On the premise of simple structure and easy realization, the drum washing machine of the invention effectively solves the problems of collision noise and displacement generated when the outer drum collides against the box body.
Description
Technical Field
The invention relates to the technical field of washing machines, in particular to a structural improvement of a drum washing machine.
Background
In the dehydration process of the washing machine, if violent oscillation occurs, the phenomenon of cylinder collision can occur, which not only easily causes the displacement of the washing machine, but also generates larger noise. In the prior art, vibration damping and displacement prevention are realized mainly through eccentric detection, balancing eccentricity of a water inlet rotary drum, adjustment of a dehydration rotating speed or a motor rotation-stop ratio, fast passing through a resonance area and the like in the aspect of program control, and vibration damping and displacement prevention are realized mainly through a damper, a balancing ring, a balancing weight, a bottom foot and the like in the aspect of structure. For example, CN201510428024.1 discloses selecting different intermittent dewatering time sequences corresponding to different water amounts, and orderly controlling the rotation speed of the inner barrel to ensure the smooth dewatering of the whole machine. CN201610985781.3 discloses a controller determining an adjustment amount for a variable damper according to vibration monitoring data, and forcibly drawing a washing machine outer drum to suppress the vibration of the washing machine outer drum to ensure that the vibration range of the washing machine outer drum is within a predetermined vibration range. CN201610906752.3 discloses damping vibrations by mounting a gimbal.
The above program control and structural improvement are complex, and under certain severe conditions (for example, clothes are not distributed uniformly), when the eccentricity is large and the vibration is too large, the outer drum still collides with the box body, which causes the problems of collision noise and even displacement, and especially when the washing machine is displaced, the outer drum is likely to collide with or crush other adjacent articles, thereby causing adverse effects on the user experience.
How to reduce collision noise and avoid displacement when the outer cylinder cannot avoid colliding to the box body is the problem to be overcome by the invention.
Disclosure of Invention
The invention aims to provide a drum washing machine which effectively solves the problems of collision noise and displacement generated when an outer drum collides against a box body on the premise of simple structure and easy realization.
In order to achieve the purpose, the invention adopts the following technical scheme to realize the purpose:
a drum washing machine comprises a box body and an outer drum, wherein an avoidance opening is formed in an easy-collision area on the side wall of the box body, and the avoidance opening is used for avoiding collision between the outer drum and the box body.
Furthermore, a flexible body for sealing the avoiding opening is arranged on the side wall.
Further, the flexible body is a sound-proof felt or a wear-resistant rubber plate.
Furthermore, a door body is arranged at the avoiding opening.
Furthermore, the top of the door body is hinged to the side wall, and when the door body is opened to a horizontal position, a supporting rod or a pull rod is arranged between the door body and the side wall.
Furthermore, the bottom of the door body is hinged to the side wall and extends outwards to form supporting legs, and when the door body is opened to a horizontal position, the supporting legs support the door body through abutting against the side wall.
Further, the door body is a rolling door, or the door body is connected to the side wall in a sliding mode.
Furthermore, a reinforcing structure is formed on the side wall around the avoidance opening.
Furthermore, the reinforcing structure comprises a plurality of reinforcing ribs which are arranged at intervals and positioned on the upper side and the lower side of the avoiding opening.
Furthermore, the reinforcing structure comprises long longitudinal beams welded on the left side and the right side of the avoidance port, and cross beams welded on the upper side and the lower side of the avoidance port.
Compared with the prior art, the invention has the advantages and beneficial effects that:
the design idea of the invention is different from the design idea of the prior art, and the prior art carries out program control or structural improvement for reducing the occurrence of barrel collision, so that the scheme is too complex, and the barrel collision phenomenon cannot be thoroughly avoided. The invention is only improved in structure, simple in scheme, and particularly, an easily-collided area can be determined on the side wall of the box body through CAE simulation, actual test experience and the like, and an avoidance port is formed in the easily-collided area. In the dehydration process, when the urceolus is forced to collide to the zone of easily bumping under the drive of inner tube, owing to dodge the setting of mouth, the urceolus will partially stretch out and dodge the mouth and can not bump with the lateral wall of box, and then has avoided the collision noise, because avoid the collision just also stopped the emergence that the box shifted, therefore can promote user experience betterly. Furthermore, after the flexible body is used for closing the avoidance opening, the flexible body not only can play a role in buffering and vibration reduction, but also can play a certain role in sound insulation; when the avoiding opening is provided with the door body, the door body can be used for sealing the avoiding opening in the idle state of the roller washing machine, so that dust, water vapor, winged insects and the like are prevented from entering the interior of the box body through the avoiding opening; due to the arrangement of the avoidance opening, the structural strength of the side wall is reduced to a certain extent, and therefore, a reinforcing structure is further formed around the avoidance opening on the side wall, so that the reliability and the firmness of the whole structure are improved.
