The circuit behind the secondary winding of the high-voltage transformer is a high-voltage circuit which mainly comprises a magnetron, a high-voltage capacitor, a high-voltage transformer and a high-voltage diode.

2) A magnetron. The magnetron is the heart of the dryer and the microwave energy is generated and emitted therefrom. When the magnetron works, high pulsating direct current anode voltage and cathode voltage of about 3-4V are needed. The voltage doubling rectifying circuit composed of the high-voltage transformer, the high-voltage capacitor and the high-voltage diode provides working voltage meeting the requirements for the magnetron.

The circuit between the primary winding of the high-voltage transformer and the power inlet of the dryer is a low-voltage circuit (also comprises a control circuit), and mainly comprises a protective tube, a thermal circuit breaker protective switch, an interlocking microswitch, a lighting lamp, a timer, a power distributor switch, a turntable motor, a fan motor and the like

3) A timer: dryers generally have two timing modes, namely mechanical timing and computer timing. The basic function is to select the set working time, and after the set time, the timer automatically cuts off the main circuit of the dryer.

4) A time power controller: different powers are selected to dry different kinds and quantities of clothes. The time power distributor is used for adjusting the average working time of the magnetron (namely the proportion of 'working' time to 'stopping' time when the magnetron works intermittently), thereby achieving the purpose of adjusting the average output power of the dryer. The mechanical control type dryer generally has 3-6 gears, and the computer control type dryer can have more than 10 gears, and automatic adjustment is realized through computer fuzzy control.

5) Interlocking micro-switches: the interlocking microswitch is an important safety device of the dryer. It has multiple interlocking functions and is controlled by a door opening button of a furnace door or a door opening button on a door handle of the furnace door. When the door is not closed or opened, the circuit is cut off to stop the drier.

6) Thermal circuit breaker: the thermal break is an element for monitoring the operating temperature of the magnetron or the oven chamber. When the working temperature exceeds a certain limit value, the thermal breaker can immediately cut off the power supply, so that the dryer stops working.

7) A drying cavity: also known as a resonant cavity, which is where the clothing is heated, is made of a metal plate coated with a non-magnetic material. The left side and the top of the drying cavity are both provided with vent holes. The microwaves, which are fed into the drying chamber through the wave guide, are reflected back and forth in the chamber wall, passing through and over the laundry each time they are propagated. When designing a microwave drying cavity, the side length of the oven drying cavity is usually made to be multiple of 1/2 microwave guided wave wavelength, so that when wet clothes are heated, resonance can be kept in the cavity, and the resonance range is properly widened.

8) Waveguide tube: microwave power generated from the magnetron is transmitted to the cavity to heat the clothes.

9) A human-shaped die: is used for fixing the clothes, so that the clothes keep a vertical and wrinkle-free state. The human-shaped mold is provided with a vent hole; for air drying the clothes;

10) rotating the working table: the rotary worktable is arranged at the bottom of the furnace chamber, has a certain height from the furnace bottom, and is driven by a small motor with the rotating speed of 5-6 r/min, and the rotating speed can be adjusted according to the requirement.

11) Oven door: the oven door is an inlet and an outlet of clothes and is also an important component of the oven chamber of the microwave drying equipment. The requirement is high, namely the heating condition of the clothes in the oven cavity can be observed from the outside of the door, and the microwave cannot be leaked out. The oven door consists of a metal frame and a glass observation window. The glass interlayer of the observation window is provided with a layer of metal microporous net, which can not only see clothes through the metal microporous net, but also prevent microwave leakage. Since the mesh size of the metal mesh in the glass interlayer is precisely calculated, the penetration of the microwave can be completely blocked. The microwave drying device is a barrier for preventing microwave leakage of the whole microwave drying device.

12) A switching system: in order to prevent the leakage of microwaves, a switching system of the microwave drying equipment consists of multiple safety interlocking microswitch devices. The microwave drying device can not work if the oven door is not good, and the microwave drying device does not work, namely the problem of microwave leakage is not mentioned.

13) Anti-trough: in order to prevent the microwave from leaking out from the gap between the oven door and the cavity after the oven door of the microwave drying equipment is closed, a choking groove structure is arranged around the oven door of the microwave drying equipment, or a door seal strip made of a material capable of absorbing the microwave, such as silicon rubber, is arranged in the choking groove structure, so that a small amount of microwave which is possibly leaked can be absorbed. The choking groove is a special-shaped groove structure arranged in the door and has the function of guiding the microwave to reverse the phase. At the entrance of the anti-slot, the microwave is cancelled by the reflected wave in the reverse direction, so that the microwave does not leak.

14) A hygrothermograph: the humidity sensor is used for measuring the humidity inside the drying box so as to guide a later system to control the opening and closing of the motor.

15) The ultraviolet sterilization device is mainly used for ultraviolet sterilization of clothes. Which may be placed on top of the drying box. The exterior minimizes the use of metal to prevent sparking during microwave heating.

16) A fragrance spray system: consists of a storage container, a spray nozzle and a liquid sensor. The aim is to spray fragrance on the clothes after the clothes are dried, so that the clothes still keep a certain fragrance after being taken out. The storage container can store a certain volume of spice or perfume, and the range of the spice or perfume is 100-1000 ml. The purpose of the liquid sensor is to monitor the remaining amount of perfume in real time and to alarm when the remaining amount is less than 10% of the preset value.
