Description

Technical Field

[0001] This utility model belongs to the field of electrical appliances, specifically relating to an electric kettle with automatic water filling. Background Technology

[0002] With the development of tea culture, tea sets have entered ordinary households and offices, and electric tea stoves are an indispensable heating appliance among tea sets.

[0003] Chinese utility model patent CN 208582216U discloses an electric kettle with good heat preservation effect, including a kettle body and an insulated outer shell. Both the kettle body and the insulated outer shell are hollow structures. The kettle body is located inside the insulated outer shell, and a base is installed at the bottom of the insulated outer shell. A spout is located on one side of the top of the kettle body. A water perforation hole is opened on the top side of the kettle body near the spout, and the spout communicates with the inner cavity of the kettle body through the water perforation hole. A lid is rotatably connected to the top side of the insulated outer shell away from the spout. A handle is also located on the top side of the insulated outer shell away from the spout. A gap is provided between the kettle body and the insulated outer shell, and two opposing heat preservation layers are arranged within the gap. Multiple sets of vertically arranged pressing mechanisms are provided between the heat preservation layers and the inner wall of the insulated outer shell, wherein the pressing mechanism includes a fixing block and a positioning block. However, the above-mentioned electric kettle has limited functionality and cannot meet consumers' needs for this type of product. Its main shortcomings are: 1. The automatic water supply is not ideal. After finishing each pot of water, you have to leave your seat to get more, which is very inconvenient and cannot meet the need to make tea with hot water at any time; 2. It connects directly to tap water and does not properly treat foreign objects (such as iron filings) in the water, which affects the health of users. Utility Model Content

[0038] An electric kettle with automatic water filling consists of the following components:

[0039] The base 3 is formed by the interlocking of the upper shell 35 and the base plate 39. The base 3 is connected to a water inlet pipe 31. The water inlet end of the water inlet pipe 31 is connected to a municipal water tap. A solenoid valve 37 is provided on the water inlet pipe 31 located inside the base 3. An electronic control board 36 is fixed on the base plate 39. A microcontroller is provided on the electronic control board 36.

[0040] The kettle body 2 includes an insulated inner pot 22. The bottom of the insulated inner pot 22 is provided with a water inlet hole. A pluggable self-sealing water connector is provided in the water inlet hole. A first water level detection sensor 23 is provided in the upper middle part of the inner side wall of the insulated inner pot 22. The output end of the first water level detection sensor 23 is connected to the end of the microcontroller. The output end of the microcontroller is connected to the input end of the solenoid valve 37 for controlling the opening and closing of the solenoid valve 37.

[0041] Furthermore, a filter element 38 is also provided on the base plate 39, and the water outlet end of the water inlet pipe 31 is connected to the water inlet end of the filter element 38 through a pipe.

[0042] Furthermore, the upper housing 35 of the base is provided with a side cover 33 near the filter element 38. The side cover 33 is designed to facilitate the replacement of the filter element 38.

[0043] Furthermore, a coupler 34 is provided in the middle of the upper shell 35 of the base. The water outlet of the filter element 38 is connected to the water inlet of the coupler 34 through a pipe. The water outlet of the coupler 34 is adapted to the pluggable self-sealing water connector embedded in the water inlet hole of the inner thermos flask 22.

[0044] Furthermore, the kettle body 2 also includes an outer shell 21 that is fastened to the outside of the insulated inner kettle 22. The outer shell 21 has a handle on its side, and the bottom of the insulated inner kettle 22 has a heating device. The output terminal of the microcontroller is connected to the input terminal of the heating device to control the start and stop of the heating device.

[0045] Furthermore, it also includes a lid 1, which is fastened to the outer shell 21.

[0046] Furthermore, the bottom of the lid 1 is also provided with a second water level sensor and a temperature sensor. The output terminals of the second water level sensor and the temperature sensor are connected to the microcontroller. The output terminal of the microcontroller is connected to the input terminal of the solenoid valve 37 to control the opening and closing of the solenoid valve 37.

[0047] Furthermore, a buzzer is provided on the top of the lid 1, and the output terminal of the microcontroller is connected to the input terminal of the buzzer.

[0048] Furthermore, the base 3 is also provided with a power cord 32 for connecting to external AC power.

[0049] In use, the water inlet pipe 31 continuously flows into the insulated inner pot 22 through the filter element 38 and coupler 34. When the water level in the insulated inner pot 22 reaches the detection position of the first water level sensor 23, the first water level sensor 23 sends a signal to the microcontroller. After receiving the corresponding signal, the microcontroller controls the solenoid valve 37 to close. The microcontroller then controls the heating device to heat the water in the insulated inner pot 22. After boiling, the temperature sensor at the bottom of the lid 1 detects that the water temperature in the insulated inner pot 22 has reached the threshold and sends a signal to the microcontroller. After receiving the corresponding signal, the microcontroller controls the heating device to stop working. The second water level sensor is a redundant design of the first water level sensor 23. When the first water level sensor 23 fails, and the second water level sensor is working, the microcontroller controls the buzzer to sound an alarm, informing the user that the first water level sensor 23 has failed.

[0050] The embodiments of this utility model have been described in detail above. However, this utility model is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of this utility model.
