Detailed Description

The present invention will be described in further detail below with reference to specific embodiments and with reference to the attached drawings.

As shown in fig. 1 and 2, an embodiment of the present application provides a washing machine, which may be a drum washing machine, and may specifically include a housing (not shown in the drawings), a window glass (not shown in the drawings), a window pad (not shown in the drawings), a tub 200, a tub 400, a front flange 500, and a drying device 600, wherein:

the inside of the housing is provided with an installation space for installing a window mat, the outer tub 200, the inner tub 400, the front flange 500, the drying device 600 and other components;

the window gasket is generally disposed between the window glass and the inner tub 400, and is used to achieve sealing between the window glass and the inner tub 400 and prevent water in the inner tub 400 from flowing out when the washing machine is operated;

the inner tub 400 is disposed inside the outer tub 200, and is used for containing the laundry and water for washing the laundry, the inner tub 400 is a generally cylindrical tub, the inner tub 400 may specifically include a front circumferential portion 410, the front circumferential portion 410 refers to a side of the inner tub 400 closer to the window pad, and the front circumferential portion 410 is provided with a second vent hole 411;

the front flange 500 includes a front end plate 510 and a stretching plate 520 connected to each other, the front end plate 510 may be a circular ring structure, the stretching plate 520 may be a circular cone structure, the inner cylinder 400 is connected to the front end plate 510, specifically, the front peripheral portion 410 of the inner cylinder 400 is connected to the front end plate 510, and the front flange 500 is located between the inner cylinder 400 and the window pad, that is, the window pad may be provided with a third ventilation hole 511 on the front end plate 510 by connecting the front flange 500 to the inner cylinder 400;

the drying device 600 may include a drying part 610 and an air outlet pipe 620, the drying part 610 is used for generating high-temperature gas, and the air outlet pipe 620 is used for sending out the high-temperature gas generated by the drying part 610; the outlet pipe 620 is connected to the outer tub 200, and the outlet pipe 620 is communicated with the inner space of the inner tub 400 through the third vent hole 511, that is, the outlet pipe 620 may extend into the outer tub 200, and the high temperature gas in the outlet pipe 620 may be sent into the inner space of the inner tub 400 through the third vent hole 511.

When the washing machine is adopted, the whole drying device 600 basically extends to the position above the front flange 500 without further extending to the position of the window gasket, so that the drying device 600 is not connected with the window gasket, the depth of the window gasket can be reduced (the direction of the depth is the axial direction of the inner barrel 400), and the depth size of the whole washing machine is reduced. Therefore, the space occupied by the washing machine is reduced.

Further, the front end plate 510 may include a first end plate 512 and a second end plate 513, the first end plate 512 and the second end plate 513 are connected, and a connection position of the first end plate 512 and the second end plate 513 is recessed toward the window mat, and third ventilation holes 511 are respectively formed in the first end plate 512 and the second end plate 513, so that the air guiding effect of the front end plate 510 is better.

Alternatively, the first ventilation hole 521 may be provided on the tension plate 520 of the front flange 500. After the first ventilation hole 521 is added, the high-temperature gas output from the drying apparatus 600 can enter the inside of the inner tub 400 through the first ventilation hole 521 and the third ventilation hole 511 at the same time, thereby better drying the laundry.

Of course, the second ventilation hole 411 may be provided in the front circumferential portion 410, and the outlet duct 620 may communicate with the internal space of the inner tube 400 through the second ventilation hole 411. At this time, the high temperature gas output from the drying device 600 may enter the inside of the inner tub 400 through the second and third ventilation holes 411 and 511 at the same time, or through the first, second and third ventilation holes 521, 411 and 511, thereby better drying the laundry.

In order to facilitate the high-temperature air output from the drying device 600 to enter the inner tub 400, an air guide surface may be provided on the outer tub 200, which is recessed toward the window mat and faces both the air outlet 621 and the third air passing hole 511 of the air outlet duct 620. At this time, the high-temperature gas output from the air outlet pipe 620 of the drying device 600 is ejected from the air outlet 621 of the air outlet pipe 620, and the ejected high-temperature gas reaches the air guide surface and is limited by the air guide surface, so that the flow direction of the high-temperature gas changes under the action of the air guide surface, specifically, the high-temperature gas points to the direction of the third air vent 511, and then enters the inside of the inner cylinder 400 through the third air vent 511.

The wind guide surface can be a cambered surface or a surface with other shapes. In one embodiment, as shown in fig. 3, the outer tub 200 may include a wind guide plate 210, and the wind guide plate 210 specifically includes a first plate 211 and a second plate 212, and the first plate 211 and the second plate 212 are connected, and both may be flat plates. In order to achieve the wind guiding function, a joint of the first plate 211 and the second plate 212 may be recessed in a direction close to the window mat, and a wind guiding surface is formed on the first plate 211 and the second plate 212. The air deflector 210 has a simple structure and can ensure an air guiding effect.

Further, the drying device 600 may further include a connection hose 630, and the air outlet pipe 620 is communicated with the tub 200 through the connection hose 630. The connection hose 630 herein is a flexible structure that can be deformed to facilitate flexible installation of the drying apparatus 600 and the tub 200. More importantly, the connection hose 630 can more efficiently convey the high-temperature gas in the drying device 600, and prevent the high-temperature gas from leaking out of the connection space between the air outlet pipe 620 and the outer tub 200, so that more gas enters the inner tub 400, thereby improving the drying effect of the clothes.

Specifically, the connection hose 630 may be a plastic pipe, and it may adopt a threaded pipe structure.

In general, the third ventilation holes 511 may be provided in plural, and in order to simplify the structure of the front end plate 510, the third ventilation holes 511 are arranged at intervals in the outer circumferential direction of the front end plate 510. The outer circumferential direction of the front end plate 510 coincides with the outer circumferential direction of the inner tube 400, and the third ventilation holes 511 may be further uniformly spaced in the outer circumferential direction of the front end plate 510. In addition, the third ventilation holes 511 may be circular holes, and the sizes of the third ventilation holes 511 may be equal, so as to further reduce the processing cost of the third ventilation holes 511.

The third ventilation holes 511 may be formed only once in the front end plate 510, and in order to increase the ventilation area, a plurality of third ventilation holes 511 may be arranged in the outer circumferential direction of the front end plate 510 to form a plurality of hole groups, and each hole group may be arranged in a group along the radial direction of the inner cylinder 400. That is, the front end plate 510 is provided with a plurality of circles of third ventilation holes 511, so that the third ventilation holes 511 are provided at each part of the front end plate 510 distributed along the radial direction of the inner cylinder 400, and the number of the third ventilation holes 511 is increased, thereby achieving the above-mentioned purpose.

The tension plate 520 may be generally configured as a tapered plate with a smaller end closer to the window mat than a larger end. At this time, the number of the first vent holes 521 in the aforementioned hole group gradually increases in a direction away from the window mat. In the aforementioned direction away from the window mat, i.e. the direction from the smaller end of the tapered plate to the larger end thereof, the cross section of the tapered plate is gradually increased, so that the number of the first ventilation holes 521 is increased, and a sufficient ventilation area can be formed at different cross sections of the tapered plate, thereby enhancing the ventilation effect.

Similarly, the front peripheral portion 410 may be generally provided as a cylindrical structure. At this time, the number of the second ventilation holes 411 in the aforementioned hole group is not changed in the direction away from the window mat. The aforementioned direction away from the window mat, that is, the axial direction of the front peripheral portion 410, in this direction, the cross-sectional area of the front peripheral portion 410 is not changed, and therefore, the number of the second ventilation holes 411 is not changed, so that the same ventilation area can be formed at different cross-sections of the front peripheral portion 410, thereby enhancing the ventilation effect.

Similarly, the front plate 510 may be generally configured as a circular ring structure. At this time, in the radial direction of the inner tube 400, the number of the third ventilation holes 511 in each hole group gradually decreases in the direction from the outside to the inside. In this direction, the area of each annular division of the front end plate 510 is gradually reduced, so that the number of the third ventilation holes 511 is gradually reduced, and thus, substantially the same ventilation area is formed at each annular division of the front end plate 510, thereby enhancing the ventilation effect.

To further improve the stability of the gas flow when the high temperature gas passes through each third ventilation hole 511, the center point of each third ventilation hole 511 in a single hole group may be located on the same plane, and the plane is perpendicular to the axis of the inner cylinder 400. After such arrangement, in the process of rotating the inner cylinder 400, the high-temperature gas output by the drying device 600 can more stably act on each third vent hole 511, and the air flow disturbance caused by the position change of each third vent hole 511 in the axial direction of the inner cylinder 400 is not easy to occur. Therefore, the high-temperature gas can enter the inner cylinder 400 more stably and smoothly by adopting the structure.

Since the drying device 600 can be disposed above the tub 200 and the outlet duct 620 extends substantially along the axial direction of the tub 200, the outlet duct 620 is generally divided into two parts, one of which is bent compared to the other to introduce the high-temperature gas inside itself into the inner tub 400. Alternatively, a portion of the end of the outlet pipe 620 may be vertical with respect to the other portion, but this causes a large resistance to the flow of the high-temperature gas inside the outlet pipe 620. Therefore, in order to reduce the resistance, a portion of the end of the outlet pipe 620 may be disposed to be inclined with respect to the radial direction of the inner cylinder 400, that is, the outlet direction of the outlet pipe 620 may be disposed to be inclined with respect to the radial direction of the inner cylinder 400. It should be noted that the air outlet direction of the air outlet pipe 620 here is also the axial direction of the air outlet 621 of the air outlet pipe 620.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
