Description

Kettle

The utility model relates to a kind of liquid heating apparatus, especially kettle, the liquid heating apparatus includes shape At the main body of the container of storage water, electric heating bottom and boiling detection device.

Such as according to kettle a kind of known to patent EP0786221, the kettle includes main body and steam lead, described Main body is disposed in above electric heating bottom, and the steam that the steam lead is used to give out when will boil is detected towards steam and passed Sensor transport, the steam lead includes entrance, and the entrance is disposed in the inward flange of the main body, the main body most The top of flood filling position.

In this kettle, when heated, the upper up-flow of water and steam can be generated, with close to boiling, the water and The upper up-flow of steam will generate increasing reflux in the Free Surface of water and splash.In order to avoid the water that splashes pass through it is described Entrance enters the steam lead and damages steam detection sensor, by retaining big air body above the Free Surface of water Long-pending maximum filling position limits the volume available of kettle.The volume of air can be occupied up to kettle total volume 40%.Therefore, the entrance of the steam lead and the distance abundance between the water surface at maximum filling position, to splash not The steam lead can be entered.

Therefore, for given available heating volume, the total volume of kettle is big and user is in order to look for local use Or storage kettle can meet difficulty.In addition, the packaging volume of kettle is big and kettle is transported from production plant to using The cost of person is enhanced.

One purpose of the utility model is to overcome disadvantages mentioned above and provide a kind of compact kettle, and the compact is burnt Kettle has the ratio of the optimization of volume available and total volume.

Another purpose of the utility model is to provide a kind of kettle designed simply and implement economy.

These purposes realize that the kettle includes main body and steam lead, the main body quilt by a kind of kettle It is arranged in the top of electric heating bottom, the steam that the steam lead is used to give out when will boil is towards steam detection sensor It transports, the steam lead includes entrance, and the entrance is disposed in the inward flange of the main body, in the most flood of the main body The top of filling position, which is characterized in that the kettle includes the protection for preventing water from entering the steam lead in boiling Device, the protective device include vertical blade, the vertical blade the entrance lower section, be disposed with the entrance certainly To the internal stretch of the main body, the blade corresponding to the inner circumference of main body in the upper up-flow of water and steam, mainly It is described maximum filling position horizontal plane lower section extend so that at least partly by when boiling the water and steam it is upper Up-flow shunts, and the protective device includes that the local derviation component of the entrance is left for the upper up-flow of shunting described in local derviation.

The vertical blade is disposed in the periphery of the opening and radial to the inward flange in the water and steam Upper up-flow in extend, to shunt it.The upper up-flow being so split will by more easily by the local derviation component guide from Open the entrance.

The entrance that this arrangement allows the vortex for reducing water surface in boiling and is limited in the steam lead The amplitude splashed.Therefore, the entrance of steam lead and distance between the water surface at maximum filling position can be smaller, and There is no water to enter the risk of steam lead, to allow to obtain the volume of air of the limitation above the Free Surface of water.Therefore, Kettle can be more compact, especially in height.

Maximum filling position is interpreted as in the main body of the kettle being that the safe volume of ratio that user marks out is more 15% maximum stage out.It is additionally considered that when the maximum filling position is boiling by the vertex of the vortex of the water surface, turbulent flow Position defined by the plane of process.

Advantageously, the blade has vertical gradient, and the vertical gradient permission establishes one between two vertical blades A region, section of the region in horizontal profile plane are gradually reduced along the propulsion of the ascent direction.

Therefore, the upper up-flow of the shunting is decelerated and the inner orientation to the main body when promoting to water surface.

Advantageously, the blade has horizontal gradient, and the horizontal gradient permission establishes one between two vertical blades A region, section of the region in the sectional elevation plane perpendicular to the blade is from the inner circumference along radial side To propulsion be gradually increased.

The arrangement allows when the rising of the shunting flows to the water surface and promotes, so that the rising of the shunting The internal flow towards the main body is flowed, the inward flange is left.

Preferably, the blade is parallel.

The arrangement allows to guide the upper up-flow of the shunting, mainly the direction opposite in the inward flange for being disposed with the entrance On.

Advantageously, the blade radial extends in the entrance.

Therefore, the upper up-flow shunted by blade will be distributed towards the front of the entrance and two sides.

Preferably, effective packed height of the kettle is between the bottom and the maximum filling position, and Vertically the height between the 10% to 50% of the effective height extends the blade, and preferably 30%.

Advantageously, the blade includes two opposed surfaces and at least one described surface includes local derviation component.

Therefore, described to be drawn along the surface for carrying the local derviation component towards the upper up-flow that the Free Surface promotes The entrance is opened in diversion.

Preferably, the local derviation component is by least one towards the linear protrusion shape extended inside and above the main body At.

Therefore, the upper up-flow promoted along the surface towards Free Surface will be encountered towards the inside of the main body and upper The linear protrusion of Fang Yanshen and the inside that will be directed toward the main body, leave the entrance.

Advantageously, the blade is disposed in the lower section of wall, is especially equipped with the lower section of the porous wall through perforation, institute It is approximate horizontal and form the local derviation component to state wall.

The wall stops the upper up-flow of the water and steam that are shunted by the blade, and therefore, at it towards the freedom It is left into the entrance to the inside local derviation of the main body during the propulsion of surface.In addition, vapor bubbles will be trapped in The lower section of the wall, between the vertical blade, the wall is used to form the local derviation surface of the upper up-flow.The water and steaming Vapour by the perforation generation eddy currents, the eddy currents dissipate the upper up-flow energy a part.

Advantageously, the main body has the circular cross section of radius R, and the vertical blade is inscribed within by two radiuses In the angle sector that R and circular arc are formed, the entrance is disposed in the immediate vicinity of the circular arc.

Therefore, the entrance is by balance and the symmetrical turbulent flow for reducing water surface and the region of amplitude that limitation splashes is wrapped It encloses.

Preferably, the kettle includes dumping mouth, and the dumping mouth is arranged on the contrary completely with the entrance, and is worked as The protective device is by the upper up-flow of water and steam towards the dumping mouth local derviation when boiling.

Advantageously, the main body includes towards the dumping mouth through opening, and the opening that runs through is disposed in The lower section of the water surface of maximum filling position.

Therefore, in maximum filling position, being present in the water in opening prevents the water splashed from spraying by mouth.

By studying the embodiment shown by way of non-limiting examples referring to attached drawing, it is practical new that this will be best understood Type, in the accompanying drawings:
