Description
Technical Field
The invention relates to the technical field of domestic electric appliances, in particular to an electric kettle capable of indicating that water is boiled.
Background
At present, most of electric heating kettles on the market are automatically disconnected after water is boiled, if a user does not timely treat the boiled water after the water is boiled, the user may forget whether the water in the kettle is boiled or not after the boiled water is changed to the normal temperature for a period of time, or other users can not judge whether the water in the kettle is boiled or not, so that the cold boiled water can be heated again possibly. This causes inconvenience to users who want to drink cool boiled water and wastes energy.
In order to solve the problem, some water boiling memory indicating devices are available on the market, such as chinese patent application No. 201510347328.5, the technical solution named "water boiling memory indicating device and water kettle with it", which comprises a body, a status indicating needle, a driving member, and a temperature sensor, wherein the temperature sensor comprises a first temperature sensing structure, when the temperature of the water boiling memory indicating device is increased, the first temperature sensing structure drives the driving member to move along the first direction, and the driving member drives the status indicating needle to move from an initial position to a status indicating position; when the temperature starts to decrease from the increased temperature, the first temperature sensing structure drives the driving part to movably reset along the direction opposite to the first direction, and the state indicating pointer continuously stays at the state indicating position. When the water is boiled and cooled, although the user knows that the water is boiled, the state indicating pointer returns to the original unheated indicating state under the action of the gravity of the user as long as the user pours the water once, so that the indication that the water is boiled is eliminated, and the problem of weak persistence exists. Therefore, the water boiling memory indicating device is only suitable for the electric heating kettle which is poured into the container once after some water is boiled, and the application range is small.
Disclosure of Invention
The invention aims to provide an electric kettle capable of indicating that water is boiled, which has the advantages of simple structure, reasonable design, wide application range, water indicating safety and the like.
The technical scheme of the invention is realized as follows: an electric kettle capable of indicating that water is boiled comprises 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 stopping position is formed at the bottom of the slope; the section of the path from the initial concave position to the ball stopping position is called a ball slideway, and 1 ball works in the ball slideway; the initial concave position is close to the rotating shaft, and the ball retaining position is close to the kettle opening; the kettle cover is characterized by further comprising a temperature-sensitive telescopic piece, 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 deformed when being heated under the covered state of the kettle cover and pushing the ball in the initial concave position away from the initial concave position and rolling to a ball stopping 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 filled into the kettle body, the kettle cover is in an open state, and the ball bearings move to the initial concave position automatically under the action of gravity. After the water injection is finished, the kettle cover is covered, and the ball is still 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 simultaneously and well transferred to the temperature-sensitive telescopic piece, 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 piece also reaches the degree of pushing the balls in the initial concave position out, and after the balls are pushed out of the initial concave position, the balls roll through the slope and finally stay at the ball stay position. The ball is positioned at the ball stop position, which 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. Because the ball stop position is at the position close to the kettle opening, even if the water in the kettle is partially or completely poured out, the ball stop position is the lowest position of the ball slideway under the two conditions of pouring the water and putting the electric kettle again after the water pouring is finished, and the ball can not leave the ball stop position all the time under the conditions. Once the kettle cover is opened, the posture of the ball slideway on the space is changed, at the moment, the ball stopping position is changed into the highest position of the ball slideway, the initial concave position is changed into the lowest position of the ball slideway, and the ball can move to the initial concave position direction by self under the action of gravity. As for the fact that the ball cannot enter the initial concave position and stop, the current cold and hot states of the temperature-sensitive expansion piece are seen: when the temperature of the temperature-sensitive telescopic part is still hot enough, the ball is blocked by the temperature-sensitive telescopic part and cannot enter the initial concave position; when the temperature of the temperature sensitive telescoping member is low enough to return or partially return to its pre-heated shape, the temperature sensitive telescoping member will partially or completely exit the home recess without blocking the ball from falling into the home recess. Since one is only confused as to whether the water in the kettle is boiled, this means that even if the water in the kettle is once boiled, it has been left to cool for a sufficient time, at which time the temperature expansion element has apparently cooled down and regained its pre-heated shape without blocking the balls from falling into the initial 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 be quickly cooled to restore the original shape. So that the embarrassment that the ball can not return to the initial concave position generally does not occur. Through the working process, the water in the kettle is not boiled when the ball is in 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 is opened), so that the water in the kettle is not suitable for drinking; the ball stays at the ball stopping position, which indicates that the water is boiled and the kettle cover is not opened, and indicates that the water in the kettle is safe at the moment. The user can easily judge whether the water in the kettle can be drunk or not through the position where the ball stays.
Furthermore, 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 separating from the ball slide way and not influencing the positions where the balls are observed.
Furthermore, the observation window is made of transparent materials, and waterproof and dustproof sealing is formed on the ball slideway.
Further, the inner cover is a metal plate having a heat conductive property.
Further, the temperature-sensitive expansion piece can be a piece made of bimetallic strips and provided with a C-shaped part.
Furthermore, the end of the temperature-sensitive telescopic piece used for pushing the ball is provided with a pushing part, a pushing inclined plane is formed on the pushing part, and the pushing inclined plane is arranged towards 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.
