[0049] Embodiment 1

[0050] like Figure 1 and Figure 2 As shown, this embodiment provides a door structure, which is applied to a kitchen appliance. The kitchen appliance may be a disinfection cabinet, etc. This embodiment is described by taking the disinfection cabinet as an example.

[0051] like Figures 1 to 3As shown, the door structure includes a front panel 10, a handle 20 and a door lining 30. The front panel 10 is provided with a through mounting hole 11. The door lining 30 is connected to the rear side of the front panel 10. At least part of the handle 20 is located between the front panel 10 and the door lining 30. The handle 20 has a handle channel 2121 connected to the mounting hole 11. The user's finger can be inserted into the handle channel 2121 to pull the door structure. The handle 20 is snap-fitted with the front panel 10. In an optional embodiment, the front panel 10 is a glass panel with high hardness and long service life, avoiding frequent maintenance and replacement; the door lining 30 is a sheet metal part, which can enhance the overall strength of the door structure and provide a good shielding and protection effect on the handle 20 to ensure aesthetics.

[0052] The door structure provided in this embodiment has a handle 20 that is directly fixed to the front panel 10 by a snap-fitting manner, which facilitates the installation and fixation of the handle 20. Compared with the screw fixing method and the glue fixing method in the prior art, this snap-fitting method reduces the use of screws and does not need to wait for the glue to air-dry. The installation is convenient and quick, which improves the installation efficiency. There is no need to lock the screws on the door lining 30, thereby improving the appearance of the door lining 30.

[0053] In an optional embodiment, if Figure 3 and Figure 5 As shown, the handle 20 is provided with a first slot 2133, and the side of the mounting hole 11 is snapped into the first slot 2133. During installation, the handle 20 is inserted into the mounting hole 11 of the front panel 10 from front to back, and then the side of the mounting hole 11 is snapped into the first slot 2133, which not only realizes a stable and reliable connection between the handle 20 and the front panel 10, but also makes installation convenient and quick, thereby improving installation efficiency.

[0054] In another optional embodiment, a first clamping portion may be provided on the handle 20, and a second clamping portion may be provided on the front panel 10, and the handle 20 may be clamped to the front panel 10 by the clamping cooperation between the first clamping portion and the second clamping portion. Exemplarily, the first clamping portion and the second clamping portion may be in the form of a clamping hook and a clamping slot or a clamping hook and a clamping hole. Of course, the first clamping portion and the second clamping portion may also be in other structural forms, as long as the clamping structure can clamp the handle 20 to the front panel 10, and no specific limitation is made here.

[0055] In an optional embodiment, if Figure 5As shown, the handle 20 includes a stop plate 211 and a handle portion 212. The stop plate 211 is connected to the front end periphery of the handle portion 212 and fits with the front side surface 12 of the front panel 10. The handle portion 212 is passed through the mounting hole 11 and is located between the front panel 10 and the door lining 30. The handle channel 2121 mentioned above is formed in the handle portion 212. During installation, first penetrate the mounting hole 11 of the handle portion 212 from front to back, and then snap the side of the mounting hole 11 into the first slot 2133. After the snapping is completed, the stop plate 211 fits with the front side surface 12 of the front panel 10 to form a limit. The fitting area of ​​the stop plate 211 and the front panel 10 is large, thereby ensuring the stability of the snap-fit. In addition, the handle portion 212 is completely embedded in the front panel 10, and only the stop plate 211 is exposed to the outside and fits tightly with the front panel 10, so that the handle 20 is constructed as a built-in handle, which has a better appearance.

[0056] Specifically, Figure 5 As shown, a supporting rib 213 is provided on the upper side of the handle portion 212, and the supporting rib 213 includes a first height portion 2131 and a second height portion 2132 connected to each other, and the first height portion 2131 is lower than the second height portion 2132 to form a gap, and the stop plate 211 is connected to the first height portion 2131, thereby blocking the front side of the gap to form a U-shaped first slot 2133. This arrangement ensures that the side edge of the mounting hole 11 can be stably stuck in the first slot 2133, while allowing the stop plate 211 to fit exactly with the front side 12 of the front panel 10, which is convenient and quick to install, and has a simple structure and is convenient for processing and manufacturing.

[0057] In an optional embodiment, if Figure 5 As shown, four supporting ribs 213 are provided on the upper side of the handle portion 212, thereby forming four first slots 2133 to ensure that the side of the mounting hole 11 can be stably clamped in the multiple first slots 2133. Among them, two supporting ribs 213 are located at the left end of the handle portion 212, and the other two supporting ribs 213 are located at the right end of the handle portion 212. The two supporting ribs 213 located at the same end of the handle portion 212 are connected together by reinforcing ribs to ensure the structural strength of the supporting ribs 213. In other embodiments, if the space on the upper side of the handle portion 212 allows, other numbers of supporting ribs 213 can also be provided, which is not specifically limited here.

[0058] In an optional embodiment, if Figures 3 to 5As shown, the lower side of the handle 20 is also provided with a limiting groove 221, which is roughly an L-shaped groove. Specifically, the limiting groove 221 includes a first stop surface 2211 and a second stop surface 2212 arranged at an angle, the first stop surface 2211 abuts against the lower hole wall of the mounting hole 11, and the second stop surface 2212 abuts against the rear side surface 13 of the front panel 10. When the upper side of the mounting hole 11 is clamped in the first clamping groove 2133, the lower side of the mounting hole 11 is also clamped in the limiting groove 221, the first stop surface 2211 abuts against the lower side wall of the mounting hole 11 to limit the downward movement of the handle 20, and the second stop surface 2212 abuts against the rear side surface 13 of the front panel 10 to limit the forward movement of the handle 20. The limiting groove 221 and the first card groove 2133 jointly realize the stable and reliable connection between the handle 20 and the front panel 10. Compared with the U-shaped first card groove 2133 arranged around the handle 20, by setting the L-shaped limiting groove 221 on the lower side of the handle 20, the clamping installation of the handle 20 can be more convenient and quicker.

[0059] In another optional embodiment, the first locking groove 2133 is disposed on the lower side of the handle portion 212, and the limiting groove 221 is disposed on the upper side of the handle portion 212, which can also achieve the above-mentioned locking effect and will not be described in detail here.

[0060] In the prior art, the top of the handle portion 212 is usually not closed, and the door lining 30 of the disinfection cabinet has a high temperature. When the user pulls the handle 20, the fingers are easily extended from the top of the handle portion 212 and touch the door lining 30 and are burned by the high temperature, resulting in a poor user experience.

[0061] In order to solve the above problem, in an optional embodiment, as Figure 5 and Figure 6 As shown, the handle 20 specifically includes a handle body 21 and a blocking member 22. The handle body 21 includes the above-mentioned stopper plate 211, a handle portion 212 and a supporting rib plate 213. A top opening 2122 is provided at the top of the handle body 21, and the top opening 2122 is communicated with the handle channel 2121. The blocking member 22 is detachably connected to the handle body 21 and blocks the top opening 2122. The blocking member 22 is used to block the top opening 2122 to prevent the user's fingers from passing through the top opening 2122 when pulling the handle 20, thereby preventing the user from touching the high-temperature door lining 30 and preventing the user from being scalded by the door lining 30, thereby improving the user's experience.

[0062] It is worth noting that the handle body 21 is an integrally formed structure, and the blocking piece 22 is an integrally formed structure, and the handle body 21 and the blocking piece 22 are detachably connected by a snap-fitting manner.

[0063] refer to Figure 5The blocking member 22 is a cover with a bottom opening, and the top of the cover is closed. The cover is placed on the top opening 2122 of the handle body 21 to close the top opening 2122. The handle portion 212 includes a back plate 2123 located at the rear side, and the back plate 2123 is an arc-shaped plate that bends backward. The blocking member 22 includes a rear end plate 224 located at the rear side. When the blocking member 22 is placed on the top opening 2122, the front end surface of the blocking member 22 abuts against the rear end surface of the stop plate 211, and the gap between the upper ends of the two can also be clamped by the upper side of the mounting hole 11. The rear end plate 224 of the blocking member 22 fits outside the back plate 2123 of the handle portion 212.

[0064] In an optional embodiment, if Figure 7 As shown, a first clamping structure 214 is provided on the left and right side walls of the top opening 2122, and a second clamping structure 222 is provided on the left and right sides of the blocking member 22. The first clamping structure 214 is clamped with the second clamping structure 222, thereby achieving stable clamping between the handle body 21 and the blocking member 22, and the installation is convenient and quick.

[0065] In an optional embodiment, if Figures 7 to 9 As shown, the first clamping structure 214 includes a third stopper 2142 and a fourth stopper 2143, the third stopper 2142 is arranged above the fourth stopper 2143 to define a slot 2141 together; the second clamping structure 222 includes a plug-in board 2221 and an elastic arm 2222, the elastic arm 2222 is arranged at a distance on the front side of the plug-in board 2221, the plug-in board 2221 is plugged and matched with the slot 2141, and the elastic arm 2222 can abut against the front side of the third stopper 2142. The third stopper 2142 can be a columnar structure or a plate-like structure, the fourth stopper 2143 can be a plate-like structure, and the elastic arm 2222 gradually tilts upward from the front to the back in a free state and can undergo elastic deformation.

[0066] When assembling the handle body 21 and the blocking member 22, the blocking member 22 is first covered on the back plate 2123 of the handle body 21, and then the blocking member 22 is slid from the back to the front, and the elastic arm 2222 is first inserted into the slot 2141. At the same time, under the extrusion of the third limiting member 2142, the elastic arm 2222 is deformed. When the front end face of the blocking member 22 abuts against the rear end face of the stop plate 211, the plug-in plate 2221 is plugged into the third limiting member 2141. 2 and the fourth limiting member 2143 to limit the up and down movement of the blocking member 22. At the same time, the elastic arm 2222 is reset and abuts against the front side of the third limiting member 2142, thereby limiting the backward movement of the blocking member 22. At the same time, the stop plate 211 limits the forward movement of the blocking member 22, thereby realizing the up and down front and back limiting of the blocking member 22, ensuring the stable and reliable connection between the blocking member 22 and the handle body 21, and the installation process is convenient and quick.

[0067] In an optional embodiment, if Fig.10 and Fig.11 As shown, the blocking member 22 also includes two legs 225, which are formed by the left and right ends of the rear end plate 224 of the blocking member 22 being bent and extended downward, and the legs 225 are attached to the outside of the back plate 2123 of the handle body 21.
