Description

TECHNICAL FIELD

[0002] The existing laundry treatment devices such as washing machines, dryers and ironing machines generally use water, laundry additives and mechanical operations to perform washing and treatment on laundry, so that the laundry achieves the expected washing and treatment effect. With the improvement of the automation level of laundry treatment devices, the technology of automatic feeding of additives such as detergents, softeners and bleaching agents in the laundry treatment devices is becoming more and more mature. It has become more and more popular to provide an additive feeding device on the laundry treatment device for automatically feeding the additives such as detergents and softeners into the water tub through the water feeding pipeline of the laundry treatment device.

[0003] The existing detergent feeding device of the washing machine has the following problems: since the additive feeding device is only provided as a separate body, it is limited by the internal space size of the laundry treatment device, so that the overall volume of the additive feeding device is limited, a larger number of feeding cavities cannot be provided, and the feeding of more types of additives cannot be achieved. At the same time, since the additive feeding device is only provided as a single body, a lot of spare space inside the shell of the laundry treatment device cannot be used by the additive feeding device, which not only causes space waste, but also reduces the capacity of the additive feeding device to accommodate additives.

[0004] If multiple feeding boxes are added to the washing machine, although the number of types of detergents that can be fed can be increased, the increased number of feeding boxes will occupy too much space of the washing machine. In particular, the provision of multiple feeding boxes requires the installation of a separate set of water feeding pipelines for feeding water into the drum for each feeding box, which makes the water feeding pipeline structure of the washing machine more complex.

[0005] In addition, the applicant previously proposed an inner tub washing machine with a hole-free inner tub, so that during the execution of the washing process of the washing machine, the washing water is contained in the drum, and the washing water does not flow crosswise between the inner and outer tubs, thereby solving the problem of secondary pollution of laundry by dirt between the inner and outer tubs. Therefore, how to install a drum washing machine with multiple feeding boxes and a simplified water feeding pipeline on the above-mentioned hole-free drum washing machine has become a technical problem that needs to be solved urgently.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0040] The present application introduces a kind of washing machine, the washing machine is any form of existing, at least can be carried out washing treatment to clothes drum washing machine;The drum washing machine includes, housing;Housing is installed with drum;Drum bottom seal, sealing end is connected with the drum shaft that extends outward and protrudes, drum shaft can be rotated around the shaft and be installed on support piece 6, and be connected with the motor rotor installed on support piece 6 directly or through speed reducer clutch, to make that drum can be rotated around the shaft and be installed in clothes processing equipment driven by motor.The support piece 6 can be the outer cylinder of the sleeve drum, can also be other support components.

[0041] The laundry washing machine in the embodiment of the present application can be a normal drum washing machine, the drum is an inner drum with a normally open dewatering hole, and an outer drum filled with water is sleeved outside the drum, the water in the drum is made to flow crosswise between the inner drum and the outer drum by means of the dewatering hole in the drum, and the effects of washing, dewatering, draining and the like of the laundry in the drum are achieved. Of course, the laundry washing machine in the embodiment of the present application can also be the holeless drum washing machine proposed by the applicant previously; for example, a drum cover that can be opened and closed is arranged at the drum opening of the drum, the drum cover is fastened to correspondingly seal and close the drum opening of the drum after being fastened, and no normally open hole is arranged on the drum, so that the holeless drum in the form of a sealed water container is formed after the drum cover is fastened, so that the water in the holeless drum is not drained out when the laundry processing device executes the washing program, and the water in the drum is used to wash and process the laundry. In addition, in the embodiment of the present application, the drum cover that can be opened and closed is not arranged at the drum opening of the drum, and the drum opening is arranged as a normally open drum opening like a common drum, so that the rotation speed of the drum is controlled during the washing process, so that the washing water and the laundry in the drum are not affected by the agitation of the rotating drum and flow out of the drum opening, and the same effect of the above-mentioned laundry processing device forming the holeless drum washing machine between the inner drum and the outer drum without cleaning can be achieved. At the same time, in order to achieve the execution of the washing, rinsing and dewatering programs of the laundry processing device on the laundry in the holeless drum, a drain opening is arranged on the holeless drum, and a controllable opening and closing valve body mechanism is installed at the drain opening, so that the drain opening of the holeless drum is controllably opened and closed, the water in the holeless drum is controllably drained outwards, and the purpose of draining the water in the holeless drum during the execution of the dewatering program is achieved. The controllable opening and closing valve body mechanism installed at the drain opening can be any valve body mechanism that can control the opening and closing of the drain opening; for example, a centrifugal drainage mechanism is installed at the drain opening, so that when the rotation speed of the holeless drum reaches a set rotation speed V0, the centrifugal force of the rotating holeless drum drives the centrifugal drainage mechanism to open the drain opening, and the water in the holeless drum is drained outwards through the opened centrifugal drainage mechanism to the outside of the drum. Of course, the controllable opening and closing valve body mechanism can also be other valve body structures, for example, an electromagnetic switch valve arranged at the drain opening, a positioning mechanical valve arranged at the drain opening and the like can also be achieved. In the embodiment of the present application, in order to facilitate description, the controllable opening and closing valve body mechanism is taken as an example of the centrifugal drainage mechanism to be discussed: at least one drain opening is arranged on the drum wall of the holeless drum, and a centrifugal drainage mechanism is installed at the drain opening; the centrifugal drainage mechanism comprises: a valve plug corresponding to the drain opening; the valve plug is connected with a centrifugal block through a connecting rod, and the connecting rod is hinged with the holeless drum to form a crowbar structure; at the same time, a return spring is arranged between the valve plug and the holeless drum, which is used to drive the valve plug to move towards the closed drain opening or to keep it in the closed position. Through the above arrangement, when the holeless drum rotates below the set rotation speed V0, the valve plug corresponds to the closed drain opening, and the drum is used for water storage; when the rotation speed of the holeless drum reaches V0, the centrifugal block is driven to move the valve plug by the centrifugal force, and the drain opening is correspondingly opened, so that the free water in the holeless drum is drained outwards.

[0042] Meanwhile, in the embodiment of the present application, the drum is also connected with a water inlet channel 2 for the water flow and / or the detergent mixture of the laundry treatment equipment to enter the drum; the water inlet channel 2 can be arranged as follows: a drum shaft 51 is connected at the bottom of the drum, the drum shaft 51 is a sleeve structure, the hollow channel 23 inside the drum shaft 51 constitutes at least part of the water inlet channel 2 of the washing machine, the two ends of the water inlet channel 2 are respectively connected with the water inlet channel unit of the laundry treatment equipment and the inside of the drum, so that the water flow and / or the detergent mixture of the laundry treatment equipment flows into the drum through the above-mentioned water inlet channel 2; meanwhile, in order to realize the effect of spraying the water flow and / or the detergent mixture into the drum, a water inlet nozzle 52 can be installed at the bottom of the drum, the water inlet nozzle 52 is connected with the outlet of the water inlet channel 2, so that the water flow and / or the detergent mixture is uniformly sprayed on the laundry in the drum through the spray holes formed on the water inlet nozzle 52.

[0043] Of course, the water inlet channel 2 can also be connected with other positions of the drum to adapt to the introduction of the water flow and / or the detergent mixture into the drum.

[0044] For example, the drum opening is not provided with an openable drum cover, but only with a normally open drum opening, the outlet of the water inlet channel 2 is arranged at the drum opening and connected with a nozzle having spray holes facing the inside of the drum, so that the water flow and / or the detergent mixture is sprayed from the drum opening and flows into the drum.

[0045] Alternatively, an annular water inlet cavity is arranged between the drum wall and the outer drum wall, part of the annular water inlet cavity rotates with the drum, and the other part is fixedly connected with the outer drum, the water inlet cavity has a spraying opening connected with the inside of the drum and an inlet connected with the water inlet structure of the laundry treatment equipment, so that the annular water inlet cavity is connected with the outlet of the water inlet channel 2, and the water flow and / or the detergent mixture is sprayed from the drum wall and flows into the drum.

[0046] Alternatively, the water inlet channel 2 can also be arranged in other structures that can introduce water into the drum rotating around the shaft.

[0047] In order to facilitate description, the outlet of the water inlet channel 2 of the washing machine is connected with the bottom of the drum as an example: a drum shaft 51 is connected at the bottom of the drum, the drum shaft 51 is a sleeve structure, the inside of the sleeve structure of the drum shaft 51 has a hollow channel 23, the two ends of the hollow channel 23 are respectively connected with the inside and outside of the drum, and the two ends of the hollow channel 23 are respectively connected with the water inlet channel structure of the washing machine and the inside of the drum, so that the water flow and / or the detergent mixture of the washing machine enters the drum of the washing machine.

[0048] The hollow channel 23 in the sleeve-shaped drum shaft 51 constitutes part of the water inlet feeding channel 2 to spray and feed the washing machine water flow and / or the detergent mixture introduced by the feeding device of the washing machine into the washing machine drum, thereby achieving the effect of water washing or spraying detergent mixed washing on the clothes in the drum.

[0049] As shown in Figures 1 to 4 The feeding waterway structure of the washing machine in the embodiment of the application comprises a detergent feeding device. The detergent feeding device comprises at least two feeding boxes 1, each of which is provided with a liquid storage box that can be pulled outwards, and at least one liquid storage cavity for storing detergent is arranged in the liquid storage box. A feeding waterway 101 is arranged on each feeding box 1, and the feeding waterway 101 is in communication with the liquid storage cavity. A suction pump, a negative pressure pipe or other structures can be used to extract the detergent in the liquid storage cavity into the feeding waterway 101. At the same time, the feeding waterway 101 is connected with the water inlet valve 7 of the washing machine, so that the feeding water flow can flow into the feeding waterway 101 in a controllable on-off manner, and the feeding water flow and the extracted detergent are mixed in the feeding waterway 101 to form a detergent mixture, and the detergent mixture is then fed out of the feeding box 1 through the feeding waterway 101. In addition, the detergent can also not be fed into the feeding waterway 101, and only the water inlet valve 7 is opened to feed water into the feeding waterway 101. The water flow flows out of the feeding waterway 101 and flows into the drum of the washing machine, so as to realize the effect of water feeding into the drum of the washing machine. Of course, a plurality of feeding waterways 101 can also be arranged on different feeding boxes 1, and each feeding waterway 101 can be used to feed different types of detergent. In addition, in order to avoid the residue of the detergent in the feeding waterway 101 after the detergent is fed, a flushing waterway 102 needs to be arranged on the feeding box 1. The flushing waterway 102 is also connected with the water inlet valve 7 of the washing machine, so that the flushing water flow can flow into the flushing waterway 102 in a controllable on-off manner. The flushing waterway 102 is connected with the feeding waterway 101, so that the flushing water flow flows through the feeding waterway to flush the residual detergent in the feeding waterway 101, thereby achieving the remarkable technical progress of preventing the detergent from being left in the waterway arranged on the feeding box 1. The water inlet valves 7 connected with the above-mentioned waterways can be different water inlet valves, and each water inlet valve is connected with the water inlet pipe of the washing machine in a controllable on-off manner, so as to selectively or combinedly supply water to different waterways of different feeding boxes in a controllable on-off manner.

Through the above setting, the effect that the water flow and / or the detergent mixture supplied by the different feeding boxes is fed into the drum through the same water feeding feeding channel is realized, and the design of the water feeding path of the washing machine provided with the multiple types of detergent feeding device is greatly simplified. In addition, the single water feeding feeding channel 2 provided on the drum washing machine is reversibly connected with the water paths of the different feeding boxes 1, so that the different feeding boxes 1 can share the same water feeding feeding channel 2 to feed water and / or feed detergent into the drum, and the effect that the multiple different feeding boxes 1 provided on the washing machine can share the same water feeding feeding channel 2 is realized.
