Abstract
The present invention relates to an electric heating liquid container which comprises a heating disk (2), an electric heating component (3) and a temperature controller (4), wherein the heating disk (2) is positioned on the bottom and is horizontally arranged; the electric heating component (3) and the temperature controller (4) are arranged on the heating disk (2), and contact the heating disk (2) in the heat conducting mode. The present invention is characterized in that the temperature controller (4) is arranged in the midpoint point which is close to the electric heating component (3); the temperature controller (4) can be provided with only one thermosensitive component (41), and is preferably provided with two thermosensitive components (41) which are arranged in adjacent positions; in addition, the two thermosensitive components (41) are arranged on the temperature controller (4) in the mode that tails are opposite and heads face outwards, and are respectively arranged on both sides of the medial axis of the electric heating component (3). Compared with the prior art, the present invention slickly makes use of the principle of the change of gradient of temperature generated on an electric heating disc to arrange the temperature controller in the position with the maximal temperature on the electric heating disc; thus, once part of the electric heating liquid container is burnt to be dry because the electric heating liquid container is oblique, the electric heating liquid container can sense the condition and act in time. On one hand, that the adjacent and symmetrical thermosensitive components are arranged on the temperature controller enhances the inductive capacity of the temperature controller; on the other hand, that the adjacent and symmetrical thermosensitive components are arranged on the temperature controller reduces the volume of the temperature controller; the temperature controller is universal in electric heating liquid containers with various.
Description
Technical field
The present invention relates to a kind of electric-heating liquid container and temperature controller thereof that liquid in container is heated with heating.
Background technology
Existing electric-heating liquid container comprises electric kettle, small household appliances such as coffee pot, usually, include the flat underside of a metal material, heating is arranged under the base plate, the electric energy that the electric loop of automatic disconnection heating or minimizing are delivered to heating when liquid in the container is dryouied, also be provided with temperature controller, it is heat conduction with heating and contacts, generally comprise a thermoswitch, be installed in and be positioned on container bottom and the horizontally disposed heat-generating disc, its action can be opened to one group of contact of electric heating vessel power supply, and common thermoswitch adopts bimetallic actuator as temperature-sensitive element.
Temperature controller in the previous electric-heating liquid container has only a thermoswitch, it brings a problem in the use to be, electric-heating liquid container is when heating work, inadvertently prevented terminating on the non-level surface sometimes, cause the base plate and the heat-generating disc of its container to tilt, make the part on the base plate still have water to cover, but the anhydrous covering of other part and cause the heating dry combustion method, when if this moment, temperature controller just in time was configured on the base plate that still has the water covering, but disconnecting circuit can not work, thereby cause heating to damage because of local dry burning is overheated, serious even can cause fire incident.For this reason, publication number provides a kind of electric-heating liquid container that the temperature controller of two thermoswitches of tool is housed for the Chinese invention patent application of CN1154781A, by with the temperature of two thermoswitch settings separated by a distance, thereby prevent the generation of said circumstances with two diverse locations on the perception base plate.Yet this design still can only prevent the local dry burning that container produces when the direction of two thermoswitch lines tilts, and when container when the vertical direction of two thermoswitch lines tilts, still have above-mentioned local dry burning phenomenon and take place.On the other hand, because this design is with two thermoswitch settings separated by a distance, certainly will cause the volume of temperature controller to become big, and different electric-heating liquid containers has the floor of different sizes, for making temperature controller work in optimum state, also certainly will produce the temperature controller of a series of different size sizes, this is unfavorable for suitability for industrialized production undoubtedly.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of container that can effectively prevent to cause the hot liquid container and the temperature controller thereof of local dry burning because of the inclination of different angles at above-mentioned prior art present situation.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: electric-heating liquid container comprises that one is positioned at bottom and horizontally disposed heat-generating disc, and be arranged on the heat-generating disc and the heating and the temperature controller of heat conduction contact with it, described temperature controller is arranged on the position of the mid point of contiguous described heating, it is characterized in that, described temperature controller has the temperature-sensitive element that two next-door neighbours are provided with,, head relative with afterbody is arranged on the temperature controller towards outer mode, and the both sides of the axis of the described heating in office.
It is circular-arc that described heating can be, and also can be other shapes;
Compared with prior art, the present invention has utilized heating to produce the graded principle of temperature dexterously on electric hot tray, temperature controller is arranged on the point midway of contiguous heating, just temperature controller is arranged on the highest position of electric hot tray temperature, like this, in case the heating local dry burning takes place because of inclination in electric-heating liquid container, just perception and action in time, and be provided with adjacent on the temperature controller, the temperature-sensitive element of symmetry, strengthened the sensing capability of temperature controller on the one hand, the volume of temperature controller is reduced, and be common to the electric-heating liquid container of various sizes.

The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, electric-heating liquid container comprises that kettle body 1 and is positioned at bottom and horizontally disposed heat-generating disc 2, and be arranged on the heat-generating disc 2 and the circular arc heating 3 and the temperature controller 4 of heat conduction contact with it, described temperature controller 4 have two afterbodys relatively, head dashes the outer temperature-sensitive element 41 that is provided with, referring to Fig. 2, Fig. 3, and be close to the position of the mid point of the contiguous described heatings 3 of heat-generating disc 2, and make two temperature-sensitive elements stride the both sides of heating 3 axis in 41 minutes, referring to Fig. 2, Fig. 4.5 is 360 degree rotary electrical connectors among Fig. 1.
Certainly, described temperature controller 4 can be reduced to one with its temperature-sensitive element 41, at this moment, should be positioned on heating 3 axis with this temperature-sensitive element 41.
If heating 3 local dry burning take place because of tilt (whichever direction) in electric-heating liquid container, then heat-generating disc 2 at first heats up at the position (also being the dashed area among Fig. 4, Fig. 5) of contiguous heating 3, at this moment, temperature-sensitive element 41 then just in time is in its central part, with the rising of sense temperature at once and make temperature controller 4 disconnect the power circuit of heatings 3, thereby ensure safety.
