Description

Technical Field

[0001] The invention relates to the technical field of freezers and refrigerators, and in particular to a commercial energy-saving refrigerator. Background Art

[0002] A freezer (also called a display cabinet) is a cabinet used to display products. It has different functions according to the occasion of use. There are two types of freezers: vertical freezers and horizontal freezers. For example, some fresh products that require low temperatures need to be cooled and kept fresh at low temperatures. The current horizontal freezers have two problems: First point: When supermarkets need to keep the interior of the cabinet at a low temperature, the surface of the glass cabinet door needs to be heated and defrosted. In the existing heating and defrosting structure, a set of heaters and air supply components are generally added directly inside the cabinet, and the heater heats the air and blows it toward the glass cabinet door. This defrosting structure requires an additional heating appliance to be added to the freezer, which increases the power consumption of the freezer. In addition, the hot air used to heat the glass cannot be discharged from the cabinet in time, which will affect the cabinet temperature, further increasing the energy consumption of the freezer.

[0003] Second point: When supermarket fresh produce is displayed in a horizontal freezer, the products in the freezer can only be observed through the glass door on the upper surface of the freezer. In this way, the observable field of view of the horizontal freezer is small, and can only be clearly observed within a range of about 2 meters in front of the freezer. The aisles between freezers in shopping malls are usually less than 1.5 meters. Therefore, to observe the products in the cabinet, you need to walk to the aisle of the cabinet to observe the items in the cabinet. It is impossible to observe from the adjacent aisle (one or two aisles apart), which brings inconvenience to customers.

[0004] Therefore, how to improve the energy saving of freezers and how to increase the observable range of freezers have become technical problems that need to be solved urgently in the industry. Summary of the invention

[0025] After adopting the above structure, the beneficial effects of the present invention are: 1. During the operation of the entire refrigeration system, the heat generated by the condenser is not directly discharged from the outside of the cabinet, but is blown to the inner surface of the glass door through the warm air supply duct for thermal defrosting, making use of the heat generated by the refrigeration process. There is no need to add a separate heater for hot air, making the entire freezer more energy-efficient. 2. Customers can observe the products inside the cabinet through the reflector surface in the passage outside the freezer, which is convenient for customers to observe the products inside the cabinet from a distance; 3. The reflector adopts a continuous flipping method, which can produce different inclination angles with the horizontal plane, and can be suitable for people of different heights to observe the products displayed in the cabinet from a distance; 4. The axis of the reflector's rotation is far away from the front and rear sides of the reflector, so that the reflector can have a larger swing amplitude at the position far away from both sides of the axis, thereby increasing the display range of the cabinet, and enabling the products on the front and rear sides of the cabinet to be reflected, so that the products can be displayed more comprehensively; 5. The axis of the reflector's rotation is far away from the front and rear sides of the reflector, so that the difference in the swing amplitude at each position of the reflector is smaller, so that the image of the product in the mirror on the front and rear sides of the reflector rolls slower, and the image of the reflector can be observed more clearly; 6. By turning the handle bolt, the lifting block, the adjusting slider and the fixing plate are all lifted and lowered relative to the adjusting guide rail, and the relative position of the lifting block and the lifting shaft is adjusted to achieve the adjustment of the swing limit position of the reflector, which can be applied to aisles with different spacings; 7. The reciprocating lifting follower wheel can drive the air outlet slot to swing around the hinge shaft, realizing the continuous back and forth swing of the air outlet slot in the air outlet direction, and can evenly sweep the surface of the product in the cabinet, making the temperature of each position in the cabinet more uniform; and the reciprocating swing of the air outlet slot and the reciprocating swing of the reflector share the same power, which reduces the power cost and makes the power structure simpler; 8. The hot gas on the surface of the glass door is discharged slowly and timely through the exhaust channel in the fixed strip and pumped to the surface of the reflector. On the one hand, it can defrost the surface of the reflector and prevent fog from accumulating on the reflector, which can ensure the clear surface of the reflector; on the other hand, it can prevent hot air from accumulating and sinking and staying inside the cabinet, reduce the impact of hot air on the temperature of the cabinet cavity, and reduce the load of the compressor; 9. The hot air heated by the glass door rises and flows into the heating inlet slot on the gradually rising glass door surface before being directly discharged. The impeller accelerates the hot air to be discharged to the outside of the cabinet, greatly reducing the impact of the hot air on the cabinet temperature. Compared with the existing hot air defrosting safe structure, it is more energy-saving.
