Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen appliances, in particular to a cooking device. BACKGROUND

[0002] In recent years, with the development of cooking devices towards high-end and specialization, users' requirements for air tightness, safety and use experience of products are increasingly improved. In order to ensure the air tightness of the cooking cavity, the door body usually needs to be configured with a larger hinge force, but this also leads to too much resistance when the user manually opens the door, and the common problem of "difficulty in pulling the door handle" occurs.

[0003] To solve this contradiction, the existing technology proposes a push rod motor automatic door opening scheme, which replaces manual operation with motor thrust, which alleviates the difficulty of opening the door to some extent, but still has the following significant defects:

[0004] 1. Running efficiency and safety hazard, the push rod motor is limited by its own mechanical characteristics, and the process is slow to prevent the door body from impacting, but the low-speed door opening process will cause the high-temperature steam and oil stain gas in the cavity to be concentrated and discharged above the door body. This not only causes oil stain accumulation and cleaning difficulty, but also may cause user scalding risk due to steam accumulation. In addition, if the user forcibly manually closes the door when the motor is not fully reset, it is easy to cause damage to the door structure or safety accidents.

[0005] 2. Cost and durability defects, the push rod motor itself is high in cost, and long-term frequent use is easy to be damaged due to mechanical wear or circuit failure, increasing the maintenance cost and limiting its popularity in high-end cooking devices.

[0006] Therefore, there is an urgent need for a door opening scheme that takes into account efficiency and low cost to meet the dual needs of user experience and functional reliability of cooking devices. INVENTION CONTENTS

[0034] Referring to Figure 1 and Figure 2 , Figure 1 and Figure 2 respectively show structural schematic diagrams of a cooking device 100 in different states in an embodiment of the present application. The cooking device 100 provided in the embodiment of the present application includes an inner container 110 and a door body 120. The inner container 110 is provided with an open cooking cavity 111. The door body 120 covers the inner container 110, and when the door body 120 covers the inner container 110, the door body 120 covers the opening of the cooking cavity 111 to form a closed cooking cavity 111 for cooking food.

[0035] In combination with Figure 3 shown, Figure 3 shows an exploded structural schematic diagram of the door body 120 of the cooking device 100 and the following handle assembly 130 in an embodiment of the present application. The cooking device 100 further includes a handle assembly 130, as shown in Figure 3 The handle assembly 130 includes a connecting rod 131 and a push rod 132, in combination with Figures 4 to 6 The connecting rod 131 is rotatably connected to the end face of the door body 120 away from the inner container 110 along a rotating axis, in combination with Figure 3 The rotating axis is horizontally arranged, as shown in Figures 4 to 6 The push rod 132 is rotatably connected to one end of the connecting rod 131, and as shown in Figure 4 The end of the push rod 132 away from the connecting rod 131 extends towards the inner container 110, as shown in Figure 4 and Figure 5As shown, when the handle assembly 130 is configured to rotate the connecting rod 131 away from the push rod 132 to the direction away from the door body 120, the connecting rod 131 has a tendency to drive the push rod 132 to slide towards the inner container 110, at this time, the push rod 132 has a tendency to abut against the inner container 110, or the push rod 132 has abutted against the inner container 110 before the connecting rod 131 rotates, at this time, the connecting rod 131 continues to rotate, the connecting rod 131 has a tendency to drive the push rod 132 to continue to move, then the push rod 132 has a force to press the inner container 110, and the push rod 132 is subjected to a reverse force of the inner container 110 to the push rod 132, which will drive the handle assembly 130 and the door body 120 connected with the handle assembly 130 to rotate relative to the inner container 110, thereby achieving the effect of door opening assistance.

[0036] As shown in the drawings, Figures 3 to 6 In one embodiment, the connecting rod 131 includes a first segment 1311 and a second segment 1312 arranged at an included angle, and the connection between the first segment 1311 and the second segment 1312 is the position where the connecting rod 131 is rotationally connected to the door body 120, so as to avoid the door body 120 interfering with the rotation of the connecting rod 131. In other embodiments, the first segment 1311 and the second segment 1312 can also be arranged at a straight angle, i.e., both are in the same plane, at this time, the door opening assistance can also be achieved by rotating the second segment 1312.

[0037] As shown in the drawings, Figures 3 to 6 In one embodiment, the first segment 1311 and the second segment 1312 are arranged at an obtuse angle, on the one hand, to avoid the door body 120 interfering with the rotation angle of the first segment 1311, and on the other hand, there is a gap between the second segment 1312 and the door body 120 to facilitate placing the hand below the second segment 1312 to rotate the second segment 1312. In use, the user can hold the second segment 1312 or the following handle 133 with the palm facing upwards, and the palm center is opposite to the inner side of the second segment 1312 or the following handle 133 to facilitate the opening force. The handle 133 is lifted by force, and the door body 120 is forced upward in the opposite direction of the door body 120, at this time, the push rod 132 pushes the door forward, overcomes the closing force of the door body 120, and opens a gap in the door body 120, thereby achieving the effect of assistance. In other embodiments, the first segment 1311 and the second segment 1312 can also be arranged at an acute angle.

[0038] According to the characteristics of the hinge that provides the closing force of the door body 120, the highest point of the force is about 1° when the angle between the door body 120 and the face cover plate of the cooking device 100, and then the force decreases rapidly. Exemplarily, in the present embodiment, as shown in the drawings, Figure 5 The stroke angle of the connecting rod 131 during the door opening assistance is about 1.5°, but not as a limitation.

[0039] As shown in the drawings, Figures 3 to 6As shown, in one embodiment, the push rod 132 is connected to the end of the first segment 1311 away from the second segment 1312, and the length L1 of the first segment 1311 is less than the length L2 of the second segment 1312. At this time, the torque M = F2 × L2 is generated at the position where the connecting rod 131 is rotated and connected to the door body 120, corresponding to the force F2 acting on the second segment 1312. At the same time, the torque M is also generated at the position where the connecting rod 131 is rotated and connected to the door body 120, corresponding to the force F1 acting on the first segment 1311. Then M = F1 × L1. When L1 < L2, the force F1 acting on the second segment 1312 is F2, and the force F1 acting on the first segment 1311 is F2. The force on the first section 1311 is the reaction force between the push rod 132 and the inner liner 110, which applies a small pulling force to the second section 1312, while the inner liner 110, which has a greater pulling force, applies a reaction force to the push rod 132, thus making it easier to open the door.

[0040] like Figures 3 to 6 As shown, in one embodiment, the door 120 includes an outer door 121 and a guide plate 122 connected to the outer door 121, as... Figures 4 to 6 As shown, the outer door 121 is located on the side of the door body 120 opposite to the inner liner 110, and the connecting rod 131 is connected to the outer door 121, as... Figure 4 As shown, the guide plate 122 extends from the outer door 121 toward the inner liner 110. The push rod 132 is slidably connected to the guide plate 122 in the extension direction of the guide plate 122, so that the guide plate 122 guides the movement of the push rod 132, thereby making the force between the push rod 132 and the inner liner 110 in the direction of opening the door 120, so as to achieve greater door opening assistance.

[0041] like Figure 4 As shown, in one embodiment, a limiting rail 1321 is provided on the end face of one of the guide plate 122 and the push rod 132 facing the other of the guide plate 122 and the push rod 132. The limiting rail 1321 is arranged along the extension direction of the guide plate 122, and a sliding limiting member 1221 is protruding on the end face of the other of the guide plate 122 and the push rod 132, which is located on the limiting rail 1321. The sliding limiting member 1221 is partially located in the limiting rail 1321 and slides with the limiting rail 1321, so that the sliding limiting member 1221 is guided by the limiting rail 1321, thereby guiding the movement of the push rod 132 by the guide plate 122. The limiting rail 1321 also limits the movable distance of the sliding limiting member 1221. In this embodiment, the end face of the push rod 132 facing the guide plate 122 is provided with a limiting rail 1321. The limiting rail 1321 is arranged along the extending direction of the guide plate 122, and the end face of the guide plate 122 is provided with a sliding limiting member 1221 that is located on the limiting rail 1321. The reverse is also possible.

[0042] Combination Figure 7 As shown in one of the embodiments, the end face of the limiting rail 1321 is also provided with a mounting groove 1322 in communication with the limiting rail 1321, such as 3 and Figure 7 As shown, the sliding limiting member 1221 is used to slide and fit the part of the limiting rail 1321 which can pass through the mounting groove 1322 to enter the limiting rail 1321. As Figure 3 As shown, in the present embodiment, the sliding limiting member 1221 is in a T-shaped structure, and correspondingly, the limiting rail 1321 is also in a T-shaped structure, and the sliding limiting member 1221 can pass through the mounting groove 1322 to enter the limiting rail 1321, so as to facilitate the installation of the sliding limiting member 1221.

[0043] As shown, in one of the embodiments, the handle assembly 130 includes a plurality of connecting rods 131, and each connecting rod 131 is connected with a push rod 132, and adjacent connecting rods 131 are arranged in the direction of the rotation axis to make the door body 120 bear force evenly. In the present embodiment, the number of the connecting rods 131 and the corresponding push rods 132 is 2, and the two connecting rods 131 are symmetrically arranged with respect to the vertical central axis of the door body 120. In other embodiments, the number of the connecting rods 131 and the corresponding push rods 132 can also be single or other numbers. Figures 1 to 3 As shown, in one of the embodiments, the handle assembly 130 includes a handle 133 connected to one end of the connecting rod 131 away from the push rod 132, so as to facilitate force application. When the number of the connecting rods 131 is multiple, the handle 133 is connected to each connecting rod 131, so that when the user pulls the handle 133, the pulling force can be distributed to each connecting rod 131, thereby realizing uniform force bearing of the door body 120.

[0044] Figures 1 to 3 As shown, in one of the embodiments, the handle assembly 130 further includes a fixing block 134 connected to the end face of the door body 120 away from the inner container 110, and the connecting rod 131 is rotationally connected to the fixing block 134, which on the one hand prolongs the distance between the connecting rod 131 and the outer door 121 of the door body 120, avoids the interference of the door body 120 with the rotation of the connecting rod 131, and on the other hand, can also improve the connection strength of the handle assembly 130 and the door body 120, and avoid the handle assembly 130 from falling off due to the excessive reaction force of the inner container 110 on the push rod 132.

[0045] As shown, in one of the embodiments, the handle assembly 130 further includes a fixing block 134 connected to the end face of the door body 120 away from the inner container 110, and the connecting rod 131 is rotationally connected to the fixing block 134, which on the one hand prolongs the distance between the connecting rod 131 and the outer door 121 of the door body 120, avoids the interference of the door body 120 with the rotation of the connecting rod 131, and on the other hand, can also improve the connection strength of the handle assembly 130 and the door body 120, and avoid the handle assembly 130 from falling off due to the excessive reaction force of the inner container 110 on the push rod 132.
