Charging port for drum washing machines front loading

 

The charging port is formed a circular area 5 constituting the bottom, and section 4 constituting the side wall. Section 5 constituting the bottom, consists of the sight glass 10 having an inner surface 12 and the edge region 14. Tapering in the direction constituting the bottom section 5 constituting the side wall section 4 of the bowl consists of a rigid synthetic material. Sight glass 10 throughout the length of the edge section 14 constituting the bottom section 5, curved in the direction of section 4, which constitutes the side wall, so that the edge region 14 of section 5, constituting the bottom, forms a rounded glass ledge 16. On the outer edge of the glass ledge 16 sight glass 10 includes slanted relative to the inner surface 12 of section 5, constituting the bottom, the annular coupling section 6, which is its upper end 18 in firm engagement with the inner end 20 of section 4, which constitutes the side wall. The technical result is to create a boot hatch is relatively easy and simple to use, providing reliable sealing of the housing. 5 C.p. f-crystals, 3 ill.

Nastoeashemu closed inside the washing machine bowl with a round section constituting the bottom, and the area constituting the side wall, while the section constituting the bottom, formed a sight glass comprising essentially flat inner surface, and the boundary region, and tapering in the direction of the section constituting the bottom of the bowl, the area constituting the side wall is formed from synthetic material.

The washing machines front loading on the front side is equipped with the charging port, made in most cases of circular and includes a sight glass in the bottom of the loading door for drum washing machines front loading of a transparent material, allowing the user to look inside the washing machine. Open the boot hatch things can be loaded directly into the drum and removed from it. Usually for drum washing machines front loading applied loading hatches, having a bowl shape, closed inside a washing machine. Thus, the space between the side surface of the housing and the drum linen filled the bottom of the loading door so that eliminates the dead space between the housing of the washing machine and the rotating drum for the present time in most cases of the Cup-shaped element made of glass or transparent synthetic material. As the charging port limits dryer for linen directly from the opening, it is important between the rotating drum and the stationary components of the machine to create the appropriate seal.

Like the charging port is known, for example, from the description of the utility model DE 9014622 U1. This publication describes a transparent Cup-shaped element essentially hemispherical shape and covering the frame element, which is located on the edge of the outer perimeter of the Cup-shaped element. Preferably Cup-shaped element made of glass, but may also consist of a transparent synthetic material.

The disadvantage of charging port on DE 9014622 U1 in the application of transparent synthetic material is that it provides optimal visibility in the dryer for linen as the material degrades in particular due to chemical action and abrasion from rotating linen after prolonged use. Use the same glass for Cup-shaped element is fraught with the disadvantage that in this case the charging port seems to be relatively heavy and awkward to handle.

This overcomes the disadvantages of the known device according to DE-AS 1083219. In this DoCoMo between the outer side of the machine and the dryer for linen, moreover, this depth is made in the form of a rim of soft elastic material having recourse to the drum inner side directed inwardly sealing edge for fastening the glass.

The disadvantage of this known hatch is that facing the drum with the Laundry sealing lips soft, stretchy side as a result of prolonged use and constant contact with lye soap can become porous. In addition, the soft elastic sealing edge can be displaced under the action of rotating linen. Moreover, with extended operation inevitably occurs more noticeable wear soft elastic sealing edges under the action of rotating linen. Over time these impacts worsen the necessary seal drum for washing. May even decrease the reliability of holding the glass between the sealing edges. In addition, when the collision area wash things with soft elastic sealing lip this thing can suddenly slow down, which can lead to overload and in a particular case to break things.

The objective of the invention is the creation of the loading door of the aforementioned type, otnositelnye body, and yet to prevent additional load to wash things.

According to the invention this problem is solved due to the fact that the synthetic material is a hard elastic material that sight glass along the entire length of the outer region curved in the direction of the area constituting the side wall, so that it forms a rounded glass ledge, and a sight glass on the outer edge of the glass ledge includes located obliquely to the inner surface of the sight glass annular connecting section, which is its upper end into firm engagement with the inner end of the segment constituting the side wall. Due to the properties according to the invention creates a relatively lightweight, durable boot lid which does not have a rotating linen neither inhibitory nor abrasive impact.

Particularly advantageous is that consisting of synthetic material section constituting the side wall, may be held in a more narrow range of tolerances than the casting of molten glass in this place (about 1/3 of tolerances for glass). This allows better use of the seal between the loading opening and a lip seal around the hatch.

Preferably the upper end saegusa groove on the inner end of the segment, constituting the side wall, thus providing a reliable connection.

Preferably the upper end of the connecting section is made by injection molding in one piece with the land constituting the side wall, resulting in the reduction of the number of separate elements, thereby reducing installation and storage costs.

Further decrease in the number of structural elements is possible due to the preferred embodiment of the outer end of the segment constituting the side wall as a single part in the form of the annular frame of the hatch.

In a preferred embodiment, the inner surface of the sight glass is made in the direction of the holes of the bowl convex, which increases the margin of safety glass.
