Description

Technical Field

[0001] The present application relates to the technical field of kitchen utensils and equipment, and particularly relates to an efficient smoke filtering device and an integrated stove with oil fume purification. Background Art

[0002] During daily cooking, a large amount of oil fume is often generated. If the oil fume is directly discharged into the air without treatment, it will have an impact on environmental hygiene and human health. In related technologies, most of them set multiple filter meshes in the range hood, and use the filter meshes to filter and purify the oil fume. However, during use, since the small holes of the filter mesh will be attached with grease, a large air resistance is generated to the smoke in the oil fume, resulting in low smoke filtering efficiency and poor filtering effect.

[0056] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0057] In the present application, the orientation or positional relationship indicated by terms such as "upper", "lower", "bottom", "inner", "outer", "horizontal", etc. is the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. These terms are mainly used to better describe the present application and its embodiments, and are not used to limit that the indicated device, element or component must have a specific orientation, or be constructed and operated in a specific orientation.

[0058] Moreover, in addition to being used to indicate orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to specific circumstances.

[0059] In addition, the terms "arranged", "provided with", "connected", and "linked" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there can be internal communication between two devices, components, or parts. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0060] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, components, or parts (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, components, or parts. Unless otherwise specified, the meaning of "a plurality" is two or more.

[0061] During the daily home cooking process, especially when cooking high-fat and high-temperature foods, the generation of cooking fumes is almost inevitable. These cooking fumes are composed of tiny oil droplets and smoke. If not processed in a timely and effective manner, they will be directly discharged into the indoor air and even enter the outdoor environment through windows or exhaust vents, which will not only cause a serious decline in the air quality of the kitchen and the surrounding environment, but may also have a negative impact on human health, such as causing respiratory diseases, eye discomfort, etc.

[0062] Currently, the main method is to use the suction force of the fan in the range hood to discharge the cooking fumes generated during cooking outdoors. At the same time, multiple layers of filter screens are arranged in the range hood, and their fine pores are used to filter the oil particles and smoke in the cooking fumes, making the discharged air relatively clean. However, as the usage time increases, the oil in the cooking fumes will adhere to the surface and pores of the filter screen, resulting in a relatively large resistance of the filter screen to the smoke, making the filtering efficiency of the cooking fumes slow and the filtering effect poor.

[0063] In view of this, the embodiments of the present application provide an efficient smoke filtering device and an integrated stove with cooking fume purification, which can reduce the resistance of smoke filtering and increase the number of collisions between the smoke and the filtering part, thereby improving the filtering efficiency and filtering effect of the smoke.

[0064] Next, the technical solutions of the present application will be further described in conjunction with the embodiments and the drawings.

[0065] Please refer to Figure 1 andFigure 2 , Figure 1 is a perspective view of the high - efficiency smoke filtering device disclosed in the embodiments of the present application, Figure 2 is a schematic diagram of the internal structure of the high - efficiency smoke filtering device disclosed in the embodiments of the present application. A high - efficiency smoke filtering device 10 provided in an embodiment of the present application, the high - efficiency smoke filtering device 10 includes a cabinet 1, a first filtering component 2 and a second filtering component 3. An accommodation cavity 11 is formed inside the cabinet 1, and the cabinet 1 includes a first side 12 and a second side 13 that are opposite to each other. Among them, a first smoke exhaust port 121 is provided on the first side 12, a first smoke suction port 131 is provided on the second side 13, and both the first smoke exhaust port 121 and the first smoke suction port 131 communicate with the accommodation cavity 11. At the same time, the direction pointing from the first smoke suction port 131 to the first smoke exhaust port 121 is defined as the first direction F1. Both the first filtering component 2 and the second filtering component 3 are arranged in the accommodation cavity 11, the second filtering component 3 is arranged at an angle with the first filtering component 2, and the first smoke suction port 131 is located in the first included - angle space 4 formed by the second filtering component 3 and the first filtering component 2.

[0066] Furthermore, the first filtering component 2 includes two first filtering parts 21, and the two first filtering parts 21 are arranged at intervals along the second direction F2 to form a first smoke guiding channel 211; the second filtering component 3 includes two second filtering parts 31, and the two second filtering parts 31 are arranged at intervals along the third direction F3 to form a second smoke guiding channel 311. Among them, the second smoke guiding channel 311 communicates with the first smoke guiding channel 211, and the first smoke guiding channel 211 and the second smoke guiding channel 311 are configured to guide the smoke to be discharged from the first smoke suction port 131 through the first smoke guiding channel 211 and the second smoke guiding channel 311 to the first smoke exhaust port 121. And the second direction F2 and the third direction F3 are both directions that form an angle with the first direction F1, that is, both the first smoke guiding channel 211 and the second smoke guiding channel 311 are inclined at an angle with the first direction F1. In this way, after the smoke enters from the first smoke suction port 131, it enters the first included - angle space 4 formed by the second filtering component 3 and the first filtering component 2, so that the smoke can first contact and be filtered by the first filtering component 2 and the second filtering component 3 after entering the high - efficiency smoke filtering device 10, or, affected by the resistance of the first filtering component 2 and the second filtering component 3, enter the first smoke guiding channel 211 and the second smoke guiding channel 311. Both of these situations can achieve effective filtering of the smoke by the first filtering component 2 and the second filtering component 3. Specifically, after the smoke enters the first included - angle space 4 from the first smoke suction port 131, the smoke is affected by the fan 401 (see Figure 5) The vertical attraction, as well as the inclined design of the first smoke guide channel 211 and the second smoke guide channel 311 at an angle to the first direction F1, increases the number of collisions between the smoke and the two first filtering parts 21 and the two second filtering parts 31. The smoke makes sufficient contact with the two first filtering parts 21 and the two second filtering parts 31, prolonging the passing time of the smoke in the high-efficiency smoke filtering device 10. Thus, the two first filtering parts 21 and the two second filtering parts 31 adsorb and filter the smoke, which is beneficial to improving the filtering effect of the smoke.

[0067] It can be understood that when the two first filtering parts 21 are arranged at intervals along the second direction F2, the two first filtering parts 21 can be arranged in parallel along the second direction F1. Similarly, when the two second filtering parts 21 are arranged at intervals along the third direction F3, the two second filtering parts 31 can be arranged in parallel along the third direction F3. Thus, the two first filtering parts 21 and the two second filtering parts 31 are arranged at an angle to each other.

[0068] In some embodiments, both the first filtering assembly 2 and the second filtering assembly 3 are multiple groups, and the multiple groups of the first filtering assembly 2 are arranged at intervals centered on the center of the accommodation cavity 11, and the multiple groups of the second filtering assembly 3 are arranged at intervals centered on the center of the accommodation cavity 11. In addition, the first smoke guide channels 211 formed by each group of the first filtering assembly 2 are all interconnected, and the second smoke guide channels 311 formed by each group of the second filtering assembly 3 are all interconnected. In this way, the design of the multiple groups of the first filtering assembly 2 and the multiple groups of the second filtering assembly 3 can prolong the channel lengths of the first smoke guide channel 211 and the second smoke guide channel 311, prolong the passing time of the smoke in the high-efficiency smoke filtering device 10, make the smoke make sufficient contact with the multiple groups of the first filtering assembly 2 and the multiple groups of the second filtering assembly 3, and increase the number of collisions between the smoke and the multiple groups of the first filtering assembly 2 and the multiple groups of the second filtering assembly 3, which is beneficial to the smoke being fully purified, thereby improving the smoke filtering effect.

[0069] Please refer to Figure 2, Exemplarily, there are two sets of the first filtering components 2. One set of the first filtering components 2 is disposed adjacent to the first smoking port 131, and the other set of the first filtering components 2 is disposed adjacent to the first exhaust port 121. There are two sets of the second filtering components 3. One set of the second filtering components 3 is disposed adjacent to the first smoking port 131, and the other set of the second filtering components 3 is disposed adjacent to the first exhaust port 121, so that the two sets of the first filtering components 2 and the two sets of the second filtering components 3 are evenly arranged in the accommodation cavity 11. In this way, the airflow distribution of the smoke in the accommodation cavity 11 is uniform, and the problem of poor smoke treatment effect caused by too fast or too slow airflow speed can be effectively avoided. At the same time, the first exhaust port 121 is located in the second included angle space 5 formed by the other set of the first filtering components 2 and the other set of the second filtering components 3, which can reduce the resistance to the smoke caused by the improper position of the first exhaust port 121, effectively balance the airflow distribution of the smoke in the accommodation cavity 11, and enable the smoke discharged through the first smoke guiding channel 211 and the second smoke guiding channel 311 to smoothly discharge from the first exhaust port 121.

[0070] Further, the first smoking port 131 and the first exhaust port 121 are oppositely arranged. The two sets of the first filtering components 2 are symmetrically arranged with respect to the center of the accommodation cavity 11, and the two sets of the second filtering components 3 are symmetrically arranged with respect to the center of the accommodation cavity 11. In this way, the smoke can be evenly distributed in the accommodation cavity 11 and uniformly contact with the two sets of the first filtering components 2 and the two sets of the second filtering components 3, effectively balancing the working loads of each set of the first filtering components 2 and the second filtering components 3, avoiding the situation that some of the first filtering components 2 and the second filtering components 3 are prematurely damaged due to long-term high-load operation, effectively reducing the maintenance cost of the high-efficiency smoke filtering device 10, and prolonging the service life of the high-efficiency smoke filtering device 10.

[0071] Optionally, the cabinet body 1 is a square cabinet body, that is, the accommodation cavity 11 is a square cavity. The cabinet body 1 further includes a first end 14 and a second end 15 in the fourth direction F4. The two sets of the first filtering components 2 are located at the first end 14. One of the two sets of the first filtering components 2 and one of the two sets of the second filtering components 3 are located at the first end 14, respectively corresponding to and close to two corners of the first end 14. The other of the two sets of the first filtering components 2 and the other of the two sets of the second filtering components 3 are located at the second end 15, respectively corresponding to and close to two corners of the second end 15. The two sets of the first filtering components 2 and the two sets of the second filtering components 3 are both arranged at the four corner positions of the square accommodation cavity 11, which is beneficial to prolonging the passing time of the smoke in the accommodation cavity 11, strengthening the physical filtering effect on the smoke, and also being able to avoid the diffusion of the smoke in other places in the accommodation cavity 11, thereby improving the filtering effect of the smoke.

[0072] Exemplarily, since the cabinet body 1 is a square cabinet body and the accommodation cavity 11 is a square cavity, the first smoking port 131 and the first exhaust port 121 can be respectively located on both sides of the cabinet body 1 in the width direction. The two groups of first filtering components 2 are located at one end of the accommodation cavity 11 in the length direction, and the two groups of second filtering components 2 are located at the other end of the accommodation cavity in the length direction. Thus, the two groups of first filtering components 2 can be approximately located at two corners at one end of the accommodation cavity 11 in the length direction, while the two groups of second filtering components 2 can be approximately located at two corners at the other end of the accommodation cavity 11 in the length direction. In this way, the passing time of the delay in the accommodation cavity 11 can be extended as much as possible, thereby improving the filtering effect on the smoke.

[0073] Please refer to Figure 2 , in some embodiments, one of the two first filtering parts 21 is closer to the first smoking port 131, and one of the two second filtering parts 31 is closer to the first smoking port 131. Moreover, one of the first filtering parts 21 and one of the second filtering parts 31 are arranged to be closer to each other in the fourth direction F4. Thus, the distance formed between the one first filtering part 21 and the one second filtering part 31 is smaller, which can reduce the situation where the smoke directly passes through the gap between the two, so that the smoke can be blocked by the two and diffuse into the first smoke guiding channel 211 and the second smoke guiding channel 311.

[0074] It can be understood that the fourth direction F4 is a direction perpendicular to the first direction F1. For example, if the first direction F1 is the width direction of the cabinet body 1, then the fourth direction F4 is the length direction of the cabinet body 1; or if the first direction F1 is the length direction of the cabinet body 1, then the fourth direction F4 is the width direction of the cabinet body 1.

[0075] Optionally, one of the first filtering parts 21 and one of the second filtering parts 31 are connected to each other in the fourth direction F4, that is, there is no gap between them in the fourth direction F4. In this way, the smoke cannot pass through the gap between the two, so that as much smoke as possible can diffuse into the first smoke guiding channel 211 and the second smoke guiding channel 311, and further, the passing time of the smoke in the accommodation cavity 11 can be extended, which is beneficial to improving the filtering effect on the smoke.

[0076] Optionally, the included angle θ formed between the first filtering part 21 and the first direction F1 and the included angle β formed between the second filtering part 31 and the first direction F1 are both 30° to 60°, and the included angle θ and the included angle β are equal. At this time, the first smoke guiding channel 211 and the second smoke guiding channel 311 are at appropriate inclination angles, which can effectively reduce the vortex and turbulence phenomena of the smoke in the first smoke guiding channel 211 and the second smoke guiding channel 311, enabling the air flow to flow smoothly. At the same time, the inclined first smoke guiding channel 211 and second smoke guiding channel 311 can increase the flow area of the smoke and improve the smoke filtering effect. Therefore, the smoke filtering effect is the best at this time.

[0077] Exemplarily, the value of the included angle β can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc. Correspondingly, the value of the included angle θ can also be 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc. It can be specifically adjusted according to the actual situation, and this embodiment does not make specific limitations in this regard.

[0078] Optionally, the other first filtering part 21 among the two first filtering parts 21 and the other second filtering part 31 among the two second filtering parts 31 are arranged to be away from each other, so that the projection parts of the two first filtering parts 21 on the surface along the second direction F2 overlap, and the projection parts of the two second filtering parts 31 on the surface along the third direction F3 overlap. In this way, it can make the smoke move towards the first smoke guiding channel 211 and the second smoke guiding channel 311 as much as possible, thereby increasing the collision times of the smoke with the first filtering part 21 and the second filtering part 31, and effectively improving the smoke filtering effect.

[0079] That is to say, the projections of the two first filtering parts 21 along the second direction F2 are at least partially staggered, and the projections of the two second filtering parts 31 along the third direction F3 are at least partially staggered. In this way, when the two first filtering parts 21 are of equal length, it can be achieved that one of the first filtering parts 21 and one of the second filtering parts 31 are close to each other or even connected in the fourth direction F4, while the other first filtering part 21 and the other second filtering part 31 have a spacing in the fourth direction F4. As a result, the smoke can be blocked by the one first filtering part 21 and the one second filtering part 31 and then pass through the first smoke guiding channel 211 and the second smoke guiding channel 311 respectively formed between the two first filtering parts 21 and the two second filtering parts 31, thereby achieving the effect of extending the passing time of the smoke in the accommodation cavity 11.

[0080] Optionally, both the first filtering part 21 and the second filtering part 31 can be in a plate-like structure, a strip-like structure or a block-like structure. Moreover, the materials of the first filtering part 21 and the second filtering part 31 are both fireproof and flame-retardant materials. This fireproof and flame-retardant material can make the high-efficiency smoke filtering device 10 have stronger fire resistance and flame retardancy, effectively prevent the occurrence of fire accidents, and improve the safety of the high-efficiency smoke filtering device 10.

[0081] The following briefly describes the passing process of smoke in the accommodation cavity 11:

[0082] Combined with Figure 2 and Figure 3 , Figure 2 The dotted arrows in show the passing direction of the smoke in the accommodation cavity 11. The fan 401 located above the high-efficiency smoke filtering device 10 is started, and the smoke generated during cooking is attracted by the vertical attraction of the fan 401 and enters the high-efficiency smoke filtering device 10 from the first smoke suction port 131. First, the smoke enters the first included angle space 4 formed by the second filtering component 3 and the first filtering component 2. At this time, the smoke will contact and be filtered by the first filtering component 2 and the second filtering component 3, and then pass through the next group of the first filtering component 2 and the second filtering component 3 to contact and be filtered. Finally, the filtered smoke enters the second included angle space 5 and is discharged from the first smoke exhaust port 121.

[0083] Alternatively, the smoke will be affected by the resistance of the first filtering component 2 and the second filtering component 3 and enter the first smoke guiding channel 211 and the second smoke guiding channel 311, and move in the direction of the dotted arrows in the first smoke guiding channel 211 and the second smoke guiding channel 311 as shown in Figure 2 . Also, because the vertical attraction of the fan 401 always exists, the moving direction of the smoke will be affected at this time, so that the smoke can continuously collide with the first smoke guiding channel 211 and the second smoke guiding channel 311, that is, the number of collisions between the smoke and the two first filtering parts 21 and the two second filtering parts 31 increases, thereby prolonging the passing time of the smoke in the high-efficiency smoke filtering device 10, and thus improving the filtering effect of the smoke.

[0084] Both of the above two situations can achieve effective filtering of the smoke by the two first filtering components 2 and the two second filtering components 3.

[0085] In the second aspect, please refer to Figure 3 , Figure 3Internal structural view of the integrated cooking stove with oil fume purification disclosed in the embodiments of the present application.
