Description

Technical field:

[0001] The present invention relates to the technical field of mechanical knob indicating device equipment, and in particular to a three-circular bearing type indicating knob assembly and a washing machine. Background technology:

[0002] The indicator knobs on the current washing machine control panel are mostly circular in structure and rotate around the center. The indicator parts installed on the indicator knobs divide the entire indicator knob, causing a visual gap and a lack of aesthetic appeal.

[0003] Therefore, it is necessary to improve the existing technology to solve the shortcomings of the existing technology. Summary of the invention:

[0004] The present invention is to solve the problems existing in the above-mentioned prior art and provides a three-circle bearing type indicator knob assembly and a washing machine. A track is formed between the outer circle of the main track and the inner circle of the main track on the knob body. When the knob assembly rotates around the center, the double-circle shape of the knob body ensures that the visual appearance of the knob body does not change, and the ball indicator runs on the track like a ball.

[0005] The present invention adopts the following technical solution: a three-circular bearing type indicator knob assembly, including a knob body and a front ball indicator installed on the knob body, a main body track outer circle and a main body track inner circle are formed on the front surface of the knob body, a track is formed between the main body track outer circle and the main body track inner circle, an indicator slot is formed on the knob body at the position of the track and passes through the front and rear directions, and the front ball indicator is installed in the indicator slot.

[0006] Furthermore, the indicator member slot is in a step-like shape, and includes a front indicator member slot and a rear indicator member slot connected front to back.

[0007] Furthermore, the diameter of the front slot of the indicator is smaller than the diameter of the rear slot of the indicator.

[0008] Furthermore, the diameter of the outer circle of the main body track is the same as the diameter of the outer edge of the knob body.

[0009] Furthermore, the front ball indicator includes an indicator portion and a first indicator fixing card and a second indicator fixing card extending backward from the rear surface of the indicator portion. The ends of the first indicator fixing card and the second indicator fixing card are both folded outward to form a buckle portion.

[0010] Furthermore, the buckle portions on the first indicator fixing card and the second indicator fixing card are both buckled at positions where the front indicator slot and the rear indicator slot are connected.

[0011] Furthermore, the indicating portion is located outside the indicator slot and in the track.

[0012] Furthermore, reinforcing ribs are formed between the indicating portion and the first indicating member fixing clip, and between the indicating portion and the second indicating member fixing clip.

[0013] Furthermore, an encoder column and a main body mounting piece located outside the encoder column are formed in the middle position of the rear surface of the knob body, and a first main body anti-detachment buckle and a second main body anti-detachment buckle are formed on the outer surface of the main body mounting piece.

[0014] The present invention also adopts the following technical solution: a washing machine, characterized in that it includes the aforementioned three-circular bearing type indicator knob assembly.

[0015] The present invention has the following beneficial effects: the three-circular bearing type indicator knob assembly of the present invention refers to the bearing ball rolling principle, and designs the front ball indicator to be a centrally symmetrical structure, which is matched with the knob body to achieve the rolling effect of the indicator. Compared with the abrupt design structure of the traditional knob that divides the knob body and causes a visual structural fault, the present invention integrates the indicator in the form of a ball into the knob body, which can better reflect the integrity, playability and appearance of the knob assembly.

[0020] Figure 5 This is a schematic diagram of the front ball indicator. Specific implementation method:

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] The three-circular bearing type indicator knob assembly of the present invention includes a knob body 1 and a front ball indicator 2 mounted on the knob body 1. A main track outer circle 10 and a main track inner circle 11 are formed on the front surface of the knob body 1, wherein the diameter of the main track outer circle 10 is the same as the diameter of the outer edge of the knob body 1. A track 12 is formed between the main track outer circle 10 and the main track inner circle 11. An indicator slot 13 is formed on the knob body 1 at the position of the track 12, which is through the front and back directions. The indicator slot 13 is stepped and includes a front indicator slot 130 and a rear indicator slot 131 connected front and back. The diameter of the front indicator slot 130 is smaller than the diameter of the rear indicator slot 131.

[0023] An encoder column 14 and a main body mounting member 15 located outside the encoder column 14 are formed in the middle position of the rear surface of the knob body 1, and a first main body anti-detachment buckle 150 and a second main body anti-detachment buckle 151 are formed on the outer surface of the main body mounting member 15.

[0024] The front roller indicator 2 includes an indicator portion 20 and opposing first and second indicator fixing clips 21, 22 extending rearward from the rear surface of the indicator portion 20. The ends of the first and second indicator fixing clips 21, 22 are folded outward to form a snap-on portion 23. To strengthen the entire front roller indicator 2, reinforcing ribs 24 are formed between the indicator portion 20 and the first and second indicator fixing clips 21, 22. When the front roller indicator 2 is installed in the indicator slot 13, the snap-on portions on the first and second indicator fixing clips 21, 22 snap into place where the front and rear indicator slots 130, 131 meet. The indicator portion 20 is located outside the indicator slot 13 and within the track 12.

[0025] The three-circular bearing indicator knob assembly of the present invention is installed on the washing machine through the encoder column 14, the first main body anti-detachment buckle 150, and the second main body anti-detachment buckle 151. The assembly relationship here is common knowledge in the field and will not be repeated here. Because the front ball indicator 2 is fixed to the knob body 1, when the knob body 1 is rotated, the main body track outer circle 10 and the main body track inner circle 11 on the knob body 1 remain visually unchanged. The front ball indicator 2 rotates with the knob body 1, and the visual appearance is that the front ball indicator 2 rolls on the track between the main body track outer circle 10 and the main body track inner circle 11, which better reflects the integrity, playability and aesthetic appearance of the knob assembly.

[0026] The above description is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principles of the present invention. These improvements should also be regarded as the scope of protection of the present invention.
