Abstract

The utility model relates to an electrothermal liquid container which comprises a heating disc (2) which is arranged at the bottom and is horizontally arranged, an electrothermal element (3) which is arranged on the heating disc and is contacted with the heating disc in a heat conducting way, and a thermostat (4). The utility model is characterized in that the thermostat (4) is arranged at the midpoint of the adjacent electrothermal element (3); the thermostat (4) can be provided with only one thermosensitive element (41) but better modes are that the thermostat (4) is provided with two thermosensitive elements (41) which are tightly adjacent to each other; the two thermosensitive elements (41) are arranged on the thermostat (4) in a way that the tails are relative and the heads face outsides and are respectively arranged on both sides of an axle wire of the electrothermal element (3). The utility model slickly makes use of the principle the electrothermal element can create gradient change of temperature on an electrothermal disc and the thermostat is arranged at a highest position of the temperature of the electrothermal disc. In this way, once parts of the electrothermal element are burned in a dry way because the electrothermal liquid container is tilted, the utility model can sense the situation and do actions in time. The thermostat is provided with contiguous and symmetrical thermosensitive elements, which enhances the sensing ability of the thermostat on one hand and causes the volume of the thermostat to be reduced on the other hand. The utility model is suitable for electrothermal liquid containers with various sizes.

Description

A kind of electric-heating liquid container and temperature controller thereof

Technical field

The utility model 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 in the utility model 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 utility model 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, it is characterized in that described temperature controller is arranged on the position of the mid point of contiguous described heating.

It is circular-arc that described heating can be, and also can be other shapes;

Described temperature controller can have only a temperature-sensitive element, but better, is to have the temperature-sensitive element that two next-door neighbours are provided with, and, 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.

Compared with prior art, the utility model 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 utility model 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.
