Technical field

The utility model relates to liquid heater tools, and more particularly to the water cooking appliance of such as kettle etc.

Background technique

It is well known that lime scale (" scale ") deposit in liquid heater tool can generate undesirable particle dirt Dye.In the household appliance of such as kettle, this is usually mitigated by nozzle filter, the nozzle filter retention (retain) any scale particles, so that they will not be poured out together with the liquid being heated, for example, into the cup of user. However, this is only partial solution, because scale particles are not collected, but simply fall back to what liquid was heated In chamber.This just needs user to carry out periodic cleaning utensil to remove incrustation.

There is still a need for improve liquid heating apparatus to handle scale.

Summary of the invention

According to the utility model, a kind of liquid heater tool is provided, comprising:

Liquid has the nozzle for pouring out liquid；

Particulate filter is arranged in the liquid, for leading to liquid before pouring out from the nozzle It crosses wherein；And

Particle trapper is arranged in below the particulate filter in liquid, is cut with capture by particulate filter The microparticle material stayed；

Wherein, the particle trapper include limited by the one or more walls extended downwardly from upper end it is partially enclosed Compartment and the lid that the compartment is partly closed in the extension of the upper end of compartment, wherein at least one wall of the compartment is to liquid Body is permeable.

It should be understood that this particle trapper is to the particulate filter being generally arranged at nozzle or near it It is additional, so that liquid passes through wherein before pouring out from nozzle.The partially enclosed compartment of particle trapper allows microparticle material The entrance of (such as scale), but tend to retain the material so that it is collected rather than is freely moved back into liquid In.It is impermeable since at least one wall is permeable for liquid, but for microparticle material, so liquid can It is discharged by compartment, and leaves microparticle material.The permeability of one or more walls is selected to ensure that the macroscopic view of at least scale Particle (lime scale, i.e. calcium carbonate) is trapped in compartment.

A preferred feature according to the present utility model, essentially all of one or more of walls can be to liquid It is permeable.For example, compartment can be formed by net walls.This may insure quickly to drain, but may not be necessary, because The only liquid of relatively smaller volume can be swept away by trap come.Preferred feature according to the present utility model, at least one wall It may include permeable window.For example, one or more of walls can be solid, being provided with can for drain purpose Permeate window or multiple permeable windows.

Particle trapper includes extending in compartment upper end with the lid of partly enclosed compartment.It should be understood that lid is not Completely enclosed compartment, allows liquid and scale to flow downwardly into compartment.Preferably, lid is impermeable to liquid, so that Liquid is obtained to tend to flow through lid and scale is carried in compartment.Lid can essentially horizontally extend through the upper end of compartment.But Be that this will lead to some ponding (pooling) on the top of lid and positioned at the scale covered, rather than be washed into compartment with Just it collects.Preferred feature according to the present utility model, lid angularly enter downwards compartment.Lid can be with respect to the horizontal plane with 0 Any angle between degree and 90 degree is at an angle of downwards.Angle in order to promote liquid to flow into compartment, preferably between 30 ° to 60 °.

Lid can be substantially flat, especially if if it is at an angle of downwards as described above.However, applicant is Through recognizing, compartment can be therefore missed and ensuring that liquid will not easily flow out the side of lid to optimize scale and collect.Root According to the preferred feature of the utility model, the lid includes at least one upright flange.For example, lid may include a pair of upright Side flange.In the embodiment that lid is at an angle of downwards, upright side flange may be arranged at the either side on surface angled downwards, Thus the side edge of liquid outflow lid is prevented.

The closed degree of end part may depend on how far lid extends across upper end to compartment on it.It is according to the present utility model Preferred feature, it is described cover compartment upper end extend across the cross-sectional area of the compartment at least 50%, 60%, 70%, 80% or 90%.This for keeping scale particles to become trapped in compartment and be advantageous, especially when utensil turn forward with When liquid is poured out from nozzle.If utensil tilts backwards during use, lid can also prevent scale particles from escaping from.

Particle trapper is designed to provide enough collected volumes, so that not needing during the working life of utensil It empties.However, wanting to empty microparticle material from compartment for user.Particle trapper therefore can be from liquid It removes, such as is removably mounting in chamber in heating chamber.Applicants have realized that for material to be caught Collect compartment lid and emptying compartment can be easy user between there is the requirement vied each other.Therefore, according to this The preferred feature of utility model, lid are moveable.For example, lid can be hingedly attached to trap.According to the utility model Preferred feature, lid can be removed from compartment or compartment can remove from the cover.It is therefore to be understood that trap is excellent Selection of land be include as separation member compartment and lid at least two-part construction.This means that user can it is mobile from compartment or Lid is removed more easily to obtain the content of (access) trap.

Particle trapper can be installed in liquid independently of particulate filter.Preferably, trap quilt It is mounted on the position for sufficiently closing to filter, so that being tended to fall into or be washed into trap by the material that filter stops. Preferred feature according to the present utility model, particle trapper are mounted so that the upper end of compartment is arranged to and particulate filter Lower end be overlapped.Ideally, trap is located at the underface of filter, so that microparticle material tends to become trapped in trapping In device, but the position of trap high cannot obtain, the liquid for pouring out compartment physical disturbance by filter.Trap can be by It is mounted so as to compartment and hangs down (hang down) in the lower end of filter.

Applicants have realized that facilitating dress using particulate filter as installation particle trapper with can be convenient It sets, so as to avoid in the needs of the mounting device additional elsewhere of liquid.Therefore, according to the present utility model Preferred feature, particle trapper are mounted to particulate filter.For example, particle trapper is connected to the lower end of particulate filter. Any suitable mounting arrangements can be used, such as are clasped or tongue and groove arrangement.Trap can fixedly or can Movably it is installed to filter.Moveable mounting arrangements may include the axis across trap and filter, for example, providing pivot Axis connection.

As discussed above, at least some embodiments, lid is convenient to separate with compartment, to want as user Make it possible to open trap when emptying trap.This can provide lid by filter and movably or removedly install It is realized to the compartment of filter.Filter is mounted on fixed position (although filter itself can also be with usually relative to nozzle It is removable in order to cleaning).In addition, applicant have appreciated that, when filter provides lid, has and retained by filter Microparticle material fall on the predefined paths for covering and then being punched into compartment.This can be to avoid trap with filter and lid Between be mounted there are the mode in unexpected gap.Preferably, particulate filter and lid are integrally formed into single part.

Preferred feature according to the present utility model, filter include extending in liquid to form trap The shelf (shelf) of lid.Shelf can extend from the lower end of filter.As described above, shelf can angularly enter downwards Compartment and/or including at least one upright flange.Such shelf arrangement may insure to be not present between filter and lid Gap, so that substantially all being fallen on shelf by all microparticle materials that filter retains.In such embodiments, compartment can Movably or to be removably attached to shelf.This means that for the ease of obtain, compartment can relative to lid be moved or It is removed.

Preferred feature according to the present utility model, particle trapper may be mounted at the fixed bit in liquid It sets.When utensil turns forward to pour out liquid by nozzle, it may be desirable to which trap is maintained at fixed position.In particular, Being not intended to trap to be moved to may interfere with the position that liquid flows to nozzle.During normal use, liquid heater tool tendency In sitting stationary on a horizontal surface or being lifted and turn forward (that is, nozzle is downward), to pour out liquid by nozzle. Applicant is existing it has been recognized that liquid heater tool can be lifted and tilt backwards (that is, nozzle is upward), to assist to collect trap Interior scale, this will not occur during normal use.Even if trap is mounted on fixed position, this way is potentially contributed to The scale being trapped falls from filter and enters in trap.However, can be by the way that trap be movably mounted at liquid The movement is assisted in heating chamber, so that trap is moved to collection position when utensil tilts backwards.Collecting position can be with It is for example to make the upper end of compartment closer to the position of filter.When utensil tilts backwards, the effect of gravity is by scale particles It is pulled out from filter, and the collection position of trap is to be arranged to preferably those particles for falling of capture (catch) Position.

Preferred feature according to the present utility model, other than above-mentioned any preferred feature, the trap is pivotable Ground is mounted in the liquid.In general, it is desirable to which trap pivots, so that it takes not relative to filter Same angle position, this depends on the inclined angle of utensil.When utensil turns forward, this can help trap to swing to not The position that interference liquid is poured out from nozzle.In addition, alternatively, this can help trap swing to collect position, with The scale that capture is fallen when utensil tilts backwards.The trap can be pivotally mounted, so as to relative to the filter Take a series of different angle positions.Under the tilt angle of given utensil, the angle position of trap is of course depend upon Its center of gravity, and this is adjustable when designing compartment.

Additionally or alternatively, compartment can be pivotably mounted relative to lid.For example, lid can be hinged.For example, according to Preferred feature, compartment can be pivotably connected to shelf.This means that the wall of compartment can be pivoted relative to lid to change How to partially turn off or open compartment.When utensil tilts backwards, and trap is moved to collection position, this is for making compartment more Add opening, for example, falling back in trap with any scale for forcing filter to retain without especially being had by the obstruction covered With.

As described above, the center of gravity of the center of gravity of trap, especially compartment will determine the angle position of trap.Work as trap When being pivotably mounted in liquid, it is contemplated that when utensil turns forward to topple over, trap will tend to It is pivoted (i.e. towards nozzle) forward.But this movement of trap may interfere with liquid and freely be poured out by nozzle.Work as device When tool turns forward from its static (i.e. vertical) position, it is preferred that trap, which is kept essentially stationary,.This can be by that will catch The center of gravity of storage is located so that trap is not inclined to pivot forward when utensil turns forward to topple over and (adds towards liquid The wall of hot chamber) and be ensured that.No matter utensil is vertical or turns forward, and trap can be all sagging in identical position. Additionally or alternatively, trap can be pivotably mounted, wherein compartment is against filter when utensil is in a vertical position And/or the wall of liquid.The wall of liquid can be straight or curved, for example, this depends on utensil Shape.Shape regardless of the wall for forming liquid, compartment can be against filter, such as provides the mistake of backstop The shelf of filter.Since compartment is against filter and/or the wall of liquid, even if when utensil turns forward, Trap can not pivot forward.

Although trap can be arranged to be kept essentially stationary when utensil turns forward, it is preferred that (such as It is upper described), when utensil is tilted backwards from static (i.e. vertical) position, trap, which is pivoted to, collects position, which makes Compartment upper end is closer to filter.Therefore, preferred feature according to the present utility model, additionally or alternatively, the trapping The center of gravity of device is positioned such that when the utensil is tilted backwards from vertical position, the trap tend to pivot backward (i.e. from Open the wall of the liquid).When trap pivots backward, make collecting the partially enclosed upper end of position compartment more Close to filter.Preferred feature according to the present utility model, center of gravity are positioned such that tilt backwards when utensil relative to level When face is 10 °, 20 °, 30 ° or 40 ° of angles, the upper end of compartment is physically contacted closer to filter or with filter.Usually It is not intended to tilt backwards utensil more than 45 °, be overflowed because this may cause liquid from liquid.

It collects position and has described as the position for making the upper end of compartment closer to filter or with filter physical contact It sets.This means that the trap is preferably positioned, to capture by mistake when the utensil is tilted backwards from its vertical rest position Filter stops and is forced any microparticle material fallen after rise downwards under the effect of gravity.However, the upper end of compartment is partly closed The fact may interfere with collection process.It is installed into compartment relative to covering in those of pivot embodiment, for example, lid is by mistake The shelf for the fixation that filter provides, then collecting position is preferably the position covered and pivoted downwards towards the wall of compartment.Example Such as, compartment can pivot backward, so as to contact collecting at least one wall of position with lid.This means that lid will not be in the upper of compartment End extends with partially enclosed compartment, or compartment is at least closed as to smaller degree.(work as utensil in the default location of trap When vertical), lid can extend across at least 50% cross-sectional area of compartment in the upper end of compartment.In the collection position of trap (when utensil tilts backwards), lid can extend across the cross-sectional area less than 50% of the upper end of compartment.So that compartment It is more open, and can preferably capture the scale fallen from filter.

It has already mentioned above, desirable for liquid can flow to nozzle to be poured out, without by depositing in liquid In the obstruction of particle trapper.The wall of trap, especially compartment can be shaped as aiding in this.According to the utility model Preferred feature, compartment includes the straight wall extended downwardly in the side near nozzle and downward in the side farthest from nozzle The curved wall of extension.Curved wall can permit liquid and flow more easily through compartment to reach nozzle.It is according to the present utility model excellent Select feature, compartment may include cross section substantially rectangular cross-sectional configuration in the vertical direction, which defines substantially and downwards The opposite straight wall extended downwardly of the curved wall of extension.When curved wall extends downwardly, it can be bent towards straight wall.Therefore every Between upper end rectangular cross section can be wider.

It is not special with the utility model other than the design of particulate filter provides the shelf of lid in addition to being optionally compartment It is related.Filter may be mounted in liquid, to intercept liquid before liquid is poured out nozzle.Alternatively, such as As most traditional, filter be may be mounted in nozzle.This is commonly known as " nozzle filter ".The particle mistake of any standard Filter constructions can be provided, it may for example comprise plastics or metal mesh.

Liquid can be formed by plastics as known in the art, metal and/or glass material.Technical staff The particular design that can have with unrestricted choice liquid heater.Liquid may include that immersion electrical heating elements or electricity add Hot radical seat, for example, (underfloor) heater under the so-called floor that can be found in many modern kettles.

Liquid heater tool can be any utensil for heating liquid, for example, teapot, coffee pot or other drinks Machine, milk bubble machine or any edible liquid heat utensil.However, the embodiments of the present invention can be used in particular for most possibly meeting with The water cooking appliance of scale problem.Therefore, liquid heater tool is preferably the calorifiers such as kettle.
