It should be understood by those skilled in the art that the embodiments of the present invention are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. For example, although the present invention has been described with respect to an injection hole having a flat structure, the injection hole of the present invention may be an injection hole having any other structure. Those skilled in the art can make modifications as needed to suit a particular application, and such modified embodiments will still fall within the scope of the present invention.
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, 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, the front end of the box body 1 (left side of the box body 1 in fig. 1) is provided with a box body opening (not shown), the front end of the outer cylinder 2 (left side of the outer cylinder 2 in fig. 1) is provided with an outer cylinder opening (not shown), and the front end of the inner cylinder 3 (left side of the inner cylinder 3 in fig. 1) is provided with an inner cylinder opening (not shown). One end of the sealing window gasket 5 is connected with the edge of the outer cylinder opening in a sealing way, and the other end of the sealing window gasket 5 is connected with the edge of the inner cylinder opening in a sealing way. 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.
As shown in fig. 1 to 3, the drum washing machine of the present invention further includes a spray system mainly including a circulation pump 8, a water outlet pipe 9, an annular water passage 10 formed between the door body 4 and the sealing window gasket 5, and a plurality of spray holes 53 communicated with the annular water passage 10. Wherein the circulation pump 8 is preferably arranged within the tank 1 and fixedly connected to the tank 1. Alternatively, the circulation pump 8 may be fixedly connected to the outer tub 1 as required by those skilled in the art. The water inlet of the circulating pump 8 is open to the inside of the outer barrel 2, and preferably, the water inlet of the circulating pump 8 is connected with the bottom end of the outer barrel 2 through a water inlet pipe. 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 annular water channel 10 through a water outlet pipe 9. When the spraying system of the present invention is operated, as shown by arrows in fig. 1, the circulation pump 8 pumps the washing water in the outer tub 2 to the circular water passage 10, and the plurality of injection holes 53 inject the washing water into the inner tub 3 to wash the laundry. When the drum 3 is operated at a high speed, the water flow sprayed from the spray holes 53 can rapidly pass through the laundry and enter the outer tub 2 by centrifugal force and gravity.
As shown in fig. 2 and 4, a plurality of injection holes 53 are provided on the sealing gasket 5 at equal intervals around the circumferential direction of the sealing gasket 5. Alternatively, the plurality of injection holes 53 may be disposed on the sealing gasket 5 at unequal intervals as required by those skilled in the art. It will be appreciated by those skilled in the art that the annular waterway 10 may also be an arcuate waterway other than end-to-end, such as two semi-arcuate waterways, while ensuring that the plurality of injection orifices 53 are equally spaced.
As shown in fig. 1 to 3, the door 4 includes a glass observation window 41 projecting toward the outer cylinder 2.
As shown in fig. 3 to 5, the sealing window gasket 5 is provided with a water inlet 51 connected with the water outlet pipe 9 in a sealing manner. The end of the sealing window gasket 5 facing the door 4 is provided with an annular groove 52 communicating with the water inlet 51, and when the door 4 is closed (in particular the glass observation window 41), the annular groove 52 can be closed and thus the annular water channel 10 can be formed. The outlet of each spray hole 53 provided on the sealing window gasket 5 is directed to the opening of the inner tub 3 so that the water sprayed from the spray holes 53 can fall into the inner tub 3 to spray the laundry.
As shown in fig. 6, each of the spraying holes 53 is configured to spray a fan-shaped water flow or a waterfall-shaped water flow in order to improve the spraying effect of the spraying system on the clothes in the drum 3. As shown in fig. 2, 4 and 6, each of the injection holes 53 is provided in a flat structure, which is preferably a trumpet-shaped flat structure or a splayed flat structure. In other words, the injection holes 53 are provided such that the cross-section of the water outlet end thereof becomes gradually longer in the direction in which the washing water flows, while the width of the cross-section can be selectively made gradually smaller by those skilled in the art as needed.
In addition, the spray holes 53 can be formed in any other feasible shape, such as circular holes, tapered holes, or triangular shapes, as required by those skilled in the art, while ensuring that the clothes in the drum 3 can be sprayed.
Although not shown, in another embodiment of the present invention, one skilled in the art may also eliminate the annular groove 52 on the sealing gasket 5 and provide an annular groove at the end of the door body 4 facing the sealing gasket 4, as desired. When the door 4 is closed, the annular groove is closed by the sealing gasket 5 and thus forms an annular water channel 10.
It should be noted that the drain pump 6 and/or the circulation pump 8 of the present invention may be any feasible pump, such as a gear pump, a vane pump, a peristaltic pump, a centrifugal pump, etc.
It will be appreciated by those skilled in the art that in another possible embodiment of the invention, the drain pump 6 and the circulation pump 8 may be replaced by one pump. As an example one, the drain pump 6 is omitted, the water outlet of the circulation pump 8 is made to communicate with the water outlet pipe 9 and the water discharge pipe 7, respectively, and the water outlet pipe 9 is provided with a first cut-off valve for selectively opening or closing it, and the water discharge pipe 7 is provided with a second cut-off valve for selectively opening or closing it. When the drum washing machine executes the spraying operation, the first stop valve is opened, and the second stop valve is closed; when the drum washing machine performs a draining operation, the first cut-off valve is closed and the second cut-off valve is opened. As example two, the drain pump 6 is omitted and a three-way valve is provided for the water outlet of the circulation pump 8, so that the water outlet of the circulation pump 8 can be selectively communicated with the water outlet pipe 9 or the water outlet pipe 7 by means of the three-way valve. In addition, a person skilled in the art can also make the three-way valve capable of blocking the communication between the circulation pump 8 and the water outlet pipe 9 and the communication between the circulation pump 8 and the water discharge pipe 7 at the same time as required.
As described above, the circular water passage 10 of the present invention is formed between the door 4 and the sealing window gasket 5, and the injection holes 53 are formed in the sealing window gasket 5, so that the installation structure is simple and the structure of the outer cylinder 2 does not need to be modified. The production die and the manufacturing process are not separately designed for the outer cylinder 2, and the manufacturing cost of the outer cylinder 2 is reduced.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
