Abstract

The invention relates to an instant heating water boiler, which comprises a water tank, a water pump, a control device and a heating container, wherein the heating container comprises a heating part to which a heating film is attached; the heating container further comprises a dry combustion detection part higher than the heating part; the dry combustion detection part is provided with a sensing device for detecting the water level in the dry combustion detection part; the sensing device is electrically connected with the control device; and the control device is used for controlling the working state of the heating part according to a signal of the sensing part. The water supply step of the control method comprises a first water supply stage for controlling a water pump to supply water to a thick film heater by using the control device, a stopping stage for heating water in the thick film heater to a set temperature and a second water supply stage for controlling the water pump to supply water continuously. When the heating part of the instant heating water boiler is started for heating, an internal flow channel is in water-filled state, so that the risk of dry combustion damage is avoided, and the service life of the entire boiler is prolonged.

Description

technical field

[0001] The invention relates to the technical field of kitchen appliances, in particular to an instant water boiler and a control method thereof. Background technique

[0002] The existing household instant water boilers that use heating containers are usually implemented in the following ways in order to ensure the rapid water outlet and the temperature of the water outlet:

[0003] The first method: first dry-boil the high-power instant water boiler, then the water quickly passes through the flow channel of the instant water boiler and continues to heat to form high-temperature water;

[0004] The second method: on the basis of the first method, increase the temperature control to realize the power or flow adjustment of subsequent heating to ensure the temperature of the outlet water.

[0005] However, in the first way, due to the dry heating of the high-power instant water boiler, the temperature rises rapidly, which can easily damage the thick-film heati...
