Oven door structure

The present invention proposes a technique for improving the door of the oven for cooking food, in particular propose a configuration that can be preferably applied to the mini-oven. In forming the front door of the oven, an upper plate opening gap is formed on the front surface of the upper body of the oven, and an "a" shaped cover frame part which covers the upper plate opening gap is formed on the door of the oven. It is easy to enter and exit the shelf inserted into the oven by enlarging the opening, and to easily determine the cooking degree of the food to be cooked, and to provide a complete seal so that the smell of the food does not leak out of the oven during cooking. An oven door structure.

In general, the oven is used for easy cooking of food. In the case of a mini-oven, the shape is similar to a microwave oven, but the structure of the door is generally opened and closed in a form in which the door is hinged from top to bottom as shown in FIG. These ovens are used to cook pizza, bread and the like because they can impart a separate ripening function.

The following describes the general configuration and operation of the mini-oven that is commonly used in the past. As shown in FIGS. 1 and 2, the mini-oven has an outer case 100 for accommodating all components, a plurality of shelves 101 for placing food on cooking, and an open front face. It is provided with a cooking chamber 102 in which food can be put and cooked. Here, an oven heater 109 for heating food to an appropriate temperature, and a blowing fan 110 for circulating the air heated by the oven heater 109 into the cooking chamber 102 is provided.

In order to put food in the cooking chamber 102 and to be closed from the outside during cooking, the door 103 of the lower opening type is supported and installed by a rotatable shaft, and the cooking chamber 102 can be opened without opening the door 103. It consists of a glass window 104 and a handle 105 for viewing the inside.

In addition, the bottom of the cooking chamber 102 is provided with a rotating plate 106 driven by a motor (not shown) to evenly apply heat to the food. On one side of the front part of the outer case 100, a temperature sensor (not shown) senses the temperature in the cooking chamber to set a temperature and time for the temperature in the cooking chamber 102 to be maintained at an appropriate temperature and maintained for an appropriate time. The control panel 107 and the operation button 112, the display unit 108 for displaying the set temperature and elapsed time, etc., and a cooling fan for cooling the outer case 100 at the rear of the outer case 100. 111 is provided.

In the conventional mini-oven, the food is placed on the shelf 101 or the rotating plate 106 in the cooking chamber 102, the door 103 is closed, and the switch of the control panel 107 is operated to control the temperature and the appropriate temperature. By setting the time, the food can be cooked.

However, the conventional mini oven has a problem in the structure of the door. In other words, in opening the door, the handle is opened in a horizontal state on the upper part of the door, and the hinges formed at both ends of the lower left and right sides of the door are opened. The grill shelf is removed from the cooking chamber of the oven. Hard.

There is a lot of food for cooking at the top of the shelf, because the top plate of the oven blocks the cooker's vision and does not recognize the food accumulated at the top of the shelf without having to insert or remove it. Therefore, in the case of the conventional mini-oven, a problem that the upper portion of the food on the shelf is caught on the inner circumferential surface of the oven body is often encountered in the process of extracting the food. This was more serious when cooking meat or bread with high food.

In addition, in the case of the conventional mini-oven, gas leaks from the inside of the oven to the outside through the open gap of the door when cooking food. As the oven continues to be used, the doors are repeatedly opened and closed, thereby gradually loosening the doors. In the case of the conventional mini-oven, as the use period elapses, an open gap is generated in the door, and there is a problem that smoke or smell leaks out when cooking food through the open gap.

The present invention proposes a technique for improving the door of the oven for cooking food, in particular propose a configuration that can be preferably applied to the mini-oven. In forming the front door of the oven, an upper plate opening gap is formed on the front surface of the upper body of the oven, and an "a" shaped cover frame part which covers the upper plate opening gap is formed on the door of the oven. It is easy to enter and exit the shelves inserted into the oven by enlarging the opening, to easily determine the cooking degree of the food being cooked, and to provide a complete seal so that the smell of the food does not leak out of the oven during cooking. An oven door structure.

The present invention relates to a door structure that can be particularly preferably applied to a mini-oven, and looks at in detail with reference to the configuration and its effect of the present invention [FIG. 3] to [FIG. 9].

First, the front is opened and the body 10 is formed in a hexahedral shape to form the appearance of the oven 100, the hinge 21 is fastened to the front opening 11 of the body 10 in the lower left and right sides There is a door frame 20 is coupled to the protruding hinge 21 and the handle 22 protruding toward the front of the top, there is provided a glass panel 30 that is fitted to the inside of the door frame 20. The upper end of the door frame 20 is bent in a "b" shape is provided with a cover frame portion 40 is formed so as to cover the upper plate opening interval 12 in which the upper plate front portion of the body 10 is cut. Therefore, these are combined to easily guide the entrance and exit of the grill shelf (1).

That is, the front part of the upper plate 15 forming the body 10 of the oven 100 is cut to form an empty space part, which is called the upper plate opening interval 12. The upper plate opening interval 12 enlarges the opening of the front door of the oven 100, so that the front portion of the upper plate is cut off, and thus the opening portion is enlarged to a part of the front surface and the upper surface.

This small magnification can result in significant functional magnification, especially in the mini-oven 100. That is, when the cooked food is put out of the grill shelf 1 on which the cooked food is placed or put into the oven for cooking food, the food placed on the shelf 1 is not caught by the upper plate 15 of the body 10.

In the case of the conventional oven without the top opening gap 12, the higher the height of the food wrapped in the shelf (1), the more serious this problem, when the top of the food enters the food through the opening of the door (15) ) Hanging on the end of the top plate (15) the inner circumference of the food, or spilled food will occur.

In order to solve this problem, the front part of the upper plate 15 is cut off to form a separate upper plate opening interval 12, and to make the food more easily accessible by making the most of the gap.

Then, the operation of the present invention will be described. It is similar to the conventional mini-oven in that the body 10 constituting the mechanism, the glass panel 30 for viewing and seeing food, and the shelf 1 to be inserted therein.

However, the door frame 20 has a hinge fixed to support the glass panel 30 to the body 10, but the cover frame portion 40, which is the upper end of the door frame 20, is bent to the letter "a". By maintaining the, it is characterized in that the top plate opening interval 12 to completely accommodate and wrap. Since the upper plate opening interval 12 of the body of the oven 100 is formed, the cover frame portion 40 is bent in a "-" shape unlike the other ovens 100 so as to completely cover the open portion. It is.

Accordingly, in the process of removing or inserting the grill shelf 1 as shown in FIGS. 3 and 6, the shelf 1 is supported through the end of the cover frame portion 40 bent by the letter “a”. It is easy to add spices or to secure the location to be cooked. It is easy to perform other tasks by using a hand other than the shelf 1 held by one hand so that the shelf can be firmly supported against gravity.

And the present invention is very easy to remove and insert the grill shelf (1) according to this structural feature.

Then, a more detailed configuration of the present invention will be described with the drawings. In the present invention, the elongated fitting step 16 is formed at the first end of the upper plate 15, which forms the upper plate opening interval 12 of the body 10 of the oven 100, and also at the end of the cover frame portion 40. When the cover frame 40 covers the upper plate opening interval 12 by forming a corresponding corresponding step 41, it can be coupled to overlap each other. That is, the stepped portion is formed at the first end of the upper plate 15 forming the upper plate opening interval 12 of the body.

The fitting step portion 16 allows the cover frame portion 40 to completely overlap with each other, so that the corresponding step 41 formed on the cover frame portion 40 overlaps each other to achieve a tightly sealed coupling. While providing a wider interview area, it is possible to determine how accurate the closed state of the door according to the structure of the stepped portion of each other, and to induce a more secure fastening when closed.

In addition, the present invention forms a locking projection 45 and the locking groove 46 selectively in the fitting step portion 16 and the corresponding step 41 to perform a more stable coupling function. That is, the engaging projection 45 and the engaging groove 46 are formed in the fitting step 16 and the corresponding step 41.

In FIG. 4, although the locking groove 46 is formed in the fitting step portion 16 and the locking protrusion 45 is formed in the corresponding step portion 41, the upper plate 15 is reversely shown. A locking projection 45 may be formed on the fitting step 16, and a locking groove 46 may be formed on the corresponding step 41 of the “a” shaped cover frame part 40.

The engaging projection 45 and the engaging groove 46 are coupled to each other, and is an auxiliary means for preventing the door from being opened by unintentional vibration or movement. And it creates a feeling of click when opening and closing the door to induce the user to be aware of the closed state more easily and safely.

In addition, in the present invention, it is preferable to form a plurality of hook guide rails 60 so that the shelf 1 can be fitted to the side, for example, from the inner circumferential surface of the body 10 of the oven 100. To be inserted at the same time. That is, as shown in FIGS. 3 to 6, a plurality of locking guide rails 60 are formed on the left and right sides of the body 10 forming the oven. The hook guide rail 60 formed on the inner circumferential surface of the side plate allows the grill shelf 1 to be fitted, thereby allowing food to be cooked in multiple stages. This locking guide rail 60 shows an embodiment different from each of (a) and (b) of FIG. 4.

As a result, the locking guide rail 60 of the present invention has the same shape as that of (a) of FIG. 4 and the front and rear guide protrusions respectively formed by the linear guide rails 61 protruding in a horizontal shape. Forming, but the front is to form a square guide projection (63) protruding in a square, the rear is formed by the triangular triangular guide projection (64) in a larger number of narrow gap width to adjust the horizontal of the shelf (1) One of the form (b) of FIG. 4 is possible.

As shown in FIG. 4A, which is the former, a form of a long guide protrusion protruding from an inner circumferential surface of the left and right side plates is used as the guide rail 61. The shelf 1 may be kept in a horizontal state by inserting the grill shelf 1 into the first end of the guide protrusion.

By the way, although the guide rail 61 of this type is convenient to use in the installation place of the ground level, the height of the guide rail 61 or the rear support leg (A) of the oven 100 in a slightly inclined state is deformed. It is inconvenient to use in the condition. That is, when the shelf 1 is removed or inserted again or when the food is cooked, there is a risk that food may be directed to one side.

However, another embodiment of the present invention, such as (b) of Figure 4 can be utilized in all these installation sites. That is, a plurality of guide protrusions are formed on the side of the body 10, the square guide protrusions 63 are formed toward the opening of the door, and the triangular guide protrusions 64 are disposed on the square guide protrusions 63 to the rear side. Compared with the number of the horizontal adjustment to increase the adaptability.

First, the first end of the grill shelf (1) is sandwiched between the square guide projections 63, it can be inserted between the intervals that can maintain the horizontal of the triangular guide projections 64 located behind the insertion. The first end of the gap between the triangular guide projections is wider but the width becomes narrower toward the rear, so the position for supporting the grill shelf 1 is the triangular guide projections 64 of the narrow rear portion. will be.

The width of the utilization can be easily utilized in the oven 100 that can adjust a variety of heights as shown in FIG. That is, even when the height of the rear support leg (A) is different, it is possible to maintain the horizontal state of the shelf (1), if the shelf (1) does not maintain the horizontal, as shown in (b) of FIG. As such, it is also useful to mount in an inclined state so that the food inside can be seen more visually from the upright user. This feature is an advanced configuration that can provide room for more observing and judging the degree of cooking of the food cooked in the interior of the oven 100 by utilizing with the open top gap 12 of the present invention.

On the other hand, the door formed in the pre-oven of the present invention is a structure that puts a lot of effort to thoroughly block the smell that is generated from the contents of the inside during cooking or leaking the outside air into the oven. To this end, in the present invention, it is preferable to embed the magnet M in the fitting step 16 and the corresponding step 41 as shown in FIG. 7 to achieve a completed coupling of the door through magnetic force. The magnets M are embedded in the corresponding step 41 of the door frame 20 overlapping each other and the fitting step 16 of the upper plate 15 of the body 10. It is also possible to use a buried to interview with a polarity corresponding to each other, in the case that the door frame 20 or the upper plate 15 is made of a metal material, the magnet (M) is inserted into only one, and the other is the metal is attached to the magnetic force It is also possible to configure using.

In addition, the hinge 21 in the oven door structure of the present invention is preferably configured to generate a proper friction when the door frame 21 is formed by applying the hinge structure of the interference rotation using the friction force.

That is, in the present invention, unlike the conventional mini-oven structure, when the user opens the door, the door is opened to prevent the phenomenon of hitting the ground and the handle 22 at the bottom. To this end, the door of the present invention may also use a known stopper means for applying a friction force to the hinge 21 to open only as much as the user opens and stop further opening. The present invention is very free to rotate the door as shown in [Fig. 8] and [9], but if you want to rotate more than a certain angle to increase the frictional force to open the door even more than necessary force must be applied to the structure It is possible.

When the user opens the door of the mini-oven, and the door is opened from the top and rotated to the bottom, when a rotation angle is formed such that the handle 22 of the door frame 20 collides with the ground, friction force is applied to the rotation of the door. Many known techniques can be applied which are imparted so that they do not fall easily.

To this end, the present invention addresses an embodiment of a hinge structure that can be preferably used for this purpose. These configurations show an embodiment in which the frictional force is increased if it is to rotate more than a certain angle.

As shown in Figure 8 and Figure 9, when the hinge 21 'fastened to the door frame is rotated, the outer peripheral surface of the hinge 21' clip inserted into the body 10 side of the mini-oven 100 (10 ') is wrapped. The hinge 21 'has a circular cross section, but forms a flat portion 25 that cuts the outer peripheral surface of one side to prevent rotation. The clip 10 'corresponding thereto is also manufactured by bending the metal plate to have a cylindrical shape, and forms an extension part 12' and an incision part 11 extending to one side. And the plane stop portion 13 corresponding to the plane portion 25 is formed on one side.

Through this configuration, when the hinge 21 'is inserted into the clip 10' and rotates, when the flat portion 25 and the flat stop portion 13 meet, the friction is increased to stop the rotation. As such, the present invention can be easily used by applying the hinge using the friction force to the hinge of the mini-oven.

Lastly, the handle 22 of the mini oven carried out by the applicant of the present invention was manufactured by the method of aluminum extrusion. However, the handle of the present invention can be produced by the injection molding method as well as the iron sheet press.
