Cooker

The present invention relates to a heating cooker used in a general household kitchen, a commercial kitchen, etc., and in particular, constitutes the outline of the heating cooker and is provided around the top plate attached to the upper surface of the main body. It relates to a protective frame for protection.

In recent years, induction cooking devices having a heating unit on the upper surface of the main body have been widely used as cooking devices that do not use fire. In this induction heating cooker, a substantially rectangular top plate for placing a cooking container is provided on the upper surface of the main body. The heating unit is composed of a top plate and a heating coil provided below the top plate. In addition to this induction heating cooker, there is a cooker having a top plate on the upper surface, such as a halogen lamp, a radiant heater, and a gas cooker.

Also, in the top plate unit having the top plate as a constituent element, the edge of the top plate is covered with a protective frame over the entire circumference in order to avoid finger damage at the end.

The protective frame is composed of a frame that covers both side edges and the rear edge of the top plate, and a front plate that covers the front edge of the top plate, and an operation unit for operating the heating cooker is provided on the front plate. There is something.

However, the configuration in which the connection member is provided at the connection portion of the front frame (front plate) provided along the front of the top plate provided on the upper surface of the main body and the side frame provided along the side of the top plate is the number of parts. However, there was still room for improvement in terms of assembly.

Recently, there has also been proposed a capacitive touch control type operation unit provided on the front side of the top plate. In order to arrange the operation unit in such a configuration or to improve the appearance design. If the width of the upper part of the front frame is narrowed, the front frame and the side frame cannot be fixed to the top plate with sufficient strength, and there is a problem that the front frame is easily detached from the top plate.

In addition, according to the heating cooker described in Patent Document 1, when the contact piece has a variation in the size of the frame pieces, the frame pieces are distorted, or the accuracy of the connected state is reduced, a gap or There was a problem that a position shift occurred at the tip of the corner and the aesthetic appearance of the protective frame was lowered. In addition, the abutting part is exposed on the top surface of the top plate, and when cooking broth falls down on the corners of the protective frame during cooking, dirt such as the soup easily adheres between the abutting parts.

It is preferable to provide a back frame along the edge. In this case, the back frame is formed by bending a metal plate, and the lower end of the back frame is covered by the back frame upper surface covering the upper edge of the rear cover with the end abutting the surface of the rear cover, and the rear end of the back frame upper surface. A back frame rear surface formed by bending the back frame back surface, and a back frame bottom surface formed by folding the back frame rear surface to the under frame side and being locked to the back surface of the under frame, and bending the linear frame member A side frame that covers the surface edge on the side of the rear cover, the surface edge on the side of the top plate, and the back edge on the side of the under frame is integrally formed.

Further, a back frame that covers the rear surface edge behind the top plate and the rear surface edge behind the under frame may be provided, and the back frame may be formed integrally with the side frame by bending a linear frame member.

Also, the back frame may be divided into two and formed integrally with the side frame.

The rear edge of the upper surface of the front frame is bent and inclined so as to be lowered toward the upper surface side of the top plate, and the rear edge of the upper surface of the front frame is configured to contact the upper surface of the top plate.

Another embodiment of the present invention includes a top plate provided on the upper surface of the main body and formed in a substantially rectangular shape, a front frame disposed along the front surface of the top plate and formed by bending a metal plate, and along a side surface of the top plate. And a side frame formed by bending a metal plate, and the front frame has a front frame upper surface that is formed with an inclined portion that descends rearward to cover the upper edge of the top plate. A front frame front surface formed by bending downward at the front end of the front frame upper surface, a front frame front lower surface formed by bending inward at the lower end of the front frame front surface, and a side edge of the front frame upper surface Folded downward at the side of the front frame and folded inward at the lower end of the side of the front frame The side frame constitutes an insertion portion that is inserted inside the front frame, and the insertion portion is below the upper surface of the front frame and above the lower end of the inclined portion. A locking piece is formed to prevent the insertion portion from coming off the front frame by projecting in the longitudinal direction of the upper surface of the front frame and coming into contact with the inclined portion. The side frame is formed by bending a metal plate, and by configuring an insertion part in which the vicinity of the front end is inserted inside the front frame, there is no need to provide a connecting part with the front frame as a separate member. Is simplified.

The side frame is disposed below the upper surface of the front frame and above the lower end of the inclined portion at the insertion portion, protrudes in the longitudinal direction of the upper surface of the front frame, and comes into contact with the inclined portion so that the insertion portion comes out of the front frame. By forming the engagement piece to prevent this, when the insertion part of the side frame is inserted inside the front frame, the connection configuration between the front frame and the side frame is simplified with a simple structure, and its robustness is improved. Can be significantly increased. In addition, since the space occupied by the connecting portion between the front frame and the side frame can be reduced, the front and rear widths of the front frame upper surface can be reduced, and the design can be improved.

The side frame has a side frame upper surface that covers the upper edge of the top plate and a side surface of the side frame that is formed by bending the upper surface of the side frame downward, and has a belt-like convex portion that protrudes outward. The portion is deformed and formed at a position adjacent to the insertion portion. With this configuration, when the insertion part of the side frame is inserted inside the front frame, the band-shaped convex part that protrudes toward the outside is arranged adjacent to the end part of the front frame, so the side frame is inserted into the front frame. In addition to serving as a stopper, the cut surface at the end of the front frame is prevented from hitting the finger and edge protection is provided to prevent cuts.

Furthermore, the side frame is formed by bending the top side of the top surface of the top plate, side surfaces of the side frame formed by bending the top surface of the side frame downward, and side frames formed by folding the bottom side of the side surface of the side frame inward. A lower surface of the side frame at the insertion portion. In this configuration, when the side frame is inserted into the front frame, the lower end of the side frame side surface can be inserted inside while sliding with the lower end of the side of the front frame abutting against the end of the front frame side lower surface or the front frame side lower surface. it can. That is, the lower end of the side surface of the side frame is guided to the lower surface of the side of the front frame at the time of insertion, and the assembling work can be facilitated.

In the insertion part, if the lower corner part of the side frame side edge is deleted and a guide part with a slope rising from the rear to the front is provided at the lower end part of the side frame side, the insertion part of the side frame is moved to the front. When the guide is inserted into the frame, it slides in contact with the lower side surface of the front frame so that the locking piece moves under the lower end of the inclined part on the upper surface of the front frame so as to pass diagonally upward. Thus, since the inclined portion and the locking piece can be made difficult to interfere during insertion, the insertion operation is facilitated.

In addition, when the front frame has a notch at the side end portion of the inclined portion, and the upper surface portion that is a part of the convex portion of the side frame is disposed in the notch, the movement of the third frame to the inside and the front is performed. The front frame upper surface and the convex portion that form the notch are limited, and the rearward movement of the side frame is limited by the locking piece and the inclined portion of the front frame, so that the connection of the front frame can be stabilized.

Further, when the sloped portion formed in the belt shape and descending toward the front frame is formed on the locking piece of the side frame, the sloped portion provided on the locking piece serves as a guide, and the insertion portion of the side frame is placed on the upper surface of the front frame. It can make it easy to pass the lower end of an inclined part.

In addition, an underframe is formed of a metal plate and supports the top plate below the top plate. The lower end of the inclined portion of the front frame is in contact with the top surface of the top plate. The front frame is locked to the under frame by the protrusions provided so that the upper surface of the lower surface is in contact with and protrudes upward from the front frame front lower surface, and is fitted into the locking holes provided in the under frame. A front frame having a narrow width in the front-rear direction when viewed from above can be easily attached along the front edge of the top plate.

The underframe is made of metal and can be easily drilled. The front frame can be easily provided with protrusions on the front lower surface of the front frame by using a thin stainless steel plate (eg, 0.3 mm thick). The top plate is placed on and fixed to the front frame with an adhesive, etc., and inserted into the front frame with the side frame attached, so that the front frame can be easily fixed to the top plate and the under frame, and the front frame is made stronger by the top plate. It can be fixed. Therefore, the front frame can be thinned to improve the appearance, and the front frame can be easily assembled and the fixing strength can be stabilized.

In addition, the side frame includes a side frame upper surface that covers the top plate upper edge and is inclined downwardly toward the center side of the top plate, and a side surface of the side frame formed by bending the side frame upper surface downward. And a side frame lower surface formed by bending inwardly at the lower end portion of the side frame side surface, the lower end of the inclined portion of the side frame is in contact with the upper surface of the top plate, and the side frame lower surface on the side edge of the lower surface of the under frame When the side frame is locked to the under frame by inserting a protrusion provided so as to protrude upward from the bottom surface of the side frame into a locking hole provided in the under frame, the front frame and Similarly, the width of the upper surface of the side frame is narrowed to improve the appearance and the side frame Improving the fixing strength of neutrality can be stabilized.

According to the present invention, it is possible to eliminate a joint member formed as a separate member at the connecting portion between the front frame and the side frame constituting the protective frame, and the number of parts is reduced, and assembly is facilitated. Further, since the inner edge of the protective frame can be crossed at a substantially right angle at the front corner of the top plate, the appearance is not impaired. Further, the rear end of the front frame is disposed along the vicinity of the belt-shaped convex portions formed on the upper surface of the side frame and the side surface of the side frame, and the end of the side frame is covered with the edge of the front frame. Therefore, even if the hand touches the ends of the front frame and the side frame, no injury will occur.

Also, the side frame insertion part is inserted into the front frame, and the front frame and the side frame are mechanically fixed to each other by the locking piece and the inclined part of the front frame. In addition, the assemblability is improved.

A front frame side lower surface 22f which is a portion bent to the 13th side is formed, and is formed in a substantially bag shape as a whole. A plurality of mounting holes 24 and protrusions 25 are formed in the front frame front lower surface 22e. Further, the front frame front lower surface 22e has a substantially trapezoidal cover portion 26 protruding inward of the top plate unit 1 as shown in FIGS. 4 and 6 in the vicinity of the side end portion. .

The front frame side lower surface 22f and the front frame front lower surface 22e formed by being bent toward the top plate 11 at the lower end of the front frame side surface 22d are formed in substantially the same plane, and in the vicinity of the corner 19 of the protective frame 12 Adjacent with. Further, a cover portion 26 that protrudes to the inside of the top plate 11 is formed at an end portion of the front lower surface 22e of the front frame. In the present embodiment, the cover portion 26 is formed in the vicinity of both end portions of the front frame front lower surface 22e, and is formed in the vicinity of the end portion of the front frame side lower surface 22f. That is, the width of the front frame side lower surface 22f may be larger than the width of the front frame front lower surface 22e. Further, the shape of the cover 26 is not limited to that shown in FIG. 11, and the cover 26 protrudes inward so as to cover the back surface in the vicinity of the front corner 19 of the protective frame 12, and the front frame front lower surface 22 e and the side of the front frame As long as the portions where the lower surfaces 22f are adjacent to each other can be enlarged as compared with the case where the cover portion 26 is not provided, any shape may be used.

Further, as shown in FIGS. 3 and 4, the outer surface of the side frame 21b has an outer surface near the front end 21i of the side frame 21b on the outer surface of the side frame 21b. Are provided along the rear end portions 22 h and 22 i of the front frame 22. The convex portions 29 are formed in the vicinity of the front end portions 21i of the left and right side frames 21b along the respective outer surfaces. The convex portion 29 is formed by deforming the cross-sectional shape into a shape such as a part of a substantially ellipse or a part of a substantially rectangular shape, and the protrusion amount (the height of the bulge) of the convex part 29 is the front to be fitted. The thickness is preferably equal to or greater than the thickness constituting the frame 22. Note that the protruding amount of the convex portion 29 may be determined according to the thickness of the front frame 22 and the degree of backlash that is a clearance for fitting the front frame 22 and the frame 21 together.

Further, as shown in FIGS. 7 and 8, the front frame 22 has a substantially U-shaped cross section and is attached along the front edge of the top plate 11. At this time, the end portion 21i of the side frame 21b is inserted inside the front frame side surface 22d and the front frame upper surface 22a, and the rear end portion 22h of the front frame side surface 22d and the front frame upper surface 22a is protruded from the side frame 21b. It contacts or is adjacent to the portion 29 (see FIGS. 3 and 4). As a result, the front frame 22 covers the end 21i (edge) of the side frame 21b.

On the other hand, the rear end portions (edges) 22i and 22h of the front frame side surface 22d and the front frame upper surface 22a are in contact with or adjacent to the convex portions 29 formed along the outer surface of the frame 21. Thereby, since the convex part 29 is protruded and formed in the state without a sharp edge like a cut surface from the surface of the side frame upper surface 21e and the side frame side surface 21d as mentioned above, a chef is the side frame 21b. Injuries can be prevented at the front end portion 21i, the front frame side surface 22b, and the rear end portions 22i and 22h (edges) of the front frame upper surface 22a. The height of the protruding portion of the convex portion 29 can be appropriately set to a height that does not hurt the finger at the edge of the end portion of the front frame 22, for example.

Moreover, since the convex part 29 is integrally formed of the same material as the side frame 21 around the convex part 29, the convex part 29 is not conspicuous and is excellent in aesthetics. Further, since the side frame 21b is inserted into the linear front frame 22, as shown in FIG. 1 or 2, the corners on the cook side are substantially perpendicular at the portion where the top plate 11 is exposed. It is made up of aesthetics.

Further, as described above, a plurality of mounting holes 24 and protrusions 25 are formed in the front frame front lower surface 22e. As a result, the protrusion 25 formed on the front frame 22 is fitted into the hole formed in the under frame 13 in the same manner as the protrusion 23 formed on the frame 21 described above, thereby changing the front frame 22 into the under frame. Lock. Further, the front frame 22 is fixed by, for example, passing screws through the attachment holes 24 and screwing them into the under frame 13. As a result, it is possible to prevent the protective frame 12 composed of the frame 21 and the front frame 22 from being detached from the under frame 13 due to the locking by the protrusion 23 due to distortion or twisting.

Also, as shown in FIG. 10, when the main body case 2C is dropped into the substantially rectangular opening of the cabinet 1E and incorporated, the back surface of the protective frame 12 attached to the flange portion 2Cb of the main body case 2C is the cabinet.

Further fixed. When the sealing material 32 is fixed to the back surface of the front frame front lower surface 22e, as described above, the side edge of the front frame front lower surface 22e has a cover portion 26 that is partially traveled inward. Therefore, the sealing material 32 provided on the front frame front lower surface and the front frame side lower surface is not bent because it is provided between the protective frame 12 and the cabinet, particularly on the back side of the corner 19 in front of the protective frame 12. Since it is pressed against the cabinet by the top plate unit 1, the sealing effect by the sealing material 32 can be exhibited stably.

As shown in FIG. 8, the rear edge 30 of the front frame upper surface 22a, which is a portion constituting the upper surface of the front frame 22, is further on the top plate 11 side except for the portion into which the edge of the frame 21 is inserted. It is bent so as to descend and incline toward the end, and the end part comes into contact with the surface of the top plate 11 (the surface on which the cooking container is placed). Thereby, the gap formed between the top plate 11 and the front frame upper surface 22a can be closed. As a result, dust or the like can be prevented from entering the formed gap.

As described above, the protective frame 12 omits a joint member formed as a separate member at the connection portion between the side frame 21b and the front frame 22, and reduces the number of parts constituting the protective frame 12 to facilitate assembly. . Further, the rear end portions 22i and 22h of the front frame 22 are disposed in the vicinity of the convex portions 29 formed on the upper surface and the side surface of the side frame 21b, and the front end portion 21i of the side frame 21b covers the front frame 22. This prevents the cook from touching the end portion of the front frame 22 or the end portion 21i of the side frame 21b to prevent injury. Further, since the straight end portions inside the front frame 22 and the side frame 21b constituting the protective frame 12 are orthogonal to form a corner portion, the exposed corner portion of the top plate 11 bordered by the protective frame 12 is formed. It can be a substantially right angle. Thereby, the beauty of the top plate 11 can be improved.

Next, the protective lids 15a and 15b placed on the top plate unit 1 will be described with reference to FIG. 1, FIG. 2, FIG. 12, FIG.
