Description

Technical Field

[0001] The utility model relates to the field of household appliances, in particular to a cooking utensil capable of preventing a user from missing an inner cover, such as an electric rice cooker, a micro-pressure electric rice cooker, an electric steamer, a pressure electric steamer and the like. Background Art

[0002] With the improvement of living standards, rice cookers and other cooking appliances have become indispensable appliances in modern family kitchens. In order to facilitate cleaning, the upper covers of these cooking appliances are often designed to be detachable. However, this design also brings a problem: after removing the upper cover for cleaning, users sometimes forget to reinstall the upper cover, resulting in incomplete cooking of food during cooking, and may even cause safety hazards.

[0003] In order to solve this problem, a variety of solutions have been proposed in the existing technology. For example, the utility model patent with patent number CN201189077Y realizes the detachable cover body through a push button structure, and uses the elastic recovery of the push button structure to prevent the cover from buckling when it is not installed. However, this method adds a push button structure, which increases the number of parts and costs, and also reduces the assembly efficiency of the product. Although the patent document with patent number CN203873593U also realizes the detachable upper cover and solves the problem of missing installation, the anti-fool structure set therein also increases the complexity and cost of the product.

[0050] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0051] Embodiment 1:

[0052] See also Figure 1 — Fig. 9 The utility model provides a cooking utensil for preventing the inner cover from being missed; the cooking utensil comprises a main body 1, a cover body 2 and a buckle device.

[0053] The cover body 2 has a detachable inner cover 21 , and the buckle device includes a buckle plate 27 and a buckle seat 11 . The buckle plate 27 is coupled to the cover body 2 in a manner of rotating around a fixed axis, and the buckle seat 11 is fixed to the body 1 .

[0054] Since the inner cover 21 is detachable relative to the cover body 2 , the cover body 2 can be easily cleaned.

[0055] The inner cover has an actuating portion adapted to abut against the pinch plate, and the actuating portion is configured to drive the pinch plate to rotate from a first position to a second position;

[0056] A first elastic member is disposed between the gusset plate and the cover body, and the first elastic member applies force to the gusset plate to make it tend to rotate from the second position to the first position;

[0057] Wherein, the first position is configured such that the buckle plate abuts against the buckle seat, thereby preventing the cover from buckling with the body;

[0058] Wherein, the second position is configured so that the buckle plate can be snapped into the buckle seat, thereby allowing the cover body to be snapped into the main body.

[0059] In some embodiments, the cooking utensil includes an electric rice cooker, a micro-pressure electric rice cooker, an electric steamer, or a pressure electric steamer.

[0060] In the utility model, the actuating part 211 is arranged on the inner cover 21, which cooperates with the buckle plate 27, so that the buckle plate 27 takes the rotating shaft 272 as the axis, and switches between the buckled position and the foolproof position through the different elastic states of the first elastic member 271. The indications in different states are clear and there will be no misoperation. It is easy to use and has a simple structure, reducing the number of assembly parts.

[0061] In some embodiments, one end of the first elastic member abuts against the cover body, and the other end abuts against the gusset plate. In some preferred embodiments, the first elastic member is a torsion spring installed on the shaft, one leg of which abuts against the cover body, and the other leg abuts against the gusset plate. The torsion spring used here is an "L" type torsion spring, see Figure 6 The torsion spring on the buckle plate 27.

[0062] See also Figure 4 In some embodiments, the cover body 2 is provided with a shaft seat 25, which is used for assembling the shaft. The shaft seat is integrally formed with the cover body, and the shape is easy to manufacture.

[0063] In some embodiments, the inner cover 21 includes an inner cover frame 212 , an inner cover body 213 and a sealing ring 214 ; the inner cover body is installed on the inner cover frame, and the sealing ring 214 is installed on the inner cover frame 212 ; wherein the actuating portion 211 is arranged on the inner cover frame 212 .

[0064] In this embodiment, the inner cover frame is a ring frame, and the inner cover body is connected to the inner cover frame by snapping; the sealing ring is first installed on the inner cover frame, and then the inner cover body presses the sealing ring on the inner cover frame when snapping with the inner cover frame.

[0065] The inner cover body serves as a condensation plate, and the sealing strip is arranged around the inner cover body. After the electric rice cooker is used, it can be removed from the cover body and directly cleaned, which facilitates the cleaning of the electric rice cooker and ensures the sealing effect when it is used next time.

[0066] There is no limitation on the detachable manner between the inner cover and the cover body, and it can be set according to the actual situation.

[0067] In some embodiments, see Fig. 9 As shown, a button is provided on the cover body 2, and the button is configured to drive the buckle plate 27 to rotate from the second position to the third position; wherein the third position is configured so that the buckle plate is disengaged from the snap connection with the buckle seat, thereby releasing the buckling state between the cover body and the main body.

[0068] In some embodiments, the button includes a button body 22, a button hole 23 and a second elastic member 24, and the button body slides in the button hole to apply force to the buckle plate; the second elastic member is arranged between the button body and the cover body, and applies force to the button body in the opposite direction of the force applied by the button body to the buckle plate.

[0069] In order to facilitate operation, a key matching portion 273 is provided on the buckle plate 27. The key matching portion 273 is provided together with the buckle plate, which has a simple structure, few parts, and is easy to assemble. The specific structure is as follows: the buckle plate 27 also includes a key matching portion 273, and the key matching portion 273 is used to change the buckle plate 27 from the buckling position I to the unlocking position III.

[0070] The second actuating mating portion 273 at the top is subjected to pressure to rotate the buckle plate to exert force on the first elastic member 271, allowing the elastic deformation occurring at the second position I to continue and separate the buckle plate 27 from the buckle seat 11 to the unlocking position III at the first position to release the buckle between the cover body 2 and the main body 1.

[0071] See also Fig. 9 As shown, since the locking position I and the foolproof position II are in opposite directions, and the unlocking position III is to continue the opposite operation of the foolproof position II at the locking position I, it is easy for the operator to understand without being misled, and is especially suitable for use by the elderly.

[0072] The second elastic member 24 is mainly used to restore the button body 22 to prevent the button body 22 from sinking into the button hole 23 and becoming inoperable.

[0073] In the utility model, the buckle plate is switched to different positions through the cooperation of the actuating part, the rotating shaft and the elastic part, so that the cover body and the main body can be switched between the anti-foolproof and buckled positions. The operation is simple and the consumers can use it safely and reliably. At the same time, the buckle plate is also provided with a button cooperation part 273 for cooperating with the button to unlock. The structure is compact and reasonable, and the operation is also simple.

[0074] Embodiment 2

[0075] See also Figure 5 , Figure 6 , Figure 7 and Figure 8 , different from the first embodiment, in this embodiment, for further safety in use, it also includes an indication component for the cover body and the main body to be snapped into place, which includes a slide groove 276, a slider 274 and a third elastic member 275; wherein, the slide groove 276 is arranged on the buckle plate 27; the slider 274 slides in the slide groove 276; the third elastic member 275 abuts between the cover body 2 and the slider 274, and is compressed by the slider 274 when the buckle plate 27 is converted from the first position to the second position, and is released when the cover body 2 and the main body 1 are snapped together so that the slider 274 abuts against the buckle seat 11 and makes a sound to indicate that the buckle is in place.

[0076] When the buckle plate 27 is switched from the first position (the foolproof position for preventing the buckle without the inner cover installed) II to the second position I (the buckle position for buckling the cover and the main body), the slider 274 compresses the third elastic member. This is mainly because the slider is blocked by the actuating portion 211 during the buckle process of the cover and the main body. The slider 274 has an upward sliding motion relative to the slide groove 276, and at this time, the third elastic member 275 is compressed. When the cover and the main body are buckled, the buckle plate 27 has a counterclockwise rotation (please refer to Fig. 9 ), at this time, the slider moves horizontally along with the buckle plate for a certain distance and is free from the obstruction of the actuating portion 211, and the third elastic member releases and pushes the slider to slide downward relative to the slide groove and just abut against the upper edge of the buckle seat 11, making a sound to remind the user that the cover body 2 and the main body 1 are buckled.

[0077] In some embodiments, a guide surface 2111 is disposed on the actuating portion 211, and the guide surface 2111 allows the slider 274 to escape from the blocking of the actuating portion 211 in a predetermined direction. Preferably, a guided surface in the same direction as the guide surface is disposed on the lower surface of the slider, so that when the actuating portion blocks the slider, the friction between the guide surface and the guided surface is relatively large, and the blocking is effective; when the snap-in space is released, during the release of the third elastic member, the elastic force pushes the slider down, ensuring that the slider quickly works in place and makes a sound.

[0078] In this embodiment, the actuating portion on the removable inner cover can cooperate with the buckle plate and the snap-in-place indicator assembly. The structural design is ingenious and reasonable, avoiding damage to the rice cooker caused by excessive pressure on the cover.

[0079] See also Figure 7As shown, a protruding block 26 is provided on the cover body 2 in the middle of the rotating shaft seat 25, which is used to abut against the upper end of the third elastic member 275. Preferably, a positioning column adapted to the third elastic member is provided on the lower surface of the protruding block 26.

[0080] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
