Description

[Detailed description of the invention] The present invention relates to a bottom lid device for a cooking device, and includes, for example, opening and closing the bottom lid that closes an opening to prevent dust from entering through a cleaning opening formed at the bottom of a roasting chamber. It relates to a structure that supports freely.

In a conventional cooking device of this kind, for example, in a roasting chamber, a retaining part is formed that engages with a locking part formed at the front end of the lower opening surface of the main frame to maintain the closed state of the bottom lid body. A structure is adopted in which the bottom cover body is biased by a spring, but with this structure, the bottom cover body moves forward when it is closed, creating a gap at the rear end of the opening, which causes dust to enter and become unsanitary. However, it also has the disadvantage of requiring a spring and requiring a large number of parts.

The present invention was developed in view of the above-mentioned drawbacks, and uses the elastic force of the reflector when the bottom cover is in the closed state to engage the engaging portion with the locking portion of the main frame to maintain the closed state. To provide a bottom lid device for a cooking appliance which prevents the formation of a gap in an opening when the bottom lid body is closed, prevents the intrusion of dust, etc., and reduces the number of parts such as springs.

The structure of the present invention includes a main frame having an opening formed on the lower surface and a locking part provided at one end of the opening, and a retaining part formed at one end that engages and disengages from the locking part of the main frame. and a bottom cover rotatably supported by the opening of the main frame, and a reflector attached to the main frame, and a long hole is formed in either the main frame or the bottom cover. At the same time, a shaft portion is formed on the other side to be pivotally supported by the elongated hole, and the engagement between the elongated hole and the shaft portion enables the bottom cover body to rotate, and the retaining portion is engaged with the locking portion. The bottom cover body is biased by the reflecting plate in a direction in which the retaining part engages with the locking part.

Next, the structure of an embodiment of the present invention will be explained with reference to the drawings.

Reference numeral 1 denotes a main frame attached to the case 2 of the roasting chamber (Figs. 4 to 6), which includes side plate members 3 and 3;
The front plate member 5 is engaged with the groove-like portion 4 formed in the lower part of the front plate member 5, and the side plate members 3, 3 are formed on the upper surface and back of the space formed in the both side plate members 3, 3. A reflecting plate 8 having a locking claw formed in the locking hole is provided.

The main frame 1 and the reflecting plate 8 form a roasting chamber 9 that is a cooking chamber that opens at the upper and lower front surfaces.

Also, the lower opening 10 of the front plate member 5 forming the upper frame 1
A locking portion 11 is formed in the lower portion of the front end side and protrudes toward the back side.

Further, a long hole 12 in the front-rear direction is formed at the lower rear end side of the side plate members 3, 3 of the main frame 1.

Reference numeral 13 designates a bottom lid body, which is formed into a dish shape and has a retaining portion 14 protruding forward from the upper edge of its front end to be engaged with and disengaged from the aforementioned locking portion 11.

Further, a support side portion 15 is formed at the rear end of the bottom cover body 13 and is inclined upward toward the rear side, and on both sides of the support side portion 15, a support side portion 15 is formed so as to be rotatable in the elongated hole 12 of the main frame 1. In addition, a shaft portion 16 that is inserted and supported so as to be movable in the front-back direction is protruded.

Further, a pressed side portion 17 is formed at the upper edge of the support side portion 15 of the bottom cover body 13 by bending it toward the back side.

The pressed side portion 17 comes into contact with an elastic side portion 18 formed at the lower part of the reflecting plate 8 in a forwardly inclined shape, so that the bottom cover body 13 is biased forward.

Note that a guide groove 19 in the front-rear direction is formed in the middle part of the side plate members 3, 3 of the main frame 1, and guide shafts 21 formed on both sides of the grill 20 are engaged with this guide groove 19, and this grill 20 is interlocked with a front door (not shown) of the case body 2 via a non-detachment mechanism, so that it is projected forward when the front door is opened, and is located within the roasting chamber 9 when the front door is closed.

Further, sockets 23 of electric heaters 22 are mounted on the inner surfaces of both side plate members 3, 3 of the main frame 1, located above and below the grill 20, respectively, facing each other.

Next, the operation of this embodiment will be explained.

As shown in FIGS. 2 and 4, the bottom cover body 13 has an opening 10
In the closed state, the pressed side portion 17 of the bottom cover body 13 is urged forward by the elastic side portion 18 of the reflection plate 8, and its engaging portion 14 is engaged with the locking portion 11 of the main frame 1, The bottom cover 13 is maintained in a closed state, and the rear end pressed side 17 of the bottom cover 13 is in contact with the elastic side 18 of the reflector 8, so that the rear end of the bottom cover 13 and the reflector are in contact with each other. There is no gap between the two.

Next, when the bottom cover 13 is opened, the front edge of the bottom cover 13 is pressed toward the back side as shown in FIGS. Long hole 1 resists the elasticity of 18
2 and the shaft portion 16, the engaging portion 1 is moved backward by the engagement guide between the engaging portion 1
4 is released from the locking part 11, and the bottom cover body 13 is rotated by the engagement guide between the elongated hole 12 and the shaft part 16, as shown in FIG. 6, and the bottom cover body 13 can be opened.

Furthermore, when closing the bottom cover 13, the bottom cover 13 is closed and pressed against the elasticity of the elastic side 18 of the reflector 8, and the engaging part 14 is moved inward from the edge of the locking part 11. When the pressure is released, the bottom cover 13 is moved forward by the elasticity of the elastic side 18 of the reflector 8, and the bottom cover 13 moves toward the engagement part 1.
4 is maintained in the closed state in which it is engaged with the locking portion 11.

In the above embodiment, the elongated hole 12 was formed in the main frame 1 and the shaft part 16 was provided in the bottom cover body 13 to rotatably and freely support the bottom cover body 13. , and the bottom cover body 1
It is also possible to form an elongated hole 12 in 3 so that the bottom cover body 13 can be rotatably and movably supported.

Further, in the above embodiments, a roaster has been described, but the invention is not limited to roasters, and can be applied as a bottom cover device for various types of cooking appliances that are formed into a housing shape, have a reflective plate, and have an opening. .

According to the present invention, the retaining part formed at one end of the bottom cover body which is pivotally supported in a rotatable and movable manner is engaged with the locking part formed at one end part of the opening closed by the bottom cover body. Since the bottom cover is energized by a reflector to hold the bottom cover, the closed state of the bottom cover can be maintained without using parts such as springs, the number of parts is reduced, ease of assembly is improved, and The bottom cover is in contact with the reflective plate, so there is no gap in the opening, there is no risk of dust entering, and it can be opened and closed easily.
