Description

Technical Field

[0001] This invention relates to the field of kitchen equipment technology, and in particular to a kitchen equipment door opening mechanism, kitchen equipment, and control method thereof. Background Technology

[0002] Kitchen appliances such as microwave ovens, steam ovens, and grills can achieve automatic door opening. The automatic door opening mechanisms mainly employ two schemes: First, the electric actuator drive scheme, where the door is directly pushed by an electric actuator. However, electric actuators are expensive, take up a lot of space, and are prone to jamming after long-term use. Second, the DC geared motor + linkage mechanism scheme, which has a complex structure, requires multiple stages of transmission components, resulting in high manufacturing costs, high failure rates, and difficult maintenance. Summary of the Invention

[0003] This invention provides a kitchen equipment door opening mechanism, a kitchen equipment, and a control method thereof, to at least solve some of the above-mentioned technical problems existing in the prior art.

[0004] In a first aspect, embodiments of the present invention provide a kitchen appliance door opening mechanism, comprising:

[0005] The mounting bracket assembly has a first slide rail;

[0006] A slider assembly having a second slide groove, wherein the slider assembly and the mounting base assembly are slidably connected through the second slide groove and the first slide rail;

[0007] A drive motor is fixed to the mounting base assembly;

[0008] The cam is connected to the drive motor and the slider assembly respectively. The cam rotates under the drive motor to drive the slider assembly to slide along the first slide rail from the first position to the second position, thereby opening the door assembly of the kitchen equipment from the closed state to the first angle. The distance from the second position to the first position is not greater than the stroke of the cam.

[0009] In an optional embodiment, the slider assembly includes:

[0010] The slider includes a first surface and a second surface facing each other, with two opposing side surfaces and two opposing end surfaces between the first surface and the second surface, and a second groove disposed on the two side surfaces, and the end surface facing the cam having a transmission surface that cooperates with the cam.

[0011] A push rod, connected to the slider, protrudes from the end face of the slider away from the cam.

[0012] In an optional embodiment, the slider has a mounting cavity, and one end of the push rod is fixed inside the mounting cavity.

[0013] In an optional embodiment, the transmission surface has a grease retention groove for storing grease.

[0014] In an optional embodiment, the slider assembly further includes a spring sheet, the first surface or the second surface having a spring sheet mounting groove, and one end of the spring sheet being fixed in the spring sheet mounting groove;

[0015] The cam profile has a protrusion at its maximum diameter. When the maximum diameter of the cam profile abuts against the transmission surface, the protrusion squeezes the spring sheet to undergo elastic deformation. Under the condition that the door assembly is opened to the second angle, the spring sheet pushes the slider assembly to move to the third position. The second angle is greater than the maximum angle at which the door opening mechanism can open the door assembly. The distance from the third position to the first position is greater than the stroke of the cam.

[0016] In an alternative embodiment, the two sides of the protrusion are tangent to the cam profile.

[0017] In an optional embodiment, it further includes:

[0018] A first sensor, disposed on the mounting base assembly, sends a signal indicating that the door closing is complete based on the slider assembly being in the first position.

[0019] A second sensor, disposed on the mounting base assembly, sends a signal to indicate that the door assembly is opened to a first angle based on the slider assembly at the far rest position of the cam.

[0020] Based on the movement of the slider assembly to the third position, the second sensor sends a signal to indicate that the door assembly opens to a second angle.

[0021] In an optional embodiment, the first sensor and the second sensor are micro switches; the slider has a first protrusion for acting on the first sensor and a second protrusion for acting on the second sensor on its side, and the first protrusion and the second protrusion are located on the same side or on different sides.

[0022] In an optional embodiment, the mounting bracket assembly includes:

[0023] Support, which has a mounting position;

[0024] A slide block is provided at the mounting position. The slide block is provided with a first slide rail. At least one end of the first slide rail is open so that the slider can be assembled to the slide block from the open end. The support limits the open end of the first slide rail to prevent the slider from falling off the slide block. The slide block has a first guide hole, and the push rod passes through the first guide hole.

[0025] In an optional embodiment, the mounting bracket assembly further includes:

[0026] A guide block having a second guide hole through which the push rod passes.

[0027] Secondly, embodiments of the present invention provide a kitchen device, including a housing assembly, a door assembly, and a kitchen device opening mechanism as described in the embodiments of the present invention, wherein the kitchen device opening mechanism is disposed on the housing assembly.

[0028] Thirdly, embodiments of the present invention provide a kitchen equipment control method, wherein the kitchen equipment includes a cabinet assembly, a door assembly, and a kitchen equipment door opening mechanism as described in embodiments of the present invention, the method comprising:

[0029] The door opening strategy is determined based on at least one of the following: the door opening command, the operating mode of the kitchen equipment, and the operating parameters of the kitchen equipment.

[0030] The drive motor is controlled to rotate the cam according to the door opening strategy.

[0031] In an optional embodiment, controlling the drive motor to rotate the cam according to the door opening strategy includes:

[0032] Upon receiving the door opening command, the drive motor is controlled to push the cam forward and then stop.

[0033] In an optional embodiment, after the cam has come to a complete stop, the following further step is taken:

[0034] Based on the user manually opening the door assembly, the drive motor is controlled to drive the cam back to its original position and then come to a near stop; or

[0035] Based on the user manually closing the door assembly, the drive motor is controlled to drive the cam back to its original position and then come to a near stop.

[0036] In an optional embodiment, controlling the drive motor to rotate the cam according to the door opening strategy includes:

[0037] Once cooking is complete, the drive motor is controlled to rotate the cam, opening the door assembly to a set angle; or

[0038] Upon completion of cooking, a heat release prompt is issued; if the response to the heat release prompt is yes, the drive motor is controlled to rotate the cam, opening the door assembly to a set angle.

[0039] In an optional embodiment, controlling the drive motor to rotate the cam according to the door opening strategy includes:

[0040] Real-time acquisition of cooking parameters, including at least one of time, cooking temperature, and cooking humidity values;

[0041] Based on the obtained cooking parameters meeting the door opening conditions, the drive motor is controlled to drive the cam to rotate, opening the door assembly to a set angle. The door opening conditions include at least one of the following: the cooking humidity is greater than a first humidity threshold, the cooking time reaches a first time threshold, and the cooking temperature is greater than a first temperature threshold.

[0042] The door assembly remains open until cooking is finished, or, based on the acquired cooking parameters meeting the closing conditions, the drive motor is controlled to rotate the cam to near rest, so that the door assembly closes under the action of the spring hinge. The closing conditions include at least one of the following: the cooking humidity is less than a second humidity threshold, the door assembly is open for a second time threshold, and the cooking temperature is less than a second temperature threshold; wherein, the second humidity threshold is less than the first humidity threshold, and the second temperature threshold is less than the first temperature threshold.

[0043] One embodiment of the present invention has the following advantages or beneficial effects:

[0044] In the kitchen equipment door opening mechanism of this invention, a mounting base assembly can be assembled onto the kitchen equipment. A slider assembly is slidably connected to the mounting base assembly. A drive motor is fixed to the mounting base assembly. A cam is connected to both the drive motor and the slider assembly via transmission. The cam rotates under the drive motor's influence, driving the slider assembly to slide along a first slide rail from a first position to a second position, thereby opening the kitchen equipment door assembly from a closed state to a first angle. The distance from the second position to the first position is no greater than the cam's stroke. By replacing expensive electric actuators or multi-stage linkage mechanisms with a combination of a common motor, cam, and slider, rotational motion is directly converted into precise linear stroke, reducing transmission losses and achieving automatic door opening of the kitchen equipment at a lower cost and with a simpler structure.

Detailed Implementation

[0063] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0064] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended meaning of inclusion and that other elements / components / etc. may exist in addition to the listed elements / components / etc.

[0065] This invention provides a door opening mechanism for kitchen equipment, which can be applied to kitchen appliances. The kitchen appliances may include steam ovens, ovens, and steam ovens. See also... Figure 14 and Figure 15 The kitchen equipment may include a cabinet assembly 100 and a door assembly 200. The door assembly 200 may be hinged to the cabinet assembly 100. In a specific implementation, the door assembly 200 may be hinged to the cabinet assembly 100 via a spring hinge, and the door assembly 200 may close under the action of the spring hinge within a certain opening angle range.

[0066] See Figures 1 to 15 The kitchen equipment door opening mechanism of this embodiment includes a mounting base assembly 1, a slider assembly 2, a drive motor 3, and a cam 4. The mounting base assembly 1 is fixed to the housing assembly 100 to install the door opening mechanism onto the kitchen equipment.

[0067] The slider assembly 2 and the mounting base assembly 1 can be slidably connected via a slide rail and a slide groove. The slider assembly 2 can slide relative to the mounting base assembly 1. The mounting base assembly 1 has a first slide rail 121, and the slider assembly 2 has a second slide groove 211. The slider assembly 2 and the mounting base assembly 1 are slidably connected via the cooperation of the second slide groove 211 and the first slide rail 121.

[0068] The drive motor 3 is fixed to the mounting base assembly 1. The drive motor 3 can be used to provide power to the door opening mechanism.

[0069] Cam 4 is connected to drive motor 3 and slider assembly 2 respectively. Cam 4 rotates under the drive of drive motor 3 to drive slider assembly 2 to slide along first slide rail 121 from first position to second position, thereby opening the door assembly 200 of the kitchen equipment from the closed state to the first angle. See also Figure 13 , Figure 13 The middle cam 4 is at its lowest point, and the slider assembly 2 is in the first position. The distance from the second position to the first position is no greater than the stroke of the cam 4. (See also...) Figure 15 When the stroke from the second position to the first position is equal to that of cam 4, the door opening mechanism opens the door assembly 200 at its maximum angle.

[0070] In the kitchen equipment door opening mechanism of this embodiment, the mounting base assembly 1 can be assembled onto the kitchen equipment. The slider assembly 2 is slidably connected to the mounting base assembly 1. The drive motor 3 is fixed on the mounting base assembly 1. The cam 4 is driven by the drive motor 3 and the slider assembly 2 respectively. The cam 4 rotates under the drive of the drive motor 3, thereby driving the slider assembly 2 to slide along the first slide rail 121 from a first position to a second position. The slider assembly 2 acts on the door assembly 200, opening the door assembly 200 of the kitchen equipment from a closed state to a first angle. The distance from the second position to the first position is not greater than the stroke of the cam 4. By using a combination of a common motor, cam 4, and slider 21 to replace the expensive electric push rod 22 or multi-stage linkage mechanism, the rotational motion is directly converted into a precise linear push stroke, reducing transmission loss and realizing automatic door opening of the kitchen equipment with lower cost and simple structure.

[0071] In this embodiment of the invention, the first angle can be any angle within the maximum angle range that the door opening mechanism can open the door assembly 200. The specific value of the first angle can be set according to specific circumstances. When the cam 4 pushes the slider assembly 2 to move the maximum distance, the door opening mechanism opens the door assembly 200 at the maximum angle. In an exemplary embodiment, the maximum angle at which the door opening mechanism opens the door assembly 200 can be 10°-30°. In specific implementations, the maximum angle at which the door opening mechanism opens the door assembly 200 can be, for example, 10°, 15°, 20°, or 25°.

[0072] In some embodiments, see Figures 1 to 4The slider assembly 2 includes a slider 21 and a push rod 22. The slider 21 is slidably connected to the mounting base assembly 1. See also... Figures 5 to 7 The slider 21 may include a first surface 212 and a second surface 213 facing each other. The first surface 212 or the second surface 213 of the slider 21 faces the mounting surface on the housing assembly 100. Between the first surface 212 and the second surface 213 are two opposing side surfaces 214 and two opposing end surfaces 215. The two end surfaces 215 are perpendicular to the two side surfaces 214. A second groove 211 is provided on the two side surfaces 214. The second groove 211 of the side surface 214 of the slider 21 slides in engagement with a first slide rail 121 on the mounting base assembly 1. The end surface 215 facing the cam 4 has a transmission surface 216 that engages with the cam 4. The profile of the cam 4 abuts against the transmission surface 216.

[0073] The first surface 212 and the second surface 213 are parallel to the sliding plane, which is the plane where the slide rail is located. The two end faces 215 are perpendicular to the slide rail. The two side faces 214 are parallel to the slide rail and perpendicular to the sliding plane.

[0074] Push rod 22 is connected to slider 21 and protrudes from the end face 215 of slider 21 away from cam 4. One end of push rod 22 is connected to slider 21, and the other end acts on door assembly 200 to push door assembly 200 to rotate relative to box assembly 100, thereby opening.

[0075] In some embodiments, see Figure 4 The free end of the push rod 22 may be provided with an end sleeve 23, which is fitted onto the end of the push rod 22. The end sleeve 23 may be made of plastic, rubber, or other materials.

[0076] In some embodiments, see Figure 5 and Figure 6 The slider 21 has a mounting cavity 217, and one end of the push rod 22 is fixed inside the mounting cavity 217. The mounting cavity 217 is provided on the slider 21, and one end of the push rod 22 is embedded in the mounting cavity 217. The push rod 22 can be fixed inside the mounting cavity 217 with screws or the like. The mounting cavity 217 includes a groove and a hole.

[0077] In some embodiments, see Figure 5 The transmission surface 216 has a grease retention groove 218 for storing grease. The grease retention groove 218 on the transmission surface 216 can store grease, thereby maintaining continuous lubrication between the transmission surface 216 and the profile of the cam 4.

[0078] In some embodiments, see Figure 2 and Figure 4 The slider assembly 2 also includes a spring sheet 24, with a spring sheet mounting groove 219 on the first surface 212 or the second surface 213, and one end of the spring sheet 24 is fixed in the spring sheet mounting groove 219.

[0079] See Figures 9 to 13 The cam 4 has a protrusion 41 at its maximum diameter on its profile, see [reference]. Figure 13 When the cam 4, at its maximum diameter, abuts against the transmission surface 216, the protrusion 41 compresses the spring plate 24, causing elastic deformation. Under the condition that the door assembly 200 is opened to the second angle, the spring plate 24 pushes the slider assembly 2 to the third position. The second angle is greater than the maximum angle at which the door opening mechanism can open the door assembly 200, and the distance from the third position to the first position is greater than the stroke of the cam 4. (See also...) Figure 13 When the maximum diameter of the cam 4 abuts against the transmission surface 216 of the slider 21, the slider assembly 2 moves the maximum distance, and the door assembly 200 opens to the maximum angle that the door opening mechanism can achieve under the action of the push rod 22. The protrusion 41 compresses the spring plate 24, causing elastic deformation. When the user manually opens the door assembly 200 further, the spring plate 24 recovers its deformation and pushes the slider assembly 2 to continue moving. For example, if the protrusion protrudes 5mm from the profile, when the cam 4 is at its far rest, the protrusion compresses the spring plate 24 by 5mm. When the door assembly 200 is opened further, the spring plate 24 can continue to push the slider assembly 2 to move by 5mm. At this time, a signal indicating that the door assembly 200 is fully open can be triggered. The control unit of the kitchen equipment can determine the open state of the door assembly 200 based on this signal.

[0080] In some embodiments, see Figures 11 to 13 The two sides of the protrusion 41 are tangent to the contour of the cam 4. The tangency of the protrusion 41 with the contour of the cam 4 helps to dampen the vibration of the spring plate 24. During the push stroke of the cam 4, the protrusion compresses the spring plate 24 along the tangent of the cam 4 contour. When the door assembly 200 closes, for example, the spring hinge's rebound force pushes the door assembly 200 to close, the door assembly 200 presses against the push rod 22 in the opposite direction, the slider 21 retracts close to the cam 4 contour, and the spring plate 24 is released along the tangent of the cam 4.

[0081] In some embodiments, see Figure 9 and Figure 10 The cam 4 has a shaft hole 42 that mates with the output shaft of the drive motor 3. The shaft hole 42 is not circular. In specific implementations, the shaft hole 42 can be an oblong hole or a D-shaped hole.

[0082] In some embodiments, see Figure 10 At least one end of the shaft hole 42 has a clamping surface 43, which is higher than the surface of the cam 4. In a specific implementation, the clamping surface 43 is 0.15-0.3 mm higher than the surface of the cam 4. For example, the clamping surface 43 is 0.2 mm higher than the surface of the cam 4. The clamping surface 43 ensures a firm fit between the cam 4 and the drive motor 3, preventing loosening.

[0083] In some embodiments, see Figure 3The door opening mechanism also includes a sensor for sensing the position of the door assembly 200, which can be mounted on a mounting base. The sensor can determine the position of the door assembly 200 by sensing the slider assembly 2.

[0084] See Figure 3 The sensor may include a first sensor 5 and a second sensor 6, with the first sensor 5 disposed on the mounting base assembly 1. Based on the slider assembly 2 being in a first position, the first sensor 5 sends a signal indicating that closing is complete. When the first sensor 5 detects the slider assembly 2 in the first position, it can determine that the door assembly 200 is in a closed state and can send a signal to indicate that closing is complete.

[0085] The second sensor 6 may be mounted on the mounting bracket assembly 1. See also Figure 3 Based on the slider assembly 2 being at its far-rest position on the cam 4, the second sensor 6 sends a signal indicating that the door assembly 200 has opened to a first angle. When the second sensor 6 detects the slider assembly 2 at the far-rest position on the cam 4, it can determine that the door assembly 200 is open and can send a signal to indicate that the door assembly 200 has opened to the first angle. When the cam 4 rotates to its far-rest point and abuts against the slider assembly 2, the slider assembly 2 pushes the door assembly 200 open to the maximum angle that the opening mechanism can open the door assembly 200 to. The second sensor 6 senses the slider assembly 2 at this position and can send a message indicating that the door assembly 200 has opened.

[0086] Based on the movement of slider assembly 2 to the third position, the second sensor 6 sends a signal indicating that door assembly 200 is opened to the second angle. When the user manually opens door assembly 200, door assembly 200 no longer obstructs slider assembly 2, and spring plate 24 pushes slider assembly 2 to move, disengaging from the sensing of the second sensor 6. At this point, it can be confirmed that door assembly 200 is opened to the second angle. The second sensor 6 can emit low and high levels respectively to represent different signals when it detects slider assembly 2 and when it does not detect slider assembly 2. For example, the second sensor 6 emits a low level when it detects slider assembly 2 and a high level when it does not detect slider assembly 2.

[0087] As slider assembly 2 moves from the third position to the far-rest position of cam 4, second sensor 6 sends a signal indicating that door assembly 200 is closed. When door assembly 200 closes, the spring hinge's restoring force pushes door assembly 200 to close, and door assembly 200 presses against slider assembly 2. Slider assembly 2 presses against spring plate 24, and slider assembly 2 moves to the far-rest position of cam 4. Second sensor 6 detects slider assembly 2 and can send a signal indicating that door assembly 200 is closing, indicating that door assembly 200 is closing. It can then control drive motor 3 to rotate cam 4 to the lowest point, slider 21 retracts close to the contour of cam 4, and the spring hinge's restoring force pushes door assembly 200 to close completely. At this time, slider assembly 2 retracts to the first position and is detected by first sensor 5, indicating that door assembly 200 is closed, and drive motor 3 can be controlled to stop rotating.

[0088] In some embodiments, the first sensor 5 and the second sensor 6 can be microswitches. The side 214 of the slider 21 has a first protrusion 26 for acting on the first sensor 5 and a second protrusion 27 for acting on the second sensor 6, the first protrusion 26 and the second protrusion 27 being located on the same side or different sides. When the door assembly 200 is in the closed state, the slider assembly 2 is in the first position, the first protrusion 26 on the slider 21 touches the first sensor 5, and the first sensor 5 detects the slider 21 in the first position. When the cam 4 moves the slider assembly 2 to the far-rest position, it opens the door assembly 200 to the maximum angle that the opening mechanism can open, the second protrusion 27 on the slider 21 touches the second sensor 6, and the second sensor 6 detects the slider 21, indicating that the door assembly 200 is open. When the user manually continues to open the door assembly 200, the door assembly 200 no longer obstructs the slider assembly 2, and the spring plate 24 pushes the slider assembly 2 to the third position. When the door assembly 200 closes, the spring hinge's rebound force pushes the door assembly 200 to close, the slider assembly 2 presses against the spring plate 24, and the slider assembly 2 moves to its far rest position. The second protrusion 27 then touches the second sensor 6 again. The second sensor 6 detects the slider 21 twice consecutively, which can send a signal to indicate that the door assembly 200 is closing. This indicates that the door assembly 200 is closing, and the drive motor 3 can be controlled to rotate the cam 4 to its lowest point. The slider 21 retracts close to the contour of the cam 4, and the spring hinge's rebound force pushes the door assembly 200 to close completely. At this time, the slider assembly 2 retracts to the first position, the first protrusion 26 touches the first sensor 5, indicating that the door assembly 200 is closed completely, and the drive motor 3 can be controlled to stop rotating.

[0089] In some embodiments, see Figures 1 to 3 The mounting bracket assembly 1 includes a support 11 and a slide 12. The support 11 can be connected to the housing assembly 100. For example, the support 11 can be fixed to the middle layer plate 300 on the upper part of the housing assembly 100. The support 11 has a mounting position.

[0090] Slide 12 is located in the mounting position, see Figure 8 The slide block 12 is provided with a first slide rail 121, at least one end of which is open, so that the slider 21 can be assembled onto the slide block 12 from the open end. The support 11 limits the open end of the first slide rail 121 to prevent the slider 21 from falling off the slide block 12. The slide block 12 has a first guide hole 122 through which the push rod 22 passes. After the slider 21 is assembled onto the slide block 12 from the open end and the slide block 12 is installed in the mounting position, the support 11 closes the open end to prevent the slider 21 from sliding off the slide block 12.

[0091] In some embodiments, see Figures 1 to 3 The mounting bracket assembly 1 also includes a guide block 25, which has a second guide hole through which the push rod 22 passes. By setting the guide block 25 to guide the push rod 22, it can be ensured that the push rod 22 moves linearly along its axial direction.

[0092] See Figure 14 and Figure 15 This invention provides a kitchen appliance, including a cabinet assembly 100 and a door assembly 200, and also includes a kitchen appliance opening mechanism, which is disposed on the cabinet assembly 100.

[0093] Figure 14 and Figure 15 This diagram illustrates the structure of a kitchen appliance door opening mechanism according to an embodiment of the present invention, where the door assembly 200 is opened to a first angle. The first angle can be 10°.

[0094] In an exemplary embodiment, the door opening mechanism may be provided on the middle layer plate 300 on the upper part of the box assembly 100.

[0095] The door assembly 200 may be hinged to the bottom of the housing assembly 100. The opening mechanism pushes the upper part of the door assembly 200 to open the door assembly 200 to a set angle.

[0096] The side of the door assembly 200 may be equipped with a handle pad, which may be made of materials such as plastic. The handle pad may be used for anti-slip and anti-scalding functions.

[0097] This invention provides a method for controlling kitchen equipment. The kitchen equipment includes a housing assembly 100, a door assembly 200, and a door opening mechanism according to this invention. The method of this invention can be implemented by the door opening mechanism described above, and the description of the door opening mechanism can be used to understand the method of this invention. The kitchen equipment control method of this invention includes:

[0098] The door opening strategy is determined based on at least one of the following: the door opening command, the operating mode of the kitchen equipment, and the operating parameters of the kitchen equipment.

[0099] The door opening strategy controls the drive motor 3 to drive the cam 4 to rotate.

[0100] In some embodiments, the drive motor 3 is controlled to rotate the cam 4 according to the door opening strategy, including:

[0101] Upon receiving an opening command, the drive motor 3 is controlled to push the cam 4 forward and then stop. The opening command can be generated by the user through operating the opening button, an app, etc.

[0102] After the kitchen equipment is powered on, it can detect whether the first sensor 5 is triggered. If the first sensor 5 does not detect the slider 21, it indicates that the cam 4 has not rotated to the lowest position, and the door assembly 200 has not closed properly. At this time, the drive motor 3 drives the cam 4 to rotate until the first sensor 5 detects the slider 21, at which point the door assembly 200 is in the closed state. During this process, the buttons for operating the kitchen equipment are ineffective. If the first sensor 5 does not detect the slider 21, after pressing the door open button, an opening command is generated, controlling the drive motor 3 to drive the cam 4 to rotate to the highest point to achieve the push stroke. The protrusion 41 on the cam 4 compresses the spring, causing elastic deformation. The second protrusion 27 on the slider 21 touches the second sensor 6, which can send a signal to indicate that the door assembly 200 is opened to the first angle. In specific implementations, the cam 4 can rotate 180° to reach the highest point.

[0103] In some embodiments, after the cam 4 reaches its far rest position, the process further includes: based on the user manually opening the door assembly 200, controlling the drive motor 3 to drive the cam 4 back to its near rest position. The cam 4 drives the slider assembly 2 to move to its far rest position, and the protrusion 41 on the cam 4 compresses the spring plate 24, causing elastic deformation. When the user manually opens the door assembly 200, the door assembly 200 no longer obstructs the slider assembly 2, and the spring plate 24 pushes the slider assembly 2 to continue moving until the spring plate 24 recovers its deformation. The second protrusion 27 on the slider 21 disengages from contact with the second sensor 6, causing a change in the signal of the second sensor 6. For example, the second sensor 6 changes from a low level to a high level. At this time, the drive motor 3 can be controlled to drive the cam 4 to rotate to its lowest point, achieving the return stroke and near rest. Subsequently, after the user manually closes the door assembly 200 to a certain angle, the door assembly 200 can automatically close under the elastic force of the spring hinge, and the slider assembly 2 will not obstruct the closing of the door assembly 200.

[0104] In some embodiments, after the cam 4 reaches its far rest position, the process further includes: based on the user manually closing the door assembly 200, controlling the drive motor 3 to drive the cam 4 back to its near rest position. The cam 4 drives the slider assembly 2 to move to the far rest position, and the protrusion 41 on the cam 4 compresses the spring plate 24, causing elastic deformation. When the user manually opens the door assembly 200, the door assembly 200 no longer obstructs the slider assembly 2, and the spring plate 24 pushes the slider assembly 2 to continue moving until the spring plate 24 recovers its deformation. At this point, the slider assembly 2 is in the third position. The second protrusion 27 on the slider 21 disengages from contact with the second sensor 6, causing a change in the signal of the second sensor 6. For example, the second sensor 6 changes from a low level to a high level. When the user manually closes the door assembly 200, the door assembly 200 contacts the push rod 22 and presses the push rod 22. The slider 21 further presses the spring plate 24, causing the spring plate 24 to undergo elastic deformation. When the slider assembly 2 returns to the far rest position, the second protrusion 27 on the slider 21 touches the second sensor 6. The second sensor 6 is triggered twice consecutively, indicating that the door assembly 200 is closing. At this time, the drive motor 3 can be controlled to drive the cam 4 to rotate to the lowest point, achieving a return stroke and near rest. After the user manually closes the door assembly 200 to a certain angle, the door assembly 200 can automatically close under the elastic force of the spring hinge. During the rotation of the cam 4, the slider 21 retracts close to the contour of the cam 4. When the cam 4 rotates to the lowest point, the spring hinge's rebound force pushes the door assembly 200 to close completely. At this time, the slider assembly 2 retracts to the first position, and the first protrusion 26 touches the first sensor 5, indicating that the door assembly 200 is closed. The drive motor 3 can then be controlled to stop rotating.

[0105] The operating modes of kitchen equipment can include cooking modes and cooking stages. In practice, operating modes can include baking modes, cleaning modes, dehydration modes, etc., and cooking stages can include cooking in progress and cooking completion.

[0106] In some embodiments, the drive motor 3 is controlled to rotate the cam 4 according to the door opening strategy, including: based on the completion of cooking, controlling the drive motor 3 to rotate the cam 4 to open the door assembly 200 to a set angle. When cooking is complete, the drive motor 3 can be controlled to rotate the cam 4 to open the door assembly 200 to a set angle for venting, preventing steam and heat generated during cooking from hitting the user and affecting the user experience. After venting the door assembly 200 to the set angle, the user can open the door assembly 200 to remove food without being hit by steam or heat, improving the user experience. Furthermore, venting the door can prevent overcooking. When cooking is complete, the door assembly 200 can be opened 5°-15°. For example, the door assembly 200 can be opened 10° for venting.

[0107] In some embodiments, a heat release prompt is issued upon completion of cooking. If the user responds to the heat release prompt in the affirmative, the drive motor 3 rotates the cam 4, opening the door assembly 200 to a set angle. Upon completion of cooking, the door assembly 200 can be automatically opened to release air according to the opening strategy. Alternatively, a heat release prompt can be issued upon completion of cooking, informing the user whether to open the door for air release. If the user responds to the heat release prompt in the affirmative, the drive motor 3 rotates the cam 4, opening the door assembly 200 to a set angle to release steam and heat generated during cooking. The heat release prompt can be displayed on the control panel of the kitchen equipment, providing "yes" and "no" operation options. If the user selects "yes," it indicates a positive response to the heat release prompt. Alternatively, the heat release prompt can be displayed on the kitchen equipment's app, providing "yes" and "no" operation options for the user to operate.

[0108] In some embodiments, controlling the drive motor 3 to rotate the cam 4 according to the door opening strategy includes: acquiring cooking parameters in real time, the cooking parameters including at least one of cooking time, cooking temperature and cooking humidity value.

[0109] Based on the acquired cooking parameters meeting the opening conditions, the drive motor 3 is controlled to rotate the cam 4, opening the door assembly 200 to a set angle. The opening conditions include at least one of the following: cooking humidity exceeding a first humidity threshold, cooking time reaching a first time threshold, or cooking temperature exceeding a first temperature threshold. During cooking, if at least one of the cooking time, cooking temperature, or cooking humidity values ​​reaches its corresponding threshold, the door assembly 200 can be opened to the set angle. Specific cooking parameters can also be combined with cooking modes. Different cooking modes may use different cooking parameters as the opening conditions.

[0110] Cam 4 can rotate 180° to reach its highest point, or it can rotate 90° or other angles without reaching its highest point. In specific implementations, the opening angle of door assembly 200 can be 5° or 10°.

[0111] For some baking modes that require humidity control during the cooking process, the cooking humidity can be selected as the door opening condition. The cooking humidity H inside the cabinet assembly 100 is acquired in real time during cooking. When the cooking humidity exceeds a first humidity threshold, the drive motor 3 is controlled to rotate the cam 4, opening the door assembly 200 to a set angle. The first humidity threshold can be determined based on the specific food being cooked or the cooking process. In an exemplary embodiment, the first humidity threshold could be, for example, 70% RH.

[0112] For some dehydration modes, such as when cooking dried fruit, jerky, or egg rolls, cooking time can be selected as the door opening condition. The cooking time is tracked in real-time during the cooking process. When the cooking time reaches a first time threshold, the drive motor 3 is controlled to rotate the cam 4, opening the door assembly 200 to a set angle. The first time threshold can be determined based on the specific food being cooked or the cooking process.

[0113] For the cleaning mode of kitchen equipment, a high-temperature steam treatment at 125 degrees Celsius can be used for a certain period of time. For example, the high-temperature steam treatment can be performed for 15-30 minutes. During the high-temperature steam treatment, the door assembly 200 can be opened to a set angle according to the set time. For example, the door assembly 200 can be opened and maintained for a certain period of time at 20 minutes and 30 minutes of high-temperature steam treatment. For example, the door assembly 200 can be opened for 1 minute.

[0114] In an exemplary embodiment, the cleaning mode may further include drying, wherein after a preset time of high-temperature steam treatment, the device is dried with hot air for a certain period of time, and after drying, the door assembly 200 is opened to a set angle to expel the hot air. In a specific implementation, this may involve drying with 125-degree hot air for 15 minutes after high-temperature steam treatment.

[0115] In some embodiments, the door assembly 200 remains open until cooking is complete. For example, when cooking dried fruit, jerky, egg rolls, or similar foods, the door assembly 200 can remain open at a set angle until cooking is finished. Maintaining the set angle throughout the cooking process allows for fully automatic cooking and humidity control.

[0116] In some embodiments, based on the acquired cooking parameters meeting the closing conditions, the drive motor 3 is controlled to rotate the cam 4 to near rest, so that the door assembly 200 closes under the action of the spring hinge. The closing conditions include at least one of the following: the cooking humidity is less than a second humidity threshold, the door assembly 200 is open for a second time threshold, or the cooking temperature is less than a second temperature threshold. The second humidity threshold is less than a first humidity threshold, and the second temperature threshold is less than the first temperature threshold. The door assembly 200 can be opened multiple times during the cooking process to achieve automatic cooking.

[0117] In an exemplary embodiment, for some baking modes that require humidity control during the cooking process, the cooking humidity can be selected as the door opening condition. The cooking humidity H inside the cabinet assembly 100 is acquired in real time during cooking. When the cooking humidity is greater than a first humidity threshold, the drive motor 3 is controlled to rotate the cam 4, opening the door assembly 200 to a set angle. When the cooking humidity is less than a second humidity threshold, the cam 4 is controlled to rotate to its lowest point, closing the door assembly 200 under the action of the spring hinge. The door assembly 200 is reopened when the first humidity threshold is reached, and this process is repeated.

[0118] In some embodiments, the door assembly 200 can be closed after the opening time reaches a second time threshold. The second time threshold can be a preset value or a value calculated based on relevant parameters. In an exemplary embodiment, the second time threshold T is calculated using the following formula: T = (100H – 50) / 5, where H is the first humidity threshold and T is in seconds. For example, when the first humidity threshold is 70%, the door assembly 200 is opened for 4 seconds and then closed. When the first humidity threshold is 80%, the door assembly 200 is opened for 6 seconds and then closed. Different foods have different first humidity thresholds, and the opening time of the door assembly 200 also varies.

[0119] In some embodiments, during the process of the door opening mechanism opening the door assembly 200, the drive motor is controlled to stop rotating based on a received pause command. The pause command can be generated by the user through button operation or an app.

[0120] In some implementations, upon receiving a door-closing command, if cam 4 has not rotated to its highest point, the drive motor 3 is controlled to rotate in the opposite direction. If the cam reaches or exceeds its highest point, the drive motor 3 is controlled to continue rotating in the forward direction. The door-closing command can be generated by the user via button operation or an app.

[0121] In some implementations, during the process of the door opening mechanism opening the door assembly 200, based on the received door closing command, the drive motor 3 is controlled to stop rotating and rotate in the opposite direction. The door closing command can be generated by the user through operating buttons or an app.

[0122] When the drive motor 3 needs to change direction during rotation, it brakes for a set time before changing direction. This prevents impact.
