Description

  The present invention includes a connecting device for releasably connecting a steam supplying device to a steam generating device in the steam supplying device, the connecting device being a steam for connecting to a corresponding connecting element of the steam generating device. A conduit connection element, two supply voltage contact elements for connection to a corresponding contact element of the steam generator, to which a supply voltage is applied, and a corresponding contact element of the steam generator A protective contact element for connection to a contact element connected to a protective earth and a corresponding contact element of a steam generator to which a safety ultra-low voltage is applied in between In the form of two ultra-low voltage contact elements for connection On.

  The invention also relates to a steam generator.

  The present invention further relates to a combined steam generation / steam supply device.

  A steam supply device of the aforementioned kind is described as a component part of a combined steam generation and steam supply device in EP 0809728 and is configured as a steam iron. The steam iron can be detachably connected to the correspondingly formed connecting device of the steam generator by the connecting device. The steam generator provides steam, which can be supplied to the steam iron via a steam conduit connection element, and the steam generator is electrically connected to provide a supply voltage and a safety very low voltage. Includes equipment. A supply voltage, for example a power supply voltage, in particular 230V or 110V, can be taken out by the supply voltage contact element. This makes it possible to supply the steam iron heater with the electrical energy used to heat the bottom plate. The heater is connected between supply voltage contact elements. For example, a safety ultra-low voltage of a level of several tens of volts can be taken out by an ultra-low voltage contact element, and a switching element operable by a user is connected between the ultra-low voltage contact elements. Actuating such a switching element will actuate a valve located in the steam generator, thereby selectively opening or closing the steam conduit. Steam can penetrate into the gap between the electrical contact elements due to leakage of the steam conduit connection element or even when the steam supply is separated from the steam generator. This results in increasing the electrical conductivity of the air in the gap. A current bridge is formed between the contact elements, and such a current bridge can cause a discharge. The discharge is typically performed via a supply voltage contact element. The connecting device and the correspondingly formed connecting device of the steam generator each include a protective contact element for safety reasons. Through this protective contact element, the discharge current can be dissipated substantially to the protective ground. However, it is also conceivable that the discharge current flows out through the ultra-low voltage contact element to the steam supply or steam generator and puts the user at risk.

  It is an object of the present invention to provide a steam supply device of the aforementioned kind in which the risk of damage to the steam supply device and the steam generator caused by the discharge and the associated danger to the user are reduced.

  The object is that according to the invention, for a typical steam supply device, the spacing between the supply voltage contact element and the protective contact element is greater than the spacing between the supply voltage contact element and the ultra-low voltage contact element. Achieved by being small.

  With such a configuration, the discharge as a result of the current bridge, which can be generated in particular due to the vapor surrounding the electrical contact element, causes the supply voltage contact element and the protective contact element as desired. Can actually increase the probability of being performed. In contrast, the probability of a discharge between the supply voltage contact element and the very low voltage contact element is only very low. The advantage of this is that the discharge current can be dissipated through a protective ground rather than through a very low voltage contact element. This reduces the risk of damage to the steam generator and to the steam supply. As a result, the danger to the user can be reduced.

  Advantageously, the plurality of supply voltage contact elements have the same spacing from the protective contact element. The discharge between each of the supply voltage contact elements and the protective contact element is therefore performed with the same probability. This is achieved, for example, by applying a power supply voltage to the supply voltage contact element (thus these are the neutral conductor and the phase conductor) and connecting the steam generator power plug to the power grid in two opposing directions. This is important when the polarity is reversed.

  The distance between the supply voltage contact elements is equal to the distance between each supply voltage contact element and the protective contact element, so that the supply voltage contact element and the protective contact element are at the apex of an equilateral triangle. It's okay. This enables a discharge between the supply voltage contact element and the protective contact element while at the same time achieving the compactest possible construction of the connecting device, and at the same time a discharge between the supply voltage contact elements. Try to avoid it as much as possible.

  Furthermore, the distance between one or both of the ultra-low voltage contact elements and the protective contact element may be greater than the distance between the supply voltage contact element and the protective contact element.

  Preferably, the spacing between the supply voltage contact element and the steam conduit connection element is greater than the spacing between the ultra-low voltage contact element and the protective contact element and the steam conduit connection element. As a result, the supply voltage contact element is arranged as far as possible from the steam conduit connection element. Thus, the probability that the leaked vapor will spread to the supply voltage contact element and cause a discharge is reduced.

  Advantageously, the protective contact element is arranged between the supply voltage contact element and the ultra-low voltage contact element. This makes it possible with a very high probability that both discharges originating from the supply voltage contact element and those originating from the very low voltage contact element can be dissipated to the protective ground via the protective contact element.

  The connection device separates the first connection region from which the steam conduit connection element is disposed, the second connection region in which the electrical contact element of the connection device is disposed, and the first connection region from the second connection region. Advantageously comprising at least one separating element. The separation element can suppress the spread of steam from the first connection region into the second connection region. This reduces the risk of a discharge being formed between the electrical contact elements of the connecting device.

  Preferably, the at least one separation element is a partition between the first connection region and the second connection region, and the partition at least partially surrounds the electrical contact element so that it is structurally simple. To achieve as effective a shielding action as possible between the connection areas.

  In order to ensure a particularly effective shielding action between the connection areas, it is advantageous if the partition completely surrounds the electrical contact element.

  The connecting device includes at least one alignment member for cooperating with a correspondingly formed alignment member of the steam generator. On the one hand, this means that the steam supply is correctly connected to the steam generator, and thus by forming a steam conduit and by properly linking the corresponding electrical contact elements. Guarantee. On the other hand, the provision of at least one alignment member makes it possible to “encode” the connecting device. Therefore, it can be ensured that the steam supply device can only be connected to a steam generator that is compatible with the steam supply device. The steam generator includes a corresponding alignment member and is suitable for providing the voltage or power required to operate the steam supply.

  The at least one alignment member is, for example, a protrusion or a receiving part for the protrusion, specifically a rib and a groove, respectively.

  Advantageously, this at least one alignment member is encompassed by or arranged on the separating element described above to achieve a simple structure of the connecting device.

  The connecting device includes an outer housing, the outer housing containing the steam conduit connecting element and also containing the inner housing containing the electrical contact element of the connecting device; A compact design and simple structure can be achieved. For example, an outer housing in the form of two halved shells may form a plug or socket for connection to a corresponding socket or corresponding plug of the steam generator, respectively. The contact element is housed in the inner housing. The inner housing is housed within the outer housing and likewise forms a plug or socket for plug connection into a correspondingly formed socket or correspondingly formed plug of the steam generator, respectively. This “plug-in-plug” design allows for a complete and structurally simple structure of the connecting device.

  The inner housing preferably forms at least one separating element as described above, which further preferably also includes at least one alignment member as described above.

  For the steam supply device according to the invention, the supply voltage contact elements may be short-circuited to each other so that only one circuit is closed by connecting the steam supply device with the steam generator. In this case, the supply voltage contact elements can have the same potential, i.e. the voltage between them does not drop.

  Usually, however, electrical energy is supplied to the steam supply via a supply voltage contact element to power the electrical load encompassed by the steam supply.

  The steam supply device includes an electrical load connected between the supply voltage contact elements, and this electrical load can convert the electrical energy supplied to the steam supply device into different energy forms. It is advantageous if possible. The electrical load includes, for example, a heating device for generating thermal energy.

  Specifically, the preferred embodiment of the last-mentioned steam supply device may comprise a steam iron having an electrical load in the form of a heating device for heating the bottom plate.

  With regard to the ultra-low voltage contact element, the ultra-low voltage contact element has the same potential, and the circuit for controlling the supply of steam, for example, is closed by connecting the steam supply to the steam generator. The ultra-low voltage contact element may also be shorted in the steam supply.

  Furthermore, the steam supply device advantageously includes a switching element connected between the ultra-low voltage contact elements and used to short-circuit the ultra-low voltage contact elements together. By means of a switching element, for example a push button, a short circuit between the ultra-low voltage contact elements can be selectively caused and removed again. This can be used, for example, to selectively open and close a valve located within the steam generator to open and close the steam conduit.

  Similarly, the steam supply device advantageously includes a regulating element connected between the ultra-low voltage contact elements and used to change the voltage difference that exists between the ultra-low voltage contact elements. . Using an adjustment element, such as a potentiometer, the user can dissipate electrical energy as needed by adjusting the voltage difference between the supply voltage contact elements. Changing the voltage difference is used in the steam generator, for example, to adjust the steam delivery.

  As mentioned above, the present invention also relates to a steam generator.

  A steam generator according to the present invention that achieves the above-described object includes a connecting device for separably connecting to one of the above-described steam supply devices, an electrical heating device for evaporating water, and steam. An electrical appliance for providing a supply voltage and a safety ultra-low voltage for the supply device, wherein the connection device of the steam generator comprises a steam conduit connection element for supplying evaporated water; Two supply voltage contact elements between which a supply voltage is applied, a protective contact element connected to a protective ground, and two supply voltage contact elements between which a safety extra low voltage is applied The distance between the supply voltage contact element and the protective contact element is the distance between the supply voltage contact element and the ultra-low voltage contact element. Smaller than the interval.

  The advantages mentioned in the context of the description of the steam supply device according to the invention can be achieved in particular with a steam generator combined with a steam supply device.

  The features of the above-mentioned advantageous embodiment of the steam supply device according to the invention, which are related to the configuration of the connection device of the steam supply device, preferably apply correspondingly to the connection device of the steam generator.

  It is therefore particularly advantageous if the supply voltage contact elements of the steam generator have the same spacing from the protective contact elements of the steam generator.

  The mutual spacing of the supply voltage contact elements is preferably equal to the distance between each supply voltage contact element and the protective contact element.

  Advantageously, the spacing between the supply voltage contact element and the steam conduit connection element is greater than the spacing between the ultra-low voltage contact element and the protective contact element of the steam generator and the steam conduit connection element.

  Advantageously, the protective contact element is arranged between the supply voltage contact element and the ultra-low voltage contact element.

  The connection device of the steam generator preferably also has a first connection region in which the steam conduit connection element is disposed, a second connection region in which the electrical contact element of the connection device is disposed, and a first connection region. At least one separation element separating the second connection region from the second connection region.

  The at least one separation element is a partition between the first connection region and the second connection region, advantageously the partition at least partially surrounds the electrical contact element, and the partition is electrically It is particularly preferred to completely enclose the contact element.

  The connection device of the steam generator can have at least one alignment member for cooperating with a correspondingly formed alignment member of the steam supply device. This alignment member is arranged, for example, on at least one separation element or is contained by said separation element.

  The steam generator connection device may also include an outer housing that houses the steam conduit connection element and also houses the inner housing that houses the electrical contact element of the connection device. Yes.

  The above-mentioned type of steam generator, together with at least one steam supply device of the above-mentioned type, can form a combined steam generation / steam supply device according to the present invention that achieves the above object in the same manner.

  The invention will be described in more detail by the following description of preferred embodiments of the invention in connection with the drawings.

FIG. 1 is a steam generation / steam supply device according to the present invention, and includes a steam generation device according to the present invention, a steam supply device according to the present invention in the form of a steam iron, and another steam supply device. It is a figure which shows the preferable embodiment of. FIG. 2A is a top view showing a connection tool of the steam generator of FIG. FIG. 2B is a schematic diagram illustrating electrical appliances of the steam generator of FIG. 1 and electrical contact elements of the connection fixture of FIG. 2A. FIG. 3A is a top view showing the steam iron connecting device of FIG. 1. FIG. 3B is a schematic diagram showing the electrical contact elements and other connecting portions of the steam iron of FIG. 4 is a cross-sectional view taken along line 4-4 of FIG. 3A.

  FIG. 1 shows a preferred embodiment of a combined steam generation / steam supply device 1 according to the present invention. The device 1 comprises a preferred embodiment of the steam generator according to the invention, which is shown below as a steam generator 10. The steam generator 10 includes a housing 12 with rollers. A known electrical heater (not shown) is housed in the housing 12 and water is contained in a water tank (known per se, not shown) or in a continuous water heater. Is used to heat. The water can be evaporated by heating and can be selectively discharged via the connection 14 of the device 1 to one of the two steam supply devices 16 or 18 of the device 1.

  The steam supply device 16 is a preferred embodiment of the steam supply device according to the present invention as part of the device 1, i.e. an embodiment in the form of a steam iron, which steam iron is shown below as an iron 20. The iron 20 includes a connection line 22, and a connection tool 24 is arranged in the form of a plug 26 at the end of the connection line. The plug 26 together with the connection device 28 of the steam generator 10 realized as a socket 30 forms a detachable connection 14.

  The steam supply device 18 is a floor nozzle 32 provided for floor cleaning, and has a connection line 34. At the end of the connecting line 34, a connecting device 36 in the form of a plug 38 is arranged. The plug 38 can also be detachably connected to the socket 30 to detachably connect the floor nozzle 32 to the steam generator 10.

  The steam generator 10 includes an electrical appliance 40 that is only schematically illustrated in FIG. 2B. The internal structure of the electrical appliance 40 in this case is that the electrical appliance 40 includes four electrodes 42, 44, 46 and 48 and a grounding pole 50, and the grounding pole is a power plug (not shown) of the steam generator 10. Only as long as it is electrically connected to the protective ground 52 via A detailed structure of the electrical appliance 40, which can also include the heating appliance described above for evaporating water, can be found, for example, in EP 0809728. In order to understand the invention, in this case it is sufficient to know that the supply voltage for the steam supply device 16 is applied between the poles 42 and 44. The level of the supply voltage is determined inter alia by the construction of the electrical appliance 40, and in the case of the steam generator known from EP 0809728, the supply voltage is a power supply voltage of the level of, for example, 230V or 110V. It's okay. The poles 42 and 44 are conductively connected to the electrical contacts F and G of the socket 30. These contacts F and G form the supply voltage contact elements F and G of the steam generator 10.

  The ground electrode 50 is electrically connected to the contact D of the socket 30. This contact D forms the protective contact element D of the steam generator.

  Further, a voltage, that is, a safety ultra-low voltage of a level of several tens of volts is applied between the poles 46 and 48. A safety ultra-low voltage is generated, for example, by changing the supply voltage applied to poles 42 and 44. This is also described in EP 0809728. The poles 46 and 48 are electrically connected to the contacts A and C of the socket 30. These contacts A and C form the ultra-low voltage contact elements A and C of the steam generator 10.

  In addition to A, C, D, F and G described above, socket 30 also includes contacts B, E and H. However, these contacts B, E and H are not assigned. Contacts A to H are female contact elements in the form of sockets. Of course, however, the contact can also be a male contact element in the form of a plug.

  Further, the socket 30 includes a steam conduit connection element 54, which is shown in the following as a steam nipple 56. Steam nipple 56 is shown only in FIG. 2A and not in FIG. 2B.

  Through the steam nipple 56, the steam provided by the steam generator 10 can be supplied to the steam supply devices 16 and 18. In the case of the iron 20, this is done by being able to connect a steam conduit connection element 54 ′ in the form of another steam nipple 56 ′ of the plug 26 to the steam nipple 56. Steam from the steam generator 10 can then be supplied to the actual iron 20 through steam nipples 56 and 56 ′ and the connection line 42.

  The plug 26 of the iron 20 also includes a plurality of electrical contacts A'-H '. These contacts are in this case formed as male pin contacts. Contacts A ′ and C ′ can cooperate with contacts A and C of socket 30. Contact D 'can cooperate with contact D of socket 30 and contacts F' and G 'can cooperate with contacts F and G of socket 30. The contacts B ', E' and H 'of the plug 26 are not assigned.

  Contacts F 'and G', which can be connected to contacts F and G, form the supply voltage contact element of the plug 26. They are connected to each other in the iron 20 by interconnecting with an electrical heater 58, between which there is a supply voltage, which is also present between the contacts F and G. Then, it is applied to the heating device 58. The heating device 58 enables the heating of the bottom plate 62 of the iron 20 as needed, and the heat output can be adjusted by the adjustment element 60.

  The contact D 'forms the protective contact element D' of the iron 20 and is connected to the protective ground 52 via the contact D. This is represented symbolically in FIG. 3B.

  Contacts A 'and C' form ultra-low voltage contact elements A 'and C' of plug 26. The same ultra-low voltage is applied between these ultra-low voltage contact elements A 'and C' as between contacts A and C of the socket 30. Furthermore, the contacts A 'and C' are electrically connected to each other in the iron 20, and a switching element 64 in the form of a push button 66 is also connected in the connection. When the push button 66 is actuated by the user, the contact elements A ′ and C ′ are short-circuited and the valve of the electrical appliance 40 connected to the poles 46 and 48, in particular a magnet valve (not shown). By releasing the steam conduit in the steam generator 10, the steam can flow through the connecting conduit 22 to the iron 20. The strength of the steam flow can be adjusted by a control element 67 on the steam generator.

  As is apparent from FIGS. 2A and 3A, the socket 30 and plug 26 include outer housings 68 and 68 'consisting of half shells 70 and 72, and 70' and 72 ', respectively, in a compact design. The outer housings 68 and 68 'contain on the one hand steam nipples 56 and 56' and on the other hand inner housings 74 and 74 '. The inner housing 74 is an electrical socket 76 containing the contacts A to H of the socket 30, and the inner housing 74 ′ correspondingly is a plug containing the contacts A ′ to H ′ of the plug 26. 78.

  As is further apparent from FIGS. 2A and 3A, the contacts A to H and the contacts A 'to H' are respectively disposed on the socket 30 and the plug 26 as follows.

  The contacts A to C and A 'to C' are arranged in a first contact row, respectively. The contacts D and E and the contacts D 'and E' are arranged in a second contact row parallel to the first contact row. The contacts F to H and the contacts F 'to H' are arranged in a third contact row extending in parallel with the first and second contact rows, respectively. The first contact rows (A to C and A 'to C', respectively) have the smallest distance from the steam nipples 56 and 56 '. The third contact rows (FH and F ′ to H ′, respectively) have the largest distance from the steam nipples 56, 56 ′, and the second contact rows (D and E, and D ′ and E ′, respectively) Arranged between the first and third contact rows.

  Accordingly, among the assigned contacts of the socket 30 and the plug 26, the contacts F and G to which the supply voltage is applied, and F 'and G' have the largest distances from the steam nipples 56 and 56 ', respectively. Contacts D and D ′ connected to the protective ground are arranged between the supply voltage contact elements F and G and F ′ and G ′ and the ultra-low voltage contact elements A and C and A ′ and C ′. ing. As a result, the spacing of the supply voltage contact elements F and G and F ′ and G ′ with the protective contact elements D and D ′ is respectively separated from the ultra-low voltage contact elements A and C and A ′ and C ′ Less than the interval.

  Contacts D, F and G on the one hand and D ', F' and G 'on the other hand form vertices of equilateral triangles, respectively.

  The above-described spatial arrangement of the contacts A to H and A 'to H' has the following advantages from the viewpoint of safety. That is, the protective contacts D and D ′ connected to the protective ground are arranged between the contacts F and G and F ′ and G ′, respectively, on one side to which the supply voltage is applied, and Since the other side to which the low voltage is applied is arranged between the contacts A and C and A ′ and C ′, the contacts F and G to which the supply voltage is applied, and F ′ and G ′, respectively. Can be dissipated to the protective ground 52 via contacts D and D ′ with a very high probability. Correspondingly, the discharges originating from the contacts A and C and A ′ and C ′, respectively, are dissipated to the protective earth 52 via the contacts D and D ′ in the intended manner and with a very high probability. Can do.

  In contrast, the probability of a discharge occurring between contacts F and G and F ′ and G ′ to which a supply voltage is applied, and between contacts A and C and A ′ and C ′ to which an ultra-low voltage is applied, respectively. Very low. As a result, the probability of damaging the iron 20 and the steam generator 10 when a discharge occurs is significantly reduced. Specifically, the probability that the discharge current flows out to the electrical appliance 40 via the contacts A and C is very low.

  For example, if the sealing action between the steam nipples 56 and 56 'is incomplete, for example if the steam escapes from the steam conduit in an undesired manner, a discharge may occur between the contacts. Vapors in the regions of contact elements A-H and A'-H 'can increase the electrical conductivity of the air, thus forming a current bridge between the contacts, which can cause a discharge. When the plug 26 is separated from the socket 30, i.e. when steam escapes from the iron and / or steam generator through steam nipples 56 'and 56, respectively, between the contacts AH and A'H'. Steam may penetrate.

  In order to generally minimize the contact of the contacts F and G and F ′ and G ′, which are subjected to a high level of supply voltage, with the steam, these contacts are assigned to the remainder of the socket 30 and the plug 26 as described above. Are far away from the steam nipples 56 and 56 ', respectively.

  Furthermore, the contacts A to H and A 'to H' are protected against steam by separating elements 80 and 80 ', respectively. Separating elements 80 and 80 'are formed by outer walls 82 and 82' of socket 76 and plug 78, respectively. The walls 82 and 82 'are closed around and completely surround the contacts A to H and A' to H ', respectively, in the circumferential direction relative to the connecting direction of the iron 20 and the steam generator 10. Accordingly, the walls 82 and 82 'are respectively connected to the first connection regions 84 and 84' of the socket 30 and the plug 26 where the steam nipples 56 and 56 'are disposed, and the contacts A to H and A' to H ', respectively. It isolate | separates from the arrange | positioned 2nd connection area | region 86,86 '. Such separation inhibits vapor from penetrating into the regions between the contacts A-H and A'-H ', respectively, thereby reducing the risk of electrical discharge.

  Walls 82 and 82 'further include alignment members 88 and 88', respectively, in the form of ribs 90 and channel-shaped recesses 92. Ribs 90 and channel-shaped recesses 92 can cooperate with each other for their mutual alignment when connecting plug 28 to socket 30.

  In addition, the rib 90 and the recess 92 allow a kind of “encoding” of the socket 30 and the plug 26, respectively. In fact, in this case, the plug 26 can be connected to the socket 30. This is because the rig 90 and the recess 92 can be fitted together based on their spatial arrangement. However, the ribs may be located at different locations on the wall 82 in different unillustrated embodiments of the steam generator 10. This prevents the iron 20 from being connected to such a steam generator by a plug 26. This is because the wall 82 'does not include a groove-shaped recess at the required position. Such encoding can only be connected to the steam generator 10 that can provide the power required to operate the iron 20 as intended, and of course, the contacts A-H can be connected to the iron 20. It is desirable to ensure that it can also be connected to a steam generator such as that assigned to correspond to the contacts A ′ to H ′.
