Abstract
The utility model discloses an electronic water heater. The electronic water heater comprises a main body housing; a liner is arranged in the interior of the main body housing; a heat insulation layer is arranged between the liner and the main body housing; and the outer side of the liner is wound by a self temperature limit heat tracing belt. According to the utility model, the outer side of the liner is wound by the self temperature limit heat tracing belt, so by electrifying the self temperature limit heat tracing belt, it can be achieved that water in the liner is heated. The self temperature limit heat tracing belt is characterized in that the resistance of the heat tracing belt increases along with the rising of temperature, and when the temperature rises to a certain degree, the resistance of the heat tracing belt is so big that current can be cut off, so the temperature rises to the upper limit and will not rise any more. Thus, when the temperature rises to a certain degree, the resistance of the heat tracing belt will cut off the electrified current, and temperature will not continue to rise, so a problem is solved that heating temperature of an electric heating pipe of an electronic device of a current electronic heater cannot be effectively controlled.

The purpose of this utility model is to provide a kind of electric heater, can effectively control the heating-up temperature of electric heater to water.
For solving the problems of the technologies described above, the utility model provides a kind of electric heater, comprising:
Main body cover;
The inside of described main body cover is provided with inner bag; Between described inner bag and described main body cover, be provided with heat-insulation layer;
The outside of described inner bag, is wound around and is provided with self-limiting heating cable.
Preferably, described main body cover comprises:
The first housing and the second housing;
Described the first case lid is combined on described the second housing.
Preferably, the top of described main body cover is provided with the first water nozzle; Described the first water nozzle is connected with the top of described inner bag;
The bottom of described main body cover is provided with the second water nozzle; Described the second water nozzle is connected with the bottom of described inner bag.
Preferably, also comprise:
Power interface;
Described power interface is connected with described self-limiting heating cable.
Above-mentioned background technology relatively, electric heater provided by the utility model, is equipped with self-limiting heating cable in the outer felt winding of water heater liner, by self-limiting heating cable energising, to realize, the water in inner bag is heated.Self-limiting heating cable has, the characteristic that the rising of heating tape electrical resistance temperature increases, and in the time that temperature acquires a certain degree, heating tape resistance is large to blocking electric current, and temperature just reaches the upper limit and no longer raises.So, the electric heater that the utility model provides, in the time that temperature is heated to a certain degree, the resistance of self-limiting heating cable will be blocked electrical current, no longer continue to heat up, can not effectively control the problem of electrothermal tube heating-up temperature thereby the electronic instrument that has solved existing electric heater very easily breaks down.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of a kind of electric heater of the utility model.
The specific embodiment
In order to make those skilled in the art person understand better the utility model scheme, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 1, Fig. 1 is the structural representation of a kind of electric heater of the utility model.
In the specific embodiment, electric heater provided by the utility model, comprises main body cover 001, heat-insulation layer 102, inner bag 105 and self-limiting heating cable 107;
Described inner bag 105 is arranged on the inside of described main body cover 001, between described inner bag 105 and described main body cover 001, has been filled with heat-insulation layer 102; Described self-limiting heating cable 107 uniform winding are in the outside of described inner bag 105.
Self-limiting heating cable is the banded tracing heating of being made up of the high polymer conductive composite with positive temperature coefficient (positive temperature coefficient, PTC) electrical resistivity property.Heating tape electrical resistance temperature raises and increases, and in the time that temperature reaches certain numerical value, the resistance of heating tape arrives high resistance area, and resistance is large, and to almost blocking electric current, temperature just reaches ceiling value, no longer raises, and plays the effect of automatic temp limit.
The electric heater that the utility model provides, the characteristic of utilizing self-limiting heating cable 107 electrical resistance temperature to raise, switches on to self-limiting heating cable 107, by self-limiting heating cable 107, the water in inner bag 105 is heated.
In the utility model, using self-limiting heating cable 107 as electrical heating elements, closely be wrapped in uniformly the outside of inner bag 105, cold water in homogeneous heating inner bag 105, prescribe a time limit when the water in inner bag 105 is heated to the upper of self-limiting heating cable 107 operating temperatures, self-limiting heating cable 107 resistance increase to the heating of blocking-up current stops.
The electric heater that the utility model provides, main body cover 001 is made up of the first housing 101 and the second housing 103, described the first housing 101 covers on described the second housing 103, in the process of the described electric heater of assembling, first inner bag 105 is placed on to the second housing 103 inside, filling heat insulating wall 102 between inner bag 105 and the second housing 103, then covers the first housing 101 on the second housing 103 simultaneously.In the utility model, the same heat-insulation layer that is provided with between the first housing 101 and inner bag 105.
In addition, in the electric heater that the utility model provides, the first housing 101 and the second housing 103 can be integral type structure, in the time of assembling, directly inner bag 105 and heat-insulation layer 102 are encapsulated in main body cover 001.From another angle, in the electric heater that the utility model provides, main body cover 001 can also be three part-structures, in top and the bottom of the second housing, outer end lid is all set, thereby more convenient to install.
More specifically, the electric heater that the utility model provides, the top of described main body cover 001 is provided with the first water nozzle 106; Described the first water nozzle is connected with the top of described inner bag 105;
