Embodiment Construction

[0024] The specific implementation manner of the present invention will be further described below in conjunction with the accompanying drawings.

[0025] refer to figure 1 , this embodiment proposes a direct heating heater, including:

[0026] The direct heating heater housing 1, the heating device 2 arranged inside the direct heating heater housing 1 and the direct heating heater components;

[0027] At least one section of the heating device 2 is equipped with a metal elastic device 3 , and the inner wall of the direct heating heater shell 1 corresponding to the heating device 2 without the metal elastic device 3 is partially or completely provided with a spiral groove structure 4 .

[0028] In the prior art, the water flow quickly passes through the cavity formed by the ceramic heating tube and the shell of the heater, and the heat energy is directly transferred from the ceramic heating tube to the flowing water. Due to the relatively low heat dissipation capacity of the ...

Abstract

The invention discloses a direct-heat-type heater. The direct-heat-type heater comprises a direct-heat-type heater shell, a heating device arranged in the direct-heat-type heater shell and a direct-heat-type heater part. At least one section of the heating device is additionally provided with a metal elastic device, and the inner wall, corresponding to the portion, not additionally provided with the metal elastic devices, of the heating device, of the direct-heat-type heater shell is partially or wholly provided with spiral groove structures. The problems that in the prior art, the ceramic heat dissipation ability is relatively low, and consequently, the heat transfer efficiency is low is solved, and the problem that water quickly passes through the heater and cannot be fully and uniformlymixed, and consequently, the water temperature is not uniform is also solved.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a direct heating heater. Background technique [0002] In the current structure of the direct heating heater, the water flow directly passes through the cavity formed by the ceramic heating tube and the shell of the heater. The ceramic tube and the inner wall of the shell are smooth surfaces without other auxiliary structures, so the water flow directly and quickly passes through the cavity. The heat energy is directly transferred to the running water by the ceramic heat pipe, and the heat transfer efficiency is low due to the relatively low heat dissipation capacity of the ceramic. [0003] Since the water passes through the heater very quickly, the water cannot be mixed evenly enough to cause uneven water temperature. In current heater products, a small water mixing tank device is usually installed on the water path at the back end of the direct heating heater to solve the problem of une...
