Description

Technical Field

[0001] This utility model relates to the field of integrated stoves, and in particular to an integrated stove capable of bidirectional exhaust of cooking fumes. Background Technology

[0002] The existing integrated cooktop structure includes a main body, a smoke chamber, an air duct, a fan, and an oil box. The fan connects the smoke chamber and the air duct. The air duct is horizontally located at the rear of the main body, with the smoke chamber directly above it and the oil box directly below it. The rear end of the oil box is connected to a ventilation duct. An exhaust vent is located at the rear of the main body, connecting to an exhaust pipe that leads to the outside, thus expelling the cooking fumes outdoors. However, this design does not allow for adjustment of the airflow direction as needed.

[0003] Research revealed that current integrated cooktop designs that allow for fume extraction from either the left or right side require modifications to the fan. The fan needs to be modified to allow for dual-direction airflow, requiring an additional vertical pipe connected to the fume chamber at the top and the ventilation fan at the bottom. However, this increases the internal space occupied by the vertical pipe, especially vertically. Furthermore, modifications to the fan structure are costly. Additionally, separate oil collection cups are needed for both vertical and horizontal fans, complicating the design. Currently, only single-direction fume extraction is possible; simultaneous extraction from both sides requires rotating the fan to adjust the airflow direction. For example, when the fan outlet is aimed at the left side of the cooktop, it needs to be rotated to aim at the right side. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated stove that can exhaust oil fumes in both directions without the need to modify the fan. It has a compact structure, facilitates oil connection to the fan, and simplifies the structure. It can exhaust oil fumes from both the left and right sides simultaneously without the need to flip the fan to adjust the airflow direction.

[0005] To achieve this objective, the present invention adopts the following technical solution: an integrated stove capable of bidirectional fume extraction, comprising an integrated stove body, a smoke chamber, an air duct, a fan, and an oil box, wherein the fan connects the smoke chamber and the air duct; the air duct is horizontally located at the rear of the integrated stove body, the smoke chamber is located directly above the air duct, the oil box is located directly below the air duct, and the rear end of the oil box is connected to the ventilation duct; the air duct is a straight pipe structure, and the integrated stove body has one fume extraction opening on each of the left and right sides of the air duct; the fan is located directly in front of the air duct, the fan outlet is connected to the middle of the ventilation duct, and the fan inlet faces upward and connects to the bottom of the smoke chamber; the bottom of the fan connects to the front end of the oil box.

[0006] Firstly, this product achieves the effect of venting oil fumes from both sides of the integrated stove through an air duct. Specifically, an exhaust opening is designed on each side of the air duct. Closing the left exhaust opening allows oil fumes to escape from the right exhaust opening; conversely, closing the right exhaust opening allows oil fumes to escape from the left exhaust opening. Opening both exhaust openings allows oil fumes to escape from both sides simultaneously, increasing the exhaust volume. Furthermore, this process does not require rotating the fan to adjust the airflow direction. Moreover, this design does not require altering the existing fan structure; the existing fan can be directly installed in front of the air duct, resulting in low modification costs.

[0007] The air duct has a straight pipe structure, with the fan located in front of the air duct. The fan connects the smoke chamber and the air duct, resulting in a compact air duct structure that does not occupy the internal space of the integrated stove body, especially not the vertical space.

[0008] In addition, the bottom of the fan is connected to the front of the oil box, so the oil inside the fan will flow directly into the oil box, thus eliminating the need to design an oil collection structure on the fan, which simplifies the product structure.

[0009] Furthermore, it also includes a stovetop, with the fan located below it. An auxiliary plate is installed below the stovetop, forming a horizontal auxiliary channel at the fan inlet. This auxiliary channel connects to the bottom of the rear smoke chamber, and its front end connects to the fan inlet. This design has a simple structure and good airflow.

[0010] The beneficial effects of this utility model are as follows: This product does not require modification of the existing fan. It can use the existing straight pipe body to achieve selective exhaust of oil fumes on the left and right sides of the integrated stove body, or exhaust oil fumes on the left and right sides of the integrated stove body at the same time, without the need to flip the fan to adjust the air outlet direction; moreover, there is no need to set up a vertical pipe, and the air duct reduces the space occupied in the integrated stove body, especially the space occupied in the vertical direction; in addition, the oil sludge of the fan can flow directly into the oil box, eliminating the need to design an oil collection structure on the fan, thus simplifying the product structure.

[0020] like Figure 1-5 As shown, an integrated stove with bidirectional fume extraction includes a main body 1, a fume chamber 2, an air duct 3, a fan 4, an oil box 5, and a cooktop 6. The fan 4 connects the fume chamber 2 and the air duct 3. The air duct 3 is located at the rear of the main body 1, the fume chamber 2 is located directly above the air duct 3, and the oil box 5 is located directly below the air duct 3. The rear end of the oil box 5 is connected to the ventilation duct 3. The cooktop 6 is equipped with cooktop appliances. This part of the structure is similar to the existing integrated stove structure and will not be described in detail here.

[0021] The improved structure of this product is as follows: Figure 1 As shown, the air duct 3 is a straight pipe structure. The straight pipe structure can be selected from existing products. The air duct 3 is installed at the bottom rear of the integrated stove body 1. The integrated stove body 1 has a fume exhaust opening 11 on each side of the air duct 3, that is, the left side of the integrated stove body 1 has a left fume exhaust opening, and the right side of the integrated stove body 1 has a right fume exhaust opening.

[0022] The fan 4 is located directly in front of the air duct 3. This fan 4 is a standard fan used in integrated stoves. The air outlet of the fan 4 connects to the center of the front of the air duct 3, meaning there is a mounting port in the center of the front of the air duct 3. The mounting port of the fan forms a flange, which is fixed to the mounting port with screws. The air inlet of the fan 4 faces upwards and connects to the bottom of the smoke chamber 2. The fan 4 is located directly above the front end of the oil box 2, and its bottom connects to the front end of the oil box 5.

[0023] The fan 4 is located below the stove 6. An auxiliary plate 61 is provided below the stove 6. The auxiliary plate 61 forms a horizontal auxiliary channel at the air inlet of the fan 4. The auxiliary channel connects to the bottom of the smoke chamber 2. The auxiliary channel is a rectangular channel that runs from front to back. The front end of the rectangular channel is connected to the air inlet of the fan 4, and the rear end of the rectangular channel is connected to the bottom of the smoke chamber 2.

[0024] Usage: Start the fan 4. The fan 4 will rotate, drawing the fumes from the smoke chamber 2 into the auxiliary channel, and then through the fan 4 into the duct 3. To exhaust fumes from the left side, simply close the exhaust opening on the right side of the integrated stove. The fumes in the duct 3 will then be exhausted from the left exhaust opening. Conversely, to exhaust fumes from the right side, simply close the exhaust opening on the left side of the integrated stove. The fumes in the duct 3 will then be exhausted from the right exhaust opening. To increase the exhaust volume by exhausting fumes from both sides simultaneously, open the exhaust openings on both sides of the integrated stove body 1. The fumes in the duct 3 can then be exhausted from the exhaust openings on both sides of the integrated stove body 1 simultaneously, thus achieving the bidirectional exhaust function of this product. Moreover, there is no need to adjust the rotation direction of the fan, making it more convenient to use.

[0025] The structure for closing the exhaust vents on both sides of the integrated stove body 1 can be designed as needed. In this embodiment, a flange is provided at each exhaust vent. This product is equipped with two rectangular plates, the area of ​​which is larger than the area of ​​the exhaust vent. The rectangular plates can cover the exhaust vents. Each rectangular plate is aligned with a flange. The flange is fixed to the outside of the rectangular plate with screws, which makes disassembly convenient. It is also best to press a sealing ring between the rectangular plate and the flange to improve the sealing effect.

[0026] This design allows the fumes to impact the inner wall of the duct 3 when they enter, making it easier for the oil to adhere to the inner wall of the duct 3 and then enter the oil box 5 through the opening at the bottom of the duct 3. At the same time, the oil in the fan 4 will flow into the oil box 5 through the gap at the shaft of the fan 4, thus achieving oil collection.

[0027] Finally, it is best to install an arc-shaped recess on the rear side wall of the air duct 3, directly opposite the air outlet of the fan 4. This recess can buffer the impact of oil fumes, thereby reducing noise, while increasing the contact surface of oil stains and improving the oil stain adsorption effect. Moreover, sound-absorbing cotton or oil-absorbing cotton can be installed inside the arc-shaped recess as needed. The sound-absorbing cotton can absorb sound, and the oil-absorbing cotton can further improve the oil stain adsorption effect.

[0028] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
