Description

Technical Field

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

[0002] Washing machines are one of the most common household appliances today, and the most common washing methods are drum washing machines and pulsator washing machines. However, due to structural limitations, drum washing machines and pulsator washing machines are usually suitable for washing a large number of relatively small clothes or a small number of relatively large clothes at a time. However, due to their large size and weight, they are not convenient to carry and are difficult to use in scenarios such as business trips or travel. Moreover, when on a business trip or traveling, there is usually little demand for washing a large number of small clothes or large clothes in a short period of time. Most of the clothes that need to be washed are small in number and relatively small in size, such as close-fitting underwear, underwear, and vests, short sleeves, shorts, or autumn clothes, autumn trousers, etc. that vary according to the current season.

[0003] In addition, when traveling for business or travel, people usually stay in hotels. Due to factors such as the size of the hotel, some hotels do not have washing machine services. When there is a need for laundry, they can only wash clothes by hand. Not only is the washing effect poor, but the clothes are not easy to dry after washing. If you want to speed up the drying speed, such as using a hair dryer, it is time-consuming and labor-intensive, and it is easy to cause partial undrying, and may damage the service life of the clothes. Or you can go to a self-service laundry, but it may be a long distance and very time-consuming to use. Although some hotels also provide washing machine services, considering that the hotel's washing machine is a public nature after all, it is subject to the frequency, time and intensity of disinfection by the management of the washing machine. The washing machine is likely to contain germs, etc., causing clothing contamination, and then endangering human health, so it is difficult for people to use it with confidence.

[0004] Although there are some related devices for washing small clothes at present, most of these devices are pulsator-type single-washing machines, which easily cause the clothes to be entangled when washing clothes.

[0005] Accordingly, the art requires a new washing control method of a washing machine and a washing machine to solve the above problems existing in the prior art. Summary of the invention

[0044] 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 intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, although the specification describes the shaft extrusion plate 5 and the barrel extrusion plate 6 as fan-shaped bodies, the present invention can obviously adopt other similar means, such as the shaft extrusion plate 5 and the barrel extrusion plate 6 using flat plates, etc., as long as the clothes can be squeezed between the shaft extrusion plate 5 and the barrel extrusion plate 6.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0046] In addition, it should be noted that in the description of the present invention, 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 it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] like Figure 1-2 As shown, Figure 1 is a schematic structural diagram of a washing machine of the present invention, Figure 2 for Figure 1The schematic diagram of the internal structure of the washing machine of the present invention is to solve the problem that the existing related equipment for washing small clothes is difficult to wash clothes of different materials and the clothes are easily entangled when washing clothes. The washing machine of the present invention includes a washing drum 1, which can adopt an internal hollow cylindrical structure, and the washing drum 1 is provided with a delivery port 2, and the delivery port 2 is provided with a delivery cover 3. The washing drum 1 is provided with an axis 4 inside, and one end of the axis 4 extends out of the washing drum 1. The axis extrusion plate 5 is fixed on the axis 4, and the axis extrusion plate 5 is arranged inside the washing drum 1; the inner side of the washing drum 1 is fixed with a barrel extrusion plate 6, and the axis extrusion plate 5 and the barrel extrusion plate 6 can adopt a fan-shaped structure to increase the contact area between the axis extrusion plate 5 and the barrel extrusion plate 6, thereby improving the squeezing effect on the clothes. Through holes can also be set on the axis extrusion plate 5 and the barrel extrusion plate 6 to facilitate squeezing water out of the clothes, thereby improving the washing and dehydration effect of the washing machine on the clothes. A motor 8 is provided outside one end of the washing tub 1. The motor 8 and the end of the shaft 4 extending out of the washing tub 1 are at the same end of the washing tub 1. In order to further improve the driving effect of the motor 8, a reducer can be provided. Driven by the motor 8, the shaft 4 and the washing tub 1 rotate relative to each other. A current detection device 7 is also provided in the washing machine. The current detection device 7 can feed back the current of the motor 8 when the shaft extrusion plate 5 and the barrel extrusion plate 6 contact in different directions to the central processor of the washing machine. The current detection device 7 can be an ammeter, which is provided on the driving circuit of the motor 8.

[0048] The structure of the washing machine of the present invention has been described above. Next, the washing control method of the washing machine of the present invention will be described.

[0049] like Figure 3 As shown, Figure 3 1 is a flow chart of a washing control method of a washing machine of the present invention, and the washing control method of a washing machine comprises the following steps:

[0050] S100, controlling the motor to rotate in a forward direction so that the shaft squeezing plate and the drum squeezing plate squeeze the clothes;

[0051] The direction of the motor's positive rotation can be set in advance. The motor's positive rotation direction can be clockwise or counterclockwise.

[0052] S200, controlling the current detection device to obtain the detection current of the motor;

[0053] The detection current of the motor can be obtained in real time or at a fixed time.

[0054] S300, comparing the detected current with the preset forward current;

[0055] S400: Based on the comparison result, control the rotation direction of the motor.

[0056] The advantage of the above-mentioned arrangement is that in this embodiment, the washing machine forms two washing chambers inside the washing drum through the shaft extrusion plate and the barrel extrusion plate. As the shaft extrusion plate and the barrel extrusion plate squeeze the clothes inside the washing drum, as the force of squeezing the clothes gradually increases, the resistance encountered by the motor when working will also gradually increase accordingly, and the speed of the motor will be reduced, and the current flowing through the motor will increase at this time. Therefore, in this embodiment, by setting the magnitude of two preset currents in different directions, clothes of different materials can be placed in different washing chambers for washing with different squeezing forces. Of course, clothes of the same material can also be placed in two washing chambers for washing, and in this case, it is only necessary to set the magnitude of the two preset currents to the same value. Moreover, since the washing machine adopts the squeezing washing method, it is not easy for clothes to be entangled when washing clothes.

[0057] See below for further reference Figure 3 and Figure 4 , Figure 4 1 is a logic control diagram of the washing control method of the washing machine of the present invention, and describes in detail an embodiment of the washing control method of the washing machine of the present invention.

[0058] In one possible implementation, combining Figure 3 and Figure 4 It can be seen that the specific implementation of "step S200: controlling the current detection device to obtain the detection current of the motor" is:

[0059] S201. Directly obtain the detection current of the motor through the monitoring data of the ammeter.

[0060] In this embodiment, the detection current of the motor can be directly obtained through the ammeter.

[0061] The above introduction has described the method of controlling the current detection device to obtain the detection current of the motor in step S200.

[0062] Return to reference Figure 3 and Figure 4 Regarding “step S400: controlling the rotation direction of the motor based on the comparison result”, the following steps can be adopted:

[0063] S401. When the detected current is ≥ the preset forward current, the motor is controlled to stop rotating for T1 time, and then the motor is controlled to rotate in the reverse direction.

[0064] The T1 time can be set according to actual needs, for example, it can be set to 1-3 seconds.

[0065] S402: When the detected current is less than the preset forward current, the motor continues to be controlled to rotate in the forward direction, and then step S300 is performed again.

[0066] In this embodiment, when the detected current of the motor is greater than or equal to the preset forward current when the motor is rotating in the forward direction, it indicates that the clothes have been squeezed in the forward direction, and the motor is controlled to stop rotating for T1 time. This can not only prevent the washing machine from shortening the service life of the motor due to too frequent changes in direction when washing at high speed, but also allow the washing water to take away as much dirt as possible to achieve the washing effect or remove moisture from the clothes, and then control the motor to rotate in the reverse direction.

[0067] like Figure 4 As shown, after step S400, the washing control method of the washing machine may further include:

[0068] S500: Compare the detected current with the preset reverse current.

[0069] After step S500, the washing control method of the washing machine may further include:

[0070] S601. When the detected current is ≥ the preset reverse current, the motor is controlled to stop rotating for T2 time, and then the motor is controlled to rotate forward.

[0071] The T2 time can also be set according to actual needs, for example, it can also be set to 1-3 seconds. And T2 and T1 can be set to the same or different values.

[0072] S602: When the detected current is less than the preset reverse current, the motor is controlled to continue to rotate in the reverse direction, and then step S500 is executed again.

[0073] In this embodiment, when the detected current of the motor is greater than or equal to the preset reverse current when the motor rotates in the reverse direction, it indicates that the clothes have been squeezed in the reverse direction. The motor is controlled to stop rotating for T2 time. This can not only prevent the washing machine from shortening the service life of the motor due to too frequent changes in rotation direction during high-speed washing, but also allow the washing water to take away as much dirt as possible to achieve the washing effect or remove moisture from the clothes, and then control the motor to rotate forward.

[0074] In the above introduction, a single work flow of the washing control method of the washing machine has been described. Figure 4 As shown, after step S601, the washing control method of the washing machine may further include:

[0075] The step of "step S300: comparing the detected current with the preset forward current" is re-entered until the washing of the washing machine is finished.

[0076] In summary, in the present invention, the washing machine can form two washing chambers inside the washing drum through the shaft extrusion plate and the drum extrusion plate, and can set the magnitude of two preset currents in different directions and the two times when the motor stops rotating in different directions. The clothes can be placed in the two washing chambers for washing or dehydration with different or the same extrusion force according to the material conditions of the clothes, and it is easy to adjust. It is only necessary to adjust and set the magnitude of the preset current and the time when the motor stops rotating. When washing clothes of the same or similar materials, the magnitude of the preset current and the time when the motor stops rotating can be set to the same or slightly different values. When washing clothes with different materials, the magnitude of the preset current in the corresponding direction and the time when the motor stops rotating can be set to a larger or smaller value according to the material conditions to meet the use requirements. In order to further improve the washing effect and dehydration effect of the washing machine, the motor is set to stop rotating for a certain time before changing the direction of rotation, and it can also avoid shortening the service life of the motor due to the frequent change of direction of the motor during high-speed washing, saving the use cost. Moreover, since the washing machine adopts the method of squeezing washing, it is not easy for clothes to be entangled when washing clothes.

[0077] It should be noted that the above-mentioned implementation mode is only used to illustrate the principle of the present invention and is not intended to limit the scope of protection of the present invention. Without departing from the principle of the present invention, those skilled in the art can adjust the above-mentioned structure so that the present invention can be applied to more specific application scenarios.

[0078] For example, in a replaceable embodiment, the clothes can be squeezed between the shaft extrusion plate 5 and the barrel extrusion plate 6. Therefore, the shaft extrusion plate 5 and the barrel extrusion plate 6 recorded in the current specification as fan-shaped bodies can be replaced by shaft extrusion plates 5 and barrel extrusion plates 6 using flat plates, etc. These do not deviate from the principles of the present invention and therefore will fall within the scope of protection of the present invention.

[0079] In addition, the present invention also provides a washing machine, which is the washing machine described in the above technical solution, and the washing machine is configured to be able to execute the washing control method of the washing machine described in any one of the above technical solutions.

[0080] Those skilled in the art can understand that the above-mentioned washing machine also includes some other well-known structures, such as a processor, a controller, a memory, etc., wherein the memory includes but is not limited to a random access memory, a flash memory, a read-only memory, a programmable read-only memory, a volatile memory, a non-volatile memory, a serial memory, a parallel memory or a register, etc., and the processor includes but is not limited to a CPLD / FPGA, a DSP, an ARM processor, a MIPS processor, etc. In order to unnecessarily obscure the embodiments of the present disclosure, these well-known structures are not shown in the drawings.

[0081] Although the various steps in the above embodiment are described in the above-mentioned order, those skilled in the art can understand that in order to achieve the effect of this embodiment, different steps do not have to be executed in such an order. They can be executed simultaneously (in parallel) or in a reverse order. These simple changes are within the scope of protection of the present invention.

[0082] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
