Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of steaming oven, in particular to a door assembly and steaming oven. BACKGROUND

[0002] The door handle of the existing steaming oven is mostly fixed on the outer door glass by screws, and the structure of the door handle protrudes from the outer door glass surface. If not careful, there is a risk of bumping, and even the risk of outer door glass explosion when the force is large. In order to hide the door handle in the door body, the common implementation scheme is to open a sunken groove or handle hole on the door body to accommodate the door handle, design the door handle into a plate, and then connect the door handle and the door body through a rotating shaft. Setting the rotating shaft outside the door can eliminate the gap at the handle hole, but the cost is that the outer surface of the door body is uneven. Although setting the rotating shaft inside the door can achieve a certain degree of flatness of the outer surface of the door body, the matching gap between the door handle and the door body needs to be reserved at the handle hole, which cannot realize hidden, the matching gap is easy to enter dust, resulting in high cleaning difficulty, and also blocks the rotation of the door handle. SUMMARY

[0003] Based on the problem that the door handle is easy to produce uneven outer surface or need to pre-set larger matching gap in the existing steaming oven in order to realize hidden door handle, it is necessary to provide a door assembly and steaming oven.

[0004] A door assembly, comprising:

[0005] A door body having a receiving cavity and a handle hole communicating with the receiving cavity;

[0006] A mounting seat installed in the receiving cavity and having a circular arc track, the center of the circular arc track being located outside the door body and close to one side of the handle hole;

[0007] A flip cover piece having a cover surface matching the size of the handle hole, the flip cover piece being slidably installed in the circular arc track;

[0008] When the flip cover piece slides to one end of the circular arc track, the cover surface is flush with the outer side of the door body to make the door assembly in a first state; when the flip cover piece slides to the other end of the circular arc track, the cover surface is located outside the handle hole to make the door assembly in a second state.

[0009] Thus, by designing the circular arc track in the door body to cooperate with the flip cover, the flip cover can be flipped out of the handle hole, and the center of the circular arc track is arranged outside the door body and close to one side of the handle hole, so that the flip cover does not interfere with the door body at the handle hole when switching between the two states of the door assembly. Therefore, the shape and size of the cover surface on the flip cover can be consistent with the handle hole as much as possible, thereby reducing the cooperation gap between the flip cover and the door body and reducing the risk of dust and dirt blocking the rotation of the flip cover.

[0010] In one of the embodiments, the center of the circular arc track is located at the upper edge of the handle hole.

[0011] Thus, the rotation axis of the cover plate is located at the upper edge of the handle hole, that is, the upper edge of the plate remains unchanged during the flipping process. When the door assembly is in the second state, the cover plate can block the objects falling from above to prevent the debris or water droplets from entering the door body.

[0012] In one of the embodiments, the flip cover includes a cover plate providing the cover surface and first and second sliding blocks fixedly connected to the cover plate, and the first and second sliding blocks are movably mounted on the circular arc track and arranged along the circumference of the circular arc track.

[0013] Thus, by defining the degrees of freedom of the cover plate through the two sliding blocks, the cover plate can be prevented from shaking during the switching between the two states, that is, the moving track of the cover plate is stable.

[0014] In one of the embodiments, the flip cover has a yielding annular surface located at the edge of the cover plate and gradually inwardly recessed from the outside of the handle hole.

[0015] Thus, when the cover plate is flipped, the guide slope can guide the cover plate to avoid the outer edge of the handle hole during rotation, thereby avoiding the structural interference between the cover plate and the door body, making the size of the cover plate closer to the size of the handle hole, and further reducing the gap between the cover plate and the door body.

[0016] In one of the embodiments, the mounting seat includes a first plate body provided with a mounting opening, a support ring body providing the circular arc track, and a second plate body detachably mounted on the first plate body, and the second plate body covers the support ring body.

[0017] The first and second sliding blocks are arranged through the mounting opening, the circular arc track includes first and second track groove sections corresponding to the first and second sliding blocks, respectively, and the side of the support ring body close to the second plate body is further provided with first and second notch grooves respectively communicating with the first and second track groove sections.

[0018] In this way, the arrangement of the notch slots facilitates the mounting of the two sliders of the flip cover to the two track slot segments.

[0019] In one of the embodiments, the mounting base further comprises a first positioning post and a second positioning post fixed to the second plate body and respectively inserted into the first notch slot and the second notch slot.

[0020] In this way, the second plate body and the first plate body can be pre-positioned for easy assembly, and the two circular arc tracks can be closed to prevent the two sliders from falling out of the circular arc tracks.

[0021] In one of the embodiments, the door assembly further comprises a press lock connected to the flip cover, the press lock comprising a male buckle mounted to the flip cover and a female buckle mounted to the mounting base, the insertion direction of the male buckle and the female buckle being tangent to the circumferential direction of the circular arc track.

[0022] In this way, when the door assembly is in the first state, the user can unlock the cover plate by pressing, and the cover plate is ejected in a flip manner under the pushing action of the ejecting spring and maintained at a flip angle, facilitating the user's finger to be inserted, and at the same time, the male buckle and the female buckle are locked by pressing again to make the door assembly return to the first state, thereby hiding the cover plate, which is convenient to operate.

[0023] In one of the embodiments, the door assembly further comprises an ejecting spring mounted to the mounting base, two ends of the ejecting spring respectively abutting against the flip cover and the mounting base.

[0024] In this way, when the door assembly switches from the first state to the second state, the flip cover is automatically ejected from the handle hole under the pushing action of the ejecting spring, which facilitates the user's finger to be inserted.

[0025] In one of the embodiments, the flip cover has a limiting hole, and the door assembly further comprises a circular arc guide rod fixedly connected to the mounting base, the circular arc guide rod being arranged with the circular arc track as a common center, the ejecting spring being sleeved on the circular arc guide rod, and the circular arc guide rod being movably inserted into the limiting hole.

[0026] In this way, the deformation of the ejecting spring is constrained by the circular arc guide rod, preventing the bending angle of the ejecting spring from being too large and causing the ejecting spring to fail.

[0027] The application also provides a steam oven, comprising:

[0028] a box assembly;

[0029] a door assembly as described above, the door body of the door assembly being mounted to the box assembly.

[0030] With this design, the smooth outer surface of the door assembly will prevent users from bumping into it during actual use. In particular, when the outer door panel is made of glass, the hidden door handle design of this door assembly can prevent the outer door panel from being pulled apart. Attached Figure Description

[0047] With the significant improvement of people's living standards and the continuous upgrading of consumer electronics technology functions, consumers have long been unable to satisfy the traditional functions of general kitchen electrical products, and based on their "duty" of cooking delicious food, they expect the new generation of kitchen electrical products to bring more excellent cooking effects, better use experience, faster efficiency improvement and more intelligent control methods. In this background, the steam oven emerged as the times required.

[0048] The door handle of the existing steam oven is mostly fixed on the outer door glass by screws, and the structure of the door handle protruding from the outer door glass surface. If not careful, there is a risk of knocking, and even the risk of outer door glass explosion when the force is too large. In order to hide the door handle in the door body, the common implementation scheme is to open a sunken groove or handle hole on the door body to accommodate the door handle, design the door handle into a plate, and then connect the door handle and the door body through a shaft. Setting the shaft outside the door can eliminate the gap at the handle hole, but at the cost of the uneven outer surface of the door body. Although setting the shaft inside the door can achieve the flatness of the outer surface of the door body to a certain extent, the matching gap between the door handle and the door body needs to be reserved at the handle hole, which cannot realize hidden, the matching gap is easy to enter dust, resulting in high cleaning difficulty, and also blocks the rotation of the door handle.

[0049] Therefore, it is necessary to provide a door assembly and steam oven capable of hiding the door handle and having a more flat outer surface.

[0050] Please refer to Figures 1 to 8 , Figure 1 The structure of the door assembly in an embodiment of the present application is shown in the figure, Figure 2 isFigure 1 An exploded structural schematic diagram of the door assembly, Figure 3 As Figure 2 A structural schematic diagram of the flip cover 30 and the mounting base 20 in the first state, Figure 4 As Figure 2 A structural schematic diagram of the flip cover 30 and the mounting base 20 in the second state, Figure 5 As Figure 4 A structural schematic diagram of the flip cover 30, Figure 6 As Figure 4 A structural schematic diagram of the mounting base 20, Figure 7 As Figure 6 A structural schematic diagram of the first assembly in the mounting base 20, Figure 8 As Figure 6 A structural schematic diagram of the second assembly in the mounting base 20.

[0051] The door assembly provided by the present application comprises a door body 10, a mounting base 20, and a flip cover 30. The door body 10 has a receiving cavity 101 and a handle hole 102 which is communicated with the receiving cavity 101. The mounting base 20 is mounted in the receiving cavity 101 and has a circular arc track 201. The center of the circular arc track 201 is located outside the door body 10 and close to one side of the handle hole 102. The flip cover 30 is slidably mounted in the circular arc track 201 and has a cover surface 301 which matches the size of the handle hole 102. When the flip cover 30 slides to one end of the circular arc track 201, the cover surface 301 is flush with the outer side of the door body 10 so that the door assembly is in the first state. When the flip cover 30 slides to the other end of the circular arc track 201, the cover surface 301 is located outside the handle hole 102 so that the door assembly is in the second state. The present application cooperates the circular arc track 201 with the flip cover 30 by designing the circular arc track 201 in the door body 10, so that the flip cover 30 can be flipped out of the handle hole 102. The center of the circular arc track 201 is set outside the door body 10 and close to one side of the handle hole 102, so that the flip cover 30 does not interfere with the door body 10 at the handle hole 102 when the door assembly switches between the two states. Therefore, the shape and size of the cover surface 301 on the flip cover 30 can be consistent with the handle hole 102 as much as possible, so as to reduce the fitting gap between the flip cover 30 and the door body 10 and the risk of dust and dirt blocking the rotation of the flip cover 30.

[0052] As Figure 3 and Figure 4 As shown in the preferred embodiment provided by the present application, the center of the circular arc track 201 is located at the upper edge of the handle hole 102. In this way, the rotation axis of the cover plate 31 is located at the upper edge of the handle hole 102, that is, the upper edge of the cover plate remains unchanged during the flipping process. When the door assembly is in the second state, the cover plate 31 can block the objects falling from above and prevent the objects or water droplets from entering the door body 10.

[0053] As Figure 5 and Figure 7 shown, Figure 5 is Figure 4 a structural schematic view of the flip cover 30, Figure 7 is Figure 6 a structural schematic view of the first assembly in the mounting seat 20, specifically, the flip cover 30 includes a cover plate 31 providing a cover surface 301 and a first slider 32 and a second slider 33 fixedly connected to the cover plate 31, the first slider 32 and the second slider 33 are respectively movably mounted on the circular arc track 201 and arranged along the circumference of the circular arc track 201. The freedom of the cover plate 31 is limited by the two sliders, which can prevent the cover plate 31 from shaking when switching between the two states, that is, the moving track of the cover plate 31 is stable. Optionally, the first slider 32 and the second slider 33 are respectively in a cylindrical shape, and the circular arc track 201 is a track groove, and the first slider 32 and the second slider 33 are respectively inserted into the track groove, which is conducive to improving the smoothness of the flip cover 30 sliding along the circular arc track 201. It can be understood that in other embodiments, an arc-shaped slider can also be used, which has the same curvature as the circular arc track 201. Optionally, the circular arc track 201 includes a first track segment and a second track segment arranged along the circumference, and the two track segments correspond to the first slider 32 and the second slider 33 respectively, which is to reduce the influence of the length of the opening on the mounting seat 20 on the structural strength of the mounting seat 20 itself.

[0054] As Figure 5 shown, in order to further reduce the structural interference between the cover plate 31 and the door body 10 at the handle hole 102, the flip cover 30 has a yielding ring surface 302 located at the edge of the cover plate 31 and gradually inwardly retracted from the outside of the handle hole 102. In this way, when the cover plate 31 is flipped, the guide slope can guide the cover plate 31 to avoid the outer edge of the handle hole 102 when rotating, avoiding the structural interference between the cover plate 31 and the door body 10, making the size design of the cover plate 31 closer to the size of the handle hole 102, and further reducing the gap between the cover plate 31 and the door body 10.

When the door assembly is in the first state, the user can unlock the cover plate 31 in a pressing manner, the cover plate 31 is popped up in a flip manner and maintained at a flip angle under the pushing action of the ejection spring 60, which facilitates the user's finger to stretch in, at the same time, the male buckle 41 and the female buckle 42 are locked in a pressing manner again to make the door assembly return to the first state, thereby hiding the cover plate 31. Further, in order to maintain the structural stability of the door assembly in the second state and facilitate the user to operate, the door assembly further comprises an ejection spring 60 mounted to the mounting base 20, both ends of the ejection spring 60 abutting against the flip cover 30 and the mounting base 20 respectively, in this way, when the door assembly switches from the first state to the second state, the flip cover 30 is automatically popped up from the handle hole 102 under the pushing of the ejection spring 60, which facilitates the user's finger to stretch in. When the flip angle of the cover plate 31 is large, the ejection spring 60 will be bent, which is easy to fail due to the bending angle being too large, in order to avoid this, the door assembly further comprises a circular arc guide rod 50 fixedly connected to the mounting base 20 and arranged with the circular arc track 201 at the same center, the flip cover 30 has a limiting hole 303, the ejection spring 60 is sleeved on the circular arc guide rod 50, the circular arc guide rod 50 is inserted into the limiting hole 303, specifically, the flip cover 30 further comprises an abutting ring 34 fixedly connected to the second sliding block 33, and the limiting hole 303 is provided by the abutting ring 34.
