Description

A thermal insulation electric kettle

technical field

The utility model relates to an electric kettle.

Background technique

Electric kettles are one of the commonly used small household appliances. Generally speaking, electric kettles are mainly used for heating liquids, and they lack functions such as heat preservation. At present, one way to increase the heat preservation time of electric kettles is to use power heat preservation, that is, electric kettles After the internal hot water is boiled, repeated heating is used to realize the heat preservation function. This method consumes a lot of electric energy and wastes a lot of resources, and repeated heating will cause water quality safety problems. Another method is to extend the heat preservation time and improve the heat preservation effect by adding a heat insulation layer or radiation layer or heat preservation material to the main body of the electric kettle to reduce heat convection transfer and delay heat transfer. The disadvantages of the structure are: many spare parts, complex structure, many assembly processes, low production efficiency, high manufacturing cost, poor heat preservation effect, and short heat preservation time.

In addition, the mouth of the general electric kettle is designed to connect the inner cavity of the kettle with the outside, which will cause the liquid in the kettle to easily dissipate heat through the lid or spout, resulting in poor insulation effect of the electric kettle and shaking of the electric kettle Or after it is accidentally knocked down, the hot water will flow out and cause the risk of scalding the user.

Contents of the invention

The technical problem to be solved by the utility model is to provide a thermal insulation electric kettle, which has good thermal insulation performance and can prevent the liquid from flowing out when the kettle body is tilted or shaken.

The technical solution adopted by the utility model to solve the technical problem is: an insulated electric kettle, including an insulated kettle cover assembly, a spout assembly, an insulated kettle body assembly including the outer wall and the inner cavity of the kettle, a kettle bottom assembly and a base assembly, The spout assembly is fixedly connected to the insulated pot body assembly, the insulated pot lid assembly is detachably connected to the spout assembly, and a sealing member is arranged between the two; the insulated pot lid assembly is formed with steam and water that communicate with the inner cavity of the pot. The integrated outlet passage of the integrated outlet passage is provided with a steam sealing part that can be selectively opened under a certain pressure at the steam outlet of the integrated outlet passage; A double-layer heat insulation structure, the double-layer heat insulation structure includes a first heat insulation board and a second heat insulation board, a first bottom heat insulation closed cavity is formed between the bottom of the outer side wall and the first heat insulation board, A second heat-insulating closed cavity at the bottom is formed between the first heat insulation board and the second heat insulation board.

The integrated channel of steam and hot water optimizes the structure of the pot lid assembly, reduces the parts of the pot lid assembly, facilitates assembly, and prevents users from being accidentally burned by steam.

Further, the steam sealing part is a steam valve made of silica gel or silicon rubber. When the steam pressure in the inner cavity of the kettle reaches or exceeds a certain preset value, the steam valve will be deformed under pressure. Thereby, the steam outlet provided on the lower cover part is opened. When the liquid in the pot is heated to boiling, the steam pressure makes a gap between the steam valve and the heat preservation pot cover assembly, and the steam in the pot can pass through the gap between the steam valve and the heat preservation pot cover assembly to realize the integration of steam and water. The outlet channel discharges the inner cavity of the jug. When the heating of the liquid in the pot is stopped, the steam valve part returns to the original state, which ensures the sealing effect of the inner cavity of the pot. When it is necessary to use the liquid in the pot, press the button on the handle assembly to make the lower cover part move downward relative to the combination part composed of the middle cover part and the upper cover part, and when the lower cover part is combined with the A water outlet connecting the integrated outlet channel and the inner cavity of the pot is formed between the parts, and the liquid in the pot flows out of the spout through the water outlet.

Further, the bottom assembly of the pot includes the first heat insulation board, the second heat insulation board, the heat insulating plastic of the bottom shell, the bottom shell and the bottom cover, and the first heat insulation board is provided with an electronic signal transmission line hole.

Further, a heating system and a temperature control system with a trip protection function are arranged in the first bottom heat-insulating closed cavity, an electric coupler is set in the second bottom heat-insulated closed cavity, and the wiring of the heating system and the temperature control system Connect with the pot bottom assembly through the electronic signal transmission line hole. When the vacuum insulated electric kettle is turned on, when the water in the pot body cavity reaches boiling, the temperature control system will trip the protection. At this time, no matter whether the pot body is removed from the power supply box, the water in the pot body component cavity will stop. Heating, timely power-off protection saves energy consumption, and the double-layer bottom thermal insulation energy storage structure further improves the thermal insulation effect and prolongs the thermal insulation time.

Further, the second bottom heat-insulating closed cavity can be evacuated or filled with heat-insulating material, so as to enhance the thermal insulation effect as required.
