In some embodiments, the driving member 52e may be an electromagnetic door lock. For example, the driving member 52e includes an electromagnet and a permanent magnet. The electromagnet is fixed to the housing. The permanent magnet is provided with a connecting member for fixing the locking member 51e. The electromagnet is energized to cause the electromagnet and the permanent magnet to generate mutually repulsive forces. Under the action of the magnetic force, the permanent magnet moves toward the hinge 3e, so that the locking member 51e locks the hinge 3e; the current of the electromagnet is reversed. The electromagnet and the permanent magnet are caused to mutually attract each other, and the permanent magnet moves in the direction of the hinge 3e under the action of the magnetic force, so that the lock member 51e is disengaged from the hinge 3e. Alternatively, the driving member 52e may be a motor, and the locking member 51e and the driving member 52e are driven by the rack and pinion.

One side of the back plate is connected to the box body 1e through a hinge 3e, and the two hinges have a certain spacing therebetween. An electromagnetic door lock is arranged between the two hinges. The electromagnetic door lock includes a permanent magnet and two electromagnets. The magnet is located between the two electromagnets, and the permanent magnet is fixed on the casing 1e. Both of the electromagnets are slidably connected to the casing 1e, and a locking unit 5e is connected to one side of the two electromagnets near the hinge 3e. Each of the locking units 5e is connected to a guiding unit 6e, and each of the door covers 2e can lock the door cover 2e and the casing 1e by controlling the current on and off of the corresponding electromagnet and the direction of the current on the electromagnet. Or disengaged, the two door covers 2e can be opened independently, and only one electromagnetic door lock is used, and the structure is compact.

Usually, the washing machine is provided with a switch button, and a lock button can be further provided on the washing machine, and the lock button is used to control the lock unit 5e to unlock the hinge 3e. Or setting a control button in the washing machine, the control button is used to stop the washing machine, and the locking unit 5e unlocks the hinge 3e. The control button can also be used to turn on the washing machine, that is, press the control button once, the washing machine starts to run, and the locking unit 5e The hinge 3e is locked; when the washing machine is in the running state, the control button is pressed again, the washing machine stops running, and the lock unit 5e unlocks the hinge 3e. Of course, for the drum washing machine, when the washing machine has started to operate, when the door cover 2e needs to be opened, it is necessary to satisfy certain conditions (for example, the water level cannot be higher than the set value, the temperature cannot be higher than the temperature limit), so that the door can be closed by the control button. 2e is turned on.

In some embodiments, if the water level of the washing tub in the washing machine is too high, the door cover 2e is opened after draining to the set safe water level; if the water temperature in the washing tub in the washing machine is too high, the washing bucket is first controlled. The cold water is introduced into the water to lower the temperature of the water in the washing tub to a set safe temperature, and then the door cover 2e is opened.

In addition, in order to facilitate opening the door cover, or to limit the opening angle of the door cover.

In another embodiment provided by the present application, as shown in FIGS. 26 to 38, the three-cylinder washing machine further includes a resetting member 4f and an angular limiting structure (not shown), which are reset when the door is unlocked. The restoring force of the piece 4f can drive the door cover 2f to open, and the angular limit structure can define the opening angle of the door cover 2f.

The three-cylinder washing machine provided by some embodiments of the present application, when the door needs to be closed, manually presses the door cover 2f to overcome the restoring force of the resetting member 4f; when the door needs to be opened, the door cover 2f is bounced by the restoring force of the resetting member 4f. Open, making the opening operation saves effort. Moreover, the angle limiting structure can define the opening angle of the door cover 2f, so that the angle of opening the door cover 2f is uniform every time, and no manual adjustment is needed.

In some embodiments, as shown in FIG. 28, the reset member 4f may be a torsion spring disposed on the hinge shaft 21f of the door cover 2f, and the torsion spring includes a first elastic arm 41f and a second elastic arm 42f, first The elastic arm 41f abuts against the door cover 2f, and the second elastic arm 42f abuts against the casing 1f. When the door cover 2f is closed, the first elastic arm 41f and the second elastic arm 42f are close to each other to compress the energy storage. When the lock member 3f is unlocked, the restoring force of the torsion spring drives the first elastic arm 41f to open in a direction away from the second elastic arm 42f. When the door cover 2f is in the closed state, the torsion spring is in a compressed energy storage state, the door cover 2f tends to open, and has an opening force; when the unlocking button is manually operated to unlock the door lock, the door cover 2f is restored in the torsion spring. Under the action, the reverse rotation is started until the door cover 2f is balanced with the torsion spring restoring force, and the door cover 2f is hovered at the position. The stop angle can be adjusted by adjusting the torsion spring force to reach the required angle; if the torsion spring force is large enough, the door cover 2f can be fully opened at a time (ie, the door cover 2f is flipped over 90°). If the door cover 2f is flipped at an angle of less than 90° and needs to continue to open the door cover 2f, the door cover 2f can be manually used to continue to flip the door cover 2f backward until the door cover 2f is flipped over 90°, so that the door cover 2f is under gravity whereabouts.

In an embodiment of the present application, the implementation of the angular limiting structure is as shown in FIG. 29, and the angular limiting structure includes a limiting arm 5f. One end of the limiting arm 5f is fixed on the housing 1f, and the other end extends to the first On the opening trajectory of the elastic arm 41f, when the first elastic arm 41f is opened by the restoring force by the restoring force, the first elastic arm 41f is blocked by the limiting member. Thereby, the opening angle of the door cover 2f can be defined by defining the opening angle of the first elastic arm 41f, so that the opening angle of the door cover 2f is uniform each time, and the structure is simple and easy to implement.

A relief hole is formed in the door cover 2f corresponding to the position of the limit arm 5f. Thereby, interference with the stopper arm 5f can be prevented during the rotation of the door cover 2f, so that the stopper can block the first elastic arm 41f.

In another embodiment of the present application, the corner limiting structure includes a first limiting portion fixed to the door cover 2f and a second limiting portion fixed to the casing 1f, when the door cover 2f is opened to the preset At the angle, the first limiting portion and the second limiting portion are engaged with each other to prevent the door cover 2f from rotating relative to the housing 1f. Thereby, the opening angle of the door cover 2f can be precisely defined by the snap-fit structure, so that the opening angle of the door cover 2f is uniform each time, and the structure can make the opening position of the door cover 2f more precise.

In some embodiments, as shown in FIGS. 30-32, the hinged end of the door cover 2f is provided with a hinge connector 22f, the hinge connector 22f is provided with a sleeve 23f, and the sleeve 23f is sleeved on the hinge of the door cover 2f. On the shaft 21f, the first limiting portion is a card slot 6f disposed on the outer surface of the sleeve 23f, and the second limiting portion is a limiting rod 7f. One end of the limiting rod 7f is fixed to the housing 1f, and the other end is sleeved. The outer surface of the barrel 23f is pressed against, and when the door cover 2f is opened to a predetermined angle, the stopper rod 7f is caught in the card groove 6f. Among them, the limit rod 7f can use a spring wire which can be pressed against the outer surface of the sleeve 23f by a screw. This structure has an accurate limit and a small footprint.

Since the door frame 2f is closed and opened to the hovering point, the frame will continue to be supported by the torsion spring, so that the frame will be abraded or deformed, thereby affecting the appearance of flatness and aesthetics. As shown in Fig. 27, a reinforcing plate 8f is provided at a position where the casing 1f abuts against the second elastic arm 42f, and the second elastic arm 42f abuts against the reinforcing plate 8f. Thereby, the structural strength of the portion is greatly enhanced, and the reinforcing plate 8f can also be used for fixing the damper and the hinge shaft 21f, reducing the number of components to be mounted. The reinforcing plate 8f can be made of a metal material.

In order to prevent the person from opening the cover due to the erroneous operation of the door cover 2f during the operation of the pulsator, there may be problems such as splashing water or even flying out of the clothes. As shown in FIG. 33, the reed switch 11f may be disposed on the casing 1f, and the door cover 2f A magnet 24f is provided thereon. When the distance between the reed switch 11f and the magnet 24f is greater than a predetermined distance, the reed switch 11f can send a signal to the control system of the washing machine to stop the operation of the pulsator. Therefore, when the door cover 2f is opened by an erroneous operation, the control system can stop the pulsator operation in time to ensure the safe operation of the washing machine.

The locking member 3f may be an electromagnetic lock or a mechanical lock. For example, the locking member 3f is a push-type door lock switch. The push-type door lock switch is a mechanical lock. It can be unlocked by simply pressing the push button on the operation panel during operation. The operation is simple, the structure is simple, the cost is low, and the reliability is high.

When opening the cover, the greater the torsion spring force, the faster the opening speed will be. As shown in Fig. 27, exemplified, a damper 9f is added at the hinge shaft 21f of the door cover 2f for slowing the door opening speed. The damper 9f can select a one-way damper or a two-way damper. The one-way damping is suitable when the torsion spring force is relatively small, the door cover 2f has a slow opening speed, the automatic opening angle is small, and the damping effect is only used in the closing process, and the optimal closing is performed. Process speed to enhance the user experience. The two-way damping effect is better, and it can play a buffering effect during the opening and closing process, which can greatly enhance the experience.

In the three-cylinder washing machine provided by the embodiment of the present application, specifically, as shown in FIG. 34 and FIG. 35, a drum washing unit 100f is disposed in the box body 1f, and two pulsator washing units are arranged side by side on the drum washing unit 100f. 200f. Each of the pulsator washing units is separately provided with a door cover 2f.

As shown in FIG. 36, when the moment of the door cover 2f against the hinge rotation point is balanced with the torsion spring buckling moment, that is, when mgL-N=0, the angle θ0 at which the door cover 2f is located is the hovering critical point. For a plurality of door covers 2f, the torsion spring torque and the system resistance are different, and θ0 has a certain range of fluctuations, and it is difficult to ensure complete consistency. Therefore, in order to ensure that the opening angles of the two door covers 2f are uniform, as shown in FIG. 37, the limiting angle θ1 of the angular limiting structure can be set to be smaller than θ0, that is, at the limiting angle θ1, the torsion spring also has a part of the torque reserve. The door cover 2f has a tendency to flip upwards, thereby eliminating the above error and ensuring that the opening angles of the two door covers 2f are uniform.

Further, as shown in FIG. 38, the reinforcing members on the housing 1f corresponding to the two pulsator cans 200f can be formed as a unitary structure, and the shape of the limiting arm 5f on the reinforcing member can be accurately ensured by one press forming. Consistent to ensure that the opening angles of the two door covers 2f are the same.

Some embodiments of the present application also provide a specific structure of the door cover. Referring to FIG. 39, in the three-cylinder washing machine provided by some embodiments of the present application, the door cover corresponding to the pulsator laundry unit includes a door cover body 1g, and the lower surface of the door cover body 1g is connected to the bottom case 2g protruding downward, and the bottom case 2g The edge of the rim is used to seal with the door seal on the washing machine's pulsator washing unit.

When the door cover is closed, the edge of the bottom case 2g can be sealingly fitted with the door seal one week, thereby making the door cover tightly closed when closed, thereby preventing the pulsator washing unit from splashing and overflowing outward.

In order to reduce the weight of the door body 1g, as shown in Fig. 39, optionally, the door cover body 1g is provided as a hollow frame structure, and the cover plate 3g is fixedly attached to the upper surface of the door cover body 1g. Thereby, the weight of the door cover body 1g can be reduced, and the operation of the switch door can be made more labor-saving.

In order to observe the situation inside the washing drum during the washing process. For example, the bottom case 2g and the cover plate 3g are each made of a transparent material, and the cover plate 3g is positioned up and down with the bottom case 2g. Thus, during the washing process, the user can observe the laundry in the pulsator can be observed in real time from the cover 3g.

The fixing manner between the cover plate 3g and the door cover body 1g can be variously selected. For example, the cover plate 3g can be bonded and fixed to the door cover body 1g by double-sided tape, and since the double-sided tape is a flexible member, the cover plate is No rigidity is transmitted between the 3g and the door cover body 1g. For example, in order to improve the overall strength of the door cover, as shown in FIG. 40, a glue groove 4g is formed in the edge of the opening, and the glue groove 4g is provided with a hot-melt cold-setting glue, and the cover plate is passed through the glue in the glue groove 4g. 3g is bonded to the door cover body 1g. After bonding, the pressure-retaining tool is pressed for a certain period of time to correct the problem of door cover warpage and corner flash seam. After the hot melt adhesive is cooled, the door cover body 1g and the cover plate 3g can be The bond is a whole and the strength can be transmitted between the two.
