Abstract

The utility model relates to a seamless liner of electric storage water heater, which comprises the left half and the right half liners. A silicone washer is underlay between the left half and the right half liners respectively jacketed with the left and right reinforcing gaskets and in tight coupling through a fastener. The outlet coupling and the inlet coupling on the liner are designed to be the screws with holes, which is fastened through the nut of the liner inner chamber. Thus the connection of the left and right liners and the connection of the inlet and outlet couplings on the liners become the seamless connection, so that the liner leakage issue can be completely solved.

Description

Water-storage electric heater does not have the weld seam inner bag

The utility model is that a kind of water-storage electric heater does not have the weld seam inner bag.

At present, the water-storage electric heater inner bag adopts metal stamping to become left half inner bag and right half inner bag, between a left side half inner bag and right half inner bag by being welded to connect, on inner bag, form weld seam, delivery port and water inlet directly are welded on left half inner bag and right half inner bag, the inner bag that this kind has weld seam generally is divided into enamel inner container and stainless steel inner container, for enamel inner container, adopt iron plate to strike out left half inner bag and right half inner bag, and by the welding both are connected to the weld seam inner bag, ward off enameling then, though that enamel material has is varied, common characteristic is; Corrosion resistance is good; acid-proof, alkali prevention; but fragility is big; be collided or produce the crack and can come off, cause in the commissure especially easily and get rusty and leak, relatively stainless steel inner container through enamel behind the rising-heat contracting-cold repeatedly; stainless steel is the corrosion-resistant ideal material; but general producer's technology, equipment fall behind, and welding portion is not taked safeguard measure and produced qualitative change or produce honeycomb when the welding, also can reduce antiseptic property and cause inner bag to leak.

The purpose of this utility model is to provide a kind of water-storage electric heater that can prevent effectively that inner bag from leaking not have the weld seam inner bag.

The utility model is achieved in that a kind of water-storage electric heater does not have the weld seam inner bag, comprise left half inner bag and right half inner bag, a left side half inner bag and right half inner bag are respectively equipped with apopore and inlet opening, be lined with packing ring between a left side half inner bag and right half inner bag, be with a left side on a left side half inner bag and right half inner bag respectively and strengthen pad and the right pad of strengthening, described left and right reinforcement pad is tightly connected a left side half inner bag and right half inner bag by securing member.

Can be connected with the screw of taking the mouth of a river out of and the screw of bringing the mouth of a river on the apopore of described inner bag and the inlet opening respectively, described take the screw at the mouth of a river out of and bring on the screw at the mouth of a river be with the silica gel circle, the nut that is positioned at gallbladder intracavity is anchored on the screw.

The utility model is because with the structure that is tightly connected that being connected of a left side half inner bag and right half inner bag adopts packing ring, pad to add screw, nut, make inner bag become no weld seam inner bag, effectively stopped the phenomenon that the inner bag junction leaks easily, simultaneously, the water outlet interface of inner bag adopts screw and Passscheiben with holes to be connected with the inlet opening with the apopore of inner bag with nut with the water inlet interface, cancelled water outlet interface weld seam on the inner bag and water inlet interface weld seam equally, guaranteed that on the whole inner container of electric water heater can not leak.

Below in conjunction with embodiment the utility model is described in detail:

Fig. 1 does not have the structural representation of weld seam inner bag for the utility model.

With reference to figure 1, water-storage electric heater does not have the weld seam inner bag and comprises a left side half inner bag 3 and right half inner bag 5 that adopts the corrosion-resistant metal drawing, a left side half inner bag 3 and right half inner bag 5 are respectively equipped with apopore and inlet opening, connect for convenience, be respectively equipped with a left side on a left side half inner bag 3 and right half inner bag 5, right connection flanging 8,9, a left side, right connection flanging 8, be lined with silicone gasket 4 between 9, be with a left side on a left side half inner bag 3 and right half inner bag 5 respectively and strengthen pad 2 and the right pad 6 of strengthening, a left side, the right pad 2 of strengthening, 6 are tightly connected a left side half inner bag 3 and right half inner bag 5 by screw 7 and nut 1 as securing member, have prevented that the inner bag junction from leaking because of the inner bag that has weld seam to cause.

In order thoroughly to solve the seepy question of inner bag on the whole, change original water outlet interface and water inlet interface that is welded on the inner bag into need not weld rib-loop with holes, be to be connected with the screw 10 of taking the mouth of a river out of and the screw 11 of bringing the mouth of a river on the apopore of inner bag and the inlet opening respectively, the described screw of taking the mouth of a river out of 10 and bring on the screw 11 at the mouth of a river and be with silica gel circle 12 respectively, the nut 13 that is positioned at gallbladder intracavity is anchored on the screw, also is provided with heat-generating pipe installing hole 14 on the inner bag.
