Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

A control method of a laundry treating apparatus according to an embodiment of the present invention will be described in detail with reference to fig. 1 to 27.

As shown in fig. 1 to 3 and fig. 26, the control method of the laundry treating apparatus according to the embodiment of the present invention includes the steps of: step S1: the first signal is detected, and the supporting disk in the inner drum of the clothes processing equipment is controlled to rotate under the condition that the first signal is detected, and the supporting disk rises or falls along a preset track arranged on the inner surface of the inner drum.

For example, in some embodiments, the first signal may be a lifting signal in a lifting phase of the laundry treating apparatus. Specifically, a lifting signal is detected before the inner barrel enters a lifting stage, and if the lifting signal is detected, the supporting disk is controlled to rotate and ascend along a preset track of the inner surface of the inner barrel; if the lifting signal is not detected, the current stage is continuously executed and the lifting signal is detected. Specifically, the washing program of the laundry treating apparatus may be timed, and when the stage before entering the lifting stage is performed for a predetermined time, for example, 20 minutes, the laundry treating apparatus may be controlled to jump to the lifting stage, so as to raise the height of the laundry in the inner tub, so that the user does not need to bend down to take the laundry.

In other embodiments, the first signal may be a lift signal in a washing phase of the laundry treatment apparatus. In the washing stage, the support plate is controlled to rotate according to the detected lifting signal and rises or falls along a preset track arranged on the inner surface of the inner barrel, so that the three-dimensional stirring effect of water flow is realized, and the washing effect of clothes is improved.

The control method of the laundry treating apparatus further includes step S2: and detecting a second signal, controlling a support plate in an inner drum of the clothes treatment equipment to rotate under the condition that the second signal is detected, and driving the inner drum to rotate together. Here, the steps S2 and S1 are merely reference numerals for distinguishing different steps, and do not indicate the execution order of the steps, and for example, the step S1 may be executed before the step S2 or after the step S2.

In this embodiment, the second signal may be a dehydration signal, for example, a time of a washing program of the laundry treatment apparatus may be set, and when a stage before entering the dehydration stage is executed for a predetermined time, for example, 20 minutes, the laundry treatment apparatus may be controlled to jump to the dehydration stage, and the support plate and the inner drum are controlled to be driven to rotate together by the same driving structure without separate driving of a plurality of driving structures.

It should be noted that the terms "detecting the first signal" and "detecting the second signal" in the present invention are not directly and unambiguously determined by the structural features of the present invention described later, for example, in the structure of the present invention described later, the on/off of the clutch device can be directly obtained through the power-on and power-off processes, and therefore, the operation steps of "detecting the first signal" and "detecting the second signal" cannot be directly and unambiguously obtained only by the structural features of the present invention described later.

According to an embodiment of the present invention, the step S1 and/or the step S2 includes: controlling the clutch device of the clothes treatment equipment to act so as to enable the driving device of the clothes treatment equipment to be jointed with the supporting plate; the control driving device drives the supporting disc to rotate.

For example, in step S1, the clutch device of the laundry processing apparatus is first controlled to switch to the engaged state, so that the driving device is engaged with the support plate, and then the driving device is controlled to drive the support plate to rotate and to move the support plate up or down along a predetermined track provided on the inner surface of the inner drum. Similarly, when step S2 is executed, the clutch device of the laundry processing apparatus is first switched to the engaged state, so that the driving device is engaged with the support plate, and then the driving device is controlled to drive the support plate to rotate, and the inner drum is rotated together with the support plate.

In some embodiments, before controlling the driving device to drive the supporting disc to rotate, the method further includes: whether the clutch device acts in place or not is detected, and whether the clutch device acts in place or not is detected, so that the driving device and the supporting plate are controlled to rotate after the driving device and the supporting plate are jointed in place, and normal work of the clothes treatment equipment is guaranteed.

In some embodiments, the clutch device includes a driving part and a driven part, the driving part is connected with the driving device, the driven part is connected with the supporting plate, and detecting whether the clutch device is in place includes: whether the distance between the driving part and the driven part is smaller than a preset value is detected. Specifically, if the distance between the driving part and the driven part is detected to be smaller than a preset value, the clutch device is judged to be in place, and if the distance between the driving part and the driven part is detected to be larger than or equal to the preset value, the clutch device is judged to be not in place.

Step S1 further includes: detecting whether the supporting disc ascends or descends to a preset position or not; and under the condition that the ascending or descending of the support disc to the preset position is detected, controlling the driving device to stop working or controlling the driving device to drive the support disc to rotate reversely.

For example, in the lifting stage, when the support plate is detected to rise to the preset position, the driving device is controlled to stop working, so that the support plate stops rotating and stays at the preset position, and a user can take out clothes conveniently. In the washing stage, if the supporting disc is detected to rise to the preset position, the driving device is controlled to drive the supporting disc to rotate reversely, so that the supporting disc descends along the preset track on the inner surface of the inner cylinder, and if the supporting disc is detected to descend to the preset position, the driving device is controlled to drive the supporting disc to rotate reversely, so that the supporting disc ascends along the preset track on the inner surface of the inner cylinder, and the operation is repeated, so that the three-dimensional shifting effect of water flow is realized.

In some embodiments, a telescopic transmission shaft is connected between the support plate and the driving device, and detecting whether the support plate ascends or descends to a preset position comprises: whether the transmission shaft reaches a preset height is detected. Specifically, if the height of the transmission shaft is detected to reach the preset highest position and/or the preset lowest position, the driving device is controlled to stop working or the driving device is controlled to drive the supporting disc to rotate reversely, the control logic is simple, and the normal work of the clothes treatment equipment is ensured.

The second shaft 62 is connected to the first shaft 61 and the pulsator 30, respectively, so that the pulsator 30 can be rotated together with the first shaft 61 by the second shaft 62. Further, the second shaft 62 is slidable in the axial direction of the first shaft 61, so that the height of the pulsator 30 in the inner tub 11, and thus the height of the supporting plate 20 in the inner tub 11, can be changed.

In some embodiments, the first shaft 61 has a hollow cavity 610 extending along an axial direction thereof, and the second shaft 62 is inserted into the hollow cavity 610, wherein one of an inner peripheral wall of the first shaft 61 and an outer peripheral wall of the second shaft 62 has a sliding protrusion 621, and the other one has a sliding groove 611 matched with the sliding protrusion 621, and by providing the sliding protrusion 621 and the sliding groove 611 matched with each other, the second shaft 62 can be limited, and the sliding matching of the second shaft 62 and the first shaft 61 can be realized, so that the second shaft 62 can extend and retract in the first shaft 61.
