Description
Technical field
The utility model relates to a kind of heating element heater of quick heating type water heater, particularly a kind of quartz heating-pipe with temperature detector.
Background technology
Along with the raising of people's living standard, the more and more convenient convenience of household electrical appliance.Existing domestic hot water's machine adopts spiral or the heating of U-shaped metal tube mostly, and heating wire is installed in metal tube, and metal tube is immersed in the water, heating after energising.The electric heater of this structure, the water storage heater of a larger volume of needs, the water yield of at every turn heating up water is larger.Because each hot water can not be finished completely, in tank, can remain a small amount of water, be repeatedly heated, be unfavorable for healthy.Meanwhile, after metal tube heating, metallic can penetrate in hot water, and this type of hot water of long-term drinking is unfavorable to health.
Most scientific drinking water mode of heating is the boiling in ducts technology that adopts the heating of plated film quartz ampoule at present, heat, and cold water passes through in managing, and is heated to rapidly 90 to 100 degree in the outer plating of quartz ampoule Electric radiant Heating Film.Its heating is rapid, and only to flowing through the water of heating tube, heats, and the surplus water yield is few, does not have the problem of repeated boiling.The good insulating of quartz ampoule own, is again good heatproof container, can not ooze out any harmful metal ion during high temperature.
The quartz heating-pipe of plating Electric radiant Heating Film is very responsive to the variation of temperature, and particularly dry combustion method the most easily causes Electric radiant Heating Film to damage.Because quartz ampoule internal capacity is less, water storage is few, and when the lack of water of heating tube porch, the hot water in pipe drains rapidly, causes quartz heating-pipe dry combustion method, causes Electric radiant Heating Film to be damaged.
In order to detect the variations in temperature of quartz heating-pipe, described in patent No. CN132033734 .7 " the calandria assembly of immediately heating water heater ", water outlet at heating tube is provided with temperature detector, temperature-sensitive head contacts with hot water, on heating tube sidewall, temperature controller is installed, the temperature of delivery port and sidewall is monitored simultaneously.
But because the heat conduction of quartz ampoule own is slow, and the volume of quartz ampoule is less, once water inlet lack of water, the water in quartz ampoule can be emptying rapidly.And find heating tube because dry combustion method causes temperature significantly to rise to holding circuit and starts working when temperature detector and temperature controller; cut off heating power supply, its process meeting time delay several seconds even more than ten seconds, causes Electric radiant Heating Film to be subject to thermal shock serious; cause heat fatigue, the service life of infringement Electric radiant Heating Film.
In addition, heating tube is conventionally vertically installed, cold water inlet design below, delivery port designs up.Because the heat conduction of quartz ampoule own is slow, when quartzy inner pipe water pressure is inadequate, when water flow velocity is slower, also can produce local heating inhomogeneous, cause local Electric radiant Heating Film temperature higher, when heat is transmitted to the temperature-sensitive head of delivery port, cause Electric radiant Heating Film hot-spot impaired.
Summary of the invention
Technical problem to be solved in the utility model: provide a kind of to water temperature sensitive, homogeneous heating is with the quartz heating-pipe of temperature detector.
The technical scheme in the invention for solving the above technical problem is: a kind of quartz heating-pipe with temperature detector, at quartz ampoule outer surface, be coated with Electric radiant Heating Film, the upper end of Electric radiant Heating Film is top electrode, lower end is bottom electrode, the delivery port of quartz ampoule is arranged in holder, and temperature detector is installed on holder, and temperature detector comprises temperature detector seat and test point, it is characterized in that: between the test point of described temperature detector and Electric radiant Heating Film, have insulator, the test point of temperature detector is arranged on the relative side of Electric radiant Heating Film.
Described temperature detector is fixed in holder with back-up ring, and the test point of temperature detector contacts with the inwall of quartz ampoule, and is fixed on the corresponding quartz ampoule inwall of Electric radiant Heating Film by pressure ring.
The test point of described temperature detector is fixed on the corresponding quartz ampoule inwall of top edge of Electric radiant Heating Film by pressure ring.
Described Electric radiant Heating Film skin scribbles insulating coating, is fixed with the sensing point of temperature detector on insulating coating.
Described insulating coating aligns with the top edge of Electric radiant Heating Film.
Described Electric radiant Heating Film skin is fixed with insulating trip, is fixed with the sensing point of temperature detector on insulating trip, and insulating trip is annular, is directly enclosed within Electric radiant Heating Film and fastening, or is fixed on outside Electric radiant Heating Film with fixture.
Compared with prior art, the utility model has the advantage of: the test point of temperature detector directly contacts with the inwall of quartz ampoule, or directly contact with the upper end outer wall of Electric radiant Heating Film by insulating barrier, and the also hot water of not sum delivery port contact.While therefore there is dry combustion method, perception Electric radiant Heating Film and heating tube inwall or outer wall are overheated rapidly, thereby cut off the electricity supply rapidly, are swift in response, and can effectively protect Electric radiant Heating Film, prevent that it from burning out.And can coordinate control circuit to accurately measure coolant-temperature gage.

The specific embodiment
With a quartz heating-pipe for temperature detector, comprise quartz ampoule 1 and temperature detector 2.
On the outer wall of quartz ampoule 1, scribble Electric radiant Heating Film 12, the upper end of Electric radiant Heating Film is top electrode 11, and lower end is bottom electrode 13.Cold water enters quartz ampoule 1 from the below of electrothermal tube, and Electric radiant Heating Film, by quartz ampoule heat conduction, makes cool water heating, and hot water outlet is arranged on the top of quartz heating-pipe.
As shown in Figure 1, the outside of quartz heating-pipe is provided with shell, and top is provided with holder 4, and temperature detector seat 2 is arranged in holder 4, and by retainer ring 22, is fixed in the draw-in groove of holder.Delivery port 14 places of quartz heating-pipe 1 are provided with temperature detector 2, and temperature detector comprises temperature detector seat and test point, between the test point 21 of temperature detector and Electric radiant Heating Film 12, are provided with insulator, and the test point 21 of temperature detector is arranged on the relative side of Electric radiant Heating Film 12.
Embodiment mono-is the built-in quartz heating-pipe of test point, by quartz ampoule itself, as insulator, the test point of temperature detector 21 and Electric radiant Heating Film 12 is isolated.Test point 21 is arranged on the top of cylindrical probe, and cylindrical probe is fixed on the inwall of quartz ampoule 1 by pressure ring 3, and test point 21 is fitted on quartz ampoule inwall, and the relative position of the top edge in Electric radiant Heating Film 12.
Pressure ring 3 is an elastic metallic C shape ring, and there is a circular groove at its middle part, for holding cylindrical, pops one's head in.
The built-in quartz heating-pipe of test point described in embodiment mono-, easy for installation, easily dismounting, test point contacts with quartz ampoule tube wall with hot water simultaneously, to water temperature sensitive.Than traditional delivery port, detect water temperature and change, monitor whether dry combustion method of quartz heating-pipe, delay time, from the several seconds, is reduced to 1 to 2 second, effectively protects the Electric radiant Heating Film of quartz heating-pipe, and can coordinate control circuit accurately to measure coolant-temperature gage.
Embodiment bis-is test point external quartz heating-pipe, is coated with the exhausted insulating coating of one deck on the top of Electric radiant Heating Film 12, and insulating coating 24 is positioned at the below of top electrode 11.
