Description

Technical Field

[0001] This utility model relates to the field of refrigerated display cabinet technology, specifically an environmentally friendly three-door refrigerated display cabinet. Background Technology

[0002] Refrigerated display cases are appliances used to refrigerate and display food, medicine, and other items. They are commonly used in shopping malls, supermarkets, convenience stores, and other similar locations. They can refrigerate and store a variety of products, including cakes, fruits, vegetables, fresh meat, and medicine. Traditional refrigerated display cases typically use direct cooling or air-cooling refrigeration systems, which suffer from problems such as uneven temperature distribution and high energy consumption.

[0003] During the use of refrigerated display cases, the lack of a cold air circulation structure leads to high power consumption. Furthermore, when the cabinet doors are frequently opened and closed, condensation will form on their surface. This condensation on the cabinet doors will cause cold air to escape, resulting in an increase in the temperature inside the refrigerated display case, which will also lead to energy waste. To address this issue, we propose an environmentally friendly three-door refrigerated display case. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide an environmentally friendly three-door refrigerated display cabinet. It adopts a refrigeration chamber combined with a dual-fan design to improve the efficiency of cold air circulation, which can reduce power consumption and thus indirectly reduce carbon emissions. The lifting and lowering moisture-absorbing cotton can quickly remove the fog on the surface of the cabinet door, thereby effectively reducing energy consumption and environmental pollution. It is in line with the development trend of green cold chain and can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly three-door refrigerated display cabinet, comprising a cabinet body and a shelf;

[0006] Cabinet: The top surface of the cabinet is provided with a cooling chamber, the bottom surface of which has an air hole that communicates with the interior of the cabinet. A heat exchanger is installed inside the cooling chamber. A limit bracket is fixed to the rear side of the shelf, and the limit bracket is slidably installed with a limit groove on the rear side of the cabinet. A display screen is installed at the top of the front side of the cabinet. Cabinet doors are evenly hinged to the front side of the cabinet. A circulation unit is provided inside the cooling chamber. A defogging unit is provided inside the cabinet.

[0007] It also includes a controller, which is located on the left side of the cabinet. The input terminal of the display screen is 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 heat exchanger is connected to an external compressor. When the external compressor is started, refrigerant is delivered into the heat exchanger to cool the inside of the cabinet, thus refrigerating and displaying the items on the top of the shelf.

[0009] Furthermore, the circulation unit includes a placement base, an air inlet, dehumidifying cotton, a fan, a base, and a magnetic sealing strip. There are two bases, each fixed to the left and right sides inside the refrigeration chamber. A fan is placed inside each base. The air inlet is located on the surface of the cabinet and corresponds to the position of the base. There are two placement bases, each fixed to the left and right sides of the cabinet. Dehumidifying cotton is inserted inside each placement base. The magnetic sealing strip is fixed to the rear side of the cabinet door. The input end of the fan is electrically connected to the output end of the controller. Activating the two fans improves the efficiency of cold air circulation inside the cabinet, thus reducing power consumption and indirectly reducing carbon emissions. The dehumidifying cotton inside the placement base ensures the dryness of the incoming air, while the magnetic sealing strip effectively reduces cold air leakage, lowers the load on the refrigeration system, and improves overall energy efficiency.

[0010] Furthermore, the defogging unit includes a bracket, a linear motor, a moisture-absorbing cotton, Velcro tabs, and Velcro nut tabs. There are two linear motors, which are fixed to the left and right sides of the cabinet interior, respectively. The inner side of the linear motor actuator is connected to the end of the bracket. Velcro nut tabs are evenly distributed on the front side of the bracket, and Velcro tabs are attached to the back side of the moisture-absorbing cotton. The Velcro tabs and Velcro nut tabs are correspondingly attached. The input end of the linear motor is electrically connected to the output end of the controller. Activating the linear motor drives the moisture-absorbing cotton inside the bracket to quickly remove the fog from the surface of the cabinet door. This can effectively prevent energy loss caused by the temperature rise inside the cabinet due to opening and closing the cabinet door.

[0011] Furthermore, it also includes a support plate, a screw, and locking holes. There are two support plates, which are fixed on the left and right sides of the bottom surface of the shelf respectively. The screw hole in the middle of the support plate is threaded to the screw. The locking holes are evenly opened on the left and right sides inside the cabinet. By rotating the screw, it can be locked into the inside of the locking hole to adjust the height of the shelf, thereby meeting the storage needs of items of different sizes.

[0012] Furthermore, it also includes an insulation layer and a protective coating. The insulation layer is installed on the inner wall of the cabinet, and the protective coating is evenly applied to the surface of the cabinet. The insulation layer has excellent heat insulation performance and avoids the damage to the ozone layer caused by refrigerants in traditional refrigeration equipment, while the protective coating can avoid the pollution of the environment by volatile organic compounds in traditional paints.

[0013] Furthermore, it also includes a temperature sensor, which is installed on the left side of the cabinet. The output of the temperature sensor is electrically connected to the input of the controller. The temperature sensor works with the controller to automatically adjust the cooling power, avoiding frequent start-stop of the external compressor and further reducing energy waste.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This environmentally friendly three-door refrigerated display cabinet has the following advantages:

[0015] 1. By activating the two fans, the efficiency of cold air circulation inside the cabinet is improved, which can reduce power consumption and thus indirectly reduce carbon emissions. The dehumidifying cotton inside the cabinet ensures the dryness of the incoming air, while the magnetic sealing strip effectively reduces cold air leakage, reduces the load on the refrigeration system, and improves overall energy efficiency.

[0016] 2. By starting a linear motor to drive the moisture-absorbing cotton inside the bracket, the fog on the surface of the cabinet door is quickly removed. This can effectively prevent the energy loss caused by the temperature rise inside the cabinet due to opening and closing the cabinet door.

[0017] 3. The insulation layer used has superior heat insulation performance and avoids the damage to the ozone layer caused by refrigerants in traditional refrigeration equipment, while the protective coating can avoid the pollution of the environment by volatile organic compounds in traditional paints.
