However, for the capacity increase function of the electric water heater, that is, in the state of water outlet and heating at the same time, since the hot water volume does not have a unidirectional law at this time, there is no accurate way to display the remaining hot water volume of the inner tank, which cannot allow users to truly Understand the actual amount of hot water that can be used in the inner tank, which will bring a bad user experience

Embodiment Construction
[0021] In the description of the present invention, it should be noted that for orientation words, such as the term "center", "horizontal", "longitudinal", "length", "width", "thickness", "upper", "lower" , "Front", "Back", "Left", "Right", "Vertical", "Horizontal", "Top", "Bottom", "Inner", "Outer", "Clockwise", "Counterclockwise " and other indication orientations and positional relationships are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, or in a specific orientation. The structure and operation should not be construed as limiting the specific protection scope of the present invention.
[0022] In addition, terms such as "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying rela...

The invention discloses a calculation method for the remainder hot water amount of a liner of an electric water heater. The calculation method for the remainder hot water amount of the liner of the electric water heater is characterized in that a controller calculates by virtue of a formula Q= (1-K)*Y to obtain the remainder hot water amount in a simultaneous water outlet and heating state; Y represents an original hot water amount, and is determined by a liner water temperature measured by a liner temperature sensor; and K represents the ratio of an actually-used hot water amount, and K=the actually-reduced hot water amount Ly / (the sum of an inherent capacity and the actually-increased hot water amount Lz). In this way, under the condition of water outlet and heating of the electric waterheater, the real-time and accurate remainder hot water amount can be obtained, and a user is enabled to know the real hot water use condition. The invention further provides the electric water heater.
Description
technical field [0001] The invention relates to the technical field of electric water heaters, in particular to a method for calculating the remaining hot water volume of an inner tank of an electric water heater. Background technique [0002] In order to facilitate users to understand the remaining hot water in the storage-type electric water heater, some storage-type electric water heaters have their own hot water display function. [0003] In the prior art, the water storage type electric water heater can only display the hot water volume of the inner tank under two states more accurately. One is the normal heating state when waiting to use the electric water heater, usually the amount of hot water increases with the rise of temperature; the other is the water outlet state after the user uses water, the amount of hot water decreases with the release of hot water. However, for the capacity increase function of the electric water heater, that is, in the state of water outl...
