Description
Technical field
It is mainly used for being heated to water lower than steam the present invention relates to a kind of device for heating liquids, especially one kind
The device for heating liquids of state temperature.
Background technique
Generally, in needing the continuous heating electrical appliance of hot water out, package or filling by heating resistance wire by insulating layer,
It is embedded in the preferable cast aluminium of thermal coefficient, while stainless steel tube bending is formed into continuous flow channel for liquids, is embedded in cast aluminium.
Because the heat that heating resistor generates cannot directly and water carries out heat exchange, need that cast aluminium is first heated to certain temperature
It spends, the heat on cast aluminium is exchanged by stainless steel tube flow channel for liquids and aquatic products heat.Since the thermal inertia of aluminium is big, can exist following
Problem: 1, in booting, need to wait longer time 15 to 30S(seconds) preheating, cast aluminium could be heated to the temperature needed；
If the heat that heating resistance wire generates cannot keep up with the heat of liquid absorption, meeting in time 2, in the case where continuously going out hot water
The temperature of cast aluminium is caused to decline, water temperature if necessary cannot decline, and need to continue waiting for heat；If 3, heater be in
In machine, need to cause the waste of the energy with control come the temperature of constant cast aluminium；4, the cast aluminium heating with this high thermal inertia
Device, it is necessary to which the water that steady temperature is obtained by preheating, in continuous effluent, water temperature cannot be constant.Because of the inertia of high heat,
The consecutive variations for being less able to achieve water temperature are adjusted.The production technology of cast aluminium is complicated simultaneously, and volume is big, weight weight.
Based on above problem, there are some schemes to go to improve, such as do plastic liquid runner in stainless steel thick film round tube, comes
The influence of thermal inertia is avoided, plastics have certain hardness, need to be inserted in stainless steel outer tube, can easily be inserted in stainless steel
In round tube, dimensional fits need to reduce the outer diameter of plastic liquid runner, can not achieve tight fit.There is no problem for installation, but can band
The problem of sealing, cause the water cannot to flow fully according to the flow direction of flow channel for liquids, some total water can be from being not tight seal
Gap at take a shortcut, water stream channel is certain, inevitably result in a part of water and do not flow, become stagnant water, continuous heating at this,
Gasification is eventually led to, steam is generated and sprays, water outlet is intermittent, simultaneously as the intermetallic sealing of plastic casing can only be by sealing
Circle sealing can not achieve the requirement of storage pressure 8 to 10bar, in normal pressure, it is also possible to because rate or sealing ring are in the environment of high temperature
It is used for a long time and aging occurs, the risk of leakage occur.
Summary of the invention
It it is an object of the invention to overcome above-mentioned the shortcomings of the prior art, and provides a kind of simple and reasonable for structure, adds
The device for heating liquids that thermal response speed is fast, low energy consumption.
The object of the present invention is achieved like this:
A kind of device for heating liquids, main body and heater element including being cylindrical in shape structure respectively, heater element set
Outside body surfaces, heater element is made of outer tube with the heating circuit for being printed on outer tube outer surface, which is characterized in that the master
Body is made of inner tube and helix, and inner tube both ends are sealed with outer tube both ends respectively to be cooperated, and inner cavity, spiral shell are formed between outer tube and inner tube
Spin line is made of support inner core and soft set, and soft set is set in outside support inner core, and tightly spiral is wound around inner tube periphery to helix；
Helix is pressed in the inner cavity between outer tube and inner tube, wherein helix, inner and outer tubes inner wall surround spiral jointly
Fluid flow path, the upper and lower ends that main body corresponds to fluid flow path are equipped with liquid outlet channel and feed pathway.
Spiral fluid flow path defines liquid helical flow, hands over so as to do adequately heat with heater element
It changes.For the heat exchange of liquid and heater element realization large area, the contact area of body element and heater element wants sufficiently small,
The heat for guaranteeing that heater element generates passes to liquid in time, so being separated out spiral fluid flow passageway using helix
Diameter reduces helix and outer tube contact area.It can also allow on heating resistor simultaneously by the temperature of body element covering part not
Can be excessively high, it is beneficial to main body heater element.In order to which liquid flowing is smooth, spiral helicine fluid flow path is needed to have centainly
The arrangement of linear velocity and angular speed, i.e. fluid passage road needs certain tilt angle, is unlikely to form resistance on fluid passage
Power.Because specific gravity declines after heated liquid, hot liquid can always be flowed up.
The purpose of the present invention can also be solved using following technical measures:
As a more specific scheme, the outer tube and inner tube are stainless pipe, inner tube both ends respectively with outer tube two

Amount is 3.14mm*43mm*62mm*0.5mm/1000*7.9g/cm3=33.14g, and the specific heat of stainless steel is 0.49J/(g. DEG C), such as
25 DEG C of main body is heated to 85 DEG C by fruit, heats the heat of absorption are as follows: 0.49J/(g. DEG C) * 33.14g*(85-25) DEG C ≈
974J.Heating time needs: 974J/2000W ≈ 0.48S individually considers the thermal inertia of main body, it is only necessary to which 2s can temperature rise
65℃.Residual water in heating tube is 6ml=6g, if being heated to 85 DEG C from 25 DEG C, the heat of absorption are as follows: 4.2J/(g. DEG C) and *
6g*(85-25) DEG C=1512J.Heating time needs: 1512J/2000W ≈ 0.76S is needed main body and residual water temperature rise 60
DEG C time only need 0.48S+0.76=1.24S.
