[0002] Most families use a washing machine with a relatively large capacity to wash the clothes of the whole family. However, washing underwear, outerwear, and baby clothes together not only poses a risk of cross-infection of germs, but also there is a waste phenomenon such as waste water and electricity when washing single or small pieces of clothes. With the improvement of people's living standards, many people want to wash underwear and outerwear separately, but buying another washing machine takes up a lot of space and is inconvenient. Therefore, mini washing machines for washing small pieces of clothes have emerged in the existing market.

[0003] A normal washing machine directly injects water into the drum, and sensors and the like are arranged in the drum to directly detect the amount of water injected into the drum. When the required amount of water is reached, the water injection into the drum is stopped.

[0004] However, for a mini washing machine, it needs to be taken to the tabletop when in use, but there may not be a water source on the tabletop. Therefore, a detachable water tank needs to be installed on the mini washing machine. When in need of use, it stores enough water for the laundry components to wash clothes. A water level detector needs to be installed in the detachable water tank to detect whether the stored water volume is sufficient.

[0005] The drum of the mini washing machine is small and there is not enough space to install a water level detection device; and installing a water level detection device in a small drum, due to the small water volume and volume, the water level detection accuracy is not enough. Therefore, a new water level detection method is needed for the miniaturized washing machine to solve the problem of detecting the water volume in the drum. Summary of the Invention

[0055] The control method for a mini washing machine based on water volume detection provided by the present invention is toFigure 1-2 is based on the washing machine in it.

[0056] Embodiment 1:

[0057] As Figure 3 shown, a control method for a mini washing machine based on water volume detection according to the present invention includes:

[0058] S100. Obtain a first water volume value in the water tank, where the first water volume value is used to represent the position information when the water inlet valve connecting the water tank to the drum is opened; wherein, the water tank is used to supply water to the drum, and a water inlet valve is provided between the water tank and the drum;

[0059] S200. Obtain a second water volume value in the water tank, where the second water volume value is used to represent the position information when the water inlet valve connecting the water tank to the drum is closed;

[0060] S300. Match the executable program or parameters of the mini washing machine according to the difference between the first water volume value and the second water volume value.

[0061] Referring to Figure 4 , in this embodiment, obtaining the first water volume value in the water tank in step S100 includes:

[0062] S110. Obtain the feedback signals of i water level detectors installed at i water volume levels in the water tank; wherein, i = 1, 2,..., N, N is an integer, and N ≥ 1; each water volume level corresponds to a water volume value.

[0063] S120. Obtain the first water volume value X when the water inlet valve is opened according to the feedback signals of the i water level detectors at the i water volume levels i .

[0064] It can be understood that in this embodiment, there are i water volume levels in the water tank, and a water level detector is installed at each water volume level, that is, i water level detectors are installed at i water volume levels, and each water volume level corresponds to a water volume value.

[0065] The water level detector at this time can be an infrared sensor or a water level probe. For a mini washing machine, while ensuring low cost, ensuring more functions becomes the research and development focus of the mini washing machine. The cost of the water level probe and the infrared sensor is relatively low, and through the logical judgment process, it can be determined whether there is water at a certain water volume level according to the output signal 1 or 0.

[0066] For example: when the water level detector is a water level probe, when the water level detector at the i-th water volume level has a feedback signal, it outputs 1, that is, there is water at this water level detector; when the water level detector at the i-th water volume level has no feedback signal, it outputs 0, that is, there is no water at this water level detector.

[0067] When the water level detector is an infrared sensor, when the water level detector at the i-th water volume level has a feedback signal, it outputs 0, indicating that there is no water at this water level detector; when the water level detector at the i-th water volume level has no feedback signal, it outputs 1, indicating that there is water at this water level detector. This feedback signal is determined by the principle of the water level probe and the infrared sensor, which will not be elaborated here. Uniformly, in this embodiment, based on the simple output signal, it can be determined whether there is water at the water level detector of the i-th water volume level based on PLC control.

[0068] Therefore, step S120 obtains the first water volume value X when the water inlet valve is opened according to the feedback signals of the i water level detectors at the i water volume levels i , including:

[0069] S121. When the water level detector at the (i - n - 1)-th water volume level outputs a feedback signal indicating water and the water level detector at the (i - n)-th water volume level outputs a feedback signal indicating no water, it is obtained that the water volume value corresponding to the (i - n)-th water volume level > the first water volume value X i ≥ the water volume value corresponding to the (i - n - 1)-th water volume level; where the water level detector is a water level probe or an infrared sensor, n≥0. Obtaining the second water volume value in the water tank in step S200 includes:

[0070] S210. When the water in the water tank reaches the (i - m)-th water volume level, the water inlet valve connecting the water tank to the drum is closed; m≥1;

[0071] The water volume value corresponding to the (i - m)-th water volume level is the second water volume value Y i .

[0072] Step S300 matches the executable programs or parameters of the mini washing machine according to the difference between the first water volume value and the second water volume value, including:

[0073] S310. According to the first water volume value X i range and the second water volume value Y i it is obtained that: the drum water volume value ≥ the water volume value corresponding to the (i - n - 1)-th water volume level minus the water volume value corresponding to the (i - m)-th water volume level; match the executable programs or parameters of the mini washing machine according to the drum water volume value.

[0074] Among them, the executable programs or parameters include: executable washing, rinsing and other programs or parameters such as the input amount of washing powder, washing time, washing times, rinsing time, rinsing times, etc.

[0075] The application scenario of this embodiment is: 3 water level detectors at 3 water volume levels are installed in the water tank, refer to Figure 2, the three water level detectors are the third water level probe 251, the second water level probe 252, and the first water level probe 253, and the corresponding water volume levels are the third water volume level, the second water volume level, and the first water volume level.

[0076] At this time, i is 3, n is 0, and m is 2. When the second water level probe 252 of the second water volume outputs 1, that is, outputs a water feedback signal, and the third water level probe 251 of the third water volume level outputs 0, that is, outputs a no-water feedback signal, the water volume value corresponding to the third water volume level > the first water volume value X i ≥ the water volume value corresponding to the second water volume level; that is, the first water volume value X i is between the third water level probe 251 and the second water level probe 252.

[0077] When the water in the water tank reaches the first water volume level, the water inlet valve connecting the water tank to the drum is closed, and the water volume value corresponding to the first water volume level is the second water volume value Y i， According to the first water volume value X i range and the second water volume value Y i It is obtained that: the water volume value corresponding to the third water volume level minus the water volume value corresponding to the second water volume level > the drum water volume value ≥ the water volume value corresponding to the second water volume level minus the water volume value corresponding to the first water volume level, and the executable program or parameters of the mini washing machine are matched according to the drum water volume value.

[0078] In this embodiment, a water level probe or an infrared sensor with a lower price is installed in the detachable water tank. Without installing a water level detection device in the drum, the water volume range in the drum can be detected; not only can the water level range in the detachable water tank be detected to remind the user to add water, etc., but also the water volume in the drum can be obtained according to the water level in the detachable water tank, so as to match the executable washing, rinsing and other programs of the washing machine, or the parameter settings such as the amount of washing powder to be put and the washing time.

[0079] Embodiment 2:

[0080] As Figure 5 shown, a control method for a mini washing machine based on water volume detection according to the present invention includes:

[0081] S100. Obtain the first water volume value in the water tank, where the first water volume value is used to characterize the position information when the water inlet valve connecting the water tank to the drum is opened; wherein, the water tank is used to supply water to the drum, and a water inlet valve is provided between the water tank and the drum;

[0082] S200. Obtain the second water volume value in the water tank, where the second water volume value is used to characterize the position information when the water inlet valve connecting the water tank to the drum is closed;

[0083] S300. Match the executable programs or parameters of the mini washing machine according to the difference between the first water volume value and the second water volume value.

[0084] In this embodiment, obtaining the first water volume value in the water tank in step S100 includes:

[0085] S110. Obtain the feedback signals of i water level detectors installed at i water volume levels in the water tank; where i = 1, 2,..., N, N is an integer, and N ≥ 1;

[0086] S120. Obtain the first water volume value X when the water inlet valve is opened according to the feedback signals of the i water level detectors at the i water volume levels. i .

[0087] It can be understood that in this embodiment, there are i water volume levels in the water tank, and a water level detector is installed at each water volume level, that is, i water level detectors are installed at i water volume levels, and each water volume level corresponds to a water volume value.

[0088] At this time, the water level detector can be an infrared sensor or a water level probe. For a mini washing machine, while ensuring low cost, ensuring more functions becomes the research and development focus of the mini washing machine. The water level probe and the infrared sensor have low costs. Through a logical judgment process, it can be determined whether there is water at a certain water volume level according to the output signal 1 or 0.

[0089] For example: when the water level detector is a water level probe, when there is a feedback signal from the water level detector at the i-th water volume level, output 1, that is, there is water at this water level detector; when there is no feedback signal from the water level detector at the i-th water volume level, output 0, that is, there is no water at this water level detector.

[0090] When the water level detector is an infrared sensor, when there is a feedback signal from the water level detector at the i-th water volume level, output 0, that is, there is no water at this water level detector; when there is no feedback signal from the water level detector at the i-th water volume level, output 1, that is, there is water at this water level detector. This feedback signal is determined by the principles of the water level probe and the infrared sensor, and will not be elaborated here. Generally, in this embodiment, based on the simple output signal and PLC control, it can be determined whether there is water at the water level detector at the i-th water volume level.

[0091] Therefore, step S120 obtains the first water volume value X when the water inlet valve is opened according to the feedback signals of the i water level detectors at the i water volume levels. i , including:

[0092] S122. When the water level detector at the (i - n - 1)-th water volume level outputs a feedback signal indicating water and the water level detector at the (i - n)-th water volume level outputs a feedback signal indicating no water, the water volume value corresponding to the (i - n)-th water volume level is obtained as > the current water level value ≥ the water volume value corresponding to the (i - n - 1)-th water volume level; that is, it is obtained that the water in the water tank is between the water level detector at the (i - n - 1)-th water volume level and the water level detector at the (i - n)-th water volume level.

[0093] When the water in the water tank is between the water level detector at the (i - n - 1)-th water volume level and the water level detector at the (i - n)-th water volume level, open the drain valve between the drain pipe and the water tank, where n ≥ 0.

[0094] When the water in the water tank reaches the (i - n - 1)-th water volume level, close the drain valve between the drain pipe and the water tank, and open the water inlet valve connecting the water tank to the drum; at this time, the first water volume value X i = the water volume value corresponding to the (i - n - 1)-th water volume level.

[0095] Obtaining the second water volume value in the water tank in step S200 includes:

[0096] S210. When the water in the water tank reaches the (i - m)-th water volume level, close the water inlet valve connecting the water tank to the drum; where m ≥ 1.

[0097] The water volume value corresponding to the (i - m)-th water volume level is the second water volume value Y i .

[0098] Step S300 matches the executable programs or parameters of the mini washing machine according to the difference between the first water volume value and the second water volume value, including:

[0099] S320. According to the first water volume value X i and the second water volume value Y i it is obtained that: the drum water volume value = the water volume value corresponding to the (i - n - 1)-th water volume level minus the water volume value corresponding to the (i - m)-th water volume level; match the executable programs or parameters of the mini washing machine according to the drum water volume value.

[0100] Among them, the executable programs or parameters include: executable washing, rinsing and other programs or parameters such as the input amount of washing powder, washing time, number of washing times, rinsing time, number of rinsing times, etc.

[0101] The application scenario of this embodiment is: 3 water level detectors at 3 water volume levels are installed in the water tank. Referring to Figure 2 , the 3 water level detectors are the third water level probe 251, the second water level probe 252, and the first water level probe 253 respectively, and the corresponding water volume levels are the third water volume level, the second water volume level, and the first water volume level. One water volume level corresponds to one water volume value.

[0102] At this time, i is 3, n is 0, and m is 2. When the second water level probe 252 of the second water volume outputs 1, that is, outputs a water feedback signal, and the third water level probe 251 of the third water volume gear outputs 0, that is, outputs a no-water feedback signal, it is obtained that the water volume value corresponding to the third water volume gear > the current water level value ≥ the water volume value corresponding to the second water volume gear; at this time, the drain valve between the drain pipe and the water tank is opened to drain a certain amount of water.

[0103] After draining a certain amount of water, when the water in the water tank reaches the second water volume gear, the drain valve between the drain pipe and the water tank is closed, and the water inlet valve connecting the water tank to the drum is opened to introduce water into the drum. The first water volume value X at this time i is equal to the water volume value corresponding to the second water volume gear, that is, the water volume where the second water level probe 252 is located.

[0104] Water is injected into the drum through the water inlet valve. When the water in the water tank reaches the first water volume gear, the water inlet valve connecting the water tank to the drum is closed, and the water volume value corresponding to the first water volume gear is the second water volume value Y i， According to the first water volume value X i range and the second water volume value Y i It is obtained that: the drum water volume value = the water volume value corresponding to the second water volume gear minus the water volume value corresponding to the first water volume gear, and the executable program or parameters of the mini washing machine are matched according to the drum water volume value.

[0105] In this embodiment, a water level probe or an infrared sensor with a relatively low price is installed in the detachable water tank. Without installing a water level detection device in the drum, the water volume range in the drum can be detected; not only can the water level range in the detachable water tank be detected to remind the user to add water, etc., but also the water volume in the drum can be obtained according to the water level in the detachable water tank, so as to match the executable washing, rinsing and other programs of the washing machine, or set parameters such as the dosage of washing powder and washing time according to the water volume in the drum.

[0106] Embodiment 3:

[0107] As Figure 6 shown, the mini washing machine control method based on water volume detection provided by the present invention includes:

[0108] S100. Obtain the first water volume value in the water tank, where the first water volume value is used to characterize the position information when the water inlet valve connecting the water tank to the drum is opened; wherein, the water tank is used to supply water to the drum, and a water inlet valve is provided between the water tank and the drum;

[0109] S200. Obtain the second water volume value in the water tank, where the second water volume value is used to characterize the position information when the water inlet valve connecting the water tank to the drum is closed;

[0110] S300. Match the executable programs or parameters of the mini washing machine according to the difference between the first water volume value and the second water volume value.

[0111] Step S100 of obtaining the first water volume value in the water tank includes:

[0112] S130. When the water inlet valve connecting the water tank to the drum is opened, obtain the first state information of the float in the water tank;

[0113] S140. Obtain the first height and / or the first water volume value of the float according to the first state information.

[0114] Step S200 of obtaining the second water volume value in the water tank includes:

[0115] S220. When the water inlet valve connecting the water tank to the drum is closed, obtain the second state information of the float in the water tank;

[0116] S230. Obtain the second height and / or the second water volume value of the float according to the second state information.

[0117] In this embodiment, the water level detector installed in the water tank includes a float and a microprocessor arranged in the water tank. The float can float up and down with the water level in the water tank. According to the state information such as water pressure and buoyancy at the position of the float and the difference in signal transmission time, the height where the float is located is obtained. Therefore, the first state information and the second state information can be the water pressure information, buoyancy information, signal transmission time information, etc. of the float. The microprocessor obtains the first height of the float according to the first state information, and then obtains the first water volume value according to the first height of the float.

[0118] Taking the signal transmission time information as an example, the float is located in the water tank. An infrared integrated module is provided at the bottom of the water tank. A reflective sheet is provided on the side of the float facing the integrated module. A layer of light-transmitting plate is provided at the connection between the infrared integrated module and the water tank. Infrared rays are reflected in the water by means of the light-transmitting plate. The infrared integrated module receives the infrared rays reflected by the reflective sheet of the float and outputs a signal to the microcontroller.
