Description

Technical Field

[0001] The invention belongs to the field of washing equipment, and in particular, relates to a drum cleaning device and a cleaning method for washing equipment. Background Art

[0002] The washing machine is one of the commonly used household appliances. While the washing machine cleans clothes, the cleaning problem of the washing machine itself also troubles users. The reason is that the stains washed off our clothes will adhere to the interlayer gap between the inner and outer drums of the washing machine. During the washing process, there is no strong water flow between the outer wall of the inner drum and the outer drum, especially the back part of the drum, and deposited dirt will form over time. The inside of the washing machine is humid, which naturally forms a natural breeding ground for bacteria. Therefore, the longer the time is used, the more bacteria there are inside the washing machine, which can easily lead to secondary pollution when users use the washing machine.

[0003] The Chinese patent application number 201720475317.X discloses a washing machine drum cleaning system and a washing machine, including a spray device, which is arranged on the outer wall of the inner drum of the washing machine drum to spray water to a set area of ​​the drum; wherein, when the water inlet of the spray device rotates with the inner drum to the water storage area of ​​the drum, the water in the water storage area can enter the spray device from the water inlet. This application mainly uses the drum for spray cleaning, which can simplify the structure of the washing machine and reduce costs. However, the rapid flushing method cannot remove the deposited dirt, has a weak cleaning power for the deposited stains, and does not have a sterilizing effect; the high water level washing and cleaning method, although it increases the water and electricity consumption, has a limited drum cleaning effect and cannot effectively clean the stains between the inner and outer drums, especially the middle of the drum and the tripod support part.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a washing equipment drum cleaning device and a cleaning method. By installing a pressurized flushing component on the inner wall of the outer drum of the washing machine and arranging multi-angle flushing nozzles on the pressurized cleaning component, pressurized water is used to clean different positions of the drum wall, which can make it easier to clean stains and reduce cleaning time.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0007] A first aspect of the present invention provides a drum cleaning device for a washing machine, comprising:

[0008] A pressurized flushing assembly is arranged on the inner wall of the outer drum of the washing equipment; the pressurized flushing assembly comprises a water inlet pipeline and a pressurized pipeline, and the diameter of the pressurized pipeline is smaller than the diameter of the water inlet pipeline;

[0009] The pressurized flushing assembly also includes at least two groups of flushing nozzles, which are arranged on the pressurized pipeline, at least one group sprays water toward between the inner and outer cylinders, and at least one group sprays water toward the front end opening of the inner cylinder.

[0010] In the above scheme, since the flow rate is proportional to the flow velocity and the cross-sectional area of ​​the pipe through which the fluid passes, that is, flow rate = pipe cross-sectional area * flow velocity, when the flow rate is constant, by reducing the cross-sectional area of ​​the pipe through which the fluid passes, the flow velocity of the fluid per unit time is increased under the same fluid volume, thereby achieving the effect of pressurizing the fluid.

[0011] In the above scheme, by setting up multiple groups of flushing nozzles at different angles, the cleaning water can be sprayed at multiple angles and directions, so that the cleaning water can cover the entire area between the inner and outer cylinders, thereby achieving thorough cleaning between the inner and outer barrels.

[0012] Furthermore, the pressurized pipeline includes a first pressurized pipeline and a second pressurized pipeline, and the first pressurized pipeline is connected to the second pressurized pipeline in a switching manner in the axial direction.

[0013] In the above scheme, the second pressurized pipeline is arranged in a different direction from the first pressurized pipeline, and a certain angle is set between the two, so as to achieve the effect of guiding the cleaning water to different directions.

[0014] Furthermore, one end of the first pressurizing pipeline is connected to the water inlet pipeline, and the other end is connected to the second pressurizing pipeline; water in the water inlet pipeline enters the second pressurizing pipeline after being pressurized by the first pressurizing pipeline.

[0015] Furthermore, the flushing nozzle is arranged on a side of the second pressurized pipeline facing away from the first pressurized pipeline, and a cross-sectional area of ​​the flushing nozzle is smaller than a cross-sectional area of ​​the first pressurized pipeline.

[0016] In the above scheme, the water in the pipeline is reversed by the second pressurized pipeline and then passed into different flushing nozzles, and then sprayed between the inner and outer cylinders through the flushing nozzles to clean the stains on the inner and outer cylinders. The total cross-sectional area of ​​the flushing nozzles is smaller than the cross-sectional area of ​​the first pressurized pipeline, which plays a role of secondary pressurization of the cleaning water.

[0017] Furthermore, the flushing nozzle is a flat nozzle for forming fan-shaped spraying surfaces of different angles.

[0018] In the above scheme, the shape of the liquid sprayed by the flat nozzle is like a fan. According to the size of the nozzle opening, fan-shaped surfaces with different angles can be generated, thereby increasing the coverage area of ​​the sprayed cleaning water.

[0019] Furthermore, the cleaning device of the washing equipment also includes: an electromagnetic water valve, and the electromagnetic water valve is connected to the pressurized flushing component through a water pipe.

[0020] In the above scheme, the electromagnetic water valve provides a separate water circuit on-off control for the pressurized flushing component. When the pressurized flushing component needs to be used, the electromagnetic water valve is opened to supply water to it to achieve cleaning of the inner and outer cylinders.

[0021] A second aspect of the present invention provides a drum cleaning method for a washing device, comprising:

[0022] S1, obtaining a signal for starting the drum cleaning;

[0023] S2, setting the soaking water temperature WT1 and soaking time T1 of the drum;

[0024] S3, execute the soaking procedure according to the set WT1 and T1;

[0025] S4, setting the washing water temperature WT2 and washing time T2 of the drum;

[0026] Among them, WT2>WT1;

[0027] S5, according to the set WT2 and T2, execute the washing program and the pressure flushing program;

[0028] S6, after the washing process is completed, the rinsing process and the pressure washing process are performed;

[0029] S7, the barrel cleaning program ends.

[0030] Optionally, in S3, the immersion procedure includes:

[0031] S31, opening the water inlet valve of the washing equipment, and after the water reaches a first set water level, closing the water inlet valve;

[0032] S32, heating the water in the drum to the soaking water temperature WT1, executing the soaking procedure, and the soaking time is t1;

[0033] S33, rotating the drum to a certain angle, continuing the soaking procedure, the soaking time is t2;

[0034] S34, after reaching the soaking time T1, the soaking procedure ends;

[0035] Among them, t1+t2=T1.

[0036] In S5, the washing procedure includes:

[0037] S51, open the water inlet valve, add water to the second set water level, and then close the water inlet valve;

[0038] S52, heating the water in the drum to the washing water temperature WT2, and maintaining a stable temperature during the washing stage;

[0039] S53, while executing the washing procedure, turning on the cleaning device to perform a pressurized flushing procedure;

[0040] S54, after reaching the soaking time T1, the soaking process ends;

[0041] S55, when the washing time T2 is reached, the washing process ends and the water in the drum is drained; wherein T2>T1.

[0042] In S6, the rinsing procedure includes:

[0043] S61, open the water inlet valve, and after the water enters to the third set water level, close the water inlet valve;

[0044] S62, start the rinsing level and pressure washing program;

[0045] S63. After the rinsing time is reached, the rinsing process and the pressurized flushing procedure are terminated, and the water in the barrel is drained. After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. The present invention realizes the pressurization of clean water by changing the diameter of the pipeline, and does not set up redundant devices. Compared with adding a pressurizing device, the flushing device has a simple structure and improves the cleaning effect of the deposited materials in the barrel; the present invention sets a multi-angle flushing nozzle on the pipeline, so that the cleaning water can be sprayed from the cleaning nozzle at multiple angles and directions, so that the cleaning water can cover the entire area between the inner and outer barrels, and achieve thorough cleaning between the inner and outer barrels; compared with the high-water-level immersion mode, the present invention adopts a low-frequency rotation method to realize the immersion of the barrel. The washing procedure and the rinsing procedure after the immersion are combined with pressurized flushing, which can save more water and electricity; the present invention performs parameter adaptive adjustment of the immersion, washing and rinsing time according to the different detergents in the barrel, which can reduce the risk of unclean rinsing and improve the reliability of the barrel cleaning process.

DETAILED DESCRIPTION

[0056] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0057] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0058] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0059] In a first aspect of the present invention, there is provided a drum cleaning device for a washing machine, such as Figure 1 to Figure 2 shown.

[0060] Furthermore, the pressurized flushing assembly 1 is arranged on the inner wall of the outer drum 2 of the washing equipment, and the pressurized flushing assembly 1 includes a water inlet pipeline 11 and a pressurized pipeline 12 , and the diameter of the pressurized pipeline 12 is smaller than the diameter of the water inlet pipeline 11 .

[0061] Furthermore, the pressurizing component also includes at least two groups of flushing nozzles 13, which are arranged on the pressurizing pipeline 12, at least one group sprays water toward between the inner and outer cylinders, and at least one group sprays water toward the front end opening of the inner cylinder.

[0062] Specifically, the pressurized flushing component 1 is arranged on the inner wall above the outer drum 2 between the inner drum 3 and the outer drum 2 of the washing equipment, and flushing nozzles 13 in different directions are arranged on the pressurized pipeline 12, so that the flushing angle of the pressurized flushing component 1 can cover the entire upper half of the inner drum 3, ensuring that the cleaning effect of the entire outer wall of the inner drum 3 and the inner wall of the outer drum 2 is improved during the cleaning process.

[0063] Specifically, the pressure of the cleaning water is increased by reducing the diameter of the pipeline. The principle is based on the formula Q=SV, which is the relationship between the flow rate, the flow velocity and the area of ​​the cross section through which the fluid passes. 3 / h); S—cross-sectional area (m 2 ); V—average velocity of the fluid (m / s); S represents the area of ​​the cross section, and according to the calculation of the area of ​​a circle, it can be known that the size of the area is proportional to the radius. Therefore, when the flow rate in the water inlet pipeline 11 per unit time is consistent, compared with the radius of the water supply pipeline, by reducing the radius of the pressurized pipeline 12, the cross-sectional area through which the fluid flows is reduced, and the liquid flow rate per unit time under the same fluid volume is increased, thereby achieving a pressurized flushing effect.

[0064] Furthermore, the pressurizing pipeline 12 includes a first pressurizing pipeline 121 and a second pressurizing pipeline 122 , and the first pressurizing pipeline 121 and the second pressurizing pipeline 122 are connected in a switching manner in the axial direction.

[0065] Specifically, the first pressurized pipeline 121 and the second pressurized pipeline 122 form a three-way connection, with a certain angle between the two, and the shape is similar to the letter "T". In this connection, the connection between the first pressurized pipeline 121 and the second pressurized pipeline 122 forms a certain angle, which can guide the water in the first pressurized pipeline 121 to different directions, increasing the coverage of the water.

[0066] Furthermore, one end of the first pressurized pipeline 121 is connected to the water inlet pipeline 11 , and the other end is connected to the second pressurized pipeline 122 ; water in the water inlet pipeline 11 enters the second pressurized pipeline 122 after passing through the first pressurized pipeline 121 .

[0067] Specifically, the caliber of the water inlet pipeline 11 is larger than the caliber of the first pressurized pipeline 121, so the water inlet pipeline 11 is sleeved on the first pressurized pipeline 121; the first pressurized pipeline 121 and the second pressurized pipeline 122 are connected together by welding. When the pressurized flushing assembly 1 is needed, water enters from the water inlet pipeline 11, then flows to the first pressurized pipeline 121, and after being pressurized by the first pressurized pipeline 121, it enters the second pressurized pipeline 122 through the connection between the first pressurized pipeline 121 and the second pressurized pipeline 122, and is dispersed to different directions.

[0068] Furthermore, the flushing nozzle 13 is disposed on a side of the second pressurized pipeline 122 facing away from the first pressurized pipeline 121 , and a cross-sectional area of ​​the flushing nozzle 13 is smaller than a cross-sectional area of ​​the first pressurized pipeline 121 .

[0069] Furthermore, the flushing nozzle 13 is a flat nozzle for forming fan-shaped spraying surfaces at different angles.

[0070] Specifically, a flushing nozzle 13 is provided on the side of the second pressurized pipeline 122 facing away from the first pressurized pipeline 121, and a plurality of flushing nozzles 13 can be provided according to the requirements of the total spraying area and orientation to cover more outer walls of the inner cylinder 3. All nozzles are provided as flat nozzles, which not only reduces the cross-sectional area of ​​the spraying outlet, but also forms different fan-shaped spraying surfaces of the sprayed water, which can cover a larger area of ​​the cylinder wall and improve the cleaning effect of the entire inner cylinder 3 and the outer cylinder 2 cylinder wall.

[0071] Preferably, the first pressurizing pipeline 121, the second pressurizing pipeline 122 and the flushing nozzle 13 are integrally injection molded, which has a simple manufacturing process and can prevent water leakage due to an increase in water pressure.

[0072] Furthermore, the drum cleaning device also includes an electromagnetic water valve, and the electromagnetic water valve is connected to the pressurized flushing assembly 1 through a water pipe.

[0073] Specifically, when it is necessary to use the pressurized flushing component to clean the drum, open the electromagnetic water valve. At this time, a part of the water enters the water inlet pipe 11 of the pressurized flushing component 1 through the water pipe connected between the electromagnetic water valve and the pressurized flushing component 1, and then enters the pressurized pipe 12 through the water inlet pipe 11. After being pressurized in the first pressurized pipe 121, it enters the second pressurized pipe 122 to achieve the reversal of water flow, and finally enters the flushing nozzle 13, and is sprayed out from the flushing nozzle 13 to form a fan-shaped spray surface to clean the drum wall.

[0074] A second aspect of the present invention provides a method for cleaning a washing machine, such as Figure 3 As shown, it includes steps S1 to S7.

[0075] In step S1 , a drum cleaning start signal is acquired.

[0076] Specifically, optionally, a time for drum self-cleaning is set on the washing device itself, and when the drum self-cleaning time is reached, the washing device reminds the user to clean the drum; optionally, the dirtiness of the drum of the washing device is detected, and when it is determined through detection that the washing device needs to clean the drum, the user is reminded to clean the drum, and after receiving the reminder, the user starts the drum cleaning program, thereby obtaining a signal for starting the drum cleaning.

[0077] In step S2, the soaking water temperature WT1 and the soaking time T1 of the drum are set.

[0078] Specifically, different soaking water temperatures and soaking times are set according to different detergents added, thereby obtaining different soaking procedures. At the same time, a low-frequency, small-angle rotation method is adopted to achieve full infiltration and soaking of the cylinder wall under low water level conditions.

[0079] Advantageously, setting different soaking water temperatures and soaking times according to different detergent types helps the drum detergent to melt, disperse and act quickly.

[0080] In step S3, according to the set WT1 and T1, the soaking process is performed.

[0081] Specific immersion procedures, such as Figure 4 As shown, steps S31 to S34 are included.

[0082] In step S31, the water inlet valve of the washing machine is opened, and after the water reaches a first set water level, the water inlet valve is closed.

[0083] In step S32, the water in the drum is heated to the soaking water temperature WT1, and the soaking procedure is performed, and the soaking time is t1.

[0084] In step S33, the drum is rotated by a certain angle and the soaking procedure is continued, and the soaking time is t2.

[0085] In step S34, after reaching the soaking time T1, the soaking process ends; wherein, t1+t2=T1.

[0086] Specifically, different soaking temperatures and soaking times are formulated according to different types of detergents, thereby obtaining different soaking programs. During the soaking program, the drum of the washing equipment rotates at a speed of 40-90rpm, the washing temperature can be set at 20-60℃, and the soaking time can be set at 10-60min. This setting helps the drum detergent to melt, disperse and act quickly, and can achieve full infiltration and soaking of the drum wall under low water level conditions.

[0087] In this embodiment, the need for drum cleaning is first obtained, and then a suitable drum cleaner is added. According to the selected drum cleaner, the water temperature of the soaking water and the time for the soaking program are set. For example, if the type of the drum cleaner is liquid and needs to be soaked, the water level of the soaking water is set at 5-20cm, the soaking speed is set to 40-90rpm, the soaking degree is set to rotate for 5s and stop for 15s, the soaking time is set to 2-10min, and the water temperature is set to 20-40℃. After the setting is completed, the washing equipment performs the soaking program according to the set parameters. First, washing water is added to the drum to make the washing water level reach the set soaking water level of 5-20cm, and then the water in the drum is heated to keep the water temperature at the set soaking water temperature of 20-40℃. Then the washing equipment drum starts to perform the soaking program according to the soaking timing of rotating for 5s and stopping for 15 seconds, and ensures that the rotation speed is 40-90rpm, and the soaking program is performed according to the set time.

[0088] In this embodiment, in addition to the above-mentioned drum cleaning agents that require soaking, there are also drum cleaning agents that do not require soaking. In this case, the soaking procedure can be directly ignored and the corresponding washing procedure can be directly executed.

[0089] In step S4, the washing water temperature WT2 and the washing time T2 of the drum are set;

[0090] Among them, WT2>WT1.

[0091] Specifically, after the soaking program is finished, the water temperature and washing time during the drum washing are set according to the type of drum detergent previously selected.

[0092] In step S5, the washing process and the pressure-rinsing process are performed according to the set WT2 and T2.

[0093] Specifically, different washing water temperatures and washing times are set according to different detergents, and a pressurized flushing program is used to achieve powerful cleaning of stains in the drum.

[0094] Optionally, the washing program is performed as follows Figure 5 Steps S51 to S55 are shown.

[0095] In step S51, the water inlet valve is opened, and after the water is replenished to a second set water level, the water inlet valve is closed.

[0096] In step S52, the water in the drum is heated to the washing water temperature WT2, and the temperature is maintained stable during the washing phase.

[0097] In step S53, while executing the washing program, the cleaning device is turned on to perform a pressurized flushing program.

[0098] In step S54, after the soaking time T1 is reached, the soaking process ends.

[0099] In step S55, when the washing time T2 is reached, the washing process ends and the water in the drum is drained; wherein, T2>T1.

[0100] Specifically, various parameters required for the washing program are set according to the drum detergent added during soaking, and then the washing program is executed.

[0101] In this embodiment, the water inlet valve is first opened to replenish water into the drum, and the replenished water level reaches the water level set for the washing program. The water in the drum is then heated to meet the water temperature during drum washing, and the water temperature is kept stable, and then the washing program is started.

[0102] Specifically, for example, according to the above-mentioned type of added drum detergent is liquid and requires soaking, the water level height when executing the soaking program is 5-20cm, and when executing the washing program, water needs to be added to the drum to raise the water level by 30-50cm; the washing speed when executing the soaking program is 40-90rpm, and when executing the washing program, the speed of the drum is set to 45rpm; when executing the soaking program, the drum rotates for 5s and stops for 15s, and when executing the washing program, in order to better clean the stains on the drum, the drum rotates for 12s and stops for 4s; the washing time is 30-50min, which is greater than the soaking time, and then the washing program is executed.

[0103] It should be noted that when the drum is cleaned, the washing program and the soaking program are executed together. The soaking program is also executed during the washing program. When the soaking program time is reached, the soaking program will no longer be executed and only the washing program will be executed.

[0104] Specifically, when executing the washing program, the water temperature of the washing water is also higher than the water temperature during soaking, so as to better clean the stains on the drum wall. As mentioned above, if the type of drum cleaner used is liquid and soaking is required, the water temperature during washing is set to 40-60°C; if a non-soaking drum cleaner is used, the parameter setting of the washing program is also the same, using a high water level and high speed washing method to achieve strong cleaning of the stains in the drum. .

[0105] Optionally, a pressurized flushing program is performed while executing the washing program.

[0106] Specifically, the electromagnetic water valve of the cleaning device is opened, and the cleaning water enters the pressurized flushing component 1 through the electromagnetic water valve and the water inlet pipe 11 of the pressurized flushing component 1, and then increases the water pressure through the pressurized pipe 12, and then enters the cleaning nozzle. The flat nozzle pressurizes the cleaning water again, and the fan-shaped spray surface at the spray point increases the cleaning water pressure while increasing the cleaning area of ​​the cylinder wall.

[0107] In step S6, after the washing process is completed, a rinsing process and a pressure washing process are performed.

[0108] Optionally, the rinsing procedure is as follows Figure 6 As shown, execute steps S61 to S63.

[0109] In step S61, the water inlet valve is opened, and after the water reaches the third set water level, the water inlet valve is closed;

[0110] In step S62, the rinse level and pressure flushing program are turned on;

[0111] In step S63, after the rinsing time is reached, the rinsing process and the pressurized flushing program are ended and the water in the drum is drained.

[0112] Specifically, on the basis of the above-mentioned washing procedure, after the washing procedure is completed, the washing water in the drum is drained, and then the water valve is opened, and water is added to the drum to the water level of the rinsing procedure to rinse the drum. The rinsing water level is set to 40-60cm, and the speed of the drum during rinsing is increased to 80rpm, the rinsing time is set to 25min, and the water is not heated. While rinsing, a pressurized flushing procedure is performed. Through the rinsing procedure and the pressurized flushing procedure, the stains on the drum wall are continuously flushed to achieve the effect of cleaning the drum wall.

[0113] In this embodiment, the user cleans the drum regularly according to the drum cleaning time set on the washing device or detects the dirtiness of the drum through the detection device and needs to be cleaned. Add a drum cleaner into the drum, then turn on the water inlet device of the washing device, fill the drum with water, and stop filling water after reaching the soaking program water level. Heat the water in the drum to make the water temperature reach the soaking water temperature, then execute the soaking program, and after reaching the soaking time, empty the water in the drum and refill the drum with water.

[0114] Specifically, after the water injected into the drum reaches the washing water level, the water in the drum is heated so that the water temperature reaches the temperature required for the washing program and the temperature is kept stable. At the same time, the pressurized flushing device is turned on and the solenoid valve is opened to supply water to the pressurized flushing component. While executing the washing program, the pressurized flushing program is executed to achieve the effect of quickly cleaning the drum wall.

[0115] Specifically, after washing is completed, the water in the drum is drained, and water is refilled into the drum to the rinsing water level, and then the drum is rinsed, and a pressurized flushing program is performed at the same time to achieve faster and more efficient cleaning of the drum wall.

[0116] In this embodiment, the washing equipment sets corresponding soaking programs, washing programs and rinsing programs according to the types of different drum detergents, and combines the cleaning device of the washing equipment to perform pressurized flushing of the drum wall, which saves more electricity and water, and at the same time can improve the cleaning efficiency and cleaning effect of the drum.
