Description

Technical Field

[0001] This utility model relates to the field of kitchen fan technology, specifically a kitchen fan with intelligent control function. Background Technology

[0002] In modern family kitchens, kitchen fans are indispensable equipment, playing a crucial role in removing cooking fumes and odors and maintaining fresh air. The large amounts of cooking fumes produced not only adhere to kitchen walls, cabinets, and appliance surfaces, making them difficult to clean and affecting the kitchen's aesthetics, but also contain various harmful substances that can damage health with prolonged inhalation. Simultaneously, if odors generated during cooking are not promptly removed, they will permeate the entire living space with unpleasant smells, reducing living comfort.

[0003] For example, Chinese utility model patent application number 202221989929.8 discloses a kitchen fan with intelligent control function, which can automatically adjust itself according to different oil fume filtration requirements, thereby adapting to different oil fume emission needs. The distance between the inner and outer grid plates gradually decreases from the bottom to the top, which is beneficial for the fan to absorb oil fumes at the bottom of the fume source and prevent the fume from spreading. It is also equipped with a smoke height sensor to detect the height of the oil fume source, which allows the fan to adjust the opening position according to the height of the oil fume source, thus improving the accuracy of oil fume absorption and extraction. However, this device still has certain shortcomings.

[0004] As a high-frequency place for gas use, the kitchen is always at risk of gas leaks. Once a gas leak occurs, the leaked gas will quickly accumulate in the kitchen space and reach a certain concentration in a short period of time. Existing kitchen fans lack the ability to monitor gas leaks, so they cannot detect this dangerous situation in time, let alone take any countermeasures.

[0005] Therefore, we propose a kitchen fan with intelligent control function to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a kitchen fan with intelligent control function to solve the problem mentioned in the background art that current kitchen fans on the market lack the ability to monitor gas leaks, cannot detect dangerous gas leaks in time, and cannot take any countermeasures.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a kitchen fan with intelligent control function, including a fixed box and a smoke bucket. The smoke bucket is installed below the fixed box, and a control panel is installed on the smoke bucket. An oil fume filter is installed below the smoke bucket. A smoke sensor and a gas sensor are installed sequentially from left to right on the front surface of the smoke bucket. An oil fume collecting frame is installed below the oil fume collecting frame, and positioning bent rods are installed on the left and right sides inside the oil collecting frame.

[0008] A water tank is installed on the lower right side of the smoking pipe via a connecting block, and an atomizing nozzle is installed on the lower surface of the water tank.

[0009] Preferably, a check valve flue is installed above the fixed box, and the check valve flue has a telescopic structure design.

[0010] With the above structural design, the extracted fumes are discharged through the backflow preventer pipe to prevent backflow of fumes.

[0011] Preferably, an alarm is installed on the front surface of the smoking pipe, and the alarm is connected to a PLC controller. The PLC controller is connected to a smoke sensor, a gas sensor, and the kitchen fan body.

[0012] With the above structural design, the smoke sensor and gas sensor continuously monitor the air in the kitchen. The smoke sensor detects the concentration of smoke in the air, while the gas sensor detects the concentration of harmful gases such as gas. When the smoke sensor detects that the smoke concentration exceeds the preset value, or when the gas sensor detects a leak of harmful gases such as gas and the concentration reaches the alarm threshold, it will transmit a signal to the connected PLC controller. After receiving the signal, the PLC controller will, on the one hand, control the alarm to sound an alarm to remind people in the kitchen to pay attention to safety, and on the other hand, start the kitchen fan to increase the ventilation force and remove the smoke and gas in the kitchen as soon as possible.

[0013] Preferably, a connecting piece is installed on the lower surface of the fume filter, and a through groove is provided in the middle of the connecting piece. Fixing blocks are installed on both the left and right sides of the lower surface of the connecting piece, and through holes are provided on the fixing blocks. The positioning bent rod passes through the through holes.

[0014] With the above structural design, the smoke filter is responsible for collecting oil fumes and odors in the kitchen. When the oil fumes pass through the smoke filter, the oil is filtered down and flows into the oil receiving frame through the through groove in the middle of the connecting piece. The positioning bent rods on the left and right sides of the oil receiving frame pass through the through holes on the fixing block to realize the connection between the oil receiving frame and the connecting piece, which facilitates the disassembly and cleaning of the oil receiving frame.

[0015] Preferably, a small motor is installed on the lower right side of the smoking pipe. The small motor is connected to the PLC controller, and a connecting shaft is installed below the small motor via an output shaft. A baffle is installed below the connecting shaft. The baffle has an inclined structure design and is located below the atomizing nozzle.

[0016] With the above structural design, when the smoke sensor detects a large amount of smoke and a potential fire, in addition to increasing the ventilation of the kitchen fan, the PLC controller will start and control a small motor and open the pressure pump and control valve. The output shaft of the small motor drives the connecting shaft to rotate, and the baffle below the connecting shaft will rotate accordingly, moving the baffle away from the atomizing nozzle. Under the action of the pressure pump at the water source, water in the water tank will be sprayed out through the atomizing nozzle, playing an auxiliary role in fire fighting.

[0017] Preferably, a connecting pipe is installed above the water tank, and a control valve is installed on the connecting pipe. The water tank is connected to a water source, and a pressure pump is installed at the water source.

[0018] With the above structural design, the pressure pump delivers water from the water source to the water tank, and then the water is delivered from the water tank to the atomizing nozzle for spraying.

[0019] Preferably, a connecting slider is installed on the rear side of the smoking pipe, and positioning bolts are installed on both the left and right sides of the front surface of the connecting slider. A fixed slide rail is installed on the connecting slider.

The first slide groove and the second slide groove are connected. Positioning grooves are opened at equal intervals on the rear side of the fixed slide rail. The positioning bolts are engaged with the positioning grooves, and the positioning bolts are slidably connected to the connecting slider.

[0020] With the above structural design, the installation position of the fan can be adjusted according to actual needs. The connecting slider on the rear side of the smoke bucket is installed on the fixed slide rail. By loosening the positioning bolt, the connecting slider can slide in the first slide groove and the second slide groove. After adjusting to the appropriate position, tighten the positioning bolt to make it engage with the positioning groove, thereby fixing the position of the fan.

[0021] Compared with the prior art, the beneficial effects of this utility model are: the kitchen fan with intelligent control function:

[0022] 1. Equipped with smoke and gas sensors, the system can monitor the concentration of smoke and gas in the kitchen in real time.
