Abstract

The utility model relates to a supporting and moving device which is mainly used on household appliances like a washer. The utility model has the technical proposal that machine feet (6) and rolling wheels (3) are arranged below the base (5) of the supporting and moving device for household appliances. The rolling wheels (3) are arranged on the outer side of the machine feet (6) adjacent to the edge of the base (5). Rotating shafts of the rolling wheels (3) are parallel to the edge of the base (5). The distance between the lowest point of each rolling wheel (3) and the base (5) is smaller than the height of each machine foot (6). The wheel rim of each rolling wheel (3) goes beyond chamfer which is defined by the bottom of each machine foot (6) and the adjacent edge of the base (5). When a box body (2) is inclined by a small angle, the rolling wheels (3) land on floor and play supporting function. The utility model can keep the due stability of a washer, and can optionally and conveniently move the washer according to a user's need.

Description

The household electric appliance supporting moving device

The utility model relates to a kind of supporting moving device of household electric appliance, is particularly useful on washing machine one series products.

Existing household electric appliance, as washing machine supporting on the ground, normally adopt two kinds of schemes: one, adopt under-chassis mechanism, promptly under-chassis directly contacts with ground, good stability but difficult mobile; They are two years old, adopt roller mechanism, roller mechanism directly contacts with ground, conveniently moving, but because roller or the long-term bearing power of universal wheels are poor, surface of contact between wheel and the ground is little in addition, the poor stability that one side electrical equipment is placed, and then vibration and noise are increased, on the other hand, the functional reliability of rolling or universal wheels is poor, thereby roller mechanism is an easily damaged parts.Chinese patent ZL89201884.4, ZL93222116.X and ZL95213476.4 belong to the technological scheme that adopts roller mechanism.The technological scheme different with above-mentioned patent is open by Chinese patent ZL9520626.X, its disclosed technological scheme of utility model patent that is called the cabinet and table feet device with lifting roller ball is to the effect that: support foot, on the parallel platform of the tubular wall outer surface of upper rank of hollow fastening foot, upper and lower supporting hole slot is set respectively and is communicated with the transition slot of upper and lower supporting hole slot, be bearing in the above-mentioned supporting hole slot with the transverse axis on the spin frame, spin is suspended or support hutch table and move.As shown from the above technical solution, ZL95200626.X is a kind of concrete scheme that roller and under-chassis are combined, wherein roller can be in upper and lower two kinds of location statuss respectively, and the conversion of two kinds of location statuss all needs position switching descending operation independently, and is very inconvenient when specifically using.

The purpose of this utility model is to provide a kind of can guarantee the fixedly original supporting stability of under-chassis, the supporting moving device that can conveniently move again.

For achieving the above object, the technical solution adopted in the utility model is: a kind of household electric appliance supporting moving device, be provided with under-chassis and roller below the base, roller is positioned at the under-chassis outside near collet edge, the rotating shaft of roller is parallel with this edge, the minimum point of roller is to the distance of the collet height less than under-chassis, and the wheel rim of roller exceeds the inclined-plane that base edge adjacent thereto limited, above-mentioned under-chassis bottom.

By above technological scheme as can be known, under-chassis is to be fixed on below the base, when machine specifically uses, washing as washing machine, during dehydration, under-chassis play supporting role, place stable when washing machine work is guaranteed in the under-chassis supporting, this all has good effect to reducing vibration and slackening noise, when need are moved shift washer, as long as washing machine is tilted a bit a little, set roller is landed, promptly removable, therefore, the utility model had not only kept the stability that washing machine has but also can arbitrarily move easily according to user's needs.

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment

As Fig. 1,3,4, shown in 5, base (5) is positioned at casing (2) bottom, be provided with under-chassis (6) and roller (3) below the base (5), roller (3) is positioned at the outside of under-chassis (6) near base (5) edge, the rotating shaft of roller (3) is parallel with this edge, as shown in Figure 1, the minimum point of roller (3) is to the distance of base (5) height less than under-chassis (6), angle theta among Fig. 1 is that under-chassis (6) is to the angle that constitutes between roller (3) tangent plane and the ground, the wheel rim of roller (3) exceeds base adjacent thereto (5) inclined-plane that the edge limited, above-mentioned under-chassis (6) bottom, in other words, above-mentioned angle theta is less than the angle that constitutes between described inclined-plane and the ground, and in the time of can guaranteeing casing squint α angle like this, roller (3) lands and plays supporting role, as shown in Figure 3, under-chassis this moment (6) all breaks away from ground with base (5) edge, and when casing (2) was moved in holder, roller (3) rotated, casing (2) is provided with a handgrip (1), makes mobile more convenient reliable like this.

In conjunction with Fig. 3,4, roller (3) middle part is connected with bearing pin (4), two of bearing pin (4) is sat up straight and is crouched in base (5) is gone up the axle bed (7) that is provided with, roller (3) wheel body upper half part is arranged in the wheel chamber (8) at axle bed (7) middle part, axle bed (7) top is circular cavity and matches with bearing pin (4), the bottom links to each other with opening slot (9), the width of groove (9) is slightly less than the diameter of bearing pin (4), this structure mainly is to make assembly technology simple, the bearing pin (4) that is about to be connected with roller (3) upwards is pushed to bearing pin (4) along the opening of above-mentioned groove (9) lower end and sits in the axle bed (7) that crouches, under the self-gravity action of bearing pin (4) and roller (3), pivot pin (4) can not fall along opening slot (9).

As shown in Figure 3, roller (3) is two, and both bearing pins (4) are on the same shaft core line, and two rollers (3) are symmetricly set on the outside of two under-chassis (6).

The utility model is not limited by above embodiment, itself can be made into roll profile as roller (3), just roller landed and can realize the purpose that moves this moment.
