Description

Technical Field

[0001] The utility model relates to the technical field of ovens, in particular to a rear ventilation net for a box body. Background Art

[0002] In recent years, with the improvement of people's living standards, ovens, as common appliances in household kitchens, have gradually increased in usage frequency. An oven is an electric appliance that uses radiant heat emitted by electric heating elements to bake food, and its ventilation design is generally carried out through a rear ventilation net.

[0003] At present, for the traditional rear ventilation net used in ovens, it usually has uniformly arranged ventilation holes on a plate. Although this design is simple, there are some deficiencies. For example, when the temperature inside the oven is too high, the ventilation volume cannot be effectively adjusted, resulting in difficult temperature control. When the humidity inside the oven is relatively high, the fixed ventilation holes are also difficult to effectively remove moisture, affecting the cooking quality of food. Summary of the Invention

[0004] The purpose of the utility model is to provide a rear ventilation net for a box body to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A rear ventilation net for a box body includes a rear ventilation plate and an opening degree adjusting mechanism. The rear ventilation plate is provided with uniformly distributed ventilation holes. The rear ventilation plate is connected with an opening degree adjusting mechanism. The opening degree adjusting mechanism includes a nut block, a trapezoidal screw, a connecting block, a baffle, and a sliding rod. The rear end face of the rear ventilation plate is fixedly connected with a nut block. The trapezoidal screw is threadedly connected to the nut block. The lower end of the trapezoidal screw is rotatably connected to a connecting block. The upper surface of the connecting block is fixedly connected with two symmetrically arranged sliding rods. The upper ends of the sliding rods slide through the nut block. The rear end face of the connecting block is fixedly connected with a baffle. The baffle is slidably connected to the rear end face of the rear ventilation plate, and the baffle is provided with ventilation holes matching the ventilation holes.

[0007] As a further scheme of the utility model: The rear end face of the rear ventilation plate is fixedly connected with two symmetrically arranged inverted L-shaped limiting strips. The two ends of the baffle are respectively slidably inserted into the two inverted L-shaped limiting strips.

[0008] As a further scheme of the utility model: The baffle is fixedly connected to the connecting block by screws.

[0009] As a further scheme of the utility model: The upper end of the trapezoidal screw is fixedly connected with a flower-shaped block.

[0010] As a further scheme of the utility model: Installation holes are respectively arranged at the four corners of the rear ventilation plate.

[0011] As a further solution of the utility model: an upper limit sleeve is fixedly sleeved on the upper end of the sliding rod, and a lower limit sleeve is fixedly sleeved on the lower end of the sliding rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] Through the opening degree adjusting mechanism provided by the utility model, the ventilation volume can be adjusted, avoiding the situation that the heat inside the oven rapidly loses due to excessive ventilation volume, and also avoiding the situation that the temperature inside the oven is too high due to too small ventilation volume. By appropriately adjusting the ventilation volume, the stability of the temperature inside the oven is ensured, so as to provide a better cooking effect. Secondly, different foods have different requirements for humidity. For example, bread needs a certain humidity to remain soft, while baking meat requires reducing the humidity to obtain the effect of crispy outside and tender inside. By adjusting the ventilation volume, the humidity inside the oven can be better controlled to meet the cooking requirements of different foods. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1 to 3 , in the embodiments of the present utility model, a rear ventilation net for a box body includes a rear ventilation plate 1 and an opening degree adjusting mechanism.

[0020] In the specific implementation process, such as Figure 1 , Figure 2 and Figure 3As shown, the rear ventilation plate 1 is provided with uniformly distributed ventilation holes 6. A opening degree adjusting mechanism is connected to the rear ventilation plate 1. The opening degree adjusting mechanism includes a nut block 7, a trapezoidal screw 8, a connecting block 9, a baffle 3 and a sliding rod 10. The rear end face of the rear ventilation plate 1 is fixedly connected with a nut block 7. The trapezoidal screw 8 is threadedly connected to the nut block 7. The lower end of the trapezoidal screw 8 is rotatably connected to a connecting block 9. The upper surface of the connecting block 9 is fixedly connected with two symmetrically arranged sliding rods 10. The upper ends of the sliding rods 10 slidably penetrate through the nut block 7. The rear end face of the connecting block 9 is fixedly connected with a baffle 3. The baffle 3 is slidably connected to the rear end face of the rear ventilation plate 1, and the baffle 3 is provided with ventilation holes 4 matching the ventilation holes 6.

[0021] It should be noted that: during use, the rear ventilation plate 1 is installed on the rear end face close to it. During the use of the oven, when the trapezoidal screw 8 is rotated forward, since the trapezoidal screw 8 is rotatably connected to the connecting block 9, and the connecting block 9 is restricted by the sliding rods 10, the connecting block 9 cannot rotate on its own as the trapezoidal screw 8 rotates. Thus, the rotational feed of the trapezoidal screw 8 drives the connecting block 9 to move vertically downward. The vertical downward movement of the connecting block 9 drives the baffle 3 to slide vertically downward, causing the ventilation holes 4 and the ventilation holes 6 to be gradually misaligned, and the opening degree of the ventilation holes 6 to gradually decrease. By rotating the trapezoidal screw 8 in the reverse direction, the baffle 3 can slide vertically upward, causing the ventilation holes 4 and the ventilation holes 6 to gradually align, and the opening degree of the ventilation holes 6 to gradually increase. During the adjustment process, due to the self-locking positioning of the trapezoidal screw 8, during the use of the oven, the opening degree of the ventilation holes 6 can be adjusted according to the temperature and humidity displayed on the oven, so that the ventilation volume can be adjusted, avoiding the situation where the heat inside the oven rapidly escapes due to excessive ventilation volume, and also avoiding the situation where the temperature inside the oven is too high due to too small ventilation volume. By appropriately adjusting the ventilation volume, the stability of the temperature inside the oven is ensured, thereby providing a better cooking effect. Secondly, different foods have different requirements for humidity. For example, bread needs a certain humidity to remain soft, while baking meat requires reducing the humidity to obtain the effect of being crispy on the outside and tender on the inside. By adjusting the ventilation volume, the humidity inside the oven can be better controlled to meet the cooking requirements of different foods.

[0022] Reference Figure 1 and Figure 2 As shown, two symmetrically arranged inverted L-shaped limiting strips 5 are fixedly connected to the rear end face of the rear ventilation plate 1. The two ends of the baffle 3 are respectively slidably inserted into the two inverted L-shaped limiting strips 5. By providing the inverted L-shaped limiting strips 5, the two ends of the baffle 3 are limited, making the sliding adjustment process of the baffle 3 more stable.

[0023] Reference Figure 3 As shown, the baffle 3 is fixedly connected to the connecting block 9 by screws, enabling the baffle 3 to be conveniently disassembled and assembled for easy cleaning.

[0024] Reference Figure 3 As shown, a flower-shaped block 13 is fixedly connected to the upper end of the trapezoidal screw rod 8. By providing the flower-shaped block 13, it is convenient to drive the rotation of the trapezoidal screw rod 8.

[0025] Reference Figure 1 As shown, mounting holes 2 are provided at the four corners of the rear ventilation plate 1. By providing the mounting holes 2, it is convenient to install and fix the rear ventilation plate 1.

[0026] Reference Figure 1 As shown, an upper limit sleeve 12 is fixedly sleeved on the upper end of the slide rod 10, and a lower limit sleeve 11 is fixedly sleeved on the lower end of the slide rod 10. When the baffle 3 slides downward to adjust the ventilation volume, the slide rod 10 slides downward, and finally the lower surface of the upper limit sleeve 12 abuts against the nut block 7. When the baffle 3 slides upward to adjust the ventilation volume, the slide rod 10 slides upward, and finally the upper surface of the lower limit sleeve 11 abuts against the nut block 7. During the adjustment of the ventilation volume, the upper limit sleeve 12 and the lower limit sleeve 11 play a role in limiting the up and down sliding adjustment of the baffle 3.
