Description

Technical Field

[0001] This utility model relates to the field of refrigerated display cabinet technology, specifically a temperature-controlled refrigerated display cabinet based on copper tube refrigeration. Background Technology

[0002] Refrigerated display cases are indispensable equipment in modern commerce, especially in the retail and catering industries, and are widely used for the low-temperature display and sale of beverages, dairy products, fresh food, and other goods. Traditional refrigerated display cases mostly use direct cooling or air cooling technology, and their core evaporators are usually made of aluminum or alloy materials. The evaporators of most display cases have poor corrosion resistance, especially when used for a long time in high humidity environments. They are prone to reduced cooling efficiency, leakage, or even damage due to corrosion from condensation, food juices, etc., resulting in high maintenance and replacement costs.

[0003] Since most refrigerated display cases have top openings, their temperature is easily affected by the external environment, and a large amount of cold air is lost, resulting in unstable internal temperature. This not only increases the compressor load and energy consumption but may also affect the quality of stored fresh food. Furthermore, fresh food is often placed with the boxes directly in contact with the bottom of the cabinet. Inconsistent box heights can affect the display effect and cause condensation buildup, making subsequent cleaning difficult. Therefore, we propose a temperature-controlled refrigerated display case based on copper pipe refrigeration. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a temperature-controlled refrigerated display cabinet based on copper tube refrigeration. By adopting a corrosion-resistant copper tube evaporator core, the durability and reliability of the equipment are significantly improved. Combined with an intelligent temperature-controlled curtain and air curtain system, it can effectively isolate the exchange of internal and external air, achieving precise temperature control and high energy efficiency. The sliding support rod can place trays of different heights, thereby improving the display effect of fresh food and effectively solving the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a temperature-controlled refrigerated display cabinet based on copper pipe refrigeration, comprising a cabinet body and ventilation holes;

[0006] Cabinet: An electrical box is fixed to the bottom surface. A compression refrigeration module is placed inside the bottom surface of the electrical box. A shell is fixed to the top surface of the electrical box. A copper tube evaporator is installed inside the shell. Both ends of the front side of the shell are connected to a base. A fan is placed inside the base. The copper tube evaporator and the compression refrigeration module are connected through a tube. Vent holes are evenly opened on the bottom surface of the cabinet and the top surface of the electrical box and are connected. A temperature control unit is provided on the rear side of the cabinet. An adjustment unit is provided inside the cabinet.

[0007] The system also includes a controller, which is fixed on the left side of the cabinet. The input terminals of the compression refrigeration module and the fan are electrically connected to the output terminal of the controller, and the input terminal of the controller is electrically connected to the output terminal of an external power supply.

[0008] The compressor refrigeration module works with the copper tube evaporator to generate cold air, which is then blown into the cabinet through the ventilation holes by a fan to keep fresh food refrigerated. Compared with traditional aluminum evaporators, the copper tube evaporator has excellent corrosion resistance, oxidation resistance and higher mechanical strength, which can effectively resist the erosion of condensate and humid environments, greatly extending its service life.

[0009] Furthermore, the temperature control unit includes a housing, a shielding curtain, a bracket, a linear motor, a take-up roller, a motor, and a motor frame. The housing is fixed to the rear side of the cabinet. The motor frame is located on the left side of the housing, and a motor is fixed to the surface of the motor frame. The output shaft of the motor is connected to one end of the take-up roller, which is rotatably installed inside the housing. The outer side of the take-up roller is connected to one end of the shielding curtain. The other end of the shielding curtain passes through a slot on the rear side of the cabinet and connects to the rear side of the bracket. The linear motor is fixed inside a groove on the left side of the cabinet. The surface of the linear motor's actuator is connected to the end of the bracket. The linear motor and its input end are electrically connected to the output end of the controller. Activating the linear motor, in conjunction with the motor, causes the shielding curtain to cover the top surface of the cabinet. This effectively prevents cold air loss when the refrigerated display cabinet is not in use, thereby reducing energy consumption.

[0010] Furthermore, the temperature control unit also includes a temperature sensor and an air curtain. There are two temperature sensors, which are fixed on the left and right sides of the cabinet interior, respectively. The air curtain is fixed on the rear side of the top surface of the cabinet. The output of the temperature sensor is electrically connected to the input of the controller, and the input of the air curtain is electrically connected to the output of the controller. The temperature sensor can detect the temperature inside the cabinet and adjust the temperature inside the cabinet in real time based on the detected data. The air curtain forms an air curtain barrier on the top surface of the cabinet to prevent the exchange of cold air with hot air outside during the use of the refrigerated display case, and also to prevent flies from entering and affecting the quality of fresh food.

[0011] Furthermore, the adjustment unit includes a screw, a fixed rail, a slide, a rubber pad, and a support rod. There are two fixed rails, which are respectively installed on the left and right sides inside the cabinet. A slide is slidably installed on the outer side of the fixed rail. The inner side of the slide is connected to the end of the support rod. A rubber pad is glued to the top surface of the support rod. A screw is threaded into the screw hole on the top surface of the slide. The slide slides on the outer side of the fixed rail to adjust the position of the support rod. This allows display boxes of different heights to be snapped together to increase the uniformity of the display. At the same time, it can also prevent the display boxes from being placed directly against the bottom surface of the cabinet, which would cause condensation to accumulate.

[0012] Furthermore, it also includes lighting and a display screen. The lighting is fixed to the rear side inside the cabinet, and the display screen is fixedly installed at the bottom of the rear side of the cabinet. The input terminals of the lighting and the display screen are electrically connected to the output terminal of the controller. The lighting can illuminate the fresh food to enhance its display effect and attractiveness. At the same time, the display screen can display information such as the current temperature and set temperature inside the cabinet in real time for easy viewing by personnel.

[0013] Furthermore, it also includes a panel frame and an air guide plate. The panel frame is fixed inside the cabinet, and the air guide plate is slidably installed inside the panel frame. The air guide plate inside the panel frame can guide and divert cold air, which can ensure that the temperature in each area of ​​the cabinet is more uniform and stable.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This temperature-controlled refrigerated display cabinet based on copper pipe refrigeration has the following advantages:

[0015] 1. By activating the compression refrigeration module in conjunction with the copper tube evaporator, cold air is generated and then blown into the cabinet through vents by a fan to refrigerate and maintain fresh food. Compared to traditional aluminum evaporators, the copper tube evaporator has excellent corrosion resistance, oxidation resistance, and higher mechanical strength, effectively resisting the erosion of condensate and humid environments, greatly extending its service life.

[0016] 2. By starting a linear motor in conjunction with the motor, the shielding curtain is placed on the top surface of the cabinet. This effectively prevents the loss of cold air when the refrigerated display cabinet is not in use, thereby reducing energy consumption. The air curtain machine forms an air curtain barrier on the top surface of the cabinet to prevent the exchange of cold air with outside hot air during the use of the refrigerated display cabinet. At the same time, it can also prevent flies from entering and affecting the quality of fresh food.

[0017] 3. The position of the support rod can be adjusted by sliding the carriage on the outside of the fixed rail. This allows for the snap-fit ​​placement of display boxes of different heights to increase the uniformity of the display, and also prevents the display boxes from being placed directly against the bottom of the cabinet, which would cause condensation to accumulate.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This embodiment provides a technical solution: a temperature-controlled refrigerated display cabinet based on copper pipe refrigeration, including a cabinet body 1 and a ventilation hole 10;

[0025] Cabinet 1: An electrical box 4 is fixed to the bottom surface. A compression refrigeration module 5 is placed inside the bottom surface of the electrical box 4. A shell 7 is fixed to the top surface inside the electrical box 4. A copper tube evaporator 6 is installed inside the shell 7. Both ends of the front side of the shell 7 are connected to a base 8. A fan 9 is placed inside the base 8. The copper tube evaporator 6 and the compression refrigeration module 5 are connected through tubes. Vent holes 10 are evenly opened on the bottom surface of cabinet 1 and the top surface of electrical box 4 and are connected. A temperature control unit 2 is provided on the rear side of cabinet 1. The temperature control unit 2 includes a shell 21, a shielding curtain 22, a bracket 23, a linear motor 24, a winding roller 25, a motor 26, and a motor frame 27. The shell 21 is fixed to the rear side of cabinet 1. The left side of the shell 21... A motor frame 27 is provided, and a motor 26 is fixed to the surface of the motor frame 27. The output shaft of the motor 26 is connected to one end of a take-up roller 25, which is rotatably mounted inside the outer casing 21. The outer side of the take-up roller 25 is connected to one end of a curtain 22, and the other end of the curtain 22 passes through a slot on the rear side of the cabinet 1 and is connected to the rear side of a bracket 23. A linear motor 24 is fixed inside a groove on the left side of the cabinet 1, and the surface of the actuator of the linear motor 24 is connected to the end of the bracket 23. The input ends of the linear motor 24 and the motor 26 are electrically connected to the output end of the controller 15. When the linear motor 24 is activated, it works with the motor 26 to cover the top surface of the cabinet 1 with the curtain 22. This effectively prevents cold air from entering the refrigerated display case when it is not in use. To reduce energy loss, the temperature control unit 2 also includes a temperature sensor 28 and an air curtain 29. There are two temperature sensors 28, fixed to the left and right sides inside the cabinet 1 respectively. The air curtain 29 is fixed to the rear side of the top surface of the cabinet 1. The output of the temperature sensor 28 is electrically connected to the input of the controller 15, and the input of the air curtain 29 is electrically connected to the output of the controller 15. The temperature sensor 28 can detect the temperature inside the cabinet 1 and adjust the temperature in real time based on the detected data. The air curtain 29 forms an air curtain barrier on the top surface of the cabinet 1 to prevent the exchange of cold air with hot air during the use of the refrigerated display case, and also to prevent flies from entering and affecting fresh food. To ensure quality, the cabinet 1 has an internal adjustment unit 3. The adjustment unit 3 includes a screw 31, a fixed rail 32, a slide 33, a rubber pad 34, and a support rod 35. There are two fixed rails 32, which are installed on the left and right sides inside the cabinet 1 respectively. The slide 33 is slidably installed on the outside of the fixed rail 32. The inner side of the slide 33 is connected to the end of the support rod 35. The top surface of the support rod 35 is glued with a rubber pad 34. The screw 31 is installed in the screw hole on the top surface of the slide 33. The slide 33 slides on the outside of the fixed rail 32 to adjust the position of the support rod 35. This allows display boxes of different heights to be snapped together to increase the uniformity of the display. At the same time, it can also prevent the display boxes from being placed directly against the bottom of the cabinet, which would cause condensation to accumulate.

[0026] The system includes a controller 15, which is fixed to the left side of the cabinet 1. The input terminals of the compression refrigeration module 5 and the fan 9 are electrically connected to the output terminal of the controller 15, and the input terminal of the controller 15 is electrically connected to the output terminal of an external power supply. The compression refrigeration module 5, in conjunction with the copper tube evaporator 6, generates cold air, which is then blown into the interior of the cabinet 1 through the vent 10 by the fan 9 to refrigerate and maintain fresh food. Compared to traditional aluminum evaporators, the copper tube evaporator 6 has excellent corrosion resistance, oxidation resistance, and higher mechanical strength, effectively resisting the erosion of condensate and humid environments, greatly extending its service life. The system also includes a lighting fixture 11 and a display screen 1. 2. The lighting lamp 11 is fixed inside the rear side of the cabinet 1, and the display screen 12 is fixedly installed at the bottom of the rear side of the cabinet 1. The input terminals of the lighting lamp 11 and the display screen 12 are electrically connected to the output terminal of the controller 15. The lighting lamp 11 can illuminate the fresh food to enhance its display effect and attractiveness. At the same time, the display screen 12 can display information such as the current temperature and set temperature inside the cabinet in real time for easy viewing by personnel. It also includes a shelf 13 and an air guide plate 14. The shelf 13 is fixed inside the cabinet 1, and the air guide plate 14 is slidably installed inside the shelf 13. The air guide plate 14 inside the shelf 13 can guide and divert the cold air, which can ensure that the temperature in each area inside the cabinet is more uniform and stable.

[0027] The working principle of the temperature-controlled refrigerated display cabinet based on copper tube refrigeration provided by this utility model is as follows: First, the slide 33 slides outside the fixed rail 32 to adjust the position of the support rod 35. This allows for the snap-fit ​​placement of display boxes of different heights to increase the uniformity of the display, and also prevents the display boxes from directly contacting the bottom of the cabinet and causing condensation to accumulate. The compression refrigeration module 5 is activated in conjunction with the copper tube evaporator 6 to generate cold air, which is then blown into the interior of the cabinet 1 through the ventilation hole 10 by the fan 9 to keep fresh food refrigerated. The air guide plate 14 inside the shelf 13 can guide and distribute the cold air, which can ensure that the temperature in each area of ​​the cabinet is more uniform and stable. The copper tube evaporator 6 used is different from the traditional aluminum evaporator. Compared to other types of refrigerators, this one has excellent corrosion resistance, oxidation resistance, and higher mechanical strength, effectively resisting the erosion of condensate and humid environments, greatly extending its service life. Then, the linear motor 24, in conjunction with the motor 26, is activated to cover the top of the cabinet 1 with the curtain 22. This effectively prevents the loss of cold air when the refrigerated display case is not in use, thereby reducing power consumption. Alternatively, the air curtain machine 29 can be activated to form an air curtain barrier on the top of the cabinet 1 to prevent the exchange of cold air with the outside hot air during the use of the refrigerated display case. It can also prevent flies from entering and affecting the quality of fresh food. The temperature sensor 28 can detect the temperature inside the cabinet 1 and adjust the temperature inside the cabinet 1 in real time based on the detected data.

[0028] It is worth noting that the controller 15 disclosed in the above embodiments is provided with buttons on its surface corresponding to the linear motor 24, motor 26, temperature sensor 28, air curtain machine 29, compression refrigeration module 5, fan 9, lighting lamp 11, and display screen 12. The controller 15 controls the operation of the linear motor 24, motor 26, temperature sensor 28, air curtain machine 29, compression refrigeration module 5, fan 9, lighting lamp 11, and display screen 12 using methods commonly used in the prior art.
