Water quality testing device and testing method for electric water heater and inner container thereof

Abstract

The invention discloses a water quality detection device for an inner tank of an electric water heater. Through the ultrasonic signal of the water in the inner tank of the electric water heater; the controller and the controller are respectively connected with the ultrasonic generator and the ultrasonic receiver, and are used to judge the internal temperature of the electric water heater according to the time difference between the ultrasonic signal sent by the ultrasonic generator and the ultrasonic signal received by the ultrasonic receiver. Gall water quality. The water quality detection device of the electric water heater inner tank of the present invention can enable the user to intuitively understand the water quality of the electric water heater inner tank such as turbidity, and then provide a basis for the user to judge whether the inner tank needs to be cleaned, thereby ensuring the cleanness of the bathing water. The invention also discloses an electric water heater and a detection method for the water quality of the inner container of the electric water heater.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a detection device and a detection method for the inner tank water quality of an electric water heater, and an electric water heater provided with the inner tank water quality detection device. Background technique [0002] Electric water heater is a relatively common electrical equipment. In order to protect the inner tank of the electric water heater, magnesium rods are generally installed in the inner tank. However, after the electric water heater is used for a period of time, due to the consumption of magnesium rods and long-term heating The generation of scale in the inner tank makes the water in the inner tank of the electric water heater become more and more turbid. However, due to the airtightness and opacity of the inner tank, when the water in the inner tank becomes turbid, and to what extent the water is turbid, there is no specific detection method at pr...

[0002] Electric water heater is a relatively common electrical equipment. In order to protect the inner tank of the electric water heater, magnesium rods are generally installed in the inner tank. However, after the electric water heater is used for a period of time, due to the consumption of magnesium rods and long-term heating The generation of scale in the inner tank makes the water in the inner tank of the electric water heater become more and more turbid

However, due to the airtightness and opacity of the inner tank, there is no specific detection method for when the water in the inner tank becomes turbid and to what extent the water is turbid.
