Description

[Detailed Description of the Invention] <Industrial Application Field> This invention relates to a temperature control device for an elevator.

<Prior Art> In the summer, the temperature inside an elevator car is quite high. In particular, elevators with transparent walls, such as observation elevators, are exposed to direct sunlight, resulting in a significant temperature rise.

On the other hand, in cold regions, the temperature inside elevator cars used in buildings drops considerably.

For this reason, in response to the rise in temperature inside elevator cars during the summer, fans were installed on the ceilings of elevator cars to blow air to the passengers to increase heat dissipation and prevent them from feeling stuffy.

However, it is clear that sufficient effects cannot be obtained with this fan alone. On the other hand, a heating device is required inside the elevator car used in cold regions.

For these reasons, some elevator cars are equipped with an air conditioner attached to the ceiling or side wall of the elevator car.

<Problems to be solved by the invention> The method of attaching a fan to an elevator car has only some effect on temperature rise inside the car. In a system in which an elevator car is equipped with an air conditioner, the temperature inside the car can be maintained at an appropriate temperature in response to a rise in temperature or a drop in temperature inside the car.

However, when an air conditioner is installed in a passenger car, a considerable amount of space is taken up by the air conditioner, so it is difficult to actually install the air conditioner in a small elevator due to the weight problem. Furthermore, when an air conditioner is installed, it is necessary to install a drainage device on the side of the car in the hoistway to dispose of the drain that occurs during operation, and it is also necessary to take measures to prevent vibration and noise from the compressor, etc. It won't happen. Furthermore, when starting up the compressor, a large current needs to flow, which requires the use of wide-diameter dedicated electric wires that are not used in normal elevators.

This idea was made to solve the problems with these conventional systems, and its purpose was to eliminate the need to install air conditioners in elevators.
To provide a temperature control device for an elevator that can realize temperature control and ventilation inside a car by simple means.

<Means for Solving the Problem> In order to solve the problems of the above-mentioned conventional method for temperature adjustment inside an elevator car, the elevator temperature adjustment device of this invention has a method for adjusting the temperature inside the elevator car. a stop detecting means for detecting that there is a call to the elevator; a call detecting means for detecting a call for the elevator; and a door opening means for opening the elevator door for a predetermined time when the call detecting means detects that there is no call. is provided.

<Function> In the elevator temperature adjustment device of this invention, when the stop detection means detects that the elevator is stopped at the landing, and the call detection means detects that there is no call for the elevator, the door opening means is activated and the elevator door is kept open for a predetermined period of time.

When the elevator is stopped at the landing, the doors of the elevator are opened, and air flows into the elevator car from the landing, which is cooled by the air conditioner in the summer and heated in the winter. For this purpose, the air inside the elevator car is ventilated, and air from the hall that is constantly cooled or heated is introduced into the elevator car, so the temperature inside the elevator car is adjusted. .

<Embodiment> Fig. 1 shows the configuration of the main parts of an embodiment of the elevator temperature control device of this invention, in which a stop confirmation normally open contact 1 and a stop detection means are connected between the power terminal P and the power terminal N. A first series connection circuit with the stop detection relay 10 is connected. A plurality of call detection normally closed contacts 2 and a call detection relay 2 as a call detection means
A second series connection circuit with 0 is formed, and this second
series connected circuits are connected in parallel to the first series connected circuit.

The normally closed contact 40b of the door open confirmation time relay 40, the normally open contact 10a of the stop detection relay 10, the normally open contact 20a of the call detection relay 20, and the third series connection circuit of the door open command relay 30 are connected in a second series connection. connected in parallel to the circuit.

Further, a fourth series connection circuit between the normally open contact 30a of the door open command relay 30 and the door open confirmation time relay 40, and the door open control relay 50 and the door open command relay 3 are provided.
A fifth series connection circuit with the normally open contact 30b of
It is connected in parallel to the third series connection circuit.

In step 1 of the flowchart in Figure 2, when the elevator stops at the landing and passengers get off,
The elevator doors are closed in step 2. The elevator is waiting at the hall with the door closed, with the stop confirmation normally open contact 1 in FIG. 1 closed and the stop detection relay 10 energized.

The presence or absence of a call for the elevator is confirmed by the call detection means in step 3 of FIG. When there is no call, all of the call detection normally closed contacts 2 in FIG. 1 are in a closed state. Therefore, the call detection relay 20 is energized and the normally open contact 20a is closed. Since the stop detection relay 10 is already energized, the normally open contact 10a is also closed.

Therefore, since the door open command relay 30 is energized, the normally open contacts 30a and 30b are closed. For this purpose, the door opening control relay 50 is energized, and the elevator door is opened in step 4 of FIG. When the normally open contact 30a closes, the door open confirmation time relay 40 is activated, and after a predetermined period of time, the door open confirmation time relay 40 is energized and the normally closed contact 4 is activated.
0b is opened and the door open command relay 30 is in a non-excited state.

Therefore, the normally open contacts 30a and 30b are opened, the door open control relay 50 and the door open confirmation time relay 40 are in a non-excited state, and the elevator door is closed from step 5 in FIG. 2 to step 2. . If there is still no call for the elevator in this state, the process proceeds to steps 3, 4, 5, and 2 in FIG. 2, and the elevator door is again opened for a predetermined period of time.

When a call is made to the elevator, the process proceeds from step 3 to step 2 in FIG. 2, the door is closed, and the elevator starts operating to the predetermined floor where the call occurred.

In this way, for elevators waiting in the hall with no calls, the door is repeatedly opened for a predetermined period of time until a call occurs, and the conditioned air is used to heat or cool the hall. is introduced into the elevator car. Therefore, temperature control and ventilation within the elevator car can be effectively performed.

FIG. 3 shows the configuration of the main parts of another embodiment of the elevator temperature control device of this invention, and this embodiment is different from the normally open contact 20a of the third series connection circuit in the embodiment shown in FIG. A normally closed contact 60 of an elevator car temperature detection device is inserted and connected between the door open command relay 30 and the door open command relay 30.

The elevator car is provided with a car temperature detection device (not shown), and when it is detected that the temperature inside the car is within a preset appropriate temperature range, the normally closed contact 60 is opened. It is configured as follows.

FIG. 4 is a flowchart showing the operation in another embodiment shown in FIG. Same as chat.

When it is confirmed in step 3 that there is no elevator call, the call detection relay 20 shown in FIG. 3 is energized and the normally open contact 20a is closed. Since the elevator is stopped at the hall, the stop detection relay 10 is energized and the normally open contact 10a is already closed.

However, when the car interior temperature detection device detects that the car interior temperature is within the appropriate temperature range, the normally closed contact 60 is in an open state and the door open command relay 30 is not energized. Therefore, the elevator door is not opened and the process proceeds from step 4 to step 2 in FIG.

On the other hand, when the car interior temperature detection device detects that the car interior temperature is outside the appropriate temperature range, the normally closed contact 60 is in a closed state and the door open command relay 30 is energized. Therefore, in this case, proceed through steps 4, 5, 6, and 2 in the flowchart of FIG.
The door is opened at the landing for a predetermined period of time.

In this way, in the embodiment shown in FIG. 3, conditioned air from the landing is introduced into the elevator car only when the temperature inside the elevator car is outside the optimum temperature range. Temperature adjustment and ventilation inside the car are effectively performed.

<Effects of the invention> As explained in detail above, according to this invention, the elevator is equipped with a simple stop detection means, a call detection means, and a door opening means, without installing an air conditioner or its accessories. It is possible to provide a temperature control device for an elevator that can always maintain the temperature inside the car at an appropriate temperature and also perform ventilation by introducing conditioned air from the landing into the car.
