Description

[0001] The present invention relates to a household appliance housing and a household appliance.

[0002] Domestic technical equipment typically features a housing and multiple penetrations for electrical cables and hydraulic feedthroughs.

[0003] The connection between a wall feedthrough and the housing should be tight and easy to install.

[0004] It is therefore an object of the present invention to provide a household appliance housing with a wall feedthrough which is easier to install.

[0005] This problem is solved by a household appliance housing according to claim 1.

[0006] The building services appliance housing has a wall and at least one recess for the cable entry, as well as a wall penetration. The wall penetration has retaining tabs that can be inserted into a correspondingly shaped recess in or on the wall. The wall penetration is then rotated to lock the retaining tabs in or on the wall. This essentially creates a bayonet-style connection.

[0007] The bushing is easy to replace and allows for tool-free locking. In particular, a reduction in the bushing's cross-section can be avoided. The bushing is therefore suitable for fluids and gases. Advantageously, the bushing consists of only one part, which can be placed in a recess in the wall.

[0008] The wall feedthrough has a first and second end, each with a first and second section, and a third section between the first and second sections. The third section can be designed as a flange. Retaining wings are provided at one end of the flange. Mounting wings or handles can optionally be provided at the other end of the flange. The mounting wings or handles allow the installer to rotate the wall feedthrough after inserting it into the recess. Optionally, the mounting wings / handles can also serve as an indicator of successful locking. For example, the retaining wings can be in a specific position to indicate that locking has occurred.

[0009] Optionally, the first section has a first inner diameter and the second section has a second inner diameter, the second inner diameter being smaller than the first inner diameter.

[0010] The recess in the wall has a first recess section and a second recess section. The first recess section is located centrally, while the second recess sections extend radially. The second recess sections are adapted to the shape and geometry of the retaining wings, allowing the first section to be inserted into the recess and the retaining wings to be guided through the wall by the second sections. The opening can then be rotated to lock the retaining wings against the wall.

[0011] Optionally, lugs can be provided in or on the wall. These lugs can be positioned, in particular, between two adjacent secondary recess sections. The lugs serve to engage with the retaining wings to prevent the wall penetration from rotating. Optionally, the wall can be made of sheet metal.

[0012] Optionally, the wall feedthrough is made of plastic. In particular, an injection molding process can be used, allowing the feedthrough to be manufactured in one piece.

[0013] The housing wall can have a thickness of 0.5 mm to 2.5 mm. Alternatively, wall thicknesses of ≥ 10 mm are also possible.

[0014] Further embodiments of the invention are the subject of the dependent claims.

[0015] The advantages and embodiments of the invention are explained in more detail below with reference to the drawing. Fig. Figure 1 shows a schematic representation of a procedure, Fig. 2A each show a wall feedthrough in one operating position and 2B each show an operating position, Fig. Figure 3 shows a schematic sectional view of a wall penetration, Fig. Figure 4 shows a schematic view of a wall penetration, Fig. Figure 5 shows a section of the wall penetration of Fig. 4, Fig. Figure 6 shows a schematic representation of a wall of a housing, Fig. 7A shows a top view of a wall penetration, Fig. 7B shows another top view of a wall penetration, Fig. Figure 8 shows a schematic side view of the wall penetration, and Fig. Figure 9 shows a sectional view of a wall penetration.

[0016] Fig. Figure 1 shows a schematic representation of a feedthrough for a household appliance. Fig. Figure 1 shows a wall 200 with a recess (pass-through recess) 210 and a wall penetration 300. The wall penetration 300 has a first and second end 310, 320 with a first section 312 and a second section 324. Furthermore, a third section 330 is provided between the first and second sections 312, 324. The third section 330 can be a flange 331. Two mounting wings 333 can be provided on one side of the flange 331. The second end 320 of the penetration 300 is inserted into the recess until the flange 331 rests on the wall 200. The wall penetration 300 is then rotated and locked, for example, by means of the mounting wings 333. At least one retaining wing 332 is provided on the side of the flange 331 opposite the mounting wing 333.

[0017] The recess 210 has a first and second recess section 211, 212. The first recess sections 211 extend radially to the second recess section 212. The first recess sections 211 are adapted to the shape of the retaining wings 332, so that the retaining wings 332 can be inserted into the first recess sections 211. Subsequently, the feedthrough 300 can be rotated to lock it in place.

[0018] In Fig. Figure 1 shows the first side of wall 200.

[0019] Fig. 2A and Fig. Figure 2B each shows a wall penetration in an operating position. Fig. 2A is the second end 320 of the passage 300 with the retaining wings 332 inserted into the recess 210 with the first recess sections 211 (wing recess). Fig. Figure 2A shows the implementation in a first operating position, namely for inserting the feedthrough through the recess. Fig. Figure 2B shows the feedthrough in a second operating position, in which the feedthrough is rotated and the retaining wings 332 engage in a section between the first recess sections 211. In this position, the retaining wings 332 come into contact with the lugs 220. This allows for locking or fastening.

[0020] Fig. Figure 3 shows a schematic sectional view of a wall penetration. Fig. Figure 3 shows the bushing in an installed state. In particular, the wall 200 with its first and second sides 201, 202, as well as the inserted bushing 300, are shown. The flange 331 rests against the first side 201 of the wall 200, and the retaining wings 332 are in contact with the lugs 220 on the second side 202 of the wall 200. Thus, the bushing 300 is fixed to the wall 200.

[0021] The locking of the feedthrough can be achieved, in particular without tools, simply by inserting the second end 320 of the feedthrough into the recess 220 and by rotating the feedthrough 300.

[0022] Fig. Figure 4 shows a schematic view of a wall penetration. Fig. Figure 4 shows a view of the second side 202 of the wall 200. Here, the feedthrough 300 has been inserted into the cutout 210 and rotated for locking. Thus, the retaining wings 332 are located on the second side 202 of the wall 200.

[0023] Fig. Figure 5 shows a section of the wall penetration of Fig. 4. In Fig. Figure 5 shows the implementation in a second operating position, wherein a holding wing 332 is in contact with one of the noses 320.

[0024] Fig. Figure 6 shows a schematic representation of a housing wall. The wall 200 has a recess 210 with a first and second recess section 211, 212. The second recess section 212 is arranged centrally, and the first recess sections 211 extend radially. Furthermore, for example, four lugs 320 are arranged between adjacent first recess sections 211.

[0025] The first recess sections 211 are adapted to the design of the retaining wings 332, so that the retaining wings 332 can be inserted through the first recess sections 211.

[0026] Fig. Figure 7A shows a top view of a wall penetration. Fig. Figure 7B shows another top view of a wall penetration. Fig. Figure 8 shows a schematic side view of the wall penetration. Fig. Figure 9 shows a sectional view of a wall penetration.

[0027] The bushing 300 has a first end 310 with a first bead 311, a first section 312, and a first inner diameter 313. The bushing 300 further has a second end 320 with a second bead 321, a radial O-ring recess 322 (for receiving an O-ring seal), a third bead 323, a second section 324, and a second inner diameter 325. A third section 330 is provided between the first and second sections 312 and 324. The third section 330 has a flange 331. Retaining wings 332 are provided on one side of the flange 331, and mounting wings 333 are provided on the other side of the flange 331. The retaining wings 332 have a wing section 332a, which is spaced 332b away from the flange 331.

[0028] The design of the retaining wings 332 allows the feedthrough 300 to be locked onto the sheet metal regardless of the sheet metal wall thickness.

[0029] To simplify assembly, mounting wings 333 can be provided at one end of the flange 331.

[0030] Optionally, axial preload can be applied to the wall 200.

[0031] The design of the recess and the design of the feedthrough 300 enable automatic centering during radial rotation. Furthermore, a wall thickness-independent locking mechanism can be achieved.

[0032] The 220 noses are advantageous because they allow for a locking mechanism. In particular, an audible click provides confirmation when the nose engages.

[0033] Optionally, a seal can be provided for the wall 200 to improve the sealing properties.

[0034] An O-ring seal can be provided in the radial O-ring recess 322.

[0035] To mount the bushing 300, a second end 320 of the bushing 300 is placed in a recess in the wall 200 until the flange 331 rests against the wall 200. The bushing is then rotated to allow it to lock into place.

[0036] Optionally, quick, easy and cost-effective assembly, in particular tool-free assembly without additional connecting parts, can be achieved.

[0037] The wall thickness of wall 200 can be between 0.5 mm and 2.5 mm or alternatively ≥ 10 mm.
