Definitions

  • the invention relates to an electrical household appliance arrangement with a stand receiving an electrical contact arrangement and a connecting line and with a hand-held device which can be placed on the stand and which engages with a contact device in the contact arrangement when placed on the stand, the circuit of the hand-held device being interrupted when contact is made.
  • Such a household appliance arrangement is designed as an electric kettle, as an iron, as a blender or as a similar device.
  • the handheld device itself has no electrical connection line, which is desirable in many cases for reasons of easier handling.
  • the hand-held device must always be in the switched-off state when it is placed on the stand and also when it is lifted off the stand, on the one hand to prevent undesired switching operations and on the other hand to prevent electrical flashovers, arcing or the like when contacting and disconnecting the plug pins to avoid. This is difficult to ensure mechanically.
  • the object of the invention is such a design of the electrical household appliance arrangement that the hand-held device is always automatically switched to the switched-off state when it is placed on the stand and especially when it is lifted off the stand, so that the circuit of the hand-held device is interrupted when the contact device is placed in the Contact arrangement engages or the contact device is separated from the contact arrangement when lifting.
  • the hand-held device has a switch with the switching element of which at least one switching cam is coupled, which interacts with a switching profile of the stand in such a way that the switch always moves to the switched-off position at the start of the mounting movement and the lifting movement of the hand-held device becomes.
  • the invention differs from the prior art in that the placement and lifting movement of the hand-held device inevitably leads to the device being switched off before the contact device comes into electrical contact with or is separated from the contact arrangement.
  • the contact arrangement is always assembled with an open circuit, so that no sparking or welding by a current flow or arc is possible when making contact. This applies above all to the contact separation during the lifting movement, since the lifting of the filled hand-held device can take place slowly under certain circumstances, so that an intense arc can occur.
  • the circuit of the hand-held device is always interrupted when contacting or separating contacts between the contact device and the contact arrangement. This switching of the circuit inevitably takes place during the touchdown movement and during the lifting movement.
  • the switching profile has an inclined surface inclined to the mounting direction, which cooperates with a nose of the switching cam. This results in a forced switching movement when touching down.
  • a symmetrical and tilt-free actuation of the switch of the hand-held device is ensured in that the switching cams sit on an actuating rocker coupled to the switching element of the switch, on which an actuating rod of the hand-held device also engages.
  • a button coupled to the rocker switch has at least one leg with a nose which interacts with the switching profile of the stand. This results in a rigid coupling between the switching profile and the rocker switch and thus a safe switching function.
  • the invention provides that two legs sit parallel to each other on the push button and that the stand has two correspondingly aligned switching profiles which switch the push button to the off position when the handset is placed and lifted off. This pair of legs ensures a tilt-free circuit.
  • the lugs and the switching profiles each have a triangular profile with profile edges that are inclined against one another.
  • the switching path can be kept small by making the angle of the profile flanks as large as possible in relation to the direction of the mounting and lifting movement, self-locking being avoided.
  • the circuit is immediately interrupted, especially when the handheld device is lifted, so that the occurrence of an arc is impossible.
  • the invention provides that the contact arrangement is designed to be resilient in the direction of the mounting movement. This results in large switching paths for the contact pieces, so that the switching profile ensures that the internal circuit of the household appliance is safely switched off before contacting or disconnecting.
  • the invention further provides that the contact arrangement has movable contact pins which are biased in the lifting direction by springs.
  • the stand 1 shows a section of an essentially round stand 1 which contains an electrical connection line (not shown) and an electrical contact arrangement with a plurality of resilient contact tongues 2.
  • the stand 1 has a peripheral edge with an inner inclined surface 4, which also has a plurality of slots 5, into which the plug pins of the contact device 8 enter. 1, the contact tongues 2 are depressed against their spring force. The spring force also provides the contact force.
  • a hand-held device is designed as a pot-like container 6 with a handle 7.
  • a contact device 8 with a plurality of plug pins which give a connection to a heater 10 via a switch 9.
  • the switch 9 is operated by means of a slide or a rocker switch 11, which can be moved by an operating rocker 12.
  • a switching rod 15 is coupled to the operating rocker 12 or the switching cams 13, which can be operated by means of a button 16 in the handle 7.
  • Each nose 14 has an edge 17 which cooperates with an end wall 18 of a slot 5.
  • the end wall 18 is therefore effective as a switching profile.
  • a thermostat element 19 is provided for a forced, temperature-dependent switching of the switch 9.
  • Fig. 1 the switch-on state of the switch 9 and the switching cams 13 is shown in dash-dotted lines.
  • the nose 14 of each cam 13 extends far into the slot 5.
  • the connector pins of the contact device 8 are in engagement with the contact tongues 2.
  • the switch 9 can be switched on and off as desired via the key 16.
  • the switching cams 13 are adjusted.
  • the switch 9 When the water container 6 is inserted into the stand 1, the switch 9 is also forcibly switched off, regardless of the respective position of the switching cams 13, since the lugs 14 abut the inclined surface 4 and are thereby pivoted clockwise, so that the switch 9 is switched off becomes.
  • the switch-off takes place before the plug pins of the contact device 8 come into engagement with the contact tongues 2.
  • the stand 51 contains a contact arrangement in the form of contact pins 52, which are each biased in the switch-off direction by a helical compression spring 53.
  • Each contact pin 52 is connected to a connecting line 55 via a contact shoe 54.
  • the connecting line 55 can be moved and moved together with the respective contact pin 52.
  • a container 56 in the form of a kettle has a contact device 58 with a plurality of contact pins corresponding to the number of contact pins 52.
  • the contact arrangement of the contact pins 52 is accommodated in a housing 57, which is not explained in detail.
  • At the side of the housing 57 there are two rectified switching profiles 70, each with two profile flanks, each forming a triangular profile and at a comparatively large angle, i.e. are inclined at almost 90 ° with respect to the direction of the landing and lifting movement. The angle is chosen so that self-locking is reliably avoided.
  • the contact device 58 is seated at a switch 59 which switches the circuit of a radiator 60.
  • the switching takes place by means of a rocker switch 61 on which an operating rocker 62 sits.
  • the actuating rocker 62 carries a button 69 which protrudes from a cover housing 71 of the container 56.
  • Two legs 72, each with a lug 64, sit parallel to one another on the button 62.
  • the lugs 64 each interact with the flanks of the switching profiles 70.
  • the cover housing 71 has a guide sleeve 73 on the foot side, which ensures precise guidance of the contact parts and switching profiles.
  • Fig. 3 shows the button 69 in the on position.
  • the guide sleeve 73 ensures precise guidance.
  • An edge of each tab 64 abuts the top edge of a switch Profiles 70 on, so that the push button 69 and the rocker switch 61 are pivoted clockwise with respect to Fig. 3 in the off position during the further mounting movement.
  • the internal circuit of the kettle is interrupted, so that the contact pieces of the contact device 58 come into engagement with the contact pins 52 in the de-energized state.
  • the button 69 can be switched in any direction, so that the internal circuit of the kettle can be switched on and off.
  • the function of the thermostat switch is not further explained here.
  • the lugs 64 engage with the lower flanks of the switching profiles 70, as is shown in broken lines in FIG. 4.
  • the edges or profile flanks of the lugs abut the lower profile flanks of the switching profiles 70, so that the button 62 is pivoted clockwise and the switch 59 is thereby switched off, so that the internal circuit of the kettle is interrupted before the contacts of the Contact device 58 are lifted off the contact pins 52.
  • the switching path is therefore smaller than the path of the contact break.
