According to the utility model, be provided with and prevent and/or detect dough to spill into the device for preparing outside the cylinder 50, so that cut off the electricity supply of different heating element.

In fact, as shown in Figure 5, amplified the zone C of Fig. 4, the indentation location of these cylinder 50 relative heating element heaters has been reserved at the edge 52 of the formation flange of described cylinder and the large space between the vertical wall.Under the situation of overflowing, exist a part of dough along flowing between at least one in this cylinder and described wall of direction F, heating element heater 40 and/or time heating element heater 42 in the contact, thus can cause emerging bigger cigarette, dough burned flame especially.

In order to limit described phenomenon, a plurality of schemes are described below, i.e. the purpose of this utility model.

One of them is to detect dough in this cylinder improper expansion in outside.Fig. 6 shows an embodiment, although wherein exist in the space 400 above the described cylinder, described dough still contacts described lid 4, and described space allows the top fermentation of dough 90 at described cylinder.

Therefore so improper expansion of described dough rises described lid, thereby described lid no longer contacts the periphery planar section 200 of main body 2.Under these circumstances, expectation stops the described heating element heater of electricity supply, because stopped up air circulation on the top of described electrical equipment, thereby can not cause good barbecue to bread, and may the described heating element heater of improper heating.

In order to coordinate to detect the running of described phenomenon and his electrical equipment of the visual control of user, can tolerate the temporary transient lid that rises described electrical equipment of user, and not cause the ongoing cycle to stop.Such operation can also allow to add composition in this cycle.Therefore, can set time-delay after detecting the described lid of rise, so that only postponing through just stopping the described ongoing cycle fully, the improper running of the electrical equipment that causes is overflowed in described time-delay corresponding to dough.

Heating element heater stop so stopping again ongoing program.Therefore can design with voice signal and/or optical signal and remind the user, described signal takes to be presented at the form of the error message on the screen 12, and it has shown the maloperation of overflowing relevant electrical equipment with dough.

Can implement the rise that different devices is used for detecting lid.The device that illustrates comprises the relay 80 that links to each other with the control circuit of heating element heater.According to the embodiment that illustrates, described relay is installed in the circuit that links to each other with microprocessor and allows microprocessor to stop the ongoing cycle by time-delay or non-time-delay so that the state relevant with opening of lid changes, therefore stop to the heating element heater supply, and point out the described reason that stops to the user, the opening of described lid corresponding to the information that passes to microprocessor.

Can use the device of other the described lid of detection, grating for example, weight sensor ....

Fig. 7 shows the device based on similar principles.Relay 250 has the contact 252 that activated by pendulous device 240, and described pendulous device 240 is mounted to around described axle 242 rotations, and described axle 242 is arranged in the vertical wall that defines preparation and barbecue space 30 one for example on the wall 32.Described pendulous device approximate horizontal and overflow dough 90 by contact and be rotated in a clockwise direction.

Can also conceive multiple structure: with pendulous device be placed on slightly described cylinder above, roughly at the plumb line place of described flange 52, perhaps be close to described flange 52 above, just shown in dotted line.In this situation, described pendulous device can also be mounted to the contact interaction by translation and relay.

Described pendulous device can also be arranged on described cylinder 50 flange 52 below, for example pendulous device 260, also are mounted to be centered around the axle rotation that described wall 32 places are provided with.Yet in the accompanying drawing situation, the rotation of pendulous device causes by cause group to drop to outside the cylinder because of spilling plane.Therefore, the rotation of pendulous device is carried out in the counterclockwise direction.Relay 270 therefore be arranged on pendulous device above, therefore described relay 270 has the contact 272 near the end of described pendulous device, described pendulous device is positioned at outside described preparation and the barbecue space.

In order to allow to detect on the whole periphery of described cylinder, evenly a plurality of pendulous devices have been installed in the compartment of terrain each other.Described pendulous device for example can also improve the detection of carrying out by the mechanical connection of horizon bar on the periphery of described cylinder.

Replacedly, described cylinder can be shaped to has breach, for example shown in Figure 8.In described structure, as noted earlier, described heating element heater 40,42 is along defining preparation and 3 of roasting in 4 vertical walls in space of described dough choose the road through.Therefore the connection of described heating element heater is passed through the 4th vertical wall and is realized, thereby has reserved important space 36 between described connection, and described space is preferred for detecting overflowing of dough.

Therefore, for possible unnecessary dough towards the zone that does not have heating element heater, described cylinder 540 and its edge 542 that constitutes flange have breach 544, it is positioned on the described space 36, thereby allowed unnecessary dough preferentially to flow along direction M, a pendulous device, for example pendulous device 260 therefore be arranged on described breach below, overflow thereby allow to detect, the mobile of unnecessary dough is to implement in the free space of heating element heater, perhaps directly do not contact with heating element heater at least when dough drops.

Best, the vertical wall that some limit described free space can be set, so that prevent dough flowing after heating element heater overflows.

The utility model has also related to the combination of the technical scheme that has just provided.The device that the utility model is not restricted to just describe, with and equivalent way.

In addition, the utility model also relates to the compensation device of protecting described heater, for example covers the baffle plate of the part of heater at least, and it can contact described dough when described dough overflows, thereby allows described dough to be offset described heater.

Fig. 9 shows the notion of another protection heating element heater, comprising: hide described heating element heater by the path of packing up dough when overflowing.The vertical wall in therefore described qualification preparation and barbecue space 30 is configured to be provided with a chamber, for example at the chamber 330 of the plumb line back of corresponding wall 320, described heating element heater 40 is arranged in the described chamber, so that the dough that overflows that will occur flows along described wall 320 by gravity, and can not contact described heating element heater.

Figure 10 shows another distortion of protection heater.Described electrical equipment 100 is depicted as not preparation and barbecue cylinder, and does not cover.According to described distortion, described preparation and barbecue space remain parallelepiped shape.On the contrary; described heater comprises 4 heating turbines; comprise the heating element heater that links to each other with ventilation unit respectively; described turbine is provided with preparation and barbecue space at each place, angle; thereby be subjected to being supported on vertical partition plate 110 protections on two sides and the diapire respectively; described two sides have formed described angle, and each dividing plate roughly extends on the whole height in described preparation and barbecue space.In order to allow air evenly be drained in the described barbecue space, each dividing plate is provided with the thin opening 112 of discharging air.These openings are enough narrow to hold the inner space of heating turbine so that prevent any may entering into of dough.

Described variant embodiment and the means for engaging as described above that heater is interrupted.

Other devices, temperature local measurement device for example, smoke detecting apparatus also can be used so that cut off electricity supply to heating element heater.

In addition, the utility model is not limited to heating element heater is set in preparation and barbecue in the space, as just described.In fact, dough overflows and has changed air and flow in the space of described cylinder, thereby stops up described air duct, perhaps forms the inlet of fresh air outside, particularly when rising described lid, as shown in Figure 6.This has caused the bad distribution of heat.

Up to the present, the bread that obtains better quality hardly may, and stop the ongoing cycle is rational, even it also is like this that heater is arranged on outside preparation and the barbecue space, described preparation links to each other with the described space of for example pipeline with the barbecue space, and does not have described heater and the actual danger that contacts that overflows dough.
