Thus, the following detailed description of the embodiments of the invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be made by a person skilled in the art without making any inventive effort, are intended to be within the scope of the present invention.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures. Meanwhile, in the description of the present invention, the terms "first", "second", and the like are used only to distinguish the description, and are not to be construed as indicating or implying relative importance.
Fig. 1 is a block schematic diagram of a washing machine 100. Fig. 2 is a schematic diagram of a washing machine 100 according to a preferred embodiment of the present invention. As shown in fig. 1 and 2, the washing machine 100 includes a control circuit board 110, a first sensor 112, and a second sensor 114.
The control circuit board 110, the first sensor 112 and the second sensor 114 are electrically connected directly or indirectly to each other, so as to realize data transmission or interaction. For example, the components may be electrically connected to each other via one or more communication buses or signal lines.
In this embodiment, as shown in fig. 2, the washing machine 100 includes a tub 115, and the tub 115 is provided with a water inlet 111.
The first sensor 112 is arranged at the water inlet 111, the first sensor 112 being adapted to detect a first water quality parameter of water entering through the water inlet 111.
In this embodiment, the first water quality parameter may be PH, resistivity, conductivity, etc. In this embodiment, the first sensor 112 is disposed at the water inlet 111, and it can be understood that the first water quality parameter is a water quality parameter of water for cleaning clothes, such as tap water.
The second sensor 114 is installed inside the tub 115, and the second sensor 114 is used for detecting a second water quality parameter of water in the tub 115.
In this embodiment, the second water quality parameter may be PH, resistivity, conductivity, etc. In this embodiment, the second water quality parameter is a water quality parameter of water in the tub 115. For example, if the washing machine 100 is being used to wash clothes, the second water quality parameter may be indicative of the level of detergent that may be present on the clothes inside the tub 115.
The control circuit board 110 may be installed at any position of the washing machine 100. The control circuit board 110 is used for controlling the operation of the washing machine 100 and receiving signals transmitted by the first sensor 112.
In use, the control circuit controls the washing machine 100 to perform rinsing until the second water quality parameter is within the set range of the first water quality parameter. In one embodiment, the control circuit board 110 receives the first water quality parameter transmitted by the first sensor 112 and the second water quality parameter transmitted by the second sensor 114. The control circuit board 110 compares the values of the first water quality parameter and the second water quality parameter to obtain a difference value between the first water quality parameter and the second water quality parameter. In one example, if the ratio of the difference between the value of the first water quality parameter and the second water quality parameter to the first water quality parameter is less than 5%, for example, the ratio of the difference to the first water quality parameter is 3%, the washing machine 100 does not perform rinsing, and the washing machine 100 enters a dehydration mode.
In one embodiment, the first sensor 112 and the second sensor 114 are PH sensors; the first sensor 112 is used for detecting the pH value of the water entering through the water inlet 111, and the second sensor 114 is used for detecting the pH value of the water in the tub 115. The first water quality parameter is the PH of the water entering the water inlet 111, and the second water quality parameter is the PH of the water in the tub 115.
It is known that the PH of a detergent is generally alkaline and tap water is relatively neutral, and therefore, the higher the content of the detergent, the higher the PH of the mixed water of the detergent and tap water. In one example, the PH of the various water samples obtained by the experimental determination is as follows: tap water for cleaning laundry has a PH of 7.57; the PH of the washing water of the washing machine 100 after the primary washing is 10.55; the PH value of the rinsing water after one rinsing is 9.96; the PH value of the rinsing water after the rinsing twice is 8.06; the PH value of the rinsing water after three times of rinsing is 7.78; the pH of the rinse water after four rinses was 7.72. From the above test data, the pH of the rinse water was significantly lowered and gradually approached the pH of the tap water as the number of rinses increased. The degree of rinsing of the laundry in the tub of the washing machine 100 can be judged by judging the PH value of the rinsing water in the tub and the tap water.
In one example, the second sensor 114 of the washing machine 100 tests the PH value of the rinsing water in the tub 115 in real time or at preset intervals, the control circuit board 110 determines the ratio of the difference between the PH value of the rinsing water in the tub 115 and the PH value of the tap water at the water inlet 111 to the PH value of the tap water, and if the ratio of the difference between the PH value of the rinsing water in the tub 115 and the PH value of the tap water at the water inlet 111 to the PH value of the tap water is greater than 3%, the washing machine 100 continues to inject tap water for re-rinsing after performing the draining operation; if the ratio of the difference between the PH of the rinsing water in the tub 115 and the PH of the tap water at the inlet 111 to the PH of the tap water is less than 3%, the washing machine 100 enters a dehydrating mode after performing a draining operation.
In another embodiment, the first sensor 112 and the second sensor 114 are resistivity sensors; the first sensor 112 is used to detect the resistivity value of the water entering through the water inlet 111, and the second sensor 114 is used to detect the resistivity value of the water in the tub 115.
In one example, resistivity values of different water samples obtained by experimental determination are different, and the specific examples are as follows: tap water for cleaning laundry has a resistivity of 4.41kΩ·cm; the washing water of the washing machine 100 after primary washing is 1.78KΩ & cm, and the resistivity of the rinsing water after primary rinsing is 3.89KΩ & cm; the resistivity of the rinsing water after the rinsing twice is 4.37KΩ·cm; the rinsing water after three times of rinsing was 4.32KΩ·cm. From the above data, it can be seen that the resistivity value of the rinse water is closer to that of the tap water as the number of rinsing times increases. The degree of rinsing of the laundry in the tub of the washing machine 100 can be judged by the judging of the resistivity value of the rinse water in the tub and the tap water.
In one example, the second sensor 114 of the washing machine 100 tests the resistivity value of the rinsing water inside the tub 115 in real time or at preset intervals, the control circuit board 110 determines the ratio of the difference between the resistivity value of the rinsing water inside the tub 115 and the resistivity value of the tap water at the water inlet 111 to the resistivity value of the tap water, and if the ratio of the difference between the resistivity value of the rinsing water inside the tub 115 and the resistivity value of the tap water at the water inlet 111 to the resistivity value of the tap water is greater than 10%, the washing machine 100 continues to inject tap water for re-rinsing after performing the draining operation; if the ratio of the difference between the resistivity value of the rinsing water in the tub 115 and the resistivity value of the tap water at the inlet 111 to the resistivity value of the tap water is less than 10%, the washing machine 100 enters a dehydrating mode after performing a draining operation.
In yet another embodiment, the first sensor 112 and the second sensor 114 are water tension sensors; the first sensor 112 is used for testing the tension value of the water entering the water inlet 111; the second sensor 112 is used for testing the tension value of the water in the barrel 115; the first water quality parameter comprises a tension value of water entering through the water inlet 111; the second water quality parameter includes a tension value of water in the tub 115.
In one example, the detergent content of the tested mixed liquor can be obtained by testing the tension value of the resulting water. When the tension value of the water in the tub 115 is approximately close to the tension value of the water entering the water inlet 111, it means that the content of the detergent is smaller.
In this embodiment, when the first sensor 112 or the second sensor 114 needs to test the tension value of the mixed water, a capillary tube is inserted into the mixed liquid to be tested, and inert gas is slowly introduced into the tube to apply pressure to the mixed liquid to be tested, so that bubbles can be formed at the tube end to escape. When the capillary tube used has a small diameter, it can be assumed that the bubbles generated are part of a sphere, but the radius of curvature of the bubbles will change with the pressure change of the inert gas during the generation and development of the bubbles. When the bubble is exactly hemispherical in shape, the radius of curvature of the bubble is at least exactly equal to the capillary radius. If the inert gas is continued at this point, the bubble may burst and rapidly escape from the tube end or burst.
The capillary tube is connected with a pressure sensor, the density of liquid used by the pressure sensor is P, the height difference of two liquid columns is Deltal, and then the maximum pressure DeltaP max of bubbles can be determined through experiments.
Wherein,The gamma represents the tension value of the mixed solution to be tested; r represents the radius of the capillary, which can also be understood as the radius when the shape of the bubble is exactly hemispherical; ρ represents the liquid density; g represents a constant, g=9.8N/kg.
The sensor according to the above embodiment determines the detergent content in the water in the tub 115 according to the tension value of the sensor test water, and may effectively test the detergent content in different types of mixed solutions regardless of the type of detergent.
The water tension test method is only used for illustrating the feasibility of the water tension sensing measurement, and is not limited to the water tension sensor implementation mode.
In this embodiment, the second sensor 114 may be disposed at the bottom of the tub 115 or at the inner wall of the tub 115.
In one embodiment, the second sensor 114 is mounted below the highest water level of the tub 115. As shown in fig. 2, in an example, the second sensor 114 is disposed below the point P where the highest water level of the tub 115 is P. In this embodiment, the second sensor 114 is installed below the highest water level of the tub 115, so that the second sensor 114 can prevent the second water quality parameter of the water in the tub 115 from being not detected.
In this embodiment, the control circuit board 110 may be an integrated circuit chip with signal processing capability. The control circuit board 110 may be a general-purpose processor, including a central processing unit (Central Processing Unit, abbreviated as CPU), a network processor (Network Processor, abbreviated as NP), etc.; but also Digital Signal Processors (DSPs), application Specific Integrated Circuits (ASICs), field Programmable Gate Arrays (FPGAs) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components. The disclosed methods, steps, and logic blocks in the embodiments of the present invention may be implemented or performed. A general purpose processor may be a microprocessor or the processor may be any conventional processor or the like.
It will be appreciated by those skilled in the art that the structure shown in fig. 2 is merely illustrative and is not limiting of the structure of the washing machine 100. For example, the washing machine 100 may also include more or fewer components than shown in fig. 2, or have a different configuration than shown in fig. 2.
The washing machine 100 of the present embodiment may further include the Memory (not shown) which may be, but is not limited to, a random access Memory (Random Access Memory, RAM), a Read Only Memory (ROM), a programmable Read Only Memory (Programmable Read-Only Memory, PROM), an erasable Read Only Memory (Erasable Programmable Read-Only Memory, EPROM), an electrically erasable Read Only Memory (Electric Erasable Programmable Read-Only Memory, EEPROM), etc. The memory is configured to store a program, and the control circuit board 110 executes the program after receiving an execution instruction, and the method executed by the washing machine 100 defined by the process disclosed in any embodiment of the present invention may be applied to the control circuit board 110 or implemented by the control circuit board 110.
According to the washing machine 100 of the present embodiment, by setting a plurality of sensors on the washing machine 100 to detect water quality parameters, the control circuit board 110 controls the operation of the washing machine 100 by comparing the water quality parameters detected by the two sensors, so that the washing machine 100 can more intelligently identify the washing degree, and the washing efficiency of the washing machine 100 is improved.
In other embodiments, referring to FIG. 2, the first sensor 112 and the second sensor 114 are PH sensors; the first sensor 112 is used for detecting the pH value of the water entering through the water inlet 111, and the second sensor 114 is used for detecting the pH value of the water in the tub 115.
The washing machine 100 further includes: third sensor 116 and fourth sensor 118, the third sensor 116 and fourth sensor 118 being resistivity sensors.
The third sensor 116 is mounted at the water inlet 111, the third sensor 116 being for detecting a resistivity value of water entering through the water inlet 111.
The fourth sensor 118 is installed inside the tub 115, and the fourth sensor 118 is used to detect a resistivity value of water in the tub 115.
Wherein the first water quality parameter includes a PH value detected by the first sensor 112 and a resistivity value detected by a third sensor 116; the second water quality parameter includes the PH value detected by the second sensor 114 and the resistivity value detected by the fourth sensor 118.
In one example, when the ratio of the difference of the PH value of the rinsing water inside the tub 115 to the PH value of the tap water at the inlet 111 to the PH value of the tap water is less than 3% and the ratio of the difference of the resistivity value of the rinsing water inside the tub 115 to the resistivity value of the tap water at the inlet 111 to the resistivity value of the tap water is less than 10%, the washing machine 100 enters the dehydrating mode after performing the draining operation. It is understood that the ratio of 3% and the ratio of 10% are only ratios in one example, and those skilled in the art can set the ratios according to the need to make the rinsing force of the washing machine 100 stronger.
In another example, when the ratio of the difference of the PH value of the rinsing water inside the tub 115 to the PH value of the tap water at the inlet 111 to the PH value of the tap water is less than 3% or the ratio of the difference of the resistivity value of the rinsing water inside the tub 115 to the resistivity value of the tap water at the inlet 111 to the resistivity value of the tap water is less than 10%, the washing machine 100 enters the dehydrating mode after performing the draining operation.
In this embodiment, the fourth sensor 118 is installed at a position lower than the highest water level of the tub 115. As shown in fig. 2, the fourth sensor 118 is installed at a position lower than the highest water level P of the tub 115.
In this embodiment, the washing machine 100 may further include the input/output unit for providing a user with an input instruction. The input/output unit may be, but is not limited to, a control button provided on the washing machine 100, or the like. The washing machine 100 further includes a first control button 119 and a second control button 121, wherein the first control button 119 is used for controlling the first sensor 112 and the second sensor 114 to be turned on or off. The second control button 121 is used to control the third sensor 116 and the fourth sensor 118 to be turned on or off.
According to the washing machine 100 of the present embodiment, sensors for testing different water quality parameters are provided on the washing machine 100 to improve the accuracy of the control circuit board 110 in judging the possibility of detergent containing of the rinse water in the tub 115.
In other embodiments, referring again to fig. 2, the washing machine 100 further includes a drain hole 113, and a fifth sensor 120 is installed at the drain hole 113.
The fifth sensor 120 is a sensor having the same function as the first sensor 112, and the fifth sensor 120 is configured to detect a third water quality parameter of the water discharged from the drain hole 113 and transmit the detected third water quality parameter to the control circuit board 110.
In use, if the control circuit board 110 determines that the third water quality parameter is not within the set range of the first water quality parameter, the washing machine 100 is controlled to enter the rinsing mode again.
For example, if the first sensor 112 is a PH sensor, the fifth sensor 120 is also a PH sensor; if the first sensor 112 is a resistive sensor, the fifth sensor 120 is also a resistive sensor.
According to the washing machine 100 of the present embodiment, the washing degree of the washing machine 100 to the laundry may be further determined by the third water quality parameter and the first water quality parameter, and the control circuit board 110 may control the washing machine 100 to enter the rinsing mode again to improve the cleaning degree of the laundry when the third water quality parameter is not within the setting range of the first water quality parameter.
In other embodiments, referring to FIG. 3, the washing machine 100 may also have a display 122 that provides an interactive interface (e.g., user interface) between the washing machine 100 and a user or for displaying image data to a user reference. In this embodiment, the display 122 may be a liquid crystal display or a touch display. In the case of a touch display, the touch display may be a capacitive touch screen or a resistive touch screen, etc. supporting single-point and multi-point touch operations. Supporting single-point and multi-point touch operations means that the touch display can sense touch operations simultaneously generated from one or more positions on the touch display, and the sensed touch operations are passed to the processor for calculation and processing. In this embodiment, the display 122 is configured to display operation parameters of the washing machine 100, where the operation parameters include a first water quality parameter detected by the first sensor 112, and a second water quality parameter detected by the second sensor 114. Further, the display 122 may also display information such as the running time of the washing machine 100.
According to the washing machine 100 in the present embodiment, displaying the parameters in the washing machine 100 on the display 122 can enable the user to know the current state of the washing machine 100 and the data that may be detected during the washing process, so that the user can know the washing state more.
In this embodiment, as shown in fig. 3, the washing machine 100 is further provided with an alarm 123, the alarm 123 is electrically connected to the control circuit board 110, and when the second water quality parameter received by the control circuit board 110 is within the set range of the first water quality parameter, an alarm sound is generated to prompt the user about the current state of the washing machine 100.
In one example, the alarm may alert the user that the laundry of the washing machine 100 has reached a default level of cleanliness, and if the user still needs to perform rinsing, the washing machine 100 may be operated to perform a further rinsing.
According to the washing machine 100 of the present embodiment, the demands of different users can be satisfied, and the user with higher cleanliness requirements can again rinse instead of entering the spin-drying mode by default.
Referring to fig. 4, a flowchart of a method for controlling a rinsing cycle of a washing machine 100 applied to the washing machine shown in fig. 1 according to a preferred embodiment of the present invention is shown. The specific flow shown in fig. 4 will be described in detail.
