Abstract
The utility model relates to a liquid heater, which comprises an electric heating device for heating liquid, an internal-threaded pipe fitting and an external-threaded pipe fitting. An assembling opening of the external-threaded pipe fitting is arranged at one end of the internal-threaded pipe fitting, the external-threaded pipe fitting is screwed in the internal-threaded pipe fitting through the assembling opening, and a flow channel for the liquid to flow is defined by internal threads and external threads. A flow channel for the liquid is achieved through a simple thread screwing structure, thereby being simple in structure and low in cost. Threaded connection is good in sealing performance, and mixing of water among adjacent water channels of the flow channel is not easy to occur. In addition, when scale exists in the flow channel, users just need to unscrew the external-threaded pipe fitting to perform washing, thereby being very convenient to disassemble and wash. Simultaneously, due to the fact that the structure of spiral teeth of the threads is stable and not easy to deform, the sealing performance of the flow channel can also be effectively guaranteed after many times of disassembly and washing.
Description
Technical field
The utility model relates to the machine for kitchen use technical field, relates in particular to a kind of liquid heater.
Background technology
Existing household drinker, water heater mainly are divided into heat storage type and Instant heating type two kinds.
The heat storage type water dispenser comprises the heating inner bag, and water is positioned at for a long time and heats inner bag, and it is more to cause the interior incrustation scale of heating inner bag to condense on the one hand, and the thermal efficiency is lower, heats the interior water-cooled of inner bag on the one hand but in addition, will heat in the time of need drinking again, and causes a large amount of wastes of the energy.
For overcoming the deficiency of heat storage type water dispenser, instant heating type drinking machine has appearred on the market.This instant heating type drinking machine comprises liquid heater, and this liquid heater generally includes the water flow passage that sealing forms, and when causing the inner formation of its water flow passage incrustation scale, disassembly, cleaning are difficulty comparatively.And often dismounting can cause the sealing property of water flow passage to descend; Cause the water capacity in the adjacent water channel to be prone to mix, influence the temperature of water, water burns not open or does not reach the temperature of needs; Drink or use and influence the daily of people; Even drainage can take place, and damage other electronic device, bring Danger Electric shock risk.Rinse water is not dirty for a long time, and gathering of incrustation scale is prone to cause dry combustion method danger again.
The utility model content
In view of this, be necessary to provide a kind of thermal efficiency high, easily removable and washable liquid heater.
The utility model is realized through following technical scheme:
A kind of liquid heater; The electric calorifie installation, internal thread tube piece and the male element that comprise heating liquid; One end of this internal thread tube piece offers the installation opening of male element, and male element screws in internal thread tube piece through installation opening, and internal and external screw thread surrounds the runner of liquid flow.
Said internal thread tube piece is provided with capping with respect to an other end of installation opening.
Said liquid heater also comprises seal cover that is arranged on corresponding installation opening on the male element and the sealing ring that is arranged on the internal thread tube piece installation opening, and seal cover is replaced sealing ring.
Said capping is fixedly connected with internal thread tube piece with internal thread tube piece integral production or capping.
The flight pitch of said internal and external screw thread equates, and the ratio of the thread thickness of internal and external screw thread and flight pitch is less than 2:3.
Said electric calorifie installation comprises the electrothermal tube that is arranged in the male element.
Said electric calorifie installation comprises around internal thread tube piece outside electromagnetic heater or thick film heater.
Said liquid heater also comprises temperature controller, and this temperature controller is arranged on the seal cover of outside and/or male element of internal thread tube piece.
