Abstract
A drum-type washer features that in its casing there are a washing unit, a buffer unit under the washing unit for supporting it, and a vibration damping unit consisting of spring, front track and rear track for decreasing the back-and-forth vibration at low speed.
Description
Technical field
The invention relates to the technology of roller washing machine aspect, particularly when beginning to wash and before stopping, the porpoise that is produced when preventing low speed rotation improves reliability of products; By preventing the excessive porpoise and the collision of casing, dwindle the architecture advances of the roller washing machine aspect of casing size simultaneously.
Background technology
Washing machine is the device that utilizes the mechanical force washing clothes.Roughly be divided into drum-type and 3 big classes such as stirring-type and vortex according to mode of washing.
Stirring-type: be the mode that the mixer of the wing shape of center perk in a kind of sink washs by left rotation and right rotation.Though washing force is good, there are powerful washing machine noise and vibration and washings impaired, be the mode that is suitable for leviathan.
Vortex: being nineteen sixty in a kind of laundry mode of Japan's exploitation, is the mode that current that the agitator rotation by circular plate type produces wash.The product at initial stage causes clothing to twist strength and be badly damaged because the diameter of agitator is little and rotary speed is fast.Along with agitator becomes maximization, the shortening of left and right sides half way around time, product has obtained good improvement and washability is also very strong after the eighties.
Drum-type: be that cylinder inside mainly is made up of a plurality of protuberances, put into water, washing agent and washings, utilize the trunnion axis low speed rotation, washings is impacted up and down by protuberance wash in above-mentioned cylinder inside.This mode has not damage of washings, the advantage that water consumption is few, but because a little less than the washing force, need utilize heater that water is heated, power consumption again, wash time is long again, and shortcomings such as noise is big are arranged, be mainly used in the many Europe of detergent dissolution degree difference hard water and be extensive use of.
Though roller washing machine has above-mentioned variety of problems, do not hinder washings, played bactericidal action by high-temperature wash, can also directly dry after the dehydration.Actual proof, this demand becomes ascendant trend.
Below with reference to Fig. 1 the roller washing machine of prior art is elaborated.The roller washing machine of prior art has following structure: casing 17 is hollow regular hexahedron shapes; Outer bucket 11 is positioned at the inside of above-mentioned casing 17, is used to adorn water; Cylinder 12 is inserted in the above-mentioned urceolus 11, can hold washings; Washing portion is fixedly connected on the back of above-mentioned urceolus 11, by drive motors (drawing is not showed) swing roller 12; One end of air throttle 13 is fixedly connected on the bottom surface of above-mentioned casing 17, and the other end is fixedly connected on above-mentioned washing portion, and supports above-mentioned washing portion; One end of spring 14 be fixedly connected on above-mentioned casing 17 above, the other end is fixedly connected on above-mentioned washing portion, and supports washing portion, plays damping effect.The outer upper of above-mentioned outer bucket 11 have can fixedly connected above-mentioned spring 14 ring, the outer lower portion of above-mentioned outer bucket 11 have can fixedly connected above-mentioned air throttle 13 ring.Above-mentioned outer bucket 11 fronts are equipped with gravitational equilibrium piece 15, and the front end of side is equipped with gravitational equilibrium piece 16.In addition, the heater that improves coolant-temperature gage is arranged on the privileged site of the outside.Above-mentioned cylinder 12 is made up of the impeller with a certain size of dewatering hole that can flow into water and lifting washings.
Above-mentioned drive motors (drawing is not showed) is positioned at above-mentioned outer barrel 11 back, and drive motors rotates 12 cleaning functions of above-mentioned cylinder.
Above-mentioned air throttle 13 is buffer units, between the bottom surface of above-mentioned casing 17 and above-mentioned washing portion, supports above-mentioned washing portion, and the impact that produces during simultaneously to carrying or during dehydration plays cushioning effect.
Above-mentioned spring 14 is on above-mentioned casing 17 and between the above-mentioned washing portion, supports above-mentioned washing portion, and the vibration that produces during simultaneously to the rotation of above-mentioned washing portion plays damping effect.General use a plurality of springs, major part mainly by about 2 central spring and secondary spring form.Above-mentioned central spring is positioned on the vertical extended line of above-mentioned washing portion center of gravity, and above-mentioned secondary spring is positioned at the front and back end of above-mentioned casing 17, and above-mentioned secondary spring not only all plays vibration damping to the side-to-side vibrations of above-mentioned washing portion and to porpoise.
Roller washing machine with prior art of said structure uses a plurality of springs to cut down side-to-side vibrations and porpoise to sink, but for reducing the porpoise DeGrain that produces when washing portion drives the low speed rotation of initial stage and terminal stage.
With reference to Fig. 2, the washing portion 100 that forms by outer bucket 11 and cylinder 12 and drive motors 18 during low speed rotation as can be seen, although the damping effect of spring 14 is arranged, still the front-back of swing and casing 17 collides.Such collision and noise can damage internal part and make roller washing machine itself break away from the original position that is provided with.To this, the measure of taking that prevents is the inner space that enlarges casing, but supports or opposes with trend toward miniaturization.
Summary of the invention
In order to address the above problem, the purpose of this invention is to provide a kind of porpoise of the washing portion that produces when cutting down low speed rotation effectively, improve reliability of products, prevent to impact and reduce noise.
Technical solution of the present invention provides a kind of tumbling-box washing machine, comprise that in its casing 17 inside washing portion 100, buffer part 13 and vibration damping portion form, buffer part 13 is positioned at the bottom of above-mentioned washing portion and supports washing portion, it is characterized in that vibration damping portion is made up of spring 14, front guide rail 31 and back guide rail 32, front guide rail (31) and back guide rail (32) are positioned at the both sides of spring (14).
Good effect of the present invention is the tumbling-box washing machine with said structure, and the porpoise when utilizing the vibration damping portion that has guide rail to cut down low speed rotation effectively prevents because impact and the noise that porpoise produces successfully waits other program conversions to dehydration.Because Oscillation Amplitude reduces, can carry out miniaturization to the whole size of tumbling-box washing machine and improve.
