The air inlet 54 communicates with the car 51 through an air intake duct 56 formed between the inner wall of the car 51 and the lighting device 53. 55 communicates with the car 51 through an exhaust duct 57 formed between the inner wall of the car 51 and the lighting device 53, and the intake duct 56 and the exhaust duct 57 are partitioned.

Reference numeral 60 denotes a ventilation case provided on the ceiling 52, in which an intake chamber 61 communicating with the intake port 54 and an exhaust chamber 62 communicating with the exhaust port 55 are formed. In FIG. 13A, exhaust chambers 62 are disposed at both left and right ends of the intake chamber 61, and a shutter 63 that can be opened and closed is provided between the chambers.
The ventilation case 60 has a silencer 64 affixed to its inner surface, a labyrinth-like silencer slit 65 that communicates the intake chamber 61 with the outside air, and a labyrinth-like silencer fine that communicates the exhaust chamber 62 with the outside air. A gap 66 is provided.

  Reference numeral 70 denotes a blower provided with a suction port 71 and a discharge port 72, respectively, and the blower 70 is connected to the suction port 54. doing.

Next, the operation of the apparatus will be described.
As shown in FIG. 13, when the shutter 63 is in an open state, the air (arrow) in the car 51 is driven by the operation of the blower 70, so that the exhaust duct 57 → the exhaust port 55 → the exhaust chamber 62 → the opening of the shutter 63 → It flows into the suction port 71 of the blower 70 through the intake chamber 61.
Further, the air discharged from the discharge port 72 of the blower 70 circulates and is sent into the car 51 through the intake port 54 and the intake duct 56.
In this ventilation, there is almost no ventilation ventilation performed through the muffling slit portions 65 and 66.

Next, the case where the shutter 63 is opened by an appropriate amount and the passing air amount is reduced will be described with reference to FIG.
As described above, the air (arrow) in the car 51 flows into the suction port 71 of the blower 70 through the exhaust duct 57 → the exhaust port 55 → the exhaust chamber 62 → the opening of the shutter 63 → the intake chamber 61. Since the opening amount of the shutter 63 is small, a part of the air is exhausted to the outside from the exhaust chamber 62 through the silencing slit 66.
Further, outside air flows into the intake chamber 61 from the muffling slit portion 65, is mixed with air from the opening of the shutter 63, flows into the suction port 71, and flows from the discharge port 72 to the intake port 54 and the intake duct 56. Through the car 51. Thereby, some air is ventilated.

  In this way, the inflow amount of the outside air can be adjusted by adjusting the opening degree of the shutter 63 and increasing / decreasing the aperture.

It is AA sectional drawing and BB sectional drawing of FIG. It is conventional operation explanatory drawing corresponding to FIG.

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a view of a ceiling part of an elevator car as seen from inside the car, FIG. 2 is a schematic plan view of the car, FIG. 3 is a partial sectional view of the car ceiling part, and FIG.
In the figure, 1 is a ceiling of the car 2, and 3 is a side wall of the car 2. Reference numeral 10 denotes a disk-shaped air conditioner having a housing 9 that protrudes into the car 2 in a ring shape, and includes a motor 11 and a rotating shaft 12 of the motor at the center. The rotating shaft 12 is provided with a plurality of fans 13 that rotate in the housing 9, and the end portions 14 of these fans 13 are extended downward. An illuminating device 4 is installed inside the cage 2 at the center of the housing 9.

A plurality of fixed plates 16 are provided on the inner peripheral side 15 facing the end portion 14 of the fan 13, and a space between the fixed plates 16 serves as an air inlet 17. Further, each suction port 17 is provided with a movable shielding plate 18, and the suction port 17 is opened and closed by sliding the shielding plate 18.
Reference numeral 20 denotes an air blowing port formed on the outer peripheral side 21 facing the end portion 14 of the fan 13, and includes a filter 22 and a louver 23. In FIG. 1, the filter 22, the louver 23, and the illumination device 4 are not shown. Reference numeral 30 denotes a communication port opened in a portion of the ceiling 1 facing the end portion 14 of the fan 13, and 31 denotes a connection fitting that connects the center side (motor 11 side) and the outer peripheral side of the ceiling 1.

  Next, the operation of the present embodiment will be described. When the shielding plate 18 is in a position overlapping the fixed plate 16, the suction port 17 is open. When the fan 13 is rotated in this state, the air in the car 2 flows from the suction port 17 to the blower port 20 as shown by an arrow a in FIGS. Go down along 3. Thereby, ventilation is made over the entire circumference in the car 2. Further, as shown by the arrow b, since a part of the outside air flows through the communication port 30 to the blower port 20, the operation in the circulation mode including partial ventilation is performed.

FIG. 4B shows a case where the shielding plate 18 is closed. In this case, since the suction port 17 is closed, the air flow is only the flow indicated by the arrow b, and the operation in the ventilation mode is performed.
The shielding plate 18 can be slid from a position overlapping the fixing plate 16 to a position where the suction port 17 is closed. The sliding operation of the shielding plate 18 may be controlled by using a motor or the like. It can also be manually operated from within 2.

  Thus, according to the present embodiment, the air ventilation mode and the circulation mode can be switched only by opening and closing the shielding plate 18. Moreover, since the air conditioner 10 is a disk-shaped thin shape, the height of the cage | basket | car 2 can be restrained compared with the past.

In addition, a filter 33 can be provided on the suction port 17 side, and a wire mesh or the like may be provided at the suction port 17 so that passengers or the like do not touch the end portion 14 of the fan 13 from within the car 2. In addition, what is necessary is just to determine arbitrarily the number and magnitude | size of the fixing plate 16, the inlet port 17, the shielding board 18, the ventilation port 20, and the ventilation port 30. FIG.

  Further, in the above embodiment, the motor 11 is installed on the upper surface side of the ceiling 1 of the car 2, but it can also be installed in the car 2, that is, on the lighting device 4 side. In this way, the number of parts on the upper surface of the car 2 can be reduced, so that maintenance work and the like on the car can be easily performed.

Next, another embodiment of the present invention will be described with reference to FIGS. 6 is a partial plan view of the car ceiling, and FIG. 7 is a view corresponding to FIG.
In the figure, reference numeral 40 denotes an air conditioner, which has a configuration in which air is sucked into the air conditioner 40 from one communication port 30a and cool air (or warm air) from the air conditioner 40 is sent into the car 2 from the other communication port 30b.

The communication port 30a side at this time has a configuration in which the air blowing port 20 is closed by a shielding plate 41, as shown in FIG. For this reason, as shown by an arrow c, air is sent from the suction port 17 to the air conditioner 40 through the communication port 30a.
On the communication port 30b side, the suction port 17 is closed by the shielding plate 18, as shown in FIG. 4B. For this reason, as shown by the arrow b, the cool air (or warm air) from the air conditioner 40 is sent from the communication port 30 (30b) through the blower port 20 into the car 2.
With this configuration, the number of fans in the air conditioner indoor unit can be reduced, so that the cost can be reduced and the space on the car can be saved.

In order to send the cool air (or warm air) from the air conditioner 40 uniformly into the car 2, the cool air (or warm air) may be sent to the plurality of communication ports 30.
The communication port 30 that is not connected to the air conditioner 40 is provided with a shield plate that can be opened and closed. When ventilation is performed without using the air conditioner 40, the shield plate is opened. Similarly to the above-described embodiment, as shown in FIG. 5, a soundproof cover 32 may be provided at the communication port 30 not connected to the air conditioner 40, or a filter 33 may be provided at the suction port 17.

Next, the example which provides the apparatus which detects the temperature inside and outside the cage | basket | car 2, and controls the air conditioner 10 by this temperature is demonstrated.
FIG. 8 is a flowchart showing an example of the embodiment of the present invention. Here, the air conditioner 10 is inverter-controlled, and the rotation speed of the fan 13 is variable. The shielding plate 18 is controlled by motor driving.

  First, in step S1, the magnitude of the optimum temperature determined in advance and the temperature in the car are compared. If the temperature inside the car is below the optimum temperature, step S2 is executed. In step S2, the air conditioner 10 is controlled so that the air volume is reduced to an amount necessary for the minimum ventilation volume and the ventilation ratio is maximized. Thereby, when the temperature in the car is low, the air volume is lowered, and the wind hitting the passenger in the car is minimized.

Next, when it is determined in step S1 that the temperature inside the car is higher than the optimum temperature, step S3 is executed. In this step S3, the size of the temperature inside the car is compared with the temperature inside the hoistway (outside the car). If it is determined that the temperature inside the car is equal to or higher than the temperature inside the hoistway, step S4 is executed.
In step S4, the air conditioner 10 is controlled so that the air volume is proportional to the difference between the car temperature and the optimum temperature, and the ventilation ratio is proportional to the difference between the hoistway temperature and the car temperature. Thereby, it becomes the air volume and ventilation ratio according to temperature.

Next, when it is determined in step S3 that the temperature in the car is lower than the temperature in the hoistway, step S5 is executed.
In step S5, the air conditioner 10 is controlled so that the air volume is proportional to the difference between the car temperature and the optimum temperature, and the ventilation ratio is minimized. Thereby, when the temperature in the car is high, the amount of warm air in the hoistway entering the car is suppressed.

Next, FIG. 9 is a flowchart showing another example of the embodiment of the present invention. Here, the air conditioner 10 is assumed to be relatively simple capable of switching the air volume between large and small.
First, in step S10, the predetermined optimum temperature is compared with the magnitude of the temperature in the car. If the car temperature is below the optimum temperature, step S11 is executed. In this step S11, the size of the temperature inside the car is compared with the temperature inside the hoistway (outside the car). If it is determined that the temperature inside the car is equal to or higher than the temperature inside the hoistway, step S12 is executed.

In step S12, both the air volume and the ventilation ratio of the air conditioner 10 are minimized. Thus, when the temperature in the car is low, the amount of cool air in the hoistway entering the car is minimized, and the wind hitting the passengers in the car is minimized.
As shown in FIG. 4A, since the communication port 30 is always open, even if the ventilation ratio is minimized, a certain amount of outside air enters the hoistway, but is blocked by the communication port 30. If a plate is provided, the ventilation rate can be made zero.

Next, when it is determined in step S11 that the temperature in the car is lower than the temperature in the hoistway, step S13 is executed.
In step S13, the air volume of the air conditioner 10 is minimum and the ventilation ratio is maximum. Thus, when the temperature in the car is low, the ratio of warm air in the hoistway entering the car is maximized, and the wind hitting the passengers in the car is minimized.

If it is determined in step S10 that the temperature inside the car is higher than the optimum temperature, step S14 is executed. In this step S14, the size of the temperature inside the car is compared with the temperature inside the hoistway (outside the car). When the car temperature is equal to or higher than the hoistway temperature, step S15 is executed.
In step S15, the air volume and the ventilation ratio of the air conditioner 10 are both maximized. Thereby, when the temperature in the car is high, the amount of cool air in the hoistway entering the car is maximized, and the wind hitting the passengers in the car is also maximized.

If it is determined in step S14 that the temperature in the car is lower than the temperature in the hoistway, step S16 is executed.
In step S16, the air volume of the air conditioner 10 is maximized and the ventilation ratio is minimized. Thus, when the temperature in the car is high, the amount of warm air in the hoistway entering the car is minimized, and the wind hitting the passengers in the car is maximized.
Further, as described in step S12, the ventilation ratio can also be set to zero in step S16. Further, in step S5 in the embodiment of FIG. 8, the ventilation ratio may be set to zero.

  Next, FIG. 10 is a flowchart showing another example of the embodiment of the present invention. Here, the air conditioner 10 is assumed to be relatively simple so that the air volume can be switched between large and small as described above. The optimal temperature is not a single temperature. A width between the first temperature and the second temperature (first temperature> second temperature) is provided.

  First, in step S20, the air volume and the ventilation ratio are set to arbitrary default values. Next, in step S21, the temperature in the car is compared with the first temperature. If the temperature inside the car is equal to or lower than the first temperature, step S22 is executed. In step S22, the temperature in the car is compared with the second temperature. If the temperature inside the car is equal to or lower than the second temperature, step S23 is executed. In step S23, the temperature in the car is compared with the temperature in the hoistway (outside the car). If the car temperature is equal to or higher than the hoistway temperature, step S24 is executed.

In step S24, both the air volume and the ventilation ratio of the air conditioner 10 are minimized. Thus, when the temperature in the car is low, the amount of cool air in the hoistway entering the car is minimized, and the wind hitting the passengers in the car is minimized.
Next, when it is determined in step S23 that the temperature in the car is lower than the temperature in the hoistway, step S25 is executed.
In step S25, the air volume of the air conditioner 10 is minimum and the ventilation ratio is maximum. Thus, when the temperature in the car is low, the ratio of warm air in the hoistway entering the car is maximized, and the wind hitting the passengers in the car is minimized.

  If it is determined in step S22 that the temperature inside the car is higher than the second temperature, step S26 is executed. In step S26, the temperature in the car is not higher than the first temperature and higher than the second temperature, so the current state is maintained, that is, the state of the default value in step S20 is maintained.

If it is determined in step S21 that the temperature inside the car is higher than the first temperature, step S27 is executed. In this step S27, the size of the temperature inside the car is compared with the temperature inside the hoistway (outside the car). If the car temperature is equal to or higher than the hoistway temperature, step S28 is executed.
In step S28, the air volume and the ventilation ratio of the air conditioner 10 are both maximized. Thereby, when the temperature in the car is high, the amount of cool air in the hoistway entering the car is maximized, and the wind hitting the passengers in the car is also maximized.

If it is determined in step S27 that the temperature in the car is lower than the temperature in the hoistway, step S29 is executed.
In step S29, the air volume of the air conditioner 10 is maximized and the ventilation ratio is minimized. Thus, when the temperature in the car is high, the amount of warm air in the hoistway entering the car is minimized, and the wind hitting the passengers in the car is maximized.

In the embodiment of FIG. 10 as well, the ventilation ratio may be zero instead of minimizing the ventilation ratio as in the case of FIG.
Further, in the embodiment of FIG. 9 and FIG. 10, the rotation speed of the fan 13 of the air conditioner 10 is variable, and according to the difference between the car internal temperature and the optimum temperature, or the difference between the car internal temperature and the car external temperature, The air volume and ventilation ratio may be controlled.

FIG. 11 is a diagram showing another example of the embodiment of the present invention, which is a table for determining the air volume and the ventilation ratio based on the difference between the temperature and humidity inside the car and the temperature inside the car and the temperature inside the hoistway (outside the car). is there. In this embodiment, the air conditioner 10 is inverter-controlled, and the rotation speed of the fan 13 is variable. In each figure, the vertical is the car humidity and the horizontal is the car temperature, the upper number in each humidity column represents the air volume, and the lower number represents the ventilation ratio.
FIG. 11A is a table in the case where there is no difference between the temperature in the car and the temperature in the hoistway, FIG. 11B is a table in which the temperature in the hoistway is 3 degrees higher than in the car, and FIG. ) Is a table when the temperature in the car is 3 degrees higher than in the hoistway. In this embodiment, the case where there is no temperature difference (FIG. 11A) and the case where the inside of the hoistway is three degrees higher (FIG. 11B) are the same.

Numbers such as 2, 8 in the table indicate ratios where the maximum value is 10 and the minimum value is 0. Accordingly, 2 is a ratio of 20%.
The table in FIG. 11 is an example, and is changed depending on the situation at the site or the request of the customer.

In each of the above embodiments, a device for detecting the temperature and humidity inside and outside the car is provided, but another odor sensor is provided to detect the odor inside and outside the car, and when the odor inside the car is large, the ventilation ratio is increased. When the odor outside the car is large, the ventilation ratio can be lowered or not ventilated (only circulation of air in the car). Further, a dust sensor can be provided to perform the same control as in the case of the odor sensor.
Furthermore, a device for detecting the number of passengers in the car can be provided to increase the air volume when there are many passengers in the car.

  In the embodiment shown in FIG. 6, an air conditioner is provided, but an air purifier or a dehumidifier may be provided. Further, a smoke sensor may be provided to detect smoke inside and outside the car, increasing the ventilation ratio when there is a lot of smoke in the car, and not venting when there is a lot of smoke outside the car.
