Description
Technical Field
The invention belongs to the technical field of washing, and particularly relates to a filth blockage prompting method for laundry equipment.
Background
In order to prevent the drain pump and even the sewer from being blocked, the drain member of the existing laundry device is generally provided with a filtering device; taking a drum washing machine as an example, a drainage filter of the existing drum washing machine is usually designed together with a drainage pump, and is shielded by a filter door in the daily use process and hidden, so that many users even do not know that the drainage filter needs to be cleaned when the drum washing machine has no drainage fault. Although the existing part of the drum washing machine is also provided with a filter which can be cleaned automatically, the automatic cleaning effect is not as good as the manual cleaning effect; of course, a small number of users know that the drain filter needs to be cleaned, but because the filter of the drum washing machine is more complex to clean than the filter of the pulsator washing machine and has residual sewage inside, if the user tries to remove the drain filter, the user finds that the inside of the filter is still clean when opening the drain filter and does not need to clean the filter, and the user can easily feel that the user feels whitish labor.
In addition, even though the drum washing machine has not been subjected to drainage failure due to the blockage of the drainage filter, a lot of threads and scraps are still collected in the drainage filter after the drum washing machine operates for dozens of washing cycles, and particularly, the drum washing and drying all-in-one machine is serious; and because most of the drum washing machines adopt an upper drainage design, the gathered thread scraps and dust attached to the thread scraps can be soaked in water for a long time and are easy to mildew and deteriorate or even turn black, and when the drum washing machine performs the next washing degree, the thread scraps can be mixed with washing water again or even partially flow back to a washing drum, so that the drum washing machine is not sanitary and healthy, and the drainage filter is really necessary to be cleaned in time. Meanwhile, the clogging problem of the drain filter also causes the forced extension of the drain time, thereby causing the corresponding extension of the execution time of the whole washing program and further affecting the whole washing efficiency. In addition, when the lint in the drainage filter is gathered too much and even causes the drum washing machine to malfunction, the user often needs to seek a professional maintenance person to go to the door for maintenance, which not only increases the maintenance cost but also affects the normal use of the user, and further causes the user experience to be poor.
Accordingly, there is a need in the art for a new method of providing a filth blockage warning for a laundry device to solve the above problems.

Changes in this specific manner of comparison may be made without departing from the underlying principles of the invention and are intended to be within the scope of the invention.
Referring next to fig. 2, a flowchart detailing the steps of a preferred embodiment of the present invention is shown. As shown in fig. 2, based on the drum washing machine in the above preferred embodiment, the preferred embodiment of the filth blockage prompting method of the present invention specifically includes the following steps:
s101: making the drum washing machine execute a self-cleaning program;
s102: injecting water into the washing drum to a preset water level;
s103: draining the drum washing machine and recording the draining time;
s104: calculating the difference value between the drainage time length and the preset drainage time length, and recording the difference value as a first difference value;
s105: judging whether the first difference value is larger than a preset difference value or not; if not, executing step S106; if yes, go to step S107;
s106: no signal to clean the filter member;
s107: signaling cleaning of the filter member;
s108: sending a control signal to clean the filter member;
s109: calculating a difference value between the first difference value and a preset difference value, and recording the difference value as a second difference value;
s110: determining a mode of sending out a reminding signal for cleaning the filtering component according to the range of the second difference value;
s111: if the second difference is smaller than or equal to the first preset value, a display screen of the laundry device sends out a prompt for cleaning the filtering component;
s112: if the second difference value is larger than the first preset value and smaller than the second preset value, a display screen of the laundry equipment sends a prompt for cleaning the filtering component and controls an indicator lamp of the laundry equipment to flicker;
s113: if the second difference is larger than or equal to the second preset value, the display screen of the laundry device sends out a prompt for cleaning the filtering component and controls a buzzer of the laundry device to be started.
In step S101, the controller controls the drum washing machine to perform a self-cleaning program; it should be noted that, the invention does not limit the specific steps executed when the drum washing machine executes the self-cleaning program, and technicians can set the self-cleaning program according to actual use requirements as long as the drum washing machine can self-clean the washing drum; for example, the controller may control the inner barrel to perform the forward and reverse rotation for multiple times to achieve the self-cleaning effect.
In step S102, the controller controls the water inlet device of the drum washing machine to be opened to fill water into the washing tub until the preset water level is reached, although the present invention does not limit the specific water filling manner, and the user may fill water into the washing tub by himself or herself in other manners, which is not limiting. In addition, it should be noted that, the invention does not limit the specific value of the preset water level, and the technical personnel can set the value according to the actual use requirement; preferably, the preset water level is selected according to a water level selection mode of a self-cleaning program of the drum washing machine.
Next, in step S103, the controller controls a drainage member of the drum washing machine to communicate and records a drainage duration, and during the drainage process, the water in the washing tub is filtered by the filter member and drained by the drainage member; it should be noted that the specific manner of acquiring the draining time period is not limited in the present invention, and the technician may set the draining time period according to the actual use requirement, for example, the draining time period may be acquired to calculate, or the water storage condition in the washing tub may be detected to calculate.
Executing step S104 based on the acquisition result of step S103, wherein the controller calculates a difference value between the drainage time length and the preset drainage time length, and records the difference value as a first difference value; it is understood that the larger the first difference value is, the more serious the clogging of the filter member is, and the controller may judge the clogging degree of the filter member according to the magnitude of the first difference value. In addition, it should be noted that the present invention does not limit the specific value of the preset draining time, and preferably, the preset draining time is determined by a technician in a clean state of the filtering member.
Next, step S105 is performed, and the controller is capable of determining whether the first difference is greater than the preset difference so as to determine the clogging degree of the filter member, and selectively issuing a cleaning signal based on the clogging degree of the filter member. Specifically, if the controller determines that the first difference is smaller than or equal to the preset difference, the drum washing machine does not send a signal for cleaning the filter member and continues to operate normally; if the controller judges that the first difference is larger than the preset difference, the blockage situation of the filtering component is serious, and in this situation, the drum washing machine sends out a signal for cleaning the filtering component, so that the filtering component can be cleaned in time. It should be noted that, the specific value of the preset difference is not limited, and a technician can set the difference according to actual use requirements, and the filter member needs to be cleaned as long as the first difference is greater than the preset difference; preferably, the preset difference value is determined by the type of the filter member.
In the case where step S107 is performed, i.e., in the case where a signal to clean the filter member is issued, the present preferred embodiment provides two ways of issuing a signal:
the first way is the way corresponding to step S108, that is, the controller can send out a control signal for cleaning the filtering member so as to control the drum washing machine to clean itself; of course, this is not restrictive, and the skilled person may set itself according to the actual use requirements and the specific structure of the drum washing machine, i.e. the method may not include this step. Specifically, when the drum washing machine has an operation of automatically cleaning the filter member, if the controller determines that the first difference is greater than the preset difference, the controller controls the drum washing machine to automatically clean the filter member, so that the cleaning degree of the filter member is effectively ensured, and the drainage speed of the drainage member is effectively ensured.
The second manner is a manner corresponding to step S109 and step S110, that is, if the first difference is greater than the preset difference, the controller controls the drum washing machine to send out a warning signal for cleaning the filter element. Specifically, in step S109, the controller may calculate a difference between the first difference and the preset difference, and record the difference as a second difference, so that the controller may determine that the clogging degree of the filter member exceeds the minimum prompting degree according to the second difference; next, in step S110, the controller can determine a manner of sending a warning signal for cleaning the filtering member according to a range in which the second difference is located, that is, the controller can select different warning manners according to different degrees of clogging of the filtering member, so that a user can clearly know the clogging condition of the filtering member. It should be noted that such prompt is only for reminding the user to clean the filtering component in time, and does not affect the normal use of the drum washing machine.
Further, in the preferred embodiment, the determining of the manner of sending the reminding signal of cleaning the filtering member according to the range of the second difference specifically includes the following three conditions:
the first is the method corresponding to step S111, if the controller determines that the second difference is smaller than or equal to the first preset value, in this case, the blocking degree of the filtering member just reaches the reminding standard, so the controller only controls the display screen of the drum washing machine to send out the reminding of cleaning the filtering member, that is, controls the display screen to display corresponding characters or codes for reminding. It should be noted that, the specific value of the first preset value is not limited in the present invention, and a technician may set the value according to actual use requirements, and as long as the second difference is less than or equal to the first preset value, the filter member just reaches the blockage degree that needs to be cleaned.
The second way is the corresponding way of step S112, if the controller determines that the second difference is greater than the first preset value and smaller than the second preset value, at this time, the blocking degree of the filtering member is relatively serious, so that the controller controls the display screen of the drum washing machine to send a prompt for cleaning the filtering member and controls the indicator light of the drum washing machine to flash, so as to prompt the user to clean the filtering member in time. It should be noted that, the specific value of the second preset value is not limited in the present invention, and a technician may set the specific value according to actual use requirements, and as long as the second difference is greater than the first preset value and less than the second preset value, it indicates that the clogging degree of the filter member is relatively serious; in addition, the present invention does not limit the specific setting condition of the indicator light, and the indicator light may be an original indicator light of the drum washing machine, or may be a separately set indicator light for executing the filth blockage prompting method of the present invention.
The third is a manner corresponding to step S113, if the controller determines that the second difference is greater than or equal to the second preset value, at this time, the blocking degree of the filtering member is very serious, so that the controller controls the display screen of the drum washing machine to send a prompt for cleaning the filtering member and controls the buzzer of the drum washing machine to turn on, so as to send a strong cleaning prompt to the user.
Finally, it should be noted that the above prompting manner is only a preferred setting manner, and a technician may also set the setting manner according to actual use requirements, for example, the drum washing machine may also send different reminders only by the flashing color of the prompting lamp, such as green for no blockage, yellow for light blockage, orange for medium blockage, red for heavy blockage, and the like; moreover, for the intelligent washing machine, the controller can remind the user through voice or an APP client, and can even send the specific blocking condition and the specific cleaning mode of the filter component to the user, so that the user experience is further improved.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
