Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, specifically to an auxiliary air intake structure for an integrated stove. Background Technology

[0002] With urbanization and improved living standards, integrated cooktops have gradually become common kitchen appliances in modern kitchens. However, due to the limited exhaust capacity of shared flues, the high flow rate and high power of integrated cooktops can lead to insufficient exhaust pressure. Similarly, due to various reasons, such as residents not using the flue according to regulations or poor flue design, backflow of cooking fumes may occur.

[0003] To address these issues, a patent has been proposed for an integrated cooktop that requires auxiliary exhaust. This patent incorporates separate air inlets and outlets, allowing the integrated cooktop to utilize a piston to create negative air pressure, thus aiding in the removal of cooking fumes. This structure also prevents backflow of fumes, keeping the kitchen clean and tidy. It effectively solves the problems of insufficient exhaust pressure and backflow of fumes in integrated cooktops, while improving the convenience and safety of kitchen use. This is a highly efficient and practical design that meets people's ever-evolving needs for kitchen appliances. Summary of the Invention

[0004] To address the problems existing in the prior art, this invention proposes an auxiliary air intake structure for integrated stoves.

[0005] The technical solution of the present invention is as follows:

[0006] An auxiliary air intake structure for an integrated stove includes an integrated stove body. An auxiliary smoke exhaust channel is provided inside the integrated stove body. The auxiliary smoke exhaust channel includes a vertical smoke exhaust channel and a horizontal smoke exhaust channel connected to the vertical smoke exhaust channel. A one-way suction valve module is provided inside the vertical smoke exhaust channel, and a one-way exhaust valve module is provided inside the horizontal smoke exhaust channel. The horizontal smoke exhaust channel is connected to a common flue.

[0007] Furthermore, the air inlet of the auxiliary smoke exhaust channel is located on both sides of the air inlet of the integrated stove body, and the air inlet of the auxiliary smoke exhaust channel is louvered.

[0008] Furthermore, the one-way exhaust valve module includes a wedge-shaped stop A, a spherical valve body A, a spring A, a spring washer, and a piston module. The wedge-shaped stop A is disposed on the inner wall of the vertical exhaust channel and located above the connection of the horizontal exhaust channel. The spring washer is disposed on the inner wall of the vertical exhaust channel and located below the connection of the horizontal exhaust channel. One end of the spring A is connected to the spherical valve body A, and the other end is connected to the spring washer. The piston module is disposed in the vertical exhaust channel and located below the spring washer.

[0009] Furthermore, the one-way exhaust valve module includes a spherical valve body B, a spring B, and a wedge-shaped stop block B. The wedge-shaped stop block B is disposed on the inner wall of the horizontal exhaust channel and located between the common exhaust channel and the vertical exhaust channel, and is positioned close to the side of the common exhaust channel. The spherical valve body B is disposed at the end of the horizontal exhaust channel via the spring B.

[0010] Furthermore, the auxiliary smoke exhaust channel forms a flow space between the wedge-shaped baffle A and the wedge-shaped baffle B.

[0011] Furthermore, the piston module includes a piston, a connecting rod, a crankshaft, and a fixed shaft. The fixed shaft is connected to the crankshaft, and one end of the connecting rod is connected to the piston, while the other end is connected to the crankshaft.

[0012] Furthermore, when the piston module is not working, the one-way suction valve module is subjected to the upward pressure of the spring A, and the spherical valve body A abuts against the wedge-shaped stop block A, and is in a closed state; when the piston module is working, when a negative pressure area is formed in the flow space, the spherical valve body A is subjected to the downward suction force, and is in an open state, allowing gas to flow.

[0013] Furthermore, when the piston module is not working, the pressure in the flow space is equal to that in the common flue, and the spherical valve body B is under pressure to the right, so the spring B contracts and the spherical valve body B does not contact the wedge-shaped stop block B, thus it is in the open state. When the piston module is working, a negative pressure area is formed in the flow space. At this time, the pressure in the flow space is less than that in the common flue, and the spherical valve body B is under suction to the left, thus it is in the closed state and gas cannot flow.

[0014] Furthermore, the spring washer has mesh holes, which does not affect the air communication between the piston and the flow space.

[0015] Operating steps: The range hood starts working, the piston module opens simultaneously, and the auxiliary exhaust system begins operation. The main airflow of smoke enters the fan through the air inlet and is exhausted, while a small portion of the smoke that easily escapes from the left and right sides is drawn into the auxiliary exhaust channel through the louvered air inlets on the left and right sides. Because the pressure in the auxiliary exhaust channel is lower than that in the common flue, the one-way suction valve is closed and the one-way exhaust valve is open before the piston begins its reciprocating motion.

[0016] After the piston starts working, a negative pressure area is formed in the flow space, which attracts the ball valve body A of the one-way suction module to fall and the ball valve body B of the one-way exhaust module to move to the left. At this time, the flue gas is discharged from the common flue through the reciprocating motion of the piston. In the reciprocating motion, the oil fumes are continuously sucked in and discharged. This structure can also prevent the backflow of oil fumes.

[0017] As the piston reciprocates, the fumes are periodically drawn into the circulation space and then discharged into the common flue, preventing backflow of fumes and providing auxiliary airflow for the integrated stove to operate.

[0018] The beneficial effects of this invention are as follows:

[0019] 1) The auxiliary exhaust device can alleviate the problem of high smoke exhaust resistance in the public flue during peak smoke exhaust periods in residential buildings by improving the air extraction capacity.

[0020] 2) When the integrated stove is not working, the piston can be turned on separately to activate the induced ventilation with a small amount of electricity, which can effectively alleviate the problems of backflow of oil fumes and kitchen odors.

[0021] 3) The one-way valve in the channel consists of a ball valve body and a spring. When working, it only changes the compression and relaxation state by pressure. Unlike the structure of ordinary check valves, it avoids the problem of valve body deformation and deterioration of effect after long-term use of ordinary check valves. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] like Figures 1 to 5 As shown, an auxiliary air intake structure for an integrated stove is provided. The main body 1 of the integrated stove is rectangular in shape. The air inlet 11 of the integrated stove is located in the center position as shown in the figure. The auxiliary smoke exhaust channel inlet 21 is located on the left and right sides. The auxiliary smoke exhaust channel inlet 21 is designed as a louvered type to prevent foreign objects from entering and damaging the device.

[0030] The auxiliary exhaust duct 2 is placed vertically inside the integrated stove, and its outlet connects to the common exhaust duct 4.

[0031] Auxiliary smoke exhaust duct 2 includes a vertical smoke exhaust duct and a horizontal smoke exhaust duct connected to the vertical smoke exhaust duct;

[0032] The auxiliary smoke exhaust channel 2 is equipped with a one-way extraction valve module 5, a one-way exhaust valve module 6, and a piston module 7.

[0033] The one-way exhaust valve module 5 is vertically installed in the vertical smoke exhaust channel and includes a wedge-shaped stop A51, a ball valve body A52, a spring A53 and a spring washer 54; the one-way exhaust valve module 6 is horizontally installed in the horizontal smoke exhaust channel and includes a ball valve body B61, a spring B62 and a wedge-shaped stop B63; the piston module 7 is composed of a piston 71, a connecting rod 72, a crankshaft 73 and a fixed shaft 74, and the piston module 7 is equipped with a power unit.

[0034] The gas space within the auxiliary smoke exhaust duct 2 is divided into two parts: a circulation space 8 and a common flue 4. When the one-way exhaust valve module 5 is closed, the circulation space 8 and the common flue 4 are connected; when the one-way exhaust valve module 6 is closed, the circulation space 8 and the common flue 4 are separated.

[0035] The diameter of the auxiliary smoke exhaust duct should be specified to be within 40-55mm, and can be adjusted within this range according to the specific size of the integrated stove.

[0036] Operating Steps: When the integrated stove is turned on, the main airflow of fumes is discharged to the common flue 4 by the fan 3. At the same time, the piston module 7 starts to discharge the remaining fumes into the common flue 4 through the auxiliary exhaust channel 2. Under normal circumstances, the pressure inside the common flue 4 is greater than that outside, so the ball valve body A52 of the one-way suction valve module 5 is subjected to upward pressure and is in a closed state. Conversely, the one-way exhaust valve module 6 is subjected to rightward pressure and is in an open state (the pressure in the circulation space is equal to that in the common flue). When the piston module 7 moves and creates a negative pressure area, the one-way suction valve module 5 receives downward suction and is in an open state, at which point the fumes are drawn into the circulation space 8. Meanwhile, the one-way exhaust valve module 6 receives leftward suction and is in a closed state. After the piston module 8 completes one reciprocating motion, it returns to the normal state. At this time, the circulation space 8 and the common flue 4 are connected again, and the fumes are discharged into the common flue 4.

[0037] Through the above working steps, the auxiliary smoke exhaust channel 2 completes its auxiliary smoke exhaust function. At the same time, this mechanical structure is different from the check valve, and its structure will not be damaged due to working time. Furthermore, the auxiliary smoke exhaust helps high-rise users avoid the problem of insufficient smoke exhaust pressure during peak cooking periods. The auxiliary smoke exhaust function can also be activated independently when cooking is not in use. Through the above working steps, ventilation is induced, preventing the backflow of oil fumes from the public exhaust duct into the home and preventing the occurrence of oil fume backflow problems.
