Electric water heater and assembly method of electric water heater using large plastic sleeve

Abstract

The invention provides an electric water heater and an electric water heater assembly method using a large plastic sleeve. The electric water heater comprises an inner container, an outer shell, a water inlet pipe, a water outlet pipe, a magnesium rod, a water inlet pipe sleeve, a water outlet pipe sleeve and a magnesium rod sleeve. One ends of the various sleeve bodies are narrow-mouthed ends, and the other ends of the various sleeve bodies are flared ends. Each narrow-mouthed end is provided with an inner container follow-shape surface which is characterized that a middle hole edge of the inner container follow-shape surface of each plastic sleeve is provided with a horn-mouth shape elastic cantilever extending inward. The free end of each horn-mouth shape elastic cantilever is a cylindrical installation guide. The water inlet pipe sleeve, the water outlet pipe sleeve and the magnesium rod sleeve are connected into a whole in a sequential and side-by-side mode. The electric water heater is reasonable in structural design, high in installation efficiency and good in tightness. In the electric water heater assembly method using the large plastic sleeve, the separated or integrated large plastic sleeve is firstly clamped on a magnesium rod seat, the water inlet pipe and the water outlet pipe, wherein the magnesium rod seat, the water inlet pipe and the water outlet pipe are arranged outside the inner container. Only once inner container leakage detecting is needed, and thus processing step is simplified, and production efficiency and foaming quality are improved.

Description

technical field [0001] The invention belongs to the technical field of electric water heater manufacturing, and in particular relates to the improvement of the structure and assembly process of large plastic sleeves for electric water heater inlet pipes, water outlet pipes and magnesium rods, specifically an electric water heater and an electric water heater assembly method using large plastic sleeves. Background technique [0002] The structure of the existing large plastic sleeve is a common trumpet shape. One end of the narrow mouth is sleeved on the water inlet and outlet pipes outside the inner tank of the water heater, and one end of the flared mouth is sleeved on the outer surface of the water heater shell. Because the contact between the large plastic sleeve, the water inlet and outlet pipes and the shell is not firm , When the water heater is foaming, the large plastic sleeve is easy to separate from the shell, and problems such as material leakage are prone to occur...
