Abstract
A dual cavity electric heating oven comprises an oven, an oven gate, two cavities divided by a barricade, U type heater on each bottom plate of the two cavities, temperature sensors on back plates of two cavities, fans loaded inside the ventilation holes, with the heater, temperature sensor connecting with the outside power and control circuit. Through automatic regulating the temperature of two cavities, it can realize adjustable coupling control of two cavities and dual control of temperature rising and dropping, with small power, size, and light weight, low cost and convenient maintenance.
Description
Technical field
The invention belongs to a kind of electric heater unit, particularly a kind of double-chamber electric heating furnace that is used for education experiment.
Background technology
The conventional electric heating stove is generally single cavity, and heater is only arranged, and can't realize heating up and dual control of lowering the temperature and the relevant control of coupling, can not satisfy the requirement of experimental teaching.
Summary of the invention
In order to solve the problem of above-mentioned existence, the invention provides a kind of double-chamber electric heating furnace, it is to have two cavitys, can realize heating up and the dual control of lowering the temperature and dual chamber between a kind of heater of coupling control.
Of the present invention kind of double-chamber electric heating furnace comprises body of heater, fire door, be provided with a dividing plate in the centre of body of heater, make electric furnace form two cavitys, on the base plate of two cavitys, be respectively equipped with the inverted U heater, be respectively equipped with temperature sensor, fan and air vent on the backboard of two cavitys, fan is installed in the air vent; Its heater, temperature sensor link to each other with the power supply and the control circuit of outside, finish control by control circuit.Have perforate on the dividing plate of this heating furnace, on side plate, be provided with a connecting rod, be respectively equipped with baffle plate in dividing plate perforate both sides, baffle plate is fixed on the connecting rod by screw, can rotate with connecting rod, connecting rod is connected on the knob of body of heater outside by lever in the body of heater side plate or motor, comes drivening rod to rotate by manual or motor.Control circuit comprises heater, temperature sensor, fan and instrument, solid-state relay, and U type heater links to each other with power supply by solid-state relay, and temperature sensor is connected on the instrument, controls this heating work process by instrument.
Advantage of the present invention is the temperature that can regulate two cavitys automatically, realize adjustable coupling control between intensification and dual control of lowering the temperature and dual chamber, and single-machine capacity is little, and volume is little, and is in light weight, and price is low, and is easy to maintenance.

The specific embodiment
Further narrate content of the present invention below in conjunction with drawings and Examples;
Frame for movement of the present invention as shown in Figure 1 and Figure 2, comprise body of heater, fire door 10, be provided with a dividing plate 2 in the centre of body of heater, form two cavitys, be respectively equipped with inverted U heater 3 on the base plate 1 of two cavitys, be respectively equipped with temperature sensor, fan B11 and air vent on the backboard 9 of two cavitys, fan B11 is installed in the air vent, its heater, temperature sensor link to each other with the power supply and the control circuit of outside, control by control circuit.Have perforate on the dividing plate 2, on side plate 6, be provided with a connecting rod 7, be respectively equipped with baffle plate 4 in dividing plate 2 perforate both sides, baffle plate 4 is fixed on the connecting rod 7 by screw, can rotate with connecting rod 7, connecting rod 7 is by lever or be connected by the motor in the body of heater on the knob of body of heater outside, drives its rotation by manual or motor.Control circuit comprises U type heater 3, temperature sensor 8, fan A5 and instrument 12, solid-state relay K1, K2, and U type heater 3 links to each other with power supply by solid-state relay, and temperature sensor 8 is connected on the instrument 12, by instrument 12 these heating work processes of control.
The course of work of the present invention is: set the temperature in two chambeies on instrument 12, connect power supply, make 3 heating of U type heater, temperature in the chamber is transferred on the instrument 12 by temperature sensor 8, by the size of instrument 12 displays temperatures, instrument 12 is according to the work of temperature control needs control solid-state relay, if temperature reaches design temperature, then solid-state relay cuts off the power supply automatically, heats to stop; Simultaneously, instrument is controlled fan work by rights and big temperature overshoot can not occurred to guarantee the temperature in the heating chamber; Otherwise, continue heating, till reaching design temperature.Temperature in two chambeies can be controlled separately, and relevant control also can be coupled.When the relevant control of need coupling, need make the machine operation that is connected with connecting rod 7, drivening rod rotates or the hand rotation connecting rod, baffle plate 4 on the connecting rod is rotated, expose the perforate on the dividing plate 2, the size of perforate is regulated by baffle plate 4, and the temperature in two chambeies can exchange, to realize the relevant control work of dual chamber coupling.
