In this way, a simple manufacturing door and a lower cost washing machine are achieved.

Description

FRONT LOAD WASHING MACHINE DOOR AND WASHING MACHINE WITH SUCH DOOR

FIELD OF THE TECHNIQUE

5
The invention is in the field of front loading washing machine doors that have a door frame, a concave element with an edge connected to the door frame and, a lenticular element that closes the concavity formed by the concave element forming a recess in the door and in the field of the front loading washing machines closed with doors like the one of the invention.

10
STATE OF THE TECHNIQUE

fifteen
Patent application W02009 / 112511 describes a front loading washing machine door having a door frame, a concave glass element with an edge connected to the door frame and a lenticular element that closes the concavity formed by the concave element forming a hollow in the door.

20 25
The Spanish utility model ES U223520 describes a door for front-loading washers made in one piece with a single transparent material. The door has an annular part that is arranged on the outside of the machine frame and a concave area that protrudes into the machine. Once the door is manufactured, the annular zone is subjected to an opalescent treatment, on one or both sides of said zone, to hide the mechanical support and locking parts of the gate. The memory of this model also mentions the possibility of maintaining the transparent assembly, revealing from the outside the technical components, thus obtaining a particular "machine" effect that could be aesthetically appreciable. We see therefore that this door, like the one proposed in the object of the search, also has no frame or trim and can be completely transparent. The door is manufactured entirely together with the closing element and the hinge fixing element.

JO
A door for washing machines of simplified construction, similar to the previous one, is the one described in GB 941134. Said door is made of transparent plastic and in one piece and subsequently the peripheral ring is subjected to a treatment that makes it opaque, so that only the

center circumference is transparent. In this case, the hinge and the handle are also completely molded with the door in its manufacturing process.

5 l a
The utility model ES U1015460 describes a door for washers and dryers in which the frame has been removed, so that the door consists only of a transparent cupped element, which can be made of glass or plastic, and a trim (in the memory is called the aesthetic frame) of plastic material that hugs the edge of the element that is attached along its entire perimeter. This element can be molded directly astride the edge of the cup-shaped element or molded separately and fixed to the edge later. It is noted that said bezel would be assimilable to the anti-shock bezel to avoid sharp edges and protect the glass. In the ES U1015460 model nothing is mentioned about the form of

joining said window to the hinge and latch elements.

DESCRIPTION OF THE INVENTION

fifteen
The object of the invention is to have a front loading washing machine door with improved energy efficiency characteristics, simple manufacturing and reduced cost and a front loading washing machine with a door with said characteristics.

twenty
This object is achieved by a front loading washing machine door comprising a door frame, a concave element with an edge connected to the door frame and a lenticular element that closes the concavity formed by the concave element forming a recess in the

25
door, where the door frame, the concave element and the lenticular element are made of a piece of plastic injected through a gas injection process.

30
A door of this type offers an improved configuration in terms of energy efficiency since the chamber formed by the cavity is a thermal insulator in high temperature washing processes. In addition, in the injection of gas-assisted plastics, especially nitrogen, this gas is injected at high pressure in the molten polymer mass, empties the central part of the piece and presses the molten material against the mold surface. After solidification of the material, nitrogen is evacuated from the mold cavity. The result is a door with better characteristics compared to those of a solid door. The door is lighter with virtually the same resistance, it is 3

It saves plastic material, has shorter production cycles thanks to faster cooling, the resulting door has no mark due to plugs in places of material accumulation and better accuracy in the dimensions of the door is obtained.

To fix the door to the frame of the washing machine, to fix a handle assembly or to incorporate any element to the door, it can have inserts of other material embedded in the plastic of the door. The inserts may preferably be metallic or ceramic in which the elements necessary for their function are fitted.

It is possible to assemble a handle assembly directly on the front face of the door frame or in a front recess made for that purpose on the front face of the door frame, with a handle and a latch protruding from the rear face of the door frame. An emptying in the rear face can also be carried out a subsequent emptying in which, for example, a hinge element of a hinge assembly fits. One way to fix the hinge assembly is to house the hinge shaft (the part corresponding to the bushings) inside the door frame and then cover it with a small sheet. The rest of the hinge is attached to the front panel of the washing machine. Another way to mount the hinge is by means of a two-part hinge composed of a mobile hinge and a fixed hinge joined by a pin. The mobile hinge would be mounted on the door and fixed on the panel. A vertical pin would be the connecting element and, in turn, the axis of rotation of the hinge assembly.

The cavity defined by the concave element and the lenticular element can also extend at least part of the interior of the door frame making it even lighter.

In another embodiment, the handle is made of one piece with the door during the same injection process so it is provided that either the latch also or an insert made as a latch is embedded protruding from the rear face of the door frame. This simplifies the manufacture of the door even more.

and to make the inside of the drum of the washing machine visible, the door can be made of transparent plastic. And to make it more resistant or aesthetically fit better in the machine, it is provided that at least part of the front face of the door frame is covered by an element

Scratch and / or chemical resistant protector. Also the protective element can be made as a ring in ABS plastic glued, clipped or welded to the front face of the door frame.

The main advantage of this technique is the integration of several pieces into one. In this way, the complexity of the door assembly is reduced. Said decrease in complexity entails a reduction in the cost of material and, mainly, in the cost of assembly. Therefore, the overall cost of the set decreases.

An additional advantage is the decrease, both in the amount of the investment, and in the period of execution of the necessary molds and tools. In addition, the energy consumed in the process is much lower.

DESCRIPTION OF THE FIGURES

Other advantages are taken from the following description of the figures. In the

Figures show an embodiment of the invention. The figures, description and claims contain numerous features in combination. The expert will also advantageously consider the characteristics individually and will gather them in other reasonable combinations.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Figure 1 shows a cross-section of a door 1 that closes a loading mouth of a front-loading washing machine made of a plastic part with an internal cavity 5 enclosed by a concave element 3, a lenticular element and a door frame 2. With the door 1 in the closed position in the machine (not shown), the concave element 3 is introduced through the loading opening of the machine, adjusting with a rubber seal of the loading mouth, sealing it tightly. The door frame 2 is on the outside of the frame of the washing machine.

The door has a handle 61 on a front face 21 of the door frame 2

and an insert 62 as a latch embedded in the door frame plastic

protruding from the rear face 22 opposed to the shooter.

On the other side of the door 1, it has a hinge element 7 fixed 5 screwed to the door frame 2 by its rear face 22.

The front face 21 of the door frame 2 is covered by an opaque protective element 8 that conceals the mechanical elements of the door and in turn protects it from scratches or chemical attacks of, for example, the cleaning products used during the washing process of the washing machine.

10 A schematic section of the door frame 2 covered with a protective element 8 of a door of the invention is shown in Figure 2. On the front face 21 of the door frame 2 a front recess 24 has been made in which a handle assembly 6 is assembled.

The handle assembly has a handle 61 protruding from the perimeter of the

15 door and a latch latch 63 protruding through an opening of the rear face 22 of the door frame 2. The assembly handle 6 can rotate about an axis connected to inserts (not shown) embedded in the plastic of the door 2 shaped frame of macaroni where you can turn.
