Wherein, the washing machine can be a drum washing machine and a pulsator washing machine; the washing and drying integrated machine can be a drum-type washing and drying integrated machine and a pulsator-type washing and drying integrated machine.

Based on the technical problems in the background art, the invention provides a water inlet fault judging method for a washing machine, which aims to accurately judge whether a drain valve is faulty or whether the washing machine leaks according to the judging result of whether the water level reaches a preset water level threshold value, so that the water inlet fault type can be accurately prompted for a user, the user does not need to find a specification one by one for investigation, and the use experience of the user is improved.
Referring to fig. 1 and 2, fig. 1 is a flowchart of a water inlet failure judging method of the present invention; fig. 2 is a flow chart of a water inlet failure determination method according to an embodiment of the present invention. The washing machine of the invention comprises a drain valve and a controller, wherein the controller can control the opening and closing states of the drain valve, and when the drain valve is in the opening state, the washing machine drains water; when the drain valve is in a closed state, the washing machine does not drain. The controller may be any type of controller in physical form, such as a programmable controller, a combinational logic controller, or the like.
As shown in fig. 1, the water inlet failure judging method of the present invention includes the following steps:
s100, after the washing machine performs water inlet operation for a preset time, acquiring the water level of the washing machine;
s200, judging whether the water level reaches a preset water level threshold value or not;
s300, judging whether the drain valve fails or whether the washing machine leaks according to the judging result of whether the water level reaches the preset water level threshold value.
Preferably, the preset water level threshold value can be, but is not limited to, a water level set by a user or a water level recommended by the washing machine, wherein the water level selected by the user can be, but is not limited to, a water level set by the user according to the material, type, color, dirt degree and other information of the clothes before each operation of the washing machine; the recommended water level of the washing machine may be, but is not limited to, a water level recommended by the washing machine according to the material, type, color, dirt level, etc. of the laundry before each operation of the washing machine.
In a preferred embodiment, the washing machine further comprises a water inlet valve, the controller is capable of controlling an open and closed state of the water inlet valve, and the washing machine does not feed water when the water inlet valve is in a closed state; when the water inlet valve is in an open state, the washing machine is fed with water.
Before the step of "obtaining the water level of the washing machine" in step S100, the water inlet failure determination method further includes:
s010, acquiring the flow of the water inlet valve;
s020, respectively comparing the flow with a first preset flow threshold value and a second preset flow threshold value, wherein the first preset flow threshold value is smaller than the second preset flow threshold value;
s030, if the flow is greater than or equal to a second preset flow threshold, executing the operation of acquiring the water level of the washing machine;
s040, if the flow is larger than a first preset flow threshold but smaller than a second preset flow threshold, the operation of acquiring the water level of the washing machine is not executed, and the water inlet valve is blocked or the water pressure of an external water source is judged to be lower than a preset pressure threshold;
s050, if the flow is less than or equal to a first preset flow threshold, not performing an operation of acquiring the water level of the washing machine, and determining that the water inlet valve is not opened.
Preferably, the inlet valve may be a water inlet flow valve which may meter its flow directly; or a flowmeter is arranged on the water inlet valve, and the flow of the water inlet valve is measured through the flowmeter.
In step S020, the flow rate is compared with the first preset flow rate threshold value and the second preset flow rate threshold value, respectively, but it will be appreciated by those skilled in the art that the flow rate can be compared with one, three, four or any preset flow rate threshold values, and the changes do not depart from the principle and scope of the present invention.
In step S030, if the flow is greater than or equal to the second preset flow threshold, it is indicated that the flow of the water inlet valve is greater, and is within the normal flow range, so that water can be normally fed, and when water is fed at the flow and no other faults exist in the washing machine, the water level of the washing machine can reach the preset water level threshold by the preset time of water feeding of the washing machine, and in order to determine whether other faults exist in the washing machine, after the preset time of water feeding of the washing machine, an operation of obtaining the water level of the washing machine is performed, so that whether the water outlet valve faults exist in the washing machine or other faults such as water leakage of the washing machine are determined according to the water level of the washing machine, and user experience is improved.
Wherein, under the condition that the preset water level threshold value is determined, the preset time is inversely related to the flow of the water inlet valve, namely, the preset time is reduced along with the increase of the flow of the water inlet valve; or, the preset time can also be the time from the water inlet of the washing machine to different preset water level thresholds by taking the second preset flow threshold as a flow reference, and the preset time is also determined after the preset water level threshold is determined; alternatively, the predetermined time is a fixed value, such as the longest time for the water to enter the washing machine to reach the preset water level threshold, or a time obtained by a person skilled in the art according to experiments under specific working conditions, or a time obtained according to experience, whichever is taken, as long as the requirement of whether or not the operation of obtaining the water level of the washing machine is performed, which is determined by the predetermined time, is satisfied.
In step S040, if the flow is greater than the first preset flow threshold but less than the second preset flow threshold, which indicates that the flow of the water inlet valve is smaller and not in the normal flow range, in the case of water inlet at this flow, even if the washing machine performs the water inlet operation according to the maximum time from the set water inlet to the preset water level threshold, the washing machine cannot enter the preset water level threshold, even if the water level of the washing machine is obtained, it cannot be determined whether the drain valve fails or whether the washing machine leaks according to the water level of the washing machine, and the operation of obtaining the water level of the washing machine is not performed.
Further, when the water inlet valve is blocked, the water inlet valve is not smooth and cannot normally inlet water, so that the flow of the water inlet valve is smaller; or when the water pressure of the external water source is lower than the preset pressure threshold value, the water pressure of the external water source is insufficient, and the pressure requirement for enabling the water inlet valve to normally inlet water cannot be met, so that the flow of the water inlet valve is smaller. Thus, it may be determined that the type of fault that results in the flow of the inlet valve being small is a blocked inlet valve or the water pressure of the external water source being below a preset pressure threshold.
The preset pressure threshold is the minimum pressure of the external water source capable of enabling the water inlet valve to normally inlet water, even if the flow of the water inlet valve is equal to the pressure of the second preset flow threshold, or the pressure obtained by a person skilled in the art according to experiments under specific working conditions or the pressure obtained according to experience, and the person skilled in the art can flexibly adjust and set the preset pressure threshold in practical application.
In step S050, if the flow is less than or equal to the first preset flow threshold, it is indicated that the flow of the water inlet valve is very small or no flow, for example, the flow of the water inlet valve is 0L/min, no water is fed, and in the case of water feeding at the flow, the washing machine cannot feed water to the preset water level threshold no matter how long the water is fed, and even if the water level of the washing machine is obtained, it cannot be determined whether the drain valve is faulty or whether the washing machine leaks according to the water level of the washing machine, and then the operation of obtaining the water level of the washing machine is not performed.
Further, taking the case that the flow rate of the water inlet valve is 0L/min as an example, either because the water inlet valve is not opened or because water is stopped, a user will not use the washing machine to wash clothes under the condition of water stopping generally, and the condition of water stopping can be eliminated first, and under the condition of no water stopping, the failure type that the flow rate of the water inlet valve is 0L/min can be judged to be that the water inlet valve is not opened, namely, the failure type that the flow rate is less than or equal to the first preset flow rate threshold is judged to be that the water inlet valve is not opened.
In step S050, the flow rate of the water inlet valve is 0L/min, which is merely exemplary, but not limiting, and those skilled in the art may flexibly adjust and set the flow rate of the water inlet valve in practical applications, for example, 0.01L/min, 0.005L/min, etc.
In addition, in the above process, by setting the first preset flow threshold and the second preset flow threshold, a conclusion is given as to whether to execute the operation of acquiring the water level of the washing machine, and whether to determine the type of water inlet failure that the water inlet valve of the washing machine is not opened, the water inlet valve is blocked, and the water pressure of the external water source is lower than the preset pressure threshold. The first preset flow threshold may be a minimum value for determining that the flow of the water inlet valve is smaller, for example, 0.02L/min, the second preset flow threshold may be a maximum value for determining that the flow of the water inlet valve is smaller, for example, 10L/min, and the first preset flow threshold and the second preset flow threshold may also be flows obtained by a person skilled in the art according to experiments under specific working conditions, or empirically obtained flows, regardless of the flow, as long as the requirements of whether the operation of acquiring the water level of the washing machine, which is determined by the first preset flow threshold and the second preset flow threshold, is performed, and the type of water inlet fault, which determines that the water inlet valve of the washing machine is not opened, the water inlet valve is blocked, and the water pressure of the external water source is lower than the preset pressure threshold, are satisfied.
In the above process, the steps S030 to S050 are not sequential, and are parallel, and only the flow of the inlet valve is related to the comparison result of the first preset flow threshold and the second preset flow threshold, and the corresponding steps are executed according to different comparison results.
Further, the washing machine further includes an outer tub, a sensing passage communicating with the outer tub, and a water level sensor provided in the sensing passage, and the water level in the outer tub is sensed by the water level sensor in step S100. Wherein, the water level sensor can be a pressure sensor, an infrared sensor and the like; the detection channel can also be a hose communicated with the outer barrel or a condensation pipeline communicated with the outer barrel, and no matter what structure is adopted, the detection channel can accurately detect the water level in the outer barrel. It should be noted that the method for detecting the water level should not limit the present invention. Although the "tub" is used, it is not limited to the pulsator washing machine, but may be a drum washing machine.
In a preferred embodiment, in step S300, the step of determining whether the drain valve is faulty or whether the washing machine leaks according to the determination result of whether the water level reaches the preset water level threshold value specifically includes:
s310, judging whether the washing machine is draining or not if the water level does not reach a preset water level threshold;
s320, judging whether the drain valve fails or whether the washing machine leaks according to the judging result of whether the washing machine is draining;
s330, if the water level reaches a preset water level threshold, judging that the washing machine has no water inlet failure.
In step S310, the flow rate of the drain valve may be obtained, and whether the washing machine is draining is determined by the flow rate of the drain valve, and when the flow rate of the drain valve is greater than the set flow rate, it is determined that the washing machine is draining; when the flow rate of the drain valve is less than or equal to the set flow rate, the washing machine is judged to be not drained, wherein the set flow rate is the minimum flow rate for judging that the drain valve is draining, or the flow rate determined by the person skilled in the art according to experience or experiments, and no matter what flow rate is adopted, the requirement of whether the washing machine is draining can be judged. Of course, the method for judging whether the washing machine is draining is not limited to the above-mentioned method, and whether the washing machine is draining can be judged by detecting whether the water flow passes through the drain pipe of the washing machine, no matter what way is adopted to judge whether the washing machine is draining, the specific implementation method corresponding to any way should not limit the invention.
Preferably, the drain valve may be a water inlet flow valve which may meter its flow directly; or a flowmeter is arranged on the drainage valve, and the flow of the drainage valve is measured through the flowmeter.
In step S320, since the current flow of the water inlet valve is greater than or equal to the second preset flow threshold, if the washing machine does not have other faults when water is being fed at the current flow, the water level of the washing machine can reach the preset water level threshold by the preset time, but the water level does not reach the preset water level threshold at this time, which indicates that the washing machine has water-feeding faults, that is possibly caused by water-feeding and water-discharging of the washing machine by the water-discharging valve fault of the washing machine, and that is possibly caused by water-discharging of the washing machine, in order to determine the water-feeding fault type of the washing machine, whether the washing machine is draining is judged, and the water-feeding fault type of the washing machine, that is, the water-discharging valve fault or the water-discharging of the washing machine is accurately judged according to the judging result of whether the washing machine is draining is accurately, so that the water-feeding fault type of the user can be accurately judged, the user does not need to find the instruction to check one by one, and the use experience of the user is further improved.
In step S330, if the water level reaches the preset water level threshold, that is, the washing machine is fed with water at the current flow rate of the water inlet valve for a predetermined time, so that the water level of the washing machine reaches the preset water level threshold, wherein the current flow rate of the water inlet valve is greater than or equal to the second preset flow rate threshold, which indicates that the water inlet valve of the washing machine is not blocked and can normally feed water, and the water inlet flow rate is within the normal flow range, the water outlet valve of the washing machine can be normally closed, the situation that water is fed while water is discharged is not existed, and the situation that water is not leaked is also avoided, the washing machine is judged to be fed normally, no water inlet fault is caused, the situation of misjudgment under the situation that the washing machine is not faulty is avoided, and the use experience of a user is further improved.
It should be noted that, in the above process, the step S310 and the step S330 are not in sequence, and are parallel, and only related to the determination result of whether the water level reaches the preset water level threshold, and the corresponding steps are executed according to different determination results.
Preferably, in step S320, the step of "judging whether the drain valve is malfunctioning or whether the washing machine leaks according to the judgment result of whether the washing machine is draining" specifically includes:
s321, if the washing machine is draining, judging that the drain valve is faulty;
s322, if the washing machine has no water drainage, judging that the washing machine leaks water.
In step S331, if the washing machine is draining, it is indicated that the washing machine is draining while water is being fed, so that the water level of the washing machine does not reach the preset water level threshold after the washing machine is fed for a predetermined time, and since the controller controls the drain valve to be closed during the water feeding operation of the washing machine, the washing machine should not drain water, and the draining condition occurring at this time should be caused by a malfunction of the drain valve, for example, the drain valve is blocked by a foreign material or the drain valve is damaged, and the drain valve cannot be normally closed, and the malfunction of the drain valve is determined.
In step S332, if the washing machine is not draining, i.e. the washing machine is only water-in and not draining, but the water level of the washing machine does not reach the preset water level threshold after the washing machine is water-in for a predetermined time, which indicates that the washing machine has water leakage, it is determined that the washing machine leaks.
In the above process, the steps S321 and S322 are not sequential, and are parallel, and only the determination result of whether the washing machine is draining is relevant, and the corresponding steps may be executed according to different determination results.
In a preferred embodiment, after step S300 "determine whether the drain valve is faulty or whether the washing machine leaks according to the determination result of whether the water level reaches the preset water level threshold", the water inlet fault determining method further includes:
s400, selectively sending prompt information according to the judging result of whether the drain valve is faulty or whether the washing machine leaks.
Preferably, in step S400, the step of selectively transmitting the prompt message according to the result of judging whether the drain valve is failed or whether the washing machine leaks, specifically includes:
s410, under the condition of judging the malfunction of the drain valve, sending prompt information of the malfunction of the drain valve;
s420, under the condition that the water leakage of the washing machine is judged, sending prompt information of the water leakage of the washing machine;
s430, under the condition that the washing machine is judged to have no water inlet fault, no prompt information is sent.
