Embodiment

[0015] This embodiment is an electric water heater adopting a full-resistance isolation edge device, such as figure 1 As shown, the enamel liner 6 of the water heater is equipped with an electric heating rod (not shown in the figure), and the outer surface of the liner 6 is welded with an M-shaped liner bracket to form a first connected member adjacent to the charged device . The outer surface of the outer shell cylinder 3, which covers the inner tank, is provided with an outer shell hanger 2 for hanging the electric water heater, which constitutes a second externally connected member. The isolation insulator 5 made of nylon is located between the two connected members. While isolating the inner liner member from the outer shell member, it also acts on the inner liner bracket 4 through its own spacer action to connect the inner liner member to the fastening connector. The bolt 1 and the nut are insulated and isolated. The bolt 1 in the fastening connection passes through the shel...

Abstract

The invention relates to an improvement of insulated device, and an electric water heater with said device, belonging to the household appliance technique. The inventive all-baffle insulated device comprises a first connected element near the electric appliance, a outwards second connected element, a separation insulated element between said two connected elements and a connection element. Said separation insulated element can at least separate the first connected element from the connection element; said connection element is through the first connected element, the separation insulated element and the second connected element to connect them. Therefore, if the first connected element is electrified by electric leakage, the other elements will not be electrified to confirm the safety. Compared to present technique, the invention can avoid the electric leakage to reach the safety standard of household appliance.

Description

Technical field [0001] The invention relates to an improvement of an insulating device, and at the same time, an electric water heater adopting the device is designed, and belongs to the technical field of household appliances. Background technique [0002] The insulation performance of household appliances has always been an issue of concern and research. The national standard GB 4706.1 "Safety of Household and Similar Electrical Appliances" specifies the safety requirements for household appliances in detail. The search found that the Chinese invention patent with the application number 031062628 discloses an insulating assembly and an electric water heater using the insulating assembly. The insulating assembly includes a bracket for the insulated object one, a bracket for the insulated object two, an insulating pad, and a connector. , And an insulating sleeve, the insulating pad is arranged between the bracket of the insulated object one and the object two, the above-mentioned...
