Description

Technical Field

[0001] The utility model relates to the technical field of electric water heaters, in particular to a double-tank electric water heater. Background Art

[0002] The dual-tank electric water heater is an energy-efficient household appliance that uses two independent heating tanks to control the heating of the two tanks separately, achieving more flexible water demand. Its main advantages include: fast heating, energy saving, safety and reliability, and continuous and stable hot water supply. The dual-tank design not only shortens the heating time, but also saves energy by heating only one tank when water consumption is low. In addition, many dual-tank electric water heaters are equipped with intelligent control systems, and users can set different heating modes according to their needs, further improving the convenience and comfort of use.

[0003] Traditional dual-tank electric water heaters work through two independent heating tanks, each of which is equipped with an electric heating tube. Users can choose to heat one or two tanks according to their water demand. When the heating is started, the current passes through the electric heating tube, converting the electrical energy into thermal energy, and quickly heating the water in the tank. The advantage of the dual-tank design is that when the water consumption is small, only one tank can be heated to save energy; when the water consumption is large, both tanks can be heated at the same time to ensure a continuous supply of hot water. The entire system is usually equipped with a temperature control device and a safety protection mechanism to ensure a safe and reliable heating process.

[0004] The design of traditional double-tank electric water heaters mainly focuses on heating efficiency and capacity. There is no special filtration system for water quality filtration, which makes it impossible to effectively remove impurities, sediments and microorganisms in the water. The minerals and impurities in the water are easily deposited in the heating tube and water tank during the heating process, forming scale, which not only affects the heating efficiency, but also shortens the life of the equipment. Utility Model Content

[0005] In order to make up for the above deficiencies, the utility model provides a double-tank electric water heater, which aims to improve the problem that traditional double-tank electric water heaters are difficult to filter incoming water, resulting in the inability to effectively remove impurities, sediments and microorganisms in the water, making it easy for minerals and impurities in the water to be deposited in the heating tube and the water tank during the heating process, forming scale, which not only affects the heating efficiency but also shortens the life of the equipment.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a double-tank electric water heater, comprising an outer shell, a filter bin fixedly connected to the interior of the outer shell, a water inlet pipe fixedly connected to the interior of the filter bin, a sealing top plate slidably connected to the top of the filter bin, a filter tank connected to the inner thread of the sealing top plate, a rotating sleeve slidably connected to the outer wall of the sealing top plate, a gear ring fixedly connected to the inner wall of the rotating sleeve, an outer wall of the gear ring rotatably connected to the interior of the sealing top plate, a gear rotatably connected to the interior of the sealing top plate, the gear meshing with the gear ring, a screw connected to the inner thread of the gear, a positioning assembly provided on the outer wall of the sealing top plate, and the positioning assembly used to position the sealing top plate.
