Description

[0001] This application claims priority to Chinese patent application CN202211543213.X, filed on December 2, 2022, entitled “Isolation Washing Control Method for Drum Washing Machine”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of washing equipment technology, and specifically provides a method for isolating and controlling washing in washing equipment. Background Technology

[0003] Washing machines are common household appliances for washing clothes. Based on their washing methods, washing machines can be broadly classified into top-loading (pulsator) washing machines and front-loading (drum) washing machines. Taking front-loading washing machines as an example, the washing process typically involves filling the space between the inner and outer drums with water, ensuring the water level is higher than the inner drum. The clothes are then soaked in the water, and the inner drum rotates and "tumbles" the clothes to wash them. If the washing machine is used for an extended period, bacteria will inevitably grow between the inner and outer drums. This can lead to secondary contamination of clothes when the user washes them again, which is detrimental to health.

[0004] In addition, existing washing machines use the same spray volume and spray method for clothes of different weights. However, clothes of different weights occupy different spaces in the inner drum and have different water absorption capacities. If the same spray volume and spray method are used for all clothes, the clothes cannot be effectively wetted, resulting in a waste of water resources.

[0005] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0006] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that existing washing machines cannot guarantee the effective wetting of clothes, resulting in water waste.

[0007] This invention provides a method for isolating and controlling a washing device. The washing device includes an inner drum, an outer drum, and a spraying device. The inner drum is rotatably disposed inside the outer drum and is used to hold clothes to be washed. A gap cavity is formed between the inner drum and the outer drum. The spraying device is configured to spray water into the inner drum. The control method includes the following steps: obtaining the actual weight of the clothes to be washed in the inner drum; determining the spray volume of water and detergent and the spraying mode of the spraying device based on the actual weight of the clothes; during the washing stage, controlling the spraying device to spray water and / or detergent into the clothes to be washed in the inner drum according to the determined spray volume and spraying mode, and controlling the inner drum to rotate; throughout the washing process, controlling the water in the gap cavity to never contact the inner drum.

[0009] In a specific implementation of the isolation washing control method for washing equipment, the step of "controlling the spray device to spray water and / or washing liquid in a single cycle" specifically includes: first controlling the spray device to spray washing liquid; then controlling the spray device to spray water.

[0010] In a specific implementation of the isolation washing control method for washing equipment, the step of "controlling the spray device to spray water and / or washing liquid onto the clothes to be washed in the inner drum according to a determined spray volume and spray method and controlling the rotation of the inner drum" specifically includes: when the actual weight is higher than the preset weight, controlling the spray device to spray water and / or washing liquid multiple times according to a determined spray volume and controlling the rotation of the inner drum.

[0012] In a specific implementation of the isolation washing control method for washing equipment, steps S11 and S12 are executed repeatedly, then steps S11 and S13 are executed repeatedly, and then steps S11 and S14 are executed repeatedly.

[0013] In a specific implementation of the isolation washing control method for washing equipment, the step of "controlling the spray device to spray water and / or washing liquid onto the clothes to be washed in the inner drum according to a determined spray volume and spray method and controlling the rotation of the inner drum" further includes: S110, controlling the spray device to spray washing liquid onto the clothes to be washed in the inner drum; S120, controlling the inner drum to reciprocate; S130, controlling the spray device to spray water onto the clothes to be washed in the inner drum.

[0014] In a specific implementation of the isolation washing control method for washing equipment, steps S110 and S120 are executed repeatedly, and then steps S120 and S130 are executed repeatedly.

[0025] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0026] It should be noted that although the steps of the control method of the present invention are described in a specific order in the description of the present invention, these orders are not restrictive. Without departing from the basic principles of the present invention, those skilled in the art can perform the steps in different orders.

[0027] This invention provides a method for isolating washing control in a washing device. In this invention, the washing device can be a drum washing machine or a top-loading washing machine. The control method of this invention is described below using a drum washing machine as an example.

[0028] First refer to Figure 1 and Figure 2 This figure is a schematic diagram of the washing device of the present invention. Figure 1 , Figure 2 As shown, the washing device of the present invention includes an inner drum 1, an outer drum 2, and a spray device (not shown in the figure). The inner drum 1 is rotatably disposed inside the outer drum 2 and is used to hold clothes to be washed. A gap cavity 4 is formed between the inner drum 1 and the outer drum 2. A window gasket 3 is provided between the open end of the front structure of the outer drum 2 and the housing of the washing device. The spray device is preferably mounted on the window gasket 3 and configured to spray into the inner drum 1. Of course, the spray device can also be installed in other positions besides the window gasket 3, as long as it can spray into the inner drum 1. The present invention does not impose any limitation on the installation position of the spray device.

[0029] Then refer to Figure 3 The figure is a flowchart illustrating the main steps of the isolation washing control method of the washing equipment of the present invention. Figure 3 As shown, the control method of the present invention includes:

[0030] S1, obtain the actual weight of the laundry inside the inner drum 1;

[0031] S2, determine the amount of water and detergent to be sprayed and the spraying method of the spraying device based on the actual weight of the clothes to be washed;

[0032] S3, During the washing stage, the spray device is controlled to spray water and / or detergent onto the clothes to be washed in the inner drum 1 according to a determined spray volume and spray method, and the inner drum 1 is controlled to rotate.

[0033] S4, throughout the entire washing process, the water in the control gap cavity 4 is kept away from the inner drum 1.

[0034] In step S1, the actual weight of the clothes to be washed can be obtained by fuzzy weighing or by controlling the inner drum 1 to rotate to obtain the corresponding output current value, and the weight of the clothes to be washed can be obtained according to the mapping relationship between the output current value and the weight of the clothes.

[0035] In step S3, the step of "controlling the spray device to spray water and / or detergent onto the clothes to be washed in the inner drum 1 according to a determined spray volume and spray pattern during the washing stage and controlling the rotation of the inner drum 1" specifically includes:

[0036] When the actual weight is lower than the preset weight, the spray device is controlled to spray water and / or washing liquid in a single spraying at a determined spraying volume.

[0037] While controlling the spraying device to spray water and / or washing liquid once, control the inner cylinder to reciprocate.

[0038] Specifically, when the weight of the clothes to be washed is small, there is no need to spray multiple times; the required amount of spray can be sprayed directly in a single spray. Furthermore, the inner drum can be controlled to rotate at a low speed while the spraying device is spraying, so that the clothes are evenly distributed in the inner drum. Alternatively, the inner drum can be controlled to rotate after the spraying device has finished spraying.

[0039] Preferably, the step of "controlling the spray device to spray water and / or detergent in a single cycle" specifically includes: first controlling the spray device to spray detergent, and then controlling the spray device to spray water. Specifically, spraying detergent first ensures the optimal amount of detergent added, allowing the clothes to fully absorb the detergent. The spray device can be a single unit, spraying detergent and water sequentially, or it can be two units, spraying detergent and water separately. Furthermore, the inner drum can be controlled to rotate back and forth after the detergent is sprayed and before the water is sprayed, or the inner drum can be controlled to rotate back and forth after both water and detergent have been sprayed. All these adjustments fall within the scope of protection of this invention.

[0040] In step S3, the step of "controlling the spray device to spray water and / or detergent onto the clothes to be washed in the inner drum 1 according to a determined spray volume and spray pattern during the washing stage and controlling the rotation of the inner drum 1" further includes:

[0041] When the actual weight is higher than the preset weight, the spraying device is controlled to spray water and / or washing liquid multiple times according to the determined spraying volume and the inner cylinder 1 is controlled to rotate.

[0042] Specifically, the step of "controlling the spraying device to spray water and / or washing liquid multiple times according to a determined spray volume and controlling the rotation of the inner cylinder 1" further includes:

[0043] S11, control the spraying device to spray a mixture of washing liquid and water onto the clothes to be washed in the inner drum 1;

[0044] S12 controls the inner cylinder 1 to reciprocate;

[0045] S13 controls the inner cylinder 1 to reciprocate.

[0046] S14 controls the reciprocating rotation of the inner cylinder 1.

[0047] Preferably, steps S11 and S12 are executed repeatedly, then steps S11 and S13 are executed repeatedly, and then steps S11 and S14 are executed repeatedly.

[0048] Specifically, when there is a large amount of laundry to be washed, multiple sprays are performed according to a determined spray volume, and the inner drum is controlled to rotate at a low speed to ensure even distribution of the laundry within the drum, guaranteeing effective wetting and improving the soaking efficiency. The inner drum rotation and spraying can be performed simultaneously, i.e., spraying while rotating, or spraying first and then rotating; all these adjustments fall within the scope of this invention. For example, the inner drum is first controlled to rotate back and forth at 90 rpm, then at 30 rpm, followed by a 90-degree oscillation, and finally at 45 rpm.

[0049] In an alternative embodiment, the step of "controlling the spraying device to spray water and / or detergent onto the clothes to be washed in the inner drum 1 according to a determined spraying pattern and controlling the rotation of the inner drum 1" further includes:

[0050] S110, control the spray device to spray washing liquid onto the clothes to be washed in the inner drum 1;

[0051] S120 controls the reciprocating rotation of the inner cylinder 1;

[0052] S130, controls the spray device to spray water onto the clothes to be washed in the inner drum 1.

[0053] Preferably, steps S110 and S120 are executed repeatedly, and then steps S120 and S130 are executed repeatedly.

[0054] Specifically, during one execution of steps S110 and S120, the spray device is first controlled to spray detergent onto the clothes to be washed in the inner drum 1, and then the inner drum 1 is controlled to rotate back and forth, and this cycle is repeated multiple times until the preset amount of detergent and number of sprays are met. Similarly, during one execution of steps S120 and S130, the spray device is first controlled to spray water onto the clothes to be washed in the inner drum 1, and then the inner drum 1 is controlled to rotate back and forth, and this cycle is repeated multiple times until the preset amount of water and number of sprays are met.

[0055] Of course, during the execution of steps S110 and S120, the spraying of the washing liquid and the rotation of the inner drum can be controlled simultaneously, or the rotation of the inner drum can be controlled first, followed by the spraying of the washing liquid. Similarly, during the execution of steps S120 and S130, the spraying of the water and the rotation of the inner drum can be controlled simultaneously, or the rotation of the inner drum can be controlled first, followed by the spraying of the water. These adjustments do not deviate from the principles of the present invention and therefore fall within the scope of protection of the present invention.

[0056] Step S4 specifically includes the following steps:

[0057] Throughout the washing process, the actual water level height inside the gap chamber 4 is acquired in real time.

[0058] When the actual water level is higher than the preset water level, the gap cavity 4 is drained to ensure that the water in the gap cavity 4 never comes into contact with the inner cylinder 1.

[0059] In this embodiment, a water level sensor (not shown in the figure) is installed in the gap cavity 4 to detect the actual water level height inside the gap cavity 4. The preset water level height is the water level height that never contacts the edge of the inner cylinder 1.

[0060] Alternatively, in an alternative implementation, step S4 specifically includes the following steps:

[0061] Throughout the washing process, the gap cavity 4 is kept in a draining state to ensure that the water inside the gap cavity 4 never comes into contact with the inner drum 1. Maintaining the draining state of the gap cavity 4 can be achieved by continuously opening the drain outlet connected to the gap cavity 4, utilizing the principle of gravity drainage. Alternatively, drainage can be achieved by continuously operating a drain pump on the drain pipe connected to the gap cavity 4, utilizing the principle of powered drainage.

[0062] Throughout the washing process, the spray device sprays water and / or detergent directly onto the clothes in the inner drum 1. The water and / or detergent first enter the inner drum 1 to contact the clothes, then enters the gap cavity 4, and finally exits through the gap cavity 4. This ensures that the water and / or detergent sprayed onto the clothes is always clean. Simultaneously, the liquid in the gap cavity 4 never comes into contact with the inner drum 1. When the inner drum 1 rotates, the water in the gap cavity 4 does not re-enter the inner drum 1, preventing bacteria from the gap cavity 4 from being carried into the inner drum 1 and adhering to the clothes, thus avoiding secondary contamination. Furthermore, because the water in the gap cavity 4 never comes into contact with the inner drum 1, the inner drum 1 does not need to overcome the resistance caused by water contact during rotation, thus reducing power consumption compared to existing washing equipment. In addition, by using a spray method to wash the clothes, the liquid can be sprayed more evenly onto the clothes, ensuring a good washing effect while also saving water.

[0063] It should be noted that "throughout the entire washing process" in step S4 refers to the entire washing program, including not only the washing stage, but also the rinsing stage and the spin-drying stage.

[0064] Furthermore, the washing liquid mentioned above can be a undiluted washing liquid or a mixture of undiluted washing liquid and water; the present invention does not limit this.

[0065] Furthermore, the control method of the present invention also includes:

[0066] During the washing stage, after the spraying device sprays water and / or washing liquid onto the clothes to be washed in the inner drum 1 according to the determined spraying volume and spraying method, the spraying device sprays water onto the clothes to be washed in the inner drum 1 for a preset time, and judges whether the water level in the gap cavity 4 has changed.

[0067] When the water level in the gap cavity 4 does not change, control the spray device to continue spraying water onto the clothes to be washed in the inner drum 1;

[0068] When the water level in the gap cavity 4 changes, the control spray device stops spraying water onto the clothes to be washed in the inner drum 1.

[0069] Specifically, after the spraying is finished, in order to check the water absorption saturation of the clothes to be washed, for example, while the inner drum is rotating, the spraying device is controlled to spray water onto the clothes to be washed for 10 seconds. After 30 seconds, the water level change in the gap cavity is observed. If the water level changes, it means that the clothes to be washed are in a water-saturated state, so the spraying is stopped. If the water level does not change, it means that the clothes to be washed are in a water-unsaturated state, so the spraying continues to replenish water to ensure that the clothes to be washed are effectively wetted.

[0070] See below. Figure 4 The figure is a possible complete flowchart of the isolation washing control method of the washing equipment of the present invention. Figure 4 As shown, a possible complete process of the isolation washing control method of the washing equipment of the present invention is as follows:

[0071] S101, Obtain the actual weight of the laundry inside the inner drum 1;

[0072] S102, determine the amount of water and detergent to be sprayed based on the actual weight of the clothes to be washed;

[0073] S103, compare the actual weight with the preset weight;

[0074] If the actual weight is less than the preset weight, proceed to step S104.

[0075] If the actual weight is greater than the preset weight, then proceed to step S105;

[0076] S104, control the spraying device to spray water and / or washing liquid in a single spraying according to a determined spraying volume and control the inner cylinder 1 to reciprocate.

[0077] S105, control the spraying device to spray water and / or washing liquid multiple times according to the determined spraying volume and control the inner cylinder 1 to rotate;

[0078] S106, control the spray device to spray water onto the clothes to be washed in the inner drum 1 for 10 seconds;

[0079] S107, Determine whether the water level in the gap cavity 4 has changed;

[0080] If so, proceed to step S108;

[0081] If not, proceed to step S109;

[0082] S108, control the spray device to stop spraying water onto the clothes to be washed in the inner drum 1;

[0083] S109, control the spray device to continue spraying water onto the clothes to be washed in the inner drum 1;

[0084] S110, throughout the entire washing process, the water in the control gap cavity 4 is kept away from the inner drum 1.

[0085] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
