Description

Technical Field

[0001] The invention discloses a heat dissipation and dehumidification system and a steaming and baking machine comprising the same. Background Art

[0002] The stove-steam oven combination machine generally adopts an integrated design with a stove placed on top and a steam oven placed on the bottom. The stove is equipped with a heat dissipation duct system to fully guarantee the stable operation of various precision electronic components. However, given the upper and lower layout characteristics of the stove and the steam oven, it directly affects the overall air circulation efficiency, especially the exhaust smoothness of the steam oven. Therefore, it is considered to open a ventilation hole at the front end of the stove, close to the end of the heat dissipation duct, and equip the bottom with a condensation water box support box and a condensation water box, and the pipe under the condensation water box is seamlessly connected to the exhaust pipe at the bottom of the steam oven, together to build a set of efficient dehumidification system to ensure the dryness and freshness of the internal environment of the stove-steam oven combination machine.

[0003] At present, the heat dissipation air duct adopts a single duct structure, which will cause most of the gas to flow along the lower panel of the air guide plate, resulting in upper and lower stratification. When reaching the condensate water box grille, part of the gas will directly impact the left inner wall of the condensate water box and form a backflow in the condensate water box, resulting in increased resistance in the exhaust pipe channel of the steam oven and reduced exhaust efficiency. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defect that the heat dissipation air duct adopts a single air duct structure in the prior art and will produce upper and lower stratification, and to provide a heat dissipation and dehumidification system and a steam-bake machine comprising the same.

[0005] The present invention solves the above technical problems through the following technical solutions:

[0006] The present invention discloses a heat dissipation and dehumidification system, which is applied to a steam-bake all-in-one machine, and comprises an air guide, a condensation box and a fan, wherein a main channel and a microchannel are provided in the air guide, an air inlet of the main channel and an air inlet of the microchannel are both connected to the fan, an air outlet of the main channel and an air outlet of the microchannel are both connected to the air inlet of the condensation box, the main channel and the microchannel are distributed in an axial direction, and the main channel is located above the microchannel;

[0007] Wherein, the cross-sectional area of ​​the main channel is greater than the cross-sectional area of ​​the microchannel.

[0008] In this solution, the cross-sectional area of ​​the microchannel is smaller than that of the main channel, which increases the speed of the gas entering the condensation box from the microchannel, so that the gas entering the condensation box from the microchannel can form an air curtain in the condensation box, thereby preventing the airflow in the channel from sinking and improving the orderliness and efficiency of the gas flow. In addition, with the above-mentioned structural form, the cross-sectional area of ​​the main channel is larger than the cross-sectional area of ​​the microchannel, thereby increasing the flow rate of the gas passing through the main channel, increasing the gas flow rate of the main channel, making the gas smoother and continuous, and thus effectively reducing the phenomenon of airflow separation.

[0009] Preferably, the cross-sectional area of ​​the main channel gradually decreases from the air inlet of the main channel to the air outlet of the main channel.

[0010] In this solution, the above-mentioned structural form is adopted so that the gas velocity gradually increases from the air inlet to the air outlet, making the gas distribution more uniform, thereby effectively reducing the phenomenon of gas diversion.

[0011] Preferably, the ratio of the cross-sectional area of ​​the main channel to the cross-sectional area of ​​the microchannel is A, wherein A is not less than 3 and not more than 4.

[0012] In this solution, the above-mentioned structural form is adopted to further reduce the phenomenon of air flow diversion.

[0013] Preferably, the heat dissipation and dehumidification system further comprises a grille, both ends of which are respectively connected to the inner wall surface of the air inlet of the condensation box, and the extension direction of the grille is not parallel to the horizontal direction.

[0014] In this solution, the extension direction of the grille is not parallel to the horizontal direction, which reduces the gas resistance when the gas flows through the grille, thereby increasing the gas flow rate and reducing the possibility of gas stratification. The above structure allows the gas entering the condensation box to be at a certain angle to the horizontal direction, preventing the gas from being perpendicular to the inner wall of the condensation box and directly hitting the inner wall of the condensation box, thereby reducing the momentum loss of the gas.

[0015] Preferably, the extension direction of the grille is a vertical direction.

[0016] In this solution, the above structure is adopted to further reduce the possibility of gas stratification. In addition, the extension direction of the grid is vertical, which can further reduce the momentum loss of the gas.

[0017] Preferably, the cross-section of the air inlet of the condensation box is stepped, and the first connection surface of the condensation box with the main channel is farther away from the center of the condensation box than the second connection surface of the condensation box with the microchannel.

[0018] In the present solution, the above-mentioned structural form is adopted so that the air inlet of the condensation box matches the shape of the main channel and the microchannel, thereby increasing the connection area between the condensation box and the main channel and the microchannel respectively, thereby improving the stability and reliability of the connection between the condensation box and the main channel and the microchannel.

[0019] Preferably, the angle between the extension direction of the first connecting surface and the axial direction of the main channel is not less than 30 degrees and not more than 90 degrees;

[0020] And / or, the angle between the extension direction of the second connecting surface and the axial direction of the microchannel is not less than 30 degrees and not more than 90 degrees.

[0021] In this solution, the above-mentioned structural form is adopted to prevent the collision and backflow when the air flow enters the air inlet of the condensation box, reduce the loss of momentum of the air flow, and improve the gas flow rate, so as to achieve the optimal relationship between the air flow guiding effect and momentum.

[0022] Preferably, a plurality of first exhaust holes and a plurality of second exhaust holes are provided on the upper surface of the condensation box, the plurality of first exhaust holes and the plurality of second exhaust holes are arranged at intervals on the upper surface of the condensation box, and the first exhaust holes are closer to the main channel than the second exhaust holes;

[0023] The axis direction of the main channel passes through the first exhaust hole, and the axis direction of the microchannel passes through the second exhaust hole.

[0024] In the present solution, the above-mentioned structural form is adopted, so that the airflow in the microchannel can be discharged from the second exhaust hole, and the gas in the main channel can be discharged from the first exhaust hole, thereby preventing the problem of gas accumulation in the condensation box and improving the gas flow rate on the upper surface of the condensation box.

[0025] Preferably, the slope of the upper surface of the main channel is smaller than the slope of the lower surface of the main channel;

[0026] And / or, the slope of the upper surface of the microchannel is greater than the slope of the lower surface of the microchannel.

[0027] In this solution, the above-mentioned structural form can prevent the gas from forming vortices in the guide member, improve the main channel and microchannel's ability to guide the airflow, and thus make the gas flow in the main channel and microchannel smoother and continuous, effectively reducing the phenomenon of gas separation.

[0028] Preferably, the slope of the upper surface of the main channel is not less than 5 and not less than 10;

[0029] And / or, the slope of the lower surface of the main channel is not less than 6 and not more than 12.

[0030] In the present solution, the above-mentioned structural form is adopted to ensure that the direction of change of the gas velocity is highly consistent with the direction of change of the slope of the guide member, thereby achieving a smooth transition and efficient utilization of the airflow, so that the gas can pass through the air inlet of the condensation box at a certain inclination angle and can be discharged from the first exhaust hole and the second exhaust hole more evenly, avoiding airflow obstruction.

[0031] Preferably, the condensation box comprises a condensation water box and a support box, the condensation water box is arranged inside the support box, and a diversion channel is formed between the condensation water box and the support box, and the diversion channel is connected to the air inlet of the condensation box.

[0032] In this solution, the above structure is adopted so that the gas entering from the air inlet of the condensation box carries a certain temperature, and the gas can exchange heat with the condensed water droplets in the condensation water box during the flow. This process not only accelerates the evaporation rate of the water droplets, but also effectively reduces the amount of water accumulated in the condensation water box, thereby reducing the volume requirement of the condensation water box.

[0033] Preferably, one end of the diversion channel away from the air inlet of the condensation box is connected to the second exhaust hole.

[0034] In this solution, the above-mentioned structural form is adopted to reduce the possibility of the airflow directly hitting the left side wall of the support box, thereby avoiding the backflow phenomenon caused by the impact and improving the smoothness of gas circulation.

[0035] The present invention also discloses a steam-bake machine, which comprises the heat dissipation and moisture removal system as described in any one of the above items.

[0036] In this solution, the above-mentioned structural form is adopted, and the cross-sectional area of ​​the microchannel is smaller than the cross-sectional area of ​​the main channel, which increases the speed of the gas entering the condensation box from the microchannel, so that the gas entering the condensation box from the microchannel can form an airflow curtain in the condensation box, thereby preventing the airflow in the channel from sinking, and improving the orderliness and efficiency of the gas flow. In addition, the above-mentioned structural form is adopted, and the cross-sectional area of ​​the main channel is larger than the cross-sectional area of ​​the microchannel, thereby increasing the flow rate of the gas passing through the main channel, increasing the gas flow rate of the main channel, making the gas smoother and continuous, and thus effectively reducing the phenomenon of airflow separation.

[0037] The positive and progressive effects of the present invention are:

[0038] The cross-sectional area of ​​the microchannel is smaller than that of the main channel, which increases the speed of the gas entering the condensation box from the microchannel, so that the gas entering the condensation box from the microchannel can form an air curtain in the condensation box, thereby preventing the airflow in the channel from sinking and improving the orderliness and efficiency of the gas flow. In addition, with the above-mentioned structural form, the cross-sectional area of ​​the main channel is larger than the cross-sectional area of ​​the microchannel, thereby increasing the flow rate of the gas passing through the main channel, increasing the gas flow rate of the main channel, making the gas smoother and continuous, and thus effectively reducing the phenomenon of airflow separation.

[0061] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0062] like Figures 1 to 6 As shown, this embodiment provides a heat dissipation and dehumidification system 100, which is applied to a steam-bake combination machine. The heat dissipation and dehumidification system 100 includes an air guide 1, a condensation box 2 and a fan 3. A main channel 11 and a microchannel 12 are provided in the air guide 1. The air inlet of the main channel 11 and the air inlet of the microchannel 12 are both connected to the fan 3, and the air outlet of the main channel 11 and the air outlet of the microchannel 12 are both connected to the air inlet of the condensation box 2. The main channel 11 and the microchannel 12 are distributed in the axial direction, and the main channel 11 is located above the microchannel 12; wherein the cross-sectional area of ​​the main channel 11 is greater than the cross-sectional area of ​​the microchannel 12. Specifically, the cross-sectional area of ​​the microchannel 12 is smaller than the cross-sectional area of ​​the main channel 11, which increases the speed of the gas entering the condensation box 2 from the microchannel 12, so that the gas entering the condensation box 2 from the microchannel 12 can form an air curtain in the condensation box 2, thereby preventing the air flow in the channel from sinking, and improving the orderliness and efficiency of the gas flow. In addition, by adopting the above-mentioned structural form, the cross-sectional area of ​​the main channel 11 is larger than the cross-sectional area of ​​the microchannel 12, thereby increasing the flow rate of gas passing through the main channel 11, increasing the gas flow rate of the main channel 11, making the gas flow smoother and continuous, and thus effectively reducing the phenomenon of gas flow separation.

[0063] It should be specifically explained that this embodiment is schematically expressed by taking the number of main channels 11 and microchannels 12 as one. In other embodiments, the number of main channels 11 and microchannels 12 can be adjusted according to actual needs and is not limited here.

[0064] In this embodiment, the ratio of the cross-sectional area of ​​the main channel 11 to the cross-sectional area of ​​the microchannel 12 is A, wherein A is not less than 3 and not greater than 4, thereby further reducing the phenomenon of airflow diversion. Specifically, with the above-mentioned structural form, the airflow in the main channel 11 accounts for 75%-80% of the total flow, and the airflow in the microchannel 12 accounts for only 20%-25% of the total flow. Since the lengths of the main channel 11 and the microchannel 12 are the same, the ratio of the air inlet of the main channel 11 to the air inlet of the microchannel 12 is B, and B is not less than 3 and not greater than 4, and the ratio of the air outlet of the main channel 11 to the air outlet of the microchannel 12 is C, and C is not less than 3 and not greater than 4.

[0065] like Figure 5 As shown, the cross-sectional area of ​​the main channel 11 gradually decreases from the air inlet of the main channel 11 to the air outlet of the main channel 11. With the above structure, the gas velocity gradually increases from the air inlet to the air outlet, making the gas distribution more uniform, thereby effectively reducing the phenomenon of gas diversion.

[0066] like Figure 6 As shown, the heat dissipation and dehumidification system 100 also includes a grille 4, the two ends of which are respectively connected to the inner wall surface of the air inlet of the condensation box 2, and the extension direction of the grille 4 is not parallel to the horizontal direction. Specifically, the extension direction of the grille 4 is not parallel to the horizontal direction, which reduces the gas resistance when the gas flows through the grille 4, thereby increasing the gas flow rate, and further reducing the possibility of airflow stratification. With the above-mentioned structural form, the gas entering the condensation box 2 can be at a certain angle with the horizontal direction, preventing the gas from being perpendicular to the inner wall of the condensation box 2 and directly hitting the inner wall surface of the condensation box 2, thereby reducing the momentum loss of the gas.

[0067] In this embodiment, the grid 4 extends in a vertical direction, which further reduces the possibility of gas stratification.

[0068] In addition, the lower end of the grid 4 does not exceed the lower surface of the microchannel 12 , thereby preventing other gases outside the microchannel 12 from entering the condensation box 2 .

[0069] like Figures 4 to 6 As shown, the cross section of the air inlet of the condensation box 2 is stepped, and the first connection surface 21 of the condensation box 2 with the main channel 11 is farther away from the center of the condensation box 2 than the second connection surface 22 of the condensation box 2 with the microchannel 12. With the above structure, the air inlet of the condensation box 2 matches the shape of the main channel 11 and the microchannel 12, and the connection area between the condensation box 2 and the main channel 11 and the microchannel 12 is increased, thereby improving the stability and reliability of the connection between the condensation box 2 and the main channel 11 and the microchannel 12.

[0070] There may be the following embodiments for the first connecting surface 21 and the second connecting surface 22; in a first embodiment, the angle between the extension direction of the first connecting surface 21 and the axial direction of the main channel 11 is not less than 30 degrees and not greater than 90 degrees; in a second embodiment, the angle between the extension direction of the second connecting surface 22 and the axial direction of the microchannel 12 is not less than 30 degrees and not greater than 90 degrees; in a third embodiment, the angle between the extension direction of the first connecting surface 21 and the axial direction of the main channel 11 is not less than 30 degrees and not greater than 90 degrees, and the angle between the extension direction of the second connecting surface 22 and the axial direction of the microchannel 12 is not less than 30 degrees and not greater than 90 degrees.

[0071] Preferably, in this embodiment, the angle between the extension direction of the first connection surface 21 and the axial direction of the main channel 11 is not less than 30 degrees and not more than 90 degrees, and the angle between the extension direction of the second connection surface 22 and the axial direction of the microchannel 12 is not less than 30 degrees and not more than 90 degrees. The above-mentioned structural form can prevent the airflow from colliding and backflowing when entering the air inlet of the condensation box 2, reduce the loss of momentum of the airflow, and improve the flow rate of the gas, so as to achieve the optimal relationship between the airflow guiding effect and the momentum.

[0072] like Figure 4 As shown, the upper surface of the condensation box 2 is provided with a plurality of first exhaust holes 23 and a plurality of second exhaust holes 24, which are arranged at intervals on the upper surface of the condensation box 2, and the first exhaust holes 23 are closer to the main channel 11 than the second exhaust holes 24; wherein the axis direction of the main channel 11 passes through the first exhaust holes 23, and the axis direction of the microchannel 12 passes through the second exhaust holes 24. With the above-mentioned structural form, the airflow of the microchannel 12 can be discharged from the second exhaust holes 24, and the gas in the main channel 11 can be discharged from the first exhaust holes 23, thereby preventing the problem of gas accumulation in the condensation box 2 and improving the gas flow rate on the upper surface of the condensation box 2.

[0073] For the main channel 11 and the microchannel 12, there can be the following implementation modes: in the first implementation mode, the slope of the upper surface of the main channel 11 is smaller than the slope of the lower surface of the main channel 11; in the second implementation mode, the slope of the upper surface of the microchannel 12 is larger than the slope of the lower surface of the microchannel 12; in the third implementation mode, the slope of the upper surface of the main channel 11 is smaller than the slope of the lower surface of the main channel 11, and the slope of the upper surface of the microchannel 12 is larger than the slope of the lower surface of the microchannel 12.

[0074] Preferably, in this embodiment, the slope of the upper surface of the main channel 11 is smaller than the slope of the lower surface of the main channel 11, and the slope of the upper surface of the microchannel 12 is larger than the slope of the lower surface of the microchannel 12. The above-mentioned structural form can prevent the gas from forming vortices in the flow guide, improve the guiding ability of the main channel 11 and the microchannel 12 to the airflow, and thus make the flow of the gas in the main channel 11 and the microchannel 12 smoother and more continuous, effectively reducing the phenomenon of gas separation.

[0075] In this embodiment, the slope of the upper surface of the main channel 11 is not less than 5 and not less than 10; the slope of the lower surface of the main channel 11 is not less than 6 and not more than 12. The above structure ensures that the direction of change of the gas velocity is highly consistent with the direction of change of the slope of the guide member, thereby achieving smooth transition and efficient use of the airflow, so that the gas can pass through the air inlet of the condensation box 2 at a certain inclination angle, and can be discharged from the first exhaust hole 23 and the second exhaust hole 24 more evenly, avoiding airflow obstruction.

[0076] like Figure 3 As shown, the condensation box 2 includes a condensation water box 25 and a support box 26. The condensation water box 25 is arranged inside the support box 26, and a shunt channel 27 is formed between the condensation water box 25 and the support box 26. The shunt channel 27 is connected to the air inlet of the condensation box 2. The above structure allows the gas entering from the air inlet of the condensation box 2 to carry a certain temperature. At this time, the gas can exchange heat with the water droplets condensed in the condensation water box 25 during the flow process. This process not only accelerates the evaporation rate of the water droplets, but also effectively reduces the amount of water accumulated in the condensation water box 25, thereby reducing the volume requirement of the condensation water box 25.

[0077] In this embodiment, the diversion channel 27 is connected to the air outlet of the microchannel 12, so that after the high-speed airflow passes through the microchannel 12 and the grille 4, a strong airflow curtain is formed in the diversion channel 27, thereby effectively preventing the airflow in the main channel 11 from sinking and improving the orderliness and efficiency of the gas flow.

[0078] One end of the shunt channel 27 away from the air inlet of the condensation box 2 is connected to the second exhaust hole 24. The above structure can reduce the possibility of the airflow directly hitting the left side wall of the support box 26, thereby avoiding the backflow phenomenon caused by the impact and improving the smoothness of gas circulation.

[0079] In specific use, the air inlet of the condensation box 2 is opened on the first connection surface 21 and the second connection surface 22 of the support box 26 facing the support member, so as to form a circulation channel 28 between the first surface and the condensation water box 25. At this time, the shunt channel 27 is only an auxiliary microchannel 12 compared with the circulation channel 28, that is, the gas flow in the circulation channel 28 needs to account for 75%-85% of the total flow, and the gas flow in the shunt channel 27 only accounts for 15%-25% of the total flow. The gap d of the shunt channel 27 is controlled within a certain range, that is, 5mm≤d ≤13mm. In addition, the design of the guide ribs of the shunt channel 27 should ensure that the shunt channel 27 adopts a tapered structure from the air inlet of the condensation box 2 to the air outlet of the condensation box 2, that is, the flow area of ​​the gas on the air flow path decreases in direct proportion, so as to control the air flow to have a larger speed in the shunt channel 27 to control the backflow of the gas in the support box 26.

[0080] In addition, when the depth w of the condensed water box 25 does not exceed the lowest point of the grille 4 holes in the microchannel 12, the above structure is adopted, so that the airflow has a relatively high speed when passing through the grille 4. After the gas quickly passes through the grille 4 holes at a certain inclination angle α, a negative pressure area will be formed above the condensed water box 25 and near the grille 4 opening, so as to avoid the phenomenon of gas sinking at the grille 4 in the airflow of the microchannel 12 and the main channel 11, and at the same time, it can also play a certain role in draining the gas in the exhaust pipe.

[0081] This embodiment also discloses a steam-bake machine, which includes a heat dissipation and dehumidification system 100. With the above-mentioned structural form, the cross-sectional area of ​​the microchannel 12 is smaller than the cross-sectional area of ​​the main channel 11, which increases the speed of the gas entering the condensation box 2 from the microchannel 12, so that the gas entering the condensation box 2 from the microchannel 12 can form an air curtain in the condensation box 2, thereby preventing the airflow in the channel from sinking, and improving the orderliness and efficiency of the gas flow. In addition, with the above-mentioned structural form, the cross-sectional area of ​​the main channel 11 is larger than the cross-sectional area of ​​the microchannel 12, thereby increasing the flow rate of the gas passing through the main channel 11, increasing the gas flow rate of the main channel 11, making the gas smoother and more continuous, and thus effectively reducing the phenomenon of airflow separation.
