The embodiment, such that the first and second features may not be in direct contact.

In the description of the present invention, it should be noted that, unless otherwise specified and limited, the terms "installation", "connected", and "connected" are to be understood broadly, and may be, for example, mechanically or electrically connected, or The internal communication of the components may be directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms may be understood according to specific situations.

A drum washing machine and a drum washing machine control method according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

1 is a block schematic view of a drum washing machine in accordance with an embodiment of the present invention. As shown in Fig. 1, the drum washing machine includes: a body 10, a door 20, a door lock assembly 30, a midway opening button 40, and a controller 50.

The door lock assembly 30 is used to control the lock between the door 20 and the body 10. The middle door open button 40 is used to receive a midway opening command input by the user. The controller 50 is connected to the midway opening button 40 and the door lock assembly 30. The controller 50 determines whether the drum washing machine satisfies the preset door opening condition after receiving the middle door opening command. If so, the controller 50 controls the door lock assembly 30 by The lock between the door 20 and the body 10 is released.

According to an embodiment of the present invention, the preset opening condition includes the following conditions: (1) The temperature inside the drum of the drum washing machine is lower than the preset temperature;

(2) The water level in the drum is lower than the preset water level;

(3) The drum rotation speed of the drum washing machine is less than the preset rotation speed;

(4) The drain pump of the drum washing machine is turned off; and

(5) The drum washing machine has no trouble.

That is to say, before controlling the door of the drum washing machine to be unlocked, it is critical to determine whether the drum washing machine satisfies the preset door opening condition, and only the temperature in the drum of the drum washing machine is lower than a preset temperature, for example, 60 degrees, and the water level in the drum is lower than The controller 50 controls the door lock assembly 30 when the preset water level is lower than the door seal water level, the drum rotation speed of the drum washing machine is less than the preset rotation speed, for example, 45 r/m, the drain pump of the drum washing machine is in the closed state, and the drum washing machine is detected to be faultless. In order to unlock the door of the drum washing machine, the user can open the door and add clothes. Therefore, in the embodiment of the present invention, the opening of the drum washing machine in the middle is carried out under the premise of ensuring the safety of the user.

According to an embodiment of the present invention, the drum washing machine described above further includes a control panel (not shown), and the middle opening button 40 is disposed on the control panel.

Preferably, according to an embodiment of the present invention, as shown in FIG. 2, the drum washing machine further includes a prompter 60. The prompter 60 is connected to the controller 50, and the prompter 60 determines at the controller 50 that the drum washing machine meets the preset opening door. The condition emits the first prompt tone, that is, the safe opening of the door.

Moreover, when the controller 50 determines that the drum washing machine does not satisfy any of the preset door opening conditions, the prompter 60 emits a second prompt sound, that is, the door open invalid sound, and does not respond to the user input midway opening command, and the user cannot open the door.

According to the drum washing machine of the embodiment of the present invention, after receiving the midway opening command input by the user through the midway opening button input, the controller determines whether the drum washing machine satisfies the preset door opening condition, and if satisfied, the controller controls the door lock assembly to release the door and The locking between the bodies makes it easy for the user to open the door to add clothes, which is convenient for the user. Moreover, it is not necessary to wait until the next washing, which not only saves time, but also saves water and electricity, and saves energy and environmental protection.

Specifically, according to an embodiment of the present invention, as shown in FIG. 4, the above control method of the drum washing machine includes the following steps:

5401. Determine whether a midway opening command input by the user is received. If yes, go to step S402; if no, go back.

At 5402, it is judged whether the drum rotation speed of the drum washing machine is less than a preset rotation speed, for example, 45 r/m. If yes, go to step S403; if no, go to step S408.

5403. Determine whether the temperature in the drum of the drum washing machine is lower than a preset temperature, for example, 60 degrees. If yes, step S404 is performed; if no, step S408 is performed.

5404. Determine whether the water level in the drum is lower than a preset water level such as a door seal water level. If yes, go to step S405; if no, go to step S408.

5405. Determine whether the drain pump of the drum washing machine is in a closed state. If yes, go to step S406; if no, go to step S408.

5406, determining whether the drum washing machine has a fault. If yes, go to step S408; if no, go to step S407.

5407, controlling the door of the drum washing machine to unlock, opening the door of the drum washing machine. Among them, in control After the door of the drum washing machine is unlocked, the first prompt tone is sent to the user, that is, the door opening sound is safely opened, prompting the user to open the door of the washing machine. That is to say, when the drum washing machine satisfies the preset door opening condition, the first prompt sound is sent to the user.

S408, issuing an invalid sound in the middle of opening the door, and does not respond to the user's input midway opening instruction. That is to say, when the drum washing machine does not satisfy any of the above-mentioned preset opening conditions, the user is issued the first "nothing"
