Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the present invention is described in detail.Wherein, accompanying drawing only for exemplary illustration, expression be only schematic diagram, but not pictorial diagram, can not be interpreted as the restriction to this patent; In order to embodiment of the present utility model is described better, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; For a person skilled in the art, in accompanying drawing, some known features and explanation thereof may be omitted is understandable.
Embodiment 1
As depicted in figs. 1 and 2, the utility model provides a kind of refrigerating thermal-insulation equipment with exhaust structure, comprises insulation shell 1.The casing of described refrigerating thermal-insulation equipment and door body are formed with shell 2 and inner bag 3 respectively, and shell 2 and inner bag 3 form described insulation shell 1, and described insulation shell 1 hollow is also built-in with foam chamber 4.As shown in Figure 1, the side of the insulation shell 1 of the present embodiment is provided with an exhaust passage 5, concrete, described exhaust passage 5 is formed with the air inlet 51 connecting foam chamber 4 and the exhaust outlet 52 connecting the external world, and the volume space of exhaust passage 5 reduces gradually from air inlet 51 to exhaust outlet 52.When foamed material flows to exhaust passage 5, along with the volume space of exhaust passage 5 reduces gradually, foamed material extrudes cooling gradually and becomes sealing, and foamed material stopped flowing before spilling, avoided the spilling of foamed material.This structure is beneficial to discharges air in foaming process, ensures the heat insulation effect of refrigerating thermal-insulation equipment.
Embodiment 2
As shown in Figures 2 to 4, the present embodiment provides a kind of refrigerating thermal-insulation equipment with exhaust structure, comprise insulation shell 1, the casing of described refrigerating thermal-insulation equipment and door body are formed with shell 2 and inner bag 3 respectively, shell 2 and inner bag 3 form described insulation shell 1, and described insulation shell 1 hollow is also built-in with foam chamber 4.Described insulation shell 1 is provided with several exhaust passages 5, each exhaust passage 5 is formed with the air inlet 51 connecting foam chamber 4 and the exhaust outlet 52 connecting the external world, and the volume space of exhaust passage 5 reduces gradually from air inlet 51 to exhaust outlet 52.When foamed material flows to exhaust passage 5, along with the volume space of exhaust passage 5 reduces gradually, foamed material extrudes cooling gradually and becomes sealing, and foamed material stopped flowing before spilling.This structure is beneficial to discharges air in foaming process, ensures the heat insulation effect of refrigerating thermal-insulation equipment.
Further, as shown in Figure 2, described exhaust passage 5 is arranged on the shell face, downside of insulation shell 1, has certain disguise, is not easy to make exhaust passage 5 be exposed to people within sweep of the eye, makes the overall better appearance of insulation shell 1.
As shown in Figs. 4-6, the shell face of insulation shell 1 is formed with three boss 6, it is interior and consistent with the protrusion direction of boss 6 that exhaust passage 5 is formed in boss 6, five exhaust passages 5 are formed in each boss 6, five exhaust passages 5 are uniformly distributed in boss, and the ventilation direction of described five exhaust passages 5 is consistent with the protrusion direction of boss 6.Exhaust passage 5 is formed in boss 6, the length of exhaust passage 5 is extended, and be no longer only confined to the sidewall thickness of insulation shell 1, the foamed material that the exhaust passage 5 possessing certain length is more conducive in exhaust passage 5 dispels the heat, and then be cooled to sealing fast, avoid the spilling of foamed material, be beneficial in foamed material foaming process simultaneously and evenly discharge air.
Further, if boss 6 outwardly protrudes, will affect the outward appearance of insulation shell 1, therefore preferably, in the present embodiment, each boss 6 all protrudes towards described foam chamber 4 direction.As shown in Figs. 7-9, arranging of boss 6 can cause the uneven of insulation shell 1 wall thickness, print of shrinking can be formed in injection moulding process, shrink print is formed directly on insulation shell 1 can affect product appearance, therefore, on the shell face, downside of described insulation shell 1, the position of corresponding exhaust passage 5 exhaust outlet 52 is formed with recess 7 further, a corresponding recess 7 of boss 6, be equivalent to position print of shrinking being transferred to recess 7, because recess 7 is subject to blocking of the downside shell face diapire of insulation shell 1, shrinking print just can not be directly in sight, also just there is certain disguise.An exhaust structure is formed by 5, one, five exhaust passages boss 6 and a recess 7.
As shown in Figures 2 to 4, the quantity of boss 6 is several, in the present embodiment, the quantity of boss 6 is three, several boss 6 described arrange on the shell face, downside of insulation shell 1, each boss 6 is all formed with several exhaust passages 5, is several and is distributed in multiple positions of insulation shell 1 due to exhaust passage 5, and thus in foaming process, the gas be more conducive in foam chamber 4 is discharged fast.
Further, as shown in FIG. 5 and 6, insulation shell 1 is formed with the groove 8 towards foam chamber 4 direction depression, described three boss 6 are arranged in groove 8, namely three described exhaust structures are formed in a groove 8, groove 8 decreases exhaust structure and appears at chance in visual line of sight, makes exhaust structure have certain disguise, makes insulation shell 1 more attractive in appearance.
Concrete, as shown in Figures 2 to 4, groove 8 is formed with five reinforcements 9, each reinforcement 9 is separately positioned between each described recess 7, three exhaust structure lattices are come, have an exhaust structure at the most between every two reinforcements 9, this reinforcement 9 also has the effect strengthening shell face, place, exhaust passage intensity.
More specifically, exhaust passage 5 is plastics injection moulding integrated molding with the shell face of the insulation shell 1 at its place.And each exhaust passage 5 is halfpace shape, convenient manufacture is shaping.
