[0039] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not used to limit the scope of protection of the present invention. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0040] It should be noted that in the description of the present invention, the terms "upper", "lower", "inner", "outer", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the relevant devices or elements must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, ordinal numbers "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0041] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation" and "connection" 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 those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] When the user selects the drum self-cleaning program of existing washing equipment, the drum self-cleaning time is fixed, and the program cannot judge the degree of dirtiness in the drum by itself. Regardless of the difference in the cleaning conditions in the drum, the same process will be adopted. In this case, the drum cleaning time is too long, resulting in energy waste, and the drum cleaning time is insufficient, resulting in incomplete cleaning, which affects the subsequent use effect.

[0043] In order to solve the above technical problems, the present invention provides a washing device, which includes an inner drum, a drying module and a weighing sensor. A heating pipe is installed in the washing device for heating washing water, the drying module is used to dry clothes, and the weighing sensor is used to measure the load weight of washing. It should be noted that the drying module is a prior art known to those skilled in the art, so it will not be described in detail here.

[0044] Also, see Figure 1 The present invention also provides a drum cleaning control method for a washing device, the drum cleaning control method comprising:

[0045] S1, entering a drum cleaning mode upon receiving a drum cleaning start instruction;

[0046] S2, obtaining a drum cleaning coefficient A according to the washing parameters;

[0047] S3, selectively controlling the washing device to execute cleaning modes of different gears according to the size of the drum cleaning coefficient A;

[0048] Among them, the washing parameters include total washing time, total heating time, total drying time, total number of rinses, total washing load weight and total water hardness of the area.

[0049] In the above embodiment, the total washing time refers to the time value obtained by accumulating the washing time of each time; the total heating time refers to the time value obtained by accumulating the heating time of each time; the total drying time refers to the time value obtained by accumulating the drying time of each time; the total number of rinsing times refers to the total number of rinsing times accumulated in each operation; the total washing load weight refers to the cumulative total weight of the items washed each time; the total regional water hardness refers to the hardness value of the washing water each time, and these parameters are all stored in the washing device.

[0050] In the present application, the hardness value of the washing water can be obtained by detecting a water hardness detector installed in the washing equipment, or by locating the area through a mobile phone APP and sending the water hardness value corresponding to the area to the washing equipment for acquisition.

[0051] In one embodiment, the step of "obtaining the drum cleaning coefficient A according to the washing parameters" further comprises:

[0052] Calculate the drum cleanliness factor according to the following formula;

[0053] A=aW+bP+cT+dS+eK+fH

[0054] Among them, a, b, c, d, e, and f are all coefficients; W is the total washing time; P is the total heating time; T is the total drying time; S is the total number of rinsing times; K is the total washing load weight; and H is the total water hardness of the area.

[0055] In the above formula, the value of coefficient a is 0.9 to 1.1, the value of coefficient b is 0.4 to 0.6, the value of coefficient c is 1.4 to 1.6, the value of coefficient d is -0.4 to -0.6, the value of coefficient e is 0.4 to 0.6, the value of coefficient f in the northern region is 1.1, and the value of coefficient f in the southern region is 0.95. For example, the value of coefficient a is 1, the value of coefficient b is 1, the value of coefficient c is 1.5, the value of coefficient d is -0.5, and the value of coefficient e is 0.5.

[0056] In the above embodiment, since the washing parameters such as total washing time, total heating time, total drying time, total rinsing times, total washing load weight and total water hardness of the area all have an impact on the degree of dirtiness of the drum, these parameters are used to calculate the drum cleaning coefficient, which is beneficial to improve the accuracy of judgment.

[0057] In one embodiment, the cleaning modes of different gears include at least a first gear cleaning mode, a second gear cleaning mode and a third gear cleaning mode. Figure 2 The step S3 of "selectively controlling the washing device to execute cleaning modes of different gears according to the size of the drum cleaning coefficient A" specifically includes:

[0058] S31, if the drum cleaning coefficient A is greater than zero and less than or equal to a first preset value, controlling the washing device to perform cleaning in a first gear cleaning mode;

[0059] S32, if the drum cleaning coefficient A is greater than the first preset value and less than or equal to the second preset value, controlling the washing device to perform cleaning in the second gear cleaning mode;

[0060] S33, if the drum cleaning coefficient A is greater than the second preset value, the washing device is controlled to perform cleaning in the third gear cleaning mode.

[0061] It should be noted that the number of gears of the cleaning mode of different gears is not limited to three gears, and can also be four gears or five gears, etc., which can be flexibly set according to design and use requirements. Regarding the specific values ​​of the first preset value, the second preset value and the third preset value, this application does not make specific restrictions, and they are flexibly set according to actual use. For example, the first preset value is 10 and the second preset value is 50.

[0062] In the above embodiment, different gears of cleaning modes are executed according to the size of the drum cleaning coefficient A, realizing the function of automatically adjusting the cleaning intensity, making cleaning more intelligent, and being beneficial to saving energy and improving the cleaning effect.

[0063] In one embodiment, the execution time of the first gear cleaning mode, the second gear cleaning mode and the third gear cleaning mode of the washing machine increases sequentially.

[0064] In the above embodiment, since the higher the gear, the greater the cleaning force, the longer the execution time, the more helpful it is to clean the dirt that is not easy to clean. This application does not make specific restrictions on the execution time of each gear. Without deviating from the basic principles of the present invention, it can be flexibly set according to the usage and cleaning ability. For example, the execution time of the first gear cleaning mode is 8 minutes; the execution time of the second gear cleaning mode is 90 minutes; and the execution time of the third gear cleaning mode is 120 minutes.

[0065] In one embodiment, the amount of water injected in the first-gear cleaning mode, the second-gear cleaning mode, and the third-gear cleaning mode increases sequentially.

[0066] Specifically, the water injection amount in the water injection stage involved in the first-gear cleaning mode is the same, and the water injection amount in the water injection stage involved in the second-gear cleaning mode is the same; the water injection amount in the water injection stage involved in the third-gear cleaning mode is the same, and the water injection amount for each time in the first-gear cleaning mode is smaller than the water injection amount for each time in the second-gear cleaning mode, and the water injection amount for each time in the second-gear cleaning mode is smaller than the water injection amount for each time in the third-gear cleaning mode.

[0067] In the above embodiment, since the higher the gear position, the greater the cleaning force, the amount of water injected into the inner drum of the washing device increases with the increase of the gear position, which helps to increase the agitation force, thereby helping to clean the dirt that is not easy to clean. This application does not make specific restrictions on the amount of water injected at each gear position. It can be flexibly set according to the usage and cleaning ability without deviating from the basic principles of the present invention. Exemplarily, the amount of water injected each time in the first gear cleaning mode is more than 3 cm from the edge of the drum; the amount of water injected each time in the second gear cleaning mode is more than 6 cm from the edge of the drum; the amount of water injected each time in the third gear cleaning mode is more than 9 cm from the edge of the drum.

[0068] In one embodiment, both the second gear cleaning mode and the third gear cleaning mode heat the injected water, and the temperature of the water heated in the second gear cleaning mode is lower than the temperature of the water heated in the third gear cleaning mode. If the number of gears is greater than three, except for the first gear, the rest need to be heated, and the heating temperature gradually increases.

[0069] In one embodiment, the first gear cleaning mode includes a first main wash stage, a first dehydration stage, a first rinsing stage and a second dehydration stage, wherein the first main wash stage is to control the washing device to rotate alternately at a first preset speed and a second preset speed after water is injected into the washing device to generate agitation. The second preset speed is greater than the first preset speed. The rotation mode of the first rinsing stage is the same as the rotation mode of the first main wash stage.

[0070] Specifically, the alternating interval between the first preset speed and the second preset speed is 1 minute, the inner drum rotates forward for 30 seconds at the first preset speed, reverses for 30 seconds, and then rotates forward for 30 seconds at the second preset speed, reverses for 30 seconds. It should be noted that the alternating interval described above is only an example, and this application does not make a specific limitation, and it can be flexibly set according to actual conditions.

[0071] At the end of the first main wash stage, the water is drained and the first dehydration stage is entered. In the first dehydration stage, the inner drum of the washing device is controlled to rotate at a dehydration speed. After the first dehydration stage, water is injected into the inner drum to enter the first rinsing stage. After the first rinsing stage, the second dehydration stage is entered. In the second dehydration stage, the inner drum of the washing device is controlled to rotate at a dehydration speed. The first dehydration stage and the second dehydration stage are both for shaking off the water on the inner drum to achieve the purpose of drying and avoid the breeding of bacteria. The maintenance time of the first dehydration stage and the second dehydration stage are both 10s to 20s. The maintenance time of the first rinsing stage is 2min to 3min. The maintenance time of the first main wash stage is the remaining time after deducting the first rinsing stage, the first dehydration stage and the second dehydration stage from the execution time of the first gear cleaning mode.

[0072] In addition, it should be noted that the specific values ​​of the first preset speed, the second preset speed and the spin speed are not specifically limited in this application, and can be flexibly set according to actual usage without deviating from the basic principles of the present invention. For example, the first preset speed is 50 rpm, the second preset speed is 150 rpm, and the spin speed is 400 rpm.

[0073] In the above embodiment, in the first main wash stage, the first preset speed and the second preset speed are rotated alternately. Due to the different agitation forces and flushing areas generated by different speeds, the strong agitation force is helpful to clean stubborn stains, and the water with small agitation force is used for flushing, which saves energy while ensuring that the stubborn stains can be cleaned.

[0074] In one embodiment, the second gear cleaning mode includes a second main wash stage, a third dehydration stage, a second rinsing stage, and a fourth dehydration stage, wherein the second main wash stage includes a first heating main wash stage and a first heat preservation main wash stage, wherein the first heating main wash stage is to heat and heat up the washing device after injecting water into the washing device, and control the washing device to rotate at a third preset speed during the heating process; the first heat preservation main wash stage is to control the washing device to rotate alternately at a fourth preset speed and a fifth preset speed in a heat preservation state; wherein the third preset speed, the fourth preset speed, and the fifth preset speed increase in sequence. The rotation mode of the second rinsing stage is the same as the rotation mode of the second main wash stage.

[0075] Specifically, a heating pipe is installed in the washing device. When the injected water is heated to the first preset temperature in the first heating main wash stage, the heating is stopped and the water enters the insulation state. In the insulation state, the water temperature is within the range of ±5°C of the first preset temperature, and the heating pipe is not heated. If the water temperature is lower than this range, the heating starts, and if it is higher than this range, the heating stops. The specific value of the first preset temperature is not specifically limited in this application, and it is flexibly set according to actual usage. For example, the first preset temperature is 75°C.

[0076] In addition, the alternating interval between the fourth preset speed and the fifth preset speed is 1 minute. For example, the inner drum rotates forward for 30 seconds at the fourth preset speed and reverses for 30 seconds, and then rotates forward for 30 seconds at the fifth preset speed and reverses for 30 seconds. It should be noted that the alternating interval described above is only an example, and is not specifically limited in this application and can be flexibly set according to actual conditions.

[0077] In the above embodiment, the washing water in the drum is heated to help clean stubborn stains, and the second main wash stage is performed after water is injected into the drum, and the water is drained after the third dehydration stage is performed after the execution is completed, and the second rinsing stage is performed after the execution is completed. The third dehydration stage and the fourth dehydration stage are both spin-dried at a dehydration speed.

[0078] The duration of the third and fourth dehydration stages is 10s to 20s. The duration of the second rinse stage is 2min to 3min. The duration of the second main wash stage is the remaining duration after deducting the second rinse stage, the third dehydration stage and the fourth dehydration stage from the execution time of the second gear cleaning mode.

[0079] In addition, it should be noted that the specific values ​​of the third preset speed, the fourth preset speed, the fifth preset speed and the dehydration speed are not specifically limited in this application, and are flexibly set according to actual use without deviating from the basic principles of the present invention. For example, the third preset speed is 50 rpm, the fourth preset speed is 70 rpm, the fifth preset speed is 150 rpm, and the dehydration speed is 400 rpm.

[0080] In the above embodiment, the third preset speed in the first heating main wash stage is smaller than the speed in the first insulation main wash stage. The lower speed in the heating stage is to avoid the problem of high heating of the heating tube due to low water level caused by high speed carrying away water flow, thereby improving safety.

[0081] In one embodiment, the third gear cleaning mode includes a third main wash stage, a fifth spin-drying stage, a third rinsing stage and a sixth spin-drying stage, wherein the third main wash stage includes a second heating main wash stage and a second heat preservation main wash stage, the second heating main wash stage is to heat and raise the temperature after injecting water into the washing device, and control the washing device to rotate at a sixth preset speed during the heating process; the second heat preservation main wash stage is to control the washing device to rotate alternately at a seventh preset speed and an eighth preset speed in a heat preservation state;

[0082] The sixth preset speed, the seventh preset speed, and the eighth preset speed increase in sequence. The rotation mode of the third rinsing stage is the same as the rotation mode of the third main washing stage.

[0083] Specifically, in the second heating main wash stage, the injected water is heated to the second preset temperature, and then the heating is stopped and the water enters the insulation state. In the insulation state, the water temperature is within the range of ±5°C of the second preset temperature, and the heating tube is not heated. If the water temperature is lower than this range, the heating starts, and if it is higher than this range, the heating stops. The specific value of the second preset temperature is not specifically limited in this application, and it is flexibly set according to actual use. For example, the second preset temperature is 90°C.

[0084] In addition, the alternating interval between the seventh preset speed and the eighth preset speed is 1 minute. For example, the inner drum rotates forward for 30 seconds at the seventh preset speed and reverses for 30 seconds, and then rotates forward for 30 seconds at the eighth preset speed and reverses for 30 seconds. It should be noted that the alternating interval described above is only an example, and is not specifically limited in this application and can be flexibly set according to actual conditions.

[0085] In the above embodiment, the washing water in the drum is heated to help clean stubborn stains, and the third main wash stage is performed after water is injected into the drum, and the fifth dehydration stage is performed after the water is drained, and the third rinsing stage is performed after the water is injected into the drum, and the sixth dehydration stage is performed after the water is injected. The fifth dehydration stage and the sixth dehydration stage are both performed at a dehydration speed.

[0086] The duration of the fifth and sixth dehydration stages is 10s to 20s. The duration of the third rinsing stage is 2min to 3min. The duration of the third main wash stage is the remaining duration after deducting the third rinsing stage, the fifth dehydration stage and the sixth dehydration stage from the execution time of the third gear cleaning mode.

[0087] In addition, it should be noted that the specific values ​​of the sixth preset speed, the seventh preset speed, the eighth preset speed and the dehydration speed are not specifically limited in this application, and are flexibly set according to actual use without deviating from the basic principles of the present invention. For example, the sixth preset speed is 50 rpm, the seventh preset speed is 70 rpm, the eighth preset speed is 150 rpm, and the dehydration speed is 400 rpm.

[0088] In the above embodiment, the sixth preset speed in the second heating main wash stage is smaller than the speed in the second insulation main wash stage. The lower speed in the heating stage is to avoid the problem of high heating of the heating tube due to low water level caused by high speed carrying away water flow, thereby improving safety.

[0089] In addition, in the present application, the number of rinsing stages involved in the first gear cleaning mode, the second gear cleaning mode and the third gear cleaning mode is not specifically limited. In the above embodiment, the number of rinsing stages is one, and it can also be set to two or three times, which can be flexibly set according to actual usage. A dehydration stage is performed at the end of each rinsing stage.

[0090] In one embodiment, the drum cleaning control method further comprises:

[0091] After the step of "selectively controlling the washing device to perform cleaning modes of different gears according to the drum cleaning coefficient A" is completed, the drum cleaning coefficient is reset to zero. This is convenient for recalculation during the next cleaning, and the measurement is more accurate.

[0092] In a specific embodiment of the drum cleaning control method of the above washing equipment, the drum cleaning control method further includes:

[0093] Obtain the cumulative running time of the washing equipment;

[0094] Compare the accumulated running time with the preset total running time;

[0095] If the accumulated running time is greater than or equal to the preset total running time, a reminder instruction for drum self-cleaning is sent;

[0096] When the drum self-cleaning mode ends, the accumulated running time is reset to zero.

[0097] In the above embodiment, the operating time refers to the duration of the entire process from starting to stopping the washing device. The operating time of each time of the washing device is accumulated to obtain the cumulative operating time. Whether the drum needs to be cleaned is determined based on the cumulative operating time, thereby realizing an automatic judgment function, which helps to remind users to clean the washing device regularly to avoid the growth of more bacteria and the generation of odors that affect the washing effect.

[0098] It should be noted that, at the end of the drum cleaning mode, the user can issue a command to execute drum cleaning again according to the situation to control the washing device to execute the drum cleaning mode.

[0099] In addition, the present invention also provides a washing device, including a controller, wherein the controller is configured to be able to execute the drum cleaning control method of the washing device as described in any one of the above technical solutions.
