Automatic temperature control and timing type electric oven is composed of furnace body, heater, thermostat, timer, converter switch, indicator lamp, baking tray, baking net, handle fork and so on.
1. Furnace
The furnace body of automatic temperature regulation and timing electric oven is composed of shell, internal chamber and furnace door. On the furnace on the right or below is the control room for thermostat, timer, switch switch and indicator. The shell is coated with anti-oxidation ammonia baking paint. The interior cavity surface is chrome-plated to improve the thermal reflectivity.
The furnace door of automatic temperature control timing electric oven is generally inlaid with high temperature resistant tempered glass as an observation window, which can observe the baking situation of food in the oven at any time. Steelened glass can withstand cold, in the process of using water generally will not break. But try to avoid water droplets falling on the toughened glass.
There is a elbow on each side of the furnace door, which extends into the furnace, and the end of the elbow is tightened by the pull spring. When the door is fully opened, the heavy moment of the door is slightly greater than the pull moment, and the door can be placed flat on the table. When lifting the furnace door, the furnace door heavy torque is getting smaller and smaller. When the furnace door heavy torque is less than the pull spring pull torque, the furnace door is automatically closed.
2. Heater
The heater of automatic temperature regulating timing electric baking furnace generally uses quartz glass pipe electric heating element or steel pipe electric heating element, quartz glass pipe electric heating element is made of spiral electric heating wire installed in milky white quartz glass pipe. The electric heating wire is kept in the center of the tube by the bracket, and the temperature of the quartz glass tube increases after energizing, which becomes a far-infrared radiation heat source. This electric heating element has a small heat capacity, fast heating up, high thermal efficiency, but easy to break.
3. Temperature regulator
The thermostat of automatic temperature adjustment and timing electric oven can use either flash-type thermostat or slow-type thermostat.
4. Switch switch
The conversion switch of automatic temperature regulation and timing electric oven is composed of camshaft, contact switch, base, bracket, etc. The camshaft is mounted on the bracket, with two cams, positioning blocks, transfer handles, etc.
5. Timer
The timer of the automatic temperature control timing type electric oven generally adopts the mechanical timer, which is composed of the walking system and the contact switch. Its structure principle is basically the same as the electric fan timer.
6. Typical circuit of visual temperature regulating and timing electric oven
The typical circuit of automatic temperature regulating timing electric oven is composed of upper heater, lower heater, thermostat, timer, converter switch, neon tube, current limiting resistance, power cord, power supply, plug, etc. In general, the upper and lower heaters are used in parallel.
