Description

Technical Field

[0001] This utility model belongs to the field of shelf technology, specifically, it relates to a heated shelf for a display cabinet. Background Technology

[0002] Currently, heated display shelves in commercial display cases generally use built-in resistance heating wires or flat-plate heating elements for heating. This traditional heating structure has the following technical drawbacks:

[0003] Firstly, traditional shelf structures lack space adjustment capabilities and cannot accommodate the mixed storage needs of canned and bottled beverages of different sizes, resulting in excessively large or dense display spacing, which reduces space utilization and weakens the visual display effect.

[0004] Secondly, due to the limitations of heat conduction of linear heating wires and the limited contact area of ​​flat plate heaters, temperature gradients are easily generated on the surface of the shelf. Actual measurements show that the temperature difference in the edge area can reach 8-12℃, causing uneven heating of beverages and affecting their taste and quality.

[0005] Third, the heating element is directly exposed to the cabinet environment, resulting in intense heat exchange with the outside cold air, which leads to serious heat loss and high operating energy consumption;

[0006] Fourth, the independent electric heating system is not linked with the thermal cycle of the refrigeration unit, and the waste heat of the 50-70℃ high-temperature refrigerant discharged by the compressor is not effectively recovered and utilized, resulting in significant energy waste.

[0007] The aforementioned technical shortcomings severely restrict the practical application value of heating display equipment in supermarkets, convenience stores, and other scenarios. In view of this, this utility model is proposed. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0044] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0045] like Figures 1 to 3 As shown, the present invention provides a display cabinet heating shelf, including a heating shelf 1. The heating shelf 1 is made of a heat-conducting material (such as aluminum alloy sheet), and its surface is coated with a corrosion-resistant ceramic coating. The heating surface has an elongated heating cavity 3 that extends along the length of the shelf.

[0046] Furthermore, at least one adjustable shelf 2 is detachably provided on the shelf surface of the heating layer 1. Specifically, the adjustable shelf 2 includes a bottom wall 21 connected to the shelf surface of the heating layer 1, and two side walls 22 extending perpendicular to the shelf surface of the heating layer 1 and fixedly connected to the bottom wall 21 at the bottom.

[0047] In a preferred embodiment, the bottom wall 21 and side wall 22 of the adjustable shelf 2 are integrally formed using a heat-conducting plate (such as an aluminum alloy plate), or they can be formed by welding, bonding or other methods.

[0048] In a preferred embodiment, the bottom surface of the adjustable shelf 2 is provided with a magnetic strip, which is magnetically attracted to the shelf surface of the heating plate 1. Multiple shelves can be freely arranged along the length of the heating plate 1, and the spacing between adjacent shelves can be adjusted by the magnetic strip. Optionally, a sliding groove and a guide rail can also be provided between the heating plate 1 and the adjustable shelf 2, and the shelf can be adjusted and locked by sliding cooperation between the sliding groove and the guide rail.

[0049] In a preferred embodiment, the contact surface between the heating plate 1 and the adjustable shelf 2 is coated with a thermally conductive silicone grease layer, and a graphene thermally conductive film is embedded in the bottom wall 21 of the shelf, which effectively enhances the thermal conductivity.

[0050] The adjustable shelf 2 adopts a modular design. Its bottom wall 21 and side wall 22 form a detachable support unit that supports multi-dimensional position adjustment. It can accommodate containers and items of various sizes, effectively improving the space utilization rate inside the display cabinet while forming a regular three-dimensional display array. At the same time, the bottom wall 21 and side wall 22 of the adjustable shelf 2 can effectively conduct heat, increase the heating area, and improve the heating efficiency of the items inside.

[0051] In a preferred embodiment, the surface of the heating chamber 3 is covered with a removable cover plate 5. The cover plate 5 is fixed to the shelf body by a snap-fit ​​structure or countersunk screws, and the seams are filled with high-temperature resistant silicone sealing strips to achieve IP54-level leak-proof performance. The heating component 4 is disposed inside the heating chamber 3, and the surface of the heating chamber 3 is covered with the cover plate 5 to reduce heat loss and achieve high efficiency and energy saving.

[0052] In a preferred embodiment, the heating assembly 4 includes a medium conduit 41 and an array of heat exchange fins 42 arranged outside the medium conduit 41. The heat exchange fins 42 are preferably finned aluminum heat exchange fins. The heating medium heats the items (such as beverages) on the heating plate 1 through the medium conduit 41 and the heat exchange fins 42, and the heat exchange fins 42 effectively improve the heat transfer effect.

[0053] In a preferred embodiment, the medium pipeline 41 is connected to the high-temperature refrigerant circulation pipeline of the refrigeration unit.

[0054] For example, the medium pipeline 41 is made of Φ8mm copper pipe, arranged in a serpentine pattern, and connected to the high-temperature refrigerant circulation pipeline of the refrigeration unit through three-way valves at both ends. The refrigerant flow rate is set to 0.5-1.2m / s.

[0055] The refrigerant flow control logic is as follows:

[0056] When the compressor of the refrigeration unit starts, the high-temperature refrigerant (temperature 50-70℃) is diverted to the medium pipeline 41 through the three-way valve, flows through the serpentine copper tube and returns to the condenser of the refrigeration unit;

[0057] The refrigerant flow rate is dynamically adjusted by a PID controller to keep the surface temperature of the heating plate 1 stable within the set range (e.g., 40±1.5℃).

[0058] When the refrigeration unit is running, the high-temperature refrigerant flows into the medium pipeline 41 and transfers heat to the heating plate 1 through the finned heat exchanger 42;

[0059] Heat is conducted through the thermally conductive silicone grease layer to the adjustable shelf 2, and the items are heated in contact with the shelf which is positioned by magnetic attraction or sliding rail;

[0060] After the refrigerant waste heat is recovered, it is returned to the refrigeration unit's circulation system, forming a closed-loop energy-saving heat exchange.

[0061] Heating component 4 is linked with the refrigeration unit's thermal cycle to recover and utilize the waste heat from the refrigerant discharged by the compressor, thus saving energy and protecting the environment.
