Description
Technical field
The utility model relates to ovens, and in particular to a kind of structure for reducing oven door surface temperature rise.
Background technique
Electric oven is a kind of equipment for processing wheaten food, such as bread, Egg Tarts, biscuit etc dessert.Electric oven currently on the market
The radiations heat energy baking food issued using heater element, the clean energy used have obtained the extensive use of Modern Family.
In recent years, European Union required to be increasingly stringenter to the surface temperature rise of the oven product of import.
The oven for possessing GS certification must satisfy EN60335-2-9A13/EK1 instruction.
In the past, according to b is annotated in table Z101 in EN 60335-2-9, when being limited to product structure or size, product cannot
When meeting the temperature limit of table Z101, the maximum temperaturerise of product is no more than 2 times of limit value in table, and in the 25MM of ventilation hole periphery
Exempt to survey.However, European Union gathered around in the requirement of new resolution (EU) 2017/1357 of its official's Web realease according on July 21st, 2017
The oven for having CE to authenticate also must satisfy EN60335-2-9A13/EK1 instruction, i.e. surface temperature rise presses single times of limit value, ventilation hole week
While being exempted without measurement.
206007029 U of Chinese utility model patent CN discloses " a kind of novel heat-insulation electric oven shell ", by roasting
The mode that intelligent radiator is added in case allows to be effectively reduced the temperature of oven, but this structure has the disadvantage in that
1, intelligent radiator design is complicated, higher cost,
2, it is easy to influence the internal temperature of oven, and influences the baking quality of food.
In conclusion need a kind of structure simple at present, heat can be effectively reduced from cooking cavity to oven door one
The structure of side conduction of velocity, and oven product outer surface is enable to reach GS/CE authentication requesting.
Utility model content
Technical problem to be solved in the utility model is that existing oven lacks simply and effectively reduction door body surface temperature
The problem of rising structure.
In order to solve the above-mentioned technical problem, technical solution used by the utility model is to provide a kind of reduction oven door
The structure of surface temperature rise, including the structure of French casement being rotatably mounted on toaster body, the structure of French casement is by outside extremely
It is interior include plastic cement doorframe and door inner panel,
The door inner panel is embedded with interior vitreum and forms inner insulating layer, and the plastic cement doorframe is embedded with outer vitreum and is formed outside
Thermal insulation layer is equipped with the air gap between the inner insulating layer and outer thermal insulation layer；
The top and bottom of the plastic cement doorframe offer convection holes respectively, two convection holes respectively with the air
Gap is connected to form convection channel.By this set, inner layer heat-insulation structure prevents the heat outflow of oven cooking cavity, and hinders
Most heat radiation is kept off and reflects, outer layer heat insulation structural ensures that oven door exterior surface temperature rise reaches CE/GS safety requirement, inside and outside
The upward free convection channel of hot gas is formed between thermal insulation layer, can partially be taken the heat between thermal insulation layer out of, be advantageously reduced roasting
The temperature of chamber door outer surface.
It in one embodiment, further include heat insulating strip, before the contact surface of the toaster body towards the door inner panel is equipped with
Surface frame, the heat insulating strip are arranged between the door inner panel and front plane frame.By this set, playing prevents heat from oven door
The effect that gap is overflowed.
In one embodiment, the material of the heat insulating strip is silica gel or glass material.By this set, make heat insulating strip
With good elasticity.
In one embodiment, the outside of the plastic cement doorframe is equipped with hardware door shell.By this set, play very well
Protective action.
In one embodiment, the material of the interior vitreum and outer vitreum be tempered glass, the interior vitreum and
The surface of outer vitreum is covered with LOW-E coating.By this set, interior glass 3,4 heat-proof quality of outer glass is made to reach best.
In one embodiment, reflecting plate is equipped between the plastic cement doorframe and door inner panel.By this set, can stop
Thermal convection and reflective portion heat radiation.
In one embodiment, the material of the door inner panel is hardware material.By this set, an inner panel can be made to have
Good heat insulation and preservation effect.
Detailed description of the invention
Fig. 1 is the appearance schematic diagram of the utility model.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings of the specification.
As shown in Figure 1, a kind of structure for reducing oven door surface temperature rise provided by the utility model, including rotationally
The structure of French casement being assemblied on toaster body 9, toaster body 9 is interior to have cooking cavity 11, and structure of French casement wraps from outside to inside
Plastic cement doorframe 1 and door inner panel 2 are included, since the plastic cement coefficient of heat conduction is lower, thermal insulation is good, so using plastic cement doorframe 1 as whole
The frame support of a glass door component.
Door inner panel 2 is embedded with interior vitreum 3 and forms inner insulating layer, plastic cement doorframe 1 be embedded with outer vitreum 4 formed it is outer heat-insulated
