Description

Technical Field

[0001] This utility model relates to the field of steam oven cooking machine technology, and in particular to a cleaning mechanism, door assembly, and steam oven cooking machine. Background Technology

[0002] Steam ovens are gaining popularity due to their safety, good cooking results, and rich functionality. Existing steam ovens typically feature glass doors for users to easily observe the food's progress. However, during cooking, especially in steam mode, a large amount of moisture accumulates inside the oven cavity, easily condensing on the glass door and obstructing the view. This is particularly problematic when steam levels are high; the steam can even condense into water droplets that fall back down, further interfering with visibility and potentially leading to misjudgments of the food's cooking status, thus negatively impacting the user's cooking experience. Utility Model Content

[0003] Given that existing steam ovens are prone to condensation and water droplets forming on the door glass during steam mode, it is necessary to provide a cleaning mechanism, door assembly, and steam oven.

[0004] A cleaning mechanism for a door assembly of a steam oven, comprising:

[0005] A frame component having a window corresponding to a visible area on the door component;

[0006] A wiping element, mounted on the frame member and located above the window, the wiping element abutting against the door glass body of the door assembly; and

[0007] A drive assembly, connected to the frame member, is used to drive the frame member to move relative to the door assembly, thereby causing the wiping component to wipe away the water mist located in the visible area.

[0008] With this configuration, the wiper unit, positioned above the frame, can block water droplets flowing down from above the frame, preventing watermarks from interfering with the user's view. Because the frame has a window, it does not obstruct the user's view when it is within the visible area of ​​the door assembly, thus improving the user experience.

[0009] In one embodiment, the erasing element is detachably mounted to the frame member.

[0010] This design makes it convenient for users to replace and clean the parts, and prevents the wipes from being damp for a long time and developing odors.

[0011] In one embodiment, the outer peripheral wall of the frame member is provided with a mounting groove, and the erasing member is interference-fitted into the mounting groove.

[0012] This design makes the joint between the eraser and the frame more secure, resulting in higher reliability after assembly.

[0013] In one embodiment, the wiping component includes a rigid mounting portion installed in the mounting groove and a flexible absorbent portion fixedly connected to the rigid mounting portion.

[0014] This design facilitates the disassembly and assembly of the wiping component, while also protecting the flexible absorbent part from tearing during the process.

[0015] In one embodiment, the drive assembly includes a transmission rod fixedly connected to the frame member and a drive member driving the transmission rod.

[0016] This configuration, which uses a transmission rod to transmit the drive component, facilitates the placement of the drive component and allows it to be positioned outside the door glass. This prevents the drive component from being damaged by prolonged exposure to an overheated and humid environment, thus protecting it.

[0017] In one embodiment, the transmission rod is a rack, and the driving component includes a drive gear, a drive motor connected to the drive gear, and a conversion component located between the drive gear and the rack;

[0018] The conversion component includes a mounting bracket and a conversion gear rotatably mounted on the mounting bracket, the conversion gear meshing with the drive gear and the rack.

[0019] This design, with the introduction of a conversion gear, further enhances the flexibility of the drive motor's installation position, enabling it to better adapt to different door components and facilitating assembly.

[0020] This application also provides a gate component, including:

[0021] The main glass body of the door;

[0022] As described above, the frame of the cleaning mechanism is slidably mounted on the door glass body, the wiping component of the cleaning mechanism abuts against the door glass body, and the drive assembly of the cleaning mechanism is fixedly connected to the door glass body.

[0023] With this design, the cleaning mechanism is tightly integrated with the door glass body, making it less prone to shaking. The door assembly has a compact structure, especially the cleaning mechanism, which is smaller in thickness, reducing the overall space occupied by the door assembly.

[0024] In one embodiment, the door glass body has a visible area and an obstruction area surrounding the visible area, the shape of which matches the shape of the window of the cleaning mechanism.

[0025] This design allows the shielded area to block heat radiation while the visible area is available for the user to observe. When the user approaches to observe the cooking process of the food, the cleaning mechanism provides a good view and reduces the adverse effects of heat radiation. Furthermore, the partitioned design means that the cleaning mechanism does not need to clean the entire glass door. This allows for the use of lower-power drive components, reducing production costs. Additionally, with consistent drive component power, the wiping component in this application slides more smoothly and achieves better cleaning results.

[0026] In one embodiment, the door assembly further includes a guide rail on which the rack of the cleaning mechanism is slidably mounted.

[0027] With this configuration, the rack, frame, and wiping components slide more smoothly and are less prone to wobbling, guided by the guide rail components.

[0028] This application also provides a steam oven, comprising:

[0029] Enclosure assembly; and

[0030] As described above, the door assembly is mounted on the housing assembly, and the cleaning mechanism of the door assembly is mounted on the side of the door glass body facing the housing assembly.

[0031] This design, incorporating the cleaning mechanism into the door assembly of the steam oven, enables real-time cleaning of water mist and droplets on the door glass during cooking, improving visibility, facilitating user observation of the food's cooking status, and enhancing the user experience.

[0044] Steam ovens are gaining popularity due to their safety, good cooking results, and rich functionality. Existing steam ovens typically feature glass doors for users to easily observe the food's progress. However, during cooking, especially in steam mode, a large amount of moisture accumulates inside the oven cavity, easily condensing on the glass door and obstructing the view. This is particularly problematic when steam levels are high; the steam can even condense into water droplets that fall back down, further interfering with visibility and potentially leading to misjudgments of the food's cooking status, thus negatively impacting the user's cooking experience.

[0045] Therefore, it is necessary to provide a cleaning mechanism, door assembly, and steam oven that can wipe away water mist or droplets on the door glass during the steaming and baking process.

[0046] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the door assembly in one embodiment of the present invention. Figure 2 for Figure 1 A partial enlarged view of the middle door assembly at point X. The door assembly provided in this application includes a door glass body 50 and a cleaning mechanism. The cleaning mechanism includes a frame member 10 slidably mounted on the door glass body 50, a wiping member 20 abutting against the door glass body 50, and a drive assembly 30 fixedly connected to the door glass body 50. The door glass body 50 has a viewing area 51 and a blocking area 52 surrounding the viewing area 51. The frame member 10 has a window 101 that corresponds to and matches the shape of the viewing area 51 on the door assembly. The wiping member 20 is mounted on the frame member 10 and located above the window 101. The wiping member 20 abuts against the door glass of the steam oven. The drive assembly 30 drives the frame member 10 to move relative to the door assembly, thereby causing the wiping member 20 to wipe away the water mist in the viewing area 51 of the door glass. The wiping component 20 in this cleaning mechanism is located above the frame component 10 and can block water droplets flowing down from above the frame component 10, preventing water streaks left by the droplets from interfering with the user's view. Since the frame component 10 has a window 101, when the frame component 10 is located in the visible area 51 of the door assembly, the frame component 10 itself will not obstruct the user's view. Furthermore, the wiping component 20 only needs to wipe away water mist or droplets within the window 101. Compared to solutions that require cleaning the entire door glass assembly, the friction between the wiping component 20 and the door glass in this application is lower, and the driving force provided by the drive component 30 is also lower. Therefore, the range of drive components 30 that can be selected is wider, which helps to reduce production costs.

[0047] The cleaning mechanism provided in this application includes a two-step wiping process. The first step is that the wiping element 20 moves downward to wipe away the water mist in the visible area 51. The second step is that the wiping element 20 moves upward until it returns to its original position. The two wiping steps improve the cleaning effect on the visible area 51. It is worth noting that as cooking time increases, the water mist will gather into water droplets and adhere to the frame member 10. In particular, in the second step mentioned above, the frame member 10 carries the water droplets during the resetting process and forms watermarks on the door glass body 50. Based on this, in one embodiment provided in this application, the frame member 10 is arranged at a distance from the door glass body 50. This way, the frame member 10 will not adhere to water droplets during movement, and therefore, after the wiping element 20 completes one wiping, the frame member 10 will not carry water droplets and leave watermarks in the visible area 51. It is understood that in this embodiment provided in this application, the frame member 10 is rectangular, and the two longitudinal beams of the frame member 10 extending vertically can abut against the door glass body 50, while the two horizontal beams are arranged at intervals with the horizontal beams of the wiping member 20. Since the two longitudinal beams will not sweep across the visible area 51 during the sliding process, even if the longitudinal beams are covered with condensation, it will not affect the view of the visible area 51.

[0048] Please see Figure 2 Optionally, in one embodiment provided in this application, the wiping component 20 is detachably installed on the frame component 10. This facilitates user replacement and cleaning, and prevents the wiping component 20 from being in a damp state for a long time and generating odors. Furthermore, the outer peripheral wall of the frame component 10 is provided with a mounting groove 102, and the wiping component 20 is interference-fitted into the mounting groove 102. In this way, the connection between the wiping component 20 and the frame component 10 is more secure, and the reliability after assembly is higher. Furthermore, in order to facilitate disassembly and assembly and protect the wiping component 20 during disassembly and assembly, the wiping component 20 includes a rigid mounting part 21 installed in the mounting groove 102 and a flexible water-absorbing part 22 fixedly connected to the rigid mounting part 21. The flexible water-absorbing part 22 can be made of materials such as foam or cloth. It is understood that in other embodiments, the mounting portion of the erasing member 20 may also be snapped together with the frame member 10. In another embodiment, the mounting groove 102 and the mounting portion may also be designed as a slide rail slider. The mounting groove 102 extends through the frame member 10 along its own extension direction, and the erasing member 20 slides into the mounting groove 102 from one of its open ends.

[0049] Please see Figure 3 and Figure 4 , Figure 3 for Figure 1 The diagram shows the structural structure of the door assembly from another perspective. Figure 4 for Figure 3A partial enlarged view of the middle door assembly at point Y. Optionally, in one embodiment provided in this application, the drive assembly 30 includes a transmission rod 31 fixedly connected to the frame member 10 and a drive member 32 driven by the transmission rod 31. The drive member 32 is transmitted by the transmission rod 31, which facilitates the placement of the drive member 32 and allows the drive assembly 30 to be placed outside the door glass, avoiding damage to the drive member 32 due to long-term exposure to an overheated and humid environment, thus protecting the drive member 32. Optionally, the transmission rod 31 is a rack 311, and the driving component 32 includes a drive gear 321, a drive motor 322 connected to the drive gear 321, and a conversion component 323 located between the drive gear 321 and the rack 311. The conversion component 323 includes a mounting bracket 3231 and a conversion gear 3232 rotatably mounted on the mounting bracket 3231. The conversion gear 3232 meshes with the drive gear 321 and the rack 311. By introducing the conversion gear 3232, the flexibility of the installation position of the drive motor 322 is further improved, thereby better adapting to different door components and facilitating assembly. Specifically, the drive motor 322 and the mounting bracket 3231 are respectively fixedly connected to the lower part of the door glass body 50, which can protect the drive motor 322 and the mounting bracket 3231. The mounting bracket 3231 includes a first mounting rod 32311 spaced apart on the lower side of the door glass body 50 and two first mounting feet 32312 respectively mounted on both ends of the first mounting rod 32311. The first mounting feet 32312 are fixedly connected to the door glass. It is understood that in other embodiments, the conversion gear 3232 is slidably mounted on the first mounting rod 32311 to adapt to the actual installation position of the rack 311.

[0050] Please see Figure 3 and Figure 4Optionally, to improve the smoothness of sliding of the rack 311, frame member 10, and wiping member 20, in one embodiment of this application, the door assembly further includes a guide rail 40, on which the rack 311 of the cleaning mechanism is slidably mounted. Specifically, the guide rail 40 includes a track body 41 with vertical grooves, second mounting rods 42 spaced apart from the door glass, and two second mounting feet 43 respectively mounted at both ends of the second mounting rods 42 and mounted on the door glass body 50. The track body 41 is mounted on the second mounting rods 42. It is understood that in other embodiments, the track body 41 is slidably mounted on the second mounting rods 42. In this way, the rack 311, track body 41, and conversion gear 3232 can all be slidably adjusted relative to the door glass body 50. This facilitates adjusting the position of the visible area 51 when designing the door assembly and also avoids interference from other structures on the door assembly. Optionally, the vertical groove is oriented towards the door glass body 50, which also helps the auxiliary wiping component 20 to abut against the door glass body 50 and prevents the wiping component 20 from separating from the door glass body 50.

[0051] This application also provides a steam oven, including a housing assembly and the aforementioned door assembly. The cleaning mechanism of the door assembly is installed on the side of the door glass body 50 facing the housing assembly. Such a steam oven also has the function of cleaning the door glass body 50. When water vapor or water droplets condense on the door glass body 50 in steam mode, the cleaning function can clean the field of vision 51 on the door glass body 50 in a timely manner, making it convenient for users to observe the state of food during cooking and improving the user's cooking experience.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
