The invention discloses a water heater and a control method and device thereof. The method comprises the steps that the first temperature of a water tank of the water heater and the second temperature of a first heating device are detected; a first comparison result or a second comparison result is acquired, wherein the first comparison result is the compared value of the first temperature and the second temperature with the target set temperature of the water tank, the second comparison result is the compared value of the first temperature and the target set temperature, or the second comparison result is the compared value of the second temperature and the third temperature which is the water outlet temperature of the first heating device; the first operating state of the first heating device is controlled according to the first comparison result; and the second operating state of a second heating device and the third operating state of a third heating device are controlled according to the first operating state. The technical problem that the heating source of a water heater in the prior art is simplex is solved.
Description
technical field [0001] The present invention relates to the field of water heaters, in particular to a water heater and its control method and device. Background technique [0002] At present, in the water heater control scheme for heating the water tank, some only have a heat pump heat source to heat the water tank. The heat source is relatively single, and the temperature of the hot water outlet is not high; The control method of switching between the heat pump and the electric heating of the water tank by simply detecting the temperature of the water tank, when the hot water demand is small, the electric heating of the water tank takes a relatively long time to turn on and consumes a lot of energy. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] The embodiments of the present invention provide a water heater and its control method and device, so as to at least solve the technical problem of the single hea...
