Referring to fig. 1 to 3, fig. 1 is a schematic view illustrating a drum assembly according to an exemplary embodiment of the present application; FIG. 2 illustrates a perspective view of a configuration of a drum assembly in an exemplary embodiment of the present application; fig. 3 illustrates a partial structural cross-sectional view of a drum assembly in an exemplary embodiment of the present application.

The drum assembly 1 includes an inner drum 10, an outer drum 11, and a heater 12. The outer cylinder 11 is fitted over the outer side of the inner cylinder 10, a washing chamber 101 is formed in the hollow portion of the inner cylinder 10, and the outer cylinder 11 includes an opening 111 and a bottom 112 provided in the axial direction. Wherein, the opening 111 is used as a clothes putting opening to put clothes into the washing cavity 101, the bottom 112 is provided with a motor 16, a motor shaft of the motor 16 is further arranged on the inner cylinder 10 in a penetrating way, and the motor shaft can drive the inner cylinder 10 to rotate in the washing process.

The heater 12 is provided in the outer tube 11 and is located between the opening 111 and the bottom 112. The space in which the heater 12 is located communicates with the space of the washing chamber 101. In one embodiment, the outer tub 11 includes an outer tub wall disposed between the opening 111 and the bottom 112 and extending in the circumferential direction, and the heater 12 is disposed between the outer tub wall and the inner tub 10. For example, the heater 12 is mounted on a wall surface of the outer cylinder wall on the side facing the inner cylinder 10. The inner tub 10 is provided with a plurality of through holes 102, and the space between the outer tub wall and the inner tub 10 communicates with the washing chamber 101 through the through holes 102, i.e., the space where the heater 12 is located is the space between the outer tub wall and the inner tub 10.

In the conventional drum washing machine, the heater 12 is generally installed at the bottom 112 of the outer tub 11, and when heat generated by the heater 12 flows from the bottom 112 to the opening 111, a flow path of the heat becomes long, so that it takes a long time to uniformly heat the water in the washing chamber 101 and reach a predetermined temperature. In the present embodiment, the heater 12 is provided at a position between the opening 111 and the bottom 112 of the outer tube 11. When the drum washing machine starts a washing process, the heat generated by the heater 12 can heat the water in the washing chamber 101 and circulate the heat in the directions of the opening 111 and the bottom 112, respectively. The flow path of heat is greatly shortened, thereby shortening the heating time of the washing water in the inner tub 10 and improving the heating efficiency of the washing water.

Of course, the heater 12 may also heat air to dry the laundry in the drum 10 by the hot air when the drum washing machine starts the drying process.

Referring to fig. 2 and 3, in one embodiment, the outer tub 11 includes a protrusion 113 protruding radially and toward a side away from the inner tub 10, the protrusion 113 is formed with a cavity 1131 at a side facing the inner tub 10, and the heater 12 is disposed in the cavity 1131 of the protrusion 113, and the cavity 1131 communicates with the washing chamber 101. In one embodiment, the protrusion 113 is provided at the outer cylinder wall and protrudes in a radial direction and in a direction away from the inner cylinder 10, and the cavity 1131 in the protrusion 113 communicates with the washing chamber 101 through a space between the outer cylinder wall and the inner cylinder 10. In this embodiment, the protruding portion 113 and the outer cylinder wall may be separately processed and then fixedly connected, for example, welded together. In another embodiment, the protruding portion 113 is a groove formed by extending from a part of the outer cylinder wall in the radial direction and toward a side away from the inner cylinder 10, that is, in this embodiment, the protruding portion 113 is formed as a unitary structure with the outer cylinder wall.

By providing the protruding portion 113 protruding in the radial direction of the outer tub 11 and toward the side away from the inner tub 10, the cavity 1131 of the protruding portion 113 communicates with the washing chamber 101. When the drum washing machine starts a washing process, an external water source first enters the washing chamber 101 and then flows into the cavity 1131 of the protrusion 113. After the heater 12 located in the cavity 1131 heats the water, the heated water returns to the washing chamber 101 along with the rotation of the inner cylinder 10, and flows in the directions of the opening 111 and the bottom 112, respectively, so that the water heating time is greatly shortened. Further, the protruding portion 113 protrudes in the radial direction of the outer cylinder 11 and to a side away from the inner cylinder 10, and can also provide a sufficient accommodation space for the heater 12. The gap between the heater 12 and the inner cylinder 10 after the heater is installed is too small, which is easy to damage clothes because the space between the outer cylinder wall and the inner cylinder 10 is too small.

Referring to fig. 2, in one embodiment, the protrusion 113 is disposed at a middle position between the opening 111 and the bottom 112. This minimizes the path of heat from the heater 12 to the opening 111 and the path of heat from the heater 12 to the bottom 112, thereby further improving heating efficiency.

Referring to fig. 3, in one embodiment, the protruding portion 113 is provided with a mounting opening 1132, and the heater 12 is detachably mounted in the cavity 1131 through the mounting opening 1132, so as to facilitate maintenance or replacement of the heater 12. In one embodiment, the dimension of the heater 12 in the axial direction of the outer cylinder 11 is larger than the dimension of the heater 12 in the direction perpendicular to the axial direction. Due to the smaller dimension of the heater 12 in the direction perpendicular to the axial direction, the height space of the drum assembly 1 in the direction perpendicular to the axial direction can be saved, and the drum assembly 1 is more compact in structure. In one embodiment, the heater 12 has a plate-like structure in which one side having a larger dimension extends axially along the outer cylinder 11, and the other side having a smaller dimension is located perpendicularly to the axial direction. Of course, in other embodiments, the heater 12 may also have a columnar structure, and the specific shape of the heater 12 is not limited thereto.

Referring to fig. 2 and 3, in one embodiment, the drum assembly 1 further includes a mounting portion 15 coupled to the heater 12 to facilitate mounting the heater 12 into the projection 113. In one embodiment, the mounting portion 15 is a mounting plate that includes mounting locations for mounting the heater 12 and connection locations for mating with the mounting ports 1132. When the heater 12 reaches the cavity 1131 of the protruding portion 113 through the mounting hole 1132, the mounting plate is exposed out of the protruding portion 113, is matched with the mounting hole 1132 through the connecting position, and is connected through a fastener such as a fastening screw, so that the reliability of mounting the heater 12 is improved.

With continued reference to fig. 3, in one embodiment, the roller assembly 1 further includes a sealing ring 13, the sealing ring 13 being disposed around the mounting port 1132 for sealing a gap between the heater 12 and the mounting port 1132. Therefore, after the heater 12 is mounted in the cavity 1131 of the protruding portion 113 through the mounting opening 1132, the sealing ring 13 is arranged around the mounting opening 1132, so that heat of the heater 12 can be prevented from leaking from the mounting opening 1132, and the heat utilization rate is improved. In one embodiment, when the connection position of the mounting plate is matched with the mounting port 1132, the connection position can prop against the sealing ring 13, so that the sealing ring 13 is pressed tightly, and the sealing effect is improved.

With continued reference to FIG. 2, in one embodiment, the protrusion 113 is provided with a drain 1133, the drain 1133 being in communication with the cavity 1131. Thus, after the washing process is completed, the water in the washing chamber 101 can flow into the cavity 1131 and then be discharged to the outside of the washing machine through the drain 1133. In one embodiment, the lowest point of the protrusion 113 is lower than the lowest point of the outer tub wall, and the drain 1133 is provided at the lowest point of the protrusion 113. This can improve drainage efficiency. In one embodiment, the drain 1133 is disposed on a side of the projection 113 proximate the bottom 112 of the outer barrel 11. Thereby, on the one hand, the height space of the drum assembly 1 in the direction perpendicular to the axial direction can be saved, and on the other hand, when the drain outlet 1133 is communicated with the drain pipe, the length of the drain pipe can be reduced, and the production cost can be reduced.

With continued reference to fig. 2, in one embodiment, the protrusion 113 is provided with a guiding surface 1134 on a side facing away from the inner cylinder 10, one end of the guiding surface 1134 is connected with the outer cylinder wall, and the other end extends obliquely to the lowest point of the protrusion 113, so as to guide water in the drum assembly 1 to the lowest point for being discharged from the water outlet 1133. In one embodiment, the drum assembly 1 further includes a water guiding groove (not shown) provided on the outer drum wall, the water guiding groove being provided closer to the opening 111 of the outer drum 11 than the protrusion 113, and communicating with the cavity 1131. Normally, the position of the opening 111 of the outer cylinder 11 is lower than the position of the bottom 112 of the outer cylinder 11. The water in the outer cylinder 11 near the opening 111 can be guided into the cavity 1131 through the water guide groove and then discharged from the water outlet 1133, so that the sewage can not be reserved in the outer cylinder 11, and the water discharge is more thorough.

Referring to fig. 4 and 5, fig. 4 shows a partial structural cross-sectional view of an exhaust port in an exemplary embodiment of the present application; fig. 5 shows a schematic structural diagram of a filter in an exemplary embodiment of the present application.

The outer cylinder 11 further includes an exhaust port 114 for communicating with the outside and a filter 115 detachably mounted to the exhaust port 114. Thus, when the washing machine starts the drying process, the hot and humid air in the outer tub 11 is conveniently discharged to the outside, and the drying efficiency is improved. By detachably providing the filter 115 to the exhaust port 114, the substances such as lint and lint in the hot and humid air can be filtered out, thereby reducing environmental pollution. In one embodiment, the shape of the exhaust port 114 is a cylindrical structure, which can reduce friction resistance and wind resistance. Of course, the shape of the exhaust port 114 is not limited thereto.

Referring to fig. 4, in one embodiment, the outer cylinder 11 further includes a clamping portion 1141 disposed at the air outlet 114, the filter 115 is provided with a clamping engagement portion 1153 that is engaged with the clamping portion 1141, and the filter 115 is installed in the air outlet 114 by engaging the clamping portion 1141 with the clamping engagement portion 1153. In one embodiment, one of the clamping portion 1141 and the clamping mating portion 1153 is a clamping groove, and the other is a clamping head.

Referring to fig. 5, in one embodiment, the filter 115 includes a first filter 1151 and a second filter (not shown) disposed in sequence along a gas flow direction, wherein the apertures of the first filter 1151 are larger than those of the second filter. Thus, the filter 115 can perform stepwise filtration along the gas flow direction, and can perform secondary filtration on the second filter screen by using the material such as lint and lint smaller than the mesh size of the first filter screen 1151, thereby improving the filtration effect.

Of course, the number of the filter screens in the filter 115 is not limited thereto, and a plurality of filter screens may be provided in order along the gas flow direction, and the pore diameters of the respective filter screens may be reduced in order along the gas flow direction. In addition, the shape of the filter screen should be adapted to the shape of the exhaust port 114 to improve the filtering efficiency.

With continued reference to fig. 5, in one embodiment, the filter 115 further includes a mounting frame 1152, in which the first filter screen 1151 and the second filter screen are mounted, and the filter frame has a snap fit portion 1153 for facilitating assembly with the exhaust port 114.

The foregoing description of the preferred embodiments of the present utility model is not intended to limit the utility model to the precise form disclosed, and any modifications, equivalents, improvements and alternatives falling within the spirit and principles of the present utility model are intended to be included within the scope of the present utility model.
