Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
The piston is a drainage structure of the washing machine without the outer barrel impeller, when the washing machine without the outer barrel impeller is in a washing state, the piston extends into a drainage port of an inner barrel of the washing machine and is in sealing fit with the drainage port, when the washing machine without the outer barrel impeller is in a dehydration state, the piston is separated from the drainage port, and the inner barrel rotates at a high speed. The invention aims to provide a washing control method of an impeller washing machine without an outer cylinder, which is used for realizing the accurate control of a water discharge valve plug extending into a water outlet of the inner cylinder. The method comprises the following specific steps:
example 1:
the invention provides a washing control method of a pulsator washing machine without an outer cylinder, which comprises the following steps: controlling the driving device to act, and enabling the drainage valve plug connected with the driving device to contract towards the direction far away from the inner cylinder; when the driving device is triggered to the signal D, the driving device stops acting, the drainage valve plug retracts to the dewatering level, and when the drainage valve plug is positioned at the dewatering level, the drainage valve plug is separated from the drainage port on the inner drum 19 of the washing machine; controlling the inner cylinder to rotate to a matching position; the driving device is controlled to reversely act, and the drain valve plug extends towards the direction close to the inner cylinder under the action of the elasticity of the drain valve plug; and if so, judging that the drainage valve plug is inserted into the water outlet of the inner cylinder. The piston rod of drive arrangement and drainage valve plug is connected through the haulage rope, and during drive arrangement moved, can pull the piston rod and make the drainage valve plug to keeping away from the direction shrink of inner tube, when drive arrangement moved in the opposite direction, the drainage valve plug can be extended to the direction that is close to the inner tube under self elasticity effect. Because drive arrangement and drainage valve plug are through haulage rope flexonics, when drive arrangement opposite direction action to when stopping, at this moment, probably appear that the drainage valve plug does not insert the wash port on the inner tube 19 (drainage valve plug butt is in the bottom of inner tube, and drainage valve plug and drive arrangement's haulage rope are lax), consequently, need detect whether the drainage valve plug stretches into the outlet, trigger the B signal when the drainage valve plug upwards stretches out, then judge the outlet that the drainage valve plug inserted the inner tube. By the control method provided by the invention, the action of the drain valve plug can be controlled, so that the normal work of the pulsator washing machine without the outer barrel can be ensured.
With regard to whether the drain plug is able to trigger to the B signal when extended upward, the following is illustrated: the drainage valve plug cooperatees with detection device B, and when the drainage valve plug upwards extended, if let go of detection device B, then judge the outlet that the drainage valve plug inserted the inner tube, otherwise, then judge that the drainage valve plug has not inserted the outlet. The detection device B is preferably a normally open microswitch (hereinafter, the microswitch B is referred to as the detection device B), and the B signal is an off signal of the microswitch B.
The method for stopping the driving device by triggering the D signal by the driving device specifically includes: the driving device contacts the microswitch D; the driving device stops operating. The microswitch D is a normally closed microswitch, and is connected in series with the circuit of the drive device, i.e., is off when being pressed, and when the microswitch D is off, the drive device stops operating, and the D signal is a microswitch D off signal.
Regarding the reverse action of the control driving device, the drain valve plug extends towards the direction close to the inner cylinder under the action of the self elastic force, and the specific contents are as follows: the driving device is controlled to act, and the drain valve plug extends upwards under the action of the elasticity of the drain valve plug; the driving device contacts the microswitch C; the controller detects a state change signal of the microswitch C; the controller controls the driving device to stop acting; before the driving device stops, whether the drainage valve plug triggers a B signal or not is detected.
Before the inner barrel is controlled to rotate to the matching position, the following steps are also included: the driving device is controlled to reversely act, and the drain valve plug extends towards the direction close to the inner cylinder under the action of the elasticity of the drain valve plug; when the drain valve plug extends upwards, the signal A is triggered, the driving device stops acting, and the drain valve plug is located at the locating position.
With regard to "the A signal is triggered when the drain valve plug is extended upward", the following is exemplified: the drainage valve plug matches with detection device A, and when the drainage valve plug upwards extended, the detection device A was released, and drive arrangement stopped the action, and the drainage valve plug was located the position location. The detection device a is preferably a normally open microswitch (hereinafter, the microswitch a is used to represent the detection device a), and the a signal is an off signal of the microswitch a.
Regarding earlier control drainage valve plug and stretching out to the locating position, be for the convenience of blocking structure on drainage valve plug and the flange 21 and cooperate, promptly when the drainage valve plug for with the locating position, block structure 25 and contact with the drainage valve plug, realize the location of drainage valve plug and inner tube outlet, the accurate control drainage valve plug of being convenient for inserts the outlet of inner tube.
With respect to the stop structure 25, referring to FIG. 10, there is illustrated a flange 21 attached to the inner cartridge, there being a downwardly projecting stop structure 25 on the flange 21, the stop structure 25 being adapted to contact the drain plug in a seated position when the flange 21 is rotated; in addition, in order to increase the contact area between the blocking structure 25 and the drain valve plug, the surface of the blocking structure 25 contacting the drain valve plug is arranged to be an arc surface.
The present invention provides an embodiment in which the blocking structure 25 is disposed on the flange 21, and the structure of the blocking structure 25 is not limited to the structure illustrated in fig. 10, and other structures are also possible.
Before the inner barrel is controlled to rotate to the matching position, the following contents are specifically included: controlling a main driving device (the main driving device is a main motor, and the main driving device is connected with the inner cylinder and drives the inner cylinder to rotate) to drive the inner cylinder to rotate to a pre-matching position; controlling the driving device to act so as to enable the drain valve plug to extend upwards under the action of the elastic force of the drain valve plug; when the driving device releases and presses the microswitch A, the driving device stops acting, and at the moment, the drainage valve plug is positioned at the positioning position; after the driving device stops acting, the inner cylinder is controlled to rotate to the matching position. When the inner barrel is in the mated position, the drain plug contacts the stop 25 on the flange 21 (flange 21 is connected to inner barrel 19). When the drainage valve plug is detected to retract to a dewatering level, the inner cylinder is controlled to rotate at a low speed to a pre-matching position, then the drainage valve plug is controlled to extend upwards, when the driving device releases and presses the microswitch A, the driving device stops acting, the microswitch A can be a normally-open type microswitch, the default state is the switch disconnection, and the switch is closed after being extruded. Then the main driving device acts to drive the inner cylinder to continue rotating until the inner cylinder rotates to the matching position.
Before the upwards extension of drainage valve plug reaches the locating position, adjust the position of inner tube earlier, adjust the inner tube to the position of cooperateing in advance promptly, if do not adjust the position of inner tube, but directly upwards extend the drainage valve plug to the locating position, the drainage valve plug that probably appears leads to the drainage valve plug can not continue upwards to extend with blockking structure 25 looks butt, leads to unable normal work. Thus, the inner barrel is adjusted to the pre-engagement position prior to extending the drain plug upwardly to the seated position.
The main driving device is controlled to drive the inner cylinder to rotate to the pre-matching position, and the method comprises the following steps: the main driving device drives the inner cylinder to rotate at a low speedRotate and time the inner cylinder rotation time T 1 (ii) a When T is 1 ≤X S When a pre-in-place signal is detected, the main driving device is controlled to stop rotating; if T 1 >X S If the pre-in-place signal is not detected, a fault is reported; wherein, X S The time for rotating the inner cylinder for one circle at low speed is shown.
With respect to the "pre-bit signal", the following is illustrated: can set up magnet 24 on inner tube 19, set up magnetic induction switch 22 on water basin 20, after magnetic induction switch 22 sensed magnet 24, magnetic induction switch 22 closed, and the controller detects magnetism closure signal, puts in place the signal in advance promptly, and the control main drive device stops rotatoryly.
If the inner cylinder 19 rotates for a circle at a low speed, the controller does not receive the magnetic closing signal, which indicates that the magnetic induction switch 22 is damaged, and at this time, a fault prompt is sent out.
The inner cylinder is controlled to rotate to a matching position, and the method comprises the following steps: controlling the main driving device to drive the inner cylinder to rotate; and when the rotation reaches a certain time, controlling the main driving device to stop rotating. The rotation of the inner barrel to the mating position is specifically described as follows:
detecting a pre-in-place signal, and controlling the inner cylinder to continue rotating Y if the pre-in-place signal is not detected S Stopping, and judging that the inner cylinder reaches the matching position;
if the pre-in-place signal is detected, the inner cylinder is controlled to rotate and the rotation time T of the inner cylinder is counted 2 When T is 2 ≤Y S When the pre-in-place signal disappears, the inner cylinder is controlled to continue rotating Y S Then stopping, at the moment, judging that the inner cylinder has reached the matching position, and when T is reached 2 >Y S If the pre-in-place signal is not detected to disappear, a fault is reported.
Referring to fig. 11, the position relationship of the magnetic induction switch 22, the magnet 24, the blocking mechanism 2, etc. is illustrated, and fig. 11 illustrates that the inner cylinder 19 is located at the pre-fitting position, at this time, the magnetic induction switch 22 is close to the magnet 24; fig. 12 illustrates the upper inner barrel 19 in the engaged position, in which the magnetic switch 22 is away from the magnet 24 and the barrier structure 2 is in contact with the drain plug (in the seated position).
With respect to Y S Is prepared fromPre-calculating to obtain the value stored in the system, and if no fault occurs, rotating the inner cylinder from the pre-matching position to the matching position at a low speed S It is then possible to achieve that the blocking structure 25 is in contact with the drain valve plug in the seated position.
After the drainage valve plug is in the locating position, when the control inner tube is rotatory to the cooperation position, detect the signal that puts in place in advance earlier because, inner tube 19 reaches behind the cooperation position in advance, probably because inertia, continues to rotate, leads to magnetic induction switch 22 to keep away from the magnet on the inner tube for lead to magnetic induction switch 22 disconnection. Therefore, when the inner cylinder is controlled to rotate to the matching position, whether a pre-positioning signal (a magnetic induction switch closing signal) exists or not is judged firstly.
After the user selects the general washing mode, the control method comprises the following steps: recognizing a washing mode command; detecting whether the drain valve plug is in a washing position or not; if not, adjusting the drain valve plug to the washing position. When the washing mode is carried out, whether the drainage valve plug is positioned at a washing position or not is judged, namely whether the drainage valve plug is inserted into a water outlet of the inner cylinder and is in sealing fit with the water outlet; it is also ensured that the washing machine can normally perform the washing mode.
Adjusting the drain valve plug to a washing position, which comprises the following steps; detecting whether the drain valve plug is in a dewatering level; if yes, directly adjusting the drain valve plug to a washing position; if not, the piston is controlled to contract to the dehydration position in the direction away from the inner cylinder, and then the drainage valve is adjusted to the washing position.
Regarding adjusting the drain valve plug to the washing position, the following control can be performed: controlling the drain valve plug to extend upwards; detecting whether the drain valve plug is positioned at a washing position; if the water draining valve is in the washing mode, the piston is controlled to contract to the dewatering position in the direction away from the inner cylinder, and then the water draining valve is adjusted to the washing position and then the washing mode is started.
Next, an embodiment of a drain valve plug is provided, wherein the movement of the drain valve plug can be controlled based on the control method provided by the present invention, so as to achieve precise control of the drain valve plug and increase the reliability of the control.

With regard to the assembly of the drain plug, the following is explained: the piston rod 4 and the sealing rubber 1 are installed by utilizing the deformation of rubber to a certain degree; mounting the bearing 5 on a cast support 6; the spring 3 penetrates into the assembled piston rod 4 and sealing rubber 1 assembly, the piston rod 4 penetrates through the bearing 8, the spring 3 is arranged between the piston rod 4 and the casting support 6, and the spring 3 is extruded to enable the positioning column 101 of the sealing rubber 1 to be correspondingly installed in the installation hole of the casting support 6, so that the installation of the parts is realized; installing a microswitch B7, a microswitch C9, a microswitch D11, a microswitch A14, a forward and reverse rotation motor 16 and a mechanical protection 17 on a motor bracket 12; the hole in the middle of the motor support 12 is matched with the piston rod 4, the upper part of the traction rope 13 penetrates into the middle part of the piston rod 4, the traction rope 13 winds around the cam 10, the cam 10 is matched with the forward and reverse rotation motor 16, and the cam 10, the traction rope 13 and the forward and reverse rotation motor 16 are fixed in a certain mechanical mode. Above complete the equipment of whole piston part, the piston integral erection that will assemble again finishes on water collector 20: the lower edge of the hole of the piston-mounting part on the water receiving basin 20 is aligned with the corresponding 103 of the sealing rubber 1, and the piston and the water receiving basin 20 are fixedly mounted through screws.
Partial component functions of the drain valve plug:
sealing rubber 1: in the washing state (water-sealing state), the drain port of the inner cylinder 19 is closed, and the cast bracket 6 and the drip pan 20 are sealed to prevent water from flowing out of the drip pan.
And (3) metal wrapping 2: the function of reducing the friction resistance between the sealing rubber 1 and the blocking mechanism 25 on the flange is realized.

Mechanical protection 17: when the motor cannot stop rotating within a safe range due to problems, the mechanical protection limits the rotation of the motor shaft so as to prevent the motor shaft from continuously driving the cam 10 to rotate and break the traction rope 13 to destroy the whole mechanism.
The working principle of the drain valve plug is as follows:
the drain valve plug is fixedly mounted with a water receiving basin 20 (water receiving basin: temporary storage device, the interior of the washing machine is free from water during the washing stage, only receives water during the dehydration stage, and is externally connected with a drain pipe to discharge water). Assuming that the default state is a dehydration state, when entering a washing stage, the drain valve plug 16 starts to rotate anticlockwise to drive the cam 10 to rotate anticlockwise, at the moment, the traction rope 13 is released, the piston rod 4 moves upwards under the elastic force of the spring 3, the forward and reverse rotation motor 16 stops rotating, at the moment, the drain valve plug is in a washing state; when the washing stage is finished and the dewatering stage needs to be started, the motor 16 rotates clockwise, the traction rope 13 is pulled down at the moment, the piston rod 4 is pulled down, the forward and reverse rotation motor 16 stops rotating, the drainage valve plug returns to the drainage state at the moment, and the drainage valve plug is positioned at the dewatering level.
Because the positive and negative rotation motor 16 can rotate positively and negatively, and the length of the traction rope 13 is limited, the rotation and stop of the positive and negative rotation motor 16 are realized by depending on the change of 4 microswitch signals, and the microswitch generally does not easily break down, but once the motor fails to operate according to ideal logic, the traction rope 13 can be pulled down continuously, the integral structure of the piston is finally damaged, and the traction rope breaks down, so that the whole function is lost. Therefore, a mechanical protection 17 is added, the mechanical protection 17 is connected with a motor shaft of the positive and negative rotation motor 16, if the forward and reverse motor 16 still does not stop rotating after pressing the microswitch D, the forward and reverse motor 16 will continue to rotate counterclockwise with the mechanical protection 17, the forward and reverse motor and the mechanical protection 17 will continue to rotate for a short distance, if, within this allowable tolerance range, the counter-rotating motor 16 has not stopped rotating (i.e. has not received a stop signal), the stop signal is not received by default, the mechanical guard 17 is blocked by the structure on the motor bracket 12, the mechanical guard 17 cannot rotate counterclockwise, the output shaft of the forward/reverse rotation motor 16 cannot rotate continuously, the forward/reverse rotation motor 16 is locked, according to the protection mechanism, the temperature is too high after the locked rotor is in a certain time, and the alarm can be directly sent out, so that the motor can be burnt, but the piston structure is reserved.
By adopting the control method provided by the invention, the control process of the drainage valve plug is as follows:
as shown in fig. 13, for the flow chart after the user selects the normal washing mode, firstly, the forward/reverse motor 16 is given a signal for a certain time (the certain time is the time of half a circle of cam rotation), which is because there is a sudden power failure, after the power failure, if there is no power failure memory function (there is no power failure memory function in general) after the power failure, it is impossible to accurately determine which stage the drain valve plug is in, and after the power failure, the washing program is selected, the drain valve plug must be in the washing state, so the forward/reverse motor rotation instruction is directly given, if the drain valve plug is in the washing state, the microswitch C is in the squeezed state, the microswitch C is a normally closed microswitch, i.e. the microswitch C is changed from the closed state to the open state after being squeezed, when the controller detects the open state of the microswitch C, giving a command of stopping the rotation of the forward and reverse rotating motor; if the drain valve plug is aligned with the drain opening of the inner barrel (but is in a non-washing position), the forward and reverse rotating motor 13 receives a signal to rotate, and the drain valve plug rises to close the drain opening to realize sealing and enter a washing state; if drainage valve plug and outlet do not align this moment, positive reverse motor 13 receives the signal after and rotates, whether carry out the judgement that the drainage valve plug is in the washing state again, micro-gap switch A and micro-gap switch B be whether loosen and present the off-state promptly, micro-gap switch C has or not by the extrusion and present the off-state, if micro-gap switch A, micro-gap switch B, micro-gap switch C's all disconnection, judge that the drainage valve plug is in the washing state, then directly get into the washing mode, otherwise, the drainage valve plug gets into the dehydration state earlier, get into the washing state by the dehydration state again, washing machine gets into normal washing dehydration flow afterwards.
Referring to fig. 18, a flowchart after selecting a general washing mode for a user, i.e., control, may also be as follows: firstly, the drain valve plug can be judged not to be in a washing state, namely whether the microswitch A and the microswitch B are not extruded to present a switch off state or not, the microswitch C is extruded to present the switch off state or not, if the microswitch A, the microswitch B and the microswitch C are all disconnected, the drain valve plug is judged to be in the washing state, then the drain valve plug directly enters a washing mode, otherwise, the drain valve plug firstly enters a dewatering state, then the drain valve plug enters the washing state from the dewatering state, and then the washing machine enters a normal washing and dewatering process.
As shown in fig. 14, for the flow of the drain valve plug entering into the dewatering state, that is, the forward and reverse rotation motor 16 is driven clockwise (clockwise and counterclockwise determination is performed at the angle of fig. 1), the forward and reverse rotation motor 16 drives the cam 10 to rotate clockwise, the cam 10 rotates, the pulling rope 13 is wound in the rotating groove of the cam 10 in a rotating manner, so that the pulling rope 13 pulls the piston rod 4 to move down, if the drain valve plug enters into the dewatering level from the washing position, the cam rotates to release the microswitch C9 first, if the drain valve plug is not at any position of the washing position, the piston rod 4 moves down to touch the extruding microswitch B first, then the microswitch a is pressed under extrusion, the forward and reverse rotation motor 16 rotates continuously, the cam 10 rotates continuously, the salient point on the cam 10 extrudes the microswitch D, because the microswitch D is a normally closed type microswitch, and is connected in series with a forward rotation control circuit of the forward and reverse rotation motor 18, that is, after the microswitch D is pressed, the switch is changed from the closed state to the open state, the forward rotation circuit of the forward and reverse rotation motor is disconnected, that is, the forward and reverse rotation motor 16 stops rotating. When the controller detects that the micro switch B and the micro switch A are in a closed state and the micro switch D is in an open state, the drain valve plug is considered to be in a dehydration state; if not, reporting the fault.
As shown in fig. 15, after the drain valve plug enters the dewatering state, the washing machine is driven to enter the washing state process, the main motor is driven to enter the positioning program 1, after the positioning program 1 is finished, the forward and reverse rotation motor 16 is driven to rotate counterclockwise, when the piston rod 4 moves upwards to release the microswitch a and the microswitch a is detected to be changed from the closed state to the open state, a command for stopping the rotation of the forward and reverse rotation motor 16 is given, and at this time, the position of the drain valve plug is in the position shown in fig. 5-6, namely, the positioning position; after the positioning position is reached, the main motor is driven to execute the positioning program 2, after the positioning program is completed, the forward and reverse motor 16 is driven to continue to rotate anticlockwise, the cam 10 continues to rotate, the convex points on the cam can extrude the microswitch C, the microswitch C is a normally-closed microswitch, namely the microswitch C is changed from a closed state to an open state after being extruded, and when the controller detects the open state of the microswitch C, an instruction for stopping the rotation of the forward and reverse motor is given at the moment. And judging the states of the microswitch A, the microswitch B and the microswitch C, judging whether the microswitch A, B is in an off state and the microswitch C is in an off state, if so, indicating that the drain valve plug enters a washing state, and if not, directly reporting the fault.
As shown in fig. 16, regarding the flow chart of the positioning program 1, firstly, the main motor is driven to rotate at a low speed (assuming that Xs is required for one rotation at the low speed), and the timing is started, the time is T1, within the period that T1 is not more than Xs, the magnetic induction switch 22 sends out a closing signal (the closing signal is the positioning signal, when the magnetic induction switch 22 on the water receiving basin 20 is close to the magnet 24 on the inner barrel, the magnetic induction switch 22 is closed), after receiving the closing signal, a signal that the main motor stops rotating is sent out, and if T1 exceeds Xs, the fault is directly reported.
As shown in fig. 17, it is a flowchart of the positioning procedure 2, at this time, the drain valve plug is in the positioning position, at this time, it is first determined whether the magnetic induction switch 22 is closed, and if the magnetic induction switch 22 is not closed, the main motor is directly driven to continue to rotate Ys (Ys is a preset time, and Ys is calculated according to the rotation speed of the inner cylinder, the position of the magnet, and the like, and the drain valve plug is always located above the drain opening); if the magnetic induction switch 22 is detected to be closed, the main motor is driven to rotate, timing T2 is started, whether the magnetic induction switch 22 is changed from closed to open within Ys which is less than or equal to T2 is detected, if yes, the main motor is driven to continue rotating Ys, then the main motor stops rotating, and at the moment, the inner cylinder rotates to a matching position; if not, otherwise, reporting the fault.
In the positioning procedure 2, it is determined whether the magnetic induction switch 22 is closed, because the inner cylinder 19 can continue to rotate due to inertia, which causes the magnetic induction switch 22 to move away from the magnet on the inner cylinder, which causes the magnetic induction switch 22 to be opened.
