For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0048] As shown in Figure 1 The present application introduces a laundry treatment device, which comprises a washing drum 1 for placing laundry, a water containing drum 2 coaxial with the washing drum 1 and rotatable about the shaft, and a dehydration hole is formed on the washing drum 1, and the dehydration hole connects the internal space of the washing drum 1 with the space between the washing drum 1 and the water containing drum 2. The bottom of the water containing drum 2 is connected with a drain pipe 5, and a control device for controlling the flow of water in the water containing drum 2 is arranged on the drain pipe 5, and the drain control device can be a drain pump 6 applied to an upper drain washing machine, or a drain valve applied to a lower drain washing machine.

[0049] As shown in Figure 1 The present application also introduces a laundry treatment device, which comprises a water containing drum 2 for containing water, a washing drum 1 rotatable and used for placing a load to be treated is arranged in the water containing drum 2, and a water supply waterway 3 is used for guiding the water inflow of the washing machine into the washing drum. A nozzle 4 is connected to the water outlet end of the water supply waterway 3, and the nozzle 4 is used for spraying the water flow supplied into the washing drum and washing the laundry placed in the washing drum.

[0050] In the present application, the laundry treatment device can be any device or combination of devices having functions of washing, drying, ironing, refreshing, etc., such as a washing machine, a washing and drying integrated machine, etc.

[0051] In the embodiment of the present application, the laundry treating device is further provided with an additive dispensing device for directly dispensing additives into the washing drum 1. The additive dispensing device can dispense any solid, liquid or gaseous laundry additive into the washing drum, such as any one or combination of washing powder, detergent, rinsing agent, softener, disinfectant, bleaching agent, etc.

[0052] In the embodiment of the present application, the additive dispensing device comprises a water supply channel 3 for water flowing into the additive dispensing device, a dispensing structure for dispensing additives into the water supply channel 3, and a nozzle 4 connected to the outlet of the water supply channel 3 via a conduit, the nozzle 4 being arranged towards the washing drum 1 of the washing machine. When the additive is dispensed, a small amount of water is allowed to flow into the water supply channel, so that the additive solution formed by mixing the additive and the small amount of water in the water supply channel 3 can be directly sprayed into the washing drum 1 by the nozzle 4, thereby significantly improving the utilization rate of the dispensed additive.

[0053] The above arrangement allows the washing machine to directly dispense the additive into the washing drum 1 and directly spray the dispensed additive onto the load in the washing drum 1, thereby achieving a significant technical progress in improving the utilization rate of the additive. At the same time, the additive is directly dispensed through the water channel provided on the dispensing device, avoiding the additive flowing through the water box, which not only reduces the flow path of the additive, but also reduces the amount of rinse water required for dispensing the additive, greatly improving the utilization rate of the additive.

[0054] In the embodiment of the present application, the nozzle 4 can be any water inlet structure that can spray water into the washing drum, such as a shower head, a spray head, etc. In the embodiment of the present application, the nozzle 4 can have only one water outlet or multiple water outlets, so that the spray water flowing into the washing drum from the nozzle can directly flow onto the laundry in the washing drum in any form, such as spraying or showering, to achieve the effect of wetting the laundry and / or dispensing additives.

[0055] In the embodiment of the present application, the water supply channel 3 is integrated on the shell of the additive dispensing device, the outlet of the water supply channel 3 is arranged on the outer side of the shell, the nozzle 4 is arranged outside the shell, and the outlet of the water supply channel 3 is connected to the nozzle 4 through a conduit.

At the same time, the window pad is in the form of a cylindrical structure which can be axially deformed, and the two ends of the window pad are connected to the shell and the water containing barrel respectively, so that the water containing barrel can be connected to the clothes feeding opening through the window pad, and the situation that the water in the water containing barrel flows to the space between the shell and the water containing barrel is prevented.

[0056] By integrating the water supply channel 3 on the shell of the additive dispensing device, the outlet of the water supply channel 3 is directly connected to the nozzle 4, so that the additive and water drawn out through the water supply channel 3 can be sprayed out through the nozzle 4, thereby achieving the purpose that the additive dispensing device is directly sprayed out through the nozzle 4 without passing through the water box part of the dispensing device.

[0057] As shown in the drawings, Figures 1 to 3 In the embodiment of the present application, a rinsing method applied to the clothes treating device is introduced, the washing barrel is rotated at a set rotation-to-stop ratio to drive the clothes in the barrel to move uniformly in the barrel, water is sprayed into the washing barrel, and the sprayed water flow directly washes the clothes which move uniformly in the barrel due to the rotation of the washing barrel.

[0058] In the present application, the clothes are rinsed by spraying water flow, so that the additive remaining on the clothes can be directly washed away by the sprayed water flow, and the problems such as the additive separated from the clothes remaining in the washing barrel and contacting the clothes again are avoided, thereby greatly reducing the residual additive on the clothes after rinsing and significantly improving the rinsing effect of the clothes treating device.

[0059] In the embodiment of the present application, the rinsing process of the clothes treating device includes a spraying and washing step.

[0060] As shown in the drawings, Figure 3 The spraying and washing step specifically includes the following steps,

[0061] The washing barrel is controlled to rotate at a set rotation-to-stop ratio to drive the clothes in the barrel to move uniformly in the barrel.

[0062] Water is sprayed into the washing barrel for a set time t, and the sprayed water is directly sprayed onto the clothes in the washing barrel to spray and wash the clothes.

[0063] The sprayed water in the washing barrel is drained out of the washing machine drain pipe after washing the clothes.

[0064] By using the above method, the water used to spray and rinse the clothes is directly discharged through the drain pipe, preventing additives from remaining in the washing drum and greatly improving the rinsing effect of the clothing treatment equipment.

[0065] In this embodiment of the invention, the washing drum is controlled to rotate at a set rotation-to-stop ratio to drive the clothes inside the drum to move evenly. Specifically, the washing drum rotates for a certain time t21 and then stops rotating for a certain time t22 to agitate the clothes inside the drum and make the clothes more evenly distributed inside the drum.

[0066] In this embodiment of the invention, during the spray rinsing step, the spray water flowing into the washing drum flows out through the dehydration hole on the washing drum and into the water tank sleeved outside the washing drum. The bottom of the water tank is connected to the washing machine drain pipe, and the control device on the drain pipe is in the open state, so that the water in the water tank is directly discharged out along the drain pipe.

[0067] In this embodiment, the water container 2 is equipped with a water level sensor 7 to detect the water level inside; the water level sensor 7 can be any existing device capable of detecting the water level inside the water container, such as... Figure 1 As shown, the water level sensor 7 is specifically configured as follows: an air guide pipe is connected to the bottom of the water tank 2, and the other end of the air guide pipe is connected to a pressure sensor. The water level in the water tank is obtained by using the pressure detected by the pressure sensor.

[0068] like Figure 3 As shown in this embodiment of the invention, during the spray rinsing step, the water level in the water tank is monitored. When the water level in the water tank reaches or is about to reach the minimum height of the washing drum, the spraying of water into the washing drum is stopped. This method prevents water containing additives rinsed off the clothes from coming into contact with the clothes in the washing drum, thereby effectively reducing the amount of additive residue on the clothes after rinsing and greatly improving the rinsing effect.

[0069] In this embodiment of the invention, the spray water is injected from the top of the washing drum opening towards the bottom of the washing drum, so that the spray water always sprays and rinses the lowest area of ​​the washing drum, and combined with the synchronous rotation of the washing drum, achieves a comprehensive rinsing effect on the clothes. Preferably, the spray water covers the entire area of ​​the washing drum from the opening to the bottom, so that the spray water can spray and rinse the clothes inside the washing drum from all directions.

[0070] In this embodiment of the invention, after the spray rinsing step is completed, a dehydration step is performed. This dehydrates the clothing, which contains a high amount of moisture after spray rinsing, separating the clothing from the water phase, further improving the cleanliness of the rinsed clothing and effectively reducing the amount of additives remaining on the clothing.

[0071] The dehydrating step performed after the spraying rinsing step in the embodiment of the present application can be any existing form of dehydrating step for clothes; for example, the dehydrating step includes controlling the washing drum to rotate at a set speed in one direction, and the clothes in the washing drum rotate together with the inner wall of the washing drum under the action of centrifugal force, so that the water on the clothes is separated from the clothes under the action of centrifugal force and flows out of the washing drum and into the water tub.

[0072] As shown in Figure 2 the embodiment of the present application, the rinsing process of the clothes treatment device includes the following steps,

[0073] S1, a spraying rinsing step;

[0074] S2, a dehydrating step;

[0075] S3, a conventional rinsing step;

[0076] S4, a spraying rinsing step;

[0077] S5, completion of rinsing.

[0078] By performing the spraying rinsing step at the beginning of the rinsing program, the additives and other substances attached to the surface of the clothes are cleaned, so that the additives on the surface of the clothes can be effectively removed before the conventional rinsing, and the occurrence of excessive residual additives and excessive foam in the drum during the conventional rinsing is prevented. In addition, the spraying rinsing step is performed again after the conventional rinsing, so that the additives adhered to the surface of the clothes again during the rinsing process due to the rinsing water are completely removed, and the additives on the clothes can be completely removed after the rinsing program, thereby greatly reducing the residual amount of additives on the clothes after the rinsing program and significantly improving the rinsing effect.

[0079] In the embodiment of the present application, the conventional rinsing step in the step S3 includes disconnecting the drain pipe, filling water into the water tub, retaining the water in the water tub, starting the washing drum to run at a set rotation-to-stop ratio after the water reaches a set rinsing water level, and using the water in the water tub and flowing into the washing drum to rinse the clothes; and opening the drain pipe to completely drain the water in the water tub when the rinsing completion condition is reached. Further preferably, one or more rinsing steps can be provided in the step S3 to further improve the rinsing effect of the clothes.

[0080] In the embodiment of the present application, the washing machine starts to perform a dehydrating process after the completion of the rinsing process and the step S5, so that the dehydrating step does not need to be performed again after the step S4. Thus, the spraying rinsing step performed again after the conventional rinsing does not need to be connected to the dehydrating step, which not only reduces the number of steps, but also achieves the purpose of dehydrating and spinning the clothes with a high water content after the spraying rinsing.

[0081] In the embodiment of the present application, the time t1 for which the water is sprayed into the washing drum in step S1 is less than or equal to the time t2 for which the water is sprayed into the washing drum in step S1, so as to reasonably set the logic timing of the rinsing program, and to compress the program length while improving the rinsing effect.

[0082] In the embodiment of the present application, the water spraying into the washing drum comprises the following: every time interval t11, the water is sprayed into the washing drum for a time interval t12. Thus, the water spraying process is in the form of interval water spraying, so that the water flow can be in maximum contact with the clothes in the washing drum, and the water flow on the surface of the clothes is reduced, thereby improving the rinsing effect of the water spraying on the clothes.

[0083] The above is only the preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above-mentioned technical content without departing from the scope of the technical solution of the present application, and any simple modification, equivalent change and modification of the above-mentioned embodiments according to the technical essence of the present application are still within the scope of the present application.
