DETAILED DESCRIPTION

[0033] 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.

[0035] 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.

[0036] The quality of washing water is usually determined by the local water quality. In areas where the water source is polluted to some extent, the pH value is often not suitable for direct washing.

[0037] In view of this, if Figure 1-2 As shown, the present invention provides a control method for a clothes processing device, wherein a dispenser box of the clothes processing device comprises a first alkaline delivery area, a neutral delivery area and a first acid delivery area;

[0038] During the water intake process in the washing stage, the clothing treatment device detects the pH value of the external water source and controls the corresponding area of ​​the dispenser box to dispense to adjust the pH of the washing water to a set range, wherein the first alkaline dispensing area is used to store alkaline clothing treatment agent, the neutral dispensing area is used to store neutral clothing treatment agent, and the first acidic dispensing area is used to store acidic clothing treatment agent.

[0039] When the pH value of the external water source is relatively high, the laundry treatment device controls the first acidic delivery area to deliver an acidic laundry treatment agent to adjust the pH value of the washing water to within a set range. The setting range of the pH value of the washing water in the present invention is preferably 7-8;

[0040] When the pH value of the external water source is just within the set range, the clothing treatment device controls the neutral delivery area to deliver a neutral clothing treatment agent to avoid affecting the pH value of the washing water;

[0041] When the pH value of the external water source is relatively low, the laundry treating apparatus controls the first alkaline delivery zone to deliver an alkaline laundry treating agent to adjust the pH value of the washing water to within a set range.

[0042] Specifically, Figure 2 As shown, a first sensor 1 for detecting the pH value of an external water source is provided on the water inlet pipe 6 of the laundry processing device. Figure 2 The direction of the middle arrow is the direction of water flow. After the water from the external water source passes through the first sensor 1, the large particles of impurities are filtered by the filter 2, and then enter the inner drum 4. The second sensor 5 arranged in the inner drum 4 is used to detect the pH value of the washing water.

[0043] In one embodiment of the present invention, the water inflow from the external water source and the amount of clothing treatment agent added are determined based on the weight of the clothing. That is, when the clothing is placed in the clothing treatment device, the water inflow from the external water source and the amount of clothing treatment agent added are already determined. At this time, the pH value of the washing water after the external water source and the clothing treatment agent are mixed is predictable.

[0044] When the pH value of the washing water exceeds the set range, that is, the clothing treatment device adds corresponding clothing treatment agents according to the pH value of the external water source, but the pH value of the washing water is still not within the set range, the clothing treatment device controls the dispenser box to add additional clothing treatment agents to adjust the pH of the washing water to within the set range.

[0045] As the amount of laundry treatment agent added increases, the foam generated during the washing process will also increase, and foam overflow may occur. To avoid foam overflow, the laundry treatment device in this embodiment monitors the height of the drum in real time when detecting the addition of additional laundry treatment agent, and the height of the drum is the sum of the foam height and the height of the washing water in the drum.

[0046] The clothes processing device detects whether the height inside the drum reaches the set height. If so, the spray unit is started to lower the height inside the drum; if not, a preset program is executed.

[0047] Although spraying can reduce the height of the drum, it will also increase the height of the washing water. In order to reduce the height of the drum after spraying, a water pump is also provided at the bottom of the clothes processing device in this embodiment. The spray unit is provided at the upper part of the inner drum 4. The water pump is used to pump the washing water in the inner drum 4 to the spray unit, and then the spray unit sprays the washing water from the upper part of the inner drum 4 into the inner drum 4 to eliminate the foam in the inner drum 4. The above-mentioned spraying method can avoid the increase of the height of the washing water in the inner drum 4, and can also avoid the pH value of the external water source affecting the pH value of the current washing water when water is drawn from the external water source to the spray unit, thereby affecting the washing effect.

[0048] In another embodiment of the present invention, when the clothing processing device detects that the spray unit is started during the washing stage, in order to ensure the washing effect, the user is asked within the first set time before the end of the washing stage whether to add the washing time that is the same as the spraying time. If so, the washing time is added; if not, the preset program is executed, that is, the rinsing stage is directly entered.

[0049] When the clothing processing device asks the user, it determines whether the ratio of the current washing time to the theoretical washing time is greater than the first set value. If so, the clothing processing device determines that the current washing time is sufficient to ensure the washing effect. In order to ensure that the washing is completed within the preset time, it is recommended to directly execute the preset program; if not, the clothing processing device determines that the current washing time is insufficient to ensure the washing effect. In order to ensure the washing effect, it is recommended to add the washing time that is the same as the spraying time.

[0050] For example, the theoretical washing time is 25 minutes, the first set time is 5 minutes, and the time allocation when the clothing processing device asks the user is 2 minutes for spraying and 18 minutes for washing. At this time, the ratio of the current washing time to the theoretical washing time is 18 / 25=0.72. If the first set value is determined to be 0.7, the ratio of the current washing time to the theoretical washing time is greater than the first set value. The clothing processing device determines that the current washing time can ensure the washing effect. In order to complete the washing within the preset time, it is recommended that the user directly execute the preset program; if the time allocation when the clothing processing device asks the user is 5 minutes for spraying and 15 minutes for washing, the ratio of the current washing time to the theoretical washing time is 15 / 25=0.6, which is less than the first set value 0.7. The clothing processing device determines that the current washing time is insufficient to ensure the washing effect, and recommends the user to add the same washing time as the spraying time.

[0051] In this embodiment, the user is asked whether to add washing time within the first set time before the end of the washing stage. The washing time equal to the spraying time can be added to ensure the washing effect. If the user's subsequent arrangements are relatively tight, in order to avoid affecting the user's subsequent arrangements, the washing time can be not added and the rinse stage can be directly entered to complete the washing within the preset time.

[0052] In this embodiment, the clothing processing device can interact with the user through an APP associated with the clothing processing device on the user's mobile phone. The clothing processing device can push relevant information to the user through the APP to ask the user, and the user can also operate on the APP interface to select additional washing time or directly execute the preset program.

[0053] If the clothing processing device does not receive user feedback at the end of the washing stage, it determines whether to supplement the washing time equal to the spraying time according to the ratio of the current washing time to the theoretical washing time at the end of the washing stage.

[0054] Specifically, when the ratio of the current washing time to the theoretical washing time is greater than a first set value, the clothes processing device determines that the current washing time is sufficient to ensure the washing effect, and there is no need to supplement the washing time, and the preset program can be directly executed;

[0055] When the ratio of the current washing time to the theoretical washing time is less than or equal to the first set value, the clothing processing device determines that the current washing time is insufficient to ensure the washing effect. In order to ensure the user experience, it supplements the washing time equal to the spraying time and then executes the preset program.

[0056] Furthermore, when the clothes treating device adds additional clothes treating agent, in order to ensure the rinsing effect, the clothes treating device increases the number of rinsing times according to the ratio of the amount of the additional clothes treating agent added to the theoretical amount of the clothes treating agent added.

[0057] When the clothes processing device detects that the pH value of the current washing water is within the set range, the distributor box is controlled to adjust the current delivery area to the neutral delivery area.

[0058] For example, the pH value of the external water source is relatively small, and the alkaline clothing treatment agent is added to the first alkaline delivery area of ​​the clothing treatment equipment to adjust the pH value of the washing water to the set range. However, when part of the alkaline clothing treatment agent is added, the pH value of the washing water has been adjusted to the set range. If the alkaline clothing treatment agent continues to be added, the pH value of the washing water will be too large, affecting the washing effect. At this time, the clothing treatment equipment adjusts the current delivery area to the neutral delivery area, that is, continues to add neutral clothing treatment agent to ensure the delivery amount of clothing treatment agent, and at the same time, the pH value of the washing water is kept within the set range.

[0059] If the pH value of the washing water is adjusted only by using clothing treatment agent, during the rinsing stage, there is no need to continue adding clothing treatment agent, and the water from the external water source directly contacts the clothes. If the pH value of the external water source is high, it may still affect the washing effect of the clothes. For example, rinsing water with a high pH value is not suitable for rinsing clothes made of materials such as wool.

[0060] Therefore, in another embodiment of the present invention, the clothing processing device is further provided with a second alkaline delivery area and a second acid delivery area. During the rinsing stage, the clothing processing device detects the pH value of the external water source and controls the operation of the corresponding delivery area to adjust the pH value of the rinsing water to within a set range.

[0061] The second alkaline addition area is provided with alkaline substances such as baking soda to neutralize the external water source with a lower pH, and the second acidic addition area is provided with acidic substances to neutralize the external water source with a higher pH. For the external water source whose pH is within the set range, there is no need to neutralize it and it can be directly used in the rinsing stage of clothes.

[0062] Furthermore, the clothes processing device in this embodiment is also provided with a microorganism sensor 3 for detecting the microorganism concentration of the external water source;

[0063] During the last rinse of the preset program, the clothes treating device performs a sterilization program according to the feedback information of the microorganism sensor 3 .

[0064] like Figure 2 As shown, a first sensor 1 for detecting the pH value of an external water source, a filter screen 2, and a microbial sensor 3 for detecting the concentration of microorganisms in the external water source are sequentially arranged on the water inlet pipe 6 of the clothing treatment equipment. The water flows into the inner drum 4 through the first sensor 1, the filter screen 2 and the microbial sensor 3 in sequence. The second sensor 5 in the inner drum 4 detects the pH value of the washing water to determine whether it is necessary to add additional clothing treatment agent or switch the addition area to the neutral addition area.

[0065] Considering that the external water source contains microorganisms, if the sterilization program is started earlier, the subsequent rinsing stage will still use the external water source, and the microorganisms therein may still contaminate the clothes in the drum. Therefore, the present invention only performs the sterilization program during the last rinse.

[0066] In one embodiment of the present invention, the sterilization program may use ozone sterilization. To avoid the ozone concentration being harmful to the user at the end of washing, in this embodiment, the clothing processing device reminds the user to pick up the clothes if and only if the washing process is completed and the clothing processing device determines that the ozone concentration has dropped to a safe concentration.

[0067] Alternatively, in another embodiment of the present invention, the sterilization program may also be set to sterilization with a disinfectant, that is, adding a disinfectant into the rinse water. In this embodiment, the clothing processing device is further provided with an olfactory sensor to detect the concentration of the remaining disinfectant.

[0068] When the clothing processing equipment detects that the disinfectant concentration is less than or equal to the set concentration, it directly executes the preset program, that is, the rinsing stage ends and enters the dehydration stage.

[0069] When the clothing processing equipment detects that the disinfectant concentration is greater than the set concentration, the number of rinses is increased based on the difference between the current concentration and the set concentration on the basis of the preset program number of rinses to reduce the disinfectant concentration and avoid affecting the user experience. At this time, the microorganisms in the rinse water can consume the remaining disinfectant to reduce the disinfectant concentration. When the clothing processing equipment discharges the rinse water, the remaining disinfectant can also be discharged together, thereby further reducing the disinfectant concentration.

[0070] Since the present invention is provided with a first acidic delivery area, a neutral delivery area, and a first alkaline delivery area, in order to avoid insufficient inventory of clothing treatment agent affecting the user's normal washing, the clothing treatment device in the present invention determines the reminder threshold of the clothing treatment agent according to the logistics days, the frequency of use, and the single delivery amount. When the inventory of clothing treatment agent is less than or equal to the reminder threshold, the clothing treatment device reminds the user.

[0071] Furthermore, the acidic substances in the second acidic delivery area and the alkaline substances in the second alkaline delivery area can also determine the reminder thresholds in the above manner to avoid affecting the overall washing effect when the pH value of the rinse water cannot be adjusted.

[0072] The present application also provides a clothing processing device that adopts the above-mentioned clothing processing device control method. The water inlet pipeline 6 of the clothing processing device includes a first sensor 1 for detecting the pH value of an external water source, a filter 2 for filtering large particles of impurities, and a microbial sensor 3 for detecting the concentration of microorganisms in the external water source, which are arranged in sequence. When the water flows into the inner drum 4 through the first sensor 1, the filter 2 and the microbial sensor 3 in sequence, the clothing processing device determines whether the pH value of the current washing water is within the set range based on the feedback information of the second sensor 5. If not, the first alkaline delivery area or the first acidic delivery area continues to work; if so, it is further determined whether the current delivery amount of the clothing treatment agent is greater than or equal to the preset delivery amount determined according to the weight of the clothes. If so, stop delivering the clothing treatment agent; if not, switch to the neutral delivery area for delivery.

[0073] When water flows into the inner drum 4 during the rinsing stage, the clothing processing device determines whether the pH value of the current rinsing water is within the set range based on the feedback information of the second sensor 5. If not, the clothing processing device controls the second alkaline delivery area or the second acidic delivery area to work. If so, executes the preset program.

[0074] Furthermore, a weight sensor for detecting the weight of clothes is also provided in the inner drum 4 of the present invention, and the clothes treating device determines the amount of water inflow from the external water source and the amount of clothes treating agent added through feedback information from the weight sensor.

[0075] The clothing processing device of the present invention is also provided with a third sensor for detecting ozone concentration. When and only when the washing process is completed and the ozone concentration drops to a safe concentration, the clothing processing device reminds the user to pick up the clothes; or the clothing processing device of the present invention is also provided with an olfactory sensor for detecting disinfectant concentration. When the disinfectant concentration is less than or equal to the set concentration, the clothing processing device executes a preset program.

[0076] In another embodiment of the present invention, the first sensor 1 for detecting the pH value of the external water source provided on the water inlet pipe 6 can be omitted. In this case, the clothing processing device can obtain the current location information and obtain the pH value of the external water source at the location through the location information network.

[0077] 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. The implementation scheme in the above embodiment can also be further combined or replaced. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the solution of the present invention.
