Description
Technical field
This utility model relates to a kind of liquid heating, the liquid heating of a kind of band temperature-sensitive.
Background technology
Typically, in the heating electrical appliance needing to go out continuously hot water, by heating resistance wire by the parcel of insulating barrier or filling, it is embedded in the preferable cast aluminium of heat conductivity, stainless steel tube bending is formed continuous print flow channel for liquids simultaneously, be embedded in cast aluminium.
Because the heat that heating resistor produces can not directly and water carries out heat exchange need cast aluminium is first heated to uniform temperature, the heat on cast aluminium passes through stainless steel tube flow channel for liquids and the exchange of Aquatic product heat.Owing to the thermal inertia of aluminum is big, 1 can be there is problems in that, when start, need to wait longer second time 15 to 30S() preheating, cast aluminium could be heated to the temperature needed；If 2 in the case of going out hot water continuously, the heat that heating resistance wire produces can not catch up with the heat that liquid absorbs in time, and the temperature of cast aluminium can be caused to decline, if the water temperature needed can not decline, needs to continue waiting for heating；If 3 heaters be in standby in, needs control come constant cast aluminium temperature, cause the waste of the energy；4, with the cast aluminum heaters of this high thermal inertia, it is necessary to obtained the water of steady temperature by preheating, when continuous effluent, water temperature can not be constant.Because the inertia of high heat, the consecutive variations regulation of water temperature more can not be realized.The complex manufacturing of cast aluminium simultaneously, volume is big, Heavy Weight.
Based on above problem, some schemes are had to go to improve, as done plastic liquid runner in rustless steel thick film pipe, avoid the impact of thermal inertia, plastics have certain hardness, need to be inserted in rustless steel outer tube, it is possible to be easily inserted in stainless pipe, dimensional fits needs to reduce the external diameter of plastic liquid runner, it is impossible to realize tight fit.It is no problem to install, but the problem that sealing can be brought, cause water can not flow fully according to the flow direction of flow channel for liquids, some water total can be taken a shortcut at poorly sealed real gap, water stream channel is certain, inevitably result in a part of water not flow, become stagnant water, continuous heating in this place, ultimately result in gasification, generation steam sprays, water outlet is intermittent, simultaneously as the intermetallic sealing of plastic casing can only rely on sealing ring to seal, the requirement of storage pressure 8 to 10bar can not be realized, in normal pressure, it is likely to because speed or sealing ring occur aging at the environment life-time service of high temperature, the risk of leakage occurs.
At present, in purifier field, such as: traditional water purifier, being the most only provided with filtering area and equalizing section, during use, after water is first filtered, heated or cooling directly output is available for the water that user drinks；But, the water purifier of above-mentioned traditional structure, still suffer from following weak point: (1) is at different use environment, often affected by different inflow temperatures, there is notable difference in the leaving water temperature that user drinks, such as: winter and summer, and water is heated or freezes the identical time, but owing to inflow temperature is different, its leaving water temperature is clearly present difference；For this, also there is partially purifying water machine, for adapting to inflow temperature Different Effects, scalable heating or the regulatory function of cooling time length can be set, although this can meet user's requirement to leaving water temperature to a certain extent, but use to user and cause inconvenience, especially cannot meet the high-end user use needs to Quick water exit, therefore, how in purifier field, on the premise of not changing heating or cooling time, can guarantee that again leaving water temperature can meet user and drink requirement, this is always the technical barrier that industry is badly in need of solving.
