Detailed Description
Embodiments of the present invention are further described below with reference to the accompanying drawings.
Referring to fig. 1 to 3, a heat insulation structure for an oven includes an outer shell top plate 1, an inner shell top plate 2, an inner shell 3, an outer shell 4, a heat insulation layer 5, and a connecting bolt and nut 6; the top plate 1 and the top plate 2 of the inner shell are planar plate structures, the periphery of the top of the inner shell 3 is outwards bent to form a 90-degree bending structure 31, the top plate 2 of the inner shell is covered on the top of the inner shell 3, and the inner shell is horizontally erected through the bending structure 31 of the inner shell 3; the heat preservation layer 5 is horizontally paved on the inner shell top plate 2, and the outer shell top plate 1 is horizontally paved on the upper end surface of the heat preservation layer 5; the top of shell 4 inwards buckle around and be 90 bending structure 41, inner shell 3 set up in shell 4, just the upper end of inner shell 3 be higher than the upper end of shell 4, bending structure 31 of inner shell 3 with bending structure 41 of shell 4 between be equipped with heat preservation 5, the inside wall of shell 4 with the lateral wall of inner shell 3 between fill have heat preservation 5, connecting bolt nut 6 run through outer shell roof 1, inner shell roof 2, bending structure 31 and heat preservation 5 of inner shell 3 of inner shell 4 and fixed.
The inner shell 3 is not contacted with the outer shell 4, and the inner shell 3 is hung inside the oven.
Because inner shell 3 and inner shell roof 2 all can receive the high temperature heating in the stove, the buckling structure 31 of inner shell 3 on be equipped with bolt trompil 32, the internal diameter of bolt trompil 32 be greater than the external diameter of connecting bolt nut 6 more, can avoid the bolt to receive the heating of these two high temperature parts like this, make the thermal bridge connection disconnection of interior external surface, the shell 4 is less with the heating of shell roof 1.
The edges of the outer ends of the inner shell 3 and the inner shell top plate 2 are respectively positioned on the inner side of the edge of the outer end of the heat preservation layer 5 and are hidden in the heat preservation cotton 5, so that heat dissipation is reduced.
The bottom of the inner shell 3 is outwards bent to form a 90-degree bottom bending structure 33, the bottom bending structure 33 of the inner shell 3 is located above the bottom 42 of the furnace body of the outer shell 4, and the lower part of the heat preservation layer 5 is supported by the bottom bending structure 33 of the inner shell 3 at the bottom of the oven.
The heat preservation layer 5 is clamped between the inner shell 3 and the outer shell 4, and the bottom bending structure 33 of the inner shell 3 is at a certain distance from the inner surface of the outer shell 4 and cannot contact the outer shell 4, so that heat cannot be conducted to the outer shell 4 through the inner shell 3, and the heat preservation effect is improved. The bottom bending structure 33 of the inner shell 3 is at a distance from the furnace bottom 42. Is not in contact with the furnace bottom 42. To prevent the furnace bottom 42 from transferring heat outwards, the furnace bottom 42 may be placed on top of the insulating layer 5.
When the temperature inside the oven starts rising, the inner casing 3 and the inner casing top plate 2 are heated up. When heat is conducted to the bolt, the bolt is not affected by the high-temperature component because the bolt is not in contact with the high-temperature component and keeps a certain distance. So that the side surfaces of the housing top plate 1 and the housing 4 connected at the upper and lower ends of the bolts are not heated. The bottom of the inner shell 3 is not in contact with the outer shell 4 and the bottom 42 of the furnace body, and there is no thermal bridge connection, and the heat loss path in the furnace is blocked.
The heat preservation layer 5 is clamped and fixed between the inner shell and the outer shell, and an additional connecting piece is not needed to pass through and fix, so that the addition of a thermal bridge connection is avoided. The heat preservation effect depends on the selection of the heat preservation layer 5, the lower the heat conductivity of the heat preservation layer 5 is, the better the heat preservation effect is, and the thinner the furnace body thickness can be.
