Embodiment Construction

[0035] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0036] The present invention takes a double-layer round tube 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 tube body and theoretically more layers. Similarly, the heating element The space layer will 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 be given different power, that is, multiple heating working modes. Of course, the use of three-layer pipe water flow channels and multi-mode heating in a single tank will achieve a good heating effect, while the practical significance of more than three pipe water flow channels is very low.

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

Technical field [0001] 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 extended to the application field of plumbing water heater. Background technique [0002] At present, the heating devices of instant electric water heaters that are widely used in the market mainly adopt two electric heating elements: metal pipes and non-metal pipes. [0003] 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 separation of water and electricity in the true sense. [0004] Non-metallic tube heating elements are mostly made of crystal, glass, and cerami...
