Vacuum heat-preservation temperature-adjustable electric kettle

Technical Field

The embodiment of the utility model relates to an insulating pot technical field, concretely relates to vacuum heat preservation adjustable temperature electric kettle.

Background

The vacuum heat-preservation temperature-adjustable electric kettle is an electric kettle which is provided with a vacuum interlayer in the inner wall of a kettle body to efficiently heat water, and has the advantages of good heat-preservation effect, quick heating and the like.

The conventional vacuum heat-preservation temperature-adjustable electric kettle is heated by adopting a heating pipe, after the heating pipe is heated to a specified temperature, the heating pipe stops heating, and heat preservation is realized by sealing the electric kettle.

The vacuum electric kettle comprises a vacuum kettle body, a vacuum kettle bottom and a heating plate arranged above the vacuum kettle bottom, wherein the vacuum kettle body comprises an inner wall and an outer wall, a connecting wall extending downwards is arranged on the heating plate, an installation edge is arranged on the periphery of the vacuum kettle bottom, and the connecting wall and the installation edge are sequentially stacked at the bottom of the inner wall and fixedly connected through bolts. The vacuum electric kettle adopts a heating pipe heating mode, the connecting wall and the mounting edge are sequentially stacked at the bottom of the inner wall and fixedly connected through the bolt to reduce the kettle opening of the vacuum kettle body, and the heat insulation performance of the vacuum electric kettle is improved. And then divide into two vacuum storehouses with vacuum insulating pot, the kettle body is one, and the kettle bottom is single, is difficult to like this sealed and the cost is high.

There is also a problem in that if the user does not use the water directly after the water is boiled, or runs out of the water at one time, the water is cooled slowly all the time, which causes the predetermined demand to be not met when the hot water is used subsequently.

SUMMERY OF THE UTILITY MODEL

Therefore, the embodiment of the utility model provides a vacuum heat preservation can adjust temperature electric kettle to solve among the prior art because the water in the kettle is because the water that can't keep warm and lead to is after reacing appointed temperature, its temperature can last slow decline problem.

In order to achieve the above object, the embodiment of the present invention provides the following technical solutions:

a vacuum heat-preservation temperature-adjustable electric kettle comprises a shell, an inner container arranged in the shell, a heating pipe and a control circuit board which are arranged below the inner container, and also comprises a temperature sensing probe and a PTC heating body which are arranged below the inner container, wherein the control circuit board is electrically connected with the temperature sensing probe, the PTC heating body and the heating pipe, and a heat-preservation temperature adjusting button is arranged on the outer side of the shell; after the water in the inner container is heated to boiling by the heating pipe, the heat preservation is carried out, the heat preservation temperature is set by pressing the heat preservation temperature adjusting button, and when the water temperature in the inner container is reduced, the PTC heating body carries out low-power heating and temperature adjustment to the set temperature.

Furthermore, a vacuum layer is arranged between the shell and the inner container, and the heating pipe, the temperature sensing probe and the PTC heating body are all arranged at the bottom of the vacuum layer.

Furthermore, the bottom of the shell is fixedly arranged on a vacuumizing pipe communicated with the vacuum layer, the bottom of the shell is detachably connected with a bottom cover, and the vacuumizing pipe extends into the bottom cover from the bottom of the shell.

Furthermore, the bottom of the bottom cover is provided with a connector, the control circuit board is arranged in the bottom cover, the wiring of the control circuit board is connected with the connector, and the wiring of the heating pipe, the temperature sensing probe and the PTC heating body penetrates out of the vacuum-pumping pipe and is connected with the control circuit board.

Further, the bottom end of the vacuumizing tube is connected with a sealing ring, and the sealing ring is fixed with the heating tube, the temperature sensing probe and the PTC heating body through glue melting.

Furthermore, a temperature display electrically connected with the heat preservation temperature adjusting button is arranged on the outer wall of the shell.

Further, the shell is including locating the casing in the inner bag outside and connecting in the top cap at casing top, set firmly the sealing washer that closely laminates with the inner wall of casing on the outer wall of top cap.

The embodiment of the utility model provides a have following advantage:

inside need of traditional insulating pot open a steam hole in the kettle top, when steam temperature reachd the action of temperature shell fragment, insulating pot auto-power-off, but some consumers add water occasionally and too much probably overflow to temperature shell fragment there from the steam hole, first useful electric potential safety hazard, second temperature shell fragment can consequently the oxidation rust to lead to insensitive even auto-power-off inefficacy.

When this scheme is heating up water, the heating pipe heating and with water heating to the boiling, temperature-sensing probe senses the temperature and reaches the boiling and control heating pipe stop work. Then after the heat preservation temperature adjusting button is pressed to set the heat preservation temperature, the temperature sensing probe senses the temperature inside the liner in real time, and after the temperature inside the liner is sensed to be reduced to be lower than the set temperature, the PTC heating body performs low-power heating temperature adjustment; after the temperature sensing probe senses that the water in the inner container reaches the set temperature, the PTC heating body is controlled to stop working; and then the temperature of the water in the inner container is reduced again, and the temperature sensing probe controls the PTC heating body again to heat and regulate the temperature. Therefore, as long as the heat preservation temperature is set, the water temperature is in the set temperature state and cannot be changed no matter when the water in the kettle is taken.

Like this through temperature-sensing probe gather the temperature, first, can accurate auto-power-off, the second can the precision know the kettle in the temperature, the third internal system can effectively accurately adjust the temperature.

In addition, because the temperature sensing probe is adopted in the shell to sense the water temperature instead of a common mechanical temperature control elastic sheet, compared with the sensing mode of the temperature sensing probe, the structure is simpler; the current mechanical temperature shell fragment must be connected with connector an organic whole, and the bottom on vacuum layer is difficult to reach the vacuum, and this scheme temperature-sensing probe passes through the electric wire and links to each other with the connector, and the bottom of shell is sealed the bottom on vacuum layer through the bottom, and the vacuum also can be realized to the bottom on vacuum layer, gains bigger vacuum area like this, and the heat preservation effect of kettle is better.
