Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to an ascending hidden range hood. Background Art

[0002] A range hood, also known as a smoke extractor, is a kitchen appliance that purifies the kitchen environment. Installed above the kitchen stove, it quickly extracts waste from stove combustion and harmful cooking fumes, exhausting them outdoors. It also condenses and collects the fumes, reducing pollution, purifying the air, and providing safety features like anti-toxicity and explosion protection.

[0003] To avoid spatial interference with users, such as head collisions, top-exhaust range hoods are typically installed at a higher position, resulting in a higher intake vent, which in turn affects the efficiency of fume extraction. Many models currently on the market feature tilted panels. While this improves space utilization to some extent, the intake vent still falls short of the ideal height. Furthermore, the head panels of existing range hoods are often exposed to the elements, which can easily generate fume odors and cause reverse airflow due to external wind pressure. They also require frequent cleaning when not in use, otherwise they will affect the cleanliness of the kitchen environment. Utility Model Content

[0024] The present invention provides a kind of ascending hidden range hood. Figure 1-4 As shown, it is installed in the cabinet above the stove: Example 1: it includes a range hood body 1 and a lifting smoke hood 2, the range hood body 1 contains a fan assembly 3, and the lifting smoke hood 2 is provided with a smoke outlet 4. The range hood body 1 and the lifting smoke hood 2 form a smoke exhaust channel, and negative pressure is formed under the action of the fan assembly 3 to discharge the smoke from the smoke outlet 4 through the upper end of the smoke exhaust channel. The range hood body 1 is installed in the cabinet, and a lifting mechanism is provided in the range hood body 1, which is connected to the lifting smoke hood 2 to drive the lifting smoke hood 2 to rise and fall on the range hood body 1.

[0025] Preferably, the lifting mechanism includes a lifting DC motor 5, a transmission rod 6, a gear box 7, a lifting screw assembly 8, and a nut 9. The output end of the lifting DC motor 5 is connected to the transmission rod 6, and the two end surfaces of the transmission rod 6 are engaged with the upper end of the lifting screw assembly 8. The gear box 7 is connected to the transmission rod 6 to stabilize the entire rotation process of the transmission rod 6. The nut 9 is connected to the lifting screw assembly 8 through a thread. The lifting smoke hood 2 is arranged on the nut 9. The rotation of the screw in the lifting screw assembly 8 drives the nut 9 to realize the lifting of the smoke hood. The lifting DC motor 5 is connected to the main electronic control board on the range hood body 1 through a circuit.

[0026] Preferably, it also includes a main electrical control board arranged in the range hood body 1, a touch switch 10 is provided on the lifting smoke hood 2, and a mechanical switch 11 is provided on the range hood body 1, the touch switch 10 and the mechanical switch 11 are electrically connected to the main electrical control board, and the fan assembly 3 and the lifting DC motor 5 are connected to the fan main electrical control board through lines.

[0027] Further, such as Figure 1 As shown, two pairs of left and right slide rail groups are provided in the range hood body 1, and the slide rail group includes an outer slide rail 12 and an inner slide rail 13. The outer slide rail 12 is provided on the inner side of the outer wall of the range hood body 1, and the inner slide rail 13 is provided on the side wall of the fan box.

[0028] Example 2: Figure 2-3 As shown, preferably, the smoke outlet 4 is provided with a flip plate 14, and the inner side of the lifting smoke hood 2 is provided with a flip mechanism, and the flip mechanism drives the flip plate 14 to open and close, opening or closing the smoke outlet 4, and the air suction port of the lifting smoke hood 2 is provided with a movable flip plate 14. When the lifting smoke hood 2 is in the operation of sucking and exhausting oil smoke, the flip plate 14 is opened to form an effective barrier to the upstream oil smoke, and the oil smoke is diverted into the smoke outlet 4, which is beneficial to improving the effect of sucking oil smoke.

[0029] Specifically, the flip mechanism includes a push rod 15 and a connecting rod group. The connecting rod group includes an upper connecting rod 16 and a lower connecting rod 17. The lower end of the lower connecting rod 17 is connected to the flip plate 14, the upper end is hinged to the upper connecting rod 16, and the middle is hinged to the inner side of the lifting smoke hood 2. The body of the push rod 15 is arranged in the lifting smoke hood 2, and the protruding end of the push rod 15 is hinged to the upper connecting rod 16.

[0030] Further preferably, the number of the flip cover plates 14 is two, and they are provided on the left and right sides of the smoking port 4, which are opened and closed by a push rod 15 alone. When one side of the stove eye is opened, the corresponding air outlet can be selected to be flipped up to meet the diverse needs of customers.

[0031] Working principle: When the ascending hidden range hood is in use, the lifting DC motor 5 is connected to the transmission rod 6 in the horizontal position, and the transmission rod 6 in the horizontal position is connected to the vertical lifting screw rod. The lifting DC motor 5 drives the transmission rod 6 to rotate, and then the transmission rod 6 drives the screw rod in the lifting screw rod assembly 8 to rotate. The gear box 7 is connected to the position of one-third of the total length of the transmission rod 6, and its function is to stabilize the entire rotation process of the transmission rod 6 (because the transmission rod 6 is too long and will be deformed, affecting the transmission smoothness and life). The nut 9 is connected to the lifting screw rod assembly 8 through a thread. The lifting smoke hood 2 is set on the nut 9. The rotation of the screw rod in the lifting screw rod assembly 8 drives the nut 9 to realize the lifting of the smoke hood.

[0032] After the smoke hood 2 is lifted and extended out of the range hood body 1, the push rod 15 is started, and the push rod 15 pushes the connecting rod group, driving the flip plate 14 to open the oil suction port, and then the fan assembly 3 is started. The fan assembly 3 forms a negative pressure in the range hood body 1, and the oil is sucked into the smoke outlet 4. The setting of the flip plate 14 also plays a good wind-guiding role, so that the oil smoke is blocked by the flip plate 14 upward, smoothly enters the smoke outlet 4, and is discharged from the upper end of the range hood body 1 through the smoke exhaust channel.

[0033] In summary,

[0034] The lifting type hidden range hood has a lifting smoke collection hood 2 that can be lifted and lowered intelligently, and the structure of the synchronous double lifting screws and double guide rails can make the lifting smoke collection hood 2 more stable, balanced left and right, and avoid swinging. When opened, the lifting smoke collection hood 2 can be lowered to absorb and exhaust oil smoke, and when closed, it can be raised and hidden, ensuring a clean environment in the kitchen and avoiding unnecessary occupation of the space above the stove.

[0035] The ascending hidden range hood has a movable flap 14 at the air intake of the lifting smoke collecting hood 2. When the lifting smoke collecting hood 2 is in operation for extracting and discharging oil smoke, the flap 14 opens to effectively block the upward oil smoke and guide the oil smoke into the suction port 4, thereby improving the effect of extracting oil smoke.

[0036] The rising hidden range hood has a movable flip cover 14 provided in two parts, the opening and closing of which are controlled by a push rod 15 alone. When one side of the stove eye is turned on, the corresponding air outlet can be flipped up to meet the diverse needs of customers.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
