Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a freezer. Background Technology

[0002] In existing horizontal freezers, the drain pipe is typically fixed to the inner liner during assembly and then installed into the outer shell from top to bottom along with the inner liner. The drain pipe is then inserted into the compressor compartment by the lateral movement of the inner liner to drain the defrost water from the evaporator. Due to limited operating space and blind assembly, this method is prone to the following problems:

[0003] Under blind assembly conditions, when assembling the inner liner and the outer shell, it is difficult to accurately align the drain pipe with the receiving component of the press chamber, which may result in a failure to connect smoothly.

[0004] Due to blind installation, the drain pipe is prone to collision, scratching, or being pressed against the machine compartment partition in the compressor chamber during the installation process, which may cause damage to the pipe or poor connection, affecting the overall drainage function of the freezer.

[0005] Therefore, in the process of refrigerated cabinet assembly, how to ensure the reliable connection between the first drain pipe and the internal components of the compressor compartment under blind assembly conditions, while avoiding collisions and damage caused by lateral movement, has always been a technical problem that urgently needs to be solved. Utility Model Content

[0006] To address the difficulties in assembly and the risk of mechanical collision during the assembly of existing freezers, the purpose of this invention is to provide a freezer that simplifies the assembly process, avoids mechanical collisions and damage, and improves product reliability. 。

[0007] To achieve the above-mentioned utility model objectives, one embodiment of this utility model provides a freezer, comprising:

[0008] Box shell;

[0009] The inner liner has a stepped portion, and a stepped space is formed on the outer side of the stepped portion;

[0010] A press chamber, which is housed in the stepped space, the press chamber including a cabin partition;

[0011] The first drain pipe is pre-installed in the inner liner. After the inner liner is assembled with the shell, there is a preset distance between the end of the first drain pipe near the cabin bulkhead and the cabin bulkhead. The preset distance ensures that the first drain pipe does not contact the cabin bulkhead during the process of the inner liner being installed into the shell.

[0012] As a further improvement of this utility model, through holes are provided on the engine compartment partition, and a press space is formed inside the press chamber;

[0013] The freezer also includes a drain pipe connector, which passes through the through hole from inside the compressor space and is connected to the first drain pipe. The drain pipe connector includes a baffle that closes the through hole on the side of the through hole closest to the compressor space.

[0014] As a further improvement of this utility model, the freezer also includes a second drain pipe and a water receiving tray. The second drain pipe is disposed in the compressor chamber. One end of the second drain pipe is connected to the drain pipe connector, and the other end is used to introduce water into the water receiving tray.

[0015] As a further improvement of this utility model, the second drain pipe is snapped into place with the drain pipe connector.

[0016] As a further improvement of this utility model, the water receiving tray is disposed below the second drain pipe, and the first drain pipe, the drain pipe connector and the second drain pipe are all inclined downward.

[0017] As a further improvement of this utility model, the cabin partition includes a supporting wall, the baffle abuts against the supporting wall, and the planes where the baffle and the supporting wall are located are both perpendicular to the direction of inclination of the drain pipe connector.

[0018] As a further improvement of this utility model, the end face of the first drain pipe near the side of the cabin bulkhead is parallel to the plane where the supporting wall is located.

[0019] As a further improvement of this utility model, the drain pipe connector is threadedly connected to the first drain pipe.

[0020] As a further improvement of this utility model, the distance from one end of the drain pipe connector that passes through the through hole to the cabin bulkhead is greater than the preset distance;

[0021] During the tightening process of the drain pipe connector, the baffle abuts against the cabin bulkhead.

[0022] As a further improvement of this utility model, through holes are provided on the engine compartment partition, and a press space is formed inside the press chamber;

[0023] The first drain pipe includes a telescopic part, which includes an elastic corrugated pipe or a telescopic sleeve structure. After the inner liner is installed into the box shell, the telescopic part extends and passes through the through hole into the press space.

[0024] Compared with existing technologies, this utility model has the following advantages: By pre-installing a first drain pipe in the inner liner and ensuring a preset distance between the end of the first drain pipe near the cabin bulkhead and the bulkhead after the inner liner is assembled with the shell, the inner liner can be directly inserted into the shell from top to bottom without additional lateral movement. This avoids the complexity of docking required in traditional blind assembly, making the assembly process simpler and faster. The preset distance ensures that the first drain pipe will never contact the cabin bulkhead during the entire process of inserting the inner liner into the shell, effectively preventing damage or wear to the pipe caused by collisions or scratches during assembly, thus improving the overall assembly quality and stability. In addition, by ensuring a reasonable distance between the first drain pipe and the cabin bulkhead, it is possible to ensure the correct connection of subsequent drain pipe connectors, forming a complete drainage path, thereby achieving efficient and stable drainage and improving the overall performance and reliability of the freezer. Therefore, this freezer not only overcomes the difficulties in docking and the vulnerability of the first drain pipe caused by blind assembly in existing technologies, but also significantly simplifies the assembly process, demonstrating significant technical advantages and economic benefits.

Detailed Implementation

[0034] 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.

[0035] 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.

[0036] One embodiment of this utility model provides a freezer that simplifies the assembly process, avoids mechanical collisions and damage, and improves product reliability.

[0037] A freezer 100 according to this embodiment includes a shell 20, an inner liner 10, a compressor compartment 30, and a first drain pipe 40.

[0038] like Figure 1 , 2 As shown in Figure 4, the inner liner 10 is provided with a stepped portion 11, and a stepped space 110 is formed on its outer side. The press chamber 30 is placed in the stepped space 110, and a machine compartment partition 31 is provided in the press chamber 30.

[0039] like Figures 2-5 As shown, before the inner liner 10 is installed with the outer shell 20, the first drain pipe 40 is pre-installed on the outlet of the inner liner 10. When the inner liner 10 and the outer shell 20 are assembled, the first drain pipe 40 is inserted into the outer shell 20 together with the inner liner 10.

[0040] The outer shell 20 is the outer shell of the freezer 100, usually made of metal or high-strength plastic, with sufficient structural strength to support the overall frame of the freezer 100. The inner liner 10 is installed inside the outer shell 20 as a space for storing frozen or refrigerated items, and its material can be low-temperature resistant plastic or metal composite material.

[0041] A stepped space 110 is formed on the outer side of the stepped section 11. The compressor compartment 30 is housed within the stepped space 110, and a compressor space 301 is formed inside it for installing refrigeration equipment such as compressors. The compressor compartment 30 includes a nacelle partition 31 with through holes 311 for connecting subsequent drain pipes. The nacelle partition 31 is made of metal or rigid plastic to ensure structural stability.

[0042] To clearly express the position and direction described in this embodiment, up and down are defined with reference to the direction of gravity. The freezer 100 in this embodiment can be a horizontal freezer 100, which is generally placed on a horizontal surface, with the opening of the storage space inside the inner liner 10 facing upwards. The freezer 100 is basically a cuboid structure, with the left and right sides along the length direction and the front and back sides along the width direction.

[0043] like Figure 5 As shown, one end of the first drain pipe 40 is close to the cabin bulkhead 31 and maintains a certain preset distance L1 from it; the preset distance L1 ensures that the first drain pipe 40 will never come into contact with the cabin bulkhead 31 during the process of the inner liner 10 being installed into the box shell 20 from top to bottom.

[0044] The inner liner 10 is pre-installed with a first drain pipe 40 for draining defrost water produced by the evaporator. The first drain pipe 40 can be made of corrosion-resistant PVC pipe or rubber pipe.

[0045] For freezers 100 of different sizes and specifications, the preset distance L1 may vary, and there may be some protrusions on the machine compartment partition 31 of some compressor compartments 30. In order to avoid these protrusions, a longer preset distance L1 can be set.

[0046] In the existing technology, on the one hand, the drain pipe needs to be moved laterally to connect with the press chamber 30, and the length of the drain pipe is longer than the distance between the inner liner 10 and the press chamber 30; on the other hand, the blind installation is difficult because the operation is not visible, which makes it easy for the inner liner 10 to fail to connect with the shell 20 or for the drain pipe to collide or scratch with the press chamber 30.

[0047] In this embodiment, the preset distance L1 of the refrigerator 100 in the blind installation state prevents the drain pipe from rubbing or colliding with the cabin bulkhead 31 due to lateral movement, ensuring the integrity of the drain pipe and the reliable connection of the subsequent drainage system, while simplifying the assembly process.

[0048] The following two examples will provide further details.

[0049] Example 1

[0050] In this embodiment, the freezer 100 also includes a drain pipe connector 50, which passes through the through hole 311 from inside the compressor space 301 and is connected to the first drain pipe 40.

[0051] The drain pipe connector 50 includes a baffle 51, which closes the through hole 311 on the side near the press space 301. When the foam insulation layer is filled during the manufacturing process of the freezer 100, the baffle 51 can prevent the foam material from entering the press chamber 30 through the through hole 311.

[0052] like Figure 2-7 As shown, the drain pipe connector 50 ensures effective communication between the first drain pipe 40 and the inside of the press chamber 30; secondly, after the baffle 51 closes the through hole 311, it can prevent the foaming material from entering the press chamber 30 during the production process, thereby protecting the equipment inside the press chamber 30 from external interference and improving the durability of the freezer 100.

[0053] Furthermore, the freezer 100 also includes a second drain pipe 60 and a drip tray 70.

[0054] The second drain pipe 60 is located inside the compressor chamber 30, with one end connected to the drain pipe connector 50 and the other end extending toward the water receiving tray 70 installed at the bottom.

[0055] The defrosting water flowing out of the inner liner 10 flows smoothly into the second drain pipe 60 through the first drain pipe 40 and the drain pipe connector 50, and finally collects in the water receiving tray 70.

[0056] The second drain pipe 60 and the drip tray 70 can effectively prevent water stagnation and backflow, ensure that water is discharged quickly, reduce the risk of freezing caused by defrosting water stagnation, and also help maintain the long-term stability of the entire drainage system and the safety of the freezer 100.

[0057] Furthermore, such as Figure 5 and 7 As shown, the second drain pipe 60 is snapped into place with the drain pipe connector 50.

[0058] The snap-fit ​​connection simplifies the installation and disassembly of the second drain pipe 60, making routine maintenance or replacement more convenient.

[0059] The snap-fit ​​structure has the advantages of easy assembly, strong connection, vibration resistance and impact resistance, which makes it possible to achieve a stable connection without the need for additional fasteners during assembly. At the same time, the snap-fit ​​connection method simplifies the installation and disassembly process of the second drain pipe 60, making daily maintenance or replacement more convenient.

[0060] The water receiving tray 70 is located below the second drain pipe 60 to ensure that defrosting water can flow naturally into the water receiving tray 70, avoiding water stagnation or backflow.

[0061] Meanwhile, the first drain pipe 40, the drain pipe connector 50, and the second drain pipe 60 are all designed with a downward sloping structure, with the sloping angle usually controlled between 3 and 10 degrees to facilitate the natural flow of water.

[0062] This layout improves the efficiency and stability of the drainage system, reduces the risk of water stains, and keeps the interior of the freezer clean and dry.

[0063] Furthermore, such as Figure 3 , 5 As shown in Figure 7, the cabin bulkhead 31 includes a retaining wall 312, and the baffle 51 abuts against the retaining wall 312 to form a stable support structure, which enhances the stability of the structure and makes the drain pipe connector 50 less likely to loosen or shift during long-term use.

[0064] The planes where the baffle 51 and the supporting wall 312 are located are perpendicular to the direction of inclination of the drain pipe connector 50, ensuring uniform force distribution. This allows the baffle 51 to firmly abut against the supporting wall 312 when the connector is tightened, so that the first drain pipe 40 can accurately approach the cabin bulkhead 31 after being pulled, forming a uniform sealing contact. This effectively prevents loose connections and water leakage caused by poor sealing, while also preventing the seepage of foaming material, ensuring the stability and sealing performance of the freezer 100 during long-term use.

[0065] like Figure 5 As shown, the end face of the first drain pipe 40 near the cabin bulkhead 31 is parallel to the plane where the abutment wall 312 is located.

[0066] This ensures that the first drain pipe 40 maintains a stable relative position with the cabin bulkhead 31 and the supporting wall 312, thereby avoiding poor connection caused by relative movement or offset during the entire assembly and subsequent use.

[0067] The parallel structure allows the first drain pipe 40 to be precisely connected to the drain pipe connector 50 when the inner liner 10 is installed into the shell 20, forming a good drainage channel and further improving the sealing and reliability of the drainage system.

[0068] like Figure 5 and 7 The drain pipe connector 50 shown is threadedly connected to the first drain pipe 40.

[0069] During the assembly process, the first drain pipe 40 pre-installed on the inner liner 10 is provided with an external or internal thread structure, and the corresponding part of the drain pipe connector 50 is provided with a matching thread.

[0070] Figure 5 and 7In the middle, the drain pipe connector 50 is provided with internal thread, and the first drain pipe 40 is provided with external thread, and the two are screwed together.

[0071] The threaded connection allows for precise adjustment of the two components during connection and achieves a tight fit by tightening. A uniform and reliable sealing interface is formed between the first drain pipe 40 and the drain pipe connector 50, thereby preventing water leakage at the interface.

[0072] In addition, the threaded structure has excellent vibration resistance, ensuring that loosening of the connection caused by vibration or temperature changes during the operation of the freezer 100 is effectively avoided. This connection method also facilitates future disassembly or maintenance, enabling quick tightening and loosening, improving assembly efficiency and maintenance convenience.

[0073] Furthermore, the distance from one end of the drain pipe connector 50 passing through the through hole 311 to the cabin bulkhead 31 is greater than the preset distance L1; during the tightening process of the drain pipe connector 50, the baffle 51 abuts against the cabin bulkhead 31.

[0074] When the drain pipe connector 50 passes through the through hole 311, its protruding part must be left with sufficient length to ensure that when the connector is tightened, the first drain pipe 40 can be pulled toward the cabin bulkhead 31 so that the baffle 51 is in close contact with the bulkhead.

[0075] When the first drain pipe 40 is tightened with threaded connection, it is automatically pulled toward the cabin bulkhead 31 to achieve tight fit and precise positioning, which enhances the sealing effect and effectively eliminates gaps that may be caused by assembly tolerances or small displacements, preventing foam material from seeping in during assembly or foaming.

[0076] Example 2

[0077] The difference between this embodiment and embodiment 1 is that in embodiment 1, the drain pipe connector 50 extends between the press chamber 30 and the inner liner 10 and connects with the first drain pipe 40, while in this embodiment, the first drain pipe 40 includes a telescopic part, which includes an elastic corrugated pipe or a telescopic sleeve structure. After the inner liner 10 is installed into the box shell 20, the telescopic part extends and passes through the through hole 311 into the press space 301.

[0078] When the inner liner 10 is inserted into the housing 20, the telescopic part, which was originally in a compressed state, automatically extends and passes through the through hole 311 on the engine compartment partition 31 into the interior of the compressor chamber 30.

[0079] More specifically, before assembly, the first drain pipe 40 is pre-assembled on the inner liner 10, but the design has a retractable structural part, so that it can automatically compensate according to the actual distance after assembly, ensuring a reliable connection with the drain pipe connector 50.

[0080] After the telescopic part is installed in the inner liner 10 into the shell 20, the worker pulls the telescopic part outward from the through hole 311 of the press chamber 30, extending it into the press chamber 30.

[0081] This structure ensures that the first drain pipe 40 can extend into the compressor chamber 30.

[0082] Alternatively, the gap between the expansion joint and the through hole 311 can be filled to prevent the foaming material from entering the press chamber 30.

[0083] Compared with commonly used technologies, this embodiment has the following advantages:

[0084] By pre-installing the first drain pipe 40 in the inner liner 10 and ensuring a preset distance L1 between the end of the first drain pipe 40 near the cabin partition 31 and the cabin partition 31 after the inner liner 10 is assembled with the cabinet 20, the inner liner 10 can be directly inserted into the cabinet 20 from top to bottom without additional lateral movement. This avoids the complexity of docking required in traditional blind assembly, making the assembly process simpler and faster. The preset distance L1 ensures that the first drain pipe 40 will never contact the cabin partition 31 during the entire process of the inner liner 10 being installed into the cabinet 20, effectively preventing damage or wear to the pipe caused by collisions or scratches during assembly, and improving the overall assembly quality and stability of the machine. In addition, by ensuring a reasonable distance between the first drain pipe 40 and the cabin partition 31, it is possible to ensure the correct connection of the subsequent drain pipe connector 50, forming a complete drainage path, thereby achieving efficient and stable drainage and improving the overall performance and reliability of the refrigerator 100. Therefore, the freezer 100 not only overcomes the difficulties in connecting the first drain pipe 40 and the problem of easy damage caused by blind assembly in the existing technology, but also greatly simplifies the assembly process, and has obvious technical advantages and economic benefits.

[0085] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. 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.

[0086] The detailed descriptions listed above are merely specific descriptions of feasible implementation methods of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementation methods or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
