The specific structure of the door body will be mainly described below.

Referring to fig. 1 to 6, in an embodiment of the present invention, a door is used for a cooking apparatus, the door including:

the number of the door panels 100 is such that,

the handle 300, the handle 300 is fixedly connected with the door panel 100;

and a heat sink 200, wherein the heat sink 200 is mounted on the door panel 100 corresponding to the handle 300.

Specifically, in the present embodiment, the door panel 100 may have many forms, and may be a flat plate, or a plate-shaped structure having a folded edge or a flanged edge. The door panel 100 has a trim panel 400 surface 110 and a mounting panel surface 120 disposed opposite the trim panel 400 surface 110. When the door body is closed, the decorative panel 400 faces the user at the face 110, and the installation panel face 120 faces the cooking cavity. The decorative plate 400 may be disposed on the surface 110 of the decorative plate 400, and the decorative plate 400 may have various forms and materials, such as a transparent material, for example, a glass panel. The handle 300 is disposed at an end of the door panel 100 away from the door body. The handle 300 may be disposed on the decorative board 400 surface 110 of the door panel 100, or may be disposed on the installation board surface 120, for example, on the installation board surface 120, so as to facilitate installation of the decorative board 400 and more reasonably utilize the space. The form of the handle 300 may be many, for example, in a plate shape, and the handle 300 is disposed in parallel to the door panel 100, so that the space may be more reasonably utilized, and the space occupied by the handle 300 may be reduced. The handle 300 may be made of many materials, such as plastic.

The form of the heat sink 200 may be various, such as square, triangular, circular, etc., as an example, corresponding to the shape of the pull 300. In other embodiments, the handle 300 is provided with a grip area 310 for holding by a user. Handle area 310 is for example arranged in a square shape, and heat sink 200 is arranged corresponding to handle area 310. The heat sink 200 may be disposed on the mounting plate surface 120 of the door panel 100, i.e., the plate surface facing the handle 300; or may be disposed on the surface 110 of the decorative plate 400, i.e., the surface facing the decorative plate 400. For example, the decorative plate 400 is provided on the surface 110. The heat sink 200 may be made of various materials, such as a ceramic sheet, a metal sheet, etc., and the metal heat sink 200 may be a copper sheet, an aluminum sheet, etc. The thickness of the heat sink 200 is 1 to 3mm, for example, 2 mm. When the thickness of the heat sink 200 is too thick, the installation thereof is not facilitated, and meanwhile, the thickness of the door body may need to be increased; when the thickness of the heat sink 200 is too thin, the heat absorption and dissipation effects are not good.

In this embodiment, the heat sink 200 absorbs the heat of the door panel 100 or the handle 300 in time, and when the heat sink 200 absorbs the heat of the handle 300, the heat is rapidly transferred to the air around the door panel 100 and the heat sink 200, so as to rapidly cool the handle 300; when the heat sink 200 absorbs the heat of the door panel 100, the heat is rapidly transferred to the surrounding air, so as to rapidly cool the door panel 100; of course, in some embodiments, since the door panel 100 is connected to the handle 300, the heat may also be transferred from the handle 300 to the door panel 100, then from the door panel 100 to the heat sink 200, and then from the heat sink 200 to dissipate the heat.

In order to improve the mounting stability of the heat sink 200 and improve the heat dissipation effect of the heat sink 200, the door panel 100 is provided with a mounting groove 150, and the heat sink 200 is disposed in the mounting groove 150. The mounting groove 150 may be formed in the decorative plate 400 surface 110 of the door panel 100 or in the mounting plate surface 120 of the door panel 100, and may be formed in the decorative plate 400 surface 110, for example. Through the arrangement of the mounting groove 150, the mounting stability of the heat radiating fin 200 can be improved, the heat radiating fin is prevented from being influenced by external factors (such as collision), meanwhile, the space is fully and reasonably utilized, and the thickness of a door body is prevented from being increased; in addition, the contact area between the door panel 100 and the heat sink 200 is increased, which is beneficial to the heat transfer between the heat sink 200 and the door panel 100 and the improvement of the heat dissipation efficiency of the heat sink 200.

In some embodiments, in order to further and rapidly absorb the heat of the handle 300, a heat sink 130 is disposed on the door panel 100 at a position corresponding to the handle 300, and the heat sink 200 is disposed corresponding to the heat sink 130. The heat of the handle 300 can be rapidly transferred to the heat sink 200 through the heat dissipating port 130, and then transferred from the heat sink 200 to the surrounding air to neutralize the door panel 100, which is beneficial to improving the efficiency of transferring heat energy from the handle 300 to the heat sink 200, so that the temperature of the handle 300 can be rapidly reduced.

In some embodiments, in order to improve the heat dissipation efficiency of the door panel 100 or the pull handle 300, the pull handle 300 includes a handle area 310, the door panel 100 and the handle area 310 have a first heat dissipation gap 140 therebetween, and the heat sink 200 is disposed corresponding to the handle area 310. Through the arrangement of the first heat dissipation gap 140, the heat in the handle area 310 can be rapidly transferred to the first heat dissipation gap 140, which is beneficial to rapid cooling. When the heat dissipation opening 130 is opened, the first heat dissipation gap 140 also increases the contact area between the heat dissipation plate 200 and the air, thereby facilitating the heat dissipation plate 200 to dissipate the heat energy into the air.

In order to further improve the heat dissipation efficiency, the handle 300 further includes a heat dissipation area 320 connected to the handle area 310, a second heat dissipation gap is formed between the heat dissipation area 320 and the door panel 100, and the first heat dissipation gap 140 and the second heat dissipation gap are communicated to form a heat dissipation cavity. Through the arrangement of the heat dissipation cavity, the contact area between the handle 300 and the air is increased, and the contact area between the heat dissipation fins 200 and the air is also increased, so that the handle 300 and the heat dissipation fins 200 are facilitated to transfer heat energy to the air, and the heat energy in the first heat dissipation gap 140 is also facilitated to be rapidly dissipated to the second heat dissipation gap.

In order to improve the heat dissipation efficiency, the distance of the second heat dissipation gap is greater than the distance of the first heat dissipation gap 140. The distance between the heat dissipation area 320 and the door panel 100 is set to be greater than the distance between the handle area 310 and the door panel 100, that is, the distance between the heat dissipation area 320 and the door panel 100 is set to be greater than the distance between the handle area 310 and the door panel 100, so that the heat dissipation space is increased, heat exchange with more air is facilitated, meanwhile, the air with higher temperature in the first heat dissipation gap 140 is rapidly diffused into the second heat dissipation gap with lower temperature, and the heat dissipation speed of the handle area 310 and the heat dissipation fins 200 is improved.

In order to further improve the heat dissipation effect, heat energy is dissipated to the air around the door body in time, the side wall of the heat dissipation cavity is provided with a heat dissipation hole 330, and the heat dissipation hole 330 is communicated with the heat dissipation cavity and the outside of the door body. The heat dissipation holes 330 may be formed at a plurality of positions, such as the heat dissipation area 320 of the handle and the door panel 100. Taking the narrow side walls arranged around the heat dissipation cavity as an example, the heat energy can be quickly transferred to the air without influencing the overall structure of the door body. Specifically, flanges are disposed on the side of the door panel 100 and/or the side of the handle 300, the flanges are sidewalls of the heat dissipation cavity, and the heat dissipation hole 330 is located on the flanges. The heat dissipation holes 330 may be opened at one or more positions of the bottom, the left side, the right side, and the top of the door panel 100. Taking the heat dissipation hole 330 as an example, the heat dissipation hole 330 is located at the top of the door body, so that the heat dissipation hole 330 is beneficial to dissipating heat energy in time due to the upward trend of heat. It should be noted that the shape of the heat dissipation hole 330 may be various, such as circular, triangular, polygonal, etc. The number of the heat dissipation holes 330 is plural, and the plurality of heat dissipation holes 330 are arranged along the length direction or the width direction of the door panel.

In some embodiments, for better heat dissipation of the heat sink 200, the door body further includes the door panel 100 having a decorative panel 400 surface 110 and a mounting panel surface 120, and the handle 300 is disposed on the mounting panel surface 120; the door body still includes decorative board 400, decorative board 400 set up in on the decorative board 400 face 110, fin 200 with the laminating of decorative board 400. By attaching the heat sink 200 to the glass panel, a part of the heat sink 200 can be rapidly transferred to the glass panel and then dissipated from the glass panel to the air around the door body, which is beneficial to rapid dissipation of the heat.

The invention further provides cooking equipment, which comprises a box body and a door body, wherein the specific structure of the door body refers to the embodiments, and the cooking equipment adopts all the technical schemes of all the embodiments, so that the cooking equipment at least has all the beneficial effects brought by the technical schemes of the embodiments, and the details are not repeated.
