Description

[Detailed Description of the Invention] The present invention relates to an electric cooker for cooking food materials.

Generally, an electric cooking device such as a toaster oven as shown in FIG. 1 is used. In the figure, reference numeral 1 denotes a toaster oven case, and the front side of the case 1 is provided with an opening/closing door 2, a timer section 3, a heater switching section 4, an open/distant heat switching lever 5, and the like. A fermentation chamber is formed in the case 1, and the food material is housed in the fermentation chamber and is heated and cooked using a heater. FIG. 2 is a longitudinal sectional view of the toaster oven viewed from the front, and 6 in the figure is the incubation chamber. The incubation chamber 6 is formed by partitioning a space inside the case 1 by side walls 7, 7 and a rear wall 7a of the case, an upper reflector 8, and a bottom plate 9. The incubation chamber 6 is provided with upper heaters 10, 10 and lower heaters 11, 11 as rod-shaped electric heating elements. , 11 are attached to the lower part of the housing. In addition, this incubation chamber 6 also has a baking tray 12.
A cooking plate 13 is placed on top of the grill.

The upper reflecting plate 8 is provided so as to be movable up and down by an arm mechanism 14. This arm mechanism 14 is connected to a direct flame/distant flame switching lever 5 on the front of the case 1, and by moving the direct flame/distant flame switching lever 5 up and down, the upper reflector 8
is configured to move vertically. Therefore, the distance between the upper heater 10 and the cooking plate 13 can be adjusted as appropriate, and the degree of burnt food material on the cooking plate 13 can be adjusted.

By the way, as shown in FIG. 3, the terminal portions of the upper heaters 10, 10 protrude outside the side wall 7 of the housing, and a conductive plate 15 is installed between these terminals. For this reason, openings 16 and 1 are provided in the side wall of the housing 7.
6, and these openings 16, 16 are covered from the inside by the side edges 8a of the upper reflecting plate 8 to prevent heat dissipation within the incubation chamber 6.

However, in the conventional toaster oven, the terminals of the upper heaters 10, 10 protrude outside the side wall of the housing 7, so two openings 16, 16 are required. The height of the openings 16, 16 in the vertical direction is equal to the movement of the upper reflecting plate 8.
The areas of the openings 16, 16 were widened. For this reason, there was a problem in that the amount of heat dissipated from the openings 16, 16 increased even though they were covered by the side edges 8a.

In addition, the conductive plate 15 protruded outside the side wall 7 of the housing, and there was a risk that the link mechanism 14 provided on the outside of the side wall 7 of the housing would come into contact with the conductive plate 15, causing electrical leakage.

The present invention has been made in consideration of the above circumstances, and its object is to provide an electric cooker which reduces the area of the opening in the side wall of the housing, thereby reducing the amount of heat dissipated from this opening, and which does not have the risk of electrical leakage due to contact between a good conductor and the reflector operating mechanism.

The electric cooker of the present invention houses the object to be roasted in the housing, and includes an upper reflector that forms a roasting chamber together with the housing and moves up and down within the housing to change the volume of the roasting chamber. a plurality of rod-shaped electric heating elements are mounted parallel to each other on the lower surface of the reflector, which is the heat-reflecting surface side; a reflector actuating mechanism is provided on the outer surface of the side wall of the housing to make the reflector movable; A connecting member is provided that is inserted through the opening provided in the side wall of the casing, and the connecting member connects the upper reflector and the reflector operating mechanism, and is a good conductor that electrically connects the plurality of electric heating elements. is disposed on the upper surface of the upper reflector through the gap between the upper reflector and the connecting member.
Therefore, there is no risk that the reflector operating mechanism provided on the outside of the side wall of the casing will come into contact with the good conductor provided on the upper surface of the upper reflector, and the area of the opening provided in the side wall of the casing is reduced. It is possible to reduce the amount of heat dissipated from the opening.
