Filed: 1986-12-26
Abstract: PURPOSE:To reduce time and electric power required for incineration by a method wherein after garbage is previously dehydrated by a dehydrator, the garbage is dried by irradiation with microwaves and then is burnt by receiving heat energy from a microwave heating element. CONSTITUTION:First, a garbage collector 6 is placed on a rotating disk 23 in a dehydrating vessel 22 and then the garbage is dehydrated by the rotation of the disk 23 after a cover 25 is closed. After the completion of dehydration, the garbage is placed in a cylindrical device 2 and a magnetron 18 is oscillated. Microwaves propagate in a waveguide 15 and penetrate through an insulator 5 with a low dielectric constant and through the collector 6 and then supplied into the device 2 as a metal cavity. The garbage in the collector 6 generates heat after absorbing the microwaves and then are dried. On the other hand, a microwave absorbing and heating element 8 generates heat on absorbing the microwaves. As the element 8 has columnar shape, the garbage in the collector 6 takes the form of surrounding the element and the garbage is ignited and burnt by this heat.

Abstract: PURPOSE:To improve comfort in a controller for a warm air space heater. CONSTITUTION:The controller for a warm air space heater comprises a PMV value calculator 11 which inputs a room temperature and a radiation amount and calculates a PMV value, a combustion amount setter 12 which compares a PMV output from the calculator with a target PMV value, controls a burner 4 and a convention fan 5, and a target PMV setter 13 for setting the target PMV value to a higher value if the PMV output from the calculator falls within a predetermined PMV value. Accordingly, when a PMV value does not become the target PMV value at the time of starting f heating, it can be room heated to a neutral state of a thermal balance of a human body neither too hot nor to cold to match a state of a space to be, heated. In addition, when the PMV value always falls within the predetermined value at the time of starting space heating, the target PMV value is set higher. Accordingly, the combustion amount is so set higher as to become the target PMV value by the combustion amount setter, thereby rapidly and effectively performing space heating to realize a comfortable state for users.
