Description

  The present invention is a microwave heating type dryer, in which an object to be dried is put in a removable cartridge and the cartridge is rotated, while absorbing the microwave energy to the load of the object to be dried uniformly and detachably attached to the turntable. The present invention relates to a structure of a daily-use drier that efficiently heats and dries by irradiating microwaves while inserting and rotating a cartridge, and a method for controlling a drying operation.

Conventional dryers are hot air dryers in which objects to be dried, mainly clothing, are placed in a drying container and simply rotated, and hot air is blown by oil, gas, or an electric heater.
When drying using oil, gas and electric heaters, it is difficult to design and control the temperature of the heater that produces hot air, and the drying process time cannot be set clearly. As a result, the setting of the drying time is inaccurate and long, and accordingly, the running cost is excessive, and the operation is carried out at a high temperature for a long time.
Explaining the shortcomings of the conventional technology, the heater drying method and other drying methods are also operated for a long time, and the reason is that the drying object is dried from the surface of the object to be dried. In addition, since the drying efficiency is deteriorated and the warm air temperature of the heater warm air is high, when the object to be dried is a cloth fabric, the cloth fabric is easily damaged.
In the conventional drying machine structure, the drying container is simply rotated to dry, so that the fabric of the object to be dried gets tangled and easily damages the cloth fabric. Therefore, it is difficult to control the heater temperature.
An object of the present invention is to solve such a problem. The object to be dried is characterized by microwave drying by individually dividing the object to be dried to improve the air flow on the surface of the object to be dried. It is characterized in that the drying object is dried at high speed by utilizing the fact that the drying object is uniformly dried to the inside and the drying object itself generates heat.

In the present invention, removable cartridges having a dehydrating function are separated into one or more, and the objects to be dried are inserted into the turntable in the drying chamber, so that the cloth fabric of the objects to be dried is not easily entangled. ing.
The feature of microwave drying is that it is uniformly dried up to the inside of the object to be dried and the drying object itself generates heat, so the immediate effect of drying is very high.
