Description

Smoke exhaust pipe structure of integrated stove

Technical Field

The utility model relates to the technical field of integrated cookers, in particular to a smoke exhaust pipe structure of an integrated cooker, which can reduce the loss of pneumatic performance and reduce noise in the smoke exhaust process.

Background

An integrated kitchen range is a kitchen appliance integrating multiple functions. Because of the characteristics of space saving, elegant appearance and the like, the utility model is popular with a plurality of consumers. Different from the traditional range hood, the smoke exhaust pipe of the smoke collection cavity in the integrated kitchen is positioned below the kitchen body, and the special structure of the smoke exhaust pipe can cause that the section of distance between the oil smoke and the smoke exhaust pipe from the outlet of the volute can be subjected to larger resistance in the air outlet process, so that the advantages and disadvantages of the design of the connecting structure between the air outlet of the volute and the smoke exhaust pipe can directly influence the loss of the air performance and the noise of the oil smoke in the exhaust process. If the loss of the aerodynamic performance of the oil smoke is too large in this process, the blower in the volute consumes more electric energy when discharging the same amount of gas (oil smoke).

Different users, integrated kitchen reservation space position is different in its kitchen, consequently the export of discharging fume the pipe can be located the left side of integrated kitchen, also can be located the right of integrated kitchen, so horizontal one can control the direct pipe of discharging fume on integrated kitchen when manufacturing, it all has the export about, and the spiral case then sets up in the centre of discharging fume the pipe and through the pipe middle reservation interface connection pipe of discharging fume, be equipped with the wind direction converter that can the horizontal hunting in the middle of discharging fume the pipe, the wind direction converter includes the middle guide plate of passing through axis of rotation and tub connection of discharging fume, thereby can realize the conversion of controlling the passageway air-out according to actual conditions.

But the volute air outlet in the middle of the smoke exhaust pipe is not symmetrical, and in the left and right directions of the smoke exhaust pipe, oil smoke in the volute flows into the smoke exhaust pipe after passing through an anticlockwise or clockwise motion track, so that the oil smoke at two sides of the volute air outlet has a speed difference, and pressure difference is generated at two sides due to the existence of the speed difference. In order to reduce the loss of oil smoke performance and noise in the emission process, the plate lines (parameters such as curve radius, radian and arc length) of the guide plates are different for different pressures, the wind direction is switched by the swingable guide plates only using the same plate line, the pressures on two sides of a volute air outlet are difficult to take into consideration, the specific plate line guide plates can only make optimal design on one side of the guide plates, or the balance of two sides is considered to take the design of a median, and the two sides are difficult to optimize.

In addition, the side walls of the two sides of the air outlet of the volute are not vertically connected with the smoke exhaust pipe, airflow on the two sides of the volute cannot be vertically guided into the smoke exhaust pipe, and the smoother (tangent) the connection part of the guide plate and the air outlet of the volute is, the smaller the loss of aerodynamic performance is, and the smaller the noise is. And use a can swing guide plate can't give consideration to both sides can both realize smooth connection simultaneously, then both sides can not accomplish the optimum simultaneously yet.

And smoke outlets are reserved on two sides of the integrated kitchen range in some kitchens during decoration, and for some integrated kitchen ranges capable of automatically selecting from which side to discharge smoke according to conditions in the using process, for example, in the Chinese patent with the patent number of 209084849U, a guide plate of the integrated kitchen range can automatically turn according to the distribution condition of the oil smoke at a volute outlet, and the specific expression shows that the oil smoke at which side is invaded and invaded towards which side. The integrated kitchen of this kind of structure, if in the use (come out from the spiral case air outlet) oil smoke for a moment the left side is many, for a moment the right side is many, so the guide plate will make a round trip to switch between controlling (the process gas velocity of flow of switching can short-term reduce) for (in the spiral case) centrifugal fan's air-out has periodic pressure pulsation, and the pivoted guide plate takes place to collide with and produce the noise problem along with the oil smoke distributes and takes place between the pipe of discharging fume very easily simultaneously.

Therefore, there is a need for a range integrated smoke evacuation tube structure that reduces aerodynamic performance losses and reduces noise during smoke evacuation.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications without inventive contribution to the present embodiment as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.

Example 1:

as shown in fig. 1 to 3, there is shown an integrated range that employs a smoke exhaust pipe structure including a scroll case 200 and a smoke exhaust pipe 100 located below the scroll case 200. The smoke exhaust pipe 100 is a straight pipe horizontally placed, and has a rectangular cross section. The middle of the smoke exhaust pipe 100 is provided with a smoke inlet 110, the smoke inlet 110 is arranged on the top wall of the smoke exhaust pipe 100, the smoke inlet 110 is connected with an air outlet 210 of the volute 200 through a flange (see fig. 6), and two ends of the smoke exhaust pipe 100 are respectively provided with a smoke exhaust port 130.

The smoke exhaust pipe 100 is provided with a flow guide assembly for selectively guiding the smoke from the smoke inlet 110 to one of the smoke exhaust ports 130 according to the requirement (a smoke exhaust pipeline reserved in a kitchen). The flow guide assembly includes a first assembly 300 and a second assembly 400 that are detachably mounted. The first assembly 300 includes a first baffle 310 and a first support bracket 320 for placing the first baffle 310 from the smoke exhaust 130 thereof within the smoke exhaust 100. The second assembly 400 includes a second baffle 410 and a second support bracket 420 for placing the second baffle 410 from another of the smoke evacuation ports 130 in the smoke evacuation duct 100.

The first guide plate 310 and the second guide plate 410 have the same or different plate-shaped lines, so that when the two guide plates are respectively connected with the air outlet 210 of the scroll casing 200, the oil smoke can be smoothly guided to the corresponding smoke outlet through the different plate-shaped lines, thereby reducing the loss of pneumatic performance and reducing noise.

The baffle plate type line at least comprises one of a circular arc, a quadratic curve, a Bezier curve or a multi-segment line, or the combination of any curve and a straight line.

The center of a circle corresponding to an arc line segment of a plate type line of the existing swing guide plate of the integrated stove is a rotation center, and the rotation center is necessarily arranged in an air outlet of a smoke exhaust pipe or a volute, so that the range of the selectable arcs of the plate type of the guide plate is limited. In the embodiment, two guide assemblies which are independent from each other are adopted, the type of the guide plate is not limited, and the circle center corresponding to the arc line segment may not be located in the smoke exhaust pipe 100 or the air outlet 210 of the volute 200. When the smoke exhaust device is used, one of the guide plates can be placed in the smoke exhaust pipe 100 according to needs only through the support frame, and the other guide plate is taken out, so that a smoke exhaust space is reserved.

To further reduce the loss of air performance during the smoke evacuation process, the upper end of the deflector is smoothly connected to the outlet 210 of the volute 200 while the air flow is guided by the deflector. When the air flow is guided by the guide plate, the lower end of the guide plate is tangent to the bottom wall of the smoke exhaust pipe 100.

In this embodiment, the scroll casing 200 has an upper structure as shown in fig. 6. In the volute 200 with the structure, the wall of the air outlet 210 on the inner side and the wall of the air outlet 210 on the outer side are both perpendicular to the smoke exhaust pipe 100, namely the angles 1 and 2 are both 90 degrees in the figure. It should be noted that, here, the wall of the outlet 210 located at the inner side and the wall of the outlet located at the outer side are determined by the center of the scroll 200, and the air flow from the center of the scroll 200 to the outlet 210 passes through a counterclockwise pipeline, so that the outlet 210 is defined as being located at the inner side near the center of the scroll 200, and the outlet 210 is defined as being located at the outer side away from the center of the scroll 200.

More specifically, in this embodiment, the molded line of the first flow guide plate 310 is a quarter of a great arc, the upper end of the first flow guide plate 310 is smoothly connected to the wall of the volute 200 outside the air outlet 210, and the lower end of the first flow guide plate 310 is tangent to the bottom wall of the smoke exhaust pipe 100 to be smoothly connected. The second guide plate 410 has a shape line formed by connecting a straight line segment and a quarter of a small arc, wherein the straight line segment is located at the upper end of the second guide plate 410 and is smoothly connected with the wall of the inner side of the air outlet 210 of the scroll casing 200. The small circular arc is positioned below the straight line segment, and the tail end of the small circular arc is tangent to the bottom wall of the smoke exhaust pipe 100 so as to be smoothly connected.

For ease of transportation, the first module 300 and the second module 400 in this embodiment may be placed in the smoke exhaust duct 100 at the same time. At this time, the end of the large arc of the first guide plate 310 is directly opposite to the end of the small arc of the second guide plate 410, i.e. the radius corresponding to the large arc plus the radius corresponding to the small arc is equal to the width of the outlet 210 (between the inner and outer casing walls) of the scroll casing 200.

In order to facilitate the installation and disassembly of the baffle, in this embodiment, the first support frame 320 includes a first vertical plate 322 and a first connecting rod 321 for connecting the first vertical plate 322 and the first baffle 310; the second supporting frame 420 includes a second vertical plate 422 and a second connecting rod 421 for connecting the second vertical plate 422 and the second flow guide plate 410. The first connecting rod 321 and the second connecting rod 421 are both horizontally disposed.

During smoke exhaust, the airflow may be discharged from the gap between the guide plate and the smoke exhaust pipe 100 to the direction of the vertical plate. For this reason, in this embodiment, the shapes of the first vertical plate 322 and the second vertical plate 422 are matched with the shape of the smoke outlet 130. When the first assembly 300 or the second assembly 400 is completely inserted into the smoke exhaust pipe 100, the first riser 322 or the second riser 422 will block the corresponding smoke exhaust, leaving only one smoke exhaust (opposite).

In order to further facilitate the installation and the disassembly of the guide plate, the inner wall of the smoke exhaust pipe 100 is provided with a guide rail 120 (see fig. 3 and 4), and the edge of the guide plate is provided with a rail groove 500 (see fig. 5) matched with the guide rail 120; the guide rail 120 extends from outside to inside along the smoke exhaust pipe. The guide rail 120 may be disposed on a top wall, a side wall, or a bottom wall of the smoke exhaust duct 100.

In this embodiment, in order to further reduce noise, the guide rails 120 are in a shape of a strip plate, and are disposed on the side wall of the smoke exhaust pipe 100 and perpendicular to the side wall of the smoke exhaust pipe 100, the guide rails 120 are multiple, and the guide rails 120 are parallel, so that when the flow guide assembly is disposed in one of the smoke exhaust ports 130, the parallel guide rails 120 located on one side of the other smoke exhaust port 130 can reduce the degree of separation of air flow flowing near the inner wall of the smoke exhaust pipe 100, thereby reducing noise. The air flow separation degree refers to that the air flows on the upper and lower sides of the guide rail 120 can flow in an orderly layered manner through the parallel guide rail 120, so that the air flow is prevented from flowing back and forth.

In addition, in order to conveniently draw the flow guide assembly out of the smoke outlet 130 or push the flow guide assembly into the smoke outlet 130, a handle 600 is disposed on each of the first vertical plate 322 and the second vertical plate 422 of the embodiment.

Example 2:

as shown in fig. 7 and 8, the present embodiment provides another smoke exhaust pipe structure applied to an integrated stove, in which a first guide plate 310 and a second guide plate 410 are applied to a volute 200 shown below in fig. 6, at an air outlet 210 of the volute 200, a casing wall located at an inner side and a casing wall located at an outer side are not perpendicular to a smoke exhaust pipe 100, that is, angle 3 and angle 4 are acute angles or obtuse angles.

In order to make the upper end of the flow guide plate smoothly connected to the air outlet 210 of the scroll casing 200, the lower end of the flow guide plate is tangent to the bottom wall of the smoke exhaust pipe 100. When the shape line of the first baffle 310 and the shape line of the second baffle 410 are curved with a larger radius, such as a circular arc with a larger radius, the horizontal width of the first baffle 310 plus the horizontal width of the second baffle 410 is much larger than the width of the outlet 210 (between the inner and outer walls) of the scroll 200. When the first module 300 and the second module 400 are received by using a conventional receiving method, the situation shown in fig. 7 may occur, that is, if the first baffle 310 and the second baffle 410 are completely received, cross interference may occur at a position a in fig. 7, and the receiving may not be achieved.

Therefore, the storage mode as shown in fig. 8 can be adopted, one of the guide plates is turned over by 180 degrees up and down and then put into the smoke exhaust pipe 100 for storage, and the guide plate can be staggered with the other guide plate in the smoke exhaust pipe 100 after being turned over, so that interference is avoided, and the space can be fully utilized. Thus, in this embodiment, when the smoke exhaust pipe 100 is provided with the plurality of parallel guide rails 120, the vertical symmetry is ensured, so that the guide rails 120 can be normally used for installation when one of the guide plates is turned over at will. Correspondingly, the position of the rail groove on the guide plate also needs to be adjusted according to the guide rail.
