Description

Technical Field

[0001] This utility model belongs to the field of range hood technology, specifically relating to a range hood with air conditioning and fresh air supply. Background Technology

[0002] Commercial range hoods are highly efficient smoke extraction and purification devices designed specifically for commercial kitchens. Their core function is to quickly remove large amounts of oil fumes, odors, and harmful gases generated during cooking, while reducing environmental pollution through purification technology, protecting the health of kitchen staff, and meeting national environmental protection and safety standards.

[0003] Kitchen air conditioners, as standalone units, take up space. Therefore, some people have come up with the idea of ​​designing kitchen air conditioners and range hoods as one unit, adding a compressor, condenser, evaporator, blower and other structures inside the range hood to combine the functions of air conditioning fresh air and fume extraction.

[0004] For example, in the prior art, Chinese utility model patent with authorization announcement number CN222317186U discloses "a kitchen air conditioning device and its integrated kitchen air conditioning and range hood", which includes a cabinet assembly and a fan, evaporator, condenser and compressor disposed in the cabinet assembly. The cabinet assembly includes a first cabinet and a second cabinet disposed on the left and right, and an accommodating space is formed between the first cabinet and the second cabinet. The accommodating space is used to accommodate the air duct module of the range hood.

[0005] While existing air conditioning and range hood systems, including those mentioned above, can meet general usage scenarios, they lack a fresh air guide device. Air is discharged horizontally from the air outlet, resulting in large dead zones in airflow coverage (such as corners of walls and behind furniture), and they are also prone to blowing directly on workers, which greatly limits their use.

[0006] To address the aforementioned problems, this utility model proposes a range hood with air conditioning and fresh air supply. Utility Model Content

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] Please see Figures 1-5The present invention provides the following technical solution: a range hood with air conditioning and fresh air, comprising a range hood body 1, a base plate 2 fixed to the bottom of the range hood body 1, and an air conditioning and fresh air assembly 3 fixed to the top of the range hood body 1. The air conditioning and fresh air assembly 3 includes: an outer shell 31 fixed to the top of the range hood body 1, a duct 32 fixed inside the range hood body 1 and communicating with the outer shell 31, an exhaust head 33 fixed to the bottom of the base plate 2 and communicating with the duct 32, a baffle plate 34, a drive mechanism 35, and a filter mechanism 36.

[0050] Furthermore, by Figure 1 and Figure 2 As shown, in this embodiment, an air inlet 311 is provided at the top of the outer shell 31, the bottom surface of the exhaust head 33 is inclined, and an air outlet 331 is provided on the inclined surface. Multiple baffles 34 are rotatably installed in the air outlet 331. A drive mechanism 35 is used to drive the baffles 34 to rotate. A filter mechanism 36 is slidably installed in the outer shell 31 near the air inlet 311.

[0051] This utility model further includes a blower 4, a compressor 5, a throttle valve 6, a condenser 7, an evaporator 8, and a laser dust sensor 9. The compressor 5, the throttle valve 6, the condenser 7, and the evaporator 8 form a closed loop using a flexible hose and are integrated and installed inside the housing 31. The blower 4 is installed inside the housing 31 and faces the evaporator 8. The laser dust sensor 9 is fixed inside the flue of the range hood body 1 and is connected to the blower 4 for signal transmission. With the above solution, when in use, the air inlet 311 is connected to the outside through a pipe to introduce air from the outside. When the blower 4 is started, fresh outside air enters the air conditioning fresh air assembly 3 from the air inlet 311 at the top of the housing 31. It first passes through the filter mechanism 36 to filter out dust, impurities, and other pollutants in the air, ensuring that the air entering the room is clean.

[0052] Compressor 5 compresses the refrigerant into a high-temperature, high-pressure gas, which is then sent to condenser 7. Condenser 7 releases heat to the outside, and the refrigerant liquefies into a high-pressure liquid. The liquid is depressurized by throttle valve 6 and enters evaporator 8, where it evaporates and absorbs heat, causing the surface temperature of evaporator 8 to decrease. The evaporated refrigerant gas returns to compressor 5, and the cycle repeats.

[0053] Blower 4 is installed directly opposite evaporator 8. After starting, it forces the filtered air to pass through evaporator 8. Due to the low temperature of the surface of evaporator 8, the air exchanges heat with evaporator 8, and the temperature drops (achieving the cooling function), forming cool fresh air.

[0054] Based on existing technology, it is easy to understand that, if necessary, by switching the refrigerant flow direction (such as by connecting a four-way reversing valve, not shown), the high-temperature and high-pressure refrigerant gas discharged from the compressor 5 will no longer enter the condenser 7, but will enter the evaporator 8, so that the condenser 7, which was originally used for heat dissipation, becomes the heat absorption end and the evaporator 8 becomes the heat release end, thus realizing the heating function.

[0055] The cooled air is introduced into the main body of the range hood 1 from the outer shell 31 through the air duct 32, and then discharged through the exhaust head 33 at the bottom of the base plate 2.

[0056] The spoiler 34 is rotatably installed inside the air outlet 331, and its angle is controlled by the drive mechanism 35. By adjusting the tilt direction of the spoiler 34, the air outlet angle and diffusion range of the fresh air can be changed to achieve directional air supply or wide-angle air supply, improve the air circulation efficiency in the kitchen, and effectively avoid direct airflow from interfering with cooking operations.

[0057] The laser dust sensor 9 monitors the concentration of oil fumes and the content of dust particles, and transmits the data to the control system of the range hood. For example, when the laser dust sensor 9 detects an increase in the concentration of oil fumes in the flue, it will automatically send a signal to the blower 4 to increase its speed and speed up the delivery of fresh air. Conversely, when there are fewer oil fumes, the blower 4 will reduce its speed or temporarily shut down to save energy.

[0058] It should be noted that the internal structure and working principle of the range hood body 1 are all publicly available technologies. For details, please refer to the existing range hood technologies. This article will not elaborate further.

[0059] Optionally, by Figures 1-3 As shown, in this embodiment, the drive mechanism 35 includes: a mounting shaft 351, a gear 352, a rack 353, a moving plate 354, a fixed plate 355, and an electric push rod 356. The mounting shaft 351 is fixed to the end of the spoiler 34 and connected to the exhaust head 33 to form a rotating structure. The gear 352 is fixed on the mounting shaft 351. The rack 353 is slidably connected to the exhaust head 33 and meshes with the gear 352. The moving plate 354 is fixed to the outer wall of the rack 353. The fixed plate 355 is fixed to the outer wall of the exhaust head 33. The electric push rod 356 is fixed to the outer wall of the fixed plate 355 and the electric push rod 356 is also fixed to the outer wall of the fixed plate 355. The piston rod of rod 356 passes through the fixed plate 355 and is fixedly connected to the movable plate 354. With the above scheme, when it is necessary to adjust the angle of the spoiler 34, the electric push rod 356 is activated. The electric push rod 356 pushes the movable plate 354, which drives the rack 353 fixedly connected to the movable plate 354 to slide on the exhaust head 33. The rack 353 meshes with the gear 352 fixed on the mounting shaft 351. The linear motion of the rack 353 is converted into the rotation of the gear 352, thereby causing the mounting shaft 351 to rotate, and finally realizing the rotation of the spoiler 34.

[0060] By controlling the extension and retraction length of the piston rod of the electric push rod 356, the sliding distance of the rack 353 can be precisely controlled, thereby precisely controlling the rotation angle of the gear 352, and finally achieving precise adjustment of the rotation angle of the spoiler 34 to meet different air outlet requirements.

[0061] Preferably, by Figures 1-3 As shown, in this embodiment, the drive mechanism 35 further includes two guide rods 357. The two guide rods 357 are symmetrically fixed to the outer wall of the moving plate 354 and pass through the fixed plate 355. With the above solution, when the moving plate 354 moves under the push of the electric push rod 356, the guide rods 357 will move linearly along the through holes on the fixed plate 355. Since the guide rods 357 are symmetrically arranged, they can restrict the moving plate 354 to move only along the axial direction of the guide rods 357, avoiding the moving plate 354 from deviating, shaking or tilting during the movement, ensuring the accuracy of the movement direction of the moving plate 354, thereby improving the stability of the rack 353.

[0062] Preferably, by Figures 1-3 As shown in this embodiment, the drive mechanism 35 further includes a guide slider 358 and a stop block 359. The guide slider 358 is fixed to the outer wall of the exhaust head 33, and a guide sliding hole 3531 for the guide slider 358 to pass through is provided on the rack 353. The stop block 359 is fixed to the protruding end of the guide slider 358. With the above solution, when in use, the guide sliding hole 3531 cooperates with the guide slider 358 to further restrict the movement direction of the rack 353, and cooperates with the stop block 359 to limit the rack 353 from the outside, further improving the stability of the rack 353 and preventing the rack 353 from deviating, shaking or tilting during movement.

[0063] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the filtration mechanism 36 includes: two frames 361, a HEPA filter 362, an activated carbon filter 363, a limiting baffle 364, and bolts 365. The two frames 361 are distributed vertically at intervals, and a disassembly port 312 for the frames 361 to pass through is provided on the outer shell 31. The HEPA filter 362 is fixed in the upper frame 361, the activated carbon filter 363 is fixed in the lower frame 361, the limiting baffle 364 is fixed at one end of the frame 361, and the bolts 365 pass through the limiting baffle 364 and are threadedly connected to the outer shell 31. With the above solution, when air enters, it first passes through the HEPA filter 362 in the upper frame 361. The HEPA filter 362 has high-efficiency filtration performance and can effectively intercept small particles in the air, such as dust, pollen, smoke, bacteria, and viruses, to achieve preliminary air purification.

[0064] After being filtered by the HEPA filter 362, the air then passes through the activated carbon filter 363 located in the lower frame 361. The activated carbon filter 363 has a rich microporous structure and a large specific surface area, which can adsorb harmful gases in the air, such as formaldehyde, benzene, sulfur dioxide, ammonia and other volatile organic compounds, as well as odor molecules, further purifying the air.

[0065] The air, after being filtered twice by HEPA filter 362 and activated carbon filter 363, becomes cleaner and then continues to flow within the air conditioning fresh air component 3.

[0066] When it is necessary to replace the HEPA filter 362 or the activated carbon filter 363, simply unscrew the bolt 365 to separate the limiting baffle 364 from the housing 31, and then the frame 361 can be pulled out from the disassembly port 312 for easy replacement or cleaning of the HEPA filter 362 and the activated carbon filter 363.

[0067] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown in this embodiment, the filter mechanism 36 further includes a U-shaped insert frame 366, which is fixed inside the outer shell 31 at the position corresponding to the disassembly port 312, and a slot 3661 for the frame 361 to be inserted is provided in the U-shaped insert frame 366. With the above solution, when in use, the slot 3661 of the U-shaped insert frame 366 forms a positioning and stable support for the frame 361, realizing the sliding installation of the frame 361, which facilitates the installation and disassembly of the frame 361.

[0068] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown in this embodiment, the filter mechanism 36 further includes a handle 3641, which is fixed to the outer wall of the limiting baffle 364. With the above solution, when in use, the handle 3641 can be used to apply force and pull out the frame 361.

[0069] It should be noted that the electric actuator 356, blower 4, compressor 5, throttle valve 6, condenser 7, evaporator 8, and laser dust sensor 9 are all commercially available conventional equipment. Those skilled in the art can make conventional selections according to their needs. Their working principles are common knowledge known to those skilled in the art and have been fully disclosed in the prior art, so they will not be elaborated on further in this article.

[0070] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0071] Components not described in detail in this article are existing technologies.

[0072] The working principle and usage process of this utility model: When using the range hood of this utility model, the air inlet 311 is connected to the outside through a pipe to introduce air from the outside. When the blower 4 is started, the fresh air from the outside enters the air conditioning fresh air component 3 from the air inlet 311 at the top of the outer shell 31. It first passes through the HEPA filter 362 located in the upper frame 361, which can effectively intercept tiny particles in the air and achieve preliminary purification of the air.

[0073] After being filtered by the HEPA filter 362, the air then passes through the activated carbon filter 363 located in the lower frame 361. The activated carbon filter 363 has a large specific surface area and can adsorb harmful gases in the air, further purifying the air.

[0074] Blower 4 is installed directly opposite evaporator 8. After starting, it forces filtered air to pass through evaporator 8. Due to the low temperature of evaporator 8, the air exchanges heat with evaporator 8, and the temperature drops (achieving the cooling function), forming cool fresh air.

[0075] The cooled air is introduced into the main body of the range hood 1 from the outer shell 31 through the air duct 32, and then discharged through the exhaust head 33 at the bottom of the base plate 2;

[0076] The spoiler 34 is rotatably installed inside the air outlet 331, and its angle is controlled by the drive mechanism 35. By adjusting the tilt direction of the spoiler 34, the air outlet angle and diffusion range of the fresh air can be changed to achieve directional air supply or wide-angle air supply, improve the air circulation efficiency in the kitchen, and effectively avoid direct airflow from interfering with cooking operations.

[0077] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
