[0002] Washing machines are designed to wash clothes. With the development of technology and the improvement of people's living standards, washing machines have become one of the indispensable appliances in modern families. The popularity of washing machines has made laundry more convenient and faster, and people no longer need to spend a lot of time and energy on washing clothes.

[0003] As technology continues to advance, modern washing machines have even more features and functions.

[0004] However, during the washing process, the washing machine sometimes needs to soak the laundry, and the drum is in a stationary state. In this case, heating the washing machine may easily burn the laundry. That is, when a traditional washing machine heats the washing water, it is unable to adjust the heating mode according to the change in the rotation speed of the drum of the washing machine.

[0005] Accordingly, the art requires a new control method, control device and washing machine for washing equipment to solve the above problems. Summary of the invention

[0018] Determine whether the duration reaches the set heating duration;

[0019] If yes, turn off the heating; otherwise, determine whether the rotation speed exceeds a second set rotation speed, wherein the second set rotation speed is less than the first set rotation speed;

[0020] If yes, continue heating, otherwise pause heating.

[0021] In a specific implementation of the control method of the washing device, the drum is heated by electromagnetic heating.

[0022] In a specific implementation of the control method of the washing device, before the step of "starting the washing program", the control method further includes:

[0023] Start the washing equipment;

[0024] Weigh the laundry;

[0025] According to the weight of the laundry, washing water matching the weight of the laundry is injected into the washing device.

[0026] In a specific implementation of the control method of the above-mentioned washing device, the step of "obtaining the rotational speed of the drum of the washing device" is specifically: obtaining the rotational speed of the drum of the washing device by measuring the rotational speed of the motor of the washing device.

[0027] The present invention also provides a control method for a washing device. The control method comprises the following steps:

[0028] Start the washing equipment;

[0029] Weigh the laundry;

[0030] According to the weight of the laundry, injecting washing water matching the weight of the laundry into the washing device;

[0031] The washing program starts running;

At the same time, some clothes are not suitable for high temperatures, such as silk and wool. The drum of the washing device does not heat when it is stationary, but only heats when the drum is rotating, which can reduce the damage of these materials to clothes by hot water, thereby better protecting the quality and service life of the clothes.

In addition, ordinal numbers such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0060] 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.

[0061] like Figure 1 As shown, the present invention proposes a control method for a washing device. The control method comprises the following steps:

[0062] Step S100: the washing program starts running;

[0063] Step S110: obtaining the rotation speed of the drum of the washing device;

[0064] Step S120: determining whether the rotation speed exceeds a first set rotation speed;

[0065] Step S130: selectively starting the heating roller according to the judgment result;

[0066] Step S140: When the drum is heated, start timing;

[0067] Step S150: obtaining the rotation speed of the drum and the timing duration;

[0068] Step S160: determining whether the rotation speed exceeds the second set rotation speed and whether the duration reaches the heating set duration, wherein the second set rotation speed is less than the first set rotation speed;

[0069] Step S170: According to the judgment result, choose to continue heating, pause heating, or turn off heating.

[0070] In this embodiment, when the drum of the washing device is in a stationary state, the washing device does not start the heating drum. When the drum of the washing device rotates to a first set speed, the washing device starts the heating drum. This setting can avoid scalding or damaging the laundry due to excessive temperature rise of the washing water when the drum is stationary.

[0071] In addition, by heating only when the drum is rotating during the washing process, energy consumption during the entire washing cycle is avoided, thereby achieving energy saving. Compared with heating when the drum is stationary, heating when the drum is rotating can make the hot water come into contact with the laundry more fully, which can better play the role of washing and decontamination, thereby improving the washing effect. At the same time, some clothes are not suitable for high temperatures, such as silk and wool. The drum of the washing device does not heat when it is stationary, but only heats when the drum is rotating, which can reduce the damage of these materials to clothes by hot water, thereby better protecting the quality and service life of the clothes.

[0072] In a possible implementation, the washing device may be a drum washing machine or a pulsator washing machine.

[0073] In a possible implementation manner, the first set rotation speed may be 30 rpm, and the second set rotation speed may be 25 rpm.

[0074] Further, the step S130 of “selectively starting the heating roller according to the judgment result” may specifically include:

[0075] Step S131: When the rotation speed is greater than or equal to the first set rotation speed, the drum is heated.

[0076] In this embodiment, when the rotation speed of the drum of the washing device is greater than or equal to the first set rotation speed, the drum has a relatively high rotation speed. In this case, the drum of the washing device is heated to increase the temperature of the washing water in the drum, which can make the washing water with a higher temperature contact with the laundry more fully and improve the washing effect, and will not cause the temperature of a local position of the drum to rise too quickly and burn the laundry.

[0077] In a possible implementation, when the rotation speed of the drum of the drum washing machine is greater than or equal to 30 rpm, the drum is heated.

[0078] Further, the step S130 of “selectively starting the heating roller according to the judgment result” may further specifically include:

[0079] Step S132: When the rotation speed is less than the first set rotation speed, the drum is not heated.

[0080] In this embodiment, when the rotation speed of the drum of the washing device is less than the first set rotation speed, the drum has a lower rotation speed, and the washing device does not heat the drum, which can avoid excessive temperature rise in a local position of the drum and scalding the laundry, thereby increasing the safety of the washing process and more effectively protecting the laundry.

[0081] It should be noted that when the rotation speed is less than the first set rotation speed, the drum is not heated, which refers to the period from starting the washing device to the time when the rotation speed of the drum of the washing device reaches the first set rotation speed for the first time.

[0082] In a possible implementation, when the rotation speed of the drum of the drum washing machine is less than 30 rpm, the drum is not heated.

[0083] Further, step S170 of “determining whether the speed exceeds the second set speed and whether the duration reaches the heating set duration, wherein the second set speed is less than the first set speed, and selecting to continue heating, pause heating, or turn off heating according to the determination result” may specifically include:

[0084] Step S161: Determine whether the duration reaches the set heating duration;

[0085] Step S171: If yes, turn off the heating; otherwise, determine whether the speed exceeds the second set speed, wherein the second set speed is less than the first set speed;

[0086] Step S172: If yes, continue heating, otherwise pause heating.

[0087] In this embodiment, after the washing device starts heating the drum, it starts to accumulate the heating time. When the accumulated time reaches the set heating time, the function of heating the drum is turned off. In a complete washing cycle, even if the speed of the drum of the washing device exceeds the first set speed, the washing device does not heat the drum. The set heating time can ensure that the hot washing water is fully in contact with the laundry, and can also avoid energy consumption during the entire washing cycle, thereby achieving the technical effect of energy saving.

[0088] When the accumulated time does not reach the set heating time, the relationship between the rotation speed of the drum and the second set rotation speed is continuously determined. When the rotation speed of the drum is greater than the second set rotation speed, it is considered that the drum still has a relatively high rotation speed, and the drum can be continuously heated to increase the temperature of the washing water, thereby improving the washing and decontamination effects of the washing device. When the rotation speed of the drum is less than or equal to the second set rotation speed, it is considered that the drum has a relatively low rotation speed. If the drum is continuously heated, it may cause the local temperature of the drum to rise too fast, thereby causing damage to the laundry. Therefore, the heating of the drum is suspended. When the rotation speed of the drum of the washing device increases again to exceed the second set rotation speed in accordance with the setting of the washing mode, the drum can be continuously heated, and so on.

[0089] Furthermore, the drum is heated by electromagnetic heating.

[0090] Traditional washing machines use electric heating tubes to heat water, which can only fully heat the washing water near them, and as the use time increases, scale will accumulate on the surface of the electric heating tubes. The overall heating time is long and the heating efficiency is low when using electric heating tubes to heat washing water.

[0091] In this embodiment, the electromagnetic heating method is used to heat the drum by using the electromagnetic induction principle to generate heat energy, and an alternating magnetic field is generated by using an alternating current through a coil. When the washing water in the washing device is in the alternating magnetic field, the temperature of the washing water can be increased, thereby providing the user with the required water temperature.

[0092] In a possible implementation, the drum of the washing device may be made of metal.

[0093] In some examples, the drum of the washing machine may be made of stainless steel.

[0094] Further, if Figure 2 As shown, before step S100 of "starting the washing program", the control method may further include:

[0095] Step S70: starting the washing equipment;

[0096] Step S80: weighing the laundry;

[0097] Step S90: According to the weight of the laundry, the washing water matching the weight of the laundry is injected into the washing device.

[0098] In this embodiment, the washing machine can avoid using too much water by matching the amount of washing water according to the weight of the laundry, thereby helping to save water resources, reduce energy consumption, and reduce the impact on the environment. In addition, the correct amount of washing water can prevent the laundry from being damaged due to insufficient or excessive water flow during the washing process. The right amount of washing water is also important for protecting the fibers of the laundry, and can also reduce the risk of wear and deformation of the laundry.

[0099] In a possible implementation, a sensor is provided inside the drum washing machine, and the sensor can detect the weight or capacity of the laundry. The sensor can determine the weight of the laundry by measuring the vibration amplitude inside the washing machine or weighing it.

[0100] Further, the step S110 of “obtaining the rotation speed of the drum of the washing device” may specifically be:

[0101] By measuring the motor speed of the washing device, the rotation speed of the drum of the washing device is obtained.

[0102] In this embodiment, the motor in the washing device drives the drum to rotate, and a sensor is installed to measure the rotation speed of the motor. By monitoring the rotation speed of the motor, the control system of the washing device can obtain the actual rotation speed of the drum.

[0103] In a possible implementation, the sensor may be a Hall sensor, an encoder, or other types of speed sensors.

[0104] like Figure 2 As shown, the present invention also proposes a control method for a washing device. The control method comprises the following steps:

[0105] Step S70: starting the washing equipment;

[0106] Step S80: weighing the laundry;

[0107] Step S90: according to the weight of the laundry to be washed, injecting washing water matching the weight of the laundry to be washed into the washing device;

[0108] Step S100: the washing program starts running;

[0109] Step S110: obtaining the rotation speed of the drum of the washing device;

[0110] Step S120: determining whether the rotation speed exceeds a first set rotation speed;

[0111] Step S131: When the rotation speed is greater than or equal to the first set rotation speed, heating the drum;

[0112] Step S132: when the rotation speed is less than the first set rotation speed, the drum is not heated;

[0113] Step S140: When the drum is heated, start timing;

[0114] Step S150: obtaining the rotation speed of the drum and the timing duration;

[0115] Step S161: Determine whether the duration reaches the set heating duration;

[0116] Step S171: If yes, turn off the heating; otherwise, determine whether the speed exceeds the second set speed, wherein the second set speed is less than the first set speed;

[0117] Step S172: If yes, continue heating, otherwise pause heating.

[0118] In this embodiment, when the drum of the washing device is in a stationary state, the washing device does not start the heating drum. When the drum of the washing device rotates to a first set speed, the washing device starts the heating drum. This setting can avoid the situation where the laundry is scalded or damaged due to excessive local temperature rise of the drum of the washing device when the drum is stationary.

[0119] like Figure 3 As shown, the present invention also proposes a control device 200 for a washing device. The control device 200 comprises:

[0120] A heating module 210, used for electromagnetically heating the drum of a washing device;

[0121] The detection module 220 is used to obtain the rotation speed of the drum of the washing device and the accumulated duration of electromagnetic heating;

[0122] The control module 230 is connected to the heating module 210 and the detection module 220 respectively to implement the control method of the washing device as described in any one of the above embodiments.

[0123] In this embodiment, the control device 200 of the washing machine can control the opening of the heating module 210 according to the change of the rotation speed of the washing machine to avoid scalding or damage to the laundry due to excessive local temperature rise of the drum of the washing machine when the drum is stationary.

[0124] It should be noted that Figure 3 The structural relationship of each module is only used as a schematic description and is not used to represent the actual position relationship.

[0125] The present invention also provides a washing machine. The washing machine comprises:

[0126] roller;

[0127] The washing equipment control device, the drum is connected to the washing equipment control device, and the washing equipment control device is the washing equipment control device in the above embodiment, so as to implement the control method of the washing equipment as any one of the above embodiments.

[0128] In a possible implementation, the washing equipment control device may include a control board, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the program, the control method in the above embodiment may be implemented.

[0129] The washing machine control device may further include a computer-readable storage medium on which a computer program is stored. When the program is executed by the processor, the washing machine control method as described in the aforementioned method embodiment is implemented.

[0130] For the purposes of this specification, a computer readable medium may be any device that can contain, store, communicate, propagate or transport a program for use with or in conjunction with an instruction execution system, device or apparatus. More specific examples (a non-exhaustive list) of computer readable media include the following: an electrical connection with one or more wires (electronic device), a portable computer disk case (magnetic device), a random access memory (RAM), a read-only memory (ROM), an erasable and programmable read-only memory (EPROM or flash memory), a fiber optic device, and a portable compact disk read-only memory (CDROM).
