Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to an attachment/detachment device for the exterior body of an electric cooking device such as a hot plate to prevent burns caused by tentacles touching the hot plate. This measure was used to wash the exterior body soiled with boiling water, etc.

(Prior art and problems) Conventionally, the exterior body of a cooking utensil is screwed to studs, etc. provided on the outer bottom surface of the heating plate for cooking, so when washing the exterior plate soiled with boiling liquid during cooking, etc. In this case, the screws had to be removed and the screws had to be tightened again after washing with water, which was a tedious task.Therefore, the leakage could only be wiped with a cloth or the like, and a sufficient cleaning operation could not be carried out.

(Means for solving the problem) The present invention solves the above-mentioned drawbacks and makes it possible to attach and detach the exterior plate with a one-touch operation. A locking body that is normally displaced to a locking position is slidably provided,
Inside the outer casing of the cooker, the upper end is joined to the outer casing,
A locking plate having a locking hole that engages with the locking pawl of the locking body is provided below, and a U-shape is provided between the locking plate and the exterior body to urge the locking plate toward the exterior body. The reason is that a leaf spring is inserted.

(Example) Fig. 1 is an exploded perspective view of the attaching/detaching device, Fig. 2 is a left vertical cross-sectional view cut in the center showing the mounting process of the exterior body, and Fig. 3 is a left longitudinal cross-sectional view cut in the center showing the mounting state of the external body. It is.

In Fig. 1, reference numeral 1 denotes a support frame for the cooking device, which includes a connecting arm 1a, a parallel arm 1b bent from both ends of the connecting arm 1a and extending in parallel, and a supporting frame 1 that is bent outward from the tip of the parallel arm 1b. The connecting arm 1a is provided with a groove _1a1 , and the leg and arm 1c is provided with a leg 2.

As shown in FIG. 2, the supporting arm 1 has its legs 1c fixed to studs B provided on the outer bottom surface of the cooking hot plate A with screws D with a collar C interposed therebetween.

Reference numeral 3 denotes a locking body, which includes an upper plate 3a having a locking claw _3a1 at the tip, and a rear plate 3 hanging from the rear end of the upper plate 3a.
b, a lower plate 3c extending parallel to the upper plate 3a from the rear plate 3b, and an operating section 3 extending from the lower plate 3c.
d, and a slit _3c1 is provided in the longitudinal direction on the center line in the width direction of the lower plate 3c.

As shown in FIG. 2, the locking body 3 sandwiches the connecting arm 1a of the support frame 1 between its upper plate 3a and lower plate 3c, and can slide on the connecting arm 1a as described later. It is composed of

Reference numeral 4 denotes a guide plate for regulating the sliding of the locking plate 3, and a flat portion 4a that comes into contact with the outer surface of the lower plate 3c of the locking body 3.
and an upright portion 4b formed by bending the rear end of the flat portion 4a.

The flat portion 4a of the guide plate 4 is fixed to the connecting arm 1a of the support frame 1 by means of a screw 5 into which a slit _3c1 formed in the lower plate 3c of the locking plate 3 is loosely inserted.

Therefore, the locking body 3 is made slidable while being guided by the screw 5 which is loosely inserted into the slit _3c1 .

A coil spring 6 is interposed between the rear plate 3b of the locking body 3 and the upright portion 4b of the guide plate 4, and presses the locking body 3 to normally displace it to the locking position.

As shown in FIG. 2, 7 is an exterior body surrounding the cooking hot plate A, and the upper end of a locking plate 7a is joined to the exterior body 7 in a manner corresponding to the mounting position of the locking body 3.
A locking hole 7a 1 that engages with the locking claw 3a ₁ of the locking plate 3 is bored below the locking plate _7a .

A U-shaped leaf spring 8 is interposed between the exterior body 7 and the locking body plate 7a ₁ to bias the locking plate 7a ₁ toward the exterior body 7.

In addition, although it is sufficient to provide this attachment/detachment device in one location of the cooking appliance, it may be provided in two locations facing each other.

(Function) (a) When the exterior body 7 is detached As shown in FIG. 2, the coil spring 6 whose one end abuts against the upright portion 4b of the guide plate 4 fixed to the connecting arm 1a of the support frame 1 Due to the extension force, the locking body 3 is guided by the screw 5 loosely inserted through the slit _3c1 , and the rear plate 3b is brought into contact with the rear wall surface of the connecting arm 1a.

(b) When attaching the exterior body 7 As shown in FIGS. 2 and 3, when the exterior body 7 is pushed down from above, the bent portion of the U-shaped leaf spring 8 comes into contact with the connecting arm 1a. By deforming, the locking plate 7
The lower part of the locking plate 7a is pushed inward (the lower end of the locking plate 7a moves in the groove _1a1 formed in the connecting arm 1a), and the locking hole _7a1 aligns with the inclined surface of the locking claw _3a1 . Climb over and lock it on the rear.

After the locking hole 7a is locked with the locking pawl _3a1 , the locking plate 7a is pulled back toward the exterior body 7 by the restoring force of the U-shaped leaf spring 8, and the locking plate 7a is pulled back toward the exterior body 7, and the locking hole _7a1 is pulled back toward the exterior body 7. The locking of the locking claw _3a1 is established.

As described above, the exterior body is attached and locked by the simple operation of pushing down at the normal position.

(c) When detaching the exterior body 7 (releasing the lock) As shown in FIG.
With the locking pawl _3a1 locked in the locking hole _7a1 , the locking plate 7a is displaced counterclockwise against the U-shaped leaf spring 8. Therefore, the position of the locking hole 7a ₁ is displaced upward and the engagement with the locking claw 3a ₁ is released.

As described above, the exterior body can be unlocked and removed by simply pushing the locking body.

(Effects) The present invention can be installed with a simple operation of pushing down the exterior body at the normal position, and can be detached with a simple operation of pushing in the locking body, so-called The cooking device has the effect that the exterior body can be attached and detached with a one-touch operation, and is therefore extremely convenient when washing the exterior body with water.
