[0042] In the related art, a microwave oven with automatic door opening realizes automatic door opening by pushing the door body to a certain angle through an electric push rod, and then the door body falls down by gravity and spring force. Moreover, during the manual door closing process, when a certain angle is reached, the door body can automatically close by the hinge spring force to improve the user experience.

[0043] The first direction in this solution is the Y direction. Figure 4 The up and down directions in the figure are as follows: Figure 4 The left and right directions in the diagram are as follows: Figure 4 The front-to-back direction.
[0044] See also Figure 1 , an embodiment of the present invention provides a household appliance 100, including a cavity 10, a door body 20, a door opening assembly 40 and a door closing assembly 30, the door body 20 is rotatably connected to the cavity 10, the cavity 10 is provided with a cavity 11, and the cavity 11 has an opening 12 on one side of the cavity 10; the door opening assembly 40 is provided in one of the cavity 10 and the door body 20, and is configured to drive the door body 20 to rotate relative to the cavity 10 to open the opening 12 when the door body 20 closes the opening 12; the door closing assembly 30 includes a magnetic part 31 and a magnetically absorbable part 32, the magnetic part 31 is provided in one of the door body 20 and the cavity 10, and the magnetically absorbable part is provided in the other of the door body 20 and the cavity 10, and the door closing assembly 30 is configured so that when the door body 20 is closed, when the angle between the door body 20 and the cavity 10 is less than or equal to a preset angle, the magnetic part 31 and the magnetically absorbable part 32 attract each other to cause the door body 20 to close the opening 12.
[0045] The above-mentioned household appliance 100 solves the current technical problem of the door body 20 not closing tightly by providing a door closing assembly 30. Specifically, a magnetic part 31 or a magnetically adsorbable part 32 is provided on the cavity 10 or the door body 20, so that the angle between the cavity 10 and the door body is less than a preset angle, so as to assist in closing the door. At the same time, after closing the door, the door body 20 and the cavity 10 can be closed tightly to avoid problems such as liquid leakage, wave leakage, and air leakage.
[0046] Specifically, the household appliance 100 includes, but is not limited to, a microwave oven, an oven, a steamer, a steamer, a microwave oven, a microwave steamer, a microwave oven, a dishwasher, a disinfection cabinet, a refrigerator, etc. The cavity 11 can be used to place items. For a cooking appliance, the cavity 11 can be a cooking cavity 11 for placing ingredients.
[0047] In one embodiment, the door opening assembly 40 is provided on the top of the cavity 10, and the door opening assembly 40 can push the door body 20 to rotate away from the cavity 10 or to rotate towards the cavity 10 to open or close the opening 12 of the cavity 10. The door closing assembly 30 is used to provide additional closing force to the cavity 10 during the process of closing the opening 12 of the cavity 10. The door closing assembly 30 includes a magnetic member 31 and a magnetic attractable member 32, and the magnetic member 31 and the magnetic attractable member 32 can be arranged in two ways: the magnetic member 31 is arranged on the door body 20, and the magnetic attractable member 32 is arranged on the cavity 10, or the magnetic member 31 is arranged on the cavity 10, and the magnetic attractable member 32 is arranged on the door body 20. The magnetic member 31 and the magnetic attractable member 32 cooperate to provide additional closing force to the cavity 10 during the process of closing the opening 12 of the cavity 10.
[0048] Due to the attraction force of the magnetic member 31 and the magnetic attractable member 32, when the included angle a between the door body 20 and the cavity 10 is less than or equal to the preset angle, the magnetic attractable member 32 and the magnetic member 31 generate an adsorption force between each other, so that the door body 20 is subjected to a force towards the cavity 10, and then the door body 20 is attracted to the cavity 10 to achieve the function of assisting in closing the door. The greater the included angle between the door body 20 and the cavity 10, the smaller the attraction force between the magnetic attractable member 32 and the magnetic member 31. The smaller the included angle between the door body 20 and the cavity 10, the greater the attraction force between the magnetic attractable member 32 and the magnetic member 31.
[0049] Please continue to refer to Figure 1 and Figure 2 In some embodiments, the preset angle is not greater than 30°. In this way, the magnetic member 31 and the magnetic attractable member 32 can better assist in closing the door body 20.
[0050] The magnetic member 31 and the magnetic attractable member 32 generate an adsorption force between each other, and the maximum angle at which the magnetic member 31 and the magnetic attractable member 32 can generate an attraction force is 30 degrees. In some examples, the preset angle can also be 0°, 5°, 10°, 15°, 20°, 25°, 30° or other angles less than 30°, which can be adaptively selected according to the attraction force of the magnetic member 31 or the magnetic attractable member 32 and the size of the cavity 10 and the door body 20.
[0051] During the process of opening the door, the included angle between the door body 20 and the cavity 10 becomes larger and larger, at this time, the attraction force brought by the magnetic member 31 continues to decrease, and when the included angle between the door body 20 and the cavity 10 is greater than the preset angle, the attraction force between the magnetic member 31 and the magnetic attractable member 32 gradually decreases, and the door body 20 can be opened by the spring in the hinge 50 and its own gravity.
[0052] During the door closing process, the angle between the door body 20 and the cavity 10 gradually decreases. When the angle between the door body 20 and the cavity 10 is less than or equal to a preset angle, the attraction between the magnetic member 31 and the magnetically absorbable member 32 gradually increases, providing a gradually increasing closing force. The attraction between the magnetic member 31 and the magnetically absorbable member 32 can help the hinge overcome the gravity of the door body 20 itself and the resistance of the hinge to assist in closing the door body 20. After the door is closed, the attraction between the magnetic member 31 and the magnetically absorbable member 32 ensures a tighter fit between the cavity 10 and the door body 20, thereby preventing problems such as liquid leakage, wave leakage, and air leakage.
[0053] See also Figure 2 and Figure 3 In some embodiments, the door body 20 includes a first direction (eg Figure 2 The first side portion 21 and the second side portion 22 are arranged in the Y direction (i.e., the up-down direction) as shown in the figure, and the door body 20 is rotatably connected to the cavity 10 via the first side portion 21, and the magnetic member 31 or the magnetically attractable member 32 is located on the second side portion 22. This makes it easier to close the door body 20.
[0054] Understandably, Figure 2 As shown, the first side portion 21 is the lower portion of the door body 20, and the second side portion 22 is the upper portion of the door body 20. The first side portion 21 can be hinged to the door body 20 through a hinge, so that the door body 20 can rotate around the cavity 10; specifically, a hinge 50 is provided on the side wall of the cavity 10 facing the first door component 23, and the first door component 23 is connected to the cavity 10 through the hinge 50; the magnetic member 31 or the magnetically adsorbable member 32 provided on the second side portion 22 can be moved along the second direction (such as Figure 4 the magnetic member 31 or the magnetically adsorbable member 32 is provided on the first side portion 21, so that the door body 20 can be closed more smoothly.
[0055] See also Figure 3 In some embodiments, the door body 20 has an inner cavity 237, and the magnetic member 31 or the magnetically absorbable member 32 is located in the inner cavity 237. In this way, the magnetic member 31 or the magnetically absorbable member 32 can be protected.
[0056] It can be understood that the inner cavity 237 formed by the door body 20 is used to install the magnetic part 31 or the magnetically adsorbable part 32, so that the inner cavity 237 can protect the magnetic part 31 or the magnetically adsorbable part 32, preventing the magnetic part 31 or the magnetically adsorbable part 32 from being exposed to the outside and easily damaged, thereby improving the service life of the magnetic part 31 or the magnetically adsorbable part 32.
[0057] Optionally, the magnetic part 31 or the magnetically adsorbable part 32 can also be arranged on the left and right sides of the second side portion 22 of the door body 20 to better seal the door body 20 and the cavity 11 on the side; the magnetic part 31 or the magnetically adsorbable part 32 can be set as one or multiple ones can be set at intervals. Similarly, in order to facilitate the installation of the magnetic part 31 or the magnetically adsorbable part 32, the inner cavity 237 is also adaptively adapted.
[0058] Optionally, the magnetically absorbable member 32 includes, but is not limited to, a magnetic member 31 or a structural member made of a material (e.g., iron) absorbable by the magnetic member 31. The magnetically absorbable member 32 may be a part of the cavity 10 or the door 20, or may be an additional part provided on the cavity 10 or the door 20. The magnetic member 31 includes, but is not limited to, a magnet, an electromagnet, etc., and is not specifically limited herein.
[0059] In one example, the magnet material is NdFeB.
[0060] In some embodiments, the door body 20 includes a first door assembly 23 and a second door assembly 24, which are connected to form an inner cavity 237. This allows the door body 20 to be modular in design, facilitating maintenance and replacement of the door body 20.

In this way, the first bracket 2311 and the second bracket 2312 can be set with different decorative colors respectively, so that there are more options for the decorative effect of the second frame 235.
[0080] See also Figure 9 and Figure 10 In some embodiments, the door opening assembly 40 includes a driver 41, a push rod 42, and a mounting member 43. The mounting member 43 is mounted on the housing 10, and the driver 41 is mounted on the mounting member 43. The mounting member 43 has a receiving cavity, and the push rod 42 is disposed within the cavity. This isolates the push rod 42, preventing interference with other components of the household appliance 100 and potential damage.
[0081] It can be understood that the door opening assembly 40 can enable the door body 20 to open the opening 12. The door opening assembly 40 includes a mounting member 43 arranged on the top of the cavity 10. The interior of the mounting member 43 has a receiving cavity, and the receiving cavity is used to install the push rod 42 to isolate the push rod 42. On the one hand, it can protect the push rod 42. On the other hand, other components are also installed on the top of the cavity 10, such as a water pump, a fan assembly, etc., and also include connecting wires and water pipes between components. The push rod 42 is partially arranged in the receiving cavity. When the push rod 42 moves, it will not be pulled by other components, or the probability of pulling other components is reduced. The driving member 41 can drive the push rod 42 to move along a third direction (such as Figure 1 When the door is opened, the driving member 41 provides power to the push rod 42 so that the push rod 42 can move in the third direction (such as the Z direction) to open the door. Figure 1 The Z direction shown in the figure makes a reciprocating motion.
[0082] The above-mentioned door opening component 40 may include a pneumatic rod, a hydraulic rod, a screw mechanism or a rack 44 mechanism that can realize reciprocating motion; optionally, the door opening component 40 may include a transmission mechanism, the transmission mechanism includes a gear and a rack 44, specifically, the driving member 41 is a motor, the gear is installed on the output shaft of the motor, the rack 44 is fixedly connected to the push rod 42, or the rack 44 is a part of the push rod 42, the gear is engaged with the rack 44, and when the motor starts, it drives the gear to rotate, and the rack 44 switches the rotational motion to translational motion, thereby causing the push rod 42 to push open the door body 20 to open the door.
[0083] In some embodiments, the door opening assembly 40 and the door closing assembly 30 are located on the same side of the central axis of the cavity 10. In this way, the door opening assembly 40 can more easily open the door body 20 and reduce deformation of the door body 20 during the opening process.
[0084] In some embodiments, the door opening assembly 40 is provided with one, and the door closing assembly 30 is provided with one or more magnetic members 31 or magnetically adsorbable members 32.
