As shown in fig. 1 to 6, an embodiment of the present application provides a dishwasher, which includes a machine body 1, a door body 2, and a door closing assembly 3. Wherein, the body 1 has a washing chamber with an opening 11 on one side; the door body 2 is mounted on the body 1 and closes the opening 11, and the door body 2 is rotatably movable with respect to the body 1 about a rotation axis 4 parallel to a lower edge of the opening 11 to open or close the opening 11. The door closing assembly 3 includes an elastic body 31, a steering member 32 and a pull rope 33, wherein one end of the elastic body 31 is connected with the side wall of the machine body 1, the steering member 32 is fixedly arranged on the side wall of the machine body 1, a first end 331 of the pull rope 33 is connected with the door body 2, and a second end 332 bypasses the steering member 32 and is connected with the other end of the elastic body 31.

The working principle of the application is as follows: when the door body 2 is in a closed state, the elastic body 31 and the pull rope 33 are in a slightly tensioned state, and the deformation of the elastic body 31 is minimum, so that the pulling force of the pull rope 33 on the door body 2 is minimum; the body 1 and/or the door 2 can also be provided with a magnetic part, and the door 2 is in a closed state under the action of the pulling force of the pull rope 33 and/or the magnetic force of the magnetic part. When the door body 2 is gradually opened, the door body 2 drives the pull rope 33 to move, so that the elastic body 31 is stretched and deformed to increase, the elastic force generated by the elastic body 31 is increased, and the pulling force F of the pull rope 33 on the door body 2 is gradually increased; at this time, the door body 2 receives two moments in opposite directions: one is a door-closing moment Fa generated by a pulling force F of the pulling rope 33 on the door body 2 with respect to the rotating shaft 4, and the other is a door-opening moment Nb generated by a component force N of the weight G of the door body 2 in a direction perpendicular to the door body 2 with respect to the rotating shaft 4. In the process that the door body 2 is opened from closing to full opening, the elastic force generated by the elastic body 31 is gradually increased, the pulling force F on the pulling rope 33 is gradually increased, the component force N of the weight G of the door body 2 in the direction vertical to the door body 2 is also gradually increased, and the door closing moment Fa and the door opening moment Nb are always kept in a balanced state, so that the door body 2 can hover at any angle in the opening and closing process.

The first end 331 of the pull rope 33 is located above the steering component 32, and at least when the door body 2 does not completely close the opening 11, the straight line RA passing through the first end 331 and part of the pull rope 33 is located on one side of the rotating shaft 4 facing the washing chamber, so as to ensure that at least when the door body 2 does not completely close the opening 11, the pulling force of the pull rope 33 on the door body 2 generates a door closing moment for closing the opening 11 by the door body 2 relative to the rotating shaft 4, so that the door body 2 has a certain damping feeling in the opening and closing range, the door body 2 can stay at any angle in the opening and closing range, and a user can easily open and close the door body 2 in the use process, thereby; meanwhile, the phenomenon that the door body 2 is separated from hands and rapidly sags due to inertia at the moment when a consumer opens the door body 2 is avoided, the damage of hard impact after the door body 2 falls down to the dish washing machine is reduced, and the service life of the dish washing machine is prolonged. In addition, in the moving process of the door body 2, the direction of the pull rope 33 between the steering component 32 and the elastic body 31 is unchanged, so that the installation position of the elastic body 31 can be adjusted according to the whole structure, the overall performance is not influenced, the whole structure layout of the dishwasher is optimized, the installation is compact, the structure is simple, the space is effectively saved, the whole volume of the dishwasher is reduced, the occupied space of a kitchen is reduced, the customer requirements are fully met, and the use experience of a user is improved; and the door closing assembly 3 has simple structure, low manufacturing cost, simple and convenient assembly and good reliability, and is suitable for large-scale popularization and application. Wherein, the elastic body 31 can be a tension spring, and the steering component 32 is a guide wheel or a pulley; the tensile force of the rope 33 against the door body 2 is a resultant force of an elastic force generated by the elastic body 31 and a frictional force between the rope 33 and the steering member 32.

Specifically, when the door body 2 fully opens the opening 11, an included angle RA1O between a straight line OA1 passing through the first end 331 and the rotating shaft 4 and a straight line RA1 passing through the first end 331 and the partial pull rope 33 is 60-120 degrees. In the process that the door body 2 is opened from closing to full opening, as the opening angle of the door body 2 is increased, the component force N of the weight G of the door body 2 in the direction vertical to the door body 2 is gradually increased, the door opening moment Nb is also gradually increased, and the maximum value is reached when the door body 2 is opened fully; in order to balance the door opening torque Nb, the door closing torque Fa needs to be gradually increased and reaches a maximum value when the door body 2 fully opens the opening 11. It can be seen from the formula of the door-closing moment Fa that the door-closing moment Fa can be realized by gradually increasing the pulling force F to the maximum value, gradually increasing the moment arm a to the maximum value, and simultaneously gradually increasing the pulling force F and the moment arm a to the maximum value. In the present application, the elastic body 31 is gradually extended along with the movement of the pulling rope 33, the elastic force generated by the elastic body 31 is gradually increased, the pulling force F on the pulling rope 33 is also gradually increased, and the pulling force F reaches the maximum value F1 when the door body 2 is completely opened; meanwhile, when the door body 2 completely opens the opening 11, the moment arm a1 of the pulling force F1 relative to the rotating shaft 4 is equal to the component OA1sin RA1O of the straight line OA1 in the direction perpendicular to the straight line RA 1; the circle in fig. 5 is a trajectory line of the first end 331 of the rope 33 moving along with the door body 2, and it can be seen that when a straight line RA passing through the first end 331 and part of the rope 33 is tangent to the trajectory circle, the force arm a of the pulling force F of the rope 33 on the door body 2 relative to the rotating shaft 4 is the largest and equal to the radius of the trajectory circle, and at this time ^ RA1O is 90 °; the included angle RA1O is 60-120 degrees, when the door body 2 completely opens the opening 11, the force arm a1 is close to the radius of a track circle, so that when the door closing moment F1a1 is the same, the tension F1 of the pull rope 33 can be correspondingly reduced, the acting force of the pull rope 33 on the steering component 32 is reduced, the steering component 32 is protected, and the service life of the dish-washing machine is prolonged; the pulling force F1 of the pulling rope 33 is reduced, the maximum deformation amount of the elastic body 31 can be reduced, the installation space of the elastic body 31 is effectively saved, the installation is compact, the overall size of the dishwasher is reduced, the occupied space of a kitchen is reduced, the customer requirements are fully met, the user experience is improved, the service life of the elastic body 31 is longer, and the service life of the dishwasher is prolonged; the maximum tensile force required to be provided by the elastic body 31 is reduced, the quality requirement on the elastic body 31 is reduced, and therefore the elastic body 31 which is cheaper can be used, and the cost is saved. Optimally, the included angle RA1O is 90 °, so that when the door body 2 completely opens the opening 11, the force arm a1 is just the radius of the track circle, the maximum elastic deformation of the elastic body 31 is minimum, and the installation space and the manufacturing cost are further saved.

specifically, when the door body 2 completely closes the opening 11, an included angle RA2O between a straight line OA2 passing through the first end 331 and the rotating shaft 4 and a straight line RA2 passing through the first end 331 and the partial pull rope 33 is 0-30 degrees. When the door body 2 completely closes the opening 11, the door opening torque applied to the door body 2 is substantially zero, the door body 2 is in a closed state under the action of the door closing torque F2a2, and when a consumer opens the door body 2, the door closing torque F2a2 needs to be overcome, and the smaller the door closing torque F2a2, the better. At this time, the force arm a2 of the pulling force F2 of the rope 33 on the door body 2 relative to the rotating shaft 4 is equal to the component OA2sin RA2O of the straight line OA2 in the direction perpendicular to the straight line RA 2; the included angle RA2O is 0-30 degrees, and when the door body 2 completely closes the opening 11, the force arm a2 is close to zero, so that the door closing moment F2a2 is greatly reduced, a consumer opens the door body 2 more easily, conveniently and labor-saving, the phenomenon that the consumer applies too much force at the moment of opening the door body 2 is avoided, and good user experience is provided for the consumer; meanwhile, the acting force of the pull rope 33 on the steering component 32 can be reduced, the steering component 32 is protected, and the service life of the dishwasher is prolonged. Optimally, contained angle RA2O is 0, and straight line RA2 passes through pivot 4 promptly, and arm of force a2 is zero, and the moment of closing the door is zero, and the door body 2 is fixed through magnetism with organism 1, makes things convenient for the door body 2 to open initial stage user operation, and is more laborsaving, and user experience is better.
