Abstract
Description
Technical Field
[0001] This utility model relates to the field of refrigeration equipment technology, and more specifically, it relates to an antibacterial cooked food display cabinet. Background Technology
[0002] In the prepared food retail industry, display cases are one of the core pieces of equipment, requiring them to simultaneously meet three core needs: "clear display," "low-temperature preservation," and "hygiene and safety." However, existing prepared food display cases have some problems in practical use: Insufficient antibacterial ability: Traditional display cabinets rely solely on refrigeration temperature to inhibit bacteria, but the surfaces of cooked food (especially products that are frequently exposed to air) are still prone to the growth of pathogenic bacteria such as E. coli and Staphylococcus aureus. In particular, the risk of bacterial residue is high in easily accessible areas such as display cabinet placement tables and operating windows, and long-term use can easily lead to food safety hazards.
[0003] Fogging of glass affects the display: There is a temperature difference between the inside and outside of the display case (the temperature inside the case is usually 2-8℃, while the ambient temperature is mostly 20-25℃). Since cooked food is exposed to high humidity and temperature when it comes out of the pot, water vapor is easily condensed on the inside of the front and side glass panels, which obstructs the consumer's view, reduces the product display effect, and requires temporary suspension of use for manual wiping, affecting sales efficiency. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0019] like Figure 1 As shown, this utility model provides an antibacterial cooked food display cabinet, including a refrigerated display cabinet, a defogging mechanism, and an antibacterial mechanism; The refrigerated display case includes an equipment cabinet 1 and a display cabinet 2 fixedly installed on the top of the equipment cabinet 1, with nitrile rubber sealing strips at the joints to prevent cold air leakage and external dust from entering.
[0020] The frames of both the equipment cabinet 1 and the display cabinet 2 are made of food-grade stainless steel, which has good corrosion resistance and is easy to clean.
[0021] Specifically, the equipment cabinet 1 has a rectangular structure with a layered / cavity design. It is divided into a cooling cavity, a temperature control cavity, and an ozone generation cavity by galvanized steel plate partitions. The various cavities are separated by baffles. The specific components and configurations are as follows: A fully enclosed scroll compressor is installed in the refrigeration chamber, located on the bottom left side of equipment cabinet 1 (secured by shock-absorbing rubber pads), to provide cooling power and regulate the temperature of display cabinet 2. The evaporator, located at the top of the refrigeration chamber, is connected to the compressor via copper tubing, absorbing heat through refrigerant evaporation to lower the internal temperature of display cabinet 2. The condenser, located on the right side of the refrigeration chamber, is equipped with an axial fan to condense the refrigerant and release heat, expelling heat from equipment cabinet 1. A dryer filter, installed on the copper tubing between the condenser and evaporator, filters moisture and impurities from the refrigerant to prevent pipe blockage.
[0022] The temperature control chamber is equipped with a digital temperature controller, located on the left side of the middle of the equipment cabinet 1. The panel is embedded in the front of the cabinet, which is the rear side. It monitors the temperature inside the display cabinet 2 in real time, controls the start and stop of the compressor, and maintains a stable temperature. The temperature sensor is located below the top cabinet plate 4 inside the display cabinet 2 and is fixed by a bracket. It is used to collect the temperature signal inside the cabinet and transmit it to the temperature controller. The overload protector is connected in series with the compressor power cord. When the compressor current is too high or the temperature is too high, it automatically cuts off the power supply to protect the equipment.
[0023] An ozone generator is installed in the ozone generating chamber, located on the right side of the middle of the equipment cabinet 1. A ventilation duct is installed on the top of the chamber to generate ozone, which is then transported to the edge of the placement table through the ventilation duct to assist in sterilization. An ozone concentration sensor is located at the outlet of the ozone generating chamber to detect the ozone output concentration. When the concentration exceeds 0.3 mg / m³, the generator is triggered to stop to prevent excessive ozone.
[0024] The bottom of the cabinet is equipped with four casters (100mm in diameter) with brakes for easy movement and securing of the equipment.
[0025] Specifically, equipment cabinet 1 adopts existing refrigeration cabinet technology, which uses high-efficiency and energy-saving intelligent compressors and evaporators, connected to refrigeration pipes and circuits, to ensure the normal operation of the refrigeration system. Based on the volume and usage requirements of the refrigeration cabinet, a reasonable refrigeration temperature range is set, which can quickly lower and stabilize the temperature between the top of equipment cabinet 1 and display cabinet 2 within a suitable refrigeration temperature range, thereby inhibiting the growth and reproduction of microorganisms.
[0026] The surface of the placement platform at the top of cabinet 1 is coated with an antibacterial coating. This antibacterial coating is a nano-coating with antibacterial properties, such as the KL-6638 nano-silver antibacterial coating. This coating conforms to the GB 4806.1-2016 standard, with nano-silver as the core antibacterial component. The coating thickness is 8-12μm, and the antibacterial rate against Escherichia coli and Staphylococcus aureus is ≥99.9%. This coating can continuously release antibacterial factors, inhibiting the adhesion and growth of microorganisms on the surface. The food-grade stainless steel cabinet and easy-to-clean antibacterial coating make the refrigerator easy to clean and maintain, ensuring the hygiene of the equipment.
[0027] The display cabinet 2 includes a front glass panel 3, a top cabinet panel 4, a rear operating window 5, and two side glass panels 6 that are connected accordingly; each component is spliced and fixed by an aluminum alloy frame, and foam sealing strips are pasted on the inside of the frame to ensure the airtightness of the cabinet.
[0028] The top cabinet panel 4 is made of 304 stainless steel. The bottom is secured with screws to the brackets for the lighting lamp 23 and the ultraviolet germicidal lamp 7. A 5mm thick layer of insulation cotton is pasted on the surface of the top cabinet panel 4 to reduce heat loss. The lighting lamp 23 and the ultraviolet germicidal lamp 7 are mounted using brackets. like Figure 2 As shown, the rear operation window 5 includes a fixed window frame 21 and at least two glass sliding windows 22. The front side of the top edge of the fixed window frame 21 is fixedly connected to the rear side of the top cabinet plate 4, the bottom edge of the fixed window frame 21 is fixedly connected to the rear side of the top surface of the equipment cabinet 1, and the front sides of the two sides of the fixed window frame 21 are respectively fixedly connected to the rear sides of the two side glass plates 6. The glass sliding windows 22 are slidably installed between the top edge and the bottom edge of the fixed window frame 21, and both sides of the glass sliding windows 22 are equipped with sealing strips.
[0029] The front glass panel 3, the side glass panel 6, and the sliding glass window 22 are all multi-layer hollow tempered glass panels. The inner glass layer (facing the inside of the cabinet) is coated with an anti-fog film, which can initially reduce water vapor condensation. The hollow layer is filled with dry air to reduce heat conduction and reduce fogging caused by temperature differences.
[0030] The antibacterial mechanism includes an ultraviolet germicidal lamp 7, which is located on the bottom surface of the top cabinet panel 4. When turned on, the ultraviolet lamp 7 irradiates the air inside the cabinet and the surface of cooked food with ultraviolet light, destroying the DNA structure of microorganisms and achieving the purpose of sterilization and disinfection. The antibacterial mechanism also includes an ozone generator, which is installed inside equipment cabinet 1. The ozone generator's outlet is connected to the edge of the display stand. A small ozone generator is installed inside equipment cabinet 1 to produce an appropriate amount of ozone, which is then introduced into the display cabinet 2 through the outlet. Ozone has strong oxidizing properties and can effectively kill microorganisms such as bacteria, mold, and viruses.
[0031] Through the synergistic effect of ultraviolet germicidal lamps, ozone generators, and antibacterial coatings, microorganisms in the refrigerator can be comprehensively and efficiently inhibited and killed, greatly extending the shelf life of cooked food.
[0032] like Figure 3 As shown, the defogging mechanism includes a defogging scraper 8 and two sets of drive mechanisms 9. The drive mechanisms 9 are installed on the inner front part of the side glass panel 6. The two ends of the defogging scraper 8 are connected to the drive mechanisms 9 respectively. The drive mechanisms 9 drive the defogging scraper 8 to move up and down along the inner side of the front glass panel 3.
[0033] The drive mechanism 9 includes a moving track 10 and an electric moving seat. A water-absorbing sponge 11 is provided on the side of the defogging scraper 8 facing the front glass panel 3. The two ends of the defogging scraper 8 are detachably connected to two electric moving seats respectively. The moving track 10 is fixedly installed on the inner front part of the side glass panel 6. The electric moving seat is slidably connected to the moving track 10.
[0034] like Figure 4 , 5 As shown in Figure 6, the defogging scraper 8 includes a mounting rod 12, a side pressure plate strip 13, two sets of strip-shaped absorbent sponges 11, and a flexible water scraper 14. The two ends of the mounting rod 12 are used to connect to the electric moving base. The side pressure plate strip 13 is fixedly connected to the front side of the mounting rod 12. The two sets of strip-shaped absorbent sponges 11 are respectively installed at the top and bottom of the front side of the side pressure plate strip 13. The flexible water scraper 14 is installed in the middle of the front side of the side pressure plate strip 13 and is sandwiched in the middle of the two sets of strip-shaped absorbent sponges 11.
[0035] The electric moving base includes a moving drive base 15 and a mounting base 16. One side of the moving drive base 15 is slidably connected to the moving track 10, and the other side of the moving drive base 15 is fixedly connected to one end of the mounting base 16. The top of the end of the mounting base 16 facing away from the moving drive base 15 is provided with a placement groove 17 that matches the end of the mounting rod 12. Both ends of the mounting rod 12 are provided with mounting holes that extend through in the front-back direction. The mounting base 16 is also provided with a slot at the position corresponding to the mounting holes. The rear side of the mounting base 16 is punched to form a positioning hole, and the front side of the mounting base 16 is not completely punched to form a positioning groove 18. A magnetic suction piece 19 is fixedly provided at the bottom of the positioning groove 18. After the mounting rod 12 is placed into the placement groove 17, the pin 20 with a magnet at the front end is inserted into the positioning hole, the mounting hole, and the positioning groove 18 in sequence, and the magnetic attraction of the magnet and the magnetic suction piece 19 limits the installation. The magnetic block of the pin 20 and the magnetic piece 19 of the positioning groove 18 are magnetically attracted and fixed, realizing the quick installation of the defogging scraper 8; when disassembling, simply pull the pin 20 backward, without tools.
[0036] Specifically, the electric moving seat and the moving track 10 directly adopt the existing track and moving seat, and the moving track 10 is made of aluminum alloy and is fixed inside the side glass plate 6. A DC geared motor and gear are set in the moving seat, and a corresponding rack is set in the track. The gear is connected to the output shaft of the motor, and the motor is controlled by the corresponding controller, thereby realizing the movement control of the defogging scraper 8.
[0037] The flexible water wiper 14 is made of food-grade silicone. When the defogger 8 moves up or down, it wipes away water mist from the front glass panel 3. The collected water flow is absorbed by the water-absorbing sponge 11.
[0038] The entire defogging scraper 8 and the electric moving base are connected by a slot and a pin 20, which allows for easy disassembly and installation. In general, in practical applications, the defogging scraper 8 needs to be disassembled periodically for cleaning and disinfection.
[0039] The advantages of this invention are: enhanced antibacterial performance; through a triple antibacterial design of "ultraviolet sterilization + food-grade antibacterial coating + ozone-assisted sterilization," it effectively inhibits bacterial growth inside the display case and in contact areas, meeting food safety requirements. Automatic defogging ensures clear display; through an electrically driven defogging scraper 8 structure, it automatically cleans water mist from the inside of the front glass panel 3, ensuring a clear display.
