Example 3

In the present embodiment, the periphery of the door body 2 is a stepped surface. Specifically, the joint of the first connecting body 4 and the second connecting body 5 is step-shaped, and the size of the second connecting body 5 is smaller than that of the first connecting body 4. Said second connecting body 5 is recessed towards the inside of the chamber 3. When the door 2 and the cabinet 1 are closed, the second connecting body 5 is at least partially disposed in the chamber 3 and closes the front opening of the cabinet 1. Even if the door body 2 is designed to be thick, the appearance is not affected. And a penetrating heat dissipation structure is arranged on the door body 2. When the oven is heating, hot air can flow out through the heat radiation structure, and external cold air can also enter through the heat radiation structure, avoids the door body 2 high temperature.

Specifically, at least one heat dissipation hole 6 is provided. The heat dissipation holes 6 are formed in the upper and lower circumferential surfaces of the second connector 5. The heat dissipation structure formed with the first flow channel 7 is formed to penetrate in the upper and lower directions of the door 2. Further, heat dissipation holes 6 may be further formed in the left and right peripheral surfaces of the second connector 5, and the heat dissipation structure may not only form a heat dissipation channel penetrating in the upper and lower directions of the door 2, but also form a heat dissipation channel penetrating in the left and right directions, thereby improving a heat dissipation area and a heat dissipation effect. The heat can flow out from all directions through the heat dissipation holes 6 around, and the external cold air can also enter the first flow channel 7 from all directions through the heat dissipation holes 6 around. The first flow channel 7 and the heat dissipation hole 6 formed by the front panel 9 and the middle panel 10 are communicated with each other to form an open space penetrating through the door body 2, so that heat is discharged, and heat accumulation near the front panel 9 is avoided.

The more the number and the larger the area of the heat dissipation holes 6 are, the more the heat dissipation effect is facilitated. However, how to ensure that the door body 2 has a good heat dissipation effect without affecting the mechanical strength thereof is a problem worthy of intensive research. The width of the second connector 5 is 3-20 mm. Here, the area of the heat dissipation hole 6 is defined as S1, and the area of the outer peripheral surface of the second connector 5 is defined as S2. When the heat dissipation hole 6 is provided in plurality, S1 refers to the total area of the plurality of heat dissipation holes 6. The larger the S1 is, the more the raw material can be saved, the cost can be reduced, and the heat dissipation effect can be increased, but the strength of the door body 2 is influenced and is easy to deform. Therefore, the relationship between the area S1 of the heat dissipation hole 6 and the outer circumferential surface area S2 of the second connector 5 can be designed appropriately to ensure the heat dissipation effect and the mechanical strength. The indexes of the heat dissipation effect and the mechanical strength are defined as A, when A is larger, the heat dissipation effect and the mechanical strength of the door body 2 are best, and when A is smaller, the structural design of the door body 2 is unreasonable. Table 1 is a relationship of ratios S1/S2 and A of S1 to S2.

TABLE 1

Fitting the data in Table 1 results in agreement between S1/S2 and A as follows: a ═ -57.588 (S1/S2)²+37.966(S1/S2)-1.6417。

When the S1/S2 is between 0.24 and 0.40, the A value is 4.15 to 4.61, which shows that the door body 2 not only has a good heat dissipation effect, but also does not influence the mechanical strength and stability; when the ratio S1/S2 is less than 0.24, the area of the heat dissipation hole 6 is small, which is beneficial to improving the mechanical strength of the door body 2, but the heat dissipation effect is poor, and is not beneficial to saving materials; when S1S 2 is greater than 0.40, louvre 6' S area is great, can provide better radiating effect, but because louvre 6 is the trompil that sets up on the door body 2, is unfavorable for the mechanical strength and the fastness of door body 2, makes door body 2 yielding and damage.
