Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and in particular to a panel lifting mechanism for cooking equipment and cooking equipment. Background Technology

[0002] In modern kitchens, integrated and intelligent kitchen appliances are increasingly favored by consumers. For example, the microwave-steam-oven combo combines the functions of a microwave oven, steamer, and oven, and can perform multiple cooking tasks such as steaming, baking, frying, and microwaving in one cooking cavity, allowing users to complete diverse cooking in one device.

[0003] In related technologies, cooking equipment includes a main body, a control panel, a water tank, and a lifting mechanism. The main body has a cooking cavity and a receiving cavity located above the cooking cavity. The receiving cavity has an opening on the front side facing the main body. The water tank is placed in the receiving cavity through the opening. The control panel covers the opening of the receiving cavity to seal the water tank inside the receiving cavity. The lifting mechanism includes a drive motor and a connecting arm. The connecting arm is located above the drive motor and connected to the drive motor. The control panel is connected to a transmission component. In this way, the drive motor can drive the transmission component to move, thereby causing the transmission component to lift the control panel upward and reset it downward, thereby opening or closing the opening of the receiving cavity, which facilitates the replacement, repair, or maintenance of the water tank.

[0004] However, in related technologies, the pressure of the control panel and connecting arm is directly applied to the drive shaft of the drive motor, which causes the drive shaft to deform under stress, resulting in low reliability and poor stability of the control panel opening or closing the cavity opening. Utility Model Content

[0005] In view of the above problems, this application provides a panel lifting mechanism and a cooking device for cooking equipment, which aims to reduce the stress deformation of the drive shaft of the drive motor and improve the reliability and stability of the control panel opening or closing the opening of the receiving cavity.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] The first aspect of this application provides a panel lifting mechanism for a cooking device, comprising:

[0008] A bracket extending in a first direction, the bracket having a first guide groove extending in the first direction, the first guide groove being at least partially curved in its own extending direction to form a height difference in a second direction;

[0009] A connecting arm, the first end of which is exposed outside the bracket and connected to the panel, a portion of the connecting arm is slidably constrained within the first guide groove, and the connecting arm is configured to drive the panel to reciprocate in the first direction under a sliding force, so that the panel is raised or lowered in the second direction, wherein the second direction has an angle with the first direction;

[0010] A drive unit is disposed near the connecting arm. The power output end of the drive unit has a transmission component. The transmission component is located above the connecting arm and can rotate relative to the connecting arm in either the forward or reverse direction. This allows the transmission component to act on the connecting arm while rotating, thereby driving the connecting arm to reciprocate relative to the bracket.

[0011] In the panel lifting mechanism provided in this application embodiment, by setting the transmission component above the connecting arm, the transmission component is driven by the drive unit to rotate in the forward or reverse direction, so that the connecting arm reciprocates relative to the bracket in the first direction and is lifted or lowered in the second direction. During this process, the transmission component is not subjected to the direct force of the control panel, that is, the panel is directly set on the transmission component and subjected to the direct force of the panel, thereby reducing the deformation of the transmission component and improving the reliability and stability of the connecting arm and the panel when moving relative to the cooking equipment cavity.

[0012] In some embodiments, the drive unit further includes a drive motor connected to the bracket, and the drive shaft of the drive motor is coaxially arranged with the transmission member to drive the transmission member to rotate in the forward or reverse direction.

[0013] With this configuration, by driving the shaft to rotate in the forward or reverse direction via the drive motor, the connecting arm and panel can reciprocate along the first guide groove relative to the support, and the panel can be lifted or lowered along the second direction, thereby improving the reliability and stability of the panel opening or closing the cavity opening.

[0014] In some embodiments, the bracket has a sliding gap extending along the first direction, the second end of the connecting arm is located within the sliding gap and reciprocates within the sliding gap along the first direction, and the first end of the connecting arm is always located outside the sliding gap and connected to the panel.

[0015] This design protects the connecting arm by placing it within the sliding gap, reducing damage to the connecting arm and improving the reliability and stability of the panel during transmission.

[0016] In some embodiments, the transmission element is a gear, the upper side of the connecting arm has teeth, and the extension trajectory of the teeth matches the extension trajectory of the first guide groove, and the teeth mesh with the gear.

[0017] This design enables the transmission between the transmission component and the connecting arm to be a gear meshing transmission, which is simple in structure, easy to implement, and low in cost.

[0018] In some embodiments, the connecting arm has a laterally extending first guide post that matches the first guide groove and is located within the first guide groove, and is capable of reciprocating within the first guide groove.

[0019] With this configuration, by setting a first guide post on the connecting arm, the connecting arm can be controlled to reciprocate along the extension direction of the first guide groove, thereby improving the reliability and stability of the control panel in opening or closing the opening of the receiving cavity.

[0020] In some embodiments, a first bushing is fitted onto the first guide post, and the first bushing is in direct contact with at least a portion of the groove wall of the first guide groove.

[0021] With this configuration, by fitting a first bushing onto the first guide post, the movement between the first guide post and the first guide groove becomes a rolling motion, reducing the friction between the first guide post and the first guide groove, making the relative movement between the connecting arm and the bracket smoother, thereby improving the reliability and stability of the movement of the connecting arm relative to the bracket.

[0022] In some embodiments, the connecting arm has a second guide groove along a first direction, and the teeth are located on the outer side of the upper groove wall of the second guide groove; the bracket has a second guide post extending laterally, and the gear and the second guide post are arranged opposite to each other in the vertical direction with a gap, the second guide post is supported and abuts against the inner side of the groove wall of the second guide groove, and both the teeth and the second guide post can act on the upper groove wall of the second guide groove so that the upper groove wall of the second guide groove has a tendency to return to its original position when deformed.

[0023] This configuration, through the setting of the second guide post and the second guide groove, combined with the setting of the first guide post and the first guide groove, allows the relative movement between the connecting arm and the bracket to be controlled by the two guide grooves, improving the guiding performance of the connecting arm and thus enhancing the reliability and stability of the movement of the connecting arm relative to the bracket. In addition, the teeth and the second guide post can apply two opposing forces to the upper wall of the second guide groove, so as to reset the deformation of the upper wall of the second guide groove, thereby improving the structural guiding performance of the second guide groove.

[0024] In some embodiments, the wall of the second guide groove is at least partially curved in its own extending direction;

[0025] The gear and the second guide post overlap vertically on the same surface.

[0026] With this configuration, when the connecting arm moves in the first direction, it creates a height difference in the second direction, thereby causing the panel to rise or fall in the second direction, so that the panel can open or close the receiving cavity opening, facilitating the removal and placement of the water tank. In addition, the projection portions of the gear and the second guide post on the same surface in the vertical direction overlap, so that the two forces exerted by the gear and the second guide post on the upper wall of the second guide groove in the second direction can be partially opposite to each other, so as to correct and reset the deformation of the upper wall of the second guide groove in the second square, thereby improving the structural guidance of the second guide groove.

[0027] In some embodiments, a second bushing is fitted onto the second guide post, and the second bushing is in direct contact with at least a portion of the groove wall of the second guide groove.

[0028] This configuration, by fitting a second bushing onto the second guide post, makes the movement between the second guide post and the second guide groove a rolling motion, reducing the friction between the second guide post and the second guide groove, and making the relative movement between the connecting arm and the bracket smoother, thereby improving the reliability and stability of the movement of the connecting arm relative to the bracket.

[0029] In some embodiments, the bracket includes two sub-brackets, which are opposite to each other along a third direction and detachably connected, and the two sub-brackets together form the sliding gap; wherein the third direction has an angle with the first direction and the second direction respectively;

[0030] Both sub-supports have the first guide grooves arranged opposite to each other, and the two sides of the connecting arm are slidably constrained within the corresponding first guide grooves.

[0031] This configuration, by placing the connecting arm between the two sub-supports, distributes the force exerted by the connecting arm on the support onto the two sub-supports. This also distributes the reaction force from the two sub-supports on both sides of the connecting arm, resulting in a more even force distribution and thus making the movement of the connecting arm and control panel relative to the support more stable.

[0032] In some embodiments, both sub-supports have limiting holes, the second guide post passes through the second guide groove, and both ends pass through the limiting holes respectively;

[0033] The second guide post has limiting structures at both ends, which are located outside the sliding gap and abut against the surface of the corresponding sub-support.

[0034] With this configuration, by setting limiting structures at both ends of the second guide post, the position of the second guide post can be limited in the corresponding limiting holes, thereby controlling the distance between the two sub-supports, preventing the two sub-supports from contacting each other, and preventing swaying between the two sub-supports, thus improving the stability of the movement of the connecting arm and control panel relative to the two sub-supports.

[0035] In some embodiments, there are two brackets and two connecting arms, the two brackets are spaced apart along a third direction, one bracket corresponds to one connecting arm, and the first end of both connecting arms is connected to the panel;

[0036] The drive unit includes a connector and two transmission components. The connector is connected between the two transmission components. Each transmission component corresponds to one connecting arm. The two transmission components are located above their respective connecting arms.

[0037] The drive motor is connected to one of the two transmission components, so that one of the two transmission components drives the other of the two transmission components to move through the connecting member.

[0038] This configuration serves two purposes. First, the two connecting arms and two supports increase the number of points of contact between the panel and the cooking equipment, thereby improving the stability of the panel's movement relative to the cooking equipment's cavity. Second, the connection components and the drive motor ensure that the movement of the two connecting arms relative to the two supports is synchronized, thus improving the reliability of the panel's movement relative to the cooking equipment's cavity.

[0039] In some embodiments, the panel lifting mechanism further includes a first micro switch and a second micro switch, the first micro switch and the second micro switch being respectively disposed at both ends of the first guide groove, and the first micro switch and the second micro switch being configured to be signal-connected to a control unit in the cooking device; and / or,

[0040] The connecting arm has a wire channel configured to accommodate wires electrically connected to the panel.

[0041] With this configuration, when the first guide post moves to both ends of the first guide groove via the first and second micro switches, the control unit sends a stop signal to the drive motor to avoid over-driving of the drive motor. In addition, the wire groove is designed to prevent the wire from coming off the connecting arm, thereby improving the reliability of the panel control.

[0042] A second aspect of this application provides a cooking device, including a device body, a panel, and a panel lifting mechanism as described in any one of the above claims;

[0043] The device body has an inner liner and a receiving cavity located above the inner liner. The front side of the device body has an opening communicating with the receiving cavity. The panel is movably disposed at the opening and connected to the panel lifting mechanism. The panel lifting mechanism is configured to drive the panel to move so that the panel opens or closes the opening.

[0044] The front-back direction of the device body is formed as the first direction, the up-down direction of the device body is formed as the second direction, and the left-right direction of the device body is formed as the third direction.

[0045] The cooking device provided in this application embodiment has the same beneficial effects as the panel lifting mechanism provided in the first aspect above, and will not be described again here.

[0046] In addition to the technical problems solved by the embodiments of this application, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions described above, other technical problems that the panel lifting mechanism for cooking equipment and the cooking equipment provided by the embodiments of this application can solve, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further explained in detail in the specific implementation.

[0068] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0069] This application provides a cooking device, including but not limited to microwave ovens, steam ovens, ovens, and microwave-steam-oven combos. The cooking device includes a main body, a water tank, a control panel 200, and a control panel lifting mechanism 100. The main body has an inner liner and a receiving cavity above the inner liner. The front side of the main body has an opening communicating with the receiving cavity. The water tank can be placed into or removed from the receiving cavity through the opening. The control panel 200 is movably disposed at the opening and connected to the control panel lifting mechanism 100. The control panel lifting mechanism 100 is configured to drive the control panel 200 to move, thereby opening or closing the opening, thus improving the overall structural compactness and aesthetics of the cooking device. For example, the control panel 200 is a user-operable control panel for changing cooking tasks, etc.

[0070] Understandably, the water tank can provide steam for cooking equipment during steaming, baking, and other cooking tasks to ensure the taste of the food.

[0071] The structure of the panel lifting mechanism for cooking equipment provided in the embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0072] Please note this in advance, such as Figure 1 or Figure 2 As shown, the first direction is the front-to-back direction of the cooking device body. When the operator is facing the cooking device, the side of the cooking device closer to the operator is the front side of the cooking device, and the side farther away from the operator is the rear side of the cooking device. The second direction is the up-down direction of the device body, i.e., the vertical direction. The third direction is the left-to-right direction of the device, i.e., the direction in which the panel 200 extends horizontally. The second direction and the first direction have an angle between them, and the third direction has an angle between the first direction and the second direction, respectively. For example, these angles are all 90°.

[0073] Continue to refer to Figure 1 and Figure 2As shown, the panel lifting mechanism 100 includes a bracket 110 and a connecting arm 120. The bracket 110 extends along a first direction and has a first guide groove 111 extending along the first direction. The first guide groove 111 is at least partially curved in its own extending direction to form a height difference in a second direction. The first end 121 of the connecting arm 120 is exposed outside the bracket 110 and connected to the panel 200. A portion of the structure of the connecting arm 120 is slidably constrained within the first guide groove 111. The connecting arm 120 is configured to drive the panel 200 to reciprocate in the first direction under a sliding force, so that the panel 200 is raised or lowered in the second direction, thereby opening or closing the opening of the receiving cavity, which facilitates the replacement, repair or maintenance of the water tank.

[0074] In addition, the panel lifting mechanism 100 also includes a drive unit 130. The drive unit 130 is located close to the connecting arm 120. The power output end of the drive unit 130 has a transmission component 131. The transmission component 131 is located above the connecting arm 120 and can rotate relative to the connecting arm 120 in the forward or reverse direction. This allows the transmission component 131 to act on the connecting arm 120 while rotating, thereby driving the connecting arm 120 to reciprocate relative to the bracket 110 and causing the panel 200 to open or close the opening of the receiving cavity.

[0075] Furthermore, the drive unit 130 also includes a drive motor 132. The drive shaft of the drive motor 132 can rotate forward and backward. The drive motor 132 is fixedly mounted on one side of the connecting arm 120 relative to the bracket 110. The drive shaft of the drive motor 132 is coaxially mounted with the transmission component 131 to drive the transmission component 131 to rotate in the forward or reverse direction, thereby enabling the connecting arm 120 to reciprocate relative to the bracket 110 along the first guide groove 111. For example, the drive motor 132 and the bracket 110, and the drive shaft of the drive motor 132 and the transmission component 131 are all fixedly connected. The fixed connection methods include, but are not limited to, welding, bolt and nut connection, snap-fit, adhesive bonding, and pin connection.

[0076] In this embodiment, since the transmission component 131 is located above the connecting arm 120 and the drive motor 132 is located on one side of the connecting arm 120, the weight of the connecting arm 120 and the panel 200 will not act on the transmission component 131 and the drive motor 132, thereby preventing deformation of the drive shaft of the transmission component 131 and the drive motor 132, thus improving the overall reliability of the drive unit 130. In addition, the drive shaft of the drive motor 132 drives the transmission component 131 to rotate forward or backward by rotating in the forward or reverse direction, thereby causing the connecting arm 120 to reciprocate along the extension trajectory of the first guide groove 111, thereby causing the first end 121 of the connecting arm 120 to reciprocate in the first direction, thereby causing the panel 200 to reciprocate in the direction of approaching and moving away from the bracket 110. At the same time, the connecting arm 120 causes the panel 200 to rise and fall in the second direction (e.g., vertical), thereby allowing the panel 200 to open or close the opening of the receiving cavity for the replacement, repair or maintenance of the water tank.

[0077] For example, the transmission member 131 and the connecting arm 120 can be in frictional contact, so that when the transmission member 131 rotates in the forward or reverse direction, the connecting arm 120 can be driven to reciprocate along the first guide groove 111 by the frictional force between them.

[0078] In another example, the transmission component 131 is a gear, and the connecting arm 120 has a rack that matches the gear. In this way, the gear meshes with the rack, and when the gear rotates in the forward or reverse direction, the connecting arm 120 can be driven to reciprocate along the first guide groove 111 by the rack.

[0079] In addition, the axis of the transmission component 131 can be set horizontally along the third direction. In this way, when the transmission component 131 rotates in the forward or reverse direction, it can drive the connecting arm 120 to move the panel 200 back and forth along the first guide groove 111 through friction or gear meshing, so that the panel 200 moves in the first direction and the second direction, thereby opening or closing the opening of the accommodating cavity.

[0080] Alternatively, the axis of the transmission component 131 can extend along a second direction (e.g., vertically), and the side wall of the connecting arm 120 near the top can make frictional contact or mesh with the transmission component 131. In this way, when the transmission component 131 rotates in the forward or reverse direction, the connecting arm 120 can be driven by friction or gear meshing to move the panel 200 back and forth along the first guide groove 111. In this way, the connecting arm 120 does not need to bear the weight of the transmission component 131, thereby avoiding the problem of deformation of the connecting arm 120 due to force.

[0081] It should be noted that, in the above embodiments, the connection between the first end 121 of the connecting arm 120 and the panel 200 is, by way of example, a fixed connection. The fixed connection method includes, but is not limited to, welding, bolt and nut connection, snap-fit, adhesive bonding, pin connection, etc.

[0082] In addition, such as Figure 3 As shown, the bracket 110 has a sliding gap 112 extending along a first direction inside. The second end 122 of the connecting arm 120 is located inside the sliding gap 112 and reciprocates within the sliding gap 112 along the first direction. The first end 121 of the connecting arm 120 is always located outside the sliding gap 112 and is connected to the panel 200. In this way, the connecting arm 120 reciprocates within the sliding gap 112 along the first direction, which can prevent the connecting arm 120 from being exposed to the environment, improve the overall aesthetics and structural compactness of the cooking equipment, and also protect the connecting arm 120, reduce damage to the connecting arm 120, increase the service life of the active components, and improve the reliability and stability of the control panel during transmission.

[0083] In some implementations, such as Figure 3 As shown, the bracket 110 includes two sub-brackets 115, which are detachably connected and positioned opposite each other along a third direction. The two sub-brackets 115 together form a sliding gap 112. Each of the two sub-brackets 115 has a first guide groove 111 arranged opposite to each other, and the two sides of the connecting arm 120 are slidably constrained within the corresponding first guide groove 111. By detachably connecting the two sub-brackets 115, the connecting arm 120 can be installed between them. Furthermore, by positioning the connecting arm 120 between the two sub-brackets 115, the force exerted by the connecting arm 120 on the bracket 110 is distributed across the two sub-brackets 115, and the reaction force on the connecting arm 120 is symmetrically distributed along a third direction, resulting in more uniform force distribution. This makes the movement of the connecting arm 120 and the panel 200 relative to the bracket 110 more stable and reliable. Additionally, as... Figure 4 As shown, the transmission component 131 is a gear, and the connecting arm 120 has teeth 123. The extension trajectory of the teeth 123 matches the extension trajectory of the first guide groove 111, and the teeth 123 mesh with the gear. That is to say, the transmission method between the transmission component 131 and the connecting arm 120 is gear tooth meshing transmission. This structure is simple, easy to implement, and low in cost. Moreover, the extension trajectory of the teeth 123 matches the extension trajectory of the first guide groove 111, so that the connecting arm 120 can reciprocate along the extension direction of the first guide groove 111 under the transmission of the gear teeth 123, thereby driving the panel 200 to extend further or return to its original state in the first direction, and also having the effect of lifting and lowering in the second direction. This allows the opening of the receiving cavity to be fully exposed to the external environment, so as to facilitate the replacement, repair, or maintenance of the water tank.

[0084] An example, such as Figure 4 As shown, when the tooth 123 is a rack composed of multiple single gear teeth arranged side by side along the first direction, that is, when the meshing direction of the tooth 123 and the gear is the first direction, the rack and the connecting arm can be an integral structure or a separate structure. If the rack and the connecting arm are an integral structure, the corresponding position of the connecting arm can be machined into the shape of a rack by machining on the connecting arm. In this process, the machining methods include, but are not limited to, milling, planing, turning, stamping, extrusion, laser cutting, etc. If the rack and the connecting arm are an integral structure, the two can be connected by a fixed connection. The fixed connection methods include, but are not limited to, bolt and nut connection, snap-fit, bonding, pin connection, etc.

[0085] In some embodiments, the transmission member 131 can be a transmission shaft structure, so that the transmission member 131 and the connecting arm 120 are in direct contact, and the frictional force generated between the two is used as the driving force for the movement of the connecting arm 120 relative to the bracket 110. However, in this embodiment, because the transmission member 131 and the connecting arm 120 are in direct contact and relative sliding occurs, the transmission member 131 and the connecting arm 120 will wear, affecting the transmission effect between them.

[0086] When the transmission component 131 is a gear, the number of gears in the transmission component 131 can be one, two, three, four, etc. The arrangement of multiple gears serves two purposes: firstly, it changes the correspondence between the rotation direction of the drive motor 132 and the opening or closing of the receiving cavity by the connecting arm 120 along the second direction, which can be set according to user requirements or ease of installation; secondly, the arrangement of multiple gears changes the transmission efficiency between the drive motor 132 and the connecting arm 120, i.e., controls the speed of the reciprocating motion of the connecting arm 120 along the first guide groove 111. Therefore, multiple gears can be arranged within a limited space to improve transmission efficiency, thereby shortening the time it takes for the connecting arm 120 and the panel 200 to open or close relative to the receiving cavity of the cooking equipment, thus reducing user waiting time and improving the user experience.

[0087] For example, in combination Figures 3 to 5 As shown, the transmission component 131 contains two gears, including a first gear 1311 and a second gear 1312. The first gear 1311 is coaxial with and fixedly connected to the drive shaft of the drive motor 132. The second gear 1312 meshes with the first gear 1311, and the second gear 1312 meshes with the toothed portion 123. Figure 4From the perspective of [the device], if clockwise rotation is considered as positive rotation and counterclockwise rotation as negative rotation, then when the drive shaft of the drive motor 132 rotates in the positive direction, the first gear 1311 rotates in the positive direction along with the drive shaft, and the second gear 1312 rotates in the negative direction, so that the connecting arm 120 drives the panel 200 to move towards the rear of the cooking device, thereby closing the opening of the receiving cavity; when the drive shaft of the drive motor 132 rotates in the negative direction, the first gear 1311 rotates in the negative direction along with the drive shaft, and the second gear 1312 rotates in the positive direction, so that the connecting arm 120 drives the panel 200 to move towards the front of the cooking device, thereby opening the opening of the receiving cavity.

[0088] In the above embodiments, such as Figure 4 and Figure 5 As shown, the first gear 1311 is coaxial with and fixedly connected to the drive shaft of the drive motor 132, and the second gear 1312 meshes with the first gear 1311 for transmission. To maintain the stability and reliability of the first gear 1311 and the second gear 1312 during transmission, one end of the first gear 1311 can be fixedly connected to the drive shaft of the drive motor 132, and the other end can be rotatably mounted on the sub-support 115 near the drive motor 132. Along the third direction, one side of the second gear 1312 meshes with the first gear 1311 for transmission, and the other side meshes with the tooth portion 123 for transmission. Therefore, the side of the second gear 1312 near the tooth portion 123 can mesh with both sub-supports 115. A rotatable connection is provided to stably support the second gear 1312. The fixed connection between the first gear 1311 and the drive shaft of the drive motor 132 includes, but is not limited to, welding, bolt and nut connection, snap-fit, bonding, and pin connection. The rotatable connection between the first gear 1311 and the sub-support 115, and between the second gear 1312 and the sub-support 115, can be achieved by providing corresponding openings on the sub-support 115, with the gear shafts of the first gear 1311 and the second gear 1312 positioned in the corresponding openings, so that the gear shafts of the first gear 1311 and the second gear 1312 can rotate relative to the corresponding openings. No further limitations are made here.

[0089] In addition, such as Figure 3 and Figure 4As shown, the connecting arm 120 has a laterally extending first guide post 124, that is, the axial direction of the first guide post 124 is consistent with the third direction. The first guide post 124 matches the first guide groove 111, and the first guide post 124 is located in the first guide groove 111 and can reciprocate in the first guide groove 111. In this way, by controlling the reciprocating movement of the first guide post 124 in the first guide groove 111, the accuracy of the movement of the connecting arm 120 relative to the bracket 110 is improved. Thus, during the reciprocating movement of the connecting arm 120 relative to the bracket 110 along the first guide groove 111, the reliability and stability of the panel 200 opening or closing the receiving cavity opening are improved.

[0090] Furthermore, in some embodiments, along a third direction, both sides of the connecting arm 120 have laterally extending first guide posts 124. The end of the first guide post 124 away from the connecting arm 120 has a limiting part, which can be a limiting groove or a limiting protrusion. The limiting part is disposed in the sliding gap 112 and abuts against the surface of the corresponding sub-support 115, thereby controlling the distance between the connecting arm 120 and the two sub-supports 115 respectively, and avoiding the connecting arm 120 from swaying along the third direction during the movement of the connecting arm 120 relative to the support 110, and the friction generated between the connecting arm 120 and the two sub-supports 115, which would affect the relative movement of the connecting arm 120.

[0091] It should be further noted that, along the third direction, the two sub-supports 115 are detachably fixedly connected. For example, the detachable fixed connection between the two sub-supports 115 is achieved by providing multiple threaded connecting posts 1154 between the two sub-supports 115, and providing multiple threaded connecting holes on the two sub-supports 115 that match the multiple threaded connecting posts 1154. For example, as shown... Figure 3 and Figure 4 As shown, four threaded connecting posts 1154 are provided between the two sub-supports 115, and four threaded connecting holes are provided at the four corners of the two sub-supports 115 near the edge, so that the two ends of each threaded connecting post 1154 can be fixedly connected to the corresponding threaded connecting holes on the two sub-supports 115, thereby fixing the two sub-supports 115 together and improving the stability of the entire support structure 110.

[0092] Furthermore, since the support 110 is fixedly connected to the cavity wall of the cooking equipment, when the support 110 includes two sub-supports 115, the fixed connection between the two sub-supports and the cavity wall is as follows: Figure 3As shown, for ease of distinction, the sub-support closer to the drive motor 132 is referred to as the right sub-support, and the sub-support farther from the drive motor 132 is referred to as the left sub-support. The left sub-support has a first flange 1152, and the right sub-support has a second flange 1153. Bolt holes are respectively provided on the first flange 1152 and the second flange 1153. The number of bolt holes can be set according to the extension length of the corresponding flange, including but not limited to providing one, two, three, four, five, etc. bolt holes on the corresponding flange. Bolts are passed through the corresponding bolt holes on the first flange 1152 and the second flange 1153 to fix the left and right sub-supports 115 to the cavity wall of the receiving cavity, respectively. The first flange 1152 and the second flange 1153 are staggered on the corresponding sub-supports along the first and second directions, for example, as shown in... Figure 3 As shown, from this perspective, the first flange 1152 is located at the lower right of the left sub-support, and the second flange 1153 is located at the upper left of the right sub-support. This makes the fixing force points of the support 110 on the cavity wall of the accommodating cavity distributed in a three-dimensional direction, thereby improving the reliability of the fixed connection between the support 110 and the cooking equipment.

[0093] To further improve the accuracy of the movement of the first guide post 124 in the first guide groove 111, in some embodiments, such as Figure 4 As shown, a first bushing 125 is fitted onto the first guide post 124, and the first bushing 125 is in direct contact with at least part of the groove wall of the first guide groove 111. This makes the movement between the first guide post 124 and the first guide groove 111 a rolling motion, reducing the friction between them and making the relative movement between the connecting arm 120 and the bracket 110 smoother. This improves the reliability and stability of the movement of the connecting arm 120 relative to the bracket 110, thereby improving the reliability and stability of the panel 200 opening or closing the receiving cavity opening. It also reduces wear caused by the direct contact movement between the first guide post 124 and the groove wall of the first guide groove 111, protecting the first guide post 124. If the first bushing 125 wears or is damaged, it can be easily and reliably disassembled and replaced. When the connecting arm 120 reciprocates along the first guide groove 111, the gear and the tooth 123 are always meshed, so that the gear limits the upward movement of the connecting arm 120. Figure 4 As shown, the second gear 1312 is located above the connecting arm 120, thereby limiting the upward movement of the connecting arm 120 as a whole.

[0094] In addition, such as Figure 4As shown, the connecting arm 120 has a second guide groove 126 along the first direction, and the tooth 123 is located on the outer side of the upper groove wall of the second guide groove 126. The bracket 110 has a laterally extending second guide post 113. The gear and the second guide post 113 are arranged opposite to each other in the vertical direction and are spaced apart. The second guide post 113 supports and abuts against the inner side of the groove wall of the second guide groove 126. Both the tooth 123 and the second guide post 113 can act on the upper groove wall of the second guide groove 126, so that the tooth and the second guide post can give two opposite forces to the upper groove wall of the second guide groove, so that the upper groove wall of the second guide groove 126 has a tendency to return to its original position when deformed, thereby improving the reliability of the second guide groove 126 in guiding the connecting arm 120 relative to the bracket 110, and thus improving the reliability of the panel 200 in opening or closing the receiving cavity opening.

[0095] Continue to refer to Figure 4 As shown in an exemplary embodiment, the connecting arm 120 has a second guide groove 126 extending along a first direction. The extension trajectory of the second guide groove 126 matches the extension trajectory of the first guide groove 111, and the second guide groove 126 is located below the tooth 123. The bracket 110 has a second guide post 113, which matches the second guide groove 126. When the tooth 123 is deformed downward by the meshing force of the gear, the second guide post 113 is located in the second guide groove 126 and below the deformed position, which can give the tooth 123 an upward force to correct and reset the deformation of the tooth 123.

[0096] For example, such as Figure 4 As shown, the wall of the second guide groove 126 is at least partially curved in its own extending direction, so that when the connecting arm 120 moves in the second direction, a height difference is formed in the second direction, so as to drive the panel 200 to rise or fall in the second direction, so that the panel 200 opens or closes the receiving cavity opening, which facilitates the removal and placement of the water tank.

[0097] It should be noted that, along the second direction, the gear and the second guide post 113 are arranged opposite each other in the vertical direction, including the complete or partial overlap of the projections of the gear and the second guide post 113 on the same surface in the vertical direction. This allows the two forces exerted by the gear teeth and the second guide post 113 on the upper wall of the second guide groove 126 along the second direction to partially counteract each other, thereby correcting and restoring the deformation of the upper wall of the second guide groove 126 along the second square, and improving the structural guidance of the second guide groove 126.

[0098] For example, such as Figure 4As shown, the gear and the projection portion of the second guide post 113 on the same surface overlap in the vertical direction, that is, in the second direction, the second guide post 113 is located below the second gear 1312, so that the projection portion of the gear and the second guide post 113 overlap in the vertical direction, thereby improving the reliability of the second guide post 113 in correcting and resetting the upper groove wall of the second guide groove 126.

[0099] Since the connecting arm 120 is made of plastic, when the tooth 123 meshes with the second gear 1312, the tooth 123 is subjected to an overall downward force from the second gear 1312. As a plastic part, the contact point between the tooth 123 and the second gear 1312 is prone to deformation. The second guide post 113, located directly below the shaft of the second gear 1312, can apply an upward force to the tooth 123 at the same moment that the tooth 123 deforms, thereby correcting and resetting the deformation at that position, improving the transmission accuracy between the transmission component 131 and the connecting arm 120, and improving the reliability of the second guide groove 126 in guiding the movement of the connecting arm 120 relative to the bracket 110.

[0100] In addition, by setting the second guide post 113 and the second guide groove 126, combined with the setting of the first guide post 124 and the first guide groove 111, the relative movement between the connecting arm 120 and the bracket 110 is controlled by the two guide grooves, which improves the guiding accuracy of the connecting arm 120 when moving relative to the bracket 110, thereby improving the positional accuracy of the panel 200 in the open or closed state, and thus improving the reliability and stability of the movement of the panel 200 relative to the opening of the receiving cavity.

[0101] In another example, the second guide groove 126 is provided on the bracket 110, that is, both sub-brackets 115 are provided with the second guide groove 126 extending in the first direction. The extension trajectory of the second guide groove 126 matches the extension trajectory of the first guide groove 111. The connecting arm 120 has second guide posts 113 on both sides. The second guide posts 113 match the second guide groove 126. The two guide grooves provided in this embodiment can also improve the guiding accuracy of the connecting arm 120 when it moves relative to the bracket 110.

[0102] However, by setting the first guide groove 111 on the bracket 110 and the second guide groove 126 on the connecting arm 120, compared with the above embodiment, the first guide groove and the second guide groove-shaped slot structure are distributed on two different components. This can improve the guiding accuracy of the connecting arm 120 relative to the bracket 110, while also improving the structural strength of the bracket 110 and the connecting arm 120 respectively. This can reduce the number of additional components on the bracket 110 and the connecting arm 120 that need to be set to enhance the structural strength.

[0103] Furthermore, such as Figure 4 As shown, a deformable portion 127 is provided between the second guide groove 126 and the toothed portion 123. A second guide post 113 is disposed within the second guide groove 126 to correct the deformation of the deformable portion 127. The appearance of the deformable portion 127 is a structure created by the second guide groove 126 on the connecting arm 120. Under the force of the transmission member 131, the deformation of the connecting arm 120 is concentrated on the deformable portion 127, and does not act on other parts of the connecting arm 120. This makes it less likely for other parts of the connecting arm 120 to deform and can maintain a stable state. Furthermore, the deformation of the deformable portion 127 is corrected by the reaction force of the second guide post 113, thereby controlling the deformation of the deformable portion 127. This ensures that the entire connecting arm 120 can maintain a stable state, thereby improving the reliability and stability of the connecting arm 120 during the movement of the control panel 200.

[0104] Furthermore, in some embodiments, reference continues to be made to... Figure 4 As shown, a second bushing 114 is fitted onto the second guide post 113, and the second bushing 114 is in direct contact with at least part of the groove wall of the second guide groove 126. This makes the movement between the second guide post 113 and the second guide groove 126 a rolling motion, reducing the friction between them and making the relative movement between the connecting arm 120 and the bracket 110 smoother. This improves the reliability and stability of the movement of the connecting arm 120 relative to the bracket 110, thereby improving the reliability and stability of the panel 200 opening or closing the receiving cavity opening. It also reduces wear on the second guide post 113, protecting it. If the second bushing 114 wears or is damaged, it can be easily disassembled and replaced, and the disassembly is simple and reliable.

[0105] In addition, such as Figure 6 and Figure 7As shown, each of the two sub-supports 115 has a limiting hole 1151. The second guide post 113 passes through the second guide groove 126, and its two ends pass through the limiting hole 1151 respectively. The two ends of the second guide post 113 have limiting structures, which are located outside the sliding gap 112 and abut against the surface of the corresponding sub-support 115. In this way, by setting limiting structures at both ends of the second guide post 113, the distance between the two sub-supports 115 can be further controlled. Combined with the limiting part on the first guide post 124, the distance between the two sub-supports 115 and the connecting arm 120 can be controlled. Thus, during the reciprocating motion of the connecting arm 120 relative to the support 110, the motion trajectory is in the plane formed by the first direction and the second direction, avoiding the movement of the connecting arm 120 in the third direction, that is, avoiding the left and right swaying of the connecting arm 120 along the third direction, thereby avoiding the connecting arm 120 from scraping against the two sub-supports on both sides, and thus improving the reliability and stability of the movement of the connecting arm 120 relative to the support 110.

[0106] For example, the limiting structure is a cover-like structure or a cap-like structure, etc.

[0107] Additionally, return Figure 1 and Figure 2 As shown, in the panel lifting mechanism 100, there are two brackets 110 and two connecting arms 120. The two brackets 110 are spaced apart along the third direction, and one bracket 110 corresponds to one connecting arm 120. The first end 121 of both connecting arms 120 is connected to the panel 200, which increases the force-bearing position of the connection between the panel 200 and the cooking device, thereby improving the stability of the movement of the panel 200 relative to the cavity of the cooking device.

[0108] In this embodiment, the drive unit 130 includes a connector 133 and two transmission members 131. The connector 133 is connected between the two transmission members 131. Each transmission member 131 corresponds to a connecting arm 120. The two transmission members 131 are respectively located above their corresponding connecting arms 120. The drive motor 132 is connected to one of the two transmission members 131 so that one of the two transmission members 131 drives the other of the two transmission members 131 to move through the connector 133.

[0109] In this way, on the one hand, the two transmission components 131 are respectively located above their corresponding connecting arms 120, so that neither transmission component 131 is subjected to the direct force of the panel 200, reducing the stress deformation of the transmission component 131 and making the movement process of the panel 200 opening or closing the cavity opening more reliable and stable; on the other hand, the arrangement of the connecting component 133 and the arrangement of the drive motor 132 being connected to only one of the two transmission components 131 ensures that the movement of the two connecting arms 120 relative to the two supports 110 is synchronized under the drive of the same drive motor 132, thereby improving the reliability and stability of the movement of the panel 200 relative to the cooking equipment cavity.

[0110] For example, the connector 133 is a rod-shaped or shaft-shaped structure, and its two ends are respectively fixedly connected to the two second gears 1312 in the two transmission components 131. The connection methods include, but are not limited to, welding, bolt and nut connection, snap-fit, bonding, pin connection, etc.

[0111] In addition, such as Figure 5 As shown, the panel lifting mechanism 100 also includes a first micro switch 140 and a second micro switch 150. The first micro switch 140 and the second micro switch 150 are respectively disposed at both ends of the first guide groove 111. The first micro switch 140 and the second micro switch 150 are configured to be signal-connected to the control unit in the cooking device. By setting the first micro switch 140 and the second micro switch 150, the first guide post 124 can stop moving in time when it reaches both ends of the first guide groove 111, thereby avoiding damage to the first guide post 124 and improving the service life of the first guide post 124 and the connecting arm 120.

[0112] For example, the first micro switch 140 is disposed on the rear side of the first guide groove 111, and the second micro switch 150 is disposed on the front side of the first guide groove 111. The specific logic of the signal connection between the first micro switch 140, the second micro switch 150 and the control unit is as follows: when the first guide post 124 moves to the rear side of the first guide groove 111, the first guide post 124 triggers the first micro switch 140. The first micro switch 140 sends the position information of the first guide post 124 reaching the rear side of the first guide groove 111 to the control unit, and the control unit outputs a stop signal to the drive motor 132. Similarly, when the first guide post 124 moves to the front side of the first guide groove 111, the first guide post 124 triggers the second micro switch 150. The second micro switch 150 sends the position information of the first guide post 124 reaching the front side of the first guide groove 111 to the control unit, and the control unit outputs a stop signal to the drive motor 132. The setting of the first micro switch 140 and the second micro switch 150 avoids over-driving of the drive motor 132 and over-travel of the first guide post 124, thereby saving energy and improving the protection of the first guide post 124.

[0113] For example, the control unit has a processing mechanism and an execution mechanism. The processing mechanism uses the position information of the first guide post 124 transmitted from the first micro switch 140 and the second micro switch 150 to generate drive information for the drive motor 132. The execution mechanism transmits the drive information for the drive motor 132 to the drive motor 132 so that the drive motor 132 can start or stop running.

[0114] In some embodiments, such as Figure 8 and Figure 9 As shown, the connecting arm 120 has a wire passage groove 128, which is configured to accommodate wires electrically connected to the panel 200. It should be noted that the wires are used for electrical signal connection with the panel 200; therefore, the wires need to move with the panel 200 as the panel 200 opens or closes relative to the receiving cavity opening. For example, the connecting arm 120 includes a connecting arm body 1201 and a wire clamping plate 1202. The wire passage groove 128 is disposed on the connecting arm body 1201. The wires can pass through the wire passage groove 128 and are fixed by the wire clamping plate 1202, thereby preventing the wires from coming out of the connecting arm 120 during the movement of the panel 200 relative to the bracket 110, which could cause wire arrangement chaos or breakage, thus improving the reliability of the panel 200's controllability.

[0115] In summary, the panel lifting mechanism 100 for a cooking device provided in this application includes a bracket 110, a connecting arm 120, and a drive unit 130. Driven by the drive unit 130, the connecting arm 120 moves relative to the bracket 110, causing the panel 200 connected to the connecting arm 120 to open or close relative to the opening of the receiving cavity of the cooking device. Specifically, the bracket 110 extends along a first direction and has a first guide groove 111 extending along the first direction. The first guide groove 111 is at least partially curved in its own extending direction to form a height difference in a second direction. The first end 121 of the connecting arm 120 is exposed outside the bracket 110 and connected to the panel 200. A portion of the structure of the connecting arm 120 is slidably constrained within the first guide groove 111. The connecting arm 120 is constructed... To drive the panel 200 along the extension direction of the first guide groove 111 under the sliding force, thereby driving the panel 200 to reciprocate in the first direction and to rise or fall in the second direction; the drive unit 130 is located close to the connecting arm 120, and the power output end of the drive unit 130 has a transmission member 131. The transmission member 131 is located above the connecting arm 120 and can rotate relative to the connecting arm 120 in the forward or reverse direction, so that the transmission member 131 acts on the connecting arm 120 in its own rotating state to drive the connecting arm 120 to reciprocate relative to the bracket 110, thereby causing the panel 200 connected to the connecting member 133 to reciprocate in the first direction and to rise or fall in the second direction, so as to open or close the opening of the cooking equipment receiving cavity, so as to facilitate the replacement, repair or maintenance of the water tank set in the receiving cavity.

[0116] Furthermore, during this process, the transmission component 131 is positioned above the connecting arm 120. Therefore, the transmission component 131 is not subjected to the direct force of the panel 200, thereby reducing the deformation of the transmission component 131 and improving the reliability and stability of the panel 200 connected to the connecting arm 120 when opening or closing the cooking equipment cavity opening.
