The present invention relates to a washing machine drum type, in which a cylindrical rotary drum having a tray, placed in a water tank so that the drum is oriented from the open front side towards the rear lower portion, with the axis of rotation is horizontal or tilted down. Linen is loaded into the drum through the hole made on the front side of the housing of the washing machine, the drum on the motor, realizing due to this, at least one of the stages of the wash, rinse or spin cycle.

Normal washing machine drum includes a sunroof, which is typically formed from a node of the hatch having a through opening, through which the user can see the Laundry, and a transparent cover mounted on the front side site of the hatch to close the site of the hatch. Such a washing machine drum claimed, for example, in pending published patent application of Japan No. 2007 - 68810 (hereinafter referred to as Patent document 1). Patent document 1 in particular reveals the transparent cover to the attached drawings, and the cover closes the front surface of the frame of the hatch to the outer rim of the frame. This conventional design creates the problem, i.e. the installed section of the latches, which are elastic hook transparent crystals is the scale of the hatch with the hatch frame and secure the cover on the frame of the hatch, can be seen from the front, so to some extent disrupted the beautiful appearance of the machine. To overcome this problem, in patent document 1 proposed frosted decorative plate, which is installed on the outer periphery of the transparent cover to create a good external appearance of the washing machine drum type.

However, the use of such decorative panels require additional components and stages of manufacture, resulting in increased manufacturing cost. The transparency of the cap currently is not required in the zone, not serving to monitor the wash, still placing decorative panels impairs the transparency of the hatch cover on the periphery of the cover. The result is spoiled by the quality, size and good appearance of the lid so that raises another problem, which consists in increase in cost and deterioration of compactness, as well as the appearance of the washing machine drum type.

The present invention solves the above problem and aims to create a washing machine drum type, in which the manhole cover is transparent up to its periphery, where the cover is elastically engages and is attached to the node of the hatch. In addition, this washing machine drum does not require additional composite of elements stored is or Assembly stages, so the washing machine can be compact and inexpensive. In addition, the fixed section is not visible from the outside, so the washing machine is compact, good quality and has a good appearance.

Washing machine drum type according to the present invention includes a cylindrical rotating drum with pallet which is placed in the water tank so that the drum is oriented from the open front side toward the rear lower side, whereas the axis of rotation is horizontal or tilted down. Linen is loaded into the drum through the hole made on the front side of the housing of the washing machine, the drum is driven by an engine, performing due to this, at least one of the stages of washing, rinsing or spinning. Luke is formed from the node of the hatch having a through opening, through which the user can monitor the wash, and a transparent cover located on the front side site of the hatch to close the site of the hatch. Numerous siteplease ears are made on the rear side on the periphery of the cover, while siteplease ears are backwards. Multiple locking holes of the mesh, which must be connected to siteplease ears made to the site of the hatch. Holes ears take in the site of the hatch and the elastic sacal who have siteplease ears with siteplease sections, which is provided with a node of the hatch, to prevent slippage of the ears. Ears and holes form numerous stationary section, to establish and secure the hatch cover to the node of the hatch. The surface of the cover corresponding to at least the stationary sections, has the shape of a surface that, at least, refracts and diffuses the light from the inside when the light penetrates through the lid.

The construction described above enables to prevent, at least, the leakage out of the water for washing, water for rinsing or spray produced during the spin cycle, during the relevant stages. In addition, the user can observe the wash through the transparent cover of the hatch and window, while the machine performs at least one of the stages of the wash, rinse or spin cycle.

Although manhole cover is transparent, at least in the areas corresponding to the fixed sections, the shape of the hatch cover allows light from the inside of the washing machine drum to be refracted or scattered when the light passes through the surface of the cap. Thus, the light reflected on the fixed sections, at least refracts or scatters as it passes through the surface of the hatch cover. In the above-described construction allows not to have a fixed section that it is desirable that were not vie the us outside, clearly in sight without any additional components or any additional stages of manufacture. As a surface, which, at least, refracts or scatters light from the inside, tankerenemy surface related to the polished surface, does not apply because the light reflected absently. The surface may be roughened surface, having instead a topography of peaks and troughs. The transparency of the regions of the respective fixed sections, spoiled little or internal structure, i.e. the fixed section is not displayed.

Hereinafter the invention will be explained in detail with examples of its implementation with reference to the accompanying drawings.

An example of a variant embodiment of the invention

Figure 1 shows a perspective view illustrating the basic design of the washing machine drum in accordance with the embodiment of the invention. Figure 2 shows a view in section of a washing machine drum of the type shown in figure 1.

Washing machine 1 drum in accordance with this embodiment includes a rotary drum 2 with the pallet, while the drum 2 is placed in the tank 3 to the water so about what atom, the drum 2 is oriented from the open front wall to the rear lower portion, with the axis of rotation is horizontal or tilted down. The user can download linen Laundry in the drum 2 through the hole 5 made in the front of the housing 4 of the washing machine, the rotary drum 2 is driven by the motor 6 in such a way that can be carried out at least one stage of washing, rinsing or spinning.

On figa shows a partial view in section of a washing machine drum of the type shown in figure 1, specifically the input/output opening for linen and Luke 5, closing the input/output aperture. On FIGU shows the enlarged view in section of the stationary section and its nearby area shown on figa. Figure 5 shows a partial and enlarged perspective view of parts of the front frame, shown in figure 4. Figure 6 shows the front view of the hatch cover of the washing machine drum of the type shown in figure 1.

Luke 5 shown in figures 1 and 2, is formed by the node 8 of the hatch having a through opening 7, through which the user can see the Laundry outside, as shown in figure 2 and 3A, and the transparent cover 9 hatch, installed on the front side of the node 8 of the hatch. Cover 9 hatch has numerous siteplease ears 9a, protruding in the direction of back and made integral with the lid on its rear surface the Dole periphery, as shown in figa and 4. Node 8 hatch has multiple locking holes 8b engagement, appropriate SitePlayer oscam 9a. Each of the locking holes 8b receives the lug 9a, as shown in figa elastically gears lug 9a siteplease section 8A to prevent slippage of the lug 9a, sets and locks the hatch cover 9 to the node 8 of the hatch. The above construction allows the hatch cover 9 fit snugly and close the node 8 of the hatch on the front side, the lid 9 of the hatch attached to the node 8 of the hatch. The cover 9 of the hatch has a mounting protrusion 41, as shown in figure 4, for connection with the installation hole 42 made to the site 8 hatch. Thus, the retaining hole 8b gearing, which is prepared for node 8 hatch, respectively, for numerous saralaya lugs 9a, not only for the installation of the protrusion 41, while retaining hole 8b for each of the available saralaya ears 9a.

The above-described mounting structure of the cover 9 of the hatch to the node 8 of the hatch demonstrates the idea is invisible from outside the location of the stationary section 11, formed of SitePlayer lugs 9a and the locking holes 8b of the engagement without compromising the transparency of the cover 9 of the hatch. More specifically, as shown in Fig.6, the side surface 9b of the cover 9 hatch, respectively, related at least to a stationary sections 11 made is regardless of form, the light inside can be, at least, refracted or scattered at the time when it passes through the cover 9 of the hatch. The surface of the parts 9b is made of such form, for example, as shown in figa and FIGU, and this form allows you to refract or scatter light, as shown by the pointers solid arrows or pointers dotted arrows on figa.

Design, described above, allows you to set the transparent cover 9 of the hatch on the front surface of the node 8 of the hatch and elastic hook lugs 9a, bent back along the entire periphery of the lid 9 of the hatch, with siteplease sections 8A locking holes 8b of engagement made to the site 8 hatch for securing the cover 9 to the node 8 of the hatch. When the cover 9 is attached to the node 8 hatch, part 9b of the cover surface 9 of the hatch corresponding to at least the locking holes 8b gearing and fixed sections 11, respectively, refract or scatter light from the inside due to their shape, although they remain transparent. In the light reflected on siteplease section 8A and the stationary section 11, which is formed from the locking holes 8b engagement and SitePlayer loops 9a, refracted or scattered, as shown by the directions of the arrows, while the reflected light passes through the side surface 9b of the cover 9 of the hatch. It is desirable that the structural elements would not be exposed to the outside, is such as saralaya section 8A, may not be visible because light is refracted or scattered, as indicated by the pointers solid arrows or pointers dotted arrows. This design requires no additional components or additional stages of Assembly.

Tankerenemy surface is not applied as a surface in parts 9b, since tankerenemy surface provokes diffuse reflection, which to some extent affects the transparency. Instead, use a rough surface profile of elevations and depressions, as she hides from the human eye design that you want to be invisible, such as siteplease section 8A, or prevents the reflection of the shadow of these structures.

Design, described above, helps to prevent leakage out of the water for washing, water for rinsing or spray produced during the spin cycle, during the relevant stages with closed hatch 5. The user can monitor the wash through the transparent cover 9 of the hatch and the opening 7, while the machine carries out the steps of washing, rinsing and spinning. In addition, as shown in figa, 3B and 5, part 9b of the surface along the periphery of the cover 9 hatch, match, at least, the locations saralaya sections 8A, the shape of the parts 9b surface modified with Sokh what anoniem transparency, so that the light reflected on the fixed sections 11 may be refracted or scattered. The result is preferably invisible structural elements, such as siteplease section 8A, remain clearly invisible to the human eye, at a time when the cover 9 of the hatch ensures transparency, or the feeling of transparency, and, in addition, the cover 9 Luke demonstrates good quality. In addition, changes made in parts 9b of the surface, and does not require any additional components or additional Assembly steps, so that the construction described above, does not cause increase in the cost of production of the washing machine drum. To be more specific, the change made on the surface includes, for example, a rough surface having a topography consisting of peaks and troughs, which prevents the reflection out of the shadow from the fixed sections 11, but excludes finely embossed surface, which promotes absent-minded reflection, which greatly impairs the transparency, which is enough to hide the internal structure of the human eye. The cover 9 of the hatch with parts 9b of the surface along the periphery, as shown at 6, and having the above-mentioned rough surface with a topography of peaks and troughs, demonstrates in some article the penalties decorative appearance.

The cover 9 of the hatch is made of plastic, in the General case, such as synthetic plastic. As shown in figa and 3B, the cover 9 of the hatch continues around the outer wall of the node 8 of the hatch and closes the node 8 of the hatch of his ongoing and covering wall 9c. End surface 9d covering wall 9c includes siteplease ears 9a made integral with the cover 9 of the hatch. Node 8 hatch includes along its periphery protruding wall 8d, protruding outward from the peripheral part of the node 8 of the hatch and having a stepped surface 8C opposite end surface 9d. The retaining hole 8b engagement continues through this protruding wall 8C from front to back. The above design allows transparent cover 9 of the hatch to go around the outer wall of the node 8 of the hatch and close the node 8 of the hatch so that the view of the human eye along an inclined line from the front or towards the front top inside can be blocked. In the transparent wall of the cover 9 of the hatch continues uniformly over a large area including the peripheral part, so that the washing machine 1 drum-type can exhibit the appearance top quality.

The stationary section 11 include the following design elements:

siteplease hole 9F as shown in figa and 3 is, or siteplease hook performed on the eye 9a; and

either one of saralaya sections 8A, made like the latch for the purpose of no return in its original position, when executed on the inner wall of the locking hole 8b gearing or rear open edge of the locking hole 8b gearing for elastic engagement with SitePlayer hole 9F or SitePlayer hook.

The above construction allows the hatch cover 9 to be attached to the node 8 of the hatch using elastic engagement with each other.

The node 8 of the hatch includes a frame 20 of the hatch, which contains the front frame 21 and the rear frame 22 made of synthetic plastic, and the side 23 of the transparent window is made of transparent synthetic plastic material and located between the front frame 21 and the rear frame 22. Front frame 21 and the rear frame 22 are located opposite each other located between the rim 23 of the transparent window, forming, thus, the aperture 7.

The protruding wall 8d of the node 8 of the hatch is made on the front frame 21, thus covering the wall 9c, continuing around the outer wall of node 8 hatch, usually flush with the outer surface of the protruding wall 8d. The rear frame 22 includes a flange 22A, facing outwards with their front end for a snug fit to the front frame 21. The flange 22A is connected with the mouth of the SIP 21A on the rear inner side of the protruding wall 8d. This design allows the frame 20 of the hatch to be integrated in a single unit with the front frame 21 and the rear frame 22. In this case, the front frame 21 is elastically engaged with the hatch cover 9, and these two elements can be a single element, or between the rear frame 22 and the front frame 21 is a side window 23, and these three elements may be held as a single item. Then cover 9 is mounted on the front frame 21 for elastic engagement with each other, and they can be attached to each other. In addition, the covering wall 9c of the cover 9 of the hatch is usually flush with the outer surface of the protruding wall 8d, so that the outer surface 9f of the cover 9 Luke continues on a large area, including volumetric region, and simplified. The rear frame 22 includes a flange 22A directed outwards at its front end for mounting on the front frame 21. The flange 22A is connected with the ledge 21A inside the rear end of the protruding wall 8d. The outer wall of the rear frame 22, thus, is placed inside the exterior walls of the cover 9 of the hatch and the front frame 21 so that the area seen from outside when the cover is closed 9 hatch, gives less illegible picture for users.

Part 9b of the surface located on the hatch cover 9, respectively, at least the stationary sections 11, changed its form to generate the, so the light from inside was refracted or scattered when the light passes through the cover 9 of the hatch. This modified form of the surface can be one of the following forms: (1) in the form of an annular or arcuate grooves cut in the radial direction, as shown by the directions of the arrows of dotted lines on figa, (2) a circular form or in the form of wavy arc cut in the radial direction, as shown by the directions of the arrows of solid lines on figa, or (3) rough surface with peaks and troughs, made it and continued in any direction. Use one of the above forms on parts 9b of the surface can prevent the vision from the outside of the fixed sections 11, including siteplease section 8A, due to the above relief, which does not impair the transparency. Part 9b of the surface should not be exposed to the process of applying a thin wall in order to not impair the transparency. Thus, for example, a topography of peaks and troughs, continuing in any direction must have a greater roughness than the relief notch.

The construction described above will be detailed hereinafter. As shown in figures 1 and 2, the housing 4 of the washing machine includes an inclined surface 4A, aimed up at the top of the front part, with all the input/output hole 31 for white which I made on this inclined surface 4A. Luke 5 mounted on hinges at the inlet port 31 to open and close the inlet opening 31, and is made round, as the inlet 31. Front frame 21 of the frame 20 of the hatch is molded, for example, polypropylene, and the rear frame 22 is molded, for example, of polypropylene, having a greater chemical resistance than the first. The side 23 of the window, made for example of glass, and the lid 9 of the hatch is made, for example, from transparent ABS plastic. The installation of the protrusion 41 allows you to determine how easy it is to install the hatch cover 9 on the node 8 of the hatch so that it was not possible to improper installation. This simple installation of the cover 9 of the hatch on the node 8 of the hatch may be preferable to resolve the question of how should be set cover 9 hatch, thus, the cover 9 of the hatch can be installed without defects. Large transparent area obtained on the hatch cover 9 to 5, and, in addition, a fixed section 11, including siteplease section 8A, which gears the hatch cover 9 with the node 8 of the hatch with the hatch cover 9, it is impossible to see outside of the washing machine 1 drum type rotary drum which is horizontal or tilted backward.

Washing machine drum type according to the present invention allows the user to observe the wash through the transparent cover and the box, when closed down, at the same time prevent the I leak out water for washing, water for rinsing or spray. In addition, a transparent cover mounted on the front surface of the node 8 of the hatch and elastically engages with the hub 8 of the hatch, and, in addition, the outside is not clearly visible structures, which preferably should be invisible from the outside, such as a stationary section including siteplease section.

To be more specific, part of the cover surface 9 of the hatch are, at least to the respective fixed sections, with part of the surface remains clear, though, change the shape of the surface with the purpose of obtaining refraction or scattering of light transmission, reflected on siteplease section. This design allows not to impair the transparency or clear picture through the hatch cover 9 and, in addition, to reduce the transparent area, while ensuring that the invisibility of the internal structure from the outside. The result is a high quality washing machine drum. To get this type washing machine a drum type with good quality not require any additional components or additional production steps, thus, not expected and increasing rates of production. Part of the surface relating at least to the respective fixed sections are not subjected to the process of applying a thin relief, which affects the transparency is durability due to diffuse reflection, but use the topography of peaks and troughs, which protects the fixed section, including siteplease section, to be seen outside. The above relief provides a clear picture, as well as good quality, giving, thus, the washing machine drum-type decorative finish and good looks.

Washing machine drum type according to the present invention allows to obtain a large transparent area on the hatch cover 9, which saralaya section elastically gears cover 9 of the hatch with the node 8 of the hatch, and, in addition, this saralaya section is not clearly visible from the outside. The hatch can be changed, as described above, at no additional cost. Washing machine drum, thus, can be used by users due to its compact size and good appearance.
