For the spilling restriction system of container

For electric liquid heaters tool, if utensil surprisingly tilts or goes over, then have the danger that hot liquid overflows.. because liquid is in or close boiling, so this spilling can make user or onlooker's rats after severe scald burn.

The spilling also existed by reducing or eliminating hot water saves the demand of energy, not waste hot water.

Propose in the prior art much in order to reduce or to limit the suggestion of this spilling.These schemes have the one in following three types substantially, and each type depends on user and activates and/or movable part.

I) manual type, such as, wherein, only when valve is manually released, just can pouring liquid: such as, Figure 13 a to 13f of WO-A-2011/101642, wherein said valve is combined with user operation formula actuator.

Ii) automatic type, in the scheme of automatic type, only when utensil is in particular orientation, adopts one or more parts of the orientation movement along with utensil, and such as, gravity, could pouring liquid.Such as, Figure 15 a to 21b of WO-A-2011/101642 illustrates the gravity deflection pressure type valve of pendulum form, and it to be pivotably mounted on vertical axis and by pendulum supports support.Pendulum is subject to the effect of corresponding spring from contrary side, with at utensil centering pendulum uprightly or when toppling over towards Hu Zui forward.The active force of spring is enough to any friction overcome between pendulum and pendulum strutting piece, makes pendulum be in balance.When utensil is toppled over for toppling over towards Hu Zui, the central recess in pendulum allows liquid enter lid chamber through hole and enter Hu Zui through hole subsequently.

Iii) inertial type, wherein said valve is sensitive to impact and/or quick deceleration.Such as, Figure 14 a to 14d of WO-A-2011/101642 illustrates valve seat, and it has the inside protuberance that the spout side towards lid lower wall is located, and this prevents conical valve upward sliding and closes described hole when utensil dumps forward for toppling over.But if utensil dumps forward suddenly, then described valve will be skipped protuberance and be sealed on lid on sealing surface.If utensil side direction or topple over backward, then valve member will not engaged by protuberance, but will be sealed on lid on sealing surface, thus closes described hole.

Frequently, this simple and easy use making the setting of utensil safety also may limit utensil.

Prior art great majority relate to domestic water boiling apparatus, hereinafter referred to as Safety kettle.

A particular problem in kettle be normal using (fill and topple over and the heating and cooling cycle process in) and abnormality under (such as, utensil overturning) all need to provide pressure relief device and/or discharger on utensil.Substantially the Hu Zui of kettle is used as main earth pressure release and the discharger of steam, and expands in order to hold and shrink.. when Hu Zui is sealed or part seals such as preventing from overflowing, independent main discharger is set usually.

Another discharge for Safety kettle requires it is the isostasy needed between reservoir and air, and such as water freely can be toppled over from reservoir.

For the kettle combining the temperature controller (such as steam switching device shifter) installed away from described reservoir, steam pipe can be communicated with between reservoir and steam switching device shifter, and this steam pipe can provide auxiliary discharger and/or pressure equalization means for described utensil.

In Safety kettle, main discharge or secondary discharger can limit by overflowing limiting part, and alternatively or additionally, excessive water pressure can cause main or secondary discharger to spray the water of heating.

When wireless kettle, after kettle goes over, the temperature difference between heating element and water can cause boiling continuously in the short time, even if after making power-off, pressure also can continue to increase to some degree.

Such as, JP-A-2008212315 discloses a kind of independent manual type Safety kettle of discharging outlet had for steam.To Safety kettle commercially available on Japanese market with based in test disclosed in this patent application, after kettle tilts, boiling water is ejected into kettle sidepiece strong from discharge outlet.

In addition, steam pressure can make hot water enter into handle and/or subbase portion by steam pipe, thus surprisingly contacts the surface of heating and/or the risk of liquid when user attempts there is user when propping up utensil after utensil tilts.Further, also there is the risk that too much water contact is contained in the electric elements in handle and/or subbase portion.

But as shown in the example of GB-A-2272629, if heating container passes through interlock or valve is completely airtight, then having steam pressure can increase until the danger of container explosion at described internal tank.

Another problem to be solved in the equipment such as Safety kettle needs to allow to be easy to fill and/or topple over.

The open WO-A-2011/101642 of patent of the applicant discloses multiple device in order to overcome above problem, the plurality of device comprises the commercially available system based on mobile swing device, its allow user when not needing user to activate from Safety kettle pouring allowing provide and overflow the main and/or auxiliary discharge device of restriction.

The domestic water heating appliances that headroom reduces

In the domestic water heating appliances of such as kettle, preferably during heating process, water can not from Hu Zui by splash or injection.Usually, when the motion of water can be referred to as turbulent flow, the water probably injected or splash from kettle mouth after reaching boiling.Usually, the time of water boiling is longer, and this turbulent flow is fiercer, and more likely makes water spray or splash from Hu Zui.Usually, more high-power heating element result in fiercer turbulent flow.

Be known as Hu Zui and add baffle plate or other device to help the injected or splash during heating process of minimizing water.But baffle plate or other device can need movable part, and which increase the complexity of assembling.Usually, movable part can need the manpower intervention of some forms, and therefore utensil can be filled by such as Hu Zui disclosed in GB-A-952689 or be turned.

The known baffle plate that provides in the region of Hu Zui is to prevent water injected or splash during heating process.Usually, these baffle plates are provided to be used as Hu Zui barrier below.But the problem of this layout is, baffle plate may only turbulent water shift to and/or impingement baffles face time just provide barrier.In some kettles, turbulent water may be seethed with excitement sharp and move in all directions, that is, omnirange moves.In this case, baffle plate is not fully effective when anti-sealing sprays or overflows during heating process, because turbulent water via the gap bypass between baffle plate and water kettle body or may walk around baffle plate.

For illustrating and knowing object, from accompanying drawing, eliminate inessential parts.

Figure 58 diagram is as prior art utensil 1a disclosed in the open WO-A1-2012/085602 of the patent of applicant, and wherein damper for forming 730 is arranged in the holder 5 of utensil 1a, turns to away from kettle mouth 7 and turn to the rear portion of utensil 1a to make turbulent water.In this prior art is arranged, gap can be arranged between the upper end of baffle plate 730a and lid 8, overflows from holder 5 for being made excess steam when water heats.

The prior art of Figure 58 arranges that the combination that also may depend on damper for forming 730 and heat distribution device 741,742 is to contribute to the management of the water turbulence in liquid heater 1a.

It is also known that and to provide above water level ' headroom ', make between water level and kettle mouth, provide space to hold the turbulent flow of boiling water, and therefore help water injected or splash during heating process.The larger headroom that needs of kettle heating power is larger, to hold fiercer turbulent flow.Usually, the headroom be arranged in 3kw, the kettle of 1.7 liters can occupy up to holder 30% volume, which increase the manufactured materials cost of utensil and transport and shipment and delivery cost.

Such as, in the kettle that typical 3kw/1.7 rises, utilize parallel side portions, headroom has the height of about 47 millimeters, and in the conical kettle of similar 3kw/1.7 liter, headroom has the height of about 64 millimeters.

The device disclosed in order to reduce headroom required in liquid heater is below described.In a particular embodiment, in conical kettle, headroom can reduce about 11.5 millimeters, and headroom can reduce about 8.5 millimeters in parallel side portions kettle, and does not need the operation of user or automatic kettle mouth baffle plate.

Minimizing on this height can reduce size and the volume of quantity of material and the encapsulation used.According to typical package dimension, the reduction that can estimate the height of the utensil between 8.5 and 11.5 millimeters can reduce the encapsulation volume of 3 to 4% further.

In addition, the reduction on utensil height is also by corresponding for the reduction of the volume with headroom.Therefore, this can also reduce the time that the steam for producing by filling headroom 222 with boiling water spends, and the sensitive control switch of steam can be caused to cut off the rapid response and/or the startup that are just being supplied to the power of heating plate 12.Therefore, this can reduce the energy ezpenditure of utensil 1.

Rupturing duty supply early can also reduce ' boil afterwards ' (after boil, after power disconnects, the waste heat of element makes water be continued to boil), and therefore further reduce water by possibility that is injected from kettle mouth or splash.

In addition, present embodiments provide a kind of layout, wherein the operation of baffle plate and/or function are by the impact of the heat distribution of heating element plate.
