Abstract

The utility model relates to a fully-automatic electric water-boiling utensil, comprising a cup body and an outer shell. The exterior of the side wall of the lower part of the cup body is coated with an electric heating film. A power socket is arranged on the shell body. The exterior of the bottom of the shell body is provided with a gravity switch. The outer wall of the cup body is also provided with an automatic reset type thermostat. The automatic reset type thermostat of the outer wall of the cup body is arranged on the cup bottom. The water-boiling utensil of the utility model uses the gravity switch to replace the dry burning prevention electrode which is arranged on the inner wall of the cup body, and has the advantages of simple structure and effective operation.

Description

Fully automatic electric boiling water tool

The utility model belongs to the electric heating glassware for drinking water.

The measure of existing electric boiling water tool anti-dry is that pair of electrodes is installed in cup inwall appropriate location, utilizes the water conduction that operating circuit is connected.Water level falls, and makes the electrode outage of surfacing, and makes the operating circuit cut-out.It is just malfunctioning that its shortcoming is that in a single day electrode ties incrustation scale.In addition, the technology that electrode is set at the cup inwall is very complicated, increases product cost.

The purpose of this utility model is to propose a kind of fully automatic electric boiling water tool technical scheme, the anti-dry heating electrode that cancellation cup inwall is provided with.

The utility model fully automatic electric boiling water tool comprises cup, shell, and the cup lower sides applies Electric radiant Heating Film outward, and supply socket is located on the housing, at housing bottom peripheral hardware gravity switch.Also can be provided with the formula temperature controller that automatically resets at the cup outer wall.The formula that the automatically resets temperature controller of cup outer wall is located at a glass bottom.

Embodiment of the present utility model is as shown in drawings:

Accompanying drawing is that the master of the utility model boiling water tool looks the part section diagrammatic sketch.

Number in the figure is represented:

1, loam cake, 2, cup, 3, shell, 4, combined type temperature controller automatically, 5, gravity switch, 6, the switch push rod, 7, socket, 8, heat-preservation cotton, 9, Electric radiant Heating Film.

Accompanying drawing is specified the utility model in conjunction with the embodiments:

Cup 2 bottoms of the design's boiling water tool place shell 3, and Electric radiant Heating Film 9 covers the cup outside in the enclosure, covers heat-preservation cotton 8 outward.Be connected with gravity switch 5 and temperature controller 4 in the electric heating operating circuit.Gravity switch 5 is by switch push rod 6 control, and push rod 6 is enclosed within the spring, when cup great during in spring force push rod 6 displacements make switch 5 be in the position of connecting operating circuit.Cup heavily alleviates to less than spring force the time push rod 6 cut-out operating circuit that resets.When the water in the cup was less than set amount, operating circuit cut off, and prevents from automatically to dryout or dry combustion method.It is 100 ℃ that temperature controller 4 is set the outage water temperature, and the energising water temperature is 85 ℃; Operating circuit cut off when water boiled, and the operating circuit startup was heated when water temperature was lower than 85 ℃.Supply socket 7 is located at shell 3 bottoms.Operating circuit of the present utility model belongs to simple known technology.

The utility model water-boiling utensil has replaced with gravity switch is located at the anti-dried of glass inwall Burn electrode, have simple structure, the effective advantage of working.

Claims
