The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
As shown in fig. 1, fig. 1 is a schematic structural view of a washing machine according to an embodiment of the present invention. Referring to fig. 1, the washing machine includes an inner tub 1, an outer tub 2, and a turnover device including two water circulation assemblies capable of pumping out wash water between the inner tub 1 and the outer tub 2 of the washing machine and then re-injecting the wash water into the inner tub 1, thereby promoting turnover of laundry in the inner tub 1. Through the arrangement, the washing machine can fully turn over the clothes, the turning effect of the washing machine on the clothes is enhanced, and the cleaning capability and the user experience of the washing machine are improved.
It should be noted that, although the washing machine of the present embodiment is provided with two water circulation assemblies, it should be understood that other numbers of water circulation assemblies may be provided in the washing machine, and those skilled in the art may reasonably adjust the number of water circulation assemblies according to actual conditions and needs.
With reference to fig. 1, the water circulation assembly includes a water pump 3 disposed at the bottom of the outer tub 2, a circulation water outlet 11 disposed at the bottom of the inner tub 1, and a circulation water inlet 21 disposed at the side wall of the outer tub 2. The water inlet end of the water pump 3 is communicated with the circulation water inlet 21 through a pipeline, and the water outlet end of the water pump 3 can inject the washing water into the inner tub 1 again in a manner of aligning with the circulation water outlet 11. Through the arrangement, the washing water is upwards sprayed from the bottom of the inner barrel to impact the clothes in the inner barrel, so that the clothes in the inner barrel are overturned, and the clothes are washed more comprehensively and cleanly.
It should be noted that the position of the circulation water outlet in the above embodiments is not limited to the bottom of the inner barrel, and may also be arranged at a position close to the bottom of the sidewall of the inner barrel. It can be understood that, the position of the circulating water outlet can be reasonably set by a person skilled in the art according to actual conditions and needs, and the circulating water outlet is arranged at a position lower than that of the circulating water inlet so as to be beneficial to the water pump to pump washing water into the water tank. In addition, it should be noted that the water pump can also be arranged between the inner barrel and the outer barrel, at this time, the arrangement of the circulating water inlet is omitted, and the water inlet end of the water pump directly pumps the washing water between the inner barrel and the outer barrel into the inner barrel again.
It can be understood that when the water pump is arranged at the bottom of the outer barrel, the bottom of the outer barrel is provided with an opening corresponding to the water outlet end of the water pump, and the opening is fixedly connected and communicated with the water outlet end, so that the washing water sprayed out from the water outlet end of the water pump can be smoothly injected into the inner barrel through the circulating water outlet of the inner barrel. In addition, it should be noted that a sealing device is arranged at the joint of the opening of the outer barrel and the water outlet end of the water pump, so as to prevent the washing water from leaking and splashing due to the loose connection of the opening and the water outlet end.
Because the outer barrel is communicated with the inner barrel, the circulation flow of the washing water is as follows in the process of realizing the turnover of the clothes: the washing water in the inner barrel enters the outer barrel and enters a pipeline communicated with the circulating water inlet and the water inlet end of the water pump through the circulating water inlet on the outer barrel, then enters the water inlet end of the water pump through the pipeline, the washing water entering the water pump is sent to the water outlet end of the water pump under the rotation of the impeller of the water pump, and because the outer barrel is provided with an opening fixedly connected and communicated with the water outlet end, the washing water flows through the opening of the outer barrel and is sprayed into the inner barrel through the circulating water outlet on the inner barrel aligned with the water outlet end of the water pump, so that the aim of turning over the clothes in the inner barrel is fulfilled.
Continuing to refer to fig. 1, specifically, the bottom of the inner tub is provided with a pulsator 12, the circulation water outlet 11 is provided at the bottom of the inner tub and is located radially outside the pulsator 12, and the turnover device further includes a positioning lock (not shown) and a controller (not shown). The pulsator 12 is intermittently rotated forward and backward to turn over the laundry in the inner tub 1 when in operation, and the locking device is used to position the inner tub at a position where the circulation water outlet 11 is aligned with the water outlet of the water pump 3 after the inner tub is rotated, so that the water pump injects washing water into the inner tub through the circulation water outlet to facilitate the turning over of the laundry in the inner tub.
The controller is used for controlling the water pump 3 to act in the gap when the impeller 12 stops rotating, and stop acting when the impeller 12 rotates. Through the cooperative action of the water pump and the impeller, the clothes in the inner barrel are continuously overturned under the impact of external force, so that the clothes are more comprehensively washed, and the overturning effect and the cleaning capability of the washing machine on the clothes are improved.
The controller is also used to control the lift and water volume of the water pump 3. The mode that the controller controlled water pump 3 can be frequency conversion control, controls the rotational speed of impeller in water pump 3 through control power supply frequency, then controls the lift and the flow of water pump 3. Specifically, when different washing water levels are adopted, the rotating speed of the impeller of the water pump is controlled by controlling the power supply frequency of the water feed pump, when the water level is high, the lift and the flow of the water pump are large, and when the water level is low, the lift and the flow of the water pump are small, so that the phenomenon that the water is sprayed out of the inner barrel or the clothes are washed out of the inner barrel due to the large water flow and lift is effectively avoided, and the reliability of the washing process of the washing machine is ensured.
As shown in fig. 2, fig. 2 is a plan view of positions of a circulation water inlet and a circulation water outlet of the washing machine according to an embodiment of the present invention. Referring to fig. 2, the washing machine has an angle between a line connecting the two circulation water inlets 21 and a line connecting the two circulation water outlets 11, and as a more preferred embodiment, the line connecting the two circulation water inlets 21 and the line connecting the two circulation water outlets 11 are perpendicular to each other. The water pump 3 sucks the washing water into the water pump 3 from the circulating water inlet 21 by utilizing the suction force of the water pump, at the moment, the clothes and the washing water in the inner barrel 1 also rotate along with the impeller 12 when the impeller 12 rotates, and after the impeller 12 stops rotating, the clothes and the washing water continue to rotate due to inertia, an impact force is given to the circulating water inlet 21 on the side wall, the washing water is pressed into the circulating water inlet 21, the water pumping efficiency of the water pump is improved, meanwhile, the water outlet efficiency of the water pump is indirectly improved, and the clothes turning effect of the washing machine is improved.
It should be noted that the circulating water outlet can be an inclined water outlet forming a certain included angle with the bottom of the inner barrel, so that the washing water is sprayed to the middle upper part of the inner barrel, and the probability and the force of the washing water impacting the clothes are enhanced.
It can be seen that the washing machine of the present invention comprises an inner tub, an outer tub and a turnover device including at least one water circulation assembly. Through the arrangement, the washing machine can fully turn over the clothes, the turning effect of the washing machine on the clothes is enhanced, and the cleaning capability and the user experience of the washing machine are improved. Further, the water circulation assembly comprises a water pump, a circulation water inlet is formed in the side wall of the outer barrel, a circulation water outlet is formed in the position, close to the bottom, of the inner barrel, and an included angle is formed between the circulation water inlet and the circulation water outlet when the top of the washing machine is observed. The water inlet end of the pump is communicated with the circulating water inlet through a pipeline, and the water outlet end of the water pump can inject the washing water into the inner barrel again in a mode of aligning with the circulating water outlet. Through the arrangement, the washing water is upwards sprayed from the bottom of the inner barrel or a position close to the bottom to impact the clothes in the inner barrel, so that the clothes in the inner barrel are overturned, and the clothes are more comprehensively and cleanly washed. Furthermore, the bottom of the inner barrel is provided with a wave wheel, a circulating water outlet is arranged at the bottom of the inner barrel and positioned at the radial outer side of the wave wheel, and the turnover device also comprises a positioning lock and a controller.
