DETAILED DESCRIPTION

[0079] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention as detailed in the appended claims.

[0080] Currently, existing twin-drum washing machines cannot steam both laundry processing drums simultaneously during steam care mode, resulting in a long cleaning time and a poor user experience. In the embodiments of the present invention, a split air box is provided so that the two laundry processing drums share a common air duct structure. The split air box distributes drying airflow to either a single or dual drum, and the rotation of the air distributor in the split air box distributes steam to the different laundry processing drums, thus achieving efficient steam care for the twin-drum laundry processing device.

[0081] The following is combined with Figure 1 -Attached Figure 9 The technical solution of this embodiment is described in detail. The following implementation methods and embodiments can be combined with each other unless there is any conflict.

[0082] Example

[0083] like Figures 1-9 As shown, a first aspect of an embodiment of the present invention provides a clothes processing device, comprising:

[0084] The laundry treatment drum comprises a first laundry treatment drum 1 and a second laundry treatment drum 2;

[0085] The drying duct 3 is a drying duct shared by the first laundry processing drum 1 and the second laundry processing drum 2, and can be selectively connected to the first laundry processing drum 1 and / or the second laundry processing drum 2 to form a drying flow path. The drying duct is provided with a drying processing component and a fan;

[0086] The steam generating device 4 is arranged in the drying air duct 3 and provides steam for the first laundry processing drum 1 and / or the second laundry processing drum 2 connected to the drying air duct through the drying air duct.

[0087] The air distribution mechanism includes an air distribution box 5 and an air distribution member 54.

[0088] The air box 5 includes an air inlet 51, a first air outlet 52 and a second air outlet 53. The air inlet 51 of the air box 5 is connected to the air outlet of the drying duct, the first air outlet 52 is connected to the first laundry processing drum 1, and the second air outlet 53 is connected to the second laundry processing drum 2;

[0089] The air distribution member 54 is rotatably arranged inside the air distribution box 5. The air distribution member 54 is designed to change the amount of air flowing out of the first air outlet 52 and the amount of air flowing out of the second air outlet 53 when the air distribution member 54 rotates.

[0090] In the embodiment of the present invention, a dividing air box 5 is provided so that the two clothing processing drums {the first clothing processing drum 1 and the second clothing processing drum 2} share an air duct structure {the drying duct 3}, and the dividing air box 5 is used to realize the single-drum or double-drum drying air flow distribution. The steam generating device 4 is connected to the drying duct 3, and the steam amount of different clothing processing drums is distributed by rotating the air dividing member 54 in the dividing air box 5, thereby realizing the efficient steam care function of the double-drum clothing processing device and shortening the drying and steam care time.

[0091] Specifically, the drying air duct further includes an air duct inlet opposite to the air duct outlet;

[0092] The above-mentioned fan includes a fan air inlet 1, a fan air inlet 2 and a fan air outlet;

[0093] The air outlet of the fan is connected to the air duct inlet of the air distribution box body, the first air outlet of the air distribution box is connected to the first clothes processing drum, the second air outlet is connected to the second clothes processing drum, the first clothes processing drum is connected to the fan inlet 1 of the fan, and the second clothes processing drum is connected to the fan inlet 2 of the fan;

[0094] The fan, the air box and the first laundry processing drum connected in sequence constitute a first drying circulation path of the first laundry processing drum, and the fan, the air direction and the second laundry processing drum connected in sequence constitute a second drying circulation path of the second laundry processing drum.

[0095] That is, the first circulating drying flow path for drying the clothes in the first laundry processing drum and the second circulating drying flow path for drying the clothes in the second laundry processing drum in the embodiment of the present invention share the same drying air duct 3 .

[0096] More specifically, the first clothing processing drum 1 and the second clothing processing drum 2 are distributed up and down, and the drying duct 3 is arranged between the first clothing processing drum 1 and the second clothing processing drum 2; in the embodiment of the present invention, by arranging the drying duct 3 between the two clothing processing drums, the space between the two clothing processing drums can be fully utilized and the overall size of the product can be reduced.

[0097] The clothes processing device further includes a first front air supply duct 6 and a second front air supply duct 7 provided on the front side of the clothes processing device. One end of the first front air supply duct 6 is connected to the front side of the first clothes processing drum 1, and the other end is connected to the first air outlet 52 of the air distribution box 5. One end of the second front air supply duct 7 is connected to the front side of the second clothes processing drum 2, and the other end is connected to the second air outlet 53 of the air distribution box 5.

[0098] The clothing processing device also includes a first rear air supply duct and a second rear air supply duct arranged on the rear side of the clothing processing device. One end of the first rear air supply duct is connected to the rear side of the first clothing processing drum, and the other end is connected to the air inlet 1 of the fan. One end of the second rear air supply duct is connected to the rear side of the second clothing processing drum, and the other end is connected to the air inlet 2 of the fan.

[0099] In the embodiment of the present invention, the two clothing processing drums are distributed up and down, and the drying duct 3 is set by making full use of the gap between the two clothing processing drums, and an air distribution box 5 is set between the two clothing processing drums, which is connected to the drying duct 3 and the clothing processing drum respectively. Without increasing the overall size of the clothing processing device, single-drum or double-drum air flow distribution is achieved. The rotation of the air distribution part 54 in the air distribution box 5 can achieve the distribution of steam amount in different clothing processing drums, thereby realizing the efficient steam care function of the double-drum clothing processing device and shortening the steam care time.

[0100] Further, such as Figure 1 and Figure 2 As shown, the steam generating device is arranged between the air distribution mechanism and the fan;

[0101] The steam generating device 4 is placed in the drying air duct 3 or outside the drying air duct 3;

[0102] When the steam generating device 4 is placed outside the drying air duct 3 , the air outlet of the steam generating device 4 is connected to an air outlet pipe, and the air outlet end of the air outlet pipe is connected to the drying air duct 3 .

[0103] In any of the above embodiments, Figure 1 and Figure 2 As shown, the fan 8 is a variable frequency fan;

[0104] The laundry treatment device further comprises:

[0105] a temperature sensor, the temperature sensor being used to obtain the temperature of at least one of the first laundry processing tub 1 and the second laundry processing tub 2;

[0106] The controller is used to control the rotation speed of the fan 8 according to the temperature value of at least one of the first laundry processing tub 1 and the second laundry processing tub 2.

[0107] In the embodiment of the present invention, by setting the fan 8 as a variable frequency fan and combining it with the setting of a temperature sensor, the speed of the fan 8 can be controlled according to the temperature value in the clothing treatment drum, thereby improving the steam care effect on the clothes in the clothing treatment drum.

[0108] Specifically, when the steam temperature {i.e., the temperature inside the drum} of at least one of the first laundry processing drum 1 and the second laundry processing drum 2 reaches a first preset temperature value, the fan 8 is controlled to start at a low speed, and the fan 8 is increased to assist in accelerating the steam flow rate, so that the load absorbs water quickly and the steam utilization rate is improved, thereby achieving the effect of improving steam care efficiency and improving steam utilization rate.

[0109] It is worth noting that when the steam temperature of at least one of the first clothing processing drum 1 and the second clothing processing drum 2 reaches the first preset temperature value, there is almost no pressure difference between the clothing processing drum and the outside world, and the steam cannot flow quickly and directional in the air duct. Turning on the fan can make the air in the air duct flow quickly into the drum, thereby providing the pressure difference required for steam flow and accelerating the steam flow speed; because the steam is easily blown away by excessive air volume, the fan 8 is selected to be turned on at a low speed.

[0110] More specifically, when the steam temperature in the clothes processing drum drops to a second preset temperature value, the fan 8 is controlled to turn off, wherein the first preset temperature value is set to be slightly lower than the evaporation temperature of water at normal pressure, and the second preset temperature value is set to be lower than the first preset temperature value to avoid affecting the steam heating efficiency.

[0111] It is worth noting that when the steam temperature in the laundry processing drum reaches the second preset temperature value, the steam temperature in the laundry processing drum is low and the amount of steam generated is very small, and it is necessary to continue to heat the water in the steam box to generate more steam.

[0112] In any of the above embodiments, the laundry processing device further includes:

[0113] A current sampler, the current sampler is used to collect the output current value of the first motor and the output current value of the second motor;

[0114] a controller, the controller being configured to control the rotation of the air distribution member according to the output current value of the first motor and the output current value of the second motor;

[0115] The first motor is used to drive the first laundry processing tub 1 to rotate, and the second motor is used to drive the second laundry processing tub 2 to rotate.

[0116] In the embodiment of the present invention, by obtaining the current value of the motor, the load amount in the two laundry processing drums can be obtained, and the air flow entering each laundry processing drum is controlled according to the load amount in the two laundry processing drums.

[0117] It should be noted that a circular chamber is formed inside the air distribution box 5, the air distribution member 54 is preferably an air distribution paddle rotatably arranged inside the circular chamber of the air distribution box 5, and the steam generating device 4 is a steam generating device.

[0118] Specifically, such as Figure 3-Figure 6 As shown, the air distribution member 54 includes a first end portion 541 and a second end portion 542 formed on opposite sides of the air distribution member's rotation axis. The second end portion 542 extends into the drying air duct 3. The first end portion 541 can slide along the inner wall of the air distribution box 5 and remain in contact with it when the air distribution member 54 is driven to rotate.

[0119] When the air distribution member 54 is driven to rotate, the first end portion 541 of the air distribution member 54 rotates along the inner wall of the air distribution box 5 , and the second end portion 542 of the air distribution member 54 rotates in the drying air duct 3 .

[0120] like Figure 3-Figure 5 As shown, when the air distribution member 54 rotates in the air distribution box 5, the air intake amount entering the first clothing processing drum 1 and the air intake amount entering the second clothing processing drum 2 can be changed due to the change in the position of the second end 542 of the air distribution member 54.

[0121] Specifically, the upper end of the air distribution member 54 and the drying air duct 3 form a first channel connected to the first laundry processing drum, and the lower end of the air distribution member 54 and the drying air duct 3 form a second channel connected to the second laundry processing drum.

[0122] like Figure 3 As shown, when the second end 542 of the air distribution member 54 rotates to Figure 3 When the air intake area of ​​the first channel is smaller than the air intake area of ​​the second channel, the air intake volume of the first laundry treatment tub 1 is smaller than the air intake volume of the second laundry treatment tub 2.

[0123] like Figure 4 As shown, when the second end 542 of the air distribution member 54 rotates to Figure 4 When the air intake area of ​​the first channel is equal to the air intake area of ​​the second channel, the air intake volume of the first laundry treatment tub 1 is equal to the air intake volume of the second laundry treatment tub 2.

[0124] like Figure 5 As shown, when the second end 542 of the air distribution member 54 rotates to Figure 5 When the air intake area of ​​the first channel is greater than the air intake area of ​​the second channel, the air intake volume of the first laundry treatment tub 1 is greater than the air intake volume of the second laundry treatment tub 2.

[0125] In summary, in the embodiment of the present invention, the air intake amount of the first laundry processing tub 1 and the air intake amount of the second laundry processing tub 2 can be changed by rotating the air dividing member 54 .

[0126] Furthermore, the clothes processing device further includes an air distribution motor 55, which is used to drive the air distribution member 54 to rotate;

[0127] like Figure 6 As shown, the air distribution member 54 further includes a connecting portion between the first end 541 and the second end 542 , and the connecting portion includes a first connecting surface 543 and a second connecting surface 544 that are opposite to each other;

[0128] like Figure 3-Figure 5 As shown, the drying air duct 3 includes a first air duct surface 31 and a second air duct surface 32 that are opposite to each other;

[0129] The first air duct surface 31 is used to limit the counterclockwise rotation of the air distribution member 54 when the first connecting surface 543 abuts the first air duct surface 31, and the second air duct surface 32 is used to limit the clockwise rotation of the air distribution member 54 when the second connecting surface 544 abuts the second air duct surface 32.

[0130] The air dividing member 54 is used to close the first air outlet 52 when it abuts against the first air duct surface 31 , and is used to close the second air outlet 53 when it abuts against the second air duct surface 32 .

[0131] like Figure 3-Figure 5 As shown, when the second end 542 of the air dividing member 54 rotates to contact the first air duct surface 31 or the second air duct surface 32, one of the two clothing processing drums {the first clothing processing drum 1 and the second clothing processing drum} can stop taking in air. At this time, the air intake of the other clothing processing drum is the largest, which will cause a larger airflow impact on the air dividing member 54. In order to prevent the air dividing member 54 from rotating under the impact of strong airflow, the position of the air dividing member 54 is limited by the air duct surface {the first air duct surface 31 and the second air duct surface 32} of the drying air duct 3, thereby improving the accuracy of the air intake. At the same time, it can also prevent the air dividing motor 55 that drives the air dividing member 54 to rotate when it is impacted by a strong airflow.

[0132] The second aspect of the embodiment of the present invention further provides a Figure 7 and Figure 8 The control method of the clothes processing device shown is applied to the clothes processing device of any one of claims 1 to 7, and the control method includes:

[0133] In the double-drum steam care mode, the output current value of the first motor and the output current value of the second motor are obtained, and the rotation angle of the air distribution member is determined according to the output current value of the first motor and the output current value of the second motor;

[0134] The first motor is used to drive the first laundry processing tub 1 to rotate, and the second motor is used to drive the second laundry processing tub 2 to rotate.

[0135] In the embodiment of the present invention, by acquiring the current value of the motor, the load amount in the two laundry processing drums can be obtained, and the amount of steam entering each laundry processing drum is controlled according to the load amount in the two laundry processing drums.

[0136] Furthermore, the method for determining the rotation angle of the air distribution member according to the output current value of the first motor and the output current value of the second motor includes:

[0137] The output current value of the first motor is compared with the output current value of the second motor, and the rotation angle of the air distribution component is determined based on the comparison result.

[0138] That is, by comparing the output current value of the first motor and the output current value of the second motor, the load size in the first clothing processing drum and the second washing drum can be obtained, and the position of the air dividing member 54 can be adjusted according to the load size in the first clothing processing drum and the second washing drum, thereby changing the amount of steam entering the first clothing processing drum 1 and the amount of steam entering the second clothing processing drum 2.

[0139] Specifically, such as Figure 4 As shown, the second end portion 542 of the air distribution member 54 has a first state in the middle of the air inlet 51. When the air distribution member 54 is in the first state, the air intake amount of the first laundry processing tub 1 is the same as the air intake amount of the second laundry processing tub 2.

[0140] The method for determining the rotation angle of the air distribution member 54 based on the comparison result includes:

[0141] When the output current value of the first motor is greater than the output current value of the second motor, the air distribution member 54 is controlled to rotate clockwise from the first state; Figure 3 As shown;

[0142] When the output current value of the first motor is equal to the output current value of the second motor, the air distribution member 54 is kept in the first state; Figure 4 As shown;

[0143] When the output current value of the first motor is less than the output current value of the second motor, the air distribution member 54 is controlled to rotate counterclockwise from the first state; Figure 5 As shown;

[0144] That is, the greater the output current value of the motor, the greater the load in the corresponding laundry treatment drum, that is, the greater the amount of steam required. Conversely, the smaller the output current value of the motor, the smaller the amount of steam required for the corresponding laundry treatment drum. Further;

[0145] The method of controlling the air distribution member 54 to rotate clockwise from the first state includes:

[0146] The clockwise rotation angle of the air distribution member 54 is determined based on the degree to which the output current value of the first motor is greater than the output current value of the second motor, wherein the degree to which the output current value of the first motor is greater than the output current value of the second motor is positively correlated with the clockwise rotation angle of the air distribution member 54;

[0147] The method of controlling the air distribution member 54 to rotate counterclockwise from the first state includes:

[0148] The counterclockwise rotation angle of the air dividing component 54 is determined based on the degree to which the output current value of the first motor is less than the output current value of the second motor, wherein the degree to which the output current value of the first motor is less than the output current value of the second motor is positively correlated with the counterclockwise rotation angle of the air dividing component 54.

[0149] That is, the greater the output current value of the first motor is than the output current value of the second motor, the greater the amount of steam to be distributed to the first laundry processing drum 1, and the greater the counterclockwise rotation angle of the air distribution member 54. Figure 3 shown.

[0150] That is, the smaller the output current value of the first motor is than the output current value of the second motor, the greater the amount of steam to be distributed to the second laundry processing drum 2, and the greater the clockwise rotation of the air distribution member 54, the greater the steam volume. Figure 5 shown.

[0151] In any of the above embodiments, the control method further includes:

[0152] When the double-drum steam care mode ends, the air distribution member 54 is placed in the first state.

[0153] That is, when the clothes processing device finishes the steam care mode, the air distribution element 54 automatically returns to the state as shown in FIG. Figure 4 The first state shown in .

[0154] In any of the above embodiments, the control method further includes:

[0155] Obtain the temperature inside at least one of the first laundry processing drum 1 and the second laundry processing drum 2, and control the speed of the fan 8 according to the temperature value inside at least one of the first laundry processing drum 1 and the second laundry processing drum 2, wherein the fan 8 is connected to the drying duct 3, and is used to circulate the air flow in the drying duct 3.

[0156] In the embodiment of the present invention, the temperature value in the laundry treatment drum is obtained to control the rotation speed of the fan 8, thereby improving the steam care effect on the clothes in the laundry treatment drum.

[0157] Specifically, the method for controlling the rotation speed of the fan 8 according to the temperature value in at least one of the first laundry processing drum 1 and the second laundry processing drum 2 includes:

[0158] When the temperature in at least one of the first laundry processing tub 1 and the second laundry processing tub 2 reaches a first preset temperature value from bottom to top, the fan 8 is controlled to turn on at a low speed;

[0159] When the temperature in at least one of the first laundry processing tub 1 and the second laundry processing tub 2 reaches a second preset temperature value from top to bottom, the fan 8 is controlled to be turned off;

[0160] The first preset temperature value>the second preset temperature value;

[0161] When the fan 8 is turned on at a low speed, the fan rotates at 200 rpm / min-300 rpm / min, preferably, the fan rotates at 250 rpm / min.

[0162] Specifically, when the steam temperature in the first laundry processing drum 1 or the second laundry processing drum 2 reaches a first preset temperature value, the fan 8 is controlled to start at a low speed, and the fan 8 is increased to assist in accelerating the steam flow rate, so that the load absorbs water quickly and improves the steam utilization rate, thereby achieving the effect of improving steam care efficiency and improving steam utilization rate.

[0163] It is worth noting that when the steam temperature in the first laundry processing drum 1 or the second laundry processing drum 2 reaches the first preset temperature value, there is almost no pressure difference between the laundry processing drum and the outside world, and the steam cannot flow quickly and directional in the air duct. Turning on the fan can make the air in the air duct flow quickly into the drum, thereby providing the pressure difference required for steam flow and accelerating the steam flow speed; because excessive air volume can easily blow away the steam, the fan 8 is selected to be turned on at a low speed.

[0164] In any of the above embodiments, the control method further includes:

[0165] When the air distribution member rotates to a preset position according to the determined rotation angle, the fan and the steam generating device are controlled to start;

[0166] After the fan and the steam generating device are started, the temperature value in the first laundry processing tub 1 or the temperature value in the second laundry processing tub 2 is obtained.

[0167] That is, the starting condition of the fan and the steam generating device is that the air distribution member 54 has been rotated to a fixed position.
