Description

  The present invention relates to a built-in cooking device incorporated in a kitchen counter of a general household.

Traditionally, embedded heating cooker of this type, a configuration for mounting to a top surface of the kitchen counter to support the weight of the body shell, it is provided (for example, see Patent Document 1).

Figure 4 shows the traditional embedded heating cooker (the induction heating cooker). As shown in FIG. 4, the main body 40 of the induction heating cooker is covered with an outer shell 41 that supports the built-in components, and a top plate unit 42 is placed and fixed on the upper opening of the outer shell 41, and the upper opening of the outer shell 41 is fixed. The outer flange portion 43 projecting vertically along the wall is placed on the kitchen counter 44. Here, in the top plate unit 42, the top plate 45 is sandwiched between the under frame 46 and the top frame 47, and a predetermined portion is bonded and fixed, and a sealing agent 48 having elasticity at the lower surface fitting portion of the under frame 46 and the top frame 47 is provided. Is bonded and fixed to the entire periphery along the outer periphery of the under frame 46, and protrudes from the lower surface of the under frame 46. When the outer flange 43 is placed on the kitchen counter 44 at the time of installation, the sealant 48 of the top plate unit 42 is compressed by a predetermined size, and the lower surface of the top plate unit 42 is sealed against the top surface of the kitchen counter 44. It is configured to be placed on the top surface with a gap corresponding to the size of the agent 48 after compression.

  However, in the conventional configuration, the outer flange portion 43 is placed on the top surface of the kitchen counter 44 to support the weight of the main body 40 during installation, and the sealing agent 48 is compressed and pressed against the top surface of the kitchen counter 44. Because of the configuration, there is a gap between the underside of the under frame 46 and the top frame 47 and the top surface of the kitchen counter 44, and the gap can be seen from the exterior. Dust and cooking residue are easily contained, and the gap is conspicuous. However, there was a problem that anxiety was caused even if there was no actual problem with the intrusion of water or the like.

  In addition, in the conventional built-in induction heating cooker, the height when the top plate unit 42 is installed is configured to be about 10 mm, but the height is reduced to about a quarter in the present invention. Because of the configuration, there was a problem that if there was a gap in the appearance, it would be even more noticeable and would lack productability and design.

  The present invention solves the above-described conventional problems, and has a configuration in which the level difference between the cooking surface constituted by the glass top and the top surface of the kitchen counter is substantially the same, thereby improving usability and cleaning properties. The object is to provide a built-in heating cooker that is excellent and significantly enhances the total design of the system kitchen.

  In order to solve the above-mentioned conventional problems, the built-in heating cooker according to the present invention is configured so that the thickness dimension of the lower surface and the upper surface of the top plate unit 42 contacting the kitchen counter 44 in FIG. 4 can be significantly reduced. It is what. At the same time, the lower surface of the top plate unit 42 is configured to support the weight of the main body 40.

  As a result, the step between the top surface of the kitchen counter 44 and the top surface of the top plate unit 42 is significantly reduced.

  Further, when the lower surface of the top plate unit 42 contacts the kitchen counter 44 at the time of installation, the outer flange portion 43 has an appropriate gap with the counter opening step surface connected to the top surface of the kitchen counter 44, and the top plate unit 42 The lower surface floats from the top surface of the kitchen counter 44 so that there is no gap.

  Thereby, the top plate unit 42 has a structure for supporting the weight of the main body 40 and a back-up structure by the outer flange portion 43, and no gap is formed between the lower surface of the top plate unit 42 and the top surface of the kitchen counter 44. It will work to improve the merchantability and design.

  The built-in heating cooker according to the present invention can be configured so that the level difference between the cooking surface composed of the glass top and the top surface of the kitchen counter is substantially the same surface, and is excellent in usability and cleanability and system. It is possible to provide a built-in heating cooker that significantly improves the total design of the kitchen.

  1st invention is a built-in heating cooker provided with the main body which covers a built-in component with an outline, and the top plate unit which covers and fits the upper surface opening of the said main body, and comprises the cooking surface of a kitchen counter The top plate unit is composed of an under frame, a top plate placed on the under frame, and a decorative plate disposed so as to cover the entire outer periphery of the top plate. A folding portion that is bent and clamped along the flange portion surface of the underframe that protrudes outward from the outer peripheral edge of the top plate, and the bottom surface of the folding portion of the top plate unit is the top of the kitchen counter. In the configuration placed on the surface, the outer flange portion disposed on the four sides of the upper opening of the main body and the kitchen cowl A gap with the stepped surface of the kitchen is appropriately provided, the stepped surface of the kitchen counter abuts against the outer flange portion to push up the built-in heating cooker, and the lower surface of the folding portion of the top plate unit is the kitchen counter The top plate installed on the kitchen counter and the top surface look almost the same, making it easy to design and clean with no gaps. Can be provided.

  In the second invention, in particular, a hook portion is provided in front of the top plate unit of the first invention, the main body and the top plate unit are hooked and fixed with the hook portion, and the screw is fixed behind the top plate unit. In the configuration where the screw is fixed to the main body, a service shaft for repairing or replacing parts inside the main body is provided by arranging a support shaft that can adjust the length from the lower surface of the main body in the vicinity of the front of the lower surface of the main body. In the work, even if the top plate unit is removed from the main body, the front of the main body does not fall down due to the gap between the outer flange and the kitchen counter's stepped surface. The hook part of the top plate unit can be hooked on the main body and placed and fixed on the main body without any trouble. In addition, the rear of the top plate unit can be pulled up to the original position by tightening screws even if the main body falls by the gap.

  The third aspect of the invention is particularly suitable for service work for repairing or replacing parts inside the main body by arranging an arbitrary number of support shafts behind the lower surface of the main body of the second invention. Even if the plate unit is removed from the main unit, the entire main unit does not drop as much as the gap between the outer flange and the kitchen counter's stepped surface, and the installation position remains the same as before the service. The plate unit can be placed and fixed on the main body.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.
