Abstract

PURPOSE:To achieve alarming with a buzzer without any change, when a temperature reaches a set value, even if the setting is changed to a higher temperature than the present temperature on the way of a work, by providing a set value arrival detection section, a set value arrival storage section and an alarming section. CONSTITUTION:A heating appliance such as an iron is provided with a set value arrival detecting section 65, a set value arrival storage section 66, an alarming means 5, and when a temperature reaches an upper or a lower set value and a variable such as a voltage relating to the control of a load 4 is changed, a signal is detected and outputted for alarming. For example, a set value arrival detecting section 65 generating a pulse through the change in a voltage acorss a thermoswitch 3 connected in series with a heaer 4, a set value arrival storage section 66 storing the pulse, an alarming means 5 illuminating a display light 30 through the storage and generating a buzzer tone via an alarming buzzer control section 67, a stop switch 6, and a buzzer stop storage section 68 and the like are provided.
