[0046] Some 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 protection scope of the present invention.

The singular terms "one" and "the" may also include plural forms.

[0048] After using the washing machine, detergent condensation or detergent residue usually occurs in the water inlet pipe. Detergent remaining in the water inlet pipe for a long time may cause bacteria to grow in the water inlet pipe, and further, the pipe will be blocked, making it difficult to clean. Mixing old and new detergents will also affect the washing effect of clothes. Existing water inlet pipe cleaning solutions usually require users to manually trigger the cleaning pipe function to clean the water inlet pipe, and the washing machine cannot automatically clean according to the actual situation; there are also water inlet pipe cleaning solutions that require the washing machine to clean the water inlet pipe without running the washing program. This single pipe cleaning solution will cause a lot of energy waste.

[0049] To this end, the present invention provides a method for cleaning the pipes of a washing device, the method comprising: obtaining the indoor temperature and the washing water temperature; controlling the water inlet valve of the washing device based on at least one of the indoor temperature and the washing water temperature to achieve the cleaning of the pipes of the washing device. The present invention first obtains the indoor temperature and the washing water temperature, and controls the water inlet valve of the washing device according to at least one of the obtained indoor temperature and the washing water temperature. The water inlet pipe of the washing device can be cleaned by controlling the water inlet valve so that the washing device can be filled with water multiple times, effectively solving the problem of detergent residue in the water inlet pipe, thereby avoiding the situation where the residual detergent causes the water inlet pipe of the washing device to be blocked and difficult to clean, improving the cleanliness of the water inlet pipe, and avoiding energy waste.

[0050] See attached Figure 1 , Figure 1 It is a flow chart of main steps of a pipeline cleaning method for a washing device according to an embodiment of the present invention.

[0051] like Figure 1 As shown, the pipeline cleaning method of the washing equipment in the embodiment of the present invention mainly includes the following steps S100 to S200.

[0052] Step S100: Acquire the indoor temperature and washing water temperature.

[0053] In this embodiment, when the washing device executes the water inlet program, the indoor temperature is collected by a temperature sensor, and the washing water temperature of the current water inlet pipe is collected by a water temperature sensor installed in the water inlet pipe of the washing device.

[0054] Step S200: controlling a water inlet valve of the washing device based on at least one of the indoor temperature and the washing water temperature to achieve pipe cleaning of the washing device.

[0055] Based on the above steps S100 to S200, the water inlet valve of the washing equipment is controlled according to at least one of the acquired indoor temperature and the washing water temperature. The water inlet valve can be controlled to allow the washing equipment to be filled with water multiple times, so that the water inlet pipe of the washing equipment can be flushed and cleaned, thereby effectively solving the problem of detergent residue in the water inlet pipe, thereby avoiding the situation where the water inlet pipe of the washing equipment is blocked and difficult to clean due to residual detergent, thereby improving the cleanliness of the water inlet pipe and avoiding energy waste.

[0056] The above steps S100 and S200 are further described below.

[0057] For step S100, the indoor temperature and the washing water temperature are acquired.

[0058] In this embodiment, when the washing device executes the water inlet program, the indoor temperature is collected by a temperature sensor, and the washing water temperature of the current water inlet pipe is collected by a water temperature sensor installed in the water inlet pipe of the washing device.

[0059] With respect to step S200, in one embodiment, the washing water temperature includes a first washing water temperature in the washing stage, and the water inlet valve of the washing equipment includes a first water inlet valve; controlling the water inlet valve of the washing equipment based on at least one of the indoor temperature and the washing water temperature includes: determining the number of times the first water inlet valve is opened based on the indoor temperature and / or the first washing water temperature; and controlling the first water inlet valve based on the number of times the first water inlet valve is opened.

[0060] Specifically, the washing device includes at least two water inlets, one of which is a washing water inlet and the other is a rinsing water inlet. The first washing water temperature is the water temperature collected at the washing water inlet when the washing device is running the washing phase water inlet program. The first water inlet valve is a valve for controlling water inlet in the washing water inlet pipeline. In this embodiment, the number of openings of the washing program water inlet valve is determined according to the indoor temperature and / or the water inlet temperature of the washing program, and the washing program water inlet valve is controlled according to the number of openings. When the water temperature or room temperature meets the preset conditions, the number of water inlet in the washing program can be increased, thereby flushing the detergent in the water inlet pipeline.

[0061] In one embodiment, the number of times the first water inlet valve is opened is determined based on the indoor temperature and / or the first washing water temperature, including: when the indoor temperature is less than a preset temperature threshold, calculating a first temperature difference between a preset temperature threshold and the indoor temperature; determining the number of times the first water inlet valve is opened based on the first temperature difference and a first corresponding relationship, wherein the first corresponding relationship is a corresponding relationship between the first temperature difference and the number of times the first water inlet valve is opened.

[0062] Specifically, when the indoor temperature is lower than the preset temperature threshold, it is determined that the detergent may be incompletely diluted and condensed in the water inlet pipe due to the low room temperature. At this time, the first temperature difference between the preset temperature threshold and the indoor temperature is calculated, and the number of times the first water inlet valve is opened is determined based on the first temperature difference and the first corresponding relationship. The first corresponding relationship is the corresponding relationship between the first temperature difference and the number of times the water inlet valve is opened based on offline experiments. The number of times the water inlet valve is opened is controlled based on the temperature difference between the room temperature and the preset temperature threshold, and the residual detergent in the water inlet pipe can be rinsed clean by multiple flushing without affecting the normal operation of the washing program. It is highly practical and saves energy consumption.

[0063] In one technical solution, the number of times the first water inlet valve is opened is determined based on the indoor temperature and / or the first washing water temperature, including: when the first washing water temperature is lower than a preset temperature threshold, calculating a second temperature difference between the preset temperature threshold and the first washing water temperature; determining the number of times the first water inlet valve is opened based on the second temperature difference and a second corresponding relationship, wherein the second corresponding relationship is a corresponding relationship between the second temperature difference and the number of times the first water inlet valve is opened.

[0064] In this embodiment, when the first washing water temperature is less than the preset temperature threshold, it is determined that the current washing water temperature is too low and the detergent in the water inlet pipe may not be completely diluted. Therefore, the second temperature difference between the preset temperature threshold and the first washing water temperature is calculated, and the number of openings of the first water inlet valve is determined based on the second temperature difference and the second corresponding relationship. The second corresponding relationship is the corresponding relationship between the second temperature difference and the number of openings of the first water inlet valve determined by offline experiments, and then the first water inlet valve is controlled based on the number of openings of the first water inlet valve. The number of openings of the water inlet valve is controlled based on the temperature difference between the inlet water temperature and the preset temperature threshold, so that the residual detergent in the water inlet pipe can be rinsed clean by multiple flushing when the water temperature is low.

[0065] In one technical scheme, the number of times the first water inlet valve is opened is determined based on the indoor temperature and / or the first washing water temperature, including: when the indoor temperature is lower than a preset temperature threshold, calculating a first temperature difference between the preset temperature threshold and the indoor temperature; when the first washing water temperature is lower than the preset temperature threshold, calculating a second temperature difference between the preset temperature threshold and the first washing water temperature; determining the maximum value between the first temperature difference and the second temperature difference; determining the number of times the first water inlet valve is opened based on the maximum value and a third corresponding relationship, wherein the third corresponding relationship is a corresponding relationship between the maximum value and the number of times the first water inlet valve is opened.

[0066] Specifically, when both the indoor temperature and the first washing water temperature are less than the preset temperature threshold, the first temperature difference between the preset temperature threshold and the indoor temperature, the second temperature difference between the preset temperature threshold and the first washing water temperature are calculated, and the maximum value of the two temperature differences is determined. The number of times the first water inlet valve is opened is determined based on the maximum value and the third corresponding relationship, and the first water inlet valve is controlled according to the determined number of times the first water inlet valve is opened. It can be understood that when the maximum value is the first temperature difference, the first corresponding relationship is used as the third corresponding relationship; when the maximum value is the second temperature difference, the second corresponding relationship is used as the third corresponding relationship. The number of times the water inlet valve is opened is determined based on the maximum value in the temperature difference, so that when the indoor temperature and the water inlet temperature differ greatly, more flushing times can be obtained according to a lower temperature to achieve the best cleaning effect.

[0067] In one technical solution, the washing water temperature includes a second washing water temperature in the rinsing stage, and the water inlet valve of the washing equipment includes a second water inlet valve; the water inlet valve of the washing equipment is controlled based on at least one of the indoor temperature and the washing water temperature, including: when the indoor temperature is lower than a preset temperature threshold, calculating a first temperature difference between a preset temperature threshold and the indoor temperature; and / or when the second washing water temperature is lower than a preset temperature threshold, calculating a third temperature difference between a preset temperature threshold and the second washing water temperature; determining the number of times the second water inlet valve is opened based on the first temperature difference and / or the third temperature difference; and controlling the second water inlet valve based on the number of times the second water inlet valve is opened.

[0068] In this embodiment, the washing machine includes at least two water inlets, one of which is a washing water inlet and the other is a rinsing water inlet. The second washing water temperature is the washing water temperature collected by the water temperature sensor at the rinsing water inlet when the washing device is running to the water inlet program of the rinsing stage, and the second water inlet valve is a valve for controlling water inlet in the rinsing water inlet pipeline.

[0069] In this embodiment, when the washing machine is running to the water inlet program of the rinsing stage, if the indoor temperature is lower than the preset temperature threshold, it is determined that the softener may be diluted and incompletely condensed in the water inlet pipe due to the low room temperature, and the first temperature difference between the preset temperature threshold and the indoor temperature is calculated, and the number of times the second water inlet valve is opened is determined based on the first temperature difference and the first corresponding relationship, which is the corresponding relationship between the first temperature difference and the number of times the water inlet valve is opened based on offline experiments. The number of times the water inlet valve is opened is controlled based on the temperature difference between the room temperature and the preset temperature threshold, so that the residual softener in the water inlet pipe can be rinsed clean by multiple flushing without affecting the normal operation of the washing machine.

[0070] In this embodiment, when the washing device runs to the water inlet program of the rinsing stage, when the second washing water temperature is less than the preset temperature threshold, it is determined that the current washing water temperature is too low and the softener in the water inlet pipeline may not be completely diluted, and the third temperature difference between the preset temperature threshold and the second washing water temperature is calculated, and the number of times the second water inlet valve is opened is determined based on the third temperature difference and the fourth corresponding relationship, and the fourth corresponding relationship is the corresponding relationship between the third temperature difference and the number of times the second water inlet valve is opened determined by offline experiments, and then the second water inlet valve is controlled based on the number of times the second water inlet valve is opened. The number of times the water inlet valve is opened is controlled based on the temperature difference between the water inlet temperature and the preset temperature threshold, so that the residual softener in the water inlet pipeline can be rinsed clean by flushing water multiple times when the water inlet temperature is low, thereby avoiding the growth of bacteria after the softener is attached and affecting the washing effect of the clothes.

[0071] In this embodiment, when the washing device runs to the water inlet program of the rinsing stage, when the indoor temperature and the second washing water temperature are both less than the preset temperature threshold, the first temperature difference between the preset temperature threshold and the indoor temperature, the third temperature difference between the preset temperature threshold and the second washing water temperature are calculated, and the maximum value of the two temperature differences is determined, and the number of openings of the second water inlet valve is determined based on the maximum value and the fifth corresponding relationship, and the second water inlet valve is controlled according to the determined number of openings of the second water inlet valve. It can be understood that when the maximum value is the first temperature difference, the first corresponding relationship is used as the fifth corresponding relationship; when the maximum value is the third temperature difference, the fourth corresponding relationship is used as the fifth corresponding relationship.

[0072] In one technical solution, the method further includes: when the indoor temperature and the washing water temperature are both lower than a preset temperature threshold and the washing device has run to the last drainage stage, controlling the washing device to open a first water inlet valve and a second water inlet valve; when the opening time of the first water inlet valve and the second water inlet valve reaches a preset time, controlling the washing device to close the first water inlet valve and the second water inlet valve.

[0073] Specifically, when the indoor temperature and the first washing water temperature and the second washing water temperature are all lower than the preset temperature threshold, when the washing device runs to the final drainage stage, the washing water inlet valve and the rinsing water inlet valve are opened, and the washing device is controlled to drain water while taking in water, and the detergent and softener remaining in the water inlet pipe are rinsed clean. When the water inlet valve is opened for a preset time, the washing device is controlled to close the first water inlet valve and the second water inlet valve, and the preset time can be set to 10 seconds. By opening the water inlet valve in the final drainage stage, the detergent and softener remaining in the water inlet pipe can be completely rinsed clean, avoiding the problem of bacteria breeding in the water inlet pipe due to the mixing of new and old detergents or long-term residue, and further improving the cleaning effect of the water inlet pipe.

[0074] See attached Figure 2 , Figure 2 It is a complete step flow chart of a pipeline cleaning method for a washing device according to an embodiment of the present invention.

It can be understood that when the maximum value is the first temperature difference, the first corresponding relationship is used as the third corresponding relationship; when the maximum value is the second temperature difference, the second corresponding relationship is used as the third corresponding relationship.

[0088] Step S213: controlling the first water inlet valve based on the number of times the first water inlet valve is opened.

[0089] Step S214: When the washing machine performs the water inlet procedure of the rinsing stage, the indoor temperature and the second washing water temperature are obtained.
