The present invention provides a high-frequency heating apparatus which can heat the inside of the subject to be heated by high-frequency heating, and can apply scorch onto the surface of the subject to be heated. The high-frequency heating apparatus comprises a heating room for storing therein a subject to be heated, a heating unit that is provided at the upper portion of the heating room and performs heater heating, a high-frequency generating unit that is provided at the bottom of the heating room and generates a high-frequency wave to perform high-frequency heating, a high-frequency heating element having a high-frequency heat generating film on its rear surface, and a saucer for placing thereon the subject to be heated, in which a gap is provided between the high-frequency heating element and the saucer. Hereby, scorch can be applied onto a surface of the subject to be heated.

High-frequency heating apparatus with browning function of food

An object of the present invention is to provide a high frequency heating apparatus having a steam generating function in which a time required for evaporation of dropped water can be remarkably increased when water is dropped onto an evaporation tray and the heating efficiency is high. The high frequency heating apparatus has a steam generating function that includes a high frequency generator and a steam generator that includes an evaporation tray provided on the bottom surface of a heating chamber in which a heating target is mounted and a heater device for heating the evaporation tray to generate steam in the heating chamber, wherein the heater device is constructed as a heater device () having a sheathed heater () embedded in an aluminum die cast (), and the heater device is directly attached to the back side of the evaporation tray ().

Steam generation function-equipped high-frequency heating device

A high frequency heating apparatushaving a high frequency generating portionand a steam generating portionfor generating steam into a heating chamberfor accommodating a thing to be heated and serving to supply at least one of a high frequency and steam into the heating chamber, thereby heating the thing to heated, includes a panwhich serves to mount the thing to be heated thereon and is provided to be upward removable apart from a bottom face of the heating chamberat a predetermined interval, thereby dividing a space in the heating chamber, steam delivery meansfor supplying the steam generated by the steam generating portioninto an upper space positioned above the pan, and preheating meansfor raising an atmospheric temperature in the heating chamber.

High-frequency heating apparatus

A purpose of the present invention is to provide a cooker for high-frequency heating apparatus which can heat the inside of the subject to be heated by high-frequency heating, and can apply the scorch onto the surface of the subject to be heated. In the present invention, the cooker for high-frequency heating apparatus includes a high-frequency heating element and a saucer made of metal. In the cooker, the saucer is made of metal and is placed on the high-frequency heating element. Furthermore, a gap is provided between the high-frequency heating element and the saucer. Hereby, the inside of a subject to be heated is heated by high-frequency heating, and scorch can be applied onto a surface of the subject to be heated.

Cooker for high-frequency heating apparatus

A heating cooking apparatus utilizes a sensor of the type used in a conventional heating cooking apparatus. The change in the resistance of the sensor due to a temperature change is converted to a level representing the corresponding voltage change and this sensor level is utilized along with a level corresponding to a preset temperature of a temperature control level so selected that heat sources is turned on when the sensor level is less than this level and the heat sources is turned off when this level is exceeded so as to eliminate the occurrence of any overshooting irrespective of the presence or absence of preheating, that is, at various starting temperatures as well as in various operating conditions including one where a door is opened during the cooking and another where the cooking is interrupted due to an erroneous operation, thereby ensuring the best cooking result.

Apparatus for cooking by electric heating including means for providing

A heating apparatus measures the operation time and the inoperative time using an operation equation to switch the magnitude of the thermal supply of the heating apparatus in accordance with the calculated values. The heating apparatus includes a heater as a heating thermal supply, a heating chamber to be heated by the heater, a driving device for controlling the supply energies to the heater, a parameter operation device for calculating, in accordance with a given operation equation, the parameter corresponding to the supply energies to the heater, an output deciding device for comparing the parameter operation value obtained by the parameter operation device with the given target value to decide the output level of the heating thermal supply. The parameter operation value is increased in accordance with the given operation equation by the parameter operation device during the energization into the heater, and when the value has reached the given value, the output deciding means increases or cuts off the average power to the heater.
