Abstract

A liner for an electric water heater with a double heating device comprises that two cylindrical liners are of upper and lower arrangement and are separately provided with independent heating device, and a communicating tube is separately arranged on two sides of the two cylindrical liners, and the water inlet tube extrudes into the lower liner and is horizontally arranged, and an upper part of a water outlet tube extrudes into the upper liner, a lower part is parallel on the same surface with the water inlet tube along an external surface of a housing of the lower liner. The utility model has the advantages of simple structure, easy welding, high heat transfer efficiency and not producing the water-leaking phenomenon easily.

Description

A kind of inner container of electric water heater with double heater

The utility model relates to a kind of electric heater, particularly a kind of inner container of electric water heater with heater.

At present, popular inner container of electric water heater in the society is no matter be that form inner bag that two " 8 " font inner bags still add mozzle in the middle of two cylindrical shapes all is to utilize hot and cold water energy exchange in the last bottom inner container to reach the purpose of intensification, and two " 8 " font inner bag is when volume is big, the voltage endurance capability of inner bag is relatively poor, and is yielding; The shortcoming that adds the inner bag of mozzle in the middle of two cylindrical shape inner bags is the energy exchange that hot and cold water in the bottom inner container is gone up in the thickness influence of mozzle, secondly, the many more just difficult more welding of mozzle between two inner bags, weld seam is many, the chance of leaking is just many, and is higher to the technological requirement of welding, in addition, the inner bag of two separation is slower by heat transfer water speed, and efficient is low.

The purpose of this utility model provides the inner container of electric water heater that a kind of compressive resistance is bigger, simple in structure, welding procedure is simple, the thermal efficiency is higher.

The purpose of this utility model is achieved by the following technical solution: comprising: two cylindrical shape inner bags are arranged above and below, independently heater is arranged respectively, both sides at two cylindrical shape inner bags are respectively arranged with cross over pipe, water inlet pipe puts in the bottom inner container and along bottom level and places, the top of outlet pipe is stretched in the upper inner-liner, and the bottom along the housing exterior curved surface of bottom inner container and water inlet pipe side by side at grade.

The utility model has improved heat transfer efficiency because of adopting independently heater respectively, has cancelled middle mozzle, and cross over pipe is set in both sides, make welding procedure comparatively simple, be difficult for producing drainage, cross over pipe is placed on the inner bag both sides, the direct impact of internal gallbladder-heat water when having avoided the cold water water inlet, thereby the hot water use amount is big, in addition, and with two electrothermal tube heating, control respectively by control device, can arbitrarily control electric power by the user in winter and summer.

Below in conjunction with accompanying drawing the utility model is elaborated:

Fig. 1 is an internal structure schematic diagram of the present utility model;

Fig. 2 is A-A cutaway view of Fig. 1.

As shown in Figure 1, upper inner-liner 1 and bottom inner container 2 are arranged above and below, be provided with heater 31 in the upper inner-liner 1, be provided with heater 32 in the bottom inner container 2, top one side of the bottom of upper inner-liner 1 and bottom inner container 2 is provided with cross over pipe 71, opposite side is provided with cross over pipe 72, two cross over pipes two respectively independently inner bag be communicated with, water inlet pipe 4 puts in the bottom inner container 2 and along bottom level and places, the top of outlet pipe 5 is stretched in the upper inner-liner 1, the bottom along the housing exterior curved surface of bottom inner container 2 and water inlet pipe side by side at grade, as shown in Figure 2, sewage draining exit is arranged on the bottom of bottom inner container 2, be provided with in the bottom inner container 2 make water demineralization magnesium rod 8, and magnesium rod 8 is arranged on the top and vertical placement of sewage draining exit 6.

The top of outlet pipe 5 extend into the top of upper inner-liner 1 and omits lower position.
