Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to an oil-gas separation detection device and a cooking utensil. Background Technology

[0002] As consumers increasingly demand health and quality of life, and with the development of related technologies in kitchen appliances, kitchen appliances with oil-gas separation functions are becoming more and more popular. When cooking food in kitchen appliances, especially during steaming and grilling, a significant amount of oil fumes (oil-gas mixtures) are generated. If these fumes are not separated, they may be released into the indoor environment. These fumes contain various harmful substances, such as polycyclic aromatic hydrocarbons and benzo[a]pyrene, which can diffuse in indoor air and, when inhaled, increase the risk of respiratory diseases, cardiovascular diseases, and even lung cancer. Furthermore, if directly discharged outdoors, the unseparated fumes will enter the atmosphere, forming inhalable particulate matter and other pollutants, affecting air quality.

[0003] Common oil-gas separation technologies include centrifugal separation, condensation separation, and filtration separation. Centrifugal and condensation separation technologies often require additional equipment to achieve centrifugation or maintain the condensation temperature. Filtration separation technology uses various filter materials, such as metal mesh, fiber mesh, and ceramic filter elements, to filter oil fumes, trapping oil droplets on the filter while allowing the gas to pass through. Regardless of the oil-gas separation technology used, the separated oil needs to be stored. Currently, most electrical appliances require visual inspection to determine whether oil needs to be emptied or cleaned. When oil spills, it may flow into the appliance and cause corrosion, reducing its lifespan. Utility Model Content

[0010] Preferably, a connecting portion is provided at the end of the first oil-gas separation surface, and the connecting portion is arranged at a second angle with the first oil-gas separation surface, the second angle being 100°-150°.

[0011] Preferably, the interval between adjacent connecting portions is greater than the distance between the first included angle in adjacent separating plates and the first oil-gas separation surface on the same side.

[0012] Preferably, the inner wall of the frame is provided with a first limiting protrusion, and the main body of the bracket is provided with a first buckle facing downward. When the oil-gas separation component is installed into the frame, the first buckle is buckled and connected to the first limiting protrusion.

[0013] Preferably, the upper wall of the frame is provided with a downwardly recessed first step, and the end of the first step is provided with a through first limiting hole. When the cover is connected to the frame, the first step corresponds to the position of the hook assembly. The hook assembly is provided with a downward-facing hook, and the hook is snapped into the limiting hole.

[0014] Preferably, the upper wall of the frame is provided with a downwardly recessed first step, and a raised second limiting protrusion is provided on the first step. When the cover is connected to the frame, the first step corresponds to the position of the hook assembly. The hook assembly has a through second limiting hole, and the second limiting hole is connected to the second limiting protrusion.

[0015] Preferably, the oil-gas separation assembly further includes a riveting plate and a spring. The riveting plate has multiple connecting holes. At least one upper rotating shaft and a lower rotating shaft are provided at the end of the separation plate. The upper rotating shaft is movably connected to the connecting holes, and the lower rotating shaft is movably connected to the slot. One end of the spring is fixedly connected to the riveting plate, and the other end is fixedly connected to the bracket body. The spring can drive multiple separation plates to rotate toward the spring side through the riveting plate.

[0016] Preferably, the oil-gas separation assembly further includes a connecting bracket, a switch, and a spring. The connecting bracket is fixedly connected to the riveting piece. A through switch hole is provided on the side of the bracket body. The switch passes through the switch hole and is fixedly connected to the connecting bracket. The spring is a wavy spring comprising upper and lower layers. The spring is fixedly connected between the riveting piece and the bracket body. The switch is limited between the springs.

[0017] This utility model also provides a cooking appliance, which includes a flue pipe, an oil collection box, and an oil-gas separation and detection device as described in any of the above. The oil-gas separation and detection device is disposed in the flue pipe. When the flue gas is discharged through the flue pipe, the oil-gas separation and detection device adsorbs the oil in the flue gas and stores it in the oil collection box.

[0018] Compared with existing technologies, the oil-gas separation detection device and cooking appliance of this solution have at least the following beneficial effects:

[0019] 1. The oil-gas separation detection device in this solution has an oil receiving box with detection function on the side of the oil-gas separation component and the cover. It can detect the amount of oil stored in the oil receiving box and provide reminders, which can prevent excessive oil from overflowing into the device or electrical components, thereby improving its service life.

[0020] 2. The oil-gas separation detection device in this solution is composed of a detachable frame, oil-gas separation components, and a cover. It uses multiple separation plates to adsorb and separate oil stains in the fumes. The multiple separation plates form multiple channels for the fumes to pass through. When the fumes enter the channels, the oil stains first contact the separation surface and adhere to it. The fumes are then discharged from the channels, which avoids the oil stains from clogging the oil-gas separation detection device after long-term use, and achieves efficient separation with a longer service life.

[0021] 3. Furthermore, the separation plates in this solution adopt a W-shaped double-wing structure with the first oil-gas separation surface, the second oil-gas separation surface, and the first oil-gas separation surface connected in sequence. Multiple separation plates are arranged in an array, which can effectively increase the inlet area of ​​oil fumes and facilitate the entry of oil fumes. At the same time, due to the W-shaped double-wing structure, the channel of adjacent separation plates is smaller than the inlet, which effectively improves the oil-gas separation degree.

[0037] The technical solution of the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it. However, the embodiments cited do not limit the present utility model. In this embodiment, it should be understood that the orientation or positional relationship indicated by terms such as "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model.

[0038] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element and integrated with it, or there may be an intermediate element present at the same time. The terms "installation", "one end", "the other end" and similar expressions used in the present utility model are only for the purpose of illustration.

[0039] Please refer to Figures 1-10 , an oil-gas separation detection device is provided in an embodiment of the present utility model, which includes a skeleton 1, an oil-gas separation component 2 and a cover 3. The oil-gas separation component 2 is detachably installed in the skeleton 1, and the cover 3 is detachably connected to the skeleton 1 to fix the oil-gas separation component 2 in the skeleton 1. The oil-gas separation detection device is used to be installed on the smoke exhaust passage of a cooking appliance, and the oil fume is discharged after being separated and adsorbed by the oil-gas separation detection device, so as to achieve the adsorption and separation of oil stains. Specifically, the oil-gas separation detection device includes the following structures:

[0040] Please refer to Figure 2 , one side of the skeleton 1 is open outward and forms an installation groove 101 with a receiving cavity inside, which is used to install the oil-gas separation component 2. It can be understood that the outward opening mentioned here means that one side of the skeleton 1 is in an unobstructed open state, and other components can be installed into the installation groove 101 from this side. The middle part of the skeleton 1 is hollow, that is, the outer shape of the skeleton 1 is in the shape of "mouth" or "凵", corresponding to the position of the separation sheet 202 of the oil-gas separation component 2, and is used for the oil fume to pass through.

[0041] Please refer to Figure 3 、 Figures 8-9The oil-gas separator 2 includes a support body 201 and multiple separation plates 202. Multiple slots 203 are spaced apart on opposite sides of the support body 201. The separation plates 202 are spaced apart and mounted on the slots 203, forming channels for oil and gas to pass between adjacent separation plates 202. It is understood that the dimensions of the support body 201 correspond to and match the dimensions of the mounting groove 101, allowing the support body 201 to be pushed into the mounting groove 101. By employing multiple separation plates 202 forming channels, the risk of oil clogging the oil-gas separator 2 after long-term use can be avoided.

[0042] Please refer to Figure 4 The cover 3 is used to install and fix the oil-gas separation component 2 to the open end of the frame 1. The cover 3 includes a cover side plate 301 and hook assemblies 302 symmetrically arranged at both ends. The hook assemblies 302 extend outward relative to the cover side plate 301. It can be understood that the hook assemblies 302 extending outward here means that the hook assemblies 302 protrude relative to the cover side plate 301. When the cover 3 is installed and connected to the frame 1, the hook assemblies 302 extend into the frame 1 and are fixedly connected to the frame 1. An oil receiving box 304 is provided on the side of the cover 3. The oil receiving box 304 and the cover 3 are provided with oil leakage holes that pass through both. When the oil-gas separation detection device is in use, the oil-gas separation detection device is tilted towards the oil receiving box 304. When the oil adsorbed on the separation plate 202, it will flow along the separation plate 202 to the end and flow into the oil receiving box 304, thus realizing the storage of oil. Furthermore, an oil level sensor 305 is installed at one end of the oil receiving box 304 to detect the oil level or oil volume in the oil receiving box 304. When the oil volume reaches the warning line, an alarm is issued to remind the user to clean it. This can prevent oil from flowing out of the oil receiving box 304 and becoming difficult to clean.

[0043] Furthermore, the oil level sensor is electrically connected to the controller. This oil-gas separation detection device can operate in two modes: first, it uses the controller to automatically time and remind the user to clean the oil; second, it uses the oil level sensor to detect the oil level. When the oil level or oil liquid level exceeds a preset value, the detection information is sent to the controller, issuing a warning to remind the user to clean. This dual detection system promptly reminds the user to clean the oil, and also extends the product's lifespan.

[0044] The oil-gas separation detection device in this embodiment uses a detachable oil-gas separation component 2 and a cover 3 to be installed and connected to the frame 1, making the structure easy to assemble. The separation plate 202 is used as the main component for separating and adsorbing oil stains, which can avoid the accumulation of oil stains and the blockage phenomenon. The oil stain separation efficiency and lifespan are both high.

[0045] Please refer to Figures 8-10 In this embodiment, the separation plate 202 includes a first oil-gas separation surface 204 and a second oil-gas separation surface 205. The first oil-gas separation surface 204, the second oil-gas separation surface 205, and the first oil-gas separation surface 204 are connected in sequence. The first separation surface and the second separation surface are set at a first included angle 206, which is 100°-120°. The second oil-gas separation surface 205 has a central bulge on the side facing the first included angle 206. Understandably, the two sides of the second oil-gas separation surface 205 are respectively connected to the first oil-gas separation surface 204, and the second oil-gas separation surface 205 and the first oil-gas separation surface 204 form a certain included angle, which is 100°-120°. Simultaneously, the central bulge of the second oil-gas separation surface 205 causes the separation plate 202 to form a W-shaped double-wing structure. Since the oil-gas separation detection device is working, the separation plate 202 is vertically arranged, i.e., in a W-shaped double-wing structure. Or form In this configuration, when oil fumes pass through the oil-gas separation component 2, they first come into contact with the first oil-gas separation surface 204, and oil stains are adhered to the separation plate 202. In addition, due to the W-shaped double-wing structure, a centrifugal region is formed in the middle of the separation plate 202. That is, when the volume of oil fume is particularly large, the oil fume will be filtered laterally through the second oil-gas separation surface 205, realizing secondary separation of oil fumes to improve the separation success rate.

[0046] Furthermore, such as Figure 10 As shown, the first included angle 206 formed by the first oil-gas separation surface 204 and the second oil-gas separation surface 205 is rounded. Therefore, the angle of the first included angle 206, which is 100°-120°, refers to the angle formed by the extension lines of the centers of the first oil-gas separation surface 204 and the second oil-gas separation surface 205. For example, the angle of the first included angle 206 can be 100°, 110°, 120°, etc. Rounding the first included angle 206 makes the transition between the first oil-gas separation surface 204 and the second oil-gas separation surface 205 smoother. When grease adheres, this angle range is more conducive to the dripping of oil stains, reducing oil residue and playing a better role in oil repellency. Furthermore, the separation plate 202 is made of metal materials, such as aluminum alloy, stainless steel, or other composite metal materials, with a thickness of 1mm-1.2mm. This achieves a lightweight effect, is simple to produce, and has a stable structure. Combined with the W-shaped double-wing structure, it will not deform and cause performance degradation under high temperature and high wind conditions.

[0047] Please refer to Figure 10In this embodiment, a connecting portion 207 is provided at the end of the first oil-gas separation surface 204. It can be understood that the connecting portion 207 is provided at the end of the first oil-gas separation surface 204 at both ends of the separation plate 202. The connecting portion 207 is equivalent to an outward extension of the first oil-gas separation surface 204, used to connect with the slot 203 to fix the position of the separation plate 202. The connecting portion 207 is set at a second included angle 218 with the first oil-gas separation surface 204. The second included angle 218 is also rounded, which allows oil fumes to enter from the channel between adjacent separation plates 202. When the oil comes into contact with the second included angle 218, the rounded second included angle 218 helps the oil drip off, reducing oil residue. The second included angle 218 is between 100° and 150°, preferably 100°, 110°, 120°, 130°, 140°, 150°, etc. The angle 218 affects the narrowest distance between adjacent separating plates 202, thus affecting the speed at which oil fumes enter the channel and the separation efficiency. If the angle is too large, the distance between adjacent separating plates 202 will be too large, and the oil fumes will pass through directly without adsorption and separation, resulting in a low oil-gas separation rate of the oil-gas separation detection device. If the angle is too small, the distance between adjacent separating plates 202 will be too small, which will affect the airflow rate per minute of the oil-gas separation detection device and the efficiency of oil-gas separation.

[0048] Please refer to Figures 8-10In a further embodiment, the spacing between adjacent connecting portions 207 is greater than the distance between the first included angle 206 of the adjacent separating plates 202 and the first oil-gas separation surface 204 on the same side. It can be understood that since the separating plates 202 adopt a W-shaped double-wing structure and are provided with connecting portions 207 for connection and fixation, the spacing between adjacent separating plates 202 is not completely consistent. At the oil fume inlet, that is, the spacing between adjacent connecting portions 207 will be larger, so as to ensure that oil fumes can enter. Secondly, in the case of two adjacent separating plates 202 on the same side, the distance from the first included angle 206 of one separating plate 202 to the first oil-gas separation surface 204 of the adjacent separating plate 202 is less than the spacing between adjacent connecting portions 207. For example, the distance between the first included angle 206 and the first oil-gas separation surface 204 on the same side can refer to the shortest distance from the first included angle 206 to the first oil-gas separation surface 204 on the same side, which is less than the interval distance between adjacent connecting portions 207. Alternatively, it can refer to the farthest distance from the first included angle 206 to the first oil-gas separation surface 204 on the same side, which is less than the interval distance between adjacent connecting portions 207. This structural arrangement can narrow a portion of the channel, thereby increasing the contact area between the first oil-gas separation surface 204 and the oil fumes to improve the oil-gas separation rate. In addition, the second oil-gas separation surface 205 has a convex structure in the middle, which increases the interval distance between adjacent separation plates 202 in the area of ​​the second oil-gas separation surface 205, forming a centrifugal region. When the amount of oil fumes is large, the oil fumes that cannot be discharged in time will accumulate in the area of ​​the second oil-gas separation surface 205 and undergo secondary lateral separation through the second oil-gas separation surface 205, improving the oil-gas separation rate under conditions of large amounts of oil fumes.

[0049] Please refer to Figure 2 , Figures 5-7In this embodiment, a first limiting protrusion 102 is provided on the inner wall of the frame 1, and a downward-facing first buckle 208 is provided on the support body 201. When the oil-gas separation component 2 is installed into the frame 1, the first buckle 208 is snapped into the first limiting protrusion 102. For example, a first limiting protrusion 102 is provided on the lower inner wall of the frame 1, and a downward-facing first buckle 208 is provided on the lower bottom surface of the support body 201. The first buckle 208 and the support body 201 can be integrally formed and have a certain elasticity. Specifically, it can be a downward-facing barb-shaped structure, and its position corresponds to the position of the first limiting protrusion 102. When the oil-gas separation component 2 is pushed into the frame 1, the first buckle 208 first moves upward under the action of the first limiting protrusion 102. After passing the first limiting protrusion 102, the first buckle 208 is snapped into the first limiting protrusion 102. If the oil-gas separator assembly 2 needs to be replaced, simply pull it outwards. The first clip 208 will also move upwards and disengage under the action of the first limiting protrusion 102. This achieves both a relatively fixed and detachable connection of the oil-gas separator assembly 2.

[0050] Please refer to Figure 2 , Figures 5-7 In a preferred embodiment, the upper wall of the frame 1 is provided with a downwardly recessed first step 103, and the end of the first step 103 is provided with a through first limiting hole 104. When the cover 3 is connected to the frame 1, the first step 103 corresponds to the position of the hook assembly 302. The hook assembly 302 is provided with a downward-facing hook, which is engaged with the first limiting hole 104. Understandably, the depth of the downward recess of the first step 103 corresponds to the thickness of the hook assembly 302. When the hook assembly 302 is fixedly connected to the first step 103, the hook portion of the hook assembly 302 hooks into the first limiting hole 104, making the cover 3 and the frame 1 relatively fixedly connected. At this time, the hook assembly 302 is flush with the upper surface of the frame 1. The cover 3 and the frame 1 are installed and fixed through the cooperation of the limiting hole and the hook assembly 302, achieving a screwless design, easy installation and assembly, and high production efficiency.

[0051] Please refer to Figure 2 , Figures 5-7In a preferred embodiment, the upper wall of the frame 1 is provided with a downwardly recessed first step 103, and a raised second limiting protrusion 105 is provided on the first step 103. When the cover 3 is connected to the frame 1, the first step 103 corresponds to the position of the hook assembly 302. The hook assembly 302 has a through second limiting hole 303, which engages with the second limiting protrusion 105. Understandably, the depth of the downward recess of the first step 103 corresponds to the thickness of the hook assembly 302. When the hook assembly 302 is fixedly connected to the first step 103, the second limiting protrusion 105 engages with the second limiting hole 303, making the cover 3 and the frame 1 relatively fixedly connected. At this time, the hook assembly 302 is flush with the upper surface of the frame 1. The cover 3 and the frame 1 are fixedly installed through the engagement of the limiting hole and the limiting protrusion, achieving a screwless design, easy installation and assembly, and high production efficiency.

[0052] For example, a first limiting hole 104 and a second limiting protrusion 105 can be provided on the first step 103 of the frame 1 at the same time, and a hook and a second limiting hole 303 are correspondingly provided on the hook assembly 302 at the same time. In this way, the connection between the cover 3 and the frame 1 can be fixed in both directions, and it is not easy to fall off during use.

[0053] Please refer to Figures 12-14 In other preferred embodiments, the oil-gas separation assembly 2 further includes a riveting piece 209 and a spring 210. The riveting piece 209 has multiple connecting holes 211. The ends of the separation pieces 202 are provided with at least an upper rotating shaft 212 and a lower rotating shaft 213. The upper rotating shaft 212 is movably connected to the connecting holes 211, and the lower rotating shaft 213 is movably connected to the slot 203. One end of the spring 210 is fixedly connected to the riveting piece 209 and the other end is fixedly connected to the bracket body 201. The spring 210 can drive multiple separation pieces 202 to rotate toward the side of the spring 210 through the riveting piece 209. Understandably, the rivet 209 connects multiple or all of the separation pieces 202 together through the connecting hole 211. It is connected to the rivet 209 through the upper rotating shaft 212 and to the slot 203 through the lower rotating shaft 213. This allows the separation piece 202 to rotate with the lower rotating shaft 213 as the pivot point. The end of the rivet 209 is fixedly connected to the bracket body 201 through the spring 210. Under the tension of the spring 210, the separation piece 202 rotates toward the spring 210, which further fixes the position of the separation piece 202 and maintains the stability of the separation piece 202 even under heavy air conditions.

[0054] Please refer to Figures 12-14For example, the two ends of the separating piece 202 can be provided with an upper rotating shaft 212, a middle rotating shaft and a lower rotating shaft 213. The upper rotating shaft 212 and the middle rotating shaft are both connected to the riveting piece 209, and the lower rotating shaft 213 is movably connected to the slot 203. By providing multiple middle rotating shafts, the positions of the separating piece 202 and the riveting piece 209 can be further fixed.

[0055] Please refer to Figures 11-14 In this preferred embodiment, the oil-gas separation assembly 2 further includes a connecting bracket 214, a switch 215, and a spring piece 216. The connecting bracket 214 is fixedly connected to the riveting piece 209. A through switch hole 217 is provided on the side of the bracket body 201. The switch 215 passes through the switch hole 217 and is fixedly connected to the connecting bracket 214. The spring piece 216 is a wave-shaped spring piece 216 including upper and lower layers. The spring piece 216 is fixedly connected between the riveting piece 209 and the bracket body 201. The switch 215 is limited between the spring pieces 216. Understandably, the connecting bracket 214 is fixedly connected to the riveting piece 209 on the side facing the cover 3, and the switch 215 is fixedly connected to the connecting bracket 214 after passing through the switch hole 217. When the switch 215 is pushed to move within the stroke of the switch hole 217, it can drive the riveting piece 209 to move in the same direction. The riveting piece 209 is connected to the separating piece 202, so the separating piece 202 can be driven to rotate. The range of the rotation angle depends on the stroke distance of the switch hole 217. In this embodiment, the rotation angle of the separating piece 202 is 0°-90°. When the rotation angle is 0°, that is, there is no rotation, the separating piece 202 can withstand the maximum flow of oil fume. When the rotation angle is 90°, the separating pieces 202 are in contact with each other, and the oil-gas separation assembly 2 is in the closed state. The spring 216 is used to limit the position of the switch 215 within the switch hole 217. The spring 216 has two layers, and the switch 215 is positioned between the two layers of spring 216. The wavy shape of the spring 216 allows the switch 215 to be fixed at different positions within the spring 216, which in turn allows it to be fixed at different positions within the switch hole 217. This enables the separating plate 202 to rotate at different angles and remain relatively fixed under the action of the switch 215, the spring 216, and the rivet 209, thereby controlling the separation of the separating plate 202 from the grease and the width of the channel between the separating plates 202. It is understood that the spring 216 is positioned away from the spring 210. Figure 11-13 As shown, the spring 210 is located on the right side of the oil-gas separation assembly 2, while the spring plate 216 is fixed on the left side of the switch hole 217. In this way, the spring 210 will maintain a continuous pulling force to the right, which can make it more stable when the switch 215 is in the rightmost position. At this time, the separation plate 202 is in a completely closed state, which can prevent dust from entering the inside of the oil-gas separation detection device or the inside of the electrical appliance when it is not in use, and can also prevent small animals such as cockroaches from entering, thus protecting the circuit of the electrical appliance.

[0056] In other embodiments, the switch 215 can be configured as an internal switch built between the oil-gas separation component 2 and the frame 1. A drive device is provided on one side of the switch 215, and the output end of the drive device is abutted or fixedly connected to the switch 215. A control panel is provided on the oil-gas separation detection device or electrical appliance. By controlling the drive device, the movement stroke of the internal switch is driven to control the rotation angle of the separation plate 202. This enables intelligent control, and the stroke of the internal switch becomes stepless control. That is, the rotation angle of the separation plate 202 can be any angle from 0° to 90°. This allows the oil-gas separation detection device to automatically control the angle of the separation plate 202 according to the gas flow rate of the oil fume, thus maintaining the optimal oil-gas separation rate.

[0057] This utility model also provides a cooking appliance, which includes a flue pipe, an oil collection box, and an oil-gas separation and detection device as described above. The oil-gas separation and detection device is installed inside the flue pipe. When the flue gas is discharged through the flue pipe, the oil-gas separation and detection device adsorbs the oil in the flue gas and stores it in the oil collection box.
