Microwave dryer

Abstract

The invention provides a microwave dryer which comprises a drying chamber, a supporting plate and a set of microwave drying devices. The top face, the bottom face and the peripheral side faces of the drying chamber are made of electromagnetic shielding materials. The left side and the right side of the supporting plate are each provided with a groove, the left side face and the right side face of the drying chamber are each provided with a flange, and the structures of the flanges correspond to those of the grooves. Each microwave drying device comprises a microwave generator, a temperature probe, a humidity probe and a base. Two doors in bilateral symmetry are arranged on the side face of the front portion of the drying chamber, and the end faces of the top face and the bottom face of the drying chamber are provided with two linkage switches corresponding to the doors. According to the microwave dryer, the microwave drying devices are arranged in furniture or on the back side of a plate, microwaves are transmitted from the inner layer of paint to the outer layer of the paint, the paint is dried from inside to outside, the paint on the inner layer and the paint on the outer layer are cured in sequence, even heating of the furniture is guaranteed, and therefore the obtained surface evenness and smoothness of the paint are both high.

Description

technical field [0001] The invention relates to the field of furniture processing equipment, in particular to a microwave dryer. Background technique [0002] Wooden furniture needs to be painted. After applying the paint, wait for the paint to dry before using it. At present, the most commonly used paint drying method is natural drying. For some furniture, baking drying is used. Natural drying takes a long time, while baking drying takes a short time, but energy consumption is large, and baking heating is not good for wood. . [0003] Another problem is that whether it is natural drying or baking drying, the drying order of the paint is from the outside to the inside, that is, the paint on the outer layer is cured first, and at this time the outer layer is solid and the inner layer is liquid. The liquid paint in the inner layer will seep out from the gaps or crevices formed after the outer layer is cured, and the result is that the flatness of the final paint surface is ...

Problems solved by technology

At present, the most commonly used paint drying method is natural drying. For some furniture, baking drying is used. Natural drying takes a long time, while baking drying takes a short time, but energy consumption is large, and baking heating is not good for wood.

[0003] Another problem is that whether it is natural drying or baking drying, the drying order of the paint is from the outside to the inside, that is, the outer layer of paint is cured first, and at this time the outer layer is solid and the inner layer is liquid.

The liquid paint in the inner layer will seep out from the gaps or crevices formed after the outer layer is cured, and the result is that the flatness of the final paint surface will be affected, and the finish of the paint surface will be poor.

[0004] CN102921618A patent application discloses a microwave dryer. By setting a microwave generator in the box, the furniture is heated from the inside to the outside, so that the liquid paint on the inner layer of the furniture is cured first, and the outer layer is cured later. However, according to our Daily life experience shows that the heating of objects by microwaves is uneven (such as our commonly used microwave ovens, which can obviously detect uneven heating of food after heating food), so this kind of microwave dryer cannot achieve uniform heating of furniture. Even if it is heated, it cannot completely solve the problem that the flatness of the furniture paint surface is affected after drying

[0005] In addition, the newly bought furniture also has the disadvantage of easily increasing the formaldehyde content in the indoor air, which is not good for human health. Even if the furniture drying device of the prior art can quickly realize the drying of the furniture, the dried furniture cannot be used immediately.
