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, the existing rinsing method involves the inner drum slowing down to a stop after each high-speed spin-drying cycle before spraying water. This requires redistributing the clothes each time, resulting in a longer rinsing time.

[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 problem, namely, to solve the problem that bacteria between the inner and outer drums of existing washing equipment can adhere to the clothes and cause secondary pollution of the clothes.

[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 spray 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 spray device is configured to spray water into the inner drum. The control method includes the following steps: during the washing stage, controlling the spray device to spray water and / or detergent into the clothes to be washed in the inner drum and controlling the rotation of the inner drum; during the rinsing stage, before the final rinsing, alternately controlling the inner drum to rotate at increasing and decreasing speeds; obtaining the actual rotational speed of the inner drum; when the actual rotational speed of the inner drum decreases to a preset speed, controlling the spray device to spray water into the clothes to be washed in the inner drum; and controlling the water in the gap cavity to never contact the inner drum throughout the entire process.

[0008] In a specific embodiment of the isolation washing control method for the above-mentioned washing equipment, the control method further includes: during the rinsing stage, during the last rinsing, when the actual rotation speed of the inner drum drops back to the preset rotation speed, controlling the spray device to spray water and fabric softener onto the clothes to be washed in the inner drum; controlling the inner drum to increase its rotation speed; and controlling the inner drum to decrease its rotation speed until it stops.

[0009] In a specific embodiment of the isolation washing control method for the above-mentioned washing equipment, the control method further includes: during the rinsing stage, during the last rinsing, when the actual rotation speed of the inner drum drops back to the preset rotation speed, controlling the spray device to spray water onto the clothes to be washed in the inner drum; controlling the inner drum to increase its rotation speed; and controlling the inner drum to decrease its rotation speed until it stops.

[0010] In a specific implementation of the isolation washing control method for the above-mentioned washing equipment, the step of "controlling the water in the gap cavity to never contact the inner drum throughout the entire washing process" specifically includes: acquiring the actual water level in the gap cavity in real time throughout the entire washing process; when the actual water level is higher than the preset water level, controlling the gap cavity to drain water so that the water in the gap cavity never contacts the inner drum.

[0011] In a specific embodiment of the isolation washing control method for the above-mentioned 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 and controlling the rotation of the inner drum" specifically includes: S11, controlling the spray device to spray water onto the clothes to be washed in the inner drum; S12, controlling the inner drum to rotate back and forth; S13, controlling the spray device to spray washing liquid onto the clothes to be washed in the inner drum; first, steps S11 and S12 are executed repeatedly, and then steps S12 and S13 are executed repeatedly.

[0012] In a specific embodiment of the isolation washing control method for the above-mentioned 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 and controlling the rotation of the inner drum" specifically 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 rotate back and forth; S130, controlling the spray device to spray water onto the clothes to be washed in the inner drum; first, steps S110 and S120 are executed repeatedly, and then steps S120 and S130 are executed repeatedly.

[0013] In a specific embodiment of the isolation washing control method of the above-mentioned 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 and controlling the rotation of the inner drum" specifically includes performing the following steps alternately: S1100, controlling the spray device to spray a mixture of washing liquid and water onto the clothes to be washed in the inner drum; S1200, controlling the inner drum to reciprocate.

[0014] In a specific implementation of the isolation washing control method for the above-mentioned 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 and controlling the rotation of the inner drum" specifically includes: first controlling the spray device to spray water onto the clothes to be washed in the inner drum; then controlling the spray device to spray washing liquid onto the clothes to be washed in the inner drum; and after the clothes to be washed in the inner drum are fully wetted, controlling the inner drum to rotate back and forth.

[0015] In a specific embodiment of the isolation washing control method of the above-mentioned 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 and controlling the rotation of the inner drum" specifically includes: first controlling the spray device to spray washing liquid onto the clothes to be washed in the inner drum; then controlling the spray device to spray water onto the clothes to be washed in the inner drum; and after the clothes to be washed in the inner drum are fully wetted, controlling the inner drum to rotate back and forth.

[0016] In a specific implementation of the isolation washing control method for the above-mentioned 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 and controlling the rotation of the inner drum" specifically includes: first controlling the spray device to spray a mixture of washing liquid and water onto the clothes to be washed in the inner drum; and after the clothes to be washed in the inner drum are fully wetted, controlling the inner drum to rotate back and forth.

[0017] With the above technical solution, during the entire washing process, the spray device sprays water and / or detergent directly onto the clothes to be washed in the inner drum. The sprayed water and / or detergent first enter the inner drum and contact the clothes, then enters the gap cavity, and finally exits through the gap cavity. This ensures that the water and / or detergent sprayed onto the clothes is always clean. Simultaneously, the water in the gap cavity never comes into contact with the inner drum. When the inner drum rotates, the water in the gap cavity will not re-enter the inner drum, preventing bacteria from the gap cavity from being carried into the inner drum and adhering to the clothes, thus avoiding secondary contamination. Furthermore, because the water in the gap cavity never comes into contact with the inner drum, the inner drum does not need to overcome the resistance caused by water contact during rotation, thus reducing power consumption compared to existing drum washing machines. In addition, by using a spray method to wash clothes, water and / or detergent can be sprayed more evenly onto the clothes, ensuring washing effectiveness while also saving water.

[0018] Furthermore, before the final rinse in the rinsing stage, while the inner drum rotates at low speed, the spray device sprays water onto the clothes to be washed, allowing the clothes to fully absorb the water. When the inner drum rotates at high speed, it spins the water off the clothes, achieving a thorough rinse. This process is repeated, ensuring that the clothes remain attached to the drum wall and do not fall off. This eliminates the need for redistribution of the clothes after each rinse. In contrast, existing rinsing methods require the inner drum to slow down and stop after each high-speed spin-drying cycle before spraying water again, necessitating redistribution of the clothes each time. Compared to existing methods, the rinsing method of this invention saves rinsing time and improves rinsing efficiency. Attached Figure Description

[0026] 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.

[0027] 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.

[0028] Example 1

[0029] 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.

[0030] First refer to Figure 1 and Figure 2 This figure is a schematic diagram of the structure of the drum washing machine of the present invention. Figure 1 , Figure 2 As shown, the drum washing machine 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 machine. The spray device is preferably mounted on the window gasket 3 and configured to spray into the inner drum 1. Specifically, the spray device can be configured as a nozzle, which is connected to the water tank and / or detergent dispenser of the drum washing machine through a pipeline. A pump or other power device can be provided on the pipeline to provide spray pressure. Of course, the spray device can also be installed in other locations besides the window gasket 3, or configured in other forms besides a nozzle, as long as it can spray into the inner drum 1. The present invention does not impose any limitations on the location and physical form of the spray device.

[0031] 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:

[0032] Step S1: During the washing stage, control the spray device to spray water and / or detergent onto the clothes to be washed in the inner drum 1 and control the inner drum to rotate.

[0033] Step S2: During the rinsing stage, before the final rinsing, the inner drum 1 is controlled to rotate at increasing speed and decreasing speed alternately.

[0034] Step S3: Obtain the actual rotational speed of the inner cylinder 1;

[0035] Step S4: When the actual rotation speed of the inner drum 1 drops to the preset rotation speed, control the spray device to spray water onto the clothes to be washed inside the inner drum 1.

[0036] Step S5: Throughout the entire procedure, the water in the gap cavity 4 is controlled to never come into contact with the inner cylinder 1.

[0037] During the washing stage, step S1 specifically includes the following steps:

[0038] Step S11: Control the spray device to spray water onto the clothes to be washed inside the inner drum 1;

[0039] Step S12: Control the inner cylinder 1 to rotate back and forth;

[0040] Step S13: Control the spray device to spray washing liquid onto the clothes to be washed in the inner drum 1.

[0041] Preferably, steps S11 and S12 are executed repeatedly to wet the clothes to be washed, and then steps S12 and S13 are executed repeatedly to allow the washing liquid to adhere to the clothes to be washed.

[0042] Specifically, during one execution of steps S11 and S12, 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 spray water volume and spray number are met. Similarly, during one execution of steps S12 and S13, 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 spray detergent volume and spray number are met.

[0043] Of course, during the execution of steps S11 and S12, the spray water and the inner drum rotation can be controlled simultaneously, or the inner drum rotation can be controlled first, followed by the spray water. Similarly, during the execution of steps S12 and S13, the spray washing liquid and the inner drum rotation can be controlled simultaneously, or the inner drum rotation can be controlled first, followed by the spray washing liquid. These adjustments do not deviate from the principles of the present invention and therefore fall within the protection scope of the present invention.

[0044] Furthermore, the aforementioned washing liquid can be a undiluted washing liquid or a mixture of undiluted washing liquid and water; this invention does not limit this. For example, water can be sprayed onto the clothes to be washed first, ensuring they are fully wetted, and then a high-concentration washing liquid can be sprayed onto them, allowing the washing liquid to adhere to the clothes. Alternatively, water can be sprayed onto the clothes to be washed first, ensuring they are damp, and then a low-concentration washing liquid can be sprayed onto them, ensuring they are fully wetted and coated with washing liquid. This method, by first dampening but not completely soaking the clothes, and then allowing them to be fully soaked under the action of the washing liquid, allows the washing liquid to adhere to the clothes better and more evenly, ensuring the subsequent washing effect, while also saving on the amount of washing liquid and spray water used.

[0045] Preferably, step S13 further includes:

[0046] Step S131: Control the spraying device to spray a mixture of washing liquid and water onto the clothes to be washed in the inner drum 1.

[0047] In steps S2-S4, before the final rinse in the rinsing stage, the inner drum 1 rotates at low speed while the spray device sprays water onto the clothes to be washed, allowing the clothes to fully absorb water. When the inner drum 1 rotates at high speed, the water on the clothes is spun dry, achieving a clean rinse. This process is repeated to ensure that the clothes to be washed always stick to the drum wall and do not fall off. In this way, the clothes do not need to be redistributed after each rinse. In contrast, existing rinsing methods require the inner drum to slow down to a stop after each high-speed spin-drying process before spraying water, which necessitates redistributing the clothes each time. Compared with existing rinsing methods, the rinsing method of this invention saves rinsing time and improves rinsing efficiency.

[0048] The control method of the present invention further includes:

[0049] Step S61: During the rinsing stage, during the last rinse, when the actual rotation speed of the inner drum 1 drops back to the preset rotation speed, the spray device is controlled to spray water and fabric softener onto the clothes to be washed inside the inner drum 1.

[0050] Step S7: Control the inner cylinder to rotate at an increased speed;

[0051] Step S8: Control the inner cylinder to rotate at a reduced speed until it stops.

[0052] In steps S6-S8, during the final rinse of the rinsing stage, when the inner drum 1 rotates at low speed, the spray device sprays water and fabric softener onto the clothes to be washed, so that the clothes can fully and evenly absorb the water and fabric softener. When the inner drum 1 rotates at high speed, it spins the water off the clothes and then stops, thus achieving a clean rinse.

[0053] Alternatively, in an alternative embodiment of step S61, the control method of the present invention further includes:

[0054] Step S62: During the rinsing stage, during the last rinse, when the actual rotation speed of the inner drum drops back to the preset rotation speed, the spray device is controlled to spray water onto the clothes to be washed in the inner drum 1.

[0055] In step S62, during the final rinse of the rinsing stage, the inner drum 1 rotates at low speed while the spray device sprays water onto the clothes to be washed, allowing the clothes to fully and evenly absorb water. Then, similar to steps S7 and S8 above, the inner drum 1 rotates at high speed to dehydrate and spin-dry the clothes, and then stops, thus achieving a clean rinse.

[0056] Step S5 specifically includes the following steps:

[0057] Step S51: Throughout the entire program, the actual water level height inside the gap cavity 4 is acquired in real time.

[0058] Step S52: When the actual water level is higher than the preset water level, control the drainage of the gap cavity 4 so 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 S5 specifically includes the following steps:

[0061] Step S53: Throughout the entire procedure, the gap cavity 4 is kept in a draining state so that the water in the gap cavity 4 never comes into contact with the inner cylinder 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 dynamic 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 "in the whole process" in step S5 refers to the entire washing process, including not only the washing stage, but also the rinsing stage and the spin-drying stage.

[0064] Example 2

[0065] The difference from Embodiment 1 is that, in the washing stage, step S1 specifically includes the following steps:

[0066] Step S110: Control the spraying device to spray washing liquid onto the clothes to be washed in the inner drum 1;

[0067] Step S120: Control the inner cylinder 1 to reciprocate.

[0068] Step S130: Control the spray device to spray water onto the clothes to be washed in the inner drum 1.

[0069] Preferably, steps S110 and S120 are executed repeatedly to allow the washing liquid to adhere to the clothes to be washed, and then steps S120 and S130 are executed repeatedly to wet the clothes to be washed.

[0070] 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.

[0071] Of course, during the execution of steps S110 and S120, the spraying of washing liquid and the rotation of the inner drum 1 can be controlled simultaneously, or the rotation of the inner drum 1 can be controlled first, followed by the spraying of washing liquid. Similarly, during the execution of steps S120 and S130, the spraying of water and the rotation of the inner drum 1 can be controlled simultaneously, or the rotation of the inner drum 1 can be controlled first, followed by the spraying of water. These adjustments do not deviate from the principles of the present invention and therefore fall within the protection scope of the present invention.

[0072] Preferably, step S110 further includes:

[0073] Step S1101: Control the spraying device to spray a mixture of washing liquid and water onto the clothes to be washed in the inner drum 1.

[0074] Example 3

[0075] The difference from Embodiment 1 is that, in the washing stage, step S1 specifically includes the following steps:

[0076] Step S1100: Control the spraying device to spray a mixture of detergent and water onto the clothes to be washed in the inner drum 1;

[0077] Step S1200: Control the inner cylinder 1 to reciprocate.

[0078] Steps S1100 and S1200 are executed alternately and repeatedly until the preset spray volume and spray count are met.

[0079] In the above steps, by alternating between controlled spraying and rotation of the inner drum 1 for washing, on the one hand, the clothes to be washed can be dispersed when the inner drum 1 rotates, avoiding the clothes from being stacked, and the sprayed mixed solution can be sprayed more evenly on the clothes to be washed. On the other hand, the jogging water inlet method can ensure the accuracy of the water level entering the gap cavity 4, so as to ensure precise control of drainage and avoid the inner drum 1 from contacting the water in the gap cavity 4 due to untimely drainage.

[0080] Example 4

[0081] The difference from Embodiment 1 is that, in the washing stage, step S1 specifically includes the following steps:

[0082] First, control the spray device to spray water onto the clothes to be washed inside the inner drum 1;

[0083] Then control the spray device to spray washing liquid onto the clothes to be washed in the inner drum 1;

[0084] After the clothes to be washed in the inner drum 1 are fully wetted, control the inner drum 1 to rotate back and forth.

[0085] Preferably, "controlling the spray device to spray washing liquid onto the clothes to be washed in the inner drum 1" further includes:

[0086] The spray device is controlled to spray a mixture of detergent and water onto the clothes to be washed inside the inner drum 1.

[0087] Example 5

[0088] The difference from Embodiment 1 is that, in the washing stage, step S1 specifically includes the following steps:

[0089] First, control the spray device to spray washing liquid onto the clothes to be washed in the inner drum 1;

[0090] Then control the spray device to spray water onto the clothes to be washed in the inner drum 1;

[0091] After the clothes to be washed in the inner drum 1 are fully wetted, control the inner drum 1 to rotate back and forth.

[0092] Preferably, "controlling the spray device to spray washing liquid onto the clothes to be washed in the inner drum 1" further includes:

[0093] The spray device is controlled to spray a mixture of detergent and water onto the clothes to be washed inside the inner drum 1.

[0094] Example 6

[0095] The difference from Embodiment 1 is that, in the washing stage, step S1 specifically includes the following steps:

[0096] First, control the spray device to spray a mixture of detergent and water onto the clothes to be washed in the inner drum 1;

[0097] After the clothes to be washed in the inner drum 1 are fully wetted, control the inner drum 1 to rotate back and forth.

[0098] In practice, the concentration of the mixed solutions in Examples 3 and 6 is much lower than that in Examples 1, 2, 4, and 5, because in the embodiments of Examples 3 and 6, water is no longer sprayed separately; the water required for washing is completely mixed with the washing liquid. The specific concentration can be flexibly set by those skilled in the art as needed, and the present invention does not impose any restrictions on this, as long as the degree of washing and the cleanliness of subsequent rinsing are guaranteed.

[0099] In Embodiments 4, 5, and 6 above, by adopting a spray-then-rotate washing mode, it is ensured that the clothes to be washed fully absorb water and / or detergent before being shaken out, thus guaranteeing the washing effect. In actual operation, the above-mentioned spray-then-rotate washing mode is suitable for situations where there are few clothes to be washed, avoiding uneven spraying of the clothes due to too many clothes, which would affect the washing effect.

[0100] 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: S11-S12-S13-S2-S3-S4-S61-S7-S8-S5.

[0101] 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.
