Description

Technical Field

[0001] The invention belongs to the technical field of household appliances, and in particular, relates to a washing control method and a washing machine. Background Art

[0002] During the washing process of the washing machine, the water pressure in the environment used by the user is different, and the water pressure will affect the length of the water inlet time. If the water inlet time is preset only according to the standard water pressure in the washing program, the water intake at the preset water inlet time will be insufficient. If the water intake is required to reach the preset water level, the water inlet time will need to be extended. The extended water inlet time will inevitably cause the overall washing process to be extended. At this time, if the water inlet time is compensated only by shortening the washing time, the shortened washing time will result in poor washing effect, which will cause inconvenience to the user and affect the user's washing experience.

[0003] In view of this, the present invention is proposed. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a washing control method. When the actual water pressure is different from the standard water pressure, different washing adjustment instructions can be executed according to the relationship between the washing water inlet time and the water inlet time threshold, and then different washing parameters can be adjusted to ensure that the washing program can be completed within the original specified time and does not affect the washing effect; the present invention also discloses a washing machine using the above-mentioned washing control method.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0006] One object of the present invention is to provide a washing control method, comprising:

[0007] When the washing machine starts and the water is filled, the washing water filling time is detected;

[0008] Different washing adjustment instructions are executed according to the relationship between the washing water inlet time and the water inlet time threshold.

[0009] Furthermore, the washing adjustment instruction includes adjusting the amount of detergent added and / or the washing water flow and / or the heating temperature.

[0010] Furthermore, when the washing water inlet time is greater than the water inlet time threshold, while ensuring that the detergent concentration remains unchanged, the washing water flow is increased and / or the heating temperature is increased to improve the washing effect while shortening the washing time; when the washing water inlet time is less than or equal to the water inlet time threshold, normal washing program instructions are executed, or the washing water flow and / or water temperature is reduced to make washing more energy-efficient.

[0011] Further, the water inlet time threshold is the longest water inlet time preset in the washing control system of the washing machine.

[0012] Further, when the washing water inlet time is less than or equal to the water inlet time threshold, if the washing water inlet volume reaches the preset water volume at this time, obtain the actual water inlet flow rate, the difference between the actual water inlet time and the standard water inlet time, and adjust the washing water flow and / or the washing heating temperature and / or the rinsing washing parameters in the rinsing program accordingly; if the washing water inlet volume does not reach the preset water volume at this time, the washing machine continues to execute the water inlet instruction until the washing water inlet time is greater than the water inlet time threshold or the washing water inlet volume reaches the preset water volume of the washing water inlet.

[0013] Further, the rinsing washing parameters include one or more of the rinsing water inlet time, the rinsing time, the rinsing rotation speed, and the rinsing temperature.

[0014] Further, adjusting the washing water flow and the washing heating temperature according to the difference between the actual water inlet time and the standard water inlet time includes: determining the washing water flow adjustment coefficient k1 and the heating temperature adjustment coefficient k2 according to the magnitude of the difference Δt between the actual water inlet time and the standard water inlet time. If Δt < 0, 0 < k1 < 1, 0 < k2 < 1; if Δt = 0, k1 = k2 = 1; if Δt > 0, k1 > 1, k2 > 1.

[0015] Further, when the washing water inlet time is greater than the water inlet time threshold, if the washing water inlet volume reaches the minimum water volume at this time, obtain the dosing coefficient, the difference between the actual water inlet time and the standard water inlet time, and adjust the detergent dosing amount and / or the washing water flow and / or the washing heating temperature accordingly; if the washing water inlet volume does not reach the minimum water volume at this time, the washing machine executes an alarm query prompt instruction.

[0016] Further, the dosing coefficient is k3 = V / V1, where V is the washing water inlet volume and V1 is the preset water volume of the washing water inlet. Accordingly, the adjustment formula for the detergent dosing amount is Dt = k3*D0; the adjustment formula for the washing water flow is Rt = k1*R0, and the adjustment formula for the heating temperature is Tt = k2*T0, where D0, R0, and T0 are the current detergent dosing amount, the current washing water flow, and the current heating temperature before adjustment, and Dt, Rt, and Tt are the detergent dosing amount, the washing water flow, and the heating temperature after adjustment.

[0017] Another object of the present invention is to provide a washing machine that applies any one of the above-described washing control methods.

[0018] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0019] 1. The present invention proposes a washing control method. When the actual water pressure is different from the standard water pressure, different washing adjustment instructions can be executed according to the relationship between the washing water inlet time and the water inlet time threshold, and then different washing parameters can be adjusted to ensure that the washing program can be completed within the original specified time and does not affect the washing effect.

[0020] 2. When the actual water pressure is lower than the standard water pressure, the washing water intake time is longer than the standard time, resulting in a reduction in washing time. Accordingly, the amount of detergent added can be adjusted, the washing water flow can be increased, or the water temperature can be increased to ensure the washing effect of the clothes without extending the washing time; when the actual water pressure is equal to the standard water pressure, the clothes can be washed according to the standard washing parameters; when the actual water pressure is higher than the standard water pressure, it proves that the current water pressure is high, the washing water intake time is less than the standard time, and the washing time is increased accordingly. The washing water flow or the water temperature can be adjusted accordingly. The later rinsing water intake time and other rinsing washing parameters can also be adjusted according to the washing water intake flow rate. While ensuring the washing effect, energy waste is reduced to make the washing process more energy-efficient.

[0021] 3. The present invention proposes an injection coefficient of k3=V / V1, wherein V is the washing water intake, and V1 is the preset water volume of the washing water intake. Accordingly, the adjustment formula of the detergent injection amount is Dt=k3*D0; the adjustment formula of the washing water flow is Rt=k1*R0, and the adjustment formula of the heating temperature is Tt=k2*T0, wherein k1 is the washing water flow adjustment coefficient, k2 is the heating temperature adjustment coefficient, D0, R0, and T0 are the current detergent injection amount, current washing water flow, and current heating temperature before adjustment, and Dt, Rt, and Tt are the adjusted detergent injection amount, adjusted washing water flow, and adjusted heating temperature; according to the proposed adjustment formula, the detergent injection amount, washing water flow, and heating temperature can be accurately adjusted, thereby making the clothing washing process more efficient and reasonable.

[0022] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but are intended to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0028] 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.

[0029] 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.

[0030] 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.

[0031] During the washing operation of the washing machine, due to different user environments, the unstable water pressure will often affect the washing water intake time. If the washing water intake time is prolonged, the washing and rinsing time of the clothes will be shortened, affecting the washing effect and reducing the washing quality; if the washing water intake time is shortened, the washing time will increase accordingly, resulting in increased energy consumption in the washing process.

[0032] Combination Figure 1-2 As shown, the present invention provides a washing control method, comprising:

[0033] When the washing machine starts and the water is filled, the washing water filling time is detected;

[0034] Different washing adjustment instructions are executed according to the relationship between the washing water inlet time and the water inlet time threshold.

[0035] It is easy to understand that the method of detecting and obtaining the washing water inlet time in the prior art is: installing a water level sensor in the inner drum of the washing machine, and determining the water inlet time by detecting the water level change. When the washing machine starts to fill with water, the water level sensor will sense and detect the rise of the water level, and the water level sensor will transmit the signal output to the control system. When the water level reaches the washing water level set in the control system, the control system will control the water inlet valve to close and stop the water from flowing in.

[0036] The water inlet time threshold is the preset maximum water inlet time in different washing modes pre-stored in the washing machine system. When the user selects the required washing mode, it is equivalent to selecting the corresponding washing parameters, including the water inlet time threshold in the washing mode.

[0037] Furthermore, the washing adjustment instruction includes adjusting the detergent dosage and / or the washing water flow and / or the heating temperature.

[0038] Specifically, by adjusting the amount of detergent added, the decontamination ability of the washing water solution can be adjusted to ensure the washing effect of the clothes; by adjusting the washing motor start-stop ratio parameters, the intensity of the washing water flow can be adjusted, thereby affecting the washing time and washing effect of the clothes; by adjusting the heating temperature, the dissolution and removal of stains on the clothes can be affected, thereby affecting the washing time and washing effect of the clothes.

[0039] The washing machine adjusts and executes different washing adjustment instructions according to the relationship between the washing water inlet time and the water inlet time threshold: when the washing water inlet time is greater than the water inlet time threshold, while ensuring that the detergent concentration remains unchanged (the same as the detergent concentration when the standard water volume is used), increasing the washing water flow and / or raising the heating temperature can improve the washing effect while shortening the washing time, and can also ensure the rinsing effect of the clothes in the later stage; when the washing water inlet time is less than or equal to the water inlet time threshold, execute normal washing program instructions, or reduce the washing water flow and / or water temperature to make washing more energy-efficient.

[0040] When the inlet water pressure is low, the washing water inlet time is extended, which in turn causes the washing water inlet time to be greater than the water inlet time threshold. Ensuring the detergent concentration remains unchanged can ensure that the dirt-dissolving capacity of the washing water remains unchanged, thereby ensuring the washing effect of the clothes. Increasing the washing water flow is generally achieved by increasing the start-stop ratio of the washing motor. Increasing the start-stop ratio of the washing motor can increase the proportion of the motor rotation time, enhance the water flow rotation frequency, and thereby increase the washing intensity of the clothes and shorten the washing time. Increasing the washing water temperature can enhance the dirt removal ability of clothing washing. The temperature increase can effectively destroy grease, protein and other stains on clothing fibers, and make the detergent easier to dissolve and better penetrate into the clothing fibers, thereby more thoroughly removing various stains adhering to the clothes.

[0041] Optionally, the user can improve the washing effect, shorten the washing time, and thus improve the washing efficiency by increasing the detergent concentration, strengthening the washing water flow, and increasing the heating temperature.

[0042] When the inlet water pressure is equal to the standard water pressure, the washing inlet time is equal to the standard inlet time. In this case, the normal washing program instructions can be executed to complete the normal washing process.

[0043] When the inlet water pressure is high, the washing water inlet time is short, which results in the washing water inlet time being less than the water inlet time threshold. At this time, while the original entire washing program time remains unchanged, the washing and / or rinsing time of the clothes is extended. Therefore, the washing water flow and / or water temperature can be reduced. Lowering the washing water flow or water temperature can reduce damage to the clothes, such as shrinkage, deformation, fading, etc., especially for temperature-sensitive clothing fabrics, such as silk, wool, etc., lowering the water temperature can protect the clothing fabrics to a certain extent and reduce deformation or wear of the clothes; reducing the washing water flow is achieved by reducing the start-stop ratio of the washing motor. Reducing the start-stop ratio of the washing motor and the water temperature will reduce the energy consumption of the washing machine, thereby making the washing process more energy-efficient while ensuring the original washing effect.

[0044] As a possible embodiment of the present application, when the washing water inlet time is less than or equal to the water inlet time threshold, if the washing water inlet amount at this time reaches the preset water amount, the actual water inlet flow rate, the difference between the actual water inlet time and the standard water inlet time are obtained, and the washing water flow and / or the washing heating temperature and / or the rinsing washing parameters in the rinsing program are adjusted accordingly; if the washing water inlet amount at this time does not reach the preset water amount, the washing machine continues to execute the water inlet instruction until the washing water inlet time is greater than the water inlet time threshold or the washing water inlet amount reaches the preset water amount of the washing water inlet.

[0045] Specifically, when the washing water inlet time is less than or equal to the water inlet time threshold, if the washing water inlet volume at this time reaches the preset water volume, the actual water inlet flow rate, the difference between the actual water inlet time and the standard water inlet time are obtained, and the washing water flow and washing heating temperature are adjusted according to the difference between the actual water inlet time and the standard water inlet time, and the rinsing and washing parameters in the rinsing program are adjusted according to the actual water inlet flow rate; if the washing water inlet volume at this time does not reach the preset water volume, the washing machine continues to execute the water inlet instruction until the washing water inlet time is greater than the water inlet time threshold or the washing water inlet volume reaches the preset water volume of the washing water inlet.

[0046] The adjustment of the washing water flow and the washing heating temperature according to the difference between the actual water inlet time and the standard water inlet time includes:

[0047] Calculate the difference Δt between the actual water inlet time t and the standard water inlet time T1: Δt = t-T1;

[0048] Determine the washing water flow adjustment coefficient k1 and the heating temperature adjustment coefficient k2 according to the magnitude of the difference Δt between the actual water inlet time t and the standard water inlet time T1;

[0049] If Δt < 0, 0 < k1 < 1, 0 < k2 < 1; in this case, it indicates that the current water pressure is relatively high, the washing water inlet time is less than the standard time, the washing time is correspondingly increased. Correspondingly, the washing water flow or water temperature can be reduced to make the washing process more energy-efficient;

[0050] If Δt = 0, k1 = k2 = 1; in this case, it indicates that the current water pressure is the standard water pressure, and the washing can be carried out according to the standard washing parameters preset in the washing machine;

[0051] If Δt > 0, k1 > 1, k2 > 1; in this case, it indicates that the current water pressure is relatively low, the washing water inlet time is more than the standard time, the washing time is correspondingly reduced, and the washing water flow can be increased or the water temperature can be raised accordingly to improve the washing effect.

[0052] Adjust the washing water flow and the heating temperature respectively according to the obtained values of the washing water flow adjustment coefficient k1 and the heating temperature adjustment coefficient k2. The adjustment formula for the washing water flow is Rt = k1 * R0, and the adjustment formula for the heating temperature is Tt = k2 * T0, where R0 and T0 are the current washing water flow and the current heating temperature before adjustment, and Rt and Tt are the adjusted washing water flow and the adjusted heating temperature.

[0053] Further, obtain the actual washing water inlet flow rate including q = V / t, and adjust the subsequent rinsing and washing parameters according to the actual washing water inlet flow rate, where the rinsing and washing parameters include one or more of the rinsing water inlet time, the rinsing time, the rinsing rotation speed, and the rinsing temperature.

[0054] Adjusting the rinsing and washing parameters in the rinsing program according to the actual water inlet flow rate includes:

[0055] If the actual washing water inlet flow rate is higher than the standard water inlet flow rate, it may cause the rinsing water inlet time to be shortened and the rinsing time to be prolonged. Further, the rinsing rotation speed can be adjusted downwards and the rinsing temperature can be reduced accordingly to make the washing process milder and more energy-efficient; if the actual washing water inlet flow rate is equal to the standard water inlet flow rate, the rinsing program can be carried out according to the rinsing and washing parameters preset in the washing machine; if the actual washing water inlet flow rate is lower than the standard water inlet flow rate, it may cause the rinsing water inlet time to be prolonged and the rinsing time to be shortened, and the rinsing rotation speed and the rinsing temperature can be increased accordingly to improve the rinsing quality and effect of the clothes.

[0056] As another possible embodiment of the present invention: when the washing water inlet time is greater than the water inlet time threshold, if the washing water inlet volume at this time reaches the minimum water volume, the injection coefficient, the difference between the actual water inlet time and the standard water inlet time are obtained, and the detergent injection amount and / or the washing water flow and / or the washing heating temperature are adjusted accordingly; if the washing water inlet volume at this time does not reach the minimum water volume, the washing machine executes a warning prompt instruction.

[0057] Furthermore, when the washing water inlet time is greater than the water inlet time threshold (the water inlet pressure is low), if the washing water inlet volume at this time reaches the minimum water volume, the injection coefficient, the difference between the actual water inlet time and the standard water inlet time are obtained, and the detergent injection amount is adjusted according to the injection coefficient, and the washing water flow and washing heating temperature are adjusted according to the difference between the actual water inlet time and the standard water inlet time; if the washing water inlet volume at this time does not reach the minimum water volume, the washing machine executes an alarm prompt instruction.

[0058] The method for obtaining the release coefficient and the difference between the actual water inflow time and the standard water inflow time in the above technical solution includes:

[0059] The injection coefficient is k3 = V / V1, where V is the washing water intake and V1 is the preset water intake for washing;

[0060] The difference between the actual water inlet time and the standard water inlet time is Δt, Δt=t-T1, where t is the actual water inlet time and T1 is the standard water inlet time.

[0061] Furthermore, adjusting the detergent dosage according to the dosage coefficient k3 includes: the dosage coefficient is k3=V / V1, wherein V is the washing water volume, and V1 is the preset washing water volume. Accordingly, the adjustment formula of the detergent dosage is Dt=k3*D0.

[0062] Specifically, when the washing water inlet time is greater than the water inlet time threshold and the washing water inlet volume reaches the minimum water volume, the injection coefficient is k3=V / V1 and k3<1. At this time, according to the adjustment formula of the detergent injection amount Dt=k3*D0, the detergent injection amount is reduced. In addition, since the detergent concentration remains unchanged during the detergent injection process (the same as the detergent concentration at the standard water inlet volume), the washing water inlet volume decreases due to the low water pressure. It can also be deduced that the detergent injection amount under this condition is reduced. Since the detergent concentration remains unchanged, the dirt dissolving capacity of the washing water can be guaranteed to remain unchanged, ensuring the washing effect of the clothes. At the same time, the reduction in the amount of detergent injection can also improve the rinsing effect of the clothes.

[0063] Adjusting the washing water flow and washing heating temperature according to the difference between the actual water inlet time and the standard water inlet time includes: the adjustment formula of the washing water flow is Rt=k1*R0, and the adjustment formula of the heating temperature is Tt=k2*T0, wherein D0, R0, and T0 are the current detergent amount, current washing water flow, and current heating temperature before adjustment, and Dt, Rt, and Tt are the adjusted detergent amount, adjusted washing water flow, and adjusted heating temperature.

[0064] When the washing water inlet time is greater than the water inlet time threshold and the washing water inlet volume reaches the minimum water volume, the difference between the actual water inlet time and the standard water inlet time is Δt, Δt=t-T1>0. When Δt>0, the washing water flow adjustment coefficient k1>1, the heating temperature adjustment coefficient k2>1, and the washing water flow or water temperature can be increased accordingly to improve the washing effect.

[0065] Therefore, as a possible embodiment of the present application, when the washing water inlet time is greater than the water inlet time threshold and the washing water inlet volume reaches the minimum water volume, the washing program is adjusted to reduce the amount of detergent (the detergent concentration remains unchanged, and is the same as the detergent concentration at the standard water volume), enhance the washing water flow or increase the water temperature, thereby improving the washing effect of the clothes, shortening the washing time and improving the rinsing quality.

[0066] During the execution of the washing machine, based on the relevant data of the current detergent dosage, current washing water flow, and current heating temperature during the operation of the washing machine, the control system calculates the adjusted detergent dosage, washing water flow, and heating temperature values ​​according to the preset dosage coefficient calculation formula, detergent dosage adjustment formula, washing water flow adjustment formula, and heating temperature adjustment formula, and then transmits the adjusted relevant washing data to the washing machine execution structure, thereby improving the washing effect of the washing machine and making the washing process gentler and more energy-efficient.

[0067] As an embodiment of the present application, when the washing water inlet time is greater than the water inlet time threshold, and the washing water inlet volume at this time does not reach the minimum water volume, the washing machine executes a warning prompt instruction. Further, the washing machine executes the warning prompt instruction including the washing machine issuing a low water pressure prompt and confirming whether the user extends the washing time. The washing machine issues a low water pressure prompt by directly controlling the alarm device through the control system of the washing machine device to issue a corresponding sound prompt, or by connecting the control system to the user's smart device signal and sending a corresponding prompt message to the user's smart device.

[0068] After all the above washing adjustment instruction programs are completed, the washing machine starts washing, and executes all washing parameters adjusted according to the washing adjustment instructions during the washing process.

[0069] The present invention application also discloses a washing machine, which applies any of the above-mentioned washing control methods.

[0070] After adopting the above-mentioned embodiments, the present invention has the following beneficial technical effects compared with the prior art:

When the actual water pressure is different from the standard water pressure, different washing adjustment instructions can be executed according to the relationship between the washing water inlet time and the water inlet time threshold, and then different washing parameters can be adjusted to ensure that the washing program can be completed within the original specified time and does not affect the washing effect.

[0072] When the actual water pressure is lower than the standard water pressure, the washing water intake time is longer than the standard time, resulting in a reduction in washing time. Accordingly, the amount of detergent added can be adjusted, the washing water flow can be increased, or the water temperature can be increased to ensure the washing effect of the clothes without extending the washing time; when the actual water pressure is equal to the standard water pressure, the clothes can be washed according to the standard washing parameters; when the actual water pressure is higher than the standard water pressure, it proves that the current water pressure is high, the washing water intake time is less than the standard time, and the washing time is increased accordingly. The washing water flow or the water temperature can be adjusted accordingly. The later rinsing water intake time and other rinsing washing parameters can also be adjusted according to the washing water intake flow rate. While ensuring the washing effect, energy waste is reduced to make the washing process more efficient and energy-saving.

[0073] The present invention proposes an injection coefficient of k3=V / V1, wherein V is the washing water intake, V1 is the preset water volume of the washing water intake, and according to the obtained injection coefficient k3, the adjustment formula of the detergent injection amount is Dt=k3*D0; the adjustment formula of the washing water flow is Rt=k1*R0, and the adjustment formula of the heating temperature is Tt=k2*T0, wherein k1 is the washing water flow adjustment coefficient, k2 is the heating temperature adjustment coefficient, D0, R0, T0 are the current detergent injection amount, the current washing water flow, and the current heating temperature before adjustment, and Dt, Rt, Tt are the adjusted detergent injection amount, the adjusted washing water flow, and the adjusted heating temperature; according to the proposed adjustment formula, the detergent injection amount, the washing water flow, and the heating temperature can be accurately adjusted, thereby making the clothing washing process more efficient and reasonable.

[0074] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention.
