[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] The drum washing machine involved in this embodiment includes a shell and a door assembly that can be opened and closed on the front side of the shell. The focus of this utility model is the structure of the door assembly. The specific structure of the drum washing machine is the prior art. For details, please refer to the content disclosed in Chinese utility model patent "Door Assembly and Drum Washing Machine" with patent number ZL202320922161.0 (authorization announcement number CN220013123U). It will not be described in detail in this embodiment.

[0023] like Figures 1-4 As shown, the door assembly of the drum washing machine in this embodiment includes a door frame 1 and a glass bowl 2 disposed on the door frame 1. Part of the glass bowl 2 can extend into the drum body of the drum washing machine. The glass bowl 2 is provided with a steam generator 3 and a water storage tank 4 connected to the steam generator 3. The surface of the glass bowl 2 is provided with a plurality of steam holes 21 for the steam generator 3 to emit steam to the drum body of the drum washing machine.

[0024] like Figure 3 and Figure 4 As shown, the water storage tank 4 extends vertically above the steam generator 3, as... Figure 3 As shown, in this embodiment, the bottom of the water storage tank 4 is provided with a water outlet 43 that can communicate with the inside of the steam generator 3. The water in the water storage tank 4 can automatically enter the inside of the steam generator 3 through the water outlet 43 under the action of gravity.

[0025] A mounting hole 22 is provided on the surface of the glass bowl 2, and the water tank 4 extends into the glass bowl 2 through the mounting hole 22. Figure 1 As shown, in this embodiment, the exposed surface of the water tank 4 on the glass bowl 2 is basically flush with the surface of the glass bowl 2 where the water tank 4 is located; in addition, to facilitate the user's removal of the water tank 4, a handle 41 is provided at the exposed position of the water tank 4 on the glass bowl 2 for easy removal. Of course, the water tank 4 and the glass bowl 2 are detachably connected. Figure 4 As shown, a push-pull locking device 42 is provided above the water tank 4. The push-pull locking device 42 is existing technology and will not be described in detail here. When the user pushes the push-pull locking device 42 downward, the user can take out the water tank 4. When the user pushes the push-pull locking device 42 upward, the water tank 4 will not interfere with the glass bowl, thus preventing the water tank from being taken out automatically and achieving safety protection.

[0026] like Figure 3 and Figure 4As shown, the steam generator 3 is equipped with multiple nozzles 31 for emitting steam. The nozzles 31 are positioned facing the drum of the washing machine and are connected to the steam holes 21. A multi-layer graphene heating plate is located at the bottom of the steam generator. The steam generator 3 in this embodiment is a nano-steam generator, the structure of which is existing technology and will not be described in detail here. The nano-steam particles generated by the steam generator 3 have a diameter range of 10-100 nanometers, much smaller than ordinary steam particles, making it easier to penetrate into the internal fibers of clothing, thus improving the depth and effect of sterilization and ironing. Simultaneously, the nano-steam generator requires a working temperature range of 60-90℃, lower than ordinary steam temperatures, making it safer and avoiding the safety hazards caused by excessively high ordinary steam temperatures. Furthermore, the steam conversion rate of the nano-steam generator can reach over 90%, higher than that of ordinary steam generators, resulting in higher efficiency and energy savings.

[0027] The steam generator 3 is also equipped with a baffle 32 for opening or closing the nozzle 31, and a driving component connected to the baffle 32. The baffle 32 can rotate under the drive of the driving component, thereby opening or closing the nozzle 31. Figure 4 As shown, in this embodiment, the baffle 32 is fan-shaped, and each nozzle 31 corresponds to a baffle 32. The nozzle 31 can be opened or closed by rotating the baffle 32, thereby making the nozzle 31 connected to the steam hole 21 or disconnecting the nozzle 31 from the steam hole 21. With this configuration, the glass bowl 2 is sealed when the drum washing machine is in the washing state.

[0028] The glass bowl 2 also contains a temperature detection module (not shown in the figure) for detecting the temperature inside the steam generator 3. Both the temperature detection module and the steam generator 3 are electrically connected to the controller. In this embodiment, the temperature detection module is a PTC sensor.

[0029] The working process of the steam generator in this embodiment is as follows:

[0030] When the drum washing machine is in the washing state, the baffle 32 rotates to block the nozzle 31, preventing water from entering the nozzle 31; when the drum washing machine is not in the washing state, the baffle 32 rotates to connect the nozzle 31 with the steam hole 21, thereby controlling the steam generator 3 to work. The steam generator 3 emits steam into the drum of the drum washing machine through the nozzle 31 to achieve the functions of sterilization and ironing of clothes.

[0031] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
