Description

Air duct circulation and heat conduction heating cabinet Technical Field The application relates to the technical field of heating cabinet manufacturing, in particular to an air duct circulation and heat conduction heating cabinet. Background The heating cabinet is one of the indispensable devices in the modern catering industry. In the baking industry, the heating cabinet is widely applied to bakeries, cake shops and various baking workshops, and has the main functions of keeping the temperature and taste of baked products, ensuring that fresh and discharged breads, cakes, desserts and the like can be displayed to customers in an optimal state, and being an ideal choice for fast food restaurants, convenience stores, supermarket cooked food areas and various dining places in the aspect of cooked food heat preservation. The display function of the heating cabinet is not neglected, and the transparent glass door design and internal illumination are not only convenient for customers to intuitively select foods, but also promote the overall dining experience. The conventional heating cabinets on the market mostly rely on a bottom heating plate to heat goods, but heat is excessively concentrated in a bottom area, so that the distribution of the heat of the goods in the vertical direction is extremely uneven, in order to solve the problem, some designs consider adding side heating plates, however, the design often compromises the attractiveness and the visual property of the goods display in the heating cabinet because the installation of side heating elements can block the sight or destroy the whole aesthetic layout, on the other hand, a hot air circulation system is adopted to heat the whole goods, although the heating uniformity can be improved theoretically, the back of the heating cabinet is usually designed to be open so as to facilitate the taking and placing of the goods by workers, so that once the cabinet door is opened, strong hot air can be directly blown to the workers in the hot air circulation process, and in addition, when the hot air is upwards transmitted and passes through each layer of the goods placing plates, the uniform and proper heating effect of each layer of goods can be difficult to be obtained due to the fact that the air speed is relatively high, and especially in the condition of relatively large spacing or dense placing of the goods is obviously heated. Disclosure of Invention The device provides an air duct circulation and heat conduction heating cabinet, and the specific implementation mode is as follows: an air duct circulation and heat conduction heating cabinet comprising: The cabinet body is provided with a heat preservation bin for placing goods above the cabinet body, a heating fan is additionally arranged below the cabinet body, and the output end of the heating fan is communicated with the heat preservation bin through a heat exchange cavity; The bottoms of the front end and the rear end of the heat preservation bin are respectively provided with an air return opening and an air outlet which are communicated with the heat exchange cavity; The front portion of the heat preservation bin is provided with the transparent cover, the back of the heat preservation bin is hinged with the opening and closing door plate, the opening and closing door plate is integrated with the flow equalizing box clamped in the heat preservation bin, the bottom of the flow equalizing box is communicated with the air outlet, a plurality of air blocking hole plates are vertically arranged below the inner side of the flow equalizing box, the flow equalizing box is arranged on one side of the heat preservation bin to be a grid mesh, the vertical uniformity and the horizontal uniformity of air circulation are improved through the grid mesh and the air blocking hole plates, the flow equalizing box is integrated on the opening and closing door plate, follow-up goods taking and placing are facilitated, and filter screens are additionally arranged at the positions of the air return opening and the air outlet. According to the technical scheme, the flow equalizing box is integrated on the opening and closing door plate, so that the operation flow of taking and placing follow-up goods is simplified, the working efficiency is greatly improved, once the opening and closing door plate is closed, the flow equalizing box inlet on the opening and closing door plate is automatically aligned with the air outlet of the heat exchange cavity, the air circulation path is optimized, the efficient operation of hot air circulation is ensured, the grid net of the flow equalizing box is of a uniform grid structure, and the uniformity of hot air introduction into the heat preservation bin can be improved. Preferably, a plurality of object placing plates for placing goods are vertically arranged in the heat preservation bin, and heating wires are arranged in each object placing plate. Based on the technical scheme, the heating
