[0003] The cooking equipment currently on the market that integrates display components into the door body usually adopts a solution of opening many ventilation holes on both sides and the top of the door body to increase the passive heat dissipation capacity of the door body, and uses four layers of door glass for heat insulation. However, the heat dissipation capacity of this solution is very limited, and the insulation structure of the four layers of door glass makes the overall structure of the entire door assembly relatively thick. The large number of openings also makes it easy for external impurities to enter the door body, causing the door body to harbor dirt. Utility Model Content

The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.

[0031] In order to improve the aesthetics and integration level of the entire cooking equipment, the existing cooking equipment integrates the screen assembly with the door body. However, the door body with integrated screen assembly has higher requirements for heat dissipation, and the door bodies on the market have the problem of insufficient heat dissipation capacity.

[0032] In view of the above problems, the utility model provides a heat dissipation door body 100, which is applied to cooking equipment and can actively dissipate heat. It has the advantages of good heat dissipation capacity and beautiful appearance.

[0033] It needs to be explained that the above-mentioned cooking equipment is equipment that can generate heat and cook food, such as steamers, ovens, and steam ovens, etc. As long as the equipment will affect the door panel due to the high internal temperature during the cooking process, it is the object referred to by the above-mentioned cooking equipment, and is not limited to the above-mentioned equipment such as steam ovens.

[0034] See also Figure 1 The heat dissipation door body 100 includes a door body 10, a partition assembly 20, a screen assembly 30 and an air cooling assembly 40. The door body 10 is constructed with a cavity 13. An air inlet 11 and an air outlet 12 are opened on the door body 10. The air inlet 11 and the air outlet 12 are both connected to the cavity 13. The partition assembly 20 is installed in the cavity 13 and can separate the cavity 13 into a first cavity 131 and a second cavity 132. The screen assembly 30 is installed in the first cavity 131 and connected to the cavity wall forming the first cavity 131, and can display information to the outside through the door body 10. The air cooling assembly 40 is installed in the first cavity 131 and connected to the cavity wall forming the first cavity 131, and can accelerate the heat exchange between the first cavity 131 and the external environment.

[0035] In this way, the air inlet 11 on the door body 10 allows the outside air to enter, and the air outlet 12 allows the air entering the cavity 13 to flow out. The air inlet 11 and the air outlet 12 form convection, which promotes the air flow inside the door body 10 and speeds up the heat exchange rate between the air inside the door body 10 and the outside air. The screen assembly 30 and the door body 10 are integrated together, and information can be displayed to the outside world through the door body 10, saving the cost of setting up additional components such as the screen assembly 30 bracket, and improving the integration of the whole system. The screen assembly 30 that interacts with the user is integrated on the door body 10, which is more beautiful and convenient to clean than the separate design. The partition assembly 20 divides the cavity 13 into a first cavity 131 and a second cavity 132, and the screen assembly 30 and the air cooling assembly 40 are both arranged in the first cavity 131. The air cooling assembly 40 can actively accelerate the air flow rate in the first cavity 131 to increase the heat exchange rate between the first cavity 131 and the external environment, thereby making the first cavity 131 cool down faster. The first cavity 131 separated by the partition assembly 20 reduces the spatial volume required for the air cooling assembly 40 to act, thereby further improving the cooling efficiency of the air cooling assembly 40 to provide the screen assembly 30 with a better working environment.

[0036] In order to enable the door body 10 to adapt to different working requirements and produce different heat dissipation positions and heat dissipation capabilities, the present application provides multiple embodiments, which achieve the adaptation of the heat dissipation door body 100 to different working conditions by changing the internal structure of the heat dissipation door body 100, which are explained one by one here.

[0037] Embodiment 1

[0038] See also Figure 1-Figure 2 The partition assembly 20 is provided with a connecting port 211, and the first cavity 131 and the second cavity 132 are connected through the connecting port 211. Thus, the connecting port 211 allows the air in the first cavity 131 and the second cavity 132 to flow, and the air blown by the air cooling assembly 40 can enter the second cavity 132 through the connecting port 211, thereby simultaneously accelerating the air flow rate in the second cavity 132, so that the speed of heat exchange between the second cavity 132 and the outside is also simultaneously increased, thereby optimizing the heat dissipation capacity of the entire door body 10.

[0039] The partition assembly 20 includes a partition plate 21 and an air guide plate 22. The partition plate 21 is connected to the inner wall forming the cavity 13 and extends laterally. The communication port 211 is opened on the partition plate 21. At least one end of the partition plate 21 in the length direction is connected to the air guide plate 22. The air guide plate 22 is bent in a direction away from the second cavity 132 to form an air outlet 12 connected to the outside. The air outlet 12 is connected to the second cavity 132. In this way, the air in the first cavity 131 can enter the second cavity 132 through the partition plate 21. The air guide plate 22 is bent in a direction away from the second cavity 132 to form the air outlet 12. Therefore, the air can form a circulating convection in the second cavity 132 and still needs to return to the position of the partition plate 21 in the end, thereby enhancing the turbulence in the second cavity 132, thereby improving the heat dissipation effect in the second cavity 132. Moreover, the air inlet 11 and the air outlet 12 are both located at the position of the partition assembly 20, which makes the layout simpler.

[0040] It should be explained that the above-mentioned "lateral extension" refers to extension tending to the horizontal direction. In this embodiment, the partition assembly 20 extends along the horizontal direction (i.e., along the platform parallel to the cooking device used by the heat dissipation door body 100), and separates the cavity 13 into a first cavity 131 and a second cavity 132 located above. In other embodiments, the partition assembly 20 can also be offset by a certain angle relative to the parallel direction.

[0041] Preferably, in this embodiment, air guide plates 22 are provided at both ends of the partition plate 21. The air guide plates 22 located at both ends of the partition plate 21 are symmetrically arranged and can form air outlets 12. Therefore, the air in the cavity 13 can flow out from both sides, thereby improving the efficiency of heat exchange and air flow between the heat dissipation door body 100 and the outside.

[0042] Furthermore, the partition assembly 20 further includes a cover plate 23, which is disposed on the side of the air guide plate 22 facing away from the partition plate 21, and the air outlet 12 is formed on the cover plate 23, and a plurality of air outlets 12 are provided on one cover plate 23 and are arranged at intervals. In this way, the cover plate 23 can reduce the impurities in the external environment from entering the second cavity 132 and the first cavity 131 through the air guide plate 22, and the air outlet 12 is opened on the cover plate 23, which facilitates the opening and processing of the air outlet 12.

[0043] Embodiment 2

[0044] See also Figure 3-Figure 5 In this embodiment, the air inlet 11 and the air outlet 12 are both opened on the cavity wall forming the first cavity 131, and the air inlet 11 and the air outlet 12 are respectively located at both ends of the first cavity 131 in the horizontal direction. In this way, air can enter from one end of the first cavity 131 and then flow out from one end of the first cavity 131, so that the air can quickly take away the heat in the first cavity 131 to reduce the temperature of the first cavity 131.

[0045] In this embodiment, the partition assembly 20 does not have a connecting port 211 , so the air cooling assembly 40 does not need to speed up the air flow in the second cavity 132 , thereby improving the cooling effect of the air cooling assembly 40 on the first cavity 131 .

[0046] Embodiment 3

[0047] See also Figure 6 In this embodiment, the air inlet 11 is opened on the cavity wall forming the first cavity 131, and the heat dissipation door body 100 includes a heat insulation cover 50, which is connected to the cavity wall forming the first cavity 131 and is surrounded to form a heat insulation cavity, and the screen assembly 30 is arranged in the heat insulation cavity. In this way, the heat insulation cover 50 can isolate the screen assembly 30 from direct contact with the high-temperature air in the first cavity 131, thereby delaying the temperature rise of the screen assembly 30 and reducing the impact of the high-temperature air in the first cavity 131 on the screen assembly 30.

[0048] Furthermore, the heat dissipation door body 100 further includes an air duct structure 52, one end of which is connected to the air inlet 11, and the other end is connected to the heat insulation cavity. At least one side of the heat insulation cover 50 is provided with a plurality of first heat dissipation holes 51, and the plurality of first heat dissipation holes 51 are evenly spaced along the length direction of the heat insulation cover 50, and the heat insulation cavity is connected to the first cavity 131 through the first heat dissipation holes 51. In this way, the air entering the cavity 13 through the air inlet 11 can also enter the heat insulation cavity, so as to dissipate heat from the heat insulation cavity alone, and the plurality of first heat dissipation holes 51 enable the air in the heat insulation cavity to flow out, thereby preventing the air from being stagnant in the heat insulation cavity, and the plurality of first heat dissipation holes 51 evenly spaced can promote the air to flow out of the heat dissipation cavity.

[0049] In addition, based on the above three embodiments, the present application also provides other technical features that are conducive to the realization of technical effects.

[0050] The door body 10 includes an outer panel 14, an inner panel 15 and a door handle 16. A cavity 13 is defined between the outer panel 14 and the inner panel 15. The door handle 16 is connected to the top of the outer panel 14. The air inlet 11 is opened at the top of the outer panel 14. The side of the outer panel 14 away from the inner panel 15 is the outer side. The door handle 16 extends toward the bottom of the outer panel 14 and blocks the outer side of the air inlet 11. In this way, since the air inlet 11 is opened at the top of the outer panel 14, it is convenient to process and open, and it can avoid affecting the structural strength of the door body 10. Since the door handle 16 can block the outer side of the air inlet 11, it is more beautiful and indirect, and it can also prevent impurities and dust in the external environment from entering the inner part of the outer panel 14.

[0051] Furthermore, the air cooling assembly 40 is installed on the side of the inner plate 15 facing the outer plate 14, and is spaced apart from the outer plate 14. In this way, it is convenient for air to enter the space between the outer plate 14 and the inner plate 15 from the air inlet 11, and the air enters the space at a certain distance so that the air enters more smoothly, thereby improving the heat exchange efficiency.

[0052] Of course, it is understandable that in other embodiments, the air cooling assembly 40 can also be directly mounted on the outer plate 14 to act as a suction fan to directly draw air from the outside, without being limited to the above-mentioned embodiment in which the air cooling assembly 40 is spaced apart from the outer plate 14 .

[0053] The door body 10 further includes a connecting plate 17, one side of which is connected to the inner plate 15, and the other end of which is connected to the door handle 16, thereby blocking the top area of ​​the space formed between the inner plate 15 and the outer plate 14, which is conducive to enclosing the cavity 13. At least one second heat dissipation hole 171 is opened on the connecting plate 17, thereby promoting the outflow of high-temperature gas in the cavity 13.

[0054] The door body 10 further includes a middle plate 18, which is connected to the partition assembly 20 and is located on the side of the partition assembly 20 facing away from the first cavity 131, thereby cooperating with the outer plate 14 to form a second cavity 132. That is, the outer side of the second cavity 132 is the outer plate 14, and the inner side is the middle plate 18. The inner plate 15 is also provided on the side of the middle plate 18 facing away from the outer plate 14. Since the position of the second cavity 132 usually corresponds to the heat concentration position of the cooking equipment, the additional middle plate 18 can further insulate and reduce the heat generation of the door body 10.

[0055] The utility model also provides a cooking device, comprising the heat dissipation door body 100 as described above. Hinge brackets 60 are arranged on both sides of the door body 10, and the hinge brackets 60 enable the door body 10 to be rotatably connected to the cooking device, so that the door body 10 can open or close the internal cooking space of the cooking device by rotating.

[0056] Compared with the prior art, the utility model sets an air inlet 11 and an air outlet 12 on the door body 10. The air inlet 11 allows external air to enter, and the air outlet 12 allows air entering the cavity 13 to flow out. The air inlet 11 and the air outlet 12 form convection, promote the air flow inside the door body 10, and accelerate the heat exchange rate between the air inside the door body 10 and the outside air. The screen assembly 30 and the door body 10 are integrated together, and information can be displayed to the outside world through the door body 10, saving the cost of additional parts such as the screen assembly 30 bracket, and improving the integration of the whole system. The screen assembly 30 that interacts with the user is integrated on the door body 10, which is more beautiful and convenient to clean than the separate design. The partition assembly 20 divides the cavity 13 into a first cavity 131 and a second cavity 132, and the screen assembly 30 and the air cooling assembly 40 are both arranged in the first cavity 131. The air cooling assembly 40 can actively accelerate the air flow rate in the first cavity 131 to increase the heat exchange rate between the first cavity 131 and the external environment, thereby making the first cavity 131 cool down faster. The first cavity 131 separated by the partition assembly 20 reduces the spatial volume required for the air cooling assembly 40 to act, thereby further improving the cooling efficiency of the air cooling assembly 40 to provide the screen assembly 30 with a better working environment.

[0057] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
