For the self-cleaning food processor of this embodiment, there is an automatic pulping process (as shown in fig. 8) as follows:

the treatment stage comprises the following steps: the liquid discharge valve assembly is in a closed state, water is fed into the pulping chamber, and the materials in the pulping chamber are soaked or cleaned for a preset time period.

Separation: the valve core is controlled to rotate to a second position, the liquid discharge inlet is communicated with the liquid outlet, the waste water treated in the pulping chamber is discharged to the waste water cup through the liquid discharge valve assembly, and the materials are reserved in the pulping chamber.

And (3) cleaning: and controlling the drain valve assembly to return to a closed state, feeding water into the pulping chamber, and cleaning the pulping chamber.

Waste discharge stage: the control valve core rotates to a first position, the liquid discharge inlet is completely communicated with the liquid outlet, and the cleaning wastewater in the pulping cavity is discharged to the wastewater cup through the liquid discharge valve assembly.

The automatic cleaning food processor of the embodiment adopts the method, can realize the operations of automatic cleaning or soaking, automatic waste water discharge, automatic pulping and automatic cleaning of materials, and has stronger functions and higher degree of automation compared with the food processor without washing by hands in the prior art.

Meanwhile, for the food processor of the embodiment, the drain valve assembly is communicated with and disconnected from the pulping chamber by controlling the valve core to rotate. When the valve core is positioned at the first position, the valve core completely communicates the liquid discharge inlet with the liquid outlet, so that the slurry in the pulping chamber or the waste water after the pulping chamber is cleaned can be discharged through the liquid discharge valve assembly; when the valve core moves to the third position, the liquid discharge inlet is in a cut-off state relative to the liquid outlet, and the food processor can perform operations of automatic water inlet, automatic pulping and automatic cleaning. When the valve core moves to the second position, the valve core can be communicated with the same liquid outlet inlet and the liquid outlet, compared with the complete communication state of the liquid outlet inlet and the liquid outlet, the partial communication can reduce the opening degree of the liquid outlet, large materials can be limited in the pulping chamber by the liquid outlet assembly and cannot be discharged, and waste water for cleaning materials or soaking materials can be discharged through the liquid outlet valve assembly. Compared with the existing self-cleaning food processor, the food processor of the embodiment has the automatic cleaning function for materials and the reservation function for automatically soaking the materials, so that the functional attribute of the food processor is greatly expanded, more requirements of consumers are met, and the food processor of the embodiment is higher in automation degree.

In addition, compared with the existing food processor with filter meshes, the food processor is smoother in material-water separation, the problem that impurities or slurry residues block the meshes is avoided, and the drain valve assembly can be automatically cleaned and is easier to maintain. In addition, even if small materials enter the liquid discharge channel in the process of separating the materials from the water, the small materials cannot be blocked in the liquid discharge channel due to the small opening of the liquid discharge inlet, and the small materials can still be automatically discharged through the liquid discharge channel. Even if small materials are adhered to the inner wall of the liquid discharge channel, when the food processor enters the waste discharge stage, the cleaning water can flush the small materials out of the liquid discharge channel, so that the problem of blocking the liquid discharge channel is avoided.

It should be noted that, in the stage of separating the material from the water in the food processor of this embodiment, when the material is stuck at the liquid outlet, the material may be extruded back into the pulping chamber by driving the valve core to reciprocate by a small margin. Of course, when the food processor of this embodiment is processing the material, not only soak or reserve the soak to the material, can also carry out slow stirring to the material in the in-process of soaking to under the prerequisite of not broken material, the soaking of accelerating the material, further reduction purine substance in the material. In addition, the food processor of the embodiment can also be used for cleaning materials so as to remove dust and impurities on the surfaces of the materials.

The food processor of the embodiment can realize the filtering and separating operation of the materials and the water when the valve core is positioned at the second position. Therefore, the problems of preventing materials from entering the liquid discharge channel through the liquid discharge inlet to cause the blockage of the liquid discharge channel and ensuring the efficiency of wastewater separation are all the difficulties of the utility model. The inventor finds through research that when the liquid discharge inlet is partially communicated with the liquid outlet, if the liquid discharge inlet is opened more, the material is relatively easier to fall into the liquid discharge channel, and if the liquid discharge inlet is opened less, the waste water after washing or soaking flows out more slowly due to the viscosity of water, and even if the filtering and separating time is prolonged, more waste water remains in the pulping chamber, and the separating efficiency is relatively lower. The present inventors found through studies that, for the food of this exampleFor the processing machine, when the valve core is positioned at the second position, the area S2 of the drain inlet which is partially opened relative to the liquid outlet is related to the area S1 of the drain inlet which is fully opened relative to the liquid outlet when the valve core is positioned at the first position, and when the S2/S1 is not more than 1/2, the food processing machine of the embodiment can realize cleaning and soaking of soybeans; however, when S2/S1 is less than 1/10, the separation efficiency is low, and the waste water is liable to be discharged cleanly. For the present embodiment, S2 is generally selected to be 30mm ² ～100mm ² . Wherein s2=35 mm ² ～90mm ² When the beans are soaked and cleaned, more than 90% of beans of different varieties can be soaked and cleaned. In addition, in this embodiment, when the valve core is located at the second position, the liquid discharge inlet and the liquid outlet are communicated to form a strip-shaped communication hole, and the inventor finds that the horizontal width of the liquid discharge inlet opened relative to the liquid outlet is generally selected to be 2 mm-10 mm, so that soybean can be ensured not to fall into the liquid discharge channel. The horizontal width of the partial opening is preferably 3mm to 5mm in order to prevent clogging of the drain passage, based on the fact that the user may add rice or the like during soaking or washing.

In this embodiment, only one drain inlet is provided on the outer side wall of the valve element for communication with the drain passage. When the valve core is positioned at the first position and the second position, the liquid draining inlet communicated with the liquid outlet is the same inlet. Of course, for the present embodiment, the outer side wall of the valve core may be further provided with a connection port circumferentially spaced with respect to the drain inlet, the connection port may be in communication with the drain passage, and external cleaning water in communication with the connection port may directly flush the drain passage.

The structure of the drain valve assembly of the present utility model is not limited to the structure disclosed in this embodiment. Also, for example: the drain valve assembly comprises a valve shell, the valve core is arranged in the valve shell and moves in a translation mode, the drain inlet is arranged on the valve shell, the drain inlet and the liquid outlet are opposite to each other, the drain channel is arranged in the valve shell, and the valve core is arranged in the valve shell and moves in a translation mode, so that the drain inlet is opened and closed. Or, be provided with the intercommunication mouth just right with the liquid outlet on the valve casing, the flowing back passageway sets up in the case, and the flowing back entry sets up on the lateral wall of case, the case is located the translation in the valve casing to make flowing back entry and intercommunication mouth intercommunication and shutoff. That is, the drain valve assembly of the present utility model is applicable to a valve housing having a translational movement of the valve element, and can achieve three different positions of the valve element. Also, in the above configuration, the first detection element, the second detection element, and the third detection element may be disposed on the same straight line.

Of course, for the liquid discharging nozzle of the present embodiment, the movement between the pulp discharging position and the waste discharging position is not limited to the rotation disclosed in the present embodiment, and the liquid discharging nozzle can also be driven by the driving device to linearly translate between the pulp discharging position and the waste discharging position to realize the switching. Even the liquid discharging nozzle of the embodiment can be inactive, and a user can manually switch the slurry receiving cup and the waste water cup when discharging slurry and waste water. In order to facilitate cleaning of the tapping spout, it is also possible for the present embodiment to provide the tapping spout to be detachable with respect to the valve housing.
