Abstract
The utility model relates to the technical field of electric ovens, in particular to a double-layer oven door frame. The double-layer oven door frame comprises a door frame and a door shaft, wherein the door frame is composed of inner layer heat-insulation glass and an outer heat-insulation layer, the inner layer heat-insulation glass and the outer heat-insulation layer are fixedly connected in parallel and at intervals through fixed connecting components, and a plurality of ventilating holes are further arranged on the fixed connecting components between the inner layer heat-insulation glassand the outer heat-insulation layer. After the structure is adopted, the double-layer oven door frame of the utility model can better prevent loss of heat energy, improve the efficiency of the ovens,and overcome the defects of high heat energy loss of existing single-layer oven door frame structures, thereby the double-layer oven door frame is characterized in that the structure is novel, the heat utilization efficiency of ovens can be improved.
Description
Technical field
The utility model relates to the electric oven technical field, refers in particular to a kind of double-deck baking box doorframe.
Background technology
Now, the oven door mount structure generally adopts one deck glass structure, and thermal losses is than higher like this, therefore, how to improve the oven door mount structure with improve energy utilization rate, cutting down the consumption of energy to become has technical problem to be solved.
Summary of the invention
The purpose of this utility model is exactly at the deficiencies in the prior art part and a kind of novel structure that provides, the doorframe that has reduced the double-deck baking box of thermal losses.
For achieving the above object, the utility model includes doorframe and door-hinge, described doorframe is made of internal layer heat resistant glass and outer refractory layer, described internal layer heat resistant glass is fixedlyed connected by the fixed connecting piece parallel interval with outer refractory layer, the internal layer heat resistant glass and outside also have several air-vents on the fixed connecting piece between the refractory layer.
Described outer refractory layer is by the heat resistant glass with several apertures or heat resistant plastice is made or a wire netting is made.
Described fixed connecting piece can be the intermediate plate of two M shapes, upper clip is folded in the top of internal layer heat resistant glass and outer refractory layer, lower clamping piece is folded in the top of internal layer heat resistant glass and outer refractory layer, and has air-vent on upper clip, also has air-vent on lower clamping piece.
Described fixed connecting piece can be the intermediate plate of two M shapes, and left intermediate plate is folded in the left side of internal layer heat resistant glass and outer refractory layer, and right clamping piece is folded in the right side of internal layer heat resistant glass and outer refractory layer.
The intermediate plate of described M shape is made by metal or nonmetallic materials.
The part that contacts with fixed connecting piece on the described outer refractory layer has several contact points.
Described internal layer heat resistant glass and outer refractory layer are all made by glass material, and this glass material can be two-way mirror or tempered glass.
After adopting said structure, double-deck baking box doorframe of the present utility model can prevent heat energy loss better, has improved the efficient of baking box, has overcome the high deficiency of heat energy loss of existing single oven doorframe structure.Therefore, the utlity model has novel structure, can improve the characteristics of baking box heat utilization efficiency.

The specific embodiment
As Fig. 1-5, the utility model includes doorframe and door-hinge, described doorframe is made of internal layer heat resistant glass 2 and outer refractory layer 1, described internal layer heat resistant glass 2 is fixedlyed connected by fixed connecting piece 3 parallel interval with outer refractory layer 1, internal layer heat resistant glass 2 and outside also have several air-vents on the fixed connecting piece 3 between the refractory layer 1.
As shown in Figure 5, described outer refractory layer 1 is by the heat resistant glass with several apertures or heat resistant plastice is made or a wire netting is made.
Shown in Fig. 1-2, described fixed connecting piece 3 can be the intermediate plate of two M shapes, upper clip 31 is folded in the top of internal layer heat resistant glass 2 and outer refractory layer 1, lower clamping piece 32 is folded in the top of internal layer heat resistant glass 2 and outer refractory layer 1, and on upper clip 31, have air-vent 311, on lower clamping piece 32, also have air-vent 321.The intermediate plate of described M shape is made by metal or nonmetallic materials.
As shown in Figure 4, described fixed connecting piece 3 can be the intermediate plate of two M shapes, and left intermediate plate 33 is folded in the left side of internal layer heat resistant glass 2 and outer refractory layer 1, and right clamping piece is folded in the right side of internal layer heat resistant glass 2 and outer refractory layer 1.
As shown in Figure 3, the part that contacts with fixed connecting piece 3 on the described outer refractory layer 1 has several contact points 11.
Described internal layer heat resistant glass 2 and outer refractory layer 1 are all made by glass material, and this glass material can be two-way mirror or tempered glass.
As shown in Figure 1, on doorframe, also can be provided with handle 4.
During use, heat energy in the baking box is earlier by internal layer heat resistant glass 2 barriers, the heat energy that sees through internal layer heat resistant glass 2 is also lived by barrier in the outer refractory layer 1 once more, therefore, its effect of heat insulation will improve much than individual layer doorframe efficient, like this, just can prevent heat energy loss better, improve the efficient of baking box, overcome the high deficiency of heat energy loss of existing single oven doorframe structure.Therefore, the utlity model has novel structure, can improve the characteristics of baking box heat utilization efficiency.
