Next, based on the aforementioned laundry treatment equipment, the deodorization control method of the laundry treatment equipment according to the embodiment of the present application will be introduced.

As shown in Figure 1, the deodorization control method of the laundry treatment equipment in the embodiment of the present application includes:

Step 101, determine the deodorization type of the laundry to be treated.

Here, the laundry treating apparatus may determine a deodorization type based on an instruction input by a user. For example, the user may input an instruction to select a deodorization type through buttons on the laundry treatment device, a touch screen, or a remote controller wirelessly connected to the laundry treatment device, and the laundry treatment device determines the deodorization type based on the received instruction.

Exemplarily, a display screen may be provided on the top of the laundry processing device, and the user may switch the current deodorization type displayed on the display screen based on a key, and select to confirm the deodorization type of the laundry to be treated.

Exemplarily, in the embodiment of the present application, the types of deodorization are divided based on the different odors of the clothes, as shown in Table 1 below:

Table 1 Classification of deodorization types

It can be understood that for the smell of smoke, it mainly involves hydrocarbons and hydrocarbon oxides, sulfides and nitrides, and is classified into the first type; It mainly involves volatile and water-soluble odor molecules such as isovaleric acid, methyl mercaptan, acetic acid, ammonia water, and sulfide, which are classified into the second type; for hot pot odor, it mainly involves volatile molecules such as oil and spices. However, odor molecules that are not easily soluble in water are classified into the third type.

Step 102, based on the type of deodorization, control the laundry treatment equipment to run a corresponding deodorization control program; wherein, the deodorization control program of each deodorization type is different based on the control strategy of the condensate water supply valve and/or the steam generator.

In the embodiment of the present application, because the deodorization control procedures of each deodorization type are different based on the control strategy of the condensate water supply valve and/or the steam generator. In this way, the control strategy of the condensate water supply valve and/or the steam generator can be adjusted for different types of deodorization, so that the deodorization effects of different odors on the clothes can be improved in a targeted manner to meet people's different needs for deodorization.

Exemplarily, for each type of deodorization, different deodorization control programs may be pre-configured in the laundry treatment device. In the embodiment of the present application, for the above-mentioned first type, second type, and third type, considering the differences in the volatility and solubility of odor molecules, each deodorization control program can be based on the opening timing of the condensate water supply valve and/or The steam generator is distinguished by the opening time corresponding to a single operation, so that it can meet the deodorization needs of different types of odors based on steam deodorization, and can accurately control the temperature and humidity in the barrel to achieve customized care for clothes.

Exemplarily, based on the type of deodorization, the laundry treatment equipment is controlled to run a corresponding deodorization control program, including:

Control the laundry treatment equipment to alternately operate in the first stage of enhancing the volatilization of clothes odor and the second stage of deodorization based on steam;

Control the laundry treatment equipment to operate in the third stage of drying the laundry.

Among them, in the first stage and the third stage, the steam generator is turned off; in the second stage, the steam generator is turned on; All heating devices are turned on, and the drum of the laundry treatment equipment rotates based on the set strategy.

It can be understood that in the above first stage, the barrel rotates based on the set strategy, and the clothes in the barrel can be thrown repeatedly, and under the action of the fan and the heating device, the airflow in the barrel can flow and be heated, which is beneficial to strengthen the clothes. The smell is volatile.

It can be understood that in the above second stage, since the steam generator is turned on, combined with the action of the fan and the heating device, the steam deodorization can be performed based on the steam generated by the steam generator. The steam deodorization refers to the use of steam to dissolve odors. Odor molecules.

It can be understood that the above-mentioned third stage is located after alternately running the above-mentioned first stage and the second stage multiple times. Considering that the clothes in the barrel may be wetted by steam and to avoid the steam rushing out when the door is subsequently opened, it can be closed The steam generator, combined with the action of the fan and the heating device, can dry the clothes in the barrel.

It is understandable that for the smoke smell, the hydrocarbons involved and the particulate odor molecules such as hydrocarbon oxides, sulfides, and nitrides are easily peeled off from the surface of the clothes, and the condensed water supply valve can be opened in time to rinse with condensed water Particulate odor molecules, which are dissolved in condensed water and discharged.

Exemplarily, after the condensate water supply valve is opened, water can be supplied based on the set work cycle, for example, with a period of two minutes on and one minute off, and cycle work. The embodiment of the present application does not specify the work cycle of the condensate water supply valve. limited.

In some embodiments, if the deodorizing type is the second type for at least one of sweat, musty, stinky socks, and snail powder, the method further includes: determining that the temperature in the laundry processing equipment is greater than or equal to the second type. Once the temperature is set, open the condensate supply valve.

Exemplarily, a temperature sensor can be set at the condenser, and based on comparing the temperature value detected by the temperature sensor with the first set temperature, if it is determined that the detected temperature value is greater than or equal to the first set temperature, then the condensed water supply will be turned on valve. It should be noted that the temperature sensor can also be set at other positions, as long as it can characterize the temperature value associated with the airflow in the barrel, the temperature sensor can be an NTC (Negative Temperature Coefficient, negative temperature coefficient) temperature sensor, the embodiment of the present application There is no limit to this.

It can be understood that for odor molecules such as isovaleric acid, methyl mercaptan, acetic acid, ammonia water, sulfide, etc., it is necessary to accelerate their volatilization at a certain temperature, and then use the property of odor molecules to be easily soluble in water to dissolve them in condensation water and drain.

In some embodiments, if the deodorizing type is the third type for hot pot odor, the method further includes: determining that the temperature in the laundry treatment equipment is greater than or equal to the second set temperature, and opening the condensate water supply valve; wherein, the second The set temperature is greater than the first set temperature.

It can be understood that for odor molecules such as grease and spice molecules, they need to be dissolved in water at a certain temperature. In the embodiment of the present application, it is determined that the detected temperature is greater than or equal to the second set temperature, and the condensed water supply valve is opened, which is beneficial. The steam under high temperature dissolves such odor molecules, and is discharged after being condensed in the condenser.

Exemplarily, the value range of the first set temperature is 30-40°C, and the value range of the second set temperature is 35-45°C.

It should be noted that, to control the laundry treatment equipment to alternately run the first stage and the second stage, it may be to run the first stage first and then the second stage, and so on until the set number of cycles is reached; or, to run first Run the first stage after the second stage, and so on, until the set number of cycles is reached, and finally run the second stage once. That is, the second stage needs to be run as the end condition of the aforementioned alternate operation, and the start condition of the alternate operation can be to run the first stage or the second stage. Preferably, the initial condition of the alternate operation is to operate the first stage, which is beneficial to fully volatilize the odor molecules on the clothes before the steam deodorization.

controlling the barrel to rotate at least one rotational speed less than the critical rotational speed for a first set duration;

controlling the barrel to rotate at least one rotation speed greater than or equal to the critical rotation speed for a second set duration;

It can be understood that controlling the barrel to rotate at least one speed less than the critical speed for the first set time can make the clothes in the barrel be beaten and thrown during this process, which is beneficial to the volatilization of odor molecules and the contact between the airflow and the surface of the clothes. It should be noted that, for the first stage, the contact between the airflow and the surface of the clothing can accelerate the volatilization of the odor molecules; for the second stage, the contact of the steam with the surface of the clothing can dissolve the odor molecules in time.

It can be understood that, the barrel is controlled to rotate at least one speed greater than or equal to the critical speed for a second set duration, so that the clothes in the barrel can be rotated against the inner wall of the barrel during this process, so that the clothes in the barrel can be cleaned. Shaping is beneficial to eliminate the wrinkles generated in the process of the aforementioned speed less than the critical speed.

In some embodiments, in the third stage, the rotation of the tub of the laundry treatment device based on a set strategy includes: controlling the tub to rotate at least one rotation speed less than a critical rotation speed for a third set duration.

It can be understood that, in the third stage, controlling the barrel to rotate at a speed less than the critical speed can make the hot air flow fully exchange heat with the clothes in the barrel, thereby improving the drying efficiency.

In some embodiments, the method further includes: in the second stage, determining the on-time of the steam generator based on the type of deodorization; wherein, the on-time of the third type is greater than that of the second type or the first type.

Considering that the third type of odor molecules are difficult to dissolve in water at normal temperature, by prolonging the opening time of the steam generator in the second stage, the temperature in the barrel can be raised based on steam, and the volatility of the odor molecules can be enhanced, and the odor molecules can also It can be fully dissolved by high-temperature steam, and thus carried to the condenser by the steam, condensed by condensed water and then discharged.

In some embodiments, before controlling the laundry treatment equipment to run the corresponding deodorization control program, the method further includes: controlling the laundry treatment equipment to operate in the fourth stage; the fourth stage is used to preheat the steam generator and control the tub Shake out the laundry.

Here, considering that the steam generator needs a certain preheating time, the steam generator can be turned on for a fourth set time before running the corresponding deodorization control program. The fourth set duration may be determined based on the working performance of the steam generator, for example, may be determined based on the duration of replenishing water of the steam generator and the heating duration required for preheating. Exemplarily, in the fourth stage, the heating device, the fan and the condensed water supply valve are not turned on, and the barrel rotates at a speed lower than the critical speed, thereby shaking off the clothes.

In some embodiments, after the third stage of drying the clothes is controlled, the method further includes: controlling the clothes treating device to operate in a fifth stage; the fifth stage is used for cooling the clothes in the tub.

Exemplarily, in the fifth stage, the heating pipes and steam generators of the laundry treatment equipment are controlled to be closed, the fan and the condensed water supply valve are controlled to be opened, and the rotation of the barrel is controlled, so that the circulation of the air flow and the condensation of the condensed water are used to reduce the barrel temperature.

It can be understood that the laundry treatment equipment can also be configured with a default deodorization control program, that is, when the user does not select the deodorization type or the clothes to be treated are difficult to be classified into the aforementioned deodorization types, the default deodorization control program can be run. The deodorization control program can be any of the aforementioned various deodorization control programs, which is not limited in this embodiment of the present application.

The present application will be further described in detail below in conjunction with application examples.

Fig. 2 is a schematic flowchart of the aforementioned first type of deodorization control method in an application example. As shown in Figure 2, the deodorization control method includes:

Step 201, control the steam generator to turn on for 2.5 minutes, and control the barrel to rotate.

It can be understood that step 201 corresponds to the aforementioned fourth stage. Here, the fan, the heating device and the condensed water supply valve are not turned on, and the steam generator is controlled to be turned on for 2.5 minutes to realize the preheating of the steam generator, so that the steam generator can generate steam immediately afterwards. Exemplarily, the barrel can be controlled to rotate for 10 seconds, pause for 5 seconds, and rotate forward and reverse alternately at 50 rpm (revolutions per minute). In this way, during the preheating stage of the steam generator, the clothes in the tub can be shaken off, making preparations for the subsequent operation of the deodorization control program. In addition, the condensed water is not turned on at this time, the clothes in the bucket are only in a state of shaking off, and the odor molecules have not begun to diffuse and volatilize.

In step 202, the steam generator is turned off, the fan, the heating device and the condensed water supply valve are all turned on, and the barrel is controlled to rotate based on the set strategy.

It can be understood that step 202 corresponds to the aforementioned first stage. In the first stage, the steam generator is turned off, the fan, the heating device and the condensed water supply valve are all turned on, and the barrel is controlled to rotate based on the set strategy. Exemplarily, controlling the rotation of the bucket based on the set strategy includes: first controlling the rotation of the bucket for 25 seconds, pausing for 3 seconds, and alternating forward and reverse at a speed of 50 rpm for 56 seconds; then controlling the rotation of the bucket for 25 seconds, Pause the beat for 5 seconds, rotate forward and reverse alternately for 112 seconds at a speed of 60 rpm; then control the barrel to maintain a speed of 80 rpm for 1 minute.

Here, both 50rpm and 60rpm are rotational speeds less than the critical rotational speed, so that the clothing in the bucket is beaten and thrown during this process, which is beneficial to the volatilization of odor molecules and the contact of the airflow with the surface of the clothing.

Here, 80rpm is a rotational speed greater than the critical rotational speed, which can shape the clothes in the bucket body, and is beneficial to eliminate the wrinkles generated during the aforementioned process of less than the critical rotational speed.

It should be noted that, for smoke smell, the hydrocarbons and hydrocarbon oxides, sulfides, and nitrides involved in particulate odor molecules are easily stripped from the surface of the clothes. In this application example, during the deodorization process, the condensation The water supply valve can use the condensed water to flush the particulate odor molecules, dissolve them in the condensed water and discharge them.

Step 203, control the steam generator to be turned on for 168 seconds, keep the fan, the heating device and the condensed water supply valve all turned on, and control the barrel to rotate based on the set strategy.

It can be understood that step 203 corresponds to the aforementioned second stage. Exemplarily, in the second stage, controlling the rotation of the bucket based on the set strategy includes: first controlling the rotation of the bucket for 25 seconds, pausing for 3 seconds, and alternating forward and reverse at a speed of 50 rpm for 56 seconds; then controlling the bucket Rotate for 25 seconds, pause for 5 seconds, rotate forward and reverse alternately for 112 seconds at a speed of 60 rpm; then control the barrel to maintain a speed of 80 rpm for 1 minute.

Here, the steam generated by the steam generator can further dissolve the odor molecules on the clothing through full contact with the clothes in the barrel, and the steam carrying the odor molecules can be condensed into water at the condenser and then drained away.

Step 204, execute the

above steps

202 and 203 in a loop until the number of loops reaches the set number of times.

Exemplarily, the number of cycles may be 2, which is not limited in this embodiment of the present application.

It can be understood that the cyclical execution of

steps

202 and 203 realizes the switching of the steam generator's repeated startup and shutdown, which can play a role in adjusting the humidity and temperature in the barrel, and can slow down the wetting caused by excessive steam in the barrel Clothing or air leakage caused by excessive internal air pressure.

Step 205, turn off the steam generator, keep the fan, the heating device and the condensed water supply valve open, and control the barrel to rotate based on the set strategy.

It can be understood that step 205 corresponds to the aforementioned third stage. Exemplarily, the third stage, controlling the rotation of the barrel based on the set strategy, includes: first controlling the barrel to rotate for 25 seconds, pausing for 3 seconds, and rotating forward and reverse alternately at 50 rpm for 56 seconds; then controlling the barrel Hold for 112 seconds at 60 rpm.

It is understandable that turning off the steam generator can avoid the phenomenon that the steam wets the clothes and the steam rushes out before opening the door. Both 50rpm and 60rpm are lower than the critical speed, which can make the hot air flow fully exchange heat with the clothes in the barrel, thereby improving the drying efficiency.

Step 206, turn off the heating pipe and the steam generator, keep the fan and the condensed water supply valve open, and control the rotation of the barrel.

It can be understood that step 206 corresponds to the aforementioned fifth stage. Exemplarily, controlling the rotation of the barrel includes: first controlling the barrel to rotate for 12 seconds, pausing for 3 seconds, and rotating at 50 rpm alternately for 56 seconds; then controlling the barrel to rotate for 25 seconds, pausing for 5 seconds Beat, the speed of 80rpm is maintained for 1 minute; run alternately until the cooling end condition is met.

Here, 50rpm is a rotational speed less than the critical rotational speed, and the process corresponding to this rotational speed can cause the clothes to be beaten and scattered, which is beneficial to the circulating airflow to cool the clothes; 80rpm is a rotational speed greater than the critical rotational speed, which can shape the clothes in the bucket body, which is beneficial to eliminate the above-mentioned less than the critical rotational speed wrinkles produced during the process.

Fig. 3 is a schematic flowchart of the above-mentioned second type of deodorization control method in an application example. As shown in Figure 3, the deodorization control method includes:

Step 301, control the steam generator to be turned on for 2.5 minutes, and control the barrel to rotate.

Step 302, turn off the steam generator, turn on both the fan and the heating device, control the barrel to rotate based on the set strategy, determine that the detected temperature is greater than the first set temperature, and turn on the condensed water supply valve. In this embodiment, the second type of odor includes: sweat, stinky socks, snail powder, ammonia, etc. These odors mainly contain volatile and water-soluble odor molecules, which need to be accelerated at a certain temperature. Therefore, for this kind of odor, after the program is started, first use hot air and high-energy steam to raise the temperature of the barrel, and then turn on the condensed water. At this time, the odor molecules can be easily soluble in water, so that they can be dissolved in condensed water and discharged out of the barrel. .

Step 303, control the steam generator to be turned on for 168 seconds, keep the fan, the heating device and the condensed water supply valve all turned on, and control the barrel to rotate based on the set strategy.

Step 304, execute the

above steps

302 and 303 in a loop until the number of loops reaches the set number of times.

Step 305, turn off the steam generator, keep the fan, the heating device and the condensed water supply valve turned on, and control the barrel to rotate based on the set strategy.

Step 306, turn off the heating pipe and the steam generator, keep the fan and the condensed water supply valve open, and control the rotation of the barrel.

The steps 301 to 306 correspond to the above steps 201 to 206, the difference is that in step 302, the condensed water supply valve needs to be opened only after it is determined that the detected temperature is greater than the first set temperature. For the rest, reference may be made to the foregoing description, which will not be repeated here.

Exemplarily, an NTC temperature sensor is set at the condenser, and a detected temperature value is obtained based on the NTC temperature sensor.

It can be understood that for odor molecules such as isovaleric acid, methyl mercaptan, acetic acid, ammonia water, sulfide, etc., it is necessary to accelerate their volatilization at a certain temperature, and then use the property of odor molecules to be easily soluble in water to dissolve them in condensation water and drain. Based on this, in this application example, by controlling the opening timing of the condensed water supply valve, for example, when the detected temperature value is determined to be greater than 35°C, the condensed water supply valve is turned on, so that the odor volatilized after heating in the barrel can be reduced. Molecules dissolve in condensed water and drain.

Fig. 4 is a schematic flow chart of the above-mentioned third type of deodorization control method in an application example. As shown in Figure 4, the deodorization control method includes:

Step 401, control the steam generator to be turned on for 2.5 minutes, and control the barrel to rotate.

Step 402, turn off the steam generator, turn on both the fan and the heating device, control the barrel to rotate based on the set strategy, determine that the detected temperature is greater than the second set temperature, and turn on the condensed water supply valve.

Step 403, controlling the steam generator to be turned on for 228 seconds, keeping the fan, the heating device and the condensed water supply valve all turned on, and controlling the barrel to rotate based on the set strategy.

Step 404, execute the

above steps

402 and 403 in a loop until the number of loops reaches the set number of times.
