[0025] To better understand the door hinge assembly 100 provided in this application, the cooking equipment and the oven door will be described first.

[0026] One aspect of this application provides a cooking device, which includes an oven door as described in any of the following embodiments.

[0027] For example, the cooking device also includes a housing with a cooking cavity and a loading / unloading port formed inside the housing. The loading / unloading port is connected to the cooking cavity, and the oven door is rotatably connected to the housing to open or close the loading / unloading port.

[0028] For example, the cooking appliance may be a two-in-one or three-in-one appliance such as a microwave oven, oven, or steamer.

[0029] For example, the cooking device can be embedded.

[0030] Another aspect of this application provides a furnace door, including the door hinge plate assembly 100 in any of the following embodiments.

[0031] For example, the furnace door also includes a door body and a door / window panel, with the door body disposed on one side of the door / window panel along its thickness direction.

[0032] One embodiment of this application provides a door hinge plate assembly 100, please refer to... Figure 1 and Figure 2 The door hinge plate assembly 100 includes a door hinge plate 1 and a gasket 2. The door hinge plate 1 is disposed inside the door body, and a connecting plate 3 is disposed on the portion of the door hinge plate 1 that extends through the door body along a first direction. The connecting plate 3 is used for rotatable connection with the housing body. A portion of the gasket 2 is disposed between the connecting plate 3 and the door / window panel along the thickness direction, wherein the first direction is perpendicular to the thickness direction.

[0033] The door hinge plate assembly 100 provided in this application has a door hinge plate 1 installed inside the door body. A connecting plate 3 is provided on the portion of the door hinge plate 1 that extends through the door body in a first direction. The door body is connected to a door / window panel. Thus, the furnace door can be rotatably connected to the enclosure via the connecting plate 3, allowing it to be opened and closed. By providing a gasket 2 between the connecting plate 3 and the door / window panel, when the door hinge plate 1 with the door body is installed onto the door / window panel, the connecting plate 3 extending outside the door body can reduce the possibility of scratches caused by contact between the connecting plate 3 and the door / window panel, thereby improving the appearance and service life of the door / window panel, and even improving installation efficiency to a certain extent.

[0034] The furnace door provided in this application, based on the advantages of the aforementioned middle door shaft plate assembly 100, makes the furnace door aesthetically pleasing and extends its service life.

[0035] The cooking equipment provided in this application, based on the advantages of the aforementioned middle door hinge plate assembly 100, makes the cooking equipment aesthetically pleasing and extends its service life.

[0036] For example, the door and window panel is formed with doors and windows, and its material can be transparent materials such as glass or acrylic, so that the cooking status of the food inside the box can be seen.

[0037] For example, in one embodiment, the door body has a mounting groove, which is opened along the thickness direction towards the side opposite to the door and window panel. The mounting groove is provided through one side wall in the first direction to form a through opening, which communicates with the mounting groove. The door hinge plate 1 is disposed in the mounting groove, and the connecting plate 3 extends out of the door body through the through opening.

[0038] For example, in one embodiment, the door hinge plate 1 can be fixedly installed in the mounting groove by means of screws or pins.

[0039] For example, in one embodiment, when the door is in the closed state, the thickness direction can be the front-back direction of the cooking device, the first direction can be one of the left-right direction and the up-down direction of the cooking device, and the second direction can be the other of the left-right direction and the up-down direction of the cooking device.

[0040] It should be noted that "up" refers to the direction towards the ceiling, and "down" is the opposite of "up." The up-down, front-back, and left-right directions are perpendicular to each other, forming a three-dimensional vertical coordinate system.

[0041] In one exemplary embodiment, Figure 1 In this context, R1 can be the thickness direction, R2 can be the first direction, and R3 can be the second direction.

[0042] As an example, in one embodiment, please refer to Figure 1The cooking appliance includes a hinge plate fixed to the housing. One of the hinge plate and the connecting plate 3 has a pivot hole 3a, and the other of the hinge plate and the connecting plate 3 has a pivot shaft that rotatably engages with the pivot hole 3a. For example, the connecting plate 3 has a pivot hole 3a, and the hinge plate has a pivot shaft at its opposite end relative to the housing. The pivot shaft is inserted into the pivot hole 3a, allowing the oven door to rotate relative to the housing.

[0043] In one embodiment, please refer to Figure 1 and Figure 2 The surface of the connecting plate 3 facing the door and window panel along the thickness direction is the contact surface 3b, and the gasket 2 is set on the contact surface 3b.

[0044] In other words, gaskets 2 are provided on all surfaces of the connecting plate 3 facing the door and window panels along the thickness direction. This can further reduce the possibility of scratches when the door hinge plate 1 comes into contact with the door and window panels during installation.

[0045] In one embodiment, please refer to Figure 1 and Figure 2 The contact surface 3b includes a bent surface 3b1 and an extension surface 3b2. The connecting plate 3 includes an extension portion 31 and a bent portion 32. The extension portion 31 is connected to the door hinge plate 1. One end of the bent portion 32 is connected to the extension portion 31, and the other end of the bent portion 32 is bent. The extension portion 31 is used for rotatable connection with the housing, and the bent portion 32 is used for rotational limiting. The surface of the bent portion 32 near the door / window panel along the thickness direction is the bent surface 3b1, and the surface of the extension portion 31 along the thickness direction is the extension surface 3b2. The gasket 2 includes a first part 21 and a second part 22. The first part 21 extends along a first direction, and one end of the second part 22 is connected to the second part 22. The other end of the second part 22 is bent. The first part 21 is disposed on the extension surface 3b2, and the second part 22 is disposed on the bent surface 3b1.

[0046] For example, the other end of the extension 31 along the first direction is connected to the door hinge plate 1, and the other end of the extension 31 extends along the first direction and is connected to one end of the bent portion 32. The other end of the bent portion 32 can be bent upward or downward so that the connecting plate 3 is approximately "7" shaped. The extension 31 may have a turning hole 3a, and the bent portion 32 can be used to limit the rotation of the hinge plate to limit the rotation angle of the furnace door and reduce interference between the furnace door and the housing. The first part 21 extends along the first direction and is connected to one end of the second part 22. The other end of the second part 22 can be bent upward or downward so that the gasket 2 is approximately "7" shaped.

[0047] Here, by setting the first part 21 on the extension surface 3b2 and the second part 22 on the bending surface 3b1, on the one hand, the situation of scratches caused by the extension part 31 and the bending part 32 contacting the door and window panels can be reduced, and on the other hand, the degree of collision between the connecting plate 3 and the door and window panels during rotation can be reduced to a certain extent, thereby improving the installation efficiency of the door hinge plate assembly 100 to a certain extent.

[0048] In one embodiment, please refer to Figure 1 and Figure 2 A flange 2c is formed at the edge of the gasket 2, and the flange 2c wraps around the side of the contact surface 3b.

[0049] For example, the first part 21 can be bent along the thickness direction away from the door and window panel on one side in the second direction to form a flange 2c. This flange 2c can wrap around one side of the extended surface 3b2 along the second direction. The second part 22 can be bent along the thickness direction away from the door and window panel on one side in the first direction to form a flange 2c. This flange 2c can wrap around one side of the bent surface 3b1 along the first direction. In other words, the flange 2c makes the gasket 2 have a protective groove, and the part of the connecting plate 3 located on the contact surface 3b can be inserted into the protective groove.

[0050] In this way, by forming a flange 2c at the far end of the gasket 2, the side of the contact surface 3b can be wrapped, which further reduces the possibility of scratches caused by the contact between the connecting plate 3 and the door / window panel when installing the door hinge plate 1, making it easier for operators to install and improving installation efficiency.

[0051] In one embodiment, the gasket 2 can be connected to the connecting plate 3 by snap-fit ​​and / or adhesive bonding. This improves the connection strength between the gasket 2 and the connecting plate 3, resulting in better operational stability.

[0052] In one embodiment, please refer to Figure 1 and Figure 2 The extension 31 near the door hinge plate 1 and the bent end of the bent part 32 are both provided with positioning protrusions 3c. The first part 21 away from the second part 22 along the first direction and the bent end of the second part 22 are both provided with positioning holes 2a. The positioning protrusions 3c are inserted into the positioning holes 2a. This makes it convenient for the gasket 2 to be positioned and installed, and improves the installation efficiency.

[0053] In one embodiment, the hinge plate 1 and the connecting plate 3 can be integrally formed. This improves the connection strength between the hinge plate 1 and the connecting plate 3, resulting in better operational stability.

[0054] In one embodiment, please refer to Figure 1 and Figure 2Both the extension 31 near the door hinge plate 1 and the bent end of the bent portion 32 have notches 3d. Both the end of the first portion 21 away from the second portion 22 along the first direction and the bent end of the second portion 22 have plugs 2b. With the gasket 2 positioned on the contact surface 3b, both plugs 2b are located within their corresponding notches 3d. This not only further reduces the likelihood of scratches on the connecting plate 3 during installation when it contacts the door / window panel, but also provides a certain degree of positioning during installation.

[0055] As an example, in one embodiment, please refer to Figure 1 The end of the door hinge plate 1 near the extension 31 is bent away from the door and window panel along the thickness direction to form a folded edge 1a. The folded edge 1a and the extension 31 are spaced apart along the second direction. In this way, not only can the structural strength of the door hinge plate 1 be improved to a certain extent, but the folded edge 1a can also abut against the inner periphery of the through opening, which is convenient for positioning and installation.

[0056] In one embodiment, the door hinge plate 1 and the connecting plate 3 are made of stainless steel.

[0057] For example, the door hinge plate 1 and the connecting plate 3 can be made of SUS430.

[0058] By using stainless steel for the door hinge plate 1 and the connecting plate 3, on the one hand, the corrosion resistance of the door hinge plate 1 and the connecting plate 3 can be improved, reducing the erosion of water vapor, dust, etc., and extending their service life; on the other hand, stainless steel has a relatively small coefficient of thermal expansion, which makes its dimensional changes relatively small when the temperature changes. This can better maintain the dimensional stability of the door hinge plate 1 and the connecting plate 3, reduce the changes in the fit clearance between them and the housing caused by thermal expansion and contraction, thereby ensuring the normal opening and closing and sealing performance of the furnace door, and improving the reliability and stability of the furnace door opening and closing.

[0059] In one embodiment, the gasket 2 is made of plastic.

[0060] Here, plastic is used as the material for gasket 2. On the one hand, plastic is relatively soft, which can effectively prevent the connecting plate 3 from scratching the door and window panels. On the other hand, plastic has good chemical stability and can resist the corrosion of a variety of chemicals. Furthermore, plastic can be made into gaskets 2 of various shapes and sizes through various processing methods such as injection molding, extrusion, and compression molding to meet different design requirements.

[0061] In one embodiment, please refer to Figure 1 There are multiple door hinge plates 1, connecting plates 3 and gaskets 2. Multiple door hinge plates 1 are spaced apart along the second direction. Each door hinge plate 1 is provided with a connecting plate 3 and each connecting plate 3 is provided with a gasket 2. The first direction, the second direction and the thickness direction are perpendicular to each other.

[0062] For example, there can be two door hinge plates 1, two connecting plates 3, and two gaskets 2. The two door hinge plates 1 are an upper door hinge plate 1 and a lower door hinge plate 1, which are spaced apart on the door body along the second direction. The two connecting plates 3 are an upper connecting plate 3 and a lower connecting plate 3, and the two gaskets 2 are an upper gasket 2 and a lower gasket 2. The upper gasket 2 can be set on the upper connecting plate 3 of the upper door hinge plate 1, and the lower gasket 2 can be set on the lower connecting plate 3 of the lower door hinge plate 1.

[0063] Here, by setting multiple door hinge plates 1, connecting plates 3, and multiple gaskets 2, and spacing them along the second direction, on the one hand, the stability of the furnace door when it rotates can be improved; on the other hand, the multiple door hinge plates 1, which are spaced apart, can reduce the connecting material in the middle part compared to the integrated setting in related technologies, thereby reducing the weight of the furnace door and thus improving the problem of furnace door sagging to a certain extent, resulting in good working stability.

[0064] In one embodiment, please refer to Figure 1 The connecting plate 3 is formed with reinforcing ribs 3e.

[0065] For example, reinforcing ribs 3e can be formed on the extension 31 by stamping or pressing. This can improve the overall structural strength of the connecting plate 3, thereby improving the rotational stability between it and the housing.

[0066] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. All modifications, equivalent substitutions, improvements, etc., within the spirit and principles of this application are included within the scope of protection of this application.
