RELATED APPLICATIONS 
     This application claims priority from Mexican application Ser. No. MX/a/2010/05581, filed May 19, 2010, which is incorporated herein by reference in its entirety. 
     FIELD OF INVENTION 
     The present application relates to a door or cover for a household appliance with a sole glass piece and more specifically to a reversible door or cover for a dryer which has a single glass pane, as well as the assembly pieces for said door or cover. 
     BACKGROUND 
     It is common for door or cover assemblies for household appliances, especially those in washers and dryers, and more specifically in the field of dryers, to have a window with at least two layers, where as an example, the two layers can be two glass panes, an inner glass pane which is in contact with the textiles and an outer glass pane which can have contact with the operator, or yet a glass pane as an inner window and a thermoplastic polymer laminate such as polycarbonate as an outer window. The advantage of having two layers on the window of the door or cover of the dryer is that it can protect the operator from exposure to the high temperatures generated during the drying cycle in the dryer&#39;s interior, thus avoiding exposing the operator to possible burns by being in direct contact with the dryer&#39;s window. 
     Additionally, one of the problems which can arise on the doors or lids in the previous art is that the doors or lids of household appliances, especially of dryers, can be non-reversible. 
     It is common that the operator realizes after comparing his dryer that in light of its proximity to other objects, such as can be a wall, the opening of the door or cover be an obstacle. 
     Patents which have a double glass pane for dryers are known in the previous art. For example, U.S. publications Nos. 200402246 and 2005034486 and Korean publication No. 20030062172, make known doors for dryers with a window composed of two layers. It is common for washers to have a door or cover present with a single glass pane. For example, U.S. Pat. Nos. 6,665,984 and 7,032,350 make known a door or cover defined by a tempered glass bordered by an encapsulation similar to an open frame made of a molded and injected copolymeric/polymeric synthetic plastic material, preferably an acrylic/styrene/acrylonitrile mixed with glass beads with mica. The inner periphery of the encapsulation of the door or cover is relatively wide which securely adheres and reinforces to the outer periphery border of the tempered glass panel, an outer periphery skirt, a rear handle among others. 
     U.S. Pat. No. 6,766,596 makes known a door or cover, which includes a tempered for a household appliance, such as a washer or a dryer, which includes a tempered glass panel over an inner surface over which one or two inlayed borders are applied by a ceramic pressing means which define a substantially opaque periphery border which delineate a central area to be viewed through which the clothes in the dryer or washer can be seen when the door or cover is closed. A wide encapsulation molded by injection or border, surrounds the border of the tempered glass panel and creates a water seal for the same. A third means of ceramic pressing formed according to security instructions or rules are applied to the first or second means of pressing but are not discernible from the outside when the door or cover remains closed. When the door or cover is opened, the security instructions or rules are completely visible and readable. This invention makes known a first layer which is a glass pane and two subsequent layers of the pressing means, such as is shown in  FIGS. 6 and 7 . Additionally, as opposed to this patent, the present invention has a fastening means for the glass pane itself for horizontal load doors, such as those used in dryers and not washers as is shown in said patent. 
     Hinges for reversible doors are known in the previous art. For example, U.S. Pat. No. 5,253,433 makes known a mounting arrangement for a reversible dryer&#39;s door in which a hinge assembly annexed to the dryer cabinet&#39;s door includes at least two time hinges, each one having a fixed hinge sheet and annexed to the door and a fixed detachable sheet hinge annexed to the cabinet. Each detachable sheet has a pair of holes placed vertically. The reduced portion of the upper hole extends from the lengthened portion. The reduced portion of the lower hole extends towards under the lengthened portion. Mounting holes are provided in the cabinet&#39;s front walls on both sides of the access opening, aligned in accordance with the reduced portions of the upper and lower hole openings. The door is mounted by partially inserting a mounting screw in the upper part of the hole on the selected side of the cabinet. The lengthened portion of the upper opening on the sheet is passed through the mounted screw&#39;s head and allowed to drop. When the upper border of the hole&#39;s reduction portion bumps with the screw&#39;s pointed part, the door is aligned for the insertion of the remaining mounting screws. To make the mounting reverse, the door is disconnected and the screws annexed to the detachable screws from the cabinet are removed and the door is inverted and annexed on the side opposite the access opening as was previously described. Another document to consider is the summary and figures of Japanese Publication No. 2001009192. 
     On the other hand, safety clasps for reversible doors are also made known in the previous art. For example, European patent No. 0 610 824 makes known a safety clasp for a household dryer for clothes which has a lid for the door with a spring action closure mechanism. The closing plate undergoes a sliding action element and has a dual position security device to prevent the use, or to ensure the door when the appliance is turned on The dryer has a large opening and a respective door with a handle. It is reversible, as are the screws for the hinges or the door closure. The dryer is turned on only when the door&#39;s projection is turned oppositely and is completely pressed to the groove of the before mentioned opening. Other safety clasps of lesser importance are those made known in U.S. Pat. Nos. 3,991,520 and 7,159,910. 
     Thus, the previous art does not make known a door or cover for a household appliance, specifically for a dryer, which has a single glass pane and which is reversible. In the same way, previous art does not make known a method to reverse the door or cover for a single glass pane for a dryer. 
     BRIEF DESCRIPTION OF THE INVENTION 
     The present invention relates to a door or cover comprising a single glass pane which is reversible for household appliances, especially for dryers. It is known in the field, that when it is turned on, and in light of the high temperatures necessary to undergo drying, the dryer, specifically certain parts of the cabinet and the inner part of the dryer, such as the drum and the dryer&#39;s door or cover tend to elevate its temperature. Specifically, the temperature of these parts of the dryer is elevated by being in contact with the clothes which are being heated. It is common in the field that a space be provided to better visualize the inner contents of the drum, basket or similar to the door or cover of the dryer. In light of the vast majority of dryers being front loading, that is to say, the access to the drum, basket or similar is by means of a door in the frontal area of the dryers, it is common that this space to visualize the inner content of the drum be present in the frontal area. Thus this space to visualize the inner content does usually not have a height greater than one meter and can be easily accessed by different operators. Upon heating, the door also heats this space to visualize the inner content, which is why, if the temperatures in this space are not controlled, it is easy to burn the operator if he touches the space meant to visualize. 
     Thus it is desirable to have doors or covers for dryers with spaces to visualize the inner content of a dryer which are safe for the operators. In a similar manner, it is desirable to have doors or covers for dryers with spaces to visualize the dryer&#39;s inner contents which do not substantially increase the selling cost of said dryer. Thus, it is ideal to have doors or covers for dryers with spaces to visualize the inner content for a dryer which are easy to assemble and which contain few higher cost pieces. Additionally, it is desirable to use doors or covers for dryers with spaces to visualize which are reversible. 
     The present invention focuses on resolving all of the previously mentioned deficiencies in the same door or cover for the dryer. That is to say, the present invention&#39;s door or cover is a door or cover for a dryer with a low production cost, which has a space to visualize the dryer&#39;s inner content, which has a high safety factor for the operator, where the temperature levels of the parts which could potentially be in contact with the operator remain within the specified levels, and which has long durability and which is also reversible. 
     The door or cover assembly for dryers in the present invention comprises an inner door or cover, an outer frame and a tempered glass between the inner door or cover and the outer frame. The inner door or cover fastened unto the tempered glass by means of at least four retainers and at least four screws which fasten unto the retainers of the door or cover. The retainers exert a constant pressure on the tempered glass, pressure which is translated into force which said tempered glass exerts as a constant pressure unto a seal on the inner door or cover&#39;s inner face. The seal is coupled to the inner door or cover&#39;s inner face by a plurality of grooves distributed near the border or outer perimeter of the inner face, which anchor the seal to the inner door or cover&#39;s inner face. The compression forces between the inner door or cover and the tempered glass, and the back compression force between the cabinet, specifically the dryer&#39;s front panel, and the inner door or cover&#39;s seal, avoids air leaks from the dryer&#39;s interior and guarantees a uniform seal. Packaging is present between each one of the retainers and the tempered glass to avoid contact between the retainers and the tempered glass. Specifically, the packaging surrounds at least a part of the tempered glass border. Conversely, an outer frame is fastened to the inner door or cover by means of at least six screws distributed along the length of and close to the border of the outer frame and are received by holes on the inner door or cover. The handle is mechanically assembled to the outer frame. 
     The door or cover assembly for dryers of the present invention additionally comprises at least two hinges assembled unto the two lateral walls of the outer frame. Each one of the hinges is fastened unto the outer frame by at least two screws. Finally, the door or cover assembly for dryers of the present invention comprises two plates placed on the outer face of the inner door or cover, specifically in a part near the lateral border, substantially central on the outer face. One of the two plates is a plate with two grooves, while the second plate has at least three grooves. Both grooves of the first plate and two grooves of the second plate are grooves which allow for the fastening of the plates unto the outer face of the inner door or cover. One groove of the second plate is capable of receiving and fastening unto a safety clasp. When the door or cover is in a closed position, the safety clasp prevents the opening of the door or cover. 
     Thus, it is an aspect of the present invention to provide a door or cover for a dryer with a space to visualize the inner content of a dryer which is safe for use for the operators. 
     Another aspect of the present invention is to provide a door or cover for dryers with a space to visualize the inner content of a dryer which does not substantially increase the selling price of said dryer. 
     Another aspect of the present invention is to provide a door or cover for dryers with a space to visualize the inner content of a dryer which is easy to assemble and which contain few high costing pieces. 
     Yet another aspect of the present invention is to provide doors or covers for dryers with a space to visualize the inner content of a dryer where the doors or covers are reversible. 
     Other aspects and advantages of the present invention will become apparent when the description is referenced along with the following figures.

     DETAILED DESCRIPTION OF THE INVENTION 
     The use of the term “approximately” provides an additional determined range. The term is defined in the following manner. The additional range provided by the term is that of approximately +10%. As an example, but not limited to, is it states it is “approximately 25°”, the exact range lies between 23.5 to 27.5°. 
     The present invention refers to doors or covers for household appliances. Specifically “doors or covers” shall be mentioned from here on after solely as “doors  1 ”, however it should not be limited by any reason to doors for this invention, and it should be considered that the same characteristics are applicable for covers. The preferred household appliance for the present invention is household dryers  2 , such as can be seen in  FIG. 1 . However, other household appliances which use heat as their source of heating or drying can be included, such as ovens, dishwashers and industrial clothes dryers. Additionally, the materials used to manufacture the door of the present invention can be substituted depending on the household appliance and depending on the needs of the operator. For example, plastic parts used in the present invention can be substituted by metal parts if it is foreseen that the door will be subject to temperatures higher than the smelting temperature of certain plastics. The fastening means used in the present invention can be those that exist in the field, such as coiled, for example, like in conventional screws. Other fastening means available can be used, so that the type of fastening means is not seen as limitative. 
     FIRST EMBODIMENT 
     The following description makes general reference to  FIGS. 2 through 5A . 
     In the present invention, a door for household appliances is made known, preferably one for dryers  2 . The dryers  2  can be front loading, such as the one shown in  FIG. 1 , or rather can be top loading or inclined as was known in previous art. 
     The main parts of the door  1  are an inner frame  10 , an outer frame  20  and a tempered glass pane  3  between the inner frame  10  and the outer frame  20 .  FIGS. 2 and 3  are views in explosion which show the outer frame  20 , the inner frame  10  and the tempered glass  3  and the union between all these parts. Such as its name denotes, the outer frame  20 , when the dryer door  1  is closed is outwardly oriented in relation to the dryer  2 , while the inner frame  10  is inwardly oriented in relation to the dryer  2  when the door is on a closed position. 
       FIGS. 2 and 3  show the majority of the components necessary for the first embodiment. Thus, the inner frame  10 , the outer frame  20  and the tempered glass pane  3  which is found between the inner frame  10  and the outer frame  20  can be seen. Both the inner frame  10  as well as the outer frame  20  has a window  19 ,  23  in a substantially central part of said frames  10 ,  20 . The inner frame  10  has a first seal  11  applied which faces inwardly unto the dryer  2  when the door is oriented in a closed position, that is, the first seal  11  is placed on the inner face  14  of the inner frame and a second seal  12  is placed on the outer face  15  of the inner frame, same which faces the dryer&#39;s  2  exterior when the door is oriented in a closed position. The seal  11  is placed over a gutter which is found in the inner frame  10 . The tempered glass  3 , which is of a substantially lesser size than the inner frame  10  and of a substantially greater size than the window  19  of the inner frame  10 , is placed over a second seal  12 , while there are at least four retainers  13  fastened unto the inner frame  10  by means of fasteners  4 . The retainers  13  press the tempered glass  3  to the inner frame  10  and more specifically, the retainers cause the tempered glass  3  to be pressed with a force in the direction of the inner frame  10  and against as second seal  12 . The retainers  13  are preferably steel. Given that the retainers  13  will usually be made of a material which can scratch the tempered glass  3 , a packaging  16  is provided per each retainer  13 . Additionally, said packaging can also prevent noise by vibration between the glass  3  and the retainer material  13 , decreasing in the same way the magnitude of thermal shock between the glass  3  and the retainer  13 , which as previously mentioned, is preferably made of steel. The packaging will have the same length or be greater than the length of the retainer  13  to avoid contact between the retainer  13  and the tempered glass  3 . The packaging  16  surrounds the tempered glass  3  at least partly. The compression forces between the inner frame  10  and the tempered glass  3 , specifically between the tempered glass  3  against the second seal  12  in light of the pressure applied by the retainers  13  against the tempered glass  3 , and subsequently the inner frame  10  against the dryer&#39;s  2  cabinet, specifically the first seal  11  against the dryer&#39;s  2  cabinet, avoids air leaks from the dryer&#39;s  2  interior to the outside and guarantees a uniform heat seal in the dryer&#39;s  2  inner part. Such as is subsequently demonstrated in  FIGS. 16 and 16A , an outer frame  20 , capable of receiving and fastening to a handle  21  mechanically assembled to the outer frame  20 , is fastened to the inner frame  10  by means of the fastening means distributed along the length of and close to the border of the inner frame  10  and are received by assembly holes  34  on the inner frame  10  and receptor cavities  65 , possibly coiled, on the outer frame  20 . The outer frame  20  covers at least part of the tempered glass  3 , and thus also covers the retainers  13 , packaging  16  and second seal  12  among others. 
       FIGS. 4 and 4A  show how the tempered glass  3  is fastened unto the inner frame  10  by means of the retainers  3 . The retainers  13  are fastened by means of fasteners  4  against the inner frame  10 . Given that the retainers  13 , by means of the packaging  16  (if they are present), fasten the tempered glass  3 ; the tempered glass  3  creates pressure against the inner frame  10 . 
       FIG. 5  shows a cross section of the assembly between the inner frame  10  and the tempered glass  3 , while  FIG. 5A  shows in detail, what is shown in  FIG. 5 .  FIG. 5A  shows that a second seal  12  makes pressure against the tempered glass  3 . It also shows the relationship between the tempered glass and a fifth part  54  of the retainer  13 . Once assembled, between the tempered glass  3  and at least one part of the outer face  15  of the inner frame  10 , a hollow space is left EH 1  with the end purpose of allowing the flow of hot air and thus avoiding the door&#39;s  1  temperature to increase. 
     SECOND EMBODIMENT 
     In  FIG. 5B  a second embodiment can be seen. Specifically, in the second embodiment, several pieces can be dispensed with. Specifically, the retainers, the corresponding packaging for the retainers, the fastening means related to the retainers and the second seal, can be dispensed with. Specifically, over a gutter  30  of the inner frame, a constant silicon based strip  80  is provided. The strip has a width of approximately between 0.5 centimeters to 10 centimeters, and is deposited at a constant velocity approximately varying between 120 mm/second to 180 mm/second, preferably approximately between 135 mm/second and 160 mm/second and even more preferably approximately between 145 mm/second and 152 mm/second. The silicon&#39;s exit pressure varies approximately between 80 and 92 psi, more preferably between approximately 84 to 90 psi, and even more preferably approximately between 84 to 87 psi. 
     After the strip  80  deposit over the gutter  30 , the tempered glass  3  is deposited over the outer face  15  of the inner frame, specifically over the strip  80 , said deposit being at a constant pressure varying between approximately 0.001 kg/cm2 to 0.1 kg/cm2. The temperature at which this deposit needs to be carried out should be room temperature, preferably approximately at 25° C., with a relative humidity varying approximately between 40 to 55%, more preferably between approximately 45 to 52% and even more preferably between approximately 48 to 51%. 
     GENERAL OBSERVATIONS OF THE INVENTION AND OTHER EMBODIMENTS 
       FIG. 6  is a view of the outer face of the outer frame  20 . Similarly, in the figure, the handle  21  to said outer frame  20  can be identified. 
       FIG. 7  is a lateral view of both the inner frame  10  as well as the outer frame  20 . The hinges  22  can be identified, which by a means of fastening, shall be fastened to said frames  10 ,  20 . 
     Such as can be seen in  FIGS. 8 and 8A , on the outer frame  20 , specifically on a lateral  24  side of the outer frame  20 , two hinges  22  are placed. The hinges  22  are fastened to the lateral side  24  of the outer frame  20  by means of fastening means  4 . When they are in mounted position, the hinges  22  of the door will be near the dryer&#39;s  2  cabinet, while the handle  21  of the outer frame will be distant from the dryer&#39;s  2  cabinet. The hinges  22  can be seen with greater detail in  FIGS. 8A and 11A . The hinges  22  comprise two parts  25 ,  26 . The first part  25  is fastened to the door by fastening means  4  and by two holes  5  in said first part, holes  5  which are collinear with cavities  5  on the lateral side  24  of the outer frame  20 . On the other hand, the second part  26 , which is fastened to the first part  25 , is composed of two holes  6 , where each one of the two holes  6  is composed of two forms substantially circular, where a first substantially circular form is of a lesser diameter than the second substantially circular form. Both holes are substantially opposed, that is, while as an example, in the upper hole  6  the first form is in the upper part and the second form is in the lower part, in the lower hole, the second form is in the upper part and the first form is in the lower part. The inner frame  10  also has receptor cavities  9  to receive the first part  25  of the hinge. Specifically, the inner frame  10  has receptor cavities  9  in both of its lateral parts, which are substantially opposite between them. This can be seen in  FIG. 3 . 
     Such as can be seen in  FIGS. 8 and 8B  specifically for the first part of the plate- 17  and  FIG. 8C , in conjunction with  FIG. 14  specifically for the second plate- 18 , where a first plate  17  with two holes and a second plate  18  with three holes are fastened to the inner frame  10  in a plate receptor space  48 . Both plates are fastened to the inner face  14 , specifically on the lateral part  41  of the inner face  14  of the inner frame  10 . Two holes  5  on the first plate  17 , as well as two holes  5  on the second plate  18  are provided so that the fastening means  4  will fasten the plates  17 ,  18  against the door&#39;s inner frame  10 . Specifically, each one of the holes  5  in the first and second plate  17 ,  18  previously mentioned is collinear with a hole of the lateral part  41  of the inner face of the inner frame  10 . A third hole  7  of the second plate  18  is provided so that a safety latch  42  be fastened to the door assembly. The second plate  18  and the safety latch  42  can be seen in greater detail in  FIGS. 8C and 14 . Specifically, the third hole is composed by two substantially parallel sections  43  and one substantially transversal section  44 . The safety latch  42  is composed of legs  45  capable of crossing the two substantially parallel sections  43 . The safety latch  43  is also composed of at least two resilient parts  36  on each one of the legs  45 . When the legs  45  are crossing the substantially parallel sections  43 , the resilient parts  46  are compressed reducing the width of the safety latch  42 . When the legs  45  have completely crossed the substantially parallel sections  43 , the resilient parts  46  are expanded jamming the safety latch  42  to the plate  18 . The hole  8  is set to receive at least a part of the safety latch&#39;s legs  45 . Finally, the safety latch  42  comprises a head  47  which has a substantially oval shape and which closes the door  1  with pressure force to the dryer&#39;s  2  cabinet. 
       FIG. 9  shows the outer face  15  of the inner frame  10 . A gutter  30  can be seen which runs along the length and the width of the inner frame  10 , over which the second seal  12  or silicon strip  80  is placed.
