Abstract

A cooker includes a heating coil, a housing accommodating the heating coil, a top plate provided on the housing, a partition defining a storage in the housing and below the heating coil and including a first partition extending parallel to the top plate and a second partition extending perpendicularly to the first partition, a first facing wall facing the first partition with a gap defined between the first facing wall and the first partition, a second facing wall facing the second partition with a gap defined between the second facing wall and the second partition, a heat-insulating layer provided between the first partition and the first facing wall, and a heat-insulating layer provided between the second partition and the second facing wall, the heat-insulating layers being each made of a substance having a lower thermal conductivity than one of the first facing wall and the second facing wall.

First claim

The invention claimed is:

1. A cooker, comprising:
a heating coil;
a housing accommodating the heating coil;
a top plate provided on the housing;
a partition defining a storage in the housing and below the heating coil and including a first part of the partition extending parallel to the top plate and a second part of the partition extending perpendicularly to the first part of the partition;
a first facing wall facing the first part of the partition with a gap defined between the first facing wall and the first part of the partition;
a second facing wall facing the second part of the partition with a gap defined between the second facing wall and the second part of the partition;
a heat-insulating layer provided between the first part of the partition and the first facing wall; and
a heat-insulating layer provided between the second part of the partition and the second facing wall, wherein
the heat-insulating layers each have a lower thermal conductivity than a thermal conductivity of a corresponding one of the first facing wall and the second facing wall,
the housing or the top plate has an exhaust vent communicating with an inside of the housing,
in a state where the cooker is seen in a direction perpendicular to an open face of the exhaust vent, at least part of the first facing wall is overlapped by at least part of the exhaust vent, and
the first facing wall is configured to guide air in the housing to the exhaust vent.

2. The cooker of claim 1 , wherein, in a plan view, the first part of the partition is encompassed by the first facing wall.

3. The cooker of claim 1 , wherein at least one of the heat-insulating layers includes an air layer.

4. The cooker of claim 3 , further comprising an air-sending device provided in the housing, wherein an air passage allowing an air outlet of the air-sending device and at least one of the heat-insulating layers to communicate with each other is provided.

5. The cooker of claim 4 ,
wherein a first opening allowing the gap between the first facing wall and the first part of the partition and an area above the first facing wall to communicate with each other is provided, and
wherein a second opening allowing the gap between the second facing wall and the second part of the partition and the air outlet of the air-sending device to communicate with each other is provided.

6. The cooker of claim 4 ,
wherein the partition has an opening communicating with an inside of the storage, and
wherein the cooker includes a connecting duct connecting an air inlet of the air-sending device and the opening provided at the partition to each other.

7. The cooker of claim 6 , further comprising a door configured to open and close an open part provided at a front face of the storage, wherein the opening provided at the partition is positioned closer to a rear of the storage than is a center of the storage in a direction from a front to the rear of the storage.

8. The cooker of claim 1 , further comprising an air-sending device provided in the housing,
wherein the partition has an opening communicating with an inside of the storage, and
wherein the cooker includes a connecting duct connecting the opening provided at the partition and an air inlet of the air-sending device to each other.

9. The cooker of claim 8 , further comprising a door configured to open and close an open part provided at a front face of the storage, wherein the opening provided at the partition is positioned closer to a rear of the storage than is a center of the storage in a direction from a front to the rear of the storage.

10. The cooker of claim 1 , wherein at least one of the heat-insulating layers includes a heat-insulating material having a lower thermal conductivity than a thermal conductivity of a corresponding one of the first facing wall and the second facing wall, and wherein the heat-insulating material is laid over a corresponding one of the first part of the partition and the second part of the partition.

11. The cooker of claim 1 ,
wherein the first facing wall is made of metal, and
wherein the heating coil is positioned above the first facing wall.

12. The cooker of claim 11 , wherein the first facing wall is made of nonmagnetic metal.

13. The cooker of claim 1 , wherein at least part of an inner surface of the partition is provided with a heat-insulating material that has a lower thermal conductivity than a thermal conductivity of the partition.

14. The cooker of claim 1 , further comprising a cooking pan to be heated by the heating coil, the cooking pan being stored in the storage.
