TECHNICAL FIELD

[0001] The utility model relates to cooking equipment technical field especially is related to a vacuum glass door body structure of cooking equipment. BACKGROUND

[0002] With the popularization of the application of the steam oven, people's requirements for its safety and energy saving are increasing. In actual use, especially in the baking mode of the steam oven, the high temperature of the internal cavity will be transmitted to the outer glass through the door body, resulting in a high surface temperature, which poses a risk of scalding the human body. In order to solve this problem, the door body structure design of the steam oven on the market is constantly improved.

[0003] At present, the technical solutions commonly used in the industry include the following: 1. Three-layer hollow glass design: by setting three layers of hollow glass in the door body, and forming a through structure in at least one hollow layer, the outer glass is cooled by the natural convection of cold air. However, during long-term use of the baking mode, due to the limited cooling efficiency, the temperature of the outer glass is still high, which is difficult to meet the safety requirements. 2. Forced convection cooling fan: some steam ovens use a fan to forcibly cool the glass, which can significantly improve the safety by reducing the temperature of the outer glass. However, this design increases the energy consumption of the equipment, which does not meet the energy saving requirements.

[0004] Based on the above problems, the existing technology cannot meet the needs of outer glass cooling effect and equipment energy saving. Therefore, how to design a steam oven door body structure that can significantly reduce the temperature of the outer glass and reduce energy consumption has become a problem that needs to be solved in the technical field.

DETAILED DESCRIPTION

[0028] The technical scheme of the present application will be described in detail below with reference to the drawings, and obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments.

[0029] Example 1

[0030] This embodiment provides a vacuum glass door structure for a cooking device, which aims to meet the energy-saving requirements of the device and effectively solve the problem of excessively high surface temperature of the outer glass of the door during the use of traditional ovens, which can easily cause burns.

[0031] Combined with appendix Figures 1-3 As shown in Figure 5, the device includes a vacuum glass 11 and an inner glass 12. The vacuum glass 11 consists of two pieces of glass stacked sequentially from the inside to the outside, with a vacuum layer 112 between the two pieces of glass. The vacuum glass 11 is located outside the inner glass 12, and a hollow channel 13 with openings at the top and bottom is provided between the vacuum glass 11 and the inner glass 12.

[0032] The inner glass 12 acts as a seal for the cooking equipment. A hollow channel 13 is provided between the inner glass 12 and the vacuum glass 11. The hollow channel 13 has openings at the top and bottom, allowing cold air to escape from the bottom of the cooking equipment upwards through the hollow channel 13, achieving heat dissipation through natural convection, thereby reducing the transfer of heat from the inner glass 12 to the vacuum glass 11. The vacuum layer 112 of the vacuum glass 11 effectively blocks the transfer of heat from the inner glass 113 to the outer glass 111, thereby reducing the surface temperature of the outer glass 111 of the vacuum glass 11.

[0033] A door frame 16 is provided around the periphery of the vacuum glass 11. The rotating side of the inner glass 12 is pivotally connected to the door frame 16 via a hinge structure 18. The opening and closing side of the inner glass 12 is fixed by a buckle 17 fixed on the door frame 16, and the locking of the opening and closing side of the inner glass 12 can be released by the buckle 17. That is, the inner glass 12 can rotate relative to the vacuum glass 11 of the door. After use, the user can press or pull the buckle 17 to release the locking of the inner glass 12, thereby opening the inner glass 12 and cleaning the hollow channel 13 between the inner glass 12 and the vacuum glass 11.

[0034] A heat insulation piece is arranged between the door frame 16 and the inner glass 12, and is connected with the door frame 16 and abuts against the inner glass 12. Specifically, the heat insulation piece comprises at least two side supports 14 and a flexible supporting pad 15 mounted on the side supports 14, the two side supports 14 are fixedly connected with the door frame 16 and are respectively located on the left and right sides of the door frame 16, and the flexible supporting pad 15 abuts against the inner glass 12. The flexible supporting pad 15 is preferably made of rubber material. The flexible supporting pad 15 abuts against the inner glass 12, so that there is a gap between the side support 14 and the inner glass 12, so that the heat on the inner glass 12 cannot be directly conducted to the side support 14 and the door frame 16, thereby avoiding the temperature rise of the outer surface of the door frame 16, and at the same time, a small part of the cold air entering the hollow channel 13 flows out from the gap, thereby improving the heat dissipation effect of the vacuum glass 11. The flexible supporting pad 15 can also play a shock-absorbing role during the opening and closing of the inner glass 12, thereby effectively preventing the inner glass 12 from being broken.

[0035] The door frame 16 is provided with a mounting cavity 161, and at least one side edge of the vacuum glass 11 extends into the mounting cavity 161 and directly abuts against the inner wall of the door frame 16 or is fixed by a limiting piece 162 arranged in the mounting cavity 161, and the limiting piece 162 is used for limiting the displacement of the vacuum glass 11.

[0036] By arranging the mounting cavity 161 in the door frame 16, the four peripheral edges of the vacuum glass 11 are inserted and fixed in the mounting cavity 161 and directly abut against the inner wall of the mounting cavity 161, or the limiting piece 162 is arranged in the mounting cavity 161 and abuts against the vacuum glass 11 to fix the vacuum glass 11, thereby preventing the glass from being displaced or falling off due to external force or vibration. The arrangement of the limiting piece 162 can compensate for the possible slight error in the installation process, so that the position of the vacuum glass 11 in the mounting cavity 161 is more accurate, thereby improving the overall assembly quality. In the embodiment, the limiting piece 162 is arranged on the left side and the right side of the vacuum glass 11 to limit the vacuum glass 11, so as to avoid the left and right movement of the vacuum glass 11.

[0037] The inner surface of the inner glass 12 and the surface of the vacuum glass 11 facing the inner glass 12 are both provided with a heat-reflecting coating.

[0038] Embodiment 2,

[0039] The difference between the embodiment and the embodiment 1 is that, in the embodiment, the vacuum glass 11 is combined with the door frame 16 by means of the limiting piece 162. Figure 4 As shown in the figure, the vacuum glass 11 comprises three glasses stacked from inside to outside, and a vacuum layer 112 is arranged between each two adjacent glasses, that is, two vacuum layers 112 are contained, so that the heat of the inner glass 113 is more effectively transmitted to the outer glass 111, thereby reducing the surface temperature of the outer glass 111.

[0040] Finally, it should be noted that: the above embodiments are used to illustrate the technical solutions of the present application, but not limited to them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
