Description

The present invention relates to an oven comprising a door.
The assembly of oven doors onto the body is a critical issue. Because, when the door is not fully closed, heat exchange is caused in the cooking chamber and this causes energy loss. The most important reason for the door not to be fully closed onto the body is that the hinge group, forming the only connection between the door and the body, cannot be fixed onto the body in a secured and proper manner.
In the state of the art European Patent Application No EP155486 , the vertical profiles and the bearing are a single piece.
In the state of the art German Patent Application No DE102005037020 , the hinge is fixed by being inserted into the vertical profile.
In the state of the art European Patent Application No EP1918645 , the hinge is fixed by being inserted into the vertical profile. Further relevant prior art is mentioned in the document EP0900986 .
The aim of the present invention is the realization of an oven having a door which is assembled to the body in a correct and safe manner.
The oven realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, has a brace comprising a locking means which is located at the brace surface that is adjacent to the inner wall of the vertical profile, and which is seated into the opening on the vertical profile inner wall by moving on the horizontal plane when the brace is inserted into the vertical profile. Thus, the brace can be removably mounted to the vertical profile. The brace, which is assembled onto the door by being inserted into the vertical profile, bears the hinge arm to the door. Thus, the hinge arm, which is shorter than the hinge body, is provided to be mounted to the door in a more secured manner.
The locking means provides the brace to be locked inside the vertical profile and thus, prevents the brace from moving back and forth. The brace, which is inserted into the vertical profile, can only be dismounted from the vertical profile by releasing the locking means from the housing by stretching it again.
The cross-section of the guiding means becomes narrow towards the vertical profile center in the entering direction of the brace into the vertical profile. Thus, the brace is provided to be inserted into the vertical profile more easily.
On the locking means, the brace comprises at least one detent means that forms a protrusion, the cross-section of which becomes narrow in the entering direction of the brace into the vertical profile. Thus, while the brace is inserted into the vertical profile, the locking means stretches as a result of the detent means, which contacts the walls of the vertical profile, slidingly moving inside the vertical profile, and when the detent means corresponds to the opening, the locking means is seated into the opening by returning to its initial position.
The stretching of the locking means is provided by means of the cut-outs surrounding the locking means.
When the locking means is seated in the housing and the support means bears against the wall edges of the vertical profile, one edge of the vertical profile is also seated into the slit and thus, the brace is prevented from moving further forward inside the vertical profile.
In an embodiment of the present invention, the brace comprises a bearing means which is located on the support means and which partially surrounds the corner of the inner panel, disposed onto the casing, from above and from side, and wherein the inner panel is borne. Thus, the inner panel is pressed from its both sides by the casing.
By means of the present invention, the assembly of the door to the body can be performed in a safer and faster manner.

The oven (1) of the present invention comprises a cooking chamber (2) wherein items desired to be cooked are placed, a door (3) which allows access to the cooking chamber (2), an outer panel (4) which is located on the door (3) and which forms the door (3) surface that contacts the outer environment, an inner panel (5) which forms the door (3) surface that contacts the cooking chamber (2), a casing (6) which is located between the outer panel (4) and the inner panel (5), and on one side of which the outer panel (4) and on the other side of which the inner panel (5) are fixed such that they will be parallel to each other, and which has quadrangular and hollow vertical profiles (7) forming the side edges of the door (3) and a quadrangular and hollow horizontal profile (8) connecting the vertical profiles (7) to each other, and which is formed by joining the profiles (7 and 8) together in an upside-down "U"-shape, and two hinges (10) that have a hinge body (11) and a hinge arm (12), one end of which is fixed to the hinge body (11) and the other end to the door (8), and that provide the door (8) to be opened and closed as a result of the movement of the hinge body (11) and the hinge arm (12) with respect to each other (Figure 1, Figure 2 and Figure 3).
The oven (1), furthermore, comprises a brace (13) which is mounted to the open ends of the vertical profiles (7) and which has a hinge housing (24) wherein the hinge arm (12) is seated. The brace (13), which is assembled onto the door (3) by being inserted into the vertical profile (7), provides the hinge arm (12) to be borne to the door (3).
The vertical profile (7) comprises an opening (9) which is located on the inner wall (IW) that is at the vertical profile (7) side facing the space between the panels (4 and 5). The brace (13) has a locking means (16) which is located on the brace (13) surface that is adjacent to the inner wall (IW) and which is seated into the opening (9) by moving on the horizontal plane when the brace (13) is inserted into the vertical profile (7) (Figure 4, Figure 5 and Figure 13, Figure 14).
By means of the locking means (16), the brace (13), which is preferably produced from plastic material, is mounted to the vertical profile (7), which is preferably produced from metal material, hence to the casing (6) in an easily removable manner.
The locking means (16) provides the brace (13) to enter into the vertical profile (7) by stretching in the horizontal direction and enters into the housing by returning to its initial position when it corresponds to the housing while moving forward inside the vertical profile (7) and thus, the locking means (16) provides the brace (13) to be locked to the vertical profile (7). The locking means (16) provides the brace (13) to be locked inside the vertical profile (7) and thus, prevents the brace (13) from moving back and forth inside the vertical profile (7). The brace (13), which is inserted into the vertical profile (7), can only be dismounted from the vertical profile (7) by providing the locking means (16) to be released from the housing by being stretched again.
The brace (13) comprises a guiding means (14) which is concentrical with the vertical profile (7) and which enters into the vertical profile (7), and whereon the locking means (16) is situated, and a support means (15) which remains outside the vertical profile (7) when the guiding means (14) enters into the vertical profile (7) since it has a wider cross-section than the cross-section of the vertical profile (7). In this embodiment of the present invention, the oven (1) comprises a hinge housing (24) which is located on the support means (15) and wherein the hinge arm (12) enters.
The assembly of the door (3) to the body is performed as follows: The brace (13) is inserted such that the guiding means (14) will completely enter into the vertical profile (7) (Figure 6). During this movement, the locking means (16) stretches in the horizontal direction and does not prevent the movement of the guiding means (14) inside vertical profile (7). When the locking means (16) corresponds to the housing, it enters into the housing by returning to its initial position. In this situation, the support means (15), also, bears against the edges of the four walls of the vertical profile (7) (Figure 7). Then, the outer panel (4) and the inner panel (5) are fixed onto the casing (6) and finally the hinge arm (12), which extends from the body outwards as connected to the hinge body (11), is inserted into the hinge housing (24) on the brace (13) and thus, the assembly of the door (3) to the body is completed (Figure 8, Figure 9, Figure 10, Figure 11 and Figure 12).
The hinge (10) comprises one or more hooks (26) which provide the fixing onto the brace (13) when the hinge arm (12) is inserted into the hinge housing (24). In this embodiment of the present invention, the brace (13) comprises one or more hook housings (27) which are located on the support means (15), and wherein the hooks (26) on the hinge (10) are seated and locked when the hinge arm (12) is inserted into the brace (13). In another embodiment of the present invention, the guiding means (14) is quadrangular and hollow. The cross-section of the guiding means (14) becomes narrow towards the vertical profile (7) center in the entering direction of the brace (13) into the vertical profile (7). Thus, the brace (13) is provided to be inserted into the vertical profile (7) more easily.
In another embodiment of the present invention, the brace (13) comprises at least one detent means (17) which is located on the locking means (16) and the cross-section of which becomes narrow in the entering direction of the brace (13) into the vertical profile (7). Thus, while the brace (13) is inserted into the vertical profile (7), the locking means (16) stretches as a result of the detent means (17) slidably moving inside the vertical profile (7) by contacting the walls of the vertical profile (7), and when the detent means (17) corresponds to the opening (9), the locking means (16) is seated into the opening (9) by returning to its initial position.
In another embodiment of the present invention, the brace (13) comprises a cut-out (18) which surrounds the locking means (16) at least from its two sides. The stretching of the locking means (16) is provided by means of these cut-outs (18).
In another embodiment of the present invention, the brace (13) comprises at least one slide (29) which is located on each edge of the guiding means (14). While preferably one slide (29) is situated on the short edges, preferably two slides (29) are located on the long edges. By means of the slides (29), the brace (13) is provided to stand more rigidly in the vertical profile (7).
In another embodiment of the present invention, the brace (13) comprises a slit (19) which is located on the support means (15) and wherein the edge of the outer wall enters when the brace (13) is seated in the vertical profile (7). When the locking means (16) is seated in the housing and the support means (15) bears against the wall edges of the vertical profile (7), one edge of the vertical profile (7) is also seated into the slit (19) and thus, the brace (13) is prevented from moving further forward inside the vertical profile (7).
In another embodiment of the present invention, the brace (13) comprises a bearing means (20) which is located on the support means (15) and which partially surrounds the corner of the inner panel (5), disposed onto the casing (6), from above and from side, and wherein the inner panel (5) is borne. The bearing means (20) comprises a protrusion (21) which extends next to the inner panel (5) and a bracket (22), against which the lower edge of the inner panel (5) bears, both occurring when the inner panel (5) is disposed into the casing (6), and an arm (23), which presses the inner panel (5) by bending onto the inner panel (5) and by bending vertically to the bracket (22) on the end of the bracket (22). Thus, the inner panel (5) is pressed from its both sides by the casing (6) by means of the arm (23).
