As shown in fig. 1 to 12, a cooking apparatus 100, such as a microwave oven, according to an embodiment of the present invention includes a body 1 and a door 2.

Specifically, referring to fig. 1, the front side of the body 1 is open, and the door body 2 is provided at the front side of the body 1 to open and close the body 1. Here, it should be noted that the direction "front" may be understood as a direction facing the user, and the opposite direction is defined as "rear", i.e., a direction away from the user. When the microwave oven is used, the door body 2 is opened firstly, a user can put articles to be cooked, such as food and the like, into the body 1 from the front side of the body 1, then the door body 2 is closed, and then the cooking device 100, such as a microwave oven, is started to cook the food put into the body 1. After cooking is finished, the door body 2 is opened, and the food in the body 1 is taken out.

The upper portion of the body 1 is provided with a support seat 12 having a first pivot hole 1232, and a first engagement plate 13 having a first pivot shaft 131 at one end (e.g., a rear end in fig. 2 and 3) pivotably engaged in the first pivot hole 1232 with a rotation axis extending in the front-rear direction and a second pivot hole 1331 at the other end (e.g., a front end in fig. 2 and 3). For example, in the example of fig. 1 to 3, the body 1 may include an outer cover and a main body 11 disposed in the outer cover, the support base 12 may be disposed on the top of the main body 11 between the outer cover and the main body 11, in which case the support base 12 is hidden in the outer cover to make the appearance of the entire cooking apparatus, such as a microwave oven, beautiful, the central axis of the first pivot hole 1232 extends in the front-rear direction to cooperate with the first pivot shaft 131 whose rotation axis extends in the front-rear direction, and the first pivot shaft 131 is rotatable about the rotation axis of the first pivot shaft 131 with respect to the first pivot hole 1232, so that the first cooperation plate 13 may be rotated. Optionally, the first pivot shaft 131 extends horizontally in the front-to-rear direction.

The lower part of the body 1 is provided with a second matching plate 14 extending forwards, and a limiting groove 141 is formed on the second matching plate 14. For example, in the example of fig. 8 and 9, the bottom of the body 1 has a bottom plate 16, the second fitting plate 14 may be provided on the upper surface of the bottom plate 16, and the front end of the second fitting plate 14 projects forward of the front surface of the bottom plate 16, and a stopper groove 141 is formed at the front end of the second fitting plate 14.

The upper portion of the door body 2 is provided with a second pivot shaft 22, the rotation axis of which extends along the vertical direction and is pivotally matched in the second pivot hole 1331, the lower portion of the door body 2 is provided with a third pivot shaft 23, the pivot axis of which extends along the vertical direction, and the rotation axis of the second pivot shaft 22 and the pivot axis of the third pivot shaft 23 are coaxially arranged. A connecting limiting plate 24 is arranged between the lower part of the door body 2 and the second matching plate 14, the connecting limiting plate 24 is pivotally connected with the third pivot shaft 23, and a limiting structure 241 separably matched with the limiting groove 141 is arranged on the connecting limiting plate 24. The door body 2 is adapted to rotate about the rotational axis of the second pivot shaft 22 and the pivotal axis of the third pivot shaft 23 to open and close the body 1 when the check structure 241 is fitted in the check groove 141, and the check structure 241 is disengaged from the check groove 141 to open and close the body 1 when the door body 2 rotates about the rotational axis of the first pivot shaft 131.

For example, in the example of fig. 1 to 3, the door body 2 may include a door cover and a door main body 21 provided in the door cover, the second pivot shaft 22 is provided at the top of the door main body 21, the third pivot shaft 23 is provided at the bottom of the door main body 21, the second pivot hole 1331 may be a through hole penetrating the first fitting plate 13 in the up-down direction, the second pivot shaft 22 is rotatably fitted in the second pivot hole 1331 of the first fitting plate 13, the second pivot shaft 22 is rotatable about the rotation axis of the second pivot shaft 22 with respect to the second pivot hole 1331, the third pivot shaft 23 is rotatable about the pivot axis of the third pivot shaft 23 with respect to the connection limiting plate 24, when the limiting structure 241 is fitted in the limiting groove 141, the connection limiting plate 24 is stationary with respect to the second fitting plate 14, and by arranging that the rotation axis of the second pivot shaft 22 and the rotation axis of the third pivot shaft 23 are coincident, the door body 2 may be swung in a side-pulling manner about the rotation axis of the second pivot shaft 22 and the pivot axis The body 1 is opened and closed, which is a conventional side-opening type door.

In the process that the door body 2 rotates around the rotation axis of the first pivot shaft 131, the door body 2 rotates upwards, the limiting structure 241 gradually disengages from the limiting groove 141, and after the limiting structure 241 completely disengages from the limiting groove 141, the door body 2 continues to rotate upwards, and most of the opening at the front side of the body 1 can be exposed, so that food can be put in or taken out, as shown in fig. 1. From this, through adopting this brand-new mode of opening the door, greatly reduced the door body 2 when opening and the normal direction distance between the user, avoided traditional mode of opening the door to the restriction in normal direction space to a certain extent to and the risk of colliding with that leads to the fact the user, bring the door body 2 that opens the door that the user is different simultaneously and test, increased the interest that the user opened the door body 2 and tested.

It should be noted that, when the manner of opening the door body 2 upward is adopted, the door body 2 may be rotated by a certain angle around the rotation axis of the second pivot shaft 22 and the pivot axis of the third pivot shaft 23, and then the door body 2 may be rotated upward around the rotation axis of the first pivot shaft 131 to fully open the front-side opening of the body 1. In this way, while the normal distance between the door 2 and the user when opening is ensured to be reduced, the phenomenon that the door 2 directly rotates upwards around the rotation axis of the first pivot shaft 131 to interfere with other parts of the body 1, such as a control panel and the like, can be avoided.

According to the cooking device 100, such as a microwave oven, compared with the traditional side-pull type, pull-down type and door opening modes, the normal distance between the door body 2 and a user when the door body is opened can be reduced, the limitation of the traditional door opening mode on the normal space and the collision risk caused to the user are avoided to a certain extent, meanwhile, the different door opening 2 tests are brought to the user, and the interestingness of the door opening 2 test of the user is increased.

Referring to fig. 2-3 in conjunction with fig. 4 and 5, the support base 12 includes, in accordance with some embodiments of the present invention: a connecting portion 121 and an extending portion 122, the connecting portion 121 is connected to the upper portion of the body 1, one end (e.g., the lower end in fig. 2 and 3) of the extending portion 122 is connected to the connecting portion 121, the other end (e.g., the upper end in fig. 2 and 3) of the extending portion 122 extends toward a direction away from the center of the body 1, the other end of the extending portion 122 is provided with a pivot cylinder 123 with an open front side, a front end side wall of the pivot cylinder 123 is provided with a first blocking rib 1233 extending forward, the first pivot shaft 131 is pivotably fitted in the pivot cylinder 123, and an outer peripheral wall of the first pivot shaft 131 is provided with a second blocking rib 1311 adapted to be blocked against the first blocking rib 1233 in a rotation direction around a rotation axis of the first pivot shaft 131. Therefore, by arranging the first blocking rib 1233 and the second blocking rib 1311, the rotation angle of the door body 2 around the rotation axis of the first pivot shaft 131 can be limited to ensure an optimal rotation opening angle.

For example, in the example of fig. 2 to 5, the connection part 121 may be formed as a plate, and the connection part 121 may be fixedly coupled to the top of the main body 11 by a threaded fastener such as a screw, etc., so that the support base 12 is coupled to the body 1 by the connection part 121. The extension portion 122 extends vertically upward, and a lower end of the extension portion 122 is connected to a left end of the connection portion 121. A pivot cylinder 123 is attached to the upper end of the extension 122. By providing the pivot cylinder 123 with its front side open, the first pivot shaft 131 can be easily installed into the pivot cylinder 123 from the front side of the pivot cylinder 123. The first stopper rib 1233 is provided on the front end surface of the pivot cylinder 123 and extends forward, and the second stopper rib 1311 may be a square protrusion provided on the outer peripheral wall of the first pivot shaft 131, but is not limited thereto. In the process that the door body 2 rotates upward along with the first pivot shaft 131 around the rotation axis of the first pivot shaft 131, the second blocking rib 1311 rotates along with the first pivot shaft 131 and gradually approaches the first blocking rib 1233 until the second blocking rib 1233 stops, so that the limiting effect is achieved. Alternatively, the first rib 1233 is integrally connected to the pivot cylinder 123 by welding, bonding or integral machining, and the second rib 1311 is integrally connected to the first pivot 131 by welding, bonding or integral machining.

It can be understood that, since different types of cooking devices 100, such as the door 2 and the body 1 of a microwave oven, have different sizes, and the optimal rotation opening angle is correspondingly different, the specific positions of the first blocking rib 1233 and the second blocking rib 1311 need to be determined according to the actual model size of the cooking device 100, such as the microwave oven.

Alternatively, as shown in fig. 2-3 and 5, the first barrier rib 1233 is located below the side of the central axis of the pivot cylinder 123 away from the connecting portion 121. For example, referring to fig. 2 and 3 in combination with fig. 5, the first blocking rib 1233 is located on the left side of the central axis of the pivot cylinder 123, and the first blocking rib 1233 is located below the central axis of the pivot cylinder 123, at this time, the angle of rotation of the door body 2 around the rotation axis of the first pivot shaft 131 may be an obtuse angle, the door body 2 may open most of the front side opening of the body 1 relative to the body 1, or completely open the front side opening of the body 1, thereby further facilitating the user to put in or take out food, meanwhile, through the stopping action of the first blocking rib 1233 and the second blocking rib 1311, the weight of the entire door body 2 may be supported on the first blocking rib 1233, and after the door body 2 is opened, the user does not need to hold the door body 2 by hand.

Further, the second rib 1311 is adapted to abut against the front end surface of the pivot cylinder 123, as shown in fig. 2. Thus, the second rib 1311 can serve as a limit, and the first pivot shaft 131 can be fitted in the pivot cylinder 123 to a proper length.

According to some embodiments of the present invention, referring to fig. 2-3 in combination with fig. 4-7, the front end of the body 1 has a front plate 15, the top of the front plate 15 has a first front plate portion 151 and a second front plate portion 152 connected to each other, the first front plate portion 151 has a height lower than that of the second front plate portion 152, and the height difference between the first front plate portion 151 and the second front plate portion 152 is h, wherein the first mating plate 13 is located at the first front plate portion 151, and the first mating plate 13 includes: a curved plate 132 and a connecting plate 133, wherein a rear end of the curved plate 132 is connected to a sidewall of the first pivot shaft 131 and extends forward in a direction away from the first pivot shaft 131, the connecting plate 133 extends in a left-right direction, one end of the connecting plate 133 is connected to the curved plate 132, and the other end of the connecting plate 133 is formed with a second pivot hole 1331, wherein a distance between a rotation axis of the first pivot shaft 131 and a farthest point of the curved plate 132 is l, and l, h satisfy: l is less than or equal to h. Therefore, the distance l is not larger than the height difference h, the rotating space of the first matching plate 13 can be well ensured, and the first matching plate 13 cannot interfere with the outer cover when rotating.

For example, in the example of fig. 2 to 7, the first front plate portion 151 and the second front plate portion 152 are sequentially connected from left to right, the length of the first front plate portion 151 is smaller than that of the second front plate portion 152, and the first front plate portion 151 is located below the second front plate portion 152, so that the support base 12 and the first fitting plate 13 can be disposed at the first front plate portion 151, making the appearance of the entire cooking apparatus 100, such as a microwave oven, beautiful. The rear end of the curved plate 132 is connected to the front side wall of the first pivot shaft 131 and extends in a forward bending manner, the connecting plate 133 extends substantially in the left-right direction, one end of the connecting plate 133 is connected to the front end of the curved plate 132, the other end of the connecting plate 133 is pivotably connected to the second pivot shaft 22 through the second pivot hole 1331, and the first pivot shaft 131 and the second pivot hole 1331 are located on the same side (for example, the left side in fig. 2) of the first fitting plate 13, so that the space occupied by the first fitting plate 13 in the length direction of the door body 2 can be reduced, and in the process that the door body 2 rotates around the rotation axis of the first pivot shaft 131, the distance between the door body 2 and the first pivot shaft 131 is relatively short, and the door body 2 can rotate in place more smoothly. When the door body 2 rotates around the rotation axis of the first pivot shaft 131, the first fitting plate 13 can rotate around the rotation axis of the first pivot shaft 131 together with the door body 2, and by setting the distance l between the rotation axis of the first pivot shaft 131 and the farthest point of the curved plate 132 to be not more than the height difference h between the first front plate portion 151 and the second front plate portion 152, the first fitting plate 13 can be better accommodated in the space defined between the first front plate portion 151 and the second front plate portion 152, and is not easily interfered with the outer cover.

Alternatively, referring to fig. 6 in combination with fig. 7, a concave portion 1511 recessed downward is formed on the first front plate portion 151, and the shape of the concave portion 1511 is adapted to the shape of the first pivot shaft 131. For example, as shown in fig. 6 to 7, the recessed portion 1511 is a groove formed on the upper surface of the first front plate portion 151, the groove penetrating the front surface and the rear surface of the first front plate portion 151 in the front-rear direction so as to be able to fit the first pivot shaft 131 for rotation about the rotation axis of the first pivot shaft 131, and the first fitting plate 13 does not interfere with the front plate 15 when rotating.

Alternatively, as shown in fig. 2 to 5, the pivot cylinder 123 includes two sub-pivot cylinders 1231 arranged at a distance from each other in the front-rear direction and having both front and rear ends open, the other end of the extension 122 is provided with two extension arms 1221 arranged at a distance from each other in the front-rear direction, the free ends (e.g., the left end in fig. 5) of the two extension arms 1221 are respectively provided with one sub-pivot cylinder 1231, and the rear end of the first pivot shaft 131 is fitted into the two sub-pivot cylinders 1231. Therefore, the structure is simple, the realization is easy, the material is saved, and the cost is reduced.

The rear end of the first engaging plate 13 is designed in the form of a first pivot shaft 131, and is in clearance fit with the first pivot hole 1232 on the support base 12, so that the first engaging plate 13 can rotate around the rotation axis of the first pivot shaft 131, and the second pivot hole 1331 at the front end of the first engaging plate 13 is also in clearance fit with the second pivot shaft 22 on the door body 2. The upper portion of the door body 2 may be provided with a first door shaft plate 25, the second pivot shaft 22 may be fixedly connected with the first door shaft plate 25 into a whole in a welding or interference fit manner, and the first door shaft plate 25 is welded to the door body 2. The above matching mode is to ensure that the door body 2 can rotate around the rotation axis of the second pivot shaft 22 in the side-pulling state; in the upward rotation open state, the door body 2 can rotate about the rotation axis of the first pivot shaft 131.

According to some embodiments of the present invention, referring to fig. 8 in combination with fig. 9 to 11, the limiting groove 141 penetrates the second matching plate 14 in the up-down direction, and the limiting groove 141 penetrates a side surface of the second matching plate 14 adjacent to the center of the door body 2, the limiting structure 241 includes a limiting portion 2411 connected to the connection limiting plate 24 and extending downward from the connection limiting plate 24, and a buckling portion 2412 connected to a lower end of the limiting portion 2411, when the limiting structure 241 is matched with the limiting groove 141, the limiting portion 2411 is matched in the limiting groove 141, the buckling portion 2412 is located below the second matching plate 14, and the upper surface is adapted to contact with the bottom surface of the second matching plate 14.

Specifically, the end of the connection limiting plate 24 has a limiting structure 241, which is matched with the limiting groove 141 of the second matching plate 14, when the door body 2 is in the side sliding door opening state, the connection limiting plate 24 and the second matching plate 14 are matched and connected with the limiting groove 141 through the limiting structure 241, at this time, the connection limiting plate 24 cannot rotate or move, and the door body 2 can rotate around the rotation axis of the second pivot shaft 22 and the pivot axis of the third pivot shaft 23, so as to complete the operation of the side sliding door. When the upward rotation opening state is adopted, the third pivot shaft 23 on the door body 2 drives the connection limiting plate 24 to be separated together, at the moment, the limiting structure 241 on the connection limiting plate 24 is separated out of the limiting groove 141 of the second matching plate 14 and rotates around the rotation axis of the first pivot shaft 131 together with the door body 2, after the door body 2 is rotated to be opened, the door body 2 can rotate around the rotation axis of the first pivot shaft 131 in the original way, the limiting structure 241 connected with the limiting plate 24 returns to the limiting groove 141 of the second matching plate 14 again, and at the moment, the door body 2 can be restored to the lateral opening and closing state.

Optionally, as shown in fig. 8 to 11, there are two limiting grooves 141, two limiting grooves 141 are arranged at intervals in front of and behind, and two limiting structures 241 are adapted to be matched with the two limiting grooves 141 in a one-to-one correspondence manner. Therefore, the structure is reliable, and the cost is low.

The connecting limit plate 24 and the second matching plate 14 are matched and connected with the limit groove 141 through a limit structure 241, and the second matching plate 14 is fixed on the bottom plate 16. The lower part of the door body 2 is provided with a second door shaft plate 26, the second door shaft plate 26 can be fixedly connected to the door body 2 in a welding mode, one end (for example, the upper end in fig. 8) of the third pivot shaft 23 can be fixedly connected with the second door shaft plate 26 into a whole in a welding or interference fit mode, the other end (for example, the lower end in fig. 8) of the third pivot shaft 23 is in clearance fit with the connection limiting plate 24, and the one end of the third pivot shaft 23 can be limited in a press riveting mode so as to ensure that the connection limiting plate 24 of the door body 2 cannot generate axial movement in the opening and closing process.

In the example of fig. 1 to 12, the first pivot shaft 131 to the third pivot shaft 23 are all arranged on the left side of the door body 2. Of course, those skilled in the art will understand that the first pivot shaft 131 to the third pivot shaft 23, etc. may also be disposed on the right side of the door body 2.
