Electric heating vessel for liquids

Abstract

The invention provides an electric heating container for liquid. The electric heating container for the liquid comprises a container body and a scale treatment device, wherein the container body is used for containing the liquid and is an electric conductor used for being connected with a ground wire; the scale treatment device comprises a power source and a conductive scale adsorbing body, a positive electrode of the power source is connected with the container body, a negative electrode of the power source is connected with the scale adsorbing body, and a part of or the whole scale adsorbing body is located in the liquid; the specific value S / d of the superficial area S of the scale adsorbing body and the hardness d of the liquid is larger than or equal to 10<-4> mm<2> / ppm and smaller than or equal to 9*10<4>mm<2> / ppm. According to the electric heating container for the liquid, the relation of the specific value of the superficial area S of the scale adsorbing body and the hardness d of the liquid is reasonably set so that scale generated by the liquid in the heating process can be adsorbed to the maximum degree under the condition that the scale treatment device is not additionally provided with any auxiliary device and the scale removal effect can be improved.

Description

technical field [0001] The invention relates to a household appliance, in particular, the invention relates to an electrically heated container for liquids with a descaling device. Background technique [0002] At present, in people's daily life, the electric kettle is usually filled with tap water and boiled for drinking. There are the following problems in this way: [0003] 1. There are a lot of calcium ions and magnesium ions in the tap water. During the heating process of the water supply, a chemical reaction will occur to form a large amount of scale such as calcium carbonate and magnesium hydroxide, and some of the scale will be drunk with the boiled water; [0004] 2. The scale generated is easy to condense on the bottom of the kettle, which affects the thermal efficiency of the kettle, and the user needs to clean the scale in the bottom of the kettle frequently. [0005] In view of the above problems, the current method is to add positive electrode rods and negativ...

AI Technical Summary

Problems solved by technology

[0004] 2. The scale produced is easy to condense on the bottom of the kettle, which affects the thermal efficiency of the kettle, and the user needs to clean the scale in the bottom of the kettle frequently

[0005] In view of the above problems, the current method is to add positive electrode rods and negative electrode rods in the electric kettle. When the positive electrode rods and negative electrode rods are energized, the calcium ions and magnesium ions in the scale will be adsorbed on the negative electrode rods. Scale is formed on the electrode rod, which reduces the scale formed in the kettle. However, the relationship between the parameters of the electric kettle is not set properly, and the scale cannot be effectively removed.
