Description
Technical Field
The invention relates to the technical field of household appliances, in particular to an electric kettle capable of indicating that water is boiled.
Background
At present, most electric kettles on the market are automatically disconnected after water is boiled, if a user does not timely treat the electric kettles after water is boiled, after a period of time, the water in the electric kettles is possibly forgotten to be boiled or other users cannot judge whether the water in the electric kettles is boiled, so that the electric kettles possibly reheat cool boiled water. This causes inconvenience to users who originally want to drink cool boiled water and also wastes energy.
In order to solve the problem, some water-boiling memory indication devices are presented in the market, and the indication devices comprise a body, a state indication needle, a driving piece and a temperature sensor, wherein the temperature sensor comprises a first temperature sensing structure, when the temperature of the water-boiling memory indication device is increased, the first temperature sensing structure drives the driving piece to move along the first direction, and the driving piece drives the state indication needle to move from an initial position to a state indication position, as in the technical scheme of China patent application No. 201510347328.5, namely the water-boiling memory indication device and a kettle with the water-boiling memory indication device; when the temperature starts to decrease from the increased temperature, the first temperature sensing structure drives the driving piece to movably reset along the direction opposite to the first direction, and the state indication pointer keeps at the state indication position. When the water boiling memory indicating device is applied, the water boiling memory indicating device is arranged on a kettle, and after the water is boiled and cooled, a user knows that the water is boiled at the moment, but only if the user pours the water once, the state indicating pointer returns to the original unheated indicating state under the action of self gravity, so that the problem of weak persistence caused by the indication that the water is boiled is solved. Therefore, the water boiling memory indicating device is only suitable for being applied to an electric kettle which is poured into a container once after some water is boiled, and has a small application range.
Disclosure of Invention
The invention aims to provide an electric kettle capable of indicating water once boiled, which has the advantages of simple structure, reasonable design, wide application range, water safety indication and the like.
The technical scheme of the invention is realized as follows: an electric kettle capable of indicating that water is boiled, comprising a kettle body and a kettle cover; the kettle body is provided with a kettle opening, the kettle body and the kettle cover are connected together through a rotating shaft, and the position of the rotating shaft is far away from the position of the kettle opening; the kettle cover comprises an outer cover and an inner cover; particularly, the outer cover is provided with a slope, an initial concave position is formed at the top of the slope, and a ball stop position is formed at the bottom of the slope; the path from the initial concave position to the ball stop position is called a ball slide way, and 1 ball works in the ball slide way; the initial concave position is close to the rotating shaft, and the ball stopping position is close to the kettle opening; the kettle cover is characterized by further comprising a temperature-sensitive telescopic piece, wherein one end of the temperature-sensitive telescopic piece is fixedly connected with the inner cover and conducts heat, and the other end of the temperature-sensitive telescopic piece is used for extending into the initial concave position when the temperature-sensitive telescopic piece is thermally deformed in a cover closing state of the kettle cover and pushing a ball at the initial concave position away from the initial concave position to roll to a ball stop position; when the kettle cover is opened, the ball automatically returns to the initial concave position under the action of gravity.
The working principle of the invention is as follows: when water needs to be injected into the kettle body, the kettle cover is necessarily in an opened state, and at the moment, the ball is necessarily automatically moved to an initial concave position under the action of gravity. After the water injection is completed, the kettle cover is covered, and the ball can still be positioned in the initial concave position. When the water in the kettle body is heated, the inner cover of the kettle cover which is usually made of metal materials is also heated quickly, and heat is well transferred to the temperature-sensitive telescopic piece at the same time, so that the temperature-sensitive telescopic piece is thermally deformed. When the water is heated to boiling, the thermal deformation of the temperature-sensitive telescopic member reaches the degree that the balls in the initial concave position are pushed away, and after the balls are pushed away from the initial concave position, the balls roll through the slope and finally stay on the ball stay position. The ball is in the ball stay position means that the water in the kettle is boiled, and the user can judge the boiling state of the water in the kettle according to the water boiling state. Because the ball stay position is at the position close to the kettle mouth, even if the water in the kettle is partially or completely poured out, the ball stay position is the lowest position of the ball slide way in the water pouring process and under the condition that the electric kettle is replaced after the water is poured, and therefore the ball cannot leave the ball stay position all the time under the conditions. Once the kettle cover is opened, the gesture of the ball slide way in space can be changed, at the moment, the ball stay position becomes the highest position of the ball slide way, the initial concave position becomes the lowest position of the ball slide way, and the ball can automatically move to the initial concave position under the action of gravity. As for the ball can not enter the initial concave position and stay, the current cold and hot state of the temperature sensing telescopic piece is considered: when the current temperature of the temperature-sensitive telescopic piece is still hot enough, the ball is blocked by the temperature-sensitive telescopic piece and cannot enter the initial concave position; when the temperature-sensitive expansion piece is low enough to recover or partially recover its pre-heated shape, the temperature-sensitive expansion piece will partially or completely exit the starting recess without blocking the balls from falling into the starting recess. Since one is only confused as to whether the water in the kettle is boiled or not, this means that even if the water in the kettle has been boiled, it has been left for a sufficient time to cool, at which time the temperature telescoping member has apparently cooled down to resume its pre-heated shape without blocking the balls from falling into the starting recess. In addition, if the kettle cover is opened, the inner cover and the temperature-sensitive telescopic piece can quickly dissipate heat, so that the temperature-sensitive telescopic piece can quickly cool and restore the original shape. Therefore, the embarrassment that the ball cannot return to the initial concave position is avoided. Through the working process, the water in the kettle is not boiled when the ball is at the initial concave position, or the water is boiled but the kettle cover is opened (the water is unsafe for people who do not know when the kettle cover He Yin is opened), which means that the water in the kettle is not suitable for drinking; the ball resting position indicates that the water is boiled and the lid is not opened, indicating that the water in the kettle is safe. The user can easily judge whether the water in the kettle is available for drinking through the position where the ball stays.
Further, the outer cover is provided with an observation window for covering the ball slide way, and the observation window is used for preventing the balls from being separated from the ball slide way and does not influence the position where the balls are observed.
Further, the observation window is made of transparent materials, and a waterproof and dustproof seal is formed on the ball slide way.
Further, the inner cover is a metal plate with heat conducting property.
Further, the temperature-sensitive telescopic member may be a member made of a bimetal having a C-shaped portion.
Further, the end of the temperature-sensing telescopic piece for pushing the ball is provided with a pushing part, and a pushing inclined plane is formed on the pushing part and faces the direction of the slope.
The invention has the beneficial effects that: has the advantages of simple structure, reasonable design, wide application range, water safety indication and the like.
