Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a door device for a cooking device such as a toaster oven, and an object thereof is to enable the door device itself to be easily removed from the main body of the cooking device.

Conventionally, the door device of a cooker such as a toaster oven is pivoted on the main body, and in order to remove the door device for reasons such as servicing, the door device itself must be disassembled or a part of the cooker main body must be disassembled. There was a need.

As a result, the service quality was extremely poor.

The present invention aims to solve this problem and will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a main body of a toaster oven, and a door body 2 is pivotally supported by a shaft 3 at a front opening thereof so as to be freely openable and closable.

This door body 2 includes a front door frame 4, a rear door frame 5, a door glass 6, and a handle I.
It is made up of.

This front door frame 4 is formed with a front part 8 and an outer peripheral edge part 9 bent rearward from the periphery, and a window hole 10 is formed in the center of the front part.
A screw through hole (not shown) is bored in the upper part of the screw.

The rear door frame 5 consists of a rear surface part 12 and an inner peripheral edge part 11 whose periphery is bent forward, and has a window hole 13 in the center of the rear surface part and a screw through hole 14 in the upper part thereof.

Further, an inner abutting portion 15 is provided which is bent forward from the periphery of the window hole 13.

Below the window hole 13, a shaft 3 is inserted into a hole provided on the left and right inner peripheral edges.
is held through.

This shaft 3 always moves toward the stopper A in the direction of the arrow shown in FIG.
16 and the inner surface of the right inner circumferential edge.

This biasing force is stopped by the stopper B18 coming into contact with the inner surface of the left inner peripheral edge.

Reference numeral 19 denotes a shaft operating metal fitting. This shaft operating metal fitting 19 consists of an operating surface 20 and a sliding surface 21, and is bent into an abbreviated shape. The surface is interposed between the inner surface of the left inner circumferential edge and the stopper B18, and the urging force is stopped by the interposition of the operating surface of the shaft operating fitting 19.

An operation shaft hole 23 is provided above the hole for passing through the shaft on the left inner peripheral edge, and a part of the operation surface is covered so that it can be seen through the hole.

This operating shaft hole 23 is provided in a portion that is sufficiently exposed from the cooking device main body when the door body is opened as shown in FIG.

Next, to explain the assembled state, the window hole 13 of the rear door frame 5
has a substantially rectangular shape, and a part of the corner is rounded, and this rounded part is provided with a glass holding part 24 bent lower than the inner abutment part 15, as shown in FIG. The rectangular door glass 6 is held at , and its movement in the plane direction is restricted by the inner abutment part.The rear door frame 5 holding the glass 6 in this way is inscribed in the outer peripheral edge 9 of the front door frame 4. It is fitted in shape.

Reference numeral 25 denotes a grip, which is attached to the front surface 8 of the front door frame 4 from the rear door frame cutout surface 12 side with screws 26.

In this case, the inner circumferential edge tip 28 and the inner abutment tip 29 of the rear door frame 5 abut against the inner surface of the front surface 8 of the front door frame 4, and the tightening of the screw 26 remains constant.

Reference numeral 27 denotes a stopper piece formed by bending upward from the outer peripheral edge 9 below the front door frame 4.

To install the door, first insert the right protruding shaft, that is, the side where the compression spring is located, into the shaft support hole provided in the cooker body, and then insert the left shaft tip as shown by arrow C in Figure 5. While holding it down, insert it into the shaft support hole on the other side to complete the assembly.

Next, to explain how to remove it, open the door body and
As shown in the figure, insert the pin 30 into the operating shaft hole 23, push in the operating surface 20 of the shaft operating fitting 19, and remove the shaft 3 from the left shaft support hole, and then remove the right side.

In this case, a part of the sliding surface of the shaft operation fitting 19 comes into contact with a glass holding portion formed on the rear door frame 5, and the stopper is configured to prevent the shaft from entering the rear door frame 5.

As is clear from the above description, the present invention provides a shaft operating fitting for moving a shaft inside a door device consisting of a front door frame, a rear door frame, etc., and exposes the operating part of the shaft operating fitting, or It can be operated from the outside using a simple jig, and the door body, which is pivoted on the cooker body, can be easily removed, so the door body can be disassembled or a part of the body can be disassembled and removed. This is not necessary and the improvement in service quality can be measured.
