Further, the diversion cavity is arranged between the water containing barrel and the washing barrel, and a through hole for the water inlet main path to penetrate is arranged on the barrel wall of the water containing barrel.
By adopting the technical scheme, the invention has the following effects:
because the diversion cavity can buffer the water in the water inlet main way, the buffer water quantity in the diversion cavity can be controlled by controlling the single opening time of the water inlet valve, different buffer water quantities correspond to different water level heights, and in the first water inlet mode, the single opening time ta of the water inlet valve is controlled to be less than or equal to a preset value t1, so that the water level in the diversion cavity exceeds the position of the diversion cavity communicated with the first water inlet branch but is lower than the position of the diversion cavity communicated with the second water inlet branch, and at the moment, the water in the diversion cavity is only supplied to the space between the water bucket and the washing drum through the first water inlet branch; in the second water inlet mode, controlling the single opening time tb of the water inlet valve to be larger than a preset value t2 so that the water level in the diversion cavity exceeds the position where the diversion cavity is communicated with the first water inlet branch and the position where the diversion cavity is communicated with the second water inlet branch, and water in the diversion cavity simultaneously enters the water bucket and the washing drum through the first water inlet branch and the second water inlet branch, so that in order to avoid wetting clothes in the water inlet process, for example, the deodorizing process, the clothes treatment equipment can adopt the first water inlet mode for water inlet; when the requirement on whether clothes are wetted or not in the water inlet process is not met, such as a washing process and a rinsing process, the clothes treatment equipment adopts a first water inlet mode for water inlet and/or a second water inlet mode for water inlet, so that the requirements of different clothes treatment processes can be met, and when the second water inlet mode is adopted for water inlet, water is simultaneously supplied through the first water inlet branch and the second water inlet branch, so that the water inlet time can be effectively shortened, and the use experience of a user is improved.

By the design, the water quantity can be buffered in the diversion cavity, so that the water level can rise to the second water outlet and flow out from the second water outlet in the second water inlet mode.
In the first water inlet mode, the water inlet valve is intermittently opened, the water storage capacity in the diversion cavity when the water level reaches the lowest point of the second water outlet is V, the volume of a cavity in the diversion cavity below the lowest point of the second water outlet is DeltaV, deltaV is more than or equal to 0 and less than or equal to V, and a preset value t1= DeltaV/(Va-Vb).

Or, the laundry treating apparatus further includes a water level sensor for collecting water level data H between the tub and the wash tub, and in the first water intake mode, the water intake valve is closed when the water level data H reaches a preset water level threshold H.

Embodiment 1,
Referring to fig. 1 to 4, the laundry treating apparatus in the present embodiment includes a body including a tub 100, a washing tub 200, a water inlet valve 300, and a water inlet pipe, the washing tub 200 being for holding laundry and being rotatable with respect to the tub 100, the water inlet valve 300 being a solenoid valve, and a control unit provided on the body, the water inlet pipe including a water inlet main path 400, a split flow chamber 500, a first water inlet branch path 600, and a second water inlet branch path 700.

In order to reduce the outer diameter of the tub and reduce the material cost, the diversion cavity 500 in the present embodiment is disposed at the outer side of the tub 100, the wall of the tub is provided with a first mounting hole 110 and a second mounting hole 120, the first water inlet branch 600 penetrates through the first mounting hole 110 and opens between the tub 100 and the washing tub 200, and in order to facilitate the water in the first water inlet branch 600 to be discharged, the water outlet end of the first water inlet branch 600 extends downward and then penetrates through the first mounting hole 110 and continues to extend downward; the second water inlet branch 700 penetrates the second mounting hole 120 and opens into the washing tub 200.
The water inflow control method in the embodiment comprises the following steps:
the first water inlet mode, the control unit controls the single opening time ta of the water inlet valve 300 to be less than or equal to a preset value t1, so that water in the diversion cavity is supplied to the space between the water bucket and the washing drum only through the first water inlet branch; the method comprises the steps of,
in the second water inlet mode, the control unit controls the single opening time tb of the water inlet valve 300 to be greater than the preset value t2 so that water in the split flow chamber is simultaneously supplied to the tub and the wash tub through the first and second water inlet branches.
Because the diversion cavity 500 can buffer the water in the water inlet main 400, the buffer water amount in the diversion cavity 500 can be controlled by controlling the single opening time of the water inlet valve 300, different buffer water amounts correspond to different water level heights, and in the first water inlet mode, the single opening time ta of the water inlet valve 300 is controlled to be less than or equal to a preset value t1, so that the water level in the diversion cavity 500 is higher than the first water outlet 520 and lower than the second water outlet 530, and the water in the diversion cavity 500 is supplied to the space between the water tub 100 and the washing drum 200 only through the first water inlet branch 600; in the second water inlet mode, the single opening time tb of the water inlet valve 300 is controlled to be greater than the preset value t2, so that the water level Gao Dudi in the split flow chamber 500 is divided into two water outlets 530, and the water in the split flow chamber is simultaneously supplied to the tub 100 and the wash tub 200 through the first water inlet branch 600 and the second water inlet branch 700. The clothes treating apparatus in this embodiment includes at least two clothes treating processes requiring water intake, such as washing, rinsing and deodorizing, in which the clothes treating apparatus may adopt a first water intake mode for water intake in order to avoid wetting the clothes during the water intake process; in the washing course and the rinsing course, in order to shorten the water inlet time, the laundry treatment apparatus adopts the second water inlet mode for water inlet, so that the laundry treatment apparatus in this embodiment can provide different water inlet modes according to the requirements of different laundry treatment courses.
Specifically, since the three-way pipe has a limited inner diameter, the water storage capacity of the diversion chamber 500 is small, and in order to meet the water demand in the deodorizing process, the diversion chamber 500 needs to store water and drain water for multiple times, so in the first water inlet mode, the water inlet valve 300 needs to be opened intermittently, and the number of times of opening the water inlet valve 300 is at least two, in order to ensure that the water in the diversion chamber 500 is only discharged through the first water inlet branch 600 during the opening time of the water inlet valve 300, in this embodiment, the preset value t1 needs to be defined: when the water level in the diversion cavity 500 reaches the lowest point of the second water outlet 530, namely, when the water in the diversion cavity 500 cannot be discharged from the second water outlet 530, the maximum water amount which can be stored in the diversion cavity 500 is V, in the first water inlet mode, the water in the diversion cavity is discharged through the first water inlet branch 600 within the time when the water inlet valve 300 is closed, after the closing time of the water inlet valve 300 reaches, the volume of a cavity below the lowest point of the second water outlet in the diversion cavity is DeltaV, deltaV is less than or equal to V, the preset value t1= DeltaV/(Va-Vb), and the single opening time ta of the water inlet valve 300 each time is less than or equal to the preset value t1. In this way, it is ensured that water is prevented from being discharged from the second water outlet 530 during each opening time of the water inlet valve 300.
For ease of understanding, Δv is illustrated with specific numbers in the present embodiment: since the first water outlet 520 is located at the lowest position of the diversion cavity 500, when the machine body is not in use, the water in the diversion cavity 500 is drained, so that in an initial state, the water storage capacity in the diversion cavity 500 is 0, and in the closing time of the water inlet valve 300, the water in the diversion cavity 500 is drained through the first water outlet 520, and if V is 1L, va=0.3L/S, vb=0.1L/S, if the closing time toff of the water inlet valve 300 is long enough, i.e. toff is more than or equal to 10S, the water in the diversion cavity 500 is completely drained after the closing time is over, in this case, before each water inlet, the cavity volume is Δv is always 1L, and at this time, the preset value t1=1/(0.3-0.1) =5S, i.e. each opening time of the water inlet valve 300 is controlled to be no more than 5S.
If a portion of the water is stored in the diversion chamber 500 after the closing time toff of each of the water inlet valves 300 is completed, the Δv varies according to the closing time and the opening time. Specifically, since DeltaV=1L in the initial state, when the first opening time ta1 of the water inlet valve 300 is less than or equal to 5S, if ta 1=5S, the water storage amount in the diversion cavity 500 after the end of the first water inlet is 5 (0.3-0.1) =1L, when the first closing time of the water inlet valve 300 is toff1, in toff1, the water in the diversion cavity is discharged through the first water outlet 520, the water discharge amount is toff1 x 0.1, the residual water storage amount in the diversion cavity 500 is 1-toff1 x 0.1, if toff 1=6S, the water discharge amount is 6 x 0.1=0.6L, when the residual water storage amount in the diversion cavity 500 is 0.4L, and when DeltaV=0.6L, the second opening time ta2 is less than or equal to 0.6/(0.3-0.1), that is ta2 is less than or equal to 3S, if ta 2=2S, the water storage amount in the shunt cavity 500 after the second water inflow is finished is 0.4+2=0.8l, the second closing time of the water inlet valve 300 is toff2, if toff 2=5s, the water drainage amount is 5×0.1=0.5l, at this time, the residual water storage amount in the shunt cavity 500 is 0.8-0.5=0.3L, at this time Δv=1-0.3=0.7l, the third opening time ta3 of the water inlet valve 300 is less than or equal to 0.7/(0.3-0.1), i.e., ta3 is less than or equal to 3.5S, if ta 3=3S, the water storage amount in the shunt cavity 500 after the third water inflow is finished is 0.3+3×0.2=0.9l, the third closing time of the water inlet valve 300 is toff3, if toff 3=9.5s, the water drainage amount is 9.5×0.1=0.95l, at this time ta is 0.1/(0.1.4) and the residual water storage amount in the shunt cavity 500 is 0.1=0.1-0.5l, i.1/(ta 4.4.5S). According to the above calculation method, the value range of the next opening time of the water inlet valve 300 can be obtained by setting the last opening time and the last closing time. As can be seen, the designer needs to set the time for opening the inlet valve each time based on V, va, vb, ta last time, and toff last time, and the specific setting method can be referred to above.
It will be appreciated that in other embodiments of the present invention, if the first water outlet is not provided at the lowest position of the diversion cavity, a portion of water remains in the diversion cavity after the diversion cavity is drained, and the amount of water remaining in the portion is V Stagnation of food The designer needs to set V when setting each opening time of the water inlet valve Stagnation of food In consideration of this, the specific setting value can be adjusted on the basis of the calculation method according to the present embodiment, and the calculation process thereof will be easily understood by those skilled in the art with reference to the calculation method according to the present embodiment, and will not be described in detail herein.
In the second water inlet mode, the control unit controls the single opening time tb of the water inlet valve to be greater than a preset value t2, the preset value t2=v/(Va-Vb), so that when the single opening time tb of the water inlet valve exceeds the preset value t2, the water level in the diversion cavity is higher than the second water outlet 530, so that water in the diversion cavity 500 flows out of the first water outlet 520 and the second water outlet 530 at the same time, and the water yield in the unit time of the second water outlet is Vc, vc is greater than Vb, and the design is such that most of water in the diversion cavity flows out of the second water outlet 530, and most of water enters the washing drum to wet clothes.
Because the wall of the washing drum 200 is provided with the through hole, the water level in the water tub 100 will enter the washing drum 200 through the through hole after being too high, in order to avoid that the water level rises to wet clothes in the deodorizing process, the water level between the water tub 100 and the washing drum 200 needs to be controlled, in the first water inlet mode, when the water level between the water tub and the washing drum is set to reach the preset water level, the required water inlet time threshold is tA, when the accumulated opening time taZ of the water inlet valve reaches the preset water inlet time threshold tA, the control unit closes the water inlet valve 300, wherein taZ =ta1+ta2+ta3+ta4+ … … + taN, and N is a positive integer greater than or equal to 2.
It is to be understood that in other embodiments of the present invention, the laundry treating apparatus further includes a water level sensor for collecting water level data H between the tub and the wash tub, and in the first water inlet mode, the water level sensor transmits the detected water level data H to the control unit, and the control unit closes the water inlet valve when it is judged that the water level data H reaches a preset water level threshold H.
In order to shorten the water intake time during the washing and rinsing processes, the water intake valve 300 is maintained in a normally open state in the second water intake mode. In the washing and rinsing processes, since water wets the laundry in the drum 200 and the required amount of water is greater than the deodorizing process, in order to ensure that the laundry is wetted and the washing and rinsing effects are improved, the water amount in the drum reaches a preset water level, the required water inlet time threshold is tB when the water level in the drum is set to reach the preset water level, and the control unit closes the water inlet valve 300 when tB reaches the water inlet time threshold tB.
It will be appreciated that in other embodiments of the present invention, in the second water intake mode, the water intake valve may be opened intermittently, in which case, when the accumulated opening time tbZ of the water intake valve reaches the preset water intake time threshold tB, the control unit closes the water intake valve 300, where tbZ =tb1+tb2+tb3+tb4+ … … + tbN, and N is a positive integer greater than or equal to 2.
Embodiment II,
Unlike the first embodiment, the water inlet pipe in this embodiment includes a water storage tank, a diversion cavity is formed inside the water storage tank, when the water storage capacity V is sufficiently large, and under the condition that the water consumption in the deodorizing process can be met by primary drainage of the diversion cavity, in the first water inlet mode, the water inlet valve 300 only needs to be opened once, at this time, the opening time tA of the water inlet valve 300 is less than or equal to the preset value t1, and ta=ta, so as to avoid water from entering the washing drum 200.
Third embodiment,
Unlike the first embodiment, the laundry treating apparatus of the present embodiment includes at least one laundry treating process requiring water inflow, for example, a washing process and/or a rinsing process, and the first water inflow mode and the second water inflow mode are sequentially performed in the same laundry treating process, i.e., the washing process includes two water inflow stages, and the two water inflow stages adopt the first water inflow mode and the second water inflow mode, respectively; and/or the rinsing process comprises two water inlet stages, wherein the two water inlet stages adopt a first water inlet mode and a second water inlet mode respectively.
Fourth embodiment,
