For the soymilk machine, a soymilk receiving container and a waste water box are arranged outside the whole machine so as to be used for receiving the soymilk liquid discharged by the liquid discharge pipe or the cleaning water discharged by the liquid discharge pipe.

In the above patent, the outlet end of the liquid discharge pipe is connected to the liquid discharge pipe, and then rotated to the pulp discharge position to discharge pulp or to the waste water discharge position to discharge waste water. Therefore, it may be caused that the drain pipe has started to drain slurry when the drain pipe has not been rotated to the slurry draining position, or that the drain pipe has started to drain washing water when the drain pipe has not been rotated to the waste water draining position. The slurry beverage or the cleaning water discharged in this way is easy to spill outside the slurry receiving cup or the waste water box, not only causes beverage waste, pollutes the table top and the ground, but also easily scalds consumers when serious, and has potential safety hazards.

The discharge valve 8 comprises a valve core with a communication hole 80, and the valve core is driven by the second driving means 52, the communication hole 80 being used for the valve core to communicate the pulp container with the discharge pipe 2 during rotation.
In this embodiment, the liquid discharge valve is a planar rotary valve, the valve core is a planar movable valve block 81, and the liquid discharge valve 8 further includes an upper static valve block 82 and a lower static valve block 83, and the upper static valve block and the lower static valve block are respectively provided with a static valve hole 84 opposite to the upper static valve block, the rear end of the liquid discharge pipe 2 is communicated with the static valve hole 84 on the lower static valve block 83, the static valve hole 84 on the upper static valve block 82 is communicated with the pulping container, the planar movable valve block 81 is installed between the upper static valve block 82 and the lower static valve block 83, and is positioned on the same rotating shaft with the upper static valve block 82 and the lower static valve block 83, the planar movable valve block 81 rotates relative to the upper static valve block and the lower static valve block, when the planar movable valve block 81 rotates to enable the communicating hole 80 to gradually overlap with the static valve holes 84 on the upper static valve block and the lower static valve block, the pulping container is communicated with the liquid discharge pipe 2, and the liquid discharge pipe 2 can perform liquid discharge operation.
Meanwhile, the drain valve assembly of the present embodiment further includes a mounting housing 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 housing 5, the front end of the drain pipe 2 is located outside the mounting housing 5, and the drain pipe 2 can rotate relative to the mounting housing 5. Meanwhile, the installation shell 5 is fixed at the bottom of the pulping container, wherein sealing treatment is needed between the upper static valve plate 82, the lower static valve plate 83 and the installation shell 5, and between the installation shell 5 and the pulping container, and between the lower static valve plate 83 and the liquid discharge pipe 2, so as 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 communication holes 80 of the plane moving valve plate 81 are two, including a slurry discharge hole 801 and a wastewater discharge hole 802 that are spaced apart from each other, and the liquid discharge pipe 2 is alternatively connected to the slurry discharge hole 801 or the wastewater discharge hole 802 in the rotation process of the plane moving valve plate 81. Meanwhile, in the present embodiment, the teeth of the first incomplete gear and the teeth of the second incomplete gear are staggered up and down and do not overlap (as shown in fig. 3), so that the first incomplete gear and the second incomplete gear do not drive the driven component 7 and the planar moving valve plate 81 to work at the same time.
In this embodiment, the first incomplete gear drives the intermediate gear first, and after the driven gear drives the liquid discharge tube to rotate to a predetermined position, the first incomplete gear is separated from the intermediate gear and is not driven any more, and the liquid discharge tube stops rotating correspondingly, at this time, the second incomplete gear starts to mesh with the plane moving valve plate and drives the plane moving valve plate to rotate, and when the slurry discharge hole or the wastewater discharge hole on the plane moving valve plate coincides with the static valve holes on the upper static valve plate and the lower static valve plate, the slurry making container is communicated with the liquid discharge tube. Thereby, the liquid discharge valve communicates the pulping container with the liquid discharge pipe after the liquid discharge pipe rotates to a preset position. Therefore, the problem that the liquid discharge pipe discharges slurry or waste water in the rotating process can be avoided, and the use safety and reliability of the food processor are greatly improved.
For a better understanding of the inventive concepts of the present utility model, the operation of the drain valve assembly when draining slurry and waste water from a food processor will be described herein:
and (3) a pulp discharging process: when the pulping container is manufactured and the pulp needs to be discharged, the motor drives the first incomplete gear and the second incomplete gear to rotate simultaneously due to the fact that the first incomplete gear and the second incomplete gear are of an integrated structure, meanwhile, gear teeth on the first incomplete gear and the second incomplete gear are staggered and do not overlap in the axial direction, the first incomplete gear is meshed with the driven component first and drives the liquid discharge pipe to rotate, in the process of rotating the liquid discharge pipe, the second incomplete gear is not meshed with the plane movable valve plate, therefore, the plane movable valve plate still keeps a non-rotating state, after the liquid discharge pipe rotates to a first 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 be meshed with the plane movable valve plate, and drives the plane movable valve plate to rotate, and when a pulp discharge hole on the plane movable valve plate rotates to the plane movable valve plate is gradually overlapped with 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 discharging operation on the pulp in the pulping container.
Valve closing process: when the pulp discharge is completed, the motor drives the second incomplete gear to reversely drive the plane movable valve plate to rotate, so that the pulp discharge hole and the static valve hole are closed, the pulp making container and the liquid discharge pipe are closed, and according to program setting, the motor stops working at the moment, and the food processor can automatically perform water feeding and cleaning operations on the pulp making container.
Waste discharge process: when the pulping container is cleaned, the motor is started again according to the program setting, the motor drives the plane movable valve plate to rotate continuously and reversely until the second incomplete gear is disengaged from the plane movable valve plate, meanwhile, the first incomplete gear is just engaged with the driven component and drives the liquid discharge pipe to reversely rotate, when the liquid discharge pipe rotates to a second preset position above the wastewater box, 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 is just rotated to be engaged with the plane movable valve plate again and drives the plane movable valve plate to continuously rotate, when the wastewater discharge holes on the plane movable valve plate rotate to be 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 discharges the cleaning water in the pulping container.
The concept of the present embodiment is that the liquid discharge pipe and the liquid discharge valve do not work simultaneously, and the liquid discharge valve is driven by the second driving device until the pulping container is communicated with the liquid discharge pipe after the liquid discharge pipe rotates to the corresponding preset position (the first preset position or the second preset position). The principle of implementing this idea in this embodiment mainly consists in: the first driving device drives the driven component to drive the liquid discharge pipe to rotate, and 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, wherein the first driving device, the driven component and the second driving device form two groups of intermittent transmission mechanisms with the movable valve plate. The two groups of intermittent transmission mechanisms effectively avoid the problem that the liquid discharge pipe does not rotate in place and the valve is opened to discharge liquid.
For this embodiment, the second driving device may also drive the liquid discharge valve for multiple times during the pulp discharging process or the waste discharging process, so that the pulp container and the liquid discharge pipe are communicated and closed multiple times, thereby realizing multiple liquid discharge of the liquid discharge pipe, and the liquid discharge pipe is always kept at the corresponding predetermined position during the liquid discharge process. For the food processor of this embodiment, if pulp is discharged for multiple times in the pulp discharging process, and when the liquid discharge valve is turned off each time, the water tank or the water inlet device can firstly feed water into the pulping container for blending, then the stirring device in the pulping container is used for stirring and mixing the pulp uniformly, and then pulp is discharged, so that the food processor can produce multiple people's pulp drinks when the food processor has a small-capacity pulping container. And if the waste discharge is carried out for a plurality of times in the waste discharge process, and when the liquid discharge valve is turned off each time, the cleaning water in the pulping container is whipped through the whipping device and then discharged, the food processor can be automatically cleaned more cleanly, or when the liquid discharge valve is turned off each time, the water is fed into the pulping container through the water feeding device so as to wash the inner wall of the pulping container, and then the waste is discharged, so that the food processor can be automatically cleaned more cleanly.
It should be noted that, in this embodiment, the driven assembly may not need an intermediate gear, but only the driven gear is configured to directly drive the driven gear to rotate the liquid discharge tube by the first driving device. Meanwhile, in the embodiment, the driven gear and the liquid discharge pipe can be integrally formed, and can be integrally connected in a split installation and fixation mode.
Of course, in this embodiment, the first driving device and the second driving device may be driven by different motors, and the first motor is controlled by a program to drive the first driving device to drive the liquid discharge tube to rotate to a predetermined position and then stop rotating, and then the second motor drives the second driving device to drive the plane moving valve plate to rotate until the pulping container is communicated with the liquid discharge tube. However, the driving mode has higher driving cost compared with the same motor, and the whole machine needs larger installation space during installation. Meanwhile, in order to improve the reliability of the rotation 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 not, or detect whether the plane movable valve plate rotates to be communicated with the pulping container and the liquid discharge pipe or not, and when the communication is detected, the motor is controlled to stop working, so that the plane movable valve plate stops rotating, and the purpose of continuous liquid discharge of the liquid discharge pipe is achieved.
In addition, in order to prevent the liquid discharge tube from manually rotating, a rotation stopping rib can be further arranged on the driven component, for example, in the embodiment, the first incomplete gear is provided with a first driving tooth and an arc portion vertically staggered with the first driving tooth, the middle gear is provided with the rotation stopping rib, and the rotation stopping rib is provided with an arc surface corresponding to the outline of the arc portion, so that when the arc surface is matched with the side surface of the arc portion, the arc portion can move along the surface of the arc surface along with the rotation of the first incomplete gear driven by the motor. Thereby effecting a first partial gear intermittent drive driven assembly. However, because the rotation stopping rib and the circular arc part form a rotation stopping structure, if an external force is applied to rotate the liquid discharge pipe, the driven component still cannot actively rotate, so that the phenomenon that the liquid discharge pipe rotates by mistake in the liquid discharge process is effectively avoided, and the risk of scalding consumers is avoided. Of course, in this embodiment, there may be a plurality of arc portions and first driving teeth on the first incomplete gear, and when there are a plurality of arc portions and first driving teeth, the arc portions and the first driving teeth need to be arranged at intervals, and adjacent arc portions and first driving teeth need to be in a staggered state. Of course, in the present embodiment, the upper and lower end surfaces of the first incomplete gear may be provided with arc portions, and in this case, the upper and lower end surfaces of the intermediate gear also need to be provided with two rotation stopping ribs opposing the arc portions. The setting can strengthen driven gear's locking intensity, prevents to lead to the fact the cracked problem of anti-rotating rib because of external force is too big. Moreover, the inventor finds through research that the arc length of the single arc part is generally not less than 8mm, because if the arc length of the single arc part is too small and less than 8mm later, the rotation stop rib can still bypass the arc part by actively applying external force to the liquid discharge pipe, so that the phenomenon that the driven component can still rotate occurs. In view of this, in the structure of this embodiment, the arc length of the arc portion and the stopper rib is generally required to be not less than 8mm. In addition, in this embodiment, since the liquid discharge pipe has two liquid discharge states, a slurry discharge state and a waste water discharge state, two symmetrical rotation stopping ribs need to be disposed on the intermediate gear, so as to realize the rotation stopping with different rotation stopping ribs when liquid is discharged at different positions.
It should be noted that the above-described structural changes for the present embodiment may also be applied to other embodiments of the present utility model.
Embodiment two:
referring to fig. 7 and 8, a schematic diagram of a second embodiment of a drain valve assembly for a food processor according to the present utility model is shown. In this embodiment, the first driving device 51 and the second driving device 52 are also driven to operate by the same motor 50. The first difference between this embodiment and the second embodiment is that: the first driving device 51 is a first incomplete gear, the second driving device 52 is a second complete gear, the plane moving valve plate 81 is driven by the second complete gear, only one communication hole 80 is formed in the plane moving valve plate 81, and the liquid discharge pipe 2 is connected with the communication hole 80, wherein the first incomplete gear drives the driven component, the second complete gear synchronously drives the plane moving valve plate 81 to work, and when the first incomplete gear rotates to be separated from the driven component, the second complete gear continuously drives the plane moving valve plate 81 to rotate to the communication hole 80 to be communicated with the liquid discharge pipe 2.
For a better understanding of the inventive concepts of the present utility model, the operation of the drain valve assembly when draining slurry and waste water from a food processor will be described herein:
and (3) a pulp discharging process: as shown in fig. 9, before the slurry is discharged, when the slurry is required to be discharged from the slurry container, the first incomplete gear and the second complete gear are also in an integrated structure, the motor drives the first incomplete gear and the second complete gear to rotate simultaneously in the 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 moving valve plate and drives the plane moving valve plate to rotate, when the first incomplete gear drives the driven component to drive the slurry discharge pipe to rotate to a first preset position above the slurry receiving cup (the position shown by the dotted line in fig. 9 is the position of the slurry discharge pipe), because the first incomplete gear and the driven component are in intermittent transmission, after the slurry discharge pipe rotates to the first preset position, the first incomplete gear is just disengaged from the driven component, the slurry discharge pipe does not rotate any more, the second complete gear is still drives the plane moving valve plate to rotate, when the communication hole on the plane moving valve plate rotates to the upper static valve plate and the lower static valve plate is gradually overlapped with the slurry container, and the slurry is communicated with the slurry discharge pipe to perform slurry discharge operation in the slurry container.
Valve closing process: as shown in fig. 10, after the pulp discharge is completed, the second complete gear drives the plane moving valve plate to rotate anticlockwise, so that the communication hole and the static valve hole are closed, and the pulp container and the liquid discharge pipe are closed. Meanwhile, the second complete gear continuously drives the plane movable valve plate to rotate in the reverse direction, and as the first incomplete gear and the second complete gear are of an integrated structure and driven by the same motor, when the second complete gear rotates to the first incomplete gear to be meshed with the driven component again, the first incomplete gear can reversely drive the driven component to rotate, and when the driven component drives the liquid discharge pipe to rotate to a second preset position above the waste water box, the first incomplete gear is just disengaged from the driven component. According to the program setting, when the liquid discharge pipe rotates to a second preset position above the waste water box and keeps still (the position shown by the dotted line in fig. 10 is the waste discharge position of the liquid discharge 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 be close to 3/4 circles, the pulping container and the liquid discharge pipe are still in a cut-off state, the control device controls the motor to stop working, and at the moment, the food processor starts to automatically perform water feeding and cleaning operations on the pulping container.
Waste discharge process: as shown in fig. 11, after the pulping container is cleaned, according to the program setting, the motor is started again and drives the first incomplete gear and the second complete gear to continue rotating in the anticlockwise direction, at this time, the first incomplete gear and the driven component are still in a disengaged state, the liquid discharge pipe is still at a second preset position above the waste water box (the position shown by the dotted line in fig. 11 is the waste water discharge position above the waste water box), the second complete gear can continue driving the plane movable valve plate to rotate, and when the communication hole on the plane movable valve plate is gradually communicated with the static valve hole, the pulping container is communicated with the liquid discharge pipe, and the liquid discharge pipe performs waste water 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 plane moving valve plate rotates to the communication hole and is communicated with the static valve hole, after the detection device detects a signal, the signal is transmitted 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, meanwhile, the detection device can also be used for detecting that the plane moving valve plate rotates to a state that the communication hole and the static valve hole are closed, and when the detection device is in a valve closed state, the control device controls the motor to stop rotating, and the food processor can perform cleaning operation on the pulping container.
It should be noted that the concept of the present embodiment is that the liquid discharge pipe and the liquid discharge valve work simultaneously, and the liquid discharge valve is driven by the second driving device continuously after the liquid discharge pipe rotates to the corresponding predetermined position until the pulping container is communicated with the liquid discharge pipe. The principle of implementing this idea in this embodiment mainly consists in: the first driving device drives the driven component to drive the liquid discharge pipe to rotate, and 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, wherein the first driving device and the driven component 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 liquid discharge pipe does not rotate in place and the valve is opened to discharge liquid.
For the present embodiment, the intermittent transmission of the first driving device and the driven assembly may be a sheave intermittent transmission mechanism in addition to the intermittent transmission of the incomplete gear and 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 of the first driving device and the driven component in this embodiment is not limited to the gear transmission and the sheave transmission of the incomplete gear, but may be other intermittent transmission mechanisms with the same function.
In this embodiment, after the liquid discharge pipe rotates to the corresponding predetermined position, the movement is stopped for t time, and after t time, the liquid in the pulping container begins to be discharged from the liquid discharge pipe, and it is found through researches that t is generally at least 0.2s, so that the liquid discharge pipe can be fully ensured, and the liquid discharge is performed after the liquid discharge pipe rotates in place, so that the use safety and reliability of the food processor are further improved. In this embodiment, when the liquid discharge pipe rotates from the first predetermined position to the second predetermined position, the food processor firstly feeds water into the pulping container, then controls the crushing device to stir the cleaning water in the pulping container so as to clean the pulping container, and after the cleaning is finished, the second driving device drives the liquid discharge valve to work again until the waste water starts to discharge. In this process, the time required for the food processor to clean from the water inlet to the completion of the cleaning is T, and the time required for the drain to start discharging the wastewater from the stop of the rotation is T, and it is apparent that T > T.
The above-described structure and variations of the present embodiment can be applied to other embodiments of the present utility model.
It will be appreciated by persons skilled in the art that the present utility model includes, but is not limited to, the accompanying drawings and what has been described in the foregoing detailed description. Any modifications which do not depart from the functional and structural principles of the present utility model are intended to be included within the scope of the appended claims.
