Description

Technical Field

[0001] The invention relates to the technical field of refrigeration display equipment, in particular to a vertical micro-freezing display cabinet. Background Art

[0002] Micro-freezer display cabinets are generally used to display goods, samples, products or other shelves that need to be displayed. Micro-freezers are also called soft freezers. According to national standards, the temperature of the soft freezer is 0 to -7°C. When the internal temperature is higher than this temperature, the refrigeration equipment starts, and when it is lower than this temperature, the refrigeration equipment is shut down, thereby ensuring that the internal temperature is maintained between 0 and -7°C.

[0003] When the existing vertical micro-freezing display cabinet is in use, in order to ensure that the internal temperature of different display layers of the display cabinet is maintained between 0 and -7°C, the refrigeration equipment will be repeatedly turned on and off, which will greatly reduce the service life of the refrigeration equipment. In the micro-freezing state, the display cabinet generally stores meat, fish and processed foods such as yogurt, pasta, butter, cheese, etc. Long-term micro-freezing will cause blood to appear in the stored meat and condensation water to appear on the packaging shell. These liquids will drip into the display cabinet. The accumulation of liquid affects the appearance of the interior of the display cabinet and affects the sale of goods. In order to sell the goods, the display cabinet generally has lighting equipment. Lights of different brightness produce different effects on the goods. Too bright or too dark is not good.

[0022] 3. The present invention increases the design of the intelligent control system of the light source, and drives the brightness setting module to be used through the light sensor. The brightness setting module sets the expected brightness and the brightness value for automatic opening and closing. When the natural light sensing module senses that the external natural light brightness is low, it drives the lighting device switch module to be used to turn on the lighting device. When the artificial light sensing module senses that the brightness inside the display cabinet is low or high, it drives the current control module to control. The current control module controls the current to adjust the brightness of the lighting device, thereby maintaining the brightness of the lighting device at a constant level, and realizes the brightness control of the lighting device according to the comprehensive situation of the external environment and the internal light. It also realizes that while controlling the brightness of the lighting device, the use of electric energy is reduced, and the use of the display cabinet is more environmentally friendly and energy-saving.
