MODE FOR CARRYING OUT THE INVENTION

[0010] Hereinafter, the elevator car and elevator according to the example of the embodiment will be described with reference to FIGS. 1 to 10. In addition, the same reference numerals are assigned to the common members in each figure.

[0011] First, the configuration of the elevator car according to the example of the embodiment (hereinafter referred to as "this example") will be described with reference to FIGS. 1 and 2. FIG. 1 is a schematic configuration diagram showing a configuration example of the elevator car of this example. FIG. 2 is a cross-sectional view showing the inside of the car body of the car.

[0012] As shown in FIG. 1, the elevator car 1 of this example includes a car body 10, a frame 11 that supports the car body 10, an air conditioner 12, and a door unit 24. The car body 10 is supported by the frame 11 via a vibration isolator (not shown).

[0013] As shown in FIGS. 1 and 2, the car chamber 10 has a ceiling panel 20, a front panel 21, three side panels 22, and a floor panel 23. The floor panel 23 is formed in a rectangular shape and serves as the floor of the car chamber 10. Around the floor panel 23, the front panel 21 and the three side panels 22 are erected perpendicular to the floor panel 23.

[0014] An entrance / exit is provided in the front panel 21. A car door that constitutes the door unit 24 is installed at the entrance / exit of the front panel 21 so as to be openable and closable. Also, a door sill 25 is installed at the lower part in the vertical direction of the front panel 21. The car door of the door unit 24 is movably supported by the door sill 25.

[0015] The ceiling panel 20 is installed so as to close the upper opening formed by the front panel 21 and the three side panels 22. And the ceiling panel 20 faces the floor panel 23 in the vertical direction.

[0016] An air conditioner 12 is installed at the upper part in the vertical direction of the ceiling panel 20. The air conditioner 12 is a circulation type air conditioner that circulates air in the car chamber 10. The air conditioner 12 has a blowing duct 13 that blows cold air or warm air into the car chamber 10 and a suction duct 14 that sucks air into the car chamber 10. The blowing duct 13 is connected to the air conditioner 12 via a pipe 15. Similarly, the suction duct 14 is connected to the air conditioner 12 via a pipe 16.

[0017] The air supply duct 13 is installed at the end of the ceiling panel 20 on the front panel 21 side. The suction duct 14 is installed at the end of the ceiling panel 20 on the side panel 22 (hereinafter referred to as the rear panel) side that faces the front panel 21. Here, an example in which the air supply duct 13 is installed on the front panel 21 side and the suction duct 14 is installed on the rear panel side has been described, but it is not limited thereto. For example, the air supply duct 13 may be installed on the rear panel side and the suction duct 14 may be installed on the front panel 21 side. Alternatively, the air supply duct 13 and the suction duct 14 may be installed at the end of the ceiling panel 20 on the side panel 22 side different from the front panel 21 and the rear panel.

[0018] Also, as shown in FIG. 2, the ceiling panel 20 has a design panel 26 and a ceiling frame 31. The design panel 26 is arranged so as to face the internal space of the car body 10. Lighting fixtures are installed on the design panel 26. The design panel 26 is formed smaller than the floor panel 23. Therefore, a gap is formed between the outer edge of the design panel 26 and the front panel 21 and the three side panels 22. The design panel 26 is supported by the ceiling frame 31 at the upper part in the vertical direction of the car body 10.

[0019] The air supply duct 13 is installed on the ceiling frame 31. Further, a blow-out port 31a communicating with a duct port 13a provided below the air supply duct 13 is formed on the ceiling frame 31. Further, the blow-out port 31a is formed on the front panel 21 side, that is, on the wall surface side forming the car body 10, rather than the outer edge of the design panel 26. Further, a branch member 40 is arranged above the blow-out port 31a in the vertical direction. The air blown into the car body 10 through the blow-out port 31a advances as shown by the arrow in the figure and circulates in the car body 10.

[0020] In this example, by providing the blow-out port 31a on the ceiling frame 31 arranged above the design panel 26 in the vertical direction, the blow-out port 31a is less likely to be visually recognized from inside the car body 10. Thereby, it is possible to suppress a decrease in the aesthetic appearance of the car body 1 due to the exposure of the blow-out port 31a.

[0021] FIG. 3 is a schematic configuration diagram showing the configuration of the air duct 13. As shown in FIG. 3, the air duct 13 is disposed on the surface of the ceiling frame 31. The air duct 13 has a cover 18 as a rectangular outer wall housing indicated by a two-dot chain line. Inside the cover 18, a first air supply wall 32 that forms an air supply path is obliquely disposed. On the upper surface 18a of the cover 18, an air pipe port 13b for connecting the pipe 15 is formed. On the lower surface 18b of the cover 18, a duct port 13a communicating with the air outlet 31a is formed. The duct port 13a is formed along the lower end of the front surface 18c of the cover 18.

[0022] The first air supply wall 32 is processed by bending the tip of a flat steel plate so that the cross section becomes L-shaped, and a rectangular inclined surface 32a and a rectangular introduction surface 32b having a larger area than the inclined surface 32a are formed. The first air supply wall 32 is fixed to the side surface 18d of the cover 18 such that the tip portion of the inclined surface 32a is close to the duct port 13a and the introduction surface 32b is obliquely disposed within the air duct 13.

[0023] At the lower part of the front surface 18c of the cover 18, a lower inclined surface 33a bent so as to incline inward is provided. The air sent from the air conditioner 12 into the air duct 13 through the air pipe port 13b hits the introduction surface 32b of the first air supply wall 32 disposed obliquely, and is guided to the duct port 13a through the air supply path constituted by the inclined surface 32a as an inclined surface portion and the lower inclined surface 33a.

[0024] Near the center of the inclined surface 32a of the first air supply wall 32, a branching member 40 is attached. The branching member 40 in this example is made of a heat-insulating material. For example, a rubber member is processed into a triangular shape. By fixing the branching member 40 with an adhesive near the center of the inclined surface 32a, the central part of the duct opening 13a is blocked, and the duct opening 13a is substantially divided into two parts. That is, the air branched in different directions when hitting the branching member 40 is blown into the cage chamber 10 through the blowing outlets 31a from each of the divided duct openings 13a.

[0025] Figure 4 is an explanatory diagram showing an enlarged view around the blowing outlet 31a. As shown in Figure 4, inside the air supply duct 13, a first air supply wall 32 forming an air supply path is arranged. Also, a second air supply wall 33 formed by the front surface 18c of the cover 18 of the air supply duct 13 is arranged so as to face the first air supply wall 32. That is, the first air supply wall 32 is arranged inside the cage chamber 10 more than the second air supply wall 33, and the second air supply wall 33 is arranged on the side of the front panel 21. And the first air supply wall 32 and the second air supply wall 33 form an air supply path for the air blown from the air supply duct 13 into the cage chamber 10.

[0026] In this example, the second air supply wall 33 is constituted by using the cover 18 of the air supply duct 13. However, alternatively, a member processed to have an inclined surface inside the front surface 18c of the cover 18 may be fixed to constitute the second air supply wall.

[0027] A lower inclined surface portion 33a is formed on the lower end side of the front surface 18c of the cover 18 which is the second air supply wall 33. The lower inclined surface portion 33a is inclined in a direction continuously away from the front panel 21 of the cage chamber 10 as the front surface 18c of the cover 18 approaches the blowing outlet 31a. That is, the lower inclined surface portion 33a is inclined toward the inside of the cage chamber 10.

[0028] As described above, the first air supply wall 32 has an inclined surface portion 32a and an introduction surface 32b, and the inclined surface portion 32a is inclined toward the inside of the car body compartment 10 in the same manner as the inclined surface portion 33a of the second air supply wall 33. Thus, by providing the inclined surface portions 32a and 33a that are inclined toward the inside of the car body compartment 10 on the first air supply wall 32 and the second air supply wall 33, the direction of the air blown out from the air outlet 31a can be directed toward the inside of the car body compartment 10, that is, in a direction away from the wall surface. That is, it is possible to prevent the air blown out from the air outlet 31a from hitting the front panel 21 or the side panel 22. For example, when blowing out cold air during cooling, it is possible to suppress the occurrence of condensation on the front panel 21 and the side panel 22. In addition, since the air is blown out from the air outlet 31a toward the inside of the car body compartment 10, the air can be efficiently sucked from the suction duct 14, and the circulation efficiency of the air conditioner 12 can be increased.

[0029] In addition, in this example, by arranging the branch member 40 at a portion where the inclined surface portion 32a of the first air supply wall 32 and the inclined surface portion 33a of the second air supply wall 33 face each other to form an air supply path, the air carried to the air outlet 31a can be reliably branched. Then, the branched air can be blown out from the air outlet 31a toward the inside of the car body compartment 10.

[0030] In addition, the inclined surface portions 32a and 33a for changing the air direction are arranged above the air outlet 31a in the vertical direction. Further, as described above, the air outlet 31a is arranged above the design panel 26 in the vertical direction. As a result, it becomes difficult to visually recognize the inclined surface portions 32a and 33a from inside the car body compartment 10, and it is possible to suppress the inclined surface portions 32a and 33a from being exposed and degrading the aesthetic appearance of the car body 1.

[0031] In addition, the length H1 of the horizontal distance between the air outlet 31a and the design panel 26 is set according to the inclination angles of the inclined surfaces 32a and 33a of the first air supply wall 32 and the second air supply wall 33, that is, the direction of the air blown out from the air outlet 31a (hereinafter simply referred to as "wind direction") L1. Specifically, it is set to the length H1 of the interval during which the air blown out from the air outlet 31a does not hit the outer edge portion 26a of the design panel 26. Thereby, it is possible to prevent the wind direction L1 from changing or the heating and cooling efficiency from decreasing due to the air hitting the design panel 26.

[0032] An example of setting the length H1 of the distance between the air outlet 31a and the design panel 26 according to the inclination angles of the inclined surfaces 32a and 33a, that is, the wind direction L1, has been described, but it is not limited thereto. For example, the inclination angles of the inclined surfaces 32a and 33a may be set according to the length H1 of the distance between the air outlet 31a and the design panel 26. That is, according to the length H1 of the distance between the air outlet 31a and the design panel 26, the inclination angles of the inclined surfaces 32a and 33a are set to an angle at which the air blown out from the air outlet 31a does not hit the outer edge portion 26a of the design panel 26.

[0033] In addition, the introduction surface 32b is continuously formed at the end of the inclined surface 32a on the side opposite to the end on the air outlet 31a side. The introduction surface 32b is inclined in the direction approaching the front panel 21 as it approaches the inclined surface 32a, that is, in the direction approaching the second air supply wall 33. In the air supply path formed by the first air supply wall 32 and the second air supply wall 33, a portion where the opening diameter is narrowed (hereinafter referred to as a constriction portion) Q1 is formed by the introduction surface 32b. By providing the constriction portion Q1 in the air supply path in this way, the flow velocity of the air passing through the air supply path can be increased, and the heating and cooling effect by the air conditioner 12 can be enhanced.

[0034] FIG. 5 is a front view of the car body for explaining the flow of air circulating in the car body 10. The solid arrows in Fig. 5 represent the state in which the air blown out from the air outlet 31a circulates within the cage chamber 10. In this example, the air branched when hitting the branch member 40 is blown out in different directions within the cage chamber 10 through the air outlets 31aL and 31aR formed at two locations. That is, the air blown out from the air outlet 31aL formed on the left side in the figure flows toward the left side panel 22L, and the air blown out from the air outlet 31aR formed on the right side in the figure flows toward the right side panel 22R. Hereinafter, the flow of air flowing out in different directions from the air outlet 31a is referred to as a divided flow. The air blown out from the air outlet 31a moves downward in the cage chamber 10 in a divided state.

[0035] At the same time, in the space between the divided air flows, as shown by the dotted arrows in Fig. 5, a rotational flow (hereinafter referred to as a return flow) is generated in which the air existing in the cage chamber 10 circulates while rotating. Such a return flow S is generated by the air existing in the cage chamber 10 moving so as to follow the momentum of the air blown out from the air outlet 31a. Further, due to the upward to downward flow of the return flow, the moving speed of the air blown out from the air outlet 31a becomes faster. That is, by the divided flow and the return flow generated in the cage chamber 10, the flow velocity of the air circulating within the cage chamber 10 can be increased, and the cooling and heating efficiency by the air conditioner 12 can be enhanced. Also, air can be efficiently sucked from the suction duct 14, and the circulation efficiency of the air conditioner 12 can be enhanced.

[0036] Also, in this example, since the branch member 40 is arranged in the ventilation path, the air sent from the air conditioner 12 can be applied to the branch member 40. Thereby, it is possible to prevent the cooled air during cooling from directly hitting the ceiling panel 20, and it is possible to prevent condensation from occurring on the design surface of the ceiling panel 20.

[0037] Further, by forming the branch member 40 into a triangular shape, the air blown from the air conditioner 12 can be accelerated by directing it to the apex of the triangle and then along the slopes of both sides. As a result, even in a state of being split, the speed of the air blown into the car body compartment 10 from the air outlet 31a can be increased, and the heating and cooling efficiency by the air conditioner 12 can be enhanced.

[0038] In this example, the shape of the branch member 40 is configured as a triangle. However, as shown in FIG. 6, the shape of the branch member 60 may be configured as a trapezoid. Also in this case, by directing the air blown from the air conditioner 12 along the slopes of the trapezoid, the flow velocity of the split air blown into the car body compartment 10 can be increased.

[0039] Also, as shown in FIG. 7, the shape of the branch member 40 may be configured as a rectangle. Since the branch member 40 has a thickness above the air outlet 31a in the vertical direction, it is possible to prevent the cooled air during cooling from directly hitting the ceiling panel 20. Therefore, it is possible to prevent condensation from occurring on the ceiling panel 20 when the air blown from the air conditioner 12 is split.

[0040] Also, by forming the branch member 40 of a member with high heat insulation properties (for example, rubber or sponge), it is possible to prevent the temperature of the branch member 40 from dropping due to the cold air blown from the air conditioner 12 during cooling. As a result, it is possible to prevent the ceiling panel 20 and the design panel 26 from being cooled by the branch member 40 and condensation from occurring.

[0041] FIG. 8 is a perspective configuration diagram of the car body compartment for explaining the flow of air circulating in the car body compartment. As shown in Fig. 8, two rectangular air outlets 31a are provided along the end of the ceiling panel 20 on the front panel 21 side. The air blown into the car body compartment 10 from the two air outlets 31a flows along the front panel 21, the floor panel 23, and the side (rear) panel 22 in a divided state as shown by the solid arrows in the figure, and is sucked into the suction duct 14 from the air outlet 31b formed on the back panel 22 side of the ceiling panel 20. Also, as described above, a backflow is generated in the car body compartment 10 due to the flow of the air blown out from the air outlet 31a.

[0042] Multiple backflows occur as shown by the dotted arrows in the figure. For example, a backflow S1 that moves in a direction parallel to the ceiling panel 20 at the upper part of the car body compartment 10, a backflow S2 that moves in a direction of slightly rotating vertically near the lower part of the car body compartment 10, a backflow S3 that moves in a direction of rotating greatly vertically between the floor panel 23 and the ceiling panel 20 of the car body compartment 10, etc. occur. Note that the backflows shown in this example are only some examples, and actually, a large number of backflows that move complexly in various directions occur. In this way, by generating multiple backflows in the car body compartment 10, the circulation efficiency of the air in the car body compartment 10 can be increased, and the heating and cooling effects in the car body compartment 10 can be enhanced. Furthermore, by increasing the flow velocity of the air blown out from the air outlet 31a by the multiple backflows, the air can be efficiently sucked from the suction duct 14, and the circulation efficiency of the air conditioner 12 can be increased.

[0043] Fig. 9 is an enlarged view of the air outlet in Fig. 8 seen from above. Due to the momentum of the air blown into the car body compartment 10 from the air outlet 31a, a backflow S as shown by the arrow in the figure occurs near the longitudinal end of the air outlet 31a in the car body compartment 10. Note that the backflow occurs at least at two locations for one air outlet. That is, in this example, by providing the air outlet 31a at two locations, the number of backflows generated in the car body compartment 10 can be increased compared to the case where there is one air outlet, and the circulation efficiency of the air in the car body compartment 10 can be enhanced.

[0044] FIG. 10 is an enlarged view around the air outlet 31a for explaining the flow of the air blown out from the air outlet 31a. As described above, in this example, by providing the inclined surfaces 32a and 33a, as indicated by the solid arrows in the figure, the air blown out from the air outlet 31a can be directed in a direction away from the wall surface of the front panel 21. Further, by diverting the air blown out from the air outlet 31a by the branch member 40, a recirculation flow S that flows toward the wall surface direction of the front panel 21 in the car body compartment 10 can be generated as indicated by the dotted arrows in the figure. Then, by allowing this recirculation flow S to flow between the wall surface and the air blown out from the air outlet 31a, it is possible to prevent the cold air blown out from the air outlet 31a during cooling from approaching the wall surface and prevent condensation from occurring on the wall surface. Also, since the recirculating air is the air that was present in the car body compartment 10, the temperature of the air due to the recirculation is higher than the temperature of the air blown out from the air outlet 31a. Therefore, by flowing the high-temperature recirculation flow S between the cold air blown out from the air outlet 31a and the wall surface, it is possible to prevent condensation from occurring on the wall surface.

[0045] Note that the present invention is not limited to the embodiments described above and shown in the drawings, and various modifications can be made without departing from the gist of the invention described in the claims. For example, the shape of the branch member 40 may be any shape that can branch the air sent to the air duct 13 in a plurality of directions.
