The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0053] The following combination Figures 1 to 7 It should be understood that the following description is merely an illustrative embodiment of the present invention and does not constitute any limitation to the present invention.

[0054] Combine Figures 1 to 9 An embodiment of the present invention provides a door assembly, which includes a bracket 100, a door hook 200, a driving member 300, a door body 800 and a voice module 810.

[0055] The bracket 100 is fixed to the steam oven body 900 .

[0056] The door hook 200 is hinged to the bracket 100 .

[0057] The driver 300 is drivably connected to the door hook 200, driving the door hook 200 to rotate at a constant speed along its hinged connection with the bracket 100, thereby forming an adjustable angle between the door hook 200 and the bracket 100. When the angle between the door hook 200 and the bracket 100 needs to be adjusted, the driver 300 drives the door hook 200 to rotate at a constant speed in the forward direction to increase the angle, and rotates it in the reverse direction to decrease the angle.

[0058] Door body 800 is fixed to door hook 200, and is hingedly connected to oven body 900 by means of door hook 200 and bracket 100 fixed to oven body 900. Driving member 300 drives door hook 200 to rotate forward at a constant speed, increasing the included angle and causing oven door 800 to open at a constant speed. Reverse rotation decreases the included angle and causes oven door 800 to close at a constant speed.

[0059] The voice module 810 is provided on the door body 800 or the oven body 900 and can emit a warning sound. For example, if the voice module 810 is provided on the oven body 900, when the door body 800 is opening or closing, the voice module 810 can detect the opening or closing of the door body 800 and emit a "beep" warning sound to alert the user and prevent hand injuries.

[0060] It can be understood that the door assembly provided by the embodiment of the present invention hinges the door hook 200 to the bracket 100 and provides a driving member 300 to drive the door hook 200 to rotate at a uniform speed around the hinge between it and the bracket 100, so that the angle between the door hook 200 and the bracket 100 can be adjusted at a uniform speed; the door body 800 is fixed to the door hook 200, and when the door hook 200 rotates at a uniform speed around the hinge between it and the bracket 100, the door body 800 and the steam oven body 900 can also be opened and closed at a uniform speed, making the door opening and closing operation easier, and after closing the door, it will not cause the steam oven to have poor sealing and water or air leakage and improve the sealing, and the door opening and closing speed is easier to control to avoid the risk of hitting people; the door assembly is also provided with a voice module 810, so that the door body 800 can emit a warning sound during the opening and closing process to remind users to pay attention to safety and prevent hands from being pinched.

[0061] Specifically, in order to make the transmission between the driving member 300 and the door hook 200 smoother and the transmission ratio more accurate, so as to further improve the opening and closing accuracy between the door body 800 and the oven body 900, in some embodiments of the present invention, the door assembly further includes a driving gear 400, a transmission gear 500 and a driven gear 600.

[0062] The transmission gear 500 is connected between the driving gear 400 and the driven gear 600. The driven gear 600 is arranged on the door hook 200. The driving member 300 drives the driving gear 400 to rotate, so that the transmission gear 500 rotates, and then the driven gear 600 rotates, so as to transmit the rotational power output by the driving member 300 to the door hook 200, so that the door hook 200 can rotate around the hinge between it and the bracket 100, thereby realizing the adjustment of the angle between the door hook 200 and the bracket 100, so that the door body 800 can be opened and closed with the steam oven body 900.

[0063] For example, the driving member 300 can be a driving motor, the driving gear 400 can be mounted and fixed on the output shaft of the driving motor, the transmission gear 500 is rotatably connected to the bracket 100 and is arranged between the driving gear 400 and the driven gear 600, the driving gear 400 and the driven gear 600 are both meshed and connected to the transmission gear 500, and the driven gear 600 can be fixed on the door hook 200 or corresponding teeth can be directly set on the door hook 200.

[0064] Combine Figure 6 In addition, in order to adapt to different lengths of the bracket 100, two transmission gears 500 can be provided between the driving gear 400 and the driven gear 600. In some embodiments of the present invention, the transmission gear 500 includes a first transmission gear 510 and a second transmission gear 520.

[0065] The first transmission gear 510 is meshed with the second transmission gear 520 for transmission connection. The first transmission gear 510 and the second transmission gear 520 may be planetary gears.

[0066] Furthermore, in some embodiments of the present invention, the door assembly further includes a damper 700 , and the damper 700 is disposed on the bracket 100 .

[0067] The first end of the damper 700 is hinged to the door hook 200, and the second end of the damper 700 abuts the bracket 100. The damper 700 can be extended and retracted in multiple stages. When the driving member 300 malfunctions, the damper 700 can generate a reaction force to prevent the door hook 200 from rapidly falling under a load (for example, the weight of the oven door 800) and causing personal injury, thereby improving the safety of the hinge assembly.

[0068] Of course, in order to avoid the angle between the bracket 100 and the door hook 200 being adjusted too large, which would cause the oven door body 800 to open and close at an excessively large angle, in some embodiments of the present invention, the bracket 100 is provided with a stop groove 110, which can limit the size of the angle between the door hook 200 and the bracket 100.

[0069] For example, a notch, namely a stop groove 110, is provided on the side of the bracket 100 facing the door hook 200 so that when the angle between the door hook 200 and the bracket 100 is reduced, the angle can only be 90°, so that the door hook 200 can only rotate in the range of 0° to 90°.

[0070] In addition, in some embodiments of the present invention, the output shaft of the driving member 300 is provided with a rib 310, and the driving gear 400 is provided with a groove 410, which matches the rib 310. When the driving member 300 drives the driving gear 400 to rotate, there will be no slipping, thereby ensuring the stability of the transmission.

[0071] Combine Figure 1 、 Figure 2 、 Figure 8 and Figure 9 An embodiment of the present invention further provides a steam oven, comprising the aforementioned door assembly and a steam oven body 900. The door assembly is hingedly connected to the steam oven body 900. When the angle between the door assembly's bracket 100 and the door hook 200 increases, the door body 800 separates from the steam oven body 900 and opens, completing the door opening. When the angle between the door assembly's bracket 100 and the door hook 200 decreases, the door body 800 closes toward the steam oven body 900, gradually closing with the steam oven body 900 to complete the door closing.

[0072] It is understood that the steam oven provided by the embodiment of the present invention, since it includes the aforementioned door assembly, necessarily possesses all the advantages of the door assembly. Specifically, the steam oven hinges the door hook 200 of the door assembly to the bracket 100 and provides a driving member 300 to drive the door hook 200 to rotate at a constant speed about its hinge with the bracket 100, thereby enabling the angle between the door hook 200 and the bracket 100 to be adjusted at a constant speed. When the door assembly is installed in the steam oven, the door body 800 of the steam oven can also be opened and closed at a constant speed, making the door opening and closing operation easier. After closing the door, the steam oven will not suffer from poor sealing, water leakage, or air leakage, and the sealing performance will be improved. Moreover, the door opening and closing speed is easier to control, thereby avoiding the risk of injury. The steam oven is also provided with a voice module 810, which enables the door body 800 to emit a warning sound during the opening and closing process to remind users to pay attention to safety and prevent pinching injuries.

[0073] Combine Figure 1 Furthermore, in order to prevent people's hands from being pinched when opening and closing the door and to improve the intelligence and safety of the steam oven, in some embodiments of the present invention, the steam oven also includes a sensing component 910. The sensing component 910 can be set on the door assembly or the steam oven body 900 and can identify objects located between the door assembly and the steam oven body 900.

[0074] For example, the sensing element 910 can be an infrared sensing probe. When a human hand is positioned between the door and the steam oven body 900, the infrared sensing probe can detect the presence of the human hand to remind the user to pay attention to safety, avoid pinching the hand, improve the user experience, and prevent the human hand from reaching into the steam oven and causing burns; at the same time, it can also improve the product quality of the steam oven, without the need for manual operation, and enhance its sense of technology.

[0075] In addition, in some embodiments of the present invention, the steam oven further includes a magnetic member 920, which can be disposed on the door assembly or the steam oven body 900 and can be attracted to and locked between the door assembly and the steam oven body 900. When the door assembly and the steam oven body 900 are closed, the magnetic member 920 can attract the door assembly, improving the sealing effect and preventing water or air leakage.

[0076] Combine Figure 8 and Figure 9 Of course, the steam oven can also be equipped with a door control lock 930 on the steam oven body 900 and a lock buckle 940 on the door body 800. After closing the door, the door control lock 930 locks the shaft into the lock buckle 940 to achieve the purpose of locking the door, preventing the door from being opened manually and accidentally falling off, and also preventing water leakage and air leakage.

[0077] The control method of the steam oven is as follows:

[0078] When the switch button is touched, the steam oven system receives the door closing command.

[0079] The driving member 300 starts to work, causing the door body 800 to close automatically and uniformly throughout the entire process.

[0080] During the process of automatically closing the door at a constant speed, the system will emit a "beep" warning sound through the voice module 810 to remind the user to be careful of pinching his hands.

[0081] After the automatic door closing is completed, the shaft of the door control lock 930 is locked into the lock buckle 940, so that the door body 800 is more sealed and prevents air leakage.

[0082] When the door is opened, the system of the steam oven receives the door opening command, the door control lock 930 pops out from the lock catch 940, and the door body 800 starts to open at a uniform speed.

[0083] In this specification, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it can mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature.
