Description

TECHNICAL FIELD

[0001] The utility model belongs to electric water heater technical field, especially relate to a heating pipe device with electrode. BACKGROUND

[0002] At present, the electric heating tube used on the electric water heater is mostly single function, and can only play a conventional heating role. If other functions such as water level detection and electrode corrosion prevention are required, new holes need to be opened on the inner container for assembling electrodes. Since the electrodes are fixed in the inner container through threads, adverse phenomena such as tooth slipping, tooth misalignment, insufficient pressing force and leakage may occur during assembly. Moreover, the increase of the holes in the inner container reduces the pressure resistance of the inner container, and there are hidden dangers of water leakage and water seepage during long-term use.

[0003] In view of the above technical problems, the applicant has searched some prior art, for example, patent publication No. CN200920148346.0, which mainly uses the technical means of arranging the water level electrode, reference electrode and heating tube on the flange plate as a whole, which not only facilitates the installation and removal of the electrodes and reduces the number of holes needed to be opened on the inner container of the electric water heater. After the applicant's analysis, the disadvantages of this technical solution are: the part of the electrode located inside the flange plate needs to be sealingly connected with the flange surface, and currently a sealing ring is generally used, which makes the electrode, flange plate and electric heating tube form a whole. When the electrode is damaged, the flange plate needs to be disassembled as a whole to repair or replace the electrode, which is relatively cumbersome on the one hand, and the frequent disassembly and assembly of the flange plate may cause the connection between the flange plate and the electric water heater to be imprecise, thereby existing the hidden danger of water leakage.
