Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings, which illustrate representative embodiments of the present invention and do not limit the present invention.

The utility model discloses a cooking utensil. The cooking appliance provided by the utility model can be an electric cooker, an electric pressure cooker, a food processor, a soybean milk maker, an electric stewpan or other electric heating appliances. Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in fig. 1, the cooking appliance 1 according to the present invention may be configured to include a pot body 10 and a lid body 20. The cooker body 10 has a cylindrical inner pot receiving portion (not shown) therein, and the inner pot (not shown) may be fixedly disposed at the inner pot receiving portion, or may be freely put into or taken out from the inner pot receiving portion, so as to facilitate cleaning of the inner pot. The upper surface of the inner pot has a circular opening for containing materials to be heated, such as rice, soup, etc., into the inner pot.

The lid 20 has a shape corresponding to the pot body 10 and can be opened and closed with respect to the pot body 10. When the lid body 20 is closed on the pot body 10, a cooking space (not shown) is formed between the lid body 20 and the inner pot.

Further, a heating means (not shown) for heating the inner pot is further provided in the pot body 10 below the inner pot. According to the invention, the heating device is constructed in the form of an electromagnetic heating device. In one example, the electromagnetic heating device may particularly be a coil disc. Correspondingly, the inner pot contains magnetic conduction heating material. When the coil disc is operated, the inner pot generates eddy currents in the pot wall of the inner pot in response to the alternating magnetic field of the coil disc. The vortex generates a large amount of heat to heat the wall of the pot, thereby heating the food or water in the inner pot.

As shown in fig. 1, in the present embodiment, a pot body 10 is configured to include a base 11 and a middle plate 12. Referring again to fig. 2, the base 11 includes a bottom wall 111 and a side wall 112 extending upward from an edge of the bottom wall 111. Thus, the base 11 forms an accommodation space to accommodate components of the inner pot, the electromagnetic heating device, and the like. It will be appreciated that the electromagnetic heating means is disposed above the bottom wall 111 and below the inner pan. The middle plate 12 is disposed above the base 11 to make the accommodating space of the base 11 relatively closed, and protect the components therein. The base 11 may be made of plastic. Thus, the base 11 may also be referred to as a plastic base 11. The middle plate 12 may be made of a plastic material or a metal material such as stainless steel as required.

In order to avoid the magnetic field leakage to the outside of cooking utensil 1 that electromagnetic heating device produced at the during operation, according to the utility model discloses a cooking utensil separates the magnetism and handles in electromagnetic heating device's position department, also promptly plastic base 11. Specifically, the interior of at least the portion of the plastic base 11 located below the electromagnetic heating device is filled with a magnetic shielding material. The magnetic shielding material may be aluminum fines or small particles that may be filled into the plastic during the manufacturing process of the plastic base 11 to form the plastic base 11.

In one example, the magnetic shielding material may be mixed with plastic particles according to a certain mixing relationship, and then the plastic base 11 may be formed by injection molding using the mixed particles. Alternatively, in another example, the bottom wall 111 and the side wall 112 of the plastic base 11 may be separately injection molded. Wherein only the bottom wall 111 is made of plastic particles mixed with the magnetic shielding material, and the side wall 112 may be made of only plastic particles. Therefore, the use of magnetism isolating materials at unnecessary positions can be avoided, and the cost is saved. The separately formed bottom wall 111 and side walls 112 may be welded together, such as by thermal or ultrasonic welding, to form the unitary structure of the plastic base 11.

Through the arrangement, the plastic base 11 has the magnetic isolation function, so that a metal magnetic isolation piece can be omitted, the number of parts is reduced, the production cost can be reduced, and the production and assembly efficiency is improved. In addition, the cooking utensil can avoid generating obvious abnormal sound due to vibration when in use, thereby improving the use experience of consumers.

As shown in fig. 2, it can be understood that the electromagnetic heating device is disposed above the bottom wall 111 of the plastic base 11. Preferably, the inner side surface of the bottom wall 111 may be partially recessed to form a recess 113 for accommodating the electromagnetic heating device, which may improve the fixing firmness of the electromagnetic heating device and facilitate the positioning of the electromagnetic heating device during assembly. The electromagnetic heating device is generally configured as a circular coil disk, and therefore, the recess 113 has a substantially circular shape conforming to the coil disk.

Preferably, the plastic base 11 is further provided with a drain hole 115 penetrating the bottom wall 111 on the bottom wall 111. The liquid entered inside the pot body 10 can be discharged to the outside through the drain hole 115. Therefore, it can be understood that the drain hole 115 is provided at the lowest position of the bottom wall 111. As shown in fig. 2, the drain hole 115 includes two spaced apart holes. Both located within the recess 113. Of course, additional drain holes may be provided at other positions of the bottom wall 111.

Generally, an electromagnetic heating device is disposed above the drain hole 115. In order to prevent the liquid discharge hole 115 from being clogged, it is preferable that a support rib 114 protruding upward is provided on the inner side surface of the bottom wall 111 around the liquid discharge hole 115. The support rib 114 can separate the components such as the electromagnetic heating device from the drain hole 115 in the up-down direction, thereby preventing clogging. Further preferably, the support ribs 114 may be provided at intervals in the circumferential direction of the drain hole 115 to form the slits 116. Therefore, even if the components of the electromagnetic heating device are completely attached to the upper edge of the support rib 114, the liquid can flow into the liquid discharge hole 115 through the gap 116 and the space between the upper edge of the support rib 114 and the liquid discharge hole 115 and be discharged, thereby avoiding the failure of the liquid discharge function.

Unless defined otherwise, technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Terms such as "disposed" and the like, as used herein, may refer to one element being directly attached to another element or one element being attached to another element through intervening elements. Features described herein in one embodiment may be applied to another embodiment, either alone or in combination with other features, unless the feature is otherwise inapplicable or otherwise stated in the other embodiment.

The present invention has been described in terms of the above embodiments, but it is to be understood that the above embodiments are for purposes of illustration and description only and are not intended to limit the invention to the described embodiments. It will be appreciated by those skilled in the art that many more modifications and variations are possible in light of the above teaching and are intended to be included within the scope of the invention.
