Problems solved by technology

Generally, the opening or closing of the machine cover is realized by the user's manual operation. Due to the gravity of the machine cover itself and the impact and collision with the control seat when the machine cover is opened / closed manually, after a long time, it is easy to cause the machine Worn or detached cover fails
In addition, as the capacity of the washing machine increases, the machine cover becomes heavier and heavier. At the same time, in order to pursue aesthetics, the material of the machine cover of some models has changed from plastic to glass with a higher density. The lid is more laborious, and it also makes the impact collision more obvious, and the noise generated when the lid is opened / closed is also more obvious

Embodiment 1

[0041] Basic structure reference of top load washing machine figure 1 ,No longer.

[0042] The rear side of the machine cover 4 is connected with the part behind the clothing insertion port 20 on the control seat 2 through the rotating shaft 22, and the part located at the rear of the clothing insertion port 20 on the control seat 2 is provided with a positioning groove 202 for positioning the motor 3, as figure 2 shown. The positioning groove 202 is located in the middle of the rear side of the clothing delivery port 20. The motor 3 has dual output shafts and has bidirectional output capability. The two sides of the motor 3 are respectively provided with rotating shafts 22, so that the output torque of the motor 3 can be relatively stable. The large glass cover 4 can ensure smooth opening / closing. The cross section of the positioning groove 202 matches the cross section of the motor 3 housing. In this embodiment, the housing of the motor 3 is specially selected as a square...

Embodiment 2

[0052] Such as Figure 7 As shown, this embodiment provides a control method for a washing machine with automatic cover opening / closing. The structure of the washing machine has been disclosed in Embodiment 1. You can refer to Embodiment 1. The specific steps of the control method are as follows:

[0053] a) The user starts the machine, and proceeds to step b) after the program is initialized;

[0054] b) The control unit controls the unlocking of the cover lock, the motor executes the command to open the cover, and at the same time, the obstacle detection module detects whether there is an obstacle to opening the cover, if so, proceed to step c), if not, proceed to step d);

[0055] c) The motor suspends the execution of the command to open the cover, and the control unit sends an alarm signal to make the alarm device alarm the user, prompting the user to remove the obstacle. After a certain period of time, the control unit detects whether there is an obstacle to open the cov...

Embodiment 3

[0064] Such as Figure 8 As shown, this embodiment provides a control method for a washing machine with automatic cover opening / closing. The structure of the washing machine has been disclosed in Embodiment 1. You can refer to Embodiment 1. The steps of the control method are based on Embodiment 2 , made some changes to step i) and added follow-up steps. After the washing program is finished, the command to open the machine cover is executed directly, and finally the user is reminded that the washing is completed, so steps a) to h) are omitted, and directly start from step i) ,details as follows:

[0065] i) The washing machine starts to execute the laundry program. In the laundry program, the control unit detects whether the command to open the machine cover is received. If so, the laundry program is suspended, and step b) is performed. If not, the laundry program is continued until the laundry program ends, and the control unit The unit controls the unlocking of the cover l...

Abstract

The invention discloses a washing machine with an automatic opening / closing machine cover, belongs to a household electrical appliance, and solves the problem existing in the prior art that the machine cover cannot be automatically opened and closed. The washing machine mainly comprises a casing and a control seat arranged on the top of the casing, a control unit is arranged in the control seat, the control seat is provided with an operation panel, the control seat is provided with a clothes putting opening, the control seat is connected with a machine cover through a rotating shaft, the control seat is provided with a motor which drives the rotating shaft to rotate around the axial direction of the rotating shaft, the motor is electrically connected with the control unit, the rotating shaft is provided with an angle transducer which monitors the rotation angle of the rotating shaft, the angle transducer is electrically connected with the control unit, and the control unit controls the output torque of the motor in dependence on angle signals fed back by the angle transducer. Furthermore, the invention also provides a control method of the above washing machine. The washing machine with the automatic opening / closing machine cover is mainly used for washing clothes.

Description

technical field [0001] The invention relates to household appliances, in particular to a washing machine with automatic opening / closing of a machine cover and a control method thereof. Background technique [0002] The machine cover of the pulsator washing machine is generally rotatably connected on the control seat, and the control seat has a clothes insertion port. Generally, when the washing machine is not in use, the machine cover covers the clothes inlet and is in a closed state to prevent hair, flying insects, and sundries from falling into the bucket. Also, during the execution of the washing program, the machine cover is also in a closed state. When the user puts clothes into the tub, the machine cover needs to be opened first, and when the user needs to take out the clothes after the washing program is finished, the machine cover also needs to be opened. Generally, the opening or closing of the machine cover is realized by the user's manual operation. Due to the gr...
