Description

Technical Field

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

[0002] An elevator refers to a permanent transportation device that serves several specific floors in a building, and its car moves on at least two rigid tracks perpendicular to the horizontal plane or with an inclination angle less than 15° from the plumb line. The car size and structural form of the elevator should facilitate the entry and exit of passengers or the loading and unloading of goods.

[0003] In some application scenarios, in addition to the vertical transportation function, a multifunctional elevator integrated with other functions is required to be applicable to some application scenarios with special requirements. For example, multifunctional elevators used in public health places such as hospitals and workshop places with a large amount of dust need to integrate an air purification function to make the air cleanliness in the car higher and continuously update the air in the car, so as to give passengers a comfortable and safe user experience.

[0004] In the prior art, to integrate an air purification function in an elevator, the method adopted is: an air purification device is built in, a filter screen is used to filter dust in the air, disinfectant or ultraviolet lamps are used to kill bacteria in the air, activated carbon is used to adsorb harmful gases, so as to keep the air fresh and provide a comfortable riding environment for passengers. However, when using a filter screen to filter dust in the air, the filtering effect of the filter screen is good, but dust particles accumulate quickly on the surface of the filter screen, and it is necessary to replace it manually at a relatively high frequency, which increases the labor cost and the material cost of the filter screen. Summary of the Invention

[0005] Aiming at the technical problem that in the prior art, for a multifunctional elevator integrated with an air purification function, it is necessary to keep the air in the car clean and continuously update it, the present invention provides a multifunctional elevator. The air entering the elevator car is filtered and sterilized, the air in the car is continuously updated, and the air in the car is kept clean and hygienic, so as to improve the use experience of the elevator; moreover, the filtered dust particles can be automatically cleaned.

[0006] The present invention provides a multifunctional elevator, including a car, and further including: an air intake component, which includes an air intake port, a first air duct and a fan, and is arranged at the upper part outside the car; a filter air component, which includes a second air duct, the second air duct is communicated with the first air duct, a filter air member is arranged in the second air duct, the filter air member includes a rotating plate, the vertical cross-section of the inner cavity of the second air duct is semicircular, the rotating plate is arranged at the upper part of the second air duct and is hermetically connected with the second air duct, a plurality of brush strips are fixed on one side of the rotating plate, the brush strips are in interference connection with the inner wall of the second air duct, the rotating plate is connected with a first driving component for driving the rotating plate to rotate, the filter air component is arranged at the upper part outside the car, a connecting block arranged along the axial direction of the second air duct is arranged in the middle of the rotating plate, along the cross-section direction perpendicular to the second air duct, one end of the brush strip is fixed on the connecting block, and the other end of the brush strip radiates along the circumferential direction towards the inner cavity wall of the second air duct; a sterilization component, which includes a third air duct, the third air duct is communicated with the second air duct, a valve is arranged between the third air duct and the second air duct, and an ultraviolet lamp is arranged along the axial direction in the third air duct; an exhaust component, which includes a fourth air duct, a part of the fourth air duct extends into the car, and an air outlet is arranged in the car.

[0007] Further, the air intake component includes an upper air intake port and a lower air intake port, and the upper air intake port and the lower air intake port converge into the first air duct. The upper air intake port faces upwards, and the lower air intake port faces downwards. When the elevator ascends or descends, the air intake amounts of the upper air intake port and the lower air intake port increase correspondingly, the air volume entering the ventilation component increases, and finally the air volume entering the car increases, achieving a better ventilation effect; at the same time, the requirement for the fan speed can be reduced, the cost can be reduced or the service life of the fan can be prolonged.

[0008] Further, along the length direction of the brush strip, the ratio of 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 to the length of the brush strip is 1:1.05 - 1.1.

[0009] 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 shorter than the length of the brush strip. The brush strip abuts against the wall of the inner cavity of the second air duct and there is still a surplus 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, so that the brush strip vibrates, and the dust particles on the brush strip are shaken off the brush strip; when the rotating plate rotates, the gap between the rotating plate and the second air duct is separated, and as the rotating plate rotates, the gap between the two becomes larger and larger until the rotating plate rotates 90°, the gap between the two is the largest, and then as the rotating plate rotates, the gap between the two decreases; first, the valve between the third air duct and the second air duct is closed, and the wind generated by the fan blows the dust particles shaken off the brush strip out of the second air duct. After the set time arrives, 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 facing 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 facing the front side wall of the car. The air blows into the car from the rear side wall, and the air blown out from the rear side wall reaches the upper air outlet and the lower air outlet. The air goes from the rear side wall to the upper and lower positions close to the front side wall, enabling the air entering the car to have a more sufficient circulation effect inside the car, ensuring sufficient gas exchange inside the car, guaranteeing the air cleanliness inside the car, and bringing a better riding experience to passengers.

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

[0017] The air entering the elevator car is filtered and sterilized, continuously updating the air inside the car, maintaining the air cleanliness and hygiene inside the car, and improving the use experience of the elevator. The air filter component is provided to retain the dust particles carried by the air in the air filter element. 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 achieve automatic cleaning of the dust particles, maintaining the long-term use of the air filter component and reducing 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 fan-shaped towards the inner cavity wall of the second air duct and abuts against the inner cavity wall of the second air duct. During the rotation of the rotating plate, the brush strip is driven to rotate. The interaction between the brush strip and the wall of the second inner cavity causes the brush strip to vibrate when rotating with the rotating plate, and the dust particles attached to the brush strip fall off. During the rotation of the rotating plate, multiple brush strips can vibrate with the inner cavity wall of the second air duct for a long time, thereby achieving a better effect of cleaning the dust particles filtered by the brush strip.

[0019] The wind deflector is provided to block and buffer the wind, preventing the wind blown into the car from directly blowing on the passengers' bodies and causing an adverse use experience to the passengers. The air blows into the car from the rear side wall of the car, and the air blown out from the rear side wall reaches the upper air outlet and the lower air outlet. The air goes from the rear side wall to the upper and lower positions close to the front side wall, enabling the air entering the car to have a more sufficient circulation effect inside the car, ensuring sufficient gas exchange inside the car, guaranteeing the air cleanliness inside the car, and bringing a better riding experience to passengers.

Detailed implementation manners

[0030] To enable those skilled in the art to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0031] As Figure 1 shown, an embodiment of the present invention provides a multi-functional elevator, including a car 6. An air inlet assembly is provided at 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 converge 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 sucks the external air from the upper air inlet 12 or the lower air inlet 13 to generate an air flow. The upper air inlet 12 faces upward, and the lower air inlet 13 faces downward. When the elevator goes up or down, the air intake of the upper air inlet 12 and the lower air inlet 13 increases correspondingly, increasing the amount of air entering the ventilation assembly, and finally increasing the amount of air entering the car 6, 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. To make the air intake of the upper air inlet 12 and the lower air inlet 13 have less or no mutual 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. The air entering from the upper air inlet 12 blows downward to the barrel wall and then bends into the first air duct 11. The air entering from the lower air inlet 13 blows upward to the barrel wall and then bends into the first air duct 11. In a preferred embodiment, the lower air inlet 13 is raised by a certain distance above the car 6 to facilitate air intake. The first air duct 11 is supported by a bracket at the upper part of the car 6, so that the lower air inlet 13 and the upper air inlet 12 are raised.

[0032] As Figure 2As shown in the figure, the air filtering component is arranged at the upper part outside the car 6. The air filtering component includes a second air duct 22 which is communicated with a first air duct 11. A filtering member is arranged in the second air duct 22. The air blown into the first air duct 11 enters the second air duct 22 and passes through the filtering member. The filtering member filters the air and retains the dust particles carried in the air on the filtering member. The filtering member includes a rotating plate 211. The vertical cross-section of the inner cavity of the second air duct 22 is semi-circular. The rotating plate 211 is arranged at the upper part of the second air duct 22 and is hermetically connected with the second air duct 22. A plurality of brush strips 212 are fixed on one side of the rotating plate 211. The brush strips 212 are in interference connection with the inner wall of the second air duct 22. The plurality of brush strips 212 are arranged in the inner cavity of the second air duct 22. Through the contact between the air in the inner cavity of the second air duct 22 and the brush strips 212, the brush strips 212 continuously change the direction of the air. The dust particles in the air will continue to maintain their original moving direction due to inertia, so as to be separated from the air, hit the brush strips 212 and are retained on the surface of the brush strips 212 by the brush strips 212. In this embodiment, the brush strips 212 are in interference connection with the inner wall of the second air duct 22, that is, along the length direction of the brush strips 212, the distance from the position where the brush strips 212 are connected with the rotating plate 211 to the inner cavity wall of the second air duct 22 is slightly shorter than the length of the brush strips 212. Preferably, along the length direction of the brush strips 212, the length ratio between the distance from the position where the brush strips 212 are connected with the rotating plate 211 to the inner cavity wall of the second air duct 22 and the length of the brush strips 212 is 1:1.05 - 1.1. During the rotation of the rotating plate 211, the brush strips 212 are driven to rotate. The interaction between the brush strips 212 and the wall of the second inner cavity causes the brush strips 212 to vibrate when rotating with the rotating plate 211, and the dust particles attached to the brush strips 212 fall off. A valve 31 is arranged between the third air duct 33 and the second air duct 22. After closing the valve 31, the rotating plate 211 is rotated. The rotation of the rotating plate 211 opens the upper part of the second air duct 22 to contact the outside. The fan in the first air duct 11 rotates and continuously sends air to the second air duct 22. The air flow blows out a large number of dust particles falling from the brush strips 212 due to the rotation of the rotating plate 211 from the second air duct 22, realizing the cleaning of the brush strips 212. During the cleaning process of the brush strips 212, the rotating plate 211 can keep rotating all the time to make the brush strips 212 vibrate continuously so as to achieve a better cleaning effect. Or the rotating plate 211 can be rotated by an angle, such as 90°, to increase the cleaning time and achieve a better cleaning effect. After the cleaning of the brush strips 212 is completed, the rotating plate 211 is reset and hermetically connected with the second air duct 22. To make the rotating plate 211 hermetically connected with the second air duct 22, a sealing elastic cushion layer 2112 is wrapped outside the rotating plate 211, so that the rotating plate 211 seals the upper part of the second air duct 22.

[0033] The brush strips 212 are regularly and evenly arranged on one side of the rotating plate 211. In a preferred embodiment, multiple rows of brush strips 212 are staggered and evenly arranged along the axial direction of the second air cylinder 22 to improve the retention effect of dust particles, thereby improving the filtering and cleaning effect of the wind. Figure 3 As shown, in one embodiment, a connection block 2111 arranged along the axial direction of the second air cylinder 22 is provided in the middle of the rotating plate 211, and along the cross-sectional direction perpendicular to the axial direction of the second air cylinder 22, one end of the brush strip 212 is fixed to the connection block 2111, and the other end of the brush strip 212 radiates toward the inner cavity wall of the second air cylinder 22 in a fan-shaped manner and abuts against the inner cavity wall of the second air cylinder 22. Figure 4 As shown, in one embodiment, when the rotating plate 211 seals the second air cylinder 22 horizontally, the brush strip 212 is vertically arranged, one end of the brush strip 212 is fixedly connected to the rotating plate 211 , and the other end of the brush strip 212 abuts against the inner cavity wall of the second air cylinder 22 .

[0034] like Figures 2 - 5 As shown, when the rotating plate 211 is installed, the rotating plate 211 is first installed on the upper part of the second wind tube 22, and then the fixed plate 221 is fixed to the side of the second wind tube 22 facing away from the first wind tube 11. The fixed plate 221 is fixedly connected to the second wind tube 22, one end of the rotating plate 211 in the axial direction abuts against the inner wall of the second wind tube 22, and the other end of the rotating plate 211 in the axial direction abuts against the fixed plate 221. The inner cavity of the second wind tube 22 is sealed by the second wind tube 22, the rotating plate 211 and the fixed plate 221. The rotating rod 213 is connected to the rotating plate 211 by interference fit and is fixedly connected to the rotating plate 211 by bolts. The rotating rod 213 extends from one end of the rotating plate 211 toward the fixed plate 221, and is connected to the first driving assembly and driven to rotate by the first driving assembly. In a preferred embodiment, the rotating rod 213 passes through both ends of the rotating plate 211, and a rotating groove 222 is provided at a corresponding position on one side of the second air cylinder 22 facing the first air cylinder 11 to accommodate one end of the rotating rod 213. The setting of the rotating groove 222 plays a limiting role in the movement of the rotating rod 213 in a direction perpendicular to its axial direction, so that the rotating plate 211 will not be separated from the second air cylinder 22 when rotating around the rotating rod 213, so that the device can operate stably. The rotating plate 211 is driven to rotate by a first driving assembly, and the first driving assembly includes a rotating rod 213, the rotating rod 213 is fixedly connected to the rotating plate 211, the rotating rod 213 is arranged along the axial direction of the second air cylinder 22 and the rotating rod 213 is arranged in the middle of the vertical section of the rotating plate 211, the rotating rod 213 is connected to a worm wheel, the worm wheel is connected to a worm, the worm is connected to a motor that drives the worm 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 6. The first driving assembly is controlled by automation to set a start cycle, and the first driving assembly is not shown in the drawings.

[0035] like Figure 6As shown in the figure, the sterilization component includes a third air duct 33. The third air duct 33 is communicated with the second air duct 22. Ventilation holes 511 are formed in the peripheral wall of the second air duct 22 to communicate with the third air duct 33. The axial direction of the third air duct 33 is perpendicular to the axial direction of the second air duct 22. A valve 31 is arranged between the third air duct 33 and the second air duct 22. In the prior art, there are various valves 31 to choose from, such as gate valves, ball valves or butterfly valves. There are multiple choices for the driving structure of the valve 31 in the prior art, which can be realized by those skilled in the art according to needs. Therefore, it will not be elaborated in this embodiment and is not shown in the drawings. An ultraviolet lamp 32 is arranged along the axial direction of the third air duct 33. An upper lamp slot 331 and a lower lamp slot 332 for fixing the ultraviolet lamp 32 are arranged up and down in the inner cavity of the third air duct 33. On one side of the upper lamp slot 331 facing the second air duct 22, there is an upper guard plate 3311. On the side of the upper lamp slot 331 facing away from the second air duct 22, there is an upper guard plate 3312 for restricting the ultraviolet lamp 32 from moving along the axial direction of the upper lamp slot 331. On one side of the lower lamp slot 332 facing the second air duct 22, there is a lower guard plate 3321. On the side of the lower lamp slot 332 facing away from the second air duct 22, there is a lower guard plate 3322 for restricting the ultraviolet lamp 32 from moving along the axial direction of the lower lamp slot 332. At the lower part of the upper lamp slot 331, there is an upper support plate 3313 for supporting the ultraviolet lamp 32. At the upper part of the lower lamp slot 332, there is a lower support plate 3323 for limiting the ultraviolet lamp 32. Through holes for the ultraviolet rays to pass through are arranged on both the upper support plate 3313 and the lower support plate 3323. The upper guard plate 3311 and the lower guard plate 3321 block the wind blowing from the second air duct 22 onto the ultraviolet lamp 32, playing a protective role. The upper guard plate 3312 and the lower guard plate 3322 play a role in limiting the ultraviolet lamp 32. The ultraviolet lamp 32 is inserted into the upper lamp slot 331 or the lower lamp slot 332, and then the upper guard plate 3312 or the lower guard plate is bolted. The upper guard plate 3312 or the lower guard plate 3322 is provided with holes for the wires of the ultraviolet lamp 32 to pass through. The upper support plate 3313 and the lower support plate 3323 are formed by opening the inner wall of the third air duct 33. To facilitate the replacement and maintenance of the ultraviolet lamp 32, a detachable mounting plate is arranged at the position corresponding to the ultraviolet lamp 32 on the outer side wall of the third air duct 33. For example, the mounting plate is bolted to the outer side wall of the third air duct 33. Disassembling the mounting plate is the upper lamp slot 331 or the lower lamp slot 332. The length of the mounting plate is longer than the length of the ultraviolet lamp 32. One end of the ultraviolet lamp 32 is provided with a mounting end electrically connected to the wire, which is convenient for taking and placing the ultraviolet lamp 32. When the ultraviolet lamp 32 needs to be replaced, the bolts are unscrewed, the mounting plate is disassembled, the mounting end is disconnected from the wire, the old ultraviolet lamp 32 is taken out, and the ultraviolet lamp 32 is repaired or replaced with a new one.

[0036] As Figure 7As shown, for the usage scenarios with higher requirements for the air in the car 6, a fourth air duct 44 is provided between the sterilization component and the air filtering component. At least one layer of filter screen is provided in the fourth air duct 44. The filter screen is fixed in the filter rack 42. Slots 43 are formed in the side wall of the fourth air duct 44 so that the filter rack 42 is inserted and sealed in the fourth air duct 44. The filter screen is fixed in the filter rack 42, and the filter rack 42 is inserted into the fourth air duct 44, making the installation and replacement more convenient. At least one layer of filter screen can filter the air more finely, achieving a better filtering effect. In a preferred embodiment, the fourth air duct 44 is provided with a frame groove for accommodating the filter frame. A plurality of filter racks 42 are fixedly distributed in parallel in the filter frame. Filter screens are fixed in the filter racks 42. A dust brushing component is provided between adjacent two filter racks 42. A dust brushing component is also provided on the front side of the filter rack 42 with a filter screen at the forefront along the wind direction. The dust brushing component includes a dust brushing plate rack. The dust brushing plate rack is designed to be hollow. The hollow area of the dust brushing plate rack allows the air flow to pass through. The dust brushing plate rack is arranged between adjacent two filter screens or on the front side of the filter screen at the forefront along the wind direction. Long strip-shaped brush plates are fixed on both sides of the dust brushing plate rack along the axial direction of the fourth air duct 44. The brush plates are arranged horizontally and perpendicular to the axial direction of the fourth air duct 44. Brush hairs in contact with the adjacent filter screen are provided on the side of the brush plate facing the adjacent filter screen. A toothed belt is fixed on the side wall of the dust brushing plate rack perpendicular to the direction of the fourth air duct 44. The dust brushing component further includes a dust brushing driving motor. The dust brushing driving motor can drive the dust brushing gear to rotate. The dust brushing gear meshes with the toothed belt, driving the toothed belt to move up and down, thereby driving the dust brushing plate rack to move up and down, so that the brush plates move up and down to brush off the dust particles on the filter screen. By providing the dust brushing component, the dust particles on the filter screen are brushed off, enabling the filter screen to maintain a large membrane flux for a long time, improving the filtering effect, reducing the wind resistance, and ensuring the air volume entering the elevator car 6. When the elevator is out of service, the dust brushing component is started to brush off the dust particles on the filter screen. A sealing cushion layer is provided between the dust brushing plate rack and the filter rack 42 to keep the two in interference fit and sealed. When the dust brushing component is not started, the air duct is kept sealed. For the dust particles brushed off from the filter screen, they can be regularly sucked by maintenance personnel by opening the corresponding position of the air duct with a vacuum cleaner or a dust collection bucket can be provided at the corresponding position in the air duct for centralized dust collection and cleaning.

[0037] The exhaust component includes an exhaust duct 51. The part of the exhaust duct 51 located inside the car 6 is fixed to the rear side wall of the car 6. A plurality of air holes 511 penetrating into the inner cavity of the exhaust duct 51 are formed on the surface of the exhaust duct 51.
