This invention belongs to the kitchen electronic appliances, specifically: food toasters
This invention is for a bread and tortilla heater. Nowadays, there are many kitchen appliances for tortilla heating, such as the appliances shown in art documents before this: U.S. Pat. Nos. 6,546,844, 6,205,911, 5,584,231, 2,562,535, 7,094,991, 6,116,150 y US 201414773753. However, these appliances shown previously are complicated to manufacture and none of them is adapted, for heating a slice of bread such as the appliance of this invention.
On the other hand, we have the common bread toasters, which have mechanisms, usually actioned by springs placed together to move a base support to receive the bread and move it up and down, using either a lever or an automatic mechanism actioned by a clock.
This type of toaster, generally speaking, contains a couple of grids; one on each side inside of the compartment and between them, it warms the bread up. Such grids are vertical, one in front of the other one, have the function of centering, and holds the bread slice thanks to the mechanism, usually made of springs when the base that receives the bread is pulled down.
The issue with these kind of toasters that do not allow the tortilla to be warm or toasted is the base support. They have a base with flanges in a “V” form separated from each other that cannot hold the tortilla down properly. Some empty spaces between the flanges and the grids in which some thin meal or the tortilla itself can get stock. Other bases have a flat form that does not provide the tortilla with a support point, centered to avoid the tortilla from folding or getting stock when the support is moving between the grids. This invention overcomes any inconvenient mentioned previously of the known toaster's bases, providing to a flat and soft item, such as tortillas. The proper support, due to its form and the distribution of the grids make the base support adapted in the convenient form of the tortilla avoiding gaps between the flanges and the grids of the toaster. The tortilla gets introduced or is slided up, it will not get folded, rolled up or stock inside the toaster compartment due to the strength with which the tortilla is moved, or by getting stock in the gaps formed between the flanges and the grids in the known toasters.
Another issue of the conventional toasters that do not allow to heat tortillas up, is that such grids, by their distribution inside the toaster form gaps or lumps. The lumps, when sliding up the base on which the thin and soft item is, get it stock on the gaps or lumps formed by the grids and the outside of the toaster. The previous problem is solved thanks to this invention with a bridge with sliding properties that connects the grids, also with sliding properties, with an edge of the outside opening avoiding gaps or lumps, in which a bread or another soft and thin meal can get stock or folded.
Another problem with toasters is that the grooves that guide and support the axes of the grids that hold bread or tortilla do not approach each other enough. Both grids come together completely and totally to each other, which serve to firmly hold a tortilla and avoid bending, which does not happen in current roasters, therefore, to solve this problem, in this invention will be appreciated from the drawings that such slots are next to each other ensure that the grilles can join together completely and totally.
Another disadvantage of this kind of toasters is that the vertical arrangement of the racks and the support base does not help in the weight distribution of the tortilla to avoid folding to use its weight on its perimeter when inserted vertically. To solve this problem of weight distribution, this invention has a slope, which allows to distribute the weight of the tortilla with no damage. Although U.S. Pat. No. 6,205,911 mentions a toaster having an inclination. The inclination less than 45° to the horizontal base makes it difficult to introduce a soft, flexible pancake having to use both hands to do so because, with such a tilt range, no gravity is used so that the tortilla is introduced easily to fall under its own weight but folded; in the case of vertical toasters. Besides the ones mentioned before, another disadvantage of the patent is that the grooves where foods can be placed are limited to a measure 1, 27 cm wide, whereby such appliance does not solve the problem of changing the thickness of a food other as the case of a bread tortilla as does the invention described herein.
Also, some toasters have a tray at the level of the base of the toaster and distant from the slots where the food is pushed when it has been heated. If the heated food is a soft tortilla, such item hangs through the opening and in contact with the hot slot or it may fall, which causes the tortilla bend or break, which is an undesirable situation. This problem is solved by this invention by a continuous external receiving tray (not heat conducting) to the opening of the inner casing, thus is preventing tortillas from hanging by the opening of the inner casing that is commonly heated excessively. Besides being practical, the receiving tray of the invention also offers the advantage of preventing the user from burning, since the food item is there, it is hot, and so it can remain for a moment on the tray before the customer takes it.
As mentioned above, known in the previous art toasters, they have mechanisms crimping food through grids spring-loaded, either alone joining the tops of such grids or the lower or upper parts together. However, this can be a problem for a soft, thin as a pancake item because it can bent. Therefore, to solve this problem, the invention described here has the characteristic of good timing to lower the main support base with the tortilla or bread. The lower portions of the grids and shortly after their tops, and when putting the support base up, the tops of the gratings are separated first and then the lower parts, thus, by the time the tortilla comes down, this is pressed and immobilized to prevent curling or bending from the moment it begins to fall.
Additionally, this invention provides a devise that known toasters do not have, as it provides the function of making precise cuts partially when the grids press the item.
This invention covers the need to prevent one or more tortillas with different characteristics (thickness, flexibility, hardness, weight and moisture) when heated or toasted, move freely, bending or rolling up. At the same time, provides economic advantage because the same device is able to adapt both, heating and toasting food thinness and softness of a tortilla as the thickness and softness of a bread, with the additional advantage of toasting tortillas with partial cuts preset.
The item described is a toaster that useful for food items as thin and soft as a tortilla and as thick and hard as a bread, with the additional advantage of toasting tortillas with pre-established partial cuts. Such device includes one or more cases that have one or more openings on the superior part. Such cases have a leaning with a rank between 45° y 89° in regards to a horizontal base, such toaster has one or more slots placed in vertical walls of the cases through which superior and parallel axes go, forming an inferior and superior grid to hold an item. The grids are parallel to the walls of the cases forming a bridge with an edge of the slots, avoiding gaps or bumps
A central axe provides the grip for the tortilla. The axe can be between the inferior and superior grids, passing through the slots that are in the parallel walls of the cases. Such axes includes one or more tabs on it, in which a part of those tabs is next to the inferior grid, and another part of them is next to the superior grid. The tabs of the central axe have a space between them so that several slide rods can form a grid.
The toaster described here, includes a rest position in which the upper and lower grids are apart from one another without imprisoning a foodstuff, one or more tabs disposed along the central axis reach the grids, and the central axis is close to the openings. The toaster described here also includes a toasting position in which the upper and lower grids approach for pressing and centering a food item between, at least, one source of parallel heat with the parallel walls of the case, for which the central axis presents closeness to the bottom of the cases. The inferior and superior grids can have a plurality of rods, or by a smooth surface, which can present holes.
For this invention to be very particular, the toasting position can include the feature of closing in the superior and the inferior grids, using the inferior and then the superior axis. Also, the grids disposition in which the superior rods do not interfere with the inferior rods when coming closer. The toaster can also have one or more sharp ends on the superior grid.
The characteristic details of this bread and tortilla toaster are in the next description and the drawings attached.
Next, details of the invention in reference to the figures, which help better to understand the new aspects of it.
The main purpose of the inclination between 45° and 89° is to distribute part of the weight of the tortilla (14) on the inferior grid (16), so that it will not bend when holding its weight on the perimeter like it would happen in a toaster in which the grids are at 90°. Such inclination over 45° is also useful to avoid for a soft tortilla from folding due to it getting too close to the grids or the opening of a toaster, because of the inclination less than 45°, which does not allow to use the weight of the tortilla when placed.
In
The receiving support or tray (19) has the function of receiving the tortilla and keep it from hanging when the toasting process is over and the tortilla comes out of the toaster, keeping it from breaking or folding wrongly. This receiving support (19) also offers the advantage of avoiding burns, because when the food item comes out toasted, it is hot, so it can stay there on the tray to cool down. Such support is preferably in curve form although it is not limited, and could be straight or partially curved.
Also, between the movable grids (16) (17) there is a support, a primary base (20) on which the bread or tortilla is received (14). Such base, together with the receiving support (19), the “L” bridge (18), the edge (13′) of the superior opening (13) and the inferior grill (16) form a surface with no bumps or gaps in which a tortilla could get stock.
From the previous information, it must be understood that the toaster here shown can include one or more exterior casings (10) that contain one or more elements mentioned above or below described.
The toaster described here includes two positions for the movable grids (16), (17) and for the base support (20), a rest position and a toasting position.
Preferably, the angle of leaning of the tabs (21) in regards to an imaginary axis parallel to the grids (16) (17) marked with dotted lines in
If the leaning angle of the tabs (21) on the inferior's side grid (16) was not minor than the angle of the tabs (21′) on the superior's grid side (17), a food item as thick as a bread slice would not be equally held on both tabs (21) (21′). Therefore, the bread slice would not be between the grids correctly during the toasting process.
Nevertheless, the tabs (21) of the inferior grid (16) also may have equal or different leaning angles related to the tabs (21′) on the side of the superior grid (17) parting from the imaginary parallel line to the grids.
In a preferred way to carry out the invention shown in
The superior axis (22) (22′) and inferior ones (23) (23′) can have an optional edge stop (39) (in
On
After this, once the central movable axe (30) gets to the V shaped point and starts pulling the superior metallic elastics (24) (24′), the superior axis (22) (22′) of the movable grids get close until the central one (30) gets close to the bottom of the internal case (12) or close to the inferior axis (23) (23′). It happens in a toasting position in such a way that both grids (16), (17) get as close as possible to each other to hold and center the bread slice or tortilla (14) like in
The action of getting close to each other, first, the inferior axis (23) (23′) and then the superior ones (22) (22′) of both grids explained above is very useful. When the main support base (20) that holds the tortilla (14) slides to the bottom of the inside case (12), the tortilla is pushed to the superior grid. The tortilla (14) starts taking a flat shape after getting in contact with the main support base (20). Gets in contact with the tabs (21) of the inside grid (16) all the way to the bottom of the inside case where the tortilla goes completely flat for being hold tight with two grids (16) (17).
Despite the preferred way to carry out this invention,
In another way of carrying out with the invention (not shown), the resting and toasting positions can be possible using a metallic elastic wire, in which one end is attached to a fixed hook on the inside casing wall. Such holder is on the superior's side grid and on the central axe slot guide's side; such wire on its other end is held to the inferior axe of the inferior grid. Also, a metallic elastic wire is backwards on the opposite side that holds the inferior axis of the superior grid. The wires make the shape of an X that matches with the guiding slot of the central axis, such wires are pushed and pulled by the flat bar incorporated to the movable central axis. The wires pull the inferior axis of both grids until they are completely together and go back to the resting position due to a tensor when the flat bar is removed.
Also, the heat sources (15) are parallel to the grids (16) (17) and the superior metallic elastics (24) (24′) hold the superior axis (22) (22′) of both grids (16) (17).
The main function of the thin tabs that are in the center (33) is to guide, stop and hold the tortilla. Such thin tabs (33) are the same as the partially curved tabs (21) on the inferior grid's side (16) and straight ones (21′) on the superior grid (17) as mentioned before on figure's 1 description, guiding with its curved shape the soft and thin tortilla providing support and direction to avoid folding or breaking. However, how it was mentioned before, the shape of the thin tabs (33) is not limited, so they can also be straight as
The wide tabs (32) and thin tabs (33) have a length that allows them to reach the grids (16) (17) and preferably go through them, when they are in the resting position; with the previous information there is the advantage of no gaps or bumps through which an item as thin and soft as a tortilla could jam.
In other words, the closeness of bot grids (16) (17) during the toasting process is given by the thickness of the central mobile axis (30) and by the horizontal separation between slots, superior (28) (28′) and inferior (29) (29′).
For more clarity,
It is necessary to mention that such distribution of the axis (22) (23) with the rods (18) is the same for the inferior grid elements (16). This same figure shows how the rods of the “L” bridge (18′) fit with the tabs (32) (33) distributed along the mobile axis (30) and joined they make the central base support (20). The base support is assembled to the mobile carrier (35) that goes through the pedestal (35) when the lever goes up or down (36) which causes the movement of the axis (22′) (23′) of the grid (17) due to the metallic elastics (24′) (25′) attached to the axis (22′) (23′).
On the other hand, the bread and tortilla toaster can have different devices or mechanism points that regulate the height of the base support (20) by the mobile central axis (30), to adjust it to the height of the food item that will be toasting. As an example of this mechanisms, there can be in an optional way a plurality of horizontal slots (not shown) disposed in the vertical slot (31) through which the central axis passes by (30).
In an additional way to carry out the invention, the body of the inferior grid (16), in the cases that
Additionally, such inferior tray (42) like
On the other hand, the inferior tray (42) and the superior grid (17) can be still, so that the central mobile axis (30) descends and ascends along the main base support (20) and its tabs (21) (21′), according to the mode in which the invention is carried out.
As an option, the configuration of the inferior grid (16) mentioned before, just like
The current invention is for not only warming up bread or tortilla but it can warm one or more tortillas at the same time, or any type of food as long as the mechanisms mentioned before can receive it and expel it.
Finally, the language used to describe this invention has the main objective of legibility and instruction but not to go around the inventive matter. Therefore, the objective is not to limit the reach of the invention due to the written description, but for any of the following claims.
