Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
It should also be noted that, in the description of the present invention, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. 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 and 2, the drum washing machine of the present invention mainly includes a cabinet 1, an outer tub 2, an inner tub 3, a door 4, a sealing window gasket 5, a drain pump 6, and a drain pipe 7. Wherein the outer cylinder 2 is fixedly disposed inside the cabinet 1, the inner cylinder 3 is rotatably disposed in the outer cylinder 2, and the sealing window gasket 5 is disposed between the cabinet 1 and the outer cylinder 2. The drain pump 6 and the drain pipe 7 are both arranged in the box body 1, a water inlet of the drain pump 6 leads to the inner bottom of the outer cylinder 2, a water outlet of the drain pump 6 is connected with one end of the drain pipe 7, and the other end of the drain pipe 7 leads to the outside. The drain pump 6 can drain the washing water in the outer tub 2 through the drain pipe 7.
Further, as will be understood by those skilled in the art, when each portion of the drain pipe 7 is lower than the inner bottom end of the outer tub 2, those skilled in the art can omit the drain pump 6 and replace the drain pump 6 with a shut-off valve as needed. When the drum washing machine needs to drain, the cut-off valve is opened, so that the washing water in the outer tub 2 is automatically drained from the drain pipe 7 under the action of self gravity.
With continued reference to fig. 1 and 2, the front end of the box body 1 (the right side of the box body 1 in fig. 2) is provided with a box body opening (not shown), the front end of the outer cylinder 2 (the right side of the outer cylinder 2 in fig. 2) is provided with an outer cylinder opening (not shown), and the front end of the inner cylinder 3 (the right side of the inner cylinder 3 in fig. 2) is provided with an inner cylinder opening (not shown). One end of the sealing window gasket 5 is connected with the edge of the box body opening in a sealing mode, and the other end of the sealing window gasket 5 is connected with the edge of the outer cylinder opening in a sealing mode. The door 4 is pivotally provided on the cabinet 1, and the door 4 can close the cabinet opening when closed, preventing the washing water in the tub 2 from overflowing from the cabinet opening.
With continuing reference to fig. 1 and 2, the drum washing machine of the present invention further includes a circulation motor (not shown), a circulation pump 8, a water outlet pipe 9, a pressure equalizer 10, a plurality of branch pipes 11, and a plurality of nozzles 12. Wherein, circulating motor and circulating pump 8 drive connection, circulating motor are used for driving circulating pump 8 to rotate. The circulation pump 8 is preferably arranged within the tank 1 and is fixedly connected to the tank 1. The water inlet of the circulation pump 8 opens into the interior of the outer tub 2, and preferably the water inlet of the circulation pump 8 is connected with the bottom end of the outer tub 2 through a water inlet pipe (not shown). Or the person skilled in the art can connect the water inlet pipe to any position of the outer cylinder 2, if necessary, while ensuring that the water inlet pipe is located below the liquid level in the outer cylinder 2. The water outlet of the circulating pump 8 is communicated with the water inlet of the pressure equalizer 10 through the water outlet pipe 9. Or, the person skilled in the art can omit the water outlet pipe 9 according to the requirement, so that the water outlet of the circulating pump 8 is directly communicated with the water inlet of the pressure equalizer 10.
With continued reference to fig. 1 and 2, the pressure equalizer 10 is disposed in the tank 1 and is fixedly connected to the tank 1 (e.g., the inner sidewall of the tank 1). Further, the pressure equalizer 10 may be fixedly connected to the outer cylinder 1 as needed by those skilled in the art. The pressure equalizer 10 includes a plurality of water outlets (not shown). Each water outlet of the pressure equalizer 10 is communicated with a nozzle 12 through a branch pipe 11. Alternatively, one skilled in the art may provide the pressure equalizer 10 with a spare water outlet, if necessary, while ensuring that each nozzle 12 is communicated with one water outlet of the pressure equalizer 10.
In operation, as indicated by the arrows in fig. 2, the circulation pump 8 pumps the washing water in the tub 2 to the pressure equalizer 10 under the action of the circulation motor, and the pressure equalizer 10 is equally distributed to the plurality of nozzles 12 through the plurality of branch pipes 11. The plurality of nozzles 12 spray wash water into the drum 3 to wash the laundry. When the drum 3 is operated at high speed, the water stream ejected from the nozzle 12 can rapidly pass through the laundry and enter the tub 2 under the centrifugal force and gravity. It will be understood by those skilled in the art that the purpose of the pressure equalizer 10 to equally distribute the washing water to the plurality of nozzles 12 is to equalize the water pressure in each spray pipe 12 and the water output, so that the plurality of nozzles 12 can form an annular water curtain of washing water uniformly sprayed into the inner tub 3. It should be noted that, since the voltage equalizer is a component known to those skilled in the art, the description thereof will not be made herein too much.
In addition, the skilled person can omit the pressure equalizer 10 according to the actual requirement, so that the plurality of nozzles 12 can inject the washing water into the inner tub 3 in unequal amounts.
As shown in fig. 1, a plurality of nozzles 12 are provided on the sealing window gasket 5 at equal intervals around the circumferential direction of the outer cylinder 2. Alternatively, the plurality of nozzles 12 may be disposed on the sealing gasket 5 at unequal intervals as required by those skilled in the art. Wherein all the nozzles 12 pass through the sealing window gasket 5 and are sealingly coupled with the sealing window gasket 5 to prevent the washing water in the tub 2 from leaking. At the same time, the connection between the nozzle 12 and the sealing gasket 5 also has a positioning effect on the nozzle 12.
Further, a person skilled in the art may also dispose the plurality of nozzles 12 at any position near the front end of the outer cylinder 2 as needed, for example, dispose the plurality of nozzles 12 inside the door 4 and dispose the plurality of nozzles 12 at the edge of the outer cylinder opening.
As shown in fig. 1 to 3, each branch pipe 11 has a flexible telescopic joint structure so that all nozzles 12 can accommodate the vibration of the sealing gasket 5. Alternatively, the branched pipe 11 may be provided as a flexible pipe by those skilled in the art as needed. Furthermore, the inner diameter of the branch pipe far from the circulation pump 8 may be larger than that of the branch pipe near the circulation pump 8, as required by those skilled in the art, so that the water flow from all the nozzles 12 is substantially uniform.
As shown in fig. 1 to 3, the water outlet of each nozzle 12 is directed to the opening of the inner drum 3, so that the water sprayed from the nozzle 12 can fall into the inner drum 3 to spray the clothes. Alternatively, one skilled in the art can also direct the nozzles 12 toward the door 4 on the premise that the plurality of nozzles 12 can spray the washing water into the inner tub 3, and then spray the washing water into the inner tub 3 by means of the reflection action of the door 4, as needed.
The spray control method of the present invention will be described in detail with reference to fig. 4 to 13.
As shown in fig. 4, the spray control method of the present invention mainly includes:
s100, selecting a rotating speed gear of a circulating motor;
step S200, operating the circulation motor according to the selected rotation speed gear, so that the plurality of nozzles 12 provide the corresponding lifts for the washing water and thus spray the washing water to the corresponding positions in the drum 3.
Before step S100, the spray control method of the present invention further includes the steps of: the circulating motor is electrified and operated.
In a preferred embodiment of the invention, the circulating electric machine comprises six rotational speed gears. Step S100 therefore specifically includes selecting one of the six rotational speed steps and setting the electric circulation machine to this rotational speed step.
Specifically, in step S200, the spray nozzle 12 sprays the washing water to a corresponding position in the inner tub 3 according to the rotation speed gear at which the circulation motor is currently located.
It will be appreciated by those skilled in the art that the rotational speed gear adjustment of the cycle motor can be either manually operated by the user; or can be operated by a controller on the drum washing machine according to a certain instruction and automatically adjusted according to a certain rule.
Illustratively, the cabinet 1 is provided with an operating button which is in communication with a controller on the drum washing machine, which is in turn in communication with the circulation motor. When a user operates the operation button, the operation button sends an operation instruction of the user to the controller, and the controller controls the circulating motor to adjust to the corresponding rotating speed gear.
The spray control method of the present invention will be exemplified below with reference to fig. 5 to 10.
It should be noted that, among the six rotational speed gears, the rotational speeds of the cycle motor corresponding to the first rotational speed gear, the second rotational speed gear, the third rotational speed gear, the fourth rotational speed gear, the fifth rotational speed gear, and the sixth rotational speed gear sequentially increase. As the rotation speed of the circulation motor increases, the rotation speed of the circulation pump 8 also gradually increases, and at the same time, the flow rate of the washing water pumped to the plurality of nozzles 12 also increases, and thus the head of the washing water sprayed from each nozzle 12 also increases.
As shown in fig. 5, the circulation motor is adjusted to the first rotation speed, the plurality of nozzles 12 provide a first lift for the washing water, so that the washing water is sprayed into the front portion of the inner tub 3 to form an annular water curtain, and the clothes in the front portion of the inner tub 3 are sprayed with a heavy load.
As shown in fig. 6, the circulation motor is adjusted to the second rotation speed, the plurality of nozzles 12 provide a second lift for the washing water, so that the washing water is sprayed into the middle of the inner tub 3 to form an annular water curtain, and the clothes at the middle position in the inner tub 3 are sprayed in a focused manner.
As shown in fig. 7, the circulation motor is adjusted to the third rotation speed, the plurality of nozzles 12 provide a third lift for the washing water, so that the washing water is sprayed into the rear portion of the inner tub 3 to form an annular water curtain, and the clothes at the rear portion of the inner tub 3 are sprayed with a heavy load.
As shown in fig. 8, the circulation motor is adjusted to the fourth rotation speed gear, and the plurality of nozzles 12 provide the fourth lift for the washing water so that the washing water is sprayed into the bottom of the inner tub 3. The washing water is reflected to the clothes through the inner bottom of the inner drum 3, and the impact force to the clothes is increased.
As shown in fig. 9, the circulation motor is adjusted to the fifth rotation speed stage, the plurality of nozzles 12 provide the fifth lift for the washing water such that the washing water is sprayed into the bottom of the tub 3, and the washing water sprayed from each nozzle 12 can be overlapped with each other at the rear of the tub 3. The washing water can not only be reflected to the clothes through the inner bottom of the inner drum 3, but also can make the superposed washing water directly fall onto the clothes at the rear position in the inner drum 3 after impacting each other.
As shown in fig. 10, the circulation motor is adjusted to a sixth rotation speed gear, the plurality of nozzles 12 provide a sixth lift for the washing water such that the washing water is sprayed into the bottom of the tub 3, and the washing water sprayed from each nozzle 12 can be overlapped with each other at the middle of the tub 3. The washing water can not only be reflected to the clothes through the inner bottom of the inner drum 3, but also can make the superposed washing water directly fall onto the clothes at the middle position in the inner drum 3 after impacting each other.
In summary, in the preferred embodiment of the present invention, the drum washing machine adjusts the water discharge flow of the circulation pump 8 by adjusting the rotation speed of the circulation motor, and thus adjusts the lift of the washing water sprayed from each nozzle 12, so that the washing water falls into different positions in the inner tub 3, and the clothes in the inner tub 3 are sprayed in a targeted manner, thereby improving the spraying effect of the drum washing machine on the clothes.
In addition, those skilled in the art can also appropriately adjust the number of rotation speed gears of the circulating motor as needed. For example, the electric circulation machine is made to have three rotational speed gears, four rotational speed gears, seven rotational speed gears, and the like. When the electric circulation machine has three rotational speed gears, the three rotational speed gears may be the first rotational speed gear, the second rotational speed gear, and the third rotational speed gear described above.
In addition, in another possible embodiment of the present invention, one skilled in the art may omit the arrangement of the pressure equalizer 10 and make the eight nozzles 12 of fig. 11 to 13 spray washing water in unequal amounts, as required. And meanwhile, a first rotating speed gear, a second rotating speed gear and a third rotating speed gear are configured for the circulating motor from low to high in sequence.
As shown in fig. 11, when the circulation motor is in the first rotation speed gear, only the lower three nozzles 12 among the eight nozzles 12 spray the washing water, and the upper three nozzles 12 and the middle two nozzles 12 are not capable of spraying the washing water due to insufficient water pressure.
As shown in fig. 12, when the circulation motor is in the second rotation speed gear, only the lower three nozzles 12 and the middle two nozzles 12 among the eight nozzles 12 spray the washing water, and the upper three nozzles 12 cannot spray the washing water due to insufficient water pressure.
