Embodiment 1

[0019] According to an embodiment of the present invention, an embodiment of a method for controlling electric heating of a water heater is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and , although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0020] Figure 4 is a schematic diagram of an optional water heater according to an embodiment of the present invention, such as Figure 4 As shown, the above-mentioned water heater includes: a first temperature-sensing package and a second temperature-sensing package arranged on the water tank, and an electric heating device arranged on the upper part of the water tank, and the second temperature-sensing package can be arranged on the upper part of the water tank The temperature-...

Embodiment 2

[0083] According to an embodiment of the present invention, an embodiment of a device for controlling electric heating of a water heater is provided.

[0084] image 3 It is a schematic diagram of a device for controlling electric heating of a water heater according to an embodiment of the present invention, such as image 3 As shown, the device includes:

[0085] The acquiring module 31 is configured to acquire the first temperature detected by the first temperature sensing package and the second temperature detected by the second temperature sensing package.

[0086] In an optional solution, since the hot water in the water tank flows out from the hot water outlet pipe on the upper part of the water tank, and the cold water flows in from the cold water inlet pipe on the lower part of the water tank, there is a temperature difference between the upper part of the water tank and the lower part of the water tank, which can be passed through the upper part of the water tank. T...

Abstract

The invention discloses a method and device for controlling electric heating of a water heater, a water heater and a heat pump water heater. Wherein, the method includes: acquiring the first temperature detected by the first temperature sensing package and the second temperature detected by the second temperature sensing package; monitoring whether the temperature decrease value of the first temperature within the first predetermined time exceeds the first predetermined temperature Set value; when the temperature decrease value of the first temperature within the first predetermined time exceeds the first preset value, monitor whether the second temperature meets the preset condition, wherein the preset condition includes: the second temperature within the unit time The temperature drop value, and the second temperature detected in the continuous sampling interval; when the second temperature satisfies the preset condition, the electric heating device is turned on. The invention solves the technical problem that the heating efficiency of the heat pump water heater in the prior art is low and cannot satisfy users when a large amount of water is consumed.

Description

technical field [0001] The invention relates to the field of water heater control, in particular to a method and device for controlling electric heating of a water heater, a water heater and a heat pump water heater. Background technique [0002] Water heaters are well known as a commonly used household appliance. In order to save energy, more and more families use air source heat pump water heaters. water temperature. However, when the existing heat pump water heater is actually used by the user, if the user consumes too much hot water at a rate greater than the heat pump power of the water heater, it will not be able to meet the user's water demand, and the water temperature will drop sharply, which will affect the user's use. [0003] Aiming at the problem that the heat pump water heaters in the prior art cannot meet the needs of users in large water consumption, no effective solution has been proposed yet. Contents of the invention [0004] Embodiments of the present...
