Abstract

PURPOSE:To enable a passenger to understand the case to be a drain discharging operation even if the passenger is left on a drain discharging floor by providing an indicating means for indicating that the drain discharging operation is under way in an elevator at the time of a through running operation to a drain discharging floor. CONSTITUTION:When a drain discharging floor is set as a non-stop floor, if a drain quantity detecting means8 detects that a drain quantity becomes above a defined value, a drain discharging operation means 2 carries out the through running operation of an elevator cage to a drain discharging floor and, as the cage arrives at the drain discharging floor, drain discharge water is drained by the action of a drain discharge valve control device 9. During this discharging operation, on the assumption that there is a passenger left in the elevator cage, it is announced or indicated that a drain discharging operation of a cooler is under way by an indicating means 10 in the cage to remove the sense of unease of a passenger left in the cage.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an elevator control device, and particularly to an elevator control device characterized by drain discharge operation control of an elevator equipped with a cooler.

(Prior Art) In recent years, as demand for elevators has increased, elevator system specifications required by users have become more diverse and sophisticated. Under these circumstances, today, elevators in hotels and department stores are equipped with coolers above the cars, which are used to alleviate the high temperature and humidity inside the cars, especially during the summer season.

In an elevator system where such a cooler is installed, it is necessary to discharge the drain just like a household cooler, but generally in the case of an elevator cooler, this drain drainage is The drain is discharged to the hoistway pit on the lowest floor as the drain discharge floor. For this purpose, a float switch is installed in the drain tank, and when the water reaches about 80% of its full capacity, a signal is input into the elevator control system, and the car runs straight to the bottom floor while responding to calls in the same direction. , When the lowest floor, which is the drain discharge floor, is reached, the drain water is discharged from the drain tank.

(Problem to be solved by the invention) However, in current building management, in order to restrict the use of elevators on each floor, certain floors are restricted from being used by elevators according to arbitrarily set times or the manager's judgment. In order to prevent people from using the elevator, many elevator systems are equipped with non-stop operation control that disables car call and hall call registration using a 24-hour timer or switch. For example, in cases such as department stores, the basement floor is often used as a parking lot, but especially in such building systems, there are many cases where the basement floor is a non-stop floor after a certain time.

If the underground floor, that is, the lowest floor, is the non-stop floor, if a passenger happens to board the car from the upper floor in order to go to the lowest floor, the drain volume of the cooler may be 80% full. As described above, if the car is driving directly to the bottom floor while responding to calls in the same direction, the car will be driven to the bottom floor even though the car call for the bottom floor cannot be registered, so the passenger will simply Thinking it was a problem with the call button light, I stayed on board until I reached the bottom floor.

However, after arriving at the bottom floor, the operation of the car is restricted for a while due to the drain discharge operation, and since it is a non-stop floor, the elevator door opening/closing button is also disabled, so passengers are unable to understand the situation. Without knowing what to do, you will be temporarily stuck in a trap, which will make you feel anxious. In such a situation, even if a passenger operates a car call button on another floor, the car call response operation is stopped while the drain is being discharged, which creates a problem in which passengers feel uneasy. Ta.

This invention was made in view of such conventional problems.In an elevator equipped with a cooler, when the amount of water discharged in the drain tank exceeds a predetermined value and the operation starts straight to the drain discharge floor, the current drain is stopped. It is displayed so that passengers can see that the drain is in operation, and after the drain is discharged, it is forced to run to the nearest upper or lower floor of the drain discharge floor, and the floor is set so that it does not stop during the drain discharge operation. To provide an elevator control device that does not make passengers feel anxious even if an elevator car stops at a drain discharge floor and passengers are left behind in the car.

[Structure of the Invention] (Means for Solving the Problems) The elevator control device of the present invention includes a drain amount detection means for detecting that the drain amount of the cooler has exceeded a predetermined value, and an output of the drain amount detection means. a drain discharge operation control means for operating the drain directly to a pre-designated drain discharge floor in response to a request, a drain discharge control means for discharging the drain when the elevator stops at the drain discharge floor, and a drain discharge operation control means for discharging the drain when the elevator stops at the drain discharge floor; and when the non-stop floor setting means sets the drain discharge floor to the non-stop floor, the drain discharge operation control means operates the elevator directly to the drain discharge floor and drains the drain. Forced forwarding operation means for forcedly driving the drain to an upper or lower floor nearest to the drain discharge floor after draining, and a display means for displaying in the elevator that the drain is being discharged when driving directly to the drain discharge floor. It is equipped with the following.

(Function) In the elevator control device of the present invention, when the drain discharge floor is set to a non-stop floor and the drain amount detection means detects that the drain amount has exceeded a predetermined value, the drain discharge operation means is activated. The elevator car is operated directly to the drain discharge floor, and upon reaching the drain discharge floor, the drain wastewater is discharged.

During this draining operation, assuming that there are passengers left in the elevator car, a display means in the car announces or displays that the cooler drain is currently being drained; Avoid causing anxiety to stranded passengers.

Furthermore, after drain discharge is completed, the elevator car is forcibly redirected to the upper or lower floor closest to the drain discharged acid, and the passengers who were left behind in the elevator car are rescued.

(Example) Hereinafter, embodiments of the present invention will be explained in detail based on the drawings.

FIG. 1 shows an embodiment of the present invention. Reference numeral 1 denotes a cooler operation system section. The non-stop operation control section 3 does not respond to calls or hall calls and prohibits door opening/closing.

The cooler operation control section 2 includes an operation system section 21, a drain discharge time control section 22, a second floor automatic operation control section 23, and a car position detection control section 24. Note that the second floor automatic operation control unit 23 is a control unit that forcibly operates the car up to the second floor, but this is because the drain discharge acid is set to the first floor, which is the lowest floor.
When the drain acid is discharged from the basement or the roof floor, the second floor automatic operation control section is used as the automatic operation control section for the upper or lower floor closest to the drain discharge acid.

4 is an input buffer for signals input to the cooler operation control section 2, and 5 is an output buffer for signals output from the cooler operation control section 2. Further, 6 is an input buffer for signals input to the non-stop floor operation control section 3.

Furthermore, 7 is a pulse generator for detecting the position of the elevator car, 8 is a drain amount detection float switch that operates when the cooler drain amount reaches approximately 80% or more of full water and gives a drain discharge command signal, and 9 is a drain amount detection float switch. A drain discharge valve control device for the cooler body, 10 an indicator light in the car for indicating that the drain discharge operation is in progress; 11;
is a bottom stop sweetch.

The operation of the elevator control device having the above configuration will be explained next.

During cooler operation, the drain amount detection float switch 8 provided under the car is turned on, and when the input is input to the cooler operation control section 2 through the input buffer 4 (step S1.S
2) The operation system unit 21 in the cooler operation control unit 2 operates the car directly to the lowest floor for drain discharge while responding to calls for the down direction (steps S3 to S6).

Here, whether or not the elevator car has arrived at the lowest floor is determined by counting the pulse generator turf signal and using the lowest floor position data set in advance in the car position detection control section 24 in the cooler operation control section 2. It is determined that they have reached the bottom floor at the same time.

After stopping at the lowest floor, a drain discharge command signal is output from the cooler operation control unit 2 to the drain discharge valve control device 9 via the output buffer 5, and drain water is discharged from the drain tank of the cooler to the hoistway pit of the elevator. (Step S7).

This drain discharge control is set in advance as a discharge time in the discharge time control section 22, and the time is counted by a counter therein from the time the drain reaches the bottom floor, and the drain is discharged for the set discharge time. (Step S8
).

Note that from the time the float switch 8 is turned on until the discharge control at the lowest floor is completed, an output signal is output from the operation system section 21 of the cooler operation control section 2 via the output buffer 5, and the An in-car indicator light 10 is lit to announce to passengers that the car is in operation for draining the cooler.

During the return operation to the lowest floor, if the lowest floor non-stop switch 11 provided on the operation panel etc. is input to the non-stop operation control section 3 via the input buffer 6, this non-stop operation control is performed. 3 to the second floor automatic operation control section 23 in the cooler operation control section 2 (step S9), and after completion of drain discharge on the lowest floor, a car call is sent to the second floor, which is the floor 11 floors above. Automatic registration is performed (step 510), and forced forwarding operation to the second floor is performed (step 511).

If the cooler drain tank does not reach 80% or more in step S2, or if the lowest floor for drain discharge is not set as a non-stop floor in step S9, the elevator is operated normally (step 512).

In this way, in an elevator with a cooler,
When the cooler drain is full and the car is driven straight to the bottom floor to drain the drain, passengers are left stranded on the bottom floor because the bottom floor is designated as a non-stop floor. In order to prevent people from feeling anxious because the door will not open on the lowest floor where the car has stopped and the car cannot call to another floor, a message indicating that the drain is being discharged will be displayed inside the car. After the drain is discharged, the car is forcibly redirected to the nearest floor and the passengers are rescued.

[Effects of the Invention] As described above, according to the present invention, when the drain discharge operation is designated as a non-stop floor, when driving directly to the drain discharge operation, the car white display means indicates that the drain discharge operation is being performed. In addition, in order to forcibly send the car to the nearest floor after the drain discharge is completed, even if a passenger is left behind during drain discharge operation, which is a non-stop floor, the display means indicates that the drain discharge operation will continue. Passengers can understand that this is the case, and after the drain has been discharged, the vehicle is automatically redirected to the nearest floor, allowing passengers who are left behind to escape on that floor. This can be done without causing any great anxiety to the passengers who are left behind.
