Description

Technical Field

[0001] The utility model belongs to the technical field of kitchenware manufacturing, and particularly relates to a smoke collecting hood. Background Art

[0002] Integrated stove is a common household appliance in the kitchen market. It is generally composed of a smoke hood, a gas stove and a combination cabinet. Compared with the traditional split kitchen design, the integrated stove has the following advantages: the structure is more compact, the space utilization rate is high, and the kitchen space can be effectively saved; it integrates multiple functions such as cooking, smoke exhaust, storage, etc., with complete functions and more convenient to use; the design is neater and more beautiful, and the kitchen has a good decorative effect. The core components of the integrated stove are the gas stove and the smoke hood. Among them, the gas stove is mainly used for cooking. Considering the simultaneous use of multiple stoves and the smoke exhaust effect, the layout of the gas stove in the integrated stove is very critical. The smoke hood plays an important role in the kitchen. Its main function is to collect and filter oil smoke and odor, and discharge the oil smoke to the outside, which can effectively improve the air quality of the kitchen, make the kitchen air fresh and clean, and protect the kitchen walls and furniture from oil smoke pollution.

[0003] Utility model patent CN215295002U discloses an integrated stove with adjustable smoke hood angle, which includes a stove, a bellows and a smoke hood are installed in front of the upper end of the stove, and the smoke hood is connected to the bellows through an angle adjustment structure, the angle adjustment structure includes a left rotating shaft and a right rotating shaft arranged on both sides of the smoke hood, and a rotating table located on both sides above the bellows, the left rotating shaft and the right rotating shaft pass through the rotating hole in the rotating table and protrude from the rotating hole; a driving mechanism is arranged on one side of the smoke hood, and its main shaft extends into and is clamped in the left rotating shaft, and the driving mechanism drives the left rotating shaft and the right rotating shaft to rotate along the rotating hole through the rotation of the main shaft, thereby driving the smoke hood to swing back and forth and adjusting the front and rear angles of the smoke hood. The utility model can change the distance between the smoke hood and the stove according to the actual cooking needs of the user, so that the smoke outlet opened on the inner end surface of the smoke hood can achieve the best match with the stove, and the oil smoke can be absorbed and discharged to the maximum extent.

[0004] However, in order to facilitate cooking, the use of pots requires sufficient operating space. This is specifically reflected in the structure that a certain distance needs to be maintained between the stove and the bellows in the above-mentioned utility model integrated stove. This means that in order to make the smoke outlet opened on the inner end face of the smoke hood to achieve the best match with the stove and absorb the oil fume to the maximum extent, the smoke hood rotatably connected to the upper end of the bellows needs to be long enough to cover the top of the stove after rotation to absorb the oil fume. However, if the smoke hood is too long, it will increase the load-bearing capacity of the angle adjustment structure, so the equipment loss is large and the service life is short. At present, this type of integrated stove on the market mostly uses a short-distance smoke hood to ensure the service life of the equipment. On this basis, the technical problem of poor oil fume absorption effect caused by the position deviation between the smoke outlet and the stove is alleviated by selecting a high-power range hood. However, from the actual use effect, for cooking methods with high oil fume volatility such as stir-frying and frying, the oil fume absorption effect is still not ideal, and the energy consumption is high. Utility Model Content

[0005] The purpose of the utility model is to provide a fume hood with a large cooking space and good fume absorption effect, which is specifically achieved through the following technical solutions:

[0006] A fume collecting hood comprises a box body for collecting oil fume, one end of the box body is connected through a supporting pipe for fixing the box body.

[0007] Compared with the prior art, the present application is based on an overall consideration of the space occupied by the smoke hood, and changes the previous connection method in which the box is directly connected to the bellows, but instead separately sets a support pipe structure on the box. On the one hand, the support pipe can conduct the oil smoke in the box and serve as an oil smoke channel; on the other hand, the support pipe can also fix the box so that it is placed above the gas stove. On this basis, the present application also makes a special design for the position of the support pipe - that is, the support pipe is set at one end of the box, which will greatly reduce the kitchen space occupied by the smoke hood, so correspondingly, the operating space of the pot is larger. In addition, compared with the design of the folding smoke hood in the prior art, the smoke hood box of the present application can be directly set directly above the gas stove burner, so the oil smoke absorption is more accurate and the smoke purification effect will be better.

[0008] Preferably, the lower surface of the box body includes a smoke guide portion for collecting oil smoke.

[0009] In this technical solution, by arranging a smoke guide portion on the lower surface of the box body, it is possible to avoid the diffusion of oil smoke and keep the kitchen air fresh on the basis of the above-mentioned box body position design.

[0010] Preferably, the smoke guiding portion comprises a smoke guiding port, and an oil net arranged on the surface of the smoke guiding port.

[0011] In this technical solution, by setting an oil net on the surface of the smoke guide port, grease, impurities and smoke particles in the smoke can be prevented from entering the support pipe and then accumulating and corroding the inner surface of the support pipe. Therefore, it helps to extend the service life of the support pipe, and the smoke hood is easier to clean and maintain.

[0012] Preferably, the height of the end of the lower surface close to the user is higher than the height of the end of the lower surface away from the user.

[0013] In this technical solution, by tilting the lower surface, on the one hand, the collection surface of oil smoke is increased, so the efficiency of oil smoke absorption is higher; on the other hand, the oil smoke can be guided to flow into the box along the lower surface, thereby reducing the possibility of oil smoke overflow and keeping the kitchen environment clean.

[0014] Preferably, the box body is also provided with a smoke sensing device for detecting the concentration of oil smoke.

[0015] In this technical solution, by arranging a smoke sensor on the box body, the oil fume concentration can be accurately detected in real time. When oil fume is detected, the smoke sensor can cooperate with the box body to achieve the oil fume purification effect.

[0016] As a further preference, the smoke sensing device includes a proximal oil smoke sensor arranged on the lower surface.

[0017] After being generated, oil smoke will rise upward first. Therefore, in this technical solution, by setting a proximal oil smoke sensor on the lower surface, the oil smoke can be detected more sensitively, avoiding smoke interference caused by other reasons, and the detection accuracy is higher.

[0018] Preferably, the box body further comprises a front surface which is longitudinally arranged on a side close to a user and whose lower end is connected to the lower surface.

[0019] In order to prevent the oil stains entering the box from remaining on its inner surface, in this technical solution, the dead angle inside the box can be reduced by setting the front surface, so the inside of the box will be cleaner. In addition, the design of the front surface will effectively increase the capacity of the box, so the oil fume purification efficiency is higher.

[0020] Preferably, the smoke sensing device further comprises a distal oil smoke sensor arranged on the front surface.

[0021] After the oil smoke is generated, it will rise upwards first. At first, the proximal oil smoke sensor will be triggered first based on its location setting; then the oil smoke will continue to rise along the lower surface and finally escape near the front surface. Therefore, in this technical solution, by setting a distal oil smoke sensor on the front surface, the concentration of the escaping oil smoke can be detected.

[0022] Preferably, the smoke collecting hood further comprises a driving device for driving the supporting pipe to rotate.

[0023] In this technical solution, by setting a driving device, the box can be covered directly above the pot that generates oil smoke, so the smoke collection hood can collect oil smoke with higher accuracy and better smoke purification effect. In addition, after cooking, the driving device can also rotate the box to other positions to facilitate cleaning of the gas stove.

[0024] Preferably, a transmission device cooperating with the driving device is further provided at one end of the supporting pipe away from the box body.

[0025] In principle, the transmission device can be set at any position, but in this article, by setting it at the end of the support pipe away from the box body, the connection relationship between the support pipe and the box body can be fully utilized to indirectly drive the box body to rotate, and the overall operation stability of the smoke hood is higher and the sealing is better.

[0026] Compared with the prior art, the utility model has the following beneficial effects:

[0027] Compared with the prior art, the present application is based on the overall consideration of the space occupied by the smoke hood, and changes the previous connection mode of the box directly connected to the bellows, but sets a supporting pipe structure on the box separately. On the one hand, the supporting pipe can conduct the oil smoke in the box and play the role of the oil smoke channel; on the other hand, the supporting pipe can also fix the box so that it is placed above the gas stove. On this basis, the present application also makes a special design for the position of the supporting pipe, that is, the supporting pipe is set at one end of the box, which will greatly reduce the kitchen space occupied by the smoke hood, so that the corresponding pot operation space is larger. In addition, the present application can accurately detect the oil smoke concentration in real time by setting a smoke sensing device on the box; further, by setting a driving device and a transmission device, the position of the box can be adjusted with the smoke sensing device, so that during the cooking process, the smoke hood box can be directly set directly above the gas stove burner. Compared with the design of the smoke hood folding in the prior art, the oil smoke absorption is more accurate and the smoke purification effect will be better. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The utility model is further described below in conjunction with the drawings and specific embodiments of the specification. A person of ordinary skill in the art will be able to implement the utility model based on these descriptions. In addition, the embodiments of the utility model involved in the following description are usually only embodiments of a part of the utility model, rather than all of the embodiments. Therefore, based on the embodiments in the utility model, all other embodiments obtained by a person of ordinary skill in the art without making creative work should fall within the scope of protection of the utility model.

[0033] Example 1

[0034] See also Figure 1 This embodiment discloses a smoke collecting hood, comprising:

[0035] The box 1 for collecting oil smoke is in the shape of a right triangular prism in this embodiment, and includes a lower surface 11, a first surface and a second surface which are enclosed with the lower surface 11 to form a main part of the triangular prism and are arranged perpendicular to each other, and two side surfaces which are connected to the two ends of the lower surface 11, the first surface and the second surface respectively. In this embodiment, by setting the box 1 in the shape of a right triangular prism, on the one hand, the oil smoke collection space of the box 1 will be effectively increased; on the other hand, the formed box 1 will have higher stability. In order to increase the collection surface of oil smoke and improve the efficiency of oil smoke absorption, the height of the lower surface 11 close to the user is higher than the height of the lower surface 11 away from the user, and the second surface is arranged longitudinally.

[0036] The lower surface 11 of the box body 1 includes a smoke guide portion 111 for collecting oil smoke; the smoke guide portion 111 includes a smoke guide port 1111 and an oil net 1112 arranged on the surface of the smoke guide port 1111. By arranging the oil net 1112 on the surface of the smoke guide port 1111, grease, impurities and oil smoke particles in the oil smoke can be prevented from entering the interior of the support pipe 2, and then accumulating and corroding on the inner surface of the support pipe 2. Therefore, it helps to extend the service life of the support pipe 2, and the smoke hood is easier to clean and maintain.

[0037] The smoke hood of this embodiment further includes a support pipe 2, one end of which is connected to the side surface of the box body 1, and the other end of which is used to connect to the bellows. In this embodiment, by installing the support pipe 2 on the side surface of the box body 1, not only can the box body 1 be supported, but also the installation space occupied by the smoke hood during use can be reduced, thereby increasing the usable area of ​​the table. In addition, the support pipe 2 can also serve as a smoke guide pipe to guide the oil smoke collected by the smoke guide port 1111 to the bellows, and then to the outside.

[0038] The smoke hood of this embodiment also includes a smoke sensing device 12 disposed on the housing 1 and used to monitor the concentration of oil smoke. The smoke sensing device 12 includes two proximal oil smoke sensors 121, which are respectively disposed at the end of the lower surface 11 away from the user and the end close to the user. Since the lower surface 11 is tilted in this embodiment, the two proximal oil smoke sensors 121 are at different heights in the longitudinal direction. Therefore, the proximal oil smoke sensor 121 disposed on the side away from the user is closer to the gas stove and can detect the oil smoke more sensitively, thus avoiding smoke interference caused by other reasons and achieving higher detection accuracy. The proximal oil smoke sensor 121 disposed on the side close to the user can detect oil smoke when there is a lot of oil smoke.

[0039] On this basis, in order to increase the flexibility and intelligence of the location setting of the box body 1, the smoke hood of this embodiment is also provided with a driving device for driving the support pipe 2 to rotate; accordingly, the end of the support pipe 2 away from the box body 1 is also provided with a transmission device that cooperates with the driving device. By setting the transmission device at the end of the support pipe 2 away from the box body 1, the connection relationship between the support pipe 2 and the box body 1 can be fully utilized to indirectly drive the box body 1 to rotate, and the overall operation stability of the smoke hood is higher and the sealing is better.

[0040] Example 2

[0041] This embodiment discloses a smoke collecting hood, comprising:

[0042] The box 1 for collecting oil smoke is a trapezoidal body in this embodiment, which includes a front surface 13 arranged longitudinally, and a rear surface arranged in parallel with the front surface 13. The bottom end of the front surface 13 is connected with the bottom end of the rear surface to form a lower surface 11. In the longitudinal direction, the height of the bottom end of the front surface 13 is higher than the height of the bottom end of the rear surface. Therefore, this also means that the height of the end of the lower surface 11 close to the user in this embodiment is higher than the height of the end of the lower surface 11 away from the user. In this embodiment, by setting the front surface 13, the dead angle inside the box 1 can be reduced, so the cleanliness inside the box 1 will be higher. In addition, the design of the front surface 13 will effectively increase the accommodating volume of the box 1, so the oil smoke purification efficiency is higher.

[0043] The lower surface 11 of the box body 1 includes a smoke guide portion 111 for collecting oil smoke; the smoke guide portion 111 includes a smoke guide port 1111 and an oil net 1112 arranged on the surface of the smoke guide port 1111. By arranging the oil net 1112 on the surface of the smoke guide port 1111, grease, impurities and oil smoke particles in the oil smoke can be prevented from entering the interior of the support pipe 2, and then accumulating and corroding on the inner surface of the support pipe 2. Therefore, it helps to extend the service life of the support pipe 2, and the smoke hood is easier to clean and maintain.

[0044] The smoke hood of this embodiment also includes a support pipe 2, the upper end of the support pipe 2 is connected to the lower surface 11, and the part of the support pipe 2 connected to the lower surface 11 is distributed on one side of the lower surface 11. The other end of the support pipe 2 is used to connect the bellows. Compared with the design of setting the support pipe 2 on the side surface of the box 1 in Example 1, by installing the support pipe 2 on the lower surface 11 of the box 1, the weight bearing and support of the box 1 can be better achieved in this embodiment, so the operation stability of the box 1 is higher. By setting the support pipe 2 at one end of the box 1, the installation space of the smoke hood will be reduced and the usable area of ​​the countertop will be increased. In addition, the support pipe 2 can also be used as a smoke guide pipe to guide the oil smoke collected by the smoke guide port 1111 to the bellows, and then discharged to the outside.

[0045] The smoke hood of this embodiment also includes a smoke sensing device 12 arranged on the housing 1 and used to monitor the oil fume concentration. The smoke sensing device 12 includes a proximal oil fume sensor 121 arranged at the end of the lower surface 11 away from the user. By arranging the proximal oil fume sensor 121 at the designated position, the distance between the proximal oil fume sensor 121 and the cookware can be shortened, so the oil fume concentration detection is more accurate and the oil fume can be detected in time. The smoke sensing device 12 also includes a distal oil fume sensor 122 arranged on the front surface 13. The distal oil fume sensor 122 is located at the oil fume escape position, so it can cooperate with the proximal oil fume sensor 121 to measure the oil fume concentration range in the oil fume dispersion area. On this basis, in order to increase the flexibility and intelligence of the position setting of the housing 1, the smoke hood of this embodiment is also provided with a driving device for driving the support pipe 2 to rotate; accordingly, the support pipe 2 is also provided with a transmission device that cooperates with the driving device at the end away from the housing 1. By arranging the transmission device at the end of the support pipe 2 away from the box body 1, the connection relationship between the support pipe 2 and the box body 1 can be fully utilized to indirectly drive the box body 1 to rotate, and the overall operation stability of the smoke hood is higher and the sealing is better.
