Problems solved by technology

This way of working has no obvious adverse effects on heating food, so it can be applied to microwave ovens; but when drying clothes, it will cause local burns of clothes, if clothes are attached with metal products (such as metal zippers, metal buttons) , metal ornaments), will also produce obvious sparking phenomenon
Existing technology does not solve this problem
[0006] In addition, most of the existing design schemes of microwave clothes dryers only use a microwave oven magnetron, which has a low average microwave power density, long drying time, uneven drying, and poor drying effect; (For example, the utility model patent with the application number of 95217354.9) adopts two microwave oven magnetrons in the same direction or even a combination of multiple magnetrons. Due to the aforementioned reasons, this will make the peak value of the microwave pulse power higher and the ignition will be more serious. More damage to clothing

Embodiment 1

[0051] A microwave clothes dryer has been produced, the shape is a rectangular cabinet, the size is: 550mm (width) × 1200mm (height) × 400mm (depth), the volume is 260L, including the structural frame, shell, cabinet door 2, control device and Components such as the control panel 1, the cabinet door 2 can prevent microwave leakage, the inner wall of the cabinet is made of plastic-sprayed colored steel plates, the magnetron A3 and the excitation chamber A29, the magnetron B4 and the excitation chamber B30 are located on the right side of the reaction chamber 6, dehumidification The exhaust fan 27 is arranged on the right side of the top of the cabinet.

[0052] Magnetron A3 and magnetron B4 are magnetron types of household microwave ovens. They are arranged up and down on the right side of the reaction chamber 6. The directions of magnetron A3 and magnetron B4 are perpendicular to each other. The above magnetron B4 is placed horizontally, and the magnetron A3 below is placed pe...

Embodiment 2

[0060] Made another microwave clothes drier, the shape and most parts, size, circuit are identical with embodiment one. The difference is that the inner wall of the cabinet is a thin stainless steel plate, and a magnetron C28 is added on the upper part of the reaction chamber 6 in the machine. The magnetron C28 is still a household microwave magnetron type, and its high-voltage power supply still adopts the full-wave rectification circuit including the power adjustment device 21 as mentioned above. The excitation chamber C31 of the magnetron C28 still has a rectangular waveguide opening on the wall of the reaction chamber 6 , and the microwave generated by the magnetron C28 still enters the reaction chamber 6 through the rectangular waveguide opening. The magnetron C28 is perpendicular to the existing magnetron A3 and magnetron B4, and the three magnetrons are perpendicular to each other. The rectangular waveguide port of the excitation cavity C31 of the magnetron C28 is conne...

Embodiment 3

[0064] The third microwave clothes dryer has the same appearance and most parts, dimensions and circuits as in Embodiment 1. The difference is that its reaction chamber 6 is a pentagonal cabinet, such as Figure 13 shown. The right side of the reaction chamber 6 is not a plane, but forms two sides with an included angle of about 120 degrees. The magnetron A3 and the magnetron B4 are respectively installed on both sides of the included angle. Magnetron A3 , magnetron B4 and their corresponding rectangular waveguide openings are still perpendicular to each other on a certain plane perpendicular to the horizontal plane. The high-voltage power supplies of the magnetron A3 and the magnetron B4 are still full-wave rectification circuits including the power adjustment device 21 .

[0065] The total microwave power is 300-1200W, of which: the power of each magnetron is 150-600W. The total input power is 1800W. The power supply is AC 220V single phase.

Abstract

The present invention relates to a microwave clothes drying machine. It is characterized by that said invention adopts the following technical measures: remaking half-wave voltage-multiplying rectifier circuit of high-voltage power supply of domestic microwave oven magnetron into full-wave rectifier circuit containing power regulation device, setting mutually perpendicular microwave activation directions to construct stereo microwave and adopting polygonal cabinet body or cylindrical or drum type reaction cavity, etc. to reduce microwave pulse peak power and raise microwave average power density, so that the microwave power can be flexibly regulated according to the number of clothes and the safety of drying process also can be raised.

Description

technical field [0001] The invention relates to a drying device for eliminating liquid from solid materials or products, in particular to a drying machine which utilizes microwave action, mainly for textiles such as clothes, and is suitable for use in places such as homes and hotels. Background technique [0002] Microwave is an electromagnetic wave with a frequency range of 300MHz to 300GHz. Household microwave ovens generally use a working frequency of 2450MHz. When the field strength reaches a certain level, polar water molecules will rub violently to generate heat, which will increase the temperature of the object on which the microwave acts, and achieve the purpose of cooking food. In the industry, microwaves are also used to dry materials containing water, such as Chinese medicinal materials and pills, according to this principle. [0003] In recent years, people have successively proposed to use microwaves to dry clothes and make household microwave clothes dryers, a...
