Description

Technical Field

[0001] This utility model relates to the field of kitchen equipment technology, and in particular to a kitchen equipment door opening mechanism and kitchen equipment. 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. Utility Model Content

[0003] This utility model provides a kitchen equipment door opening mechanism and kitchen equipment, so as to at least solve some of the above-mentioned technical problems existing in the prior art.

[0004] In a first aspect, embodiments of this utility model provide a kitchen appliance door opening mechanism, comprising: The mounting bracket assembly has a first slide rail; 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; A drive motor is fixed to the mounting base assembly; 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.

[0005] In an optional embodiment, the slider assembly includes: 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. A push rod, connected to the slider, protrudes from the end face of the slider away from the cam.

[0006] In an optional embodiment, the slider has a mounting cavity, and one end of the push rod is fixed inside the mounting cavity.

[0007] In an optional embodiment, the transmission surface has a grease retention groove for storing grease.

[0008] 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; 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.

[0009] In an alternative embodiment, the two sides of the protrusion are tangent to the cam profile.

[0010] In an optional embodiment, it further includes: 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. 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. 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.

[0011] 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.

[0012] In an optional embodiment, the mounting bracket assembly includes: Support, which has a mounting position; 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 to form an open end, 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.

[0013] In an optional embodiment, the mounting bracket assembly further includes: A guide block having a second guide hole through which the push rod passes.

[0014] Secondly, this utility model embodiment provides a kitchen device, including a housing assembly, a door assembly, and the kitchen device opening mechanism described in this utility model embodiment, wherein the kitchen device opening mechanism is disposed on the housing assembly.

[0015] One embodiment of this utility model has the following advantages or beneficial effects: In the kitchen equipment door opening mechanism of this utility model embodiment, the mounting base assembly can be assembled onto the kitchen equipment. The slider assembly is slidably connected to the mounting base assembly. The drive motor is fixed on the mounting base assembly. The cam is driven by 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. By using a combination of ordinary motor, cam and slider to replace expensive electric actuators or multi-stage linkage mechanisms, the rotational motion is directly converted into a precise linear push stroke, reducing transmission loss and realizing automatic door opening of kitchen equipment with lower cost and simple structure.

Detailed Implementation

[0019] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] 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.

[0021] This utility model embodiment provides a door opening mechanism for kitchen equipment, which is applied to kitchen equipment. The kitchen equipment may include a steam oven, a regular oven, and a steam oven. 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.

[0022] See Figures 1 to 15 The kitchen equipment door opening mechanism of this utility model 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 on the kitchen equipment.

[0023] The slider assembly 2 is slidably connected to the mounting base assembly 1. 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 through the cooperation of the second slide groove 211 and the first slide rail 121.

[0024] 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.

[0025] 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.

[0026] 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 respectively driven by the drive motor 3 and the slider assembly 2. 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 the first position to the second position. The slider assembly 2 acts on the door assembly 200, opening the door assembly 200 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 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.

[0027] 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°.

[0028] In some embodiments, see Figures 1 to 4 The 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 on 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] See Figures 9 to 13 A protrusion 41 is provided at the maximum diameter of the cam 4's profile. See also 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 13When 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] In some embodiments, see Figure 3 The 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.

[0040] See Figure 3The 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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, forming an open end, 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.

[0047] In some embodiments, see Figures 1 to 3The 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.

[0048] See Figure 14 and Figure 15 This utility model provides a kitchen device, including a housing assembly 100 and a door assembly 200, and also includes a kitchen device opening mechanism of this utility model, which is disposed on the housing assembly 100.

[0049] Figure 14 and Figure 15 This diagram illustrates the structure of the kitchen appliance door opening mechanism according to an embodiment of the present invention, showing the door assembly 200 opened to a first angle. The first angle can be 10°.

[0050] 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.

[0051] 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.

[0052] 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.
