Detailed Description

The utility model is described in further detail below with reference to the drawings and the detailed description.

Referring to fig. 1-26, the fruit and vegetable cleaner comprises an outer barrel 1 and an inner barrel 2 for containing fruits and vegetables, wherein the inner barrel 2 is arranged in the outer barrel 1 in a manner of vertically arranging a rotating shaft, a scrubber 3 is arranged in the inner barrel 2, an outer scrubbing part 4 is arranged on the inner side wall of the inner barrel 2, and the outer scrubbing part 4 is usually flexible, can be bristles, can also be flexible sheets (such as soft films and the like) and is optimal. One relatively convenient way of installing the outer brushing member 4 is: as shown in fig. 13, the outer brush member 4 is provided on the brush plate 5, the inner side wall of the inner tub 2 is provided with a slot 6, and the brush plate 5 slides into the slot 6.

In the present utility model, the "inner tub is disposed in the outer tub with its rotation axis vertically" does not strictly require that the rotation axis of the inner tub be completely vertical, and when the inner tub 2 is disposed in the outer tub 1 with its rotation axis inclined but still substantially vertically, it still belongs to the case where the "inner tub is disposed in the outer tub with its rotation axis vertically", as shown in fig. 18, for example.

The fruit and vegetable cleaner also comprises a driving mechanism, wherein at least part of the scrubber 3 is rotatably arranged in the inner barrel 2, and the driving mechanism drives the scrubber 3 and the inner barrel 2 to rotate. The inner tub 2 is generally cylindrical in vertical arrangement, and the inner tub 2 rotates around its center axis. Of course, the inner tub 2 may be in other shapes, for example, the inner tub 2 in fig. 14 is in an oval cylindrical shape with an oval cross section, the inner tub 2 rotates around its center, and at this time, a circulation flow channel of fruits and vegetables is formed in the inner tub 2, so that fruits and vegetables can substantially pass through between the outer brushing member 4 and the scrubber 3 in a part, and a better cleaning effect can be obtained.

The rotation direction of the inner tub 2 may be opposite to the rotation direction of the scrubber 3, and when the rotation direction of the inner tub 2 is opposite to the rotation direction of the scrubber 3, the scrubbing direction of the scrubber 3 on the fruits and vegetables is opposite to the scrubbing direction of the outer scrubbing part 4 of the inner tub 2, so that an effect similar to "scrubbing" can be generated to obtain a better cleaning effect.

The rotation direction of the inner barrel 2 and the rotation direction of the scrubber 3 can be the same, when the rotation direction of the inner barrel 2 and the rotation direction of the scrubber 3 are the same, the scrubbing direction of the scrubber 3 on fruits and vegetables and the scrubbing direction of the outer scrubbing part 4 of the inner barrel 2 on fruits and vegetables are the same, which is beneficial to the operation of the fruits and vegetables in the inner barrel 2, and can also obtain better cleaning effect.

The barrel body of the inner barrel 2 can be provided with an opening 26 through which cleaning liquid can circulate, and can be not provided with an opening. When the opening 26 is formed in the barrel body of the inner barrel 2, the cleaning solution is contained in the outer barrel 1, and the inner barrel 2 is immersed in the cleaning solution to facilitate the rotation of the inner barrel 2. Preferably, the opening 26 is only formed on the bottom surface of the inner tub 2, so as to reduce the resistance of water when the inner tub rotates. Of course, the barrel body of the inner barrel 2 may not be perforated, for example, as shown in fig. 7, the cleaning solution is contained in the inner barrel 2, and the cleaning solution can be saved relatively.

The inner brushing member 8 is generally flexible, either as bristles or as a flexible sheet (e.g., soft film, etc.), with bristles being preferred.
