Their functions have expanded beyond traditional bread baking to include steaming, defrosting, and grilling, significantly enhancing the user's cooking experience.

[0003] However, most steam ovens on the market still rely on manual door opening. For example, the integrated concealed door handle oven structure disclosed in Chinese patent CN220529819U, while solving the problem of protruding handles by making them concealed, still requires users to manually pull the handle to open the door. Since the oven's internal temperature is often very high after use, the heat dissipates rapidly when the door is opened, posing a significant risk of burns. Furthermore, the door opening and closing process can easily result in hands being pinched or other parts of the door being touched, creating safety hazards and causing considerable inconvenience.

[0004] Therefore, it is necessary to improve upon existing technology to provide a steam oven that can automatically open the door without causing fingers to be pinched by the door. Utility Model Content

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] refer to Figure 1-4 This utility model provides an automatic door-opening anti-pinch steam oven, including a cabinet 1, a door 2, a hinge assembly 3, a driver 4 (such as a motor, which mainly provides power for opening or closing the door 2), and a control assembly. The hinge assembly 3 is located on both sides of the cabinet 1, and the door 2 is movably connected to the cabinet 1 through the hinge assembly 3. Specifically, the cabinet 1 and the door 2 are hinged together through the hinge assembly 3. The output end of the driver 4 is connected to the hinge assembly 3, and the driver 4 can drive the door 2 to rotate through the hinge assembly 3, that is, drive the door 2 to rotate relative to the cabinet 1. When the door 2 rotates, the cabinet 1 can be closed or opened. Specifically, the cabinet 1 is provided with a cavity for holding food, and the cavity can be closed or opened when the door 2 rotates. The control assembly includes a sensor 5 and a main controller (control circuit board). The sensor 5 is located on the top of the door 2, and the main controller is located on the cabinet 1. One end of the main controller is electrically connected to the sensor 5, and the other end of the main controller is electrically connected to the driver 4.

[0026] The automatic door-opening anti-pinch steam oven provided by this utility model has the following working principle:

[0027] When the driver 4 is working, it drives the hinge assembly 3 to rotate. One end of the hinge assembly 3 is fixed to the door 2. Therefore, when the hinge assembly 3 rotates, it also drives the door 2 to rotate up and down (i.e., Figure 1 The door 2 rotates upwards (up and down) to open and close the cabinet 1, achieving automatic opening / closing of the door 2 without manual touch. Furthermore, a sensor 5 is installed on the top of the door 2. If a user's hand touches the sensor 5 during automatic opening or closing, the sensor 5 transmits a signal to the main controller. Upon receiving this signal, the main controller stops the actuator 4, thus preventing the door 2 from pinching the hand during closing. Once the sensor 5 detects the hand has moved away from the door 2, it transmits the signal back to the main controller, which then controls the actuator 4 to continue operating.

[0028] The automatic door-opening anti-pinch steam oven provided by this utility model has the following advantages compared with the prior art:

[0029] On the one hand, by setting the drive 4 and hinge assembly 3 to drive the automatic opening and closing of the oven door 2, the user can open or close the oven without touching the oven door 2 during use, avoiding the possibility of burns to the user's hands due to the high temperature of the oven door 2, and reducing certain safety hazards; on the other hand, by setting the sensor 5 on the oven door 2, once it is detected that the user's hand is inserted into the oven body 1 during the closing process of the oven door 2, the main controller will control the drive 4 to stop operating, so as to prevent the hand from being pinched during the closing process, which is safer and also further improves the user experience.

[0030] refer to Figure 2 and 3 In a preferred embodiment, the hinge assembly 3 includes a mounting base 30 and a transmission component. A driver 4 is located on one side of the mounting base 30. One end of the driver 4 extends into the mounting base 30 and connects to one end of the transmission component. The other end of the transmission component is fixed to the door 2. The driver 4 can drive the door 2 to rotate relative to the housing 1 via the transmission component. In this embodiment, the mounting base 30 is fixed to both sides of the housing 1 and is mainly used for mounting and fixing the transmission component. The output shaft of the driver 4 extends into the mounting base 30 and connects to the transmission component, thereby driving the rotation of the transmission component.

[0031] refer to Figure 2 and 3 In a further preferred embodiment, the transmission components include a first gear 31, a second gear 32, and a door hook 33. A mounting groove 301 is provided within the mounting base 30, extending along the length of the mounting base 30. Both the first gear 31 and the second gear 32 are located within the mounting groove 301. The output end of the driver 4 is connected to the first gear 31, and the first gear 31 and the second gear 32 mesh with each other. The transmission between multiple gears allows the door 2 to open and close at a more uniform speed. The door hook 33 is movably connected to one end of the mounting base 30 via a rotating shaft (movable shaft). A toothed portion 330 is provided on the side of the door hook 33 closest to the second gear 32, and the toothed portion 330 meshes with the second gear 32. When the driver 4 rotates, it transmits power to the gears, and through the meshing action between the second gear 32 and the toothed portion 330 of the door hook 33, it drives the door hook 33 to rotate. The forward or reverse rotation of the driver 4 correspondingly drives the door hook 33 to move upward or downward, thereby opening or closing the door 2. In this embodiment, the number of gears can be set according to actual needs, and is not limited to the first gear 31 and the second gear 32. That is, there can be more gears, so as to achieve the effect of deceleration and slowing down.

[0032] refer to Figure 2 and 3In a preferred embodiment, the mounting base 30 is provided with a limiting platform 302, and the door hook 33 is provided with a limiting part 331. The limiting part 331 is located above the toothed part 330. When the cabinet door 2 closes the cabinet 1, the limiting part 331 can abut against the limiting platform 302. Through the mutual cooperation between the limiting part 331 and the limiting platform 302, the door hook 33 is controlled to rotate only within the angle range of 0°-90° during operation, thereby achieving a better limiting effect.

[0033] refer to Figure 4 In a preferred embodiment, a fixing plate 20 is provided on the inner side of the door 2 (the inner side refers to the side closer to the box body 1, while the outer side is the side away from the box body 1 or facing the user). The fixing plate 20 has a first positioning hole 201, and the door hook 33 has a second positioning hole 332 that matches and connects to the first positioning hole 201. The door 2 and the door hook 33 can be fixed together through the first positioning hole 201 and the second positioning hole 332. There are multiple first positioning holes 201, spaced apart along the length of the fixing plate 20. Similarly, there are multiple second positioning holes 332, spaced apart along the length of the door hook 33. In this embodiment, the first positioning hole 201 and the second positioning hole 332 can be locked together with bolts or other locking devices for easy assembly and disassembly. Furthermore, after the door 2 and the door hook 33 are fixed together, the door 2 can move together when the door hook 33 rotates.

The hinge assembly 3 includes a mounting base 30, and the two ends of the damper 6 are fixed to the mounting base 30 and the housing 1, respectively. In this embodiment, the damper 6 can be a multi-segment telescopic structure. By setting the damper 6, a buffering effect can be achieved, and the descent of the housing door 2 can achieve a uniform speed when the door 2 is opened. On the other hand, if the actuator 4 malfunctions or is damaged, the reaction force of the damper 6 can be used to prevent the door hook 33 from falling rapidly under load and causing injury to the user.

[0035] refer to Figure 1 and 4 In a preferred embodiment, sensor 5 is a resistance sensor 5. The resistance sensor 5 has a preset sensing force range (this resistance range is generally around 1-3N). When a user's hand touches the resistance sensor 5 on the door 2, a certain resistance is generated. After detecting the relevant resistance signal, the resistance sensor 5 transmits it to the main controller, which then controls the actuator 4 to stop operating, thereby preventing injury to the user's hand. In another embodiment, sensor 5 can also be an infrared sensor 5, whose working principle is similar to that of the resistance sensor 5, and will not be elaborated here.

[0036] In a preferred embodiment, a magnetic element (not shown) is provided on the inner side of the door 2, and a metal element (not shown) (or a magnetic element) is provided on the body 1.
