Abstract
A direct-exhaust range hood special for a motor home comprises a fan which is arranged on a door and window or a hole which can be opened on a motor home body or is extended to the outside of the motor home body through the hole by a pipeline, and a speed regulator and a switch for controlling the fan. The cooking stove body for cooking is arranged on the side surface or the upper part of the smoke suction port of the range hood. When cooking, oil smoke enters the fan through the smoke suction port and is directly discharged to the outside of the vehicle body after being accelerated by the fan.
Description
Technical Field
The invention relates to the field of range hoods, and particularly belongs to the field of range hoods special for motor homes.
Background
Most of the existing car-home range hoods in the market are used for removing tires, a fan is arranged in an air inlet of the range hood, and a pipeline with an opening sectional area approximately similar to an air outlet of the fan is connected with the fan to discharge oil smoke out of a car. However, in practical use, people find that the effect of oil smoke exhaust of the range hood of the motor home is not ideal, so that a plurality of motor homes have to be externally provided with cooking benches, and a motor home can cook in a severe environment where wind blows, sun and rain.
In addition, although a side-discharging type range hood is not connected through a pipeline and directly discharges oil smoke outside the vehicle by adopting an axial flow fan, the range hood is provided with a shell outside the vehicle body in order to prevent rain, and the shell forces airflow to deflect by about 90 degrees and then can be vertically discharged downwards. This also results in an undesirable effect of oil smoke extraction, far from comparable to domestic range hoods.
After a great deal of research, the reason for poor oil fume exhaust effect of the house vehicle range hood is found as follows: although the domestic range hood is moved by the aid of the structural design of the domestic range hood, a built-in fan and a smoke exhaust pipe are adopted to exhaust smoke, the fan power of the domestic range hood is as high as 200-300 watts, a centrifugal fan with high exhaust pressure is adopted, the diameter of an exhaust pipeline is over 160MM, the diameter of a smoke exhaust pipeline of a range hood with a large suction force is as high as 200MM, the domestic range hood generally adopts an axial flow fan with dozens of watts and low exhaust pressure, the radial flow fan is limited by the space of a motor home, the diameter of the exhaust pipeline is only about 100MM and is influenced by the installation position, oil smoke needs to be discharged out of the motor home only by being bent seven turns and eight turns in the pipeline, and accordingly high-speed airflow discharged by the axial flow fan is increased in exhaust resistance after the high-speed airflow turns in the pipeline in a seven turns and eight turns, and the exhaust.
The side-discharge range hood also deflects airflow in a limited space to increase exhaust pressure and influence exhaust efficiency due to the same reason.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a direct-exhaust type range hood technology special for a motor home.
The technology can be implemented by the following scheme that the in-line range hood special for the motor home comprises a fan, a speed regulator and a switch, wherein the fan is installed on a door and a window or a hole of a motor home body, and the door and the hole can be opened, or is extended to the outside of the motor home body through a pipeline and the hole, and the speed regulator and the switch control the fan. The cooking stove body for cooking is arranged on the side surface or the upper part of the smoke suction port of the range hood. When cooking, oil smoke enters the fan through the smoke suction port and is directly discharged to the outside of the vehicle body after being accelerated by the fan.
Preferably, the fan is an axial flow fan, and the axial flow fan has a larger exhaust flow than the centrifugal fan under the same power. But when the smoke discharge angle needs to be converted by 90 degrees, the centrifugal fan is more efficient.
Preferably, the smoke suction port is positioned on the side surface of the cooking bench, so that the smoke suction port can be closer to the pot, and the smoke suction efficiency is higher.
Preferably, the fan is installed by utilizing the furniture structure in the vehicle body, and the flue is formed, so that the sectional area of the flue is larger, and smoke discharge is smoother.
Preferably, the invention can also use the flexible pipe with the sectional area more than 3 times of the sectional area of the air outlet of the fan to discharge smoke, increase the sectional area of the smoke discharge pipe, be favorable for reducing the resistance of the smoke discharge and improve the smoke discharge efficiency.
Preferably, the range hood disclosed by the invention can be used for hiding the air inlet of the range hood by arranging a switch panel or making a sliding rail into a drawing structure.
Compared with the existing range hood, the range hood has the advantages that the range hood is very obvious in beneficial effect, the efficiency of the range hood is greatly improved, the problem that dishes are difficult to fry in a car in a caravan boundary for a long time is solved, a cooking bench outside the car has to be arranged, and the embarrassment that the dishes are fried is attracted and cannot be returned again.
