  However, in Patent Document 1, there is a sway that lacks serviceability for passengers one step at a time, regardless of the situation where passengers who have boarded are placed only by 1 / f fluctuation blowing from the ceiling of the car.

  Moreover, in patent document 2, since it makes a passenger operate the switch provided in the side plate of the car, it was inconvenient for an unfamiliar user, and there was a case where a service full of a refreshing feeling could not be performed.

  Furthermore, Patent Document 3 gives an image of advertisement related to the use of a building, and it is difficult to say that the service is full of refreshing feeling.

  An object of the present invention is to realize a service that gives a refreshing feeling that varies depending on the situation of passengers who have entered the elevator car.

  In a preferred embodiment of the present invention, in an elevator car blower equipped with a cooler mounted in an elevator car and having a fan for sending cool air into the car, after the elevator car door is opened in response to a call, The operation period until the door is closed is divided into a plurality of periods, and air volume switching means for sending cool air into the car at different strengths for each period is provided.

  In a specific embodiment of the present invention, the plurality of periods include an elevator door opening stop period, an acceleration traveling period, and a deceleration period as different periods, respectively, and entering the car with different strengths in each period. Send cool breeze. Desirably, the wind is gradually weakened in these three periods, such as a strong wind during the elevator door stop period, a weak wind during the acceleration travel period, and a light wind during the deceleration period.

  In a preferred embodiment of the present invention, a diffuser is provided in a ventilation hole of a side plate of a car, and when a predetermined heat including a predetermined increase in temperature and / or humidity is sensed, rotation of the propeller of the diffuser and the diffusion plate are detected. By making the rotation of the air different, the diffused cross wind is sent.

  According to a preferred embodiment of the present invention, it is possible to realize a service that gives a refreshing feeling that varies depending on the situation of passengers who have entered the elevator car.

  Other objects and features of the present invention will become apparent in the embodiments described below.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is an image diagram showing an overall structure of a blower in an elevator car according to an embodiment of the present invention. The elevator of the present embodiment includes a blower hole (not shown) and a diffuser 2 that automatically diffuses cold air installed in the blower hole in a side plate portion of the car 1. In addition, a cooler 4 for sending cool air through the tube 3 and a ceiling fan 5 are mounted in the ventilation hole. Furthermore, in this embodiment, a liquid crystal display with sound 6 and a thermo switch 7 are provided.

  As usual, an instrument box 8 is mounted on the ceiling of the car 1, and a signal is transmitted to and from the control panel 10 via a tail cord 9 installed in the hoistway.

  The control panel 10 includes a microcomputer 11, which starts with the temperature detection determination of the thermoswitch 7 in the cooler 4, and according to the detection determination of various timers, the detection determination of the operation mode of the car, etc. 4, a cold air volume automatic switching command, an acoustic pattern and display pattern automatic switching command of the liquid crystal display 6 with built-in sound, and the like.

  2A is a side sectional view and FIG. 2B is a front view showing the structure of the diffuser 2 according to one embodiment of the present invention. Cooling air is automatically diffused by a propeller 23 attached to a rotating shaft 22 fixed to the bearing 21 and a diffuser plate 25 attached to a rotating shaft 24 having a different rotation. Convert to

  FIG. 3 is a processing flow by the microcomputer 11 according to an embodiment of the present invention.

  FIG. 4 is a time chart for explaining the relationship between the elevator speed curve and the diffusion cool breeze service according to an embodiment of the present invention.

  Hereinafter, the operation according to the embodiment of the present invention will be described with reference to the processing flow of FIG.

  First, in step 301 of FIG. 3, it is determined whether the thermo switch 7 has detected a predetermined high temperature. If the predetermined high temperature is not detected, the process is terminated. If the thermo switch 7 detects a predetermined high temperature, it is determined in step 302 whether the car 1 is opened in response to a call and is still stopped. If the door is not open, in step 303, the strong cool air from the cooler 4 is diffused by the diffuser 2, and a strong but cool air is sent to the passengers in the car 1 as a cross wind. As a result, passengers who have just entered the car 1 feel that they are saved by the coolness of the car 1 even during hot days.

  Eventually, when the door of the car 1 is closed and traveling is started, the determination in step 302 is changed to NO, and the process proceeds to step 404 to determine whether the car 1 is accelerating or traveling at high speed. The determination result is YES until the vehicle starts decelerating. During this time, in step 305, the cool air from the cooler 4 is diffused by the diffuser 2 and sent into the car 1. Therefore, as soon as the passenger gets in, the passengers who are saved by the coolness are healed by the crosswind of the slightly cold wind as the elevator starts.

  Next, when the car 1 approaches the stop floor and starts to decelerate, the determination in step 304 changes to NO, and in step 306, it is determined whether the car 1 is decelerating or the door is closed. Therefore, the weak cold air from the cooler 4 is diffused by the diffuser 2 and sent into the car 1 in step 307 until the car 1 stops at the target stop floor and opens the door. For this reason, passengers who have tasted cool enough can wait for the elevator doors to open under mild, diffuse weak winds.

  Finally, if the elevator door is opened and the determination in step 306 changes to NO (door open), air blowing is stopped in step 308.

  However, if there is a further call under hot conditions, strong cold air from the cooler 4 is diffused by the diffuser 2 in step 303 following steps 301 and 302 of the processing flow of FIG. A cool breeze is sent into the car 1 as a crosswind.

  In the above embodiment, the diffused cool breeze service is executed by detecting the high temperature by the thermo switch 7, but not only the high temperature but also a combination with a predetermined humidity or the summer / winter timer in the microcomputer 11. If the heat and humidity can be detected by a combination with the detection determination, the service may be executed accordingly.

  FIG. 5 shows a display screen with sound as an example of a service that can be added in another embodiment of the present invention.

  In FIG. 5, the liquid crystal display screen 6 is installed at a position that is easy to see from the passengers in the car 1, and displays a state in which the fireworks 61 are launched. At the same time, sound is emitted from the speakers 62 and 63 in accordance with the fireworks launch and flowering.

  This display and sound service is preferably executed during the aforementioned acceleration / high-speed traveling.

  For example, first, when summer is detected by the detection determination of the summer / winter timer in the microcomputer 11, and when a predetermined time is detected by the detection determination of the time zone timer, the sound pattern and the display pattern of the liquid crystal display 6 with built-in sound are changed. When the service of the car 1 is started (start-up / acceleration), fireworks are launched with sound, and while the car 1 is running, the sound and various fireworks are continuously displayed, and the service of the car 1 is completed (deceleration start or Stop) to end the fireworks display.

  In this embodiment, the summer / winter timer and the time zone timer in the microcomputer 11 have been described. However, the control panel 10 may be provided with a timer.

  Moreover, although the sound pattern and display pattern of the liquid crystal display 6 with built-in sound have been described in the fireworks launch mode, the display mode may be switched to a cool display mode such as surfing.

  Furthermore, although it demonstrated only with the crosswind from the side-plate part of a cage | basket | car, it can also combine with the ventilation from a ceiling.

It is an image figure which shows the whole structure of the air blower in the elevator car by one Example of this invention. It is (A) side surface sectional drawing and (B) front view which show the structure of the diffuser 2 by one Example of this invention. It is a processing flow by the microcomputer 11 by one Example of this invention.
