Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cooking equipment, and in particular to an air inlet plate, a machine head and an integrated stove. Background Art
[0002] When the current integrated stove cooking equipment is in use, oil smoke will escape from the edge area, making it difficult to fully collect the oil smoke. The reason for the insufficient oil smoke collection is that for most integrated stoves, the burners are generally distributed on both sides of the stove, so the oil smoke generated during cooking is generally located on both sides of the stove. The air collection port inside the integrated stove is generally located in the middle of the machine head. During the cooking process, if the air hole area of the oil smoke extraction device on the machine head is consistent, the gas flow rate passing through the air hole near the middle per unit time will be higher than the gas flow rate passing through the air hole at the edge. In addition, the gas flow rate passing through the air hole per unit time will gradually decrease as the distance between the air hole and the air inlet increases. Therefore, the oil smoke from the air hole at the edge is easy to escape from the air hole at the edge.
[0003] In traditional product upgrades, in order to prevent oil smoke from escaping and improve the oil smoke absorption effect of integrated stoves, the method of increasing the air volume and air pressure of the fan is usually adopted. However, the increase in the air volume and air pressure of the fan system will inevitably cause the fan system to generate greater noise, causing new defects. Utility Model Content

[0021] Example 1
[0022] Combined with Figure 1-4 The present embodiment proposes an air inlet plate, which is located on the head of the integrated stove above the cooktop, and includes a plate body 13. The plate body 13 is provided with a plurality of penetrating mesh holes 131, and the area of the mesh holes 131 gradually increases in the direction of increasing height of the plate body 13; and / or gradually increases from the center line A of the plate body 13 to both sides of the center line, wherein the distance from the center line A to the left and right sides of the plate body 13 in the horizontal direction is equal.
[0023] In order to solve the technical problem that oil smoke is easy to escape and cannot be fully collected when using traditional integrated stoves, an air inlet plate in this embodiment improves the layout of the mesh holes 131 so that the flow rate of gas passing through the mesh holes 131 at the edge of the plate body 13 per unit time is relatively increased, thereby more effectively collecting oil smoke and preventing it from escaping.
[0024] In this embodiment, the shape of the mesh 131 is not limited, that is, the shape of the mesh 131 can be set according to actual conditions, for example, the mesh 131 can be one or a combination of any regular or irregular geometric shapes such as circular, rectangular, diamond, etc. The setting of the mesh 131 is mainly used to divide the airflow in the integrated stove head into independent units. The flow rate of the airflow in the unit is relatively higher, which can ensure the fume extraction effect. It is conceivable that the plate body 13 with the mesh 131 can also prevent debris from being sucked into the head.
[0025] The improvement of the layout of the mesh 131 in this embodiment is mainly achieved by changing the area of the mesh 131 at different positions. The area of the mesh 131 gradually increases along the direction of the height increase of the plate body 13, wherein the height direction is consistent with the height direction when the integrated stove is normally used. That is, when the plate body 13 is assembled, the area of the mesh 131 with a lower height that is relatively closer to the stove is smaller, and the area of the mesh 131 with a higher height away from the stove is larger. In this way, the flow rate and flow rate of the mesh 131 at a lower height can be kept as balanced as possible with the gas flow rate and flow rate of the mesh 131 at a higher height and close to the edge. It can be understood that, relative to the case where the area of the mesh 131 is consistent, this implementation method makes the gas flow rate and flow rate of the mesh 131 at a higher height and close to the edge obtain a certain degree of improvement, which is conducive to preventing oil smoke from escaping from the top of the machine head.
[0026] Similar to the above embodiment, in one embodiment, the center line A of the plate body 13 gradually increases toward both sides of the center line, wherein the center line A is the center line extending in the height direction in the middle of the machine head when the integrated stove is in normal use, and the distance from the center line A to the left and right sides of the plate body 13 in the horizontal direction is equal. In this embodiment, the area of the mesh 131 near the burners on both sides and the edge of the plate body 13 is relatively larger, and the area of the mesh 131 located between the burners on both sides is relatively smaller. In this way, the gas flow rate and flow velocity of the mesh 131 near the burners and located at the edges of the plate body 13 on both sides can be relatively larger, and it is easier to prevent oil smoke from escaping from both sides of the machine head.
[0027] The above two implementation modes can be combined with each other to Figure 1For example, in this embodiment, the horizontal line of the center of the mesh 131 at the lowest height is taken as the horizontal axis, and the intersection of the horizontal axis and the center line A is taken as the origin. From the origin to the higher height and both sides of the center line A, the area of the mesh 131 becomes larger and larger. In this way, the flow rate of gas passing through the mesh 131 at the top and both sides of the plate body 13 per unit time can be relatively increased. Under the condition that the power of the integrated stove remains unchanged and the total amount of air intake remains the same, this embodiment can more effectively collect oil smoke and prevent oil smoke from escaping.
[0028] The spacing between adjacent meshes 131 may be the same or different. The spacing between adjacent meshes 131 refers to the horizontal spacing between the meshes 131, or the spacing along the extension direction of the center line A, wherein the horizontal direction is the left-right direction of the integrated stove in normal use.
[0029] In some embodiments, when the spacing between adjacent meshes 131 is different, similar to the technical effect of the aforementioned embodiment, in addition to controlling the air intake of different areas of the panel body 13 by adjusting the area of the meshes 131, the air intake of different areas of the panel body 13 can also be controlled by adjusting the spacing between the meshes 131, that is, the air intake of different areas of the panel body 13 is controlled by the different densities of the meshes 131 in different areas of the panel body 13. Therefore, in one embodiment, the spacing between the meshes 131 in the lower middle area of the panel body 13 can be set larger, while the spacing between the meshes 131 in the top and edge areas of the panel body 13 can be set smaller, thereby achieving more effective collection of oil smoke at the edge to prevent oil smoke from escaping when the power of the integrated stove remains unchanged and the total amount of air intake remains consistent.
[0030] In some embodiments, there is a center distance a between adjacent meshes 131 in the horizontal direction, and the center distance a of at least some of the meshes 131 arranged in the horizontal direction is equal. In this case, the density of the meshes 131 in the horizontal direction of at least some areas is kept consistent, so that it is easier to determine the air volume of the area during design, and when adjusting in the design stage, the variables that need to be adjusted are reduced, that is, it is easier to design, and the air inlet plate as a whole is relatively more beautiful.
[0031] Similarly, in some embodiments, there is a center distance b between the adjacent meshes 131 in the extension direction of the center line A, and the center distance b of the meshes 131 arranged at least partially in the extension direction of the center line A is equal. At this time, the density of the meshes 131 in the extension direction of the center line A in at least some areas is consistent, and the plate body 13 may be tilted, but the plate body 13 is still mainly arranged longitudinally as a whole. Therefore, the center distance b of the meshes 131 in the extension direction of the center line A represents the density of the meshes 131 in the height direction of the integrated stove to a certain extent. This makes it easier to determine the air volume in different height areas during design, and reduces the variables that need to be adjusted during adjustment in the design stage, which is more convenient for design, and the air inlet plate as a whole is relatively more beautiful.
[0032] Example 2
[0033] Combined with Figure 1-4 The present embodiment proposes a head, comprising the air inlet plate recorded in the technical solution of Embodiment 1, and also comprising a shell 10, a fan 11 and a smoke collecting plate 12; the shell 10 and the smoke collecting plate 12 constitute a smoke collecting chamber, the fan 11 is fixed in the smoke collecting chamber, and the smoke collecting plate 12 is provided with a smoke collecting port 120 connected to the air inlet of the fan 11, and the smoke collecting port 120 is located in the middle of the smoke collecting plate 12, and a plate body 13 is fixed on the shell 10, and the plate body 13 is located on the side of the smoke collecting plate 12 away from the fan 11.
[0034] The head of this embodiment is located at the upper part of the integrated stove. During normal operation, the smoke passes through the mesh 131 and enters the air inlet of the fan 11 through the smoke collecting port 120 on the smoke collecting plate 12. Among them, the fan 11 is placed in the smoke collecting chamber formed by the shell 10 and the smoke collecting plate 12. In this embodiment, the installation position of the fan 11 is raised. Compared with the structural form of the traditional integrated stove, the fan 11 of this embodiment is closer to the stove, which makes the flow path of the airflow shorter and makes the energy dissipation of the airflow in the process of flowing to the fan 11 smaller, thereby improving the oil fume absorption effect to a certain extent. With the air inlet plate of Example 1, it can absorb oil fume more fully, reduce the escape of oil fume at the edge of the head, and improve the oil fume absorption effect of the integrated stove.
[0035] In order to further improve the smoke absorption effect of the head, in a further embodiment, at least part of the smoke collecting plate 12 is recessed in the air inlet direction of the smoke collecting port 120 to form a recessed portion 121, and the smoke collecting plate 12 forms a smoke collecting channel 20 with a cross section gradually converging in the direction of the smoke collecting port 120 through the recessed portion 121. This embodiment further improves the smoke collecting plate 12, so that the smoke collecting channel 20 formed by the recessed smoke collecting plate 12 plays a smoke collecting and diverting role similar to a funnel. When the fan 11 is working, the cross-sectional area from the plate body 13 to the air inlet of the fan 11 gradually decreases, forming a Venturi phenomenon. The plate body 13 is away from the smoke collecting plate 12, that is, the air flow velocity on the outside of the plate body 13 is relatively slow. Therefore, the pressure on the outside of the plate body 13 is relatively large. The smoke collecting port 120 has a relatively smaller cross-sectional area and is closer to the air inlet of the fan 11, so the air flow velocity is faster, resulting in a relatively smaller air flow pressure. Therefore, the pressure difference between the plate body 13 and the air inlet of the fan 11 generates an external suction force, thereby more effectively collecting oil smoke and preventing oil smoke from escaping.
[0036] Furthermore, in this embodiment, the smoke collecting port 120 is located in the middle of the smoke collecting plate 12. Since smoke enters the air inlet from the smoke collecting port 120, the area where the air inlet of the fan 11 forms suction force to the outside is also located in the middle of the smoke collecting plate 12. Therefore, when the head is working, the suction wind force of the head to the left and right burners is basically the same, and the oil smoke generated by the cooking pots on the left and right sides can be evenly extracted, thereby improving the smoke collecting effect and allowing the oil smoke to be more fully collected.
[0037] In order to further prevent the escape of oil smoke, in one embodiment, at least part of the top of the housing 10 extends forward, at least part of the smoke collecting plate 12 near the top of the housing 10 extends forward, and at least part of the plate body 13 near the top of the housing 10 is fixedly connected to the part of the top of the housing 10 extending forward, so that the plate body 13 is tilted, and the projection of the plate body 13 to the stove at least partially overlaps with the stove. The front side refers to the side closer to the stove or the side closer to the operator when the integrated stove is in normal use.
[0038] This embodiment makes the top of the machine head closer to the upper space of the stove, and the upper space of the stove is the main area where oil smoke escapes, so the plate body 13 and the smoke collecting area formed by the smoke collecting plate 12 can cover as much of the area where oil smoke drifts upward as possible, thereby improving the collection effect of oil smoke. Combined with the setting of the smoke collecting channel 20 in the previous embodiment, this embodiment allows the part of the smoke collecting channel 20 close to the top of the machine head to cover as much of the area where oil smoke drifts upward as possible, thereby improving the collection effect of oil smoke.
[0039] In some embodiments, a filter 110 is fixedly installed at the smoke collection port 120, and the area of the filter holes on the filter 110 is smaller than the minimum area of the mesh 131, thereby preventing non-oil smoke impurities smaller than the size of the mesh 131 from being sucked into the integrated stove.
[0040] Example 3
[0041] Combined with Figure 1-4 This embodiment proposes an integrated stove, including a stove top, and the machine head recorded in the technical solution of Example 2 is located on the stove top.
[0042] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creative design without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
