Rate is set as 250W.
When each heat block is directly connected to 220V alternating current, then the surface resistance of heating element 16 is 193.6 Ω/sq.
When each heat block connects 36V power supply, as shown in fig. 6, the roasting plant can also work normally, heating element 16
Surface resistance be 20.7 Ω/sq.
Heating element is in addition to also can be used two pieces of heating using other than the form of electrode is respectively set in one piece of heat block both ends
The form that block overlaps is constituted, as shown in fig. 7, can further improve heating efficiency.
When using two pieces of heat blocks, three electrodes of upper, middle and lower are equipped with, each electrode runs through heat block from left to right, wherein
Upper/lower electrode is electrically connected with two pieces of heat block one end, and is connected to positive pole, target and two pieces by control panel 9 respectively
Heat block has good electrical connection, powers on cathode and is grounded.
Temperature sensor 15 is embedded in heat block target, and 15 lead of temperature sensor is drawn along target, with
Control panel 9 is connected.Meanwhile each heating element 16 is controlled by control panel 9, independently selects operation one of or several by user
Block heating.
Embodiment three
In an advantageous embodiment, roasting plant is additionally provided with steam unit, makes it have steam function, is selected by function
Selecting knob 5 may be selected steam mode.
As shown in Figures 2 and 3, mating for placing in the side of the roasting plant of the present embodiment there are a water box slot
Water box 18, the water box 18 are detachable, and are equipped with handle, facilitate pick-and-place, and the filler of water box 18 can open at any time, run in equipment
Any stage can carry out at any time plus water operation.Water box 18 are mating to be equipped with water pump 19 and water level sensor 20,19 He of water pump
Water level sensor 20 is connected with control panel 9 respectively.Water pump 19 is used to export in the water in water box 18, and carrying capacity passes through control plane
Plate 9 controls, and then adjustable steam rate.Water level sensor 20 is for monitoring water level conditions in water box 18, and by water amount information
Control panel 9 is fed back to, as water level is alarmed lower than preset water level control panel 9 by buzzer 12.
19 delivery outlet of water pump is connected by water pipe 21 with the water filling port 22 on the upside of 1 side wall of cabinet, and water filling port can be one
Or it is multiple, when being multiple, it is horizontally-arranged to line up one.
After steam mode is opened, the heating part of roasting plant works, and thermal element 16 to be added reaches (such as 100 DEG C of certain temperature
More than) after, control panel 9 controls water pump 19 and works, and water is delivered to water filling port 22, the waterfront economy mouth of a river 22 is sliding along 1 inner wall of cabinet
It falls, since 1 inner wall temperature of cabinet is more than 100 DEG C, water droplet gasifies during sliding along cabinet wall as water vapour, steaming food
Material.
Preferably, identical water filling port 22 can also be equipped at the opposing sidewalls of roasting plant, water pump 19 passes through water pipe 21
