Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating cooker used at home.

[0002]

2. Description of the Related Art A roaster portion provided in a conventional embedded induction heating cooker will be described as an example.

Conventionally, this kind of embedded induction heating cooker has a structure as shown in FIGS. 5 and 6. 5 is a perspective view showing the whole, and FIG. 6 is a sectional view taken along line AA in FIG.

In the figure, reference numeral 1 is a sink, and a top heater portion 3 having a heating coil inside and an upper surface formed of a ceramic plate 2 is dropped into an opening portion of the upper surface, and the sink 1
A roaster case 4, a heater 5 for the roaster, a circuit board equipped with many electronic components, and a cooker main body 6 having a blower and the like are installed inside the front opening.
A kangaroo pocket type operation unit 7 is provided in the cooker body 6 together with a liquid crystal type display unit 8.

Reference numeral 9 is a roaster door, which is a door A11 on which the glass 10 is placed, a door B12 which holds it down from the front, and a glass.
It is formed from a handle 13 that holds 10 with the door A11 at the upper side, and is fixed with screws 14 at the top and bottom. Reference numeral 15 denotes a hinge shaft, which is inserted into and engaged with a bearing 17 provided below the front frame 16, so that the roaster door 9 is rotatable. Reference numeral 18 is a pan that is slidably mounted in the roaster case 4.

The front frame 16 is fitted to the roaster case 4, and a gap (a) required for rotating the roaster door 9 is brought into contact with a rib 19 formed in a semicircular shape on the door A. It is packed up by things.

[0007]

Generally, since the roaster part of the embedded cooker has a rear exhaust air structure, in order to prevent smoke from leaking from the roaster door part, the sealing property of the door part is increased or the pressure loss is reduced. It is necessary to increase the flow rate to form a convection path to the exhaust hole provided at the rear of the main body. However, since the temperature around the door portion of the roaster portion is extremely high and a rubber-based sealing material or the like cannot be used, the pressure loss of the door portion must be increased.

However, in such a conventional structure, the means for preventing smoke leakage from the roaster door 9 is the door A11.
Since only the semi-circular rib 19 formed on the front plate 16 makes a line contact with the front plate 16, even if there is a slight gap, smoke will leak from the roaster door 9.

Therefore, the present invention solves the above-mentioned conventional problems. Even when the user cooks a lot of smoke (for example, saury fish with a large amount of oil and fat), smoke is generated from the door of the roaster. It is a first object of the present invention to provide a sanitary and high-quality heating cooker that does not cause the user to feel uncomfortable without being disturbed and prevents the sink from becoming dirty due to smoke leakage.

The second purpose is to improve the performance against smoke leakage. The third purpose is to further improve the performance against smoke leakage.

[0011]

In order to achieve the above-mentioned first object, the first means of the present invention is a front surface of a cooking chamber provided with a retractable door portion in the front and a heating heater. Has a front frame for holding, and the contact portion between the door portion and the front frame forms a flat surface portion.

In order to achieve the second object, the second aspect of the present invention
The above means is to provide a further contact portion having a step inside the contact portion between the door portion and the front frame.

In order to achieve the third object, the third aspect of the present invention
In this means, the roof part provided above the front frame and the handle part provided on the door part are brought close to or in contact with each other.

[0014]

According to the first means of the present invention, the user cooks with a lot of smoke (for example, saury fish with a lot of oil and fat), and a gap is opened between the roaster door and the front frame due to assembly variations. Even when the flat surface increases pressure loss, smoke does not leak from the roaster door and does not cause discomfort to the user, and also prevents the sink from becoming dirty due to smoke leakage.
It is possible to provide a sanitary and high-quality heating cooker.

Further, in the second means, by providing a further stepped contact portion inside the contact portion between the door portion and the front frame, the ascending path is provided for smoke generated along the roaster door. Since it bends, the pressure loss increases and the performance against smoke leakage can be improved.

In the third means, the pressure loss of the roaster door portion is further increased by bringing the roof portion provided above the front frame and the handle portion provided on the door portion close to or in contact with each other. Therefore, the performance against smoke leakage can be further improved.
