Description

Technical Field

[0001] This application relates to the field of commercial refrigeration equipment technology, and in particular to a defrosting water guide structure for a salad bar refrigeration unit. Background Technology

[0002] Commercial refrigeration equipment (such as salad bar) is the core equipment for storing fresh ingredients in the catering industry. It needs to meet requirements such as low-temperature preservation, convenient operation, and hygiene and safety. Traditional salad bar refrigeration equipment is scattered, and installation and maintenance are complicated. The core components of the salad bar, such as the compressor, condenser, and evaporator, are mostly independently and separately designed. During maintenance, each component needs to be disassembled one by one, which is difficult to operate. At the same time, the defrosting water of traditional equipment is mostly discharged directly through the drain hole inside the cabinet. If not handled properly, it can easily remain at the bottom of the cabinet, breed bacteria or contaminate food, and increase food safety risks. Utility Model Content

[0003] To improve the problems of refrigeration component dispersion and food contamination, this application provides a defrosting water guiding structure for a salad bar refrigeration unit.

[0004] The defrosting water guiding structure of the salad bar refrigeration unit provided in this application adopts the following technical solution: A defrosting water guiding structure for a salad bar refrigeration unit includes a supporting shell and an evaporator and a compressor bolted to the supporting shell. The evaporator is provided with a water receiving tray, and the water receiving tray is provided with a guide pipe assembly for guiding water flow. An evaporation dish connected to the guide pipe assembly is provided outside the guide pipe assembly. The supporting shell is provided with a food storage chamber and a drainage chamber. The evaporator, water receiving tray, guide pipe assembly, evaporation dish, and compressor are modularly integrated inside the drainage chamber and separated from the food storage chamber.

[0005] By adopting the above technical solution, the supporting shell, evaporator and compressor are set by bolts, and the evaporator, water tray, guide pipe assembly, evaporation dish and compressor are modularly integrated into the drainage chamber. Through modular integration and partition design, the generation and discharge system of defrost water is completely isolated from the food storage chamber, fundamentally eliminating cross-contamination and greatly simplifying the installation and maintenance process of the unit.

[0006] Preferably, the water receiving tray has a V-shaped cross-section.

[0007] By adopting the above technical solution, the inclined structure is used to accelerate the collection of defrosting water and guide it to the diversion pipe assembly, avoiding water accumulation and ensuring drainage efficiency.

[0008] Preferably, the guide pipe assembly includes at least two interconnected guide short pipes, the guide short pipes are fixedly disposed with a water receiving tray, a first clamping plate is fixedly disposed on the guide short pipe, a first clamping ring is disposed inside the first clamping plate and fixedly connected to the guide short pipe, a second clamping plate is fixedly disposed at the end of the guide short pipe away from the first clamping plate, a second clamping ring is disposed inside the second clamping plate and fixedly connected to the guide short pipe, the first clamping plate, the first clamping ring, the second clamping plate and the second clamping ring are all arranged in a circular array around the central axis of the guide short pipe, and the first clamping plate and the second clamping plate are both rotated and locked by a limiting structure.

[0009] By adopting the above technical solution, the diversion tube assembly is composed of multiple diversion short tubes spliced ​​together by clamp plate one, clamp plate two, clamp ring one, clamp ring two and limiting structure. Its core function is to form a modular diversion channel that can be quickly disassembled and is easy to clean. At the same time, mechanical interlocking ensures the sealing and stability of the connection.

[0010] Preferably, the limiting structure includes a limiting plate fixedly disposed with one of the card plates, a limiting groove is provided on the limiting plate, a sliding groove is provided on one of the card plates, a card block is slidably disposed in the sliding groove, a return spring is fixedly disposed between the card block and the sliding groove, and sealing rings are fixedly disposed at both ends of the guide tube.

[0011] By adopting the above technical solution, the limiting structure achieves a quick connection between the guide tubes through the cooperation of the limiting plate, the locking block and the return spring, and automatically locks with the slot through the spring pressure to prevent loosening during use. At the same time, the sealing rings on both sides ensure the sealing of the connection.

[0012] Preferably, one of the flow guide tubes is provided with a filter bag, and the filter bag is provided with a magnetic suction ring that is fixedly connected to the flow guide tube.

[0013] By adopting the above technical solution, the filter bag can be conveniently installed at the pipe inlet by the magnetic force of the magnetic ring to filter solid impurities in the defrosting water, prevent clogging of downstream pipes and evaporating dishes, and is easy to remove and clean.

[0014] Preferably, the end of the retaining ring one opposite to that of the retaining ring two is inclined.

[0015] By adopting the above technical solution, one end of the retaining ring is inclined, which serves to guide and secure the connection during docking.

[0016] Preferably, the card block is provided with an inclined surface that slides against the limiting plate.

[0017] By adopting the above technical solution, the inclined surface set on the card block generates a component force to compress the spring when it comes into contact with the limiting plate, realizing tool-free automatic locking and simplifying the connection operation.

[0018] Preferably, the end of the locking block furthest from the reset spring is L-shaped.

[0019] By adopting the above technical solution, the L-shaped design allows staff to easily move the card blocks.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. By modularly integrating the evaporator, water tray, drain pipe assembly, evaporating dish, and compressor and bolting them into the drain chamber, and connecting them to the cabinet via a waterproof quick-connect plug, when the unit needs maintenance, there is no need to operate on the scattered components in the confined cabinet. Maintenance personnel only need to disconnect the quick-connect plug and unscrew the screws to remove the entire faulty module and replace it with a new pre-installed module, reducing the complexity and technical requirements of on-site installation.

[0021] 2. By designing an independent drainage chamber on the outside of the cabinet, the food storage chamber is separated from the drainage chamber. The evaporator, drip tray, guide pipe assembly, evaporation dish and compressor are all installed inside the drainage chamber. By placing the entire process of defrosting water generation, diversion and evaporation outside the food storage chamber, physical isolation is achieved, avoiding the risk of defrosting water and the bacteria and mold it carries contaminating ready-to-eat ingredients such as salads and fruits.

[0022] 3. The defrost water is sealed and directionally transported by a series of short guide tubes. These short guide tubes are fully detachable, allowing users to easily clean the inside of the pipes. The combination of multiple short guide tubes allows for flexible adjustment of the guide tube length according to the specific internal structure of different salad bar models. The guide tubes are locked during installation by rotating them together. The cooperation of clamping plates one and two with the limiting groove, as well as the pre-tightening force provided by the return spring, ensures that the connection point will not loosen or leak under vibration and long-term use, resulting in high reliability.

[0025] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0026] This application discloses a defrosting water guide structure for a salad bar refrigeration unit.

[0027] Example 1 Reference Figures 1 to 4 A defrosting water guiding structure for a salad bar refrigeration unit includes a supporting shell 1 and an evaporator 2 and a compressor 6 bolted to the supporting shell 1. The mounting end of the evaporator 2 is fixed to the inner vertical surface of the supporting shell 1, and the mounting end of the compressor 6 is fixed to the inner bottom surface of the supporting shell 1. The bottom end of the evaporator 2 is fixed to a water tray 3. A guide pipe assembly 4 is provided inside the water tray 3 to guide the water flow. An evaporating dish 5 is provided at the bottom end of the guide pipe assembly 4. The bottom surface of the evaporating dish 5 is fixed to the inner bottom of the supporting shell 1, and the bottom end of the guide pipe assembly 4 faces the inside of the evaporating dish 5. A food storage chamber 11 and a drain chamber 12 are provided inside the supporting shell 1. The evaporator 2, water tray 3, guide pipe assembly 4, evaporating dish 5, and compressor 6 are modularly integrated inside the drain chamber 12 and separated from the food storage chamber 11. They are connected to the cabinet through a waterproof quick plug. The cross-section of the water tray 3 is V-shaped.

[0028] When the evaporator 2 is in use, the frost melts into water, which drips into the V-shaped water collection tray 3 below it. The V-shaped design guides the water flow to quickly converge at the lower center. The collected defrosting water flows into the inlet of the guide pipe assembly 4 connected to the water collection tray 3. Under the action of gravity, the water flows through the guide pipe assembly 4 and is guided into the evaporating dish 5. The entire process takes place in the independent drain chamber 12, which is completely physically isolated from the food storage chamber 11 to ensure hygiene. The defrosting water flowing into the evaporating dish 5 is evaporated by electric heating. When the entire module needs maintenance, simply disconnect the electrical connection and loosen the fixing bolts to remove the entire module, which integrates the evaporator 2, water collection tray 3, guide pipe assembly 4, evaporating dish 5, and compressor 6, from the drain chamber 12 for quick replacement or repair.

[0029] Among them, the evaporator 2 and the compressor 6 are existing technologies, and their structural principles will not be described in detail. The entire system is connected through pre-installed electrical circuits and is controlled and started by the main controller of the equipment. When the controller starts the defrosting cycle, the heating element of the evaporator 2 works, and the melted frost water drips into the V-shaped evaporator 2, collects and flows into the evaporating dish 5 for evaporation.

[0030] The implementation principle of the defrosting water guiding structure of the salad bar refrigeration unit in this application embodiment is as follows: the defrosting water drips from the evaporator 2 to the V-shaped water receiving tray 3, and is then guided by gravity through the guide pipe assembly 4 to the evaporation dish 5, and finally evaporated by electric heating; the entire module is isolated from the food storage cavity 11 and can be quickly disassembled and maintained.

[0031] Example 2 Reference Figure 5 , Figure 6 The guide tube assembly 4 includes at least two interconnected guide tubes 41. The top guide tube 41 is fixed to the bottom of the V-shaped center of the water receiving tray 3, allowing water to flow into the guide tube 41. During installation, the shell of the evaporator 2 clamps the top guide tube 41. The outer wall of the top of the guide tube 41 is fixed to the bottom inner side of two clamping plates 42. The inner sides of the two clamping plates 42 are respectively fixed to the bottom of two retaining rings 43. The inner sides of the two retaining rings 43 are fixed to the outer wall of the top of the guide tube 41. The surface of the guide tube 41 is fixed to the top inner side of two clamping plates 46. Located at the end of the guide tube 41 away from the first clamping plate 42, the top inner sides of the two second clamping plates 46 are fixed to the top of the two second clamping rings 47, and the inner side of the second clamping rings 47 is fixed to the outer wall of the bottom end of the guide tube 41. The two first clamping plates 42, the two first clamping rings 43, the two second clamping plates 46, and the two second clamping rings 47 are all arranged in a circular array around the central axis of the guide tube 41. The first clamping plate 42 and the second clamping plate 46 are both rotated and locked by a limiting structure. The opposite end of the first clamping ring 43 and the second clamping ring 47 is inclined to ensure a tight connection during the rotation of the two guide tubes 41.

[0032] When connecting the guide tube 41, the guide tube 41 connected to the water receiving tray 3 needs to be installed in advance. Hold one guide tube 41 and bring one end of the guide tube 41 with the first clamping plate 42 and the first clamping ring 43 close to the second clamping plate 46 and the second clamping ring 47 at the bottom of the other guide tube 41. When the two guide tubes 41 overlap, rotate the connected guide tube 41 so that the first clamping ring 43 enters the inside of the second clamping plate 46 and the second clamping ring 47 enters the inside of the first clamping plate 42 and nests with each other. At this time, the two guide tubes 41 cannot move up or down to separate. During the rotation, the two guide tubes 41 are rotated and locked by the limiting structure to realize the installation of the two guide tubes 41. When disassembling, the staff can actively unlock the limiting structure and rotate the guide tube 41 in the opposite direction to disassemble it and clean the inside of the pipe. The guide tube 41 of the guide tube assembly 4 and the water receiving tray 3 are both made of food-grade polypropylene (PP) material and are integrally molded by injection molding.

[0033] Reference Figure 7 , Figure 8 The limiting structure includes a limiting plate 44 fixedly disposed with one of the first locking plates 42. The bottom of the limiting plate 44 is located above the first locking plate 42 and fixed to the upper surface of the first locking plate 42. A limiting groove 45 is formed on the lower surface of the limiting plate 44. A sliding groove 49 is formed on one of the second locking plates 46, which penetrates the interior of the second locking plate 46. The inner wall of the sliding groove 49 is slidably connected to the outer wall of the locking block 48 without gaps to avoid instability during sliding. The top and bottom surfaces of the locking block 48 are fixed to the top of the return spring 410. The bottom end of the guide tube 41 is fixed to the surface of the slide groove 49. Both ends of the guide tube 41 are fixed to the surface of the sealing ring 411. When the two guide tubes 41 are connected, the sealing ring 411 needs to be squeezed before installation. The top of the locking block 48 is provided with an inclined surface. The bottom end of the inclined surface is located in the slide groove 49, so that the limiting plate 44 directly contacts the inclined surface when it rotates. The inclined surface slides against the limiting plate 44. The end of the locking block 48 away from the return spring 410 is L-shaped, which makes it convenient for the staff to move the limiting plate 44. The sealing ring 411 is preferably made of food-grade EPDM rubber.

[0034] During the docking and rotation of the two guide tubes 41, when the inclined surface on the locking block 48 contacts the edge of the limiting plate 44, the inclined surface generates a component force, pressing the locking block 48 to slide inward and compressing the return spring 410. As the rotation continues until the locking block 48 aligns with the limiting groove 45 on the limiting plate 44, the compressed return spring 410 will immediately push the locking block 48 outward, so that the locking block 48 is firmly locked into the limiting groove 45, completing the automatic mechanical locking and effectively preventing the connection from loosening. When disassembly, cleaning, or replacement is required, simply move the L-shaped bottom end of the locking block 48 downward with your finger so that the top of the inclined surface of the locking block 48 completely exits the limiting groove 45, and then rotate the guide tube 41 in the opposite direction to easily separate the two guide tubes 41. The whole process is tool-free, simple, and quick.

[0035] Reference Figure 5 A filter bag 7 is installed on the guide pipe 41 connected to the water receiving tray 3. An iron ring is installed on the outer ring of the top of the filter bag 7. A magnetic ring 71 is attracted to the iron ring of the filter bag 7. The magnetic ring 71 is fixed to the inner side of the guide pipe 41.

[0036] At the top inlet of the guide tube 41, the filter bag 7 can be quickly and securely installed by the mutual attraction between the iron ring on the filter bag 7 and the magnetic ring 71. The defrosting water flowing out of the water receiving tray 3 first passes through this filter bag 7. Solid impurities such as dust and detached fins of the evaporator 2 that may be contained in the water are intercepted by the filter bag 7 to prevent clogging. When cleaning is required, simply pull the filter bag 7 upwards to separate it from the magnetic ring 71 and remove the filter bag 7. The filter bag 7 has a large filtration area, and impurities will be washed to the bottom by the water flow. The upper filtration port can still continue to filter. The filter bag 7 can be reused and is extremely easy to maintain.

[0037] The implementation principle of the defrosting water guide structure of the salad bar refrigeration unit in this application embodiment is as follows: The guide pipe assembly 4 achieves quick assembly and disassembly through its unique clamping plate 1 42, clamping plate 2 46 and limiting structure: During installation, the two guide pipe sections 41 are aligned, the pipe body is rotated, the clamping block 48 is compressed back and automatically springs into the limiting groove 45 under the action of the return spring 410, thus completing the locking. At the same time, the sealing ring 411 is compressed to ensure sealing; During disassembly, it is only necessary to move the bottom end of the clamping block 48 away from the limiting groove 45 and rotate it in the opposite direction to separate the guide pipe 41. The whole process does not require tools and is convenient and reliable.

[0038] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
