Abstract

The utility model belongs to a cooking utensil, composed of a kettle, an electric heater and a power socket. The utility model is characterized in that the electric heater is fixed in the kettle cover; the power socket is arranged on the kettle cover; both ends of the electric heating wire in the U-shaped pipe of the electric heater are respectively connected with a temperature control switch, wherein, the temperature control switch uses the bimetallic strip heated to expand to turn over, and the top-pressure porcelain ejector rod pushes away the moving plate to cut off the power to achieve automatic temperature control. The electric heating kettle overcomes the leakage of the kettle bottom and is easy for decoration, to achieve a kettle with multi-function. The utility model can not only be heated by power, but also be heated by ingle or the gas cooking stove.

Description

Automatic electric temp. controlling kettle

The utility model belongs to the utensil of cooking utensil one usefulness to boil water.

Existing electric kettle generally all is equipped with a heater in the bottom of aluminium kettle, stainless steel or Enamel kettle, for example CN242332＜temperature self-controlled electric kettle〉heater element is placed on the bottom of kettle, its control element, supply socket all are contained on the chassis of kettle bottom, the fixed leg of chassis by screw is arranged in 3 be connected at the bottom of the kettle in aggregates.Its shortcoming is need make a call to three holes at the bottom of (1) kettle, is to be connected with screw with the chassis at the bottom of the kettle, because long-term the use is easy to occur seepage and breaks down.(2) heater element is fixed on Hu Dishang, repairs, installs, dismantles all inconvenient.(3) only suitable electricity consumption boils water, and can not use coal stove or gas kitchen ranges.

The purpose of this utility model designs a kind of new-type electric kettle, and it is convenient to have solved at the bottom of the kettle seepage and finishing, many usefulness of a kettle simultaneously, and not only available electrical heating also can use the heating of coal stove or gas kitchen ranges to boil water.

The utility model be achieved in that with the existing electric heater unit that is positioned at the bottom of the kettle all be retrofitted in pot lid below, supply socket changed system into is suitable as the Miniature Power Unit socket that pot lid is carried button, it is that supply socket is again that pot lid is carried button.

Below in conjunction with drawings and Examples the utility model is specified.

Fig. 1 the utility model structural representation

Fig. 2 temperature control switch shaft side figure

Fig. 3 temperature control switch A-A profile

Referring to Fig. 1 as can be known the utility model be a kind of temperature self-controlled electric kettle of usefulness to boil water, form by kettle (1), electric heater (2), supply socket (3), it is characterized in that electric heater is fixed in the pot lid (4), supply socket is installed on the pot lid, and heating wire (6) two ends in the U type pipe (5) of electric heater respectively are connected to temperature control switch (7).

Electric heater of the present utility model is to change existing garden shape Electrothermal ring into the U-shaped Electrothermal ring, at refractory material separation layers (9) such as U type metal tube liner one asbestos or glass fibre sleeves, heating wire is contained in the pipe, and the U-shaped mouth of pipe has an insulated enclosure rubber cushion (10).

Referring to Fig. 2, the temperature control switch housing is a garden cylindrical body, is fastened by left ogive (11), right ogive (12) and forms, and the centre is placed with a porcelain dividing plate (13), have aperture (14) in the middle of the porcelain dividing plate, porcelain push rod (15) passes this hole and contacts with moving plate (16); Left side ogive is equipped with stator (17) and moving plate, adorns a rectangle bimetal leaf (18) in the right ogive.The stator of temperature control switch is connected with heating wire, and moving plate is connected with supply socket conductive head (8).

After heating, the bimetal leaf expanded by heating, it transfers gradually by outwardly-bent that to curve inwardly be bimetal leaf upset (shown in Fig. 3 dotted line).At this moment, the porcelain push rod backs down moving plate promptly and cuts off the electricity supply under the pressure of bimetal leaf.Realized the temperature control purpose.The temperature control switch housing is a porcelain, and what bimetal leaf was used is the highly sensitive type bimetal leaf of 5J11 type that Tianjin electrical alloy factory produces, and it has high heat sensitivity and resistivity, can improve the sensitivity of temperature control switch.

On pot lid, also be provided with a vapour whistle (19).

Supply socket on the pot lid and existing socket are basic identical.Only shell and base have been done change, changed rectangle into garden shape, carried button to be fit to the double as pot lid.

The utility model is owing to be retrofitted in electric heater unit below the pot lid, overcome at the bottom of the kettle seepage and finishing, convenient disassembly, also realized the many usefulness of a kettle, and not only available electrical heating also can be used the heating of stove fire or gas kitchen ranges.
