Examples

Referring to fig. 1 to 5, an embodiment of the present application provides a heating exhaust duct 100 for a motor vehicle kitchen, including:

the back plate 10, the back plate 10 has multiple aspiration inlets 11;

the air duct structure 20, the air duct structure 20 includes a first air duct 21 and a second air duct 22, the first air duct 21 is connected to the air suction opening 11, the first air duct 21 is communicated with the second air duct 22, and the second air duct 22 is used for being connected with a fan;

a baffle 30;

the first air duct 21 close to the air outlet of the second air duct 22 is a near-end air duct 211, the first air duct 21 far from the air outlet of the second air duct 22 is a far-end air duct 212, and the baffle 30 is disposed at a joint of the near-end air duct 211 and the second air duct 22, so that the ventable cross-sectional area of the near-end air duct 211 is equal to or close to the ventable cross-sectional area of the far-end air duct 212.

In a simple manner, by arranging the baffle 30 on the near-end air duct 211, the ventilation rate of the near-end air duct 211 in unit time can be reduced, so that the ventilation rate of the far-end air duct 212 is basically consistent with that of the near-end air duct 211, the flow control of the suction ports 11 is realized, the flow of each suction port 11 is ensured to be uniform, and the local heat accumulation is avoided.

Referring to fig. 1 and fig. 3 to 5, the number of the suction openings 11 is four, the number of the first air ducts 21 is four, the number of the second air ducts 22 is one, and the first air ducts 21 and the second air ducts 22 are in a dry shape. It will be understood that, in the case of a motor vehicle with a larger space in the galley compartment, it is also conceivable to add the air suction opening 11 and to provide it with a corresponding first air duct 21, which is then connected to the main exhaust air duct via the second air duct 22. Similarly, when the air suction opening 11 is reduced, the first air duct 21 may also be adjusted correspondingly.

In addition, it should be noted that when the number of the first air ducts 21 is greater or less, or the arrangement position of the first air ducts 21 is changed, the far end and the near end can still be divided according to the flowing direction of the air flow, the baffle 30 can be arranged from far to near, and the size of the baffle 30 can be adjusted accordingly, so that the cross-sectional areas of the ventable openings of the first air ducts 21 are equal or close to each other when the first air ducts 21 are connected to the second air ducts 22, and the flow rate of the air suction openings 11 is uniform.

Of course, when other numbers of second air ducts 22 are provided, a suitable baffle 30 may be provided accordingly, for example, two second air ducts 22 are provided, two first air ducts 21 may be connected to one second air duct 22, and the other two first air ducts 21 are connected to another second air duct 22, and by providing the baffle 30 on the near-end air duct 211, the ventilation cross-sectional area of the first air duct 21 is changed, so that the flow rate of each air suction opening 11 is still uniform, and the local heat accumulation is avoided. The design of the other number of the second air ducts 22 and the first air ducts 21 can be adjusted accordingly, so that the number of the air suction openings 11 can meet the requirements of the kitchen compartment.

Referring to fig. 4, the exhaust heating duct 100 further includes a slope portion 40, and the slope portion 40 is disposed at a joint of the first duct 21 and the second duct 22.

Further, the slope of the slope portion 40 is 45 °.

In this embodiment, the ramp portion 40 is divided into an upper portion 41 and a lower portion 42 in the vertical direction, and the upper portion 41 of the proximal air duct 211 is engaged with the baffle 30. The baffle 30 of the near-end air duct 211 is integrated with the upper portion 41, so that the area of the ventilation cross section of the near-end air duct 211 can be limited by the baffle 30, the problem that more air flow impacts the baffle 30 to cause air flow disorder and affect stable air inlet of the air suction opening 11 can be avoided, and the problem that the air flow of each first air duct 21 is stably converged in the second air duct 22 can be avoided.

It should be noted that the angles of the slope portions 40 of the upper portion 41 and the lower portion 42 may be the same or different, in the present embodiment, the slope of the slope portion 40 referred to above is 45 ° mainly referred to as the upper portion 41, and the slope of the lower portion 42 is 42 ° in the present embodiment. Of course, the angle is only an example, and other angles, such as 40 °, 50 °, etc., can be designed by those skilled in the art, as long as it is beneficial to guide the gas flow and avoid the gas flow from turning at right angles to generate a large amount of vortex.

In addition, the size and angle of the respective ramp portions 40 may also be different for the proximal air duct 211 and the distal air duct 212, and the inclined guiding structure where the first air duct 21 joins the second air duct 22 is generally referred to as the ramp portion 40 in this application, and does not limit that the inclined guiding structure at each position must be completely consistent. Certainly, through the experiment, the air current in each first wind channel 21 can be made more stable by the "do" style of calligraphy structure of this application, has abandoned current spatial layout completely. The suction force at the 4 suction openings 11 is balanced, and under the guidance of the slope portion 40, when the airflow is collected to the second air duct 22, a large vortex cannot be generated, so that the airflow is prevented from flowing smoothly.

In addition, for the far-end air duct 212, the upper parts 41 of the two air ducts are connected, so that the air flow is guided and blocked to some extent, and when the power of the fan is high, the problem that the air flows of the two far-end air ducts 212 impact each other too much to generate high noise when being converged can be avoided, and the stability of the whole air flow is influenced.

With reference to fig. 1, the exhaust duct 100 for heating the motor vehicle kitchen further includes a mesh enclosure 50, and the mesh enclosure 50 is disposed at the air inlet 11.

With continued reference to FIG. 3, the volume of the portion H of the second air duct 22 near the proximal air duct 211 is greater than the volume of the portion S near the distal air duct 212. Since the section H is an area where the airflows of the four first air ducts 21 finally meet, the area can be increased in volume to avoid the crowding of the airflow, thereby reducing the vortex or turbulence phenomenon caused by the crowding of the airflow and promoting the smooth discharge of the airflow.

In the present embodiment, the exhaust heating duct 100 further includes a turning duct 60, and the turning duct 60 is used for communicating the second duct 22 with the fan according to the position of the fan.

Wherein, the turning duct 60 is fixed with the back plate 10 by a clamp 70.

Based on the above-mentioned motor car kitchen heating exhaust air duct 100, the embodiment of the application provides a motor car kitchen, including automobile body, main exhaust gas passageway and motor car kitchen heating exhaust air duct 100, and the main exhaust gas passageway sets up in the automobile body, and motor car kitchen heating exhaust air duct 100's second wind channel 22 passes through fan and main exhaust gas passageway intercommunication.

Wherein, the vehicle body and the main exhaust gas channel can refer to the prior art, and are not described in detail here.

Because the space in the vehicle body is limited, for some vehicle types which are not suitable for directly connecting the second air duct 22 with the fan, the turning air duct 60 can be additionally arranged to complete the connection between the second air duct 22 and the fan, so that the heated waste gas can be normally discharged into the main waste gas channel.

The principle of the embodiment is as follows:

there are four microwave ovens in the car body, and the back of the microwave oven is the corresponding heating waste discharge channel, which is the air suction opening 11 in this embodiment. In the prior art, the distance between the back of the microwave oven and the inner wall of the carriage is very limited, and the conventional layout mode of the heating waste discharge channel is only provided with a wind port simply and leads the water to the main waste discharge channel by a fan. The suction of each wind gap can be caused to be very different, in practice, local heat accumulation can be easily generated, the normal use of adjacent equipment can be influenced, and the microwave oven can also be influenced due to poor heat dissipation effect.

As shown in the following table, the flow rate and volume flow of the four tuyeres of the existing waste discharge channel are very different, and the problem of heat accumulation is easily caused. Wherein, the wind speed and the flow of the tuyere close to the fan are both larger.

Tuyere	Speed [ m/s ]]	Volume flow rate [ m ^3/s]
			1	1.560	0.041
2	1.737	0.046
			3	0.271	0.010
4	0.183	0.007

Therefore, the baffle 30 is designed in the heating exhaust duct 100 for the motor vehicle kitchen of the embodiment, so that the airflow rate of each air suction opening 11 is uniform. And the slope part 40 is designed, so that the outline of the air channel can be matched with the path of normal flow of the air flow, and the air flow is prevented from turning at right angles to generate larger turbulence and noise. The structural design of doing the style of calligraphy can enough satisfy the installation in narrow and small space, can avoid again taking too much space for vacant space can supply other devices to install and use, can also make each first wind channel 21 assemble the second wind channel 22 of central authorities, and the gas stroke is close, more does benefit to stably to converge, noise reduction. The back plate 10 can refer to the existing back plate 10, the air duct structural member 20 can be made of glass fiber reinforced plastics, the production difficulty is reduced, the final product is guaranteed, the cost is lower than that of sheet metal manufacturing, and the air duct structural member has actual popularization value.

Through experiments, the data shown in the following table can be obtained:

air suction inlet	Speed [ m/s ]]	Volume flow rate [ m ^3/s]
			1	1.051	0.024
2	1.057	0.024
			3	1.003	0.022
4	1.005	0.022

As can be seen from the data, the air speed and the flow of each air suction opening 11 are uniform, and the existing problems are successfully solved. The number of the air suction opening is 1 at the lower right, 2 at the lower left, 3 at the upper right and 4 at the upper left in the view angle of fig. 5.
