Embodiment Construction

[0034] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] The invention provides a control method of an instant heating device. refer to figure 1 Shown is a flow chart of the first embodiment of the control method of the instant heating device of the present invention.

[0036] In this embodiment, the control method of the instant heating device includes:

[0037] Step S10, monitoring the input voltage of the instant heating device in real time;

[0038] Step S20, when it is detected that the input voltage changes, according to the changed input voltage and the currently set heating power, calculate whether the thyristor is in conduction during every preset number of commercial power cycles. The number of conducting cycles of the mains power in the state;

[0039] The instant heating device in the embodiment of the present invention may be an instant water dispens...

Abstract

The invention discloses a control method for an instant heating device. The control method includes the steps of monitoring an input voltage of the instant heating device in real time; when it is detected that the input voltage is changed, according to the changed input voltage and a currently set heating power, calculating, among each continuous preset number of electric supply cycles of a thyristor, the conduction number of the electric supply cycles which are in a conduction state; controlling the on and off states of the thyristor according to the calculated conduction number, so that theinstant heating heater performs heating according to the heating power. The invention also provides the instant heating device. The control method and the device solve the technical problem in the prior art that the actual heating power of a heating device is unstable due to the instability of the input voltage.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an instant heating device and a control method thereof. Background technique [0002] At present, devices that use instant heaters for heating, such as instant drinking water systems, instant water heaters, etc., generally adjust the voltage of the instant heater through the conduction and disconnection of the thyristor, and then control It operates according to the set heating power, and the heating power of the instantaneous heater can be adjusted in a large range through this adjustment method. Generally, after the power adjustment is completed, the heating device needs to operate stably according to the adjusted and set heating power. [0003] However, due to fluctuations in the mains power system due to various reasons, the input voltage of the heating device fluctuates, and when the existing heating device adjusts the thyristor, it is adjusted according to the...
