Detailed Description
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 and 2, fig. 2 is an enlarged view of a portion a in fig. 1. The drum washing machine of the present invention further comprises a spraying system, which mainly comprises a circulating pump 8, a water outlet pipe 9 and an annular groove 22 arranged at the front end 21 of the outer drum. The sealing window gasket 5 has a shielding portion 51, the shielding portion 51 and the annular groove 22 form the annular water channel 10 (i.e., the shielding portion 51 covers an opening of the annular groove 22 to form a closed annular water channel 10), and the shielding portion 51 is provided with a spray opening 511. The circulation pump 8 is preferably arranged within the tank 1 and is 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. In the operation of the shower system of the present invention, as shown by the arrow in fig. 1, the circulation pump 8 pumps the washing water in the outer tub 2 to the circular water passage 10, and the washing water introduced into the circular water passage 10 is injected into the inner tub 3 through the injection port 511. When the inner tub 3 is operated at a high speed, the water stream sprayed from the spray port 511 can rapidly pass through the laundry and enter the outer tub 2 by centrifugal force and gravity.
As an example, the annular groove 22 and the water outlet pipe 9 of the present invention may be communicated through a connection structure (such as a connection hose, a connection hard pipe, etc.), or may be directly communicated (i.e., the water outlet pipe 9 is directly communicated with the annular groove 22 without the aid of a connection structure), or the annular groove 22 and the water outlet pipe 9 may be integrally formed. Those skilled in the art can flexibly select a suitable connection mode according to actual design requirements so that the circulating pump 8 can pump the washing water into the annular groove 22 through the water outlet pipe 9.
With continued reference to fig. 2, the ejection port 511 is a narrow slit structure on the shielding portion 51. Since the annular water channel 10 is formed by the shielding part 51 and the annular groove 22, and the injection port 511 of the annular water channel 10 is a narrow slit structure on the shielding part 51, a person skilled in the art can arrange a plurality of narrow slit structures on the shielding part 51 at equal intervals or at unequal intervals according to actual design requirements; or, an annular narrow slit structure (that is, a narrow slit structure which is communicated end to end is formed along the circumference of the shielding portion 51) may be further provided, so that an annular water curtain spraying effect can be realized.
As an example, the injection port 511 has a guide structure (e.g., the injection port 511 is provided in an inclined plane shape) for obliquely injecting the washing water entering the circular water passage 10 into the inner tub 3. In addition, the injection port 511 may further have an injection assembly for injecting the washing water entering the circular water passage 10 into the inner tub 3 after forming a uniform circular water curtain. It is easily understood by those skilled in the art that the spray assembly can be reasonably designed according to the shape and size of the spray opening 511, and is intended to form a uniform annular water curtain of the washing water entering the annular water passage 10 and then spray the washing water into the inner tub 3.
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 present invention forms the annular water channel 10 by the shielding part 51 of the sealing window gasket 5 and the annular groove 22 of the front end 21 of the outer tub, and the spraying port 511 is directly formed on the shielding part 51, so that the structure is simple, the structural change of the existing drum washing machine is small, and a separate spraying device is not required, thereby greatly reducing the manufacturing cost of the washing machine. In addition, as a preferred example, the spraying opening 511 of the present invention realizes the spraying effect of the circular waterfall water flow by providing the guide structure or the spraying assembly, and the spraying effect can rapidly penetrate through the laundry, thereby greatly improving the rinsing rate.
In addition, the invention also provides a drum washing machine, which comprises a washing machine body and the spraying system for the drum washing machine. For the specific embodiment of the drum washing machine, reference is made to the above description, which is not repeated herein.
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.
