Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and particularly to a steam discharge control method for an integrated stove and an integrated stove. Background Art

[0002] The integration of various steam and roast cooking devices is the development direction of future cooking equipment, which has the advantages of small kitchen occupancy space, etc. However, in the existing technology, the integrated stove usually arranges the steam and roast cooking device below the cooking range, and at the same time arranges the steam discharge port on the cooking range panel. However, such an arrangement will bring certain defects. For example, after the steam is discharged from the discharge port of the cooking range panel, it will disperse everywhere above the cooking range panel. The dispersed steam hits the stove top bracket and the range hood components. The relatively high-temperature steam condenses into small water droplets on the room-temperature components. When those small water droplets accumulate to a certain extent, they will flow down along the walls of the components and finally flow onto the cooking range panel and the kitchen countertop, resulting in the soiling of the cooking range panel and the kitchen countertop. Summary of the Invention

[0003] The purpose of the present invention is to provide a steam discharge control method for an integrated stove. The steam discharge control method for the integrated stove can adjust the wind power level of the exhaust fan according to different range hood heights and steam sizes, so that the steam of the steam and roast cooking device directly enters the smoke inlet from the exhaust port, avoiding the soiling of the cooking range panel and the kitchen countertop by the small water droplets condensed from the steam.

[0004] To achieve the purpose of the present invention, the present invention adopts the following technical solutions:

The height detection component is used to detect the distance value L between the exhaust port and the smoke inlet. The controller is respectively in communication connection with the height detection component and the exhaust fan. The steam discharge control method for the integrated stove includes: setting several different distance levels, steam levels, and fan levels in the controller, and associating the fan levels with the distance levels and the steam levels; after the controller receives the distance value L between the smoke inlet and the exhaust port, judging the distance level of the distance value L; the controller obtains the steam discharge amount H in the exhaust pipe to judge which steam level the steam discharge amount H belongs to; the controller starts the exhaust fan and adjusts it to the corresponding fan level, so that the steam of the steam and roast cooking device is directly blown into the smoke inlet from the exhaust port under the combined action of the exhaust fan and the range hood.

[0010] According to an embodiment of the present invention, when the range hood includes at least two fan speed gears, the integrated cooking stove further includes a rotation speed detector, which is arranged at the position of the range hood's fan to detect the rotation speed of the range hood's fan. The rotation speed detector is also communicatively connected to the controller. The controller adjusts the rotation speed gear of the exhaust fan to be adapted to that of the range hood's fan, so that all the steam at the exhaust port enters the smoke inlet under the combined driving force of the exhaust fan and the range hood's fan.

[0011] According to an embodiment of the present invention, the integrated cooking stove further includes a steam detector, which is communicatively connected to the controller to obtain the remaining steam amount H' in the exhaust pipe through the steam detector. The integrated cooking stove steam emission control method further includes: setting a preset steam amount H0 for closing the exhaust fan in the controller; the steam detector detecting the remaining steam amount H' in the exhaust pipe and transmitting it to the controller, and the controller comparing H' with H0; when H'≤H0, the controller closes the exhaust fan.

[0012] According to another aspect of the present invention, there is provided an integrated cooking stove, which is controlled by the aforementioned integrated cooking stove steam emission control method. The integrated cooking stove further includes a heat dissipation channel and a heat dissipation fan. The air inlet of the heat dissipation channel is arranged between the cooking appliance and the door of the steam cooking and roasting device. The exhaust fan is arranged at the connection between the heat dissipation channel and the exhaust pipe to draw the air in the heat dissipation channel into the exhaust pipe.

[0013] According to an embodiment of the present invention, the exhaust pipe includes an exhaust cover and an exhaust housing. The exhaust cover covers the exhaust housing to enclose an exhaust cavity with an air inlet. The exhaust fan is arranged at the air inlet. The exhaust cover is provided with a pipeline outlet communicating with the exhaust cavity, and the pipeline outlet communicates with the exhaust port. The exhaust housing is provided with a pipeline inlet communicating with the exhaust cavity, and the pipeline inlet communicates with the inner cavity of the steam cooking and roasting device.

[0014] According to an embodiment of the present invention, the pipeline outlet and the pipeline inlet are oppositely arranged, and the cross-sectional area of one side of the exhaust cavity close to the air inlet is larger than that of the side of the exhaust cavity close to the pipeline outlet, so as to form a negative pressure at the pipeline outlet to accelerate the flow rate of steam from the pipeline inlet to the pipeline outlet.

[0015] According to an embodiment of the present invention, the side wall of the exhaust housing is provided with a buckle extending outwards, and the side wall of the exhaust cover is provided with a clamping hole.

[0017] According to an embodiment of the present invention, a slope extending obliquely from the air inlet to the pipeline outlet is provided on the exhaust housing, and the inclination angle of the slope is 20° to 80°, so that the wind generated by the exhaust fan can form a power completely directed towards the pipeline outlet.

[0018] According to an embodiment of the present invention, a water retaining rib protruding inwards is provided on the exhaust cover and / or the exhaust housing to prevent the condensed water from being discharged from the air inlet.

[0020] The integrated stove steam emission control method of the present invention can detect the distance value from the smoke inlet to the exhaust outlet through a height detection member, and obtain the steam emission amount of the steam cooking device through the cooking program of the steam cooking device. When the distance value is small and the steam emission amount is large, a blower fan gear with a lower speed can be set. When the distance value is large and the steam emission amount is large, a blower fan gear with a higher speed is required. Under the combined action of the exhaust fan and the smoke machine fan of the range hood, the steam of the steam cooking device directly enters the smoke inlet after being discharged from the exhaust outlet, avoiding high-temperature steam from condensing into small water droplets on the components at normal temperature and dripping onto the stove top and the kitchen countertop.

[0033] An embodiment of the present invention provides an integrated stove steam emission control method. The integrated stove includes an oil fume machine 1, a cooking appliance 2, a steaming and baking cooking device 3, a controller, and a height detector. The steaming and baking cooking device 3 includes an exhaust pipe 31 and an exhaust fan 32. The exhaust port 311 of the exhaust pipe 31 faces the smoke inlet 11 of the oil fume machine 1. The exhaust fan 32 is used to drive the steam in the exhaust pipe 31 to accelerate emission. The height detector is used to detect the distance between the exhaust port 311 and the smoke inlet 11. The controller is communicatively connected to the height detector and the exhaust fan 32 respectively. The integrated stove steam emission control method includes: setting a number of different distance gears, steam gears, and fan gears in the controller, and associating the fan gears with the distance gears and the steam gears; after the controller receives the distance value L between the smoke inlet 11 and the exhaust port 311, determining the distance gear of the distance value L; the controller obtaining the steam emission amount H in the exhaust pipe 31 to determine which steam gear the steam emission amount H belongs to; the controller starting the exhaust fan 32 and adjusting it to the corresponding fan gear, so that the steam of the steaming and baking cooking device 3 is directly blown into the smoke inlet 11 from the exhaust port 311 under the combined action of the exhaust fan 32 and the oil fume machine 1.

[0034] As Figure 1 and Figure 2 shown, the exhaust port 311 is arranged on the cooking appliance panel of the cooking appliance 2, preferably at a position between two burners on the cooking appliance panel. The smoke inlet 11 of the oil fume machine 1 is arranged above the exhaust port 311 and is directly opposite to the exhaust port 311. The height detector can be a distance measuring sensor. The height detector is arranged at the position of the exhaust port 311. The distance measuring sensor includes a transmitting probe and a receiving probe. Laser, infrared or ultrasonic waves are emitted from the transmitting probe towards the smoke exhaust port. Part of the scattered light after being reflected by the outer periphery of the smoke exhaust port returns to the receiving probe. By recording and processing the time experienced by the laser, infrared or ultrasonic waves from being emitted to being received, the distance from the smoke exhaust port to the exhaust port 311 can be measured. Of course, the height detector can also be arranged at the smoke inlet 11 and emit laser, infrared or ultrasonic waves towards the cooking appliance panel.

[0035] Different distance gears are set in the controller for different distances, different steam gears are set for different steam emission amounts, and different fan gears are set for different rotational speeds of the fan. The steam cooking device 3 also considers setting different steam gears according to different ingredients during operation. For example, when steaming fish, high-fire cooking is required, so the steam gear is the high-fire gear; when steaming eggs, low-fire cooking is required, so the steam gear is the low-fire gear. When the steam cooking device 3 is in the high-fire gear, the steam emission amount is at a relatively large steam gear, and the flow rate of the steam at the exhaust port 311 is also relatively fast. Therefore, at the same smoke machine fan gear of the range hood 1, the exhaust fan 32 only needs a relatively small fan gear to work together with the smoke machine fan to directly introduce the steam into the smoke inlet 11. When the steam cooking device 3 is in the low-fire gear, the steam emission amount is at a relatively small steam gear, and the flow rate of the steam at the exhaust port 311 is slow. Therefore, at the same smoke machine fan gear of the range hood 1, the exhaust fan 32 needs a relatively large fan gear to work together with the smoke machine fan to make the steam enter the smoke inlet 11.

[0036] In a preferred embodiment of the present invention, several distance gears include a first distance gear, a second distance gear, and a third distance gear. The first distance gear is less than 20 cm, the second distance gear is 20 cm to 40 cm, and the third distance gear is greater than 40 cm. The steam gears include a first steam gear, a second steam gear, and a third steam gear. The steam emission amount H is obtained through the cooking program of the steam cooking device 3. The first steam gear is a water consumption of 600 ml to 750 ml per hour, the second steam gear is a water consumption of 800 ml to 950 ml per hour, and the third steam gear is a water consumption of 1100 ml to 1300 ml per hour.

[0037] Among them, the range hood 1 is arranged above the cooking stove 2 and is a split structure with the cooking stove 2. The user can set the relative position of the range hood 1 and the cooking stove 2 according to the actual structure of the kitchen, as long as the smoke inlet 11 and the exhaust port 311 are correspondingly arranged. Preferably, the density of the steam is less than the density of the indoor air, so the flow direction of the steam is always upward. The smoke inlet 11 is arranged directly above the exhaust port 311, which can reduce the power required by the exhaust fan 32, thereby saving energy. According to the actual structure of the kitchen, three distance gears between the smoke inlet 11 and the exhaust port 311 are set in the controller. When the distance measuring sensor detects that the distance value L between the smoke inlet 11 and the exhaust port 311 is less than 20 cm, the controller determines that the distance value L is in the first distance gear. Similarly, when the distance measuring sensor detects that the distance value L between the smoke inlet 11 and the exhaust port 311 is between 20 cm and 30 cm, the controller determines that the distance value L is in the second distance gear. When the distance measuring sensor detects that the distance value L between the smoke inlet 11 and the exhaust port 311 is greater than 40 cm, the controller determines that the distance value L is in the third distance gear.

[0038] The cooking program of the steam cooking device 3 sets the first steam gear to consume 600 ml to 750 ml of water per hour, the second steam gear to consume 800 ml to 950 ml of water per hour, and the third steam gear to consume 1100 ml to 1300 ml of water per hour. When the cooking program set by the user, such as the steamed fish program, requires cooking in the third steam gear, the controller can directly determine that the steam emission H is in the third steam gear through the cooking program. When the cooking program set by the user, such as the steamed egg program, requires cooking in the first steam gear, the controller can directly determine that the steam emission H is in the first steam gear through the cooking program. Combining the distance gear and the steam gear, the controller can adjust the exhaust fan 32 to the corresponding fan gear, thereby reducing energy consumption when there is no need to use the maximum fan gear.

[0039] In a preferred embodiment of the present invention, the fan gears include a first fan gear, a second fan gear, and a third fan gear. The air volume of the first fan gear is 10 m 3 / min to 12 m 3 / min, the air volume of the second fan gear is 15 m 3 / min to 18 m 3 / min, and the air volume of the third fan gear is 20 m 3 / min to 23 m 3 / min.

[0040] Among them, the fan gears of the exhaust fan 32 in the controller are divided into three gears from small to large. The air volume of the first fan gear is 10 m 3 / min to 12 m 3 / min, which is a low wind speed gear. The air volume of the second fan gear is 15 m 3 / min to 18 m 3 / min, which is a medium wind speed gear. The air volume of the third fan gear is 20 m 3 / min to 23 m 3 / min, which is a high wind speed gear, corresponding to different gears with the steam emission H increasing from small to large and the distance value L increasing from small to large, and is reasonably set according to the actual situation to reduce energy waste.

[0041] In a preferred embodiment of the present invention, when the distance value L is in the first distance gear or the second distance gear and the steam emission amount H is in the first steam gear, the controller adjusts the exhaust fan 32 to the first fan gear; when the distance value L is in the first distance gear and the steam emission amount H is in the second steam gear or the third steam gear, or when the distance value L is in the second distance gear and the steam emission amount H is in the second steam gear, or when the distance value L is in the third distance gear and the steam emission amount H is in the first steam gear, the controller adjusts the exhaust fan 32 to the second fan gear; when the distance value L is in the second distance gear and the steam emission amount H is in the third steam gear, or when the distance value L is in the third distance gear and the steam emission amount H is in the second steam gear or the third steam gear, the controller adjusts the exhaust fan 32 to the third fan gear.

[0042] Among them, when the distance value L is in the first distance gear or the second distance gear and the steam emission amount H is in the first steam gear, both the distance value L and the steam emission amount H are relatively small. The controller can then adjust the gear of the exhaust fan 32 to operate in the first fan gear with an air volume of 10 m 3 / min to 12 m 3 / min, which is sufficient to allow the steam to be discharged from the exhaust port 311 and then enter the smoke inlet 11.

[0043] When the distance value L is in the first distance gear and the steam emission amount H is in the second steam gear or the third steam gear, the controller adjusts the exhaust fan 32 to the second fan gear; when the distance value L is in the second distance gear and the steam emission amount H is in the second steam gear, the controller adjusts the exhaust fan 32 to the second fan gear; when the distance value L is in the third distance gear and the steam emission amount H is in the first steam gear, the controller adjusts the exhaust fan 32 to the second fan gear, which is sufficient to allow the steam to be discharged from the exhaust port 311 and then enter the smoke inlet 11.

[0044] When the distance value L is in the second distance gear and the steam emission amount H is in the third steam gear, the controller adjusts the exhaust fan 32 to the third fan gear; when the distance value L is in the third distance gear and the steam emission amount H is in the second steam gear or the third steam gear, the controller adjusts the exhaust fan 32 to the third fan gear, which is sufficient to allow the steam to be discharged from the exhaust port 311 and then enter the smoke inlet 11.

[0045] In a preferred embodiment of the present invention, when the range hood 1 includes at least two range hood gears, the integrated stove further includes a rotation speed detection component. The rotation speed detection component is arranged at the position of the range hood fan of the range hood 1 for detecting the rotation speed of the range hood fan. The rotation speed detection component is also communicatively connected to the controller. Among them, the controller adjusts the rotation speed gear of the exhaust fan 32 to be adapted to the range hood fan so that the steam at the exhaust port 311 can enter the smoke inlet 11 under the combined driving force of the exhaust fan 32 and the range hood fan.

[0046] When the range hood 1 is provided with at least two blower speeds, the blower speed of the blower of the range hood 1 can also be directly obtained through the control program of the range hood 1 in the controller. Thus, the blower speed of the exhaust blower 32 is jointly set according to the blower speed, steam speed, and distance speed of the blower of the range hood. When the blower of the range hood is at a high-speed or low-speed blower speed, the blower speed setting of the exhaust blower 32 is further strengthened, so that all the steam discharged from the exhaust port 311 can be directly sent into the smoke inlet 11, and then completely discharged outdoors through the range hood 1, avoiding the steam being discharged into the kitchen and causing the kitchen to become humid, and also avoiding the steam of the steam cooking device 3 directly blowing towards the direction where the user stands, causing the oil fume and water vapor to adhere to the user's clothes.

[0047] In a preferred embodiment of the present invention, the integrated stove further includes a steam detection component, which is communicatively connected to the controller to obtain the remaining steam volume H' in the exhaust pipe 31 through the steam detection component. The integrated stove steam emission control method further includes: setting a preset steam volume H0 for turning off the exhaust blower 32 in the controller; the steam detection component detects the remaining steam volume H' in the exhaust pipe 31 and transmits it to the controller, and the controller compares H' with H0; when H' ≤ H0, the controller turns off the exhaust blower 32.

[0048] Among them, after the steam cooking device 3 stops being used, the steam in the steam cooking device 3 will continue to be discharged within a few minutes after the steam cooking device 3 is turned off. When the exhaust blower 32 is turned off at the same time as the steam cooking device 3 is turned off, some of the remaining steam will not be able to directly enter the smoke inlet 11 through the exhaust port 311 due to insufficient power. Therefore, a steam detection component is provided in the exhaust pipe 31 or the steam cooking device 3. The steam detection component is preferably a humidity sensor for detecting the remaining steam volume H' in the exhaust pipe 31 or the steam cooking device 3. A preset steam volume H0 can be set in the controller, which can be set according to the region where it is used during factory settings. Since the climate in the south is moist, H0 can be set to 65% RH. When H' ≤ 65% RH, the controller determines that the steam in the steam cooking device 3 has been completely discharged, and then turns off the exhaust blower 32. Since the climate in the north is relatively dry, H0 can be set to 40% RH. When H' ≤ 40% RH, the controller determines that the steam in the steam cooking device 3 has been completely discharged. Further, the preset steam volume H0 can also be defined by the user. When the humidity of the kitchen is measured to be 50% RH according to the hygrometer installed in the room, when the humidity sensor detects that the steam emission volume H' in the exhaust pipe 31 or the steam cooking device 3 ≤ 50% RH and transmits it to the controller, the controller turns off the exhaust blower 32.

[0049] The steam emission control method of the integrated stove of the present invention can detect the distance value from the smoke inlet 11 to the exhaust port 311 through a height detection component, and obtain the steam emission amount of the steam cooking device 3 through the cooking program of the steam cooking device 3. When the distance value is small and the steam emission amount is large, a blower gear with a lower rotation speed can be set. When the distance value is large and the steam emission amount is large, a blower gear with a higher rotation speed is required. Under the combined action of the exhaust blower 32 and the smoke machine blower of the range hood 1, the steam of the steam cooking device 3 is directly discharged from the exhaust port 311 and enters the smoke inlet 11, avoiding high-temperature steam from condensing into small water droplets on room-temperature components and dripping onto the stove top and the kitchen cabinet countertop 6.

[0050] An integrated stove according to an embodiment of the present invention is controlled by the aforementioned steam emission control method of the integrated stove. The integrated stove further includes a heat dissipation channel 4 and a heat dissipation blower 5. The air inlet 41 of the heat dissipation channel 4 is arranged between the door 33 of the stove 2 and the steam cooking device 3. The exhaust blower 32 is arranged at the connection of the heat dissipation channel 4 and the exhaust pipe 31 to draw the air in the heat dissipation channel 4 into the exhaust pipe 31.

[0051] As Figure 2 and Figure 3 shown, the integrated stove is a split structure. The countertop of the cabinet is perforated, and the stove 2 is arranged on the countertop of the cabinet, which can avoid disassembling the countertop of the cabinet for assembling the integrated stove. The steam cooking device 3 is arranged in the cabinet and below the stove 2. A certain gap is arranged between the steam cooking device 3 and the stove 2 for arranging the heat dissipation channel 4. The heat dissipation blower 5 is arranged on the top of the steam cooking device 3 and in the heat dissipation channel 4. The air inlet 41 of the heat dissipation channel 4 is between the door 33 of the steam cooking device 3 and the stove 2. The air outlet of the heat dissipation channel 4 is communicated with the inner cavity of the stove 2, so that the air enters from the air inlet 41 and first dissipates heat from the heating part of the steam cooking device 3, and then enters the inner cavity of the stove 2 to dissipate heat from the heating part of the stove 2. The heat dissipation blower 5 provides power for the air flow. The stove 2 includes a burner and a panel. The panel is provided with holes for the burner to pass through. When the burner passes through the holes, there is a certain gap between the burner and the panel, which serves as the outlet of the air flow. When the air flows, more oxygen can be provided for the combustion of the burner at the same time.

[0052] The exhaust blower 32 is arranged in the heat dissipation channel 4 and connected to the top plate of the steam cooking device 3. The air inlet 41 of the exhaust blower 32 is communicated with the heat dissipation channel 4, and the air outlet of the exhaust blower 32 is communicated with the exhaust pipe 31, so as to draw part of the air in the heat dissipation channel 4 into the exhaust pipe 31 to provide a certain amount of power for the steam in the exhaust pipe 31 and drive the steam to flow towards the exhaust port 311.

[0053] In a preferred embodiment of the present invention, the exhaust pipeline 31 includes an exhaust cover 312 and an exhaust housing 313. The exhaust cover 312 is disposed on the exhaust housing 313 to enclose and form an exhaust cavity 314 having an air inlet 3141. The exhaust fan 32 is disposed at the air inlet 3141. The exhaust cover 312 is provided with a pipeline outlet 3121 communicating with the exhaust cavity 314. The pipeline outlet 3121 communicates with the exhaust port 311. The exhaust housing 313 is provided with a pipeline inlet 3131 communicating with the exhaust cavity 314. The pipeline inlet 3131 communicates with the inner cavity of the steam cooking device 3.

[0054] As Figures 4 to 6 shown, the exhaust cover 312 is disposed on the top of the exhaust housing 313. The left end of the exhaust cover 312 and the left end of the exhaust housing 313 enclose to form the air inlet 3141. The right end of the exhaust cover 312 is provided with the pipeline outlet 3121, and the right end of the exhaust housing 313 is provided with the pipeline inlet 3131. The air in the heat dissipation channel 4 enters the air inlet 3141 under the action of the exhaust fan 32, and converges with the steam entering the pipeline inlet 3131 through the exhaust cavity 314, thereby driving the steam into the pipeline outlet 3121.

[0055] In a preferred embodiment of the present invention, the pipeline outlet 3121 and the pipeline inlet 3131 are oppositely disposed. The cross-sectional area of the exhaust cavity 314 on the side close to the air inlet 3141 is larger than the cross-sectional area of the exhaust cavity 314 on the side close to the pipeline outlet 3121, so as to form a negative pressure at the pipeline outlet 3121 to accelerate the flow rate of the steam from the pipeline inlet 3131 to the pipeline outlet 3121.

[0056] As Figures 4 to 6 shown, the cross-sectional area of the exhaust cavity 314 on the side close to the air inlet 3141 is larger than the cross-sectional area of the exhaust cavity 314 on the side close to the pipeline outlet 3121, so that the exhaust cavity 314 forms a tapered section after the air enters the air inlet 3141, and the pipeline outlet 3121 is a tapered expansion section. According to the Venturi effect, a negative pressure is generated at the pipeline outlet 3121, thereby increasing the rising speed of the steam at the pipeline inlet and preventing the steam from flowing back.

[0057] In a preferred embodiment of the present invention, the side wall of the exhaust housing 313 is provided with a buckle 3132 extending outward, and the side wall of the exhaust cover 312 is provided with a card hole 3122. The buckle 3132 is clamped in the card hole 3122 to fixedly connect the exhaust cover 312 and the exhaust housing 313.

[0058] As Figures 4 to 6As shown, on the outer sidewall of the exhaust housing 313, there are outwardly extending buckles 3132. The buckles 3132 can be symmetrically arranged on the outer sidewalls on both sides of the exhaust housing 313, or multiple buckles 3132 can be arranged at intervals in the circumferential direction of the exhaust housing 313. The number and positions of the card holes 3122 are correspondingly set with the buckles 3132. When the buckles 3132 are inserted into the card holes 3122, the exhaust cover 312 and the exhaust housing 313 are connected in the circumferential direction to enclose and form an exhaust cavity 314 with an air inlet.

[0059] In a preferred embodiment of the present invention, on one side surface of the exhaust housing 313 close to the exhaust cover 312, there is a circumferential rib 3133, and on one side surface of the exhaust cover 312 close to the exhaust housing 313, there is a groove 3123. The circumferential rib 3133 is embedded in the groove 3123 to prevent the condensed water in the exhaust cavity 314 from flowing out of the exhaust housing 313.

[0060] As Figures 4 to 6 shown, the circumferential rib 3133 extends axially downward along the pipeline outlet 3121 or the pipeline inlet 3131. When the exhaust housing 313 and the exhaust cover 312 are fixedly connected by inserting the buckles 3132 into the card holes 3122, the circumferential rib 3133 is embedded in the groove 3123, avoiding the generation of gaps at the connection between the exhaust housing 313 and the exhaust cover 312, thereby preventing the condensed water from flowing out of the exhaust pipeline 31 through the gaps.

[0061] In a preferred embodiment of the present invention, the exhaust housing 313 is provided with an inclined surface 3134 that extends obliquely from the air inlet 3141 to the pipeline outlet 3121. The inclination angle of the inclined surface 3134 is 20° to 80°, so that the wind generated by the exhaust fan 32 can form a power completely directed towards the pipeline outlet 3121.

[0062] As Figure 4 and Figure 5 shown, the air inlet 3141 extends from left to right. The pipeline inlet 3131 and the pipeline outlet 3121 are oppositely arranged, and the axes of the pipeline outlet 3121 and the pipeline inlet 3131 are on the same straight line and are perpendicular to the air inlet 3141. In this way, after the air enters the air inlet 3141, it flows along the exhaust cavity 314. The bottom surface of the exhaust cavity 314 is the inclined surface 3134, and it extends obliquely upward from the bottom of the air inlet 3141, with an inclination angle of 20° to 80°. This makes the flow direction of the air in the exhaust cavity 314 follow the flow direction of the steam, so that the wind generated by the air flowing in the exhaust cavity 314 generates an upward power on the steam, driving the steam to flow from the pipeline inlet to the pipeline outlet 3121 faster.

[0063] In a preferred embodiment of the present invention, the exhaust cover 312 and / or the exhaust housing 313 are provided with inwardly protruding water retaining ribs 315 to prevent the condensed water from being discharged from the air inlet 3141.

[0064] As Figure 4 and Figure 5 shown, the exhaust cover 312 is located above the exhaust housing 313. Since the flow direction of the condensed water is downward, a water retaining rib 315 is provided at the inclined surface 3134 of the exhaust housing 313 near the pipeline inlet 3131 to prevent the condensed water generated during the process from the pipeline inlet 3131 to the exhaust port 311 from draining to the air inlet 3141 through the inclined surface 3134, thereby avoiding the condensed water from entering the heat dissipation channel 4.
