A kind of food processing machine rotary valve control method

Abstract

An embodiment of the invention discloses a rotary-valve control method of a food processor. A Rotary valve of the food processor comprises an upper rotary valve body and a lower rotary valve body, the upper rotary valve body is in charge of pipeline switching between a cup and a water inlet, a sealing port, a pulp discharge port and an additional port, and the lower rotary valve body is in charge of switching between the pulp discharge port and a wastewater box; the method includes: detecting current states of the food processor, wherein the current states include the standby state and the working state; controlling motion direction and motion range of the rotary valve according to the current location of the rotary valve of the food processor in the standby state and the working state respectively. By the arrangement, the optimum motion path can be automatically judged according to pulping conditions, safe and reliable switching of pipelines is guaranteed, motion time of the rotary valve is shortened, and pulping circle is shortened.

Description

technical field [0001] Embodiments of the present invention relate to cooking device control technology, in particular to a method for controlling a rotary valve of a food processor. Background technique [0002] The current food processors (such as puree machines) have the following problems: [0003] (1) The current puree machine basically can automatically feed water and clean automatically, eliminating the tedious operation of adding water and cleaning by the user, which greatly facilitates the use of the user. In the current technology, the switching of multiple pipelines inside the puree machine is realized through the rotary valve: firstly, the stepping motor is used to drive the rotary valve to rotate, and then the position sensor is used to detect the fixed rotation position, and the rotary valve is controlled to switch to the set position. For pipelines, the control method is relatively simple. When the sensor fails or the detection fails, it cannot be found in ti...

Problems solved by technology

In the current technology, the switching of multiple pipelines inside the puree machine is realized through the rotary valve: firstly, the stepping motor is used to drive the rotary valve to rotate, and then the position sensor is used to detect the fixed rotation position, and the rotary valve is controlled to switch to the set position. Pipeline, the control method is relatively simple, when the sensor failure or detection failure cannot be found in time, it is easy to cause the risk of pipeline leakage or even scald customers

[0004] (2) In the current technology, when the internal rotary valve of the raw pulp machine is switched, the rotation of the rotary valve is simply controlled according to the set program, and the action of the rotary valve cannot be controlled in real time in combination with the actual situation in the pulping process to adapt to the pulping of the raw pulp machine Environmental changes ensure the reliability of the puree machine system, especially in order to better enhance the user experience and realize multi-functions in the current puree machine, some of them have a steam system. When steam is generated or steam is heated, if the valve is turned If the action is not timely or the action is too fast, the steam in the pipeline will not be discharged, forming a large internal pressure of the pipeline, which will reduce the service life of the pipeline in the slightest, and directly burst the pipeline in severe cases, posing a great safety risk

[0005] (3) At present, multiple pipelines in the puree machine system can be connected to each other through the rotary valve. When the rotary valve operates, it will inevitably pass through other pipelines and cause some non-purpose pipelines to be connected for a short time. If the rotary valve operates at an appropriate time and the action direction cannot adapt to the pulping environment of the original pulp machine in real time, which will cause the slurry to overflow or flow through other pipelines, which will not only cause the pipeline to be dirty, but also affect the pulping effect

[0006] (4) At present, the action of the rotary valve inside the raw pulp machine system is generally set in advance, which cannot guarantee the safe and reliable switching of the pipeline, and at the same time, the action of the rotary valve will be in place as soon as possible, shorten the action time of the rotary valve, and reduce the pulping cycle
