Description

  The present invention relates to a heating cooker used in general households and the like.

  In general, this type of cooking device is often made of stainless steel, enameled or fluorinated on the inside of the cooking cabinet. When cooking, the saucer is put in and out.If the inner surface of the cooking cabinet is made of stainless steel or enameled, the friction against the surface of the saucer is large until the oil generated during cooking becomes familiar with the inner surface of the cooking cabinet. There was a sense of incongruity such as rattling and bad slipping. On the other hand, in the case of fluorinated products, the friction is so small that the saucer slides well even if the oil generated during cooking does not blend into the cooking chamber inner surface, but the surface is damaged when worn because the fluorine itself is a soft material. It was easy to cause corrosion of the iron plate material forming the cooking chamber.

  In order to solve the above-mentioned scratches, a conventional cooking device is provided with a spacer made of a material having a high melting point and a high wear resistance on a part of the inner surface of the cooking chamber abutting on the saucer. (For example, refer to Patent Document 1).

The conventional cooking device has a high melting point and high wear resistance when the tray slides on the bottom of the cooking cabinet and takes it out of the cooking cabinet, even if the cooking cabinet is fluorinated. Since a spacer made of, for example, stainless steel is provided, the inner surface of the cooking cabinet can be prevented from being damaged and corrosion can be prevented.
Japanese Patent No. 2953871

  However, in the conventional cooking device, the portion that comes into contact with the saucer is composed of a spacer made of a substance having a high melting point and high wear resistance, and a material having a large friction coefficient with respect to the saucer is used as a spacer material. Even if the inner surface of the cooking cabinet was processed with fluorine, the slidability of the saucer deteriorated. Further, since the spacer is provided, there is an impact when the bottom end of the tray rides on the spacer when the tray is pulled out.

  The present invention solves the above-described conventional problems, and provides a cooking device that improves the slidability of the saucer in the cooking device, rattling when the tray is put in and out, and that does not feel uncomfortable such as poor sliding. The purpose is that.

  In order to solve the above-described conventional problems, the cooking device of the present invention has a part of the inner surface of the cooking chamber that abuts on the surface of the tray when the tray slides and has a coefficient of friction with respect to the surface of the tray. A spacer smaller than the height of the spacer is arranged on the inner surface of the cooking chamber near the spacer.

  This spacer reduces friction with the saucer and improves the slidability of the saucer.In addition, even if the spacer is worn out due to long-term use, a protrusion lower than the height of the spacer is placed near the spacer. Since the tray can be supported by the protrusions that the oil has been familiar with, the slidability of the tray is not impaired.

  The heating cooker of the present invention can improve the slidability of the saucer in the heating cooker, and can provide a heating cooker that does not rattle when the saucer is put in and out and that does not feel uncomfortable, such as poor sliding. .

It is capable of providing heating cooker not.

  In the second invention, in particular, the spacer of the first invention is provided in the vicinity of the opening on the bottom surface of the cooking chamber, and the protrusion has an inclined surface that becomes higher toward the opening and is opposite to the opening of the spacer. Because of the configuration located on the side, when the stored tray is pulled out, the bottom end of the tray can ride on the spacer, so the impact at the moment when the bottom end of the tray climbs on the spacer can be mitigated by the inclined surface formed on the projection. Instantaneous slidability can be improved, and a cooking device with better sliding of the tray can be provided.

  The third aspect of the invention is particularly characterized in that the spacer of the first or second aspect of the invention has a substantially arc cross-sectional shape with the vicinity of the contact portion with the saucer as a vertex in the sliding direction of the saucer. The impact at the moment when the bottom end of the saucer rides on the spacer when the tray is pulled out can be mitigated by the substantially arc-shaped spacer surface, so that the slidability at the moment when the tray is pulled out can be further improved. It is possible to provide a cooking device with good sliding.

  In the fourth aspect of the invention, the spacer of the first to third aspects of the invention is made of a fluororesin, so that the friction coefficient of the spacer surface with respect to the saucer can be greatly reduced, and the slidability of the saucer can be further improved. Is.

  In the fifth aspect of the invention, the spacer material of the fourth aspect of the invention is made of a fluororesin filled with graphite, so that the wear resistance of the spacer itself is improved, and the slidability of the tray even when used for a long period of time. It is possible to provide a heating cooker that can sufficiently maintain the temperature.
