Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and in particular to a multifunctional elevator. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building. Its car runs on at least two rows of rigid tracks that are perpendicular to the horizontal plane or have an inclination angle of less than 15° to the plumb line. The size and structure of the elevator car must be convenient for passengers to enter and exit or load and unload goods.

[0003] In some application scenarios, in addition to the vertical transportation function, multifunctional elevators with other functions are also required to be suitable for certain application scenarios with special needs. For example, multifunctional elevators used in public health places such as hospitals and workshops with high dust content need to be integrated with air purification functions to ensure that the air entering the cabin is clean and can be continuously renewed to provide passengers with a comfortable and safe user experience.

[0004] In the prior art, an air purification function is integrated into an elevator by adopting the following method: a built-in air purification device is used, a filter is used to filter dust in the air, a disinfectant or ultraviolet light is used to eliminate bacteria in the air, and activated carbon is used to absorb harmful gases to keep the air fresh and provide passengers with a comfortable riding environment. However, a filter is used to filter dust in the air, and the filter has a good filtering effect, but dust particles accumulate on the surface of the filter quickly, and a higher frequency of manual replacement is required, which increases the labor cost and the material cost of the filter. Summary of the invention

[0005] In view of the technical problem in the prior art that a multifunctional elevator with integrated air purification function needs to keep the air in the car clean and constantly updated, the present invention provides a multifunctional elevator, in which the air entering the elevator car is filtered and sterilized, and the air in the car is constantly updated to keep the air in the car clean and hygienic, thereby improving the user experience of the elevator; and the filtered dust particles can be automatically cleaned.

[0006] The present invention provides a multifunctional elevator, comprising a car, and further comprising: an air intake assembly, the air intake assembly comprising an air inlet, a first air duct and a fan, the air intake assembly being arranged at an upper portion outside the car; an air filter assembly, the air filter assembly comprising a second air duct, the second air duct being communicated with the first air duct, an air filter being arranged in the second air duct, the air filter comprising a rotating plate, the vertical cross-section of the inner cavity of the second air duct being semicircular, the rotating plate being arranged at an upper portion of the second air duct and being sealed and connected to the second air duct, a plurality of brush strips being fixed to one side of the rotating plate, the brush strips being interference-connected to the inner wall of the second air duct, and the rotating plate being connected to a first driving member for driving the rotating plate to rotate The invention relates to an assembly, wherein the air filtering assembly is arranged at the upper part outside the car, a connecting block arranged along the axial direction of the second air tube is arranged in the middle part of the rotating plate, one end of the brush strip is fixed to the connecting block along the cross-sectional direction perpendicular to the second air tube, and the other end of the brush strip radiates toward the inner cavity wall of the second air tube along the circumferential direction; a sterilization assembly, wherein the sterilization assembly comprises a third air tube, the third air tube is connected to the second air tube, a valve is arranged between the third air tube and the second air tube, and an ultraviolet lamp is arranged in the third air tube along its axial direction; an exhaust assembly, wherein the exhaust assembly comprises a fourth air tube, a part of the fourth air tube extends into the car, and an air outlet is arranged in the car.

[0007] Furthermore, the air inlet assembly includes an upper air inlet and a lower air inlet, and the upper air inlet and the lower air inlet are connected to the first air duct. The upper air inlet faces upward, and the lower air inlet faces downward. When the elevator rises or descends, the corresponding air intake of the upper air inlet and the lower air inlet increases, increasing the air volume entering the ventilation assembly, and finally increasing the air volume entering the car, achieving a better ventilation effect; at the same time, it can reduce the requirements for the fan speed, reduce costs or increase the service life of the fan.

[0008] Furthermore, along the length direction of the brush strip, the ratio of the distance from the position where the brush strip and the rotating plate are connected to the inner cavity wall of the second air duct to the length of the brush strip is 1:1.05-1.1.

[0009] The distance from the connection position of the brush strip and the rotating plate to the inner cavity wall of the second air duct is shorter than the length of the brush strip. The brush strip abuts against the inner cavity wall of the second air duct and there is an extra section of the brush strip. When the rotating plate drives the brush strip to rotate, the brush strip interacts with the inner cavity wall of the second air duct, thereby vibrating the brush strip and causing the dust particles on the brush strip to be shaken off the brush strip. The rotation of the rotating plate separates the rotating plate from the second air duct, and as the rotating plate rotates, the gap between the two becomes larger and larger, until the rotating plate rotates 90° and the gap between the two is the largest, and then as the rotating plate rotates again, the gap between the two decreases. First, close the valve between the third air duct and the second air duct, and the wind generated by the fan will blow the dust particles shaken off the brush strip out of the second air duct. After the set time is up, the rotating plate rotates back to the initial position.

[0010] Furthermore, along the plane direction of the axial direction of the second air cylinder, a plurality of brush strips are evenly arranged in a staggered manner. Dust particles in the wind introduced by the air inlet come into contact with the brush strips and are blocked by the evenly arranged brush strips in a staggered manner. The evenly arranged staggered brush strips have a better filtering effect on dust particles and a better air cleaning effect on the incoming wind, thereby making the wind entering the car cleaner.

[0011] Furthermore, the first drive assembly includes a rotating rod, which is fixedly connected to the rotating plate, arranged along the axial direction of the second air cylinder and disposed in the middle of the vertical section of the rotating plate, the rotating rod is connected to a worm gear, the worm gear is connected to a worm, the worm gear is connected to a motor that drives the worm gear to rotate, the motor is fixed to a motor bracket, and the motor bracket is fixed to the outside of the upper wall of the car.

[0012] Furthermore, an upper lamp trough and a lower lamp trough for fixing the ultraviolet lamp are arranged in the inner cavity of the third wind tube, an upper guard plate 1 is arranged on the side of the upper lamp trough facing the second wind tube, and an upper guard plate 2 is arranged on the side of the upper lamp trough facing away from the second wind tube for limiting the movement of the ultraviolet lamp along the axial direction of the upper lamp trough; a lower guard plate 1 is arranged on the side of the lower lamp trough facing the second wind tube, and a lower guard plate 2 is arranged on the side of the lower lamp trough facing away from the second wind tube for limiting the movement of the ultraviolet lamp along the axial direction of the lower lamp trough; an upper support plate for supporting the ultraviolet lamp is arranged at the lower part of the upper lamp trough, and a lower support plate for limiting the ultraviolet lamp is arranged at the upper part of the lower lamp trough, and both the upper support plate and the lower support plate are provided with through holes for ultraviolet rays to pass through. The upper guard plate 1 and the lower guard plate 1 block the wind from the second wind tube from blowing to the ultraviolet lamp, thereby playing a protective role. The upper guard plate 2 and the lower guard plate 2 limit the ultraviolet lamp. The ultraviolet lamp is inserted into the upper lamp groove or the lower lamp groove, and then the upper guard plate 2 or the lower guard plate is fixed with bolts. The upper guard plate 2 or the lower guard plate 2 is provided with a hole for the wire of the ultraviolet lamp to pass through. The upper support plate and the lower support plate are formed by opening the inner wall of the third wind tube.

[0013] Furthermore, a fourth air tube is provided between the sterilization component and the air filter component, at least one layer of filter screen is provided in the fourth air tube, the filter screen is fixed in the filter frame, and a slot is provided on the side wall of the fourth air tube so that the filter frame is plugged and sealed in the fourth air tube. The filter screen is fixed in the filter frame, and the filter frame is plugged in the fourth air tube, so that installation and replacement are more convenient, and at least one layer of filter screen can filter the wind more finely and achieve a better filtering effect.

[0014] Furthermore, the exhaust assembly includes an exhaust duct, the part of the exhaust duct located in the car is fixed to the rear side wall of the car, and a windshield is provided on the side of the exhaust duct facing the front side wall of the car. The windshield is provided to block and buffer the wind, preventing the wind blown into the car from directly blowing on the body of the passengers, causing a bad user experience for the passengers.

[0015] Furthermore, an upper air outlet is provided at one end of the upper side wall of the car toward the front side wall of the car, and a lower air outlet is provided at one end of the lower side wall of the car toward the front side wall of the car. The air blown into the car from the rear side wall, and the air blown out of the rear side wall goes to the upper air outlet and the lower air outlet, and the air goes from the rear side wall to the upper and lower positions close to the front side wall, so that the air entering the car has a more sufficient circulation effect in the car, so that there is sufficient gas exchange in the car, ensuring the cleanliness of the air in the car, and bringing a better riding experience to passengers.

[0016] The beneficial effects of the present invention are:

[0017] The air entering the elevator car is filtered and sterilized, and the air in the car is constantly updated, keeping the air in the car clean and hygienic, and improving the elevator user experience. The air filter component is set to retain the dust particles brought in by the wind in the air filter. When the dust particles accumulate to a certain extent after long-term use, the valve is closed and the rotating plate is driven to rotate to realize automatic cleaning of the dust particles, so as to maintain the long-term use of the air filter component and reduce inconvenient manual maintenance and replacement.

[0018] The distance from the position where the brush strip is connected to the rotating plate to the inner cavity wall of the second air duct is slightly shorter than the length of the brush strip. One end of the brush strip is fixed to the connecting block, and the other end of the brush strip radiates toward the inner cavity wall of the second air duct in a fan-shaped manner and abuts against the inner cavity wall of the second air duct. The rotating plate drives the brush strip to rotate during rotation, and the interaction between the brush strip and the wall of the second inner cavity causes the brush strip to vibrate as the rotating plate rotates, thereby dropping dust particles attached to the brush strip. During the rotation of the rotating plate, multiple brush strips can generate long-term vibrations with the inner cavity wall of the second air duct, thereby achieving a better effect of removing dust particles filtered by the brush strip.

[0019] The windshield is set to block and buffer the wind, preventing the wind blowing into the car from directly blowing on the passengers' bodies and causing a bad experience for the passengers. The wind blows into the car from the rear wall of the car, and the wind blown out of the rear wall goes to the upper and lower air outlets. The wind goes from the rear wall to the upper and lower positions close to the front wall, so that the wind entering the car has a more sufficient circulation effect in the car, so that there is sufficient gas exchange in the car, ensuring the cleanliness of the air in the car, and bringing a better riding experience to passengers.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0025] like Figure 1As shown, an embodiment of the present invention provides a multifunctional elevator, including a car 6, an air inlet assembly is arranged on the upper part outside the car 6, the air inlet assembly includes an air inlet, a first air duct 11 and a fan, the air inlet assembly includes an upper air inlet 12 and a lower air inlet 13, the upper air inlet 12 and the lower air inlet 13 merge into the first air duct 11, the fan is arranged in the first air duct 11, the motor drives the fan to rotate, the negative pressure generated by the rotation of the fan draws external air from the upper air inlet 12 or the lower air inlet 13 to generate airflow, the upper air inlet 12 faces upward, and the lower air inlet 13 faces downward, when the elevator rises or descends, the corresponding air intake volume of the upper air inlet 12 and the lower air inlet 13 increases, the air volume entering the ventilation assembly is increased, and finally the air volume entering the car 6 is increased, which has a better ventilation effect; at the same time, it can reduce the requirements on the fan speed, reduce costs or increase the service life of the fan. In order to make the air intake of the upper air inlet 12 and the lower air inlet 13 have little or no influence on each other, in a preferred embodiment, the upper air inlet 12 and the lower air inlet 13 are not directly connected in a straight line, and the wind entering from the upper air inlet 12 blows downward to the cylinder wall, then bends and enters the first air duct 11, and the wind entering from the lower air inlet 13 blows upward to the cylinder wall and then bends and enters the first air duct 11. In a preferred embodiment, the lower air inlet 13 is raised a distance above the car 6 to facilitate air intake, and the first air duct 11 is supported by a bracket on the upper part of the car 6, so that the lower air inlet 13 and the upper air inlet 12 are raised.

[0026] like Figure 2As shown, the air filter assembly is arranged at the upper part outside the car 6, and the air filter assembly includes a second air cylinder 22, and the second air cylinder 22 is connected to the first air cylinder 11, and an air filter is arranged in the second air cylinder 22. The wind blown in from the first air cylinder 11 enters the second air cylinder 22, passes through the air filter, and the air filter filters the wind, and the dust particles carried in the wind are retained in the air filter. The air filter includes a rotating plate 211, and the vertical section of the inner cavity of the second air cylinder 22 is semicircular. The rotating plate 211 is arranged at the upper part of the second air cylinder 22 and is sealed with the second air cylinder 22. A plurality of brush strips 212 are fixed on one side of the rotating plate 211, and the brush strips 212 are interference-connected with the inner wall of the second air cylinder 22. A plurality of brush strips 212 are arranged in the inner cavity of the second air duct 22. The wind in the inner cavity of the second air duct 22 contacts the brush strips 212, and the brush strips 212 cause the direction of the wind to change continuously. The dust particles in the wind continue to maintain their original direction of movement due to inertia, thereby separating from the wind, hitting the brush strips 212, and being retained on the surface of the brush strips 212. In this embodiment, the brush strip 212 is interference-connected with the inner wall of the second air cylinder 22, that is, along the length direction of the brush strip 212, the distance from the connection position of the brush strip 212 and the rotating plate 211 to the inner cavity wall of the second air cylinder 22 is slightly shorter than the length of the brush strip 212.

A valve 31 is provided between the third air tube 33 and the second air tube 22. After the valve 31 is closed, the rotating plate 211 is rotated, and the rotating plate 211 rotates so that the upper part of the second air tube 22 is opened and in contact with the outside world. The fan in the first air tube 11 rotates and continuously supplies air to the second air tube 22. The wind blows a large amount of dust particles dropped from the brush strip 212 due to the rotation of the rotating plate 211 out of the second air tube 22, so as to clean the brush strip 212. In the process of cleaning the brush strip 212, the rotating plate 211 can keep rotating so that the brush strip 212 is constantly vibrating to achieve a better cleaning effect. The rotating plate 211 can also be rotated by an angle, such as 90°, to increase the cleaning time and achieve a better cleaning effect. After the brush strip 212 is cleaned, the rotating plate 211 is reset and sealed with the second air tube 22. In order to make the rotating plate 211 and the second air tube 22 sealed, a sealing elastic cushion layer 2112 is wrapped on the outer side of the rotating plate 211, so that the rotating plate 211 seals the upper part of the second air tube 22.
