A washing machine 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.
As shown in fig. 1 to 6, a washing machine 1 according to an embodiment of the present invention includes a cabinet 100, a rotary tub 210, and a water guide cover 220.
The rotary tub 210 is rotatably disposed in the cabinet 100, a water outlet 211 is disposed on a circumferential wall and/or a bottom wall of the rotary tub 210, the water guide cover 220 is disposed on an inner circumferential wall surface of the rotary tub 210, the water guide cover 220 covers the water outlet 211 in a sealing manner, the water guide cover 220 is provided with a water inlet 221, and the water guide cover 220 defines a water guide cavity 240 communicating with the water inlet 221 and the water outlet 211. The liquid rising due to the centrifugal force in the rotary tub 210 enters the water guide chamber 240 through the water inlet 221 and is discharged through the water outlet 211.
Specifically, when the washing machine 1 is dehydrating, the rotating tub 210 rotates, that is, the water guide cover 220 rotates along with the rotating tub 210, the liquid in the rotating tub 210 moves upward under the centrifugal force and enters the water guide chamber 240 through the water inlet 221, and the liquid entering the water guide chamber 240 is guided to the water outlet 211 by the water guide cover 220 and is discharged through the water outlet 211.
According to the washing machine 1 of the embodiment of the present invention, a single tub structure is adopted, that is, only the rotary tub 210 is provided without the water tub, so that water is more water-saving in the rotary tub 210 during washing, and by further providing the water guide cover 220 on the inner circumferential wall surface of the rotary tub 210, and providing the water inlet 221 on the water guide cover 220, and providing the water outlet 211 on the circumferential wall and/or the bottom wall of the rotary tub 210, water in the rotary tub 210 rises under the centrifugal force during dehydration, enters the water guide cover 220 from the water inlet 221, and flows down to the water outlet 211 under the guidance of the water guide cover 220, so as to be discharged through the water outlet 211. Therefore, the dewatering effect can be improved under the conditions of canceling the water containing barrel, simplifying the structure, improving the capacity, reducing the breeding of dirt and bacteria and saving water.
In addition, the water guide cover 220 is connected to the rotary tub 210, and there is no need to provide an additional structure on the cabinet 100 or to provide the cabinet 100 with an internal and external double-layer structure to guide water during the dehydration process, so that the material selection of the cabinet 100 is not limited, for example, metal plates and other materials can be used, thereby greatly improving the appearance.
The water outlet 211 may be provided on the peripheral wall of the rotary tub 210, or may be provided on the bottom wall of the rotary tub 210, or the water outlet 211 may be provided on the peripheral wall and the bottom wall. Specifically, the water outlet 211 is disposed on the circumferential wall of the rotary tub 210, such that the water guide cover 220 covers the water outlet 211 in a sealing manner, and the lower end of the water guide cover 220 is only connected to the circumferential wall of the rotary tub 210, which is beneficial to sealing the water guide cover 220 and the circumferential wall of the rotary tub 210. Certainly, the water outlet 211 in the invention can also be arranged on the bottom wall of the rotary barrel 210, and the water guide cover 220 is covered with the water outlet 211 in a sealing manner, so that the dehydration efficiency in dehydration can be improved, the dehydration effect is good, and the splashing of water from the water outlet 211 can be effectively reduced. The water outlet 211 is formed on the peripheral wall and the bottom wall, which is advantageous for sealing the water guide cover 220 and the peripheral wall of the rotary tub 210, and improving the dehydration efficiency during dehydration, and can effectively prevent water from splashing from the water outlet 211.
Therefore, the washing machine 1 according to the embodiment of the present invention has the advantages of large capacity, water saving, pollution free, low cost, good dewatering effect, beautiful appearance, easy sealing, etc.
A washing machine 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.
As shown in fig. 1 to 6, a washing machine 1 according to an embodiment of the present invention includes a cabinet 100, a rotary tub 210, a water guide cover 220, a pulsator 300, a water tray 400, a driving unit 500, and a support damper assembly 600.
The pulsator 300 is rotatably provided in the rotary tub 210. The water pan 400 is disposed in the cabinet 100 and at least a portion of the water pan is located below the rotary tub 210, and the water pan 400 is used to support the rotary tub 210, and may be directly supported or indirectly supported. In the present embodiment, a driving unit 500 is mounted on the water tray 400, for example, on a lower surface of the water tray 400, for driving at least one of the rotary tub 210 and the pulsator 300 to rotate. The driving unit 500 is provided with a driving shaft assembly 501 penetrating through the water pan 400 and connected and matched with the water pan 400, a supporting plate 502 connected with the driving shaft assembly 501 is arranged between the water pan 400 and the rotary barrel 210, and the supporting plate 502 is fixedly connected with the rotary barrel 210. The water guide chamber 240 guides the liquid thrown out by the rotary tub 210 to the drip tray 400 through the water outlet 211. The water receiving tray 400 may have a water receiving tank 410 therein, and a drain port may be provided at the lowest position of the water receiving tank 410 for draining water, or the water receiving tray 400 may not have a drain port and may use a conduit or the like to lead out water in the water receiving tank 410. The support damper assembly 600 is installed in the cabinet 100 and connected to the drain pan 400.
Therefore, by providing the water receiving tray 400, not only can the liquid discharged from the water guide chamber 240 be received, but also the driving unit 500 and the supporting shock-absorbing member 600 can be mounted on the water receiving tray 400, thereby realizing the functions of supporting the driving unit 500 and supporting the rotary tub 210.
Further, as shown in fig. 1, 5 and 6, the washing machine 1 further includes a balancing ring 230 for keeping the rotating tub 210 balanced when rotating, the balancing ring 230 is disposed at the upper end of the rotating tub 210 and connected to the upper end of the rotating tub 210, the upper end of the water guide cover 220 is adjacent to the balancing ring 230, and the upper end of the water guide cover 220 is spaced apart from the balancing ring 230, the gap may facilitate the installation of the water guide cover 220, and the water inlet 221 is disposed at the upper end of the water guide cover 220. Thus, the water inlet 221 is located below the balance ring 230 and spaced apart from the balance ring 230, so that when the rotary tub 210 rotates, water in the rotary tub 210 enters the water inlet 221 by centrifugal force, and then enters the water guide chamber 240. The upper end of the water guide cover 220 may also be connected to the balancing ring 230, such that the balancing ring 230 and the upper end of the water guide cover 220 define a water inlet 221, and when the rotary tub 210 rotates, water in the rotary tub 210 is facilitated to enter the water inlet 221 by centrifugal force, and thus enters the water guide chamber 240.
In some specific examples of the present invention, as shown in fig. 1 and 5, the upper end of the water guide cover 220 is lower than the upper end of the rotary tub 210, and the height between the upper end of the water guide cover 220 and the upper end of the rotary tub 210 is such that the liquid thrown out from the upper end of the rotary tub 210 enters the water guide chamber 240 through the water inlet 221, thereby preventing the liquid from splashing and spilling at the upper end of the rotary tub 210.
Further, as shown in fig. 1, a side peripheral wall of the water receiving tray 400 extends upward and is higher than the water outlet 211, so that the liquid in the water guide chamber 240 is discharged from the water outlet 211 and then flows into the water receiving tray 400 completely, and the water is prevented from splashing and spilling at the lower end of the rotary tub 210.
In some specific examples of the present invention, as shown in fig. 1, 5 and 6, the circumferential wall of the rotary tub 210 is disposed in parallel with the central axis of the rotary tub 210, and the water guide cover 220 is disposed in parallel with the side wall of the rotary tub 210 and extends in the up-down direction. In other words, the inner diameter of the rotary tub 210 is equal everywhere in the up-down direction, and the outer diameter of the rotary tub 210 is equal everywhere in the up-down direction. It should be understood that the above-mentioned equality is meant to be substantially equal, and it is not excluded that the rotary tub 210 is provided with some relief structure. In other words, the rotary tub 210 is substantially cylindrical.
In some embodiments of the present invention, as shown in fig. 1, 5 and 6, the water inlet 221 is provided at an upper portion of the water guide cover 220, and the water outlet 211 is provided at a lower portion of a circumferential wall of the rotary tub 210. Here, it is understood that the upper portion of the water guide cover 220 refers to a portion above the center of the water guide cover 220 in the vertical direction, and the lower portion of the rotary tub 210 refers to a portion below the center of the rotary tub 210 in the vertical direction. Therefore, when dewatering, the rotating barrel 210 rotates, water in the rotating barrel 210 rises under the action of centrifugal force, the water inlet 221 positioned at the upper part of the water guide cover 220 can better collect the rising water, and the water enters the water guide cover 220 from the water inlet 221 and flows to the water outlet 211 at the lower part of the rotating barrel 210 under the guidance of the water guide cover 220, so that the dewatering efficiency and the dewatering effect are further improved.
Further, as shown in fig. 1, 5 and 6, a water inlet 221 is provided at an upper end of the water guide cover 220 to further facilitate the collection of liquid rising to an upper end of the rotary tub 210 by centrifugal force within the rotary tub 210. The water outlet 211 is formed in the circumferential wall of the rotary tub 210 and is adjacent to the bottom wall of the rotary tub 210, and the water outlet 211 is spaced from the bottom wall of the rotary tub 210 by a predetermined distance, so that the water guide cover 220 is conveniently sealed from the circumferential wall of the rotary tub 210, the height of the side wall of the water tray 400 can be reduced, materials are saved, and the cost is reduced.
Alternatively, the water guide chamber 240 of the water guide cover 220 is defined by the water guide cover 220 alone or by the water guide cover 220 and the inner circumferential wall surface of the rotating tub 210 in combination. In other words, a complete water guide cavity 240 may be defined in the water guide cover 220, and a through hole for communicating the water guide cavity 240 with the water outlet 211 is opened on the water guide cover 220. Alternatively, the water guide cover 220 defines a water guide chamber 240 having an open side therein, and when the water guide cover 220 is mounted on the circumferential wall of the rotary tub 210, the open side of the water guide chamber 240 is closed by the inner circumferential wall surface of the rotary tub 210.
Further, as shown in fig. 1, 5 and 6, in order to improve the drainage effect of the washing machine 1, a plurality of water outlets 211 are provided, a plurality of water outlets 211 are equally spaced along the circumferential direction of the rotary tub 210, a plurality of water guide covers 220 are provided, a plurality of water guide covers 220 are spaced along the circumferential direction of the rotary tub 210, and each water guide cover 220 covers at least one corresponding water outlet 211. For example, the two water outlets 211 are oppositely disposed in the radial direction of the rotary tub 210, the two water guiding covers 220 are oppositely disposed in the radial direction of the rotary tub 210, and the two water guiding covers 220 respectively and correspondingly cover the two water outlets 211 in a sealing manner.
In some embodiments of the present invention, as shown in fig. 2-4, the water guide cover 220 includes a water guide panel 250 and a sealing rim 260. The water guide plate 250 is spaced apart from the inner circumferential wall surface of the rotary tub 210. The sealing edges 260 extend from both side edges and the lower edge of the water guide plate 250 to be adjacent to the inner circumferential wall surface of the rotary tub 210, and the sealing edges 260 are sealingly coupled to the inner circumferential wall surface of the rotary tub 210. The water guide plate 250, the sealing rim 260 and the inner circumferential wall surface of the rotary tub 210 together define the water guide chamber 240.
Further, as shown in fig. 2 to 4, the lower edge of the water guide plate 250 and the bottom of the sealing edge 260 are configured into mutually fitting and downwardly protruding arcs, thereby facilitating the circumferential flow of water in the rotary tub 210 during washing of the washing machine 1, reducing the resistance of the water guide cover 220 to water flow, and preventing the water guide cover 220 from scratching the laundry.
In some specific examples of the invention, the water inlet 211 is provided on the sealing rim 260, as shown in fig. 2-4. Therefore, the water inlet 211 is formed on the side wall (i.e., the sealing edge 260) of the water guide cover 220, the rotary tub 210 rotates during dehydration, the water in the rotary tub 210 rotates and rises under the action of centrifugal force, at this time, the water flows along the circumferential direction of the rotary tub 210 and gradually rises, and the water inlet 211 is formed on the side wall (i.e., the sealing edge 260) of the water guide cover 220, so that the water flowing along the circumferential direction of the rotary tub 210 can smoothly and rapidly enter the water inlet 211, thereby further improving the dehydration effect.
Specifically, as shown in fig. 2, the upper end of the sealing rim 260 is lower than the upper end of the water guide plate 250 to form the water inlet 211 at the upper end of the sealing rim 260. In other words, the water inlet 211 is located at the upper end of the sealing edge 260, a gap formed at a height difference between the upper end of the sealing edge 260 and the upper end of the water guide plate 250 is the water inlet 211, and the upper ends of the sealing edge 260 may be lower than the upper end of the water guide plate 250, so that the water inlets 211 are formed on two side walls of the water guide cover 220.
