Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037]The present invention takes a double-layer circular pipe body as an example to introduce its internal structure in detail. Of course, according to the structure of the present invention, it can also be extended to a single-tank three-layer pipe body and theoretically more layers. Similarly, the heating element The space layer will also increase accordingly, and from the inside to the outside, for example, the heating element of the second layer can be divided into four symmetrical parts along the longitudinal direction, and each part can be set to give different power, that is, a variety of heating working modes. Of course, the use of three-layer pipe body water flow channel and multi-mode heating method in a single tank will get a good heating effect, but the practicability of more than three-layer pipe body water flow channels ...

Abstract

The invention provides a single-tank, double-pipe and bidirectional electric heating device and an air energy instant electric water heater. The single-tank, double-pipe and bidirectional electric heating device comprises a cylindrical tank body, the two ends of the tank body are connected with an upper end cover and a lower end cover in a sealing mode, the lower end cover is provided with a water inlet, a water outlet and a binding post, the tank body is internally provided with two layers of concentric pipe bodies which are an inner pipe body and an outer pipe body, an electric conduction heating body is arranged on a space layer between the inner pipe body and the outer pipe body, and a communicated water flow channel is formed by the inner channel of the inner pipe body and the annular channel between the tank body and the outer pipe body. The path length of water flow is increased, and the heating area of the water flow pipe bodies is increased by placing pipe bodies into the single tank body to divide the space inside the tank body, the process of obtaining the heating energy directly and bidirectionally transmitted by the heating body is accelerated, the heating and acting heat effect ratio per unit time of the tank body is effectively improved, and the power loss and the heating loss are reduced.

Description

[0001] technical field [0002] The invention belongs to the technical field of water heaters, and is an important improvement to the existing instant electric water heater heating device. Specifically, it relates to a single-tank, double-tube bidirectional electric heating device and an air energy instant water heater. And it extends to the application field of water heating and water heaters. Background technique [0003] The heating device of the instant electric water heater widely used on the market mainly adopts two kinds of electric heating heating elements of metal pipe and non-metal pipe at present. [0004] The metal tube heating element has the characteristics of high thermal efficiency, simple heating method, good water pressure resistance, low noise, high stability and durability of the whole machine, but its biggest disadvantage is that it cannot realize the true separation of water and electricity. [0005] Non-metallic tube heating elements are mostly made o...
