Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the present invention can be applied to a washing machine as shown in the figure, which is a structural cross-sectional view of a double-drum washing machine, wherein a large drum is shown as a first inner drum 100, a small drum is shown as a second inner drum 200, the second inner drum 200 can be installed or not according to the use of a user, a water level sensor can be used for detecting the water level in the first inner drum 100, the washing machine shown in the figure is for explaining the present invention, and the method for selecting a washing program of a washing machine in the present invention is applied to other types of washing machines and is within the protection scope of the present invention.
Furthermore, a water level sensor is mounted on the first inner barrel 100, and can detect the water level in the first inner barrel 100, and supply water in the first inner barrel 100 according to the water level, if the second inner barrel 200 is mounted, the indication of the water level sensor only displays the water level of the first inner barrel 100, but under the condition that the second inner barrel 200 is mounted, the supply water for the washing machine firstly enters the second inner barrel 200, and only after the water overflows, the supply water enters the first inner barrel 100; when the preset volume of water is supplied to the washing machine, the preset volume of water should be smaller than the volume of the second inner cylinder 100, so that the water is only in the second inner cylinder 200 or a very small amount of water is splashed into the first inner cylinder 100, and when the preset volume of water is supplied to the washing machine (the preset volume is substantially equal to the volume of the second inner cylinder 200) under the condition that the second inner cylinder 200 is installed, the water level sensor theoretically obtains the same water level twice before and after the preset volume of water is supplied to the washing machine.
The invention provides a washing program selecting method of a washing machine, wherein the washing machine comprises a water level sensor, a flow meter, an outer barrel (not shown in the figure) and a first inner barrel and a second inner barrel which are rotationally arranged in the outer barrel, the first inner barrel is provided with the water level sensor for detecting the water inflow of the first inner barrel, the water inlet valve of the washing machine is provided with the flow meter, and the water level sensor and the flow meter are mainly used for detecting the state of the washing machine and selecting a washing program according to the state of the washing machine; to assist understanding, fig. 2 shows a schematic diagram of the overall steps of a washing program selection method of a washing machine implemented by using a water level sensor and a flow meter alternately.
Referring to fig. 3, in an embodiment of a washing course selection method of a washing machine, the method includes the steps of:
step S10, when detecting the washing machine starting, acquiring a first water level parameter detected by a water level sensor;
the water level parameter is the indication number representing the water level, in the invention, the water level frequency value obtained by the water level sensor is mainly used as the water level parameter, and the height of the water level frequency value is inversely proportional to the height of the water level, (it needs to be further explained that if other values representing the water level parameter are used, the water level frequency value in the invention is replaced by the water level frequency value, which is included in the protection range of the invention, for example, the water level frequency value is directly replaced by the water level), in combination with fig. 2, the current water level detected by the water level sensor when the washing machine is started, i.e. the first water level frequency value, is obtained, the first water level frequency value is represented by a, the water level sensor works normally, the obtained current water level frequency value of the first inner cylinder, i.e. the first water level frequency value a, is detected for the first time, in the washing program selecting method of the washing machine, the frequency value of the water level detected by the water level sensor when no water is determined is that the current water level is required for the first detection because the water in the washing machine is not completely discharged when the user performs the washing operation, and the water level is selected based on the variation of the water level in the washing program selection of the washing machine, which may occur in real situations).
Step S20, obtaining a second water level parameter detected again by the water level sensor based on the preset volume of water supplied to the washing machine by the flowmeter;
the method comprises the following steps that based on a preset water supply volume of a washing machine by a flowmeter, the washing machine automatic control program sends an instruction to a preset water inlet volume of a water inlet valve with the flowmeter (it needs to be explained that the preset volume is the same as the preset water inlet volume in the washing machine automatic control program), and the instruction content is as follows: when the water inlet valve with the flow meter enters the preset water volume, the water level sensor acquires a water level frequency value, namely a second water level frequency value B (shown in figure 2), when the water inlet valve with the flow meter enters the preset water volume, the water level sensor detects that the numerical value of the first inner cylinder, namely the second water level frequency value B, is equal to the first water level frequency value A (B ═ A), otherwise, when the water with the preset volume enters the first inner cylinder, the water level sensor detects that the numerical value of the first inner cylinder, namely the second water level frequency value B, is not equal to the first water level frequency value A (B ≠ A), or B < A water level frequency value is inversely proportional to the water level; the flow meter can roughly determine the water inlet volume, and the change situation of the water level can be reversely deduced according to the water inlet volume in the washing program selection process of the washing machine.
And step S30, selecting a washing program of the washing machine according to the first water level parameter and the second water level parameter.
In the washing machine automatic control program, the water level data obtained twice, namely the first water level parameter and the second water level parameter, are subjected to certain operation, and the washing machine automatic control program selects the washing program of the washing machine according to the operation result.
In this embodiment, when the washing machine is detected to be started, a first water level parameter detected by a water level sensor is acquired, a second water level parameter detected again by the water level sensor is acquired based on a preset water supply volume of a flow meter for the washing machine, a washing program of the washing machine is selected according to the first water level parameter and the second water level parameter, the water level sensor and the flow meter are used alternately, after the state of the washing machine is detected, a user only performs one operation to start the washing machine, data are acquired and compared for multiple times in the program of the washing machine, then the washing program of the washing machine is selected automatically according to the result obtained by comparison, when manual multiple selections are performed, due to the fact that the operation of the washing machine is unfamiliar, the operation error caused by the operation of the washing machine cannot achieve the expected effect, and.
Referring to fig. 4, in another embodiment of the washing course selection method of the washing machine, step S30 includes:
step S31, comparing the first water level frequency value with the second water level frequency value, and obtaining the difference value of the first water level frequency value and the second water level frequency value as the variation of the current water level frequency value;
comparing the first water level frequency value a with the second water level frequency value B to obtain a variation C of the current water level frequency value in actual operation, and referring to fig. 2, the variation C of the current water level frequency value is a difference between the first water level frequency value a and the second water level frequency value B, (C ═ a-B, B ═ A, C ═ 0 when water enters the second inner cylinder, B ≠ A, C ═ a-B when water enters the first inner cylinder, and it needs to be explained that the water level frequency value is inversely proportional to the actual water level.
And step S32, comparing the variation of the current water level frequency value with the variation of the preset water level frequency value in the program, and selecting the washing program of the washing machine.
Comparing the variation C of the current water level frequency value with the variation M of the preset water level frequency value in the program, and combining with the graph 2, the variation C of the current water level is data monitored by a user in real time when the user uses the washing machine, the variation M of the variation rate of the preset water level is programming data of the washing machine leaving a factory, and the step of obtaining the variation M of the preset water level is as follows: the method comprises the steps of feeding a preset volume of water into a first inner barrel, obtaining a difference between values of water level frequency before and after the preset volume of water fed into the first inner barrel, obtaining a variable quantity M of a preset water level, and using the variable quantity M of the preset water level in an actual operation process of the washing machine (for example, the variable quantity M of the preset water level is set in a washing program of the washing machine, when a second inner barrel is not used, obtaining a value of a primary water level frequency, feeding the preset volume of water into the first inner barrel, obtaining a value of the primary water level frequency, obtaining a difference between the values of the two obtained water level frequencies, obtaining a variable quantity M of the value of the water level frequency, and storing the variable quantity M.
According to the variation M of the preset water level and the variation C of the actually operated water level, a washing program is selected (for example, when water enters the second inner tub, B ≠ A, C ═ a-B ≠ 0 ≠ M, when water enters the first inner tub, B ≠ A, C ≠ a-B ═ M, when water enters the second inner tub (small tub), the washing program of the washing machine corresponds to a small tub washing program, and when water enters the first inner tub (large tub), the washing program of the washing machine corresponds to a normal washing program).
In this embodiment, a first water level frequency value and a second water level frequency value are compared, a difference between the first water level frequency value and the second water level frequency value is obtained and is used as a variation of a current water level frequency value, the variation of the current water level frequency value is compared with a variation of a preset water level frequency value in a program, and a washing program of a washing machine is selected and selected; meanwhile, the water inlet volume of the flowmeter is utilized to reversely deduce the change condition of the water level; and comparing the first water level frequency value and the second water level frequency value obtained by the water level sensor, so as to select a washing program of the washing machine, ensure the accuracy of the data source selected by the washing program of the washing machine, and ensure that reliable data can be obtained at lower cost.
Referring to fig. 5, in still another embodiment of the washing course selection method of the washing machine, step S32 includes:
step S321, obtaining a difference value between the variation of the current water level frequency value and the variation of a preset water level frequency value as a water level frequency variation difference;
as shown in fig. 2, the difference between the variation of the current water level frequency value and the variation of the preset water level frequency value is obtained as a water level frequency variation difference, that is, a water level frequency variation difference N-M-C (when water enters the second drum, B-A, C-a-B-0, N-M-C-M, and when water enters the first drum, B ≠ A, C-a-B-M, N-M-C-0, it is necessary to account for the volume error of the entered water when the flow meter is in use, or the water in the second drum is splashed out, and an error in an error tolerance range may occur).
Step S322, comparing the water level frequency variation difference with a preset fixed value in the program, and if the water level frequency variation difference is larger than the preset fixed value in the program, selecting a small-drum washing program; and if the difference of the water level frequency change amount is less than or equal to a preset fixed value in the program, selecting a common washing program.
Comparing the water level frequency variation difference N obtained in step S321 with a preset fixed value Q (when water enters the second inner cylinder, B is A, C, a-B is 0, N is M-C is M, when water enters the first inner cylinder, B is not A, C, a-B is M, N, M-C is 0, Q is greater than 0 and is smaller than M, and is taken according to actual conditions) as shown in fig. 2 and 5, if the water level frequency variation difference is greater than the preset fixed value in the program (the accuracy rate is up to 100% in the programming of the washing machine according to data obtained by multiple tests), selecting a small cylinder washing program, and if the water level frequency variation difference is smaller than or equal to the preset fixed value in the program, selecting a normal washing program; and when the washing program is determined, the water inlet valve continues to feed water until the set value of the program is reached, and then the washing operation is carried out.
In the embodiment, the obtained water level frequency change quantity difference is compared with the preset fixed value, the washing machine program performs data comparison, and only a few milliseconds are needed for selecting the washing program of the washing machine according to the comparison result, so that the washing program of the existing washing machine can be quickly selected without influencing the normal work of the washing machine, and the method is quicker, more accurate and more intelligent than the method for actively selecting by a user.
Further, comparing the difference in the water level frequency variation amount with a fixed value preset in the program in step S322 includes:
and detecting a washing program of the washing machine, when a common washing program is selected, closing the flow meter, starting the water level sensor, controlling the water inlet valve to feed water and shielding the small barrel washing program, and when the small barrel washing program is selected, closing the water level sensor, starting the flow meter, controlling the water inlet valve to feed water and shielding the common washing program.
The washing program of the washing machine is detected, when the washing program is determined, the water inlet of the water valve continues until the program set value is reached, so that the washing program selection process of the washing machine is carried out at the water inlet stage in the program operation process of the washing machine, and when the washing program of the washing machine is determined, the corresponding program is started at the same time (for example, the selection of the common washing program corresponds to the soft washing, the standard washing and the quick washing in the mode of the common washing, the selection of the small-cylinder washing program corresponds to the soft washing, the standard washing and the quick washing in the mode of the small-cylinder washing, and the diversification of the small-cylinder washing program is realized, namely, each common program has the corresponding small-cylinder washing program).
Further, a common washing program is selected, the flowmeter is closed, the water level sensor is started to control the water inlet valve to feed water, if the water inlet of the flowmeter is continuously adopted, because the water inlet error of the flowmeter is large, a large cylinder is used for washing in the common washing program, the large volume accumulated error of the large cylinder (namely the first inner cylinder) is also relatively large, but the water inlet error of the water inlet valve controlled by the water level sensor is small, and meanwhile, the small cylinder washing program is shielded, so that the influence of the wrong operation of a user on the normal use of the washing machine is prevented; if a small cylinder (namely the second inner cylinder) washing program is selected, the water level sensor is closed, the flow meter is selected to control the water inlet valve to feed water, only one water level sensor is used for detecting the water level of the first inner cylinder in the scheme, the flow meter is adopted to control the water inlet aiming at the small cylinder with small water inlet amount in the small cylinder washing mode, and meanwhile, the influence of the misoperation of a user in the common washing program on the service life of the washing machine is shielded.
In the embodiment, aiming at the working conditions of the washing machine under various washing programs of the washing machine, the advantages and disadvantages of the cross use of the water level sensor and the flowmeter are explained, and according to the actual operation condition of a user, under the condition that the cost of the washing machine is not increased, the water inlet condition and the washing program selection of the double-drum washing machine can be more intelligently controlled by only using one water level sensor and one flowmeter; the invention detects the state of the washing machine and selects the program for automatic identification, thereby greatly reducing the hidden danger of safety accidents, reducing the manual operation and highlighting the intelligent health concept and promoting the development of energy-saving healthy washing machines.
Further, in still another embodiment of the washing course selecting method of the washing machine, the step S30 includes:
step S33, acquiring the ratio of the first water level frequency value and the second water level frequency value as the current water level frequency ratio;
with reference to fig. 2, a ratio of the first water level frequency value to the second water level frequency value is obtained, that is, a first water level frequency value a and a second water level frequency value B are obtained, where a/B is a current water level frequency ratio, and since the water level sensor detects a water level in the first inner cylinder, when the second inner cylinder is installed, inflow water may first enter the second inner cylinder, a preset volume of water may not enter the first inner cylinder, and at this time, the water level sensor measures B (where a is equal to B, and a/B is equal to 1, and water that may be splashed out is ignored), when the second inner cylinder is not installed, inflow water may enter the first inner cylinder, and at this time, the water level sensor measures B (where a is not equal to B or a > B, and a/B is not equal to 1 or a/B > 1).
And step S34, comparing the current water level frequency ratio with a preset water level frequency ratio in the program, if the current water level frequency ratio is larger than the preset water level frequency ratio in the program, selecting a common washing program, and if the current water level frequency ratio is smaller than or equal to the preset water level frequency ratio in the program, selecting a small drum washing program.
According to the change conditions of the first water level frequency value A and the second water level frequency value B, a water level frequency ratio is preset in a washing machine program according to early experimental data (the preset water level frequency ratio is a set value in the washing machine program, is obtained according to multiple experiments in the early period, is close to 1 and is measured according to actual conditions), when the ratio of the first water level frequency value A to the second water level frequency value B is larger than the preset water level frequency ratio, a common washing program is selected, and when the ratio of the first water level frequency value A to the second water level frequency value B is smaller than or equal to the preset water level frequency ratio, a small-drum washing program is selected.
