Description

[0001] Household appliance and drawer guide for a household appliance

[0002] The invention relates to a pull-out guide for a household appliance with a microwave cooking function, comprising a body rail and at least one guide rail movable relative thereto for depositing a food carrier. The body rail and / or the guide rail have a U-shaped profile with a base and two legs. The invention further relates to a household appliance with a microwave cooking function having such a pull-out guide.

[0003] In various types of household appliances, pull-out guides have become established, onto which removable supports, for example food carriers such as trays or racks, can be placed. These can be easily pushed into or pulled out of the household appliance using the pull-out guide and removed more easily.

[0004] Drawer runners with a U-shaped profile for the cabinet rail and / or track have proven advantageous in that they allow for a compact design and are well protected from dirt penetration by the U-shaped profile. The U-shaped profile is typically punched and bent from sheet metal.

[0005] To prevent sharp edges at the front end of the guide rail from posing a risk of injury, and also for aesthetic reasons, it is common practice to close off the front end of the U-shaped profile of the guide rail. This can be done using a welded-on plate over the entire surface or using an inserted plug. The plate or part of the plug often protrudes upwards above the support surface of the guide rail to form a support for a food carrier placed on it and thus prevent the food carrier from slipping off the guide rail when pulled out of a cooking chamber. The rear end of a U-shaped body rail usually remains open.

[0006] When using a metal guide or body rail with a U-shaped profile in a microwave oven, it has been shown that if the front and / or rear ends of the rail are open, the temperature of metallic elements located within the volume enclosed by the U-shaped profile increases relative to the surrounding area, thus reducing the efficiency of the microwave oven. A similar behavior is observed when the profile rails are sealed with a plug made of an electrically insulating material.

[0007] It is an object of the present invention to provide a pull-out guide for a household appliance with a microwave cooking function and a household appliance equipped therewith, in which an increase in temperature of elements in the volume encompassed by the respective rail is prevented or at least reduced as far as possible, even if the end of a U-shaped guide rail and / or carcass rail is open or closed by an electrically insulating material.

[0008] This object is achieved by a drawer slide or a household appliance with a microwave cooking function having the features of the respective independent claim. Advantageous embodiments and further developments are the subject of the dependent claims.

[0009] A pull-out guide according to the invention of the type mentioned at the outset is characterized in that in an end region of the body rail and / or the running rail, the legs are electrically connected to one another by a contact element, wherein the contact element is arranged at a distance from the base.

[0010] It has been shown that microwaves no longer penetrate the front opening of the profile of a runner or cabinet rail when the free ends of the legs are electrically connected to one another. This connection creates a ring-shaped, closed, conductive structure consisting of the base of the rail, the legs and the contact element, which reflects microwaves. The remaining open area - i.e. the opening of the ring-shaped structure - is small enough for the usual height and width of the rails of a pull-out guide, which are each in the range of a few millimeters to around one centimeter, to allow microwaves to penetrate deeper into the volume enclosed by the respective rail. Unnecessary and undesirable heating of, for example, the rolling element cage of the pull-out guide is reduced or avoided, with the arrangement of a contact element in the area of ​​one of the two front sides already bringing about a significant reduction in the temperature increase.A full-surface shielding of the entire opening area is not required, which on the one hand saves material and on the other hand makes it possible to cover the front side of the rail - except for the area of ​​the contact element - in another way, e.g. with an insulating plug.

[0011] It should be noted that the "U-shape" of the body or track rail, as defined in the application, encompasses any shape in which two lateral legs are arranged at a distance from each other on a base. The two legs can be of equal or different lengths and can be at the same angle, in particular at right angles to the base, or at different angles. Furthermore, each of the legs can be straight, angled, or curved, particularly in the area of ​​its free end. A trapezoidal shape or a C-shape therefore also falls under the term "U-shaped" in the context of the application.

[0012] In an advantageous design of the drawer slide, the cabinet rail and / or the guide rail are made of metal. The contact element is also advantageously made of a metal sheet or wire. Due to its high electrical conductivity, this provides good microwave shielding.

[0013] In a further advantageous embodiment of the drawer slide, the contact element is U-shaped and has a base and two lateral legs. A contact element shaped in this way can be easily inserted into the cabinet or guide rail, with the contact element's legs preferably contacting the legs of the cabinet rail or guide rail on the inside, and the bases facing each other.

[0014] In one embodiment, recesses can be arranged in the legs of the cabinet rail and / or the guide rail, into which the contact element engages with a locking action. For this purpose, the contact element preferably has outwardly extending contact tabs at the free ends of its legs, with which it engages in the recesses. The U-shaped geometry of the contact element creates a spring effect, which, on the one hand, ensures the mechanical locking of the contact element and, on the other hand, ensures good electrical contact.

[0015] Alternatively or additionally, the contact element can be welded to the legs of the cabinet rail and / or the guide rail. A U-shaped contact element is also advantageous for this, with the legs of the contact element lying as flat as possible against the legs of the rail. Welding can then preferably be performed using a spot welding process.

[0016] In a further advantageous embodiment of the pull-out guide, a plug is inserted into a front end of the guide rail and / or a rear end of the cabinet rail, with the contact element arranged on or in the plug. The plug covers the front of the cabinet and / or guide rails, which protects against injuries from otherwise potentially sharp edges of the rail. Furthermore, the plug can be made of an electrically insulating material, thereby providing effective protection against arcing from the guide rail to the front of the microwave oven. Further advantages arise if the material of the plug is also thermally insulating and / or shock-absorbing. In this embodiment, the plug is also used to accommodate the contact element. By inserting the plug into the rail, the legs of the U-shaped profile are also contacted in a single step.

[0017] In one embodiment, the plug has an insert body that is clamped and / or latched to the guide rail and / or the body rail, with the contact element being arranged on and / or at least partially within the insert body. Preferably, at least one recess is provided on the insert body, which at least partially accommodates the contact element in order to secure it to the plug and to insert the unit consisting of the plug and contact element into the rail.

[0018] The following electrically insulating materials can be used for the plug: ceramics, high-temperature-resistant thermoplastics, in particular from the polyether ketone family (e.g. polyether ether ketone - PEEK) and / or elastomers, in particular from the polysiloxane or thermoset family.

[0019] A household appliance with a microwave cooking function according to the invention is characterized by having at least one such pull-out guide. This results in the advantages mentioned in connection with the pull-out guide.

[0039] In all figures, identical reference symbols identify identical or identically functioning elements. For reasons of clarity, not all elements are provided with reference symbols in all figures. Where relative terms such as "left" or "right" are used in the description, these refer to the figures described. Only the terms "front", "rear", "top" and "bottom" refer to the natural orientation of the pull-out rail during operation, with a food carrier resting on top of the pull-out rail and the front end of the pull-out rail pointing towards a user who is standing in front of the household appliance in which the pull-out guide is used.

[0040] Figures 1 a, b show a first embodiment of a pull-out guide according to the application.

[0041] The pull-out guide has a stationary cabinet rail 1, which can be secured in or to a household appliance using mounting elements not shown here, such as mounting clamps. The pull-out guide is suitable for a microwave oven. The pull-out guide can be mounted, for example, on a side rail, which is typically located in the cooking chamber of the appliance.

[0042] A food carrier, such as a baking tray or a rack, can be placed on top and moved into or out of the cooking chamber using the pull-out guide.

[0043] The drawer guide comprises a guide rail 2, which is mounted so that it can move relative to the cabinet rail 1. In the example shown, the cabinet rail 1, as well as the guide rail 2 and the mounting elements, are made of metal, e.g., from appropriately punched and bent sheet metal.

[0044] The guide rail 2 is U-shaped and has an upwardly facing base 21 and two lateral legs 22. It has a front end section 23 (in the extension direction) and an opposite rear end section 24. A stop 4, in the form of a cylindrical bolt, is attached to the base 21 of the guide rail 2 in the rear end section 24. The stop 4 prevents a food support resting thereon from slipping backward. Additionally, a damping cap can be attached to the bolt, which dampens the impact of an edge of the food support on the bolt.

[0045] Between the cabinet rail 1 and the guide rail 2 is an arrangement of rolling elements (not visible here), which allows the guide rail 2 to move easily relative to the cabinet rail 1. Additional components, such as additional guide rails or center rails, can also be arranged between the cabinet rail 1 and the guide rail 2 to enable an extension of the drawer.

[0046] In the front end section 23 of the guide rail 2, two recesses 25 are formed in the material of the guide rail 2. A contact element 3 is inserted into these recesses 25. Figure 1a shows the contact element 3 in a disassembled state before insertion; Figure 1b then shows the drawer guide with the contact element 3 inserted.

[0047] The contact element 3 is made of an electrically conductive sheet metal and connects the legs 22 of the U-shaped guide rail 2 in its front end section 23 in an electrically conductive manner.

[0048] This is based on the knowledge that microwaves can no longer penetrate the U-shaped guide rail 2 from the front if the free ends of the legs 22 are electrically connected to one another. The connection creates a ring-shaped, closed conductive structure consisting of the base 21, legs 22 and contact element 3, which reflects microwaves. The remaining open area - i.e. the opening of the ring-shaped structure - is, with the usual height and width of the guide rail 2, which are in the range of a few millimeters up to about one centimeter, small enough for microwaves to penetrate deeper into the volume enclosed by the guide rail 2. Unnecessary and undesired heating of, for example, the rolling element cage of the pull-out guide is avoided or is significantly reduced. This effect is already noticeable even if only one of the two end faces is provided with a contact element of the type mentioned.

[0049] A contact that is positioned as close as possible to the edge both in the extension direction and in the direction of the free ends of the legs 22 of the U-shaped guide rail 2 has proven to be particularly effective.

[0050] Figures 2a-c show a further embodiment of a pull-out guide according to the application. Unlike the first embodiment, a so-called full extension is shown, wherein the pull-out guide has a center rail 5 in addition to the cabinet rail 1 and running rail 2. The structure of the running rail 2 in this second embodiment is fundamentally comparable to that of the first embodiment. In this case, the cabinet rail 1 is also U-shaped and has a base 11 and lateral legs 12. It has a front end section 13 and a rear end section 14. Analogous to the recesses 25 in the front end section 23 of the running rail 2, recesses 15 are introduced into the legs 12 in the rear end section 14 of the cabinet rail 1.

[0051] In this embodiment, a contact element 3 is inserted into the guide rail 2 and into the cabinet rail 1, respectively, in the corresponding recesses 25 and 15, respectively. This prevents microwaves from penetrating not only from the front into the internal volume enclosed by the guide rail 2, but also from the rear into the internal volume enclosed by the cabinet rail 1. Figure 2a shows the contact elements 3 in a disassembled state, separately, prior to insertion; Figures 2b and c then show the drawer guide with inserted contact elements 3 in two different extension positions.

[0052] Figure 3 shows the contact element 3 of the first two embodiments of the drawer slides in an enlarged, three-dimensional view. As previously mentioned, it is made of a conductive sheet material, preferably stainless steel, but also aluminum, copper, bronze, or other metal alloys.

[0053] In this example, the contact element 3 is bent into a U-shape with a base 31 and legs 32. The free ends of the legs 32 are flared outward, forming locking tabs 33. When inserted into the cabinet rail 1 or the guide rail 2, the locking tabs 33 lock into the corresponding recesses 15 and 25, respectively. This ensures a mechanically secure fit and, on the other hand, good electrical contact with low contact resistance.

[0054] In Figures 4a and b, a front part of the guide rail 2 is again enlarged and shown as viewed obliquely from below into the U-shaped profile. In Figure 4a, the contact element 3 is shown separately before insertion; in Figure 4b, it is inserted into the guide rail 2. Figures 5a-c, 6 and 7a and b, and Figures 8a-c, 9 and 10a and b, respectively, show a third and a fourth embodiment of a drawer guide according to the application, each in the same manner as in Figures 2a-c, 3 and 4a and b.

[0055] The basic structure in both cases corresponds to that of the second embodiment. A contact element 3 is also arranged in the front end section 23 of the guide rail 2 and a contact element 3 is arranged in the rear end section 14 of the cabinet rail 1.

[0056] Unlike the first two embodiments, the contact elements 3 are not mounted in the rails 1, 2 in a snap-in manner, but are welded on. Preferably, a contact spot welding method is used, as indicated particularly in Figures 6 and 9 by the intended position of a welding point 34.

[0057] The contact element 3 of the third embodiment of Figures 5a-c, 6 and 7a, b is, except for the locking tabs 33, comparable to that of the first two embodiments, a U-shaped bent sheet metal strip.

[0058] The contact element 3 of the fourth embodiment shown in Figures 8a-c, 9, and 10a, b, on the other hand, is a U-shaped wire bracket with legs 32 that have flats at their free ends. These flats form contact surfaces 35 with which the contact element 3 rests against the legs 12, 22 of the cabinet rail 1 or the guide rail 2. The contact surfaces 35 facilitate the welding process, and the intended position of the respective welding point 34 lies accordingly on the contact surface 35.

[0059] Figures 11a to 16c show three further embodiments of drawer guides, the basic structure of which corresponds to the drawer guide of the first embodiment and comprises a cabinet rail 1 and a U-shaped guide rail 2. Only a front section of each drawer guide is shown.

[0060] In all three embodiments, a plug 6 is inserted into the U-shaped profile of the guide rail 2 from the front. The plug 6 has an insert body 61 that is inserted into the profile of the guide rail 2. After the insert body 61 has been inserted, the plug 6 rests against the front end of the guide rail 2 with a contact element 62 that projects laterally and, in particular, upwardly beyond the insert body 61. The contact element 62 prevents a food carrier placed on it from slipping forward off the guide rail 2.

[0061] In contrast to the guide rail 2, which is made of metal, the plug 6 and in particular the contact element 62 are preferably made of an electrically insulating material, for example the plastic PEEK (polyetheretherketone). As a result, the contact element 62 of the plug 6 separates the metal of the guide rail 2 from a door, flap, or other front of the microwave cooking appliance. This prevents an otherwise possible arcing between the front end of the guide rail 2 and the front. Microwave cooking appliances often use a door or flap with a front pane provided with conductive elements, for example, a conductive coating or wires in the glass. The material of the contact element 62 or the plug 6 can also be shock-absorbing and / or thermally insulating, thus protecting the door or flap mechanically and against local thermal stress.

[0062] In the illustrated embodiments, the plug 6 is formed in one piece, for example, from plastic, e.g., the aforementioned PEEK, using an injection molding process. Alternatively, multi-part designs of the plug 6 are also possible.

[0063] In the front area of ​​the guide rail 2, two recesses are provided in the base 21 of the guide rail 2, into which, for example, locking elements of the insertion body 61 engage, so that the plug 6 is secured to the guide rail 6 after insertion. However, it is also possible to fasten the inserted plug 6 to the guide rail 2 by countersinking a web remaining between the two recesses.

[0064] According to the application, the three embodiments of Figures 11a to 16c also include a contact element 3 that electrically connects the legs 22 of the guide rail 2 in the front end section 23, spaced from the base 21. The contact element 3 is arranged in or on the plug 6. Figures 11ac and 12a, b show a first embodiment of such a pull-out rail, in which the plug 6 carries the contact element 3.

[0065] Figures 11 a and b each show a section of the cabinet rail 1 and the guide rail 2, as well as the plug 6 before insertion into the front end of the guide rail 2. Recesses 611 are formed laterally and from below in the insertion body 61 of the plug 6, into which the contact element 3, shown separately in Figure 11 a, is inserted. In this embodiment, the contact element 3 is a U-shaped wire section.

[0066] Figures 11b and 12a show the contact element 3 inserted into the insert body 61 from two different viewing directions. Finally, in Figures 11c and 12b, the insert body 61 is inserted into the guide rail 2. It can be seen that the contact element 3 connects the legs 22 of the U-shaped guide rail 2 in the region of the front end section 23. In this end region, the profile of the guide rail 2 is thus again electrically closed in a ring shape, thereby forming effective shielding against microwaves.

[0067] Figures 13a, b and 14ac show a second embodiment of a drawer guide with plug 6 and contact element 3. The representation in Figures 13a, b corresponds to that in Figures 11b, c. In Figures 14a, b, the plug 6 is shown separately in a spatial representation before the contact element 3 is mounted and with the contact element 3 mounted. Figure 14c shows a sectional view through the guide rail 2 with the plug 6 inserted.

[0068] In contrast to the previously described embodiment of Figures 11a to 12b, the contact element 3 is a U-shaped bent sheet metal, not a wire section. Accordingly, the recesses 611 in the insert body 61 are wider. For better retention of the contact element 3 on the insert body 61, inwardly directed locking tabs 33 are formed on the legs 32, by means of which the contact element 3 is fixed in the recesses 611. In principle, a similar effect is achieved as in the previously described embodiment, whereby the greater width of the sheet metal compared to the wire section leads to more secure contact between the contact element 3 and the legs 22 of the guide rail 2. Depending on the length of the individual legs 22 of the U-shaped guide rail 2, the contact element 3 can deviate from a symmetrical U-shape, as shown in Figure 14c, in order to connect the end sections 25 of the legs via the shortest route.

[0069] Finally, Figures 15a to 16c show a third embodiment of a pull-out guide with plug 6 and contact element 3 in a manner comparable to Figures 13a to 14c.

[0070] Here, comparable to the previous embodiment, a U-shaped sheet metal element is used as the contact element 3. In contrast to the previous embodiment, the legs 32 of the U-shaped contact element 3 are oriented in the extension direction and not perpendicular to it. The recesses 611 on the insert body 61 are also aligned accordingly.

[0071] The advantage here is that even greater clamping forces (which lead to better contact between the contact element 3 and the guide rail 2) can be applied without the risk of the contact element 3 being pushed out of the recesses 611 when inserted into the guide rail 2. To achieve particularly good electrical contact, in this embodiment the contact element 3 is additionally provided with an angled contact tab 36 on each of its two free outward ends. The contact tabs 36 represent the main contact points with the guide rail 2, which are preferably located in the front area of ​​the end section 23.A stop tab 612 integrated in the rear area of ​​the plug 6 prevents, on the one hand, the pre-assembled contact element 3 from falling out of the recess 611 during assembly and, on the other hand, prevents other guide elements, such as the body rail 1 or the center rail 5, from coming into contact with the contact element 3.

[0072] The contact elements 3 shown in the embodiments of Figures 11a - 16c can also be fixed to the plug 6 in a different way, such as by material, form and / or force fit, or can already be manufactured in a common manufacturing process, e.g. as an insert part or in 2-component injection molding.

[0073] The contact elements 3 described in the exemplary embodiments do not necessarily have to be designed identically for the cabinet rail 1 and the guide rail 2 of a drawer slide, nor do they have to be attached using the same method; they can also be combined with each other. Thus, by selecting the right contact elements 3, heat development in the drawer slide can be optimized, or the additional process step can be adapted to the manufacturing process of the drawer slide.
