Description

Technical Field

[0001] This utility model belongs to the field of cooking appliance technology, specifically relating to a host computer component and integrated stove suitable for situations with a large amount of oil fumes. Background Technology

[0002] Integrated cooktops, as a modern kitchen appliance, have become widely used in family kitchens in recent years due to their compact structure, space-saving design, and high efficiency in fume extraction. One of the core functions of integrated cooktops is to capture and remove cooking fumes and exhaust gases effectively during cooking through a built-in fume extraction system, thereby maintaining fresh kitchen air and protecting user health and environmental hygiene.

[0003] However, integrated cooktops still have the problem of oil fume escape during actual use. Currently, the baffles of mainstream integrated cooktops are usually located at the back of the cooktop, extending vertically upwards from the countertop. When cooking is started, especially when stir-frying or other operations that generate a large amount of oil fume instantly, the oil fume rises and spreads upwards at the edge of the cookware. It is difficult for the baffle to effectively block and guide the airflow of the oil fume rising from the cookware in the first instance.

[0004] The harm caused by escaping cooking fumes is multifaceted. Escaping fumes directly contaminate countertops, walls, and cabinet surfaces around the stove, forming stubborn grease stains that are difficult to remove and accelerating the aging of cookware. Cooking fumes contain unburned grease particles, carcinogens such as benzo[a]pyrene, aldehydes, and other harmful volatile substances, posing a threat and adverse effect on the respiratory health of kitchen users. Simultaneously, users will clearly perceive the lingering smell of cooking fumes, and experience discomfort such as pungent eyes and a burning sensation in the nose, affecting the comfort and enjoyment of cooking. Utility Model Content

[0005] This utility model provides a host computer component with an adjustable smoke collection structure and an integrated stove.

[0006] The technical solution of this utility model is based on solving the many problems caused by the escape of oil fumes during the cooking stage when there is a large amount of oil fumes or an explosion of oil fumes.

The auxiliary smoke inlet is connected to an auxiliary smoke guiding channel disposed inside the smoke collection plate assembly, and the auxiliary smoke guiding channel is connected to the main smoke guiding channel.

[0020] In a further embodiment, a status sensor is also included, which is disposed on the lower surface of the smoke collection plate assembly, for collecting the status parameter information of the oil fumes and sending the status parameter signal of the oil fumes to the information processing module;

[0021] The information processing module receives the status parameter signal of the oil fume and sends the control signal to the power module.

[0022] The power module receives control signals and performs operations such as extending or retracting the electric push rod, and moving up or down driven by the micro motor.

[0023] In a preferred embodiment, the status sensor is a temperature sensor and / or an oil fume concentration sensor.

[0024] In a preferred embodiment, the smoke collection plate assembly, when extended to its maximum extent, forms a smoke collection area that covers the area above the burner.

[0041] The present invention will be further explained in conjunction with the embodiments:

[0042] The core technical problem faced by the technical solution of this application embodiment stems from the inventor's accurate understanding of the prior art. Therefore, how to optimize the oil fume extraction effect under heavy oil fume conditions is a technical problem that the inventor urgently needs to solve.

[0043] It should be noted that the embodiments do not constitute a limitation on the scope of protection of the claims of this utility model. All technical solutions that can be reasonably expected by those skilled in the art based on the technical concepts provided / proved by the embodiments should be covered within the scope of protection of the claims of this utility model.

[0044] The specific implementation examples are detailed below:

[0045] First, please refer to the appendix. Figures 1-4 This embodiment first provides a host computer with an adjustable smoke collection structure, which includes a smoke guide plate assembly 1, a smoke collection plate assembly 2 and a flow guide assembly 5;

[0046] The smoke guide plate assembly 1 is located at the edge of the host computer and is vertically arranged on one side of the burner 3. The smoke guide plate assembly 1 has a continuous hollow main smoke channel 1.1 inside. The main smoke channel 1.1 has a main smoke inlet 1.1 on the side facing the burner 3. The main smoke inlet 1.1 is a horizontally opened strip-shaped through hole and is located in the upper area of ​​the main smoke channel 1.1. In the working state of smoke extraction, the smoke is drawn into the main smoke channel 1.1 through the main smoke inlet 1.1 and discharged.

[0047] The smoke collection plate assembly 2 is located on top or above the smoke guide plate assembly 1. Simultaneously, the smoke collection plate assembly 2 is also located above the area where the burner 3 is located. The smoke collection plate assembly 2 has a telescopic structure. Specifically, the smoke collection plate assembly 2 includes a base smoke collection plate 2.3 and a telescopic smoke collection plate 2.4 that telescopically moves relative to the base smoke collection plate 2.3. The base smoke collection plate 2.3 is located on top or above the smoke guide plate assembly 1. An electric push rod 2.5 is provided on the base smoke collection plate 2.3. The two sides of the telescopic smoke collection plate 2.4 are connected to the base smoke collection plate 2.3 via a slide rail structure 2.6 to achieve telescopic movement. In this embodiment, the reciprocating direction of the electric push rod 2.5, the sliding direction of the slide rail structure 2.6, and the telescopic direction of the telescopic smoke collection plate 2.4 are parallel to each other to achieve smooth telescopic movement of the telescopic smoke collection plate 2.4.

[0048] Please refer to the attached document. Figure 5 The three edges of the basic smoke-collecting plate 2.3 near the smoke guide plate assembly 1 are folded to increase the overall strength. The folded edges 2.31 also facilitate the formation of a sealed cavity. On the inner side of the folded edge closest to the smoke guide plate assembly 1, there is at least one oil leakage hole 2.32. When the smoke passes by, the condensed grease is collected in the sealed cavity of the smoke baffle plate and flows down the rear wall of the smoke collection hood through the oil leakage hole 2.32.

[0049] The lower surface of the telescopic smoke-collecting plate 2.4 is provided with a smoke-collecting base plate, and the smoke-collecting base plate is provided with a smoke-collecting groove 2.41 that is recessed towards the direction of smoke escape. Each burner 3 has a corresponding smoke-collecting groove 2.41 above it. Each side of the smoke-collecting base plate is provided with a slide rail mounting groove 2.42. The extension direction of the slide rail mounting groove is parallel to the telescopic direction of the telescopic smoke-collecting plate 2.4. The smoke-collecting groove 2.41 can increase the amount of smoke collected and, to a certain extent, contain the smoke and limit its further diffusion.

[0050] An alarm unit 2.44 is also installed on the smoke collection base plate, which can provide an alarm function in abnormal situations.

[0051] The flow guiding component 5 is located above the smoke guide plate component 1 and at the far end of the smoke gathering plate component 2 (i.e., the end away from the smoke guide plate component 1). The core component of the flow guiding component 5 is the flow guiding plate 5.1, which is designed to move downward or approximately downward to form a vertical guiding surface. The flow guiding plate 5.1 can expand the range of oil fume coverage.

[0052] Therefore, when the smoke guide plate assembly cannot meet the requirements for absorbing oil fumes, it is usually under cooking conditions where the amount of oil fumes is large or increases rapidly, such as stir-frying. The escaping oil fumes flow upward. The smoke collection plate assembly and the flow guide assembly 5 in this embodiment can prevent the oil fumes from escaping upward. Furthermore, the coverage of the smoke collection plate assembly 2 and the flow guide plate 5.1 can be adjusted by extending and retracting to adapt to different amounts of oil fume escaping.

[0053] In a preferred embodiment, the smoke-collecting plate assembly 2, when extended to its maximum extent, can cover the area above the burner 3.

[0054] In further embodiments, please continue to refer to the appendix. Figure 3The guide plate 5.1 is mounted vertically on the distal end of the smoke collection plate assembly 2 via a vertical guide mechanism. Specifically, the guide plate 5.1 achieves vertical displacement via a guide rail 5.2, and its lifting height is precisely controlled by a micro motor 5.3 as the drive source. The guide rail 5.2 is connected to the smoke collection plate assembly 2 via silicone. The micro motor 5.3 is installed inside the telescopic smoke collection plate 2.4, and the motor shaft of the micro motor 5.3 is connected to the guide rail 5.2 via screws, snap rings, etc., to achieve the vertical movement of the guide plate 5.1.

[0055] This mechanical layout allows the baffle 5.1 to retract above the smoke collection plate assembly 2 when not in operation, thus avoiding interference with the normal use of the stove.

[0056] In this embodiment, the vertical lifting design significantly optimizes the structural compactness, allowing the deflector 5.1 to move to the optimal working height when needed and return to an upper position that does not obstruct operation when stored. The precise positioning capability driven by the micro motor 5.3 ensures that the deflector 5.1 is always in the most effective blocking position, avoiding performance fluctuations caused by manual adjustment.

[0057] Furthermore, at least two parallel vertical guide rails 5.2 are provided within the frame of the flow guiding and protection component 5, and the guide plate 5.1 is connected to the guide rails by sliders on both sides; the micro motor 5.3 converts the rotational motion into the linear displacement of the guide plate 5.1 through a gear rack or lead screw mechanism.

[0058] In further embodiments, please continue to refer to the appendix. Figures 1-4 The smoke collection plate assembly 2 is also equipped with a status sensor 4, which is specifically located on the lower surface of the smoke collection plate assembly 2. The status sensor 4 is used to collect the status parameter information of the oil fumes and send the status parameter signal of the oil fumes to the information processing module. The information processing module receives the status parameter signal of the oil fumes and sends the control signal to the power module. The power module (such as a motor) receives the control signal and performs the extension or retraction operation of the electric push rod 2.5 and the up and down movement driven by the micro motor 5.3.

[0059] In further embodiments, please continue to refer to the appendix. Figures 1-4 The smoke collection plate assembly 2 has a continuous hollow auxiliary smoke guiding channel 2.2 inside. The auxiliary smoke guiding channel 2.2 is also provided with an auxiliary smoke inlet 2.1 on the side of the auxiliary smoke guiding channel 2.2 facing the burner 3, that is, the downward side. The auxiliary smoke inlet 2.1 is connected to the auxiliary smoke guiding channel 2.2, and the auxiliary smoke guiding channel 2.2 is connected to the main smoke guiding channel 1.2.

[0060] When the fume extraction system is in operation with a large volume of oil fumes, the telescopic smoke collection plate 2.4 extends and the auxiliary smoke inlet 2.1 is exposed. The escaped oil fumes can be sucked into the auxiliary smoke guide channel 2.2 through the auxiliary smoke inlet 2.1 and then discharged into the main smoke guide channel 1.2 before being discharged.

[0061] Based on the aforementioned technical solution, the auxiliary smoke inlet 2.1 located below the telescopic smoke gathering plate 2.4 captures and absorbs the escaped oil fumes, thus integrating the functions of locking and absorbing the escaped oil fumes. This ensures excellent oil fume absorption even under cooking conditions with large amounts of oil fumes or a rapid increase in oil fumes.

[0062] In some embodiments, the status sensor 4 is a temperature sensor. When the temperature detected by the temperature sensor is greater than the preset temperature, it usually means that a large amount of high-temperature oil fumes are overflowing. At this time, the electric push rod 2.5 can be controlled to extend, so that the telescopic smoke gathering plate 2.4 extends and the auxiliary smoke inlet 2.1 is exposed to participate in the removal of oil fumes. The micro motor 5.3 drives the guide plate 5.1 to descend. When the detected temperature is less than the preset temperature, the electric push rod 2.5 is controlled to retract, so that the telescopic smoke gathering plate 2.4 retracts synchronously, and the micro motor 5.3 drives the guide plate 5.1 to rise.

[0063] In other embodiments, the state sensor 4 can also be an oil fume concentration sensor. When the oil fume concentration detected by the oil fume concentration sensor is greater than the preset temperature, it means that a large amount of oil fume has overflowed. Similarly, the electric push rod 2.5 can be controlled to extend, so that the telescopic smoke gathering plate 2.4 extends and the auxiliary smoke inlet 2.1 is exposed to participate in the removal of oil fumes. The micro motor 5.3 drives the guide plate 5.1 to descend. When the detected oil fume concentration is less than the preset oil fume concentration, the electric push rod 2.5 is controlled to retract, so that the telescopic smoke gathering plate 2.4 retracts synchronously, and the micro motor 5.3 drives the guide plate 5.1 to rise.

[0064] In other embodiments, a temperature or oil fume concentration sensor may be installed at the corresponding position of each of the two burners to ensure that the two burners are within their sensing range;

[0065] When cooking, users often need to operate kitchen utensils such as pots and pans, and often cannot or do not have time to operate the retractable smoke collection plate 2.4 to extend it, resulting in the escape of oil fumes. Therefore, the technical solution of this embodiment uses the detected temperature or oil fume concentration as the standard for judging whether the smoke collection plate assembly has extended, and automatically controls the extension of the smoke collection plate assembly to lock and absorb the escaped oil fumes in time, thereby improving the oil fume absorption effect.

[0066] In a further embodiment, the host computer is also equipped with a timing module, which is used to collect the duration when the state parameter of the oil fume is greater than a preset value, and send the duration parameter signal to the information processing module; the information processing module receives the state parameter signal and the duration parameter signal of the oil fume, and sends the control signal to the power module.

[0067] When the parameter detected by the status sensor 4 is greater than the set value, and the duration of the state is greater than the set time threshold, the electric push rod 2.5 is pushed out to extend the telescopic smoke gathering plate 2.4.

[0068] In the technical solution of this embodiment, a comparison between the duration value and the preset time threshold is introduced to determine whether the smoke gathering plate assembly extends after the state sensor 4 detects that the parameter state is maintained for a period of time, so as to improve the accuracy of the judgment and prevent the smoke gathering plate assembly from frequently extending and retracting.

[0069] In the preferred embodiment, please continue to refer to the appendix. Figures 1-4 The extent of extension of the telescopic smoke gathering plate 2.4 is positively correlated with the magnitude of the detected parameters. That is, the greater the detected parameters exceed the preset parameter values, the greater the extension amplitude of the telescopic smoke gathering plate 2.4.

[0070] In the technical solution of this embodiment, the larger the parameter detected by the state sensor 4, the more the telescopic smoke gathering plate 2.4 is extended to match the amount of oil smoke, thereby achieving dynamic extension and obtaining a suitable smoke gathering range. For example, the higher the detected oil smoke concentration, the more the amount of oil smoke increases, and the more the telescopic smoke gathering plate 2.4 is extended to obtain a larger smoke gathering area.

[0071] The embodiments also relate to integrated cooktops, which include the host computer described in any of the above embodiments.
