Wherein, the food processor can be machines on the market, such as a soybean milk machine, a food processor, a wall breaking machine, a juice extractor, a blender, a coffee machine and the like.

Referring to fig. 9, in an embodiment of the method for controlling a food processing machine according to the present invention, the method for controlling a food processing machine includes the steps of:

step S10, when receiving a control command, controlling the driving device to drive the squeezing mechanism so as to switch the slurry discharge valve between a conducting state and a closed state;

step S20, acquiring stroke control parameters of the extrusion mechanism, wherein the stroke control parameters comprise the movement duration of the extrusion mechanism and/or the current position of the extrusion mechanism;

and step S30, controlling the driving device to stop driving the extrusion mechanism to move when the control parameter meets the preset condition.

In this embodiment, the food processor may receive control instructions. Wherein the control command comprises a slurry discharge command or a slurry discharge valve closing command. When a slurry discharge instruction is received, the extrusion mechanism is driven to move by controlling the driving device, so that the slurry discharge valve enters a conducting state. So that slurry in the food processor can flow out of the slurry discharge valve. When a closing instruction of the slurry discharge valve is received, the driving device is controlled to drive the extrusion mechanism to move, so that the slurry discharge valve enters a closed state, and slurry in the food processor cannot flow out of the slurry discharge valve.

Specifically, when the control instruction is received, the driving device can be controlled to drive the pressing mechanism to move beyond the first direction or move towards the second direction. And when receiving a closing instruction of the slurry discharge valve, controlling the driving device to drive the extrusion mechanism to move towards a second direction so as to switch the slurry discharge valve to a closed state.

In the process of driving the extrusion mechanism to move, the slurry discharge valve can also acquire stroke control parameters of the extrusion mechanism, wherein the stroke control parameters comprise the movement duration of the extrusion mechanism and/or the current position of the extrusion mechanism. And controlling the driving device to stop driving the extrusion mechanism to move when the control parameter meets the preset condition. Optionally, the preset condition includes: the movement time of the extrusion mechanism is longer than or equal to a preset time, and/or the current position of the extrusion mechanism is in a preset closing position or a preset conducting position.

In order that those skilled in the art may better understand the scope of the claims of the present invention, the present invention is further explained below by some specific examples.

Example 1, in an embodiment, a food processor is provided with a position detection sensor. The position detection creator user obtains a current position of the squeezing mechanism. When a pulp discharge instruction is received, the current position of the extrusion mechanism is detected, and then when the current position of the extrusion mechanism does not reach the conduction position, the food processor can control the extrusion mechanism to move towards the first direction, and when the current position reaches the conduction position, the pulp discharge valve is judged to be completely opened, so that the extrusion mechanism is controlled to stop moving. Or when a closing instruction of the slurry discharging valve is received, the current position of the extruding mechanism is obtained in real time, when the extruding mechanism does not reach the preset closing position, the extruding mechanism is controlled to move towards the second direction, and when the current position of the extruding mechanism reaches the preset closing position, the extruding mechanism is controlled to stop moving.

Example 2, in one embodiment, the slurry discharge valve is in a conducting state when the squeezing mechanism reaches a maximum angle. When the extrusion mechanism is at the minimum angle, the slurry discharge valve is in a closed state. The relationship between the angle value of the pressing mechanism and the movement time length T when the pressing mechanism moves towards the first direction is shown in fig. 10, and the relationship between the angle value of the pressing mechanism and the movement time length T when the pressing mechanism moves towards the second direction is shown in fig. 11. In fig. 10, the movement time T of the pressing mechanism is positively correlated with the angle value. It can be understood that, according to different movement modes of the driving mechanism and the squeezing mechanism, the movement time T of the squeezing mechanism may be in a linear relationship or a nonlinear relationship with the angle value. Similarly, the relationship between the movement time T of the pressing mechanism and the angle value shown in fig. 11 may be a linear relationship or a non-linear relationship. Further, based on the relationship between the movement time length T of the squeezing mechanism and the angle value given in fig. 10 and 11, it may be determined that the angle value corresponding to the squeezing mechanism is the maximum angle when the movement time length of the squeezing mechanism moving to the first direction is greater than or equal to the first time length, that is, the slurry discharge valve is already in the fully-opened state. Or the movement time of the extrusion mechanism moving to the second direction is longer than or equal to the second time, the angle value corresponding to the extrusion mechanism is judged to be the minimum angle, namely the slurry discharge valve is in a completely closed state. Therefore, the preset condition may be set such that the movement time period of the pressing mechanism to move in the first direction is greater than or equal to the first time period; or the movement time of the pressing mechanism moving to the second direction is longer than or equal to the second time.

It should be noted that, in example 2, the first time period and the second time period may be equal or may not be equal. Wherein the first and second durations are generally set to be greater than or equal to 0.5 s. For example, it may be set to any one of [1s,10s ]. In a preferred embodiment, the first and second durations are set to be within the [1s,6s ] interval.

Example 3, based on example 2 above, with reference to fig. 12, after the step of controlling the driving device to stop driving the pressing mechanism to move, the method further includes:

step S40, when the extrusion mechanism is stopped to be driven to move towards the first direction, the driving device is controlled to drive the extrusion device to keep a third time length at the current position; or when the extrusion mechanism stops driving to move towards the second direction, controlling the driving device to drive the extrusion device to keep the extrusion device at the current position for a fourth time.

In example 3, in order to ensure that the inertia of the movement of the mechanism is released when the pressing mechanism is stopped from being driven in the first direction or the second direction, the driving device may be controlled to drive the pressing device at the current position (the position at which the movement in the first direction is stopped, i.e., the stop position) for a third period of time when the pressing mechanism is stopped from being driven in the first direction, or the driving device may be controlled to drive the pressing device at the current position (the position at which the movement in the second direction is stopped, i.e., the stop position) for a fourth period of time when the pressing mechanism is stopped from being driven in the second direction.

It should be noted that, in example 3, the third time period and the fourth time period may be set to be equal or may be set to be unequal. Wherein the third duration and the fourth duration are both greater than or equal to 0.1 s. For example, the third time period and the fourth time period may be set within an interval of [0.5s,10s ]. In a preferred embodiment, the third time period and the fourth time period are set within the interval [1s,6s ].

Example 4, based on the above example 1, and any one of the examples 2 and 3, the food processor may be provided with two mechanisms of detecting a movement duration and a position, that is, when the pressing mechanism moves in the first direction, and when it is detected that the movement duration is greater than or equal to the first duration and the current position is at the on position, it is determined that the control parameter satisfies a preset condition, and the driving device is controlled to stop driving the pressing mechanism to move. Or when the extrusion mechanism moves towards the second direction, when the movement duration is detected to be greater than or equal to the second duration and the current position is in the closed position, the control parameter is judged to meet the preset condition, and the driving device is controlled to stop driving the extrusion mechanism to move.

It should be noted that fig. 9 is not intended to limit the execution sequence of step S10 and step S20, that is, when a control command is received, the stroke control parameter of the extrusion mechanism is acquired, and the driving device is controlled to drive the extrusion mechanism, so that the steps can be executed simultaneously, or when a control command is received, the stroke control parameter of the extrusion mechanism is acquired first, and then the driving device is controlled to drive the extrusion mechanism.

In this embodiment, when receiving control command, control the drive arrangement drive extrusion mechanism, so that arrange thick liquid valve and switch between on-state and closed state, and then acquire extrusion mechanism's stroke control parameter when the control parameter satisfies preset condition, control drive arrangement stop drive extrusion mechanism motion is owing to can judge control through control parameter drive arrangement stop drive the opportunity of extrusion mechanism motion to make the stroke control of arranging thick liquid valve more accurate, avoided manual control to arrange thick liquid valve stroke, lead to arranging the motion stroke that thick liquid valve machine expanded not in place, arrange thick liquid valve appearance weeping or arrange the not smooth phenomenon of thick liquid and take place, reached when promoting food processing's use convenience, improve the effect of arranging thick liquid valve's performance.

Referring to fig. 13, based on the foregoing embodiment, in another embodiment, before the step S10, the method further includes:

step S50, receiving the control instruction issued by the user; or triggering the slurry discharge valve to close when the food processor is detected to be powered on, a feeding command is received and/or the food processor is in a food processing state.

In this embodiment, the food processor may be provided with a user interface. Wherein, the user interface can be arranged as a case or a touch screen or a remote control device, etc. In some embodiments, the user interface may also be a food processor, wherein the food processor may be communicatively coupled to the food processor via a local area network or the internet, such that the food processor may interact with a user using the food processor as the user interface.

As an alternative, the user may send control commands to the food processor via a user interface. When the food processor receives the control command, steps S10-S30 may be performed.

As a further embodiment, the food processor may trigger the control command autonomously. For example, when the food processor is set to be in a power-off state and the slurry discharge valve is in a conducting or semi-conducting state, in order to avoid the phenomenon that the material to be processed flows out of the slurry discharge port due to the fact that the material to be processed is added without issuing a slurry discharge valve closing instruction after power-on work is performed by a user, the slurry discharge valve closing instruction can be automatically triggered after the machine is powered on. Optionally, in order to avoid outflow of the material to be processed, the discharge valve closing command may also be triggered autonomously when a feeding command is received and/or the food processor is in a food processing state.

Optionally, in this embodiment, in order to avoid frequent triggering of the slurry discharge valve closing instruction by the food processor, before the self-discharging triggering of the slurry discharge valve closing instruction, the state of the slurry discharge valve may be detected, and if the state is a closed state, the slurry discharge valve closing instruction is not triggered, otherwise, the slurry discharge valve closing instruction is triggered autonomously.

In the technical solution disclosed in this embodiment, the control instruction issued by the user is received; or triggering the slurry discharge valve to close when the food processor is detected to be powered on, a feeding command is received and/or the food processor is in a food processing state. Therefore, the operation steps of a user can be reduced, and the use convenience of the food processor is improved.
