Description

Technical Field

[0001] This invention belongs to the field of washing equipment technology, specifically relating to an automatic detergent dispensing device, a clothes washing device, and an automatic detergent dispensing method. Background Technology

[0002] During the use of a washing machine, after putting in the clothes to be washed, the amount of detergent is mainly added manually. Users cannot accurately judge the amount of detergent to add based on the amount of clothes. As a result, after the washing process is completed, if too little detergent is added, the washing effect of the clothes will be poor, or if too much detergent is added, the detergent residue after rinsing and spinning will not meet the standards. Summary of the Invention

[0003] In view of the above-mentioned technical problems existing in the washing machine of the prior art when washing clothes, the present invention proposes an automatic detergent dispensing device, which can drive the device to rotate, so that the material scraping device can be activated to drop the detergent located in the storage component into several sub-storage compartments in the dispensing component below, so as to realize the quantitative addition of detergent.

[0053] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0054] It should be noted that in the description of this invention, the terms "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0055] This invention proposes an embodiment of an automatic detergent dispensing device, comprising:

[0056] A storage component 100 has a storage cavity 110 formed inside it, and a first dispensing part 120 is provided at the bottom of the storage cavity 110.

[0057] In some embodiments, the storage component 100 is a storage box, and the storage cavity 110 formed inside it is used to store detergent.

[0058] The first dispensing section 120 is a first dispensing port located on the bottom of the storage box. The shape of the first dispensing port can be fan-shaped, rectangular, etc., and there are no specific restrictions here.

[0059] A material scraping component 200 is disposed in the storage cavity 110 to guide the material in the storage cavity 110 to the first dispensing part 120;

[0060] A dispensing component 300 is disposed below the storage component 100, and a second dispensing part 310 is disposed below the dispensing component 300. The second dispensing part 310 is staggered from the first dispensing part 120.

[0061] The dispensing component 300 is used to receive detergent dispensed from the first dispensing port, and the second dispensing part 310 is a second dispensing port used to dispense detergent from the dispensing component 300.

[0062] To prevent detergent in storage component 100 from being dispensed directly into second dispensing port through first dispensing port, thus failing to achieve accurate dispensing, second dispensing unit 310 and first dispensing unit 120 are arranged in a staggered manner so that detergent falling from first dispensing port will not directly enter second dispensing unit 310.

[0063] In some embodiments of this application, the first dispensing part 120 and the second dispensing part 310 are arranged at 180-degree angle intervals or at 90-degree angle intervals.

[0064] Alternatively, the first delivery part 120 can be positioned so that its projection on the delivery component 300 is adjacent to the second delivery part 310, as long as the first delivery part 120 and the second delivery part 310 are staggered. No specific restrictions are imposed here.

[0065] A partition component 400 is disposed inside the delivery component 300 and divides it into multiple independent sub-storage compartments 320.

[0066] The bottom walls of multiple sub-storage compartments 320 and storage components 100 are adjacent to and form multiple closed storage cavities with the storage components 100;

[0067] When the delivery component 300 is installed, its top opening abuts against the bottom wall of the storage component 100, so that multiple closed storage compartments can be formed between the multiple sub-storage compartments 320 formed by the partition component 400 and the storage component 100.

[0068] Specifically, multiple partition components 400 are provided and arranged along the radial direction of the dispensing component 300. One end of each partition component 400 intersects, and the other end is connected to the inner peripheral sidewall of the dispensing component 300.

[0069] The sub-storage compartment 320 is formed by enclosing the bottom walls of two adjacent partition components 400 and delivery components 300;

[0070] The sub-storage compartments 320 are arranged sequentially adjacent to each other along the circumference of the delivery component 300.

[0071] The second dispensing section 310 is a fan-shaped dispensing port arranged radially along the dispensing component 300, and the cross-sectional area of ​​the fan-shaped dispensing port is greater than or equal to the cross-sectional area of ​​the sub-storage compartment 320.

[0072] A drive device 500 is connected to the material scraping component 200 and the partition component 400 to drive the material scraping component 200 and the partition component 400 to rotate.

[0073] The first inlet is located on the rotation path of the material scraping component 200 to ensure that the material scraping component 200 can push the material in the storage cavity 110 into the first inlet position when it rotates.

[0074] The second dispensing port is located on the rotating channel of the sub-storage compartment 320 to ensure that the detergent stored in the sub-storage compartment 320 can be dispensed through the second dispensing port.

[0075] The drive device 500 drives the material scraping component 200 to rotate, so that when it rotates, it can continuously scrape the detergent located in the storage cavity 110 into the first dispensing part 120 to achieve the effect of dispensing detergent into the dispensing component 300.

[0076] The partition component 400 is rotated by the drive device 500. When the partition component 400 rotates, the detergent stored in the storage compartment 320 is pushed to the corresponding position of the second dispensing port so as to dispense the detergent into the washing machine.

[0077] In some embodiments of this application, the driving device 500 is a drive motor, which includes a transmission shaft 510. The transmission shaft 510 extends along the height direction of the storage component 100 and the dispensing component 300, and is connected in sequence to the material scraping component 200 and the partition component 400.

[0078] In this embodiment, the automatic detergent dispensing device separates the detergent storage and dispensing functions. The storage component 100, located at the top, stores the detergent, while the dispensing component 300 ensures precise detergent dispensing.

[0079] The drive unit 500 rotates, causing the material scraping component 200 to rotate. When the material scraping component 200 rotates, it can scrape the detergent stored in the storage component 100 into the first dispensing part 120. At the same time, since the drive unit 500 is also connected to the partition component 400, when the drive motor rotates, it can also drive the partition component 400 to rotate, so that the separate storage compartment 320 formed by the partition component 400 and the dispensing component 300 can be filled with detergent in sequence through the first dispensing part 120.

[0080] When using the washing machine, users can estimate the amount of detergent needed based on the amount of laundry. For example, if there are about 5 pieces of laundry, 20ml of detergent is needed to initially determine the required amount. Then, based on the required amount of detergent, the user controls the drive device 500 to rotate. The material scraping component 200 feeds the material from the storage component 100 into the sub-storage compartment 320 through the first dispensing part 120. At the same time, the sub-storage compartment 320 also rotates continuously and is continuously filled.

[0081] When set up, multiple storage compartments 320 can store the same amount of detergent. For example, each storage compartment 320 can store 10ml, and the amount of detergent used is 20ml. In this case, two storage compartments 320 need to be dispensed through the second dispensing unit 310.

[0082] The angle that the motor needs to rotate corresponds to the angle value of each sub-storage compartment 320 multiplied by the number of sub-storage compartments 320 that need to pass through the second delivery section 310.

[0083] To ensure that in this embodiment, after the automatic detergent dispensing device rotates the drive motor to the required angle, two separate storage compartments 320 will pass through the second dispensing section 310 to dispense 20ml of detergent, the following settings are configured:

[0084] The area between the second delivery section 310 and the sub-storage compartment 320 corresponding to the location of the first delivery section 120 is divided into a first storage compartment area and a second storage compartment area located on both sides. The first storage compartment area includes a plurality of sub-storage compartments 320, and the second storage compartment area also includes a plurality of sub-storage compartments 320.

[0085] When the drive unit 500 rotates, it reaches the sub-storage compartment 320 in the storage compartment area of ​​the second delivery unit 310 before the sub-storage compartment corresponding to the position of the first delivery unit 120, so that the sub-storage compartment is in a fully loaded state.

[0086] In this way, when the drive device 500 rotates, the fully loaded sub-storage compartment 320 is first dispensed by the second dispensing section 310. After the fully loaded sub-storage compartment 320 is dispensed, the empty sub-storage compartment 320 is also filled with detergent in turn, ensuring the normal and accurate dispensing of detergent.

[0087] In some embodiments of this application, the drive device 500 includes a drive shaft 510, and the partition component 400 is a partition plate, and multiple partition plates are provided, with the multiple partition plates fixedly connected to the drive shaft 510.

[0088] The dividing plates are evenly arranged along the circumference of the drive shaft 510, and the material of the dividing plates can be plastic parts.

[0089] When set up, the top of the partition component 400 is adjacent to the bottom wall of the storage component 100, and the bottom of the partition component 400 is adjacent to the bottom wall of the dispensing component 300, so that the sub-storage compartments 320 formed between the partition component 400, the storage component 100, and the dispensing component 300 can be relatively closed, preventing detergent from flowing between the sub-storage compartments 320 and affecting the accuracy of quantitative addition.

[0090] In some embodiments of this application, the material scraping component 200 includes at least two material scraping blades 210, which are fixedly connected to the drive shaft and disposed perpendicular to the bottom wall of the storage component 100.

[0091] The material scraping blades 210 are arranged on the side wall of the vertical drive shaft 510. In some embodiments, in order to achieve a large pushing effect on the detergent, the two material scraping blades 210 can be arranged at a 180-degree angle or at an acute angle.

[0092] Of course, multiple material scraping blades 210 can be set up and evenly arranged along the circumference of the drive shaft 510, forming a scraping space between adjacent material scraping blades 210.

[0093] In some embodiments of this application, the height of the material scraping blade 210 is at least 3 / 4 of the height of the storage component 100.

[0094] To ensure that the material scraping blade 210 can deliver a large amount of material from the first dispensing section 120 into the storage unit 100, so that the sub-storage bin 320 below it will be instantly filled when it passes through the first dispensing port, the material scraping blade 210 should be set to a relatively high height. Preferably, the height of the material scraping blade 210 is the same as the height of the storage unit 100.

[0095] In some embodiments of this application, the cross-sectional area of ​​the first dispensing port is larger than the cross-sectional area of ​​the second dispensing port.

[0096] The cross-sectional area of ​​the first dispensing port is set to be larger than that of the second dispensing port, mainly to ensure that the detergent falling from the first dispensing port can quickly and in large quantities fall into the sub-storage compartment 320 to fill the sub-storage compartment 320.

[0097] In some embodiments of this application, in order to ensure that the storage component 100 stores sufficient detergent dosage to ensure that the storage chamber 320 can be quickly filled when the material scraping component 200 rotates, the detergent dosage liquid level in the storage component 100 should not be lower than 1 / 2 of the height of the storage component 100.

[0098] Example 2:

[0099] The present invention also proposes an embodiment of a clothing washing device, including the detergent dispensing device in Embodiment 1. The clothing washing device includes a housing 700 and a tub 600 disposed inside the housing 700. A washing space is formed inside the tub 600, and a foot is provided below the housing 700.

[0100] A tray is installed at the top opening of the tub body 600, and an automatic detergent dispensing device is installed on the tray.

[0101] The laundry appliance also includes:

[0102] A weight detection element is installed inside the laundry washing device to weigh the clothes to be washed;

[0103] The weight detection element is a weight detection sensor, which can be installed at the bottom of the laundry washing device.

[0104] A water level detection element, used to detect the washing water level, is installed inside the tub 600. The water level detection element can be a water level sensor.

[0105] Water temperature sensing element, used to detect the water temperature inside the drum of a laundry washing machine;

[0106] The water temperature sensing element can be built into the bottom wall of the tub 600 to detect the actual water temperature used by the user during washing.

[0107] The controller is communicatively connected to the weight detection element, water level detection element, water temperature detection element, and drive device 500.

[0108] In this embodiment, when the user puts the clothes to be washed into the tub 600, the initial weight of the clothes can be obtained through the weight detection element and the initial weight information of the clothes can be transmitted to the controller.

[0109] Meanwhile, the water level detection element can obtain the actual water consumption used by the user for washing, and the water temperature detection element can obtain the actual water temperature value used by the user for washing. The water temperature detection element and the water level detection element will transmit the detected water temperature information and water level information to the controller.

[0110] An automatic detergent dispensing method for a laundry washing apparatus according to the above embodiments includes the following steps:

[0111] Obtain the initial weight of the clothes to be washed in the washing machine, and determine the corresponding baseline amount of detergent based on the initial weight;

[0112] Determining the baseline detergent dosage based on the initial weight includes:

[0113] Obtain the correspondence between the preset weight range of clothes and the benchmark dosage of detergent;

[0114] The baseline dosage of detergent corresponding to the initial weight is determined based on the aforementioned correspondence.

[0115] The controller can pre-store clothing weight ranges and the corresponding baseline delivery amount for each range.

[0116] Based on which weight range the detected clothing falls into, determine the baseline detergent dosage corresponding to the initial weight of the clothing.

[0117] Acquire the user's washing mode, preset washing water temperature, actual water temperature, and the reference water level and actual water level corresponding to the user's washing mode;

[0118] The user's washing machine mode refers to the washing mode provided by the washing device, such as high-intensity wash or gentle wash.

[0119] The preset washing water temperature is a reference water temperature value pre-stored in the controller.

[0120] The actual water temperature is the water temperature value inside the tank 600 obtained through the water temperature detection element;

[0121] The reference water temperature is the water level pre-stored in the controller for the corresponding washing machine mode.

[0122] The actual water level is the water level inside the tank 600 detected by the water level detection element.

[0123] Since users may sometimes set the water level individually according to their actual needs when selecting a user washing mode, it is necessary to detect the actual water level inside the tub 600.

[0124] The initial revised detergent dosage is obtained based on the washing mode revision parameters corresponding to the user's washing machine mode and the baseline dosage.

[0125] The washing mode revision parameters are obtained from the washing mode revision parameter table pre-stored in the controller.

[0126] Different washing modes have different corresponding washing mode revision parameters. The washing mode revision parameter is 'a'.

[0127] When a user selects the standard washing mode, the corresponding washing mode revision parameter is 1.

[0128] The initial revised delivery amount is the product of the washing mode revision parameter corresponding to the user's washing machine mode and the baseline delivery amount; that is, the initial revised delivery amount m2 = am1.

[0129] The water level revision parameters are derived from the baseline water level and the actual water level of the user's washing mode, and the secondary revised detergent dosage is obtained from the initial revised dosage.

[0130] The second revised dosage is the product of the water temperature revision parameter and the initial revised dosage.

[0131] That is, the amount of the second revision is m3 = bm2

[0132] Among them, water level revision parameter b.

[0133] The water level revision parameters are obtained based on the ratio of the reference water level to the actual water level.

[0134] When the actual water level and the reference water level are detected to be the same, that is, the user has not set a separate water level, the water level revision parameter is 1.

[0135] The actual amount of detergent to be added is obtained by revising the water temperature parameters based on the preset washing water temperature and the actual water temperature, and then revising the dosage a second time.

[0136] In some embodiments of this application, the automatic detergent dispensing method of the laundry washing device...

[0137] The water temperature revision parameter is obtained using the following formula:

[0138] c = 1 - (T) 实际 -T 预设 ) / 3 T 预设;

[0139] Where c is the water temperature revision parameter, T 实际 Actual water temperature ， T 预设 The preset washing water temperature is 0.5°C < 2°C.

[0140] The actual amount of detergent added is the product of the water temperature revision parameter and the second revised addition amount.

[0141] The actual amount of detergent added is m4 = cm3.

[0142] When the actual water temperature and the preset washing water temperature are detected to be within the preset water temperature range, that is, when the water temperature revision parameter is 1, the actual amount of detergent added is the same as the amount added in the second revision.

[0143] Based on the actual amount of detergent added, the rotation angle of the drive device 500 is obtained, and the drive device 500 is controlled to drive the storage component 100 to rotate to the specified angle.

[0144] In the step of obtaining the rotation angle of the drive device by 500° based on the actual amount of detergent added,

[0145] Among the multiple sub-storage compartments 320 of the dispensing component 300, the sub-storage compartment 320 in the area corresponding to the position of the first dispensing part 120 is in a full-load state. Since the first dispensing part 120 is normally open in this embodiment, the detergent stored in the storage component 100 and one or more sub-storage compartments 320 corresponding to the position of the first dispensing part 120 will be filled with detergent. Furthermore, since the remaining sub-storage compartments 320 located around it form a closed storage cavity with the bottom wall of the storage component 100, the detergent will not continue to flow down into the remaining sub-storage compartments 320, thereby keeping the filled storage compartments in a full state.

[0146] To ensure the accuracy of detergent dosage, during setup, a first storage area and a second storage area are formed between the second dispensing section 310 and the sub-storage compartment 320 located in the area corresponding to the first dispensing section 120. The first storage area includes multiple sub-storage compartments 320, and the second storage area also includes multiple sub-storage compartments 320.

[0147] When the drive unit 500 rotates, it first reaches the sub-storage compartment 320 in the storage compartment area of ​​the second delivery unit 310 before the sub-storage compartment corresponding to the position of the first delivery unit 120, and sets it to a full-load state.

[0148] In specific settings, the opening of the first delivery section 120 can be enlarged to fill the sub-storage compartments in this storage compartment 320 area, or the drive device 500 can be rotated to pre-fill them; no specific restrictions are imposed here.

[0149] For ease of description, this embodiment uses an example with 7 sub-storage compartments 320, one of which is the second delivery unit 310.

[0150] Assume that the top storage compartment 320, located at the very top, is filled by the first delivery unit 120.

[0151] The sub-storage compartments 320 located on the right side between the top storage compartment and the second delivery compartment 310 are the first sub-storage compartment 321, the second sub-storage compartment 322, and the third sub-storage compartment 323, respectively. The drive device 500 rotates clockwise, so this part is fully loaded. The fourth sub-storage compartment 324, the fifth sub-storage compartment 325, and the sixth sub-storage compartment 326 located on the left side are empty.

[0152] If the drive unit 500 rotates counterclockwise, the sub-storage compartment 320 located on the left side is fully loaded, while the sub-storage compartment 320 located on the right side is empty.

[0153] After calculating the actual amount of detergent needed, the data is transmitted to the controller. The controller calculates the required rotation angle of the drive unit 500 based on the amount of detergent needed. For example, if 40ml of detergent is needed, and each storage compartment 320 is filled with 10ml of detergent, it needs to pass through 4 full storage compartments 320. Since there are 7 storage compartments 320, each storage compartment 320 corresponds to an angle of 45 degrees. The 4 drive units 500 need to rotate 180 degrees. At this time, the drive units 500 can rotate 180 degrees. Since the top storage compartments 320 of the first, second, and third storage compartments on the right are not full, the first dispensing part 120 does not dispense detergent into them when passing through them, but can directly dispense detergent through the second dispensing part 310. The fourth storage compartment 320 can be dispensed with detergent when passing through the first dispensing part 120.

[0154] After the drive unit 500 rotates through the corresponding angle, the required number of fully loaded sub-storage compartments 320 are dispensed through the second dispensing unit 310, ensuring accurate dispensing of the washing dosage.

[0155] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by the present invention.
