Description
Technical field
The present invention relates to field of sanitary equipment, and in particular to a kind of for the leakproof electrical connector of electric heating floor and its life
Production. art.
Background technology
At home, especially In Middle And Lower Reaches of Changjiang River, non-heating zone is listed in, but these regional winters are clammy tight
Weight, particularly indoors, indoor environment cool, damp are more painful than the north that cold is dried, with expanding economy,
The indoor heating demand of non-heating zone is fast-developing, and has formd a potential, huge market, as people live
Horizontal raising, for indoor heating by as auxiliary facility important in the resident's living environment of heating zone is taken, building energy conservation is current
The hot issue of world's common concern, and a dose necessary of Building technology progress, wherein being supplied by heating flooring radiation
Warm mode, with its excellent thermal comfort, good sanitary condition and efficient using energy source, it is considered to be not only saved but also ring
The heating system of guarantor, at present electric heating floor mainly include following four type：
First, heating cable electric heating floor
Nowadays the heating cable electric heating floor of in the market have singly lead and it is double lead two kinds, most of if general family expenses is all from double
Conductive heating floor, and from being mounted so as in situation, the installation of double conductive heating floors is simpler, more preferably designs, and terminates
Time-division where can.It is a kind of electric heating floor nowadays with the most use, if fraternity bigger inside family uses
To single conductive heating floor, because the fluctuating that it radiates is wider, each nook of family can be allowed exuberant warm.
2nd, electrothermal film electric heating floor
The temperature-controlling system of electrothermal film electric heating floor is by Electric radiant Heating Film, linking card, link wire, thermostat, insulation auxiliary material, thermal insulating material
What material was formed.From its name it is seen that Electric radiant Heating Film is its heater element, after heater element link electricity, negative pole
Voltage difference occurs with positive pole, carbon molecules crystal generates heat in conflicting and colliding with and far infrared light wave occurs, by far-red light ripple
Reception and registration occur convection current presentation have the function that heating.90 flat house electricity electric heating floors need with 10 degree of electricity per hour.
3rd, carbon crystal electrothermo floor
Carbon crystal electrothermo floor is identical with Electric radiant Heating Film and is made up of several parts, mainly there is temperature controller, Insulating board and carbon crystal
Heating board, carbon crystal heating board are equally to act on that heat occurs by colliding with for carbon crystal molecule with electric power.This electric heating floor
Nowadays people is fewer, and for relatively other electric heating floor, its more power consumption, together its conductive force is not pole
Good, room will be held successfully long just can be warm, to consume 12 degree of electricity when this electric heating floor 100 is flat.
4th, core floor is warmed up
Warm core floor is a kind of new-type electric heating floor, and it, which has perfectly been incorporated in electric heating floor and floor, together becomes newly
Heating system, the category that it is used is also very wide, is not only in household again, or even is that space flight, science and technology can be used, and saves
Energy, environmental protection, low-carbon.It also has warm core self-heating floor and two, temperature control self-heating floor call in electric heating floor occupation.
Considered by power consumption, heating effect and security each side, what existing market was best suitable for is that cable adds
The heating system of heating floor finally spreads floor, cable and electricity, it is necessary to, then spread heating film by cable laying on the ground
Source line is attached, and temperature is controlled by the controller being connected with power line, and the junction of cable and power line is adopted at present
With plastic packaging, and the position is usually located at floor edge, and in the moist environment in the middle and lower reach of Yangtze River, junction easily makes moist, always
Change and produce leaky, while certain point damage electric leakage also occurs after having used long or because external force is destroyed in cable,
Easily cause fire or human body is damaged, potential safety hazard be present.
