Embodiment 1 FIG.
1 to 6 relate to Embodiment 1 of the present invention. FIG. 1 is a front view showing an overall configuration of an elevator floor heating device, FIG. 2 is a plan view of a car, and FIG. 3 is a front view of the car. 4 is a plan view showing details of the floor heating panel and the indirect heat recovery heat exchanger, FIG. 5 is a front view showing details of the floor heating panel and the warm air dispersion panel, and FIG. 6 shows details of the warm air dispersion panel. FIG.
In the figure, reference numeral 1 denotes a hoistway provided vertically in a building in which an elevator is installed. A car 2 is disposed in the hoistway 1 so as to be able to move up and down. A car door 3 is provided in front of the car 2 so that it can be opened and closed. When the car 2 stops on the floor, a landing door 4 can be opened and closed at a position facing the car door 3. Is provided.
Guide rollers 5 for guiding the car 2 are attached to both sides of the car 2 by engaging a pair of guide rails (not shown) standing in the hoistway 1. ing. One end of a main rope 6 is connected to the upper portion of the car 2. The main rope 6 is wound around a pulley 7 and the other end is connected to a counterweight (not shown).
A stove 8 is installed in the residential area of the building, and a flue 9 for exhausting heat exhausted from the stove 8 to the outside of the building is provided in the hoistway 1 and the interior of the building. Between the living areas, it is installed vertically next to each other. And between the flue 9 and the hoistway 1 and between the flue 9 and the living area, heat in the flue 9 is transferred into the hoistway 1 or the living area. A heat radiating panel 10 for radiating heat is provided, and the heat radiating panel 10 provided between the flue 9 and the hoistway 1 is exposed into the hoistway 1. The heat radiating panel 10 is made of a material such as stone.

A heat exchanger 11a for direct heat recovery is installed on the wall of the hoistway 1 at the bottom of the hoistway 9 side. As the direct heat recovery heat exchanger 11a, for example, a paper specification heat exchanger is used.
The floor portion of the car 2 is provided with a floor heating panel 12 having a plurality of warm air passage holes 12a. The floor heating panel 12 and the direct heat recovery heat exchanger 11a are communicated with each other by a telescopic duct 13 connected to the floor heating panel 12 from below the car 2, and the direct heat recovery. Warm air supplied from the heat exchanger 11 a passes through the duct 13 and passes through the warm air passage hole 12 a of the floor heating panel 12.
A floor warm air dispersion panel 14 is mounted on the floor heating panel 12, and a number of warm air dispersion holes 15 are formed in the floor warm air dispersion panel 14 to form an outlet 16. . A ceiling warm air dispersion panel 17 is attached to the ceiling portion of the car 2, and a number of warm air dispersion holes 15 are formed in the ceiling warm air dispersion panel 17 to form discharge ports 18. Yes.

An indirect heat recovery heat exchanger 11b and a circulation pump 19 are attached to the lower portion of one side wall outside the car 2. This indirect heat recovery heat exchanger 11b uses, for example, a plate heat exchanger. The interior of the floor heating panel 12 is hollow and filled with a heat medium 20 (brine). A plurality of fins 12 b that rectify the heat medium 20 that circulates in the floor heating panel 12 are provided at positions adjacent to the edge of the warm air passage hole 12 a provided in the floor heating panel 12. In particular, the fins 12b are provided so as to bisect the interior of the floor heating panel 12 while leaving a gap through which the heat medium 20 passes at substantially the center. Further, the circulation pump 19 receives the heat medium 20 that has returned through circulation in the floor heating panel 12 instead of the side that sends out the heat medium 20 from the indirect heat recovery heat exchanger 11b. On the side. This is because the circulation of the heat medium 20 is mainly natural circulation as will be described later.
The top of the hoistway 1 is provided with a vent 22 such as a louver for discharging the air in the hoistway 1 to the attic 21 above the hoistway 1. Is provided with a ventilation port 22 for discharging the air in the attic 21 to the outside of the building.

The exhaust heat from the stove 8 is exhausted to the outside of the building through the flue 9. However, the heat in the flue 9 is reused by being supplied to the living area side as living area heating and to the hoistway 1 side as hoistway air heating by the heat radiating panel 10. Is done.
The heat (radiant heat) in the hoistway 1 is recovered by the direct heat recovery heat exchanger 11a, and is sent to the floor heating panel 12 through the duct 13 using, for example, a blower as warm air. .
The warm air sent by the duct 13 passes through the warm air passage hole 12 a of the floor heating panel 12, is dispersed by the warm air dispersion hole 15 of the floor warm air dispersion panel 14, and then passes through the outlet 16. It blows out into the said car 2, and the air in the said car 2 is warmed. Here, the floor warm air dispersion panel 14 can distribute the warm air to every corner of the car 2, thereby eliminating uneven heating. The warm air blown out from the air outlet 16 of the floor portion of the car 2 is discharged from the inside of the car 2 into the hoistway 1 through the outlet 18 of the ceiling portion of the car 2. By passing warm air through the car 2 in this manner, new warm air can be attracted from the air outlet 16 to the car 2.
If warm air stays in the hoistway 1, the quality of the air deteriorates. Therefore, the warm air in the hoistway 1 is finally transferred from the hoistway 1 through the ventilation port 22. It is discharged outside the building via the attic 21.

The heat (radiant heat) in the hoistway 1 is also recovered by the indirect heat recovery heat exchanger 11 b provided in the car 2. Here, when the heat exchanger 11b for indirect heat recovery is provided in the car 2 so as to be as close as possible to the floor heating panel 12 exposed in the hoistway 1, the point of heat recovery efficiency Is advantageous. The heat recovered by the indirect heat recovery heat exchanger 11 b is stored in the heat medium 20. The heat medium 20 that has accumulated heat circulates in the floor heating panel 12 and radiates heat by the circulation pump 19, and warms the air in the vicinity of the floor in the car 2. In addition, there is an effect of further warming the warm air supplied from the duct 13 passing through the warm air passage hole 12a of the floor heating panel 12.
In this way, the heat in the hoistway 1 recovered by the indirect heat recovery heat exchanger 11b is stored in the heat medium 20 and circulated in the floor heating panel 12, thereby starting floor heating. In this case, the rise of the heating effect can be accelerated.
The circulation pump 19 is used only at the start of floor heating. When the heat medium 20 comes to circulate stably, the circulation pump 19 is stopped and thereafter the heat medium 20 is circulated by natural circulation.

In the elevator floor heating apparatus configured as described above, the exhaust heat of the stove is reused by supplying it as air heating in the hoistway, and further, the heat in the hoistway is directly heated in the hoistway. By recovering with a heat exchanger for recovery and sending it directly to the car as hot air, the exhaust heat of the stove can be effectively used to reduce energy consumption during floor heating.
In addition, the heat in the hoistway is collected by an indirect heat recovery heat exchanger provided in the car and stored in the heat medium, and the heat medium that stores the heat is circulated in the floor heating panel of the car floor. The same effect as described above can be obtained by dissipating heat.
The above is particularly effective when the user gets on the car with bare feet in the home elevator.
In addition, although the elevator floor heating apparatus provided with both the heat exchanger for direct heat recovery and the heat exchanger for indirect heat recovery was demonstrated here, the heat exchanger for direct heat recovery and the heat exchanger for indirect heat recovery are described. By providing only one of them, it is possible to obtain an appropriate floor heating effect.
