[0060] Embodiment one

[0061] As shown in Figure 1 and Figure 6 The present application provides a clothes treatment equipment control method, which comprises a clothes treatment drum 2 and a light plasma generating module 3 with an air chamber 32, a fan 33 is arranged in the air chamber 32, and an air outlet 36 of the air chamber 32 is communicated with the clothes treatment drum 2 through an air outlet pipeline 4, characterized in that the control method comprises the following steps:

[0062] Step S1: entering a washing and protecting program;

[0063] Step S2: Control the fan 33 to rotate so as to drive the gas in the air chamber 32 to be blown into the clothing treatment drum 2 through the air outlet duct 4.

[0064] In this embodiment, the speed of the fan 33 is adjusted so that the gas in the air chamber 32 flows into the clothes processing drum 2 through the air outlet pipe 4, thereby preventing the washing water or steam in the clothes processing drum 2 from flowing into the photoplasma generating module 3 through the air outlet pipe 4.

[0065] like Figure 2 As shown, in this embodiment, step S2, which involves controlling the fan 33 to rotate to drive the gas in the air chamber 32 to be blown into the clothing processing drum 2 through the air outlet pipe 4, specifically includes:

[0066] Step S21: Obtain the pressure value inside the clothing processing drum 2 and the pressure value inside the air chamber;

[0067] Step S22: Based on the obtained pressure values ​​inside the clothing processing drum 2 and the air chamber 32, control the fan 33 to run at the corresponding speed to drive the gas in the air chamber 32 to flow to the air outlet 36 of the air chamber 32.

[0068] In this embodiment, the speed of the fan 33 is adjusted by the pressure value inside the clothing processing drum 2 and the pressure value inside the air chamber 32, so as to control the operation of the photoplasma generating module 3 more accurately and efficiently. This avoids the situation where the speed of the fan 33 is too low, resulting in too low airflow through the fan 33, causing the washing water or steam in the clothing processing drum 2 to flow into the photoplasma generating module 3 through the air outlet pipe 4, or the speed of the fan 33 is too high, resulting in too high airflow through the fan 33, which would cause energy waste.

[0069] In this embodiment, step S22, which controls the fan 33 to run at a corresponding speed, specifically includes: determining whether the difference between the pressure value inside the clothing processing drum 2 and the pressure value inside the air chamber 32 is greater than or equal to the maximum preset difference; if so, increasing the speed of the fan 33 so that the air pressure at the outlet 36 of the air chamber 32 is greater than or equal to the air pressure inside the clothing processing drum 2.

[0070] In this embodiment, the maximum preset difference is a positive number. When the pressure difference between the garment processing drum 2 and the air chamber 32 is greater than or equal to the maximum preset difference, there is a risk that the washing water or steam in the garment processing drum 2 will flow back into the photoplasma generating module 3 through the air outlet pipe 4. Therefore, the speed of the fan 33 is increased to effectively prevent the washing water or steam from flowing back into the photoplasma generating module 3.

[0071] In this embodiment, the step S2 of rotating the fan 33 to drive the gas in the gas chamber 32 to blow into the laundry treatment drum 2 through the air outlet pipeline 4 specifically comprises: at least during the rotation of the laundry treatment drum 2, the fan 33 is controlled to rotate, and since the laundry treatment drum 2 rotates, the amount of foam generated by the washing and protecting water in the laundry treatment drum 2 increases or the steam flow in the laundry treatment drum 2 accelerates, and the reverse suction phenomenon is prone to occur.

[0072] As shown in Figure 2 , Figure 5 and Figure 6 In this embodiment, the gas chamber 32 is provided with a light plasma tube 34, and after the fan 33 is operated at a corresponding rotating speed, the following steps are further included.

[0073] Step S3: obtaining the microbial content and / or turbidity value in the laundry treatment drum 2;

[0074] Step S4: determining whether the obtained microbial content and / or turbidity value in the laundry treatment drum 2 is greater than a preset value, and if so, starting the light plasma tube 34 to irradiate the gas chamber 32.

[0075] In this embodiment, whether the light plasma tube 34 is started is determined by judging whether the microbial content and / or turbidity value in the laundry treatment drum 2 is greater than a preset value, so as to ensure the sterilization efficiency of the light plasma generating module 3 and prolong the service life of the light plasma tube 34.

[0076] In this embodiment, under the condition of being powered on, the light plasma tube 34 can emit light plasma and ion clusters, the light plasma tube 34 irradiates the gas inhaled into the gas chamber 32, and the emitted light plasma and ion cluster light decomposes the oxygen and water molecules in the air into hydroxyl, free oxygen atoms, superoxide ions and other oxidizing bodies, thereby forming a sterilization gas. Not only can the laundry treatment drum 2 and the clothes inside be sterilized and treated, but also harmful impurities in the air inside the laundry treatment drum 2 can be decomposed into inert compounds such as carbon dioxide and water, and the peculiar smell of the clothes is quickly and easily removed.

[0077] As shown in Figure 5 and Figure 6 In this embodiment, the light plasma tube 34 is an ultraviolet light tube with UVC ultraviolet and / or UVD ultraviolet wavelength bands.

[0078] The ultraviolet rays can be divided into vacuum ultraviolet rays (super low frequency, UVD), short wave sterilization ultraviolet rays (low frequency, UVC), medium wave erythema effect ultraviolet rays (medium frequency, UVB), and long wave melanin effect ultraviolet rays (high frequency, UVA) according to the wave. Among them, the UVC wave band of the ultraviolet rays has a wavelength of 200-275 nm, and the UVC wave band ultraviolet ray with a wavelength of 253.7 nm has a high sterilization effect; the UVD wave band of the ultraviolet rays has a wavelength of 100-200 nm, and the UVD ultraviolet ray with a wavelength of 185 nm can excite oxygen and water in the air to generate a light plasma group.

[0079] In this embodiment, before the step S4 of starting the light plasma tube 34 to irradiate the gas chamber 32, the following step is further included:

[0080] Step S4': based on the obtained pressure value in the gas chamber 32, the microbial content and / or turbidity value in the clothes treatment cylinder 2, the wavelength of the light plasma tube 34 is determined, and the light plasma tube 34 with the corresponding wavelength is irradiated to the gas chamber 32 for a certain time.

[0081] In this embodiment, based on the pressure value in the gas chamber 32, the microbial content and / or turbidity value in the clothes treatment cylinder 2, the light plasma tube 34 with the corresponding wavelength is started to irradiate the gas in the gas chamber 32 to form a sterilization gas, and then the sterilization gas is introduced into the clothes treatment cylinder 2 through the air outlet pipeline 4, so as to achieve the purpose of completely killing the microorganisms and efficiently removing the odor.

[0082] In this embodiment, after the washing and protection program is completed, the light plasma tube 34 is turned off, and the fan 33 is controlled to stop running.

[0083] Through the above-mentioned clothes treatment equipment control method, the fan 33 rotates to control the gas in the gas chamber 32 to flow to the gas outlet 36 of the gas chamber 32, preventing the washing and protection water or steam in the clothes treatment cylinder 2 from entering the light plasma generation module 3 and causing damage, without the need to set a valve assembly on the gas outlet 36 of the gas chamber 32 and the air outlet pipeline 4, and the operation is simple and easy to implement.

[0084] Embodiment two

[0086] Step S11: entering the washing program;

[0087] Step S21: obtaining the pressure value in the clothes treatment cylinder 2 and the pressure value in the gas chamber 32;

[0088] Step S31: based on the obtained pressure value in the clothes treatment cylinder 2 and the pressure value in the air chamber 32, the fan 33 is controlled to run in the first direction and at the first rotating speed;

[0089] Step S41: obtain the microorganism content and / or turbidity value in the washing water;

[0090] Step S51: determine whether the obtained microorganism content and / or turbidity value in the washing water is greater than a first preset value, if yes, the light plasma tube 34 is started to irradiate the air chamber 32.

[0091] In this embodiment, when the washing machine executes the washing program, the foam containing the care additive is generated in the clothes treatment cylinder 2, and the fan 33 is adjusted to run in the first direction and at the first rotating speed based on the pressure value in the clothes treatment cylinder 2 and the pressure value in the air chamber 32, so as to prevent the foam containing the care additive from flowing back to the air chamber 32 and corroding the light plasma tube 34.

[0092] As shown in Figure 6 In this embodiment, the clothes treatment cylinder 2 and / or the air outlet pipeline 4 are provided with a foam sensor, and the washing program further comprises the following steps after being entered:

[0093] Step S211: detect the foam content in the clothes treatment cylinder 2 and / or the air outlet pipeline 4;

[0094] Step S212: based on the detected foam content in the clothes treatment cylinder 2 and / or the air outlet pipeline 4, determine the pressure value in the clothes treatment cylinder 2 to control the rotating speed of the fan 33.

[0095] In this embodiment, based on the foam content in the clothes treatment cylinder 2 and / or the air outlet pipeline 4, it can be accurately determined whether the pressure value in the clothes treatment cylinder 2 is greater than or equal to the pressure value in the air chamber 32, so as to adjust the rotating speed of the fan 33 and avoid the foam in the clothes treatment cylinder 2 from flowing back to the light plasma generating module 3.

[0096] As shown in Figure 3 In this embodiment, the washing program comprises a water inlet stage, a washing stage and a water drainage stage in sequence; in the washing stage, the microorganism content and / or turbidity value in the washing water is obtained, and whether the light plasma tube 34 is started is determined based on the obtained microorganism content and / or turbidity value in the washing water.

[0097] In the washing stage, the microorganisms and stains in the clothes and the clothes treatment cylinder 2 are uniformly dispersed in the washing water, by detecting the microorganism content and / or turbidity value in the washing water, the light plasma tube 34 corresponding to the wavelength is determined, and the opening time of the light plasma tube 34 is determined, so that the sterilization and deodorization mode is more flexible, and the technical effect of adjusting the sterilization mode according to the microorganism content and / or the dirt degree is realized.

[0103] Step S42: Obtain the microbial content and / or turbidity value in the steam;

[0104] Step S52: Determine whether the microbial content and / or turbidity value in the obtained steam is greater than the second preset value. If so, start the photoplasma tube 34 to irradiate the gas chamber 32.

[0105] When the dryer is running the drying program, the moisture in the clothes is converted into steam under high temperature. The steam contains a certain amount of washing and care additives. Based on the pressure value inside the clothes processing drum 2 and the pressure value inside the air chamber 32, the fan 33 is adjusted to run in the first direction and the second speed to prevent steam from entering the air chamber 32 and corroding the photo-plasma tube 34.

[0106] In this embodiment, based on the microbial content and / or turbidity value in the steam, the wavelength of the photoplasma tube 34 and the corresponding wavelength of the photoplasma tube 34 are determined to irradiate the gas chamber 32, thereby achieving sterilization and deodorization of the inside of the clothing treatment drum 2 and the clothing therein, thoroughly killing microorganisms and efficiently removing odors.
