TECHNICAL FIELD
[0001] The utility model relates to the field of kitchen range hood, especially a folding range hood cover and a motor home. BACKGROUND
[0002] With the popularity of motor home travel, more and more people choose to enjoy the fun of cooking during the journey. However, the internal space of the motor home is limited, and the traditional range hood usually adopts a fixed design with a large volume, which further compresses the available space when installed in the narrow kitchen area of the motor home, affecting user activities.
[0003] At present, a range hood is disclosed in Chinese patent application No. CN2303193Y, published on January 6, 1999, which includes an exhaust fan and a foldable cover. The cover includes a front cover plate and a rear cover plate connected to each other at the top, a spiral torsion spring arranged on the connecting shaft of the front cover plate and the rear cover plate, and a foldable fan-shaped left side cover and a right side cover connected to the left and right sides of the front cover plate and the rear cover plate.
[0004] In use, the rear cover plate is fixedly arranged, and the front cover plate is rotated around the connection at the top of the rear cover plate, so that the cover can be folded or unfolded. During the rotation of the front cover plate, the fan-shaped left side cover and the right side cover will be folded or unfolded accordingly.
[0005] With respect to the above-mentioned related technology, the torsion spring between the front cover plate and the rear cover plate supports the unfolded front cover plate when the cover is unfolded. However, the torsion spring will lose its elasticity with aging, especially when it is corroded by oil fume, which will accelerate the aging of the spring and cause the front cover plate to be unstable when the cover is unfolded, posing a safety risk. UTILITY MODEL CONTENTS
[0006] In order to improve the stability of the foldable range hood cover when it is unfolded, the utility model provides a folding range hood cover and a motor home.
[0007] First aspect: the utility model provides a folding range hood cover, adopts the following technical scheme:
[0008] A folding range hood cover includes a main cover body and a side cover body. The upper part of the main cover body is rotationally connected to a fixed surface. The side cover body is rotationally connected to the side of the main cover body. The side cover body includes a first side cover body and a second side cover body. The first side cover body is rotationally connected to the side of the main cover body. The second side cover body is rotationally connected to the fixed surface. The first side cover body and the second side cover body are rotationally connected. When the range hood cover is unfolded, the side edges of the first side cover body and the second side cover body that are relatively close to each other abut each other. The first side cover body abuts the main cover body, and the second side cover body abuts the fixed surface. The first side cover body and the second side cover body are locked at the maximum angle by a locking mechanism.
[0009] By adopting the technical scheme, when the range hood cover is folded, the locking mechanism is opened, the first side cover body and the second side cover body are rotated towards the inside of the main cover body, the main cover body is automatically folded downward under the action of gravity, and the first side cover body and the second side cover body are folded between the main cover body and the fixed surface; when the range hood cover is unfolded, the main cover body is folded upward, and the first side cover body and the second side cover body are rotated towards the outside of the main cover body, so that the first side cover body and the second side cover body are unfolded, at this time, the first side cover body abuts against the main cover body, the second side cover body abuts against the fixed surface, and the side portions of the first side cover body and the second side cover body that are relatively close to each other abut against each other, and the locking mechanism is used to fix the first side cover body and the second side cover body at the current position, so that the first side cover body and the second side cover body can support the main cover body in the unfolded state. In this way, the range hood cover can be unfolded during use and folded after use, thereby saving space; meanwhile, when the range hood cover is unfolded, the main cover body is supported and fixed by the side cover bodies, the stability of the range hood cover in the unfolded state is improved, and the safety hidden danger is reduced.

By arranging the flexible hinge with elasticity to connect the first side cover body and the second cover body, the first side cover body and the second cover body can be folded by themselves under the action of the elasticity, facilitating the folding and storage of the cover.
[0016] Optionally, the elastic member is an elastic rope, one end of the elastic rope is connected to the outside of the first side cover body, and the other end of the elastic rope is connected to the outside of the second side cover body.
[0017] By adopting the technical scheme, the two ends of the elastic rope are connected to the outer sides of the first side cover body and the second side cover body respectively and have a contraction tendency, so that the elastic rope has a tendency to pull the first side cover body and the second side cover body, and since the pulling direction of the elastic rope is transmitted along the direction in which the elastic rope is elongated, when the range hood cover is unfolded, the first side cover body and the second side cover body are arranged in a coplanar manner, at this time, if the elastic rope is arranged in parallel with the first side cover body, the pulling direction of the elastic rope is transmitted in the direction in which the first side cover body and the second side cover body are coplanar, and the first side cover body and the second side cover body cannot be pulled to rotate and fold, arranging the two ends of the elastic rope at an angle with the first side cover body and the second side cover body or arranging the first side cover body and the second side cover body in a non-coplanar manner can make the pulling force of the elastic rope transmitted to the outer sides of the first side cover body and the second side cover body through the ends of the elastic rope and generate a component force perpendicular to the direction of the outer sides of the first side cover body and the second side cover body, and then pull the first side cover body and the second side cover body to rotate towards the inner side of the main cover body, so as to realize automatic folding of the side cover bodies towards the inner side. In this way, by arranging the elastic rope, the first side cover body and the second side cover body can be automatically folded towards the inner side under the action of the elastic rope when the range hood cover is folded, and folding and storage of the range hood cover are facilitated.
[0018] Optionally, the electric push rod is further arranged, one end of the electric push rod is rotationally connected to the main cover body, and the other end of the electric push rod is rotationally connected to the fixed surface.
[0019] By adopting the technical scheme, the electric push rod is arranged below the main cover body, when the electric push rod is elongated, the end of the electric push rod connected to the main cover body and the main cover body rotate relative to each other, and the main cover body is lifted in a manner of rotating around the top, and the electric push rod can support the main cover body when the electric push rod is fixed; when the electric push rod is contracted, the electric push rod drives the main cover body to rotate and fold, and the side cover bodies are automatically folded towards the inner side under the action of the elastic member.
