Description

[Detailed Description of the Invention] The present invention relates to a lid structure for a gas rice cooker, and particularly to a removable single-opening lid structure.

The upper frame of the gas rice cooker is a drawn steel plate product.
Enamel treatment is applied as surface treatment. Since the enamel film has poor impact resistance, when the outer lid is suddenly closed from a half-open state, its free end comes into contact with the upper end of the upper frame, and the enamel film may peel off.

The object of the present invention is to prevent the enamel film from peeling off by preventing its free end from coming into contact with the upper edge of the upper frame when the outer lid is closed.

The basic structure of the present invention is that a pair of handles are arranged on the diametrical line at the upper end of the upper frame, a fulcrum shaft is provided on one of the handles, and one of a pair of holding pieces is provided on the diametrical line of the lid body. In a lid structure in which the lid body is supported by the upper frame in a single-opening manner, the other holding piece of the lid body can be freely engaged and detached from the engagement lever provided on the other handle. The upper end of the engagement lever is made to correspond to the above-described structure and to come into contact with a bent extension piece integral with the fulcrum shaft of the engagement lever in the closed position of the lid body. This is because the inner surface is sloped inward.

With the above structure, when the lid is closed, the lower part of the holding piece, which is the free end of the lid, comes into contact with the bent extension piece of the fulcrum shaft in one of the handles facing the holding piece. This prevents the free end of the lid from coming into contact with the upper edge of the upper frame, thereby preventing the enamel upper frame from peeling off.

Hereinafter, embodiments of the present invention will be explained based on the drawings.

Fig. 1 shows a partially cutaway sectional view of a gas rice cooker using the lid body of the embodiment of the present invention.
The upper frame accommodates and places the rice cooking pot 2, and the upper frame is placed on a lower case 3 equipped with a main burner and other devices.

The upper frame 1 is covered with a lid 4, and a pair of holding pieces 5, 6 are protruded from the periphery of the upper surface of the lid, and the upper end of the upper frame corresponds to the holding pieces 5, 6. A pair of handles 7 and 8 are attached to the handles.

The handles 7 and 8 have a cavity 10 with an opening 9 above.
A fulcrum shaft 11 is fixed in the hollow space of one of the handles 8, and bearings 12, 12 protruding from the lower surface of one of the holding pieces 6 correspond to the holding pieces 6 in a freely engaging and detachable manner. For this reason, a notch 13 is provided in the bearing portion.

The tip of the other holding piece 5 is a flat part 14 like the holding piece 6, but a hanging piece 15 is connected to the tip of the flat part, and both sides of the hanging piece 15 are as shown in FIG.
As shown in FIG. 3, there are sloped sides 16, 16 that slope downward and inward. This hanging piece 15 can enter into the space 10 of one handle 7, and the engaging part 18 and operating part 19 of the engaging lever 17 built into the handle and made swingable can be moved outward from the handle. stand out. The engagement lever has one shaft piece of a substantially U-shaped metal fitting 20 fixed in the handle 7 as a fulcrum shaft 21, and a spring 22 is interposed between it and the handle 7 or the upper frame 1. A return force is applied to the engagement lever. The upper inner surface of the engaging portion 18 of the engaging lever 17 is an inclined surface, and the position of the inclined surface is appropriately set in accordance with the tip of the holding piece 5.

Further, the other shaft piece 23 of the metal fitting 20 is lifted upward in the middle, and this protrusion 24 is located slightly above the upper edge of the upper frame 1.
(Fig. 1, Fig. 2) Furthermore, the hollow space 10 of the handle 7 has a structure as shown in Fig. 2,
Grooves 25 and 26 are formed on both side walls of the space, and when the spring 22 and the engagement lever 17 are attached, the free end of the metal fitting 20 is inserted into the groove 25 on one side and the connecting portion 2 on the other side.
7 is inserted into the other groove 26, and then the handle is attached to the upper frame 1, and the assembly is completed as shown in Fig. 1. Also, in Fig. 1, 28 is the inner lid,
A lid body 4 covers the rice cooker 2 from the outside of the inner lid 28, and a central knob shaft 29 comes into contact with a presser shaft 30 provided on the central inner surface of the lid body 4.

In the case of the embodiment described above, in the closed state, it is in the state shown in FIG.
The other holding piece 5 engages with an engaging lever 17 provided on the handle 7 to hold the lid body on the upper frame 1, and a presser shaft protruding from the central inner surface of the lid body 4 30 pushes down the knob shaft 29 of the inner lid 28, and the periphery of the inner lid is pressed against a stepped portion 31 wound around the mouth of the rice cooker 2.

When the engagement lever 17 is pushed outward against the spring 22, the engagement portion 18 of the engagement lever and the holding piece 5
As a result, the lid body 4 is opened in one direction using the bearing part 12 of the other holding piece 6 as a fulcrum, and in the fully open position, the flat part of the holding piece 6 is on one side of the mouth part 9 of the handle 8. and is held in an inclined state (the state indicated by the two-dot chain line in FIG. 1).

The lid body 4 may suddenly close from this fully open position or from the half open position, but even in this case, the holding piece 5 comes into contact with one shaft piece 23 of the metal fitting 20 provided on the handle 7 and is engaged. The mating lever 17 automatically engages and holds it. The attachment positions of the holding pieces 5 and 6 to the lid body 4 are set appropriately in advance so that there is an appropriate gap between the lower edge of the lid body 4 and the upper edge of the upper frame 1 in the closed position. Therefore, even if the above-mentioned sudden closing occurs, the lid body 4 will not come into contact with an impact, and the enamel film will not peel off due to such a cause.

In the case of the illustrated embodiment, the hanging piece 15 of the holding piece 5
Since both sides of the holding piece 6 have inclined parts 16, 16, even if there is a margin between the bearing part 12 of the other holding piece 6 and the fulcrum shaft 11, and the rotational posture of the lid body 4 becomes unstable, The hanging piece 15 reliably enters the opening 9 of the handle 7 by the guidance of the inclined parts 16, 16. That is, the engagement between the holding piece 5 and the engagement lever 17 is always reliable.

Since the present invention has the above configuration, it has the following advantages. That is, the engagement and retention of the lid body is always ensured by the guiding action of the inclined portions provided on both sides of the hanging piece at the tip of the holding piece that engages with the engagement lever.
