Definitions
- the invention relates to a locking device for locking the door Household appliance, in particular a household appliance operated at high temperature, with a through a bimetallic drive between an opening and a Closed position and vice versa movable locking member according to the preamble of claim 1.
- Bimetal controlled locking devices for domestic appliance doors are for example known from DE 37 09 660 C2 and EP 0 347 592 A1. With these Locking devices is as a drive for the hand-operated locking member in the locking position locking slide a bimetallic Snap disc provided. This bimetallic snap disc ensures on the one hand when heating up for a sudden blocking of the closure the gate valve. After such a block, the Heating current for the bimetallic snap disc. This jumps due to its cooling back to its open position.
- FR 1 581 402 A is a locking device for locking a motor vehicle door with an adjustable between two positions by means of two bimetals Actuator known.
- a tilting mechanism acts on the actuator, that keeps the actuator bistable in both positions and that the actuator moves to the other position as soon as it through one of the bimetals from the previous position over a dead center is driven.
- DE 196 01 228 C2 describes a sealing device for the door a washing machine or dishwasher is known in which a locking body between a closed position and an open position is adjustable.
- the locking device has a bistable adjustable by a magnetic drive Element that locks the locking body in a first position and releases in a second position.
- Locking device simple and therefore economical to manufacture. she should be able to be realized in a space-saving manner, also with the freedom of design for the Do not restrict device design. After all, their operation should save energy and environmentally friendly, e.g. be quiet.
- the bimetallic Drives directly control the locking and unlocking movements and not just the mobility of the locking member in the closed position locking gate valve. Energy consumption only falls during the Switching process on and there only to cope with the first part of the Locking or unlocking movement until the dead position is exceeded of the toggle. After that, the toggle not only takes over second part or the completion of the displacement movement or the switching process but also preferably switches off the electric bimetal heating. The functional system is therefore from the dead point of the toggle mechanism is de-energized and the locking or unlocking position is still stable. Both the locking movement and also controlled the unlocking movement. The final state reached, that is Locking and unlocking positions are stable. It is a matter of an overall bistable system.
- the coupling bridge and locking slide encapsulate the toggle mechanism between them, which is also shielded from the bimetal drive. Carry out all movements of the functional parts of the locking device itself in the longitudinal plane of the housing. This also makes it easier to install Construction.
- a locking slide 2 in the transverse direction 3 between its unlocked position (Fig. 2) and a locking position (Fig. 3) mounted longitudinally. He assigns the Outline shape of a T standing on its head and stands with both of them Horizontal ends 4,5 of the T-transom as well as with the free vertical end 6 of the T-longitudinal beam through housing openings 7 in the side walls of the Lower housing part 1 to the outside.
- the ends 4-6 are the drive ends of the locking slide 2, for locking purposes with door-side locking elements 8 immediately (Fig. 5,6) or via intermediate Transmission elements 9 e.g. act indirectly in the form of a swivel lever.
- the Locking elements 8 are e.g. Part of an appliance door to be locked.
- Bimetals 10,11 Approximately perpendicular to the transverse direction 3 there are two within the lower part 1 of the device Bimetals 10,11 arranged. They are designed like stripes.
- the stripe plane runs at right angles to the plane of the drawing of FIGS. 1-4.
- the stripe levels run parallel to each other and keep a certain lateral distance between them on.
- the bimetals are fixed on the housing side with their foot ends 12, 13. There are they are firmly welded to the contact tongues 14, 15, which are in slots 16 inside the housing side wall 17 lie fixed and with their contact ends from the Protect the interior of the housing from the outside (Fig. 2,3).
- the bimetals 10, 11 engage with their movement ends 18, 19 in the transverse direction 9 sliding locking slide 2 indirectly. This is indirectness however only to the extent that between the ends of the movement 18, 19 the Bimetals 10, 11 and the actual locking slide 2 a coupling bridge 20 is interposed, which, however, by its positive engagement 21 in the locking slide 2 and by their drive-like interaction and their parallel position to the locking slide 2 functionally as part of Locking slide 2 can be seen.
- the two-part design of coupling bridge 20 and locking slide 2 has i.a. manufacturing or assembly reasons.
- the two bimetals 10, 11 form together with the locking slide 2 or its coupling bridge 20, so to speak, the two vertical legs and the saddled horizontal leg of one of the Greek Letters ⁇ corresponding overall structure.
- the locking slide is 2 or the coupling bridge 20 to the movement ends 18, 19 of the two bimetals 10.11.
- the two bimetals 10, 11 thus act like the two pillars of a bridge head as supporting parts for the coupling bridge 20, the longitudinal guidance of the housing base 22 and the housing cover 23 as Side guides is effected when the housing is in its final assembly state located.
- This mounting or mounting of the coupling bridge 20 is special low-friction and therefore also energy-saving.
- the bimetals 10.11 stand with their movement ends 18, 19 in recesses 24 on the side facing them Flank of the coupling bridge 20 into it.
- the recesses 24 have the Function of a cutting edge bearing (Fig. 4). They also form through their transverse walls a shift lock for the movement ends 18, 19 of the bimetals 10.11.
- the coupling bridge 20 therefore hovers freely on the bimetal ends 18, 19 and is guided by the bimetals 10, 11 alone. No one is needed additional guidance of the displacement movement of the coupling bridge 20 within of the housing 1, although such guidance through the housing base 22nd or the housing cover 23 should not be excluded.
- the coupling bridge 20 is practically attached to the ends of the bimetals 10, 11.
- the coupling bridge 20 is connected to the locking slide 2 by a loose positive engagement 21. This transmits the drive movement the bimetals 10, 11 on the locking slide 2, but without on the locking slide acting bearing pressures on the coupling bridge 20 and thereby indirectly to the bimetals 10, 11 and thereby approximately their functionality to influence or impair.
- the coupling bridge 20 is between the two recesses 24 for the ends of the movement 18.19 of the bimetals 10.11 or between their pins for one Positive engagement 21 on the locking slide 2 on the locking slide 2 facing side hollowed out (trough 25).
- the locking slide 2 contains on the coupling bridge 20 side with the trough 25 corresponding counter trough 26.
- the troughs 25, 26 enclose a cavity, in which a housing projection 27 protrudes from the housing base 22.
- the housing projection 27 forms the housing-side support of the tilt spring 28, the bottom 29 of the trough 25 of the coupling bridge with its lower end 20 acted upon.
- the toggle spring 28 forms the energy store of a toggle mechanism, which 2 and 3 is shown in its two tilt positions, on the one hand the locking position (Fig. 3) and on the other hand the unlocking position (Fig. 2) form.
- the rocker spring 22 acts on the coupling bridge 20 in the transverse direction 3 such that their ends either on the left side wall 32 (Fig. 3) in the locked position or on the right housing wall 33 (Fig. 2) in the unlocked position.
- This housing system causes a voltage-independent positional stability of the coupling bridge 20 or the Locking slide 2 in the locked position (Fig.
- the housing projection 27 is also part of the housing side Longitudinal guide for the locking slide 2, as that of FIGS. 1-3 is clearly recognizable.
- the toggle spring 28 holds the coupling bridge 20 in all positions securely on the movement ends 18, 19 of the bimetals 10.11.
- the coupling bridge 20 is supported on the drive ends 18, 19 without any friction of bimetals 10.11. This edition is stabilized by that between the two Drive ends 18, 19 from above acting on the coupling bridge 20 rocker spring 28.
- the guidance of the locking slide 2 or the coupling bridge 20 within of the housing 1 can otherwise be accomplished through the housing walls be also the end stops for the mutual sliding movements form.
- the active sides of the thermal bimetals 10, 11 face one another (Fig. 4). They are heated by PTC resistors 34, 35.
- the PTC's 34.35 are connected to voltage via the contact tongues 14a and 39 or 15a and 39. 2, the contacts 14a, 39 on When voltage is applied, the PTC resistor 34 heats up and the bimetal 10 swings out with its end of movement 18 counterclockwise. This Swiveling movement becomes very low-friction via the coupling bridge 20 onto the locking slide 2 transferred to the locking in the transverse direction 3 after is moved to the left.
- the movement distance up to the stop of the coupling bridge 20 on the housing side wall 32 is divided into two sections of approximately the same length.
- the warming of the PTC's 34 caused by the deflection of the bimetal 10 pivot drive required in this movement section also causes the compression of the rocker spring 28 until whose longitudinal axis has reached the dead center, in which it is approximately perpendicular to the transverse direction 3, that is oriented vertically with reference to FIGS. 2 and 3.
- By walking through the dead center expands the rocker spring 28 and thereby takes over further displacement drive for the coupling bridge 20 or for the locking slide 2 regardless of the heating of the PTC's 34.
- the control of the signal contacts 42 of a signal device is also carried out by the coupling bridge 20 accomplished. Depending on their position, therefore, from the outside the system status can be recognized at any point.
- the advantage of the locking device is the extremely small dimensions the unit.
- a stroke of, for example, 3 mm of the locking slide 2 is sufficient to lock the mechanics.
- the bistability of the two positions (Locking and unlocking position) is guaranteed.
- the current one Position of the locking slide 3 is independent of any power failures and it remains.
- the drive remains in its starting position, if a voltage failure occurs during the switching process.
- Voltage is only present during the switching processes for locking and unlocking Bimetal or at the PTC.
- the bimetals and PTC's are only slightly thermally stressed, so that they ensure a long service life.
- the system works silent in contrast to a magnetic drive.
- the system unlocks automatically when connected to voltage.
- the energy requirement is very low. He is approx. 1 A over max. 2 sec at 230 V. Also lower voltages than the nominal voltage 230 V are sufficient for full functionality without any problems. It does not apply in other systems, e.g. Linkage necessary for a motor drive, because the locking
