specific Embodiment approach

[0064] 1. Sleeve type double inner tank multi-purpose electric water heater with single water inlet structure

[0065] (1) Used to provide hot water for washing, bathing and heating

Embodiment 1

[0066] Embodiment 1 (dumbbell-shaped inner layer liner)

[0067] Such as figure 1 , 2 As shown, the sleeve-type double-inner multi-purpose electric water heater of this embodiment is composed of an electric water heater main body 1 including at least an operation control device and an insulation layer, an electromagnetic heating device 2 with a cooling cavity, and an inner tank 3. The electromagnetic heating The heating end of the device is inserted into the inner tank, and the electromagnetic heating device and the inner tank are completely sealed through the threaded connection device and the sealing ring on the mounting seat of the electric heating device. The more specific implementation method is as follows:

[0068] The described liner is a sleeve-type double liner, which includes an inner liner 31 and an outer liner 32. The sleeve-type double liner consists of an inner sleeve 311, an outer sleeve 321 and a built-in inner sleeve. The upper head 312, the upper head 322...

Embodiment 2

[0074] Embodiment 2 ("mushroom-shaped" inner liner)

[0075] Such as image 3 , 4As shown, the only difference between this embodiment and Embodiment 1 is that the cylinder wall at the bottom end of the inner sleeve 311 and the annular positioning boss 323b of the lower head 323, the cylinder wall at the top end of the inner sleeve and the built-in upper The flanging 312b at the opening of the head 312 connects the lower head 323, the built-in upper head 312 and the inner sleeve 311 as a whole, through the ring flange 312a around the built-in upper head and the surrounding of the lower head The annular flange 323a connects the outer sleeve 321 with the built-in upper head 312 and the lower head 323, between the inner sleeve 311, the outer sleeve 321, the lower head 323 and the built-in upper head 312 Form the outer layer liner 32 that is a ring-shaped closed inner cavity; the upper head 322 is connected as a whole through the wall at the top of the outer sleeve to form a clo...

Abstract

The invention relates to a sleeve type double-liner multi-purpose electric water heater, which is at least composed of a main electric water heater body, an electric heating device and sleeve type double liners, wherein the main electric water heater body at least comprises an operation control device and a thermal insulating layer. The bottom of the inner-layer liner of the sleeve type double liners is closed, the top of the inner-layer liner of the sleeve type double liners is open, and the inner-layer liner has various shape structures. The outer-layer liner is arranged at the periphery of the inner-layer liner and is in an annular closed shape. The top of the sleeve type double liners is provided with an installing base for the electric heating device, and the heating end of the electric heating device is inserted into the liners and is completely sealed with the liners through a threaded connection device and a sealing ring. The sleeve type double-liner multi-purpose electric water heater adopts a single way or double ways for water feeding and is provided with the double liners and double hot-water supply systems, so that the sleeve type double-liner multi-purpose electric water heater can respectively supply hot water for washing, bathing and heating when in use, can also respectively supply hot water for washing and bathing for two independent hot-water conveying pipelines at the same time, and can further supply hot water for washing and bathing for one hot-water conveying pipeline. The sleeve type double-liner multi-purpose electric water heater has the characteristics of compact structure, small size, high structural strength of the liners, remarkable energy saving effect and the like, and can meet different installation and use requirements.

Description

technical field [0001] The invention relates to an electric water heater, in particular to a multipurpose electric water heater with sleeve-type double inner tanks. Background technique [0002] Among the electric water heaters of the prior art, the electric water heaters for bathing and domestic hot water generally do not have the function of supplying hot water for heating, and the electric water heaters for heating water do not have the function of providing hot water for bathing. And domestic hot water function. [0003] Closed water storage electric water heaters for hot water for washing and bathing all have a single inner tank structure. Due to the large volume of the inner tank and the high water pressure entering the inner tank, the requirements for the structural strength of the inner tank are also high. [0004] There are also electric water heaters with upper and lower structure water tanks. The structure of the water tanks is not compact, and the volume is gene...
