Description

Filth blockage prompting method for laundry equipment

Technical Field

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, thereby causing the user experience to be poor.

Although the steps of the control method of the present invention are described herein in a particular order, the order is not limiting and those skilled in the art can perform the steps in a different order without departing from the basic principles of the invention.

Specifically, taking the case when the laundry device is a drum washing machine as an example, in the preferred embodiment, the drum washing machine includes a washing drum and a drainage member communicated with the washing drum, wherein the washing drum includes an outer drum and an inner drum rotatably disposed in the outer drum, the outer drum is used for storing water, the drainage member is used for draining water, a filtering member is disposed in the drainage member, the drained water is filtered by the filtering member and then drained, and the filtering member is detachably mounted so as to be detached by a user for cleaning. It should be noted that the present invention does not limit the specific structure of the drum washing machine, and technicians may set the structure of the washing drum, the drain member and the filter member according to actual use requirements. Such changes in the specific structure may be made without departing from the basic principles of the invention and are intended to be within the scope of the invention.

Further, in the present preferred embodiment, the drum washing machine further comprises a drain flow meter and a controller, which are communicatively connected, wherein the drain flow meter is provided in the drain member, the drain flow meter is activated when the drum washing machine drains water, the drain flow meter can detect the amount of water drained by the drain member per unit time, the controller can acquire detection data of the drain flow meter, and can also control the operation of the drum washing machine; for example, the method includes controlling display content of a display screen of the drum washing machine, controlling lighting color of an indicator light of the drum washing machine, and controlling the drum washing machine to send a prompt to a corresponding mobile client through a network.

It should be noted that the present invention does not limit the specific type and the installation position of the drainage flow meter at all, and a technician may set the drainage flow meter according to the actual use requirement as long as the drainage amount of the drainage member in unit time can be obtained.

In addition, it should be noted that the present invention does not limit the specific structure and model of the controller, and the controller may be the original controller of the drum washing machine, or may be a controller separately provided for executing the filth blockage prompting method of the present invention.

Referring first to fig. 1, a flow chart of main steps of the filth blockage warning method of the present invention is shown. As shown in fig. 1, based on the drum washing machine described in the above preferred embodiment, the filth blockage prompting method of the present invention mainly includes the following steps:

s1: acquiring the water discharge amount of a water discharge component in unit time within a preset time length after the drum washing machine starts water discharge;

s2: selectively signaling cleaning of the filter member according to the amount of water discharged by the water discharge member per unit time.

In step S1, the controller can obtain the water discharge amount of the water discharge member per unit time through the water discharge flow meter within the preset time period after the water discharge of the drum washing machine is started, so as to effectively judge the dirty and blocked condition of the filter member. It will be appreciated that the power of the drain pump of the drum washing machine is generally constant, and therefore in case the water volume in the washing tub is sufficient and the filter member is not dirty, the water discharge per unit time of the drain member should be constant, in which case the water discharge is defined as the standard water discharge in the present invention and can be measured in a laboratory before leaving the factory. It should be noted that, the specific value of the preset duration is not limited, and a technician can set the value according to the actual use requirement, as long as the water discharge amount of the drainage member is not influenced by irrelevant factors. In addition, the time for acquiring the water discharge amount of the water discharge component in unit time is specially selected within the preset time after the drum washing machine starts to discharge water, so that the accuracy of parameters is effectively ensured, and the accuracy of a judgment result is further effectively ensured. In addition, it should be noted that the present invention does not limit the specific stage of the drainage process, and the skilled person can set the drainage process according to the actual use requirement, for example, the drainage process may be a drainage process in a washing stage, a drainage process in a rinsing stage, a drainage process in a self-cleaning stage, and the like, which are not restrictive.

Next, in step S2, the controller can selectively signal cleaning of the filtering member according to the amount of water discharged by the water discharging member per unit time. It should be noted that, the specific manner of determining whether the filtering member is dirty or not according to the water discharge amount of the drainage member in unit time is not limited in any way, and a technician may set the method according to actual use requirements, for example, the method may be determined according to a numerical range of the water discharge amount of the drainage member in unit time, or according to a comparison result between the water discharge amount of the drainage member in unit time and a standard water discharge amount; in addition, the invention does not limit the specific way of the signal for cleaning the filtering component sent by the drum washing machine, and technicians can set the way according to actual use requirements, for example, the prompt can be carried out through a display screen of the drum washing machine, an indicator light of the drum washing machine, or a mobile terminal connected with the drum washing machine.

Referring next to fig. 2, a flowchart of the detailed steps of the preferred embodiment of the filth blockage warning method 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: acquiring the water discharge amount of a water discharge component in unit time within a preset time length after the drum washing machine starts water discharge;

s102: calculating a difference between the standard displacement and a displacement of the drainage member per unit time;

s103: judging whether the difference value is larger than a first preset water discharge amount or not; if not, executing step S104; if yes, executing step S105;

s104: no signal to clean the filter member;

s105: judging whether the difference value is greater than or equal to a second preset water discharge amount or not; if not, executing step S106; if yes, go to step S107;

s106: sending out a reminding signal for cleaning the filtering component;

s107: and sending out a warning signal for cleaning the filtering component.

Further, in step S101, within the preset time period after the drum washing machine starts draining, the controller can obtain the drainage amount of the drainage member in unit time through the drainage flow meter, so as to effectively judge the dirty and blocked condition of the filtering member. It should be noted that, the specific value of the preset duration is not limited, and a technician can set the value according to the actual use requirement, as long as the water discharge amount of the drainage member is not influenced by irrelevant factors. As a preferred setting mode of the preset time duration, the controller can determine the preset time duration according to the current water inflow of the drum washing machine, specifically, the current water inflow of the drum washing machine and the preset time duration are in positive correlation, so as to effectively ensure that the water discharge amount of the drum washing machine is measured when the drain pump is in a full-load working state, thereby effectively avoiding unnecessary measurement errors and ensuring the accuracy of the measurement result.

Next, in step S102, the controller can calculate a difference between the standard water discharge amount and the water discharge amount of the water discharge member per unit time based on the acquisition result of step S101. It should be noted that, the invention does not limit the specific value of the standard displacement, and technicians can set the value according to actual use requirements; further, although the present preferred embodiment uses the difference between the standard displacement and the displacement of the drainage member per unit time to participate in the final determination, this is only a preferred arrangement, and it is obvious that the dirty-blockage indication method may also use the ratio between the displacement of the drainage member per unit time and the standard displacement, or the numerical range of the displacement of the drainage member per unit time, and the like to perform the determination, which is not restrictive.

In step S103, the controller may determine whether a difference between the standard displacement and the displacement of the drainage member per unit time is greater than the first preset displacement so as to selectively signal cleaning of the filtering member according to a comparison result between the difference between the standard displacement and the displacement of the drainage member per unit time and the first preset displacement. It should be noted that, the specific value of the first preset displacement is not limited, and a technician can set the value according to actual use requirements; as a preferable value, the first preset displacement is one fifteenth of the standard displacement, for example, the standard displacement is 30 liters per minute, and the first preset displacement is 2 liters per minute.

If the difference between the standard water discharge amount and the water discharge amount of the water discharge member per unit time is less than or equal to the first preset water discharge amount based on the judgment result of the step S103, step S104 is performed, in which the controller controls the drum washing machine not to send a signal for cleaning the filter member, and the drum washing machine operates normally. And if the difference between the standard displacement and the displacement of the drainage member per unit time is greater than the first preset displacement, performing step S105 in which the controller compares the difference between the standard displacement and the displacement of the drainage member per unit time with the second preset displacement to determine whether the difference between the standard displacement and the displacement of the drainage member per unit time is greater than or equal to the second preset displacement, and determines a type of signaling the cleaning of the filter member according to a result of comparing the difference between the standard displacement and the displacement of the drainage member per unit time with the second preset displacement, thereby signaling the cleaning of the filter member according to the determined type of signaling. Based on the setting mode, different types of prompt signals can be correspondingly sent according to the severity of the blockage of the filtering component, so that the blockage condition of the filtering component can be more clearly fed back to a user, the user can autonomously select the time for cleaning the filtering component according to the blockage condition, and the use experience of the user can be effectively considered while the filtering component can be timely cleaned when being blocked. It should be noted that, the specific value of the second preset displacement is not limited, and a technician can set the second preset displacement according to actual use requirements as long as the second preset displacement is greater than the first preset displacement; as a preferable value, the second preset displacement is three tenths of the standard displacement, for example, the standard displacement is 30 liters per minute, and the second preset displacement is 9 liters per minute.

It should be noted that, although in the preferred embodiment, after the difference between the standard displacement and the displacement of the drainage member per unit time is determined to be greater than the first preset displacement, the type of the signal for cleaning the filter member needs to be determined according to the comparison result between the standard displacement and the displacement of the drainage member per unit time and the second preset displacement, this is only a preferred embodiment, and a technician may be configured to directly signal cleaning of the filter member without distinguishing the type of the signal when the difference between the standard displacement and the displacement of the drainage member per unit time is determined to be greater than the first preset displacement.

Finally, based on the determination result of step S105, if the controller determines that the difference between the standard displacement and the displacement of the drainage member per unit time is greater than the first preset displacement and less than the second preset displacement, it indicates that the filter member has been clogged, in which case step S106 is executed, i.e., a warning signal for cleaning the filter member is issued. And if the controller determines that the difference between the standard discharge amount and the discharge amount of the water discharging member per unit time is greater than or equal to the second preset discharge amount, it indicates that the filter member has been severely clogged, in which case, step S107 is performed, in which a warning signal for cleaning the filter member is issued. As a preferable setting mode, when the type of the sent signal is a warning signal, the user can independently select the time for cleaning the filtering member, and even if the user does not clean the filtering member, the drum washing machine can still normally operate; when the type of the signal is the warning signal, the user needs to clean the filtering component, otherwise, the drum washing machine always sends the warning signal, so that the cleaning effect of the drum washing machine is effectively ensured.

In addition, it should be noted that the present invention does not limit the specific manner of sending the reminding signal and the warning signal to the drum washing machine, for example, in a possible embodiment, the drum washing machine may display corresponding words or corresponding codes through its display screen; for another example, the drum washing machine may further send different types of prompts according to the starting color of the prompting lamp by setting the prompting lamp, where green represents normal operation, orange represents a prompting signal, and red represents a warning signal; 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 apparent that the scope of the present invention is not limited to these specific embodiments, as will be readily understood by those skilled in the art. 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.
