Description

Electric liquid heating vessels

The present invention relates to electric liquid heating vessels, relate in particular to but not only relate to water heating vessels.

In western countries especially Britain, the boiling water that is used for making hot drink such as tea or coffee is at electric kettle or carry in the kettle and heating.Water seethes with excitement on demand, and the user holds the side that is placed in kettle or the handle at top, and water topples over out from container by Hu Zui.

Yet in the Orient, more generally use a kind of container bigger slightly than the kettle capacity in west, it in addition after the primary quantity of content capacity of heating is used, still keep connection so that can use remaining amount in a period of time afterwards.Usually be called " electric jar ".Institute's contents at first are heated to boiling, subsequently by a radiator valve insulation of second of control, small-power heating element heater usually.Liquid flows out from electric jar by machinery or electrically operated pump.Yet this structure is produced suitable costliness and complicated.

Therefore preferably can provide an electric liquid heating vessels, big relatively capacity be arranged, and can be raised easily, therefore get rid of the needs that are equipped with pump machanism.

Therefore, have according to electric liquid heating vessels provided by the invention: an opening is used to topple over; Electric heater unit is used for liquid in the heating container; And two spaced apartly toppled over handle, and it is arranged and makes in use described liquid heater to topple over handle and mention and therefrom pour out liquid with described.

Advantage of the present invention is that more substantial liquid can be heated, and the outflow of liquid do not need the pump installation of expensive complexity, but by on heating vessel, adorning two handles, so that it can with the hands be mentioned by the user and topple over easily.

According to a special preferred feature of the present invention, two handles are by longitudinally arranged apart, more preferably generally lay respectively at the top of heating vessel and base near.It has controllably, mentions the advantage with tilt container more easy and conveniently.

According to another preferred feature of the present invention, two handles are arranged in the side of container away from Hu Zui, are poured out from container when water thus, and the hand that can make the user is away from boiling hot water and steam.

According to another preferred feature of the present invention, following handle is made into a groove on the container kettle body.Most preferably, groove is that lower surface from container extends upward formation.Such layout makes the weight of the easier supporting container of user.The also favourable container that makes of groove seems more attractive in appearance.

According to special preferred feature of the present invention, a handle, preferred top is toppled over handle, topple over and non-dump position between be movably, preferably can pivot.In a preferred embodiment, up knob is pivotably mounted on the last rear portion of container, can pivot, and for example to the dump position (D score position) of basic horizontal, it extends back so that mention container from vertical non-dump position (" on " position).This handle can have makes motionless device on its two positions that selectively remain on it, anchor clamps for example, and it can unclamp by customer requirements.

Handle can be installed in all or part of the covering of removing of container, and this cover tape has the device that is fixed in the use location.

Moving of handle can have one or more additional functions.For example working as container is the connection situation, and handle can be used to mobile end cap to cover pouring opening, avoids the excessive effusion of steam in the heating process thus.End cap can slippage or pivot cover Hu Zui, but preferred end cap does not form airtight sealing, with the danger of avoiding potential container inner pressure to increase.Therefore container can have a blow vent or similar device, overflows in a kind of controllable mode to allow steam.On its dump position, the end cap withdrawal is poured out by opening to allow liquid.

In a preferred embodiment, handle also can be used for installation switching device, with the electric current supply of control to reservoir heater, this means when handle to move to its dump position place that heater will automatically not worked.For example the pivoting action of handle can pass to the separator levers arm of control device by suitable connection, type as describe, in general terms among the WO95/34187, it connects selectively or disconnects supply of electric power, or is connected to the cover contact under the control structure as shown in W097/04694.Therefore in this preferred embodiment, the user only needs handle simple one is pushed away downwards, makes container change the state that preparation is toppled over into from heated condition, and the mobile of handle is switched on or switched off supply of electric power.If handle also can be operated the cover plate of Hu Zui, this makes container need before the electric current supply heating element heater, and the spout lid plate is in closed condition and is easy to reach.

Also preferred supply of electric power to heater is a wireless type, so that container is raised more easily.Preferred type is that the supply of electric current and the relative bearing of container and base have nothing to do, for example the type of describing among the W095/08204.Such advantage is container and base not to be needed to align before may very heavy container putting down.

The container heater can adopt any form, submersible heater for example, or more preferably be arranged on the container base or heater on every side.Most preferably a kind of thick film screen printing heater that is called as is molded on the container base, or is moulded on the plate of a container base part at least.Such layout is known, for example, and in W096/18331.

Control to container can be adopted some forms.Can imagine that it can only comprise a boiling control, closes heater when liquid in containers is seethed with excitement.Preferred type is that it is remained on the temperature that needs.Announce among such suitable W097/04694 of being controlled at.It preferably includes: cut off the device of electric current, be used for may occurring overheated the time when heating element heater, this may take place when being energized without any liquid in the container.Further preferably: this control be made into one be installed in container base below.In a preferred embodiment, operable this type is controlled to have generally among the W095/34187 and describes.

One embodiment of the present of invention example with reference to the accompanying drawings is described, wherein:

Fig. 1 illustrates according to electric liquid heating vessels of the present invention.

Fig. 2 illustrates the profile of the electric liquid heating vessels of Fig. 1, and handle places " opening " position.

Fig. 3 illustrates the profile of the electric liquid heating vessels of Fig. 1, and handle places the off-position.

Electric liquid heating vessels shown in Figure 1 has the kettle body 2 of the double-walled of a molded plastics, has 4 and kettle mouths 6 that form in open top of a lid, in order to topple over content.As seeing from Fig. 2 and Fig. 3, groove handle 8 is molded in the bottom of container kettle body 2, and the user can be placed in one the finger of a hand so that the part support to be provided when mentioning and topple over.The edge 10 of handle is round, so that its hand to the user is comfortable as far as possible.Another handle 12 is installed in the top of container, and remaining required support is provided.Container 1 is placed on " wireless " base 14, and one is called 360 ° of connectors, 26 surfaces mounted thereto.The base of container suitably has a matching connector 30, and the example of such connector is announced in W095/08204.

With further reference to Fig. 2 and 3, handle 12 is installed on the lid 4 that is contained in container kettle body 2 tops hermetically.Handle 12 around axle 16 shown in Figure 2 basic for vertical heating location (" on " position) with shown in Figure 3 can pivot between substantially for the dump position of level (D score position).Handle can be optionally be positioned in these positions any by knocker or other clips and keeps motionless.

Actuator 18 is fixed on the handle 12 or as the part of handle 12, acts on the upright terminal 20a that slidably is installed in the cover plate 20 that covers on 4, selectively closes or open to topple over kettle mouth 6.Similarly, this cover plate 20 can be an arc, when by one when elongate articles that cover plate 20 is in similar position promotes, can pivot covers opening.Excessive steam is selected when having avoided heating like this.When liquid is heated to needed temperature as after its boiling, handle 12 can be rotated counterclockwise (shown in Fig. 2 and 3) so that cover plate 20 withdrawal is toppled over kettle mouth 6 thus and opened.This withdrawal action can realize by for example effect spring (not shown) on the cover board.

Heater is installed in the bottom of container, for example a track heater that is installed on the corrosion resistant plate 24.Described among the heater that is fit to such as W096/18331 and the W097/04694.Be control piece 28 below this base, be used for when the liquid boiling of container or owing to when not having liquid but to connect the caused overheated heater of switch in the container, cut off supply of electric power.In the previous case, it can be converted to one " boiling control slowly ", and slower ground heating liquid is to keep it within a given temperature range.The example of this control is published on the Patent Cooperation Treaty publication W097/04694.Control piece 28 can have a mechanism of crossing the center as a micro switch, and its connection by being fit to is separated automatically by the effect of rod 22 downward pressures that provide.The end 22a of rod passes through the flexibly part of push handle 12 of a disc spring (not shown).Handle 12 from its " on " can promote rod 22 to the rotation of its D score position and unclamp the mechanism that this crosses the center downwards, disconnect heater thus.Alternative, push rod can act on the sheet spring, and it is in a pair of contactor one, thereby cuts off contact.

Therefore in order to topple over the content in the container, handle 12 at first from its " on " position moves to the D score position.Open kettle mouth 6 and cut-out supply of electric power to heating element heater.It can be used for container is mentioned and poured out its content from corresponding electric current supply base 14 subsequently.The user puts into groove 8a with the finger of a hand, and the another hand is used for catching up knob 12.Container can cosily be mentioned and be toppled over to pour out liquid now.In the toppling process, weight almost is supported along the inner surface 8b of groove 8.At the area of mentioning and especially provide when toppling over relatively large support vessels weight, guarantee to increase the convenience of two kinds of operations, this may be boiling hot fluid operated in remarkable advantages is arranged.

Described a special embodiment herein, use of the present invention is not limited to this embodiment.Those skilled in the art will find, do not break away from spirit of the present invention and can make many distortion.For example, it is retractible to it is contemplated that in the handle one is made for, and with the same plane of main body, under such situation, when the content of container enough heavily needs two one or two portable time-outs, just need pull it use.Cover plate can slide with hand propelled and unclamp by the button on the handle by overcoming elastic force, to avoid contacting of user's hand and steam.The present invention also can implement having to describe in the liquid heater of different controllers and heater with these.For example, container can use the control type of describing among the W095/34187.Except shown in connection the push rod can be used for the motion of handle is passed on the controller.And power cut-out switch can become and following handle links, and is controlled by the user when the user promptly descends handle.
