Embodiment 1.
The first embodiment will be described with reference to FIGS. 1 to 3.
FIG. 1A is a perspective view of a toaster showing the first embodiment. FIG. 1B is a perspective view showing a state in which the door is opened in the toaster of FIG. 1A. FIG. 2A is a top view of a toaster showing the first embodiment. FIG. 2B is a side view of the toaster of FIG. 2A. FIG. 3 is a cross-sectional view taken along the line AA of FIG. 2 (a).

The toaster 1 includes an outer case 10 that forms an exterior, an inner case 20 that is provided inside the outer case 10 and forms a cooking space R that heats the cooked food F, and a cooked food that is provided inside the inner case. A gap between the heating means (upper heater 31, lower heater 32) for heating F, the mounting portion 40 on which the cooked food F is placed, the door 50 that separates the inside and the outside of the cooking space R, and the door 50 and the inner case 20. A seal portion 60 for filling the door is provided.

The outer case 10 has an outer case top surface 10a, an outer case left surface 10b, an outer case right surface 10c, an outer case rear surface 10d, and an outer case bottom surface 10e. There is.
The outer case top surface 10a is provided with a lock portion 11 in which the door 50 holds the outer case front opening 10f in a closed state. The lock portion 11 is formed with a recess 11a that opens downward on one end side, and the other end side is pivotally supported by the top surface 10a of the outer case. The lock portion 11 may be provided on the door 50 and may be pivotally supported so as to be held in a closed state with respect to the main body.
Further, the bottom surface 10e of the outer case is provided with leg portions 12 for forming a clearance between the toaster 1 and the installation position.

Next, the inner case 20 is a box body formed by bending a sheet metal, and has an inner case top surface 20a, an inner case left surface 20b, an inner case right surface 20c, an inner case rear surface 20d, an inner case bottom surface 20e, and an inner case front surface 20f. An inner case front opening 20f is formed inside the front surface 20f. Further, the space inside the inner case 20 is a cooking space R, and the cooking material F can be taken in and out of the cooking space R from the front opening 20f.
The inner case 20 has a hermetically sealed structure so as to reduce gaps and openings other than the opening 20f in front of the inner case.

Further, the size of the cooking space R formed in the inner case 20 is determined based on the size of one general bread. For example, the relationship between the size A from the inner case front opening 20f to the inner case rear surface 20d, which is the depth, and the size B from the inner case right surface 20c to the inner case left surface 20b, which is the width, is
When A = about 150 mm, B = about 180 mm, and when A = about 180 mm, B = about 150 mm.

The inner case 20 configured in this way is provided inside the outer case 10. In a state where the inner case 20 is provided inside the outer case 10, a gap D is formed between the outer case 10 and the inner case 20. The inner case front surface 20f is located on the front side of the gap D.
The gap D is formed for heat insulation that makes it difficult for heat to be transferred from the inner case 20 to the outer case 10 during the heating operation. In particular, in order to further improve the heat insulating performance, a heat insulating member may be provided in the gap D.

Further, the inner case front surface 20f is a portion that fills the gap between the outer case 10 and the inner case 20, and may be formed by bending the front end of the inner case 20 or may be composed of independent members.
A seal portion 60 is provided on the front surface 20f of the inner case. The seal portion 60 is located outside the inner case front opening 20f and is provided so as to surround the inner case front opening 20f. That is, a seal portion 60 is provided on the peripheral edge of the inner case front opening 20f, which is an opening for taking in and out the cooked food F. Further, the seal portion 60 is made of a heat-resistant member such as silicon.

The heating means is provided inside the inner case 20 and heats the cooking space R to a state suitable for baking bread. The heating means includes an upper heater 31 provided on the top surface 20a side of the inner case and a lower heater 32 provided on the bottom surface 20e side of the inner case. As the upper heater 31 and the lower heater 32, a planar heater may be used. The upper heater 31 and the lower heater 32 may be located between the outer case 10 and the inner case 20.
Further, the size H of the lower heater 32 to the upper heater 31 in the height direction is set to be 100 mm or less. This is because the area where the bread, which is the cooked food F, is located is made compact, so that the steam released from the bread is trapped inside the cooking space R, and the bread, which is the cooked food F, is not over-dried when baking. This is to give the surface a brown color in a short time.

The power line for supplying power to the lower heater 32 and the upper heater 31 passes through an opening opened in the inner case 20, but it is desirable that the gap between the power line and the opening edge is made as small as possible. For example, it is preferable to provide a sealing member in the opening through which the power line of the inner case 20 passes to reduce the gap between the power line and the opening edge.

The mounting portion 40 is provided in the inner case 20 between the upper heater 31 and the lower heater 32 so that the mounting portion 40 can slide in the front-rear direction while approaching the lower heater 32 side. The mounting portion 40 is composed of a mesh-like member, has a mounting surface 41 on which bread is placed, and has a front end connected to the door 50. Further, the size of the placing portion 40 is such that a general bread can be placed.

The lower end of the door 50 is pivotally supported by a hinge 51 with respect to the outer case 10 so as to open and close the inner case front opening 20f and the outer case front opening 10f. When the door 50 is open, the cooked food F can be taken in and out of the cooking space R.
When the door 50 is closed, the door 50 is in close contact with the seal portion 60, and the cooking space R is sealed from the outside of the oven toaster 1. In particular, the lock portion 11 ensures that the door 50 keeps the inner case front opening 20f closed, and makes the cooking space R a closed space.
That is, one end of the door 50 is pivotally supported by the outer case 10, and the other end is leasably fixed to the outer case 10 by the lock portion 11.

By configuring the oven toaster 1 as described above, it is possible to make the cooking space R a closed space when cooking the cooked food F by heating. As a result, more steam released from the cooked food F during cooking can be retained inside the cooking space R, and the cooked food F can be baked without being overdried.
Further, since the cooking space R is a closed space, it is possible to bake the cooked food F in a shorter time. In particular, since the door 50 can be fixed to the outer case 10 in a state of being in close contact with the seal portion 60 by the lock portion 11, the cooking space R can be kept in a more closed space.
In the present embodiment, the seal portion 60 is provided on the front surface 20f of the inner case, but the seal portion 60 may be provided on the door 50.

Embodiment 2.
The second embodiment will be described with reference to FIG. The same components as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.
The door 50 is provided with a window portion 53 for visually recognizing the cooking space R from the outside of the door 50. The window portion 53 is made of glass so that the cooking space R can be confirmed.
Further, the door 50 is provided with a convex portion 52 projecting toward the inner case 20 side. The convex portion 52 comes into contact with the inner case 20 in a state where the door 50 is closed. Specifically, the convex portion 52 contacts the inner case front surface 20f in a state where the door 50 is closed.
The position of the inner case front surface 20f where the convex portion 52 comes into contact is the outer portion of the seal member 60.

As described above, since the convex portion 52 forming a part of the door 50 is configured to be in contact with the inner case 20, heat is generated from the inner case 20 heated by the heat generated in the cooking space R during cooking. Heat is transferred to the convex portion 52 by conduction to heat the door 50.
As a result, the temperature of the door 50 rises, and dew condensation that occurs on the outer surface of the door 50 and the window portion 53 can be prevented.
In particular, by integrally forming the convex portion 52 with the member constituting the door 50, heat transfer by heat conduction becomes efficient, the door 50 can be heated more efficiently, and dew condensation can be prevented. it can.

Embodiment 3.
The third embodiment will be described with reference to FIG. The same components as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.
The door 50 is provided with a valve 54 for eliminating the difference in air pressure between the inside and the outside of the cooking space R. By operating the valve 54, the inside and the outside of the cooking space R are communicated with each other, and air is circulated from the inside to the outside of the cooking space R or from the outside to the inside of the cooking space R. This is to eliminate the pressure difference between the inside and the outside of the cooking space R.

As described above, since the door 50 is provided with the valve 54 for eliminating the pressure difference between the inside and the outside of the cooking space R, the inside of the cooking space R during cooking is steam generated from the cooked food F. Therefore, even if the air pressure is higher than that of the external space, the pressure difference between the inside and the outside of the cooking space R can be eliminated by operating the valve 54.
As a result, even if the inside of the cooking space R becomes high pressure during cooking, the door 50 can be safely opened.

Further, even if the inside of the cooking space R is cooled after cooking and the air pressure becomes lower than the outside, the pressure difference between the inside and the outside of the cooking space R can be eliminated by operating the valve 54. The door 50 can be opened safely.
In the present embodiment, the valve 54 is operated by the user to eliminate the difference in air pressure between the inside and outside of the cooking space R, but the valve 54 is the difference in air pressure between the inside and outside of the cooking space R. When the pressure exceeds a certain level, it may be automatically opened so as to eliminate the pressure difference between the inside and the outside of the cooking space R.
