 31 is provided with a second connecting part 311.

[0065] The first docking part 132 is a groove structure and is located on the inner wall of the second outlet 136. The outer wall of the first drain pipe 31 has a protrusion as the second docking part 311.

[0066] During the threaded connection between the first drain pipe 31 and the second outlet 136, when rotated to the predetermined position, the protrusion engages with the groove, achieving a locking action. This design ensures that the drain pipe 30 is fixed in direction after installation, preventing loosening or displacement.

[0067] like Figure 6 and 7 As shown, the second outlet 136 also includes a first covering part 133, which is an annular structure with its edge folded towards the first drain pipe 31.

[0068] like Figure 6 and 8 As shown, the first drain pipe 31 is provided with a second covering part 312, and the edge is folded towards the first covering part 133.

[0069] like Figure 6 As shown, after the threaded connection is completed, the folded edges of the first covering part 133 and the second covering part 312 fit tightly together, forming a multi-layer sealing interface to prevent defrost water leakage. Even if the threaded connection develops tiny gaps due to vibration or temperature changes, the covering structure fills the gaps and maintains the seal. At the same time, the annular design of the covering part disperses stress and prevents seal failure.

[0070] Furthermore, the annular structure of the covering disperses the stress at the connection, ensuring uniform pressure distribution at the edges and reducing the risk of seal failure caused by local stress concentration.

[0071] In addition, the folded design of the covered part increases the contact area and friction, making the connection less prone to loosening and extending the seal life. Especially during the operation of the freezer 100, defrosting water may contain trace impurities or corrosive components, and the covered structure further prevents these substances from corroding the threaded connection.

[0072] Furthermore, a first internal thread 131 is provided in the second outlet 136, and a second internal thread is provided in the drain pipe connector 32.

[0073] The first drain pipe 31 has external threads at both ends. One end is screwed into the first internal thread 131 and connected to the second outlet 136; the other end is screwed into the second internal thread and connected to the drain pipe connector 32.

[0074] This threaded connection design ensures a tight fit between the first drain pipe 31 and the drain outlet 13, and has high tensile strength and vibration resistance.

[0075] Combining threaded connections and an encasing design, the connection between the first drain pipe 31 and the drain outlet 13 not only provides mechanical stability but also achieves excellent sealing performance. The engagement of the first mating part 132 (groove) and the second mating part 311 (protrusion) further assists in positioning, ensuring that the first encasing part 133 and the second encasing part 312 are precisely fitted in the predetermined positions. This multi-layer sealing mechanism effectively prevents water accumulation in the compressor compartment 20 or equipment failure due to leakage during long-term operation of the freezer 100, thereby improving the reliability and service life of the freezer 100.

[0076] Therefore, the design of the threaded connection combined with the covering part solves the problem of loose connections or water leakage in the traditional refrigeration cabinet 100 drainage system. Especially in the scenario where the evaporator compartment 12 and the compressor compartment 20 are arranged horizontally, the requirements for the sealing and stability of the connection for lateral drainage are higher. The covering structure significantly improves the connection and sealing performance of the drain pipe 30, meeting the high-efficiency and stable use requirements of the refrigeration cabinet 100.

[0077] Continue as Figure 6 As shown, the second drain pipe 33 is connected to the drain pipe connector 32 via a snap-fit ​​structure. The snap-fit ​​joint is equipped with an elastic buckle to ensure a secure connection. This design, combining threaded connections and snap-fit ​​joints, balances installation efficiency and structural strength.

[0078] The first drain pipe 31 has an inclination angle of 3° to 15°, and the second drain pipe 33 has an inclination angle of 3° to 20°. This inclination design utilizes gravity to ensure that defrosting water flows naturally to the water inlet 23, preventing water accumulation in the pipes. At the same time, the inner wall of the drain pipe 30 is smoothed to reduce scale buildup and further improve drainage efficiency.

[0079] like Figure 2 , 6 As shown, the drain pipe connector 32 includes a pressure plate 321, which is an annular structure with a diameter slightly larger than the opening 222 on the side wall 22 of the nacelle.

[0080] The side wall 22 of the cabin is provided with an inclined plate 221, which surrounds an opening 222 with an inclination angle of 3° to 30°.

[0081] After the drain pipe connector 32 passes through the opening 222, the pressure plate 321 is located on the side of the inclined plate 221 near the press chamber 20 and is in contact with the surface of the inclined plate 221.

[0082] The pressure plate 321 is fixed to the inclined plate 221 by bolts or adhesive, covering the gap between the drain pipe connector 32 and the opening 222. On the one hand, it prevents the foaming material from overflowing into the press chamber 20 during foaming; on the other hand, it prevents moisture or dust from entering the press chamber 20. This design enhances the sealing and reliability of the drainage system.

[0083] Other examples Figure 8 As shown, the main body of the first drain pipe 31 is a cylindrical pipe with two bends. Generally, the drain outlet 13 is in the middle position in the front-to-back direction, while the water receiving part 23 is not necessarily in the middle. Therefore, the first drain pipe 31 guides the water to different positions. The connecting pipes with different distances between the two bends guide the water to different positions.

[0084] The bending angle of the curved section can be from 30° to 150°, allowing it to extend horizontally from the drain outlet 13 of the evaporator compartment 12 to the opening 222 on the side wall 22 of the compartment. This bending design effectively adapts to the space between the horizontally arranged evaporator compartment 12 and the compressor compartment 20, optimizing the internal layout of the freezer 100.

[0085] In addition, the first drain pipe 31 is placed at a downward angle, with an inclination angle of 3° to 15° (the specific angle can be optimized according to the size of the freezer 100 and water flow requirements). The inclined design utilizes gravity to ensure smooth flow of defrosting water and reduce the risk of water accumulation in the pipe. The inner wall of the pipe is polished, with a low surface roughness, further reducing water flow resistance.

[0086] Compared with the prior art, this embodiment has the following beneficial effects:

[0087] The freezer 100 improves space utilization efficiency by horizontally arranging the evaporator compartment 12 and the compressor compartment 20. The drain pipe 30 and drain outlet 13 are connected by threads to ensure sealing and stability, effectively preventing leakage. The drain pipe 30 introduces water into the water receiving part 23 within the compressor compartment 20, achieving efficient drainage. This invention optimizes the structure of the freezer 100, improves the reliability and convenience of the drainage system, and has significant innovative advantages.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
