Description

  The present invention relates to a cooking device having a top surface covered with a top plate.

  2. Description of the Related Art Conventionally, there has been proposed an apparatus in which a top surface of a box-shaped main body of a cooking device having a built-in heating source such as an electric heater or an electromagnetic induction heater is covered with a flat glass top plate (for example, Patent Document 1).

  The top plate is made of a material that has heat resistance and a predetermined strength, such as crystallized glass, but when a hard object such as a pan collides with the outer peripheral end face, which is a place that is relatively weak to impact force. There is a possibility of cracking. Therefore, there has been proposed a technique in which the lower surface of the frame is bonded to the upper surface of the top plate so that the outer peripheral end surface of the top plate is usually covered with a metal frame from the outside (for example, Patent Document 2).

  However, in the conventional cooking device, the top plate is placed on the upper part of the metal main body frame and fixed with an adhesive, so that the top plate is not formed with the expected dimensional accuracy. There was a problem that the position of the outer peripheral end face of the frame shifted, the frame hit the top plate, and the frame hit the upper outer periphery of the main body frame. In addition, since the frame is bonded to the top surface of the top plate, part of the adhesive may protrude from the sides of the frame during the manufacturing process. Since the agent remains, which is a problem in terms of design, there is a problem that productivity is poor, for example, an operation for removing the adhesive is required.

  The present invention has been made to solve the above-described problems. A protective member that covers the outer peripheral edge of the top plate from the lower surface to the end surface, and the protective member and the top plate are placed on the upper surface. And a holding member formed by fixing both of them with an adhesive member.

That is, the present invention includes a main body that constitutes the outer shell of the cooker, a flat top plate that is fixed so as to cover the upper surface of the main body, a protective member that covers from the bottom of the top plate to the outer peripheral end surface, and the protection A member and a top plate are placed on the upper surface, and both of them are fixed by an adhesive member and a holding member fixed to the main body . The protective member faces the end surface of the top plate with a small gap. A protective part, a base formed continuously to the protective part, a presser part rising from the base part toward the top plate by a predetermined dimension, and a fixed end part on the opposite side of the base part across the presser part, Is formed integrally, and the fixed end portion is overlaid on the holding member, and the holding portion is simultaneously held by an adhesive filled in a space between the pressing portion, the fixed end portion, and the top plate. The member is also bonded .

  In the heating cooker according to the present invention, even when the dimensional accuracy of the top plate changes slightly, the mutual adhesion position of the holding member and the protection member is changed to position the protection member at a predetermined position outside the outer peripheral end surface of the top plate. Can do. In addition, since it is not necessary to bond a protective member on the top surface of the top plate, no adhesive remains on the top surface of the top plate, eliminating the need to remove the adhesive on the top surface of the top plate, and improving productivity. It becomes.

  At both left and right ends of the holding member 3, there are formed fixing portions 3T that are bent downward and extend laterally by a dimension (Y) that is equal to or slightly larger than the rising dimension (X) of the base 5Q of the protective member. Has been. 3S is the bent portion.

  In FIG. 2, a space S <b> 3 that is filled with the adhesive 11 is formed between the lower surfaces of the left and right ends of the top plate 4, the left and right ends of the holding member 3, and the upper surface of the protection member 5. A continuous space S2 is formed below the gap S1 between the lower surface of the left and right ends of the top plate 4 and the upper surface of the protective member 5.

  In FIG. 1, TP is a top plate unit including the holding member 3, the top plate 4, the protection members 5 </ b> A and 5 </ b> B, the front frame 6, the rear frame 7, and the cover 8.

  In the cooking device having the above-described configuration, if a plurality of induction heating coils serving as heating sources for electromagnetic induction heating are energized, the metal pan placed on the top plate 4 above the energized heating coil The heat generated by the principle of induction heating is generated by the lines of magnetic force transmitted through the top plate 4 from the heating coil, and the food to be cooked contained in the pot is cooked.

  Next, a method for assembling the top unit of the cooking device will be described below. First, the top plate 4 shown in FIG. 2 is turned upside down, and protective members 5A and 5B are placed on the lower surface (back surface). This can be better understood by looking at FIG. 2 upside down.

  Next, a heat-resistant adhesive 11 such as silicon is applied to the portion that becomes the space S3. Then, while the adhesive 11 is not cured, the holding member 3 is put on the upper surface (the lower surface in FIG. 2) of the top plate 4 from above. Then, the lower surface (upper surface in FIG. 2) of the holding member 3 is in close contact with the upper surface (lower surface in FIG. 2) of the top plate 4.

  In a state where the top plate 4, the holding member 3, and the protective members 5A and 5B are fixed with the adhesive 11, the lower surface of the top plate contacts the pressing portion 5R of the protective members 5A and 5B or has a slight gap. Hold and meet. This is because, as described above, the fixing portion 3T that is bent downward and extends sideways by a dimension (Y) that is equal to or slightly larger than the rising dimension (X) of the base portion 5Q of the protective member is formed. It is. In addition, considering that the edge portion of the end portion (right end portion in FIG. 2) of the fixing portion 3T does not protrude downward from the base portion 5Q (the thickness of the holding member 3 and the thickness of the protective members 5A and 5B are Ideally, the dimensions should satisfy the relationship X ≧ Y. By doing so, the lower surface of the fixing portion 3T and the lower surface of the base portion 5Q are aligned on the same plane (when X = Y), or the lower surface of the base portion 5Q slightly protrudes from the lower surface of the fixing portion 3T (X> Y Case). It should be noted that a jig or the like is used to ensure mutual alignment in the fixing work of the three members of the top plate 4, the holding member 3, and the protective members 5A and 5B.

  The top plate 4, the holding member 3, and the protection members 5 </ b> A and 5 </ b> B integrally fixed as described above are aligned with the upper surface opening 2 portion of the main body 1, and the rear frame 7 is fixed with the screw 10 to the main body 1. Fixed. When the front frame 6 is also fixed to the holding member 3 with screws 9, the front frame 6 and the rear frame 7 are fixed to the main body 1 so as to wrap around the front end portion and the rear end portion of the top plate 4, respectively. Note that the front end portion of the holding member 3 may be coupled to the main body 1 at the same time with a screw 9, or may be coupled to the main body 1 with another coupling means.

FIG. 4 is an explanatory view showing a state where the top plate 4, the holding member 3, and the protective members 5 </ b> A and 5 </ b> B are fixed with the adhesive 11. In general, there is a large difference in dimensional tolerance between a glass material such as a top plate and a metal material such as the holding member 3 and the protection members 5A and 5B. Moreover, the top plate 4 receives heat from an object to be heated such as a pan heated to a high temperature by a heating source, and becomes 300 degrees or more. When a radiation type electric heater called a radiant heater is provided below the top plate 4, the lower surface of the top plate 4 is directly heated by the heat of the heater, and the temperature may be as high as 400 degrees. Therefore, there is expansion due to temperature rise, and when the protective members 5A and 5B are integrated, the minute gap S1 between the protective portions 5P of the protective members 5A and 5B and the left and right end surfaces of the top plate 4 is large. Variations occur.

  Therefore, since it is necessary to assemble in consideration of the above-described variations in the manufacturing process, it is inevitably impossible to achieve a highly accurate configuration, and a large gap may be formed in the left and right end surfaces of the top plate 4. Such a gap also causes the ingress of liquid generated by cooking and the intrusion / accumulation of dust, which has been a cause of deteriorating aesthetics in long-term use.

  On the other hand, in the first embodiment of the present invention, the case where the horizontal width dimension of the top plate 4 is the predetermined width (A) and the dimension (A + α) slightly larger than the predetermined width (A). In any case, accurate assembly is possible.

  That is, when the horizontal width dimension of the top plate 4 is a dimension (A + α) that is slightly larger than the predetermined width (A), the protective members 5A and 5B are independent on the left and right sides. What is necessary is just to adjust the position which fixes 5A and 5B. And what is necessary is just to make it the fine clearance gap S1 between the protection part 5P and the end surface of the top plate 4 fit in a predetermined dimension range.

  According to the first embodiment of the present invention, even when the dimensional accuracy of the top plate 4 is slightly changed, the mutual adhesion position of the holding member 3 and the protection members 5A and 5B is changed to be predetermined outside the outer peripheral end surface of the top plate 4. The protection portions 5P of the protection members 5A and 5B can be positioned at the positions. Further, since it is not necessary to bond the protective members 5A and 5B on the top surface of the top plate 4, no adhesive or the like remains on the top surface of the top plate 4, and no work for removing the adhesive on the top surface of the top plate 4 is required. It becomes possible to improve the nature.

Next, a second embodiment of the present invention will be described. Unless otherwise specified, the configuration of the first embodiment described above is assumed, and the same or corresponding parts are denoted by the same reference numerals and description thereof is omitted.
FIG. 3 is a longitudinal sectional view showing the second embodiment. Reference numeral 12 denotes a cushioning material in which protective members 5A and 5B are fixed to the lower surface of the top plate 4. Adhesive surfaces are formed on both surfaces to form a double-sided tape. ing.

  In the second embodiment, when the cushioning material 12 is pasted on the top plate 4 in the process of assembling, and the protective members 5A and 5B are placed thereon, the protective members 5A and 5B and the top plate 4 are temporarily fixed. Can be in a state.

  Therefore, according to the second embodiment of the present invention, even when the adhesive 11 is applied and the holding member 3 is fixed, the positions of the protective members 5A and 5B can be prevented from being inadvertently shifted and workability is improved. . In addition, since the end surface of the top plate 4 is always protected by the protective members 5A and 5B, even when an object accidentally collides with the end surface of the top plate 4 during work, the end surface of the top plate 4 is prevented from being damaged. This also improves the workability.

  FIG. 5 is a longitudinal sectional view showing the third embodiment of the present invention. Note that the configuration of the first embodiment described above is a premise unless explicitly stated otherwise. The same reference numerals are given and description thereof is omitted. The third embodiment shown in FIG. 5 is characterized in that the protective member 5A-side end portion of the protective member 5A, 5B is bent 180 degrees outward and brought into close contact with the back surface.

  According to the third embodiment of the present invention, the protective member 5A side end portion of the protective member 5A, 5B is bent 180 degrees outward and brought into close contact with the back surface, so that the end portion of the protective portion 5P itself It becomes round and can improve the safety of the place which the user of the cooker and the assembly worker touched.
