Since the slurry discharge pipe 51 is in a normally connected state with the communication outlet 522 of the valve element 52, the opening and closing of the slurry discharge rotary valve depends on the position of the communication inlet 521 of the valve element 52, so that the valve element 52 is provided with an induction magnet 58 for detecting the position of the valve element, and the corresponding rotary valve system is provided with a hall detection plate 59 for detecting the position of the valve element in cooperation with the induction magnet. In this embodiment, two induction magnets are disposed on the valve core, wherein one induction magnet is located at the same position as the communication inlet 52, or corresponds to the center of the communication inlet 52, the second induction magnet is located symmetrically to the first induction magnet, and the hall plate may be disposed at the communication inlet or at the corresponding reverse position. Generally, for the convenience of installation, set up the hall plate in the opposite place of the reverse of intercommunication inlet, when the hall plate detected first response magnet, explain the intercommunication inlet is kept away from the row thick liquid hole on the cup, and the commentaries on classics valve is in the closed condition this moment, and when the hall plate detected second response magnet, that just explains that first response magnet has got back to row thick liquid hole position, and the commentaries on classics valve is in the open mode this moment, is used for arranging thick liquid this moment. Meanwhile, the design is convenient for the valve core to have enough time to drive the slurry discharge pipe 51 to the corresponding position. That is, the communication inlet hole is not communicated with the slurry discharge hole when the valve core has enough stroke to ensure that the slurry discharge rotary valve rotates.
Because the function of the pulp discharge rotary valve is to discharge the object of the cup body, no matter prepared food or cleaned wastewater, namely, the pulp discharge pipe is necessarily communicated with the pulp discharge hole, and when the valve core drives the pulp discharge rotary valve to rotate, the pulp discharge pipe is not communicated with the pulp discharge hole, namely, at least when the pulp discharge pipe is communicated with the pulp discharge hole, the pulp discharge pipe is static, namely, after the valve core drives the pulp discharge pipe to rotate to a certain position, the pulp discharge pipe does not rotate any more, and the valve core continues to rotate, so that the communication inlet hole of the valve core is communicated with the pulp discharge hole, and finally the pulp discharge pipe is communicated with the pulp discharge hole so as to discharge the object in the cup body. In this embodiment, the slurry discharge pipe is located at the slurry receiving cup position, i.e. the slurry discharge position, and the slurry discharge pipe is located at the waste water box position, i.e. the waste water position, so that the slurry discharge position and the slurry discharge pipe are the same as each other at the slurry receiving cup position, and the waste water position and the slurry discharge pipe are the same as each other at the waste water box position.
The slurry outlet pipe 51 is connected with the valve core 52 in a matching way, and the slurry outlet pipe 51 can rotate along with the valve core 52 when the communication inlet 521 and the slurry outlet are in a non-conduction state.
Specifically, the slurry discharge pipe 51 is rotatably connected with the valve core 52, the valve core 52 is provided with a clamping groove 523 for clamping the slurry discharge pipe 51, the slurry discharge pipe 51 is provided with a fastening convex point 513 matched with the clamping groove 523, the fastening convex point 513 is clamped on the clamping groove 523, and the valve core 52 drives the slurry discharge pipe 51 to rotate under the action of no other external force. Therefore, the pulp discharging pipe can rotate along with the valve core 52 under the non-conduction state of the pulp discharging hole communicated with the pulp inlet 521, and the pulp discharging pipe is ensured to keep a fixed position when the pulp inlet 521 and the pulp discharging hole are communicated.
The food processor is provided with a pulp discharging position and a waste water discharging position, and the pulp discharging pipe is rotationally switched between the pulp discharging position and the waste water discharging position, so that the corresponding pulp discharging or waste water discharging is realized. Specifically, in this embodiment, as shown in fig. 5 to 8, the stop baffle 502 is disposed on the rotary valve housing 50 and is matched with the stop protrusion 512, and when the stop protrusion 512 moves to the stop baffle 502, the stop baffle prevents the rotary valve housing from moving further, so as to move to a desired pulp discharging position or a desired waste water discharging position. The slurry discharge pipe reciprocates within a limited range between the position of the slurry receiving cup and the position of the wastewater box so as to switch slurry discharge and wastewater discharge.
In this embodiment, the slurry discharge pipe 51 has two stop bumps corresponding to the slurry discharge position and the waste water discharge position of the slurry discharge pipe. Specifically, as shown in fig. 5 and 6, when the valve core 52 rotates and drives the slurry discharge pipe to be in the slurry discharge position, the slurry discharge pipe is kept in the slurry discharge position, that is, the slurry discharge pipe is located at the slurry receiving cup position, because the stop protrusion 512 cooperates with the stop baffle 502 on the rotary valve housing 50. As shown in fig. 7-8, when the valve core 52 rotates and drives the slurry pipe to be at the waste water discharging position, the slurry pipe is kept at the waste water discharging position, that is, the slurry pipe is located at the waste water box position, because the stop protrusion 512 cooperates with the stop baffle 502 on the rotary valve housing 50.
Specifically, in this embodiment, the waste water box is located right behind the pulp receiving cup, and the distance between the two stop lugs has a 90 ° rotation angle, so that in the food processing process, the valve core is rotated for one circle, and the valve core is ensured to be in the rotary valve closing state, that is, the communication inlet and the pulp outlet are in the non-conducting state, and the pulp outlet pipe is ensured to be in the holding state, that is, in the pulp outlet position or the waste water outlet position. This is known on certain food processors.
If the food processor controls the valve core to rotate clockwise, when the pulp discharge pipe does not rotate along with the valve core any more, the pulp discharge pipe is positioned at the pulp receiving position, and when the control valve core rotates anticlockwise at the moment, when the pulp discharge pipe does not rotate along with the valve core, the pulp discharge pipe is positioned at the waste water discharge position.
After the food processor finishes pulping, the valve core is controlled to rotate clockwise until the communication between the communicating inlet hole and the pulp discharging hole is detected, at the moment, if the pulp discharging pipe is positioned at the pulp discharging position, the pulp discharging pipe cannot rotate along with the valve core due to the existence of the stop lug, so the pulp discharging pipe is always positioned at the pulp discharging position, and the smooth pulp discharging is ensured; at the moment, if the grout discharging pipe is located at the position of the drained water, the grout discharging pipe can rotate along with the valve core until the grout discharging pipe rotates to the position of the drained grout, and when the position of the valve core is detected, the distance phase difference between the two positions is 180 degrees, so that the difference between the stop lugs is smaller than the rotation angle, and the grout discharging rotary valve can be located at a fixed position when the communicating inlet hole is communicated with the grout discharging hole, namely, the grout discharging pipe rotates along with the valve core only when the communicating inlet hole is not communicated with the grout discharging hole.
When the food processor needs to discharge waste water, the valve core is controlled to rotate anticlockwise until the communication inlet hole is communicated with the pulp discharge hole, and at the moment, if the pulp discharge pipe is located at a waste water discharge position, the pulp discharge pipe cannot rotate along with the valve core due to the existence of the stop lug, so that the pulp discharge pipe is always located at the waste water discharge position, and the waste water discharge is ensured to be carried out smoothly; at this moment, if the thick liquid pipe is in the row thick liquid position, then arrange the thick liquid pipe and can follow the case and rotate until the thick liquid pipe rotates to the waste water drainage position, because the case position detection time of the same reason, two position interval phase differences are 180 corner, so, the difference is less than this corner between the lug that ends, can ensure when intercommunication inlet and row thick liquid hole switch-on, arrange the thick liquid rotary valve in fixed position, that is to say, only when intercommunication inlet and row thick liquid hole non-conductive, arrange the thick liquid pipe and follow the case and rotate.
If the food processor controls the valve core to rotate clockwise, when the pulp discharge pipe does not rotate along with the valve core any more, the pulp discharge pipe is positioned at a waste water discharge position, and when the control valve core rotates anticlockwise at the moment, the pulp discharge pipe is positioned at a pulp discharge position when the pulp discharge pipe does not rotate along with the valve core.
After the food processor finishes pulping, the valve core is controlled to rotate anticlockwise until the communicating inlet hole is communicated with the pulp discharge hole, and at the moment, if the pulp discharge pipe is at the pulp discharge position, the pulp discharge pipe cannot rotate along with the valve core due to the existence of the stop lug, so that the pulp discharge pipe is always at the pulp discharge position, and the smooth pulp discharge is ensured; at the moment, if the grout discharging pipe is located at the position of the drained water, the grout discharging pipe can rotate along with the valve core until the grout discharging pipe rotates to the position of the drained grout, and when the position of the valve core is detected, the distance phase difference between the two positions is 180 degrees, so that the difference between the stop lugs is smaller than the rotation angle, and the grout discharging rotary valve can be located at a fixed position when the communicating inlet hole is communicated with the grout discharging hole, namely, the grout discharging pipe rotates along with the valve core only when the communicating inlet hole is not communicated with the grout discharging hole.
When the food processor needs to discharge waste water, the valve core is controlled to rotate clockwise until the communication inlet hole is communicated with the pulp discharge hole, and at the moment, if the pulp discharge pipe is positioned at a waste water discharge position, the pulp discharge pipe cannot rotate along with the valve core due to the existence of the stop lug, so that the pulp discharge pipe is always positioned at the waste water discharge position, and the waste water discharge is ensured to be carried out smoothly; at this moment, if arrange the thick liquid pipe in arrange the thick liquid position, then arrange the thick liquid pipe and can follow the case and rotate until arranging the thick liquid pipe and rotate to the waste water discharge position, because the case position detection time measuring, two position interval phase differences are 180 corner, so, end difference between the lug and be less than this corner, can ensure when intercommunication inlet hole and row thick liquid hole switch-on, arrange thick liquid rotary valve in fixed position, that is to say, only when intercommunication inlet hole and row thick liquid hole non-switch-on, arrange the thick liquid pipe and follow the case and rotate.
Of course, in this embodiment, when the slurry discharge rotary valve is closed, the slurry discharge rotary valve continues to rotate according to the original rotation direction of the slurry discharge rotary valve until the slurry discharge rotary valve is detected to be in the closed state.
Of course, besides the above features, in order to better discharge the slurry or the waste water, a sealing ring 57 is further provided between the slurry discharge pipe and the valve core, so as to ensure that the liquid flowing out of the valve core is not discharged to other places. Similarly, when the valve core 52 is installed in the rotary valve shell 50, the corresponding sealing silica gel 56 is also arranged, so that the valve core 52 can better move in the rotary valve shell, and the communication inlet 521 and the slurry discharge hole of the cup body are also sealed to prevent liquid leakage.
In addition, except that one Hall detection plate can be placed at the relative position of the slurry discharging holes, the Hall detection plate can detect and distinguish two magnets, and therefore whether the slurry discharging rotary valve is in a conducting state or a closing state can be known. Two Hall detection plates can also be arranged, as shown in figure 2, the Hall detection plate 55 is arranged at the position of the slurry discharge hole, so as to detect the slurry discharge position, at the moment, two detection plates are arranged, only one magnet can be arranged for detection, when the magnet triggers the Hall detection plates at different positions, the position of the slurry discharge rotary valve can be known, for example, the magnet is arranged at the position of the valve core, which is positioned in the communicated inlet hole, when the magnet triggers the Hall detection plate arranged at the position of the slurry discharge hole, the conduction of the slurry discharge rotary valve can be judged, when the magnet triggers the Hall detection plate arranged at the relative position of the slurry discharge hole, the closing of the slurry discharge rotary valve can be judged. Of course, the hall detection board can be used to know the corresponding rotation sequence, and other triggerable elements can be used for substitution, and the hall detection board belongs to the protection scope of the application under the principle of the technical idea of the application.
In this embodiment, to the rotation of arranging thick liquid pipe and case on being connected, the mode of having used buckle and draw-in groove is gone on, certainly also can set up the gear of mutually supporting on arranging thick liquid pipe and case, arrange thick liquid pipe or the gear on the case is the full distribution of non-perisporium, that is to say, at least one party is local gear, only when changeing the position that the gear acted on like this, arranges thick liquid pipe and follows the case and move, and when arranging thick liquid pipe and rotate to the position that needs to keep, then its corresponding gear cooperation is ended. At the moment, in an initial state, the slurry discharge pipe is in a waste discharge position, the slurry discharge rotary valve is in a closed state, the valve core and the gear of the slurry discharge pipe are in a half-gear state, namely, only half of the peripheral wall of the valve core or the slurry discharge pipe is provided with the gear, the gear ratio of the gear is not more than 2:1 and not less than 4:1, namely when the valve core rotates 180 degrees, the slurry discharge rotary valve rotates more than 45 degrees and not more than 90 degrees, the slurry discharge pipe can be ensured to rotate to the slurry discharge position when the valve core rotates and is maintained at the slurry discharge position when the slurry discharge rotary valve is conducted, and after slurry discharge is finished, the valve core continues to rotate to the closed position of the slurry discharge rotary valve. And vice versa. Of course, in order to conveniently set the gear ratio and the like, a corresponding limiting structure can be arranged, so that the control is more convenient.
In addition, the pulp discharge pipe can be connected with the valve core in an interference fit mode except for the mode of connecting the buckle salient points and the gear, and the pulp discharge pipe can be connected with the valve core in a direct connection mode by utilizing the pulp discharge pipe and the valve core, and of course, an indirect fit mode can also be used.
Utilize the case to drive the thick liquid pipe rotation and select corresponding thick liquid position of arranging, compare with prior art, reduce the step of change valve motor direct drive thick liquid pipe position, just also reduced corresponding drive gear, reduce corresponding cost, thereby the reduction of accessory simultaneously, thereby the corresponding because the accessory is invalid and the accessory is mutually supported the trouble that the problem leads to and is disappeared, has promoted the reliability of product. Meanwhile, in the aspect of control, the design of a control program of the slurry discharge pipe is lacked, and the corresponding flow is simplified, so that the corresponding algorithm design is simplified, the control error degree is effectively reduced, and the reliability of the product is also improved.
The valve core and the slurry discharging pipe are designed to be mutually rotatably connected, so that the position of the slurry discharging pipe can be more conveniently designed, the slurry discharging rotary valve is in a closed state when the slurry discharging pipe rotates, or the slurry discharging pipe rotates along with the valve core when the slurry discharging rotary valve is not switched on, and the slurry discharging pipe is prevented from rotating under the state that the slurry discharging rotary valve is switched on, so that slurry or waste water is discharged in a mess. That is to say, when the thick liquid pipe does not rotate to corresponding position, arrange the thick liquid hole and just can not link up with row thick liquid pipe, the setting of linkage like this ensures arranging thick liquid and the definite of the position of wasting discharge, can make simple structure again.
The limiting structure on the pulp discharging pipe is utilized to ensure that the pulp discharging pipe is positioned at a specific position, particularly when the pulp discharging pipe is positioned at two positions, the motion range of the pulp discharging pipe can be limited firstly, and the pulp discharging pipe can be positioned at a characteristic position secondly. Meanwhile, the matching mode of the valve core and the slurry discharge pipe is convenient to design, so that the structural design can be simplified and effective. In addition, during control, the meaning represented by the rotation direction is defined in advance, and in the working process, the rotation is controlled according to the set direction when needed, for example, the slurry discharging is defined to be clockwise rotation, the waste water discharging level rotates anticlockwise, when the slurry discharging is needed, the valve core is controlled to work clockwise, the slurry discharging pipe follows to the slurry discharging position and then does not rotate due to limitation, and vice versa. Meanwhile, the slurry discharge pipe and the valve core are in a normal state communication state, and only the valve core needs to be controlled to be communicated with the slurry discharge hole of the cup body, so that corresponding slurry discharge or wastewater discharge can be realized, and the control is simple and effective. In addition, the distance difference between the two stop protrusions arranged on the pulp discharge pipe is not larger than 90 degrees of rotation angle, which is equivalent to limiting the movement range of the pulp discharge pipe, and the pulp discharge pipe can be ensured to move from one specific position to another specific position, namely from the pulp discharge position to the waste water discharge position or from the waste water discharge position to the pulp discharge position, under the condition that the rotary valve is in a closed state to the rotary valve in a conducting state.
