[0004] Secondly, the connection method between the existing base assembly of the display cabinet refrigeration system and the display cabinet box body is relatively fixed and lacks flexibility. When it is necessary to replace the display cabinet box body according to different display requirements or site conditions, it is often necessary to reinstall or adjust the entire base assembly of the refrigeration system, which is cumbersome to operate, increasing the use cost and time cost.

[0005] In addition, during the operation of the refrigeration system, condensate is generated. The existing condensate treatment methods are often not efficient enough, which may lead to the accumulation of condensate, affecting the normal operation of the refrigeration system and even causing failures. Summary of the Invention

Condensation not only affects the display effect of the items in the display cabinet, making it difficult for customers to clearly observe the goods, but also excessive condensation may drip onto the ground, causing the ground to be slippery, posing a safety hazard to customers, and at the same time increasing the workload of cleaning and maintenance.

[0007] To achieve the above object, the present invention provides a standard vertical display cabinet refrigeration system base assembly with a freely switchable cabinet, including a housing located at the bottom of the display cabinet. A compressor, a condenser, and an evaporation assembly are installed inside the housing. A lower front cover is installed on one side of the housing. The condenser sucks air on one side, dissipates heat on the other side, and cools the compressor through a condensation fan. The air flow blows directly on the lower front cover after passing through the compressor, and forms an air flow through the hot air outlet at the top of the lower front cover to blow on the upper display cabinet glass door, so that the condensation on the glass door evaporates through high temperature. The condensed water of the evaporation assembly is introduced into a water receiving box through an evaporator drain pipe, and an evaporation water heating pipe is installed at the inner bottom of the water receiving box.

[0008] As a preferred solution of the present invention, a water receiving groove is provided at the top of the lower front cover to prevent the condensation water droplets on the glass door from dripping, and the water outlet at one side of the water receiving groove is connected to the water receiving box through a pipeline.

[0014] As a preferred solution of the present invention, sealing sleeves are sleeved at the joints of the air inlets and air outlets with the display cabinet.

[0015] As a preferred solution of the present invention, the evaporation water heating pipe is heated by electricity, and the evaporation water heating pipes are distributed on the inner bottom wall of the water receiving box.

[0016] As a preferred solution of the present invention, the top side of the housing is clamped and matched with the outer side of the bottom of the display cabinet through a lock catch.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. In the standard vertical display cabinet refrigeration system base assembly with a freely switchable cabinet, the condenser cools the compressor through a condensing fan. The air flow blows directly on the front lower cover after passing through the compressor, and then forms an air flow through the hot air outlet at the top of the front lower cover and blows towards the display cabinet glass door. This design enables the condensation on the glass door to evaporate through high temperature, greatly reducing the occurrence of condensation on the glass door, ensuring a clear display effect of the items inside the display cabinet, enhancing the shopping experience of customers, and at the same time avoiding the condensation dripping onto the ground to cause the ground to be slippery, reducing potential safety hazards, and decreasing the workload of cleaning and maintenance.

[0018] 2. In the standard vertical display cabinet refrigeration system base assembly with a freely switchable cabinet, several positioning pins installed on the top of the outer shell cooperate with the positioning holes at the bottom of the display cabinet, and the side of the top of the outer shell is clamped and cooperated with the outer side of the bottom of the display cabinet through a lock. This dual connection method makes the connection between the display cabinet refrigeration system base assembly and the display cabinet body more flexible and reliable. When it is necessary to replace the display cabinet body according to different display requirements or site conditions, only simple positioning and clamping operations are required to complete the switching of the cabinet body, without the need to reinstall or adjust the entire refrigeration system base assembly. The operation is simple and fast, reducing the usage cost and time cost.

[0019] 3. In the standard vertical display cabinet refrigeration system base assembly with a freely switchable cabinet, the condensed water of the evaporation component is introduced into the water receiving box through the evaporator drain pipe. An evaporation water heating pipe is installed at the inner bottom of the water receiving box. The evaporation water heating pipe is heated by electricity and is distributed on the inner wall of the bottom of the water receiving box. This design can quickly evaporate the condensed water in the water receiving box, avoiding the influence of the accumulation of condensed water on the normal operation of the refrigeration system, reducing the risk of failures caused by the accumulation of condensed water, and ensuring the stability and reliability of the refrigeration system.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1 The present invention provides a standard vertical display cabinet refrigeration system base assembly with a box that can be freely switched, as Figures 1-4 shown, including an outer shell 1. The outer shell 1 is located at the bottom of the display cabinet. A compressor 2, a condenser 3, and an evaporation assembly 4 are installed inside the outer shell 1. A lower front cover 7 is installed on one side of the outer shell 1. The condenser 3 sucks air on one side, dissipates heat on the other side, and cools the compressor 2 through a condensing fan 5. The air flow blows directly on the lower front cover 7 after passing through the compressor 2, and forms an air flow through the hot air outlet 72 at the top of the lower front cover 7 to blow onto the upper display cabinet glass door, so that the condensation on the glass door evaporates through high temperature. The condensed water of the evaporation assembly 4 is introduced into the water receiving box 8 through the evaporator drain pipe 44. An evaporation water heating pipe 81 is installed at the inner bottom of the water receiving box 8. This structure not only effectively cools the compressor 2 through the cooperation of the condenser 3 and the condensing fan 5, but also uses the hot air flow to blow on the display cabinet glass door, effectively solving the problem of condensation on the glass door and improving the display effect and safety. At the same time, the condensed water generated by the evaporation assembly 4 is efficiently collected and evaporated through the evaporation water heating pipe 81, avoiding the influence of condensed water accumulation on the refrigeration system.

[0024] In this embodiment, a water receiving tank 71 is provided at the top of the lower front cover 7 to prevent the condensation water droplets on the glass door from dripping. The water outlet on one side of the water receiving tank 71 is connected to the water receiving box 8 through a pipeline. The design of the water receiving tank 71 further prevents the condensation water on the glass door from directly dripping, but introduces it into the water receiving box 8 through a pipeline, and cooperates with the condensate treatment system in the first paragraph of the technology, improving the overall water treatment efficiency.

[0025] Specifically, a number of positioning pins 11 are installed on the top of the outer shell 1, and the positioning pins 11 are matched with the positioning holes at the bottom of the display cabinet. The cooperation between the positioning pins 11 and the positioning holes at the bottom of the display cabinet ensures the precise docking between the base assembly of the refrigeration system and the display cabinet body, improving the installation efficiency and stability.

[0026] Furthermore, the evaporation assembly 4 includes an evaporator foam outer shell 47. An evaporator 41 is installed inside the evaporator foam outer shell 47, and an evaporation fan 45 is installed on one side of the evaporator 41. The evaporator foam outer shell 47 provides a good heat preservation environment for the evaporator 41, improving the refrigeration efficiency. The evaporation fan 45 promotes the circulation of cold air, making the refrigeration effect more uniform.

[0027] Furthermore, a number of rollers 12 are installed at the bottom of the outer shell 1. The design of the rollers 12 enables the base assembly of the refrigeration system to be conveniently moved, facilitating the installation, debugging, and maintenance of the equipment.

[0028] Furthermore, an intelligent controller 13 is installed on the inner wall of one side of the outer shell 1. The intelligent controller 13 is electrically connected to the compressor 2, the condenser 3, and the evaporation assembly 4 respectively. The intelligent controller 13 realizes the intelligent control of the refrigeration system, and can automatically adjust the refrigeration parameters according to the actual needs inside the display cabinet, improving the automation level and operation efficiency of the equipment.

[0029] Embodiment 2 In order to further improve the effect of the evaporator, on the basis of Embodiment 1, an evaporator cover 46 is installed on the top of the evaporator foam outer shell 47. An air outlet 43 is provided in the middle of the evaporator cover 46, and air inlets 42 are provided on both sides of the evaporator cover 46. The air outlet 43 is communicated with the cold air channel of the display cabinet, and the air inlets 42 are connected to the hot air outlets of the display cabinet. The design of the evaporator cover 46 enables cold air to enter the interior of the display cabinet more smoothly, and at the same time, hot air can be effectively discharged, forming a good air flow circulation and improving the refrigeration effect.

[0030] Furthermore, sealing sleeves are sleeved at the joints of the air inlets 42 and the air outlet 43 with the display cabinet. The setting of the sealing sleeves effectively prevents the leakage of air flow, ensuring the sealing and stability of the refrigeration system.

[0031] Furthermore, the evaporation water heating tube 81 is heated by electricity, and the evaporation water heating tube 81 is distributed on the inner wall of the bottom of the water receiving box 8. This structure further ensures that the condensed water in the water receiving box 8 can be quickly evaporated, avoiding the influence of the accumulation of condensed water on the refrigeration system.

[0032] Furthermore, the side of the top of the outer shell 1 is clamped and matched with the outer side of the bottom of the display cabinet through a lock. The design of the lock makes the connection between the base assembly of the refrigeration system and the display cabinet body more firm and reliable, and at the same time facilitates disassembly and replacement.

[0033] The cold air is introduced by designing an opening in the middle of the rear part of the top of the assembly, and the cold air from the evaporator is passed through the air duct inside the connectable box body to blow the cold air into the cabinet interior. The air blows to the top of the box body through the air duct inside the box body. This design enables the cold air to be evenly distributed to all corners of the display cabinet, improving the refrigeration effect and uniformity.

[0034] According to the principle of cold air descending inside the box body, the air duct inside the box body blows the air to the top of the box body first, and then it goes down from the top. There are air outlets on the left and right sides at the bottom of the box body. The hot air inside the box is sucked into the base by the evaporation fan 45 and cooled by the evaporator 41. A complete cold and hot air circulation system is formed, making the temperature inside the display cabinet more stable and uniform.

[0035] For the related box body, according to the different heights of the box body, relay fans can be placed at different positions according to the air duct in the box body. There is an air volume adjustment cover plate at the air outlet. The angle of the baffle can be adjusted according to different temperature requirements to adjust the air volume size, and the air duct can be directly closed. The outlet of the refrigeration air duct adopts segmented control. The air ducts at the bottom and middle are controlled according to the temperature of the corresponding probes and can be opened and closed at any time. And the user can make segmented temperature control areas inside the box according to the needs. To cooperate with the segmented control, the air outlet adopts a segmented louver design. It is convenient to control the opening and closing and hardly occupies the display space inside the box.

[0036] The operation of the standard refrigeration system base system and the control system of the upper box body can be automatically matched, and the corresponding control mode can be automatically selected to control the operation time of the compressor, the operation time of the fan and its temperature control mode.

[0037] When the standard vertical display cabinet refrigeration system base assembly of the present invention is in use, first, when the standard vertical display cabinet refrigeration system is started, the compressor 2 starts to work, compresses the refrigerant into high-temperature and high-pressure gas, and transports it to the condenser 3. One side of the condenser 3 sucks air, and the other side dissipates heat. The condensation fan 5 runs synchronously, promoting the outside air to quickly flow through the condenser 3, taking away the heat released by the refrigerant, and changing the refrigerant from the high-temperature and high-pressure gas state to the high-pressure liquid state.

[0038] At the same time, the air flow generated by the condensation fan 5 takes away the heat generated by the compressor 2 when passing through the compressor 2, effectively cooling the compressor 2. Then the hot air flow blows directly to the lower front cover 7, forms an air flow through the hot air outlet 72 at the top of the lower front cover 7, and blows towards the glass door of the display cabinet, so that the condensation on the glass door evaporates under the action of the high-temperature air flow, effectively solving the problem of glass door condensation and improving the display effect and safety.

[0039] The refrigerant in a high-pressure liquid state enters the evaporator 41 in the evaporation assembly 4 through a pipeline. The evaporator foamed outer shell 47 provides a good heat insulation environment for the evaporator 41, reducing heat exchange and improving the refrigeration efficiency. The evaporation fan 45 operates to prompt air to enter the interior of the evaporator foamed outer shell 47 from the air inlets 42 on both sides of the evaporator cover 46. The air exchanges heat with the low-temperature refrigerant in the evaporator 41, and the air is cooled to form cold air. The cold air is discharged from the air outlet 43 in the middle of the evaporator cover 46, and the air outlet 43 is communicated with the cold air channel of the display cabinet. The cold air enters the interior of the display cabinet through the cold air channel.

[0040] After the cold air enters the interior of the display cabinet, according to the principle that cold air descends, it flows downward from the top of the cabinet body and is evenly distributed in all corners of the display cabinet, reducing the temperature inside the display cabinet. There are air outlet holes on the left and right sides at the bottom of the cabinet body. The hot air inside the cabinet is sucked into the base by the evaporation fan 45 and cooled by the evaporator 41, forming a complete hot and cold air circulation system, making the temperature inside the display cabinet more stable and uniform.

[0041] During the operation of the evaporation assembly 4, condensed water is generated. The condensed water is introduced into the water receiving box 8 through the evaporator drain pipe 44. An evaporation water heating pipe 81 is installed at the inner bottom of the water receiving box 8. The evaporation water heating pipe 81 uses an electric heating method and is distributed on the inner wall of the bottom of the water receiving box 8 to heat and evaporate the condensed water in the water receiving box 8, avoiding the influence of the accumulation of condensed water on the refrigeration system.

[0042] A number of positioning pins 11 are installed at the top of the outer shell 1. The positioning pins 11 cooperate with the positioning holes at the bottom of the display cabinet to ensure the precise docking between the refrigeration system base assembly and the display cabinet body, improving the installation efficiency and stability. The top side of the outer shell 1 is clamped and matched with the outer side of the bottom of the display cabinet through a lock, making the connection more firm and reliable, and at the same time facilitating disassembly and replacement.
