Description

[Detailed Description of the Invention] The present invention relates to a lid locking device for a bottom lid plate of a cooking appliance such as a toaster, and relates to a structure that reduces contact resistance when opening and closing the lid.

The conventional lid locking device for this type of cooker has a spring locking piece fixed to the inner surface of the lid with rivets, and a locking piece bent at the tip of the spring locking piece is attached to the opening. A structure was adopted in which elasticity was used to releasably engage a retaining portion formed on the edge of the retainer.

This conventional structure has the disadvantage that the contact resistance between the locking piece part of the spring locking piece and the locking part is large, and a large force is required for opening/closing operations.

In addition, conventionally, the lid had a structure in which an operating knob for opening and closing was attached separately and independently to the outer surface of the lid, so a spring locking piece and a knob had to be attached to the lid. , the number of parts was large, and assembly workability was poor.

The present invention was developed in view of the above-mentioned drawbacks, and a protrusion is provided on the locking piece of the locking member to reduce the contact resistance between the locking piece and the locking part when opening and closing the lid, thereby ensuring smooth opening and closing. To provide a lid locking device for a cooker that can be assembled easily by reducing the number of parts and improving ease of assembly.

The structure of the present invention is such that the lid body is provided at the opening of the cooking device body so as to be openable and closable, and one end of the lid body is provided with an elastic locking piece formed by a protruding bent part that is locked by a locking part formed in the opening. A locking member is provided on one side and integrally formed with a knob projecting to the outside of the lid body on the other end side, and a protrusion is provided on the top of the protrusion of the locking piece of the locking member. It is what it is.

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

Reference numeral 1 denotes a main body of the cooking device, and an entrance/exit 2 is opened in the front for taking roasted items in and out of the roasting chamber 4. This entrance/exit 2 has an opening/closing lid body 6 equipped with a see-through glass 5 through which the roasting chamber 4 can be viewed. is provided so that it can be opened and closed freely.

Further, an opening 7 that opens to the bottom of the roasting chamber 4 is formed on the bottom surface of the main body 1, and a locking portion 8 that is bent inward is formed on the front edge of this opening 7. ing.

Further, the rear edge of the lid 9 is rotatably attached to the rear edge of the opening 7.

Further, a protrusion 10 that bulges inward is formed at the front end of the lid 9, and an insertion hole 11 is formed in the front end surface of the protrusion 10.

Next, reference numeral 12 denotes a locking member, which is made of an elastic plate material, and has an elastic locking piece 13 formed at one end thereof at a protruding bent portion bent in a substantially doglegged shape.

A projection 15 is provided at the top of the projection 14 of the elastic locking piece 13.
are installed on both the left and right sides.

Further, an inclined stepped part 16 is formed in the middle part of this locking member 12 and is inserted and held in the insertion hole 24 of the protruding part 14, and the other end part is formed by bending at a right angle and having a curved tip. A knob 17 is integrally formed.

This locking member 12 is connected to the insertion hole 1 of the protrusion 10 of the lid body 9.
1 from the outside, the stepped portion 16 is positioned in the insertion hole 24 portion, and the intermediate portion that abuts the inner surface of the lid body 9 is fixed with a rivet 23.

In this state, the locking piece 13 of the locking member 12 is projected inward on the front end side of the lid 9, and the knob 17 is positioned outside the lid 9 and fixed to the lid 9.

Further, a grilling grate 18 that can be inserted and removed from the entrance/exit 2 is removably supported in the roasting chamber 4 of the main body 1.
Electric heaters 19 are provided in the roasting chamber 4 above and below the roasting chamber 8, respectively.

A timer adjustment knob 20 for controlling the heater 19 is provided on the front side of the main body 1.

Further, the opening/closing lid body 6 is provided with a handle 21, and furthermore, grip knobs 22 are provided on both sides of the main body 1.

Next, the operation of this embodiment will be explained.

When the lid 9 is rotated with the knob 17 of the locking member 12 when closing the opening 7 on the bottom surface of the main body 1 with the lid 9, the protrusion 14 of the locking piece 13 of the locking member 12 is rotated. When the locking portion 8 is slid and the protrusion 15 of the protrusion 14 passes over the locking portion 8, a feeling of moderation is felt, and since the protrusion 14 slides in engagement with the protrusion 15, there is little contact resistance. , occlusion operation can be done easily.

Further, due to the contact between the protrusion 15 of the projection 14 of the locking piece 13 and the edge of the locking part 8, the engagement between the locking piece 13 and the locking part 8 is released due to vibration, impact, etc. It never comes off.

In this state, the object to be roasted is placed on the grill 18 and the heater 1
Roasting can be performed by applying electricity to 9.

When cleaning the roasting chamber 4, etc., when the lid 9 is pulled with the knob 17, the protrusion 15 comes into contact with the locking piece 13 of the locking member 12 as it slides into contact with the edge of the locking part 8. However, the contact resistance is low and the lid 9 can be opened easily.

In addition, in the above embodiment, the bottom lid body 9 was explained, but
It can be applied not only to the lid 9 at the bottom but also to the lids at each opening.

Furthermore, the number of protrusions 15 on the locking member 12 is not limited to two, and may be one or more, and may be formed as appropriate depending on the width of the locking member 12.

According to the present invention, since the protrusion is formed on the top of the protrusion of the locking piece formed on the locking member of the lid that is locked with the locking portion formed in the opening of the cooker main body, the lid The contact resistance between the locking part and the protruding part of the locking piece is reduced when opening/closing the lid, allowing easy opening/closing with light operating force, and the protrusion feels moderate when closing the lid, ensuring secure closure. In addition, there is no risk of the lid accidentally opening due to vibration or impact due to contact between the protrusion and the locking part, and since the grip is integrally formed on the locking member, there are fewer parts and assembly is easier. This improves work efficiency.
