Description

The heating wire heating installation

Technical field

The utility model relates to the heating installation field, specifically is a kind of heating wire heating installation that is provided with thermal protector.

Background technology

The heating system of present most of house dwelling house mainly adopts air-conditioner, household warming, plumbing pipe, electricity to be inlaid into modes such as formula heating.These heating systems all need place or space to install, and use inconvenience, and it is slow to heat up.

In recent years, along with the progress of science and technology, people brought into use the heating wire heating system.Traditional relatively heating system, heating wire heating system have not water consumption, do not take up an area of, energy-saving material-saving, easy-to-install advantage, have vast potential for future development.Existing heating wire heating system generally is made up of parts such as heating wire, temperature controller and temperature sensors.In use, heated by temperature controller control heating wire, temperature sensor detects heating-up temperature and feeds back on the temperature controller, also can prevent because the too high initiation security incident of heating wire heating-up temperature simultaneously.But, because the cost of temperature sensor is higher, therefore in the heating wire heating system, negligible amounts is set, mainly be arranged in several fixed positions, can't detect all electrical heating zones, occur owing to user's covering and heat insulating article (for example piling up cotton, carton etc.) easily, cause heating-up temperature too high and cause the phenomenon of accidents such as fire in the position that temperature sensor not have to cover.For solving a last problem, the technical staff adopts the mode that increases the temperature sensor distributed quantity, but because the cost of temperature sensor is higher, so this method is not suitable for actual production.

Summary of the invention

The purpose of this utility model is to provide a kind of heating wire heating installation; it is by being provided with a plurality of thermal protectors, can realize that temperature upper limit controls automatically to the heating wire of the diverse location of heating wire heating system, prevents the potential safety hazard of the too high initiation of heating wire heating-up temperature; cost is low, is easy to install.

The utility model for achieving the above object; be achieved through the following technical solutions: the heating wire heating installation; comprise temperature controller and a plurality of heating wire heat supplies unit; heating wire supply line and electric supply installation are installed on the temperature controller; a plurality of heating wire heat supplies unit that is connected in parallel in the heating wire supply line, each heating wire heat supply unit is made up of the heating wire that is connected in series and at least one thermal protector.

Temperature sense probe line is installed on the described temperature controller, temperature sense probe is installed on the temperature sense probe line.

Heating wire stand-by power supply circuit is set on the described temperature controller, and heating wire stand-by power supply circuit is connected with circuit output end with the circuit input end of each heating wire heat supply unit respectively.

The beneficial effects of the utility model are: can solve the deficiency that exists in the known technology; By use that a plurality of thermal protectors are connected with single heating wire, utilize thermal protector that the actual heating-up temperature of heating wire is detected, when detected temperatures is higher than the thermal protector trip temperature of setting, thermal protector cuts off the power supply automatically, prevent security incident, the security that has improved the heating wire heating system owing to the too high initiation of heating wire heating-up temperature; Integral body is initiatively protection, need not artificial control, guarantees safe in utilization; Because for being connected in parallel, therefore when wherein one or several heating wire heating-up temperatures are too high when causing thermal protector to open circuit, other heating wires still can carry out heating, guarantee the continuity that heats between each heating wire; Easy for installation, be easy to use; The thermal protector cost is very low, and use in enormous quantities can not cause the cost of heating wire heating installation significantly to improve.

By increasing additional technical feature, the further advantage of the utility model is: have thermal protector and temperature sense probe duplicate protection, further improve the security of using; Be provided with heating wire stand-by power supply circuit, can be when heating wire supply line go wrong, utilize standby heating wire supply line to power, guarantee the continuous use of heating wire heating system, improve service life, for ease of maintenaince etc.
