Definitions
- the invention relates to a household appliance, having a chamber that can be closed by means of a door and at least one door monitoring device.
- the invention is particularly advantageous applicable to PEF ("Pulsed Electric Field") - cooking appliances and microwave ovens.
- doors of such household appliances are often monitored by microswitches. These switch off the device when the door is open or prevent the activation of certain operating states and work according to the same principle: the closed door mechanically actuates the micro-pressure switch installed inside the household appliance. In the actuated state (door closed), the contact of the switch is typically closed. When the door is opened, the switch is returned to its original position by spring force or gravity and thus opened again. The switching status of the micro pressure switch is queried by an electrical current via its internal switching contacts.
- the use of micro pressure switches is quite safe because, for example, in the event of a cable break, an open state is recognized and a short circuit of the connecting wires, which could simulate a closed switch, can be reliably prevented by constructive measures (e.g. suitable wire routing in the device) .
- the contacts of the microswitch can disadvantageously "stick” over time. This means that the contacts will not open when the door is opened.
- Such "contact adhesives" can have various causes, possibly also in combination:
- micro-pressure switches To reduce the risk of micro-pressure switches, two micro-pressure switches connected in series are often used, which are actuated together. It doesn't matter which of the two switches opens. The safety function is fulfilled very reliably. But if a contact sticks, the promised operational reliability depends on only one switch, namely the remaining switch. This situation can only be monitored by suitable additional electrical or electronic measures, e.g. by an additional separate logical link between the individual switches. However, these additional measures can also fail and must therefore be monitored separately.
- DE 102012222 152 A1 discloses a household appliance with a door and a door recognition device for recognizing a door state of the door, the door recognition voltage device has a capacitive sensor, the moving electrode of which is the door.
- EP 0456846 A1 discloses an electronic door lock for microwave ovens which is based on the principle of influencing coils to which high frequency is applied, the magnetic circuit of which is interrupted by the movement of the door.
- DE 38 170 75 A1 discloses a door safety switch for a household appliance, in particular a microwave oven with a microwave-tight closable cooking chamber, with an electrical switching element which can be actuated by a switch plunger angeord designated on the door of the device in the closed position of the door, the Switching element is arranged on a carrier element and the switching element is automatically adjusted during the Mon days by closing the oven door.
- US 2014197161 A discloses a door switch device for a microwave oven which deactivates the microwave system without separate “fingers” or pliers on the door surface having to reach into the main body of the oven in order to activate a switch.
- the switch uses stackable switches that are activated by a single switch lever.
- the switch lever is preferably made from a solid piece of ultra-high molecular weight (UHMV) polyethylene to maintain the accuracy of the angular measurements between the surfaces that touch the door hinge arm and the switch arm.
- UHMV ultra-high molecular weight
- a household appliance having a chamber that can be closed by means of a door and at least one door monitoring device with at least one pair of contacts, comprising two contact parts, one of which is the clock parts is arranged on the door and the other contact part is arranged on an immovable part of the household appliance.
- This household appliance thus uses a door monitoring device or "door safety device", which uses the mechanical connection between the mutually movable contact parts as a safety device.
- the two contact parts of the at least one contact pair do not represent components of a structural unit (e.g. a switch), but separate parts.
- the two contact parts of a contact pair only touch when the door is closed and then form an electrical connection.
- the user notices that the door cannot be opened and can switch off the device via the front panel of the device and / or call customer service. e) If a user opens a door that initially cannot be opened due to sticky contacts, using force and / or using tools (for example with a wooden spoon as a lever to open the door), the contact parts are torn from each other and thus separated, and the switching function is restored. In this case, for safety reasons, it does not matter if the device is defective afterwards, as its safety is maintained.
- a door opening can therefore always be reliably detected even with sticky contact parts, and a lack of contact with the contact parts when the door is closed does not lead to a safety-critical state.
- the contact part arranged on the immovable part of the household appliance can also be referred to below as the “immovably arranged” contact part, the contact part arranged on the door also as the “door contact part”.
- the chamber that can be closed by means of the door can be a chamber for the treatment of goods to be treated such as food and can also be referred to as a cooking chamber, oven chamber, etc.
- the at least one door monitoring device is connected to a circuit ("evaluation circuit"), the evaluation circuit being set up to monitor the contact state of the two contact parts of the at least one contact pair and to operate at least in a generally known manner a safety-critical device component (eg a magnetron or a PEF signal generator) if the at least one contact pair of the at least one door monitoring device is separated from one another.
- a safety-critical device component eg a magnetron or a PEF signal generator
- a pair of contacts can also be used directly in a circuit for supplying at least one device component, for example safety-critical.
- the door monitoring device can have only the at least one contact pair and possibly one or more electrical lines. When the contact parts are separated, the circuit of the safety-critical device component is also interrupted.
- At least two pairs of contacts can be electrically connected in series.
- the contact pairs can particularly advantageously be arranged in different areas of the door in order to be able to detect, for example, a levering open of the door at only one corner of the door or an open state (open or closed) of a warped or loose door in a particularly reliable manner.
- these can be separately connected to an evaluation circuit and / or in principle be connected or interconnected as required, e.g. electrically in series.
- the door monitoring device has exactly one contact pair. This enables a particularly simple and inexpensive design.
- each of the two contact parts of a contact pair is connected to at least one electrical line, e.g. for carrying a current (the measuring current or operating current), e.g. to an evaluation circuit of the household appliance, with the at least one electrical line of the door contact part leading through the door.
- This electrical line can be designed as a dedicated flexible line (e.g. a cable) or formed by metallic parts of the door itself, in which case the door hinge can take over the electrical connection to the rest of the household appliance.
- the immovable contact part has several (for example two) electrically separated contact surfaces and the electrical lines are connected to the several contact surfaces.
- the door contact part is like this designed that it electrically connects at least two of these contact surfaces of the immovable contact part in the closed state of the door.
- the advantage is achieved that the frequent mechanical bends in the line when the door is opened and closed causes it to break.
- Another advantage is that if an electrical consumer in the door (e.g. a control panel) is to be supplied, an unfavorable current lead to the door contact part via a dedicated line in the area of the door hinge, e.g. due to a lack of space, can be avoided.
- an electrical consumer in the door e.g. a control panel
- the door contact part for contacting the contact surfaces of the immovable contact part has corresponding counter-contact surfaces which are electrically connected to one another.
- the door contact part has an electrically conductive part, e.g. a metal part, the surface of which has the counter-contact surfaces. This is particularly easy and inexpensive to implement.
- the door monitoring device has two pairs of contacts, the door contact parts of which are electrically connected to one another.
- the two pairs of Schokon contacts are electrically connected in series with regard to the current flowing through them.
- This configuration enables an even higher level of operational reliability.
- the door monitoring device can be electrically connected exclusively via the immovable contact parts, for example to an evaluation circuit.
- a current conduction through the door to the contact parts located therein can also advantageously be avoided here.
- the immovable part of the household appliance is a door flange.
- This has the advantage that the immovable contact parts arranged there are particularly easy to design and assemble.
- the contact part (s) located in the door and thus the contact pairs (e ) are located on one side of the door, which are opposite a door hinge, in the case of a horizontally pivotable door with door hinge (s) below, for example on an upper edge of the door when it is closed.
- the door can also be a door that can be moved laterally or can be opened in some other way.
- the contact parts of a contact pair are designed as complementarily shaped plug-in elements of a plug-in connection or the contact pair forms a plug-in connection. This enables even more reliable contact to be made with the contact parts when the door is closed than when they are designed as flat contact surfaces. This is advantageous, for example, if the door or the frame has warped or the door has moved in relation to the frame.
- At least one of the contact parts of at least one pair of contacts that make contact when the door is closed has an annular groove. This provides a particularly inexpensive, robust and reliable possibility of contacting the contact parts of a contact pair.
- At least one of the contact parts has a predetermined breaking point.
- this contact part can advantageously be destroyed in a defined manner (eg break) and so eg its Interrupt the electrical connection to the evaluation circuit or the safety-relevant device component.
- the contact pairs can be used to supply consumers (e.g. operating elements, displays, etc.) with electrical energy in the door.
- consumers e.g. operating elements, displays, etc.
- the consumers can be connected to at least one electrical line connected to a pair of door contacts and supplied by the current flowing therein. If the door is opened, the power supply to the consumer is interrupted in a further development.
- any number of poles can in principle be secured.
- a two-pole fuse for simple power supply units and a three- or four-pole fuse for three-phase devices can be provided. This applies in particular if the contact pair (s) are built directly into a circuit for these device components.
- the contact parts or contact pairs are single-pole or single-pole protecting contact parts or contact pairs. It is a further development that the contact parts or contact pairs are multi-pole or multi-pole protecting contact parts or contact pairs.
- the household appliance is a PEF (“Pulsed Electric Field”) cooking appliance.
- the household appliance can also be a microwave appliance, e.g. a separate microwave appliance or a microwave / oven combination.
- any household appliance equipped with a door can be equipped with the door monitoring device described above. Service flaps etc. can also be equipped with it.
- FIG. 2 shows, as a sectional illustration in a side view, the household appliance from FIG. 1 with the door open;
- FIG. 3 shows a front view of a detail from a household appliance in the area of a door monitoring device according to a second embodiment with the door closed;
- FIG. 4 shows a front view of a detail from a household appliance in the area of a door monitoring device according to a third exemplary embodiment with the door closed;
- FIG. 5 shows, in an oblique view, a possible structural configuration of one of the two contact parts of the door monitoring device according to the second exemplary embodiment.
- FIG. 6 shows, as a sectional illustration in a side view, a sketch of contact parts hidden one inside the other when the door is closed, with one of the contact parts in an embodiment according to FIG.
- FIG. 1 shows a sectional side view of a simplified sketch of a household appliance 1, for example a PEF cooking appliance or a microwave appliance, with a treatment chamber for food ("chamber” 2), which is opened by means of a door 4 that can be pivoted about a door hinge 3 is lockable.
- the household appliance 1 also has a door monitoring device with a pair of contacts 6, 7, comprising a first ("door") contact part 6, which is arranged on the door 4, and a second ("immovable”) contact part 7, which is attached to an immovable Part of the household appliance 1 in the region of a flange 8 is arranged on.
- the two contact parts 6, 7 are each verbun with an electrical line 9 or 10, the electrical line 9 of the door contact part 6 leading through the door 4 and further into the body of the household appliance 1 in the area of the door hinge 4.
- the two electrical lines 9, 10 are connected to an evaluation circuit 11 of the door monitoring device.
- the evaluation circuit 11 is set up to recognize whether the two contact parts 6, 7 are connected to one another or not. For this purpose, for example, a voltage can be applied via the electrical lines 9, 10 and an associated current I can be recorded: if the current I flows, it can be concluded that the two contact parts 6, 7 are connected to one another, no current I can flow it can be concluded that the two contact parts 6, 7 - as shown in FIG. 2 - are separated from one another.
- the household appliance 1 can switch off safety-critical components of the household appliance 1 such as a magnetron, a PEF pulse generator, etc. or leave it switched off.
- the door monitoring device here thus comprises the two contact parts 6 and 7, the evaluation circuit 11 and the associated connection lines 9 and 10.
- the household appliance 1 can be operated safely under the following scenarios: a) If the previously opened door 4 is closed, the two contact parts 6, 7 touch each other in the normal state, and the closed state of the door 4 can be correctly recognized by the evaluation circuit 11 will. b) If the contact parts 6, 7 do not touch each other when the door 4 is closed - for example in the event of a fault - the evaluation circuit 11 falsely detects an open state, but this is not safety-relevant in the sense of monitoring the door 4. In such a case, the user can call customer service, for example. c) When the previously closed door 4 is opened, the two contact parts 6, 7 always separate from one another, and the open state of the door is correctly recognized.
- FIG. 3 shows a front view of a detail from a household appliance 12 with the door 15 closed.
- the household appliance 12 is designed analogously to the household appliance 1, but has two pairs of contacts 6, 7 and 13, 14.
- the pair of contacts 6, 7 is designed as in the household device 1, its immovable contact part 7 is also connected to the evaluation circuit 11 via the electrical specific line 10.
- the second pair of contacts 13, 14 analogously have a “third” door contact part 13 and a “fourth” immovable contact part 14, which is arranged in the region of the flange 8.
- Analogously to the first pair of contacts 6, 7, the door contact part 14 is connected to the evaluation circuit 11 via an electrical line 16.
- the first contact part 6 and the third contact part 13 are electrically connected to each other, for example via metallic components of the door 15 or, as shown, via a dedicated electrical line 17. Whether the door 15 is closed is detected by the evaluation circuit 11 that a current I flows through both (electrically connected in series) contact pairs 6, 7 and 13, 14. If only one of the contact pairs 6, 7 or 13, 14 is open, no current I flows Door 15, the case can thus be taken into account that a user forcefully bends the door open at one corner and then at least there the associated contact parts 6, 7 or 13, 14 are separated from one another. the.
- the door monitoring device has further advantages over the door monitoring device from Figure 1 and Figure 2:
- the evaluation circuit 11 is exclusively connected to the immovable contact parts 7, 14, so that an electrical line 9 through the door 15 or through metallic components of the door 15 can be dispensed with.
- Another advantage is that if an existing electrical consumer in the door 15 (e.g. a control panel, o is avoided via a line 9 in the area of the door hinge 3. A break in the electrical line 9 due to frequent mechanical stresses when the door 15 is opened and closed can also be ruled out.
- an existing electrical consumer in the door 15 e.g. a control panel
- the door monitoring device here comprises the contact parts 6, 7, 13 and 14, the evaluation circuit 11 and the lines 10, 16 and 17.
- FIG. 4 shows a front view of a detail from a household appliance 18 with the door 21 closed.
- the immovable contact part 20 has several (here: two) electrically separated contact surfaces 22a, 22b to which electrical lines 10 and 16 leading to the evaluation device 11 are connected.
- the door contact part 19 acts as an electrical (short-circuit) bridge between the two contact surfaces 22a, 22b, so that a current I can flow via the door contact part 19 between the contact surfaces 22a, 22b.
- the same advantages as with the household appliance 12 can be achieved even when only one pair of contacts 19, 20 is used.
- the function as an electrical bridge can be implemented, for example, so that the contact surfaces 24a, 24b of the door contact part 20 that can be contacted with the contact surfaces 22a, 22b are surface areas of an electrically conductive, e.g. metallic, component, e.g. a piece of metal.
- the mating contact surfaces 24a, 24b can be electrically separated from one another, as indicated, and connected to one another via an electrical line 25.
- the door monitoring device here thus comprises the contact parts 19 and 20, the evaluation circuit 11 and the connection lines 10 and 16.
- the immovable contact part 20 has an annular groove 26 and a central hole 27. In the area of the annular groove 26, the two contact surfaces 22a and 22b are present.

- Contact surfaces 22a and 22b are contacted by counter-contact surfaces 24a and 24b, respectively, with counter-contact surfaces 24a and 24b being electrically connected to one another, as indicated by line 25.
- This plug-in connection or coupling is particularly stable mechanically and enables reliable contacting of the contact surfaces 22a and 22b with the counter-contact surfaces 24a and 24b, respectively.
- the contact surfaces 22a, 22b can be present as annular contact surfaces in the annular groove 26, for example on opposite side walls.
- One of the Contact surfaces 22a, 22b be present in the annular groove 26 and the other of the Kunststoffflä chen 22b, 22a in the region of the hole 27.
- the door contact part 19 it is also possible to design the door contact part 19 as a one-piece metal part, so that a dedicated line 25 can be omitted or is formed by the metal part as such.
- the mating contact surfaces 24a or 24b correspond to the surface area of the door contact part 19 that is actually brought into contact with the contact surfaces 22a, 22b.
- the shape of the contact parts 19 and 20 can also be interchanged, i.e. the door contact part 19 has the annular groove 26 and the hole 27 and the door contact part 20 has the circular rib and the pin-shaped projection that can be inserted therein.
- the shape of the contact parts 19 and 20 is generally not limited to the annular groove-like shape shown, but can, for example, have simple flat contact surfaces, pin-like contacts, etc.
