Conventional processing devices are designed to be operated by nurses, caregivers, and the like working in medical and nursing care settings while standing. It is not assumed that a person using a wheelchair opens the door by operating the handle, stores the wheelchair or other equipment inside the device, and then closes the door. Therefore, it is not easy for such people to handle the device.

Therefore, there is a need for a processing device that allows people in wheelchairs to easily open and close the door.

The ozone treatment apparatus of the present invention includes a casing having a space formed therein that can accommodate an object to be ozonated, an ozone generating section that generates ozone in the space, and an opening formed on the front surface of the casing. It includes a sealable opening/closing door and an opening/closing mechanism that moves the opening/closing door in the left-right direction of the housing. The housing can be configured, for example, in the shape of a rectangular parallelepiped. Further, the ozone generation section can include an excimer lamp or the like. The opening/closing door can be configured with one door, or can be configured with a double door.

In the present invention, the opening/closing mechanism moves the opening/closing door from the closed position to the side surface of the housing while maintaining the posture for sealing the opening and moving it toward the front of the housing. Here, "maintaining the posture when sealing the opening" refers to substantially maintaining the posture of the opening/closing door with respect to the opening, and strictly speaking, it means that the door is completely parallel to the opening without any change in posture. It is not limited. Further, "with movement toward the front side of the case" includes a configuration in which the posture is maintained while moving toward the side surface of the case.

There are various ways to move the opening/closing door, and considering wheelchair users, the opening/closing mechanism will move the opening/closing door from the sealed position toward the front of the case more. It is possible to have a configuration in which it is moved so that it becomes larger. For example, the opening/closing mechanism may move the opening/closing door along an elliptical orbit or a trajectory close to an elliptical orbit.

The opening/closing mechanism is also capable of moving the opening/closing door in a posture substantially parallel to the opening until the opening/closing door reaches a predetermined distance toward the front side of the casing at which the width of the opening/closing door becomes less than half the width of the opening/closing door. That is, it is movable toward the side surface of the housing while protruding forward from the closed position. After the opening/closing mechanism reaches a predetermined distance of the opening/closing door, it is possible to move the opening/closing door while rotating it. Here, "rotation" refers to a movement that changes the attitude of the opening/closing door with respect to the opening (casing).

The opening/closing mechanism is capable of moving the opening/closing door to the most open position. The position and posture of the opening/closing door at this time vary. For example, the opening/closing door can be configured such that the outer edge of the opening/closing door in the vertical direction of the casing is movable to a position beyond the front surface of the casing in the rearward direction. Further, it is also possible to configure the opening/closing door so that the inner edge in the vertical direction of the housing does not extend beyond the front surface along the left-right direction of the housing at the most open position of the opening/closing door.

When the opening/closing door is composed of a double door consisting of a pair of swinging doors, it is possible to further include an interlocking mechanism that moves the other door in conjunction with a manual opening/closing operation for one door.

The opening/closing door includes, for example, a handle near the inner edge of the housing in the vertical direction. The handle can be moved within a range of 90 cm or less along the left and right direction of the housing, and while the door moves from the closed position to the open position, the inner edge of the door must move within a distance of 60 cm or less from the front side to the front of the housing. It is possible to configure the device to move within a range of .

A processing device according to another aspect of the present invention is a processing device capable of performing at least one of deodorization, cleaning, disinfection, sterilization, and sterilization, and has a spatial area capable of accommodating objects to be processed. an opening/closing door that can seal an opening formed in the front of the housing, and an opening/closing mechanism that moves the opening/closing door in the left-right direction of the housing. , the housing is moved from the closed position to the side of the housing while protruding toward the front side of the housing. Here, "with protrusion" includes a movement of protruding toward the front side of the housing while moving toward the side of the housing.

According to the present invention, it is possible to provide a processing device that allows a person using a wheelchair to easily open and close the door.

FIG. 1 is a schematic perspective view of an ozone treatment apparatus according to this embodiment. FIG. 2 is a schematic front view of the ozone treatment apparatus.

The ozone treatment device 10 is a device that can deodorize and sterilize instruments and the like using ozone, and here includes a casing 15 that can accommodate mobility aids including wheelchairs. A wheelchair user can carry his or her wheelchair for competitions such as basketball and store it in the ozone treatment device 10 in order to deodorize and sterilize it. The opening/closing door 20 is provided on the front surface 15F of the housing 15, and is capable of sealing an opening 15P formed on the front surface 15F. Here, the opening/closing door 20 is constituted by a pair of hinged doors 20A and 20B.

The pair of hinged doors 20A and 20B are provided with handles 22A and 22B, respectively, and are arranged to face each other near the edges (inner edges in the vertical direction) 21A1 and 21B1 on the door center side along the vertical direction of the hinged doors 20A and 20B. Further, a lock handle 24 is provided below the handle 22B, and a solenoid mechanism (not shown) is provided on the back side of the hinged door 20B. A wheelchair user can freely open and close the door 20 by manually operating the handles 22A and 22B. Note that the opening/closing door 20 may also be opened/closed from inside the housing 15.

Considering that opening and closing operations are performed by a wheelchair user, the handles 22A and 22B may be installed within a range of 60 to 120 cm from under the floor. Further, the lock handle 24 may be installed within a range of 30 to 110 cm (preferably 40 to 90 cm) from under the floor.

An operation panel 30 is provided on the front surface 15F of the housing 15 between the side surface 15S2 of the housing 15 and the outer edge (vertical outer edge) 21B2 of the hinged door 20B along the vertical direction. Considering that the operation will be performed by a wheelchair user, the operation panel 30 may be installed within a range of 80 to 110 cm from under the floor. By operating the operation panel 30, the user can adjust the ozone treatment time and the like and start the ozone treatment.

The height H and width W of the casing 15 and the width W1 of the opening 15P sealed by the opening/closing door 20 are determined to be height H, width W, and W1, respectively, taking into consideration use by a wheelchair user. Here, the height H is set to be 140 cm or less, the width W1 is set to be 90 cm or more, and the width W is set to a value larger than the width W1. Further, the value of the width W is larger than the value of the height H, and the casing 15 is set in a horizontally long area.

FIG. 3 is a schematic block diagram of the ozone treatment apparatus 10.

The ozone treatment device 10 includes an ozone generation section 52 including an ozone generation means 51 (excimer lamp, etc.), an ozone removal section 54 including an ozone removal means (activated carbon, catalyst, etc.), a fan, etc., and a control section that controls the ozone treatment. 50. The control unit 50 controls the operations of the ozone generation unit 52 and the ozone removal unit 54 based on operation signals from the operation panel 30. Note that the ozone generation section 52 and the ozone removal section 54 may be configured integrally.

After the opening/closing door 20 is locked, when an operation to start ozone treatment is performed on the operation panel 30, the control section 50 controls the operation of the ozone generation section 52. Ozone is generated by ultraviolet irradiation from the excimer lamp and fills the housing 15. During the ozone treatment, the opening/closing door 20 is locked. Note that while it is detected that a person is inside the housing 15, the locking of the opening/closing door 20 is prohibited by the solenoid mechanism. Further, even during the ozone treatment, the door 20 can be opened and closed by unlocking and opening/closing operations from both the inside and outside of the door 20.

After the ozone treatment is completed, the control section 50 controls the operation of the ozone removal section 54 to remove ozone. When the ozone concentration becomes equal to or less than a predetermined value, ozone removal is ended and a display indicating the end is displayed on the operation panel 30.

FIG. 4 is a schematic perspective view of the ozone treatment apparatus when the door 20 is opened. FIG. 5 is a top view of the ozone treatment apparatus when the door 20 is open.

A pair of arms 60 and 70 are connected to one hinged door 20A of the opening/closing door 20 at the upper and lower ends of the housing in the vertical direction. The pair of arms 60 is composed of arms 60A and 60B, and one ends 61A and 61B are rotatably attached to a support 15T1 (not shown in FIG. 5) provided near the side surface 15S1 of the housing 15. The ends 62A and 62B are rotatably attached to the back side of the hinged door 20A.

A pair of arms 70 consisting of arms 70A and 70B have a similar configuration, and are connected to arms 60A and 60B by support columns 64A and 64B provided along the vertical direction of the housing, respectively.

The arms 60A and 60B have bent portions 63A and 63B, respectively, and the bent portion angle of the arm 60A is larger than that of the arm 60B. Furthermore, the end 61A of the arm 60A is located closer to the front of the housing than the end 61B of the arm 60B, and closer to the housing side 15S1 (see FIG. 5). On the other hand, the other end 62A of the arm 60A is connected to the hinged door 20A at a location closer to the housing side surface 15S1 than the end 62B of the arm 60B by a bent portion 63A.

These two pairs of arms 60 and 70 are each configured as a chain mechanism with one degree of freedom including the swing door 20A and the support column 15T1, and serve as an opening/closing mechanism for the swing door 20A. The two pairs of arms 60 and 70 move the hinged door 20A in a range from a position where the internal space S of the housing 15 is sealed (closed position) to the most open position (open position) shown in FIGS. 4 and 5. The trajectory during opening and closing is a nearly elliptical trajectory, and the hinged door 20A moves from the open position to the closed position on the same trajectory.

Regarding the hinged door 20B, two pairs of arms 80 and 90 are rotatably connected to pillars (not shown) near the rear side of the hinged door 20B and the side surface 15S2 of the housing 15, and follow a trajectory along a similar ellipse. The hinged door 20B is opened and closed. As will be described later, the two pairs of arms 80 and 90 are connected to the two pairs of arms 60 and 70 by an interlocking mechanism, and as one arm opens and closes, the other arm also opens and closes. Note that, depending on the size of the casing 15, a mechanism consisting of a pair of arms may be employed near the center of the casing in the vertical direction to open and close the door 20.

FIG. 6 is a diagram showing the movement of the arm 60 and the hinged door 20B when the door opens.

For example, when a wheelchair user operates the handle 22A to open the hinged door 20A in the closed position, the hinged door 20A protrudes forward and moves toward the side. During this time, the hinged door 20A moves while maintaining an attitude substantially parallel to the opening 15P. Immediately after the hinged door 20A starts moving, it protrudes forward as it is, and there is almost no movement in the left-right direction of the housing. As the amount of movement (movement distance) of the hinged door 20A toward the front side increases, the amount of movement of the case in the left-right direction increases. Such movement of the hinged door 20A continues until the hinged door 20A reaches a predetermined distance B that is less than half the width of the opening 15P.

The two pairs of arms 60 and 70 are connected to the two pairs of arms 60 and 70 on the opposite side by an interlocking mechanism 95. Therefore, the hinged door 20B also moves in conjunction with the movement of the hinged door 20A. The interlocking mechanism 95 is comprised of a rack and pinion type mechanism here.

When the hinged door 20A reaches a position where it protrudes forward by a predetermined distance B, the hinged door 20A begins to rotate (starts to turn) and its attitude relative to the opening 15P changes. The outer edge 21A2 along the vertical direction approaches the side surface 15S1, and the inner edge 21A1 along the vertical direction moves away from the opening 15P toward the front side. That is, the hinged door 20A rotates around to the side surface 15S1.

As shown in FIGS. 4 and 5, the vertical outer edge 21A of the hinged door 20A in the open position has moved toward the rear of the housing to a position exceeding the front surface 15F (opening 15P) of the housing 15. On the other hand, the vertical inner edge 21B of the hinged door 20A does not extend beyond the front surface 15F along the left-right direction of the housing.

As described above, the two pairs of arms 60 and 70 protrude forward with respect to the hinged door 20, increase the amount of movement toward the side of the housing as the amount of movement toward the front increases, and rotate with a change in posture. This movement makes it easier for a wheelchair user to open and close the door 20 even when operating the handle 22A.

Specifically, immediately after the wheelchair user pulls the handle 22A toward the user, the door does not pivot like a door with a hinge structure, and the swinging door 20A approaches the user, making it easier to pull the handle 24A. In addition, as the forward protrusion (movement amount) of the hinged door 20A increases, the amount of movement toward the side increases, so that the hinged door 20A does not approach the wheelchair user more than necessary, and the casing Natural handle operation can be continued to open the door 20 to the side.

Since the swing door 20A rotates around to the side surface 15S1, the amount of movement of the swing door 20A in the left and right direction is suppressed, and even if there is a space restriction at the installation location of the ozone treatment device 10, the swing door 20 can be moved to the open position. It becomes possible to move it. Furthermore, the operation panel 30 is hidden from view from the front side due to the open position of the hinged door 20B, and erroneous operation can be prevented. At the same time, since a hidden space is secured near the side surfaces 15S1 and 15S of the internal space S of the housing 15 when viewed from the front, it is possible to arrange the ozone generating section 52 and the like.

On the other hand, when closing the opening/closing door 20, the hinged door 20A moves along the front and back direction of the housing 15 near the closed position, so the wheelchair user can close the hinged door 20A while pressing it toward the housing 15. . Therefore, the hinged door 20A can reliably reach the sealed position, and the airtightness of the housing 15 can be improved.

Since the two pairs of arms 80 and 90 are linked to the movements of the two pairs of arms 60 and 70 by the interlocking mechanism 95, a wheelchair user can open one hinged door 20A with one hand and open the other hinged door 20B as well. be able to. Note that the two pairs of arms 80, 90 and the two pairs of arms 60, 70 may not be interlocked, and the hinged door 20A and the hinged door 20B may be opened and closed independently.

As described above, according to the present embodiment, the ozone treatment apparatus 10 includes the opening/closing door 20 on the front surface 15F of the housing 15, and the opening/closing door 20 is constituted by the double doors of the hinged doors 20A and 20B. The hinged door 20A is opened and closed by two pairs of arms 60 and 70, and the hinged door 20B is opened and closed by two pairs of arms 80 and 90. The hinged doors 20A and 20B move from the closed position to the side while protruding toward the front side of the housing.

Considering the handle operation by a wheelchair user, it is preferable that the amount of movement of the handles 22A and 22B in the left-right direction of the housing is within 90 cm, and even if the width of the opening 15P is set to 90 cm or more, the opening/closing operation is stable. More preferably, the length is 70 cm or less. Further, while the hinged door 20A moves from the closed position to the open position, it is preferable that the inner edge 21A1 of the hinged door 20A moves forward from the front surface 15F within a distance of 60 cm or less.

Various mechanisms can be applied to the mechanism for opening and closing the opening/closing door 20, and the movement of sliding the opening/closing door 20 in the left-right direction of the housing may be the main movement. , 70, 80, and 90 may be bent to enable greater rotation and overall sliding movement of the opening/closing door 20.

Although the opening/closing door 20 is configured with both doors in this embodiment, it may be configured with one door depending on the size of the housing 15 and the like. Furthermore, the present invention may be made into a device capable of accommodating a mobility aid such as a walker other than a wheelchair, or may be applied to an ozone treatment device of a size that cannot accommodate a wheelchair. Furthermore, the opening/closing door of this embodiment can be applied not only to ozone processing equipment that performs deodorization and sterilization processing using ozone, but also to equipment that performs deodorization, sterilization, sterilization, and the like using cleaning liquid. It is possible to apply an opening and closing mechanism.

Note that when using an excimer lamp to generate ozone, the generated ozone tends to accumulate on the bottom side of the housing, and it takes time for the ozone concentration on the top side of the housing to rise. Deodorization cannot be performed effectively. However, in this embodiment, since the opening width W of the housing 15 is larger than the housing height H, sterilization and deodorization can be effectively performed.

Therefore, it is also possible to provide an ozone treatment apparatus in which the door is opened and closed by a mechanism other than the opening and closing door described above. In other words, a housing that has a space inside that can accommodate an object to be ozonated, an ozone generator that generates ozone in the space, and an opening and closing door that can seal the opening formed in the front of the housing. It is possible to provide an ozone treatment apparatus that includes an opening/closing mechanism that moves the door in the left-right direction of the housing, and the width of the housing is larger than the height of the housing. For example, the opening width of the housing can be greater than or equal to the height of the housing (height of the opening).
