Heating method of instant electric water heater and instant electric water heater

Abstract

The invention discloses a heating method and system of an instant electric water heater and the instant electric water heater. The heating method comprises the following steps that first water temperature information of a first sensor is obtained; the first water temperature information is compared with a preset water temperature threshold value, and if the first water temperature information is smaller than the preset water temperature threshold value, a preheating command is sent; if the first water temperature information is larger than or equal to the preset water temperature threshold value, a heat preservation command is sent; state information of a water outlet valve is obtained; and the operation power of a heating body is adjusted according to the state information. The numerical value of the water temperature data of the heating body is compared with the numerical value of the preset water temperature data, the water temperature of an inner container of the heating body is kept at the preset water temperature, the heating body conducts preheating at low power all the time, the heating body has the high initial temperature, a user can conveniently and directly obtain water flow with the water temperature higher than the preset water temperature when opening the water outlet valve to drain water, and the temperature of the heating body can be quickly increased to the required temperature of the heating body when the heated water temperature is required by the user, so that a good feeling is brought to the user.

Description

technical field [0001] The invention belongs to the technical field of electric water heaters, and in particular relates to a heating method of an instant thermoelectric water heater and the instant thermoelectric water heater. Background technique [0002] Because the water in the kitchen is cold when the weather is cold, the existing kitchen is usually equipped with a water heater or a hot water faucet. For safety and environmental protection, the kitchen is generally equipped with an electric water heater. [0003] Due to the limited space for installing water heaters in the kitchen, the head of the household generally prefers to install small electric water heaters (commonly known as "small kitchen treasures"). A large water tank has a large volume, and the water in the water tank needs to be heated before use. Since the water in the water tank needs to wait for heating, and the water tank is prone to scale formation after repeated heating, the electric water heater for ...

AI Technical Summary

Problems solved by technology

If you choose to install a low-power instant thermoelectric water heater in order to avoid rearranging the wires or pulling the wires separately, since the heating body of the instant thermoelectric water heater is the main energy-consuming element, the temperature of the heating body rises slowly when the power of the heating body is small, and due to the low power of the instant thermoelectric water heater The heating switch is connected to the water outlet valve, and the water needs to be continuously released to heat the water flow. Before the heating water temperature is suitable, a large amount of cold water with a lower temperature needs to be released, which requires a lot of waiting and wastes water
