The invention relates to the technical field of heat storage water tanks and discloses a calculation method and device for the amount of remaining hot water in a pressure-bearing-type heat storage water tank and a water heater. The calculation method comprises the steps that a practical temperature T practical of the pressure-bearing-type heat storage water tank acquired at a single temperature acquisition spot is obtained; the size V1 of an earlier-stage temperature detection blind zone, the size V2 of a middle-stage temperature sudden-dropping zone and the size V3 of a later-stage temperature detection blind zone are calculated; the amount eta1 of remaining hot water in the earlier-stage temperature detection blind zone is calculated; the amount eta2 of remaining hot water in the middle-stage temperature sudden-dropping zone is calculated; the amount eta3 of remaining hot water in the later-stage temperature detection blind zone is calculated; and the amount eta of remaining hot water in the pressure-bearing-type heat storage water tank is calculated according to the amount eta1 of remaining hot water in the earlier-stage temperature detection blind zone, the amount eta2 of remaining hot water in the middle-stage temperature sudden-dropping zone and the amount eta3 remaining hot water in the later-stage temperature detection blind zone. By adopting the calculation method anddevice, the amount of remaining hot water in the pressure-bearing-type heat storage water tank can be accurately calculated, and the control system and the product are simple in structure.
Description
technical field [0001] The invention relates to the technical field of pressure-bearing hot water storage tanks, in particular to a method and device for calculating the remaining hot water in a pressure-bearing hot water storage tank, and a water heater. Background technique [0002] With the improvement of people's living standards, users have put forward higher requirements for the use functions of water heaters with pressurized water storage tanks. For example, many users hope that water heaters with pressurized hot water storage tanks have the function of displaying the remaining hot water, so that users can understand the current water consumption of the pressurized hot water storage tank in real time and make timely adjustments. [0003] In the prior art, in order to obtain the remaining hot water volume of the pressurized hot water storage tank, the temperature collection points of the pressurized hot water storage tank are generally collected at different positions ...
