The door opening tilt angle in this embodiment is obtained through multiple groups of experimental data tests, such as Figure 2 As shown, the present application discloses an automatic dehydration control method for improving the dehydration performance of an industrial washing machine. The automatic dehydration control method in this embodiment is used to control the industrial washing machine to perform a dual-axis dehydration process. The automatic dehydration control method in this embodiment specifically includes the following steps:

[0054] S10: Obtain the weight of the clothes in the inner drum of the industrial washing machine when washing is completed and the weight distribution of the clothes in the inner drum, and analyze the optimal dehydration power of the current washing clothes according to the weight of the clothes in the inner drum.

[0055] Specifically, the industrial washing machine in this embodiment is a horizontal type. When the industrial washing machine completes washing, the washing program is switched to the dehydration program. During the program switching process, the total weight of the clothes in the current inner drum and the weight distribution of the clothes in the inner drum are obtained. For example, if the weight of the clothes on the left side is greater than the weight of the clothes on the right side, or the weight of the clothes on the left and right sides is close to equal, the optimal dehydration power of the current washing clothes is expressed by formula (1). Formula (1) is as follows:

[0056]

[0057] Among them, P 脱 Indicates the optimal dehydration power for the current washing clothes, G 衣 represents the current weight of the inner drum clothes, S represents the torque between the motor and the inner drum, ΔG 单 represents the weight of a single dehydration when the inner drum rotates one circle, η represents the motor operating speed corresponding to the weight of a single dehydration of the inner drum, U and I represent the rated dehydration voltage and rated dehydration current of the industrial washing machine within the rated weight range, respectively, 额 Indicates the rated dehydration weight of an industrial washing machine.

[0058] S20: adjusting the single-axis dehydration power of the double-side transmission shafts of the industrial washing machine according to the weight distribution of the clothes and the optimal dehydration power, so as to obtain the double-axis comprehensive dehydration power corresponding to the corresponding weight distribution of the clothes on each side of the transmission shaft.

[0059] Specifically, Figure 3 As shown, step S20 includes:

[0060] S201: Obtain the single-side clothing weight of the corresponding side of each transmission shaft according to the clothing weight distribution, and calculate the corresponding single-axis dehydration power according to the single-side clothing weight and the transmission shaft torque of the corresponding transmission shaft.

[0061] Specifically, the single-side clothing weight corresponding to the double-sided drive shafts of the inner drum is obtained according to the distribution of clothing weight, which in this embodiment mainly refers to the supporting weight detected by the single-sided drive shaft, and based on the single-side clothing weight and the drive shaft torque of the corresponding side drive shaft, which in this embodiment refers to the axial length between the connection position of the single-sided drive shaft and the inner drum, the product of the gravity corresponding to the single-side clothing weight and the torque of the corresponding side drive shaft is taken as the corresponding single-axis dehydration power.

[0062] S202: Combined with the optimal dehydration power, the dual-axis comprehensive dehydration power corresponding to the weight distribution of the clothes on each side of the transmission shaft is expressed by formula (2), and formula (2) is as follows:

[0063]

[0064] Among them, P 综 Indicates the comprehensive dehydration power of the dual-axis of the industrial washing machine, P 单1 , P 单2 They represent the single-axis dehydration power corresponding to each side motor of the industrial washing machine. The dehydration difference coefficient is used to indicate the dehydration difference of the drive shafts on both sides of the inner drum caused by the uneven distribution of clothes in the inner drum.

[0065] S30: During the dehydration process according to the dual-axis comprehensive dehydration power, the swinging pressure of the clothes in the drum on the inner drum wall is obtained, and whether the clothes in the inner drum are swung evenly is analyzed according to the swinging pressure to obtain dehydration vibration data.

[0066] Specifically, Figure 4 As shown, step S30 includes:

[0068] Specifically, in the process of dehydrating the industrial washing machine according to the dual-axis comprehensive dehydration power control, the swing deviation angle between the central axis of the inner drum of the washing machine and the torque of the transmission shaft is obtained, and the swing pressure of the clothes on the inner drum wall is calculated according to the swing deviation angle. The swing pressure in this embodiment is the sum of the cosine value of the weight of the clothes and the dehydration power corresponding to the current speed of the motor.

[0069] S302: Analyze whether the inner drum laundry is evenly swung in the current dehydration state according to the swing pressure, and obtain the dehydration vibration amplitude and dehydration vibration frequency of the washing machine under uneven distribution to obtain dehydration vibration data of the current dehydration state.

[0070] Specifically, whether the swinging distribution of the clothes in the inner drum is balanced in the current dehydration state is analyzed according to the swinging pressure. When the swinging pressure of the drive shaft on one side of the washing machine is uneven with the swinging pressure of the drive shaft on the other side within the error range, it is judged that the current distribution of the clothes in the inner drum is uneven, and the dehydration vibration frequency and dehydration vibration amplitude of the washing machine under the uneven distribution are obtained. The dehydration vibration frequency is the comprehensive vibration effect caused by the simultaneous vibration of two axes, and the dehydration vibration amplitude is the amplitude of the current clothes in the drum to bring the inner drum away from the preset working position of the inner drum, thereby obtaining the dehydration vibration data of the current dehydration state.

[0071] S40: adjusting the optimal airbag damping value of the industrial washing machine according to the dehydration vibration data, and adjusting the current airbag damping value to the optimal airbag damping value in advance at the next unbalanced vibration according to the dehydration rotation cycle of the industrial washing machine.

[0073] S401: Analyze the vibration damping force required for the current dehydration vibration according to the dehydration vibration data, and adjust the optimal airbag damping value of the industrial washing machine according to the analysis result.

[0074] Specifically, the vibration damping force required for the current dehydration vibration is analyzed according to the dehydration vibration data. The vibration damping force is the reverse value of the work done by the current dehydration vibration amplitude. The optimal airbag damping value of the industrial washing machine is adjusted according to the analysis result of the vibration damping force. The optimal airbag damping value corresponds to the reverse value of the work done by the maximum vibration amplitude.

[0075] S402: Obtaining the dehydration rotation cycle of the industrial washing machine in the current dehydration state, and when the dehydration vibration cycle reaches the next unbalanced vibration, pre-adjusting the current airbag damping value of the airbag damper at the corresponding position to the optimal airbag damping value.

[0076] Specifically, the dehydration rotation cycle of the industrial washing machine in the current dehydration state is obtained, such as the adjacent time when the clothes are swung to reach the maximum vibration deviation amplitude. When the dehydration vibration cycle reaches the next unbalanced vibration, that is, when the maximum vibration deviation is reached, the current airbag damping value of the airbag damper at the corresponding position of the inner drum is pre-adjusted to the optimal airbag damping value.
