The invention comprises directly filling heat into the pre-installed box body of the refrigerator cabinet by using heating equipment; directly filling heat into the refrigerator from the injection port into the refrigerator cabinet pre-installed box body through heating equipment; the heating type equipment is a hot air filling machine. According to the invention, the hot air equipment is used for filling heat into the box body to preheat parts in the box. Compared with the prior art, the invention has the advantages that firstly, the in-box heat perfusion has better preheating effect compared with the preheating outside the drying tunnel, thereby being beneficial to improving the quality problems of back debonding, air bubbles and the like, secondly, the in-box heat perfusion can replace the traditional drying tunnel preheating mode, realizing energy saving, and finally, the foaming crust is thinner through the in-box heat perfusion, thereby being beneficial to reducing the density of the foaming core and saving the product cost.
Description
Technical Field
The invention belongs to the technical field of preheating of a foaming box body of a refrigerator cabinet, and particularly relates to a hot filling foaming process for the refrigerator cabinet.
Background
In order to control the foaming quality of the refrigerator cabinet and prevent quality problems such as debonding, the heating mode of the refrigerator cabinet is a drying channel heating mode, the heating principle of the mode is to establish a surrounding room, the temperature of the surrounding room is improved through fan heating, and the high-ring temperature in the surrounding room heats the refrigerator cabinet. The heating mode is heating from outside to inside, the internal temperature is low, the temperature drops quickly after the box body goes out of the enclosed room, and the heating effect is achieved; under extremely cold conditions in winter, the preheating effect still can not reach expectation, and the debonding problem of foaming back is obvious, and the debonding can appear in the curb plate under the severe condition. Secondly, the preheating drying tunnel belongs to high-energy-consumption equipment, and the energy consumption is high. Finally, the preheating outside the box is not beneficial to the reaction and flow distribution of the foaming material, so that more foaming bubbles, thick crusts and uneven density distribution are caused, and the comprehensive cost of the product is increased.
