Based on the problem that the existing clothes washing equipment with the internal circulation function is easy to generate extremely large noise when executing an internal circulation program and is at a low water level, the invention provides a control method of the clothes washing equipment with the internal circulation function, aiming at preventing the clothes washing equipment from generating the condition of overlarge noise when executing the internal circulation program and improving the user experience.
Specifically, the laundry washing apparatus of the present invention includes a tub assembly, a first pump member and a second pump member, a water inlet of the first pump member is connected with the tub assembly through a connection pipe, a water outlet of the first pump member is connected with a drain pipe, a water inlet of the second pump member is connected with the connection pipe through a first circulation pipe, and a water outlet of the second pump member is connected with the tub assembly through a second circulation pipe. Wherein, the first pump component can be a drainage pump, the second pump component can be a circulating pump or a suction pump, and the skilled person can flexibly set the specific structure and the selected type of the first pump component and the second pump component in practical application, as long as the drainage of the laundry washing device can be realized through the first pump component, and the water circulation of the laundry washing device can be realized through the second pump component. In addition, the tub assembly includes a washing tub for receiving laundry, and of course, in a drum washing machine or a drum washer dryer, the tub assembly further includes a window gasket and the like, and in a pulsator washing machine, the tub assembly further includes a balancing ring and the like. In the present invention, the water level in the tub assembly may be detected by providing a water level sensor on or in the tub assembly.
It should be noted that, in the present invention, the laundry washing device may be a drum washing machine, a pulsator washing machine or a drum washing and drying machine, and such changes of application objects do not depart from the technical solution of the present invention, and should be limited within the protection scope of the present invention.
As shown in figure 1, firstly, taking the clothes washing equipment as an example of a drum washing machine, the drum washing machine with the internal circulation function of the invention comprises a drum, the drum comprises an outer drum 1 and an inner drum (not shown in the figure) rotatably arranged in the outer drum 1, the drum washing machine also comprises a drainage pump 2 and a circulating pump 3, wherein, a water inlet of the drainage pump 2 is connected with the outer drum 1 through a connecting pipeline 4, a water outlet of the drainage pump 2 is connected with a drainage pipeline 5, a water inlet of the circulating pump 3 is connected with the connecting pipeline 4 through a first circulating pipeline (not shown in the figure), a water outlet of the circulating pump 3 is connected with an annular spraying cavity 7 through a second circulating pipeline 6, the annular spraying cavity 7 is arranged at the joint of a window pad 8 and the outer drum 1 or is directly formed on the window pad 8, when the drum washing machine executes the internal circulation program, the circulating pump 3 is started, at the moment, the water in the, The first circulation pipeline, the circulation pump 3, the second circulation pipeline 6 and the annular spraying cavity 7 are recirculated into the outer barrel 1, and of course, in practical application, the first circulation pipeline, the circulation pump 3, the second circulation pipeline 6 and the annular spraying cavity 7 may be directly recirculated into the outer barrel 1 without passing through the annular spraying cavity 7 (at this time, the second circulation pipeline 6 may be directly connected with the outer barrel 1). Under normal conditions, the drainage pump 2 is in a closed state (at this time, the drainage pump 2 does not drain water but cannot block the outside air), under the action of the internal circulation, the water level in the outer tub 1 may be at a relatively low water level, at this time, the circulation pump 3 may cause the outside air to enter the circulation pump 3 from the drainage pipeline 5 due to the suction action, which causes a great noise, because the water level in the drainage pipeline 5 may also be relatively low when circulating in the drum washing machine, and therefore, as shown in fig. 2, the control method of the present invention includes: acquiring the water level in the outer drum during the internal circulation program of the drum washing machine; the drain pump is selectively activated according to the water level in the outer tub.
Similar to the drum washing machine, the control method of the present invention can obviously be applied to a pulsator washing machine, specifically, the pulsator washing machine comprises a washing tub including an outer tub and an inner tub rotatably disposed in the outer tub, a drain pump and a circulation pump, wherein a water inlet of the drain pump is connected with the outer tub through a connection pipeline, a water outlet of the drain pump is connected with a drain pipeline, a water inlet of the circulation pump is connected with the connection pipeline through a first circulation pipeline, and a water outlet of the circulation pump is connected with an annular spraying cavity through a second circulation pipeline, wherein the annular spraying cavity is disposed on the inner tub, the outer tub, between the inner tub and the outer tub or on a balance ring, when the pulsator washing machine executes an internal circulation program, the circulation pump is turned on, and at this time, water in the outer tub passes through the connection pipeline, the first circulation pipeline, the, The second circulation pipeline and the annular spraying cavity are recycled into the outer barrel, and certainly, in practical application, the second circulation pipeline and the annular spraying cavity can also be directly recycled into the outer barrel without passing through the annular spraying cavity (at this time, the second circulation pipeline can be directly connected with the outer barrel). Under normal conditions, the drainage pump is in a closed state (at this time, the drainage pump does not drain water but cannot block outside air), under the action of the internal circulation, the water level in the outer barrel may be at a relatively low water level, at this time, the circulation pump may cause outside air to enter the circulation pump from the drainage pipeline due to the suction action, so that great noise occurs, because the water level in the drainage pipeline is also relatively low when the circulation is performed in the pulsator washing machine, therefore, for the pulsator washing machine, the control method of the invention comprises the following steps: acquiring the water level in the outer barrel in the process of executing the inner circulation program of the pulsator washing machine; the drain pump is selectively activated according to a water level in the outer tub.
In practical applications, the control method of the present invention can also be applied to other clothes washing apparatuses with an internal circulation function, such as a washing and drying all-in-one machine, which will not be described herein again, and the following only takes a drum washing machine as an example to further illustrate the preferred embodiments of the present invention.
Specifically, the aforementioned step of "selectively activating the drain pump according to the water level in the outer tub" includes: comparing the water level in the outer cylinder with a preset water level; and selectively starting the drainage pump according to the comparison result. The water level in the outer barrel can be directly compared with a preset water level, or the absolute value of the difference value between the water level in the outer barrel and the preset water level is compared with another preset value, or the ratio of the water level in the outer barrel to the preset water level is compared with another preset value, or other parameters such as time parameters and the like are introduced while the water level is compared, and a technical worker in the field can flexibly set the mode of comparing the water level in the outer barrel with the preset water level in practical application, so long as the water level in the outer barrel is judged whether to start the drainage pump or not based on the comparison result. In addition, the preset water level may be a test value obtained through experiments by a person skilled in the art, or may also be an empirical value obtained from experience, and the person skilled in the art may flexibly set the specific water level value of the preset water level in practical applications.
Example one
As shown in fig. 3, the step of "selectively activating the drain pump according to the comparison result" includes: if the water level in the outer cylinder is less than or equal to the preset water level, starting the drainage pump; and if the water level in the outer barrel is higher than the preset water level, not starting the drainage pump. That is to say, when the water level in the outer tub is less than or equal to the preset water level, the drum washing machine has the risk that the outside air enters the circulating pump through the drainage pipeline and generates noise when executing the internal circulation program, the drainage pump should be started at this moment, and the disturbance effect through the drainage pump makes the drainage pipeline have a higher water level, so that the outside air cannot enter the drainage pipeline, and the air cannot reach the circulating pump and generate noise. And when the water level in the outer barrel is greater than the preset water level, the water level in the outer barrel is enough, even if the drum washing machine executes an internal circulation program, the water level in the drainage pipeline cannot be too low, the external air cannot flow into the circulation pump through the drainage pipeline, and therefore the drainage pump does not need to be started.
Example two
The step of selectively activating the drain pump according to the comparison result includes: if the water level in the outer cylinder is less than or equal to the preset water level and lasts for the preset time, starting the drainage pump; if the water level in the outer cylinder is less than or equal to the preset water level but does not last for the preset time, not starting the drainage pump; and if the water level in the outer barrel is higher than the preset water level, not starting the drainage pump. That is, when the water level in the outer tub is less than or equal to the preset water level, the water level may be caused by the fluctuation of the water in the outer tub, and therefore, a time determination condition is introduced, that is, when the water level in the outer tub is less than or equal to the preset water level and lasts for the preset time, it is indicated that the water level in the outer tub is very low at this time, the drum washing machine has a risk that the external air enters the circulation pump from the drain line to generate noise when executing the internal circulation program, the drain pump should be started, and the drain line has a relatively high water level due to the disturbance of the drain pump, so that the external air cannot enter the drain line, and the air does not reach the circulation pump to generate noise. And when the water level in the outer tub is less than or equal to the preset water level but does not last for the preset time, the water level in the outer tub is low at this time due to the fluctuation of the water, and the drainage pump is not started at this time. And when the water level in the outer barrel is greater than the preset water level, the water level in the outer barrel is enough, even if the drum washing machine executes an internal circulation program, the water level in the drainage pipeline cannot be too low, the external air cannot flow into the circulation pump through the drainage pipeline, and therefore the drainage pump does not need to be started.
In the first and second embodiments, if the drain pump is started, the operation speed can be set arbitrarily, i.e. normal drainage can be performed, high-speed drainage can be performed, or low-speed drainage can be performed, and in a preferred case, as shown in fig. 3, the control method of the present invention further includes, at the same time as or after the step of "starting the drain pump": the drain pump is operated at a low speed. That is, the drain pump may be operated at a low speed immediately after the start, or may be operated at a low speed after a lapse of time after the start, and the drain pump may slowly drain water, so that the circulation pump may still be operated for a while. It should be noted that the low-speed operation of the drain pump is compared with the normal operation, the normal operation refers to the operation of the drain pump when the drum washing machine executes the drain program, and the low-speed operation of the drain pump is lower than the rotation speed of the drain pump when the drain pump normally drains, specifically 30%, 40%, or 50% of the rotation speed of the drain pump during the normal operation, and the person skilled in the art can flexibly set the rotation speed of the impeller during the low-speed operation of the drain pump in practical application. In addition, the preset time may be 2 seconds, 3 seconds, 5 seconds, or the like, and a person skilled in the art may flexibly set a specific time value of the preset time in practical applications.
An embodiment of the present invention will be described below with reference to the case of a complete washing process of a drum washing machine and the first embodiment.
The washing machine is started to carry out washing and rinsing for a plurality of times, clothes are weighed before washing and rinsing for each time, then water inflow is set, when the water level in the outer barrel reaches a set water level, the circulating pump is started to carry out washing or rinsing (at the moment, the drainage pump is closed), in the washing and rinsing processes, the water level in the outer barrel is detected in real time, once the water level is smaller than or equal to the preset water level, the drainage pump is started and runs at a low speed, and after the last rinsing is finished, subsequent dewatering and drainage operations are continuously carried out.
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.
