[0008]

However, in the above-described jar rice cooker, when the lid is opened, the top surface of the lid comes out behind the rear part of the main body, and when there is a wall surface behind the rice cooker, the lid is closed. The top surface is severely damaged, and the operation section provided on the lid section is strongly pressed, so that the operation section components inside the lid may be damaged (FIG. 6).

[0009] In addition, since the opening of the lid does not open completely perpendicular to the main body, the lower surface of the lid may be damaged when pouring rice in the pan or attaching / detaching the pan, and sometimes the rice cooker main body is pulled back once. After that, inconvenience of having to operate each time has arisen. This, of course, makes it difficult to determine the position of the rice cooker, as well as the inconvenience of using the main unit.As a result, the installation area of the rice cooker is also larger than the area of the main unit. Was.

[0010] The present invention solves the above-mentioned problems, and when the lid is opened, the lid top surface does not contact the wall surface and the installation area of the rice cooker is reduced by the area of the main body when there is a wall behind the rice cooker. It fits in.

[0011]

In order to solve the above-mentioned problems, the present invention provides a pot which is detachably housed inside a main body,
A lid is provided to cover the pot and the main body, the lid is openable and closable via a rear hinge shaft, and a top surface of the lid is located forward of a rear surface of the main body when opened.

[0012]

According to the first aspect of the present invention, when there is a wall surface behind the rice cooker, when the lid is opened, the top surface of the lid does not contact the wall surface and the installation area of the rice cooker is reduced. It has the effect of fitting in the area of the main body.

[0013] According to the second aspect of the present invention, even with the carrying handle, when the lid is opened, the top surface of the lid does not come into contact with the wall surface, and the installation area of the rice cooker is equal to the area of the main body. It has the effect of fitting in.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS.

In FIG. 1, a main body 1 is opened like a conventional jar rice cooker, and a pot 2 for accommodating a food to be heated is arranged inside the main body 1, and a protective frame on which the pot 2 is placed. 3 and a bottom heater 4 as a pan bottom heating means arranged on the outer periphery of the protective frame 3 are fixed. A bottom sensor 5 for detecting the temperature of the pan bottom surface 28 is disposed on the pan bottom surface 28 as pan temperature detecting means, and means for estimating the rice cooking and heat retaining state from the temperature is employed. A side heater 6 is disposed on the side of the protective frame 3 as a pot side heating means for heating the side of the pot. 21 is a carrying handle.

The upper opening portions of the main body 1 and the pan 2 are openably and closably covered by a lid 7. The lid 7 is provided on one side of the main body 1 with a hinge shaft 8 which is pivotally supported so as to be openable and closable. On the opposite side, the main body 1 has an engaging portion 10 that engages with the lid 7 via the hook button 9. A hinge spring 11 is provided on the hinge shaft 8 so that a force is applied to the cover 7 in the cover opening direction (FIG. 2).

Reference numeral 7a denotes an outer lid forming the outer surface of the lid 7.
An outer lid cover 7b covers the pot side of the outer lid 7a. The outer lid cover 7b has a lid heater 1 as a heating means for heating the lid.
2 are arranged.

Further, a heating plate 13 which is heated by heat generated from the lid heater 12 is disposed on the side of the outer lid cover 7b. The heating plate heat generating portion 13a that generates heat is usually made of aluminum, and in the case of IH, stainless steel or iron-based metal is used as a material. Further, a lid sensor 14 for detecting the temperature of the heating plate 13 is provided so as to be in contact with the heating plate 13, and means for estimating the rice cooking and heat retaining state from the temperature is employed.

The inside of the lid has a steam port 7c through which steam from the cooking pot is discharged. A steam cylinder 15 is provided at the steam port 7c. The steam cylinder 15 prevents the tongue during cooking from spilling out of the lid.

Reference numeral 16 denotes a display unit for displaying the operation state of the rice cooker. Reference numeral 17 denotes an operation unit for inputting operation of the operation of the rice cooker. Reference numeral 18 denotes a control unit which controls the heating power of the bottom heater and the lid heater based on an input signal from the operation unit 17 and outputs a signal for displaying the operation state of the rice cooker on the display unit.

Here, a feature of the present invention is that when the lid is opened, the lid top surface 20 is located forward of the rear of the main body (FIG. 3). When the lid is opened, the lid top surface 20 does not come into contact with the wall surface, so that the lid top surface is not strongly damaged or the operation unit provided on the lid portion is not strongly pressed. In addition, the inconvenience of having to operate each time after pouring the rice in the pot or damaging the bottom of the lid when attaching or detaching the pot, sometimes pulling back the rice cooker body once,
Since the installation area of the rice cooker falls within the area of the main body, the rice cooker can be installed so as to be in contact with the wall surface even if the wall surface is present at the rear of the rice cooker.

When the portable device has the handle 21 for carrying, the cover top surface 20 is located forward of the rear portion of the main body including the handle 21 when the cover is opened, so that the portable device has the handle 21 for carrying. Also in this case, it is not necessary to strongly damage the top surface of the lid or to strongly press the operation unit provided on the lid. In addition, there is no inconvenience that the bottom surface of the lid is damaged when pouring the rice in the pot or attaching / detaching the pot, and sometimes the rice cooker body must be pulled back once and then operated every time. Since the area is within the body area, even if a wall surface is present at the rear of the rice cooker, the rice cooker can be installed so as to be in contact with the wall surface.

[0023]

As described above, according to the first aspect of the present invention, when there is a wall surface behind the rice cooker, when the lid is opened, the top surface of the lid does not come into contact with the wall surface, and This has the effect that the installation area can be accommodated by the area of the main body.

According to the second aspect of the present invention, even when the rice cooker has a handle, if the wall is behind the rice cooker, when the lid is opened, the top surface of the lid contacts the wall. There is an effect that the rice cooker can be installed within the area of the main body without being in contact with the rice cooker.
