Description
Technical field
The utility model relates to a kind of open and close door of electric oven.
Background technology
Electric oven is a kind ofly to be converted into heat energy toasts processing to food kitchen electric equipment by consumed power.Traditional its primary structure of family expenses electric oven comprises the casing that surrounds a heating chamber, be used to pick and place the be communicated with heating chamber that is heated food and extraneous open and close door, be arranged in heater block and the control that heater block is controlled and regulated in the heating chamber and regulate parts.The family expenses electric oven of two or more heating chambers has also appearred having at present.Existing electric oven is when baking food heats, temperature under the normal temperature laboratory state in its heating chamber can reach about 240 ℃, the temperature of the outer surface of the easiest open and close door that touches of consumer (also being called " cold surface ") can be above 100 ℃, peak even can be above 150 ℃, have the potential safety hazard of scalding the people, European Union is fermenting this safety problem is being taked mandatory requirement.But because open and close door generally adopts the single-glass manufacturing, want to reduce the temperature of cold surface, difficult technically enforcement perhaps also do not implemented because the solution cost is high.There is the too high defective of surface temperature in therefore existing electric oven, has bigger potential safety hazard, can't reach the new safety standard of preparing enforcement in the future.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of good heat-insulation effect, cold surface temperature low, open that convenience, safety, installation are quick, easy, the open and close door of reliable electric oven.
The technical scheme that the utility model adopted is: the utility model comprises first holder, second holder, handle, door-plate, rotating shaft, described first holder, described second holder is fixedly connected with two opposed side edges of described door-plate respectively, described first holder rotates with the casing of electric oven by described rotating shaft and is connected, described first holder, described second holder is the identical section bar of each shape of cross section, described first holder is provided with axis hole and at least two first clamping parts, described second holder is provided with at least two second clamping parts, described axis hole and described rotating shaft are suitable, described first clamping part is oppositely arranged with described second clamping part and will grips by consistent described door-plate with its quantity, leaves the space between the adjacent described door-plate.
Relative shifting to install between the most inboard described first clamping part of described first holder and other described first clamping part.
Described axis hole is positioned at the corresponding position of the most inboard described first clamping part.
The opening of described first clamping part, described second clamping part is equipped with certain gradient, and described first clamping part, described second clamping part rely on gradient that described door-plate is clamped.
Space between the adjacent described door-plate communicates with the external world.
Described second holder has two and lay respectively at the two ends of a side of the described door-plate of its clamping, and the space between the adjacent described door-plate between two described second holders communicates with the external world.
Described handle is between two described second holders, and described handle is clamped and fastened on the side of outermost described door-plate.Perhaps, described handle is fixedly connected on two described second holders.
Described door-plate adopts the glass manufacturing.
Described door-plate is flat board or arc.
The beneficial effects of the utility model are: because first holder described in the utility model, described second holder is the identical section bar of each shape of cross section, described first holder is provided with axis hole and at least two first clamping parts, described second holder is provided with at least two second clamping parts, described axis hole and described rotating shaft are suitable, described first clamping part is oppositely arranged with described second clamping part and will grips by consistent described door-plate with its quantity, leave the space between the adjacent described door-plate, the utility model adopts two-layer at least described door-plate to carry out multistage heat insulation processing, help reducing the surface temperature of the described door-plate of outermost layer, space between the adjacent described door-plate also helps further reducing the temperature of cold surface, prevent to scald, improve security, the employing section bar grips described door-plate and matches with described rotating shaft, make that the installation of whole open and close door is quick, easy, reliably, but the described door-plate of Fast Installation multilayer, the production efficiency height, can guarantee simultaneously the normal opening and closing of open and close door, easy to use, so the utility model good heat-insulation effect, the cold surface temperature is low, it is convenient to open, safety, install fast, easy, reliably;
Because relative shifting to install between the most inboard described first clamping part of first holder described in the utility model and other described first clamping part, make that the residing section bar of described first clamping part position width is less, avoid since adopt the described door-plate of multilayer to make open and close door thickness increase to bring may produce the drawback of interfering with casing, make the maximum opening angle of open and close door not be subjected to the constraint of casing simultaneously as far as possible, having solved open and close door embeds under the situation of casing, owing to adopt the multilayer door-plate to cause the thickness of open and close door to increase the restricted problem of bringing of opening angle, so the utility model is opened free, opening angle is big, conveniently picks and places food;
Because axis hole described in the utility model is positioned at the corresponding position of the most inboard described first clamping part, make the radius of turn minimum at described axis hole position, avoid to produce the drawback of interfering with casing because radius of turn is excessive, increase the opening angle of open and close door to greatest extent, so the utility model is opened convenient, opening angle is big, conveniently picks and places food;
Because the opening of first clamping part described in the utility model, described second clamping part is equipped with certain gradient, described first clamping part, described second clamping part rely on gradient that described door-plate is clamped, the utility model has utilized the elasticity of section bar itself to rely on gradient described door-plate can be clamped, can not be screwed, so the assembling of the utility model door-plate is fast and reliable, the efficient height;
Because the space between the adjacent described door-plate of the utility model communicates with the external world, hot-air in each space can rely on the variation of autologous density to flow to the external world automatically, thereby heat is taken away, and has further reduced the temperature of cold surface, so the utility model good heat dissipation effect, the cold surface temperature is low;
Because second holder described in the utility model has two and lay respectively at the two ends of a side of the described door-plate of its clamping, space between the adjacent described door-plate between two described second holders communicates with the external world, the air that has further strengthened in the space between the adjacent described door-plate flows, more help taking away heat, reduce temperature, so the utility model good heat dissipation effect, the cold surface temperature is low.
