Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of car water removal, in particular to a passenger elevator car structure. Background Art

[0019] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.
[0020] like Figure 1-6 As shown, a passenger elevator car structure includes a frame 1 and a car 2, the car 2 is arranged on the upper end surface of the frame 1, electric heating plates 3 are evenly arranged inside the frame 1, water immersion sensors 4 are evenly arranged on the electric heating plates 3, mounting holes for mounting the water immersion sensors 4 are provided at the bottom of the car 2, a blower 5 is provided outside the car 2, ventilation slots 6 are provided on the side walls of the car 2, an air outlet of the blower 5 blows toward the bottom of the car 2 through the ventilation slots 6, a heat dissipation fan 7 is provided at the lower part of the frame 1, a ventilation duct 8 is provided below the heat dissipation fan 7, the air outlet of the ventilation duct 8 is through-connected with the air inlet of the blower 5, and the heat dissipation fan 7 is through-connected with the inside of the ventilation duct 8 through an air supply pipe 9.
[0021] The frame 1 is used to support the car 2. The electric heating plate 3 located at the bottom of the car 2 is used to heat the bottom of the car 2. The electric heating plate 3 can heat the bottom of the car 2 to 45°C with an error of ±2°C. By heating the bottom of the car 2, the evaporation rate of water stains can be accelerated. The water immersion sensor 4 is used to detect whether there is water stain on the bottom of the car 2, such as rainwater on shoes or rainwater on an umbrella flowing to the bottom of the car 2. When rainwater just covers the water immersion sensor 4, or flows to the water immersion sensor 4 through flow, the electric heating plate 3 connected to the water immersion sensor 4 starts to start, and the electric heating plate 3 heats the bottom of the car 2 in the area directly above to increase the temperature of the bottom of the car 2, thereby accelerating the evaporation rate of water stains. When any electric heating plate 3 is working, it will drive the fan 5 to work. The fan 5 adopts a cross-flow fan with oblong blades. The cylindrical shape is used to increase the width of the air outlet. When the electric heating plate 3 is working, it will generate more heat. At this time, the electric heating plate 3 itself needs to be cooled by the heat dissipation fan 7. The heat dissipation fan increases the surface air speed of the electric heating plate 3 to reduce the temperature of the electric heating plate 3. After the air is heated by the electric heating plate 3, it is transported to the inside of the blower 5 through the air duct 9 and the ventilation duct 8. The blower 5 broadcasts part of the heated air to the bottom of the car 2. At the same time, accompanied by the heating effect of the car 2 itself, the broadcast wind temperature can be higher, which is warm wind, which is beneficial to accelerate the evaporation of water stains at the bottom of the car 2, thereby keeping the floor of the car 2 dry. When the water immersion sensor 4 cannot detect the presence of water, the electric heating plate 3 stops working. Under the action of the residual temperature of the electric heating plate 3 and the bottom of the car 2, the water stains that may still remain are continuously heated until they are completely evaporated.
[0022] When all the water sensors 4 at the bottom of the car 2 cannot detect the presence of water stains, all the electric heating plates 3 stop working, and the air blower 5 also stops working.
[0023] Furthermore, a sealing gasket 10 is provided on the outer surface of the water immersion sensor 4, and the outer surface of the sealing gasket 10 is sealed and connected to the inner surface of the mounting hole at the bottom of the car 2. The sealing gasket 10 is a rubber gasket, which can prevent water stains from entering the heating plate through the mounting hole, and can also prevent extrusion damage between the water immersion sensor 4 and the mounting hole.
[0024] Furthermore, the ventilation slots 6 are arranged to be tilted downward so that the wind blown by the blower 5 can be blown to the bottom of the car 2 as much as possible, reducing the waste of hot air resources, and when the cleaning staff cleans the bottom of the car 2, the water on the mop can also trigger the water immersion sensor 4, so that the electric heating plate 3 and the blower 5 are turned on at the same time. The tilted ventilation slots 6 and the blower 5 continuously output air and cooperate with each other, which can prevent water stains on the mop and the floor of the car 2 from entering the blower 5 through the ventilation slots 6, which is beneficial to protecting the blower 5.
[0025] Furthermore, wind guide plates 11 are symmetrically arranged inside the ventilation slot 6, and the lower ends of the wind guide plates 11 are inclined toward the side walls of the car 2. Since the wind speed at both sides of the bottom of the car 2 is relatively small and the temperature is relatively low, the wind guide plates 11 can be set to increase the wind volume blowing to both sides of the bottom of the car 2. Correspondingly, the wind temperature will also increase accordingly, so that the middle and side parts of the bottom of the car 2 can complete the evaporation of water stains in approximately equal time, thereby improving the utilization rate of hot air.
[0026] Furthermore, a mounting frame 12 is provided at the bottom of the frame 1, and the electric heating plate 3 is arranged on the mounting frame 12. Since nine electric heating plates 3 are used in the embodiment, the mounting frame 12 is in a tic-tac-toe shape. The corresponding form of the mounting frame 12 is reasonably selected according to the number of electric heating plates 3. A disc is provided at the cross intersection on the mounting frame 12, which can better support the four electric heating plates 3 in contact.
[0027] The device can detect whether there is water at a fixed position at the bottom of the car 2 through a water immersion sensor 4. When water exists, the bottom of the car 2 is heated by the electric heating plate 3. The evaporation rate of the water stains is increased by increasing the temperature of the bottom of the car 2. The water can be blown away by the fan 5 to increase the contact area between the water stains and the bottom of the car 2, further improving the drying efficiency of the water stains. The water stains can be removed in real time with high removal efficiency, and will not affect the normal boarding and disembarking of passengers in the elevator, thus achieving good use effect.
