Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cooker such as an electric cooker on which a cooking pot is detachably mounted.

[0002]

[Prior art]

 In an electric cooker in which a cooking pot is detachably mounted, a shallow pot and a deep pot may be used depending on the type of cooking. In such a cooker, since the cooker body is configured to fit in a pan with a shallow bottom, when a pan with a deep bottom is placed, a wide gap will be created on the outer peripheral surface of the pan, and thermal efficiency will increase. descend. For this reason, it has been conventionally known to mount a ring-shaped member to close the gap on the outer peripheral surface of the pot.

That is, in the conventional electric cooker, as shown in FIG. 5, a heat-resistant synthetic resin guard 4 attached to a bottom plate 3 is provided around the heating device 2 of the cooker main body 1, and the guard 4 is placed above the guard 4. A guard ring 6 made of stainless steel has been detachably placed on the outside of the locking ribs 5 provided at several points on the edge.

In this case, when using a pan 7 with a deep bottom, as shown by the chain double-dashed line in FIG. 5, the guard ring 6 is placed on the guard 4 and then the pan 7 is placed on the heating device 2. Put. With this configuration, the guard ring 6 prevents the heat from escaping from the outer peripheral portion of the pan 7 having a deep bottom.

In the case of a pan 7'having a shallow bottom, the guard ring 6 is removed before use.

[0006]

[Problems to be solved by the device]

 By the way, the above guard ring 6 is merely engaged with the outer peripheral surface of the locking rib 5 of the guard 4 at the inner peripheral edge of the lower end thereof, and the locking rib 5 thereof has a brim 8'of the shallow pan 7 '. Since it is not so high in order to avoid interference with the guard ring 6, it has a drawback that it is easily disengaged from the locking rib 5 when an external force acts on the outer peripheral surface of the guard ring 6.

Further, in the electric cooker described above, the guard 4 of the cooker body 1 is made of heat-resistant synthetic resin, while the guard ring 6 is made of stainless steel, so that the difference in material and color Due to differences and the like, there was a problem in that the appearance of the cooker body 1 lacked the sense of unity between the guard 4 and the guard ring 6.

Further, since the guard ring 6 is made of stainless steel, its surface temperature is likely to be high, and there is a risk that it may be touched and burned.

Therefore, an object of the present invention is to provide a cooker that solves these problems.

[0010]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention comprises a cooker main body and a cooking pot which is detachably mounted on the cooker main body, and is provided on an upper edge of a guard provided around the heating device of the cooker main body. In a cooker in which a stop rib is provided and a guard ring is removably placed on the guard, the guard link is formed of synthetic resin, and the guard ring is straddled over the inner peripheral surface of the guard ring. The structure is such that an engaging recess that engages with the inner and outer surfaces is provided.

[0011]

[Action]

 In the above cooking device, when cooking with a deep-bottomed pan, put the guard ring on the guard and engage the engagement recess of the guard ring with the locking rib on the upper edge of the guard. The pan is placed on the heating device of the cooker body for cooking. At this time, since the engagement recess of the guard ring is engaged with the inner and outer surfaces of the locking rib, it is difficult to disengage even if an external force acts. In addition, since the guard ring is made of synthetic resin, it is easy to match the color of the guard ring that is generally made of synthetic resin, and since it has a large specific heat, it is less susceptible to burns than metal ones.

[0012] When cooking using a pan with a shallow bottom, the guard ring is removed and cooking is performed in the usual manner.

[0013]

【Example】

 As shown in FIGS. 1 and 2, the electric cooker of the embodiment comprises a combination of a cooker body 10, a pot 11 having a relatively deep bottom and a pot 11 'having a shallow bottom (see FIG. 2).

The cooker main body 10 has a heat-resistant synthetic resin guard 13 surrounding the heating device 12, and a bottom portion 14 extending to the lower edge of the guard 13 and a separate bottom plate 15 are used for cooking. It constitutes the bottom surface of the container body 10.

A heat shield plate 17 is attached to the upper portions of the bottom portion 14 and the bottom plate 15 via a mounting member 16, and the heating device 12 is attached to the upper portion of the heat shield plate 17. The heating device 12 is composed of a heater 18 and a heating plate 19, and the heating temperature is adjusted by operating a temperature adjusting lever 21.

The peripheral portion of the heat shield plate 17 rises at a required distance from the inner peripheral surface of the guard 13 to prevent the heat of the heating device 12 from being directly transferred to the guard 13. is doing.

The upper surface of the guard 13 is an inclined surface 22 that descends outward, and a locking rib 23 that protrudes upward is formed at the inner peripheral edge of the inclined surface 22. The guard ring 24 is detachably mounted on the inclined surface 22 (see FIG. 1). This guard ring 24 is also made of heat-resistant synthetic resin, and its outer peripheral surface is formed with a diameter of a size that is continuous with the outer peripheral surface of the guard 13 without any step, and the pan 11 placed on the heating device 12 described above is formed. It has a height that surrounds almost the upper half of the peripheral surface.

Further, on the inner peripheral surface of the guard ring 24, engaging portions 25 that engage with the locking ribs 23 are formed at several locations (see FIGS. 3 and 4). Each of the engaging portions 25 includes a locking wall 26 that hangs downward from the upper end of the inner peripheral surface of the guard ring 24, and a connecting rib 27 that is integrally formed between both sides of the locking wall 26 and the guard ring 24. It is composed of

An engaging recess 28 is formed between the lower end of the locking wall 26 and the connecting rib 27, and the engaging recess 28 straddles the locking rib 23 and engages with both inner and outer surfaces thereof. , Stabilize the posture of the guard ring 24.

Further, small ribs 29 are provided on the shoulder portion of the guard ring 24 so as to project over the entire circumference of several places. This small rib 29 has the guard ring 24 placed thereon as shown in FIG. The support of the guard ring 24 prevents the guard ring 24 from being damaged by the heat of the pot 11 'by avoiding contact with the entire upper edge of the guard ring 24.

In place of the small rib 29, an inverted U-shaped support metal fitting 31 is insert-molded on the upper end of the engaging portion 25 (see the chain double-dashed line in FIG. 3), and the upper end of the support metal fitting 31 is The flange of the pot 11 ′ that is erroneously placed may be supported by the support fitting 31 by projecting it slightly above the upper edge of the guard ring 24.

The electric cooker of the embodiment is as described above, and when the deep-bottomed pot 11 is used, the guard ring 24 is placed on the guard 13 as shown in FIG. , The gap between the guard 13 and the pan 11 is reduced, and the thermal efficiency can be improved. When using a pan 11 'with a shallow bottom, remove the guard ring 24 as shown in FIG. Cook by heating.

[0023]

[Effect of device]

 As described above, according to the present invention, by forming the guard ring of synthetic resin, it is easy to form a complicated shape such as an engaging recess that engages with the inner and outer surfaces of the locking rib of the guard. The engaging recess allows the guard ring to be stably engaged with the locking rib of the guard, and maintains a stable posture even if some external force is applied.

Further, since the material and color of the guard ring can be unified with those of the guard, it is possible to provide a cooker with an excellent appearance design, which has a sense of unity between the guard and the guard ring as the appearance of the cooker body. It is possible, and even if you touch the guard ring carelessly, there is no danger of getting burned.
