Description

A kind of improved thermal-insulation electric heating kettle

Technical field

The utility model is related to hot-water bottle field, especially a kind of improved thermal-insulation electric heating kettle.

Background technology

At present, existing hot-water bottle goes sensing in heating process by the coupler below the heat-generating pipe of kettle bottom The temperature at kettle bottom so as to judge whether the water of hot-water bottle reaches the temperature value specified, but because the double gold plaques in coupler can only be felt The temperature at kettle bottom is answered, therefore causes temperature-sensitive inaccurate, the low problem of induction sensitivity.

When part is using the pot lid component being fully sealed simultaneously, because the boiling water in hot-water bottle can produce high-temperature vapor, Space in hot-water bottle is set to produce larger pressure difference, when boiling water is taken, high-temperature vapor can spray moment in hot-water bottle, and it is right to be easy to People damages, to solve this problem, it will usually passage is reserved in pot lid component, can be drained during heating The vapor of high temperature, does not have steam ejection when boiling water is taken, so as to prevent the generation of personal injury accident, but, in heat When kettle body is toppled over, the water in hot-water bottle can spill from passage, and the hot water of high temperature is easily splashed to the hand of user Deng position, similarly easily to artificial into security incidents such as scalds.

Utility model content

The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, and provides a kind of simple and reasonable, A kind of improved thermal-insulation electric heating kettle of control temperature controller break-make hot-water bottle while draining high-temperature vapor in heating process.

The utility model solves the technical scheme that its technical problem used：

A kind of improved thermal-insulation electric heating kettle, including kettle body and the pot lid at the top of kettle body is covered, kettle body top is provided with kettle Mouth, the side wall of kettle body is provided with handle, and temperature controller is provided with handle, and the bottom of the pot lid is provided with annular seal space, annular seal space Bottom is provided with opening, be provided with opening can elastic folding closure, communication seals chamber and kettle are installed on the closure The first row air valve of intracoelomic cavity, is extended with first exhaust passage on annular seal space, the side of handle is extended with and first exhaust passage The exhaust connection of docking, the temperature controller in handle is connected by exhaust connection with first exhaust passage, on first row air valve First exhaust valve block is provided with, many valve first row air valve branch pieces are divided into by seam on first exhaust valve block.

When the thermal-insulation electric heating kettle of the structure makes in kettle steam pressure outer more than kettle atmospheric pressure, first row air valve branch piece is beaten Open, kettle can be made to be automatically drained out steam by first exhaust valve block, when kettle external and internal pressure reaches poised state, first exhaust Valve branch piece resets and closes, it is to avoid the heat in kettle body carries out heat exchange so as to accelerate the radiating speed of thermal-insulation electric heating kettle with air Degree, keeps kettle interior sealing, improves heat-insulating property, and when thermal-insulation electric heating kettle bottle body topples over hot water, first row air valve branch piece is closed, The gravity that hot water is subject in kettle body can not push first row air valve branch piece open, so as to solve kettle seepy question, and pressure release work With, it is to avoid steam impacts steam bimetal leaf for a long time, so that bimetal leaf service life is longer, safe and reliable, lifting is used Experience at family.

Dividing plate is extended with the annular seal space, annular seal space is divided into first row air cavity and second row air cavity, first by dividing plate Exhaust passage and first row air valve are arranged on first row air cavity, and connection second is provided with the closure of correspondence second row air cavity Discharge chamber and the second row air valve of kettle body intracavity, are extended with second exhaust passage, second exhaust passage and kettle on second row air cavity Mouth is connected.

Annular seal space is divided into first row air cavity and second row air cavity by dividing plate, makes first row air cavity and kettle body intracavity, handle A seal cavity for circulation is constituted, in heating process, the vapor of the rising of heating can be exhausted directly to the temperature control in handle Temperature sensor on device, it is to avoid in uphill process, the cold air outside thermal-insulation electric heating kettle is by spout and the water of temperature-sensitive for vapor Steam carries out heat exchange, reduces the temperature of vapor, and influence temperature controller senses the accuracy of water temperature, extension insulation by vapor The heat time of electric kettle, energy consumption is wasted, and lower the reliability of thermal-insulation electric heating kettle.

The seam is cross crotch, and cross crotch can guarantee that the sealing of thermal-insulation electric heating kettle, incline in thermal-insulation electric heating kettle bottle body The when of falling hot water, stops that hot water discharge outside kettle body from cross crotch, but can be opened in the vapor of high pressure and drain steam, it is ensured that guarantor The security of warm electric kettle.

The drive component for being driven with closure and being connect is installed in the pot lid, closure opposed open is beaten by drive component Open or close and close, simple structure is easy to operate, it is ensured that the sealing of thermal-insulation electric heating kettle, improve the heat insulating ability of thermal-insulation electric heating kettle Energy.

Seal groove is provided with the edge of the closure, sealing ring is installed in seal groove, sealing ring is sealed with opening Coordinate, it is to avoid gap discharge of the vapor of high pressure between closure and annular seal space, so as to reduce thermal-insulation electric heating kettle Hu Mi Sealing property.

The beneficial effects of the utility model are：

A kind of improved thermal-insulation electric heating kettle of the present utility model, simple structure is easy to operate, when thermal-insulation electric heating kettle makes When steam pressure is more than atmospheric pressure outside kettle in kettle, kettle can be made to be automatically drained out steam by first exhaust valve block, when in kettle When external pressure reaches poised state, it is to avoid the heat in kettle body carries out heat exchange so as to accelerate dissipating for thermal-insulation electric heating kettle with air Thermal velocity, keeps kettle interior sealing, improves heat-insulating property, and when thermal-insulation electric heating kettle bottle body topples over hot water, hot water is subject in kettle body Gravity can not push first row air valve branch piece open, it is safe and reliable so as to solve kettle seepy question, lift Consumer's Experience.
