Description

Pressureless heating structure capable of stably outputting boiling point high-temperature liquid Technical Field The invention mainly relates to the technical field of liquid supply systems of rapid water boilers, in particular to a pressureless heating structure capable of stably outputting high-temperature liquid with boiling point. Background The existing high-temperature liquid heating structure mostly adopts an indirect temperature control mode of 'temperature sensor+heating power adjustment', and the heating intensity is adjusted by feedback after the sensor detects the liquid temperature. This approach has significant hysteresis and is susceptible to variations in liquid flow rate and thermal inertia of the heater, resulting in large output liquid temperature fluctuations. The prior art also has the technical problem of insufficient flow stability, and the output flow of the traditional structure is mostly dependent on the rated power of the liquid inlet pump or the passive control of the cavity pressure difference, and is lack of linkage with the heating process. When the heating energy input is stable, the output flow is possibly neglected due to uneven vaporization of liquid and pressure fluctuation in the cavity, and continuous and stable quantitative output cannot be realized. Most of the technologies need to adjust the flow through additional flow valves, variable frequency liquid inlet pumps and other auxiliary devices, so that the structural complexity is increased, and the problem of adjustment lag is solved. And the direct linear correlation of heating power and flow cannot be realized, accurate flow control according to needs is difficult to achieve, and residual pressure or waste heat in a cavity is easy to occur after heating is stopped, so that the phenomenon of continuous outflow of residual liquid occurs. Disclosure of Invention The invention aims to solve the technical problem of providing a pressureless heating structure capable of stably outputting high-temperature liquid with boiling point, and overcomes the defects and shortcomings in the prior art. In order to achieve the aim, the pressureless heating structure capable of stably outputting high-temperature boiling point liquid is characterized by comprising a heating cavity, wherein a heating body is arranged in the heating cavity, a liquid inlet is formed in the position, close to the bottom, of the heating cavity, an overflow upper edge is formed in one side of the upper end of the heating cavity, a separation buffer cavity is formed in the outer side of the overflow upper edge, a liquid outlet is formed in the lower portion of the separation buffer cavity, an initial liquid level line and a boiling liquid level line are formed in the upper portion of the heating cavity, the boiling liquid level line is located above the initial liquid level line, the initial liquid level line is located below the overflow upper edge, the boiling liquid level line is located above the overflow upper edge, and the heating cavity and the separation buffer cavity are communicated with the outside atmosphere. The invention has the advantages that 1, the liquid outlet temperature of the structure is determined by the physical boiling point of liquid, the liquid is not boiled and vaporized, the liquid mixed by gas and liquid cannot pass over the upper edge opening of a heating cavity, so that the liquid outlet temperature is constant, 2, the output flow of high-temperature liquid is stable and sustainable when heating energy is stably input, 3, the output of the high-temperature liquid of the structure is always pressureless and safe when the whole structure is operated by controlling the input height of heating energy under the condition that the supply condition of low-temperature liquid is constant, the flow is controllable, and the output of the high-temperature liquid is stopped when heating is stopped.
