referring to fig. 3, 4 and 5, there is shown a schematic structural view of a drain valve assembly of a food processor according to a first embodiment of the present invention.
In this embodiment, the drain valve assembly further includes a driven assembly 7 for driving the drain pipe 2 to rotate, the driven assembly 7 includes an intermediate gear 71 and a driven gear 72, wherein the intermediate gear 71 is driven by the first driving device 51, the driven gear 72 is driven by the intermediate gear 71 to rotate, the drain pipe 2 penetrates through the driven gear 72 and is integrally connected with the driven gear 72, and the drain pipe 2 rotates along with the rotation of the driven gear 72. The drain valve 8 comprises a valve core with a communication hole 80, the valve core is driven by the second driving device 52, and the communication hole 80 is used for communicating the pulping container with the drain pipe 2 during the rotation of the valve core.
In this embodiment, the drain valve is a planar rotary valve, the valve core is a planar movable valve plate 81, the drain valve 8 further includes an upper stationary valve plate 82 and a lower stationary valve plate 83, the upper and lower stationary valve plates are respectively provided with a stationary valve hole 84 facing the upper and lower stationary valve plates, the rear end of the drain pipe 2 is communicated with the stationary valve hole 84 on the lower stationary valve plate 83, the stationary valve hole 84 on the upper stationary valve plate 82 is communicated with the pulping container, the planar movable valve plate 81 is installed between the upper stationary valve plate 82 and the lower stationary valve plate 83, and is positioned on the same rotating shaft as the upper stationary valve plate 82 and the lower stationary valve plate 83, the planar movable valve plate 81 rotates relative to the upper and lower stationary valve plates, when the planar movable valve plate 81 rotates to make the communicating hole 80 coincide with the stationary valve holes 84 on the upper and lower stationary valve plates, the pulping container is communicated with the drain pipe 2, and the drain pipe 2 can perform a drain operation.
Meanwhile, the drain valve assembly of the present embodiment further includes a mounting case 5, the first driving device 51, the second driving device 52, the driven assembly 7, and the drain valve 8 are all mounted in the mounting case 5, the front end of the drain pipe 2 is located outside the mounting case 5, and the drain pipe 2 is rotatable relative to the mounting case 5. Meanwhile, the mounting shell 5 is fixed at the bottom of the pulping container, wherein the upper static valve sheet 82, the lower static valve sheet 83 and the mounting shell 5, the mounting shell 5 and the pulping container, and the lower static valve sheet 83 and the liquid discharge pipe 2 are sealed to prevent leakage in the liquid discharge process.
In this embodiment, the first driving device 51 and the second driving device 52 are integrally formed, and the first driving device 51 and the second driving device 52 are driven by the same motor 50, the first driving device 51 is a first incomplete gear, the second driving device 52 is a second incomplete gear, and the two communicating holes 80 of the planar movable valve plate 81 include a slurry discharge hole 801 and a wastewater discharge hole 802 which are arranged at an interval, and in the rotating process of the planar movable valve plate 81, the drain pipe 2 is selectively connected with the slurry discharge hole 801 or the wastewater discharge hole 802. Meanwhile, in this embodiment, the gear teeth of the first incomplete gear and the second incomplete gear are staggered up and down and are not overlapped (as shown in fig. 3), so that the first incomplete gear and the second incomplete gear do not drive the driven assembly 7 and the flat movable valve plate 81 to work simultaneously.
In this embodiment, the first incomplete gear drives the intermediate gear first, and the driven gear drives the drain pipe to rotate to a predetermined position, the first incomplete gear is disengaged from the intermediate gear and is not driven any more, and the drain pipe also stops rotating correspondingly, at this time, the second incomplete gear starts to be engaged with the planar movable valve plate and drives the planar movable valve plate to rotate, and when the slurry discharge hole or the waste water discharge hole on the planar movable valve plate is overlapped with the static valve holes on the upper and lower static valve plates, the slurry making container is communicated with the drain pipe. Therefore, the pulping container is communicated with the liquid discharge pipe only by the liquid discharge valve after the liquid discharge pipe rotates to a preset position. Therefore, the problem that the discharge pipe discharges pulp or waste water in the rotating process can be avoided, and the use safety and the reliability of the food processor are greatly improved.
For a better understanding of the inventive concept of the present invention, the operation of the drain valve assembly when draining slurry and waste water from a food processor is described herein:
a pulp discharging process: when the pulping container is manufactured with pulp and needs to discharge pulp, because the first incomplete gear and the second incomplete gear are in an integral structure, the motor drives the first incomplete gear and the second incomplete gear to rotate simultaneously, meanwhile, because the gear teeth on the first incomplete gear and the second incomplete gear are axially staggered and not overlapped, the first incomplete gear is firstly meshed with the driven component and drives the liquid discharge pipe to rotate, in the rotating process of the liquid discharge pipe, because the second incomplete gear is not meshed with the plane rotating valve plate, the plane rotating valve plate still keeps a non-rotating state, when the liquid discharge pipe rotates to a preset position above the pulp receiving cup, the first incomplete gear is just disengaged from the driven component, the liquid discharge pipe does not rotate any more, at the moment, the second incomplete gear just rotates to start to be meshed with the plane rotating valve plate and drives the plane rotating valve plate to rotate, when the plane movable valve plate rotates to the position that the slurry discharge hole on the plane movable valve plate is gradually overlapped with the static valve holes on the upper static valve plate and the lower static valve plate, the pulping container is communicated with the liquid discharge pipe, and the liquid discharge pipe performs slurry discharge operation on slurry in the pulping container.
And (3) valve closing process: after the pulp discharging is finished, the motor drives the second incomplete gear to reversely drive the plane movable valve plate to rotate so as to close the pulp discharging hole and the static valve hole, the pulp container and the liquid discharging pipe are shut off, and according to the program setting, the motor stops working at the moment, and the food processing machine can automatically perform water inlet and cleaning operations on the pulp container.
The waste discharge process comprises the following steps: after the pulping container is cleaned, according to the program setting, the motor can be started again, and the second incomplete gear is continuously driven in a reverse direction to drive the plane movable valve plate to rotate until the second incomplete gear is disengaged from the plane movable valve plate, meanwhile, the first incomplete gear is just meshed with the driven component and drives the liquid discharge pipe to rotate reversely, when the liquid discharge pipe rotates to a preset position above the wastewater box, the first incomplete gear just disengages from the driven assembly, the liquid discharge pipe does not rotate any more, at the moment, the second incomplete gear also just rotates to be engaged with the plane movable valve plate again and drives the plane movable valve plate to continue rotating, when the plane movable valve plate rotates to the waste water discharge hole on the plane movable valve plate to be gradually superposed with the static valve holes on the upper static valve plate and the lower static valve plate, the pulping container is communicated with a liquid discharge pipe, and the liquid discharge pipe is used for carrying out waste discharge operation on cleaning water in the pulping container.
It should be noted that, in the present embodiment, the drain pipe and the drain valve do not work simultaneously, and the drain valve starts to be driven by the second driving device to communicate the pulping container with the drain pipe after the drain pipe rotates to a predetermined position. The principle of the present embodiment for realizing this idea mainly lies in: the first driving device drives the driven assembly to drive the liquid discharge pipe to rotate, the second driving device drives the planar movable valve plate to rotate relative to the upper and lower static valve plates, and the first driving device and the driven assembly, and the second driving device and the movable valve plate form two groups of intermittent transmission mechanisms. The two groups of intermittent transmission mechanisms effectively avoid the problems that the drain pipe does not rotate in place and the valve is opened to drain liquid.
It should be noted that, for the embodiment, the driven assembly may not need an intermediate gear, but only has a structure of a driven gear, and the first driving device directly drives the driven gear to drive the liquid discharge pipe to rotate. Meanwhile, in the embodiment, the driven gear and the liquid discharge pipe can be integrally formed, and can also be integrally connected in a separated installation and fixation mode.
In this embodiment, the first driving device and the second driving device may also be driven by different motors, the first motor is controlled by a program to drive the first driving device to drive the liquid discharge pipe to rotate to a predetermined position and then stop rotating, and the second motor drives the second driving device to drive the planar movable valve plate to rotate to communicate the pulping container with the liquid discharge pipe. However, the driving mode has higher driving cost compared with the same motor, and a larger installation space is needed when the whole machine is installed. Meanwhile, in order to improve the rotation reliability of the liquid discharge pipe, a detection device can be arranged in the installation shell to detect whether the liquid discharge pipe rotates in place or whether the plane movable valve plate rotates to communicate the pulping container with the liquid discharge pipe, and when the communication is detected, the plane movable valve plate stops rotating by controlling the motor to stop working, so that the aim of continuous liquid discharge of the liquid discharge pipe is fulfilled.
In addition, in order to prevent the drain pipe from being manually rotated, a rotation stopping rib may be further disposed on the driven assembly, for example, in this embodiment, the first incomplete gear has a first driving tooth and an arc portion vertically staggered with the first driving tooth, and the intermediate gear is provided with the rotation stopping rib. Thereby realizing the first incomplete gear intermittent drive driven assembly. However, the rotation stopping rib and the arc part form a rotation stopping structure, so that the driven assembly still cannot rotate actively when an external force is applied to rotate the liquid discharge pipe, the phenomenon that the liquid discharge pipe rotates by mistake in the liquid discharge process is effectively avoided, and the risk of scalding of a consumer is avoided. Certainly, in this embodiment, there may be a plurality of circular arc portions and a plurality of first driving teeth on the first incomplete gear, and when there are a plurality of circular arc portions and a plurality of first driving teeth, the circular arc portions and the first driving teeth need to be arranged at intervals, and adjacent circular arc portions and the first driving teeth need to be in a staggered state. Of course, in the present embodiment, the arc portions may be provided on both the upper and lower end surfaces of the first incomplete gear, and in this case, two rotation stopping ribs opposite to the arc portions need to be provided on both the upper and lower end surfaces of the intermediate gear. This setting can strengthen driven gear's locking intensity, prevents to cause the cracked problem of stalling muscle because of external force is too big. The inventor of the present invention has found through research that the arc length of the single arc portion is generally not less than 8mm, because if the arc length of the single arc portion is too small and less than 8mm, the rotation stopping rib can still bypass the arc portion by actively applying an external force to the liquid discharge pipe, and thus the driven assembly can still rotate. Accordingly, in the structure of the present embodiment, the arc lengths of the arc portion and the stopper rib are required to be not less than 8 mm. In addition, in this embodiment, because the fluid-discharge tube has two flowing back states, thick liquid state and row's waste water state, consequently, need set up the only muscle that changes of two symmetries on the intermediate gear to when realizing different positions flowing back with the only muscle cooperation of difference stop changes.
It should be noted that the above structural changes for the present embodiment can also be applied to other embodiments of the present invention.
Example two:
referring to fig. 6 and 7, a second embodiment of the drain valve assembly of the food processor is shown. In this embodiment, the first driving device 51 and the second driving device 52 are also driven by the same motor 50. The difference between the present embodiment and the first embodiment is: the first driving device 51 is a first incomplete gear, the second driving device 52 is a second complete gear, the planar movable valve plate 81 is driven by the second complete gear, only one communicating hole 80 is formed in the planar movable valve plate 81, and the liquid discharge pipe 2 is connected with the communicating hole 80.
For a better understanding of the inventive concept of the present invention, the operation of the drain valve assembly when draining slurry and waste water from a food processor is described herein:
a pulp discharging process: as shown in fig. 8, before discharging the slurry, the drain pipe is located at a second predetermined position above the wastewater box, when the slurry in the slurry container needs to be discharged, because the first incomplete gear and the second complete gear are also of an integral structure, the motor drives the first incomplete gear and the second complete gear to simultaneously rotate in a clockwise direction, the first incomplete gear is meshed with the driven component and drives the driven component to rotate, the second complete gear is meshed with the plane movable valve plate and drives the plane movable valve plate to rotate, when the first incomplete gear drives the driven component to drive the drain pipe to rotate to a first predetermined position above the slurry cup (the position indicated by the dotted line in fig. 8 is the position where the drain pipe is located), because the first incomplete gear and the driven component are in intermittent transmission of the incomplete gear, after the drain pipe rotates to the first predetermined position, the first incomplete gear just disengages from the driven component, the liquid discharge pipe does not rotate any more, the second complete gear is a complete gear and still can drive the plane movable valve plate to rotate, when the plane movable valve plate rotates until the communicating hole on the plane movable valve plate is gradually superposed with the static valve holes on the upper static valve plate and the lower static valve plate, the pulping container is communicated with the liquid discharge pipe, and the liquid discharge pipe performs pulp discharge operation on pulp in the pulping container.
And (3) valve closing process: as shown in fig. 9, after the pulp discharging is completed, the second complete gear drives the plane movable valve plate to rotate counterclockwise, so that the communicating hole and the static valve hole are closed, and the pulp making container and the liquid discharge pipe are shut off. Meanwhile, the second complete gear continues to reversely drive the plane movable valve plate to rotate, the first incomplete gear and the second complete gear are of an integral structure and are driven by the same motor, when the second complete gear rotates to mesh the first incomplete gear and the driven assembly again, the first incomplete gear can reversely drive the driven assembly to rotate, and when the driven assembly drives the liquid discharge pipe to rotate to a second preset position above the waste water box, the first incomplete gear just disengages from the driven assembly. According to the program setting, when the drain pipe rotates to a second preset position above the waste water box and keeps still (the position shown by the dotted line in fig. 9 is a waste discharge position of the drain pipe above the waste water box), the second complete gear still drives the plane movable valve plate to rotate until the plane movable valve plate rotates to about 3/4 circles, the pulping container and the drain pipe are still in a shut-off state, the control device controls the motor to stop working, and at the moment, the food processor starts to automatically carry out water inlet and cleaning operations on the pulping container.
The waste discharge process comprises the following steps: as shown in fig. 10, after the pulping container is cleaned, according to the program setting, the motor is restarted and drives the first incomplete gear and the second complete gear to continue rotating in the counterclockwise direction, at this time, the first incomplete gear and the driven component are still in a disengaged state, the drain pipe is still in the second preset position above the waste water box for waste discharge and remains still (the position shown by the dotted line in fig. 10 is the waste discharge position where the drain pipe is above the waste water box), the second complete gear continues to drive the planar movable valve plate to rotate, when the communication hole on the planar movable valve plate is gradually communicated with the static valve hole, the pulping container is communicated with the drain pipe, and the drain pipe performs waste discharge operation on cleaning water in the pulping container.
It should be noted that, in this embodiment, the liquid discharge valve assembly is further provided with a detection device for detecting that the planar moving valve plate rotates to the communication hole and is communicated with the static valve hole, and when the detection device detects a signal, the detection device transmits the signal to the control device to control the motor to stop rotating, so as to realize continuous slurry discharge or waste discharge of the liquid discharge pipe.
It should be noted that, in the present embodiment, the drain pipe and the drain valve work simultaneously, and the drain valve is driven by the second driving device to communicate the pulping container with the drain pipe only after the drain pipe rotates to a predetermined position. The principle of the present embodiment for realizing this idea mainly lies in: the first driving device drives the driven assembly to drive the liquid discharge pipe to rotate, the second driving device drives the plane movable valve plate to rotate relative to the upper static valve plate and the lower static valve plate, the first driving device and the driven assembly are intermittent transmission mechanisms, and the second driving device and the plane movable valve plate are complete gear rotation mechanisms. The former intermittent transmission mechanism can effectively avoid the problem that the valve is opened to drain liquid when the drain pipe does not rotate to the position.
For the embodiment, the intermittent transmission of the first driving device and the driven assembly can be a sheave intermittent transmission mechanism besides the intermittent transmission of the incomplete gear and the gear of the complete gear. For example, the first driving device is a cylindrical pin which rotates periodically, the driven component is a grooved wheel driven by the cylindrical pin, the grooved wheel drives the liquid discharge pipe to rotate, and the cylindrical pin and the grooved wheel form an intermittent transmission grooved wheel mechanism. Of course, the intermittent transmission between the first driving device and the driven assembly in this embodiment is not limited to gear transmission and sheave transmission, but may be other intermittent transmission mechanisms with the same function.
It should be noted that the above-described structure and variations of the present embodiment can also be applied to other embodiments of the present invention.
It will be appreciated by those skilled in the art that the present invention includes, but is not limited to, those illustrated in the accompanying drawings and described in the foregoing detailed description. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
