The embodiment shown in fig. 1 provides a kitchen robot 1 capable of automatically cooking food, relieving human energy from a heavy cooking labor process, and enjoying healthy food. The kitchen robot 1 mainly includes a base 2, a cooking unit 3 on the base 2, a charging unit 4 above the cooking unit 3, and a support arm unit 5 for being located at a side of the cooking unit 4.

Wherein the base 2 has a horizontal table 201 for supporting the cooking unit 3. The mesa 201 is substantially square, although in other embodiments, the mesa 201 may have other shapes, such as circular, triangular, etc. The table-board 201 is made of explosion-proof glass, and has the functions of safety protection and convenient cleaning.

As shown in fig. 1, 2 and 3, the base 2 further includes a receiving cavity 202 and supporting legs 203 below the table 201. The receiving cavity 202 is mainly used for receiving electronic circuit components and wires connecting the components. In this embodiment, since the electronic circuit components generate a large amount of heat during operation, the heat dissipation structure 204 is disposed in the accommodating cavity 202. The heat dissipation structure 204 may include a fan, a heat dissipation hole, and the like. In addition, the receiving cavity 202 is provided with an interface 205 for connecting a power line. The interface 205 is located on a side wall of the receiving cavity 202. The power cord may be connected to an external AC power source for providing the energy required by the cooking or control circuit. Of course, in other embodiments, a battery pack may be disposed in the receiving cavity 202, and the battery pack may be used to provide power. And further, the battery pack may be removable for replacement and maintenance.

The support legs 203 of the table 201 are used to support the base 2. The supporting legs 203 have a certain height, so that when the base 2 is horizontally placed on a table top, the bottom of the accommodating cavity 202 has a certain space interval with the table top, and the carrying can be more convenient and the heat dissipation effect is better. In this embodiment, the height of the supporting legs 203 can be adjusted, so that the height of the base 2 can be adjusted within a certain range according to the actual use scene. In addition, in this embodiment, the number of the supporting legs 203 is 4, and the supporting legs 203 are respectively distributed on 4 circles of the base to play a role of uniform support. When not in use, the support legs 203 can be detached from the base 2, and the base 2 can be erected for storage.

In this embodiment, the electronic circuit components in the accommodating cavity 202 of the base 2 may include a main control circuit board. In one embodiment, the electronic circuit components may also include various sensors, such as temperature sensors, current sensors, magnetic sensors, and the like. The main control circuit board can receive instructions of external users or sensing signals sent by various sensors to send corresponding control signals, and the purpose of controlling the kitchen robot 1 to automatically work is achieved.

As shown in fig. 1, the base 2 is further provided with a control switch 206, a metering unit 207, and a display panel 208. The control switch 206 is used to input a control instruction to the kitchen robot 1. In order to achieve better user operation experience, the control switch 206 may be operated by being pressed in the longitudinal direction and also rotated in the circumferential direction. Of course, the present embodiment is not limited to these operation modes, and may also have various interaction modes such as a common push rod sliding mode, a vibration feedback mode, a touch mode, and the like. The metering unit 207 is used for metering and weighing some main materials or auxiliary materials, so that standardized production of dishes is facilitated. In this embodiment, the metering unit 207 has a measuring cup, and the main material or the auxiliary material can be placed in the measuring cup. And a weighing module is arranged at the position of the base 2 where the measuring cup is correspondingly placed. When the equivalent weight cup is placed at the designated position of the base, the weighing module can weigh the weight and feed the weight back to the main control circuit board. And the display panel 208 is used to display information of the kitchen robot. In the present embodiment, the display panel 208 is a strip shape, so that more information can be displayed. In addition, for better interaction, the control switch 206, the metering unit 207 and the display panel 208 are located on the side of the table top, and on the side closer to the user. A display panel 208 is located intermediate the control switch 206 and the metering unit 207. The control switch 206 and the metering unit 207 are located at the top corner of the panel 2.

The cooking unit 3 is mounted on the top 201 of the base 2. The cooking unit main 3 includes a base 301, a pot 302, and a pot cover 303. The base 301 is used for supporting the pan 302, so that the pan 302 can be stably placed on the base 301. The base 301 has a recess to receive a portion of the pan 302, with the recess having a support surface that matches the surface of the pan. In this embodiment, the support surface is formed by a continuous smooth curved surface forming a certain arc.

In addition, the base 301 further includes a heating assembly 304. When the pan 302 is placed on the base 301, the heating assembly 304 may heat the pan 302. In this embodiment, the heating assembly 304 is an electromagnetic coil, and the electromagnetic coil is wound around the electromagnetic coil, and the electromagnetic coil generates magnetic radiation to heat the pan 302 when operating. The electromagnetic coil is substantially annular. The electromagnetic wire coil is fixed on the back of the base 301. The back of the base 301 is provided with latticed positioning ribs, and the electromagnetic wire coil is fixed on the back of the base through the positioning ribs. In other embodiments, the heating assembly 304 may also be other heating methods known to those skilled in the art, for example, the heating assembly may also be a heating wire assembly, and the heat energy generated by the heating wire after being electrified is used to directly heat the pot. In this embodiment, the main control circuit board electrical control passes through the electric current size of electromagnetic wire coil to the temperature of pot heating is given in corresponding control. In other embodiments, the main control circuit board may also control the temperature by controlling other parameters such as voltage. This has the advantage that the heating can be quantified and the data used to characterize the degree of heating can be used for precise control purposes.

As seen in FIG. 2, a temperature sensing assembly 305 is provided at the bottom of the recess. Temperature sensing component 305 senses the current temperature of pan 302 for feedback by direct contact with pan 302. So that the temperature can be correspondingly controlled and adjusted according to the current temperature of the pan 302 measured in real time. For example, when dishes need to be fried, the heating temperature of the heating assembly can be adjusted through the main control circuit board or other control modes, and the pan 302 is heated. The temperature measuring component 305 detects the temperature of the pan in real time, and when the temperature of the pan 302 reaches the preset heating temperature, the main control circuit board or other control modes can adjust the heating temperature of the heating component 304 again according to the real-time feedback of the temperature measuring component 305, so that the temperature of the pan 302 is maintained at the current level.

The bottom of the recess may also be provided with a safety feature to prevent the occurrence of some accidental or uncontrollable element. For example, when the temperature measuring component measures that the current temperature of the pan exceeds a warning temperature, the safety component can feed back and send out a warning signal, so that the main control circuit board or other control modes can cut off the circuit in time, and the safety of a user is guaranteed. In this embodiment, the safety component is a fuse. The fuse is connected in the circuit, thereby when the temperature is higher than fusing temperature, fuse fusing circuit guarantees circuit safety in utilization.

In this embodiment, the base 301 is fixedly mounted on the base 2. Specifically, the base 301 is mounted on the table 201 of the base 2 and protrudes from the plane of the table 201. And the base has an annular side surface, so designed to provide a simpler layout for electrical connection of the heating element and the electronic circuit components contained in the base.

The pan 302 generally includes a pan bladder 306 and a handle 307 for grasping. The pot liner 306 is concave and has a smooth curved surface. The smooth curved surface of the pot liner 306 is matched with the supporting surface of the base, so that the pot liner 306 can be stably supported on the base 301. The heating component 304 mainly concentrates the heating part of the pan 302 on the pan container 306, so that dishes in the pan container 306 are fully heated, and the heating efficiency is improved. It should be noted that in this embodiment, the rim of the pot container 306 has a ring of skirt structure 308 protruding outward, so that the outer surface of the pot container 306 and the skirt structure 308 form a step, thereby facilitating the stable placement of the pot 302 on the base 301. Preferably, the skirt structure 308 is dimensioned by a reasonable design such that the side surface of the skirt structure 308 and the side surface of the base 301 together constitute a smooth surface. In this embodiment, the radius of the skirt structure 308 is larger and the radius of the seat 301 is smaller, so that the side surfaces of the skirt structure 308 and the seat 301 form an inverted conical side surface. Of course, in other embodiments, the skirt structure 308 and the side surface of the seat 301 may also together form a cylindrical side surface, i.e., the radius of the skirt structure and the radius of the seat are substantially the same.

In this embodiment, the handle 307 of the pan 302 is also provided on the side surface of the skirt structure 308. The handles 307 are two in number and symmetrically disposed on opposite sides of the pan 302. The user can conveniently grasp the handle 307 to lift the pan 302 from the base 301. Of course, in other embodiments, the number of handles 307 may also be one, i.e. the user grips the handles from one side. In addition, the handle 307 may be connected in various ways. In this embodiment, the handle 307 is fixedly attached to the skirt structure 308 such that the handle 307 is not removable with respect to the pan 302. The means of securing the connection may also be a screw lock or other conventional means. Of course, the handle 307 may be configured to be movable, and particularly, the handle 307 may be foldable or rotatable so that it may be stowed away to reduce volume when not in use.

The pot cover 303 is used for covering the upper part of the pot 302, so that dishes in the pot container 306 are basically isolated from the outside. The pan cover 303 is provided separately from the pan 302 without a connecting structure therebetween. In this embodiment, the lid 303 can be automatically opened and closed by a control command, thereby avoiding manual operation, improving the experience of the user, and reducing potential hazards. The details of how the control command is passed will be described later. The lid 303 has at least two states. In one state shown in fig. 3, the lid 303 covers the pot 302 and is in contact with the pot 302, i.e. the lid 303 is in a closed state. In another state as shown in fig. 4, the pot cover 303 is not in contact with the pot 302, i.e., the pot cover 303 is in an open state, and dishes can be taken out of the pot 302 or put into the pot 302. As shown in fig. 5, the pot cover 303 is made of tempered glass, which can ensure visibility of domestic food, safety, and prevent the food or hot oil in the pot from splashing out. In addition, the surface of the pot cover 303 can be further provided with a safety hole 309, and the safety hole 309 has a pressure relief function, so that when the pot cover 303 covers the pot 302, the pressure in the pot 302 can be kept safe. In a preferred embodiment, the safety aperture 309 may also be provided with a similar louvered configuration.

The arm unit 5 is mainly used to provide a support function when the lid 303 is opened and closed. The arm unit 5 includes a support arm 501 and a rotation arm 502 that are relatively rotatable. The arm unit 5 thus controls the lid to be rotated open and closed. In this embodiment, the support arm 501 is fixedly disposed. The rotating arm 502 is rotatable about an axis relative to the support arm 501. Wherein the axis is generally horizontal and relatively perpendicular to the longitudinal axis of the lid 303 when the lid 303 is placed on the pot 302. In addition, the rotation range of the rotation arm 502 with respect to the support arm 501 is 60 degrees.

The support arm 501 is fixedly arranged on the base 2. In particular, the support arm 501 is located near the base 301 of the table 201, on one hand the support arm 501 does not affect the normal use of the pot 302 on the base 301, and on the other hand the support arm 501 is used to provide a height that facilitates the control of the pot lid 303. In this embodiment, the support arm 501 fits the base. Specifically, the base 2 is centered on the base, having one side close to the user and the other side remote from the user. To reduce interference, the support arm 501 is located on the other side from the user.

The arm unit 5 has a power unit for driving the movement of the lid. The power unit mainly comprises a first motor 503 located within the support arm 501. The first motor 503 is used for driving the rotating arm 502 to rotate relative to the supporting arm 501. The first motor 503 is disposed in the longitudinal direction. The axis of rotation of the first motor 503 is parallel to the longitudinal axis of the lid 303. Such that the lateral dimension of the support arm 501 is smaller than its longitudinal dimension. Since the output 504 of the power unit is connected to the support arm 501, the support arm 501 is driven to rotate around a horizontal axis. A transmission 523 is therefore also provided between the output 504 and the first motor 503. The transmission 523 converts the longitudinal rotational drive of the first motor 503 into an axial rotation of the output end 504 in the horizontal direction. Meanwhile, the output end 504 is considered to drive other structures such as the pot cover 503 to rotate, which requires a larger torque, so that the transmission mechanism 523 can also improve the output torque through a reasonable reduction ratio design. The transmission 523 may be a worm gear assembly or a planetary bevel gear, etc. as is common in the art.

In this embodiment, the power unit transmits power to the rotary arm through a form-fitting manner. Specifically, the output end 504 has a power surface 505, the support arm 502 has a driven surface 506, and the power surface 505 is coupled with the driven surface 506 for power transmission. The power surface 505 and the driven surface 506 are flat surfaces, and contact and fit with each other to realize power transmission, and when the two are separated from contact, the power connection is disconnected.

As shown in fig. 6 and 7, the output 504 of the power unit has a kidney-shaped configuration. In other words, the output end 504 has a horizontal axis of rotation, and the projection of the output end 504 in a cross-sectional plane perpendicular to this axis is kidney-shaped. Specifically, the kidney-shaped configuration includes a pair of linear edges 507 and a pair of arcuate edges 508. Wherein the straight edges 507 are arranged in parallel at a certain distance, and the arc-shaped edges 508 are arranged oppositely and between the straight edges 507, and the arc-shaped edges 508 are protruded outwards. The length of the straight edge 507 is greater than the radius of the curved edge 508 so that the overall waist-type configuration has an elongated profile. And further, the straight edge 507 is tangent to the curved edge 508. Of course, in other embodiments, the output end 504 may have other configurations, such as a triangular or hexagonal configuration. Further, the center line of the waist-shaped structure is arranged horizontally, and the center line is arranged to overlap the rotation axis. The middle of the kidney-shaped configuration also has an opening for connecting a transmission, through which the centre line and the axis of rotation likewise pass. Wherein the projection of the dynamic surface 505 in the cross-sectional plane coincides with the straight line side.

Correspondingly, the pivot arm 502 has a waist-shaped connector 509 to mate with the waist-shaped configuration of the output. Specifically, a kidney connector 509 is located at one end of the swivel arm 502, particularly near one end of the support arm 501. The kidney connector 509 is connected to the outer periphery of the kidney configuration of the output end 504 such that the kidney connector 509 rotates synchronously with the kidney configuration of the output end 504. The other end of the rotating arm 502, i.e. the end far away from the supporting arm 501, is provided with a first clamping part 510 connected with the pot cover 303. The first engaging portion 510 and the lid 303 have a quick-release function. As shown in fig. 5, the pot lid 303 has a mounting opening 310 in the center, and the central axis of the pot lid 303 penetrates through the mounting opening 310. The mounting opening 310 of the pot cover 303 is provided with a second clamping portion 311. The second click portion 311 has a projection in the circumferential direction around the center axis. And the first clamping portion 510 of the rotating arm 502 is provided with a sliding groove 511 in the circumferential direction. And further, the end of the sliding slot 511 is also provided with a sliding slot inlet, and the opening direction of the sliding slot inlet is perpendicular to the extending direction of the sliding slot 511 or forms a certain angle with the extending direction. The protrusion can move along the circumferential direction after entering the sliding slot 511 from the sliding slot entrance to realize the positioning function. Of course, in other embodiments, the first engaging portion 510 may be provided with a protrusion, and the second engaging portion 311 may be provided with a sliding groove. In the actual use process, the pot cover 303 is close to the first clamping portion 510 of the rotating arm 502, and the first clamping portion 510 is allowed to partially pass through the opening in the center of the pot cover 303, so that the protrusion on the second clamping portion 311 aligns with the sliding slot 511 on the first clamping portion 510. Then, the pot cover 303 is rotated along the central axis, or the pot cover is rotated along the first direction relative to the second clamping portion 311, so that the protrusion slides into the sliding groove 511 to realize clamping, and the pot cover 303 is fixed on the rotating arm 502. When the pot cover 303 is detached from the rotating arm 502, the pot cover 303 is rotated in the opposite direction, or the pot cover 303 rotates along the second direction relative to the second clamping portion 311, and the second direction is opposite to the first direction, so that the protrusion pushes the sliding groove 511 to separate from the rotating arm 502, and the pot cover 303 is separated from the rotating arm 502, and the pot cover 303 is convenient to store or clean. In this embodiment there are 3 sets of circumferential projections and runners forming a fit. And the 3 groups are evenly distributed in the circumferential direction. In other embodiments, there may be other numbers of sets of protrusions and runners, such as 1, 2, or 4 sets, etc.

As shown in FIG. 7, the waist-type connection of the pivot arm has a driven face for mating with a power face. In this embodiment, the kidney type connection has at least two driven faces, a first driven face 512 and a second driven face 513. The dynamic surface may be selectively coupled to one of first driven surface 512 and second driven surface 513. When normal power transmission is performed, namely the output power of the output end 504 drives the pot cover 303 to rotate, the power surface 505 is matched with the first driven surface 512. When normal power transmission is terminated, i.e. output end 504 stops outputting power, power face 505 moves away from engagement with first driven face 512 and engages with second driven face 513. When the power face 505 and the first driven face 512 are mated, as shown in figure 7, there is a first gap 514 between the power face 505 and the second driven face 513. And when the power face 505 is mated with the second driven face 513, there is a second clearance 515 between the power face 505 and the first driven face 513. Both the first driven face 512 and the second driven face 513 are planar. And they are connected to each other and at an angle such that the power face 505 can be switched from mating with one driven face to mating with the other in a rotational position. The included angle between the first driven surface 512 and the second driven surface 513 facing away from the power surface is an obtuse angle, and is preferably about 170 degrees in the present invention. And the included angle between first driven face 512 and second driven face 513 in the direction of the power face is an angle greater than 180 degrees. The projected length of power surface 505 in the cross-sectional plane is greater than the projected length of first driven surface 512 in the cross-sectional plane. Of course, the projected length of the dynamic surface 505 in the cross-sectional plane is also greater than the projected length of the second driven surface 513 in the cross-sectional plane. This facilitates the switching of the power surface between mating driven surfaces.

In addition, to mate with the output end, the kidney connector 509 also has an arcuate profile 516 to mate with the arcuate edge 508 of the output end 504. The degree of curvature of the curved profile 516 and the curved edge 508 remain consistent. Arcuate profile 516 also has an arcuate length that is greater than the arcuate length of arcuate edge 508 so that arcuate edge 508 remains generally flush with arcuate profile 516 during a transition of powered surface 505 from first driven surface 512 to second driven surface 513. As shown in fig. 7, the first driven face 512, the second driven face 513 and the arcuate profile 516 of the kidney-shaped connector 509 are connected in series. Connecting the ends of first driven face 512 are respectively a second driven face 513 and an arcuate profile 516, connecting the ends of second driven face 513 are respectively arcuate profile 516 and first driven face 512, and connecting the ends of arcuate profile 516 are respectively first driven face 512 and second driven face 513.

Since the pot cover 303 has a closed position for closing the pot 302 and an open position for opening the pot 302 relative to the pot 302, the rotating arm 502 drives the pot cover 303 to rotate and switch between the closed position and the open position. For better control of the effect, the kitchen robot 1 also has trigger switches 517 corresponding to the off position and the on position, respectively. When the rotating arm 502 rotates to the corresponding position, the corresponding trigger switch 517 is triggered. The rotating arm 502 has a protrusion 518 thereon, and the protrusion 518 can contact and trigger the trigger switch 517, so as to generate a trigger signal accordingly. As shown in fig. 3, in the present embodiment, the number of the trigger switches 517 is 2, the 2 trigger switches 517 are respectively distributed along the upper and lower directions, and when the lug 518 rotates to the trigger switch 517 corresponding to the open position, the trigger switch 517 sends out a trigger signal indicating that the lid 303 is located at the open position at this time. When the lug 518 rotates to the trigger switch 517 corresponding to the closed position, the trigger switch 517 sends a trigger signal indicating that the lid 303 is in the closed position. Both the trigger switch 517 and the lug 518 are disposed in the interior cavity of the support arm 501. In other embodiments, two lugs and a trigger switch may be provided to cooperate. The support arm 501 also has a fixing rib in the inner cavity for fixing the position of the trigger switch and the first motor 503. The lugs 518 are preferably disposed on the kidney-shaped connector 509 of the pivot arm 502 to ensure that the lugs 518 and the driven surface 506 rotate synchronously.

The use scenario of the power unit driving the pot cover 303 is as follows: when a user wants to close the pot cover 303 or automatically control to close the pot cover 303 by a program, software, or the like, the first motor 503 starts to output a rotating power, and at this time, since the power surface 505 of the output end 504 and the first driven surface 512 of the rotating arm 502 are in a matching and fitting state, the first motor 503 drives the rotating arm 502 and the pot cover 303 connected thereto to rotate in a direction toward a closed position. This state is maintained until the tab 518 on the rotating arm 502 triggers the trigger switch 517. The trigger switch 517 generates a signal to make the kitchen robot 1 determine that the pot cover 303 is closed in place, thereby controlling the first motor 503 to be closed and stopping power output. The power surface 505 of the output end 504 also immediately stops rotating. When considering the situation that some error exists in the actual process, for example, the reason of tolerance or time delay control, when the first motor 503 stops rotating, the pot cover 303 is not completely closed. In order to improve the precision and enable the pot cover 303 to be completely closed in place, the rotating arm 502 is provided with a first driven surface 512 and a second driven surface 513. When the power surface 505 stops rotating, the rotating arm 502 can continue to move for a short distance by the gravity of the lid 303 or the inertia of the rotation, or a factor known or anticipated by those skilled in the art, so that the driven surface 506 coupled with the power surface 505 is switched from the first driven surface 512 to the second driven surface 513. Therefore, after the rotation of the first motor 503 is stopped, the rotating arm 502 and the pot cover 303 move forward by a stroke, so as to achieve the purpose of completely closing the pot 302.

In addition, due to differences of different kitchen robots 1 or the same kitchen robot 1 may not ensure complete consistency in the process of repeatedly closing the pot lid 303. For example, when a kitchen robot 1 performs an action of closing the lid 303 at a certain time, the lid 303 may be already closed when the motor is stopped. When another action of closing the lid 303 is performed, the lid 303 needs to advance by a certain stroke after the motor is stopped. Now, a certain margin is left for the design of the two driven surfaces on the rotating arm 502, so that the pot cover can be accurately closed in place on more occasions. And when the pot cover 303 is closed to travel for the last stroke, the rotating arm 502 and the output shaft 504 are disconnected in power connection, so that the motor is protected, and the motor is prevented from being damaged due to the fact that possible overlarge torque force is generated.

The utility model discloses a kitchen robot except can opening automatically and closing the pot cover, still has the function of automatic interpolation condiment. As shown in fig. 1, the kitchen robot 1 has a charging unit 4 in addition to a cooking unit 3. The dosing unit 4 is used to perform automatic dosing of seasoning into the pan 302. As shown in fig. 1, 2 and 9, the charging unit 4 is entirely located above the pot lid 303. In a preferred embodiment, the feeding unit 4 is located directly above the lid 303, i.e. the centre line of the feeding unit 4 coincides with the centre line of the lid 303. The pot cover is provided with a blanking port 312, the blanking port 312 is eccentrically arranged relative to the center of the pot cover 303, and the blanking port 312 and the central opening of the pot cover 303 are designed in such a way that interference and conflict cannot occur. The opening of the blanking opening 312 is arranged upward. The feeding unit 4 has a discharge port with an opening facing downward. When the feeding unit 4 is in a proper position, the blanking port 312 and the discharge port are aligned, and the seasoning in the feeding unit 4 enters the pot from the blanking port 312 and the discharge port due to gravity, thereby completing the feeding.

In the present embodiment, the charging unit 4 includes a charging cassette 402 and a driving mechanism 420 that drives the charging cassette. The loading box 402 is provided with a seasoning cavity 403 for storing seasoning. The driving mechanism 420 for driving the loading cassette 402 and the power source for driving the rotating arm 502 and the lid 303 are different. Here, the drive mechanism 420 is used to drive the loading cassette 402 individually. The drive mechanism 420 basically includes a second motor 425 and a transmission mechanism. The second motor 425 drives the loading cartridge 402 to perform a rotational motion via a transmission mechanism. And further, the loading cartridge 402 is always rotated about a rotational axis. Wherein the rotation axis of the feeding box 402 is arranged in parallel with the center line of the pot cover 303. In other words, the axis of rotation of the cartridge 402 is longitudinally disposed. In a preferred embodiment, the axis of rotation of the cartridge 402 coincides with its centerline, i.e., the cartridge 402 rotates about its centerline. Thus, the pod 402 may be controlled by the drive mechanism 420 to rotate to a rotational position in which the drop port 312 and the exit port are aligned so that seasoning exits the pod into the pan. In this embodiment, the loading box 402 has a plurality of seasoning chambers 403 independently installed from each other because many seasonings are required for cooking one dish and it is not desirable to mix them with each other to cause taint of taste. Thus, the loading cassette 402 in this embodiment may have multiple rotational positions, and each of the seasoning cavities 403 may be aligned with the discharge port and the blanking port 312 in the corresponding rotational position.

As shown in fig. 9, the loading cassette 402 is mounted on a rotating arm. Specifically, the loading cassette 402 is mounted on the end of the rotating arm 502 remote from the support arm 501. The entire center portion of the rotating arm 502 has a certain thickness, and at the end portion, the rotating arm 502 has a flat support plate 519, and the thickness of the support plate 519 is much smaller than that of the entire rotating arm 502. The support plate 519 has two opposite sides. The cartridge 402 is mounted on a support plate 519, and the lid 303 is also mounted on the support plate 519. When the loading cassette 402 is mounted on the support plate 519, the loading cassette 402 and the support plate 519 are formed to have a thickness substantially equal to the thickness of the entire central portion of the rotary arm 502. In addition, the loading cassette 402 is positioned on one side of the support plate 519, and the lid 303 is positioned on the other side opposite to the support plate 519. The support plate 519, which is part of the rotating arm 502, is thus sandwiched between the lid 303 and the feeding unit 4. The first catching portion 510 is located on the other side of the supporting plate 519 to cooperate with the second catching portion 311 of the lid 303, so that the lid 303 is detachably mounted on the other side. The cartridge 402 is also detachably mounted on the support plate 519. The support plate 519 is a substantially circular disk, the first clamping portion 510 is disposed around the center of the circular disk, and after the second clamping portion 311 on the mounting opening of the pot cover 303 is clamped with the first clamping portion 510 in a matching manner, the center of the circular disk substantially coincides with the center of the pot cover 303.

For more convenient disassembly and assembly and cleaning, the loading box 402 and the support plate 519 are magnetically attracted to each other. The abutment between the cartridge 402 and the support plate 519 is magnetically attracted to each other after installation. When the user needs to separate the two parts, the two parts can be separated by only overcoming the magnetic adsorption force, so that the separation is very convenient. As shown in fig. 9, a protrusion 520 is provided on the support plate 519, and the loading cassette 402 is fittingly mounted on the protrusion 520. The protrusion 520 is symmetrically disposed about the center of the support plate 519, and after the loading cartridge 402 is mounted to the protrusion 520, the center of the loading cartridge 402 also substantially coincides with the center of the support plate 519. So that the center lines of the lid 303, the support plate 519, and the lid 303 substantially coincide. The protrusion 520 is provided with a magnetic material 521, and the cartridge 4 is also provided with a magnetic material. For uniform adsorption, the magnetic material 521 on the protrusion 520 is annular and passes right through the center line of the lid 303.

As shown in fig. 10, the cartridge 402 has an overall shape of a cylinder with a certain thickness. The loading cassette 402 includes a lid and a body 404 disposed within the lid. The lid is located the periphery of reinforced box 402, plays the effect of parcel protection, and its inside cavity forms accommodation space. The body 404 is located in the accommodating space. The body 404 is mounted to be driven in a rotational motion. While the cover is stationary. The body 404 is rotatable relative to the cover. In addition, the feeding box 402 can be quickly and detachably mounted with the supporting plate 519 on the rotating arm 502, and the cover and the body 404 inside the feeding box 402 can be quickly and detachably mounted, so that daily maintenance and cleaning are facilitated.

In this embodiment, the cover body includes an upper cover 405 and a lower cover 406 which are separately provided. The upper cover 405 and the lower cover 406 cooperate to form a receiving space. When mounted, the upper cover 405 covers the upper side of the body 404, and the lower cover 406 covers the lower side of the body 404. When disassembled, the upper cover 405 and the lower cover 406 are separated, and the body 404 in the receiving space can be easily taken out. In other embodiments, the cover may have various forms, for example, the cover may have 3 pieces spliced together, or the cover may be integrally formed. The lower cover 406 is supported on a support plate 519. The lower cover 406 mainly comprises an annular side wall 407 and a circular bottom 408. The side wall 407 is for surrounding the side of the body 404. The bottom 408 has a first opening 409 in the middle and a second opening 410 that is eccentrically located. The first opening 409 is used for being sleeved with the support plate 419. The diameter of the protrusion 420 of the supporting plate 419 is slightly smaller than that of the first opening 409, so that the first opening 409 is in sleeve fit with the protrusion 420, and the positioning of the whole feeding box 402 is also facilitated. In addition, the first opening 409 is provided with a sidewall extending in the opening direction, and the sidewall extends toward the body direction, i.e., toward the inner side of the lower cover 406. Thereby allowing the sidewalls and body 404 to be cooperatively positioned. The second opening 410 is also adapted to receive a support plate 419. The second opening 410 is adapted to mate with an opening 411 in a support plate 419. The second opening 410 is likewise provided with a side wall extending in the opening direction, the side wall of the second opening 410 extending towards the support disc 419, i.e. towards the outside of the lower cover. The opening 411 of the supporting plate 419 is aligned with the blanking opening 312 of the lid 303, so as to ensure that the opening 411 and the blanking opening 312 are always through. Thus, in conjunction with the relationship of the second opening 410 and the opening 411, the second opening 410 in the lower cover 406 is always aligned with the drop opening 312 in the lid when the lower cover 406 is mounted to the support cover 419.

As shown in fig. 10, the upper cover 405 mainly includes a rounded top. The top of the upper cover 405 has an area equivalent to the area of the bottom 408 of the lower cover 406. The top of the upper cover 405 is provided with a feed inlet 412. Seasoning may be added to the seasoning cavity 403 of the body 404 from the port 412. A cover 413 for opening and closing the feed opening 412 is further provided on the feed opening 412. When the charging is needed, the cover 413 can be operated to open so as to expose the charging opening; and when no charging is required, the cover 413 may be operated to close the charging port 412. In the present embodiment, the cover 413 is slidably operated along the surface of the upper cover 405. The upper cover 405 is provided with a sliding groove 414 on the surface, and the cover 413 has a guide rail capable of moving along the sliding groove 414. Of course, in other embodiments, the cover 413 may be operated in other manners, such as a button type, a touch type, and the like. In addition, in order to achieve better assembling effect with the lower cover 406, the side of the upper cover 405 also has a step structure matched with the side wall of the lower cover 406.

The upper cover 405 and the lower cover 406 are both fixedly and detachably mounted, and the body 404 between the upper cover 405 and the lower cover 406 is rotatably mounted. The body 404 is a substantially cylindrical body and is magnetically attached to the accommodating space formed in the cover. The body 404 has a seasoning chamber 403, and external seasoning can be added into the seasoning chamber 403 through the inlet 412 for temporary storage. And the seasoning in the seasoning cavity 403 is poured into the pan 302 again at a subsequent appropriate time. Since a plurality of seasonings are required for cooking one dish and the seasonings required for each dish are different, a plurality of seasoning cavities 403 are often provided in the body 404. And the plurality of seasoning cavities 403 are independent of each other, each seasoning cavity 403 can be filled with a seasoning, so that different seasonings can be stored without tainting each other. Alternatively, several condiments may be placed in each condiment chamber 403, which do not interfere with each other. And the form of the seasoning may be solid or liquid. In this embodiment, the number of seasoning cavities 403 is 5, considering the type of seasoning and the seasoning holding volume that are generally required for one dish. In other embodiments, the number of seasoning cavities 403 may be other numbers such as 7, 6, 4, 3, etc. The seasoning cavity 403 is in the form of a through hole, both ends of which are open, and the middle part of which is through. The seasoning cavity 403 extends in a longitudinal direction. In this embodiment, the body 404 further includes a sealed cavity 415, and the sealed cavity 415 is juxtaposed parallel to the seasoning cavity 403. The sealed chamber 415 is similar to the seasoning chamber 403 and extends in a longitudinal direction, except that the sealed chamber 415 is closed at both ends. In this embodiment, the number of the sealed chambers 415 is 1. Of course, the number of the sealed cavities can be other numbers such as 2, 3, 4 and the like. The seasoning cavity 403 and the sealed cavity 415 are arranged around the center line of the body 404. In this embodiment, the total number of seasoning cavities 403 and sealed cavities 415 is 6, with the 6 cavities evenly distributed along the ring. The angle between two adjacent cavities is thus about 60 degrees. Of course, the included angle varies accordingly with the total number of cavities, generally between 30 and 120 degrees. As shown in FIG. 12, the seasoning chamber 403 has a generally fan-shaped cross-section with a width that narrows radially inward. The short side 426 in the cross-section is closer to the center and the long side 427 in the cross-section is closer to the edge. In addition, chamfer structures 428 are also provided at the corners of the cross-section. The cross-sectional area of the seal chamber 415 in the longitudinal direction is the same size as the seasoning chamber 403.

As shown in fig. 13, the body 404 also has a recess 417. A recess 417 is located at a central position of the body 404, the rotational axis of the body 404 passing through the recess 417. The specific structure of the recess 417 is a blind hole in the body. The opening of the blind hole faces the lower cover 406. A blind hole is located in the center of the body 404 and functions to shape match the protrusion 520 of the support disk 519. When cartridge 402 is mounted to support plate 519, projection 520 of support plate 519 extends through first opening 409 in the center of lower cover 406 and then mates with the blind hole in body 404. There is a transmission hole 418 at the bottom of the blind hole, i.e. the top of the body 404, and the transmission hole 418 is used for connecting with the second motor 425 to realize power transmission, so that the second motor 425 drives the body 404 to rotate. In this embodiment, the drive aperture 418 has internal teeth 419 that mesh with the drive gear of the second motor 425.

As shown in fig. 2, the drive mechanism 420 that drives the body 404 to rotate is received within the recess 417 of the body 404 such that the flavoring chamber 403 of the body 404 is at the same level as the drive mechanism 420. In other words, the height of the flavoring chamber 403 is substantially the same as the height of the drive mechanism 420. Wherein the drive mechanism 420 is centrally located and the seasoning cavities 403 are arranged in a circular pattern around the outside of the drive mechanism 420. The center line of the driving mechanism 420 is arranged to coincide with the center line of the recess 417 and also coincide with the center line of the lid 303. The drive hole 418 at the bottom of the recess 417 engages with a gear of the drive mechanism 420 such that the second motor 425 directly rotates the body 404. And this manner of gear engagement facilitates quick assembly and disassembly of the body 404 and the drive mechanism 420. In this embodiment, since the protrusion 520 of the support plate 519 fits into the recess 417 of the socket body 404, the drive mechanism 420 is also accommodated within the inner space of the protrusion 520. The inner space of the protrusion 520 is slightly larger than the volume of the driving mechanism 420 and is slightly smaller than the inner space of the recess 417 of the body 404, so that the three are connected in a nested manner. Meanwhile, the protrusion 520 may also serve as a cover to protect the driving mechanism 420. Of course, in order to ensure smooth transmission, the transmission gear of the driving mechanism 420 is protruded out of the end of the protrusion 520. In this embodiment, the second motor 425 is a stepping motor, which can precisely control the rotation angle of the body 404 within a cycle. And the utility model discloses well step motor is along a direction for example clockwise rotation all the time, plays the mesh of simplifying control.

The body 404 is rotated about its central axis by a drive mechanism 420. Therefore, the body 404 can rotate relative to the cover to have a plurality of rotational positions. In one of the rotated positions, the seasoning cavities 403 of the body and the second opening 4 of the lower cap 406 are aligned to form the outlet 401 in an open state. And because the blanking port 312 of the pot cover 303 and the second opening 410 of the lower cover 406 are always communicated, the seasoning in the seasoning cavity 403 enters the pot 302 through the discharge port 401 and the blanking port 312, and the position is the blanking position. Of course, since the body has a plurality of seasoning cavities 403, each seasoning cavity 403 corresponds to a blanking position, the seasoning cavity 403 and the lower cover 406 form the discharge port 401 in an open state, and the lower ends of the other seasoning cavities are closed by the lower cover 406. That is, each time the pan is rotated to a blanking position, only one seasoning chamber 403 is opened and only one seasoning is added to the pan 402. For example, when 3 seasonings are to be added to the pot during cooking, the main body 404 of the feeding box needs to be turned to 3 blanking positions, so that the corresponding 3 seasoning cavities 403 are opened sequentially, and the 3 seasonings in the 3 seasoning cavities 403 are added to the pot 302. One revolution of the pod body 404 may cause the pod 402 to switch between multiple outfeed positions.

In addition, due to the requirement of actually using the kitchen robot, the feeding box body 404 is additionally provided with a sealing cavity 415. When the body 404 is in a rotating position, the sealed cavity 415 of the body 404 is aligned with the second opening 410 of the lower cover 406, so as to form the outlet 401 in a closed state, and all the seasoning cavities 403 are closed by the lower cover 406, which is the sealed position. Of course the number of sealing positions and the number of sealing cavities 415 are also equal. In this embodiment, the number of the sealing cavities 415 is 1, and the number of the sealing positions is only 1. A plurality of blanking positions and sealing positions occur in sequence during a cycle of one revolution of the body 404 about the axis.

And the mating of the fill port 412 on the upper cap 405 to the flavoring chamber 403 of the body 404 and the mating of the second opening 410 on the lower cap 406 to the flavoring chamber 403 are similar. The upper cover 405 is disposed near an opening of the upper end of the seasoning chamber 403. When the body 404 is rotated to a position, defined as the loading position, in which the seasoning chamber 403 of the body 404 is aligned with the loading port 412, seasoning can be loaded into the seasoning chamber 403 from the loading port 412. In the loading position, there is one of the brew chambers 403 of the body 404 aligned with the loading port 412 to facilitate loading. If a plurality of seasonings are required, the rotating body 404 can be controlled to rotate to each feeding position, one seasoning can be added into the seasoning cavity 403 aligned with the feeding port 412, and then the rotating body is controlled to rotate to the next feeding position, and another seasoning cavity 403 is aligned with the feeding port to add another seasoning. Therefore, for the seasoning cavity 403, seasoning is added from the upper end of the body 404, and when discharging is needed, the seasoning falls into the pot from the lower end of the body 404.

It is also worth noting that the seasoning cavity 403 also needs to be considered hermetic to prevent seasoning from leaking out of the end. The end of the brew chamber 403 is therefore provided with a seal 421, the seal 421 being able to abut against the inside surface of the lid to form a seal. Specifically, the sealing member 421 is made of a material different from the seasoning chamber, and is formed of silicon rubber, thereby having high flexibility. At the same time, it is also considered that the material of the sealing member must have a certain food safety and must not contaminate the food. Of course, in other embodiments, the sealing member 421 can be made of other materials with certain flexibility. And a sealing member is provided at both upper and lower ends of each seasoning chamber 403. The sealing member at the lower end of the seasoning chamber 403 abuts against the inner side surface of the lower cap, and the sealing member 403 at the upper end of the seasoning chamber 403 abuts against the inner side surface of the upper cap. The seal 421 has a hollow annular configuration that matches the contour of the end of the flavoring chamber 403. Further, the ring-shaped structures on the seal 421 are also disposed at the ends of the seal cavities 403, such that the number of ring-shaped structures on the seal 421 matches the number of seasoning cavities 403 and seal cavities 415. In addition, a connection is provided between the annular structures of the sealing member 421.

In addition to taking into account the sealing action between the brew chamber 403 and the lid at rest, it is also desirable to take into account that the friction between the brew chamber 403 and the lid as they move relative to each other is as low as possible. The inner surface of the cover is thus made of another material, so that the coefficient of friction between this material and the material of the seal is less than 0.8. Preferably, the coefficient of friction is less than 0.5. Such material is therefore a highly lubricious material 422. In this embodiment, this material is polytetrafluoroethylene, i.e., teflon. The material is sprayed on the inner side surface of the cover body. In the scene of practical use, when flavouring chamber and lid are static relatively, flexible silica gel butt is at the surface of polytetrafluoroethylene to form better sealed effect. When flavouring chamber and lid relative rotation, flexible silica gel produces slight deformation, and under actuating mechanism's drive power effect, silica gel slides on polytetrafluoroethylene's surface, can not produce great frictional force to reduce the moment of torsion demand that actuating mechanism needs to provide. In another embodiment, the material of the inner surface of the cover body can also be glass, and the silica gel slides on the surface of the glass. And also does not generate large friction force.

In the direction extending along the center line, the upper cover 405, the lower cover 406, and the body 404 are magnetically attracted to each other for easy quick attachment and detachment. In this embodiment, the body is provided with a first magnetic material 423, and the upper cover and the lower cover are respectively provided with a second magnetic material 424. The first magnetic material 423 and the second magnetic material 424 generate magnetic attraction within a certain distance of the two. Therefore, the upper cover 405 and the body 404 are attracted to each other, and the lower cover 406 and the body 404 are also attracted to each other. The first magnetic material 423 is a magnet, and the second magnetic material 424 is an iron sheet or other metal material. Of course, in other embodiments, the first magnetic material 423 may be a piece of iron or other metal material, and the second magnetic material 424 may be a magnet. In yet another embodiment, the body 404 may be provided without the magnetic material, with the first magnetic material 423 being provided on the upper cover 405 and the second magnetic material 424 being provided on the lower cover 406. The first magnetic material 423 and the second magnetic material 424 are magnetically attracted to each other, so that the body 404 between the upper cover 405 and the lower cover 406 is clamped and positioned. Of course, in another embodiment, the upper cover 405 and the lower cover 406 are not made of metal material such as iron sheet, but are provided with corresponding quick-release structures to facilitate quick disassembly and assembly between the upper cover 405 and the lower cover 405. The quick-release structures can be matched with a buckle and a clamping groove and can also be matched with a protrusion and a sliding groove. The weight of such upper and lower covers 405 and 406 can be further reduced compared to the provision of a metal material.

For better cooking, the kitchen robot 1 of the present invention further has a slice assembly 320. The slice assembly 320 may be disposed within the pan 302 and perform a stir-fry or the like function on dishes while cooking the dishes. The utility model discloses a thereby kitchen robot 1 can control slice subassembly 320 and turn over the stir-fry automatically, has saved user's time and energy. Therefore, the kitchen robot 1 of the present invention includes a driving assembly 321 for driving the rotation of the slice assembly 320. For safety and space saving reasons, the drive assembly 321 of the present invention is disposed outside the pan 302, and the slice assembly 320 is disposed inside the pan 302. As shown in fig. 2, the driving assembly 321 is disposed above the lid 303, and the slice assembly 320 is disposed below the lid 303. The spatula assembly 320 is detachably connected with the driving assembly 321 in a plugging manner, so that quick replacement, cleaning and maintenance are facilitated. The driving assembly 321 has an output shaft 322, and the spatula assembly 320 has a sleeve 323 connected to the output shaft 322, the output shaft 322 can be sleeved in the sleeve 323 to form power transmission. The magnet 324 is provided at the bottom of the sleeve 323 and the output shaft 322 has a magnetic material, so that the output shaft 322 can be quickly inserted into the sleeve 323 and positioned. In addition, the side surfaces of the sleeve 323 and the output shaft 322 have a fool-proof design, which prevents the sleeve 323 and the output shaft 322 from rotating relatively when transmitting power. In the present embodiment, the output shaft 322 has a regular hexagonal shape, and the sleeve 323 has a shape matching the regular hexagonal shape. The drive assembly 321 includes a motor 325, an output shaft 322, and a belt 326 connecting the output shaft 322 and the motor 325. The motor 325 is also provided in the rotating arm 502. The utility model discloses in, because reinforced unit 4 sets up in the top of pot cover 303, the motor 325 of drive assembly 321 consequently eccentric settings leaves the design space for reinforced unit 4. And an output shaft 322 of the driving assembly 321 is disposed along a center line of the pot lid 303, and the motor 325 is connected to the output shaft 322 by a belt 319. The motor 325 via the belt 319 can rotate the output shaft 322 around the center line of the output shaft 322. The motor 325 is preferably a dc brush motor, providing a stable and reliable output with less loss. Further, to control the rotational speed of the output shaft 322 within a desired range, the drive assembly 321 may also include a reduction gearbox.

As shown in fig. 15 and 16, the slice assembly 320 also includes a bracket 326. The sleeve 323 is fixedly disposed on the bracket 326. The output shaft 322 may thus drive the carrier 326 to rotate about the centerline of the output shaft 322, i.e., the first axis 327. The first axis 327 is coincident with the centerline of the lid 303. In the present invention, the bracket 326 has a horizontal bottom 328 and vertical sides 329. The bottom 328 and the side 329 form a receiving space for supporting and receiving the first gear block 331 and the second gear block 332 engaged with each other. The bottom 328 and side 329 are preferably integrally formed. In addition, the bracket 326 has a cover plate 330, and the cover plate 330 covers over the bottom 328. The cover 330 can improve the sealing performance of the accommodating space, and prevent the first gear block 331 and the second gear block 332 in the accommodating space from receiving other liquid gas such as water gas in the pan 302. The projected cross-section of the cover plate 330 and the projected cross-section of the base 328 are substantially the same. In addition, the cover plate 330 is designed to be detachable from the bottom 328, and the sealing silica gel is arranged on the periphery of the cover plate 330, so that the sealing requirement and the rapid detaching requirement are met.

The first gear block 331 is fixedly disposed. The first gear block 331 is provided with a rotation stop structure 334. In fig. 16 and 5, the rotation stop feature 334 is an internal tooth on the first gear piece 331. And the first snap-in portion 510 of the rotating arm 502 is provided with external teeth 522 matching the internal teeth. When the first gear block 331 is installed in place, the inner teeth and the outer teeth 522 are engaged with each other to limit the position. Since the first engaging portion 510 is fixed to the rotating arm 502, the first gear block 331 is also fixed to rotate by the cooperation of the inner and outer teeth. Of course, in other embodiments, other rotation-stopping structures may be adopted as long as the first gear block 331 can be fixed. In addition, in the present invention, the first gear block 331 is sleeved outside the sleeve 323, and a sleeve 335 is further provided inside the first gear block 331. The sleeve 335 allows the sleeve 323 and the sleeve 335 to rotate relatively, i.e. when the sleeve 323 is driven by the output shaft 322 to rotate, the sleeve 335 does not rotate correspondingly, and the first gear block 331 is in a relatively fixed position. Of course, in other embodiments, the first gear block 331 may be mounted at other positions of the bracket as long as the first gear block 331 is fixed.

The second gear block 332 is movably disposed. Since the second gear block 332 is always engaged with the first gear block 332, the second gear block 332 can rotate around the circumference of the first gear block 331. In order to control a proper rotation speed ratio, the number of teeth of the second gear block 332 is smaller than that of the first gear block 331. The radius of the second gear piece 332 is also smaller than the radius of the first gear piece 331. The center line of the second gear block 332 is eccentrically disposed with respect to the rotation center of the output shaft 322.

The slice assembly 320 also has a working head for contacting and processing dishes. In the present invention, the working head of the slice assembly includes a stirring portion 340. The stirring part 340 is used for stirring the dishes and even stir-frying the dishes. In the embodiment shown in fig. 18, the stirring section 340 has the stirring arm 341, and the stirring arm 341 is shaped like an arc as viewed in the rotational movement direction of the stirring arm 341, and the arc of the inner side is bent to a greater extent than the arc of the edge. Therefore, as shown in fig. 18, the entire stirring section 340 has a substantially S-shaped curved surface shape when viewed from above. The stirring arm 341 has a slope 342 at its end. And the other end of the agitating arm 341 is connected to the rotation shaft 343 of the agitating arm 341. The stirring arm 341 is axially rotated about the rotation shaft 343 by the rotation shaft 343. In the present embodiment, the number of the inclined surfaces 342 is 2, and is centrosymmetric with respect to the rotation axis 343.

The stirring section 340 is made of different materials. Specifically, the stirring section main body 344 is made of a hard material, and the stirring section edge 345 is made of a soft material. Thus, the portion of the stirring part contacting the dish is mainly the soft material. The soft material is arranged to contact with the dishes, so that the damage to the soft dishes can be reduced during stirring, and the appearance of the dishes is guaranteed. The utility model discloses in, soft materials is silica gel, installs the edge at stirring portion through the technology of moulding plastics. The material has the advantages that the gap between the stirring part 340 and the inner wall of the pot 302 can be fully filled, and the phenomena of blocking or excessive resistance cannot occur. The stirring section main body 344 is made of a metal material, and is preferably made of aluminum or an aluminum alloy. The metal material is also provided with a coating, and the coating is preferably made of Teflon material.

The rotation shaft 343 of the stirring part 340 is connected to the center of the second gear block 332. As shown in fig. 15, the rotating shaft 343 is fixedly mounted on the second gear block 332 via screws, so that the second gear block 332 drives the stirring part 340 to rotate synchronously. The center line of the second gear block 332 is defined as a second axis 337, and thus the stirring part 340 is rotatable about the second axis 337. The second axis 337 is disposed parallel to the first axis 327 with a spacing therebetween. Alternatively, the second axis 337 is eccentrically disposed relative to the first axis 327. It is noted that the location where the first gear block 331 and the second gear block 332 mesh is between the first axis 327 and the second axis 337. When the second gear block 332 rotates around the first gear block 331, the stirring portion 340 is driven to rotate around the second axis 337. The bracket 326 of the slice assembly 320 simultaneously rotates about the first axis 327 and thus the stirring portion 340 simultaneously rotates about the first axis 327 and the second axis 337. Thus, the stirring area in the pot can be increased without increasing the number of the stirring parts 340. If the element between the stirring part 340 and the driving assembly is defined as a driving assembly, the driving assembly has two driving paths. In the first transmission path, the output shaft 322 directly drives the bracket 326 to rotate around the first axis 327, and therefore the stirring portion 340 correspondingly rotates around the first axis 327. In the second transmission path, the output shaft 322 drives the bracket 326 and simultaneously drives the second gear block 332 to rotate around the first gear block 331, and the second gear block 332 drives the stirring portion 340 to rotate around the second axis 337. As shown in FIG. 15, the height L1 of the stirring section 340 from the top to the bottom is in the range of 25mm to 35mm for good stirring effect. While the total length L2 of stirring section 340 is preferably the radius of pan 302, and does not exceed the diameter of pan 302 at the longest. And the distance L3 between the top of the stirring part 340 and the pot cover 303 is 45 mm-65 mm.

In another embodiment, the working head of the slice assembly 320 may further comprise a scraping portion 350. The function of the vegetable scraping part 350 is mainly to scrape off the vegetables stuck on the inner wall of the pot. In the present embodiment, the vegetable scraping portion 350 is also driven by the driving assembly 321 to rotate. Specifically, the scraping portion 350 is driven to rotate about a first axis 327. The scraping portion 350 is fixedly coupled to the bracket 326 such that the scraping portion 350 rotates with the bracket 326. As shown in fig. 15 to 17, the scraping part 350 and the stirring part 340 are respectively located at both sides of the bracket 326, that is, in the middle of the sleeve 323 through which the rotation center line passes, and the scraping part 350 and the stirring part 340 are respectively located at both sides of the sleeve 323. And the distance from the vegetable scraping part 350 to the sleeve 323 is greater than the distance from the stirring part 340 to the sleeve 323. The scraping part 350 is farther from the sleeve 323, and the stirring part 340 is closer to the sleeve 323. Alternatively, the horizontal distance from the distal end of the scraping portion 350 to the first axis 327 is greater than the horizontal distance from the distal end of the stirring portion 340 to the first axis 327.

The scraping portion 350 has a scraping arm 351 extending in a radial direction of the pot. The vegetable scraping arm 351 is horizontally connected with the bracket 326, so that the height from the vegetable scraping part 350 to the bottom of the pot is greater than that from the stirring part 340 to the bottom of the pot. That is, the stirring part 340 is closer to the bottom of the pot than the dish scraping part 350. In a similar manner to the stirring section 340, the main body 352 of the vegetable scraping section is made of a hard material, while the edge 353 of the vegetable scraping section adjacent to the inner wall of the pan is made of a flexible material.

The scraping portion 350 has various configurations. In the embodiment shown in fig. 16, the scraping portion 350 has a transverse scraping edge 354 and a vertical scraping edge 355 cooperatively formed. The transverse vegetable scraping edge 354 and the vertical vegetable scraping edge 355 form a T shape. And one end of the vegetable scraping arm 351 is connected with the vertical vegetable scraping edge 355. In another embodiment as shown in fig. 20, the scraping portion 350 also has a transverse scraping edge 354 and a vertical scraping edge 355. The transverse vegetable scraping edge 354 and the vertical vegetable scraping edge 355 form an L shape, and one end of the vegetable scraping arm 351 is connected with the transverse vegetable scraping edge 354. And the vertical scraping edge 355 extends downwardly relative to the transverse scraping edge 354. The connection of the transverse vegetable scraping edge 354 and the vertical vegetable scraping edge 355 is provided with an arc-shaped guide structure 356, so that a better vegetable scraping effect is achieved. In another embodiment as shown in fig. 21, the transverse scraping edge 354 and the vertical scraping edge 355 are formed into an inverted U-shaped configuration, one end of the scraping arm 351 is connected with the transverse scraping edge 354, and the two vertical scraping edges 355 are respectively connected with two ends of the transverse scraping edge 354. The vertical vegetable scraping edge 355 extends downward. Preferably, the vertical vegetable scraping edges 355 have a curved arc shape, and the curved directions of the two vertical vegetable scraping edges 355 are opposite to each other.

In one embodiment as shown in fig. 19, one end of the stirring portion 340 of the slice assembly 320 is horizontally disposed, and an inclined surface 346 is disposed at an end surface of the stirring portion 340. The inclined surface 346 extends outward from the horizontal agitating arm 341 and gradually decreases in height. In this embodiment, the stirring section 340 rotates only about the first axis 327. The number of the inclined surfaces 346 may be 1 or 2. If 2, 2 inclined surfaces 346 extend from the stirring arm 341 to both sides, respectively. The width of the inclined surface 346 coincides with the length of the stirring arm 341 horizontal at the end portion. Of course, in this embodiment, the slice assembly 320 may also include a scraping portion 350. The scraping portion 350 also rotates about the first axis 327. The scraping part 350 extends radially outward from the rotation shaft 343, and an included angle between the scraping part 350 and the stirring part 340 is 180 degrees. Of course, in other embodiments, the slice assembly 320 may not include the scraping portion 350.

In another embodiment of the present invention, the present invention relates to a method for controlling a slice assembly. As shown in fig. 22, the control method includes: controlling the rotation of the slice assembly, and controlling the rotation speed of the slice assembly to be V1 in starting time; controlling the rotational speed of the slice assembly at V2 during normal rotation, wherein V2 is less than V1; when the rotation angle of the slice assembly reaches W1, controlling the slice assembly to stop rotating; the above steps are repeated. In the initial step, a relatively fast speed is achieved in a short time as the slice assembly is moved from rest to start-up. The drive assembly thus drives the slice assembly to rotate at a speed of V1. Wherein the starting time is preferably 0.5-1.5 seconds. And at speed V2, the slice assembly has reached a state of normal operation, at which point the drive assembly drives the slice assembly to rotate at a speed of V2, where V2 is less than V1. That is, the shovel assembly rotates at a slower speed during normal operation. This is because the spatula assembly can cause damage to the dishes if the speed is too high. In a subsequent step, the slice assembly has rotated a certain angle at the speed of V2 and the drive assembly drives the slice assembly to pause for a period of time. The rotation angle in the step S3 is preferably less than 90 degrees, and the pause time is preferably 2-5 seconds. The previous process is then repeated. The arrangement enables the turner component to intermittently rotate, and the stirring effect on dishes is very ideal. It is noted that in embodiments where there is only one ramp, the direction of rotation of the slice assembly of the above method is one, i.e., in line with the direction of inclination of the ramp. In the embodiment with 2 ramps, the rotation direction of the slice assembly may be forward rotation for one period of time and reverse rotation for another period of time. In addition, in the above method, the rotation period is from the start to the pause, and the rotation angle or the pause time is adjustable in different periods.

The usage scenario of the present embodiment is described herein. The scene is suitable for the stir-frying stage of dishes. At the beginning of this phase, the slice assembly needs to be changed from a resting state to an activated state, so the drive assembly controls the slice assembly to reach a high rotational speed in a short time. Then, the turner assembly enters a normal working state after a period of time, the rotating speed of the turner assembly is slowed down, and a low rotating speed state is achieved, so that a better stir-frying effect can be realized. When the turner assembly rotates a certain angle, the turner assembly stops rotating, so that the possibility of vegetable accumulation in the pan can be reduced. As the stir-frying action of people, the stir-frying is carried out slowly and quickly, and the stir-frying is stopped after a period of time, so that the inner part of the dish can be fully and uniformly cooked.

In addition, the utility model aims at the possible locked-rotor condition of the turner component in the stir-frying process. To address this situation, an embodiment of the present invention discloses a control method. As shown in fig. 23, the control method includes: the turner assembly is controlled to rotate at a certain speed. In this state, the slice assembly operates in a normal state. And detecting the current of a motor for controlling the rotation of the slice assembly, and if the current increase does not exceed a set value, keeping the current unchanged. Whether the locked rotor condition is met or not is identified by detecting the current value of the motor. If the current change does not exceed the preset value, the motor is in a normal working state, and the rotating speed of the turner assembly is kept unchanged. I.e. remain in the original operating state. If the detected current increases beyond a set value, the motor is controlled to rotate in the opposite direction. And if the current is increased to exceed the set value, indicating the locked rotor condition of the motor. In this case, the motor is controlled to rotate in the reverse direction. The voltage of the motor is increased and the motor is controlled to rotate in the positive direction. When the motor rotates reversely for a certain angle, the voltage of the motor is adjusted and increased, the output torque is increased, and then the motor rotates forwards. And continuously detecting the current of the motor. If the detected current decreases beyond a set value, the voltage of the motor is controlled to decrease, so that the slice assembly continues to rotate at a certain speed. In the process, if the current is reduced and exceeds a set value, the problem of locked rotor is solved, and the normal working current is returned. At this time, the voltage of the motor is controlled to drop back to the original normal state. In this process, if the detected current decrease does not exceed the set value, the motor is controlled to rotate in the opposite direction. If the current is not reduced obviously or the current does not exceed the set value, the locked rotor problem still exists, and the motor is controlled to rotate reversely. The locked-rotor condition is solved by using reverse impact force. It is noted that in normal operation, the slice assembly rotates at a certain speed. The speed is generally 30 to 50 rpm. This is the normal rotational speed of the slice assembly. After the motor rotates reversely for a certain angle, the voltage of the motor is preferably raised to the maximum voltage, so that more torque is provided. This maximum voltage is typically 12V. After the voltage of the motor is reduced, the rotational speed of the slice assembly preferably coincides with the rotational speed of the slice assembly during normal operation. While still stalling, the voltage controlling the reverse rotation of the motor is preferably still maintained at the maximum voltage.

In another embodiment, as shown in fig. 24, the previous steps of the control method are the same as those in the previous embodiment, except for one of the steps. In this embodiment, in this step, the motor is controlled to stop rather than to rotate in the reverse direction. In an alternative, in addition to controlling the motor to stop, an alarm signal may be issued during this step. The alarm signal may be in the form of a sound, light, etc.

In addition, in order to ensure that the blanking which can be smoothly carried out cannot be influenced by the slice assembly 320, the sensor 360 is further arranged on the slice assembly, the receiver 361 is fixedly arranged on the kitchen robot, and when the feeding unit 4 rotates to the discharging position in response to a sensing signal received by the receiver 361, the projections of the slice assembly 320 and the blanking port 312 in the vertical direction are not overlapped. This is because it is desirable that the slice assembly 320 not obscure the blanking opening 312 when the loading unit 4 is ready to be blanked into the pan 302. Seasoning that falls from the drop opening 312 is likely to fall onto the slice assembly 320 rather than directly into the pan 302, thereby detracting from the user experience. Thus, the receiver 361 and sensor 360 are provided to ensure that the spatula assembly 320 in the pan does not interfere with the blanking prior to the blanking of the feeding unit 4. In this embodiment, the slice assembly 320 is fixedly provided with a sensor 360, and as the slice assembly rotates, the sensor 360 correspondingly rotates. And a receiver 361 for receiving a sensing signal from the sensor 360 is provided on the first catching portion 510 of the rotating arm 502. The advantage of this arrangement is that the signal can be received more accurately, on the one hand, in a relatively fixed position and, on the other hand, close to the centre line of rotation. Since the lid 303 is fixedly connected to the first engaging portion 510, the sensor 360 can also be fixedly disposed on the lid 303. The sensor 360 may be a proximity sensor, i.e., the receiver is able to receive signals from the sensor when the sensor is in a position close to the receiver, and the receiver is unable to receive signals from the sensor when the sensor is in a position away from the receiver. Specifically, the sensor 360 of the present invention may be a magnet, and the receiver 361 may be a magnetic switch, which may correspondingly emit a high level signal or a low level signal. Based on the position of the sensor 360 relative to the drop opening 312, and in combination with the received sensor signal, the position of the spatula assembly 320 relative to the drop opening 312 can be identified.

In one embodiment, the receptacle 361 is positioned away from the drop opening 312. The center of rotation of the slice assembly 320 is located between the drop opening 312 and the receptacle 361. Preferably, the angle formed by the drop opening 312 and the receptacle 361 relative to the center of rotation of the slice assembly 320 is in the range of 90-270 degrees. Most preferably, the included angle is 180 degrees. Thus, rotation of the sensor 360 on the slice assembly 320 to a position proximate the receiver indicates that the slice assembly 320 is not blocking the drop opening 312. At this time, the blanking can be controlled. The utility model discloses in, kitchen robot still includes little the control unit MCU, little the control unit MCU with received signal and send control command. The micro control unit MCU controls the charging unit 4 to rotate to the discharging position when receiving the signal from the receiver 312. When the sensor 360 on the slice assembly 320 is rotated to a position away from the receiver 361, it is indicated that the slice assembly 320 may block the drop opening 312. At this time, the blanking is controlled to stop. Specifically, the micro control unit MCU controls the charging unit 4 to stop rotating when it does not receive the signal from the receiver.

When the magnet is far away from the magnetic control switch, the magnetic control switch controls to output a high level signal; when the magnet approaches the magnetic control switch, the magnetic control switch controls and outputs a low level signal. When the MCU detects a low level signal and lasts for a certain time, the feeding unit 4 is controlled to rotate to a discharging position, and seasonings in the feeding unit 4 can enter the pot from the discharging port. Preferably, the duration is 0 to 30 milliseconds.

In another embodiment, the receptacle 361 may be mounted to the drop opening 312. Similar to the control logic of the previous embodiment, the MCU, upon receiving the signal from the receiver 361, indicates that the spatula assembly 320 will block the blanking to the blanking opening 312, thereby controlling the feeding unit 4 to stop rotating.

The utility model discloses a kitchen robot's use scene is introduced below.

Scene one

When a user needs to cook dishes and put in the main materials, or the main materials are put in according to the program instruction, the user inputs an instruction from the outside or the instruction set in the program starts the first motor, and the first motor drives the pot cover to open through the rotating arm. When the first motor is turned on, the first motor stops working, and the pot cover stays at a preset position. At this time, the main materials can be conveniently added into the pot. And after the main materials are added, externally inputting an instruction again or starting the first motor to drive the pot cover to be closed by an internal instruction of the program. After a short period of time, the pot cover is completely covered on the pot, and the first motor stops working. When auxiliary materials such as seasonings and the like need to be added subsequently, the pot cover does not need to be opened again due to the existence of the feeding unit. Only when the last dish is cooked and needs to be taken out of the pot, the pot cover needs to be controlled to be opened. That is to say, the whole cooking process only needs the process of opening the pot cover twice, so that the trouble that the pot cover needs to be opened frequently in the previous cooking process is solved, and the operation burden of a user is reduced.

Scene two

When a user needs to add auxiliary materials, since a plurality of auxiliary materials, such as edible oil, salt, shallot, vinegar, soy sauce, etc., are required for cooking each dish in the past and the adding time of each auxiliary material is different, it takes time and labor for the user to manually add the auxiliary materials. And because the utility model discloses a kitchen robot has automatic control's reinforced unit, the user that can significantly reduce cooks the energy that the vegetable consumes, promotes the enjoyment of culinary art and the quality of life. When in the stage of adding the auxiliary materials, the seasoning box rotates to sequentially form a plurality of charging positions. The user can put the auxiliary materials required by the current dish into the seasoning cavity in sequence, so that the addition of all the auxiliary materials required by the dish is completed at one time. The user can then even leave the kitchen robot to go elsewhere, avoiding the user being bound in the kitchen. The feeding unit of the kitchen robot can be controlled according to a program, a seasoning box of the feeding unit rotates to a discharging position in a preset proper time period, and auxiliary materials in the seasoning cavity enter the pot through the discharging hole.

Scene three

When the turner component is used for stir-frying dishes in the pan, a good stir-frying effect is realized. The slice assembly is rotated at a high speed when activated and at a low speed when operating normally. The low-speed stirring helps to protect the dishes from being easily damaged. After the slice assembly rotates for a certain time at a low speed, or after the slice assembly is converted to rotate for a certain angle, dishes are easy to roll together after being stirred, so that the slice assembly is controlled to suspend rotation, the dishes are dispersed by the aid of the gravity of the slice assembly without external stirring interference, and then the dishes are stirred at the low speed again. The mode of stir-frying dishes is more consistent with the stir-frying style of the chef.

Scene four

In addition, some dishes are easy to be wound on the slice assembly along with the deep stir-frying degree, so that the load of the slice assembly is increased, and the motor for driving the slice assembly is blocked. For detecting the current of the motor, if the current is increased greatly, the locked rotor condition is met. The turner assembly is controlled to rotate reversely, so that a certain stroke is formed between the turner assembly and the position where the rotation blockage occurs. The locked rotor problem can then be solved by controlling the boost motor voltage, preferably to a maximum voltage, so that the motor has a large output torque, and then rotating it in the forward direction to impact the location just locked rotor. And then, continuously detecting the current condition of the motor, and if the current returns to the normal state, indicating that the locked rotor problem is solved. If the current value is still larger, the problem of locked rotor is not solved. An alternative plan is also prepared for this purpose, which consists of controlling the voltage of the hoisting motor, preferably to a maximum voltage, in order to raise the output torque of the motor, as before. And then controlling the motor to rotate reversely, so that the reverse rotation of the motor impacts the position just locked.

Scene five

When the feeding unit feeds seasoning into the pan through the blanking port, there may be a situation where the spatula assembly passes right under the blanking port, so that the seasoning falls onto the spatula assembly rather than into the pan. For this purpose, sensors and receivers are provided on the slice assembly and the pan cover or the swivel arm. The position of the slice assembly is then sensed based on the signals from the sensors. When the turner assembly is far away from the blanking port, the feeding unit is controlled to feed seasonings from the blanking port. Thereby avoiding the trouble that the blanking falls on the slice assembly.
