Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0030] For details on the door structure of the steam oven, please refer to [link / reference]. Figure 1-3As shown, the door body 100 has an opening 101 that runs through the front and back, and also includes an outer glass layer 210, a middle glass layer 220 and an inner glass layer 230.
[0031] The outer glass 210 is fixedly installed in the opening 101, and the middle glass 220 and the inner glass 230 are rotatably installed on the door body 100 through the rotating assembly 300.
[0032] The door body 100 is provided with an LED light panel 500, which is installed from the back of the door body 100; the middle glass 220 and the inner glass 230 are superimposed on the outer glass 210, and the middle glass 220 covers the LED light panel 500.
[0033] In this technology, the LED light panel 500 is installed from the back of the door body 100. The back of the door body 100 should have a reserved position for the assembly of the LED light panel 500. This position can be a mounting position, a mounting groove, a support stud, etc.
[0034] If it is set as a support stud, then simply fix the LED light board to the support stud with a 500 screw.
[0035] After the middle glass 220 and the inner glass 230 are closed in the door body 100, the middle glass 220 and / or the inner glass 230 cover the LED light panel 500. When it is necessary to repair or replace the LED light panel 500, the middle glass 220 and the inner glass 230 can be opened, which is convenient and quick.
[0036] Optionally, in one embodiment, the middle glass 220 can cover the LED light panel 500. After the middle glass 220 is closed in the door body 100, the middle glass 220 covers the LED light panel 500. Then, when disassembling the LED light panel 500, the middle glass 220 and the inner glass 230 can be rotated open to expose the LED light panel 500, which facilitates the disassembly, maintenance or replacement of the LED light panel 500.
[0037] Optionally, in one embodiment, the middle glass 220 and the inner glass 230 may simultaneously cover the LED light panel 500. After the middle glass 220 and the inner glass 230 are closed on the door body 100, the middle glass 220 covers the LED light panel 500, while the inner glass 230 is superimposed on the middle glass 220 to further cover the LED light panel 500. Then, when disassembling the LED light panel 500, the middle glass 220 and the inner glass 230 are rotated open, and the LED light panel 500 is exposed, which facilitates the disassembly, repair or replacement of the LED light panel 500.
[0038] like Figure 2As shown, LED light panels 500 are installed on the left and right sides of the door body 100, and the middle glass 220 and the inner glass 230 simultaneously cover the LED light panels 500.
[0039] LED lights are installed on the LED light panel 500. The light from the LED lights shines through the middle glass 220 and the inner glass 230 onto the interior of the steam oven body.
[0040] In some embodiments, the rotating assembly 300 includes: a pivot, a first bushing fixed to the door body 100, a second bushing fixed to the middle glass 220, and a third bushing fixed to the inner glass 230; the pivot passes through the first bushing, the second bushing, and the third bushing.
[0041] In this technology, by means of a rotating shaft passing through the first bushing, the second bushing and the third bushing, the middle glass 220 and the inner glass 230 can be rotated relative to the door body 100.
[0042] Optionally, the rotating assembly 300 can also be changed to other corresponding structures, such as a shaft in the door body 100 and bushings in the middle glass 220 and inner glass 230, with the shaft simply inserted into the bushing.
[0043] like Figure 2 As shown, on one side of the middle glass 220 and the inner glass 230, the rotating assembly 300 is connected to both the upper and lower ends, so that the middle glass 220 and the inner glass 230 can rotate stably to open and close.
[0044] Furthermore, the door body 100 is provided with a buffer adhesive 110; after the middle glass 220 and the inner glass 230 are stacked on the outer glass 210, the middle glass 220 comes into contact with the buffer adhesive 110.
[0045] like Figure 2 As shown, on the back of the door body 100, multiple buffer rubbers 110 are distributed around the opening 101. The buffer rubbers 110 protrude in the direction away from the front of the door body 100. When the middle glass 220 is closed on the door body 100, it collides with the buffer rubbers 110 and plays a buffering role.
[0046] Furthermore, considering the difficulty of drilling holes in the glass to install the bushing, a bracket 201 is connected between the middle glass 220 and the inner glass 230, and the second bushing and the third bushing are respectively installed at the bracket 201.
[0047] like Figure 2As shown, brackets 201 are provided on the upper and lower sides of the middle glass 220 and the inner glass 230, respectively, and the second bushing and the third bushing are respectively provided at the brackets 201; the middle glass 220 and the inner glass 230 can be snap-fitted into the brackets 201 and fixed with glue.
[0048] Alternatively, the middle glass 220 and the inner glass 230 may also be welded to the bracket 201.
[0049] Furthermore, limiting components should be provided between the door body 100 and the middle glass 220, and between the middle glass 220 and the inner glass 230, so that the middle glass 220 and the inner glass 230 can be stably closed on the door body 100.
[0050] Optionally, the limiting structure can be a magnetic component, such as magnets that attract each other on the door body 100, the middle glass 220, and the inner glass 230, so that the middle glass 220 is magnetically attracted to the door body 100 and the inner glass 230 is magnetically attracted to the middle glass 220.
[0051] Optionally, the limiting structure can be a snap-fit structure, such as between the door body 100 and the middle glass 220, one side is provided with a snap-fit protrusion and the other side is provided with a snap-fit, which can be snapped and fixed; between the middle glass 220 and the inner glass 230, one side is provided with a snap-fit protrusion and the other side is provided with a snap-fit, which can be snapped and fixed.
[0052] Furthermore, the outer glass 210 can be glued and fixed in the opening 101. After the middle glass 220 and the inner glass 230 are rotated and closed in the door body 100, gaps are left between the outer glass 210 and the middle glass 220, and between the middle glass 220 and the inner glass 230, to reduce heat transfer to the outer glass 210.
[0053] The areas of the middle glass layer 220 and the inner glass layer 230 are both larger than the area of the outer glass layer 210, and the areas of the middle glass layer 220 and the inner glass layer 230 are the same.
[0054] A sealing ring may be provided on the door body 100. After the inner glass 230 is closed on the door body 100, the inner glass 230 and the door body 100 are sealed by the sealing ring to prevent steam from entering the gap between the outer glass 210 and the middle glass 220, and between the middle glass 220 and the inner glass 230.
[0055] Alternatively, a sealing ring can be provided on the main body of the steam oven corresponding to the edge of the steam oven cavity. When the door body 100 is closed in the main body of the steam oven, the sealing ring corresponds to the edge of the inner glass 230 and seals the gap between the inner glass 230 and the door body 100, preventing steam from entering the gap between the outer glass 210 and the middle glass 220, and between the middle glass 220 and the inner glass 230.
[0056] In one embodiment, the door body 100 is rotatably mounted to the oven body via a door hinge rotating assembly 400.
[0057] Furthermore, the door hinge rotation assembly 400 includes: a base 430 fixed to the main body of the steam oven, a first buffer 410 fixedly installed on the base 430, and a second buffer 420 fixed to the door body 100;
[0058] Between the first buffer 410 and the second buffer 420, one is provided with a wavy guide surface and the other is provided with a protrusion; when the door body 100 rotates relative to the steam oven body, the protrusion moves along the guide surface.
[0059] In this technology, the first buffer 410 and the second buffer 420 are designed to enable the door body 100 to open slowly relative to the oven body, preventing the door body 100 from opening rapidly and causing steam to release pressure quickly and burn the user, thus further ensuring safety.
[0060] Furthermore, the second buffer 420 is superimposed on the first buffer 410, and the guide surface is composed of alternating protrusions and concaves arranged in a circular pattern, with the protrusions supported on the guide surface; the first buffer 410 is provided with a first shaft portion 411, and the second buffer 420 is provided with a second shaft portion 421, with the first shaft portion 411 and the second shaft portion 421 sleeved together.
[0061] like Figure 3 As shown, the upper right side of the door body 100 can be directly connected to the main body of the steam oven via a pivot, while the lower right side of the door body 100 is connected to the main body of the steam oven via a door hinge rotating assembly 400.
[0062] The base 430 can be made of metal and can be fixed to the main body of the steam oven by screws; the first buffer 410 is fixedly installed on the base 430 and can be fixed by screws; the first buffer 410 is provided with a guide surface 412, which is distributed around the first shaft portion 411 and faces upward; the second buffer 420 is fixed to the bottom of the door body 100 and can be fixed by screws; the second buffer 420 is provided with a protrusion 422, which protrudes towards the guide surface 412;
[0063] The first shaft portion 411 and the second shaft portion 421 are sleeved together. When the door body 100 rotates, it rotates around the axis of the first shaft portion 411 and the second shaft portion 421. When the door body 100 rotates, when it rotates to the point where the protrusion 422 corresponds to the protrusion of the guide surface 412, it pushes the second buffer member 420 upward, thus pushing the door body 100 upward. When it rotates to the point where the protrusion 422 corresponds to the concave position of the guide surface 412, the second buffer member 420 falls down, and the door body 100 falls down.
[0064] like Figure 4 As shown, the height difference between the protrusion and the recess is relatively small, so the door body 100 shakes up and down a relatively small distance during the rotation and opening process, which can achieve the purpose of slowly opening the door body 100.
[0065] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
