Description

  The present invention relates to a built-in heating cooker used by being incorporated in a sink.

  There exists a thing of patent document 1 as a built-in heating cooker used by incorporating in a sink. This heating cooker is installed such that the cooker body is inserted from the upper surface opening of the sink, and the front portion of the cooker body faces the front opening of the sink.

  Generally, after installation, it is necessary to fix the main body from the rear of the main body or a fixing bracket provided on the main body from the front surface of the main body so that the main body does not move. Therefore, in Patent Document 1, at a position deeper between the front surface of the main body of the cooker and the sink, the fixing bracket is pushed upward by screw tightening, and the sink is sandwiched between the frame of the main body, so that the load from the lateral direction of the main body is Even if it receives, it is trying to suppress deviation.

For example, in a conventional cooking device in which a heating coil for electromagnetic induction heating is mounted, a heating unit located on the upper surface is provided with a heating coil on the back side of the center in addition to the left and right heating coils. There is an inverter control unit that controls these heating means, and a cooling fan that cools the heating coil and the inverter control unit, and a roaster unit that mainly cooks fish and meat under the main body. Provided. Thereby, the main body weight of the product is about 20-30 kg.
When a product applies a load from the lateral direction, the frictional force is obtained by the following equation.
F = μN F: Friction force μ: Friction coefficient N: When the body weight of the vertical drag product is about 20 kg, the friction coefficient of the silicon-based packing applied to the back of the body frame is about 0.5. The frictional force is as follows.
F = 0.5 x 20kg = 10kg
By applying a tightening force with a fixing bracket to this, the product is prevented from shifting even if it receives a lateral load.

Japanese Unexamined Patent Publication No. 7-269883

  When embedding such a heavy heating cooker in a kitchen, it is necessary to work with two or more people to install the kitchen without damaging the kitchen. It is rare.

  However, when the product is reduced in weight, its frictional force is also reduced from the above formula. Therefore, in order to securely fix the product body, it is required that the fastening force by the fixing bracket is stably obtained.

  In the case of the fixing bracket as in Patent Document 1, since the mounting surface of the mounting bracket is substantially parallel to the back side of the main body, there is a problem that the product main body moves forward due to the tightening screw.

In order to solve the above-mentioned problem, the present invention is inserted from the upper surface opening of the sink, the front of the heating cooker faces the front opening of the sink, and the gap between the front opening and the front of the heating cooker a cooker equipped with a cover for covering the, between the front and the sink of the cooking device, the tightening screw fixing bracket is provided, push the fixing bracket upwards by tightening the clamping screw, The sink is sandwiched between a frame of the cooking device and the cooking device is fixed, and a screw receiving portion is provided so that the clamping screw does not fall down , and the screw receiving portion has a head of the clamping screw. It is characterized by supporting .

  According to the present invention, the tightening force by the tightening screw is reliably transmitted to the fixture, and can be reliably fixed to the sink.
