Description

Technical Field

[0001] This utility model relates to the field of cooking robot technology, specifically a fume removal device for cooking robots. Background Technology

[0002] With the rapid development of smart home technology, cooking robots, as a new type of kitchen appliance, are gradually entering thousands of households due to their advantages such as automated cooking and convenient operation, effectively solving problems such as time-consuming, laborious, and difficult-to-control heat in traditional cooking processes. However, existing cooking robots still have certain functional defects in actual use: Most cooking robots are not equipped with dedicated fume extraction devices, but only have simple ventilation structures, which cannot achieve efficient purification and targeted exhaust of fumes during the cooking process.

[0003] When a cooking robot is working, the high-temperature stir-frying of ingredients generates a large amount of oil fumes, which contain pollutants such as grease particles and volatile organic compounds. Due to the lack of a targeted fume removal device, these fumes easily diffuse and adhere inside the robot, contaminating its cooking chamber, transmission components, and electrical system, affecting the equipment's lifespan and operational stability. They may also overflow into the kitchen environment, leading to a decline in kitchen air quality and potentially posing a threat to the respiratory health of users. Simultaneously, the diffused fumes will leave grease stains on kitchen walls and countertops, increasing the difficulty of cleaning.

[0004] In addition, the few existing cooking robots with simple smoke extraction structures have poor oil fume filtration effects, which cannot effectively remove odors and fine pollutants from the oil fumes. Their smoke extraction efficiency is low, making it difficult to meet users' needs for a clean and healthy cooking environment in the kitchen. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a fume removal device for cooking robots.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A fume extraction device for a cooking robot includes: a fume extraction chamber, a top cover of which is fixed to the top of the fume extraction chamber by bolts, a fume extraction fan located in the center of the top cover, and multiple filter assemblies inside the fume extraction chamber, each filter assembly including a filter screen and filter elements. The filter screen is laid at the bottom of the fume extraction chamber, and the multiple filter elements are supported on top of the filter screen. The filter screen and filter elements are used to filter the fumes, and the fume extraction fan is used to exhaust the fumes from the cooking robot.

[0007] Preferably, the filter screen is configured with two layers, the lower layer being a coarse filter screen and the upper layer being an air filter screen, and the filter element is configured as an activated carbon filter element.

[0008] Preferably, the top cover of the fume extraction box is equipped with an oil collection trough, which is located below the fume extraction fan.

[0009] Preferably, a smoke sensor is installed at the bottom of the fume extraction box. The smoke sensor is used to detect the concentration of oil fumes and feed it back to the robot host, which then adjusts the speed of the fume extraction fan.

[0010] Preferably, handles are provided on the left and right sides of the top cover of the fume extraction box. The handles are used by the staff to remove the fume extraction box when the filter screen assembly needs to be replaced.

[0011] Compared with the prior art, this utility model provides a fume removal device for cooking robots, which has the following beneficial effects: The filter employs a two-layer structure. The lower, coarse filter initially intercepts large particles of grease and food residue in the fumes, preventing large contaminants from clogging subsequent purification components and extending the overall lifespan of the device. The upper air filter further filters finer grease particles from the fumes, achieving secondary filtration and significantly improving the initial purification effect, laying the foundation for subsequent deep purification. This layered filtration design is highly targeted and efficient, effectively reducing the adhesion of contaminants inside the device and the robot's cavity, thus simplifying cleaning.

[0012] The fume extraction fan is positioned in the center of the fume extraction chamber cover, generating directional negative pressure to quickly draw cooking fumes from the robot's cooking chamber into the fume removal device. This achieves targeted collection and exhaust of the fumes, preventing them from spreading or overflowing inside the robot. Simultaneously, in conjunction with a smoke sensor at the bottom of the fume extraction chamber, the robot's main unit intelligently adjusts the fan speed based on the detected fume concentration. When the fume concentration is high, the fan speed automatically increases to enhance exhaust power; when the concentration is low, the fan speed decreases, balancing exhaust efficiency with energy saving requirements, thus achieving an optimized balance between exhaust efficiency and energy consumption.

[0015] 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.

[0016] Reference Figures 1-4 As shown, this embodiment of a cooking robot fume extraction device includes a fume extraction box 1, which serves as the main mounting carrier of the device. Its top is fixedly connected to the fume extraction box cover 3 by bolts. This detachable connection method ensures structural stability and facilitates subsequent maintenance and replacement of internal components. A fume extraction fan 4 is fixedly installed in the center of the fume extraction box cover 3. This installation position can form a uniform negative pressure field, ensuring the directionality of fume collection. Multiple sets of filter assemblies 2 are detachably installed inside the fume extraction box 1. Each filter assembly 2 consists of a filter screen 201 and filter elements 202. The filter screen 201 is horizontally laid at the bottom of the fume extraction box 1, and the multiple sets of filter elements 202 are vertically supported on top of the filter screen 201, forming a layered purification structure. The filter screen 201 and filter elements 202 work together to complete the graded treatment of fume. A smoke sensor is embedded in the bottom of the fume extraction box 1, and its signal output terminal is electrically connected to the robot host to realize real-time feedback of the fume concentration. Handles 301 are symmetrically fixed on the left and right sides of the top cover 3 of the fume extraction box, providing force points for the overall removal of the fume extraction box 1 and facilitating the replacement and maintenance of the filter assembly 2.

[0017] In some examples, a flexible snap-fit ​​is provided between the filter assembly 2 and the inner wall of the fume extraction box 1. The flexible snap-fit ​​is made of food-grade silicone material, which not only enables the filter assembly 2 to be quickly positioned and installed, but also prevents fumes from leaking from the gaps, improves the sealing performance, and simplifies the disassembly process and reduces the difficulty of maintenance.

[0018] In some examples, filter element 202 uses a honeycomb structure activated carbon filter element. Compared with traditional columnar filter elements, its internal pore distribution is more uniform and its specific surface area is increased, which can significantly improve the adsorption efficiency of volatile organic compounds and odor molecules in cooking fumes, and extend the adsorption saturation cycle, reducing the frequency of replacement.

[0019] In some examples, the inner wall of the oil collection tank 9 is inclined at a certain angle, and an oil guide pipe interface is reserved at the lowest point of the tank. The inclined design allows the filtered and separated grease to automatically converge into the oil guide pipe, which is convenient for directional discharge or collection, avoiding the accumulation and deterioration of grease in the tank and improving the ease of cleaning the device.

[0020] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
