Problems solved by technology

However, the patented technical solution is simply to install the single-phase asynchronous motor installed next to the deceleration clutch of the washing machine directly and vertically below the clutch; since the efficiency of the motor has not been greatly improved, the washing method is single, the function is simple, and its installation and connection are complicated. , high precision requirements, not suitable for mass production, and the washing machine cannot realize frequency conversion rubbing washing, frequency conversion multi-speed dehydration
Another example is that the patent No. ZL00234747.4 discloses a washing machine deceleration clutch directly driven by a brushless motor. It is complex and can only be used in ordinary washing methods. There are many connecting parts of the main parts, and the requirements for clutch installation accuracy are too high, and it has the disadvantage of high failure rate. Therefore, this patented technical solution is not suitable for mass production

Embodiment 1

[0029] Such as figure 1 and figure 2 As shown, a frequency conversion hand rub type motor deceleration clutch device, including: an input shaft 5, a motor rotor 1 fixedly connected to the input shaft 5, the rotor 1 is engaged with or disengaged from the clutch sleeve 3 sliding up and down ; The dehydration shaft 18 is also provided with a brake wheel 12; under the action of the control device, the brake band 15 moves in coordination with the clutch sleeve 3, so that the brake band 15 embraces the brake wheel 12 to make it Brake or release to turn.

[0030] The motor is composed of a rotor 1 connected to the input shaft 5 and an outer rotor 1 motor composed of a stator 2 fixed on the clutch housing 8 . The dehydration shaft 18 is equipped with a clutch sleeve 3 that slides up and down; when the clutch sleeve 3 descends, the clutch sleeve 3 meshes with the rotor 1, so that the rotor 1 drives the dehydration shaft 18 to rotate through the clutch sleeve 3; the clutch sleeve 3 r...

Embodiment 2

[0037] Such as figure 1 and figure 2 As shown, in this embodiment, the clutch sleeve 3 is connected with the traction motor 11 through a control mechanism. Therefore, the clutch sleeve 3 slides up and down under the action of the traction motor 11 , so that the clutch sleeve 3 is switched between the first position and the second position. The control device includes a traction motor 11 that provides control power, a connecting arm 16 that transmits control power to other components, a brake arm 17 that controls the displacement of the brake band 15, and is connected with the gear lever 13 to control The shift fork 10 at the clutch shaft sleeve position. The control displacement output end of the traction motor 11 is connected with the connecting arm 16, the connecting arm 16 is connected with the braking band 15 through the brake arm 17, and the connecting arm 16 is connected with the clutch shaft through the shift fork 10 Sets are connected. The connecting arm 16 is fix...

Embodiment 3

[0046] This embodiment introduces a control method of a frequency conversion hand-rubbing motor deceleration clutch device, which includes: the traction motor drives the connecting arm 16 to generate displacement, so that the brake band 15 is loosened from the brake wheel 12 connected to the dehydration shaft 18, so that The dehydration shaft 18 can rotate freely; it drives the connecting arm 16 to produce secondary displacement, so that the clutch sleeve 3 and the rotor 1 are meshed, so that the dehydration shaft 18 rotates together with the input shaft 5 .

[0047] The deceleration clutch device of the frequency conversion hand rubbing motor includes three states: the first state, the brake band 15 is tightly locked with the brake wheel 12, and the rotor 1 is separated from the clutch sleeve 3. At this time, the input shaft 5 It can rotate with the rotor 1 of the motor, and the dehydration shaft 18 is locked and cannot rotate;

[0048] In the second state, the brake band 15 ...

Abstract

The invention relates to a variable-frequency simulated hand-wash motor reduction clutch and a washing machine. The clutch comprises an input shaft, a dewatering shaft, a clutch housing, a brake wheel, a brake belt, an engaging-disengaging shaft sleeve and a traction motor; the input shaft is connected with a motor rotor; the clutch housing is used for accommodating the input shaft and the dewatering shaft; the brake wheel is disposed on the dewatering shaft; the brake belt fits the brake wheel; the engaging-disengaging shaft sleeve capable of sliding up and down and engaging or disengaging with a rotor is mounted on the dewatering shaft; the brake belt and the engaging-disengaging shaft sleeve are both connected with the traction motor through a control device; the traction motor generates a first displacement and is controlled via the control device to drive the brake belt to move, so that the brake belt turns from holding the brake wheel to loosening the brake wheel and that the dewatering shaft freely rotates; the traction motor generates a second displacement and is controlled via the control device to drive the engaging-disengaging shaft sleeve to move, so that the engaging-disengaging shaft sleeve turns from disengaging with the rotor to engaging with the rotor and that the dewatering shaft rotates with the rotor. The washing machine with the variable-frequency simulated hand-wash motor reduction clutch is provided.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a decelerating clutch device for a frequency-converting hand-rubbing motor and a washing machine. Background technique [0002] Existing technology is installed side by side with washing machine deceleration clutch and single-phase asynchronous motor as the washing machine newly released on the market, by belt pulley and belt transmission. The deceleration clutch of this type of washing machine has low efficiency, high noise, and poor practicability; therefore, relevant technical personnel have proposed a technical scheme in which the motor and the clutch are vertical and coaxially installed. For example, the Chinese utility model patent No. ZL00260194.x discloses a fully automatic washing machine with cup-shaped rotor single-bearing motor and its special clutch device. transmission efficiency. However, the patented technical solution is simply to install the single-phase asynch...
