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 increasing. 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

[0033] Reference Figure 1 , Figure 1 A structural schematic diagram of a cooking device 100 in an embodiment of the present application is shown. The cooking device 100 provided by the embodiment of the present application can be a steam oven, an oven, a steaming oven, or any other device with cooking function.

[0034] As Figure 1 shown, the cooking device 100 includes a main body 110, a door body 120 and a handle assembly 130, wherein the main body 110 is provided with an open cooking cavity 111 for placing and cooking food materials. The door body 120 is provided on the main body 110, and when the door body 120 is provided on the main body 110, the door body 120 covers the opening of the cooking cavity 111.

[0035] In combination Figure 2 shown, Figure 2 A structural schematic diagram of the door body 120 and the handle assembly 130 of the cooking device 100 in an embodiment of the present application is shown. As Figure 1 and Figure 2 shown, the handle assembly 130 includes a fixed block 131, a push rod 132 and a pull rod 133, wherein the fixed block 131 is connected to the end face of the door body 120 away from the main body 110, and the pull rod 133 is rotatably connected to the fixed block 131 between an initial position shown by a dashed line in Figure 2 and an open position shown by a solid line in Figure 2 , such as Figure 2 and Figure 3As shown, the pull rod 133 is rotatably connected to the fixed block 131 on the side away from the door body 120, and the fixed block 131 does not interfere with the rotation of the pull rod 133 between the initial position and the open position.

[0036] like Figure 2 and Figure 3 As shown, push rod 132 is connected to pull rod 133 and protrudes from the end face of pull rod 133 facing the main body 110, as... Figure 2 and Figure 3 In the illustrated embodiment, one end of the push rod 132 is connected to the pull rod 133, and the other end extends toward the direction of the main body 110. And as... Figure 2 and Figure 3 As shown, the push rod 132 and the fixing block 131 are spaced apart, as... Figure 2 As shown, when the lever 133 rotates from the initial position toward the open position, the lever 133 will drive the push rod 132 to move toward the direction closer to the main body 110.

[0037] When the pull rod 133 is in the initial position or in any position between the initial position and the open position, the end of the push rod 132 away from the pull rod 133 abuts against the end face of the main body 110 facing the door 120. At this time, the pull rod 133 continues to rotate toward the open position, which will push the push rod 132 to exert force on the main body 110. At this time, the reaction force of the main body 110 on the push rod 132 will push the pull rod 133 away, so that the pull rod 133, the fixing block 131 and the door 120 move together to facilitate the opening of the door 120. Thus, the reaction force of the main body 110 on the push rod 132 provides an assisting effect for opening the door 120.

[0038] In some embodiments, when the pull rod 133 is in the initial position, the end of the push rod 132 away from the pull rod 133 abuts against the end face of the main body 110 facing the door 120. When the pull rod 133 rotates toward the open position, the reaction force of the main body 110 on the push rod 132 will drive the door 120 to open. However, it should be noted that when the pull rod 133 is in the initial position, the interaction force between the main body 110 and the push rod 132 does not interfere with the closing of the door 120.

[0039] In some embodiments, when the pull rod 133 is in a position between the initial position and the open position, the end of the push rod 132 away from the pull rod 133 abuts against the end face of the main body 110 facing the door 120. As the pull rod 133 rotates from the initial position toward the open position, the push rod 132 gradually approaches the end face of the main body 110 facing the door 120 and then abuts against the main body 110. As the pull rod 133 rotates, the force between the main body 110 and the push rod 132 increases until the interaction force between the main body 110 and the push rod 132 and the pulling force on the pull rod 133 together overcome the opening resistance of the door 120, and the door 120 opens.

[0040] As shown in Figure 2 and Figure 2 shown, in one of the embodiments, the length of the pull rod 133 between the push rod 132 and the fixed block 131 is less than 1 / 2 of the total length of the pull rod 133, so that the pulling force of the pull rod 133 can provide more force to the push rod 132 on the main body 110, thereby obtaining more reaction force of the main body 110 on the push rod 132, thereby increasing the assist force of the reaction force of the main body 110 on the push rod 132 on the door body 120.

[0041] As shown in Figures 2 to 4 shown, in one of the embodiments, the pull rod 133 includes a pulling portion 1331 and a pushing portion 1332, the connection position of the fixed block 131 and the pull rod 133 is the connection position of the pulling portion 1331 and the pushing portion 1332, the push rod 132 is connected to one end of the pushing portion 1332 away from the pulling portion 1331, and the length L of the pulling portion 1331 is greater than the length l of the pushing portion 1332. Exemplarily, in the embodiment shown in Figure 2 and Figure 3 , the relationship between the length L of the pulling portion 1331 and the length l of the pushing portion 1332 is L≈10l, at this time, the pulling force acting on the pulling portion 1331, if the force position is the end of the pulling portion 1331 farthest away from the push rod 132, then the interaction force between the push rod 132 and the main body 110 at this time is about 10 times the pulling force, assuming that the force required for the door body 120 to open is 100N (Newton), the pulling force acting on the end of the pulling portion 1331 farthest away from the push rod 132 only needs 10N, thereby realizing that a smaller pulling force obtains a larger reaction force of the main body 110 on the push rod 132, thereby increasing the assist force effect of the reaction force of the main body 110 on the push rod 132 on the door body 120. It can be understood that the above is only an example of the pulling force acting on the end of the pulling portion 1331 farthest away from the push rod 132, and is not an actual application. In fact, the pulling force can act on any position of the pulling portion 1331. In other embodiments, the length L of the pulling portion 1331 is greater than the length l of the pushing portion 1332, which is not further limited.

[0042] As shown in Figure 1 shown, in one of the embodiments, the end surface of the door body 120 connected to the fixed block 131 is provided with a relief hole 121, and the relief hole 121 is located at the push rod 132, as shown in Figure 2 and Figure 3 , the push rod 132 passes through the relief hole 121, so that the push rod 132 can directly abut against the main body 110 when moving with the pull rod 133, so that the length of the pull rod 133 does not need to be longer than the length of the door body 120, avoiding that the handle assembly 130 affects the appearance of the cooking equipment 100.

[0043] As shown in Figure 4As shown, in one embodiment, the push rod 132 is rotatably connected to the pull rod 133. In other embodiments, the push rod 132 can also be fixedly connected to the pull rod 133. In this case, the push rod 132 and the pull rod 133 are set at an angle, and the clearance hole 121 needs to leave more room for movement. The tension on the pull rod 133 can still make the push rod 132 abut against the main body 110.

[0044] In one embodiment, the axis of rotation of push rod 132 (e.g. Figure 4 The axis of rotation between the fixed block 131 and the tie rod 133 (as shown by the dashed line in the middle) and the fixed block 131 and tie rod 133 (as shown by the dashed line in the middle) Figure 4 As shown by the dashed line, in this embodiment, the rotation axis of the push rod 132, the rotation axis between the fixed block 131 and the pull rod 133 are all vertical.

[0045] like Figure 2 As shown, in one embodiment, the rotation angle α of the lever 133 from the initial position to the open position is 10° to 20°, that is, α is 15°±5°. Figure 2 The diagram shows an example with α = 15°. At this angle, the pulling force of the lever 133 can be converted into the pushing force of the push rod 132 to a greater extent. However, when the rotation angle is too large, the component of the pulling force perpendicular to the lever 133 along the direction of the push rod 132 will be less. When the rotation angle is too small, it is not convenient to operate.

[0046] like Figure 2 and Figure 3 As shown, in one embodiment, the handle assembly 130 further includes a limiting member 135, which is connected to the end face of the fixing block 131 facing the pull rod 133. When the pull rod 133 is in the initial position, the pull rod 133 abuts against the limiting member 135 and is parallel to the end face of the connecting fixing block 131 of the door body 120. This is to ensure that the pull rod 133 is parallel to the outer end face of the door body 120 in the initial position, thus ensuring the integrity of the appearance of the cooking equipment 100.

[0047] like Figures 1 to 4 As shown, in one embodiment, the handle assembly 130 further includes a locking block 134. The locking block 134 is connected to the end face of the connecting fixing block 131 of the door body 120. The locking block 134 is spaced apart from the fixing block 131 and is located on the side of the fixing block 131 away from the push rod 132. The locking block 134 engages with the pull rod 133 in the initial position to limit the pull rod 133 in the initial position and prevent the pull rod 133 from shaking and affecting the closing of the door body 120.

[0048] like Figure 4 As shown, in one embodiment, the positions of the fixing block 131 and the locking block 134 are symmetrically arranged along the vertical center line of the pull rod 133 so that the force on the pull rod 133 in the initial position is more uniform.

[0049] As shown in Figure 5 and Figure 6 In one embodiment, the pull rod 133 is provided with a first clamping block 1333, the locking block 134 is provided with a locking groove 1341 located at the first clamping block 1333, the locking block 134 further comprises a second clamping block 1342 located in the locking groove 1341, the first clamping block 1333 is concavely provided with a clamping groove 13331, the opening direction of the clamping groove 13331 is perpendicular to the relative moving direction of the first clamping block 1333 and the second clamping block 1342, in this embodiment, the clamping groove 13331 is open at the top end, when the first clamping block 1333 and the second clamping block 1342 move relative to each other, the second clamping block 1342 can be at least partially inserted into the clamping groove 13331, so that the locking block 134 and the pull rod 133 are clamped and connected. Figure 5 and Figure 6 As shown in

[0050] As shown in Figure 4 In this embodiment, in the direction perpendicular to the end surface of the connecting and fixing block 131 of the door body 120, the projection of the push rod 132, the projection of the fixing block 131, the projection of the limiting piece 135 and the projection of the locking block 134 are all located in the projection of the pull rod 133, so that Figure 4 As shown in

[0051] The cooking device 100 provided in the above scheme, by setting the pull rod 133 which can rotate between the initial position and the open position, and connecting the push rod 132 with the pull rod 133, when the pull rod 133 is in the initial position or between the initial position and the open position, the push rod 132 abuts against the main body 110, so that when the pull rod 133 continues to rotate towards the open position, the push rod 132 is pushed to apply force to the main body 110, with the rotation of the pull rod 133, the interaction force between the main body 110 and the push rod 132 becomes larger and larger, until the interaction force between the main body 110 and the push rod 132 and the pulling force on the pull rod 133 together overcome the door opening resistance of the door body 120, at this time, the reaction force of the main body 110 on the push rod 132 will push away the pull rod 133, so that the pull rod 133, the fixing block 131 and the door body 120 move together to open the door body 120, thereby the reaction force of the main body 110 on the push rod 132 plays a power assisting effect on the opening of the door body 120.

[0052] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, as long as there is no conflict, any combination of the technical features should be considered within the scope of the present disclosure.

[0053] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
