Example 1

As shown in fig. 1 to 7, the present embodiment provides a high heat dissipation box door, which includes a door frame 1, a first partition 21, a second partition 22, a third partition 23, a blower 3, a cold air channel 4, a hot air channel, a sealing heat insulation frame 6, and a handle 7. The door body of the door of the embodiment is roughly in a cuboid structure, the first partition plate 21, the second partition plate 22 and the third partition plate 23 are sequentially fixed in the door frame 1 from outside to inside in parallel, and the handle 7 is installed at the top of the outer side surface of the door body. The first partition 21 and the second partition 22 are spaced 18mm apart, and the second partition 22 and the third partition are spaced 4mm apart. The area of the third partition plate 23 is larger than that of the second partition plate 22, and after the installation is completed, four sides of the second partition plate 22 protrude with respect to four sides of the third partition plate 23. In this embodiment, the first partition 21, the second partition 22 and the third partition 23 are all made of tempered glass, and the door frame 1 and the handle 7 are made of PC plastic.

As shown in fig. 4 and 5, the door of this embodiment further includes a sealing and heat insulating frame 6 wrapping the periphery of the third partition 23, and the sealing and heat insulating frame 6 is made of silicone. As shown in FIG. 4, the sealing and heat insulating frame 6 has a cross section composed of an asymmetric U-shaped structure 61 and an everted convex structure 62. The U-shaped bottom of the asymmetric U-shaped structure wraps the edge of the third partition plate 23, the longer U-shaped side of the asymmetric U-shaped structure is clamped and fixed by the second partition plate 22 and the third partition plate 23, and the U-shaped bottom of the asymmetric U-shaped structure 61 wraps the periphery of the third partition plate 23. Therefore, the sealing and heat insulating frame 6 firmly wraps the periphery of the third partition plate 23, and the sealing and heat insulating frame 6 is prevented from easily falling off in the using process. The protruding structure 62 is connected to the shorter U-shaped edge of the asymmetric U-shaped structure 61, and the protruding structure 62 forms an arc-shaped protrusion toward the inner side of the door.

As shown in fig. 7, a rectangular parallelepiped space is formed between the first partition 21 and the second partition 22 of the present embodiment, the blower 3 is installed at the top corner of the space, and an air inlet hole 24 and an air outlet hole 25 are formed at both bottom corners of the space to communicate the space with the external space of the door, wherein the air inlet hole 24 is disposed right below the blower 3 and the air outlet hole 25 is disposed at the diagonal of the blower 3. The space is divided into a cold air channel 4 and a hot air channel by using the reinforcing ribs, wherein the cold air channel 4 is not communicated with the hot air channel, the cold air channel 4 is communicated with an air suction opening 31 and an air inlet 24 of the air blower 3, and the hot air channel is communicated with an air outlet 32 and an air exhaust hole 25 of the air blower 3. The hot air channel of the present embodiment is divided into a first hot air channel 51 and a second hot air channel 52 by the reinforcing rib to form a zigzag structure, and specifically, the first hot air channel 51 surrounds the second hot air channel 52. The first hot air passage 51 communicates with the exhaust hole 25. The wall of the second hot air duct 52 is provided with a through hole 53 at the corner closest to the exhaust hole 25 for communicating with the first hot air duct 51.

Referring to fig. 8, the working principle of the high heat dissipating box door of the present embodiment is as follows:

the blower 3 is started, air in the space outside the door sequentially passes through the air inlet 24 and the cold air channel 4 to enter the air suction opening 31 of the blower 3 under the suction action of the blower 3, and the air flows in the direction of the hollow arrow shown in fig. 8. After the conversion of the impeller inside the blower 3, the air entering the blower 3 enters the hot air channel through the air outlet 32. There are three flow directions of air entering the hot air channel, see the solid arrows in fig. 8: moves downward along the first hot air passage 51; moving laterally along the first hot air path 51; into the second hot air path 52 and then into the first hot air path 51 through the through-hole 53. The air introduced into the hot air path is merged at a position where the first hot air path 51 is adjacent to the exhaust hole 25 and is finally exhausted to the external space of the door through the exhaust hole 25. Therefore, the air blower 3 is adopted to suck room temperature air into the box door, the air blower 3 applies work to increase the flow velocity of the air, and therefore the heat in the box door is effectively taken away by utilizing the principles of heat transfer cooling and mass transfer cooling. In addition, this embodiment is through setting up the trend of cold wind passageway 4 and hot-blast passageway rationally: air is sucked from the right lower part of the blower 3, so that the efficiency of sucking the air by the blower 3 to do work is improved; the air discharged by the air blower 3 flows to three different directions in the hot air channel respectively, so that the air can be fully contacted with the inside of the box door, and the effect of full heat transfer and temperature reduction is achieved.

Example 2

The embodiment provides an oven, wherein the oven body is provided with the oven door provided by the embodiment 1, and the bottom of the oven door is hinged with the bottom of the opening of the oven body. After the door is closed, the gap formed between the door and the opening of the box body is completely sealed by the convex structure 62 at the periphery of the sealing heat insulation frame 6. Compared with the traditional plane sealing and heat insulating layer, the design of the convex structure 62 can more tightly wrap the gap between the door body and the box body, particularly the gap at the corner position, and has good heat insulating and sealing effects.

When the oven of the present embodiment is used, the blower 3 inside the door is turned on, and the heat inside the door is taken away by the air flowing through. Even in the heating process of the oven, the blower 3 can take away the heat of the oven door, so that the heat accumulation is avoided, the temperature of the front side surface of the first clapboard 21 of the oven door does not exceed the CE standard, and a user can obtain safe and comfortable use feeling.
