Description

  Embodiments described herein relate generally to an elevator car.

  Since the elevator car is a closed room, odors may adhere to the car, which may cause discomfort to the user. In addition, viruses and fungi brought into the cage may proliferate and become unsanitary.

  Therefore, conventionally, a basket including an odor detection sensor and an ion generator has been proposed. In this basket, the odor in the basket is detected by an odor detection sensor, and when the odor becomes a certain strength, the ion generator generates ions. Specifically, the ion generator applies a high voltage to the discharge needle to generate plasma discharge, thereby ionizing the air around the discharge needle. Due to the ions generated by the ion generator, the odor-causing substance is oxidatively decomposed and viruses are inactivated. As a result, the inside of the basket can be deodorized and antibacterial.

  When the discharge needle of the ion generator is repeatedly discharged, it may deteriorate due to a chemical change. When the discharge needle is deteriorated, the generated ions may decrease or harmful ozone may be generated. For this reason, in the said conventional basket, in order to maintain a deodorizing effect and an antibacterial effect, it is necessary to replace | exchange an ion generator regularly.

  In addition, when the ion generator is used continuously for a long period of time, its life is shortened. For this reason, in order to extend the lifetime of the ion generator, a control device for intermittently driving the ion generator is required.

  Thus, in the conventional basket provided with the ion generator, in order to maintain the deodorizing effect and the antibacterial effect, it is necessary to construct a regular replacement work and a control system.

  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
The elevator car according to the first embodiment will be described with reference to FIGS. FIG. 1 is a perspective view showing a schematic configuration of the basket according to the present embodiment. FIG. 2 is a cross-sectional view of FIG.

  As shown in FIGS. 1 and 2, the basket according to this embodiment includes a basket body 1, a lighting fixture 2, and a ventilation device 3.

  The car body 1 includes a ceiling 11, a side plate 12, a floor plate 13, and a door 14. In the example of FIG. 1, the basket includes only one door 14, but may include two. Hereinafter, the inside of the basket body 1 is referred to as a cage room. Although not shown in the drawings, an operation panel including a cage call button, a door open button, a door close button, and the like is provided in the cage room.

  The lighting fixture 2 is direct lighting and is installed on the ceiling 11 in the room. FIG. 3 is a partially enlarged cross-sectional view in which the ceiling 11 portion of FIG. 1 is enlarged. As shown in FIG. 3, the lighting fixture 2 includes a lighting case 21, a light source 22, a frame body 23, a light diffusion member 24, a translucent sheet 25, and a photocatalytic compound 26.

  The lighting case 21 is a housing for the lighting case 21. The light source 22 and the frame body 23 are fixed with respect to the lighting case 21. By using the lighting case 21, workability of the lighting fixture 2 can be enhanced.

  The lighting case 21 in FIG. 3 includes a top plate 211 and side plates 212. The top plate 211 is fixed to the ceiling 11. The side plate 212 extends in a direction perpendicular to the top plate 211 (downward in FIG. 3) and has an opening 213 at least in part.

  FIG. 4 is a plan view showing an example of the opening 213 provided in the side plate 212. In the example of FIG. 4, the side plate 212 is provided with a plurality of substantially rectangular openings 213. The side plate 212 may be provided with such an opening 213 on the entire surface or a part thereof. Further, the shape of the opening 213 can be arbitrarily designed.

  However, each opening 213 is preferably formed to be small or narrow so that dust, insects, and the like (hereinafter referred to as “dust etc.”) do not easily enter the inside of the lighting case 21. For example, the opening 213 in FIG. 4 is preferably formed with a major axis of 20 cm or less and a minor axis of 2 cm or less.

  Thus, by providing the opening 213 in the side plate 212, the air inside the lighting case 21 and the air outside can be ventilated. Moreover, the lighting case 21 can be reduced in weight.

  In addition, the side plate 212 may have an opening corresponding to a ventilation port 32 of the ventilation device 3 described later, in addition to the opening 213 for ventilation as shown in FIG.

  The lighting case 21 may include a reflective material that reflects light from the light source 22 on at least a part of the inner surfaces of the top plate 211 and the side plate 212. The reflecting material may be a mirror or the inner surface of the lighting case 21 painted so as to easily reflect light. By providing a reflective material on the inner surface of the lighting case 21, the illuminance of the lighting fixture 2 can be improved.

  The light source 22 is fixed to the top plate 211 and irradiates light indoors. The light source 22 is, for example, an LED (Light Emitting Diode), an incandescent bulb, or a fluorescent lamp. In the example of FIG. 3, the lighting fixture 2 includes a plurality of light sources 22, but may include one. The light source 22 may be directly fixed to the ceiling 11. In this case, the illumination case 21 may include a flange for fixing the side plate 212 to the ceiling 11 instead of the top plate 211.

  The frame body 23 is an annular member formed of a metal such as aluminum or plastic, and is fixed to an end portion (lower end in FIG. 3) of the side plate 212 so as to face the top plate 211. The light diffusing member 24 and the translucent sheet 25 are fixed to the frame body 23. By using the frame body 23, the workability of the lighting fixture 2 can be improved.

  FIG. 5 is a perspective view showing an example of the frame body 23. In the example of FIG. 5, the frame 23 has a substantially square shape in plan view, and the translucent sheet 25 is fixed to the upper end of the frame 23 using a screw 251 and a fixing member 252. Details of the screw 251 and the fixing member 252 will be described later. Note that the shape of the frame 23 in plan view is not limited to a square shape, and can be designed in any shape that can be attached to the end of the side plate 212, such as a rectangle, a polygon, a circle, or an ellipse.

  The light diffusing member 24 is a plate-like member that is made of acrylic, plastic, glass, glass fiber fabric, or the like and diffuses light. As shown in FIG. 3, the light diffusion member 24 is fixed to the frame body 23 so as to cover one end (the lower end in FIG. 3) of the frame body 23. By arranging the light diffusing member 24 in this way, the light from the light source 22 is diffused by the light diffusing member 24 and irradiated into the room. Thereby, the lighting fixture 2 can irradiate the room uniformly. Moreover, by arranging the light diffusing member 24, the internal structure of the lighting fixture 2 (the inside of the light source 22 and the lighting case 21) is concealed to the user, and the aesthetics of the lighting fixture 2 can be improved.

  The translucent sheet 25 is a sheet-like member that transmits visible light. The translucent sheet 25 is fixed to the frame body 23 so as to cover the other end (the upper end in FIG. 3) of the frame body 23. The light from the light source 22 is diffused by the light diffusion member 24 after passing through the translucent sheet 25.

  By disposing the translucent sheet 25 in this way, entry of dust or the like into the inside of the frame body 23 is suppressed. Thereby, the fall of the beauty | look of the lighting fixture 2 by dust etc. accumulating on the light-diffusion member 24 can be suppressed. In order to suppress intrusion of dust or the like, the translucent sheet 25 preferably seals the inside of the frame body 23. The term “sealing” as used herein refers to closing the upper end of the frame body 23 to the extent that dust or the like does not enter.

  FIG. 6 is a partial enlarged cross-sectional view in which a fixing portion of the translucent sheet 25 with respect to the frame body 23 is enlarged. In the example of FIG. 6, the translucent sheet 25 is fixed to the upper end of the frame body 23 using screws 251 and a plate-like fixing member 252.

  Specifically, the screw 251 is fixed to the upper end of the frame body 23 so as to press the fixing member 252 against the upper end of the frame body 23, and the translucent sheet 25 is connected to the upper end of the frame body 23. And the fixing member 252. As shown in FIG. 6, at least a part of the fixing member 252 in contact with the translucent sheet 25 is protruded to the upper end side of the frame body 23, thereby fixing the translucent sheet 25 more strongly. The translucent sheet 25 can be made difficult to shift.

  In addition, the fixing method of the translucent sheet | seat 25 is not restricted to the example of FIG. The translucent sheet 25 may be directly fixed to the upper end of the frame body 23 with an adhesive or a screw.

  As the translucent sheet 25, any transparent sheet such as a glass, acrylic, or plastic sheet or a fibrous sheet can be used. However, in the present embodiment, since the translucent sheet 25 is used as a carrier for supporting the photocatalytic compound 26, it is preferably a fibrous sheet. By using a fibrous sheet as the translucent sheet 25, the photocatalytic compound 26 can be efficiently fixed to the translucent sheet 25.

  The photocatalytic compound 26 is a compound containing a photocatalyst. The photocatalyst exhibits a catalytic effect when irradiated with light, and reacts with oxygen and water in the nearby air to generate active oxygen and hydroxyl radicals. Oxidizing power of active oxygen and hydroxyl radicals decomposes odor-causing substances in the air and inactivates viruses. That is, the photocatalyst exhibits a deodorizing effect and an antibacterial effect when irradiated with light.

  In the present embodiment, as shown in FIG. 3, the photocatalytic compound 26 is applied to one surface (the upper surface in FIG. 3) of the translucent sheet 25 to form a layer on the upper surface of the translucent sheet 25. That is, the photocatalytic compound 26 is supported on the translucent sheet 25. The photocatalytic compound 26 may be applied in advance to the translucent sheet 25, or may be applied to the translucent sheet 25 after fixing the translucent sheet 25 to the frame body 23. In any case, when the frame body 23 is fixed to the lighting case 21 and the light source 22 is turned on, the photocatalytic compound 26 is irradiated with light from the light source 22 and exhibits a deodorizing effect and an antibacterial effect. As a result, the interior of the basket is deodorized and antibacterial.

  The photocatalyst compound 26 may be a titanium oxide compound containing titanium oxide as a photocatalyst, or a tungsten oxide compound containing tungsten oxide as a photocatalyst. Since the light from the light source 22 contains a lot of visible light components, the photocatalytic compound 26 is preferably a tungsten oxide compound containing tungsten oxide that exerts a strong catalytic effect when irradiated with visible light.

  The ventilation device 3 circulates indoor air by connecting the air inlet 31 and the air outlet 32 and exhausting the air sucked from the air inlet 31 through the air outlet 32. Although the ventilation device 3 is not shown, the ventilation device 3 includes a motor and a fan for intake and exhaust of air. In the example of FIG. 3, the ventilator 3 is installed in the cage room and is fixed to the side plate 212, but may be fixed to the ceiling 11 or the side plate 12. Moreover, the ventilator 3 may be installed outside the cage.

  The air inlet 31 is disposed so as to open toward the outside of the lighting fixture 2. Further, the exhaust port 32 opens toward the side plate 212 and is arranged so that at least a part thereof overlaps with the opening 213 of the side plate 212. When the side plate 212 has an opening corresponding to the exhaust port 32, the exhaust port 32 may be arranged so as to correspond to the opening.

  Next, the operation of the basket in the present embodiment will be described with reference to FIGS. 7 and 8 are partially enlarged cross-sectional views for explaining the airflow generated by the ventilation device 3. The arrows in FIGS. 7 and 8 schematically show the airflow generated by the ventilation device 3.

  As shown in FIG. 7, the ventilation device 3 supplies air outside the lighting fixture 2 in the room from the air inlet 31 and exhausts it from the air outlet 32. The air exhausted from the exhaust port 32 is exhausted into the space between the lighting case 21 and the photocatalytic compound 26 in the lighting fixture 2 through the opening 213.

  The air exhausted into this space is deodorized and antibacterial by the photocatalytic compound 26 irradiated with light from the light source 22. As shown in FIG. 8, the deodorized and antibacterial air flows out of the luminaire 2 in the room through the opening 213 of the side plate 212 according to the air flow generated by the ventilation device 3. The air that has flowed out of the luminaire 2 is supplied again from the air inlet 31 of the ventilation device 3. As a result, the indoor air circulates between the outside of the lighting fixture 2 and the inside of the lighting fixture 2 (the space between the lighting case 21 and the photocatalytic compound 26).

  As described above, the basket according to this embodiment includes the photocatalytic compound 26 that is irradiated with light from the light source 22, and the photocatalytic compound 26 can deodorize and antibacterial the indoor air. The photocatalytic compound 26 exhibits a catalytic effect as long as it is irradiated with light from the light source 22. Therefore, the basket according to the present embodiment can easily maintain the deodorizing effect and the antibacterial effect without performing a special maintenance work for maintaining the deodorizing effect and the antibacterial effect.

  Moreover, in this embodiment, the ventilation apparatus 3 circulates indoor air between the outer side of the lighting fixture 2, and an inner side. And the photocatalyst compound 26 is arrange | positioned on the flow path of the airflow which this ventilator 3 produces. Thereby, the indoor air can be efficiently deodorized and antibacterial.

  In the above description, the photocatalytic compound 26 is applied only to the upper surface of the translucent sheet 25, but may be applied to other portions of the room. For example, the photocatalytic compound 26 may be applied to a part of the wall surface of the room (the ceiling 11, the side plate 12, the floor plate 13, and the door 14), or a part of the lighting fixture 2 (the top plate 211, the side plate 212, And the light diffusion member 24). That is, a part of the wall surface of the room or a part of the lighting fixture 2 may be used as a carrier for the photocatalytic compound 26. In either case, the photocatalytic compound 26 is irradiated with light from the light source 22 and exhibits a deodorizing effect and an antibacterial effect.

  Further, the intake port 31 and the exhaust port 32 of the ventilation device 3 may be reversed. In this case, the airflow directions shown in FIGS. 7 and 8 are reversed. Further, the basket may include a ventilator that circulates indoor air and outdoor air separately from the ventilator 3.

(Second Embodiment)
The elevator car according to the second embodiment will be described with reference to FIG. In this embodiment, another example of the fixing method of the translucent sheet 25 will be described. FIG. 9 is a partial enlarged cross-sectional view in which a fixing portion of the translucent sheet 25 with respect to the frame body 23 is enlarged.

  In the present embodiment, as shown in FIG. 9, the frame body 23 has a groove 231 at the upper end. The groove 231 is formed on the entire periphery of the upper end of the frame body 23. The translucent sheet 25 is fixed by being sandwiched between the groove 231 and the fixing member 253. For this reason, the translucent sheet | seat 25 which concerns on this embodiment has the flexibility which can be embedded in the groove | channel 231. FIG. The translucent sheet 25 is preferably a fibrous sheet, for example.

  In the present embodiment, the fixing member 253 is an annular elastic member formed of rubber or plastic. The fixing member 253 is formed to be thicker than the diameter of the groove 231 and is fitted into the groove 231 in an elastically deformed state.

  With this configuration, in this embodiment, a tool for fixing the translucent sheet 25 to the frame body 23 becomes unnecessary, and the workability of the lighting fixture 2 can be improved. Further, the entire circumference of the translucent sheet 25 is fixed by a fixing member 253. Thereby, wrinkles can be made more difficult on the translucent sheet 25.

(Third embodiment)
The elevator car according to the third embodiment will be described with reference to FIGS. In the present embodiment, a case where the photocatalytic compound 26 is not applied to the translucent sheet 25 will be described. FIG. 10 is a partial enlarged cross-sectional view in which the ceiling 11 portion of the basket according to the present embodiment is enlarged. In the basket of FIG. 10, the photocatalytic compound 26 is applied to the inner surface of the side plate 212 instead of the upper surface of the translucent sheet 25. Other configurations are the same as those of the first embodiment.

  FIG.11 and FIG.12 is the elements on larger scale explaining the airflow which the ventilator 3 produces. As shown in FIGS. 11 and 12, the side plate 212 is positioned on the flow path of the airflow generated by the ventilation device 3. For this reason, when the photocatalyst compound 26 is applied to the inner surface of the side plate 212, the photocatalyst compound 26 can be disposed on the flow path of the air flow generated by the ventilation device 3. Therefore, even in the basket according to the present embodiment, the indoor air can be efficiently deodorized and antibacterial as in the first embodiment.

  In addition, when apply | coating the photocatalyst compound 26 to the inner surface of the side plate 212, a fibrous sheet may be stuck on the inner surface of the side plate 212, and the photocatalyst compound 26 may be apply | coated on it. Thereby, the photocatalytic compound 26 can be efficiently fixed to the inner surface of the side plate 212.

  The photocatalytic compound 26 may be applied not only to the inner surface of the side plate 212 but also to the inner surface of the top plate 211 or a part of the wall surface in the room.

(Fourth embodiment)
The elevator car according to the fourth embodiment will be described with reference to FIG. This embodiment demonstrates the case where the lighting fixture 2 is indirect lighting. FIG. 13 is a partially enlarged cross-sectional view in which the ceiling 11 portion of the basket according to the present embodiment is enlarged.

The bottom plate 214 extends from the other end of the side plate 212 in a direction parallel to the ceiling 11. The light source 22 is arranged on the bottom plate 214 of the illumination case 21 so as to irradiate light toward the ceiling 11.

  The reflecting material 27 is fixed to the ceiling 11, is irradiated with light from the light source 22, and reflects the irradiated light. The room is illuminated by the reflected light of the reflecting material 27. The reflective material 27 can be formed of any material that reflects light.

  In the present embodiment, the photocatalytic compound 26 is applied to one surface (the lower surface in FIG. 13) of the reflective material 27. That is, in this embodiment, the reflective material 27 is used as a carrier for the photocatalytic compound 26.

  As described above, the basket according to this embodiment includes the photocatalytic compound 26, and the photocatalytic compound 26 is irradiated with light from the light source 22. Therefore, similarly to the first embodiment, the basket according to the present embodiment can easily maintain the deodorizing effect and the antibacterial effect without performing special maintenance work for maintaining the deodorizing effect and the antibacterial effect. Can do.

  In the present embodiment, the basket may not include the ventilation device 3 that circulates indoor air. In the lighting fixture 2 of FIG. 13, the photocatalytic compound 26 is exposed from the lighting case 21, and the indoor air is efficiently circulated only by the indoor air circulation caused by the opening and closing of the door 14 and the movement of the user. This is because it can be deodorized and antibacterial.

  Alternatively, a fibrous sheet may be attached to the lower surface of the reflecting material 27, and the photocatalytic compound 26 may be applied thereon, or the reflecting material 27 itself may be formed of a fibrous sheet. Thereby, the photocatalytic compound 26 can be efficiently fixed to the lower surface of the reflecting material 27.

  The pipe 42 connects the water storage tank 41 and the sprayer 43. The aqueous solution 44 stored in the water storage tank 41 is supplied to the sprayer 43 via the pipe 42.

  The sprayer 43 is installed in the basket room and is fixed to the lighting device 2. The sprayer 43 sprays the aqueous solution 44 supplied from the water storage tank 41 through the pipe 42. The timing at which the sprayer 43 sprays the aqueous solution 44 can be arbitrarily designed. For example, the sprayer 43 may spray at predetermined time intervals, or may spray according to the occurrence of an event such as opening / closing of a door or registration of a call. In addition, the sprayer 43 may be fixed to the ceiling 11 or the side wall 12, or may be installed outside the basket.

  As shown in FIG. 15, the nebulizer 43 sprays the aqueous solution 44 toward the airflow generated by the ventilation device 3. Thereby, the aqueous solution 44 sprayed by the sprayer 43 is efficiently sprayed indoors on the airflow.

  The aqueous solution 44 dispersed in the room adheres to the wall surface of the room, the lighting device 2, the user of the basket, and the like, and is irradiated with light from the lighting device 2. When the aqueous solution 44 is irradiated with light, the photocatalytic compound 26 contained in the aqueous solution 44 exhibits a catalytic effect, deodorizing and antibacterial the indoor air.

  As described above, the basket according to the present embodiment sprays the aqueous solution 44 indoors by the spraying device 4, and deodorizes and antibacterials the indoor air by the catalytic effect of the photocatalytic compound 26 contained in the aqueous solution 44. Therefore, the basket according to the present embodiment can easily maintain the deodorizing effect and the antibacterial effect simply by replenishing the water storage tank 41 with the aqueous solution 44.
