Description

Flatiron

The present invention relates to a kind of electric iron as described in the preamble according to claim 1.The present invention also relates to a kind of method of assembling flatiron.

Prior art JP 03-193098A discloses a kind of flatiron that has a shell, at this flatiron a power line is installed with getting on tensile load.A square holding element is sandwiched on the power line.When being in confined state, square holding element rests on two laths that stretch out on the shell.The electric connection of power line is designed to annular cover hook, and this cover hook relies on and contacts the electrical connection of tonguing row on screw and the soleplate.According to prior art, be connected with the electric connection conduction in order in a flatiron, to go to tensile load ground that power line is installed, two and half shells of at first square fixture must be clipped on the power line.Next, at first first annular contact is overlapped hook, and second annular contact cover hook can rely on a screw to be screwed to corresponding the contact on the tongue on the soleplate respectively then.At last, square fixture can insert the back of two security strips that stretch out on the shell.This known power line go tensile load connection and power line and soleplate be connected electrically in assembling the time be not very easy.Power line goes tensile load to be connected with soleplate and is electrically connected with the difficult installation step of many necessity.

For electric iron, task of the present invention is to make power line and flatiron simply go tensile load to be connected and be electrically connected.

This task solves by first electrical contact on the power line is rigidly fixed on the fixed mechanism that is used to make power line remove tensile load on the electric iron of the described type of beginning.

Because rigidity is rigidly fixed on the fixed mechanism in order to remove tensile load for the electrical contact of power line, one section fixed range in the first electrical contact space and leave one section fixed range ground of fixed mechanism and locate.First electrical contact on the power line especially can be simultaneously be connected with second electrical contact conduction on the flatiron.The simplification of assembling process is can carry out being connected of the electrical connection of electrical contact and fixed mechanism and flatiron in the assembling process simultaneously in a step.Assembling process is only through several steps seldom and just can finish in a short period of time.

In preferred design of the present invention, first electrical contact relies on the first plug-in unit space distance of a design on fixed mechanism to rigidly fix.By using by a non electrically conductive material plug-in unit making of plastics preferably, first electrical contact is electric insulation each other not only, and rigidly fixes with the distance of determining each other.When plug-in unit directly designed on fixed mechanism, the position of electrical contact was also fixed with respect to fixed mechanism.Such advantage is, clamped and plug-in unit is inserted into or is placed on the electrical contact on the flatiron by fixed mechanism, just can install electrical contact.

In a favourable design of the present invention, second electrical contact is installed on second plug-in unit with the first plug-in unit complementation, especially at the rear portion of base plate.If for example Gu Ding contact tongue space is arranged on the sole plate apart from ground, on second electrical contact, be equipped with a plug-in unit with regard to unnecessary.Because second electrical contact rigidly fixes on sole plate, they are just clearly located and make first plug-in unit that has first electrical contact directly to insert.Yet if be not provided with fixing contact tongue on the sole plate, but there is flexible electric wire the there, and second electrical contact can rely on their plug-in unit space to determine location, distance ground so.At this moment, can be equipped with second plug-in unit with the first plug-in unit complementation, this plug-in unit has second electrical contact.Second plug-in unit preferably is installed in the rear portion of base plate.By making second plug-in unit be positioned at the rear portion, first plug-in unit that is connected with power line can simply be inserted on second plug-in unit.

Second plug-in unit can be electrically connected accessibility primary importance and rotates to and make fixed mechanism be fixed on the second place on the flatiron with removing tensile load from one for setting up with first plug-in unit.Usually, the power line of electric iron vertically upward stretches out shell substantially at the rear portion of flatiron.As making power line go the fixed mechanism of tensile load must be fixed on the flatiron, preferably on the shell of flatiron, to realize going tensile load.Electrical contact is difficult to approaching at this embedded location usually.In order to improve accessibility, second electrical contact on the soleplate especially, second plug-in unit that has second electrical contact can rotate to primary importance, can arrive in this position to set up and being electrically connected of first plug-in unit.

Second plug-in unit can rotate up the second place from primary importance around a rotation that is parallel to base plate plane.In primary importance, second plug-in unit can enough reach to set up and being electrically connected of first plug-in unit.If second plug-in unit is arranged in the rear portion of base plate, second electrical contact on second plug-in unit can be distinguished from behind or from top approaching, will be approaching especially easily so.Be connected the second place on the flatiron at fixed mechanism, the best directed in orthogonal of second electrical contact on second plug-in unit upwards with removing tensile load.In this second place of second plug-in unit, first plug-in unit is above vertical direction is positioned at second plug-in unit.The fixed mechanism that is used to make power line remove tensile load is with first plug-in unit is vertical is connected.Power line is drawn from shell on the top of flatiron.Can be provided with a ball-and-socket joint or swing hinge at the outlet of power line from shell.By the layout up and down of second, first plug-in unit and fixed mechanism, power line is not had is guided out flatiron more bendingly.Because power line has only very little bending, so power line only bears very little mechanical load, and prolonged its service life.

Angle between second plug-in unit is preferably spent with one 30 to 60 rotates to the second place from primary importance.To the anglec of rotation situation between 60 degree, second plug-in unit should be an angle that is between the horizontal and vertical position in the orientation of primary importance at one 30 degree.Owing to be in such position, second plug-in unit that is used to assemble is approaching especially easily.First plug-in unit since guiding movement can be not only soon but also be easily inserted on second plug-in unit.

In a good especially flexible program, second plug-in unit is supported on the bearing that is fixed on the base plate.If second plug-in unit is bearing on the bearing, then desired the rotatablely moving of second plug-in unit can guarantee reliable especially and safety.

If bearing has two axle journals in the opposed grooves that is embedded into second plug-in unit with regard to advantageous particularly.Second plug-in unit can be around the axis rotation of axle journal.Second plug-in unit not necessarily must be equipped with bearing on the groove that is halved together of axle journal.If second plug-in unit has the hole that can embed two axle journals on the bearing just enough in relative both sides.But it is favourable being provided with opposed groove on second plug-in unit, because groove has certain longitudinal extension, second plug-in unit not only can rotate on the axle journal on the bearing thus, and can carry out moving to a certain degree in the vertical.Advantage wherein is that relevant with size with the position of first and second plug-in units or relevant with size with the position of fixed mechanism manufacturing tolerance can be compensated.

Second plug-in unit can have at least one holding flange, and this holding flange can enough reach second plug-in unit at one and act on the bearing to set up the primary importance that is electrically connected with first plug-in unit, and makes second plug-in unit remain on this primary importance.Holding flange is used for making second plug-in unit to be fixed on the bearing.Rely on holding flange, second plug-in unit is securely held on that position that is electrically connected with first plug-in unit.The design of holding flange is convenient to produce a confining force with bearing, and this confining force prevents that second plug-in unit is owing to deadweight is dropped.On the other hand, confining force should only be convenient to second plug-in unit and just can rotate to fixed mechanism from primary importance with moderate energy consumption and be connected the second place on the flatiron with removing tensile load.

In a more favourable design of the present invention, an operation indicator is installed on fixed mechanism and/or is designed an electric connection that is used for operation indicator.For example, a clamper that is used for electric light can design at fixed mechanism.In a flexible program, operation indicator can be installed on the fixed mechanism.In another flexible program, operation indicator can be installed on the shell of flatiron, and the electric connection of operation indicator can be connected with the electrical contact on the fixed mechanism thus.In two flexible programs, advantage all is that operation indicator is without any need for independently conducting electricity connecting line.The assembling of the power line by removing tensile load, the electrical connection of not only having connected soleplate, and connect the electrical connection of having gone up operation indicator simultaneously.This has further simplified the assembling of flatiron.

According to the design of electric iron, fixed mechanism can or be fixed on the shell, or is fixed on the base plate.Fixed mechanism preferably is fixed on the part of shell.Yet, also can make sole plate be equipped with a special bearing, fixed mechanism can be fixed on this bearing.

In a favourable design of the present invention, shell or base plate have a retained part, and fixed mechanism has a guiding parts corresponding to retained part.The guiding parts of this fixed mechanism is placed on the retained part on the shell for example.

Be placed on the retained part by guiding parts, fixed mechanism just links to each other with shell or base plate respectively.This design make fixed mechanism can with shell or base plate reliably and go to tensile load ground to go up in succession.

Retained part can have a seat that is used to accept screw, and this is used for lid removably connecting on shell or base plate.This seat can be designed to an inwall, or is to have a hole at least, can be screwed into a tapping screw.Lid is preferably with the stop mechanism that is used for fixing fixed mechanism.Fixed mechanism is fixed on a pretension position on the shell by stop mechanism.Thereby fixed mechanism is not to be fixed on the shell separately, but is fixed on the shell with lid.

By stop mechanism of the present invention, not only can save one and be used for fixing mechanism and be fixed to independent screw on the shell, and extra assembling process of a step has not needed yet.

Stipulate in the assembly method of flatiron of the present invention, in the first step, first electrical contact on power line is electrically connected with second electrical contact on the flatiron, in second step, second electrical contact is fixed on the base plate swingably, and in the 3rd step, first electrical contact rotates towards base plate or towards shell.In a preferred embodiment of the invention, first electrical contact is fixed on first plug-in unit and second electrical contact is fixed on second plug-in unit.Assemble for flatiron according to this preferred embodiment, first plug-in unit that links to each other with power line is inserted in second plug-in unit that is electrically connected with base plate, and in other words, a plug-in unit inserts in another complementary plug-in unit.Then, second plug-in unit is hinged on the bearing that is fixed on the base plate.In the 3rd step, first plug-in unit together with second plug-in unit towards the rotation of the shell of flatiron and be fixed on the there.The fixed mechanism that is used to make power line remove tensile load links to each other with second plug-in unit.By rotate first and second plug-in units towards shell in the 3rd step program, the fixed mechanism that is used to make power line remove tensile load is also rotated towards shell.Fixed mechanism can be connected with shell subsequently.This preferably occurs in the 4th step program, is used to make first electrical contact to be fixed on one of shell or base plate in this step and determines that a locational lid is fixed.Not only lid is fixed on the shell by this 4th step program, and fixed mechanism also can be fixed on the shell by this 4th step program.

Stipulate in another selectable assembling process that in the first step, second electrical contact on the flatiron can be hinged on the base plate, in second step, first electrical contact on the power line can be electrically connected with second electrical contact, and in the 3rd step, first electrical contact rotates towards base plate or towards shell.In preferred design of the present invention, first electrical contact is by the first plug-in unit fixed position, the position and second electrical contact interfixes in second plug-in unit of complementation.Second plug-in unit preferably is hinged on the bearing that is fixed on flatiron or the base plate.In the second step program, preferably linking to each other with fixed mechanism is inserted into first plug-in unit with first plug-in unit that removes tensile load, thereby has set up electrical connection between first and second electrical contacts.In the 3rd step program, second plug-in unit and first plug-in unit are respectively to base plate or shell rotation.If first plug-in unit links to each other with fixed mechanism, second and first plug-in unit can rotate by the rotation fixed mechanism.At the terminal point of rotating distance, the fixed mechanism that has a guiding parts leans against on the retained part on the shell.In the end of the 3rd step program, fixed mechanism is positioned at a position that is fixed on the shell.In selectable the 4th step program, the lid that is used for making first electrical contact respectively or first plug-in unit is fixed can be connected a definite position on shell or the base plate.Be capped shell and be closed by lid being fixed on the shell not only electrical contact, and fixed mechanism thus lid be fixed on the shell.

The assembly method of flatiron of the present invention makes the power line of flatiron realize being electrically connected and going tensile load by several simple installation step.This has not only shortened installation time, and has reduced the number of part.Such advantage is that cost is more saved in the manufacturing of flatiron of the present invention.

The present invention includes prior design, this design is arranging thermal resistor usually and importing the flatiron rear portion that is used for making the metal base plate heating heat, to be provided with a special-purpose escapement at metal base plate with between to heat sensitive plastic casing.This escapement can be used for supporting the connector between two primary clusterings of flatiron simultaneously.In detail, for this purpose, it is screwed into metal base plate on the one hand, is screwed into plastic casing on the other hand.Escapement is because its big relatively elongation produces a large amount of heat radiations, and/or because its limited thermal conductivity is served as the Thermal packer between metal base plate and plastic casing.

In a further advantageous embodiment, geometrical clamp or make, or make, preferably an injection-moulded plastic part by a kind of high-quality heat resistant plastice by a kind of metal with less (promptly for metal) thermal conductivity.

In a preferred design, from vertical view, geometrical clamp has trapezoidal shape basically, and for example the junction of an end and metal base plate is similar to a rectangular flat, and the junction of the other end and plastic casing is a wide metallic plate.Be used to guide the recess of electric wire preferably to be located at middle.

In side view or in longitudinal sectional view (with respect to the use location) respectively, the flat board of base plate one side connects and is connected with the lath of shell one side all is horizontal location, and they are interconnected by the connector that rises to the rear portion from base plate obliquely, have formed the basic configuration of " S " that be similar to an elongation substantially.From the angle of heat, with the tie point of plastic casing (laterally) and the vertical metal base plate of going up away from heat in the horizontal direction.

As the continuity of the present invention design, be provided with one second geometrical clamp as another fixed mechanism and simultaneously again (to a certain extent) as Thermal packer, this geometrical clamp links to each other with plastic casing with metal base plate near the flatiron front end.Because the common structure of flatiron, the latter can not be designed to stretch very longly and its heat radiation effective not as first geometrical clamp, so it is best at the stubborn screw thread place of plastic casing with the combining of spacer that the high-quality heat resistant plastice is made.

A remarkable advantage of proposed solution is, plastic casing can be by only being that medium heat-resisting thereby plastics cost economy are made, for example polypropylene.Plastic casing is effectively heat insulation for metal base plate, particularly at its rear portion, makes that its service life is elongated.Provide long metal intermediate plate to be to plastic casing as the result of fixed mechanism, because the elasticity of geometrical clamp, the comfortableness of flatiron increases to some extent, and the resistance to impact of whole flatiron has improved in addition, and this is good characteristics in the required shatter test of passing through of for example U.S. and Canada.

In another decision design, first and/or second geometrical clamp has mesopore at contiguous screw hole place, and the spacer of plastic casing or insertion also has and is used for these mesopore being halved together to flange.By each geometrical clamp, this has guaranteed the accurate location of plastic casing with respect to metal base plate.
